Description

Massage mechanism and massage device

[0001] This application claims priority to Chinese patent application No. 202322636825.X filed on September 27, 2023, and all disclosed contents of that application are incorporated herein by reference. Technical Field

[0002] The present application relates to the technical field of massagers, and in particular to a massage mechanism and a massage device used in a massager. Background Art

[0003] The neck massager is equipped with several massage heads. The massage head brackets of the massage heads are connected to a transmission mechanism. When the drive mechanism is in operation, the transmission mechanism drives the massage head brackets to move, and the massage heads follow the movement to achieve the massage function. In order to enhance the massage effect, a percussion drive mechanism is also provided. The percussion drive mechanism is mounted on one side of the massage head bracket, and the output end of the percussion drive mechanism is hinged to the massage head bracket. The hinge point between the output end and the massage head bracket is between the pivot end of the massage head bracket and the massage head, which affects the movement amplitude of the massage head bracket along the pivot axis. Specifically, because the output end of the percussion drive mechanism is connected to the middle of the massage head bracket, it affects the movement amplitude of the massage head bracket relative to its pivot axis, and also affects the vibration percussion amplitude of the massage head bracket along the circumferential direction of the pivot axis. As a result, the percussion massage range of the massage head is limited, the massage range is small, and the performance needs to be improved.

[0058] The following further describes the specific embodiments of the present application with reference to the accompanying drawings. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively.

[0059] As shown in FIG. 1-4 in combination with FIG. 14 , a massage mechanism provided in one embodiment of the present application includes a massage component 1 and a knocking drive component 2 for driving the massage component 1 to perform knocking motion.

[0060] The massage component 1 comprises an assembly ring 11, a connecting arm 12 and a massage head 13 which are connected in sequence. The connecting arm 12 is in the shape of an elongated strip.

[0061] The knocking drive member 2 includes a hinge base 21 for connecting to the eccentric rotating member 71 and a hinge arm 22 hinged to the hinge base 21 .

[0062] The knocking drive member 2 and the connecting arm 12 are located on the same side of the assembly ring 11 , and the knocking drive member 2 is located below the connecting arm 12 .

[0063] A hinge seat 14 is provided at the lower half of the assembly ring 11 , and one end of the hinge arm 22 is hinged to the hinge seat 14 .

[0064] The massage mechanism provided in this application is a component of a massager (e.g., a shoulder and neck massager). The massage mechanism includes a massage component 1 and a knock drive component 2.

[0065] The massage component 1 is assembled with the pivot axis of the massager and can move relative to the pivot axis.

[0066] The knocking drive member 2 is connected to the drive transmission mechanism in the massager to drive the massage member 1 to swing or vibrate back and forth in the circumferential direction relative to its pivot axis, thereby realizing the knocking motion and further realizing the knocking massage function.

[0067] As required, the pivot axis can be configured as a fixed axis. In this case, the massage component 1 only has a percussion massage function.

[0068] As required, the pivot shaft can be configured as a rotating shaft, which can be driven to rotate by a driving mechanism in the massager.

[0069] The massage component 1 and the rotating shaft have the following two assembly methods:

[0070] In one embodiment, the massage member 1 can reciprocate or vibrate within a certain angle along the circumferential direction relative to the rotating shaft. The massage member 1 has a pressing massage function and also has a tapping massage function at all times. In this embodiment, the tapping frequency of the massage member 1 driven by the tapping drive member 2 is faster than the reciprocating vibration frequency of the massage member 1 driven by the rotating shaft, and the tapping amplitude of the massage member 1 driven by the tapping drive member 2 is smaller than the vibration amplitude of the massage member 1 driven by the rotating shaft.

[0071] In another embodiment, the massage component 1 can swing back and forth in a certain range along the axial direction relative to the rotation axis. The massage component 1 has a pinching or kneading massage function, and also has a tapping massage function at any time.

[0072] The circumferential direction mentioned in this application refers to the direction along the circumference.

[0073] The present application is mainly to optimize the assembly method of the knocking drive component 2 and the massage component 1, and to minimize the impact on the range of movement of the massage component 1.

[0074] The massage assembly 1 comprises a mounting ring 11, a connecting arm 12, and a massage head 13, which are integrally connected. The connecting arm 12 is elongated and extends in a predetermined direction. The mounting ring 11 is located at the pivoting or connecting end of the connecting arm 12, while the massage head 13 is located at the free end or distal end of the connecting arm 12. The mounting ring 11 is designed to mate with a pivot shaft or a pivoting member on the pivot shaft. The massage head 13 can be either a fixed or rolling massage head, providing a massage to the user.

