Baby cot with ferrofluid rocker mechanism actuated by electromagnetic force

Abstract

The invention discloses a crib with an electro-magnetic driving magnetofluid wabble mechanism. The crib comprises a base, a cardo ring and a crib body, wherein the cardo ring connects the base with the crib body through rotating shafts; an electromagnet array formed by a plurality of electromagnets is fixed at the bottom of the crib body; the crib further comprises a crib bottom cover plate; a sealed oil bag is arranged at the center of the bottom end of the crib bottom cover plate; the oil bag is filled with edible oil and ferroferric oxide powder; when the crib bottom cover plate covers the opening of a cavity, the inner surface of the oil bag is clung to iron cores of the electromagnets in the electromagnet array; a main control module is fixed between the surface and the bottom of the crib body; the electromagnet array is connected with the main control module. According to the crib with the electro-magnetic driving magnetofluid wabble mechanism, the magnetofluid control technology is utilized and various safety measures are adopted, so that the sleeping environment of a baby is improved, meanwhile, as green renewable energy sources are fully utilized, a strong practicability is achieved.

Description

Technical field [0001] The utility model relates to a baby bed, in particular to a baby bed with an electromagnetically driven magnetic fluid swing mechanism. Background technique [0002] With the improvement of people's living standards, there are higher requirements for the sleeping environment of infants and young children. When the baby is in the mother's body, it is in the amniotic fluid environment, and the mother's movement forms periodic shocks, which can comfort it. After the baby is born, it is easy to fall asleep in the gently swinging arms, which reflects that the swinging action can simulate the amniotic fluid environment and make the baby feel safe. [0003] Commercially available rocking beds use a motor-driven rocking mechanism. The motor and mechanical structure will produce noise during work, and long-term use will affect the baby’s hearing development; if the swing amplitude and frequency are not well controlled, it will also harm the baby’s health. Injury, se...

AI Technical Summary

Problems solved by technology

[0003] Commercially available rocking beds use motor-driven rocking mechanisms. The motors and mechanical structures will generate noise during work. Long-term use will affect the baby's hearing development; if the swing amplitude and frequency are not well controlled, it will also be harmful to the baby's health. Injury, serious can cause intussusception, concussion, fracture and other catastrophic injuries
