Automobile anti-collision cross beam with high impact resistance

Abstract

The invention discloses an automobile anti-collision cross beam with high impact resistance, and particularly relates to the technical field of anti-collision beams, the automobile anti-collision cross beam comprises a supporting cross beam, energy absorption boxes are fixedly arranged at the two ends of the supporting cross beam, a movable connecting columns ismovably arranged in the energy absorption boxes, the movable connecting column extends out of the energy absorption boxes, and a mounting base is fixedly arranged at one ends of the movable connecting columns an anti-collision beam frame is fixedly arranged between the two mounting bases, and an anti-collision buffer mechanism is arranged between the supporting beam and the anti-collision beam frame; the anti-collision buffering mechanism comprises two elastic supporting frames, and the two elastic supporting frames are symmetrically arranged at the two ends of the supporting cross beam. The middle of the anti-collision beam frame is supported through the two elastic supporting frames and the elastic buffering frame, the elastic deformation buffering capacity of the middle of the anti-collision beam is improved, stepped buffering is conducted on impacts of different degrees in cooperation with the composite foam plastic plate, the anti-impact buffering effect is improved, and follow-up automobile maintenance is facilitated.

Description

technical field [0001] The invention relates to the technical field of anti-collision beams, more specifically, the invention relates to an automobile anti-collision beam with strong impact resistance. Background technique [0002] The anti-collision beam is a device used to reduce the absorption of collision energy when the vehicle is hit by a collision. When the vehicle collides at a low speed, it can effectively absorb the collision energy, and minimize the damage of the impact force to the longitudinal beam of the vehicle body. [0003] The invention patent of the patent application publication number CN201810947407.3 discloses an automobile anti-collision beam, including a main beam, an energy absorbing box and a flange. The main beam is connected to the front longitudinal beam of the car through the flange and bolts. There is an energy-absorbing box, and the left and right ends of the main beam are respectively provided with two mirror-symmetrical side beams. Each sid...

Problems solved by technology

[0004] However, in actual use, there are still many shortcomings. For example, the impact of the anti-collision beam is absorbed by the energy-absorbing box to play a buffering role. However, the middle part of the anti-collision beam lacks a buffering mechanism. The impact on the middle of the anti-collision beam cannot be well buffered, which in turn affects the protective effect of the anti-collision beam
