Because the safety regulation related to the passenger car is developed slowly, the regulation constraint is not provided, and the research and the coping strategy for the collision safety of the passenger car are less. Since the release of the declaration of passenger protection against frontal collision of passenger cars by the department of transportation, the safety of frontal collision of passenger cars has been gaining attention.
With the improvement of the safety regulation of the passenger car, the protection of passengers in front collision of the passenger car is a main difficulty of safety development of the passenger car, and the injury index of the passengers is strongly related to the deceleration amplitude of the body of the passenger car. Passenger restraint systems for passenger cars mostly only have safety belts and no safety airbags, and the peak value and the average value of the deceleration of a car body must be reduced to reduce the injury index of passengers.
The front collision energy absorption structure of the passenger car can absorb collision energy when the passenger car is in frontal collision, and is a design structure capable of effectively reducing the deceleration peak value and the average value of the car body.
In the prior art, a known passenger car front collision energy absorption structure comprises a passenger car collision energy absorption mechanism or a passenger car collision energy absorption buffer device; wherein:
the passenger car collision energy absorption mechanism comprises an energy absorption box and a buffer rod which is assembled on a passenger car bumper and extends along the front-back direction, and the energy absorption box is fixed on the longitudinal beam. When the bumper is impacted, the buffer rod moves backwards, so that the buffer and energy absorption effects are achieved. Although the passenger car collision energy absorption mechanism can play a role in buffering and energy absorption and reduce the deceleration amplitude of a car body, the application difficulty in the existing car type is high, a front bumper needs to be additionally arranged to be matched with the collision energy absorption mechanism, and other parts cannot be assembled at the corresponding position of the longitudinal beam, so that the passenger car collision energy absorption mechanism is difficult to arrange for a small passenger car.

When the steel plate spring is impacted, the two gas-liquid buffers and the two cement buffers are compressed to play roles in buffering and absorbing energy. Although the collision energy-absorbing buffer device can play a role in buffering and absorbing energy, the collision energy-absorbing buffer device needs more parts, is complex in structure, is heavy in weight and is high in use cost.
