Clamping plates 7 are provided on the inner sides of the four circumferences of the placement groove 3. The clamping plates 7 can perform reciprocating linear motion in the horizontal direction. A number of uniformly distributed limiting rods 11 are provided on both sides of the upper end surface of the battery pack 2. The limiting rods 11 can expand and contract in the horizontal direction.

[0024] Specifically, first place the battery pack 2 inside the transport box 1. Then, the clamping plate 7 will move towards the battery pack 2 to clamp the battery pack 2. Next, the limiting rod 11 will extend into the transport box 1 and contact the upper end of the battery pack 2 to limit and fix the battery pack 2 in the vertical direction, thus completing the fixation of the battery pack 2. When it is necessary to remove the battery pack 2, first retract the limiting rod 11 into the transport box 1, and then move the clamping plate 7 in the direction opposite to the battery pack 2 to release the battery pack 2, so that the battery pack 2 can be conveniently removed. The purpose of this design is to clamp and fix the battery pack 2 through the clamping plate 7, eliminating the need for a large number of screws to fix the rack, greatly improving the packaging efficiency of the battery pack 2. Then, the limiting rod 11 limits the battery pack 2 in the vertical direction, making its vertical support firm, and the battery pack 2 is not easily loosened or damaged, increasing the reliability of the battery pack 2 during transportation and solving the problem that the existing rack needs to be fixed with a large number of screws during use, resulting in a cumbersome and complex process when locking and fixing the battery pack 2.

[0025] Further, as Figure 2 and Figure 3 shown, the following preferred technical solutions are provided:

[0026] Circular grooves 5 are provided in the middle of the inner walls around the placement groove 3. A hydraulic rod 6 is fixedly installed inside the circular groove 5. The output end of the hydraulic rod 6 is fixedly connected to the middle of the back surface of the clamping plate 7. The purpose of this design is to drive the clamping plate 7 to perform reciprocating linear motion in the vertical direction through the expansion and contraction of the output end of the hydraulic rod 6, thereby clamping and fixing the battery pack 2 placed inside the placement groove 3.

[0027] Further, as Figure 1 、 Figure 2 and Figure 5 shown, the following preferred technical solutions are provided:

[0028] Rectangular grooves 9 corresponding to and adapted to the limiting rods 11 are provided on the inner walls on both sides of the placement groove 3.

Rectangular through holes 12 corresponding to the rectangular grooves 9 are provided on the upper end surface of the transport box 1. The rectangular through holes 12 communicate with the inside of the rectangular grooves 9. One end of a moving rod 13 is fixedly connected to the end of the limiting rod 11 close to the spring 10, and the end of the moving rod 13 away from the limiting rod 11 passes through the rectangular through hole 12. The purpose of this design is to drive the limiting rod 11 to expand and contract inside the rectangular groove 9 through the movement of the moving rod 13. The spring 10 can use its own elastic force to make the limiting rod 11 extend out of the rectangular groove 9 to limit the battery pack 2, thereby realizing simple and rapid locking and fixing of the battery pack 2.

[0029] Further, asFigure 2 and Figure 5 as shown in the figure, the following preferred technical solutions are provided:

[0030] One end of the limiting rod 11 away from the inner wall of the placement groove 3 is provided with a first fixing hole 14, and a second fixing hole 15 corresponding to the first fixing hole 14 is provided on one side of the upper end surface of the transport box 1. The purpose of such design is that by inserting a bolt into the first fixing hole 14 and the second fixing hole 15, the contracted limiting rod 11 can be fixed, so that the battery pack 2 can be conveniently removed.

[0031] Further, as Figure 1 and Figure 4 shown in the figure, the following preferred technical solutions are provided:

[0032] A cover plate 16 is movably installed on the upper end surface of the transport box 1, and clamping blocks 17 are fixedly installed at the four corners of the cover plate 16.

[0033] Further, as Figure 3 shown in the figure, the following preferred technical solutions are provided:

[0034] A rubber pad 8 is fixedly attached to the side surface of the clamping plate 7 close to the battery pack 2. The purpose of such design is that the rubber pad 8 can enhance the friction between the clamping plate 7 and the battery pack 2 and can prevent the clamping plate 7 from scratching the surface of the battery pack 2.

[0035] Further, as Figure 2 shown in the figure, the following preferred technical solutions are provided:

[0036] A buffer pad 4 is fixedly attached to the inner bottom surface of the placement groove 3. The purpose of such design is that the buffer pad 4 can buffer the placed battery pack 2 to prevent it from being damaged due to vibrations generated during transportation.

[0037] In summary: First, place the battery pack 2 inside the transport box 1. Subsequently, the clamping plate 7 will move towards the battery pack 2 driven by the output end of the hydraulic rod 6 to clamp the battery pack 2. After that, the limiting rod 11 will extend into the transport box 1 under the elastic force of the spring 10 and contact the upper end of the battery pack 2 to limit and fix the battery pack 2 in the vertical direction, thus completing the fixation of the battery pack 2. When it is necessary to remove the battery pack 2, first move the moving rod 13 in the direction opposite to the battery pack 2, then the limiting rod 11 can be retracted into the transport box 1. Next, insert the pin into the first fixing hole 14 and the second fixing hole 15 to fix the position of the limiting rod 11. Then, make the output end of the hydraulic rod 6 drive the clamping plate 7 to move in the direction opposite to the battery pack 2 to release the battery pack 2, and then it is convenient to take out the battery pack 2 in the transport box 1. The purpose of this design is to clamp and fix the battery pack 2 through the clamping plate 7, without the need for a large number of screws to fix the rack, which greatly improves the packaging efficiency of the battery pack 2. Then, the vertical direction of the battery pack 2 is limited by the limiting rod 11, making its vertical support reliable, and the battery pack 2 is not easily loosened and damaged, increasing the reliability of the transportation of the battery pack 2, and solving the problem that the existing rack needs to be fixed by a large number of screws during use, resulting in a cumbersome and complex process when locking and fixing the battery pack 2.
