[0103] With the development of information technology, enterprises' demands for information transmission are becoming more and more diversified, and the network is carrying more and more data and equipment terminals. However, this also brings about the problem of complex deployment and difficult maintenance of data equipment.

[0104] In an application scenario involved in the present application, for example, in a modern enterprise, the types of services carried by network equipment include data services, voice services, multicast services, and broadcast services. Equipment involved in data services include personal computers, printers, access points, monitoring, information equipment, etc., equipment involved in voice services include IP phones, traditional phones, etc., and equipment for multicast services or broadcast services includes information publishing systems, display screens, etc. Therefore, there are many types of equipment for building enterprise network services, such as switching equipment, routing equipment, security equipment, storage equipment, etc. However, for small and medium-sized enterprises, configuring the above-mentioned network equipment at the same time is complicated and requires the configuration of special cabinets to achieve deployment; in addition, managing multiple network devices at the same time also poses maintenance difficulties.

[0105] To address the complex deployment of multiple network devices, related technologies use rack-mounted switches combined with routers, enabling both switching and routing functions within an enterprise. However, this approach results in an overly large chassis, occupying significant space and creating a non-compact structure. Furthermore, the devices only provide switching and routing functions and are unable to carry other services, resulting in poor applicability.

[0106] The transmission assembly of a switch in the related art requires multiple components that electrically connect to the power supply unit 600, line card unit 700, management card unit 800, and fixed card unit 900 to achieve electrical connection or signal transmission. This complicates the internal structure of the switch. Furthermore, the multiple components in the transmission assembly increase the number of components in the switch, which can also reduce the reliability of the switch.

[0107] In the transmission component proposed in the embodiment of the present application, multiple line card interfaces on the connection part are electrically connected to the switching matrix part (for example, a forwarding engine (FE) card), so that multiple line cards can be connected to the connection part, and multiple power supply interfaces opened on the connection part are electrically connected to the switching matrix part, so that multiple external power supplies can be electrically connected to the switching matrix part through the multiple power supply interfaces, thereby powering the switching matrix part and the line cards connected to the multiple line card interfaces.

[0108] The multiple power interfaces include at least one low-voltage interface and at least one high-voltage interface. The low-voltage interface is used to connect to a low-voltage power source, and the high-voltage interface is used to connect to a high-voltage power source. This allows both the high-voltage and low-voltage power sources to be connected to the connection unit, thereby providing both low-voltage and high-voltage power to the switch matrix unit and multiple line cards.

[0109] The multiple line card interfaces include at least one high-speed interface and at least one low-speed interface. The high-speed interface is used to connect to the low-speed line card, and the low-speed interface is used to connect to the high-speed line card, so that both the low-speed line card and the high-speed line card can be electrically connected to the switching matrix unit through the connection portion. This allows the transmission component of the present application to be installed with a larger number of external power supplies and line cards, and can support different types of power supplies and line cards with different functions. The connection of line cards with different functions to the connection portion allows the transmission component of the exemplary embodiment of the present application to implement multiple business functions, thereby making the transmission component of the exemplary embodiment of the present application more applicable and more integrated.

[0110] The transmission component provided in this application is described in detail below with reference to specific embodiments.

[0111] Referring to Figure 1 , an embodiment of the present application provides a switch comprising a transmission assembly, a power supply unit 600, a line card unit 700, a management card unit 800, and a fixed card unit 900. The power supply unit 600, the line card unit 700, the management card unit 800, and the fixed card unit 900 are all electrically connected to the transmission assembly. The power supply unit 600 can power electrical components within the transmission assembly and can also power the line card unit 700, the management card unit 800, and the fixed card unit 900 via the transmission assembly.

[0112] 2-4 , an embodiment of the present application further proposes a transmission component, including a housing 100 , a switching matrix portion 200 , and a connection portion 300 . The transmission component can be applied to the switch of the embodiment of the present application.

