[0021] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0022] All components of this utility model are general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0023] See Figure 1-4 This is a schematic diagram of the structure of the present utility model. An embodiment of the present utility model provides a wheel limiting structure for the maintenance of new energy vehicles, including a cavity box 1. A square opening 8 is provided on one side of the cavity of the cavity box 1, and a cross-shaped opening 9 is provided on the other side of the cavity of the cavity box 1. There are two square openings 8 and two cross-shaped openings 9, and they are symmetrically distributed on both sides with the center line of the cavity box 1 as the center.

[0024] A first electric push rod 10 is installed inside the cavity of the cavity housing 1. A first bracket 11 is installed on the output end of the first electric push rod 10. A first baffle 12 is installed at both ends of the first bracket 11. The first baffle 12 is placed inside the square opening 8.

[0025] A second electric push rod 13 is installed on the first bracket 11. An ear plate 14 is installed on the output end of the second electric push rod 13. A second bracket 15 is installed on the ear plate 14. The two sides of the second bracket 15 are respectively placed in the cross-shaped opening 9. A second baffle 16 is installed on the two sides of the second bracket 15. The second baffle 16 is respectively placed in the cross-shaped opening 9.

[0026] It should be noted that in this embodiment, the cavity box 1 is made of hard steel, with a wall thickness of 20-30cm, which is sufficient to support the weight of the new energy vehicle. The first electric push rod 10 and the second electric push rod 13 both operate in energy-saving mode and are manually controlled by external limit switches. The height ratio of the first baffle 12 to the second baffle 16 is 2:1, and their tops are on the same horizontal line. Their widths are twice the width of the wheel, and the distance between them is greater than the distance between the front and rear wheels of the vehicle.

[0027] Specifically, during use, when repairing a new energy vehicle, the vehicle is driven onto the cavity housing 1, and the first electric push rod 10 is manually controlled to move, causing the first bracket 11 to move the first baffle 12 upward within the cavity housing 1. The first baffle 12 extends out of the square opening 8, and at the same time, it causes the second baffle 16 on the second bracket 15 to extend out of the cross-shaped opening 9. The staff adjusts the vehicle so that the front wheels are against the first baffle 12. At this time, the second electric push rod 13 is manually controlled to move the second bracket 15 along the cross-shaped opening 9 towards the first baffle 12 through the ear plate 14, so that the second baffle 16 is against the rear wheel of the vehicle. This can limit the movement of the four wheels of the vehicle and avoid the danger of the vehicle rolling away during repair (the driver can precisely drive the vehicle wheels to the position of the first baffle 12).

[0028] The first baffle 12 is provided with a first mounting groove 19, and a first rubber plate 20 is installed in the first mounting groove 19. The second baffle 16 is provided with a second mounting groove 21, and a second rubber plate 22 is installed in the second mounting groove 21.

[0029] The first bracket 11 has a groove 17, and the second bracket 15 has a horizontal plate 18 installed in the groove 17.

[0030] A maintenance trench 2 is provided on the cavity box 1, and a step plate 3 is installed in the maintenance trench 2;

[0031] The side cavity of the cavity box 1 is provided with an inspection port 4, and a rotating door 5 is installed inside the inspection port 4 by means of a hinge.

[0032] An outer ground 6 is provided outside the cavity box 1, and a trench 7 is dug inside the outer ground 6. The cavity box 1 is buried in the trench 7.

[0033] It should be noted that, in this embodiment, the inward surfaces of the first rubber plate 20 and the second rubber plate 22 are respectively processed with "Z" shaped patterns;

[0034] The horizontal plate 18 plays a balancing role in the movement of the second bracket 15, and the vertical and horizontal gap between the horizontal plate 18 and the groove 17 is 0.1-0.2mm.

[0035] The depth of inspection trench 2 is between 160-170cm, suitable for the height of maintenance personnel;

[0036] The outer ground 6 is a horizontal ground, while the cavity box 1 is level with the ground plane, which facilitates the entry and exit of wheels.

[0037] Specifically, during use, a trench 7 is dug on the outer ground 6, and the hollow box 1 is lowered in and filled to make the hollow box 1 level with the ground. When the wheel contacts the first baffle 12 and the second baffle 16, it contacts the first rubber plate 20 and the second rubber plate 22. The first rubber plate 20 and the second rubber plate 22 protect the wheel and prevent slippage, avoiding wear during wheel positioning. When the second bracket 15 moves, the cross plate 18 moves in the groove 17, making the second baffle 16 move stably. The rotating door 5 is opened, and the staff can enter the cavity of the hollow box 1 through the inspection port 4 to inspect the internal structure and equipment.

[0038] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0039] The working process and principle of this utility model are as follows: When using this utility model to repair a new energy vehicle, the vehicle is driven onto the cavity box 1. The first electric push rod 10 is manually controlled to push the first bracket 11 to move the first baffle 12 upward within the cavity of the cavity box 1. The first baffle 12 extends out of the square opening 8, and at the same time, it drives the second baffle 16 on the second bracket 15 to extend out of the cross-shaped opening 9. The staff adjusts the vehicle so that the front wheels are against the first baffle 12. At this time, the second electric push rod 13 is manually controlled to move the second bracket 15 along the cross-shaped opening 9 towards the first baffle 12 through the ear plate 14, so that the second baffle 16 is against the rear wheel of the vehicle. This can limit the movement of the four wheels of the vehicle and avoid the danger of the vehicle rolling away during repair.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
