Abstract

The invention provides an electromagnetic clutch. The electromagnetic clutch comprises an upper cover plate, a clutch gear, a return spring, an output spindle and an electromagnetic control mechanismfor controlling the clutch gear to move up and down; the output spindle is rotationally arranged on the upper cover plate; the output spindle is sleeved with the clutch gear which can move up and down; the output spindle is sleeved with the return spring; the return spring is arranged between the upper cover plate and the clutch gear; and the output end of the electromagnetic control mechanism isin drive connection with the top end of the clutch gear. By controlling the clutch gear to move up and down through the electromagnetic control mechanism, the clutch gear can be disengaged or engagedwith other transmission gears according to actual needs, and switching between a manual mode and an automatic mode of the clutch gear is achieved, and torque consumption is low.

Description

technical field [0001] The invention relates to the technical field of automatic windows, in particular to an electromagnetic clutch. Background technique [0002] The automatic window switch device is driven by a small DC motor, and the motor outputs low-speed and high-torque power through a reduction box. The interior of the reduction box is composed of a worm gear and a spur gear. The worm gear can provide a self-locking function, and the external power cannot be reversed through the gearbox to drive the motor to rotate, which also ensures the locking of the window position after the window is opened. Considering the actual use of opening the window, it is necessary to add a manual mode, unlock it, and manually open and close the window, which means that the power connection behind the gearbox needs to be cut off. [0003] In the prior art, the clutch usually applied to this motor is an electromagnetically controlled friction clutch, that is, two friction plates are attr...
