The invention discloses a transmission mechanism for a car sunroof flexible shaft. The transmission mechanism comprises the car sunroof flexible shaft and a rotating motor, wherein the car sunroof flexible shaft comprises a flexible shaft core wire and a steel wire spirally wound around the flexible shaft core wire, the steel wire forms external threads on the outer surface of the flexible shaft core wire, the car sunroof flexible shaft is sleeved with a connecting piece, the connecting piece is in threaded connection with the external threads through internal threads, the connecting piece isfixedly connected with a first gear in a sleeve mode, and the output end of the rotating motor is provided with a second gear meshing with the first gear. According to the transmission mechanism, through ingenious thread matching, and the second gear is driven by the rotating motor to drive the first gear, so that the flexible shaft is promoted to move, the transition is carried out through the connecting piece, noise is reduced by replacing original wool, the cost is reduced, and the transmission efficiency is high.
Description
technical field [0001] The application relates to the field of automobile sunroofs, in particular to a transmission mechanism for a sunroof flexible shaft. Background technique [0002] The flexible shaft transmission mechanism is an important part of the sunroof. It is arranged on the guide rail and is used to control the power actuator of the sunroof glass lifting and opening and closing. The flexible shaft usually consists of a flexible shaft core wire, a steel wire and a woolen wire. The steel wire is spirally wound on the flexible shaft core wire. between to reduce noise. [0003] At present, the wool used on the flexible shaft is purchased through imports, and its cost is relatively high. Therefore, how to reduce the cost while reducing noise is the direction of current research. Contents of the invention [0004] The object of the present invention is to provide a transmission mechanism for a sunroof flexible shaft to overcome the shortcomings in the prior art. ...
