An apparatus comprising a KVM switching assembly

Abstract

The application discloses a device comprising a KVM switching combination structure, and particularly relates to the field of KVM switching, which comprises a fixed support plate and two groups of positioning components arranged on the surface of the fixed support plate. The positioning component comprises a setting sliding track, which is arranged on the surface of the fixed support plate. A plurality of groups of curved sliding blocks are slidably connected to the inner wall of the setting sliding track. A linkage block is fixedly connected to the two sides of each group of the curved sliding blocks. An auxiliary plug rod is inserted into one side of the linkage block. The extrusion inside the KVM switching combination frame is always kept in a clamped fixed state through the meshing of the torsional spring telescopic rod and the curved sliding block. When the torsional spring telescopic rod moves to the deepest part of the setting sliding track and the curved sliding block is meshed, the spring part on the surface of the torsional spring telescopic rod, which does not receive external pressure, restores to the original state and is meshed with the auxiliary thread. Thus, the computer is prevented from being affected by external vibration, and the connecting line between the KVM switching combination structure is always kept horizontally connected.

Description

Technical Field

[0001] This invention relates to the field of KVM switching technology, and more specifically, to a device including a KVM switching assembly structure. Background Technology

[0002] KVM enables access to and control of a computer by directly connecting to keyboard, video, and mouse ports. KVM technology requires no software modification on the target server, meaning that the target computer can be accessed at any time within the BIOS environment. KVM provides true motherboard-level access and supports multi-platform servers and serial devices.

[0003] However, most current KVM switching assembly structures are used in the military, and they are often installed in military command posts or large aircraft carriers. In this case, the equipment is more susceptible to vibration due to external artillery bombardment. Since there are gaps between the KVM switching assembly structures, the whole structure is more susceptible to the effects of external vibration, which may cause the connection lines between the KVM switching assembly structures to break. Therefore, we propose a device that includes a KVM switching assembly structure. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a device including a KVM switching assembly structure. The device is kept in a locked and fixed state by the internal compression of the KVM switching assembly frame through the engagement of a torsion spring telescopic rod and a curved slider. Ultimately, as the torsion spring telescopic rod moves to the deepest point of the mounting slide rail and engages with the curved slider, the spring portion on the surface of the torsion spring telescopic rod that has not received external pressure returns to its original shape and engages with the auxiliary thread. This achieves the goal of preventing the computer from being easily affected by external vibrations, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a device including a KVM switching assembly structure, comprising a fixed support plate and two sets of positioning components on the surface of the fixed support plate. Each positioning component includes a mounting slide rail, which is located on the surface of the fixed support plate. Multiple sets of curved sliders are slidably connected to the inner wall of the mounting slide rail. Linkage blocks are fixedly connected to both sides of the multiple sets of curved sliders. An auxiliary rod is inserted into one side of each linkage block. The auxiliary rod is fixedly installed on the inner wall of the mounting slide rail. A corresponding number of positioning threads are provided on the side of the curved slider away from the mounting slide rail. An auxiliary thread is provided on the surface of the mounting slide rail. A receiving groove is provided at the connection between the mounting slide rail and the curved slider. The multiple sets of curved sliders are irregularly installed, and each set of positioning threads is connected.

[0006] A support base plate is fixedly connected to one side of the fixed support plate, and a KVM switching assembly frame is fixedly connected to one side of the support base plate.

[0007] The beneficial effects of adopting the above-mentioned further scheme are as follows: When the second roller rotates clockwise with the torsion spring telescopic rod, the torsion spring telescopic rod moves into the interior of the placement slide rail along the running trajectory of the placement slide rail. Then, multiple sets of curved sliders fall in a stepped shape, layer by layer. However, the threads on the surface of the linkage block are always connected to the threads on the surface of the linkage block of the next layer. When the torsion spring telescopic rod rotates along the positioning thread and moves into the interior of the placement slide rail, since the torsion spring has elasticity and the curved slider can move towards the receiving groove along the auxiliary insert rod through the linkage block under external force, the torsion spring telescopic rod always meshes with the curved slider and rotates, while simultaneously moving into the interior of the placement slide rail.

