Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a hydrogen power supply device for a two-wheeled vehicle. Background Technology

[0002] Most existing hydrogen-powered electric two-wheelers combine solid-state hydrogen storage devices with fuel cells to power the vehicles. During hydrogen release, the solid-state hydrogen storage device absorbs heat, and after a period of time, the temperature around the storage device decreases, thus slowing down the release rate and reducing the fuel cell's power output. Current solid-state hydrogen storage devices typically use heating elements to maintain the surrounding temperature and thus the release rate, ensuring stable power generation from the fuel cell. However, this method of adding heating elements increases structural complexity and parasitic power consumption. Furthermore, hydrogen fuel cells generate heat during the reaction process. To prevent the fuel cell from overheating, the fuel cell stack is usually placed in a well-ventilated location, relying on the cool airflow around the vehicle to dissipate the heat and prevent overheating.

[0003] Therefore, a thermal management system needs to be designed to directionally introduce the hot air generated by the fuel cell reaction into the hydrogen storage device to achieve waste heat recovery and reuse. By optimizing the structural layout of the hydrogen fuel cell and hydrogen storage device, the system structure can be simplified, parasitic power consumption can be avoided, the overall energy efficiency of the hydrogen energy system can be improved, and the efficient application of hydrogen-powered electric two-wheelers can be solved. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a hydrogen power supply device for two-wheeled vehicles, which can improve the overall energy efficiency of the hydrogen energy system by simplifying the system structure, avoiding parasitic power consumption.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a hydrogen power supply device for a two-wheeled vehicle, comprising a cylindrical and vertically arranged loading box, the loading box being divided into a hydrogen storage area and a fuel cell area in the same direction, the fuel cell area containing a hydrogen fuel cell, and the hydrogen storage area containing a hydrogen storage cylinder, the hydrogen storage cylinder being connected to the hydrogen inlet of the hydrogen fuel cell via a hydrogen delivery pipe; an air inlet is provided on the side of the loading box near the hydrogen storage area, and an exhaust outlet is provided on the side near the hydrogen fuel cell, the air inlet and exhaust outlet being diagonally distributed, an exhaust fan is provided on the loading box at the air inlet, and a through-flow air circulation path is formed between the exhaust fan, the air inlet and the exhaust outlet.

[0006] Because hydrogen storage tanks absorb heat during hydrogen release, the temperature around the tanks decreases over time, slowing down the release rate and reducing the fuel cell's power output. Therefore, a highly efficient closed-loop thermal management system is designed, dividing the hydrogen storage tanks and fuel cells into zones within the loading container. The hydrogen fuel cells, exhaust fans, and storage zones are aligned in the same direction. Airflow generated by the exhaust fans directly drives the storage zones through specific through-holes. The exhaust and inlet ports are diagonally distributed, forming a forced convection channel that penetrates the surface of the storage tank, effectively improving hydrogen release efficiency and ensuring stable power output from the fuel cell.

[0007] Furthermore, the loading box is provided with a loading box cover plate at the upper end, and the loading box cover plate has a accommodating opening in the middle for placing the hydrogen storage cylinder.

[0008] The loading box cover forms a closed structure by fitting with the upper end of the loading box. The central accommodating port adopts a limiting design that is adapted to the shape of the hydrogen storage bottle, which can realize the axial positioning and circumferential fixation of the hydrogen storage bottle. The upper end of the hydrogen storage bottle extends out of the cover plate, which facilitates the quick installation and removal of the hydrogen storage bottle.

[0009] Furthermore, one side of the exhaust fan is rotatably mounted to the air inlet facing the inner cavity of the loading box.

[0010] The exhaust fan adopts a single-sided rotatable connection structure, allowing the fan blades to rotate and adjust around the edge of the air inlet. This design achieves dynamic spatial adaptation during installation and operation: when installed in the confined space of a two-wheeled vehicle, the exhaust fan can be rotated clockwise to retract into the loading box cavity, reducing the overall size of the device and avoiding interference with the vehicle frame components; after installation, the fan is rotated counterclockwise to the working angle, at which point the fan outlet faces the center of the hydrogen storage area. While expanding the usable radial space of the hydrogen storage area, this structure solves the installation compatibility problem of compact power units in limited spaces, reserving structural redundancy for future upgrades to large-capacity hydrogen storage cylinders.

[0011] Furthermore, the loading box cover is provided with a first fixing hole on the side near the rotation center of the exhaust fan. When the exhaust fan rotates and is retracted into the inner cavity of the loading box, the exhaust fan can be connected and fixed to the first fixing hole by screws. The loading box cover is provided with a second fixing hole on the side away from the rotation center of the exhaust fan. When the exhaust fan rotates and extends out of the air inlet, the exhaust fan can be connected and fixed to the second fixing hole by screws.

