Abstract

The invention discloses a magneto-resistive clutch. The magneto-resistive clutch comprises a motor and a driven gear, wherein the driven gear controls opening-closing degree of a window through a gearset; the driven gear and a motor output shaft are engaged or are disengaged through a clutch gear set; the clutch gear set comprises a base, a drive gear which is in transmission fit to the output shaft of the motor; the drive gear is in transmission fit to the output shaft of the motor; the drive gear is coaxially connected to a first gear; the first gear is arranged on a magnet housing for accommodating a magnet; a gear ring is arranged on the base; the gear ring is engaged with the first gear; a clutch gear is fixedly connected on the base, and the drive gear is engaged with the clutch gear through transmission; a first spring for rotating and returning the base is arranged on the base; and the drive gear is a conductor made of a magneto-resistance resistant material. The drive gear islifted to the gear of the last stage for cutting magnetic lines of force of the magnet, so that cutting speed is higher, and generated acting force is stable; and moreover, the gear ring on the baseand the first gear drive the clutch gear and the driven gear to engage and separate.

Description

technical field

[0001] The invention relates to the technical field of electric doors and windows, in particular to a reluctance clutch. Background technique

[0002] As a smart home, electric windows are more and more popular among the people. There are many gear-driven electric windows on the market. Under normal electric drive, these electric windows drive the rotation shaft on the window to rotate through the rotation of the gear set, thereby realizing electric windows. Window opening and closing. In order to ensure that the electric window is not affected by external factors when the window is closed, the existing built-in window drive is equipped with a clutch. When the electric window is closed, the clutch is disconnected, so that the window cannot be rotated; when the electric window is opened, the clutch is engaged. Windows works fine.

[0003] However, the existing electric windows have the following problems: the existing clutch uses spring friction to drive the...

Embodiment Construction

[0025] The technical solutions of the various embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments described in the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work are within the protection scope of the present invention.

[0026] Embodiments of the present invention provide reluctance clutches such as Figure 1 to Figure 4 As shown, the reluctance clutch 2 includes a motor 1 and a driven gear 3. The driven gear 3 controls the opening and closing degree of the window through a gear set, and the driven gear 3 and the output shaft of the motor 1 are connected by 8 clutch gears engagement or disengagement; the clutch gear 8 groups include a base 9 and a main gear 6 that is in transmission cooperation wit...