[0075] The percussion drive member 2 includes a hinge base 21 and a hinge arm 22. One end of the hinge arm 22 is hingedly connected to the hinge base 21, and the other end is hingedly connected to the assembly ring 11. The hinge base 21 is configured to be sleeved onto the eccentric rotating member 71. When the eccentric rotating member 71 is driven to rotate, the hinge base 21 is driven to vibrate or swing. In turn, the hinge arm 22 pushes and pulls the assembly ring 11 back and forth, causing the massage member 1 to vibrate reciprocally along the circumferential direction relative to its pivot axis, achieving percussion massage.

[0076] Specifically, the percussion drive member 2 and the connecting arm 12 are located on the same side of the assembly ring 11, with the hinge arm 22 and hinge seat 21 both located below the connecting arm 12. The lower half of the assembly ring 11 is provided with a hinge seat 14, to which one end of the hinge arm 22 is hingedly connected. The hinge arm 22 is hingedly connected to the massage member 1 at the pivot end of the connecting arm 12, no longer directly articulated to the connecting arm 12. This reduces restrictions on the movement of the connecting arm 12, increases the circumferential or axial range of motion of the connecting arm 12 relative to its pivot axis, and accordingly, increases the range of motion of the massage head 13, increasing the massage area and enhancing the massage effect.

[0077] In one embodiment, as shown in FIG. 4 , the central angle α between the hinge base 14 and the massage head 13 is an obtuse angle.

[0078] Central angle α is the angle between the extension direction of massage head 13 relative to the center of mounting ring 11 and the extension direction of hinged seat 14 relative to the center of mounting ring 11. This angle is obtuse, so hinged seat 14 does not extend toward massage head 13 or connecting arm 12. This prevents hinged seat 14 from being too close to the driving member 2 due to a too small central angle, which would reduce the space for the transmission connection and make installation difficult.

[0079] The central angle α is an obtuse angle, which makes the space between the massage head 13 / connecting arm 12 and the hinge arm 22 relatively large to avoid interference.

[0080] In one embodiment, as shown in FIG4 , the central angle is between 95° and 125° to avoid the transmission chain between the knocking drive member 2 and the hinge seat 14 being too long due to the central angle being too large, thereby affecting the stability of the transmission connection.

[0081] In one embodiment, as shown in FIG. 1-4 and FIG. 7 , the connecting arm 12 includes a long arm section 120 and a curved arm section 121 connected to the long arm section 120 and extending upwardly in a curved manner. The massage head 13 is connected to the upper end of the curved arm section 121 .

[0082] In this embodiment, the long rod-shaped or long strip-shaped connecting arm 12 has a long arm section 120 and a curved arm section 121. The long arm section 120 extends roughly straight, and the curved arm section 121 is integrally connected to the front end of the long arm section 120 and extends upward at an angle, which is conducive to making the massage head 13 fit better with the human body and improving the massage effect.

[0083] The curvature, inclination angle, length, etc. of the curved arm section 121 can be set as needed.

[0084] In one embodiment, as shown in FIG4 , the hinge arm 22 and the long arm section 120 are substantially parallel and spaced apart from each other. The hinge arm 22 extends from the hinge base 21 toward the hinge base 14 , and the long arm section 120 extends from the assembly ring 11 away from the hinge base 14 .

[0085] In this embodiment, when the connecting arm 12 is in the initial state or initial position, the hinge arm 22 is roughly parallel to the long arm section 120, so that the setting length of the connecting arm 12 is increased by setting them roughly parallel and spaced within a limited space, so that the massage head 13 on the connecting arm 12 has a larger range of movement.

[0086] In one embodiment, as shown in Figures 2-3 and 5-10, the end of the hinge arm 22 connected to the hinge seat 14 has a hinge ball head 221, and the hinge seat 14 has a ball head receiving groove 143, and the hinge ball head 221 can be pivotally assembled in the ball head receiving groove 143.

[0087] In this embodiment, the hinge arm 22 and the hinge seat 14 utilize a ball-jointed structure, resulting in a stable structure and flexible movement. A hinge ball 221 is integrally formed at the end of the hinge arm 22. A ball-receiving slot 143 is provided on the side of the hinge seat 14 facing the hinge arm 22. The hinge ball 221 fits into the slot 143, which acts like a ball socket. The hinge ball 221 can move widely within the slot 143, providing a relatively large range of movement between the hinge arm 22 and the hinge seat 14, further minimizing any impact on the movement of the massage member 1.

