Abstract

The utility model relates to an energy absorber for vehicle collision, which is composed of more than two energy absorbing devices, more than one oil storing box and oil pipes. A hollow piston with a rod is respectively arranged in the energy absorbing devices. A chamber is divided into a front chamber and a rear chamber by the piston. A hollow oil needle is arranged in the rear chamber; a plurality of oil holes are arranged in the hollow oil needle. Oil liquid is arranged in the energy absorbing devices; a piston and a spring are arranged in the oil box. The utility model has large stress intensity, and is capable of effectively consuming impact energy and furthest decreasing vehicle and personnel damage when the vehicles suffer intense impact.

Description

The auto against energy dissipator

The utility model relates to a kind of auto against energy dissipator.

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.Cause damage and personnel's injury in order to reduce automobile because of collision, self-propelled vehicle generally all is equipped with shock absorber, as bumper/spoiler, air bag etc.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.Therefore, people wish that urgently a kind of auto-safety mechanism can be arranged, and when the collision happens accident, rider and vehicle can both obtain real safety.

The purpose of this utility model is to provide a kind of auto against energy dissipator, and when automobile was subjected to clashing into strongly, 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 to realize by following technical scheme: the utility model auto against energy dissipator is by two above

sinkers

3,13, one with top tank 10 and oil pipe 8,9 compositions, be respectively equipped with hollow piston with

rod

2,12 in the

sinker

3,13, the sinker chamber is divided into

front chamber

4,14 and

rear chamber

7,17,

hollow spindle

6,16 wherein is housed respectively in the rear chamber, a plurality of

oilholes

5,15 are arranged on the hollow spindle; One end of oil pipe 8 is communicated with the rear chamber 7 of sinker 3, and the other end is communicated with the front chamber 14 of sinker 13, and is communicated with fuel tank 10; One end of oil pipe 9 is communicated with the rear chamber 17 of sinker 13, and the other end is communicated with the front chamber 4 of sinker 3; In the

sinker

3,13 fluid is housed; Piston 18 is housed in the fuel tank 10, spring or pressurized air are housed in the fuel tank lower chambers.

Advantage of the present utility model is: be subjected to force intensity big, consumed energy is fast, when automobile is subjected to clashing into strongly, can consume Impact energy rapidly, and vehicle is effectively cushioned, and reduces 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 embodiment.

Among the utility model embodiment shown in the drawings, two

sinkers

3,13 of installing on the automobile front beam 1, and be provided with two fuel tanks 10,11; The end of the hollow piston with

rod

2,12 in the

sinker

3,13 is connected with bumper/spoiler 1; Hollow piston with rod 2 is divided into front chamber 4 and rear chamber 7 with the chamber of sinker 3, is equiped with hollow spindle 6 in this rear chamber, and a plurality of oilholes 5 are arranged on the hollow spindle; Hollow piston with rod 12 is divided into front chamber 14 and rear chamber 17 with the chamber in the sinker 13, is equiped with hollow spindle 15 in this rear chamber, and a plurality of oilholes 15 are arranged on the hollow spindle; Oil pipe 8 is communicated with the rear chamber 7 of sinker 3 with the front chamber 14 of sinker 13, and is communicated with fuel tank 10; Oil pipe 9 is communicated with the rear chamber 17 of sinker 13 with the front chamber 4 of sinker 3, and is communicated with fuel tank 11; Fluid is housed in the sinker; Piston 18 is housed in the fuel tank, installs spring in the lower chambers of fuel tank.

During use, the front end of the utility model auto against energy dissipator is connected with Federal bumper, the rear end is connected with automotive frame.Sinker 3,13 is installed on the automotive front end bumper/spoiler 1.When automobile is subjected to strong collision, Federal bumper will clash into kinetic energy and pass to hollow piston with

rod

2,12 in the

sinker

3,13, promote to move behind the hollow piston with

rod

2,12, fluid flow at high speed in the compressing chamber, force fluid in the

rear chamber

7,17

oilhole

5,15 and oil pipe 8,9

front chamber

14,4 that enters

sinker

13,3 respectively on

hollow spindle

6,16, surplus oil liquid enters fuel tank 10,11, promotes piston 18 and moves.Because fluid high velocity stream oil-through hole, make bump kinetic energy change heat energy into and consume, flow into fluid in the fuel tank simultaneously and further make bump kinetic energy change thermal energy consumption into to fall, play buffer action, guarantee automobile and personnel's safety.After bump kinetic energy disappeared, the spring in the fuel tank 10,11 promoted piston 18, made fluid enter the

rear chamber

7,17 of sinker, promoted piston with

rod

2,12 and resetted.

At least the purpose of installing two sinkers is in order to coordinate impact, when one side of automobile was collided, bumper/spoiler passed on one side and moves behind the piston with rod, and the fluid in the compressing chamber enters the upper chamber of another sinker by oil pipe, promote to move behind another piston with rod, thereby play coordinative role.

Also can pressurized air replace spring, the effect that can play buffering equally and reset in fuel tank 10,11 lower chambers.

If only install a fuel tank 10, then the volume of sinker 3 should be greater than sinker 13.

According to the vehicle difference, can increase the quantity of sinker, improve buffering effect.

The utility model auto against energy dissipator also can be installed in automobile tail, prevents the generation of rear-end collision.
