A test spindle 304 and a sensor body are provided inside one side of the frame body 3. like Figure 1 and Figure 2 As shown, during the test, the automobile tire is installed on the test spindle 304, and the spindle is driven by the motor to rotate at high speed to simulate the movement state of the tire during driving; the sensor installed inside the support frame 301 can monitor the vibration, eccentricity and imbalance of the tire in real time; the sensor data may include the mass distribution of the tire, the dynamic balance, etc.; the collected monitoring data is transmitted to the display screen 302 through the control panel for real-time analysis; the system can calculate whether the tire is unbalanced and give specific balance adjustment suggestions; when imbalance is detected, the operator can adjust the tire according to the displayed information, such as adding balancing lead blocks to ensure that the tire can work in the best condition; accurate dynamic balance detection helps to improve the stability and safety of the vehicle and reduce the risk of bumps and accidents that may be caused during driving; by maintaining the dynamic balance of the tire, the uneven wear of the tire can be reduced, thereby extending the service life of the tire.

[0031] like Figure 1 and Figure 2 As shown, a protective assembly 4 for ensuring the safety of the tire during the test is fixedly installed on the upper surface of the bottom plate 1. The protective assembly 4 is located on one side of the test spindle 304. Specifically, the protective assembly 4 includes a bottom protective mold 401 and a top protective mold 402. The bottom protective mold 401 and the top protective mold 402 are both semi-enclosed structures. One side of the bottom protective mold 401 and one side of the top protective mold 402 are flipped and connected by a hinge 403, so that the top protective mold 402 can be flexibly flipped and locked; this structural design allows the protective assembly 4 to be easily opened and closed when the tire is placed and put away; by flipping the top protective mold 402, the top protective mold 402 and the bottom protective mold 402 can be easily flipped and locked. 401 is in an open state, and the semi-enclosed structure of the bottom protective mold 401 is exposed, which is used to place the tire in the bottom protective mold 401, and the top protective mold 402 is turned upside down on the bottom protective mold 401 by rotating the top protective mold 402 in the opposite direction, and the locking assembly 404 is arranged between the other side of the bottom protective mold 401 and the other side of the top protective mold 402 to achieve locking between the bottom protective mold 401 and the top protective mold 402. After the bottom protective mold 401 and the top protective mold 402 are locked, the locking assembly 404 can ensure that they remain in the correct position to avoid loosening due to vibration or other external forces, thereby further enhancing the protection effect.

[0032] like Figure 1 and Figure 2 As shown, during the test, the bottom protection mold 401 can support the tire, while the flipped top protection mold 402 is closed above the tire to form a closed protective space; this structure helps prevent the tire from accidentally flying out or being partially damaged during the test, thereby ensuring safety.

[0033] like Figure 1 and Figure 2 As shown, in general, the hinge 403 design and locking mechanism of the bottom protection mold 401 and the top protection mold 402 make the placement and removal of the tire very convenient and reduce the operation time; the protection component 4 can effectively prevent accidents during the tire testing process and reduce the potential threat to the operator and surrounding personnel.

[0034] like Figure 1 and Figure 2 As shown, the top protective mold 402 is provided with an LED lighting device inside, which can provide a clear light source in low-light or dark environments, making it more convenient for users to check and operate tires and reducing errors or accidents that may be caused by insufficient light.

[0036] like Figure 1 and Figure 2 As shown, the upper surface of the first reinforcement plate 40401 and the lower surface of the second reinforcement plate 40402 are both provided with a buffer pad 40405, and the material of the buffer pad 40405 is rubber; rubber has good elasticity and compression properties, can effectively absorb dynamic loads caused by impact or vibration, reduce the impact force transmitted to the connection structure, and protect the equipment from damage; and the rubber material has a high surface friction coefficient, which can increase the friction between the first reinforcement plate 40401 and the second reinforcement plate 40402, prevent the upper and lower components from sliding, and ensure a stable connection.

[0037] like Figure 3 As shown, a cylinder 405 is rotatably provided on the upper surface of the base plate 1, and an output end of the cylinder 405 is hingedly provided to the top of the top protective mold 402. Through the extension and retraction of the cylinder 405, the top protective mold 402 is automatically flipped on the bottom protective mold 401. The automatic flipping mechanism reduces the need for manual operation and improves work efficiency, especially in operation scenarios with high repetitiveness.

[0038] like Figure 4 As shown, the bottom protection mold 401 and the top protection mold 402 have the same structure, wherein the bottom protection mold 401 includes an arc-shaped bottom block 40101, a first side plate 40102 and a second side plate 40103, an arc-shaped recessed portion 40104 is formed on the upper surface of the arc-shaped bottom block 40101, the first side plate 40102 and the second side plate 40103 are respectively located at two ends of the arc-shaped bottom block 40101, and the first side plate 40102, the second side plate 40103 and the arc-shaped bottom block 40101 form the above-mentioned semi-enclosed structure, and the shape of the recessed portion 40104 of the arc-shaped bottom block 40101 matches the contour of the automobile tire, so that the tire can The first side plate 40102 and the second side plate 40103 close the two sides of the tire, forming a semi-enclosed structure with the arc-shaped bottom block 40101. This structure not only provides comprehensive support for the tire, but also effectively disperses the external force applied to the tire to protect the tire from damage. Through the semi-enclosed design, the bottom protection mold 401 can effectively withstand external shocks and pressure, reducing the risk of wear and damage to the tire during transportation or storage.

