[0005] A fall-proof multifunctional chair comprises a bottom support frame, a driving wheel is arranged at the bottom of the bottom support frame, the driving wheel is driven by a driving motor, a guide wheel frame is rotatably arranged at the bottom front end of the bottom support frame, a guide wheel is rotatably arranged in the guide wheel frame, a column is fixedly arranged on the bottom support frame, the upper end of the column is hinged to the bottom support frame, a seat cushion is fixedly arranged on the bottom support frame, a backrest is hingedly arranged on one side of the seat cushion, and an armrest is hingedly arranged on the side of the backrest.

[0006] In a preferred embodiment, a pedal support arm is hingedly provided at the front end of the bottom support frame, and a foot pedal is hingedly provided on the pedal support arm.

[0007] In a preferred embodiment, the bottom support frame and the column are hinged via a ball head, and four linear electric push rods are also hinged between the bottom support frame and the column via a double ball head.

[0008] In a preferred embodiment, the linear electric push rods are distributed at the four corners of a square.

[0009] In a preferred embodiment, a power supply and a controller for supplying power to the linear electric push rod are fixedly provided on the bottom support frame.

[0010] In a preferred embodiment, a bottom storage box opening rearward is provided on the bottom support frame for storage.

[0011] In a preferred embodiment, a pushing rod is welded and fixed on the bottom support frame for facilitating pushing.

[0012] The advantages and positive effects of the present invention are: by decoupling the chassis and the bottom support structure of the seat cushion, four independently adjustable linear electric push rods can adjust the support surface of the seat cushion when the road surface is uneven, so as to keep it stable and avoid the human body from tilting and becoming unstable and falling.
