[0037] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation mode of the present invention is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are elaborated to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] This application provides a hydrogen supply device for hydrogen fuel cell vehicles that is easy to disassemble and assemble. Please refer to Figure 1-Figure 14 : It includes a vehicle body 1, a hydrogen storage bin 2 and a hydrogen storage bottle 3, wherein the hydrogen storage bin 2 is located at the lower end of the vehicle body 1, two hydrogen storage bins 2 are provided and placed in parallel, and the openings of the hydrogen storage bins 2 face downward;

[0039] A lifting and translation mechanism is provided in the hydrogen storage bin 2. The height of the lifting and translation mechanism is less than the minimum ground clearance of the vehicle body 1. The lifting and translation mechanism includes a fixed part 4 and a moving part 5. The fixed part 4 drives the hydrogen storage bottle 3 to move in the vertical direction, and the moving part 5 drives the hydrogen storage bottle 3 to move in the horizontal direction. The moving part 5 drives the hydrogen storage bottle 3 to move a distance of 1.5-2 times the length of the hydrogen storage bottle 3 itself:

[0040] The telescopic end of the lifting and translation mechanism is equipped with a gas cylinder flipping mechanism, which includes a driving part 6 and a quick-release part 7. The driving part 6 drives the hydrogen storage bottle 3 to rotate from a horizontal position to a vertical position: the hydrogen fuel cell is connected to the driving part 6 through the quick-release part 7.

[0041] Specifically in practical applications, when the hydrogen storage bottle 2 needs to be disassembled, the fixed part 4 is controlled to work, and the fixed part 4 drives the moving part 5 to move downward out of the hydrogen storage bin 2, and then the moving part 5 is controlled to work, and the moving part 5 drives the hydrogen storage bottle 3 to move horizontally. Since the hydrogen storage bin 2 is long and needs to be turned over later, a long horizontal displacement is required. The moving part 5 is similar to the two-stage telescopic mechanism on the market, which is characterized by a telescopic range that is much larger than its own size. It is used in this application to enable the hydrogen storage bottle 3 to move to one side of the vehicle body 1;

[0042] Then, the driving unit 6 is controlled to work, driving the hydrogen storage bottle 3 to move from a horizontal position to a vertical position. By manually pressing the hydrogen storage bottle 3 downward and rotating it at a certain angle, the hydrogen storage bottle 3 can be removed to achieve the purpose of quick disassembly. According to actual application, when the distance moved by the hydrogen storage bottle 3 is greater than 1.5-2 times the length of the hydrogen storage bottle 3 itself, it can be moved to one side of the vehicle.

[0043] The purpose of providing two hydrogen storage bins 2 in parallel in the present application is to reduce the length of the hydrogen storage bottle 3 itself and facilitate automatic movement to the side of the vehicle body 1.

[0044] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The fixed part 4 includes a linear motor 8 installed at the upper end of the hydrogen storage tank 2. The linear motor 8 is provided with two pairs. The telescopic end of the linear motor 8 is installed with a side plate 9, and the upper end of the side plate 9 is fixedly connected to the linear motor 8.

[0045] Specifically in practical applications, the linear motor 8 is controlled to be fixedly connected to the automobile body 1 , and when the linear motor 8 is extended, it drives the side plate 9 to move downward, and the movement of the side plate 9 drives the hydrogen storage bottle 3 to move out of the automobile body 1 .

[0046] Reference Figure 1-Figure 9The moving part 5 includes a movable plate 10 arranged on one side of the side plate 9, a rotating motor 11 is installed at one end of the movable plate 10, a threaded shaft 12 is installed at the rotating end of the rotating motor 11, a slide groove 13 is opened on the surface of the threaded shaft 12, a threaded hole 14 engaged with the threaded shaft 12 is opened at one end of the movable plate 10, a limiting protrusion 15 is provided on one side of the threaded hole 14, a driving wheel 16 is installed on the threaded shaft 12, the limiting protrusion 15 is arranged on both sides of the driving wheel 16, the inner ring of the driving wheel 16 is slidably connected with the slide groove 13, a bearing 17 is installed at one end of the movable plate 10, and a threaded shaft 18 is installed on the inner ring of the bearing 17 ; An actuator plate 19 is provided on one side of the movable plate 10, and a threaded hole 20 meshing with the threaded shaft 18 is opened at one end of the actuator plate 19, and a driven wheel 21 meshing with the driving wheel 16 is installed at one end of the threaded shaft 18: the longitudinal section and cross-sectional shape of the side plate 9, the movable plate 10, and the actuator plate 19 are all L-shaped; sliding components are respectively installed between the side plate 9 and the movable plate 10, and between the movable plate 10 and the actuator plate 19, and the sliding components include a trapezoidal slide rail 22 and a trapezoidal protrusion 23, the trapezoidal slide rail 22 is fixedly installed on the actuator plate 19 and the movable plate 10, and the trapezoidal protrusion 23 is fixedly installed on the side plate 9 and the movable plate 10.

