[0062] The present application embodiment provides a strength fitness equipment, please refer to Figure 1 , Figure 2 and Figure 3 The strength fitness equipment 100 includes a driving board 200 , a weight module 300 , a display module 400 and a housing 500 . The driving board 200 is used to drive the weight module 300 to work.

[0063] The driving board 200 may be a physical circuit board configured with a driving function, or the driving board 200 may be obtained by splicing at least two physical circuit sub-boards. The various circuits for realizing the driving function may be dispersedly arranged on the corresponding circuit sub-boards. When realizing the driving function, the user may splice the various circuit sub-boards into a driving board with a driving function.

[0064] The weight module 300 is used to output resistance. In some embodiments, the weight module 300 is a weight assembly, and the drive plate 200 is used to drive the weight assembly to work. In some embodiments, the weight module 300 includes a first weight assembly 31 and a second weight assembly 32, and the drive plate 200 is electrically connected to the first weight assembly 31 and the second weight assembly 32, respectively, and the drive plate 200 is used to drive the first weight assembly 31 and the second weight assembly 32 to work.

[0065] Each counterweight assembly includes a motor 33 and a winding assembly 34 . The output shaft of the motor 33 is connected to the winding assembly 34 . The motor 33 can drive the winding assembly 34 to move.

[0066] The winding assembly 34 includes a winding wheel 341 and a rope 342. The output shaft of the motor 33 is connected to the winding wheel 341. The winding wheel 341 is provided with a wire groove. The rope 342 is wound in the same wire groove. The first end of the rope 342 is used for the user to apply tension, and the part of the rope away from the first end is wound in the wire groove of the winding wheel 341.

[0067] The motor 33 can drive the winding wheel 341 to rotate with the rope 342. When the output shaft of the motor 33 moves in a first circumferential direction, the winding wheel 341 can carry the rope 342 to be wound in the wire groove. When the output shaft of the motor 33 moves in a second circumferential direction, the winding wheel 341 can carry the rope 342 out of the wire groove. The first circumferential direction is opposite to the second circumferential direction.

[0068] The display module 400 is installed on the outside of the strength fitness equipment and is electrically connected to the drive control circuit 25, and is used to provide a user interaction interface, wherein the display module can communicate and interact with the drive control circuit 25 to complete the setting of the corresponding fitness mode or other business operations. For example, the user can set resistance, training mode and other operations on the display module 400. The display module 400 can display the working status of the strength fitness equipment 100, and the working status includes normal working status or fault status, etc.

[0069] The housing 500 is used to accommodate the counterweight module 300 and the driving plate 200 , wherein the housing 500 can be configured into any shape, such as a cuboid, an ellipse, or a circle.

[0070] Please also read Figure 4 and Figure 5 The driving board 200 includes a driving board body 21, a power module 22, a power input circuit 23, an auxiliary power circuit 24, a driving control circuit 25 and an energy release circuit 26.

[0071] The driving board body 21 includes a high-voltage area 41 and a low-voltage area 42, wherein the high-voltage area 41 refers to an area where the voltage required by the circuit components arranged on the high-voltage area is higher than the preset safety voltage threshold. The low-voltage area 42 refers to an area where the voltage required by the circuit components arranged on the high-voltage area is lower than the preset safety voltage threshold. The preset safety voltage threshold is customized by the designer based on engineering experience, such as the preset safety voltage threshold is 20v or 36v, etc. The number of high-voltage areas 41 and low-voltage areas 42 can be one or more than two.

[0072] The power module 22 is arranged on the high voltage area 41 and is used to drive the counterweight module 300 to work. Figure 6 When the counterweight module 300 includes the first counterweight component 31 and the second counterweight component 32, the power module 22 includes the first power submodule 221 and the second power submodule 222. The first power submodule 221 and the second power submodule 222 are both arranged on the high voltage area and are electrically connected to the driving control circuit 25. The first power submodule 221 is used to drive the first counterweight component 31 to work, and the second power submodule 222 is used to drive the second counterweight component 32 to work.

