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

[0057] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the invention.

[0058] The invention provides a massage device for massaging and relaxing the human body. Figure 1-7 The figure shows a specific embodiment of the massage device of the present invention. The massage device 100 includes a first massage body 20 , a second massage body 30 and a driving 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 and back and connected to each other, and together form a roughly columnar accommodation cavity for accommodating the parts of the human body to be massaged, such as limbs, waist and hips, etc. When the massage device 100 is in use, the driving component 40 causes the first massage body 20 to generate a first mode of movement, such as a pinching movement, etc.; at the same time, the second massage body 30 generates a second mode of movement, such as a rotational movement, etc. The first massage body 20 and the second massage body 30 act on the massaged parts in the accommodation cavity in different ways at the same time, and the multiple massages are superimposed to give the user a better massage experience.

[0060] like Figure 3-4 As shown, the inner ends (side ends close to each other) of the first massage body 20 and the second massage body 30 are separated in the axial direction, and a small gap is formed between them to prevent the first massage body 20 and the second massage body 30 from interfering with each other during movement. In this embodiment, the first inner cavity 22 passes through the axial ends of the first massage body 20, and the second inner cavity 32 passes through the inner end of the second massage body 30, and the formed accommodation cavity is closed at the outer end (the side end away from the first massage body 20) of the second massage body 30. When in use, the part that the user needs to massage extends from the outer end (the side end away from the second massage body 30) of the first massage body 20 into the accommodation cavity.

[0061] The first massage body 20 and the second massage body 30 are preferably made of flexible materials, such as silicone, etc., and have a soft touch and a certain elastic buffering effect, making the user feel more comfortable. The second massage body 30 acts on the massaged part by rotating, and its inner wall surface (the wall surface surrounding the second inner cavity 32) is provided with a number of protrusions 34, such as convex points, convex hulls, convex columns, convex strips, etc., which not only makes the second massage body 30 easier to rotate, but also deepens the massage effect on the massaged part. The first massage body 20 acts on the massaged part by pinching, and its inner wall surface (the wall surface surrounding the first inner cavity 22) can be a smooth wall surface or be provided with protrusions, and the present invention does not limit this.

[0062] The first massage body 20 includes a first clamping portion 24a and a second clamping portion 24b which are arranged 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, the first clamping portion 24a and the second clamping portion 24b are both multiple, and are 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. In addition, the number of the first clamping portion 24a and the second clamping portion 24b may be the same or different; the first clamping portion 24a and the second clamping portion 24b may be opposite to each other one by one or staggered with each other, which is not limited to the specific embodiment.

[0063] Under the action of the driving assembly 40, the first clamping portion 24a and the second clamping portion 24b swing toward or away from each other, and the first massage body 20 as a whole is constantly opened and closed, producing a pinching effect on the massaged part in the accommodating cavity. Preferably, the first clamping portion 24a and the second clamping portion 24b are both curved columns, similar to human fingers, which can simulate the massage effect of human hand kneading 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, an elastic wire, strip, etc. may 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 driving assembly 40 includes a driving motor 41, a first transmission mechanism 42 and a second transmission mechanism 43. The driving motor 41 is used as the power source of the entire massage device 100, and is preferably a reduction motor with an output speed of about 1000 rpm. The first massage body 20 is connected to the driving motor 41 through the first transmission mechanism 42, so that its first clamping part 24a and the second clamping part 24b can swing toward or away from each other; the second massage body 30 is connected to the driving motor 41 through the second transmission mechanism 43, so that it can rotate. In this way, the first massage body 20 and the second massage body 30 are driven to move in different ways by the same power source, forming a dual effect on the massaged parts, and the overall effect is better.

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

[0066] The fixing seat 44 is fixedly arranged in the housing 50 of the massage device 100, such as being fixedly connected to the motor housing of the driving motor 41 by screws or the like. The rotating member 45 is connected to the output shaft 412 of the driving motor 41, and rotates around an axis extending in a first direction (such as the X direction) under the action of the driving motor 41. The outer wall surface of the rotating member 45 is provided with a first slide groove 452, and the first slide groove 452 extends roughly in a spiral shape in the circumferential direction of the rotating member 45; the fixing seat 44 is provided with a second slide groove 442, and the first slide groove 452 extends in the first direction. The sliding member 46 is provided with a slider 462, and the slider 462 is slidably matched with the first slide groove 452 and the second slide groove 442 at the same time, so as to convert the rotation of the driving motor 41 into the reciprocating movement of the sliding member 46 in the first direction.

