[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Usually, the components of the embodiments of the present application described and shown in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application claimed, but only represents the selected embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.

[0033] It should be noted that: similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0034] In the description of the present application, it should be noted that relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. The term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium.

[0035] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0036] As described in the background technology, the maximum charging power of the downstream port of the current USB hub is only 1.5A / 5V, which cannot meet the needs of some customers. In addition, since the interfaces of USB devices on the market are not unified, some use Type-A interfaces, and some use Type-C interfaces, the number of downstream ports of the current USB hub is small and cannot adapt to different types of USB devices.

[0037] Therefore, how to improve the charging power of the USB hub so that the USB hub can simultaneously perform data transmission and fast charging for different types of USB devices is a technical problem that needs to be solved urgently by those skilled in the art.

[0038] To solve the above technical problems, please refer to Figure 1 The embodiment of the present application provides a USB hub 10. The USB hub 10 includes: a USB hub body 110, an upstream connector module 120, a plurality of first USB Type-A connectors 130, a plurality of first USB Type-C connectors 140 and a plurality of PD fast charging chips 150.

[0039] The USB hub body 110 in the embodiment of the present application has an upstream port and multiple downstream ports, wherein one end of the upstream connector module 120 is connected to the upstream port of the USB hub body 110, and the other end of the upstream connector module 120 is connected to the host.

[0040] Since the first USB Type-A connector 130 can only be inserted from one side, while the first USB Type-C connector 140 can be inserted from both sides (i.e., the front side and the back side), the first USB Type-A connectors 130 are connected to the downstream ports of the USB hub body 110 in a one-to-one manner, and the first USB Type-C connectors 140 are connected to the downstream ports of the USB hub body 110 in a one-to-two manner.

[0041] Equivalently, one first USB Type-A connector 130 is connected to one downstream port of the USB hub body 110, and one first USB Type-C connector 140 is connected to two downstream ports of the USB hub body 110. By providing a plurality of first USB Type-A connectors 130 and a plurality of first USB Type-C connectors 140, it is ensured that the USB hub 10 can adapt to different types of USB devices.

[0042] In addition, since the first USB Type-A connector 130 only supports the BC1.2 fast charging protocol, its maximum charging power is only 1.5A / 5V. Therefore, in order to increase the charging power of the USB hub 10, a plurality of first USB Type-C connectors 140 are also connected to a plurality of PD fast charging chips 150 in a one-to-one manner.

[0043] By connecting the first USB Type-C connector 140 to the PD fast charging chip 150, the first USB Type-C 140 connector supports the PD3.0 (Power Delivery 3.0, version 3.0 of the power transmission protocol) fast charging protocol, thereby achieving various charging powers such as 3A / 5V, 13A / 2V, 3A / 9V, 3A / 15V, 5A / 20V, etc.

[0044] Based on the above design, a plurality of first USB Type-A connectors 130 and a plurality of first USB Type-C connectors 140 in the embodiments of the present application can both perform data transmission and fast charging on USB devices, and a plurality of first USB Type-C connectors 140 all support the PD3.0 fast charging function, increasing the charging power of the USB hub 10 and meeting the charging requirements of different types of USB devices.

[0045] In order to increase the number of downstream ports of the USB hub body 110, so as to perform data transmission and fast charging on more USB devices, in the embodiments of the present application, the USB hub body 110 includes a plurality of USB hub chips. Among them, each USB hub chip includes an upstream port and a plurality of downstream ports.

[0046] To facilitate the description of the connection relationship between the plurality of USB hub chips and the plurality of first USB Type-A connectors 130 and the first USB Type-C connectors 140, hereinafter, it is described by taking the USB hub chip including an upstream port and four downstream ports as an example.

[0047] Please refer to Figure 2 , in the embodiments of the present application, the USB hub body 110 includes a first USB hub chip 111, a second USB hub chip 112, and a third USB hub chip 113.

[0048] The upstream port UP1 of the first USB hub chip 111 is connected to the upstream connector module 120, the first downstream port DP11 of the first USB hub chip 111 is connected to the upstream port UP2 of the second USB hub chip 112, and the second downstream port DP12 of the first USB hub chip 111 is connected to the upstream port UP3 of the third USB hub chip 113.

[0049] The number of downstream ports of the USB hub main body 110 is expanded to 8 through cascading the first USB hub chip 111, the second USB hub chip 112, and the third USB hub chip 113. Among them, the four downstream ports of the second USB hub chip 112 and the four downstream ports of the third USB hub chip 113 are both connected to a plurality of first USB Type-A connectors 130 and a plurality of first USB Type-C connectors 140.

