Stabilizing device of elevator car and a control method thereof, an elevator system

A damper of an elevator car, comprising:

• a base fixedly mounted with respect to the elevator car;
• a clamping mechanism used for clamping a guide surface of a guide rail to generate a friction (Ffriction) for preventing the elevator car from moving, the clamping mechanism mainly comprising two clamp arm components;
• a solenoid drive part at least used for providing the clamp arm components with a force for clamping the guide surface of the guide rail, the force from the solenoid drive part applied to both the clamp arm components;
• and
• a link transmission component disposed between the solenoid drive part and the clamping mechanism,
• wherein the link transmission component is configured to be movable in a direction approximately perpendicular to the guide surface and drive at least one of the two clamp arm components connected thereto to move towards the guide rail.
