Problems solved by technology

However, the electromagnetic clutch device is relatively complicated, and the rotation speed is required to be low during the torque transmission process, otherwise the device will not be able to push the clutch gear to mesh with other gears in time, and then the problem of failure will occur.
[0005] For a long time, automatic door opening and closing devices have many insurmountable practical contradictions in terms of simplified structure, lightweight design, structural reliability, manufacturing cost and operating quality.

Abstract

The invention belongs to the technical field of intelligent household appliances, and particularly relates to a simple direct-drive rotary execution device and a working method thereof. The simple direct-drive rotary execution device comprises a shell, a rotary disc, a rotary shaft and a power unit, wherein the rotary shaft is rotatably arranged in the shell, and the circular rotary disc perpendicular to the rotary shaft is arranged on the rotary shaft; a magnetic substance is further arranged on the rotary disc; the power unit capable of electromagnetically driving the rotary disc is arranged on at least one side of the rotary disc, and the power unit is fixed with the shell; and the power unit comprises a group of windings. The simple direct-drive rotary execution device has the advantages of being simple and compact in overall structure, simple in transmission, free from an independent clutch device, and capable of realizing automatic door opening and closing and manual-automatic integrated functions; the power unit is free from static resistance torque, and the device is not self-locked; an electric control unit is integrally integrated with the windings, without additional wire harness connection and additional installation space, so that the overall reliability is higher; and a tooth-groove-free structure is low in counter potential waveform distortion rate, so that more accurate monitoring and judgment are facilitated.

Description

technical field [0001] The invention belongs to the technical field of smart home appliances, and in particular relates to a simple direct-drive rotary actuator and a working method thereof. Background technique [0002] At present, only a small number of door opening and closing devices used in smart home appliances on the market have realized the functions of automatic door opening and closing and manual integration. This part of the door opening and closing device usually includes an independently set clutch device, a multi-stage gear transmission mechanism, a position sensor and an electronic control unit. Although these devices cooperate with each other to realize the functions of automatic door opening and closing and manual integration, there are also some inherent problems that are difficult to overcome. defect. [0003] Clutch devices include various forms such as electromagnetic clutches and mechanical clutches. The internal structure is complex and limited by the...
