[0002] With the explosive growth of electronic devices such as smartphones and tablets, electronic devices have gradually become one of the devices that people often use in their daily lives or work. Electronic devices are usually equipped with physical buttons, such as volume control buttons or power buttons. The electronic device includes a middle frame, and a mounting hole is provided on the middle frame, and the button is assembled in the mounting hole. The button is connected to the middle frame, and the middle frame has a limiting effect on the button, so that the button can be pressed or released normally and will not fall off the middle frame. The user can perform corresponding operations on the electronic device through the button, for example, by pressing the volume control button, the electronic device can turn up or down the volume, or by pressing the power button, the electronic device can lock the screen or light up the screen.

[0003] However, the buttons in the related art have problems of shaking and making abnormal noises. Summary of the invention

[0004] The embodiments of the present application provide a key and an electronic device, which can alleviate or solve the problem of keys shaking and making abnormal noises on electronic devices.

[0005] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, an embodiment of the present application provides a button for an electronic device, comprising: a pressing member, an adapter and a guide rod, wherein one end of the adapter is connected to the inner side surface of the pressing member, and the other end of the adapter is used to be connected to a switch assembly of the electronic device, one end of the guide rod is fixedly connected to the inner side surface of the pressing member, and elastic members are provided on at least two opposite sides of the outer periphery of the guide rod, and the elastic members on the opposite sides of the outer periphery of the guide rod are used to interference fit with a middle frame of the electronic device.

[0007] The key provided in the embodiment of the present application is provided with a guide rod, one end of which is fixedly connected to the inner side of the pressing member, and elastic members are provided at least on two opposite sides of the outer periphery of the guide rod, and the elastic members on the opposite sides of the outer periphery of the guide rod are used to have an interference fit with the middle frame of the electronic device, so that the key can be fixed on the middle frame in a static state, thereby alleviating or solving the problem of shaking and abnormal noise of the key. In addition, the key provided in the embodiment of the present application has a simple structure and is easy to implement.

[0008] In a possible implementation, there are multiple guide rods, the pressing member is in a strip shape, and the multiple guide rods are arranged at intervals along the length direction of the pressing member. In this way, the anti-shaking effect of the key on the electronic device can be further enhanced.

[0009] In a possible implementation, the cross section of the guide rod is elliptical, the pressing piece is strip-shaped, and the major axis of the ellipse extends in a direction parallel to the length direction of the pressing piece. In this way, the anti-shaking effect of the key on the electronic device can be further enhanced.

[0010] In a possible implementation, the cross section of the guide rod is rectangular, the pressing piece is strip-shaped, and the long side of the rectangle is parallel to the length direction of the pressing piece. In this way, the anti-shaking effect of the key on the electronic device can be further enhanced.

[0011] In a possible implementation, elastic members are provided at least on two opposite sides of the outer periphery of the adapter, and the elastic members on the two opposite sides of the outer periphery of the adapter are used to have an interference fit with the middle frame of the electronic device. In this way, the anti-shaking effect of the key on the electronic device can be further enhanced.

[0012] In a possible implementation manner, the elastic member disposed on the periphery of the adapter and / or the elastic member disposed on the periphery of the guide rod is annular.

[0013] In this way, corresponding to the annular elastic member, an assembly position that is adapted or partially adapted to the adapter or the guide rod can be opened on the middle frame of the electronic device, and the annular elastic member can increase the interference fit area between the elastic member and the middle frame, thereby further enhancing the anti-shake effect of the key on the electronic device.

[0015] The annular elastic member is assembled in the annular assembly groove. The annular assembly groove can fix the annular elastic member to prevent the elastic member from being separated from the adapter or the guide rod during the key pressing process. In addition, the annular assembly groove can facilitate the assembly of the elastic member. The annular elastic member only needs to be sleeved in the annular assembly groove, and the annular elastic member can be self-locked in the annular assembly groove through its own elastic force.

[0016] In a possible implementation, the pressing member has a first end and a second end away from the first end, and the inner side surfaces of the first end and the second end are both provided with buckle tongues, and when the key is in a non-pressed state in the electronic device, a side of the buckle tongue facing the pressing member abuts against a middle frame of the electronic device, thereby preventing the key from being separated from the key installation slot.

