Flat-head truck bumper capable of absorbing impact kinetic energy

Abstract

The invention relates to a flat-head truck bumper capable of absorbing impact kinetic energy, which belongs to the field of automobile accessories, and is characterized in that a plurality of disc-shaped rubber buffer airbags are transversely arranged in front of a rectangular frame side by side, and a bumper made of rectangular high-density resin and a steel wire mesh is arranged in front of the buffer airbags; a cuboid-shaped cab is arranged above the front surface of the frame; a groove is transversely and vertically formed in the middle of the front portion of a cab, a plurality of rectangular buffering air cushions are transversely and vertically installed in the groove, and a rectangular middle net made of resin materials is installed in front of the buffering air cushions. The lower portion of each buffering air cushion is connected with the upper portion of the corresponding buffering air bag below through a cylindrical rubber pipeline, and the interiors of the buffering air cushions are communicated. When the bumper of the flattop truck is impacted, the bumper extrudes the rear buffer air bag backwards instantly, and the buffer air bag starts to be compressed quickly and absorbs kinetic energy to release internal air to the buffer air cushion from the rubber pipeline.

Description

technical field [0001] The invention relates to a bumper of a flat-top truck capable of absorbing impact kinetic energy, belonging to the field of automobile accessories, in particular to a bumper of a flat-top truck capable of rapidly absorbing kinetic energy after being hit. Background technique [0002] Flathead truck, a kind of cargo truck with the cab in front of the head. Because of its spacious interior and wide view, it is popular among drivers. However, flat-head trucks have inherent design defects, that is, there is no good impact buffer area in front of the cab, and the grille and bumper in front of the cab are far away from the driver. The occupants are relatively close, and there is no effective impact kinetic energy absorption facility. If a flat-head truck collides head-on, it is easy to cause serious injuries to the occupants. The bumpers of most existing trucks are basically made of glass fiber reinforced plastics, which only play an aesthetic role, and the...

Problems solved by technology

Because of its spacious interior and wide view, it is popular among drivers. However, flat-head trucks have inherent design defects, that is, there is no good impact buffer area in front of the cab, and the grille and bumper in front of the cab are far away from the driver. The occupants are relatively close, and there is no effective impact kinetic energy absorption facility. If a flat-head truck collides head-on, it is easy to cause serious injuries to the occupants.

The bumpers of most existing flat-head trucks are basically made of fiberglass, which is only for aesthetic purposes, and the impact kinetic energy absorbed by the impact is very limited.
