[0038] The key module 1 provided in this embodiment is applied to a housing 2 in an electronic device 4. The housing 2 is provided with a mounting groove 10 along its thickness direction. The outer peripheral side of the housing 2 is provided with a mounting hole 11 connected to the mounting groove 10. The mounting groove 10 includes an inner side wall 12 away from the mounting hole 11. The key module 1 includes a bracket 20, an elastic member 30, a pressure sensing member 40, and a button 50. The bracket 20 is arranged in the mounting groove 10 and abuts against the inner side wall 12. The bracket 20 includes a first fixing portion 21. The elastic member 30 is fixed to a side of the first fixing portion 21 away from the inner side wall 12, and opposite ends of the elastic member 30 protrude from opposite sides of the first fixing portion 21. The pressure sensing member 40 is fixed to the side of the elastic member 30 away from the first fixing portion 21, and the opposite ends of the pressure sensing member 40 protrude from the opposite sides of the first fixing portion 21. The bracket 20 cooperates with the inner side wall 12 to form a deformation space 41 surrounded by the inner side wall 12, the elastic member 30 and the pressure sensing member 40. The pressure sensing member 40 can be bent to the side of the first fixing portion 21 close to the inner side wall 12 and extend outside the mounting groove 10. A part of the button 50 is arranged in the mounting hole 11, and the other part extends into the mounting groove 10 and is connected to the opposite ends of the elastic member 30. When the button 50 is pressed, at least one end of the elastic member 30 can be elastically bent in the deformation space 41 relative to the first fixing portion 21, thereby driving the corresponding end of the pressure sensing member 40 to be elastically bent in the deformation space 41, thereby enabling the pressure sensing member 40 to sense the deformation of the elastic member 30.

[0039] The key module 1 can be applied to various electronic devices 4 such as mobile phones, computers, wearable devices, etc. The key module 1 can be pressed by the user, and when the user presses it, the corresponding function can be realized, such as volume control, taking pictures, locking the screen, screenshots, etc. In addition, the key module 1 is different from the existing key module 1. The key module 1 provided in this embodiment is a pressure-sensitive key module 1, which realizes the corresponding function by sensing the pressing force given by the user.

[0040] The key module 1 as a whole can be installed on the housing 2 in the electronic device 4. The housing 2 can also be called the middle frame and can play the role of a bearing component, so the housing 2 can also be called a bearing housing 2. Along the thickness direction of the housing 2, a mounting groove 10 can be opened on the upper end surface of the housing 2, that is, a side surface for installing the display module 3. The mounting groove 10 is used to install some components in the key module 1, and the subsequent display module 3 can cover the mounting groove 10 when it is installed in the housing 2, so as to cover and seal the mounting groove 10. At the same time, a mounting hole 11 connected to the mounting groove 10 is opened on the outer peripheral side of the housing 2. The mounting hole 11 can be used to install the button 50 in the key module 1, so that the user can press the button 50. And the mounting groove 10 includes two opposite side walls, wherein the mounting hole 11 will penetrate one side wall to connect to the mounting groove 10, so the side wall that penetrates and is close to the outside can be called the outer side wall 13, and the side wall opposite to the outer side wall 13 and arranged close to the inside is the inner side wall 12.

[0041] The key module 1 mainly includes a bracket 20, an elastic member 30, a pressure sensing member 40, and a key 50. The bracket 20 is mainly used to provide a mounting base, and other components in the key module 1 can be mounted on the bracket 20. The bracket 20 can be installed in the mounting groove 10 from the top of the housing 2 and abut against the inner wall 12. The bracket 20 includes a first fixing portion 21 for mounting other components. Optionally, the bracket 20 includes but is not limited to a waterproof bracket 20.

[0042] The elastic member 30 is an elastic member, such as an elastic steel sheet. The elastic member 30 can be fixed to the side of the first fixing portion 21 away from the inner wall 12, that is, the elastic member 30 is farther away from the inner wall 12 than the first fixing portion 21. The elastic member 30 can be fixed to the first fixing portion 21 by bonding, screw connection, clamping, hot melt connection, etc., and this embodiment is only schematically described by hot melt connection. For example, the elastic member 30 and the first fixing portion 21 can be bonded by hot melt columns.

[0043] In addition, the length of the elastic member 30 is greater than the length of the first fixed portion 21, and the middle portion of the elastic member 30 can be fixed on the first fixed portion 21, so that the opposite ends of the elastic member 30 can protrude from the opposite sides of the first fixed portion 21, which is convenient for the subsequent elastic bending of the opposite ends of the elastic member 30.

[0044] The pressure sensing component 40 is a component that can sense elastic deformation. Optionally, the pressure sensing component 40 includes but is not limited to a flexible printed circuit (FPC). The flexible printed circuit may be printed with pressure-sensitive ink. The pressure-sensitive ink can sense the micro-deformation of the elastic component 30, and then generate a corresponding electrical signal to realize the recognition and feedback of the user's press. The pressure sensing component 40 can be fixed on the elastic component 30 by bonding, screw connection, snap connection, hot melt connection, etc. This embodiment is only schematically illustrated by bonding. For example, the pressure sensing component 40 can be bonded to the elastic component 30 through the second adhesive layer 31. The second adhesive layer 31 includes but is not limited to hot pressing adhesive. The pressure sensing component 40 and the elastic component 30 can be regarded as a pressure sensing component, that is, the pressure sensing component 40 and the elastic component 30 are first installed together and then matched with other components. The pressure sensing component is a key component for realizing pressure sensing and reducing costs.

