[0028] The specific working process and principle of this utility model:

[0029] Lying state: start the first push rod motor, the slider of the first push rod motor drives the translation frame to move outward along the groove guide rail, the translation frame pulls the backrest frame, and under the action of the backrest support rod, the front side of the backrest frame moves outward with the translation frame, and the back side of the backrest frame moves downward. At the same time, the translation frame pushes the leg frame to move outward until the backrest frame is flush with the translation frame and the leg frame. At this time, the back beam falls on the column, and the front side of the backrest connecting rod falls on the rear top surface of the rectangular tube. The backrest frame has sufficient supporting force, the leg connecting rod two is supported by the rectangular tube, and the leg connecting rod one is constrained by the leg connecting rod two and the leg support rod, so as to maintain a stable suspended state and extend out of the front baffle of the sofa frame, which can give people a sense of mystery and add fun to life.

[0030] Reclining state: Based on the lying state, the reverse operation can be performed. The slider of the first push rod motor drives the translation frame to move inward along the grooved guide rail, and the translation frame pushes the backrest frame. Under the action of the backrest support rod, the front side of the backrest frame moves inward with the translation frame, while the rear side of the backrest frame moves upward. At the same time, the translation frame pulls the leg frame to move inward until the backrest frame and the translation frame form a maximum angle. The translation frame and the leg frame are reset. At this time, the backrest support rod contacts the limit pin, thereby improving the state stability of the backrest frame at this time. The leg frame can pass freely above the front baffle of the sofa frame. The front baffle of the sofa frame can be a complete plate to cover the iron parts inside the sofa frame, which is highly aesthetic.

[0031] Reclining and leg-lifting state: in the reclining state, start the second push rod motor, and the telescopic end of the second push rod motor drives the leg link 2 to flip upward, and under the action of the leg support rod, the leg link 1 and the leg link 2 form an arch, and the leg link 2 is used to support the thigh, and the leg link 1 is used to support the calf, which is more ergonomic and improves the comfort of the user when the legs are lifted.

[0032] Zero gravity state: based on the state of reclining with legs raised, the first push rod motor is started to drive the translation frame to move outward, and the angle between the backrest frame and the translation frame is adjusted to a desired angle.

[0033] Lying flat with legs raised: on the basis of the zero gravity state, continue to start the first push rod motor to drive the translation frame to move outward until the backrest frame is flush with the translation frame.

[0034] The utility model has convenient operation, stable and reliable structure, and can provide users with multiple experiences.
