Description

Technical Field

[0001] This application belongs to the field of massage device technology, specifically relating to a massage device. Background Technology

[0002] Current waist and abdomen massagers typically offer one or more of the following: vibration massage, electrical pulse massage, and kneading massage. Kneading massage generally involves controlling the motor to rotate 360° in both directions to knead the waist and abdomen. However, because the massage head rotates 360°, the large rotation angle can easily cause excessive stretching of the skin and discomfort. Therefore, it is generally necessary to reduce the speed of the massage head. However, reducing the speed of the massage head can affect the massage effect. Utility Model Content

[0003] The purpose of this application is to provide a massage device that addresses the technical problem of poor massage effect in existing waist and abdomen massagers.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: a massage device, including a housing assembly, a drive mechanism, and multiple massage mechanisms. The drive mechanism has a rotational power output end. Each massage mechanism includes a massage head, a rotating component, a connecting rod, and a swinging component. The rotating component is fixedly connected to the rotational power output end, and the swinging component is rotatably connected to the housing assembly. The massage head is fixedly connected to the swinging component. The connecting rod has a first end and a second end that are arranged opposite to each other. The first end rotates with the rotating component and is eccentrically connected, and the second end rotates with the swinging component and is eccentrically connected. When the rotating component rotates, it can drive the swinging component to swing through the connecting rod, thereby driving the massage head to rotate alternately in the forward and reverse directions. The swing axes of the swinging components of at least two massage mechanisms intersect.

[0005] Furthermore, the drive mechanism includes a driver, a first gear, and a second gear. The first gear is driven to rotate by the driver, and the second gear is the output end of the rotational power. The second gear meshes with the first gear, and the rotating component is fixedly connected to the second gear.

[0006] Furthermore, the housing assembly includes a gearbox, with both the first gear and the second gear disposed inside the gearbox, the massage mechanism located outside the gearbox, and the second gear fixedly connected to a central shaft, which is rotatably connected to the gearbox. One end of the central shaft extends out of the gearbox and is fixedly connected to a rotating component.

[0007] Furthermore, the gearbox includes a first bracket and a second bracket. The first bracket is detachably connected to the second bracket, and the first bracket and the second bracket enclose a mounting cavity. The first gear and the second gear are both disposed in the mounting cavity, and the two ends of the central shaft are rotatably connected to the first bracket and the second bracket, respectively.

[0008] Furthermore, both the first gear and the second gear are bevel gears, and the rotation axis of the second gear is parallel to the swing axis of the swinging component of the massage mechanism connected to the second gear.

[0009] Furthermore, the first end is connected to the rotating part by a ball joint, and the second end is connected to the swinging part by a ball joint. Both the first gear and the second gear are spur gears or helical gears. The rotation axis of the second gear intersects with the swinging axis of the swinging part of the massage mechanism connected to the second gear.

[0010] Furthermore, a first spherical sliding assembly is provided between the first end and the rotating component. The first spherical sliding assembly includes a first outer ring and a first inner ring. The first outer ring is fixedly connected to the first end. The first outer ring has a first inner spherical surface. The first inner ring is disposed inside the first outer ring. The first inner ring has a first outer spherical surface that slides in contact with the first inner spherical surface. The end of the rotating component away from the power output end has a first connecting post. The first inner ring is sleeved on the first connecting post.

[0011] A second spherical sliding assembly is provided between the second end and the swing member. The second spherical sliding assembly includes a second outer ring and a second inner ring. The second outer ring is fixedly connected to the second end. The second outer ring has a second inner spherical surface. The second inner ring is disposed inside the second outer ring. The second inner ring has a second outer spherical surface that slides in contact with the second inner spherical surface. The end of the swing member away from the fixed mechanism has a second connecting post. The second inner ring is sleeved on the second connecting post.

[0012] Furthermore, the housing assembly includes a housing, a receiving cavity is formed inside the housing, the drive mechanism and the connecting rod are at least partially disposed in the receiving cavity, the housing is provided with a through hole communicating with the receiving cavity, and the swing member is at least partially located in the through hole.

[0013] Furthermore, the outer casing has an arc-shaped hole communicating with the through hole on the outer periphery of the through hole. The arc-shaped hole extends circumferentially along the through hole. The swing member includes a base and a protrusion. The base is at least partially located inside the through hole. The base is rotatably connected to the housing assembly. The massage head is fixedly connected to the base. One end of the protrusion is fixedly connected to the base. The other end of the protrusion extends into the arc-shaped hole and is rotatably connected to the second end.

