According to the multifunctional graded vibration absorption type automobile bumper device, the automobile driving speed is detected by the speed sensor; when the automobile driving speed exceeds an over-speed state, piston rods of the damping oil cylinders are controlled by the controller to be at a stretching-out state, so that the anti-collision preparation is made in advance and the collision protection performance is good; a plurality of grades of vibration absorption parts including the damping oil cylinders, the bumper shell, the vibration absorption springs, an energy absorption box and the like are arranged, so that collision energy can be consumed layer by layer in a collision process and the absorption consumption amount of the collision energy is great; and an energy absorption and vibration absorption process is stable, so that the life safety of people in an automobile can be 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, generally all only has Passive Defence function, and namely it can only passive acceptance collision, and can not shift to an earlier date anticipation dangerous situation, and carries out crashproof defence in advance, and thus it is perfect not enough to the function dissolving collision risk, and performance need to improve.
And existing Federal bumper, the main bumper/spoiler housing that leans on absorbs collision energy, and 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 multi-functional classification damping type automobile bumper device, to solve the function that existing Federal bumper does not have anticipation danger, crashproof preparation can not be carried out in advance and the problem such as damping energy absorption performance is poor.
The present invention's multi-functional classification damping type automobile bumper device, comprise bumper/spoiler housing, also comprise the damping oil cylinder be arranged on cross member of frame, the speed sensor of inspection vehicle wheel speed and the controller of control damping oil cylinder, described speed sensor and controller electrical connection, the piston rod end of described damping oil cylinder is provided with flexible block, and the middle part of described bumper/spoiler housing is provided with the window coordinated with flexible block;
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, described multi-functional classification damping type automobile bumper device also comprise be fixed on cross member of frame and with the orienting sleeve of damping oil cylinder piston rod bearing fit.
Further, described bumper/spoiler housing is connected with cross member of frame by energy-absorption box.
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, the present invention's multi-functional classification damping type automobile bumper device; its Negotiation speed sensor detects automobile driving speed; when automobile driving speed is in overspeed condition; the piston rod that controller just controls damping oil cylinder is in the state of stretching out; thus crashproof preparation can be carried out in advance; when colliding generation; damping oil cylinder can consume part impinges energy in advance; then in further knockout process, vehicle bumper shell consumes remaining Impact energy more further; thus better can protect the life security of occupant, impact protector performance is better.
2, the present invention's multi-functional classification damping type automobile bumper device, it has the Multistage damping parts such as damping oil cylinder, 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 the present invention's multi-functional classification damping type automobile bumper device.
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 multi-functional classification damping type automobile bumper device, comprise bumper/spoiler housing 1, also comprise the damping oil cylinder 3 be arranged on cross member of frame 2, the speed sensor 4 of inspection vehicle wheel speed and the controller 5 of control damping oil cylinder, described speed sensor 4 and controller 5 are electrically connected, the piston rod end of described damping oil cylinder 3 is provided with flexible block 6, and the middle part of described bumper/spoiler housing 1 is provided with the window coordinated with flexible block 6;
The spring fixed seat 8 also comprising the some damping springs 7 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 7 is enclosed within spring fixed seat 8.
In normal state, the piston rod of damping oil cylinder 3 stretches out certain distance makes flexible block 6 flush with bumper/spoiler housing 1, can not affect the outward appearance of bumper/spoiler.When speed sensor 4 detects that automobile driving speed is in overspeed condition; the piston rod that controller 5 just controls damping oil cylinder 3 is in and entirely stretches out state; thus crashproof preparation can be carried out in advance; when colliding generation; damping oil cylinder 3 can consume part impinges energy in advance; then in further knockout process, vehicle bumper shell consumes remaining Impact energy more further, thus better can protect the life security of occupant, and impact protector performance is better.
And the present embodiment multi-functional classification damping type automobile bumper device, it has the Multistage damping parts such as damping oil cylinder 3, bumper/spoiler housing 1, damping spring 7, 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, this multi-functional classification damping type automobile bumper device also comprise be fixed on cross member of frame 2 and with the orienting sleeve 9 of damping oil cylinder 3 piston rod bearing fit; Orienting sleeve 9 can avoid the problems such as the piston rod of damping oil cylinder 3 deflects, the piston distortion of damping oil cylinder 3 in collision process, better can ensure that damping oil cylinder 3 normally works.
As the improvement to the present embodiment, described bumper/spoiler housing 1 is connected with cross member of frame 2 by energy-absorption box 10; Energy-absorption box 8 can consume Impact energy further, improves bumper/spoiler protection energy.
As the improvement to the present embodiment, the height of described damping spring 7 reduces from centre gradually to both sides; In collision process, the first contact-impact thing of damping spring 7 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 8 is cylindrical rubber post; 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.
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.
