Waterproof side key structure and waterproof mobile phone with structure

Abstract

The invention relates to a waterproof side key structure which comprises a key body formed by an elastic material, a key support made of a hard material, an elastic member and a shell. The key body, the key support and the elastic member are assembled on the shell, the key body is pressed, pressing force can be transmitted to the elastic member through the key support, and thus the switch-on of aside key is triggered. At the same time, three levels of waterproof protection are set in the assembly structures of the key body and the shell, a technical scheme of converting a large key stroke into a small keystroke is proposed, and a novel technical idea of the realization of multiple levels of waterproof protection of side keys in a limited structure space at the same time to effectively improving waterproof reliability is proposed.

Description

technical field [0001] The invention relates to the waterproofing of side buttons in the field of waterproof electronic products, in particular to a side button structure with multiple waterproof functions, and also to a waterproof mobile phone using the side button structure. Background technique [0002] With people's enthusiasm for outdoor sports, there are more and more electronic products with waterproof function. As for the waterproofing of the side buttons, usually there is not enough space for a reliable waterproof design due to the limitation of the structural size, so the waterproofing of the side buttons often becomes a major difficulty in product development. [0003] Taking the Chinese invention patent waterproof button and the combination of waterproof button and electronic device casing [authorized announcement number: CN201247703Y] as an example, the invention patent discloses a waterproof structure for side buttons, which includes a button body made of elast...

AI Technical Summary

Problems solved by technology

[0004] In the above prior art, when pressing the key body to turn on the circuit unit, it is necessary to transmit the pressing force through the pressing part to achieve conduction. Due to the structural limitation of the housing, the pressing part has a relatively large The length of the key, and considering that the key body is made of elastic materials such as rubber and silica gel, which is relatively soft and easily deformed under force, it is necessary to provide a larger pressing stroke from pressing to triggering the circuit unit to achieve conduction. The pressing part can also trigger the circuit unit after being deformed enough, that is to say, the pressing stroke required by the prior art includes the stroke caused by the elastic deformation of the pressing part and the distance from the pressing part to the abutting position. There are two parts of the stroke required by the circuit unit; it can be seen that the prior art has the problem that the button has a large stroke and it is difficult to press the circuit unit in place; in addition, the setting of the hard support layer increases the waterproof It is difficult to assemble the ring, and at the same time it is connected with the waterproof body by hot pressing, which also increases the processing cost and increases the processing procedure; in the prior art, the waterproof ring is squeezed and deformed to realize the button position. Waterproof, although it is supported by the hard support layer, there is a risk of waterproof failure due to the processing error of the waterproof ring itself and its synchronous movement with the pressing and recovery of the button body
