[0010] A lifting chair includes a seat lifting frame 1, a driving mechanism 2, and a support seat 3. The driving mechanism 2 includes an electric driving part 4 and a driven part 5. The electric driving part 4 and the seat lifting frame 1 pivot in a vertical direction relative to the support seat 3. The driven part 5 and the seat lifting frame 1 pivot in a vertical direction relative to the support seat 3. The electric driving part 4 and the driven part 5 are arranged on the support seat 3. The driving mechanism 2 also includes a driven rod 6. The electric driving part 4 and the driven part 5 pivot in a horizontal direction relative to the support seat 3 through the driven rod 6. The electric driving part 4 includes a motor 7, a motor Output shaft 8, rotating member 9, driving member 10, the motor output shaft 8 is fixedly connected with rotating member 9, rotating member 9 and driving member 10 pivot, the rotating member 9 and driving member 10 pivot point deviates from the fixed point of rotating member 9 and motor output shaft 8, driven part 5 includes rotating shaft 11, driven rotating member 12, driven driving member 13, the rotating shaft 11 is fixedly connected with driven rotating member 12, driven rotating member 12 pivots with driven driving member 13, the pivot point of driven rotating member 12 and driven driving member 13 deviates from the fixed point of driven rotating member 12 and rotating shaft 11. When motor 7 rotates continuously, electric driving part 4 drives driven part 5 to drive seat lifting frame 1 to continuously rise and fall reciprocatingly relative to support seat 3. The motor output shaft 8 is pivoted on the support seat 3, the rotating member 9 is fixed thereto, one end of the driving member 10 pivots with the rotating member 9, and the other end pivots with the seat body lifting frame 1, and at the same time, the rotating shaft 11 of the driven part 5 pivots with the support seat 3, the driven rotating member 12 and one end of the driven driving member 13 pivot, and the other end of the driven driving member 13 pivots with the seat body lifting frame 1, and the electric driving part 4 drives the driven part 5 to drive the seat body lifting frame 1 to rise and fall.
