A number of protrusions are fixedly connected to the side wall of the ring block six. An edge opening adapted to the prism five is reserved on the ring block six. The prism five extends into the ring block six and the ring mouth through the edge opening. A ring piece five that engages with the ring block six is screwed in the ring mouth.

[0007] A receiving opening is reserved inside the pressing block. The part of the pressing block farther from the prism four is curved. The part of the pressing block farther from the prism four plugs a leather cover. A pair of water guiding channels are reserved on the prism four. A check valve is installed in the water guiding channels. The check valves in the pair of water guiding channels direct the water-like medium in opposite directions. The receiving opening is filled with a water-like medium.

[0008] The pressing unit is circular.

[0009] The part of the prism four closer to the spiral beryllium copper wire is fixedly connected to a connecting cover wound in a spiral shape. The connecting cover includes a wire wound in a spiral shape. The part of the plug closer to the spiral beryllium copper wire is fixedly connected to a connecting block corresponding to the connecting cover wound in a spiral shape.

[0010] A water-like medium is installed in the chamber between the plug and the prism four.

[0011] A number of outer covers are screwed to the side wall of the pressing unit at a position closer to the prism five. The outer covers correspond to the prism five.

[0012] A rotating piece is fixedly connected to the outer cover. A dialing block is fixedly connected to the part of the rotating piece farther from the outer cover.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. Through the installation of the ring piece four and the ring block four, under the drive of the motor, a number of fifth ring covers are rotated, causing a number of linkage bars to protrude to press against the hydrogen storage bottle. While protecting the hydrogen storage bottle from being damaged by pressing, it is beneficial to make the pressing strength of a number of linkage bars consistent, improving the pressing efficiency for hydrogen storage bottles of different sizes.

[0015] 2. In the present invention, several linkage bars and pressing blocks are first attached to the hydrogen storage bottle, and then the prism four presses the pressing blocks through the connecting bar and the spiral beryllium copper wire, strengthening the tightness of the pressing blocks against the hydrogen storage bottle. The length of the spiral beryllium copper wire becomes shorter, which is conducive to the operator identifying the tightness strength of the pressing blocks according to the shortening degree of the length of the prism five, facilitating the operator to control the tightness strength against the hydrogen storage bottle, so as to protect the hydrogen storage bottle from being damaged by pressing and squeezing.

[0016] 3. When the connecting block in the present invention moves cyclically in the wire wound in a spiral shape, an electromotive force appears in the wire wound in a spiral shape. The medium that promotes the movement of electrons by the electromotive force in turn inhibits the movement of the connecting block. The medium that promotes the movement of electrons by the electromotive force has the radiation property of wave particles. A water-like medium is installed in the chamber between the plug and the prism four. Affected by the medium, the water-like medium will quickly convert from a water-like state to a state with closely packed molecules and the least kinetic energy. Therefore, the connecting block makes the water-like medium viscous, which is conducive to reducing the amplitude of the pressing block. Through the spiral beryllium copper wire, it is conducive to reducing the amplitude of the prism four. The connecting block makes the water-like medium viscous, which is conducive to reducing the amplitude of the pressing block. During the vibration stage of the pressing block, the connecting block moves cyclically in the connecting cover wound in a spiral shape, causing the medium that inhibits the movement of the connecting block to appear in the connecting cover wound in a spiral shape, which is conducive to reducing the amplitude of the pressing block, weakening the vibration of the hydrogen storage bottle during the vehicle driving stage, and facilitating maintaining the pressing strength of the pressing unit against the hydrogen storage bottle during the vibration stage of the hydrogen storage bottle.

[0017] 4. In the present invention, the hydrogen storage bottle is placed in the pressing unit. The driving head of the motor rotates the ring piece four through the ring block five, the ring piece four rotates the ring block four, the ring block four rotates the ring cover five, the ring cover five moves the linkage bar, and the linkage bar presses the pressing block to squeeze against the hydrogen storage bottle. The operator rotates the rotating piece through the dial block, the rotating piece rotates the outer cover, the outer cover rotates the prism five, the prism five rotates the connecting bar through the connecting bar to move the connecting bar. The prism five moves in the outer cover, the connecting bar presses the plug to shorten the length of the spiral beryllium copper wire, the spiral beryllium copper wire presses the prism four, and then presses against the hydrogen storage bottle through the pressing block. By the shortening degree of the length of the spiral beryllium copper wire, the squeezing strength borne by the hydrogen storage bottle is identified, which is conducive to the operator identifying the tightness strength of the pressing block according to the shortening degree of the length of the prism five, facilitating the operator to control the tightness strength against the hydrogen storage bottle, so as to protect the hydrogen storage bottle from being damaged by pressing and squeezing, facilitating the pressing and limiting installation of several hydrogen storage bottles, facilitating the independent pressing and limiting operation for each hydrogen storage bottle, and improving the installation efficiency of the vehicle-mounted hydrogen storage bottle.

