[0002] The patent application with publication number CN101683302B discloses a three-dimensional massage machine, which adjusts the protrusion of the massage head by means of a strong and weak driving component. The strong and weak driving component (also called the forward tilt adjustment mechanism) includes a gear and a circular arc rack matched therewith. The massage head is driven by the gear and the rack, and rotates forward around the center of the rack to adjust the protrusion of the massage head.

[0043] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various configurations. 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.

[0044] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0045] [First embodiment] Combination Figures 1 to 5 In the first embodiment, the massage movement of the present application includes a frame 1, a massage arm 2, a forward tilt adjustment mechanism P and a swing amplitude limiting mechanism M, and the forward tilt adjustment mechanism P is arranged between the frame 1 and the massage arm 2. Figure 5 The forward tilt adjustment mechanism P is used to control the movement of the massage arm 2 in the front-rear direction.

[0046] [Frame] Frame 1 includes two longitudinal plates and two transverse plates, the two longitudinal plates are spaced apart in the left-right direction, the two transverse plates are spaced apart in the up-down direction, and the two longitudinal plates and the two transverse plates are connected end to end to form a roughly rectangular frame structure. An axle support T is arranged between the two longitudinal plates.

[0047] [Massage Arm] The massage arm 2 includes a support arm and two massage heads. The support arm is roughly V-shaped, and the two massage heads are respectively arranged at the upper and lower ends of the support arm. It should be understood that the specific structure of the massage arm 2 is not limited thereto. In another embodiment, the support arm may be in a straight line shape and may only include one massage head. In another embodiment, the massage arm 2 may include a heating portion, which is installed on the support arm or integrated in the massage head.

[0048] [Tilt adjustment mechanism] The tilt adjustment mechanism P includes a first swing member P1, a second swing member P2, a rotating connecting member P3, a first shaft support P4 and a second shaft support P5. The lower side of the first swing member P1 is rotatably connected to the shaft support T, so that it can rotate forward and backward relative to the frame 1. The lower side of the second swing member P2 is pivotally connected to the inner side of the longitudinal plate, so that it can rotate forward and backward relative to the frame 1. Figure 5 , the rotation axis of the lower side of the first swinging member P1 is located in front of the rotation axis of the lower side of the second swinging member P2 (it should be understood that the expression "located in front of..." in this application includes the situations of "located directly in front, located above the front, and located below the front", combined with Figure 5 , this embodiment corresponds to the situation of "located slightly below the front side"). The front side of the rotating connection member P3 is configured to be rotatable relative to the upper side of the first swinging member P1. Specifically, the front side of the rotating connection member P3 is configured to be rotatable relative to the upper side of the first swinging member P1 by being rotatably sleeved on the first shaft support P4 arranged on the upper side of the first swinging member P1. The rear side of the rotating connection member P3 is configured to be rotatable relative to the upper side of the second swinging member P2. Specifically, the rear side of the rotating connection member P3 is configured to be rotatable relative to the upper side of the second swinging member P2 by being rotatably sleeved on the second shaft support P5 arranged on the upper side of the second swinging member P2. The first shaft support P4 and the second shaft support P5 both extend left and right. In this embodiment, the first shaft support P4 and the upper side of the first swinging member P1 and the front side of the rotating connection member P3 are rotatably matched, and the second shaft support P5 and the upper side of the second swinging member P2 and the rear side of the rotating connection member P3 are rotatably matched. Combined with Figure 5 , because the front side of the rotating connection member P3 can rotate relative to the upper side of the first swinging member P1, and the rear side of the rotating connection member P3 can rotate relative to the upper side of the second swinging member P2, the rotating connection member P3 plays a linkage role, so that the first swinging member P1 and the second swinging member P2 can swing back and forth synchronously. In this embodiment, the massage arm 2 is arranged on the rotating connection member P3, and when the first swinging member P1 and the second swinging member P2 swing, the massage arm 2 moves synchronously. It should be understood that the specific structure of the first swinging member P1 and the second swinging member P2 is not limited to the structure shown in the figure. In addition, on the basis of the first embodiment, the position of the massage arm 2 can also be adjusted. In another embodiment, the massage arm 2 can be arranged on the first swinging member P1 or the second swinging member P2. In the first embodiment, the first swinging member P1 is one, and the massage arm 2, the second swinging member P2 and the rotating connection member P3 are two corresponding groups, and are distributed on the left and right sides of the first swinging member P1. The forward tilt adjustment mechanism may include a forward tilt drive component ( Figures 1 to 5 (not shown), it can indirectly control the movement of the massage arm 2 by driving the first swing member P1 or the second swing member P2 to swing.

