Abstract
The utility model relates to an anti-collision device for a motor vehicle, which is composed of more than two coordination and energy dissipation devices, an oil pipe and a return device. Oil liquid and cross pistons are arranged in the coordination and energy dissipation devices, one end of each of cross piston is a hollow piston rod on which a plurality of oil through holes are arranged, the upper and the lower oil chambers of the two coordination and energy dissipation devices are respectively communicated by the oil pipe, and the rear ends of the coordination and energy dissipation devices are respectively connected with the return device. The stress strength of the utility model is large. When the motor vehicle is impacted intensely, impact energy can be effectively consumed, and the injury of the motor vehicle and a personnel's injury can be furthest decreased.
Description
The utility model relates to a kind of automobile collision preventing device.
Self-propelled vehicle crashes in the process of moving sometimes, and vehicle is sustained damage, and returns the personnel's of riding life security and brings threat.Damage because of collision in order to reduce automobile, self-propelled vehicle generally all is equipped with shock absorber.But existing shock absorber can only play buffer action under certain condition, and can't make automobile reduce automobile and personnel's injury to greatest extent when being subjected to clashing into strongly.
The purpose of this utility model is to provide a kind of automobile collision preventing device, and when automobile was subjected to strong collision, the bump kinetic energy that this device can transmit Federal bumper changed thermal energy consumption into and falls, and reduced the damage of automobile and personnel's injures and deaths to greatest extent.
The purpose of this utility model is achieved in that the utility model automobile collision preventing device is by coordinating sinker 3 and 9 more than two, oil pipe 10 and 11, two above returning devices 5 are formed, coordinate in the sinker fluid and cross piston to be housed, cross piston 2 in the coordination sinker 3 should be coordinated sinker and be divided into upper chamber 1 and lower oil chamber 4, cross piston 7 in the coordination sinker 9 should be coordinated sinker and be divided into upper chamber 6 and lower oil chamber 8, cross piston 2 and an end of 7 are respectively the hollow piston bar, this piston rod is provided with a plurality of oil throughs 12, the upper chamber 1 that oil pipe 10 will be coordinated sinker 3 is communicated with the hollow piston bar of cross piston 7 in the coordination sinker 9, the hollow piston bar that oil pipe 11 will be coordinated cross piston 2 in the sinker 3 is communicated with the upper chamber 6 of coordinating sinker 9, and two coordinate the cross piston 2 in the sinker, 7 rear end is connected with two returning devices 5 respectively.
The automobile collision preventing device is installed on the automobile front beam, when automobile is collided, the kinetic energy of Federal bumper transmission promotes cross piston 2,7 and moves, fluid high velocity stream in the compressing grease chamber 4,8 is crossed the hollow piston bar that oil through 12 enters cross piston 2 and 7, enter grease chamber 6,1 respectively through oil pipe 10,11 again, move behind the cross piston 2,7, bump kinetic energy becomes heat energy and consumes.After bump kinetic energy disappears, cross piston reset under the effect of pull back spring 5.
Advantage of the present utility model is: be subjected to force intensity big, when automobile is subjected to clashing into strongly, can consume Impact energy effectively, reduce automobile and personnel injury to greatest extent.
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is the structural representation of the utility model automobile collision preventing device embodiment.
Among the figure, coordinate sinker 3,9 fluid and cross piston 2 and 7 are housed respectively, one end of cross piston is respectively the hollow piston bar, on several oil throughs 12 are arranged, the upper chamber 1 that oil pipe 10 will be coordinated sinker 3 is communicated with hollow piston 7 in coordinating sinker 9, the upper chamber 6 that oil pipe 11 will be coordinated sinker 9 is communicated with hollow piston 2 in coordinating sinker 3, and two returning devices 5 are installed in the rear ends of the cross piston 2,7 in the two coordination sinkers.Returning device 5 in the present embodiment is a pull back spring.
During use, will coordinate sinker 3,9 and be installed on the automobile front beam 13.When automobile is collided, move behind the cross piston 2,7, the fluid in the compressing grease chamber 4,8 enters cross piston 2,7, enters grease chamber 6,1 by oil pipe 10,11, makes bump kinetic energy change thermal energy consumption into and falls, and guarantees automobile and personnel's safety.
After energy disappeared, pull back spring 5 resetted cross piston 2,7.
According to the difference of vehicle, can increase the number of coordinating sinker.
The utility model automobile collision preventing device also can be installed in automobile tail, prevents the generation of rear-end collision.