[0073] In some embodiments, the power module 22 or the first power sub-module 221 or the second power sub-module 222 adopts an IPM (Intelligent Power Module).

[0074] The power input circuit 23 is arranged in the high voltage area 41 and is electrically connected to the power module 22, and is used to provide the working voltage for the power module. The power input circuit 23 can convert the external AC power into DC power and provide the DC power to the power module 22. The power module 22 inverts the DC power into an AC power that meets the requirements and provides it to the counterweight module 300, so as to drive the counterweight module 300 to work.

[0075] The auxiliary power supply circuit 24 is arranged on the driving board body 21 and is electrically connected to the power input circuit 23, and is used to provide auxiliary power, which can be applied to other circuit modules of the strength fitness equipment so that other circuit modules can work. Other circuit modules include display modules, drive control circuits, fans, sensors, etc.

[0076] It is understandable that the auxiliary power circuit 24 may be arranged on the high voltage area 41 , or part of the circuit in the auxiliary power circuit 24 may be arranged on the high voltage area 41 , and another part of the circuit may be arranged on the low voltage area 42 .

[0077] The drive control circuit 25 is arranged on the low voltage area 42 and is electrically connected to the power module 22 and the auxiliary power circuit 24, respectively, for controlling the power module 22. The auxiliary power circuit 24 can provide power to the drive control circuit 25 to ensure that the drive control circuit 25 can work normally. The drive control circuit 25 can output a drive signal to the power module 22. Under the DC power provided by the power input circuit 23, the power module 22 inverts the DC power into an AC power that meets the requirements according to the drive signal, thereby being able to drive the counterweight module 300 to work in different states.

[0078] The energy release circuit 26 is electrically connected between the power module 22 and the power input circuit 23 and is electrically connected to the drive control circuit 25, and is used to release the energy that is fed back to the power module 22. The energy release circuit 26 can adopt any form of energy release structure, such as releasing energy by a resistance energy dissipation method, or releasing energy by a short circuit grounding method.

[0079] When the strength fitness equipment is working, the counterweight module applies resistance to the rope according to the movement mode set by the user. In order to overcome the resistance, the user needs to pull the rope of the counterweight module to achieve the purpose of exercise. Since the counterweight module is a mutual inductance device, the counterweight module is easy to generate electrical energy during the user's stretching process. If the electrical energy is not released in time, the electrical energy is easy to damage the strength fitness equipment, wherein the electrical energy can easily flow back to the power input circuit 23 through the power module 22. The energy release circuit 26 can release the electrical energy in time to prevent the electrical energy from being retained in the strength fitness equipment and affecting the working reliability of other circuit modules of the strength fitness equipment.

[0080] As mentioned above, this embodiment opens up a high-voltage area 41 and a low-voltage area 42 on the driver board body 21, arranges the power module 22 and the power input circuit 23 associated with the high voltage in the high-voltage area 41, and arranges the drive control circuit 25 associated with the low voltage in the low-voltage area 42. The circuit layout of the driver board provided by this embodiment is reasonable, which can isolate the mutual influence between the high-voltage area 41 and the low-voltage area 42, which is conducive to improving the working reliability of the driver board and facilitating maintenance personnel to perform maintenance and overhaul. In addition, the energy release circuit 26 provided in this embodiment can release the energy that is backflowed back to the power module, so as to avoid the damage of the energy backflowed back to the power module to the previous stage circuit, thereby improving the working reliability and safety of the driver board.

[0081] In some embodiments, see Figure 7 The energy release circuit 26 includes an energy consumption switch circuit 261 and an energy consumption circuit 262. The energy consumption switch circuit 261 is electrically connected to the drive control circuit 25, and the energy consumption circuit 262 is electrically connected between the power module 22 and the power input circuit 23 and is electrically connected to the energy consumption switch circuit 261, for consuming the energy flowing back to the power module 22.

