[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] Please refer to Figure 1 - Figure 4 As shown in the figure, the present invention is a safety hydrogen storage device for a hydrogen energy vehicle, including a mounting base 1. An upper sealing door 5 is slidably arranged above the side of the mounting base 1, and a lower sealing door 3 adapted to the upper sealing door 5 is slidably arranged below the side of the mounting base 1. A mounting support plate 2 is arranged at the bottom inside the mounting base 1, an upper mounting fixing plate 4 is arranged above the inside of the mounting base 1, and end fixing seats 6 are symmetrically arranged at both ends inside the mounting base 1. A support arc surface groove 60 is formed on the opposite side of the two end fixing seats 6. A plurality of end fixing springs 61 are arranged in an annular array in the support arc surface groove 60, and an end fixing damper 62 is arranged in the middle of the end fixing springs 61. The mounting base 1 is installed inside the vehicle body, then the hydrogen storage tank is placed on the mounting support plate 2 inside the mounting base 1 and fixed by the upper mounting fixing plate 4. At the same time, both ends of the hydrogen storage tank are fixed by the symmetrically arranged end fixing seats 6 at both ends, effectively ensuring the stability of the hydrogen storage tank, and it is convenient to replace and install.

[0028] Among them, a plurality of lower support springs 21 are arranged at the bottom inside the mounting base 1, and a lower support damper 22 is arranged in the middle of the lower support springs 21. The mounting support plate 2 is arranged on the lower support springs 21;

[0029] In addition, several upper mounting cylinders 40 are arranged at the top inside the mounting base 1. A upper fixing spring 41 is fixedly arranged at the extending end of the several upper mounting cylinders 40. A upper fixing damper 42 is arranged in the middle of the upper fixing spring 41. The upper mounting fixing plate 4 is fixedly arranged at the end of the upper fixing spring 41. And rubber blocks 43 are respectively arranged on the opposite sides of the mounting support plate 2 and the upper mounting fixing plate 4.

[0030] After the hydrogen storage tank is placed on the mounting support plate 2 inside the mounting base 1, with the pressing and fixing of the upper mounting fixing plate 4, at the same time, a lower support spring 21 is arranged below the mounting support plate 2, and the upper part of the upper mounting fixing plate 4 is connected to the upper mounting cylinder 40 through the upper fixing spring 41, effectively fixing the hydrogen storage tank and avoiding the occurrence of unsafe situations caused by bumps during vehicle driving.

[0031] In addition, referring to Figure 2 As shown, adjusting main grooves 11 are symmetrically opened at both ends inside the mounting base 1. A number of adjusting screw holes 12 are symmetrically opened on both sides inside the mounting base 1 and on both sides of the adjusting main grooves 11. An end fixing bracket 65 is slidably arranged in the adjusting main groove 11. An end fixing screw 64 is threadedly connected to the end of the end fixing bracket 65. A fixing ring 641 is arranged at the end of the end fixing screw 64. The fixing ring 641 is rotatably connected to the end connecting block 63 on the side of the end fixing seat 6.

[0032] Side brackets 651 are symmetrically arranged on both sides of the end fixing bracket 65. The side brackets 651 are fixed to the mounting base 1 through fixing bolts 652.

[0033] After the hydrogen storage tank is fixed between the mounting support plate 2 and the upper mounting fixing plate 4, the height of the end fixing seat 6 can be adjusted by adjusting the end fixing bracket 65 to align the center of the end fixing seat 6 with the center of the hydrogen storage tank. Then, the fixing ring 641 can be rotated, and the two ends of the hydrogen storage tank are squeezed and fixed by pushing the end fixing seat 6. At this time, the hydrogen storage tank is fixed in multiple directions, effectively ensuring the stability of the hydrogen storage tank in the vehicle.

[0034] It should be noted that the control of the end fixing seat 6 is to make the end fixing screw 64 move outwards by rotating the fixing ring 641, thereby pushing the end fixing seat 6 to fix the hydrogen storage tank. Similarly, the upper mounting fixing plate 4 located above can also be changed to the same control structure as the end fixing seat 6, and the specific design can be improved according to the situation.

[0035] Referring to Figure 1 and Figure 4As shown, in order to ensure that the temperature inside the mounting base 1 is at a relatively low level, a cooling fan 13 is provided at one end of the mounting base 1, and an air passing net 131 is provided at the other end of the mounting base 1. The cooling fan 13 can cool the environment inside the mounting base 1 to ensure that the hydrogen storage tank is in a relatively low state.

[0036] Referring to Figure 1 and Figure 3 As shown, an upper hidden cavity 501 is formed above the mounting base 1. The upper sealing door 5 is slidably arranged in the upper hidden cavity 501, and an upper slider 50 is arranged on one side inside the upper hidden cavity 501.

A lower connecting block 31 is arranged on the other side of the lower sealing door 3. After the hydrogen storage tank is fixedly placed inside the mounting base 1, it can be sealed through the upper sealing door 5 and the lower sealing door 3. When the mounting base 1 is arranged at the rear of the vehicle, it may be located inside the trunk. At this time, in order to prevent the items in the trunk from affecting the hydrogen storage tank, the upper sealing door 5 and the lower sealing door 3 are fixedly connected by bolts, so that the hydrogen storage tank can be well protected, avoiding the situation that the hydrogen storage tank is knocked by other items during the use of the vehicle. The overall structure is simple, and during the use of the vehicle, it is convenient to replace the hydrogen storage tank, saving the time for hydrogen replacement.

[0037] Finally, a pipe passing hole 10 is arranged on one side of the mounting base 1 for connecting the pipeline for supplying hydrogen energy to the vehicle.

[0038] In summary, after the hydrogen storage tank is placed on the mounting support plate 2 inside the mounting base 1, it is cooperatively fixed by the pressing of the mounting fixing plate 4. At the same time, the two ends of the hydrogen storage tank are squeezed and fixed by the fixing seat 6, so that the hydrogen storage tank is fixed in multiple directions, effectively ensuring the stability of the hydrogen storage tank inside the vehicle. Moreover, the upper sealing door 5 and the lower sealing door 3 are fixedly connected by bolts, so that the hydrogen storage tank can be well protected, avoiding the situation that the hydrogen storage tank is knocked by other items during the use of the vehicle. The overall structure is simple, and during the use of the vehicle, it is convenient to replace the hydrogen storage tank, saving the time for hydrogen replacement.

[0039] The working principle of the present invention:

[0040] In use, open the upper sealing door 5 and the lower sealing door 3, then place the hydrogen storage tank on the mounting support plate 2 within the mounting seat 1. Then, activate the upper mounting cylinder 40. The upper mounting cylinder 40 extends downward, controlling the downward movement of the upper mounting fixing plate 4 to fix the hydrogen storage tank. Then, according to the central height of the hydrogen storage tank, adjust the position of the end fixing bracket 65 so that the center line of the end fixing seat 6 coincides with the center line of the hydrogen storage tank. Then, manually rotate the fixing ring 641 so that the end fixing screw 64 moves outward, thereby squeezing and fixing both ends of the hydrogen storage tank by pushing the end fixing seat 6. After the fixing is completed, connect the pipeline for supplying hydrogen to the hydrogen storage tank, and then close the upper sealing door 5 and the lower sealing door 3.

[0041] The above has described in detail one embodiment of the present invention, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention.