[0014] Furthermore, the housing assembly includes a housing, and the massage device also includes a first strap and a second strap. A receiving cavity is formed inside the housing, and the drive mechanism is at least partially disposed in the receiving cavity. One end of the first strap and one end of the second strap are both connected to the housing, and the other end of the first strap is detachably connected to the other end of the second strap.

[0015] Compared with existing technologies, the beneficial effects of the massage device provided in this application are as follows: During operation, the rotational power output end of the drive mechanism drives the rotating parts of multiple massage mechanisms to rotate. As the rotating parts rotate, they drive the oscillating parts to oscillate within a certain angle range via connecting rods, thereby causing the massage heads to rotate alternately in both directions within that angle range to simulate the effect of hand kneading. Compared to the traditional 360° rotation of massage heads, by controlling the massage heads to rotate alternately in both directions within a smaller angle range, not only is excessive pulling on the skin and causing discomfort, but the rotational speed of the massage heads can also be increased, thus enhancing the massage effect. Furthermore, by making the oscillation axes of at least two massage mechanisms intersect, the rotation axes of the corresponding massage heads can also intersect, better adapting to the natural curve of the waist and abdomen, and allowing a corresponding number of massage heads to simultaneously press against the waist and abdomen, thereby enhancing the massage effect.

[0040] Example 1

[0041] Combination Figure 1 , Figure 2 and Figure 4As shown, this application embodiment provides a massage device, including a housing assembly, a drive mechanism 10, and multiple massage mechanisms 20. The drive mechanism 10 has a rotational power output end. Each massage mechanism 20 includes a massage head 21, a rotating member 22, a connecting rod 23, and a swing member 24. The rotating member 22 is fixedly connected to the rotational power output end, and the swing member 24 is rotatably connected to the housing assembly. The massage head 21 is fixedly connected to the swing member 24. The connecting rod 23 has a first end 231 and a second end 232 that are arranged opposite to each other. The first end 231 is rotatably and eccentrically connected to the rotating member 22, and the second end 232 is rotatably and eccentrically connected to the swing member 24. When the rotating member 22 rotates, it can drive the swing member 24 to swing through the connecting rod 23, thereby driving the massage head 21 to rotate alternately in the forward and reverse directions. The swing axes of the swing members 24 of the two massage mechanisms 20 intersect.

[0042] During operation, the rotational power output of the drive mechanism 10 drives the rotating parts 22 of multiple massage mechanisms 20 to rotate. As the rotating parts 22 rotate, they drive the oscillating parts 24 to oscillate within a certain angle range via the connecting rod 23. This causes the massage heads 21 to rotate alternately in both clockwise and counterclockwise directions within that angle range, simulating the effect of hand kneading. Compared to the traditional 360° rotation of massage heads, controlling the massage heads 21 to rotate alternately in both directions within a smaller angle range not only avoids excessive skin stretching and discomfort but also increases the rotational speed of the massage heads 21, thus enhancing the massage effect. Furthermore, by making the oscillation axes of at least two massage mechanisms 20's oscillating parts 24 form an angle, the rotation axes of the corresponding massage heads 21 intersect, better adapting to the natural curve of the waist and abdomen, and ensuring that multiple massage heads 21 simultaneously press against the waist and abdomen, thereby enhancing the massage effect.

[0043] Figure 1 The diagram shows two massage mechanisms 20, corresponding to two rotary power output ends. The two massage heads 21 can be used to massage the left and right abdomens respectively. In other embodiments, the number of massage mechanisms 20 can be three, four, five, or more; the specific number is not limited. The number of rotary power output ends matches the number of massage mechanisms 20, and multiple rotary power output ends drive the rotating parts 22 of multiple massage mechanisms 20 to rotate. When there are three or more massage mechanisms 20, the swing axes of at least two of the massage mechanisms 20's swing members 24 intersect, allowing the massage heads 21 of the two massage mechanisms 20 to respectively conform to the left and right abdomens. For example, there can be four massage mechanisms 20, arranged in two rows. One row of massage mechanisms 20 conforms to the left abdomen, and the other row conforms to the right abdomen. The swing axes of the swing members 24 of massage mechanisms 20 in different rows intersect, while the swing axes of the swing members 24 of massage mechanisms 20 in the same row can be parallel.