[0113] Among them, the shell 100 is the basic component of the transmission component of the present application. The shell 100 can provide an installation base for at least some of the other components of the transmission component, and can also play a role in protecting at least some of the other components of the transmission component. The material of the shell 100 can be metal or composite material. When the material of the shell 100 is metal, the shell 100 has better structural strength. At the same time, because the metal material has good thermal conductivity, the heat generated by the components in the shell 100 is also easier to dissipate outward through the shell 100. When the shell 100 is made of a composite material, the weight of the shell 100 is relatively light, which makes the overall weight of the transmission component and the switch using the transmission component relatively light. In the embodiment of the present application, there is no limitation on the specific material of the shell 100.

[0114] The housing 100 defines a cavity, and the switch matrix unit 200 is disposed within the cavity. The switch matrix unit 200 is the core component for data transmission and exchange in the transmission assembly of the embodiment of the present application, and is also the core component for data transmission and exchange in the switch of the embodiment of the present application. The switch matrix unit 200 is used to implement point-to-point connections between line cards and provides packet forwarding between these point-to-point line cards. Other components of the switch can be electrically connected to the switch matrix unit 200 to enable data communication between them.

[0115] The connecting part 300 can also be set in the shell 100. The connecting part 300 is used to connect components such as the switching matrix part 200, the power supply part 600, the line card part 700, the management card part 800 and the fixed card part 900, and realize electrical connection and communication connection between each component through the connecting part 300.

[0116] 1 , the connection unit 300 is only connected to the switch matrix 200, the power supply unit 600, and the line card unit 700. It should be noted that in other embodiments of the present application, the connection unit 300 may also be connected to the management card unit 800 and the fixed card unit 900.

[0117] The connection portion 300 may be provided with at least one power interface 310 and a plurality of line card interfaces 320 .

[0118] In the embodiment shown in Figure 1, the number of at least one power interface 310 is 2. Those skilled in the art should understand that the embodiment of the present application does not limit the number of power interfaces 310, and the number of power interfaces 310 can also be 3, 4, or 5.

[0119] In some implementations, when the switch does not need to supply external power, the number of the power interface 310 may be one. By providing only one power interface, the volume of the transmission component and the switch can be reduced.

[0120] In some embodiments, when the switch needs to be powered externally, or the switch has complex functions and requires multiple different power sources, the number of power supply interfaces 310 can be multiple, and multiple power supply interfaces 310 can be respectively connected to multiple power supply units 600 to power the switch and other devices connected to the switch.

[0121] Each of the multiple power supply interfaces 310 can be electrically connected to the switch matrix unit 200. When the switch of the embodiment of the present application has multiple power supply units 600, the multiple power supply units 600 can be electrically connected to the switch matrix unit 200 via the multiple power supply interfaces 310, so that the multiple power supply units 600 can provide power to the switch matrix unit 200. As will be appreciated by those skilled in the art, the multiple power supply units 600 can also directly provide power to components connected to the connection unit 300 through the connection unit 300.

[0122] The multiple line card interfaces 320 on the connection part 300 can be used for plugging in multiple line card parts 700. When the number of line card parts 700 of the switch of this application is also multiple, the multiple line card parts 700 can be electrically connected to the switching matrix part 200 through the multiple line card interfaces 320.

