Electronic device with pressure relief structure

Abstract

The invention relates to an electronic device with a pressure relief structure. The device comprises a first shell, a sealing part and a second shell, the sealing part is arranged between the first shell and the second shell, the first shell and the second shell are arranged on the sealing part in a press fitting mode until the first shell and the second shell are deformed to be assembled together, a sealing space is formed between the first shell and the second shell, the pressure relief structure comprises at least one ventilation waterproof film and at least one pressure relief hole, the pressure relief hole is formed in at least one of the first shell or the second shell, and the ventilation waterproof film is arranged on the pressure relief hole and is sealed with the edge of the pressure relief hole. Therefore, when the device is used for the different environments with the large temperature or pressure changes, the pressure relief structure can keep connectedness and consistency of the shell sealing space and the external temperature and pressure all the time, so that the electronic device can be normally used in the different environments with the rapid changes of temperature and pressure.

Description

technical field [0001] The invention relates to a pressure relief structure, in particular to an electronic device using the pressure relief structure. Background technique [0002] At present, outdoor sports are getting more and more attention and love from people, and the outdoor environment is changeable, so people put forward new requirements for the tolerance of outdoor electronic products to environmental changes. Existing outdoor electronic products are generally designed as a cavity seal due to the need for waterproof and dustproof. Taking an outdoor mobile phone as an example, it includes a front case, a seal and a rear case, and the seal is located on the front case. Between the front shell and the rear shell, the sealing member is pressed together to deform to realize the sealing between the front shell and the rear shell, so as to realize the waterproof and dustproof effect. Due to the sealing of the shell between the front shell and the rear shell, when people ...

AI Technical Summary

Problems solved by technology

Due to the sealing of the shell between the front shell and the rear shell, when people carry mobile phones for outdoor sports, they often experience sharp changes in temperature and air pressure. At this time, for the sealed cavity between the shells, the The air in the air will expand with heat and contract with cold, which will cause the inconsistency of temperature and air pressure inside and outside the cavity, which will not only affect the function of some devices in the cavity, but also may cause sealing failure and poor waterproofing
