Key waterproof structure and electronic device applying same

Abstract

The invention relates to a key waterproof structure which comprises a front shell, a key assembly and a circuit board assembly. The circuit board assembly comprises a circuit board and a soft material piece. The circuit board comprises a connection end and is wrapped in the soft material piece, the connection end stretches out from one side of the soft material piece, the circuit board is further provided with at least one key elastic piece. The key assembly comprises keycaps corresponding to the key elastic pieces in number and position. A blind slot is formed in the front shell, and the side wall of the blind slot is provided with a through hole. The circuit board assembly is located between the key assembly and the bottom face of the blind slot. The key assembly abuts against the circuit board assembly and is clamped to the front shell in a matched mode. The connection end stretches into the inner side of the front shell through the through hole and is assembled to the through hole in a sealed mode; meanwhile, the keycaps and the key elastic pieces are correspondingly connected together, and the key function can be achieved through pressing and abutting of the keycaps and the key elastic pieces.

Description

technical field [0001] The invention relates to the field of electronic products, in particular to a key waterproof structure and an electronic device using the key waterproof structure. Background technique [0002] In the waterproof structure design of various outdoor electronic products, the waterproof structure of the main button is one of the important waterproof points. Please refer to Figure 1 to Figure 4 , which is a schematic diagram of the waterproof structure of the main button in the prior art, which includes a front case 100, a main button group 200, a circuit board 300 and a silicone part 400, the front case 100 is provided with a through hole 110, surrounding the through hole The hole 110 is also provided with a circle of grooves 120, and a circle of protrusions 130 is formed between the grooves 120 and the through hole 110; the main key set 200 includes nine keycaps 210; the circuit board 300 is provided with Nine button shrapnels 310; one side of the sili...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a key waterproof structure, which can solve the problem that the circuit board in the prior art must rely on additional waterproof isolation protection when it is applied to waterproof products because it is not designed for waterproof protection. , so that the design, use is limited, and lacks flexibility; in addition, it can solve the problem of difficult and time-consuming assembly of the waterproof structure of the main button described in the prior art, and also solves the need to reserve special points in the prior art. The size of the whole machine is large due to the position of the glue space, or the problem of the large frame of the whole machine and the small size of the buttons, and solve the problem of fixing the waterproof position caused by the matching relationship between the size of the glue dispensing position and the button group in the prior art , the problem of lack of design flexibility; and the problem of poor waterproof reliability caused by poor dispensing operation consistency caused by narrow and long features

[0006] Another technical problem to be solved by the present invention is to provide a waterproof mobile phone, which can solve the problems of difficult and time-consuming assembly of the main buttons in the waterproof mobile phone described in the prior art, and also solve the problems of existing In the technology, due to the need to reserve a special dispensing space, the size of the whole machine is large, or the frame of the whole machine is large and the size of the buttons is small, and solve the problem of the size of the dispensing position and the button group in the prior art. The waterproof position caused by the corresponding relationship is fixed, and the problem of lack of design flexibility

Poor consistency of dispensing operation caused by narrow and long characteristics, resulting in poor waterproof reliability