[0017] In a possible implementation manner, the orthographic projection of the buckle tongue on the first end on the pressing member exceeds the range of the pressing member, and the orthographic projection of the buckle tongue on the second end on the pressing member does not exceed the range of the pressing member.

[0018] Such arrangement can facilitate the installation of the key on the one hand, and can make the opening area of ​​the installation slot slightly larger than the area of ​​the pressing piece on the other hand, so as to avoid the installation slot being too large, improve the aesthetics, and reduce the possibility of the key shaking in the installation slot.

[0019] In a possible implementation, a clamping groove is provided on the inner side of the pressing member, and one end of the adapter is clamped in the clamping groove, thereby ensuring that the pressing member and the adapter do not move relative to each other and preventing the two from colliding with each other and generating abnormal noise.

[0020] In a possible implementation manner, the pressing member and the adapter are integrally formed.

[0021] In a possible implementation manner, the pressing member and the guide rod are integrally formed.

[0022] In a possible implementation, the guide rod is adapted to an assembly position for accommodating the guide rod provided on the electronic device. In this way, the guide rod can also serve as a guide for the key. Furthermore, when the elastic member sleeved on the outer periphery of the guide rod is annular, the elastic member can also have waterproof properties.

[0023] In a possible implementation manner, the guide rod is the adapter.

[0024] In a possible implementation, the elastic modulus of the pressing member is greater than the elastic modulus of the adapter member, so that the pressing feel during use can be improved.

[0025] In a possible implementation manner, the elastic member is a plastic member.

[0026] In the second aspect, an embodiment of the present application provides an electronic device, comprising: a button, a middle frame and a switch assembly as shown above, the middle frame having a accommodating space and a mounting groove, the mounting groove being arranged on the outer wall of the middle frame, the button being assembled in the mounting groove, a first through hole being arranged in the mounting groove, the mounting groove being connected with the accommodating space through the first through hole, the inner side surface of the button being arranged facing the accommodating space, a groove or a second through hole being arranged on the middle frame, the groove or the second through hole being used to accommodate a guide rod of the button, the switch assembly comprising: a conductive member and a circuit board, the conductive member being arranged facing an adapter member of the button, the adapter member being connected to the conductive member through the first through hole, the pressing member of the button being used to drive the adapter member to move toward the accommodating space, the adapter member triggering the conductive member so that the conductive member contacts and conducts with the circuit board.

[0027] The electronic device provided in the embodiment of the present application, by setting a guide rod in the key, one end of the guide rod is fixedly connected to the inner side of the pressing member, and elastic members are set at least on two opposite sides of the outer periphery of the guide rod, and the elastic members on the opposite sides of the outer periphery of the guide rod are used to have an interference fit with the middle frame of the electronic device, so that the key can be fixed on the middle frame in a static state, thereby alleviating or solving the problem of shaking and abnormal sound of the key. In addition, the key structure provided in the embodiment of the present application is simple, and the implementation method is convenient and easy.

[0077] The material of the middle frame 121 may include, but is not limited to, aluminum alloy or plastic. The middle frame 121 may include a left side frame, a top frame, a right side frame, a bottom frame and a bottom plate, and the left side frame, the top frame, the right side frame and the bottom frame are connected in sequence to form an annular frame. The bottom plate is placed in the annular frame and connected to the annular frame, and the bottom plate is used to install the necessary electronic components of the electronic device 100. The middle frame 121 has an outer wall and an inner wall arranged opposite to each other. The outer wall of the middle frame 121 refers to the surface of the left side frame, the top frame, the right side frame and the bottom frame facing away from the accommodation space 121a. When the electronic device 100 is observed from the outside, the outer wall of the middle frame 121 is in a visible state. The inner wall of the middle frame 121 refers to the surface of the left side frame, the top frame, the right side frame and the bottom frame facing the accommodation space 121a. When the electronic device 100 is observed from the outside, the inner wall of the middle frame 121 is in an invisible state.