[0088] In one embodiment, as shown in FIG. 5-8 , the hinge seat 14 includes a fixing plate 141 integrally connected to the assembly ring 11 and a cover plate 142 detachably connected to the fixing plate 141 .

[0089] The fixing plate 141 and the cover plate 142 are respectively provided with a groove 1431 , and the two grooves 1431 are connected to form a ball head receiving groove 143 .

[0090] In this embodiment, the hinge base 14 includes a fixing plate 141 and a cover plate 142. The fixing plate 141 is integrally mounted on the bottom of the assembly ring 11, and the cover plate 142 is connected to the fixing plate 141 via pins. The facing surfaces of the fixing plate 141 and the cover plate 142 are each provided with a groove 1431, each groove 1431 representing one half of a ball-receiving slot 143. After the cover plate 142 is connected to the fixing plate 141, the two grooves 1431 mate to form the ball-receiving slot 143, facilitating the installation of the hinge ball 221.

[0091] When installing the hinge ball head 221 , first disassemble the cover plate 142 , then put the hinge ball head 221 into the groove 1431 of the fixing plate 141 , and finally connect and fix the cover plate 142 and the fixing plate 141 .

[0092] In one embodiment, as shown in Figure 10, the hinge base 21 includes an annular housing 211 and an end cap 212. A second bearing 23 is mounted in the annular housing 211 for assembly with the eccentric rotating member 71. The annular housing 211 has two lugs 213 on the side facing the hinge arm 22. The hinge arm 22 has a flat end 222 mounted between the two lugs 213 via a rotating shaft. The hinge arm 22 can swing left and right relative to the hinge base 21 to adapt to the swinging motion of the hinge base 21.

[0093] In one embodiment, as shown in FIG. 1-2 , FIG. 6 - FIG. 8 and FIG. 13 , the massage mechanism includes a swing driving component 3 for driving the massage component 1 to swing.

[0094] The swing drive member 3 has a fitting hole 30 for fitting with the rotation shaft.

[0095] The swing driving member 3 is pivotally mounted in the mounting ring 11 and can drive the mounting ring 11 to swing back and forth along the circumferential direction or the axial direction.

[0096] In this embodiment, the assembly ring 11 is provided with a swing driving member 3 , which is rotatable relative to the assembly ring 11 and configured to drive the assembly ring 11 to swing back and forth circumferentially or axially relative to its pivot axis.

[0097] The swing drive member 3 is provided with a through assembly hole 30 for a pivot shaft to pass through and connect. The pivot shaft (for example, the first pivot shaft 6 in FIG14 ) can drive the swing drive member 3 to rotate, and the rotating swing drive member 3 drives the assembly ring 11 to swing.

[0098] The assembly hole 30 is preferably a non-circular or elliptical special-shaped hole to facilitate torque transmission.

[0099] There are two swing modes of the assembly ring 11:

[0100] One method is that the assembly ring 11 swings back and forth within a certain range along the circumferential direction relative to the pivot axis, which can also be called reciprocating vibration, to achieve a pressing massage function. For example, an eccentric wheel is used to drive the assembly ring 11 to swing or vibrate along the circumferential direction. As mentioned above, the massage component 1 with a pressing massage function is also driven by the knocking drive component 2. Therefore, the massage component 1 has a knocking massage function at any time to improve the effect of the pressing massage. In this method, the knocking frequency of the massage component 1 driven by the knocking drive component 2 is faster than the reciprocating vibration frequency of the massage component 1 driven by the rotating shaft, and the knocking amplitude of the massage component 1 driven by the knocking drive component 2 is smaller than the vibration amplitude of the massage component 1 driven by the rotating shaft. The following effect will be produced during massage: when the massage head is pressing on the human body and has not yet left, the user will also feel a secondary force massage due to the action of the knocking drive component 2, which is similar to knocking once or several times, and the massage effect is better.

[0101] Another approach involves reciprocating the axial swing of the assembly ring 11 within a certain range relative to the pivot axis, also known as reciprocating vibration, to achieve a pinching or kneading massage function. For example, a deflected column could be used to drive the assembly ring 11 to axially swing or vibrate. Similarly, the massage member 1, which performs the pinching or kneading massage function, is also driven by the percussion drive member 2. Thus, the massage member 1 always performs the percussion massage function, enhancing the pinching or kneading massage effect. After the massage head 13 acts on the body, the user also experiences a secondary force massage, similar to one or more taps, resulting in a more effective massage.

