A control method and swing mechanism for an infant and child swing |
摘要 |
A swing mechanism for an infant and child swing includes a swing arm, a swing angle adjustment assembly and a PWM motor driving unit. The swing arm is driven by a motor for swinging forth and back in a first direction and a second direction. The swing angle adjustment assembly includes a knob, a connecting arm and a sensor, wherein the knob is associated with the sensor by the connecting arm thereby moving the sensor to a reference point at a swing height of the infant and child swing by turning the knob. The PWM motor driving unit inputs an adjustable voltage to the motor for driving the swing arm, and interrupting the adjustable voltage thereafter when the swing arm arrived the reference point in the first direction. A method for controlling the infant and child swing uses the swing mechanism as described above. |
