[0023] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0024] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0025] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0026] refer to Figures 1 to 5 The adjustable massage chair mechanism according to a preferred embodiment of this application will be described in detail below.

[0027] Specifically, the adjustable massage chair mechanism includes a base 10, a pair of massage arm assemblies 20, and a kneading drive mechanism 30. The base 10 is mounted on the backrest of the main body of the massage chair, and the kneading drive mechanism 30 is mounted on the base 10. The two massage arm assemblies 20 are symmetrically distributed on both sides and are connected to the kneading drive mechanism 30. The kneading drive mechanism 30 drives the massage arm assemblies 20 to move, so that the massage arm assemblies 20 perform kneading actions.

[0028] refer to Figure 3 and Figure 4 Each massage arm assembly 20 includes a first connecting arm 21, a second connecting arm 22, and at least one self-adjusting massage assembly 23. The second connecting arm 22 is connected to the first connecting arm 21, and the first connecting arm 21 is connected to the kneading drive mechanism 30. The self-adjusting massage assembly 23 includes a rocker arm 231 and a plurality of first massage balls 232, the rocker arm 231 being rotatably mounted to the second connecting arm 22. All the first massage balls 232 are spaced apart along the height direction of the chair back, and the first massage balls 232 are rotatably mounted to the rocker arm 231.

[0029] When a user sits on the massage chair with their back against the backrest, at least one of the first massage balls 232 is pressed against the user's back. Under the pressure of the user's back, the pressed first massage ball 232 drives the swing arm 231 to rotate relative to the second connecting arm 22. This causes the swing arm 231 to move the pressed first massage ball 232 away from the user's back while the remaining first massage balls 232 move closer to the user's back. Thus, multiple first massage balls 232 can simultaneously act on the user's back, increasing the massage area and enhancing the massage effect. It is understood that different users have different body shapes. The self-adjusting massage component 23 can adjust its posture according to the user's back shape to improve the fit between the self-adjusting massage component 23 and the user's back, making the massage chair suitable for different users.

[0030] The second connecting arm 22 has a high end portion 221 and a low end portion 222 below the high end portion 221, the high end portion 221 being close to the user's shoulder and the low end portion 222 being close to the user's waist.

[0031] In one embodiment, each of the massage arm assemblies 20 includes one of the self-adjusting massage assemblies 23.

[0032] refer to Figure 1 In the first embodiment, the swing arm 231 is rotatably mounted on the high end portion 221, at which time the first massage ball 232 is close to the user's shoulder so that the first massage ball 232 can massage the user's shoulder.

[0033] refer to Figure 2 In the second embodiment, the swing arm 231 is rotatably mounted on the lower end 222, at which time the first massage ball 232 is close to the user's waist so that the first massage ball 232 can massage the user's waist.

[0034] Furthermore, each of the massage arm assemblies 20 also includes a second massage ball 24. The second massage ball 24 is rotatably mounted on the second connecting arm 22, and the second massage ball 24 and the first massage ball 232 are spaced apart to increase the massage area and improve the massage effect.

[0035] Specifically, when the self-adjusting massage component 23 is installed on the high end portion 221, the second massage ball 24 is installed on the low end portion 222. In this case, the second massage ball 24 is close to the user's waist, allowing it to massage the user's waist. When the self-adjusting massage component 23 is installed on the low end portion 222, the second massage ball 24 is installed on the high end portion 221. In this case, the second massage ball 24 is close to the user's shoulder, allowing it to massage the user's shoulder.

[0036] In another embodiment, each of the massage arm assemblies 20 includes two self-adjusting massage assemblies 23. Two swing arms 231 are rotatably mounted to the high end portion 221 and the low end portion 222 of a second connecting arm 22, respectively. The two self-adjusting massage assemblies 23 are positioned close to the user's shoulder and waist, respectively, so that the two self-adjusting massage assemblies 23 can massage the user's shoulder and waist.

