    Electric bicycle with load-sensitive variable discharge drive
    BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle, and in particular, an electric bicycle having a load-sensitive automatic transmission that can selectively change the charging and output according to the increase or decrease of the load acting on the bicycle by contacting the tires of the front wheel or the rear wheel of the bicycle. It is about.
    Conventional electric bicycles generally have a power or manual adjustment by means of electronic devices (including a torque sensor for recognizing the pedaling force), so there is a problem in discomfort in driving and in malfunction or shock in cold or rainy weather.
    In addition, the existing electric bicycle generally adopts a driving method using a very large gear ratio, and when driving downhill or when a load below a certain level is applied to the bicycle, the axial energy generated by the driving unit itself effectively prevents the kinetic energy of the power. There was a problem that could not be charged.
    In addition, in the conventional electric bicycle configured as described above, a plurality of gears and belts are provided by adopting a driving method using a large gear ratio.
    The loss was relatively increased, and there was a difficulty in attaching the existing general bicycle due to the difficulty in attachment due to the increase in volume and weight.
    In addition, despite the advantage of quick driving response and less energy loss compared to rear wheel drive, it is not easy to attach due to the volume and weight. Although the steering convenience is improved compared to the front wheel drive, there is a problem such that the instantaneous oscillation ability is lowered by adopting a driving method using a large gear ratio.
    Therefore, the present invention has been made to solve the above problems, and an object of the present invention is to reduce the power consumption by replacing the unreasonable point of output adjustment by manual or electronic device with mechanical operation according to the increase or decrease of the load acting on the bicycle. Another object of the present invention is to provide an electric bicycle equipped with a load-sensitive variable discharge driving device that can selectively change the charging and output.

It is characterized in that the type drive device is provided in a predetermined portion of the electric bicycle body.
    Hereinafter, a detailed description of a preferred embodiment of the electric bicycle according to the present invention with reference to the accompanying drawings.
    Figure 1a is a schematic diagram of an electric bicycle with a drive device according to the invention,
    Figure 1b is a partial detailed view showing the position of the drive device and the application of the contact in the charging mode,
    FIG. 2 is a view of the planar state in FIG. 1A to illustrate the structure of the drive means of the present invention.
    Referring to the drawings, the electric bicycle of the present invention is provided with a driving device for driving the bicycle in the predetermined position of the base housing 65 of the bicycle, the drive device 90 is a friction gear in contact with the bicycle wheel (91) (5), a motor 40 connected to the friction gear 5 to generate or transmit power, and a power transmission member 10 for transmitting power between the friction gear 5 and the motor 40; 15 and 20, a transmission contact terminal 31 serving as a connection point for transmitting the current generated in the charging mode to the power supply unit 50, and a relay 56 for selecting the current received from the contact terminal 31; The amplifier 56 is largely configured to amplify the current in accordance with the strength of the current selected from the relay 56.
    In particular, the power transmission member (10, 15, 20) is to transfer power between the friction gear 5 and the motor 40, the friction gear drive gear connected to the friction gear drive shaft 14 ( 15 and the belt 20 which transmits power to the pinion gear 10 connected to the motor 40 in contact with the friction gear driving gear 15.
    In addition, the drive unit 90 of the present invention is formed with a drive unit housing 30 for receiving the motor 40, the power transmission member (10, 15, 20), and the predetermined position of the center of the drive unit housing 30 A driving device rotating shaft 81 is installed in the driving device, and the driving device rotating shaft 81 is fitted into the driving device rotating shaft moving groove 94 of the front and rear base housings 65a and 65b, and the driving device rotating shaft moving groove ( 94, the movement limit region in the up-and-down direction of the drive housing 30 is determined.
    Accordingly, the drive housing 30 is the base 60 and the interaction between the drive rotation shaft 81 and the drive rotation shaft moving groove 94 of the front and rear base housings 65a and 65b coupled to a predetermined position of the center thereof. Friction of the drive housing 30 through the interaction of the rack 80 formed similarly to the curvature of the bicycle wheel 91 and the drive gear moving pinion gear 85 formed on the drive 90 at a predetermined portion of The tire of the gear 5 and the bicycle wheel 91 is kept in contact with a certain pressure state.
    On the other hand, the power (signal) transmitted from the drive housing 30 is transmitted to the base 60 to apply the supply and charging of power, the transmission means is a transmission contact installed on the drive housing 30 And a transmission contact rod 32 fixed on the terminal 31 and the base 60.
    Here, the shape of the transmission contact rod 32 of the transmission contact terminal 31 may be variously modified according to the installation position and the operating state of the drive device.
    In particular, Figures 1a and 2b is shown the position and contact application state of the drive device in the charging mode of the drive device according to the present invention.
    As shown, the kinetic energy of the free energy transmitted from the tire 91 of the bicycle to the friction gear 5 which is in contact with the tire 91 of the bicycle during downhill driving or manpower driving, the drive housing 30 is a certain angle. Rotation is led to charging mode.
    At this time, the transmission contact terminal 31 and the transmission contact rod 32 of the driving device housing 30 operate the generation system as an automatic contact. That is, as shown in FIG. 1B, when the bicycle is in a downhill driving state, the driving device housing 30 is advanced forward by the rotation of the bicycle wheel, and thus is generated by the rotation of the friction gear 5. In order to charge power of the driving force, the driving device 90 automatically converts to a charging mode state, which is a contact terminal for causing the contact link 35 to be converted into a charging mode among a plurality of contact terminals installed on the transmission. For example, in the present embodiment, the following two contact terminals 31d and 31e are contacted by mechanical motion. In this case, the remaining three contact terminals 31a to 31c automatically contact the contact link 35 to each contact terminal when a load of a predetermined level or more is applied to the bicycle. It can be converted into a state capable of driving.
