The two ears 7K2 hold the pressure sensor 11, and a pair of screws are passed through and arranged in the passage 11B along both sides, by which the suspended end of the pressure sensor 11 and the trip 7K are connected by a pivot pin structure. By the cooperation of the pressing convex part 7K3 and the accommodating groove part 11C, the pressing force generated by the axial movement of the worm 7H can be concentrated in the accommodating groove part 11C, so that the pressure data detected by the pressure sensor 11 can be more accurate. The motor shaft of the strong and weak driving motor 7D comprises a first motor shaft section L1 and a second motor shaft section L2 which are adjacently arranged along the axial direction, and the first motor shaft section L1 is positioned between the driving end of the strong and weak driving motor 7D and the second motor shaft section L2. The worm 7H is sleeved on the periphery of the first motor shaft section L1 through a spline sleeve 7L, and is sleeved on the periphery of the second motor shaft section L2 through a composite shaft sleeve 7G. The worm 7H has a mounting hole extending in the axial direction thereof, and the mounting hole includes a relief space between the second motor shaft segment L2 and the worm 7H, and the elastic member 10 is disposed in the relief space and abuts between the second motor shaft segment L2 and the worm 7H.

In the initial state, the elastic member 10 is in a compressed state to eliminate the play between the respective members. The worm 7H has a first worm section meshing with the worm wheel 7F and a second worm section fitted in the support bearing 7I. The support bearing 7I of the present embodiment is a deep groove ball bearing, an inner ring of which is fixedly mounted on the worm 7H, and an outer ring of which is embedded in the bearing seat 7M, and the support bearing 7I moves in the axial direction along with the worm 7H.

When the user leans on the massage device 5, the body pressure is transmitted to the worm wheel 7F through the massage head and the massage arm of the massage device 5, the fluted disc 7C, the gear piece 7B and the strong and weak driving shaft 7A, the worm wheel 7F rotates and drives the worm 7H to generate displacement change along the axial direction, so that the deformation degree of the elastic piece 10 changes, and meanwhile, the pressure sensor 11 outputs pressure data under the pushing action of the thrust bearing 7J and the touch piece 7K. When the user leaves the massaging device 5, the elastic member 10 is reset, so that the worm 7H is reset. Due to the matching effect of the spline sleeve 7L, on one hand, a motor shaft of the strong and weak driving motor 7D can normally drive the worm 7H to rotate, and on the other hand, the worm 7H can independently move relative to the motor shaft. If the matching mode of the motor shaft and the worm is adjusted, and the strong and weak driving motor 7D with the motor shaft capable of moving along with the worm 7H is selected, the strong and weak driving motor 7D of the type requires that the motor shaft can move along the axial direction and can stably rotate, the performance requirement is high, and a common motor shaft cannot move along the axial direction, so that the design mode of the embodiment is favorable for reducing the performance requirement on the strong and weak driving motor 7D.

The walking driving motor 9C drives the first walking shaft 9A to rotate by the cooperation of the walking driving worm and the walking driving worm wheel. Rolling parts matched with the guide rail frame of the massager are respectively arranged on two sides of the two walking shafts.

The massage machine core is further provided with a walking detection device for detecting the number of turns of the first walking shaft 9A, a kneading position detection device for detecting the left and right moving positions of the massage arm 5A, and a telescopic position detection device for detecting the front and rear swinging positions of the massage arm 5A, wherein the detection devices are usually photoelectric encoders, which are conventional technologies and therefore are not described again.

The above is the first embodiment of the present application, but it is easily understood that the technical idea of the present application is not limited to the above embodiments. In another embodiment, the toothed disc may not swing back and forth about the first travel shaft 9A, but may be adjusted to swing about the kneading drive shaft, even if the kneading drive shaft is supported between the two cantilevers.

The application also provides a massage machine, which is provided with a guide rail frame and a massage machine core arranged on the guide rail frame; the massage machine core is the massage machine core. The massage machine is, for example, a massage chair.

In the present embodiment, a strain gauge (semiconductor strain) for detecting displacement is an element for measuring strain, which is formed of a sensitive grid or the like. The working principle of the resistance strain gauge is based on the strain effect, that is, when a conductor or a semiconductor material is mechanically deformed under the action of external force, the resistance value of the conductor or the semiconductor material is correspondingly changed, and the phenomenon is called the strain effect. The strain gauge is used for indirectly sensing the external force to be measured by sticking a strain gauge on an elastic sensitive element. The elastic sensitive elements with different configurations can be used for measuring the mechanical quantities of displacement, stress, strain, pressure, torque, acceleration and the like of various objects. While in other embodiments, other types of displacement sensors, such as capacitive sensors, inductive sensors, resistive sensors, etc., may also be employed.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
