[0062] First embodiment:

[0063] According to a first embodiment of the present application, a generator assembly is provided. Figure 1 and Figure 2 The generator assembly includes a generator 90, a tension transmitter 94, and a tension control circuit. The generator 90 is provided with a tension handle 92. When the tension handle 92 is pulled, the generator 90 generates electricity to generate alternating current.

[0064] A tension transmitter 94 is connected to the tension handle 92. The tension transmitter 94 can be an electric tension transmitter 94 that converts pressure into an electric signal, thereby outputting tension. The tension transmitter 94 outputs a first voltage linearly corresponding to the tension applied by the tension handle 92. The first voltage output by the tension transmitter 94 is linearly related to the tension applied by the tension handle 92. Alternatively, the first voltage output by the tension transmitter 94 can be directly proportional to the tension applied by the tension handle 92, increasing or decreasing with increasing or decreasing tension applied by the tension handle 92.

[0065] The tension control circuit includes a conversion circuit and a current controller 30. The conversion circuit is electrically connected to the generator 90 and can convert the AC power generated by the generator 90 into DC power. The conversion circuit can specifically include a rectifier 10 and a step-up / step-down power supply module 20.

[0066] Rectifier 10 is a device that converts AC power into DC power and can be used to power a device. Rectifier 10 has UV and W terminals, and the three-phase AC power generated by generator 90 is connected to these terminals. Rectifier 10 converts the AC power generated by generator 90 into DC power, which can then be used to charge battery 80, power the entire circuit system, or provide external power.

[0067] The step-up / step-down power supply module 20 is electrically connected to the rectifier 10. The step-up / step-down power supply module 20 converts the DC power rectified by the rectifier 10 into DC power of a stable voltage. Specifically, the step-up / step-down power supply module 20 can be implemented as a DC-DC converter. A DC-DC converter converts DC power of a certain voltage to DC power of another voltage for practical use.

[0068] The current controller 30 is electrically connected to the step-up / step-down power module 20 of the conversion circuit. The current controller 30 adjusts the DC power outputted by the step-up / step-down power module 20 to a controllable current value, which is then fed into the terminals of the battery 80, thereby charging the battery 80 at the set current. Optionally, the current controller 30 may include a transistor, a current-controlling element that regulates current by controlling the collector current with the base current.

[0069] The tension control circuit can convert the AC power generated by the generator 90 into DC power through a conversion circuit, and then adjust the DC power to a controllable current value through the current controller 30 for connection to the battery 80. The energy of the generator 90 can be effectively absorbed and stored for recycling, without being wasted.

[0070] In this embodiment, please refer to Figure 1 and Figure 2The tension control circuit may further include a comparison control circuit, which includes a single chip microcomputer 50 and a voltage comparator 40 .

[0071] The single-chip microcomputer 50, also known as a single-chip microcontroller, integrates a computer system onto a single chip, integrating data calculation and processing capabilities into the chip to achieve high-speed data processing. The T and R terminals of the single-chip microcomputer 50 are connected to external communication terminals to communicate with external devices or components, thereby obtaining externally input weight data. For example, the externally input weight data can be selected or set by the user.

[0072] The single-chip microcomputer 50 is provided with a DAC module (digital / analog conversion module), which can convert digital signals and output voltage analog signals. The single-chip microcomputer 50 can perform DAC conversion on the external input weight data and output a second voltage value corresponding to the weight data.

[0073] The voltage comparator 40 is a circuit for identifying and comparing input signals and is a basic unit circuit of the non-sinusoidal wave generating circuit. The voltage comparator 40 is provided with a positive input terminal, a negative input terminal and an output terminal.

[0074] The positive input terminal of the voltage comparator 40 is electrically connected to the single chip microcomputer 50 , so that the voltage comparator 40 can obtain the second voltage value converted by the DAC of the single chip microcomputer 50 .

[0075] The negative input terminal of the voltage comparator 40 is electrically connected to the input terminal F+ of the tension transmitter 94 , so that the voltage comparator 40 can obtain the first voltage value linearly corresponding to the output of the tension transmitter 94 in response to the tension of the tension handle 92 of the generator 90 .

