During vehicle inspection, a comprehensive inspection of the vehicle's chassis, suspension system, tires, and other undercarriage and hidden components is required. Traditional manual inspection methods, involving bending over or using simple tools, are not only inefficient but also present blind spots and operational safety hazards. Vehicle inspection lifting platforms have emerged to address this need. By smoothly lifting the vehicle to a suitable height, they provide inspectors with ample operating space, making the undercarriage components clearly visible, effectively solving the shortcomings of traditional inspection methods.

[0003] In the existing technology, the lifting frame for vehicle inspection adopts a relatively complex transmission method, such as hydraulic cylinder combination or linkage mechanism. The number and types of parts are large, which increases the time and cost of material procurement, parts processing and assembly debugging in the manufacturing process. At the same time, the complex structure is prone to shaking and jamming during long-term use. Utility Model Content

[0024] 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.

[0025] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a lifting frame for automobile inspection, comprising a movable plate 1 and a U-shaped plate 9. A fixing block 2 is fixedly connected to the upper surface of the movable plate 1. A motor 3 is fixedly connected to the outer wall of the fixing block 2. The output end of the motor 3 is rotatably connected to the inside of the fixing block 2 and fixedly connected to a threaded rod 4. The outer wall of the threaded rod 4 is rotatably connected to the inside of the fixing block 2. An internal threaded slider 5 is threadedly connected to the outer wall of the threaded rod 4. A sliding column 6 is slidably connected to the inside of the internal threaded slider 5. The outer wall of the sliding column 6 is fixedly connected to the inside of the fixing block 2. A fixing block 7 is fixedly connected to the upper surface of the internal threaded slider 5. A sliding column 8 is fixedly connected to the outer wall of the fixing block 7. A groove 10 is provided on the outer wall of the U-shaped plate 9. The outer wall of the sliding column 8 is slidably connected to the inner wall of the groove 10. A rotating column 11 is rotatably connected to the inside of the U-shaped plate 9. A detection carrier plate 12 is fixedly connected to the top of the rotating column 11. A limit assembly is provided on the upper surface of the movable plate 1.

[0026] Specifically, the fixing block 2 is used to fix the motor 3 and also to support the slide column 6. The slide column 6 is used to limit and guide the internal thread slider 5. During the movement of the internal thread slider 5, the inside of the internal thread slider 5 will slide on the outer wall of the slide column 6. The motor 3 is used to provide output. When the motor 3 starts, the output end of the motor 3 will rotate inside the fixing block 2 and drive the threaded rod 4 to rotate inside the fixing block 2. The rotation of the threaded rod 4 will cause the internal thread slider 5 to move. The movement of the internal thread slider 5 will drive the slide column 8 to move and slide on the inner wall of the inclined groove 10 opened on the outer wall of the U-shaped plate 9, thereby causing the U-shaped plate 9 to move up and down, and thus causing the detection carrier plate 12 to move up and down.

[0027] Reference Figure 2 and Figure 3 The limiting component includes a limiting cylinder 13, the bottom end of which is fixedly connected to the upper surface of the moving plate 1. A limiting post 14 is slidably connected inside the limiting cylinder 13, and the top end of the limiting post 14 is fixedly connected to the inner top wall of the U-shaped plate 9. A limiting piece 15 is fixedly connected to the bottom end of the limiting post 14, and the outer wall of the limiting piece 15 is slidably connected to the inner wall of the limiting cylinder 13.

[0028] Specifically, during the upward movement of the U-shaped plate 9, the U-shaped plate 9 will cause the limiting post 14 to slide on the inner wall of the limiting cylinder 13, and at the same time, it will cause the limiting piece 15 to slide in the inner wall of the limiting cylinder 13, which is used to limit the lifting and lowering of the U-shaped plate 9 and improve its stability.

