[0020] As can be understood, referring to FIGS. 1 to 4, the wall-mounted switching device according to an embodiment of the present application is a wall-mounted case 100 having a plurality of first through holes opened on a first surface and a second through hole opened on a second surface facing the first surface; A circuit section comprising an integrated circuit module, a PoE power receiving terminal 210, a PoE power supply terminal 220, a charging terminal 230, and a USB interface terminal 240, wherein the PoE power receiving terminal 210 is provided corresponding to a second through-hole, and the PoE power supply terminal 220, charging terminal 230, and USB interface terminal 240 are provided corresponding one-to-one to a plurality of first through-holes, Equipped with, The integrated circuit module is used to connect the PoE power receiving terminal 210 to the PoE power supply terminal 220, and the charging terminal 230 to the USB interface terminal 240, so that an external power supply provides power to the charging terminal 230 and / or the USB interface terminal 240 via the PoE power receiving terminal 210, and external equipment transmits and receives network data via the PoE power receiving terminal 210 and / or the USB interface terminal 240.

[0021] Therefore, by integrating the PoE power supply terminal 220, the charging terminal 230, and the USB interface terminal 240 into the same wall-mounted switching device, at least two different types of connection terminals can be provided to enable network connectivity, and power can be supplied simultaneously in at least two ways. At the same time, by using the PoE power receiving terminal 210 as a unified input for external power and a unified interaction port for interconnection networks, network wiring and power wiring can be simplified. The wall-mounted switching device according to the embodiment of the present invention has more features and can adapt to higher network power and network requirements, resulting in a better user experience.

[0022] In some embodiments, the charging terminal 230, USB interface terminal 240, and POE power supply terminal 220 can supply power simultaneously, while in other embodiments, only one or two of the charging terminal 230, USB interface terminal 240, and POE power supply terminal 220 supply power at the same time. However, the embodiments of this application are not limited to these, and those skilled in the art may selectively configure them according to their actual requirements. In some embodiments, the USB interface terminal 240 and POE power supply terminal 220 can transmit network data simultaneously, while in other embodiments, only one of the terminals can provide network transmission at the same time. In contrast, the embodiments of this application are not limited to enabling simultaneous transmission of network data between terminals, and those skilled in the art may selectively configure them according to their actual needs.

[0023] The embodiments of this application do not limit the specific structure of the wall-mounted case 100, and those skilled in the art may selectively configure it according to their actual requirements.

[0024] The charging terminal 230 is used to supply power to external equipment, the PoE power supply terminal 220 is the PSE terminal of the PoE, and the PoE power receiving terminal 210 is the PD terminal of the PoE. The embodiment of this application does not limit the specific circuit structure of the integrated circuit module, and the circuit may be selectively configured based on the specific connection relationships between ports and the functions of the ports.

[0025] The charging terminal 230 and the USB interface terminal 240 are physical ports of the same type; for example, both may be Type-C interfaces. However, in another embodiment, they may be physical ports of different types; for example, the charging terminal 230 may be Type-A and the USB interface terminal 240 may be Type-C. In contrast, the embodiments of the present application are not limited, and those skilled in the art may selectively configure them according to their actual requirements. Exemplarily, as shown in Figure 1, both the charging terminal 230 and the USB interface terminal 240 are Type-C connection terminals.

[0026] To make it clear, referring to Figures 2 to 4, the integrated circuit module includes a first circuit board 300, a second circuit board 400, and a third circuit board 500 stacked on top of each other. The first circuit board 300 integrates a first control circuit 310 that manages the charging terminal 230 and the USB interface terminal 240. The second circuit board 400 integrates an Ethernet switching circuit 410. The third circuit board 500 integrates a second control circuit 510. The three data connection terminals of the Ethernet switching circuit 410 are connected to the PoE receiving terminal 210, the PoE supplying terminal 220, and the first data terminal of the first control circuit 310, respectively. The second data connection terminal of the first control circuit 310 is connected to the USB interface terminal 240. The power supply input terminal of the second control circuit 510 is connected to the PoE receiving terminal 210, while the power supply output terminal is connected to the PoE supplying terminal 220 and the power supply input terminal of the first control circuit 310. The power supply output terminal of the first control circuit 310 is used to supply power to the charging terminal 230 and the USB interface terminal 240.

