Electric sunshade curtain convenient to disassemble and assemble

Abstract

The utility model relates to an electric sunshade curtain convenient to disassemble and assemble, which comprises a motor, the motor transmits power to a driving wheel through a connecting rod, the driving wheel is meshed with a driven wheel in a gear box to transmit power, an outer gear is arranged at one end of the driving wheel, the tooth crest of the outer gear is a triangular spire surface, and an arc-shaped transition surface is arranged at the corner of the outer gear. A square inner cavity for transmitting power is formed in the end face of the driving wheel; the inner wall of the driven wheel is provided with an inner gear with the same tooth shape as the outer gear, and the tooth pitch of the inner gear is half of that of the outer gear. A triangular spire surface is arranged on the tooth crest of an outer gear, an arc-shaped transition surface is arranged at the corner, an inner gear meshed with the outer gear is also provided with the same tooth shape, and meanwhile the tooth pitch of the inner gear is designed to be half of the tooth pitch of the outer gear. According to the novel structure, when the external gear and the internal gear are assembled, the external gear and the internal gear can be smoothly inserted and meshed, so that a motor and a synchronizing wheel which are arranged behind the external gear and the internal gear can be smoothly assembled, and convenience is brought to installation.
