Description

Vehicle tire repair method, vehicle and tire Technical Field The application relates to the technical field of tire repair, in particular to a vehicle tire repair method, a vehicle and a tire. Background In the self-repairing tires widely used in the current electric vehicles and fuel vehicles, a technical scheme of coating high-viscosity sealant (such as butyl rubber-based material) on the inner wall of a tire body is generally adopted. When sharp foreign matters such as nails, screws and the like penetrate into the tire, the sealant can rapidly wrap the outer wall of the foreign matters to form temporary sealing, so that the tire pressure is maintained, and immediate pressure loss is avoided. However, once the foreign matter is pulled out, the original puncture hole loses nails as a supporting framework, and the lining sealant is insufficient in elasticity and the like, so that the hole is reopened, a tiny open leakage channel is formed, and gas slowly leaks at a slower speed. And the process has extremely strong concealment, and the tire pressure monitoring system usually sets an alarm threshold value to be about 25% of the tire pressure drop, and the alarm is triggered only when slow air scattering can take hours. Therefore, when a user runs at a high speed or in a long distance, the tire pressure is difficult to detect and slightly reduced, but the tire side wall is repeatedly deformed due to continuous low pressure, so that overheat and structural fatigue are caused, and finally, the tire burst is caused, and the risk is extremely high. Disclosure of Invention The present application aims to solve at least one of the technical problems in the related art to some extent. Therefore, a first object of the present application is to provide a vehicle tire repairing method, which can accurately identify specific airflow characteristics formed after foreign matters are pulled out through real-time monitoring of airflow conditions in a tire, wherein the airflow conditions of the target characteristics are key basis for judging that a puncture hole is in an open leakage state. Once such characteristics are monitored, the control trigger mechanism is immediately started, and even if the repairing agent packaging body is damaged or incomplete in the previous foreign body penetrating or pulling-out process, the repairing agent can be ensured to flow rapidly and accurately and be filled into the damaged part of the tire under the natural action of the air pressure inside the tire. The active repairing mechanism can complete the blocking of the leakage channel before the tire pressure is obviously reduced to the alarm threshold, so that potential risks of overheating of the tire side wall, structural fatigue and the like caused by slow air scattering are fundamentally eliminated, the safety of vehicle running is obviously improved, particularly, the active repairing mechanism plays an effective role in preventing hidden danger of tire burst in a high-speed or long-distance running scene, avoids tire burst risks caused by slow reduction of the tire pressure, and improves the safety and stability of vehicle running. To achieve the above object, an embodiment of a first aspect of the present application provides a method for repairing a vehicle tire, the tire including a repairing agent package and a triggering mechanism, wherein the repairing agent package includes a repairing agent, and the triggering mechanism is used for destroying the package integrity of the repairing agent package, the method includes monitoring an air flow state inside the tire, and controlling the triggering mechanism to be activated when the air flow state of a target feature inside the tire is identified, so that the repairing agent is released when the repairing agent package is incomplete, wherein the repairing agent is filled to a damaged part of the tire under the action of the air pressure inside the tire. According to the vehicle tire repairing method, the air flow state in the tire is monitored, and when the air flow state with the target characteristic in the tire is identified, the triggering mechanism is controlled to be started, so that the repairing agent is released under the condition that the repairing agent package body is incomplete, wherein the repairing agent is filled to the damaged part of the tire under the action of the air pressure in the tire. Therefore, the method can avoid the tire burst risk caused by slow drop of the tire pressure, and improve the safety and stability of vehicle running. According to one embodiment of the application, the method further comprises determining a state of the air flow identifying the presence of the target feature inside the tire in case the air flow continues beyond a preset time threshold, the direction of the air flow is directed from the tire cavity to the outside of the carcass and the speed of the air flow is within a preset speed interval. According to one embodiment of the
