[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention.

[0026] For combination Figure 1 In the first embodiment of the present application, the massage movement includes: a frame A, a massage mechanism B, a width driving mechanism C, a strong and weak driving mechanism D, and a limit mechanism E.

[0027] The frame A has a pair of support frames A1 arranged opposite to each other on the left and right sides and a base frame A2 located between the two support frames A1. The massage mechanism B includes: a first massage head B1, a massage arm B2, and a first nut member B3. The width drive mechanism C includes: a width drive shaft support C1 extending left and right and two guide wheels C2 located on both sides of the width drive shaft support C1. The width drive mechanism C controls the massage mechanism B to move in the left and right directions, and the strong and weak drive mechanism D controls the front and rear ejection positions of the massage mechanism B. A pair of support frames A1 are respectively provided with a clearance space for configuring the guide wheel C2, and the clearance space is roughly in the shape of a long strip extending in the up and down direction, so that the width drive shaft support C1 is configured to be movable up and down relative to the frame A. A first nut member B3 is arranged between the massage arm B2 and the width drive shaft support C1, and the outer periphery of the width drive shaft support C1 has a first male thread, and the first nut member B3 has a first female thread (not shown) that matches the first male thread. The limit mechanism E allows the massage arm B2 to move left and right and limits the massage arm B2 from rotating with the width drive shaft support C1. Specifically, the limit mechanism E includes: a limit shaft support E1 extending left and right and arranged between a pair of support frames A1 and a transmission member E2. The transmission member E2 has a first end hinged to the limit shaft support E1 and a second end hinged to the massage arm B2, and the first end can move along the axial direction of the limit shaft support E1. The rotation axis of the first end relative to the limit shaft support E1 and the rotation axis of the second end relative to the massage arm B2 are parallel. When the width drive shaft support C1 rotates, it drives the massage arm B2 to move in the left and right directions through the first nut member B3. The active position of the massage mechanism B is controlled by controlling the forward and reverse rotation of the width drive shaft support C1. The strong and weak drive mechanism D includes: a strong and weak drive shaft support D1 extending up and down, a second nut member D2, and a strong and weak drive motor D3 configured on the base frame A2 to drive the strong and weak drive shaft support D1 to rotate. The outer periphery of the strong and weak drive shaft support D1 has a second male thread, and the second nut member D2 has a second female thread (not shown) that matches the second male thread. The second nut member D2 is sleeved on the strong and weak drive shaft support D1, and has a second female thread that matches the second male thread. The second nut member D2 is connected to the width drive mechanism C by being sleeved on the width drive shaft support C1, and then the strong and weak drive shaft support D1 rotates to drive the width drive mechanism C to move in the up and down directions. A bearing member (not shown) can be arranged between the second nut member D2 and the width drive shaft support C1.

[0028] Through the above design, when the first massage head B1 is subjected to the force of the user, the force is transmitted to the width drive shaft support C1, the strong and weak drive shaft support D1 and the limit shaft support E1. The width drive shaft support C1 and the limit shaft support E1 extend left and right, while the strong and weak drive shaft support D1 extends up and down. The force exerted by the user on the first massage head B1 is dispersed on different cross-configured shaft supports.

[0029] It should be noted that the specific manner in which the width driving shaft support C1 is configured to be movable up and down relative to the frame A is not limited to Figure 1 Other ways to make the width drive shaft support C1 rotatable and restricted to move up and down can also be replaced. It should be noted that the specific structure of the limiting mechanism E is not limited to Figure 1 In another embodiment, for example, the transmission member E2 can be omitted, and the limit shaft support E1 can pass through the massage arm B2. At the same time, the limit shaft support E1 is closer to the front and rear direction relative to the width drive shaft support C1. This method can also make the width drive shaft support C1 drive the first massage head B1 to swing forward when it rises, and drive the first massage head B1 to swing backward when it falls. It should also be noted that the specific configuration of the strong and weak drive motor D3 is not limited to being configured on the base frame A2. In one embodiment, the strong and weak drive motor D3 can also be set on the support frame A1, and drive the strong and weak drive shaft support D1 to rotate through a gear transmission component or other transmission components. It should also be noted that the limit shaft support E1 is also an eccentric shaft support, and when it rotates, it can drive the first massage head B1 to perform a tapping massage action through the transmission member E2.

