The connecting component 5 is used for connection and sealing between the vehicle hydrogen tank 6 and the pressure tank 7. A lifting assembly 3 is installed at the bottom of the ramp 1, and a parking seat 9 is installed at the top of the lifting assembly 3. The lifting assembly 3 lifts and lowers the parking seat 9 and the hydrogen tank 6. Storage box 2 is installed on the outside of ramp 1. Guide rails 10 are respectively provided on the inner wall of storage box 2 and the top of parking seat 9 for moving vehicle hydrogen tank 6. A conveying assembly 12 is provided between the two storage boxes 2 for moving vehicle hydrogen tank 6.

[0032] The limiting structure includes a return spring 401 and a limiting block 402. The limiting block 402 is slidably connected to the bottom of the vehicle body 4 and is used to reset the limiting block 402.

[0033] The connecting component 5 includes a first connecting pipe 501 and a second connecting pipe 505. The first connecting pipe 501 is connected to the pressure tank 7, and the second connecting pipe 505 is connected to the vehicle hydrogen tank 6. A first groove plate 502 is provided at one end of the first connecting pipe 501. A first spring 503 is installed inside the first groove plate 502. A long plate is slidably connected inside the first groove plate 502. A connecting plate 514 is connected to the outer wall of the long plate. The connecting plate 514 is used to close the port of the first connecting pipe 501. Slots 509 are provided on both sides of the first connecting pipe 501. A U-shaped frame 504 is fixedly connected to the outer wall of the first groove plate 502.

[0034] An L-shaped rod 507, a rubber slider 508, and an insert plate 510 are fixedly connected to the outer wall of the second connecting pipe 505. The insert plate 510 is inserted into the inside of the connecting plate 514. The rubber slider 508 is slidably connected to the inner wall of the slot 509 to play a sealing role. The L-shaped rod 507 lifts the long plate.

[0035] The bottom outer wall of the second connecting pipe 505 is connected to a second groove plate 506. A movable plate 512 is slidably connected to the inner wall of the second groove plate 506. A second spring 511 for resetting the movable plate 512 is installed inside the second groove plate 506. A bottom pressure block 513 is connected to one side of the movable plate 512. The U-shaped frame 504 pushes the bottom pressure block 513.

[0036] The lifting assembly 3 includes a bidirectional screw 301, a support frame 302, and a drive motor 305. The support frame 302 is fixedly connected to the outer wall of the storage box 2. The bidirectional screw 301 is rotatably connected to the support frame 302. The drive motor 305 is mounted on the inner wall of the storage box 2. The output shaft of the drive motor 305 is connected to the bidirectional screw 301. A connecting block 303 is threaded onto the outer wall of the bidirectional screw 301. A connecting arm 304 is rotatably connected to the top of the connecting block 303. The connecting arm 304 is connected to... The parking seat 9 is rotatably connected, and the connecting block 303 is slidably connected to the lower surface of the guide rail 10. The drive motor 305 of the lifting assembly 3 is started, and its output shaft drives the bidirectional screw 301 to rotate. Since the threads at both ends of the bidirectional screw 301 rotate in opposite directions, the two connecting blocks 303 connected by the threads on their outer walls slide towards each other along the lower surface of the guide rail 10. The connecting arm 304 rotatably connected to the top of the connecting block 303 rotates synchronously, pushing the parking plate 901 of the parking seat 9 to rise vertically to support the moving plate 11 and the hydrogen tank 6.

[0037] The parking seat 9 includes a parking plate 901, with a guide rail 10 fixedly connected to the upper surface of the parking plate 901, and a connecting arm 304 rotatably connected to the bottom of the parking plate 901.

[0038] A dual-axis motor 902 is mounted on the lower surface of the parking plate 901. A screw 903 is connected to the output shaft of the dual-axis motor 902. A sliding rod 904 is slidably connected to the bottom of the parking plate 901. The screw 903 passes through the sliding rod 904 and is threadedly connected. A push plate 905 is fixedly connected to one end of the sliding rod 904. The push plate 905 pushes the limiting block 402, activating the dual-axis motor 902 on the lower surface of the parking plate 901. Its output shaft drives the screw 903 to rotate. Because the screw 903 and the sliding rod 904 are threadedly engaged, and the sliding rod 904 is slidably connected to the bottom of the parking plate 901, when the screw 903 rotates, it pushes the sliding rod 904 to drive the push plate 905 to move laterally, pushing the limiting block 402 to move and release the limitation on the moving plate 11 and the hydrogen tank 6.

[0039] The conveying assembly 12 includes a servo motor 1201, synchronous pulleys 1202, and a synchronous belt 1203. The two synchronous pulleys 1202 are rotatably connected to the inner wall of the storage box 2, respectively. The servo motor 1201 is mounted on the outer wall of the storage box 2. The output shaft of the servo motor 1201 is connected to one of the synchronous pulleys 1202. The synchronous belt 1203 is driven between the two synchronous pulleys 1202. A fixing block is connected to the outer wall of the synchronous belt 1203. The servo motor of the conveying assembly 12 is activated. 1201 drives the synchronous pulley 1202 to rotate, and the synchronous pulley 1202 drives the synchronous belt 1203 to rotate. A fixed block is connected to the outer wall of the synchronous belt 1203. The fixed block pushes the extension plate 1101, thereby driving the moving plate 11 and the vehicle hydrogen tank 6 to move on the guide rail 10. For the transfer of the vehicle hydrogen tank 6, the fixed block makes a circular motion on the synchronous belt 1203. After the old vehicle hydrogen tank 6 is detached from the parking plate 901, the new vehicle hydrogen tank 6 is then pushed onto the parking plate 901.

