As shown in FIG. 4 and FIG. 12, the driving mechanism 20 inputs power to the shifting mechanism 30 to drive the hub 34 of the shifting mechanism 30 to rotate. During the rotation of the hub 34, the lever 13 of the operating mechanism 10 can be pulled. The control block 12 is further driven by the control block 12 to slide along the central axis 11 to switch different gear positions and generate different rotational speeds; as shown in FIG. 4, when the drive mechanism 20 is created by the present invention When the toothed disc 22 is used as a power source, the connecting member 23 slides on the coupling member 21 through the action of the mechanical clutch 25, so that the motor engaging structure 235 of the connecting member 23 and the first outer rotor motor 24 are The engaging structure 2411 of the cover 241 is disengaged, so that the outer rotor motor 24 is not driven when the toothed disc 22 rotates, causing the outer rotor motor 24 to generate electricity due to the change of the magnetic pole, causing damage to the outer rotor motor 24, the mechanical clutch When the power is input to the toothed disc 22, the external rotor motor 24 can be protected.

As shown in FIG. 4, when the toothed disk 22 is used as the power input source and the speed control sliding sleeve 141 is in the first gear position, the power input by the toothed disk 22 is transmitted to the sleeve transmission group 31. transmission The sleeve 311 is further transmitted to the ring gear 321 of the ring gear set 32 by the second clutch assembly 312 of the sleeve drive set 31, as shown in FIG. 4 and FIG. 6, at which time the ring of the speed control sleeve 141 is abutted. The rim 1415 abuts against the abutting ends 3222 of the two clamping blocks 322 of the ring gear set 32, so that the two engaging ends 3221 of the engaging blocks 322 are disengaged from the engaging block tooth faces 342 of the hub 34, so the ring The gear set 32 does not directly drive the hub 34 to rotate. At this time, the first clutch assembly 142 mounted on the speed control sleeve 141 is restricted by the first planetary arm 331 of the planetary gear set 33, and thus the transmission is performed. The power transmitted from the sleeve 311 is transmitted to the second planetary arm 332 through the planetary gear 334, and is coupled to the second ratchet arm 332 and the third ratchet portion 343 of the hub 34.

When power is transmitted to the output of the ring gear 321 via the three planetary gears 334, a speed increasing effect is generated and the output speed is greater than the input speed. At this time, the rotation speed of the ring gear 321 is greater than the rotation speed of the transmission sleeve 311 and the planetary gear set 33, so that the second clutch assembly 312 and the second ratchet surface 3213 of the ring gear 321 and the third clutch assembly 335 with the hub 34 The third ratchet portion 343 falls off due to the backward rotation speed, resulting in so-called overrunning characteristics.

As shown in FIG. 12, when the outer rotor motor 24 is used as the power input source and the speed control sleeve 141 is in the first gear position, the mechanical clutch 25 is actuated to cause the connecting member 23 to be in the coupling member 21. Upward sliding, the motor engaging structure 235 of the connecting member 23 and the engaging structure 2411 of the first cover 241 of the outer rotor motor 24 are engaged with each other, and power is transmitted from the outer rotor motor 24 to the outer connecting shaft 21 via the coupling member 21 The transmission sleeve 311 that is engaged with the toothed disc 22 is then transmitted to the ring gear 321 , transmitted to the second planetary arm 332 through the planetary gear 334 , and finally mounted by the second planetary arm 332 . The third clutch assembly 335 is delivered to the hub 34.

As shown in FIG. 13 , when the outer rotor motor 24 is used as the power input source and the speed control sliding sleeve 141 is in the second gear position, the elasticity of the speed control sliding sleeve 141 and the coupling member 21 is abutted. The piece 15 is compressed, and the power is input by the outer rotor motor 24, and then transmitted to the ring gear 321 by the coupling member 21, the toothed disc 22 and the transmission sleeve 311, and finally transmitted to the ring block 322 through the two clamping blocks 322. The hub 34.

As shown in FIG. 14, when the outer rotor motor 24 is used as the power input source and the speed control sleeve 141 is in the third gear position, the power is transmitted from the outer rotor motor 24 via the coupling member 21, the chainring 22 is transmitted to the transmission sleeve 311, and then transferred to the ring gear 321 . Similarly, due to the overspeed characteristic, the second clutch assembly 312 and the third clutch assembly 335 are detached due to the backward rotation speed. Power is transmitted to the hub 34 via the two snap blocks 322.

The integrated gear shifting motor with the three-speed shifting function directly combines the driving mechanism 20 with the shifting mechanism 30, and since the power of the driving mechanism 20 is directly transmitted to the shifting mechanism 30, the energy can be reduced. Unnecessary wear and tear occurs during the process, which not only has the effect of energy saving but also extends the endurance of the outer rotor motor 24 of the drive mechanism 20.