[0051] As an alternative implementation, as Figure 2 shown, the USB hub includes four first USB Type-A connectors 130, two first USB Type-C connectors 140, and two PD fast charging chips 150. Among them, the first downstream port DP21, the second downstream port DP22, the third downstream port DP23, and the fourth downstream port DP24 of the second USB hub chip 112 are respectively connected to a first USB Type-A connector 130 in a one-to-one manner.

[0052] The first downstream port DP31 and the second downstream port DP32 of the third USB hub chip 113 are connected to a first USB Type-C connector 140 in a two-to-one manner, and the third downstream port DP33 and the fourth downstream port DP34 of the third USB hub chip 113 are connected to another first USB Type-C connector 140 in a two-to-one manner. Moreover, each first USB Type-C connector 140 is also respectively connected to a PD fast charging chip 150 in a one-to-one manner.

[0053] As another alternative implementation, as Figure 3 shown, the USB hub includes two first USB Type-A connectors 130, three first USB Type-C connectors 140, and three PD fast charging chips 150. Among them, the first downstream port DP21 and the second downstream port DP22 of the second USB hub chip 112 are respectively connected to a first USB Type-A connector 130 in a one-to-one manner.

[0054] The third downstream port DP23 and the fourth downstream port DP24 of the second USB hub chip 112, the first downstream port DP31 and the second downstream port DP32 of the third USB hub chip 113, and the third downstream port DP33 and the fourth downstream port DP34 of the third USB hub chip 113 are respectively connected to a first USB Type-C connector 140 in a two-to-one manner. Moreover, each first USB Type-C connector 140 is also respectively connected to a PD fast charging chip 150 in a one-to-one manner.

[0055] By connecting the second USB hub chip 112 and the third USB hub chip 113 to the downstream ports of the first USB hub chip 111, the number of downstream ports of the USB hub main body 110 is doubled, thereby enabling data transmission and fast charging for more USB devices.

[0056] Since the number of downstream ports of the first USB hub chip 111 is generally four, to further increase the number of downstream ports of the USB hub main body 110, please refer to Figure 4 . In a feasible implementation manner, the USB hub main body 110 further includes a fourth USB hub chip 114 and a fifth USB hub chip 115.

[0057] Among them, the third downstream port DP13 of the first USB hub chip 111 is connected to the upstream port UP4 of the fourth USB hub chip 114, and the fourth downstream port DP14 of the first USB hub chip 111 is connected to the upstream port UP5 of the fifth USB hub chip 115. The multiple downstream ports of the fourth USB hub chip 114 and the multiple downstream ports of the fifth USB hub chip 115 are both connected to multiple first USB Type-A connectors 130 and multiple first USB Type-C connectors 140.

[0058] It should be noted that the embodiments of the present application do not limit the connection manners between the second USB hub chip 112, the third USB hub chip 113, the fourth USB hub chip 114, the fifth USB hub chip 115 and the multiple first USB Type-A connectors 130 and the first USB Type-C connector 140. It only needs to ensure that a first USB Type-A connector 130 is connected to a downstream port, and a first USB Type-C connector 140 is respectively connected to two downstream ports and a PD fast charging chip 150.

[0059] For example, as Figure 4As shown in the figure, the USB hub includes four first USB Type-A connectors 130, six first USB Type-C connectors 140, and six PD fast charging chips 150. Among them, the first downstream ports DP21, DP22, DP23, and DP24 of the second USB hub chip 112 are respectively connected to a first USB Type-A connector 130 in a one-to-one manner.

[0060] For the third USB hub chip 113, the fourth USB hub chip 114, and the fifth USB hub chip 115, every two downstream ports are respectively connected to a first USB Type-C connector 140 in a two-to-one manner. Moreover, each first USB Type-C connector 140 is also respectively connected to a PD fast charging chip 150 in a one-to-one manner.

[0061] By cascading the first USB hub chip 111, the second USB hub chip 112, the third USB hub chip 113, the fourth USB hub chip 114, and the fifth USB hub chip 115, the number of downstream ports of the USB hub body 110 is expanded to 16, greatly increasing the number of downstream ports of the USB hub body 110.

[0062] By connecting a part of the downstream ports of the USB hub body 110 to a plurality of first USB Type-A connectors 130 in a one-to-one manner, connecting another part of the downstream ports to a plurality of first USB Type-C connectors 140 in a two-to-one manner, and each first USB Type-C connector 140 is also connected to a PD fast charging chip 150 in a one-to-one manner, not only the charging power of the USB hub is improved, but also the USB hub can simultaneously perform data transmission and fast charging on different types of USB devices.

[0063] Furthermore, in order to enable different types of USB devices to communicate with the host, the specific structure of the upstream connector module 120 in the embodiments of the present application is divided into two types.

Among them, the first interface conversion chip 123 is used to convert and transmit signals between the USB hub main body 110 and the second USB Type-C connector 122.
