Description

Technical Field

[0002] Hydrogen storage bottles for hydrogen vehicles are key components designed for hydrogen fuel cell vehicles and are used to store and supply hydrogen. Such hydrogen storage bottles play a vital role in hydrogen vehicles. They not only need to have the characteristics of high safety, high pressure and high hydrogen storage density, but also need to be able to adapt to various complex working environments.

[0003] In current hydrogen vehicle technology, hydrogen storage bottles are key energy storage devices, and their safety and stability are of vital importance.

The internal structure of the protective ring 3 10 is the same as that of the protective ring 1 5, and is also threadedly connected to the outer side of the hydrogen storage bottle body 2 3.

[0023] Specifically, Figure 5 As shown, the inner sides of the protective ring 15 and the protective ring 29 are slidably connected with a heat shield 11, and the upper and lower ends of the heat shield 11 are connected with guide columns 12, the outer diameter of the guide columns 12 is smaller than the cross-sectional inner diameter of the annular guide groove 8, and the heat shield 11 can perform circular motion around the hydrogen storage bottle body 1 in the middle space between the protective ring 15 and the protective ring 29, so as to facilitate fine-tuning of the protective position.

[0024] Specifically, Figure 6As shown, the inner side of the heat insulation cover 11 is connected to a connecting plate 13, and a snap-in groove 14 is provided inside the connecting plate 13, a fixing screw 15 is connected to the top of the rear end of the connecting plate 13, and an elastic limiting rod 16 is connected to the bottom of the rear end of the connecting plate 13, and a rotating heat insulation plate 17 is rotatably connected to the inner side of the connecting plate 13, a heat insulation cover 2 18 is arranged on the inner side of the protective ring 3 10, and a connecting plate 2 19 is connected to the inner side of the heat insulation cover 2 18, a snap-in block 20 is connected to the inner side of the connecting plate 2 19, and a telescopic rod 1 21 is connected to the inner side of the snap-in block 20, and a pushing block 22 is connected to the rear end of the connecting plate 2 19, After rotating, the connecting plate 19 contacts the connecting plate 1 13, passes through the inside of the clamping groove 14 through the clamping block 20, and then is clamped on the outside of the connecting plate 1 13 under the elastic force of the telescopic rod 1 21.

When the connecting plate 1 13 and the connecting plate 2 19 are connected, the pushing block 22 pushes the rotating heat insulation plate 17 to rotate ninety degrees, passing through the hollow position of the connecting plate 2 19, so that the rotating heat insulation plate 17 is in the middle of the heat insulation cover 1 11 and the heat insulation cover 2 18 for blocking.

[0025] The upper and lower ends of the outer side of the hydrogen storage bottle body 1 are provided with a pressing positioning assembly, and the pressing positioning assembly includes a positioning plate 23, and the inner side of the positioning plate 23 is provided with an oblique push extrusion block 29, the right side of the positioning plate 23 is provided with a positioning plate 22, and the inner side of the positioning plate 22 is connected with an upper oblique push plate 35, and the pressing positioning assembly is used for the connection and positioning between the hydrogen storage bottle body 1 and the hydrogen storage bottle body 23.

[0026] Specifically, Figure 8 As shown, one side of the protective ring 5 is connected to a positioning plate 23, and a T-shaped slot 28 is provided inside the positioning plate 23. The top of the positioning plate 23 is connected to a fixed pressure plate 24. The T-shaped slot 28 is used to clamp and fix the T-shaped block 33. Then the fixed pressure plate 24 restricts the connection of the top of the T-shaped block 33 to improve the stability of the connection.

[0027] Specifically, Figure 8 As shown, the front and rear ends of the positioning plate 23 are connected to side clamp frames 25, and the inner side of the side clamp frame 25 is connected to a movable plate 26, one end of the movable plate 26 is connected to a telescopic rod 27, and the extrusion limit plate 34 is squeezed downward to push the movable plate 26 to compress the spring on the outside of the telescopic rod 27. When the extrusion limit plate 34 is at the bottom of the movable plate 26, the movable plate 26 resets to limit the top movement of the extrusion limit plate 34, and the up and down adjustment of the extrusion limit plate 34 is limited by the combination of the side clamp frame 25 and the movable plate 26.

