[0089] The concentric shaft drive structure further includes a rear cover 86 and a circuit board 87. The circuit board 87 is disposed inside the housing 81 and is disposed near the rear cover 86. The circuit board 87 is used to electrically connect the battery and the drive motor 82 so that the battery can power the drive motor 82, and the drive motor 82 can drive the driving gear 85 to rotate.

[0090] The rear cover 86 is connected to the end of the housing 81 away from the driving gear 85 by screws, and is used to encapsulate the circuit board 87.

[0091] One end of the housing 81 away from the rear cover 86 is connected to the packaging shell 84 by screws.

[0092] The driving motor 82 includes a rotating base 821 and a driving shaft 822 connected thereto. The driving shaft 822 is located at one end of the rotating base 821 away from the driving motor 82. The driving shaft 822 has a notch along its axial direction to facilitate snap-fitting with the reduction mechanism 84, thereby driving the reduction mechanism 84 to rotate.

[0093] The first bearing 83 comprises a first inner ring 831 and a first outer ring 832 connected in rotation, and the outer wall of the rotating seat 821 is fixedly connected to the first inner ring 831, which can be fixedly connected by welding. The outer wall of the first outer ring 832 is fixedly connected to a part of the speed reduction mechanism 84.

[0094] The speed reduction mechanism 84 comprises a body 841, a first connecting piece 842, a second connecting piece 843, a transmission mechanism 844 and a driven part 845. The first connecting piece 842 is connected to one end of the body 841 facing the driving motor 82 by screwing, and the second connecting piece 843 is connected to the other end of the body 841 away from the driving motor 82 by screwing. The transmission mechanism 844 is connected to the driving shaft 822 and the driven part 845 at the same time. When the driving motor 82 drives the driving shaft 822 to rotate, the driving shaft 822 drives the driven part 845 to rotate through the transmission mechanism 844. The driven part 845 is connected to the driving gear 85, thereby driving the driving gear 85 to rotate.

[0095] The first connecting piece 842 is provided with a first connecting through hole 846, and the hole wall of the first connecting through hole 846 is fixedly connected to the outer wall of the first outer ring 832. The second connecting piece 843 is also connected to the shell 81 by screwing, so that the body 841 and the shell 81 are connected together. During the working process of the driving motor 82, the body 841 and the shell 81 are both in a state of being fixedly immovable. The driving motor 82 drives the rotating seat 821 and the driving shaft 822 to rotate synchronously, and the rotating seat 821 drives the first inner ring 831 to rotate relative to the first outer ring 832. It can be understood that the driving motor 82 is connected to the speed reduction mechanism 84 through the first bearing 83. Through the additional connection and guiding effect of the first bearing 83, the driving shaft 822 can also maintain a stable connection state with the driven part 845 of the speed reduction mechanism 84 after long-term use, and is not easy to deviate, so as to prolong the service life of the driving motor 82.

[0096] The transmission mechanism 844 is engaged with the body 841 and the driving shaft 822 at the same time. The transmission mechanism 844 is connected to the driven part 845, and the driving shaft 822 can drive the transmission mechanism 844 to rotate, thereby driving the driven part 845 to rotate.

[0097] Reference Figure 14 and Figure 15 The transmission mechanism 844 comprises a plurality of driven gears 847, which are arranged around the central axis of the driven part 845, and each driven gear 847 is rotatably connected to the driven part 845. Specifically, the driven part 845 is provided with a plurality of stand columns 848 around the central axis, and each driven gear 847 is inserted into the corresponding stand column 848, so that the driven gear 847 can rotate on the stand column 848.

[0098] Each driven gear 847 engages both the inner wall of the body 841 and the drive shaft 822. Specifically, the inner wall of the body 841 has a plurality of teeth, and each driven gear 847 engages a tooth. The drive shaft 822 is located between the plurality of driven gears 847, and when the drive motor 82 drives the drive shaft 822 to rotate, the drive shaft 822 drives the plurality of driven gears 847 to rotate simultaneously in one direction by engaging the teeth. Since the body 841 is fixed, the teeth of the inner wall of the body 841 can apply a reaction force to the plurality of driven gears 847, and drive the plurality of driven gears 847 to move in a circular motion around the central axis of the driven member 845. When the plurality of driven gears 847 move in a circular motion, the plurality of driven gears 847 can drive the plurality of columns 848 to move in a circular motion, thereby driving the driven member 845 to rotate.

[0099] The concentric shaft driving structure further comprises a second one-way bearing 88, and the driven member 845 is connected to the driving gear 85 through the second one-way bearing 88. When the driven member 845 rotates, the driven member 845 can drive the driving gear 85 to rotate through the second one-way bearing 88.

[0100] Reference Figure 16 The driving gear 85 and the driven gear 70 are both provided with a plurality of helical teeth along the circumferences thereof, and the teeth of the driving gear 85 and the driven gear 70 engage each other. The rotation axis of the driving gear 85 is perpendicular to the rotation axis of the driven gear 70. The driving gear 85 drives the driven gear 70 to rotate by engaging the teeth. The driven gear 70 is connected to the sprocket 62, and thus the sprocket 62 can rotate, and the bicycle can run.

[0101] It should be emphasized that the first one-way bearing 68 and the second one-way bearing 88 in the present application are both conventional components, and the second transmission member 66 is connected to the driven gear 70 through the first one-way bearing 68. When the second transmission member 66 rotates in the forward direction relative to the driven gear 70, the second transmission member 66 can drive the driven gear 70 to rotate through the first one-way bearing 68. When the second transmission member 66 rotates in the reverse direction relative to the driven gear 70, the inner ring and the outer ring of the first one-way bearing 68 rotate relative to each other, and thus the second transmission member 66 cannot drive the driven gear 70 to rotate. The principle of the second one-way bearing 88 is the same as that of the first one-way bearing 68, and thus will not be described in detail.

[0102] When the drive motor 82 drives the driven member 845 to rotate in the forward direction, the driven member 845 can drive the second one-way bearing 88 to rotate, and thus the second one-way bearing 88 drives the driving gear 85 to rotate. When the driven member 845 rotates in the reverse direction, the driven member 845 cannot drive the second one-way bearing 88 to rotate, and thus the bicycle cannot run. In this way, the drive motor 82 can be prevented from being misoperated when it fails.

[0103] When the user pedals the pedals with both feet, the connecting shaft 61 can be driven to rotate forward, the connecting shaft 61 drives the first one-way bearing 68 to rotate forward in turn through the first transmission member 65 and the second transmission member 66, the first one-way bearing 68 drives the driven gear 70 to rotate forward, and then the driven gear 70 drives the chain wheel 62 to rotate forward, so that the bicycle runs. When the user pedals the pedals with both feet to drive the connecting shaft 61 to rotate reversely, the second transmission member 66 cannot drive the first one-way bearing 68 to rotate reversely, but relatively rotates reversely with the first one-way bearing 68, at this time, the driven gear 70 cannot be driven to rotate, and then the chain wheel 62 cannot be driven to rotate.

[0104] The technical features of the above-described embodiments can be combined in any manner. To make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not contradict, they should be considered as falling within the scope of the present disclosure.

[0105] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the patent. It should be pointed out that, for ordinary skilled persons in the art, some modifications, replacements and improvements can be made without departing from the concept of the present application, and these should be covered within the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the claims.