[0027] The embodiments of this application do not limit the method of electrical connection between the first circuit board 300, the second circuit board 400, and the third circuit board 500. In some embodiments, electrical connection is possible using individual connectors, while in other embodiments, circuit conductivity can be achieved by providing electrode pins in the wall-mounted case 100.

[0028] By providing the first control circuit 310 on the first circuit board 300, the second control circuit 510 on the third circuit board 500, and the Ethernet switching circuit 410 on the second circuit board 400, the high-voltage and low-voltage circuits can be placed on different circuit boards, thereby reducing the possibility of the high-voltage circuits interfering with the low-voltage circuits.

[0029] The first control circuit 310 controls the functional capability from an external power supply connected to the PoE receiving terminal 210 to the PoE supply terminal 220 and the second control circuit 510. The second control circuit 510 is used to control the power supplied to external equipment by the USB interface terminal 240 and the charging terminal 230, and to control the conversion of data transmission protocols between the USB interface terminal 240 and the Ethernet switching circuit.

[0030] The Ethernet switching circuit 410 controls the transmission and reception of network data between the PoE power supply terminal 220 and the PoE power receiving terminal 210, as well as the transmission and reception of Ethernet protocol data, enabling external equipment to communicate with the interconnected network via the PoE power supply terminal 220 or the USB interface terminal 240.

[0031] To make it clear, referring to Figures 1 and 2, the first circuit board 300 is located close to the first surface of the wall-mounted case 100, the second circuit board 400 is located between the first circuit board 300 and the third circuit board 500, and the third circuit board 500 is located close to the second surface of the wall-mounted case 100.

[0032] Since the Ethernet switching circuit 410 is integrated on the second circuit board 400 and the second control circuit 510 is integrated on the third circuit board 500, when the switching device is in operation, the temperature of the third circuit board 500 will be higher than that of the second circuit board 400, and the temperature of the second circuit board 400 will be higher than that of the first circuit board 300. By sequentially stacking the first circuit board 300, the second circuit board 400, and the third circuit board 500, and by placing the first circuit board 300 close to the user, the risk of burns due to excessive temperature rise during user use can be reduced, resulting in a better user experience.

[0033] As can be understood, the first circuit board 300 and the second circuit board 400 are electrically connected detachably via the first connector, while the second circuit board 400 and the third circuit board 500 are electrically connected detachably via the second connector.

[0034] The first and second connectors enable detachable and electrical connections between the first circuit board 300, the second circuit board 400, and the third circuit board 500, thereby improving the convenience of mounting the circuit components. The PIN pins in the first and second connectors may be selectively set according to the actual electrical connection requirements, and these will not be described again in the embodiments of this application.

[0035] The first circuit board 300, the second circuit board 400, and the third circuit board 500 are physically detachable connections, which can be fixed by, for example, engagement or insertion. However, in another embodiment, the first circuit board 300, the second circuit board 400, and the third circuit board 500 are electrically detachable connections, which can be implemented by, for example, an electrical path using a connector.

[0036] To be understood, the first connector includes a male connector and a female connector, and the first circuit board 300 is provided with a second through-hole that corresponds one-to-one with the insertion holes in the female connector. The connecting pins of the male connector are inserted into the female connector by passing through the second through-hole.

[0037] By providing a second through-hole, the connecting pins of the male connector can be passed through the second through-hole and inserted into the female connector, enabling reverse mounting of the female connector on the first circuit board 300. This shortens the distance between the first circuit board 300 and the second circuit board 400, thereby reducing the overall volume of space occupied by the circuit section.

[0038] To ensure clarity, the connectors on both the second circuit board 400 and the third circuit board 500 are properly mounted.

