Description

Technical Field

[0001] The invention relates to a massage bed, in particular to a massage bed and a control method thereof, belonging to the technical field of massage equipment. Background Art

[0002] Massage beds are commonly used automatic massage devices, which are usually used to massage the body in a lying position. Currently, common massage beds include those disclosed in CN101278877B (massage bed) that use massage wheels to massage along the entire length of the bed, and those disclosed in CN102119906Bg ( The new massage bed adopts a linear drive mechanism to drive the massage head to move for massage. In the existing massage head movement for massage, the motor is generally used for reversing. Frequent reversing of forward and reverse directions is easy to damage the capacitor in the circuit, which brings problems in use, maintenance and cost to the equipment. In addition, the configuration of the current massage bed equipment is generally fixed. Once the equipment is manufactured, the number of massage heads cannot be changed, which limits the subsequent expansion of the equipment. In addition, the current mobile massage heads generally move at a set speed and cannot work without the drive device. Freestyle massage is performed on the human body, and the massage intensity is inconvenient to adjust. In addition, the current massage head movement trajectory is generally a circular trajectory. The circular motion trajectory refers to the massage action along a complete circular path. This trajectory usually requires light contact with the skin during massage, and circular motion is performed with uniform force and speed. It aims to achieve a soothing effect through the principle of skin moving but flesh not moving, that is, the force is light and does not drive deep tissue movement. The massage effect on deep tissue and specific pain points and areas is poor. Summary of the invention
