AI Technical Summary
Traditional anti-collision beam energy-absorbing boxes usually use the strength of the energy-absorbing box itself to complete the energy-absorbing. The lack of an auxiliary energy-absorbing structure, resulting in the energy-absorbing effect still needs to be improved.
A car -collision beam suction box is designed. There are multiple groups of energy absorbers in the interior, including liquid storage cavity, connecting channels, piston connecting boards, supporting rods, energy absorption fans and elastic telescopic materials. These components expand and explode through hydraulic oil, rotating fans and elastic materials during impact, disperse and transform energy, and improve energy absorption effects.
Through the dispersal of energy, the uniformity and energy absorption effect of the energy absorption box is improved, and the absorption and safety performance of the impact force is enhanced.

Abstract
Description
Technical Field
[0001] The invention relates to the technical field of automobile equipment, in particular to an energy absorption box for a front anti-collision beam of an automobile. Background Art
[0002] The working principle of the energy absorption box of the anti-collision beam is based on the law of conservation of energy. When a vehicle collides, the impact force acts on the energy absorption box, which converts kinetic energy into internal energy (mainly heat energy) through deformation such as compression and bending, thereby reducing the impact force transmitted to the longitudinal beam of the vehicle body and the passengers in the vehicle, reducing the risk of injury to the people in the vehicle.
[0003] Traditional anti-collision beam energy absorption boxes usually use the strength of the energy absorption box itself to absorb energy, lack of auxiliary energy absorption structure, and the energy absorption effect needs to be improved. Summary of the invention
[0004] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides an energy absorption box for a front bumper beam of an automobile, which solves the problem that traditional energy absorption boxes for front bumper beams usually absorb energy using the strength of the energy absorption box itself, lack an auxiliary energy absorption structure, and the energy absorption effect needs to be improved.
[0005] (II) Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: an energy absorption box for a front anti-collision beam of an automobile, comprising an energy absorption box body, wherein a plurality of energy absorption mechanisms are arranged inside the energy absorption box body, wherein the energy absorption mechanism comprises a liquid storage cavity, wherein both left and right sides of the liquid storage cavity are connected with connecting channels, wherein one end of the connecting channel away from the liquid storage cavity is connected with the side wall of the energy absorption box body, wherein a piston connecting plate is arranged inside the connecting channel, wherein one end of the piston connecting plate away from the liquid storage cavity is fixedly connected with a support rod, wherein one end of the support rod away from the piston connecting plate extends to the outside of the energy absorption box body and is fixedly connected with the support plate, and two adjacent liquid storage cavities are connected with each other through a pressure transmission channel.
[0006] Preferably, energy-absorbing fans are provided inside the connecting channel and the pressure-transmitting channel.
[0007] Preferably, the side walls of the liquid storage cavity are provided with a plurality of elastic and retractable materials.
[0008] Working principle: During use, when the energy absorption box receives impact, the support plates on both sides of the energy absorption box will transfer energy to each support plate through the support rod, the piston connecting plate and the filled hydraulic oil to disperse the energy, improve the force uniformity of the energy absorption box, and improve its energy absorption effect. When the hydraulic oil is flowing, it can drive the energy absorption fan to rotate, convert part of the energy into mechanical energy, and further improve the energy absorption effect. When it is subjected to a severe impact, the elastic telescopic material on the side wall of the liquid storage cavity will expand, which can also improve the energy absorption effect. When the impact reaches the limit, the elastic telescopic material will explode, and the hydraulic oil will splash to absorb the generated heat, further improving the safety performance.
[0009] (III) Beneficial effects The present invention provides an energy absorption box for a front anti-collision beam of an automobile, which has the following beneficial effects: 1. The energy absorption box of the front anti-collision beam of the automobile. When the energy absorption box is impacted, the support plates on both sides of the energy absorption box will transfer energy to each support plate through the support rod, the piston connecting plate and the filled hydraulic oil to disperse the energy and improve the force uniformity of the energy absorption box. Today, its energy absorption effect is improved. When the hydraulic oil is flowing, it can drive the energy absorption fan to rotate, convert part of the energy into mechanical energy, and further improve the energy absorption effect.
[0010] 2. When the front anti-collision beam energy absorption box of the automobile is subjected to a violent impact, the elastic and telescopic material on the side wall of the liquid storage cavity will expand, which can also improve the energy absorption effect. When the impact received reaches the limit, the elastic and telescopic material will explode, and the hydraulic oil will splash to absorb the generated heat, further improving the safety performance.