[0008] In a preferred embodiment, a combined slide plate frame is slidably connected to one side of the KVM switching assembly frame, a side slide rail frame is provided at the connection between the combined slide plate frame and the KVM switching assembly frame, a speaker frame is fixedly connected to the bottom end of the combined slide plate frame, a positioning slide frame is fixedly connected to the bottom end of the speaker frame, a fixed slide rail frame is slidably connected to the outer surface of the positioning slide frame, a positioning slide rod is slidably connected to the inner side of the positioning slide frame, and the positioning slide rod is fixedly connected to one side of the fixed slide rail frame.

[0009] The beneficial effect of adopting the above-mentioned further solution is that: when the conveyor belt rotates around the outer surfaces of the first and second rollers, the second and fourth positioning rollers move along the track of the support base plate towards one side of the fixed slide rail frame. It should be noted that the guide track of the support base plate is a curved channel designed to conform to the movement trajectory of the second and fourth positioning rollers.

[0010] In a preferred embodiment, a first rotating rod is rotatably connected inside the positioning sliding frame, a first locking wheel is rotatably connected to the outer surface of the first rotating rod, a rotating belt is wound around the outer surface of the first locking wheel, a first hinge rod is hinged to one side of the first rotating rod, and a fourth hinge rod is hinged to the other side of the first rotating rod.

[0011] The beneficial effects of adopting the above-mentioned further solution are: the second rotating roller drives the first positioning rotating wheel to rotate through the rotating belt, and then adjusts the position of the combined skateboard frame through the first positioning rotating wheel. At the same time, the position of the second rotating roller also limits the movement distance of the combined skateboard frame, making it convenient to adjust the position according to the position of the staff.

[0012] In a preferred embodiment, a second rotating rod is hinged to one side of the first hinge rod, a second locking wheel is rotatably connected to the outer surface of the second rotating rod, the rotating belt is wrapped around the outer surface of the second locking wheel, an auxiliary slider is slidably connected to one side of the fourth hinge rod, a second rotating roller is rotatably connected to the top of the auxiliary slider, a threaded rod is threadedly connected to the inside of the auxiliary slider, and a handle is fixedly connected to one end of the threaded rod that passes through the fourth hinge rod.

[0013] The beneficial effects of adopting the above-mentioned further solution are: the speaker rack serves as a speaker mounting mechanism, which facilitates the amplification of command transmission sound on the battlefield, and the auxiliary slider and the threaded rod are in an engaged connection state. When the operator manually rotates the handle, the handle adjusts the position of the auxiliary slider through the threaded rod and the auxiliary slider, and the second rotating roller adjusts its position accordingly.

[0014] In a preferred embodiment, a telescopic conduit is fixedly connected to one side of the second roller, and a power connection frame is electrically connected to one side of the telescopic conduit. The power connection frame is fixedly installed on the top of the KVM switching assembly frame.

[0015] The beneficial effects of adopting the above-mentioned further solution are: the limiting block can hold the output end wire head, such as the USB head in the prior art, and at the same time the guide rail of the limiting sleeve eventually extends to the output end position of the power connector bracket, ensuring the connection between the output end wire and the output end, so that the telescopic tube can only be stretched a fixed distance inside the power connector bracket.

[0016] In a preferred embodiment, a fourth rotating rod is hinged to one side of the fourth hinge rod, a fourth positioning wheel is rotatably connected to the outer surface of the fourth rotating rod, a third hinge rod is hinged to one side of the fourth rotating rod, a first rotating roller is rotatably connected to the top of the third hinge rod, a third rotating rod is hinged to one side of the third hinge rod, a third positioning wheel is rotatably connected to the outer side of the third rotating rod, a positioning frame is fixedly connected to the bottom end of the third positioning wheel, the positioning frame is fixedly installed on one side of the KVM switching assembly frame, and an audio speaker rack is fixedly connected to the inside of the KVM switching assembly frame through the positioning frame.

