[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present utility model provides a power supply system with impact resistance. The power supply system with impact resistance includes a first power supply module, a carbon-based capacitor module, a control module, and a second power supply module. When the air compressor starts, the control module outputs a first enabling signal, and the first small-current circuit is turned on based on the first enabling signal. Thus, the first power supply module can supply power to the air compressor. After delaying the first startup time, the control module can output a second enabling signal and a third enabling signal. The first large-current circuit is turned on based on the second enabling signal, and the first capacitor circuit is turned on based on the third enabling signal. At this time, the first power supply module can supply power to the air compressor through the first small-current circuit and the first large-current circuit, and the first power supply module can supply power to the carbon-based capacitor through the first capacitor circuit. If the instantaneous working power of the air compressor is greater than the first set value, the carbon-based capacitor module can release electrical energy within a certain time. Moreover, if the instantaneous working power of the air compressor is less than the first set value, the carbon-based capacitor module absorbs the electrical energy of the first power supply module. Therefore, the carbon-based capacitor can effectively increase the range of the instantaneous output power of the first power supply module, and the air compressor can maintain a stable working state.

[0019] When the power of the air compressor is greater than the first set value, the control module is used to output a fourth enabling signal, and the second small-current circuit is turned on based on the fourth enabling signal. Thus, the second power supply module can supply power to the air compressor. After delaying the second startup time, the control module is used to output a fifth enabling signal, and the second large-current circuit is turned on based on the fifth enabling signal. At this time, the second power supply module can supply power to the air compressor through the second small-current circuit and the second large-current circuit. Therefore, when the working power of the air compressor increases or multiple air compressors work simultaneously, the power supply system with impact resistance can supply power to the air compressor through two power supply modules. The power supply system with impact resistance can increase the output voltage, so that the voltage output by the power supply system with impact resistance matches the working power of the air compressor, and further the air compressor maintains a stable working state.

[0020] When the power of the air compressor is less than the second set value, the control module outputs a first disconnection signal and a second disconnection signal. The second high-current circuit is turned off based on the first disconnection signal, and the second capacitor circuit is turned off based on the second disconnection signal. After delaying the first disconnection time, the control module outputs a third disconnection signal, and the second low-current circuit is turned off based on the third disconnection signal. That is, when the working power of the air compressor decreases or multiple air compressors are turned off, the power supply system with impact resistance can gradually disconnect the second power supply module. Furthermore, the power supply system with impact resistance can reduce the output voltage, so that the voltage output by the power supply system with impact resistance matches the working power of the air compressor, so that the air compressor can maintain a stable working state. In this power supply system with impact resistance, if the working power of the air compressor changes, the power supply system with impact resistance can adjust the output voltage through the carbon-based capacitor module and the second power supply module. Thus, the voltage output by the power supply system with impact resistance matches the working power of the air compressor. Since the air compressor can receive a stable drive voltage, the air compressor can work stably at any working power. This effectively solves the technical problem that the existing air compressors are difficult to maintain a stable working state for a long time. Description of the Drawings

[0029] In the figure, units with similar structures are denoted by the same reference numerals.

[0030] Please refer to Figure 1 and Figure 2, the present utility model provides a power supply system 10 with impact resistance. The power supply system 10 with impact resistance includes a first power supply module 11, a carbon-based capacitor module 12, a first control module 13, a first switch module 14, a second power supply module 15, a second switch module 16, and an output module 17. The first power supply module 11 is used to generate a first power supply voltage, and the carbon-based capacitor module 12 is used to store energy for the first power supply voltage or the second power supply voltage.