[0044] Specifically, Figure 2 The rotation axis of the left-side rotary power output end is the first axis 31. The left-side rotating component 22 rotates around the first axis 31. The swing axis of the left-side oscillating component 24 is the second axis 32. The left-side oscillating component 24 swings around the second axis 32. The first end 231 of the left-side connecting rod 23 rotates and is eccentrically connected to the left-side rotating component 22. This means that the first end 231 of the left-side connecting rod 23 and the left-side rotating component 22 are both rotatedly connected and eccentrically connected. The eccentric connection means that the first end 231 of the left-side connecting rod 23 is connected to a part of the left-side rotating component 22 that is off-center from the first axis 31; that is, the first end 231 of the left-side connecting rod 23 does not fall on the first axis 31. The second end 232 of the rod 23 is rotatably and eccentrically connected to the left swinging member 24. This means that the second end 232 of the left connecting rod 23 is both rotatably and eccentrically connected to the left swinging member 24. The eccentric connection means that the second end 232 of the left connecting rod 23 is connected to the part of the left swinging member 24 that is off the second axis 32. That is, the second end 232 of the left connecting rod 23 does not fall on the second axis 32. In this way, the continuous rotational motion of the left connecting rod 23 around the first axis 31 can be converted into the swinging motion of the left swinging member 24 around the second axis 32. Its working principle is the same as that of the crank-rocker mechanism. The rotating member 22 is equivalent to the crank, and the swinging member 24 is equivalent to the rocker. Figure 2 The rotation axis of the right-side rotary power output end is the third axis 33. The right-side rotating component 22 rotates around the third axis 33. The swing axis of the right-side oscillating component 24 is the fourth axis 34. The right-side oscillating component 24 swings around the fourth axis 34. The first end 231 of the right-side connecting rod 23 is rotatably and eccentrically connected to the right-side rotating component 22. This means that the first end 231 of the right-side connecting rod 23 and the right-side rotating component 22 are both rotatably and eccentrically connected. The eccentric connection means that the first end 231 of the right-side connecting rod 23 is connected to a part of the right-side rotating component 22 that is off-center from the third axis 33; that is, the first end 231 of the right-side connecting rod 23 does not fall on the third axis 33. The second end 232 of the rod 23 is rotatably and eccentrically connected to the right swing member 24. This means that the second end 232 of the right connecting rod 23 and the right swing member 24 are both rotatably and eccentrically connected. The eccentric connection means that the second end 232 of the right connecting rod 23 is connected to the part of the right swing member 24 that is off the fourth axis 34. That is, the second end 232 of the right connecting rod 23 does not fall on the fourth axis 34. In this way, the continuous rotational motion of the right connecting rod 23 around the third axis 33 can be converted into the swinging motion of the right swing member 24 around the fourth axis 34. Its working principle is the same as that of the crank-rocker mechanism. The rotating member 22 is equivalent to the crank, and the swing member 24 is equivalent to the rocker.

[0045] The angle formed by the swing axes of the two massage mechanisms 20's swing members 24, namely the angle formed by the second axis 32 and the fourth axis 34, can be determined according to the natural curve of the waist and abdomen. Generally, when the angle is within 30°, the two massage heads 21 can make close contact with the waist and abdomen of most people. For example, the angle can be designed to be 24°.

[0046] The swing amplitude of the swing member 24 can be determined according to actual needs. By controlling the swing amplitude of the swing member 24 to 30° or less, the massage head 21 can rotate rapidly in both directions within 30°, thereby applying a shaking effect to the waist and abdominal muscles and enhancing the massage effect on the waist and abdominal muscles. The swing amplitude of the swing member 24 can be adjusted by adjusting the distance from the first end 231 of the connecting rod 23 to the rotation axis of the rotation power output end, or by adjusting the distance from the second end 232 of the connecting rod 23 to the swing axis of the swing member 24.

[0047] Furthermore, combined Figure 2 and Figure 6 As shown, the drive mechanism 10 includes a driver 11, a first gear 12, and a second gear 13. The first gear 12 is driven to rotate by the driver 11, and the second gear 13 is the output end for rotational power. The second gear 13 meshes with the first gear 12, and the rotating component 22 is fixedly connected to the second gear 13. When the driver 11 drives the first gear 12 to rotate, since multiple second gears 13 mesh with the first gear 12, the first gear 12 can simultaneously drive multiple second gears 13 to rotate around their respective rotation axes. The multiple second gears 13 then drive their respective connected rotating components 22, connecting rods 23, swinging components 24, and massage heads 21 to move. That is, only one driver 11 is needed to drive multiple massage heads 21 to move simultaneously, eliminating the need for a separate driver 11 for each massage head 21. This simplifies the device structure, reduces manufacturing costs, and lowers energy consumption. Specifically, the second gear 13 on the left rotates around the first axis 31, and the second gear 13 on the right rotates around the third axis 33.

