The foot massage device P2 is mounted on the movable frame 2.

[0038] The sliding drive mechanism 3 includes a sliding drive motor 3A, a lead screw 3B, and a nut 3C, combined with... Figure 9A sliding drive motor 3A is mounted on the movable frame 2. A lead screw 3B extends along the leg length and is driven to rotate by the sliding drive motor 3A. A 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 nut 3C moves upward or downward relative to the lead screw 3B, causing the movable frame 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 movable frame 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.

[0039] Combination Figures 10 to 12 The foot massage device P2 includes a left foot support frame 4, a right foot support frame 5, a flipping drive mechanism 6, and a foot massage mechanism 7. For ease of explanation, it is referred to as... Figure 10 The X direction is from right to left, the Y direction is from front to back, and the Z direction is from bottom to top. The flipping drive mechanism 6 drives the left foot support frame 4 and the right foot support frame 5 to flip up and down, stretching and supporting the user's left and right ankles on the left and right foot support frames 4 and 5, respectively. The flipping drive mechanism 6 includes a motor 6A, a rotating shaft 6B connected to the motor 6A, a left linkage component 6C, and a right linkage component 6D. The motor 6A is positioned between the left foot support frame 4 and the right foot support frame 5 in the left-right direction and is mounted on the movable frame 2 via a motor support base 2C.

[0040] The left foot support 4 is configured to tilt vertically relative to the movable frame 2 to stretch the user's left ankle supported thereon. The right foot support 5 is configured to tilt vertically relative to the movable frame 2 to stretch the user's right ankle supported thereon. Specifically, in combination with Figure 10 The movable frame 2 has forward-extending first pivot portions M11 on both its left and right sides. The left foot support frame 4 and the right foot support frame 5 both have outer pivot portions M12 on their outer sides along the left-right direction, with the first pivot portions M11 and the outer pivot portions M12 corresponding to each other. The motor support base 2C has second pivot portions M21 on both its left and right sides. The left foot support frame 4 and the right foot support frame 5 both have inner pivot portions M22 on their inner sides along the left-right direction, with the second pivot portions M21 and the inner pivot portions M22 corresponding to each other. A rotating shaft 6B is positioned on both sides, passing through the first pivot portion M11, the outer pivot portion M12, the second pivot portion M21, and the inner pivot portion M22. In this manner, the left foot support frame 4 and the right foot support frame 5 are configured to rotate up and down around the rotating shaft 6B as the rotation center, thus stretching and supporting the user's ankle. The rotating shaft 6B can be connected to the motor 6A via a worm gear structure.

[0041] The left side of the pivot 6B is connected to the left foot support frame 4 via the left linkage assembly 6C, and the right side is connected to the right foot support frame 5 via the right linkage assembly 6D. Through the linkage assembly located between the pivot 6B and the foot support frame, the rotational force of the pivot 6B can be converted into a rotational driving force that causes the foot support frame to rotate up and down around the pivot 6B. Specifically, combined with... Figure 10 In this embodiment, both the left linkage assembly 6C and the right linkage assembly 6D include an eccentric wheel K1, a swing sleeve K2, a swing connecting rod K3, and an auxiliary connecting rod K4. The eccentric wheel K1 is sleeved on the rotating shaft 6B and rotates with it. The swing sleeve K2 is sleeved on the eccentric wheel K1. The first end of the swing connecting rod K3 is pivotally connected to the swing sleeve K2, and the second end is pivotally connected to the foot support frame. The first end of the auxiliary connecting rod K4 is pivotally connected to the swing sleeve K2, and the second end is pivotally connected to the movable frame 2. Figure 10 The rotation axis of the first end of the auxiliary link K4 and the rotation axis of the first end of the yaw link K3 coincide. The first end of the yaw link K3 is not directly pivotally connected to the yaw sleeve K2; instead, the first end of the auxiliary link K4 is held between it and the yaw sleeve K2. Figure 10 In this embodiment, the eccentric wheels K1 of the linkage components on both sides of the rotating shaft 6B are mounted on the rotating shaft 6B in opposite positions. This assembly method allows the left foot support frame 4 and the right foot support frame 5 to swing up and down alternately when the rotating shaft 6B rotates, thus alternately stretching the user's ankle.

[0042] Foot massage mechanisms 7 are installed on the left foot support frame 4 and the right foot support frame 5, combined with Figure 13 and Figure 14 The foot massage mechanism 7 includes a first foot massage roller 7A, a second foot massage roller 7B, a foot scraping component 7C, and a limiting seat 7D. The first foot massage roller 7A and the second foot massage roller 7B are sleeved on a rotating shaft 6B and rotate accordingly. The first foot massage roller 7A and the second foot massage roller 7B are engaged along the axial direction of the rotating shaft 6B. The foot scraping component 7C includes a sleeve portion T1 and a scraping portion T2. ​​The sleeve portion T1 is clamped between the first foot massage roller 7A and the second foot massage roller 7B. The first foot massage roller 7A has an eccentric engagement portion Q. The sleeve portion T1 is sleeved on the eccentric engagement portion Q. The scraping portion T2 is slidably engaged with the limiting seat 7D (the scraping portion T2 is provided with a sliding pin, and the limiting seat 7D is provided with a sliding groove, and the two are slidably engaged). When the rotating shaft 6B rotates, the eccentric joint Q drives the sleeve T1 to move back and forth. When the sleeve T1 moves back and forth, it drives the scraping part T2 to slide back and forth relative to the limiting seat 7D, thereby realizing foot scraping massage.

[0043] A detection mechanism (not shown in the figure, but may be a rotary photoelectric detection mechanism) for detecting the rotation speed of the rotating shaft 6B can also be set between the rotating shaft 6B and the movable frame 2. The control mechanism of the lower limb massager (not shown in the figure) can determine the up and down swing positions of the left foot support frame 4 and the right foot support frame 5 by combining the number of rotations of the rotating shaft 6B.

[0044] Combination Figure 1 The left foot support frame 4 and the right foot support frame 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 frame 4 and the right foot support frame 5.

[0045] 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, only one foot support frame may be provided. In another embodiment, the eccentric wheels K1 of the linkage components on both sides of the rotating shaft 6B may be in the same mounting position on the rotating shaft 6B. In another embodiment, the linkage components may be adjusted to other transmission structures, such as gear or arc rack transmission structures, with the gear sleeved on the rotating shaft 6B and rotating accordingly, while the arc rack is mounted on the foot support frame. In another embodiment, the sliding drive mechanism 3 may be replaced with a telescopic spring, that is, the position of the movable frame may be adjusted by the user's foot applying force.

[0046] 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.