[0045] The pressure sensing element 40 can be fixed to the side of the elastic element 30 away from the first fixing portion 21, that is, the pressure sensing element 40 is farther away from the inner side wall 12 than the elastic element 30, so that the first fixing portion 21 can be used to form the deformation space 41. In addition, the length of the pressure sensing element 40 is also greater than the length of the first fixing portion 21. The middle part of the pressure sensing element 40 corresponds to the first fixing portion 21, so the opposite ends of the pressure sensing element 40 can protrude from the opposite sides of the first fixing portion 21. The pressure sensing element 40 on each side can cooperate with the elastic element 30 on the same side. When the elastic element 30 bends, the pressure sensing element 40 can sense the deformation of the elastic element 30.

[0046] Since the first fixing portion 21 is the component closest to the inner side wall 12, the first fixing portion 21 can abut against the inner side wall 12 to achieve the limit of the key module 1 and prevent the key module 1 from moving in the mounting groove 10 as a whole. In this embodiment, the first fixing portion 21 of the bracket 20 can also cooperate with the inner side wall 12 to form a deformation space 41 surrounded by the inner side wall 12, the elastic member 30 and the pressure sensing member 40. In other words, not all of the inner side wall 12 is in contact with the first fixing portion 21, but the middle part of the inner side wall 12 abuts against the first fixing portion 21, and since the first fixing portion 21 itself has a certain thickness, by arranging the elastic member 30 and the pressure sensing member 40 on the side of the first fixing portion 21 away from the inner side wall 12, the first fixing portion 21 itself can be used to better form the deformation space 41, that is, it is easier to form a gap between the inner side wall 12 and the elastic member 30 and the pressure sensing member 40, and a certain deformation space 41 is reserved, which is convenient for the subsequent elastic bending of the pressure sensing member 40 and the elastic member 30.

[0047] In addition, since the pressure sensing component 40 is arranged on the side of the first fixing portion 21 away from the inner wall 12, the present embodiment allows the pressure sensing component 40 to be first bent to the side of the first fixing portion 21 close to the inner wall 12, and then extend upward along the thickness direction of the shell 2 to the outside of the mounting groove 10, so as to facilitate the subsequent connection of the pressure sensing component 40 with other components.

[0048] The button 50 is a component pressed by the user, and is a key component for connecting the pressure sensing component with the user and transmitting the user's pressing force. The button 50 can be arranged in the mounting hole 11, so the user can press the button 50 from the side, a part of the button 50 is arranged in the mounting hole 11, and the other part can extend from the mounting hole 11 into the mounting groove 10 and be connected to the opposite ends of the elastic member 30. Optionally, the button 50 can be connected to the elastic member 30 by bonding, screw connection, clamping, hot melt connection, etc., and this embodiment is only schematically described by bonding. For example, the button 50 can be connected to the opposite ends of the elastic member 30 through the third bonding layer 51, and the third bonding layer 51 includes but is not limited to the back glue of the button 50. The two ends of the button 50 can be bonded to the two end surfaces of the elastic member 30 through the third bonding layer 51, which plays the role of bonding the button 50 and transmitting the pressing force of the button 50, and there is no need to add a C-shaped steel sheet to transmit the pressing force as in the related art.

[0049] It is worth noting that, in addition to the above two parts, the button 50 may also include other parts. For example, other parts of the button 50 protrude from the mounting hole 11 and thus protrude from the side of the housing 2, which further facilitates the user to press.

[0050] The key 50 is connected to the elastic member 30 instead of the pressure sensing member 40 to avoid the key 50 being directly connected to the pressure sensing member 40, thereby reducing the connection performance and even damaging the pressure sensing member 40. Therefore, in this embodiment, the key 50 is connected to the elastic member 30, and the pressure sensing member 40 is connected to the elastic member 30, so that the key 50 indirectly controls the elastic bending of the pressure sensing member 40 through the elastic member 30.

[0051] In addition, since the button 50 is connected to the elastic member 30 from the side of the first fixing portion 21 away from the inner wall 12, most of the button 50 is located on the side of the first fixing portion 21 away from the inner wall 12, and since the button 50 is long, if the pressure sensing member 40 is also disposed on the side of the first fixing portion 21 away from the inner wall 12, it will be inconvenient for the pressure sensing member 40 to extend upward to the outside of the installation slot 10 due to the existence of the button 50. Therefore, in this embodiment, the pressure sensing member 40 is first bent to the other side of the first fixing portion 21, so that it can be freed from the constraint of the button 50 and extend upward to the outside of the installation slot 10.

[0052] When the button 50 is pressed by the user, for example, when the user presses any one end or two opposite ends of the button 50, the button 50 will apply a certain pressure to the corresponding end of the elastic member 30. Since the middle of the elastic member 30 is fixed on the first fixing portion 21, the middle of the elastic member 30 will not be deformed, and only the pressed end will be deformed. At the same time, the first fixing portion 21 of the bracket 20 and the inner side wall 12 reserve a deformation space 41, so the end of the elastic member 30 can be elastically bent in the deformation space 41 toward the direction close to the inner side wall 12, and the bending will stop when the elastic member 30 abuts against the inner side wall 12. Similarly, since the pressure sensing member 40 is fixed on the elastic member 30, and the opposite ends of the pressure sensing member 40 also protrude from the first fixing portion 21, each end of the elastic member 30 is provided with a pressure sensing member 40. When at least one end of the elastic member 30 is elastically bent, the corresponding pressure sensing member 40 can be driven to be elastically bent in the deformation space 41 toward the direction close to the inner side wall 12. When the pressure sensing element 40 is elastically bent, the pressure sensing element 40 can sense the deformation of the elastic element 30, thereby generating a corresponding electrical signal and transmitting it to the processor. The processor can then obtain the pressure value of the user's pressing based on the electrical signal, and then trigger a corresponding action.