[0082] The energy consumption switch circuit 261 may adopt any form of switch structure. For example, the energy consumption switch circuit 261 adopts a relay or an electronic switch tube, and the electronic switch tube includes an NPN transistor or a MOS tube.

[0083] The energy consumption circuit 262 may adopt any impedance structure, for example, the energy consumption circuit 262 is a resistor, or a resistor network formed by connecting multiple resistors in parallel. The resistor may be a cement resistor or other resistive loads.

[0084] In some embodiments, the drive control circuit 25 controls the energy consumption switch circuit 261 to enter the on state, and the energy flowing back to the power module 22 can pass through the loop formed by the energy consumption switch circuit 261 and the energy consumption circuit 262, and the energy is consumed in the energy consumption circuit 262. For example, the electric energy generated by the counterweight module will cause the voltage of the power module 22 to increase, and the voltage sampling circuit samples the voltage of the power module 22 and transmits the voltage of the power module 22 to the drive control circuit 25. When the drive control circuit 25 detects that the voltage of the power module 22 is greater than or equal to the preset voltage threshold, it controls the energy consumption switch circuit 261 to enter the on state, and the energy flowing back to the power module 22 can flow through the energy consumption circuit 262 and the energy consumption switch circuit 261 in sequence.

[0085] In some embodiments, see Figure 8 The driving board 200 also includes an auxiliary function circuit 27, which is electrically connected to the auxiliary power supply circuit 24 and the driving control circuit 25 respectively to realize corresponding functions.

[0086] In some embodiments, the auxiliary function circuit 27 includes a fan module, a temperature acquisition module, an encoder component, a display module, a voltage sampling circuit, a current sampling circuit or an interface circuit, etc.

[0087] The fan module is used to dissipate the heat generated by the driving board 200 and / or the counterweight module 300. The fan module may include one or more fans, and the fans may be installed on the driving board 200 or in the counterweight module 300. The driving control circuit 25 may control the working power of the fan module.

[0088] The temperature acquisition module is used to collect the temperature of the driving board 200 and / or the counterweight module 300. The temperature acquisition module may include one or more temperature sensors, and the temperature sensors may be installed on the driving board 200 or in the counterweight module 300. When the driving control circuit 25 detects that the temperature collected by the temperature acquisition module is greater than the preset temperature threshold, the over-temperature protection operation is performed.

[0089] The encoder assembly is installed in the counterweight module 300 and is used to collect the rotation speed data of the counterweight module 300. When the counterweight module 300 includes a first counterweight assembly 31 and a second counterweight assembly 32, the encoder assembly includes a first encoder and a second encoder, the first encoder is installed on the first counterweight assembly 31, and the second encoder is installed on the second counterweight assembly 32. The drive control circuit 25 adjusts the rotation speed of the counterweight module 300 according to the rotation speed data collected by the encoder assembly.

[0090] The voltage sampling circuit is used to collect the voltage of the power module 22 and / or the voltage of the power input circuit 23 and / or the voltage of the auxiliary power circuit 24. When the drive control circuit 25 detects that the voltage collected by the voltage sampling circuit is greater than a preset voltage threshold, it performs an overvoltage protection operation, or when it detects that the voltage collected by the voltage sampling circuit is less than a preset voltage threshold, it performs an undervoltage protection operation.

[0091] The current sampling circuit is used to collect the current of the power module 22 and / or the current of the power input circuit 23 and / or the current of the auxiliary power circuit 24. When the drive control circuit 25 detects that the current collected by the current sampling circuit is greater than a preset current threshold, it performs an overcurrent protection operation, or when it detects that the voltage collected by the current sampling circuit is less than a preset current threshold, it performs an undercurrent protection operation.

[0092] The interface circuit is electrically connected to the drive control circuit 25 , wherein the interface circuit includes a USB interface, a power interface or other communication interfaces.

[0093] It is understandable that those skilled in the art can also configure corresponding functional modules according to business requirements, which will not be elaborated here.