[0017] The beneficial effects of adopting the above-mentioned further solution are: the telescopic conduit is set as the output end line of the KVM combined structure, a part of the telescopic conduit is fixed on the surface of the second roller, and the telescopic conduit is inserted into the output end of the power connection frame. Then, a limit sleeve is provided at the connection between the telescopic conduit and the power connection frame. The limit sleeve is a guide rail with a limit block.

[0018] In a preferred embodiment, a second hinge rod is hinged to one side of the third rotating rod, and the second hinge rod is hinged to one side of the second rotating rod. The rotating belt is respectively wrapped around the outer surfaces of the fourth positioning rotating wheel, the third positioning rotating wheel, the second rotating roller, and the first rotating roller. The second positioning rotating wheel and the fourth positioning rotating wheel are slidably connected to one side of the supporting base plate. The top ends of the first rotating roller and the second rotating roller are fixedly connected to torsion spring telescopic rods, and the torsion spring telescopic rods are adapted to the positioning threads.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the compression inside the KVM switching assembly frame is always kept in a locked and fixed state through the engagement of the torsion spring telescopic rod and the curved slider. Finally, when the torsion spring telescopic rod moves to the deepest part of the mounting slide rail and is engaged with the curved slider, the spring part on the surface of the torsion spring telescopic rod that has not received external pressure returns to its original state.

[0020] The technical effects and advantages of this invention are as follows:

[0021] 1. The internal compression of the KVM switch unit is always kept in a locked and fixed state through the engagement of the torsion spring telescopic rod and the curved slider. When the torsion spring telescopic rod moves to the deepest part of the placement slide rail and engages with the curved slider, the spring part on the surface of the torsion spring telescopic rod that has not received external pressure returns to its original shape and engages with the auxiliary thread. This avoids the computer from being easily affected by external vibration, so that the connection lines between the KVM switch unit structures always remain horizontal.

[0022] 2. The guide rail of the limiting sleeve extends to the output end of the power connector bracket, ensuring the connection between the output wires. This prevents the telescopic cable from being stretched a fixed distance inside the power connector bracket. When the second roller slides clockwise along the fourth locking wheel, it carries the telescopic cable along the limiting sleeve to connect with the output end. This allows the computer mouse and keyboard to be powered on and used only when they are pushed out of the fixed slide rail bracket, preventing them from being hit by external objects when not in use, thus avoiding interference with computer operation.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Reference Figure 1-3Example 1: A combined slide plate frame 6 is slidably connected to one side of the KVM switching combination frame 4. A side slide rail frame 3 is provided at the connection between the combined slide plate frame 6 and the KVM switching combination frame 4. A speaker frame 7 is fixedly connected to the bottom of the combined slide plate frame 6. A positioning slide frame 5 is fixedly connected to the bottom of the speaker frame 7. A fixed slide rail frame 2 is slidably connected to the outer surface of the positioning slide frame 5. A positioning slide rod 28 is slidably connected to the inner side of the positioning slide frame 5. The positioning slide rod 28 is fixedly connected to one side of the fixed slide rail frame 2. A first rotating rod 9 is rotatably connected inside the positioning slide frame 5. A first locking wheel 8 is rotatably connected to the outer surface of the first rotating rod 9. A rotating belt 10 is wound around the outer surface of the first locking wheel 8. A first hinge rod 17 is hinged to one side of the first rotating rod 9. A fourth hinge rod 20 is hinged to the other side of the first rotating rod 9. A second rotating rod 13 is hinged to one side of the fourth hinge rod 20. A second locking wheel 11 is rotatably connected to the outer surface of the second rotating rod 13. A rotating belt 10 is wrapped around the outer surface of the second locking wheel 11. An auxiliary slider is slidably connected to one side of the fourth hinge rod 20. A second rotating roller 23 is rotatably connected to the top of the auxiliary slider. A threaded rod 26 is threadedly connected to the inside of the auxiliary slider. A handle 24 is fixedly connected to one end of the threaded rod 26 that passes through the fourth hinge rod 20.

