For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0026] Please refer to Figures 1 to 4The lateral key waterproof structure of the preferred embodiment of the present application comprises a shell 10, a key 20 arranged on the shell 10, and an elastic sealing member 30 mounted on the shell 10. The shell 10 can be a square structure, a circular structure, or other structures, which are not limited herein. The shell 10 is internally provided with a control panel 40 and a mechanical switch 50 arranged on the control panel 40. An assembly hole 12 is formed on a side wall 11 of the shell 10. In the embodiment, the assembly hole 12 is substantially circular in shape. In other embodiments, the assembly hole 12 can be square or other structures according to the structure of the key 20. The key 20 is at least partially inserted into the assembly hole 12 and can move along the axial direction of the key 20 relative to the shell 10. A stop structure is arranged between the key 20 and the shell 10 to limit the key 20 from moving outwardly out of the shell 10 and to limit the excessive movement of the key 20. The elastic sealing member 30 is mounted on the inner side of the side wall 11. The elastic sealing member 30 has a first surface 31 facing the side wall 11 and a second surface 32 arranged away from the side wall 11. The outer edge portion of the first surface 31 is attached to the side wall 11. In the axial direction of the key 20, the projection of the first surface 31 blocks the assembly hole 12. The first surface 31 is recessed inwardly to form a receiving groove 33 toward the second surface 32. The key 20 is partially inserted into the receiving groove 33. The second surface 32 applies a force to the mechanical switch 50 when the elastic sealing member 30 is deformed by the key 20.
[0027] The lateral key waterproof structure of the present application sets the key 20 in the assembly hole 12 of the shell 10 and mounts the elastic sealing member 30 on the inner side of the side wall 11, with the outer edge portion of the elastic sealing member 30 attached to the side wall 11 and blocking the assembly hole 12 in the axial direction. In this way, the key 20 and the assembly hole 12 are located on the outer side of the elastic sealing member 30. The elastic sealing member 30 separates the inside and outside of the shell 10 to prevent water from entering the inside of the shell 10 from the outside. The elastic property of the elastic sealing member 30 allows the key 20 to apply a force to the mechanical switch 50 when the key 20 is pushed inwardly to be deformed, thereby starting the mechanical switch 50. After the external force is removed, the elastic sealing member 30 drives the key 20 to return to the original position. Compared with the prior art, the lateral key waterproof structure of the present application achieves waterproofing while only using the assembly hole 12 formed on the shell 10 and the key 20 and the elastic sealing member 30. The number of parts is small, the structure is simple, the assembly is convenient, the cost is reduced, and the assembly space required is small.
[0028] In addition, the key 20 and the elastic sealing member 30 in the present application are two independent components. The relative positions between the key 20 and the elastic sealing member 30 and the shell 10 are limited by using the stop structure, thereby eliminating the need to use double-color molding or dispensing to fix the key 20 on the elastic sealing member 30, which helps to reduce the process and cost.
[0029] The button 20 moves in the axial direction to form a first position and a second position. When the button 20 is in the first position, Figure 1 In the position shown, the button 20 does not apply a force to the elastic seal 30, the mechanical switch 50 is not subjected to a force, is not activated, or the mechanical switch 50 is in the first state; when the button 20 is subjected to an external force, the button 20 moves axially toward the inside of the housing 10, and the button 20 is converted from the first position to the second position. The button 20 applies a force to the elastic seal 30 in the axial direction, and the elastic seal 30 is deformed in the axial direction and stretched toward the inside of the housing 10. At this time, the force on the elastic seal 30 is transmitted to the mechanical switch 50, applying a force to the mechanical switch 50, and the mechanical switch 50 is activated or the mechanical switch 50 is converted from the first state to the second state; when the force on the button 20 is removed, the button 20 moves toward the outside of the housing 10 under the action of the rebound force of the elastic seal 30 until the button 20 is stopped by the stop structure and can no longer move outward, and the button 20 is converted from the second position to the first position. At this time, the mechanical switch 50 is in the disconnected state or remains in the second state. It should be noted that the mechanical switch 50 can be a mechanical structure that is in an on state when an external force is applied and is in an off state when the external force is removed, or it can be a mechanical structure that switches between a first state and a second state when an external force is applied, the first state being on and the second state being off.
[0030] To facilitate assembly of the key 20 and limit its transitional displacement, a stop structure is formed on the key 20 in this embodiment. Specifically, the key 20 comprises a key portion 21 and a rod portion 22 extending rearwardly from the key portion 21. The key portion 21 is located outside the assembly hole 12. The rod portion 22 passes through the assembly hole 12 and extends into the receiving groove 33. The stop structure is a hook portion 23 formed on the rod portion 22. There are two rod portions 22, which are arranged opposite each other with a gap 24 between them. The total dimension of the two rod portions 22 plus the gap 24 is slightly larger than the dimension of the assembly hole 12. The inner hook surface (not numbered) of the hook portion 23 is flat. In the first position, the inner hook surface abuts the inner surface of the side wall 11. In the second position, the hook portion 23 is separated from the inner surface, with a distance between them that corresponds to the movement distance of the key 20. To limit the inward movement of the button 20 and prevent excessive inward displacement of the button 20 from damaging the mechanical switch 50, a first mounting groove 13 is recessed on the outer surface of the side wall 11. The button portion 21 is at least partially accommodated in the first mounting groove 13. The first mounting groove 13 also limits the circumferential movement of the button 20, ensuring smooth movement of the button 20.
[0031] In the embodiment, the second assembly groove 14 is recessed on the inner side of the side wall 11 of the shell 10, and the elastic sealing member 30 is at least partially located in the second assembly groove 14, so as to facilitate the installation and fixation of the elastic sealing member 30. The elastic sealing member 30 is made of silica gel, and the lateral key waterproof structure of the application can ensure the waterproof requirement of more than 4 levels. The elastic sealing member 30 is generally in the form of a frame with a wide frame body structure.
[0032] In the embodiment, the elastic sealing member 30 always abuts against the key 20 in the axial direction in the first position and the second position, and the mechanical switch 50 always abuts against the elastic sealing member 30 in the axial direction in the first position and the second position, so as to ensure the pressing feeling. Of course, in other embodiments, a gap 24 of about 0.1 mm can be provided between the key 20 and the elastic sealing member 30.
[0033] In order to ensure the pressing feeling and improve the effectiveness of the force, the elastic sealing member 30 is provided with a hard abutting member 60, and the elastic sealing member 30 abuts against the mechanical switch 50 in the axial direction through the hard abutting member 60. In the embodiment, the hard abutting member 60 is a PET sheet, which is adhered to the elastic sealing member 30. In order to facilitate the connection between the PET sheet and the mechanical switch 50, the PET sheet is recessed to form an opening groove for inserting the mechanical switch 50.
[0034] The technical features of the above-described embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.
[0035] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as the limitation of the scope of the present application. It should be pointed out that, for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
