Description

Technical Field

[0001] This application relates to the field of cable protection and movable connections of equipment, and in particular to a concealed cable protection device for a movable keyboard. Background Technology

[0002] Computer peripherals play a vital role in modern life, especially keyboards, which are indispensable input devices for computers. Their user experience and the rationality of peripheral accessories have garnered widespread attention. With the rapid development of computer technology, people's needs for keyboards have become increasingly diverse, focusing not only on functionality but also on appearance and cable management. Good keyboard cable management not only improves the tidiness and aesthetics of the desktop but also avoids a series of potential problems caused by messy cables, thereby improving work and life efficiency and comfort to a certain extent.

[0003] In the past, the traditional way to manage keyboard cables was to leave them exposed on the desktop. This method was simple and straightforward, but it resulted in a cluttered desktop, severely impacting the overall aesthetics. In recent years, various solutions have been introduced to address cable management issues, commonly including cable clips and cable management trays. Cable clips can bundle multiple cables together, reducing their spread; cable management trays provide a relatively organized space to neatly store cables. However, these solutions are primarily designed for fixed cabling needs.

[0004] The traditional method of directly exposing keyboard cables not only affects aesthetics but also makes them highly susceptible to damage from external factors. While existing solutions such as cable clips and cable management channels have improved the messy cable situation to some extent, they are not suitable for scenarios where the keyboard is frequently moved and cannot provide comprehensive and effective protection for the keyboard cables, leaving the cables still directly exposed and prone to damage. Utility Model Content

[0005] The purpose of this application is to provide a concealed wiring protection device for a movable keyboard.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: a concealed wiring protection device for a movable keyboard, comprising:

[0007] Mounting bracket, wherein the mounting bracket is provided with slide rails;

[0008] A slider is slidably disposed on the slide rail and is capable of moving along the slide rail toward or away from the mounting bracket.

[0009] A keyboard tray, mounted on the slider, is used to securely mount the keyboard.

[0010] The cable management frame includes several cable management frames that are hinged together in sequence. One end of each cable management frame is rotatably connected to the mounting frame, and the other end is rotatably connected to the keyboard tray. The cable management frame can be folded or extended as the slider moves, and the cable management frame has a cable management channel for guiding and completely wrapping the keyboard cable.

[0011] By adopting the above technical solution, the keyboard can move freely along the slide rail driven by the slider. At the same time, the cable tray folds or extends as the slider moves. Its internal cable routing channel can completely wrap and guide the keyboard cable, avoiding the mess and damage caused by exposed cables. This solves the management problem caused by the movement of traditional keyboard cables. The retractable cable tray design allows users to adjust the keyboard distance according to their needs, improving the flexibility of use. When not in use, the cable tray can be retracted and hidden, effectively reducing the space occupied by the device. It combines aesthetics and practicality, meets the cable management needs of scenarios with frequent keyboard movement, and is more adaptable to dynamic usage environments, fully protecting the keyboard cable and optimizing the use of desktop space.

[0012] Optionally, the mounting bracket has a first hidden slot and the keyboard tray has a second hidden slot. When the slider moves to a position close to the mounting bracket, the cable tray can retract and embed itself into the first hidden slot and the second hidden slot.

[0013] By adopting the above technical solution, the first hidden slot on the mounting bracket and the second hidden slot on the keyboard tray form a linked storage structure. When the slider moves the keyboard tray close to the mounting bracket, the cable management bracket can be precisely retracted and embedded in the double hidden slots, making the entire cable management device completely hidden, further reducing space occupation and improving desktop tidiness. The design of the double hidden slots ensures that the cable management bracket is stably limited in the stored state, preventing shaking or accidental pop-out. At the same time, the protective function of the hidden slots can prevent the cable management bracket from accumulating dust or being impacted by external forces when not in use, extending the service life of the device. Moreover, after storage, the position of the keyboard tray and the mounting bracket fits more compactly, and the overall appearance is simpler and more beautiful, meeting the user's dual needs for efficient use of desktop space and aesthetic appeal of the device.

