Abstract
This invention relates to an anti-shock bumper used by cars, in which, the front baffle of a car hidden anti-shock bumper is adhered inside of its outer frame, two buffer devices in the same structure are installed at its ends separately, guide ways are opened on the corresponding positions of the two side walls on the lateral direction of the baffle guiding piece, which slides freely with the fixed guiding screw rod on the connecting unit of the car and the guiding ways, the side walls of the connecting unit are fixed with the car body edge arms and the end is fixed with buffer rubber, a buffer spring is set around the buffer rubber and between the front baffle and the connecting unit, which applies three sets of progressive deformation buffer design and fully uses the physical impact toughness and dynamics.
Description
Technical field
The present invention relates to Federal bumper, particularly a kind of anti-impact bumper of auto use.
Background technology
At present; there is not the reload buffer device between tradition car bumper and vehicle body; dynamic ductility and mechanical structure do not play buffering and safety effect to vehicle body; cause vehicle when bumping, can not protect vehicle body and driver and conductor's safety effectively, and directly installing external crash barrier additional at the vehicle body front and back ends influence the attractive in appearance of car.
Summary of the invention
The object of the present invention is to provide and a kind ofly can be complementary with many sedans, and can be with the Adelomorphic anti-collision bumper of car of impact force efficient absorption, it is under the condition that does not change the original bumper/spoiler surface structure of car and the stealthy inside that is assemblied in forward and backward bumper/spoiler is similar shape with original bumper/spoiler and coincide.
The objective of the invention is to realize: Adelomorphic anti-collision bumper of car by following approach, front apron is fitted and is installed in bumper/spoiler housing inboard, the two ends of front apron are installed with an identical in structure shock absorber respectively, have guide groove on the correspondence position of the baffle plate guide horizontal direction in this shock absorber, the baffle plate guide utilizes guide spiro rod fixing on the body contact spare to be free to slide by guide groove, the sidewall of body contact spare and vehicle body side bar are fixed, be fixed with yielding rubber on the termination of body contact spare, the periphery of yielding rubber is equipped with recoil spring, and recoil spring is between front apron and body contact spare; The center fixation that the central authorities of front apron choose steel by cushion rubber bumper and arc spring, arc spring are chosen the pulley of steel by its two ends and are fixed on the orientating box rolling touch of body contact spare on leaning to one side.The installed inside of orientating box has folding shape pressure locking plate.Recoil spring, and the plastics balance pad is set between the front apron.Folding shape pressure shell fragment is installed on the body contact spare madial wall, and the high spot of this folding shape pressure shell fragment is against the termination of baffle plate guide.
Adelomorphic anti-collision bumper of car of the present invention has adopted three groups of gradual distortion Cushioning Design, fully uses physical impact toughness and mechanics advantage.Can be with the impact force efficient absorption 80% of car.Its front apron is to adopt elasticity manganese steel to make through mould and technology, it by with the connecting of baffle plate guide, again through guide groove and guide spiro rod and body contact spare formation single shaft sliding structure, be that head-on crash or monolateral collision all have rational distortion activity, recoil spring is the pressure assembling, has the double action that cushions and reset for front apron, spring is chosen steel does not have assembling pressure, after producing pressure, collision can further improve the dynamic ductility and the buffering efficient of baffle plate, the usable length of yielding rubber accounts for 80% of mounting distance, it is the last buffer action that produces in collision, recoil spring and spring being chosen the buffering surplus energy of steel does further to decompose to absorb, and actv. keeps soft contact the between vehicle body and the collision body, cause secondary injury in order to control shock absorber because of collision reaction, the present invention chooses steel to recoil spring and spring and is provided with the pressure locking plate to reduce the bounce-back speed and strength of shock absorber.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described in further detail:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A section-drawing of Fig. 1;
Fig. 3 is the B-B section-drawing of Fig. 1;
Fig. 4 chooses the structural representation of steel 6 for spring.
The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, Adelomorphic anti-collision bumper of car of the present invention, front apron 11 is fitted and is installed in bumper/spoiler housing 10 inboards, the two ends of front apron 11 are installed with an identical in structure shock absorber respectively, have guide groove 12 on the correspondence position of baffle plate guide 9 horizontal directions in this shock absorber, baffle plate guide 9 utilizes guide spiro rod 4 fixing on the body contact spare 2 to be free to slide by guide groove 12, the sidewall of body contact spare 2 and vehicle body side bar 1 are fixing, be fixed with yielding rubber 8 on the termination of body contact spare 2, the periphery of yielding rubber 8 is equipped with recoil spring 13, and recoil spring 13 is between front apron 11 and body contact spare 2; The center fixation that the central authorities of front apron 11 choose steel 6 by cushion rubber bumper 7 and arc spring, arc spring are chosen the pulley 16 of steel 6 by its two ends and are fixed on orientating box 5 rolling touch of body contact spare 2 on leaning to one side.The installed inside of orientating box 5 has folding shape pressure locking plate 15.Recoil spring 13, and plastics balance pad 14 is set between the front apron 11.Folding shape pressure shell fragment 3 is installed on body contact spare 2 madial walls, and the high spot of this folding shape pressure shell fragment 3 is against the termination of baffle plate guide 9.
The principle of work of Adelomorphic anti-collision bumper of car of the present invention is as follows: the car that is equipped with this Adelomorphic anti-collision bumper is when being collided, original bumper/spoiler housing 10 of car, the stressed simultaneously and generation distortion cushioning effect of front apron 11 and recoil spring 13, surplus energy after will cushioning again conducts to spring chooses steel 6, spring is chosen pulley 16 extensional deformations at compressing two ends, steel 6 stressed back surplus energy is done to cushion for the second time to absorb, surplus energy after will cushioning again conducts to yielding rubber 8, yielding rubber 8 passes through compressive deformation, doing surplus energy for the third time, buffering absorbs, and actv. keeps soft contact the between vehicle body and the collision body, baffle plate guide 9 slides backward the pressure span that enters pressure shell fragment 3 by guide groove 12 under the effect of impact force, the pulley 16 that spring is chosen steel 6 two ends outwards slips into the pressure span of pressure locking plate 15 under pressure, pressure shell fragment 3, pressure locking plate 15 reduces recoil spring 13 by index pressure, spring is chosen the bounce-back speed and strength of steel 6 in order to avoid cause the bounce-back injury, 50～70 millimeters of the collision deformation amounts of whole bumper/spoiler, 2～3 seconds of reset time.
