Description
Technical Field
[0001] The utility model relates to the technical field of smart home, in particular to a massage lumbar support mechanism and an electric bed. Background Art
[0002] With the acceleration of the modern life rhythm, it has become normal for people to maintain sitting and standing postures for a long time in work and daily life. This posture, especially when accompanied by incorrect sitting postures, will cause continuous pressure and burden on the waist. In the long run, this may lead to lumbar muscle fatigue, lumbar muscle strain, and even more serious spinal injuries and diseases. These problems not only affect personal physical health but also may cause inconvenience to work and daily life.
[0003] Although some posture-adjustable electric beds and electric chairs have emerged on the market, which can provide a more comfortable reclining experience to a certain extent, these products often neglect the special support and backing for the waist. When the posture of the user changes, the lumbar support of these devices often cannot be adjusted adaptively in time, resulting in the lack of necessary support for the waist and the inability to effectively disperse and relieve pressure.
[0004] In addition, although the existing lumbar support technologies can provide support and protection for the waist to a certain extent, they usually lack massage functions and cannot further relieve lumbar fatigue. After sitting for a long time or using improper sitting postures, the lumbar muscles are prone to tension and fatigue and require appropriate massage to relax and regain vitality. However, the existing lumbar support mechanisms often cannot meet this requirement, limiting their potential in protecting lumbar health. Summary of the Utility Model
