Large-swinging force low-power consumption natural-swinging driving device

Abstract

The invention aims at providing a large-power natural-swinging driving device, which comprises an AC / DC power module, a main control module, an electromagnetic driving module and a lever module, wherein the AC / DC power module converts mains supply AC to safe low-voltage DC and provides power for a main control board and a driving board; the main control module provides driving signals to the driving module; the driving module does not need a motor; the driving device enables a swinging arm to keep a swinging movement in an electromagnetic induction transmission mode; when the swinging arm swings to different positions, the magnitudes and the directions of magnetic field forces of the swinging arm are different, a resonance movement is formed with inertia, and the operation is safe; due tothe arc design of two poles of an electromagnet, the magnetic field forces of a permanent magnet at the two poles of the electromagnet are uniform and smooth, and the swinging is natural; and the lengths of a power arm and a resistance arm of the lever module are adjustable, the swinging module can swing people or objects of different masses, and different amplitudes of swinging can be executed.

Description

【Technical field】 [0001] The present application relates to a swing drive device, in particular to a natural swing drive device with large swing force and low power consumption, which is used in fields such as electric rocking chairs, electric swing swings, and industrial automation swing devices. 【Background technique】 [0002] The swing drive device is a device that uses external force to drive the swing arm to swing. Used in rocking chairs, electric swings, industrial automation and other fields. The large swing driving device currently on the market is driven by a motor. The motor drive needs the motor to rotate in real time and transmit the swing force through the mechanical device. During the whole swing cycle, the swing force output by the motor remains unchanged, making the swing stiff, and the person being rocked feels very passive. The motor drive is always working during the complete cycle. Waste electricity. The noise emitted by the high-power motor-driven dri...
