Intake valve.

Usually, people consider the rollover of the vehicle, and the general vision lies in the passive adjustment of the center of gravity. This application also utilizes this mechanism due to the use of an air pump. Generally speaking, the shock-absorbing structure plays a role in helping the tyrant when the vehicle rolls over. Because the shock absorbing structure avoids the rigid connection of the body and the axle, it is more flexible. However, during the turning process, due to the centrifugal force, the shock absorbing structure located on the outside of the turning radius will back compress and further aggravate the outward deflection of the vehicle's center of gravity.

After adopting this scheme, when the vehicle is running, the centrifugal force sensing switch is always on, but since the steering sensing switch controls the energization of the centrifugal force sensing switch, the centrifugal force sensing switch does not work if there is no turning.

Because the shock-absorbing airbag is provided in this program, an extension spring is provided to eliminate the vibration caused by the vehicle vibration and prevent the bouncing of the shock-absorbing airbag from causing the center of gravity of the vehicle body to rise.

When the vehicle is turning, if the steering wheel is turned sufficiently, the pressure in the power steering hose will activate the steering sensor switch.

At this time, the air pump electrically connected to the steering sensor switch starts to start preparations; the first pressure limiting valve electrically connected to the steering sensor switch all closes the air passage to prevent the centrifugal force of the vehicle body from forcing the outer shock-absorbing airbag to hold back.

For the sake of illustration, we assume that the vehicle is turning left at this moment, and the centrifugal force is to the right. If the centrifugal force is large, the left knob should be opened by the centrifugal force sensor switch. At this time, the left knob opens the exhaust valve of the left shock absorber airbag, closes the first intake valve of the left shock absorber airbag, and opens the air passage of the second right intake valve. As a result, the left airbag begins to deflate, and the pressure limit value of the right airbag increases and may begin to inflate. The possible state of inflation is when the air pressure of the right shock-absorbing airbag is still below the pressure limit value due to the compression of the airbag by the centrifugal force. Right side tension spring does not work.

In this way, if the centrifugal force is not too large, there is no need to exhaust the shock-absorbing airbag to reduce the burden on the inflator.

After the turn is completed, the left exhaust valve is closed, the first left intake valve is opened, and the left shock absorber air bag is inflated by the gas storage tank. The second intake valve on the right is closed, and the right extension spring starts to work. The first pressure limiting valve starts to work. During the shaking of the vehicle running, the tension springs on both sides and the first pressure reducing valve will finally balance the two sides.

The above content is passive center of gravity adjustment to avoid rollover. Because this application focuses on passive adjustment, it cannot be effective, and actively adjusts the overall force change of the vehicle body to correct the inclination angle of the vehicle body.

Just because the body of the electric vehicle is relatively light, and the explosive jet can provide sufficient correcting force, the application provides a system for resisting centrifugal force by the explosive jet. When the passive center of gravity adjustment operation fails, the high-pressure air from the gas storage tank passes through a connecting pipe with a diameter larger than that of the general air pipe, and finally is quickly released by the jet valve, thereby generating a reverse thrust that can resist centrifugal force and correct the vehicle's attitude.

The jet valve is set vertically upwards to consider that the jet air flow will not affect the occasional companions around. In order to prevent the jet air from damaging the body, and the extremely fast jet will cause noise, the diffuser air duct is set up vertically, which not only protects the air from damaging the body, but also guides the noise upward.

Extremely fast air jets will generate vibrations, so anti-vibration linings are installed; the jet valve is provided with an annular disc to prevent the jet valve from flying out due to reverse thrust.

The purpose of setting up the anti-jet impact frame is to prevent the jet impact force from damaging the body structure, and the anti-jet impact frame is set on the shock absorbing airbag to transmit the impact force directly downward to the wheels, preventing the moment when the longitudinal structure of the vehicle body is overloaded. Bending moment load.

The beneficial effect of this scheme can be known according to the description of the above scheme. The structure is simple and the design is reasonable, which can prevent the electric vehicle from rolling over when turning. The relative axle moves to the inner side of the turning radius, and can generate an explosive jet reverse thrust to resist centrifugal force and correct the posture of the vehicle body when the vehicle body tilt angle is too large.

Usually, people consider the rollover of the vehicle, and the general vision lies in the passive adjustment of the center of gravity.

Due to the shock-absorbing structure, the rigid connection of the vehicle body 1 and the vehicle axle 2 is avoided, because it is more flexible. However, during the turning process, due to the centrifugal force, the shock absorbing structure located on the outside of the turning radius will back compress and further aggravate the outward deflection of the vehicle's center of gravity.

After adopting this scheme, when the vehicle is running, the centrifugal force sensing switch is always on, but since the steering sensing switch controls the energization of the centrifugal force sensing switch, the centrifugal force sensing switch does not work if there is no turning.

Since the shock-absorbing airbag 3 is provided in this program, an extension spring 30 is provided to eliminate the vibration formed by vehicle vibration and prevent the bouncing of the shock-absorbing airbag 3 from causing the center of gravity of the vehicle body 1 to rise.

The possible state of inflation is when the air pressure of the right shock-absorbing airbag 3 is still below the pressure limit value due to the compression of the airbag by the centrifugal force.

During the shaking of the vehicle running, the tension springs 30 on both sides and the first decompression valve 9 will eventually balance the two sides.

The above content is passive center of gravity adjustment to avoid rollover. Since this application focuses on passive adjustment, it cannot be effective, and actively adjusts the overall force change of the vehicle body 1 to correct the inclination angle of the vehicle body 1 .

Just because the body 1 of the electric vehicle is relatively light, and the explosive jet can provide sufficient corrective force, the present application provides a system for resisting centrifugal force by the explosive jet. When the passive center of gravity adjustment operation fails, the high-pressure air from the gas storage tank 8 passes through the connecting pipe 28 whose diameter is larger than that of the general air pipe, and finally is quickly released by the air injection valve 23, thereby generating a reverse thrust that can resist centrifugal force and correct the vehicle attitude .
