Anti-collision beam bending resistance detecting device

Abstract

The invention discloses an anti-collision beam bending resistance detecting device. An anti-collision beam is composed of a main beam, a pair of crash boxes and a mounting plate, which are sequentially fixedly connected; the anti-collision beam bending resistance detecting device comprises a base table and a portal frame, wherein the base table is used for mounting the anti-collision beam, the anti-collision beam is fixedly connected with the base table through the mounting plate, and the base table is fixedly connected with a pair of sliding rails; the portal frame is arranged on the base table and slidingly connected with the sliding rails; the anti-collision beam is arranged in a penetrating mode at the bottom of the portal frame; a pressure block for pressing down the main beam is hungon the portal frame. When the anti-collision beam is deformed, the crash boxes can be deformed along to show that strength distribution between the main beam of the anti-collision beam and the crashboxes is uniform; if the main beam of the anti-collision beam is crashed but the crash boxes have no deformation, overlow strength of the main beam can be determined; if the anti-collision beam has nodeformation but the crash boxes are completely crashed, overhigh strength of the main beam can be determined.

Description

technical field [0001] The invention belongs to the technical field of auto parts detection, and in particular relates to an anti-collision beam anti-bending detection device. 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. It is composed of the main beam, the energy-absorbing box, and the mounting plate connected to the car. The main beam and the energy-absorbing box can effectively absorb when the vehicle collides at a low speed. Collision energy, minimize the damage of the impact force to the longitudinal beams of the vehicle body, and thus exert its protective effect on the vehicle. It can be seen that the absorption of collision energy by the anti-collision beam requires the joint action of the main beam and the energy-absorbing box in order to maximize its function. At present, in many car rear-end collision accidents, after the car collides, the main beam of th...

AI Technical Summary

Problems solved by technology

At present, in many car rear-end collision accidents, after the car collides, the main beam of the anti-collision beam is directly crushed and bent, and then directly abuts against the longitudinal beam of the vehicle body, but the energy-absorbing box does not deform, so the energy-absorbing box does not play its role. Some energy absorption, at this time, it can be seen that the strength of the main beam is not enough, so it is necessary to carry out the anti-bending test before the anti-collision beam is installed on the vehicle body, and a special detection device needs to be designed
