Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen-powered two-wheel vehicles, and particularly to a hydrogen-powered bicycle. Background Art

[0002] A hydrogen-powered bicycle refers to an electromechanical integrated personal transportation vehicle that uses hydrogen energy as an auxiliary energy source based on an ordinary bicycle. Its main components include a frame and a hydrogen storage device, a fuel cell stack, and a controller installed on the frame. Due to the limited space of the hydrogen-powered bicycle, considering the weight balance of the fuel cell stack, in the prior art, the fuel cell stack is usually placed at the bottom of the vehicle body (for example, the applicant's prior application, publication number CN216783752U) or in the middle position of the vehicle body (for example, the applicant's prior application, publication number CN116278825A). Therefore, a specific structure for installing the fuel cell stack needs to be added at the bottom or the center position of the original frame, and the addition of the new structure will lead to the complication of the overall frame structure, resulting in an increase in production costs and the difficulty of installation and maintenance.

[0003] In addition, since the low-pressure hydrogen storage device contains hydrogen storage alloy powder, there will be a problem that when placed flat or upside down, the metal powder will directly block the hydrogen outlet of the hydrogen storage device, resulting in the inability to output hydrogen. Therefore, in the prior art solutions, the hydrogen storage device is generally placed at the inclined pipe position and its hydrogen outlet is facing upward to avoid blockage by metal powder. However, whether the fuel cell stack is placed at the bottom of the vehicle body or in the middle position of the vehicle body, the fuel cell stack is installed in the opposite direction of the hydrogen outlet of the hydrogen storage device. Therefore, there is a problem that the hydrogen pipe between the fuel cell stack and the hydrogen storage device needs to pass through the inclined pipe and the lower half of the frame, resulting in a long pipeline, easy bending, and an increased risk of hydrogen leakage; and the installation position of the fuel cell stack is lower than the hydrogen outlet of the hydrogen storage device, and hydrogen has a small specific gravity and is easy to escape upward. Therefore, this layout scheme is also not conducive to the transmission of hydrogen. Summary of the Invention

[0004] The purpose of the present invention is to overcome the defects of the prior art, and provides a hydrogen-powered bicycle, which can achieve the purpose of simplifying the overall frame structure, reducing production costs and the difficulty of installation and maintenance, and optimizing the layout of the hydrogen pipeline.

[0005] To achieve the above and other purposes, the present invention is realized by including the following technical solutions: The present invention provides a hydrogen-powered bicycle, including a frame body, including a front pipe, an inclined pipe, and a basket. One end of the inclined pipe is fixedly arranged behind the front pipe, and the basket is installed in front of the front pipe; a fuel cell box, detachably installed below the basket; a hydrogen storage device, installed in the inclined pipe, and its hydrogen outlet faces the front pipe, and the hydrogen outlet is connected to the fuel cell box through a hydrogen pipeline.

[0009] In one embodiment, an air outlet is formed in the middle of the rear end face of the cartridge body, and a fan on the fuel cell is located at the air outlet; an air inlet is formed in the middle of the front end face of the cartridge body.

[0010] In one embodiment, a lamp hole is further formed in the front end face of the cartridge body, and the lamp hole is disposed directly below the air inlet for exposing a front vehicle lamp built in the cartridge body.

[0011] In one embodiment, the basket includes a basket frame, a curved tube, a hook, and a binding net.

The hydrogen storage device can adopt a low-pressure metal hydride hydrogen storage device to ensure safe hydrogen delivery under a constant pressure; at the same time, it is possible to avoid adding a specific structure for fuel cell installation at the bottom or the center position of the frame, thereby simplifying the overall structure of the frame, reducing the production cost and the difficulty of installation and maintenance; in addition, under the detachable design, the fuel cell cartridge can not only charge the whole vehicle, but also be removed and used as a mobile power source or an emergency power source.