[0078] Figure 3 This is a schematic diagram of the structure of the switch assembly 130 provided in an embodiment of the present application, refer to Figure 3 As shown, the electronic device 100 further includes a switch assembly 130. The switch assembly 130 includes a conductive member 131 and a circuit board 132. The conductive member 131 is disposed on the circuit board 132. When the conductive member 131 is triggered, the conductive member 131 can contact and conduct with the circuit board 132. Figure 4 This is a partial structural diagram of an electronic device 100 provided in an embodiment of the present application, refer to Figure 4 As shown, the electronic device 100 provided in the embodiment of the present application further includes a button 200. Figure 4 The partial structure of the middle button 200 is enlarged to form Figure 5 , Figure 5 This is a partial structural diagram of a key 200 of an electronic device 100 provided in an embodiment of the present application, with reference to Figure 5 Combined with Figure 3 and Figure 4 As shown, the middle frame 121 has a mounting groove 121b. The mounting groove 121b is provided on the outer wall of the middle frame 121. A first through hole 121c is provided in the mounting groove 121b, and the mounting groove 121b is connected to the accommodating space 121a through the first through hole 121c. The button 200 is assembled in the mounting groove 121b, the button 200 is connected to the middle frame 121, and the inner side surface of the button 200 is arranged facing the accommodating space 121a. The switch assembly 130 can be embedded in the frame of the middle frame 121, or it can be arranged in the accommodating space 121a. The conductive member 131 is arranged facing the mounting groove 121b of the middle frame 121. The button 200 is connected to the conductive member 131.

[0079] When the button 200 is pressed, the button 200 can trigger the conductive member 131 so that the conductive member 131 is in contact with the circuit board 132 and is connected, thereby realizing the corresponding function of the electronic device 100. Exemplarily, the conductive member 131 can be an elastomer 140. When the button 200 is pressed, the button 200 moves toward the inside of the electronic device 100, and the button 200 can apply a force to the conductive member 131 so that the conductive member 131 undergoes elastic deformation and is in contact with the circuit board 132 and is connected. When the force of the button 200 disappears, under the action of the elastic restoring force of the conductive member 131 itself, the conductive member 131 is separated from the circuit board 132, and the conductive member 131 can drive the button 200 to move toward the outside of the electronic device 100, so that the button 200 and the conductive member 131 move to the initial position, which is convenient for pressing again. Exemplarily, the conductive member 131 can be, but is not limited to, a metal spring.

[0080] Figure 6 A side view of an electronic device 100 provided in an embodiment of the present application is shown in FIG. Figure 7 for Figure 6 The cross-sectional structure diagram of the electronic device 100 along the cutting line AA, Figure 8 for Figure 7 The enlarged structural diagram of the middle B part, Fig. 9 This is a schematic diagram of the structure of a key 200 provided in an embodiment of the present application, refer to Figure 8 and Fig. 9 As shown, the button 200 provided in the embodiment of the present application includes a pressing member 210 and a conversion member 220 .

[0081] Specifically, after the button 200 is assembled in the mounting groove 121b of the middle frame 121, the outer side of the pressing member 210 faces the outside of the electronic device 100, so that it is in a visible state, so that the user can press the pressing member 210. The inner side of the pressing member 210 is arranged to face the accommodating space 121a of the electronic device 100. One end of the adapter 220 is connected to the inner side of the pressing member 210. For example, Figure 8 In the figure, the switch assembly 130 (conducting member 131 and circuit board 132) is embedded in the frame of the middle frame 121 as an example for explanation. The conducting member 131 of the switch assembly 130 is arranged facing the adapter 220 of the button 200, the adapter 220 passes through the first through hole 121c, and the end of the adapter 220 away from the pressing member 210 is connected to the conducting member 131. When the pressing member 210 is pressed, the pressing member 210 drives the adapter 220 to move toward the accommodating space 121a of the middle frame 121, and the adapter 220 can trigger the conducting member 131 to make the conducting member 131 contact and conduct with the circuit board 132.

[0082] Among them, the pressing piece 210 and the adapter 220 can be made of the same material. For example, the material of the pressing piece 210 and the material of the adapter 220 can both be plastic, metal or alloy. Of course, the pressing piece 210 and the adapter 220 can also be made of different materials. For example, the material of the pressing piece 210 can be a thermosetting polymer material. For example, the material of the pressing piece 210 can include polycarbonate (PC). For example, the material of the pressing piece 210 can include polycarbonate and glass fiber. For example, the material of the adapter 220 can be a thermoplastic polymer material. For example, the material of the adapter 220 can include thermoplastic polyurethane (TPU). Or, the material of the adapter 220 can include a thermoplastic polyester elastomer 140.

