Description

Disaster preventing and theft-proof device for vehicle

The utility model relates to a kind ofly can prevent car collision, hurt sb.'s feelings, stolen, the device robbed.

Along with increasing of vehicle, car collision, hurt sb.'s feelings, stolen, accident such as robbed constantly takes place, and for this reason, needs a kind of disaster preventing and theft-proof device.

The generation of accidents such as the purpose of this utility model is that a kind of not only anti-misfortune but also theft-proof device will be provided, and it can prevent, reduces car collision, hurts sb.'s feelings, stolen.

The purpose of this utility model is achieved in that in the automobile front loads onto infrared detector, under driver's seat, set up the seat cushion switch, put radio transmitter on one's body at operator's compartment or driver, near brake pedal, load onto oil pressure or pneumatic brake pedal pusher (hereinafter to be referred as pusher) again, and near four wheel cylinder of pusher and automobile, set up the switch (hereinafter to be referred as a minute switch pump) of control oil pressure pipe or air pressure pipe.When the infrared ray detector is received signal or seat cushion switch closure, pushers brake pedal, braking automobile, at this moment, brake signal also passes to radio transmitter, and emitter is passed near four master cocies the wheel cylinder to signal, automobile is just checked, prevent to hurt sb.'s feelings, stolen, robbed.

The utility model is because have the self-actuating brake function, and is highly sensitive, thereby can judge the accident that will take place exactly, the generation of preventing accident.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.

Fig. 1 is the lateral plan of pipe master cock, Fig. 2 is the enlarged drawing of the armature in the middle of the master cock coil shown in Figure 1, Fig. 3 is the concave surface front elevation of the movable board slot of armature shown in Figure 1, Fig. 4 is the coil of master cock and the birds-eye view of armature, Fig. 5 is the scheme circuit of radio transmitter, and Fig. 6 is the scheme circuit of receiver.

On pipe (9) near braking automobile wheel cylinder (13), be equipped with the switch of control pipe shown in Figure 1 (oil pressure pipe or pneumatic tube), it comprises shell (1), coil (6), armature shown in Figure 2 (3), movable board slot (2) shown in Figure 3, receiver 7 shown in Figure 6 etc.Emitter shown in Figure 5 is contained in the pocket carries, after the antenna (8) of receiver is received the signal that emitter sends, coil (6) is connected, and armature (3) moves be inserted in the indentation slideway of board slot (2) by the tingle (12) on top on, earlier by A to B, again by B to C again to D, at this moment, stop transmitter switch, armature (3) just is parked in the D place, square sheet (4) below the armature moves on also, and the passage of pipe (9) is opened.When the transmitter switch that closes again, receiver is received signal again, armature (3) earlier by D to E, under the effect of pull back spring (10), again by E through F to A, shut emitter, armature (3) just is parked in the A place, side's sheet (4) is inserted in the joint square tube of pipe (9), blocks liquid or gas flow.Board slot (2) is the plastic flagstone of ovalize, have smoothness on one surface, one side is dug the slideway of indentation, slideway has the branch of height, the B point is higher than the C point, the C point is higher than the D point, and the D point is higher than the E point, and the E point is higher than the F point, the F point is higher than the A point, the A point is higher than the B point, and there is a circular hole (14) lower end of board slot (2), and the elongated screw (5) that stretches out from shell (1) is inserted in the armature middle slotted hole (11) and circular hole (14), circular hole has a little spring in (14), also be enclosed within on the screw (5), open and close emitter, armature (3) just can move up and down.

Said apparatus must track tramping brake pedal with manpower and realize.If set up a brake pedal pusher near brake pedal, the pipe master cock control with shown in Figure 1 just can realize self-actuating brake.Fig. 9 is the annexation figure of each several part of the present invention.The two ends of drag switch (29) are connected in plug on the two ends of switch of emitter (30), are rigid the connection between the valve piston (18) of oil pressure pipe or pneumatic tube (16) lining and the pusher valve piston (19).In the pusher scheme drawing shown in Figure 7, be equipped with master cock shown in Figure 1 (17) between master cylinder (15) and the valve piston (18), this switch is different with the branch switch pump, coil on the coil of switch (17) and the infrared detector shown in Figure 10 (25) is same coil, switch does not have receiver on (17), D in the movable board slot of switch (17) armature (2) has selected a wiring iron plate, the power on positive pole in source of this iron plate and minute switch pump links to each other, the tingle (12) at the armature top of switch (17) also is a binding post, and the positive pole of power supply control main supply switch (2) is connected on this terminal and the automobile.Seat cushion switch (26) shown in Figure 8 is cylindrical, and top cover (23) and binding post S are arranged at its top, and top cover (23) connects the positive pole of coil in the detector (25).When the driver is on the seat, top cover (23) is depressed, switch (26) disconnects, when the driver is held as a hostage and when leaving the seat, switch (26) is closed under the effect of bottom spring (24), connect switch (17), seal fluid between piston (19) and the piston (20) just promotes brake pedal (22), at this moment, by D point in the movable board slot on the switch (17) and tingle (12), connected the wheel cylinder Switching Power Supply.When the drag switch connection, the switch of emitter (30) is also connected, and sends signal, divides the receiver (28) in the switch pump to receive signal, and armature moves down, and automobile is checked.When detector (25) when receiving signal, move on the armature on the switch (17), pipe (16) is opened, and simultaneously, D point and tingle (12) on the movable board slot of armature are also connected, and the branch switch pump has had power supply, and automobile is checked.In the time will decontroling brake, the switch of the emitter that closes (30) sends signal, divides on the armature in the switch pump and moves, and tube passage is opened.Then, the seat cushion switch (26) that closes again, switch (17) armature moves down, and has blocked gas flow in the pipe (16), and D point on the movable board slot and tingle (12) disconnect, and have cut off the power supply that divides switch pump.No matter be oil brake or compression air brake, what master cylinder (15) the inside was adorned all should be gas, and pressure should reach the 6-7 kilograms per centimeter ²Concerning the oil brake system of no air pump, can on the exhaust pipe of engine, make a freeing pipe switch of opening simultaneously or closing with switch (17), the gas that freeing pipe is discharged is introduced master cylinder (15), when brake need be loosened, can connect the screw switch (31) that drives by small machine, emit the gas in the pipe (16), piston (18) is just return under the effect of pull back spring (32), one square M is arranged on the piston (18), it can be against on the square sheet below the armature of switch (17), with the side's of preventing sheet by the gas in the master cylinder press distortion.When the debugging transmitter and receiver, suitably choose C ₂, C ₃And R ₁, R ₂, make emitter be operated in short-wave band, regulate C ₁, the oscillation frequency of emitter is adjusted, regulate C ₄, can make to receive well.
