Detailed description of the invention
The specific embodiment of vehicle frame of the present utility model, as shown in Figures 1 to 4, comprise support body, front endergonic structure 6 and the automobile-used energy absorption device link span for being connected support body and front endergonic structure 6, link span is bifurcation structure 5, comprise the fixed end for being connected with vehicle frame support body of rear end, fixed end is connected with by backward front the first extension arm 51 and the second extension arm 52 extended, the front end of each extension arm is the coupling end be connected with front endergonic structure 6, each coupling end is all in staggered distribution in the vertical direction mutually with fixed end, and each coupling end is all positioned at the outside of fixed end on above-below direction or left and right directions.
In the present embodiment, bifurcation structure 5 is the opening structure in " Y " font in perpendicular forward.Therefore, endergonic structure 6 setting height(from bottom) before the improving or reduce of bifurcation structure 5, increases collision energy-absorbing region, and when colliding, front endergonic structure 6 deformable absorbs collision energy, can play one's part to the full.Front endergonic structure 6 is provided with groove, is beneficial to be out of shape energy-absorbing.
The support body of vehicle frame comprises front side member 1 and intermediate longitudinal girder 2, and the top of front side member 1 is driver zone 101, and the top of intermediate longitudinal girder 2 is passenger zone 201.Front side member 1 is fixed with front endergonic structure 6 by bifurcation structure 5, intermediate longitudinal girder 2 comprises the upper intermediate longitudinal girder 21 and lower intermediate longitudinal girder 22 that are distributed in front side member about 1 both sides, support body also comprises raker beam 3, raker beam 3 comprises the upper raker beam 31 for fixing front side member 1 and upper intermediate longitudinal girder 21 and the lower raker beam 32 for fixing front side member 1 and lower intermediate longitudinal girder 22, one end of raker beam 3 is fixed on the rear portion of front side member 1, the other end is fixedly connected with the front end of intermediate longitudinal girder 2, the rear endergonic structure 7 at the rear being positioned at front side member 1 is installed with between upper intermediate longitudinal girder 21 and lower intermediate longitudinal girder 22.In collision process, raker beam 3 can make a part for impact load be distributed on intermediate longitudinal girder 2.
In the present embodiment, front side member 1 comprises front side member and lower front side member, is fixed with front vertical beam 8 between upper and lower front side member, is fixed with the first vertical beam 9, second vertical beam 10, the 3rd vertical beam 11 between upper and lower intermediate longitudinal girder from front to back successively.Be provided with to be positioned between rear endergonic structure 7, second vertical beam 10 at front side member 1 rear and the 3rd vertical beam 11 between the first vertical beam 9 be fixedly connected with the rear end of front side member 1 and the second vertical beam 10 and be provided with vertical pole 13 and brace 14, vertical pole 13 and brace 14 are section bar.Rear endergonic structure 7 is also provided with groove, and under the inducing action of groove, endergonic structure can produce the distortion of conquassation step by step to absorb collision energy.
When vehicle strikes rigid objects at a relatively high speed, with rigid objects generation relativity.As shown in Figure 3, impact load, before being delivered to vehicle frame front side member 1, is first delivered on front endergonic structure 6, and front endergonic structure 6 produces conquassation distortion absorption portion energy.Impact load continues to be delivered on front side member 1 along bifurcation structure 5, be delivered on raker beam 3 and rear endergonic structure 7 by front side member 1, therefore a part of impact is delivered on intermediate longitudinal girder 2 by raker beam 3, another part impact is then delivered on rear endergonic structure 7 along front side member 1, the rear endergonic structure 7 with the function absorbing collision energy and transmitted load produces distortion and absorbs again local collision energy, and the impact of remnants is reasonably diverted on section bar below, make front side member and intermediate longitudinal girder that bending distortion not easily occur, the chaufeur of top and the living space of occupant are ensured, thus protect the safety of chaufeur and occupant.When front part of vehicle collides, endergonic structure produces stable conquassation step by step, absorbs most of collision energy; crash acceleration reduces greatly; and adopt the load transfer path of two-stage endergonic structure, can realize absorbing collision energy more, improve the ability of protection occupant.
In other embodiments, link span can also be the opening bifurcation structure in " Y " font in horizontal plane forward; The extension arm of link span, except angled straight lines is extended, also can be extended by backward forward position curvature or broken line extension; Link span also can comprise plural extension arm.As long as link span can meet the effect played and increase collision energy-absorbing region.