[0012] The dual fixing hole design enables multi-angle fixing of the exhaust fan. The first fixing hole is used to fix the exhaust fan when it rotates into the loading box. After the supply device is installed on the two-wheeled vehicle, the screws are loosened at the first fixing hole, the exhaust fan is rotated outward to the outside, and the position of the exhaust fan is fixed by the second mounting hole.

[0013] Furthermore, the loading box cover is provided with clamps for securing the hydrogen storage cylinder.

[0014] Furthermore, the clamp is an annular fixing clamp with an opening on one side, and the annular fixing clamp is fixed to the loading box cover plate away from the opening side.

[0015] The clamps further enhance the stability of the hydrogen storage cylinders, preventing loosening of connections or displacement due to vibration during vehicle operation, thus ensuring the safety and reliability of hydrogen supply.

[0016] Furthermore, the fuel cell area is vertically equipped with a top and bottom plate, a lower support plate, and a front cover plate of the fuel cell stack. The hydrogen fuel cell is mounted on the front cover plate of the fuel cell stack on one side. The lower support plate is connected to the bottom end plate of the hydrogen fuel cell stack, and the top and bottom plates are connected to the top end plate of the hydrogen fuel cell stack. A lower space is formed between the lower support plate, the front cover plate of the fuel cell stack, and the bottom end plate of the hydrogen fuel cell stack, and an upper space is formed between the top and bottom plates, the front cover plate of the fuel cell stack, and the top end plate of the hydrogen fuel cell stack. The front cover plate of the fuel cell stack has ventilation holes adapted to the exhaust vent. The hydrogen fuel cell is installed directly opposite the exhaust fan outlet side through the top and bottom plates, the lower support plate, and the front cover plate of the fuel cell stack.

[0017] The structural design of the lower support plate, top and bottom plates, and front cover plate of the fuel cell stack provides stable support for the hydrogen fuel cell while creating upper and lower spaces for arranging pipelines and auxiliary equipment, thus optimizing the internal space layout.

[0018] Furthermore, a top cover plate is provided above the top and bottom plates and the front cover plate of the fuel cell stack, and the top cover plate and the inner wall of the loading box form a control area for installing the control panel.

[0019] Furthermore, the loading box is equipped with a ventilation and protective net at the exhaust vent.

[0020] Furthermore, the hydrogen storage cylinder is equipped with a three-way pressure reducing valve. The hydrogen outlet of the pressure reducing valve is connected to the gas inlet of the hydrogen fuel cell via a hydrogen supply pipe and a first solenoid valve, and the gas outlet of the hydrogen fuel cell is connected to a second solenoid valve.

[0026] The present invention will be further described in detail below with reference to the embodiments.

[0027] In practical implementation: such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a hydrogen power supply device for a two-wheeled vehicle includes a cylindrical, vertically arranged loading box 1. The loading box 1 is divided into a hydrogen storage area 2 and a fuel cell area 3 in the same direction. A hydrogen fuel cell 4 is installed in the fuel cell area 3, and a hydrogen storage cylinder 5 is installed in the hydrogen storage area 2. Since the hydrogen storage cylinder 5 absorbs heat during hydrogen release, the temperature around the cylinder 5 decreases after a period of time, thus reducing the hydrogen release rate and the power generation of the fuel cell. The hydrogen storage cylinder 5 is connected to the hydrogen inlet of the hydrogen fuel cell 4 via a hydrogen supply pipe. An air inlet 11 is provided on the side of the loading box 1 near the hydrogen storage area 2, and an exhaust outlet 12 is provided on the side near the hydrogen fuel cell 4. The air inlet 11 and exhaust outlet 12 are diagonally distributed. An exhaust fan 13 is provided at the air inlet 11, and a through-flow air circulation path is formed between the exhaust fan 13, the air inlet 11, and the exhaust outlet 12. The hydrogen storage cylinder 5 and the fuel cell are divided into zones within the loading box 1. The hydrogen fuel cell 4, the exhaust fan 13, and the hydrogen storage zone 2 are arranged in the same direction. The airflow generated by the exhaust fan 13 drives the hydrogen storage zone 2 directly through specific through holes. The exhaust port 12 and the air inlet 11 are diagonally distributed to form a forced convection channel that penetrates the surface of the hydrogen storage cylinder 5, which effectively improves the hydrogen release efficiency and ensures stable power output from the fuel cell.

[0028] The loading box 1 has a loading box cover 15 at its upper end, and the loading box cover 15 has a receiving opening 151 in the middle for placing the hydrogen storage cylinder 5. The loading box cover 15 forms a closed structure by cooperating with the upper end of the loading box 1. The middle receiving opening 151 adopts a limiting design that is adapted to the shape of the hydrogen storage cylinder 5, which can realize the axial positioning and circumferential fixation of the hydrogen storage cylinder 5. The upper end of the hydrogen storage cylinder 5 extends out of the cover plate, which facilitates the quick installation and removal of the hydrogen storage cylinder 5.

