[0033] Example one

[0034] Please refer to Figure 1 , Figure 2 and Figure 3 , the present embodiment provides a kind of cabin door structure of hydrogen bottle cover, including door frame 10, door body 20 and door lock 30, door frame 10 is set on hydrogen bottle cover and forms the opening 101 for placing or taking out hydrogen bottle;Door body 20 is provided with the gas-permeable part 201 greater than the board face half area of door body 20, door body 20 is hingedly arranged on door frame 10, for opening or closing the opening 101;Door lock 30 includes the latch part 301 on the inner side of door body 20 and the lock groove part 302 on door frame 10.

[0035] Specifically, the door frame 10 and the door body 20 can be made of sheet metal material to ensure structural strength, and the surface can be coated to improve corrosion resistance. In addition, the air permeable part 201 of the door body 20 is designed to be detachable, so that different air permeable plates with different pore sizes can be replaced in different use environments to adapt to different ventilation needs.

[0036] The design of the large-area air permeable part 201 on the door body 20 in this embodiment 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.

[0037] The door lock 30 in this embodiment is locked by the cooperation of the latch part 301 and the lock groove part 302. For example, the type of the door lock 30 can be a buckle type, a rotary type, or an electronic control lock, etc. to ensure that a stable closing force can be provided under various operating conditions to prevent accidental opening. In addition, the structure of the door lock 30 can cope with vibration or impact, and the door lock 30 can remain in the locked state to ensure the safety of the hydrogen cylinder.

[0038] Further, as shown in Figure 2 , the latch part 301 in this embodiment includes a lock head 3011 that locks or separates with the lock groove part 302, a pull rod 3012 connected with the lock head 3011, and a handle 3013 that drives the pull rod 3012 to move. The lock head 3011 and the pull rod 3012 are arranged on the inner side of the door body 20, and the handle 3013 penetrates the door body 20. The lock groove part 302 can be arranged at the top of the door frame, and the lock head 3011 is located directly below the lock groove part 302. The lock head 3011 and the lock groove part 302 are locked or unlocked by cooperation, and the door body 20 is locked or unlocked.

[0039] In use, the handle 3013 is pulled to drive the pull rod 3012 and the lock head 3011 to move downward, so that the lock head 3011 separates from the lock groove, and the door body 20 is immediately opened. When the door body 20 is closed, the handle 3013 pushes the lock head 3011 upward into the lock groove, and the lock head 3011 is locked with the lock groove part 302 to ensure that the door body 20 is securely locked.

[0040] As shown in Figure 2 , the hinge between the door body 20 and the door frame 10 in this embodiment is a limiting block hinge 40, which can limit the opening angle of the door body 20. One of the main functions of the limiting block in the structure of the limiting block hinge 40 is to limit the movement range of mechanical parts to prevent them from exceeding the predetermined stroke. In this way, the door body 20 can be stably opened or closed within a certain angle range to avoid damage caused by excessive opening or closing. At the same time, the design of the limiting block can also prevent the door body 20 from exceeding the safety range due to inertia or other external forces during opening, thereby ensuring safety during use.

[0041] As shown in Figure 3 and Figure 4 In this embodiment, the air permeable part 201 is a mesh structure, which can be a hexagonal honeycomb design. This structure not only reduces weight while maintaining material strength, but also effectively improves air permeability. Each unit of the hexagon is connected to each other, forming a stable frame structure that maintains structural integrity and function even under high pressure, with good structural stability.

[0042] As shown in Figure 3 In this embodiment, the air permeable part 201 is arranged at the middle position of the door body 20, so that the edge of the door body 20 is the structure of the plate body 203, improving the structural strength of the edge of the door body 20, so as to improve the convenience of actual operation and the stability of the structure of the door body 20.

[0043] As shown in Figure 2 and Figure 3 In this embodiment, the door body 20 includes a support frame 202, a plate body 203 arranged on the support frame 202, and an air permeable mesh 204 arranged between the plate body 203 and the support frame 202. The plate body 203 is provided with a through hole 2031 exposing the air permeable mesh 204. Through the design of the support frame 202, the rigidity and strength of the door body 20 can be improved, and the setting of the air permeable mesh 204 enhances the heat dissipation effect of the whole door body 20, ensuring that the hydrogen cylinder can maintain a suitable temperature after long-time operation, prolonging the service life. The structural design of the air permeable mesh 204 can also effectively reduce the wind resistance and reduce the noise that may be generated during high-speed driving, improving the comfort of the passengers.

[0044] Further, in this embodiment, the air permeable mesh 204 is integrally formed with the plate body 203, which can improve the structural strength of the plate body 203, reduce the steps of production or installation, and at the same time, on the surface of the hydrogen cylinder door, a special coating treatment can be used, such as anti-rust or weather-resistant coating, to improve its durability and reliability in harsh environments, and to ensure the long-term safe storage of the hydrogen cylinder.
