The main points of technique scheme are that automatic lifting thruster baffle plate significantly reduces the danger that in the auto against driver, passenger and car body physical construction is caused major injury before adopting two-stage high-pressure cylinder energy disperser that is fixed on vacancy in the automobile chassis frame longeron front-end and back-end and the front-wheel that is fixed on automobile chassis frame front end longeron two outsides and two front-wheel the place aheads, significantly reduce simultaneously pedestrian before the car is collided to death, kills and severely injured danger
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 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.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.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 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, reduced the suffered maximum impact force of automobile, reduced automobile itself and driver and passenger may be subjected to the danger of major injury.Thereby solved second technical matters.
Automatic lifting thruster baffle plate is made up of interlock case, crane and thruster baffle plate before the front-wheel.Because structure is different with engine installation, they have been divided into 14 types: change unpowered automatic lifting thruster baffle plate (hereinafter to be referred as the A1 type) before and after (1) triangular frame; (2) change electric chain automatic lifting thruster baffle plate (hereinafter to be referred as the A2 type) before and after the triangular frame; (3) change electric gear automatic lifting thruster baffle plate (hereinafter to be referred as the A3 type) before and after the triangular frame; (4) change vapour pressure automatic lifting thruster baffle plate (hereinafter to be referred as the A4 type) before and after the triangular frame; (5) change electric chain automatic lifting thruster baffle plate (hereinafter to be referred as the B1 type) behind the triangular frame; (6) change electric gear automatic lifting thruster baffle plate (hereinafter to be referred as the B2 type) behind the triangular frame; (7) change vapour pressure automatic lifting thruster baffle plate (hereinafter to be referred as the B3 type) behind the triangular frame; (8) change unpowered automatic lifting thruster baffle plate (hereinafter to be referred as the C1 type) before and after single rib frame; (9) change electric chain automatic lifting thruster baffle plate (hereinafter to be referred as the C2 type) before and after single rib frame; (10) change electric gear automatic lifting thruster (hereinafter to be referred as the C3 type) before and after single rib frame; (11) change vapour pressure automatic lifting side shield (hereinafter to be referred as the C4 type) before and after single rib frame; (12) change electric chain automatic lifting thruster baffle plate (hereinafter to be referred as the D1 type) behind single rib frame; (13) change electric gear automatic lifting thruster baffle plate (hereinafter to be referred as the D2 type) behind single rib frame; (14) change vapour pressure automatic lifting thruster baffle plate (hereinafter to be referred as the D3 type) behind single rib frame, following A1 type-A4 type general designation A type, B1 type-B3 type general designation Type B, C1 type-C4 type general designation C type, D1 type-D3 type general designation D type.
The common trait of A, Type B is:
1, the cross-sectional plane of interlock case is all the short rectangle of high length and width, and middle higher, two is lower, and it is 30 ° paired slip skewed slot that same upward-inclination angle is arranged on the two side, and before and after the two edges, bottom surface a pair of fixed type bearing, rotating shaft wherein being arranged respectively is flat head screw.Also have some connecting rods and engine installation (the A1 type does not have) in the case;
2, crane is by last rib, the back is digonous and connecting rod is formed triangular frame.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 rib, in the slip skewed slot of interlock case both sides.In the middle of prismatic an elongated slot is arranged, the tack horizontal screw bolt in the fixed type bearing is in elongated slot.By two tack horizontal slip axles and two tack horizontal fixed screw rods the triangular frame is connected on the interlock case.The triangular frame can slide up and down along the direction of elongated slot, rotates around anchor shaft, and tack horizontal slip axle and tack horizontal fixed screw rod 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 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 preceding horizontal slip axle.It by one preceding horizontal slip axle 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 soft collision took place, because impulsive force is little, unidirectional elasticity retaining head can stop the axial front slide of horizontal slip, 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 bigger, the incessantly preceding axial front slide of horizontal slip of unidirectional elasticity retaining first speed, 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, are broken by ground protrusion or terraced bank avoiding.
