Description

Back splint battery pack Technical Field The utility model relates to the technical field of battery packs, in particular to a back splint battery pack. Background The back clamp battery pack (also called a mobile phone back clamp battery or a mobile power supply back clamp) is an external battery device, is specially designed for a smart phone, and is usually used as an external battery expander of the mobile phone. It is usually designed as a peripheral closely combined with the back of the mobile phone, provides additional power support for the mobile phone by means of a back clip, helps to prolong the service life of the mobile phone, and is particularly useful in the case of going out or being unable to charge. The prior back splint battery pack mainly comprises an upper cover, a lower cover, a bottom cover, a battery pack arranged on the upper side of the bottom cover, a charging wire arranged on the outer side of the bottom cover and a charging head, when the back splint battery pack with the structure is assembled between the lower cover and the bottom cover, a reserved hooked edge on the lower cover is mainly clamped in a reserved groove on the bottom cover in an interference fit mode, so that the reliable assembly of the lower cover and the bottom cover is realized, although the reliable assembly between the lower cover and the bottom cover of the back splint battery pack can be realized in an interference fit mode, when the bottom cover and the lower cover are subjected to larger tensile force, the hooked edge on the lower cover is easily separated from a hooked groove on the bottom cover, so that the lithium battery part falls off, the use stability of the back splint battery pack is poor, and the timely disassembly and maintenance of the bottom cover and the lower cover are inconvenient when the lithium battery part on the back splint battery pack is damaged. Disclosure of Invention First, the technical problem to be solved The utility model aims to solve the technical problem of the prior art, and provides the back splint battery pack which can realize stable connection of the bottom cover and the lower cover, avoid falling and separation of the bottom cover and the lower cover when the bottom cover and the lower cover are subjected to larger tensile force, and realize rapid disassembly of the lower cover and the bottom cover when a lithium battery part on the back splint battery pack is damaged.
