TECHNICAL FIELD

[0002] The present application relates to the field of switches, in particular to an intelligent switch. BACKGROUND

[0003] The intelligent switch is generally composed of a key, a detection piece and a wireless communication module. A user gives a control force to the key to make the key move. The key triggers the detection piece in the movement process, thereby controlling the on-off of the switch. The wireless communication module is used for receiving and sending wireless signals. The switch can also control the on-off according to the wireless signals. The rebound force of the key of the existing intelligent switch jumps obviously in the rebound process, and the displacement of the rebound jump is large, resulting in a strong paragraph feeling of the user pressing the key. SUMMARY

[0004] In order to solve the above problems, the present application provides a wall intelligent switch, a wireless intelligent switch and a switch mounting rack.

[0005] According to a first aspect of the embodiment of the present application, a wall intelligent switch is provided, comprising a shell, at least one key, a detection piece, a reset part and a wireless communication module. The key is arranged on the shell. At least part of the key can be pressed to move in response to a control force, thereby generating a displacement, so that the key passes through a first pressing position and a second pressing position in turn, and generates a reaction force. The detection piece can be triggered based on the displacement, and generates a first rebound force resisting the displacement. The reset part is arranged to support the key to deform directly or indirectly in response to the pressing movement, and generates a reset force overcoming the deformation. The wireless communication module is electrically connected with the detection piece to receive a trigger signal of the detection piece, and controls the on-off of the wall intelligent switch based on the trigger signal.

[0006] Wherein, the detection piece and the reset part cooperate to make: when the key moves to the first pressing position, the reaction force is F1, and when the key moves from the first pressing position to the second pressing position, the reaction force jumps from F1 to F2; wherein F2<F1<400g; the displacement S1 of the key at the first pressing position and the displacement S2 of the key at the second pressing position satisfy the relationship: S2-S1≤2mm.

[0007] According to a second aspect of the embodiments of the present application, a wireless intelligent switch is provided, comprising a housing, at least one key, a detection member, a reset part, and a wireless communication module. The key is arranged on the housing, and at least a part of the key is capable of being pressed to generate displacement in response to a control force, so that the key passes through a first pressing position and a second pressing position in sequence and generates a reaction force. The detection member is triggered based on the displacement and generates a first rebound force resisting the displacement. The reset part is arranged to support the key to deform directly or indirectly in response to the pressing motion and generate a reset force overcoming the deformation. The wireless communication module is in communication connection with the detection member to receive a corresponding trigger signal and send a wireless message based on the trigger signal.

[0008] Wherein, the detection member and the reset part are matched to make the reaction force F1 when the key moves to the first pressing position, and the reaction force jumps from F1 to F2 when the key moves from the first pressing position to the second pressing position; wherein, F2 < F1 < 400g; the displacement S1 of the key at the first pressing position and the displacement S2 of the key at the second pressing position satisfy the relationship S2-S1≤2mm.

[0009] According to a third aspect of the embodiments of the present application, a switch mounting frame is provided, comprising a connected frame arranged to be capable of mounting the wall intelligent switch and / or the wireless intelligent switch. At least one switch mounting position is arranged on the connected frame, and the wall intelligent switch or the wireless intelligent switch is detachably connected to the switch mounting position.

[0010] The present application has the following beneficial effects:

[0011] The wall intelligent switch and the wireless intelligent switch provided by the application, by setting the reset part matched with the key and the detection piece, the reaction force generated in the pressing process of the key is associated with the reset force provided by the reset part and the first rebound force provided by the detection piece, and the reset force and the first rebound force are configured so that the reaction force when the key is pressed from the first pressing position to the second pressing position is less than or equal to 400g, and then the pressing force required in the triggering process of the key can be controlled within 400g, so that the user presses the key more labor-saving to optimize the user experience effect. In addition, by setting the difference between the displacement of the key at the first pressing position and the second pressing position to be less than or equal to 2mm, the amount of displacement jump of the key in the pressing process is reduced to within 2mm, so that the user's sense of jamming when pressing the key is weakened, and the smoothness of the key pressing is improved. At the same time, due to the reduction of the displacement jump in the pressing process of the key, the feedback of the key triggering the detection piece is more crisp, reducing the stickiness of the key pressing, so that the key can also give the user clear feedback while improving the smoothness of the pressing.

For those skilled in the art, the specific meaning of the above-mentioned terms in the present application can be understood according to the specific circumstances.

[0127] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0128] Please refer to Figures 1-56 , based on Figures 1-56The wall intelligent switch 101 is fixedly installed on a fixed installation reference surface such as a wall or a ground, and is connected to a household power circuit and a controlled device in use, and can control the power on / off of the controlled device and has a wireless communication function, can receive a wireless message, and execute a corresponding control instruction according to the content of the wireless message to control the power on / off of the corresponding controlled device.

[0129] Specifically, as shown in Figure 1 and Figure 2 , the wall intelligent switch 101 at least comprises a housing 14, at least one button 11, a detection member 12, and a wireless communication module 13; wherein:

[0130] The button 11 is arranged on the housing 14, and at least part of the button 11 can be pressed to move in response to a control force, thereby generating a displacement, so that the button 11 at least passes through a first pressing position and a second pressing position in sequence, and generates a reaction force; the detection member 12 can be triggered based on the displacement, and generates a first rebound force resisting the displacement; the reset part 15 is arranged to support the button 11 to deform directly or indirectly in response to the pressing movement, and generates a reset force overcoming the deformation; the wireless communication module 13 is electrically connected with the detection member 12 to receive a trigger signal of the detection member 12, and controls the on / off of the wall intelligent switch 101 based on the trigger signal.

[0131] Wherein, at least part of the button 11 can be pressed to move in response to a control force should be understood as that the local part of the button 11 can be pressed to move in response to the control force, or the whole button 11 can be pressed to move in response to the control force, and the pressing movement can be, for example, a pivoting movement, a linear movement, or a composite movement of displacement plus rotation, etc. The reaction force should be understood as the reaction force in the opposite direction of the displacement generated by the part of the button 11 being pressed to move relative to the control force. The detection member 12 can be a press switch with self-resetting function, and thus can generate the first rebound force resisting the pressing of the button 11 when triggered. The wireless communication module 13 controlling the on / off of the wall intelligent switch 101 based on the trigger signal can be understood as that the wireless communication module 13 can trigger a switch on / off instruction to control the power on / off of the controlled device, and the user can control the button 11 to trigger the detection member 12, and the wireless communication module 13 controls the switch on / off according to the trigger of the detection member 12. Further, the user can also send a wireless message to the switch, and the wireless communication module 13 controls the switch on / off according to the instruction of the wireless message.

[0132] Wherein, as shown in Figure 5As shown, the detection piece 12 and the reset part 15 cooperate to make the reaction force F1 when the key 11 moves to the first pressing position, and the reaction force jumps from F1 to F2 when the key 11 moves from the first pressing position to the second pressing position; wherein F2 < F1 < 400g; the displacement S1 of the key 11 at the first pressing position and the displacement S2 of the key 11 at the second pressing position satisfy the relationship S2-S1≤2mm.

[0133] It can be seen that, by setting the reset part 15 and the detection piece 12 cooperating with the key 11, the reaction force generated by the key 11 during pressing is related to the reset force provided by the reset part 15 and the first elastic force provided by the detection piece 12, and the reset force and the first elastic force are configured to make the reaction force when the key 11 is pressed from the first pressing position to the second pressing position less than or equal to 400g, so that the pressing force required by the triggering process of the key 11 can be controlled within 400g, making the user press the key 11 more labor-saving to optimize the user experience effect. It should be noted that 400g here represents the gravity generated by a 400g object. In addition, by setting the difference between the displacements of the key 11 at the first pressing position and the second pressing position to be less than or equal to 2mm, the amount of displacement jump of the key 11 during pressing is reduced to within 2mm, so that the user's sense of jamming when pressing the key 11 is weakened, improving the smoothness of the key 11 pressing; at the same time, due to the reduction of the displacement jump of the key 11 during pressing, the feedback of the key 11 triggering the detection piece 12 is more crisp, reducing the stickiness of the key 11 pressing, so that the key 11 can also give the user clear feedback while improving the smoothness of pressing.

[0134] As shown in Figure 5 and Figures 69-76 , it is the force-displacement curve of multiple switch pressing. The applicant designs multiple switch structures, configures different models of detection pieces 12, and conducts pressure tests through a pressure machine. The contact of the pressure machine presses the key 11 to make pressing movement, and the key 11 generates displacement and reaction force during pressing. The contact of the pressure machine is provided with a force sensor and a displacement sensor, and the pressure machine records the force-displacement curve during the pressing and rebounding process of the key 11. The vertical coordinate in the figure is the value of the pressing force, and the horizontal coordinate is the displacement amount of the key 11; wherein the left side is the curve when the key 11 is pressed at the main pressing area (middle position of the key 11), and the right side is the curve when the key 11 is pressed at the corner position. There are two curves on either side, the upper one is the curve when pressing, and the lower one is the curve when rebounding. Specifically, refer to the left curve in Figure 5 and Figures 69-76 , Figure 5In the middle, F1=252.62g, S2-S1<0.2mm; Figure 69 In the middle, F1=50.25g, S2-S1<0.3mm; Figure 70 In the middle, F1=50.25g, S2-S1<0.3mm; Figure 70 In the middle, F1=102.27g, S2-S1<0.3mm; Figure 71 In the middle, F1=130.95g, S2-S1<0.6mm; Figure 72 In the middle, F1=95.49g, S2-S1<1mm; Figure 73 In the middle, F1=237.99g, S2-S1<0.2mm; Figure 74 In the middle, F1=199.55g, S2-S1<0.3mm; Figure 75 In the middle, F1=341.97g, S2-S1<0.2mm; Figure 76 In the middle, F1=264.94g, S2-S1<0.3mm. It can be seen that the reaction force of the switch structure key 11 designed by the applicant is less than or equal to 400g, and the difference between the displacement of the key 11 at the first pressing position and the second pressing position is less than or equal to 2mm. It makes the user press the key 11 more labor-saving, and improves the smooth degree of pressing the key 11.

[0135] Further, as Figure 5As shown, the reset part 15 is also arranged to drive the reset movement of the key 11 by the reset force, so that the key 11 passes through the first rebound position, the second rebound position and the third rebound position in turn; the reset force of the reset part cooperates with the first rebound force of the detection part 12, so that when the key 11 is at the first rebound position, the reaction force is F3, and when the key 11 rebounds from the first rebound position to the second rebound position, the reaction force jumps from F3 to F4, and the reaction force of the third rebound position is 0; wherein F4>F3≥22g, F2<F1, and F3 / F1>0.3. When the key 11 triggers the detection part 12, the user withdraws the control force, the key 11 generates the rebound movement, and in the rebound process of the key 11, the key 11 is subjected to the reset force of the reset part 15, the first rebound force of the detection part 12, and the elastic force generated by the deformation of the key 11 itself. At the same time, in the rebound process of the key 11, the user's finger does not separate from the surface of the key 11, and the key 11 is still subjected to the control force of the user and the supporting force of the shell 14. The key 11 generates the rebound movement under the joint action of these forces. The rebound movement is affected by the interaction between the forces, and can be uniform motion, accelerated motion, decelerated motion or compound motion. The reaction force of the key 11 is mainly composed of the reset force and the first rebound force. The applicant controls the reset force and the first rebound force, and designs the structure (see the specific key structure embodiment below), and through multiple pressing tests, when the key 11 rebounds from the first rebound position to the second rebound position, the reaction force of the key 11 is greater than or equal to 22g, which ensures that the key 11 has sufficient rebound force. Figure 5 and Figures 69-76 In the left curve in the middle, F1 is the reaction force of the key 11 when the detection part 12 jumps from the non-trigger state to the triggered state, F3 is the reaction force of the key 11 when the detection part 12 jumps from the triggered state to the non-triggered state, Figure 5 In the middle, F4>F3=180.35g, F3 / F1=0.71; Figure 69 In the middle, F4>F3=33.53g, F3 / F1=0.67; Figure 70 In the middle, F4>F3=34.95g, F3 / F1=0.34; Figure 71 In the middle, F4>F3=23.77g, F3 / F1=0.18; Figure 72 In the middle, F4>F3=35.15g, F3 / F1=0.37; Figure 73 In the middle, F4>F3=161.51g, F3 / F1=0.68; Figure 74 In the middle, F4>F3=72.39g, F3 / F1=0.36; Figure 75 In the middle, F4>F3=199.82g, F3 / F1=0.58;Figure 76 In the above figure, F4>F3=119.21g, F3 / F1=0.45. As can be seen from the above figure, the applicant controls F3 / F1>0.3 by optimizing the matching relationship between the reset force and the first rebound force, so that the force of triggering the detection member 12 during the pressing and rebounding of the button 11 will not differ too much, and the sticking feeling of the button 11 triggering the detection member 12 is reduced.

[0136] Further, the difference between F1 and F3 is less than or equal to 70g. So that the force of triggering the detection member 12 during the pressing and rebounding of the button 11 will not differ too much, and the sticking feeling of the button 11 triggering the detection member 12 is reduced, and the smoothness of the pressing and rebounding of the button 11 is improved. Further, in a preferred embodiment, the difference between F1 and F3 is less than or equal to 20g. Specifically, see Figure 69 , Figure 70 and Figure 72 in the left curve of the figure, Figure 69 In the above figure, F1-F3=16.72g; Figure 70 In the above figure, F1-F3=67.32g; Figure 72 In the above figure, F1-F3=60.34g;

[0137] Further, as Figure 6 and Figure 18As shown, the key 11 is movably connected with the shell 14; the key 11 is provided with a contact portion 113 facing the detection piece 12, for pressing and triggering the detection piece 12, the detection piece 12 is provided with a force guide piece 121 at a corresponding position of the contact portion 113, the force guide piece 121 generates movement in response to the pressing of the contact portion 113, when the force guide piece 121 moves to a preset position, the contact force between the contact portion 113 and the force guide piece 121 jumps, the connection mode of the key 11 with the shell 14 and the positional relationship of the contact portion 113 relative to the key 11 are adapted to the force guide piece 121, so that when the key 11 is pressed, the reaction force jumps from F1 to F2, and when the key 11 rebounds, the reaction force jumps from F3 to F4. The movable connection includes pivotal connection, sliding rail connection, movable buckle connection, elastic arm connection or other connection modes that can be implemented by those skilled in the art, the key 11 can be pressed to move, including pivotal movement, linear movement or composite movement of displacement plus rotation. The connection mode of the key 11 with the shell 14 and the positional relationship of the contact portion 113 relative to the key 11 are adapted to the force guide piece 121, which can be understood as follows: the applicant designs various connection structures of the key 11 with the shell 14, obtains various relative movement modes between the key 11 and the shell 14, selects appropriate connection structures through force analysis, and optimizes the structures to obtain structures meeting the pressing and rebounding characteristics of the application; the position of the contact portion 113 on the key 11 directly affects the pressing and rebounding force and displacement of the key 11, the applicant changes the position of the contact portion 113 relative to the key 11, and obtains the position meeting the pressing and rebounding characteristics of the application through force analysis, so that when the key 11 is pressed, the reaction force jumps from F1 to F2, and when the key 11 rebounds, the reaction force jumps from F3 to F4.

[0138] Further, as Figure 18As shown, the detection piece 12 further comprises an elastic force jumper 122, the force guide 121 abuts against the elastic force jumper 122 and can move relative to the detection piece 12, the elastic force jumper 122 is arranged to receive a pressing force to elastically deform and generate an elastic force, and the elastic force jumps when the pressing force reaches a preset value; when the key 11 is displaced in response to the operation force, the force guide 121 is pressed against the elastic force jumper 122 to elastically deform in response to the displacement of the key 11, when the operation force increases to F1, the pressing force of the force guide 121 acting on the elastic force jumper 122 reaches the preset value, the elastic force of the elastic force jumper 122 jumps, so that the reaction force of the key 11 jumps from F1 to F2; when the key 11 rebounds, the operation force gradually decreases to F3, the pressing force of the force guide 121 acting on the elastic force jumper 122 reaches another preset value, the elastic force of the elastic force jumper 122 jumps, so that the reaction force of the key 11 jumps from F3 to F4. Wherein, the elastic force jumper 122 can be an elastic sheet or a spring, the force guide 121 abuts against the elastic force jumper 122 and can move relative to the detection piece 12, the elastic force jumper 122 can receive a pressing force to elastically deform and generate an elastic force, and the elastic force jumps when the pressing force reaches a critical pressure, the metal contact at the right end of the elastic sheet quickly moves from the upper limit position to the lower limit position, so that the detection piece 12 switches the on-off state (i.e. is triggered). When the key 11 is displaced in response to the operation force, the key 11 directly or indirectly presses the force guide 121, the force guide 121 moves and is pressed against the elastic force jumper 122 to elastically deform, when the operation force increases to F1, the pressing force of the force guide 121 acting on the elastic force jumper 122 reaches the critical pressure, the elastic force of the elastic force jumper 122 jumps, cooperating with the reset force of the reset part 15, so that the reaction force of the key 11 jumps from F1 to F2. When the key 11 rebounds, the operation force gradually decreases, when the operation force decreases to F3, the pressing force of the force guide 121 acting on the elastic force jumper 122 reaches another critical pressure, the elastic force of the elastic force jumper 122 jumps, cooperating with the reset force of the reset part 15, so that the reaction force of the key 11 jumps from F3 to F4. The detection piece 12 can be a micro switch, a light touch switch, a membrane switch, a piezoelectric switch or other switches that can be implemented by those skilled in the art; the applicant selects the detection piece 12, brings its trigger force and trigger displacement parameters into the force analysis of the key 11 structure, obtains the model of the detection piece 12 that meets the structure of the key 11, so that the key 11 achieves the expected characteristics of pressing and rebounding.

[0139] Further, asFigure 5 and Figures 69-76 As shown, the difference between the reaction force F1 of the button 11 in the first pressed position and the reaction force F2 of the button 11 in the second pressed position is set as F3, and F3 < 0.5F1. The reset part 15, in conjunction with the detection element 12, optimizes the ratio of the reset force and the first rebound force, and improves the design of the button 11 structure and the selection of the detection element 12. This reduces the jump in the elastic force when the button 11 triggers the detection element 12, thus buffering the impact of the button 11 on the user's finger and improving the smoothness of pressing.

[0140] Furthermore, such as Figure 5 and Figures 69-76 As shown, the maximum displacement of button 11 in response to the operating force is set as S4. When button 11 is in the first pressed position, the displacement of button 11 is set as S3, wherein the operating displacement margin ratio (S4-S3) / S4≥0.2. Specifically, in designing the button 11 structure, button 11 is designed with a maximum pressing amount, i.e., the maximum displacement. When button 11 reaches the maximum pressing amount, button 11 abuts against housing 14, and button 11 is difficult to press further. The operating displacement margin ratio reflects the amount of pressure button 11 can continue to apply after triggering detection element 12. In the design of button 11 structure, the dimensional fit between button 11 and housing 14 is controlled so that the operating displacement margin ratio is greater than or equal to 0.2, ensuring that button 11 still has pressing margin after triggering detection element 12, guaranteeing successful triggering of detection element 12.

[0141] Furthermore, the control displacement margin at the corner of the button 11 is 0.5 times greater than the control displacement margin at the center of the button 11. By increasing the rigidity of the button 11 and reducing its deformation, the control displacement margin at the corner of the button 11 is kept relatively close to that at the center, thereby improving the tactile feel of pressing the button at its corner.

[0142] Furthermore, such as Figure 2As shown, the key 11 is movably connected with the shell 14, and the shell 14 can restrict at least two displacement degrees of freedom and at least one rotation degree of freedom of the key 11, so that the key 11 can have displacement and / or rotation movement and trigger the detection member 12 during the movement. The movable connection includes a pivot connection, a sliding rail connection, a movable buckle connection, an elastic arm connection or other connection modes that can be implemented by those skilled in the art. The shell 14 can restrict at least two displacement degrees of freedom and at least one rotation degree of freedom of the key 11 can be understood as that the key 11 has three displacement degrees of freedom and three rotation degrees of freedom, and the shell 14 restricts at least two displacement degrees of freedom and at least one rotation degree of freedom of the key 11, that is, the maximum movable degrees of freedom of the key 11 include one displacement degree of freedom and two rotation degrees of freedom, and the key 11 generates movement under the constraint of the shell 14, including pivot movement, linear movement or composite movement of displacement plus rotation, and the specific movement mode is determined by the connection structure of the key 11 and the shell 14.

[0143] Further, in the present embodiment, as shown in Figure 3 and Figure 4As shown, the reset part 15 is provided as at least one elastic limiting piece 151, and the shell 14 is provided with the elastic limiting piece 151 at the corresponding position of the button 11; the elastic limiting piece 151 is a cantilever beam structure, including a fixed end 1511 and a free end 1512 away from the fixed end 1511, the fixed end 1511 is fixedly connected or integrally formed with the shell 14, and the free end 1512 abuts against the button 11 to provide a reset force for the button 11. At the same time, the free end 1512 of the elastic limiting piece 151 is positioned and connected with the button 11 to limit two displacement degrees of freedom and one rotation degree of freedom of the button 11 in the horizontal direction, so that the button 11 can have a superimposed movement of displacement and rotation in the vertical direction. The shell 14 provided with the elastic limiting piece 151 at the corresponding position of the button 11 can be understood as that the elastic limiting piece 151 provided by the shell 14 can abut against the button 11 below or the side of the button 11 to provide a reset force for the button 11. The positioning and connecting can be understood as a connecting mode with positioning function, including that the button 11 and the free end 1512 are respectively provided with a positioning pin and a positioning column, the positioning pin and the positioning column are connected in cooperation to position the free end 1512 and the button 11; or the button 11 is provided with a positioning groove, the shape of the positioning groove is adapted to the free end 1512, so that the free end 1512 is positioned by the positioning groove; or other connecting modes with positioning function which can be implemented by those skilled in the art. The button 11 can have a superimposed movement of displacement and rotation in the vertical direction can be understood as that the button 11 has three displacement degrees of freedom and three rotation degrees of freedom, the shell 14 limits two displacement degrees of freedom and one rotation degree of freedom of the button 11 in the horizontal direction, and releases one displacement degree of freedom in the vertical direction and two rotation degrees of freedom in the vertical direction of the button 11, so that the button 11 can be tilted and displaced downward in response to the operation force, thereby abutting against and triggering the detection piece 12.

[0144] The intelligent switch provided by the application, the key 11 is supported by the elastic limiting piece 151 and positioned by the elastic limiting piece 151, the key 11 has higher degrees of freedom, when the key 11 is pressed, a composite motion of displacement and rotation is generated, the key 11 can be inclined towards multiple directions, so that the surface of the key 11 is more fitted to the user's fingers, and the required pressing force of the key 11 is less different at different positions, and the pressing feeling of the key 11 at different positions is more close; at the same time, the free end 1512 of the elastic limiting piece 151 can provide elastic positioning effect for the key 11, when the key 11 moves, the free end 1512 of the elastic limiting piece 151 will not slide relatively with the key 11, while the traditional rigid positioning such as buckle or positioning plate will slide relatively with the key 11 or the shell 14, causing greater frictional resistance, so that the key 11 is pressed to produce a jamming feeling. The elastic positioning scheme of the elastic limiting piece 151 is adopted in the application, the key 11 has higher flexibility, smaller movement friction and clearer pressing feedback.

[0145] Further, the detection piece 12 can adopt a micro switch, a light touch switch, a membrane switch, a piezoelectric switch or other switches that can be implemented by those skilled in the art; preferably, the detection piece 12 is a micro switch, the micro switch is also called a sensitive switch, and is commonly used for mouse keys 11. Compared with a light touch switch, the micro switch has a smaller contact spacing and is easy to trigger, generally only needs 60g of trigger force, and has lighter trigger feedback and smaller jumping displacement when triggered. The structure of the micro switch and the elastic limiting piece 151 makes the slight trigger feedback of the micro switch be transmitted, so that the smooth pressing feeling is ensured and clear trigger feedback is also obtained. The 60g can be understood as the gravity generated by a 60g object.

[0146] As Figure 5As shown in the figure, it is a key 11 pressing force-displacement curve diagram, the vertical coordinate is the value of the control force, the horizontal coordinate is the displacement of the key 11; Wherein the left side is the curve when pressing the main pressing area of the key 11 (the middle position of the key 11), the right side is the curve when pressing the corner position of the key 11, and there are two curves on either side, the upper one is the curve when pressing, and the lower one is the curve when rebounding. As can be seen from the figure, at the first rebound position, the reaction force of the key 11 is F3, and when the key 11 rebounds from the first rebound position to the second rebound position, the reaction force jumps from F3 to F4; The structure of the elastic limiting piece 151 is used with the micro switch, and the length of the elastic limiting piece 151 is designed and calculated to make F4>F3≥22g, which ensures that the key 11 has enough rebounding force, and the reaction force at the third rebound position is 0. At the same time, the displacement of the key 11 at the first rebound position is S1, and the displacement of the key 11 at the second rebound position is S2, and S1-S2≤2mm, so that when the detection piece 12 changes from the triggered state to the non-triggered state, the displacement jump of the key 11 is smaller, so that the pressing feedback is more crisp, and the pressing feeling is improved. In a specific embodiment, as shown in Figure 5 , S1-S2<0.2mm, because the detection piece 12 of the embodiment uses a micro switch, the trigger feedback is small, and the displacement jump when triggering is small. The structure of the micro switch and the elastic limiting piece 151 makes the slight trigger feedback of the micro switch be transmitted, so that the key 11 can realize smooth and clear pressing feeling. If other detection pieces 12 are used, such as a tactile switch, the trigger feedback is large, S1-S2 may even exceed 1mm, the pressing feeling is strong, and the feeling is not as good as the micro switch.

