Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a bicycle training machine, and more particularly to a bicycle training machine that has both power supply and resistance adjustment functions. ', 【Prior Art】 According to bicycles, the popular leisure sports tools are not only sports and leisure functions, but also bicycle or cross-country vehicles. In order to improve speed and endurance, it takes a long time. Training to accumulate strength. At present, there is a so-called bicycle training device on the market, and the basic frame is provided with a resistance generating mechanism. When the user mounts the bicycle on the fixed frame, the rear wheel will be in contact with the resistance generating mechanism. When the user steps on the rear wheel of the bicycle, the resistance generating mechanism will generate a relative resistance to load the rotation of the rear wheel of the bicycle, thereby for training purposes. Weizuo and the existing resistance generating mechanism are divided according to the principle: hydraulic type, magnetoresistive type, friction type and inertia type; the effect of generating resistance: words, oil waste type and magnetoresistive type are better. However, the price is relatively high, and the wind resistance type is low. However, there is a low resistance to the inertia type. The braking force of the above-mentioned resistance production mechanism is related to the rotation speed, and the resistance braking is only at high speed when the speed is low. There is no disadvantage of m force ^ and no matter what principle is adopted to the resistance generating mechanism's function is only to generate resistance, there is no energy recovery measure for the user's movement during the movement, in other words, ^ The energy used by the user on the bicycle trainer is finally converted into a hot type, which is dissipated in the operating environment, which is a pity. 201204438 It can be seen from the above that ^. In order to achieve the training effect, if the training (4) is generating resistance and converting into kinetic energy generated by the user's transportation, the bicycle training H is relatively increased 2 and the resistance braking force speed range is increased, and its added value will be ★ . In addition, the bicycle training state does not take up space, the cost is low, and the bicycle is added (4) anger Μ I have a bicycle family, go. =, 'It is more economical than purchasing a general fitness bicycle. [Inventive content] Cause: The main purpose of this creation is to provide an early trainer with both power supply and low-speed brake function. The kinetic energy generated on the machine is used as a running generator. At the same time, the boosting principle is used to increase the induced voltage of the generator coil and increase the reverse current, so that the resistance is generated to the user, and the power supply and the resistance adjustment function are combined. The main technical means for achieving the above-mentioned purposes is mainly to enable the bicycle training machine to be provided with a motor-type resistance generating mechanism on a rear wheel support frame; wherein the 'far-motor resistance generating mechanism includes: a friction wheel set, which is The rear wheel support frame is configured to be in frictional contact with the rear wheel of the bicycle; a permanent magnet synchronous motor includes a three-phase stator coil and a rotor drive shaft; the rotor drive shaft is coupled with the friction wheel set and configured to interlock; A charging controller is mainly composed of a three-phase full-bridge switching rectifier circuit, a control unit and a battery; wherein the three-phase full-bridge switching rectifier circuit is connected to a three-phase stator coil of a permanent magnet synchronous motor Between the battery and the battery, the three-phase full-bridge switching rectifier circuit is mainly divided into three groups with six power electric 201204438 crystals. The two power transistors of each group belong to the upper and lower bridge arms, and the permanent magnets are described. The synchronous stator-phase stator coil is connected, and each power transistor has a _ diode between the source and the source, thereby allowing the user to step on the bicycle to make the rear wheel When moving, the friction wheel set will interlock the transmission shaft of the permanent magnet synchronous motor, so that the three-phase stator coil generates an induced voltage and sends it to the charging controller. The charging controller uses the control unit to modulate the three-phase full-bridge switching rectifier circuit. The switching of the power transistors in each group enables the internal inductance of each phase of the generator to be boosted, stored and discharged, and the battery is charged through the diode body. The charging path is an i-direction current during the boost conversion process. It will effectively generate a reverse torque, thereby generating resistance to the rotor drive shaft for the purpose of resistance adjustment and training. On the other hand, the energy stored on the battery through energy conversion can supply power for other electronic devices. .

