Description

Technical Field

[0001] This application relates to the technical field of industrial production, and in particular to a concealed lifting operating platform. Background Technology

[0002] In industrial production, especially in hazardous or harsh environments, remote operation or unmanned automated control of field equipment is often required from a central control room. The central control room is equipped with a console and various operating devices, such as computer monitors, touchscreens, keyboards, remote operation buttons, and instruments, for monitoring and operating production equipment. During unmanned automated operation, these operating devices are often not in use but remain on the console, affecting the aesthetics and overall tidiness of the central control room.

[0003] Currently, existing control panels are mainly divided into fixed control panels and lifting control panels. Fixed control panels fix the equipment to the tabletop and cannot be raised, lowered, or moved; while lifting control panels can adjust the height of the tabletop, their minimum lowering height is still relatively high, making it impossible to completely hide the equipment inside the control panel, and the equipment is still partially exposed when not in use.

[0004] However, the existing control panel technology has obvious drawbacks: because the operating equipment (such as the monitor screen) is exposed on the control panel for a long time, it is easily damaged by accidental bumps, scratches or dust accumulation, which can lead to equipment damage or shortened lifespan; at the same time, the inability to completely hide the equipment also affects the aesthetics and uniformity of the control room, and fails to create a truly unmanned operating atmosphere. Utility Model Content

[0005] This application provides a concealed lifting operating platform, which can at least partially solve the above-mentioned technical problems.

[0006] This application provides a concealed lifting operating platform, which adopts the following technical solution: A concealed lifting control panel includes a control panel cabinet, wherein a concealed space is provided inside the control panel cabinet and an opening is provided on the control panel cabinet. A cover plate is movably connected to the opening; The control panel cabinet is equipped with a lifting mechanism, which includes a lifting platform panel that slides vertically on the control panel cabinet and a lifting component disposed in the control panel cabinet. The lifting component is connected to the lifting platform panel and is used to drive the lifting platform panel to slide vertically.

[0007] By adopting the above technical solution, a hidden space is created inside the control panel cabinet, with a cover plate movably connected to the opening. When needed, the lifting mechanism is activated, and the lifting component raises the lifting platform panel vertically from the hidden space, revealing the control panel surface through the opening. When not in use, the lifting component lowers the lifting platform panel back into the hidden space, the cover plate closes the opening, and the control panel surface is completely hidden, achieving complete concealment and lifting functions for the control panel. When not in use, the lifting platform panel and equipment are completely hidden inside the cabinet, and the cover plate is closed, effectively reducing accidental bumps, scratches, or dust accumulation on the equipment, extending its lifespan. At the same time, the concealed control panel surface is flat and aesthetically pleasing, improving the overall cleanliness and aesthetics of the control room and creating a truly unmanned operating environment. The lifting function allows users to adjust the height of the control panel as needed, improving operational flexibility.

[0008] Optionally, the lifting assembly includes a slide rail, a lifting frame, and a drive component. Two sets of slide rails are arranged vertically. The lifting frame is connected to the lifting platform panel and slides in cooperation with the slide rail. The drive component is disposed on the slide rail and connected to the lifting frame.

[0009] By adopting the above technical solution, the lifting assembly includes a slide rail, a lifting frame, and a drive component. Two sets of slide rails are arranged vertically. The lifting frame is connected to the lifting platform panel, with grooves at both ends to engage with the slide rails. The drive component is mounted on the slide rails and connected to the lifting frame. When the drive component operates, it drives the lifting frame to slide along the slide rails, thereby raising and lowering the lifting platform panel. The cooperation between the slide rails and grooves ensures the stability and smoothness of the lifting process, preventing the lifting platform panel from shaking or jamming during lifting, thus improving the reliability of the lifting. The drive component provides automated power, simplifying operation; it also increases the mechanical stability of the lifting mechanism, making the lifting action smoother and more precise, and further protecting the equipment from vibration or impact.

[0010] Optionally, the driving component includes a geared motor, a drive gear, and a rack. The rack is vertically mounted on one of the slide rails. The geared motor is mounted on the lifting frame. The drive gear is keyed to the output shaft of the geared motor and rotates at one end of the lifting frame. The drive gear meshes with the rack.