[0094] In some embodiments, see Fig. 9 The high-voltage region 41 includes a first high-voltage sub-region 411, a second high-voltage sub-region 412 and a third high-voltage sub-region 413. The power module 22 is arranged on the first high-voltage sub-region 411, the power input circuit 23 is arranged on the second high-voltage sub-region 412, and part of the auxiliary power circuit 24 is arranged on the third high-voltage sub-region 413. In this embodiment, a plurality of high-voltage sub-regions isolated from each other can be opened on the driving board body 21, and part of the circuits of the power module 22, the power input circuit 23 and the auxiliary power circuit 24 associated with the high voltage can be isolated to avoid the mutual influence of the high voltages, which is conducive to improving the working reliability of the driving board.

[0095] In some embodiments, the number of the power modules 22 is two, the first high-voltage sub-region 411 can be divided into two high-voltage power regions, and one power module 22 is disposed on one high-voltage power region.

[0096] Please combine Figure 3The housing 500 is formed with a receiving cavity 51 for installing the counterweight module 300 and the driving plate 200. The number of the counterweight module 300 and the number of the power module 22 are both two. The corresponding power module 22 is electrically connected to the corresponding counterweight module 300. The two counterweight modules 300 are installed at the two ends of the receiving cavity 51.

The high-voltage power area is arranged along the length direction L of the housing. The corresponding power module 22 is arranged in the corresponding high-voltage power area along the length direction L of the housing 500.

[0097] Understandably, Fig. 9 The layout of the power module 22, power input circuit 23 and partial circuits of the auxiliary power circuit 24 in each high-voltage sub-area shown is only one implementation method. Those skilled in the art can also customize the high-voltage sub-area to which each circuit belongs according to design requirements.

[0100] Please continue reading Fig. 9 The driving board body 21 also includes a capacitor area 43, wherein the capacitor area 43 is located between the first low-voltage sub-area 421 and the second low-voltage sub-area 422, and the capacitor area 43 is used to place the electrolytic capacitor of the power input circuit 231 and / or the auxiliary power circuit 24.

[0101] This embodiment can reasonably set up multiple high-voltage sub-areas, multiple low-voltage sub-areas and capacitor areas to arrange high-voltage devices, low-voltage devices and capacitor devices. It can not only isolate the influence between high voltage and low voltage, but also isolate the influence between high voltage and high voltage and the influence between low voltage and low voltage. Moreover, it has a compact structure and a small area of ​​​​the circuit board, which is conducive to cost saving.

[0102] The power input circuit 23 can support input of AC power in a wide voltage range.

[0103] See also Fig.10The power input circuit 23 includes a filter circuit 231 and a bus rectifier circuit 232. The filter circuit 231 is electrically connected to the bus rectifier circuit 232, and the bus rectifier circuit 232 is electrically connected to the power module 22. The filter circuit 231 is used to filter the external input AC power to suppress the harmonic noise of the external AC power. The bus rectifier circuit 232 is used to rectify the AC power into a DC power.

[0104] The filter circuit 231 can adopt any structural form of filter circuit, for example, the filter circuit 231 is a π-type filter circuit. The filter circuit 231 adopts an EMI (Electromagnetic Interference) filter circuit, which can meet the EMC safety CE / RE technical requirements of different countries. The bus rectifier circuit 232 can be a full-bridge rectifier circuit or a half-bridge rectifier circuit.

[0105] In some embodiments, please refer to Fig.10 The power input circuit 23 also includes a surge protection circuit 233, which is electrically connected between the filter circuit 231 and the bus rectifier circuit 232. The surge protection circuit 233 can effectively suppress the instantaneous current generated by the power fitness equipment during instantaneous cold startup, and can also suppress the impact of instantaneous fluctuations in the mains power grid and sudden changes in indoor voltage, thereby protecting the back-end circuit from the impact of surge current.

