Detailed ways

In order to further disclose the specific technical content of the present utility model, first please refer to the accompanying drawings.

As shown in FIGS. 1 to 6 , basically, the battery box of the present invention includes a box body 1 , a pole piece set 2 , and two wires 3 .

Wherein, the box body 1 is a semi-closed elongated shell, and side walls 12 are vertically arranged on both sides of a bottom wall 11, and the end edges of each side wall 12 are respectively connected to a front wall 13 and a rear wall in a transverse direction. 14, and form a long accommodating space according to it, in order to accommodate and locate the battery, but these are all known skills, and will not be repeated here. Furthermore, in order to separate two adjacent batteries, at least one partition rib 15 is arranged laterally between the two side walls 12 . In addition, at least one line hole 16 must be opened in one of the side walls 12 so as to allow the wires 3 connected to the pole piece set 2 to pass through. In addition, at least two slots 17 are provided in the box body 1 corresponding to the positions of the pole pieces 2 for inserting and positioning the pieces, such as the negative pole piece 21 , the positive pole piece 22 and the relay piece 23 .
