TECHNICAL FIELD

[0001] The present application relates to the field of hydrogen fuel electric vehicles, in particular to an integrated power supply device for hydrogen fuel electric moped. BACKGROUND

[0002] Hydrogen fuel cells are power generation devices that directly convert the chemical energy of hydrogen and oxygen into electrical energy. Hydrogen fuel cells can be used in mobile devices, automobiles and other fields, and have the characteristics of high efficiency, energy saving, environmental protection, etc. The existing hydrogen fuel electric moped generally uses hydrogen fuel cells for power supply, and needs to add hydrogen. In actual use, a detachable hydrogen cylinder is usually used for replacement. Therefore, it is necessary to facilitate installation and disassembly, and also to ensure the stability of the hydrogen cylinder after installation. The existing hydrogen cylinder is generally fixed after installation. When the hydrogen cylinder needs to be disassembled, the fixing needs to be released first, and then the hydrogen cylinder needs to be removed, which is not convenient to use.

[0003] Therefore, an integrated power supply device for hydrogen fuel electric moped is needed to solve the above problems. CONTENT OF THE UTILITY MODEL

[0004] The content part of the present application is used to introduce the concept in a simple form, which will be described in detail in the specific embodiment part.

[0006] The positioning groove and the positioning protrusion can position the hydrogen cylinder placed in the placing groove, ensure that it is placed in the correct position, and the stabilizing block and the stabilizing pad can position the side wall of the hydrogen cylinder when the hydrogen cylinder is placed in the placing groove, avoiding shaking of the hydrogen cylinder.

[0007] Further, the groove block is fixedly arranged in the limiting frame, a boss with one end located in the placing groove is slidably connected in the limiting frame, the stable pad is fixed on the upper end surface of the boss, and the boss and the stable block are connected through the linkage assembly.

[0008] When the hydrogen cylinder is placed into the placing groove, the boss is pushed, and then the stable block supports the hydrogen cylinder through the linkage member, so that the stable block does not block the hydrogen cylinder when the hydrogen cylinder is placed, and the hydrogen cylinder is prevented from shaking in the placing groove after being placed.

[0009] Further, the boss and the limiting frame are connected with a reset spring, and a side groove accommodating the stable block is formed in the side wall of the placing groove.

[0010] When the hydrogen cylinder is taken out, the boss returns to the initial position under the action of the reset spring, so that the stable block no longer supports the hydrogen cylinder, and the hydrogen cylinder is convenient to take out.

[0011] Further, the groove block is fixedly connected with a supporting rib supported in the inner cavity of the placing seat.

[0012] The linkage member comprises: a curved rod hinged to the supporting rib, the bending position of the curved rod is hinged to the supporting rib, and the curved rod further comprises a first part and a second part, and the first part and the second part are connected through the bending part.

[0013] The supporting rib can ensure the overall strength of the groove block, prevent the groove block from being damaged due to the excessive weight of the hydrogen cylinder, and the curved rod can support the hydrogen cylinder through the stable block after the hydrogen cylinder is placed into the placing groove.

[0014] Further, the stable block is fixedly arranged at one end of the first part, the second part is inserted into the limiting frame, and the second part is fixedly connected with a sliding block slidably connected in the limiting frame.

