[0049] A portable air conditioner provided by an embodiment of the present utility model. Figure 1 Fig. shows a portable air conditioner 1 in an embodiment of the present utility model. The portable air conditioner can be used in outdoor activities such as camping, is simple and convenient to use, and is convenient for users to carry. The portable air conditioner 1 includes an air conditioner main unit (10) and a power supply device (20) operably electrically connected to the air conditioner main unit (10).

[0050] As Figure 2 and Figure 3 shown, the air conditioner main unit (10) includes a refrigeration unit (12), a control module (not shown) electrically connected to the refrigeration unit (12), and a first interface (1121c).

[0051] Specifically, the air conditioner main unit 10 includes a first housing 11, a refrigeration unit 12, and a control module. The refrigeration unit 12 and the control module are disposed inside the first housing 11.

[0052] As Figure 3 shown, in some embodiments, the control module includes a main control unit, which is also disposed inside the first housing 11 and electrically connected to the refrigeration unit 12 to control the operation of the refrigeration unit 12. The first housing 11 includes a base 112. The refrigeration unit 12 is disposed on the base 112.

[0053] As Figure 5 shown, the power supply device includes a battery unit (22), a main control component (not shown) electrically connected to the battery unit (22), and a third interface (231).

[0054] Referring together to Figure 4 and Figure 5 , the power supply device 20 includes a second housing 21, a battery unit 22, and a main control component.

[0055] The battery unit 22 and the main control component are both disposed inside the second housing 21, and the main control component is also electrically connected to the battery unit 22 together to control the output of the electric energy of the battery unit 22, or communicate with the air conditioner main unit 10 or other power supply devices 20.

[0056] In some embodiments, as Figure 4As shown, the battery unit 22 further includes a cable 23. One end of the cable 23 extends deep into the second housing 21 and is electrically connected to the main control component. The other end of the cable 23 extends out of the second housing 21 and is used to be electrically connected to the air conditioner main unit 10 to supply power to the air conditioner main unit 10 and communicate with the air conditioner main unit 10, or the other end of the cable 23 is also connected in series with other power supply devices 20.

[0057] The first interface (1121c) is detachably connected to the third interface (231).

[0058] When the first interface (1121c) is connected to the third interface (231), the battery unit, under the control of the main control component, supplies power to the control module and the refrigeration unit (12) through the third interface (231) and the first interface (1121c).

[0059] Specifically, the base 112 is provided with a first interface 1121c for electrically connecting to the power supply device 20 to supply power to the air conditioner main unit 10 and communicate with the air conditioner main unit 10.

[0060] In this embodiment, by constructing a portable air conditioner with a power supply device, the air conditioner can be used even without an external power supply and has a longer usage time. At the same time, the detachable connection between the air conditioner main unit and the power supply device enables the air conditioner main unit and the power supply device to be carried separately, further improving the flexibility of the portable air conditioner.

[0061] In a feasible embodiment, the first interface (1121c) includes a first power terminal and a first signal terminal. The first power terminal is electrically connected to the refrigeration unit (12), and the first signal terminal is electrically connected to the control module.

[0062] The third interface (231) includes a third power terminal and a third signal terminal.

[0063] When the first interface (1121c) is connected to the third interface (231), the first power terminal is connected to the third power terminal; the first signal terminal is connected to the third signal terminal.

[0064] Specifically, the terminal can also be referred to as a terminal. By integrating power terminals and signal terminals in the interface, in addition to being able to provide power through the interface, communication can also be carried out through the interface.

[0065] Again, Figure 2As shown, in one embodiment, a first interface 1121c is provided on the base 112 for electrically connecting to the power supply device 20 to supply power to the air conditioner main unit 10 and communicate with the air conditioner main unit 10. The first interface 1121c includes a custom first power terminal and a custom first signal terminal. The first power terminal is electrically connected to the refrigeration unit 12, and the first signal terminal is electrically connected to the main control unit. Specifically, the number of the first power transmission terminals is two, and the number of the first signal terminals is four. And in some embodiments, both the first power terminal and the first signal terminal can adopt pin pins, that is, in this embodiment, the first interface 1121c is an interface with six custom pin pins (as Figure 8 shown), which can transmit electrical energy and control signals simultaneously on one side.

[0066] In this embodiment, the power supply device supplies power to the air conditioner main unit through the third power terminal, and the air conditioner main unit receives the electrical energy provided by the power supply device through the first power terminal. The air conditioner main unit receives the status information of the power supply device provided by the power supply device through the third signal terminal through the first signal terminal.