[0123] The transmission component provided in the embodiment of the present application can be installed with at least one power supply unit 600 and multiple line card units 700, and is suitable for more application scenarios. Specifically, the transmission component can be connected by connecting multiple line card units 700 that can realize different functions to the multiple line card interfaces 320 of the connection unit 300, so that the transmission component of the present application can have multiple different business functions, thereby realizing multi-business carrying. It can be understood by those skilled in the art that the functions of the line card unit 700 can include different functions such as switching and routing. By plugging in line card units 700 with different functions, multi-business functions can be realized. Compared with the solution of stacking switching equipment and routing equipment in the related art, the transmission component and switch provided in the embodiment of the present application can realize the switching and routing functions in the same device at the same time, effectively reducing the size of the device and reducing the maintenance cost of the device. Therefore, the switch of the embodiment of the present application is smaller in size and has richer functions. The multiple line card units 700 can respectively implement a variety of different functions. In addition to the line card units 700 with different functions such as switching and routing mentioned above, the multiple line card units 700 in the embodiment of the present application can include line card units 700 with data auditing, data monitoring, and data analysis functions, so that the switch of the embodiment of the present application can have functions such as data auditing, data monitoring, and data analysis. In addition, through the transmission components provided in the embodiment of the present application, line card units 700 with different functions can be set to implement a variety of different functions. Compared with the line card units 700 with a single function in the related art, the transmission components provided in the embodiment of the present application can implement a variety of different functions and can be flexibly set to suit different application scenarios.

[0124] A power slot 110 and a line card slot 120 are defined in the housing 100 . When the power supply unit 600 and the line card unit 700 are connected to the connecting unit 300 , the power supply unit 600 is located in the power slot 110 , and the line card unit 700 is located in the line card slot 120 .

[0125] When the transmission component includes multiple power interfaces 310, the multiple power interfaces 310 include at least one high-voltage interface 310A and at least one low-voltage interface 310B, wherein the high-voltage interface 310A can be matched with the high-voltage power supply unit 600, so that the high-voltage power supply unit 600 can be electrically connected to the switch matrix unit 200 through the high-voltage interface 310A. In some embodiments, after the high-voltage power supply unit 600 is electrically connected to the switch matrix unit 200 through the high-voltage interface 310A, high-voltage electricity can be input to the switch matrix unit 200, so that the high-voltage electricity can also be input to other devices that require high-voltage power supply through the switch matrix unit 200, such as devices that supply power to the outside. In other embodiments, the high-voltage power supply unit 600 is connected to the connection unit 300 through the high-voltage interface 310A, the connection unit 300 is connected to the external device, and the high-voltage power supply unit 600 supplies power to the external device through the connection unit 300. The external device may include an access point (AP), a camera, and other devices. When supplying power, the high-voltage power supply unit 600 can directly supply power to external devices, or it can supply power to external devices through Power over Ethernet (PoE). After the low-voltage power supply unit 600 is electrically connected to the switching matrix unit 200 through the low-voltage interface 310B, low-voltage electricity is input to the switching matrix unit 200. In this way, the low-voltage electricity can also be input to other devices that require low-voltage power supply through the switching matrix unit 200, such as devices that directly use electricity without external power supply. The low-voltage power supply unit 600 is connected to the line card through the low-voltage interface 310B, and the low-voltage power supply unit 600 can directly supply power to the line card through the connection unit 300. In this embodiment, the transmission component is provided with both the high-voltage interface 310A and the low-voltage interface 310B, so that the transmission component of the embodiment of the present application and the switch using the transmission component can be installed with components with different voltage requirements, thereby improving the applicability of the transmission component. It can be understood by those skilled in the art that high-voltage electricity is mainly used to provide power, and the power provided by the high voltage allows the normal operation of electrical appliances. Low-voltage electricity is mainly used to provide signals, and the signals provided by low-voltage electricity can be understood as information such as sound, data, and images. Generally speaking, high-voltage electricity can operate independently, while low-voltage electricity generally cannot operate independently. The difference between high-voltage electricity and low-voltage electricity depends not only on the size of the voltage, but also on the purpose. For APs in the communications field, voltages greater than 36V are called high-voltage electricity, and voltages less than or equal to 12V are called low-voltage electricity. High-voltage electricity includes both strong AC power, such as 220V AC, and 48V DC power supplied by PoE. Of course, different manufacturers can also make settings for high-voltage electricity and low-voltage electricity according to different needs, and the embodiments of this application do not impose any special limitations.

