[0009] The damping rocker arm is installed on the base through the damping rocker arm shaft pin, and the damper is fixed to the base through the damper mounting screws. The damping rocker arm is provided with a damping rocker arm transmission component, and the damper is provided with a damper transmission component. The damping rocker arm transmission component and the damper transmission component cooperate with each other to form a rotational fit between the damping rocker arm and the damper, and the damping rocker arm forms a sliding fit with the cylindrical pin shaft of the lever on the outer edge of the mechanical reset lever.

[0010] The rotary hidden handle with automatic slow return damping is characterized by:

[0011] The transmission parts of the damping rocker arm and the damper are both gears, sprockets or pulleys.

[0012] When the damping rocker arm transmission part and the damper transmission part are both gears, the damping rocker arm transmission part and the damper transmission part are meshed with each other.

[0016] The method for using the rotary hidden handle with a mechanical automatic slow reset damping mechanism is characterized by: including ejection and retraction:

[0017] Pop-up: When the hidden handle is in the retracted state, after receiving the pop-up command, the mechanical reset lever rotates forward to tighten the torsion spring of the mechanical reset lever. When the mechanical reset lever rotates forward, on the one hand, the cylindrical pin of the lever drives the damping rocker arm and the damping rocker arm transmission part to rotate through the rocker arm slot, and the damping rocker arm transmission part drives the damper transmission part and the damper to rotate, and the damper has a damping effect on the rotation; on the other hand, the U-shaped groove of the lever drives the cylindrical pin of the handle to drive the hidden handle to pop out;
