[0022] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0023] Please refer to Figure 1 as well as Figure 2 A hydrogen refueling tank replacement structure for a vehicle includes a housing 1. The housing 1 includes a first chamber 11 and a second chamber 12, which are respectively located at both ends of the length of the housing 1. The first chamber 11 is provided with a hydraulic system 111, which is located at the end of the first chamber 11 away from the second chamber 12. The second chamber 12 is provided with a hydrogen fueling system 121, which is located at the end of the second chamber 12 away from the first chamber 11.

[0024] As can be seen from the above description, the beneficial effects of this utility model are as follows: by designing the housing 1 to include a first chamber 11 and a second chamber 12, and respectively providing a hydraulic system 111 and a hydrogen fuel system 121, a clear division of the internal functions of the system is achieved. This design not only effectively isolates the hydraulic system 111 and the hydrogen fuel system 121, thereby avoiding mutual interference, but also ensures the compactness and rationality of the vehicle's internal layout, making the arrangement of each system more in line with actual usage requirements. In addition, the hydraulic system 111 and the hydrogen fuel system 121 are both located at the far end of their respective chambers, which helps to reduce heat interference and improve the stability and safety of the system. Specifically, a partition is also provided around the hydrogen fuel cell to ensure that the hydrogen fuel cell will not drift towards the hydraulic station side after leakage. In some embodiments, the housing 1 also includes a support frame 13, which includes an intermediate support frame 131, through which the first chamber 11 and the second chamber 12 are separated. By adding the support frame 13 and dividing it into an intermediate support frame 131, the first chamber 11 and the second chamber 12 are stably separated. This structure not only enhances the overall stability of the housing 1, but also effectively improves the convenience of installation and disassembly. The design of the intermediate support frame 131 allows for better physical isolation between the chambers, helping to prevent cross-influence of heat between different systems and ensuring the efficient operation of the hydraulic system 111 and the hydrogen fuel system 121.

[0025] In some embodiments, the enclosure 1 further includes a first wall panel 14 and a second wall panel 15, both of which are detachably connected to the support frame 13. The first wall panel 14 is located on both sides of the support frame 13 along its length, and the second wall panel 15 is located on the upper part of the support frame 13. This design, by providing detachable first wall panels 14 and second wall panels 15 on both sides of the support frame 13, makes the maintenance and repair of the enclosure 1 more convenient. This detachable connection design makes the structure of the enclosure 1 more flexible, allowing for modular operation according to actual needs, facilitating future equipment replacement and maintenance. The wall panels also effectively protect the internal components of the enclosure 1, reducing the impact of the external environment on the internal equipment.

[0026] In some embodiments, the first wall panel 14, the second wall panel 15, and the support frame 13 at least partially enclose the first chamber 11 and the second chamber 12. The overall enclosed design of the first wall panel 14, the second wall panel 15, and the support frame 13 provides effective sealing and protection for the first chamber 11 and the second chamber 12. This design not only enhances the sealing performance of the housing 1 but also improves the stability of the system under high loads or extreme environments. The enclosed structure facilitates airflow and temperature control in each chamber, thereby ensuring that the hydraulic system 111 and the hydrogen fuel system 121 can fully perform under their respective operating conditions.

[0027] Specifically, the section of the second wall panel 15 located in the second chamber 12 is provided with heat dissipation holes 16. The design of providing heat dissipation holes 16 in the area of ​​the second wall panel 15 effectively improves the heat dissipation performance of the hydrogen fuel system 121. This arrangement of heat dissipation holes 16 helps the hydrogen fuel system 121 maintain a suitable temperature range in high-temperature operating environments, thereby avoiding performance degradation or malfunctions caused by system overheating. This structure effectively enhances the safety and stability of the hydrogen fuel system 121.

[0028] Specifically, the section of the first wall panel 14 located in the second chamber 12 is provided with heat dissipation holes 16. The design of providing heat dissipation holes 16 in the area of ​​the first wall panel 14 complements the design of heat dissipation holes 16 in the second wall panel 15, further improving the temperature management effect inside the enclosure 1. By rationally arranging the positions of the heat dissipation holes 16, the heat inside the enclosure 1 can be effectively dissipated to the outside quickly, avoiding heat accumulation and ensuring that all parts of the system operate within the normal operating temperature range.