[0067] In a feasible embodiment, as Figure 6 shown, the power supply device further includes a second interface (2125) for accessing a third-party power supply.

[0068] The second interface (2125) includes a second power terminal and a second signal terminal. The second power terminal is respectively electrically connected to the battery unit (22) and the main control component, and the second signal terminal is electrically connected to the main control component.

[0069] In some embodiments, the power supply device 20 supports charging from external power sources such as solar energy, adapters / chargers, and vehicle cigarette lighters.

[0070] Referring together to Figure 4 , a second interface 2125, a power switch 2126, and a power quantity display are further provided on the lower housing 212. The second interface 2125 includes a custom second power terminal and a custom second signal terminal. The second power terminal is respectively electrically connected to the battery unit 22 and the main control component, and the second signal terminal is electrically connected to the main control component. Specifically, the number of the second power terminals is two, and the number of the second signal terminals is four. And in some embodiments, both the second power terminal and the second signal terminal can adopt pin pins. The power switch 2126 is used to control the turning on and off of the power supply device 20. The power quantity display is used to display the remaining power of the battery unit 22.

[0071] In some embodiments, the power switch 2126 is an AC power switch. Long pressing it realizes the on and off functions, and it can automatically identify and turn off without load within thirty minutes. Short pressing it realizes the turning on and off of the power quantity display.

[0072] In some embodiments, such as Figure 10 shown, the power display shows the remaining power through a power segment display tube.

[0073] In this embodiment, the battery unit 22 includes but is not limited to fifty-six battery elements, and can be arranged in a rectangular shape in groups of four, with each group arranged side by side. The total capacity can be but is not limited to 5000 mAh, the total electric energy can be but is not limited to 960 Wh, the full charge voltage can be but is not limited to 58.8 v, and the shutdown voltage can be but is not limited to 40.6 v. It can be understood that the number of battery elements can be adjusted as needed.

[0074] It should be noted that the charging input (i.e., the second interface 2125) of the battery unit 22 is current-limited to 10 A and power-limited to 500 W, supports charging with a 500 W / 50 V adapter, supports 11 - 75 v MPPT step-up and step-down charging or solar charging, and supports 11 v - 13 v cigarette lighter charging. And the second interface 2125 has reverse connection protection and overcharging protection functions. The output of the battery unit 22 is current-limited to 25 A and has short-circuit protection and under-voltage protection.

[0075] In some embodiments, a third interface 231 is provided at the free end of the cable 23. The third interface 231 includes a custom third power terminal and a custom third signal terminal. The third power terminal is electrically connected to the battery unit 22 and the main control component respectively, and the third signal terminal is electrically connected to the main control component. Specifically, the number of the third power terminals is two, and the number of the third signal terminals is four. And in some embodiments, both the third power terminal and the third signal terminal can adopt pin pins, that is, in this embodiment, the third interface 231 is an interface with six custom pin pins (such as Figure 9 shown), and the third interface 231 can be adapted to the first interface 1121c and the second interface 2125 respectively to realize the transmission of electric energy and control signals.

[0076] Figure 7 shows the circuit principle block diagram of the power supply device 20. From Figure 7 it can be seen that the circuit part of the power supply device 20 can include an input port, a DC-DC step-up and step-down controller, a battery unit 22, an output controller, an air conditioner power supply interface, a DC and PD fast charging power supply interface, a microcontroller, a battery pack cascaded upstream communication interface, and a battery pack cascaded downstream communication interface.

[0077] Among them, the input port (i.e., the second interface 2125) is used for power input. The DC-DC buck-boost controller is electrically connected to the input port to boost or buck the voltage of the input power supply to charge the battery unit 22. The battery unit 22 is also electrically connected to the output controller, which is used to control the external power supply output of the battery unit 22. The output controller is also electrically connected to the air conditioner power supply interface and the DC and PD fast charging power supply interface respectively. The air conditioner power supply interface is used to be electrically connected to the first interface 1121c through the cable 23 to realize the power supply function of the air conditioner. The DC and PD fast charging power supply interface includes a 12V 150W DC output, a PD 100W TypeC, and a QC3.0 18W TypeA USB output.

