[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0046] Example 1

[0047] like Figures 1-18 As shown, a reciprocating massage mechanism includes: a housing, a power unit, and at least one set of massage mechanisms; the massage mechanisms include a transmission assembly, a first swing arm 700, several massage modules 710, and a swing mechanism. The power unit and transmission assembly are both installed within the housing. Of course, in other embodiments, there are also designs where the power unit and transmission assembly are not entirely installed within the housing. The transmission assembly includes one or more transmission stages, and the power unit is connected to the transmission assembly. The massage modules 710 are mounted on the first swing arm 700. The swing mechanism includes a one-way bearing 330, a third shaft 310, a second eccentric shaft 320, a second swing arm 200, and a swing rod 210. The outer ring of the one-way bearing 330 is coaxially connected to the last stage transmission component and rotates with it. The third shaft 310 is coaxially mounted on the inner ring of the one-way bearing 330 and can only rotate relative to the bearing in one circumferential direction. A base support 311 is provided at the bottom of the third shaft 310, and the second eccentric shaft 320 is installed on the edge of the base support 311. The second eccentric shaft 320 does not necessarily have to be at the edge; it only needs to be eccentric and not coaxial with the base support 311. One end of the second swing arm 200 has a second groove 201 along its length. The second eccentric shaft 320 is located in the second groove 201 and slides along it. The other end of the second swing arm 200 is fixedly connected to a swing rod 210. The swing rod 210 is connected to the first swing arm 700 and drives the first swing arm 700 to swing.

[0048] The power device drives the transmission assembly to rotate. When the last-stage transmission member rotates in the first rotation direction, the one-way bearing 330 is driven to rotate in the first rotation direction, thereby driving the third shaft 310 to rotate, and the third shaft 310 drives the second eccentric shaft 320 to perform circular motion, thereby driving the second swing arm 200 to swing. When the last-stage transmission member rotates in the opposite direction of the first rotation direction, the outer ring of the one-way bearing 330 is driven to rotate, and the inner ring of the one-way bearing 330 cannot rotate, thereby failing to drive the third shaft 310 to rotate, and failing to drive the second swing arm 200 to swing.

[0049] In the embodiment, the last-stage transmission member includes the third gear 300, the third gear 300 is installed on the one-way bearing 330, the top end of the third shaft 310 is rotatably installed on the housing through a bearing, of course, the third shaft 310 can also be installed by using a bolt, as long as the third shaft 310 can rotate, and is not easy to loosen and fall off from the housing. The bottom support 311 at the bottom end of the third shaft 310 is arranged below the third gear 300 to support the third gear 300. The bottom support 311 is in a disc shape, the second eccentric shaft 320 is non-coaxially installed with the bottom support 311, and the bottom support 311 drives the second eccentric shaft 320 to perform circular motion.

[0050] In the embodiment, when the third gear 300 rotates clockwise, the inner and outer rings of the one-way bearing 330 are driven to rotate clockwise, thereby driving the third shaft 310 to rotate, and the second eccentric shaft 320 installed on the bottom support 311 drives the swing rod 210 to swing.

[0051] When the third gear 300 rotates counterclockwise, the outer ring of the one-way bearing 330 is driven to rotate counterclockwise, and the inner ring does not rotate, thereby failing to drive the third shaft 310 to rotate, and being in an idle state, so that the swing rod 210 does not swing. The above-mentioned "clockwise" and "counterclockwise" are relative description statements, and the actual case can also be set in reverse.

[0052] By adding the one-way bearing, when the driving motor 800 rotates forward and reverses, the first swing arm 700 has different motion trajectories, so that the motion trajectory of the first swing arm 700 is more abundant, and the massage effect and massage experience are improved.

[0053] In the above-mentioned embodiment, the coaxial arrangement of the one-way bearing 330, the third gear 300 and the third shaft 310 can improve the stability of the mechanism during operation. The outer ring profile of the one-way bearing 330 is non-circular, so that the one-way bearing 330 and the third gear 300 are fixed in the circumferential direction, and the two will not slip.
