SWING

摘要

A swing comprising a frame bracket (1), a balance wheel (2), a swing plate (3), a magnetic fluid drive apparatus (4), and a controller (5). The balance wheel (2) is provided with a centric shaft (6), a swing eccentric shaft (7), and a swinging eccentric shaft (8). The swing eccentric shaft (7) and the swinging eccentric shaft (8) are arranged at different positions of the balance wheel (2). The centric shaft (6) of the balance wheel (2) is fittingly connected to a bearing base (9) of the frame bracket (1). The magnetic fluid drive apparatus (4) comprises a cylinder (11), a piston (12), a piston rod (13), a magnetic fluid (14), and an electromagnetic coil (15). The piston (12) and the magnetic fluid (14) are arranged within a cavity of a cylinder body (11). The cylinder body (11) is pivotally connected to the frame bracket (1). The piston rod (13) is pivotally connected to the swinging eccentric shaft (8). The controller (5) is utilized to control the piston (12) and the piston rod (13) to move upward/downward in the magnetic fluid (14) according to the rhythm of a children's music. The piston rod (13) is utilized to drive the balance wheel (2) to swing with the rhythm of the children's music. The balance wheel (2) and the swing eccentric shaft (7) are utilized to drive the swing plate (3) to swing according to the rhythm of the children's music. This allows a child to swing with the children's music on the swing, thus enhancing an interest in swinging on the swing.
