The mounting slot 31 plays a positioning role in positioning the hydrogen bottle 5. The buffer pad 32 makes the contact between the hydrogen bottle 5 and the carrier plate 3 elastic and can play a buffering role.

The load-bearing plate 3 is provided with a clamping assembly 6 that is in close contact with the front and back of multiple hydrogen bottles 5. The top of the base plate 1 is provided with a lifting assembly 7. The lifting assembly 7 is provided with a plurality of clamping assemblies 6 that are in close contact with the tops of the hydrogen bottles 5. A telescopic rod 9 is provided between the pressing assembly 8, the lifting assembly 7 and the base plate 1.

Please refer to Figures 1 and 2. The buffer assembly 4 in this embodiment includes a sliding rod 41 that is slidingly connected to the top of the base plate 1. The longitudinal section of the sliding rod 41 is T-shaped. The top of the base plate 1 is provided with a sliding rod 41 that is suitable for the sliding rod 41. The T-shaped chute 11 equipped with the T-shaped chute 11 restricts the sliding rod 41 so that the sliding rod 41 can stably slide left and right on the bottom plate 1. The sliding rod 41 will not separate from the bottom plate 1. The top of the sliding rod 41 A trapezoidal block 42 is fixedly connected. The opposite sides of the two trapezoidal blocks 42 are both fixedly connected to a second spring 43. The side of the second spring 43 away from the trapezoidal block 42 is fixedly connected to a fixed plate 44 fixedly connected to the top of the bottom plate 1. , the opposite sides of the two trapezoidal blocks 42 are fixedly connected to a fixed rod 45 that is slidingly connected to the inner cavity of the fixed plate 44, and the opposite sides of the two trapezoidal blocks 42 are both slidably connected to a connecting rod fixedly connected to the bottom of the load-bearing plate 3 46.

Please refer to Figures 1, 2, 3 and 4. The clamping assembly 6 in this embodiment includes a support plate 61 fixedly connected to the top of the load-bearing plate 3. The back of the support plate 61 is rotatably connected to the support through a bearing. The rotating shaft 62 on the front of the plate 61 and the back of the rotating shaft 62 are fixedly connected with a first handle 63. The first handle 63 is used to drive the rotation of the rotating shaft 62. The outer surface of the rotating shaft 62 is threadedly connected with a mounting plate 64. The back of the mounting plate 64 A plurality of sleeves 65 that are in close contact with the front of the hydrogen cylinder 5 are fixedly connected. A plurality of gas sensors 66 located in the inner cavities of the plurality of sleeves 65 are fixedly connected to the back of the mounting plate 64. The plurality of gas sensors 66 are connected to the plurality of sleeves. The barrels 65 are arranged in a one-to-one correspondence. The front side of the mounting plate 64 is fixedly connected with a limiting rod 67 that is slidingly connected to the inner cavity of the bearing plate 3. The front side of the bearing plate 3 is provided with a limiting hole that matches the limiting rod 67. The sliding of the limiting rod 67 and the limiting hole causes the suspended mounting plate 64 to slide forward or backward on the rotating shaft 62 instead of following the rotation of the rotating shaft 62 .

When the rotating shaft 62 is rotated, the mounting plate 64 moves backward on the rotating shaft 62 through the threaded connection, so that the sleeve 65 is in close contact with the front of the hydrogen bottle 5 and cooperates with the supporting plate 61 to clamp the hydrogen bottle 5 Tightly fixed.

The lifting assembly 7 includes a drive shaft 71 that is rotatably connected to the top of the base plate 1 . The outer surface of the drive shaft 71 is threadedly connected to a connecting plate 72 . The telescopic rod 9 includes a hollow rod that is fixedly connected to the top of the base plate 1 . The inner cavity of the hollow rod is slidably connected. There is a solid rod fixedly connected to the bottom of the connecting plate 72. The telescopic rod 9 is arranged so that when the driving shaft 71 rotates, the connecting plate 72 will not follow the rotation, but will move up and down.

The pressing assembly 8 includes a third spring 81 fixedly connected to the top of the connecting plate 72. The top of the third spring 81 is fixedly connected to a baffle 82, and the bottom of the baffle 82 is fixedly connected to a bottom penetrating third spring 81 and extending to the connecting plate. The vertical rod 83 at the bottom of 72 is fixedly connected with a splint 84 that is in close contact with the top of the hydrogen bottle 5.

In this embodiment, after the sleeve 65 cooperates with the support plate 61 to clamp and fix the hydrogen bottle 5, the driving shaft 71 is rotated to cause the connecting plate 72 to move downward, so that the clamping plate 84 is in close contact with the top of the hydrogen bottle 5. When it continues to descend, This will cause the third spring 81 to gradually stretch, and at the same time the first spring 2 component will compress, so that during bumps, the elastic force of the first spring 2 and the third spring 81 can always keep the hydrogen bottle 5 clamped and fixed, and at the same time act as a buffer. effect.

It should be noted that the plurality of sleeves 65 are arranged in a one-to-one correspondence with the plurality of hydrogen bottles 5. The sleeves 65 are slidably connected to the outer surface of the valve of the hydrogen bottle 5. The front of the hydrogen bottle 5 has a valve, and the barrel of the sleeve 65 is The shape can properly clamp the hydrogen bottle 5 and at the same time achieve a relatively sealed environment. Whether there is leakage of the hydrogen bottle 5 can be detected through the gas sensor 66 .

The working principle of the above embodiment is:

When in use, the hydrogen bottle 5 is placed on the buffer pad 32 in the mounting groove 31 on the bearing plate 3. The mounting groove 31 plays a positioning role for the hydrogen bottle 5, and the buffer pad 32 can play a certain buffering role. A handle 63 drives the rotation of the rotating shaft 62, and under the sliding restriction of the limit rod 67 in the inner cavity of the limit hole, the mounting plate 64 moves backward, so that the sleeve 65 is sleeved on the outer surface of the hydrogen cylinder 5 valve, and cooperates with the support The plate 61 clamps and fixes the hydrogen bottle 5, which can prevent the hydrogen bottle 5 from falling off during transportation. Turning the second handle 73 drives the rotation of the drive shaft 71, so that the connecting plate 72 descends under the restriction of the telescopic rod 9, so that the splint 84 gradually Make close contact with the top of the hydrogen bottle 5. After contact, continue to rotate the second handle 73 to stretch the third spring 81. At the same time, the first spring 2 is also in a compressed state, further clamping and fixing the hydrogen bottle 5.

When bumps are encountered during transportation, the first spring 2 in the compressed state and the third spring 81 in the stretched state use their own elasticity and deformation to cause the clamping plate 84 and the load-bearing plate 3 to always clamp and fix the hydrogen bottle 5, while the overall clamping The tight assembly 6 slides up and down following the load-bearing plate 3, which can always keep the hydrogen bottle 5 and the load-bearing plate 3 fixed. At the same time, the connecting rod 46 follows and slides up and down, squeezing the two trapezoidal blocks 42 so that the two trapezoidal blocks 42 are opposite or opposite. The back movement causes the second spring 43 to compress or stretch, thereby playing a good buffering effect on the hydrogen bottle 5, and the first spring 2, the second spring 43 and the third spring 81 dampen each other, so that the load plate can be loaded. The hydrogen bottle 5 on 3 quickly returned to stability, and the overall structure achieved the purpose of having a good buffering effect for the hydrogen bottle transportation fixture of hydrogen energy-powered vehicles, which can effectively improve the safety performance during transportation.
