[0038] The two foot massage parts 6 are arranged at intervals on the left and right sides, and are respectively a right foot massage part for accommodating the right foot and a left foot massage part for accommodating the left foot. In the first embodiment, the right foot massage part and the left foot massage part are configured to be allowed to swing independently to perform ankle massage. The right foot massage part and the left foot massage part are also configured to be allowed to move telescopically relative to the calf massage device P together to change the distance between the foot massage device 5 and the calf massage device P. Specifically, the right foot massage part and the left foot massage part are respectively mounted on the telescopic bracket 2 in a swingable manner (respectively pivoted to the telescopic bracket 2 in a manner that they can rotate up and down). The telescopic bracket 2 has two sets of pivot ears 2A extending forward and backward, respectively corresponding to the two foot massage parts 6, and the left and right sides of the foot massage part 6 are pivoted to the pivot ears 2A.

[0039] like Fig.10 and Fig.11 The two foot massage parts 6 each include a foot support frame 6A, a roller drive 6B, a first foot massage wheel 6C, a second foot massage wheel 6D, a third foot massage wheel 6E, a first linkage assembly 6F, and a second linkage assembly 6G. The first foot massage wheel 6C, the second foot massage wheel 6D, and the third foot massage wheel 6E are arranged at intervals to massage the soles of the feet. The roller drive 6B is installed on the front side of the foot support frame 6A. The first foot massage wheel 6C is connected to the roller drive 6B to be driven to rotate. In this embodiment, Fig.10 As shown, the roller drive member 6B is a motor, and the first foot massage wheel 6C has a worm gear member meshing with the drive shaft of the motor (the drive shaft and the worm gear member form a worm gear transmission structure). The first foot massage wheel 6C and the second foot massage wheel 6D are connected by a first linkage assembly 6F, and the second foot massage wheel 6D and the third foot massage wheel 6E are connected by a second linkage assembly 6G, so that the multiple foot massage wheels can rotate synchronously. In this embodiment, the first linkage assembly 6F and the second linkage assembly 6G are both pulley transmission assemblies, but it should be understood that they can also be adjusted to gear transmission assemblies.

[0040] The two foot driving mechanisms 8 and the two connecting rods 7 correspond to the two foot massage parts 6 (right foot massage part and left foot massage part) respectively, and are used to control the swing of the two foot massage parts 6. Specifically, the two foot driving mechanisms 8 are arranged at intervals on the left and right sides, and each foot driving mechanism 8 drives the corresponding foot massage part 6 to swing relative to the telescopic bracket 2 through the connecting rod 7. In this embodiment, the connecting rod 7 is arranged between the two pivot ears 2A in the left and right directions, the first end of the connecting rod 7 is pivotally connected to the corresponding foot massage part 6, and the second end is pivotally connected to the foot driving mechanism 8. The foot driving mechanism 8 drives the second end of the connecting rod 7 to move up and down, so that the first end drives the foot massage part 6 to rotate up and down. The connecting rod 7 is arranged between the two pivot ears 2A in the left and right directions, so that the foot massage part 6 can be turned up and lifted more smoothly.

[0041] Combination Figures 6 to 8 In this embodiment, the foot driving mechanism 8 includes a foot driving member 8A, a screw member 8B extending up and down, a nut member 8C sleeved on the screw member 8B, and a position detection member 8D for detecting the up and down movable position of the nut member 8C. The foot driving member 8A is installed on the telescopic bracket 2, and the screw member 8B is rotatably installed on the telescopic bracket 2 and is transmission-connected to the foot driving member 8A to be driven and rotated. In this embodiment, the foot driving member 8A drives the screw member 8B to rotate through the pulley assembly. The nut member 8C is pivotally connected to the second end of the connecting rod member 7, and drives the second end of the connecting rod member 7 to move up and down by rotating the screw member 8B without rotating itself. The position detection member 8D is used to detect the up and down movable position of the nut member 8C. In this embodiment, the position detection member 8D includes a scale member M1 installed on the telescopic bracket 2 and arranged up and down, and a detection member M2 installed on the nut member 8C. The position detection member 8D can be a common photoelectric sensor or other sensor that can detect displacement changes, which will not be repeated.

[0042] The above is the lower limb massager of the first embodiment of the present application. However, the present application may also have other variant designs.

[0043] [Second embodiment] Combination Figure 12 to Figure 14In the second embodiment, the lower limb massager includes two telescopic brackets 2, which correspond to two foot massage parts 6 (right foot massage part and left foot massage part), respectively. The two foot massage parts 6 (right foot massage part and left foot massage part) are respectively swingably mounted on the corresponding telescopic brackets 2. The lower limb massager of the second embodiment includes two telescopic drive mechanisms 3, which are used to drive the two telescopic brackets 2 to telescopically move relative to the calf bracket 1 along the leg length direction, so that the right foot massage part and the left foot massage part can telescopically move independently relative to the calf massage device P. In the first embodiment, the motor of the telescopic drive mechanism 3 extends in the left-right direction, while in the second embodiment, the motor of the telescopic drive mechanism 3 extends in the leg length direction, so that the structure in the left-right direction is more compact. Other features not mentioned in the second embodiment may be the same as those in the first embodiment and will not be repeated.

[0044] In another embodiment, the foot drive mechanism 8 can be replaced by a telescopic push rod. In another embodiment, the telescopic drive mechanism 3 can be replaced by a telescopic spring. When in use, the user's foot applies force to the foot massage part 6, so that the telescopic support 2 moves relative to the calf support 1 in a controlled manner along the leg length direction. In another embodiment, the calf massage part 4 may not be provided on the first support 1.

[0045] The lower limb massager of the present application is installed on the seat of the massage chair. When the foot massage part swings up and down relative to the telescopic bracket, the user's ankle can be stretched and massaged. The ankle stretching massage can promote blood circulation in the foot and improve the massage comfort. The foot massage parts 6 on the left and right sides can swing up and down independently and in a controlled manner, such as synchronously or alternately, which helps to enrich the massage action.

[0046] The present application further provides a massage chair, comprising a seat and a lower limb massager, wherein the lower limb massager is the aforementioned lower limb massager. Specifically, the calf support 1 of the lower limb massager can be directly pivoted to the front side of the seat, and can be controlled to rotate up and down relative to the seat. However, it should be understood that a frame can also be provided to connect to the front side of the seat, and the aforementioned lower limb massager can be installed on the frame.

[0047] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
