Abstract
A transmission structure of a mid-drive motor has a shell, an output axle, a motor unit, and a clutch assembly. The clutch assembly has a driving ring, a clutch gear, an output gear, and a pressing device. The driving ring is connected to the motor unit. The output gear is connected to the output axle and is detachably connected to the clutch gear. The pressing device has a base casing, a pressing disc, and an elastic unit. The pressing disc moves axially in the base casing, and the elastic unit abuts the pressing disc and the base casing. The clutch gear drives the pressing disc to rotate, and the pressing disc pushes the clutch gear to engage with the output gear. The elastic unit and the pressing device reset the pressing disc, and the pressing device resets the clutch gear after the clutch gear separating from the output gear.
