1results about How to "High braking torque" patented technology

This invention provides a locking structure for a hub motor, a hub motor, and an electric device, including: a rotating component, a connecting seat, a locking tongue, and a locking actuation unit; the rotating component is connected to the motor rotor assembly of the hub motor and rotates with the motor rotor assembly, and includes multiple slots; the connecting seat is connected to the motor stator assembly of the hub motor; the locking tongue is rotatably connected to the connecting seat, and the locking actuation unit is connected to the connecting seat and driven by the locking tongue, enabling the locking tongue to rotate, thereby extending into or retracting from a slot. This invention achieves locking and unlocking by engaging the locking tongue with the slots of the rotating component, thus realizing braking of the hub motor. The overall structure is compact and occupies little space, providing sufficient braking torque when locked to meet actual operating conditions.
