[0050] As a preferred option, the battery boxes 21 can be connected in series via adapter cables 10, with both ends of the adapter cables 10 inserted into the corresponding adapter interfaces 24 for series connection or use.

[0051] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0052] Example: According to the appendix of the instruction manual Figure 1-12 It can be seen that, firstly, the auxiliary frame 12, base 13 and crossbeam 14 in the frame structure 1 are welded and assembled with the beam frame 11 respectively; then, with the help of the seat rod 6, they can be welded into the rear frame 15 as the rear end of the frame.

[0053] With the help of the stop bar and the towing bar 17, the battery box 21 in the loading structure 2 can be inserted and limited, and then fixed to the side wall of the battery box 21 by means of the fastening bolt 9 passing through the second adjustment groove 8; or the battery box 21 can be embedded into the base 13, and fixed by means of the fastening bolt 9 passing through the first adjustment groove 7 and connecting to the side wall of the battery box 21, so as to realize two installation methods and positions, and can also realize the placement of two sets of batteries;

[0054] When installing a set of loading structures 2, the insertion position of the second partition 23 relative to the first partition 22 can be adjusted according to the number of batteries 25 installed or the two battery models to adjust the placement space so that the batteries 25 are embedded and placed in the limiting position; then the corresponding connecting components 27 are placed on the cover plate 271 according to the arrangement of the batteries.

[0055] After the cover plate 271 is fastened onto the battery box 21, the tightening bolt can be rotated to lower the first insulating plate 272 under pressure. After being lowered by the limiting post 274, the first guide plate 273 is connected in series with the positive and negative terminals of the two attached batteries 25 by the compression spring 276 through the baffle 275. At the same time, the second guide plate 278 is connected in series with the positive and negative terminals of the connected batteries 25, so that the connected batteries 25 are connected in series with the cooling fan 26 and one of the adapter interfaces 24. At this time, the batteries 25 are connected in series to form a U-shaped connection, and then the adapter cable 10 can be used to connect the equipment to form a closed circuit for use.

[0056] In use, the cooling fan 26 drives external air to enter through the air inlet, and through the ventilation slot, multiple batteries 25 can be cooled and discharged from the cooling fan 26.

[0057] When installing two sets of batteries, i.e., installing the two loading structures 2 on the base 13 and the tow bar 17 respectively, it is necessary to modify the connecting component 27 on the cover plate 271 of one of the battery boxes 21. The first guide plate 273 corresponding to the two batteries 25 connected in series in the middle of the corresponding battery box 21 is removed and the second guide plate 278 is replaced. This makes both ends of the batteries 25 connected in series in the battery box 21 the second conductive plate. Then, the other adapter 24, except for the one connected in series with the cooling fan 26, is connected to the replaced second conductive plate through a wire. Then, the two battery boxes 21 can be connected to the adapter 24 through an adapter cable 10 to realize the series use of the batteries 25 in the two battery boxes 21.
