Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor vehicle maintenance technology, specifically to a lifting device for motor vehicle maintenance. Background Technology
[0002] Motor vehicle maintenance refers to the maintenance work that must be performed on time when road transport vehicles reach the mileage or interval stipulated by the relevant national regulations. During the maintenance process, the motor vehicle needs to be lifted so that the staff can conduct a comprehensive inspection of the motor vehicle.
[0003] Existing vehicle maintenance lifts lack a stable support structure in practical use, making them prone to swaying of both the lift and the vehicle during maintenance, posing a safety hazard. Furthermore, existing lifts have a height difference from the ground, requiring a dedicated ramp for vehicle movement, which is inconvenient. Additionally, insufficient lighting hinders chassis maintenance, further complicating the process.
[0004] To address the aforementioned technical issues, a lifting platform for motor vehicle repair, as disclosed in CN220827187U, uses a lifting motor to drive a lifting screw to rotate, thereby enabling the lifting block to move vertically. This, in turn, causes the lifting plate and the vehicle to be repaired to move vertically. The lifting plate supports the motor vehicle, and a stable support structure is formed by horizontal support rods and longitudinal connecting rods to support the lifting plate.
[0005] The aforementioned patent also has the following shortcomings: the existing lifting equipment has low lifting stability due to single-sided driving, and the car cannot be locked again after lifting, which can easily lead to situations where the car does not apply the brakes or the brakes are lost, causing it to slip. Utility Model Content

A cylinder is rotatably connected to the middle of the inner cavity of the base, and the output end of the cylinder is rotatably connected to the inner side of the first movable rod.
[0012] Preferably, the load-bearing component includes a top support seat, which is rotatably connected to the top end of the first movable rod, and inclined plates are fixedly installed at both ends of the top support seat.

Detailed Implementation
[0025] 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.
[0026] This utility model provides a lifting device for motor vehicle maintenance, including a connecting rod 1:
[0027] Both ends of the connecting rod 1 are provided with lifting mechanisms 2 for raising and lowering the motor vehicle, and the top of the outer side of the lifting mechanism 2 is provided with a limiting mechanism 3 for pressing the motor vehicle tires together.
[0028] The lifting mechanism 2 includes a support component and a load-bearing component. The support component is located at both ends of the connecting rod 1, and the load-bearing component is located at the top of the support component.
[0029] The vehicle is supported and lifted through the cooperation of support components and load-bearing components.
[0030] The limiting mechanism 3 includes a first pushing component, a support component, a transmission component, and a second pushing component. The first pushing component is located on the outside of the bearing component, the support component is located on top of the first pushing component, the transmission component is located inside the support component, and the second pushing component is located on top of the support component.
[0031] The first pushing component, the support component, the transmission component, and the second pushing component work together to clamp and lock the rear wheels of the vehicle before lifting, thus preventing slippage.
[0032] Preferred:
[0033] like Figure 2 As shown, the support assembly includes a base 21, which is fixedly installed at both ends of the connecting rod 1. One end of the inner cavity of the base 21 is rotatably connected to a first movable rod 23, and the other end of the inner cavity of the base 21 is rotatably connected to a second movable rod 24. A cylinder 22 is rotatably connected to the middle of the inner cavity of the base 21, and the output end of the cylinder 22 is rotatably connected to the inner side of the first movable rod 23. The support assembly is raised and lowered by means of cross extension and folding.
[0034] like Figure 2 As shown, the load-bearing component includes a top support 25, which is rotatably connected to the top of the first movable rod 23. Both ends of the top support 25 are fixedly installed with inclined plates 26, so as to simultaneously support both sides of the motor vehicle and facilitate its entry and exit.
[0035] When lifting, the vehicle is first positioned on top of the two sets of top support seats 25. At this time, the rear wheels of the vehicle are clamped and locked by the limiting mechanism 3, and then it can be lifted. The cylinder 22 directly pushes the first movable rod 23 and the second movable rod 24 to rotate at one end and roll at the other end. The difference in the angle changes, thereby lifting the top support seat 25 and the vehicle on top of it. This can achieve the lifting operation, which is the state shown in the figure.
[0036] further:
[0037] like Figure 3 As shown, the first pushing component includes a fixing plate 31, which is fixedly installed on the outside of the top support 25. A first electric push rod 32 is fixedly installed on the outside of the fixing plate 31, and a push seat 33 is fixedly installed on the output end of the first electric push rod 32, thereby realizing the function of position adjustment.
[0038] like Figure 4 As shown, the support assembly includes a connecting box 34, which is fixedly installed on the top of the push base 33. A gear 35 is rotatably connected to the bottom of the inner cavity of the connecting box 34, which can provide auxiliary support and auxiliary transmission.
[0039] like Figure 4As shown, the transmission assembly includes a toothed plate 36, which is meshed with the outside of the gear 35. The toothed plate 36 slides inside the connecting box 34. A crossbar 37 is fixedly installed on one end of the toothed plate 36. When force is applied, tooth transmission can be achieved, thereby achieving a clamping effect.
[0040] like Figure 4 As shown, the second pushing component includes a connecting block 38, which is fixedly installed on the top of one end toothed plate 36. The connecting block 38 slides through the top of the connecting box 34. A second electric push rod 39 is fixedly installed on the top of the connecting box 34. The output end of the second electric push rod 39 is fixed to the connecting block 38, which can realize the power output pushing effect during the clamping process.
[0041] When clamping is required, the first electric push rod 32 pushes the push base 33 to move the connecting box 34 and its internal components together. At this time, the crossbar 37 is located on the outside of the rear wheel of the vehicle. Then, the second electric push rod 39 pushes the connecting block 38 to move one set of toothed plates 36. When it moves, it meshes and drives the gear 35 to rotate. The gear 35 will then mesh and drive the other set of toothed plates 36 to move until the two sets of crossbars 37 move inward in sync, thereby clamping and limiting the rear wheel of the vehicle, preventing slippage and improving safety during maintenance.
[0042] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
