Please refer to Fig. 1.The schematic diagram that Fig. 1 is the utility model bicycle driver module.As shown in Figure 1, bicycle driver module 10 of the present utility model comprises the foot-operated driver module 200 of sprocket wheel 400, one a motorized motions module 100,, and a power is selected module 300.The trailing wheel that sprocket wheel 400 can drive the chain drive bicycle when rotating rotates, so that bicycle advances.Motorized motions module 100 comprises a motor 110 in order to outputting power, and a harmonic speed changer 120 is coupled to the output shaft of motor 110, the power of exporting in order to change motor 110.Foot-operated driver module 200 comprises two cranks 210, and an axle drive shaft 220 is coupled between two cranks 210.Power selects module 300 to be coupled to sprocket wheel 400, harmonic speed changer 120 and axle drive shaft 220, in order to the transmission of power of selected harmonic speed reduction gearing 120 and axle drive shaft 220 output wherein, to sprocket wheel 400, with drive sprocket 400, rotates.Power is selected module 300 to comprise a unilateral bearing 310 and is coupled to sprocket wheel 400 and axle drive shaft 220, and a power-transfer clutch 320 is coupled between harmonic speed changer 120 and unilateral bearing 310.
Please also refer to Fig. 2 and Fig. 3, and in the lump with reference to figure 1.The exploded view of the embodiment that Fig. 2 is the utility model harmonic speed changer.The inner structure schematic diagram that Fig. 3 is Fig. 2 harmonic speed changer.As shown in the figure, the utility model harmonic speed changer 120 comprises housing 122, one first gear 124, one second gears 126, and a driver element 130.The first gear 124 has the engaging tooth of one first number.The second gear 126 is fixed on housing 122, and the second gear 126 has the engaging tooth of one second number.The second number is different from the first number.Driver element 130 comprises a load bearing seat 132 and most the 3rd gears 134.The 3rd gear 134 is fixed on load bearing seat 132 in rotating mode, and each the 3rd gear 134 and the first gear 124 and the second gear 126 mesh simultaneously.
In addition, the first gear 124 and the second gear 126 are inner gear, and the 3rd gear 134 is external gear.The reference circle reference diameter of the first gear 124 and the second gear 126 is identical, and the first gear 124 and the second gear 126 have identical line of centers.The reference circle reference diameter of the 3rd gear 134 all is less than the reference circle reference diameter of the first gear 124 and the reference diameter of the second gear 126 reference circles.The first gear 124, the second gear 126 and the 3rd gear 134 are all rigid gear.Load bearing seat 132 can be coupled to the output shaft of motor 110, and the first gear 124 can be coupled to power selection module 300 with outputting power.
According to the above embodiments configuration, can change the engage position of the 3rd gear 134 and first and second gear 124,126 when motor 110 drives load bearing seat 132 to rotate, and then drive the first gear 124 rotations to select module 300 with outputting power to power.For instance, the first number and the second number differ 4, and therefore the 3rd gear 134 can mesh with the first gear 124 and the second gear 126 at interval of 90 degree angle in circular segments simultaneously.When load bearing seat 132 rotates, the 3rd gear 134 can rotate around the inboard of the first gear 124 and the second gear 126, and then changes the engage position of the 3rd gear 134 and first and second gear 124,126.When load bearing seat 132 turns around, because the second gear 126 is fixed on housing 122, do not rotate, and the first gear 124 and the second gear 126 differ 4 engaging tooths, the first gear 124 can rotate relative to the second gear 126 angle in circular segment of 4 engaging tooths.Therefore the reduction ratio of harmonic speed changer 120 is that the engaging tooth number of the first gear 124 is poor divided by the total number of teeth in engagement purpose of the first gear 124 and the second gear 126, when the engaging tooth number of the first gear 124 is more and the engaging tooth number difference of the first gear 124 and the second gear 126 when less, the utility model harmonic speed changer 120 can obtain quite high reduction ratio.
Please also refer to Fig. 4 and Fig. 5.The exploded view that Fig. 4 is the utility model power-transfer clutch, the section-drawing that Fig. 5 is Fig. 4 power-transfer clutch.As shown in the figure, the utility model power-transfer clutch 320 comprises one first gear unit 330, most clutch units 340, and one second gear unit 350.The first gear unit 330 is in order to be coupled to the first gear 124 of harmonic speed changer 120.The first gear unit 330 has most accommodating structures 332.Each accommodating structure 332 comprises a sunk structure 334, and a cylinder 336, and wherein an accommodation space is formed between sunk structure 334 and cylinder 336, with accommodating clutch unit 340.Clutch unit 340 is arranged at respectively on the accommodating structure 332 of the first gear unit 330.The first side of clutch unit 340 has a pushing part 342, and the second side of clutch unit 340 has a kink 344.The second gear unit 350 is arranged at the opposite position of the first gear unit 330, in order to be coupled to unilateral bearing 310.The second gear unit 350 has a driving face 352, is arranged at the inside face of the outer rim of the second gear unit 350, and driving face 352 is around around the first gear unit 330.
According to the configuration of above-described embodiment, the utility model power selects module 300 can select harmonic speed changer 120 and axle drive shaft 220 transmission of power of exporting wherein to sprocket wheel 400, with drive sprocket 400, rotates.For instance, when harmonic speed changer 120 rotates the first gear unit 330, the driving face 352 of clutch unit 340 outside pushing tow the second gear units 350, make the second gear unit 350 along with the first gear unit 330 rotates, be delivered to unilateral bearing 310 with the power by harmonic speed changer 120 via the first gear unit 330 and the second gear unit 350, rotate with drive sprocket 400.On the contrary, when harmonic speed changer 120 does not rotate, clutch unit 340 is the outside driving face 352 of pushing tow the second gear unit 350 not, to allow the second gear unit 350 to rotate with respect to the first gear unit 330, so unilateral bearing 310 can utilize the power driven sprockets 400 of axle drive shaft 220 to rotate.
In addition, the harmonic speed changer of the utility model bicycle driver module and power select module to be not limited to above-described embodiment, and the harmonic speed changer of the utility model bicycle driver module and power select harmonic speed changer and power that module can other types to select module.
Compared to prior art, the harmonic speed changer of the utility model bicycle driver module has quite high reduction ratio to change efficiently the power of motor.In addition, the power of the utility model bicycle driver module selects module to select manpower or motor power according to power input source, to drive efficiently bicycle.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