[0147] Further, as shown in Figure 3 , Figure 4 and Figure 7 , the free end 1512 is provided with a first positioning hole 1513, and the key 11 is provided with a key positioning pin 111 at the corresponding position of the first positioning hole 1513. The key positioning pin 111 is inserted into the first positioning hole 1513 to realize the positioning connection between the key 11 and the free end 1512. Wherein, the first positioning hole 1513 is a through hole, and the key positioning pin 111 is a cylindrical or circular cone-shaped protrusion, and the shaft diameter is adapted to the hole diameter of the first positioning hole 1513, so that the first positioning hole 1513 can limit the horizontal displacement of the key positioning pin 111 to position the key 11. The beneficial effect of positioning the key 11 is that it can ensure the relative position accuracy of the key 11 and the detection piece 12, avoid the positional relationship between the key 11 and the detection piece 12 from being offset, and cause the detection piece 12 to be unable to trigger; At the same time, positioning the key 11 can keep the gap between the keys 11 consistent and improve the aesthetics.

[0148] Further, the elastic limit piece 151 corresponding to each of the keys 11 has multiple, and the first positioning hole 1513 corresponding to each of the keys 11 and the key positioning pin 111 also has multiple; the key positioning pin 111 includes a root part integrally formed on the key 11, and an end part away from the root part, and the key positioning pin 111 is a circular truncated cone with a root part diameter larger than an end part diameter. The key positioning pin 111 is set as a circular truncated cone with a root part diameter larger than an end part diameter, so as to be inserted into the first positioning hole 1513, and the positioning accuracy of the key 11 can be improved; the reason is that there are multiple elastic limit pieces 151 corresponding to each key 11, and each elastic limit piece 151 has a first positioning hole 1513, when the number of the first positioning hole 1513 is three or more than three, each first positioning hole 1513 forms an over-positioning structure for the key 11, if the key positioning pin 111 is a cylinder, it will cause the key positioning pin 111 to be unable to be inserted into the first positioning hole 1513, and the conventional solution is to increase the gap between the key positioning pin 111 and the first positioning hole 1513, but this will cause the positioning accuracy to be reduced; the key positioning pin 111 of the present application adopts a circular truncated cone structure, the end part of the circular truncated cone has a guiding effect, so that the key positioning pin 111 can be smoothly inserted into the first positioning hole 1513, and after being inserted, as the key 11 approaches the shell 14, the gap between the key positioning pin 111 and the first positioning hole 1513 gradually decreases, so as to achieve the effect of accurate positioning.

[0149] In a preferred embodiment, as shown in Figure 7 , the first positioning hole 1513 is a circular truncated cone hole, the hole diameter of the side facing the key 11 is smaller than the hole diameter of the side away from the key 11, and the key positioning pin 111 is inserted into the first positioning hole 1513 and then fixed by heat melting. Among them, the hole diameter of the side of the first positioning hole 1513 facing the key 11 is smaller than the hole diameter of the side away from the key 11, which can prevent the key positioning pin 111 from falling off after being inserted into the first positioning hole 1513 and then fixed by heat melting. The heat melting fixation has the advantage of further reducing the shaking between the key 11 and the upper shell 141, improving the stability of the key 11 pressing, and further improving the positioning accuracy of the elastic limit piece 151.

[0150] Further, as shown in Figure 8 and Figure 3As shown, in the first direction, the elastic limit piece 151 corresponding to each of the keys 11 extends from the middle position of the key 11 to the edge of the key 11, and the first direction is parallel to the side surface of the key 11 and parallel to the upper surface of the key 11. Among them, the elastic limit piece 151 extending from the middle position of the key 11 to the edge of the key 11 can be understood as that the elastic limit piece 151 is integrally formed or fixedly connected to the shell 14, and the shell 14 extends the elastic limit piece 151 at the middle position of the key 11 and extends towards the edge of the key 11, and abuts against the edge position of the key 11, so that the restoring force of each elastic limit piece 151 acts on the position close to the edge of the key 11, improving the stability of the support; wherein the first direction has been shown by an arrow in Figure 8 .

[0151] Further, the elastic limit piece 151 corresponding to each of the keys 11 has four, and in the first direction, the four elastic limit pieces 151 are symmetrically distributed in pairs, and in the second direction, the four elastic limit pieces 151 are arranged in parallel in pairs; the second direction is parallel to the upper surface of the key 11, and the second direction is perpendicular to the first direction. Among them, the first direction and the second direction are as shown by the arrow in Figure 8 , the elastic limit piece 151 is symmetrically distributed in pairs and arranged in parallel in pairs, so that the elastic limit piece 151 provides symmetric restoring force to the key 11, which can adapt to the composite motion of displacement and rotation of the key 11, and the key 11 can be inclined in multiple directions, and the symmetric restoring force provided by the elastic limit piece 151 can make the key 11 receive similar restoring force when it is inclined in any direction by the control force.

[0152] At the same time, the symmetric restoring force provided by the four elastic limit pieces 151 makes it easy to control the restoring force through structural design, and the applicant controls the restoring force and the elastic force of the detection piece 12 by changing the angle, thickness, width and length of the elastic limit piece 151 through calculation simulation, so that when the key 11 moves to the first pressing position, the reaction force is F1, and when the key 11 moves from the first pressing position to the second pressing position, the reaction force jumps from F1 to F2; wherein F2

[0153] Further, the extension direction of the elastic limit piece 151 is parallel to one side of the key 11, so that the space occupied by the elastic limit piece 151 in the second direction is reduced, and space is reserved for the shell 14 to arrange other components

[0154] Further, as shown in Figure 8 and Figure 3 , in the first direction, the length of the elastic limiting piece 151 is greater than 1 / 4 of the length of the key 11. Since in the first direction, the four elastic limiting pieces 151 are symmetrically distributed two by two, the elastic limiting piece 151 extends from the middle position of the key 11 to the edge position of the key 11, so the length of the control elastic limiting piece 151 is greater than 1 / 4 of the length of the key 11, so that the elastic limiting piece 151 is as long as possible in the implementation case, and when the thickness of the elastic limiting piece 151 is constant, the longer the length is, the better the flexibility is, and the less likely the fracture is.

[0155] Further, as shown in Figure 9 , Figure 4 and Figure 3 , the root of the key positioning pin 111 is provided with a reinforcing seat 116, and when the key positioning pin 111 is inserted into the first positioning hole 1513, the reinforcing seat 116 abuts against the elastic limiting piece 151. Wherein, since the root of the key positioning pin 111 is prone to stress concentration and fracture, the reinforcing seat 116 is arranged at the root of the key positioning pin 111, which can prevent the root of the key positioning pin 111 from breaking. In a specific embodiment, as shown in Figure 9 and Figure 10 , the reinforcing seat 116 is provided with four reinforcing units 1161, which are uniformly distributed along the circumference of the root of the key positioning pin 111; the reinforcing unit 1161, the key positioning pin 111 and the key 11 are integrally formed. Specifically, the reinforcing unit 1161 is a square connecting block. The reinforcing seat 116 can strengthen the strength of the root of the key positioning pin 111 and prevent it from breaking, and at the same time, the four reinforcing units 1161 are uniformly distributed along the circumference of the key positioning pin 111, so that the key positioning pin 111 is not easy to be skewed during injection cooling, and the positioning accuracy of the key positioning pin 111 is improved.

[0156] Further, as shown in Figure 7 , one side of the elastic limiting piece 151 towards the key 11 is parallel to the key 11 at the corresponding position of the first positioning hole 1513. That is, the upper surface of the free end 1512 of the elastic limiting piece 151 is parallel to the lower surface of the key 11, so as to keep the first positioning hole 1513 in a vertical state during injection molding, facilitate the key positioning pin 111 to be inserted into the first positioning hole 1513, and improve the positioning accuracy of the first positioning hole 1513; at the same time, when the key positioning pin 111 is inserted into the first positioning hole 1513, the upper surface of the elastic limiting piece 151 is attached to the key 11 at the corresponding position of the first positioning hole 1513, and the elastic limiting piece 151 and the key 11 adopt surface contact, which improves the stability of the elastic limiting piece 151 supporting the key 11.

[0157] Further, as shown in Figure 8 The elastic limiting piece 151 is extended from the shell 14, and the fixed end 1511 is integrally formed with the shell 14. Since the elastic limiting piece 151 is integrally formed with the shell 14, there is no need to additionally set a reset piece, which simplifies the structure, reduces the cost, reduces the number of parts, and reduces the assembly steps. As shown in Figure 7 The elastic limiting piece 151 is a long strip-shaped structure, and the thickness thereof is smaller than the thickness of the shell 14, as shown in Figure 12 and Figure 8 The width of the two ends is wider than the width of the middle part; the elastic limiting piece 151 can elastically deform in response to the pressure of the key 11, and the elastic deformation of the elastic limiting piece 151 recovers when the pressure is removed. Among them, the shell 14 needs to have a certain rigidity, and the elastic limiting piece 151 needs to have a certain flexibility. Since the elastic limiting piece 151 is extended from the shell 14, the thickness of the elastic limiting piece 151 is made thin, so that the rigidity of the shell 14 is ensured, and the elastic limiting piece 151 has a certain flexibility. The width of the two ends being wider than the width of the middle part can be understood as that, in the second direction, the width of the connecting part 1197 of the elastic limiting piece 151 and the shell 14 and the width of the end part are widened. Since the elastic limiting piece 151 has a cantilever beam structure, the connecting part of the elastic limiting piece 151 and the shell 14 is prone to breakage. Therefore, the width of the two ends of the elastic limiting piece 151 is controlled to be wider than the width of the middle part, so that the strength of the connecting part 1197 of the elastic limiting piece 151 and the shell 14 is enhanced, preventing the breakage due to excessive stress. At the same time, the width of the middle part is narrowed, which can ensure the flexibility of the elastic limiting piece 151. At the same time, the end part of the elastic limiting piece 151 is widened, so that the first positioning hole 1513 is increased, and the diameter of the key positioning pin 111 is further increased, preventing the breakage of the key positioning pin 111.

[0158] Further, as shown in Figure 7 and Figure 8 The elastic limiting piece 151 is extended along the direction towards the key 11, the side of the key 11 towards the shell 14 is set as a first surface, and the angle between the extension direction of the elastic limiting piece 151 and the first surface of the key 11 is less than or equal to 40°. Among them, the first surface is Figure 7The lower surface of the middle button 11 is inclined to extend in the direction of the button 11, the elastic limiting member 151 can lift the button 11 upward by a certain height, so that the button 11 has a certain downward space, and ensures that the button 11 can smoothly trigger the detection member 12. At the same time, since the elastic limiting member 151 abuts against the reinforcing seat 116 of the button positioning pin 111, the height of the elastic limiting member 151 combined with the height of the reinforcing seat 116 is the height of the button 11 being lifted, so that the upward lifting of the elastic limiting member 151 can prevent the reinforcing seat 116 from being too high and tilted, affecting the positioning accuracy. The angle between the extension direction of the elastic limiting member 151 and the first surface of the button 11 can be understood as Figure 7 The angle between the extension direction of the elastic limiting member 151 and the upper surface of the shell 14 is less than or equal to 40°, which can prevent the elastic limiting member 151 from being difficult to bend and deform or being broken during bending due to the too large angle. In a specific embodiment, the angle is equal to 7.9°.

[0159] In a preferred embodiment, the middle part of the elastic limiting member 151 is bent by an arc (not shown in the figure), and the center of the arc is away from the button 11. When the button 11 is pressed, the button 11 moves towards the shell 14, and the elastic limiting member 151 is deformed towards the shell 14. When the middle part of the elastic limiting member 151 is bent by an arc, the center of the arc is away from the button 11, so that the middle part of the elastic limiting member 151 is not easy to break when it is deformed.

[0160] Further, as shown in Figure 7 and Figure 8 The connection between the elastic limiting member 151 and the shell 14 adopts a circular arc transition. Since the elastic limiting member 151 is inclined towards the button 11, the connection between the elastic limiting member 151 and the shell 14 is a bending point, which is easy to concentrate stress. The circular arc transition can reduce stress concentration and prevent the elastic limiting member 151 from being broken.

[0161] In another embodiment, the surface of the shell 14 on the side facing the button 11 is a second surface, the extension direction of the elastic limiting member 151 is parallel to the second surface (not shown in the figure), and the surface of the elastic limiting member 151 on the side facing the button 11 is coplanar with the second surface. The second surface is the upper surface of the shell 14. In this embodiment, the upper surface of the elastic limiting member 151 is parallel and coplanar with the upper surface of the shell 14, so that the elastic limiting member 151 extends horizontally out of the shell 14. When the elastic limiting member 151 is bent downward under pressure, it is not easy to have a tearing point, and the connection between the elastic limiting member 151 and the shell 14 does not bend in the vertical direction, so that the stress concentration phenomenon at this connection is weakened, so that the elastic limiting member 151 is not easy to break. Correspondingly, the height of the reinforcing seat 116 of the button positioning pin 111 matches the triggering displacement of the detection member 12, so that the reinforcing seat 116 abuts against the elastic limiting member 151 and lifts the button 11 by a height, so that the button 11 has a certain pressing space to successfully trigger the detection member 12.

[0162] Further, as shown in Figure 3 the shell 14 is provided with a relief portion 1411 on the side away from the button 11. The relief portion 1411 is provided in a shape matching the through hole or groove of the elastic limiting member 151. The elastic limiting member 151 deforms in response to the pressing of the button 11, and at least part of it is accommodated in the relief portion 1411. The shell 14 is provided with a relief portion 1411 on the side away from the button 11. It can be understood that the upper surface of the shell 14 is provided with the relief portion 1411 at the corresponding position of the elastic limiting member 151. The relief portion 1411 is provided in a shape matching the through hole or groove of the elastic limiting member 151. It can be understood that the size of the relief portion 1411 is slightly larger than that of the elastic limiting member 151, so that the elastic limiting member 151 can be accommodated in the relief portion 1411. In a specific embodiment, as shown in Figure 12 the elastic limiting member 151 includes a first side, a second side, and a third side. The shell 14 is provided with a first strip-shaped through hole 1412 at the corresponding position of the first side, a second strip-shaped through hole 1413 at the corresponding position of the second side, and a third strip-shaped through hole 1414 at the corresponding position of the third side. The first strip-shaped through hole 1412 and the second strip-shaped through hole 1413 are oppositely arranged, and the third strip-shaped through hole 1414 is oppositely arranged with the fixed end 1511 of the elastic limiting member 151. The first strip-shaped through hole 1412, the second strip-shaped through hole 1413, and the third strip-shaped through hole 1414 are connected to each other to divide the shell 14 into the elastic limiting member 151, Figure 7 and Figure 3As shown, the elastic limiting piece 151 is raised towards the key 11, so that the shell 14 forms the avoiding part 1411 at the corresponding position of the elastic limiting piece 151. The elastic limiting piece 151 is integrally formed by injection molding of the shell 14, the first, second and third strip-shaped through holes 1412, 1413 and 1414 are formed by cutting when the shell 14 is injection molded, and the shell 14 is reserved with a space below the elastic limiting piece 151 when injection molding, and the elastic limiting piece 151 is raised upwards to form the avoiding part 1411 below the elastic limiting piece 151.

[0163] In another embodiment, the key 11 is provided with a first positioning groove (not shown in the figure) towards the elastic limiting piece 151, the width and length of the first positioning groove are respectively adapted to the width and length of the elastic limiting piece 151, when the key 11 is installed on the shell 14, the first positioning groove is sleeved on the free end 1512 of the elastic limiting piece 151, so that the first positioning groove is positioned by the elastic limiting piece 151 to realize the positioning connection between the key 11 and the free end 1512. Specifically, the elastic limiting piece 151 is a rectangular strip structure, the key 11 has a certain thickness, the first positioning groove is formed on the lower surface of the key 11, and the first positioning groove is a rectangular groove with a size slightly larger than the elastic limiting piece 151, so that the elastic limiting piece 151 is gap-fitted with the first positioning groove, and then the first positioning groove can be completely sleeved into the elastic limiting piece 151, and the elastic limiting piece 151 abuts against the top wall of the first positioning groove. Further, when the first limiting groove is sleeved on the elastic limiting piece 151, the gap between the side wall of the elastic limiting piece 151 and the side wall of the first limiting groove is less than 0.1 mm, so as to prevent the positioning accuracy from being poor due to the too large gap. In another preferred embodiment, the first positioning groove is a ladder-shaped groove with the size of the lower end larger than that of the upper end, so that the first positioning groove is sleeved into the elastic limiting piece 151, and the upper end of the first positioning groove is transitionally fitted with the elastic limiting piece 151, when the elastic limiting piece 151 abuts against the top wall of the first positioning groove, the gap between the first positioning groove and the elastic limiting piece 151 is reduced, so that the positioning accuracy is greatly increased.

[0164] Further, as shown in FIG. 6, the key 11 is provided with a second positioning groove (not shown in the figure) towards the elastic limiting piece 151, the width and length of the second positioning groove are respectively adapted to the width and length of the elastic limiting piece 151, when the key 11 is installed on the shell 14, the second positioning groove is sleeved on the free end 1512 of the elastic limiting piece 151, so that the second positioning groove is positioned by the elastic limiting piece 151 to realize the positioning connection between the key 11 and the free end 1512. Figure 3 and Figure 9As shown, the key 11 is provided with a plurality of key buckles 112 towards the shell 14, and the shell 14 is provided with a plurality of buckle positions 1415 corresponding to the key buckles 112, which are adapted to the key buckles 112. The key buckles 112 are buckled into the buckle positions 1415, so that the limit position of the upward movement of the key 11 is limited. The key buckles 112 are integrally extended from the key 11, or the key buckles 112 are fixedly connected to the key 11. The shell 14 is provided with a plurality of buckle positions 1415 corresponding to the key buckles 112, which can be understood as that the buckle positions 1415 are located directly below the key buckles 112, and the shape of the buckle positions 1415 is adapted to the end of the key buckles 112, and is slightly larger than the end of the key buckles 112, so that the key buckles 112 cannot be separated from the buckle positions 1415 after being buckled into the buckle positions 1415. The plurality of key buckles 112 can be understood as that each key 11 is provided with three, four, six, eight or other number of key buckles 112, and the key buckles 112 are uniformly distributed around the key 11. Specifically, when the key buckles 112 are three, the key 11 can be triangular (not shown in the figure), and the key buckles 112 are arranged at the three corners of the triangular key 11. When the key buckles 112 are four, the key 11 can be quadrangular, and the key buckles 112 are arranged at the four corners of the quadrangular key 11. When the key buckles 112 are six or eight (not shown in the figure), the key 11 can be quadrangular, and the key buckles 112 are symmetrically distributed on the four sides of the key 11. In this embodiment, the surface of the key 11 towards the shell 14 is rectangular, the key buckles 112 are four, and are arranged at the four corners of the rectangular key 11 and are extended from the key 11 towards the shell 14. The key buckles 112 are arranged at the four corners of the key 11, so that the key buckles 112 symmetrically limit the key 11 at the four corners of the key 11, can adapt to the composite movement of displacement and rotation of the key 11, are beneficial to the inclination of the key 11 towards multiple directions, when one corner of the key 11 is controlled by the operating force, the corner generates displacement downwards, and the key buckles 112 which are symmetrically distributed with the corner act as fulcrums to prevent the key 11 from being raised upwards, and facilitate the triggering of the detection member 12 by the key 11. Meanwhile, the symmetric limitation provided by the key buckles 112 can make the restoring force of the key 11 be similar when the key 11 inclines towards different directions. Furthermore, the key buckles 112 are arranged at the four corners of the key 11, so that the distance between the key buckles 112 is larger. Due to the machining error, the height of each key buckle 112 has error, and the height of the buckle position 1415 also has error, which causes the upper surface of the key 11 to be not horizontal, and increasing the distance between the key buckles 112 can reduce the influence of the height error on the horizontal degree of the upper surface of the key 11.

[0165] Further, as Figure 9 andFigure 10 As shown, the end of the button latch 112 is provided with a hook portion 1121. The button latch 112 is hooked to the lower edge of the fastening position 1415 through the hook portion 1121 to limit the extreme position of the upward movement of the button 11. The orientation of the hook portion 1121 is set from the four corners of the button 11 to the center of the button 11. The hook portion 1121 can be understood as a hook-shaped structure extending laterally from the end of the button latch 112. When the button latch 112 is fastened into the fastening position 1415, the hook-shaped structure of the hook portion 1121 hooks the lower edge of the fastening position 1415, so that the button latch 112 cannot disengage from the fastening position 1415 upwards. When the corner of button 11 is pressed, the button latch 112 located diagonally opposite the pressing area acts as a fulcrum and is inclined towards the outside of button 11. The hook portion 1121 facing the inside of button 11 can prevent the button latch 112 from interfering with the housing 14, thus affecting the pressing feel. Furthermore, the hook portion 1121 is inclined relative to the side of button 11, so that the four button latches 112 cooperate with each other to restrict the horizontal displacement and rotation of button 11, thus positioning button 11. Since the positioning accuracy of button latch 112 is relatively low, if the positioning function of button latch 112 is relied on only, without the use of elastic limiting member 151 for limiting, button 11 can make a small distance displacement in the horizontal direction, resulting in uneven gaps between buttons 11. It is necessary to reduce the fit gap between button latch 112 and housing 14 to improve the positioning accuracy of button latch 112. This will increase the friction between button latch 112 and housing 14, increasing the pressing resistance. This invention uses a button latch 112 in conjunction with an elastic limiting member 151. The button latch 112 pre-positions the button positioning pin 111 so that it aligns with the first positioning hole 1513 of the elastic limiting member 151. This facilitates the insertion of the button positioning pin 111 into the first positioning hole 1513. The elastic limiting member 151 serves as the main positioning element, which not only improves the positioning accuracy of the buttons 11 and ensures consistent gaps between the buttons 11, but also prevents friction between the button latch 112 and the housing 14, thus avoiding increased resistance and a sticky feeling when pressing the buttons 11.

[0166] Furthermore, such as Figure 10As shown, one side of the key 11 towards the shell 14 is provided as a first surface, the projection of the key buckle 112 on the first surface is a first circular arc, the center of the first circular arc points towards the direction of the key buckle 112, and correspondingly, the projection of the hook part 1121 on the first surface is a second circular arc, the center of the second circular arc is the same as the center of the first circular arc. The circular arc buckle can further prevent the key 11 from being separated from the shell 14, and provide symmetrical limiting for the key 11 to adapt to the pressing of the key 11 in each direction. Correspondingly, the projection of the buckling position 1415 on the upper surface of the shell 14 is a sector, and the arc edge of the sector matches the arc shape of the key buckle 112; as shown in Figure 3 As shown, the buckling position 1415 is a through hole, and a first guide inclined surface 14151 is arranged at the arc position of the sector towards the side of the key 11, so as to facilitate the key buckle 112 to be buckled into the buckling position 1415.

[0167] Further, as shown in Figure 11 The shell 14 is provided with a buckle moving space 1421 at the corresponding position of the buckling position 1415, and the moving space is provided as a groove matching the shape of the buckling position 1415, so as to prevent the key buckle 112 from interfering with the shell 14 during movement. Specifically, the shell 14 includes an upper shell 141 and a lower shell 142, the key 11 is arranged on the upper shell 141, and correspondingly, the upper shell 141 is provided with the buckling position 1415, and the lower shell 142 is provided with a groove matching the shape of the key buckle 112 below the buckling position 1415, so as to form the buckle moving space 1421.