[0039] In embodiments of the present application, the circuit boards on which the male and female connectors are provided are not limited. In some embodiments, the male connector is provided on the second circuit board 400 and the female connector is provided on the first circuit board 300. In another embodiment, the male connector is provided on the first circuit board 300 and the female connector is provided on the second circuit board 400. Those skilled in the art may selectively set the male connector to the first circuit board 300 and the second circuit board 400 according to the minimum distance required between them. If the height of the male connector portion satisfies the distance between the first circuit board 300 and the second circuit board 400, and the height of the male connector portion is less than the height of the female connector, the male connector can be provided on the second circuit board 400 to further shorten the distance between the first circuit board 300 and the second circuit board 400.

[0040] To make it clear, referring to Figures 1 and 2, the PoE receiving terminal 210 and the PoE supplying terminal 220 are located on opposite sides and two opposite ends of the second circuit board 400, respectively, with the PoE supplying terminal 220 located in the center of the corresponding end and the PoE receiving terminal 210 located diagonally across the corresponding end.

[0041] For example, as shown in Figure 2, by providing the POE power receiving terminal 210 on the diagonal of the second surface of the second circuit board 400 adjacent to the wall-mounted case 100, the third circuit board 500 can be integrated with as much space as possible.

[0042] To make it clear, referring to Figure 3, the end face of the POE power receiving terminal 210 is flush with the third circuit board 500, or lower than the face of the third circuit board 500 that is close to the wall-mounted case 100.

[0043] By making the end face of the POE power receiving terminal 210 flush with the third circuit board 500 or lower than the face of the third circuit board 500 that is close to the wall-mounted case 100, an external power supply can be easily connected via the POE power receiving terminal 210 after the wall-mounted case 100 is installed, thereby reducing the requirements for the external mounting environment.

[0044] To make it clear, referring to Figures 4, 5a-5c, the second control circuit 510 includes a PD interface controller 511, a PSE interface controller 512, a first transistor 513, and a first step-down circuit 514. The gate control terminal of the PD interface controller 511 is connected to the gate of the first transistor 513, while the drain of the first transistor 513 is connected to the POE receiving terminal 210 and the power supply input terminal of the PD interface controller 511. The source of the first transistor 513 is connected to the power supply input terminal of the PSE interface controller 512, the power supply control terminal of the PD interface controller 511, and the power supply input terminal of the first step-down circuit 514, while the power supply output terminal of the PSE interface controller 512 is connected to the POE power supply terminal 220. The first step-down circuit 514 is used to supply a power supply voltage to the first control circuit 310 for charging the charging terminal 230.

[0045] The PD interface controller 511 is used to control the power supply output to the POE power receiving terminal 210, the PSE interface controller 512 is used to control the power supply output to the POE power supply terminal 220, and the first step-down circuit 514 is used to step down the voltage output from the power supply control terminal of the PD interface controller 511 to a preset power supply voltage. In some embodiments, the first step-down circuit 514 can also be used to supply the operating voltage to the integrated chip in the first control circuit 310, and this is not limited to the embodiments of the present application, and those skilled in the art may selectively set it according to the actual situation. In the embodiments of the present application, the specific model numbers of the PD interface controller 511 and the PSE interface controller 512 are also not limited; for example, in some embodiments, the PD interface controller 511 is set to SQ24902FBC. In some embodiments, the PSE interface controller 512 is set to IP802BR. The first step-down circuit 514 may be selected to use a specific step-down chip according to the voltage required for the circuit.

