3D massage device for massage chair

Abstract

The invention discloses a 3D massage device used for a massage chair. The 3D massage device comprises a baseplate, an upper and lower walking mechanism, an adjusting mechanism and a massage movement, wherein the upper and lower walking mechanism is matched with a gear and a tooth rack to realize walking, and rotates through a walking optical grating disc matched with a gear shaft; a plurality of optical grating holes are formed in the walking optical grating disc; the adjusting mechanism drives an adjusting sliding block to move, so as to drive an adjusting arm to rotate, realize angle adjusting of the message movement and finally realize the adjusting of the massage intensity and massage depth. According to the invention, the swaying angle of a massage plate of the massage movement is relatively big, the available massage range is relatively wide; the positioning of the massage movement on the upper and lower walking mechanism is very accurate, the working accuracy and safety property of the massage chair are improved, and the adjusting mechanism realizes accurate control on the massage intensity and the massage depth.

Description

technical field [0001] The invention relates to a 3D massage device for a massage chair. Background technique [0002] Manual massage can dredge the meridians, circulate qi and blood, and maintain the balance of yin and yang in the body. The existing massage chairs use mechanical rolling force and mechanical force extrusion to simulate human massage techniques, kneading and massaging the human body. You can feel the muscles relax, the joints are flexible, make people refreshed, eliminate fatigue, and play an important role in ensuring physical health. The massage head of ordinary massage chairs on the market cannot be adjusted back and forth, so the strength and depth of the massage cannot be adjusted. In response to this defect, a class of advanced massage chairs has appeared on the market. This type of massage chair has a 3D massage function, so-called 3D massage.

AI Technical Summary

Problems solved by technology

The massage head of ordinary massage chairs on the market cannot be adjusted back and forth, so the strength and depth of the massage cannot be adjusted. In response to this defect, a class of advanced massage chairs has appeared on the market. This type of massage chair has a 3D massage function, so-called 3D massage. The massage function means that on the basis of ordinary kneading, beating massage and up-and-down adjustment, the left and right massage heads can be stretched back and forth, which can bring deep massage

The defects of existing massage chairs with 3D massage function are: the structure of the adjustment mechanism of 3D massage function is complex, and the strength and depth of massage cannot be accurately and effectively controlled, and the swing angle of the kneading plate is small, resulting in a relatively small range of massage. Narrow, the position judgment of the massage movement on the upper and lower travel mechanism and the movement distance control of the massage movement are not accurate