[0102] In one embodiment, as shown in FIG. 13 , the swing driving member 3 includes an eccentric driving wheel 32 for driving the assembly ring 11 to swing back and forth along the circumferential direction, and the assembly hole 30 is provided on one side of the center of the eccentric driving wheel 32 .

[0103] In this embodiment, the swing drive member 3 uses an eccentric drive wheel 32, and the assembly hole 30 is eccentrically arranged on the eccentric drive wheel 32. The assembly ring 11 is mounted on the eccentric drive wheel 32. When the eccentric drive wheel 32 is rotated by the pivot shaft, the eccentric drive wheel 32 causes the assembly ring 11 to swing in a circumferential direction, thereby driving the entire massage member 1 to swing approximately up and down, thereby achieving a pressing massage.

[0104] In one embodiment, as shown in FIG. 1-2 , FIG. 6 - FIG. 8 and FIG. 11 - 12 , the swing driving member 3 includes a deflected driving body 31 for driving the assembly ring 11 to swing back and forth along the axial direction.

[0105] The assembly hole 30 passes through the skew driving body 31 . The skew driving body 31 includes a column portion 311 that cooperates with the assembly ring 11 . A non-zero angle is formed between the axis of the column portion 311 and the axis of the assembly hole 30 .

[0106] In this embodiment, the swing driving member 3 adopts a deflected driving body 31 for driving the assembly ring 11 to swing approximately left and right.

[0107] The skew drive body 31 has a cylindrical portion 311, and the mounting hole 30 extends through the skew drive body 31. However, the axis AA' of the mounting hole 30 is not parallel to the axis BB' of the cylindrical portion 311, but rather forms an acute angle therebetween. Consequently, the cylindrical surface of the cylindrical portion 311 is tilted relative to the axis AA'. When the skew drive body 31 is rotated by the pivot shaft, it rotates about the axis AA'. The cylindrical surface, tilted relative to the axis AA', acts on the mounting ring 11 to cause it to swing roughly left and right, allowing the massage head 13 to achieve a pinching or kneading massage function.

[0108] In one embodiment, as shown in Figures 6, 8, and 11-12, one end of the column portion 311 is connected to a limiting boss 312, and a limiting ring 33 is mounted on the column portion 311. The mounting ring 11 is mounted on the column portion 311 via the first bearing 4, and the inner ring of the first bearing 4 is mounted between the limiting boss 312 and the limiting ring 33.

[0109] In this embodiment, the mounting ring 11 is mounted on the cylindrical portion 311 via a first bearing 4. The first bearing 4 maintains the stability of the mounting ring 11 as it moves about the cylindrical portion 311. Because the pivot shaft must rotate at a relatively high speed to cause the mounting ring 11 to vibrate or strike, the placement of the first bearing 4 between the mounting ring 11 and the cylindrical portion 311 reduces wear during relatively high-speed rotation.

[0110] A limiting boss 312 is integrally provided at the outer end of the column portion 311, and a slot 313 is provided at the inner end. A limiting ring 33 is installed in the slot 313, and the first bearing 4 is assembled between the limiting boss 312 and the limiting ring 33. Specifically, the inner ring of the first bearing 4 is transferred between the limiting boss 312 and the limiting ring 33, and the inner ring of the first bearing 4 is axially limited by the limiting boss 312 and the limiting ring 33.

[0111] In one embodiment, as shown in FIG. 7-8 , the massage component 1 further includes a pressing plate 15 . The pressing plate 15 is connected to one side of the assembly ring 11 , and a limiting portion 111 is formed on the other side of the assembly ring 11 .

[0112] The outer ring of the first bearing 4 is assembled between the pressure plate 15 and the limiting portion 111 .

[0113] In this embodiment, a pressure plate 15 is mounted on the outside of the mounting ring 11. The pressure plate 15 has a pressure plate through hole 151 for the swing drive member 3 to pass through. A limiting portion 111 is formed on the inside of the mounting ring 11. The limiting portion 111 can be a circle of limiting flanges.

[0114] The first bearing 4 is assembled between the pressure plate 15 and the limiting portion 111 . Specifically, the outer ring of the first bearing 4 is assembled between the pressure plate 15 and the limiting portion 111 , and the outer ring of the first bearing 4 is axially limited by the pressure plate 15 and the limiting portion 111 .

