Abstract
The invention discloses a grading damping type automotive bumper device. The grading damping type automotive bumper device comprises a bumper shell, a plurality of damping springs and spring fixing seats, wherein the damping springs are arranged between the bumper shell and a vehicle frame crossbeam, and the spring fixing seats are fixed on the vehicle frame crossbeam in parallel; the damping springs sleeve the spring fixing seats. The grading damping type automotive bumper device comprises multistage damping components such as the bumper shell, the damping springs, the spring fixing seats and the like, so that collision energy can be consumed step by step in the collision process; the absorption consumption of the collision energy is relatively high, so that the energy-absorption damping process is relatively smooth, and the life safety of people in an automobile can be well guaranteed.
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 vehicle beam.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 classification damping type automobile bumper device, to solve the poor problem of existing Federal bumper damping energy absorption performance.
Classification damping type automobile bumper device of the present invention, classification damping type automobile bumper device, comprise 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, described damping spring is enclosed within spring fixed seat.
Further, the height of described damping spring reduces from centre gradually to both sides.
Further, described spring fixed seat is cylindrical rubber post.
Further, described bumper/spoiler housing is connected with vehicle beam by energy-absorption box.
Further, described energy-absorption box is bellows-like structure.
Beneficial effect of the present invention: classification damping type automobile bumper device of the present invention, it has the Multistage 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 classification damping type automobile bumper device of the present invention.
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 classification damping type 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.
The present embodiment classification damping type automobile bumper device, it has the Multistage damping parts such as bumper/spoiler housing 1, damping spring 2, 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.
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 consumption collision energy further after an impact, the further barrier propterty improving automobile bumper device.
As the improvement to the present embodiment, described bumper/spoiler housing 1 is connected with vehicle beam 2 by energy-absorption box 5, by energy-absorption box 5 Absorbable rod collision energy, can further improve the barrier propterty of this automobile bumper device.
As the improvement to the present embodiment, described energy-absorption box 5 is bellows-like structure, and structure is simple, and energy-absorbing effect is good.
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.
