Description

Anticollision of motor vehicles hits shock absorber

Technical field

The utility model relates to the anticollision shock absorber that a kind of power actuated vehicle prevented or alleviated the accidental impact loss, be specifically related to a kind of shock absorber that utilizes the momentum change amount to reduce to clash into momentum, to prevent or to reduce the vehicle that produces because of the power actuated vehicle accidental impact and lose and personal casualty.

Background technology

The power actuated vehicle of existing market supply, its front end only designs a fixing bumper/spoiler, during accidental impact whole kinetic energy of vehicle directly with the form of momentum through the bumper/spoiler momentary action on knocked object, vehicle and knocked object produce big application force simultaneously, cause the damage or the plastic deformation that bump against part; When serious, also can injure driver and crew; Particularly resembling utility van, minibus and carryall one class the place ahead does not have the vehicle of vehicle body outshot, just directly hurts driver and crew easily in case collide.

The utility model content

(1) technical matters that will solve

The purpose of this utility model provides a kind of anticollision of motor vehicles and hits shock absorber, thereby can avoid or degree of tortuosity when alleviating Vehicular impact and personnel's extent of injury, improves economy and safety that vehicle uses.

(2) technical scheme

Anticollision of motor vehicles of the present utility model hits shock absorber, comprise several rubber blocks, bow beam, cushion rubber, flat-topped ridge, piston apparatus, latching system, several rubber blocks are fixed on the bow beam, bow beam is connected with flat-topped ridge, piston apparatus and is connected with an end of piston apparatus, the other end of piston apparatus is connected with the self-propelled vehicle front end, cushion rubber is contained between flat-topped ridge and the bow beam, and latching system is between bow beam and self-propelled vehicle front end.

Wherein, described piston apparatus comprises piston, protection cylinder, piston rod, piston barrel, liquid, and wherein, piston is in piston barrel, and piston rod links to each other with piston, and a piston rod part is in piston barrel, and another part is in protection cylinder, and liquid is positioned at piston barrel.

Wherein, described latching system comprises snap close, snap close seat, electronic reset attachment, and wherein, snap close is fixed on the bow beam, and the snap close seat is fixed on the self-propelled vehicle front end, and electronic reset attachment is installed in the self-propelled vehicle front end.

Wherein, it is to be connected with self-propelled vehicle crossbeam geocoded activity by bolt by piston barrel that described piston apparatus is connected with self-propelled vehicle, and protection cylinder is connected with self-propelled vehicle front end oriented movable.

Wherein, described several rubber blocks are one or more circles or rectangle, and are fixed on the bow beam.

(3) beneficial effect

The utility model advantage is: 1 because the buffer action of rubber block, bow beam, piston apparatus when self-propelled vehicle and knocked object bump against, can significantly alleviate vehicle loss and personnel's extent of injury; 2 simple in structure, cost is lower, processing realizes easily, and is installed in the characteristics that self-propelled vehicle the place ahead has good looking appearance; 3 the utility model can be when emergency brake go out before automatically, preceding go out after as with the obstacle bump, can automatically reset, its degree of automation height, functional reliability is good; Safe and applicable.

Description of drawings

Fig. 1 is a front view of the present utility model;

Fig. 2 is the birds-eye view of Fig. 1;

Fig. 3 is the left view of Fig. 1.

Among the figure: 1, rubber block, 2, piston, 3, protection cylinder, 4, piston rod, 5, cushion rubber, 6, flat-topped ridge, 7, crossbeam, 8, crossbeam, 9, electronic reset attachment, 10, bow beam, 11, snap close, 12, the snap close seat, 13, piston barrel.

The specific embodiment

Following examples are used to illustrate the utility model, but are not used for limiting protection domain of the present utility model.

As Fig. 1, Fig. 2, shown in Figure 3, a kind of anticollision of motor vehicles of the present utility model hits shock absorber and goes out part by 5 rubber blocks 1, bow beam 10, two pistons 2, two protection cylinder 3, two piston rods 4, two piston barrels 13, two cushion rubbers 5, a flat-topped ridge 6 before forming; Piston barrel 13 is connected with crossbeam 7 by bolt, the crossbeam on both sides and crossbeam 8 rivet weldings are the pedestal that one becomes shock absorber, two protection cylinder 3 are by 8 orientations of the crossbeam on the crossbeam 7, the position plate of crossbeam 8 and side goes out fulcrum partly before being again, snap close 11 and snap close seat 12 make and go out part before of the present utility model and rest on the rear position at ordinary times, automatically free during emergency brake, before go out after as with obstacle bump, can make to go out part before of the present utility model and turn back to the rear position by electronic reset attachment 13.Working process of the present utility model is: when brake driver, go out before of the present utility model and go out a segment distance before part is utilized force of inertia, contact goes out part before of the present utility model behind the obstacle and resets backward, because speed is very fast, liquid behind the utility model piston 2 can not in time flow to piston 2 fronts through annular mouth, produce a resistance, this resistance continues for some time, and has consumed a part of Impact energy; If when failing all to consume Impact energy, the utility model fwd bow beam 10 elastic deformations again can the absorption portion Impact energy, just reduced most of Impact energy of vehicle like this, has significantly alleviated vehicle loss and personnel's extent of injury; Brake torque hour, the utility model does not before go out, the utility model fwd rubber block 1 can absorb Impact energy with the elastic deformability of bow beam 10, avoid minor impact to vehicle before the damage of parts such as face and water tank.
