Description
Technical field
Technical field of automobile accessories is the utility model is related to, more particularly to a kind of back buffer beam for automobile.
Background technology
Back buffer beam for automobile protects body structure as automobile safe component in low speed collision, can be to greatest extent
Reduce the maintenance cost of vehicle；Portion of energy is absorbed in high velocity impact, reduces the extent of injury to occupant.Generally, in vehicle
The air that flows through of rear of trailing wheel be rolled-up during the traveling of vehicle, because irregular diffusion results in vortex,
So, air is deteriorated in the flowing of rear view of vehicle.If air is deteriorated in the flowing of rear view of vehicle, the negative of the vehicle back side is acted on
Pressure increase, the overall running resistance increase of vehicle, causes the reduction such as fuel economy of vehicle.
The content of the invention
It is of the present utility model to be directed to problems of the prior art and defect, there is provided a kind of reasonable in design, manufacture craft
Simple back buffer beam for automobile.
To achieve the above object, technical scheme is used by the utility model：A kind of back buffer beam for automobile, including anticollision
Beam body, the thin-wall construction that the collision prevention girders body is formed in one, its U-shaped profile, the collision prevention girders body edge
Outside flange is equipped with, several protuberances equidistantly arranged are equipped with the upper surface of the collision prevention girders body and bottom surface
Portion, the mounting hole for connection body crossbeam is opened up at the protrusion end face center, nut inserts is embedded in the mounting hole；
Wherein, on the flange for extending to its edge the protrusion on the upper surface is since in the middle part of it, positioned at the bottom
On the flange that protrusion on face extends to its edge since its middle part；Two car plates are opened up on the left of the collision prevention girders body
There are the ventilation slot of two opening upwards formed at two to lower hem, and the anticollision in mounting hole, its upper surface left and right sides respectively
Energy-absorbing chamber is set in the middle part of beam body upper surface and leading flank junction, the collision prevention girders body internal surface be provided with more horizontal bars and
Energy-absorbing post is provided with the rubber of the cross reinforcement energy-absorbing muscle that vertical bars are crossed to form, the horizontal bar and vertical bars.
In the above-mentioned technical solutions, before described ventilation slot extends to collision prevention girders body by the collision prevention girders body upper surface
Side, air vent is provided with the bottom land of the ventilation slot, the air vent is located on the leading flank of the collision prevention girders body.
In the above-mentioned technical solutions, the cross section of described protrusion is trapezoidal.
In the above-mentioned technical solutions, described collision prevention girders body and the flange Integral mold positioned at collision prevention girders body edge
It is molded.
The beneficial effects of the utility model are：The utility model can be incited somebody to action by setting ventilation slot on back buffer beam top
Wind positioned at automobile back wheel rear is discharged, and suppresses the generation of vortex, and so as to reduce vehicle travel resistance, and the utility model is one
Body formula structure, stable mechanical property, and compression molding is used, technique is simple, Stability Analysis of Structures, the utility model back buffer beam body
Middle and upper part sets energy-absorbing chamber, and energy-absorbing can be effectively realized in the presence of stress, ensure that the security of driving.
