[0056] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, so as to make the technical solution and beneficial effects of the present invention clearer. It should be understood that the drawings are provided for reference and illustration only, and are not intended to limit the present invention. The dimensions shown in the drawings are only for the purpose of clear description and do not limit the scale relationship.

[0057] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the utility model.

[0058] This invention provides a massage device for human body massage and relaxation. Figure 1-7 The present invention is illustrated in a specific embodiment of the massage device 100, which includes a first massage body 20, a second massage body 30, and a drive assembly 40.

[0059] The first massage body 20 has a first inner cavity 22, and the second massage body 30 has a second inner cavity 32. The first inner cavity 22 and the second inner cavity 32 are arranged front to back and communicate with each other, forming a generally cylindrical receiving cavity for accommodating the parts of the human body to be massaged, such as the limbs, waist, and hips. When the massage device 100 is in use, the drive component 40 causes the first massage body 20 to produce a first type of movement, such as a pinching movement; at the same time, it causes the second massage body 30 to produce a second type of movement, such as a rotational movement. The first massage body 20 and the second massage body 30 act simultaneously on the massaged parts in the receiving cavity in different ways, and the multiple massages combined provide the user with a better massage experience.

[0060] like Figure 3-4 As shown, the inner ends (closer to each other) of the first massage body 20 and the second massage body 30 are axially separated, forming a small gap between them to prevent interference between the first massage body 20 and the second massage body 30 during movement. In this embodiment, the first inner cavity 22 penetrates both axial ends of the first massage body 20, and the second inner cavity 32 penetrates the inner end of the second massage body 30. The resulting accommodating cavity is closed at the outer end of the second massage body 30 (the side opposite to the first massage body 20). In use, the area to be massaged by the user extends into the accommodating cavity from the outer end of the first massage body 20 (the side opposite to the second massage body 30).

[0061] The first massage body 20 and the second massage body 30 are preferably made of flexible materials, such as silicone, which have a soft touch and a certain degree of elastic cushioning, making the user's experience more comfortable. The second massage body 30 acts on the massaged area by rotating, and its inner wall surface (the wall surrounding the second inner cavity 32) is provided with a number of protrusions 34, such as raised dots, raised bumps, raised pillars, raised strips, etc., which not only makes the second massage body 30 easier to rotate, but also deepens the massage effect on the massaged area. The first massage body 20 acts on the massaged area by pinching, and its inner wall surface (the wall surrounding the first inner cavity 22) can be a smooth wall surface or it can be provided with protrusions; this utility model does not impose any restrictions on this.

[0062] The first massage body 20 includes a first clamping portion 24a and a second clamping portion 24b disposed opposite to each other, and the first inner cavity 22 is formed between the first clamping portion 24a and the second clamping portion 24b. Figure 1-7 In the illustrated embodiment, there are multiple first clamping portions 24a and second clamping portions 24b, respectively disposed on opposite sides of the housing 50 of the massage device 100. In other embodiments, the first clamping portion 24a and the second clamping portion 24b may be single. Furthermore, the number of first clamping portions 24a and the second clamping portions 24b may be the same or different; the first clamping portions 24a and the second clamping portions 24b may be one-to-one opposite or staggered, not limited to specific embodiments.

[0063] Under the action of the driving component 40, the first clamping portion 24a and the second clamping portion 24b swing towards or away from each other, and the first massage body 20 as a whole continuously opens and closes, creating a pinching effect on the massaged area in the accommodating cavity. Preferably, both the first clamping portion 24a and the second clamping portion 24b are curved columnar, similar to human fingers, which can simulate the kneading massage effect of human hands and effectively improve the user experience. In the illustrated embodiment, the ends of the first clamping portion 24a and the second clamping portion 24b are separated to facilitate their swinging. In some embodiments, elastic threads, strips, etc., can be connected between the ends of the first clamping portion 24a and the second clamping portion 24b, as long as it does not affect their swinging.

[0064] The drive assembly 40 includes a drive motor 41, a first transmission mechanism 42, and a second transmission mechanism 43. The drive motor 41 serves as the power source for the entire massage device 100 and is preferably a geared motor with an output speed of approximately 1000 rpm. The first massage body 20 is connected to the drive motor 41 via the first transmission mechanism 42, allowing its first clamping portion 24a and second clamping portion 24b to swing in opposite directions or back to back. The second massage body 30 is connected to the drive motor 41 via the second transmission mechanism 43, enabling it to rotate. Thus, by using the same power source to drive the first massage body 20 and the second massage body 30 to move in different ways, a dual effect is achieved on the massaged area, resulting in a better overall effect.

