Detailed Implementation

[0019] To make the objectives, technical solutions, 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 generally be arranged and designed in various different configurations. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, features in the following embodiments can be combined with each other.

[0021] [Massage device] combined with Figures 1 to 3 In one embodiment, the massager of this application includes a top shell 1, a bottom shell 2, a soft cloth 3, a strap 4, and a massage mechanism 5. The massager of this embodiment can be used to massage a user's limbs. The top shell 1 is equipped with a display screen and control buttons. The bottom shell 2 is connected to the top shell 1. The soft cloth 3 is installed on the bottom shell 2. The strap 4 is installed between the top shell 1 and the bottom shell 2. The strap 4 can be an elastic band with Velcro. The illustration only shows a portion of the structure of the strap 4. The massage mechanism 5 can be installed on the top shell 1 using screws. When the massage mechanism 5 is working, it massages the user through the soft cloth 3. The soft cloth 3 can also be replaced with a soft rubber material, such as silicone, which can provide waterproofing.

[0022] [Massage Mechanism] Combined with Figures 4 to 14 The massage mechanism 5 of one embodiment of this application includes a base 5A, a swing arm 5B, a first massage head 5C, a center seat 5D, a swing frequency control component 5E, a swing amplitude control component 5F, a limiting component 5G, a swing frequency drive motor 5H, a swing amplitude drive motor 5I, a swing frequency transmission mechanism 5J, a swing amplitude transmission mechanism 5K, an eccentric rod 5L, an adapter 5M, and a position detection mechanism 5N. The swing arm 5B, the first massage head 5C, and the center seat 5D are in multiple corresponding sets.

[0023] The base 5A is used to install other components of the massage mechanism 5. It has a semi-circular positioning groove corresponding to the oscillation frequency drive motor 5H and the oscillation amplitude drive motor 5I, and a sliding groove K for the center seat 5D to slide.

[0024] The swing arm 5B is a long strip structure with a long slot 5B-1 along its length.

[0025] The first massage head 5C is mounted on the swing arm 5B. The first massage head 5C can be a massage head with heating and light-emitting functions. The number of first massage heads 5C on each swing arm 5B can be adjusted according to product design requirements.

[0026] The center seat 5D has a base portion 5D1 and a sliding portion 5D2, with the sliding portion 5D2 located above the base portion 5D1. The base portion 5D1 is located within a slide groove K, limiting the movement of the center seat 5D within a set range. The sliding portion 5D2 passes through an elongated slot 5B-1 in the swing arm 5B, thereby slidingly engaging with the swing arm 5B. The sliding portion 5D2 is located between the outer end K2 and the inner end K1 of the swing arm 5B, allowing the swing arm 5B to rotate around it. By adjusting the position of the base portion 5D1 within the slide groove K, the relative position of the sliding portion 5D2 with the inner end K1 and the outer end K2 of the swing arm 5B can be adjusted, thereby controlling the swing amplitude of the outer end K2 of the swing arm 5B.

[0027] The swing frequency control component 5E is mounted on the base 5A via a T-shaped pin T1, thereby rotating around a first set central axis. In this embodiment, the inner ends K1 of multiple swing arms 5B are spaced apart along the outer periphery 5M-1 of the adapter 5M and are all rotatably connected to the adapter 5M (e.g., ...). Figure 9 The adapter 5M is rotatably connected to the frequency control component 5E via an I-shaped pin T2. ​​Specifically, the adapter 5M is rotatably sleeved on the eccentric rod 5L, which is eccentrically positioned on the frequency control component 5E (in this embodiment, it is integrally formed, but it can also be a separate component). The end of the eccentric rod 5L is provided with a cap 5O to prevent the adapter 5M from detaching from the frequency control component 5E. The cap 5O is held on the eccentric rod 5L by a fastening screw 5P. The rotation center axis of the adapter 5M is eccentrically positioned relative to the first set center axis. Because the adapter 5M can rotate relative to the frequency control component 5E, and the swing arms 5B can rotate relative to the adapter 5M, the swing arms 5B will not get stuck when the frequency control component 5E rotates. A second massage head (not shown) can be provided on the adapter 5M to make the massage range and massage techniques of the massage mechanism more comprehensive. Figure 16 To make the massage area more comprehensive, in another embodiment, a second massage head 5Q may be provided on the cap 5O, and the cap 5O may be designed as part of the second massage head 5Q, such as serving as the base of the second massage head 5Q. However, it should be understood that the second massage head 5Q may also be provided on the adapter 5M.

[0028] The amplitude control component 5F rotates around the second set center axis. In this embodiment, the amplitude control component 5F is sleeved on the frequency control component 5E, and the rotation center axes of the amplitude control component 5F and the frequency control component 5E coincide (i.e., the first set center axis and the second set center axis coincide). It should be understood that in another embodiment, the first set center axis and the second set center axis can be designed to be parallel and have a certain distance between them, or the two center axes can form a certain angle. The amplitude control component 5F can convert its own rotational motion into the movement motion of the center seat 5D within a set range. Specifically, in this embodiment, the amplitude control component 5F has a guide groove S that slides and engages with the sliding part 5D2 of the center seat 5D. The number of guide grooves S corresponds to the number of center seats 5D, and the extension direction of the guide groove S and the movement direction of the center seat 5D have a set angle (the shape and trajectory of the guide groove S are referenced). Figure 11 The included angle allows the guide groove S to push the sliding part 5D2 when the swing control member 5F rotates, thereby allowing the center seat 5D to move within a set range. In this embodiment, the swing control member 5F has an inner peripheral part N1 and an outer peripheral part N2. The guide groove S is formed on the outer peripheral part N2, and the inner peripheral part N1 is recessed relative to the outer peripheral part N2. The inner peripheral part N1 is rotatably fitted onto the swing frequency control member 5E. The limiting member 5G is disposed on the swing frequency control member 5E, and the limiting member 5G restricts the swing control member 5F from axially disengaging from the swing frequency control member 5E. By making the inner peripheral part N1 recessed relative to the outer peripheral part N2, and in conjunction with the limiting member 5G, the surfaces of the outer peripheral part N2 and the limiting member 5G can be substantially flush, making the overall structure more compact and thinner. To improve wear resistance, a wear-resistant gasket can be provided between the swing frequency control member 5E and the swing amplitude control member 5F.

