At least part of the key cap 21 protrudes out of the notch of the key pressing groove 11, so that the pressing hand feeling of a user is improved, and the key pressing difficulty is reduced. In practical application, because the aperture of the key hole 12 is smaller than the inner diameter of the key slot 11, on one hand, the contact area between the user and the key cap 21 when the user presses the key cap 21 can be increased by increasing the outer size of the key cap 21, and the pressing hand feeling is improved; on the other hand can be through reducing the size of key hole 12 to make the external diameter of push rod 22 and the aperture looks adaptation of key hole 12, thereby can further reduce the waterproof degree of difficulty of key hole 12 department through reducing the clearance size between key hole 12 and the push rod 22, promote the waterproof performance of key hole 12 department.

It can be understood that the aperture of the key hole 12 is matched with the outer diameter of the push rod 22, that is, the aperture of the key hole 12 is usually slightly larger than the outer diameter of the push rod 22, and on the premise that the push rod 22 can move flexibly in the key hole 12, the gap between the key hole 12 and the push rod 22 is reduced as much as possible.

In the embodiment of the present application, the dredging structure 201 is disposed on the key cap 21, and can extend to the position where the key cap 21 protrudes out of the notch of the key groove 11, so that impurities such as water and dust can be more conveniently discharged out of the key groove 11.

It can be understood that, on the outer surface of the key cap 21 protruding out of the notch of the key slot 11, a roughened structure may be further provided to increase the friction between the key cap 21 and the finger of the user, thereby further reducing the difficulty of the key 20.

In the embodiment of the present application, a part of the elastic sealing element 30 may be sleeved on the push rod 22, and another part of the elastic sealing element 30 is sleeved on the key cap 21, so that the elastic sealing element 30 can play a role of waterproof sealing at the key hole 12, and can also play a role of protecting the detachable connection between the key cap 21 and the push rod 22. Specifically, one end of the elastic sealing element 30 abuts against the key cap 21, and the other end abuts against the groove bottom on the peripheral side of the key hole 12, which is equivalent to that the elastic sealing element 30 surrounds the peripheral direction of the key hole 12, so that the sealing and waterproof effects of the elastic sealing element 30 can be further improved.

In the embodiment of the present application, the key cap 21 and the push rod 22 can be detachably connected in various ways, for example, by a threaded connection, a magnetic adsorption connection, an adhesive, a snap connection, a fastener connection, and the like. In some embodiments, in order to improve the connection reliability between the key cap 21 and the push rod 22 and avoid the problem of loosening between the key cap 21 and the push rod 22, the key cap 21 and the push rod 22 may be connected by a screw thread, and the end surfaces of the key cap 21, which are in contact with the push rod 22, are connected by adhesion. Specifically, a threaded hole is formed in either the key cap 21 or the push rod 22, and a thread matched with the threaded hole is formed in the other one of the key cap 21 and the push rod 22, and the key cap 21 and the push rod 22 are detachably connected through the threaded hinge of the threaded hole and the threaded hole. In practical application, in order to avoid the problem of looseness of the threaded connection, the threaded part where the key cap 21 and the push rod 22 are in contact with each other and the end face position where the key cap and the push rod are in contact with each other can be bonded and connected through the adhesive 50 on the basis of the threaded connection. In this embodiment of the application, the adhesive 50 may be a double-sided adhesive, a thermosetting adhesive, a structural adhesive, or the like, and a person skilled in the art may select the adhesive according to actual situations, which is not limited in this embodiment of the application.

In the embodiment of the present application, a plug 221 is disposed at one end of the push rod 22 close to the function switch 21, and an outer diameter of the plug 221 is larger than an aperture of the key hole 12; one end of the plug 221 abuts against the function switch 21, and the other end abuts against the housing 10. In practical application, through setting up the top 221 at the one end of push rod 22, on the one hand can increase the area of contact of push rod 22 and function switch 21 through top 221, make the reliability that push rod 22 triggered function switch 21 higher, on the other hand can also play spacing effect to push rod 22 on casing 10 through top 221 butt, just so can avoid using the fixed bolster to the fixed of button 20, reduced the processing and the assembly degree of difficulty of button 20, reduced the cost of button 20.

In the embodiment of the present application, the push rod 22 and the plug 221 may be integrally formed, or may be detachably connected. The push rod 22 and the plug 221 may form a T-shaped structure. An embossing structure or the like may be further provided on an outer surface of the top 221 to increase friction force and facilitate assembly between the push rod 22 and the key cap 21.

In practical applications, the push rod 22 is matched with the key hole 12, the key hole 12 may be circular, square, diamond, etc., and the push rod 22 may also be a matched column structure. It will be appreciated that when the key hole 12 is a circular hole and the push rod 22 is a cylinder matching the circular hole, it is easier to machine and requires a smaller sealing area.

In this embodiment, the grooming structure 201 may specifically include: at least one of an arc surface, an arc protrusion and a groove. For example, the outer diameter of the key cap 21 increases gradually from the bottom of the key slot 11 to the opening of the key slot 11, so that the outer surface of the key cap 21 forms a smooth arc-shaped surface, and once liquid or other impurities enter the key slot 11, the liquid or the impurities can be smoothly discharged along the arc-shaped surface of the key cap 21 by manually shaking or applying flowing gas, thereby solving the problem that the liquid or the impurities are accumulated in the key slot 11 and are difficult to discharge. In the embodiment of the present application, the arc surface is a smooth arc surface, including but not limited to a spherical surface.

