[0038] The key module 1 provided in this embodiment is applied to a housing 2 in an electronic device 4, wherein the housing 2 is provided with a mounting groove 10 along its thickness direction, and a mounting hole 11 connected to the mounting groove 10 is provided on the outer peripheral side of the housing 2, and the mounting groove 10 includes an inner side wall 12 away from the mounting hole 11, and the key module 1 includes a bracket 20, an elastic member 30, a pressure sensing member 40, and a key 50. The bracket 20 is arranged in the mounting groove 10, and the bracket 20 includes a first fixing portion 21, and the elastic member 30 is fixed to a side of the first fixing portion 21 close to 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 abuts against the inner side wall 12. The opposite ends of the pressure sensing member 40 protrude from the opposite sides of the first fixing portion 21. The pressure sensing member 40 cooperates with the inner side wall 12 to form a deformation space 41 surrounded by the inner side wall 12, and the pressure sensing member 40 can extend from the side of the first fixing portion 21 close to the inner side wall 12 to the outside of 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. 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 component, such as an elastic steel sheet. The elastic member 30 can be fixed to the side of the first fixing part 21 close to the inner wall 12, that is, the elastic member 30 is closer to the inner wall 12 than the first fixing part 21. And the elastic member 30 and the first fixing part 21 can be fixed thereon by bonding, screw connection, clamping, hot melt connection, etc., and this embodiment is only schematically illustrated by bonding. For example, the elastic member 30 and the first fixing part 21 can be bonded by the first adhesive layer 22, and the first adhesive layer 22 includes but is not limited to adhesive. In addition, the length of the elastic member 30 is greater than the length of the first fixing part 21, and the middle part of the elastic member 30 can be fixed on the first fixing part 21, so that the opposite ends of the elastic member 30 can protrude from the opposite sides of the first fixing part 21, so that the opposite ends of the elastic member 30 can be elastically bent later.

[0043] 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.

[0044] The pressure sensing component 40 can be fixed on the side of the elastic component 30 away from the first fixed portion 21, that is, the pressure sensing component 40 is closer to the inner wall 12 than the elastic component 30. This makes it easier for the pressure sensing component 40 to extend upward to the outside of the mounting groove 10 on the side close to the inner wall 12 to avoid subsequent interference with the button 50, so that the pressure sensing component 40 can subsequently extend to other positions of the shell 2 to connect to the circuit board.

[0045] In addition, the length of the pressure sensing component 40 is also greater than the length of the first fixed portion 21. The middle portion of the pressure sensing component 40 corresponds to the first fixed portion 21. Therefore, the opposite ends of the pressure sensing component 40 can protrude from the opposite sides of the first fixed portion 21. The pressure sensing component 40 on each side can cooperate with the elastic component 30 on the same side. When the elastic component 30 bends, the pressure sensing component 40 can sense the deformation of the elastic component 30.

[0046] Since the pressure sensing component 40 is the component closest to the inner side wall 12, the pressure sensing component 40 can abut against the inner side wall 12 to limit the key module 1 and prevent the key module 1 from moving as a whole in the installation groove 10. In addition, the present embodiment can also make the pressure sensing component 40 cooperate with the inner side wall 12 so that the inner side wall 12, the elastic component 30 and the pressure sensing component 40 can be surrounded to form a deformation space 41. In other words, not all inner side walls 12 are in contact with the pressure sensing component 40, but the middle part of the pressure sensing component 40 corresponding to the first fixing part 21 abuts against the inner side wall 12, and the two ends of the pressure sensing component 40 have a spacing with the remaining inner side walls 12. In this way, a certain deformation space 41 can be reserved between the remaining inner side walls 12 and the pressure sensing component 40 and the elastic component 30, so as to facilitate the subsequent elastic bending of the pressure sensing component 40 and the elastic component 30.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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. Since the button 50 is relatively long, if the pressure sensing member 40 is also arranged on the side of the first fixing portion 21 away from the inner wall 12, the presence of the button 50 will make it inconvenient for the pressure sensing member 40 to extend upward to the outside of the mounting groove 10.

