[0063] like Figure 1 , Figure 2 as well as Figure 3 As shown, the present invention provides a multifunctional combined massage movement, comprising:

[0064] A frame 1 disposed on the seat frame of the massage chair moves toward the height of the user;

[0065] The massage execution part (the massage execution part is used to perform massage actions on the user), the massage execution part includes an execution bracket 2, a massage arm 3 and a knocking drive device 4, the execution bracket 2 is swingably arranged on the frame 1, the massage arm 3 includes a main arm 31 slidably arranged on the execution bracket 2 in the width direction of the user, a support arm 32 swingably arranged on the main arm 31, and a massage head 33 (the massage head 33 usually adopts a roller structure) arranged on the support arm 32, the knocking drive device 4 is arranged on the execution bracket 2 and is transmission-connected with the support arm 32, and a swinging guide rod mechanism is formed between the knocking drive device 4 and the support arm 32 to enable the support arm 32 to achieve reciprocating swinging motion relative to the main arm 31;

[0066] The multi-dimensional drive system is used to move the massage arm 3 relative to the user in at least three spatial dimensions.

[0067] In the present invention, the multi-dimensional drive system can make the massage arm 3 move relative to the user in at least three spatial dimensions (the spatial dimensions include the X-axis direction, the Y-axis direction, the Z-axis direction, the X-axis direction, the Y-axis direction and the Z-axis direction): the multi-dimensional drive system can make the frame 1 move toward the user's height, so that the massage head 33 of the massage arm 3 moves toward the user's height; the multi-dimensional drive system can make the execution bracket 2 swing on the frame 1, so that the massage head 33 of the massage arm 3 moves toward or away from the user; the multi-dimensional drive system can make the massage arm 3 move toward the user's width, so that the massage head 33 of the massage arm 3 moves toward the user's width. More importantly, the knocking drive device 4 is arranged on the execution bracket 2 and is connected to the support arm 32 in transmission, and a swing guide rod mechanism is formed between the knocking drive device 4 and the support arm 32 to enable the support arm 32 to achieve reciprocating swinging motion relative to the main arm 31, that is, the massage head 33 can achieve a knocking massage action on the user. Therefore, the multifunctional combined massage movement of the present invention can make the massage head 33 of the massage arm 3 perform various movements relative to the user, such as up and down movement, left and right movement, moving away from and approaching movement, and reciprocating swing movement, thereby realizing various massage techniques combined with the percussion massage action of the multifunctional combined massage movement, greatly improving the massage comfort of the user. In addition, the multifunctional combined massage movement has a compact structure and a high degree of integration.

[0068] The above multifunctional combined massage movement can specifically perform the following massage actions for the user:

[0069] Kneading: The first type is that the two adjacent massage arms 3 slide back and forth in the width direction of the user and in opposite directions, so that the massage heads 33 of the two massage arms 3 present an opening and closing action, clamping or releasing the user; the second type is that the two adjacent massage arms 3 slide back and forth in the width direction of the user and in opposite directions, and the massage arms 3 move up and down in the height direction of the user; the third type is that the two adjacent massage arms 3 slide back and forth in the width direction of the user and in opposite directions, and the massage arms 3 move up and down in the height direction of the user, and the massage heads 33 of the two massage arms 3 present a "circle drawing" massage action, that is, the massage head 33 of one massage arm 3 moves in a clockwise direction, and the massage head 33 of the other massage arm 3 moves in a counterclockwise direction;

[0070] Finger massage: the bracket 2 is swung relative to the frame 1, so that the massage head 33 of the massage arm 3 presses against the user;

[0071] Gua Sha: The massage arm 3 slides back and forth in the width direction of the user, or the massage arm 3 moves up and down in the height direction of the user, so that the massage head 33 of the massage arm 3 presses against the user while sliding against the user;

[0072] Tapping: The support arm 32 swings back and forth quickly relative to the main arm 31, so that the massage head 33 of the massage arm 3 continuously taps the user.

[0073] The above four massage actions can be implemented individually or in combination.