[0028] Specifically, Figure 7As shown, the inner side of the positioning plate 23 is slidably connected with an oblique push extrusion block 29, and the inner side of the oblique push extrusion block 29 is connected with a guide elastic rod 30, and one end of the oblique push extrusion block 29 is connected with a rubber pad 31. After being squeezed, the oblique push extrusion block 29 slides inward, driving the rubber pad 31 to press the outer wall of the hydrogen storage bottle body 1, thereby improving the stability of the supporting connection.

[0030] In this embodiment: a heat insulation cover 11 and a heat insulation cover 2 18 are arranged between the hydrogen storage bottles for heat insulation protection to avoid the stable mutual influence of individual components. While the heat insulation support is connected, the middle part is blocked by rotating the heat insulation plate 17 to improve the protection performance between the hydrogen storage bottles. A relatively appropriate spacing is required between the hydrogen storage bottles. The positioning plate 1 23 and the positioning plate 2 32 are mutually clamped and fastened with screws after pre-fixation. At the same time, the oblique push extrusion block 29 is pushed to squeeze the outer wall of the hydrogen storage bottle during the clamping to improve the stability of the connection.

[0031] The specific scheme is as follows: during the installation of the hydrogen storage bottle, the protective ring 1 5 and the protective ring 2 9 are screwed on the outer side of the hydrogen storage bottle body 1 in sequence, and then the inner side is clamped into the heat insulation cover 11, and the outer side of the hydrogen storage bottle body 2 3 is also fixed with the protective ring 3 10 and the heat insulation cover 2 18 in sequence. For the fixation between the hydrogen storage bottle body 1 and the hydrogen storage bottle body 2 3, the positioning plate 1 23 and the positioning plate 2 32 are connected, and then the T-shaped card block 33 is clamped in the T-shaped card slot 28. At this time, the upper inclined push plate 35 is pressed down to push the inclined push. The pressing block 29 moves inward, and under the elastic connection of the guiding elastic rod 30, the rubber pad 31 can be closely attached to the hydrogen storage bottle body 1, and the stability of the connection is improved by the support of the reverse force. When the positioning plate 22 is inserted, the limiting plate 34 is squeezed to squeeze the movable plate 26. After the oblique displacement, the side clamp frame 25 and the movable plate 26 are limited up and down. At this time, the positioning plate 1 23 and the positioning plate 2 32 are tightly pressed and fixed, and then connected by the screws of the fixing plate 24, the T-shaped clamp 33 is limited from falling off the top. The T-shaped card slot 28 is separated from the connection stability. After the spacing control installation, the heat insulation cover 11 and the heat insulation cover 2 18 can be rotated to be close to each other, and then the clamping block 20 passes through the inside of the clamping slot 14, and is clamped on the outside of the connecting plate 13 under the elastic force of the telescopic rod 1 21. At this time, the hole at the bottom end of the clamping block 20 is pushed into the limit by the elastic limiting rod 16, and the top end is screwed in and fixed by the fixing screw 15, so that the connecting plate 13 is fixedly connected. When the connecting plate 13 and the connecting plate 2 19 are connected, The pushing block 22 pushes the rotating heat insulation plate 17 to rotate ninety degrees and passes through the hollow position of the connecting plate 2 19, so that the rotating heat insulation plate 17 is located in the middle of the heat insulation cover 11 and the heat insulation cover 2 18 for blocking, so that three layers of heat insulation protection, namely the heat insulation cover 11, the rotating heat insulation plate 17 and the heat insulation cover 2 18, are arranged between the hydrogen storage bottle body 1 and the hydrogen storage bottle body 2 3 to reduce the influence of the temperature between different hydrogen storage bottles. The materials used for the heat insulation cover 11, the rotating heat insulation plate 17 and the heat insulation cover 2 18 are all aerogel.