[0031] Please refer to Figure 1 and Figure 2 , the first switch module 14 includes a first small current circuit 141, a first large current circuit 142, and a first capacitor circuit 143. The input end of the first small current circuit 141 is connected to the first power supply module 11, and the output end of the first small current circuit 141 is connected to the output module 17. The input end of the first large current circuit 142 is connected to the first power supply module 11, and the output end of the first large current circuit 142 is connected to the output module 17. The input end of the first capacitor circuit 143 is connected to the first power supply module 11, and the output end of the first capacitor circuit 143 is connected to the output module 17 and the carbon-based capacitor module 12. The control module 13 can output a first turn-on signal, the first small current circuit 141 can be turned on based on the first turn-on signal, and the first switch module 14 can supply power to the air compressor through the first small current circuit 141. After delaying the first startup time, the control module 13 can output a second turn-on signal and a third turn-on signal. Among them, the first startup time can be 2 seconds. The first large current circuit 142 can be turned on based on the second turn-on signal. At this time, the first switch module 14 can supply power to the air compressor through the first large current circuit 142, and the first capacitor circuit 143 can be turned on based on the third turn-on signal. When the air compressor starts, the first switch module 14 first supplies power to the air compressor through the first small current circuit 141. After delaying the first startup time, the first switch module 14 supplies power to the air compressor through the first large current circuit 142. Such a driving method can make the startup of the air compressor more stable. And after the air compressor works normally, the first switch module 14 only supplies power to the air compressor through the first large current circuit 142.

[0032] Moreover, the first power supply module 11 can supply power to the carbon-based capacitor 121 through the first capacitor circuit 143. When the first power supply module 11 supplies power to the air compressor, if the instantaneous working power of the air compressor is greater than the first set value, the carbon-based capacitor module 12 can release electrical energy within a certain time. And if the instantaneous working power of the air compressor is less than the first set value, the carbon-based capacitor module 12 absorbs the electrical energy of the first power supply module 11. Therefore, the carbon-based capacitor 121 can effectively increase the range of the instantaneous output power of the first power supply module 11.

[0033] Please refer to Figure 1 and Figure 2, the second power supply module 15 is used to generate a second power supply voltage. The second switch module 16 includes a second small current circuit 161, a second large current circuit 162, and a second capacitor circuit 163. The input end of the second small current circuit 161 is connected to the second power supply module 15, and the output end of the second small current circuit 161 is connected to the output module 17. The input end of the second large current circuit 162 is connected to the second power supply module 15, and the output end of the second large current circuit 162 is connected to the output module 17. The input end of the second capacitor circuit 163 is connected to the first power supply module 11, and the output end of the second capacitor circuit 163 is connected to the output module 17 and the carbon-based capacitor module 12. When the power of the air compressor is greater than the first set value, the control module 13 can output a fourth turn-on signal, and the second small current circuit 161 is turned on based on the fourth turn-on signal. After delaying the second start time, the control module 13 can output a fifth turn-on signal and a sixth turn-on signal. Among them, the second start time can be 2 seconds. The second large current circuit 162 is turned on based on the fifth turn-on signal, and the second capacitor circuit 163 is turned on based on the sixth turn-on signal. At this time, the second power supply module 15 can supply power to the air compressor through the second small current circuit 161 and the second large current circuit 162. When the power of the air compressor is greater than the first set value, the second switch module 16 first supplies power to the air compressor through the second small current circuit 161. After delaying the first start time, the first switch module 14 supplies power to the air compressor through the second large current circuit 162. Such a power supply method can make the voltage of the air compressor rise stably, and, after the air compressor works normally, the second power supply module 15 only supplies power to the air compressor through the second large current circuit 162.

[0034] Therefore, when the working power of the air compressor increases or multiple air compressors work simultaneously, the impact-resistant power supply system 10 can supply power to the air compressor through two power supply modules. The impact-resistant power supply system 10 can increase the output voltage, so that the voltage output by the impact-resistant power supply system 10 matches the working power of the air compressor, and then the air compressor maintains a stable working state. And, the second power supply module 15 can supply power to the carbon-based capacitor module 12 through the second capacitor circuit 163. When the working power of the air compressor increases, if the power supply voltage of the air compressor is insufficient, the air compressor has been in a low-voltage working state. Therefore, it is difficult for the air compressor to work stably.