[0078] In addition, the DC-DC buck-boost controller is also electrically connected to the microcontroller, which is used to control the DC-DC buck-boost controller, as well as to control the external output and external communication connection functions of the battery unit 22. The microcontroller is also electrically connected to the battery pack cascade upstream communication interface and the battery pack cascade downstream communication interface for corresponding connection with the four first signal terminals of the first interface 1121c for transmitting protocol signals. Similarly, the air conditioner power supply interface is used to be electrically connected to two first power terminals in the first interface 1121c for transmitting large current.

[0079] In some embodiments, the power supply device 20 may further include, but is not limited to, one TypeC 100W output, one USB 18W QC3.0 output, and one regulated 12V 150W Anderson output.

[0080] In some embodiments, the power supply device 20 may further have functions such as overcharge / overdischarge protection, output short-circuit protection, input reverse connection protection, low-temperature protection, and high-temperature protection.

[0081] During the specific use process, when the power supply device 20 is in an inactive state, after connecting the cable 23 of the power supply device 20 to the first interface 1121c, the power supply device 20 can be automatically activated without pressing the power switch 2126.

[0082] In some embodiments, whether the power supply device 20 is manually or automatically activated to turn on the output of the battery unit 22, if the air conditioner host 10 is not detected within thirty minutes, the output will be automatically turned off.

[0083] In a feasible embodiment, the third-party power supply includes a power system and / or a power supply device.

[0084] Specifically, the second interface can be connected to the public power grid through a connecting wire to provide power for the power supply device.

[0085] The second interface can also be used to connect to the third interface of another power supply device to charge this power supply device through the third interface of the other power supply device, or to supply power to the air conditioner through this power supply device. The other power supply device can also transmit the battery information of the other power supply device to the third signal terminal of this power supply device through the second signal terminal. Thus, this power supply device, or this power supply device and the air conditioner main unit, can obtain the status of the other power supply device to prevent sudden power loss.

[0086] In a feasible embodiment, the number of power supply devices (20) is at least two. At least two power supply devices are connected in series, and the third interface (231) of the subsequent power supply device is connected to the second interface (2125) of the previous power supply device. The third interface (231) of the first power supply device is connected to the first interface (1121c).

[0087] Specifically, when there are two or more of the at least one power supply device 20, they can also be conveniently connected in series to jointly supply power to the air conditioner main unit 10. In this way, two or more power supply devices 20 can significantly increase the battery life of the air conditioner main unit 10.

[0088] During the specific use process, multiple power supply devices 20 can be connected and arranged. The third interface 231 of the cable 23 of one power supply device 20 is electrically connected to the first interface 1121c on the base 112 of the air conditioner, and the third interfaces 231 of the cables 23 of the remaining power supply devices 20 are sequentially connected to the second interfaces 2125 of the adjacent power supply devices 20 to achieve the series connection of multiple power supply devices 20. It should be understood that due to the presence of the second interface 2125, this power supply device 20 can also be connected to an external power supply while supplying power to charge the battery unit 22 of the power supply device 20.

[0089] When multiple power supply devices 20 are sequentially connected to supply power to the air conditioner main unit 10, this power supply device 20 supports cascaded power supply. The power supply device 20 closest to the air conditioner main unit 10 is preferentially used for power supply, and the other power supply devices 20 are in an inactive state until the power supply device 20 closest to the air conditioner main unit 10 runs out of power, then the power supply device 20 second closest to the air conditioner main unit 10 is activated, and so on. When no external charging device is connected, the power supply devices 20 do not charge each other.

[0090] It should be noted that the above "closest to the air conditioner main unit 10" and "second closest to the air conditioner main unit 10" refer to "directly connected to the first interface 1121c" and "indirectly connected to the first interface 1121c through one power supply device 20".

[0091] When multiple power supply devices 20 need to be charged, the power supply devices 20 support cascaded charging, that is, they preferentially charge the power supply devices 20 in the discharging state. When all the power supply devices 20 are in the inactive state, they preferentially charge the power supply device 20 farthest from the external power supply.

[0092] It should be understood that the above "farthest from the external power supply" means "electrically connected to the external power supply through the remaining power supply devices 20".

[0093] In some embodiments, during cascaded charging, if the activated power supply device 20 was automatically shut down before, it can be automatically turned on during the cascaded charging process.

[0094] In some embodiments, the power supply device 20 also has the function of charging while discharging. When a single power supply device 20 charges while discharging, if the load power is greater than the charging power, the insufficient part is supplemented by the power supply device 20; if the load power is less than the charging power, the excess part is used to charge the power supply device 20.

