Abstract
The utility model discloses a shockproof buffer and automatic brake device for collision of motor vehicles, which is provided with four oil buffers. During a vehicle collision, the oil buffer is impacted by external force. Because the diameter of the oil hole of the oil buffer is invariable, the larger the collision force is, the stronger the shockproof buffer action is. In the meanwhile, the oil pressure generated by the collision force in the oil chamber jacks up the small rod in the oil hole, the travel switch is pushed, the electromagnetic valve is switched on for controlling the brake, and then the motor vehicle automatically brakes.
Description
The utility model relates to a kind of power actuated vehicle when collision of being used for, and in time plays shockproof cushioning and self-stopping device.
Along with the develop rapidly in hightech epoch, equipment, the performance of power actuated vehicle are more perfect, and the speed of a motor vehicle is faster, and vehicle number is increasing, and thing followed traffic accident, accident are also increasing progressively.The bumper/spoiler that present vehicle is adopted is a kind of very stiff and demanding solid structure, does not have the performance of shockproof cushioning.Therefore, during collision happens, the destructive that percussion power is produced is very big.
The purpose of this utility model is that a kind of power actuated vehicle shockproof cushioning and self-stopping fender guard will be provided.
The purpose of this utility model is achieved in that before the bumper/spoiler of vehicle installs oleo gear, and the oil-through hole diameter in the oleo gear is a unmodified, and the mistake oil mass of oil-through hole is fixed in the unit time.During collision happens, impact is big more, and the shockproof cushioning effect of being played is strong more.Meanwhile, impinge upon the little bar in the oil pressure jack-up oil hole that produces in the oil pocket, promote travel switch, connect electromagnetic valve control brake, the vehicle self-actuating brake.
The utility model is applicable to various power actuated vehicles, and embodiment will be explained as follows in conjunction with drawing:
Fig. 1 is a brake control system
Fig. 2 is the cutaway view of oleo gear
Fig. 3 is the installation site figure of oleo gear
1, brake actuator 2, electromagnetic valve 3, high-voltage power supply
4, travel switch 5, little bar 6, oil-through hole
Embodiment: as shown in Figure 3, four oleo gears are installed respectively on the front and back bumper/spoiler of vehicle, the piston rod in the oleo gear is connected on the bumper/spoiler.When collision happens, as shown in Figure 2, impact sees through the piston rod that is connected on the bumper/spoiler and acts on oil pocket, squeeze fluid, make fluid, fix owing to flow through the mistake oil mass of oil-through hole in the unit time to another oil pocket circulation, so impact is big more, the shockproof cushioning effect is strong more.
As shown in Figure 1 and Figure 2, when impact saw through piston rod, the oil pocket internal pressure strengthened, and the little bar in the oil pressure jack-up oil hole promotes travel switch, connected electromagnetic valve control brake, the vehicle self-actuating brake.
After impact disappeared, spring promoted piston rod and automatically resets, and as shown in Figure 2, the oil pocket internal pressure reduces, and the little bar in the oil hole hangs down automatically, and travel switch resets, and disconnects electromagnetic valve, and this device is in the state of reworking.
Two oleo gears before being installed on insurance and the rear bumper respectively are one group, and every group travel switch is in parallel, as shown in Figure 3.During collision happens, no matter bump that side at bumper/spoiler, travel switch all moves.The vehicle driver can select self-actuating brake or non-automatic brake according to the running state or the halted state of vehicle.
Following four kinds of states:
1, two cars are met mutually and are travelled, and two cars are selected self-actuating brake simultaneously.Two car self-actuating brakes during bump.
2, two cars are met mutually, and a car travels, and a car stops.The car that travels is selected self-actuating brake, stops car and selects non-automatic brake.During bump, the car self-actuating brake of travelling.Stopping the car back that is impacted moves after automatically according to inertia.
3, two cars are equidirectional travels, and front truck is selected non-automatic brake, and back car is selected self-actuating brake.When the car at high speed bump front truck of back, front truck moves ahead according to inertia, back car self-actuating brake.
4, the equidirectional car of two cars travels, and a car stops.The car that travels is selected self-actuating brake, stops car and selects non-automatic brake.The car self-actuating brake of travelling during bump stops car and moves after according to inertia.
The soft protection mode that the utility model device is adopted is more effective concerning the rigid protection mode that bumper/spoiler was confronted the tough with toughnees in the past, can cushion the exterior direct percussion power of decay greatly.
Claims (1)
- When being used for the power actuated vehicle collision, in time play the device of shockproof cushioning and self-actuating brake effect, the brake system that comprises the oleo gear that links to each other with vehicle bumper and controlled by travel switch, feature of the present utility model is: be drilled with oil-through hole 6 on the piston rod of oleo gear, be provided with the little bar 5 that is subjected to oil pressure control in the oil hole, little bar 5 promotes brake travel switch 4.
