[0002] Hydrogen fuel cells use hydrogen and oxygen to react chemically to generate electricity. Hydrogen fuel cells are environmentally friendly. They use electrochemical reactions instead of combustion or energy storage. Fuel cells only produce water and heat. If hydrogen is produced through renewable energy, the entire cycle is a process that completely produces no harmful emissions. It can provide a zero-emission power system and reduce dependence on fossil fuels. Due to the low density and high pressure requirements of hydrogen, a hydrogen storage device is needed to store hydrogen in a safe and effective manner. When the hydrogen storage device is moving, the bumps of the vehicle can easily cause the storage device to be unstable and not safe. Utility Model Content

[0005] The beneficial effects of the utility model are:

[0006] The airbag and the buffer mechanism absorb vibration force and provide buffer protection for the internal gas cylinder. The airbag and the buffer mechanism are evenly distributed front and back on the gas cylinder to disperse the pressure on the airbag, thereby improving the pressure resistance and service life of the airbag. The buffer mechanism provides buffering to prevent the airbag from being damaged by instantaneous impact. The double combination performs buffering in sequence to improve the protection effect.

[0016] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there can be an intermediate element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element at the same time:

[0018] Embodiment 1:

[0019] Reference Figure 1-Figure 7 According to an embodiment of the utility model, a hydrogen fuel cell hydrogen storage cylinder includes a gas cylinder 12, a fixing plate 13 evenly distributed in front and back is provided at the lower end of the gas cylinder 12, a connecting pipe 11 is fixedly provided at the front end of the gas cylinder 12, and two symmetrical stabilizing sleeves 10 are provided at the outer end of the gas cylinder 12, a support platform 23 is fixedly provided at the upper end of each fixing plate 13, and the support platform 23 is arranged in a V shape to abut against the two stabilizing sleeves 10, and the upper end of the fixing plate 13 and the left and right parts of the fixing plate 13 are hinged with a hinge plate 14, and the two adjacent hinge plates 14 are connected with a support plate 15 at the ends close to each other, and the two support plates 15 are far away from each other. The ends of the two support plates 15 are fixed with a stabilizing frame 16, which is in contact with the hinged plate 14. The ends close to each other of the two support plates 15 are fixed with a supporting frame 17. The trapezoidal opening of the supporting frame 17 is arranged to be in contact with the upper and lower ends of the two stabilizing sleeves 10. Each stabilizing sleeve 10 is connected with an air bag 21 and a buffer mechanism 22 evenly distributed in the front and back. The buffer mechanism 22 is divided into two groups up and down and connected with the two stabilizing sleeves 10. The buffer mechanism 22 includes a sliding sleeve 18 fixed on the stabilizing sleeve 10, and a sliding rod 19 is slidably connected in the sliding sleeve 18. A buffer spring 20 is connected between the sliding rod 19 and the stabilizing sleeve 10, and the sliding rod 19 is in contact with the end surface of the gas cylinder 12.

[0020] The two stabilizing sleeves 10 are butted against each other, and support frames 17 are provided at the left and right ends of the two stabilizing sleeves 10. The stabilizing sleeves 10 are supported by the support frames 17, so that the airbags 21 in the stabilizing sleeves 10 are butted against the outer peripheral surface of the buffer mechanism 22 and the gas cylinder 12. The airbags 21 and the buffer mechanism 22 absorb the vibration force, and the internal gas cylinder 12 is buffered and protected. The airbags 21 and the buffer mechanism 22 are evenly distributed on the gas cylinder 12 in front and back to disperse the pressure on the airbags. When the support frame 17 is impacted by the stabilizing sleeve 10, the impact force is concentrated on the connection part between the support frame 17 and the support plate 15, and the stabilizing frame 16 on the support plate 15 is butted against the hinged plate 14 to prevent the support frame 17 from being separated from the stabilizing sleeve 10.

[0021] During maintenance, the user pulls the stabilizing frame 16 upwards to make the support plate 15 fixedly connected to the stabilizing frame 16 move synchronously. Under the hinge connection of the hinge plate 14 and the fixed plate 13, and the hinge connection of the hinge plate 14 and the support plate 15, the support frame 17 deflects upward and rotates with the stabilizing sleeve 10 as the rotation axis, and then the pulling force at the stabilizing frame 16 disengages the abutment with the stabilizing sleeve 10, so that the two stabilizing sleeves 10 can be taken out.

[0022] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