[0053] For example, when the user presses lightly, the volume can be increased, and when the user presses hard, the volume can be decreased. Alternatively, when the user presses only one end of the button 50, the volume can be controlled, when the user presses both ends of the button 50, the screen can be locked, or when the user presses from one end to the other, a screenshot can be taken.

[0054] In the related art, the button module 1 has many components, for example, it includes four steel sheets, and the steel sheets need to be welded together, the process flow is relatively complicated, and the material cost is high. The pressing module provided in this embodiment can achieve pressure-sensitive pressing only by cooperating with the bracket 20, the elastic member 30, the pressure sensing member 40, and the button 50. The button 50 transmits the user's pressing force to at least one end of the elastic member 30, thereby deforming the elastic member 30 and the pressure sensing member 40, and then generating an electrical signal. It replaces the solution of the C-shaped steel sheet and the steel sheet welding to transmit the pressing force in the related art, achieves the same effect, can save a C-shaped steel sheet and a welding process, and reduces the material cost and process cost. In summary, the button module 1 provided in this embodiment has a simple structure, low material and process cost, a reasonable solution, simple operation, and can save the material cost of 3 steel sheets and the corresponding welding cost.

[0055] Optionally, the length of the pressure sensing component 40 is smaller than the length of the elastic component 30. In other words, the opposite ends of the elastic component 30 protrude from the opposite ends of the pressure sensing component 40, so that the opposite ends of the button 50 are connected to the opposite ends of the elastic component 30, thereby deforming and bending the pressure sensing component 40 through the elastic component 30, thereby avoiding directly connecting the button 50 to the pressure sensing component 40 and damaging the pressure sensing component 40.

[0056] Please refer again Figure 3 and Figure 8 In this embodiment, the inner wall 12 includes a contact portion 121 and two spacer portions 122 arranged on opposite sides of the contact portion 121. The contact portion 121 is provided with a receiving groove 1210. A first positioning rib 24 is protruded from one side of the first fixing portion 21 close to the inner wall 12. The first positioning rib 24 is arranged in the receiving groove 1210 and contacts the bottom wall of the receiving groove 1210.

[0057] The inner side wall 12 includes a middle abutment portion 121 and two side spacing portions 122. The abutment portion 121 can also be referred to as the middle inner side wall 12 of the installation groove 10, the spacing portion 122 can also be referred to as the inner side walls 12 at both ends of the installation groove 10, and the outer side wall 13 can also be referred to as the outer side wall 13 of the installation groove 10. Since the deformation space 41 required by this embodiment does not need to be too large, and is limited by the size of the installation groove 10, the deformation space 41 will not be too large. Therefore, this embodiment can open a receiving groove 1210 in the abutment portion 121, and use the receiving groove 1210 to accommodate part of the first fixing portion 21. First, it can avoid the deformation space 41 being too large, and at the same time, it can also avoid the difficulty of preparing the bracket 20 due to reducing the thickness of the first fixing portion 21. For example, the bracket 20 is usually prepared by injection molding. If the thickness of the first fixing portion 21 is reduced too much, it will cause the thickness of the bracket 20 to be greatly different at various places, which increases the difficulty of injection molding.

[0058] In addition, a first positioning rib 24 is convexly provided on one side of the first fixing portion 21 close to the inner side wall 12. For example, two first positioning ribs 24 are provided at both ends of the first fixing portion 21 close to the inner side wall 12. The first positioning rib 24 is provided in the receiving groove 1210 and abuts against the bottom wall of the receiving groove 1210. Using the first positioning rib 24 to abut against the bottom wall of the receiving groove 1210 instead of using the first fixing portion 21 itself to abut against the bottom wall of the receiving groove 1210 can reduce the abutting area with the bottom wall of the receiving groove 1210, avoid the problem of poor abutting effect caused by the uneven bottom wall of the first fixing portion 21 and / or the receiving groove 1210, and the bracket 20 can also move relative to the mounting groove 10 after abutment. The abutting surface of the first positioning rib 24 is much smaller than the abutting surface of the first fixing portion 21, and can better abut against the bottom wall of the receiving groove 1210, thereby improving the stability of the abutment. In addition, since the pressure sensing component 40 will bend from the side of the first fixing portion 21 away from the inner wall 12 to the side of the first fixing portion 21 close to the inner wall 12, the accommodating groove 240 formed between the first positioning rib 24 and the first fixing portion 21 can be used to accommodate the pressure sensing component 40 bent to the side of the first fixing portion 21 close to the inner wall 12 to avoid interference between the pressure sensing component 40 and the inner wall 12.

