[Embodiment] FIG. 1 is a schematic diagram of an outdoor riding bicycle according to an embodiment of the present invention. The main body of the bicycle 10 of the present embodiment is the same as that of a general electric bicycle, and the motor is disposed at the center of the rear wheel 114. The motor 112 is integrated with the rear wheel 114, and the stator is fixed to the axle of the rear wheel 114, and the rotor is interlocked with the rear wheel. The gear 106 connected to the pedal 108 is shiftable, and is coupled to the rear wheel 114 by the chain 110. The user steps on the pedal 108 to rotate the gear 106, and drives the chain 110 to rotate the rear wheel 114, thereby rotating the generator 112 to generate electricity. The generated power is regulated by the voltage regulator 118 to provide power to various electronic devices on the bicycle, such as the front LED illumination 104, the rear LED illumination and 116, the LED directional lights 102 and 120, and the mobile phone/PDA. / Satellite navigation / MP3 and other portable devices charging the charging stand 122. 2 is a schematic view of the bicycle 10 of FIG. 1 when it is used as a power generation or fitness device. The bicycle is erected by the fixed brackets 126 and 128 which are commonly attached to the bicycle, and the foot pedal 108 is stepped on to drive the generator 112 to generate electricity. In other embodiments, only the rear wheel 114 can be erected. In the present embodiment, the voltage regulator 118 has no function and the power generated by the generator 112 is changed to the flow module 22. When the generator 112 is connected to the AC mode, the flow generator 22 feeds the power generated by the generator ιΐ2 into the mains; when the motor core is connected to the battery 26, the generator power knob 124 is used to Adjusting the generator u2' while adjusting the output power of the generator is provided by the user stepping on the tread pedal (10), so the power = the function of consuming calories. When the AC module 2=module 20 uses the &&, the charger or the computer to display the second=hand=computer, the power can be turned off by the hand to turn on the J2:= machine or the computer has a control program, the moment Changed by the control program. The control program provides various modes of motion such as brake rotation (such as slope, distance, strength, and the choice of the brakes of the brakes to change the generator's stroke and the same (four) torque according to the user's vehicle, so that the (four) branches are supplied with The pedals, the good ones with multimedia animation simulation r'1, riverside, city...::: knot: can be connected to other people through the network, if the system is going to enter, in the riding power mode, 1359765 The voltage generated by the motor 112 is regulated to a stable DC voltage, and is supplied to the direction lights 102 and 120, the front and rear lamps 104 and 116, and the portable device charging stand 122 such as a mobile phone/PDA/satellite navigation/MP3. FIG. 3 is the present invention. The block diagram of an embodiment of the voltage regulator is divided into two parts, a main power circuit 30 and a control circuit 34. The main power circuit 30 first provides the generator 112 with a three-phase commutator 302 and a DC capacitor C1. The input voltage rectification filter is DC, and the DC-to-DC converter 304 converts it into a stable DC output voltage Vo. The control circuit 34 returns the output voltage Vo and adjusts the responsibility of the switch by using the voltage control device 344 and the signal PWM 342. Cycle The output of the DC-to-DC converter 304 is such that the feedback output voltage Vo is equal to the reference voltage. The output voltage Vo is supplied to the charging or lighting device attached to the bicycle via the multi-slot USB output 306. The bicycle of the present invention When the AC module is connected, referring to FIG. 2, the electric power generated by the stepping pedal is fed into the commercial power. FIG. 4 is a block diagram of an embodiment of the AC module, and is divided into a main power circuit 40, a control circuit 42 and The main power circuit 40 rectifies and filters the input voltage provided by the generator into a direct current by using the commutator 402 and the direct current capacitor C1, and the rectified direct current is fed back to the control circuit 42, DC-DC. The converter 404 boosts the voltage and controls its output current to a half-sinus alternating current, and then converts the half-sinusoidal alternating current into a phase-to-phase communication with the commercial power using a line-frequency switched DC-AC converter 406. The current is fed into the mains. The current command selection means 426 of the control circuit 42 determines the power to the DC-DC converter 404 based on a manual current level command or a current level command set by the control program. The manual current level command is determined by the power knob described in Si 10 1359765. When the power knob is turned on, the knob sets the magnitude of the current command. When the power knob is turned to the minimum level and turned off, select The switch is switched so that the current command is determined by the current level command set by the control program stored in the 'computer or mobile phone connected to the bicycle. The electric current command is compared with the feedback DC current, and the error is passed through the current controller. 