The weight of entire vehicle body front beam can be reduced using aluminum alloy materials, so as to reduce the weight of whole automobile.
The section bar includes riser and two level boards being oppositely arranged, and the thickness of the riser and the level board is 1.8~2.0mm;
The riser is connect with two level boards.
By experimental verification, using the plank of 1.8-2.0mm thickness, in the case where ensureing sufficient intensity, additionally it is possible to most The overall weight of vehicle body front beam is reduced in big degree.
Further, the girder is arc-shaped, and the arc cylinder cambered surface of the girder is used to carry impact force.
After main beam design camber, when automobile is knocked, the exterior arc surface of girder is by impact force
Further, the free end of first connector and the free end of second connector are both provided with through-hole, use It is bolted in vehicle body.
Further, the bumper holder includes connecting plate and two support plates, and the connecting plate is used to connect with bumper It connects, the support plate is connected to the both sides of the connecting plate;
Two support plate layer angle settings, the connecting plate are connect by the support plate with the girder.
A kind of automobile, the automobile include vehicle body and above-mentioned vehicle body front beam, and the forepart of the vehicle body is provided with first and indulges Beam and the second longeron, first longeron are connect with first connector, and second longeron connects with second connector It connects.
The advantageous effect of technical solution of the present invention is:
The vehicle body front beam obtained by above-mentioned design, since the first connector and the second connector are removable with girder respectively Unload connection so that assembling is more convenient;And the overall structure of vehicle body front beam is fairly simple, so as to reduce vehicle body front beam Cost.
The automobile obtained by above-mentioned design, since automobile employs above-mentioned vehicle body front beam so that automobile integral into This reduction, and it is all more convenient to replace maintenance.