[0076] The output terminal of the voltage comparator 40 is electrically connected to the base of the transistor, and is used to control the controllable current value output by the current controller 30 to adjust the output power of the generator 90 .

[0077] After the voltage comparator 40 obtains the first voltage value and the second voltage value, it can compare the first voltage value with the second voltage value and determine the magnitude of the two values, and control and adjust the output voltage of the voltage comparator 40 according to the determination result, thereby adjusting the controllable current value output by the current controller 30.

[0078] If the first voltage value is greater than the second voltage value, the output voltage of the voltage comparator 40 decreases, controlling the controllable current value output by the current controller 30 to decrease, thereby reducing the output power of the generator 90. This increases the pulling force of the pulling handle 92, implementing negative feedback control, which ultimately ensures that the actual pulling force of the pulling handle 92 and the pulling force corresponding to the counterweight data are equal, achieving equilibrium.

[0079] If the first voltage value is determined to be less than the second voltage value, the output voltage of the voltage comparator 40 increases, controlling the increase in the controllable current value output by the current controller 30, thereby increasing the output power of the generator 90. This reduces the pulling force of the pulling handle 92, implementing negative feedback control, which ultimately ensures that the actual pulling force of the pulling handle 92 and the pulling force corresponding to the counterweight data are equal, achieving equilibrium.

[0080] In this embodiment, the tension control circuit can be integrated on the same circuit board. The tension control circuit has a simple structure and is easy to assemble and connect with the generator 90.

[0081] The tension control circuit can recover the energy of the generator 90 through the tension control method. Figure 1 and Figure 2 , the tension control method comprises the following steps:

[0082] Step 1: rectify the AC power generated by the generator 90 into DC power.

[0083] Specifically, the three-phase AC power generated by the generator 90 is connected to the UVW terminals of the rectifier 10. The rectifier 10 rectifies the AC power generated by the generator 90 into DC power for subsequent charging of the battery 80, or for powering the entire circuit system or an external device.

[0084] Step 2: Convert the rectified DC power into DC power with a stepped-up or stepped-down voltage.

[0085] Specifically, the step-up / step-down power supply module 20 may adopt a DC-DC converter, which converts the DC power rectified by the rectifier 10 into DC power with a stable voltage for practical use.

[0086] Step three: adjust the DC power with a stable voltage to a controllable current value to connect to the battery 80.

[0087] Specifically, the step of adjusting the DC power with a stable voltage to a controllable current value may include the following steps:

[0088] The single chip microcomputer 50 converts the externally input counterweight data into a second voltage value; the voltage comparator 40 obtains the first voltage value linearly corresponding to the output of the tension transmitter 94 in response to the tension of the tension handle 92 of the generator 90.

[0089] The voltage comparator 40 compares the first voltage value with the second voltage value.

[0090] Based on the result of comparing the first voltage value with the second voltage value, the voltage comparator 40 can perform corresponding processing. If the first voltage value is determined to be greater than the second voltage value, the output voltage of the comparison control circuit decreases, and the controllable current value output by the current controller 30 is controlled to decrease, thereby reducing the output power of the generator 90. If the first voltage value is determined to be less than the second voltage value, the output voltage of the comparison control circuit increases, and the controllable current value output by the current controller 30 is controlled to increase, thereby increasing the output power of the generator 90.

[0091] In addition, please refer to Figure 2 The step-up / step-down power supply module 20 can also be electrically connected to the output terminals of V+V- to supply power to the entire circuit system or the outside.

[0092] The tension control circuit captures the first voltage value linearly output by the tension transmitter 94 in response to the tension applied to the tension handle 92 of the generator 90, as well as the externally input counterweight data, and converts the externally input counterweight data into a second voltage value. By comparing the second voltage value with the first voltage value, the controllable current output by the current controller 30 is adjusted accordingly, thereby adjusting the output power of the generator 90 to achieve tension control. This ultimately ensures that the actual tension applied to the tension handle 92 and the tension corresponding to the counterweight data are equal, achieving equilibrium.

