DETAILED DESCRIPTION
[0033] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.
[0034] In the claims, specification and the above-mentioned drawings of the present invention, unless otherwise explicitly defined, directional words, such as the use of terms such as "center", "lateral", "longitudinal", "horizontal", "vertical", "top", "bottom", "inside", "outside", "up", "down", "front", "back", "left", "right", "clockwise", "counterclockwise" and the like to indicate directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be understood as limiting the specific protection scope of the present invention.
[0035] The present invention provides a clutch driving structure of a massager, such as Figure 1-7 As shown, the focus here is on Figure 3 and Figure 4 As shown, it includes a motor 1, a first action mechanism 2, a sliding sleeve 3, a rotating shaft 4 and a second action mechanism 5; the first action mechanism 2 can drive the massager to perform a first massage action, and the second action mechanism 5 can drive the massager to perform a second massage action. The first massage action and the second massage action can be a massage action on any existing massager, and are not specifically limited. A specific embodiment is given below;
[0036] The motor 1 has a first output shaft 6 at one end and a second output shaft 7 at the other end. The first output shaft 6 and the second output shaft 7 on the motor 1 are formed at both ends of the rotor of the motor 1 (which is a conventional arrangement in the motor, not shown in the drawings), so that when the rotor rotates, the first output shaft 6 and the second output shaft 7 rotate synchronously; wherein the first output shaft 6 is transmission-connected to the first action mechanism 2, and is further used to drive the massager to perform the first massage action. The transmission connection method is not specifically limited, and can be gear transmission or belt transmission, etc., and the transmission chain can also be provided with a reduction box, a clutch and other structures. The specific structure adopted in this embodiment is given later;
[0037] The sleeve 3 is rotatably sleeved on the shaft 4 and can slide axially along the shaft 4. The shaft 4 is provided with a first clamping portion 8 at one end of the sliding path of the sleeve 3. The end of the sleeve 3 facing the first clamping portion 8 forms a second clamping portion 9. The shapes of the first clamping portion 8 and the second clamping portion 9 are not limited. As long as the shaft 4 and the sleeve 3 are circumferentially clamped and rotate synchronously after the first clamping portion 8 and the second clamping portion 9 are contacted and clamped, the shaft 4 and the sleeve 3 can be circumferentially clamped. In a preferred embodiment, combined with Figure 3 and Figure 4 As shown, a toothed disc 12 is sleeved and fixed on the rotating shaft 4, and a plurality of first teeth 13 are formed on the toothed disc 12 on the side facing the sleeve 3, and the plurality of first teeth 13 are arrayed around the rotating shaft 4 to form the first clamping portion 8. A plurality of second teeth 14 are formed on the end of the sleeve 3 facing the first clamping portion 8, and the plurality of second teeth 14 are arrayed around the rotating shaft 4 to form the second clamping portion 9. When each first tooth 13 is engaged with the gap between each second tooth 14, the rotating shaft 4 and the sleeve 3 are circumferentially clamped and rotate synchronously. In another preferred embodiment, combined with Figure 6 and Figure 7 As shown, a fixing pin 31 is fixed on the rotating shaft 4 and crosses the rotating shaft 4. The end of the fixing pin 31 protrudes from the rotating shaft 4 to form the first clamping portion 8. A clamping groove 32 is provided at one end of the sliding sleeve 3 facing the fixing pin 31. When the end of the fixing pin 31 slides into and is clamped in the clamping groove 32, the rotating shaft 4 and the sliding sleeve 3 are circumferentially clamped and rotate synchronously. The rotating shaft 4 is transmission-connected to the second action mechanism 5, and the rotation of the rotating shaft 4 drives the massager to perform the second massage action.
[0038] The second output shaft 7 is formed with a first helical tooth 10 on its outer periphery, and the sleeve 3 is formed with a second helical tooth 11 on its outer periphery. The first helical tooth 10 is meshed with the second helical tooth 11. The first helical tooth 10 and the second helical tooth 11 described herein do not specifically refer to having only one continuous tooth, but may also be composed of a plurality of teeth arranged side by side (e.g. Figure 3 and Figure 4 As shown in FIG. 1 ), the second output shaft 7 is perpendicular to the rotating shaft 4, and the first helical teeth 10 and the second helical teeth 11 are arranged in a rotational direction so that when the second output shaft 7 rotates forward ( Figure 3In the direction of the middle arrow), the sliding sleeve 3 can be driven to slide toward the first clamping portion 8, so that the first clamping portion 8 is clamped with the second clamping portion 9, and then the rotating shaft 4 can be driven to rotate, so that the massager performs the second massage action. When the second output shaft 7 is reversed ( Figure 4 In the direction of the middle arrow), the sliding sleeve 3 can be driven to slide away from the first clamping portion 8, so that the first clamping portion 8 is separated from the second clamping portion 9, and the second massage action is stopped.
