New description: [New technical field] The creation of the "transformation of the transmission device" relates to an electric bicycle power transmission device, which specifically refers to a structure improvement device equipped with a feedthrough type electric unit and a reduction unit. '[Previous technology] In 2006, the US subprime mortgage crisis triggered a financial crisis, which led to the collapse of the financial institution known as Lehman Brothers, which collapsed in September 2008. The financial tsunami swept the world. & A wave of financial tsunami has a wide range of influences, and the international oil price has soared, and the domestic economic climate has been greatly affected. Although oil prices have stabilized, people have begun to pay attention to the problem that petroleum energy will eventually be exhausted. In order to reduce expenses, various electric vehicles and human transportation vehicles are sold well. Among them, the bicycle is not only cheap, it does not need to pay for oil and can achieve exercise and fitness effects, and is the first choice for short-distance travel. However, the human bicycle is suitable for short-distance travel and leisure sports, but it is not suitable for short-distance movement with distance. In order to solve this problem, the manufacturer has developed an electric bicycle with an electric motor. When the ride is tired, the electric mode can be turned on, which greatly increases the range of movement of the bicycle. However, the electric motor and the speed reduction mechanism used in the electric bicycle are designed by other mechanical tools. The electric motor and the speed reduction mechanism are not only required to have a large arrangement space, but also have a limited position. The bicycle is equipped with the most common position of the electric motor and the speed reduction mechanism, and is placed on the rear axle and the rear shelf, causing the center of gravity and the rearward riding to be unstable 3 M395636. In addition, the eccentric speed reduction mechanism can be used for a long time, that is, the gear is collapsed and ground, and at the same time, the torsion force that can be received by the space can be quite limited, and the problem of damage such as damage.遂 以 以 研 , , , , , 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研 研, electric motor and speed reduction mechanism:" Its main purpose is to reduce the configuration space and balance the front and rear center of gravity of the vehicle.

Then, the foot pedal is combined with the second gear to connect the second ratchet. The power shaft, the wheel has a one-way transmission characteristic, and the gear plate can rotate the rear wheel to advance the bicycle. The chain drives the rear gear. Through the above technical means, the electric single unit transmits power to the first ratcheting power shaft, and through the reduction, when the wheels rotate, the bicycle is advanced by the first: ratchet gear: On the contrary, the foot pedal drives the shaft, and ::: belt: the step of the pedal. At this time, the ratchet is... By the above structure, the electric unit and the pedal can be independently transported H395636, and there is no negative interference. Because the output shaft of the electric unit's output end saponin and the flat shaft end of the deceleration flat 97 are hollow rods, it is a step-through type of thread-piercing machine.

[Embodiment] The structure of the project is better. The design of the case is as follows: "The details of the functions that can be produced are as follows: The structure of the transmission is changed" For the first time, please refer to the first and second figures. In this case, the "transmission structure improvement" includes the vehicle body power mechanism 2 and the electricity storage unit ^ 3, wherein the lower end of the vehicle body 1 is provided with a ring sleeve 1 The 2 series is equipped with a Fen " to fix it, and the power storage unit 3 is fixed at the appropriate position of the rut: There is a circuit connected to the power mechanism 2.

As shown in the figure, there is a stator portion 241 and a rotor portion 242. The rotor portion 242 extends a hollow shaft of the power shaft 243. The motor unit 24 is disposed on the rotating shaft 21 5 M395636 by the power shaft 243, and the stator portion 241 is oriented at the end. The side cover 23 is further provided with an inductive element 244 on the outer edge surface of the stator portion 241, which can detect the sensing piece 231. The electric unit 24 has a circuit connecting the electric storage unit 3. The deceleration unit 25' is referred to the sixth and seventh figures. As shown in the figure, the housing 251 is disposed on the power shaft 243. The plurality of medium gears 252 are disposed around the power shaft 243 and can be interlocked, and then the positioning plate 253 is fixed to the position of the fixed gear 252. The gear W is coupled to the power shaft 243 ′ on the side of the gear 254 with the inner ring teeth 2541 in the same direction, and the other side is extended with the output material 255; finally, the gear set is enclosed in the casing (5) by a = 256 However, the cover 256 has an opening for the output end shaft 255 to pass through. The gear I 26 is threaded to the shaft. 21 has a accommodating space 261 (as shown in the fourth figure). The first-ratchet 27 is placed in the accommodating space by the claw portion 271 and the crotch portion m of the shaft 21; 4' and the claw portion 271 Combined with the output end shaft 255, the crotch portion 272 and the power of the god single steering. The inner wall of the 1261 is combined with the 'for the transmission shaft 2^the second wheel 28' consisting of the claw portion 281 and the engine portion 282, which is placed into the glazing The inner side wall is combined with the inner side wall, and the second side is 261, and the engine part and the accommodating space 261 are used for transmitting the single steering dynamic coupling ring 29, the force end and the second spine 28 < The annular connecting block of the rotating shaft 21, one of the claws 28 is coupled, the other end is coupled to the pedal to rotate with the shaft 243, and the electric power of the electric storage unit 3 is driven by the output end two: 243. The power is output to the first ratchet 27 and drives the M395636 26'. At this time, the second ratchet 28 does not drive the pedal 22 and the rotating shaft 21. Instead, the foot pedal 22 drives the rotating shaft 21 and the coupling ring 29, and the second ratchet 28 rotates the gear plate. 26; at this time, the first ratchet 27 does not affect the output end shaft 255. With the above structure, the pedal 22 or the electric single can be arbitrarily selected. As the power source, the element 24 operates independently of each other without negative interference. The sensing element 231 can be detected by the sensing element 244, thereby measuring
