In heavy-duty trucks and tractor units, the hydrogen storage cylinders are often arranged in a multi-layered stacked configuration. During mass production, to improve space utilization and meet lightweight requirements, the overall vehicle design often integrates some vehicle components such as batteries, DC-DC converters, and multi-function controllers onto the hydrogen system frame.

[0003] However, due to the small gaps between the frame and the components, installation difficulties often occur during actual installation, increasing the labor intensity of operators and making them more susceptible to injury.

[0004] Therefore, how to provide a framework system for on-board hydrogen systems has become a technical challenge that urgently needs to be solved in this field. Utility Model Content

[0025] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0026] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0027] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0028] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0029] like Figures 1 to 4 As shown, this embodiment of the present invention provides a frame system for an on-board hydrogen system, including: a hydrogen system frame 1, a fixing bracket 2, and a guide rail device 3; the hydrogen system frame 1 is mounted on the guide rail device 3. Specifically, multiple key components are installed on the hydrogen system frame 1, including a hydrogen source system, a fuel cell stack, a control system, a thermal management system, and an auxiliary system. These components work together to ensure the normal operation and efficient functioning of the hydrogen fuel cell system. The specific arrangement is not limited here.

[0030] The fixed bracket 2 is slidably mounted on the guide rail device 3. The fixed bracket 2 includes a fixed frame 21 and a fixed component 23. The bottom of the fixed frame 21 is provided with a pulley 22, and the fixed component 23 is mounted on the fixed frame 21 to form multiple mounting parts for mounting the component 4.

[0031] Specifically, the fixed bracket 2 is located between the hydrogen system frame 1 and the guide rail device 3. The mounting part is located above the fixed frame 21.

[0032] The guide rail device 3 includes a support bracket 31, a slide rail 32, and a limiting component 34. The support bracket 31 is located at the bottom of the hydrogen system frame 1. The slide rail 32 is disposed in the support bracket 31, and the pulley 22 is slidably disposed with the slide rail 32. The limiting component 34 is disposed on the slide rail 32 and is used to limit the pulley 22 and the fixed frame 21.

[0033] Specifically, during assembly, the operator first installs the vehicle component 4 onto the mounting section. Then, the pulley 22 at the bottom of the fixing frame 21 is placed on the slide rail 32, and the fixing frame 21 is moved to the end of the support bracket 31 under the action of the pulley 22. At this time, the fixing frame 21 and the pulley 22 are fixed to the support bracket 31 under the limiting action of the limiting component 34, thereby completing the installation of component 4.

[0034] This invention forms multiple mounting portions for installing components 4 by providing pulleys 22 at the bottom of a fixed frame 21 and mounting a fixing component 23 on the fixed frame 21; a support bracket 31 is located at the bottom of the hydrogen system frame 1, a slide rail 32 is installed in the support bracket 31, and the pulleys 22 slide alongside the slide rail 32; a limiting component 34 is installed on the slide rail 32. During assembly, the operator first installs the vehicle components 4 onto the mounting portions, then places the pulleys 22 at the bottom of the fixed frame 21 onto the slide rail 32, and moves the fixed frame 21 to the end of the support bracket 31 under the action of the pulleys 22. At this time, the fixed frame 21 and the pulleys 22 are fixed to the support bracket 31 under the limiting action of the limiting component 34, thereby completing the installation of components 4. This solves the current problem of difficult installation of components 4, effectively reduces the labor intensity of operators, and provides protection for the personal safety of operators.

[0035] In one embodiment of the frame system for an on-board hydrogen system of this utility model, such as Figures 1 to 4 As shown, the bottom of the slide rail 32 is provided with an opening 33, which is located at both ends of the slide rail 32.

[0036] The limiting assembly 34 includes two first connecting plates 341, two second connecting plates 342, a first limiting plate 343, and a second limiting plate 344. The two first connecting plates 341 and the two second connecting plates 342 are respectively spaced on both sides of the opening 33 and connected to the bottom of the slide rail 32. The two sides of the first limiting plate 343 and the second limiting plate 344 are respectively connected to the first connecting plate 341 and the second connecting plate 342. The included angle between the first limiting plate 343 and the second limiting plate 344 and the bottom of the slide rail 32 is the same, and the junction of the first limiting plate 343 and the second limiting plate 344 is the lowest point.

