[0002] The parking air conditioner directly supplies power to the indoor and outdoor electric control through the battery. The outdoor electric control receives power and then receives the indoor unit start-up command to start the compressor and outdoor fan and other loads.

The parking air conditioner outdoor unit component electric control is still connected to the battery when in standby mode.

[0003] However, when the vehicle is parked, the outdoor fan is always connected to the battery. When the outdoor electronic control and other loads are not disconnected from the power supply, they will continue to consume the battery power, usually at least 1W per hour. That is, when the parked air conditioner is on standby for a long time, there will be a phenomenon of wasted power, resulting in energy loss. Summary of the invention

[0014] Wherein, the control method of the air conditioner outdoor unit is executed by the air conditioner outdoor unit control circuit.

[0015] The beneficial effect of the present application is as follows: Different from the prior art, the present application sets a switch component between the power supply and the air-conditioning outdoor unit component, and couples a control device to the switch component. When parking, the control device outputs a low-level signal or a cutoff signal output to control the switch component to disconnect, so that the power supply cannot supply power to the air-conditioning outdoor unit component.

[0024] See also Figure 1 , Figure 1 It is a structural block diagram of an embodiment of an air conditioner outdoor unit control circuit provided in the present application.

[0025] The present application provides an air conditioner outdoor unit control circuit, such as Figure 1As shown, an air conditioner outdoor unit control circuit of this embodiment includes: a control device 10, a switch component 20 and an adjustment device 50. The switch component 20 is coupled to the control device 10, the power supply 30 and the air conditioner outdoor unit component 40. Under the control of the control device 10, the switch component 20 conducts the power supply 30 and the air conditioner outdoor unit component 40, so that the power supply 30 supplies power to the air conditioner outdoor unit component 40. Or the power supply 30 is disconnected from at least part of the connection between the air conditioner outdoor unit component 40 and the air conditioner outdoor unit component 40, so that the power supply 30 cannot supply power to the air conditioner outdoor unit component 40. The adjustment device 50 is coupled to the air conditioner outdoor unit component 40, and the other end is coupled to the power supply 30 to adjust the working state of the air conditioner outdoor unit component 40. Among them, the control device 10 and the adjustment device 50 can be supplied with power to the air conditioner outdoor unit component 40 respectively, and can also be coupled to the power supply 30, which is not specifically limited in this application. In this embodiment, the air conditioner outdoor unit assembly specifically includes the air conditioner outdoor unit and the control circuit power supply. When the control device 10 controls the switch assembly 20 to be turned on, the power supply 30 supplies power to the control circuit power supply, so that the control circuit power supply is turned on to control the operation of the air conditioner outdoor unit. When the control device 10 controls the switch assembly 20 to be turned off, the power supply 30 stops supplying power to the control circuit power supply, so that the air conditioner outdoor unit stops working. In other embodiments, the air conditioner outdoor unit assembly may also include a signal receiving device to receive a signal for controlling the air conditioner external switch, so as to control the working state of the air conditioner outdoor unit.

[0026] In this embodiment, the switch assembly 20 is coupled to the control device 10, and the control assembly can control the switch assembly 20 to be turned on or off, thereby turning on or off the power supply 30 and the air-conditioning outdoor unit assembly 40. When the vehicle is parked, since the power supply 30 and the air-conditioning outdoor unit assembly 40 are continuously connected and turned on, the air-conditioning outdoor unit assembly 40 continuously consumes the power of the power supply 30. The switch assembly 20 is set between the power supply 30 and the air-conditioning outdoor unit assembly 40 to disconnect the connection between the air-conditioning outdoor unit assembly 40 and the power supply 30, so that the air-conditioning outdoor unit assembly 40 is disconnected from the power supply 30 when not working, so that the air-conditioning outdoor unit assembly 40 has no energy consumption. Specifically, when the vehicle is parked, the output end of the control device 10 outputs a low-level signal or a cut-off signal output, and controls the switch assembly 20 to be disconnected, so that the power supply 30 cannot supply power to the air-conditioning outdoor unit assembly 40, and the air-conditioning outdoor unit assembly 40 no longer consumes the power of the power supply 30. When the air conditioner outdoor unit assembly 40 needs to be turned on, the output end of the control device 10 outputs a high-level signal to control the switch assembly 20 to be turned on, so that the power supply 30 is turned on the air conditioner outdoor unit assembly 40, and the power supply 30 supplies power to the air conditioner outdoor unit assembly 40.

