The applicant has found through research that the traditional ear-wing module includes two ear-wing components, which are distributed on the left and right sides of the front window of the server and form a chassis with the front window. One ear-wing component includes a circuit board and a key display component, two USB interfaces and other components arranged on the circuit board, and the other ear-wing component includes another circuit board and a VGA interface, an RJ45 interface and other components arranged on the circuit board. It can be seen that the traditional ear-wing module needs to be equipped with two circuit boards to complete the arrangement of the above components and form two ear-wing components with different components, which makes the integration of the ear-wing module low and the space utilization rate low.

To this end, please refer to Figures 1 and 2, Figure 1 shows a schematic diagram of the structure of the ear wing module 10 in an embodiment of the present application, and Figure 2 is a schematic diagram of a portion of the structure in Figure 1. An embodiment of the present application provides an ear wing module 10 which is generally used in a server. The ear wing module 10 includes at least one ear wing assembly 100. The ear wing assembly 100 includes a circuit board 110 and a key display 120 electrically connected to the circuit board 110, a first adapter interface 130 and a second adapter interface 140. The first adapter interface 130 is used to transfer out a plurality of USB interfaces. Specifically, the first adapter interface 130 is externally connected to a first adapter, and the first adapter has a plurality of USB interfaces. The second adapter interface 140 is used to transfer out a COM interface, a VGA interface and an I3C interface. Specifically, the second adapter interface 140 is externally connected to a second adapter, and the second adapter has a COM interface, a VGA interface and an I3C interface.

In specific configuration, an ear wing assembly 100 includes a circuit board 110, and the first adapter interface 130 generally transfers out two USB interfaces. The first adapter interface 130, the second adapter interface 140 and the key display 120 are arranged at intervals on the circuit board 110. Through the above configuration, the present application utilizes the first adapter interface 130 to transfer out multiple, i.e., at least two USB interfaces, which on the one hand realizes that the ear wing assembly 100 has the function of two USB interfaces, and on the other hand reduces the volume originally occupied by the two USB interfaces; utilizes the second adapter interface 140 to transfer out the COM interface, the VGA interface and the I3C interface, which on the one hand realizes that the ear wing assembly 100 has the function of the above three interfaces, and on the other hand reduces the volume originally occupied by the COM interface, the VGA interface and the I3C interface.

The above-mentioned ear wing module 10, by providing a first adapter interface 130 to transfer out multiple USB interfaces, and a second adapter interface 140 to transfer out COM interfaces, VGA interfaces and I3C interfaces, reduces the volume originally required to be occupied by multiple USB interfaces, COM interfaces, VGA interfaces and I3C interfaces, so that components that originally needed to be distributed on two circuit boards 110 can be integrated into one circuit board 110, thereby forming an ear wing assembly 100 that can meet the needs of the original ear wing module 10, improves the space utilization of the ear wing module 10, and makes the ear wing module 10 have a high degree of integration.

It should be noted that with the continuous development of servers, the new generation of server Intel BHS (Birch Stream) platform needs to support dual-socket, 2x1S configuration, each socket is an independent system, so the new generation of server Intel BHS platform has two independent systems. In order to meet the needs of the two systems, the ear wing module required by the server has two ear wing components with the same structure, each ear wing component has key display, 2 USB ports, VGA port, RJ45 port and other components.

However, the traditional ear-wing module has low space utilization, and the key display, 2 USB ports, VGA port, RJ45 port and other components are divided into two groups and set on two circuit boards, thus forming two groups of ear-wing components with different components, which is difficult to meet the current server development needs.

For this purpose, please refer to FIG. 3 , which is an ear wing module 10 provided by the present application for use in a server with dual systems. In order to meet the requirements of two systems in the new generation of server Intel BHS (Birch Stream) platform, the space utilization rate of the ear wing module 10 is improved. In a preferred implementation, the ear wing module 10 of the present application is used in a server with dual systems, the server includes a front window 20, and the ear wing module 10 includes two ear wing assemblies 100, and the two ear wing assemblies 100 are distributed on both sides of the front window 20. In specific configuration, each ear wing assembly 100 includes a circuit board 110 and a key display 120, a first adapter interface 130 and a second adapter interface 140 arranged on the circuit board 110. The first adapter interface 130 is used to transfer out multiple USB interfaces, and the second adapter interface 140 is used to transfer out a COM interface, a VGA interface and an I3C interface.

The above-mentioned ear wing module 10 replaces the multiple USB interfaces originally directly arranged on the circuit board 110 with the first adapter interface 130, and replaces the COM interface, VGA interface and I3C interface originally directly arranged on the circuit board 110 with the second adapter interface 140, thereby reducing the volume of the circuit board 110 required for the original multiple USB interfaces, COM interfaces, VGA interfaces and I3C interfaces, so that each circuit board 110 has multiple USB interfaces, COM interfaces, VGA interfaces and I3C interface functions, so that an ear wing assembly 100 in the present application is arranged on the left and right sides of the front window 20, so that the two systems in the server can be equipped with an ear wing assembly 100 respectively, and the components of the two ear wing assemblies 100 are the same, so that the ear wing module 10 of the present application meets the needs of a server with two systems.

In order to more conveniently realize the first adapter interface 130 to transfer multiple USB interfaces, in a preferred implementation, the first adapter interface 130 is a Type-C interface. In specific operation, the Type-C interface is transferred to two USB interfaces through an external first adapter. Specifically, one end of the first adapter can be matched with the Type-C interface, and the other end of the first adapter is configured with two USB interfaces. This application uses the Type-C interface to transfer two USB interfaces, which reduces the volume that the original multiple USB interfaces need to occupy, and is conducive to the integration of components that originally need to be distributed on two circuit boards 110 into one circuit board 110.

In order to more conveniently realize the second adapter interface 140 to transfer out the COM interface, VGA interface and I3C interface, in a preferred implementation, the second adapter interface 140 is a Mini-DP interface. In specific operation, the Mini-DP interface is transferred out to the COM interface, VGA interface and I3C interface through an external second adapter. Specifically, one end of the second adapter can be matched with the Mini-DP interface, and the other end of the second adapter is configured with the COM interface, VGA interface and I3C interface. This application uses the Mini-DP interface to transfer out the COM interface, VGA interface and I3C interface, which reduces the volume originally occupied by the COM interface, VGA interface and I3C interface, and facilitates the integration of components that originally need to be distributed on two circuit boards 110 into one circuit board 110.

In order to further reduce the installation space of the key display component 120, the first adapter interface 130 and the second adapter interface 140, it is convenient to set multiple transmission ports for external communication on the same circuit board 110. In a preferred implementation, the key display component 120, the first adapter interface 130 and the second adapter interface 140 are all connected to the circuit board 110 through welding wires.
