[0001] The present invention relates to the technical field of maintenance platforms, and in particular to a new energy vehicle maintenance platform. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source and integrate advanced technologies in vehicle power control and drive to form advanced technical principles, new technologies, and new structures. When a new energy vehicle breaks down, it needs to be sent to a corresponding maintenance platform for repair, so that the maintenance platform can lock the four wheels of the vehicle to prevent instability during vehicle maintenance, and at the same time, the vehicle can be raised to facilitate maintenance of the vehicle chassis. This can avoid the difficulty of manually controlling the height of the vehicle due to its large size and weight, thereby improving the convenience of maintenance or daily maintenance of new energy vehicles with the cooperation of the maintenance platform.

The positioning mechanism and the clamping mechanism are relatively cumbersome to operate, which increases the workload of the staff and affects the efficiency of vehicle maintenance. Summary of the invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art and to propose a new energy vehicle maintenance platform.

[0015] Compared with the prior art, the present invention provides a new energy vehicle maintenance platform, which has the following beneficial effects: 1. The new energy vehicle maintenance platform enables the unloading buffer component to work by moving the vehicle wheel in the wheel groove. When the unloading buffer component works, the self-positioning limiting component is driven by the transmission component to realize automatic position limiting of the vehicle wheel, thereby preventing the vehicle from shaking during the maintenance process. The operation is simple and the vehicle maintenance efficiency is effectively improved.

[0016] 2. After the vehicle maintenance is completed, the new energy vehicle maintenance platform lowers the wheel seat through the hydraulic cylinder so that the wheel seat abuts against the base, automatically releasing the restriction of the self-positioning restriction component on the rear wheels of the vehicle.

[0025] Furthermore, the transmission component includes a support plate 5 fixed on the limit seat 4, a rotating rod 501 rotatably connected to the support plate 5, a reel 502 and a driven gear 503 arranged on the rotating rod 501, and a pull rope 504 wound around the reel 502, the end of the pull rope 504 away from the reel 502 is connected to the self-positioning limiting component, and a rack plate 4011 meshing with the driven gear 503 is provided on the slide plate 401.

[0026] Furthermore, the self-positioning limiting assembly includes a fixed seat 6 fixed on the bottom side of the wheel seat 302, a rotating rod 601 rotatably connected to the fixed seat 6, a limiting plate 602 arranged on the rotating rod 601, a sliding seat 7 slidably connected to the fixed seat 6, and a supporting plate 701 movably connected to the sliding seat 7 and the limiting plate 602, a sliding block 702 is fixed to the bottom of the sliding seat 7, a sliding groove 603 for sliding of the sliding block 702 is provided on the fixed seat 6, an elastic element 6031 is provided between the inner wall of the sliding groove 603 and the sliding block 702, and a movable groove 8 for the movement of the limiting plate 602 is provided in the wheel groove 3021.

[0027] Furthermore, a guide member 9 is fixedly provided at the bottom of the wheel seat 302 , and one end of the pull rope 504 away from the reel 502 passes through the guide member 9 and is connected to the slide seat 7 .

[0028] Furthermore, the self-positioning limiting component also includes an elastic telescopic rod 703 arranged in the sliding seat 7, and the fixed seat 6 has equidistantly distributed holes 10 along its length direction. The elastic telescopic rod 703 is inserted into the hole 10, and the end of the elastic telescopic rod 703 is provided with an extrusion slope.

[0029] Furthermore, a top rod 11 is fixedly provided on the top of the base 1 , and the top rod 11 is inserted into the insertion hole 10 and movably abuts against the elastic telescopic insertion rod 703 .

[0030] Furthermore, the bottom wall of the wheel groove 3021 is inclined, and the lower end of the bottom wall of the wheel groove 3021 is placed on the lower side of the limiting seat 4.

[0031] Furthermore, an inclined guide block 12 is provided at the front end of the base 1, and the inclined guide block 12 is fixed on the ground.

[0032] Specifically, the car enters the wheel seat 302 through the inclined guide block 12, and the wheel moves along the wheel groove 3021 of the wheel seat 302 until the car wheel abuts against the arc plate 402. The arc plate 402 is forced to drive the slide plate 401 to move toward the limit seat 4. During this period, the rack plate 4011 on the slide plate 401 is meshed with the driven gear 503. The driven gear 503 drives the reel 502 to rotate through the rotating rod 501. The reel 502 releases the pull rope 504 so that the pull rope 504 no longer exerts force on the slide seat 7. The tension is added, and the slide 7 is reset under the pull of the stretched elastic element 6031, and the slide 7 moves toward the rotating rod 601. The slide 7 pushes the limit plate 602 upward through the support plate 701, so that the limit plate 602 abuts against the wheel of the car placed at the front end of the wheel groove 3021. At this time, the elastic telescopic rod 703 on the slide 7 is aligned with one of the sockets 10 on the fixed seat 6. Then, by controlling the operation of the hydraulic cylinder 201, the piston rod of the hydraulic cylinder 201 drives the wheel seat 302 to move upward, and the wheel seat 302 When moving upward, the lifting seat 3 is separated from the base 1, so that the top rod 11 moves out of the insertion hole 10, and the elastic telescopic insertion rod 703 is automatically inserted into the insertion hole 10 to limit the position of the sliding seat 7, thereby maintaining the limit plate 602 in contact with the wheel, so that the wheels at both ends of the car are respectively in contact with the arc plate 402 and the limit plate 602. It should be noted that, since the inner wall of the bottom of the wheel groove 3021 is inclined, the car will not move toward the front end of the wheel groove 3021 when moving upward with the lifting seat 3, thereby ensuring that the limit plate 60 2 is in a tight state with the wheel; after the maintenance of the car is completed, the wheel seat 302 is lowered by the hydraulic cylinder 201, so that the wheel seat 302 is in contact with the base 1, and the push rod 11 is inserted into the socket 10 to shrink the elastic telescopic plug rod 703. The position of the slide seat 7 is no longer restricted, and the car can directly move along the wheel groove 3021 and press the limit plate 602 to move out, automatically releasing the restriction of the self-positioning limit assembly on the rear wheel of the car, without other operations by the staff, reducing the workload of the staff and improving the efficiency of car maintenance.
