Detailed Implementation

[0041] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] Example 1

[0044] Please refer to Figures 1-11 This application provides a massage facility, comprising:

[0045] A housing 1, a drive mechanism 2 is installed on the outside of the housing 1, and a transmission mechanism is provided inside the housing 1. The output shaft of the drive mechanism 2 extends into the housing 1 and is connected to the input end of the transmission mechanism. The transmission mechanism is used to reduce speed and increase torque.

[0046] The driving component 3 is rotatably installed inside the housing 1 and is connected to the output shaft of the transmission mechanism. The top surface of the driving component 3 is provided with an actuation conversion part 4.

[0047] At least one massage unit, the massage unit including a transmission component and a massage part 5 disposed at one end of the transmission component, the massage part 5 extending out of the housing 1, and the other end of the transmission component contacting the actuation conversion part 4; the actuation conversion part 4 drives the massage part 5 to move when it rotates with the drive member 3.

[0048] Specifically, such as Figure 1 and Figure 2 As shown, the housing 1 consists of a detachably connected lower housing 1-1 and an upper housing 1-2. The lower housing 1-1 has a mounting slot, and the drive mechanism 2 is installed in the mounting slot. The drive mechanism 2 can be a motor. The lower housing 1-1 has a notch for the output shaft of the drive mechanism 2 to pass through. After the upper housing 1-1 and the upper housing 1-2 are closed, the drive mechanism 2 is fixed. A transmission mechanism is installed inside the housing 1. The transmission mechanism is driven by the output shaft of the drive mechanism 2. The transmission mechanism is used to transmit the driving torque of the drive mechanism 2 and also to amplify the torque through a reduction method to improve the massage intensity. The drive component 3 is rotatably installed inside the housing 1. The drive component 3 is driven by the drive mechanism 2. Optionally, the drive component 3 is a gear. The rotation axis of the drive component 3 is perpendicular to the bottom wall of the lower housing 1-1 and fixed to the lower housing 1-1. An actuation conversion part 4 is provided on the top surface of the drive component 3 at a position offset from the rotation axis. The massage unit is installed inside the housing 1. The massage unit includes a massage head 5 and a transmission assembly connecting the massage head 5 and the actuation conversion unit 4. The massage head 5 extends through the upper housing 1-2 to the outside and provides a direct massage effect. The massage head 5 is a massage head, and its shape can be selected as follows: Figure 3 The rounded structure shown can also be as follows: Figure 4 The structure shows multiple protrusions. Multiple driving elements 3 and massage units can be provided as needed; in this embodiment, four driving elements 3 and massage units are provided, and the four massage units operate synchronously.

[0049] By utilizing the speed reduction and torque amplification effect of the transmission mechanism, the torque output by the drive mechanism 2 is amplified, thereby ensuring that each of the four massage units generates a strong massage force when driving them. The actuation conversion part 4 is set at an eccentric position of the drive member 3. When the actuation conversion part 4 drives the massage unit to move, the actuation conversion part 4 cooperates with the transmission component to enable the massage unit 5 to perform either a circular massage or a vertical massage. Furthermore, the massage unit is driven by the rotation of the drive member 3, ensuring the continuity of the massage unit 5's movement.

[0050] Furthermore, the top surface of the driving member 3 is provided with an eccentric hole 6, which is inclined toward the axis of the driving member 3, and the eccentric hole 6 forms the actuation conversion part 4;

[0051] The transmission assembly includes:

[0052] A transmission rod 7, one end of which is connected to the massage part 5, and the other end is inserted into the eccentric hole 6; the middle part of the transmission rod 7 is provided with a spherical limiting part 8;

[0053] The limiting member 9 is fixed inside the housing 1. The limiting member 9 is provided with a spherical limiting cavity 10 to accommodate the spherical limiting part 8. The limiting member 9 is provided with openings 11 on both sides of the spherical limiting cavity 10 for the transmission rod 7 to pass through.

[0054] Specifically, such as Figure 5 and Figure 6 As shown, in this embodiment, the massage part 5 operates via a circular massage mechanism. In this embodiment, the actuation conversion part 4 is an eccentric hole 6 eccentrically disposed on the top surface of the drive member 3, and the eccentric hole 6 is inclined toward the axial direction of the drive member 3. In this embodiment, the transmission assembly cooperating with the actuation conversion part 4 includes a transmission rod 7 and a limiting member 9. The limiting member 9 is fixed on the upper housing 1-2 and has a spherical limiting cavity 10. The spherical limiting cavity 10 has openings 11 on its upper and lower sides. The transmission rod 7 passes through the spherical limiting cavity 10 through the openings 11. One end of the transmission rod 7 is inserted into the eccentric hole 6, and the other end is connected to the massage part 5. The spherical limiting part 8 between the two ends of the transmission rod 7 is engaged in the spherical limiting cavity 10. The spherical limiting part 8 is rotatable within the spherical limiting cavity 10, and the transmission rod 7 is inclined.

