Abstract

The utility model relates to an anti-collision accessory for an automobile bumper. At present, the automobile bumpers comprise two types, one type of bumpers are formed by iron pipes or steel pipes, and the other type of bumpers are made of plastic. When the iron pipes or steel pipes are collided, a collided object can be damaged, a plastic material is provided with corners and edges and has rigidity, damage also can be caused by collision, and danger is caused to the two collided objects. The anti-collision accessory for the automobile bumper is characterized by being composed of a rubber collision layer, a buffer layer and a rubber bouncing layer, the rubber collision layer is located on an outer layer of the anti-collision accessory, the rubber bouncing layer is located on an inner layer of the anti-collision accessory, and the buffer layer is located between the rubber collision layer and the rubber bouncing layer. The rubber collision layer and the rubber bouncing layer are correspondingly divided into multiple sections, a plurality of bone-shaped buffer parts are evenly distributed in the buffer layer at intervals, and the end portion of the rubber collision layer and the end portion of the rubber bouncing layer are both in half crescent shapes, wherein the rubber collision layer and the rubber bouncing layer are located at the two ends of the anti-collision accessory. The anti-collision accessory for the automobile bumper can reduce impact force and friction.

Description

A kind of crashproof annex for Federal bumper

Technical field

The utility model relates to automotive safety accessory device field, especially relates to a kind of crashproof annex for Federal bumper.

Background technology

Current Federal bumper employed both at home and abroad has two kinds, and a kind of is iron pipe or steel pipe material, and another kind is plastic material.The general of iron pipe or steel pipe material is all applied on the more intense vehicle of the impulsive forces such as truck or cross-country car, apart from the space of vehicle body 10-20cm left and right, if bumped, hit thing will be damaged; The Federal bumper of plastic material is general, and what adopt is all flexible plastic, but soft plastics are made bumper/spoiler again, have edges and corners and also have hardness, and the words that occur to clash into also can cause damage, more dangerous for collision both sides.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of crashproof annex of Federal bumper that can reduce impulsive force and friction when bumping.

For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of crashproof annex for Federal bumper, its special feature is: described crashproof annex is comprised of rubber collision layer, cushion layer and rubber bounce-back layer, described rubber collision layer is positioned at the skin of crashproof annex, rubber bounce-back layer is positioned at the internal layer of crashproof annex, and cushion layer is positioned in the middle of rubber collision layer and rubber bounce-back layer; Rubber collision layer and rubber bounce-back are layer corresponding is divided into multistage, in cushion layer between every section of rubber collision layer and rubber bounce-back layer, be evenly intervally distributed with a plurality of bone shape damper elements, the end that is positioned at the rubber collision layer at its two ends and rubber bounce-back layer in described crashproof annex is half crescent shape.

Described bone shape damper element is comprised of the first rubber layer, the second rubber layer and springs of being positioned in the middle of both, and the arranged outside of described rubber bounce-back layer has suction iron plate.

Described rubber collision layer, rubber bounce-back layer, the first rubber layer and the second rubber layer are airbag structure.

Compared with prior art, the beneficial effects of the utility model are:

1. crashproof annex of the present utility model is comprised of rubber collision layer, cushion layer and rubber bounce-back layer, in cushion layer, be provided with bone shape damper element, while bumping, there is good buffering effect, and rubber has elasticity, when automobile bumps, can collision both sides' damage be dropped to minimum;

2. the internal layer of the rubber of crashproof annex bounce-back layer is provided with suction iron plate, can firmly be adjacent to Federal bumper, and convenient disassembly, can improve the safety factor of automobile.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the structural representation of bone shape damper element in the utility model.

In figure: 1. rubber collision layer, 2. inhale iron plate, 3. rubber bounce-back layer, 4. spring, 5. the first rubber layer, 6. the second rubber layer, 7. cushion layer, 8. bone shape damper element.

The specific embodiment

Below with reference to accompanying drawing, the utility model is described in detail.

As shown in Figure 1, a kind of crashproof annex for Federal bumper, this crashproof annex is comprised of rubber collision layer 1, cushion layer 7 and rubber bounce-back layer 3, rubber bounce-back layer 3 is positioned at the internal layer of rubber anti-collision part, rubber collision layer 1 is positioned at the skin of rubber anti-collision part, and when bumping contact, rubber collision layer 1 can actv. prevents friction and the scratch of two cars in hard collision; Cushion layer 7 is positioned in the middle of rubber collision layer 1 and rubber bounce-back layer 3; What rubber collision layer 1 and rubber bounce-back layer 3 were corresponding is divided into 5 sections, cushion layer 7 between every section of rubber collision layer 1 and rubber bounce-back layer 3 is interior is evenly intervally distributed with a plurality of bone shape damper elements 8, is positioned at the rubber collision layer 1 at crashproof annex two ends and the end of rubber bounce-back layer 3 is half crescent shape.

In cushion layer 7 between the rubber collision layer 1 at crashproof annex two ends and rubber bounce-back layer 3, there are 4 bone shape damper elements 8, in the cushion layer 7 between other rubber collision layers 1 and rubber bounce-back layer 3, there are 3 bone shape damper elements 8.

As shown in Figure 2, bone shape damper element 8 is comprised of the first rubber layer 5, the second rubber layer 6 and springs 4 of being positioned in the middle of both.

The arranged outside of rubber bounce-back layer 3 has the iron plate 2 of suction.

Rubber collision layer 1, rubber bounce-back layer the 3, first rubber layer 5 and the second rubber layer 6 are airbag structure.

When mounted, rubber bounce-back layer 3 is close to Federal bumper, inhale iron plate 2 and there is adsorption, can rubber anti-collision part and Federal bumper laminating is tighter, the rubber collision layer 1 of half crescent shape and rubber bounce-back layer 3 can fit tightly with it according to the natural camber of Federal bumper.

In the moment of two car collisions, rubber collision layer 1 actv. prevents friction and the scratch of two cars in hard collision, when rubber collision layer 1 is subject to the extruding of car, its elastic force can weaken the impulse force of contact-impact, and buffering passes to cushion layer 7 after falling part impulse force, in the middle of the bone shape damper element 8 of cushion layer 7, be provided with spring, buffering is fallen part impulse force again, remaining impulse force is passed to rubber bounce-back layer 3, rubber bounce-back layer 3 fits together and jointly impulse force is strikeed back with car body, impulse force is passed to cushion layer 7 and rubber collision layer 1 successively, part impulse force is cushioned again, when now impulse force is compared impact moment, reduced a lot, the maximized damage of having avoided two car collisions to cause.

The foregoing is only better embodiment of the present utility model; protection domain of the present utility model is not limited with above-mentioned embodiment; in every case the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or is changed, and all should include in the protection domain of recording in claims.
