[0040] The following will be described in detail in combination with specific drawings and examples:

[0041] Please refer to Figure 1 and Figure 2The key structure comprises a housing 10, a key assembly 20, a sealing member 30 and a pressing member 40. The key assembly 20 is arranged in the housing 10. The sealing member 30 comprises a pressing portion 31 and a sealing portion 32, and the sealing portion 32 is connected to the outer periphery of the pressing portion 31. The pressing portion 31 is movable relative to the sealing portion 32. The pressing portion 31 is oppositely arranged with the key assembly 20 along a first direction Y. The housing 10 is internally provided with a sealing groove 11, and the sealing groove 11 is annularly arranged on the outer periphery of the pressing portion 31. The sealing portion 32 is assembled in the sealing groove 11. The pressing member 40 is movably arranged on the housing 10 along at least the first direction Y. Meanwhile, the pressing member 40 is also connected to the side of the pressing portion 31 away from the key assembly 20, and is used to drive the pressing portion 31 to trigger the key assembly 20 under the action of an external force.

[0042] The key assembly 20 comprises a key 21 and a circuit board assembly 22. The key 21 is oppositely arranged with the pressing portion 31 along the first direction Y for being pressed and triggered by the pressing portion 31. The circuit board assembly 22 is electrically connected to the key 21, and is also used to be electrically connected to the mainboard, power supply and other components on the electronic device, so that the key 21 can realize the switching of the related circuit in the electronic device through the circuit board assembly 22 when being triggered.

[0043] The sealing member 30 refers to a material member with sealing effect. In the embodiment of the present application, the sealing member 30 can prevent as much as possible the invasion of dust, moisture and the like from the outside into the key assembly 20 in the housing 10.

[0044] The oppositely arranged pressing portion 31 and the key assembly 20 along the first direction Y means that along the first direction Y, the projection of the pressing portion 31 and the projection of the part of the key assembly 20 for being pressed and triggered are at least partially overlapped.

[0045] The pressing portion 31 can be abutted to one side of the key assembly 20 along the first direction Y, so that when the pressing member 40 drives the pressing portion 31 to move towards the key assembly 20, the pressing portion 31 can press and trigger the key assembly 20. Alternatively, the pressing portion 31 can also be spaced apart from and oppositely arranged with the key assembly 20 along the first direction Y, so that when the pressing member 40 drives the pressing portion 31 to move, the pressing portion 31 can first approach the key assembly 20, and then move to abut against the key assembly 20 to press and trigger the key assembly 20.

[0046] The pressing member 40 and the pressing portion 31 can be fixedly connected through clamping, bolt connection and the like, so that the pressing member 40 is not easy to be separated from the pressing portion 31 when driving the pressing portion 31 to move.

[0047] The pressing portion 31 can be a columnar structure, so as to better bear the pressure from the pressing member 40, and also to better abut against the key assembly 20. Of course, the pressing portion 31 can also be other shapes, which are not limited herein.

[0048] It can be understood that when the sealing part 32 is assembled in the sealing groove 11, the sealing member 30 is arranged to tightly fit the inner groove wall of the sealing groove 11, so that external moisture is difficult to enter the shell 10 through the gap between the sealing member 30 and the inner groove wall of the sealing groove 11, thereby waterproofing the key assembly 20.

[0049] The key structure provided by the embodiments of the present application is that the sealing member 30 is not a simple sealing ring, but includes two parts of the pressing part 31 and the sealing part 32, wherein the pressing part 31 is connected to the pressing piece 40, and the sealing part 32 is sealingly matched with the sealing groove 11. When the pressing piece 40 is pressed by external force, the pressing part 31 can move relative to the sealing part 32 under the driving of the pressing piece 40, while the sealing part 32 still maintains the state of sealingly matching with the sealing groove 11. In this way, the sealing part 32 of the sealing member 30 is not easy to be displaced relative to the shell 10, and is not easy to be deformed by friction during movement, so that the sealing member 30 still has good sealing effect after long-term use.

