[0038] As Figures 1 to 3 shown, an embodiment of the first aspect of this application provides a fuel cell system chassis, including a box body 11 and a support portion 12. An accommodation cavity suitable for accommodating a fuel cell assembly is formed inside the box body 11; the support portion 12 is arranged at the bottom of the box body 11, and the support portion 12 is suitable for abutting against the ground to prevent the box body 11 from tipping over.

[0039] Generally, the total weight of the fuel cell system is about 4 tons, the width is 1.1 meters, the height is 2.3 meters, the length is 3.5 meters, and the center of gravity is at a position of about 0.7 meters. Specifically, the fuel cell assembly in the fuel cell system includes a fuel cell stack, a hydrogen storage device, an air supply device, a water / heat management system, a control system, a power converter, an energy storage device, etc. These components are all installed in the accommodation cavity of the box body 11.

[0040] The box body 11 has good corrosion resistance, sufficient strength and stiffness, and good insulation properties. The material can include stainless steel, cast aluminum alloy, polycarbonate, etc.

[0041] According to the fuel cell system chassis provided by the first aspect of the present application, the box body 11 is the main outer shell structure of the fuel cell system. There is a dedicated space inside the box body 11 to accommodate the fuel cell components, which can protect the internal fuel cell components from the external environment. Further, the support portion 12 is provided at the bottom of the box body 11 and can contact the ground, which can significantly increase the contact area between the chassis and the ground and form a stable fulcrum at the contact part with the ground, increasing the stability and anti-tipping ability of the system. Even under adverse conditions, the fuel cell system can remain upright and avoid the safety hazards caused by tipping. In summary, the fuel cell system chassis provided by the first aspect of the present application has anti-tipping performance and can improve the stability and safety of the fuel cell system.

[0042] As Figures 1 to 2 shown, in some embodiments of the present application, the support portion 12 is slidably embedded in the bottom of the box body 11; the support portion 12 includes a contracted state embedded in the bottom of the box body 11 and an extended state exposed outside the bottom of the box body 11; in the extended state, the support portion 12 abuts against the ground. The support portion 12 can be slidably embedded along the track or groove at the bottom of the box body 11, that is, the support portion 12 can move relative to the box body 11, so as to extend or retract when needed. During transportation or when additional support is not required, the support portion 12 is in a contracted state and is completely embedded in the bottom of the box body 11, which can reduce the floor area of the entire fuel cell system, facilitate handling and storage, and at the same time avoid damage or obstruction caused by the exposure of the support portion 12 during transportation. When the fuel cell system reaches the installation site and is ready to be positioned, the support portion 12 can be in an extended state. At this time, the support portion 12 will be exposed outside the bottom of the box body 11, contact the ground, increase the contact area between the box body 11 and the ground, increase the friction force, and form a stable fulcrum, thereby providing additional stability and support force to prevent the box body 11 system from tipping due to factors such as strong wind, earthquake, or unstable foundation. The telescopic direction of the support portion 12 can be horizontal or inclined towards the ground. No matter which direction is adopted, as long as it is ensured that the support portion 12 contacts the ground in the extended state.

[0043] As Figure 1 and Figure 3 shown, in some embodiments of the present application, a sliding groove 121 is formed on the support portion 12, and a guiding member matching the sliding groove 121 is provided on the box body 11. The matching of the sliding groove 121 and the guiding member enables the support portion 12 to slide smoothly along a predetermined path. Whether retracting from the bottom of the box body 11 or extending outwards, it can ensure smooth movement and avoid jamming or wear. The design of the sliding groove 121 and the guiding member increases the connection strength between the support portion 12 and the box body 11, ensuring that when the support portion 12 bears external forces, such as strong wind or vibration, the entire structure can remain stable and reduce the safety hazards caused by mechanical loosening or deformation.

[0044] Furthermore, the guiding member can be a T-shaped guiding strip or a roller, etc. The T-shaped guiding strip can provide better lateral stability and prevent the support portion 12 from laterally offsetting during movement. The roller contacts the support portion 12 and rolls along the sliding groove 121, which can reduce friction and ensure the smooth movement of the support portion 12.

[0045] In some embodiments of the present application, a locking member is provided at the bottom of the box body 11; when the support portion 12 is in the extended state, the locking member is adapted to abut against the support portion 12. When the support portion 12 extends from the bottom of the box body 11 to the extended state, the function of the locking member is to abut against the support portion 12 and fix it in place, preventing the support portion 12 from accidentally retracting due to external forces (such as wind force, vibration or human error). This can ensure that the support portion 12 continuously provides stable support during the operation of the entire system.

[0046] Furthermore, the specific design of the locking member can be in various forms. Specifically:

[0047] In some embodiments of the present application, the locking member includes a fastening bolt, and a threaded hole is formed on the support portion 12. By rotating the fastening bolt into the threaded hole and gradually applying a fastening force, the support portion 12 is locked in the current extended position.

[0048] In some other embodiments of the present application, the locking member can be a buckle or a pawl. Using the buckle or pawl structure, it can be automatically locked when the support portion 12 reaches the designated position, providing a fast and reliable fixing method.