[0048] Furthermore, such as Figure 2 As shown, the driver 11 can be a motor, which has an output shaft 111. The first gear 12 is fixedly sleeved on the output shaft 111, so that it is driven to rotate by the output shaft 111.

[0049] Furthermore, such as Figure 2As shown, the housing assembly includes a gearbox 14, with the first gear 12 and the second gear 13 both housed within the gearbox 14. The massage mechanism 20 is located outside the gearbox 14. The second gear 13 is fixedly connected to a central shaft 15, which is rotatably connected to the gearbox 14. One end of the central shaft 15 extends outside the gearbox 14 and is fixedly connected to the rotating component 22. When the first gear 12 drives the second gear 13 to rotate, the second gear 13 drives the central shaft 15 to rotate, which in turn drives the rotating component 22 to rotate. By arranging the massage mechanism 20 outside the gearbox 14 and only installing the first gear 12 and the second gear 13 inside the gearbox 14, the assembly accuracy of the first gear 12 and the second gear 13 is improved, reducing vibration and noise during operation. When both the first gear 12 and the second gear 13 are bevel gears, the accuracy of the installation angles of the first gear 12 and the second gear 13 can be further guaranteed. Specifically, the second gear 13 can be integrally formed with the central shaft 15, or it can be mounted on the central shaft 15, with the axis of the central shaft 15 coinciding with the axis of rotation of the second gear 13.

[0050] Furthermore, both the first gear 12 and the second gear 13 are bevel gears, and the rotation axis of the second gear 13 is parallel to the swing axis of the swing member 24 of the massage mechanism 20 connected to the second gear 13, that is... Figure 2 The first axis 31 of the second gear 13 on the left is parallel to the second axis 32 of the left-side oscillating member 24, and the third axis 33 of the second gear 13 on the right is parallel to the fourth axis 34 of the right-side oscillating member 24. Both the first gear 12 and the second gear 13 are bevel gears, which can change the transmission direction, causing the rotation axis of the second gear 13 to be inclined to the rotation axis of the first gear 12. The rotation axis of the second gear 13 is parallel to the oscillation axis of the oscillating member 24 on the same side, thus enabling the oscillation axes of the two massage mechanisms 20's oscillating members 24 to intersect, i.e., the second axis 32 intersects the fourth axis 34. Specifically, the two second gears 13 are of the same specification and are symmetrically arranged about the first gear 12 to ensure normal and stable transmission.

[0051] Furthermore, such as Figure 5 As shown, the gearbox 14 includes a first bracket 141 and a second bracket 142. The first bracket 141 is detachably connected to the second bracket 142, and the first bracket 141 and the second bracket 142 enclose a mounting cavity. The first gear 12 and the second gear 13 are both disposed within the mounting cavity. The two ends of the central shaft 15 are rotatably connected to the first bracket 141 and the second bracket 142, respectively. The detachable connection of the first bracket 141 to the second bracket 142 facilitates the installation and removal of the first gear 12 and the second gear 13. Specifically, the swing member 24 is rotatably connected to the second bracket 142 and is located outside the mounting cavity for easy assembly.

[0052] Furthermore, the first bracket 141 and the second bracket 142 respectively abut against the two sides of the axis of the second gear 13, which can play an axial limiting role for the second gear 13, prevent the second gear 13 from axially shifting, and reduce vibration and noise during operation.

[0053] Furthermore, the first bracket 141 is provided with a first mounting hole, and the second bracket 142 is provided with a second mounting hole. One end of the central shaft 15 rotatably passes through the first mounting hole, and the other end of the central shaft 15 rotatably passes through the second mounting hole. This enables radial positioning of the central shaft 15, thereby achieving radial positioning of the second gear 13, preventing radial displacement of the second gear 13, and reducing vibration and noise during operation. Specifically, the number of first mounting holes and second mounting holes is the same as the number of second gears 13, and multiple central shafts 15 are respectively provided with multiple first mounting holes and multiple second mounting holes.

