Abrégé

A novel drive structure, comprising a drive wheel assembly. The drive wheel assembly comprises at least two wheel components arranged at an interval, and further comprises a drive rope (2), a plurality of drive blocks (3) being provided on the drive rope (3), and the drive rope (2) being wound sequentially around the wheel components to form an open loop structure or a closed loop structure. The present drive structure features a compact and reasonable structure, low drive noise, and is suitable for use in synchronous drives having torsion, such as in driving scenarios in such fields as the driving of electric doors or windows, industrial devices, household appliances, or household products. The structure is stable, and markedly reduces costs.

Abrégé

A Hall-type run-length limited self-resetting coding device for a garage gate machine comprises a nylon turbine (5), a driving motor (1) for driving the nylon turbine (5) to rotate, a motor rotation counting limit mechanism for carrying out rotation counting limit on a rotor shaft of the driving motor (1), and a turbine counting calibration mechanism for calibration of the driving motor's (1) limited run-time. The turbine counting calibration mechanism comprises a turbine magnet (4) arranged on the nylon turbine (5) and a turbine position Hall element (9) adapted to the turbine magnet (4). The device is compact in structure and can effectively limit the limit deviation of a garage gate.
