Abstract
The utility model discloses a buffer for automobile collide, comprising a hydraulic cylinder. The both ends of the hydraulic cylinder are respectively mounted on an automobile chassis and a bumper. The piston of the hydraulic cylinder is provided with oil drainage holes and oil return holes which can only circulate along the one-way direction, and the outside of the cylinder is sheathed with a pressure spring. When the automobile takes place the crash, the pressure spring positioned outside of the cylinder and the oil and the air in the cylinder respectively consumes the impact energy. Therefore, when the automobile takes place the crash, the impact force can be obviously reduced.
Description
The utility model relates to a kind of damping device that reduces the car crash impact force.
Damage headstock when avoiding automobile to bump, various automobiles all forwardly are equipped with bumper.Because bumper and automobile chassis are for being rigidly connected, the impact force when bumping still acts on the automobile, threatens the safety of driver and conductor or goods.
The purpose of the utility model is to provide a kind of buffer device for collision, the impact force when reducing car crash.
The utility model has oil hydraulic cylinder, and respectively there is connecting ring the end of its cylinder barrel and piston rod, is respectively applied for to connect automobile chassis and bumper.The one circle oil drainage hole and a circle spill port of annular array are arranged on the piston, and each hole is through hole.Piston one end has the spring compression baffle plate to seal oil drainage hole, and the piston the other end has the spring compression baffle plate to seal spill port, but makes the only one-way flow of oil drainage hole and spill port.Outside the cylinder barrel, be with a stage clip, its two ends prop up bumper and automobile chassis respectively.
Described buffer is contained on the automobile, and normal state is that piston rod stretches out, and piston is in the outer end in the cylinder barrel.Inner cavity of cylinder injects hydraulic oil, but does not fill with, and makes the existing oil of inner cavity of cylinder that air also be arranged.When bumping, the outer stage clip of cylinder barrel at first is compressed, and piston begins to move, and the air of inner chamber is compressed again, and when air pressure during greater than the spring force of oil drainage hole baffle plate, oil drainage hole is open-minded.Air stream is to the opposite side of piston, and piston continues to move, and makes hydraulic oil flow to the piston opposite side by oil drainage hole.The air of stage clip, inner chamber successively is compressed accumulation of energy in knockout process, and air and hydraulic oil flow are through oil drainage hole, and the flow resistance power consumption with the impact kinetic energy conversion, thereby has been alleviated the influence of impact force to people, goods in vehicle structure and the car.After collision finished, the tension force of pressured spring resetted this device.It is safer than the mode that is rigidly connected of routine to adopt described buffer to connect bumper, and causality loss is littler.
Accompanying drawing is the sectional view of described buffer.
An automobile needs to be contained in the bumper two ends respectively with the described buffer of two covers, and the connecting ring 1 of cylinder barrel 4 and piston rod 3 ends links to each other with the chassis with bumper respectively.Outside the cylinder barrel 4, be with stage clip 2, its two ends prop up bumper and chassis.The spill port 11 that has a oil drainage hole 10 that a circle arranges and a circle to arrange on the piston 7 in the cylinder barrel, piston 7 one ends have spring 5 to compress baffle plate 6 to seal oil drainage hole 10, and the spring 8 of piston 7 the other ends compresses baffle plate 9.Seal spill port 11, inner chamber injects hydraulic oil, but does not fill with.
