Description

Technical Field

[0001] The present invention belongs to the field of hydrogen energy applications, and in particular, to a hydrogen power assembly system and a hydrogen energy bicycle. Background Art

[0002] A hydrogen energy bicycle refers to an electromechanical integrated personal transportation vehicle that uses hydrogen energy as an auxiliary energy source based on a bicycle; its main components include a hydrogen fuel cell, a hydrogen storage device, a controller, a motor, lamps, a frame, etc. Due to the limited space position of the hydrogen energy vehicle, the installation space is very limited. How to make full use of the vehicle body space and be structurally compact is a problem that those skilled in the art need to fully consider.

[0003] There are also several hydrogen energy bicycles in the related art. For example, in the prior applications of the company (publication numbers: CN216783752U, CN116278825A), in the hydrogen power system of the hydrogen energy vehicle, the hydrogen fuel cell is arranged at the rear of the vehicle body, and there is a solid hydrogen storage material in the hydrogen storage device. Generally, the hydrogen outlet of the hydrogen storage device faces upward, resulting in the opposite setting directions of the hydrogen inlet of the hydrogen fuel cell and the hydrogen outlet of the hydrogen storage device. As a result, the hydrogen supply pipeline needs to pass through the entire inclined pipe and the frame, so the pipeline of the hydrogen supply pipeline is longer and the bending degree is higher, which will lead to poorer stability of the hydrogen supply pipeline and a higher risk of hydrogen leakage. Summary of the Invention

[0004] In order to overcome the above technical defects, the present invention provides a hydrogen power assembly system and a hydrogen energy bicycle to solve the problems involved in the background art.

[0011] Preferably or optionally, a basket is further arranged on the front end face of the sleeve;

[0012] The basket includes a basket frame, and a plurality of curved reinforcing ribs are fixedly connected to the lower end of the basket frame to form a concave area with a hollow structure;

[0019] An air inlet is provided in the middle of the front end surface of the battery box, an air outlet is provided in the middle of the rear end surface of the battery box, and the fan on the fuel cell corresponds to the air outlet.

[0020] Preferably or optionally, the second chamber also has a built-in controller and a rechargeable battery electrically connected to the fuel cell.

[0021] Preferably or optionally, the hydrogen source comprises: a hydrogen storage device that uses solid hydrogen storage materials to store hydrogen, and a pressure reducing valve connected to the hydrogen storage device.

[0022] The present invention also provides a hydrogen-powered bicycle, comprising the hydrogen power assembly system.

[0023] The present invention relates to a hydrogen power assembly system and a hydrogen bicycle, which have the following beneficial effects compared with the prior art:

[0024] 1. The present invention arranges the fuel cell in front of the hydrogen outlet of the hydrogen source, thereby shortening the layout length of the hydrogen supply pipeline, avoiding excessive bending of the hydrogen supply pipeline, effectively avoiding stability problems such as easy bending of the pipeline caused by the overlong hydrogen supply pipeline, and reducing the risk of hydrogen leakage. Moreover, 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 of the hydrogen source, which is more conducive to the transmission of hydrogen.

[0025] 2. The present invention installs the battery box in a detachable manner. The battery box and the built-in fuel cell, as a whole, can not only charge the whole vehicle, but also be removed and used as a mobile power source or emergency power source in combination with the detachable hydrogen source.

[0026] 3. The basket of the present invention forms a sunken area with a hollow structure for placing items; at the same time, it cooperates with hooks to fix the restraint belt or restraint net, ensuring that the items can be stably fixed in the basket while reducing the storage space.

[0027] 4. The present invention fixes the battery box and the basket together through the cooperation of the chute and the slide rail, improving the stability of the basket and the battery box, and at the same time facilitating the disassembly and assembly of the battery box.

