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 folding massage mechanism according to a preferred embodiment of this application will be described in detail below.

[0027] Specifically, the folding massage mechanism includes a base 10, a pair of massage arm mechanisms 20, a kneading drive mechanism 30, and a folding drive mechanism 40.

[0028] 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. Two massage arm mechanisms 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 mechanisms 20 to move, so that the massage arm mechanisms 20 perform kneading actions.

[0029] refer to Figure 1Each of the massage arm mechanisms 20 includes an arm assembly 21 and a massage wheel 22. The arm assembly 21 includes a first movable arm 211, one end of which is pivotally connected to the kneading drive mechanism 30, and the other end of which is equipped with a massage wheel 22. The kneading drive mechanism 30 drives the massage wheel 22 to act on the user's back through the arm assembly 21.

[0030] It is worth mentioning that the first movable arm 211 is connected to the folding drive mechanism 40, which is used to drive the first movable arm 211 to rotate, so that the end of the first movable arm 211 on which the massage roller 22 is mounted is close to or away from the user's back.

[0031] Specifically, the folding drive mechanism 40 includes a conveyor component 41, two sets of assembly components 42, and two sets of connecting components 43, wherein the conveyor component 41 is mounted on the base 10. Each set of assembly components 42 includes a first mounting part 421, and each set of connecting components 43 includes a first connector 431. Each first connector 431 is rotatably mounted at both ends to a first mounting part 421 and a first movable arm 211, respectively, and the first mounting part 421 is connected to the conveyor component 41. The conveyor component 41 drives the first mounting part 421 to move so that the first mounting part 421 pulls the first movable arm 211 to rotate via the first connector 431.

[0032] It is worth mentioning that both ends of the first connector 431 are formed into ball heads. The ball heads at both ends of the first connector 431 are rotatably mounted on the first assembly 421 and the first movable arm 211, respectively, so that the first connector 431 can rotate in any direction relative to the first assembly 421 and the first movable arm 211.

[0033] refer to Figures 2 to 5 Furthermore, the arm assembly 21 also includes a second movable arm 212. One end of the second movable arm 212 is pivotally connected to the kneading drive mechanism 30; the other end of each of the second movable arms 212 is equipped with a massage roller 22. In this way, the kneading drive mechanism 30 can drive four massage rollers 22 to act on the user's back simultaneously through the two arm assemblies 21, increasing the massage area and improving the comfort of the massage chair.

[0034] It is worth mentioning that the second movable arm 212 is connected to the folding drive mechanism 40, which is used to drive the first movable arm 211 and the second movable arm 212 included in each of the two sets of arm assemblies 21 to rotate in opposite or the same direction.

[0035] Each of the massage arm mechanisms 20 has a working state and a retracted state. The folding drive mechanism 40 drives the first movable arm 211 and the second movable arm 212 to rotate, so that the massage arm mechanism 20 switches between the working state and the retracted state.

[0036] When the folding drive mechanism 40 drives the first movable arm 211 and the second movable arm 212 to rotate so that the end of the first movable arm 211 that is equipped with the massage roller 22 and the end of the second movable arm 212 that is equipped with the massage roller 22 are simultaneously moved away from the user's back, the massage arm mechanism 20 switches to the storage state. This prevents the massage roller 22 from pushing against the user, improves the flatness of the chair back, and thus ensures the comfort of the massage chair.

[0037] When the folding drive mechanism 40 drives the first movable arm 211 and the second movable arm 212 to rotate so that one end of the first movable arm 211 and the other end of the second movable arm 212 that are mounted on the massage roller 22 are simultaneously close to the user's back, the massage arm mechanism 20 switches to the working state so that the massage roller 22 acts on the user's back to massage the user's back.

[0038] In one embodiment, when the folding drive mechanism 40 drives the first movable arm 211 and the second movable arm 212 to rotate in opposite directions, the massage arm mechanism 20 switches to the storage state; when the folding drive mechanism 40 drives the first movable arm 211 and the second movable arm 212 to rotate in opposite directions, the massage arm mechanism 20 switches to the working state.

[0039] As deformable, the folding drive mechanism 40 drives the first movable arm 211 and the second movable arm 212 to rotate in the same direction, so that the massage arm mechanism 20 switches between the stored state and the working state. Further, each assembly assembly 42 includes a second fitting 422, and the connecting assembly 43 includes a second connector 432. Each second connector 432 is rotatably mounted at both ends to a second fitting 422 and a second movable arm 212, respectively. The conveying member 41 drives the first fitting 421 and the second fitting 422 to move, such that the first fitting 421 and the second fitting 422 pull the first movable arm 211 and the second movable arm 212 to rotate via the first connector 431 and the second connector 432, respectively.

[0040] In one embodiment, the moving member 41 is implemented as a cylinder.

[0041] Preferably, the base 10 forms a guide structure 11, the extension direction of which is parallel to the distribution direction of the first assembly 421 and the second assembly 422 included in the assembly assembly 42. Both the first assembly 421 and the second assembly 422 are slidably mounted on the guide structure 11, which defines the direction of movement of the first assembly 421 and the second assembly 422.

[0042] As an example, the guide structure 11 is implemented as a guide rail or a guide rod.