[0051] 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, a deformation space 41 is reserved by the cooperation between the pressure sensing member 40 and the inner side wall 12, 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, a pressure sensing member 40 is provided on each end of the elastic member 30. 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.

[0052] 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.

[0053] 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 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 related art of C-shaped steel sheet and steel sheet welding to transmit pressing force, achieves the same effect, saves a C-shaped steel sheet and a welding process, and reduces material and process costs. In summary, the button module 1 provided in this embodiment has a simple structure and low material and process costs.

[0054] Optionally, the length of the pressure sensing member 40 is shorter than that of the elastic member 30. In other words, the opposite ends of the elastic member 30 protrude from the opposite ends of the pressure sensing member 40, so that the opposite ends of the key 50 are connected to the opposite ends of the elastic member 30, thereby deforming and bending the pressure sensing member 40 through the elastic member 30. This can avoid directly connecting the key 50 to the pressure sensing member 40, thereby damaging the pressure sensing member 40.

[0055] Please refer to Figure 1 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 protrudes from the two spacer portions 122, the pressure sensing component 40 contacts the contact portion 121, and the opposite ends of the pressure sensing component 40 are spaced apart from the two spacer portions 122.

[0056] The inner side wall 12 includes a middle abutting portion 121 and two side spacing portions 122. The abutting portion 121 can also be referred to as the middle inner side wall 12 of the mounting groove 10, the spacing portions 122 can also be referred to as the inner side walls 12 at both ends of the mounting groove 10, and the outer side wall 13 can also be referred to as the outer side wall 13 of the mounting groove 10. In this embodiment, the abutting portion 121 can protrude from the spacing portion 122, so that a reasonable drop is set between the abutting portion 121 and the two end spacing portions 122. When the pressure sensing component 40 abuts against the abutting portion 121, the opposite ends of the pressure sensing component 40 are spaced from the two spacing portions 122, thereby providing a reasonable deformation space 41 for the elastic component 30 and the pressure sensing component 40.

[0057] Please refer to Fig.10 , Fig.10 The following is a schematic diagram of the bracket, the elastic member, and the pressure sensing member in an embodiment of the present application. In this embodiment, the first fixing portion 21 is provided with a first positioning portion 23, and the elastic member 30 is provided with a second positioning portion 32. The first positioning portion 23 and the second positioning portion 32 cooperate with each other to limit the elastic member 30 to the first fixing portion 21.

[0058] The first positioning portion 23 is one of the positioning column and the positioning hole, and the second positioning portion 32 is the other of the positioning column and the positioning hole. When the first positioning portion 23 is the positioning column, the second positioning portion 32 is the positioning hole. When the first positioning portion 23 is the positioning hole, the second positioning portion 32 is the positioning column. This embodiment is only schematically described with the first positioning portion 23 being the positioning column and the second positioning portion 32 being the positioning hole. For example, the first fixing portion 21 is provided with two positioning columns, and the elastic member 30 is provided with two positioning holes. The positioning columns can penetrate the positioning holes to limit the elastic member 30, thereby improving the accuracy of the position of the elastic member 30 when it is installed.

[0059] Optionally, a receiving hole 42 corresponding to the positioning hole is provided on the pressure sensing member 40, and the receiving hole 42 is used to accommodate an extra positioning column. When the positioning column is too high and protrudes out of the elastic member 30, an receiving hole 42 can be provided on the pressure sensing member 40 to accommodate the extra positioning column to avoid interference between the positioning column and the pressure sensing member 40.

