Embodiment 1

[0031] Since the usual side key 3 is in the shape of a cuboid, the structure of the side key 3 and the elastic body 2 will be introduced below based on the cuboid side key 3 .

[0032] The side key 3 includes an annular side wall 31 and an end cap 32 disposed at one end of the annular side wall 31 . In this way, the structure of the side key 3 can be simplified, the manufacturing cost can be reduced, and it is convenient to attach the side key 3 to the elastic body 2 by glue. The connecting portion of the annular side wall 31 and the end cap 32 can be rounded or chamfered to reduce the possibility of scratches on the connecting portion of the annular side wall 31 and the end cap 32 . The annular side wall 31 and the end cover 32 can be integrally formed to facilitate manufacturing.

[0033] The main body of the elastic body 2 is roughly a plate-shaped structure, roughly rectangular. The material of the elastic body 2 may be TPU (Thermoplastic polyurethanes, thermoplastic pol...

Embodiment 2

[0041] The difference between the second embodiment and the first embodiment lies in that the inner wall of the casing is provided with an annular pressing plate for pressing the extension area, and the installation firmness of the annular pressing plate is relatively high. When installing the elastic body, the extension area is inserted under the annular pressure plate, and the elastic body is fixed by the annular pressure plate to realize the sealing between the elastic body and the housing.

Embodiment 3

[0043] The difference between the third embodiment and the first embodiment is that an annular pressure plate for pressing the extension area is provided on the inner wall of the casing. The elastic body is arranged on the inner wall of the housing through glue and pressed through the annular pressure plate.

[0044] In other embodiments, such as Figure 7 As shown, the boss 23 can also exceed the range covered by the annular side wall 31 of the side button 3, so as to improve the sensitivity when the side button 3 is pressed.

[0045] Regardless of the above-mentioned embodiment, the side key 3 of the side key waterproof device 200 can be a sound key or a power key. When it is a sound button, the sound increase button part and the sound decrease button part of the sound button share an elastic body. Two side keypads can be set on the elastic body, one side keypad is set corresponding to the sound increase button part, and one side keypad is set corresponding to the sound de...

Abstract

The invention discloses a side key waterproof device of a mobile terminal. The side key waterproof device comprises a side key, wherein the side key is arranged in a side key mounting hole of a shell of the mobile terminal; an elastomer, wherein the elastomer comprises a side key area used for mounting the side key and an extension area hermetically connected with the side key area, the extension area is arranged on an inner wall of the shell and surrounds the side key mounting hole; and a sealing body arranged on the inner wall of the shell for sealing the gap between the extension area and the shell. When sealing is realized by the elastomer and the sealing body, the extension area of the elastomer is located on the inner wall of the shell, so no accommodation groove and the like needs to be formed in the shell, and accordingly the structure of the shell can be simplified. The invention further discloses a mobile terminal.

Description

technical field [0001] The present application relates to the technical field of mobile terminals, in particular to a side key waterproof device of a mobile terminal, and also relates to a mobile terminal provided with the side key waterproof device. Background technique [0002] Side keys such as sound keys and / or power keys of some mobile terminals (such as mobile phones, tablet computers, etc.) are usually arranged on the side walls of the mobile terminal to facilitate the use of the side keys or increase the screen as much as possible. [0003] In order to improve the waterproof and dustproof performance of the mobile terminal, a waterproof device will also be provided at the position of the side key. At present, a side key waterproof device integrates the side key and the casing by injection molding. But the mold of this side key waterproof device is complicated, takes a lot of effort. [0004] As an improvement on the above-mentioned side key waterproof device, anoth...
