Description

Technical Field

[0001] This utility model relates to the field of digital extenders, specifically a single-screen digital extender with dual network cable extension. Background Technology

[0002] A single-screen digital extender, especially a single-screen KVM (Keyboard, Video, Mouse) extender, is a device that can remotely transmit video, keyboard, mouse, and other signals from a computer host (or other signal source) to another end. The single-screen digital extender digitizes the signal from the signal source via a network or dedicated cable (such as a CAT5E / CAT6 network cable) and transmits it remotely to the receiving end. The receiving end then restores the received digital signal to the original video, keyboard, mouse, and other signals, thereby enabling operation and control of the remote device.

[0003] In the current digital extender market, the difficulty in disassembling and assembling the casing is a significant problem, causing considerable inconvenience for users. Specifically, traditional digital extenders typically use screws or welding to connect the casing and internal components, which not only increases the difficulty of disassembly and assembly but also easily damages the casing or internal components during the process. Furthermore, inadequate heat dissipation is a common issue in existing single-screen digital extender technology with dual network cable extensions. These devices typically need to operate under prolonged, high-load conditions to support stable data transmission and clear screen display. However, due to design limitations, many existing digital extenders have significant shortcomings in heat dissipation.

[0004] Specifically, traditional digital extenders often employ simple ventilation holes to dissipate heat through natural convection. While this method can alleviate overheating to some extent, its effectiveness is often unsatisfactory under high loads or in high ambient temperatures. Heat buildup inside the device not only degrades performance but can also pose a range of safety hazards. Therefore, we propose a single-screen digital extender with dual network cable extension capabilities. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-5 A single-screen digital extender with dual network cable extension includes an outer shell 1 and a base shell 2 that are fitted together vertically. The single-screen digital extender also includes multiple data transmission interfaces, heat dissipation holes 3, an air inlet, a cooling fan 4, and a baffle plate 5.

[0032] The heat dissipation hole 3 is opened on the first side wall where the outer shell 1 and the bottom shell 2 are attached to each other, and the air inlet is opened on the second side wall where the outer shell 1 and the bottom shell 2 are attached to each other. The first side wall and the second side wall are arranged opposite to each other.

[0033] The cooling fan 4 and multiple guide plates 5 are both mounted on the base plate housing 2. The cooling fan 4 is positioned near the air inlet on one side of the base plate housing 2, and two guide plates 5 are correspondingly mounted at each air outlet of the cooling fan 4.

[0034] Multiple data transmission interfaces are located on the third side wall of the housing 1 of the single-screen digital extender.

[0035] In this embodiment of the invention, a highly efficient heat dissipation system is formed by setting heat dissipation holes, air inlets, cooling fans, and guide plates. On the one hand, in this heat dissipation system, the cooling fans blow air into the equipment, which works in conjunction with the heat dissipation holes to achieve heat dissipation. On the other hand, the design of the guide plates causes the air blown out of each air outlet of the cooling fans to be blown out along the gradually narrowing ventilation channels, realizing the Venturi effect, increasing the airflow speed, and improving the heat dissipation efficiency.

[0036] The above dual-network cable extension single-screen digital extender can be used for the transmitter (TX) and / or the receiver (TX).

[0037] Multiple data transmission interfaces include an ETH1 OUT network cable interface, an ETH2 OUT network cable interface, a USB IN interface, and an HDMI IN interface on the transmitter; the data transmission interface structure on the RX receiver includes an ETH1 IN network cable interface, an ETH2 IN network cable interface, a USB HID interface, and an HDMI OUT interface.

[0038] The base plate housing 2 is U-shaped with openings on both sides. The bottom ends of the outer shell 1 and the base plate housing 2 are flush. The bottom ends of the outer shell 1 are fixed with integrated side ear plates. The side ear plates are provided with through-type positioning holes near both ends. These designs enhance the stability of the equipment and facilitate its installation.

[0039] The dual-network cable extended single-screen digital extender also includes multiple sets of heat dissipation fins 6. The multiple sets of heat dissipation fins 6 are fixedly installed on the top inner wall of the outer casing 1, and the bottom ends of the multiple sets of heat dissipation fins 6 are attached to the electronic components in the base plate casing 2. The multiple sets of heat dissipation fins 6 are distributed along the air outlet direction of the multiple sets of guide plates 5 on the cooling fan 4 to improve heat conduction efficiency.

[0040] The heat dissipation fins 6 are in a continuous S-shaped bend, and multiple sets of heat dissipation fins 6 are arranged in three staggered rows along the air outlet direction of multiple sets of air guide plates 5. The length and width of each row of heat dissipation fins 6 increase sequentially along the air outlet direction of multiple sets of air guide plates 5. The bend-shaped multiple sets of heat dissipation fins 6 distributed along the air outlet direction can divert airflow, and the gaps formed can accelerate airflow. At the same time, the bend-shaped heat dissipation fins 6 increase the contact area between the heat dissipation fins 6 and the airflow, further improving the heat dissipation efficiency.

