Abstract

The utility model relates to a safety fire-proof controller for the fuel tank of car. Four accidental spring break off implements are permanently installed on the four angle points of the front and the back of an automobile. An accidental spring break off implement, a vehicle accumulator, a driver key switch K < 1 >, a solenoid switch K< 2 >, an electronmaqnetic valve, two resistors, and two light-emitting diodes are connected with each other to form a return device. The oil circuit on-off is controlled by the electromagnetic valve. The light-emitting diode < 1 > is a green light, and the light-emitting diode < 2 > is a red light. The light-emitting diode < 1 > and the light-emitting diode < 2 > are arranged in an instrument tray of an operation cabin. The utility model has the advantage that the oil way is automatically closed when the automobile is encountered the accidental collision accident, as a result, the explosion accident of the fuel tank conduced by the oil way fire can be avoided.

Description

Safety fire-proof controller for fuel tank of car

The utility model relates to a kind of automobile oil circuit fire safety controller.

At present, do not have corresponding control structure between the circuit of automobile and the oil circuit, its deficiency is: when automobile ran into unexpected car accident, oil circuit can not closed voluntarily, if when running into accident on fire, will form oil circuit and catch fire and cause the danger of fuel tank explosion.

The purpose of this utility model is to provide a kind of automobile oil circuit fire safety controller, the on off operating mode of its circuit has a corresponding control structure with the keying state of oil circuit, when automobile ran into unexpected car accident, oil circuit was closed voluntarily, thereby avoided oil circuit to catch fire causing the generation of fuel tank explosion accident.

Task of the present utility model is finished like this: at the disconnected device of four unexpected bullets of four angles, front and back place's fixed installation of automobile, the lead of exporting from car accumulator is welcomed the emperor and is sailed indoor driver's key operation K ₁After the electromagnetic valve switch K in the disconnected device of unexpected bullet and operator cabin before two that connects again ₂Two-way, one tunnel series resistors R are divided in the back ₁And LED ₁Back ground connection is divided two-way, one tunnel series resistors R behind solenoid valve of another road series connection again ₂And LED ₂Back ground connection, another road ground connection behind the disconnected device of unexpected bullet of connecting again after two, the keying of electromagnetic valve oil circuit, diode (LED) ₁Be green light, LED ₂Be red light, in the instrument panel of device in operator cabin.

The utility model compared with prior art has when automobile runs into unexpected car accident, and oil circuit is closed voluntarily, thereby avoids oil circuit to catch fire causing the characteristics of the generation of fuel tank explosion accident.

Detailed enforcement of the present utility model will provide in conjunction with the accompanying drawings:

Fig. 1 is the schematic diagram of automobile oil circuit fire safety controller;

Fig. 2 is the structural drawing of the disconnected device of unexpected bullet in the automobile oil circuit fire safety controller.

At the disconnected device of four unexpected bullets of four angles, front and back place's fixed installation of automobile, the lead of exporting from car accumulator is welcomed the emperor and is sailed indoor driver's key operation K ₁After connect again disconnected device (1) of unexpected bullet and the interior electromagnetic valve switch K of operator cabin before two ₂Two-way, one tunnel series resistors R are divided in the back ₁And LED ₁Back ground connection is divided two-way, one tunnel series resistors R behind another road solenoid valve of series connection (3) again ₂And LED ₂Back ground connection, another road ground connection behind the disconnected device of unexpected bullet of connecting again after two, the keying of solenoid valve (3) control oil channel (4), LED ₁Be green light, LED ₂Be red light, in the instrument panel of device in operator cabin.

Circuit working state with regard to automobile is explained as follows now: when automobile remains static, and driver's key operation K ₁Disconnect, do not have electric current to pass through in the circuit, the oil circuit (4) of solenoid valve (3) control is in closed condition, and oil circuit (4) can not fuel feeding; As driver's opening automobile key operation K ₁With connection electromagnetic valve switch K ₂The time, the electric current in the circuit is through automobile key switch K ₁, the disconnected device (1) of preceding unexpected bullet, electromagnetic valve switch K ₂Two-way is divided in the back, and one the tunnel through resistance R ₁And LED ₁Back ground connection, another road by the disconnected device of the unexpected bullet of solenoid valve (3) and back after ground connection, owing to resistance R ₂Resistance big (1000 ohm), electric current does not pass through resistance R ₂And LED ₂, at this moment, LED ₁(green light) is bright, and the oil circuit (4) of solenoid valve (3) control is in opening state, oil circuit (4) normal fuel injection; When the disconnected device (1) of current unexpected bullet was severed, entire circuit was cut off, and does not have electric current to pass through in the circuit, at this moment LED ₁LED ₂All no current passes through, and is not luminous, and the oil circuit (4) of solenoid valve (3) control is in closed condition, and oil circuit (4) can not fuel feeding; When the disconnected device of the unexpected bullet in back was severed, the electric current in the circuit was through automobile key switch K ₁, the disconnected device (1) of preceding unexpected bullet, electromagnetic valve switch K ₂Two-way is divided in the back, and one the tunnel through resistance R ₁And LED ₁Back ground connection, another road are passed through solenoid valve (3) after resistance R ₂And LED ₂Back ground connection, at this moment, LED ₁(green light) and LED ₂(red light) is all bright, because resistance R ₂Resistance big (1000 ohm), very little by the electric current of solenoid valve (3), solenoid valve (3) can not be opened oil circuit (4), the oil circuit (4) of solenoid valve (3) control is in closed condition, oil circuit (4) can not fuel feeding.

Electromagnetic valve switch K ₂Effect be to be convenient to the safety of automobile repair and park, if the driver wants to repair, weld fracture in driving procedure or when stopping, close electromagnetic valve switch K in advance ₂Electric current in the circuit is cut off, the oil circuit (4) of solenoid valve (3) control is in closed condition, oil circuit (4) can not fuel feeding, but the surplus oil in the oil circuit (4) can continue to be drawn into vacuum state by automobile carburetor, being maintained to motor does not have till the oily auto extinguishing, makes not surplus oil in the oil circuit when repairing or stopping (4), has improved safe performance.

The structure of the disconnected device of the unexpected bullet in the utility model can design and become on the fixed support with fastening screw (5), fix a hollow glass tube (6), three springs (7) are housed in the glass tube (6), accompany between the spring (7) and isolate copper sheet (8), glass tube (6) two has a pot shape fixed copper cap (9) to be inlaid on the support (1), draw lead from pot shape fixed copper cap (9), the spring (7) in the glass tube (6) directly contacts with pot shape fixed copper cap (9).When the disconnected device of unexpected bullet was subjected to clashing into, glass tube (6) was crashed or is shatter, and spring (7) drops out, and circuit promptly is cut off.

The utility model also can be set up a temperature-sensitive thermoswitch K by temperature-sensitive thermally-responsive controls (2) control in circuit ₃, temperature-sensitive thermoswitch K ₃Be commutator, ground connection behind buzzer BZ of another stationary contact series connection.When automobile caught fire, temperature-sensitive thermally-responsive controls (2) expanded by heating is the warm quick K switch of sense of control voluntarily ₃Disconnect the circuit of solenoid valve (3) and close oil circuit (4), connect buzzer simultaneously, and send chimes of doom.
