[0025] Example

[0026] Please see Figures 1-4 A tire puncture resistance testing device includes a base plate 1, four sets of support columns 2 and a top plate 3. The four sets of support columns 2 are connected to the top of the base plate 1, and the top plate 3 is connected to the top of the four sets of support columns 2. It also includes a multi-row puncture mechanism, a position adjustment mechanism, a moving mechanism, a lifting mechanism, a lifting plate 23 and an installation mechanism.

[0027] The position adjustment mechanism is installed at the bottom of the top plate 3, the moving mechanism is installed at the bottom of the position adjustment mechanism, the lifting mechanism is installed at the bottom of the moving mechanism, and the lifting plate 23 is connected to the bottom of the lifting mechanism.

[0028] The multi-row puncture mechanism is arranged and installed on the top of the base plate 1. The multi-row puncture mechanism is used to test tires of different specifications and types. Each multi-row puncture mechanism includes a fixed plate 4 and multiple sets of puncture needles 5. The fixed plate 4 is connected to the top of the base plate 1, and the multiple sets of puncture needles 5 are arranged and connected to the top of the fixed plate 4.

[0029] The mounting mechanism includes two sets of first mounting plates 6, two sets of cylinders 7, and two sets of connecting plates 8. The two sets of first mounting plates 6 are symmetrically mounted on the bottom end of the lifting plate 23. The two sets of cylinders 7 are symmetrically connected to the two sets of first mounting plates 6 respectively. The two sets of connecting plates 8 are rotatably connected to the output ends of the two sets of cylinders 7 respectively. Each set of connecting plates 8 is provided with multiple sets of mounting holes 9 for corresponding installation with bolt holes on the tire hub. The tire is fixed to the two sets of connecting plates 8 by bolts. The multi-row puncture mechanism can test tires of different specifications and types, effectively solving the problem that existing devices cannot easily replace tires of different specifications and types for testing and have poor versatility. The position adjustment mechanism, moving mechanism, and lifting mechanism work together to accurately adjust the puncture position and height, which not only simplifies the process but also... The new device streamlines the testing process, making operation more convenient and improving testing efficiency. It overcomes the shortcomings of some existing testing devices, such as complex structure, inconvenient operation, and low testing efficiency. The installation mechanism, through the design of two sets of cylinders 7, connecting plates 8, and mounting holes 9 corresponding to the tire and wheel hub bolt holes, can firmly fix the tire. Furthermore, the bolt connection can simulate the pressure and stress conditions experienced by the tire during actual driving, making the test results closer to actual working conditions. Compared with the poor accuracy and reliability of existing devices, this device can provide more accurate and reliable test data. It is of great significance for puncture resistance testing in the tire research and development and production process, helping to ensure that tires have good puncture resistance performance in actual use and improve vehicle driving safety.

[0030] Please see Figures 1-4The position adjustment mechanism includes a mounting frame 10, an electric cylinder 11, two sets of slide rails 12, and a mounting slot 13. The mounting frame 10 is fixedly installed on one side of the top plate 3. The electric cylinder 11 is connected to the mounting frame 10, and the output end of the electric cylinder 11 is connected to one side of the mounting slot 13. Both sets of slide rails 12 are connected to the bottom of the top plate 3, and the mounting slot 13 is slidably connected to the two sets of slide rails 12. This design further optimizes the precise adjustment performance of the testing device. The electric cylinder 11, in cooperation with the mounting frame 10, can provide a stable and precise driving force for the movement of the mounting slot 13, which greatly improves the efficiency and accuracy of adjustment compared to manual adjustment. The sliding connection between the two sets of slide rails 12 and the mounting slot 13 effectively limits the direction of movement of the mounting slot 13, avoids deviation, and makes the movement process smoother, ensuring the accuracy of subsequent puncture position adjustment. This solves the problem of insufficient precision and cumbersome operation in the puncture position adjustment of some existing testing devices, further simplifying the testing process and improving testing efficiency.

