[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Embodiment 1:

[0027] See also Figure 1 A dual-mode multi-massage head swing back massage device comprises a mounting frame 1, on which a driving member 2 is fixedly mounted, the driving member 2 comprises a massage motor 22 fixedly mounted on the mounting frame 1, the output end of the massage motor 22 is transmission-connected to two eccentric wheels 24, a back massage member 3 is also mounted on the mounting frame 1, the back massage member 3 comprises a first connecting rod 31 rotatably connected to the eccentric wheel 24, and a plurality of back massage balls 32 are arranged on the first connecting rod 31; a head massage member 5 is also mounted on the mounting frame 1, the head massage member 5 comprises a second connecting rod 51 rotatably connected to the eccentric wheel 24, a limiting shaft 52 is also fixedly mounted on the top of the mounting frame 1, the limiting shaft 52 is rotatably connected to a rotating seat 53, two ends of the second connecting rod 51 are rotatably connected to the eccentric wheel 24 and the rotating seat 53 respectively, a mounting seat 54 is fixedly mounted on the upper surface of the top end of the second connecting rod 51, and a plurality of head massage balls 55 are mounted on the mounting seat 54.

[0028] See also Figure 2-Figure 4 The driving member 2 includes a mounting box body 21 fixedly mounted on the mounting frame 1, the massage motor 22 is fixedly connected to the mounting box body 21, the mounting box body 21 is provided with two transmission shafts 23, the transmission shaft 23 is transmission-connected to the output end of the massage motor 22, the transmission shaft 23 is transmission-connected to the eccentric wheel 24, and the eccentric wheel 24 is rotationally connected to the first connecting rod 31 and the second connecting rod 51.

[0029] Among them, the mounting frame 1 is a rectangular frame, the mounting frame 1 is used to install various devices in the chair back, the driving component 2 is used to drive the massage device, the two sides of the mounting box body 21 are fixedly connected to the two rods of the mounting frame 1, the massage motor 22 is fixedly installed in the middle part of the mounting box body 21, and the output shaft of the massage motor 22 is inserted into the mounting box body 21. Transmission shafts 23 are provided on both sides of the mounting box body 21. The massage motor 22 can drive the two transmission shafts 23 to rotate, and the transmission shaft 23 can drive the eccentric wheel 24 to rotate.

[0030] See also Figure 2 The top end of the first connecting rod 31 of the back massage part 3 is rotatably installed on the top end of the eccentric wheel 24. When the eccentric wheel 24 rotates, it can drive the first connecting rod 31 to reciprocate up and down. When the first connecting rod 31 moves, it drives the back massage ball 32 to move, so that the back of the customer sitting on the massage chair can be massaged.

[0031] See also Figure 3-Figure 4 The bottom end of the second connecting rod 51 of the head massage part 5 is also rotatably connected to the eccentric wheel 24. When the eccentric wheel 24 rotates, the second connecting rod 51 is driven to reciprocate up and down. By setting a limiting shaft 52 on the top of the mounting frame 1, the limiting shaft 52 is rotatably connected to the rotating seat 53, and the second connecting rod 51 is rotatably connected to the rotating seat 53. When the second connecting rod 51 reciprocates up and down, the second connecting rod 51 will drive the rotating seat 53 to swing back and forth in the fan surface. At this time, the limiting shaft 52 and the rotating seat 53 play a role in limiting the top end of the second connecting rod 51. When the second connecting rod 51 moves, it drives the head massage ball 55 to reciprocate to massage the customer's head.

[0032] Operation process: When the customer sits on the massage chair and starts massage, the driving motor 72 starts, and drives the two transmission shafts 23 to rotate in the installation box 21. The transmission method can be various methods such as gears and connecting rods, as long as the two eccentric wheels 24 can be driven by the massage motor 22 at the same time. When the massage motor 22 drives the two eccentric wheels 24, the rotation speed of the two eccentric wheels 24 is the same, but the starting position of the rotation can be different. When the eccentric wheel 24 rotates, it drives the first connecting rod 31 to move. The top center point of the first connecting rod 31 rotates coaxially with the eccentric wheel 24, so that the first connecting rod 31 reciprocates up and down as a whole. Due to the action of the eccentric wheel 24, the first connecting rod 31 will also rotate to both sides to a certain extent while reciprocating up and down, so that the back massage ball 32 can be used to perform a large-scale massage on the customer's back;

