After withdrawing the fork arms, the height of the supporting part is adjusted again through the adjusting part, so that the power battery 3 is placed on the support frame 3.

[0034] Continue to refer to Figure 1 As shown in the figure, the frame body 1 of the power battery installation frame is composed of a plurality of cross beams, a plurality of longitudinal beams and a plurality of vertical beams by welding. The bottom frame of the frame body 1 and the bottommost support frame 4 form an installation space. The top frame of the frame body 1 and the topmost support frame 4 form an installation space. Each of the two adjacent support frames 4 up and down forms an installation space.

[0035] The above-mentioned lifting components are further described below.

[0036] As Figure 3 、 Figure 4 shown in the figure, the adjusting part includes a lead screw 22 and a ball nut 23. The lead screw 22 is rotationally supported in each installation space 11. The ball nut 23 is installed on the lead screw 22, and the two are in threaded cooperation to form a ball screw structure. The supporting part is a support plate 24, which is fixed on the ball nut 23. The rotational movement between the lead screw 22 and the ball nut 23 can be converted into the up and down linear movement of the support plate 24.

[0037] A further solution is as Figure 1 、 Figure 2 、 Figure 3 shown in the figure. A bearing seat 21 is fixed at each of the upper and lower ends of the lead screw 22, and the bearing seat 21 is fixed on the rigid components located in each installation space 11.

[0040] As Figure 5 shown, the support frame 4 includes a pair of parallel long cross beams 44, a pair of parallel longitudinal beams 45 and a pair of parallel short cross beams 46; a pair of parallel long cross beams 44 are welded to the frame body 1 of the power battery installation frame; a pair of parallel longitudinal beams 45 are fixed in the two long cross beams 44, and a clearance space 42 for accommodating the support plate 24 is formed between each longitudinal beam 45 and the end of the adjacent long cross beam 44. A pair of parallel short cross beams 46 are fixed in the two longitudinal beams 45 in a manner parallel to the long cross beams 44. A plurality of mounting threaded holes 41 arranged at intervals and in a linear arrangement are provided on the two short cross beams 46 and the two longitudinal beams 45, and the power battery 3 is fixed on the support frame 4 by cooperating with the mounting holes 32 on the power battery 3 through bolts.

[0041] A further solution is that, as Figure 5 shown, at least one reinforcing beam 43 is further fixed between the two long cross beams 44, and the reinforcing beam 43 is also located between the two longitudinal beams 45. The reinforcing beam 43 can reinforce the frame and prevent cracking problems.

[0043] A preferred solution: as Figure 1 、 Figure 2 shown, four lifting components 2 are installed in each installation space 11, and the four lifting components 2 are symmetrically distributed on both sides of the power battery 3 to jointly support and adjust the height of the power battery 3.

[0044] The specific steps of the power battery installation method of the present utility model are as follows:

[0045] Step 1: As Figure 1 shown, before the installation program starts, the height of the support plate 24 is adjusted by the ball nut 23 on the lead screw 22 so that the heights of the respective support plates 24 are the same and higher than the position of the mounting threaded holes 41.

[0046] Step 2: Use a forklift to lift the power battery 3, send it into the interior of the frame body 1, and after aligning the positioning holes 31 on the power battery 3 with the positioning threaded holes 25 on the support plate 24 by adjusting the position of the forklift, adjust the forklift to lower the fork arms so that the support plates 24 at the four corners support the power battery 3, and then withdraw the forklift.

[0047] Step 3: Slowly lower the power battery 3 by rotating the threaded lead screw 22 until the mounting holes 32 on the power battery 3 are fitted with the mounting threaded holes 41 on the support frame 4 and the bottom frame of the frame body 1, and then use bolts to fasten and fix the power battery 3 on the support frame 4 and the bottom frame of the frame body 1.

[0048] In summary, the present utility model provides a power battery installation structure. In the installation space 11 formed by the power battery installation frame, there are four threaded lead screws 22 fastened to the power battery installation frame through bearing seats 21. The bearing seats 21 are connected to the power battery installation frame by welding, enabling the threaded lead screws 22 to rotate along the axis of the bearing seats 21. A ball nut 23 is integrated on the threaded lead screw 22, which together with the threaded lead screw 22 forms a ball screw structure, enabling the ball nut 23 to move up and down along the threaded lead screw 22 while the threaded lead screw 22 rotates. Above the ball nut 23, a support plate 24 is fixed by welding. There are positioning threaded holes 25 on the support plate 24, and the positioning threaded holes 25 match the positioning holes 31 on the power battery 3, which are used to fasten the support plate 24 and the power battery 3 with bolts during the assembly process, providing temporary support for the power battery 3 through the support plate 24.

[0049] After pushing the power battery 3 to the designated position by using a forklift device, match the positioning holes 31 on the power battery 3 with the positioning threaded holes 25 on the support plate 24 and fix them with bolts, and then rotate the threaded lead screw 22 to make the support plate 24 carry the power battery 3 to move downward. When the power battery 3 moves to the designated installation position, match the mounting holes 32 on the power battery with the mounting threaded holes 41 on the power battery installation frame and use bolts to fasten to complete the assembly of the power battery 3.
