Abstract
A window covering control assembly is used in a window covering system. The window covering control assembly comprises a driving module and a speed control module, and is provided in the shell, engaged to the weight element for simultaneous operation therewith. The driving module comprises a cord collecting assembly mounted in the shell. The cord collecting assembly is configured to operate in a first direction while a first driving force acting upon the cord collecting assembly such that the weight element descends away from the shell. The first driving force comprises at least a weight of the weight element. The speed control module is positioned corresponding to the driving module. A resistance force is selectively generated between the speed control module and the driving module, and this force reduces an operation speed of the cord collecting assembly in the first direction.
