Description

Technical Field

[0001] The present invention relates to the technical field of tire detection, and particularly to a tire anti-slip performance detection device for new energy vehicles. Background Art

[0002] With the continuous enhancement of people's environmental awareness and the continuous reduction of fossil energy, new energy vehicles have also developed rapidly. Compared with traditional vehicles, new energy vehicles are more environmentally friendly and energy-saving. However, with the gradual popularization of new energy vehicles, people pay more and more attention to the driving safety of new energy vehicles. Tires are one of the indispensable components of new energy vehicles, and the anti-slip performance of tires largely determines the driving safety of vehicles. Tires with poor anti-slip performance increase the braking distance during vehicle driving and are more prone to skidding, which can cause serious safety accidents. Therefore, during the production and manufacturing of new energy vehicles, a detection device is needed to detect the anti-slip performance of tires.

[0003] Since vehicles will experience different driving environments during actual use, tires will come into contact with roads under different conditions. However, most of the existing tire anti-slip performance detection devices have a single function and are inconvenient for multi-environment detection of tires, thus affecting the accuracy and reliability of the tire anti-slip performance detection results and having certain defects in use; in the prior art, most of the tire anti-slip tests adopt the tire side support mode or the simulated detection road surface inclination support mode, which cannot truly simulate the anti-slip performance of new energy vehicle tires on the ground in the forward direction, and the detection error is greatly increased because dirt will adhere to the tire surface during detection by multiple modes. Therefore, corresponding technical solutions need to be designed to solve this problem. Summary of the Invention

The electric push rod device 52 is used to telescopically adjust the positions of the push rod 521 and the bracket 53. The bracket 53 is used to support and fix the cleaning structure 54. Multiple groups of brush rods 541 in a circular track are used to contact the bottom of the tire body 473 to clean dust and impurities, remove the attachments during the detection of the tire body 473, reduce the detection error, and improve the accuracy of the anti-slip performance detection. Multiple groups of support rods 5441 are used to stably support the blower 544. The blower 544 is used for air extraction and exhaust. The dust removal groove 542 is used to store dust and impurities. Both the filter element 543 and the filter screen 545 are used to filter and purify dust and impurities.

[0061] The number of anti-slip test seats 21 is several, and rainwater ground, ice and snow ground, cement ground, asphalt ground, potholed soil ground, stone slab ground, gravel ground, and rubber ground can be simulated above them;

[0062] Characteristics of rainwater ground: The road surface is slippery, which is likely to cause the reduction of the friction between the tire and the ground, and evaluate the braking performance, handling stability, and traction of the tire on the slippery road surface;

[0063] Characteristics of ice and snow ground: The road surface is covered with ice and snow, the friction is extremely low, and the driving risk is high. Test the anti-slip performance of the tire on the ice and snow ground, including braking distance, side-slip risk, and tire grip;

[0064] Characteristics of cement pavement: The pavement has high hardness, but may have cracks or unevenness due to construction or aging. Evaluate the wear resistance, grip of the tire on the cement pavement, and the handling stability at different speeds;

[0065] Characteristics of asphalt pavement: The pavement has good flexibility, but is easily affected by temperature and humidity. Test the anti-slip performance of the tire on the asphalt pavement, especially its performance under high temperature or humid conditions;

[0066] Characteristics of potholed dirt road: The pavement is uneven, with a large number of potholes and dirt. Evaluate the passability, grip of the tire on the complex terrain, and the adaptability of the suspension system;

[0067] Characteristics of stone slab pavement: The pavement is paved with stone slabs, and there may be unevenness and gaps. Evaluate the braking performance and handling stability of the tire on the stone slab pavement;

[0068] Characteristics of sand and gravel pavement: The pavement is composed of sand and gravel, with relatively large friction but easy to raise dust. Evaluate the traction, braking performance and anti-dust ability of the tire on the sand and gravel pavement;

[0069] Characteristics of rubber pavement: The pavement is made of rubber particles or rubber sheets, usually used in sports fields or parking lots. Test the grip and wear resistance of the tire on the rubber pavement.