[0055] When the drive member 3 rotates, the eccentric hole 6 moves in a circular motion around the axis of the drive member 3. Due to the cooperation of the spherical limiting part 8 and the spherical limiting cavity 10, both ends of the transmission rod 7 also move in a circular motion around the axis of the drive member 3, thereby causing the massage part 5 to move in a circular motion around the axis of the drive member 3, thus realizing a circular massage mode.

[0056] Furthermore, the transmission mechanism includes:

[0057] The rack 17 is mounted on the output shaft of the drive mechanism 2;

[0058] At least one primary reduction gear 18 is rotatably mounted inside the housing 1. The primary reduction gear 18 includes a primary gear section 19 and a secondary gear section 20 arranged coaxially. The diameter of the primary gear section 19 is larger than the diameter of the secondary gear section 20. The primary gear section 19 meshes with the rack 17.

[0059] At least one secondary reduction gear 21 is rotatably mounted inside the housing 1. The secondary reduction gear 21 includes a third-stage gear section 22 and a fourth-stage gear section 23 arranged coaxially. The diameter of the third-stage gear section 22 is larger than the diameter of the fourth-stage gear section 23. The third-stage gear section 22 meshes with the secondary gear section 20, and the fourth-stage gear section 23 meshes with the driving member 3.

[0060] Specifically, such as Figures 7-9 As shown, the transmission mechanism consists of a rack 17, a primary reduction gear 18, and a secondary reduction gear 21. The number of secondary reduction gears 21 is equal to the number of driving components 3. The rack 17 is sleeved on the output shaft of the driving mechanism 2 to form a worm gear, and the primary reduction gear 18 is formed on the worm wheel that meshes with the rack 17. In this embodiment, there are two primary reduction gears 18, symmetrically distributed on both sides of the rack 17. The rack 17 and the primary reduction gear 18 cooperate to achieve primary speed reduction and torque increase. Each primary reduction gear 18 drives two secondary reduction gears 21, and the primary reduction gear 18 and the secondary reduction gear 21 cooperate to achieve secondary speed reduction and torque increase. Through the two-stage reduction of the transmission mechanism, the reduction ratio reaches more than 60, thereby increasing the torque on each driving component 3 when driven by one driving mechanism 2, and thus increasing the massage force of the massage part 5.

[0061] Furthermore, a bearing 24 is sleeved on the output shaft of the drive mechanism 2, and the outer ring of the bearing 24 is fixed to the inside of the housing 1.

[0062] Specifically, such as Figures 7-9 As shown, a pair of bearings 24 are sleeved on the output shaft of the drive mechanism 2. The pair of bearings 24 are respectively located at both ends of the rack 17, and the outer rings of the bearings 24 are fixed to the lower housing 1-1. By setting the bearings 24, the output shaft of the drive mechanism 2 is supported without affecting its rotation, thus preventing vibration caused by the shaft being suspended during operation from affecting the working stability of the drive mechanism 2, and also improving the service life of the drive structure 2.

[0063] Furthermore, the outer wall of the housing 1 is provided with a plurality of fixing portions 25, and the rotation shafts of the drive member 3, the first-stage reduction gear 18 and the second-stage reduction gear 21 extend from the housing 1 into the fixing portions 25 for fixing.

[0064] Specifically, such as Figure 10 and Figure 11 As shown, multiple fixing parts 25 are formed on the outer bottom wall of the lower housing 1-1. Due to the limited internal space and thin bottom wall of the housing 1, it is impossible to stably fix the rotating shafts of the drive component 3, the first-stage reduction gear 18 and the second-stage reduction gear 21. By setting the fixing parts 25, the rotating shaft extends through the bottom wall of the lower housing 1-1 into the fixing parts 25, thereby making the installation of the rotating shaft more stable.

[0065] Furthermore, reinforcing ribs 26 are connected between adjacent fixing parts 25.

[0066] Specifically, in order to increase the structural strength of the lower shell 1-1, reinforcing ribs 26 are provided between adjacent fixing parts 25 to improve the structural strength.

[0067] Furthermore, the housing 1 is provided with heat dissipation holes 27 at the position corresponding to the drive mechanism 2.

[0068] Specifically, such as Figure 11 As shown, heat dissipation holes 27 are provided on the upper housing 1-2 and the lower housing 1-1 at the positions where the drive mechanism 2 is wrapped, and the heat dissipation holes 27 are used to dissipate heat from the drive mechanism 2.

