Description

Technical Field

[0001] This utility model relates to hydrogen fuel cell vehicle technology, specifically to an integrated support for a high-pressure hydrogen storage cylinder used in hydrogen fuel cell vehicles. Background Technology

[0002] With the rapid development of hydrogen fuel cell vehicles, the safe and stable installation of high-pressure hydrogen storage cylinders, as a key energy storage component of fuel cell systems, is particularly important. Traditional high-pressure hydrogen storage cylinder brackets mostly use bolt fastening, achieving compression and fixation through threaded connections from the side or sides of the hydrogen storage cylinder. However, within the extremely compact space of a car chassis frame, the space for installation and maintenance is severely limited, making it inconvenient to tighten or disassemble using tools such as wrenches.

[0003] Based on this, the present invention provides an integrated support for high-pressure hydrogen storage cylinders for hydrogen fuel cell vehicles. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides an integrated bracket for high-pressure hydrogen storage cylinders in hydrogen fuel cell vehicles. This allows workers to easily install or remove hydrogen storage cylinders within a confined space. Within the vehicle's frame, the hydrogen storage cylinders can be installed or removed without tools; simply tightening and loosening the threaded sleeves by hand eliminates the hassle of finding, using, and storing specialized tools.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated support for a high-pressure hydrogen storage cylinder for hydrogen fuel cell vehicles, comprising a base, a frame on the top of the base; multiple placement pads, all disposed on the top of the base, for placing the hydrogen storage cylinder; an arc-shaped sleeve disposed on the hydrogen storage cylinder; a connecting post disposed on the top of the base, with the side end of the arc-shaped sleeve contacting the top end of the connecting post; and a pair of locking members symmetrically disposed on the top of the base, for pressing the side end of the arc-shaped sleeve against the top end of the connecting post.

[0006] Furthermore, the locking component includes a column disposed on the top of the base; a threaded rod disposed on the top of the column; a pressure bar passing through the middle of the threaded rod, the bottom of the pressure bar contacting the top of the arc-shaped sleeve; a threaded sleeve threaded on the top of the threaded rod, the bottom of the threaded sleeve contacting the top of the pressure bar; and a return spring passing through the middle of the threaded rod for extending and returning the pressure bar to its original position.

[0007] Furthermore, the side end of the arc-shaped sleeve is provided with a groove, and the bottom end of the pressure strip is provided with a convex pad, which is disposed in the groove.

[0008] Furthermore, a movable disc is provided at the top of the connecting column via an elastic element, and the movable disc contacts the arc-shaped retaining sleeve.

[0009] Furthermore, a retaining pad is provided on the top of the base, and the side end of the hydrogen storage cylinder is inserted into the retaining pad.

[0010] Furthermore, the frame is internally rotatably provided with a rotating shaft, the middle of which is provided with an eccentric disk. The side of the eccentric disk is in contact with the hydrogen storage bottle. A crossbar is provided at the side end of the rotating shaft, and a sleeve is slidably provided on the side of the frame. The sleeve can be inserted and connected to the crossbar.

[0011] Compared with the prior art, the present invention provides an integrated support for high-pressure hydrogen storage cylinders for hydrogen fuel cell vehicles. The hydrogen storage cylinder is placed on a placement pad, and then an arc-shaped sleeve is placed on the hydrogen storage cylinder, ensuring that both ends of the arc-shaped sleeve contact the corresponding connecting post. Then, the top of the arc-shaped sleeve is pressed and contacted by a locking member, thereby completing the compression and fixation of the hydrogen storage cylinder. This structural design makes it convenient for workers to install or remove the hydrogen storage cylinder in a narrow frame space.

[0012] By rotating the threaded sleeve, the threaded sleeve is moved away from the pressure bar, thus separating the pressure bar from the arc-shaped retainer. Then, the compressed return spring extends, lifting the pressure bar, and the arc-shaped retainer can be removed. When installing the arc-shaped retainer, the side end of the arc-shaped retainer contacts the connecting post. Then, the pressure bar is placed on top of the arc-shaped retainer, and the threaded sleeve is rotated so that the bottom end of the threaded sleeve presses against the pressure bar, thus completing the fixation of the arc-shaped retainer. Through this structural design, the hydrogen storage tank can be disassembled or installed within the car body space without the use of tools. Locking and releasing can be achieved by simply turning the threaded sleeve by hand, eliminating the trouble of finding, using, and storing special tools. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] As attached Figure 1 To be continued Figure 6 As shown:

[0024] Example 1:

[0025] This utility model provides an integrated support for a high-pressure hydrogen storage cylinder for hydrogen fuel cell vehicles, including a base 1, multiple placement pads 3, an arc-shaped sleeve 5, a connecting post 6, and a pair of locking components 7.