[0050] In some embodiments, referring to Figure 2 and Figure 3 , the sealing groove 11 has a first inner groove wall 111 and a second inner groove wall 112, and the first inner groove wall 111 and the second inner groove wall 112 are oppositely arranged along the first direction Y. The sealing groove 11 is also provided with a third inner groove wall 113 and a fourth inner groove wall 114, and the third inner groove wall 113 and the fourth inner groove wall 114 are oppositely arranged along the radial direction of the sealing groove 11. A gap 115 is arranged between the first inner groove wall 111 and the third inner groove wall 113. The sealing part 32 abuts against the first inner groove wall 111, the second inner groove wall 112, the third inner groove wall 113 and the fourth inner groove wall 114.

[0051] It can be understood that along the first direction Y, the sealing part 32 is limited between the first inner groove wall 111 and the second inner groove wall 112 of the sealing groove 11, and the opposite sides of the sealing part 32 along the first direction Y abut against the first inner groove wall 111 and the second inner groove wall 112, respectively. Along the radial direction of the sealing groove 11, the sealing part 32 is limited between the third inner groove wall 113 and the fourth inner groove wall 114 of the sealing groove 11, and the inner and outer circumferential walls on the opposite sides of the sealing part 32 along the radial direction of the sealing groove 11 abut against the third inner groove wall 113 and the fourth inner groove wall 114, respectively.

[0052] The gap 115 is used for connecting the part of the sealing member 30 other than the sealing part 32 with the sealing part 32. The sealing part 32 can also seal the gap 115 to further improve the sealing effect between the sealing part 32 and the sealing groove 11.

[0053] In this way, the opposite ends of the sealing part 32 along the first direction Y are limited and abutted by the first inner groove wall 111 and the second inner groove wall 112 of the sealing groove 11, and the inner peripheral wall and the outer peripheral wall of the sealing part 32 along the radial direction of the sealing groove 11 are also limited and abutted by the third inner groove wall 113 and the fourth inner groove wall 114, so that the sealing member 30 is not easily displaced relative to the outer shell 10 during the movement of the pressing part 31 driven by the pressing member 40, thereby reducing the mutual friction between the sealing member 30 and the outer shell 10, preventing the sealing member 30 from being deformed, and improving the waterproof sealing effect of the key structure.

[0054] In some embodiments, referring to Figure 2 and Figure 3 , the sealing member 30 further comprises a connecting part 33 connected between the outer periphery of the pressing part 31 and the inner periphery of the sealing part 32. The connecting part 33 is arranged opposite to the pressing member 40 along the first direction Y. The connecting part 33 is also arranged opposite to the key assembly 20 along the first direction Y. The connecting part 33 is provided through the gap 115.

[0055] Along the first direction Y, the projection of the connecting part 33 and the projection of the part of the key assembly 20 to be pressed and triggered are at least partially overlapped, and the projection of the connecting part 33 and the projection of the pressing member 40 are at least partially overlapped.

[0056] In one possible design, the connecting part 33 is elastic. When the pressing member 40 drives the pressing part 31 to move, the pressing part 31 moves along the first direction Y, and the connecting part 33 connected thereto is driven along the first direction Y, and the connecting part 33 is deformed and elongated along the first direction Y to accumulate elastic potential energy. Then, after the external force on the pressing member 40 is removed, the connecting part 33 releases the elastic potential energy and drives the pressing part 31 to move away from the key assembly 20 along the first direction Y.

[0057] It can be understood that the pressing part 31, the connecting part 33 and the sealing part 32 together realize the sealing effect of the key assembly 20 in the outer shell 10.

[0058] By providing the connecting part 33, when the pressing member 40 drives the pressing part 31, the connecting part 33 can also be driven by the pressing member 40 to drive the pressing part 31 to move along the first direction Y to approach the key assembly 20, and the connecting part 33 can also drive the pressing part 31 to move away from the key assembly 20, without the user manually driving the pressing member 40 to move away from the key assembly 20, thereby improving the driving efficiency of the pressing member 40 on the pressing part 31.

[0059] In some embodiments, referring to Figure 3 , the size of the connecting portion 33 in the first direction Y is smaller than the size of the sealing portion 32 in the first direction Y.