[0083] The pressing member 210 and the adapter 220 can be separately provided. For example, Fig. 9 As shown in , in some embodiments of the present application, a snap-in groove 211 can be provided on the inner side of the pressing member 210, and one end of the adapter 220 is snap-into the snap-in groove 211, thereby ensuring that the pressing member 210 and the adapter 220 do not undergo relative displacement, and preventing the two from colliding with each other and producing abnormal noise. The pressing member 210 and the adapter 220 can also be integrally formed. Exemplarily, the pressing member 210 and the adapter 220 can be manufactured by injection molding, so that the pressing member 210 and the adapter 220 are connected to each other.

[0084] Among them, the cross-section of the adapter 220 can be a regular shape such as a circle, a square, a trapezoid, etc., and of course it can also be an irregular shape. As long as the adapter 220 can trigger the conductive member 131 when it is subjected to the force transmitted by the pressing member 210, the embodiment of the present application does not limit the shape of the cross-section of the adapter 220.

[0085] In some embodiments of the present application, the elastic modulus of the pressing member 210 is set to be greater than the elastic modulus of the adapter 220. When the same force is applied to the pressing member 210 and the adapter 220, the deformation of the pressing member 210 is less than the deformation of the adapter 220, so as to enhance the user's pressing feel. Among them, the elastic modulus refers to the ability of an object to resist elastic deformation when subjected to force. The elastic modulus can be used as a dimension to measure the ease with which an object produces elastic deformation. The larger the elastic modulus, the greater the rigidity of the object, and the smaller the elastic deformation under a certain stress. The smaller the elastic modulus, the smaller the rigidity of the object, and the larger the elastic deformation under a certain stress.

[0086] In order to ensure the smoothness when pressing the button 200, it is inevitable to leave a gap between the button 200 and the middle frame 121, and these gaps will cause the button 200 to shake when it is not pressed, or even produce abnormal noise. For example, a gap needs to be left between the inner wall of the first through hole 121c and the outer wall of the adapter 220 to ensure that the adapter 220 does not get stuck when moving in the first through hole 121c, and these gaps will cause the button 200 to shake when it is not pressed. Alternatively, due to the manufacturing tolerance of the component size, a gap will also be generated, causing the button 200 to shake. Alternatively, during the long-term use of the conductive member 131, the elastic force is reduced, and the thickness of the conductive member 131 itself is reduced, so that the end of the adapter 220 away from the pressing member 210 cannot abut against the conductive member 131 when the button 200 is not pressed, causing the button 200 to shake along the extension direction of the adapter 220.

[0087] Fig.10 FIG. 2 is a schematic diagram of a key 200 of an electronic device 100 in a related art. Fig.10 As shown, in order to solve the above problem, in a related art, a foam 10 is disposed between the inner side of the pressing member 210 and the middle frame 121, and the foam 10 is interference fit with the inner side of the pressing key and the middle frame 121. However, in this way, the foam 10 can only reduce the shaking of the key 200 along the extending direction of the adapter 220 to a certain extent, and has little effect on the shaking of the key 200 perpendicular to the extending direction of the adapter 220.

[0088] In view of this, please continue to refer to Figure 8 and Fig. 9 Combined with Figure 5As shown, the button 200 provided in the embodiment of the present application further includes: a guide rod 230, one end of which is fixedly connected to the inner side of the pressing member 210. A groove 121d or a second through hole is provided on the middle frame 121 as an assembly position for accommodating the guide rod 230. Figure 5 In the example, the groove 121d is provided as the assembly position of the guide rod 230. In addition, elastic members 240 are provided at least on two opposite sides of the outer periphery of the guide rod 230. When the button 200 is assembled in the mounting groove 121b, the guide rod 230 is placed in the groove 121d or the second through hole, and the elastic members 240 on two opposite sides of the outer periphery of the guide rod 230 are interference-fitted with the middle frame 121.

