The invention relates to an elevator device for automatically adjusting the gravity center balance of a car. The elevator device comprises the car, a balance sensor, at least two liquid storage tanks, a controller and a liquid conveying pump, wherein the balance sensor and the liquid storage tanks are arranged on the car, the controller is electrically connected with the balance sensor, and the liquid conveying pump is electrically connected with the controller. The liquid storage tanks are arranged on the side wall of the car. Each liquid storage tank is provided with a liquid conveying pipe. The liquid conveying pump is provided with connectors in one-to-one correspondence with the liquid conveying pipes. Each connector is provided with a control valve electrically connected with the controller. The balance of the car is detected through the balance sensor, and detection information is sent to the controller. The controller controls the liquid conveying pump to work according to collected information, and controls opening and closing of the control valves on the different connectors and the direction and flow of the liquid conveying pump according to the compensation direction and quantity, so that liquid flows towards the liquid storage tank on the light side of the car through the liquid conveying pipes, and the car is kept balanced. Friction force between a guide shoe and a guide rail is reduced, the comfort for a passenger for taking an elevator is improved, and the service life of the elevator is prolonged.
