As to the two sides of the arched shell, the driver's cabin and the carriage of the vehicle can be connected and shielded. Alternatively, a partition is mounted to cover the frame structure 102 as a whole, thereby further enhancing the stability of the overall structure and the aesthetic appearance.

[0041] Further, the air-permeable mesh 2021 of the door structure 20 is designed to effectively improve the ventilation performance, ensure the airflow circulation in the interior of the frame body 10, reduce the internal temperature, and further enhance the safety during use. Meanwhile, the air-permeable mesh 2021 can be arranged in the middle of the door plate 202 of the door structure 20 and can be designed in a large area to improve the air-permeable effect, ensure good heat dissipation of the hydrogen cylinder during use, and reduce safety hazards. In addition, the layout of the door structure 20 is optimized to ensure the ventilation effect and avoid the entry of foreign matters, further improving the use safety.

[0042] As shown in Figure 1 and Figure 2 , the fixed part 101 in the embodiment includes the first support beam 1011 and the second support beam 1012 arranged symmetrically, and a plurality of locking plates 1013 are arranged on the first support beam 1011 and the second support beam 1012 to be fixedly connected with the main beam of the vehicle; a plurality of first support rods 1014 are further arranged on the first support beam 1011 to form a triangular support with the bottom of the frame body 10, and a plurality of second support rods 1015 are further arranged on the second support beam 1012 to form a triangular support with the bottom of the frame body 10.

[0043] In terms of structure, the bottom is supported by the support beam, and then a triangular support system is formed by the support rods to enhance the stability of the whole. Then, the locking plates 1013 are tightly connected with the main beam of the vehicle, such as welding or bolt connection, to ensure the firm combination of the protective cover structure and the vehicle. In addition, the design of the support beam and the support rod not only improves the carrying capacity, but also optimizes the stress distribution, so that the hydrogen cylinder protective cover structure is stably installed on the beam frame of the vehicle.

[0044] And the design of the first support rod 1014 and the second support rod 1015 not only disperses the pressure, but also improves the impact resistance, so that the hydrogen cylinder is still stably installed on the frame structure 102 under complex road conditions, improving the stability and safety of the structure.

The second mounting plate 1022 is provided with a plurality of second mounting holes 1027 arranged face-to-face with the first mounting holes 1026. The design of the first mounting holes 1026 and the second mounting holes 1027 can realize the fixing mode of the two-end sleeve connection, and then ensure the stable installation of the mounting plate and the hydrogen cylinder through bolt locking.

[0048] Then, a space can be arranged between the frame structure 102 and the door structure 20 for personnel to operate. The space is designed reasonably for personnel to operate, which is convenient for daily maintenance and inspection and ensures the safety of the operating personnel, further improving the convenience and reliability of the hydrogen cylinder use. Through the optimization of the space layout, the operating personnel can easily install and disassemble the hydrogen cylinder, reducing the maintenance difficulty.

In addition, the air permeable mesh 2021 of the door body can be designed to be detachable, so that different pore size air permeable plates can be replaced in different use environments to adapt to different ventilation needs. The design of the large-area air permeable mesh 2021 on the door plate 202 can ensure the air permeability of the hydrogen cylinder position and reduce the risk of hydrogen cylinder overheating caused by high temperature or high humidity environment to a certain extent, thereby improving the safety and service life of the hydrogen cylinder.

[0051] The door lock 2022 in the embodiment is locked by the cooperation of the latch part and the bolt 2031, for example, the type of the door lock 2022 can be a buckle type, a rotary type or an electronic control lock, etc., to ensure that stable closing force can be provided under various operating conditions to prevent accidental opening. In addition, the door lock 2022 is designed to withstand vibration or impact, and the door lock 2022 can remain locked to ensure the safety of the hydrogen cylinder.

The limiting hinge part 204 can limit the opening angle of the door plate 202. One of the main functions of the limiting block in the limiting block hinge structure is to limit the movement range of the mechanical part to prevent it from exceeding the predetermined stroke. In this way, it is ensured that the door plate 202 is stably opened or closed within a certain angle range, avoiding damage due to excessive opening or closing. At the same time, the design of the limiting block can also prevent the door plate 202 from exceeding the safety range due to inertia or other external forces during opening, thereby ensuring safety during use.

[0053] As shown in Figure 5 In the embodiment, a connecting block 1025 is arranged on the side frame adjacent to the first mounting plate 1021 of the frame structure 102. The connecting block 1025 can be fixed on the frame structure 102 by locking or welding, and a plurality of positioning holes can be arranged on the connecting block 1025 to facilitate locking connection with other structures; or the connecting block 1025 is connected by welding, and the welding point is provided by the connecting block 1025 to ensure firm and reliable connection.