[0049] In some other embodiments of the present application, the locking member can also be a hydraulic or pneumatic lock. In high-end or highly automated systems, hydraulic or pneumatic locking members can be used to automatically lock the support portion 12 through a pressure system, providing a higher level of stability and control.

[0050] Such as Figure 3As shown, in some embodiments of the present application, a limiting plate 122 is provided at the tail end of the support portion 12; when the support portion 12 is in the extended state, the limiting plate 122 abuts against the bottom of the box body 11. The tail end refers to the end of the support portion 12 facing the box body 11. When the support portion 12 slides outwards to its extended state, the limiting plate 122 will contact the bottom of the box body 11, preventing the support portion 12 from further moving. This can ensure that the support portion 12 reaches a consistent and preset extended position each time it extends, so as to provide the required stability and support force. The abutting effect of the limiting plate 122 in the extended state also helps to enhance the connection stability between the support portion 12 and the box body 11, preventing the support portion 12 from shaking or shifting when subjected to external forces (such as wind or ground vibration), thereby improving the stability of the entire system. The setting of the limiting plate 122 can prevent the support portion 12 from overextending and avoid mechanical damage (such as deformation or fracture) caused by exceeding the design limit, thus extending the service life of the support portion 12.

[0051] In some embodiments of the present application, in the extended state, the exposed length of the support portion 12 is at least 25 centimeters. The minimum exposed length of 25 centimeters can ensure sufficient stability and support area when the support portion 12 is in use, especially on uneven or soft ground. The longer support portion 12 can better disperse the weight applied by the upper structure, reduce the pressure on the ground, and thus bear a greater weight.

[0052] As Figure 1 and Figure 3 As shown, in some embodiments of the present application, a fixing hole 123 suitable for installing a fixing member is formed at the head end of the support portion 12; a pulling hole 124 is also formed at the head end of the support portion 12. The head end refers to the end of the support portion 12 that can be exposed in the extended state, and this end can contact the ground or be connected to a certain component on the ground in the extended or use state.

[0053] The fixing hole 123 is designed for installing fixing members (such as expansion bolts, pins or quick-release buckles), so that the support portion 12 can be firmly connected to the ground or ground components, enabling the support portion 12 to be stably attached to an appropriate position on the ground, and at the same time facilitating disassembly and maintenance.

[0054] The pulling hole 124 is for the convenience of the operator when extending or contracting the support portion 12. For example, the operator can hook a finger into the pulling hole 124 to pull the support portion 12 to extend it to the required length.

[0055] Furthermore, the pulling hole 124 can also be used to connect ropes, pull rings or other auxiliary tools to more easily control the movement of the support portion 12.

[0056] As Figures 1 to 3As shown, in some embodiments of the present application, the support portion 12 is a plate-like structure, and the support portion 12 is provided on the front and back of the bottom of the box body 11. The plate-like structure provides a large contact area when contacting the ground, which helps to disperse the weight of the box body 11, thereby improving the overall stability, especially on soft or uneven ground. The plate-like structure can be compactly retracted when not in use, reducing the space occupied and facilitating the transportation and storage of the equipment. The plate-like structure is convenient for manual or mechanical telescopic operation. At the same time, the plate-like design is also easy to cooperate with the guiding members at the bottom of the box body 11 to achieve smooth telescopic movement. In addition, the plate-like structure is relatively simple and easy to manufacture. It can be made by various processes such as stamping, cutting, and welding, which helps to control the manufacturing cost.

[0057] By arranging the support portion 12 on the front and back of the bottom of the box body 11, the symmetrically distributed support portions 12 on the front and back can provide uniform support force, which helps to maintain the balance and stability of the box body 11. At the same time, this layout expands the contact range between the support portion 12 and the ground, and solid support points can be found even on irregular ground.

[0058] As Figures 1 to 2 shown, further, in the embodiments of the present application, two support portions 12 are provided on each of the front and back. Multiple support portions 12 can allow the box body 11 to be finely adjusted under different terrain conditions to adapt to the undulations of the ground and ensure the stability of the box body 11 in various environments.

[0059] An embodiment of the second aspect of the present application provides a fuel cell system, including a fuel cell assembly and the fuel cell system chassis in any of the embodiments of the first aspect above; the fuel cell assembly is placed in the accommodation cavity of the box body 11.

[0060] According to the fuel cell system provided by the embodiment of the second aspect of the present application, the fuel cell assembly is placed in the accommodation cavity of the box body 11, which ensures that the assembly is fully protected from the external environment and is also convenient for the maintenance and replacement of the assembly. By combining the fuel cell assembly with an anti-tipping chassis, the entire system can operate safely and stably under outdoor conditions. Even in harsh environments such as strong winds or unstable foundations, it can maintain the integrity and functionality of its structure, enhancing the stability and safety of the fuel cell system.

[0061] What is not described in the present application can be achieved by adopting or referring to the existing technologies.

[0062] Each embodiment in this specification is described in a progressive manner. The same or similar parts among the embodiments can be referred to each other, and the key points of each embodiment are the differences from other embodiments.

[0063] The above are only embodiments of the present application and are not intended to limit the present application.