[0017] 2. The fuel cell of the present invention is horizontally installed in the box body. Compared with the vertical installation of the fuel cell in the prior art, the design height of the box body can be significantly reduced.

[0018] 3. Since hydrogen has a small specific gravity and is easy to escape upward, the installation height of the fuel cell of the present invention is higher than the setting height of the hydrogen outlet, which is beneficial to the transmission of hydrogen.

[0019] 4. The fuel cell of the present invention is arranged in the middle position of the battery box, which can facilitate the installation of control devices such as controllers and rechargeable batteries on one side or both sides thereof, and is convenient for energy management of the hydrogen energy vehicle.

[0036] Please refer to Figures 1 - 5 . The following specific examples illustrate the implementation manners of the present invention, and those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0037] It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those skilled in the art to understand and read, and are not used to limit the limited conditions under which the present invention can be implemented. Therefore, they do not have technical essence.

[0038] In the present invention, the serial numbers assigned to the components themselves, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. And the "connection" mentioned in the present invention, unless otherwise specified, includes both direct and indirect connections. The term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, including not only those elements listed, but also other elements not specifically listed.

[0039] Such as Figure 1As shown in the figure, the present invention provides a hydrogen energy bicycle, which includes a frame main body 100, a fuel cell box 200 and a hydrogen storage device 300. The frame main body 100 includes a front tube 110, an inclined tube 120 and a basket 130. The front tube 110 is used for installing a handlebar vertical rod 140; one end of the inclined tube 120 is fixedly arranged behind the front tube 110, and the other end of the inclined tube 120 is inclined backward and downward compared with its one end; the basket 130 is installed in front of the front tube 110; the fuel cell box 200 is detachably installed under the basket 130. When the fuel cell box 200 is installed under the basket 130, it serves as the power source of the hydrogen energy bicycle; when the fuel cell box 200 is detached from under the basket 130, it can be directly used as a mobile power source or an emergency power source. The hydrogen storage device 300 is installed in the inclined tube 110, and the hydrogen outlet 310 of the hydrogen storage device 300 faces the front tube 120 and is connected to the fuel cell box 200 through a hydrogen pipeline.

[0040] As Figure 2 and Figure 3 shown in the figure, the fuel cell box 200 includes a box body 210, a fuel cell 220 and a front headlight. An air outlet 211 is opened on the end face (i.e., the rear end face) of the box body 210 facing the front tube 110. An air inlet 212 and a lamp hole 213 are opened on the end face (i.e., the front end face) of the box body 210 facing away from the front tube 110. The air inlet 212 is used for sucking in air to obtain oxygen; the lamp hole 213 can be arranged directly below the air inlet 212 for exposing the front headlight built in the box body 210. The fuel cell 220 can supply power to the front headlight so that it can be used for lighting; further, the lamp hole 213 can be arranged at the middle position of the front end face of the box body 210 to increase its lighting range.

[0041] As Figure 4 shown in the figure, the fuel cell 220 is horizontally installed in the box body 210. Different from the vertical installation of the fuel cell in the prior art, the horizontal installation can significantly reduce the design height of the box body. A fan 221 is arranged on the fuel cell 220, and the fan 221 is located on the side close to the air outlet 212. Specifically, the fuel cell 220 can be arranged at the middle position of the box body 210, and controllers 230 are respectively installed on both sides of the fuel cell 220, and the fuel cell 220 and the controllers 230 are respectively connected by lines. Further, rechargeable batteries 240 can also be installed on both sides of the fuel cell 220 to store the electric energy generated by the fuel cell 220.

[0042] Since the fuel cell 220 is disposed below the basket 130, the hydrogen energy bicycle will shake and sway during driving. Therefore, the gas and wire routing structure of the present invention needs to protect the circuit, especially the gas path.

