Title:
COMPLEX CLUTCH APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/058420
Kind Code:
A1
Abstract:
A complex clutch apparatus according to the present invention comprises: a rotating block provided with a central shaft extending upward and an upward inclined protrusion which surrounds the lower portion of the central shaft and is spaced a certain distance from the central shaft; a C-type plate spring which surrounds the outer circumference of the upward inclined protrusion and comes into close contact, elastically, with the outer surface of the upward inclined protrusion; a clutch gear provided with a downward inclined protrusion which is press-fitted between the central shaft and the upward inclined protrusion when the upward inclined protrusion has been inserted downward, and a stopper protrusion which is inserted between both ends of the C-type plate spring in the lengthwise direction; and an elastic body which is fixedly coupled to the central shaft and applies a downward elastic force to the upper surface of the clutch gear. The complex clutch apparatus according to the present invention can generate a large clutch force even when a product is miniaturized, because the clutch force is generated from various parts, and elements for generating the clutch force may be manufactured by using various kinds of materials, and thus, there are the advantages of reducing manufacturing costs and improving the degree of freedom in designing.
