Abstract
The invention discloses a composite shock absorption type vehicle bumper device. The device comprises a bumper casing body, a plurality of damping springs which are positioned between the bumper casing body and a vehicle frame crossbeam and spring fixing seats fixed on the vehicle frame crossbeam in parallel, wherein the damping springs sleeve on the spring fixing seats, the bumper casing body is connected with the vehicle frame crossbeam through energy absorbing boxes, and the energy absorbing boxes comprise orthohexagonal casings and X-shaped cross boards arranged in the orthohexagonal casings. The composite shock absorption type vehicle bumper device disclosed by the invention is provided with multistage composite shock absorption components such as the bumper casing body, the damping springs and the energy absorbing boxes, so that impact energy can be depleted step by step in an impact process, the absorption and the depletion of the impact energy are larger, the energy absorbing and shock absorbing process is smoother and steadier, and the life safety of people in an vehicle can be ensured better.
Description
Technical field
The present invention relates to a kind of automobile component, particularly a kind of Federal bumper.
Background technology
Existing Federal bumper, it comprises bumper/spoiler housing and the support being connected bumper/spoiler housing and cross member of frame.This automobile Federal bumper only have bumper/spoiler housing the one-level impact absorption energy-absorbing function that rises, damping energy absorption performance is poor, well can not protect the life security of occupant.
Summary of the invention
In view of this, the object of this invention is to provide a kind of composite shock-absorbing formula automobile bumper device, to solve the poor problem of existing Federal bumper damping energy absorption performance.
Composite shock-absorbing formula automobile bumper device of the present invention, comprises bumper/spoiler housing, the spring fixed seat also comprising the some damping springs between bumper/spoiler housing and cross member of frame and be fixed on side by side on cross member of frame, and described damping spring is enclosed within spring fixed seat; Described bumper/spoiler housing is connected with cross member of frame by energy-absorption box, and described energy-absorption box comprises regular hexagon shell and is arranged at the X-shaped cross board in regular hexagon shell.
Further, the height of described damping spring reduces from centre gradually to both sides.
Further, described spring fixed seat is cylindrical rubber post.
Further, S shape energy-absorbing plate is provided with inside the two ends curved portions of described bumper/spoiler housing.
Beneficial effect of the present invention: composite shock-absorbing formula automobile bumper device of the present invention, it has the multistage composite damping parts such as bumper/spoiler housing, damping spring, energy-absorption box, thus collision energy can be consumed step by step in collision process, crash energy absorption consumption is larger, its energy-absorbing shock absorbing process is more steady, better can ensure the life security of occupant.
Accompanying drawing explanation
Fig. 1 is the structural representation of composite shock-absorbing formula automobile bumper device of the present invention;
Fig. 2 is the cross sectional representation of S shape energy-absorbing plate 7.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, the present embodiment composite shock-absorbing formula automobile bumper device, comprise bumper/spoiler housing 1, the spring fixed seat 4 also comprising the some damping springs 3 between bumper/spoiler housing 1 and cross member of frame 2 and be fixed on side by side on cross member of frame 2, described damping spring cover 3 is on spring fixed seat 4; Described bumper/spoiler housing 1 is connected with cross member of frame by energy-absorption box, the X-shaped cross board 6 that described energy-absorption box comprises regular hexagon shell 5 and is arranged in regular hexagon shell 5.
In the present embodiment, the dual-side of the regular hexagon shell 5 of its energy-absorption box is V-arrangement bending plate structure, can in pressurized process quick corresponding damping energy-absorbing, simultaneously the X-shaped cross board 6 of energy-absorption box inside can further improve its damping energy absorption performance.
The present embodiment composite shock-absorbing formula automobile bumper device, owing to being provided with the multistage composite damping parts such as bumper/spoiler housing 1, damping spring 3, energy-absorption box, thus collision energy can be consumed step by step in collision process, crash energy absorption consumption is larger, energy-absorbing shock absorbing process is faster, better can ensure the life security of occupant.
As the improvement to the present embodiment; the height of described damping spring 3 reduces from centre gradually to both sides; in collision process; the first contact-impact thing of damping spring 3 at middle part; then the spring contact-impact thing successively again of both sides, middle part; impact absorption endergonic process is more steady, and buffering effect is better, better can protect the life security of occupant.
As the improvement to the present embodiment, described spring fixed seat 4 is cylindrical rubber post, and cylindrical rubber post also has damping energy-absorbing function, and it can the phase absorbs and consumes collision energy, the further barrier propterty improving automobile bumper device after an impact.
As the improvement to the present embodiment, be provided with intensity and damping energy absorption ability that S shape energy-absorbing plate 7, S shape energy-absorbing plate 7 can improve bumper/spoiler housing 1 both sides inside the two ends curved portions of described bumper/spoiler housing 1, improve the side shield performance to automobile.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
