Embodiment Construction

[0013] Illustrate the present invention below in conjunction with accompanying drawing:

[0014] according to figure 1 , to describe in more detail the friction clutch of the present invention used in the shutter driving mechanism of the present invention.

[0015] figure 1 The inner clutch plate ID, the outer clutch plate OD and the elastic assembly SE in between are shown. The outer clutch plate OD is provided with a notch N.

[0016] Wherein, the outer diameter of the inner clutch plate ID is about 12.5 mm, and the thickness is about 4 mm. The inner clutch plate extends from a wheel that is also a guide wheel for the outer clutch plate OD. The inner diameter of the outer clutch plate OD is about 14 mm, and the thickness is also about 4 mm. The gap between the two clutch plates is 0.7 mm. In this embodiment, the elastic element SE is made of an elastic metal piece with a thickness of approximately 0.3 mm. In order to enable a more or less meandering movement of the el...

Abstract

The invention relates to a friction clutch which is used for connecting a first clutch shaft or a first clutch plate with limited moment, a second clutch shaft or a second clutch plate with limited moment and a blind window driving mechanism, wherein the clutch shaft or the clutch plate is coaxially arranged in another clutch shaft or clutch plate; the friction clutch comprises an elastic assembly connected with the two clutch shafts or clutch plates; the elastic assembly is positioned between the first clutch shaft or the first clutch plate and the second clutch shaft or the second clutch plate; and a corrugation line is arranged at the section vertical to common axis; and the whole perimeter of the corrugation line is almost in contact with the elastic assembly. According to the friction clutch, the elastic assembly is uniformly arranged between two clutch plates or shafts so as to ensure higher concentricity of the friction clutch and further improve the automaticity of the blind window driving mechanism.

Description

technical field [0001] The invention relates to a friction clutch and a shutter driving mechanism, in particular to a friction clutch used to connect a first clutch shaft or clutch plate and a second clutch shaft or clutch plate with limited torque and a shutter driving mechanism. Background technique [0002] The shutter drive mechanism and four cam discs for activating the two end position switches in the upper and lower end positions. Each cam disc has a notch for activating a switch. The cam discs and switches are arranged in such a way that only the switches are activated when both designated cam discs allow activation of the switches at the same time. The cam disc is driven by a gear stage and its input is driven by the shutter drive mechanism. After the two integrated gears and one of the clutch discs only rotate at 70 revolutions, the functions of the two notches are not the same when they are in the same position again. 70 revolutions correspond to the maximum le...