[0037] Preferably, each of the self-adjusting massage components 23 is provided with two first massage balls 232, which are spaced apart along the spine and mounted on the second connecting arm 22. When the user's back is leaning against the chair back, some of the back muscles are nestled between the two first massage balls 232. Then, when the kneading drive mechanism 30 drives the massage arm assembly 20 to move, the two first massage balls 232 respectively simulate the thumb and other fingers of a human hand to simulate kneading motion, thereby achieving a realistic massage effect.

[0038] refer to Figure 3 Preferably, each of the massage arm assemblies 20 further includes a connecting shaft 25. The connecting shaft 25 is mounted on the first connecting arm 21, and the second connecting arm 22 is connected to the connecting shaft 25. The second connecting arm 22 can rotate relative to the first connecting arm 21 via the connecting shaft 25, so that the angle of the second connecting arm 22 can be adjusted.

[0039] Understandably, when a user sits on the massage chair and leans against the backrest, the first massage ball 232 or the second massage ball 24 is pressed against the user's back. The pressure on the first massage ball 232 or the second massage ball 24 causes the second connecting arm 22 to rotate, so that the second connecting arm 22 is adjusted to make all the massage balls fit against the user's back, ensuring the fit between the massage arm assembly 20 and the user's back, ensuring the massage effect, and also making the massage chair suitable for different users, improving its practicality.

[0040] It is worth mentioning that while the swing arm 231 is adjusting its angle, the second connecting arm 22 is also adjusting its angle. The two are working simultaneously to help all the massage balls quickly fit into the user's back, thereby shortening the adjustment time.

[0041] Preferably, each of the massage arm assemblies 20 further includes a reset member 26. The reset member 26 is sleeved on the connecting shaft 25, and the reset member 26 is connected to the first connecting arm 21 and the second connecting arm 22. The reset member 26 is configured to elastically deform when the second connecting arm 22 rotates, and has a tendency to drive the second connecting arm 22 back to its original position. Thus, after the user leaves the massage chair, the reset member 26 drives the second connecting arm 22 back to its original position.

[0042] As an example, the reset element 26 is implemented as a torsion spring.

[0043] refer to Figure 4 and Figure 5 In one embodiment, the kneading drive mechanism 30 includes a first rotating shaft 31, a first driving member 32, and two mounting shafts 33. The first rotating shaft 31 is rotatably mounted on the base 10. The first driving member 32 is connected to the first rotating shaft 31 and drives the first rotating shaft 31 to rotate. The two mounting shafts 33 are respectively connected to the two end faces of the first rotating shaft 31, and the axis of the first rotating shaft 31 intersects the axis of the mounting shaft 33 at an angle. The end of the first connecting arm 21 away from the second connecting arm 22 is rotatably sleeved on the mounting shaft 33. Specifically, when the first driving member 32 drives the first rotating shaft 31 to rotate, the first rotating shaft 31 drives the mounting shaft 33 to rotate, and then the mounting shaft 33 drives the first connecting arm 21 to swing back and forth, thereby achieving the kneading and massaging function.

[0044] refer to Figure 5 In one embodiment, the first driving component 32 includes a first driving motor 321, a first worm 322, and a first worm wheel 323. The first driving motor 321 is connected to the first worm 322, and the first worm wheel 323 is sleeved on the first rotating shaft 31. The first worm 322 and the first worm wheel 323 are engaged. When the first driving motor 321 drives the first worm 322 to rotate, the first worm 322 drives the first rotating shaft 31 to rotate via the first worm wheel 323.

[0045] refer to Figure 5Furthermore, the adjustable massage chair mechanism also includes a walking mechanism 40. The walking mechanism 40 includes a second rotating shaft 41, a second driving member 42, and a shifting gear 43. The second rotating shaft 41 is rotatably mounted on the base 10, and the second driving member 42 is connected to the second rotating shaft 41 to drive its rotation. The shifting gear 43 is sleeved on the second rotating shaft 41, and a rack is laid along the height direction on the backrest of the chair body, with the shifting gear 43 meshing with the rack. When the second driving member 42 drives the second rotating shaft 41 to rotate, the second rotating shaft 41 drives the shifting gear 43 to rotate, and under the constraint of the rack, the shifting gear 43 drives the entire adjustable massage chair mechanism to move up and down the backrest, thus providing a comprehensive massage to the user's entire back.