[0059] Please refer to Figure 8 , Fig.10 - Fig.11 , Fig.10 It is a schematic diagram of the three-dimensional structure of the bracket in one embodiment of the present application. Fig.11 for Fig.10 A schematic diagram of the three-dimensional structure of the bracket from another perspective is shown. In this embodiment, the mounting groove 10 further includes an outer side wall 13 arranged opposite to the inner side wall 12, and a second positioning rib 261 is provided on the side of the first fixing portion 21 away from the inner side wall 12, and the second positioning rib 261 abuts against the outer side wall 13, so that the first positioning rib 24 abuts against the bottom wall of the accommodating groove 1210, and the first positioning rib 24 and the second positioning rib 261 are staggered along the extension direction of the first fixing portion 21.

[0060] A second positioning rib 261 may be provided on one side of the first fixing portion 21 close to the outer wall 13. For example, four second positioning ribs 261 may be provided in the middle area of ​​one side of the first fixing portion 21 close to the outer wall 13. When the bracket 20 is installed in the mounting groove 10, the second positioning rib 261 and the outer wall 13 collide with each other to generate an extrusion force to squeeze the first fixing portion 21, and the first fixing portion 21 then transmits the force to the first positioning rib 24, so that the first positioning rib 24 better abuts against the bottom wall of the accommodating groove 1210, and the stability of the key module 1 can also be improved. In other words, in the direction from the inner wall 12 to the outer wall 13, this embodiment can make the bracket 20 and the mounting groove 10 have an interference fit.

[0061] In addition, along the extension direction of the first fixing portion 21, that is, along the length direction of the first fixing portion 21, the first positioning rib 24 and the second positioning rib 261 are staggered. In other words, the orthographic projection of the first positioning rib 24 on the first fixing portion 21 and the orthographic projection of the second positioning rib 261 on the first fixing portion 21 do not overlap, and there is a certain distance. The first positioning rib 24 and the second positioning rib 261 are staggered by a reasonable distance (required for the bracket 20 to produce elastic deformation), so that the second positioning rib 261 can use its own deformation after being subjected to the resistance force to push the first positioning rib 24 to the bottom wall of the accommodating groove 1210, ensuring that there is a reasonable deformation space 41 between the elastic member 30 and the pressure sensing member 40 and the inner side wall 12. At the same time, it can be ensured that when the size of the bracket 20 and / or the mounting groove 10 fluctuates, the amount of extrusion between the positioning rib and the side wall of the mounting groove 10 will not make the bracket 20 unable to be assembled. In other words, when the size fluctuation occurs, the first fixing portion 21 between the first positioning rib 24 and the second positioning rib 261 can be bent and deformed to a certain extent, so that the bracket 20 can be installed in the installation groove 10 .

[0062] Please refer to Fig.11 - Fig.13 , Fig.12 It is a partial three-dimensional structural schematic diagram of a bracket, an elastic member, and a pressure sensing member in one embodiment of the present application. Fig.13 This is a schematic diagram of a bracket when it is not heated in one embodiment of the present application. In this embodiment, a positioning member 23 is provided on the side of the first fixing portion 21 away from the inner side wall 12, and the positioning member 23 includes a positioning portion 231 and a limiting portion 232 provided on the positioning portion 231 away from the first fixing portion 21, the periphery of the limiting portion 232 protrudes from the positioning portion 231, the positioning portion 231 penetrates the elastic member 30, and the limiting portion 232 abuts against the side of the elastic member 30 away from the first fixing portion 21.

[0063] The positioning member 23 is mainly used to limit and fix the elastic member 30 on the first fixing part 21. The positioning member 23 includes a positioning part 231 and a limiting part 232. The elastic member 30 is provided with a positioning hole, such as a U-shaped positioning hole. Specifically, the first fixing part 21 is provided with four positioning members 23, and correspondingly, the elastic member 30 is provided with four U-shaped positioning holes. The position of the elastic member 30 can be limited by making the positioning part 231 pass through the positioning hole, thereby improving the accuracy of the position of the elastic member 30 during installation. The limiting part 232 is arranged above the positioning part 231 and the periphery of the limiting part 232 protrudes from the positioning part 231. Therefore, after the positioning part 231 passes through the elastic member 30, the limiting part 232 can be used to abut against the side of the elastic member 30 away from the first fixing part 21, thereby fixing the elastic member 30 to the first fixing part 21, preventing the elastic member 30 from detaching, and also fixing the non-deformed area in the middle of the elastic member 30.

[0064] Optionally, the positioning member 23 includes but is not limited to a hot melt column. When the hot melt column is not hot-melted, it only includes a positioning portion 231 without a limiting portion 232. At this time, the hot melt column can penetrate the positioning hole of the elastic member 30 to limit the elastic member 30. The positioning portion 231 protrudes from the elastic member 30, and then the portion of the positioning portion 231 protruding from the elastic member 30 can be heated to soften it and gradually become the limiting portion 232. The periphery of the limiting portion 232 gradually protrudes from the positioning portion 231 and abuts against the side of the elastic member 30 away from the first fixing portion 21. Therefore, the hot melt heat fixes the elastic member 30 through the hot melt column positioning + hot melt column fixing, so that the middle area of ​​the elastic member 30 is tightly combined with the bracket 20. The above content can also be understood as the elastic member 30 is first assembled to the bracket 20 through hot melt column positioning, and then the hot melt column is hot-melted to fix the middle non-deformed area of ​​the elastic member 30.