[0060] Please refer to Figure 3 , Fig. 9 ,as well as Fig.11 , Fig.11 Schematic diagram of the three-dimensional structure of the bracket in one embodiment of the present application. In this embodiment, the mounting groove 10 also includes an outer wall 13 arranged opposite to the inner wall 12, and a first positioning rib 24 is provided on the side of the first fixing portion 21 away from the elastic member 30, and the first positioning rib 24 abuts against the outer wall 13, so that the pressure sensing member 40 abuts against the inner wall 12.

[0061] A first positioning rib 24 may be provided on one side of the first fixing portion 21 close to the outer wall 13. For example, two first positioning ribs 24 may be provided on opposite ends 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 first positioning rib 24 and the outer wall 13 contact each other to generate an extrusion force to squeeze the pressure sensing component 40. For example, the adhesive backing of the first adhesive layer 22 may be compressed so that the pressure sensing component 40 can be pushed against the abutment portion 121 of the inner wall 12 by the compression rebound force of the adhesive backing. This can not only improve the stability of the key module 1, but also enable the pressure sensing component 40 to better abut against the inner wall 12. The compression rebound force of the adhesive backing can be adjusted by adjusting the adhesive backing material, adhesive backing area, and adhesive backing interference amount. In other words, in the direction from the inner wall 12 to the outer wall 13, this embodiment can make the key module 1 and the mounting groove 10 have an interference fit.

[0062] Optionally, the first positioning rib 24 is extended along the height direction of the first fixing portion 21, and the height of the first fixing portion 21 and the first positioning rib 24 is greater than the height of the button 50, and the opposite ends of the first positioning rib 24 protrude from the button 50. Since the opposite ends of the button 50 are connected to the opposite ends of the elastic member 30 when the button 50 is installed, the button 50 will cover the first fixing portion 21 in the length direction, but in this embodiment, the height of the first fixing portion 21 and the height of the first positioning rib 24 are greater than the height of the button 50, so that the two ends of the first positioning rib 24 can be exposed and abut against the outer side walls 13 on the upper and lower sides of the mounting hole 11, thereby achieving the above-mentioned extrusion effect.

[0063] Please refer to Figure 11-Figure 12 , Fig.12 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, the bracket 20 further includes a bracket body 25 connected to the first fixing portion 21, and two second fixing portions 26 connected to opposite ends of the bracket body 25, the two second fixing portions 26 are disposed 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.

[0064] In addition to the first fixing portion 21, the bracket 20 may also include a bracket body 25 and two second positioning portions 32. 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.

[0065] 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 installation groove 10 in a direction perpendicular to the inner wall 12 and the outer wall 13. When the bracket 20 is installed in the installation groove 10, the buckle positions 250 can be set in the buckle groove 14. By setting a reasonable buckling amount, the second fixing part 26 can be prevented from loosening or falling after the fixed connection with the installation groove 10 fails, resulting in poor waterproofing.

[0066] In this embodiment, a positioning groove 15 is further provided on the bottom wall of the installation groove 10. When the bracket 20 is installed in the installation groove 10, the first fixing portion 21 can be disposed in the positioning groove 15, thereby achieving the positioning installation of the bracket 20 and improving the position accuracy of the bracket 20 during installation.

[0067] Please refer to Fig.11 , Figure 13-14 , Fig.13 for Fig.11 A schematic diagram of the three-dimensional structure of the bracket shown in another perspective. Fig.14 for Figure 8 The illustrated partial enlarged view of the key module when it is installed in 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 second positioning rib 261 and a third positioning rib 262 on opposite sides thereof, the second positioning rib 261 abuts against the outer side wall 13, and the third positioning rib 262 abuts against the inner side wall 12, and along the arrangement direction of the two second fixing portions 26, the second positioning rib 261 and the third positioning rib 262 are staggered.

