DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following further elaborates on the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0017] An ultra-thin battery PACK housing structure, comprising a PACK bottom case 1, a box upper cover 2, an explosion-proof valve 10, a module pressing strip 11, a battery module 12, a communication module 13, a circuit breaker 14, a waterproof window cover 15, a key switch 16, positive and negative output sockets 17, an LED light board 18, a communication port 19, and a BMS board 20. The box upper cover 2 and the PACK bottom case 1 are fixed together by countersunk head screws. The explosion-proof valve 10 is arranged on one side of the PACK bottom case 1. The battery module 12 and the communication module 13 are fixed inside the PACK bottom case 1, and the battery module 12 is further tightly fixed inside the PACK bottom case 1 by the module pressing strip 11. The circuit breaker 14, the waterproof window cover 15, the key switch 16, the positive and negative output sockets 17, the LED light board 18, and the communication port 19 are sequentially fixed to one end of the PACK bottom case 1 from top to bottom.
