[0002] With the continuous development of social economy and the continuous advancement of modern science and technology, the number of electric products has increased rapidly, and various electric vehicles, electric cars and other devices have emerged. The most important component of electric equipment is the battery. The amount of battery power and the quality of its performance will directly affect the normal use and cruising range of the equipment.

[0003] However, the batteries of most electric products on the market need to be completely disassembled in order to replenish or replace the power when the power is insufficient. At the same time, most traditional batteries have no protection function. If such batteries oscillate or collide during use, the battery body will continue to collide, which is very likely to cause damage to the battery body, and then the battery may be damaged, thus affecting its use.

[0004] Therefore, those skilled in the art provide a detachable rechargeable battery housing to solve the problems raised in the above background technology. Utility Model Content
