DETAILED DESCRIPTION

[0037] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0038] The utility model provides a power adapter compatible with multiple output powers, so as to solve the problem that the power adapter in the prior art can only output a single power, thereby limiting the scope of application and causing many inconveniences in actual use.

[0039] For ease of understanding, the specific process in the embodiment of this application is described below. Figures 1 to 5 , a power adapter compatible with multiple output powers in an embodiment of the present application includes a power frame 1, a socket spring 2, an AC power cord 3, a split PD power supply 4, an output distribution module 5 and an output port 6; the power frame 1 is composed of a front cover 10 and a rear cover 11, and the front cover 10 and the rear cover 11 constitute an accommodating space; multiple split PD power supplies 4 are inserted into the socket spring 2 through the rear cover 11, and multiple socket springs 2 are arranged in parallel in the accommodating space; the AC power cord 3 is connected to the socket spring 2; the output distribution module 5 is arranged in the accommodating space, and the output distribution module 5 is respectively connected to the AC power cord 3 and the split PD power supply 4; the output port 6 is arranged outside the rear cover 11, the output port 6 is communicated with the output distribution module 5, and the number of the output ports 6 corresponds to the split PD power supply 4.

[0040] The power adapter of the present invention is compatible with multiple output powers. The output distribution module 5 can distribute the corresponding output power to the electronic device connected to the output port 6 according to the number of split-type PD power supplies 4 and the needs of the electronic device externally connected to the output port 6, thereby meeting the needs of electronic devices with different output powers and adapting to a wide range of scenarios.

[0041] based on Figures 4 and 5 Furthermore, in this embodiment, there are four split-type PD power supplies 4, and the following description is based on four split-type PD power supplies 4. The split-type PD power supply 4 includes a plug that is plugged into the socket spring 2 and a PD terminal 40.

[0042] The output distribution module 5 is electrically connected to the split-type PD power supply 4 via the connection module 7. Specifically, the connection module 7 includes a second PCB board 60 and a plurality of second terminals 61 disposed on the second PCB board 60. The second PCB board 60 is disposed within the accommodating space, and the number of second PCB boards 60 corresponds to the number of split-type PD power supplies 4. The second terminals 61 are mounted on the second PCB board 60 and electrically connected to the PD terminals 40 on the corresponding split-type PD power supply 4.

[0043] In this way, when the four split-type PD power supplies 4 are inserted into the socket spring piece 2 , the four split-type PD power supplies 4 are electrically connected to the corresponding second terminals 61 through the PD terminals 40 .

[0044] based on Figures 4 and 5 Furthermore, in this embodiment, the output distribution module 5 includes a first PCB board 50 provided in the accommodating space; a chip module 51, a DC power module 52, a first terminal 53, a detection module 54, a boost switching module 55 and a parallel module 27 are mounted on the first PCB board 50; the DC power module 52 is connected to the chip module 51 to supply power from the AC power line 3 to the chip module 51, so that the chip module 51 can be in a working state.

[0045] The four first terminals 53 are installed in parallel on the first PCB board 50, and the four first terminals 53 are respectively connected to the second terminals 61, and the second terminals 61 are connected to the corresponding split-type PD power supply 4, thereby realizing the conduction between the split-type PD power supply 4 and the first terminal 53, and the first terminal 53 is also connected to the chip module 51.

[0046] The four detection modules 54 are also arranged relatively parallel on the first PCB board, and each of the detection modules 54 is connected to the first terminal 53 in a one-to-one correspondence. The four detection modules 54 are used to detect the number of corresponding split-type PD power supplies 4 and then feed back to the chip module 51, so that the chip module 51 can adjust the output power accordingly according to the number of split-type PD power supplies 4.

[0047] Each of the detection modules 54 is connected to the corresponding boost switching module 55, and the boost switching module 55 is connected to the chip module 51; multiple boost switching modules 55 are connected to the parallel module 27, and the parallel module 27 has multiple output ends, and each output end corresponds one-to-one to the corresponding output port 6.

[0048] Furthermore, the first PCB board 50 is inserted into the accommodating space through a guide rail, which is convenient for installation and use.

