Description

Vehicle-mounted device for simulating automobile tire burst

Technical Field

The application relates to the technical field of automobile safety tests, in particular to a vehicle-mounted device for simulating automobile tire burst.

Background

With the popularization of automobiles in life, the traffic accident rate also rises year by year, wherein investigation shows that more than 70% of traffic accidents are caused by tire burst, once the speed per hour of an automobile exceeds 100km/h, if a driver cannot take correct operation within a very short time after the tire burst happens, the driver is likely to directly turn over, the accident death rate of high-speed turning over is currently shown to be close to 100%, and therefore, it is very important that the driver timely takes correct corresponding operation at the moment of the tire burst of the automobile. Therefore, in the training and learning of operation and driving, the simulation demonstration and experience of tire burst for the driver are necessary to ensure that the driver can operate correctly in time when encountering the tire burst accident in the actual driving.

In order to realize the simulation of tire burst, the key is to realize the rapid deflation of the tire, and the following four tire burst test methods are mainly adopted in the related technology: the first is to arrange a tire puncturing device on the road where the vehicle is going, and the tire puncturing device is suitable for security protection; the second is to arrange the deflation conduit device to conduct the tire, seal the deflation conduit with a seal cover under the normal state, open the seal cover with a mechanical mechanism or an electromagnetic valve when the tire bursts, realize rapid deflation to cause the tire burst, which belongs to a vehicle-mounted tire burst device and can remotely or wire control the tire burst, a driver can perform tire burst exercise under the unknown condition, and the tire can be reused; the third is to stick the detonating device with blasting substance on the outside of the tyre, to detonate the blasting substance to pierce the tyre through the remote control device, to realize quick deflation and cause tyre burst, and the fourth is to adopt the device of non-falling nail blasting vehicle-mounted simulating automobile tyre burst, to install the non-falling nail on the suspension, to remotely control the non-falling nail to fall on the advancing road of the tyre, to prick the tyre burst.

However, the above four ways all have certain defects, the first way is to arrange the tire puncture device in advance on the driving road surface of the vehicle, compared with the simulation of tire burst driving exercise, the tire burst device is more suitable for security protection, on one hand, because the tire puncture device is arranged in advance before the test, the driver is likely to instinctively reduce the vehicle speed when approaching the preset tire burst area due to psychological fear, and therefore the vehicle speed required under the condition of high-speed tire burst cannot be actually achieved, the burst and randomness of tire burst are reduced, and the effect of tire burst exercise is weakened; the structure of the second device is complex, rims or hubs required by different vehicle types are different, the device for fixing the air discharge conduit on the rim can rotate along with the tire, and the danger value is high; the third mode has great damage to the tire, and the detonating device is stuck on the tire and rotates along with the tire, so that the detonating device is not firm enough, and has extremely high danger if falling happens carelessly during high-speed driving; the fourth type of nail falling-down prevention prick can not cause the tire to possibly not be able to immediately generate effect after being sunk into the tire, has hysteresis quality, is difficult to get back after the nail falling-down prevention prick has potential safety hazard, and does not accord with laws and regulations if left on a highway.
