Problems solved by technology

This device has the following disadvantages: hydrogen fuel cell vehicles will inevitably vibrate during driving, which will cause severe axial vibration of the gas cylinder, thereby aggravating the wear of the rubber pad, and the replacement of the rubber pad is very frequent
In addition, the fixing of the hydrogen supply system pipeline connected to the gas cylinder is not ideal, and there are also defects of wear and vibration damage
[0005] In addition, the gas cylinder fixing device in the vehicle-mounted hydrogen storage system is based on the above-mentioned gas cylinder fixing device, adding pre-tightening bolts that can adjust the tension of the hoop, but this is only an increase in the pre-tightening force, not fundamentally Solve the problem of rubber pad wear caused by vibration, the friction between the rubber pad and the cylinder still exists, and the replacement of the rubber pad is more troublesome
In addition, the vibration will also cause the pre-tightened bolts to loosen, posing a risk

Embodiment 2

[0027] The difference between this embodiment and the first embodiment is that several fixing clips 7 for fixing the pipeline 20 of the hydrogen supply system connected with the gas cylinder 2 are provided in the fixing frame 1 . Such as Figure 6 , Figure 7 and Figure 8 As shown, the fixing clip 7 described in this embodiment includes: an upper fixing plate 8, a pipe clamp rubber pad 9, a lower fixing plate 10 and a bolt 11, and the fixing clip 7 usually fixes the lower fixing plate 10 on the fixed frame 1. A horizontal through hole 91 is provided on the pipe clamp rubber pad 9, an opening 92 is provided on one side of the pipe clamp rubber pad 9, the opening 92 runs through the side wall of the horizontal through hole 91 horizontally, and the gap H between the upper and lower sides of the opening 92 is 1 ~2mm, the pipeline 201 of the hydrogen supply system pipeline 20 can be snapped into the horizontal through hole 91 through the opening 92 . A vertical through hole is...

Abstract

The invention discloses a gas cylinder fixing device in a vehicle-mounted hydrogen storage system. The gas cylinder fixing device includes fixing frames, gas cylinders are horizontally fixed into thefixing frames through straps with rubber cushions, axial fixing assemblies are arranged on the fixing frames of both ends of the gas cylinder correspondingly, according to the structure of the axial fixing assemblies, supporting plate assemblies are fixedly arranged on the fixing frames, supporting rubber cushions are arranged on the supporting plate assemblies, and the supporting surfaces of thesupporting rubber cushions on the two axial fixing assemblies are closely attached to the spheres of both ends of the gas cylinders correspondingly. The gas cylinder fixing device can effectively alleviate axial vibration of the gas cylinders, and reduces wear of the rubber cushions and hydrogen supply system pipelines.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted hydrogen storage, in particular to a gas cylinder fixing device in a vehicle-mounted hydrogen storage system. Background technique [0002] Hydrogen energy has the characteristics of abundant reserves, wide range of sources, high energy density, recyclable utilization, and zero emission of greenhouse gases and pollutants. Hydrogen energy is regarded as an important bridge connecting fossil energy and renewable energy. [0003] In the 1990s, countries rushed to start research on new energy vehicles, especially hydrogen fuel cell vehicles. Based on the fact that hydrogen fuel cell vehicles must meet the requirements of high efficiency, safety, and low cost, on-board hydrogen storage technology is the top priority for the development of hydrogen fuel cell vehicles. [0004] The gas cylinders in the vehicle-mounted hydrogen storage system are usually in the shape of long cylinders, which are...
