Abstract

The invention provides a quick release device and a fuel cell vehicle, the quick release device is used for a hydrogen storage bottle in the fuel cell vehicle, and the quick release device comprises a gas release passage connected with the hydrogen storage bottle and an action switch arranged in the gas release passage in a normally closed state; the first circuit is used for controlling or accelerating the starting of the action switch and comprises a temperature control switch arranged close to a battery pack of the fuel cell vehicle; after the temperature control switch reaches a first preset temperature, the first circuit is switched on. The temperature control switch is arranged near the battery pack, and when the battery pack of the automobile is on fire, the temperature control switch is heated to reach the first preset temperature and then is quickly closed, so that the first circuit is switched on, the action switch is electrified to open the gas release passage, and hydrogen in the hydrogen storage bottle is quickly discharged through the gas release passage. In the whole exhaust process, the temperature control switch is close to the position of a fire source, the time for heating to reach the first preset temperature is short, and the response speed of the whole quick relief device is increased.

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...
