[0048] Specifically, if Figure 1 and Figure 2 As shown, the battery rack positioning device includes a base frame 1, a first positioning mechanism 2 and a second positioning mechanism 3, wherein the first positioning mechanism 2 and the second positioning mechanism 3 are both arranged on the base frame 1, the first positioning mechanism 2 includes an X-direction push plate assembly 21 and an X-direction limit plate 22 relatively arranged along the X direction, the X-direction push plate assembly 21 can move toward the X-direction limit plate 22, so that the X-direction push plate assembly 21 and the X-direction limit plate 22 are clamped together on both sides of the length direction of the battery rack, and the second positioning mechanism 3 includes a Y-direction push plate assembly 31 and a Y-direction limit plate 32 relatively arranged along the Y direction, the Y-direction push plate assembly 31 can move toward the Y-direction limit plate 32, so that the Y-direction push plate assembly 31 and the Y-direction limit plate 32 are clamped together on both sides of the width direction of the battery rack. When the forklift places the battery rack on the chassis 1, the X-direction push plate assembly 21 pushes the battery rack toward the X-direction limit plate 22 to adjust the battery rack in the X direction until the X-direction push plate assembly 21 and the X-direction limit plate 22 are clamped together on both sides of the length direction of the battery rack, thereby achieving precise positioning of the battery rack in the length direction. The Y-direction push plate assembly 31 pushes the battery rack toward the Y-direction limit plate 32 to adjust the battery rack in the Y direction until the Y-direction push plate assembly 31 and the Y-direction limit plate 32 are clamped together on both sides of the width direction of the battery rack, thereby achieving precise positioning of the battery rack in the width direction, thereby ensuring that the battery rack positioning device can achieve precise positioning of the battery rack without manual adjustment, thereby improving the handling efficiency of the battery pack.

[0049] Preferably, if Figure 1 As shown, a plurality of X-axis limit plates 22 are provided, and the plurality of X-axis limit plates 22 are arranged at intervals along the Y direction on the base frame 1. When the X-axis push plate assembly 21 completes the movement of the battery rack, the plurality of X-axis limit plates 22 abut against and fix the battery rack together to prevent the battery rack from shifting, thereby improving the stability of the battery rack fixation.

[0057] Specifically, the Y-direction driving member 311 can be an electric push rod, and the Y-direction push plate 312 can be moved relative to the base frame 1 through the telescopic movement of the electric push rod, thereby pushing the battery rack to move. In addition, the electric push rod also has the advantages of reliable performance, sensitive action, smooth operation and good environmental adaptability. The Y-direction push plate 312 can be a rectangular plate composed of four rods, which not only increases the pushing area of ​​the battery rack, but also makes the Y-direction push plate 312 move more smoothly.

The two groups of support platform assemblies 41 jointly support the battery rack, and the support platform assemblies 41 can move relative to the base frame 1. When the X-axis pushing plate 212 and the Y-axis pushing plate 312 push the battery rack, the support platform assembly 41 carries the battery rack and moves relative to the base frame 1, thereby making the battery rack move more smoothly and stably.

[0062] It should be noted that the two groups of support platform assemblies 41 are located between the X-axis pushing plate 212 and the X-axis limit plate 22. The battery rack is a four-legged support structure, in which one group of support platform assemblies 41 supports the two legs of the battery rack arranged along the Y direction, and the other group of support platform assemblies 41 supports the other two legs of the battery rack along the Y direction.
