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] Please see Figure 1-4 This utility model provides a technical solution:

[0026] Example 1

[0027] Regarding the problem 1 mentioned above: Once the steering wheel is fixed, its position cannot be adjusted. When testing different positions of the steering wheel, the operator needs to move and fix the steering wheel multiple times, which makes the testing operation very cumbersome.

[0028] The solution is as follows: A testing device for automobile steering wheels includes a testing cabinet 1, a steering wheel 6, a pressure testing component 5, and a wear resistance testing component 4. The testing cabinet 1 has two guide struts 9 near the top. A connecting rod 8 is slidably connected to the guide struts 9. A movable top plate 7 is provided between the top ends of the connecting rods 8. An installation chamber 16 is provided in the middle of the movable top plate 7. Rotating columns 18 are rotatably connected to the middle of both ends of the installation chamber 16. Rotating wheels 19 are fixed on the rotating columns 18. A transmission belt 20 is provided between the rotating wheels 19. A drive motor 17 is installed on one end of the rotating column 18. A fixing block 14 is connected to the top of the movable top plate 7 through two slide rails 15. A connecting column 21 is provided between the bottom middle of the fixing block 14 and the transmission belt 20.

[0029] Furthermore, a cabinet door 22 is installed and connected on one side of the test cabinet 1, a control module 2 is set inside the bottom of the test cabinet 1, a control panel 25 is integrated on the outside of the test cabinet 1, and the steering wheel 6 is fixed to the fixing slot 12 by fixing clamps 13.

[0030] Furthermore, the pressure testing assembly 5 includes a pressure drive box, a synchronous base plate, and several pressure plates, while the wear resistance testing assembly 4 includes a lifting drive box, a mounting base plate, a rotating assembly, and several friction plates. The pressure testing assembly 5 and the wear resistance testing assembly 4 are respectively installed on the fixed top frame 24 at different positions.

[0031] Furthermore, the movable top plate 7 is located on the top of the test cabinet 1. The movable top plate 7 has a recessed structure at the top of the installation compartment 16. One end of the top of the transmission belt 20 is located outside the movable top plate 7. The slide rails 15 are symmetrically distributed on the top of the movable top plate 7. Specifically, the slide rails 15 can drive the fixing block 14 to move on the movable top plate 7, which facilitates changing the position of the steering wheel 6. At the same time, when fixing and disassembling the steering wheel 6, the fixing block 14 can be moved to the edge of the movable top plate 7, which makes it convenient for operators to install and remove the steering wheel 6 and facilitates its use.

[0032] Furthermore, the slide rail component 15 includes a slide rail and a slider. The slide rail is embedded in the top of the movable top plate 7, and the slider is slidably connected to the slide rail and fixed to the top of the fixed block 14. The fixed top frame 24 includes several support columns and support plates.

[0033] Example 2

[0034] Regarding the second problem mentioned above: the steering wheel testing equipment has a single function and cannot be moved quickly after pressure testing or other tests, requiring multiple manual disassembly and fixation before it can be tested on other test pieces.

[0035] The solution is as follows: Two fixed top brackets 24 are symmetrically installed on the top of the test cabinet 1. A synchronization plate 11 is set between the bottom of the guide support rods 9. A drive box 3 is set on the inner wall of the test cabinet 1. An adjusting screw 10 is set between the drive end of the drive box 3 and the synchronization plate 11. Specifically, through the threaded connection of the drive box 3 and the adjusting screw 10, and the directional limiting effect of the guide support rods 9 and the connecting rods 8, the lateral movement of the movable top plate 7 can be driven (see attached). Figure 1 Taking the direction in the middle as an example, the steering wheel 6 can then move to the bottom of the pressure test component 5 and the wear resistance test component 4 for testing. Several strip-shaped through holes 23 are evenly provided on the top of the test cabinet 1. Specifically, the strip-shaped through holes 23 are used for connecting and installing the connecting rod 8, as well as for subsequent lateral movement. At the same time, the strip-shaped through holes 23 near the edge of the test cabinet 1 can facilitate the use of the cable for the drive motor 17, and facilitate the normal movement of the top plate 7. A fixing groove 12 is provided in the middle of the top of the fixing block 14.

[0036] Furthermore, the synchronous plate 11 has a threaded hole in the middle and is threadedly connected to the adjusting screw 10. One end of the adjusting screw 10 is fixedly connected to the drive end of the drive box 3, and the other end is rotatably connected to the inner wall of the test cabinet 1. The structure of the fixing groove 12 is the same as the structure of the center part of the steering wheel 6. Specifically, when the steering wheel 6 is fixed, its middle part is placed into the fixing groove 12. In order to ensure the stability of the placement, the fixing groove 12 with the same structure as the steering wheel 6 is used, and the fixing clamp 13 is used for fixation.

[0037] Working principle: During operation, the steering wheel 6 is first placed on the fixed slot 12 and fixed with the fixing clamp 13. Then, the drive box 3 drives the adjusting screw 10 to rotate. With the threaded connection with the synchronous plate 11 and the limiting effect of the guide support rod 9, the moving top plate 7 is moved. At the same time, the drive motor 17 drives the rotating column 18 to rotate, which in turn drives the transmission belt 20 to rotate. With the connecting column 21, the fixing block 14 is moved, changing the position of the steering wheel 6 so that it can contact the pressure plates at various positions for comprehensive pressure testing. After the pressure test is completed, the drive box 3 and the adjusting screw 10 drive the moving top plate 7 to move laterally, moving the steering wheel 6 to the bottom of the wear resistance test assembly 4 for wear resistance testing. This eliminates the need for manual disassembly and fixing of the steering wheel multiple times, simplifying the testing process and improving testing efficiency.

[0038] This utility model comprises a test cabinet (1), a control module (2), a drive box (3), a wear resistance testing component (4), a pressure testing component (5), a steering wheel (6), a movable top plate (7), a connecting rod (8), a guide support rod (9), an adjusting screw (10), a synchronization plate (11), a fixing groove (12), a fixing clamp (13), a fixing block (14), a slide rail (15), a mounting compartment (16), a drive motor (17), a rotating column (18), a rotating wheel (19), a transmission belt (20), a connecting column (21), a cabinet door (22), a strip-shaped through hole (23), a fixed top frame (24), and a control panel (25). All components are general standard parts or parts known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this utility model is the testing of steering wheels. The existing equipment has a limited testing function, and the steering wheel cannot be adjusted after it is fixed. When testing different positions of the steering wheel, the operator needs to move and fix the steering wheel multiple times, making the testing operation very cumbersome. This invention, through the combination of the above-mentioned components, enables convenient adjustment of the steering wheel position. The transmission belt drives the fixed block to move on the moving top plate. Furthermore, the adjusting screw and drive box drive the fixed top plate to move as a whole, thereby realizing the adjustment of various positions of the steering wheel. This ensures that the steering wheel fully contacts the pressure plates on the pressure testing components, guaranteeing the test effect. At the same time, after a single test item is completed, the steering wheel can be moved directly to another testing device without disassembling it for subsequent tests.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