[0065] like Figure 8-10 As shown, the first transmission mechanism 42 includes a fixed base 44, a rotating member 45, and a sliding member 46 that cooperate with each other.

[0066] The fixed base 44 is fixedly disposed in the housing 50 of the massage device 100, and is fixedly connected to the motor housing of the drive motor 41 by screws or the like. The rotating member 45 is connected to the output shaft 412 of the drive motor 41 and rotates around an axis extending in a first direction (e.g., the X direction) under the action of the drive motor 41. The outer wall surface of the rotating member 45 is provided with a first sliding groove 452, which extends approximately spirally in the circumferential direction of the rotating member 45; the fixed base 44 is provided with a second sliding groove 442, and the first sliding groove 452 extends in the first direction. The sliding member 46 is provided with a slider 462, which simultaneously slidably engages with both the first sliding groove 452 and the second sliding groove 442, converting the rotation of the drive motor 41 into the reciprocating movement of the sliding member 46 in the first direction.

[0067] In the illustrated embodiment, the rotating component 45 is constructed as a rotating shaft and is fixedly sleeved on the output shaft 412 of the drive motor 41. The rotating component 45 and the output shaft 412 can be fixed circumferentially by keying, form fitting, etc., so that they can rotate synchronously. The fixed seat 44 is cylindrical and is sleeved on the rotating component 45; the sliding component 46 is also cylindrical and is sleeved on the fixed seat 44. The slider 462 extends inward from the sliding component 46, passes through the second slide groove 442 of the fixed seat 44, and extends into the first slide groove 452 of the rotating component 45. The slider 462 is preferably arc-shaped and can be adapted to the shape of the groove wall of the first slide groove 452. In this embodiment, the slider 462 is formed separately and fixedly connected to the sliding component 46 by screws, etc., which facilitates the assembly with other components. In some embodiments, the slider 462 and the sliding component 46 can be an integral structure.

[0068] Please also refer to Figure 11-12The first groove 452 includes a first helical segment 452a and a second helical segment 452b symmetrically arranged. The first helical segment 452a extends from the first proximal end point A1 in a clockwise direction toward the first distal end point B1, and the second helical segment B1 extends from the first proximal end point A1 in a counterclockwise direction toward the first distal end point B1. The first proximal end point A1 and the first distal end point B1 are spaced a certain distance apart in the axial direction of the rotating member 45. When the slider 462 slides from the first proximal end point A1 to the first distal end point B1 of the first groove 452, the slider 46 moves away from the fixed seat 44; conversely, when the slider 462 slides from the first distal end point B1 to the first proximal end point A1 of the first groove 452, the slider 46 moves toward the fixed seat 44.

[0069] In the illustrated embodiment, the first helical segment 452a and the second helical segment B1 both span the entire circumference in the circumferential direction, and the first proximal end point A1 and the first distal end point B1 are located on the same generatrix of the rotating member 45. In some embodiments, the first proximal end point A1 and the first distal end point B1 of the first groove 452 can be located on opposite sides of the rotating member 45, that is, they differ by half a circumference in the circumferential direction. In this case, the span of the first helical segment 452a and the second helical segment B1 in the circumferential direction can be half a circumference or an odd multiple of half a circumference. In some embodiments, the first groove 452 can be formed on the outer wall surface of the output shaft 412 of the drive motor 41. In this case, the rotating member 45 can be omitted, or the portion of the output shaft 412 with the first groove 452 can be regarded as the rotating member 45, thus appropriately simplifying the structure.

[0070] The fixed base 44, rotating member 45, and sliding member 46 cooperate to form a first power conversion unit, which converts the rotation of the drive motor 41 into the linear movement of the sliding member 46. The first transmission mechanism 42 also includes a first swing arm 47a and a second swing arm 47b. Each of the swing arms 47a and 47b is rotatably disposed in the housing 50 via a shaft 60 and is movably engaged with the sliding member 46 via a transmission rod 49. Together, they form a second power conversion unit, which converts the linear movement of the sliding member 46 into the swinging of the swing arms 47a and 47b around the shaft 60, thereby driving the first clamping part 24a and the second clamping part 24b of the first massage body 20 to swing towards or away from each other.

[0071] The first swing arm 47a and the second swing arm 47b have basically the same structure and are arranged approximately symmetrically. Each swing arm 47a and 47b includes a connecting section 471 and at least one swinging section 473 arranged at an angle to the connecting section 471. The ends of the connecting sections 471 of the two swing arms 47a and 47b respectively form a insertion groove 475 for pivotally connecting the transmission rod 49. The swinging sections 473 of the first swing arm 47a extend into a first clamping part 24a; the swinging sections 473 of the second swing arm 47b extend into a second clamping part 24b. The swinging sections 473 of the first swing arm 47a / second swing arm 47b can be single or multiple, the same number as the number of the first clamping parts 24a / second clamping parts 24b.