[0039] like Figure 4As shown, a number of buffer airbags 40105 are fixedly installed in the arc-shaped recessed parts 40104 of the bottom protective mold 401 and the top protective mold 402. The buffer airbags 40105 are made of rubber with a thickness of 2CM. When the automobile tires are positioned inside the bottom protective mold 401 and the top protective mold 402, the buffer airbags 40105 are arranged. The buffer airbags 40105 can effectively absorb and disperse external impact forces, avoid direct damage to the tires during transportation or storage, and ensure the integrity of the tires.

[0040] like Figure 5 As shown, a positioning assembly 5 for positioning the automobile tire is provided on the frame body 3 and on one side close to the test spindle 304. Through the positioning assembly 5, the automobile tire is positioned inside the bottom protective mold 401 and the top protective mold 402, and the central axis of the automobile tire is aligned with the central axis of the test spindle 304, so as to facilitate positioning the test spindle 304 at the center of the automobile tire, and is used to quickly position and install the automobile tire on the test spindle 304; the positioning assembly 5 provides stable support, so that the tire is not easy to slide during the positioning process; this ensures that the test result of the tire will not be affected by position deviation during the test; once the tire is positioned in place, the test spindle 304 can be quickly and conveniently aligned with the center of the tire and directly docked with the tire, thereby simplifying the installation process.

A first through hole for the test spindle 304 to pass through is provided at the center of the fixed plate 501. Four limiting slide grooves 502 are provided at equal angles inside the fixed plate 501 and around its own central axis. The limiting slide grooves 502 are linear structures, and the extension lines of the limiting slide grooves 502 pass through the center point of the fixed plate 501. A slidable slide is provided inside the limiting slide grooves 502 of the fixed plate 501. Block 503, a rotatable rotating block 504 is provided at the center of the fixed plate 501, a second through hole overlapping with the first through hole is provided at the center of the rotating block 504, a connecting rod 505 is provided between the slider 503 and the rotating block 504, one end of the connecting rod 505 is hinged to the slider 503, and the other end of the connecting rod 505 is hinged to the rotating block 504, an extension block 506 is fixedly installed on the slider 503, and an arc-shaped veneer 507 is provided on the outer surface of the extension block 506.

[0042] like Figure 5 and Figure 6As shown, the rotation of the rotating block 504 causes the connecting rod 505 to move in conjunction, and drives the four sliders 503 to slide synchronously inside the limiting slide groove 502 and around the central axis of the first through hole, so that the arc-shaped surface 507 on the extension block 506 fits on the inner ring of the automobile tire, so that the central axis of the automobile tire coincides with the central axis of the test spindle 304 in the first through hole; this structure can achieve high-precision alignment and ensure the accuracy of the test results, which is crucial to the evaluation of automobile performance; multiple sliders 503 can be synchronously adjusted by simply rotating the rotating block 504, which is easy to operate and reduces the complexity of manual adjustment.

[0043] like Figure 5 and Figure 6 As shown, specifically, a plurality of semi-cylindrical rubber strips 508 are provided on the arc-shaped surface 507 of the expansion block 506.

[0045] Working principle: When in use, the top protective mold 402 is automatically flipped on the bottom protective mold 401 with the help of the extension and contraction of the cylinder 405. By flipping the top protective mold 402, the top protective mold 402 and the bottom protective mold 401 are in an open state, and the semi-enclosed structure of the bottom protective mold 401 is exposed.

[0046] Then, with the help of a forklift outside the device, the automobile tire is moved to the inside of the bottom protection mold 401, and the inner ring of the automobile tire is positioned on the outside of the positioning component 5. By driving the motor 509, the rotating block 504 is rotated, and the connecting rod 505 is linked to it, and the four sliders 503 are driven to slide synchronously inside the limiting slide groove 502 and around the central axis of the first through hole, so that the arc-shaped surface 507 on the expansion block 506 is attached to the inner ring of the automobile tire. At this time, the central axis of the automobile tire coincides with the central axis of the test spindle 304 in the first through hole, and the automobile tire is fixed on the test spindle 304.

[0047] Then, the positioning assembly 5 is driven in reverse to make the expansion block 506 detach from the inner ring connection of the automobile tire, and the main shaft is driven by the motor to rotate at high speed to simulate the movement state of the tire during driving; the sensor installed inside the support frame 301 can monitor the vibration, eccentricity and imbalance of the tire in real time.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