[0074] like Figure 2 , Figure 3 as well as Figure 4 As shown, in order to form a swing guide rod mechanism between the knocking drive device 4 and the support arm 32, the support arm 32 includes a support arm body 321 hinged to the main arm 31, a slide slot 322 provided in the support arm body 321, and a slider 323 slidably arranged in the slide slot 322; the knocking drive device 4 includes a knocking mounting frame 41 arranged on the execution bracket 2, an eccentric rotating shaft 42 rotatably arranged on the knocking mounting frame 41, and a knocking power mechanism 43 connected to the eccentric rotating shaft 42 in a transmission manner, and the eccentric rotating shaft 42 includes a central shaft section 421 and an eccentric shaft section 422, the central shaft section 421 rotates on the knocking mounting frame 41 in a fixed axis, and the eccentric shaft section 422 rotates and penetrates the slider 323. When the eccentric rotating shaft 42 rotates rapidly, the central shaft section 421 rotates on a fixed axis, and the eccentric shaft section 422 rotates eccentrically. Since the slider 323 is rotatably sleeved on the eccentric shaft section 422 and slidably set in the slide groove 322, the support arm body 321 reciprocates relative to the main arm 31, specifically, it is a fast and small-amplitude swinging motion, so that a knocking massage effect can be produced on the user. Regarding the specific introduction of the swing guide rod mechanism: the support arm body 321 is equivalent to the "guide rod", and the eccentric rotating shaft 42 is equivalent to the "crank", so that the support arm body 321, the slider 323, and the eccentric rotating shaft 42 together constitute a swing guide rod mechanism. Furthermore, the above-mentioned slide groove 322 extends in a straight line, and one end of the slide groove 322 faces the hinge between the support arm body 321 and the main arm 31.

[0075] As an embodiment of the above-mentioned knocking power mechanism 43: the knocking power mechanism 43 includes a knocking motor and a knocking transmission assembly (such as a pulley transmission assembly), and the knocking motor is connected to the eccentric rotating shaft 42 through the knocking transmission assembly.

[0076] like Figure 5 As shown, in order to improve the knocking massage effect, the eccentric rotating shaft 42 is divided into the first shaft section, the second shaft section, the third shaft section, the fourth shaft section and the fifth shaft section in sequence along its length direction, the third shaft section is the central shaft section 421, the second shaft section and the fourth shaft section are both eccentric shaft sections 422, and the first shaft section and the fifth shaft section are rotatably arranged on the execution bracket 2. The center lines of the first shaft section, the third shaft section and the fifth shaft section coincide with each other, the center line of the second shaft section is parallel to the center line of the third shaft section, and the center line of the fourth shaft section is parallel to the center line of the third shaft section. Furthermore, the center line of the second shaft section and the center line of the fourth shaft section are parallel to each other, so that the massage arm 3 arranged on the second shaft section and the massage arm 3 arranged on the fourth shaft section can alternately knock on the user.

[0077] In order to facilitate the assembly of the above-mentioned eccentric rotating shaft 42 to the knocking mounting frame 41, the above-mentioned knocking mounting frame 41 includes a detachably connected fixed bracket 411 and a movable bracket 412, the fixed bracket 411 is arranged on the execution bracket 2, and a bearing 413 for supporting the central shaft section 421 is sandwiched between the movable bracket 412 and the fixed bracket 411.

[0078] In order to simplify the structure of the above-mentioned execution bracket 2, the above-mentioned execution bracket 2 includes two symmetrically arranged bracket side plates 21 and multiple guide sliding shafts 22 connecting the two bracket side plates 21; the above-mentioned main arm 31 is provided with multiple sleeve holes allowing the guide sliding shafts 22 to pass through, and the sleeve holes and the guide sliding shafts 22 correspond one to one.

[0079] like Figure 4 As shown, in order to reduce the sliding resistance of the guide slide shaft 22 to the main arm 31, the guide slide shaft 22 can be composed of an optical axis. In order to further reduce the sliding resistance of the guide slide shaft 22 to the main arm 31, a sliding sleeve 34 is provided in the sleeve hole, and the sliding sleeve 34 and the guide slide shaft 22 are slidably matched.

[0080] In order to improve the compactness of the massage execution part, the knocking mounting frame 41 can be arranged in the middle of the two bracket side plates 21. When the number of the massage arms 3 is two, one massage arm 3 is located between one bracket side plate 21 and the knocking mounting frame 41, and the other massage arm 3 is located between the other bracket side plate 21 and the knocking mounting frame 41.