[0041] In addition, the design of the heat dissipation fins and air deflectors not only improves heat dissipation efficiency, but also allows for reasonable distribution and acceleration of airflow inside the device, further enhancing the device's performance.

[0042] A sleeve structure is provided between the outer shell 1 and the base shell 2. The sleeve structure includes positioning slots 7 and positioning posts 8. Two sets of vertical positioning slots 7 are opened on the outer side walls of the vertical sections on both sides of the base shell 2, and the tops of the positioning slots 7 on both sides of the base shell 2 are open. The positioning posts 8 are fixedly installed on the inner walls of both sides of the outer shell 1 to engage with the positioning slots 7. The distance between the two sets of positioning slots 7 on the same side of the base shell 2 and the openings on both sides of the base shell 2 is different. The sleeve structure, including the positioning slots and positioning posts, ensures the accuracy and stability of the outer shell and the base shell when sleeved. The outer shell 1 and the base shell 2 can be stably sleeved together by the above sleeve structure, while also facilitating disassembly and assembly.

[0043] A fixing structure is provided between the outer shell 1 and the base shell 2. The fixing structure includes a horizontal shaft 10, a torsion spring 11, a fixed top plate 12, a fixing groove 13, and a curved plate 14. A rectangular vertical groove 9 is formed on the inner wall of the outer shell 1 corresponding to the vertical end of the base shell 2. The horizontal shaft 10 is fixedly installed in the rectangular vertical groove 9 near the bottom end. A fixing groove 13 is formed on the vertical end of the base shell 2 corresponding to the position of the rectangular vertical groove 9. A fixing groove 13 is sleeved on the horizontal shaft 10. The top plate 12 is inclined and its top end fits against the inner top wall of the mounting groove 13. A torsion spring 11 is fixedly sleeved on the horizontal shaft 10 at the position corresponding to the top plate 12, and both ends of the torsion spring 11 are fixedly connected to the horizontal shaft 10 and the top plate 12, respectively. An integrated curved plate 14 is fixedly provided on the outer side wall of the top plate 12, and one end of the curved plate 14 slides out of the outer side wall of the outer shell 1. By pinching the curved plate and pulling the top plate, the outer shell and the bottom shell can be easily separated, facilitating internal inspection and maintenance. After maintenance, the top plate can automatically reset due to the deformation force of the torsion spring, realizing the rapid fixation of the outer shell and the bottom shell.

[0044] The inner top walls of the rectangular vertical groove 9 and the fixed slot 13 are both curved, and the top of the fixed shell top plate 12 is semi-circular curved. The inner top walls of the rectangular vertical groove 9 and the curved plate 14, as well as the center of the curved circle formed by the curved plate 14, are on the same horizontal line as the axis of the horizontal shaft 10. Therefore, when the fixed shell top plate 12 is pulled along the curved direction of the curved plate 14, the fixed shell top plate 12 will flip into the rectangular vertical groove 9 with the horizontal shaft 10 as the axis.

[0045] Working principle: When the dual-network cable extended single-screen digital extender is working, the cooling fan 4 blows air into the interior of the dual-network cable extended single-screen digital extender and the side heat dissipation holes 3 are used for heat dissipation. The air blown out by each air outlet of the cooling fan 4 will be blown out along the gradually narrowing ventilation channel formed by the two guide plates 5 to achieve the Venturi effect, increase the airflow speed, and along the airflow direction, the airflow can contact multiple sets of heat dissipation fins 6. The multiple sets of heat dissipation fins 6 can further dissipate heat, and the multiple sets of bent heat dissipation fins 6 distributed in the airflow direction can divert the airflow, and the space formed can accelerate the airflow. At the same time, the bent heat dissipation fins 6 increase the contact area between the heat dissipation fins 6 and the airflow, further improving the heat dissipation efficiency.

[0046] When disassembling and repairing this single-screen digital extender, simply pinch the protruding end of the curved plate 14 from the side of the outer shell 1 and pull the top plate 12 along the curvature of the curved plate 14. Since the inner wall of the top of the rectangular vertical groove 9, the curved plate 14, and the center of the curvature formed by the curved plate 14 are on the same horizontal line as the axis of the horizontal shaft 10, the top plate 12 will flip around the horizontal shaft 10 and into the rectangular vertical groove 9. At this time, the top plate 12 will disengage from the fixed slot 13 and its top end will no longer be against the fixed slot. On the top inner wall of 13, the outer shell 1 and the bottom shell 2 can then be separated for internal inspection of the single-screen digital extender. When the inspection is completed and the device is installed, repeat the above process to flip the top plate 12 into the rectangular vertical groove 9, so that the outer shell 1 and the bottom shell 2 can be fitted together. When released, the deformation force of the torsion spring 11 can reset the top plate 12, that is, the top of the top plate 12 fits against the top inner wall of the slot 13, thus completing the fitting and fixing of the outer shell 1 and the bottom shell 2.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