[0065] It is worth noting that the elastic member 30 is first fixed to the pressure sensing member 40 , and then the elastic member 30 is fixed to the bracket 20 through a hot melt column, and then they are assembled together into the mounting groove 10 of the housing 2 .

[0066] It is worth noting that by using the positioning member 23 to fix the elastic member 30 on the side of the first fixing portion 21 away from the inner wall 12, it is possible to avoid the positioning member 23 being disposed on the side of the first fixing portion 21 close to the inner wall 12, which affects the first fixing portion 21 from abutting against the inner wall 12. For example, if the positioning member 23 is disposed on the side of the first fixing portion 21 close to the inner wall 12, the positioning member 23 can also limit and fix the elastic member 30. However, in this case, the first fixing portion 21 or the first positioning rib 24 cannot be used to abut against the inner wall 12, but the positioning member 23 abuts against the inner wall 12, which not only has low stability, but also the size of the deformation space 41 cannot be effectively notified by the hot melt method, and the error between different components is large.

[0067] Optionally, an avoidance space 41 a is provided on the pressure sensing component 40 to avoid the hot melt column, so as to prevent the hot melt column from limiting and fixing the pressure sensing component 40 .

[0068] Please refer again Fig.11 In this embodiment, the bracket 20 also includes a bracket body 25 connected to the first fixing portion 21, and two second fixing portions 26 connected to the opposite ends of the bracket body 25, and the two second fixing portions 26 are arranged on opposite sides of the first fixing portion 21, and the two second fixing portions 26 are fixed to the bottom wall of the mounting groove 10.

[0069] In addition to the first fixing portion 21, the bracket 20 may also include a bracket body 25 and two second positioning portions 231. The length direction of the bracket body 25 is consistent with the length direction of the mounting groove 10. The first fixing portion 21 and the two second fixing portions 26 are connected to the same side of the bracket body 25, and the two second fixing portions 26 are arranged on opposite sides of the first fixing portion 21. The two second fixing portions 26 can be fixed to the bottom wall of the mounting groove 10 to improve the stability of the bracket 20 in the height direction. Optionally, the second fixing portion 26 can be fixed to the bottom wall of the mounting groove 10 by bonding, screw connection, clamping, hot melt connection, etc. This embodiment is only schematically described by bonding. For example, the second fixing portion 26 and the bottom wall of the mounting groove 10 can be fixedly connected by a fourth adhesive layer 27. The fourth adhesive layer 27 includes but is not limited to the adhesive backing for fixing the bracket 20.

[0070] Please refer to Figure 1 , Fig.11 ,as well as Fig.14 , Fig.14 for Figure 7 The illustrated schematic partial cross-sectional view of the key module when it is mounted on the housing in another direction. In this embodiment, two buckle positions 250 are provided on opposite sides of the bracket body 25, and buckle grooves 14 are provided on the other two side walls of the mounting groove 10 in a direction perpendicular to the inner side wall 12 and the outer side wall 13. When the bracket 20 is mounted in the mounting groove 10, the buckle positions 250 can be set in the buckle grooves 14, and a reasonable buckling amount is set to prevent the second fixing portion 26 from loosening or falling off after the fixed connection with the mounting groove 10 fails, resulting in poor waterproofing.

[0071] Please refer again Fig. 9 In this embodiment, the bottom wall of the installation groove 10 is further provided with a positioning groove 15. When the bracket 20 is installed in the installation groove 10, the first fixing portion 21 can be arranged in the positioning groove 15, thereby realizing the positioning installation of the bracket 20 and improving the position accuracy of the bracket 20 during installation. At the same time, since the pressure sensing component 40 will go around from the side of the first fixing portion 21 away from the inner wall 12 through the side of the first fixing portion 21 away from the bracket body 25 to the side of the first fixing portion 21 close to the inner wall 12, the bent and wound part of the pressure sensing component 40 can also be arranged in the positioning groove 15. At this time, the positioning groove 15 can also be called a pressure sensing component bending avoidance groove.

[0072] Please refer to Fig.10 - Fig.11 ,as well as Fig.15 , Fig.15 for Figure 8The illustrated partial enlarged view of the key module when it is installed on the housing. In this embodiment, the installation slot 10 also includes an outer side wall 13 arranged opposite to the inner side wall 12, and the second fixing portion 26 is provided with a third positioning rib 262 and a fourth positioning rib 263 on opposite sides thereof, the third positioning rib 262 abuts against the outer side wall 13, and the fourth positioning rib 263 abuts against the inner side wall 12, and along the arrangement direction of the two second fixing portions 26, the third positioning rib 262 and the fourth positioning rib 263 are staggered.

[0073] On the basis that the bracket 20 includes the second fixing portion 26, a third positioning rib 262 and a fourth positioning rib 263 may be provided on opposite sides of the second fixing portion 26, that is, the third positioning rib 262 is provided on the side of the second fixing portion 26 close to the outer wall 13, for example, each second fixing portion 26 is provided with a third positioning rib 262, and the third positioning rib 262 is provided at one end of the second fixing portion 26 close to the first fixing portion 21. A fourth positioning rib 263 is provided on the side of the second fixing portion 26 close to the inner wall 12, for example, each second fixing portion 26 is provided with a fourth positioning rib 263, and the fourth positioning rib 263 is provided at one end of the second fixing portion 26 away from the first fixing portion 21. When the bracket 20 is installed in the installation groove 10, the third positioning rib 262 can abut against the outer wall 13, and the fourth positioning rib 263 can abut against the inner wall 12. The third positioning rib 262 and the fourth positioning rib 263 are respectively provided with a reasonable gap to further position the bracket 20 in the direction from the inner wall 12 to the outer wall 13, thereby improving the stability of the bracket 20. In other words, the arrangement of the third positioning rib 262 and the fourth positioning rib 263 can enable the bracket 20 to be interference-fitted with the mounting slot 10 .

