Two-stage high-pressure cylinder energy disperser keep off a car before by cylinder type high-pressure cylinder, piston, connection car plate iron and piston smooth connecting rod, with car before the shelves people elastic sheet iron that plate iron flexibly connects that keeps off a car form.The plate of keeping off a car is purchased into a crushable elasticity box with shelves people plate.On the plate of keeping off a car in the elasticity box, there is a pressure to touch switch and a harder spring.There is automobile high pressure vapour commonly used to import and export a petrol jet and an electro spark shower nozzle that touches switch control by pressure at the cylinder tail end.Also there is a high pressure vapour commonly used to import and export at the cylinder front end.At the cylinder-shaped coat of keeping off a car and one softness being arranged, easily unfold between plate and cylinder front end, overcoat will stretch out the outer smooth connecting rod of cylinder and seal.When start, the driver will use high pressure vapour always with hand switch and import and export the input cylinder from tail end, piston, the plate of keeping off a car, retaining people plate can be released 40-80 centimetre (deciding according to vehicle) forward and backward.Though vehicle body is increased, does not influence the operation of automobile temporarily.When automobile does not start, the driver will use high pressure vapour always with hand switch and import and export input from the cylinder front end, piston can be depressed into the cylinder tail end, make keep off a car plate and retaining people plate before the car and behind the car near automotive front end and rear end.Bodywork length increase this moment seldom increases the parking space of automobile hardly.So can solve first technical matters.
When soft collision took place the pedestrian on automobile and road, because the impulse force that retaining people plate is subjected to is less, it is also less that the spring on the plate of keeping off a car is compressed the deformation that is produced, and pressure is touched switch and can be switched on.Has only high pressure vapour commonly used in the cylinder.In the soft collision process, retaining people plate, the plate of keeping off a car, piston will be pushed back 40-80 centimetre.This distance that is pushed back is exactly a buffer distance.Like this big buffer distance and buffering time can significantly reduce automobile completely and satisfy the need and go up pedestrian's maximum impact force, thereby significantly reduce the pedestrian is collided to death or severely injured danger.At automobile and automobile, building, when hard the collision takes place in trees etc., because the impulse force that retaining people plate is subjected to is very big, it is also very big that the spring on the plate of keeping off a car is compressed the deformation that is produced, pressure is touched switch and can be switched on surely, control a relay, connect a time-delay switch, the spraying nipple control circuit is connected, the spraying nipple of afterbody will eject gasoline, then through one blink the electro spark control circuit be switched on, the electro spark shower nozzle will spray electro spark, and the gasoline igniting blast with ejection produces special high pressure vapour, increased pressure greatly to piston, prolonged surge time, significantly reduced the suffered maximum impact force of automobile, significantly reduced automobile itself and driver and passenger may be subjected to the danger of major injury.Thereby solved second technical matters.

2, the triangular frame is made up of last rib, the digonous and connecting rod in back.Its cross-sectional plane is an isosceles right triangle, and a square edge is parallel with the underframe longeron, and the right angle length of side is according to the decision of wheel front body length.Respectively there is a horizontal slip axle on the top of forward and backward prism, in the slip skewed slot of interlock case both sides.Two horizontal slip axles are flexibly connected by a connecting rod, and the connecting rod middle part has a spring and interlock case bottom surface to connect, and in the middle of the forward and backward prism a vertical smooth elongated slot is arranged all, and the horizontal flat head screw in the fixed type bearing is in vertical smooth elongated slot.By two horizontal tack slide shafts and two horizontal tack standing screws the triangular frame is connected on the interlock case.The triangular frame can slide up and down along the direction of vertical smooth elongated slot, rotates around anchor shaft, and tack slide shaft and tack standing screw can not stop the translation and the rotation of thruster baffle plate.
3, the thruster baffle plate is to be contained in three of triangular frame bottom the overlapping sheet steel that plays the thruster effect is arranged slightly.There is a Xiao Yuan hole at two jiaos of places, the top of every block of plate, and two screw rods of two mullion inboards penetrate in the two Xiao Yuan holes before and after the triangular frame, and the thruster baffle plate is connected on the triangular frame, and the thruster baffle plate can freely rotate and the front and back small sway around screw rod.In the process that the triangular frame rotate to rise, the thruster baffle plate can be all the time and the ground keeping parallelism, can not run into ground.
