Chinese patent document CN218491377U discloses a vehicle body lifting mechanism for automobile maintenance, including four fixed bottom plates, the tops of the four fixed bottom plates are all provided with support columns, and the opposite sides of the four support columns are all provided with slide grooves. The device can use the slide grooves and sliders on the support columns to drive the upper support plate and support frame plate to move up and down repeatedly by using the No. 1 hydraulic telescopic rod. The support frame plate allows the car to drive up, and the isolation plate and the partition plate on the No. 2 hydraulic telescopic rod can be used to fix and limit the position of the vehicle body, prevent dangerous things from happening, increase the height of the car, provide sufficient moving space for repair personnel, improve the repair efficiency of repair personnel, and avoid damage to the bottom of the car.

However, during the use of the device, since a hydraulic rod structure is provided at the bottom of the lifting mechanism, the support plate is at a certain height from the ground, and it is necessary to use tools such as ramps to allow the car to smoothly drive above the support plate, which is inconvenient to use. At the same time, the device sets a limiting structure for the car in the transverse direction but not in the longitudinal direction, so there is a risk of the car moving forward and backward on the support plate. The safety performance of the lifting mechanism during maintenance is not good. For this reason, an automobile maintenance lift is proposed.

The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

The present embodiment provides a car repair lift, as shown in Figures 1-3, including a limit assembly 20, the limit assembly 20 includes a motor 21, a screw rod 22, a slider 23, a slide rod 24, a limit block 25, a spring 26, a connecting block 27, a limit rod 28 and a sheath 29.

Among them, the output shaft of the motor 21 is fixedly connected to one end of the screw rod 22, the outer side wall of the screw rod 22 is threadedly connected with a slider 23, the inner side wall of the slider 23 is slidably connected with a slider 24, the top of the slider 24 is fixedly connected to a limiting block 25, the outer side wall of the slider 24 is sleeved with a spring 26, the top of the spring 26 is fixedly connected to the bottom of the slider 23, the bottom end of the slider 24 is fixedly connected with a connecting block 27, the bottom end of the spring 26 is fixedly connected to the top of the connecting block 27, one side of the connecting block 27 is fixedly connected to a limiting rod 28, and the outer side wall of the limiting rod 28 is fixedly connected with a sheath 29. During the lifting process, since the wheel is located in the through groove 16, the height of the vehicle body is partially lowered relative to the support plate 14, and the elastic force of the spring 26 prevents the limiting rod 28 and the chassis from being damaged or deformed due to excessive pressure between the limiting rod 28 and the chassis. The sheath 29 is made of elastic material and is also used to prevent the limiting rod 28 and the chassis from being squeezed against each other and damaged.

In this embodiment, specifically: a main body component 10 is arranged at the bottom of the limiting component 20, and the main body component 10 includes a bottom plate 11, a hydraulic column 12, a connecting bracket 13, a support plate 14, a baffle 15 and a through groove 16; four hydraulic columns 12 are symmetrically installed on the top of the bottom plate 11, and the connecting bracket 13 and the support plate 14 are driven to move upward through the operation of the hydraulic columns 12 to lift the car to a desired height.

In this embodiment, a connecting bracket 13 is fixedly connected to the top of the hydraulic column 12 .

In this embodiment, the motor 21 is installed on the top of the connecting bracket 13, and the screw rod 22 is rotatably connected to the inner wall of the connecting bracket 13. The motor 21 drives the screw rod 22 to rotate, so that the slider 23 moves upward, driving the limit rod 28 and the sheath 29 to contact the chassis of the car. At the same time, the two limit rods 28 are respectively located in front of the front wheel and behind the rear wheel to prevent the car from moving forward and backward. The slider 23 is slidably connected to one side of the connecting bracket 13.

A support plate 14 is fixedly connected to the bottom of the connecting bracket 13. The support plate 14 is used to support the car. When the lift is not lifted, the support plate 14 contacts the ground. By lowering the height of the support plate 14, it is convenient for the car to drive onto the lift.

In this embodiment, the upper surface of the support plate 14 is symmetrically fixedly connected with a baffle 15, which is arranged on both sides of the wheel to prevent the vehicle from sliding laterally and falling. The upper surface of the support plate 14 is provided with a through groove 16, and when the car is in place, the front and rear wheels are respectively located in the through groove 16.

The present embodiment provides a car repair lift, and its working process is as follows: fix the bottom plate 11 on the ground. When the lift is not lifted, the support plate 14 contacts the ground. By lowering the height of the support plate 14, it is convenient for the car to drive onto the lift without the aid of other tools. The operation is simple and convenient. After the car is in place, the front and rear wheels are respectively located in the through grooves 16. The motor 21 drives the screw rod 22 to rotate, so that the slider 23 moves upward, driving the limit rod 28 and the sheath 29 to contact the chassis of the car. At the same time, the two limit rods 28 are respectively located in front of the front wheel and behind the rear wheel to prevent the car from moving forward and backward. , limit structures are set in all horizontal directions to prevent the car from falling from the lift and improve the safety of the lift during maintenance. After the limit rod 28 is in place, the hydraulic column 12 works to drive the connecting bracket 13 and the support plate 14 to move upward and lift the car to the required height. During the lifting process, since the wheels are located in the through grooves 16, the height of the car body partially decreases relative to the support plate 14. The elastic force of the spring 26 prevents excessive pressure between the limit rod 28 and the chassis from causing damage or deformation of the chassis. After the car is lifted to a certain height, the maintenance personnel can repair the bottom of the car.

Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of this innovative technical solution.
