In general, consider a vehicle rollover, which is generally seen in the passive adjustment of the center of gravity. This mechanism is also utilized in the present application due to the use of an inflator. In general, the shock absorbing structure plays a role in assisting the elbow in the process of rollover of the vehicle. The shock absorbing structure prevents a rigid connection of the vehicle body and the axle, because of the relatively flexible nature. However, during cornering, the shock absorbing structure located outside the radius of the curve may further exacerbate the outward deflection of the center of gravity of the vehicle due to centrifugal force.
After the scheme is adopted, the centrifugal force induction switch is always in a normally open state in the running process of the vehicle, but the steering induction switch controls the power-on of the centrifugal force induction switch, so that the centrifugal force induction switch does not work if the vehicle does not turn.
The scheme is provided with the damping air bag, so that the tension spring is arranged to counteract vibration formed by vibration of the vehicle, and the rising of the gravity center of the vehicle body caused by the bouncing of the damping air bag is prevented.
During cornering of the vehicle, if the steering wheel turns sufficiently, the pressure of the steering-assist oil pipe activates the steering-sensitive switch.
At the moment, an inflator pump electrically connected with the steering induction switch is started to start preparation work; the first pressure limiting valves electrically connected with the steering induction switch close the air passage to prevent centrifugal force pressure of the vehicle body from forcing the outer damping air bags to be suppressed.
For ease of explanation we assume that the vehicle is now turning left and centrifugal force is to the right. If the centrifugal force is large, the centrifugal force induction switch is caused to open the left knob. At this time, the left knob opens the exhaust valve of the left shock-absorbing airbag, closes the first intake valve of the left shock-absorbing airbag, and opens the air passage of the right second intake valve. Then, the left side cushion bag starts to exhaust, the pressure limiting value of the right side cushion bag increases, and inflation may start. The possible state of inflation is when the centrifugal force presses the air bag, so that the air pressure of the right shock-absorbing air bag is still below the pressure limiting value. The right tension spring does not work.
In this way, if the centrifugal force is not too great, the cushion airbag is not required to be exhausted to relieve the load of the inflator.
After the turning is completed, the left exhaust valve is closed, the left first air inlet valve is opened, and the left shock absorbing air bag starts to be inflated by the air storage tank. The right second air inlet valve is closed, and the right tension spring starts to work. The first pressure limiting valve begins to operate. In the sloshing of the vehicle running, the tension springs and the first pressure reducing valve at the two sides can balance the two sides finally.
The above is passive center of gravity adjustment to avoid rollover. Because passive adjustment is focused on and cannot work, the whole stress change of the automobile body is actively adjusted, so that the inclination angle of the automobile body is corrected.
The present application provides a system for the explosive jet to counter centrifugal forces, as the electric vehicle body is lighter and the explosive jet can provide sufficient corrective force. Under the condition that the passive gravity center adjustment operation cannot work, the high-pressure air of the air storage tank passes through the communicating pipe with the diameter larger than that of a common vent pipe and is finally quickly released by the air injection valve, so that a reverse thrust capable of resisting the centrifugal force to correct the posture of the vehicle is generated.
The air injection valve is arranged vertically upwards, so that the air flow injected does not affect surrounding occasional peers. In order to prevent the automobile body from being damaged due to the sprayed air flow, noise is brought by the extremely rapid air injection, so that the diffusion air passage is arranged vertically upwards, the automobile body is protected from being damaged by the air flow, and the noise can be guided upwards.
The rapid air injection can generate vibration, so that the shockproof lining piece is arranged; the air injection valve is provided with an annular disc to prevent the reverse thrust from flying out of the air injection valve.
The anti-jet impact frame is arranged to prevent the jet impact force from damaging the structure of the vehicle body, and the anti-jet impact frame is arranged on the damping air bag to directly transmit the impact force downwards to the wheels, so that the longitudinal structure of the vehicle body is prevented from bearing excessive moment bending moment load.
The beneficial effect of this scheme can learn according to the description to above-mentioned scheme, simple structure, reasonable in design can make the electric motor car avoid taking place to turn on one's side when turning, in the turning, not only can reduce the inboard height of turning radius to and make the whole axle of automobile body move to turning radius inboard, can produce the jet-propelled thrust of a burst and resist centrifugal force and correct the automobile body gesture when automobile body inclination is too big moreover.

In general, consider a vehicle rollover, which is generally seen in the passive adjustment of the center of gravity. This mechanism is also utilized in the present application due to the use of an inflator. In general, the shock absorbing structure plays a role in assisting the elbow in the process of rollover of the vehicle. Due to the shock-absorbing structure, a rigid connection of the vehicle body 1 and the axle 2 is avoided, because of the relatively flexible nature. However, during cornering, the shock absorbing structure located outside the radius of the curve may further exacerbate the outward deflection of the center of gravity of the vehicle due to centrifugal force.
After the scheme is adopted, the centrifugal force induction switch is always in a normally open state in the running process of the vehicle, but the steering induction switch controls the power-on of the centrifugal force induction switch, so that the centrifugal force induction switch does not work if the vehicle does not turn.
In the scheme, the damping air bag 3 is arranged, so that the tension spring 30 is arranged to counteract vibration formed by vehicle vibration, and the center of gravity of the vehicle body 1 is prevented from rising due to the bouncing of the damping air bag 3.
During cornering of the vehicle, if the steering wheel is turned sufficiently, the pressure of the steering pipe 19 activates the steering sensor switch.
At the moment, an inflator pump electrically connected with the steering induction switch is started to start preparation work; the first pressure limiting valves 9 electrically connected with the steering induction switch close the air passages so as to prevent centrifugal force pressure of the vehicle body 1 from forcing the outer damping air bags 3 to be suppressed.
For ease of explanation we assume that the vehicle is now turning left and centrifugal force is to the right. If the centrifugal force is large, the centrifugal force induction switch is caused to open the left knob. At this time, the left knob opens the exhaust valve 6 of the left shock-absorbing bag 3, closes the first intake valve 7 of the left shock-absorbing bag 3, and opens the air passage of the right second intake valve 37. Then, the left side cushion airbag 3 starts to exhaust, the pressure limiting value of the right side cushion airbag 3 increases, and inflation may start. The possible state of inflation is when the centrifugal force presses the air bag, resulting in the air pressure of the right shock absorbing air bag 3 being still below the pressure limiting value. The right tension spring 30 does not work.
In this way, if the centrifugal force is not too large, the cushion airbag 3 is not required to be exhausted to relieve the load of the inflator.
After the turning is completed, the left exhaust valve 6 is closed, the left first intake valve 7 is opened, and the left shock absorbing bag 3 starts to be inflated by the air tank 8. The right second intake valve 37 is closed and the right tension spring 30 starts to operate. The first pressure limiting valve 9 starts to operate. In the sloshing of the vehicle running, the two-sided tension springs 30 and the first pressure reducing valve 9 eventually balance the two sides.
The above is passive center of gravity adjustment to avoid rollover. Because passive adjustment is focused on and cannot work, the whole stress change of the vehicle body 1 is actively adjusted to correct the inclination angle of the vehicle body 1.
The present application provides a system in which the explosive jets are resistant to centrifugal forces, just as the electric vehicle body 1 is light and the explosive jets are able to provide sufficient corrective forces. Under the condition that the passive gravity center adjustment operation cannot work, the high-pressure air of the air storage tank 8 passes through the communicating pipe 28 with the diameter larger than that of a common vent pipe and is finally quickly released by the air injection valve 23, so that a reverse thrust capable of resisting the centrifugal force to correct the vehicle posture is generated.
