A centering vertical pipe is fixedly connected above the centering fixing frame. By respectively pushing against the left and right tires of the automobile and moving inwards through the left and right centering vertical pipes, since the two centering tooth columns move inwards synchronously, when the centering vertical pipes on both sides are finally clamped on the tires, the automobile is located in the exact middle position. At the same time, a roller conveyor belt is provided, and the rotation direction of the rollers on the roller conveyor belt is the same as the direction in which the tire is pushed, making it easier to push the automobile. Meanwhile, a tensioning plate is provided on the centering vertical pipe, and by detecting the pressure change of the inward pressure applied to the tensioning plate, it is judged whether the tire has been touched. When the tires are detected by the tensioning plates on both sides, it indicates that the centering is completed, realizing automatic centering.

[0059] Embodiment Two:

[0060] This embodiment provides a vehicle centering device, which has the following technical features in addition to the technical solutions of the above embodiment.

[0061] Please refer to Figure 8 , at least two centering devices 2 are arranged front and rear on a vehicle carrier plate 91, wherein the width of the roller conveyor belt 26 on the rear centering device 2 is greater than the width of the roller conveyor belt 26 on the front centering device 2, and the length of the centering vertical pipe 25 on the rear centering device 2 is greater than the length of the centering vertical pipe 25 on the front centering device 2, so as to adapt to vehicles of different lengths.

[0062] Specifically, since the length of the centering vertical pipe 25 is too long, when the tire is not pressed against the middle position of the centering vertical pipe 25, the two sides of the centering fixing frame 23 connected to the centering tooth column 22 are unevenly stressed, resulting in easy damage to the structure. To solve this problem, the connecting plate 234 is slidably connected to the centering fixing frame 23;

[0063] The centering support plate 212 is slidably connected to the vehicle carrier plate 91, and the centering support plate 212 is connected with a push rod, and the push rod is driven by a motor to push the centering support plate 212 to slide on the vehicle carrier plate 91;

[0064] The tensioning plate 251 is divided into multiple tensioning sub-plates 2511, and the back of each tensioning sub-plate 2511 is sequentially connected with a pressure ejector rod 252, a pressure sleeve 253, a pressure bottom plate 254, a pressure sensor 255 and a rear mounting box 256;

[0065] The position of the tire is identified through multiple tensioning sub-plates 2511, thereby pushing the centering support plate 212 to slide on the vehicle carrier plate 91, so that the connecting plate 234 slides to the position corresponding to the tire.

[0066] To sum up, for this vehicle centering device, by setting the centering drive motor 21 to drive the centering gear shaft 211 to rotate, the centering gear shaft 211 meshes with the centering tooth columns 22 on both sides, so that the two centering tooth columns 22 move towards each other, thereby driving the two centering fixing frames 23 on both sides to slide inwards synchronously. A centering vertical pipe 25 is fixedly connected above the centering fixing frame 23. By moving inwards with the left and right centering vertical pipes 25 respectively pressing against the left and right tires of the vehicle, since the two centering tooth columns 22 move inwards synchronously, when the centering vertical pipes 25 on both sides are finally clamped on the tires, the vehicle is located in the middle position. At the same time, a roller conveyor belt 26 is provided, and the rotation direction of the rollers on the roller conveyor belt 26 is the same as the direction in which the tire is pushed, making it easier to push the vehicle. At the same time, a tensioning plate 251 is provided on the centering vertical pipe 25, and whether the tire has been pressed against is judged by detecting the pressure change of the tensioning plate 251 pressing inwards. When the tires are detected by the tensioning plates 251 on both sides, it indicates that the centering is completed, realizing automatic centering.

[0067] The vehicle centering device is provided with at least two centering devices 2, front and rear, on a vehicle-carrying plate 91. The width of the rear roller conveyor 26 is greater than that of the front roller conveyor 26, and the length of the rear centering vertical pipe 25 is greater than that of the front centering vertical pipe 25. After the front wheels of the vehicle stop on the front roller conveyor 26, the rear wheels of vehicles of different lengths can all stop on the rear roller conveyor 26, thus adapting to vehicles of different lengths.

[0068] In the vehicle centering device, the connecting plate 234 is slidably connected to the centering fixing frame 23, the centering support plate 212 is slidably connected to the vehicle-carrying plate 91, a push rod is connected to the centering support plate 212, and the tensioning plate 251 is divided into multiple tensioning sub-plates 2511. Pressure sensing devices are sequentially connected to the back of each tensioning sub-plate 2511. The positions of the tires are identified by the multiple tensioning sub-plates 2511, thereby pushing the centering support plate 212 to slide on the vehicle-carrying plate 91, so that the connecting plate 234 slides to the position corresponding to the tire. When the length of the centering vertical pipe 25 is too long and the tire does not top the middle position of the centering vertical pipe 25, the problem of uneven force on both sides of the centering fixing frame 23 connected to the centering tooth column 22, which may cause easy damage to the structure, is avoided, and the durability of the device is improved.

[0069] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.

[0070] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
