[0034] Specifically, rollers 61 are provided on both sides of each slide 4 , and a plurality of rollers may be arranged on one side; the back frame 11 is provided with two guide rods 111 on the rollers 61 on both sides of a corresponding slide 4 .

[0035] It also includes a controller, which is electrically connected to the motor. The controller is used to control each foot frame separately through the telescopic drive mechanism to make the foot frame telescope closer to or away from the upper calf frame 2.

[0036] The separated calf frame structure, by placing a pair of calves on the upper calf frame 2; placing the left foot and the right foot separately in the two foot frames 3, can make the two feet move independently to remove the restrictions of foot massage, and can also make the two feet move synchronously to adapt to different scene requirements. When the two feet's telescopic movements are used in combination, the space walk scene can be realized; and an upper calf frame 2 and two foot frames 3 are set together on the base frame 1, and can be raised or lowered with the rotation of the base frame 1. In addition, the two foot frames 3 independently control the telescopic length, which can solve the problem that users with different leg lengths cannot get the shorter leg or the massage experience is poor during the massage process, and expand the user group of the massage chair.

[0037] When the foot frame 3 slides and retracts, the motor 53 works and drives the screw rod 51 to rotate through the pulley group a, and the screw rod nut 52 can move linearly along the screw rod 51. Since the screw rod nut 52 is installed on the base frame 1, the screw rod nut 52 is fixedly connected to the base frame 1, so that the screw rod 51 slides up and down relative to the screw rod nut 52, which can drive the slide 4 to move synchronously. When the slide 4 slides relative to the base frame 1, the roller 61 moves in the guide groove 62 to ensure that the slide 4 does not deviate during the telescopic sliding process. The slide 4 drives the foot frame 3 to complete the up and down sliding and telescopic operation, and the telescopic operation is convenient.

[0038] The base frame 1 is also covered by the back plate 1a, and the exposed wheel groove 1a1 on the back plate 1a also contacts the supporting wheel. When swinging, the back plate 1a is lifted by the supporting wheel, so that the base frame 1 drives the upper calf frame 2 and two foot frames 3 thereon to rotate and lift together; and the two back covers 1b can be used to cover the slide 4 respectively, so that the slide 4 can also be covered by the back cover 1b when it slides out.

[0039] It should be noted that in the description of the present invention, all directional indications (such as up, down, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0040] In addition, in the description of the present invention, "several" and "multiple" mean at least two, such as two, three, etc., unless otherwise clearly defined. It should also be noted that, unless otherwise clearly defined and defined, the terms "set" and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.
