Problems solved by technology

Therefore, in the 50kph (per kilometer per hour) side collision test of cars, the test results of ordinary passenger cars are obviously inferior to those of SUVs, that is, the safety of side collisions is lower than that of SUVs.
That is to say, when the car has a side collision, the safety of ordinary passenger cars is not high

Embodiment Construction

[0020] In traditional technology, the basic function of the suspension is to transmit force and moment between the wheel and the frame, and buffer the impact force transmitted to the frame or body from the uneven road, and attenuate the vibration caused by it, so as to ensure the smoothness of the car. Driving, and determines the stability, comfort and safety of the car. All existing suspension systems basically serve this purpose. Among them, there are some suspensions that use air springs, oil-pneumatic springs, etc. as shock absorbers. This type of shock absorber can adjust the stiffness and damping of the shock absorber by changing the amount of internal air and oil-gas compression, thereby slightly adjusting the body and Maintain the posture of the body and ensure stable driving. The shock absorber can adjust the hardness of the air spring and oil-gas spring of the suspension according to the working conditions of the car during driving, so as to prevent some situations t...

Abstract

The invention discloses a suspension and an energy storage spring type chassis lifting mechanism thereof. The energy storage spring type chassis lifting mechanism includes a shock absorber and a lifting device disposed along a height direction, wherein the height direction is consistent with a direction of shock absorbing deformation of the shock absorber; the lifting device includes an energy storage spring, lock-up parts are respectively disposed on two ends of the energy storage spring in the height direction, wherein one of the lock-up parts is located between the shock absorber and the other of the lock-up parts, and is connected to the shock absorber; and the lock-up parts can be locked with each other to maintain the energy storage spring in a compressed state or are unlocked to release the energy storage spring in the height direction. According to the scheme, the height of a chassis can be lifted by releasing the energy storage spring when a situation of side impact occurs, and so, the safety of the side impact is improved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a suspension and an energy storage spring type chassis lifting mechanism thereof. Background technique [0002] With the increase of car ownership, car safety has attracted more and more attention. Statistics show that when a car collides sideways, the fatality rate of occupants in the car is significantly higher than that of a frontal collision. [0003] When a car has a side collision, for an SUV (Sport Utility Vehicle), due to its high chassis, in addition to the body and B-pillar, the chassis can also bear part of the side collision force. For ordinary passenger cars, since their chassis is lower than the general side impact contact area, they cannot bear the side impact force, so only the body and B-pillar can bear the side impact force. Therefore, in the 50kph (per kilometer per hour) side collision test of cars, the test results of ordinary passenger cars are obviously inferio...