[0040] A hydrogen storage tank 13 is installed at the bottom of the cover 102. A gas pipe 14 is connected to one side of the hydrogen storage tank 13. A control valve 8 is installed between the gas pipe 14 and the hydrogen storage tank 13. One end of the hydrogen storage tank 13 is connected to the interior of the storage box 2. One-way valves 601 are installed at both ends of the vehicle hydrogen tank 6. The one-way valves 601 are used to connect with one end of the gas pipe 14. When the vehicle hydrogen tank 6 is pushed to the end of the guide rail 10, the gas pipe 14 pushes the one-way valve 601 to open. The control valve 8 controls the hydrogen inside the hydrogen storage tank 13 to flow into the interior of the vehicle hydrogen tank 6 through the gas pipe 14. When the gas pipe 14 moves away from the one-way valve 601, the one-way valve 601 closes the port of the vehicle hydrogen tank 6 to allow the flow of hydrogen.

[0041] Working principle: The vehicle to be replaced drives into the wheel groove 101 on the upper surface of the ramp 1 to prevent the vehicle from deviating laterally. The cover 102 between the ramps 1 can block foreign objects to prevent them from falling into the area of ​​the hydrogen storage tank 13 below, while keeping the guide rail 10 clean.

[0042] After the vehicle wheels are positioned above the parking plate 901 of the parking seat 9, the drive motor 305 of the lifting assembly 3 is activated. Its output shaft drives the bidirectional screw 301 to rotate. Because the threads at both ends of the bidirectional screw 301 rotate in opposite directions, the two connecting blocks 303 connected by the threads on their outer walls slide towards each other along the lower surface of the guide rail 10. The connecting arm 304, which is rotatably connected to the top of the connecting block 303, rotates synchronously, pushing the parking plate 901 of the parking seat 9 to rise vertically, supporting the moving plate 11 and the vehicle hydrogen tank 6, thus activating the parking plate. The dual-axis motor 902 on the lower surface of 901 drives the screw 903 to rotate via its output shaft. Because the screw 903 is threadedly engaged with the sliding rod 904, and the sliding rod 904 is slidably connected to the bottom of the parking plate 901, the rotation of the screw 903 pushes the sliding rod 904, causing the push plate 905 to move laterally. This pushes the limiting block 402 to move and release the limiting on the moving plate 11 and the hydrogen tank 6. Subsequently, it descends, realizing the disassembly operation of the moving plate 11 and the hydrogen tank 6. The connecting assembly 5 automatically disengages. Figure 4 and Figure 5 As shown.

[0043] Combination Figure 9 As shown, the moving plate 11 and the vehicle hydrogen tank 6 continue to descend. Multiple guide rails 10 are connected to each other. The servo motor 1201 of the start conveyor assembly 12 drives the synchronous wheel 1202 to rotate. The synchronous wheel 1202 drives the synchronous belt 1203 to rotate. A fixed block is connected to the outer wall of the synchronous belt 1203. The fixed block pushes the extension plate 1101, thereby driving the moving plate 11 and the vehicle hydrogen tank 6 to move on the guide rail 10. For the transfer of the vehicle hydrogen tank 6, the fixed block makes a circular motion on the synchronous belt 1203. After the old vehicle hydrogen tank 6 is separated from the parking plate 901, the new vehicle hydrogen tank 6 is then pushed onto the parking plate 901. When the vehicle hydrogen tank 6 is pushed to the end of the guide rail 10, the gas pipe 14 pushes the one-way valve 601 to open, and the control valve 8 controls the hydrogen inside the hydrogen storage tank 13 to flow into the vehicle hydrogen tank 6 through the gas pipe 14. When the gas pipe 14 moves away from the one-way valve 601, the one-way valve 601 closes the port of the vehicle hydrogen tank 6. During the subsequent installation of the movable plate 11 and the vehicle hydrogen tank 6, the lifting assembly 3 raises and lowers the parking seat 9, the movable plate 11, and the vehicle hydrogen tank 6. The L-shaped rod 507 moves from bottom to top, pushing the long plate and the connecting plate 514 to open the port of the first connecting pipe 501. The rubber slider 508 slides with the slot 509. The insert plate 510 is inserted into the inside of the connecting plate 514 to seal the port of the first connecting pipe 501. Then, under the push of the U-shaped frame 504 on the bottom pressure block 513 and the movable plate 512, the second connecting pipe 505 is gradually opened, allowing the hydrogen from the vehicle hydrogen tank 6 to flow to the pressure tank 7. The second spring 511 and the first spring 503 play a reset role. The reset spring 401 and the limiting block 402 limit the movable plate 11 to prevent it from falling.
