The working principle of the massage apparatus having a pressure sensing and adapting drive mechanism of the present invention is as follows:
As both the malaxation part and pummeling part are provided on the left and right clamp plates 1, the working stroke of the malaxation part and pummeling part is completely controlled by the working stroke of the left and right clamp plates 1. While the working stroke of the left and right clamp plates is controlled by the pressure sensing and adapting drive 28. Take the massage head as an example, when the pressure sensing and adapting drive 28 begins to work, the massage head 7 will stretch forward to the limit point. Change the forward stretch force of the massage head 7 by changing the rotation of the electric motor, and the forward stretching pressure is the pressure of the massage head to touch human body. The forward stretch force is related with the rotation of the electric motor. The higher the rotating speed is, the bigger of the forward stretch force is, or vice versa. The forward stretch force is set beforehand. Usually two parameters will be set, one is the lowest rotating speed of the motor which is corresponding with the minimum forward stretch force, the other is the highest rotating speed of the motor which is corresponding with the biggest forward stretch force. The user can adjust the settings of the two parameters by turning up and turning down (or the smallest or biggest) freely (it can be controlled by the rotary button on the massage apparatus), til the user feel comfortable.
The loading force is defined as the resistance encountered by the massage head 7 when it offers massage to human body, and the loading force will be different between different body types. When the forward stretch force is set (the forward stretch force will be set where the user's rotary button is located), during the application, if the loading force is smaller than the forward stretch force, the motor 31 will rotate clockwise and drive the driving impeller 285 to rotate clockwise, and get the driven impeller 286 to rotate clockwise, so as to drive the movement of the left and right clamp plates 1, and the left and right clamp plates 1 will drive the massage head 7 to stretch forward. When the loading force is equal to the forward stretch force, the driven impeller 286 will stop rotating, so that the massage head 7 will stop stretching forward. If the user's body type changes, such as the back curve changes, the loading force might be bigger than the forward stretch force. When the loading force is bigger than the forward stretch, the driven impeller 286 will also rotate anti-clockwise (forced by the loading force), so as to drive the massage head 7 to draw back til the loading force is equal to the forward stretch force.
The massage apparatus having a pressure sensing and adapting drive mechanism of the present invention is mainly used for massage chair or massage bed. It can feel the massage pressure automatically, and can adjust the massage pressure within the setting pressure range automatically in real time according to different body types of the users. The massage apparatus can automatically adapt to changes in the height and the curvature of the back of human body in the course of massaging, performing manipulation, malaxation, pummeling and finger pressure massage on a person of anybody type, and the massage pressure can be set freely. The user leans his back on the back of the massage chair or lies on the back of the chair. The back of the chair supports the user's body, then the apparatus can provide real-time massage to the user's back according to the massage procedures and pressure set by the user, and the massage pressure can be adjusted, realizing that the machine automatically adapts to body type to provide pleasant massage service. This totally change the rigid keenly feel of the existing massage chair which provides massage service by using the massage head to support human back.
