Description

Technical Field

[0001] This utility model relates to the field of conference table technology, and in particular to a conference table with a height-adjustable display screen. Background Technology

[0002] With the intelligent development of modern offices and business meetings, the functionality and integration requirements of conference tables, as core office equipment, are increasing. Traditional conference tables typically employ a fixed structure, with the desktop used only for document placement or simple writing, while electronic devices such as displays and keyboards are often placed as independent peripherals on the desktop or side, resulting in low desktop space utilization and cluttered equipment placement. In recent years, to adapt to the needs of multimedia conferencing and video communication scenarios, some conference tables have begun to integrate height-adjustable display screens. By hiding the display screen under the desktop, it can be raised when needed for human-computer interaction and stored inside the table when not in use, thereby optimizing desktop space. However, existing height-adjustable display screen conference tables still face many technical bottlenecks in practical applications and urgently need improvement.

[0003] Existing height-adjustable conference tables often use a single motor or hydraulic rod for direct drive, lacking a precise guiding mechanism. This leads to problems such as screen wobbling and shifting during lifting, and even component wear or jamming due to uneven force. For example, some solutions connect the support plate with only a single drive rod without side guide rails for limiting movement. When the screen is heavy, lateral shifting during lifting can cause the screen to rub against the edge of the table's through-holes, potentially damaging the screen frame or table structure over time. Furthermore, the connection between the drive unit and the support plate is often a simple hinge or fixed connection, failing to achieve precise positioning. When the screen is raised to the top, it is difficult to form a stable support with the table, posing a safety hazard.

[0004] In traditional height-adjustable conference tables, the power and signal cables for the display screen and keyboard are often exposed through pre-drilled holes in the table body. This not only affects the tidiness of the desktop but also makes them prone to tangling and damage, and even safety issues such as electrical leakage. While some solutions attempt to integrate the cables into the lifting mechanism, they do not solve the problem of dynamic cable connection during the lifting process. When the display screen is lowered and retracted, the cables need to move with the support plate; improper connection methods can easily lead to poor contact or cable breakage. Furthermore, current technology lacks an automatic electrical connection structure, requiring users to manually plug and unplug cables, which is cumbersome and affects meeting efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model discloses a conference table with an integrated wiring harness that allows for unified raising and lowering of the display screen and keyboard.

[0006] This utility model discloses a conference table with a height-adjustable display screen, which includes a table body, a through hole through the table body, and a downward protrusion on the side of the table body near the through hole.

[0007] The lifting mechanism is located below the table body. The lifting mechanism includes a drive device, a guide rail assembly, and a support box. The support box is located below the through hole of the table body and connected to the table body. The guide rail assembly is located on both sides of the support box, and the drive device is located on the support box.

[0008] The support plate is set on the guide rail assembly inside the support box. The side of the support plate near the edge is recessed downward and has a support groove corresponding to the protrusion.

[0009] The display screen includes a fixing rod at its lower part that can be fixedly mounted on a support plate, and a magnetic suction part is provided on the lower side of the display screen.

[0010] The keyboard has one end hinged to the support plate, and a fixing metal part corresponding to the magnetic part is provided on the side of the keyboard away from the support plate.

[0011] The switch is located on the upper part of the table and is electrically connected to the lifting mechanism.

[0012] The driving device includes a driving component and a driving rod mounted on the driving component. The driving component is located on the outside of the support box, and the driving rod passes through the inside of the support box and is connected to the support plate. When the driving component drives the driving rod, it moves the support plate to the uppermost protrusion and abuts against the support slot. When the driving component drives the driving rod, it moves the support plate to the lowermost position and the display screen moves into the support box. The protrusion is provided with a conductive static contact, and the support slot is provided with a conductive moving contact corresponding to the conductive static contact. The power cord is located inside the table body and connected to the conductive static contact. The display screen wiring harness and keyboard wiring harness are located inside the support plate and connected to the conductive moving contact.

[0013] Furthermore, a baffle corresponding to the through hole on the table is provided above the display screen. When the driving component drives the driving rod, it moves the support plate to the bottom and the display screen moves into the support box. The baffle is set in the through hole on the table.

