[0026] like Figures 1-5As shown, this embodiment provides a hydrogen storage module test bench 1 for a vehicle fuel cell engine, including a test bench 1, which consists of a frame and acrylic plates. The acrylic plates are fixed together by locking blocks for easy quick installation and disassembly. The tabletop of the test bench 1 is an anti-static work surface. A mounting base 2 is installed in the middle of the surface of the test bench 1, on which the workpiece to be tested is placed. A test component is provided on one side of the mounting base 2, which tests the workpiece to be tested. A power distribution box 3 is installed on one side of the test bench 1. The test component is an existing testing equipment. Both the test component and the power distribution box 3 are existing technologies and are not particularly limited here. A placement slot 4 is opened on the other side of the test bench 1. A cabinet door 5 is hinged to the outer side of the bottom of the placement slot 4, and the placement slot 4 is opened and closed through the cabinet door 5. The cabinet door 5 has a locking groove 13 at its upper end, and a locking rod 14 is movably installed on the top of the placement groove 4, with the locking rod 14 and the locking groove 13 being compatible. The placement groove 4 has a sliding groove 15 at its upper end, and the locking rod 14 is slidably installed in the sliding groove 15. A spring 16 connects the inner wall of the sliding groove 15 and the locking rod 14. By pulling up the locking rod 14, the locking rod 14 is moved out of the locking groove 13, thereby unlocking the cabinet door 5. When the locking rod 14 is released, the locking rod 14 slides in the sliding groove 15 due to the return action of the spring 16, so that the locking rod 14 is inserted into the locking groove 13, thereby locking the cabinet door 5.

[0027] like Figure 2 As shown, slide rails 6 are installed on both sides of the placement groove 4. A placement base 7 is slidably mounted on the slide rails 6. A fixing mechanism is provided on the placement base 7 to fix the hydrogen fuel tank on the placement base 7. The fixing mechanism includes a clamping rod 8 hinged to one side of the placement base 7. A connecting block 9 is fixed to one end of the clamping rod 8. A slot 10 adapted to the connecting block 9 is opened on the other side of the placement base 7. Limiting slots 11 are symmetrically opened on both sides of the slot 10. A limiting block 12 is rotatably mounted on the connecting block 9. The clamping rod 8 is arc-shaped and adapted to the shape of the hydrogen fuel tank. By rotating the clamping rod 8, the hydrogen fuel tank is clamped on the placement base 7. The connecting block 9 is inserted into the slot 10. By rotating the limiting block 12, both ends of the limiting block 12 are rotated into the limiting slot 11, thereby fixing the clamping rod 8.

[0028] A linkage mechanism is provided between the inner side of the cabinet door 5 and the placement base 7. This linkage mechanism is used to pull the placement base 7 to slide. The linkage mechanism includes a connecting seat 17 and a connecting rod 18. The connecting seats 17 are respectively located on the inner side of the cabinet door 5 and at both ends of the placement base 7. Rotating shafts are installed at both ends of the connecting rod 18, and the two ends of the connecting rod 18 are rotatably connected to the connecting seats 17 on the cabinet door 5 and the placement base 7, respectively, through the rotating shafts. When the cabinet door 5 is opened, the cabinet door 5 pulls the placement base 7 on the slide rail 6 via the connecting rod 18, moving the placement base 7 from the placement slot 4 to the outside, allowing the operator to operate from the outside, greatly improving the convenience of operation.

[0029] like Figure 4 As shown, a mounting groove 19 is provided in the middle of the bottom of the placement groove 4. A support plate 20 is hinged in the mounting groove 19. Connecting rods 21 are installed on both sides of the other end of the support plate 20. A connecting groove 22 is provided on the inner side of the cabinet door 5. The support plate 20 is slidably set in the connecting groove 22 through the connecting rods 21. When the cabinet door 5 is opened, the connecting rods 21 drive the support plate 20 to rotate in the connecting groove 22. The other end of the support plate 20 rotates in the mounting groove 19, so that the support plate 20 supports the sliding placement base 7 from below, improving the stability of the placement base 7. In addition, the support plate 20 limits the cabinet door 5 to prevent the cabinet door 5 from pulling the placement base 7 off the slide rail 6, improving the safety of use.

[0030] The cabinet door 5 is equipped with a gas supply connector 23, which is used to connect to the gas pipe of the hydrogen fuel tank. The gas supply connector 23 is connected to the test component through the corrugated gas supply pipe 24. The gas supply connector 23 is set on the cabinet door 5 to make it more convenient for operators to operate.

[0031] In use, by opening the cabinet door 5, the cabinet door 5 pulls the placement base 7 on the slide rail 6 from inside the placement slot 4 to the outside via the connecting rod 18. Simultaneously, the cabinet door 5 pulls the support plate 20 in the connecting slot 22 via the connecting rod 21. The other end of the support plate 20 flips in the mounting slot 19. When the support plate 20 flips to a horizontal position, it adheres to the underside of the placement base 7, providing support for the moved placement base 7 from below. The hydrogen fuel tank is then placed on the placement base 7, and the clamping rod 8 is flipped to clamp and fix the hydrogen fuel tank in place. Place the base 7, and insert the other end of the clamping rod 8 into the slot 10 through the connecting block 9. Rotate the limiting block 12 into the limiting groove 11 to fix the hydrogen fuel tank. After fixing, connect the gas delivery tank of the hydrogen fuel tank to the gas delivery connector 23. After installation, close the cabinet door 5. The connecting rod 18 pushes the base 7 to slide into the placement groove 4 on the slide rail 6. After the cabinet door 5 is closed, the locking rod 14 slides in the sliding groove 15 through the reset action of the spring 16, so that the locking rod 14 is inserted into the locking groove 13 on the cabinet door 5, thereby locking the cabinet door 5.
