Problems solved by technology

[0003] The disadvantage of the current conventional mobile phone key waterproof structure is that in order to prevent the key from piercing the waterproof soft rubber, the waterproof soft rubber in the existing waterproof structure needs a relatively thick elastic wall, and the waterproof soft rubber is separated from the key, usually located under the key , the structure is not tight, resulting in the traditional waterproof buttons occupying a relatively large space, resulting in a thicker mobile phone and a wider frame
Therefore, it cannot meet the current trend of thinner, lighter and narrower mobile phones

Abstract

The invention discloses a waterproof button structure and a mobile terminal device. The waterproof button structure comprises a button cap, of which side wall is provided with a groove; a flexible glue, of which center is provided with a through hole, wherein elastic wall is arranged at surrounding of the through hole; a bonding layer, which is located at the edge of the upper surface of the flexible glue at the outside of the elastic wall, and used for bonding the waterproof button structure with a device shell body; the button cap crosses through the through hole of the flexible glue, and the elastic wall of the flexible glue is in interference fit with a button cap groove. The waterproof button structure is compact in structure and small in occupied space; moreover, the thickness of the mobile terminal device and the width of the side frame are reduced; besides, the waterproof button structure has waterproof function.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of waterproof button structure design, and in particular, to a waterproof button structure and a mobile terminal device. Background technique [0002] Waterproof mobile phones are more and more popular among consumers because of their unique performance, and there are more and more waterproof mobile phones on the market. [0003] The disadvantage of the current conventional mobile phone key waterproof structure is that in order to prevent the key from piercing the waterproof soft rubber, the waterproof soft rubber in the existing waterproof structure needs a relatively thick elastic wall, and the waterproof soft rubber is separated from the key, usually located under the key , The structure is not compact, resulting in the traditional waterproof buttons occupying a relatively large space, resulting in a thicker mobile phone and a wider frame. Therefore, it is impossible to meet the...
