Description

Technical Field

[0001] This utility model relates to the field of electric height-adjustable desks, and in particular to a concealed wiring device for electric height-adjustable desks. Background Technology

[0002] An electric height-adjustable desk is a modern office or home furniture piece that uses an electric drive system to flexibly adjust the desk height. It uses a motor as its core power source, combined with a mechanical transmission structure, to convert the motor's rotational motion into the linear lifting motion of the desk legs, thus allowing the desk to be freely adjusted within a certain range. It also features an intelligent control system, enabling precise height adjustment and the memorization of frequently used heights via buttons, touchscreen, or an app.

[0003] For example, a height-adjustable desk with easy wiring, disclosed in CN219680031U, includes a desk board, a lifting mechanism, a cable tray, a fixing block, fixing holes, and connecting parts. This utility model can hide and store the wires of office equipment while reducing the difficulty of installing the cable tray.

[0004] In practical use, the above solution suffers from several drawbacks. Because of the gap between the cable management hole and the cable tray box on the height-adjustable desk, the cables must be suspended between them. When the desk is raised or lowered, the cables are repeatedly stretched, leading to wear on the cable sheath and even breakage of the internal copper core over time. This severely impacts the stability of power supply and data transmission. Furthermore, the lack of a layered or organized structure within the cable tray box allows cables to pile up haphazardly, weakening the concealment effect and hindering heat dissipation due to cable compression, thus accelerating cable aging. Therefore, a concealed cable management device for electric height-adjustable desks needs to be designed.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] This utility model provides a hidden cable routing device for an electric lifting table to solve the problems of cables being easily damaged due to the gap between the cable routing hole and the cable tray box, disorderly stacking inside the box weakening the hiding effect and poor heat dissipation.

[0007] The present invention adopts the following technical solution: an electric height-adjustable desk with concealed cable routing device, mainly including a desk panel with cable routing holes; a lifting assembly disposed on the bottom surface of the desk panel, the lifting assembly being used to adjust the height of the desk panel, the lifting assembly including two sets of lifting rods; and a cable routing assembly disposed between the two sets of lifting rods, the cable routing assembly including a cable routing section disposed between the two sets of lifting rods, the cable routing section including a cable routing box two for providing a closed concealed space for the cable, and a concealing part connected to the bottom surface of the desk panel for concealing the cable suspended between the cable routing holes and the cable routing box two.

[0008] Furthermore, the wiring section also includes a right-angle bracket fixed to one side of the two sets of lifting rods that are close to each other. The second wiring box is fixed between the two sets of right-angle brackets. A cover plate is hinged to the second wiring box, and a wire is inserted through the cover plate at one end near the wiring hole.

[0009] Furthermore, the bottom surface of the second cable box is provided with through holes near both ends, which simultaneously provide heat dissipation for the cables.

[0010] Furthermore, the hidden part includes a cable box one fixed to the bottom surface of the tabletop. The cable box one is set perpendicular to the cable box two to form an L-shaped cable storage path. The upper surface of the cable box one has a cable inlet hole with rounded corners. The cable inlet hole is used to introduce the cable leading out of the cable box into the cable box one. The end of the cable box one near the cable box two has multiple sets of cable outlet holes, and the cable is suitable to enter the conductor through the cable outlet holes.

[0011] Furthermore, the bottom surface of the cable box has an opening, which serves as an operation window for manually threading cables.

[0012] Furthermore, multiple locking parts are connected between the second cable box and the cover plate. Each locking part includes a mounting base fixed to the side of the second cable box. A connecting shaft is laterally movably passed through the mounting base. Springs are connected to both ends of the connecting shaft. One end of each spring has a connector. One end of each of the two connectors is connected to a hanging rod. A hook portion adapted to the hanging rod is fixed to the side of the cover plate.

[0013] Furthermore, multiple sets of wire clips are arranged on the bottom surface of the inner wall of the second cable box. The wire clips are in the form of a ring structure with a notch and are made of plastic.

[0014] Furthermore, the conductor has a hollow, loop-shaped design and rounded edges. Through the loop-shaped hollow structure and rounded edges, the conductor is used to guide the cable into the cable box.

[0015] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects: An electric height-adjustable desk concealed cable management device, by setting up a concealed part, encloses and stores the suspended cables between the cable tray hole and the cable tray box, eliminating repeated pulling of the cables when the desk is raised and lowered, avoiding wear on the outer sheath and breakage of the copper core, and ensuring the stability of power supply and data transmission. The cable tray box provides a closed and concealed space for the cables, and with its orderly internal structure, it can prevent the cables from stacking disorderly, which not only enhances the concealment effect, but also reduces the heat dissipation obstruction caused by the cables squeezing each other, and delays cable aging. At the same time, when the lifting component adjusts the height of the desk, the cable tray component moves synchronously with the lifting rod to ensure that the cables are always in an orderly stored state, thus improving the overall safety, stability and service life of the device.

