Embodiment 1

[0027] A safety device for reducing vehicle tire blowout and side collision intrusion injuries, including a cylinder 5 located between a vehicle body 14 and an axle 6, a pressure limiting valve 12, a pressure relief valve 13, a gas detonator 11, a connecting cylinder 5 and a gas The gas pipeline 4 of the detonating device 11, the tire pressure monitoring sensor, the electronic control unit, and the lateral radar;

[0028] At the suspension on each side of the car, a cylinder 5 is arranged in parallel with the shock absorber system. The shock absorber system includes a shock absorber 3 and a spring 2, and the spring 2 is sleeved on the outside of the shock absorber 3; one end of the shock absorber system and the cylinder 5 is connected to the vehicle body 14, and the other end of the shock absorber system is connected to the axle 6 with the piston rod;

[0029] The cylinder 5 is composed of a piston and a cylinder body, and the piston is inserted into the cylinder body to form ...

Embodiment 2

[0047] The control method of the above-mentioned safety device, its steps include,

[0048] (1) The tire pressure sensor detects the tire pressure and sends the tire pressure data to the electronic control unit;

[0049] (2) The electronic control unit receives tire pressure data, and sends a trigger signal to the trigger end of the gas detonator 11 when it detects that the tire pressure drop rate reaches a preset value;

[0050] (3) The lateral radar detects the distance to the adjacent vehicle, and sends the distance data to the electronic control unit;

[0051] (4) The electronic control unit receives the distance data, and sends a trigger signal to the trigger end of the gas detonator 11 when it detects that the distance data reaches a preset value

[0052] (5) After the gas detonation device 11 receives the trigger signal, the sodium azide 10 in the gas detonation device 11 explodes to generate nitrogen gas;

[0053] (6) The nitrogen gas is transported to the inner cavi...

Abstract

The invention discloses a safety device used for reducing vehicle tire bursts and side collision intrusion damage. The safety device comprises air cylinders, gas detonation devices, gas pipelines, tire pressure sensors and an electric control unit, all of which are arranged between a vehicle body and axles, wherein the gas pipelines connect the air cylinders with the gas detonation devices. The air cylinders are arranged at the position of suspensions of all sides of a vehicle in the manner that the air cylinders are connected with vibration avoidance systems in parallel. Each air cylinder is composed of a piston and a cylinder body, wherein the piston is sleeved with the cylinder body to form an inner cavity. The inner cavity of each air cylinder is connected with an air outflow hole of the corresponding gas detonation device through the corresponding gas pipeline. Each tire pressure sensor monitors the pressure in a corresponding tire and sends tire pressure data to the electric control unit. The electric control unit is connected with the trigger ends of the gas detonation devices and receives the tire pressure data, and when it is detected that the tire pressure descending speed reaches a preset value, the electric control unit sends trigger signals to the trigger ends of the gas detonation devices. The invention further discloses a control method of the safety device. By the adoption of the safety device, when one tire bursts, the flat tire is pressed downwards in time, and a chassis is lifted up before a side collision happens. The safety device is simple in structure and low in cost, the purposes of tire burst emergency control and side collision intrusion reduction are achieved, and the comfort of the vehicle is not sacrificed.

Description

technical field [0001] The invention belongs to the technical field of automobile safety protection, and in particular relates to a vehicle tire blowout and side collision intrusion reduction device. The invention also relates to the vehicle tire blowout and the control method for reducing side collision intrusion. Background technique [0002] Statistics show that the proportion of traffic accidents caused by tire blowouts on the road every year reaches 20%, and the number of deaths caused by high-speed driving tire blowouts accounts for 49.81% of the death toll in expressway accidents. The pendulum is out of control. At the moment of a tire blowout, the wheels are suspended in the air and cannot provide support. The vehicle forms a rollover moment under the action of gravity to tilt the vehicle. The driver often slams on the steering wheel and brakes violently out of instinct, causing the vehicle to lose control and yaw. Even roll over. The prior art adopts tire pressure...
