The terms "first", "second", etc. in the description and claims of the present invention or the above drawings are used to distinguish different objects and are not used to describe a specific order.

[0026] References to "embodiments" in this invention mean that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the invention. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an exclusive, independent, or alternative embodiment to other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0027] To enable those skilled in the art of this technology to better understand the solution of this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] As Figure 1 shown, as a preferred embodiment of this invention, this multifunctional intelligent charging socket device includes a socket body, an AC input interface connected to the mains power and provided on the socket body for inputting an AC power supply of 100V - 240V. There is also an AC charging interface directly connected to the AC input interface. The AC charging interface is provided with a two-hole interface and a three-hole interface to meet the power consumption needs of external AC electrical equipment. This example also additionally provides 2 DC interfaces of 12V 1A, and a group of fast charging interfaces (TYPE-C interface + USB-A interface). The 2 DC interfaces of 12V 1A can be externally connected to an optical modem and a router to provide the power connection needs of basic network devices. The TYPE-C interface or USB-A interface can be externally connected to charging devices such as cameras. The five different charging interfaces meet the power consumption needs of almost all devices. Of course, the number and type of the charging interfaces in this example can be adapted and adjusted according to requirements.

[0029] This example also includes a power supply circuit provided in the socket body. The input end of the power supply circuit is connected to the AC input interface, and the output end outputs power supply voltages to each charging interface respectively. The power supply circuit includes two parallel first switching power supply circuits, and a second switching power supply circuit connected in parallel with the first switching power supply circuit and connected to the USB interface and the TYPE-C interface respectively. The output ends of the first switching power supply circuits are connected to the DC interfaces in one-to-one correspondence.

[0030] The power supply circuit also includes an MCU, a first key switch and an indication module respectively connected to the MCU. The power supply circuit also includes a power-off control module for controlling the shutdown of the first switching power supply circuit. The control end of the power-off control module is connected to the control pin of the MCU. The MCU controls the first switching power supply circuit to restart regularly through the power-off control module. The user can control the time interval of the regular restart through the first key switch, and the indication module is used to indicate the duration of the set time interval.

[0031] The first push-button switch in this example is a mechanical push-button or a touch push-button. Of course, in this example, it can also be set as a push-button group composed of multiple push-buttons, corresponding to different duration adjustments respectively. The indication module in this example is an LED timing indicator light, and the number is the same as the number of different set timing times, which is used to indicate different durations. The indication module in this example can also be a display screen or a display tube, etc.

[0032] As Figure 1 and Figure 2 shown, in this example, the first switching power supply circuit of the first path converts alternating current into direct current output by the rectifier BD2, and then forms a switching power supply through the power supply chip U8 and the power supply chip U6 to provide a 12V 1A power output for the subsequent DC interface. Among them, the common-mode inductor LF1 is used to suppress electromagnetic interference, the thermistor NTC2 provides surge protection for the circuit, the varistor RTV1 provides lightning protection for the circuit, and short-circuit and over-current protection are achieved by connecting the fuse F1 in series on the live wire L.

[0033] The first switching power supply circuit of the second path in this example converts alternating current into direct current output by the rectifier BD3, and then forms a switching power supply through the power supply chip U11 and the power supply chip U10 to provide a 12V 1A power output for the subsequent DC interface.

[0034] As Figure 2 and Figure 3 shown, a switching transistor Q1 is also provided at the output end of the first switching power supply circuit of the first path in this example, and a switching transistor Q2 is also provided at the output end of the first switching power supply circuit of the second path. The pin 2 of the MCU in this example is connected to the control end of the switching transistor Q1, and together with the switching transistor Q1, it forms a power-off control module for the DC interface 1. When the restart time set by U9 (MCU) arrives, EN-A will output a low level to turn off the switching transistor Q1 to cut off the output voltage of the DC interface 1 and shut down the device. After the restart time ends, EN-A will output a high level to turn on Q1 to continue powering the device. The pin 3 of the MCU in this example is connected to the control end of the switching transistor Q2, and together with the switching transistor Q2, it forms a power-off control module for the DC interface 2. When the restart time set by U9 (MCU) arrives, EN-B will output a low level to turn off the switching transistor Q2 to cut off the output voltage of the DC interface 2 and shut down the device. After the restart time ends, EN-B will output a high level to turn on the switching transistor Q2 to continue powering the device.

[0035] Pin 5 of the MCU in this example is also connected to a button S1, which can set the restart time of DC interface 1 and DC interface 2. After power-on, the MCU U9 defaults to restart DC interface 1 and DC interface 2 every 72 hours, and the corresponding LED D6 lights up for indication. Press the button once, and the restart time becomes once every 144 hours. LED D6 goes out, and LED D7 lights up. Press the button again, and the restart time becomes once every 168 hours. LED D7 goes out, and LED D8 lights up, and so on in a cycle. The present invention greatly facilitates the operation of users through the button-type operation panel and the simple and intuitive LED timing indicator.

[0036] Preferably, this example also has a buzzer SP1 and a switching transistor Q3 for controlling the buzzer SP1. One minute before each restart of DC interface 1 and DC interface 2, the MCU U9 will control the buzzer SP1 to emit a sound. When the buzzer makes a sound and the button S1 has no action, DC interface 1 and DC interface 2 will restart according to the set time; when the buzzer makes a sound and the button is pressed once, DC interface 1 and DC interface 2 will re-count the time without restarting. Long press the button S1 to turn off the restart function of DC interface 1 and DC interface 2, and the device will always be powered on.