[0089] Among them, the cross section of the guide rod 230 can be a regular shape such as a circle, a square, a trapezoid, etc., and of course it can also be an irregular shape. The embodiment of the present application does not limit the shape of the cross section of the guide rod 230. The material of the guide rod 230 can be the same as the material of the pressing member 210, or it can be different. Exemplarily, the material of the guide rod 230 can be a thermoplastic polymer material. For example, the material of the guide rod 230 can include TPU. Or, the material of the guide rod 230 can include a thermoplastic polyester elastomer 140. The embodiment of the present application does not limit the material of the guide rod 230. The guide rod 230 and the pressing member 210 can be set separately or integrally formed. Exemplarily, the pressing member 210 and the guide rod 230 can be manufactured by injection molding technology, so that the pressing member 210 and the guide rod 230 are connected to each other. It is only necessary to ensure that one end of the guide rod 230 is fixedly connected to the inner side of the pressing member 210. The embodiment of the present application does not limit the material of the elastic member 240. Exemplarily, the elastic member 240 can be a plastic member.

[0090] It is understandable that no matter what shape the cross section of the guide rod 230 is, it has two opposite sides. The two sides can be not only two faces, but also two points, and the two sides can also be two sides formed by multiple faces. Elastic members 240 are arranged on the opposite sides of the periphery of the guide rod 230, and the elastic members 240 can be arranged on the opposite sides of the periphery of the guide rod 230 by a series of existing connection methods such as bonding, welding, and clamping. Arranging the elastic members 240 on at least the opposite sides of the periphery of the guide rod 230 means that, under the premise that the elastic members 240 are arranged on the opposite sides of the periphery of the guide rod 230, the rest of the periphery of the guide rod 230 may be provided with the elastic members 240 or may not be provided with the elastic members 240.

[0091] The elastic members 240 on opposite sides of the outer periphery of the guide rod 230 are used for interference fit with the middle frame 121 of the electronic device 100. Figure 5As shown, the groove 121d serving as the assembly position of the guide rod 230 is a long strip-shaped groove along the length direction of the electronic device 100. Elastic members 240 can be provided on both sides of the outer periphery of the guide rod 230 along the thickness direction of the electronic device 100, and the elastic members 240 are interference-fitted with the structural boundary on the thickness of the middle frame 121. Of course, in other embodiments of the present application, elastic members 240 can also be provided on both sides of the outer periphery of the guide rod 230 along the length direction of the electronic device 100, and the elastic members 240 are interference-fitted with the structural boundary in the length direction of the middle frame 121. Elastic members 240 can also be provided on both sides of the outer periphery of the guide rod 230 along non-special directions of the electronic device 100.

[0092] Under this setting, the elastic parts 240 on both sides of the outer periphery of the guide rod 230 can fix the guide rod 230 together with the pressing part 210 and the adapter 220 on the middle frame 121 when the key 200 is in a static state, thereby alleviating or solving the problem of shaking and abnormal noise of the key 200.

[0093] The key 200 provided in the embodiment of the present application is provided with a guide rod 230, one end of which is fixedly connected to the inner side surface of the pressing member 210, and elastic members 240 are provided at least on two opposite sides of the outer periphery of the guide rod 230, and the elastic members 240 on the opposite sides of the outer periphery of the guide rod 230 are used to have an interference fit with the middle frame 121 of the electronic device 100, so that the key 200 can be fixed on the middle frame 121 in a static state, thereby alleviating or solving the problem of shaking and abnormal sound of the key 200. In addition, the key 200 provided in the embodiment of the present application has a simple structure and is easy to implement.

[0094] It is easy to understand that the key 200 solution provided in the embodiment of the present application is not only applicable to electronic devices 100, but also can be used in non-electronic devices 100, for example, the key 200 solution provided in the embodiment of the present application can be used in a keyboard.

[0095] Fig.11 This is a partial structural diagram of a key 200 of an electronic device 100 provided in an embodiment of the present application, with reference to Fig.11 As shown, the embodiment of the present application does not limit the number of guide rods 230. Fig.11 The number of the middle guide rod 230 is one.

[0096] Considering the appearance of the key 200 or the functionality of the key 200 (for example, the volume key needs to trigger two conductive members 131), the key 200 needs to have a certain length. When the pressing member is in the shape of a long strip (a state presented by a long object or a narrow object), the number of the guide rods 230 can be set to multiple, such as two, three or even more. For example, please continue to refer to Figure 8As shown, a plurality of guide rods 230 are arranged at intervals along the length direction of the pressing member 210. Figure 8 In the figure, two guide rods 230 are used for illustration. It is easy to understand that providing a plurality of guide rods 230 can further enhance the anti-shaking effect of the key 200 on the electronic device 100 .