[0093] Second embodiment:

[0094] According to a second embodiment of the present application, another generator assembly is provided. Figure 3 and Figure 4 The generator assembly includes a generator 90, a tension transmitter 94, and a tension control circuit. The generator 90 is provided with a tension handle 92. When the tension handle 92 is pulled, the generator 90 generates electricity to generate alternating current.

[0095] A tension transmitter 94 is connected to the tension handle 92. The tension transmitter 94 can be an electric tension transmitter 94 that converts pressure into an electric signal, thereby outputting tension. The tension transmitter 94 outputs a first voltage linearly corresponding to the tension applied by the tension handle 92. The first voltage output by the tension transmitter 94 is linearly related to the tension applied by the tension handle 92. Alternatively, the first voltage output by the tension transmitter 94 can be directly proportional to the tension applied by the tension handle 92, increasing or decreasing with increasing or decreasing tension applied by the tension handle 92.

[0096] The tension control circuit includes a conversion circuit and a current controller 30. The conversion circuit is electrically connected to the generator 90 and can convert the AC power generated by the generator 90 into DC power. The conversion circuit can specifically include a rectifier 10 and a step-up / step-down power supply module 20.

[0097] Rectifier 10 is a device that converts AC power into DC power and can be used to power a device. Rectifier 10 has UV and W terminals, and the three-phase AC power generated by generator 90 is connected to these terminals. Rectifier 10 converts the AC power generated by generator 90 into DC power, which can then be used to charge battery 80, power the entire circuit system, or provide external power.

[0098] The step-up / step-down power supply module 20 is electrically connected to the rectifier 10. The step-up / step-down power supply module 20 converts the DC power rectified by the rectifier 10 into DC power of a stable voltage. Specifically, the step-up / step-down power supply module 20 can be implemented as a DC-DC converter. A DC-DC converter converts DC power of a certain voltage to DC power of another voltage for practical use.

[0099] The current controller 30 is electrically connected to the step-up / step-down power module 20 of the conversion circuit. The current controller 30 adjusts the DC power outputted by the step-up / step-down power module 20 to a controllable current value, which is then fed into the terminals of the battery 80, thereby charging the battery 80 at the set current. Optionally, the current controller 30 may include a transistor, a current-controlling element that regulates current by controlling the collector current with the base current.

[0100] The tension control circuit can convert the AC power generated by the generator 90 into DC power through a conversion circuit, and then adjust the DC power to a controllable current value through the current controller 30 for connection to the battery 80. The energy of the generator 90 can be effectively absorbed and stored for recycling, without being wasted.

[0101] In this embodiment, please refer to Figure 3 and Figure 4 The tension control circuit may further include a comparison control circuit. The comparison control circuit includes a single chip microcomputer 50.

[0102] The single-chip microcomputer 50, also known as a single-chip microcontroller, integrates a computer system onto a single chip, integrating data calculation and processing capabilities into the chip to achieve high-speed data processing. The T and R terminals of the single-chip microcomputer 50 are connected to external communication terminals to communicate with external devices or components, thereby obtaining externally input weight data. For example, the externally input weight data can be selected or set by the user.

[0103] The single-chip microcomputer 50 is provided with a DAC module (digital / analog conversion module), which can convert digital signals and output voltage analog signals. The single-chip microcomputer 50 can perform DAC conversion on the external input weight data and output a second voltage value corresponding to the weight data.

[0104] The single chip microcomputer 50 is electrically connected to the input terminal F+ of the tension transmitter 94 , so that the single chip microcomputer 50 can obtain the first voltage value linearly corresponding to the output of the tension transmitter 94 in response to the tension of the tension handle 92 of the generator 90 .

[0105] The output terminal of the single chip microcomputer 50 is electrically connected to the base of the transistor, and is used to control the controllable current value output by the current controller 30 to adjust the output power of the generator 90.

[0106] After obtaining the first voltage value and the second voltage value, the single chip microcomputer 50 can compare the first voltage value with the second voltage value and determine the magnitude of the two values, and control and adjust the controllable current value output by the current controller 30 according to the determination result.