[0035] Please refer to Figure 1 and Figure 2, the output module 17 can convert the first power supply voltage and the second power supply voltage in DC into an output voltage in AC, and the output module 17 can output the output voltage to the air compressor or the air compressor unit 18. When the power of the air compressor is less than the second set value, the control module 13 can output a first disconnection signal and a second disconnection signal. The second large current circuit 162 is turned off based on the first disconnection signal, and the second capacitor circuit 163 is turned off based on the second disconnection signal. After delaying the first disconnection time, the control module 13 can output a third disconnection signal, and the second small current circuit 161 is turned off based on the third disconnection signal. Wherein, the first disconnection time can be 2 seconds. When the power of the air compressor is less than the second set value, the second switch module 16 first turns off the second large current circuit 162 and the second capacitor circuit 163. At this time, the second switch module 16 can also supply power to the air compressor through the second small current circuit 161. After delaying the first disconnection time, the first switch module 14 turns off the second small current circuit 161. In this way, the method of gradually disconnecting the second power supply module 15 can make the voltage of the air compressor decrease stably.

[0036] When the working power of the air compressor decreases or multiple air compressors are turned off, the impact-resistant power supply system 10 can gradually disconnect the second power supply module 15. Furthermore, the impact-resistant power supply system 10 can reduce the output voltage, so that the voltage output by the impact-resistant power supply system 10 matches the working power of the air compressor, and then the air compressor maintains a stable working state. Moreover, when the first power supply module 11 and the second power supply module 15 supply power to the air compressor, if the instantaneous working power of the air compressor is less than the second set value, then the carbon-based capacitor module 12 can recover the electrical energy of the first power supply module 11 and the second power supply module 15 within a certain time. Moreover, when the instantaneous working power of the air compressor is greater than the second set value, the carbon-based capacitor module 12 can also release electrical energy. Therefore, the carbon-based capacitor 121 can effectively increase the range of the instantaneous output power of the first power supply module 11 and the second power supply module 15.

[0037] Please refer to Figure 1 and Figure 2, when the air compressor is turned off, the control module 13 outputs a fourth disconnection signal and a fifth disconnection signal. The first high-current circuit 142 is turned off based on the fourth disconnection signal, and the first capacitor circuit 143 is turned off based on the fifth disconnection signal. After a second disconnection delay time, the control module 13 outputs a sixth disconnection signal, and the first low-current circuit 141 is turned off based on the sixth disconnection signal. Wherein, the second disconnection time can be 2 seconds. When the air compressor is turned off, the first switch module 14 first turns off the first high-current circuit 142 and the first capacitor circuit 143. At this time, the first switch module 14 can also supply power to the air compressor through the first low-current circuit 141. After the second disconnection delay time, the first switch module 14 then turns off the first high-current circuit 142. This way of gradually cutting off the power can make the shutdown of the air compressor more stable.

[0038] Please refer to Figure 1 and Figure 2 , the control module 13 includes a first control unit 131, and the first control unit 131 is used to output a first activation signal and a sixth disconnection signal.

[0060] The working principle of the present utility model is as follows: When the power supply system 10 with impact resistance starts, the first control unit 131 outputs a first enabling signal, and the control terminal of the first small current contactor 1DJB receives the first enabling signal. The first small current contactor 1DJB can be turned on based on the first enabling signal, so that the first small current circuit 141 is connected, and the first switching module 14 transmits the first supply voltage to the output module 17 through the first small current circuit 141. After the first small current contactor 1DJB is turned on, after a first startup time delay, the second control unit 132 outputs a second enabling signal. The third control unit 133 outputs a third enabling signal, and the control terminal of the first large current contactor 1DJA receives the second enabling signal. The first large current contactor 1DJA can be turned on based on the second enabling signal, so that the first large current circuit 142 is connected, and the first switching module 14 transmits the first supply voltage to the output module 17 through the first large current circuit 142. At the same time, the control terminal of the first capacitor circuit contactor 2DJ receives the third enabling signal. The first capacitor circuit contactor 2DJ can be turned on based on the third enabling signal, so that the first capacitor circuit 143 is connected. The first switching module 14 transmits the first supply voltage to the carbon-based capacitor module 12 through the first capacitor circuit 143.

