Cover assembly
The present application relates to a cover assembly including a housing, a cover, a drive member, a first transmission member, and a second transmission member. The housing has a cavity. The cover has a closed position and an open position. The cover closes a door plate opening of a door plate when the cover is in the closed position and the door plate opening is exposed when the cover is in the open position. The drive member is movable relative to the housing. The first transmission member is rotatably connected with the cover and is rotatably connected with the drive member. The second transmission member is rotatably connected with the cover and is rotatably connected with the drive member. The drive member, the first transmission member, the second transmission member and the cover collectively form a linkage and are configured to drive the cover to move relative to the housing between the closed position and the open position. The cover assembly of the present application can prevent the cover in a closed state from being opened due to external force, and no additional locking means need to be provided. Furthermore, a cover in the open position is arranged parallel to a cover in the closed position, which can save space occupied by the cover assembly in a vehicle.
