Vehicle gasoline tank and flameout linkage device

Abstract

A gasoline tank and flameout linkage device of a vehicle comprises a flameout mechanism and a gasoline tank. The flameout mechanism comprises a gas bag, a manual gas pressure reversing valve, a flameout gas cylinder, a solenoid gas pressure reversing valve, a first one-way valve, a second one-way valve and a main controller. The gasoline tank comprises a tank body, a gasoline filling port, a floating ball box, a first magnetic switch, a second magnetic switch and a magnetic floating ball. A gas inlet of the solenoid gas pressure reversing valve communicates with the gas bag; an execution portof the solenoid gas pressure reversing valve communicates with the second one-way valve; the second one-way valve communicates with a rodless cavity of the flameout gas cylinder; the upper end of thefloating ball box is connected with the lower end of the gasoline filling port; an inner cavity of the floating ball box communicates with an inner cavity of the gasoline filling port and an inner cavity of the tank body; the magnetic floating ball is freely placed in the inner cavity of the floating ball box; the first magnetic switch and the second magnetic switch are connected to the inner wallof the floating ball box; and the connection end K of the solenoid gas pressure reversing valve, the first magnetic switch and the second magnetic switch are all electrically connected with the maincontroller. During gasoline filling, an engine conducts automatic flameout.

Description

Technical field [0001] The invention relates to a vehicle, in particular to a linkage device of a gasoline tank and flameout of a vehicle. Background technique [0002] When the vehicle needs gasoline, it is generally necessary to turn off the vehicle. This is because the gas flow in the intake and exhaust pipes and the slight aging of the wiring during the normal operation of the vehicle will generate static electricity and even sparks, and the gasoline is easy to volatilize. If the vehicle is not stalled, there is a danger of detonating gasoline when the gasoline volatilizes to a certain concentration. There is no linkage between the gasoline tank and the flameout mechanism of the existing vehicle, that is, the engine cannot be automatically shut down when refueling. In this way, when the driver forgets to turn off the vehicle and directly adds gasoline, there is a danger of detonating gasoline, and the safety is not high. Existing flameout mechanisms such as figure 2 As shown...

[0002] When the vehicle needs to be filled with gasoline, it is generally necessary to turn off the vehicle. This is because the gas flow in the intake and exhaust pipes and the subtle aging of the wiring will generate static electricity or even sparks during the normal working process of the vehicle, and gasoline is easy to volatilize. If the vehicle is not turned off, there is a danger of detonating gasoline when the gasoline volatilizes to a certain concentration

There is no linkage between the gasoline tank and the flameout mechanism of existing vehicles, that is, the engine cannot be automatically flamed out when refueling, so when the driver forgets to turn off the vehicle and directly refills gasoline, there is a danger of detonating gasoline, and the safety is not high
