Description
Technical Field
[0001] The utility model relates to the technical field of massage chairs, in particular to a transmission mechanism for a massage core to realize different massage techniques. Background Art
[0002] The existing single-movement or dual-movement massage chairs on the market, if set up with two sets of massage arms, the massage arms are generally set up on each side of the left and right. The massage arms thereon can mainly perform synchronous or asynchronous kneading massage, and cannot achieve a variety of massage techniques through the forward and reverse rotation of the motor. Summary of the invention
[0003] The technical problem to be solved by the utility model is to provide a transmission mechanism capable of realizing synchronous or asynchronous kneading and massaging switching of multiple massage arms by driving a motor to rotate forward and reversely in order to address the deficiencies of the prior art.
[0004] In order to achieve the above-mentioned purpose, the following technical scheme is adopted: a transmission mechanism for a massage movement to realize different massage techniques, comprising a base plate, a driving motor and a kneading assembly are arranged on the base plate, wherein the driving motor drives the kneading assembly, the kneading assembly comprises a first kneading assembly and a second kneading assembly, the first kneading assembly comprises a first kneading shaft, a first oblique seat is arranged on the first kneading shaft, a first kneading arm is arranged on the first oblique seat cover, the second kneading assembly comprises a second kneading shaft, a second oblique seat is arranged on the second kneading shaft, a second kneading arm is arranged on the second oblique seat cover, the first kneading shaft and the second kneading shaft are parallel to each other The gear set is connected through transmission, and the gear set includes a driving gear arranged on the first kneading shaft and a passive gear rotatably arranged on the second kneading shaft. The driving motor drives the driving gear, and the driving gear is meshed with the passive gear. A forward and reverse reversing mechanism is provided between the passive gear and the second kneading shaft. The forward and reverse reversing mechanism includes an inner sleeve fixed on the second kneading shaft, and the passive gear can rotate relative to the inner sleeve. A limiting groove is provided in the passive gear, and a limiting protrusion is provided on the side wall of the inner sleeve. When the passive gear rotates forward and reversely, the limiting groove respectively contacts with the two side surfaces of the limiting protrusion to realize the switching of the kneading direction of the second kneading arm.
[0005] By adopting the above technical solution, the driving motor drives the first kneading shaft to drive the active gear to rotate forward, and the first kneading shaft drives the passive gear to rotate through the active gear, and one side surface of the limiting protrusion of the inner sleeve conflicts with the limiting groove and is therefore driven to rotate forward at the same time. The first kneading arm and the second kneading arm can massage in the same direction when the motor is not switched to forward and reverse rotation, that is, the first kneading arm and the second kneading arm perform the pinching action synchronously, and after the motor switches to reverse rotation, the passive gear also reverses accordingly, while the inner sleeve does not move, and when the limiting groove of the passive gear conflicts with the other side surface of the limiting protrusion, there is a phase difference between the first kneading shaft and the second kneading shaft, and when the first kneading arm on the first kneading shaft performs the "pinching" action, the second kneading arm on the second kneading shaft switches to The kneading and releasing action of the first kneading arm and the second kneading arm is opposite at this time; if you want to make the massage kneading and releasing action directions of the first kneading arm and the second kneading arm the same again, you only need to rotate the motor forward again to make the driven gear rotate and change the conflicting position with the inner sleeve. The delay when the limit groove conflicts with the limit protrusion when the driven gear rotates can be used to re-knead and release massage in the same direction. The kneading and releasing directions of the first kneading arm and the second kneading arm can be controlled by the forward and reverse reversing mechanism. A through groove can be provided in the limit groove to allow the second kneading shaft to pass through so as not to affect the rotation of the second kneading shaft. When the driven gear rotates forward or reverse, different sides of the limit protrusion will conflict with the limit groove. The structure is simple and reasonable. The limit groove can also be provided on the inner sleeve, and the limit protrusion can also be provided on the driven gear. The two can be interchanged according to selection.