[0074] In addition, along the arrangement direction of the two second fixing portions 26, the third positioning rib 262 and the fourth positioning rib 263 are staggered. For example, the third positioning rib 262 mentioned above is arranged at one end of the second fixing portion 26 close to the first fixing portion 21, and the fourth positioning rib 263 is arranged at one end of the second fixing portion 26 away from the first fixing portion 21. It can also be understood that the orthographic projection of the third positioning rib 262 on the second fixing portion 26 and the orthographic projection of the fourth positioning rib 263 on the second fixing portion 26 do not overlap and have a gap. By staggering the third positioning rib 262 and the fourth positioning rib 263, it can be ensured that when the size of the bracket 20 and / or the installation groove 10 fluctuates, the amount of extrusion between the positioning rib and the side wall of the installation groove 10 will not make the bracket 20 unable to be assembled. In other words, when the size fluctuates, the second fixing portion 26 between the third positioning rib 262 and the fourth positioning rib 263 can be bent and deformed to a certain extent, so that the bracket 20 can be installed in the installation groove 10.

[0075] Please refer again Fig. 9 and Fig.11In this embodiment, the bracket 20 also includes a bracket body 25 connected to the first fixing portion 21, and the bracket body 25 includes a first part 251 and a second part 252. The first part 251 is connected to the first fixing portion 21, and the second part 252 is connected to the side of the first part 251 away from the first fixing portion 21. The periphery of the second part 252 is protruded with a first sealing rib 253, and the first sealing rib 253 abuts against the side wall of the mounting groove 10.

[0076] The bracket body 25 may include a first part 251 and a second part 252. The first part 251 is mainly provided with a first fixing part 21 and two second fixing parts 26, and the second part 252 is connected to the top of the first part 251. Optionally, the first part 251, the first fixing part 21 and the two second fixing parts 26 are an integrated structure, for example, made of hard rubber. On this basis, a second part 252 with a reasonable thickness can be formed on the top of the first part 251 by a two-color injection molding process. The second part 252 is made of silicone. The hardness of the first part 251 is relatively large, which can improve the overall strength of the bracket 20. The second part 252 is relatively soft. Therefore, in this embodiment, a first sealing rib 253 can be convexly provided on the periphery of the second part 252. The first sealing rib 253 is interference-fitted with the mounting groove 10, so that the first sealing rib 253 abuts against the side wall of the mounting groove 10, which can not only further improve the connection stability between the bracket 20 and the mounting groove 10, but also improve the sealing performance between the bracket 20 and the mounting groove 10, thereby improving the waterproof performance. Furthermore, since the second portion 252 and the first sealing rib 253 are relatively soft, they can form a larger deformation with the side wall of the mounting groove 10, which can further improve the sealing performance.

[0077] In summary, the button module 1 provided in this embodiment can achieve IPX8 waterproof performance and is a key structural component for assembling and fixing the pressure sensing component, wherein IPX8 is the highest level of waterproof rating, indicating that the electronic device 4 can be immersed in water for 30 minutes at a depth of 1.5-30 meters below the surface without being affected by water and without leaking.

[0078] Please refer again Figure 1 , Figure 3 ,as well as Fig. 9 - Fig.10In this embodiment, the inner wall 12 is provided with a glue overflow groove 123 at the opening of the mounting groove 10, and the pressure sensing member 40 includes a pressure sensing portion 43 fixed to the elastic member 30 away from the first fixing portion 21, a bending portion 43a connected to the pressure sensing portion 43 and bent to the first fixing portion 21 near the inner wall 12, and a first extension portion 44 connected to the bending portion 43a and extending along the thickness direction of the shell 2, the first extension portion 44 extends to the outside of the mounting groove 10, and the first extension portion 44 corresponds to the glue overflow groove 123. The key module 1 also includes a first sealing member 60, a part of the first sealing member 60 is provided on the side of the second portion 252 away from the first portion 251 to seal the gap between the first sealing rib 253 and the side wall of the mounting groove 10, and another part of the first sealing member 60 is provided in the glue overflow groove 123 to fix the first extension portion 44.

[0079] An overflowing glue groove 123 may be provided at the top of the inner wall 12, i.e., at the opening of the inner wall 12 close to the mounting groove 10. The pressure sensing component 40 includes a pressure sensing portion 43, a bending portion 43a, and a first extension portion 44. The pressure sensing portion 43 is the portion fixed to the elastic component 30 mentioned above. The bending portion 43a is connected to the pressure sensing portion 43, and is bent from the side of the first fixing portion 21 away from the inner wall 12 through the bottom of the first fixing portion 21 to the side of the first fixing portion 21 close to the inner wall 12. The first extension portion 44 is connected to the bending portion 43a and the first extension portion 44 may extend vertically upward along the thickness direction of the housing 2 to the outside of the mounting groove 10. In this embodiment, the first extension portion 44 may be provided corresponding to the overflowing glue groove 123. For example, the pressure sensing component 40 includes one first extension portion 44, and two overflowing glue grooves 123 are also provided, and one first extension portion 44 corresponds to one overflowing glue groove 123.