[0168] Further, as shown in Figure 3 , Figure 6 and Figure 9As shown, the key 11 is provided with a contact portion 113 at a position corresponding to the detection member 12, and when the key 11 is displaced in response to the operation force, the contact portion 113 directly or indirectly presses and triggers the detection member 12. The direct or indirect pressing and triggering of the detection member 12 by the contact portion 113 can be understood as follows: the contact portion 113 is arranged above the detection member 12 and can directly press the detection member 12; or a waterproof silica gel sleeve is arranged between the contact portion 113 and the detection member 12, and the detection member 12 is triggered indirectly by pressing the waterproof silica gel sleeve; or a buffer member is arranged between the contact portion 113 and the detection member 12, and the detection member 12 is triggered by the contact portion 113 through the buffer member, and the buffer member is used to prevent the key 11 from being damaged due to excessive pressing force. Specifically, the detection member 12 is arranged below the center of the key 11, and the center of the key 11 integrally extends downward to form the contact portion 113. Further, in the third direction, the length of the key buckle 112 is matched with the length of the contact portion 113, so that when the key 11 is not displaced, the gap between the contact portion 113 and the detection member 12 is less than or equal to 1.5 mm; the third direction is the direction in which the key 11 points to the shell 14. When the key 11 is not pressed, the key buckle 112 hooks the buckle position 1415 to limit the upward movement of the key 11 and prevent the key 11 from being separated from the shell 14, and the gap between the contact portion 113 and the detection member 12 is less than or equal to 1.5 mm, that is, the idle stroke of the key 11 is less than or equal to 1.5 mm, which improves the pressing feeling of the key 11; in this embodiment, the gap between the contact portion 113 and the detection member 12 is 0.1 mm. The purpose of reserving the gap between the contact portion 113 and the detection member 12 is to prevent the detection member 12 from being pre-pressed due to assembly error, and even to prevent false triggering. Further, the limit value of the displacement of the key 11 is greater than or equal to 1.2 mm, and when the displacement reaches the limit value, at least part of the key 11 abuts against the shell 14. In this embodiment, the edges of the key 11 extend to the key 11 surrounding portion towards the shell 14, and the key 11 surrounding portion is surrounded to shield part of the shell 14; wherein in the third direction, the distance between the key 11 surrounding portion and the shell 14 is greater than or equal to 1.2 mm, so that the limit value of the displacement of the key 11 is greater than or equal to 1.2 mm.The key 11 surrounding part surrounds part of the shell 14, which can improve the appearance of the key 11. In this embodiment, the gap between the key 11 surrounding part and the shell 14 is controlled so that the limit stroke of the key 11 is 1.6mm. If the edge of the key 11 is pressed, according to the principle of the lever, the edge of the key 11 is pressed 1.6mm, which can make the abutting part 113 press 0.8mm. The detection piece 12 is a micro switch, and the theoretical touch stroke is 0.3mm. In theory, the abutting part 113 is pressed 0.4mm to trigger the detection piece 12. In actual production, the cumulative tolerance of assembly and the deformation of the key 11 may make the reserved 0.1mm gap larger. Therefore, the pressing stroke of the abutting part 113 at the edge of the key 11 is designed to be 0.8mm in the theoretical design. There is an extra 0.4mm pressing stroke, which can ensure that the detection piece 12 can still be successfully triggered when the edge of the key 11 is pressed.

[0169] Further, as shown in Figure 9 and Figure 10 , the abutting part 113 is a column body extending from the key 11 towards the detection piece 12, and the cross section perpendicular to the extension direction is set as a first cross section. The shape of the first cross section is set as two mutually intersecting and perpendicular rectangles. The first shape can be understood as a shape similar to a "cross", which prevents shrinkage caused by local glue thickness of the abutting part 113 during injection molding, resulting in that the detection piece 12 cannot be triggered.

[0170] In another embodiment, as shown in Figure 30 , Figure 31 and Figure 32 , the free end 1512 of the elastic limiting piece 151 extends to the abutting part 113 towards the detection piece 12. When the key 11 generates the displacement in response to the operation force, the key 11 abuts against the elastic limiting piece 151 to generate the deformation, and the elastic limiting piece 151 drives the abutting part 113 to trigger the detection piece 12. In this embodiment, the elastic limiting piece 151 corresponding to each key 11 is one, the elastic limiting piece 151 is a cantilever beam structure, and the end of the elastic limiting piece 151 extends to the abutting part 113 towards the side of the key 11. Figure 31 and Figure 32As shown, the elastic limiting piece 151 is provided with a receiving portion 1514 at a position corresponding to the abutting portion 113 and protruding towards the key 11, the receiving portion 1514 is provided in a circular arc shape and used for abutting against the key 11 and driving the elastic limiting piece 151 to deform, when the key 11 is displaced in response to the operation force, the lower surface of the key 11 abuts against and drives the abutting portion 113 to trigger the detection piece 12. The beneficial effects of the embodiment are that the abutting portion 113, the elastic limiting piece 151 and the shell 14 are integrally formed, the relative position accuracy between the abutting portion 113 and the shell 14 is ensured, and since the detection piece 12 is mounted on the shell 14, the positioning accuracy between the abutting portion 113 and the detection piece 12 is ensured; compared with the abutting portion 113 arranged on the key 11, the abutting portion 113 is arranged on the elastic limiting piece 151 in the embodiment, the error size chain between the abutting portion 113 and the detection piece 12 is shortened, the positioning accuracy between the abutting portion 113 and the detection piece 12 is more easily ensured, and thus the manufacturing accuracy requirement is reduced. There is no positioning relationship between the key 11 and the detection piece 12, the positioning accuracy requirement of the key 11 is reduced, there is no positioning structure between the key 11 and the elastic limiting piece 151, and thus the manufacturing cost of the key 11 and the elastic limiting piece 151 is reduced.

[0171] Meanwhile, the relative position accuracy between the abutting portion 113 and the detection piece 12 is controlled to be very high in the above structure, and a single elastic limiting piece 151 is used to provide a reset force, so that the reset force is easy to control and can be calculated, and since the elastic limiting piece 151 is a cantilever beam structure, the calculation reliability of the reset force is high. The applicant changes the lifting angle, thickness, width and length of the elastic limiting piece 151, calculates and simulates, controls the reset force and the elastic force of the detection piece 12 to match, so that when the key 11 moves to the first pressing position, the reaction force is F1, and when the key 11 moves from the first pressing position to the second pressing position, the reaction force jumps from F1 to F2; wherein F2

[0172] Further, the upper shell 141 is provided with a light uniformizing cover light transmission hole 1419 at a position corresponding to the detection piece 12, and the abutting portion 113 can abut against the detection piece 12 after passing through the light uniformizing cover light transmission hole 1419. The light uniformizing cover light transmission hole 1419 is also used for the light uniformizing cover 183 to pass through, and the technical details of the light uniformizing cover 183 and the light uniformizing cover light transmission hole 1419 will be described in detail below.

[0173] In the embodiment, there is no positioning structure between the key 11 and the elastic limiting piece 151, the key 11 is positioned by the shell 14, and specifically, as shown in Figure 30and Figure 33 As shown, the button 11 is provided with four button latches 112 facing the housing 14. Each button latch 112 has a hook portion 1121 at its end. The housing 14 has corresponding engagement positions 1415 adapted to the button latches 112. When the button latch 112 is engaged with the engagement position 1415, the button latch 112 hooks the edge of the engagement position 1415 through the hook portion 1121, thus limiting the maximum upward movement of the button 11. The hook portions 1121 of any two adjacent button latches 112 are perpendicular to each other. This can be understood as the hook portions 1121 of the four button latches 112 being oriented opposite each other, and the hook portions 1121 of two adjacent button latches 112 being perpendicular to each other. Specifically, the upper surface of button 11 is square, and there are four button latches 112 distributed at the four corners of button 11. The corresponding hooks 1121 of the four button latches 112 are set from the four corners of button 11 toward the center of button 11. Thus, the four button latches 112 mutually restrict and cooperate with each other in the horizontal direction, which can limit the horizontal displacement and rotation of button 11, so that the housing 14 positions button 11.

[0174] In another embodiment, such as Figures 34-37 As shown, the reset part 15 is configured with at least one elastic reset member 152. The elastic reset member 152 is disposed between the button 11 and the housing 14, and can elastically deform in response to the displacement of the button 11, generating a reset force to overcome the elastic deformation. The elastic reset member 152 can be understood as an elastic component, including but not limited to springs, torsion springs, spring sheets, elastic foam, silicone, etc. The placement of the elastic reset member 152 between the button 11 and the housing 14 can be understood as follows: the elastic reset member 152 is installed on the button 11 or the housing 14, and is clamped between the button 11 and the housing 14. The elastic reset member 152 simultaneously abuts against the lower surface of the button 11 and the upper surface of the housing 14. When the button 11 presses against the elastic reset member 152, the elastic deformation occurs, and the elastic reset member 152 generates a reset force to overcome the elastic deformation, supporting the button 11 to return to its initial position.

[0175] Furthermore, such as Figure 35 and Figure 36As shown, the elastic reset member 152 is a spring 1521; the key 11 extends out of a spring limiting portion 118 in the relative position of the spring 1521 towards the shell 14, the spring 1521 is sleeved on the spring limiting portion 118, so that the spring 1521 is limited in the horizontal direction. The spring limiting portion 118 can be understood as a column extending downward from the key 11, which is slightly smaller than the inner diameter of the spring 1521, so that the spring 1521 is sleeved on the spring limiting portion 118 and is limited.

[0176] Further, as shown in Figure 36 The key 11 towards the shell 14 is rectangular, the spring limiting portion 118 has four, distributed at the four corners of the rectangle, and the spring 1521 also has four, respectively sleeved on the four spring limiting portions 118. Among them, the spring limiting portion 118 is distributed at the four corners of the rectangle, which can balance the support of the key 11, adapt to the composite motion of displacement and rotation of the key 11, and the key 11 can be inclined in multiple directions. The symmetrical reset force provided by the elastic reset member 152 can make the key 11 receive similar reset force when it is inclined in any direction by the operating force.

[0177] At the same time, since the spring force provided by the spring 1521 is proportional to the compression amount, and the symmetrical reset force provided by the four springs 1521 makes the reset force easy to control and can be calculated, the applicant controls the spring force of the spring 1521 by testing the elastic coefficient of various types of springs 1521. After calculation and simulation, the reset force and the spring force of the detection member 12 are matched, so that when the key 11 moves to the first pressing position, the reaction force is F1, and when the key 11 moves from the first pressing position to the second pressing position, the reaction force jumps from F1 to F2; Wherein, F2 < F1 < 400g; and the displacement S1 of the key 11 at the first pressing position and the displacement S2 of the second pressing position satisfy the relationship: S2-S1≤2mm.

[0178] Further, as shown in Figure 35 And Figure 37As shown, the shell 14 is provided with a clearance position 143 corresponding to the position of the spring limiting portion 118. When the key 11 is displaced in response to the operating force, the key 11 drives the spring limiting portion 118 to move, and the clearance position 143 provides clearance space at the corresponding position of the spring limiting portion 118 to prevent the spring limiting portion 118 from interfering with the shell 14. The clearance position 143 can be understood as a through hole formed in the shell 14 and having a shape matching the spring limiting portion 118, and the spring limiting portion 118 is inserted into the clearance position 143 and can move in the clearance position 143. Specifically, the spring limiting portion 118 is a cylinder, and the clearance position 143 is a cylindrical through hole. A gap is provided between the inner wall of the clearance position 143 and the side wall of the spring limiting portion 118 to prevent the clearance position 143 from interfering with the spring limiting portion 118 when the key 11 is pressed obliquely. However, the gap between the clearance position 143 and the spring limiting portion 118 should not be too large, because the clearance position 143 has a positioning effect on the spring limiting portion 118. The key 11 is positioned by the clearance position 143, so that the gaps between the keys 11 are uniform. In a specific embodiment, the gap between the inner wall of the clearance position 143 and the side wall of the spring limiting portion 118 is 0.2 mm.

[0179] Further, as shown in Figure 35 and Figure 36 , one end of the spring limiting portion 118 towards the key 11 is in interference fit with the spring 1521, and the other end of the spring limiting portion 118 away from the key 11 is in clearance fit with the spring 1521. The interference fit between the one end of the spring limiting portion 118 towards the key 11 and the spring 1521 allows the spring 1521 to be sleeved on the spring limiting portion 118, and the one end of the spring 1521 towards the key 11 is clamped to the root of the spring limiting portion 118, preventing the spring 1521 from falling off during assembly, so that the key 11 can be installed on the shell 14. In addition, the clearance fit between the other end of the spring limiting portion 118 away from the key 11 and the spring 1521 allows the spring 1521 to compress without interfering with the spring limiting portion 118, ensuring the smoothness of compression and recovery of the spring 1521. In a specific embodiment, as shown in Figure 35 , the spring limiting portion 118 is a cylinder, and the spring 1521 is a circular truncated cone with a smaller diameter at the upper end and a larger diameter at the lower end. The upper end of the spring 1521 is arranged towards the key 11, and the lower end of the spring 1521 is arranged away from the key 11. The diameter of the upper end of the spring 1521 is smaller than the shaft diameter of the spring limiting portion 118, so that the upper end of the spring 1521 is in interference fit with the spring limiting portion 118. The diameter of the lower end of the spring 1521 is larger than the shaft diameter of the spring limiting portion 118, so that the lower end of the spring 1521 is in clearance fit with the spring limiting portion 118.

[0180] In another specific embodiment, the spring 1521 is cylindrical (not shown in the figure), and the spring limiting portion 118 is a circular truncated cone with a larger diameter at the upper end than at the lower end, the upper end of the spring limiting portion 118 is arranged towards one end of the key 11, and the lower end of the spring limiting portion 118 is arranged away from one end of the key 11; the diameter of the upper end of the spring limiting portion 118 is larger than the shaft diameter of the spring limiting portion 118, so that the upper end of the spring limiting portion 118 is in interference fit with the spring 1521; the diameter of the lower end of the spring limiting portion 118 is smaller than the shaft diameter of the spring 1521, so that the lower end of the spring limiting portion 118 is in clearance fit with the spring 1521.

[0181] Further, as shown in Figure 37 and Figure 35 The key 11 is provided with four key buckles 112 towards the shell 14, the end of the key buckle 112 is provided with a hook portion 1121, and the shell 14 is provided with a buckle position 1415 corresponding to the key buckle 112 at the corresponding position of the key buckle 112, when the key buckle 112 is buckled into the buckle position 1415, the key buckle 112 hooks the edge of the buckle position 1415 through the hook portion 1121 to limit the limit position of the upward movement of the key 11; wherein the setting direction of the hook portion 1121 of any two adjacent key buckles 112 is perpendicular to each other. The setting direction of the hook portion 1121 of any two adjacent key buckles 112 being perpendicular to each other can be understood as that the corresponding hook portions 1121 of the four key buckles 112 are arranged towards each other in pairs, and the corresponding hook portions 1121 of the two adjacent key buckles 112 are perpendicular to each other. Specifically, the upper surface of the key 11 is square, the key buckle 112 has four, which are distributed at the four corners of the key 11, and the corresponding hook portions 1121 of the four key buckles 112 are arranged towards the center of the key 11 from the four corners of the key 11. Thus, the four key buckles 112 restrict and cooperate with each other in the horizontal direction, which can limit the displacement and rotation of the key 11 in the horizontal direction, so that the key 11 is positioned by the key buckle 112. Although the clearance position 143 on the shell 14 has a positioning effect on the key 11, but due to the large gap between the clearance position 143 and the side wall of the spring limiting portion 118, the positioning accuracy is not high, so the positioning effect of the key buckle 112 on the key 11 is added to improve the positioning accuracy of the shell 14 on the key 11.

[0182] Further, as shown in Figure 34As shown, the length of the spring 1521 matches the length of the key buckle 112, so that the spring 1521 is in a compressed state when the key 11 does not generate the displacement. The length of the spring 1521 matching the length of the key buckle 112 can be understood as that the spring 1521 is clamped between the key 11 and the shell 14, and the length of the key buckle 112 determines the spacing between the key 11 and the shell 14. The length of the key buckle 112 is controlled so that the spacing between the key 11 and the shell 14 is less than the length of the spring 1521 in a natural state, so that the spring 1521 is installed between the key 11 and the shell 14 in a compressed state. The beneficial effect is that the spring 1521 has a pre-tightening force on the key 11, so that the key 11 is still supported by the spring 1521 when it is not pressed, ensuring that the key 11 is in the upper limit position when it is not pressed, improving the flatness of the upper surface of each key 11, and improving the tightness of the key 11, without appearing loose and sagging.

[0183] Further, as shown in Figure 36 The key 11 is provided with a contact portion 113 at a corresponding position of the detection piece 12, and when the key 11 generates the displacement in response to the control force, the contact portion 113 directly or indirectly presses and triggers the detection piece 12. Further, in the third direction, the length of the key buckle 112 matches the length of the contact portion 113, so that when the key 11 does not generate the displacement, the gap between the contact portion 113 and the detection piece 12 is less than or equal to 1.5 mm; the third direction is the direction in which the key 11 points to the shell 14, i.e. Figure 35 the direction of the arrow in the middle. Among them, the structural features and technical details of the contact portion 113 are described above, and will not be described here.

[0184] In another embodiment, as shown in Figures 38-41As shown, the key 11 comprises a functional cover 1191 and a surface cover 1192, the surface cover 1192 at least partially covers the functional cover 1191 and is fixedly connected with the functional cover 1191; the functional cover 1191 is movably connected with the shell 14 and can directly or indirectly abut and trigger the detection piece 12. The surface cover 1192 can be understood as the outer cover of the key 11, covering the outer surface of the functional cover 1191, used for contacting with the user's fingers, improving the touch and appearance of the key 11, and the functional cover 1191 can be understood as the inner cover of the key 11, movably connected with the shell 14, used for realizing the movement of the key 11, triggering the detection piece 12 and other functions. Further, the surface cover 1192 and the functional cover 1191 are made of different materials. The surface cover 1192 is made of a material capable of improving the touch or appearance, such as metal, glass, AG frosted panel, etc., and the functional cover 1191 is made of hard plastic by injection molding. The fixed connection between the surface cover 1192 and the functional cover 1191 includes adhesion with adhesive or double-sided tape, clamping with buckle, clamping with slide, or other connection methods that can be implemented by those skilled in the art.

[0185] In some embodiments, as Figures 38-41 As shown, the reset part 15 is provided as a reed 153, which comprises a clamping part 1531 at the middle part and a deformation part 1532 at both ends of the clamping part 1531, the clamping part 1531 is clamped between the functional cover 1191 and the surface cover 1192, and the deformation part 1532 is bent towards the shell 14; when the key 11 generates the displacement, the deformation part 1532 is pressed by the shell 14 to elastically deform, and generates the reset force overcoming the elastic deformation. The clamping part 1531 clamped between the functional cover 1191 and the surface cover 1192 can be understood as that the surface cover 1192 is attached to the upper surface of the functional cover 1191, and the clamping part 1531 is arranged between the surface cover 1192 and the functional cover 1191, and the deformation part 1532 bent towards the shell 14 can be understood as that the deformation part 1532 at both ends of the reed 153 is inclined and bent towards the shell 14, and the functional cover 1191 is provided with a through hole at the position corresponding to the deformation part 1532, so that the deformation part 1532 passes through the through hole of the functional cover 1191 and abuts against the surface of the shell 14. The deformation part 1532 pressed by the shell 14 to elastically deform can be understood as that the reed 153 is made of elastic material, in this embodiment, the reed 153 is made of spring 1521 steel, which can be pressed to elastically deform and generate the reset force.

[0186] In the embodiment, the deformed portion 1532 of the spring 153 provides a reset force by being pressed and deformed, and the reset force has fewer influencing factors, so that the reset force is easy to control by structural design. The applicant changes the angle, thickness, width and length of the spring 153, and controls the reset force and the elastic force of the detection member 12 through calculation and simulation, so that when the key 11 moves to the first pressing position, the reaction force is F1, and when the key 11 moves from the first pressing position to the second pressing position, the reaction force jumps from F1 to F2; wherein F2 < F1 < 400 g; and the displacement S1 of the key 11 at the first pressing position and the displacement S2 of the key 11 at the second pressing position satisfy the relationship S2-S1≤2mm.

[0187] In a specific embodiment, as shown in Figure 38 and Figure 39 The functional cover 1191 is recessed with a clamping portion placing groove 1193 towards the clamping portion 1531, the shape of the clamping portion placing groove 1193 can contain the clamping portion 1531, and the depth of the clamping portion placing groove 1193 is greater than or equal to the thickness of the clamping portion 1531, so that when the surface cover 1192 is covered on the functional cover 1191, the surface cover 1192 is fitted with the functional cover 1191. The surface cover 1192 is fitted with the functional cover 1191, which can be understood as that when the surface cover 1192 is covered on the functional cover 1191, the surface cover 1192 is not lifted by the clamping portion 1531, and the lower surface of the surface cover 1192 can be fitted on the upper surface of the functional cover 1191.

[0188] Further, as shown in Figure 38 and Figure 39As shown, the clamping portion 1531 of the spring sheet 153 is provided with at least one positioning through hole 1533, and the functional cover 1191 is provided with a positioning boss 1194 at a position corresponding to the positioning through hole 1533. The size of the positioning boss 1194 is adapted to the positioning through hole 1533, so that the positioning boss 1194 is inserted into the positioning through hole 1533 to position the spring sheet 153. The positioning boss 1194 can be understood as a cylindrical boss protruding from the functional cover 1191 towards the surface cover 1192. The hole diameter of the positioning through hole 1533 is adapted to the outer diameter of the positioning boss 1194, so that the positioning through hole 1533 is sleeved on the positioning boss 1194, so that the spring sheet 153 is positioned in the horizontal direction by the key 11, and the positioning through hole 1533 and the positioning boss 1194 are in transition fit or small gap fit to improve the positioning accuracy. When there is only one positioning through hole 1533, only the cooperation between the positioning through hole 1533 and the positioning boss 1194 can limit the horizontal displacement degree of freedom of the spring sheet 153, but cannot limit the horizontal rotation degree of freedom of the spring sheet 153. The width of the clamping portion placement groove 1193 needs to be adapted to the width of the clamping portion 1531, so as to limit the horizontal rotation degree of freedom of the spring sheet 153. Since the spring sheet 153 is clamped between the surface cover 1192 and the functional cover 1191, its vertical displacement degree of freedom and rotation degree of freedom are limited.

[0189] Further, as shown in Figure 38 and Figure 39 , the positioning through hole 1533 is at least two, and is arranged in the long edge direction of the clamping portion 1531. When there are two or three positioning through holes 1533, the horizontal displacement and horizontal rotation degree of freedom of the spring sheet 153 can be limited by the cooperation of the two positioning through holes 1533 and the corresponding two positioning bosses 1194. Since the spring sheet 153 is clamped between the surface cover 1192 and the functional cover 1191, its vertical displacement degree of freedom and rotation degree of freedom are limited, and further all degrees of freedom of the spring sheet 153 are limited by the surface cover 1192 and the functional cover 1191.

[0190] Further, as shown in Figure 39 and Figure 40As shown, the end of the deformed part 1532 is attached to the upper surface of the shell 14, which is the side of the shell 14 facing the button 11. The end of the deformed part 1532 being attached to the upper surface of the shell 14 can be understood as the end of the deformed part 1532 being bent towards the horizontal direction so that the end of the deformed part 1532 is parallel to the upper surface of the shell 14. The beneficial effect is that since the restoring force provided by the spring 153 is generated by pressing the spring 153 after deformation, the end of the deformed part 1532 will slide outward relative to the shell 14 when the spring 153 is deformed. If the deformed part 1532 is inclined towards the shell 14, the end of the deformed part 1532 will scrape the upper surface of the shell 14 like a shovel, causing a large sliding resistance and a large pressing resistance of the button 11, and causing a large wear of the upper surface of the shell 14. Therefore, in this embodiment, the end of the deformed part 1532 is parallel to the upper surface of the shell 14, so that the end of the deformed part 1532 is attached to the upper surface of the shell 14, changing from line contact to surface contact, reducing the contact stress, reducing the sliding resistance of the end of the deformed part 1532, making the pressing of the button 11 smoother, and reducing the wear of the upper surface of the shell 14.

[0191] Further, the part of the shell 14 in contact with the spring 153 is provided with a wear-resistant part (not shown in the figure). When the button 11 moves, the end of the spring 153 presses against the wear-resistant part and moves relative to the wear-resistant part. The part of the shell 14 in contact with the spring 153 being provided with a wear-resistant part can be understood as the wear-resistant part being fixedly attached to the upper surface of the shell 14, including being bonded or clamped to the upper surface of the shell 14. The wear-resistant part is made of a metal sheet or a glass sheet or a wear-resistant plastic, and has a high wear resistance. When the button 11 moves, the button 11 compresses the spring 153, causing the deformed part 1532 to elastically deform, and the end of the deformed part 1532 to slide on the upper surface of the shell 14. Since the spring 153 is generally made of a hard metal, it can cause wear on the upper surface of the shell 14. Therefore, a wear-resistant part is provided at the part of the shell 14 in contact with the spring 153, and the spring 153 abuts against the surface of the wear-resistant part to prevent wear on the upper surface of the shell 14. At the same time, the surface of the wear-resistant part is smoother, which can further improve the smoothness of pressing the button 11.

[0192] Further, as shown in FIG. 8, the shell 14 is provided with a plurality of grooves 1412, and the spring 153 is arranged in the grooves 1412. Figure 41 and Figure 38As shown, the key 11 is provided with a plurality of key buckles 112 towards the shell 14, and the shell 14 is provided with a plurality of buckle sites 1415 corresponding to the key buckles 112, and the key buckles 112 are buckled into the buckle sites 1415, so that the limit position of the upward movement of the key 11 is limited. Further, one side of the key 11 towards the shell 14 is rectangular, and the key buckles 112 are four, distributed at the four corners of the rectangle and arranged towards the shell 14, and each key buckle 112 cooperates with each other to limit two degrees of freedom of displacement and one degree of freedom of rotation of the key 11 in the horizontal direction. The structural features and technical details of the key buckles 112 are described above, and will not be described here.