[0049] [Swing Limiting Mechanism] The swing limiting mechanism M is arranged between the frame 1 and the second swinging member 2 to limit the swinging range of the first swinging member. The swing limiting mechanism M includes a sliding rod member M1 and a sliding groove member M2. Figure 3, the slide bar M1 is arranged on the second swinging member P2, the slide groove member M2 is arranged on the inner side of the longitudinal plate of the frame 1, and the slide bar M1 and the slide groove opened on the slide groove member M2 are slidably matched. By limiting the swing amplitude of the second swinging member P2 in the front-to-back direction through the swing amplitude limiting mechanism M, the range of motion of the massage arm 2 in the front-to-back direction can be indirectly limited. In another embodiment, the positions of the slide bar M1 and the slide groove member M2 can be swapped. The position of the aforementioned swing amplitude limiting mechanism M is not limited to being arranged between the frame 1 and the second swinging member P2, and can also be adjusted to be arranged between the frame 1 and the first swinging member P1 to limit the front-to-back swing amplitude of the first swinging member P1, and indirectly limit the range of motion of the massage arm 2 in the front-to-back direction. The swing amplitude limiting mechanism M can adopt other deformation methods, such as being replaced by an elastic rope, a tension spring, etc.

[0050] Combination Figure 5 and Figure 6 The aforementioned forward tilt adjustment mechanism P uses the four-link principle to control the massage arm 2 to swing forward and backward. The first swing member P1, the second swing member P2, the rotating connecting member P3, and the horizontal plate located at the lower side correspond to the four connecting rods. Figure 6 , the distance between the pivot point on the front side of the rotating connection member P3 and the pivot point on the lower side of the first swinging member P1 is defined as L1, the distance between the pivot point on the rear side of the rotating connection member P3 and the pivot point on the lower side of the second swinging member P2 is defined as L2, and the distance between the pivot point on the front side of the rotating connection member P3 and the pivot point on the rear side of the rotating connection member P3 is defined as L3. In the first embodiment, L1 is greater than L2, and L2 is greater than L3. When the massage arm 2 is installed on the rotating connection member P3, by controlling the parameters of L1, L2, and L3, the activity trajectory of the massage arm 2 can be controlled so that the activity trajectory of the massage arm 2 is close to a straight line. The length ratio of L1 and L2 is, for example, between 1.5:1 and 1.2:1, and the length ratio of L2 and L3 is, for example, between 1.3:1 and 1.1:1.

[0051] It should be understood that Figures 1 to 5 Based on the illustrated first embodiment, the present application may also have other modified designs, which will be further illustrated below.

[0052] [Second embodiment] Combination Figure 7 and Figure 8 The massage movement of the second embodiment comprises a frame 1, a massage arm 2, a forward tilt adjustment mechanism 3 and a swing limiting mechanism M. The frame 1, the massage arm 2 and the swing limiting mechanism M have the same structure and function as those of the first embodiment, and will not be described in detail.

[0053] The tilt adjustment mechanism 3 of the second embodiment includes a first swing member 3A, a second swing member 3B, a rotating connecting member 3C, a first shaft support 3D, a second shaft support 3E, a tilt drive motor 3F, a tilt shaft 3G, a tilt gear 3H and a tilt rack 3I.

[0054] Among them, the structures and functions of the first swing member 3A, the second swing member 3B, the rotating connecting member 3C, the first shaft support 3D, and the second shaft support 3E are the same as those of the first embodiment. Specifically, the lower side of the first swing member 3A is rotatably sleeved on the shaft support T, so that it is configured to rotate forward and backward relative to the frame 1. The lower side of the second swing member 3B is pivotally connected to the inner side of the longitudinal plate of the frame 1, so that it is configured to rotate forward and backward relative to the frame 1, and the rotation axis of the lower side of the first swing member 3A is located in front of the rotation axis of the lower side of the second swing member 3B. The front side of the rotating connecting member 3C is configured to rotate relative to the upper side of the first swing member 3A by being rotatably sleeved on the first shaft support 3D configured on the upper side of the first swing member 3A. The rear side of the rotating connecting member 3C is configured to rotate relative to the upper side of the second swing member 3B by being rotatably sleeved on the second shaft support 3E configured on the upper side of the second swing member 3B. In this embodiment, the first shaft support 3D is rotatably matched with the upper side of the first swing member 3A and the front side of the rotating connection member 3C, and the second shaft support 3E is rotatably matched with the upper side of the second swing member 3B and the rear side of the rotating connection member 3C. Since the front side of the rotating connection member 3C can rotate relative to the upper side of the first swing member 3A, and the rear side of the rotating connection member 3C can rotate relative to the upper side of the second swing member 3B, the first swing member 3A and the second swing member 3B can swing back and forth synchronously. The massage arm 2 is arranged on the rotating connection member 3C, and when the first swing member 3A and the second swing member 3B swing, the massage arm 2 moves synchronously. In the second embodiment, the first swing member 3A is one, and the massage arm 2, the second swing member 3B and the rotating connection member 3C are two corresponding groups, and are distributed on the left and right sides of the first swing member 3A.

