[0040] Each battery positioning and protection unit 2 includes a battery protection upper shell 21 and a battery support and positioning lower shell 22;

[0041] In the battery support and positioning lower shell 22, there is a laterally distributed battery embedding lower groove 221 with an open top;

[0042] In the battery protection upper shell 21, there is a laterally distributed battery embedding upper groove with an open bottom;

[0043] The battery embedding upper groove and the battery embedding lower groove 221 are arranged corresponding to each other up and down;

[0044] The battery embedding upper groove and the battery embedding lower groove 221 are buckled together to form a receiving cavity for placing one single cell;

[0045] At positions corresponding to the positive electrode post and the negative electrode post on the single cell in the receiving cavity, there are respectively a positive electrode post clearance groove 222 and a negative electrode post clearance groove 223;

[0046] At a position corresponding to the explosion-proof valve (i.e., pressure relief valve) on the single cell in the receiving cavity, there is an explosion-proof valve clearance groove;