[0193] Further, as shown in Figure 40 The length of the key buckle 112 is adapted to the height of the bending of the deformation part 1532 towards the shell 14, so that when the key 11 does not displace, the end of the deformation part 1532 abuts against the shell 14. The length of the key buckle 112 being adapted to the height of the bending of the deformation part 1532 can be understood as follows: the deformation part 1532 of the spring piece 153 bends towards the shell 14, the clamping part 1531 of the spring piece 153 is fixed to the key 11, the end of the deformation part 1532 abuts against the upper surface of the shell 14, and the deformation part 1532 is clamped between the key 11 and the shell 14. The length of the key buckle 112 determines the distance between the key 11 and the shell 14, and the length of the key buckle 112 is controlled so that the distance between the key 11 and the shell 14 is less than the height of the bending of the deformation part 1532 of the spring piece 153 in the natural state, so that when the key 11 is installed on the shell 14, the deformation part 1532 of the spring piece 153 is in a state of being pressed and deformed. The beneficial effect is that the spring piece 153 has a pre-tightening force on the key 11, so that the key 11 is still supported by the spring piece 153 when it is not pressed, ensuring that the key 11 is in the upper limit position when it is not pressed, improving the flatness of the upper surface of each key 11, and improving the tightness of the key 11, and the key 11 will not be loose.

[0194] Further, as shown in Figure 41 The key 11 is provided with an abutting part 113 at a corresponding position of the detection piece 12, and when the key 11 displaces in response to the control force, the abutting part 113 directly or indirectly abuts against and triggers the detection piece 12. Further, in a third direction, the length of the key buckle 112 is adapted to the length of the abutting part 113, so that when the key 11 does not displace, the gap between the abutting part 113 and the detection piece 12 is less than or equal to 1.5 mm; the third direction is the direction of the key 11 pointing to the shell 14, that isFigure 40 The arrowed direction is the direction of the pivot connection. The structural features and technical details of the conflict portion 113 have been described above, and will not be described again here.

[0195] In some embodiments, as shown in Figure 43 The key 11 is pivotally connected to the shell 14 to limit three displacement degrees of freedom and two rotation degrees of freedom of the key 11. The key 11 makes a pivotal movement based on the shell 14 in response to the operation force, and triggers the detection piece 12 in the process of movement. The pivotal connection of the key 11 to the shell 14 can be understood as that the key 11 can rotate around a rotation axis of the shell 14, and the specific structure includes a shaft hole type pivotal connection, a clamping type pivotal connection, an abutting type pivotal connection, etc., which will be described below. The triggering of the detection piece 12 in the process of movement of the shell 14 can be understood as that the detection piece 12 is arranged at a trajectory point of the pivotal movement of the shell 14, so that the shell 14 abuts against the detection piece 12 in the pivotal movement, thereby triggering the detection piece 12.

[0196] In this embodiment, the key 11 is pivotally connected to the shell 14, and the key 11 corresponds to a lever, and the force relationship is relatively simple. Only the reset force needs to be calculated to obtain the corresponding reaction force. The reset force provided by the elastic arm is easy to control through structural design. The applicant can control the reaction force by controlling the reset force of the elastic arm. Through calculation and simulation, the reset force and the elastic force of the detection piece 12 are matched to make the reaction force F1 when the key 11 moves to the first pressing position, and the reaction force jumps from F1 to F2 when the key 11 moves from the first pressing position to the second pressing position. Wherein, F2 < F1 < 400g; and the displacement S1 of the key 11 at the first pressing position and the displacement S2 of the key 11 at the second pressing position satisfy the relationship: S2-S1≤2mm.

[0197] Further, as shown in Figure 42 and Figure 43 The middle position of the key 11 is pivotally connected to the shell 14, and the two ends of the key 11 can receive the operation force to generate the pivotal movement. Wherein, the shell 14 is provided with a detection piece 12 at the position of each end of the key 11, and the two ends of the key 11 can be pressed to trigger the corresponding detection piece 12. The advantage of this design is that the two ends of one key 11 correspond to two pressing functions, which can save the number of keys 11, so that the switch can realize more pressing functions in the limited key 11 panel space.

[0198] In another embodiment, one end of the key 11 is pivotally connected with the shell 14 (not shown in the figure), and the other end is capable of receiving the operation force to generate the pivotal movement. In this embodiment, the pivotal shaft is arranged at one end of the key 11, and the other end of the key 11 is pressed to make the key 11 pivotally move based on the pivotal shaft. The advantage of this design is that the area of the key 11 that is pressed is increased, and the key 11 is less likely to be accidentally pressed. In addition, the key 11 functions as a force lever, the power arm is lengthened, and the pressing feeling is improved by arranging the pivotal shaft at the end of the key 11.

[0199] Further, as shown in Figure 42 , the key 11 is provided with a contact portion 113 facing the detection member 12. The key 11 pivotally moves based on the shell 14 in response to the operation force, and drives the contact portion 113 to directly or indirectly press and trigger the detection member 12. The structural features and technical details of the contact portion 113 are described above, and will not be described here.

[0200] In some embodiments, as shown in Figure 42 and Figure 43 , a gap-fitted pivotal shaft and a pivot hole (not shown in the figure) are arranged between the key 11 and the shell 14. One of the pivotal shaft and the pivot hole is arranged at the key 11, and the other is arranged at the shell 14. The pivotal shaft is inserted into the pivot hole, so that the key 11 can pivotally move based on the pivotal shaft. In a specific embodiment, the two side edges of the key 11 are respectively provided with pivotal shafts, and the center axes of the two pivotal shafts are collinear. The inner side surface of the shell 14 is respectively provided with pivot holes at the corresponding positions of the two pivotal shafts. The pivot holes are gap-fitted with the pivotal shafts, the pivotal shafts can rotate in the pivot holes, and the lower ends of the pivotal shafts are provided with guide inclined surfaces, so that the pivotal shafts can be clamped into the pivot holes from top to bottom.

[0201] In some embodiments, as shown in Figure 42As shown, the first clamping jaw 1195 and the first rotating shaft 144 are arranged between the key 11 and the shell 14, one of which is arranged on the key 11 and the other of which is arranged on the shell 14; the first clamping jaw 1195 is clamped on the first rotating shaft 144 and is in clearance fit with the first rotating shaft 144, so that the first clamping jaw 1195 and the first rotating shaft 144 can rotate relatively, thereby enabling the key 11 to pivot based on the first rotating shaft 144. In a preferred embodiment, two first clamping jaws 1195 are arranged side by side in the middle of the key 11 towards the shell 14, and the first rotating shaft 144 is integrally formed on the shell 14 at the corresponding position of the first clamping jaw 1195. The first clamping jaw 1195 includes two first clamping arms 11951 arranged oppositely and not in contact, which are integrally formed on the key 11, and the two first clamping arms 11951 embrace each other to form a circular first clamping hole 11952 therebetween, the diameter of the first clamping hole 11952 being larger than the diameter of the first rotating shaft 144, so that the first clamping hole 11952 is in clearance fit with the first rotating shaft 144. The two first clamping arms 11951 are provided with clamping openings towards the first rotating shaft 144, and when the key 11 is installed, the clamping openings are pressed from top to bottom on the first rotating shaft 144, the first clamping arms 11951 are separated from each other under the action of their own elasticity, so that the first rotating shaft 144 is clamped into the first clamping hole 11952, and the first rotating shaft 144 can rotate in the first clamping hole 11952 to realize the pivotal connection of the key 11 and the shell 14.

[0202] Further, as Figure 42 and Figure 43As shown, the reset part 15 is arranged as at least a first elastic arm 154 extending out of the shell 14, which abuts at least part of the key 11 to provide the reset force for the key 11. Wherein, the abutting of the first elastic arm 154 to the lower surface of the key 11 can be understood as that the first elastic arm 154 extends and bends from the shell 14 towards the key 11, i.e. the first elastic arm 154 is raised to a certain height, and the upper surface of the end of the first elastic arm 154 abuts to the lower surface of the key 11. In a preferred embodiment, the middle part of the key 11 is pivotally connected with the shell 14, the two ends of the key 11 can be pressed to produce a pivotal movement and trigger the corresponding detection piece 12, and the shell 14 is provided with two first elastic arms 154 at the two ends of the key 11, the two first elastic arms 154 at the same end extend towards the two sides of the key 11 and abut to the lower surface of the key 11 respectively; wherein, the four first elastic arms 154 corresponding to the key 11 all abut to the lower surface of the key 11 and are raised to the same height, so that the key 11 is supported to a horizontal state, and the reset force received by the two ends of the key 11 is the same. Further, the lower surface of the key 11 is provided with a cylindrical abutting boss 1199 at the end of the first elastic arm 154, and the key 11 abuts to the first elastic arm 154 through the cylindrical abutting boss 1199 to prevent the first elastic arm 154 from being bent to a too high height and reducing the strength, and the cylindrical abutting boss 1199 compensates for a part of the height, so that the first elastic arm 154 is not raised to a too high height.

[0203] Further, the edge of the key 11 is provided with a first clamping hook (not shown in the figure) for clamping to the shell 14 to limit the limit position of the upward movement of the key 11. Wherein, the edge of the key 11 provided with the first clamping hook can be understood as that the two ends of the key 11 pivotally moving are respectively provided with the first clamping hook towards the side wall of the shell 14, and the side wall of the shell 14 is provided with a limiting step at the corresponding position of the first clamping hook, and the clamping of the first clamping hook to the shell 14 can be understood as that when the key 11 is in an unpressed state, the first clamping hook clamps to the edge of the limiting step to limit the limit position of the upward movement of the key 11. The function is that due to the manufacturing error of the first elastic arm 154, the elastic force and the upward raising height of the four first elastic arms 154 corresponding to the same key 11 are different, which causes the upper surface of the key 11 to be inclined and the upper surfaces of the keys 11 not to be in the same plane, affecting the appearance; therefore, the first clamping hook is arranged at the end of the key 11 to limit the limit position of the upward movement of the end of the key 11 and ensure the upper surface of the key 11 to be horizontal.

[0204] Further, the first elastic arm 154 is raised by a preset height towards the key 11, and the length of the first clamping hook matches the preset height, so that the first elastic arm 154 is in a state of being pressed by the key 11 when the key 11 does not displace. The length of the first clamping hook matching the preset height can be understood as that the first elastic arm 154 is arranged between the key 11 and the shell 14, and the length of the key clamping buckle 112 determines the spacing between the key 11 and the shell 14. The length of the key clamping buckle 112 is controlled so that the spacing between the key 11 and the shell 14 is less than the preset height of the first elastic arm 154, so that the first elastic arm 154 is in a state of being pressed and deformed when the key 11 is not pressed. Further, the part of the key 11 raised towards the end of the first elastic arm 154 is provided with an abutting protrusion for lifting the key 11 by a height, so that the key 11 has sufficient pressing allowance, and further presses and deforms the first elastic arm 154, so that the first elastic arm 154 is in a state of being pressed and deformed when the key 11 is not pressed. The beneficial effect is that the first elastic arm 154 has a pre-tightening force on the key 11, so that the key 11 is still supported by the first elastic arm 154 when not pressed, ensuring that the key 11 is in an upper limit position when not pressed, improving the flatness of the upper surface of each key 11, and improving the tightness of the key 11, without the situation of being loose and collapsed.

[0205] In another embodiment, the first elastic arm 154 is arranged at least partially between the key 11 and the detection member 12 (not shown in the figure), and the key 11 presses and triggers the detection member 12 through the first elastic arm 154. Here, the first elastic arm 154 arranged at least partially between the key 11 and the detection member 12 can be understood as that the first elastic arm 154 extends from the shell 14, and the end of the first elastic arm 154 is arranged above the detection member 12, the upper surface of the end of the first elastic arm 154 abuts against the lower surface of the key 11, and the key 11 indirectly triggers the detection member 12 by pressing the end of the first elastic arm 154, and the first elastic arm 154 provides a reset force for the key 11. Further, the end of the first elastic arm 154 is provided with a circular-arc-shaped protrusion towards the key 11, which is used to abut against the lower surface of the key 11. The circular-arc-shaped protrusion has the advantage that the contact between the circular-arc-shaped protrusion and the key 11 is point contact, and the contact point is close to the center of the circular-arc-shaped protrusion. Compared with surface contact, the contact position of point contact is easy to control, and accordingly, the position of the circular-arc-shaped protrusion abutting against the key 11 is relatively constant and does not change too much during the pressing process, so that the key 11 can vertically press the detection member 12 through the first elastic arm 154. The advantage of the embodiment that the first elastic arm 154 presses and triggers the detection member 12 is that the first elastic arm 154 is integrally formed with the shell 14, which ensures the relative position accuracy between the first elastic arm 154 and the shell 14, and since the detection member 12 is installed on the shell 14, the positioning accuracy between the first elastic arm 154 and the detection member 12 is guaranteed. Compared with the abutting portion 113 arranged on the key 11, the embodiment directly triggers the detection member 12 by using the first elastic arm 154, which avoids the accumulation of error size chain between the abutting portion 113 and the detection member 12, and is more easy to guarantee the positioning accuracy between the first elastic arm 154 and the detection member 12, thereby reducing the manufacturing precision requirement. Moreover, the key 11 and the detection member 12 do not need a positioning relationship, the positioning accuracy requirement of the key 11 is reduced, and the key 11 and the elastic limiting member 151 do not need a positioning structure, thereby reducing the manufacturing cost of the key 11 and the elastic limiting member 151.

[0206] In some embodiments, as Figure 44 and Figure 45As shown, the key 11 includes a key body 1196 and a connecting portion 1197, the key 11 is fixed with the shell 14 through the connecting portion 1197, the key body 1196 can be elastically deformed in response to the operation force and generate the reset force to overcome the deformation, and then the key body 1196 forms the reset portion 15; the key body 1196 is provided with a contact portion 113 facing the detection piece 12, when the operation force acts on the key 11, the key body 1196 is elastically deformed, and the contact portion 113 directly or indirectly presses and triggers the detection piece 12; when the operation force is removed, the deformation of the key body 1196 recovers, and the contact portion 113 returns to the original position. Wherein, the key body 1196 forming the reset portion 15 can be understood as that the key 11 is provided in a sheet structure with elasticity, can be elastically deformed and generate the reset force, one end is fixedly connected with the shell 14, and the other end can be pressed to make the key body 1196 elastically deform; or, the middle part of the key 11 is fixedly connected with the shell 14, and both ends can be pressed to make the key body 1196 elastically deform; the key body 1196 is the reset portion 15.

[0207] In the embodiment, the key body 1196 is elastically deformed to provide the reset force, the influencing factors of the reset force are single, the reset force is easy to be controlled through structural design, the applicant controls the reset force and the elastic force of the detection piece 12 through calculation simulation by changing the thickness and material of the key body 1196, so that when the key 11 moves to the first pressing position, the reaction force is F1, and when the key 11 moves from the first pressing position to the second pressing position, the reaction force jumps from F1 to F2; wherein, F2 < F1 < 400g; and the displacement S1 of the key 11 at the first pressing position and the displacement S2 at the second pressing position satisfy the relationship: S2-S1≤2mm.

[0208] Further, the connecting portion 1197 is fixedly connected with the shell 14 by screwing or riveting or clamping. The screwing can be understood as that the shell 14 is provided with a screw hole, and the connecting portion 1197 is fixed to the screw hole of the shell 14 by screwing. The riveting can be understood as that the connecting portion 1197 is fixed to the shell 14 by a rivet.

[0209] Further, as shown in Figure 44 the connecting portion 1197 is arranged at the middle position of the key 11, and the shell 14 is provided with the abutting portions 113 at two ends of the key 11 respectively. The two ends of the key 11 can respectively generate displacement in response to the operation force, thereby driving the abutting portions 113 to trigger the detection pieces 12. The two ends of the key 11 are respectively provided with the detection pieces 12 below the abutting portions 113. The middle position of the key 11 is fixedly connected with the shell 14 by the connecting portion 1197, and the two ends of the key 11 respectively extend downward to form the abutting portions 113 for triggering the detection pieces 12 below. The operation force can act on the two ends of the key 11 to make the key 11 elastically deform. The two ends of the key 11 generate the displacement under the action of the operation force, thereby driving the abutting portions 113 to trigger the detection pieces 12.

[0210] In another embodiment, the connecting portion 1197 is arranged at one end of the key 11 (not shown in the figure), and the shell 14 is provided with the abutting portions 113 at the other end of the key 11 away from the one end. The other end of the key 11 can generate displacement in response to the operation force, thereby driving the abutting portions 113 to trigger the detection pieces 12. The one end of the key 11 is fixedly connected with the shell 14 by the connecting portion 1197, and the other end of the key 11 extends downward to form the abutting portions 113 for triggering the detection pieces 12 below. The operation force acts on the other end of the key 11 to make the key 11 elastically deform. The other end of the key 11 generates displacement under the action of the operation force, thereby driving the abutting portions 113 to trigger the detection pieces 12.

[0211] In a preferred embodiment, as shown in Figure 44 and Figure 45As shown, the connecting portion 1197 is clamped to the shell 14; the connecting portion 1197 is provided with a first clamping portion 11971 facing the shell 14, and the shell 14 is provided with a second clamping portion 145 at a position corresponding to the first clamping portion 11971; the second clamping portion 145 is adapted in shape and size to the first clamping portion 11971, so that the first clamping portion 11971 is clamped to the second clamping portion 145, achieving fixed connection of the connecting portion 1197 and the shell 14. Further, the first clamping portion 11971 comprises at least one second clamping jaw 11972, and the second clamping portion 145 comprises at least one clamping shaft 1451; the second clamping jaw 11972 is clamped to the clamping shaft 1451 and is in interference fit with the clamping shaft 1451; the interference amount of the interference fit can prevent relative rotation between the second clamping jaw 11972 and the clamping shaft 1451 within a preset deformation range of the key 11, achieving fixed connection of the second clamping jaw 11972 and the clamping shaft 1451; wherein the preset deformation range of the key 11 refers to the deformation range of the key 11 within the pressing stroke. In a specific embodiment, the second clamping jaw 11972 corresponding to each key 11 has two, which are arranged in parallel and at intervals on the lower surface of the key 11; the second clamping jaw 11972 comprises two oppositely arranged second clamping jaw arms 11973 which are not in contact; the second clamping jaw arms 11973 are integrally formed on the key 11; the two second clamping jaw arms 11973 embrace each other to form a circular second clamping hole 11974 therebetween; the hole diameter of the second clamping hole 11974 is smaller than the shaft diameter of the clamping shaft 1451, so that the second clamping hole 11974 is in interference fit with the clamping shaft 1451. The two second clamping jaw arms 11973 are provided with guide openings facing the clamping shaft 1451; when the key 11 is installed, the guide openings are pressed downward on the clamping shaft 1451; the second clamping jaw arms 11973 are separated from each other under the action of their own elasticity, so that the clamping shaft 1451 is clamped into the second clamping hole 11974, achieving fixed connection of the connecting portion 1197 and the shell 14.

[0212] Further, as Figure 44 and Figure 45As shown, the shell 14 is provided with a second elastic arm 155 abutting against the key 11 for assisting the key 11 to reset. Wherein, the second elastic arm 155 abutting against the lower surface of the key 11 can be understood as that the second elastic arm 155 is curvedly extended by the shell 14 towards the key 11, that is, the second elastic arm 155 is upwarping to a certain height, and the upper surface of the end of the second elastic arm 155 abuts against the lower surface of the key 11. The second elastic arm 155 for assisting the key 11 to reset can be understood as that, since the key 11 is fixedly connected with the shell 14, the key 11 is pressed to be elastically deformed and to generate a reset force, at the same time, the second elastic arm 155 also generates a reset force to the key 11, and the purpose of the reset force of the second elastic arm 155 is to prevent the key 11 from losing the original elasticity after long-term use, so as to be unable to restore to the initial state, resulting in that the frequently used key 11 is unable to pop up after being collapsed downward, so that the detection piece 12 is unable to restore to the non-triggered state, affecting the normal use; and the infrequently used key 11 rebounds normally, resulting in that the upper surfaces of the keys 11 are not at the same height after long-term use. Therefore, the second elastic arm 155 is arranged for assisting the key 11 to restore to the initial position.

[0213] Further, as shown in the figure, Figure 44 The key 11 is provided with at least one second hook 1198 towards the shell 14, the second hook 1198 can be hooked to the shell 14, so that the upper surface height of each key 11 remains consistent; the upper surface of the key 11 is arranged as the surface of the key 11 away from the shell 14. The second hook 1198 can be hooked to the shell 14 can be understood as that the shell 14 is provided with a hook through hole 146 at the corresponding position of the second hook 1198, when the key 11 is in the state of not being pressed, the second hook 1198 extends into the hook through hole 146 and hooks the lower edge of the hook through hole 146 to limit the limit position of the key 11 upwardly popping up. In a preferred embodiment, the corresponding second hook 1198 of each key 11 has four, which are symmetrically located at the four corners of the key 11 to provide a limiting force for the key 11. The purpose is that, since there is a manufacturing error in the second elastic arm 155, the elastic force of the multiple second elastic arms 155 corresponding to the same key 11 and the height of the upward warping exist differences, resulting in that the upper surface of the key 11 is inclined, the upper surfaces of the keys 11 are not in the same plane, affecting the appearance; therefore, the key 11 limits the upward warping height through the second hook 1198, so that the upper surfaces of the keys 11 are horizontal. In another preferred embodiment, the second hook 1198 is arranged at the end of the key 11 (not shown in the figure) to limit the limit position of the end of the key 11 upwardly popping up, which can more accurately ensure that the upper surfaces of the keys 11 are horizontal.

[0214] Further, as shown in the figure, Figure 11As shown, the shell 14 includes an upper shell 141 and a lower shell 142, the upper shell 141 covers the lower shell 142, and is detachably connected with the lower shell 142; the upper shell 141 covers the lower shell 142 can be understood as, the upper shell 141 is recessed towards the lower shell 142 with a containing groove, which can accommodate at least part of the lower shell 142, when the upper shell 141 is buckled on the lower shell 142, at least part of the lower shell 142 is contained in the containing groove.

The movably connection between the key 11 and the upper shell 141 can be understood as that the key 11 is movably connected with the shell 14 as described above, and the specific connection structure is described in detail, and here the key 11 is movably connected with the upper shell 141 in the shell 14, and the connection structure is the same as that described above, which will not be described here. The intelligent switch further comprises a power panel 17 arranged in the lower shell 142 and used for connecting an external power line; at least one PCB board 16 electrically connected with the power panel 17 and provided with electric energy by the power panel 17; wherein the detection piece 12 is arranged on the PCB board 16 and electrically connected with the PCB board 16.

The detection piece 12 arranged on the PCB board 16 and electrically connected with the PCB board 16 can be understood as that the detection piece 12 is welded on the PCB board 16, or clamped on the PCB board 16 and abuts against the PCB board 16 by metal contact or abuts against the PCB board 16 by conductive spring and the like. In addition, in a preferred embodiment, the PCB board 16 is fixedly installed on the lower shell 142. In the daily use of the switch, when the number of switch keys 11 is too large, the user is easy to forget the corresponding relationship between the key 11 and the lamp; after the introduction of the intelligent switch, the switch can represent not only a single lamp, but also many scene modes, such as away mode and full-on mode, so that the function represented by the switch is more complex and the user memory is more difficult. Based on this, certain customer customization laser engraving technology is provided in the prior art, which can select to laser engrave the text or icon required by the customer on the switch. However, this scheme has difficulty in modifying the subsequent key 11 display content, so the upper shell 141 and the lower shell 142 are detachably connected, when the key 11 is damaged or the key 11 display content is desired to be replaced, the entire switch does not need to be replaced, only the upper shell 141 and the key 11 need to be replaced, and further, the key 11 and the upper shell 141 can be combined into a key 11 module and replaced as a whole.The PCB 16 and the power board 17 are arranged in the lower shell 142, and the electronic components of the switches connected with the PCB 16 and the power board 17 are also arranged in the lower shell 142, while the upper shell 141 is only provided with the button 11, so that when the upper shell 141 is replaced, the circuit part is not involved, and the cost of replacing the upper shell 141 can be reduced.

[0216] Further, as shown in Figure 8 and Figure 11 , the upper shell 141 and the lower shell 142 are connected by magnetic attraction, the upper shell 141 is provided with at least one magnet 1416, the lower shell 142 is provided with at least one magnetic attraction piece 1422, the magnetic attraction piece 1422 can be attracted by the magnet 1416, the upper shell 141 is adsorbed on the magnetic attraction piece 1422 by the magnet 1416, so as to realize the detachable connection of the upper shell 141 and the lower shell 142.

In a specific embodiment, at least one screw hole 14222 is formed in the sheet metal piece 14221, the diameter of the screw hole 14222 is matched with a screw, so that the screw can pass through the screw hole 14222 and fix the sheet metal piece 14221 on the mounting surface. Wherein, the screw fixing the sheet metal piece 14221 on the mounting surface can be understood as that the diameter of the screw cap 17221 is larger than the diameter of the screw hole 14222, the screw rod 17222 of the screw passes through the screw hole 14222 and is tightly fixed on the mounting surface, and the sheet metal piece 14221 is pressed and fixed on the mounting surface. The sheet metal piece 14221 has the beneficial effect that the sheet metal piece 14221 is generally provided in a wall switch, the wall switch needs to be installed on the wall through the sheet metal piece 14221, and the sheet metal piece 14221 of the present application is also used as the magnetic attraction piece 1422, so that the lower shell 142 does not need to be additionally provided with the magnetic attraction piece 1422 to realize the magnetic attraction connection with the upper shell 141, the structure is simplified, and the cost is saved.

