Abstract

The invention provides a quick release device and a fuel cell vehicle, wherein the quick release device is used for the hydrogen storage bottle in the fuel cell vehicle, and includes a gas release passage connected to the hydrogen storage bottle and an action that the normally closed state is set in the gas release passage The switch also includes a first circuit that controls or accelerates the opening of the action switch. The first circuit includes a temperature control switch that is set close to the battery pack of the fuel cell vehicle; the temperature control switch turns on the first circuit after reaching the first preset temperature. By setting the temperature control switch near the battery pack, when the battery pack of the car catches fire, the temperature control switch will be closed quickly after being heated to its first preset temperature, so that the first circuit will be conducted, so that the action switch will be opened and vented after being energized. The hydrogen in the hydrogen storage bottle is quickly discharged through the leaking passage. During the entire exhaust process, the temperature control switch is close to the fire source, and the time it takes for the heat to reach the first preset temperature is short, which improves the response speed of the entire quick release device.

Description

technical field [0001] The invention relates to the technical field of fuel cell vehicles, in particular to a quick release device and a fuel cell vehicle. Background technique [0002] A fuel cell vehicle is a vehicle powered by electricity generated by a vehicle-mounted fuel cell device. The outside air is inhaled through an air compressor and undergoes a redox reaction with the hydrogen in the fuel cell device to generate electricity for driving the vehicle. The hydrogen in fuel cell vehicles is stored in hydrogen storage bottles. When a fuel cell vehicle encounters a traffic accident, it may cause the internal power battery to catch fire, which in turn threatens the hydrogen storage bottles containing a large amount of hydrogen. Therefore, how to ensure the hydrogen storage bottles Fire safety has become a research hotspot. [0003] In the related technology, the hydrogen storage bottle is generally arranged at a position far away from the power battery, and a bottle va...