[0039] Preferably, in order to prevent the second output shaft 7 from reversing and causing the sleeve 3 to slide too far in the direction away from the first clamping portion 8, causing the first helical teeth 10 and the second helical teeth 11 to disengage and cause failure, a blocking portion 15 is also formed on the rotating shaft 4 to limit the sleeve 3 from sliding between the blocking portion 15 and the first clamping portion 8. More specifically, in the present embodiment, a small pulley 28 is sleeved and fixed on the rotating shaft 4, and the blocking portion 15 is the side of the small pulley 28 facing the sleeve 3.
[0040] A massager, such as Figure 1-5 As shown, the clutch drive structure of the massager as described above is applied, and a kneading hammer swing arm 16 is provided, and the first action mechanism 2 includes a kneading transmission shaft 17 and an eccentric wheel 18, and the second action mechanism 5 includes a hammering transmission shaft 19, an eccentric shaft 20 and a connecting rod group 21;
[0041] The kneading transmission shaft 17 extends left and right, and the first output shaft 6 is connected to the kneading transmission shaft 17 for driving the kneading transmission shaft 17 to rotate. Preferably, a reduction box 27 is arranged between the first output shaft 6 and the kneading transmission shaft 17; the deflection wheel 18 is fixed on the kneading transmission shaft 17, and an inclined shaft 22 inclined to the kneading transmission shaft 17 is formed on the deflection wheel 18. The middle part of the kneading hammer swing arm 16 is sleeved and pivoted on the inclined shaft 22, and the top of the kneading hammer swing arm 16 extends upward for abutting against the human body for massage. When the first output shaft 6 transmits power to the kneading transmission shaft 17, the kneading transmission shaft 17 rotates, and the top of the kneading hammer swing arm 16 performs a first massage action, which is specifically an action imitating human hand kneading (the realization of this action is a conventional technical means on the shoulder and neck massager, so the action is not described in detail);
[0042] The hammering transmission shaft 19 and the kneading transmission shaft 17 are spaced front and back and parallel to each other. The rotating shaft 4 is connected to the hammering transmission shaft 19 for driving the hammering transmission shaft 19 to rotate when rotating. Preferably, a decelerating belt transmission is provided between the rotating shaft 4 and the hammering transmission shaft 19. More specifically, a large pulley 29 is sleeved and fixed on the hammering transmission shaft 19, and a transmission belt 30 is sleeved between the small pulley 28 and the large pulley 29 for transmission. The eccentric shaft 20 is parallel to the hammering transmission shaft 19 and is fixed to the hammering transmission shaft 19. One end of the connecting rod group 21 is sleeved and pivotally connected to the eccentric shaft 20, and the other end is hinged to the bottom end of the kneading hammer swing arm 16. The specific structure of the connecting rod group 21 can be designed differently according to conventional technical means of those skilled in the art. As long as the hammering transmission shaft 19 can drive the bottom end of the kneading hammer swing arm 16 to swing back and forth when rotating, and then drive the top end of the kneading hammer swing arm 16 to swing back and forth, the aforementioned second massage action can be performed. Specifically in the present embodiment, the connecting rod group 21 includes a connecting rod 23 and a rocker arm 24. One end of the connecting rod 23 is pivotally connected to the eccentric shaft 20, and the other end is pivotally connected to the rocker arm 24, so that the other end of the rocker arm 24 can swing left and right. One end of the rocker arm 24 that swings left and right is hinged to the bottom end of the kneading hammer swing arm 16. More specifically, a ball head 26 is formed at the bottom end of the kneading hammer swing arm 16, and a ball seat 25 is formed on the rocker arm 24. The ball head 26 is movably embedded in the ball seat 25 to hinge the bottom end of the kneading hammer swing arm 16 with the rocker arm 24.
[0043] The above description is only a preferred embodiment of the present invention and is not a limitation on the design of this case. Any equivalent changes made based on the design key of this case shall fall within the protection scope of this case.