[0014] Optionally, the cable tray includes a first cable tray and a second cable tray; the end of the first cable tray is provided with a mounting boss, and the end of the second cable tray is provided with a mounting through hole, wherein the mounting boss is rotatably embedded in the mounting through hole.

[0015] By adopting the above technical solution, the cable management frame is divided into a first cable management frame and a second cable management frame. Through the rotatable embedding structure of the mounting boss and mounting through hole, the cable management frame has flexible folding and extension performance. It can accurately follow the movement of the slider and move synchronously, avoiding cable pulling or tangling problems caused by keyboard position adjustment. The hinge design allows the two cable management frames to rotate relative to each other within a certain angle range, which not only ensures the structural stability of the cable management frame in the unfolded state, but also forms a compact storage form when folded. At the same time, the cooperation structure of the mounting boss and mounting through hole can effectively limit the axis of rotation, making the extension and retraction of the cable management frame more controllable, ensuring that the cable channel remains continuous during movement, thereby achieving full protection of the keyboard cable and significantly improving the device's ability to adapt to the dynamic movement of the keyboard.

[0016] Optionally, the outer peripheral wall of the mounting boss is provided with a limiting groove along the circumferential direction, and the inner wall of the mounting through hole is provided with a corresponding limiting strip. The limiting strip is fitted into the limiting groove to restrict the first cable routing frame and the second cable routing frame from separating axially.

[0017] By adopting the above technical solution, the limiting groove on the outer peripheral wall of the mounting boss and the limiting strip on the inner wall of the mounting through hole form a fitting structure, which can effectively limit the axial separation of the first and second cable routing frames, ensuring that the cable routing frame remains structurally stable during frequent folding and extension, and avoiding cable channel misalignment or cable exposure caused by axial movement. This limiting design provides reliable anti-detachment protection while allowing the two cable routing frames to rotate relative to each other, making the extension and retraction of the cable routing frame more stable and controllable. Even in usage scenarios where the keyboard moves frequently, it can maintain the continuity and sealing of the cable routing channel, improve the durability and reliability of the device, and provide a more solid structural support for the full protection of the keyboard cable.

[0018] Optionally, the first cable routing frame includes a first base and a first cover plate. The first base has a cable inlet near the end of the mounting bracket, and a first cable groove is formed in the recess of the first base. When the first cover plate is fastened to the first base, it forms a first closed channel segment with the first cable groove. The second cable routing frame includes a second base and a second cover plate. The second base has a cable outlet near the end of the keyboard tray, and a second cable groove is formed in the recess of the second base. When the second cover plate is fastened to the second base, it forms a second closed channel segment with the second cable groove.

[0019] By adopting the above technical solution, the first base of the first cable routing frame and the first cover plate are fastened together to form a first closed channel section, and the second base of the second cable routing frame and the second cover plate are fastened together to form a second closed channel section. This split-type closed structure can completely wrap the keyboard cable in the cable routing channel, effectively preventing the cable from contacting the outside world and causing wear, pulling, or tangling, thus achieving full protection for the keyboard cable. The setting of the inlet and outlet ports allows the keyboard cable to be passed in and out in an orderly manner. Combined with the concave cable groove design, it ensures the stability of the cable position in the cable routing channel and avoids problems such as poor contact caused by shaking. At the same time, the detachable cover plate structure facilitates the user's cable threading or maintenance, improves the ease of use of the device, and significantly enhances the protection effect and convenience of use for the keyboard cable.

[0020] Optionally, the mounting boss is hollow to form an axially continuous transition channel, which is coaxially connected with the mounting through hole; the first closed channel segment, the mounting through hole, the transition channel, and the second closed channel segment are sequentially connected to form a continuous and closed wiring channel; after the keyboard cable enters from the inlet, it passes through the first closed channel segment, the mounting through hole, the transition channel, and the second closed channel segment in sequence, and finally exits from the outlet.

