Technical Field
[0001] The utility model belongs to the technical field of automobile tires, and specifically relates to a new energy automobile tire. Background Art
[0002] At present, the development trend of the automobile industry is that new energy vehicles are gradually replacing traditional fuel vehicles. With the continuous development of the new energy public transportation industry, the requirements for tires suitable for new energy vehicles are getting higher and higher. The existing ordinary performance tires can no longer meet the energy saving, wear resistance, quietness, safety and other performance indicators pursued by new energy vehicles. Tires are one of the important parts of automobiles. They are in direct contact with the road surface and work together with the automobile suspension to alleviate the impact of the car when driving. With the continuous advancement of technology, the role of tires in automobiles has been increasingly valued by people.
[0003] At present, most automobile tires are in the state of a single-cavity structure of ordinary tires. When the vehicle is driving, there are often sharp objects such as thumbtacks, broken iron filings, broken glass slag, and gravel on the road, which bring safety hazards to the vehicle during driving. Especially when the vehicle is driving on the highway, if the tire is pierced by a sharp object, the tire will instantly release pressure or even burst, thus causing the vehicle to tilt, making it difficult for the driver to control the vehicle, and traffic accidents will occur, with disastrous consequences. In particular, there is always a major safety hazard of punctures and blowouts in small cars when driving at high speeds. Because the tires of new energy vehicles are prone to accelerated wear and tire aging, they are more prone to punctures and blowouts. A blowout is a very serious safety accident, especially a blowout on a highway, which can cause the vehicle to lose control, roll over, and cause traffic accidents. Most new energy vehicles now use vacuum tires. After a puncture, the tire leaks air slowly, which can ensure that the car can continue to travel for a certain distance. However, after a vacuum tire blows out, the air in the tire will still leak out quickly, causing the tire to soften and deflate quickly, causing the car wheel rim to contact the road surface, resulting in loss of control of the vehicle at high speeds, causing danger and traffic accidents. Since new energy vehicles do not have the roar of the engine, the noise inside the car is greatly reduced, so the sensitivity of people in the car to noise will increase. Once a puncture or blowout occurs, the sound inside the car will suddenly increase, stimulating the nerves of the operator, making it more likely to be unable to handle the emergency rationally, increasing the risk factor.
[0004] Currently, most explosion-proof tires reduce the change in tire thickness after a vehicle puncture or blowout by increasing the thickness and hardness of the tire's sidewall, which makes higher requirements on tire production technology and material performance, and increases costs. There is also a method of designing multiple inner tubes. In this method, after a puncture or blowout, especially after the outermost inner tube is punctured or blown, although there is support from other inner tubes, the new energy vehicle will still be instantly unbalanced and the noise will increase, and there is still a major hidden danger. Utility Model Content
[0005] In order to solve the above problems, the utility model proposes a new energy vehicle tire. The tire integrates a multifunctional module body, which not only effectively prevents the problem of tire puncture and explosion, but also enables the vehicle to run relatively smoothly even if the tire is punctured or exploded, effectively reduces noise, reduces danger, enhances the safety, comfort and durability of the tire, and has a positive impact on improving the overall performance of new energy vehicles.
