Electrically controlled chassis and chair

A chair, comprising an electrically controlled chassis, wherein the electrically controlled chassis is applicable to adjustment of a chair, and the electrically controlled chassis comprising:

• a chassis body;
• an electrical control box, disposed on the chassis body, and internally provided with an accommodation space;
• a drive motor, disposed in the accommodation space of the electrical control box, and configured to control lift adjustment of the chassis of the chair and pitch adjustment of a backrest of the chair;
• a winding mechanism, connected to an output shaft of the drive motor, and being rotatable with the output shaft of the drive motor;
• a first pull cord, wound on the winding mechanism along a first direction, and one end of the first pull cord being fixedly connected to the winding mechanism;
• a second pull cord, wound on the winding mechanism along a second direction, and one end of the second pull cord being fixedly connected to the winding mechanism;
• wherein the first direction and the second direction are opposite directions;
• a backrest adjustment mechanism, disposed on the chassis body, and fixedly connected to the other end of the first pull cord, wherein when the output shaft of the drive motor drives the winding mechanism to rotate along a first direction, the first pull cord is pulled such that the backrest adjustment mechanism is adjustable;
• and
• a chassis lift mechanism, disposed on the chassis body, and fixedly connected to the other end of the second pull cord, wherein when the output shaft of the drive motor drives the winding mechanism to rotate along a second direction, the second pull cord is pulled such that the chassis lift mechanism is adjustable.
