Abstract

The utility model relates to a composite type buffering bumper for vehicles. Rubber spongy gas bag bars are stuck on a metallic framework which is connected with a synthetic buffering spring and a hydraulic vibration damper to be suspended at the front end of a girder and then to be connected with a cross beam which is fixed with the vehicle girder. At the time of stress, the impact force can be absorbed by the composite type buffering bumper in a multistage way. In the vehicle, each connecting position is not loosened, each wheel track doesn't shift. The composite type buffering bumper whose both ends are provided with photosensitive warning signs forms an oblong semicircle, and is especially provided with an impact automatic brake device. The gas bag bars receive the force of a transferring bar and a tension spring to push the hand spike of a master pump which works, and the brake acts. The speed can be automatically decreased and the impact force can be reduced. The utility model has the advantages of beautiful and simple structure and conspicuous safety effect.

Description

Combined type buffering automobile bumper/spoiler

The utility model relates to a kind of Federal bumper, specifically also is a kind of composite buffering Federal bumper.It is widely used in various cars, passenger vehicle, lorry, when in the driving transportation, bumping, can the powerful impact force of multistage absorption, especially when can't the crash-avoidance accident taking place voluntarily moment damping, shock-absorbing, slow down impulsive force, can effectively alleviate economic loss and driver and conductor's injures and deaths.

At present, the original bumper structure of known automobile is to be made by metal sheet or plastics, connect on the automobile front cross rail with screw, when automobile bumps, very stiff and demanding parts sensitive for damages, the impulsive force in the time of can't absorbing collision, safety effect is little, reason is that the impact thick stick that is not insured absorbs, and does not have cushioning effect.

According to both at home and abroad, relevant bibliographical information, etesian in the world car accident is increasing, and statistical probability accounts for 82%, car crash, suffers heavy losses, and West Germany motor insurance company is necessary for slight car accident every year and pays nearly 5,000,000,000 mark's Amount Insureds; American-European countries has taked relevant reinforced safety thick stick and rules measure, solves the collision problem; China insurance department announces that general area is annual because of traffic collision repair expense expenditure reaches more than 600 ten thousand Renminbi, and the national stack up word that counts is quite surprising.Therefore, the countries in the world researchist has done to probe boldly for solving auto against, it is reported that Japan installs rubber block additional or load onto liquid damper on Federal bumper, but effect is undesirable.

The purpose of this utility model is exactly when providing a kind of automobile to bump in order to overcome weak point of the prior art, can moment pass through repeatedly damping, absorbs the combined type buffering automobile bumper/spoiler of powerful impact force.

The purpose of this utility model is achieved in that before automobile crossbeam foremost, the position of former bumper/spoiler, installation one has the spongy gas bag thick stick of neoprene of luminous sign, and be bonded on the purpose made steel plate, have at least two water bumper front ends to be fixed on the steel plate of the spongy gas bag thick stick of neoprene with rivet, the rear end of water bumper is fixed on the supporting crossbearer, there is the synthetic spring front end of a plurality of engineering plastics metals to be fixed on equally on the special steel plate, the rear end joins with the supporting crossbearer, transmitting bar front end and special steel plate joins, rear end and master brake cylinder push rod join, and such three subtract crash device, are to link to each other on automotive frame by the back that joins.The spongy gas bag thick stick of described neoprene is by rubber, metallic support synthetic sponge body gas bag thick stick, rectangular bar shaped, the front end of horizontal car.Described luminous sign is to be made by the sensitization lacquer of electromagnetism, photosensitive coating, is located at the midway location of the spongy gas bag of neoprene.Described water bumper is made up of oil cylinder, cylinder body, piston, is the garden barrel shape.The synthetic spring of described engineering plastics metal is synthetic by medal spring and engineering plastics.

The utility model has been compared following good effect with prior art, first this combined type buffering automobile bumper/spoiler is when automobile bumps, at first contact with the spongy gas bag thick stick of neoprene, because it is used both hard and soft tactics, stand in the breach and cut down the part impulsive force, while engineering plastics metal spring and water bumper, brake pump produces cushion effect, cuts down impulsive force and impact force, the brake that such moment links up and finishes, the process of multistage counteracting impact, thereby when reaching auto against, cut down the effect of shock-absorbing.The second, in view of each junction of above-mentioned advantage not because of bump becomes flexible, weld crack not, attachment point is not shifted, support, intermediate transverse girder are indeformable, non-warping, wheelbase is not shifted, thereby has guaranteed that each component part is not damaged.Three, owing to adopt luminous sign; not influenced by obstacle; give signal; travel or park cars in the far the place ahead of just finding; to step up vigilance, particularly overcast and rainy road is sliding, the greasy weather is more suitable, even just in case also can improve safety factor effectively after bumping; protect the extent of damage of vehicle to greatest extent, correspondingly reduce the safety of economic loss and people's lives and properties.

Below in conjunction with accompanying drawing structure of the present utility model and service condition are described in further detail.

1 is structural representation of the present utility model among the figure.

Component serial number and title among the figure:

(1) bar, (8) extension spring, (9) brake pump, (10) back neoprene sponge thick stick, (11) back luminous sign are transmitted in the spongy gas bag thick stick of neoprene, (2) luminous sign, the synthetic spring of (3) engineering plastics metal, (4) water bumper, (5) medal spring, (6) overall apparatus fulcrum, (7).

As shown in drawings, the spongy gas bag thick stick of neoprene (1) is provided with synthetic spring (3) water bumper (4) the overall apparatus fulcrum (6) of luminous sign (2) and engineering plastics metal, transmits bar (7), brake pump (9) links to each other on automotive frame by the back that joins.When the spongy gas bag thick stick of neoprene is stressed, can pass to special steel plate, absorb for the first time impact, after special steel plate is stressed, because stressed degree varies sample, water bumper is for the second time stressed, after absorbing a part of impact force, the synthetic spring of engineering plastics metal works stressed for the third time, absorbs a large amount of impact forces, such three grades of absorption power process, played cushioning effect, transmit under bar and the extension spring effect when the stressed promotion of neoprene sponge gas bag thick stick, promote total pump push rod, total pump work brake is worked.