Referring to fig. 6, a schematic structural diagram of an elastic seal according to an embodiment of the present application is shown. In the embodiment of the present application, the elastic sealing member 30 elastically abuts on the groove bottom on the peripheral side of the key hole 12. In order to reduce the resistance when the user presses the key 20 and improve the pressing hand feeling, the elastic sealing element 30 extends towards the direction departing from the peripheral side of the key 20 along the direction from the notch of the key groove to the groove bottom and abuts against the groove bottom; in the case of the key 20 approaching the function switch 21, the key 20 drives the elastic sealing element 30 to approach the groove bottom and the contact area with the groove bottom increases, and in the case of the key 20 moving away from the function switch 21, the key 20 drives the elastic sealing element 30 to move away from the groove bottom and the contact area with the groove bottom decreases.

It can be understood that when the key 20 is close to the function switch 21, that is, when the user presses the key 20, the contact area between the elastic sealing element 30 and the groove bottom is increased, so as to improve the sealing reliability of the elastic sealing element 30, and when the key 20 is far from the function switch 21, that is, after the pressing is completed, and the key 20 automatically returns to the default initial position, the elastic sealing element 30 can also be elastically and self-restored under the driving of the key 20. In the embodiment of the present application, the elastic sealing member 30 is not limited to a silicone sealing ring, an annular foam pad, an annular sponge pad, etc.

In the embodiment of the present application, in order to improve the sealing performance between the elastic sealing element 30 and the key 20, an abutting portion 211 may be further disposed on the key 20; one end of the elastic sealing member 30 is provided with a first lip structure 31, and the first lip structure 31 abuts against the abutting portion 211. In practice, the lip structure may be understood as an extended wall extending circumferentially away from the key 20. The first lip structure 31 and the abutting portion 211 increase the contact area between the end face of the elastic sealing member 30 and the key 20, thereby improving the waterproof performance.

Alternatively, the abutment 211 may include: at least one of a platform, a boss and a groove. For example, when the abutting portion 211 is a boss, the first lip structure 31 may abut against the boss, and the boss may function as a limit on one hand, and on the other hand, may also function to increase the contact area between the key 20 and the first lip structure 31, thereby improving the waterproof performance thereof.

In the embodiment of the present application, in order to increase the contact area between the elastic sealing element 30 and the bottom of the groove and improve the waterproof performance at the key hole 12, the other end of the elastic sealing element 30 is provided with a second lip structure 32, and the second lip structure 32 abuts against the bottom of the groove on the side of the key hole 12. Specifically, the first lip structure 31 and the second lip structure 32 may be the same, so that the processing and assembling difficulty of the elastic sealing member 30 is reduced, especially, the problem of reverse assembling is not required to be considered during assembling, and the assembling efficiency can be improved.

In the embodiment of the present application, since the second lip structure 32 abuts against the bottom of the key groove 11 and is closer to the key hole 12, and higher sealing reliability is required, the size of the second lip structure 32 can be set to be larger than that of the first lip structure 31, so that the contact area between the second lip structure 32 and the bottom of the groove is larger, and the waterproof performance is higher.

In the present embodiment, the inner diameter of the elastic sealing member 30 increases in the direction from the first lip structure 31 to the second lip structure 32, and the elastic sealing member 30 forms a concave arc-shaped outer surface. As shown in fig. 6, the elastic sealing element 30 may be shaped like a horn, and the flared elastic sealing element 30 has an a end surface (end surface on the side of the large-diameter horn) and a b end surface (end surface on the side of the small-diameter horn), which are opposite to each other, wherein the a end surface abuts against the groove bottom on the periphery of the key hole 12, and the b end surface abuts against the key 20, when the key 20 is pressed, the a end surface and the b end surface are stressed, so that the a end surface and the key 20, and the b end surface and the groove bottom are attached more tightly, and the contact area is larger, thereby effectively blocking the liquid inlet path and improving the waterproof performance.

In the embodiment of the present application, the horn-shaped elastic sealing element 30 has the concave arc-shaped outer surface c, so that when the key 20 is not pressed, the liquid adheres to the c surface, which can make the fit between the elastic sealing element 30 and the key 20 tighter; when the key 20 is pressed, the elastic sealing element 30 is pressed, liquid flows out of the key groove 11 along the surface c more easily, and therefore accumulation of impurities such as water and dust in the key groove can be reduced.

In the embodiment of the present application, along the direction from the first lip edge structure 31 to the second lip edge structure 32, the inner diameter of the elastic sealing member 30 increases progressively, which can be understood as the direction from the first lip edge structure 31 to the second lip edge structure 32, the fit tightness between the elastic sealing member 30 and the key 20 decreases progressively in sequence, or at the second lip edge structure 32, a gap is formed between the elastic sealing member 30 and the key 20 in the circumferential direction, so that the pressing resistance of the elastic sealing member 30 to the key 20 can be reduced, and the pressing hand feeling of the key 20 is better.

In this embodiment of the application, in order to further improve the waterproof performance at the key hole 12, the electronic device may further include: a cushion seal 40; the buffering sealing member 40 is sleeved on one side of the key 20 extending into the casing 10, and one end of the buffering sealing member 40 abuts against the casing 10, and the other end abuts against the key 20. In the present embodiment, the cushion seal 40 includes, but is not limited to, a silicone gasket, an annular foam pad, and the like.

In the embodiment of the application, buffering sealing member 40 has the pre-compaction buffering function, one end elasticity butt through buffering sealing member 40 is on casing 10, other end elasticity butt is on button 20, can play the cushioning effect between button 20 and casing 10 on the one hand, avoid "hard" contact between button 20 and the casing 10, on the other hand can also play sealed waterproof effect, further seal up key hole 12 department in casing 10, promote the waterproof performance who presses key hole 12 department.
