The control circuit is provided with a plurality of network signal ports for connecting with the preset computer device, and the control circuit is provided with a first power input end and a second power input end; the first power input of the power supply unit and the control circuit The electrical connection and the battery backup and the power management module are electrically connected, and the power supply unit is configured to receive an external mains power and convert it into a first direct current, and then separately transmit to the first power input end of the control circuit and the battery preparation The power management module is supported; the battery backup and power management module is electrically connected to the second power input end of the control circuit and electrically connected to an external battery. When the utility power is in the power supply state, the external power supply is received by the power supply unit and replaced with the first direct current to be transmitted to the first power input end of the control circuit; when the commercial power is in the power off state, the battery backup and power management module Receiving the third direct current outputted by the external battery to be transmitted to the second power input end of the control circuit, thereby achieving the function of providing the mains power supply and the external battery backup power supply, so that the network switch of the creation is not supplied or disconnected by the commercial power supply. Electricity affects sustainable operations. At the same time, the battery backup and power management module can be used to manage the connection status and voltage detection of the external battery.

In order to make it easier for your examiner to understand the other features and advantages of this creation and the effects achieved by it, this article is combined with the drawings to describe in detail the features and advantages of this creation. The following examples are further The present invention is described in detail, but does not limit the scope of the present invention in any way.

Referring to FIG. 1 , the present disclosure discloses a network switch with embedded battery backup and power management. The network switch 1 includes a control circuit 11 , a power supply unit 12 , and battery backup and power management . Module 13.

The control circuit 11 is provided with a plurality of network signal ports, and the network signal ports are connected to the preset plurality of computer devices, and each computer device is connected to the network signal port of the network switch 1. Then, it is connected to a preset router or other network device to connect to the Internet; and the control circuit 11 is provided with a first power input terminal 111 and a second power input terminal 112.

The power supply unit 12 is electrically connected to the first power input terminal 111 of the control circuit 11, and is electrically connected to the battery backup and power management module 13. The power supply unit 12 is configured to receive an external mains 2 and externally power the mains. 2 is converted into a first DC output of a predetermined voltage/current; the voltage of the external mains 2 can be between 90V and 264V.

The battery backup and power management module 13 is electrically connected to the second power input terminal 112 of the control circuit 11 and the power supply unit 12, and the battery backup and power management module 13 includes a battery control unit 131. A battery charging unit 132 and a battery connection port 133. The battery control unit 131 is electrically connected to the second power input terminal 112 of the control circuit 11, and the battery control unit 131 can be used to detect the connection state of an external battery and detect the voltage of the external battery. The battery charging unit 132 is electrically connected to the power supply unit 12 and the battery control unit 131. The battery charging unit 132 is configured to receive the first DC power transmitted by the power supply unit 12 and convert it into a second DC power. Output. The battery port 133 is electrically connected to the battery charging unit 132 and the battery control unit 131 for electrically connecting to an external battery 3, and the external battery 3 can output a third DC power. The battery 3 can be a lead acid battery or a lithium battery.

When the utility power is in the power supply state, the external power supply is received by the power supply unit 12 And switching to the first direct current, and then transmitting the output power to the first power input end 111 of the control circuit 11, so that the control circuit 11 can operate normally. In addition, the power supply unit 12 can also transmit its output power to the battery charging unit 132. The battery charging unit 132 is configured to receive the first direct current transmitted by the power supply unit 12 and convert it into a second direct current output, and the battery charging unit 132.
