The invention belongs to the field of mobile phone accessories, and in particular relates to a back clip battery sheath, which aims to solve the problem that the existing back clip battery sheath is assembled by several structural parts so that it occupies a large space and the battery capacity is low and requires different molds for Injection molding several structural parts causes technical problems of structural complexity. The protective cover is made of soft materials. The battery, charge and discharge control circuit board, and support frame are all fixed in the inner cavity of the protective cover. The mobile phone is placed in the inner cavity, surrounded by the protective wall and locked by the hook. This structure has Larger space accommodates larger capacity batteries. The terminal circuit board is installed on the supporting frame, and the mobile phone is connected with the terminal circuit board to realize charging of the mobile phone. Two sets of molds can be used to produce two structural parts of the protective cover and the support frame, and the production cost is low. The protective cover made of soft material feels good, is not easy to be scratched, and can also resist falls. The back clip battery sheath has the characteristics of simple structure, easy assembly, convenient assembly and disassembly of mobile phones, small space occupation, and large battery capacity.
Description
technical field [0001] The invention belongs to the field of mobile phone accessories, in particular to a back clip battery sheath. Background technique [0002] Back clip battery sheath is also called "external battery", "backup battery", "digital charging companion", it is not only a mobile power supply, but also a protective case. In the prior art, the back clip battery jacket is usually made of ABS (acrylonitrile-butadiene-styrene copolymer) or PC (polycarbonate) by injection molding several structural parts, and then these structural parts and the battery , circuit boards and other parts assembled. [0003] One of the back clip battery sheaths is mainly assembled from four structural parts including an upper cover, a lower cover, a fixing plate and a frame, a battery, a charge and discharge control circuit board, and a terminal circuit board. The upper cover and the lower cover are fixed, and The charging and discharging control circuit board is packaged between the u...
