Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a power supply device for a hydrogen energy two-wheeled vehicle. Background Art

[0002] Most of the existing hydrogen-powered electric two-wheeled vehicles are powered by a combination of a solid-state hydrogen storage device and a fuel cell. The solid-state hydrogen storage device needs to absorb heat during the hydrogen release process. After a period of hydrogen release, the temperature around the hydrogen storage device will decrease, thereby reducing the speed of hydrogen release and reducing the power generation of the fuel cell. The existing solid-state hydrogen storage device is generally provided with a heating plate to maintain the temperature around the hydrogen storage device to maintain the speed of hydrogen release and ensure the stability of the power generation of the fuel cell. However, this method of adding a heating plate increases the complexity of the structure and increases the parasitic power consumption; however, the hydrogen fuel cell generates heat during the reaction process. In order to avoid the excessive temperature of the fuel cell, it is usually necessary to set the fuel cell reaction stack in a well-ventilated position, so as to rely on the cold wind around the two-wheeled vehicle to take away the heat of the fuel cell when the two-wheeled vehicle is walking, so as to avoid overheating of the fuel cell. Therefore, the utility model provides a hydrogen-powered two-wheeled vehicle power supply device that can use the hot air generated by the fuel cell to heat the hydrogen storage device. In this way, there is no need to increase the complexity of the structure or the parasitic power consumption. Utility Model Content

[0003] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is: how to provide a hydrogen two-wheeled vehicle power supply device with a simple structural design, reduced parasitic power consumption, and utilizing hot air from a hydrogen fuel cell.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A power supply device for a hydrogen-powered two-wheeled vehicle comprises a loading cylinder which is cylindrical in shape and vertically arranged, wherein a partition arranged vertically is provided in the loading cylinder and the loading cylinder is divided into a fuel cell area and a hydrogen storage area; a hydrogen fuel cell is provided in the fuel cell area and vertically mounted on the partition, and the partition has a through hole arranged throughly, so that an exhaust fan of the hydrogen fuel cell can enter the hydrogen storage area; a fixing groove extending upward is provided at the bottom of the hydrogen storage area, a hydrogen storage bottle is inserted in the fixing groove, the diameter of the hydrogen storage bottle matches the inner diameter of the fixing groove, and the height of the hydrogen storage bottle matches the height of the loading cylinder; an air inlet is arranged throughly on a side of the fuel cell area away from the hydrogen storage area, and an exhaust outlet is uniformly arranged on a side of the hydrogen storage area close to the hydrogen storage bottle, and the exhaust outlet and the air inlet are orthogonally distributed in space, and the hydrogen storage bottle is connected to the hydrogen inlet of the hydrogen fuel cell through a hydrogen transmission pipe.

[0006] Since the hydrogen storage bottle needs to absorb heat during the hydrogen discharge process, after a period of hydrogen discharge, the temperature around the hydrogen storage bottle will decrease, thereby reducing the speed of hydrogen discharge and reducing the power generation of the fuel cell. Therefore, the above structure is adopted, and the hydrogen storage bottle is inserted and fixed in the fixed groove, so that it can remain stable during the driving of the two-wheeled vehicle, ensuring the stable supply of hydrogen; and because the exhaust fan of the hydrogen fuel cell enters the hydrogen storage area through the through hole, when the hydrogen fuel cell works normally, the generated hot air is discharged into the hydrogen storage area through the exhaust fan. Since the exhaust port is located on the side close to the hydrogen storage bottle and is orthogonal to the air inlet, the hot air entering the hydrogen storage area will definitely pass through the hydrogen storage bottle when it is discharged through the exhaust port. At this time, the hot air can supply heat to the hydrogen storage bottle by heat transfer, so that the hydrogen storage bottle is maintained at a suitable temperature to improve the hydrogen discharge efficiency of the hydrogen storage bottle and ensure the stable power supply of the hydrogen fuel cell. Another advantage of the orthogonal distribution of the exhaust port and the air inlet is that the time the hot air stays in the hydrogen storage area can be extended, which is beneficial to extending the heating time and improving the utilization efficiency of the hot air. This method of using the hot air generated by the fuel cell to heat the hydrogen storage bottle does not increase parasitic power consumption or structural complexity, which is beneficial to improving the energy utilization rate of the hydrogen fuel cell stack.

[0007] Furthermore, a support plate is disposed transversely in the fuel cell area, the support plate is mounted above the hydrogen fuel cell by screws, a lithium battery is mounted on the support plate, and the lithium battery is connected in parallel with the hydrogen fuel cell.

[0008] When a two-wheeled vehicle is running in winter or in low-temperature areas, due to the low temperature, the hydrogen storage bottle's hydrogen release efficiency is not high when the two-wheeled vehicle is started, which may cause the electricity generated by the hydrogen fuel cell to be insufficient to maintain the normal operation of the two-wheeled vehicle. By connecting a lithium battery in parallel, the two-wheeled vehicle can be started quickly in a low-temperature environment.

[0009] Furthermore, a cover plate is installed on the upper end of the loading cylinder by screws, and a clearance hole is provided through the side of the cover plate facing the hydrogen storage area, and the clearance hole is arranged opposite to the hydrogen storage bottle; a handle for easy carrying is installed on the side of the cover plate facing the fuel cell area.

[0010] In this way, the power supply device can be easily replaced and carried through the handle, and the positioning hole and the hydrogen storage bottle are arranged opposite to each other, which is beneficial for an external hydrogenation device to hydrogenate the hydrogen storage bottle.