[0027] In an optional embodiment, the air conditioner outdoor unit assembly 40 is coupled to the regulating device 50, which can be specifically connected through a communication connection, for example, a flexible circuit can be used for connection, and this application does not make specific limitations here. The regulating device 50 is powered by the power supply 30. When the air conditioner outdoor unit assembly 40 needs to be turned on, the control device 10 outputs a high-level signal, so that the power supply 30 supplies power to the air conditioner outdoor unit assembly 40, and the regulating device 50 regulates the air conditioner outdoor unit assembly 40, which can be used to control the operating power of the air conditioner outdoor unit assembly 40. Among them, the air conditioner outdoor unit assembly 40 can specifically include a compressor and a fan. The regulating device 50 controls the operating power of the compressor and controls the speed of the fan. A variety of modes can be set on the regulating device 50 to control the compressor and the fan accordingly. The mode can be set according to user needs, and this application does not make specific limitations here.

[0028] In the above manner, by setting a switch component 20 between the power supply 30 and the air-conditioning outdoor unit component 40, and coupling the control device 10 to the switch component 20, when parking, the control device 10 outputs a low-level signal or a cutoff signal output, and controls the switch component 20 to disconnect, so that the power supply 30 cannot supply power to the air-conditioning outdoor unit component 40. Since the power supply 30 and the air-conditioning outdoor unit component 40 are disconnected, the air-conditioning outdoor unit component 40 is effectively prevented from continuing to consume power due to the connection with the power supply 30.

[0029] In an optional embodiment, if Figure 2 As shown, the switch assembly 20 includes a transistor 201 and a field effect transistor 202, the base of the transistor 201 is coupled to the control device 10, and the emitter of the transistor 201 is grounded. The gate of the field effect transistor 202 is connected to the collector of the transistor 201, the air conditioner outdoor unit assembly 40 is connected to the drain of the field effect transistor 202, and the source of the field effect transistor 202 is coupled to the power supply 30. When the connection between the power supply 30 and the air conditioner outdoor unit assembly 40 needs to be disconnected for parking, the output end of the control device 10 outputs a low-level signal and a cut-off signal output, the base of the transistor 201 has no signal input or receives a low-level signal, so that the transistor 201 is disconnected, and the disconnection of the transistor 201 causes the field effect transistor 202 to be cut off, thereby disconnecting the power supply 30 from the air conditioner outdoor unit assembly 40, and the air conditioner outdoor unit assembly 40 has no energy consumption. That is, the control device 10 controls the transistor 201 to be disconnected, so that the power supply 30 is cut off from flowing through the field effect transistor 202, so that the power supply 30 is disconnected from the air-conditioning outdoor unit assembly 40, effectively preventing the air-conditioning outdoor unit assembly 40 from continuously consuming the energy of the power supply 30 when the air-conditioning outdoor unit assembly 40 is not needed during parking.

[0030] In this embodiment, when the air conditioner outdoor unit assembly 40 needs to be turned on, the control device 10 outputs a high-level signal. After the base of the transistor 201 receives the high-level signal, since the emitter of the transistor 201 is coupled to the ground, the transistor 201 is turned on at this time, and since the gate of the field effect transistor 202 is coupled to the collector of the transistor 201, the transistor 201 is turned on so that the field effect transistor 202 is turned on. The field effect transistor 202 is turned on so that the electrical signal of the power supply 30 can be output to the air conditioner outdoor unit assembly 40 through the field effect transistor 202, so that the power supply 30 supplies power to the air conditioner outdoor unit assembly 40, thereby controlling the operation of the air conditioner outdoor unit assembly 40 through the adjustment device 50. Further, as Figure 2 As shown, the switch assembly 20 is provided with a first port 101, a second port 102 and a third port 103, the first port 101 is coupled to the base of the transistor 201, and the control device 10 is coupled to the first port 101. The second port 102 is coupled to the source of the field effect transistor 202, and the other end is coupled to the power supply 30, and the third port 103 is coupled to the drain of the field effect transistor 202, and the other end is coupled to the air conditioner outdoor unit assembly 40, that is, the control device 10 outputs the electrical signal to the base of the transistor 201 through the first port 101, so that the transistor 201 is turned on and the field effect transistor 202 is turned on, and the power supply 30 outputs the electrical signal to the field effect transistor 202 through the second port 102, and outputs it to the air conditioner outdoor unit assembly 40 through the third port 103.

