In another embodiment, the configuration and structure of the driving device can be adjusted to directly or indirectly drive the first rack 4B to move up and down, unlike the driving device directly or indirectly driving the second rack 4C to move up and down.
In another embodiment, the configuration and structure of the driving device can be adjusted to realize the reverse movement of the first rack and the second rack by the way that the driving device drives the gear member 4A to rotate forward and backward, which is different from the way that the driving device directly or indirectly drives the first rack 4B or the second rack 4C to move up and down.
In another embodiment, the driving device may not be configured, and the foot rest may be moved downward by pressing the foot massage structure with the user's foot, and the second rack 4C is driven to move downward. Meanwhile, the lower limb massager can also comprise a spring element, and two ends of the spring element are connected between the fixing frame 1, the leg frame 2 and the foot frame 3 to play a role in resetting.
In another embodiment, the manner of fitting the fastening frame 1, the leg frame 2, and the foot frame 3 may not be limited to the structure of the first embodiment.
In another embodiment, the gear member 4A may be directly disposed on the fixing frame, instead of being indirectly disposed on the fixing frame through the gear member disposition plate 4D.
The present application further provides a massage chair, comprising a seat frame and a lower limb massager hinged to the front end of the seat frame, wherein the lower limb massager may be the lower limb massager of any of the above embodiments.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