4, a unidirectional elasticity retaining head is housed below front slide skewed slot lowest part.It by one advancing slip moving axis is played the retaining head of leverage and barrier effect and spring that one one end is fixed on the interlock casing is formed.On the interlock case, a retaining lower end and spring are separable by a bearing fixing on the top of retaining head.When the elasticity box of current prismatic lower end or thruster baffle plate with the pedestrian who is knocked down by car soft collision took place, because impulsive force is little, elasticity retaining head can stop slide shaft to front slide, and triangular frame and thruster baffle plate still keep vertical position constant.Therefore the thruster baffle plate can will be pushed into by the car by the pedestrian that car knocks down, significantly reduces by wheel to kill or severely injured danger.When elasticity box or thruster baffle plate and road surface protrusion or the hard collision of terraced bank generation, because of impulse force very big, elasticity retaining first speed does not live the axial front slide of front slide, under the combined action of slip skewed slot and fixed type bearing constrained force on impulse force, the interlock case, triangular frame and thruster baffle plate can rotate, rise to highest point voluntarily very soon, broken by ground protrusion or terraced bank avoiding, and any power need not be arranged.
5, in order preventing, to make rotation, rise and be obstructed, except that the A1 type, electrical motor or high-pressure cylinder have been installed all in the interlock case because of parts get rusty.In the preceding rib lower end of triangular frame a crushable elasticity box is housed.There is a pressure to touch switch (the A1 type does not have) and a harder spring in the box, near unidirectional elasticity retaining head, also has in one and the preceding rib lower end elasticity box and press the pressure of touching switch in parallel to touch switch (the A1 type does not have).When elasticity box or thruster baffle plate with the pedestrian who is bumped against soft collision took place, spring deformation was less, press in the elasticity box of preceding rib lower end touch switch or and preceding rib lower end elasticity box in press the pressure of touching switch in parallel to touch switch can not to be switched on.When elasticity box or thruster baffle plate are run into ground protrusion or terraced bank, when hard the collision taken place, spring deformation is bigger, press in the elasticity box of preceding rib lower end to touch switch or touch switch and can be switched on surely with the pressure that elasticity box interior pressure in preceding rib lower end is touched switch in parallel, electrical motor or high-pressure cylinder will be pulled to highest point to triangular frame and thruster baffle plate rapidly by connecting rod, be broken by ground protrusion or terraced bank avoiding.A spring leaf also is housed digonous lower end, back and a pressure is touched switch (the A1 type does not have).When back of automobile was run into ground protrusion or terraced bank, this pressure of back was touched switch and will be switched on, and electrical motor or high-pressure cylinder will also can be pulled to highest point to triangular frame and thruster baffle plate rapidly by connecting rod, was broken by ground protrusion or terraced bank avoiding.Thereby solved the 3rd technical matters.
The present invention mainly is according to mechanics principle and utilizes the kinetic energy of auto against and general electromechanical component, realizes reducing automatically the danger of personal injury in the auto against.Therefore simple in structure, cheap, easy to operate, energy-conserving and environment-protective only expend a little energy when hard collision takes place, other times are consumes energy (the at any time neither consumes energy of A1 type and C1 type) not.Thereby solved the 4th technical matters.
6, in the garage to potholed road the time, because the speed of a motor vehicle is less, the pedestrian is less, and the effect of thruster baffle plate is little, and that can put need not.For this reason, below back slip skewed slot, all settled a strut.On the interlock case, the middle part of bar has a spring that bar is pushed away by a bearing fixing in the lower end of strut, its upper end is in harmony can blocks slip skewed slot notch.On spring, also has an electromagnet.When preceding prismatic lower end elasticity box or thruster baffle plate and the hard collision of ground protrusion generation, or by electric power, vapour pressure is pulled to slide shaft in the process on slip skewed slot top, and the strut lower spring will be compressed, and strut can give way automatically.When slide shaft rose to the top, the strut lower spring can be pushed strut open, blocked the chute mouth, and slide shaft just can not glide, and has been hung in the top, and whole thruster baffle plate is just risen to highest point and left unused.Reach smooth highway, pedestrian more, when needing, can connect manual switch at any time with the thruster baffle plate, give the charging of bar lower electromagnet, the attractive force of electromagnet can be left behind strut, leaves the slip skewed slot, and or else strut plays barrier effect, slide shaft can freedom about, just with not have strut the same.