[0014] Furthermore, the guide rail assembly includes a guide rail body vertically arranged on both sides of the support box, and sliders arranged on both sides of the support plate and slidingly engaged with the guide rail body. The sliders slide up and down along the guide rail body to drive the support plate to rise and fall.

[0015] Furthermore, the driving component can be any one of a motor, hydraulic cylinder, or pneumatic cylinder, and the driving rod is a lead screw or telescopic rod connected to the output end of the driving component. The driving rod is connected to the support plate by a threaded fit or a sliding fit.

[0016] Furthermore, the magnetic attraction part is a magnet located on the lower side of the display screen, and the fixing metal is an iron sheet or iron alloy sheet that magnetically engages with the magnet. The magnetic connection position between the magnet and the fixing metal corresponds to the edge of the keyboard away from the support plate.

[0017] Furthermore, the keyboard is hinged to the support plate via a hinge or a damped pivot, allowing the keyboard to flip upwards around the hinge point to fit against the bottom of the display screen, or flip downwards to be flush with the surface of the support plate.

[0018] Furthermore, the edge of the baffle is provided with a sealing strip, which abuts against the inner wall of the through hole in the table body, and the upper surface of the baffle is flush with the upper surface of the table body.

[0019] Beneficial effects:

[0020] This invention utilizes a synergistic design of a lifting mechanism and a magnetic hinge structure to achieve concealed storage and quick access for the display screen and keyboard. While maintaining a flat conference table surface, it effectively saves space and enhances equipment integration.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions in the specific embodiments of the present invention will be clearly and completely described below.

[0028] This utility model discloses a conference table 100 capable of raising and lowering a display screen 14. It includes a table body 11 with a through hole, and a downwardly protruding portion 111 on the lower side of the table body 11 near the through hole. A raising mechanism 12 is located below the table body 11 and includes a drive device 121, a guide rail assembly 122, and a support box 123. The support box 123 is located below the through hole of the table body 11 and connected to the table body 11. The guide rail assembly 122 is located on both sides of the support box 123, and the drive device 121 is mounted on the support box 123. A support plate 13 is mounted on the guide rail assembly 122 inside the support box 123, and a support groove corresponding to the protruding portion 111 is recessed downwards on the side of the support plate 13 near its edge. The display screen 14 includes a fixing rod at its lower side that can be fixedly mounted on the support plate 13, and a magnetic suction portion 141 is provided on the lower side of the display screen 14. Keyboard 15, one end of which is hinged to the support plate 13, and a fixing metal 151 corresponding to the magnetic part 141 is provided on the side of the keyboard 15 away from the support plate 13. Switch 16, which is located on the upper part of the table body 11, is electrically connected to the lifting mechanism 12. The driving device 121 includes a driving component 1211 and a driving rod 1212 disposed on the driving component 1211. The driving component 1211 is disposed on the outside of the support box 123, and the driving rod 1212 passes through the inside of the support box 123 and is connected to the support plate 13. When the driving component 1211 drives the driving rod 1212, it causes the support plate 13 to move to the uppermost protrusion 111, which abuts against the support slot. When the driving component 1211 drives the driving rod 1212, it causes the support plate 13 to move to the lowermost position, where the display screen 14 moves into the support box 123. The protrusion 111 is provided with a conductive static contact, and the support slot is provided with a conductive moving contact corresponding to the conductive static contact. The power cord is disposed inside the table body 11 and connected to the conductive static contact. The display screen 14 wiring harness and the keyboard 15 wiring harness are disposed inside the support plate 13 and connected to the conductive moving contact. The other side of the power cord extends through to the outside of the table body 11 to connect to external circuitry. The power cord is a common type of electrical wire.