[0021] By adopting the above technical solution, the axially continuous transition channel formed by the hollow mounting boss is coaxially connected with the mounting through hole, so that the first closed channel section, the mounting through hole, the transition channel, and the second closed channel section are sequentially connected to form a continuous and closed cable routing channel. After the keyboard cable enters from the inlet, it can pass through this channel without being exposed and exit from the outlet. This not only solves the problem of easy exposure and bending of cables at the hinge, but also ensures that the cables move smoothly in the transition channel and the mounting through hole when the cable tray is folded or extended, avoiding cable squeezing or jamming caused by changes in angle. The continuous and closed cable routing channel completely wraps the keyboard cable, effectively preventing dust accumulation, external wear and tear, and cable tangling. Compared with the defects of easy damage to cables at the hinge in the existing technology, this significantly improves the integrity of cable protection and the reliability of the device. At the same time, the neat cable routing path also makes the desktop layout more tidy, meeting the user's needs for efficient management and protection of keyboard cables.

[0022] Optionally, the first base is provided with a first rotation limit block, and the second base is provided with a second limit block.

[0023] By adopting the above technical solution, the first rotation limit block on the first base and the second limit block on the second base form a rotation angle limiting structure, which can accurately limit the unfolding and folding angles of the first and second cable routing frames. This avoids damage to cables due to excessive bending caused by excessive rotation of the cable routing frame, or affects the keyboard's movement range due to insufficient rotation angle. This limiting design ensures that the cable routing frame maintains a reasonable rotation range during extension and retraction, ensuring that the keyboard can be adjusted according to needs, and preventing the cable routing channel from being misaligned or broken due to abnormal angles. This improves the stability of the device during dynamic use. At the same time, the setting of the limit block can also reduce the shaking when the cable routing frame rotates, making the keyboard move more smoothly. This effectively solves the problem of cable protection failure caused by the unrestricted rotation angle of existing cable routing frames, providing more reliable motion protection for keyboard cables.

[0024] Optionally, the mounting bracket is equipped with anti-collision pads.

[0025] By adopting the above technical solution, the anti-collision pads on the mounting bracket can buffer and protect the keyboard tray when the slider moves the keyboard tray to its extreme position near the mounting bracket. This effectively reduces the impact force generated by the collision between the two, avoiding damage to the mounting bracket or keyboard tray structure caused by rigid collisions. At the same time, it reduces collision noise and improves the user experience. The elastic material of the anti-collision pads can also play a shock-absorbing role during frequent movement of the keyboard tray, preventing keyboard displacement or cable tray loosening due to vibration, and enhancing the overall structural stability and durability of the device. In addition, the anti-collision pads further optimize the fit of the device when stored, making the keyboard tray fit the mounting bracket more tightly and the appearance cleaner, meeting the user's needs for device safety and user comfort.

[0026] In summary, this application has at least the following beneficial effect:

[0027] 1. The keyboard can move freely along the rails with the slider, and the cable management rack folds or extends with the slider. Its internal cable management channels can completely wrap and guide the keyboard cables, avoiding the mess and damage caused by exposed cables. This solves the management problems caused by the movement of traditional keyboard cables. The retractable cable management rack design allows users to adjust the keyboard distance according to their needs, improving the flexibility of use. When not in use, the cable management rack can be retracted and hidden, effectively reducing the space occupied by the device. It combines aesthetics and practicality, meets the cable management needs of scenarios with frequent keyboard movement, and can adapt to dynamic usage environments, fully protecting the keyboard cables and optimizing desktop space utilization.

[0028] 2. The first hidden slot on the mounting bracket and the second hidden slot on the keyboard tray form a linked storage structure. When the slider moves the keyboard tray close to the mounting bracket, the cable management bracket can precisely retract and embed into the double hidden slots, completely concealing the entire cable management device, further reducing space occupation and improving desktop tidiness. The double hidden slot design ensures that the cable management bracket is stably limited in the stored state, preventing shaking or accidental pop-out. At the same time, the protective function of the hidden slots can prevent the cable management bracket from accumulating dust or being subjected to external impacts when not in use, extending the service life of the device. Moreover, after storage, the position of the keyboard tray and the mounting bracket fits more compactly, and the overall appearance is simpler and more beautiful, meeting the user's dual needs for efficient use of desktop space and aesthetic appeal of the device.