[0106] The surge protection circuit 233 may adopt any form of circuit structure. For example, the surge protection circuit 233 is a fuse. Another example is that the surge protection circuit 233 is a circuit with surge protection function composed of a thermistor and a relay, wherein the thermistor is connected in parallel with the relay, and the relay is in a normally open state.

[0107] When the power fitness equipment is turned on, since the relay is in a normally open state, current will flow through the thermistor. Among them, the thermistor first absorbs the surge current generated instantly when the power fitness equipment enters the power-on state. When the surge current occurs, the current flowing through the thermistor is too large, the temperature of the thermistor increases, and the resistance decreases. In this way, the thermistor avoids consuming too much power while absorbing the surge current. When the power fitness equipment enters a stable state, the drive control circuit 25 controls the relay to enter a closed state, so that the current switches from flowing through the thermistor to flowing through the relay. Since the thermistor has impedance, the current flowing through the thermistor will consume energy, but when the current switches to flow through the relay, the relay will consume very little energy, so that the purpose of saving power consumption and improving the efficiency of power transmission can be achieved.

[0108] In some embodiments, please refer to Fig.10The power input circuit 23 also includes a bus energy storage circuit 234, which is electrically connected between the bus rectifier circuit 232 and the power module 22. The bus energy storage circuit 234 is used to store electrical energy and can provide the stored electrical energy to the power module 22. The bus energy storage circuit 234 can be formed by one or more electrolytic capacitors connected in parallel.

[0109] In some embodiments, see Fig.11 The power input circuit 23 also includes a power factor correction circuit 235 (Power Factor Correction, PFC), which is electrically connected between the bus rectifier circuit 232 and the bus energy storage circuit 234. The power factor correction circuit 235 can change the phase relationship between the current and voltage transmitted to the power module 22, thereby improving the efficiency of the strength fitness equipment in converting the mains power into DC high voltage, reducing reactive power, improving the power factor, and thus improving the power transmission efficiency.

[0110] In some embodiments, see Fig.12 The auxiliary power supply circuit 24 is electrically connected to the bus main line for the power input circuit 23 to provide the bus voltage to the power module 22, and the drive control circuit 25 is arranged on the high voltage area 41. The bus main line is a loop for the power input circuit 23 to provide the bus voltage to the power module 22 based on the bus. Fig.12 As shown, the auxiliary power circuit 24 is electrically connected between the power factor correction circuit 235 and the power module 22. The auxiliary power circuit 24 can provide auxiliary power for the drive control circuit 25 and the auxiliary function circuit 27, for example, the auxiliary power circuit 24 supplies power to the fan, the encoder, the display module, etc.

[0111] In addition, the auxiliary power supply circuit 24 can also receive energy that is fed back to the power module 22 and store the energy that is fed back to the power module 22. Therefore, the auxiliary power supply circuit 24 provided in the embodiment of the present application can also utilize the energy that is fed back to the power module 22 to avoid wasting the energy that is fed back to the power module 22, which is conducive to improving the efficiency of electric energy utilization.

[0112] Understandably, Fig.12 The driving board shown can be a voltage step-down circuit, wherein the auxiliary power supply circuit 24 can convert the DC voltage output by the power factor correction circuit 235 into an operating voltage required by the auxiliary function circuit 27. For example, the voltage step-down circuit can convert the DC voltage output by the power factor correction circuit 235 into a 5V voltage and / or a 3.3V voltage to meet the needs of the auxiliary function circuit 27.

[0113] In some embodiments, Fig.12 The embodiment shown differs in that, see Fig.13The power input circuit 23 and the power module 22 form a bus main circuit, the power input circuit 23, the auxiliary power circuit 24 and the power module 22 are electrically connected in sequence to form a power supply branch, and the drive control circuit 25 is arranged on the low voltage area 42. In the power supply branch, the auxiliary power circuit 24 converts the AC power of the power input circuit 23 into a DC power supply and provides the DC power supply to the power module 22. Fig.13 As shown, the auxiliary power circuit 24 is electrically connected to the filter circuit 231 to convert the AC power output by the filter circuit 231 into a DC power. It is understandable that the auxiliary power circuit 24 can also be electrically connected between the surge protection circuit 233 and the bus rectifier circuit 232.

