Technical field
The present invention relates to automotive safety equipment technical field, specifically, is a kind of collision proof means for automobiles.
Background technology
Nowadays, automobile has become instrument indispensable in people's daily life, especially in recent years, the fierce growth of private car quantity, the quantity of traffic accident is also more and more, has caused a large amount of personal casualty and property damage; The personal casualty of how to prevent traffic accident to cause, also more and more receives people's concern.
More existing anti-collision device for automobile, general structure more complicated, productive costs is too high, and the effect reaching neither be clearly.
Summary of the invention
In order to overcome above technical matters, the invention provides a kind of collision proof means for automobiles.
The present invention adopts following technical scheme to realize: a kind of collision proof means for automobiles, comprise at least one energy disperser, described energy disperser comprises hydraulic actuating cylinder and piston, described piston is installed in hydraulic cylinder cavity, in described hydraulic actuating cylinder, be designed with successively from front to back hydraulic cylinder cavity and at least one release room, between the release room that described hydraulic cylinder cavity is adjacent and between adjacent release room, be respectively equipped with at least one release aperture;
In described hydraulic actuating cylinder, be designed with successively from front to back hydraulic cylinder cavity, the first release room and the second release room;
Between described hydraulic cylinder cavity and the first release room and between the first release room and the second release room, be respectively equipped with the first release aperture and the second release aperture;
The hydraulic actuating cylinder of described the second release room rear side is provided with the 3rd release aperture;
Described the first release aperture is greater than the second release aperture, and described the second release aperture is greater than the 3rd release aperture;
Described the first release aperture place is provided with earth pressure release safety plate;
Described piston is connected with piston rod, and described piston rod front end is provided with bumper coupling parts;
The contact surface place of described piston rod and hydraulic actuating cylinder is provided with oil sealing;
Described hydraulic actuating cylinder lateral wall is provided with front beam connection.
The beneficial effect that the present invention produces is, structure of the present invention is relatively simple, productive costs is lower, and be easy to install, both can when vehicle production, install, also can after automobile is sold, independently install, in actual use, actv. is avoided or has been reduced personal casualty and the property damage in traffic accident.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, be elaborated:
Fig. 1 is structural representation of the present invention
Fig. 2 is the structural representation after the present invention installs
In figure, 1, hydraulic actuating cylinder 2, piston 3, piston rod 4, hydraulic cylinder cavity 5, the first release room 6, the second release room 7, earth pressure release safety plate 8, the first release aperture 9, the second release aperture 10, the 3rd release aperture 11, bumper coupling parts 12, oil sealing 13, car front beam 14, Federal bumper 15, front beam connection
The specific embodiment
Illustrate: for the convenience of narrating, according to the mounting design rule of this device, the "up" and "down" position in accompanying drawing uses respectively " front " and " afterwards " to represent in narration.
Specifically describe embodiments of the invention below:
As shown in Figure 2, a kind of collision proof means for automobiles, comprise three energy dispersers, the concrete structure of described energy disperser as shown in Figure 1, comprise hydraulic actuating cylinder 1 and piston 2, described piston 2 is installed in hydraulic cylinder cavity 4, is designed with successively from front to back hydraulic cylinder cavity 4, the first release room 5 and the second release room 6 in described hydraulic actuating cylinder 1; Between described hydraulic cylinder cavity 4 and the first release room 5 and between the first release room 5 and the second release room 6, be respectively equipped with the first release aperture 8 and the second release aperture 9; The hydraulic actuating cylinder 1 of the second release room 6 rear sides is provided with the 3rd release aperture 10;
Wherein, when the volume of hydraulic cylinder cavity 4 interior liquid is greater than the volume sum of the first release room 5 and the second release room 6, the 3rd release aperture 10 just can play the effect of releasing liquid; When the volume of hydraulic cylinder cavity 4 interior liquid is less than or equal to the volume sum of the first release room 5 and the second release room 6, the effect of the 3rd release aperture 10 is mainly used for exhaust;
In order further to strengthen the buffering effect of energy disperser in the present invention, take following design: the first release aperture 8 is greater than the second release aperture 9, the second release aperture 9 and is greater than the 3rd release aperture 10, thereby reach the effect of classification buffering;
In addition, the first release aperture 8 places are provided with earth pressure release safety plate 7, at this, install when inoperative, prevent that the interior liquid of hydraulic cylinder cavity 4 from flowing out; Described piston rod 3 is provided with oil sealing 12 with the contact surface place of hydraulic actuating cylinder 1, for the sealing of hydraulic cylinder cavity 4, prevents from revealing;
Mounting means of the present invention is: the piston 2 of energy disperser is connected with piston rod 3, and the bumper coupling parts 11 being provided with by piston rod 3 front ends is fixedly attached to Federal bumper 14; And by hydraulic actuating cylinder 1 lateral wall, be provided with front beam connection 15 and be fixedly attached to car front beam 13.
Principle of work of the present invention is: when automobile is collided, three energy dispersers of collision proof means for automobiles design, be subject to extraneous impact, piston rod 3 pistons sharply shrink, at this moment the interior liquid of hydraulic cylinder cavity 4 is subject to impulsive force, hydraulic cylinder cavity 4 internal pressures increase, volume diminishes, earth pressure release safety plate 7 is opened, because the first release aperture 8 is greater than the second and the 3rd release aperture, liquid moment enters the first release room 5, play moment buffer action, when liquid enters after the first release room 5, by the second release aperture 9, enter the second release room 6, because the second release aperture 9 is less than the first release aperture 8, institute is so that pressure obtains again buffer release, when liquid enters after the second release room 6, because the 3rd release aperture 10 is less than the first and second release aperture, institute is so that impact pressure obtains again slow buffer release, make automobile and personal safety obtain good protective effect.
The present invention is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present invention, and every have identical or close technical scheme with the present invention, within all falling into protection scope of the present invention.
The technology that the present invention does not describe in detail, shape, structure are partly known technology.