[0126] The multiple line card interfaces 320 include at least one high-speed interface 320A and at least one low-speed interface 320B. The high-speed interface 320A can be paired with a high-speed line card unit 700, allowing the high-speed line card unit 700 to be electrically connected to the switch matrix unit 200 via the high-speed interface 320A. Those skilled in the art will appreciate that the high-speed line card unit 700 can include line cards that provide uplink functionality and line cards used to expand high-bandwidth devices such as servers. After the low-speed line card unit 700 is electrically connected to the switch matrix unit 200 via the low-speed interface 320B, the low-speed line card unit 700 can be electrically connected to the switch matrix unit 200 via the low-speed interface 320B. Those skilled in the art will appreciate that the low-speed line card unit 700 can include a low-bandwidth line card that provides downlink functionality. The transmission component provided in this embodiment of the present application, by providing both a high-speed interface 320A and a low-speed interface 320B, can accommodate components with different transmission speed requirements, thereby improving the adaptability of the transmission component. Those skilled in the art will appreciate that a signal transmission rate less than 1 Gbps is referred to as low speed, and a signal rate greater than or equal to 1 Gbps is referred to as high speed. Of course, different equipment manufacturers may define high speed and low speed signal rates based on actual scenarios, and the present application does not impose any particular limitations thereon.

[0127] In some embodiments, referring to FIG1 , in order to electrically connect the power interface 310 and the line card interface 320 of the connection portion 300 in the embodiment of the present application to the switch matrix portion 200, a connection terminal 230 is provided on the connection portion 300. The connection terminal 230 of the connection portion 300 is electrically connected to the switch matrix portion 200, thereby enabling the power interface 310 and the line card interface 320 to be electrically connected to the switch matrix portion 200 via the connection terminal 230. As will be appreciated by those skilled in the art, the connection portion 300 may further include a printed circuit board (PCB) for achieving electrical connections between different interfaces. For example, the connection between the power interface 310 and the line card interface 320, the connection between the power interface 310 and the connection terminal 230, or the connection between the line card interface 320 and the connection terminal 230 may be achieved via the PCB.

[0128] It should be understood that electronic components, such as the line card unit 700 and the switch matrix unit 200, generate heat during operation. If this heat cannot be dissipated promptly, it will affect the stability of the electronic components' operation and may even damage them. Continuing with Figure 1 , to prevent heat concentration in the transmission component and the switch in which it is used during operation, the power interface 310 and the line card interface 320 of the connection unit 300 can be located on the same side of the connection unit 300. The connection end 230, the power interface 310, and the line card interface 320 are all arranged opposite to each other relative to the connection portion 300. Accordingly, the switch matrix portion 200 can also be arranged adjacent to the connection end 230, so that the switch matrix portion 200, the power interface 310, and the line card interface 320 are also distributed on opposite sides of the connection portion 300. In this way, the heat generated by the switch matrix portion 200 is concentrated on one side of the connection portion 300, and the heat generated by the power supply portion 600 and the line card portion 700 is concentrated on the other side of the connection portion 300. As a result, the connection portion 300 isolates the heat within the transmission component, making the heat relatively dispersed, thereby preventing local overheating of the transmission component. The transmission component in the embodiment of the present application can prevent localized heat accumulation through reasonable partitioning. As those skilled in the art will understand, the power supply portion 600 generates a lot of heat, and a separate fan can be provided to dissipate the heat from the power supply portion 600. The main heat of the line card part 700 is generated by the line card processing part during operation. Therefore, the line card processing part and the switching matrix part 200 can be distributed on opposite sides of the connection part 300. Accordingly, the line card processing part is set on the same side as the power interface 310 and the line card interface 320. In this way, the heat generated by the line card processing part and the switching matrix part 200 can be dispersed in different areas within the shell 100. At the same time, the line card processing part can also be set adjacent to the line card interface 320 to make the signal transmission between the line card processing part and the line card interface 320 more stable.