[0107] If the first voltage value is greater than the second voltage value, the microcontroller 50 controls the current controller 30 to reduce the controllable current value, thereby reducing the output power of the generator 90. This increases the pulling force of the pulling handle 92, implementing negative feedback control, so that the actual pulling force of the pulling handle 92 and the pulling force corresponding to the counterweight data are ultimately equal, achieving balance.

[0108] If the first voltage value is determined to be less than the second voltage value, the microcontroller 50 controls the current controller 30 to increase the controllable current value, thereby increasing the output power of the generator 90. This reduces the pulling force of the pulling handle 92, implementing negative feedback control, which ultimately ensures that the actual pulling force of the pulling handle 92 and the pulling force corresponding to the counterweight data are equal, achieving equilibrium.

[0109] In this embodiment, the tension control circuit can be integrated on the same circuit board. The tension control circuit has a simple structure and is easy to assemble and connect with the generator 90.

[0110] The tension control circuit can recover the energy of the generator 90 through the tension control method. Figure 3 and Figure 4 , the tension control method comprises the following steps:

[0111] Step 1: rectify the AC power generated by the generator 90 into DC power.

[0112] Specifically, the three-phase AC power generated by the generator 90 is connected to the UVW terminals of the rectifier 10. The rectifier 10 rectifies the AC power generated by the generator 90 into DC power for subsequent charging of the battery 80, or for powering the entire circuit system or an external device.

[0113] Step 2: Convert the rectified DC power into DC power with a stepped-up or stepped-down voltage.

[0114] Specifically, the step-up / step-down power supply module 20 may adopt a DC-DC converter, which converts the DC power rectified by the rectifier 10 into DC power with a stable voltage for practical use.

[0115] Step three: adjust the DC power with a stable voltage to a controllable current value to connect to the battery 80.

[0116] Specifically, the step of adjusting the DC power with a stable voltage to a controllable current value may include the following steps:

[0117] The single chip microcomputer 50 obtains the first voltage value linearly output by the tension transmitter 94 in response to the tension of the tension handle 92 of the generator 90; and converts the externally input counterweight data into a second voltage value.

[0118] The single chip microcomputer 50 compares the first voltage value with the second voltage value.

[0119] Based on the result of comparing the second voltage value with the first voltage value, the microcontroller 50 can perform corresponding processing. If the first voltage value is determined to be greater than the second voltage value, the microcontroller 50 controls the controllable current value output by the current controller 30 to decrease, thereby reducing the output power of the generator 90. If the first voltage value is determined to be less than the second voltage value, the microcontroller 50 controls the controllable current value output by the current controller 30 to increase, thereby increasing the output power of the generator 90.

[0120] Also, see Figure 3 The step-up / step-down power supply module 20 can also be electrically connected to the output terminals of V+V- to supply power to the entire circuit system or the outside.

[0121] The tension control circuit captures the first voltage value linearly output by the tension transmitter 94 in response to the tension applied to the tension handle 92 of the generator 90, as well as the externally input counterweight data, and converts the externally input counterweight data into a second voltage value. By comparing the second voltage value with the first voltage value, the controllable current output by the current controller 30 is adjusted accordingly, thereby adjusting the output power of the generator 90 to achieve tension control. This ultimately ensures that the actual tension applied to the tension handle 92 and the tension corresponding to the counterweight data are equal, achieving equilibrium.

[0122] In this application, the tension control circuit can convert the alternating current generated by the generator into direct current through a conversion circuit, and the current controller adjusts the direct current to a controllable current value for connection to the battery. The energy of the generator can be effectively absorbed and stored for recycling, without being wasted.

[0123] The tension control circuit captures a first voltage value linearly output by the tension transmitter in response to the tension in the generator's tension handle, as well as externally input counterweight data, and converts the externally input counterweight data into a second voltage value. By comparing the second voltage value with the first voltage value, the circuit adjusts the controllable current output by the current controller, thereby adjusting the generator's output power to achieve tension control. This ultimately ensures that the actual tension in the tension handle and the tension corresponding to the counterweight data are equal, achieving equilibrium.
