[0029] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0030] See also Figure 1 The present application provides a home data management device 100. The home data management device 100 includes a network communication module 10, a network attached storage module 20, a conversion circuit 30 and a battery 40.

[0031] The network communication module 10 includes a WAN network interface, which is connected to the modem through the WAN network interface, and the network communication module 10 realizes the network connection between the wide area network and the local area network. Among them, the network communication module 10 can be a router, or other devices that can realize the network connection between the wide area network and the local area network. The WAN network interface can be a network interface corresponding to the router. That is, the WAN network interface is connected to the modem to realize the connection with the external network (such as the Internet). The WAN interface is the interface for the network communication module 10 to connect to the external network (such as the Internet).

[0032] The NAS module 20 is in communication with the network communication module 10, and the NAS module 20 can realize networking function through the network communication module 10. The NAS module 20 is used to process data storage and file sharing requests. For example, the NAS module 20 can be a NAS device.

[0033] The network attached storage module 20 can communicate with the network communication module 10 to realize the networking function, so that the network attached storage module 20 can access the local area network, thereby realizing the communication and data transmission between the network attached storage module 20 and other network devices, making data storage and access in the network more flexible and efficient.

[0034] It is understandable that in the relevant technology, the NAS device and the router are two separate components that are physically connected via a long network cable. When the NAS device is connected to the router via the network cable, there is a possibility of poor connection due to various factors such as physical connection problems, environmental interference, router port limitations, inconsistent network cable interface standards, and human operational errors.

[0035] In view of this, since the home data management device 100 of the present application integrates the network communication module 10 and the network attached storage module 20, the network attached storage module 20 is connected to the network communication module 10 for communication, and the network attached storage module 20 can realize the networking function through the network communication module 10, so that the network attached storage module 20 and the network communication module 10 can be directly connected through the circuit board inside the home data management device 100, without setting a long network cable. This method simplifies the connection process, reduces the clutter of cables, and also ensures the stability and speed of data transmission between the network communication control module 10 and the network attached storage module 20.

[0036] In addition, in other implementations, an internal switch may also be designed inside the home data management device 100 , and the internal switch is used to connect the network communication module 10 and the network attached storage module 20 .

[0037] That is, the network attached storage module 20 and the network communication module 10 in the home data management device 100 of the present application do not need to be connected through an additional network cable, which can avoid the problem of poor connection between the NAS device and the router in the related art that the NAS device needs to be connected to the router through an additional network cable.

[0038] The conversion circuit 30 includes an AC / DC conversion circuit 31 and a DC conversion circuit 32. The conversion circuit 30 can be electrically connected to the mains and provide power to the network communication module 10 and the network attached storage module 20 after conversion by the AC / DC conversion circuit 31. The AC / DC conversion circuit 31 refers to a circuit that can convert AC power into DC power, and also convert DC power into AC power. The DC conversion circuit 32 refers to a circuit that converts DC power into DC power of different voltages.

[0039] The battery 40 is electrically connected to the conversion circuit 30 . When the mains is connected, the battery 40 is charged through the AC / DC conversion circuit 31 . When the mains is disconnected, the battery 40 supplies power to the network communication module 10 and the network attached storage module 20 through the DC conversion circuit 32 .

[0040] In detail, a first end of the AC / DC conversion circuit 31 is connected to the mains, a second end of the AC / DC conversion circuit 31 is connected to a first end of the DC conversion circuit 32, a second end of the DC conversion circuit 32 is connected to the battery 40, and a third end of the DC conversion circuit 32 is connected to the network communication module 10 and the network attached storage module 20 respectively.

[0041] When the AC power is connected, the AC power is converted into DC power by the AC-DC conversion circuit 31 , and then the DC power is converted into DC power of different voltages by the DC conversion circuit 32 to power the network communication module 10 and the network attached storage module 20 .

[0042] When the mains power is disconnected, the battery 40 can output direct current to the direct current conversion circuit 32 to supply power to the network communication module 10 and the network attached storage module 20 .

[0043] That is, the present application provides a battery 40 inside the home data management device 100, and when the city power is cut off, the battery 40 can be used to power the network communication module 10 and the network attached storage module 20, thereby avoiding the situation where the network communication module 10 and the network attached storage module 20 cannot be used due to power outage.

[0044] In this way, the network attached storage module 20 and the network communication module 10 in the home data management device 100 of the present application are integrated together, and there is no need to connect the two through a long network cable, which can avoid the problem of poor connection between the NAS device and the router in the related art that the NAS device needs to be connected to the router through a long network cable. In addition, in the case of a power outage, the home data management device 100 can switch to powering the network communication module 10 and the network attached storage module 20 through the battery 40, which can avoid the situation where the network communication module 10 and the network attached storage module 20 cannot be used due to a power outage.

