Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, a mobile phone rear cover includes a rear cover layer 1, an air bag layer 2 is movably mounted on a side surface of the rear cover layer 1, and a fixing layer 3 is fixedly mounted on a side surface of the air bag layer 2.

wherein, back lid picture layer 1 includes colour back shroud 11, and the side fixed mounting of colour back shroud 11 has locating pin 12, and locating pin 12 has nine, comes the activity through locating pin 12 and fixes colour back shroud 11, can change colour back shroud 11 when the colour and the pattern that the consumer disliked colour back shroud 11, has solved the single problem of cell-phone back shroud colour pattern, has promoted the diversification of the outward appearance of cell-phone.

Wherein, gasbag layer 2 includes gasbag board 21, and spout 22 has been seted up to the side of gasbag board 21, and the inside movable mounting of gasbag board 21 has compression gasbag 23, and spout 22 has three, offers with the cooperation of locating pin 12, and spout 22 is interference fit with locating pin 12, is interference fit through spout 22 and locating pin 12, has solved the problem that back lid picture layer 1 installed on gasbag layer 2 easy automatic dropping, has promoted smart mobile phone's wholeness.

wherein, fixed layer 3 includes fixed plate 31, the middle part fixed mounting of fixed plate 31 side has air bag controller 32, the middle part of fixed plate 31 side and the top fixed mounting who is located air bag controller 32 have acceleration sensor 33, air bag controller 32 and compression gasbag 23 fixed mounting, cooperation installation through air bag controller 32 and acceleration sensor 33, control inflating of compression gasbag 23, the problem that the cell-phone drops and can damage the cell-phone has been solved, the life of cell-phone has been promoted.