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

[0068] Please also see Figure 11-12The first slide groove 452 includes a first spiral segment 452a and a second spiral segment 452b symmetrically arranged, wherein the first spiral segment 452a extends from the first proximal end point A1 toward the first distal end point B1 in a clockwise direction, and the second spiral segment B1 extends from the first proximal end point A1 toward the first distal end point B1 in a counterclockwise direction, and 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 slide 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 of the first slide groove 452 to the first proximal end point A1, the slider 46 moves toward the fixed seat 44.

[0069] In the illustrated embodiment, the circumferential spans of the first spiral segment 452a and the second spiral segment B1 are both the entire circumference, 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 slide 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 circumferential spans of the first spiral segment 452a and the second spiral segment B1 can be half a circumference or an odd multiple of half a circumference. In some embodiments, the first slide groove 452 can be formed on the outer wall surface of the output shaft 412 of the drive motor 41, in which case the rotating member 45 can be omitted, or the portion of the output shaft 412 with the first slide groove 452 can be regarded as the rotating member 45, and the structure can be appropriately simplified.

[0070] The fixed seat 44, the rotating member 45 and the sliding member 46 cooperate with each other to form a first power conversion unit, which converts the rotation of the driving 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 through a shaft 60, and is movably matched with the sliding member 46 through a transmission rod 49, forming a second power conversion unit as a whole, which converts the linear movement of the sliding member 46 into the swing of the swing arms 47a and 47b around the shaft 60, thereby driving the first clamping portion 24a and the second clamping portion 24b of the first massage body 20 to swing toward 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 roughly symmetrically. Each swing arm 47a, 47b includes a connecting section 471 and at least one swing section 473 arranged at an angle to the connecting section 471. The ends of the connecting sections 471 of the two swing arms 47a, 47b respectively form a plug-in slot 475 for pivoting the transmission rod 49; the swing sections 473 of the first swing arm 47a respectively extend into a first clamping portion 24a; the swing sections 473 of the second swing arm 47b respectively extend into a second clamping portion 24b. The swing sections 473 of the first swing arm 47a / the second swing arm 47b can be single or multiple, the same number as the first clamping portion 24a / the second clamping portion 24b.

[0072] In this embodiment, the shaft 60 extends along the first direction, and the transmission rod 49 is arranged obliquely relative to the shaft 60. The transmission rod 49 is connected to the sliding member 46, and the two move back and forth in the first direction synchronously. Since the transmission rod 49 is arranged obliquely, 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, so that the swing arms 47a and 47b are swung back and forth with their corresponding shaft 60 as the center, driving the first clamping part 24a and the second clamping part 24b sleeved on the swinging section 473 to swing toward each other or back and forth. The plug-in slot 475 at the end of the connecting section 471 of the swing arms 47a and 47b is preferably a U-shaped slot, so that the transmission rod 49 has a certain movable space in the plug-in slot 475.

[0073] In this embodiment, the two transmission rods 49 are arranged on opposite sides of a sliding frame 48, and the sliding frame 48 is connected to the sliding member 46 so as to reciprocate in the first direction with the sliding member 46. In this embodiment, the sliding member 46 is provided with a boss 464, and the sliding frame 48 is provided with a groove 482, and the boss 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, and the sliding frame 48 is omitted; or, the part of the sliding member 46 provided with the transmission rod 49 is regarded as a sliding frame, as long as the transmission rod 49 can be reciprocated in the first direction.

[0074] The first swing arm 47a and the second swing arm 47b are made of hard materials, which can better transmit the force to the first massage body 20, so that the first clamping part 24a and the second clamping part 24b have greater clamping force. When forming the first massage body 20, the first swing arm 47a and the second swing arm 47b can be placed in the mold in advance, so that the first clamping part 24a and the second clamping part 24b are integrally wrapped on the swinging section 473 of the first swing arm 47a and the second swing arm 47b after forming. Of course, when forming the first massage body 20, it is also possible to reserve holes in the first clamping part 24a and the second clamping part 24b, and then insert the swinging sections 473 of the first swing arm 47a and the second clamping part 24b into the first clamping part 24a and the second clamping part 24b respectively.

[0075] In the above embodiment, the two swing arms 47a, 47b of the first transmission mechanism 42 are rotatably disposed in the housing 50 through the shaft 60, respectively, so that the first clamping part 24a and the second clamping part 24b can swing synchronously. When the two swing arms 47a, 47b swing toward each other, the first clamping part 24a and the second clamping part 24b are closed; when the two swing arms 47a, 47b swing away from each other, the first clamping part 24a and the second clamping part 24b are opened, and the massaged part is continuously opened and closed to pinch the massaged part. In some embodiments, one of the two swing arms 47a, 47b can be fixed, so that one of the first clamping part 24a and the second clamping part 24b swings and the other one does not move, which can also make the first clamping part 24a and the second clamping part 24b open and close relative to pinch the massaged part.