[0095] When multiple power supply devices 20 are connected in sequence and charge while discharging, charging and power supply are both preferentially carried out through the power supply device 20 closest to the air-conditioning host 10. The external power supply charges the power supply device 20 closest to the air-conditioning host 10, and at the same time, the power supply device 20 closest to the air-conditioning host 10 charges the air-conditioning host 10 until the power supply device 20 closest to the air-conditioning host 10 runs out of power (load power is greater than charging power) or is fully charged (load power is less than charging power), and then the power supply device 20 second closest to the air-conditioning host 10 is activated for charging, and so on.

[0096] Refer to together Figure 8 , the third interface 231, the second interface 2125, and the first interface 1121c all include two power terminals and four signal terminals. Among them, the two power terminals are used to transmit large current, and the other four signal terminals are used to transmit protocol signals. Specifically, among the four signal terminals, two signal terminals can be used to transmit 485 serial communication signals, and one of the other two signal terminals is used to transmit battery cascading detection signals, and the other is used for air-conditioning detection signals. In this way, both power energy and control signals can be transmitted between the power supply device 20 and the air-conditioning host 10 and between the power supply device 20 and other power supply devices 20.

[0097] In a feasible embodiment, the power terminals of the first interface (1121c) and the second interface (2125) are pins, and the signal terminals are jacks. The power terminals of the third interface (231) are jacks, and the signal terminals are pins.

[0098] Alternatively, the power terminals of the first interface (1121c) and the second interface (2125) are jacks, and the signal terminals are pins; the power terminals of the third interface (231) are pins, and the signal terminals are jacks.

[0099] Setting both pins and jacks on the interface can improve the mechanical strength of the interface, enhance the ability to resist external tensile forces and impacts, and reduce the risk of accidental disconnection. At the same time, it also increases the stability and firmness of the connection, reducing safety issues caused by poor contact.

[0100] In a feasible embodiment, the diameters of the power terminals of the first interface (1121c), the second interface (2125), and the third interface (231) are larger than the diameters of the signal terminals.

[0101] Due to their larger diameters, the power terminals can carry a higher current load and provide sufficient current for the air-conditioning main unit. At the same time, due to their larger sizes, the power terminals have higher mechanical strength, can better resist external tensile forces and impacts, and help prevent accidental disconnection and ensure circuit stability. As signal transmission components, the signal terminals only need to provide an appropriate current passing rate to meet the requirements. Therefore, the signal terminals have lower manufacturing costs due to their smaller sizes and lower material requirements. At the same time, due to the smaller diameters of the signal terminals, the resistance is smaller, which can reduce signal loss during signal transmission to ensure the accuracy of signal transmission.

[0102] The signal terminals are distributed in a herringbone pattern. The power terminals are distributed on the left and right sides of the signal terminals.

[0103] Arranging the signal terminals in a herringbone pattern can prevent incorrect connection and avoid equipment damage or safety accidents caused by improper connection. At the same time, the herringbone pattern provides an upward supporting force, strengthening the mechanical strength of the connection part.

[0104] In some embodiments, the second interface 2125 is an interface with six custom pin pins (as Figure 8 shown), and it can simultaneously transmit electrical energy and control signals on one side. It can be used to connect to an external power supply to charge the battery unit 22.

[0105] In some embodiments, the third interface 231 is an interface with six custom pin pins (as Figure 9 shown), and the third interface 231 can be adapted to the first interface 1121c and the second interface 2125 respectively to enable the transmission of electrical energy and control signals.

[0106] In a feasible embodiment, the air-conditioning main unit further includes a power supply communication module for transmitting the status information of the power supply device received by the first interface to the control module; the power supply communication module is connected to the control module and the first interface.

[0107] The main control component obtains the status information of the power supply device and transmits it to the third interface, and the third interface transmits the status information of the power supply device to the first interface.

[0108] The control module is used to receive and process the power supply information sent by the power supply communication module.

[0109] Specifically, through a dedicated communication link, the risk of data loss during transmission is reduced. By effectively managing the power supply information, system failures caused by unstable power supply are reduced.

[0110] Furthermore, the air conditioner main unit is connected to the power supply device through the third interface after the serial port is converted to 485.

[0111] The serial port setting parameters are as follows:

[0112] Baud rate: 9600;

[0113] Start bit: 1 bit low level;

[0114] Data bit: 8 bits;

[0115] Parity bit: None;

[0116] Stop bit: 1 bit high level;

[0117] Idle bit: High level;

[0118] Transmission data format: Transmit from the low bit;
