Patent ID: 7632581

Claim:
A battery box, comprising: a housing comprising a receiving space in a side thereof for receiving at least one battery therein, and a mounting wall at an opposite side thereof, the receiving space defining two slots at opposite ends thereof; two first positive electrode members slidably mounted to opposite ends of the housing respectively, each of the first positive electrode members comprising a sliding portion slidably mounted to the mounting wall of the housing, and a positive electrode terminal extending from the sliding portion and located at a corresponding one of the two slots in the receiving space configured for contacting with a positive electrode of the at least one battery; at least two first negative electrode members mounted to opposite ends of the housing respectively, each of the at least two first negative electrode members comprising a mounting portion mounted to the mounting wall of the housing, and a negative electrode terminal located in the receiving space of the housing configured for contacting with a negative electrode of the at least one battery; an elastic returning structure elastically and electrically connected between the sliding portions of the first positive electrode members; and at least one second negative electrode member non-electrically mounted to the elastic returning structure, the at least one second negative electrode member moving together with the elastic electric assembly to touch with a corresponding mounting portion of the at least two first negative electrode members when assembling the at least one battery.