[0054] Furthermore, such as Figure 7 As shown, one end of the rotating component 22 is provided with a first connecting hole 221, and the other end of the rotating component 22 is provided with a first connecting post 222, as shown. Figure 6 As shown, one end of the central shaft 15 is provided with a first threaded hole 151. The massage device also includes a first threaded fastener, which passes through the first connecting hole 221 and is threadedly connected to the first threaded hole 151, thereby achieving a fixed connection between the rotating part 22 and the central shaft 15. The first end 231 of the connecting rod 23 is rotatably sleeved on the first connecting post 222, thereby achieving a rotatable connection between the connecting rod 23 and the rotating part 22. Of course, in some other embodiments, the first connecting post 222 may not be provided on the rotating part 22, but may be provided on the first end 231 of the connecting rod 23, with the end of the rotating part 22 away from the first connecting hole 221 rotatably sleeved on the first connecting post 222. In addition, in some other embodiments, the central shaft 15 and the rotating part 22 may be integrally formed, or assembled and fixed by other means, such as bonding, snap-fitting, etc.

[0055] In addition, in some other embodiments, the rotating member 22 can also be the first eccentric column. The gearbox 14 is provided with a first clearance hole. The first eccentric column is not fixedly connected to the central shaft 15, but extends into the gearbox 14 through the first clearance hole and is directly fixedly connected to the second gear 13. The connecting rod 23 is rotatably sleeved on the first eccentric column. Since the movement of the first eccentric column is a circular motion around the rotation axis of the second gear 13, the first clearance hole needs to be designed as an annular shape to accommodate the movement trajectory of the first eccentric column.

[0056] Furthermore, such as Figure 2As shown, the housing assembly includes a housing 40, within which a receiving cavity 41 is formed. The drive mechanism 10 and the connecting rod 23 are at least partially disposed within the receiving cavity 41. The housing 40 has a through hole 42 communicating with the receiving cavity 41, and the oscillating member 24 is at least partially located within the through hole 42. Compared to completely inserting the oscillating member 24 into the receiving cavity 41, by having the oscillating member 24 at least partially located within the through hole 42, the space of the receiving cavity 41 can be reduced, thereby reducing the thickness of the housing 40 and making the massage device thinner and lighter, improving portability. Specifically, the massage head 21 is disposed outside the housing 40, and the through hole 42 allows the oscillating member 24 to connect to the massage head 21. The number of through holes 42 is the same as the number of oscillating members 24, with multiple oscillating members 24 located within multiple through holes 42. The fact that the drive mechanism 10 and the connecting rod 23 are at least partially disposed within the accommodating cavity 41 means that the drive mechanism 10 and the connecting rod 23 can be completely placed into the accommodating cavity 41 or partially protrude from the accommodating cavity 41. It is only necessary to open a hole at the corresponding position on the outer shell 40 to satisfy the condition that the drive mechanism 10 and the connecting rod 23 partially protrude from the accommodating cavity 41.

[0057] Furthermore, such as Figure 3 As shown, the outer casing 40 has an arc-shaped hole 43 communicating with the through hole 42 on the outer periphery of the through hole 42. The arc-shaped hole 43 extends circumferentially along the through hole 42. The swing member 24 includes a base 241 and a protrusion 242. The base 241 is at least partially located in the through hole 42. The base 241 is rotatably connected to the casing assembly. The massage head 21 is fixedly connected to the base 241. One end of the protrusion 242 is fixedly connected to the base 241. The other end of the protrusion 242 extends into the arc-shaped hole 43 and is rotatably connected to the end of the connecting rod 23 away from the rotating member 22. When the rotating member 22 rotates, it drives the protrusion 242 of the swing member 24 to swing around the swing axis of the swing member 24 in the arc-shaped hole 43 via the connecting rod 23. The length of the arc-shaped hole 43 corresponds to the swing amplitude of the protrusion 242. When the protrusion 242 swings, it drives the base 241 to rotate alternately in both directions around the swing axis, thereby driving the massage head 21 to rotate alternately in both directions. Specifically, in the figure, the base 241 of the swing member 24 on the left rotates alternately in both directions around the second axis 32, and the protrusion 242 of the swing member 24 on the left swings around the second axis 32. The base 241 of the swing member 24 on the right rotates alternately in both directions around the fourth axis 34, and the protrusion 242 of the swing member 24 on the right swings around the fourth axis 34.

