Problems solved by technology
When the driver forgets to close the shut-off valve 2 after the vehicle is turned off, and there is a chronic air leakage phenomenon at the connection between the gas pipeline 20 and the pneumatic components using pressure gas, the pressure gas in the gas bag 3 will be released after the vehicle is parked for a period of time. If it is omitted, the vehicle will not start when it needs to be started
When the driver forgets to open the cut-off valve 2 before the vehicle starts, the vehicle will also fail to start

Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings and the given embodiments.
[0015] like figure 1 As shown, an air bag control device for a vehicle includes an air bag 3, a start valve 4, a relay valve 5, an air motor 7, a gas pipeline 20, a power source 21, a generator 22 and a main power switch 23; The model can be XQ230420.1, when the driver presses the button 4-1 of the starting valve 4, the execution port A of the air inlet P of the starting valve 4 is connected, and when the driver releases the button 4-1 of the starting valve 4 , the button 4-1 of the starting valve 4 is automatically reset, and the execution port A of the starting valve 4 is communicated with the air outlet T at this time. The model of the relay valve 5 may be SRV100 of Ingersoll Rand. The generator 22 may be a model FB-500 / 24Y. The execution port A of the relay valve 5 communicates with the air intake port of the air motor 7 . The power s...

An air bag control device for a vehicle, comprising an air bag, a start valve, a relay valve, an air motor, a gas pipeline, a power supply, a generator, a main power switch, an electromagnetic reversing valve, a relay and a pressure switch; The air inlet P is communicated with the air bag, and the execution port A of the electromagnetic reversing valve is communicated with the air inlet P of the start valve and the air inlet P of the relay valve respectively; the execution port A of the start valve is respectively connected with the air control of the pressure switch. The port K is connected with the control port K of the relay valve; the terminal N of the generator is electrically connected with one end of the coil of the relay, and the other end of the coil is grounded; the other end of the terminal K of the electromagnetic reversing valve is connected with one end of the switch of the relay Electrical connection, the other end of the switch is grounded; the pressure switch is connected in parallel at both ends of the switch of the relay. The invention can realize that the pressure gas in the air bag can not automatically enter the gas pipeline and the pneumatic components after the vehicle is turned off, and the pressure gas in the air bag can automatically enter the gas pipeline and the pneumatic components when it is started.
Description
technical field [0001] The present invention relates to a vehicle, in particular to an air bag control device of the vehicle. Background technique [0002] When the vehicle runs in an environment with flammable gas, the electrical components on the vehicle need to have explosion-proof function. Due to the large size and high cost of explosion-proof electrical components, vehicles running in the environment of flammable gas often use gas The starting system, for example, the neutral starting device for a trackless rubber-wheeled vehicle disclosed in Chinese patent document CN204354825U (application number 201420708982.5) adopts an air starting system. like figure 2 As shown, the above-mentioned neutral starting device for the trackless rubber-wheeled vehicle includes an air compressor 1, a cut-off valve 2, an air bag 3, a starting valve 4, a relay valve 5, an air motor 7 and a gas pipeline 20; The air outlet is connected to the air bag 3, the air outlet of the shut-off valv...
