Arrangement structure of multi-layer CNG cylinders

Abstract

The invention relates to an arrangement structure of multi-layer CNG cylinders. The arrangement structure comprises an upper-layer gas cylinder installation assembly, a middle-layer gas cylinder installation assembly and a lower-layer gas cylinder installation assembly, all of which are sequentially arranged from the top to the bottom. The upper-layer gas cylinder installation assembly comprises gas cylinder hanging supports, upper-layer brackets and U-shaped bolt tightening belts. The middle-layer gas cylinder installation assembly comprises middle-layer gas cylinder brackets and middle-layer gas cylinder tightening belts. The lower-layer gas cylinder installation assembly comprises lower-layer gas cylinder brackets and lower-layer gas cylinder tightening belts. The arrangement structure of multi-layer CNG cylinders has following beneficial effects: according to cylindrical features of CNG gas cylinders, space is utilized in an alternating mode in order to achieve three-layer arrangement of CNG gas cylinders; space is utilized to the maximum so that occupation space of a luggage compartment is decreased; and a market requirement is satisfied.

Description

technical field [0001] The invention relates to the technical field of passenger cars, in particular to a multilayer CNG cylinder arrangement structure. Background technique [0002] At present, with the ever-increasing competitive pressure in the road passenger transport market and the continuous rise of the logistics market, it has become a mainstream trend to carry goods by bus, which requires a larger cargo-carrying capacity for passenger cars. However, with the continuous increase of domestic oil prices, clean energy buses such as CNG are also emerging. At present, the mainstream road buses arrange the gas cylinders in the luggage compartment between the front axle and the rear axle. Due to the restriction on the height of the vehicle in the standard, according to the traditional gas cylinder arrangement method, only two layers of CNG cylinders can be arranged in the luggage compartment of any kind of passenger car at most, which leads to a certain waste of space and...

AI Technical Summary

Problems solved by technology

Due to the limitation on the height of the vehicle in the standard, according to the traditional gas cylinder arrangement method, only two layers of CNG cylinders can be arranged in the luggage compartment of any kind of passenger car at most, which leads to a certain waste of space and takes up a lot of luggage cabin space

And as far as the current technology is concerned, too large a division of the gas cylinder compartment will lead to insufficient strength of the whole vehicle. Therefore, in the mainstream form, one gas cylinder compartment can only hold up to 8 gas cylinders, and more gas cylinders require two gas cylinder compartments. Arrangement, not only leads to a greater waste of space but also requires the waste of accessories such as the corresponding hatch mechanism