[0058] Furthermore, such as Figure 8As shown, a second connecting post 2421 is provided on the protrusion 242, and the second end 232 of the connecting rod 23 is rotatably sleeved on the second connecting post 2421, thereby realizing the rotatable connection between the swing member 24 and the connecting rod 23. A third connecting post 2411 is provided on the base 241, and the axis of the third connecting post 2411 is the swing axis of the swing member 24. The third connecting post 2411 is rotatably connected to the housing assembly, thereby realizing the rotatable connection between the swing member 24 and the housing assembly. Of course, in some other embodiments, the third connecting post 2411 may not be provided on the base 241, but may be provided on the housing assembly. In this case, the base 241 is rotatably sleeved on the third connecting post 2411. Alternatively, the second connecting post 2421 may not be provided on the protrusion 242, but may be provided on the second end 232 of the connecting rod 23. In this case, the protrusion 242 is rotatably sleeved on the second connecting post 2421.

[0059] In other embodiments, the protrusion 242 and the arc-shaped hole 43 can be omitted, and a second eccentric post can be provided on the base 241. The second eccentric post is offset from the swing axis of the swing member 24, and the second end 232 of the connecting rod 23 is rotatably sleeved on the second eccentric post. Compared with the second eccentric post, the protrusion 242 can increase the distance from the connection point between the connecting rod 23 and the swing member 24 to the swing axis of the swing member 24, that is, increase the lever arm of the swing member 24, thereby helping to reduce the energy consumption of the drive mechanism 10.

[0060] Furthermore, the third connecting post 2411 of the swing member 24 is rotatably connected to the gearbox 14, and the gearbox 14 is fixedly connected to the housing 40. Of course, in some other embodiments, the swing member 24 may also be rotatably connected to the housing 40.

[0061] Furthermore, combined Figure 2 and Figure 5 As shown, the second bracket 142 of the gearbox 14 is provided with a mounting groove, and an annular damping rubber 50 is provided in the mounting groove. The third connecting column 2411 is rotatably inserted into the inner hole of the annular damping rubber 50, which can play a damping role, improve the stability of the swinging part 24 during movement, and reduce vibration and noise.

[0062] Furthermore, such as Figure 1As shown, the massage device also includes a first strap 60 and a second strap 70. One end of the first strap 60 and one end of the second strap 70 are both connected to the outer casing 40, and the other end of the first strap 60 is detachably connected to the other end of the second strap 70. In use, by connecting the end of the first strap 60 away from the outer casing 40 to the end of the second strap 70 away from the outer casing 40, the massage head 21 is ensured to be in close contact with the waist and abdomen, thus guaranteeing the massage effect. The connection method between the end of the first strap 60 away from the outer casing 40 and the end of the second strap 70 away from the outer casing 40 is not limited; it can be achieved through Velcro, snap fasteners, or magnetic attachment.

[0063] Furthermore, such as Figure 2 As shown, the massage device also includes a first strap cover 80 and a second strap cover 90, which are respectively disposed at opposite ends of the outer casing 40. One end of the first strap 60 is fixedly connected to the first strap cover 80, and one end of the second strap 70 is fixedly connected to the second strap cover 90. Specifically, the first strap 60 can be glued or wrapped around the first strap cover 80, and the second strap 70 can be glued or wrapped around the second strap cover 90. The first strap cover 80 and the second strap cover 90 can be fixed to the outer casing 40 by screws.

[0064] Furthermore, such as Figure 5 As shown, the outer casing 40 includes a front shell 44 and a bottom shell 45. The front shell 44 is detachably connected to the bottom shell 45, and the front shell 44 and the bottom shell 45 together form an accommodating cavity 41. The detachable connection of the front shell 44 to the bottom shell 45 facilitates the installation and removal of accessories such as the drive mechanism 10. The connection method between the front shell 44 and the bottom shell 45 is not limited; it can be a snap-fit ​​connection or a screw connection. Specifically, a through hole 42 is formed in the bottom shell 45, and the massage head 21 is located on the bottom shell 45.

[0065] Furthermore, combined Figure 2 and Figure 5 As shown, the massage device also includes a battery 100, which is disposed within the accommodating cavity 41 and electrically connected to the drive mechanism 10, providing power to the drive mechanism 10. Specifically, the battery 100 is fixedly mounted on the side of the faceplate 44 facing the accommodating cavity 41.