[0029] During implementation, one side of the exhaust fan 13 is rotatably mounted on the air inlet 11 within the loading box 1. The exhaust fan 13 adopts a single-sided rotatable connection structure, allowing the fan blades to rotate and adjust around the edge of the air inlet 11. This design achieves dynamic spatial adaptation between the installation process and the working state: when installed in the narrow space of a two-wheeled vehicle, the exhaust fan 13 can be rotated clockwise to be stored inside the loading box 1, reducing the overall size of the device and avoiding interference with the vehicle frame components; after installation, the fan is rotated counterclockwise to the working angle, at which point the fan outlet faces the center of the hydrogen storage area 2. While expanding the usable radial space of the hydrogen storage area 2, this structure solves the installation compatibility problem of compact power units in limited spaces, reserving structural redundancy for subsequent upgrades to large-capacity hydrogen storage cylinders 5.

[0030] like Figure 5 As shown, the cover plate of the loading box 1 has a first fixing hole 152 on the side near the rotation center of the exhaust fan 13. When the exhaust fan 13 rotates and is stored in the inner cavity of the loading box 1, the exhaust fan 13 can be connected and fixed to the first fixing hole 152 by screws. The cover plate of the loading box 1 has a second fixing hole 153 on the side away from the rotation center of the exhaust fan 13. When the exhaust fan 13 rotates and extends out of the air inlet 11, the exhaust fan 13 can be connected and fixed to the second fixing hole 153 by screws.

[0031] The dual-fixing-hole design enables multi-angle fixing of the exhaust fan 13. The first fixing hole 152 is positioned to fix the exhaust fan 13 when it rotates into the loading box 1. After the supply device is installed on the two-wheeled vehicle, the screws are loosened at the first fixing hole 152, and the exhaust fan 13 is rotated outwards to the outside. The second mounting hole then fixes the position of the exhaust fan 13. Simultaneously, by improving the structural layout of the supply device to accommodate the space of the two-wheeled vehicle, and considering the rotatable design of the exhaust fan 13, the space in the hydrogen storage area of ​​the supply device can be prevented from shrinking due to interference from the exhaust fan 13, thus allowing for the placement of a larger capacity hydrogen storage cylinder 5.

[0032] The cover plate is equipped with a clamp for securing the hydrogen storage cylinder 5. The clamp is an annular fixing clip 154 ​​with an opening on one side, which is fixed to the cover plate away from the opening side. The opening side of the annular fixing clip 154 ​​can be secured by bolts, nuts, or clips. Furthermore, the annular fixing clip 154 ​​is located on the upper side of the loading tank cover plate 15 for convenient installation and replacement of the hydrogen storage cylinder 5.

[0033] The hydrogen storage cylinder 5 is equipped with a three-way pressure reducing valve. The hydrogen outlet of the pressure reducing valve is connected to the gas inlet of the hydrogen fuel cell 4 through a hydrogen supply pipe and a first solenoid valve 6. The gas outlet of the hydrogen fuel cell 4 is connected to a second solenoid valve 7.

[0034] Within the fuel cell area 3, a top and bottom plate 31, a lower support plate 32, and a front cover plate 33 of the fuel cell stack are vertically arranged. One side of the hydrogen fuel cell 4 is mounted on the front cover plate 33. The lower support plate 32 is connected to the bottom end plate of the hydrogen fuel cell stack, and the top and bottom plate 31 is connected to the top end plate of the hydrogen fuel cell stack. A lower space is formed between the lower support plate 32, the front cover plate 33, and the bottom end plate of the hydrogen fuel cell stack. This lower space accommodates and protects the outlet end of the hydrogen fuel cell 4. The second solenoid valve 7 and exhaust pipe are connected to the gas end; an upper space is formed between the top and bottom plates 31, the front cover plate 33 of the fuel cell stack, and the top plate of the hydrogen fuel cell stack 4. The upper space accommodates and protects the air inlet of the hydrogen fuel cell 4 and the first solenoid valve 6 connected to the air inlet; the front cover plate 33 of the fuel cell stack has ventilation holes adapted to the exhaust port 12. The hydrogen fuel cell 4 is installed on the exhaust fan 13 outlet side directly opposite to the top and bottom plates 31, the lower support plate 32, and the front cover plate 33 of the fuel cell stack. The structural design of the lower support plate 32, the top and bottom plates 31, and the front cover plate 33 of the fuel cell stack provides stable support for the hydrogen fuel cell 4 while forming an upper and lower space for arranging pipelines and auxiliary equipment, thus optimizing the internal space layout.

[0035] A top cover plate 34 is provided above the top and bottom plates 31 and the front cover plate 33 of the fuel cell stack. The top cover plate 34 and the inner wall of the loading box 1 form a control area for installing the control board. The FCCU control board is placed in the control area.

[0036] The loading box 1 is equipped with a ventilation and protective net 14 at the exhaust vent 12.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
