DETAILED DESCRIPTION

[0033] The preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings, and the present application will be further described.

[0034] Firstly, the massage driving module according to an embodiment of the present application will be described in combination with Figs. 1~5 The massage driving module according to an embodiment of the present application is used to drive multiple massage heads to vibrate synchronously, and has a wide application scenario.

[0035] As shown in Figs. 1~5 The massage driving module according to an embodiment of the present application comprises: a mounting seat 1, a driving member 2, a rotating fixed shaft, a massage head 41 mounting rack 4, and an eccentric wheel vibration mechanism 5.

[0036] Specifically, as shown in Figs. 1~5As shown, in this embodiment, the drive component 2 is mounted on the mounting base 1, and the drive component 2 is a drive motor; the input end of the eccentric wheel vibration mechanism 5 is connected to the output end of the drive component 2, and the output end of the eccentric wheel vibration mechanism 5 is hinged to the massage head 41 mounting bracket 4; the massage head 41 mounting bracket 4 is sleeved on the rotating fixed shaft and is rotatably connected to the rotating fixed shaft through the rotating bearing 31, and a pair of massage heads 41 are symmetrically arranged at both ends of the massage head 41 mounting bracket 4 about the rotating fixed shaft; both ends of the rotating fixed shaft are fixed to the outer housing, and the housing limits the vertical movement of the massage heads 41; the drive component 2 drives one end of the massage head 41 mounting bracket 4 to move up and down reciprocally through the eccentric wheel vibration mechanism 5, and the massage head 41 mounting bracket 4 swings around the rotating fixed shaft, driving the other end of the massage head 41 mounting bracket 4 to move up and down reciprocally in the opposite direction. Under the constraint of the outer casing, the eccentric wheel vibration mechanism 5 converts the rotational motion of the drive component 2 into the up-and-down reciprocating motion of the massage head 41 at one end of the massage head 41 mounting bracket 4. Due to the rotation fixed shaft, the massage heads 41 at both ends of the massage head 41 mounting bracket 4 move in a seesaw motion, with the massage head 41 at one end of the massage head 41 mounting bracket 4 moving upward and the massage head 41 at the other end moving downward. Through the eccentric wheel vibration mechanism 5, the massage head 41 mounting bracket 4, and the rotation fixed shaft, one drive component 2 drives two massage heads 41 to vibrate synchronously, realizing synchronous massage of multiple points of the user, improving efficiency, and the overall structure is compact and exquisite.

[0037] Furthermore, such as Figs. 1~5 As shown, in this embodiment, the eccentric wheel vibration mechanism 5 includes an eccentric wheel and a connecting rod 54. The active end of the eccentric wheel is connected to the output end of the drive member 2, and the eccentric end of the eccentric wheel is connected to the bottom end of the connecting rod 54 via a ball bearing 53. The top end of the connecting rod 54 is hinged to the massage head 41 mounting frame 4. The drive member 2 drives the eccentric wheel to rotate, which in turn causes the massage head 41 mounting frame 4 to vibrate via the connecting rod 54. Specifically, the drive member 2 drives the eccentric wheel to rotate, causing one end of the connecting rod 54 connected to the eccentric wheel to move along an elliptical track. Due to the hinge between the connecting rod 54 and the massage head 41 mounting frame 4 and the limitation of the housing, the massage head 41 mounting frame 4 connected to the other end of the connecting rod 54 vibrates up and down.

[0038] Furthermore, such as Figs. 1~5 As shown, in this embodiment, the eccentric wheel includes: a rotating wheel 51 and an eccentric shaft 52; the rotating wheel 51 is coaxially fixed to the output end of the drive component 2; the eccentric shaft 52 is eccentrically fixed to the end face of the rotating shaft, and the axis of the eccentric shaft 52 does not coincide with the axis of the rotating wheel 51. The eccentric shaft 52 is connected to the bottom end of the connecting rod 54 through a ball bearing 53. By adjusting the eccentricity of the eccentric wheel and the speed of the drive motor, the massage needs applicable to different massage areas can be met.

[0039] Furthermore, such as Figs. 1~5As shown, in this embodiment, there are two eccentric wheel vibration mechanisms 5 and two massage head 41 mounting brackets 4. The two eccentric wheel vibration mechanisms 5 are hinged to the two massage head 41 mounting brackets 4 respectively. Both massage head 41 mounting brackets 4 are rotatably connected to a rotating fixed shaft. The drive member 2 drives the two eccentric wheel vibration mechanisms 5 to move synchronously through a transmission mechanism 6. The transmission mechanism 6 distributes the single output end of the drive member 2 into two synchronously rotating output ends. Since different products require different numbers of massage heads 41, by setting the transmission mechanism 6 and adding eccentric wheel vibration mechanisms 5 and massage head 41 mounting brackets 4, the output power of one drive member 2 is synchronously transmitted to four massage heads 41, further increasing the number of synchronously driven massage heads 41 to adapt to different products.

[0040] Furthermore, such as Figs. 1~5 As shown, in this embodiment, the transmission mechanism 6 includes: a transmission shaft 61 and a pair of bevel gears; both ends of the transmission shaft 61 pass through the mounting base 1 and are rotatably connected to the mounting base 1, and both ends of the transmission shaft 61 are respectively connected to two eccentric wheel vibration mechanisms 5; the pair of bevel gears are divided into a first bevel gear 62 and a second bevel gear 63, the first bevel gear 62 is installed on the output end of the drive member 2, and the second bevel gear 63 is installed on the transmission shaft 61, the first bevel gear 62 and the second bevel gear 63 mesh with each other; the drive member 2 drives the first bevel gear 62 to rotate, thereby driving the second bevel gear 63 and the transmission shaft 61 to rotate. By using a pair of bevel gears and the transmission shaft 61, the output power of the drive motor is distributed into two synchronously rotating output powers, and then the massage head 41 mounting bracket 4 and the rotating fixed shaft distribute the two output powers into the synchronous vibration of the four massage heads 41, realizing the user's synchronous massage of multiple points, further improving the user experience, and the overall structure is compact and occupies little space.

[0041] In use, the module is installed in the outer housing. The drive motor drives the first bevel gear 62 to rotate, which in turn drives the second bevel gear 63 and the transmission shaft 61 to rotate, further driving the eccentric wheel to rotate. Through the connecting rod 54, the massage head 41 at one end of the massage head 41 mounting bracket 4 vibrates. Then, through the rotating fixed shaft and the rotating bearing 31, the massage head 41 at the other end of the massage head 41 mounting bracket 4 vibrates in the opposite direction, thus achieving massage of multiple points.

[0042] Above, refer to Figs. 1~5 The present invention describes a massage drive module according to an embodiment of the present invention, which can synchronously distribute the driving force of a drive motor to multiple massage heads, thereby driving the multiple massage heads to vibrate at high frequency; the overall structure is compact and ingenious, and can be installed on different products according to product requirements, with modular design and wide applicability.
