    TRANSMISSION DEVICE
    BACKGROUND OF THE INVENTION 1. Field of the Invention
    The present invention relates to a transmission device of a power-driven bike, and more particularly to a power transmission device having a power-driven unit and a deceleration unit which are coaxially disposed.
    2 . Description of the Prior Art
    People have considered the problem of energy resources . In order to decrease the expenditure on oil, power-driven or manpower vehicles are in a great demand. In particular, a bike is not expensive and can provide an exercise effect. Recently, riding a bike has been a popular exercise.
    A manpower bicycle is adapter for a short distance or leisure exercise, not for a long distance. Therefore, there is a power-driven bike having an electric motor on the market. When the rider is tired, he/she can start the power-driven mode, so that the bike can be used for a long distance.
    However, the power-driven motor and the deceleration mechanism of the power-driven bike use the design of other machines. The power-driven motor and the deceleration mechanism are disposed eccentrically, which needs more configuration space and limits the installation position. In general, the power-driven motor and the deceleration mechanism are located between the shaft of the rear wheel and the rear support. In this way, the bike cannot keep its balance, and the power-driven motor and the deceleration mechanism occupy most of the space. Besides, the bearing torsion of the eccentric deceleration mechanism is limited. After a period of time, the gears suffer a lot of wear and tear, resulting in malfunction.
    Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to improve the aforesaid problems of the conventional power-driven bike and to develop a perfect and practical transmission device.
    SUMMARY OF THE INVENTION
    The primary object of the present invention is to provide an electric motor and a deceleration mechanism disposed on a rotating shaft connected with pedal levers, which decreases the configuration space and keeps the bike's balance.
    In order to achieve the aforesaid object, there is provided a transmission device comprising a power mechanism disposed on a shaft which is located between two pedal levers of a bike. The power mechanism provides a manual power source or an electric power source to drive the bike.
    Through the aforesaid technical means, the power-driven unit drives the power axle and transmits the power to the first ratchet through the deceleration unit to link the gear wheel for the bike to advance. When the gear wheel is turned, the second ratchet won't drive the rotating shaft of the pedal levers . On the contrary, when the pedal levers are trod to drive the rotating shaft and link the second ratchet to turn the gear wheel, the first ratchet won't drive the deceleration unit and the power-driven unit.
    Thereby, the power-driven unit and the pedal levers are separately operated, without interfering with each other. Both the power axle of the power-driven unit and the output axle of the deceleration unit are hollow rods. The rotating shaft of the pedal levers is direct inserted through the power-driven unit and the deceleration unit. This coaxial configuration needs less space. The power-driven unit and the deceleration unit are direct disposed on the rotating shaft of the pedal levers to increase more space for use and keep the bike's balance.

    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
    Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings .
    As shown in Fig. 1 and Fig. 2, the transmission device of the present invention comprises a frame 1, a power mechanism 2, and an energy-saving unit 3. A lower end of the frame 1 is provided with a sleeve 11. The power mechanism 2 is mounted in sleeve 11. The energy-saving unit 3 is secured to the frame 1 and electrically connected with the power mechanism 2.
    As shown in Fig. 3 and Fig. 4, the power mechanism 2 comprises a rotating shaft 21, two pedal levers 22, a side lid 23, a power-driven unit 24, a deceleration unit 25, a gear wheel 26, a first ratchet 27, a second ratchet 28, and a connection ring 29 .
    The rotating shaft 21 is a cylindrical rod.
    Each pedal lever 22 has one end connected to a distal end of the rotating shaft 21 and another end connected to a pedal. Two ends of the rotating shaft 21 are connected with the two pedal levers 22, respectively.
    The side lid 23 is a circular plate inserted on the rotating shaft 21. An outer end of the side lid 23 is attached to the pedal lever 22, and an inner side of the side lid 23 is provided with a plurality of sensor plates 231 as shown in Fig. 4.
    The power-driven unit 24 , as shown in Fig. 3 and Fig. 5, comprises a stator 241 and a rotor 242. The rotor 242 comprises a hollow power axle 243 extending out of the rotor 242. The rotating shaft 21 is inserted through the power axle 243 of the power-driven unit 24. One end of the stator 241 faces the side lid 23. An outer surface of the stator 241 is provided with a sensor member 244 to detect the sensor plates 231. The power-driven unit 24 has a circuit connected with the energy-saving unit 3.
    The deceleration unit 25, referring to Fig. 6 and Fig. 7, comprises a casing 251 inserted on the power axle 243 . A plurality of planetary gears 252 are provided in the casing 251 and located around the power axle 243 to mesh with the power axle 243. The planetary gears 252 penetrate through a positioning board 253 to be secured thereon. The power axle 243 is further inserted through a teeth ring 254 . One side of the teeth ring 254 has annular inner teeth 2541 to mesh with the planetary gears 252. Another side of the teeth ring 254 has an output axle 255. A cover 256 is adapted to cover the gears in the casing 251. The cover 256 has a hole for the output axle 255 to pass therethrough.
    The gear wheel 26 is inserted on the rotating shaft 21 and has a chamber 261 at a central portion thereof, as shown in Fig. 4 .
    The first ratchet 27 is composed of a detent part 271 and an engaging part 272 . The first ratchet 27 is inserted on the rotating shaft 21 and located in the chamber 261. The detent part 271 engages with the output axle 255, and the engaging portion 272 engages with an inner wall of the chamber 261 to transmit one-way rotating power.
    The second ratchet 28 is composed of a detent part 281 and an engaging part 282. The second ratchet 28 is inserted on the rotating shaft 21 and located in the chamber 261. The engaging portion 282 engages with the inner wall of the chamber 261 to transmit one-way rotating power.
    The connection ring 2 9 is an annular connecting block inserted on the rotating shaft 21. The connection ring 29 has one end connected to the detent part 281 of the second ratchet 28 and another end connected to the pedal lever 22.
    The power-driven unit 24 uses the electric power from the energy-saving unit 3 to drive the power axle 243. The power axle 243 drives the gears in the deceleration unit 25, and the output axle 255 outputs power to the first ratchet 27 to turn the gear wheel 26. At this time, the second ratchet 28 won't drive the pedal levers 22 and the rotating shaft 21. On the contrary, when the pedal levers 22 are trod to drive the rotating shaft 21 and the connection ring 29, the second ratchet 28 will turn the gear wheel 26 . At this time, the first ratchet 27 won't drive the output axle 255.
    Accordingly, the user can choose the pedal levers 22 or the power-driven unit 24 as the power source. They both are operated separately, without interfering with each other. Preferably, the sensor member 244 detects the sensor plates 231 to measure the rotational speed of the pedal levers 22. Through a program, the power-driven unit 24 can be activated automatically, for example, when the rotational speed of the pedal levers 22 is slow, the power-driven unit 24 will be activated as the power source.
    The rotating shaft 21 is direct inserted through the power-driven unit 24 and the deceleration unit 25. This coaxial configuration needs less space and can keep the bike's balance. Besides, the deceleration unit 25 uses the plurality of planetary gears 252 to transmit the power, dispensing the strong torsion from the power axle 243 so as to increase the upper limit value of bearing the torsion. The present invention provides a steady structure without noise.
    To sum up, the present invention can reduce the configuration space, keep the bike's balance, increase the space to be used, enhance durability and is quiet.
    Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements maybe made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims .
