Technical Field

[0001] The present invention relates to the technical field of vehicle lifting devices, and particularly to a vehicle lifting device. Background Art

[0002] Automobiles, one of the greatest inventions of the 20th century, have profoundly changed the way of human life. As a means of transportation integrating various high-tech fields such as machinery, electronics, and chemical engineering, automobiles not only provide people with convenient and fast travel methods but also become an indispensable part of modern society. In terms of appearance, automobiles have a streamlined body design, which is not only beautiful and generous but also can effectively reduce air resistance and improve driving efficiency. Inside the body, there are comfortable seats, advanced audio systems, and intelligent driving assistance devices, providing a pleasant riding experience for passengers and drivers. During the automobile production process, it is often necessary to lift and transport automobiles through lifting devices.

[0003] In the prior art, when using a lifting device to carry out lifting operations on an automobile, the four support points of the vehicle body are supported by the lifting device. However, the lifting device is often a fixed structure and cannot flexibly adjust the positions of the support points according to the differences in the lengths of the vehicle bodies, thus restricting the adaptability and flexibility of the lifting operations. In addition, relying solely on four support points to support the entire vehicle body, the stability of the automobile is relatively poor. Therefore, it is necessary to propose a vehicle lifting device to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a vehicle lifting device, which has the characteristics of being able to match vehicle bodies of different lengths to improve the adaptability and flexibility of lifting operations and to improve the lifting stability.

[0005] To achieve the above object, the present invention provides the following technical solution: A vehicle lifting device includes a vehicle body and a connecting member. A U-shaped frame is installed at the lower end of the connecting member. A bidirectional lead screw is rotatably connected inside the U-shaped frame. Two symmetrically distributed connecting bars are threadedly connected to the outer wall of the bidirectional lead screw. Vertical plates are fixedly connected to the lower ends of the two connecting bars. Electric telescopic rods are installed at the front ends of the two vertical plates. The output ends of the two electric telescopic rods respectively penetrate through the two vertical plates and are fixedly connected with sliding blocks. First load-bearing arms are fixedly connected to the lower ends of the two sliding blocks. First arc-shaped support blocks are fixedly connected to the opposite sides of the two first load-bearing arms.

[0006] Second load-bearing arms are fixedly connected to the lower ends of the two connecting bars and are located behind the two sliding blocks. Second arc-shaped support blocks are fixedly connected to the opposite sides of the two second load-bearing arms.

[0007] In order to improve the anti-slip effect when the arc surfaces of the two first arc support blocks and the two second arc support blocks come into contact with the vehicle body, as an optimization of the vehicle hoist of the present invention, anti-slip layers are provided on the arc surfaces of the two first arc support blocks and the two second arc support blocks.

[0008] In order to facilitate improving the stability of the movement of the two connecting bars, as an optimization of the vehicle hoist of the present invention, two sliding rods that penetrate through the connecting bars and are slidably connected to them are fixedly connected inside the U-shaped frame.

[0009] In order to improve the stability of the sliding of the two sliding blocks, as an optimization of the vehicle hoist of the present invention, the two sliding blocks are respectively slidably connected to the lower ends of the two connecting bars through slide rails.

[0010] In order to facilitate further stabilizing the installation of the two first arc support blocks and the two second arc support blocks, as an optimization of the vehicle hoist of the present invention, reinforcing plates are fixedly connected to the lower ends of the two first load-bearing arms and the two second load-bearing arms, and the four reinforcing plates are respectively fixedly connected to the lower ends of the two first arc support blocks and the two second arc support blocks.

[0011] In order to facilitate driving the rotation of the bidirectional lead screw, as an optimization of the vehicle hoist of the present invention, a stepping motor with an output end fixedly connected to the bidirectional lead screw is installed on the outer wall of the U-shaped frame.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] When the two electric telescopic rods are started, the distance between the first arc support block and the second arc support block will increase or decrease until the distance is adjusted to an appropriate state according to the parameters of the vehicle body, so as to match vehicle bodies of different lengths, thereby achieving the purpose of improving the adaptability and flexibility of the lifting operation;

[0014] When the arc surfaces of the two first arc support blocks and the two second arc support blocks are in contact with the bottom surface and the side surface of the vehicle body, the bottom surface of the vehicle body can be supported at four points, and at the same time, a certain pressing force is provided to the side surface of the vehicle body, thereby achieving the purpose of improving the lifting stability.