[0081] In order to make the massage arm 3 slide in the width direction of the user, the multi-dimensional drive system includes a transverse drive device 5, which includes a screw rod 51 that is rotatably inserted into the execution bracket 2 and a transverse power mechanism 52 that drives the screw rod 51 to rotate around a fixed axis. The screw rod 51 is threadedly inserted into the main arm 31, and both ends of the screw rod 51 are rotatably set on the frame 1. When the screw rod 51 rotates, the main arm 31 slides along the length direction of the guide shaft 22 due to the threaded fitting relationship between the main arm 31 and the screw rod 51, and the sliding fitting relationship between the main arm 31 and the execution bracket 2. Further, the transverse power mechanism 52 includes a transverse motor and a transverse transmission assembly (such as a pulley transmission assembly). The transverse motor is arranged on the frame 1, and the transverse motor is connected to one end of the screw rod 51 through the transverse transmission assembly.

[0082] like Figure 2 and Figure 3 As shown, in order to enable the two adjacent massage arms 3 to perform an opening and closing action, the screw rod 51 has a first thread segment and a second thread segment with opposite thread directions; there are two massage arms 3, wherein the main arm 31 of one massage arm 3 is threadedly engaged with the first thread segment, and the main arm 31 of the other massage arm 3 is threadedly engaged with the second thread segment. When the screw rod 51 rotates, the two massage arms 3 slide back to back or toward each other, thereby performing a kneading massage action on the user.

[0083] In order to make the above-mentioned execution bracket 2 swing within a certain angle range relative to the frame 1, the above-mentioned multi-dimensional drive system includes a radial drive device 6, which includes a swing drive shaft 61 rotatably arranged on the frame 1, a swing power mechanism 62 that drives the swing drive shaft 61 to rotate around a fixed axis, a driving gear 63 fixedly sleeved on the swing drive shaft 61, and a driven rack 64 integrally formed on the execution bracket 2, the driven rack 64 is meshed with the driving gear 63, the driven rack 64 is arc-shaped and the corresponding circle center coincides with the swing center line of the execution bracket 2. Further, the number of the driving gear 63 and the driven rack 64 are both two and correspond to each other, and the two driven racks 64 are symmetrically arranged on the opposite sides of the execution bracket 2 and do not misalign with each other, so that the opposite sides of the execution bracket 2 can be ensured to rotate synchronously.

[0084] The above-mentioned swing power mechanism 62 includes a swing motor, a swing transmission assembly (such as a pulley transmission assembly), and a swing gearbox. The swing motor and the swing gearbox are both fixed to the frame 1. The swing motor is connected to the swing gearbox through the swing transmission assembly, and the swing drive shaft 61 is connected to the swing gearbox.

[0085] In order to make the massage arm 3 move toward the height of the user, the multi-dimensional drive system includes a travel drive device 7, which includes a travel driving shaft 71 rotatably arranged on the frame 1, a travel power mechanism 72 driving the travel driving shaft 71 to rotate along a fixed axis, and a travel wheel 73 fixedly sleeved on the travel driving shaft 71. The travel power mechanism 72 includes a travel motor and a travel gearbox, and the travel motor drives the travel driving shaft 71 to rotate after the travel gearbox changes speed.

[0086] Furthermore, the massage chair seat frame is provided with a rack track, which extends from the top of the massage chair seat frame to the bottom of the massage chair seat frame. The travel wheel 73 is a gear structure and meshes with the rack track. Under the action of the travel power mechanism 72, the frame 1 moves along the extension direction of the rack track, thereby realizing the massage arm 3 of the massage execution part moving up and down toward the user's height direction.

[0087] In order to improve the compactness of the multifunctional combined massage movement, the frame 1 includes two frame side panels 11 and an intermediate connecting plate 12 connecting the two frame side panels 11. The intermediate connecting plate 12 is provided with an escape notch 121 for the massage arm 3 to move. The escape notch 121 is provided to avoid motion interference between the massage arm 3 and the frame 1.

[0088] In summary, the multifunctional combined massage core of the present invention has a compact structure and high integration, and can realize a variety of massage techniques that can be combined with tapping massage actions, greatly improving the massage comfort of the user. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.

[0089] 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 familiar with 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 a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
