AI Technical Summary

Technical Problem

The existing automobile bumper lower guard plate structure has poor protection effect, is easily damaged by collision, and has high maintenance costs.

Method used

A durable automobile bumper lower guard plate is designed, which adopts a buffer layer and a reinforcement plate structure. The buffer layer is made of soft silicone material, and the bottom reinforcement plate is a hollow modular plate. It is connected to the anti-collision beam through a buffer mechanism. The buffer spring realizes energy absorption and dispersion, and the connection mechanism avoids direct pulling of the bumper.

Benefits of technology

It improves the collision energy absorption and dispersion effect, reduces the probability of bumper damage, reduces maintenance costs, and extends the service life of the equipment.

Abstract

The utility model discloses a durable lower protective plate of an automobile bumper, and relates to the technical field of automobile parts. A buffering layer is arranged at the lower end of the main protection plate, a bottom reinforcing plate is arranged at the lower end of the buffering layer, buffering mechanisms are symmetrically arranged on the left side and the right side of the upper end of the main protection plate, connecting mechanisms are arranged at the upper ends of the buffering mechanisms, and the buffering mechanisms are connected with an anti-collision beam through the connecting mechanisms. The buffer layer made of a soft silica gel material is adopted, so that collision energy is effectively absorbed and dispersed; a bottom reinforcing plate is arranged at the lower end of the buffering layer, when the bottom reinforcing plate collides with stones, the safety of the main protection plate can be further guaranteed, meanwhile, the bottom reinforcing plate is designed to be of a hollow structure, the overall protection and buffering effects of the device are greatly guaranteed, and then the service life of the device is prolonged; when the main protection plate and the bottom reinforcing plate are subjected to large impact, the connecting plate and the sliding plate move upwards, then buffering of impact acting force is achieved, and traction to the bumper is effectively avoided.