[0129] In some embodiments, referring to Figures 1 and 2, the switching matrix unit 200 of the present application may be provided with a management interface 210 and a fixed interface 220, wherein the management interface 210 may be used to connect to the management card unit 800, so that the management card unit 800 can be electrically connected to the switching matrix unit 200, and a chip may be provided in the management card unit 800, so that the management card unit 800 can implement functions such as routing protocol processing and security auditing. The fixed interface 220 may be used to connect to the fixed card unit 900, and the fixed card unit 900 is fixedly connected to the housing 100, and the fixed card unit 900 can be used to implement fixed business functions. Specifically, the fixed business functions include host control of the transmission component, communication with external devices, and data import and export of internal storage devices. It can be understood by those skilled in the art that the fixed card unit 900 is used to implement the management function of the entire machine, and therefore, the fixed card unit 900 can be fixedly set on the transmission component and then fixedly connected to the switch.

[0130] In some embodiments, the management card unit 800 is directly connected to the switch matrix unit 200 via the management interface 210, and the fixed card unit 900 is directly connected to the switch matrix unit 200 via the fixed interface 220. When the switch matrix unit 200 is directly connected to the management card unit 800 and the fixed card unit 900, the switch matrix unit 200 transmits signals directly through the management interface 210 and the fixed interface 220, without the need for other transfer components, thereby reducing signal transmission attenuation. A management card slot 130 and a fixed card slot 140 are also provided in the housing 100. When the management card unit 800 and the fixed card unit 900 are connected to the switch matrix unit 200, the management card unit 800 is located in the management card slot 130, and the fixed card unit 900 is located in the fixed card slot 140.

[0131] Specifically, the number of management interfaces 210 can be multiple, and accordingly, the number of management card units 800 can also be multiple, and multiple management card units 800 can be plugged into multiple management interfaces 210. The multiple management card units 800 can adopt different models and forms, so that the multiple management card units 800 can implement different functions. The fixed card unit 900 connected to the fixed port of the switching matrix unit 200 can be provided with a device management port, such as a Universal Serial Bus (USB) and a console CONSLE interface. In this way, the interfaces on the fixed card unit 900 can be used to log in to operate the device, configure and manage the device, and update the device software system.

[0132] The management interface 210, the line card interface 320, and the power interface 310 are located on the same side of the switch matrix unit 200, while the fixed interface 220 and the management interface 210 are located on different sides of the switch matrix unit 200. This allows the multiple interfaces on the switch matrix unit 200 to be relatively dispersed. For example, as shown in FIG1 , the fixed interface 220 can be located on the right side of the switch matrix unit 200, while the management interface 210 can be located on the bottom side of the switch matrix unit 200. In other embodiments, the fixed interface 220 can also be located on the top side of the switch matrix unit 200, while the management interface 210 can be located on the bottom side of the switch matrix unit 200.

[0133] In some embodiments, referring to Figures 4 to 6, in order to efficiently dissipate the internal heat of the transmission component of the present application during operation, reduce the temperature inside the housing 100, and protect the components inside the housing 100, the transmission component of the present application may also be provided with a fan 400, and an air inlet 150 and an air outlet 160 may be provided on the housing 100. The air inlet 150 and the air outlet 160 of the housing 100 are opened on the surface of the housing 100, and the air inlet 150 and the air outlet 160 are connected to the cavity inside the housing 100 for accommodating the switching matrix part 200, the connection part 300, the power supply part 600, the line card part 700, the management card part 800, and the fixed card part 900. The fan 400 can be set at the air inlet 150 or the air outlet 160 of the shell 100. The fan 400 can suck in cold air from the outside of the shell 100, so that the cold air can come into contact with the hot air and heat-generating components in the shell 100 for heat exchange. Then the fan 400 discharges the heat-exchanged air through the air outlet 160 of the shell 100, so that the heat in the shell 100 can be efficiently dissipated to the outside of the shell 100.

