Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of automobile front beam.
Background technology
Along with the progress of society, the raising of people's living standard, automobile more and more becomes the important vehicle of people's trip, and the safety performance of automobile also more and more obtains the concern of people.
Existing automobile, is generally equipped with front bumper at the leading section of automobile, when front bumper, in running process, head-on crash occurs, can provide certain protective effect for automobile.Existing automobile front protecting danger, generally comprises one or two crossbeams arranged along vehicle right and left direction, and crossbeam is connected with the headstock of automobile mutually by some short and small pipe links.
But the automobile front beam of this kind of structure; because crossbeam can not be too heavy; therefore; crossbeam is generally be made up of hollow tubular; when automobile generation slight impact, certain protective effect can be played, but when violent collision occurs automobile; crossbeam can be hit flat headstock that is direct and automobile and be fitted, and the protected effect played automobile is very little.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides a kind of automobile front beam, solves the protected effect how making existing automobile front beam play when automobile generation sharp impacts good.
The purpose of this utility model realizes by following technical proposal: a kind of automobile front beam, automobile comprises headstock, the front end of described headstock is fixed with adapter plate, it is characterized in that, described front bumper comprises crossbeam and a pair pipe link, the length of described crossbeam and the width in vehicle right and left direction match, one end of pipe link described in a pair is all connected mutually with crossbeam, the other end is all connected mutually with the headstock of automobile, described pipe link has conquassation groove near one end of crossbeam, energy absorber is provided with in described pipe link, described energy absorber is connected on a mounting board, described crossbeam and the junction of pipe link are provided with Impactor.
Automobile front collides, and when impact is smaller, namely front bumper is not knocked the position of laminating headstock, and now conquassation groove can not by conquassation; When impact is larger; because conquassation groove is lower relative to the firmness of other positions of crossbeam and pipe link; conquassation groove is preferentially by conquassation; now Impactor strikes on energy absorber; energy absorber absorbs the impulsive force that collision produces; the impulsive force produced when effectively reducing automobile impacting, plays the good protective effect of automobile.
In above-mentioned a kind of automobile front beam, described energy absorber comprises cylinder, spring, stopper and baffle plate, described stopper is connected in the head of cylinder piston rod, described baffle plate is connected in the outside of cylinder piston rod near cylinder block place, described spring housing is in the outside of piston rod, and one end of spring is resisted against on baffle plate, the other end is resisted against in stopper.The piston rod of cylinder is stretched outside, cylinder is preset with certain power, after the power be subject to when piston rod exceedes this power preset, piston rod just can be pushed back in cylinder body, this process just alleviates the impulsive force falling part collision and cause, when piston rod bounces back, baffle plate is resisted against on cylinder body, when piston rod retracts in cylinder body again, baffle plate is washed out, and now spring is compressed the effect also providing elastic force to play buffering, alleviates the impulsive force that automobile produces due to collision, reduce the deformation quantity of automobile, reduce injury when automobile collides, driver, occupant caused.
In above-mentioned a kind of automobile front beam, described crossbeam and pipe link are made by hollow tubular.Hollow tubular lighter weight, can not increase the complete vehicle weight of automobile, and the headstock of automobile can not be made heavier.
In above-mentioned a kind of automobile front beam, described Impactor is column, and the medial surface of the face, outer circumferential of Impactor and crossbeam fits.The shape of Impactor and the mating shapes of crossbeam, be conveniently installed in crossbeam by Impactor, flush fit between Impactor and crossbeam, makes Impactor can not move when driving, can not offset initial position, good stability.
In above-mentioned a kind of automobile front beam, have limiting stopper in described crossbeam, described limiting stopper is positioned at the both sides of Impactor.The stability of Impactor is strengthened in the existence of limiting stopper further, makes Impactor offset initial position.
In above-mentioned a kind of automobile front beam, described adapter plate is strip.The length of adapter plate and the width of headstock left and right directions match, and adapter plate is made up of metallic material and thicker, can not bend, and be installed to difficult drop-off after headstock, the firmness that energy absorber is installed is high.
Compared with prior art, a kind of automobile front beam that the utility model provides has the following advantages:
1, this automobile front beam arranges energy absorber, conquassation groove and Impactor, and make automobile when there is sharp impacts, conquassation groove is by conquassation; Impactor impact energy absorption device; energy absorber absorbs the impulsive force that collision produces, and reduces the injury of colliding and causing automobile, plays a very good protection.
2, the Impactor of this automobile front beam and crossbeam flush fit are connected, and at Impactor in crossbeam, a limiting stopper is each side set, double shield, ensure that the position of Impactor can not offset, the good stability of Impactor, Impactor all the time with energy absorber just to setting.
