Problems solved by technology

[0003] Traditional car bumpers usually use some rigid shock-absorbing springs to achieve impact resistance and shock absorption purposes. However, this shock-absorbing structure has poor impact resistance and is easily damaged. It cannot guarantee the safety of the internal structure of the car and the life of the driver. At the same time, the existing insurance has insufficient torsion resistance

Abstract

The invention discloses a novel bumper which comprises a bumper body and a steel beam. A damping seat is arranged at the bottom of the bumper body. First damping springs are symmetrically arranged onthe two sides of an inverted-T-shaped groove. A second piston is arranged on the top side of the inverted-T-shaped groove in a sliding and sleeving mode. The two sides of the steel beam are elastically connected with the damping seat through the symmetrical second damping springs respectively. In the novel bumper, part of hitting energy can be counteracted by means of the second damping springs, the rest of energy is first transmitted to damping liquid through a piston rod to be counteracted and finally transmitted to the horizontal symmetrical first damping springs through a first piston to be counteracted, the shaking energy is reduced to the maximum extent, and a certain guarantee is provided for the vehicle structure and the life safety of a driver; meanwhile, through the common effectof a supporting rod and a horizontal third damping spring, torsion resistance of the bumper can be effectively improved, and the structure is effectively protected.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a novel bumper. Background technique [0002] The car bumper is a safety device that absorbs and eases the external impact and protects the front and rear of the car body. Most areas, ostensibly designed to avoid the impact of vehicle exterior damage on vehicle safety systems, have the ability to reduce driver and occupant injuries during high-speed collisions, and are now increasingly being designed for pedestrian protection. [0003] Traditional car bumpers usually use some rigid shock-absorbing springs to achieve impact resistance and shock absorption purposes. However, this shock-absorbing structure has poor impact resistance and is easily damaged. It cannot guarantee the safety of the internal structure of the car and the life of the driver. At the same time, the existing insurance has insufficient torsion resistance. Contents of the invention [0004] The object of t...
