[0066] The following describes the implementation of the present invention through specific embodiments. People skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description and are not used to limit the scope of implementation of the present invention. Changes or adjustments in their relative relationships should also be regarded as the scope of implementation of the present invention without substantially changing the technical content.

[0068] The present invention provides a massage chair, comprising a seat frame and an intelligent massage mechanism with a massage force measurement and control function. The seat frame is provided with a guide rail, and the intelligent massage mechanism is arranged to move on the guide rail.

[0069] The structure of the above-mentioned intelligent massage movement is as follows:

[0070] like Figures 1 to 6 As shown, the intelligent massage movement with massage force measurement and control function includes:

[0071] Frame 1; Frame 1 may be in the shape of a plate or a frame;

[0072] a massage mechanism 2 for performing a massage action on the user, the massage mechanism 2 being adjustably arranged on the frame 1;

[0073] A force measuring device 3 for detecting the massage force of the massage mechanism 2, the force measuring device 3 being arranged on the frame 1;

[0074] The active traveling mechanism 4 includes a driving wheel shaft 41, an active traveling wheel 42, a transmission mechanism 43 (the transmission mechanism 43 can be a transmission or a worm gear transmission assembly), and a power device 44. The driving wheel shaft 41 is rotatably mounted on the force measuring device 3 and is repositionably floating relative to the frame 1. The active traveling wheel 42 is mounted on the driving wheel shaft 41 and is in motion with the seat frame of a massage chair. The power device 44 is connected to the driving wheel shaft 41 through the transmission mechanism 43.

[0075] The restraining member 5 is provided on the frame 1 and movably limits the power device 44 to one side of the frame 1 .

[0076] In the present invention, the driving axle 41 of the active travel mechanism 4 is rotatably mounted on the force measuring device 3 and is repositioned to float relative to the frame 1 in response to changes in the user's reaction force on the massage mechanism 2. The force measuring device 3 detects the massage force exerted by the massage mechanism 2 on the user and determines whether the massage force is within a comfortable range, thereby enhancing the therapeutic effect of the intelligent massage movement. More importantly, a restraining member 5 is mounted on the frame 1 and movably confines the power unit 44 to one side of the frame 1. Specifically, when the driving axle 41 floats relative to the frame 1, the restraining member 5 allows the power unit 44 to undergo slight movement relative to the frame 1 and effectively transmits the power of the power unit 44 to the driving axle 41 via the transmission mechanism 43. Therefore, the intelligent massage movement with massage force measurement and control function of the present invention can be provided with the force measuring device 3 between the active travel mechanism 4 and the frame 1 without affecting the power transmission between the power unit 44 and the driving axle 41. This allows the detection of the massage force exerted by the massage mechanism 2 on the user, improves the cushioning performance of the massage mechanism 2 during massage, and significantly enhances massage comfort.

[0077] like Figures 1 to 4 As shown, in order to adjust the massage intensity of the massage mechanism 2 on the user, the intelligent massage movement further includes a control system and a massage intensity adjustment device 6. The control system is in communication with the force measuring device 3 and the massage intensity adjustment device 6, respectively. The massage intensity adjustment device 6 is mounted on the frame 1 and is adjusted and coordinated with the massage mechanism 2. During massage, the force measuring device 3 detects the massage intensity of the massage mechanism 2 on the user in real time. The control system analyzes and processes the detection signal fed back by the force measuring device 3 to determine whether the massage intensity of the massage mechanism 2 on the user is within a comfortable range. If the massage intensity is not within the comfortable range, the massage intensity adjustment device 6 adjusts the position of the massage mechanism 2 relative to the frame 1 until the massage intensity is within the comfortable range.