[0072] In this embodiment, the shaft 60 extends along a first direction, and the transmission rod 49 is inclined relative to the shaft 60. The transmission rod 49 is connected to the sliding member 46, and the two reciprocate synchronously in the first direction. Due to the inclined arrangement of the transmission rod 49, the movement of the transmission rod 49 in the first direction causes the ends of the connecting sections 471 of the swing arms 47a and 47b to be lifted or pressed down. Thus, the swing arms 47a and 47b swing in opposite directions with their respective shafts 60 as the center, causing the first clamping parts 24a and the second clamping parts 24b sleeved on their swing sections 473 to swing in opposite directions. The insertion groove 475 at the end of the connecting section 471 of the swing arms 47a and 47b is preferably a U-shaped groove, so that the transmission rod 49 has a certain amount of room to move within the insertion groove 475.

[0073] In this embodiment, the two transmission rods 49 are disposed on opposite sides of a sliding frame 48. The sliding frame 48 is connected to the sliding member 46 to reciprocate along with the sliding member 46 in a first direction. In this embodiment, the sliding member 46 is provided with a protrusion 464, and the sliding frame 48 is provided with a groove 482. The protrusion 464 and the groove 482 cooperate to fix the sliding member 46 and the sliding frame 48 in the first direction. In some embodiments, the transmission rod 49 can be directly formed on the sliding member 46, omitting the sliding frame 48; or, the portion of the sliding member 46 provided with the transmission rod 49 can be considered as the sliding frame, as long as the transmission rod 49 can reciprocate in the first direction.

[0074] The first swing arm 47a and the second swing arm 47b are made of rigid material, which can better transmit the force to the first massage body 20, resulting in greater clamping force in the first clamping portion 24a and the second clamping portion 24b. When molding the first massage body 20, the first swing arm 47a and the second swing arm 47b can be pre-placed in a mold, so that after molding, the first clamping portion 24a and the second clamping portion 24b are integrally wrapped around the swinging section 473 of the first swing arm 47a and the second swing arm 47b. Alternatively, when molding the first massage body 20, gaps can be pre-drilled in the first clamping portion 24a and the second clamping portion 24b, and then the swinging sections 473 of the first swing arm 47a and the second swing arm 47b can be inserted into the first clamping portion 24a and the second clamping portion 24b, respectively.

[0075] In the above embodiments, the two swing arms 47a and 47b of the first transmission mechanism 42 are rotatably disposed in the housing 50 via shafts 60, so that the first clamping portion 24a and the second clamping portion 24b can swing synchronously. When the two swing arms 47a and 47b swing towards each other, the first clamping portion 24a and the second clamping portion 24b close; when the two swing arms 47a and 47b swing away from each other, the first clamping portion 24a and the second clamping portion 24b open, thus continuously opening and closing to pinch the massaged area. In some embodiments, one of the two swing arms 47a and 47b can be fixed, so that one of the first clamping portions 24a and the second clamping portion 24b swings while the other remains stationary, which also allows the first clamping portion 24a and the second clamping portion 24b to open and close relative to each other, pinching the massaged area.

[0076] In some embodiments, a vibration motor 62 is further provided in the first clamping portion 24a and / or the second clamping portion 24b of the first massage body 20 (see...). Figure 5 This allows the first massage body 20 to further enhance the massage effect through vibration while pinching the massaged area.

[0077] In this embodiment, as Figure 11-12 As shown, the second transmission mechanism 43 is a gear transmission mechanism, including multiple meshing gears. One gear serves as an input wheel 432, connected to the output shaft 412 of the drive motor 41; the other gear serves as an output wheel 434, connected to the second massage body 30. The input wheel 432 and the output wheel 434 can be directly meshed, or one or more intermediate gears can be provided between the input wheel 432 and the output wheel 434. Through the gear transmission mechanism, not only can long-distance power transmission be achieved between the drive motor 41 and the second massage body 30, but the direction of power transmission can also be changed, facilitating the arrangement of the second massage body 30.