[0066] Furthermore, such as Figure 5 As shown, the massage device also includes a battery holder 110, which is fixedly connected to the face shell 44 by screws, thereby pressing and fixing the battery 100 onto the face shell 44.

[0067] Furthermore, combined Figure 2 and Figure 5As shown, the massage device also includes a main control board 120, which is fixedly installed on the side of the faceplate 44 facing the receiving cavity 41. The main control board 120 is electrically connected to the drive mechanism 10. Buttons are provided on the main control board 120, and mounting holes are provided on the faceplate 44 corresponding to the button positions, with the buttons positioned within the mounting holes. Specifically, the buttons include a power button 130 and a mode button 140. The power button 130 is used to control the power switch of the massage device, and the mode button 140 is used to switch the operating mode of the massage device.

[0068] Furthermore, combined Figure 2 and Figure 5 As shown, the massage device also includes a speaker 150, which is disposed within the receiving cavity 41 and can be used to broadcast voice messages. Specifically, the speaker 150 is fixedly installed on the side of the faceplate 44 facing the receiving cavity 41.

[0069] Furthermore, combined Figure 2 and Figure 5 As shown, the massage head 21 includes a massage head body 211, a massage head cover 212, and a massage head base 213. The massage head base 213 has a second connecting hole, and the base 241 of the swing member 24 has a second threaded hole. The massage device also includes a second threaded fastener, which passes through the second connecting hole and is then threadedly connected to the second threaded hole, thereby fixing the massage head base 213 to the swing member 24. The massage head body 211 has a fixing groove, and the massage head base 213 is inserted into the fixing groove to fix the massage head body 211 and the massage head base 213. The massage head cover 212 is provided with a buckle, and the massage head cover 212 is fastened to the massage head base 213 through the buckle. The massage head cover 212 is used to cover the second threaded fastener, preventing the second threaded fastener from being exposed and improving aesthetics. During operation, the swing member 24 drives the massage head base 213 to rotate, and the massage head base 213 then drives the massage head body 211 to rotate, thereby performing a rotary massage on the waist and abdomen through the massage head body 211.

[0070] Example 2

[0071] Combination Figure 9 , Figure 10 and Figure 11 As shown, this embodiment provides another massage device. The massage device provided in this embodiment, together with the massage device in Embodiment 1, includes a housing 40, a rotating component 22, a connecting rod 23, a swing component 24, a driver 11, a first gear 12, a second gear 13, a central shaft 15, a first strap 60, a second strap 70, a first strap cover 80, a second strap cover 90, a battery 100, a battery fixing component 110, a main control board 120, a power button 130, a mode button 140, a speaker 150, and other structures.

[0072] The massage device in this embodiment differs from the massage device in Embodiment 1 in that: the first end 231 of the connecting rod 23 is connected to the rotating member 22 by a ball joint, and the second end 232 of the connecting rod 23 is connected to the swing member 24 by a ball joint. By connecting the first end 231 and the second end 232 of the connecting rod 23 to the rotating member 22 and the swing member 24 via ball joints, on the one hand, the connecting rod 23 is rotatably connected to the rotating member 22 and to the swing member 24, respectively. This allows the rotating member 22 to swing the swing member 24 within a certain angle range via the connecting rod 23 when rotating, thereby causing the massage head 21 to rotate alternately in both directions within that angle range, simulating the effect of hand kneading. Compared to the traditional 360° rotation of the massage head, by controlling the massage head 21 to repeatedly rotate in both directions within a smaller angle range, it not only avoids excessive pulling on the skin and causing discomfort, but also increases the rotation speed of the massage head 21, thereby enhancing the massage effect. On the other hand, it can change the direction of power transmission and adjust the angle of the connecting rod 23 and the swing member 24 according to actual needs, so that the swing axes of the swing members 24 of at least two massage mechanisms 20 intersect, thereby causing the rotation axes of the corresponding massage heads 21 to intersect, so as to better adapt to the natural curve of the waist and abdomen, and satisfy the requirement that multiple massage heads 21 simultaneously press against the waist and abdomen, thereby enhancing the massage effect.

