The second driving assembly 90 includes a second driving square tube 93, a fourth connecting member 92 fixed at two ends of the second driving square tube 93, and a fifth connecting member 91 fixed on the second driving square tube 93, the fourth connecting member 92 is fixedly connected with the backrest assembly 80, and the second driving mechanism 70 is rotatably connected with the fifth connecting member 91 and drives the second driving assembly 90 to rotate or move.
In the present embodiment, the first driving mechanism 10 and the second driving mechanism 70 include, but are not limited to, driving motors, and may be replaced by other linear driving methods, and the support frame 20 may be replaced by other non-complete components through a combination method.
The connection and action relationships between the components of the present embodiment will now be further described in conjunction with the transitions between the operational states, including but not limited to a sitting position, a walking position, a standing position, a back-open and leg-closed position, and a TV position.
In the present embodiment, when the chair is in the sitting posture (see fig. 1, 2 and 3), the second driving mechanism 70 is in the completely pushed-out state, the backrest angle is in the normal sitting posture state, and when the chair is in the current posture, the first driving mechanism 10 is in a certain middle position, that is, the first driving mechanism 10 can be continuously retracted to open the legs, and can also be continuously pushed forward to lift the support frame 20; when the first driving mechanism 10 continues to retract, the third connecting rod 33 drives the leg driving connecting rod 32 to rotate and move, the leg driving connecting rod 32 drives the leg telescopic connecting rod 31 to rotate and move, the leg telescopic assembly 30 is opened, and the leg telescopic assembly 30 reaches the state shown in the drawing 4; when the first driving mechanism 10 continues to advance forward, the first driving assembly 40 drives the leg stretching assembly 30 upward, the leg stretching assembly 30 further drives the stand frame 20 to lift upward, and the stand frame 20 reaches the position shown in the standing state of fig. 6.