[0033] While the first connecting rod 31 moves, since the two ends of the second connecting rod 51 are rotatably connected to the eccentric wheel 24 and the rotating seat 53 respectively, the second connecting rod 51 is driven to synchronously perform up and down reciprocating motion and rotational motion to both sides. The up and down motion of the second connecting rod 51 is the same as that of the first connecting rod 31, but the rotation direction is opposite. Each massage ball is rotatably connected to the mounting seat 54, and the mounting seat 54 is perpendicular to the rotating seat 53. When the second connecting rod 51 moves, it drives each mounting seat 54 to move, and the customer's shoulder and neck are massaged through each head massage ball 55.

[0034] Embodiment 2:

[0035] See also Figure 3 and Figure 4 This embodiment provides a technical solution based on the first embodiment: it also includes a waist massage part 4, the waist massage part 4 includes a rotating shaft 41 arranged at the bottom of the mounting frame 1, the rotating shaft 41 is rotatably connected to a rotating main rod 42, one end of the rotating main rod 42 is rotatably connected to a movable connecting rod 43, and a waist massage ball 44 is arranged at the top of the movable connecting rod 43.

[0036] The rotating shaft 41 is arranged on the back side of the mounting frame 1, and a space is reserved around the rotating shaft 41 for the rotating main rod 42 to rotate. The rotating main rod 42 rotates around the rotating shaft 41, and the rotating main rod 42 swings left and right. The movable connecting rod 43 is rotatably connected to the end of the rotating main rod 42 away from the rotating shaft 41. The movable connecting rod 43 can swing up and down, and the movable connecting rod 43 rotates around the bottom end of the rotating main rod 42. The rotating shaft 41 line of the movable connecting rod 43 and the rotating shaft 41 line of the rotating main rod 42 are perpendicular to each other. The waist massage ball 44 is a cylindrical shape with a narrow middle and protruding at both ends. The waist massage ball 44 is rotatably connected to the end of the movable connecting rod 43 away from the rotating main rod 42.

[0037] See also Figure 3 The back massage part 3 also includes a limit rod 33 arranged at the bottom of the mounting frame 1, a limit slide groove 34 is provided at the bottom end of the first connecting rod 31, and the waist massage part 4 also includes a connecting hole 45 provided on the movable connecting rod 43, and a clamping head 46 is fixedly connected to the bottom end of the first connecting rod 31, and the clamping head 46 is adapted to the movable connecting rod 43 and is rotatably connected.

[0038] The limiting rod 33 is arranged on the front surface of the mounting frame 1, and the center of the limiting rod 33 is on the same straight line as the axis of the eccentric wheel 24, and the straight line is parallel to the two side edges of the mounting frame 1. The limiting slide groove 34 is slidably matched with the limiting rod 33, and the clamping head 46 of the first connecting rod 31 clamps the two sides of the movable connecting rod 43, and the center of the clamping head 46 is provided with a matching connecting hole 45.

[0039] Working principle: When in use, when the first connecting rod 31 moves up and down, since the connection between the top end of the first connecting rod 31 and the eccentric wheel 24 is not located at the axis of the eccentric wheel 24, the first connecting rod 31 is displaced to shake left and right. At this time, since the limit rod 33 is restricted from moving left and right by the limit slide groove 34 of the first connecting rod 31, the limit rod 33 becomes the second rotation center of the first connecting rod 31. When the first connecting rod 31 descends, the clamping head 46 of the first connecting rod 31 pushes the movable connecting rod 43 downward. At this time, the end of the movable connecting rod 43 away from the rotating main rod 42 rotates downward. At the same time, due to the action of the eccentric wheel 24, the first connecting rod 31 will rotate, and the clamping head 46 drives the movable connecting rod 43 to rotate together. The movable connecting rod 43 rotates by rotating the main rod 42, so that the waist massage ball 44 can pitch back and forth and rotate left and right to massage the waist.

[0040] Embodiment three:

[0041] The existing massage chairs still have the problem that when the customer is small or does not fit closely to the back of the chair, the massage structure of the shoulder and neck area cannot massage well. Figure 3 and Figure 4 This embodiment provides a technical solution based on the first embodiment: the mounting frame 1 is divided into a lower frame and an upper frame, the lower frame and the upper frame are rotatably connected via a fixing member 6, the fixing member 6 includes a main hinge seat 61 arranged at the top end of the lower frame, and a secondary hinge seat 62 at the bottom end of the upper frame, and the second connecting rod 51 is also divided into a lower rod body and an upper rod body, and the lower rod body and the upper rod body are rotatably connected.

