Figure 2 and Figure 3 As shown, the left foot massager P21 and the right foot massager P22 can slide together along the length of the leg relative to the leg massager P1. The left foot massager P21 and the right foot massager P22 can be flipped up and down respectively to stretch and massage the user's left and right ankles, promoting blood circulation in the feet. The lower limb massager of this application can be installed on the front side of the seat of a massage chair and configured to flip up and down relative to the front side of the massage chair seat to massage the user's lower limbs. However, it should be understood that the lower limb massager of this application can also be used as a standalone massager, designed to be installed on a bed, such as a hospital bed, to massage the patient's feet. The specific structures that the lower limb massager can adopt will be described in detail below with reference to the figures.

[0033] Combination Figures 4 to 10 The lower limb massager of this application includes a leg support 1, a foot frame 2 and a sliding drive mechanism 3. The leg massage device P1 is mounted on the leg support 1, and the foot massage device P2 is mounted on the foot frame 2. The foot frame 2 is configured to slide relative to the leg support 1 along the leg length direction. The sliding drive mechanism 3 is disposed between the leg support 1 and the foot frame 2 to drive the foot frame 2 to slide.

[0034] like Figure 7 The leg support 1 has sliding grooves 1A on both the left and right sides, and a pivot lug on the upper side, which is pivotally connected to the seat of the massage chair. The leg massage device P1 is installed on the front side of the leg support 1.

[0035] like Figure 7 The foot support 2 has rollers 2A and sliders 2B on its left and right sides, combined with Figure 7The roller 2A and slider 2B are arranged within the groove 1A, allowing the foot support 2 and leg support 1 to slide in the leg length direction. This enables the foot support 2 to move along the leg length to accommodate users with different leg lengths. In another embodiment, only the roller 2A or only the slider 2B may be provided. The foot massage device P2 is mounted on the foot support 2.

[0036] like Figure 7 The sliding drive mechanism 3 includes a sliding drive motor 3A, a lead screw 3B, and a lead screw nut 3C, combined with... Figure 5 A sliding drive motor 3A is mounted on the foot support 2. A lead screw 3B extends along the leg length and is driven to rotate by the sliding drive motor 3A. A lead screw nut 3C is mounted on the leg support 1 and sleeved on the lead screw 3B. When the lead screw 3B rotates forward or backward, the lead screw nut 3C moves upward or downward relative to the lead screw 3B, causing the foot support 2 to slide relative to the leg support 1. The sliding drive mechanism 3 may further be equipped with a sliding position detection mechanism for detecting the sliding position of the foot support 2 relative to the leg support 1, such as a photoelectric position detection mechanism. The sliding drive mechanism 3 can also be adjusted to be a telescopic push rod.

[0037] Combination Figures 8 to 10 For ease of explanation, the X direction in the diagram represents the front-to-back direction, the Y direction represents the left-to-right direction, and the Z direction represents the bottom-to-up direction. The foot massage device P2 includes a left foot support 4, a right foot support 5, and a flipping drive mechanism 6. The flipping drive mechanism 6 drives the left foot support 4 and right foot support 5 to flip up and down. It includes a motor 6A, a rotating shaft 6B, a first gear 6C, a first arc-shaped gear 6D, a second gear 6E, a reversing gear 6F, and a second arc-shaped gear 6G. The motor 6A is positioned between the left foot support 4 and right foot support 5 along the left-to-right direction and is mounted on the foot frame 2 via a motor support 7.

[0038] The left foot support 4 is configured to rotate vertically relative to the footrest 2 to stretch the user's left ankle. The right foot support 5 is configured to rotate vertically relative to the footrest 2 to stretch the user's right ankle. Specifically, combined with Figure 9 The foot support 2 has a first pivot part M11 extending forward on both the left and right sides. The left foot support 4 and the right foot support 5 have an outer pivot part M12 on their outer sides in the left and right directions. The outer pivot part M12 is pivotally connected to the first pivot part M11. The motor support base 7 has a second pivot part M21 on both the left and right sides. The left foot support 4 and the right foot support 5 have an inner pivot part M22 on their inner sides in the left and right directions. The inner pivot part M22 is pivotally connected to the second pivot part M21 of the motor support base 7. That is, the inner sides of the left foot support 4 and the right foot support 5 are indirectly pivotally connected to the foot support 2 through the motor support base 7. In this way, the left foot support 4 and the right foot support 5 can be flipped up and down relative to the foot support 2 respectively.

