Automatic hydrogenation switch device and fuel cell vehicle

Abstract

The invention discloses an automatic hydrogenation switch device and a fuel cell vehicle. The automatic hydrogenation switch device comprises a hydrogenation switch, a linkage pressing structure and an elastic piece, when a hydrogenation door of the fuel cell vehicle is closed, the elastic piece provides elastic force to enable the linkage pressing structure to abut against the hydrogenation door; and after the hydrogenation door is opened, the linkage pressing structure acts under the reset action of the elastic piece so as to press the hydrogenation switch. According to the scheme of the automatic hydrogenation switch device, disconnection and connection of the hydrogenation switch can be achieved in a linkage mode according to opening or closing of the hydrogenation door, so that automatic control over the hydrogenation switch is achieved, manual operation for connection and disconnection is not needed, operation is easy, convenient and reliable, and the situation that a low-voltage power source of the vehicle is used up due to the fact that the hydrogenation switch is forgotten to be closed due to manual reasons can be avoided.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automatic hydrogenation switch device and a fuel cell vehicle. Background technique [0002] A fuel cell vehicle is a vehicle that uses hydrogen as a driving energy source. Fuel cells convert the chemical energy produced by the reaction of hydrogen and oxygen into electricity. Hydrogen is stored in the high-pressure hydrogen storage cylinder of the hydrogen storage system in the form of high-pressure gas on the fuel cell vehicle. The type of high-pressure hydrogen storage bottle can be divided into 35MPa and 70MPa according to the pressure. [0003] Hydrogen is a flammable and explosive gas, and a hydrogen leak sensor should be arranged at the location where the vehicle hydrogen storage system pipeline passes to detect whether there is a hydrogen leak. Data from the hydrogen leak sensor is transmitted to the fuel cell system controller in proportional voltage form. Whe...

AI Technical Summary

Problems solved by technology

The operation is cumbersome, and if the hydrogenation switch is not turned off after hydrogenation, the 12V low-voltage power supply of the fuel cell vehicle will always be in the power supply state. Once the vehicle is idle for a long time, the fuel cell 12V power supply will be short of power, and the auxiliary system of the vehicle will not be able to start
