Example Embodiment

[0022] The specific embodiments and embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The specific embodiments described are only used to explain the present invention and are not used to limit the specific embodiments of the present invention.

[0023] Such as figure 1 As shown, figure 1 It is an exploded view of the shell and button silica gel used in the side button waterproof structure of the mobile terminal of the present invention. Taking a certain waterproof mobile phone as an example, the side button waterproof structure is arranged on the mobile phone shell 100, including the button communication associated with the side buttons. Hole 101 and button silica gel 200.

[0024] Combine figure 2 As shown, figure 2 It is a partial enlarged cross-sectional view of the housing used in the side key waterproof structure of the mobile terminal of the present invention at the key through hole. The key through hole 101 ...

Abstract

The invention discloses a waterproof structure for side keys of a mobile terminal and a waterproof mobile phone. The waterproof structure is arranged on the side of a shell and comprises key through holes and key silicone. Key columns adaptively penetrating through the key through holes are arranged in the middle of the bottom of the key silicone and are used for conducting pressing action of the side keys to corresponding metal domes. Closed annular grooves are arranged on the outer surface of the shell on the periphery of the key through holes, and a ring of annular bosses are arranged on the periphery of the bottom of the key silicone and are in interference fit with the annular grooves. The annular bosses in interference fit with the annular grooves located on the periphery of the key through holes on the outer surface of the shell are used to the key silicone of the side keys, so that high cost caused by the use of secondary injection molding process is avoided, production cost of the side keys is reduced, damage, by sharp flanging hole-edged angles in use, of the key silicone due to the use of metal sheets is avoided, and long-term service life of the side keys is guaranteed.

Description

technical field [0001] The invention relates to the field of waterproof structures at the side buttons of mobile terminals such as mobile phones and tablet computers and mobile phones with waterproof functions, in particular to a low-cost, long-life waterproof mobile phone and side key waterproof structures of mobile terminals. Background technique [0002] With the increasing popularity and development of mobile phones, customers have various requirements for mobile phones. For some outdoor sports enthusiasts, waterproof mobile phones are more and more popular among them. Now, under the development trend of increasingly thinner and lighter mobile phones, the waterproof structure at the side buttons has become the weak link of waterproof mobile phones. [0003] Most of the side key waterproof structures in the prior art adopt the process of secondary injection molding when making the mobile phone case, and inject a layer of soft rubber at the position of the corresponding si...
