Description

Novel bumper of automobile

Technical Field

The invention relates to a bumper, in particular to a novel automobile bumper, and belongs to the technical field of automobile accessories.

Background

The automobile bumper is a safety device for absorbing and relieving external impact force and protecting the front part and the rear part of an automobile body. The front and rear bumpers of the automobile are stamped into channel steel by steel plates and riveted or welded with the frame longitudinal beam for many years, and a large gap is reserved between the channel steel and the automobile body, so that the front and rear bumpers of the automobile are quite unattractive. With the development of the automobile industry and the extensive use of engineering plastics in the automobile industry, automobile bumpers have also been revolutionized as an important safety device. The front and rear bumpers of the sedan car of today are required to be harmonious and unified with the shape of the car body and to be light in weight in itself, besides maintaining the original protection function. The front and rear bumpers of a car are all made of plastic and are called plastic bumpers. The plastic bumper of a common automobile consists of three parts, namely an outer plate, a buffer material and a cross beam. Wherein the outer plate and the buffer material are made of plastics, and the cross beam is punched into a U-shaped groove by a cold-rolled sheet; the outer plates and the cushioning material are attached to the cross member.

The invention discloses a barrier net detachable bumper with a Chinese patent number of CN 201610727675.5.A barrier net is arranged on the middle section of the upper body of the bumper, blocks sand in the front of a vehicle body and is beneficial to protecting the front side of the vehicle body; the middle section of the upper body of the bumper is detachably connected with the longitudinal beam of the frame, so that the middle section of the upper body of the bumper can be conveniently detached to clean the blocking net and the license plate;

for another example: chinese patent No. CN201720792783.0 proposes a multiple-protection high-safety bumper, when the automobile is impacted, the bumper is damped and buffered in multiple ways, the buffering performance is good, the safety coefficient is high, however, in the above patents, the bumper is mostly installed in a fixed manner between the constituent structures, the bumper is partially damaged, the whole bumper is also replaced or maintained, time and labor are wasted, the cost is also increased, meanwhile, the mesh density of the blocking net of the bumper is large, although the bumper has a good dustproof effect, the fluidity of gas is not high, the heat generated by the front cover engine of the automobile cannot be effectively dissipated, meanwhile, the bumper in the prior art is only composed of one layer of shell plate, and the plastic shell is mostly used as the protection bumper, the buffering effect for the impact force is weak, when the impact of high-speed and high-kinetic energy occurs, the bumper is difficult to absorb the impact force, and will cause the accident, therefore, a novel bumper for the automobile is provided.