[0031] In an optional embodiment, the switch assembly 20 further includes: a first protection circuit 203 and a second protection circuit 204, wherein one end of the first protection circuit 203 is coupled to the base of the transistor 201, and the other end is grounded. One end of the second protection circuit 204 is connected to the collector of the transistor 201, and the other end is connected to the power supply 30. The first protection circuit 203 may be a capacitor-resistor circuit, i.e., a capacitor-resistor parallel circuit, which may reduce the voltage and filter the electrical signal output by the control device 10, or may be set to other reduction and filtering circuits, which are not specifically limited in this application. That is, one end of the first protection circuit 203 is connected to the output end of the control device 10, and the other end is connected to the emitter of the transistor 201, so as to reduce the voltage and filter the electrical signal output by the control device 10, thereby protecting the transistor 201. One end of the second protection circuit 204 is connected to the collector of the transistor 201, and the other end is connected to the power supply 30. After the control device 10 outputs a low-level signal or cuts off the output of the electrical signal, the transistor 201 is disconnected and can be discharged through the second protection circuit 204, thereby protecting the transistor 201. Specifically, as Figure 2 As shown, the second protection circuit 204 may include a diode 208, the anode of the diode 208 is coupled to the collector of the transistor 201, and the cathode of the diode 208 is connected to the power supply 30, so that the transistor 201 is discharged through the diode 208 after being turned off, thereby providing discharge protection for the transistor 201.

[0032] In a specific application scenario, the control device 10 outputs a low-level signal or a cutoff signal output, the base of the transistor 201 has no signal input or receives a low-level signal, and the transistor 201 is in a cut-off state. Since the collector of the transistor 201 is connected to the gate of the field effect transistor 202, the transistor 201 is cut off, so that the field effect transistor 202 is cut off, so that the electrical signal of the power supply 30 cannot be output to the air-conditioning outdoor unit assembly 40 through the field effect transistor 202, that is, when parking, the control device 10 controls the switch assembly 20 to disconnect, so that the power supply 30 is disconnected from the air-conditioning outdoor unit assembly 40, preventing the air-conditioning outdoor unit assembly 40 from continuously consuming the electrical energy of the power supply 30.

[0033] In an optional embodiment, the switch assembly 20 further includes a third protection circuit 205, the third protection circuit 205 includes a first capacitor 206 and a second capacitor 207, the common end of the first capacitor 206 and the second capacitor 207 is coupled to the collector of the transistor 201, the other end of the first capacitor 206 is coupled to the source of the field effect tube 202, and the other end of the second capacitor 207 is coupled to the drain of the field effect tube 202. The third protection circuit 205 can play a damping role to prevent the field effect tube 202 from being damaged due to too fast switching action when the control device 10 controls the switch assembly 20 to be turned on or off, and can make the working power supply 30 of the field effect tube 202 more balanced, effectively preventing the air conditioner outdoor unit assembly 40 from being damaged by excessive voltage. That is, the third protection circuit 205 can protect the field effect tube 202 and ensure the working voltage of the air conditioner outdoor unit assembly 40. In other embodiments, the third protection circuit 205 can also be set as a filter circuit to make the current more stable, which is not specifically limited in this application.

[0034] In an optional embodiment, the control circuit of the air conditioner outdoor unit assembly 40 further includes a drive assembly 60, which is communicatively connected with the adjustment device 50 and coupled with the switch assembly 20, wherein the drive assembly 60 can be specifically configured as a digital signal processor for processing the digital signal of the adjustment device 50, so as to facilitate driving the air conditioner outdoor unit assembly 40. Specifically, the adjustment device 50 is communicatively connected with the drive assembly 60, so that the enable signal of the adjustment device 50 can be transmitted to the drive assembly 60, and the drive assembly 60 controls the operation of the air conditioner outdoor unit assembly 40 after receiving the enable signal of the adjustment device 50. In this embodiment, a drive circuit 70 is connected to the drive assembly 60, and the drive circuit 70 is coupled with the switch assembly 20 and the air conditioner outdoor unit assembly 40. After the driving component 60 outputs the enable signal, the driving component 60 receives the enable signal, so that the driving circuit 70 drives the air conditioner outdoor unit component 40 to work, wherein the driving component 60 is coupled to the switch component 20, and the control device 10 inputs a high-level signal, so that the transistor 201 and the field effect transistor 202 are turned on, so that the current of the power supply 30 flows through the switch component 20 and supplies power to the driving circuit 70, and the driving component 60 is coupled to the switch component 20, that is, the switch component 20 is respectively connected to the driving component 60 and the driving circuit 70, so that the control device 10 can control the on and off of the driving component 60 and the driving circuit 70, and when parking, it can effectively prevent the driving component 60 from being directly connected to the power supply 30, so that the driving component 60 continues to consume the electrical energy of the power supply 30, resulting in energy consumption.

