Mode for Carrying Out the Invention

[0018] In order to make the objects, technical means, and advantages of the embodiments of the present invention more clear, the present invention will be described in more detail below with reference to the drawings. Usually, the components of the embodiments of the present invention described and shown in these drawings can be arranged and designed in various forms. Based on the embodiments of the present invention, all other embodiments obtained on the premise that those skilled in the art do not perform creative labor are all included in the protection scope of the present invention.

[0019] Hereinafter, some embodiments of the present invention will be described in detail with reference to the drawings. As long as there is no contradiction, the features of the following embodiments can be combined with each other.

[0020] <Massager> Referring to Figures 1 to 3, in one embodiment, the massager of the present invention includes an upper case 1, a lower case 2, a flexible cloth 3, a strap 4, and a massage machine core 5. The massager of this embodiment is used to massage the limbs of a user. The upper case 1 is provided with a display and operating buttons. The lower case 2 is connected to the upper case 1. The flexible cloth 3 is attached to the lower case 2. The strap 4 is attached between the upper case 1 and the lower case 2. The strap 4 may be an elastic band or may have Velcro, but only a part of the structure of the strap 4 is shown in the figures. The massage machine core 5 can be attached to the upper case 1 by screw posts. When the massage machine core 5 is activated, it massages the user via the flexible cloth 3. The flexible cloth 3 may be replaced with a soft rubber material, such as silicone, to provide waterproofing.

[0021] <Massage Machine Core> Referring to Figures 4 to 14, the massage machine core 5 of one embodiment of the present invention comprises a base 5A, a swing arm 5B, a first massage head 5C, a center base 5D, a swing frequency control member 5E, a swing width control member 5F, a regulating member 5G, a swing frequency drive motor 5H, a swing width drive motor 5I, a swing frequency transmission mechanism 5J, a swing width transmission mechanism 5K, and an eccentric rod Includes 5L, adapter 5M, and position detection mechanism 5N. The oscillating arm 5B, first massage head 5C, and center base 5D are in multiple corresponding sets.

[0022] The base 5A is used to mount other components of the massage machine core 5 and has a semicircular housing corresponding to the oscillation frequency drive motor 5H and the oscillation width drive motor 5I, and a sliding groove K on which the center base 5D slides.

[0023] The oscillating arm 5B has an elongated structure, and an elongated groove 5B-1 is provided along its length.

[0024] The first massage head 5C is attached to the rocking arm 5B. The first massage head 5C may also have heating and light-emitting functions. The number of first massage heads 5C on each rocking arm 5B can be adjusted according to the needs of the product design.

[0025] The center base 5D has a base portion 5D1 and a sliding contact portion 5D2. The sliding contact portion 5D2 is located above the base portion 5D1. The base portion 5D1 is located in the slide groove K and restricts the movement of the center base 5D within a set range. The sliding contact portion 5D2 is slidably fitted onto the rocking arm 5B by passing through the elongated groove 5B-1 of the rocking arm 5B. The sliding contact portion 5D2 is located between the outer end K2 and the inner end K1 of the rocking arm 5B, allowing the rocking arm 5B to rotate around the sliding contact portion 5D2. By adjusting the position of the base portion 5D1 in the slide groove K, the relative position between the sliding contact portion 5D2 and the inner end K1 and outer end K2 of the rocking arm 5B can be adjusted. This controls the range of motion of the outer end K2 of the rocking arm 5B.