[0217] The upper shell 141 is connected with the lower shell 142 by magnetic attraction, which is convenient for disassembling and replacing the upper shell 141. When the surface of the key 11 is worn or damaged, or the pattern or text on the surface of the key 11 needs to be replaced, the upper shell 141 and the key 11 can be replaced as a whole, so that a brand-new switch panel is obtained, and the display content is changed.

[0218] Further, as Figure 13 and Figure 14As shown, sheet metal part 14221 is snapped into lower housing 142. In one specific embodiment, a through hole matching the shape of the lower housing 142 is formed in the center of sheet metal part 14221. Sheet metal part 14221 is inserted from below the lower housing 142 and snapped into the outer surface of the lower housing 142. The through hole in the center of sheet metal part 14221 matching the shape of the lower housing 142 can be understood as the through hole in the center of sheet metal part 14221 fitting against the outer wall of the lower housing 142, so that the through hole of sheet metal part 14221 snaps into the outer wall of the lower housing 142. In one specific embodiment, the outer surface of the lower housing 142 includes at least a first outer side wall 14231, a second outer side wall 14232, a third outer side wall 14233, and a fourth outer side wall 14234 that surround each other, wherein the first outer side wall 14231 and the second outer side wall 14232 are disposed opposite to each other, and the third outer side wall 14233 and the fourth outer side wall 14234 are disposed opposite to each other. The first outer wall 14231 and the second outer wall 14232 are each provided with two sheet metal fasteners 14235. The first outer wall 14231 is provided with a first abutment 14236 between the two sheet metal fasteners 14235.

At the same time, the lower surface of the sheet metal part 14221 is respectively engaged with the sheet metal part buckle 14235 to restrict the downward displacement of the sheet metal part 14221. The first abutting part 14236, the second abutting part 14237, the third abutting part 14238, and the fourth abutting part 14239 cooperate with the horizontal height of the sheet metal part buckle 14235, so that the sheet metal part 14221 is locked into the lower housing 142. The aforementioned horizontal height coordination can be understood as follows: in the vertical direction, the distance between the first abutment 14236, the second abutment 14237, the third abutment 14238, and the fourth abutment 14239 and the sheet metal fastener 14235 is equal to the thickness of the sheet metal 14221, so that the sheet metal 14221 can be clamped and fixed.

[0219] Furthermore, such asFigure 8 、 Figure 11 and Figure 12 As shown in FIG. 13, FIG. 14, FIG. 15 and FIG. 16, the upper shell 141 is provided with at least one magnet mounting slot 14161 on the side of the upper shell 141 facing the key 11, the shape of the magnet mounting slot 14161 is adapted to the magnet 1416, the side wall of the magnet mounting slot 14161 is provided with a magnet limiting rib, the lower surface of the magnet 1416 is at least partially attached to the bottom wall of the magnet mounting slot 14161, and the magnet limiting rib clamps the side surface of the magnet 1416 to limit the magnet 1416. Wherein, the shape of the magnet mounting slot 14161 being adapted to the magnet 1416 can be understood as that the outer shape of the magnet mounting slot 14161 is slightly larger than the magnet 1416, the magnet mounting slot 14161 is open on the side of the key 11, the slot depth of the magnet mounting slot 14161 is greater than or equal to the height of the magnet 1416, so that after the magnet 1416 is put into the magnet mounting slot 14161 from the side of the key 11, the upper surface of the magnet 1416 is flush with the upper surface of the upper shell 141, or lower than the upper surface of the upper shell 141. The lower surface of the magnet 1416 is at least partially attached to the bottom wall of the magnet mounting slot 14161 (such as the lower surface of the magnet 1416 is flush with the bottom wall of the magnet mounting slot 14161, or the lower surface of the magnet 1416 is lower than the bottom wall of the magnet mounting slot 14161). Figure 21The bottom of the magnet mounting groove 14161 is at least partially attached to the surface of the magnetic member 1422 on the side of the magnetic member 1422, so as to reduce the distance between the magnet 1416 and the magnetic member 1422, thereby increasing the magnetic attraction between the magnet 1416 and the magnetic member 1422, and further increasing the magnetic attraction between the upper shell 141 and the lower shell 142, so as to prevent the upper shell 141 from falling off. The magnetic attraction between the magnet 1416 and the magnetic member 1422 can be understood as follows: the distance between the magnetic attraction limiting ribs matches the width of the magnet 1416, so that when the magnet 1416 is placed in the magnet mounting groove 14161, the magnetic attraction limiting ribs are in interference or transition fit with the magnet 1416, so that the magnet mounting groove 14161 clamps the magnet 1416 in the middle, so as to prevent the magnet 1416 from shaking in the magnet mounting groove 14161. The magnetic attraction limiting ribs have the following effects: first, without the magnetic attraction limiting ribs, only the side wall of the magnet mounting groove 14161 clamps the magnet 1416, and due to manufacturing errors, the size of the magnet mounting groove 14161 is too small, the magnet 1416 cannot be placed in, or the size of the magnet mounting groove 14161 is too large, the magnet 1416 cannot be clamped, and the magnet 1416 shakes in the magnet mounting groove 14161. The magnet 1416 is clamped by the magnetic attraction limiting ribs in the embodiment, which well avoids the influence of manufacturing errors. When the size is designed, the magnetic attraction limiting ribs are in interference fit with the magnet 1416, the interference amount is compensated by the deformation of the magnetic attraction limiting ribs, so as to eliminate the influence of manufacturing errors. The magnetic attraction limiting ribs are provided with a guide inclined surface at the entrance of the magnet mounting groove 14161, which helps the magnet 1416 to be placed in, and prevents the interference amount of the magnetic attraction limiting ribs from being too large and the magnet 1416 from being unable to be placed in. The second effect of the magnetic attraction limiting ribs is to ensure that the lower surface of the magnet 1416 is attached to the bottom wall of the magnet mounting groove 14161. Without the magnetic attraction limiting ribs, the side wall of the magnet mounting groove 14161 clamps the magnet 1416, and there is a round corner between the side wall and the bottom wall of the magnet mounting groove 14161. If the round corner is larger than the round corner of the magnet 1416, the lower surface of the magnet 1416 cannot be attached to the bottom wall of the magnet mounting groove 14161, and the attraction of the magnet 1416 to the magnetic member 1422 is weakened. The magnet 1416 is separated from the side wall of the magnet mounting groove 14161 by the magnetic attraction limiting ribs in the embodiment, so that the round corner of the magnet mounting groove 14161 has no effect on the magnet 1416, and the lower surface of the magnet 1416 can be attached to the bottom wall of the magnet mounting groove 14161.

[0220] Further, as Figure 8As shown, the magnet 1416 is cuboid, and there are four magnets 1416, two of which are located at each end of the upper shell 141, and the two magnets at the same end are arranged in a similar "one" shape. In an embodiment, the magnet 1416 is a long cuboid, and the magnet mounting groove 14161 is also a long cuboid. In other embodiments, the magnet 1416 can be a square or other shape. Since the magnet 1416 is located at the two ends of the upper shell 141, due to the principle of leverage, the magnetic attraction of the magnet 1416 holds the upper shell 141 during the pressing process of the key 11, and the upper shell 141 is not easy to be pressed. During the pressing process of the key 11, the upper shell 141 is not easy to be pressed. Since the two magnets 1416 at the same end are arranged in a similar "one" shape, the two magnets 1416 can cover the length of the upper shell 141 in the distribution direction of the magnet 1416 as much as possible, thereby improving the magnetic attraction between the magnet 1416 and the magnetic attraction member 1422.

[0221] Further, as shown in Figure 11 The outer side wall of the lower shell 142 is provided with a first positioning part 1424, and the inner side wall of the upper shell 141 is provided with a second positioning part 1418. When the upper shell 141 is covered on the lower shell 142, the second positioning part 1418 is sleeved on the first positioning part 1424, and the inner surface of the second positioning part 1418 at least partially abuts the outer surface of the first positioning part 1424, so that the upper shell 141 is positioned in the horizontal direction by the lower shell 142. In an embodiment, as shown in Figure 11 The inner side wall of the upper shell 141 includes two first inner side walls provided with the magnet mounting groove 14161, and two second inner side walls adjacent to the two first inner side walls, and the two second inner side walls are respectively provided with square protrusions 14181, and the square protrusions 14181 and the magnet mounting groove 14161 form the second positioning part 1418. The lower shell 142 is provided with positioning ribs 14241 on the first outer side wall 14231 and the second outer side wall 14232, and the positioning ribs 14241, the third abutting part 14238 and the fourth abutting part 14239 form the first positioning part 1424.

[0222] Further, as shown in Figure 11 The first positioning part 1424 is provided with a guide part 14242 towards the second positioning part 1418, and the guide part 14242 is provided as an inclined surface to facilitate the second positioning part 1418 to be sleeved into the first positioning part 1424.

[0223] Further, as shown in Figure 11As shown, the magnetic member 1422 is at least partially contained in the upper housing 141, and the lower surface of the magnetic member 1422 is flush with or protrudes from the lower end surface of the upper housing 141. In a specific embodiment, the distance between the surface of the magnetic member mounting groove 14161 toward the side of the magnetic member 1422 and the lower end surface of the upper housing 141 is less than or equal to the thickness of the magnetic member 1422, so that the lower surface of the magnetic member 1422 is flush with or protrudes from the lower end surface of the upper housing 141. The beneficial effect is that the magnetic member 1422 is a sheet metal member 14221, when the sheet metal member 14221 is screwed to the wall, the upper housing 141 will not abut the wall surface, causing the surface of the magnetic member mounting groove 14161 toward the sheet metal member 14221 to not fit the sheet metal member 14221, resulting in a decrease in magnetic force.

[0224] As shown in Figure 16 and Figure 15 , the power panel 17 is arranged in the specific connection structure of the lower housing 142, the inner wall of the lower housing 142 is provided with a power panel limiting rib 1425 for abutting the side surface of the power panel 17 to pre-position the power panel 17, the lower housing 142 is provided with a power panel positioning column 1429 from bottom to top, the power panel 17 is provided with a power panel positioning hole 174 at the corresponding position of the power panel positioning column 1429, the power panel positioning column 1429 is inserted into the power panel positioning hole 174 of the power panel 17 to position the power panel 17 in the horizontal direction, the lower housing 142 is provided with a power panel mounting portion, the power panel mounting portion is provided with a power panel bolt hole 14291, the power panel 17 is placed in the power panel mounting portion to be supported by the power panel mounting portion and fastened to the power panel bolt hole 14291 by the power panel 17.

[0225] Further, as shown in Figure 29 , the power panel 17 is provided with at least three wire posts 171 toward the bottom of the lower housing 142 for connecting the external power supply line and the controlled devices. Among them, the wire post 171 is electrically connected with the power panel 17, specifically, the wire post 171 is welded to the power panel 17, the wire post 171 is a metal conductive column extending from the power panel 17 toward the bottom of the lower housing 142 for connecting the live wire, the neutral wire and the controlled appliances. In this embodiment, the power panel 17 is welded with 6 wire posts 171, among which 2 wire posts 171 connect the live wire and the neutral wire, and the other 4 wire posts 171 are electrically connected with the live wire interfaces of 4 controlled devices, among which the 4 wire posts 171 connected with the controlled appliances are electrically connected with the power panel 17 through the relay 175, and the power panel 17 can control the power on and off of the 4 controlled devices through the relay 175, and the relay 175 is welded to the power panel 17.

[0226] Further, as shown inFigure 17 As shown, the lower housing 142 has multiple strip-shaped heat dissipation holes 1427 vertically arranged on its side surface. These holes are arranged side-by-side horizontally, extending upwards from the bottom of the lower housing 142 with a height less than 13mm. Because the power board 17 is equipped with an AC / DC conversion module 176 (such as...), Figure 29 As shown, the power board 17 includes relays 175 and other electronic components. Its functions include at least converting 220V AC to DC via the AC-DC conversion module 176 and controlling the power supply to and from various controlled devices via relays 175. Since the controlled devices' power comes from the power board 17, it generates considerable heat. To prevent overheating and damage to the circuitry, heat dissipation holes 1427 are provided on the side surface of the lower housing 142 from bottom to top. The positions of the heat dissipation holes 1427 correspond to the electronic components on the power board 17, aiding in heat dissipation. Furthermore, the upward extension height of the heat dissipation holes 1427 is less than 13mm to prevent users from seeing the internal electronic components through the holes, thus avoiding aesthetic concerns.

[0227] Furthermore, such as Figure 16 As shown, a wiring module 172 is placed at a corresponding position at the end of the terminal 171 in the lower housing 142. The wiring module 172 includes a wiring sleeve 1721 and a wiring bolt 1722. The wiring sleeve 1721 is sleeved on the terminal 171. The side wall of the wiring sleeve 1721 has a threaded hole adapted to the wiring bolt 1722. The wiring bolt 1722 can be screwed into the threaded hole and presses the terminal 171 against the inner wall of the wiring sleeve 1721. The connection bolt 1722 pressing the terminal 171 against the inner wall of the terminal sleeve 1721 can be understood as follows: the wire passes through the terminal sleeve 1721 and is placed between the terminal 171 and the inner wall of the terminal sleeve 1721. The connection bolt 1722 presses the terminal 171 against the inner wall of the terminal sleeve 1721, so that the terminal 171 and the terminal sleeve 1721 clamp and fix the wire, and the terminal 171 and the wire are in contact and conductive. It is worth noting that the width of the terminal sleeve 1721 in the axial direction of the connection bolt 1722 is at least three times the width of the terminal 171, so that there is a gap between the terminal sleeve 1721 and the terminal 171 to allow the wire to pass through. The terminal 171 has an arc-shaped plate structure. The side of the terminal sleeve 1721 that abuts against the terminal 171 is arc-shaped to fit the shape of the terminal 171, so that the terminal 171 and the terminal sleeve 1721 clamp the wire more tightly. At the same time, the side of the terminal 171 that abuts against the terminal sleeve 1721 is processed with horizontal stripes, so that the terminal 171 presses against the wire more firmly and prevents the wire from falling off.

[0228] Furthermore, such asFigure 16 and Figure 17 As shown, the wiring bolt 1722 includes an integrally formed nut 17221 and a screw 17222. Multiple first wiring through holes 14261 are formed on the side surface of the lower housing 142 at corresponding positions on the wiring module 172. The diameter of the first wiring through holes 14261 is larger than the diameter of the nut 17221, allowing the nut 17221 to be inserted into the first wiring through hole 14261 from inside the lower housing 142, with at least a portion exposed outside the lower housing 142. The phrase "at least a portion exposed outside the lower housing 142" can be understood as the end of the nut 17221 of the wiring bolt 1722, away from the screw 17222, being exposed outside the lower housing 142. The end of the nut 17221 is provided with a cross-shaped or flat-head screwdriver for easy tightening. The bottom surface of the lower housing 142 has multiple second wiring through holes 14262 at corresponding positions of the terminal 171. The wire is inserted through the second wiring through hole 14262 and passes through at least between the terminal 171 and the wiring sleeve 1721. When the wiring bolt 1722 is screwed toward the inside of the wiring sleeve 1721 until it abuts against the terminal 171, the continued screwing of the wiring bolt 1722 will cause the wiring sleeve 1721 to move to the left. The wire is clamped between the terminal 171 and the inner wall of the wiring sleeve 1721, so that the wire and the terminal 171 are pressed together to achieve conductivity.

[0229] Furthermore, such as Figure 17 and Figure 15 As shown, a stop portion 17223 is provided between the nut 17221 and the screw 17222. The stop portion 17223 is a ring-shaped structure arranged around the nut 17221. The outer diameter of the stop portion 17223 is larger than the diameter of the nut 17221 and the diameter of the first wiring through hole 14261, so that the stop portion 17223 cannot pass through the first wiring through hole 14261. The inner wall of the lower housing 142 with the first wiring through hole 14261 is designated as the first inner wall. The wire bolt 1722 is inserted downward from above the lower housing 142, and the nut 17221 is inserted into the first wiring through hole 14261. The first wiring through hole 14261 restricts the vertical displacement of the wire bolt 1722. The end of the screw 17222 away from the nut 17221 is abutted by the terminal post 171. The terminal post 171 and the first inner wall clamp the stop part 17223 and the screw 17222 in the middle to restrict the horizontal displacement of the wire bolt 1722.

[0230] Specifically, the wiring bolt 1722 is placed downward from above the lower shell 142, is pressed and pushed into the first wiring through hole 14261 by the wiring post 171, and is limited in vertical direction displacement by the first wiring through hole 14261. At the same time, the wiring post 171 and the inner wall of the lower shell 142 sandwich the wiring bolt 1722 in the middle to limit the horizontal direction displacement of the wiring bolt 1722. In a specific embodiment, the lower shell 142 is provided with a wiring module placement slot 14264 which is shaped to fit the wiring module 172 to limit the displacement of the wiring module 172 in the horizontal direction perpendicular to the axial direction of the wiring bolt 1722; the wiring module placement slot 14264 is provided with a bolt limiting rib 14265 from the upper part of the lower shell 142 towards the bottom of the lower shell 142, which limits the nut 17221 of the wiring bolt 1722 between the bolt limiting rib 14265 and the inner wall of the lower shell 142, thereby limiting the movement of the wiring bolt 1722 towards the inside of the lower shell 142; the side of the power board 17 is first positioned against the power board limiting rib 1425, is placed obliquely downward into the lower shell 142, so that the wiring post 171 is placed obliquely into the lower shell 142, and is then turned to a vertical state; when the wiring post 171 is turned from oblique to vertical, the wiring bolt 1722 is pressed and pushed into the first wiring through hole 14261 by the wiring post 171. The distance between the bolt limiting rib 14265 and the first inner wall of the lower shell 142 is greater than the height of the nut 17221 of the bolt of the wiring post 171, so that the bolt of the wiring post 171 can be placed downward from the upper part of the wiring module placement slot 14264 into the wiring module placement slot 14264. The wiring bolt 1722 is placed downward from above the lower shell 142, the nut 17221 is pushed into the first wiring through hole 14261, and the vertical direction displacement of the wiring bolt 1722 is limited by the first wiring through hole 14261; when the power board 17 is installed to the lower shell 142, the end of the screw rod 17222 away from the nut 17221 is pressed by the wiring post 171, so that the wiring post 171 and the first inner wall sandwich the stop portion 17223 of the wiring bolt 1722 and the screw rod 17222 in the middle to limit the horizontal direction displacement of the wiring bolt 1722.

[0231] Further, as shown in Figure 17 the distance between the part of the wiring post 171 abutting against the screw rod 17222 and the first inner wall is less than the total length of the wiring bolt 1722. So that, when the wiring module 172 is placed into the wiring module placement slot 14264 from above the lower shell 142, and the power board 17 is placed into the lower shell 142, the wiring post 171 stops against the tail end of the screw rod 17222 of the wiring bolt 1722, pushes the wiring bolt 1722 towards the first side wall, and the nut 17221 is pushed into the first wiring through hole 14261, so that the wiring module 172 is limited in vertical direction, preventing the wiring module 172 from moving up and down or tilting during transportation.

[0232] The distance between the bolt limiting rib 14265 and the first side wall is greater than the sum of the thickness of the nut 17221 of the wiring bolt 1722 and the stop portion 17223, so that the wiring bolt 1722 can be placed in the wiring module placement slot 14264 without interference. The first inner wall is provided with a stop limiting portion 14266 at the corresponding position of the stop portion 17223, which can limit the left displacement of the stop portion 17223, so that the wiring bolt 1722 is limited in the axial direction between the wiring post 171 and the blocking limiting portion, further limiting the displacement of the wiring bolt 1722 and preventing the wiring bolt 1722 from shaking. The height of the stop limiting portion 14266 protruding from the first inner wall is less than the height of the nut 17221 of the wiring bolt 1722, so that the nut 17221 can partially extend into the first wiring through hole 14261. The distance between the wiring post 171 and the blocking limiting portion is greater than the sum of the length of the screw rod 17222 of the wiring bolt 1722 and the thickness of the stop portion 17223, so that the wiring post 171 and the wiring bolt 1722 do not interfere with each other, and the wiring bolt 1722 will not bend the wiring post 171.

[0233] Further, as shown in Figure 19 The PCB 16 and the power board 17 are provided with a matching pin 161 and a pin 173, one of which is arranged on the PCB 16 and the other of which is arranged on the power board 17. The pin 161 is inserted into the pin 173 to realize the electrical connection between the PCB 16 and the power board 17. In a specific embodiment, the PCB 16 is arranged above the power board 17, the pin 161 is welded to the PCB 16 towards the power board 17, the pin 173 is welded to the power board 17 at the corresponding position of the pin 161, and the pin 161 is inserted into the pin 173 to realize the electrical connection between the PCB 16 and the power board 17.

[0234] In addition, the PCB 16 and the power board 17 can also be connected through metal contacts. Specifically, the PCB 16 is provided with a plurality of metal contacts (not shown in the figure) facing the power board 17. The power board 17 is provided with abutting columns with conductive ability at positions corresponding to the metal contacts. The abutting columns are electrically connected to the power board 17. The metal contacts abut against the abutting columns to realize the electrical connection between the PCB 16 and the power board 17. An elastic connecting member is arranged between the abutting columns and the power board 17. The abutting columns compress the elastic connecting member in response to the pressing force of the metal contacts. The elastic connecting member generates elastic deformation and a counterforce to overcome the elastic deformation, so that the abutting columns generate a compression displacement and a rebound force opposite to the compression displacement. The elastic connecting member provides elastic force to the abutting columns to ensure that the plurality of abutting columns can abut against the metal contacts and ensure good conduction.

[0235] Further, as shown in Figure 19 and Figure 20 , the PCB 16 is arranged in the lower shell 142. Two oppositely arranged side walls of the lower shell 142 are inwardly recessed to form two oppositely arranged U-shaped recesses 1428. The PCB 16 is provided with U-shaped notches 162 at positions opposite to the U-shaped recesses 1428. The positions and shapes of the U-shaped notches 162 are matched with the U-shaped recesses 1428 to position the PCB 16 in the horizontal direction. The positions and shapes of the U-shaped notches 162 matched with the U-shaped recesses 1428 can be understood as that the width of the U-shaped notches 162 is matched with the width of the U-shaped recesses 1428, and the distance between the two U-shaped notches 162 is matched with the distance between the two U-shaped recesses 1428, so that the outer wall of the U-shaped notches 162 abuts against the inner wall of the U-shaped recesses 1428, and the PCB 16 is limited in the horizontal direction by the lower shell 142.

[0236] The lower shell 142 is provided with a PCB 16 supporting portion for abutting against the lower surface of the PCB 16 to support the PCB 16. The upper end of the lower shell 142 is provided with a separation cover 18 extending downward to a PCB abutting portion 181 for abutting against the upper surface of the PCB 16 to limit the PCB 16 in the vertical direction. The PCB 16 supporting portion can be understood as a supporting rib extending from the inner side wall of the lower shell 142. The PCB abutting portion 181 is a pressing rib extending from the edge of the separation cover 18 toward the lower shell 142. In addition, as shown in Figure 13 , the sheet metal part 14221 is provided with screw holes 14222 at positions opposite to the two U-shaped recesses 1428 of the lower shell 142 to save the space occupied by the screw holes 14222.

[0237] In some embodiments, as shown in Figure 46 Fig. 7, the lower shell 142 is provided with a level 147 on the side facing the button 11, which is used to indicate the levelness of the installation of the smart switch on a mounting surface; the level 147 is provided as a cylindrical bubble level 147. In a specific embodiment, the isolation cover 18 is provided with a level 147 buckle, and the bubble level 147 is buckled and fixed to the isolation cover 18. When the user installs the switch on the mounting surface such as a wall, a cabinet or a table, he can see through the bubble level 147 whether the switch is installed obliquely, which is convenient for wall positioning and punching.