[0045] In some embodiments, the home data management device 100 further includes an Ethernet cable, which is disposed inside the home data management device 100 , and the network communication module 10 and the network attached storage module 20 are communicatively connected via the Ethernet cable.

[0046] Specifically, Ethernet cables are able to support data transfer rates up to 10Gbps or even higher. This enables it to meet the needs of modern homes and businesses for high-speed network connections. For example, Ethernet cables can provide stable and high-speed network connections when performing bandwidth-intensive tasks such as large file transfers, video conferencing, or streaming high-definition content playback.

[0047] Ethernet cables can support multiple network protocols, which allows them to play a role in different network environments. Whether it is TCP / IP protocol or other network protocols, Ethernet cables can provide a stable physical connection to ensure that data can be transmitted smoothly between devices.

[0048] Compared with wireless connection, Ethernet cable connection is more stable and reliable. It is not affected by wireless signal interference and distance limitation, and can provide a more stable and reliable network connection, which can be applied to application scenarios with high reliability and stability.

[0049] In this way, an Ethernet cable may be provided inside the home data management device 100 of the present application, and the network communication module 10 and the network attached storage module 20 may achieve a stable, reliable, and high-speed communication connection between the two via the Ethernet cable.

[0050] See also Figure 2 In some embodiments, the home data management device 100 further includes a power output port 50 and a control module 60. The control module 60 is connected to the conversion circuit 30, and the power output port 50 is connected to the conversion circuit 30. The control module 60 is used to control the conversion circuit 30 to obtain power from the battery 40 to output power to the external device through the power output port 50 when the city power is cut off.

[0051] Specifically, the external device may be, for example, an electronic device such as a computer, a mobile phone, a tablet, etc., which is not limited here.

[0052] That is, when the city power is off and the battery 40 has power, the control module 60 can control the conversion circuit 30 to obtain power from the battery 40 and then output the power through the power outlet 50 to power external devices.

[0053] See also Figure 2 and Figure 3 In some embodiments, the power output port 50 includes an AC output port 51 and an AC input port 52, the AC input port 52 can be connected to the mains, and the AC output port 51 is connected to the battery 40 (such as Figure 2 ) or directly electrically connected to the AC input port 52 (as shown Figure 3 shown).

[0054] That is, when the AC power is connected to the AC input port 52, the home data management device 100 of the present application can bypass the AC power and directly supply power to the AC output port 51. For example, the AC output port 51 can be electrically connected to the modem, so that the modem is powered by the AC output port 51.

[0055] When the mains power is disconnected from the AC input port 52, the home data management device 100 of the present application can supply power to the AC output port 51 through the battery 40 and the AC / DC conversion circuit 31, that is, the AC / DC conversion circuit 31 can convert the DC power obtained from the battery 40 into AC power, so that the AC power can be output to an external device through the AC output port 51. For example, at this time, the AC output port 51 can also be electrically connected to a modem, so that the modem is supplied with power through the AC output port 51.

[0056] See also Figure 2 In some embodiments, the power output port 50 may further include a DC output interface 53 . The DC output interface 53 is connected to the DC conversion circuit 32 .

[0057] Specifically, in one embodiment, Figure 4 As shown, the DC conversion circuit 32 may include a first DC converter 321 and a second DC converter 322. A first end of the first DC converter 321 is connected to the AC-DC conversion circuit 31, a second end of the first DC converter 321 is respectively connected to the network communication module 10 and the network attached storage module 20, a third end of the first DC converter 321 is connected to the battery 40, a fourth end of the first DC converter 321 is connected to a first end of the second DC converter 322, and a second end of the second DC converter 322 is connected to the DC output interface 53. The first DC converter 321 is used to provide corresponding DC power to the network communication module 10 and the network attached storage module 20, and the second DC converter 322 is used to provide corresponding DC power to the external device.

[0058] That is, when the AC power is connected to the AC input port 52, the AC power can also supply power to the DC output port 53 through the AC-DC conversion circuit 31 and the DC conversion circuit 32, that is, the AC power is converted by the AC-DC conversion circuit 31 and the DC conversion circuit 32 to obtain DC power, so that the home data management device 100 of the present application can output DC power to external devices through the DC output interface 53.

[0059] When the AC power is disconnected from the AC input port 52, the home data management device 100 of the present application can also supply power to the DC output interface 53 through the battery 40 and the DC conversion circuit 32, that is, the DC conversion circuit 32 can convert the DC power obtained from the battery 40 into DC power, so that the DC power can be output to the external device through the DC output interface 53.

