Title:
MID-DRIVE MOTOR USING DYNAMIC SENSOR CIRCUIT COMBINATION
Document Type and Number:
WIPO Patent Application WO/2019/091180
Kind Code:
A1
Abstract:
A dynamic sensor circuit combination and a mid-drive motor using the circuit combination. The circuit combination comprises a transmission feedback circuit and a reception and collection circuit. The mid-drive motor comprises a drive device (1) and a linkage device (2). The drive device (1) drives the linkage device (2). The linkage device (2) comprises a gearbox (21), a middle shaft (25), and a protective housing (27). The gearbox (21) is fixedly connected to the protective housing (27). The middle shaft (25) is placed in the protective housing (27). A torsion housing (26) is sleeved on the middle shaft (25). The torsion housing (26) is fixedly connected to the middle shaft (25). The transmission feedback circuit is disposed on the inner wall of the protective housing (27). The reception and collection circuit is disposed on the torsion housing (26). By using a bottom bracket of a general vehicle frame, a bicycle rider can mount the mid-drive motor using the dynamic sensor circuit combination in a DIY manner, and the general bicycle is refitted into an electric bicycle; and the mid-drive motor using the dynamic sensor circuit combination can also be used for mass production and mounting in an electric bicycle manufacturing plant.