[0046] For illustrative purposes, let's designate the PD interface controller 511 as U1, with the model number SQ24902FBC, the PSE interface controller 512 as U2, with the model number IP802BR. Let the first transistor 513 be Q1. If the POE power supply terminal 220 is J1, as shown in Figure 5a, the power supply input terminal VPORT of U1 is connected to the POE power receiving terminal 210 via the common-mode inductor L1 and switch J3. The drain of Q1 is connected to L1 and the power supply input terminal VPORT. As shown in Figures 5a and 5b, the source of Q1 is connected to the power supply control terminal HSSRC of U1 and the power supply input terminal V54 of U2. When the gate control terminal HSGATE of U1 conducts Q1, the source of Q1 supplies voltage to the power input terminal V54 of U2. Referring to Figure 6, the gate control terminal CH0N of U2 is connected to the power pins V54 and P0_NEG of J1 via interfaces J4 and J6. As shown in Figure 5c, the first buck circuit 514 includes a buck chip U3, a second transistor Q2, and a third transistor Q3, with the source of Q2 and the drain of Q3 interconnected. The bootstrap control terminal BST1 of U3 is connected to the connection point between the source of Q2 and the drain of Q3. The gate of Q3 is connected to the low-side gate control terminal LO of U3. The source of Q3 is grounded. The gate of Q2 is connected to the high-side gate control terminal HO of U3, and its source is connected to the source of Q1. The power input terminal VIN of U3 is connected to the source of Q1. By controlling the conduction between Q2 and Q3 using HO and LO, the voltage output from the connection point between the source of Q2 and the drain of Q3 can be set to 24V, thereby supplying a 24V voltage to the first control circuit 310.

[0047] To make it clear, refer to Figures 4 and 8a-8c, using them as examples, the first control circuit 310 includes a charging chip 311, a PD communication chip 312, an Ethernet controller chip 313, a first switch circuit 314, and a second switch circuit 315.

In the first switch circuit 314, the power output terminals corresponding one-to-one to its power control terminals are connected to the power control terminals of the second switch circuit 315 and the charging terminal 230, respectively. The switch control terminals of the second switch circuit 315 are connected to the switch control terminals of the PD communication chip 312. The power output terminals of the second switch circuit 315 are connected to the USB interface terminal 240. The data connection terminal of the Ethernet controller chip 313 is connected to the first data connection terminal of the USB interface terminal 240, and the second data connection terminal of the USB interface terminal 240 is connected to one of the data connection terminals of the Ethernet switching circuit 410.

[0048] The charging chip 311 is used to manage the charging terminal 230 and supply power voltage to the PD communication chip 312, and the PD communication chip 312 is used to manage the power supply capability of the USB interface terminal 240. The Ethernet controller chip 313 is used to convert USB protocol data signals into Ethernet protocol data signals to accommodate data transmission between the POE power supply terminal 220 and the USB interface terminal 240. In the embodiments of this application, the model numbers of the charging chip 311, PD communication chip 312, and Ethernet controller chip 313 are not limited. For example, the Ethernet controller chip 313 is set to AX88179A, the charging chip 311 is set to SW3557U, and the PD communication chip 312 is set to LDR6023AQ. The switch control terminal of the charging chip 311 and the power supply output terminal and power supply control terminal of the first switch circuit 314 are set to correspond one-to-one.

[0049] The first switch circuit 314 is used to control the power supply capability from the power supply output terminal of the charging chip 311 to the PD communication chip 312 and the charging terminal 230 based on the switch control terminal of the charging chip 311, while the second switch circuit 315 is used to control the power supply capability from the power supply output terminal of the PD communication chip 312 to the USB interface terminal 240 based on the switch control terminal of the PD communication chip 312.

[0050] In some embodiments, as shown in Figure 8a, the first switch circuit 314 includes a fourth transistor Q4 and a fifth transistor Q5, the gates of Q4 and Q5 are connected to the two switch control terminals of the charging chip 311, respectively, as the switch control terminals of the first switch circuit 314, the drains of Q4 and Q5 are connected to the power supply output terminals of the charging chip 311, respectively, as the power supply control terminals of the first switch circuit 314, and the sources of Q4 and Q5 are connected to the power supply control terminals of the second switch circuit 315, the charging terminal 230 (i.e., J12 shown in Figure 8a), respectively, as the power supply output terminals of the first switch circuit 314.