[0114] In some embodiments, the DC power supply can help the power chip or other components of the power module 22 maintain normal operation. When the power input circuit 23 enters an abnormal state and cannot provide power to the power module 22, the auxiliary power supply circuit 24 can provide auxiliary power to the power chip of the power module 22 so that the power chip of the power module 22 can continue to work, and feedback information about the abnormal operation of the power input circuit 23 to the drive control circuit 25, and the drive control circuit 25 then reports the information about the abnormal operation of the power input circuit 23 to the display module 400, and the user can know that the strength fitness equipment is in a fault state through the display module 400.

[0115] In some embodiments, the DC power supply can also be inverted into AC power by the power module 22 to provide to the counterweight module 300. When the power input circuit 23 enters an abnormal state and cannot provide power to the power module 22, the auxiliary power circuit 24 can provide the power module 22 with the required inverted power, wherein a switch is provided between the auxiliary power circuit 24 and the power module 22, and the switch can be a relay or a contactor. When the power input circuit 23 works normally, the switch is in an open state. When the power input circuit 23 works abnormally, the switch is in a closed state, and the auxiliary power circuit 24 provides the power module 22 with the required inverted power through the switch.

[0116] In addition, the input of the auxiliary power supply circuit 24 is the AC power of the power input circuit 23, not the DC power processed by the power input circuit 23. Therefore, it can be regarded as: the auxiliary power supply circuit 24 is a power supply independent of the power input circuit 23. When the power input circuit 23 is abnormal or damaged, the auxiliary power supply circuit 24 can still provide DC power to the power module 22.

[0117] exist Fig.13In the driving board shown, the auxiliary power supply circuit 24 can not only provide working voltage to the auxiliary function circuit 27, but also provide DC power to the power module 22. This can enhance the diversity of power input received by the power module 22, which is beneficial to improving the working robustness of the driving board.

[0118] In some embodiments, please refer to Fig.14 and Fig.15 The auxiliary power supply circuit 24 includes an auxiliary rectifier circuit 241 , a power supply processing circuit 242 and a voltage processing circuit 243 .

[0119] The auxiliary rectifier circuit 241 is arranged on the high voltage area 41, for example, the auxiliary rectifier circuit 241 is arranged on the third high voltage sub-area 413. The auxiliary rectifier circuit 241 is electrically connected to the power input circuit 242, and is used to convert the AC power of the power input circuit 23 into a DC power. The auxiliary rectifier circuit 241 can adopt a full-bridge rectifier circuit or a half-bridge rectifier circuit.

[0120] The power processing circuit 242 includes a coupled primary power circuit 244 and a secondary power circuit 245, the primary power circuit 244 is electrically connected to the auxiliary rectifier circuit 241, and the secondary power circuit 245 is arranged on the low voltage area 42, for example, the secondary power circuit 245 is arranged on the first low voltage sub-area 421. The power processing circuit 242 is used to convert the DC power into a target voltage, for example, the target voltage is 12V.

[0121] It can be understood that the power processing circuit 242 can be a flyback transformer or a forward transformer, wherein the primary power supply circuit 244 is a circuit on the primary side of the flyback transformer or the forward transformer, and the secondary power supply circuit 245 is a circuit on the secondary side of the flyback transformer or the forward transformer.

[0122] It can also be understood that the auxiliary rectification circuit 241 and the power processing circuit 242 can form a flyback power supply or a forward power supply.

[0123] The voltage processing circuit 243 is electrically connected to the secondary power supply circuit 245, and is used to convert the target voltage into an operating voltage, such as converting a 12V target voltage into a 5V or 3.3V operating voltage, or converting a 12V target voltage into a 20V voltage.

