In addition, the working voltage of the notebook computer is 20V, specifically, when the user connects the power line of the notebook computer with the power output interface 60 of the outdoor power supply device and presses the ac trigger button; the main control component 20 controls the dc voltage converting circuit 30 to convert the voltage received by the power source terminal and output a dc voltage; it should be understood that, when the user presses the dc trigger button, the switch circuit 40 is in a conducting state, and the inverter circuit 50 is in a state of stopping working, the voltage accessed by the power end is not input to the inverter circuit 50 and is converted into ac, that is, the dc output by the dc voltage converting circuit 30 only passes through the switch circuit 40, and the dc voltage is output through the power output interface 60 to provide power for the notebook computer.
The utility model provides an outdoor power supply device capable of switching direct current output and alternating current output, which comprises a power output interface 60, a main control component 20, a trigger component 10, a switch circuit 40, a direct current voltage conversion circuit 30 and an inverter circuit 50; the main control component 20 is configured to control the switch circuit 40 to be in a disconnected state when receiving the first trigger signal, control the dc voltage converting circuit 30 to convert the voltage of the power source terminal and output a first dc voltage, and control the inverter circuit 50 to convert the first dc voltage into a first ac voltage and output the first ac voltage to the power source output interface 60; the main control component 20 is further configured to control the switch circuit 40 to be in a conducting state when receiving the second trigger signal, control the dc-to-dc voltage converting circuit 30 to convert the voltage received by the power source terminal, and then output a second dc voltage through the switch circuit 40 and the power output interface 60, and control the inverter circuit 50 to stop working. The utility model discloses utilize main control assembly 20 control direct voltage converting circuit 30 and inverter circuit 50 to realize alternating current and direct current's switching, satisfy the user to the power consumption demand of direct current and alternating current simultaneously.
In this embodiment, referring to fig. 2, the outdoor power supply apparatus capable of switching between dc output and ac output further includes:
a current limiting circuit 70;
a first input end of the current limiting circuit 70 is connected to the output end of the switch circuit 40, a second input end of the current limiting circuit 70 is connected to the output end of the inverter circuit 50, and an output end of the current limiting circuit 70 is connected to the power output port;
the current limiting circuit 70 is configured to cut off the output of the first ac voltage to the power output interface 60 when a voltage value corresponding to the first ac voltage output by the inverter circuit 50 exceeds a first preset voltage value; and cutting off the output of the second dc voltage to the power output interface 60 when the voltage value corresponding to the second dc voltage output by the dc voltage conversion circuit 30 exceeds a second preset voltage value.
It will be appreciated that a current limiting circuit 70 is provided between the switching circuit 40 and the power output interface 60 to prevent damage to the power output interface 60 from overcurrent. In this embodiment, the current limiting circuit 70 includes a current limiting resistor, and the current limiting resistor is formed by serially connecting resistors in the circuit to limit the magnitude of the current of the branch circuit, so as to prevent the current from being too large to burn out the serially connected components. Meanwhile, the current limiting resistor can also play a role in voltage division.
Specifically, when the current value output by the power output interface 60 passes through the current limiting resistor and exceeds the preset current value, the current limiting resistor takes a current limiting measure on the path between the switch circuit 40 and the power output interface 60 or on the path between the inverter circuit 50 and the power output interface 60 to ensure that the output current value is in the safe value range. For example, a user connects a charging wire connected to a battery of an electric vehicle to the power output interface 60 of the outdoor power supply device, the operating voltage of the battery of the electric vehicle is 12V, and the current of the corresponding battery is 35A. When the current output by the dc voltage converting circuit 30 through the switch circuit 40 exceeds 35A, the current limiting resistor limits the current in the path between the switch circuit 40 and the power output interface 60, so that the current output by the power output interface 60 is maintained at the value of 35A, thereby preventing the battery of the electric vehicle from being damaged by the overcurrent.
In another embodiment, refer to fig. 3;

Specifically, when a user needs to charge the charging heads of multiple mobile phones at the same time, the charging heads of the multiple mobile phones are connected to the multiple power output interfaces 60, and the number of the current limiting circuits 70 arranged inside the charging heads corresponds to the number of the multiple power output interfaces 60, so as to protect each power output interface 60 from being damaged by an overcurrent.
In another embodiment, referring to fig. 3, a second switch circuit 80 is disposed between each of the current limiting circuits 70 and the switch circuit 40; the controlled ends of the second switch circuits 80 are respectively electrically connected with the main control assembly 20, and the second switch circuits 80 are in a normally-off state;

It will be appreciated that in the case where only one interface is required, the other interfaces are also live, assuming that accidental touching of the other power output interface 60 by a user while using a single interface would result in the risk of an electric shock. In order to prevent the user from generating the danger of touching by mistake, referring to fig. 3, in another embodiment, a plurality of second switch circuits 80 are added, and the controlled end of each second switch circuit 80 is electrically connected to the main control assembly 20. It should be understood that the plurality of second switch circuits 80 are in the off state for a long time, that is, the voltage cannot be output to the input terminal of the second switch circuit 80, so that each second switch circuit 80 cannot output the voltage to the power output interface 60, and the user is prevented from getting an electric shock due to mistaken electric shock to the power output interface 60.
In addition, the triggering component 10 is also implemented by using a switch button, when a user needs to use a plurality of power output interfaces 60, the user needs to press the switch button corresponding to the power output interface 60 first, the switch button outputs a third triggering signal, the triggering main control component 20 controls the second switch circuit 80 corresponding to the switch button to be in a conducting state, and at this time, the voltage can be output to the input end of the second switch circuit 80, so that the second switch circuit 80 can output the voltage to the power output interface 60.
It will be appreciated that a user may utilize multiple power output interfaces 60 simultaneously to power different devices by simply pressing the dc button or the ac button. And at least one power output interface 60 of the plurality of power output interfaces 60 has a different interface type from the other power output interfaces 60. For example, outdoor power supply unit has three power output interface 60, and its three power output interface 60's Type is three hole sockets, USBType-B, USBType-C respectively, and large-scale fan that falls to the ground can be connected to three hole sockets, and the smart mobile phone can be connected to USBType-C. The outdoor power supply apparatus in this embodiment provides a user with a plurality of interface types of the power output interface 60, and the user can simultaneously supply power to a plurality of different types of devices.