[0029] 3. The axially continuous transition channel formed by the hollow mounting boss is coaxially connected with the mounting through hole, allowing the first closed channel segment, the mounting through hole, the transition channel, and the second closed channel segment to sequentially connect to form a continuous and closed cable routing channel. After the keyboard cable enters from the inlet, it can pass through this channel without any exposure and exit from the outlet. This not only solves the problem of cables being easily exposed and bent at the hinge, but also ensures that the cables move smoothly within the transition channel and the mounting through hole when the cable tray is folded or extended, avoiding cable compression or jamming caused by changes in angle. The continuous and closed cable routing channel completely wraps the keyboard cable, effectively preventing dust accumulation, external wear, and cable tangling. Compared with the shortcomings of existing technologies where cables are easily damaged at the hinge, this significantly improves the integrity of cable protection and the reliability of the device. At the same time, the neat cable routing path also makes the desktop layout more tidy, meeting the user's needs for efficient management and protection of keyboard cables.

[0037] The present application will be further described in detail below with reference to the accompanying drawings.

[0038] In this embodiment, refer to Figures 1-5 A concealed cable management protection device for a movable keyboard includes a mounting bracket 1, a slide rail 2, a slider 3, a keyboard tray 4, and a cable management bracket 5. The slider 3 is slidably mounted on the slide rail 2 of the mounting bracket 1, allowing it to move towards or away from the mounting bracket 1 along the slide rail 2. The keyboard tray 4 is mounted on the slider 3. One end of the cable management bracket 5 is rotatably connected to the mounting bracket 1, and the other end is rotatably connected to the keyboard tray 4, allowing the cable management bracket 5 to fold or extend as the slider 3 moves. Furthermore, the cable management bracket 5 has cable management channels for guiding and completely enclosing the keyboard cables, achieving the effect of allowing the keyboard to move freely while protecting the keyboard cables, preventing them from being exposed, cluttered, or damaged. The sliding of the slider 3 on the slide rail 2 causes the keyboard tray 4 to move, which in turn causes the connected cable management bracket 5 to fold or extend, while the cable management channels effectively enclose the keyboard cables.

[0039] Specifically, the mounting bracket 1 is 505.12mm long and has a slide rail 2. The mounting bracket 1 is typically made of metal or high-strength plastic, providing good stability and support. The slide rail 2 can be a common dovetail rail or a ball bearing rail. The dovetail rail has a simple structure, is easy to install, and is less expensive; the ball bearing rail offers better smoothness of sliding. The slide rail 2 is fixed to the mounting bracket 1 by bolts or welding to ensure its stability.

[0040] The slider 3 is slidably mounted on the slide rail 2. The slider 3 is generally made of wear-resistant engineering plastic with a smooth surface to reduce friction with the slide rail 2. Its interior can be designed with grooves that fit the slide rail 2, ensuring accurate sliding along it. For example, if it is a dovetail slide rail, the slider 3 will have a corresponding dovetail-shaped groove; if it is a ball bearing slide rail 2, the slider 3 will cooperate with the ball bearings to achieve smooth movement.

[0041] The keyboard tray 4 is mounted on the slider 3. The keyboard tray 4 is 505.03mm long and 131.82mm wide. It can be a flat plate made of wood, plastic, or metal. Its surface can be treated with an anti-slip coating, such as adding small bumps or a non-slip surface, to prevent the keyboard from sliding. The keyboard tray 4 is fixedly connected to the slider 3 by bolts or clips, ensuring that the keyboard tray 4 moves synchronously when the slider 3 moves.

[0042] The cable tray 5 includes several cable trays that are hinged together in sequence. Here, we take a first cable tray 51 and a second cable tray 52 as an example. The end of the first cable tray 51 is provided with a mounting boss 53. The mounting boss 53 can be a cylindrical structure, made of metal or hard plastic, with a relatively smooth surface. The end of the second cable tray 52 is provided with a mounting through hole 8. The diameter of the mounting through hole 8 is adapted to the mounting boss 53, and it is also made of metal or hard plastic. The mounting boss 53 is rotatably embedded in the mounting through hole 8, thus achieving the hinge connection between the first cable tray 51 and the second cable tray 52. ​​To prevent the first cable tray 51 and the second cable tray 52 from separating axially, a limiting groove 9 is formed circumferentially on the outer peripheral wall of the mounting boss 53. The shape of the limiting groove 9 can be rectangular or semi-circular. A limiting strip 10 is correspondingly provided on the inner wall of the mounting through hole 8. The limiting strip 10 can be a rubber strip or a plastic strip, with a certain degree of elasticity, and can fit well into the limiting groove 9.

