Problems solved by technology

At this stage, the structure of the bottle mouth of the hydrogen fuel storage device is too complicated, and it is inconvenient to replace. Most of the bottle mouth pressure reducing valves and pressure reducing devices are replaced together, which greatly increases the cost. Therefore, a safe replacement is required. A hydrogen storage device with a simple structure and low cost, as well as a hydrogen supply system that can be matched with the device, can reduce costs while ensuring safety

Abstract

The invention discloses a safety hydrogen storage device of a hydrogen energy booster vehicle and a hydrogen supply system thereof. The safety hydrogen storage device comprises a hydrogen storage bottle and a valve arranged at the mouth of the hydrogen storage bottle. The hydrogen storage bottle sequentially comprises a inner container, a winding layer and an outer shell from inside to outside. The valve is a top-opening valve. The valve comprises a valve body, a top column, bulges, a spring, an air nozzle, an elastic pressurizing ring, a vent hole and a connecting groove. The valve body is ina cap shape and is suitable for being connected with a hydrogen cylinder, and a groove is arranged inside the valve body. The top column penetrates through the valve body and is suitable for moving up and down in the valve body. The upper part of the top column is provided with a circle of bulges, and the bulges are arranged in the grooves in the valve body. The spring is suitable for providing upward moving force for the top column. The air nozzle is matched with the bottom of the top column, and the top column is suitable for opening the air nozzle when moving downwards. The elastic pressurizing ring is arranged at the lower part of the air nozzle in a sleeving manner. The center of the top column is provided with the vent hole suitable for gas to pass through. The top of the valve bodyis provided with the connecting groove. According to the safety hydrogen storage device of the hydrogen energy booster vehicle and the hydrogen supply system thereof, by arranging a top-opening typevalve mechanism and a rebound and protection structure, the structure is simplified, and meanwhile, the safety is ensured; and a vertical z-shaped air nozzle is arranged, the sealing area of the air nozzle can be effectively increased, the sealing performance is improved, and the safety is further improved.

Description

technical field [0001] The invention relates to the technical field of hydrogen storage and hydrogen supply, in particular to a safe hydrogen storage device and a hydrogen supply system for a hydrogen energy power-assisted vehicle. Background technique [0002] As a convenient and common means of transportation, shared bicycles have been greatly recognized by the market to meet people's needs for one to three kilometers, but the bicycles themselves still have their limitations, such as headwinds, it will be very laborious when going uphill, and riding for a long time It will be very tired, and it cannot solve the travel needs of longer distances well. Therefore, mopeds are needed to better meet people's needs. [0003] With the increasing population and increasing energy consumption, the problem of energy shortage is gradually increasing, and the development and use of green energy has become a hot spot of global concern. A hydrogen fuel cell is a device that uses hydrogen ...