[0030] Combination Figures 2 to 9 In the second embodiment of the present application, the massage movement includes: a frame 1, a pair of massage mechanisms 2, a width drive mechanism 3, a strong and weak drive mechanism 4, a knocking drive mechanism 5, a walking drive mechanism 6, a left and right position detection mechanism 7, an up and down position detection mechanism 8, and a walking position detection mechanism 9. For the convenience of illustration, the control mechanism of the massage movement is omitted in the figure of the second embodiment, which can be configured on the frame 1. The massage mechanism 2 includes a first massage head 12 and a second massage head 13. The width drive mechanism 3 is used to control the pair of massage mechanisms 2 to move relatively close and away along the left and right direction X, so as to massage the user's back in the width direction. The strong and weak drive mechanism 4 is used to control the pair of massage mechanisms 2 to move along the front and back direction Y, so as to adjust the ejection amount of the pair of massage mechanisms 2, and then adjust the pressure on the user's back. Please refer to Figure 7 Understand. The knocking drive mechanism 5 is used to drive a pair of first massage heads 12 of the massage mechanism 2 to alternately knock on the user's back. The travel drive mechanism 6 is used to drive the massage movement as a whole to move along the guide rail frame when the massage movement is configured on the guide rail frame. The left and right position detection mechanism 7 is used to assist in detecting the active position of the massage mechanism 2 along the left and right directions. The upper and lower position detection mechanism 8 is used to assist in detecting the ejection amount of the massage mechanism 2 along the front and rear direction Y. The travel position detection mechanism 9 is used to assist in detecting the position of the massage movement relative to the guide rail frame when the massage movement is configured on the guide rail frame. The control mechanism controls the operation of the aforementioned mechanisms. The specific structure of the massage movement of the first embodiment will be further described in detail below.

[0031] For rack 1, combine Figures 2 to 4The frame 1 includes: a first support frame 1A, a second support frame 1B, and a bottom frame 1C. The first support frame 1A and the second support frame 1B are arranged opposite to each other on the left and right sides, and the bottom frame 1C is arranged on the lower side between the first support frame 1A and the second support frame 1B. The left and right sides of the bottom frame 1C can be fixed to the first support frame 1A and the second support frame 1B by fasteners. Figure 5 The first support frame 1A and the second support frame 1B are respectively provided with a clearance space S extending along the up-down direction Z, and the clearance spaces S of the first support frame 1A and the second support frame 1B are arranged opposite to each other. The clearance space S includes a first walking space S1 located on the outside along the left-right direction X and a second walking space S2 located on the inside, and the second walking space S2 is closer to the massage mechanism 2 relative to the first walking space S1. The second walking space S2 of each support frame is provided with a rack portion 1D extending up and down, and the rack portions 1D on a pair of support frames are arranged opposite to each other left and right. The clearance space S is used for the width driving mechanism 3 to move up and down, and its function will be explained in conjunction with the width driving mechanism 3.

[0032] For massage institution 2, combined Fig. 9 and Fig.10 Each massage mechanism 2 comprises: a massage arm 11, a first massage head 12, a second massage head 13, a knocking connection part 14 located on the massage arm 11, two sleeves 16, two second bearings 17, a first nut 18 and a first elastic part 19. The first nut 18 is sleeved on the width drive shaft support 3A and has a first female thread that matches the first male thread on the outer periphery of the width drive shaft support 3A. The two sleeves 16 are sleeved on the width drive shaft support 3A and are arranged on both sides of the first nut 18. The two second bearings 17 are sleeved on the two sleeves 16 respectively. The massage arm 11 has a sleeve connection part 15 sleeved on the two second bearings 17. In the above manner, the massage mechanism 2 can swing back and forth as a whole, thereby adjusting the protrusion of the first massage head 12. The massage movement rotates through the width drive shaft support 3A while the first nut 18 does not rotate, so that the massage mechanism 2 moves along the axial direction of the width drive shaft support 3A.

[0033] For the width drive mechanism 3, combined Figure 5 and Figure 6, which includes: a width driving shaft support 3A, a width driving motor, an auxiliary shaft support 3C, a first connecting member 3D, and a second connecting member 3E. The left and right sides of the width driving shaft support 3A are respectively arranged in the first walking space S1 of the first support frame 1A and the second support frame 1B through the first bearing member 3F, and the left and right sides of the auxiliary shaft support 3C are respectively engaged with the rack part 1D on a pair of support frames through the gear member 3G. The first connecting member 3D rotatably supports the right ends of both the width driving shaft support 3A and the auxiliary shaft support 3C, and the second connecting member 3E rotatably supports the left ends of both the width driving shaft support 3A and the auxiliary shaft support 3C. The width driving motor 3B is arranged on the first connecting member 3D to drive the width driving shaft support 3A to rotate, but it is easy to understand that in another embodiment, the width driving motor 3B can be arranged on the second connecting member 3E. The rotation axes of the width driving shaft support 3A and the auxiliary shaft support 3C are parallel, both extend left and right, and the two move up and down synchronously. The massage mechanism 2 is supported on the width drive shaft support 3A so as to swing forward and backward. The width drive shaft support 3A and the auxiliary shaft support 3C can rotatably pass through the second nut member 4B (supported on the second nut member 4B through a bearing), so that the width drive mechanism 3 and the second nut member 4B are connected. However, it is easy to understand that in another embodiment, only one of the width drive shaft support 3A and the auxiliary shaft support 3C can pass through the second nut member 4B. This method can also drive the width drive mechanism 3 as a whole to move up and down when the second nut member 4B moves up and down. Through the cooperation of the auxiliary shaft support 3C, the gear member 3G and the rack part 1D, the massage mechanism 2 can be ejected without deflection. The width drive shaft support 3A includes two sections of first male threads. In order to make the two massage mechanisms 2 approach and move away from each other, the thread structures of the first male threads on the outer periphery of the left and right sides of the width drive shaft support 3A are opposite, so that when the width drive shaft support 3A rotates forward or reversely, the two massage mechanisms 2 can be correspondingly approached or moved away from each other.

