Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and examples.

Referring to fig. 4 and 5, an embodiment of the front bicycle driving apparatus of the present invention is provided in a front bicycle 9, wherein the front bicycle 9 includes a front wheel axle 91 extending along an axis L, a front wheel 92 directly linked with the front wheel axle 91 and being incapable of steering, and a rear wheel (not shown) being operable to steer.

The front pedaling bicycle driving device comprises a supporting rod 2, an extension rod 3, a fixing unit 4 and a pedal unit 5.

The support rod 2 includes a sleeve portion 21 for being sleeved on the front axle 91 along the axis L, a support portion 22 extending from the sleeve portion 21 in a direction perpendicular to the axis L, and a fixing portion 23 connected to a side of the support portion 22 opposite to the sleeve portion 21.

The sleeve portion 21 has an operation section 211 connected to the support portion 22, and a through section 213 connected to the operation section 211 and extending toward the front axle 91, wherein the operation section 211 has an operation hole 212, and the through section 213 has a special-shaped hole 214 communicating with the operation hole 212 and used for the front axle 91 to pass through. In this embodiment, the operation hole 212 is used for installing a screw 93 to fix the front axle 91, and the shaped hole 214 is square.

The extension rod 3 extends along a direction perpendicular to the axis L, and has a central portion 31 sleeved on the sleeve portion 21, a connecting section 32 connected to a side of the central portion 31 corresponding to the support rod 2, and a stressed section 33 connected to a side of the central portion 31 opposite to the connecting section 32.

The central portion 31 has a through hole 311 penetrating along the axis L, and the through section 213 of the sleeve portion 21 is inserted into and fixed to the through hole 311.

The fixing unit 4 connects the fixing portion 23 and the connecting section 32. In this embodiment, the fixing unit 4 is in the form of a screw and a nut to connect the fixing portion 23 and the connecting section 32.

The pedal unit 5 includes a shaft 51 disposed on a side of the force-receiving section 33 away from the central portion 31, and a pedal 52 rotatably disposed on the shaft 51.

When the bicycle is used, a user only needs to step on the pedal 52, and the shaft lever 51, the extension rod 3 and the support rod 2 can be driven to rotate around the axis L, so that the front wheel shaft 91 is driven to drive the front wheel 92 to rotate and move forwards. It should be noted that, in normal use, another front pedaling bicycle driving device (not shown) is disposed on the other side of the front wheel 92, and the front wheel 92 is driven to rotate in a manner of pedaling alternately, but for simplicity of description, only one front pedaling bicycle driving device is described in the present embodiment.

Referring to fig. 4, 5 and 6, when the pedal 52 is rotated to the highest point, the user's obliquely stepping on the pedal 52 generates a downward force F1 and an outward force F2 along the extension direction of the axis L on the force-bearing section 33 of the extension rod 3, and at this time, the extension rod 3 uses the central portion 31 as a fulcrum and the connecting section 32 on the other side generates an inward force F3 opposite to the outward force F2.

At this time, since the support rod 2 is fixed to the central portion 31 and the connecting link 32, most of the inward acting force F3 is restricted and cancelled, and the outward acting force F2 is also greatly reduced, so that the outward acting force F2 and the inward acting force F3 are both greatly reduced, and thus the outward yawing acting force of the front wheel 92 is also greatly reduced, and therefore, the front wheel 92 can be stably moved forward.

As described above, by providing the support bar 2 and the extension bar 3, the outward acting force F2 and the inward acting force F3 can be reduced when the pedal 52 is depressed, and the front wheel 92 of the front pedal bicycle 9 can be reduced from being deflected, so that the object of the present invention can be achieved.