[0033] It should be noted that the fixed support plate 1 is fixedly installed inside the KVM switching assembly frame 4, and the motor, as the drive, is electrically connected to the third rotating rod 15. The motor is a Lido YE4 motor. The motor drives the third positioning rotating wheel 14 to rotate clockwise through the third rotating rod 15, and the third positioning rotating wheel 14 rotates synchronously with the rotating belt 10. The third positioning rotating wheel 14 drives the second positioning rotating wheel 11 to rotate around the second rotating rod 13 through the rotating belt 10. At the same time, the fourth positioning rotating wheel 22 rotates around the fourth rotating rod 31 with the third positioning rotating wheel 14 through the rotating belt 10. Since the first rotating rod 9 can only slide inside the fixed slide rail frame 2 through the positioning slide frame 5, and since the rotating belt 10 rotates around the first rotating roller 21 and the second rotating roller 23... When the outer surface rotates, the second positioning wheel 11 and the fourth positioning wheel 22 move along the track of the support base plate 12 towards one side of the fixed slide rail frame 2. It is explained here that the guide track of the support base plate 12 is a curved channel, which is used to conform to the movement trajectory of the second positioning wheel 11 and the fourth positioning wheel 22. The first positioning wheel 8 carries the combined slide frame 6 through the positioning slide frame 5 and slides along the positioning slide rod 28 on the inner wall of the fixed slide rail frame 2. The combined slide frame 6 places the computer mouse and keyboard through the groove on its surface, which facilitates the joint use and storage of the KVM combination structure, that is, the computer hardware, such as the computer mouse and keyboard. The use of the conveyor belt can reduce the rolling friction between the mechanisms. Compared with the traditional transmission method using guide rails, most of the guide rail mechanisms are metal. During the transmission of the KVM combination structure, the guide rail mechanisms are damaged due to the collision between metals.

[0034] Meanwhile, the speaker rack 7 serves as a speaker mounting mechanism, facilitating the amplification of command transmission on the battlefield. The auxiliary slider and the threaded rod 26 are in an engaged connection. When the operator manually rotates the handle 24, the handle 24 adjusts the position of the auxiliary slider through the threaded rod 26 and the auxiliary slider. The second roller 23 then adjusts its position accordingly. The second roller 23 drives the first locking wheel 8 to rotate through the belt 10, thereby adjusting the position of the combined slide frame 6 through the first locking wheel 8. At the same time, the position of the second roller 23 also limits the movement distance of the combined slide frame 6, making it easy to adjust the position according to the operator's body position.

[0035] Reference Figure 2-5 Example 2: A telescopic conduit 25 is fixedly connected to one side of the second roller 23. A power connector 29 is electrically connected to one side of the telescopic conduit 25. The power connector 29 is fixedly installed at the top of the KVM switching assembly 4. A fourth rotating rod 31 is hinged to one side of the fourth hinge rod 20. A fourth positioning wheel 22 is rotatably connected to the outer surface of the fourth rotating rod 31. A third hinge rod 19 is hinged to one side of the fourth rotating rod 31. A first roller 21 is rotatably connected to the top of the third hinge rod 19. A third rotating rod 15 is hinged to one side of the third hinge rod 19. A third positioning wheel 14 is rotatably connected to the outer side of the third rotating rod 15. A positioning frame 16 is fixedly connected to the bottom of the third positioning wheel 14. The positioning frame 16 is fixedly installed on one side of the KVM switching assembly 4. A speaker rack 7 is fixedly connected to the inside of the KVM switching assembly 4 through the positioning frame 16.

[0036] It should be noted that the telescopic tube 25 is set as the output cable of the KVM combination structure. A part of the telescopic tube 25 is fixed to the surface of the second roller 23. The telescopic tube 25 is inserted into the output end of the power connector 29. A limiting sleeve is set at the connection between the telescopic tube 25 and the power connector 29. The limiting sleeve is a guide rail with a limiting block. First, the limiting block can lock the output cable end, such as the USB head in the prior art. At the same time, the guide rail of the limiting sleeve eventually extends to the output end of the power connector 29, ensuring the connection between the output cable and the output end. This causes the telescopic tube 25 to be stretched only a fixed distance inside the power connector 29. When the second roller 23 slides clockwise along the fourth locking roller 22, the second roller 23 carries the telescopic tube 25 and connects to the output end along the limiting sleeve. Thus, the computer mouse and keyboard can only be powered on and used when they are pushed out of the fixed slide rail 2. This prevents the computer mouse and keyboard from being hit by external objects when not in use, thus interfering with computer operation.

