Problems solved by technology
The existing bumper is directly installed and fixed on the front and rear ends of the chassis. When the car collides with the car, because there is no buffer effect, the collision kinetic energy will cause great damage to the car and the people in the car.
[0003] The invention patent with the patent number ZL200520009521.X discloses a car with an automatic extension anti-collision device. In its technical solution, the bumper can extend and retract by itself, and the power for extending and retracting is provided by a high-pressure gas cylinder , because the high-pressure gas cylinder will occupy a large space in the car, so this technical solution cannot be applied to gasoline / natural gas hybrid vehicles (because the natural gas cylinder has occupied the space in the car)
And when the car collides with the car, due to the conditioned reflex of the driver, the position where the car collides with the car occurs at the side corner of the bumper in many cases. Hydraulic shock absorber - the hydraulic cylinder is installed towards the front of the car, and it basically has no buffering effect on the oblique impact force. Therefore, this technical solution will reduce the damage to the car and the people in the car when the car collides. The effect is still not obvious

Embodiment Construction
[0034] Such as figure 1 and figure 2 As shown, the automobile anti-collision bumper system includes a bumper, a hydraulic shock absorber, a bumper action control device and a control circuit of the action control device. The bumper is composed of a base and an inflatable air bag 3 fixed on the base. The bar base is made up of a middle front section 20 and two side rear sections 19, and the two side rear sections 19 are respectively hinged at the two ends of the middle front section 20, and its hinge point 21 is positioned at the turning point of the bumper base. A positive shock absorber 1 is fixed at the front end of the chassis, and a forward hydraulic shock absorber 2 is installed and fixed on the forward shock absorber 1. The forward hydraulic shock absorber 2 is a hydraulic cylinder, which consists of a cylinder body, a piston and a piston rod. Composition, the piston is provided with a one-way valve, when the piston rod is extended outward, the one-way valve is opened,...

The invention relates to a vehicle anti-collision bumper system which comprises a bumper, a hydraulic damper, a bumper action control device and a control circuit of the action control device, wherein a base of the bumper is formed by hinging three sections. The anti-collision bumper system can have good buffering and damping effects no matter that a vehicle has a collision in a positive direction or an oblique direction so as to effectively reduce damages to the vehicle and people in the vehicle. Moreover, the power of the anti-collision bumper system is provided by a motor, and a transmission mode of gear and rack as well as chain wheel and chain is adopted, thus the anti-collision bumper system can be arranged on vehicles comprising gasoline / natural gas hybrid electric vehicles.
Description
technical field [0001] The invention relates to a supporting device of an automobile, in particular to an automobile anti-collision bumper system installed on the automobile. Background technique [0002] The bumper is located at the front and rear of the car and is the main point of contact in car-to-car collisions. Existing bumper is directly installed and fixed on the front and rear ends of the car chassis, and when cars collide with cars, because there is no cushioning effect, the collision kinetic energy will cause great damage to cars and people in cars. [0003] The invention patent with the patent number ZL200520009521.X discloses a car with an automatic extension anti-collision device. In its technical solution, the bumper can extend and retract by itself, and the power for extending and retracting is provided by a high-pressure gas cylinder , because the high-pressure gas cylinder will occupy the larger space in the car, so this technical scheme can not be applica...
