Falling prevention mobile phone shell

Abstract

The invention relates to a falling prevention mobile phone shell. The falling prevention mobile phone shell comprises a hard hollow backboard and a soft elastic hollow frame, wherein hollow areas of the backboard and the frame are communicated and form a sealed space. The falling prevention mobile phone shell is characterized in that the sealed space is filled with a liquid; the hollow area of the backboard is further provided with a hermetically sealed elastic air bag which can move freely; the external part of the elastic air bag is wrapped with a hermetically sealed flow-limiting shell made of a transparent material, and the flow-limiting shell is provided with flow limiting holes which are arranged at equal intervals in the circumferential direction; and the outer wall of the flow-limiting shell is further provided with memory metal pieces with a two-way memory effect which are installed at equal intervals in the circumferential direction, and each memory metal piece is vertical with the outer wall of the flow-limiting shell. The mobile phone shell provided by the invention is light in texture, can effectively weaken an impact force when a mobile phone falls, and protects the safety of a screen. The falling prevention mobile phone shell has good heat conduction and heat dissipation effects, has a movable logo at the same time, and is more exquisite in appearance.

[0002] In recent years, the mobile phone industry has been booming, and various types of mobile phones have emerged in an endless stream. The competition in the mobile phone industry is becoming more and more fierce. At present, mobile phones are developing in the direction of large, light and thin. With this change in the appearance of mobile phones, the screen of the mobile phone becomes The size of the mobile phone is getting bigger and bigger, the thickness is getting thinner and thinner, but the firmness of the mobile phone is getting lower and lower. Due to the large size of the mobile phone, the probability of dropping it during use increases significantly, so the probability of damage to the mobile phone increases; If the corner touches the ground, it is easy to cause the entire screen to break, causing huge economic losses to the user. If the internal information is lost, it will cause unnecessary troubles; at present, the more solid mobile phones use metal frames, which can guarantee the appearance. The structure is strong, but the impact resistance is insufficient. When the corners are impacted, it will still cause large-scale fragmentation of the screen; in addition, the metal frame will affect the transmission of mobile phone signals