[0028] 5. The present invention designs the shape of the basket and / or the battery box. On the one hand, designing the battery box as an inverted trapezoidal structure has relatively good structural strength; on the other hand, the upper surface of the battery box can be used as the bottom surface of the basket, facilitating the basket to hold items, and the basket and the reinforcing ribs can be used as the anti-collision structure of the battery box to protect the battery box.

[0029] 6. The present invention further improves the structural stability of the battery box by installing a lifting frame on the front end face of the sleeve to lift the battery box.

[0030] 7. The present invention designs the hydrogen supply pipeline into three sections and seals and connects them through a quick-connect device, facilitating the disassembly and assembly between the hydrogen source and the fuel cell; at the same time, the second gas path is arranged along the inner wall of the sleeve, which can avoid contact and friction with the front vertical rod of the vehicle head, ensuring the stability of the hydrogen supply pipeline.

[0031] 8. The present invention horizontally installs the fuel cell in the battery box. Compared with the vertical installation of the fuel cell in the prior art, it can significantly reduce the design height of the battery box. In addition, the present invention sets the air inlet on the front end face, and uses the airflow formed by the vehicle driving to assist the heat dissipation of the fuel cell, improving the heat dissipation effect of the entire hydrogen power assembly system.

[0032] 9. The present invention arranges the fuel cell in the middle position of the battery box, which is convenient to install control devices such as controllers and rechargeable batteries on both sides, facilitating the energy management of the hydrogen-powered vehicle.

[0033] 10. The hydrogen storage device and the pressure reducing valve of the present invention are set as an integrated structure, which is convenient for the overall disassembly and maintenance of the hydrogen source. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0041] In the following description, numerous specific details are given to provide a more thorough understanding of the present invention. However, it will be apparent to one of ordinary skill in the art that the present invention may be practiced without one or more of these details. In other instances, well-known technical features have not been described in order to avoid obscuring the present invention.

[0042] Refer to the attached Figures 1 to 6A hydrogen powertrain system is applied to a hydrogen bicycle. The main components of the hydrogen bicycle include a frame, a driving device, the hydrogen powertrain system, a central control device and a power storage device. The hydrogen powertrain system supplies power to the driving device, so that the pedals and / or the driving device drive the hydrogen bicycle forward. The hydrogen powertrain system includes: an inclined tube 100, a hydrogen source 200, a battery box 300 and a fuel cell 400.

[0043] The inclined tube 100 is a part of the frame, and is used to connect the seat and the handlebar. Specifically, the inclined tube 100 includes a main body 110 of a tubular structure, a first cavity 120 formed inside the main body 110, and a sleeve 130 arranged at the upper end of the inclined tube 100; a front vertical rod 700 is rotatably installed in the sleeve 130. The hydrogen source 200 includes a hydrogen storage device 210 that uses solid hydrogen storage materials to store hydrogen, and a pressure reducing valve 220 connected to the hydrogen storage device 210. The hydrogen storage device 210 and the pressure reducing valve 220 can be an integrated design to facilitate the overall disassembly and maintenance of the hydrogen source 200, wherein the hydrogen storage device 210 and the pressure reducing valve 220 are both placed in the first cavity 120, and the hydrogen outlet of the hydrogen source 200 is close to the upper end of the inclined tube 100. The battery box 300 is installed on the front end surface of the sleeve 130 , and a second cavity is formed inside the battery box 300 ; the fuel cell 400 is placed in the second cavity and connected to the hydrogen source 200 via a hydrogen supply pipeline 500 .

[0044] Since the fuel cell 400 is located on one side of the hydrogen outlet of the hydrogen source 200, the arrangement length of the hydrogen supply pipeline 500 can be shortened, and the hydrogen supply pipeline 500 is prevented from being excessively bent, and stability problems such as easy bending of the hydrogen supply pipeline 500 caused by the hydrogen supply pipeline 500 being too long can be effectively avoided, thereby reducing the risk of hydrogen leakage. Moreover, since hydrogen has a small specific gravity and is easy to escape upward, the installation height of the fuel cell 400 of the present invention is higher than the setting height of the hydrogen outlet of the hydrogen source 200, which is more conducive to the transmission of hydrogen.

