[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] Example
[0033] like Figure 1-5As shown, a heat dissipation type KVM switch proposed by an embodiment of the utility model comprises a shell 1, the shell 1 is a U-shaped shell, a slide rail 2 is fixedly connected to the side wall of the shell 1, a cover plate 3 is slidably engaged with the upper end of the slide rail 2, an arc plate 4 is fixedly connected to the cover plate 3, a heat dissipation groove 5 corresponding to the cavity formed by the arc plate 4 and the cover plate 3 is opened on the side of the shell 1, a heat dissipation strip groove 6 is provided on the side of the shell 1, a mounting plate 7 is connected to the side of the shell 1, an interface 8 is provided on the mounting plate 7, a connecting groove 9 is provided on the bottom side wall of the shell 1, a fixing ear 10 is connected to the inside of the shell 1 by bolts, a heat dissipation shell 11 is placed at the back of the shell 1, a heat dissipation plate 12 is plugged into the inside of the heat dissipation shell 11, a handle 13 is provided on the heat dissipation plate 12, and a silent fan 14 is embedded and installed inside the heat dissipation shell 11 on the inner wall of the shell 1; a temperature sensor is installed inside the shell 1, the temperature sensor is electrically connected to the processor, and the processor is electrically connected to the electrical equipment;
[0034] It has a unique U-shaped housing 1, which provides installation space and certain protection;
[0035] The cooperation between the slide rail 2 and the cover plate 3 facilitates the operation and maintenance of the internal structure. The bolt holes have been explained in the application and are not drawn. At the same time, the heat dissipation cavity formed by the arc plate 4 and the heat dissipation groove 5 improves the heat dissipation efficiency;
[0036] Various types of interfaces 8 to meet the connection requirements of different devices;
[0037] The heat dissipation system is mainly composed of a heat dissipation slot 5, a heat dissipation strip slot 6, a heat dissipation shell 11, a heat dissipation plate 12 and a silent fan 14. The heat dissipation slot 5 and the heat dissipation strip slot 6 are distributed on the side of the shell 1, providing a channel for heat dissipation and increasing the heat dissipation area. The heat dissipation shell 11 provides a storage space for heat dissipation components, and the internal heat dissipation plate 12 can further absorb and conduct heat, and accelerate the heat dissipation through its larger surface area. The silent fan 14 accelerates the air flow by actively blowing air, quickly takes away heat, and improves the heat dissipation efficiency. Such a heat dissipation system combination can effectively dissipate the heat generated by the KVM switch when it is working, ensure that the equipment runs stably in a suitable temperature environment, extend the life of the equipment and ensure performance;
[0038] The fixing ear 10 is L-shaped, which is a relatively stable design. It is provided with bolt holes, which are connected and fixed with other components or installation bases by bolts. The height of the fixing ear 10 at the bottom is lower than the installation height of the housing 1. This design can make the KVM switch more stable after installation and will not easily tip over or shake due to the high center of gravity. In actual installation, the fixing ear 10 can be fixed to a suitable position or bracket as needed to ensure that the KVM switch can work safely and reliably. The fixing ear 10 provides an important installation and fixing support point for the entire device;
[0039] like Figure 1 As shown, in some embodiments, the housing 1 is fixedly connected to the mounting plate 7 by bolts at the side, the upper end of the mounting plate 7 is slidably connected to the cover plate 3, and the cover plate 3 is bolted to the mounting plate 7, and the connection position is at the upper end of the mounting plate 7; first, the housing 1 is fixedly connected to the mounting plate 7 at the side by bolts, ensuring the stable installation of the mounting plate 7. In this way, various connectors 8 and other components on the mounting plate 7 can be stably combined with the housing 1.
[0040] Secondly, the upper end of the mounting plate 7 is connected to the cover plate 3 by sliding. This design allows the cover plate 3 to be opened and closed relatively flexibly, making it convenient to operate and maintain the internal structure.
[0041] Finally, the cover plate 3 and the mounting plate 7 are connected at their upper ends by bolts. This further enhances the stability of the connection between the cover plate 3 and the mounting plate 7, while also better maintaining the integrity and stability of the structure. In practical applications, this connection method not only ensures the firmness of the structure, but also has certain operability and flexibility, which is convenient for daily use and maintenance.
[0042] like Figure 1 As shown, in some embodiments, the interface device 8 includes a VGA interface, a DVI interface, an HDMI interface, a USB interface, a PS / 2 interface and a transmission outlet;
[0043] VGA interface: This is a more traditional video interface that transmits analog signals.
[0044] DVI interface: can transmit digital video signals.
[0045] HDMI interface: can transmit high-definition video and audio signals simultaneously.
[0046] USB interface: used to connect input devices such as keyboard and mouse.
[0047] PS / 2 interface: also used to connect keyboard and mouse.
[0048] like Figure 3As shown, in some embodiments, the fixing ear 10 is L-shaped and has bolt holes, and the bottom of the fixing ear 10 is lower than the installation height of the housing 1; the fixing ear 10 is designed to be L-shaped, which is a common and practical shape. One side of the L-shaped can be used to connect and fix with the housing 1, usually by welding or other fastening methods; the other side is perpendicular to the housing 1 and is used to fix with the installation base or other supporting structure.
[0049] Bolt holes are provided on the fixing ear 10 for fastening it with other components by bolts. Bolt connection has the advantages of high reliability and convenient installation and disassembly.
[0050] It is worth noting that the height of the fixing ear 10 at the bottom is lower than the installation height of the housing 1. This design has several advantages: first, it can lower the center of gravity of the entire device, making the device more stable after installation and less likely to tip over or shake due to external forces; second, it can allow the device to better fit the installation base during installation, increase the contact area, and improve stability; third, in some specific scenarios, this fixing ear 10 that is lower than the installation height of the housing 1 may be more conducive to coordinated installation with other devices or structures to achieve overall coordination and stability, and the installation hole position can be opened at any position to facilitate bottom heat dissipation.
[0051] like Figure 4 As shown, in some embodiments, the heat dissipation slots 5, heat dissipation strip slots 6, connection slots 9 and heat dissipation plates 12 are covered with dustproof nets; the dustproof nets can effectively prevent external dust, impurities, etc. from entering these heat dissipation structures. If there is no dustproof net, dust and the like may accumulate in the heat dissipation slots 5, heat dissipation plates 12 and other parts over a long period of time, affecting the heat dissipation effect, and may even cause the heat dissipation channel to be blocked, thereby affecting the normal operation and performance of the device.
[0052] With a dust screen, the normal circulation of air can be ensured to achieve heat dissipation, and the intrusion of dust can be reduced to keep the inside of the device clean. This can extend the service life of the device and reduce failures and maintenance costs caused by dust accumulation. At the same time, the dust screen usually has a certain degree of air permeability and filtering properties. While playing a dust-proof role, it will not have a significant negative impact on the heat dissipation efficiency.
[0053] In some embodiments, the processor is electrically connected to the output transmission rate sensor, and the temperature sensor is used to monitor the temperature inside the device in real time. When the temperature reaches a certain threshold, the speed of the silent fan 14 is automatically adjusted, for example, when the temperature is low, the speed is reduced to reduce noise and energy consumption, and when the temperature is high, the speed is increased to enhance the heat dissipation effect; more accurate and efficient intelligent heat dissipation can be achieved to ensure that the device can maintain good working conditions and performance under various conditions; at the same time, the data transmission rate sensor is connected in parallel with the interface 8, which can feedback the transmission performance of the network or data channel in real time, help to timely discover transmission bottlenecks or abnormal conditions, and feedback to the processor, and the processor can transmit the information to the display.
[0054] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