[0034] For strong and weak drive mechanism 4, combined Figure 3 , which includes a strong and weak drive shaft support 4A, a second nut component 4B, and a strong and weak drive motor 4C. The strong and weak drive shaft support 4A and the strong and weak drive motor 4C constitute a lifting drive component that drives the second nut component 4B to move up and down. The strong and weak drive shaft support 4A extends up and down, and the strong and weak drive motor 4C drives the strong and weak drive shaft support 4A to rotate forward and reverse. The outer periphery of the strong and weak drive shaft support 4A has a second male thread, and the second nut component 4B has a second female thread that matches the second male thread. The second nut component 4B is sleeved on the strong and weak drive shaft support 4A. When the strong and weak drive shaft support 4A rotates forward or reversely, the second nut component 4B moves upward or downward accordingly. Since the second nut component 4B can rotatably support the width drive shaft support 3A and the auxiliary shaft support 3C, when the second nut component 4B moves up and down, it can correspondingly drive the width drive mechanism 3 to move up and down as a whole. Combined with Figure 2 and Figure 3The two massage mechanisms 2 are located on both sides of the strong and weak drive shaft support 4A and the second nut member 4B along the left direction.

[0035] For the knocking drive mechanism 5, combined Figure 3 , which comprises: a knocking shaft support 5A, a transmission member 5B, and a knocking drive motor 5C driving the knocking shaft support 5A to rotate. The knocking shaft support 5A is an eccentric shaft support, which serves as a knocking drive shaft support. Specifically, in order to cooperate with both massage mechanisms 2 to perform knocking massage actions, the left and right sides of the knocking shaft support 5A are eccentrically designed, that is, the center lines of the left and right sides of the knocking shaft support 5A and the rotation axis of the knocking shaft support 5A have a preset eccentric distance, and then when it rotates, it drives the massage mechanism 2 to swing back and forth to perform knocking massage. The knocking drive motor 5C is connected to the knocking shaft support 5A through a transmission belt. The knocking shaft support 5A is supported between the first support frame and the second support frame, and the transmission member 5B has a first end 5B1 rotatably connected to the knocking shaft support 5A, and a second end 5B2 rotatably connected to the knocking connection part 14 of the massage mechanism 2. The first end 5B1 is sleeved on the knocking shaft support 5A and can move left and right relative to the knocking shaft support 5A. The rotation axis of the first end 5B1 hingedly moving relative to the knocking shaft support 5A, the rotation axis of the second end 5B2 hingedly moving relative to the knocking connecting portion 14 of the massage mechanism 2, and the swing axis of the massage mechanism 2 swinging back and forth are parallel to each other, so that the transmission member 5B drives the massage mechanism 2 to swing back and forth when the massage mechanism 2 moves up and down (such as Figure 7 and Figure 8 As shown). It is easy to understand. Figure 1 Similar to the implementation method, the knocking shaft support 5A also serves as a limiting shaft support, and the knocking shaft support 5A and the transmission member 5B also serve as a limiting mechanism, that is, the two cooperate to allow the massage arm 11 to move left and right and limit the massage arm 11 from rotating with the width driving shaft support 3A.

[0036] For the travel drive mechanism 6, combined Figure 2 , which includes: a first travel shaft support 6A, a travel drive motor 6B, and a second travel shaft support 6C. The first travel shaft support 6A has gear parts on both sides to match with the guide rail frame of the massage machine. The second travel shaft support 6C has roller parts (not shown) on both sides. The specific structure of the travel drive mechanism 6 configured on the guide rail frame of the massage machine is conventional technology, so it will not be repeated.

[0037] For the left and right position detection mechanism 7, combined Figure 2, which is a common photoelectric detection mechanism, comprising: a first scale member 7A and a first light detection member 7B. The first scale member 7A can move left and right with the right massage mechanism 2, and the first light detection member 7B is electrically connected to the control mechanism of the massage movement, and then the control mechanism can detect the position of the right massage mechanism 2. As the two massage mechanisms 2 are close to and away from each other, the position of the left massage mechanism 2 is symmetrical with the position of the right massage mechanism 2.

[0038] For the upper and lower position detection mechanism 8, combined Figure 3 It is a common photoelectric detection mechanism, which includes: a second scale member 8A that can move up and down with the second nut member 4B, and a second light detection member 8B that is arranged on the strong and weak driving motor 4C and electrically connected to the control mechanism.

[0039] For the walking position detection mechanism 9, combined with Figure 5 , which is a common photoelectric detection mechanism, which includes: a third scale member 9A, a third light detection member 9C. The first travel shaft support 6A drives the third scale member 9A to rotate through the gear transmission assembly. The third light detection member 9C is electrically connected to the control mechanism of the massage movement.

[0040] The present application further provides a massage machine, comprising a guide rail frame and a massage movement arranged on the guide rail frame, wherein the massage movement is any of the massage movements described above. The massage machine can be a massage chair or a massage cushion, and the guide rail frame can be a common L-shaped chair frame, which is conventional technology and will not be described in detail.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