[0060] As an example, the first direction Y is as shown in the direction Y in Figure 3 . In actual use, the first direction Y is approximately the thickness direction of the sealing portion 32 and the connecting portion 33 in the installed state.

[0061] In this way, the connecting portion 33 is more easily deformed along the first direction Y, so that the connecting portion 33 does not hinder the movement of the pressing portion 31 while connecting the sealing portion 32 and the pressing portion 31, reducing the resistance of the pressing member 40 during pressing use. The size of the sealing portion 32 in the first direction Y is relatively large, so that the sealing portion 32 can better abut against the inner wall of the sealing groove 11, thereby improving the sealing effect between the sealing portion 32 and the sealing groove 11.

[0062] In some embodiments, referring to Figure 2 to Figure 5 , the housing 10 includes a first shell 12, a second shell 13, and a pressing member 14. The key assembly 20 is arranged in the space formed by the first shell 12 and the second shell 13. The pressing member 14 includes a first pressing portion 141 and a second pressing portion 142. The first pressing portion 141 is provided with a avoiding slot 1411 along the first direction Y. The second pressing portion 142 is connected to the outer periphery of the first pressing portion 141. The pressing portion 31 is arranged in the avoiding slot 1411 along the first direction Y. The second pressing portion 142 is pressed between the first shell 12 and the second shell 13 along the first direction Y. The first inner groove wall 111 and the fourth inner groove wall 114 are both arranged on the first shell 12. The second inner groove wall 112 is arranged on the side of the second pressing portion 142 close to the first shell 12 along the first direction Y. The third inner groove wall 113 is arranged on the outer periphery side of the first pressing portion 141.

[0063] The first shell 12 and the second shell 13 can be connected to each other by screwing, clamping, riveting, etc., so that the first shell 12 and the second shell 13 are easy to disassemble and assemble. Compared with the existing bonding connection mode, the first shell 12 and the second shell 13 of the present application are fixed by mechanical connection, which is more stable and has a longer service life.

[0064] Along the first direction Y, the second pressing portion 142 of the pressing member 14 can be limited and pressed tightly by the first shell 12 and the second shell 13 along the first direction Y, so that the pressing member 14 can be stably installed between the first shell 12 and the second shell 13.

[0065] It can be understood that, as Figure 3As shown, the first pressing part 141, the second pressing part 142 and the first shell 12 jointly enclose the sealing groove 11, and the sealing element 30 is located between the second pressing part 142 and the first shell 12 along the first direction Y and is located between the first pressing part 141 and the first shell 12 along the radial direction of the sealing groove 11.

[0066] The pressing element 14 and the first shell 12 enclose the sealing groove 11, and only the connection between the second shell 13 and the first shell 12 needs to be disassembled, and then the pressing element 14 is removed to take out the sealing element 30, thereby improving the convenience of replacing and maintaining the sealing element 30. The material of the pressing element 14 can be selected according to the actual needs of the user, so that the user can change the pressure when the sealing element 30 and the pressing element 14 are pressed by changing the material of the pressing element 14, which is simple to operate and has good sealing performance.

[0067] In some embodiments, at least one of the sealing element 30 and the pressing element 14 is a rubber element, or at least one of the sealing element 30 and the pressing element 14 is a silica gel element.

[0068] The rubber element and the silica gel element have good elastic properties and can elastically deform under external force, so that the sealing element 30 can better fit the inner wall of the sealing groove 11, thereby improving the sealing effect of the sealing element 30 and improving the pressing feeling when the pressing element 40 presses the pressing part 31. Along the first direction Y and the radial direction of the sealing groove 11, the pressing element 14 can be elastically pressed on the sealing element 30 by the elastic properties of the pressing element 14, thereby improving the sealing between the pressing element 14 and the sealing element 30. At the same time, the rubber element and the silica gel element have good wear resistance and bending resistance, and can resist a certain degree of pressure and impact, so that the sealing element 30 and the pressing element 14 are not easily damaged under external force, thereby prolonging the service life of the key structure.