The specific structure and wiring method are shown in Figure 4. The charging controller is composed of a three-phase full-bridge switching rectifier circuit 41 and a control unit .42. The charging controller 4〇 can generate the permanent magnet synchronous motor 3G & The electromotive force is stored in the battery 43 in the energy storage unit 44 according to the user's internal force setting; wherein the three-phase full-bridge switching rectifier circuit 41 is connected to the three-phase stator coil of the permanent magnet synchronous motor 3〇 Between 33 and the battery 43, the three-phase full-bridge switching rectifier circuit "includes six power transistors _, one output capacitor (four) wide-force rate electric... the source and the non-pole of the S6 are respectively connected to a diode Among them, three power transistors S1, S3, S5 & upper arm, the other two power transistors S2.S4S6, A-γ, deer, deer, έ έ ' 'Bei J is the lower bridge # 'up and down bridge Synchronous Thunder in the arm: the electric body -S1, S2, S3, S4 and S5, S6 respectively The permanent magnet Π: the three-phase stator coil 3 3 is connected. The inter-pole system of each power crystal is connected with the output end of the control unit, and the 42-year-old uses the pulse width modulation method to control the on-off. Due to the bicycle training of the present invention, the power generation part is a synchronous motor 30-series AC motor, and must be equipped with an AC-DC converter machine and a power supply and a global resistance adjustment work permanent magnet synchronous motor 3〇. The permanent magnet type can realize the adjustment of the resistance of the whole body. The AC/DC conversion 201204438 is the aforementioned three-phase full-bridge switching rectifier circuit 41, which can be achieved by the control of the control unit 42: the phase relationship between the phase current and the input voltage Controllable, can improve output voltage, improve low-order harmonics, stabilize DC output voltage, and have two-way drive function. The charging controller with resistance adjustment function explains the following: When the user starts to step on the bicycle, the rear wheel rotates and drives When the friction wheel rotates, the rotation speed of the permanent magnet synchronous motor 30 is also low due to the low rotation speed. At this time, the permanent magnet synchronous motor will be controlled by the charging controller 40. Lu Yuan 42 with three-phase full-bridge rectifier circuit 41 switches the low resistance line helmet brake control, this time into the permanent magnet synchronous motor dual switching mode.
雙開關模式主要藉由兩顆功率電晶體同步進行pWM 切換策略，以建立馬達模式下的電流路徑，達到低速亦有 阻力的效果。當導通區域為三相中的ab才目時，此時功率 電b曰體S2及S3將導通，且蓄電池43的電壓與感應電壓In the dual-switch mode, the pWM switching strategy is mainly performed by two power transistors to establish a current path in the motor mode to achieve low speed and resistance. When the conduction region is ab in the three phases, the power supply b bodies S2 and S3 will be turned on at this time, and the voltage and induced voltage of the battery 43 are turned on.

The head 5C shows the timing control diagram of the permanent magnet synchronous motor back electromotive force, armature current, position information and each power transistor switching signal at low speed. When the speed of the stepping bicycle is increased, the back electromotive force of the permanent magnet synchronous motor 30 is relatively increased, and the permanent magnet synchronous motor is also matched with the three-phase full-bridge switching rectifier circuit by the control unit 42 of the charging control benefit 4G. 41 仃 仃 仃 speed resistance brake control, at this time the permanent magnet synchronous motor enters the single 201204438 switch mode. Single-switch mode requires only one power transistor for PWM switching. 'Because the induced voltage is higher than the low speed at the forward speed', the armature current can be established without using the battery voltage to achieve the resistance and power generation effect. When the conduction region is the ab phase in the three phases, the power transistor S2 will be turned on at this time, and a current path is established via the diode connected across the power transistor S4, and the internal inductance of the generator on the circuit will be forced. Energy storage (as shown in FIG. 6A), when the power transistor S2 is turned off, the energy on the inductor will be rectified by the diodes connected on the power transistors si and S4_ and then transferred to the battery 43 for charging (as shown in FIG. 6B). As shown in the figure, it effectively achieves the function of generating electricity at the same time and generating braking resistance, wherein the longer the conduction time of each power crystal, the better the braking and power generation effect. Figure 6〇 The timing control diagram of the permanent magnet synchronous motor back electromotive force, armature current, position §fl and each power crystal on/off signal is not at low speed. In the foregoing energy conversion process, an effective output power and braking resistance will be generated, and the generation of the braking resistance is caused by the third step of the permanent magnet synchronous motor in the process of performing the boosting conversion in the charge controller 4〇. The phase _ sub-coil 33 generates a reverse torque 'and a resistance to the rotation of the rotor drive shaft %, which is reflected on the friction wheel 23 with the rotor drive shaft 34, thereby forming a resistance to the rotation of the rear wheel. Therefore, the effect of training, fitness and exercise is exerted on the user who tramples the bicycle. As for the magnitude of the resistance, the control period 7L 42 controls the on-period of each of the power transistors S1 to S6. In the foregoing embodiment, the motor type resistance generating mechanism on the rear wheel support frame 1 includes a permanent magnet type synchronous motor 3, i.e., power and resistance are generated by the single permanent magnet synchronous motor 30. As shown in FIG. 7, the second preferred embodiment of the present invention has the same basic structure as that of the previous embodiment. The difference is only that the motor-type resistance generating mechanism of the embodiment has two permanent magnets. Synchronous motors 30, 30, the two permanent magnet synchronous motors are disposed at two ends of the wheel base 22 and are driven by the same rotor drive shaft (not shown), and the two permanent magnets are synchronized. The motor is 3〇, 3〇, and there is still a charge controller (not shown in the figure) internally to perform AC/DC and boost conversion, thereby providing energy conversion/supply and resistance adjustment functions. At low speeds, the hydromagnetic synchronous motor can be connected in series, and the braking resistance can be m when the speed is high. ^ ± Two-phase hydro-magnetic synchronous motors can be used in parallel, and can be selected in the middle and high speeds.丄.i ^ ^ J to "power the ability of the trainer when staying."