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 utility model mainly is according to mechanics principle and utilizes the kinetic energy of auto against and general electromechanical component, the danger of personal injury and mechanical damage in the automatic minimizing of the realization auto against.Therefore simple in structure, cheap, easy to operate, only when taking place, hard collision expends a little energy, and 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 the slip skew notch.Below 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 the horizontal slip axle in the process on slip skewed slot top, and the strut lower spring will be compressed, and strut can give way automatically.When the horizontal slip axle rose to the top, the bar lower spring can be pushed strut open, blocked the chute mouth, and the horizontal slip axle 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, strut can be left behind, leave the slip skewed slot, or else strut plays barrier effect, the horizontal slip axle can freedom about, just with not have strut the same.
The common trait of A type:
1, before and after in the interlock case two horizontal slip axles respectively have a pair of forward, 30 ° the long slip skewed slot of being inclined upwardly, also have a pair of backward, 30 ° long slip skewed slot is inclined upwardly.
2, in order to shorten forward and backward prism and the interaxle distance of forward and backward slip, to adapt to the short needs of front-wheel front body, the slip skewed slot that the interlock case is gone forward after the horizontal slip axially will inevitably intersect with the slip skewed slot before the back horizontal slip axially, cause the horizontal slip axle that in a slip skewed slot, slides to be absorbed in the slip skewed slot of another horizontal slip axle, can not in a slip skewed slot, slide the purpose that out of reach rises always.For this reason, at two groove infalls, the both sides of slip skewed slot have been welded the steel slide block of a bridge pier type respectively, have also overlapped a bridge type steel slide block that can rotate around the horizontal slip axle below the horizontal slip axle.When the horizontal slip axle was crossed two groove infalls, bridge type steel slide block can slide on two bridge pier type steel slide blocks, thereby avoided a horizontal slip axial depression in the slip skewed slot to go in the slip skewed slot of another horizontal slip axle.They are suitable for the less automobile in space and install.
The feature of A1 type: in the elasticity box of the forward and backward prismatic lower end of triangular frame, do not press and touch switch, in the interlock case without any engine installation.But below front and back horizontal slip axle, also all adorned a strut.When hard collision takes place in (or backward) forward in the horizontal slip axle, can be along () leaning angle is that 30 ° slip skewed slot slides rising automatically or backward, simultaneously the thruster baffle plate is promoted to highest point, and is propped up by strut, hangs over the top and without any need for power forward.Can connect manual switch at any time, give the charging of bar lower electromagnet, strut can be left behind, leave the slip skewed slot, or else strut plays barrier effect.Its structure is the simplest, and almost without any need for operation, cost is the cheapest, and the interlock case is also very short.But need often prevent that parts from getting rusty.It is suitable for the less automobile of front-wheel rear space and installs.
The feature of A2 type: drive the horizontal slip axle by electrical motor by chain, connecting rod, it is risen rapidly along the slip skewed slot, the reason parts do not get rusty and are obstructed, and the interlock case is also shorter.4 hilted broadswords pressures are housed on it touch switch: press in the elasticity box of preceding rib lower end and touch switch, press in the elasticity box of back rib lower end and touch switch, touch switch to front slide skewed slot highest point pressure, slide backward skewed slot highest point pressure and touch switch, two relays, a double pole double throw, an electrical motor.When automobile when (or backward), hard collision took place forward, elasticity box interior pressure in preceding rib lower end is touched switch (or pressure is touched switch in the elasticity box of rib lower end, back) and is switched on, the portable plate of double pole double throw turns to down (or on) end, electrical motor energising is also rotated along (or contrary) hour hands, by chain, connecting rod the horizontal slip axle is pushed to backward, is pressed to front slide skewed slot highest point and touch switch place (or slide backward skewed slot highest point press touch the switch place).When sliding to the top, the horizontal slip axle presses when touching switch (or slide backward skewed slot highest point press touch switch) to front slide skewed slot highest point, press to front slide skewed slot highest point and to touch switch (or slide backward skewed slot highest point press touch switch) and will be switched on, down the relay of (or on) face will disconnect, electrical motor stops operating, be fixed on the spring on the movable rod between two slide shafts, connecting rod is retracted lowest part, get back to original position.Connect two manual switches, the horizontal slip axle can be fixed on highest point, with the thruster baffle plate is unsettled need not.It is suitable for the big slightly automobile of front-wheel rear space and installs.