[0238] In another embodiment, as shown in Figures 47-50 Fig. 8, the upper shell 141 is provided with a PCB board mounting shell 148 facing the lower shell 142, and the upper shell 141 is provided on the PCB board mounting shell 148 to form a cavity, and the PCB board 16 is provided inside the cavity and fixedly connected with the PCB board mounting shell 148. Wherein, the upper shell 141 provided on the PCB board mounting shell 148 can be understood as that the PCB board mounting shell 148 is a groove-shaped structure with an open top, which is fixedly installed below the upper shell 141, and the upper shell 141 is provided on the top opening of the PCB board mounting shell 148. The PCB board 16 provided inside the cavity can be understood as that the PCB board 16 is fixedly installed inside the groove-shaped structure of the PCB board mounting shell 148 and is provided below the upper shell 141. The advantage of arranging the PCB board 16 below the upper shell 141 is that the error size chain between the detection piece 12 and the abutting portion 113 is shortened, so that the positioning accuracy between the abutting portion 113 and the detection piece 12 is easy to control; specifically, since the button 11 is connected with the upper shell 141, and the PCB board 16 is fixedly connected with the upper shell 141 through the PCB board mounting shell 148, the positioning reference of the button 11 and the PCB board 16 is the upper shell 141, and the positioning accuracy between them is high, and since the detection piece 12 is welded on the PCB board 16 and the abutting portion 113 is protruded on the button 11, the positioning error between the detection piece 12 and the abutting portion 113 is very small, the requirement for machining precision is reduced, and the manufacturing cost is reduced. Compared with the above embodiment in which the PCB board 16 is fixedly installed on the lower shell 142, the button 11 is arranged on the upper shell 141, and the lower shell 142 is detachably connected with the upper shell 141, the positioning reference between the detection piece 12 and the abutting portion 113 is converted for many times, which causes the accumulation of size chain, and the error of each size is accumulated to form a large error, which needs to control the machining precision of the parts to reduce the error, which increases the manufacturing cost. However, the problem does not exist when the PCB board 16 is installed on the upper shell 141, so that the size tolerance design is also simplified.

[0239] Further, asFigure 48 As shown in the figure, the inner shape of the PCB mounting shell 148 matches the shape of the PCB 16, the PCB mounting shell 148 is sleeved on the PCB 16 and positions the PCB 16 in the horizontal direction, and the PCB 16 is fixedly installed on the PCB mounting shell 148 by screws. Wherein, the inner shape of the PCB mounting shell 148 matching the shape of the PCB 16 can be understood as that the inner wall of the PCB mounting shell 148 at least partially abuts against the side wall of the PCB 16, so that the PCB mounting shell 148 positions the PCB 16 in the horizontal direction. Wherein, as shown in the figure, Figure 49 and Figure 48 As shown in the figure, in order to enable the PCB mounting shell 148 to be sleeved into the bottom shell 19, the outer shape of the PCB mounting shell 148 is consistent with the shape of the inner wall of the bottom shell 19, and since the two side surfaces of the bottom shell 19 are provided with bolt mounting hole positions, the two side surfaces of the bottom shell 19 are inwardly recessed, the two side walls of the PCB mounting shell 148 are inwardly recessed, and further, the two sides of the PCB 16 are also inwardly recessed. The PCB 16 is fixedly installed on the PCB mounting shell 148 by screws can be understood as that the PCB mounting shell 148 is provided with at least two threaded connecting columns protruding towards the PCB 16, which are supported on the lower surface of the PCB 16, the threaded connecting columns are processed with threads, and the PCB 16 is fixed on the threaded connecting columns by screwing, and in the embodiment, the PCB 16 is fixed on the threaded connecting columns by three screws.

Wherein, the upper shell 141 is recessed towards the light uniformizing sheet 1881 and is provided with a light uniformizing sheet mounting groove 1882 matched with the outer shape of the light uniformizing sheet 1881, when the upper shell 141 is covered on the PCB mounting shell 148, the light uniformizing sheet 1881 is limited by the light uniformizing sheet mounting groove 1882, and the lower surface of the light uniformizing sheet 1881 abuts against and is supported by the detection piece 12.

[0241] Further, as shown in the figure, Figure 48 and Figure 49As shown, the upper shell 141 is provided with a PCB shell positioning portion 1481 and a PCB shell buckle 148 towards the PCB plate mounting shell 148, and the PCB plate mounting shell 148 is provided with a second buckling position 1483 corresponding to the PCB shell buckle 1482, when the upper shell 141 is covered on the PCB plate mounting shell 148, the PCB shell positioning portion 1481 abuts against the outer side wall of the PCB mounting shell to position the PCB mounting shell; the PCB shell buckle 1482 buckles on the second buckling position 1483, so that the PCB mounting shell is fixedly installed on the upper shell 141.

[0242] Further, as shown in the drawings, Figure 49 As shown, the power supply board 17 and the PCB plate mounting shell 148 are provided with an isolation plate 149, and the isolation plate 149 is fixedly connected with the lower shell 142; the isolation plate 149 is provided with a pin passing hole 1491 corresponding to the pin 161, and the size of the pin passing hole 1491 is adapted to the size of the pin 161 and the pin 173, so that the pin 161 passes through the pin passing hole 1491 and is inserted into the pin 173. Wherein, the isolation plate 149 is fixedly connected with the lower shell 142 by screwing, and the isolation plate 149 is provided with a power supply board 17 abutting portion downwardly protruding, which is used for abutting and fixing the power supply board 17 on the lower shell 142. The function of the isolation plate 149 is to isolate the power supply board 17; because the PCB is connected with the upper shell 141, the PCB 16 and the power supply board 17 are electrically connected through the pin 161 and the pin 173, when the upper shell 141 is opened, the PCB 16 and the power supply board 17 are separated, in order to prevent the power supply board 17 from being exposed, which may cause the risk of electric shock to the user, the isolation plate 149 is arranged between the PCB 16 and the power supply board 17, which also meets the safety requirements.

[0243] Further, the outer side wall of the lower shell 142 is provided with a first positioning portion 1424, and the inner side wall of the upper shell 141 is provided with a second positioning portion 1418, when the upper shell 141 is covered on the lower shell 142, the second positioning portion 1418 is sleeved on the first positioning portion 1424, and the inner surface of the second positioning portion 1418 at least partially abuts against the outer surface of the first positioning portion 1424, so that the upper shell 141 is positioned in the horizontal direction by the lower shell 142. The detailed technical details of the first positioning portion 1424 and the second positioning portion 1418 are stated above, and will not be repeated here.

[0244] In some embodiments, as shown in the drawings, Figure 50As shown in the figure, the power board 17 is provided with an on-off switch 177, which can control the on-off of the AC power supply of the power board 17. The on-off switch 177 is a mechanical switch and is welded to the power board 17, which can cut off the AC power supply, can play the role of power-off protection when the switch is installed, can limit the use of the intelligent switch, and can also realize the power-off restart of the intelligent switch system.

[0245] Further, as shown in the figure, Figure 50 The PCB board 16 is provided with a first avoiding hole 1771 at the corresponding position of the on-off switch 177, and the surface of the lower shell 142 towards the side of the button 11 is provided with a second avoiding hole 1772 at the corresponding position of the on-off switch 177. The shapes of the first avoiding hole 1771 and the second avoiding hole 1772 are matched with the on-off switch 177, so that the on-off switch 177 at least partially protrudes from the lower shell 142 after passing through the first avoiding hole 1771 and the second avoiding hole 1772. The surface of the lower shell 142 towards the side of the button 11 can be understood as the upper surface of the lower shell 142, that is, the upper surface of the isolation cover 18. The on-off switch is arranged on the power board 17 and exposed on the isolation cover 18 after passing through the upper PCB board 16 and the isolation cover 18, which is convenient for pressing the on-off switch 177 after the upper shell 141 is removed, and controlling the on-off of the power board 17 and the PCB board 16 through the on-off switch 177.

[0246] Further, as shown in the figure, Figure 20 And Figure 21 As shown in the figure, the PCB board 16 is provided with at least one LED lamp 163 at the corresponding position of each button 11, and the light emitted by the LED lamp 163 is projected to the first surface of the button 11; the first surface is arranged as the side of the button 11 towards the shell 14. Among them, the first surface is the lower surface of the button 11. Each button 11 corresponds to multiple LED lamps 163, and the LED lamps 163 are arranged symmetrically around the detection piece 12 corresponding to the button 11. In a specific embodiment, the PCB board 16 is symmetrically welded with 4 or 6 LED lamps 163 on both sides of each detection piece 12.

[0247] Further, as shown in the figure, Figure 22As shown, the key 11 is provided with a light guide portion 114, light emitted by the LED lamp 163 is guided by the light guide portion 114 to a third surface of the key 11, which is arranged as a surface of the key 11 facing away from the shell 14; wherein the shape of the light guide portion 114 is arranged as a predetermined shape, so that the light guide portion 114 displays a predetermined pattern 1141 corresponding to the predetermined shape on the third surface of the key 11. The light guide portion 114 is integrally formed or fixedly connected to the key 11, and can guide light inside the key 11 to the outside of the key 11. Specifically, the key 11 is injection molded by using a light-transmitting material, and a non-light-transmitting coating layer 117 is coated on the outer surface of the key 11. The predetermined pattern 1141 is laser-engraved on the outer surface of the key 11, so that the non-light-transmitting coating layer 117 is removed by laser-engraving to form the light guide portion 114. Light of the LED is transmitted at the laser-engraved part of the key 11, and the predetermined pattern 1141 is displayed on the outer surface of the key 11. The predetermined pattern 1141 includes graphics or text. The laser-engraving scheme of the key 11 in cooperation with the upper shell 141 by magnetic attraction enables the user to freely select the predetermined pattern 1141 or the combination of multiple patterns, and the magnetic attraction structure can quickly switch the upper shell 141, thereby quickly switching the display content of the key 11.

[0248] Further, as shown in Figure 21 The PCB board 16 is arranged on the lower shell 142; the lower shell 142 includes a bottom shell 19 and a separation cover 18, the separation cover 18 is arranged on the bottom shell 19 and forms a containing cavity with the bottom shell 19, and the PCB board 16 is contained in the containing cavity. Specifically, the separation cover 18 is clamped to the bottom shell 19 by a separation cover buckle 186, at least one separation cover buckle 186 is arranged on the edge of the separation cover 18 and faces the bottom shell 19, and the separation cover 18 is clamped to the bottom shell 19 by the separation cover buckle 186; the bottom shell 19 is a slot-shaped shell 14 with an open upper end, the shape of the separation cover 18 is adapted to the shape of the open upper end of the bottom shell 19, and a clamping eave 182 extends outward from the edge of the separation cover 18, the separation cover 18 is arranged on the open upper end of the bottom shell 19, and the clamping eave 182 is attached to the upper end surface of the bottom shell 19. The separation cover 18 has an electrical separation function, because the power board 17 carries strong current, the power board 17 and the PCB board 16 cannot be exposed to the outside, so as to prevent the user from being at risk of electric shock after the upper shell 141 is opened.

[0249] Further, as shown in Figure 8 and Figure 11As shown, one side of the upper shell 141 facing the key 11 is provided with a first positive identification 14171 for indicating the positive direction of the upper shell 141; one side of the upper shell 141 facing the isolation cover 18 is provided with a second positive identification 14172, and one side of the isolation cover 18 facing the upper shell 141 is provided with a third positive identification 185, the second positive identification 14172 corresponds to the indication direction of the third positive identification 185, which is used to prevent the upper shell 141 from being installed on the lower shell 142 by mistake. The first positive identification 14171 can be an arrow, a word or a shape identification, which is used to prevent the key 11 from being installed by mistake.

[0250] As shown in Figure 21 and Figure 19 The isolation cover 18 is arranged between the key 11 and the PCB board 16, and the isolation cover 18 is provided with a light uniformizing cover 183 at the corresponding position of each key 11, the light uniformizing cover 183 covers the corresponding LED lamp 163 of each key 11, and the light emitted by the LED lamp 163 is projected to the key 11 after being uniformized by the light uniformizing cover 183. Among them, the isolation cover 18 is provided with a light uniformizing cover 183 at the corresponding position of each key 11, which can be understood as that the light uniformizing cover 183 is arranged below the center position of the key 11, and the light uniformizing cover 183 is located above the LED lamp 163, and the light emitted by the LED lamp 163 is projected to the key 11 after being uniformized by the light uniformizing cover 183. Specifically, the light uniformizing cover 183 extends four light uniformizing cover buckles 1831 towards the isolation plate, the isolation plate is provided with an isolation cover through hole 1832 matched with the light uniformizing cover 183 in shape, the side wall of the isolation cover through hole 1832 is provided with a light uniformizing cover buckling position 1833, and the four light uniformizing cover buckles 1831 are buckled on the light uniformizing cover buckling position 1833, so that the light uniformizing cover 183 is clamped on the isolation plate. In a preferred embodiment, the light uniformizing cover 183 is made of transparent material treated by atomization or opaque material such as white light-transmitting plastic, which has light-transmitting and light-uniformizing properties, and the light uniformizing cover 183 is made of PC plastic by injection molding.

[0251] Further, as shown in Figure 19 and Figure 21 The projection of the light uniformizing cover 183 on the third surface of the key 11 covers the predetermined pattern 1141. Among them, the third surface is the upper surface of the key 11, because the light uniformizing cover 183 is used to project the light emitted by the LED to the light guide part 114 after uniformizing, and then the light is transmitted by the light guide part 114, so that the light transmitted by the light guide part 114 is uniform in brightness, therefore the surface of the light uniformizing cover 183 facing the key 11 needs to cover the predetermined pattern 1141 of the light guide part 114, so that the brightness of the predetermined pattern 1141 is uniform.

[0252] Further, as shown in Figure 19 and Figure 21 , the surface of the light uniformizing cover 183 towards the side of the key 11 is rectangular, and the light uniformizing cover 183 is a rectangular bottom-opened cuboid cover. The surface of the light uniformizing cover 183 towards the side of the key 11 is the upper surface of the light uniformizing cover 183, and the surface of the light uniformizing cover 183 towards the side of the key 11 can be rectangular, square, circular or other shapes. In a preferred embodiment, the surface of the light uniformizing cover 183 towards the side of the key 11 is rectangular, and the light uniformizing cover 183 is a rectangular bottom-opened cuboid cover. The beneficial effect is that the predetermined pattern 1141 of the key 11 is generally text, including Chinese or English, and the text is generally horizontally arranged. The rectangular light uniformizing cover 183 is beneficial to cover all the text, so that the light transmission of the text is uniform. In some preferred embodiments, the smart switch has four keys 11, and the light uniformizing cover 183 also has four keys 11. The rectangular light uniformizing cover 183 has the function of preventing mistakes.

[0253] Further, as shown in Figure 19 and Figure 21 , the detection member 12 is covered by the light uniformizing cover 183, and the light uniformizing cover 183 is provided with a touch pressure through hole 1834 at the corresponding position of the detection member 12. The key 11 is provided with a contact portion 113 at the corresponding position of the detection member 12, the contact portion 113 passes through the touch pressure through hole 1834 and is placed above the detection member 12. When the key 11 generates the displacement in response to the operation force, the contact portion 113 presses and triggers the detection member 12. The light uniformizing cover 183 is provided with the touch pressure through hole 1834 at the corresponding position of the detection member 12, which means that the light uniformizing cover 183 is covered above the detection member 12, and the touch pressure through hole 1834 is provided directly above the detection member 12, so that the contact portion 113 is placed directly above the detection member 12, improving the reliability of triggering the detection member 12. As shown in Figure 9 and Figure 6 , the contact portion 113 is a column extending from the key 11 towards the detection member 12, and the cross section perpendicular to the extending direction is the first cross section. The size of the touch pressure through hole 1834 is greater than the size of the first cross section, and there is a gap between the contact portion 113 and the touch pressure through hole 1834. The first shape composed of two mutually intersecting and perpendicular rectangles can be understood as a shape similar to a "cross", which prevents the local glue thickness of the contact portion 113 from causing shrinkage during injection molding, affecting the triggering of the detection member 12. Since the movement of the key 11 when pressed is a composite movement of displacement and rotation, and the key 11 can be tilted towards multiple directions, a gap is set between the contact portion 113 and the touch pressure through hole 1834, which can prevent the contact portion 113 from interfering with the touch pressure through hole 1834 when the key 11 moves.

[0254] Further, as shown in Figure 19 and Figure 21 The light uniformity cover 183 is protruded from the isolation cover 18, and the height of the light uniformity cover 183 protruding from the isolation cover 18 is adapted to the distance between the isolation cover 18 and the PCB board 16, so that the distance between the surface of the light uniformity cover 183 towards the side of the key 11 and the PCB board 16 is greater than 3mm. Since the light uniformity cover 183 is provided with the touch pressure through hole 1834, in order to prevent the user from being electrically shocked by touching the touch pressure through hole 1834, the light uniformity cover 183 and the PCB board 16 need to have sufficient electrical clearance and creepage distance, so the height of the light uniformity cover 183 protruding from the isolation cover 18 is designed to be greater than 3mm, so as to ensure the safety of the user.

[0255] Further, as shown in Figure 8 and Figure 11 The upper shell 141 is provided with light uniformity cover light transmission through holes 1419 corresponding to the positions of the light uniformity cover 183, and the shape of the light uniformity cover light transmission through holes 1419 is matched with the light uniformity cover 183. When the upper shell 141 is covered on the lower shell 142, the light uniformity cover 183 is accommodated in the light uniformity cover light transmission through holes 1419. Specifically, the light uniformity cover 183 is a rectangle, and correspondingly, the light uniformity cover light transmission through holes 1419 are also rectangular through holes. The light uniformity cover light transmission through holes 1419 have two functions, first, they can transmit light, so that the light of the light uniformity cover 183 can be projected to the lower surface of the key 11, second, the light uniformity cover 183 is placed below the key 11 after passing through the light uniformity cover light transmission through holes 1419, which further shortens the distance between the light uniformity cover 183 and the key 11, and reduces the attenuation of light.

[0256] In a preferred embodiment, as shown in Figure 23 The number of the light uniformity cover 183 is one more than the number of the key 11, and correspondingly, the number of the light uniformity cover light transmission through holes 1419 is one more than the number of the key 11. Specifically, there are four keys 11 and five light uniformity covers 183, and correspondingly, there are also five light uniformity cover light transmission through holes 1419 which are arranged corresponding to the light uniformity covers 183. The use of five light uniformity covers 183 is conducive to switching the key 11 between single key and multiple keys, which will be described in detail below. Since the four keys 11 are symmetrically arranged, the four light uniformity covers 183 corresponding to the keys 11 are also symmetrically arranged, and it is difficult to distinguish the corresponding relationship between the light uniformity cover light transmission through holes 1419 and the light uniformity covers 183 when the upper shell 141 is installed. Therefore, the light uniformity covers 183 are arranged as five, which has the function of preventing mistakes, and can quickly find the corresponding relationship between the light uniformity cover light transmission through holes 1419 and the light uniformity covers 183, and then quickly install the upper shell 141. In other embodiments, the number of the light uniformity covers 183 is the same as the number of the keys 11, as shown in Figure 11As shown, the light uniformity cover 183 corresponds to the key 11 one by one, which can reduce the use of the light uniformity cover 183 and save costs.

[0257] In another embodiment, as Figures 51-54 shown, a waterproof light transmission piece 41 is arranged between the isolation cover 18 and the bottom shell 19, the waterproof light transmission piece 41 is sealingly connected with the bottom shell 19, and further forms a sealed cavity with the bottom shell 19, the sealed cavity contains the detection piece 12, the wireless communication module 13, the PCB board 16 and the LED lamp 163. Wherein, the waterproof light transmission piece 41 can be understood as a waterproof shell 14 made of soft materials such as silica gel and rubber, or made of plastic, which is sealingly connected with the bottom shell 19 to form a waterproof sealed cavity, and protects the electronic components from water and moisture, and also plays a role in electrical isolation.

[0258] Further, as Figure 52 and Figure 53 shown, the edge of the isolation cover 18 extends a sealing portion 187 towards the waterproof light transmission piece 41, the sealing portion 187 presses the edge of the waterproof light transmission piece 41 against the bottom shell 19 to achieve the sealing connection between the waterproof light transmission piece 41 and the bottom shell 19; wherein, the direction in which the isolation cover 18 points to the bottom of the bottom shell 19 is defined as the fifth direction, in the fifth direction, the gap between the sealing portion 187 and the bottom shell 19 is smaller than the thickness of the edge of the waterproof light transmission piece 41. Wherein, the sealing portion 187 can be understood as a pressing rib around the isolation cover 18, and the sealing portion 187 pressing the edge of the waterproof light transmission piece 41 against the bottom shell 19 can be understood as that the sealing portion 187 and the bottom shell 19 clamp the edge of the waterproof light transmission piece 41 in the middle to achieve the sealing connection between the waterproof light transmission piece 41 and the bottom shell 19. The gap between the sealing portion 187 and the bottom shell 19 is smaller than the thickness of the edge of the waterproof light transmission piece 41 can be understood as that the sealing portion 187 and the bottom shell 19 clamp the edge of the waterproof light transmission piece 41 in the middle with interference to improve the sealing performance. The fifth direction is the direction indicated by the arrow in Figure 52 , in this embodiment, the fifth direction is in the same direction as the third direction.

[0259] Further, as Figure 52As shown, the waterproof light-transmitting piece 41 is provided with a light-transmitting part 411 at the position corresponding to the LED lamp 163, and the light-transmitting part 411 is integrally formed or sealingly connected with the waterproof light-transmitting piece 41; the light-transmitting part 411 is arranged to be capable of transmitting light from one side to the other side. The light-transmitting part 411 is arranged between the key 11 and the LED lamp 163, and is made of a light-transmitting material, for transmitting the light emitted by the LED lamp 163 to the lower surface of the key 11. In addition, the light-transmitting part 411 has a light-uniformizing effect, and is capable of projecting the light emitted by the LED lamp 163 to the light guide part 114 of the key 11 after light-uniformizing, so that the light emitted by the text or pattern displayed on the upper surface of the key 11 is uniform. The sealing connection can be understood as a connection mode capable of sealing, including using sealing glue to paste or separate injection molding or other implementable connection modes. In a specific embodiment, the light-transmitting part 411 and the waterproof light-transmitting piece 41 are integrally injection molded by using white silica gel, so as to have the effects of light transmission and light uniformization.

[0260] Further, the light-transmitting part 411 is arranged between the light guide part 114 and the LED lamp 163, and the projection of the light-transmitting part 411 on the third surface of the key 11 covers the predetermined pattern 1141. The third surface is the upper surface of the key 11, and the light-transmitting part 411 projects the light emitted by the LED lamp 163 to the light guide part 114 of the key 11 after light-uniformizing, so that the predetermined pattern 1141 on the upper surface of the key 11 emits light. Therefore, the light-transmitting part 411 needs to cover the predetermined pattern 1141, so that each part of the predetermined pattern 1141 can emit light uniformly.

[0261] Further, as shown in Figure 52 and Figure 54 the light-transmitting part 411 is arranged between the key 11 and the detection piece 12, and the key 11 abuts against the light-transmitting part 411 and triggers the detection piece 12 through the light-transmitting part 411. The key 11 triggering the detection piece 12 through the light-transmitting part 411 can be understood as that the key 11 abuts against the upper surface of the light-transmitting part 411. Since the light-transmitting part 411 is arranged between the key 11 and the detection piece 12, when the key 11 is displaced in response to the operation force, the light-transmitting part 411 is pressed and displaced together with part of the key 11, and the light-transmitting part 411 is pressed and triggers the detection piece 12. The key 11 indirectly presses the detection piece 12 through the light-transmitting part 411, which has the advantage that since the light-transmitting part 411 is made of soft material, the pressing of the key 11 has a buffering effect, preventing the detection piece 12 from being damaged when the pressing force of the key 11 is large.

[0262] Further, as shown in Figure 53As shown, the isolation cover 18 is provided with an isolation cover through hole 1832 corresponding to the light transmission part 411, and the light transmission part 411 passes through the isolation cover through hole 1832 and is at least partially exposed on the upper surface of the isolation cover 18. Since the isolation cover 18 presses and fixes the waterproof light transmission part 41 against the bottom shell 19, the light transmission part 411 needs to pass through the isolation cover 18 to project the light of the LED lamp 163 to the lower surface of the button 11, so the isolation cover 18 is provided with the isolation cover through hole 1832 for the light transmission part 411 to pass through the isolation cover 18. The light transmission part 411 being at least partially exposed on the upper surface of the isolation cover 18 can be understood as that the light transmission part 411 can protrude from the upper surface of the isolation cover 18, or can be flush with or lower than the upper surface of the isolation cover 18, so that the abutting part 113 of the button 11 can contact the light transmission part 411. Since the button 11 presses and triggers the detection part 12 below through the light transmission part 411, in a preferred embodiment, the light transmission part 411 protrudes from the isolation cover 18, which facilitates the button 11 to press the light transmission part 411, and at the same time, the light transmission part 411 reserves space for the detection part 12 below.

[0263] Further, when the button 11 generates the displacement in response to the operation force, the button 11 presses the light transmission part 411 to generate elastic deformation, and when the operation force is removed, the light transmission part 411 restores to the initial state under the action of its own elasticity and drives the button 11 to restore to the initial position. Wherein, the light transmission part 411 driving the button 11 to restore to the initial position can be understood as that the light transmission part 411 has elasticity, can generate elastic deformation, and generates a restoring force to act on the button 11 to overcome the elastic deformation. Further, as shown, Figure 54 As shown, the button 11 is provided with an abutting part 113 protruding towards the light transmission part 411, and the abutting part 113 is spliced by four square pressure units, so that the abutting part 113 occupies most of the upper surface of the light transmission part 411, and the abutting part 113 uniformly presses the upper surface of the light transmission part 411 to prevent single-point pressure from causing the light transmission part 411 to slide and fail to trigger. In summary, the waterproof light transmission part 41 of the embodiment has at least four functions: 1. sealing and waterproofing to protect internal electronic components; 2. uniform light transmission to project the light emitted by the LED to the button 11 after uniform light transmission; 3. buffering the pressing force between the button 11 and the detection part 12 to prevent the detection part 12 from being damaged when the pressing force of the button 11 is large; 4. providing a restoring force to help the button 11 to restore to the initial position. Compared with the traditional waterproof part, the waterproof light transmission part 41 of the embodiment has multiple functions in one part, simplifies the internal structure of the switch, reduces the number of parts, simplifies the assembly steps, and reduces the manufacturing cost.

