Technical Field

[0001] The utility model relates to the technical field of mine electric vehicles, and specifically, to a cab shell of a mine electric vehicle. Background Art

[0002] Mine electric vehicles are widely used in mine operations and are mainly used for transporting minerals and other materials. The existing shell structures of mine electric vehicles mainly consist of traditional car bodies, and such shell structures are mainly composed of frames, doors, and windows.

[0003] In actual use, the air intake and exhaust are mostly adjusted through glass windows and air conditioners. Although such adjustment can quickly and significantly exchange the air inside the cab with the outside air, for mine electric vehicles, their electric energy is limited and does not support continuous operation with the air conditioner on. At the same time, during the period when the air conditioner is not turned on, if the windows are opened for operation, the outside dust is relatively large, which not only affects the health of the driver but also the cleanliness of the cab.