[0070] Working principle: Set different types of road surfaces above the anti-slip test seat 21, and then install the tire body 473 at the middle of the installation shaft rod 474;

[0071] First, start the drive motor one 43 of the tire control mechanism 4 to automatically control the drive shaft one 433 to drive the gear disk one 431 and the gear disk two 432 to rotate, engage the gear disk three 441 and the gear disk four 442 to control the installation shaft frame 44 to rotate, so that the shaft disk one 444 drives the shaft disk two 452 to transmit, thereby enabling the support column 45 to rotate stably, driving the lower drive bevel gear 4721 to engage the fixed bevel gear 4751 to control the rotation, driving the fixed shaft rod 475 and the pinion 4752 to rotate stably, and the pinion 4752 drives the large gear 4741 through the transmission belt to control the installation shaft rod 474 to rotate stably, thereby driving the tire body 473 to rotate;

[0072] Start the electric hydraulic device 31 of the lifting and adjusting mechanism 3 to automatically control the telescopic adjustment of the hydraulic column 311, thereby driving the tire control mechanism 4 to adjust the height downward, so that the tire body 473 contacts downward above the anti-slip test seat 21 for detection;

[0073] And the drive motor two 46 can be started to automatically control the drive shaft two 461 and the drive gear disk 462 to rotate, engage the fixed gear disk 472 to drive the fixed frame 471 to rotate, so that the tire body 473 rotates and adjusts at different angles for simulation detection;

[0074] Start the motor 227 of the test mode switching drive structure 22 to automatically control the rotation of the drive shaft rod 228 and the fourth shaft disc 229. The fourth shaft disc 229 and the third shaft disc 225 are driven by a transmission belt, causing the rotating column 222 and the rotating gear disc 221 to rotate. The rotating gear disc 221 passes through the through port 111 and meshes with the toothed plate 201, causing the moving plate 2 to move horizontally. The moving plate 2 is located inside the fixed seat 11 and stably moves horizontally to adjust the position, thereby switching different anti-slip test seats 21;

[0075] After each anti-slip test seat 21 is detected, it is necessary to start the electric push rod device 52 of the tire cleaning mechanism 5 to automatically control the telescopic adjustment of the push rod 521 and the bracket 53, so that the cleaning structure 54 is located below the tire body 473. When the tire body 473 rotates and revolves, it is cleaned by multiple brush rods 541 to remove dust and impurities. At the same time, the blower 544 is started to collect dust and impurities through the dust removal tank 542 and filter and purify them through the filter element 543;

[0076] After the tire cleaning mechanism 5 finishes cleaning, switch the detection modes of different anti-slip test seats 21 to effectively detect the anti-slip performance of new energy vehicle tires, improving the test efficiency and accuracy.

The components are all common standard parts or parts known to those skilled in the art. Their structures and principles can all be learned by those skilled in the art through technical manuals or obtained through conventional experimental methods. The problem solved by the present invention is that it is inconvenient to perform multi-environmental detection on tires. Using the tire side support mode or the simulated detection road surface inclination support mode, the anti-slip performance of new energy vehicle tires facing the ground cannot be truly simulated. And when detecting through multiple modes, dirt will adhere to the tire surface, greatly increasing the detection error. Through the mutual combination of the above components of the present invention, through the design of the tire drive mechanism and the tire angle adjustment mechanism 47 in the tire control mechanism 4, precise driving and angle adjustment of the tire can be achieved, ensuring the stable rotation of the new energy vehicle tire during the test process, and realizing the rapid adjustment of the tire angle, meeting the requirements of different test scenarios, and improving the comprehensiveness and accuracy of the test; through the lifting and adjusting mechanism 3 connected to both ends of the lower part of the tire control mechanism 4, it is convenient to automatically control and adjust the height of the tire control mechanism 4, so that it supports above the anti-slip test seat 21 for anti-slip testing; through the test mode switching drive structure 22 connected to the rear end of the moving plate 2, the rapid movement of the moving plate 2 and multiple groups of anti-slip test seats 21 above it is realized, thus facilitating the switching of different test modes, improving the test efficiency, and reducing the operation difficulty; through the tire cleaning mechanism 5 arranged on the side of the tire control mechanism 4, it is convenient to approach the tire and effectively remove dirt and impurities on its surface, ensuring the accuracy and reliability of the test results.