[0134] The connection portion 300 of the present application can be a sheet-like structure, and the connection portion 300 can be vertically arranged within the housing 100. In some implementations, the connection portion 300 can be a PCB board, and the sheet-like structure can be understood as the plate-like structure of the PCB board. Specifically, when the connection portion 300 is vertically arranged within the housing 100, the bottom end of the connection portion 300 is connected to the bottom wall of the housing 100, and the top end of the connection portion 300 is connected to the top wall of the housing 100. Accordingly, the power interface 310 and the line card interface 320 of the connection portion 300 are arranged on the side of the connection portion 300 facing the power supply unit 600 and the line card unit 700, and the connection end 230 of the connection portion 300 is arranged on the side of the connection portion 300 facing the switch matrix unit 200. A gap is provided between the top end of the connection portion 300 and the top wall of the housing 100, and the gap allows air to pass through. The air inlet 150 and air outlet 160 of the housing 100 can be arranged on both sides of the housing 100, with the air inlet 150 and air outlet 160 located on opposite sides of the connection portion 300. That is, one of the air inlet 150 and air outlet 160 is located on the line card portion 600 side, and the other is located on the switch matrix 200 side. In this way, air entering the housing 100 through the air inlet 150 can pass through the gap between the top of the connection portion 300 and the top inner wall of the housing 100 and be discharged through the air outlet 160 of the housing 100. It should be understood that the density of hot air is lower than that of cold air. Therefore, the air heated by the switch matrix unit 200, line card unit 700, power supply unit 600, management card unit 800, and fixed card unit 900 in the housing 100 will spontaneously concentrate in the upper area of ​​the housing 100. Thus, when the fan 400 is activated, the hot air can pass directly through the gap between the connection unit 300 and the top inner wall of the housing 100, allowing the hot air to pass through the housing 100 more efficiently and be discharged from the air outlet 160 of the housing 100. In this embodiment, the bottom of the housing 100 is provided with heat-generating components such as the switch matrix unit 200, line card unit 700, power supply unit 600, management card unit 800, and fixed card unit 900. When hot air is generated, a hot air flow is formed. Due to its lower density, the hot air flow moves upward quickly, thereby increasing the flow rate of the hot air.

[0135] In some embodiments, referring to FIG6 , at least a portion of the air inlet 150 and at least a portion of the air outlet 160 of the present application can be positioned opposite the gap between the connection portion 300 and the top inner wall of the housing 100, thereby allowing the air inlet 150, the air outlet 160, and the gap between the connection portion 300 and the top inner wall of the housing 100 to form a convection channel. This allows heat within the housing 100 to be more efficiently dissipated from the housing 100. Furthermore, a portion of the air inlet 150 can also be positioned opposite the line card portion 700, the power supply portion 600, the fixing card portion 900, and the management card portion 800. This allows the cold air entering the housing 100 through the air inlet 150 to fully engage in heat exchange with the line card portion 700, thereby improving the heat dissipation effect of the line card portion 700. In this embodiment, because some air inlets 150 are opposite the line clamp portion 700, the fixed clamp portion 900, and the management clamp portion 800, when the hot air generated by these components flows upward, its pressure decreases, creating a pressure difference with the external cold air. This accelerates the movement of the cold air and improves heat dissipation efficiency. In this embodiment of the present application, by providing a heat dissipation duct with mixed high and low pressure flow, air flow can be accelerated. In this case, even if the speed of the fan 400 is reduced, the heat dissipation effect can be achieved, thereby reducing the power of the entire machine, achieving energy saving and noise reduction.

[0136] In some embodiments, in the transmission component of the present application, referring to Figures 2 and 3, the shell 100 may be provided with a plug interface 170. When the power supply unit 600, the line card unit 700, the management card unit 800 and the fixed card unit 900 are installed in the shell 100 and are respectively connected to the connection unit 300 and the switching matrix unit 200, the interfaces of the power supply unit 600, the line card unit 700, the management card unit 800 and the fixed card unit 900 themselves may be located at the plug interface 170, so that the interfaces of the power supply unit 600, the line card unit 700, the management card unit 800 and the fixed card unit 900 themselves may be exposed on the surface of the shell 100, so that external components can be conveniently connected to the power supply unit 600, the line card unit 700, the management card unit 800 and the fixed card unit 900.

