Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model is inadequate for automobile front beam rigidity in prior art, affect the problem of vehicle body safety, a kind of automobile front beam and automobile are provided, by arranging front bumper energy-absorbing plate in the front end of front bumper beam and arranging the buffering longeron be connected with body support in the rear end of front bumper beam, automobile front beam is made to have enough intensity, rigidity and energy-absorbing buffering space; When automobile collides, absorb collision energy by the deformation of the first cushion space and the second cushion space, reduce main body of vehicle frame impaired, save maintenance cost, improve vehicle safety performance.
As shown in Figure 1 and Figure 2, the utility model embodiment provides a kind of automobile front beam, it is characterized in that, comprising:
Front bumper beam 1;
Be coated on the front bumper energy-absorbing plate 2 of described front bumper beam 1 outside face;
Buffering longeron 3 vertically disposed with described front bumper beam 1, the first end of described buffering longeron 3 is connected with described front bumper beam 1, second end of described buffering longeron 3 is connected with body support 4, forms the first cushion space between described front bumper beam 1 and described body support 4;
Wherein, described buffering longeron 3 is arranged multiple distortion guiding groove 31 that there is the second cushion space, guide impact force to transmit towards preset direction.
In the utility model above-described embodiment, automobile front beam crossbeam 1 adopts high tensile steel plate, has high strength and high rigidity.At side (outside face) the coated front bumper energy-absorbing plate 2 of front bumper beam 1 away from body support, when colliding, first front bumper energy-absorbing plate 2 absorbs part energy and impact force is transferred on front bumper beam 1.Further, buffering longeron 3 is set between front bumper beam 1 and body support 4, and buffering longeron 3 arranges distortion guiding groove 31, due to the material that front bumper beam 1 adopts rigidity large, the material that buffering longeron 3 adopts deformability strong, the deformation of front bumper beam 1 then directly can not be caused through the impact force of front bumper energy-absorbing plate 2 absorption portion energy, but due to the material of buffering longeron 3 and the energy of existence meeting by causing the deformation cushioning longeron 3 to carry out double absorption impact force of distortion guiding groove 31, only have when cushioning longeron 3 and reaching largest deformation state, impact force just can be exerted pressure to front bumper beam 1 gradually, make it that deformation occur, simultaneously due to the existence of the first cushion space, first cushion space carries out three times to impact force and absorbs, farthest reduce impact force, the injury of impact force to body support is made to drop to minimum.Such as some less collision cases, the damage of front bumper beam and body support can be avoided, direct exchange buffering longeron, reduce maintenance cost and repair time.
It should be noted that, when vehicle generation head-on crash, distortion guiding groove 31 guides impact force towards longitudinal transmission, and front bumper energy-absorbing plate 2 and buffering longeron 3 can be slightly compressed longitudinally distortion, fully absorb energy, reduce crash acceleration peak value; When vehicle generation side collision, impact force can be deformed guiding groove 31 and guide to vehicle opposite side, thus the passive satety of car load when effectively improving offset collision.