[0049] Furthermore, the split PD power supply 4 is also provided with an independent USB transmission port 41 , through which independent output can also be performed.

[0050] Furthermore, the back cover 11 is provided with an embedding cavity 20 for adapting the split-type PD power supply 4 to be embedded.

[0051] Furthermore, the frame 1 is also provided with an LED 12. When the AC power cord 3 is plugged into the mains, the LED 12 goes out. When the split PD power supply 4 is plugged into the frame, the LED 12 turns green. When one of the output ports 6 is plugged into an electronic device, the LED 12 turns from green to red, so that the status of the power adapter can be observed in real time.

[0052] The working principle of this power adapter is: when any number of split PD power supplies 4 are inserted, the split PD power supplies 4 are connected to the chip module 51 through the second terminal 61 and the first terminal 53, thereby sending voltage / current / CC signals to the detection module 54. At this time, the chip module 51 can detect the voltage / current through the detection module 54 to determine whether the boost switching module 55 should start the parallel module 27 and output through the output port 6 or directly output to the corresponding output port 6.

[0053] based on Figures 4 to 6 The following describes the working states when one to four split-type PD power supplies 4 are inserted. The output power of a single split-type PD power supply 4 is 60W.

[0054] Example 1:

[0055] If an output port 6 corresponding to the position of the split PD power supply 4 placed in the frame 1 is plugged into a DC connection line and connected to an electronic device, the corresponding LED 12 on the frame 1 will turn from green to red, and the electronic device will send a signal to the chip module 51 via the output port 6. After the chip module 51 makes a judgment based on the received signal, it will send the signal to the split PD power supply 4 via the second terminal 61. The split PD power supply 4 provides a relative voltage / current to the detection module 54 and the boost switching module 55 based on the received signal. At this time, the chip module 51 will decide whether to start the boost switching module 55 to boost the switching parallel module 27 and then output to the output port 6 or directly output to the output port 6 based on the voltage requirement of the electronic device.

[0056] Example 2:

[0057] If the output ports 6 of the two corresponding split PD power supplies 4 placed in the frame 1 are connected to two electronic devices with a DC connection line, the corresponding LED 12 on the frame 1 will turn from green to red, and the two electronic devices will send signals to the chip module 51 via the output port 6. After the chip module 51 makes a judgment based on the received signal, it will send the signal to the two split PD power supplies 4 via the second terminal 61. The two split PD power supplies 4 provide relative voltage / current to the detection module 54 and the boost switching module 55 based on the received signal. At this time, the chip module 51 will decide whether to start the boost switching module 55 to boost the switching parallel module 27 and then output to the output port 6 or directly output to the output port 6 based on the respective voltage requirements of the two electronic devices.

[0058] When three or four output ports 6 corresponding to the positions of the split-type PD power supply 4 are plugged into DC connection lines and connected to three or four electronic devices, the output principle is the same.

[0059] The maximum power that can be output by the above-mentioned embodiment 1 and embodiment 2 is the power of four split-type PD power supplies 4. The power output by each split-type PD power supply 4 is 60W, so the maximum output power of the four split-type PD power supplies 4 is 240W.

[0060] Example 3:

[0061] If four split PD power supplies 4 are placed in the frame 1, and a DC connection line is inserted into any output port 6 of the four split PD power supplies 4 to connect to an electronic device, the corresponding LED 12 on the frame 1 turns from green to red, and the electronic device sends a signal to the chip module 51 through the output port 6. After the chip module 51 makes a judgment based on the received signal, it sends a signal to the four split PD power supplies 4. The four split PD power supplies 4 provide relative voltage / current to the detection module 54 and the boost switching module 55 based on the received signal. At this time, the chip module 51 decides whether to start the boost switching module 55 and the boost switching parallel module 27 according to the individual voltage / current requirements of the electronic device before outputting it to the output port 6. This connection method can achieve a maximum output power of 240W for a single electronic device.

[0062] The specific power distribution method is as follows:

[0063] A: Four split PD power supplies 4 are inserted into the frame at the same time.

[0064] a1. Only one output port is connected to the electronic device for output (the other three output ports 6 are not used). In this way, the maximum output power of the electronic device is 240W (48V / 5A).
