Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of cell phone shell, especially relates to a cell phone shell with full air bag anti -fall. BACKGROUND

[0002] In the society, the cell phone is a necessity for people, and with the improvement of living standards, people constantly pursue better cell phones, and require higher configuration of cell phones, one of the demands is that the screen resolution of cell phones is higher and higher, and similarly, the price of cell phone screen is more and more expensive, such as the curved screen of a certain brand, the replacement price reaches 2000 yuan after breaking, which is one third of the price of the cell phone. Therefore, a new cell phone shell is needed to ensure that the screen will not be damaged when the cell phone falls at any angle within the normal height range. After thinking and consulting materials, we think that the technology of automobile safety air bag can be applied to the cell phone shell, and a large amount of gas is generated by the reaction of the reactants to make the elastic film on the cell phone shell expand to wrap the cell phone to buffer the impact of falling and ensure that the cell phone will not be damaged.

[0003] However, in the prior art, for example, the patent with the authorization announcement number CN207099122U and the name of a cell phone shell with safety air bag, when the cell phone touches the ground, one of the four corners of the cell phone shell is triggered by the piezoelectric ceramic trigger. Since the cell phone shell is higher than the screen itself, if the screen touches the ground, the piezoelectric ceramic trigger is the first to contact the ground. When the side touches the ground, the piezoelectric ceramic trigger of one corner will also be affected by the force and trigger the reaction. Due to the effect of pressure, positive and negative charges are gathered, which causes ignition, and the ignition energy makes the combustible material in the wrapping material ignite and react. The heat released by the reaction of the combustible material makes the reactants in the reaction layer decompose and release gas to pop out the air bag. The air bag wraps the cell phone to protect it. However, the above-mentioned patent has the risk of spontaneous combustion, and mainly relies on the impact force caused by the release of instantaneous gas to buffer, which obviously has certain limitations, and the manufacturing cost is high. The second anti-falling effect is obviously weakened.

[0004] Therefore, how to provide an anti-falling cell phone shell with simple structure, low manufacturing cost and full wrapping effect is one of the technical problems that technicians in the field need to solve. Utility model content
