A speed reducer structure with a disengaging mechanism comprises a motor (1), a speed reducing mechanism (3), an output mechanism (4), the disengaging mechanism (5) and a shell (6). The speed reducing mechanism (3) comprises a sun gear (31), a plurality of duplex planet gears (32), a gear ring (33), a planet shaft (34) and a planet carrier (35); a motor shaft (2) of a motor (1) is connected with a sun gear (31), the sun gear (31) is meshed with a large gear (321) of a duplex planet gear (32), the duplex planet gear (32) is arranged on a planet shaft (34) in a sleeved mode, the planet shaft (34) is connected with a planet carrier (35), the planet carrier (35) and a shell (6) are integrally formed, and a small gear (322) of the duplex planet gear (32) is meshed with a gear ring (33). The disengaging mechanism (5) is arranged between the shell (6) and the gear ring (33) and used for achieving transmission or disengaging of motor power through the output mechanism (4) by braking or loosening the gear ring (33). The device is compact in structure, good in carrying performance and capable of being separated from power of the whole vehicle, power consumption is saved, and the endurance mileage is increased. A vehicle is also disclosed.