[0029] This utility model features a lifting mechanism 12 installed under the table body 11, allowing the display screen 14 to rise and fall along the guide rail assembly 122 with the support plate 13. When the display screen 14 rises to the top, the protrusion 111 of the table body 11 abuts against the support slot of the support plate 13, thus providing stable support for the display screen 14. Furthermore, the electrical connection between the protrusion 111 and the conductive contacts in the support slot automatically connects the power cord to the wiring harnesses of the display screen 14 and keyboard 15, preventing exposed cables from becoming tangled and messy, ensuring a clean desktop while improving electrical safety. When the display screen 14 descends into the support box 123, it can be hidden under the through hole of the table body 11, effectively saving meeting space and meeting the needs of multi-functional desktop use. The keyboard 15 is connected to the support plate 13 via a hinge. The fixed metal 151 on the side away from the support plate 13 can be magnetically attached to the lower magnetic part 141 of the display screen 14, allowing the keyboard 15 to be stored close to the lower side of the display screen 14 when not in use, avoiding taking up desktop space. When in use, it can be flipped onto the surface of the support plate 13 to form an operating plane, enabling human-computer interaction with the display screen 14. This design, through the linkage of magnetic attachment and hinge, balances convenient storage with stable use. The magnetic connection also ensures the keyboard 15 is fixed in position, improving the smoothness of meeting operations. A power outlet for external power supply is also provided on one side of the table 11.

[0030] The drive unit 121 includes a drive component 1211 and a drive rod 1212. The drive component 1211 is a combination of a servo motor and a ball screw or a stepper motor and a trapezoidal screw. The drive rod 1212 is a screw shaft connected to the motor via a coupling. A motor mounting base is provided on the outside of the support box 123. The conductive stationary contacts of the protrusion 111 are spring-loaded pins, and the conductive moving contacts in the support slot are metal springs. When in contact, the contact area is ensured by spring pressure, and the contact surface is silver-plated to prevent oxidation. A wire groove is opened in the support plate 13, and the wire harness is connected via a rotary joint or cable chain. During lifting, the wire harness moves synchronously with the support plate 13 to avoid pulling. An overload protector is provided in the motor circuit. When the display screen 14 is obstructed, the motor automatically stops. The conductive contacts are equipped with a short-circuit protection circuit. The motor is connected to the switch 16 via a relay module to receive forward and reverse signals to achieve lifting control. The lifting speed is adjusted by the motor driver. The fixing rod and support plate 13 are connected by a flange and bolts. The flange is welded to the bottom of the fixing rod and fixed to the support plate 13 with four M6 bolts to ensure vertical installation accuracy. The keyboard 15 is hinged to the support plate 13 via a damping hinge, which can adjust the tilt angle. The magnetic part 141 uses a neodymium iron boron magnet, and the fixing metal 151 is an iron sheet. The magnetic strength needs to be verified by experiments. When the drive rod 1212 is activated to move the support plate 13 downward, the keyboard 15 is adjusted so that the keyboard 15 is fixed to the display screen 14 via the magnetic part 141.

[0031] In one implementation, a baffle 142 corresponding to the through hole on the table body 11 is provided above the display screen 14. When the driving member 1211 drives the driving rod 1212, causing the support plate 13 to move to the lowest position and the display screen 14 to move into the support box 123, the baffle 142 is positioned in the through hole on the table body 11. When the display screen 14 descends into the support box 123, the baffle 142 is embedded in the through hole of the table body 11, which keeps the upper surface of the table body 11 flat and continuous, avoiding the formation of depressions or gaps in the through hole. This not only improves the overall aesthetics of the conference table 100, but also prevents debris from falling into the through hole and affecting the operation of the lifting mechanism 12. At the same time, it eliminates the obstruction caused by the unevenness of the desktop to the placement of documents and the movement of items, ensuring the convenience and safety of the desktop.

[0032] In one implementation, the guide rail assembly 122 includes a guide rail body 1221 vertically disposed on both sides of the support box 123, and a slider 1222 disposed on both sides of the support plate 13 and slidably engaged with the guide rail body 1221. The slider 1222 slides up and down along the guide rail body 1221 to drive the support plate 13 to rise and fall. The guide rail assembly 122 adopts a sliding engagement structure between the guide rail body 1221 and the slider 1222, which can accurately guide the rising and falling movement of the support plate 13, ensuring that the display screen 14 maintains vertical and stable movement during the rising and falling process, avoiding shaking or deviation. This not only improves the stability of the rising and falling of the display screen 14, but also prevents component wear or jamming caused by deviation of the movement trajectory, thus extending the service life of the equipment.

