Mobile terminal

Abstract

The invention discloses a mobile terminal, relates to the technical field of mobile terminal structure design, and aims to solve the problems of worse plugging experience and poor sealing performanceof a traditional side hole waterproof product of the mobile terminal. The mobile terminal comprises a terminal body, a side edge hole is formed in the side wall of the terminal body, the mobile terminal further comprises a side edge waterproof plug, and the side edge waterproof plug comprises a first body made of a hard plastic material. The first body comprises a plugging part and a sealing part,and the plugging part is fixedly connected with the sealing part. The sealing part is wrapped with a silicon rubber case, the sealing part and the silicon rubber case are of an integrally-formed structure, and the sealing part wrapped with the silicon rubber case is in interference fit with the side edge hole of the mobile terminal. The mobile terminal is used for sealing and waterproofing the side hole of the mobile terminal.

Description

technical field [0001] The present invention relates to the technical field of mobile terminal structure design, in particular to a mobile terminal. Background technique [0002] The waterproof plug inserted into the side hole of the traditional mobile terminal (such as earphone hole, USB hole, card tray hole, etc. in the three-proof portable terminal), which is located in the appearance part outside the side hole of the mobile terminal and inserted into the side hole of the mobile terminal The sealing part is made of TPU (Thermoplastic polyurethanes thermoplastic polyurethane elastomer rubber) material, and the sealing waterproof surface of the sealing part of the waterproof plug is interference fit with the side hole of the mobile terminal. [0003] However, the hardness of the TPU material is 70-95 degrees. During the process of plugging and unplugging the waterproof plug, due to the softness of the TPU material, when the finger acts on the appearance part, it will cause ...

AI Technical Summary

Problems solved by technology

[0003] However, the hardness of the TPU material is 70-95 degrees. During the process of plugging and unplugging the waterproof plug, due to the softness of the TPU material, when the finger acts on the appearance part, it will cause deformation of the appearance part, which cannot produce a good point of force, and the hand feel is relatively blunt, poor experience

At the same time, the TPU material has poor resilience. After the mobile terminal passes through harsh environments such as high temperature and high humidity, the size of the waterproof surface of the sealing part of the waterproof plug will change, which will easily cause differences in the plug-in feel and changes in waterproof performance.

[0004] In existing products, the waterproof effect and plug-in feel are mainly improved by optimizing the hardness of the TPU material and the size of the interference fit. However, the hardness of the material can only be optimized within the hardness range of the material itself, and cannot change the characteristics of the material itself. The matching size can only be improved within the allowable range of the actual application, which cannot overcome the defects of the TPU material itself

Therefore, the waterproof effect of the waterproof plug and the feel of plugging and unplugging have not been significantly improved.