[0055] The tilt drive motor 3F, the tilt shaft 3G, the tilt gear 3H and the tilt rack 3I cooperate to form a tilt drive assembly that drives the first swing member 3A to swing forward and backward. The tilt drive motor 3F is arranged on the frame 1, the tilt shaft 3G is rotatably arranged on the frame 1 and is driven to rotate by the tilt drive motor 3F, the tilt gear 3H is sleeved on the tilt shaft 3G and rotates therewith, and the tilt rack 3I is arranged on the first swing member P1 and meshes with the tilt gear 3H.

[0056] The above is a detailed description of the second embodiment. Other features not mentioned in the second embodiment can also be understood by referring to the first embodiment, and will not be described in detail. In another embodiment, the forward tilting drive assembly of the second embodiment can be transformed to drive the second swinging member 3B to swing.

The shaft support T and the left and right sides of the first shaft support 3D are supported on two support plates K1 and K2, and a reinforcing rod K3 is arranged between the two support plates K1 and K2. The reinforcing rod K3 passes through the first swinging member 3A, and the two support plates K1 and K2 and the reinforcing rod K3 move with the first swinging member 3A.

[0059] The width driving mechanism 4 is used to drive the massage arm 2 to move in the left and right directions, so that the massage arm 2 can perform back massage on the user. The width driving mechanism 4 includes a width driving motor 4A, a width transmission component 4B, and a first shaft support 3D that also serves as a width driving shaft. The width driving motor 4A is disposed on the support plate K2. The width driving motor 4A drives the first shaft support 3D to rotate through the width transmission component 4B.

The bearing 3C-2 and the nut 3C-3 are installed in the mounting groove, and the cover 3C-4 covers the mounting groove. The front side of the rotating connecting member 3C is sleeved on the first shaft support 3D through the bearing 3C-2, so that the front side of the rotating connecting member 3C can rotate relative to the first shaft support 3D. In this embodiment, the rear side of the rotating connecting member 3C is also configured to be able to move left and right on the second shaft support 3E. The front side of the rotating connecting member 3C is also sleeved on the first shaft support 3D (width drive shaft) through the nut 3C-3. The internal thread of the nut 3C-3 is compatible with the external thread of the first shaft support 3D, so that the nut 3C-3 can transform the rotational action of the first shaft support 3D (width drive shaft) into the translational action of the rotating connecting member 3C in the left and right directions. The massage arm 2 is arranged on the main connecting rod 3C-1 of the rotating connecting member 3C. The use of a shaft support with an external thread and a nut to achieve the translation of the component is also adopted in the patent application CN201910252807.7.

The first shaft support 3-4 which also serves as the width driving shaft has an external thread. The adapter 3-6 has a nut (not shown), and the adapter 3-6 is sleeved on the first shaft support 3-4 (width driving shaft) through the nut. The internal thread of the nut is matched with the external thread of the first shaft support 3-4, so that the nut can transform the rotational movement of the first shaft support 3-4 (width driving shaft) into the translational movement of the adapter 3-6 in the left and right directions. When the adapter 3-6 moves left and right, it will drive the rotating connector 3-3 and the massage arm 2 to move left and right. The manner in which the adapter seat 3-6 cooperates with the first shaft support 3-4 to achieve the left and right movement of the adapter seat 3-6 can be understood by referring to the manner in which the rotating connection member 3C and the first shaft support 3D cooperate with each other in the aforementioned embodiment to achieve the left and right movement of the rotating connection member 3C, and will not be repeated here.

[0074] The travel drive mechanism 5 includes a travel drive motor 5A, an upper travel shaft 5B, and a shaft support T which also serves as a lower travel shaft.

The knocking transmission assembly 6B is a pulley transmission assembly. In this embodiment, the left and right sides of the shaft support 3-7 are eccentrically arranged, that is, the rotation axis of the second swinging member 3-2 relative to the shaft support 3-7 (knocking drive shaft) and the rotation axis of the shaft support 3-7 (knocking drive shaft) itself have a preset eccentricity. When the shaft support 3-7 (knocking drive shaft) rotates, the front side of the rotating connecting member 3-3 will be driven by the second swinging member 3-2 to reciprocate and vibrate relative to the adapter 3-6, so that the massage arm 2 performs a knocking massage.

[0076] The above is a specific description of the seventh embodiment. It should be understood that based on the sixth embodiment, the present application also has a variety of modified implementations, for example, the knocking drive mechanism can be omitted.

[0077] It should be noted that a control panel (not shown) for controlling the operation of the massage mechanism of the aforementioned embodiments may be disposed on the frame. The massage mechanism may also include a position detection mechanism for detecting the amount of movement of the massage arm in the front-to-back direction, left-to-right direction, and up-and-down direction, which will not be described in detail.