Detailed implementation manners

[0028] In order to make the objectives, technical solutions and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments of the present invention. The same reference numerals in the accompanying drawings represent the same components. It should be noted that the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0029] Refer to Figures 1 - 7, an embodiment of the present invention provides a vehicle-mounted hydrogen storage bottle installation device, which includes a support 3 located on a mounting base 2 and a pressing unit 4 fixedly connected to the support 3. The pressing unit 4 is circular, and there is a circular opening 5 reserved in the pressing unit 4. A fourth circular cover 7 is fixedly connected in the circular opening 5. A number of fifth circular covers 8 are screwed on the fourth circular cover 7. Spiral protrusions are fixedly connected to the inner wall surface of the fifth circular cover 8. A linkage rod 9 is screwed in the fifth circular cover 8. Spiral protrusions are fixedly connected to the side wall surface of the linkage rod 9. The part of the linkage rod 9 farther from the fifth circular cover 8 extends out of the side wall of the circular opening 5 and into the pressing unit 4. An operating block 10 is arranged at the part of the linkage rod 9 farther from the fifth circular cover 8. A fourth circular piece 6 is screwed on the side wall of the fourth circular cover 7. A number of protrusions are fixedly connected to the fourth circular piece 6. A fourth circular block 21 engaged with the fourth circular piece 6 is fixedly connected to the part of the fifth circular cover 8 closer to the fourth circular piece 6. A number of protrusions are fixedly connected to the side wall of the fourth circular block 21. A motor 22 is arranged between the inner side wall of the fourth circular cover 7 and the circular opening 5. The driving head of the motor 22 extends out of the fourth circular cover 7. A fifth circular block 23 engaged with the fourth circular piece 6 is fixedly connected to the driving head of the motor 22. A number of protrusions are fixedly connected to the side wall of the fifth circular block 23.

[0030] Through the arrangement of the fourth circular piece 6 and the fourth circular block 21, under the actuation of the motor 22, a number of fifth circular covers 8 are rotated, causing a number of linkage rods 9 to extend out to press the hydrogen storage bottle. In the case of protecting the hydrogen storage bottle from being damaged by pressing, it is beneficial to make the pressing strength of a number of linkage rods 9 consistent, improving the pressing efficiency for hydrogen storage bottles of different sizes.

[0031] There is an inner cavity reserved in the linkage rod 9. A fourth prism 24 is movably plugged at the part of the linkage rod 9 farther from the fifth circular cover 8. The operating block 10 is fixedly connected to the fourth prism 24. A plug 26 is connected to the part of the fourth prism 24 farther from the operating block 10 through a spiral beryllium copper wire 25. A connecting rod 27 is screwed on the part of the plug 26 farther from the spiral beryllium copper wire 25. Spiral protrusions are fixedly connected to the side wall surface of the connecting rod 27. The connecting rod 27 is screwed to the linkage rod 9. A fifth prism 28 is fixedly connected to the part of the connecting rod 27 farther from the plug 26. The fifth prism 28 extends out of the fifth circular cover 8 and the linkage rod 9. A sixth circular block 29 is screwed on the inner side wall of the circular opening 5 closer to a number of fifth prisms 28. A number of protrusions are fixedly connected to the side wall of the sixth circular block 29. A prism opening adapted to the fifth prism 28 is reserved on the sixth circular block 29. The fifth prism 28 extends into the sixth circular block 29 and the circular opening 5 through the prism opening. A fifth circular piece 210 engaged with the sixth circular block 29 is screwed in the circular opening 5. A number of protrusions are fixedly connected to the fifth circular piece 210.

[0032] First, several linkage bars 9 and pressing blocks 10 are attached to the hydrogen storage bottle. Then, through the connecting bar 27 and the helical beryllium copper wire 25, the prism four 24 presses the pressing block 10, strengthening the tightness of the pressing block 10 against the hydrogen storage bottle. The length of the helical beryllium copper wire 25 becomes shorter, which is conducive to the operator identifying the tightening strength of the pressing block 10 according to the shortening degree of the prism five 28, facilitating the operator to control the tightening strength on the hydrogen storage bottle to protect the hydrogen storage bottle from being damaged by pressing, facilitating the pressing and limiting installation of several hydrogen storage bottles, facilitating the independent pressing and limiting operation on each hydrogen storage bottle, and improving the installation efficiency of the vehicle-mounted hydrogen storage bottle.

