Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the range of protection of the utility model.

[0035] KVM is based on multi-host switching technology, and switching between multiple servers is completed with the help of a set of keyboard or mouse and display, thereby saving space, reducing cost, making management more simple and convenient, and improving work efficiency.

[0036] At present, there are many products with different interfaces under the KVM category, and the more common one is the KVM switch form, which is inputting a video and keyboard signal, and through the key, the signal can be switched to multiple video output signals and keyboard output signals, achieving the purpose of controlling multiple terminal devices with one display and one set of keyboard and mouse. Under the KVM category, there is also a form of subdividing the scene by transmitting signals through the network. This form inputs Ethernet network cable, and outputs video signal and keyboard signal. The use scene of this form is that the user can control the KVM device in the local area network through the browser and network signal, and the KVM device controls the terminal, so as to achieve the purpose that the user accesses multiple terminals through the network. This form can overcome the line distance limitation of the KVM switch form. Under this form, the control distance becomes the distance of the network cable, so the control range is greatly increased, and the controllable devices are also greatly increased.

[0037] However, the current KVM products are relatively large in size, and when the customer application scene space is relatively compact, the product will obviously have more space occupation.

[0040] Considering that the current KVM products use fans for cooling, which will continuously emit noise and are not suitable for working in a quiet environment, in the present embodiment, the bottom surface of the shell 10 is provided with heat dissipation fins 14, which dissipate heat, and almost no noise is generated during heat dissipation, so that the multi-computer switch can work in a quiet environment.

[0041] Preferably, the bottom surface of the shell 10 is also provided with foot pads 15, which are distributed around the heat dissipation fins 14, and the arrangement of the foot pads 15 enables the multi-computer switch to be stably supported.

[0042] The first board card 2, HDMI-to-MIPI module 3 and second board card are arranged inside the shell 10, and the first board card 2, HDMI-to-MIPI module 3 and second board card are arranged in a stack from bottom to top. Unlike the current KVM products which use a whole PCB design and have interfaces distributed in a parallel line, this design will result in a relatively large KVM product, and the multi-computer switch uses a three-board card stack solution, i.e., the first board card 2, HDMI-to-MIPI module 3 and second board card, and each PCB also has some interfaces allocated, which makes the overall volume of the whole machine smaller and almost no space is wasted.

[0043] Specifically, the first board card 2 is an RV Nano core board, which is provided with a core processor, one end of the first board card 2 is provided with a USB HID interface 21, and the other end of the first board card 2 is provided with a network port 22, which can be an RJ45 hundred-megabit network port, the USB HID interface 21 and the network port 22 are electrically connected with the core processor; the HDMI to MIPI module 3 is provided with a dedicated HDMI to MIPI chip, and the HDMI to MIPI module 3 is provided with an HDMI input interface 31, that is, an HDMI female port, the HDMI input interface 31 and the HDMI to MIPI chip are electrically connected with the core processor, and the HDMI to MIPI dedicated chip can convert the HDMI signal, convert the HDMI signal into the MIPI signal and transmit the MIPI signal to the core processor; the second board card is a KVM-A card, in the embodiment, the display screen 11, the control button 12 and the indicator light 13 are all arranged on the second board card, one end of the second board card is provided with a first USB-C interface 41, the first USB-C interface 41 is an interface controlled by an ATX power supply, which is used for connecting with an external power supply, and the other end of the second board card is provided with a second USB-C interface 42, which is used for connecting with an I / O circuit board.

[0044] In addition, the second board card is also provided with a plurality of debugging interfaces 43 for debugging and testing, and it can be understood that the debugging interfaces 43 are electrically connected with the core controller.

[0048] In the embodiment, the multi-computer switch further comprises an externally matched third board card 5 which is selected according to the needs of users and specific use scenarios; one end of the third board card 5 is provided with a third USB-C interface 51 which is used for electrical connection with the second USB-C interface 42, so that the third board card 5 can be connected with the second board card, and the other end of the third board card 5 is provided with a pin interface 54 which is used for connecting computer ATX pins and is used for remote on-off of the computer, and the third board card 5 is further provided with a relay 53 which is used for controlling the on-off signal, and the third board card 5 is electrically connected with the core processor after being connected with the second board card.

[0049] The third board card 5 is a KVM-B board, and optionally, the computer is first connected with the third board card 5, the wire body in the computer case is connected, and then the third board card 5 is connected with the second board card, so as to provide the function of remote control as the host external hardware.