[0031] Please see Figures 1-4 The moving mechanism includes a motor 14, a lead screw 15, two sets of sliders 16, and a moving block 17. The motor 14 is connected to one side of the mounting groove 13, and the output end of the motor 14 is connected to the lead screw 15. The lead screw 15 is rotatably connected to the mounting groove 13. Two sets of sliding grooves are provided in the mounting groove 13, and the two sets of sliders 16 are slidably connected to the two sets of sliding grooves respectively. The two sets of sliders 16 are connected to the moving block 17, and the moving block 17 is connected to the lead screw 15. By driving the lead screw 15 to rotate through the motor 14, and cooperating with the connection between the two sets of sliders 16 and the moving block 17, precise horizontal movement control of the test component is achieved. The use of the motor 14 replaces the traditional manual operation, enabling more stable and faster adjustment of the test position and significantly improving test efficiency. The cooperation between the lead screw 15 and the moving block 17 can accurately convert the rotational motion of the motor 14 into linear motion, achieving high-precision position adjustment. It can accurately test different parts of the tire, effectively overcoming the problems of insufficient accuracy and inconvenient operation in the existing device when adjusting the test position, and further improving the accuracy and reliability of the test.

[0032] Please see Figures 1-4The lifting mechanism includes a hydraulic cylinder 18, two sets of guide rods 19, and a second mounting plate 20. The second mounting plate 20 is connected to the bottom end of the moving block 17, the top end of the hydraulic cylinder 18 is connected to the bottom end of the second mounting plate 20, the output end of the hydraulic cylinder 18 is connected to the top end of the lifting plate 23, the bottom ends of the two sets of guide rods 19 are connected to the top end of the lifting plate 23, and the two sets of guide rods 19 are slidably connected to the second mounting plate 20. The hydraulic cylinder 18 provides strong and stable power for the lifting of the lifting plate 23, and can quickly adjust the distance between the tire and the puncture needle 5 to adapt to different testing requirements and improve testing efficiency. The slidable connection between the two sets of guide rods 19 and the second mounting plate 20 plays a good guiding and stabilizing role in the lifting process of the lifting plate 23, preventing shaking or deviation during the lifting process, ensuring the stability and accuracy of the testing process, solving the problem of instability and affecting the accuracy of test results in some existing testing devices during lifting adjustment, and further improving the overall performance of the testing device.

[0033] Please see Figures 1-4 The system also includes a pressure sensor 21 and a data analysis module 22. A groove is provided at the top of the fixing plate 4, and the pressure sensor 21 is installed in the groove. The bottom end of the puncture needle 5 is connected to the pressure sensor 21. The data analysis module 22 is installed on one side of the base plate 1 and is electrically connected to the pressure sensor 21. The setup of the pressure sensor 21 and the data analysis module 22 provides strong support for the acquisition and analysis of test data. The pressure sensor 21, installed in the groove at the top of the fixing plate 4 and connected to the puncture needle 5, can collect the pressure data experienced by the tire during puncture in real time and accurately. The data analysis module 22, electrically connected to the pressure sensor 21, can perform rapid and accurate analysis and processing of the collected data. Compared with existing devices that rely on manual judgment of test results, this design greatly improves the accuracy and reliability of test results, providing more scientific and accurate data for tire research and development and production, and helping to further optimize the design and production process of tire puncture resistance.

[0034] In summary, this tire puncture resistance testing device, with its multi-row puncture mechanism, can test tires of different specifications and types, effectively solving the problems of existing devices that cannot easily change to different tire specifications and types for testing and lack versatility. The position adjustment mechanism, moving mechanism, and lifting mechanism work together to precisely adjust the puncture position and height, which not only simplifies the testing process and makes operation more convenient, but also improves testing efficiency, overcoming the shortcomings of some existing testing devices that are complex in structure, inconvenient to operate, and have low testing efficiency. The installation mechanism, through the design of two sets of cylinders 7, connecting plates 8, and mounting holes 9 corresponding to the tire and wheel hub bolt holes, can firmly fix the tire. Moreover, the bolt connection can simulate the pressure and stress conditions that the tire experiences during actual driving, making the test results closer to actual working conditions. Compared with the poor accuracy and reliability of existing devices, this device can provide more accurate and reliable test data, which is of great significance for puncture resistance testing in the tire research and development and production process, helping to ensure that tires have good puncture resistance performance in actual use and improve vehicle driving safety.