[0037] Specifically, the length of the opening 33 is greater than the length of the pulley 22, and the angle between the first limiting plate 343 and the second limiting plate 344 and the bottom of the slide rail 32 is an acute angle.

[0038] The first connecting plate 341, the second connecting plate 342, the first limiting plate 343, and the second limiting plate 344 form a downwardly recessed groove structure. When the pulley 22 moves to the opening 33, the pulley 22 will fall into the opening 33. At this time, the first limiting plate 343 and the second limiting plate 344 provide support for the pulley 22. Since the first limiting plate 343 and the second limiting plate 344 have an angle with the bottom of the slide rail 32, they limit the movement of the pulley 22, thereby avoiding the problem of the pulley 22 moving arbitrarily on the slide rail 32.

[0039] In one embodiment of the frame system for an on-board hydrogen system of this utility model, the first end of the first limiting plate 343 and the first end of the second limiting plate 344 are respectively horizontally arranged with the two ends of the opening 33. The first limiting plate 343 and the second limiting plate 344 are inclined downward toward the support bracket 31, and there is a gap between the second end of the first limiting plate 343 and the second end of the second limiting plate 344.

[0040] This utility model further enhances the limiting effect on the pulley 22 by tilting the first limiting plate 343 and the second limiting plate 344 towards the lower part of the support bracket 31 and setting a gap between the second end of the first limiting plate 343 and the second end of the second limiting plate 344.

[0041] In one embodiment of the frame system for an on-board hydrogen system of this utility model, such as Figures 1 to 4 As shown, the limiting component 34 also includes a first limiting hole 345 and a fixing block 346. The first limiting hole 345 is located on both sides of the first end of the support bracket 31, and the fixing block 346 is provided on both sides of the first end of the fixing frame 21. The fixing block 346 is provided with mounting holes corresponding to the first limiting hole 345. By installing the first fastening bolts on the mounting holes and the first limiting hole 345, the fixing bracket 2 is fixed on the support bracket 31.

[0042] This utility model uses a first limiting hole 345 located on both sides of the first end of the support bracket 31, and a mounting hole corresponding to the first limiting hole 345 is provided on the fixing block 346. By installing the first fastening bolt on the mounting hole and the first limiting hole 345, the fixing bracket 2 is fixed on the support bracket 31, thereby ensuring the stability of the connection between the support bracket 31 and the fixing bracket 2.

[0043] In one embodiment of the frame system for an on-board hydrogen system of this utility model, such as Figures 1 to 4As shown, the limiting component 34 also includes a second limiting hole 347 and a third limiting hole 348. The second limiting hole 347 is located on both sides of the second end of the support bracket 31, and the third limiting hole 348 is provided at the second end of the fixed frame 21 and corresponds to the second limiting hole 347. By installing second fastening bolts on the third limiting hole 348 and the second limiting hole 347, the fixed bracket 2 is fixed on the support bracket 31.

[0044] This invention provides a guarantee for fixing the fixed bracket 2 to the support bracket 31 by setting the second limiting hole 347 on both sides of the second end of the support bracket 31 and setting the third limiting hole 348 on the second end of the fixed frame 21, corresponding to the second limiting hole 347. By installing the second fastening bolt on the third limiting hole 348 and the second limiting hole 347, the fixed bracket 2 is fixed on the support bracket 31, which effectively improves the safety and stability of the frame system of this invention for vehicle hydrogen system during use.

[0045] In one embodiment of the frame system for an on-board hydrogen system of this utility model, such as Figures 1 to 4 As shown, the guide rail device 3 also includes two fixing plates 349, which are located at both ends of the support bracket 31, and the length direction of the fixing plates 349 is perpendicular to the length direction of the support bracket 31. The fixing plates 349 are set at the bottom of the support bracket 31.

[0046] In this utility model, two fixing plates 349 are respectively located at both ends of the support bracket 31, and the length direction of the fixing plates 349 is perpendicular to the length direction of the support bracket 31. The fixing plates 349 are set at the bottom of the support bracket 31.

[0048] Specifically, component 4 is mounted on two first fixing rods 231, two fixing rods 232, and two third fixing rods 233, thereby improving the stability of component 4 during installation.
