[0028] The present utility model provides a vibration isolation structure for a vehicle-mounted hydrogen storage cylinder as shown in Figures 1 to 7 and includes:

[0029] A bottom plate 1, on the top end of the bottom plate 1 is fixedly provided with a vibration isolation rubber pad 2, on the top end of the bottom plate 1 is fixedly provided with a fixed frame 14, the bottom end of the vibration isolation rubber pad 2 is fixedly arranged inside the fixed frame 14, on the top end of the vibration isolation rubber pad 2 is fixedly provided with a mounting fixing plate 3, on the top end of the mounting fixing plate 3 is provided with a hydrogen storage cylinder 4, and a placement groove 5 is opened on the top end of the mounting fixing plate 3, and the bottom end of the hydrogen storage cylinder 4 is arranged inside the placement groove 5;

[0030] A rhombic groove 6 is opened on the top end of the vibration isolation rubber pad 2, on the bottom end of the mounting fixing plate 3 is fixedly provided with a rhombic block 7, the rhombic block 7 is fixedly arranged inside the rhombic groove 6, and a plurality of spring grooves 15 are opened inside the rhombic groove 6, and vibration isolation springs 16 are arranged inside the spring grooves 15;

[0031] The clamping assembly includes two arc-shaped clamping plates 8 provided at the top end of the mounting fixed plate 3. An anti-slip pad 9 is fixedly provided at the inner end of the arc-shaped clamping plate 8. The inner ends of the two anti-slip pads 9 are in contact with the outer end of the hydrogen storage cylinder 4. The bottom end of the arc-shaped clamping plate 8 is connected with an adjusting assembly. The adjusting assembly includes two T-shaped sliding grooves 10 opened at the top end of the mounting fixed plate 3. A T-shaped sliding block 11 is arranged inside the T-shaped sliding groove 10. The top ends of the two T-shaped sliding blocks 11 are respectively fixedly connected with the bottom ends of the two arc-shaped clamping plates 8. A first threaded rod 12 is arranged inside the T-shaped sliding groove 10. One end of the first threaded rod 12 passes through the T-shaped sliding block 11 and is threadedly connected with the T-shaped sliding block 11. Both ends of the first threaded rod 12 are rotatably connected with both ends inside the T-shaped sliding groove 10. One end of each of the two first threaded rods 12 extends to both sides of the mounting fixed plate 3 and is fixedly provided with a turntable 13.

[0032] Two limiting rods 17 are provided at the front end of the mounting fixed plate 3. A limiting groove 18 is opened at the front end of the T-shaped sliding block 11. One end of the limiting rod 17 passes through the mounting fixed plate 3 and extends into the inside of the limiting groove 18. The other ends of the two limiting rods 17 are fixedly provided with a connecting movable plate 19. A second threaded rod 20 is rotatably connected to the front end of the mounting fixed plate 3. One end of the second threaded rod 20 passes through the middle of the connecting movable plate 19 and extends to the front side of the connecting movable plate 19.

[0033] Use bolts to fix the bottom plate 1 inside the car trunk. Place the hydrogen storage cylinder 4 inside the placement groove 5 at the top end of the mounting fixed plate 3. Rotate the turntable 13. The turntable 13 drives the first threaded rod 12 to rotate. Since the first threaded rod 12 is threadedly connected with the T-shaped sliding block 11, the T-shaped sliding block 11 moves towards the hydrogen storage cylinder 4 as the first threaded rod 12 rotates. The T-shaped sliding block 11 drives the arc-shaped clamping plate 8 and the anti-slip pad 9 to move towards the hydrogen storage cylinder 4. The two arc-shaped clamping plates 8 and the anti-slip pad 9 will clamp and limit the outer end of the hydrogen storage cylinder 4. Then rotate the rotating block 21. The rotating block 21 drives the second threaded rod 20 to rotate. Since the second threaded rod 20 is threadedly connected with the connecting movable plate 19, the connecting movable plate 19 moves towards the mounting fixed plate 3 as the second threaded rod 20 rotates. The connecting movable plate 19 drives one end of each of the two limiting rods 17 to be inserted into the limiting grooves 18 on the two T-shaped sliding blocks 11 respectively. When the car is driving, starting, and braking, the vibration and shaking force on the car will first pass through the buffering of the vibration isolation rubber pad 2 and the multiple vibration isolation springs 16, so that the mounting fixed plate 3 and the hydrogen storage cylinder 4 can be vibration-isolated from all around.

[0034] The utility model clamps and fixes the hydrogen storage cylinder 4 on the installation fixing plate 3 through a clamping component, so that the hydrogen storage cylinder 4 is fixed firmly. A vibration isolation rubber pad 2 is fixedly connected between the installation fixing plate 3 and the bottom plate 1. The vibration isolation rubber pad 2 can separate the vibration and shaking generated by the vehicle, effectively avoiding the situation that the hydrogen storage cylinder 4 shakes and displaces greatly as the vehicle travels. The effect of fixing and vibration isolation is good. This embodiment specifically solves the problem existing in the prior art that when the on-vehicle hydrogen storage cylinder is installed and fixed inside the trunk of the vehicle, most of them are fixed by straps. Such a fixing method is not firm enough, the hydrogen storage cylinder is easy to shake with the vehicle, and it is easy to displace when the vehicle starts and brakes, and the effect of fixing and vibration isolation is not good enough.

[0035] Only some exemplary embodiments of the present utility model are described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