[0124] In this embodiment, when the auxiliary power supply circuit 24 can directly introduce high-voltage AC power for processing, and the target voltage output by the secondary power supply circuit 245 can be provided to the drive control circuit 25 and the auxiliary function circuit 27 in the low-voltage area, this embodiment configures the power supply processing circuit 242 to be a coupled primary power supply circuit 244 and a secondary power supply circuit 245, and arranges the primary power supply circuit 24 in the high-voltage area and the secondary power supply circuit 245 in the low-voltage area. In this way, the high voltage from the primary power supply circuit 24 side will not affect the low voltage on the secondary power supply circuit 245 side, and will not be transmitted to the drive control circuit 25 and the auxiliary function circuit 27, which is beneficial to promoting the working reliability and safety of the drive board, and is also beneficial to the subsequent maintenance and overhaul work.

[0125] In some embodiments, please refer to Fig.14 The auxiliary power supply circuit 24 also includes an auxiliary energy storage circuit 240, which is electrically connected between the auxiliary rectification circuit 241 and the power processing circuit 242 and is used to store the DC power output by the auxiliary rectification circuit 241. When the power input circuit 23 works abnormally, the auxiliary energy storage circuit 240 can also provide power for the subsequent circuit.

[0126] The auxiliary energy storage circuit 240 may be an electrolytic capacitor or a super capacitor with a relatively large capacitance value.

[0127] In some embodiments, please refer to Fig.16 and Fig.17 The voltage processing circuit 243 includes a voltage isolation circuit 246 and a voltage conversion circuit 247 .

[0128] The voltage isolation circuit 246 includes a coupled primary isolation circuit 248 and a secondary isolation circuit 249, wherein the primary isolation circuit 248 is arranged on the low voltage area 42 and electrically connected to the secondary power supply circuit 245, for example, the primary isolation circuit 248 is arranged on the first low voltage sub-area 421, and the secondary isolation circuit 249 is electrically connected to the power module 22. The voltage isolation circuit 246 is used to convert the target voltage into the working voltage required to match the power module 22, for example, converting the target voltage of 12V into a working voltage of 20V and providing it to the power module 22.

[0129] It can be understood that when the counterweight module 300 includes a first counterweight component 31 and a second counterweight component 32, and the power module 22 includes a first power sub-module 221 and a second power sub-module 222, the number of the voltage isolation circuit 246 is at least two, and the secondary side isolation circuit 249 of one voltage isolation circuit 246 is electrically connected to the first power sub-module 221, and the secondary side isolation circuit 249 of the other voltage isolation circuit 246 is electrically connected to the second power sub-module 222.

[0130] It can also be understood that the voltage isolation circuit 246 can be a DC-DC isolation circuit, wherein the DC-DC isolation circuit can be a boost isolation circuit or a buck isolation circuit or a boost-buck isolation circuit.

[0131] The voltage conversion circuit 247 is electrically connected to the secondary power supply circuit 245 and the drive control circuit 25, respectively. For example, the voltage conversion circuit 247 includes a first voltage conversion subcircuit and a second voltage conversion subcircuit, the first voltage conversion subcircuit converts the target voltage into a first voltage, and the second voltage conversion subcircuit converts the target voltage into a second voltage, the first voltage is different from the second voltage, for example, the first voltage is 3.3V, and the second voltage is 5V.

[0132] This embodiment can configure the voltage isolation circuit into a coupled primary isolation circuit and a secondary isolation circuit, wherein the primary isolation circuit 248 is arranged on the low-voltage area 42 and is electrically connected to the secondary power supply circuit 245, and the secondary isolation circuit 249 is electrically connected to the power module 22. In this way, the high voltage from the power module 22 can be isolated from the primary isolation circuit 248 by the secondary isolation circuit 249, thereby preventing the high voltage from the power module 22 from affecting the low-voltage area where the secondary power supply circuit 245 is located, which is beneficial to improving the working reliability and safety of the driver board.

