[0024] Combined with Figures 1 to 6 , the lower limb massager of the present application includes a leg massage device, a foot massage device 3 and a sliding drive mechanism 4. The leg massage device includes a fixing frame 1 and a calf massage mechanism 2. The sliding drive mechanism 4 is used to drive the entire foot massage device 3 to slide relative to the leg massage device in the leg length direction. The following will be further described in detail.

[0025] The leg massage device is used to massage the calf of the user. A pivot ear is provided on the upper side of the fixing frame 1 of the leg massage device. The fixing frame 1 can be pivotally connected to the seat of the massage chair through the pivot ear, so that the fixing frame 1 can rotate up and down relative to the seat of the massage chair. The massage chair can be provided with a drive mechanism for driving the fixing frame 1 to rotate. The calf massage mechanism 2 is installed on the fixing frame 1 and is used to massage the calf. In this embodiment, the calf massage mechanism 2 includes a calf massage roller 2A that can perform rolling massage on the calf.

[0026] The foot massage device 3 is used to massage the foot of the user and includes a first frame body 5, a second frame body 6, a rotation drive mechanism 7, a foot massage mechanism 8 and a rotation position detection device 9.

[0027] Among them, the first frame body 5 is slidably engaged with the fixed frame 1 in the leg length direction. Specifically, in this embodiment, the fixed frame 1 has chutes 1A located on the left and right sides, and the first frame body 5 has sliding members located on the left and right sides. The chutes 1A and the sliding members are slidably engaged. In this embodiment, the sliding members include sliders 5A and pulleys 5B, but it can also be adjusted to have only one of them. A sliding drive mechanism 4 as described above is provided between the first frame body 5 and the fixed frame 1 to drive the first frame body 5 to slide relative to the fixed frame 1. The sliding drive mechanism 4 includes a second lead screw 4A, a second nut member 4B sleeved on the second lead screw 4A, and a second motor 4C for driving the second lead screw 4A to rotate. In this embodiment, the second nut member 4B is installed on the fixed frame 1, and the second motor 4C is installed on the first frame body 5. The positions of the second nut member 4B and the second motor 4C can be swapped.

[0028] Among them, the second frame body 6 is used to support the user's feet. Combining Figure 4 , the lower side of the first frame body 5 has a pivot rod extending forward, and the rear side of the second frame body 6 has a pivot rod extending upward. Through the aforementioned pivot rods, the second frame body 6 is configured to be able to rotate up and down relative to the first frame body 5. The rotation drive mechanism 7 is located between the first frame body 5 and the second frame body 6, and it stretches the user's ankle by driving the second frame body 6 to rotate up and down relative to the first frame body 5.

[0029] Among them, the rotation drive mechanism 7 includes a first lead screw 7A, a first nut member 7B sleeved on the first lead screw 7A, and a first motor 7C for driving the first lead screw 7A to rotate. In this embodiment, the first nut member 7B is rotatably engaged with the first frame body 5, and the first motor 7C is rotatably engaged with the second frame body 6. Thus, by the rotation of the first lead screw 7A and the movement of the first nut member 7B relative to the first lead screw 7A, the second frame body 6 can rotate up and down relative to the first frame body 5. In another embodiment, it can be configured such that the first motor 7C is rotatably engaged with the first frame body 5, and the first nut member 7B is rotatably engaged with the second frame body 6.

The foot massage mechanism 8 can adopt existing massage structures such as patent applications CN202321791983.6 and CN202321791979.X, which will not be elaborated here. Combining Figure 1 , a massage airbag that squeezes the user's instep when inflated to hold the user's feet on the second frame body can be installed on the second frame body 6. The massage airbag is arranged on the housing of the foot massage device, on the left and right sides of the sole scraping massage part and the rolling massage part of the foot massage mechanism 8. The massage airbag holds the user's feet, which helps to improve the stretching effect of the ankle.

[0031] Among them, the rotation position detection device 9 is installed between the first frame body 5 and the second frame body 6 and is used to detect the rotation position of the second frame body 6 relative to the first frame body 5. In this embodiment, the rotation position detection device 9 includes a scale member 9A and a detection member 9B. The detection member 9B is arranged on the first frame body 5, and the scale member 9A is arranged on the second frame body 6. The positions of the scale member 9A and the detection member 9B can also be swapped. The rotation position detection device 9 in this embodiment is a common rotary position detection structure, and the controller of the lower limb massager can judge the position of the second frame body 6 relative to the first frame body 5 according to the detection signal of the detection member 9B.

[0032] The above is the specific description of the lower limb massager according to an embodiment of the present application. It should be understood that the specific application mode of the present application is not limited to the foregoing specific embodiments. In another embodiment, the first frame body 5 can be set to not be able to move up and down relative to the fixed frame 5. In another embodiment, the first frame body 5 can be pivotally connected to the front side of the seat of the massage chair, and the lower leg massage mechanism 2 is directly installed on the first frame body 5.

[0033] The present application further provides a massage chair, which includes a seat and a lower limb massager installed on the front side of the seat frame, and the lower limb massager is the aforementioned lower limb massager.

[0034] The above is only the specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