[0037] As Figure 1 、 Figure 4 and Figure 5 shown, the second switching power supply circuit in this example includes a power conversion unit and a fast charging protocol unit. The output terminals of the fast charging protocol unit are respectively connected to a USB interface and a TYPE-C interface. The fast charging protocol unit adaptively adjusts the fast charging power of the USB interface and / or the TYPE-C interface according to the external device conditions of the USB interface and the TYPE-C interface.

[0038] The power conversion unit in this example includes a rectifier DB1, power supply chips U1, U2 and their peripheral components. The rectifier DB1 converts AC into DC output. The fuse F1 provides short-circuit and over-current protection. The power supply chips U1, U2 convert the voltage into a suitable voltage output. The fast charging protocol unit in this example preferably uses a fast charging module U3 integrating PD3.0+QC3.0 dual protocols. The output terminals of the U3 are respectively connected to the USB interface and the TYPE-C interface TYPE-C1, and can provide 20W of power for TYPE-C1 and the USB interface. When using TYPE-C1 alone, it is PD20W. When using the USB alone, it is QC18W. When used together, the output is 5V3A MAX. The fast charging module U3 automatically adjusts the output voltage (5V / 9V / 12V) when it detects that a QC device is connected; when a PD fast charging protocol device is connected, it charges with 20W power through the CC line.

[0039] The present invention effectively solves the technical problems of the traditional socket with a single function, and the need for multiple independent power adapters for network devices and intelligent terminals. By setting a first switching power supply circuit, a dedicated DC power supply is directly provided for the network device through a DC interface, eliminating the need for an additional external power adapter and effectively improving the utilization rate of the socket. By setting an MCU and a breakpoint control module, intelligent management of the network device can be achieved. Regular restarting can restore the performance of the network device by 92%, effectively improving the operating efficiency of the network device. The whole process does not require manual operation and runs automatically, improving convenience.

[0040] As Figures 6 - 10 shown, in addition to the socket body 100, the multifunctional intelligent charging socket device in this example further includes a storage platform 200 detachably connected to the socket body 100.

[0041] In this example, the top surface of the socket body 100 is provided with a first step surface 107 and a second step surface 108 higher than the first step surface 107. The second step surface 108 is provided with an insertion slot 109. The lower surface of the storage platform 200 is provided with a first boss 203 that cooperates with the first step surface 107. The back surface of the storage platform 200 is provided with a second boss 204 that cooperates with the second step surface 108. A tongue 2041 is provided inside the second boss 204. An insertion channel 2042 is provided between the side wall of the second boss 204 and the tongue 2041. The tongue 2041 can be inserted into the insertion slot 109 to achieve the detachable connection between the storage platform 200 and the socket body 100. After the socket body 100 and the storage platform 200 are fixedly connected, the rear surface 2044 of the second boss 204 is flush with the back surface of the socket body 100. In this example, a fixing structure such as an adhesive can be provided on the rear surface 2044, so that the socket of the present invention can be fixed on the wall.

[0042] Preferably, the upper surface of the socket body 100 is embedded with the first boss 203 and the second boss 204. A first air duct 301 is provided between the second step surface 108 and the lower surface of the top surface of the second boss 204. A second air duct 302 is provided between the side wall of the second step surface 108 and the side wall of the second boss 204.

[0043] Furthermore, the upper surface of the first step surface 107 is provided with a ventilation slot 110. Third air ducts 2032 are respectively provided between the surface and the side wall of the first step surface 107 and the mating surface 2031 of the first boss 203. The third air ducts 2032 are communicated with the ventilation slot 110.

[0044] The storage platform 200 in this example includes a horizontally arranged first platform 202 and a second platform 201 vertically arranged with respect to the first platform 202, so as to adapt to the storage requirements for vertical wall mounting or flat plugging on a horizontal surface such as a desktop. The first platform 202 and the second platform 201 in this example are integrally arranged to improve the overall stability. Anti-slip matrices composed of a number of silicone anti-slip structures 205 are respectively provided on the first platform 202 and the second platform 201, improving the stability of product placement. Preferably, a fourth heat dissipation air duct 206 is further provided on the second platform 201 in this example. Of course, the fourth heat dissipation air duct 206 can also be provided on the first platform at the same time to increase air circulation and enhance the heat dissipation performance. When vertically plugged on the wall, the second platform 201 in this example maintains a certain distance from the wall through the second boss 204, and cooperates with the fourth heat dissipation air duct 206 to improve the heat dissipation effect of the charging device placed on the storage platform 200, thereby overcoming the technical problems of poor heat dissipation caused by stacking devices and potential safety hazards.

[0045] In addition, by providing a plurality of air ducts at the interface between the socket body 100 and the storage platform 200, the present invention can improve the heat dissipation effect when the plug is inserted into the charging interface for charging, and improve the safety of the socket body 100.

[0046] As an embodiment of the present invention, the storage platform 200 in this example preferably charges network devices and home cameras at the same time, thereby overcoming the drawback of the prior art that home cameras cannot be placed on the wall and need to be additionally installed with a fixing bracket, and also avoiding the problem of wiring for the device when pulling out the charger for the installed device, further improving the space utilization rate and the user's visual perception, and the device concentration can be increased by more than 60%.
