Waterproof key structure and mobile phone using same

Abstract

The invention relates to a waterproof key structure which comprises a shell, a key switch, a flexible material part and a key. The key switch and the key are assembled on the shell in a position corresponding mode. The key is movably assembled on the shell. The flexible material part is installed on the key in a sleeved mode and pasted on the shell. When pressed, the key can abut against the key switch. A rigid supporting layer is arranged on one face of the flexible material part and pasted on the shell. The key extrudes the flexible material part in the pressing direction until the flexible material part deforms to be assembled together with the shell. In the structure, a rigid support is additionally arranged on foam and used for improving the assembling and locating performance; meanwhile, in the key assembling process, the flexible material part is pressed in advance so as to be in a compressed deformation state after being assembled, and therefore the good waterproof performance of the portion between the flexible material part and the shell is achieved; in addition, when the key is pressed, the direction of pressure is perpendicular to the pasting face of the flexible material part, and therefore the flexible material part can be prevented from slipping or falling from the shell, and the problem that the key is out of work can be avoided.

Description

technical field [0001] The invention relates to a key waterproof structure and a mobile phone using the waterproof structure. Background technique [0002] Outdoor electronic products need to adapt to various complex outdoor environments, so new requirements are put forward for their manufacturing and assembly processes, such as waterproof, and the waterproof of buttons is increased due to their limited structural space and the need for continuous pressing movements to conduct. For waterproof difficulty, please refer to figure 1 The key waterproof structure of outdoor mobile phone shown, it comprises a housing 100, a key 200, a silicone part 300 and a key switch 400, and described key 200 comprises a key cap 201 and a convex column 202, and described key cap 201 A stepped flange 203 is provided on the outer edge, and a button slot 101 is provided on the housing 100. In the thickness direction of the flange 203, the width of the slot 101 is greater than the thickness of the ...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a key waterproof structure, which can solve the problem that the silicone sleeve in the prior art is easy to fall off from the casing after the key is pressed and used many times, causing the The problem of waterproof failure and the failure of the button function also solves the problem of low assembly efficiency caused by the inconvenience of taking and placing the soft material parts

[0004] Another technical problem to be solved by the present invention is to provide a waterproof mobile phone that adopts the waterproof structure of the key, and the mobile phone can solve the problem of waterproof failure of the key of the mobile phone that exists in the prior art because the silicone sleeve is easy to fall off. And the low assembly efficiency of the silicone sleeve because it is a soft part