[0137] In the related solution, a hard disk assembly is also provided in the switch. As shown in FIG4 and FIG11, the hard disk is installed along the third direction, that is, the hard disk interface is provided in the switching matrix portion, and the position of the hard disk interface is parallel to the connection portion. If the side provided with the cable card slot is defined as the first side of the shell, and the side opposite to the first side is defined as the second side, then the hard disk interface in the related art is provided toward the second side. At this time, if the hard disk 540 shown in FIG8-10 is to be installed, because the hard disk 540 is longer in the depth direction, the depth of the transmission component and the switch will be increased, thereby increasing the volume of the transmission component and the switch.

[0138] In some embodiments, referring to Figures 4 and 9, the transmission assembly provided by the exemplary embodiments of the present application may further include a hard disk carrier 500. The hard disk carrier 500 may be disposed within the housing 100 and movably connected to the housing 100. The hard disk carrier 500 is provided with a hard disk receiving position for supporting and mounting a hard disk 540. When the hard disk 540 is mounted on the hard disk carrier 500, the hard disk 540 is fixed to the hard disk carrier 500. The switching matrix unit 200 is also provided with a hard disk interface 240. The hard disk interface 240 is located within the housing 100 and is electrically connected to the switching matrix unit 200. The hard disk interface 240 cooperates with the hard disk 540, and the hard disk 540 can be plugged into the hard disk interface 240, thereby electrically connecting the hard disk 540 to the switching matrix unit 200. In this embodiment, the hard disk carrier 500 is configured to be movable toward or away from the hard disk interface 240. That is, the hard disk receiving position of the hard disk carrier 500 can be moved toward or away from the switching matrix unit 200. When the hard disk carrier 500 moves toward the hard disk interface 240, the hard disk 540 mounted on the hard disk carrier 500 can also move with the hard disk carrier 500 toward the hard disk interface 240, so that the interface on the hard disk 540 can be plugged into the hard disk interface 240 in the housing 100. When the hard disk carrier 500 moves away from the hard disk interface 240, the hard disk 540 mounted on the hard disk carrier 500 can also move with the hard disk carrier 500 away from the hard disk interface 240, so that the interface on the hard disk 540 can be separated from the hard disk interface 240 in the housing 100.

[0139] The hard disk 540 is detachably connected to the hard disk carrier 500, so that the hard disk 540 set on the hard disk carrier 500 can be removed and replaced. In this way, when the data in the hard disk is fully stored, the hard disk carrier 500 can be driven to move, so that the hard disk 540 with full data storage can be separated from the hard disk interface 240 and the hard disk 540 can be replaced.

[0140] In some embodiments, referring to Figures 7, 8, 9, and 10, the hard disk support portion 500 of the present application may specifically include a support base 510, a hard disk fixing member 520, and a drive member 530, wherein the hard disk support position is set on the hard disk fixing member 520, so that the hard disk fixing member 520 can be used to support and fix the hard disk 540, the hard disk fixing member 520 can be movably connected to the support base 510, and the drive member 530 is connected to the hard disk fixing member 520, and the drive member 530 is configured to be driven to rotate in a first direction or a second direction that are opposite to each other. Referring to Figure 9, when the drive member 530 rotates in the first direction, the hard disk fixing member 520 can be moved toward the hard disk interface 240 of the switching matrix unit 200, so that the hard disk 540 fixed to the hard disk fixing member 520 can move toward the hard disk interface 240, so that the hard disk 540 is docked with the hard disk interface 240. When the driving member 530 rotates in a second direction opposite to the first direction, the hard disk fixing member 520 can move away from the hard disk interface 240 in the housing 100, so that the hard disk 540 fixed to the hard disk fixing member 520 can move away from the hard disk interface 240 to separate the hard disk 540 from the hard disk interface 240.