[0068] On the basis that the bracket 20 includes the second fixing portion 26, a second positioning rib 261 and a third positioning rib 262 may be provided on opposite sides of the second fixing portion 26, that is, a second positioning rib 261 is provided on a side of the second fixing portion 26 close to the outer wall 13, for example, each second fixing portion 26 is provided with a second positioning rib 261, and the second positioning rib 261 is provided at an end of the second fixing portion 26 close to the first fixing portion 21. A third positioning rib 262 is provided on a side of the second fixing portion 26 close to the inner wall 12, for example, each second fixing portion 26 is provided with a third positioning rib 262, and the third positioning rib 262 is provided at an end of the second fixing portion 26 away from the first fixing portion 21. When the bracket 20 is installed in the mounting groove 10, the second positioning rib 261 may abut against the outer wall 13, and the third positioning rib 262 may abut against the inner wall 12. The second positioning rib 261 and the third positioning rib 262 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 second positioning rib 261 and the third positioning rib 262 can enable the bracket 20 to be interference-fitted with the mounting slot 10 .

[0069] In addition, along the arrangement direction of the two second fixing portions 26, the second positioning rib 261 and the third positioning rib 262 are staggered. For example, the second positioning rib 261 mentioned above is arranged at one end of the second fixing portion 26 close to the first fixing portion 21, and the third positioning rib 262 is arranged at one end of the second fixing portion 26 away from the first fixing portion 21. By staggering the second positioning rib 261 and the third positioning rib 262, it can be ensured that when the size of the bracket 20 and / or the installation groove 10 fluctuates, the amount of compression 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 second positioning rib 261 and the third positioning rib 262 can be bent and deformed to a certain extent, so that the bracket 20 can be installed in the installation groove 10.

[0070] Please refer again Fig. 9 and Fig.11 In 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.

[0071] 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, and 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.

[0072] In summary, the button module 1 provided in this embodiment can achieve IPX8 waterproof performance, where 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.

[0073] Please refer again Figure 1-Figure 5 , Fig.13 ,as well as Fig.15 , Fig.15 for Figure 7 The key module 1 is a partial cross-sectional schematic diagram along another direction when it is installed in the shell. In this embodiment, the inner side wall 12 is provided with a glue overflow groove 123 at the opening of the installation groove 10, and the pressure sensing member 40 includes a pressure sensing portion 43 fixed to the elastic member 30 away from the first fixed portion 21, and a first extension portion 44 connected to the pressure sensing portion 43 and extending along the thickness direction of the shell 2, the first extension portion 44 extends to the outside of the installation 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 installation 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.

[0074] The top of the inner wall 12, i.e., the inner wall 12 near the opening of the mounting groove 10, can be provided with a glue overflow groove 123. The pressure sensing element 40 includes a pressure sensing portion 43 and a first extension portion 44. The pressure sensing portion 43 is the portion fixed to the elastic member 30 mentioned above. The first extension portion 44 can 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 can be provided corresponding to the glue overflow groove 123. For example, the pressure sensing element 40 includes two first extension portions 44, and two glue overflow grooves 123 are also provided, and each first extension portion 44 corresponds to one glue overflow groove 123.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] Please refer to Figure 1-Figure 3 ,as well as Fig.16 , Fig.16 for Figure 7 The 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.

[0081] Please refer to Figure 1-Figure 3 ,as well as Figure 16-Figure 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.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 key module is installed in the shell from another perspective without the third seal. 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 250 are provided on opposite sides of the through hole 16, and the bracket buckles 250 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 250 and the hanging foot structure 72 to prevent the bracket 20 from falling.

[0082] 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 .

[0083] Optionally, a groove 19 is provided on the other side of the housing 2, and the foot structure 72 can be snapped onto the bottom wall of the groove 19. 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.

[0084] Please refer to Fig.15 and Fig.21 , Fig.21 Schematic diagram of the three-dimensional structure of a key in an embodiment of the present application.

[0085] 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 disposed on the outer peripheral side of the key body 52, 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 disposed 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.

[0086] 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.

[0089] 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.

[0090] 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, and then the above components can be installed in 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.

[0091] 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.
