[0053] To have a further understanding and recognition of the purpose, features and effects of the present invention, the following is described in detail with reference to the drawings:

[0054] First, please refer to Figure 1 、 2As shown in FIGS. 3 and 4, a lifting structure for leg lifting and massaging includes: a base 10, a swing arm 20, a support link 30, and two massage units 40. The base 10 forms a pivot portion 12 with two vertical plates 11. At least one reinforcing plate body 13 is connected to the two vertical plates 11, so that the pivot portion 12 has a space for the swing arm 20 to swing back and forth. A pivot hole 111 is provided at an eccentric position of the two vertical plates 11, and a connection hole 112 is provided at a position above the pivot hole 111 of the two vertical plates 11. Both ends of the swing arm 20 respectively form a fulcrum end 21 and a swing end 22. A first driving motor 23 is provided inside the fulcrum end 21. The fulcrum end 21 is assembled into the pivot portion 12, and the axis 231 of the output end of the first driving motor 23 is connected to the pivot holes 111 of the two vertical plates, so as to drive the swing arm 20 to swing back and forth in the pivot portion 12 by the first driving motor 23. A second driving motor 24 is provided inside the swing end 22, and the axis 241 of the output end of the second driving motor 24 passes through both sides of the swing end 22. One end of the support link 30 is pivotally provided at the connection hole 112 of the two vertical plates through a first shaft 31, and the other end of the support link 30 is higher than the swing end 22 of the swing arm 20 and penetrates through a second shaft 32. Both of the two massage units 40 have a driving end 41 and a passive end 42. The driving ends 41 of the two massage units 40 are installed on both sides of the swing end 22 to be connected and actuated with the axis 241 of the second driving motor 24, and the passive ends 42 of the two massage units 40 are connected to the second shaft 32 of the support link 30 through penetration, so that the two massage units 40 and the swing arm 20 and the base 10 form a Z shape, and the passive end 42 is higher than the driving end 41 through the support link 30.

[0055] Both of the two massage units 40 are provided with a first massage roller 43 and a second massage roller 44 that are interlocked. The two first massage rollers 43 are located at the driving ends 41 of the two massage units 40 and are driven by being connected to the axis 241 of the second driving motor 24. The two second massage rollers 44 are located at the passive ends 42 of the two massage units 40 and are connected to the second shaft 32 through penetration.

[0056] For an embodiment of the structural interlock of the massage unit 40, please refer to Figure 3 、 4 As shown in FIGS., the first massage rollers 43 and the second massage rollers 44 between the two massage units 40 are all driven and interlocked by a belt 45.

[0057] For another embodiment of the structural interlock of the massage unit 40, please continue to refer to Figure 5As can be seen, the first massage rollers 43 and the second massage rollers 44 of the two massage units 40 are both provided with a ring gear portion 431, 441, and a chain 46 is used to traction and link the ring gear portions 431, 441 of the first and second massage rollers 43, 44 of the two massage units 40.

[0058] For another embodiment of the structural linkage of the massage unit 40, please refer to Figure 6 As can be seen, the first massage rollers 43 and the second massage rollers 44 of the two massage units 40 are both provided with a ring gear portion 431, 441, and a gear 47 is provided between the first and second massage rollers 43, 44 of the two massage units 40 to mesh and link with the ring gear portions 431, 441 of the first and second massage rollers 43, 44 of the two massage units 40.

[0059] For the actual use state of its structure, please continue to refer to Figure 3 、 7 As shown in 8, 9, and 10, the massage mechanism provides the user with massage of the legs in a sitting position. The passive ends 42 of the two massage units 40 are facing the user. The user lifts the feet and naturally places them on the two massage units 40. The massage ranges of the two massage units 40 include the thighs and calves. Thus, when the first and second drive motors 23, 24 of the massage mechanism are controlled and enabled, the first drive motor 23 drives the swing arm 20 to swing back and forth, and drives the two massage units 40 to roll and massage through the second drive motor 24. Furthermore, the two massage units 40 are linked by the swing arm 20 to displace and massage along the user's thighs, inner knees, and calves. Since the top of the pivot joint portion 12 is further connected to the passive ends 42 of the two massage units 40 through the support link 30, the swing arm 20 will abut against the support link 30 during the upward swing process, thereby restricting the upward swing angle of the swing arm 20 within 70 degrees, so that the swing end 22 of the swing arm 20 can only swing back and forth between the calf positions for massage. The passive ends 42 of the two massage units 40 are simultaneously supported by the support link 30 and kept higher than the driving end 41. Therefore, when the swing end 22 of the swing arm 20 swings upward to the highest point, the passive ends 42 of the two massage units 40 can indeed massage upward along the thighs. On the contrary, when the swing arm 20 swings downward, the passive end 42 gradually massages downward from the thighs to the calves, and the driving end 41 is driven downward by the swing end 22 to massage from the calves to the ankles and heels, thus achieving the massage effect of the thighs and calves comprehensively.

[0060] Furthermore, a cloth cover 50 can be sleeved outside the two massage units 40, as Figure 11 shown.

[0061] With the structure of the above specific embodiments, the following benefits can be obtained: A support link 30 is connected between the passive ends 42 of two such massage units 40 and the top of the pivot portion 12. One end of the support link 30 can abut and limit the upward swing angle of the swing arm 20, while the other end of the support link 30 supports the passive ends 42 of two such massage units 40. When the swing arm 20 drives two such massage units 40 to swing back and forth for massage, the state where the passive end 42 is higher than the driving end 41 can be maintained, preventing the passive ends 42 of two such massage units 40 from forming a drooping state, so that the passive end 42 can truly support the thigh and massage upward, achieving the purpose of massaging the thigh and calf, and greatly improving the massage effect of the massage mechanism.

[0062] The above is only a preferred embodiment of the present invention, and the scope of implementation of the present invention cannot be limited thereby; that is, all equivalent changes and modifications made according to the scope of the patent application of the present invention should still fall within the scope covered by the patent of the present invention.