[0141] Specifically, the driving member 530 may include a handle 531 and a slider 532, wherein the handle 531 is rotatably connected to the supporting base 510, and one end of the handle 531 is also rotatably connected to the slider 532. The rotational connection between the handle 531 and the slider 532 and the rotational connection between the handle 531 and the supporting base 510 are staggered, so that the part where the handle 531 is connected to the supporting base 510 is different from the part where the handle 531 is connected to the slider 532. The slider 532 is connected to the hard disk fixing member 520, and the supporting base 510 is provided with a slide groove 511. The extension direction of the slide groove 511 is set in the same direction as the direction of the hard disk fixing member 520 toward the hard disk interface 240. Part of the slider 532 can be embedded in the slide groove 511, so that the slider 532 can move along the slide groove 511. In this way, when the handle 531 is driven to rotate, the slider 532 can be driven to move along the slide groove 511, so that the hard disk fixing component 520 connected to the slider 532 can move along the extension direction of the slide groove 511, and then the hard disk fixing component 520 can move toward the hard disk interface 240 or move away from the hard disk interface 240, so that the hard disk can be connected to or separated from the hard disk interface 240.

[0142] Specifically, referring to FIG. 11 , FIG. 11 shows, from left to right, the first, second, and third states of the hard disk 540, respectively, illustrating the process of adjusting the hard disk 540 from docking with the hard disk interface 240 to detaching from the hard disk interface 240. When the hard disk 540 is in the first state, it is docked with the hard disk interface 240. By rotating the handle 531 in the second direction, the hard disk 540 can be adjusted to the second state, in which the hard disk 540 is detached from the hard disk interface 240. As the handle 531 continues to rotate in the second direction, the hard disk 540 can be adjusted to the third state, in which the distance between the hard disk 540 and the hard disk interface 240 continues to increase, making it easier for the user to ultimately remove the hard disk 540 from the supporting base 510. To dock the hard disk 540 with the hard disk interface 240, the hard disk 540 can be adjusted from the third state to the second state, and finally to the first state.

[0143] The hard disk fixture 520 can be specifically a frame structure, and the hard disk 540 can be placed inside the hard disk fixture 520. The hard disk fixture 520 can have screw holes corresponding to the screw holes on the hard disk 540, so that the hard disk 540 can be fixed to the hard disk fixture 520 via bolts. The supporting base 510 can also be configured as a frame structure, and the hard disk fixture 520 can be disposed inside the supporting base 510 so that the hard disk 540 can also be located inside the supporting base 510. In this way, the supporting base 510 can serve the purpose of protecting the hard disk 540.

[0144] The housing 100 may also include a hard drive opening. The hard drive opening is formed on the surface of the housing 100 and communicates with the cavity within the housing 100. The hard drive carrier 500 can be placed into or removed from the housing 100 through the hard drive opening to facilitate replacement of the hard drive 540. When the hard drive carrier 500 is located within the housing 100, at least a portion of the handle 531 is located outside the housing 100, allowing the user to conveniently rotate the handle 531 to connect or disconnect the hard drive 540 from the hard drive interface 240. Specifically, referring to FIG9 , the hard drive 540 is located within the hard drive carrier 500 and can be connected to the hard drive interface 240; referring to FIG10 , the hard drive 540 is located within the hard drive carrier 500 and can be disconnected from the hard drive interface 240.

[0145] In this embodiment, the hard drive 540 is installed along the fourth direction, that is, the hard drive interface is provided on the switch matrix portion 200, and the hard drive interface 240 is positioned perpendicular to the connection portion. This embodiment can effectively reduce the depth of the transmission components and switches, increase the compactness of the layout, and reduce the size of the device.

[0146] Finally, it should be noted that the above implementation modes are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned implementation modes, ordinary technicians in this field should understand that they can still modify the technical solutions described in the aforementioned implementation modes, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation modes of the present application.