[0078] In this embodiment, the input wheel 432 of the second transmission mechanism 43 is connected to the rotating member 45, and the rotating member 45 drives the output shaft 412 of the drive motor 41. In some embodiments, the input wheel 432 of the second transmission mechanism 43 is directly connected to the output shaft 412 of the drive motor 41. It should be understood that the second transmission mechanism 43 can also be a belt pulley transmission mechanism, a worm gear transmission mechanism, or a combination of multiple transmission mechanisms, as long as it enables the second massage body 30 to rotate. Alternatively, the second massage body 30 can also be directly connected to the output shaft 412 of the drive motor 41, omitting the second transmission mechanism 43.

[0079] In the illustrated embodiment, a rigid shell 36, such as a plastic shell or a metal shell, is fitted onto the outer side of the second massage body 30 to provide support for the second massage body 30. The second massage body 30 can be injection molded onto the inner wall of the rigid shell 36 after the rigid shell 36 has been formed, thereby allowing the rigid shell 36 and the second massage body 30 to be integrally connected for synchronous rotation. Preferably, the closed end of the rigid shell 36 protrudes outward to form a bearing seat 362, which extends into the housing 50 and is pivotally connected to the central shaft 436 of the output wheel 434 of the second transmission mechanism 43. The central shaft 436 of the output wheel 434 and the bearing seat 362 can be fixed circumferentially by keying, form fitting, etc., thereby enabling the second massage body 30 to rotate.

[0080] In some embodiments, the second massage body 30 is further equipped with a vibration motor, which enables it to vibrate at high frequency during rotation, thereby further enhancing the massage effect.

[0081] like Figure 3-7 As shown, the housing 50 is generally L-shaped. The first massage body 20 is disposed on the upper side of the transverse portion of the housing 50, and the second massage body 30 is disposed on the inner side of the longitudinal portion of the housing 50. The housing 50 is preferably a double-layer structure, including a rigid inner shell 52 and a flexible outer shell 54 wrapped around the rigid inner shell 52. The first clamping part 24a, the second clamping part 24b and the flexible outer shell 54 can be an integral structure formed by injection molding. The drive assembly 40 is installed in the rigid inner shell 52, and the swinging segments 473 of the swing arms 47a and 47b of its first transmission mechanism 42 extend outward through the rigid inner shell 52 and are inserted into the first clamping part 24a and the second clamping part 24b.

[0082] The housing 50 also houses a control circuit board 56 and a battery 58. The battery 58 serves as the power source for the entire massage device 100 and is connected to electrical equipment, such as a drive motor 41 and a vibration motor 70, via the control circuit board 56. Preferably, the housing 50 is equipped with control keys 59, allowing the user to select different usage modes. This enables the first massage body 20 to have different swing amplitudes and frequencies, and the second massage body 30 to have different rotation speeds and directions. Simultaneously, the first massage body 20 and / or the second massage body 30 can also vibrate with an adjustable vibration frequency, thereby enhancing the massage effect of the massage device 100.

[0083] Figure 13-17 The following is another embodiment of the massage device of this utility model, which differs from the previous embodiment mainly in that the massage device 100' has a second massage body 30'. In this embodiment, the second inner cavity 32' of the second massage body 30' extends through both ends of its axial direction, and the accommodating cavity formed by the second massage body 30' and the first inner cavity 22 of the first massage body 20 has open ends.

[0084] In use, the massage device 100' of this embodiment allows the user's limbs to be inserted into the receiving cavity from either the outer end of the first massage body 20 or the outer end of the second massage body 30'. Since the receiving cavity is open at both ends, the user's limbs can extend outwards from either the outer end of the first massage body 20 or the second massage body 30'. For example, the user's palm can extend through the first massage body 20, allowing the first massage body 20 and the second massage body 30' to be positioned on the forearm and hindarm respectively for massage; similarly, the user's lower limbs can extend through the second massage body 30', allowing the first massage body 20 and the second massage body 30' to be positioned on the waist and buttocks respectively for massage, facilitating massage of different areas.

[0085] like Figure 16-17 As shown, the second massage body 30' is fitted with a hard shell 36', and a third groove 364 is formed on the outer wall surface of the hard shell 36'. The third groove 364 extends in a generally spiral shape in the circumferential direction of the hard shell 36'. A fixing pin 51 is fixedly disposed inside the shell 50, and the fixing pin 51 is slidably inserted into the third groove 364. When the second massage body 30' is driven to rotate, the fixing pin 51 slides along the third groove 364, causing the second massage body 30' to extend and retract in the first direction. That is to say, in this embodiment, the second massage body 30' can also reciprocate in the first direction while rotating, moving closer to or away from the first massage body 20, further enhancing its massage effect.

