Embodiment 1

[0043] refer to figure 1 , the key waterproof structure includes a pressing part 2 and a flexible part 3, refer to figure 2 , the pressing part 2 is made of aluminum alloy material, and the pressing part 2 specifically includes a side button 21, a pressing foot 22 and a snap-in piece 5, and the side button 21 is used for the user to perform a pressing action. A boundary groove 211 is formed on the side wall of the button 21, and the boundary groove 211 is roughly located in the middle of the side button 21. The existence of the boundary groove 211 has the function of a boundary line, which is convenient for the user to press the two ends of the side button 21 more accurately. The locking piece 5 is installed on the side wall of the side button 21 facing away from the boundary groove 211 , and the surface area of ​​the locking piece 5 is larger than that of the side button 21 on the side where it is located. The pressing feet 22 are installed vertically on the clamping piece ...

Embodiment 2

[0054] refer to Figure 8 The difference from Embodiment 1 lies in the supporting part. In this embodiment, the supporting part includes a plastic sheet 6 and a positioning ring 62 integrally connected with the plastic sheet 6. Both the plastic sheet 6 and the positioning ring 62 are made of plastic material. , the positioning ring 62 is installed on the edge of the plastic sheet 6, and the plastic sheet 6 abuts against the bottom wall of the slot 33. When the supporting part is in the flexible part 3 , the plastic sheet 6 is in contact with the inner bottom wall of the slot 33 , and the outer wall of the positioning ring 62 is in contact with the inner wall of the sealing ring 32 .

[0055] A second opening 61 is provided on the plastic sheet 6, and the second opening 61 is used for the pressing foot 22 to easily press to the waterproof elastic wall 31. In this embodiment, the second opening 61 is set opposite to the pressing foot 22, and the second opening 61 The opening ar...

Abstract

The invention relates to a key waterproof structure and a three-proofing mobile phone using the same. The key waterproof structure comprises a pressing part which is in plugging fit with the side wall of a housing, and a flexible part which is used for abutting against a trigger button in a mobile phone. The flexible part is matched with the pressing part. The pressing part presses the trigger button by extruding the flexible part so as to enable the trigger button to work. The flexible part and the pressing part form a sealing structure so as to achieve the waterproof purpose. A supporting part is detachably installed in the flexible part, and the supporting part is used for supporting the flexible part and enabling an extrusion part to easily press the trigger button. The pressing comfort is improved, and a waterproof effect can be achieved.

Description

technical field [0001] The present application relates to the technical field of communication equipment, in particular to a key waterproof structure and a three-proof mobile phone using the structure. Background technique [0002] The characteristics of the rugged mobile phone are very simple, that is, the mobile phone with slight dustproof, shockproof and waterproof functions, mainly for young users who love outdoor sports or professional users with special needs. With its professional waterproof, dustproof and excellent anti-drop and anti-rolling performance, the rugged mobile phone can be used in extremely harsh weather conditions and special occasions. [0003] For the waterproof structure of the side buttons of the three-proof mobile phone, two methods are generally adopted. One is that the three-proof casing is made of thermoplastic polyurethane rubber (TPU) as a whole, and the side buttons are integrated with the casing. It can meet the requirements, therefore, it c...