[0115] As shown in Figures 14-16, an embodiment of the present application provides a massage device, which includes a first pivot shaft 6, a second pivot shaft 7 arranged parallel to the first pivot shaft 6, and the massage mechanism described in any of the aforementioned embodiments.

[0116] The mounting ring 11 is in driving connection with the first pivot shaft 6 .

[0117] An eccentric rotating member 71 is provided on the second pivot shaft 7 . The hinge base 21 is sleeved on the eccentric rotating member 71 , and the eccentric rotating member 71 is capable of rotating relative to the hinge base 21 .

The assembly ring 11 of the massage member 1 is mounted on the end of the first pivot shaft 6. An eccentric rotating member 71 is provided at the end of the second pivot shaft 7. The hinge base 21 of the percussion drive member 2 is sleeved on the eccentric rotating member 71, and the eccentric rotating member 71 is rotatable relative to the hinge base 21.

[0121] The first pivot shaft 6 can be a fixed shaft as required, and the massage member 1 only has a tapping massage function. The first pivot shaft 6 can also be a rotating shaft and equipped with a swing drive member 3. In this case, the massage member 1 has the aforementioned pressing massage function + tapping massage function, or a pinching / kneading massage function + tapping massage function.

[0122] The second pivot shaft 7 needs to drive the eccentric rotating member 71 to rotate, so the second pivot shaft 7 is a rotation axis.

[0123] When the first pivot shaft 6 and the second pivot shaft 7 are both rotation shafts, the first pivot shaft 6 and the second pivot shaft 7 may be driven by different driving mechanisms or may share a set of driving mechanisms.

[0124] The eccentric rotating part 71 can be an eccentric wheel or an eccentric shaft. When the eccentric rotating part 71 rotates, it will drive the hinge seat 21 to swing along the circumferential direction, and then push and pull the assembly ring 11 through the hinge arm 22. The assembly ring 11 will rotate back and forth, swing or vibrate relative to the pivot axis to drive the massage component 1 to realize the tapping massage function.

[0125] Preferably, the end of the first pivot shaft 6 has a special-shaped plug-in end 61 with a non-circular or elliptical cross-section, so as to be assembled with the special-shaped assembly hole 30 of the swing drive member 3 to facilitate torque transmission.

[0126] As shown in FIG. 16 , one end of the column portion 311 of the skew driving body 31 may be connected to the first pivot shaft 6 via a snap ring.

[0127] As shown in FIG. 14 and FIG. 16 , a decorative cover 5 may be installed on the outer side of the deflection driving body 31 for decoration and protection.

[0128] In one embodiment, as shown in FIG14 , a massage mechanism is respectively installed at both ends of the first pivot shaft 6 and the second pivot shaft 7 , which is suitable for neck massage. The two massage mechanisms are located on both sides of the user's neck to massage the shoulders and neck respectively.

[0129] In one embodiment, as shown in Figures 17-18, the eccentric rotating member 71 includes an eccentric shaft 711, which is disposed at the end of the second pivot shaft 7 and on one side of the axis of the second pivot shaft 7. The hinge base 21 is pivotally sleeved on the eccentric shaft 711.

[0130] In this embodiment, an eccentric shaft 711 is integrally provided at the end of the second pivot shaft 7 , and the hinge seat 21 is pivotally sleeved on the eccentric shaft 711 . The eccentric drive structure is simple, small in size, and easy to assemble.

[0131] In one embodiment, as shown in Figure 18 , the hinge base 21 is mounted on the eccentric shaft 711 via a second bearing 23. The second bearing 23 maintains the stability of the hinge base 21 as it moves about the eccentric shaft 711. Because the eccentric shaft 711 rotates at a high speed, causing the hinge base 21 to vibrate, the provision of the second bearing 23 between the hinge base 21 and the eccentric shaft 711 reduces wear during relatively high-speed rotation.

[0132] In one embodiment, as shown in FIG17 , an eccentric shaft 711 is provided at each end of the second pivot shaft 7 , and the two eccentric shafts 711 are located on opposite sides of the axis of the second pivot shaft 7 . The two sets of massage components 1 at both ends do not strike the user synchronously when striking, thereby reducing the user's pain.

[0133] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0134] The above are only the principles and preferred embodiments of the present application. It should be noted that, for those skilled in the art, on the basis of the principles of the present application, several other modifications can be made, which should also be considered as the scope of protection of the present application.
