This application discloses an electronically controlled moving chainring mechanism, a shifting system, and a bicycle. The bottom bracket is installed in a cylinder body and is fixed circumferentially to the bushing. The piston is detachably connected to the bushing. When the pedal drives the bottom bracket to rotate, the bottom bracket drives the bushing to rotate, which in turn drives the chainring to rotate. When the freewheel shifts gears, the electronically controlled drive mechanism can actively drive the piston to move axially, and drive the bushing and chainring to adjust their positions synchronously, thereby reducing the angle between the chain, chainring, and freewheel, and improving riding efficiency. Furthermore, the reduced angle expands the meshing range between the chain and the teeth, reducing chain slippage, asymmetrical wear, and axial stress, lowering the risk of tooth deformation, and extending the service life of components. Compared to the traditional passive adjustment method of the chain driving the chainring, this embodiment actively controls the chainring movement through an electronically controlled drive mechanism, resulting in smoother and more precise chainring movement, avoiding jamming, and ensuring stable positioning after reaching the correct position, thus improving riding stability.

This application discloses a direct-drive chainring mechanism and a bicycle. By placing a linear motor between the frame and the bottom bracket, and fitting the motor rotor onto the bottom bracket to allow it to move axially along the bottom bracket, and connecting a bushing fitted onto the bottom bracket to the motor rotor, the chainring can be moved synchronously along the bottom bracket axially by controlling the working state of the motor stator. This adjusts the angle between the chainring and the chain, reducing the deviation of the angle from the ideal zero degree, decreasing the axial component force generated by the angle when the chain transmits driving force, increasing the effective power to drive the freewheel, and ultimately improving riding efficiency. This embodiment of the application provides a reliable path for optimizing the power transmission efficiency of a multi-speed bicycle by utilizing the linkage mechanism between the linear motor and the chainring. Furthermore, because the angle is smaller, the meshing range between the chain and the teeth is wider, reducing chain slippage, asymmetrical wear of the teeth, and axial force on the teeth.