[0043] As Figure 5 shown, the hydrogen storage device 300 can adopt a low-pressure metal hydride hydrogen storage device. The hydrogen in the hydrogen storage device enters the trachea after being decompressed by the valve body 320 to ensure the safe transmission of hydrogen under a constant pressure. The hydrogen storage device 300 is installed in the inclined tube 120. The hydrogen outlet 310 of the hydrogen storage device 300 is connected to the fuel cell 220 through a hydrogen pipeline, so that the hydrogen storage device 300 can supply hydrogen to the fuel cell 220. Compared with the prior art, the fuel cell 220 is located directly in front of the hydrogen outlet 310, which can significantly shorten the layout length of the hydrogen pipeline and effectively avoid the problems of easy bending and hydrogen leakage caused by too long hydrogen pipeline.

[0044] Furthermore, since hydrogen has a small specific gravity and is easy to escape upward, the installation height of the fuel cell 220 can be higher than the installation height of the hydrogen outlet 310, which is conducive to the transmission of hydrogen.

[0045] As Figure 6 shown, since the fuel cell box 200 is installed below the basket 130, it will increase the overall occupied space of the basket 130 and the fuel cell box 200. Therefore, to solve this problem, different from the traditional basket with a large storage space, the storage space of the basket 130 of the present invention needs to be reduced. However, the reduction of the storage space will affect the storage stability of large items in the basket 130. Therefore, the design of the basket 130 can include a basket frame 131, a bent tube 132, a hook 133 and a binding net. The lower end of the basket frame 131 is fixedly connected with a plurality of the bent tubes 132 to form a recessed portion 134. A plurality of hooks 133 are distributed on the basket frame. The binding net is elastic, and both ends of the binding net can be respectively hung on the hooks of the basket frame 131, so that items can be stably fixed in the recessed portion 134 of the basket 130.

[0046] Specifically, the basket 130 can be integrally formed with the front tube 110, or can be connected to the front tube 110 by means of welding, bolt fixing, etc. to improve the installation strength of the basket 130. The basket 130 can not only be an independent functional part for holding items, but also can be used as a connecting structure to facilitate the installation of the fuel cell box 200. Specifically, refer to the appendix Figure 4, a chute / slide rail is provided on the lower surface of the bent pipe 132, and a slide rail / chute that fits with it is provided on the upper surface of the fuel cell box 200. The user can slide the fuel cell box 200 until it abuts against the front pipe 110 to complete the installation of the fuel cell box 200. Similarly, the disassembly of the fuel cell box 200 can be achieved. Moreover, after the fuel cell box 200 is fixed, the fitting structure of the chute and the slide rail can further improve the stability of the basket 130 and the fuel cell box 200.

[0047] As Figure 7 shown, the frame body 100 further includes a rear lower fork 150 and a chain guard 160. The rear lower fork 150 and the chain guard 160 are of an integral structure and are connected to the inclined pipe 120 through the rear standpipe, which has better strength. At the same time, the step of installing the chain guard 160 can be omitted, making the installation simpler and faster, and reducing the operation and maintenance costs of the product for the manufacturer in the future. Further, the chain guard 160 is in an annular structure and is used to completely cover the chain 170 and the sprocket 180, which can make the overall vehicle model more concise and beautiful.

[0048] Further, a fender fixing member 161 is provided at the rear ends of the chain guard 160 and the rear lower fork 150 respectively. The fender fixing member 161 is a support rod; the fender 190 is fixed at two points through the two fender fixing members 161, the front end fixing member of the chain guard 160 and the rear lower fork 150. By providing the fender fixing member 161 on the chain guard 160 and the rear lower fork 150, the structural strength of the frame body 100 and the fender 190 can be effectively improved. By fixing the fender 190 at two places, the fender can be conveniently and quickly installed in the middle position of the bicycle, effectively improving the production efficiency, saving labor, and saving labor costs.

[0049] Therefore, the present invention effectively overcomes various disadvantages in the prior art and has high industrial utilization value. The above embodiments are only illustrative of the principles and effects of the present invention and are not used to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