[0033] In one implementation, the drive component 1211 can be any one of a motor, hydraulic cylinder, or pneumatic cylinder, and the drive rod 1212 is a lead screw or telescopic rod connected to the output end of the drive component 1211. The drive rod 1212 is connected to the support plate 13 by a threaded fit or a sliding fit. The use of a motor, hydraulic cylinder, or pneumatic cylinder for the drive component 1211, combined with the design of the drive rod 1212 (lead screw or telescopic rod), allows the lifting mechanism 12 of the conference table 100 to flexibly select its power source according to different usage scenarios and needs. Motor drive offers precise controllability, hydraulic cylinder drive provides powerful thrust, and pneumatic cylinder drive enables rapid response, meeting diverse industrial production or daily use needs and improving the applicability and flexibility of the equipment. The drive rod 1212 is connected to the support plate 13 by a threaded or sliding fit, which can efficiently convert the power of the drive component 1211 into the linear motion of the support plate 13. The threaded fit can achieve precise position control and self-locking function, ensuring the stability of the display screen 14 during the lifting process; the sliding fit can provide smooth motion transmission and reduce energy loss. Both connection methods can ensure that the lifting mechanism 12 operates smoothly and reliably, extend the service life of the equipment, and reduce maintenance costs.

[0034] In one implementation, the magnetic suction part 141 is a magnet disposed on the lower side of the display screen 14, and the fixing metal 151 is an iron sheet or iron alloy sheet that magnetically engages with the magnet. The magnetic connection position between the magnet and the fixing metal 151 corresponds to the edge of the keyboard 15 away from the support plate 13. The magnetic suction part 141 adopts a magnetic engagement structure between the magnet and the iron sheet or iron alloy sheet, eliminating the need for additional bolts or clips. This allows for quick assembly and disassembly of the keyboard 15 and the lower side of the display screen 14, simplifying the component assembly process and avoiding the problem of screw loosening caused by long-term use in traditional mechanical connections. This ensures that the keyboard 15 can be securely attached to the display screen 14 when stored, improving the overall structural reliability of the device. By aligning the magnetic attraction of the magnet with the fixed metal 151 at the edge of the keyboard 15 away from the support plate 13, a stable limiting effect can be formed by the magnetic attraction when the keyboard 15 is flipped upwards, keeping the keyboard 15 in contact with the lower side of the display screen 14 and preventing displacement due to shaking during storage. When in use, the keyboard 15 can be easily detached from the magnetic connection and flipped to the operating plane. This design, through the linkage of magnetic positioning and hinged flipping, balances compact storage with ease of use, optimizing the human-computer interaction experience of meeting operations.

[0035] In one implementation, the keyboard 15 is hinged to the support plate 13 via a hinge or a damping hinge. The keyboard 15 can be flipped upwards around the hinge point to fit against the lower side of the display screen 14, or flipped downwards to be flush with the surface of the support plate 13. This hinge or damping hinge design allows the keyboard 15 to be flexibly flipped around the hinge point. When flipped upwards, it fits snugly against the lower side of the display screen 14, achieving a concealed storage of the keyboard 15 and preventing it from being exposed and occupying desktop space. Simultaneously, the magnetic part 141 and the fixing metal 151 form a double fixation, ensuring that the keyboard 15 will not shift due to shaking when stored, effectively improving the tidiness and space utilization of the conference table 100.

[0036] As one implementation method, the edge of the baffle 142 is provided with a sealing strip, which abuts against the inner wall of the through hole in the table body 11. The upper surface of the baffle 142 is flush with the upper surface of the table body 11. The sealing strip on the edge of the baffle 142 abuts tightly against the inner wall of the through hole in the table body 11, forming a sealed barrier when the display screen 14 is stored. This effectively prevents dust, debris, and liquids from falling into the support box 123 through the through hole, avoiding contamination or damage to components such as the display screen 14 and the drive device 121. At the same time, it reduces the accumulation of external dust in the lifting mechanism 12, reduces the risk of mechanical wear, and extends the maintenance cycle and service life of the equipment. The design of the upper surface of the baffle 142 being flush with the upper surface of the table body ensures that the conference table 100 maintains a completely flat desktop when the display screen 14 is hidden. This eliminates the obstruction of items or the risk of people bumping into things caused by the recessed through hole, while ensuring that the desktop can be used normally for document display, writing, and other scenarios, maintaining the complete functionality of the conference table 100.

[0037] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