[0026] The base 1 has a frame 2 on its top; multiple placement pads 3 are placed on the top of the base 1 for placing hydrogen storage cylinders 4; an arc-shaped sleeve 5 is placed on the hydrogen storage cylinder 4; a connecting post 6 is placed on the top of the base 1, and the side end of the arc-shaped sleeve 5 contacts the top end of the connecting post 6. There are two connecting posts 6, which are arranged sequentially on the top of the base 1 and correspond to the side ends of the arc-shaped sleeve 5; a pair of locking parts 7 are symmetrically arranged on the top of the base 1 to make the side ends of the arc-shaped sleeve 5 press against the top end of the connecting post 6; the top of the base 1 has multiple threaded holes for mounting the base 1 on a car.

[0027] Specifically, the hydrogen storage cylinder 4 is placed on the placement pad 3, and then the arc-shaped sleeve 5 is placed on the hydrogen storage cylinder 4, ensuring that both ends of the arc-shaped sleeve 5 are in contact with the corresponding connecting post 6. Then, the top of the arc-shaped sleeve 5 is pressed and contacted by the locking member 7, thereby completing the compression and fixing of the hydrogen storage cylinder 4. This structural design makes it convenient for workers to install or remove the hydrogen storage cylinder 4 in a narrow frame space.

[0028] like Figures 2 to 6 As shown, the locking component 7 includes a column 700, a threaded rod 701, a pressure bar 702, a threaded sleeve 703, and a return spring 704. The column 700 is located on the top of the base 1. The threaded rod 701 is located at the top of the column 700. The pressure bar 702 passes through the middle of the threaded rod 701, and the bottom of the pressure bar 702 contacts the top of the arc-shaped sleeve 5. The threaded sleeve 703 is threaded onto the top of the threaded rod 701, and the bottom of the threaded sleeve 703 contacts the top of the pressure bar 702. The return spring 704 passes through the middle of the threaded rod 701 and is used for the extension and return of the pressure bar 702. The threaded sleeve 703 is a lock nut.

[0029] Specifically, by rotating the threaded sleeve 703, the threaded sleeve 703 is moved away from the pressure bar 702, thereby separating the pressure bar 702 from the arc-shaped retaining sleeve 5. Then, the compressed return spring 704 extends, thereby lifting the pressure bar 702, and then the arc-shaped retaining sleeve 5 can be removed. When installing the arc-shaped retaining sleeve 5, the side end of the arc-shaped retaining sleeve 5 contacts the connecting post 6. Then, the pressure bar 702 is placed on the top of the arc-shaped retaining sleeve 5, and then the threaded sleeve 703 is rotated, so that the bottom end of the threaded sleeve 703 presses against the pressure bar 702, thereby completing the fixation of the arc-shaped retaining sleeve 5. Through this structural design, the hydrogen storage cylinder 4 can be disassembled or installed in the car body space without the use of tools. Locking and releasing can be achieved by simply turning the threaded sleeve 703 by hand, saving the trouble of finding, using and storing special tools.

[0030] like Figure 6 As shown, the side end of the arc-shaped sleeve 5 is provided with a groove, and the bottom end of the pressure strip 702 is provided with a convex pad 705. The convex pad 705 is disposed in the groove. When the pressure strip 702 contacts the arc-shaped sleeve 5, the convex pad 705 at the bottom of the pressure strip 702 can be inserted into the groove, thereby increasing the stability of the contact between the pressure strip 702 and the arc-shaped sleeve 5.

[0031] like Figure 6 As shown, the top of the connecting column 6 is provided with a movable disc 8 through an elastic element. The movable disc 8 contacts the arc-shaped sleeve 5. The elastic element can be a spring or a spring telescopic rod. With this design, when the arc-shaped sleeve 5 is disassembled, the movable disc 8 can move upward, thereby pushing the arc-shaped sleeve 5 to separate from the hydrogen storage bottle 4.

[0032] like Figure 1As shown, a retaining pad 9 is provided on the top of the base 1, and the side end of the hydrogen storage bottle 4 is inserted into the retaining pad 9. This design can ensure the stability of the hydrogen storage bottle 4 when it moves back and forth.

[0033] Example 2:

[0034] This embodiment is a further optimization based on the first embodiment described above. The parts that are the same as those in the aforementioned technical solution will not be repeated here. Figure 2 As shown, in order to better realize this utility model, the following arrangement is adopted. In this embodiment, a rotating shaft 10 is rotatably arranged inside the frame 2, an eccentric disk 11 is arranged in the middle of the rotating shaft 10, the side of the eccentric disk 11 is in contact with the hydrogen storage bottle 4, a crossbar 12 is arranged at the side end of the rotating shaft 10, and a plug sleeve 13 is slidably arranged on the side of the frame 2, which can be plugged into the crossbar 12.

[0035] Specifically, the crossbar 12 can be rotated to make the shaft 10 rotate, thereby causing the eccentric disk 11 to press against the side of the hydrogen storage bottle 4 and cooperate with the pad 9 to complete the stable connection of the hydrogen storage bottle 4. Finally, by pushing the insert 13, the insert 13 is inserted into the crossbar 12 to complete the limitation of the crossbar 12.

[0036] This structural design adds active clamping and mechanical self-locking in the horizontal direction to the vertical clamping, thus creating a stable and safe fixed support.

[0037] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The machinery, parts and equipment adopt conventional models in the existing technology, which will not be described in detail here.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