[0037] Reference Figure 4-7Example 3: A device including a KVM switching combination structure includes a fixed support plate 1 and two sets of positioning components 30 on the surface of the fixed support plate 1. The positioning components 30 include a mounting slide rail 3006, which is formed on the surface of the fixed support plate 1. Multiple sets of curved sliders 3001 are slidably connected to the inner wall of the mounting slide rail 3006. Linkage blocks 3002 are fixedly connected to both sides of the multiple sets of curved sliders 3001. An auxiliary rod 3005 is inserted into one side of the linkage block 3002. The auxiliary rod 3005 is fixedly installed on the inner wall of the mounting slide rail 3006. A corresponding number of positioning threads 3003 are formed on the side of the curved slider 3001 away from the mounting slide rail 3006. An auxiliary thread 3004 is formed on the surface of the mounting slide rail 3006. A storage groove is formed at the connection between the mounting slide rail 3006 and the curved slider 3001. The multiple sets of curved sliders 3001 are irregularly installed, and each set of positioning threads 3003 is connected.

[0038] A support base plate 12 is fixedly connected to one side of the fixed support plate 1. A KVM switching assembly frame 4 is fixedly connected to one side of the support base plate 12. A second hinge rod 18 is hinged to one side of the third rotating rod 15. The second hinge rod 18 is hinged to one side of the second rotating rod 13. The rotating belt 10 is respectively wrapped around the outer surfaces of the fourth positioning rotating wheel 22, the third positioning rotating wheel 14, the second rotating roller 23, and the first rotating roller 21. The second positioning rotating wheel 11 and the fourth positioning rotating wheel 22 are slidably connected to one side of the support base plate 12. A torsion spring telescopic rod 27 is fixedly connected to the top of the first rotating roller 21 and the second rotating roller 23. The torsion spring telescopic rod 27 is adapted to the positioning thread 3003.

[0039] It should be noted that when the second roller 23 rotates clockwise with the torsion spring telescopic rod 27, the torsion spring telescopic rod 27 moves into the mounting slide rail 3006 along its running trajectory. This causes the multiple sets of curved sliders 3001 to fall in a stepped shape, layer by layer. However, the threads on the surface of the linkage block 3002 are always connected to the threads on the surface of the linkage block 3002 of the next layer. When the torsion spring telescopic rod 27 rotates along the positioning thread 3003 and moves into the mounting slide rail 3006, due to the telescopic nature of the torsion spring and the ability of the curved slider 3001 to move along the auxiliary insert rod 3005 towards the receiving slot via the linkage block 3002 under external force, the torsion spring telescopic rod 27 remains engaged with and rotates with the curved slider 3001, while simultaneously moving into the mounting slide rail 3006. This ensures that when the combined slide frame 6 moves outward, the KVM switching combined frame 4... The internal compression is maintained in a locked and fixed state through the engagement of the torsion spring telescopic rod 27 and the curved slider 3001. Finally, when the torsion spring telescopic rod 27 moves to the deepest part of the placement slide rail 3006 and engages with the curved slider 3001, the spring part on the surface of the torsion spring telescopic rod 27 that has not received external pressure returns to its original state and engages with the auxiliary thread 3004. This achieves the goal of preventing the computer from being easily affected by external vibration, so that the connection lines between the KVM switching combination structures always remain horizontally connected.

[0040] To explain, when the motor drives the third rotating rod 15 to rotate counterclockwise, the third rotating rod 15 is equivalent to a lead screw mechanism connected to the motor, and the first locking wheel 8 is similarly stored deep in the fixed slide rail frame 2.

[0041] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships.