[0041] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] Reference Figures 1-6An integrated power supply device for a hydrogen fuel cell electric bicycle includes: a placement seat 10, a hydrogen cylinder 11, an inner cavity 12, an upper end plate 13, a recessed block 14, a placement groove 15, a barrier 16, a positioning groove 17, a protrusion 18, a stabilizing block 19, and a stabilizing pad 20. The placement seat 10 has an inner cavity 12 for placing a battery. The placement seat 10 has an upper end plate 13 located above the inner cavity 12. A recessed block 14 is fixedly connected to the upper end face of the upper end plate 13. The recessed block 14 is recessed towards the inner cavity 12 of the placement seat 10, forming four placement grooves 15 with upper openings. The hydrogen cylinder 11 is placed within the placement grooves 15. A positioning groove 17 extending to the bottom of the hydrogen cylinder 11 is formed on the side wall of the hydrogen cylinder 11. A protrusion 18 for embedding into the positioning groove 17 is provided on the inner side wall of the placement groove 15. When the hydrogen cylinder 11 is placed into the placement slot 15, the protrusion 18 is inserted into the positioning slot 17 for guidance, ensuring that the placement angle of the hydrogen cylinder 11 remains consistent. To facilitate the removal of the hydrogen cylinder 11, there is a gap between the placement slot 15 and the hydrogen cylinder 11. Therefore, when the hydrogen cylinder 11 is placed into the placement slot 15, it will wobble. In one embodiment, multiple circumferentially distributed side slots 21 are formed on the side wall of the placement slot 15. A limiting frame 23 located at the bottom of the placement slot 15 is fixedly connected to the recessed block 14. A boss 22 is slidably connected inside the limiting frame 23. The upper end of the boss 22 is located inside the placement slot 15 and is fixedly connected to a stabilizing pad 20. When the hydrogen cylinder 11 is placed into the placement slot 15, it will press on the boss 22 and push the boss 22 downward. A return spring 24 is connected between the boss 22 and the limiting frame 23. When the boss 22 is not pressed on, the boss 22 returns to its original position.

[0043] A support rib 25 is fixedly connected to the recessed block 14 and supported in the inner cavity 12 of the placement seat 10. A horizontal plate 26 is fixedly connected in the inner cavity 12 of the placement seat 10, and the support rib 25 is supported on the horizontal plate 26. The horizontal plate 26 divides the inner cavity 12, and the battery is placed on the lower side of the horizontal plate 26. The recessed block 14 is supported by the support rib 25. A bending rod 27 is hinged to the support rib 25. The bending position of the bending rod 27 is hinged to the support rib 25. The bending rod 27 also includes a first part 28 and a second part 29, which are connected by the bending part. A stabilizing block 19 is fixedly set at one end of the first part 28, and the second part 29 is inserted into the limiting frame 23 and fixedly connected to a sliding block 30 that slides in the limiting frame. When the boss 22 is pressed, the stabilizing block 19 will move towards the hydrogen cylinder 11 under the action of the bending rod 27, and support the hydrogen cylinder 11 to prevent the hydrogen cylinder 11 from shaking. The sliding block 30 abuts against the upper side of the inner wall of the limiting frame 23 and slides in cooperation with the upper inner wall of the limiting frame 23.

[0044] In one embodiment, a baffle 16 is provided at the upper end of the placement base 10. The baffle 16 extends along the edge of the upper surface of the placement base 10 and has a rear side portion 31 extending along the rear edge of the upper surface of the placement base 10 and two side portions 32 extending along the left and right sides of the upper surface of the placement base 10. A first heat dissipation groove 33 communicating with the inner cavity 12 of the placement base 10 is formed on the front end surface of the placement base 10, a second heat dissipation groove 34 communicating with the inner cavity 12 of the placement base 10 is formed on the rear end surface of the placement base 10, and a third heat dissipation groove 35 is formed on both the left and right side surfaces of the placement base 10.

[0045] Working process or usage method:

[0046] 1. When the hydrogen cylinder 11 is placed into the placement slot 15, it will press down on the boss 22, causing the boss 22 to move downwards. Under the action of the bending rod 27, the stabilizing block 19 is supported on the side of the hydrogen cylinder 11, preventing the hydrogen cylinder 11 from shaking.

[0047] 2. When it is necessary to remove the hydrogen cylinder 11 for replacement, after lifting the hydrogen cylinder 11, the boss 22 will return to the initial position under the action of the return spring 24. At this time, the stabilizing block 19 will no longer support the hydrogen cylinder 11, making it easier to remove the hydrogen cylinder 11.
