Highly integrated passenger car hydrogen cylinder group structure

Abstract

The invention relates to the technical field of a hydrogen cylinder group installation mode, in particular to a highly integrated passenger car hydrogen cylinder group structure. The highly integratedpassenger car hydrogen cylinder group structure includes a car frame and a hydrogen cylinder body. A framework mechanism is arranged at the bottom of the middle part of the car frame. A fixed mechanism includes a fixed plate, lightening holes, fixed screws, a rubber blanket, a movable pressing plate and connecting screws. The fixed screws are mounted at the rear end of the fixed plate, the fixedmechanism is internally provided with thehydrogen cylinder body. According to the highly integrated passenger car hydrogen cylinder group structure, the improved hydrogen cylinder group realizes the possibility of a large range of a small car without occupying layout space, and the design basis for miniaturization of a fuel cell passenger car is provided, and compared with the traditional layout mode of a hydrogen cylinder group, hydrogen storage capacity is greatly improved, the driving range of a whole car is improved, the NEDC driving range of the whole car reaches more than 800km, and useneeds of people are effectively met.

Description

technical field [0001] The invention relates to the technical field of installation methods of hydrogen cylinders, in particular to a highly integrated passenger car hydrogen cylinder structure. Background technique [0002] From around 2010 to 2015, fuel cell engines achieved commercial breakthroughs. Internationally renowned automakers and fuel cell companies focused on commercial development, and made a key breakthrough in 2015, thus fuel cell engines entered the commercialization stage; and then promoted Fuel cell engine-powered vehicles are developing rapidly. When hydrogen fuel cell engines are applied to vehicle power, in addition to the inherent characteristics of zero emissions, the remarkable advantages of fast fuel filling are recognized as the ultimate solution for new energy vehicles. However, due to the large space occupied by the hydrogen cylinder group, the installation of hydrogen cylinders on traditional vehicle platforms is more limited by the layout, and ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a highly integrated structure of hydrogen cylinders for passenger cars, which solves the problem that most of the current hydrogen energy vehicles adopt the original fuel vehicle platform, and most of the hydrogen cylinders are arranged in a layout. At the rear of the car body, the axle load of the car body is unreasonable. The performance of the original front-wheel-drive model was developed. The hydrogen energy group arranged in the rear suspension has potential safety hazards when the rear collision invades. Most of the hydrogen cylinder groups are installed in a distributed manner, which is costly and expensive. Maintenance is inconvenient. The hydrogen cylinder valve group is generally arranged on the side of the vehicle body without safety protection. The trunk space is occupied by the hydrogen cylinder, resulting in a significant reduction in the trunk space, which cannot meet people's needs.
