The extending end of the support beam 3 is slidably connected to the first bracket 1; near the bending portion 1013 and located on the first rod part 1011, the second rod portion 201 is connected between the two first rod portions 101 through a rotating shaft. In this structural design, the structure of the first bracket 1 and the connection relationship between the first bracket 1 and the second bracket 2 are further defined. The second rod part 1012 of the first rod portion 101 is bent downward to form a bending portion. This design enables the support beam 3 to maintain a sliding connection with the second bracket and can naturally maintain a horizontal state when the first bracket 1 and the second bracket 2 are cross-hinged, thereby significantly enhancing the stability and load-bearing capacity of the entire device.

[0040] As Figure 5 shown, a roller mounting bracket is hingedly connected to the top end of the bending portion 1013, and a roller assembly 13 is mounted on the roller mounting bracket. A rolling groove 301 is provided at one end of the support beam 3 connected to the bending portion 1013, and the roller assembly 13 is mounted in the rolling groove 301. Specifically, the roller mounting bracket includes a fixed rod 14 and a vertical connecting plate 1303. The fixed rod 14 is rotatably provided between the top ends of the first bracket 1 and the two first rod portions 101.

At this time, the universal wheel 16 and the aluminum cast wheel 12 are in the same horizontal straight line, which is convenient for maintenance personnel to push the lifting device; when the lifting device is in the highest rising state, the first connecting rod 9 plays a supporting role, and the rise of the first bracket 1 drives the universal wheel to rise.

[0045] like Figure 1 As shown, a support plate assembly 15 is detachably mounted on the support beam 3, and a plurality of support plate assemblies 15 can be mounted on the support beam 3. The support plate assembly 15 includes a support plate 1502 and a buckle 1501. The support plate 1502 is connected to the buckle 1501 by a pin shaft. The support plate 1502 is mounted on the support beam 3 by the buckle 1501. An anti-skid pad is provided on the upper surface of the support plate 1502, which can be a rubber or other material anti-skid pad. When in use, the support plate 1502 contacts the supporting part of the electric vehicle. As the electric vehicle is raised or lowered, the support plate 1502 can rotate to maintain good contact with the electric vehicle. The lifting device can easily adjust the electric vehicle to a tilt angle. This feature allows maintenance personnel to more conveniently repair certain specific parts of the electric vehicle, such as wheels and chassis, thereby improving maintenance efficiency and accuracy.

[0046] In this embodiment, the support plate assembly 15 can also adopt another structure, in which a top column is fixedly installed on the buckle 1501, so that the top column supports the corresponding part of the bottom of the electric vehicle when in use.

[0047] like Figures 1-3As shown, the outer side of the sliding inner rod 5 is provided with a plurality of first limiting holes, and an L-shaped connecting piece 501 is provided at the bottom of the sliding inner rod 5 and on the first frame rod 101. The outer side of the bottom of the sliding inner rod 5 is movably connected to the L-shaped connecting piece 501. Specifically, a through hole with a larger aperture can be provided on the L-shaped connecting piece 501. The bottom of the sliding inner rod 5 is connected to a positioning shaft, and the limiting shaft passes through the through hole on the L-shaped connecting piece 501. The aperture of the through hole is larger than the outer diameter of the positioning shaft, so that the positioning shaft has a certain range of motion relative to the through hole, and can move in the through hole in the up, down, left and right directions. The upper outer side of the vertical sleeve rod 401 of the sliding outer frame 4 is symmetrically provided with a grip rod 6, and the lower outer side of the vertical sleeve rod 401 is provided with at least one second limiting hole matching the first limiting hole, and a limiting rod 7 is detachably provided on the second limiting hole.

[0049] A rotating column is provided at the bottom end of the first frame rod 101 and between the two first frame rods 101, and a second connecting seat 17 is provided on the rotating column. The lifting cylinder is vertically installed on the second connecting seat 17, and the telescopic end of the lifting cylinder 8 is connected to the horizontal top rod 402. Pressure relief rods 802 and foot-operated pressure rods 801 are provided on both sides of the bottom of the lifting cylinder 8, which can easily control the height of the lifting device.

[0050] The usage process is as follows:

[0051] When in use, find the part that needs repair and the lifting device should be in the following position: Figure 3 In the initial state shown in FIG. 1 , push the lifting device under the chassis of the electric vehicle. Figure 2 As shown, the maintenance personnel hold the handle 6 and continuously step on the foot-operated pressure rod 801. The telescopic rod of the lifting cylinder 8 extends upward to make the sliding outer frame 4 rise along the movable inner rod 5. The sliding outer frame 4 drives the first bracket 2, the second bracket 2 and the support beam 3 to rise. At the same time, the support plate 1502 installed on the support beam 3 through the snap member 1501 supports the supporting part of the electric vehicle. After reaching the appropriate lifting height, the sliding outer frame 4 is fixed through the limit rod 7, and the first bracket 1 and the second bracket 2 are locked, which is convenient for maintenance and other operations, and convenient for repairing certain specific parts of the electric vehicle, such as wheels, chassis, etc. After the maintenance of the electric vehicle is completed, the pressure is released by stepping on the pressure relief rod 802, and the lifting device returns to the position as shown. Figure 3 In the initial state shown, push the lifting device to the appropriate position.

[0052] This embodiment is applicable to the maintenance of electric vehicles, including but not limited to electric bicycles, electric tricycles, and small and micro electric vehicles. In fact, it is also applicable to the maintenance of two-wheeled and three-wheeled motorcycles and small and micro fuel vehicles.

[0053] In summary, for the lifting device for repairing electric vehicles of the present utility model, maintenance personnel can easily adjust the height and position of the device without complex operation steps, which not only reduces the operation difficulty but also improves the maintenance efficiency. At the same time, due to the simple structure and moderate cost of the device, it is more easily popularized and applied in the electric vehicle maintenance industry.
