Problems solved by technology

As a result, excessive stress concentration occurs around the connecting portion, so there is a possibility of fracture around the connecting portion or fastening bolts
[0012] In addition, due to the excessive restraint reaction force in the prior art, there is a possibility of fracture around the connecting portion of the front down protector 12 and the bracket 01

Abstract

The shock-absorbing structure has a protector comprising: a front downside protector connected to the body frame by brackets, the structure has sufficient strength to resist the impact and is flexible to attenuate the impact, thereby avoiding Fracture caused by impact. The structure is provided with a protective device (12) on the front end or rear end of the body frame (100) of the vehicle for receiving the impact force when colliding with the opposite vehicle (200), wherein the bracket (1) includes: The vehicle body connection part (3) is used to connect to the vehicle body frame (100); the protector connection part (4) is used to connect to the protector (12); and is used to connect the body frame connection part (3) to the protector connection The connecting plate part (5) of the part (4), the connecting plate part (5) extends vertically and longitudinally along the automobile; The installation position of the device connection part (4) is lower than the position of the cutout part (2).

Description

technical field [0001] The present invention is applied to automobiles, such as heavy trucks, and relates to a shock absorbing structure. When a passenger car or the like collides with the automobile, the protective device supported by a bracket connected to the front or rear of the vehicle body can absorb the shock load. Background technique [0002] A large automobile such as a heavy truck is provided with a front underrun protector on a bumper at the front of the vehicle and a rear bumper at the rear of the vehicle to absorb the impact load by the front underrun protector or the rear bumper to prevent When a large truck collides head-on with a passenger car, etc., or a passenger car hits the rear of a large car, the hit passenger car enters under the large vehicle. [0003] There are also vehicles with a structure in which the front down protector and the rear bumper are connected to the lower surfaces of the front and rear cross members or the left and right side cross m...
