Specifically, the first single direction ratchet 132 and the second single direction ratchet 133 all are incorporated on the hind axle 131.The first single direction ratchet 132 can drive hind axle 131, and the part of the first single direction ratchet 132 can rotate toward a first direction with respect to hind axle 131.The part that the second single direction ratchet 133 can drive hind axle 131, the second single direction ratchet 133 can rotate toward a second direction with respect to hind axle 131.First direction is opposite with second direction.For example, in the utility model preferred embodiment, first direction is clockwise direction, and second direction is anticlockwise direction.In addition, the structure of the first single direction ratchet 132 and the second single direction ratchet 133 and above-mentioned existing single direction ratchet 20 are similar, and detailed start principle will be in following detailed description.
Please continue with reference to figure 3, hold above-mentionedly, also combine chain drum group 134 on the first single direction ratchet 132.Also combine electric motor groups 135 on the second single direction ratchet 133.Chain drum group 134 can drive the first single direction ratchet 132, and chain drum group 134 has a plurality of chain drum 134a, and these chain drums 134a has respectively the different numbers of teeth, the white silk dish 134a that the user can come according to different user demands Self-adjustment to use.Electric motor groups 135 can drive the second single direction ratchet 133.
In this preferred embodiment, rear wheel unit 130 more comprises a wheel rim 136, and wheel rim 136 is fixed on the hind axle 131, and on the wheel rim 136 in conjunction with tire.Drive hind axle 131 by the first single direction ratchet 132 or the second single direction ratchet 133, circle wheel 136 is just rotatable, and then makes tyre rotation.In addition, drive chain drum group 134 in order to allow the user step on mode with pin, electric auxiliary pedal cycle 100 comprises that more a crank group 140(please refer to Fig. 2), in order to drive this chain drum group 134.
Although be noted that in preferred embodiment of the present utility model, first direction is clockwise direction, and second direction is anticlockwise direction.Yet the utility model does not limit above-mentioned rotation direction, and in a further embodiment, first direction can be anticlockwise direction, and second direction is clockwise direction.In addition, in the present embodiment, the first single direction ratchet 132 and the second single direction ratchet 133 are positioned at the not homonymy of wheel rim 136.But the utility model does not limit aforesaid way, and in another embodiment, the first single direction ratchet and the second single direction ratchet can be positioned at the same side of wheel rim.
Fig. 4 be the utility model one preferred embodiment electric auxiliary pedal cycle rear wheel unit the spatial structure section-drawing.Please refer to Fig. 4, in this preferred embodiment, the electric motor groups 135 of electric auxiliary pedal cycle 100 comprises a plurality of coil 135a and a plurality of magnet 135b, coil 135a is arranged on the one first circumference C1, magnet 135b is arranged on the one second circumference C2, the first circumference C1 and the second circumference C2 are concentric circles, and the radius of the first circumference C1 is greater than the radius of the second circumference C2.
Fig. 5 is the spatial structure section-drawing of the first ratchet of the electric auxiliary pedal cycle of the utility model one preferred embodiment.Fig. 6 is the section of structure of the second ratchet of the electric auxiliary pedal cycle of the utility model one preferred embodiment.For the start principle of hind axle 131, the first single direction ratchet 132, the second single direction ratchet 133 and wheel rim 136 is described, please refer to Fig. 5 and Fig. 6.
In Fig. 5, the external toroidal ring 132a of the first single direction ratchet 132 links chain drum group 134, and interior ring 132b links hind axle 131.Ratchet in the first single direction ratchet 132 and roller seating space structure be designed to make the external toroidal ring 132a of the first single direction ratchet 132 only can drive in the direction of conter clockwise in ring 132b, and the external toroidal ring 132a of the first single direction ratchet 132 only can be rotated with respect to interior ring 132b in the clws direction.Therefore, the first single direction ratchet 132 only can drive hind axle 131 and wheel rim 136 in the direction of conter clockwise, but the external toroidal ring 132a of the first single direction ratchet 132 only can rotate in the clws direction with respect to hind axle 131.
On the other hand, in Fig. 6, the external toroidal ring 133a of the second single direction ratchet 133 links electric motor groups 135, and interior ring 133b links hind axle 131.The external toroidal ring 133a that ratchet in the second single direction ratchet 133 and roller seating space structure are designed to make the second single direction ratchet 133 only can be in the clws direction drives ring 133b, and the external toroidal ring 133a of the second single direction ratchet 133 only can be rotated with respect to interior ring 133b in the direction of conter clockwise.Therefore, the second single direction ratchet 133 only can drive hind axle 131 and wheel rim 136 in the clws direction, but the external toroidal ring 133a of the second single direction ratchet 133 only can rotate in the direction of conter clockwise with respect to hind axle 131.
When the user steps on interior ring 132b, the hind axle 131 of external toroidal ring 132a that mode sequentially drives chain drum group 134, the first single direction ratchet 132 in the counterclockwise direction, the first single direction ratchet 132 with pin, because the external toroidal ring 133a of the second single direction ratchet 133 only can rotate in the direction of conter clockwise with respect to hind axle 131, so the part of electric motor groups 135 can not driven thereupon.
On the contrary, when the user utilizes electric motor groups 135 sequentially to drive in the clockwise direction interior ring 133b, the hind axle 131 of external toroidal ring 133a, second single direction ratchet 133 of the second single direction ratchet 133, because the external toroidal ring 132a of the first single direction ratchet 132 only can rotate in the clws direction with respect to hind axle 131, so chain drum group 134 can not driven thereupon.
In other words, electric motor groups 135 can independently operate separately with chain drum group 134, and can not interfere with each other.
In sum, electric auxiliary pedal cycle of the present utility model has following advantages at least:
One, in the electric auxiliary pedal cycle that the utility model proposes, when the chain drum group drove hind axle by the first single direction ratchet, the part of electric motor groups can not driven thereupon.Therefore, the user need not expend larger strength when trampling bicycle.
Two, be positioned at the structure in the coil outside compared to the magnet of existing electro-motor, in the electric auxiliary pedal cycle that the utility model proposes, the magnet of electric motor groups group is positioned at the inboard of coil.By the suction of magnet, can make electric motor groups be easier to be assembled on the second ratchet.
Although the utility model discloses as above with preferred embodiment; so it is not to limit the utility model; anyly have the knack of this skill person; within not breaking away from spirit and scope of the present utility model; when doing a little change and retouching, therefore protection domain of the present utility model is as the criterion when looking accompanying the claim person of defining.