[0080] Optionally, the surface of the first fixing portion 21 close to the inner wall 12 is a fitting surface 210, and the bent portion 43a can be fixed to the first fixing portion 21 by bonding, screw connection, clamping, hot melt connection, etc., and this embodiment is only schematically described by bonding. For example, the bent portion 43a is bonded to the first fixing portion 21 through the first adhesive layer 22, and the first adhesive layer 22 includes but is not limited to a pressure-sensitive adhesive.

[0081] In addition, the key module 1 further includes a first sealant 60, which mainly plays a role of sealing. The first sealant 60 includes but is not limited to glue, that is, the first sealant 60 is initially in liquid or colloidal state, and can form a solid first sealant 60 after solidification. A part of the first sealant 60 is arranged on the side of the second part 252 away from the first part 251, and can be mainly arranged between the first sealing rib 253 of the second part 252 and the side wall of the installation groove 10. Due to the arrangement of the first sealing rib 253, the first sealant 60 can be prevented from flowing into the bottom of the installation groove 10 to affect the normal operation of the key module 1, so as to seal the gap between the first sealing rib 253 and the side wall of the installation groove 10, thereby further improving the waterproof performance of the key module 1 and the housing 2.

[0082] Since the first sealing member 60 has fluidity at the beginning, the first sealing member 60 can also flow into the overflowing glue groove 123, and the overflowing glue groove 123 can accommodate excess first sealing member 60. After solidification, the first sealing member 60 is disposed in the overflowing glue groove 123 and surrounds the first extension portion 44, so that the first extension portion 44 can be fixed to the side wall of the mounting groove 10, with a good fixing effect.

[0083] In summary, in this embodiment, glue is dispensed around the second portion 252, and the glue can fill the space between the bracket 20 and the side wall of the mounting groove 10 and the space around the first extension portion 44 due to its own fluidity to further achieve the IPX8 waterproof requirement. The setting of the overflow groove 123 facilitates the excess glue to flow to the periphery of the first extension portion 44, thereby further ensuring the IPX8 waterproof requirement.

[0084] Optionally, the second part 252, or the second part 252 and the first part 251 include a middle part 254 and a surrounding part 255 arranged on the middle part 254, and the middle part 254 protrudes from the surrounding part 255, so that the middle part 254 is higher, so that when dispensing glue, the glue can flow toward the surrounding part 255 along the slope of the middle part 254 and the surrounding part 255, thereby sealing the second part 252 and the side wall of the installation groove 10.

[0085] Optionally, the second portion 252 is provided with an anti-fool structure 256, which may be a notch. The anti-fool structure 256 may be used to prevent the bracket 20 from being installed upside down.

[0086] Please refer to Figure 1 - Figure 3 ,as well as Fig.16 , Fig.16 for Figure 7The schematic diagram of a partial cross section of the key module when it is installed in the housing along another direction. In this embodiment, the pressure sensing component 40 includes a second extension portion 45 and a through portion 46 in addition to the pressure sensing portion 43 and the first extension portion 44. The second extension portion 45 extends on the surface of the housing 2 where the mounting groove 10 is opened. Then, a through hole 16 can be opened at a certain point of the housing 2. The through portion 46 can penetrate the through hole so that the pressure sensing component 40 is arranged in the housing 2. The end of the through portion 46 away from the second extension portion 45 is provided with a buckle portion 47, such as a BTB connector. The buckle portion 47 can be used to buckle the pressure sensing component 40 to the small board to achieve electrical performance connection.

[0087] Please refer to Figure 1 - Figure 3 ,as well as Fig.16 - Fig. 20 , Fig.17 for Figure 7 The key module shown is a partial cross-sectional schematic diagram along another direction when it is mounted on the housing. Fig.18 Schematic diagram of a via bracket in one embodiment of the present application. Fig.19 for Figure 1 A schematic diagram of the partial three-dimensional structure of the shell from another perspective is shown. Fig. 20 for Figure 7 The key module shown is a schematic diagram of a partial three-dimensional structure when the third seal is removed from another perspective when the key module is installed in the shell. In this embodiment, a step 17 is provided on the hole wall of the through hole 16, and the key module 1 also includes a through hole bracket 70, which is a key structural component for achieving IPX8 waterproof at the position of the through hole 16. Bracket buckles 71 are provided on opposite sides of the through hole 16, and the bracket buckles 71 overlap the steps 17 to prevent the through hole bracket 70 from falling. The through hole bracket 70 also includes a hanging foot structure 72, which can be snapped to the other side of the shell 2, thereby further improving the stability of the through hole bracket 70. Therefore, the through hole bracket 70 can be snapped to the opposite sides of the shell 2 through the bracket buckle 71 and the hanging foot structure 72 to prevent the bracket 20 from falling.

[0088] Optionally, after the via bracket 70 is installed on the housing 2 , an avoidance groove 18 may be formed around the via bracket 70 , and the avoidance groove 18 may accommodate the through portion 46 , thereby avoiding interference between the via bracket 70 and the through portion 46 .

In addition, the key module 1 further includes a third sealant 80, which includes but is not limited to glue dispenser, and the glue dispenser can be filled into the groove 19. The glue can fill the space between the via bracket 70 and the housing 2 and the space around the through-hole portion 46 under the action of its own fluidity, thereby sealing the via bracket 70 and the housing 2, further improving the waterproof performance to achieve the IPX8 waterproof requirement.

