Abstract
The present invention relates to a kind of buffer device for collision of automobile, it is made of front bumper, dsah-pot, buffering hydraulic cylinder, controller, when colliding, front bumper moves backward, and buffer barrel inner spring is compressed, after being fully compressed, signal is reached controller, controller output signal by pressure sensor, and hydraulic cylinder is started to work, oil in fuel tank enters hydraulic cylinder by valve pipe, to continue the pressure that buffering collision generates；The present invention is divided into be buffered twice, and when impact force is smaller, dsah-pot can effectively dissolve impact force, reduces damage；When impact force is larger, buffering can effectively dilute impact force twice, protect vehicle frame, reduce frame damage, and the present apparatus may be reused, to reduce maintenance cost.
Description
Technical field
The present invention relates to a kind of buffer device for collision of automobile, belong to automobile safety protector technical field.
Background technique
The current main energy absorption device of automobile in an impact is bumper, fender, hood and front longitudinal beam, so
Very big buffer protection function is played in collision, but bumper is single, when automobile collides, cannot effectively disappear
Except the huge impact force generated by collision, the accident of car crash caused by cannot preventing to the maximum extent because of traffic accident,
After moment deforms simultaneously, protection energy-absorbing function can not be further served as, accordingly, it is desirable to provide a kind of new technical solution solves
Certainly above-mentioned technical problem.
Summary of the invention
For deficiency existing for existing structure, problem to be solved safely may be used there is provided a kind of simple and reasonable for structure
It leans on, the buffer device for collision of automobile for causing damage to automobile due to collision can be effectively reduced.A kind of buffer device for collision of automobile
Including front bumper, dsah-pot, buffering hydraulic cylinder, controller, the dsah-pot is made of outer cylinder, compressed spring, constrictor,
Outer cylinder is welded on bumper, and constrictor is connected with hydraulic cylinder.
According to a kind of buffer device for collision of automobile recited above, altogether with there are three dsah-pot and three are hydraulic on bumper
Cylinder, after colliding, dsah-pot is first begin to work, and bumper moves backward, compresses buffer spring, and spring is fully compressed
Afterwards, pressure sensor is collected into signal, reaches controller, and output signal regulation hydraulic cylinder is started to work；After the completion of collision,
Compressed spring restores to the original state, and pressure becomes smaller, and sensor receives signal, and outputs signals to hydraulic cylinder, and liquid stays oil return in cylinder
Case, buffering are completed, and the present apparatus is reusable.
The beneficial effects of the present invention are: the impact force of collision is allowed to have a smooth increase process, collision is worked as a buffer,
In addition it is buffered twice because having, makes automobile in friction speed collision process, can not only reduce the both sides that collide to the maximum extent
The degree of injury of vehicle, effective protection vehicle frame improve bumper energy absorption effect, and can protect direct experience to the maximum extent
The personnel of collision.
Detailed description of the invention
The present invention will be further explained below with reference to the attached drawings:
Fig. 1 is schematic view of the mounting position of the present invention；
Fig. 2 is the structural schematic diagram of buffer unit of the invention.
In attached drawing: 1- bumper 2- dsah-pot outer cylinder 3- dsah-pot buffer spring 4- dsah-pot constrictor 5- hydraulic cylinder
6- oil pipe 7- pipe fitting 8- hydraulic valve 9- fuel tank 10- controller 11- pressure sensor.
Specific embodiment
The present invention is described further with reference to the accompanying drawing.
As shown in Figure 1 and Figure 2, a kind of buffer device for collision of automobile installation site is as shown in Figure 1, the present apparatus includes preceding insurance
Thick stick (1), dsah-pot (12), buffering hydraulic cylinder (5), controller (10), the dsah-pot (12) is by outer cylinder (2), compressed spring
(3), constrictor composition (4), outer cylinder (2) are welded on bumper (1), and constrictor (4) is connected with hydraulic cylinder (5).
According to a kind of buffer device for collision of automobile recited above, altogether with there are three dsah-pot and three are hydraulic on bumper
Cylinder, dsah-pot are welded on bumper, and after head-on crash occurs, dsah-pot (12) is first begin to work, and bumper (1) is backward
Movement is compressed buffer spring (3), and after spring (3) is fully compressed, pressure sensor (11) is collected into signal, reaches controller
(10), and output signal regulation hydraulic cylinder (5) is started to work, and fuel tank (9) interior hydraulic oil is flowed by valve (8) and oil pipe (6)
Hydraulic cylinder (5) starts to work as a buffer again；After the completion of collision, spring (3) restores to the original state, and pressure reduces, pressure sensor
(11) signal is received, and is outputed signal in hydraulic cylinder (5), liquid stays oil return box (9) by oil pipe (6) and valve (8).
Claims (4)
1. a kind of buffer device for collision of automobile, it is characterised in that: by front bumper, dsah-pot, buffering hydraulic cylinder, controller group