[0264] In another embodiment, as shown in Figure 55 and Figure 56As shown, the lower shell 142 is provided with at least one sounder 189, which is electrically connected with the PCB 16, for emitting sound in response to triggering of the detection member 12. Wherein, the sounder 189 emitting sound in response to triggering of the detection member 12 can be understood as using the sounder 189 as feedback of the key 11, prompting the user that the detection member 12 has been triggered by emitting sound. Generally, the paragraph feeling of pressing the detection member 12 itself is used as triggering feedback for the switch, and the spring of the detection member 12 jumps during pressing, and the user can judge whether the detection member 12 is easy to trigger from the hand feeling. However, this design has at least two defects: 1. When the detection member 12 is not sensitive or damaged, the user can feel the feedback of pressing the detection member 12, but the switch cannot detect the signal of the detection member 12, and cannot control the on-off of the controlled device, at this time, the feedback of the key 11 does not correspond to the work of the controlled device, which will cause the user to misjudge, and misjudge that the on-off of the controlled device is effective, when the controlled device is a delayed effective electric appliance, the user's misjudgment will be more obvious; 2. When the feedback of the detection member 12 is not obvious, or the user's touch feeling is not sensitive, the user will not feel the triggering of the detection member 12, which will bring inconvenience to the use. The embodiment uses the sounder 189 as the triggering feedback, and the sounder 189 is welded on the PCB 16, and the feedback is synchronized with the control of the controlled device, when the detection member 12 is damaged, pressing the detection member 12 will not trigger the feedback, and the user will not misjudge, and the sound size of the sounder 189 can be adjusted, and the user with insensitive sense organs can still feel the feedback of the key 11, which is convenient to use.

[0265] Further, as Figure 56As shown, the sound generator 189 is arranged as a speaker 1891, the lower housing 142 is provided with a speaker mounting position 1892, and the speaker 1891 is fixedly connected with the speaker mounting position 1892. The sound generator 189 can also be a buzzer or other sound-generating device. The speaker mounting position 1892 can be understood as a groove recessed on the surface of the lower housing 142, which is shaped to match the shape of the speaker 1891, so that when the speaker 1891 is mounted in the speaker mounting position 1892, the upper surface of the speaker 1891 does not protrude too much from the surface of the lower housing 142, and the upper housing 141 does not get lifted by the speaker 1891 when it is covered on the lower housing 142. Alternatively, the speaker mounting position 1892 can be arranged inside the lower housing 142, and the sound-generating surface of the speaker 1891 is placed into the speaker mounting position 1892 with the sound-generating surface facing the outside of the lower housing 142. The speaker 1891 can be arranged on the upper surface of the lower housing 142 or on the side surface of the lower housing 142. When the speaker 1891 is arranged on the upper surface of the lower housing 142, the upper housing 141 is covered on the lower housing 142 to hide the speaker 1891 under the upper housing 141, improving the appearance of the switch. The fixed connection between the speaker 1891 and the speaker mounting position 1892 includes clamping, screw connection, bonding or other implementable connection modes.

[0266] In a specific embodiment, as Figure 56As shown, the speaker mounting position 1892 is a cylindrical structure extending downward from the isolation cover 18. The inner diameter of the speaker mounting position 1892 is clearance-fitted with the speaker 1891. The speaker 1891 includes a speaker body 1893 and a speaker base 1894 disposed at the bottom of the speaker body 1893. The speaker base 1894 protrudes from the outer side wall of the speaker body 1893. The speaker 1891 is inserted from below the speaker mounting position 1892. The upper surface of the speaker base 1894 abuts against the lower surface of the speaker mounting position 1892. Adhesive is pasted on the upper surface of the speaker base 1894, or adhesive is pasted on the side surface of the speaker body 1893, so that the speaker 1891 is fixedly connected to the speaker mounting position 1892 by adhesive. The speaker base 1894 is electrically connected to a speaker wire 1895. A speaker connector 1896 is provided at the end of the speaker wire 1895. A speaker socket 1897, compatible with the speaker connector 1896, is soldered onto the PCB board 16. The speaker connector 1896 is inserted into the speaker socket 1897 to achieve an electrical connection between the speaker 1891 and the PCB board 16. When installing the isolation cover 18, the speaker 1891 is first fixed to the speaker mounting position 1892, then the speaker connector 1896 is inserted into the speaker socket 1897, and finally the isolation cover 18 is snapped onto the bottom shell 19. Furthermore, the isolation cover 18 has at least one sound-emitting hole 1898 at the corresponding position of the speaker 1891. The sound-emitting hole 1898 is a through hole penetrating the isolation cover 18, allowing sound emitted by the speaker 1891 to pass through the isolation cover 18.

[0267] In some embodiments, such as Figures 24-26 As shown, the button 11 can switch between single-button and multi-button configurations, and simultaneously, the corresponding configuration size changes according to the number of configurations, thereby realizing the switching of single-channel or multi-channel control functions. Specifically, as shown... Figure 24As shown, it is a single button 11 switch structure schematic diagram, at this time the button 11 size increases to cover the upper surface of the upper shell 141, the button buckle 112 is arranged at the four corners of the button 11, and the position of the button buckle 112 corresponds to the buckle site 1415 at the four corners of the upper shell 141. The four corners of the button 11 are respectively provided with button positioning pins 111, which correspond to the positions of the first positioning holes 1513, and the button positioning pins 111 are inserted into the first positioning holes 1513 for positioning. Among them, the button positioning pins 111 arranged at the four corners of the button 11 have the beneficial effect of maximizing the distance between the button positioning pins 111, so that the positioning is more accurate. It is worth noting that the detection piece 12 and the light uniform cover 183 of this embodiment are one, but the light uniform cover light transmission hole 1419 has five and is arranged side by side at both ends of the upper shell 141, one end of which is arranged with three light uniform cover light transmission holes 1419, and the light uniform cover light transmission hole 1419 at the middle position of the three corresponds to the detection piece 12 arranged below the light uniform cover 183. The button 11 extends the abutting portion 113 at the corresponding position of the detection piece 12, and when the button 11 is pressed, the abutting portion 113 triggers the detection piece 12. The isolation cover 18 is not provided with a light uniform cover buckle site 1833 and an isolation cover through hole 1832 at the corresponding position of the other light uniform cover light transmission hole 1419, further saving cost.

[0268] In addition, the button 11 is provided with at least one supporting portion 1122 away from the abutting portion 113 towards the shell 14, which is used for abutting to the shell 14, thereby supporting the end of the button 11 away from the abutting portion 113, preventing the end of the button 11 from being pressed down. The role of the supporting portion 1122 is to support the button 11, provide a fulcrum for the button 11, so that when the button 11 is pressed down as a whole, the button 11 pivots based on the supporting portion 1122, and the end close to the abutting portion 113 moves downward, so that the abutting portion 113 triggers the detection piece 12. At the same time, it can prevent the user from triggering the detection piece 12 when pressing the end of the button 11 away from the abutting portion 113, and the user still feels that the button 11 is pressed down, so that the user mistakenly thinks that the detection piece 12 has been triggered.

[0269] As Figure 25As shown, it is a structure schematic diagram of double-key 11 switch, at this time, the key 11 is rectangular, two keys 11 are arranged side by side, the key 11 is provided with the key buckle 112 at four corners, buckled in the buckling position 1415 of the middle cover, the key 11 is provided with the key positioning pin 111 at four corners respectively, corresponding to the position of the first positioning hole 1513, the key positioning pin 111 is inserted in the first positioning hole 1513 for positioning. The detection piece 12 and the light uniformizing cover 183 of this embodiment are both two, but the light uniformizing cover light transmission hole 1419 has five, the two ends of the key 11 face one side of the lower shell 142 each extend a contact part 113, the position of the contact part 113 corresponds to the position of the pressure touch hole 1834 of the light uniformizing cover 183, the contact part 113 is placed above the detection piece 12 after passing through the pressure touch hole 1834. As shown, Figure 26 As shown, it is a structure schematic diagram of three-key 11 switch, at this time, the key 11 includes a rectangular key 11 and two square keys 11, three keys 11 are arranged in the upper shell 141, each key 11 is provided with the key buckle 112 at four corners, buckled in the buckling position 1415 of the middle cover, the detection piece 12 and the light uniformizing cover 183 of this embodiment are both three, but the light uniformizing cover light transmission hole 1419 has five, the two ends of the rectangular key 11 face one side of the lower shell 142 each extend a contact part 113, the middle part of the two square keys 11 respectively extend a contact part 113, the position of each contact part 113 corresponds to the position of the pressure touch hole 1834 of the light uniformizing cover 183, the contact part 113 is placed above the detection piece 12 after passing through the pressure touch hole 1834. The isolation cover 18 is not provided with the light uniformizing cover buckling position 1833 and the isolation cover through hole 1832 at the corresponding position of the other light uniformizing cover light transmission hole 1419, further saving the cost. It is worth noting that, compared with the switch structure of single-key 11 and multi-key 11, only the structure of the key 11 and the isolation cover 18 is different, other parts are mutually used, such design saves the cost of grinding tool, design cost and manufacturing cost; and the user can flexibly switch single key and multi-key, with low replacement cost.

[0270] In addition, as shown, Figure 25 and Figure 26As shown, when the key 11 is long strip-shaped and the key 11 covers two uniform light cover light transmission holes 1419, at least one supporting part 1122 is provided on the end of the key 11 away from the abutting part 113 and protrudes towards the shell 14, so as to abut against the shell 14, thereby supporting the end of the key 11 away from the abutting part 113 and preventing the end of the key 11 from being pressed down. The supporting part 1122 serves to support the key 11 and provide a fulcrum for the key 11, so that when the key 11 is pressed down as a whole, the key 11 pivots based on the supporting part 1122, the end close to the abutting part 113 moves downward, and the abutting part 113 triggers the detection piece 12. At the same time, when the user presses the end of the key 11 away from the abutting part 113, the detection piece 12 cannot be triggered, but the user still feels that the key 11 is pressed down, which makes the user mistakenly think that the detection piece 12 has been triggered.

[0271] The embodiment provides a smart switch system including a cloud, a gateway, a smart terminal and at least one smart switch. The smart switch can be any switch device provided with a wireless communication module 13. The wireless communication module 13 can be at least one of a Bluetooth wireless communication module 13, a WIFI wireless communication module 13 and a radio frequency wireless communication module 13. In the embodiment, the smart switch is a wall switch. The smart terminal can be a mobile phone, a tablet computer, a computer, a smart car machine, a smart household appliance and the like. The smart terminal can interact with the cloud through a WIFI network (router) or through a Bluetooth gateway. The gateway can be any device capable of communicating with the cloud and the smart switch, such as a wall switch provided with a WIFI wireless communication module 13 and a radio frequency wireless communication module 13, or a network device dedicated to data interaction and processing, such as a WIFI gateway or a router. In the embodiment, the gateway is provided with a separate voice module and is a voice gateway. The cloud can be any device or combination of devices having data storage and processing capabilities and capable of interacting with the gateway, such as a server provided with a required program.

[0272] In a preferred embodiment, as shown in Figure 27 and Figure 28 The wall smart switch 101 further includes a display screen 164, which is electrically connected with the wireless communication module 13. The key 11 matches the position of the display screen 164.

[0273] The wireless communication module 13 is configured to:

[0274] control the display screen 164 to display a function identifier of the key 11. The function identifier is used to represent the current function of the key 11.

[0275] Directly or indirectly acquire the trigger signal of the key 11 being triggered, and control the trigger result corresponding to the current function to be executed;

[0276] The wireless communication module 13 is further configured to:

[0277] When the function of the key 11 changes, directly or indirectly receive and store an identification update instruction sent by the intelligent terminal, and update the function identification corresponding to the key 11 displayed on the display screen 164 based on the identification update instruction, so that the function identification can represent the current function of the key 11; the identification update instruction carries the current function information of the key 11.

[0278] When the number of switch keys 11 is too large, the user is easy to forget the corresponding relationship between the key 11 and the lamp; after the introduction of the intelligent switch, the switch represents not only a single lamp, but also many scene modes, such as the away mode and the full-on mode, so that the function represented by the switch is more complex and the user's memory is more difficult. Based on this, the prior art provides a certain customer customization laser engraving technology, which can select to laser engrave the text or icon required by the customer on the switch. However, this solution has difficulty in subsequent modification, and the customization service process is complex. On the other hand, although many smart home central control screens provide control of intelligent lighting in the whole house or scene mode keys 11 on the central control screen, the full-size touch screen is high in cost, and the complex interface and operation of the touch screen are very unfriendly to the old. Therefore, a simple, low-cost, and dynamically configurable switch that can display the name or icon of the function of the display key 11 is needed. The intelligent switch provided by the technical solution of the present application carries a display screen 164 that can display the function of the physical key 11 of the switch, and the function representation of each key 11 displayed on the display screen 164 can be dynamically configured. For the intelligent switch with many keys 11, the user can easily change the function representation of the corresponding area on the display screen 164 based on the current function of each key 11, so that the function of the key 11 of the intelligent switch can be changed and indicated at zero cost.

[0279] Further, directly or indirectly acquire the trigger signal of the key 11 being triggered, and control the trigger result corresponding to the current function to be executed; including:

[0280] Acquire the trigger signal of the key 11 being triggered, and determine the key value information of the triggered key 11 based on the trigger signal, and then match the target function in the stored function mapping table based on the key value information, and control the trigger result indicated by the target function to be executed; the key 11 function mapping table defines the trigger relationship between at least one key value information and at least one trigger result, which is directly or indirectly issued and stored in the local memory of the wireless communication module 13 by the user after being freely determined on the intelligent terminal.

[0281] In this embodiment, the smart switch can control the trigger result corresponding to the trigger signal to be executed based on the locally stored function mapping table, without being controlled based on the cloud or the gateway, thereby achieving the purpose of being able to control even when the network is disconnected.

[0282] Further, the trigger signal of the key 11 being triggered is directly or indirectly acquired, and the trigger result corresponding to the current function is controlled to be executed; further comprising:

[0283] The trigger signal of the key 11 being triggered is acquired, and the key value information of the key 11 being triggered is determined based on the trigger signal;

[0284] The key value information is uploaded to the cloud, so that the cloud matches a target function in a stored function mapping table based on the key value information; the function mapping table is defined by a user through a smart terminal and is pre-stored to the cloud; the key 11 function mapping table defines a trigger relationship between at least one key value information and at least one trigger result.

[0285] The trigger result above can be understood as at least one executable function of at least one controlled device. The function involved in the trigger result can include opening or closing of the device, and can also include switching of a specific function of the device, for example, playing specific music or video of a controlled entertainment device, and can also be, for example, closing a curtain of a curtain control device; in this embodiment, the smart switch is a wall switch with multiple relay 175 control channels, and the trigger result includes opening or closing of the relay 175 of at least one control channel of the smart switch.

[0286] In this embodiment, the smart switch uploads the trigger signal to the cloud, and then the cloud judges and issues a corresponding control instruction, which can achieve more diverse control requirements.

[0287] Further, in some embodiments, the current control instruction can also be a voice control instruction uploaded by the user through the gateway; further, the wireless communication module 13 is further used for:

[0288] According to the control instruction issued by the cloud received directly or indirectly, the trigger result indicated by the control instruction is controlled to be executed; wherein the control instruction is generated by the cloud based on a target function after analyzing a voice control information based on an analysis result in a stored function mapping table; the voice control information is generated by a gateway in response to external voice control information; the analysis result at least contains corresponding key value information; the function mapping table is defined by a user through a smart terminal and is pre-stored to the cloud; the key 11 function mapping table defines a trigger relationship between at least one key value information and at least one trigger result.

[0289] In this embodiment, voice control is introduced. A user can upload voice control information based on a voice gateway, and then the cloud issues control instructions based on analysis of the voice control information, thereby liberating the user's hands and achieving more intelligent linkage control.

[0290] Further, when the function of the key 11 changes, an identification update instruction sent by a smart terminal is directly or indirectly received and stored, and the function identification corresponding to the key 11 displayed on the display screen 164 is updated based on the identification update instruction; including:

[0291] An identification update instruction sent by a smart terminal is directly or indirectly received and stored, and the function identification corresponding to the key 11 displayed on the display screen 164 is updated based on the identification update instruction; the identification update instruction is also used to trigger the smart terminal to upload the identification update instruction to the cloud, so that the cloud updates the stored function mapping table according to the correspondence relationship information between the key value information and the function identification carried in the identification update instruction.

[0292] In this embodiment, when the function of a smart switch or a certain key 11 changes, the user will update the function mapping table stored in the cloud and the smart switch in real time through a smart terminal (such as a mobile phone), so that the key value information of each smart switch in the function mapping table and the corresponding function identification are in the changed correspondence relationship, to prevent the problem that the function of the key 11 changes and does not correspond to the actual control trigger result.

[0293] The trigger result above can be understood as at least one executable function of at least one controlled device. The function involved in the trigger result can include the opening or closing of the device, and can also include the switching of a specific function of the device, such as playing specific music or video of a certain controlled entertainment device, and can also be, for example, closing a certain curtain control device. In this embodiment, the smart switch is a wall switch with multiple relay 175 control channels, and the trigger result includes the opening or closing of the relay 175 of at least one control channel of the smart switch.

[0294] In this embodiment, the smart switch is a wall switch. If the wall switch has multiple keys 11, the key value information above can represent different keys 11 in the smart switch, and different keys 11 can correspond to different relay 175 channels in the wall switch. If the wall switch has only one key 11, the key value information can also represent the switch information of the smart switch, which can be, for example, the ID of the smart switch. The function identification can correspond to the switch information, or can correspond to the information of a certain key 11.

[0295] In a specific embodiment, asFigure 27 and Figure 28 As shown in the figure, the display screen 164 includes a wire harness 165, and the display screen 164 is electrically connected to the PCB 16 through the wire harness 165. The keys 11 are matched with the positions of the display screen 164, and the display screen 164 is configured to display the corresponding functions of the keys 11. In this embodiment, the display screen 164 transmits data through the wire harness 165. The wire harness 165 is provided with a wire harness connector 1651 at the end away from the display screen 164. The PCB 16 is welded with a wire harness connector 166, and the wire harness connector 1651 is clamped in the wire harness connector 166 to realize the electrical connection between the display screen 164 and the PCB 16. In another embodiment, the PCB 16 is provided with a data transmission contact (not shown in the figure), and the wire harness 165 is pasted to the data transmission contact by adhesive to realize the electrical connection between the display screen 164 and the PCB 16. Alternatively, the wire harness 165 is welded to the PCB 16 (not shown in the figure) to realize the electrical connection between the display screen 164 and the PCB 16. The keys 11 are matched with the positions of the display screen 164, which means that the position of the display screen 164 can be matched with the keys 11, so that the position displayed by the display screen 164 can correspond to the corresponding keys 11. For example, the keys 11 are arranged horizontally and side by side on the upper surface of the shell 14, and the screen is arranged horizontally at the end of the keys 11. The long side direction of the screen is the same as the arrangement direction of the keys 11, and the screen can display the corresponding functions of the keys 11 at the corresponding positions of the keys 11. Alternatively, as shown in the figure, the keys 11 are four, and two by two are arranged side by side on the upper surface of the shell 14. The four keys 11 are located at the four corners of the upper surface of the shell 14. The display screen 164 is rectangular and arranged at the intersection of the four keys 11. The screen is divided into four areas, and the four areas correspond to the corresponding positions of the four keys 11, respectively. Each area of the screen can display the function of the corresponding key 11. The wireless communication module 13 is welded to the PCB 16 to realize the electrical connection between the display screen 164 and the wireless communication module 13. The wireless communication module 13 controls the display content of the display screen 164 according to the functions of the keys 11.

[0296] Further, as Figure 27As shown, the lower shell 142 includes a bottom shell 19 and a isolation cover 18, the isolation cover 18 covers the bottom shell 19, and forms a containing cavity with the bottom shell 19, the PCB board 16 is contained inside the containing cavity; the center position of the isolation cover 18 protrudes a display screen mounting position 184 towards the key 11, the display screen mounting position 184 is a through channel structure, the display screen 164 is fixedly installed on the upper end surface of the display screen mounting position 184, and the flat cable 165 passes through the display screen mounting position 184 and is electrically connected with the PCB board 16. The display screen 164 fixedly installed on the display screen mounting position 184 is that the middle part of the isolation cover 18 extends upwards to form a first side part 1841, a second side part 1842, a third side part 1843 and a fourth side part 1844 which are mutually enclosed, so as to form the display screen mounting position 184, the display screen mounting position 184 is open at the upper end, the display screen 164 covers and is pasted on the upper surface of the display screen mounting position 184, and the flat cable 165 of the display screen 164 passes through the display screen mounting position 184 and is connected to the PCB board 16.

[0297] As shown in FIG. 27 and FIG. 28 , the key 11 is provided with a display screen avoiding position 115 at the corresponding position of the display screen 164, the display screen 164 is enclosed in the display screen avoiding position 115, and the upper surface of the display screen 164 is flush with the upper surface of the key 11. The key 11 is provided with a display screen avoiding position 115 at the corresponding position of the display screen 164, which can be understood as that the display screen avoiding position 115 is a through hole, each key 11 is arranged in the upper shell 141, each key 11 is provided with a through hole at the corresponding position of the display screen 164, so that the display screen 164 passes through, and there is a gap between the display screen avoiding position 115 and the display screen 164, so as to prevent the key 11 from interfering with the display screen 164 during movement. The upper surface of the display screen 164 is flush with the upper surface of the key 11, which can be understood as that the height of the display screen mounting position 184 cooperates with the height of the key 11, so that the upper surface of the display screen 164 and the upper surface of the key 11 are in the same plane, and the appearance is improved.

[0298] Further, as shown in FIG. 27 , the upper shell 141 is provided with a display screen 164 passing hole at the corresponding position of the display screen 164, the shape of the display screen 164 passing hole is matched with the display screen 164, and the display screen 164 is placed in the display screen avoiding position 115 after passing through the display screen 164 passing hole. Since the display screen mounting position 184 is protruded upwards from the isolation cover 18, the upper shell 141 above the isolation cover 18 needs to be provided with the display screen 164 passing hole, so that the display screen mounting position 184 passes through.

[0299] Further, as shown in FIG. 28As shown, the button 11 extends towards the upper housing 141 from the corresponding positions of the first side 1841 and the third side 1843 of the display mounting position 184, with the button latch 112 extending outwards. The first side 1841 and the third side 1843 are arranged opposite to each other. Specifically, taking the four-button 11 version of the switch structure as an example, each button 11 is provided with four button latches 112. The button latches 112 are provided at the three corners of each button 11 away from the display screen 164. Due to the display screen clearance 115, the corner closest to the display screen 164 has a rectangular notch. The button latches 112 are provided near the rectangular notch of the button 11, so that the four button latches 112 are located as close as possible to the corner of the button 11 to provide stable limiting for the button 11.

[0300] According to another aspect of the present invention, a wireless smart switch 102 is also provided. Unlike the wall smart switch 101 described above, the wireless smart switch 102 is battery-powered and communicatively connected to a receiver, indirectly controlling the operation of the controlled device through the receiver. In a specific embodiment, the receiver is the wall smart switch 101 described above. In use, the wireless smart switch 102 triggers the detection element 12 in response to the user's operation, thereby sending a wireless message to the receiver. The receiver controls the operation of the controlled device according to the content of the wireless message, thus realizing the indirect control of the controlled device by the wireless smart switch 102. The controlled device can be a traditional electrical appliance such as a light or fan, which can be controlled to turn on and off by controlling the power supply; or it can be a smart device such as an air conditioner, television, robot vacuum cleaner, or smart curtain motor, which is controlled by the receiver issuing control commands to the controlled device.

[0301] Specifically, such as FIG. 57 and FIG. 58 As shown, the wireless smart switch 102 provided by the present invention includes: a housing 14, at least one button 11, a detection element 12, a reset part 15, and a wireless communication module 13. The button 11 is disposed on the housing 14, and at least a portion of the button 11 can respond to a control force to undergo a pressing movement, thereby generating displacement, such that the button 11 passes through at least a first pressing position and a second pressing position in sequence, and generates a reaction force. The detection element 12 can be triggered based on the displacement and generates a first rebound force to resist the displacement. The reset part 15 is configured to support the button 11 to deform directly or indirectly in response to the pressing movement, and generate a reset force to overcome the deformation. The wireless communication module 13 is communicatively connected to the detection element 12 to receive a corresponding trigger signal and send wireless messages to the outside based on the trigger signal.

[0302] The detection member 12 and the reset part 15 are matched to make the reaction force F1 when the button 11 moves to the first pressing position, and the reaction force jumps from F1 to F2 when the button 11 moves from the first pressing position to the second pressing position, wherein F2 < F1 < 400 g; the displacement S1 of the button 11 at the first pressing position and the displacement S2 of the button 11 at the second pressing position satisfy the relationship S2-S1≤2 mm.