[0078] Furthermore, to achieve adjustment and coordination between the massage force adjustment device 6 and the massage mechanism 2, the massage mechanism 2 includes a bearing shaft 21 and a massage arm assembly 22 (the massage arm assembly 22 performs massage actions such as kneading and tapping on the user). The bearing shaft 21 is mounted on the frame 1, and the massage arm assembly 22 is swingably mounted on the bearing shaft 21. The massage arm assembly 22 is provided with an arcuate rack 23. The massage force adjustment device 6 includes an adjustment drive 61, an adjustment shaft 62, and an adjustment gear 63. The adjustment drive 61 is mounted on the frame 1, and the adjustment shaft 62 is rotatably mounted on the frame 1 and is in transmission connection with the adjustment drive 61. The adjustment gear 63 is fixedly mounted on the adjustment shaft 62 and meshes with the arcuate rack 23. When the adjustment drive 61 drives the adjustment shaft 62 to rotate in a fixed direction, the adjustment gear 63 rotates in a fixed direction with the adjustment shaft 62, and the arcuate rack 23 swings under the drive of the adjustment gear 63, thereby changing the position of the massage arm assembly 22 relative to the frame 1, thereby adjusting the massage force of the massage mechanism 2 on the user. Furthermore, the center of the circle corresponding to the arcuate rack 23 is located on the axis of the support shaft 21. With this arrangement, the arcuate rack 23 swings about the support shaft 21, thereby causing the massage arm assembly 22 to swing about the support shaft 21. The adjustment drive device 61 can be a motor, and an adjustment transmission (which can be a transmission or a worm gear transmission assembly) can be provided between the adjustment drive device 61 and the adjustment shaft 62.

[0079] like Figure 5As shown, in order to simplify the structure of the restraint 5, the restraint 5 includes a sleeve portion 51, an intermediate flexible portion 52, and a base portion 53 connected in sequence. The sleeve portion 51 is movably mounted on the power unit 44, and the base portion 53 is mounted on the frame 1. The intermediate flexible portion 52 is preferably made of a material with good flexibility so that it can effectively restrain the power unit 44. For example, when the power unit 44 swings toward the frame 1 with the driving wheel shaft 41 as the swing center, the intermediate flexible portion 52 can effectively support the power unit 44; when the power unit 44 swings away from the frame 1 with the driving wheel shaft 41 as the swing center, the intermediate flexible portion 52 can effectively pull the power unit 44. In some embodiments, since the power unit 44 includes a cylindrical power body 441 and an output shaft extending from the power body 441, the sleeve portion 51 is annular and is loosely mounted on the power body 441. In some preferred embodiments, in order to reduce the contact area between the above-mentioned hanging portion 51 and the power body 441, the above-mentioned hanging portion 51 includes a circumferential ring 511, and the inner peripheral wall of the circumferential ring 511 has a radially inwardly protruding abutting flange 512. With this configuration, the contact area between the above-mentioned hanging portion 51 and the power body 441 is greatly reduced, and even linear contact is formed, thereby improving the heat dissipation efficiency of the power body 441 and facilitating the power body 441 to slide or tilt slightly relative to the hanging portion 51. Furthermore, the contact area between the above-mentioned abutting flange 512 and the power body 441 is arc-shaped, which can reduce the friction between the above-mentioned power body 441 and the hanging portion 51.

[0080] To facilitate transmission of power from the power unit 44 to the driving shaft 41, the transmission mechanism 43 includes a housing 431, a worm gear 432, and a worm 433. The housing 431 rotatably engages with the driving shaft 41. The worm gear 432 is located within the housing 431 and fixedly mounted on the driving shaft 41. The worm 433 rotatably engages within the housing 431 and meshes with the worm gear 433. The power unit 44 includes a power body 441 and an output shaft extending from the power body 441. The power body 441 is fixedly coupled to the housing 431, and the output shaft is coaxially fixedly coupled to the worm 433. Under the constraints of the restraint 5, the power body 441 does not rotate about the driving shaft 41.

[0081] like Figure 4 and Figure 6 As shown, the number of the force measuring devices 3 can be multiple. For example, when there are two force measuring devices 3, the driving wheel shaft 41 rotates and passes through the two force measuring devices 3 at the same time. The specific structure of the force measuring device 3 is as follows:

[0082] The above-mentioned force measuring device 3 mainly includes a device body 31, a moving body 32, a reset elastic member 33, a sensed body 34 and a sensor 35. The device body 31 is arranged on the frame 1, the moving body 32 is slidably arranged on the device body 31, and the moving body 32 is provided with a through hole 321 for the driving wheel shaft 41 to pass through. The reset elastic member 33 is arranged between the device body 31 and the moving body 32, the sensed body 34 is arranged on the moving body 32, and the sensor 35 is arranged on the device body 31 to detect the distance between the sensor 35 and the sensed body 34.