[0086] The third groove 364 is preferably a symmetrical structure, comprising two helical segments extending in opposite directions from the second proximal end point A2 to the second distal end point B2. In this embodiment, the circumferential width of the two helical segments of the third groove 364 is half a circumference. The second proximal end point A2 and the second distal end point B2 are axially spaced by a certain distance. When the fixing pin 51 slides along the third groove 364 from the second proximal end point A2 to the second distal end point B2, the second massage body 30' slides towards the first massage body 20; conversely, when the fixing pin 51 slides along the third groove 364 from the second distal end point B2 to the second proximal end point A2, the second massage body 30' slides away from the first massage body 20.

[0087] In this embodiment, the output wheel 434' of the second transmission mechanism 43' is sleeved on the rigid shell 36'. The outer wall surface of the rigid shell 36' is also provided with a guide groove 366, and the inner wall surface of the output wheel 434' is provided with a guide block 438. The guide block 438 slides with the guide groove 366, so that the movement of the second massage body 30 in the first direction is smooth and stable. There can be multiple guide grooves 366 / guide blocks 438, which are evenly spaced in the circumferential direction of the rigid shell 36' / output wheel 434'. In some embodiments, the guide block 438 can also be provided on the outer wall surface of the rigid shell 36', and correspondingly, the guide groove 366 can be provided on the inner wall surface of the output wheel 434'.

[0088] Figure 18-20 In another embodiment of the massage device of this utility model, unlike the previous embodiment, the driving component 40” of the massage device 100” in this embodiment includes two driving motors. The first driving motor 41a is connected to the first massage body 20 through the first transmission mechanism 42', and the second driving motor 41b is connected to the second massage body 30 through the second transmission mechanism 43.

[0089] The first transmission mechanism 42' includes a rotating member 45' and a sliding member 46' that cooperate with each other. The rotating member 45' is connected to a first drive motor 41a and rotates about an axis extending along a first direction (e.g., the X direction) under its drive. The rotating member 45' is provided with a first transmission shaft 454, which is eccentrically positioned relative to its axis of rotation. When the drive motor 41a is started, the first transmission shaft 454 revolves relative to the axis of rotation of the rotating member 45'. The sliding member 46' is provided with a fourth sliding groove 466, which is elongated and extends along a second direction (e.g., the Y direction), and the second direction is perpendicular to the first direction.

[0090] The first drive shaft 454 is movably inserted into the fourth slide groove 466. The two work together to convert the rotation of the first drive motor 41a into the reciprocating movement of the sliding member 46' in a third direction (such as the Z direction). The third direction is perpendicular to the first direction and the second direction.

[0091] The sliding member 46' is provided with a protruding second drive shaft 468, which extends along a first direction. The first swing arm 47a and the second swing arm 47b are rotatably disposed in the housing 50 via a shaft 60. Each swing arm 47a, 47b includes a connecting section 471 and at least one swinging section 473, wherein the end of the connecting section 471 is formed with an insertion groove 475, and the second drive shaft 468 is movably inserted into the insertion groove 475 of the connecting section 471 of the two swing arms 47a, 47b.

[0092] When the slider 46' moves upward and reciprocates, the end of the connecting section 471 of the swing arms 47a and 47b is lifted or pressed down, thereby causing the two swing arms 47a and 47b to swing around the shaft 60, driving the first clamping part 24a and the second clamping part 24b on the swing section 473 covering it to swing towards or away from each other, thereby achieving pinching massage.

[0093] The second transmission mechanism 43 may be a gear transmission mechanism, a belt pulley transmission mechanism, etc., and is connected between the second drive motor 41b and the second massage body 30.

[0094] By setting two drive motors 41a and 41b, the movement of the first massage body 20 and the second massage body 30 can be controlled independently. Users can activate only one of the massage bodies 20 and 30 for massage, or activate both massage bodies 20 and 30 simultaneously, making it more convenient to use. In addition, setting two drive motors 41a and 42'b simplifies the transmission mechanism between the drive motors 41a and 42b and the massage bodies 20 and 30. For example, in this embodiment, the first transmission mechanism 42' achieves the conversion between rotational motion and linear motion through the cooperation of the eccentrically set first transmission shaft 454 and the fourth slide groove 466, which is simpler than the cooperation of the second slide groove 442 of the fixed seat 44, the first slide groove 452 of the rotating member 45, and the slider of the sliding member 46 in the previous two embodiments.

[0095] The two massage bodies of this utility model simultaneously act on the massaged area in different ways, and the superposition of multiple effects provides the user with a better massage experience. The above description is merely a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the embodiments listed above. Any simple variations or equivalent substitutions of the technical solutions that can be obviously obtained by those skilled in the art within the scope of the technology disclosed in this utility model fall within the protection scope of this utility model.