[0069] In some embodiments, referring to Figure 2 to Figure 4 The pressing element 40 includes a pressing body 41 and a limiting structure 42. The pressing body 41 is movably arranged on the outer shell 10 along at least the first direction Y. The pressing body 41 is connected to the side of the pressing part 31 away from the key assembly 20 and is used to drive the pressing part 31 to trigger the key assembly 20 under the action of external force. The limiting structure 42 is arranged on the pressing body 41. The limiting structure 42 is used to limit the outer shell 10 to limit the movement stroke of the pressing body 41 away from the key assembly 20 along the first direction Y.

[0070] Since the pressing body 41 is subjected to external force, the side of the pressing body 41 away from the key assembly 20 can be provided with a larger area to facilitate the user to press better.

[0071] In a possible design, the limiting structure 42 can be a buckle structure arranged on the pressing body 41, and the shell 10 is provided with a clamping groove matched with the limiting structure 42. When the limiting structure 42 moves towards the key assembly 20 along with the pressing body 41, the buckle is disengaged from the clamping groove. During the movement of the limiting structure 42 away from the key assembly 20 along with the pressing body 41, the buckle can be clamped in the clamping groove on the shell 10, so that the pressing body 41 cannot continue to move away from the key assembly 20. Of course, the limiting structure 42 can also be a magnetic piece, and the shell 10 is provided with a magnetic piece matched with the limiting structure 42. When the limiting structure 42 moves towards the key assembly 20 along with the pressing body 41, the magnetic attraction is disconnected. During the movement of the limiting structure 42 away from the key assembly 20 along with the pressing body 41, the two magnetic pieces are attracted to each other, so that the pressing body 41 cannot continue to move away from the key assembly 20. The setting form of the limiting structure 42 is not limited to the above two forms, and can also be other forms, which will not be described here.

[0072] In this way, when the pressing body 41 is pressed, the pressing body 41 can drive the pressing part 31 to trigger the key assembly 20. When the external force is removed from the pressing body 41, the pressing body 41 will not be removed from the shell 10, which improves the installation stability of the pressing body 41 on the shell 10 and is beneficial to maintaining the working state of the reciprocating pressing of the pressing body 41 on the pressing part 31.

[0073] In some embodiments, the shell 10 includes a first wall 15. The first wall 15 is arranged opposite to the sealing piece 30 along a first direction Y. The first wall 15 is provided with a first through hole 151 and a second through hole 152 along the first direction Y, and the first through hole 151 and the second through hole 152 are arranged at intervals on the first wall 15. The pressing body 41 includes a first through hole part 411 and an operation part 412. The operation part 412 is arranged on a side of the first wall 15 away from the key assembly 20. The operation part 412 is used for being pressed by a user. The first through hole part 411 is arranged through the first through hole 151 and is connected to a side of the pressing part 31 away from the key assembly 20. The limiting structure 42 is arranged through the second through hole 152. The limiting structure 42 is used for limiting a side of the first wall 15 close to the key assembly 20 along the first direction Y.

[0074] The side of the operation part 412 away from the key assembly 20 can be arranged to have a large area, so that the pressing body 41 can be better stressed when being pressed.

[0075] The first through hole part 411 can be cylindrical, quadrangular prism or the like, which can be designed according to the shape of the first through hole 151, and is not limited here.

[0076] As an example, as shown in FIG. 6, the first through hole part 411 is cylindrical. Figure 4As shown, the limiting structure 42 may include a hook portion 421 and a second through-hole portion 422. The second through-hole portion 422 can pass through the second through-hole 152. When moving with the pressing body 41, the hook portion 421 can abut against the outer peripheral wall of the second through-hole 152 along the side wall of the first wall 15 near the button assembly 20, so as to achieve the limiting effect on the pressing body 41. The hook portion 421 and the operating portion 412 are arranged at intervals along the first direction Y. When driving the pressing body 41 to move closer to the button assembly 20, the operating portion 412 can abut against the side of the first wall 15 away from the button assembly 20. When the pressing body 41 moves away from the button assembly 20, the hook portion 421 can abut against the side of the first wall 15 near the button assembly 20. Thus, the operating part 412 and the hook part 421 can respectively limit the maximum stroke of the pressing body 41 in the pressing and resetting processes, so that the user can design the distance between the hook part 421 and the operating part 412 along the first direction Y according to the actual situation, so as to adjust the movement stroke of the pressing body 41 along the first direction Y.

