[0038] Further, refer to Figures 3 to 7 The stretching and swinging mechanism includes: a cradle 21, two connecting arms 23, a leg support frame 3, a back support frame 4, a first transmission assembly 6, and a transmission rod 32; the cradle 21 is rocked on the mounting frame 13, the two connecting arms 23 are respectively arranged at the two ends of the cradle 21, the connecting arms 23 are rotatably connected to the cradle 21, the leg support frame 3 is rotatably connected to one end of the connecting arm 23, a leg connecting rod 31 is arranged between the two leg support frames 3, the back support frame 4 is rotatably connected to the other end of the connecting arm 23, the first transmission assembly 6 is arranged on the cradle 21, and the first transmission assembly 6 The output end is rotationally connected to the leg connecting rod 31, and the first transmission assembly 6 is used to drive the leg connecting rod 31 to approach or move away from the connecting arm 23, so that the leg connecting rod 31 drives the leg support frame 3 to retract or extend. One end of the transmission rod 32 is rotationally connected to the other end of the connecting arm 23, and the other end of the transmission rod 32 is rotationally connected to the leg support frame 3. The transmission rod 32 is used to drive the other end of the connecting arm 23 to press down when the leg support frame 3 is extended, so that the center of gravity of the cradle 21 moves forward, so that the center of gravity of the cradle 21 is maximized and maintained within the range of the center of gravity of the cradle 21 that can be rocked.

[0039] In this embodiment, the first transmission component 6 pushes the leg connecting rod 31 away from the connecting arm 23. At this time, the leg connecting rod 31 drives the transmission rod 32 to move forward to open the leg support frame 3. At the same time, the forward-moving transmission rod 32 pulls the other end of the connecting arm 23 to tilt downward. Under the action of the center of gravity of the person sitting on the rocking chair, the inclined connecting arms 23 drive the person to move slightly forward, and the center of gravity of the person is shifted to the interval within the rocking range of the rocking frame 21, so that when the rocking chair enters a non-sitting state, there is still a certain rocking space. In addition, when the rocking chair is in a non-sitting state, the rocking effect can still be achieved. In terms of structure, only the first transmission component 6 is used to drive the leg connecting rod 31, so that the leg connecting rod 31 drives the leg support frame 3 to be retracted or extended, thereby reducing the complexity of the structure and reducing the manufacturing cost. In addition, due to the reduction of the complex linkage structure, the traction force generated by the linkage structure on the first transmission component 6 is reduced, thereby reducing the loss of the first transmission component 6 and improving the service life of the first transmission component 6.

[0040] A first link plate 211 is fixedly installed at both ends of the cradle 21, one end of the first link plate 211 is rotatably connected to the first connecting rod 212 at the first connection point 2111, one end of the first connecting rod 212 is rotatably connected to one end of the connecting arm 23 at the second connection point 231, the other end of the first link plate 211 is rotatably connected to the second connecting plate 213 at the third connection point 232, the middle of the second connecting plate 213 is connected to the other end of the first link plate 211, one end of the second connecting plate 213 is rotatably connected to the other end of the connecting arm 23 at the fourth connection point 233, and the other end of the second connecting plate 213 is rotatably connected to one end of the transmission rod 32 at the fifth connection point 321 is rotatably connected; the leg support frame 3 includes: a first guide rod 33, a fourth guide rod 36, and a fifth guide rod 37; one end of the first guide rod 33 is rotatably connected to one end of the connecting arm 23 at the eighth connection point 331, one end of the fourth guide rod 36 is rotatably connected to one end of the connecting arm 23 at the ninth connection point 361, the other end of the fourth guide rod 36 is rotatably connected to one end of the fifth guide rod 37, the first guide rod 33 is rotatably connected to the fifth guide rod 37 at the eleventh connection point 371, the other end of the transmission rod 32 is rotatably connected to the fourth guide rod 36 at the tenth connection point 322, and the leg connecting rod 31 is fixedly connected to the first guide rod 33 at the sixteenth connection point 332.

[0041] In this embodiment, when the first transmission assembly 6 drives the leg connecting rod 31 away from the connecting arm 23, the leg connecting rod 31 pushes the first guide rod 33, so that the first guide rod 33 drives the fifth guide rod 37 to move, and the moving fifth guide rod 37 drives the fourth guide rod 36 to move. In this process, the moving fourth guide rod 36 pulls the transmission rod 32 forward, and the forward-moving transmission rod 32 drives the second connecting plate 213 to rotate around the third connecting point 232 as the axis, so that the second connecting plate 213 drives the other end of the connecting arm 23 to move downward, so as to adjust the center of gravity of the person on the rocking chair so that the rocking chair can enter a non-sitting position. The rocking chair can still be rocked in this state. At the same time, when the first transmission component 6 drives the leg support frame 3 to move, the center of gravity of the person on the rocking chair is adjusted according to the movement amplitude of the leg support frame 3, so that the center of gravity of the person on the rocking chair is adjusted more accurately, and the phenomenon of the rocking chair tipping over caused by the deviation of the center of gravity is prevented, thereby improving the stability of the rocking chair. At the same time, the transmission rod 32 is used to adjust the angle of the connecting arm 23, so as to achieve the effect of adjusting the center of gravity, which greatly reduces the complexity of the linkage structure, thereby reducing the traction force on the first transmission component 6, and further improving the service life of the first transmission component 6.

[0042] The back support frame 4 includes a plug-in plate 41, which is T-shaped. One end of the plug-in plate 41 is rotatably connected to the other end of the connecting arm 23 at the sixth connection point 411. Among the other two ends of the plug-in plate 41, one end is used for plugging into the rear back support frame, and the other end is fixedly connected to a connecting rod 42 at the seventh connection point 412.

[0043] In this embodiment, two support rods 22 are fixedly installed in the middle of the rocking frame 21, and the first transmission assembly 6 and the second transmission assembly 7 are respectively installed on the two support rods 22. When the rocking frame 21 is rocking, the first transmission assembly 6 and the second transmission assembly 7 are driven to rock at the same time. Therefore, the power output of the first transmission assembly 6 and the second transmission assembly 7 is not affected by the rocking of the rocking frame 21. The second transmission assembly 7 is used to adjust the angle of the rear backrest support frame to achieve the backward tilt of the rear backrest to adjust the supine angle of the upper body of the person on the rocking chair.

[0044] The side of the mounting frame 13 that contacts the cradle 21 is a horizontal plane, which is arranged on the mounting frame 13; the side of the cradle 21 that contacts the mounting frame 13 is an arc surface, which is arranged on the cradle 21; the mounting frame 13 and the cradle 21 are connected by two rows of elastic members, which are arranged at intervals; a limit block 8 is provided at the other end of the connecting arm 23, and the limit block 8 is used to limit the shaking amplitude of the cradle 21.

The two springs 14 are respectively located at the front and rear ends of the arc surface, one end of the spring 14 is fixedly connected to the support rod 22, and the other end of the spring 14 is fixedly connected to the mounting frame 13. The spring 14 is used to fix the cradle 21 and give the cradle 21 a certain compression space so that the cradle 21 can achieve the rocking function. During the extension of the leg support frame 3, the transmission rod 32 pulls the connecting arm 23 to adjust the center of gravity as close as possible to the middle of the two springs 14, so that the rocking chair still has a certain rocking space when it is not in a sitting state. Until the rocking chair is in a lying state, the spring 14 at the rear end is completely compressed, and the rocking chair loses its rocking function. At this time, the limit block 8 conflicts with the mounting frame 13 to achieve a supporting effect to prevent the rocking chair from tipping over.