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

[0077] In this embodiment, Figure 11-12 As shown, the second transmission mechanism 43 is a gear transmission mechanism, including a plurality of gears meshing with each other, wherein one gear is used as an input wheel 432, connected to the output shaft 412 of the driving motor 41; another gear is used as an output wheel 434, connected to the second massage body 30. The input wheel 432 and the output wheel 434 may be directly meshed, or one or more intermediate gears may be provided between the input wheel 432 and the output wheel 434. Through the gear transmission mechanism, not only can the long-distance transmission of power be realized between the driving motor 41 and the second massage body 30, but also the direction of the power transmission can be changed, which facilitates 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 is transmitted to the output shaft 412 of the driving motor 41 through the rotating member 45. In some embodiments, the input wheel 432 of the second transmission mechanism 43 is directly connected to the output shaft 412 of the driving motor 41. It should be understood that the second transmission mechanism 43 can also be a pulley transmission mechanism, a worm gear transmission mechanism, etc., or a combination of multiple transmission mechanisms, as long as the second massage body 30 can be rotated. In addition, the second massage body 30 can also be directly connected to the output shaft 412 of the driving motor 41, and the second transmission mechanism 43 is omitted.

[0079] In the illustrated embodiment, a hard shell 36, such as a plastic shell or a metal shell, is sleeved on the outer side of the second massage body 30 to provide support for the second massage body 30. After the hard shell 36 is formed, the second massage body 30 can be injection molded on the inner wall surface of the hard shell 36, so that the hard shell 36 and the second massage body 30 can be integrally connected to rotate synchronously. Preferably, the closed end of the hard shell 36 protrudes outward to form a shaft seat 362, and the shaft seat 362 extends into the housing 50 and is pivotally connected to the central axis 436 of the output wheel 434 of the second transmission mechanism 43. The central axis 436 of the output wheel 434 and the shaft seat 362 can be fixed in the circumferential direction by keying, shape matching, etc., so as to drive the second massage body 30 to rotate.

[0080] In some embodiments, a vibration motor is embedded in the second massage body 30 so that it can vibrate at a high frequency during rotation, thereby further enhancing the massage effect.

[0081] like Figure 3-7 As shown, the shell 50 is generally L-shaped as a whole, the first massage body 20 is arranged on the upper side of the transverse part of the shell 50, and the second massage body 30 is arranged on the inner side of the longitudinal part of the shell 50. The shell 50 is preferably a double-layer structure, including a hard inner shell 52 and a flexible outer shell 54 wrapped on the hard inner shell 52, and the first clamping part 24a, the second clamping part 24b and the flexible outer shell 54 can be an integral structure of injection molding. The driving assembly 40 is installed in the hard inner shell 52, and the swing section 473 of the swing arm 47a, 47b of the first transmission mechanism 42 thereof extends outward through the hard inner shell 52 and is inserted into the first clamping part 24a, the second clamping part 24b.

[0082] The housing 50 is also provided with a control circuit board 56 and a battery 58. The battery 58 is used as the power source of the entire massage device 100 and is connected to electrical devices such as the drive motor 41 and the vibration motor 70 through the control circuit board 56. The housing 50 is preferably provided with a control key 59, through which the user can select different usage modes, so that the first massage body 20 can have different swing amplitudes and swing frequencies, and the second massage body 30 can have different speeds and directions. At the same time, the first massage body 20 and / or the second massage body 30 can also vibrate and the vibration frequency is adjustable, so that the massage effect of the massage device 100 of the present invention is better.

[0083] Figure 13-17 Another embodiment of the massage device of the present invention is shown, which is different from the previous embodiment mainly in the second massage body 30' of the massage device 100. In this embodiment, the second inner cavity 32' of the second massage body 30' runs through both ends of the axial direction, and both ends of the accommodating cavity formed together with the first inner cavity 22 of the first massage body 20 are open.

[0084] When the massage device 100' of this embodiment is in use, the user's limbs can be inserted into the accommodating cavity from the outer end of the first massage body 20, or can be inserted into the accommodating cavity from the outer end of the second massage body 30'. Since both ends of the accommodating cavity are open, the user's limbs can extend outward from the outer end of the first massage body 20 or the second massage body 30'. For example, the user's palm can pass through the first massage body 20, and the first massage body 20 and the second massage body 30' can be positioned at the forearm and the back arm of the arm for massage; for another example, the user's lower limbs can pass through the second massage body 30', and the first massage body 20 and the second massage body 30' can be positioned at the waist and the buttocks for massage, so as to facilitate massaging different parts.