[0029] The oscillation frequency control component 5E is driven to rotate around a set central axis via the oscillation frequency transmission mechanism 5J. In this embodiment, the oscillation frequency transmission mechanism 5J is a double-tooth structure, with one end being a helical gear (or worm gear) and the other end being a spur gear. The helical gear (or worm gear) end of the double-tooth structure meshes with the worm gear mounted on the oscillation frequency drive motor 5H; the spur gear end of the double-tooth structure meshes with the outer spur gear portion of the oscillation frequency control component 5E. It should be understood that the oscillation frequency transmission mechanism 5J can also be constructed from multi-stage gear transmissions, which will not be elaborated here. The oscillation amplitude control component 5F is driven to rotate via the oscillation amplitude transmission mechanism 5K. In this embodiment, the oscillation amplitude transmission mechanism 5K includes a double-tooth structure M1 and a rack M2. Rack M2 is an arc-shaped spur rack, which is mounted and fixed on the swing amplitude control component 5F. The center of rack M2 coincides with the rotation center axis of swing amplitude control component 5F. The double gear M1 has a helical gear (or worm gear) at one end and a spur gear at the other end. The helical gear (or worm gear) end meshes with the worm on the motor shaft of the swing amplitude drive motor 5I, and the spur gear end meshes with rack M2. It should be understood that, unlike this embodiment where the swing frequency control component 5E and the swing amplitude control component 5F are driven by different motors, in another embodiment, they can be driven by the same motor, which can be connected to the swing frequency control component 5E and the swing amplitude control component 5F respectively through two transmission mechanism paths.

[0030] The position detection mechanism 5N is used to detect the rotational displacement of the swing control component 5F. When the swing control component 5F rotates forward or backward, the guide groove S on it allows the center seat 5D to reciprocate linearly within the groove K. In this embodiment, the swing control component 5F is equipped with two triggering parts N3, and the position detection mechanism 5N is a micro switch. When the swing control component 5F rotates forward or backward to its limit position, the triggering part N3 will touch the micro switch, triggering an electrical signal. By checking whether the position detection mechanism 5N is triggered, it is possible to detect whether the rotational position of the swing control component 5F is at its limit position, thereby indirectly detecting whether the center seat 5D is at its limit position within the groove K. When the center seat 5D is at its limit position within the groove K, the control circuit of the massage mechanism (not shown in the figure) controls the motor to rotate forward or backward, preventing the center seat 5D from colliding within the groove K. The micro switch can also be replaced with a Hall sensor, optocoupler sensor, or other position detection mechanisms, which will not be elaborated here. The aforementioned position detection of the center seat 5D within the slide groove K only determines whether it is at two extreme positions. To more accurately detect the specific position of the center seat 5D within the slide groove K, a code disk sensor assembly can be installed on the motor shaft of the swing drive motor 5I to detect the number of motor rotations. The specific displacement of the center seat 5D can then be calculated using the gear ratio. When the position detection mechanism 5N is triggered by an electrical signal, the center seat 5D is considered to be in its initial position. By further detecting the specific displacement of the center seat 5D using the aforementioned method, the precise position of the center seat 5D within the slide groove K can be determined, thus revealing the relative position of the sliding part 5D2 and the elongated slot 5B-1. By controlling the relative position of the sliding part 5D2 within the elongated slot 5B-1 of the swing arm 5B, the swing amplitude of the first massage head can be precisely controlled, resulting in a wider range of motion for the massage head, making it controllable according to needs and thus enriching the massage head's trajectory. In another embodiment, the encoder sensor assembly can be mounted on the swing control component 5F to directly detect the number of rotations of the swing control component 5F, which can achieve the same function as described above, and will not be repeated here.

[0031] Combination Figure 15 In another embodiment, the massage mechanism of this application comprises multiple swing arms 5B, the inner ends of which are stacked and rotatably connected to a swing frequency control component (each swing arm 5B is rotatably sleeved on an eccentric rod 5L, which is eccentrically connected to the swing frequency control component). The rotation center axis of the swing arms 5B is eccentrically set relative to a first set center axis. The inner ends 5B1 of the multiple swing arms 5B are bent relative to the remaining portions 5B2. In this embodiment, the degree of bending of the inner ends 5B1 of each swing arm 5B relative to the remaining portions 5B2 gradually increases, so that the remaining portions 5B2 of each swing arm 5B can be substantially on the same plane. Figure 15 The cap installed at the end of the eccentric rod 5L is omitted; the cap prevents the inner end 5B1 of each swing arm 5B from disengaging from the eccentric rod 5L. Combined with... Figure 17,exist Figure 15 Based on the proposed solution, a second massage head 5Q can be installed on the cap 5O.

[0032] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
