Detailed description of the invention
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with accompanying drawing, the present invention is further detailed.
As in Figure 3-5, the embodiment of the present invention provides a kind of auto body, it comprises left-side assembly 21, right side wall assembly 22, rear floor assembly, hat rack assembly and hat rack vertical beam, rear floor assembly and hat rack assembly are all connected between left-side assembly 21 and right side wall assembly 22, and the two ends of hat rack vertical beam are fixed with hat rack assembly and rear floor assembly respectively.This hat rack vertical beam roughly vertically extends, and it can be set to one, also can be set to many, and the connection location of this hat rack vertical beam and hat rack assembly and rear floor assembly can be arranged flexibly according to concrete structure.
When generation tail touches, the impact force that rear floor assembly is subject to is not passed to the front of vehicle body by means of only rear floor assembly, be also passed on hat rack assembly by hat rack vertical beam, then makes the direction of transfer of impact force increase to some extent, can disperse impact force as early as possible.Obviously, compared to the content introduced in background technology, it is less that the hat rack vertical beam that the present invention increases makes rear row passenger personnel touch at tail the injury be subject in process.
In specific embodiment, rear floor assembly can comprise the left longeron in rear floor 23, rear floor right vertical beam 24, rear floor crossmember 25, rear floor crossmember 25 is connected between the left longeron in rear floor 23 and rear floor right vertical beam 24, hat rack vertical beam comprises the first vertical beam 26 and the second vertical beam 27, first vertical beam 26 is fixed with the left longeron 23 in rear floor, and the second vertical beam 27 is fixed with rear floor right vertical beam 24.In this structure, be connected between rear floor assembly and hat rack assembly by the first vertical beam 26 and the second vertical beam 27 simultaneously, make tail touch in process, the bang path of impact force is more, and then after reducing to a greater degree, row passenger personnel touch the injury be subject in process at tail.
Further, the first vertical beam 26 can be fixed on the left longeron in rear floor 23 for connecting the position of rear floor crossmember 25.The left longeron in rear floor 23 has higher structural strength with the connection location place of rear floor crossmember 25, and after the first vertical beam 26 is connected to this position, the structural strength of the first vertical beam 26 is higher, and then makes the structural strength of whole vehicle body higher.In like manner, the second vertical beam 27 can be fixed on for connecting the position of rear floor crossmember 25 on rear floor right vertical beam 24, to strengthen above-mentioned technique effect.
The concrete structure of aforementioned first vertical beam 26 and the second vertical beam 27 can be arranged arbitrarily, such as, be set to the rectangular beam that cross sectional shape is rectangle.In the embodiment of the present invention, the first vertical beam 26 and the second vertical beam 27 all can be set to U-shaped beam, and the open side of the first vertical beam 26 is towards the open side of left-side assembly 21, second vertical beam 27 towards right side wall assembly 22.After so arranging, the weight of the first vertical beam 26 and the second vertical beam 27 is relatively light, and both structural strengths also can meet the demands.
Usually, first vertical beam 26 and the second vertical beam 27 adopt the mode of welding to assemble with rear floor assembly, but, when the first vertical beam 26 and the second vertical beam 27 are U-shaped beam, first vertical beam 26 and will form enclosed construction between the second vertical beam 27 and rear floor assembly, cannot use welding gun to carry out welding operation.For this reason, the first vertical beam 26 is connected with left longeron 23 plug welding of rear floor, and the second vertical beam 27 is connected with right vertical beam 24 plug welding of rear floor, to realize the reliable fixing of each part mentioned above.
In preferred embodiment, the hat rack 30 that the hat rack assembly that the embodiment of the present invention provides can comprise rear seat back crossbeam 28, rear air regulator roof drip crossbeam 29 and be connected between rear seat back crossbeam 28 and rear air regulator roof drip crossbeam 29, hat rack vertical beam is fixed on rear seat back crossbeam 28.Rear seat back crossbeam 28 has higher structural strength, after hat rack vertical beam and rear seat back crossbeam 28 are fixed, both and rear floor assembly form space frame structure, the torsional stiffness of vehicle body is increased, disperse impact force by a larger margin simultaneously, reduce passenger personnel with this and touch the injury be subject in process at tail.
The embodiment of the present invention also provides a kind of automobile, and this automobile comprises the auto body described by above-mentioned arbitrary technical scheme.Because above-mentioned auto body has above-mentioned technique effect, the automobile comprising this auto body also should have corresponding technique effect, repeats no more herein.
Mode above only by illustrating describes some one exemplary embodiment of the present invention, undoubtedly, for those of ordinary skill in the art, when without departing from the spirit and scope of the present invention, can revise described embodiment by various different mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the claims in the present invention protection domain.