[0077] When the user applies force to the pressing body 41, the pressing body 41 drives the pressing part 31 to press the button assembly 20, triggering the button assembly 20. At this time, the limiting structure 42 can move with the pressing body 41 toward the button assembly 20. Then, the pressing body 41 is driven away from the button assembly 20, causing the pressing part 31 to move away from the button assembly 20, and the button assembly 20 returns to its untriggered state. At this time, the limiting structure 42 can move with the pressing body 41 away from the button assembly 20, and after moving a certain distance, it can abut against the side of the first wall 15 along the first direction Y that is close to the button assembly 20, thereby preventing the pressing body 41 from moving further away from the button assembly 20.

[0078] The limiting structure 42 is easy to manufacture and has a simple limiting fit with the first wall 15. When the pressing body 41 moves away from the button assembly 20, the setting of the limiting structure 42 ensures that the pressing body 41 will not detach from the outer shell 10, which improves the installation stability of the pressing body 41 on the outer shell 10 and is conducive to the reciprocating drive of the pressing part 31 by the pressing body 41.

[0079] In some embodiments, the pressing member 40 includes a plurality of limiting structures 42, and a plurality of second through holes 152. The plurality of second through holes 152 surround the outer periphery of the first through hole portion 411. Each limiting structure 42 passes through each second through hole 152.

[0080] As an example, such as Figure 4 and Figure 5As shown, the number of the limiting structures 42 can be set as two, and the two limiting structures 42 are spaced around the outer periphery of the first perforated portion 411, so that the two limiting structures 42 are spaced from each other along the second direction X. Of course, in some other embodiments, the limiting structures 42 can also be set as other numbers, which are not limited herein.

[0081] The first direction Y is as shown in the direction Y in the figure, and the second direction X is as shown in the direction X in the figure. Figure 5 The first direction Y is as shown in the direction Y in the figure, and the second direction X is as shown in the direction X in the figure. Figure 5 The first direction Y is as shown in the direction Y in the figure, and the second direction X is as shown in the direction X in the figure. Figure 5 The first direction Y is as shown in the direction Y in the figure, and the second direction X is as shown in the direction X in the figure.

[0082] In this way, the pressing piece 40 can be more stably and reliably installed on the first wall 15, and the movement stability of the pressing piece 40 during the reciprocating movement of the driving pressing portion 31 is improved.

[0083] The electronic device according to the second aspect of the present application comprises the key structure according to the first aspect of the present application.

[0084] The key structure according to the embodiments of the present application is the same as the key structure according to the above embodiments, and the related description in the above can be referred to, which will not be repeated here.

[0085] The key structure can control the opening and closing of the related circuit of the electronic device. The electronic device can be a tablet computer, a mobile phone, a television, a watch, etc.

[0086] The key assembly 20 comprises a key 21 and a circuit board assembly 22, and the circuit board assembly 22 is electrically connected to the key 21. The circuit board assembly 22 is also electrically connected to the mainboard, power supply and other components of the electronic device, so that when the key 21 is triggered, the key 21 can realize the switching operation of the related circuit in the electronic device through the circuit board assembly 22.

[0087] The electronic device provided by the embodiments of the present application comprises a pressing portion 31 and a sealing portion 32, wherein the pressing portion 31 is connected to the pressing piece 40, and the sealing portion 32 is in sealing cooperation with the sealing groove 11. When the pressing piece 40 is pressed by an external force, the pressing portion 31 can move relative to the sealing portion 32 under the driving of the pressing piece 40, and the sealing portion 32 still maintains the state of sealing cooperation with the sealing groove 11. In this way, the sealing portion 32 of the sealing member 30 is not easy to be displaced relative to the shell 10, and is not easy to be deformed due to friction during movement, so that the sealing member 30 still has a good sealing effect after long-term use, and the waterproof protection effect of the related circuit in the electronic device is improved.

[0088] The above merely provides preferred embodiments of the present application, and is not used to limit the present application. Any modification, equivalent replacement, and improvement made in the spirit and principle of the present application shall be included in the protection scope of the present application.
