Description

Technical Field

[0001] This utility model relates to the field of hydrogen energy supply systems, and in particular to a vehicle-mounted hydrogen supply system with a modular structure connection. Background Technology

[0002] Currently, hydrogen storage cylinders in on-board hydrogen supply systems are typically installed in two ways: horizontal and vertical.

[0003] The vertical arrangement involves placing the hydrogen storage cylinders along their length in a vertical and horizontal direction, which saves space in terms of height.

[0004] However, the frame surrounding each vertical hydrogen storage cylinder needs to be strong enough to ensure the safety of each cylinder, making the frame design complex and the arrangement of multiple cylinders rather dispersed. When the vehicle encounters bumpy road conditions, the stability of the hydrogen cylinders is not high.

[0005] In addition, hydrogen storage cylinders are not easy to install in a vertical system frame. They are usually installed horizontally and then the whole system is flipped. If a large number of hydrogen storage cylinders are required, special flipping fixtures are needed to change the hydrogen supply system from horizontal to vertical. The flipping fixtures are large in size and costly. In many cases, the flipping fixtures are not suitable for maintenance of the hydrogen supply system, which is not conducive to the work.

[0006] If a hydrogen storage cylinder in the hydrogen supply system needs to be disassembled, the vertical hydrogen supply system has limited space and is not easy to operate. It usually cannot be disassembled directly. Other hydrogen storage cylinders in the surrounding area must be disassembled first to leave enough operating space before the hydrogen storage cylinder can be disassembled. The process is cumbersome and time-consuming.

[0007] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0008] The purpose of this invention is to provide a vehicle-mounted hydrogen supply system with a modular structure to address the shortcomings of existing technologies.

[0009] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0010] A vehicle-mounted hydrogen supply system with a modular structure includes several hydrogen supply modules. Each hydrogen supply module includes a hydrogen storage frame, several bottle holders at the bottom of the hydrogen storage frame, and several hydrogen storage bottles installed inside the hydrogen storage frame via the bottle holders. The bodies of the hydrogen storage bottles are fixed to the hydrogen storage frame by straps, and a pressure plate is provided at the top of the hydrogen storage bottles.

[0011] The pressure plate includes a base plate, with a clearance opening in the middle for the inlet / outlet of the hydrogen storage cylinder to extend out. The two sides of the base plate are respectively connected and fixed to the hydrogen storage frame through a connecting plate. Several positioning plates are provided on the bottom surface of the base plate, and the positioning plates have an arc that adapts to the top of the hydrogen storage cylinder.

[0012] Furthermore, the bottom of the hydrogen storage frame is provided with container corner fittings, and the hydrogen supply module is connected through the container corner fittings. A horizontal baffle is provided in the middle of the hydrogen storage frame, and the horizontal baffle is connected to the hydrogen storage frame through a detachable structure. A lifting nut is provided at the top of the hydrogen storage frame.

[0013] Furthermore, the inlet / outlet of the hydrogen storage cylinder is connected via a pipeline assembly, which includes a hydrogen delivery pipeline and a pipeline connector for connecting the hydrogen delivery pipeline.

[0014] Furthermore, the hydrogen storage frame of the hydrogen supply module is provided with bolt holes, and buffer pads are provided between the hydrogen storage frames of adjacent hydrogen supply modules. They are connected by bolt assemblies and bolt holes to form an on-board hydrogen supply system.

[0015] Furthermore, the bolt holes are located on the side of the hydrogen storage frame, and the bolt assembly includes a stud and a nut.

[0016] In summary, this utility model has the following beneficial effects:

[0017] By adopting a modular connection structure, several hydrogen storage cylinders can be installed in the vertical hydrogen supply module as needed, and then the hydrogen supply module can be connected as a whole. Thus, the assembly of a large-capacity vertical vehicle-mounted hydrogen supply system can be completed without additional flipping tooling.

[0018] By installing base supports, straps, and pressure plates at the bottom, middle, and top of the hydrogen storage cylinder for fixing, the cylinder can be positioned in all directions, effectively improving its stability.

[0019] The hydrogen supply module is connected via a detachable bolt assembly, facilitating future maintenance and upkeep. Attached Figure Description
