Top and bottom transverse vehicle-mounted hydrogen system assembly

Abstract

This utility model discloses a horizontally mounted vehicle hydrogen system assembly, comprising: a lower hydrogen cylinder assembly fixed below the vehicle frame beam, an upper hydrogen cylinder assembly fixed above the vehicle frame beam, and an electrical system fixed above the upper hydrogen cylinder assembly. Each hydrogen cylinder in the assembly is horizontally positioned with its orientation lateral to lateral. The lower hydrogen cylinder assembly is installed in a lower square frame, the upper hydrogen cylinder assembly is installed in an upper square frame, and the electrical system is installed in a square electrical frame. The bottom of the electrical frame is fixed to the top of the upper square frame with bolts. This horizontally mounted vehicle hydrogen system assembly fixes the lower hydrogen cylinder assembly below the vehicle frame beam, the upper hydrogen cylinder assembly above the vehicle frame beam, and the electrical system above the upper hydrogen cylinder assembly. This configuration significantly reduces the height of the vehicle hydrogen system, ensuring that it does not obstruct the rearview mirrors on both sides of the driver's cab. Furthermore, because the hydrogen cylinders are horizontally positioned, it also significantly reduces the vehicle's length requirements.

Description

Technical Field

[0001] This utility model relates to the field of on-board hydrogen supply systems for hydrogen fuel cell vehicles, specifically to an upper and lower horizontally mounted on-board hydrogen system assembly. Background Technology

[0002] Fuel cell vehicles are new energy electric vehicles powered by electricity generated by an onboard fuel cell device. Among various new energy vehicles, they are considered an important direction for the sustainable development of the future automotive industry due to their advantages such as zero emissions, high efficiency, diversified fuel sources, and renewable energy, which helps to solve global energy problems and climate change issues. The onboard hydrogen supply system is the device that provides hydrogen to the fuel cell vehicle, and it generally consists of a frame, skin, and piping system.

[0003] Currently, the conventional layouts of onboard hydrogen systems for tractor trucks are: 1) Front-rear configuration: All hydrogen cylinders in the onboard hydrogen system are stacked horizontally on the back of the front of the truck. In this configuration, the height of the onboard hydrogen system is approximately 2 meters. A 2-meter-high onboard hydrogen system will obstruct the driver's field of vision through the side mirrors, limiting the driver's field of vision and posing a potential safety hazard. 2) Lower side-mounted configuration: This requires the axis of the hydrogen cylinder to be aligned with the length of the vehicle body, inevitably increasing the overall length of the vehicle, which is not suitable for customers' small vehicles. Utility Model Content

The two upper frame bottom beams rest on the left and right sides of the main frame beam. The bottoms of the two upper frame columns on each side are welded to the ends of the corresponding upper frame bottom beams. Each upper frame bottom beam has a large ear plate and a small ear plate at its front and rear ends, respectively. Each large ear plate is fixed to the outer wall of the main frame beam and the outer wall of the upper frame bottom beam with bolts. Each small ear plate rests on... The large ear plate is placed on the location and fixed to the small ear plate with bolts. The small ear plate is fixed to the outer wall of the upper frame bottom beam with bolts passing through the bottom of the upper frame column. On the left and right sides of the upper square frame, there is a support column for supporting the electrical frame. The bottom of the two support columns is welded to the upper frame bottom beam on the side. The upper frame bottom beam has an arc-shaped notch for positioning the hydrogen cylinder. An arc-shaped saddle is welded to each arc-shaped notch. The hydrogen cylinder is placed on the arc-shaped saddle.

This arrangement greatly reduces the height of the vehicle hydrogen system, so that the vehicle hydrogen system does not obstruct the rearview mirrors on both sides of the cab. In addition, since the hydrogen tanks are placed in a left-right orientation, the requirements for vehicle length are also greatly reduced. Attached Figure Description