[0046] It is worth mentioning that, due to the natural curvature of the human spine, the self-adjusting massage component 23 can adjust its angle according to the curvature of each part when the adjustable massage chair mechanism moves up and down the backrest, so as to ensure that the first massage ball 232 remains in contact with the back.

[0047] In one embodiment, the second driving component 42 includes a second driving motor 421, a second worm gear 422, and a second worm wheel 423. The second driving motor 421 is connected to the second worm gear 422, and the second worm wheel 423 is sleeved on the second rotating shaft 41. The second worm gear 422 and the second worm wheel 423 are engaged. When the second driving motor 421 drives the second worm gear 422 to rotate, the second worm gear 422 drives the second rotating shaft 41 to rotate via the second worm wheel 423.

[0048] Preferably, the walking mechanism 40 further includes support wheels 44, which are rotatably mounted on both ends of the second belt shaft 41. A track is laid along the height direction on the backrest of the chair body, and the support wheels 44 are rotatably mounted on the track to improve the stability of the adjustable massage chair mechanism's up-and-down movement.

[0049] refer to Figure 4 Furthermore, the adjustable massage chair mechanism also includes a hammer-driving mechanism 50, to which the first connecting arm 21 is connected. The hammer-driving mechanism 50 drives the massage arm assembly 20 to move, so that the massage arm assembly 20 performs a hammering action.

[0050] Specifically, the hammer-driving mechanism 50 includes a third belt shaft 51, a third driving component 52, two assembly shafts 53, an eccentric wheel 54, and a connecting rod 55. The third belt shaft 51 is rotatably mounted on the base 10. The third driving component 52 is connected to the third belt shaft 51 and drives the third belt shaft 51 to rotate. The two assembly shafts 53 are eccentrically connected to the two end faces of the third belt shaft 51, and the axis of the assembly shaft 53 is parallel to the axis of the third belt shaft 51. The assembly shaft 53 is rotatably mounted on the eccentric wheel 54. The connecting rod 55 has a ball head 551, which is rotatably mounted on the first connecting arm 21. The end of the connecting rod 55 away from the first connecting arm 21 is hinged to the eccentric wheel 54. When the third belt shaft 51 is driven to rotate by the third drive component 52, the third belt shaft 51 drives the assembly shaft 53 to rotate, the assembly shaft 53 drives the eccentric wheel 54 to float, and the eccentric wheel 54 pulls the first connecting arm 21 to rotate back and forth around the first belt shaft 31 in a small amplitude through the connecting rod 55, so that the second connecting arm 22 moves back and forth, thereby achieving the massage function of hammering and tapping.

[0051] In one embodiment, the third drive component 52 includes a third drive motor 521, a belt 522, a drive pulley 523, and a driven pulley 524. The drive pulley 523 is sleeved on the output shaft of the third drive motor 521, and the driven pulley 524 is sleeved on the third belt shaft 51. The belt 522 is wound around the outer peripheral walls of the drive pulley 523 and the driven pulley 524, so that when the third drive motor 521 drives the drive pulley 523 to rotate, the drive pulley 523 drives the driven pulley 524 to rotate through the belt 522, thereby causing the third belt shaft 51 to rotate.

[0052] Those skilled in the art should understand that the embodiments of this application described above and shown in the accompanying drawings are merely examples and do not limit the scope of this application. The advantages of this application have been fully and effectively implemented. The functional and structural principles of this application have been demonstrated and explained in the embodiments, and any variations or modifications can be made to the implementation of this application without departing from the stated principles.