[0090] Please refer to Fig. 9 and Fig.21 , Fig.21 Schematic diagram of the three-dimensional structure of a key in an embodiment of the present application. In this embodiment, the key 50 includes a key body 52 and a second sealing member 53, the key body 52 is disposed in the mounting hole 11 and connected to opposite ends of the elastic member 30, a receiving groove 520 is disposed on the outer peripheral side of the key body 52, the second sealing member 53 is disposed in the receiving groove 520, a second sealing rib 531 is convexly disposed on the periphery of the second sealing member 53, the second sealing rib 531 abuts against the side wall of the mounting hole 11, and the second sealing member 53 and the key body 52 are surrounded to form an ash storage groove 530, the opening direction of the ash storage groove 530 faces the opening direction of the mounting hole 11.

[0091] The key 50 includes a key body 52 and a second sealing member 53. The key body 52 is the above-mentioned part disposed in the mounting hole 11 and connected to the opposite ends of the elastic member 30, and is mainly used to be pressed by the user and transmit the pressing force of the user. A receiving groove 520 is provided on the outer peripheral side of the key body 52. ​​The second sealing member 53 is put on the key body 52 by machine or manually, and the second sealing member 53 is disposed in the receiving groove 520. At the same time, the second sealing member 53 is located in the mounting hole 11. A second sealing rib 531 is convexly provided on the periphery of the second sealing member 53. By making the second sealing member 53 and the mounting hole 11 have an interference fit, the second sealing rib 531 abuts against the side wall of the mounting hole 11, thereby improving the sealing performance between the key 50 and the mounting hole 11, so as to prevent dust or foreign matter from entering the mounting groove 10 and affecting the deformation and function of the module.

[0092] In addition, the second sealing rib 531 is arranged at one end of the second sealing member 53 close to the bracket 20, so that the second sealing member 53 can be surrounded by the button body 52 to form an ash storage groove 530, and the opening direction of the ash storage groove 530 is oriented towards the opening direction of the mounting hole 11, that is, the opening direction of the ash storage groove 530 is outward, which can be used to accommodate foreign matter from the outside that enters the gap between the button 50 and the mounting hole 11 in the shell 2, thereby preventing foreign matter from entering the mounting groove 10.

[0093] Please refer to Fig. 22 , Fig. 22This is an exploded view of an electronic device in an embodiment of the present application. This embodiment provides an electronic device 4, which includes a display module 3, a housing 2, and a key module 1 as provided in the above embodiment of the present application, wherein the housing 2 is provided with a mounting groove 10 along its thickness direction, and a mounting hole 11 is provided on the outer peripheral side of the housing 2 to communicate with the mounting groove 10, the key module 1 is installed in the mounting groove 10 and the mounting hole 11, and a portion of the pressure sensing component 40 in the key module 1 extends outside the mounting groove 10, and the display module 3 is provided in the housing 2 and covers the mounting groove 10.

[0094] The electronic device 4 provided in this embodiment includes but is not limited to mobile terminals such as mobile phones, tablet computers, laptop computers, PDAs, personal computers (PCs), personal digital assistants (PDAs), portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, etc. This embodiment does not limit the types of electronic devices 4, and only uses mobile phones for schematic illustration.

[0095] The relationship between the housing 2 and the key module 1 has been described in detail above in this application, and will not be repeated in this embodiment. The display module 3 has a display function and can be arranged on the side of the housing 2 where the mounting groove 10 is opened, thereby covering the mounting groove 10 so that the user cannot see the mounting groove 10 from the appearance, thereby effectively protecting the key module 1.

[0096] When assembling the electronic device 4, the elastic member 30 can be first fixed on the pressure sensing member 40, and then the elastic member 30 can be fixed on the first fixing portion 21 of the bracket 20 through the hot melt column, and then the above components can be installed in the installation groove 10. At this time, the bracket 20 can be stably set in the installation groove 10 and the first fixing portion 21 abuts against the inner wall 12. The pressure sensing member 40 is wound around the side of the first fixing portion 21 close to the inner wall 12 and then extends out of the installation groove 10. Then, the button 50 is installed from the installation hole 11 so that the button 50 connects the opposite ends of the elastic member 30, and then the first sealing member 60 is used to seal the installation groove 10.

[0097] Then the pressure sensing element 40 is passed through the via hole 16 of the housing 2 and connected to the small board to achieve electrical connection. Then the via hole bracket 70 is installed at the via hole 16 of the housing 2, and finally the via hole bracket 70 is sealed with the third sealing member 80.

[0098] In the related art, the key module 1 has many components, for example, including four steel sheets, and the steel sheets need to be welded together, the process flow is relatively complicated, and the material cost is high. The electronic device 4 provided in this embodiment can achieve pressure-sensitive pressing only by cooperating with the bracket 20, the elastic member 30, the pressure sensing member 40, and the button 50. The button 50 transmits the user's pressing force to at least one end of the elastic member 30, thereby deforming the elastic member 30 and the pressure sensing member 40, and then generating an electrical signal. It replaces the scheme of welding the pressing force of the C-shaped steel sheet and the steel sheet in the related art, achieves the same effect, saves a C-shaped steel sheet and a welding process, and reduces the material cost and process cost.
