Utility model content
The purpose of this utility model is to provide a kind of automobile and bumper/spoiler thereof, to solve the problem of the dismounting inconvenience between existing energy-absorbing cylinder and bumper/spoiler.
For achieving the above object, the technical scheme of the utility model Federal bumper is:
A kind of Federal bumper, comprise the bumper body that length extends in left-right direction, the rear end of bumper body is convexly equipped with backwards for the boss of identical positioning and plug-in mounting in the front end endoporus of corresponding energy-absorbing cylinder.
The upper end of described bumper body is provided with the articulated structure that the hinge axes for being hinged and connected with car body extends in left-right direction.
Described energy-absorbing cylinder comprises outer cylinder body, inner barrel and the connecting panel for being coupled together by inside and outside cylindrical shell, and described boss is inserted in the front end of energy-absorbing cylinder inner barrel.
Outer cylinder body, inner barrel and connecting panel have identical length.
The shape of inner barrel is cylindrical shape.
The technical scheme of the utility model automobile is:
A kind of automobile, comprise car body, energy-absorbing cylinder and Federal bumper, Federal bumper comprises the bumper body that length extends in left-right direction, and the rear end of bumper body is convexly equipped with backwards for the boss of identical positioning and plug-in mounting in the front end endoporus of corresponding energy-absorbing cylinder.
The upper end of described bumper body is provided with the articulated structure that the hinge axes for being hinged and connected with car body extends in left-right direction.
Described energy-absorbing cylinder comprises outer cylinder body, inner barrel and the connecting panel for being coupled together by inside and outside cylindrical shell, and described boss is inserted in the front end of energy-absorbing cylinder inner barrel.
Outer cylinder body, inner barrel and connecting panel have identical length.
The shape of inner barrel is cylindrical shape.
The beneficial effects of the utility model are: by arranging boss on bumper/spoiler, the mode of plug-in mounting is adopted to position installation to energy-absorbing cylinder, without the need to carrying out elasticity bolt operation in the finite space between bumper/spoiler and car body, be convenient to the dismounting between energy-absorbing cylinder and bumper/spoiler, it also avoid simultaneously in running car energy-absorbing cylinder due to front end unsettled and occur the situation of up-down vibration.
Further, in vehicle maintenance and repair, bumper body can be come around hinge upset, be convenient to change energy-absorbing cylinder.
Further, the outer cylinder body of energy-absorbing cylinder, inner barrel and connecting panel three have identical length, and the distortion of the inside and outside cylindrical shell of such collision energy-absorbing cylinder can be synchronous, adds stability during collision.Inner barrel is set to cylindrical shape, and boss is the cylindrical boss coincide with inner barrel shape, is convenient to manufacture.
Accompanying drawing explanation
Fig. 1 is Federal bumper schematic diagram of the present utility model;
Fig. 2 is the structural representation of energy-absorbing cylinder in Fig. 1;
Fig. 3 is the scheme of installation of energy-absorbing cylinder in Fig. 1.
Detailed description of the invention
The specific embodiment of the utility model automobile, as shown in Figure 1 to Figure 3, comprise car body, energy-absorbing cylinder 1 and Federal bumper, Federal bumper comprises the bumper body 3 that length extends in left-right direction, and the rear end of bumper body 3 is convexly equipped with boss 9 backwards; The upper end of bumper body 3 arranges hinge 5, and bumper body 3 is hinged on car body by hinge 5, and the hinge axes of hinge 5 extends in left-right direction.Energy-absorbing cylinder 1 comprises outer cylinder body 11, inner barrel 12 and the connecting panel 13 for being coupled together by inside and outside cylindrical shell, and outer cylinder body 11 is eight-sided formation, and inner barrel 12 is cylindrical shape, and boss 9 matches with the shape of inner barrel 12, is inserted in the front end of inner barrel 12.
By arranging boss at Federal bumper, the mode of plug-in mounting is adopted to position installation to energy-absorbing cylinder, not be used in the small space between bumper/spoiler and car body and carry out elasticity bolt operation, be convenient to the dismounting between energy-absorbing cylinder and bumper/spoiler, it also avoid simultaneously in running car energy-absorbing cylinder due to front end unsettled and occur the situation of up-down vibration.In vehicle maintenance and repair, bumper body can be come around hinge upset, be convenient to change energy-absorbing cylinder.
In the present embodiment, outer cylinder body 11, inner barrel 12 and connecting panel 13 three have identical length, and the distortion of the inside and outside cylindrical shell of such collision energy-absorbing cylinder can be synchronous, adds stability during collision.Inner barrel 12 is set to cylindrical shape, and boss 9 is the cylindrical boss coincide with inner barrel 12 shape, is convenient to production and processing.The induction groove 7 for absorbing collision energy is all had at the equal length place of the front end of inner barrel 12, outer cylinder body 11, induction groove 7 can make energy-absorbing cylinder 1 that the Folding Deformation of " accordion " formula of rule occurs, can play and well be out of shape energy-absorbing function, prevent fitfull distortion and cause whole energy-absorbing cylinder enter flexural deformation pattern and lose original energy absorption capacity.
In the present embodiment, rear end adapter plate 2 has and the mounting hole 8 of outer cylinder body 11 same size size and four bolts hole, mounting hole 8 is octagon hole, the rear end of outer cylinder body 11 is through mounting hole 8, with the equal full weld of rear end adapter plate about 2 two layers of surface, by two-layer welding, effectively can prevent energy-absorbing cylinder 1 and rear end adapter plate 2 when there is the offset collision of certain degree of overlapping from producing at weld and tear phenomenon.Rear end adapter plate 2 is connected to by four bolts on the vehicle frame 4 in car body.
In the present embodiment, boss 9 is made up of rubber, uses flexible material to be convenient to the nested installation of energy-absorbing cylinder 1.
In other embodiments, being articulated and connected between bumper body and car body can also adopt other articulated structures except hinge, as the relatively turnable structure that bearing pin and hole are formed.