[0060] See also Figure 5 In some embodiments, the home data management device 100 further includes a LAN network interface 70. The LAN network interface 70 is a physical interface for external devices to connect to the Internet.

[0061] Specifically, a LAN network interface is a physical interface on a router or other network device. A LAN network interface is an indispensable part of network connection. It is responsible for connecting the router with devices in the local area network and realizing communication and data sharing between devices. At the same time, a LAN network interface also supports multiple speeds, provides stable network connections, and is widely used in various fields.

[0062] That is, the LAN interface is used to connect external devices in the local area network. These external devices communicate and share data with the Internet through the router. The external devices can be computer devices, printing devices, multimedia devices, smart home devices or other devices, without limitation.

[0063] like Figure 5 As shown, the home data management device 100 further includes an antenna 71. The antenna 71 is used to provide a wireless network.

[0064] Thus, the home data management device 100 of the present application is provided with a LAN network interface 70, which can provide a network access path for external devices.

[0065] See also Figure 5 In some implementations, the home data management device 100 further includes a hard disk interface 80. The hard disk interface 80 is used to insert a hard disk.

[0066] Specifically, the hard disk interface 80 provides necessary physical and electrical connections to ensure that the hard disk can communicate and transfer data with the NAS module 20 .

[0067] After a hard disk is inserted into the hard disk socket 80 , a user can access data stored on the hard disk, such as by running an operating system, opening an application program, and viewing a file.

[0068] The home data management device 100 of the present application can achieve physical and electrical connection between the hard disk and the network attached storage module 20 by providing a hard disk socket 80, thereby allowing the user to read and write data stored on the hard disk and ensuring data security and backup.

[0069] In some implementations, the home data management device 100 further includes a wireless communication module. The wireless communication module is used to connect to an external device and control or access the functional modules in the home data management device 100 through the external device.

[0072] That is, the home data management device 100 of the present application may be provided with a Bluetooth module, connected to an external device via Bluetooth, and the functional modules in the home data management device 100 may be controlled or accessed via the external device. For example, the external device may control the output of the conversion circuit 30, the external device may control the storage or reading of data in the NAS device, and the external device may control the visitor restriction of the router, etc.

[0073] See also Figure 6 The present application also provides a control method, which is applied to the home data management device 100 described in any one of the above embodiments. The control method includes:

[0074] 01: When the city power is normal and the power output port 50 of the home data management device 100 outputs AC power, the power output port 50 is controlled to output AC power to supply power to the first external device;

[0075] 02: When the city power is cut off, the control is switched to the direct current output by the battery 40 of the home data management device 100, which is processed to obtain alternating current and then output to the first external device through the power output port 50 to supply power to the first external device.

[0076] The present application also provides a control device, which may include the control module 60 described above. Steps 01 and 02 may be implemented by the control module 60. That is, the control module 60 is used to control the power output port 50 to output AC power to power the first external device when the city power is normal and the power output port 50 of the home data management device 100 outputs AC power; when the city power is off, the control is switched to the DC power output by the battery 40 of the home data management device 100, which is processed to obtain AC power, and then output to the first external device through the power output port 50 to power the first external device.

[0077] Specifically, the first external device may be, for example, a modem or other device, which is not limited here. At this time, the power output port 50 includes the AC output port 51 described above, and the AC output port 51 outputs AC power to power the first external device.

[0078] When the mains power is normal, the modem can be powered by outputting AC power through the power output port 50 in a bypass manner.

[0079] In addition, the home data management device 100 may also include an inverter, the battery 40 may be connected to the inverter, and the inverter may convert the direct current (DC) provided by the battery 40 into alternating current (AC) to match the needs of the modem and other first external devices that require AC power.

[0080] That is, the control method of the present application can control the power output port 50 to output AC power to power the first external device when the AC power is normal and the power output port 50 of the home data management device 100 outputs AC power. When the AC power is cut off, the control is switched to provide AC power to the first external device through the battery 40 of the home data management device 100. This can avoid power outages when the home data management device 100 is used to power the first external device such as a modem, thereby improving the user experience.

[0081] See also Figure 7 In some embodiments, the control method further comprises:

At this time, the power output port 50 includes the DC output port 53 described above, and the DC output port 53 outputs DC power to supply power to the second external device.

[0086] The control method of the present application can control the power output port 50 to output direct current to power a second external device when the AC power is normal and the power output port 50 outputs direct current. When the AC power is cut off, the control is switched to provide direct current power to the second external device through the battery 40. This can avoid power outages when the home data management device 100 is used to power a second external device such as a mobile phone, computer, or iPad, thereby improving the user experience.