[0011] Furthermore, a three-way pressure reducing valve is provided on the hydrogen storage bottle, and the pressure reducing valve just passes through the clearance hole, and the hydrogen outlet end of the pressure reducing valve is connected to the air inlet end of the hydrogen fuel cell through a hydrogen transmission pipe.

[0012] In this way, the pressure during output or hydrogenation can be reduced through the pressure reducing valve, which is helpful to ensure safe use.

[0013] Furthermore, the cover plate is also provided with a current output interface and a CAN interface.

[0014] Furthermore, a dust-proof net is provided on the air inlet.

[0015] In this way, impurities such as dust can be prevented from entering with the air and blocking the air flow path of the hydrogen fuel cell, which is beneficial to extending the service life of the hydrogen fuel cell.

[0016] Furthermore, a layer of thermal insulation film is laid on the inner wall of the hydrogen storage area.

[0017] In this way, heat loss can be reduced and as much heat as possible from the fuel cell can be used to heat the hydrogen storage bottle.

[0018] In summary, the utility model has the advantages of simple and reasonable structural design, reduced parasitic power consumption and structural complexity, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be further described in detail below in conjunction with the embodiments.

[0025] A hydrogen two-wheel vehicle power supply device, such as Figure 1 to Figure 5As shown, it includes a loading cylinder 1 which is cylindrical in shape and vertically arranged, and a vertically arranged partition is provided in the loading cylinder 1, and the loading cylinder 1 is divided into a fuel cell area 11 and a hydrogen storage area 12; a hydrogen fuel cell 8 is provided in the fuel cell area 11 and vertically installed on the partition, and the partition has a through hole arranged through, so that the exhaust fan of the hydrogen fuel cell enters the hydrogen storage area 12; the bottom of the hydrogen storage area 12 has a fixing groove 121 extending upward, and a hydrogen storage bottle is inserted in the fixing groove 121 2, the diameter of the hydrogen storage bottle 2 matches the inner diameter of the fixing groove 121, and the height of the hydrogen storage bottle 2 matches the height of the loading cylinder 1; the fuel cell area 11 has an air inlet 111 disposed through it on the side away from the hydrogen storage area 12, and the hydrogen storage area 12 has an evenly distributed exhaust port 122 on the side close to the hydrogen storage bottle 2, and the exhaust port 122 is orthogonally distributed with the air inlet 111 in space, and the hydrogen storage bottle is connected to the hydrogen inlet of the hydrogen fuel cell 8 through a hydrogen delivery pipe. A layer of thermal insulation film is laid on the inner wall of the hydrogen storage area 12.

[0026] Since the hydrogen storage bottle needs to absorb heat during the hydrogen discharge process, after a period of hydrogen discharge, the temperature around the hydrogen storage bottle will decrease, thereby reducing the speed of hydrogen discharge and reducing the power generation of the fuel cell. Therefore, the above structure is adopted, and the hydrogen storage bottle is inserted and fixed in the fixed groove, so that it can remain stable during the driving of the two-wheeled vehicle, ensuring the stable supply of hydrogen; and because the exhaust fan of the hydrogen fuel cell enters the hydrogen storage area through the through hole, when the hydrogen fuel cell works normally, the generated hot air is discharged into the hydrogen storage area through the exhaust fan. Since the exhaust port is located on the side close to the hydrogen storage bottle and is orthogonal to the air inlet, the hot air entering the hydrogen storage area will definitely pass through the hydrogen storage bottle when it is discharged through the exhaust port. At this time, the hot air can supply heat to the hydrogen storage bottle by heat transfer, so that the hydrogen storage bottle is maintained at a suitable temperature to improve the hydrogen discharge efficiency of the hydrogen storage bottle and ensure the stable power supply of the hydrogen fuel cell. Another advantage of the orthogonal distribution of the exhaust port and the air inlet is that the time the hot air stays in the hydrogen storage area can be extended, which is beneficial to extending the heating time and improving the utilization efficiency of the hot air. This method of using the hot air generated by the fuel cell to heat the hydrogen storage bottle does not increase parasitic power consumption or structural complexity, which is beneficial to improving the energy utilization rate of the hydrogen fuel cell stack.

[0027] like Figure 4 and Figure 5 As shown, in order to facilitate the rapid starting of a two-wheeled vehicle in winter, a support plate is horizontally arranged in the fuel cell area 11, and the support plate is installed above the hydrogen fuel cell 8 by screws. A lithium battery 3 is installed on the support plate, and the lithium battery 3 is connected in parallel with the hydrogen fuel cell 8.

[0028] like Figure 1As shown, a cover plate 4 is installed on the upper end of the loading cylinder 1 by screws, and the cover plate 4 has a clearance hole that is arranged through the side facing the hydrogen storage area 12, and the clearance hole is arranged opposite to the hydrogen storage bottle 2; the cover plate 4 is installed with a handle 5 for easy carrying on the side facing the fuel cell area 11. In the specific implementation, the height of the pressure reducing valve and the bottle body can be smaller than the loading cylinder, and only a clearance hole for the hydrogen delivery pipeline needs to be left on the loading cylinder. In order to reduce the pressure during output or hydrogenation, a three-way pressure reducing valve 21 is provided on the hydrogen storage bottle 2, and the pressure reducing valve 21 just passes through the clearance hole, and the hydrogen outlet end of the pressure reducing valve is connected to the air inlet end of the hydrogen fuel cell through a hydrogen delivery pipe. In addition, a current output interface 6 and a CAN interface 7 are also provided on the cover plate 4.

[0029] In order to prevent dust and other impurities from blocking the air flow path of the fuel cell, a layer of dustproof net is also provided on the air inlet 111.