[0045] In a further embodiment, the rear end face of the battery box 300 is fixedly mounted on the front end face of the sleeve 130 in a detachable manner. In this way, the battery box 300 and the built-in fuel cell 400 as a whole can charge the entire vehicle, and can also be removed and used as a mobile power source or emergency power source. When used as a mobile power source or emergency power source, the battery box should have a power output interface. This embodiment provides an exemplary detachable method, see the attached Figure 5, a first mounting tube 140 is provided on the front end face of the sleeve 130, and a second mounting tube 320 is provided on the rear end face of the battery box 300; and the shape and size of the connecting end faces of the first mounting tube 140 and the second mounting tube 320 are the same, and annular protruding portions are provided on both, and the battery box 300 is fixed by fitting and fixing the annular protruding portions on both sides with a clamp 330.

[0046] In a further embodiment, refer to the appendix Figure 3 , a basket 600 is further provided on the front end face of the sleeve 130. The basket 600 can be an integrally formed structure with the sleeve 130, or can be connected to the sleeve 130 by means of welding, bolt fixing, etc. to improve the installation strength of the basket 600. The basket 600 is fixedly connected to the sleeve 130 by bolts. Since the battery box 300 is installed below the basket 600, the overall occupied space of the basket 600 and the battery box 300 will be increased. Therefore, to solve this problem, different from the traditional basket 600 with a large storage space, the storage space of the basket 600 in this embodiment needs to be reduced. However, the reduction of the storage space will affect the storage stability of large items in the basket 600. Therefore, in this embodiment, the structure of the basket 600 is further designed. The basket 600 includes a basket frame 610, and a plurality of curved reinforcing ribs 620 are fixedly connected to the lower end of the basket frame 610 to form a recessed area with a hollow structure; a plurality of hooks 630 are also distributed on the side surface of the basket frame 610, which are suitable for fixing a restraint band or a restraint net. The hooks 630 cooperate with the restraint band or the restraint net to ensure that the items can be stably fixed in the basket 600 while reducing the storage space.

[0047] It should be noted that the basket 600 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 battery box 300. Specifically, refer to the appendix Figure 4 , a chute / rail 640 is provided on the lower surface of the reinforcing rib 620, and a rail / chute 310 is provided on the upper surface of the battery box 300 and is fitted with it. The user can slide the battery box 300 until the first mounting tube 140 abuts against the second mounting tube 320 to realize the installation of the battery box 300. Similarly, the disassembly of the battery box 300 can be realized. Moreover, when the first mounting tube 140 and the second mounting tube 320 are fixed, the fitting structure of the chute and the rail can further improve the stability of the basket 600 and the battery box 300.

[0048] In addition, the cross-sectional area of the basket 600 and / or the battery box 300 gradually decreases along the vertical direction downward. The upper surface of the battery box 300 is substantially the same in shape and size as the lower surface of the recessed area of the basket 600, and the gap between the upper surface of the battery box 300 and the lower surface of the recessed area is small, even zero, that is, the upper surface of the battery box 300 is in contact with the lower surface of the recessed area. This means that the upper surface of the battery box 300 can serve as the bottom surface of the basket 600, facilitating the basket 600 to hold small-sized items. At the same time, both the basket 600 and the battery box 300 are inverted trapezoidal structures, having relatively good structural strength. Moreover, the outer edge of the basket 600 protrudes beyond the outer edge of the battery box 300 to form an anti-collision structure. When the vehicle undergoes a minor collision or rollover, the basket 600 and the reinforcing rib 620 can play a role in protecting the battery box 300 and the built-in fuel cell 400.

