[0002] Car is a common means of transportation in modern times, mainly used for travel and transportation. According to the "Terms and Definitions of Automobile and Trailer Types", the definition of automobile is as follows: a power-driven, non-track-borne vehicle with 4 or more wheels, mainly used for: carrying people and (or) goods; towing vehicles carrying people and (or) goods; special purposes. As the car is constantly driving, its tires are constantly wearing out. Excessively worn tires have insufficient grip and are prone to blowouts, causing traffic accidents. Therefore, the wear resistance of the tires needs to be tested after production.

[0003] For example, the Chinese patent (CN202020624654.2) discloses a new energy vehicle tire wear resistance detection device, which belongs to the field of tire wear resistance detection, including a base, threaded barrels and brackets are arranged on both sides of the top of the base, a screw rod passes through the inside of the threaded barrel, and a resistance plate is arranged at the bottom of the screw rod. A second electric push rod is arranged on the top of the base. Before work, the road surface simulation coating is adjusted to the lowest point by the second electric push rod, and then the tire is installed, and then the second electric push rod is started. The second electric push rod pushes the bearing seat to rise, so that the road surface simulation coating rises and contacts the tire. In this way, the device can be suitable for testing tires of more sizes, thereby improving the scope of application of the device.

[0004] However, the above scheme is to fix the tire by clamping on both sides. In order to ensure that the tire does not eccentrically shake when it rotates, high precision is required when installing the tire, which requires more time to adjust, resulting in reduced detection efficiency. In view of the above problems, a vehicle tire wear resistance detection device is proposed to solve the problem. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0019] Refer to Figure 1-2As shown in the figure, an automobile tire abrasion resistance detection device includes a base 1. A workbench 2 is fixedly connected to the rear side of the upper surface of the base 1. The fixed connection between the base 1 and the workbench 2 ensures the stability of the device, providing a solid foundation for subsequent tire abrasion resistance detection. An inner support assembly 5 is arranged at the upper front side of the workbench 2. Four electric push rods 6 are fixedly installed on the upper surface of the base 1 and the front side of the workbench 2. The output ends of the four electric push rods 6 are fixedly connected to a mounting plate 7. Two bearing seats 8 are fixedly connected to the left and right sides of the upper surface of the mounting plate 7. A friction roller 9 is rotatably connected between the two bearing seats 8. The front end of the left friction roller 9 passes through the front bearing seat 8 and is fixedly connected to a driven wheel 10. A servo motor 11 is fixedly installed at the left bottom of the mounting plate 7. The output end of the servo motor 11 is fixedly connected to a driving wheel 12. The driving wheel 12 is in transmission connection with the driven wheel 10 through a belt or a chain. The friction roller 9 is driven by the servo motor 11 and the transmission system (belt or chain), and can achieve a stable rotation speed and direction, providing a constant friction condition for the tire, so as to accurately evaluate the abrasion resistance of the tire.

[0020] The inner support assembly 5 includes a mounting disc 501, and the mounting disc 501 is fixedly connected to the front side of the workbench 2. A fixed disc 502 is rotatably connected to the front side of the mounting disc 501. A fixed rod 503 is fixedly connected to the middle of the front side of the fixed disc 502.

[0021] Specifically, a threaded rod 504 is arranged inside the fixed rod 503. The rear end of the threaded rod 504 is rotatably connected to the front end of the fixed disc 502. The front end of the threaded rod 504 passes through the front side of the fixed rod 503 and is fixedly connected to a hand wheel 505. The rear side of the hand wheel 505 is rotatably connected to the front end of the fixed rod 503. The designs of the threaded rod 504 and the hand wheel 505 make the process of tightening and loosening the inner support plate 516 simple and convenient, and the operator can intuitively control the tightening force.

[0022] A first fixing ring 506 is fixedly connected to the rear side of the outer surface of the fixed rod 503. At least three first connecting rods 507 are rotatably connected to the outside of the first fixing ring 506. The ends of the first connecting rods 507 are rotatably connected to a first connecting ear 508. A second fixing ring 509 is fixedly connected to the middle of the outer surface of the fixed rod 503. At least three second connecting rods 510 are rotatably connected to the outside of the second fixing ring 509. The ends of the second connecting rods 510 are rotatably connected to a second connecting ear 511.

[0023] A moving ring 512 is slidably connected to the front side of the surface of the fixed rod 503. A threaded seat 513 is fixedly connected to the inner side of the moving ring 512. The threaded seat 513 passes through the side wall of the fixed rod 503 and is threadedly connected to the outer surface of the threaded rod 504. At least three third connecting rods 514 are rotatably connected to the outer side of the moving ring 512. The ends of the third connecting rods 514 are rotatably connected to third connecting ears 515. The structural design of the connecting rods and the connecting ears ensures the uniform force of the inner support plate 516 during the tightening process, avoiding damage to the tire caused by excessive local pressure.

[0024] The inner support assembly 5 further includes an inner support plate 516. The inner support plate 516 can be adaptively adjusted according to the specifications and shapes of the tires, and is applicable to the detection of a variety of tires. One side of the inner support plate 516 close to the fixed rod 503 is fixedly connected to the first connecting ear 508, the second connecting ear 511 and the third connecting ear 515. Figure 2 The figure shown is a schematic diagram after tightening. It can be understood that when the moving ring 512 is located on the side close to the handwheel 505, it is in a loosened state.

[0025] Preferably, universal moving wheels 4 are fixedly installed at the four corner positions of the bottom of the base 1. The staff can push the device to move through the universal moving wheels 4, which is convenient for transferring between different detection sites, improving the flexibility and adaptability of the device. A controller 3 is fixedly installed in the middle of the left side of the workbench 2. The controller 3 can integrally control key components such as the electric push rod 6 and the servo motor 11 to realize the automation and intelligence of the detection process.

[0026] Working principle: When in use, first place the tire above the front side of the two friction rollers 9. Then, control the electric push rod 6 through the controller 3 to push the mounting plate 7 upward to a general position, and then push the tire backward to place the inner support assembly 5 in the middle of the tire. Then, drive the threaded rod 504 to rotate through the handwheel 505. The threaded connection between the threaded seat 513 and the threaded rod 504 causes the moving ring 512 to move backward. When the moving ring 512 moves backward, the third connecting rods 514 will open under the restriction of the first fixed ring 506, the first connecting rod 507, the second fixed ring 509 and the second connecting rod 510. While the third connecting rods 514 are opening, the inner support plate 516 will tighten the tire. After tightening, then control the electric push rod 6 to make fine adjustments through the controller 3, so that the friction rollers 9 can fit on the outer surface of the tire. After that, the servo motor 11 drives the driving wheel 12 to drive the driven wheel 10 to rotate through a belt or a chain, so that the friction rollers 9 drive the tire to rotate, and then the abrasion resistance of the tire can be obtained by observing the wear degree of the tire.
