The invention discloses a multifunctional graded vibration absorption type automobile bumper device. The multifunctional graded vibration absorption type automobile bumper device comprises a bumper shell, damping oil cylinders, a speed sensor and a controller, wherein the speed sensor is electrically connected with the controller; the multifunctional graded vibration absorption type automobile bumper device further comprises a plurality of vibration absorption springs which are located between the bumper shell and a frame transverse beam, and spring fixing seats which are fixed on the frame transverse beam in parallel; and the vibration absorption springs are arranged on the spring fixing seats in a sleeving manner. According to the multifunctional graded vibration absorption type automobile bumper device, the automobile driving speed is detected by the speed sensor; when the automobile driving speed exceeds an over-speed state, piston rods of the damping oil cylinders are controlled by the controller to be at a stretching-out state, so that the anti-collision preparation is made in advance and the collision protection performance is good; a plurality of grades of vibration absorption parts including the damping oil cylinders, the bumper shell, the vibration absorption springs, an energy absorption box and the like are arranged, so that collision energy can be consumed layer by layer in a collision process and the absorption consumption amount of the collision energy is great; and an energy absorption and vibration absorption process is stable, so that the life safety of people in an automobile can be guaranteed.
Description
technical field [0001] The invention relates to an automobile part, in particular to an automobile bumper. Background technique [0002] Existing automobile bumpers generally only have a passive defense function, that is, they can only passively accept collisions, but cannot predict dangerous situations in advance, and do a good job of anti-collision precautions in advance, so their functions for resolving collision risks are not perfect. Performance could still be improved. [0003] And the existing automobile bumper mainly relies on the bumper shell to absorb the collision energy, the shock absorption and energy absorption performance is relatively poor, and the life safety of the personnel in the car cannot be well protected. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a multifunctional graded shock-absorbing car bumper device to solve the problem that the existing car bumper does not have the function of predi...