[0097] Fig.12 This is a partial structural diagram of a key 200 of an electronic device 100 provided in an embodiment of the present application, with reference to Fig.12 As shown, as an alternative to the above-mentioned multiple guide rods 230, in some embodiments of the present application, the cross-section of the guide rod 230 can be set to an ellipse, and the major axis of the ellipse extends in a direction parallel to the length direction of the pressing member 210, so as to further enhance the anti-shaking effect of the key 200 on the electronic device 100. In some embodiments of the present application, the cross-section of the guide rod 230 can also be set to a rectangle, and the long side of the rectangle is parallel to the length direction of the pressing member 210, so as to further enhance the anti-shaking effect of the key 200 on the electronic device 100.

[0098] It is easy to understand that in a key 200 having a certain length, the cross section of the guide rod 230 is not limited to being set to a regular shape with a longer side such as an ellipse or a rectangle, but can also be an irregular shape with a longer side. The reason for setting the cross section of the guide rod 230 to an ellipse or a rectangle is that it is convenient to stamp the assembly position on the middle frame 121 to accommodate the guide rod 230.

[0099] Continue to refer Fig. 9 As shown, in some embodiments of the present application, elastic members 240 may be provided at least on opposite sides of the outer periphery of the adapter 220, and the elastic members 240 on opposite sides of the outer periphery of the adapter 220 are used for interference fit with the middle frame 121 of the electronic device 100. The anti-shaking principle is the same as the principle of providing the elastic member 240 on the guide rod 230, and will not be repeated here. It can be understood that the elastic member 240 provided on the adapter 220 cooperates with the elastic member 240 provided on the guide rod 230 to further enhance the anti-shaking effect of the key 200.

[0100] Continue to refer Fig. 9 As shown, in some embodiments of the present application, the elastic member 240 disposed on the periphery of the adapter 220 and / or the elastic member 240 disposed on the periphery of the guide rod 230 are annular. Wherein, "the elastic member 240 disposed on the periphery of the adapter 220 and / or the elastic member 240 disposed on the periphery of the guide rod 230" means that the elastic member 240 disposed on the periphery of the adapter 220 is annular or the elastic member 240 disposed on the periphery of the guide rod 230 is annular, or the elastic member 240 disposed on the periphery of the adapter 220 and the elastic member 240 disposed on the periphery of the guide rod 230 are both annular. Fig. 9In the description, an example is taken in which the elastic member 240 disposed on the periphery of the adapter 220 and the elastic member 240 disposed on the periphery of the guide rod 230 are both ring-shaped.

[0101] In this way, corresponding to the annular elastic member 240, an assembly position adapted or partially adapted to the adapter 220 or the guide rod 230 can be opened on the middle frame 121 of the electronic device 100, and the annular elastic member 240 can increase the interference fit area between the elastic member 240 and the middle frame 121, thereby further enhancing the anti-shake effect of the key 200 on the electronic device 100. In addition, the annular elastic member 240 can facilitate the assembly of the elastic member 240, for example, the annular elastic member 240 can be sleeved on the adapter 220 or the guide rod 230.

[0102] In some embodiments of the present application, the assembly position for accommodating the guide rod 230 provided on the middle frame 121 of the electronic device 100 can be set to be adapted to the guide rod 230. The assembly position for accommodating the guide rod 230 provided on the middle frame 121 is set to be adapted to the guide rod 230, which means that the assembly position for accommodating the guide rod 230 has the same shape as the guide rod 230, and the space of the assembly position only needs to be slightly larger than the volume of the guide rod 230, so that the guide rod 230 can move in the assembly position. At this time, the guide rod 230 can also serve as a guide member of the button 200 to guide the button 200. In addition, when the elastic member 240 sleeved on the outer periphery of the guide rod 230 is annular, the elastic member 240 can also have waterproof performance.

