Embodiment Construction

[0043] Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

[0044] figure 1 Indicates the front body structure of an automobile as a vehicle. Such as figure 1As shown, a pair of square tube-shaped left and right front side beams 1 whose axes are along the vehicle front-rear direction are arranged at the front of the vehicle body in a state along the vehicle front-rear direction, so that the radiator side bracket 2 along the vehicle up-down direction and The front ends of the front side members 1 intersect each other, and a radiator upper bracket 3 along the vehicle width direction W is mounted on the upper ends of a pair of left and right radiator side brackets 2 .

Abstract

The present invention provides a collision energy absorbing box of a vehicle. The collision energy absorbing box of the vehicle is provided with a structure that the box body is crushed before the front collision of the vehicle thereby absorbing the impact energy. The box body is configured between a front beam and a bumper beam at the front side of the vehicle. The box body forms a cylinder shape which is provided with an axial center along the front-and-after direction of the vehicle. A reinforcing beam which connects one pair of opposite wall parts of box body is installed in the hollow part of the box body.

Description

technical field [0001] The present invention relates to a collision energy-absorbing box of a vehicle and a front structure of a vehicle body. At this time, the above-mentioned box body is crushed, thereby absorbing the impact energy. Background technique [0002] In recent years, automobiles have been required to reduce repair costs in the event of minor collisions. This requires that the front side sills not deform in the event of a minor collision; expensive components such as radiators and condensers do not break. Therefore, the crash box is arranged between the front side member and the bumper beam on the front side of the vehicle, and the crash box is crushed to absorb the impact energy in the event of a frontal collision of the vehicle. In addition, by adjusting the crushing residual amount of the crash box (the length of the crash box in the front-rear direction of the vehicle after the collision), there are no expensive parts such as radiators and condensers at th...
