Description

Auto against energy dissipating fender guard
Technical field
The present invention relates to the car protective device field, relate in particular to a kind of auto against energy dissipating fender guard.。
Background technology
Automobile is the most general a kind of transport facility in the present age, popularizes to family and individual gradually.Increasing vehicle travels on highway, and the various traffic accidents of Fa Shenging are also more and more thereupon, car accident especially, and the car crash quantity that causes therefrom is very surprising, causes tremendous loss to the people's lives and property safety.
Present automobile, transport truck particularly, conventional way is that a bumper/spoiler is installed before headstock, but bumper/spoiler and auto body are whole for being rigidly connected, when crashing, be difficult to really play safety effect, its impact force directly affacts on the car and makes car body cause damage, also may cause casualties simultaneously.
Chinese patent CN200710034498.3 discloses a kind of intelligent safety protector for automobile; can overcome the problems referred to above to a certain extent; but the mode of pure shear is partly adopted in the energy dissipating of this protector; when being hit, shear plate can produce a uncertain moment of flexure of direction; make the shear plate bending, energy-absorbing effect is unsatisfactory.
Summary of the invention
Adopt the pure shear mode in order to overcome existing protector energy dissipating; the deficiency that energy-absorbing effect is unsatisfactory; the present invention aims to provide a kind of auto against energy dissipating fender guard; this energy dissipating fender guard is changed into thin-walled box-structure conquassation distortion energy dissipating with existing pure shear energy dissipating; effect of energy dissipation can significantly improve; when bumping; though bump before being or after bump; can both play comprehensive damping, relax impact or eliminate the effect of its impact; when preceding bumping, can realize auto shut down, make automobile and personnel's safety obtain general protection.
To achieve these goals; the technical solution adopted in the present invention is: described collision energy dissipating fender guard; its constructional feature is, comprises front template and rear pattern plate, is provided with at least one can shear-the box energy absorption device of conquassation energy dissipating between described front template and rear pattern plate.
The box energy absorption device of described shearing-conquassation energy dissipating is promptly when automobile is subjected to clashing into, earlier carry out energy dissipating by the multistage shearing of box energy absorption device, remaining afterwards impact continues compressing box energy absorption device, up to the box energy absorption device by conquassation, through shearing energy dissipating earlier, conquassation energy dissipating again can be offset impact significantly, and effect of energy dissipation is good.
Further, described box energy absorption device structure optimization is, comprise that one is fixed in outer rail and on the rear pattern plate and is fixed in interior rail on the front template, should have at least one elongated slot on the interior rail, have a plurality of bolts hole on the described outer rail, the rear sleeve of rail is contained in the front portion of outer rail in described, and by the bolt that passes bolt hole and elongated slot interior rail and outer rail is fixed together.Intensity for rail in strengthening, improve its anti-collision performance, be provided with the cross strengthening rib in the rail in described, have on two floors in this cross strengthening rib with interior rail in the cooresponding chute of elongated slot, described bolt passes from chute, after the box energy absorption device was impacted, bolt can slide in chute, and does not influence shearing motion.The rear portion of described outer rail is provided with a plurality of staggered pin-and-holes, is provided with bearing pin in this pin-and-hole, can hinder the speed that the relative outer rail of slow interior rail slides, and realizes multistage shearing energy dissipating.By this structure, after the box energy absorption device was impacted, interior rail slided along the relative outer rail of elongated slot, shears pivot pin on the outer rail, and after pivot pin had been sheared, interior outer rail produced the conquassation distortion together, realizes effect of energy dissipation.
In order further to improve buffer capacity of the present invention, the protection automobile is provided with at least one spring between described front template and rear pattern plate, and when automobile was subjected to impacting, spring can absorb a part of kinetic energy, plays buffer action.
The present invention mainly is installed in automotive front, wherein said front template is fixedly connected on the automobile front beam, described rear pattern plate is fixedly connected on the car front beam, and described box energy absorption device top is provided with contact switch, and the front end of this contact switch contacts with the push plate that is connected the front template inboard.In case automobile bumps, contact switch is cut off the power supply by the bump of push plate immediately, realizes flame-out.
Certainly, the present invention can also be installed in automobile rear, and wherein said front template is fixedly connected on the automobile rear bumper, and described rear pattern plate is fixedly connected on the automobile back rest, also can protect automobile and personnel's safety when being knocked into the back.
By said structure, the present invention is by recoil spring and box energy absorption device are installed, with the impact of damp impacts generation.In order to deal with huge impact; the thin-walled box-structure is set; conquassation distortion by inside and outside rail absorbs most of collision energy; rail divides multistage staggered bolt and the bearing pin that is installed in the energy dissipating on the outer rail of cutting off simultaneously; interior rail cuts the back with bolt clippers and is out of shape with the outer rail pressurized and by conquassation and the kinetic energy of an absorption part once more; carry out the multi-buffer energy dissipating; with comprehensive mitigation or eliminate its impact; whole buffering energy-absorbing process is steady; can absorb most collision energy, the protection automobile and the personal security of riding.
Compared with prior art; the invention has the beneficial effects as follows: the present invention changes into thin-walled box-structure conquassation distortion energy dissipating with existing pure shear energy dissipating; can make the automobile in travelling after colliding, can realize auto shut down immediately; and can carry out comprehensive automatic damping simultaneously; relax or eliminate its impact; effect of energy dissipation is significantly improved, and has realized the general protection of automobile and personal security, also can effectively protect automobile and personnel's safety when being knocked into the back.
The invention will be further described below in conjunction with drawings and Examples.