[0043] refer to Figure 2 and Figure 5 In one embodiment, the conveyor component 41 includes a first motor 411 and a first lead screw 412, wherein the first lead screw 412 is rotatably mounted on the base 10 and connected to the first motor 411. The first lead screw 412 has two conveyor portions 4121, and the outer peripheral wall of each conveyor portion 4121 forms an external thread. A first fitting 421 and a second fitting 422 are respectively threaded onto the two conveyor portions 4121. When the first motor 411 drives the first lead screw 412 to rotate, the first fitting 421 and the second fitting 422 move along the extension direction of the guide structure 11, causing the first movable arm 211 and the second movable arm 212 to rotate.

[0044] refer to Figure 3 and Figure 5 In another embodiment, the conveying member 41 includes two first motors 411A and two first lead screws 412A, wherein both first lead screws 412A are rotatably mounted on the base 10, and one first lead screw 412A is connected to one first motor 411A. Each first lead screw 412A has a conveying portion 4121A, the outer peripheral wall of which is formed with an external thread. Two first fittings 421A are threaded onto one first lead screw 412A, and two second fittings 422A are threaded onto the other first lead screw 412A. When the two first motors 411A simultaneously drive the two first lead screws 412A to rotate, causing the first fitting 421A and the second fitting 422A to move along the guide structure 11, the first movable arm 211 and the second movable arm 212 rotate.

[0045] In the two embodiments described above, preferably, two adjacent first assemblies 421 are integrally formed, and two adjacent second assemblies 422 are integrally formed.

[0046] refer to Figure 4 and Figure 5In a modified embodiment, the conveyor component 41 includes four first motors 411B and four first lead screws 412B, wherein each of the first lead screws 412B is rotatably mounted on the base 10, and the four first lead screws 412B are respectively connected to the four first motors 411B. Each first lead screw 412B has a conveyor portion 4121B, the outer peripheral wall of which is formed with an external thread. Each conveyor portion 4121B is threaded with a first fitting 421 or a second fitting 422. When each first motor 411B drives the corresponding first lead screw 412B to rotate, causing the first fitting 421 and the second fitting 422 to move along the guide structure 11, the first movable arm 211 and the second movable arm 212 rotate in any direction.

[0047] When a single first motor 411B drives the corresponding first lead screw 412B to rotate in both directions to move the first assembly 421 or the second assembly 422 along the extension direction of the guide structure 11, the first assembly 421 pulls the first movable arm 211 to rotate in any direction via the first connector 431, and the second assembly 422 pulls the second movable arm 212 to rotate in any direction via the second connector 432. In this embodiment, the two first movable arms 211 and the two second movable arms 212 are controlled by four first motors 411B respectively. For example, the first movable arm 211 on one side rotates in the opposite direction to the second movable arm 212 on the same side, and the first movable arm 211 on the other side rotates in the same direction as the second movable arm 212 on the same side; or, the two first movable arms 211 and the two second movable parts 212 rotate in the same direction. The above are only examples and do not limit the specific movement direction of the first movable arm 211 and the second movable arm 212. All of these can achieve the function of tapping massage while switching the state of the massage arm mechanism 20.

[0048] refer to Figure 1 and Figure 2In one embodiment, the kneading drive mechanism 30 includes a rotating shaft 31, a driving member 32, and two mounting shafts 33. The rotating shaft 31 is rotatably mounted on the base 10. The driving member 32 is connected to the rotating shaft 31 and drives the rotating shaft 31 to rotate. The two mounting shafts 33 are respectively sleeved on both ends of the rotating shaft 31, and the axis of the rotating shaft 31 intersects the axis of the mounting shaft 33 at an angle. A first movable arm 211 and a second movable arm 212 are each rotatably sleeved on a mounting shaft 33 at an end away from the massage roller 22. Specifically, when the driving member 32 drives the rotating shaft 31 to rotate, the rotating shaft 31 drives the mounting shaft 33 to rotate, and then the mounting shaft 33 drives the first movable arm 211 and the second movable arm 212 to swing back and forth simultaneously, thereby achieving the kneading and kneading massage function.

[0049] refer to Figure 4 In another embodiment, the kneading drive mechanism 30 includes a second motor 31A and a second lead screw 32A. The second lead screw 32A is rotatably mounted on the base 10 and connected to the second motor 31A. When the second lead screw 32A is driven to rotate by the second motor 31A, the two sets of massage arm mechanisms 20 move in the left-right direction under the constraints of the connecting assembly 42, the assembly assembly 43, and the first guide structure 11, so that the two sets of massage arm mechanisms 20 distributed on the left and right can move in the left-right direction, thereby allowing the massage arm mechanisms 20 to massage different parts of the user's back on the left and right sides.

[0050] It is worth mentioning that both ends of the second connector 432 are formed into ball heads, and the two ball heads are respectively connected to the second assembly 422 and the second movable arm 212, so that the second connector 432 can rotate in any direction relative to the second assembly 422 and the second movable arm 212.

[0051] refer to Figure 4Furthermore, the folding massage mechanism also includes a walking mechanism 60. The walking mechanism 60 includes a connecting shaft 61, a second driving member 62, and a shifting gear 63. The connecting shaft 61 is rotatably mounted on the base 10, and the second driving member 62 is connected to the connecting shaft 61 to drive its rotation. The shifting gear 63 is sleeved on the connecting shaft 61, and a rack is laid along the height direction on the backrest of the chair body, with the shifting gear 63 meshing with the rack. When the second driving member 62 drives the connecting shaft 61 to rotate, the connecting shaft 61 drives the shifting gear 63 to rotate, and under the constraint of the rack, the shifting gear 63 drives the entire folding massage mechanism to move up and down the backrest, thus providing a comprehensive massage to the user's entire back.

[0052] As an example, the second driving member 62 is implemented to include a motor.
