Embodiment Construction

[0027] Such as figure 1 , 2 As shown in or 3, an electromagnetic rocking chair includes a fixed part 10 and a moving part 20 that moves relative to the fixed part 10, and three fixed magnets are arranged on the fixed part 10, which are respectively: the first fixed magnet L1, The second fixed magnet L2 and the third fixed magnet L3 are electromagnets whose magnetic pole directions can be controlled separately. The moving part 20 is provided with a moving magnet 22 matched with the fixed magnet, the moving magnet 22 is a permanent magnet, and the number of the moving magnet 22 is two. The fixed part 10 is provided with a displacement detection sensor for detecting the motion state of the moving part 20, and the number of the displacement sensors is four, which are respectively: a first displacement detection sensor 121, a second displacement detection sensor 122, The third displacement detection sensor 123 and the fourth displacement detection sensor 124 . The second displac...

Abstract

The invention discloses an electromagnetic rocking chair. The electromagnetic rocking chair comprises a fixed portion and a movable portion, wherein the movable portion moves relative to the fixed portion; the fixed portion is provided with more than two fixed magnets; the fixed magnets are electromagnets of which magnetic pole directions can be respectively controlled; and the movable portion is provided with moving magnets matched with the fixed magnets. The fixed magnets are electrified, so that the magnetic pole directions of the fixed magnets are fixed, the upper ends of the fixed magnets are S poles, and the lower ends of the fixed magnets are N poles. The upper ends of the moving magnets are N poles, and the lower ends of the moving magnets are S poles. When the moving magnets move to positions right above the fixed magnets, the fixed magnets are electrified to generate magnetic force, repelling force is generated due to homopolar repulsion, and the repelling force and moving inertia of the moving magnets form resultant force which pushes the rocking chair to move smoothly.

Description

technical field [0001] The invention relates to a rocking chair, in particular to an electromagnetic rocking chair. technical background [0002] The electric cradle is based on the traditional cradle, adding an electric system so that the parents who take care of the baby can reduce the heavy labor, a kind of mother-baby electrical appliance that simulates the traditional artificial cradle. Before the baby is born, the fetus floats in the amniotic fluid of the mother’s uterus, and the mother’s body position changes such as getting up, lying down and walking around are all shaking stimuli. signal to promote brain development. After the fetus is born, the stimulation signal to receive shaking suddenly disappears, which makes the baby feel uneasy, and thus creates the need to be shaken again. Babies get a sense of satisfaction from being rocked. The latest research shows that for babies who are often shaken, the brain develops at a gratifying speed. In just one year, the we...
