The anti-collision device for the automobile has the benefits as follows: the structure is relatively simple, the production cost is lower, and the mounting is easy; the device can be mounted when the automobile is produced and can also be automatically mounted after the automobile is sold; and in the actual use, casualties and property loss in a traffic accident are effectively avoided or reduced.
Description
Technical field
The present invention relates to automotive safety equipment technical field, specifically, it is a kind of collision proof means for automobiles.
Background technology
Nowadays, automobile has become as indispensable instrument in people's daily life, especially in recent years, private car
The fierce growth of quantity, the quantity of vehicle accident also gets more and more, and causes substantial amounts of casualties and property damages
Lose；The casualties how preventing vehicle accident to cause, is also increasingly paid close attention to by people.
Some anti-collision device for automobile existing, general structure is more complicated, and production cost is too high, and reach
Effect is not apparent.
Content of the invention
In order to overcome above technical problem, the invention provides a kind of collision proof means for automobiles.
The present invention adopts the following technical scheme that realization：A kind of collision proof means for automobiles, including at least one buffering
Device, described buffer includes hydraulic cylinder and piston, and described piston is installed in hydraulic cylinder cavity, in described hydraulic cylinder
It is designed with hydraulic cylinder cavity and at least one release room, the release that described hydraulic cylinder cavity is adjacent from front to back successively
It is respectively equipped with least one release aperture between room and between adjacent release room；
It is designed with hydraulic cylinder cavity, the first release room and the second release room from front to back successively in described hydraulic cylinder；
Set respectively between described hydraulic cylinder cavity and the first release room and between the first release room and the second release room
There are the first release aperture and the second release aperture；
Hydraulic cylinder on rear side of described second release room is provided with the 3rd release aperture；
Described first release aperture is more than the second release aperture, and described second release aperture is more than the 3rd release aperture；
It is provided with pressure relief fuse piece at described first release aperture；
Described piston is connected with piston rod, and described piston rod front end is provided with bumper coupling parts；
It is provided with oil sealing at described piston rod and the contact surface of hydraulic cylinder；
Described hydraulic cylinder lateral wall is provided with front beam connection.
The beneficial effect comprise that, present configuration is relatively easy, production cost is relatively low, and be easy to
Install, both can install in vehicle production it is also possible to independently install after automobile is sold, actually used
In, effectively avoid or reduce the casualties in vehicle accident and property loss.
Brief description
It is described in detail with reference to the accompanying drawings and detailed description：
Fig. 1 is present configuration schematic diagram
Fig. 2 is the structural representation after present invention installation
In figure, 1, hydraulic cylinder 2, piston 3, piston rod 4, hydraulic cylinder cavity 5, the first release room 6,
Two release rooms 7, pressure relief fuse piece 8, the first release aperture 9, the second release aperture 10, the 3rd release aperture
11st, bumper coupling parts 12, oil sealing 13, car front beam 14, bumper 15, front beam connection
Specific embodiment
Explanation：For the convenience describing, according to the mounting design rule of this device, the "up" and "down" in accompanying drawing
Position, uses " front " and " afterwards " to represent in narration respectively.
To specifically describe embodiments of the invention below：
As shown in Fig. 2 a kind of collision proof means for automobiles, including three buffers, the concrete knot of described buffer
Structure is as shown in figure 1, include hydraulic cylinder 1 and piston 2, described piston 2 is installed in hydraulic cylinder cavity 4, described
It is designed with hydraulic cylinder cavity 4, the first release room 5 and the second release room 6 from front to back successively in hydraulic cylinder 1；Institute
State between hydraulic cylinder cavity 4 and the first release room 5 and set respectively between the first release room 5 and the second release room 6
There are the first release aperture 8 and the second release aperture 9；The hydraulic cylinder 1 of the second release room 6 rear side is provided with the 3rd release
Hole 10；
Wherein, in hydraulic cylinder cavity 4, the volume of liquid is more than the volume of the first release room 5 and the second release room 6
During sum, the 3rd release aperture 10 just can play the effect of release liquid；The small volume of liquid in hydraulic cylinder cavity 4
In or be equal to the first release room 5 and the second release room 6 volume sum when the 3rd release aperture 10 effect master
If being used for aerofluxuss；
In order to strengthen the buffering effect of buffer in the present invention further, take following design：First release aperture 8
More than the second release aperture 9, the second release aperture 9 is more than the 3rd release aperture 10, thus reaching the effect of classification buffering；
In addition, being provided with pressure relief fuse piece 7 at the first release aperture 8, when this device is inoperative, prevent
In hydraulic cylinder cavity 4, liquid flows out；It is provided with oil sealing 12 at described piston rod 3 and the contact surface of hydraulic cylinder 1, use
In the sealing of hydraulic cylinder cavity 4, prevent from revealing；
The mounting means of the present invention is：The piston 2 of buffer is connected with piston rod 3, by piston rod 3 front end
The bumper coupling parts 11 being provided with are fixedly attached to bumper 14；And set by hydraulic cylinder 1 lateral wall
Front beam connection 15 is had to be fixedly attached to car front beam 13.
The operation principle of the present invention is：When automobile is collided, three bufferings of collision proof means for automobiles design
Device, is impacted by extraneous, and piston rod 3 piston drastically shrinks, and at this moment in hydraulic cylinder cavity 4, liquid is impacted
Power, in hydraulic cylinder cavity 4, pressure increases, and volume diminishes, and pressure relief fuse piece 7 is opened, because first releases
Discharge hole 8 is more than second and the 3rd release aperture, and liquid moment enters the first release room 5, plays moment cushioning effect,
After liquid enters the first release room 5, the second release room 6 is entered by the second release aperture 9, due to the second release
Hole 9 is less than the first release aperture 8, so making pressure be released again buffering, when liquid enters the second release
Behind room 6, because the 3rd release aperture 10 is less than the first and second release aperture, so making impact pressure obtain again
To slow release buffering, automobile and personal safety is made to obtain good protective effect.
The present invention is not limited to above-mentioned embodiment, and anyone should learn the structure made under the enlightenment of the present invention
Change, every have same or like technical scheme with the present invention, each falls within protection scope of the present invention.
Technology that the present invention does not describe in detail, shape, construction part are known technology.