[0047] Specifically in practical applications, after the linear motor 8 is extended, the rotary motor 11 is controlled to rotate, and the rotation of the rotary motor 11 drives the threaded shaft 12 to rotate. The threaded shaft 12 is directly engaged with the threaded hole 14, so it can directly drive the movable plate 10 to move; the movable plate 10 also drives the limit protrusion 15 to move while moving. By setting the limit protrusion 15 on both sides of the driving wheel 16, the limit protrusion 15 pushes the driving wheel 16 to reciprocate along the extension direction of the threaded shaft 12. Through the sliding connection between the threaded shaft 12 and the slide groove 13, the threaded shaft 12 drives the driving wheel 16 to rotate, and can move along the threaded shaft 12, so that the driving wheel 16 and the driven wheel 21 always keep engaged;

[0048] The driving wheel 16 rotates to drive the driven wheel 21 to rotate the threaded shaft 18, and the threaded shaft 18 engages with the threaded hole 20 to drive the actuator plate 19 to move synchronously. Due to space limitations, the transmission ratio between the driving wheel 16 and the driven wheel 21 is relatively small. By controlling the transmission ratio between the threaded shaft 18 and the threaded hole 20, the movement speed of the actuator plate 19 and the movable plate 10 can be the same.

[0049] The movable plate 10 and the executive plate 19 can slide stably through the action of the sliding assembly. The longitudinal and cross-sectional shapes of the side plate 9, the movable plate 10 and the executive plate 19 are set to be L-shaped, which can meet the needs of the transmission structure while improving its own structural strength.

[0050] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 , Fig.11 and Fig.14 The driving part 6 includes a hollow beam 24 installed on the actuator plate 19, the lower end of the hollow beam 24 is hinged to the actuator plate 19, the actuator plate 19 is arranged at both ends of the hollow beam 24, and a triangular plate 25 is installed on the side surface of the hollow beam 24.

A threaded hole three 28 is provided at the center of the pin shaft 27; a rotating motor two 29 is installed at the lower end of the actuator plate 19, and the rotating motor two 29 is hinged to the actuator plate 19, and a threaded shaft three 30 meshing with the threaded hole three 28 is installed at the rotating end of the rotating motor two 29; a protective plate 31 is installed at the lower end of the hollow beam 24, and the protective plate 31 can block the opening of the hydrogen storage tank 2.

[0051] Specifically in practical applications, when the hydrogen storage bottle 3 is horizontally moved out of the vehicle body 1, the rotating motor 29 is controlled to rotate, and the lower end of the rotating motor 29 is hinged to the hollow beam 24 and is in a rotatable state. The rotating motor 29 drives the threaded shaft 30 to rotate, and the threaded shaft 30 drives the pin 27 to move upward. Since the lower sides of both ends of the hollow beam 24 are hinged to the execution plate 19, the hollow beam 24 can be rotated 90 degrees from a horizontal position to a vertical position through the force transmission of the triangular plate 25. Figures 4 to 14 The protective plate 31 can keep the hydrogen storage tank 2 in a relatively sealed state.

[0052] Reference Figure 2 , Figure 4 , Figure 5 , Fig.11 , Fig.12 and Fig.13 The quick-release portion 7 includes an L-shaped fixing rod 32 installed on the side surface of the hollow crossbeam 24. There are multiple L-shaped fixing rods 32 and they are arranged in a ring shape. A pin spring 33 is provided at the center of the L-shaped fixing rod 32.

An inclined surface 39 is provided between the strip groove 37 and the strip notch 36. A fixing cylinder 47 is installed on the side surface of the hollow crossbeam 24. The inner diameter of the fixing cylinder 47 is larger than the outer diameter of the hydrogen storage bottle 3.

[0053] Specifically in practical applications, when the hydrogen storage bottle 3 is in a vertical position, the L-shaped fixing rod 32 is stuck in the strip groove 37 through the action of the ejector spring 33, and the hydrogen storage bottle 3 can be pressed down manually, and the ejector spring 33 is compressed to the shortest position at this time. Fig.12 and Fig.13, rotate the hydrogen storage bottle 3 counterclockwise, the hydrogen storage bottle 3 drives the fixing ring 35 and the strip notch 36 to rotate to the position corresponding to the L-shaped fixing rod 32, and then lift the hydrogen storage bottle 3 upward, the hydrogen storage bottle 3 can be separated from the L-shaped fixing rod 32, so as to achieve the purpose of quick disassembly; the baffle 38 can avoid excessive rotation when installing the hydrogen storage bottle 3; the fixing cylinder 47 facilitates the installation of the hydrogen storage bottle 3.

[0055] Specifically in practical applications, the male self-detaching quick connector 40 and the female self-detaching quick connector 42 are in the prior art and are upgraded versions of hydraulic quick connectors. The male self-detaching quick connector 40 and the female self-detaching quick connector 42 can disconnect themselves when only subjected to pulling force, and can also be connected when only subjected to pushing force.

[0056] Reference Figure 1 , Figure 2 and Figure 3 A hydrogenation pipeline system 43 is provided on one side of the vehicle body, and the hydrogenation pipeline system 43 is connected to the transmission pipeline 41.

[0057] Specifically in practical applications, rapid hydrogenation operation can be achieved through the hydrogenation pipeline system 43.

[0058] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A ring handle 44 is installed near the bottle mouth of the hydrogen storage bottle 3. Manual rotation of the handle 44 realizes the quick release operation.

[0060] Specifically in practical applications, for the convenience of operation, the arc angle formed between the strip groove 37 and the strip notch 36 is 15-20 degrees.