[0042] The mounting frame 1 is divided into two parts, and the separated lower frame is fixed in the chair back, with the separation point being located at the customer's shoulder and neck. The separated frames are connected by setting a fixing part 6, and the main hinge seat 61 and the auxiliary hinge seat 62 are set to enable the upper frame to be adjusted in pitch relative to the lower frame.

[0043] A support rod 63 is fixedly connected to the top of the lower frame, a fixed plate 64 is fixedly connected to the top of the support rod 63, a rotating sleeve 65 and a driving sprocket 66 are rotatably connected to the fixed plate 64, a transmission sprocket 68 is provided on the side surface of the rotating sleeve 65, and a transmission chain 67 is connected to the driving sprocket 66 and the transmission sprocket 68.

[0044] The support rod 63 connects and fixes the fixed plate 64 to the lower frame. The support rod 63 supports the fixed plate 64 obliquely upward. The fixed plate 64 is located at the rear of the upper frame and is used to limit the movement range of the upper frame. The driving sprocket 66 is rotatably connected to the top center position of the fixed plate 64. Two rotating sleeves 65 are symmetrically arranged about the driving sprocket 66. The transmission chain 67 is connected to each sprocket at the same time. When the driving sprocket 66 rotates, the transmission chain 67 drives each transmission sprocket 68 to rotate at the same time.

[0045] Reference Figure 5 A power member 7 and an adjusting member 8 are also installed on the fixing member 6. The power member 7 includes a mounting bracket 71 fixedly installed on the fixing plate 64. A driving motor 72 is fixedly installed on the mounting bracket 71. The output end of the driving motor 72 is transmission-connected with a driving bevel gear 73. One end of the driving sprocket 66 is fixedly connected with a driving bevel gear 74. The driving bevel gear 73 is meshed with the driving bevel gear 74.

[0046] The power member 7 is used to provide the power required for the rotation of the drive sprocket 66, the adjustment member 8 is used to adjust the front and rear pitch of the upper frame, the mounting bracket 71 is used to install the drive motor 72, and the transmission bevel gear 74 is fixedly connected to the top of the drive sprocket 66. The drive motor 72 drives the drive bevel gear 73 to rotate by controlling the rotation of the transmission bevel gear 74, and the drive bevel gear 73 then drives the drive sprocket 66 to rotate.

[0047] Reference Figure 6 The adjusting member 8 includes an adjusting threaded rod 81 threadedly connected to the inner wall of the rotating sleeve 65, the top of the adjusting threaded rod 81 passes through the fixed plate 64, the top of the adjusting threaded rod 81 is fixedly connected to a movable head 82, and a connecting seat 83 is fixedly installed on the back of the upper frame, and the movable head 82 is rotatably connected to the connecting seat 83.

[0048] The outer wall of the adjusting threaded rod 81 is provided with a thread, and the inner wall of the rotating sleeve 65 is provided with a thread corresponding to the adjusting threaded rod 81. After the movable head 82 at the top of the adjusting threaded rod 81 is rotatably connected with the connecting seat 83, the connecting seat 83 is fixed to the back of the upper frame, thereby fixing the rotation direction of the adjusting threaded rod 81, so that the adjusting threaded rod 81 can only move forward and backward along the axial direction of the rotating sleeve 65 without rotating.

[0049] Working principle: When in use, the driving motor 72 is driven, and the driving motor 72 drives the driving sprocket 66 to rotate through the driving bevel gear 73 and the transmission bevel gear 74. The driving sprocket 66 drives the rotating sleeve 65 to rotate through the transmission chain 67 and the transmission sprocket 68. When the rotating sleeve 65 rotates, the adjusting threaded rod 81 is pushed forward. Since the movable head 82 is rotatably connected with the connecting seat 83, the connecting seat 83 drives the upper frame to lean forward, and then drives the second connecting rod 51 to lean forward. At this time, the head massage ball 55 also leans forward, so that when the customer is short or not close to the chair back, the head massage ball 55 can be close to the customer's shoulder and neck.

[0050] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
