The utility model relates to an electric passenger car roof wind window, which is characterized in that two sliding seats are arranged at two sides of the bottom face of the window coping; wherein, the sliding seat is movably provided with two sliders, while the outer sides of the two sliders are respectively and rotationally fitted with one end of a support board at the same side, while the other end of the support board is fitted with the opening of the head wind window rotationally; and the inner sides of the two sliding boards are respectively connected with an electric drive opening and closing operating gear arranged on the bottom face of the skylight coping through a connecting rod which is articulated with the inner sides; the electric drive opening and closing operating gear is adopted to drive two connecting rods to move along the preset runner, and thus controlling and releasing according to different rotation directions. The driver sitting on the drive position operates the button to control the front rotation or reverse rotation of the electromotor so as to complete the operation of full closing, front opening and back opening as well as full opening, quite simple to operate, pragmatic and more human oriented. The opening and closing of the utility model fully depends on the contraction of the connecting rod, thus free of elasticity problem, and the motion is rather slow so as to eliminate noises.
