Description of the Invention: [Technical Field] The present invention relates to an electric bicycle driving mechanism (4), and more particularly to a bicycle driving mechanism having both electric and pedal driving modes, and the cooker has a simple structure and a reduced structure. Take up space, reduce manufacturing costs, make the car body weight 1 balance and reduce the weight of the car, and can make full use of the transmission function 'to save power and improve torque and increase the climbing power and other features and functions. [Prior Art] According to the convenience of the bicycle and the physical burden of the bicycle rider, the electric bicycles that replaced the manpower with electric motors have been popular in recent years. The motor drive design of the electric bicycle can be divided into the following four categories: The first type of motor is set outside the front or rear wheel, and the motor shaft is parallel to the wheel axis after driving. , leather The first type: the motor is set on the bracket behind the rear or front wheel and the shaft and the driven wheel are straight. ~ 2. The motor is directly coupled to the front or rear wheel and directly into the mandrel of the wheel. t ϋ 4 i ' Features the main system of the motor with the front or rear wheel turning 5 1308892. The fourth category: the motor is perpendicular to the pedal drive shaft and drives the front sprocket via the transmission element. So far, the driving mechanisms of most electric bicycles on the market are mostly the first, second and third types of designs mentioned above, and the fourth category is a small number. The above-mentioned first type of transmission mode is as shown in the new patent No. 522964 of the first figure. The motor A1 of the conventional electric bicycle is set outside the rear wheel, so that the motor shaft is arranged in parallel with the wheel shaft after being driven. And the sprocket A3 fixed to the rear wheel is driven by the transmission element A2. The second type of transmission is as shown in the second figure. The motor B1 of the conventional electric bicycle is assembled on the rear frame B2, and the motor shaft is vertically disposed after being driven. The transmission element drives the sprocket B3 fixed to the rear wheel. • The third type of transmission is shown in the new figure of M259755 in the third figure and the new invention in the fourth figure. No. 467091, please refer to the third figure. The motor C1 of the electric bicycle is directly combined with the front wheel C2. Therefore, the axis of the motor is the axis of the wheel, and the front wheel is driven by the connection of the motor and the transmission element; for the fourth embodiment, the motor D1 of the conventional electric bicycle is directly coupled with the rear wheel D2. The motor D1 is coupled to the transmission element to drive the rear wheel D2 to rotate. 6 1308892 For the fourth type of transmission, please refer to the new patent of Bulletin No. 192351 of the fifth figure and No. 519087 of the sixth figure. As shown in the fifth figure, the motor E1 of the electric bicycle is transmitted through the steering transmission component E4. And the chain E5 is coupled to the front sprocket E2. The motor El is disposed perpendicularly to the pedal drive shaft E3. The main function is to drive the key wheel E2 by using the steering transmission element E4 parallel to the front sprocket E2. The driving of the rear wheel is performed; as shown in the sixth figure, the motor F1 of the conventional electric bicycle is coupled with the front sprocket F2, and the motor F1 is vertically disposed with the pedal driving shaft F3, and is driven by a group. The device F5 (shown in Figure 7) drives the front sprocket F2' to cause the front sprocket F2 to rotate with the chain F4 and the rear wheel to rotate. However, the aforementioned four types of systems have the following disadvantages: 1. The transmission modes of the first, second and third types of systems are designed to directly drive the motor (such as Al, Bl, Dl, E1) to the front wheel or the rear. The wheel is driven without the transmission function. As a whole, in addition to the power and strength of the gearbox, the climbing force is also small. 2, the first type of transmission, as shown in the first figure, because the motor μ parallel device is outside the rear wheel, and the radius of the rear wheel is not small, so the longer chain A4 (or belt) is required, the relative cost will be Higher and easier to fall off. 3, the second type of transmission, as shown in the second figure, the motor B1 must be 1308892 shank plus the new record as the transmission component to change the transmission direction, "wheel axle flat (four) move. Because * wheel set __ In addition to the cost of manufacturing, the mechanical components are considered to be suitable for lubrication. In addition, the motor B1 of this type of transmission is recorded in the rear frame B2, and the overall weight of the electric bicycle will be severe. The left and right are unbalanced, and the right motor is installed outside the rear wheel. It will also be easy to install a pedal that can be used by the carrier because it occupies a considerable space. 4. The third _ movement mode is like the third ride. It shows that the motor is wrapped inside the mandrel of the front rim' and the motor system will rotate with the front wheel ^; and the fourth system shows that the motor D1 _ is set on the rear axle of the rear wheel and the main system of the motor Will rotate with the rear wheel D2. The motor used in this type of transmission is not a general specification, but needs special order, and its manufacturing cost is high'. When the dynamic balance is not done, the car will travel when it travels.
