[0039] A method for using a shock-resistant battery box includes the following steps.

[0040] S1: By installing the battery pack body 7 in the frame 6, the bottom contact surfaces of the multiple support wheels 9 on the bottom side of the frame 6 are against the top side of the shock-absorbing support plate 4, and the rubber transmission belt 14 is sleeved and installed on the first guide roller 12 and the second guide roller 13 on both sides of the frame 6, and the inner side wall of the rubber transmission belt 14 is attached to the multiple limiting rollers 16; at the same time, the multiple gear columns 24 are respectively engaged with the corresponding first rack 17 and second rack 18, and the first cooling fan blades 25 and the second cooling fan blades 26 are respectively fixedly installed on the rotating rods 23 on the multiple gear columns 24.

[0041] S2: During the driving of the new energy vehicle, when the battery pack body 7 is subjected to a vibration force in the horizontal direction or the vertical direction, the rubber transmission belt 14 installed on the first guide roller 12 and the second guide roller 13 at both ends of the frame 6 is used to absorb the force in the horizontal direction. At the same time, the multiple shock-absorbing springs 5 ​​on the bottom side of the shock-absorbing support plate 4 are used to absorb the force in the vertical direction of the battery pack body 7. With the cooperation of the two, the shock-absorbing and absorption of the forces in the horizontal and vertical directions of the battery pack body 7 are achieved.

[0042] S3: When the frame 6 moves to the left or right due to vibration, the multiple sets of gear columns 24 are respectively meshed with the corresponding first rack 17 and second rack 18, thereby synchronously driving the multiple gear columns 24 to rotate, and then synchronously driving the first cooling fan blades 25 and the second cooling fan blades 26 on the multiple rotating rods 23 to rotate.

[0043] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0044] During use: by providing a battery protection box 1 on the outside of the battery pack body 7, the battery pack body 7 can be protected; during the driving process of the new energy vehicle, when the battery pack body 7 is subjected to the horizontal vibration force, the battery pack body 7 moves to the left or right, and when the multiple support wheels 9 on the bottom side of the frame 6 roll on the shock-absorbing support plate 4 and drive the frame 6 to move to the left, the first guide roller 12 on the two V-shaped plates 10 on the left side wall of the frame 6 generates a leftward force on the left end of the rubber transmission belt 14 sleeved on the four limiting rollers 16. At the same time, the right end of the rubber transmission belt 14 is subjected to the pulling force to generate a leftward force, causing the left end of the rubber transmission belt 14 to deform. At the same time, the tension of the rubber transmission belt 14 is transmitted to the right side wall of the frame 6. On the second guide roller 13, the leftward force of the frame 6 can be buffered and absorbed. Similarly, the rightward force of the frame 6 can also be buffered and absorbed, thereby absorbing the horizontal force of the battery pack body 7, reducing the influence of the horizontal force on the battery pack body 7; when the battery pack body 7 is subjected to the vertical vibration force, the multiple shock-absorbing springs 5 ​​on the bottom side of the shock-absorbing support plate 4 can achieve shock absorption of the vertical force of the battery pack body 7. In summary, with the cooperation of the two, the horizontal and vertical forces of the battery pack body 7 can be buffered and absorbed, thereby reducing the situation where the battery pack body 7 is easily damaged due to excessive vibration during the driving of the new energy vehicle.

[0045] When the frame 6 moves to the left or right due to vibration, the multiple groups of gear columns 24 are respectively meshed with the corresponding first rack 17 and second rack 18, thereby synchronously driving the multiple gear columns 24 to rotate, and then synchronously driving the first cooling fan blades 25 and second cooling fan blades 26 on the multiple rotating rods 23 to rotate, thereby accelerating the rapid circulation of air between the box chamber 2 and the outside world, so that the heat generated inside the battery protection box 1 is dissipated to the outside through the multiple top openings 19 and the multiple bottom openings 20, thereby achieving the heat dissipation effect in the battery protection box 1 and ensuring the normal operation of the battery pack body 7.

[0046] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
