Embodiment 1

[0038] Embodiment 1: as Figures 1 to 7 as shown,

[0039] A hand-held fuel cell vehicle hydrogenation gun, which includes a filling gun body 1, the filling gun body 1 includes a filling end and an air intake end, and the filling end is connected to a hydrogenation port 9 of a hydrogen fuel cell vehicle , the inlet port is connected to the hydrogenation machine;

[0040] Specifically, the air inlet end of the filling gun body 1 is also provided with an air inlet joint 8, and the air inlet joint 8 communicates with the hydrogenation machine through a corrugated protective pipe 801.

[0041] The filling end is fixedly connected with a fixed cylinder 2, and the inner wall of the fixed cylinder 2 is movably provided with a one-way valve core 201 that can move axially along the fixed cylinder 2, and the one-way valve core 201 can be inserted into the hydrogen fuel cell The vehicle hydrogenation port 9 communicates the hydrogen fuel cell vehicle hydrogenation port 9 with the hydrog...

Embodiment 2

[0057] Embodiment 2: as Figures 2 to 5 Shown, for utilizing a kind of operation process of safely filling hydrogen implemented by the present invention:

[0058] 1) The hydrogenation gun is inserted into the hydrogenation port of the hydrogen fuel cell vehicle, and the trigger is pulled, so that the plastic push cylinder and the claw slider move forward, the claws of the hydrogenation port shrink radially, and engage with the trapezoidal ring groove of the hydrogenation port, and at the same time , the trigger and the trigger lock are engaged with each other, the one-way valve core is resisted by the hydrogenation port, and the one-way valve core overcomes the spring force of the valve core and moves back axially. Open the refueling path between the one-way valve core and the hydrogen refueling port of the hydrogen fuel cell vehicle. Open the gas outlet of the hydrogenation gun, and open the gas filling button at the hydrogenation machine. Under the force of the air pressure...

Abstract

The invention discloses a handheld fuel cell car hydrogenation gun, belongs to the technical field of hydrogen fuel cell cars, and in particular, relates to a fuel cell car hydrogenation gun operatedby one hand and with sealing and leakage preventing performances. The fuel cell car hydrogenation gun comprises an injecting gun body; and a fuel cell car hydrogenation port is connected with a hydrogenation machine by an injecting gun. The fuel cell car hydrogenation gun further comprises a guide mechanism and a control mechanism; the guide mechanism is arranged on the outer wall of a fixed cylinder, and can move relative to the axial direction of an injecting end to clamp the hydrogen fuel cell car hydrogenation port; and the control mechanism is arranged in the middle position of the injecting gun body, and controls the guide mechanism to move relative to the axial direction of the injecting end. The fuel cell car hydrogenation gun solves the problems of complicated operation due to most double-hand holding operating modes in the prior art, high explosion-proof requirement on injection of fuel hydrogen and probable generation of such accidents as pipe burst, further can satisfy thetechnical index that the higher the pressure in the gun body and a high-pressure hose is, the higher the tightness and safety requirements are; and a sealing material has self-lubrication and high molecular structures at the same time.

Description

technical field [0001] The invention belongs to the technical field of hydrogen fuel cell vehicles, in particular to a hand-held fuel cell vehicle hydrogenation gun. Background technique [0002] The energy problem is one of the important problems facing society today, and the energy of fossil fuels will eventually be exhausted. Therefore, the development of new energy sources is the trend pursued by today's society, and fuel cells that are environmentally friendly are a trend in the development of new energy sources. [0003] Fuel cells use electrochemical reactions instead of combustion (gasoline, diesel) or energy storage (battery batteries)—the most typical traditional backup power solutions. Combustion releases pollutants like COx, NOx, SOx gas and dust. As mentioned above, fuel cells only produce water and heat. If the hydrogen is produced by renewable energy sources (photovoltaic panels, wind power, etc.), the entire cycle is completely free of harmful emissions. ...
