[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] like Figures 1 to 6As shown, the battery housing of the utility model includes a base 1 and an outer cover 2. The lower end of the outer cover 2 is provided with a first connector 3 for connecting one end of all lithium batteries 4. A placement area 5 for placing the lithium batteries 4 is formed by hollowing out the middle of the base 1. A second connector 6 is provided in the placement area 5. The second connector 6 is used to connect the other ends of all lithium batteries 4. The two ends of multiple lithium batteries 4 are extended to the outside through metal connectors through the first connector 3 and the second connector 6, so as to be connected to external wires.

[0025] An extension lip 7 is provided at both ends of the base 1, and an elastic arm 8 and a fixed arm 9 are provided at both ends of the outer cover 2. The fixed arm 9 is placed at the lower end over the extension lip 7, and a deformation area 10 is formed between the elastic arm 8 and the fixed arm 9. When the lithium battery 4 is placed in the placement area 5, the outer cover 2 only needs to be directly pressed onto the base 1, so that the fixed arm 9 on the outer cover 2 is pushed by the extension lip 7 and compressed into the deformation area 10, and then the fixed arm 9 is placed at the lower end of the extension lip 7, and the fixed arm 9 is fixed by the extension lip 7, so that the outer cover 2 can be stably installed on the base 1.