[0061] When the power of the air compressor is greater than the first set value, the fourth control unit 134 outputs a fourth opening signal. The control terminal of the second small current contactor 3DJB receives this fourth opening signal, and the second small current contactor 3DJB conducts based on this fourth opening signal. Thus, the second small current circuit 161 is connected, and the second switch module 16 transmits the second supply voltage to the output module 17 through the second small current circuit 161. After the second small current contactor 3DJB conducts, a second startup time is delayed. The fifth control unit 135 outputs a fifth opening signal, and the sixth control unit 136 outputs a sixth opening signal. The control terminal of the second large current contactor 3DJA receives the fifth opening signal, and the second large current contactor 3DJA can conduct based on the fifth opening signal. Thus, the second large current circuit 162 is connected, and the second switch module 16 transmits the second supply voltage to the output module 17 through the second large current circuit 162. At the same time, the control terminal of the second capacitor circuit contactor 4DJ receives the sixth opening signal. The second capacitor circuit contactor 4DJ can conduct based on the sixth opening signal, so that the second capacitor circuit 163 is connected, and the second switch module 16 transmits the second supply voltage to the carbon-based capacitor module 12 through the second capacitor circuit 163. Moreover, the impact-resistant power supply system 10 is provided with a carbon-based capacitor module 12. When the first power supply module 11 supplies power to the air compressor, if the instantaneous working power of the air compressor is greater than the first set value, the carbon-based capacitor module 12 can release electrical energy within a certain period of time. Moreover, if the instantaneous working power of the air compressor is less than the first set value, the carbon-based capacitor module 12 absorbs the electrical energy of the first power supply module 11. Therefore, the carbon-based capacitor 121 can effectively increase the range of the instantaneous output power of the first power supply module 11.

[0062] When the first power supply module 11 and the second power supply module 15 supply power to the air compressor, the instantaneous working power of the air compressor can fluctuate near the second set value. If the instantaneous working power of the air compressor is greater than the second set value, the carbon-based capacitor module 12 can release electrical energy within a certain period of time. And, if the instantaneous working power of the air compressor is less than the second set value, the carbon-based capacitor module 12 absorbs the electrical energy of the first power supply module 11 and the second power supply module 15. Therefore, the carbon-based capacitor 121 can effectively increase the range of the instantaneous output power of the first power supply module 11 and the second power supply module 15.

[0063] When the power of the air compressor is less than the second set value, the fifth control unit 135 outputs a first disconnection signal. The sixth control unit 136 outputs a second disconnection signal, and the control terminal of the second large-current contactor 3DJA receives the first disconnection signal. The second large-current contactor 3DJA can be disconnected based on the first disconnection signal, so that the second large-current circuit 162 is disconnected. At the same time, the control terminal of the second capacitor circuit contactor 4DJ receives the second disconnection signal, and the second capacitor circuit contactor 4DJ can be disconnected based on the second disconnection signal, so that the second capacitor circuit 163 is disconnected. After the second large-current contactor 3DJA is disconnected, the first disconnection time is delayed. The fourth control unit 134 outputs a third disconnection signal, the control terminal of the second small-current contactor 3DJB receives the third disconnection signal, and the second small-current contactor 3DJA can be disconnected based on the third disconnection signal, so that the second small-current circuit 161 is disconnected.

[0064] When the air compressor is turned off, the second control unit 132 outputs a fourth disconnection signal, the third control unit 133 outputs a fifth disconnection signal, and the control terminal of the first large-current contactor 1DJA receives the fourth disconnection signal. The first large-current contactor 3DJA can be disconnected based on the fourth disconnection signal, so that the first large-current circuit 142 is disconnected. At the same time, the control terminal of the first capacitor circuit contactor 2DJ receives the fifth disconnection signal. The first capacitor circuit contactor 2DJ can be disconnected based on the fifth disconnection signal, so that the first capacitor circuit 143 is disconnected. After the first large-current contactor 1DJA is disconnected, the second disconnection time is delayed, and the first control unit 131 outputs a sixth disconnection signal. The control terminal of the first small-current contactor 1DJB receives the sixth disconnection signal, and the first small-current contactor 1DJB can be disconnected based on the sixth disconnection signal, so that the first small-current circuit 141 is disconnected.