[0069] Furthermore, the housing 1 is also provided with an oil reservoir 29, which is used to store lubricating grease.

[0070] Specifically, the oil reservoir 29 is provided on the lower housing 1-1 and corresponds to the end of the output shaft of the drive mechanism 2. By providing the oil reservoir 29 and storing grease in the oil reservoir 29, lubrication can be achieved through the grease during gear transmission.

[0071] Example 2

[0072] This embodiment provides another massage mechanism. The same content as in Embodiment 1 will not be repeated here, but the differences are as follows:

[0073] The top surface of the driving member 3 is provided with an annular abutment platform 12 around the axis of the driving member 3. The annular abutment platform 12 is inclined and the top surface of the annular abutment platform 12 forms the actuation conversion part 4.

[0074] The transmission assembly includes:

[0075] A central shaft 13, one end of which is slidably connected to the driving member 3 along the circumferential direction of the driving member 3, and the other end is fixed to the massage part 5;

[0076] Adjusting member 14, which is sleeved on the central shaft 13 and fixed to the central shaft 13, has an abutting part 15 on one side, which abuts against the top surface of the annular abutting platform 12.

[0077] Specifically, such as Figure 12 and Figure 13 As shown, in this embodiment, the massage unit 5 operates in a vertical massage mode. In this embodiment, the actuation conversion unit 4 is an annular abutment platform 12 provided on the top of the drive member 3. The annular abutment platform 12 is coaxially arranged with the drive member 3, and the annular abutment platform 12 is inclined so that the top surface of the annular abutment platform 12 forms a set angle with the top surface of the drive member 3. In this embodiment, the transmission assembly cooperating with the actuation conversion unit 4 includes a central shaft 13 and an adjusting member 14. The central shaft 13 is collinear with the axis of the driving member 3. One end of the central shaft 13 passes through the rotation axis of the driving member 3. The central shaft 13 and the rotation axis of the driving member 3 are slidably connected and cannot rotate relative to each other. The sliding direction of the central shaft 13 and the rotation axis of the driving member 3 is the axial direction of the driving member 3. The adjusting member 14 is sleeved on the central shaft 13 and fixedly connected to the central shaft 13. The bottom of the adjusting member 14 protrudes outward, and the bottom of the protruding part is provided with an abutment part 15. When the central shaft 13 is arranged in a vertical direction, the abutment part 15 abuts against the top surface of the annular abutment platform 12 under the action of gravity, or the abutment part 15 is kept in contact with the top surface of the annular abutment platform 12 under the squeezing action of the massaged body part.

[0078] When the driving member 3 rotates, the annular abutment platform 12 rotates with the driving member 3. Since the top surface of the annular abutment platform 12 has different heights, it abuts against the abutment part 15 during the rotation, causing the height of the abutment part 15 to change constantly. This causes the central axis 13 to drive the massage part 5 to move in a direction perpendicular to the top surface of the driving member 3, thereby realizing a vertical massage mode.

[0079] Furthermore, the transmission assembly also includes:

[0080] The elastic element 16 is sleeved outside the adjusting element 14. One end of the elastic element 16 is fixedly connected to the adjusting element 14, and the other end is fixedly connected to the inside of the housing 1. The elastic element 16 is telescopic along the extension direction of the central axis 13.

[0081] Specifically, such as Figure 12 and Figure 13As shown, a baffle 28 is also formed on the inner side of the upper housing 1-2. The elastic element 16 can be a spring. The elastic element 16 is sleeved on the outside of the adjusting member 14. One end of the elastic element 16 is connected to the protruding part at the bottom of the adjusting member 14, and the other end is connected to the baffle 28. When the abutting part 15 abuts against the top surface of the annular abutting platform 12, causing the height to rise, the elastic element 16 is compressed; when the abutting part 15 abuts against the top surface of the annular abutting platform 12, causing the height to decrease, the elastic element 16 restores its deformation, thereby assisting the adjusting member 14 in resetting.

[0084] Specifically, the supporting massage device is composed of a base and a massage mechanism 30. The massage mechanism 30 can be installed at the foot of the car seat, the leg area of ​​the car seat, or the backrest, for massaging the occupant's feet, legs, or back respectively. Figure 14 As shown, when the massage mechanism 30 is located at the foot of the car seat, a separate support base is required as the base for the massage device; when the massage mechanism 30 is located at the leg position of the car seat, the massage mechanism 30 is directly installed inside the seat leg rest, which serves as the base for the massage device; when the massage mechanism 30 is located at the back of the car seat, the massage mechanism 30 is directly installed inside the seat back, which serves as the base for the massage device; preferably, two massage mechanisms 30 are provided at the foot, leg, and back positions of the car seat.
