New Description·· 【New Technology Fields】 This creation is related to an electric bicycle. More specifically, it refers to the improvement of the driving structure of an electric bicycle. [Prior Art] According to the electric bicycle driving structure, such as the bicycle of the publication No. 5 6 6 3 9 3 _ Patent, there is a frame with a loosely extending shaft tube on the bottom side of the frame. A crankshaft is pivoted, and a crank is arranged at each end of the crankshaft, and a driving device composed of a gear, a driving motor, a positioning bracket and a large sprocket is arranged on the bottom side of the frame, and the gear and the crankshaft are arranged on the crankshaft and the crankshaft. A one-way bearing is arranged between the driving shaft of the driving motor to directly drive the large sprocket to drive the bicycle to advance, although the driving shaft of the driving motor can be driven by the gear, the large sprocket, etc. through the design of the one-way bearing. At the same time of the advancement, the crank rotation is not driven, but since the large sprocket and the gear train are coupled to each other, and the drive shaft of the drive motor and the gear train are kept in meshing shape, therefore, when the rider pedals the crank with human power When the large key wheel rotates to advance the bicycle, the gear that is integrally coupled to the large sprocket and the drive shaft that holds the meshing drive motor will also be driven together. As a result, the part of the pedaling force applied to the crank will be lost due to the rotational resistance of the drive shaft, and the pedaling efficiency will be reduced. It is also more laborious to ride on the pedal. In addition, the drive shaft of the drive motor is stepped on by the human. When driven by unnecessary driving, it will also accelerate the driving of the motor-rotating shaft related structure and shorten the service life; and, as in the bicycle driving structure of the Patent No. 574999 patent, although the human pedaling is separated from the electric drive independently, However, the structure of the M290853=$dynamic drive needs to be driven by the deceleration of the motor reducer to drive the drive shaft, which not only increases the cost, but also drives the rear wheel to cause insufficient torque due to the transmission of the reduction gear. [New content] This is a kind of improvement of the driving structure of electric bicycles. It is mainly based on the bicycle structure of human-like pedaling. In addition::: The shaft is threaded on the other side of the gear plate of the human pedaling drive. On the side 2 of the pivot-toothed disc: "The knife is provided with a second toothed disc and a third toothed disc is attached to the two-side port clamp" and the frame is driven by its 6 proximal shaft S. Electric: The coin says "1 zone between the moving gear and the second toothed disc - the second chain, ::: The output power of the output is indirectly transmitted to the third toothed disc, and at the same time, the flower valley is installed with - Two flywheels, and after the second flight, there are H strips in U, and (four) move the rear wheel assembly and then turn the wheel into the 'electrical and pedaling functions. The drive structure provided by the move is due to the human Stepping on the drive is free to use - drive (9) wants to " & again" will use the surname 槿 early l ag drive operation, and is not convenient for the other - drive and can reduce the ignorance of the pedaling power, so that the pedaling is more effectiveness. · [Embodiment] First, please refer to the first article, I have a wheel assembly (not in the picture, M290853 does not), the rear wheel assembly 20 and a pad assembly 3 〇, at the same time, the 1 〇 shaft tube 1 1 The cranking shaft 2 is provided with a crank shaft 2, and the crank shaft 1 2 is connected with a crank i 3 with a pedal 1 3 1 , so that the pedal 1 3 of the crank 13 is subjected to the pedaling force. The moxibustion can drive the first tooth M1 4 on the 2-end of the crank to rotate, and then drive the rear wheel assembly 2 to the flower hub 2 through the first chain 15 disposed on the first tooth 4.

Secondly, the electric motor 43 of the present electric bicycle must also provide the required power from the pool 49. The battery of the present embodiment is installed on the upper fork 18 after the vehicle 10, because the battery 4 9 Providing electric motor 43 power is not a feature of this creation structure, so it is not repeated. In order to understand the structure characteristics of this creation, the use of technical means and the expected effect, we will describe the use of this creation, I believe that this can be more in-depth and specific to this creation, as described below. · Please refer to the first and second pictures again. The electric bicycle of this creation has the traditional Q step function and electric drive function, which can be used by the rider according to individual needs. Because the manpower is driven by the same method as the conventional one. Therefore, no more details are mentioned. As for the rider, when the electric drive mode is selected, the control (4) motor 43 is operated, so that the force can be transmitted through the drive gear 4 3 3 via the second chain 4 5 . The two-toothed disc "rotates and produces the effect of deceleration and increased torque. After that, it is connected to the toothed disc holder 41 of the M290853 knot and then through the third chain 4 8: moving: two 6 synchronous rotation, finally, two flywheels 4 7 The ri·”TΓΓ flywheel 4 7 rotation' is connected to the first forward action, and the second and its rear wheel 2 3 are driven to drive to achieve the electric drive function. The creation snow can also be applied to the two-seat car of the seat = the driving structure of the car 牟]n, the structure of each car, that is, the car of the two cars and the at least two components of the car At least two manpower stepping on the drive, the mouth, and the creation of the electric motor 4 3, the second He You / R eleven 4 4 and other electric drive structure II, the younger two-toothed disc configuration rear wheel P ^ .. 纟Sigh on the back side of the stepping drive knot "Man wheel 2 3" hunting to provide the electric drive function of the synergy car. The description of the ^ is not because 'this creation is in the general manpower stepping on the drive port, and the independent wire-electric drive structure, especially in the electric drive structure, one or two blood 1 ^ inch (7) smart electric fixed; ^ Ί The two 4, 48 series are integrally connected to the sprocket wheel: 1, and the sprocket holder 4 1 is pivoted to the frame 2 of the frame, and has no connection with the crankshaft 12, *, can produce a drive structure completely independent of the human treading part, 俾 7 % passenger phase - drive structure (4) operation, will not be interfered by the other - drive structure, so the overall operation is quite convenient and smooth, Moreover, it is possible to avoid the fact that the conventional pedaling power is damaged by the rotational resistance of the driving motor 4 3, making the pedaling more labor-saving and more efficient. In addition, the diameter and the number of teeth of the second toothed disc 4 4 are significantly larger than the number of teeth. The electric horse 4^ drive gear 4 3 3 is designed to generate a deceleration effect, and to drive the torque of the electric motor 4 3 and reduce the power consumption. At the same time, it also makes the 4 electric horse $ 4 3 #With other speed reduction mechanisms, It can be achieved and the reduction gear 10 M290853 effect. In summary, this creation has its excellent progress and practicality in similar products. At the same time, it has investigated the technical information about such structures at home and abroad. The same structure has not been found in the literature. This creation has already prepared a new type of patent, and applied for it according to law. The person who is fascinated by the syllabus is only one of the preferred and feasible examples of this creation. The application of this syllabus and the changes in the scope of the patent specification should be included in the scope of this creation.
