[0023] Example

[0024] Depend on Figures 1 to 5As shown, an embodiment of the utility model provides an electric rocking chair mechanism, including a backrest iron frame 1, a front rotating connecting frame 2, a rear rotating connecting frame 3, a bottom seat 4, a beautiful leg assembly 5, a connecting rod pushing frame 6 and a driving device 7. The backrest iron frame 1 is hinged to the bottom seat 4 through the front rotating connecting frame 2 and the rear rotating connecting frame 3, so that it can swing back and forth on the bottom seat 4. The fixed end 71 of the driving device 7 is hinged to the bottom seat 1, and the driving end 72 is hinged to the backrest iron frame 1, thereby driving the backrest iron frame 1 to swing back and forth on the bottom seat 4; the beautiful leg assembly 5 is hinged to the front end of the backrest iron frame 1, one end of the connecting rod pushing frame 6 is hinged to the front rotating connecting frame 2, the middle part is hinged to the backrest iron frame 1, and the other end rolls and abuts against the beautiful leg assembly 5, so that when the backrest iron frame 1 swings, it can push the beautiful leg assembly 5 through the action of the connecting rod, so that the beautiful leg assembly 5 can achieve synchronous swinging.

[0025] The bottom seat 4 includes a first support rod 41 and a second support rod 42 arranged in parallel, the front rotating connecting frame 3 and the rear rotating connecting frame 4 are both hinged to the first support rod 41 and the second support rod 42, and a plurality of reinforcing connecting rods 43 are connected between the first support rod and the second support rod to strengthen the stability of the bottom seat 4. An articulated frame 11 is provided at the bottom of the front end of the backrest iron frame 1, and the driving device 7 uses an electric push rod, the fixed end of the electric push rod is hinged at the middle position of one of the reinforcing connecting rods 43 on the rear side, and the telescopic end is hinged at the middle position of the articulated frame 11, so that the electric push rod is located at the middle position of the first support rod 41 and the second support rod 42, and is parallel to the two support rods, so that the electric push rod can push the backrest iron frame 1 to swing back and forth when it is continuously extended and retracted, achieving the effect of a rocking chair, and when the electric push rod stops extending and retracting, it can provide a stable and reliable supporting force for the backrest iron frame.

[0026] Reference Figures 2 to 5 As shown, a hinge 12 is provided at one side of the front end of the backrest iron frame 1, and a Y-shaped hinge 21 is provided at the upper end of the front rotating connecting frame 2. One end of the Y-shaped hinge 21 is used to hinge the connecting rod lifting frame 6, and the other end is used to hinge the backrest iron frame 1. The connecting rod lifting frame 6 includes a first connecting rod 61, a second connecting rod 62 and a third connecting rod 63. One end of the first connecting rod 61 is hinged on the Y-shaped hinge 21 near the hinge 12, and is hinged on the end of the Y-shaped hinge 21 facing the beautiful leg assembly 5; the other end of the first connecting rod 61 is hinged to the second connecting rod 62, the second connecting rod 62 and the third connecting rod 63 are arranged opposite to each other, and are hinged on the hinge 12 through a rotating shaft 65. A roller 64 is connected between the ends of the second connecting rod 62 and the third connecting rod 63, which is used to roll and abut with the beautiful leg assembly 5. By providing the second connecting rod 62 and the third connecting rod 63, the thrust can be made more stable. The second connecting rod 62 is bent at the lower end toward the third connecting rod 63, so that the distance between the second connecting rod 62 and the third connecting rod 63 is wider at the upper end and narrower at the lower end, and the spacing at the lower end is close to the width of the roller 64 to prevent the roller from lateral displacement.

[0027] When the electric push rod is extended, one end of the first connecting rod 61 hinged by the Y-shaped hinge part rotates downward around one end of the hinged backrest iron frame 1, pulling the first connecting rod 61, so that the angle between the first connecting rod 61 and the second connecting rod 62 is opened, and the roller 64 at the end of the second connecting rod 62 rolls upward to push up the beautiful leg assembly 5. When the electric push rod is retracted, one end of the first connecting rod 61 hinged by the Y-shaped hinge part rotates upward around the hinged backrest iron frame 1, pushing the first connecting rod 61, so that the angle between the first connecting rod 61 and the second connecting rod 62 is reduced, and the roller 64 at the end of the second connecting rod 62 rolls downward, and the beautiful leg assembly 5 swings downward, thereby realizing the synchronous swinging of the beautiful leg assembly 5 and the backrest iron frame 1, increasing the fun of using the massage rocking chair and enhancing the user's massage experience.

[0028] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
