Abstract

The utility model discloses a hydraulic damper for automobiles, which mainly comprises a hydraulic post, a steel jacket, an oil pump, an oil jetting chamber, an oil storage chamber, a spring pin, etc. The utility model uses a hydraulic pin to extrude the liquid oil in the oil jetting chamber to cause the pin to downwards move, causing the hydraulic oil to jet into the oil storage chamber in a high speed through flow jetting gaps. Thus the kinetic energy generated by object collision can be converted into the kinetic energy jetted by the liquid in the high speed to achieve the effect of relieving the impact force of the objects. The utility model has the advantages of simple structure and good buffering effect, and provides the ideal hydraulic damper for the automobiles.

Description

The automobile hydraulic energy disperser

The utility model relates to a kind of automobile collision protection device, particularly a kind of automobile hydraulic energy disperser.

The automobile collision accident that often meets accident in the process of moving, and most of automobile mainly is to protect by the elasticity of vehicle head front bumper and the steel plate of headstock own, but effect is bad, particularly often causes car crash when collision is serious.Use the ultrasonic stopping device of a kind of system controlled by computer on some luxury cars abroad, mainly be by super sonic identification the place ahead obstacle distance, when automobile and obstacle distance near excessively, then this system can carry out emergency brake automatically, thereby reach the purpose of anticollision, but this systems technology complexity, involve great expense, the reliability instability, thereby on general-utility car, be difficult to apply.

The purpose of this utility model is exactly the interaction force in the time of will providing a kind of buffer action of utilizing compression hydraulic oil and hydraulic pressure oil injection to slow down auto against to general-utility car, and automobile hydraulic energy disperser simple in structure.

The utility model is done in such a way that the automobile hydraulic energy disperser is installed in the automobile headstock, and its baffle plate is fixed on the nerf bar, base plate is fixed on the interior car sedan-chair of headstock.It mainly comprises hydraulic column, steel bushing, oil spout chamber, oil cabinet, oil pump, spring embolus, baffle plate, parts such as base plate, supporting seat.When automobile bumps, impact force acts on baffle plate, when being delivered to the hydraulic column of energy disperser again, the indoor liquid oils of hydraulic column extruding oil spout, the pressure that liquid oils acts on the spring embolus increases, and the spring embolus is moved down and forms the gap, and hydraulic oil enters oil cabinet by jet flow gap high speed jet, make the kinetic energy of object collision be converted into the kinetic energy of liquid at high speed ejection, thereby reach the effect of alleviating the object impulsive contact force.When impact force reduces or disappears, then spring is pushing away on the embolus again and is moving, and the jet flow gap is progressively reduced until closure.Utilize oil pump, liquid oils is recycled.The utility model is simple in structure, good buffer effect, and hydraulic oil recycles, and its appearance provides a kind of desirable automobile hydraulic energy disperser for people.

Below in conjunction with accompanying drawing most preferred embodiment is described:

Accompanying drawing 1 is the utility model structural representation.

With reference to accompanying drawing 1, top in the steel bushing of automobile hydraulic energy disperser [3] is that a cylindrical cavity is as oil spout chamber [5], the bottom is that a funnelform cavity is oil cabinet [7], between oil spout chamber [5] and oil cabinet [7], one circular oil nozzle [4] is arranged, steel bushing [3] is fixed on the supporting seat [15], the hydraulic column of steel [2] is equipped with oblong metal baffle [1] for cylinder one end top, the bottom becomes running-fit to be inserted in from the upper inlet of steel bushing [3], metal embolus [6] is enclosed within a metal round rod [9] upper end, spring [8] is enclosed within on the round bar [9], the top of forming spring hitch sub-spring embolus penetrates in the oil cabinet [7], make embolus [6] face oil nozzle [4], supporting seat [15] and rectangular metal base plate [13] are passed in the bottom of the metal round rod of spring embolus [9], enter a long tubular conduit [12], be enclosed within the spring [8] on the round bar [9], its end heads on embolus [6], the other end heads on metal base plate [13], supporting seat [15] is fixed on the base plate [13], oil pump [14] also is fixed on the base plate [13], with transport pipe [11] oil pump [14] and oil spout chamber [5] are communicated with, oil pump [14] are communicated with oil cabinet [7] with oil return pipe [10].