[0035] In an optional embodiment, the switch component 20 further includes a step-down conversion circuit 209, one end of which is coupled to the drain of the field effect tube 202, and the other end of which is respectively coupled to the drive component 60 and the drive circuit 70. The step-down conversion circuit 209 balances the current of the power supply 30 and maintains the voltage unchanged, thereby effectively ensuring the working stability of the drive component 60 when the power supply 30 outputs an electrical signal.

[0036] In an optional embodiment, the control circuit of the air-conditioning outdoor unit assembly 40 also includes an indoor unit, and the indoor unit and the air-conditioning outdoor unit assembly 40 are powered separately. That is, the air-conditioning outdoor unit assembly 40 and the indoor unit are powered separately, so that when the vehicle is parked, the air-conditioning outdoor unit assembly 40 does not consume energy while the indoor unit is working. For example, the indoor unit can continuously cool or heat the interior of the vehicle, and the air-conditioning outdoor unit assembly 40 can be turned on when necessary. In the event of a failure of some air-conditioning outdoor unit assemblies 40, the indoor unit can still operate independently. In other embodiments, the indoor unit and the air-conditioning outdoor unit assembly 40 can be powered at the same time to prevent the indoor unit from continuously working while the air-conditioning outdoor unit assembly 40 does not work, resulting in damage to the indoor unit. This application does not make specific limitations here.

[0037] In a specific application scenario, when parking, the control device 10 outputs a low-level signal or a cutoff signal output, so that the transistor 201 is disconnected to control the field effect tube 202 to be disconnected, thereby disconnecting the power supply 30 from the drive component 60, the drive circuit 70, and the air conditioner outdoor unit component 40, thereby preventing the air conditioner outdoor unit component 40 and the drive component 60 from continuously consuming the power supply 30 and causing unnecessary energy consumption. When the air conditioner outdoor unit component 40 needs to be turned on, the control device 10 outputs a high-level signal, and after the base of the transistor 201 receives the high-level signal, the base of the transistor 201 is connected to the ground, so that the field effect tube 202 is turned on, so that the electrical signal of the power supply 30 can be output to the air conditioner outdoor unit component 40, the drive component 60 and the drive circuit 70 via the field effect tube 202. On this basis, the adjustment device 50 outputs an enable signal, the drive component 60 receives the enable signal and controls the drive circuit 70 to work, so that the air conditioner outdoor unit component 40 starts to work.

[0038] In the above manner, the present application sets a switch assembly 20 between the power supply 30 and the air conditioner outdoor unit assembly 40, and couples the control device 10 to the switch assembly 20. The control device 10 outputs a low-level signal or a cut-off signal output to control the switch assembly 20 to disconnect, and controls the power supply 30 to disconnect from the air conditioner outdoor unit assembly 40, so that the power supply 30 cannot supply power to the air conditioner outdoor unit assembly 40, and effectively prevents the air conditioner outdoor unit assembly 40 from continuously consuming the power of the power supply 30 due to the connection with the power supply 30. By setting a transistor 201 and a field effect transistor 202, the control device 10 is coupled to the base of the transistor 201, and the field effect transistor 202 is set between the power supply 30 and the air conditioner outdoor unit assembly 40, the control device 10 can control the on-off of the transistor 201, and the on-off of the transistor 201 controls the on-off of the field effect transistor 202, thereby controlling the on-off of the power supply 30 and the control device 10. By setting the first protection circuit 203 and the second protection circuit 204, the first protection circuit 203 can reduce the voltage and filter the electric signal output by the control device 10. After the control device 10 cuts off the output of the electric signal, the transistor 201 can be discharged through the second protection circuit 204, thereby protecting the transistor 201. By setting the third protection circuit 205, when the control device 10 controls the switch component 20 to turn on or off, the field effect tube 202 can be prevented from being damaged by too fast a switching action, and the working power supply 30 of the field effect tube 202 can be made more balanced, effectively preventing the air conditioner outdoor unit component 40 from being damaged by excessive voltage. By setting the adjustment device 50, an enable signal can be sent to make the air conditioner outdoor unit component 40 work. By setting the drive component 60 and the drive circuit 70, the enable signal of the adjustment device 50 can be received, so that the drive component 60 controls the drive circuit 70 to drive the air conditioner outdoor unit component 40 to start working. By coupling the step-down conversion circuit 209 between the driving component 60 and the driving circuit 70 , the current of the power source 30 can be balanced, the voltage can be maintained unchanged, and the working stability of the driving component 60 can be ensured.