[0103] Fig.13 This is a schematic diagram of the exploded structure of the button 200 provided in an embodiment of the present application, refer to Fig.13 As mentioned, in some embodiments of the present application, an annular assembly groove 250 may be provided on the outer periphery of the adapter 220 and / or the outer periphery of the guide rod 230. For example, in FIG13, an annular assembly groove 250 is provided on the outer periphery of the adapter 220 and the outer periphery of the guide rod 230 as an example for explanation. The annular elastic member 240 is assembled in the annular assembly groove 250. The annular assembly groove 250 can fix the annular elastic member 240 to prevent the elastic member 240 from being separated from the adapter 220 or the guide rod 230 during the pressing process of the key 200. In addition, the annular assembly groove 250 can facilitate the assembly of the elastic member 240. The annular elastic member 240 only needs to be sleeved in the annular assembly groove 250, and the annular elastic member 240 is self-locked in the annular assembly groove 250 by its own elastic force.

[0104] Fig.14 This is a perspective view of a button 200 provided in an embodiment of the present application, see Fig.14 Combined with Figure 8 As shown, in some embodiments of the present application, the pressing member 210 has a first end and a second end (for example, Fig.14The inner side surface of the first end and the inner side surface of the second end are both provided with a buckle tongue 212. Fig.14 Combined with Figure 8 As shown, when the button 200 is in a non-pressed state in the electronic device 100 , the side of the buckle tongue 212 facing the pressing member 210 abuts against the middle frame 121 of the electronic device 100 to prevent the button 200 from being separated from the installation groove 121 b of the button 200 .

[0105] In some embodiments of the present application, the buckle tongue 212 (see Fig.14 The projection of the right buckle tongue 212 on the pressing member 210 is set to exceed the range of the pressing member 210, and the buckle tongue 212 on the second end (reference Fig.14 The orthographic projection of the left buckle tongue 212 on the pressing member 210 is set to not exceed the range of the pressing member 210. Figure 8 , a card slot 121e can be provided at one end of the installation slot 121b of the button 200 of the middle frame 121, and an elastic fastener 121f can be provided at the other end of the installation slot 121b of the button 200 of the middle frame 121. When installing the button 200, the buckle tongue 212 on the first end of the pressing member 210 can be first inserted into the card slot 121e, and then the buckle tongue 212 on the second end of the pressing member 210 can be pressed under the elastic fastener 121f to complete the assembly of the button 200. Alternatively, the elastic fastener 121f can be replaced by a rigid fastener. In this case, an insertion hole needs to be provided in the thickness direction of the middle frame 121. When the button 200 is placed in the installation slot 121b, the rigid fastener is placed in the installation slot 121b from the insertion hole and abuts against the buckle tongue 212 on the second end of the pressing member 210.

[0106] It is understandable that such a configuration can, on the one hand, facilitate the installation of the button 200. On the other hand, the opening area of ​​the installation slot 121b can be slightly larger than the area of ​​the pressing member 210, thereby preventing the installation slot 121b from being too large, improving the aesthetics, and reducing the possibility of the button 200 shaking in the installation slot 121b.

[0107] Fig.15 This is a schematic diagram of the structure of a key 200 provided in an embodiment of the present application, refer to Fig.15 As shown, in some embodiments of the present application, since the volume of the key 200 is too small, it is not suitable to set the guide rod 230. In this case, the adapter 220 is the guide rod 230. It can be understood that the adapter 220 has the function of pressing the conductive member 131 and also has the function of the guide rod 230 described above. For example, Fig.15In the embodiment, an annular elastic member 240 is sleeved on the adapter 220. The elastic member 240 and the middle frame 121 are interference-fitted to fix the key 200 on the middle frame 121 in a static state, thereby alleviating or solving the problem of the key 200 shaking and generating abnormal noise. When the first through hole 121c provided on the middle frame 121 to accommodate the adapter 220 is adapted to the adapter 220, the annular elastic member 240 can also play a waterproof role, preventing water stains from entering the interior of the electronic device 100 from the key 200.

[0108] Fig.16 This is a structural diagram of a key 200 of an electronic device 100 provided in an embodiment of the present application, refer to Fig.16 As shown, in some embodiments of the present application, the electronic device 100 may further include an elastomer 140, which is disposed between the inner side surface of the pressing member 210 and the middle frame 121. The elastomer 140 may reduce the possibility of the button 200 shaking in the extension direction of the adapter 220, thereby further enhancing the anti-shake effect of the button 200 on the electronic device 100.
