Description

Button waterproof construction and applied three proofings cell-phone of this structure

Technical Field

The application relates to the technical field of communication equipment, in particular to a button waterproof structure and a three-proofing mobile phone applying the same.

Background

The three-proofing mobile phone has the characteristics of simplicity, namely the mobile phone with slight dustproof, shockproof and waterproof functions, and mainly aims at young users who love outdoor sports or professional users with special needs. The three-proofing mobile phone can be applied to abnormal and severe weather conditions and special occasions due to professional waterproof and dustproof properties and excellent anti-falling and anti-rolling properties.

To the waterproof construction of three proofings cell-phone side button, generally can adopt two kinds of modes, one kind is that the whole thermoplastic polyurethane rubber (TPU) material that adopts of three proofings casing makes, wherein, the side button sets up with the casing is integrative, because TPU is waterproof can reach the requirement, consequently, also can indirectly make the side button play waterproof effect, but under the actual conditions, because of TPU compliance is relatively poor, so press the feel of downside button also relatively poor. Another kind adopts the mode that side button and casing separately set up, wherein, the mode that the side button relied on to beat to glue is in order to realize waterproof function, actually, beats to glue and increases the process and beat easily and glue the inequality, in addition, because glue has mobility, so can lead to the glued membrane unevenness after the shaping, when the glued membrane unevenness, just can lead to the side button to be pressed on, can not press the accurate position. In addition, no matter which way is pressed, the side key is required to press the trigger button in the shell, and when the trigger button is triggered, the control main board in the shell can output a corresponding control signal, so that the mobile phone can execute a corresponding function.

In view of the above-mentioned related art, the inventor believes that there is a defect that the waterproof structure cannot achieve both convenience in installation and improved hand feeling.