[0006] A transmission mechanism for a massage movement to achieve different massage techniques can be further configured as follows: a first limiting surface and a second limiting surface are provided on the side wall of the limiting groove; when the first kneading shaft rotates forward, the first limiting surface is in contact with one side surface of the limiting protrusion, so that the second kneading arm on the second kneading shaft and the first kneading arm knead in the same direction; when the first kneading shaft is reversed, the second limiting surface rotates 180° along the axis of the second kneading shaft and is in contact with the other side surface of the limiting protrusion, so that the second kneading arm on the second kneading shaft and the first kneading arm are kneaded in the opposite direction.
[0007] By adopting the above technical solution, when the first limiting surface or the second limiting surface respectively contacts the limiting protrusion, the second kneading shaft can be driven to rotate in the same direction or in the opposite direction. When switching between forward and reverse kneading, the passive gear has a phase difference of 180° from contacting the first limiting surface to contacting the second limiting surface after rotation. Therefore, switching between same-direction kneading or reverse kneading can be achieved, thereby making the massage method more diverse. At the same time, the rotation angle of the passive gear in the present application can have some deviation, and it is not necessary to rotate 180° to achieve the technical solution of the present application.
[0008] A transmission mechanism for a massage movement to achieve different massage techniques can be further configured as follows: the first kneading arm and the second kneading arm are both configured as two, and the spacing between the first kneading arms on the first kneading shaft is greater than the spacing between the second kneading arms on the second kneading shaft.
[0009] By adopting the above technical solution, since the spacing between the first kneading arms on the first kneading shaft is greater than the spacing between the second kneading arms on the second kneading shaft, and the number of the first kneading arms and the second kneading arms is set to 2, two massage techniques can be formed: A. The first kneading arm and the second kneading arm on the left side, and the first kneading arm and the second kneading arm on the right side form a set of kneading separately; B. The first kneading arm and the second kneading arm on the left side, and the first kneading arm and the second kneading arm on the right side simultaneously form a large kneading group, thereby increasing the massage techniques.
[0010] A transmission mechanism for a massage movement to achieve different massage techniques can be further configured such that the first limit surface and the second limit surface are located on the same horizontal plane.
[0011] With the above technical solution, the first limiting surface and the second limiting surface are located on the same horizontal plane, so that when the driven gear rotates, the first limiting surface or the second limiting surface of the limiting groove contacts the side surface of the limiting protrusion with a phase difference of exactly 180°.

The driving motor 2 drives the first kneading shaft 31 to drive the driving gear 51 to rotate, and then the first kneading shaft 31 drives the passive gear 52 to rotate through the driving gear 51. A forward and reverse reversing mechanism 6 is provided between the passive gear 52 and the second kneading shaft 41. 6 comprises an inner sleeve 61 fixed on the second kneading shaft 41, the driven gear 52 can rotate relative to the inner sleeve 61, so that the first kneading arm 33 and the second kneading arm 43 can knead and massage in the same direction or in the opposite direction, the side wall of the inner sleeve 61 is provided with a limiting protrusion 611, the driven gear 52 is provided with a through slot for the second kneading shaft 41 to pass through and a limiting slot 512 arranged outside the through slot, and the side wall of the limiting slot 512 is provided with a first limiting surface 513 and a second limiting surface 514 located on the same horizontal plane, as shown in FIG. Figure 7 As shown, when the first kneading shaft 31 is reversed, the second limiting surface 514 rotates 180° along the axis of the second kneading shaft 41 and contacts the other side of the limiting protrusion 611, so that the second kneading arm 43 on the second kneading shaft 41 and the first kneading arm 33 are kneaded asynchronously. Since the passive gear 52 can rotate within the range of 0-180° relative to the inner sleeve 61, the active gear 51 can achieve a phase difference of 180° when driving the passive gear 52 to rotate.
