Description
Technical field
The present invention relates to a kind of automobile component, particularly a kind of automobile bumper device.
Background technology
Existing automobile bumper device, is generally the arc shell structure be made up of steel plate punched, and absorb collision energy by the distortion of bumper/spoiler in collision process, its shock absorbing effect, to protect the life security of occupant.
But because existing automobile bumper device depends merely on the distortion of housing to absorb consumption collision energy, therefore its buffering energy-absorbing function is good not enough, it need to improve to the protective capability of occupant and vehicle itself.
And existing automobile bumper device is one-piece construction, and when bumper/spoiler occurs that localized bumps is out of shape, need integral replacing, maintenance cost is higher.
Existing automobile bumper device simultaneously, what have protrudes from outside vehicle body after mounting, in the bad situation of night, causes bumper/spoiler easily to occur wiping the danger of hanging with other vehicle.
Summary of the invention
In view of this, the object of this invention is to provide a kind of automobile bumper device, to solve the problems such as existing automobile bumper device damping energy absorption performance is poor.
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;
The lateral surface of described bumper/spoiler housing is vertically arranged with U-shaped energy-absorbing frid, and be provided with rubber energy-absorbing bar in described U-shaped energy-absorbing frid, described U-shaped energy-absorbing frid and bumper/spoiler housing are bolted.
Further, the biside plate of described U-shaped energy-absorbing frid becomes splayed structure.
Further, the two ends segmental arc medial surface of described bumper/spoiler housing is provided with S shape damping energy-absorbing plate.
Further, the two ends segmental arc lateral surface of described bumper/spoiler housing is provided with reflector.
Further, the height of described damping spring reduces from centre gradually to both sides.
Further, described spring fixed seat is cylindrical rubber post.
Beneficial effect of the present invention:
1, automobile bumper device of the present invention, it is arranged on the damping energy-absorbing function that U-shaped energy-absorbing frid on bumper/spoiler housing and rubber energy-absorbing bar can strengthen bumper/spoiler, improves the passive impact protector ability of bumper/spoiler.
2, automobile bumper device of the present invention, when slight impact, can realize bumper and absorbing shock protective effect by the distortion of U-shaped energy-absorbing frid and rubber energy-absorbing bar, bumper/spoiler housing distortion can be avoided to damage; Simultaneously U-shaped energy-absorbing frid can detachable maintaining, and maintenance cost is low.
3, automobile bumper device of the present invention, it has the multistage composite damping parts such as U-shaped energy-absorbing frid, rubber energy-absorbing bar, 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.
4, automobile bumper device of the present invention, the reflector that its two ends segmental arc lateral surface is arranged can be avoided occurring that extension accident wiped by vehicle at night prompting chaufeur, can improve vehicle safety.

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 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 2 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;
The lateral surface of described bumper/spoiler housing 1 is vertically arranged with U-shaped energy-absorbing frid 7, is provided with rubber energy-absorbing bar 8 in described U-shaped energy-absorbing frid 7, and described U-shaped energy-absorbing frid 7 is connected by bolt 9 with bumper/spoiler housing 1.
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 U-shaped energy-absorbing frid 7, rubber energy-absorbing bar 8, 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; improve the passive impact protector ability of bumper/spoiler, better can ensure the life security of occupant.
And when slight impact, bumper and absorbing shock protective effect can be realized by the distortion of U-shaped energy-absorbing frid 2 and rubber energy-absorbing bar 3, bumper/spoiler housing 1 deformed damaged can be avoided; Simultaneously U-shaped energy-absorbing frid 2 can detachable maintaining, and maintenance cost is low.