425 adjusts the amplitude command for generating the control voltage, and the voltage amplitude command is multiplied by a half sinusoidal signal synchronized with the mains voltage by the control voltage generator 424 to obtain a half sinusoidal control voltage, and finally compared with the sawtooth wave to generate a trigger. Signal PWM is used to control the output of DC-DC converter 404. The control of the DC-AC converter 406 is first to determine whether the mains is normal by the synchronization circuit 421, and to generate a sinusoidal signal synchronized with the mains, the sinusoidal signal is generated by the absolute value circuit 422 to generate a half sinusoidal signal for the control voltage. The generator 424 is also used to generate a low-frequency, positive-negative half-circle 180-degree square wave trigger signal through the synchronous switching controller 423, so that the DC-AC converter 406 switches to DC at a low frequency and in synchronization with the commercial power. The half sinusoidal current output from the DC φ converter is converted to an AC sinusoid to feed the mains. Since the sinusoidal current is in phase with the mains and has low distortion, the power factor is close. The synchronizing circuit 421 controls the synchronizing switch 408 of the AC side of the DC-AC converter. When the synchronizing circuit 421 judges that the mains is abnormal, the switch 408 is turned on and the operation of the DC-AC converter 406 is stopped to stop the power feeding to the mains. The interface circuit 44 receives the DC voltage, the DC current, the AC voltage, the AC current generated by the feedback circuit 40, and the encoder signal of the generator for analog-to-digital conversion, converting the signal into a USB communication format and using the USB and the computer 46. The mobile phone 48 communicates with the interface circuit 44 for accepting current commands generated by the control program in the computer 46 or 11 1359765 mobile phone 48. 5 is a block diagram of an embodiment of the charging module of the present invention. The main power circuit 50 rectifies and filters the input voltage generated by the generator 112 by using the commutator 5〇2 and the DC capacitor, and then passes through the DC_DC converter 5〇4. The battery 55 is charged. In order to enable the battery to be charged in a three-stage charging mode such as constant current, constant voltage and floating charge to ensure battery life, the output of the DC-DC converter 504 is connected in parallel with a brake circuit 506 including a brake switch q and a braking resistor R. The brake switch Q is controlled by the signal PWM2 provided by the control circuit 52. When the power generated by the generator exceeds the charging power demand, the brake switch Q starts to intercept to utilize the braking resistor R to consume a portion exceeding the battery charging power demand, so that the battery 55 does not cause a cause. Overcharged and destroyed. The control circuit 52 determines the current command according to the switching of the selection switch by the manual current level command or the programmed current level command. After the current command is compared with the feedback DC current, the error is adjusted by the current controller 526 to generate the control voltage. The control voltage is compared with the sawtooth wave to generate a trigger signal. The PWM control circuit φ 52 further includes a battery charge control circuit for providing the signal pWM2. The battery charging control circuit compares the feedback battery voltage r with the set full battery voltage command. The proportional integral (PI) controller 521 and the charging current limiter 522 obtain the battery charging current command //, and the charging current command is used. To set the rated charging current level of the battery, when the difference between the battery voltage 匕 and the voltage command is large, the battery is charged in a constant current manner; when the battery voltage R is close to the voltage command, the output of the PI controller 521 is reduced. The smuggler enters the linear region of the charging current limiter 522 and enters the constant voltage charging mode; when the battery voltage signal 匕 is equal to the voltage command factory / 12, the charging current command is used to maintain the electric power, and the set is as small as near zero. At this time, the charging current is small, and only the (four)th loss in the controller is maintained in the so-called floating state. Charging current command control, so that the charging current follows its charging, and the current controller 523 adjusts, the controller 524 and the 掸兴Α丨~ sentence

The equivalent circuit of the single phase is shown in Figure 7. The generator's potential (or speed) is proportional to the generator speed (ωηι). Under the condition of ignoring the steady-state voltage drop steady state, the output voltage of the generator is equal to the potential of the generator. After the generator output is rectified and filtered by three-phase, the DC voltage is equal to the peak-to-peak value of the output terminal and voltage. Therefore, the generator output power ρ 近似 is approximated by DC power: p 〇 = pd 〇 = k 〇 ymidc (1) where ' Idc is the rectified DC output current. 14 1359765 The mechanical input power Pm of the generator is:
Pm = Tm ⑺m (2)Pm = Tm (7)m (2)
若忽略發電機以及整流電路之損失，此時Pm=P。，故 由式1及式2可得 T τ 一 m 1 dc 一 ~7一~ k (3) 直流電流Idc正比於發電機之轉矩，而轉矩直接影響 使用者踩動腳踏板的感覺，換言之，前述實施例中，以手 ® 動或程式決定之電流命令可以改變交流模組或充電模組 中的直流電流，因此可以模擬出在各種環境下騎乘腳踏車 的效果。 本發明提出之發電腳踏車可以在行進間提供行車電 力（如腳踏車本身之照明、方向燈及手機之充電器等），回 到家中可以作為健身用之腳踏車，同時將健身所消耗之能 量轉換為電力饋入市電亦或對蓄電池充電以降低因電池 φ 充電所額外帶來之市電充損耗，另外，本發明還可以在發 電控制上結合運動模式規劃、多媒體動畫及網路通訊，形 成如Wii —般的情境式互動式電玩，將腳踏車的功用發揮 到極致。 【圖式簡單說明】 圖1係本發明一實施例的示意圖； 圖2係圖1之腳踏車架起使用時的示意圖； 圖3係本發明之電壓調節器一實施例的方塊圖； 15 1359765 圖4係本發明之交流模組一實施例的方塊圖； 圖5係本發明之充電模組一實施例的方塊圖； 7 6繪不本發明之控制程式的規劃；以及 圖7係二相永磁同步發電機的單相等效電路圖。If the loss of the generator and the rectifier circuit is neglected, Pm=P at this time. Therefore, from Equations 1 and 2, T τ - m 1 dc - 7 - 1 k (3) The DC current Idc is proportional to the torque of the generator, and the torque directly affects the user's feeling of stepping on the pedal. In other words, in the foregoing embodiment, the current command determined by the hand motion or the program can change the direct current in the AC module or the charging module, so that the effect of riding the bicycle in various environments can be simulated. The power bicycle provided by the invention can provide driving power (such as the illumination of the bicycle itself, the direction light and the charger of the mobile phone) in the traveling room, and can be used as a bicycle for fitness at home, and convert the energy consumed by the fitness into electric power. Feeding the mains or charging the battery to reduce the mains charging loss caused by the battery φ charging. In addition, the invention can also combine the motion mode planning, multimedia animation and network communication in the power generation control to form a Wii-like The contextual interactive video game takes the function of the bicycle to the extreme.