[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0019] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0020] Reference Figures 1-2 and Figure 4 As shown in the figure, an embodiment of the present invention provides an electric height-adjustable desk with a hidden cable routing device, including a tabletop 1, which provides a working surface for the user. The bottom surface of the tabletop 1 is fixed with a load-bearing frame 11, which enhances the load-bearing stability of the tabletop 1. A cable routing hole 12 is provided on the tabletop 1, which is a channel for cable routing. A lifting assembly 2 is provided on the bottom surface of the tabletop 1, which is used to adjust the height of the tabletop 1. The lifting assembly 2 includes two sets of table legs 21, and a vertically arranged support rod 24 is fixed on the table legs 21. The support rod 24 is hollow and one end is open. A load-bearing rod 211 is connected between the two sets of support rods 24. A drive unit is provided near both ends of the load-bearing rod 211, and a switch 13 for controlling the start and stop of the drive unit is fixed on the side of the tabletop 1. The two sets of drive components 22 are electrically connected to the switch 13 on the side of the table 1 via wires, and use pulse synchronization control technology to achieve coordinated operation. After the switch 13 sends a start signal, the two sets of drive components 22 receive the same pulse command to ensure that the output speed and direction are completely consistent. Each drive unit 22 has a bevel gear 23 fixed at its output end. A lead screw 25 is provided at the bottom bearing of the inner wall of the support rod 24. One end of the lead screw 25 is fixed with a bevel gear 26 that meshes with the bevel gear 23. A sliding seat 28 is threaded onto the lead screw 25. Vertical linear movement is achieved through the threaded engagement with the lead screw 25. A vertically arranged lifting rod 27 is fixed on the upper surface of the sliding seat 28. The lifting rod 27 is the connecting component between the sliding seat 28 and the load-bearing frame 11, transmitting the vertical movement of the sliding seat 28 to the tabletop 1. The lifting rod 27 is hollow and sleeved on the lead screw 25. Guide wheels 29 are movably arranged on both sides of the support rod 24 near the open position. The guide wheels 29 are the guiding components of the lifting rod 27, ensuring the stability of the vertical movement of the lifting rod 27 and preventing it from deviating during the lifting process. The load-bearing frame 11 is connected between the two sets of lifting rods 27. In practical use, when the height of the height-adjustable desk needs to be adjusted, the user sends a command via the switch 13 on the side of the desk 1. The two sets of drive components 22 start synchronously under pulse synchronization control, and their output drives the first bevel gear 23 to rotate. The first bevel gear 23 meshes with the second bevel gear 26, transmitting power to the lead screw 25, causing both lead screws 25 to rotate synchronously within the support rod 24. The lead screw 25 is threaded into the sliding seat 28. The sliding seat 28, limited by the inner wall of the support rod 24, can only move vertically, thereby driving the lifting rod 27 to smoothly rise and fall along the guide track of the guide wheel 29. The guide wheel 29 closely fits both sides of the lifting rod 27, effectively preventing swaying or deviation during lifting. The lifting rod 27, through the load-bearing frame 11 connected to the top, drives the desk 1 to achieve synchronous height adjustment, ensuring that the desk 1 always remains level.

