Abstract

The utility model discloses a vehicle impact buffer device, which comprises an impact plate, a guide post and a compression plate, wherein at least four groups of integrally sheathed an inner spring, a middle spring and an outer spring are arranged between the impact plate and the compression plate, while the springs are mounted on a spring positioning shaft fixed at the inner face of the impact plate, the outer face of the impact plate is provided with a buffer rubber. Via the buffer function of the springs, the utility model can absorb much impact energy in impact to reduce impact force most and reduce hurt on user and vehicle, with simple structure and reliable property.

Description

A kind of buffer device for collision of automobile

Technical field

The utility model relates to a kind of automobile safety protector, relates to a kind of buffer device for collision of automobile specifically.

Background technology

In today of social develop rapidly, automobile becomes the main tool of people's traffic, transportation already, and the quantity of automobile is in continuous increase, and traffic accident is also constantly risen, and automobile is collided and occupied very big ratio.The device of automatic buffer collision at present generally is to increase the bumper/spoiler of being made by thin-wall stainless steel or thin-walled " U " shape channel-section steel reach car before car after, connect for rigidity between bumper/spoiler and the automobile, when automobile bumps, be out of shape the impact force of slowing down automobile by the stainless steel tube or the channel-section steel generation of contact at first.So the shortcoming of this kind device connects in rigidity, so that the collision that its produces slows down power is very little, make that the suffered impulsive force of automobile is big, therefore personnel and harm that vehicle caused are also increased.

The utility model content

At existing problem in the prior art, the utility model provides a kind of can slow down the buffer device for collision of automobile of impact force greatly when automobile bumps.

The utility model is achieved through the following technical solutions: a kind of buffer device for collision of automobile, comprise impingement plate, guide pillar and keep plate, described impingement plate is provided with at least four groups and the inner spring that is sleeved on, middle springs and outer spring between keep plate, described three kinds of springs are installed on the spring fix shaft that is fixed in the impingement plate medial surface; On the lateral surface of impingement plate, yielding rubber is set.

This kind energy disperser because the buffer action of spring can absorb most impact energy when automobile bumps, is reduced to the impact force of automobile minimum, really plays buffer action, reduces greatly personnel and harm that vehicle caused.

Description of drawings

Fig. 1 is the structural representation of the utility model buffer device for collision of automobile;

Fig. 2 is a B-B cutaway view among Fig. 1.

Among the figure: 1. yielding rubber, 2. impingement plate, 3. guide pillar, 4. keep plate, 5. adjustment nut, 6. jam nut, 7. inner spring, 8. middle springs, 9. outer spring, 10. spring fix shaft, 11. guide pillar holes, 12. screws, 13. nuts, 14. bumper/spoilers.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing and specific embodiment:

By Fig. 1, be fixed with two guide pillars 3 on the impingement plate 2, also be fixed with the spring fix shaft 10 more than four, all be respectively installed with inner spring 7, middle springs 8 and outer spring 9 on each spring fix shaft 10,4, two guide pillars 3 of keep plate that the other end of pocketed springs is provided with one two broken belt and has guide pillar hole 11 pass adjustment nut 5 that guide pillar hole 11 usefulness are located at its end and jam nut 6 respectively with its spacing outside at keep plate 4.Keep plate 4 and impingement plate 2 clamp pocketed springs, and the lateral surface of impingement plate 2 is fixed with yielding rubber 1.

By Fig. 2, inner spring 7, middle springs 8 and outer spring 9 are installed on the spring fix shaft 10 successively from inside to outside.Also an outer spring 9 can be only adorned on the spring fix shaft 10, perhaps, outer spring 9 and middle springs 8 can also be only adorned.

During installation, the termination of guide pillar 3 is injected in the hole in advance prefabricated on the Federal bumper 14, keep plate 4 is fixed on the bumper/spoiler 14 of automobile with screw 12, nut 13.

When automobile bumps, at first contact yielding rubber 1, produce for the first time and cushion, simultaneously, pocketed springs is compressed, and absorbs impact energy, produces buffering for the second time, thereby reaches the buffer action of expection when colliding.

Claims

1. buffer device for collision of automobile, it is characterized in that, comprise impingement plate, guide pillar and keep plate, described impingement plate is provided with at least four groups and the inner spring that is sleeved on, middle springs and outer spring between keep plate, described three kinds of springs are installed on the spring fix shaft that is fixed in described impingement plate medial surface; On the lateral surface of described impingement plate yielding rubber is set.