[0049] In addition, to avoid the problem of "top-heavy and bottom-light" in the hydrogen energy bicycle, the sum of the load weights of the fuel cell 400 and the basket 600 does not exceed a preset value (generally 5 kg) to meet the design requirements. In this embodiment, a lightweight fuel cell 400 is selected, such that the sum of the weights of the fuel cell stack, the rechargeable battery, and the controller of the fuel cell 400 does not exceed 3 kg. Even if this fuel cell stack is placed at the front of the vehicle body, it will not cause the problem of "top-heavy and bottom-light".

[0050] In a further embodiment, a lifting frame is further installed on the front end face of the sleeve 130. By installing a lifting frame on the front end face of the sleeve 130, the battery box 300 is lifted, further improving the structural stability of the battery box 300. That is to say, in this embodiment, through the sliding groove and sliding rail fitting connection between the basket 600 and the battery box 300, the detachable connection between the battery box 300 and the sleeve 130, and the lifting effect of the lifting frame, triple fixation of the battery box 300 and the fuel cell 400 is achieved, improving the load-bearing capacity and structural stability of the battery box 300.

[0051] In a further embodiment, the hydrogen supply pipeline 500 includes: a first gas path 510 connected to the fuel cell 400, a second gas path 520 passing through the sleeve 130 and arranged along the inner wall of the sleeve 130, a third gas path 530 connected to the hydrogen source 200, a first quick-connect device 540 provided at the connecting end of the first gas path 510 and the second gas path 520, and a second quick-connect device 550 provided at the connecting end of the second gas path 520 and the third gas path 530. In this embodiment, the hydrogen supply pipeline 500 is designed into three sections and sealed and connected by quick-connect devices, so as to facilitate the disassembly and assembly between the hydrogen source 200 and the fuel cell 400; at the same time, the second gas path 520 is arranged along the inner wall of the sleeve 130, so as not to contact and rub against the front vertical rod 700 of the vehicle, thereby ensuring the stability of the hydrogen supply pipeline 500.

[0052] Among them, the first quick-connect device 540 and the second quick-connect device 550 are quick-connect devices of the same signal, and the first quick-connect device 540 on the connection end of the first gas path 510 and the second quick-connect device 550 on the connection end of the third gas path 530 can be adapted to each other, and the hydrogen source 200 and the fuel cell 400 can be removed and connected to be used as a mobile power supply or emergency power supply.

[0053] In further embodiments, see the attached Figure 6 The fuel cell 400 is installed horizontally in the battery box 300. Different from the vertical installation of the fuel cell 400 in the prior art, the horizontal installation can significantly reduce the design height of the battery box 300. An air inlet 340 is provided in the middle of the front end surface of the battery box 300, and an air outlet 350 is provided in the middle of the rear end surface of the battery box 300. The fan 410 on the fuel cell 400 corresponds to the air outlet 350. In this embodiment, the air inlet 340 is arranged on the front end surface, and the airflow formed by the vehicle driving assists the heat dissipation of the fuel cell 400, thereby improving the heat dissipation effect of the entire hydrogen powertrain system. Moreover, a louver structure is provided at the air inlet 340 to play the role of ventilation, diversion and rain protection.

[0054] In addition, the second cavity is also built with a shell 800, and the shell 800 is used to place the controller and rechargeable battery electrically connected to the fuel cell 400. The rechargeable battery is a power storage device, and the rechargeable battery is used to store the electrical energy generated by the fuel cell 400. The rechargeable battery and the fuel cell 400 can be used to power the drive device alone or together to drive the entire vehicle. Various sensors are also provided on the fuel cell 400 and the hydrogen source 200, which can detect the relevant parameters of the fuel cell 400 and the hydrogen source 200 in real time, and the working conditions of the fuel cell 400 and the rechargeable battery are controlled by the controller to achieve energy management of the entire vehicle.

[0055] In addition, it should be noted that, in the above specific embodiments, the various specific technical features described can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present invention will not separately describe various possible combination manners.