[0083] To simplify the structure of the device body 31, the device body 31 includes a housing 311 and a cover 312. The housing 311 defines a sliding cavity 311a with a single-side opening for the sliding member 32. The cover 312 is located at the opening of the sliding cavity 311a. The sensor 35 is located on the cover 312. The two ends of the return spring 33 in the extension direction respectively abut against the moving member 32 and the bottom of the sliding cavity 311a. The cover 312 is located at the opening of the sliding cavity 311a to prevent the moving member 32 from slipping off the housing 311. To improve the stability of the moving member 32 during sliding, the cross-section of the sliding cavity 311a is adapted to match the cross-section of the moving member 32. For example, when the sliding cavity 311a is cylindrical, the moving member 32 is cylindrical. In addition, symmetrically disposed on opposite sides of the housing 311 are provided with avoidance holes 311b that allow the driving wheel shaft 41 to float, thereby preventing movement interference.

[0084] The detection principle of the force measuring device 3 is as follows:

[0085] When the massage mechanism 2 is treating the user, the user applies a reaction force of equal magnitude to the massage mechanism 2. Because the driving wheel shaft 41 is movably mounted on the seat frame of the massage chair via the driving travel wheels 42, and the massage mechanism 2 is mounted on the frame 1, when the user indirectly applies a reaction force to the frame 1 via the massage mechanism 2, the frame 1 and the device body 31 float together in a direction parallel to the direction of the reaction force. In other words, when the user applies a reaction force to the massage mechanism 2, the driving wheel shaft 41 and the moving body 32 float together relative to the device body 31 or the frame 1 (using the seat frame of the massage chair as a reference, the driving wheel shaft 41 and the moving body 32 do not float, but the device body 31 and the frame 1 do). The return elastic member 33 undergoes expansion and contraction deformation due to the movement of the moving body 32. When the moving body 32 slides, the position of the sensed body 34 relative to the sensor 35 changes. The sensed body 34 detects the distance between itself and the sensed body 34, and obtains the deformation of the reset elastic member 33. The pressure on the reset elastic member 33 is calculated based on the deformation of the reset elastic member 33 and Hooke's law, and then the reaction force of the user on the massage mechanism 2 is calculated, thereby detecting the massage force of the massage mechanism 2 on the user (the massage force can be the magnitude of the force or the magnitude of the torque).

[0086] To reduce friction between the driving wheel shaft 41 and the moving body 32, the driving wheel shaft 41 is inserted into the through hole 321 of the moving body 32 via a bearing. The moving body 32 is preferably made of a material with medium hardness (Shore hardness 65-85) and good wear resistance (such as PP). To further reduce friction, the surface of the moving body 32 is machined to be smooth, and the surface of the sliding cavity 311a can also be machined to be smooth. Furthermore, the surfaces of the sliding cavity 311a and the moving body 32 can be coated with a lubricant.

[0087] If the sensed object 34 is a magnetic object (e.g., a magnet), the sensor 35 is a magnetic sensor (e.g., a linear Hall sensor). The resilient member 33 may be a spring or elastic rubber. The sensed object 34 may be fixed to the outer wall of the moving body 32 or embedded within the moving body 32. For example, the moving body 32 may be provided with a recess that matches the shape of the sensed object 34, and the sensed object 34 may be disposed within the recess.

[0088] When the induced object 34 is a magnet and the sensor 35 is a magnetic sensor, in order to prevent the materials of the device body 31, the reset elastic member 33 and the moving body 32 from affecting the detection accuracy, the device body 31, the reset elastic member 33 and the moving body 32 should be made of non-ferromagnetic materials. For example, the device body 31 is made of aluminum alloy material, and the reset elastic member 33 is made of stainless steel material. Aluminum alloy and stainless steel materials do not contain ferromagnetic components.

[0089] Finally, in another preferred embodiment of the massage chair, the guide rails provided on the seat frame are racks extending along the seat frame. Based on this, the active travel wheel 42 of the active travel mechanism 4 is designed as a travel gear, which meshes with the rack. The seat frame is also provided with a guide groove. Based on this, the intelligent massage mechanism also includes a driven travel mechanism 7, which includes a driven wheel shaft 71 and driven travel wheels 72. The driven wheel shaft 71 is provided on the frame 1, and the driven travel wheels 72 are provided on the driven wheel shaft 71 and roll in engagement with the guide groove, thereby improving the smoothness of the movement of the intelligent massage mechanism.

[0090] In summary, the intelligent massage mechanism and massage chair with massage force measurement and control functions of the present invention enable the installation of a force measuring device between the active travel mechanism and the frame, without affecting the power transmission between the power unit and the active wheel shaft. This allows the detection of the massage force exerted by the massage mechanism on the user, thereby improving the cushioning performance of the massage mechanism during massage, and significantly enhancing massage comfort. Therefore, the present invention effectively overcomes the various shortcomings of the prior art and possesses high industrial value.

[0091] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