[0039] The rotating shaft 6B, first gear 6C, and first arc-shaped toothed joint 6D of the flipping drive mechanism 6 form a left transmission assembly to drive the left foot bracket 4 to flip up and down. The rotating shaft 6B, second gear 6E, reversing gear 6F, and second arc-shaped toothed joint 6G form a right transmission assembly to drive the right foot bracket 5 to flip up and down. The left and right transmission assemblies share the same rotating shaft 6B as the transmission structure. The rotating shaft 6B is arranged left and right and is connected to the motor 6A. The rotating shaft 6B can be connected to the motor 6A through a worm gear structure.

[0040] The left transmission assembly is located between the motor 6A and the left foot bracket 4, and is used to drive the left foot bracket 4 to rotate up and down. Specifically, the first gear 6C is connected to the motor 6A via the rotating shaft 6B, and the first arc-shaped gear 6D is mounted on the left foot bracket 4 and meshes with the first gear 6C.

[0041] The right transmission assembly is located between the motor 6A and the right foot bracket 5, and is used to drive the right foot bracket 5 to rotate up and down. Specifically, the second gear 6E is connected to the motor 6A via the rotating shaft 6B. The second gear 6E and the first gear 6C are corresponding in the left-right direction and are coaxially arranged (both are sleeved on the rotating shaft 6B and rotate with it). The second arc-shaped tooth condition 6G is installed on the right foot bracket 5. The reversing gear 6F meshes with the second gear 6E and the second arc-shaped tooth condition 6G respectively, so that the rotation direction of the second arc-shaped tooth condition 6G is opposite to the rotation direction of the first arc-shaped tooth condition 6D. Because the second gear 6E corresponds to the first gear 6C and is coaxially arranged, by setting the reversing gear 6F, the rotation direction of the second arc-shaped tooth condition 6G is opposite to that of the first arc-shaped tooth condition 6D, that is, when one rotates forward, the other rotates in reverse. In this way, the left foot bracket 4 and the right foot bracket 5 can rotate up and down alternately, stretching the user's ankle alternately.

[0042] In this embodiment, a detection mechanism 8 for detecting the rotation speed of the rotating shaft 6B is provided between the rotating shaft 6B and the foot frame 2. The rotation speed of the rotating shaft 6B is detected by the detection mechanism 8. The control mechanism of the lower limb massager (not shown in the figure) can determine the upper and lower rotation positions of the left foot support 4 and the right foot support 5 by combining the number of rotations of the rotating shaft 6B.

[0043] Combination Figure 1 The left foot support 4 and the right foot support 5 can also be equipped with massage airbags (not shown in the figure) to massage the user's instep and fix the foot. The massage airbags are installed on the upper shell covering the left foot support 4 and the right foot support 5.

[0044] The above is one embodiment of the lower limb massager of this application. It should be understood that this application may have other modified designs. In another embodiment, the motor 6A may be a dual-output shaft motor, driving the first gear 6C and the second gear 6E to rotate through the output shafts on both sides respectively. In another embodiment, the first gear 6C and the second gear 6E may also be arranged on different axes. In another embodiment, the first gear 6C and the second gear 6E may not be directly sleeved on the rotating shaft 6B, but transmission gear sets may be respectively arranged between the first gear 6C and the rotating shaft 6B, and between the second gear 6E and the rotating shaft 6B for transmission. In another embodiment, the sliding drive mechanism 3 may be replaced with a telescopic spring. In another embodiment, the leg support 1 and the sliding drive mechanism 3 may not be provided, that is, the foot frame 2 may be directly pivotally connected to the front side of the seat of the massage chair.

[0045] This application also provides a massage chair, including a seat and a lower limb massager installed on the front side of the seat, wherein the lower limb massager is the aforementioned lower limb massager.

[0046] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
