For this reason, various electric beds are constantly emerging in the market. Electric beds are a new type of bed with a changeable bed shape. Traditional electric beds include a flippable movable bed board and a driving device installed inside the electric bed, such as an electric push rod, which is used to lift and lower the flippable movable bed board to adjust the bed shape.

[0003] Studies have found that vestibular stimulation can not only relax the emotions of infants and young children, but is also effective for adults. Therefore, a bed with a cradle function can help people with insomnia relax and fall asleep quickly to a certain extent. In the prior art, the smart electric bed with a rocking function usually has a motor that drives the bed to rock, which is usually installed on the bed frame. The motor will generate vibration and noise during operation, thereby affecting the quality of sleep. In addition, the existing smart electric beds are usually disassembled into multiple parts during production and transportation, and then assembled by screwing.
