Description

Technical Field

[0001] This utility model belongs to the field of automobile manufacturing, and specifically relates to a side-mounted hydrogen storage system device for hydrogen fuel cell vehicles. Background Technology

[0002] Hydrogen energy, as part of the national strategy, boasts high energy density, environmental friendliness, renewability, and flexible energy storage, making it particularly suitable for heavy-duty, long-distance, and low-temperature environments in commercial vehicles. It makes a significant contribution to reducing dependence on oil and improving energy security. Currently, hydrogen storage systems in most hydrogen fuel cell vehicles are located on the rear beam of the cab. If this design were applied to light trucks, it would encroach on cargo space, significantly reducing the loading capacity and lowering the transport efficiency of light trucks. Utility Model Content

[0003] This utility model is specifically designed for newly developed light-duty hydrogen fuel cell trucks, featuring a side-mounted system that integrates hydrogen storage, supply, and refueling. The hydrogen supply system is highly integrated and mounted on the chassis on both sides of the frame, with a gas cylinder located on each side and connected in series via pipelines. This solves the problem of occupying cargo box space. The specific technical solution is as follows:

[0004] A side-mounted hydrogen storage system for a hydrogen fuel cell vehicle includes two gas cylinders and a mounting frame. The mounting frame is symmetrically equipped with gas cylinder support arms, gas cylinder straps, and protective covers. The two gas cylinders are placed inside the gas cylinder support arms and secured with the gas cylinder straps. The protective covers cover the gas cylinders on the outside of the frame. Mounting holes are provided on the outer side of the gas cylinder support arms to mount the entire hydrogen storage system on the chassis on both sides of the vehicle frame. The two gas cylinders are connected in series via high-pressure rigid pipes. One end of the high-pressure rigid pipe is equipped with a hydrogen filling port and a one-way valve. Two T-junctions are installed on the high-pressure rigid pipes to input hydrogen into the two gas cylinders. The hydrogen outlet pipes of the two gas cylinders are connected in sequence to a filter and a manual pressure reducing valve before reaching the hydrogen supply hose.

[0005] Furthermore, each gas cylinder is equipped with a hydrogen concentration sensor and a cylinder valve.

[0006] Furthermore, a hydrogen controller is electrically connected to a hydrogen concentration sensor, a one-way valve, and a gas cylinder valve, which can control the opening and closing of the valves based on the hydrogen status returned by the sensor.

[0007] This utility model is applicable to the side-mounted arrangement of hydrogen storage systems in commercial vehicles, distributed on both sides of the chassis frame. All hydrogen storage, hydrogen supply, and hydrogen refueling systems are integrated within the frame. The side-mounted gas cylinder arrangement does not compress the vehicle compartment space and meets the transportation space requirements. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figure 1-2 As shown, a side-mounted hydrogen storage system for a hydrogen fuel cell vehicle includes two gas cylinders and a mounting frame. The mounting frame is symmetrically equipped with gas cylinder support arms, gas cylinder straps, and protective covers. The two gas cylinders are placed inside the gas cylinder support arms and fixed with the gas cylinder straps. The protective covers cover the gas cylinders on the outside of the frame. Mounting holes are provided on the outer side of the gas cylinder support arms to mount the entire hydrogen storage system on the chassis on both sides of the vehicle frame. The two gas cylinders are connected in series via high-pressure rigid pipes. One end of the high-pressure rigid pipe is equipped with a hydrogen filling port and a one-way valve. Two T-junctions are installed on the high-pressure rigid pipes to input hydrogen into the two gas cylinders. The hydrogen outlet pipes of the two gas cylinders are connected in sequence to a filter and a manual pressure reducing valve before reaching the hydrogen supply hose.

[0016] Each gas cylinder is equipped with a hydrogen concentration sensor and a cylinder valve. A hydrogen controller is electrically connected to the hydrogen concentration sensor, check valve, and cylinder valve. It can control the valve's opening and closing based on the hydrogen status reported by the sensor. The electrical control configuration is as follows: Figure 4 As shown.