[0085] like Figure 16-17 As shown, the second massage body 30' is connected to a hard shell 36', and a third slide groove 364 is formed on the outer wall of the hard shell 36'. The third slide groove 364 extends roughly in a spiral shape in the circumferential direction of the hard shell 36'. A fixing pin 51 is fixedly arranged in the shell 50, and the fixing pin 51 is slidably inserted in the third slide groove 364. When the second massage body 30' is driven to rotate, the fixing pin 51 slides along the third slide groove 364 to make the second massage body 30' telescopically move in the first direction. In other words, the second massage body 30' of this embodiment can also reciprocate in the first direction while rotating, approaching or moving away from the first massage body 20, further enhancing its massage effect.

[0086] The third slide groove 364 is preferably a symmetrical structure, including two spiral segments extending from the second proximal end point A2 to the second distal end point B2 in opposite directions. In this embodiment, the width of the two spirals of the third slide groove 364 in the circumferential direction is half a circle. The second proximal end point A2 and the second distal end point B2 are spaced apart by a certain distance in the axial direction. When the fixing pin 51 slides from the second proximal end point A2 to the second distal end point B2 along the third slide groove 364, the second massage body 30' slides toward the first massage body 20; conversely, when the fixing pin 51 slides from the second distal end point B2 to the second proximal end point A2 along the third slide groove 364, 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 hard shell 36', and the outer wall surface of the hard shell 36' is also provided with a guide groove 366, and the inner wall surface of the output wheel 434' is protrudingly provided with a guide block 438, and the guide block 438 is slidably matched with the guide groove 366, so that the second massage body 30 moves stably and smoothly in the first direction. The guide groove 366 / guide block 438 can be multiple, and are evenly spaced and distributed in the circumferential direction of the hard shell 36' / output wheel 434'. In some embodiments, the guide block 438 can also be provided on the outer wall surface of the hard 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 This is another embodiment of the massage device of the present invention. Different from the aforementioned embodiments, the driving assembly 40" of the massage device 100" of 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 the first driving motor 41a, and rotates around an axis extending along a first direction (such as the X direction) under the drive of the first driving motor 41a. The rotating member 45' is protrudingly provided with a first transmission shaft 454, and the first transmission shaft 454 is eccentrically arranged relative to its rotation axis. When the driving motor 41 is started, the first transmission shaft 454 revolves relative to the rotation axis of the rotating member 45'. The sliding member 46' is provided with a fourth slide groove 466, and the fourth slide groove 466 is in the shape of an elongated strip and extends along a second direction (such as the Y direction), and the second direction is perpendicular to the first direction.

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

[0091] The sliding member 46' is protrudingly provided with a second transmission shaft 468, and the second transmission shaft 468 extends along the first direction. The first swing arm 47a and the second swing arm 47b are rotatably disposed in the housing 50 through a shaft 60. Each swing arm 47a, 47b includes a connecting section 471 and at least one swing section 473, wherein a plug-in slot 475 is formed at the end of the connecting section 471, and the second transmission shaft 468 is movably plugged into the plug-in slot 475 of the connecting section 471 of the two swing arms 47a, 47b.

[0092] When the sliding member 46' reciprocates in the third direction, the ends of the connecting sections 471 of the swing arms 47a and 47b are lifted or pressed down, so that the two swing arms 47a and 47b swing around the shaft 60, driving the first clamping portion 24a and the second clamping portion 24b on the swinging section 473 covered thereon to swing toward or away from each other, thereby achieving pinching massage.

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

[0094] By providing two drive motors 41a and 41b, the movement of the first massage body 20 and the second massage body 30 can be controlled separately, and the user can start only one of the massage bodies 20 and 30 for massage, or start both massage bodies 20 and 30 for massage at the same time, which is more convenient in use. In addition, by providing two drive motors 41a and 42'b, the transmission mechanism between the drive motors 41a and 42b and the massage bodies 20 and 30 can be simplified. For example, in this embodiment, the first transmission mechanism 42' realizes the conversion of rotational motion and linear motion through the cooperation of the eccentrically arranged 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 above two embodiments.

[0095] The two massage bodies of the massage device of the present invention act on the massaged part in different ways at the same time, and the multiple effects are superimposed to give the user a better massage experience. The above is only a preferred specific implementation of the present invention, and the protection scope of the present invention is not limited to the above-listed embodiments. Any simple change or equivalent replacement of the technical solution that can be obviously obtained by any technician familiar with the technical field within the technical scope disclosed in the present invention falls within the protection scope of the present invention.
