[0002] When the temperature of the hydrogen storage bottle is too high due to a vehicle fire or other reasons, the hydrogen storage bottle will continue to be high-temperature and cause the danger of hydrogen explosion. The tail or middle part of the hydrogen bottle, which may cause the temperature-controlled pressure relief valve to fail to detect in time that the hydrogen storage tank is in a state of fire or abnormal local high temperature, and the temperature-controlled pressure relief valve does not operate or has a long delay in action, resulting Damage, risk of hydrogen leak explosion

Embodiment Construction
[0031] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0032] Refer below Figure 1-Figure 4 A gas cylinder 100 for a vehicle and a vehicle having the same according to an embodiment of the present invention will be described.
[0033] Such as figure 1 As shown, the gas storage bottle 100 for vehicles according to the present invention includes: a bottle body 1 , a pretensioning device 2 , a thermal fuse 3 and a pressure relief device 4 .
[0034] Among them, the bottle body 1 is used to contain gaseous fuel (such as high-pressure hydrogen, etc.), the pretension device 2 is used to store elastic potential energy, and the thermal fuse 3 is installed outside the bottle body 1. The thermal fuse 3 is made of a high-temperature fusing material. In some examples, the thermal fuse 3 can be wound on the outer surface of the bottle body 1, and can also be installed nea...

The invention discloses a gas storage bottle for vehicles and a vehicle with the same. The gas storage bottle for vehicles comprises: a bottle body; a pre-tightening device for storing elastic potential energy; wire, the thermal fuse is installed on the body of the bottle, and the thermal fuse is connected to the pre-tensioning device and is used to constrain the pre-tensioning device; pressure relief device, the pressure relief device includes a pressure relief valve , the pressure relief device is connected to the pretension device, wherein the pretension device is configured to release the constraint after the thermal fuse is blown, thereby driving the pressure relief valve to open. According to the gas storage cylinder for vehicles of the present invention, by setting the pretensioning device, thermal fuse and pressure relief device, the gas storage cylinder can quickly detect the abnormal high temperature around the cylinder body, and the pressure relief device responds quickly, No energy consumption, high reliability.
Description
technical field [0001] The invention belongs to the technical field of vehicle manufacturing, and in particular relates to a gas storage bottle for a vehicle and a vehicle with the same. Background technique [0002] When the temperature of the hydrogen storage bottle is too high due to a vehicle fire or other reasons, the hydrogen storage bottle will continue to be high-temperature and cause the danger of hydrogen explosion. The tail or middle part of the hydrogen bottle, which may cause the temperature-controlled pressure relief valve to fail to detect in time that the hydrogen storage tank is in a state of fire or abnormal local high temperature, and the temperature-controlled pressure relief valve does not operate or has a long delay in action, resulting damage, creating a risk of hydrogen leakage and explosion. Contents of the invention [0003] In view of this, the present invention aims to propose a gas storage cylinder for a vehicle and a vehicle having the same, ...