[0303] The wireless communication module 13 is electrically connected with the detection member 12, when the detection member 12 is triggered, a corresponding trigger signal is generated, when the wireless communication module 13 detects the trigger signal, a corresponding wireless message is sent. Other technical details and principles are described in detail above, and will not be repeated here.

[0304] As shown in FIG. 57 and FIG. 58 The wireless intelligent switch 102 provided by the application has many same parts with the wall intelligent switch 101, such as the button 11, the reset part 15, the structure of the upper shell 141 and the structure of the light uniform cover 183, and the technical details and principles are described in detail above, and will not be repeated here. The differences are as follows: 1, the wireless intelligent switch 102 does not have the power board 17 and the electronic elements related to the power board 17, and the PCB 16 is powered by a battery; 2, the structure of the bottom shell 19 of the wireless intelligent switch 102 is different from that of the wall intelligent switch 101, specifically including the connection structure of the PCB 16 and the bottom shell 19, the structure of the magnetic attraction member 1422, the connection structure of the magnetic attraction member 1422 and the bottom shell 19, and the bottom shell 19 does not have the heat dissipation hole 1427; 3, the isolation cover 18 is provided with a through hole for disassembling the battery, and the structure is different. The different technical features of the wireless intelligent switch 102 and the wall intelligent switch 101 will be described in detail below.

[0305] Firstly, the structure of the magnetic attraction member of the wireless intelligent switch 102 is different from that of the wall intelligent switch 101, specifically as shown in FIG. 58 and FIG. 59As shown in the drawings, in some embodiments, the lower shell 142 is provided with a magnetic member fixing portion 42 at a position corresponding to the magnet mounting groove 14161, and the magnetic member fixing portion 42 is fixedly connected with the magnetic member 1422. The magnetic member fixing portion 42 can be understood as a structure capable of fixing the magnetic member 1422, which is fixedly connected or integrally formed with the lower shell 142. The magnetic member 1422 and the magnetic member fixing portion 42 can be fixedly connected by clamping, bonding, clamping, screw fastening, and other implementable ways. The magnet 1416 is fixedly installed in the magnet mounting groove 14161 of the upper shell 141, and the structural details are described in detail above, which will not be described here. The upper shell 141 is attracted to the magnetic member 1422 of the lower shell 142 by the magnet 1416, so as to achieve the magnetic attraction type detachable connection of the upper shell 141 and the lower shell 142. The lower shell 142 is provided with a first positioning portion 1424, which cooperates with the second positioning portion 1418 of the upper shell 141 to position the upper shell 141 by the lower shell 142. The technical details are described in detail above, which will not be described here. In a specific embodiment, the magnet 1416 fixing portion corresponds to the position of the magnet 1416 described above. The lower shell 142 includes a bottom shell 19 and a separation cover 18 (the technical details are described in detail above), and the magnetic member fixing portion 42 has two portions located at the left and right ends of the bottom shell 19, so as to increase the stability of the magnetic attraction connection.

[0306] Further, as shown in the drawings, FIG. 58 and FIG. 59 the magnetic member fixing portion 42 is provided with a magnetic member through hole 421, and the shape of the magnetic member through hole 421 is adapted to the magnet mounting groove 14161, so that the lower surface of the magnet mounting groove 14161 is attached to the upper surface of the magnetic member 1422 after passing through the magnetic member through hole 421. The shape of the magnetic member through hole 421 is adapted to the magnet mounting groove 14161, which can be understood as that the magnetic member through hole 421 is slightly larger than the lower surface of the magnet mounting groove 14161, so that the magnet mounting groove 14161 can pass through the magnetic member through hole 421. The advantage of this design is that the distance between the magnet 1416 and the magnetic member 1422 is reduced, and the wireless intelligent switch 102 of the present application can be attached to a ferrous surface, thereby increasing the magnetic attraction force between the magnet 1416 and the magnetic member 1422, so that the magnet 1416 can attract the ferrous mounting surface through the magnetic member 1422, preventing the switch from falling due to too small magnetic attraction force. Further, as shown in the drawings, FIG. 57 and FIG. 59 the lower surface of the magnetic member fixing portion 42 is pasted with an anti-slip paste 43 at a position corresponding to the magnetic member 1422. The upper surface of the anti-slip paste 43 has adhesion, and the lower surface has anti-slip characteristics, which can prevent the magnetic member 1422 from falling out of the magnetic member fixing portion 42, and also has the effect of preventing sliding when the switch is attracted to a ferrous mounting surface.

[0307] In another embodiment, as shown in FIG. 60 The magnetic member fixing portion 42 is provided with a magnetic member through hole 421, and at least a portion of the upper surface of the magnetic member 1422 is flush with the upper surface of the magnetic member fixing portion 42 after passing through the magnetic member through hole 421. When the upper shell 141 is covered on the lower shell 142, the at least a portion of the upper surface of the magnetic member 1422 is attached to the lower surface of the magnet mounting groove 14161. Wherein, the at least a portion of the upper surface of the magnetic member 1422 flush with the upper surface of the magnetic member fixing portion 42 can be understood as, as shown in FIG. 60 The direction of the bottom shell 19 pointing to the key 11 is the upper direction, the shape of the magnetic member through hole 421 is consistent with the upper part of the magnetic member 1422, the upper surface of the upper part of the magnetic member 1422 is in the same plane with the upper surface of the magnetic member fixing portion 42 after passing through the magnetic member through hole 421, so that the lower surface of the magnet mounting groove 14161 can be attached to the magnetic member 1422 and the magnetic member fixing portion 42 at the same time, which can not only shorten the distance between the magnet 1416 and the magnetic member 1422 to enhance the magnetic attraction, but also can make the magnet mounting groove 14161 get the support of the magnetic member fixing portion 42, so that the upper shell 141 will not tilt when the key 11 is pressed. In other embodiments, the upper surface of the magnetic member 1422 can be slightly sunken in the upper surface of the magnetic member fixing portion 42 to ensure that the magnet mounting groove 14161 gets the support of the bottom shell 19.

[0308] Further, as shown in FIG. 60 The magnetic member 1422 includes an attachment portion 14223 and a base portion 14224 integrally formed with the attachment portion 14223, the attachment portion 14223 passes through the magnetic member through hole 421 and is attached to the lower surface of the magnet mounting groove 14161, and the size of the base portion 14224 is larger than that of the attachment portion 14223, so that a first step is formed between the attachment portion 14223 and the base portion 14224; the magnetic member through hole 421 includes a first through hole matched with the attachment portion 14223 and a second through hole matched with the base portion 14224, and the size of the second through hole is larger than that of the first through hole, so that a second step is formed between the first through hole and the second through hole, and the second step abuts against the first step to limit the vertical upward displacement of the magnetic member 1422. Wherein, the attachment portion 14223 is in interference fit with the first through hole, so that the attachment portion 14223 passes through the first through hole and is clamped in the first through hole.

[0309] Further, the magnetic member fixing portion 42 is provided as a downwardly open groove, and the magnetic member fixing portion 42 is in interference fit with the magnetic member 1422, so that the magnetic member 1422 is placed under the magnetic member fixing portion 42 and clamped in the magnetic member fixing portion 42. Further, a non-slip patch 43 (not shown in the figure) is pasted on the lower surface of the magnetic member fixing portion 42 at a position corresponding to the magnetic member 1422, the upper surface of which is adhesive and the lower surface of which has non-slip properties, which can prevent the magnetic member 1422 from falling out of the magnetic member fixing portion 42 and also has the effect of preventing slipping.

As shown in FIG. 62 the magnetic member protrusion 44 can be understood as follows: due to the thin thickness of the bottom shell 19, which is similar to the thickness of the magnetic member 1422, a groove is provided on the lower surface of the magnetic member fixing portion 42 for mounting and accommodating the magnetic member 1422, and correspondingly, the magnetic member protrusion 44 is provided above the magnetic member 1422 to enhance the wall thickness of the magnetic member fixing portion 42 above the magnetic member 1422 and increase the strength of the magnetic member fixing portion 42; in addition, since the projection area of the hollow through hole 14162 is greater than the projection area of the magnetic member protrusion 44, the magnetic member protrusion 44 can pass through the hollow through hole 14162, the thickness of the magnetic member protrusion 44 is consistent with the thickness of the bottom wall of the magnet mounting groove 14161, so that the lower surface of the magnet 1416 can be attached to the upper surface of the magnetic member protrusion 44.

[0311] In another embodiment, as shown in FIG. 63 and FIG. 64As shown, the magnetic member fixing portion 42 is provided with at least one magnetic member fixing through hole 422, and the magnetic member 1422 is provided with at least one magnetic member recessed portion 14225, the size of the magnetic member recessed portion 14225 is matched with the size of the magnetic member fixing through hole 422, so that the magnetic member recessed portion 14225 is arranged in the magnetic member fixing through hole 422, and the other part of the magnetic member 1422 is overlapped on the upper surface of the magnetic member fixing portion 42, and the magnetic member 1422 is fixedly connected with the magnetic member fixing portion 42 by adhesion; wherein, the size of the magnetic member recessed portion 14225 is matched with the size of the magnetic member fixing through hole 422 can be understood as that the size of the magnetic member fixing through hole 422 is greater than the size of the magnetic member recessed portion 14225, so that the magnetic member recessed portion 14225 can be sunken in the magnetic member fixing through hole 422, in a specific embodiment, the bottom shell 19 is provided with two magnetic member fixing through holes 422 at two ends respectively, and the bottom shell 19 is provided with one magnetic member 1422 at two ends respectively, each magnetic member 1422 includes two magnetic member recessed portions 14225 arranged in the magnetic member fixing through hole 422 respectively, and the other part of the magnetic member 1422 is overlapped on the upper surface of the magnetic member fixing portion 42, that is, the part of the lower surface of the magnetic member 1422 is attached to the part of the upper surface of the bottom shell 19, and is fixedly connected by adhesion.

[0312] As shown, FIG. 64 the depth of the magnetic member recessed portion 14225 is matched with the thickness of the magnetic member 1422, so that the upper surface of the magnetic member recessed portion 14225 is flush with the upper surface of the magnetic member fixing portion 42, the position of the magnetic member recessed portion 14225 corresponds to the position of the magnet mounting groove 14161, and the length of the magnetic member recessed portion 14225 is greater than the length of the lower surface of the magnet mounting groove 14161, so that the lower surface of the magnet mounting groove 14161 is attached to the upper surface of the magnetic member recessed portion 14225.

[0315] Further, the key 11 is provided with a first surface on the side facing the shell 14, and the first surface is provided with a light-transmitting sheet 1883 (not shown in the figure) on the corresponding position of the light guide portion 114, which is arranged as a rainbow film capable of reflecting natural light into colored light, and the projection of the light-transmitting sheet 1883 on the first surface covers the projection of the light guide portion 114 on the first surface.

[0333] Specifically, in order to further reduce the thickness of the lower shell 142, please refer to FIG. 77 In an embodiment of the present application, the elastic wall 221 is recessed towards the bottom wall of the battery accommodating cavity 22 by a predetermined depth, and the first avoiding hole 18e is in communication with the battery accommodating cavity 22, thereby reducing the height of the movable buckle 231 protruding from the lower shell 142, which is beneficial to the thin design of the wireless intelligent switch 102; at the same time, the thickness of the elastic wall 221 is reduced due to the recess, so that the elastic wall 221 is more easily deformed under stress, thereby facilitating the operation.

[0334] Specifically, please refer to FIG. 78 In some embodiments of the present application, one end of the first avoiding hole 18e is provided as a communication end in communication with the battery accommodating cavity 22; that is, the communication end is located between one end of the elastic wall 221 and the side wall of the battery accommodating cavity 22, so that during the movement of the movable buckle 231 close to or away from the battery accommodating cavity 22, the force of the side wall of the battery accommodating cavity 22 on the elastic wall 221 is reduced, and the elastic wall 221 is more easily deformed, thereby facilitating the operation.

[0335] Further, the position of the movable buckle 231 on the elastic wall 221 is not limited, but since the force of the side wall of the battery accommodating cavity 22 on the elastic wall 221 gradually decreases from the end of the elastic wall 221 away from the communication end to the end of the elastic wall 221 close to the communication end, that is, the end of the elastic wall 221 close to the communication end can move relative to the side wall of the battery accommodating cavity 22, therefore, please refer to FIG. 78In some embodiments of the present application, the movable buckle 231 is arranged close to the communication end. Compared with being arranged away from the communication end, the movable range of the movable buckle 231 arranged close to the communication end is larger, and the movable buckle 231 is more likely to move under force, so that the installation and removal of the button cell 211 are more convenient. More specifically, the movable buckle 231 is arranged at one end of the elastic wall 221 close to the communication end, so as to improve the installation and removal efficiency of the button cell 211.

[0336] Please refer to FIG. 77 and FIG. 78 In some embodiments of the present application, when the movable buckle 231 moves, the clamping part 2312 of the movable buckle 231 can rotate relative to the connecting part 2311 under force. Specifically, the movable buckle 231 is arranged as an elastic buckle. According to the material properties of the movable buckle 231, the clamping part 2312 can elastically deform and rotate relative to the connecting part 2311 under force. More specifically, the material of the movable buckle 231 is plastic or rubber, etc., which is low in cost and convenient to process.

[0337] Of course, in other embodiments of the present application, only the clamping part 2312 of the movable buckle 231 can rotate relative to the connecting part 2311, so as to realize that the clamping part 2312 is close to or away from the battery accommodating cavity 22. Specifically, the part of the battery accommodating cavity 22 away from the opening end surface of the bottom shell 19 is recessed to form an avoidance groove. The movable buckle 231 is arranged at the bottom wall of the avoidance groove, and the movable buckle 231 is arranged away from the side wall of the avoidance groove away from the battery accommodating cavity 22, so as to form a first avoidance space. The first avoidance space is used to move the clamping part 2312 when the clamping part 2312 of the movable buckle 231 is away from the battery accommodating cavity 22. The first avoidance space provides a rotating space for the clamping part 2312 of the movable buckle 231, so as to ensure that the clamping part 2312 can rotate in a sufficient space to avoid the button cell 211 during the installation or removal of the button cell 211, and does not interfere with the button cell 211, so as to ensure that the button cell 211 is successfully installed and removed. In addition, the movable buckle 231 is arranged in the avoidance groove, so that the movable buckle 231 is flush with or lower than or slightly higher than the opening end surface of the battery accommodating cavity 22. Compared with the movable buckle 231 arranged directly at the opening end surface of the battery accommodating cavity 22, space can be saved, which is conducive to the light and thin design of the wireless intelligent switch 102.

[0338] Specifically, based on the above-mentioned embodiment that the lower shell 142 comprises a bottom shell 19 and a partition cover 18, the partition cover 18 covers the bottom shell 19 and forms a containing cavity 191 with the bottom shell 19, and the PCB board 16 is contained in the containing cavity 191, the movable buckle 231 is arranged on the bottom shell 19 or the partition cover 18, and the arrangement position of the movable buckle 231 is determined according to the arrangement position of the battery containing cavity 22.

[0339] Specifically, when the battery containing cavity 22 is only formed in the partition cover 18, the partition cover 18 is provided with a first containing through hole 222, the battery containing cavity 22 comprises the first containing through hole 222, and the movable buckle 231 is arranged on the partition cover 18 or the PCB board 16; when the battery containing cavity 22 is only formed in the PCB board 16, the PCB board 16 is provided with a second containing through hole 223, the battery containing cavity 22 comprises the second containing through hole 223, and the movable buckle 231 is arranged on the bottom shell 19, the PCB board 16 or the partition cover 18; when a part of the battery containing cavity 22 is formed in the partition cover 18 and another part is formed in the PCB board 16, the partition cover 18 is provided with a first containing through hole 222, the PCB board 16 is provided with a second containing through hole 223, the first containing through hole 222 and the second containing through hole 223 are communicated, the battery containing cavity 22 comprises the first containing through hole 222 and the second containing through hole 223, and the movable buckle 231 is arranged on the bottom shell 19 or the partition cover 18.

[0340] More specifically, please refer to FIGS. 1-3 In an embodiment of the present application, in order to further reduce the thickness of the lower shell 142 and realize the light and thin design of the wireless intelligent switch 102, a part of the battery containing cavity 22 is formed in the partition cover 18 and another part is formed in the bottom shell 19, that is, the partition cover 18 is provided with a first containing through hole 222, the PCB board 16 is provided with a second containing through hole 223, the first containing through hole 222 and the second containing through hole 223 are communicated, the battery containing cavity 22 comprises the first containing through hole 222 and the second containing through hole 223, and the movable buckle 231 is arranged on the bottom shell 19 or the partition cover 18. For this, the volume of the movable buckle 231 is different according to the different arrangement positions of the movable buckle 231; and compared with the case that the movable buckle 231 is arranged on the bottom shell 19, when the movable buckle 231 is arranged on the partition cover 18, the length of the movable buckle 231 is arranged shorter, so that the movable buckle 231 is not easy to be broken when the clamping part 2312 of the movable buckle 231 rotates, and the movable buckle 231 occupies smaller space. More specifically, please refer to FIG. 57 and FIG. 77In an embodiment of the present application, the movable buckle 231 is arranged on the isolation cover 18 and on the sidewall of the first accommodating through hole 222, the movable buckle 231 is movable relative to the lower shell 142, and the buckling part 2312 of the movable buckle 231 is rotatable relative to the connecting part 2311, wherein the sidewall of the first accommodating through hole 222 comprises the elastic wall 221, and the elastic wall 221 is the bottom wall of the avoiding groove.

[0341] In order to further improve the mounting stability of the button cell 211, the battery fixing structure 23 further comprises a limiting buckle 232 arranged on the sidewall or the opening end of the battery accommodating cavity 22 and arranged opposite to the movable buckle 231, so as to limit the button cell 211 in the direction perpendicular to the bottom wall of the battery accommodating cavity 22. In this way, the button cell 211 is fixed by the limiting buckle 232 and the movable buckle 231, so as to prevent the button cell 211 from falling out of the battery accommodating cavity 22 during the movement of the wireless intelligent switch 102.

[0342] It should be noted that, in the present application, the number of the movable buckles 231 is not limited, which can be one, two, three or the like. For details, please refer to the description of the number of the movable buckles 231 in the above embodiments. FIGS. 1-3 In an embodiment of the present application, based on the above-mentioned embodiment that the battery fixing structure 23 further comprises a limiting buckle 232 arranged on the sidewall or the opening end of the battery accommodating cavity 22 and arranged opposite to the movable buckle 231, so as to limit the button cell 211 in the direction perpendicular to the bottom wall of the battery accommodating cavity 22, the number of the movable buckles 231 is one, which can ensure the mounting stability of the button cell 211 and the operator only needs to operate one movable buckle 231 to realize the mounting or dismounting of the button cell 211, which is simple and convenient.

[0343] Specifically, in order to facilitate the operation of the movable buckle 231, the movable buckle 231 further comprises a holding part 2313 arranged on the side of the connecting part 2311 away from the battery accommodating cavity 22 in the direction perpendicular to the bottom wall of the battery accommodating cavity 22, and a second guide inclined surface is arranged between the holding part 2313 and the buckling part 2312. The arrangement of the holding part 2313 greatly facilitates the operator to apply force to the movable buckle 231, and the arrangement of the second guide inclined surface has a guiding effect on the button cell 211, so that the button cell 211 can be directly slid into the battery accommodating cavity 22 along the second guide inclined surface, and the mounting of the button cell 211 is more simple and convenient.

[0344] Specifically, in order to make the installation of the button cell 211 stable, the gap between the button cell 211 and the battery accommodating cavity 22 is small, so that there is not enough space for the operator to operate, and the button cell 211 can be directly and quickly taken out from the battery accommodating cavity 22, thereby affecting the disassembly efficiency of the button cell 211. Therefore, in some embodiments of the present application, the battery accommodating cavity 22 is provided with an elastic member 24. The elastic member 24 has a natural state and a compressed state pressed by the button cell 211. When the buckling part 2312 of the movable buckle 231 is away from the button cell 211, the elastic member 24 recovers from the compressed state to the natural state and acts on the button cell 211 to pop out part of the button cell 211 from the battery accommodating cavity 22. In this way, by providing the elastic member 24, when the button cell 211 is not limited by the movable buckle 231, part of the button cell 211 is forced to pop out of the battery accommodating cavity 22 by the elastic force of the elastic member 24, thereby improving the convenience of taking out the button cell 211.

[0345] It should be noted that based on the above-mentioned embodiment of "the battery fixing structure 23 further comprises a limiting buckle 232, which is arranged on the side wall or the opening end of the battery accommodating cavity 22 and is arranged opposite to the movable buckle 231, so as to limit the button cell 211 in the direction perpendicular to the bottom wall of the battery accommodating cavity 22", the elastic member 24 is arranged close to the movable buckle 231. In this way, when the buckling part 2312 of the movable buckle 231 is away from the button cell 211, the force of the limiting buckle 232 acting on part of the button cell 211 close to the movable buckle 231 is small and less than the elastic force of the elastic member 24, so as to ensure that part of the button cell 211 is smoothly popped out of the battery accommodating cavity 22.

[0346] It should be further noted that the form of the elastic member 24 is not limited and can be a spring or the like.

[0347] Further, the power module 21 further comprises a battery spring, which comprises a positive spring 213 and a negative spring 212, the positive spring 213 and the negative spring 212 are electrically connected with the positive and negative poles of the button cell 211 respectively and are electrically connected with the PCB 16 respectively; the negative spring 212 is arranged on the bottom wall of the battery accommodating cavity 22, used to contact and conduct electricity with the bottom wall of the button cell 211, and the elastic member 24 comprises the negative spring 212; since the negative spring 212 is elastic and is arranged on the bottom wall of the battery accommodating cavity 22, the negative spring 212 not only has the function of electrically connecting the button cell 211 and the PCB 16, but also can provide a certain elastic force to the button cell 211 when the button cell 211 is disassembled, so that part of the button cell 211 is bounced out of the battery accommodating cavity 22, improving the convenience of taking out the button cell 211, that is, having the function of the elastic member 24, and further not needing to arrange another elastic member 24, thereby simplifying the structure, saving the internal space and reducing the production cost.

[0348] Specifically, the button cell 211 can also be taken out by using a tool, which is convenient for disassembly. Generally, in order to make the button cell 211 stable, the gap between the button cell 211 and the battery accommodating cavity 22 is small, and there is not enough space for the tool to extend into the battery accommodating cavity 22 to take out the button cell 211. Therefore, in some embodiments of the present application, a battery disassembly groove 18c is arranged on the lower shell 142, the battery disassembly groove 18c is communicated with the button cell 211 accommodating cavity and is arranged close to the movable buckle 231; when the buckle part 2312 of the movable buckle 231 is away from the battery accommodating cavity 22, that is, away from the button cell 211, part of the button cell 211 close to the movable buckle 231 is no longer fixed by the buckle part 2312, at this time, a disassembly tool can be used to abut against the button cell 211 by being inserted into the battery disassembly groove 18c, so as to apply force to the button cell 211 and pry out the part of the button cell 211 close to the movable buckle 231 from the battery accommodating cavity 22, thereby facilitating the taking out of the button cell 211; it should be noted that the type of the disassembly tool is not limited, as long as it can be inserted into the battery disassembly groove 18c to take out the button cell 211, and specifically, the disassembly tool can be a screwdriver or the like.

[0349] It should be noted that, based on the above-mentioned embodiment that "the lower shell 142 is provided with two compensation holes 18b in a direction perpendicular to the bottom wall of the battery accommodating cavity 22, the two compensation holes 18b are arranged on the two sides of the elastic wall 221, and each compensation hole 18b is in communication with the battery accommodating cavity 22, so that when the movable buckle 231 is forced away from the battery accommodating cavity 22, the side wall of each compensation hole 18b close to the elastic wall 221 elastically deforms towards the movable buckle 231 to compensate the elastic deformation of the part of the elastic wall 221 for connecting the movable buckle 231", when the size of the compensation hole 18b is matched with the dismounting tool, the compensation hole 18b can be the battery dismounting groove 18c, that is, the dismounting tool can be directly inserted into the compensation hole 18b to dismount the button cell 211.

[0350] Specifically, in order to improve the installation stability of the button cell 211, the side wall of the battery accommodating cavity 22 is matched with the outer peripheral wall of the button cell 211. In this way, the limiting effect of the side wall of the battery accommodating cavity 22 on the button cell 211 can be enhanced, and the installation stability of the button cell 211 can be improved.

[0352] It should be noted that the negative spring piece 212 and the positive spring piece 213 can be an integral structure or a split structure. Specifically, please refer to FIGS. 79-95 In some embodiments of the present application, the negative spring piece 212 and the positive spring piece 213 are both integral structures and are formed by cutting, stamping, bending and other processes of a base material sheet, thereby increasing the reliability of the battery spring piece and facilitating processing.

[0353] Furthermore, the negative electrode area of ​​the button cell 211 generally includes the bottom wall of the button cell 211. However, in this invention, the bottom wall of the button cell 211 is the side wall of the button cell 211 facing the bottom shell 19.