[0065] In the carbon-based capacitor module 12, when the voltage value of the carbon-based capacitor 121 is less than the first set voltage, the first start switch SA1-1 is in the off state. The second start switch SA1-2 is in the on state, and the drive battery 123 outputs a drive signal to the control terminal of the capacitor module relay 10DJ. The capacitor module relay 10DJ can be turned on based on the drive signal, so that the external power supply 122 can supply power to the carbon-based capacitor 121. When the voltage value of the carbon-based capacitor 121 is greater than or equal to the second set voltage, the first start switch SA1-1 is in the off state, the second start switch SA1-2 is in the on state, so that the external power supply 122 supplies power to the drive battery 123.

[0066] The present utility model provides a power supply system with impact resistance. The power supply system with impact resistance includes a first power supply module, a carbon-based capacitor module, a control module, and a second power supply module. When the air compressor starts, the control module outputs a first enabling signal, and a first small-current circuit is turned on based on the first enabling signal. Thus, the first power supply module can supply power to the air compressor. After delaying for a first start-up time, the control module can output a second enabling signal and a third enabling signal. A first large-current circuit is turned on based on the second enabling signal, and a first capacitor circuit is turned on based on the third enabling signal. At this time, the first power supply module can supply power to the air compressor through the first small-current circuit and the first large-current circuit, and the first power supply module can supply power to the carbon-based capacitor through the first capacitor circuit. If the instantaneous working power of the air compressor is greater than a first set value, the carbon-based capacitor module can release electrical energy within a certain time. Moreover, if the instantaneous working power of the air compressor is less than the first set value, the carbon-based capacitor module absorbs the electrical energy of the first power supply module. Therefore, the carbon-based capacitor can effectively increase the range of the instantaneous output power of the first power supply module, and the air compressor can maintain a stable working state.

[0067] When the power of the air compressor is greater than the first set value, the control module is used to output a fourth enabling signal, and a second small-current circuit is turned on based on the fourth enabling signal. Thus, the second power supply module can supply power to the air compressor. After delaying for a second start-up time, the control module is used to output a fifth enabling signal, and a second large-current circuit is turned on based on the fifth enabling signal. At this time, the second power supply module can supply power to the air compressor through the second small-current circuit and the second large-current circuit. Therefore, when the working power of the air compressor increases or multiple air compressors work simultaneously, the power supply system with impact resistance can supply power to the air compressor through two power supply modules. The power supply system with impact resistance can increase the output voltage, so that the output voltage of the power supply system with impact resistance matches the working power of the air compressor, and further the air compressor maintains a stable working state.

[0068] When the power of the air compressor is less than the second set value, the control module outputs a first disconnection signal and a second disconnection signal. The second high-current circuit is turned off based on the first disconnection signal, and the second capacitor circuit is turned off based on the second disconnection signal. After delaying the first disconnection time, the control module outputs a third disconnection signal, and the second low-current circuit is turned off based on the third disconnection signal. That is, when the working power of the air compressor decreases or multiple air compressors are turned off, the power supply system with impact resistance can gradually disconnect the second power supply module. Furthermore, the power supply system with impact resistance can reduce the output voltage so that the voltage output by the power supply system with impact resistance matches the working power of the air compressor, thereby enabling the air compressor to maintain a stable working state. In this power supply system with impact resistance, if the working power of the air compressor changes, the power supply system with impact resistance can adjust the output voltage through the carbon-based capacitor module and the second power supply module. Thus, the voltage output by the power supply system with impact resistance matches the working power of the air compressor. Since the air compressor can receive a stable driving voltage, the air compressor can operate stably at any working power. This effectively solves the technical problem that existing air compressors are difficult to maintain a stable working state for a long time.