[0033] A connecting cover 31 wound in a spiral shape is fixedly connected to the part of the prism four 24 closer to the helical beryllium copper wire 25. The connecting cover 31 includes a wire wound in a spiral shape. A connecting block 32 corresponding to the connecting cover 31 wound in a spiral shape is fixedly connected to the part of the plug 26 closer to the helical beryllium copper wire 25. The connecting block 32 always has the property of attracting substances such as iron, cobalt, and nickel. When the connecting block 32 moves back and forth in the wire wound in a spiral shape, an electromotive force appears in the wire wound in a spiral shape. The medium that promotes the movement of electrons by the electromotive force in turn inhibits the movement of the connecting block 32. The medium that promotes the movement of electrons by the electromotive force has the radiation property of wave particles. A water-like medium is installed in the chamber between the plug 26 and the prism four 24. Affected by the medium, the water-like medium will quickly change from a water-like state to a state with closely packed molecules and the least kinetic energy. Therefore, the water-like medium becomes viscous through the connecting block 32, causing the amplitude of the pressing block 10 to decrease. A containing port 33 is reserved in the pressing block 10. The part of the pressing block 10 farther from the prism four 24 is curved. A leather cover 34 is plugged at the part of the pressing block 10 farther from the prism four 24. A pair of water guiding channels 35 are reserved on the prism four 24. Check valves are installed in the pair of water guiding channels 35. The check valves in the pair of water guiding channels 35 cause the water-like medium to flow in opposite directions. A water-like medium is installed in the containing port 33.

[0034] The installation of the helical beryllium copper wire 25 is conducive to reducing the amplitude of the prism four 24. Through the connecting block 32, the water-like medium becomes viscous, causing the amplitude of the pressing block 10 to decrease. During the vibration stage of the pressing block 10, the connecting block 32 moves back and forth in the connecting cover 31 wound in a spiral shape, causing a medium that inhibits the movement of the connecting block 32 to appear in the connecting cover 31 wound in a spiral shape, causing the amplitude of the pressing block 10 to decrease, weakening the vibration of the hydrogen storage bottle during the vehicle's driving stage, and facilitating maintaining the pressing strength of the pressing unit 4 on the hydrogen storage bottle during the vibration stage of the hydrogen storage bottle.

[0035] On the side wall of the pressing unit 4, several outer covers 36 are rotatably connected to the part closer to the prism five 28. The outer covers 36 correspond to the prism five 28. A rotating piece 37 is fixedly connected to the outer cover 36, and a shifting block 38 is fixedly connected to the part of the rotating piece 37 farther from the outer cover 36. The outer cover 36 has the property of transmitting light, which is conducive to the operator to identify the pressing strength of the pressing unit 4. Through the installation of the shifting block 38, it is conducive to the operator to rotate the prism five 28, or the outer cover 36 can be connected to an external power source, so that there is no need for the operator to rotate and press manually.

[0036] The specific implementation method is as follows: During operation, the hydrogen storage cylinder is placed into the pressing unit 4. The transmission head of the motor 22 causes the circle piece four 6 to rotate through the circle block five 23. The circle piece four 6 causes the circle block four 21 to rotate. The circle block four 21 causes the circle cover five 8 to rotate. The circle cover five 8 causes the linkage lever 9 to move. The linkage lever 9 presses the pressing block 10 to squeeze against the hydrogen storage cylinder. The operator rotates the rotating piece 37 through the shifting block 38. The rotating piece 37 causes the outer cover 36 to rotate. The outer cover 36 causes the prism five 28 to rotate. The prism five 28 rotates through the connecting lever 27 to cause the connecting lever 27 to move. The prism five 28 moves inside the outer cover 36. The connecting lever 27 presses the plug 26 to shorten the length of the helical beryllium copper wire 25. The helical beryllium copper wire 25 presses the prism four 24 to tightly adhere to the hydrogen storage cylinder through the pressing block 10. Through the shortening degree of the helical beryllium copper wire 25, the squeezing strength borne by the hydrogen storage cylinder is identified, which is conducive to the operator to identify the pressing strength of the pressing block 10 according to the shortening degree of the prism five 28, and is conducive to the operator to control the pressing strength on the hydrogen storage cylinder to protect the hydrogen storage cylinder from being damaged by pressing.

[0037] During the stage when the length of the helical beryllium copper wire 25 shortens, the connecting block 32 extends into the connecting cover 31. Through the helical beryllium copper wire 25, it is conducive to reducing the amplitude of the prism four 24. Through the connecting block 32, the water-like medium becomes viscous, reducing the amplitude of the pressing block 10. During the stage when the pressing block 10 vibrates, it causes the connecting block 32 to move cyclically in the helically wound connecting cover 31, causing the helically wound connecting cover 31 to generate a medium that inhibits the movement of the connecting block 32, reducing the amplitude of the pressing block 10, weakening the vibration of the hydrogen storage cylinder during vehicle driving, and being conducive to maintaining the pressing strength of the pressing unit 4 on the hydrogen storage cylinder during the vibration stage of the hydrogen storage cylinder.

[0038] During the stage when the plug 26 presses the helical beryllium copper wire 25, the water-like medium in the linkage lever 9 is guided to the filling port 33 through the check valve in a water guide channel 35, causing the leather cover 34 to expand, expanding the pressing surface between the leather cover 34 and the hydrogen storage cylinder, improving the squeezing efficiency of the pressing block 10 on the hydrogen storage cylinder, and being conducive to the installation of the hydrogen storage cylinder. When the helical beryllium copper wire 25 returns to its original state, the water-like medium is guided back into the linkage lever 9 through the check valve in another water guide channel 35.

[0039] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed.