[0021] like Figures 3-5 As shown, a cable management assembly 3 is connected between the two sets of lifting rods 27. This assembly 3 is used to neatly store cables inside the table, keeping the desktop tidy and preventing cable tangling. The assembly 3 includes a cable management section positioned between the two sets of lifting rods 27. This section includes a right-angle bracket 33 fixed to the adjacent sides of the two sets of lifting rods 27. A second cable management box 34 is connected and fixed between the two right-angle brackets 33. This box provides a closed, concealed space for the cables. A cover plate 35 is hinged to the second cable box 34. The cover plate 35 is a sealing component of the second cable box 34, which is convenient to open for inspection or organization of the internal cables. A wire member 36 is installed through the cover plate 35 near the end of the cable hole 12. The wire member 36 has a hollow U-shaped design and rounded edges. The U-shaped hollow structure and rounded edges prevent wear when the cable is threaded through. The wire member 36 is used to introduce the cable into the second cable box 34. Furthermore, through-holes 341 are provided on the bottom surface of the second cable box 34 near both ends. These through-holes 341, located away from the cable hole 12, are used to further guide the cable so that one end of the cable can be plugged into the socket for power supply. The through-holes 341 are also suitable for simultaneous heat dissipation of the cable. In addition, multiple sets of wire clips 37 are arranged on the bottom surface of the inner wall of the second cable box 34. The wire clips 37 have a ring structure with notches and are made of plastic to facilitate the neat arrangement of cables. The ring structure with notches can classify and fix multiple cables to prevent the cables from getting tangled inside the second cable box 34. Furthermore, a concealing part is connected to the bottom surface of the tabletop 1 to hide the cable suspended between the cable tray 12 and the cable tray 34. This concealing part is a transition and storage component for the cable from the tabletop 1 to the cable tray 34. The concealing part includes a cable tray 31 fixed to the bottom surface of the tabletop 1. The cable tray 31 is set perpendicular to the cable tray 34, forming an L-shape. The cable storage path is designed with a cable inlet hole 301 on the upper surface of the cable box 31. The inlet hole 301 has a rounded corner design and is used to introduce the cable leading out of the cable hole 12 into the cable box 31. The cable box 31 has multiple cable outlet holes 302 at one end near the cable box 34. The cable is suitable to enter the conductor 36 through the cable outlet holes 302. At the same time, the bottom surface of the cable box 31 has an opening 303, which is an operation window for manually threading cables. This makes it easier for operators to thread the cable from the cable box 31 to the conductor 36, improving the convenience of the wiring operation. Multiple locking parts are connected between the second cable box 34 and the cover plate 35, which are fastening components between the cover plate 35 and the second cable box 34. The locking part includes a mounting base 38 fixed on the side of the second cable box 34. A connecting shaft (not shown in the figure) is transversely movably passed through the mounting base 38. Springs 39 are connected to both ends of the connecting shaft. One end of the spring 39 has a connector 310, and one end of the two sets of connectors 310 is connected to a hanging rod 311. At the same time, a hook part 312 adapted to the hanging rod 311 is fixed on the side of the cover plate 35. The hook part 312 engages with the hanging rod 311 to achieve the closing and locking of the cover plate 35.

[0022] Working Principle: The height adjustment of the electric height-adjustable desk is driven by the lifting assembly 2. After the user sends a command via the switch 13 on the side of the desk 1, the two sets of drive components 22 start synchronously under pulse synchronization control. The output end drives the first bevel gear 23 to rotate, and the first bevel gear 23 meshes with the second bevel gear 26 to transmit power to the lead screw 25, causing the two sets of lead screws 25 to rotate synchronously within the support rod 24. The lead screw 25 is threaded into the sliding seat 28. The sliding seat 28 is limited by the inner wall of the support rod 24 and can only move in the vertical direction, thereby driving the lifting rod 27 to rise and fall smoothly along the guide trajectory of the guide wheel 29. The lifting rod 27 drives the desk 1 to achieve synchronous height adjustment through the load-bearing frame 11 connected to the top, ensuring that the desk 1 always remains horizontal.

[0023] The cable management assembly 3 achieves complete concealment and neatness of the cable throughout the entire process. Desktop cables first pass through the cable management hole 12 of the tabletop 1, then through the inlet hole 301 of the cable management box 31 (operators can assist with cable threading through the opening 303 on the bottom of the cable management box 31). After exiting through the outlet hole 302 of the cable management box 31, the cable is guided by the hollow structure of the conductor 36 and enters the cable management box 34. Multiple sets of cable clamps 37 on the inner wall of the cable management box 34 classify and hold different types of cables to prevent tangling; the cable ends extend to an external socket through the through hole 341 on the bottom of the cable management box 34, completing power supply or data connection. The through hole 341 also provides heat dissipation for the cable. For maintenance, pull the hanging rod 311 to separate it from the hook part 312, allowing the cover 35 to be opened for operation. After operation, the spring 39 drives the hanging rod 311 to return to its original position, locking the cover 35 in place.

[0024] The concealed design solves the problem of exposed cables hanging between the cable routing hole 12 and the cable box 34. The cable box 31, fixed to the bottom of the tabletop 1, is positioned perpendicular to the cable box 34, forming an L-shaped storage path. After the cable is led out from the cable routing hole 12 of the tabletop 1, it first enters the cable box 31 for temporary storage, and then is orderly threaded into the wire connector 36 through the cable outlet hole 302. This eliminates the messy appearance of the suspended cable section and makes the cable transition from the desktop to the inside of the table more neat and safe.

[0025] When the user needs to adjust the table height, the drive component 22 of the lifting assembly 2 operates synchronously, driving the tabletop 1 to rise and fall smoothly through bevel gear transmission and lead screw 25 mechanism. Simultaneously, the cable management assembly 3, including cable box 31, cable box 34, and cable clamp 37, conceals the desktop cables within the table body, preventing tangling or pulling during tabletop 1 adjustment. These two functions—height adjustment and cable concealment—meet the user's personalized needs for table height while ensuring a clean and aesthetically pleasing desktop and electrical safety, achieving efficient, safe, and convenient use of the electric height-adjustable desk.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
