[0075] Working principle: The tire clamping mechanism 4 drives the spur gear three 31 to rotate through the drive motor 32, and then drives the gear disk one 30 and the rotating shaft two 29 to rotate. The rotating shaft two 29 drives the rotating frame one 33 and the cylinder one 34 to rotate synchronously, thereby realizing the rotation of the tire to be tested and simulating the normal driving process. The support mechanism 37 drives the bevel gear one 36 to rotate through the motor two 35. The bevel gear one 36 drives the bevel gear two 40 and the lead screw two 39 to rotate, so that the sleeve one 41 and the arc-shaped support plate 43 slide and expand away from the center on the cylinder one 34, thereby adjusting the support position and angle of the tire to adapt to and support different sizes of tires to be tested. The detection environment simulation mechanism 5 adjusts the position and angle of the rotating roller 51 through the sliding support seat 45 and the angle adjustment mechanism 46 to simulate different road surface environments and inclination angles. The road surface coatings 52 with different roughnesses and the pressure sensors 53 on the rotating roller 51 can simulate different road surface conditions and tire force conditions. When the inclination angle needs to be changed, the controller 6 controls the electric telescopic rod one 47 to push the strip-shaped frame 50 and the L-shaped bearing plate 48 to rotate to the target inclination angle. When it is necessary to detect road surfaces with different roughnesses, the sliding support seat 45 runs and slides back and forth along the linear track 44 to ensure that the road surface with the target roughness is directly below the tire to be tested.

[0076] Beneficial effects: The designs of the tire clamping mechanism 4 and the detection environment simulation mechanism 5 enable the device to comprehensively simulate various working conditions of the tire in actual use, including different road surface conditions, inclination angles, and force conditions. This helps to improve the accuracy and reliability of tire durability evaluation.

[0081] The working principle and the beneficial effects of the above technical solution are as follows:

[0082] Workflow:

[0083] Tire cleaning and pretreatment: Before and after the formal test, start the cleaning and washing mechanism 54 to clean the tire to be tested. By adjusting the parameters of the electric telescopic rod II 68, the electric lifting rod II 69, and the cleaning motor 76, ensure that the dirt and impurities on the tire surface are completely removed. At the same time, use the camera 79 to record the tire image information before and after cleaning.

[0084] Test preparation and parameter setting: Carry out preparation work such as tire clamping, support adjustment, and road condition simulation according to the steps in Embodiment 4, and set the required test parameters.

[0085] Test execution and data collection: During the test execution, continuously collect data such as the force distribution and wear condition of the tire, and use the controller 6 for real-time monitoring and analysis. At the same time, pay attention to observing the tire image information recorded by the camera 79 to promptly discover and record any abnormal wear or damage conditions.

[0086] Test end and report generation: After the test ends, the controller 6 processes and analyzes the collected data to generate a comprehensive report including tire durability evaluation, abnormal wear analysis, etc. At the same time, evaluate the cleaning effect of the tire based on the image information recorded by the camera 79 and give improvement suggestions.

[0087] Working principle: The cleaning and washing mechanism 54 drives the pulley II 65 to rotate through the motor III 66, and then drives the pulley I 62 and the vertical pipe I 61 to rotate, so that the spray pipe 64 can evenly spray the cleaning liquid onto the tire to be tested. The electric telescopic rod II 68 and the electric lifting rod II 69 are used to adjust the position and height of the strip hole plate 74 and the disk brush I 77 to adapt to tires of different sizes. The cleaning motor 76 drives the disk brush I 77 to rotate. At the same time, the motor IV 71 drives the rotating rocker 83 to rotate, and the rotating rocker 83 drives the connecting rod I 84 and the vertical rod I 70 to slide up and down reciprocally. The vertical rod I 70 drives the strip hole plate 74 and the disk brush to swing up and down for cleaning the tire. The electric rotating seat 80 is used to drive the tire to be tested to rotate to complete the cleaning and washing of the entire surface. The sewage tank 82 is used to collect the sewage and impurities generated during the cleaning process. The camera 79 is used to record the image information of the tire before and after cleaning and washing, so as to analyze the wear condition of the tire later. The electric rotating seat 80 is used to place and rotate the tire to be tested, which is convenient for comprehensive cleaning and detection.

[0088] Beneficial effects: The introduction of the cleaning and washing mechanism 54 enables the device to clean the tire before detection, removing dirt and impurities on the tire surface and improving the accuracy and reliability of detection. At the same time, the design of the camera 79 and the electric rotating seat 80 enables the device to record the image information of the tire and perform comprehensive cleaning and detection on it, providing more comprehensive data support for the durability evaluation of the tire.