[0029] In some embodiments, the first chamber 11 further includes a lubrication system 112, which is located at the end of the first chamber 11 away from the hydraulic system 111. The design of the first chamber 11 with the lubrication system 112 provides necessary lubrication to other mechanical components of the vehicle, reducing friction and improving their efficiency and service life. The location of the lubrication system 112 away from the hydraulic system 111 avoids direct impact of oil contamination on the hydraulic equipment, helping to ensure the long-term reliability of the hydraulic system 111.

[0030] In some embodiments, the second chamber 12 further includes a cooling system 122, which is located at the end of the second chamber 12 away from the hydrogen fuel system 121 and is connected to the hydraulic system 111 via a pipeline. The cooling system 122, located within the second chamber 12 and connected to the hydraulic system 111 via a pipeline, allows the coolant to effectively dissipate heat from the hydraulic system 111, thereby reducing equipment damage caused by high temperatures. The addition of the cooling system 122 significantly improves the system's high-temperature resistance, especially under high-load operation, effectively reducing the temperature rise of both the hydraulic system 111 and the hydrogen fuel system 121, extending their service life. Simultaneously, the cooling system 122 and the hydrogen fuel system 121 are both located in the second chamber 12, sharing the heat dissipation holes 16 of the second chamber 12 for centralized heat dissipation, resulting in a more rational structural design and avoiding the mixing of hot and cold temperatures in the working area.

[0031] In some embodiments, a hydrogen storage system 2 is also included. The hydrogen storage system 2 is located outside the housing 1, near the second chamber 12, and is connected to the hydrogen fuel system 121 via a pipeline. The design of placing the hydrogen storage system 2 outside the housing 1 and connecting it to the hydrogen fuel system 121 allows the vehicle's hydrogen fuel system 121 to have a larger hydrogen storage capacity and a longer driving range. Positioning the hydrogen storage system 2 near the second chamber 12 effectively reduces interference between systems, improving the safety and convenience of the hydrogen storage system 2. This rational layout also facilitates the replenishment and replacement of hydrogen.

[0032] In some embodiments, the hydrogen fuel system 121 is detachably connected to the second chamber 12. This detachable connection design allows for rapid replacement or maintenance of the hydrogen fuel system 121 as needed. This design significantly improves the system's flexibility and maintainability, ensuring timely replacement or repair of the hydrogen fuel system 121 when required, reducing downtime, and improving the overall vehicle's efficiency and stability. Furthermore, the detachable design of the hydrogen fuel system 121 allows its location to be repurposed for installing other equipment or battery modules to increase vehicle range.

[0033] In summary, this utility model provides a vehicle hydrogen refueling and tank-changing structure. Through a rationally designed tank structure for hydrogen fuel cell vehicles, it achieves effective isolation and efficient operation of the hydraulic system and the hydrogen fuel system. By setting up a first chamber and a second chamber, and configuring the hydraulic system and hydrogen fuel system in each chamber respectively, it not only avoids mutual interference between the systems but also improves the compactness and rationality of the vehicle's internal layout, thereby ensuring the vehicle's stability and safety. The support frame and detachable wall panel design make the tank structure more flexible, facilitating later maintenance and equipment replacement, while also improving the physical isolation effect of the system and preventing heat cross-contamination. In addition, the rational arrangement of heat dissipation holes and the configuration of the lubrication and cooling systems effectively improve the heat dissipation and temperature control capabilities of the hydraulic and hydrogen fuel systems, ensuring long-term stable operation of the system under high load conditions. The external arrangement of the hydrogen storage system and its connection with the hydrogen fuel system expands the hydrogen storage capacity, improves the driving range, and simplifies hydrogen replenishment and replacement operations. The detachable connection design between the hydrogen fuel system and the second chamber further enhances the system's flexibility and maintainability, allowing for quick replacement or upgrades as needed to meet different usage requirements.