[0029] Reference Figure 3 and Figure 5 The lower surface of the detection carrier plate 12 is provided with a circular groove 16, and the upper surface of the U-shaped plate 9 is fixedly connected with a support column 17; the outer wall of the support column 17 is slidably connected to the inner wall of the circular groove 16.

[0030] Specifically, during the rotation of the detection carrier plate 12, the support column 17 fixedly connected to the upper surface of the U-shaped plate 9 will passively slide on the inner wall of the circular groove 16 opened on the lower surface of the detection carrier plate 12. This can improve the stability of the detection carrier plate 12 during the rotation process, avoid deviation of detection data caused by shaking or offset, and reduce the additional operations caused by the detection personnel to adjust the posture or repeatedly calibrate, thereby reducing the frequency of manual intervention and the intensity of operation.

[0031] Reference Figure 3 and Figure 5A motor 18 is fixedly connected to the inner top wall of the U-shaped plate 9. The output end of the motor 18 is rotatably connected to the inside of the U-shaped plate 9 and fixedly connected to a short column 19. The top end of the short column 19 is connected to the lower surface of the detection carrier plate 12. A drive gear 20 is fixedly connected to the outer wall of the short column 19. A driven gear 21 is meshed with the tooth end of the drive gear 20. The inner wall of the driven gear 21 is fixedly connected to the outer wall of the rotating column 11.

[0032] Specifically, motor 218 is used to provide output. When motor 218 is started, it causes short column 19 to rotate, which in turn causes drive gear 20 to drive rotating column 11 to rotate inside U-shaped plate 9 through driven gear 21, thereby allowing detection carrier plate 12 to rotate. Drive gear 20 and driven gear 21 transmit power through gear meshing. Energy loss is small during meshing, which can effectively reduce power loss. Its transmission ratio is stable and accurate.

[0033] Working principle: In use, the moving plate 1 is moved under the car to be inspected. Then, the inspection equipment can be placed above the inspection carrier plate 12. Then, the motor 3 is started. The start of the motor 3 causes the output end of the motor 3 to rotate and connect to the inside of the fixed block 2, driving the threaded rod 4 to rotate inside the fixed block 2. During the rotation of the threaded rod 4, the threaded rod 4 will drive the internal threaded slider 5 to move. The movement of the internal threaded slider 5 drives the sliding column 8 to move through the fixed block 7 and slide on the inner wall of the inclined groove 10 opened on the outer wall of the U-shaped plate 9. As the sliding column 8 slides on the inner wall of the inclined groove 10, it causes the U-shaped plate 9 to move upward. During the upward movement of the U-shaped plate 9, the U-shaped plate 9 will drive the limiting column 14 to slide inside the limiting cylinder 13, and at the same time drive the limiting piece 15 to slide on the inner wall of the limiting cylinder 13. The movement of the internal thread slider 5 causes the fixing block 7 to drive the sliding column 8 to move and slide on the inner wall of the inclined groove 10, thereby enabling the detection carrier plate 12 to rise and fall. The structure is simple, reducing the processing, manufacturing and assembly costs. The lifting process is highly stable, has low requirements for installation space, and is highly adaptable.

[0034] When it is necessary to rotate the detection carrier plate 12, the second motor 18 is started. The start of the second motor 18 causes the short column 19 to rotate, which in turn causes the drive gear 20 to rotate. The rotation of the drive gear 20 drives the rotating column 11 to rotate inside the U-shaped plate 9 through the driven gear 21. In turn, the rotating column 11 drives the detection carrier plate 12 to rotate. During the rotation of the detection carrier plate 12, the support column 17 will passively slide on the inner wall of the circular groove 16. By starting the second motor 18, the short column 19 is rotated, which in turn causes the rotating column 11 to drive the detection carrier plate 12 to rotate, thus achieving the effect of rotating the detection carrier plate 12. The rotation operation can accurately align with a specific detection position, reduce manual bending, climbing and other auxiliary actions, reduce the intensity of operation and improve detection efficiency.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
