[0100] Optionally, as shown in Figures 3 and 4, the first plate 31 of the cabinet door 30 is connected to a third plate 33 on the side close to the top plate 12, and there is an angle between the third plate 33 and the first plate 31. For rainwater that drifts in from between the first plate 31 and the top plate 12, the third plate 33 can play a certain shielding role, preventing impurities such as rainwater from entering the cabinet body 10, thereby improving the sealing of the cabinet body 100.

[0101] Optionally, as shown in FIG4 , the top plate 12 and the bottom plate 11 are respectively connected to the aforementioned first sealing member 40 on one side close to the cabinet door 30 . The first sealing member 40 is used to abut against the cabinet door 30 to prevent rainwater from entering the cabinet body 10 .

[0102] Optionally, the top plate 12 includes a main plate 121 and a mounting plate 122 . The main plate 121 is connected to the connecting plate 15 and extends toward the cabinet door 30 . The mounting plate 122 is connected to the side of the main plate 121 facing the bottom plate 11 . The mounting plate 122 is used to connect to the first sealing member 40 .

[0103] By arranging the top plate 12 to protrude from the surface of the first side plate 13 facing away from the connecting plate 15 , the gap between the cabinet body 10 and the cabinet door 30 can be shielded to prevent rainwater from flowing directly into the gap between the cabinet body 10 and the cabinet door 30 from above.

[0104] In the description of the embodiments of the present disclosure, it should be noted that the orientation or positional relationship of terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", and "outside" are based on the orientation or positional relationship described in the accompanying drawings, and are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present disclosure.

[0105] The above disclosure is only a preferred embodiment of the present disclosure, and it is certainly not intended to limit the scope of the rights of the present disclosure. A person skilled in the art can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present disclosure are still within the scope of the present disclosure.