[0073] Furthermore, both the first gear 12 and the second gear 13 are spur gears or helical gears, and the rotation axis of the second gear 13 intersects with the swing axis of the swing member 24 of the massage mechanism 20 connected to the second gear 13, that is... Figure 9 The first axis 31 of the second gear 13 on the left intersects with the second axis 32 of the left swing member 24, and the third axis 33 of the second gear 13 on the right intersects with the fourth axis 34 of the right swing member 24. In the massage device of Embodiment 1, both the first gear 12 and the second gear 13 are bevel gears, and the rotation axis of the second gear 13 intersects with the rotation axis of the first gear 12 to change the direction of power transmission. At the same time, the swing axis of the swing member 24 needs to be parallel to the rotation axis of the second gear 13. However, in this embodiment, the massage device can change the direction of power transmission by connecting the two ends of the connecting rod 23 to the rotating member 22 and the swing member 24 by ball joints, respectively. Therefore, the first gear 12 and the second gear 13 do not need to be bevel gears. Instead, spur gears or helical gears with simpler structures and lower manufacturing costs can be used, so that the rotation axis of the second gear 13 is parallel to the rotation axis of the first gear 12, while the rotation axis of the swing member 24 can intersect with the rotation axis of the second gear 13.

[0074] Furthermore, a first spherical sliding assembly 160 is provided between the first end 231 of the connecting rod 23 and the rotating member 22. The first spherical sliding assembly 160 includes a first outer ring 161 and a first inner ring 162. The first outer ring 161 is fixedly connected to the first end 231 of the connecting rod 23. The first outer ring 161 has a first inner spherical surface. The first inner ring 162 is disposed inside the first outer ring 161. The first inner ring 162 has a first outer spherical surface that slides in contact with the first inner spherical surface. The end of the rotating member 22 away from the power output end has a first connecting post 222. The first inner ring 162 is sleeved on the first connecting post 222. Above; a second spherical sliding assembly 170 is provided between the second end 232 of the connecting rod 23 and the swing member 24. The second spherical sliding assembly 170 includes a second outer ring 171 and a second inner ring 172. The second outer ring 171 is fixedly connected to the second end 232 of the connecting rod 23. The second outer ring 171 has a second inner spherical surface. The second inner ring 172 is disposed inside the second outer ring 171. The second inner ring 172 has a second outer spherical surface that slides in contact with the second inner spherical surface. The swing member 24 has a second connecting post 2421 at the end away from the housing assembly. The second inner ring 172 is sleeved on the second connecting post 2421. When the rotating component 22 rotates, the first connecting post 222, located at the end of the rotating component 22 furthest from the power output end, will rotate around the rotation axis of the power output end. This will cause the first inner ring 162 and the first outer ring 161, which are sleeved on the first connecting post 222, to rotate. The first outer ring 161 then drives the connecting rod 23 to move, and the connecting rod 23 then drives the second outer ring 171 and the second inner ring 172 to move. The second inner ring 172 then drives the oscillating component 24 to oscillate around the oscillation axis through the second connecting post 2421. Since the rotation axis of the power output end intersects with the oscillation axis of the oscillating component 24, the angle between the line connecting the first connecting post 222 and the second connecting post 2421 will continuously change during the rotation of the first connecting post 222 around the rotation axis of the power output end and the rotation of the second connecting post 2421 around the oscillation axis of the oscillating component 24. This requires the angle of the connecting rod 23 to change. To allow the angle of the connecting rod 23 to change, a first spherical sliding assembly 160 connects the first connecting post 222 and the first end 231 of the connecting rod 23, and a second spherical sliding assembly 170 connects the second connecting post 2421 and the second end 232 of the connecting rod 23. For the first spherical sliding assembly 160, under the sliding engagement of the first inner spherical surface and the first outer spherical surface, the first outer ring 161 can rotate freely in multiple directions relative to the first inner ring 162. For the second spherical sliding assembly 170, under the sliding engagement of the second inner spherical surface and the second outer spherical surface, the second outer ring 171 can rotate freely in multiple directions relative to the second inner ring 172. The first end 231 and the second end 232 of the connecting rod 23 are fixed to the first outer ring 161 and the second outer ring 171, respectively, thereby enabling the change of the angle of the connecting rod 23.

[0075] Specifically, the first outer ring 161 and the first inner ring 162 form a spherical sliding bearing, and the second outer ring 171 and the second inner ring 172 also form a spherical sliding bearing, which is also known as a spherical plain bearing.

[0076] The rest of this embodiment can be the same as that in Embodiment 1. Features not explained in this embodiment can be explained using the methods in Embodiment 1, and will not be repeated here.

[0077] It should be noted that the above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