[0039] See also Figure 4 , Figure 4 1 is a flow chart of an embodiment of the control method of the air conditioner outdoor unit of the present application. It should be noted that if there is substantially the same result, the method of the present invention is not limited to Figure 4 The process sequence shown is limited. Figure 4 As shown, the method comprises the following steps:

[0040] S11: the control device 10 inputs a low level signal to the switch component 20;

[0041] When the air conditioner is on standby, that is, when the vehicle is parked, the power supply 30 needs to be disconnected from the air conditioner outdoor unit 40, and the control device 10 outputs a low level signal. In other embodiments, the control device 10 may also cut off the signal output, which is not specifically limited in this application.

[0042] S12 : The switch assembly 20 receives a low-level signal and disconnects at least part of the connection between the power source 30 and the air-conditioning outdoor unit assembly 40 , so that the power source 30 cannot supply power to the air-conditioning outdoor unit assembly 40 .

[0043] Specifically, the output end of the control device 10 is coupled to the base of the transistor 201, that is, the low-level signal output by the control device 10 is transmitted to the transistor 201, and the transistor 201 is cut off so that the field effect transistor 202 is cut off, disconnecting the connection between the power supply 30 and the air-conditioning outdoor unit component 40, so that the power supply 30 cannot supply power to the air-conditioning outdoor unit component 40.

[0044] In an optional embodiment, when the air conditioner is on standby, the control device 10 can output a low-level signal or a cutoff signal output, and the transistor 201 receives the low-level signal. The transistor 201 is cut off, causing the field effect transistor 202 to be cut off, thereby disconnecting the power supply 30 from the drive component 60, the drive circuit 70, and the air conditioner outdoor unit component 40, effectively preventing the drive component 60 and the air conditioner outdoor unit component 40 from continuously consuming the electrical energy of the power supply 30, thereby increasing energy consumption.

[0045] See also Figure 5 , Figure 5 FIG. 1 is a flow chart of another embodiment of the control method of the air conditioner outdoor unit of the present invention. It should be noted that if there is substantially the same result, the method of the present invention is not limited to the control method of the air conditioner outdoor unit of the present invention. Figure 5 The process sequence shown is limited. Figure 5 As shown, the method comprises the following steps:

[0046] S21: the control device 10 inputs a high level signal to the switch component 20;

[0047] When the air conditioner needs to be turned on, the air conditioner outdoor unit component 40 needs to be connected to the power supply 30 so that the power supply 30 supplies power to the air conditioner outdoor unit component 40, and the control device 10 outputs a high-level signal. The voltage value range of the high-level signal is greater than the voltage of the low-level signal. The control method of the air conditioner outdoor unit is executed by the air conditioner outdoor unit control circuit.

[0048] S22 : the switch assembly 20 receives the high level signal, and switches on the power supply 30 and the air conditioner outdoor unit assembly 40 , so that the power supply 30 supplies power to the air conditioner outdoor unit assembly 40 .

[0049] In this embodiment, the control device 10 outputs a high-level signal, and the transistor 201 receives the high-level signal so that the base and emitter of the transistor 201 are turned on. Since the gate of the field effect transistor 202 is coupled to the collector of the transistor 201, the transistor 201 is turned on so that the field effect transistor 202 is turned on to connect with the ground. The field effect transistor 202 is turned on so that the power supply 30 is turned on with the drive component 60, the drive circuit 70 and the air-conditioning outdoor unit component 40. On this basis, the user can use the adjustment device 50 to output different enable signals.
