Document Type and Number:
WIPO Patent Application WO/2021/031481
Kind Code:
A1
Abstract:
A power assembly (100) for an electric drying rack and an electric drying rack, comprising a winch (01), a winch base (02) and an elongated motor (3); the elongated motor (3) comprises a body (03) and an output shaft (04); the winch (01) comprises a wire groove section (011) for winding a steel wire rope and a transmission section (012) provided with an external thread; a mounting hole (023) with an internal thread is provided on the winch base (02), the transmission section (012) is inserted into the mounting hole (023), and the external thread of the transmission section (012) is fitted with the internal thread of the mounting hole (023); the winch (01) is sleeved on the body of the elongated motor (3), and the winch (01) can rotate relative to the body (03); the output shaft (04) of the elongated motor (3) is fixed to an inner hole of the transmission section (012) in a snap-fitting manner; the output shaft (04) of the elongated motor (3) drives the winch (01) to rotate, the transmission section (012) is subjected to a thread displacement within the mounting hole (023), and the wire groove section (011) is subjected to a displacement following the transmission section (012). Thus, the space occupied by the motor (3) is saved, avoiding an excessively large volume of the power assembly (100), and a shaft base for standing the winch (01) is omitted, simplifying the internal structure.
