[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5As shown, this utility model provides a vehicle lifting device for automobile maintenance, including a base 1. A lifting seat 2 is movably connected to the middle of the upper surface of the base 1. Wheel brackets 3 are movably connected to the left and right sides of the upper surface of the lifting seat 2. There are two wheel brackets 3. Side baffles 4 are fixedly connected to the upper surface of each wheel bracket 3. Fixing plates 9 are fixedly connected to the outer surface of each wheel bracket 3. Limiting rods 10 are movably sleeved on the outer surface of the fixing plates 9. The lower surface of the limiting rods 10 is fixedly connected to the upper surface of the lifting seat 2. A first motor 5 is fixedly installed on the inner surface of the middle part of the lifting seat 2. A round shaft 6 is fixedly sleeved at the other end of the output shaft of the first motor 5. An active rod 7 located between the two wheel brackets 3 is fixedly sleeved on the outer surface of the round shaft 6. A driven rod 8 is hinged to both ends of the active rod 7. There are two driven rods 8. The other ends of the two driven rods 8 are respectively hinged to the outer surfaces of the two wheel brackets 3.

[0023] When motor 5 is running, the circular shaft 6 and the drive rod 7 will start to rotate. At this time, the two ends of the drive rod 7 will drive the two driven rods 8, causing the two driven rods 8 to start rotating. At the same time, the other ends of the two driven rods 8 will also drive the wheel frame 3, causing the wheel frame 3 to move as a whole.

[0024] Among them, the outer surfaces of the left and right sides of the lifting seat 2 are hinged to a first hinge block 12. The lower side of the outer surface of the first hinge block 12 is fixedly connected to a first pneumatic cylinder 13. The lower side of the outer surface of the first pneumatic cylinder 13 is fixedly sleeved with a second hinge block 14. The second hinge block 14 is hinged to the outer surfaces of the left and right sides of the base 1.

[0025] When the No. 1 pneumatic cylinder 13 is running, the top of the No. 1 pneumatic cylinder 13 will push the No. 1 hinge block 12, causing the No. 1 hinge block 12 and the lifting seat 2 to move as a whole.

[0026] Among them, the left and right sides of the upper surface of the lifting seat 2 are movably sleeved with fixing posts 11. The bottom end of the fixing post 11 passes through the lifting seat 2 and extends to the upper surface of the base 1 and is fixedly connected to the base 1.

[0027] The design of the fixed column 11 serves to restrict the overall movement direction of the lifting seat 2.

[0028] Among them, the bottom ends of the two wheel frames 3 are fixedly installed with a second pneumatic cylinder 16. The top end of the second pneumatic cylinder 16 passes through the wheel frame 3 and extends into the interior of the wheel frame 3 and is fixedly connected to a movable plate 15. The outer surface of the movable plate 15 is movably connected to the inner surface of the wheel frame 3.

[0029] The operation of the second pneumatic cylinder 16 will cause the moving plate 15 to begin moving up and down inside the wheel frame 3.

[0030] Among them, a second motor 17 is fixedly installed in the middle of the lower surface of the movable plate 15, and a rotating shaft 18 is fixedly sleeved at the other end of the output shaft of the second motor 17. The top end of the outer surface of the rotating shaft 18 passes through the movable plate 15 and extends to the top of the movable plate 15, and a gear 19 is fixedly sleeved thereon.

[0031] When motor 17 is running, the rotating shaft 18 and gear 19 will begin to rotate.

[0032] Among them, gear 19 has toothed plates 20 meshing with both sides of its outer surface. The outer ends of the toothed plates 20 are fixedly connected to wheel blocks 21 located inside the wheel frame 3. There are four wheel blocks 21, and the outer surfaces of the four wheel blocks 21 on the left and right sides are movably connected to the inner surfaces of the two wheel frames 3 respectively.

[0033] The rotation of gear 19 will drive gear plate 20 and abutment block 21, causing the four abutment blocks 21 to start moving in opposite directions.

[0034] Among them, the outer surfaces of the front and rear sides of the lifting seat 2 are fixedly connected with ramp plates 23, the outer surfaces of the ramp plates 23 are movably connected to the outer surfaces of the two wheel frames 3 respectively, and the inner surfaces of the two wheel frames 3 are fixedly connected with T-blocks 22, the outer surfaces of the T-blocks 22 are movably connected to the outer surfaces of the toothed plates 20.

[0035] The design of the ramp 23 facilitates the vehicle's movement onto the two wheel supports 3.

[0036] Working principle and usage process of this utility model:

[0037] First, the operator starts motor 5. As motor 5 runs, the shaft 6 and the drive rod 7 begin to rotate. The rotation of the drive rod 7 drives the two driven rods 8, causing them to rotate around the two ends of the drive rod 7. At the same time, the other ends of the two driven rods 8 drive the two wheel carriers 3, causing them to move in opposite directions under the control of the fixed plate 9 and the limiting rod 10. This changes the distance between the two wheel carriers 3 until the distance between the two side baffles 4 is the same as the wheel track of the maintenance vehicle.

[0038] Then, the operator drives the vehicle onto the two wheel supports 3. After the vehicle comes to a stop, the operator starts the second pneumatic cylinder 16 and the second motor 17. The operation of the second pneumatic cylinder 16 causes the moving plate 15 to move upward. During this process, the four wheel abutment blocks 21 gradually move between the four wheels. The operation of the second motor 17 causes the rotating shaft 18 and gear 19 to start rotating. The rotation of gear 19 drives the gear plate 20, causing the four wheel abutment blocks 21 to move in opposite directions along the inner surface of the wheel support 3. Finally, when all four wheel abutment blocks 21 are in contact with the vehicle wheels, the vehicle will be unable to move due to the presence of the wheel abutment blocks 21 and the side baffle 4, thus ensuring that the vehicle will not move during maintenance.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
