Automatic lifting device and bicycle system based on riding status

Abstract

This invention relates to an automatic lifting device and bicycle system based on riding status, mainly used for automatically adjusting the extension and positioning of the seat post, etc. It uses an electronic device to detect control command signals such as vehicle speed or external signals. After calculation, the electronic device outputs a positioning command to a processing module via a communication interface. The processing module then uses a ranging module to detect the extension and retraction of the seat post, etc., and outputs a feedback signal. The processing module receives the control command signal and the feedback signal, performs calculations, outputs a positioning command signal, and determines whether it is equal to the feedback signal. If they are not equal, an actuation signal is generated. A valve control module executes the actuation signal and drives the extension and retraction of the extension component until the feedback signal and the positioning command signal are equal.