    That is, while the tire 91 of the bicycle wheel and the friction gear 5 are always maintained at a proper pressure state, when the driving force of the friction gear 5 acts more powerfully, the drive housing 30 is constant so as to charge the power of the margin. The angular rotation is made so that the contact link 35 is in contact with the two contact terminals 31d and 31e enabling the charging mode.
    Here, before and after the base, the upper and lower support elastic springs 70a and 70b are installed in a predetermined portion of the base 60 in the present invention, but the support elastic springs 70a in the front and rear directions and the upper and lower support elastic springs are provided. The front and rear tension adjusting levers are provided at one end of the spring 70b so that the tire 91 and the friction gear 5 of the bicycle wheel are always maintained at an appropriate pressure.
    On the other hand, in order for the drive device 90 of the present invention to mechanically guide the automatic conversion to the charging mode, the base 60 provided before and after, the upper and lower support elastic springs (70a, 70b) and The interaction between the rack 80 provided in the predetermined portion of the base 60 and the drive gear moving pinion gear 85 provided in the drive housing 30 should be smoothly performed.
    The drive device moving pinion gear 85 is provided with a rotation control lever 86 at one end of the drive device moving pinion gear rotation shaft 88 for the control of rotation, so that fine adjustment of the speed and output is possible by a separate operation of the driver. It is configured to be possible.
    Therefore, by adjusting the rotational resistance of the drive gear moving pinion gear 85 to the rotation control lever 86 of the drive gear moving pinion gear rotation shaft 88, when the rotational resistance is large to form a relatively low speed and torque, the rotation When the resistance is low, it is configured to enable relatively high speed and torque.
    At this time, the fixing, installation position and the number of installation of the upper and lower support elastic springs 70a and 70b and the rack 80 and the pinion gear 85 for moving the driving device, before and after they are installed on the base 60 of the driving device. Is illustrative and does not limit the invention.
    In addition, the transmission contact terminals 31a to 31e are divided so as to be automatically shifted according to the magnitude of the power. In the present embodiment, the terminal is divided into five terminals, but may be arbitrarily converted as necessary.
    Accordingly, the electric bicycle of the present invention does not rely on the conventional manual or electronic device when changing the driving mode, that is, the rotational force transmitted from the wheel 91 of the bicycle to the friction gear 5 without the consumption of the electric current according to the operation of the electronic device. On the basis of this, it is possible to switch to the charging and driving mode.
    On the other hand, the shape of the friction gear 5 is formed by giving a predetermined curvature so that effective contact and power transmission with the tire 91 of the bicycle can be made.
    3A and 3B show the position and contact application state of the drive device in the normal driving mode of the electric bicycle according to the present invention.
    Referring to the drawings, during normal driving of the bicycle, since the rotational force applied to the wheel 91 of the bicycle from the friction gear 5 installed in the driving device 90 acts larger than the rotational force of the wheel itself, the drive housing 30 is shown. As shown in FIG. 3B, the contact link 35 is brought into contact with the contact modes 31a to 31c in the non-charged mode state among the plurality of contact terminals as shown in FIG. 3B.
    On the other hand, when changing from the normal driving mode of the bicycle to the uphill driving, since the power transmitted from the friction gear 5 to the bicycle wheel 91 should be increased relatively than the normal driving mode, as shown in Figures 4a and 4b The link 35 comes into contact with the topmost contact mode 31a.
    As described above, the bicycle of the present invention is transferred from the wheel tire 91 of the bicycle and the movement of the drive housing 30 is made differentially according to the magnitude of the weight and load applied to the friction gear 5. The automatic contact between the transmission contact terminal 31 fixed to the drive housing 30 and the transmission contact rod 32 of the base 60 is configured to achieve smooth running.
    In addition, in the electric bicycle according to the present invention, the movement of the drive housing 30 by the upper and lower support elastic springs 70a and 70b installed at a predetermined portion of the main body of the bicycle according to the degree of rotational force of the wheel. The transmission contact terminals 31d and 31e in the charging mode are operated by the rotational force transmitted to the friction gear 5 when the friction gear 5 is in contact with the bicycle wheel tire for the automatic generation system operation. Accordingly, in the charging mode, the drive device housing 30 moves in the front direction of the bicycle, and moves in the rear direction of the bicycle according to the degree of rotation of the wheel during the driving of the bicycle, and the strength and weakness of the current supplied according to the movement degree is reduced. I can regulate it.
    Meanwhile, the friction gear 5 of the driving device of the present invention may be attached to the front wheel or the rear wheel of the wheel 91 of the bicycle.
    5A and 5B show the shape of the front and rear base housings according to the present invention.
    The drive device rotation shaft moving groove 94 of the front and rear base housing (65a, 65b) is fitted to the drive device rotation shaft 81 installed at a predetermined position of the center of the drive housing 30, the drive device rotation shaft moving groove The movement limit region in the up-and-down direction of the drive housing 30 is determined according to the shape of 94.
    In addition, the present invention is configured to detachable front and rear base housing (65a, 65b) in a predetermined portion of the base 60 so that it can be easily maintained only by detaching the safety cover when disassembly due to mechanical failure that may occur later. do.
    As described above, the electric bicycle equipped with the load-sensitive drive device of the present invention can vary the output by the manual or electronic device according to the increase or decrease of the load acting on the bicycle.