[0026] The oscillation frequency control member 5E is attached to the base 5A by a T-shaped pin component T1 and rotates around a first set central axis. In this embodiment, the inner ends K1 of the multiple oscillation arms 5B are spaced apart along the outer circumference 5M1 of the adapter 5M and are all rotatably connected to the adapter 5M (rotatably connected by an I-shaped pin component T2, as shown in Figure 9). The adapter 5M is rotatably connected to the oscillation frequency control member 5E. Specifically, the adapter 5M is rotatably fitted onto an eccentric rod 5L. The eccentric rod 5L is eccentrically provided on the oscillation frequency control member 5E (in this embodiment it is integrally molded, but it may be formed in a separate form). A cap 5O is provided at the end of the eccentric rod 5L to restrict the detachment of the adapter 5M from the oscillation frequency control member 5E. The cap 5O is held on the eccentric rod 5L by a fastening screw 5P. The pivot axis of the adapter 5M is set eccentrically with respect to the first set pivot axis. Since the adapter 5M is rotatable relative to the oscillation frequency control member 5E, and the oscillation arms 5B are rotatable relative to the adapter 5M, the oscillation arms 5B do not jam when the oscillation frequency control member 5E rotates. By providing a second massage head (not shown) on the adapter 5M, the massage range and massage technique of the massage machine core can be made more comprehensive. Referring to Figure 16, in other embodiments, a second massage head 5Q may be provided on the cap 5O in order to make the massage area more omnidirectional. Alternatively, the cap 5O may be designed as part of the second massage head 5Q, or it may function as a base for the second massage head 5Q, for example. However, if the second massage head 5Q is on the adapter 5M or eccentric rod Please understand that it may be acceptable to include this feature in the 5L version.

[0027] The oscillation width control member 5F rotates around the second set central axis. In this embodiment, the oscillation width control member 5F is fitted onto the oscillation frequency control member 5E. The rotational central axes of the oscillation width control member 5F and the oscillation frequency control member 5E coincide (i.e., the first set central axis and the second set central axis coincide). However, it should be understood that in other embodiments, the first set central axis and the second set central axis may be designed to be parallel and have a constant distance between them, or the two central axes may be designed to form a constant angle. The oscillation width control member 5F can convert its own rotational motion into the movement motion of the center base 5D within a set range. Specifically, the oscillation width control member 5F in this embodiment is provided with a guide groove S into which the sliding contact portion 5D2 of the center base 5D is slidably fitted. The number of guide grooves S corresponds to the number of center bases 5D, and the extension direction of the guide grooves S and the movement direction of the center base 5D form a predetermined angle (see Figure 11 for the shape and trajectory of the guide grooves S). Due to the existence of this angle, when the oscillation width control member 5F rotates, the guide grooves S can push the sliding contact portion 5D2, thereby allowing the center base 5D to move within the set range. In this embodiment, the oscillation width control member 5F comprises an inner circumference portion N1 and an outer circumference portion N2. The guide grooves S are provided on the outer circumference portion N2. The inner circumference portion N1 is recessed compared to the outer circumference portion N2 and is rotatably fitted to the oscillation frequency control member 5E. The regulating member 5G is provided on the oscillation frequency control member 5E and restricts the detachment of the oscillation width control member 5F from the oscillation frequency control member 5E in the axial direction. By recessing the inner circumference N1 compared to the outer circumference N2 and restricting it with the restricting member 5G, the surfaces of the outer circumference N2 and the restricting member 5G can be made nearly flush, allowing the overall structure to be made more compact and thinner. To improve wear resistance, a wear-resistant washer may be provided between the oscillation frequency control member 5E and the oscillation width control member 5F.

[0028] The oscillation frequency control member 5E is driven to rotate around a set central axis by being ductilely connected to the oscillation frequency drive motor 5H via the oscillation frequency transmission mechanism 5J. In this embodiment, the oscillation frequency transmission mechanism 5J is a double gear, with one end being a helical gear (or worm wheel) and the other end being a spur gear. The helical gear (or worm wheel) at one end of the double gear meshes with a worm provided on the oscillation frequency drive motor 5H. The spur gear at the other end of the double gear meshes with the outer circumferential spur teeth of the oscillation frequency control member 5E. However, it should be understood that the oscillation frequency transmission mechanism 5J may be configured by a multi-stage gear transmission, but a detailed explanation is omitted here. The oscillation width control member 5F is driven to rotate by being ductilely connected to the oscillation width drive motor 5I via the oscillation width transmission mechanism 5K. In this embodiment, the oscillation width transmission mechanism 5K includes a double gear M1 and a rack M2. The rack M2 is an arc-shaped spur gear rack fixed to the oscillation width control member 5F. The center of the rack M2 coincides with the pivot axis of the oscillation width control member 5F. The double gear M1 has a helical gear (or worm wheel) at one end and a spur gear at the other end. The helical gear (or worm wheel) at one end meshes with a worm provided on the motor shaft of the oscillation width drive motor 5I, and the spur gear at the other end meshes with the rack M2. However, unlike this embodiment in which the oscillation frequency control member 5E and the oscillation width control member 5F are driven by different motors, in other embodiments it is possible to drive both with the same motor. In this case, the motor is connected to the oscillation frequency control member 5E and the oscillation width control member 5F via two transmission mechanism paths.