[0043] The first cable management bracket 51 includes a first base 511 and a first cover plate 512. The first base 511 has a cable inlet 11 near the mounting bracket 1. The cable inlet 11 can be circular or square to facilitate the insertion of the keyboard cable. A first cable groove 12 is recessed within the first base 511. The shape of the first cable groove 12 is adapted to the shape of the keyboard cable and is generally elongated. When the first cover plate 512 is fastened to the first base 511, it forms a first closed channel section with the first cable groove 12. The first cover plate 512 can be connected to the first base 511 by snap-fit ​​or magnetic attraction, facilitating installation and removal, and enabling convenient maintenance of the keyboard cable.

[0044] The second cable management bracket 52 includes a second base 521 and a second cover plate 522. The second base 521 has a cable outlet 13 near the keyboard tray 4, the shape and size of which are similar to the cable inlet 11. A second cable groove 14 is recessed within the second base 521. When the second cover plate 522 is fastened to the second base 521, it forms a second closed channel section with the second cable groove 14. Similarly, the second cover plate 522 is connected to the second base 521 via a snap-fit ​​or magnetic attraction.

[0045] The hollow mounting boss 53 forms an axially continuous transition channel 15, which is coaxially connected to the mounting through hole 8. The first closed channel section, the mounting through hole 8, the transition channel 15, and the second closed channel section are sequentially connected to form a continuous and closed wiring channel. After the keyboard cable enters from the inlet 11, it passes through the first closed channel section, the mounting through hole 8, the transition channel 15, and the second closed channel section in sequence, finally exiting from the outlet 13. This design ensures that the keyboard cable is completely enclosed within the wiring channel, providing excellent protection.

[0046] Reference Figures 1-2 The mounting bracket 1 has a first hidden slot 6, and the keyboard tray 4 has a second hidden slot 7. When the slider 3 moves close to the mounting bracket 1, the cable management bracket 5 can retract and fit into the first hidden slot 6 and the second hidden slot 7. The size and shape of the first hidden slot 6 and the second hidden slot 7 are adapted to the retracted cable management bracket 5. The hidden slots ensure that the cable management bracket 5 does not take up too much space when not in use, making the desktop tidier.

[0047] Reference Figures 4-5 The first base 511 is provided with a first rotation limit block 16, and the second base 521 is provided with a second limit block 17. The first rotation limit block 16 and the second limit block 17 can be block-shaped protrusions made of rubber or plastic. Their function is to limit the rotation angle between the first cable routing frame 51 and the second cable routing frame 52, so as to avoid excessive rotation and structural damage.

[0048] Reference Figure 1 The mounting bracket 1 is equipped with anti-collision pads 18, which can be made of sponge or silicone and have good cushioning performance. The anti-collision pads 18 are attached to the mounting bracket 1 with adhesive. When the slider 3 approaches the mounting bracket 1, the anti-collision pads 18 can act as a buffer, reducing the noise generated by the collision and the damage to the device.

[0049] The implementation principle of this embodiment is as follows: The device has an ingenious overall structural design. The keyboard can move freely by sliding the slider 3 on the slide rail 2. The foldable and extendable cable tray 5 not only accommodates the keyboard's movement but also hides the keyboard cables within the internal cable routing channels, avoiding the mess and damage caused by exposed cables. Simultaneously, the hidden slot design further optimizes space utilization, reducing the space occupied by the device when not in use. Compared to traditional keyboard cable management methods, this method has significant advantages, satisfying the needs of scenarios with frequent keyboard movement while protecting the keyboard cables and improving the neatness and aesthetics of the desktop.

[0050] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