[0133] In some embodiments, see Fig.18 The driving control circuit 25 includes a driving circuit 251 and a micro-control circuit 252 .

[0134] The drive circuit 251 is electrically connected to the power module 22 and is used to drive the power module 22. The microcontrol circuit 252 is arranged on the low-voltage area 42 and is electrically connected to the drive circuit 251 and the auxiliary power circuit 24, respectively, and is used to control the drive circuit 251. As the control core of the strength fitness equipment, the microcontrol circuit 252 can complete various business logics, such as: controlling the speed and air volume of the fan respectively to adjust the temperature, monitoring the working condition of the drive board, performing voltage detection and current detection on the power module, detecting and processing the speed of the counterweight module, monitoring the inner rotor temperature of the counterweight module, controlling the resistance output by the counterweight module according to the exercise mode set by the user, communicating with the host computer through the interface circuit, etc.

[0135] It can be understood that when the counterweight module 300 includes a first counterweight component 31 and a second counterweight component 32, and the power module 22 includes a first power sub-module 221 and a second power sub-module 222, the number of drive circuits 251 is at least two, one drive circuit 251 is electrically connected to the first power sub-module 221, and the other drive circuit 251 is electrically connected to the second power sub-module 222.

[0136] In some embodiments, the micro-control circuit 252 may be a microprocessor or may be composed of two or more microprocessors.

[0138] In this embodiment, the microcontroller circuit 252 is configured into a master-slave control architecture. The master control circuit 257 can interact with the user through the display module or the communication module of the strength fitness equipment, receive tasks issued by the user, and collaboratively control the first slave control circuit 255 and the second slave control circuit 256 according to the issued tasks, wherein the first slave control circuit 255 controls the first counterweight assembly 31 through the first power sub-module 221 according to the control command issued by the master control circuit 257, and the second slave control circuit 256 controls the second counterweight assembly 32 through the second power sub-module 222 according to the control command issued by the master control circuit 257, or the first slave control circuit 255 or the second slave control circuit 256 can send various types of business information to the master control circuit 257, thereby realizing communication interaction between the master control circuit 257, the first slave control circuit 255 and the second slave control circuit 256.

[0139] The main control circuit 257 sends the control information of the motor on each side to the slave control circuit on the corresponding side for control. The specific control logic is executed by the slave control circuit on the corresponding side. This is beneficial to improving the control speed of the main control circuit 257, and the slave control circuit on the corresponding side can quickly respond to the requirements of the main control circuit 257 to complete the control of the motor, which is also beneficial to improving the timeliness and real-time performance of the motor control, while also reducing the design difficulty of the main control circuit 257.

[0140] Please also read Fig. 20 , Fig.21 and Fig. 22Each driving sub-circuit includes a coupled optocoupler primary circuit 253 and an optocoupler secondary circuit 254 .

The optocoupler secondary circuit 254 is arranged on the high-voltage area 41 and electrically connected to the power module 22 .

[0141] This embodiment can configure the driving sub-circuit into a coupled optocoupler primary circuit 253 and an optocoupler secondary circuit 254, that is, the driving sub-circuit is an optocoupler isolation driving circuit. Although the optocoupler secondary circuit 254 is electrically connected to the power module 22 in the high-voltage area, based on the unidirectional conduction mode between the optocoupler primary circuit 253 and the optocoupler secondary circuit 254, and the optocoupler primary circuit 253 and the optocoupler secondary circuit 254 do not share the same ground terminal, wherein the ground terminal of the optocoupler primary circuit 253 is in the low-voltage area, and the ground terminal of the optocoupler secondary circuit 254 is in the high-voltage area. Therefore, the high-voltage influence from the high-voltage area cannot be transmitted to the optocoupler primary circuit 253 through the optocoupler secondary circuit 254, that is, the optocoupler primary circuit 253 and the optocoupler secondary circuit 254 shield the influence of the high voltage from the high-voltage area, ensuring that the circuit devices on the low-voltage side can work reliably.