[0029] The position detection mechanism 5N is used to detect the rotational displacement of the oscillation width control member 5F. When the oscillation width control member 5F rotates in the forward and reverse directions, the guide groove S allows the center base 5D to reciprocate linearly within the slide groove K. In this embodiment, the oscillation width control member 5F is provided with two trigger parts N3. The position detection mechanism 5N is a microswitch. When the oscillation width control member 5F rotates forward or backward and reaches a limit position, the trigger parts N3 contact the microswitch and trigger an electrical signal. By determining whether the position detection mechanism 5N has been triggered, it is possible to detect whether the rotational position of the oscillation width control member 5F is at its limit position, and thereby indirectly determine whether the center base 5D is at its limit position within the slide groove K. When the center base 5D is at its limit position within the slide groove K, the risk of the center base 5D colliding within the slide groove K can be eliminated by controlling the forward or reverse rotation of the motor using the control circuit (not shown) of the massage machine core. The microswitch may be replaced with a position detection mechanism such as a Hall sensor or a photocoupler sensor, but a detailed explanation is omitted here. The detection of whether the center base 5D is located within the slide groove K can only determine whether it is in one of two limit positions. To more accurately detect the specific position of the center base 5D within the slide groove K, an encoder sensor assembly can be provided on the motor shaft of the oscillation width drive motor 5I to detect the number of motor rotations, and furthermore, the specific displacement of the center base 5D can be estimated through the gear transmission ratio. When the position detection mechanism 5N triggers an electrical signal, the center base 5D is considered to be in the starting position, and by detecting the specific displacement of the center base 5D through the aforementioned method, the specific position of the center base 5D in the slide groove K can be accurately determined, and consequently, the relative position between the sliding contact portion 5D2 and the elongated groove 5B-1 can be determined. By controlling the relative position of the sliding contact portion 5D2 in the elongated groove 5B-1 of the oscillating arm 5B, the oscillation range of the first massage head can be precisely controlled, enabling a wider range of motion of the massage head and allowing it to be controlled according to needs, thereby achieving diversity in the trajectory of the massage head.In other embodiments, the same function can be achieved by attaching the encoder sensor assembly to the oscillation range control member 5F and directly detecting the number of rotations of the oscillation range control member 5F, but a detailed explanation is omitted.

[0030] Referring to Figure 15, in another embodiment, the massage machine core of the present invention is provided with the inner ends of a plurality of oscillating arms 5B stacked on top of each other, and each is rotatably provided with an oscillating frequency control member. 5E (Both are rotatably fitted to the eccentric rod 5L, and the eccentric rod 5L is a oscillation frequency control member) 5E (Connected eccentrically to the first set central axis). The pivot axis of the swing arm 5B is set eccentrically with respect to the first set central axis. The inner ends 5B1 of the multiple swing arms 5B are bent relative to the other parts 5B2. In this embodiment, by sequentially increasing the degree of bending of the inner end 5B1 of each swing arm 5B relative to the other parts 5B2, the other parts 5B2 of each swing arm 5B are positioned in approximately the same plane. Figure 15 omits the cap attached to the end of the eccentric rod 5L. 5O This can restrict the detachment of the inner end 5B1 of each swinging arm 5B from the eccentric rod 5L. Referring to Figure 17, a second massage head 5Q may be provided on the cap 5O based on the technical proposal shown in Figure 15.

[0031] 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 modification or substitution that a person skilled in the art can easily conceive within the scope of the art disclosed herein should be included within the scope of protection of the present invention.
