With such a structure, it is convenient to install the air pumping device 4 and also convenient for the air pumping device 4 to communicate with the back massage airbag 31, the lumbar support massage airbag 32, and the hip massage airbag 61.

[0039] Please refer to Figure 1 , the electric chair further includes a leg rest 7, and the leg rest 7 is used to support the user's legs. Please refer to Figure 3 and Figure 4 , the base 1 includes a base plate 11, a bottom frame 12, a seat plate 13, a driving mechanism 14, and a linkage hinge mechanism 15.

[0040] The base plate 11 is used to be placed on the ground to support other components of the electric chair. The bottom frame 12 is mounted on the base plate 11, the seat plate 13 is mounted on the bottom frame 12, and the seat cushion 5 is mounted on the upper end surface of the seat plate 13 for the user to sit on. The driving mechanism 14 is mounted on the bottom frame 12 and located below the seat plate 13. The driving mechanism 14 is used to drive the linkage hinge mechanism 15 to extend or contract.

The backrest 2 is mounted at the rear end of the linkage hinge mechanism 15, and the backrest 2 is used for the user's back to lean on and support the user's upper body during use. The driving mechanism 14 can drive the linkage hinge mechanism 15 to extend or contract. When the driving mechanism 14 drives the linkage hinge mechanism 15 to extend, the linkage hinge mechanism 15 can drive the leg rest 7 to lift and at the same time increase the inclination angle of the backrest 2, so that the leg rest 7 can support the user's legs and the backrest 2 can support the lying user. By setting the driving mechanism 14 or setting the linkage hinge mechanism 15, the effect of a "zero gravity" sofa can be achieved. The structural settings of the driving mechanism 14 and the linkage hinge mechanism 15 can realize the simultaneous adjustment of the backrest 2 and the leg rest 7 by one driving source, which can greatly simplify the structure of the electric chair.

[0041] Please refer to Figure 6, the linkage hinge mechanism 15 includes a connecting crossbar 151, a left hinge assembly 152 and a right hinge assembly 153.

The connecting crossbar 151 is connected to the output end of the driving mechanism 14, and both ends are respectively connected to the left hinge assembly 152 and the right hinge assembly 153. The driving mechanism 14 can push or pull the connecting crossbar 151 forward or backward. When the driving mechanism 14 pushes the connecting crossbar 151 forward, the left hinge assembly 152 and the right hinge assembly 153 extend synchronously, thereby lifting the leg rest 7 and increasing the tilt angle of the backrest 2. When the driving mechanism 14 pulls the connecting crossbar 151 backward, the left hinge assembly 152 and the right hinge assembly 153 contract synchronously, thereby retracting the leg rest 7 and reducing the tilt angle of the backrest 2. By providing the left hinge assembly 152 and the right hinge assembly 153, the adjustment of the leg rest 7 and the backrest 2 is made smoother and more stable. Through the connecting crossbar 151, the synchronous adjustment of the left hinge assembly 152 and the right hinge assembly 153 can be achieved, and only one driving mechanism 14 needs to be provided, which not only reduces costs but also improves synchronism. The connecting crossbar 151 can also improve the structural stability of the left hinge assembly 152 and the right hinge assembly 153, ensuring the stability of the sofa adjustment.