[0011] By adopting the above technical solution, the driving components include a geared motor, a drive gear, and a rack. The rack is vertically mounted on one of the slide rails, the geared motor is mounted on the lifting frame, and the drive gear is keyed to the output shaft of the geared motor and meshes with the rack. When the geared motor is working, the drive gear rolls along the rack, driving the lifting frame to rise and fall along the slide rails. The gear and rack transmission provides precise lifting control, and the geared motor ensures controllable lifting speed, avoiding impacts or equipment damage caused by rapid lifting. This transmission method is highly efficient, low-noise, and has a long service life, making it suitable for industrial environments. It provides a more precise and reliable driving mechanism, allowing for accurate control of the lifting position and enhancing the smoothness and safety of the lifting process.

[0012] Optionally, both slide rails are provided with racks, and the other end of the lifting frame is rotatably connected to a driven gear, which meshes with the other rack. The driven gear and the driving gear are coaxially connected through a connecting shaft.

[0013] By adopting the above technical solution, racks are installed on both slide rails, and a driven gear is rotatably connected to the other end of the lifting frame. The driven gear meshes with another rack, and the driven gear and the driving gear are coaxially connected through a connecting shaft. When the driving gear rotates, it drives the driven gear to rotate synchronously through the connecting shaft, so that the two racks drive the lifting frame simultaneously. The double rack and double gear design provides symmetrical driving force, enabling the two sides of the lifting frame to move synchronously, preventing the lifting platform panel from tilting or jamming, and improving the balance and stability of the lifting. It reduces the off-center load problem of single-point drive, reduces component wear, extends the service life of the lifting mechanism, and further enhances the synchronization and reliability of the lifting.

[0014] Optionally, the cover plate includes a front cover plate and a rear cover plate. The cover plate slides on the operating table cabinet via a sliding mechanism. The sliding mechanism includes a track, a sliding component, and a driving component. The track includes a first guide rail, a second guide rail, and a third guide rail, which are connected sequentially. The first guide rail is horizontally positioned at the opening. The second guide rail is angled to the first guide rail, and the third guide rail is angled to the second guide rail. The front cover plate and the rear cover plate are connected via the sliding component and slide on the track. The cover plate closes or opens the opening via the track. The driving component is connected to the cover plate and is used to drive the cover plate to slide along the track.

[0015] By adopting the above technical solution, the cover plate includes a front cover plate and a rear cover plate, which slide on the operating table cabinet via a sliding mechanism. The sliding mechanism includes a track, a sliding component, and a drive component. The track is composed of a first guide rail, a second guide rail, and a third guide rail connected in sequence. The first guide rail is horizontally set at the opening, and the second and third guide rails are set at an angle to each other. The sliding component connects the front and rear cover plates and slides on the track. The drive component is connected to the cover plate and drives it to slide along the track, realizing the closing or opening of the opening. The sliding mechanism allows the cover plate to open and close smoothly. The track design allows the cover plate to move along a specific path when open, avoiding occupying extra space and improving space utilization. The separate design of the front and rear cover plates makes the cover plate movement more flexible. It realizes the automatic opening and closing of the cover plate and works in coordination with the lifting mechanism: when the lifting platform panel is raised, the cover plate automatically opens; when it is lowered, the cover plate automatically closes, achieving seamless concealment and improving the overall convenience and aesthetics of operation.

[0016] Optionally, the sliding assembly includes a first link, a second link, a third link, a fourth link, and pulleys. The first link is disposed on the front cover plate, and the second link is disposed on the rear cover plate. Pulleys are provided at both ends of the first link and at the end of the second link closest to the first link. A sliding groove is provided on the track, and the pulleys slide within the sliding groove. The third link is located between the second link and the first link, and both ends of the third link are rotatably connected to the first link and the second link, respectively. The fourth link is rotatably connected to the end of the second link away from the first link, and the driving assembly is connected to the fourth link.

[0017] By adopting the above technical solution, the sliding assembly includes a first link (set on the front cover), a second link (set on the rear cover), a third link (connecting the first and second links), a fourth link (rotatably connected to the end of the second link away from the first link), and pulleys. Pulleys are provided at both ends of the first link and at the end of the second link closest to the first link, and the pulleys slide within the grooves of the track. The drive assembly is connected to the fourth link. When the drive assembly is working, it drives the second link to move via the fourth link, and then drives the first link to move via the third link, causing the front and rear covers to slide along the track. The linkage mechanism converts the linear motion of the driving force into a smooth curved motion of the cover. The pulleys reduce friction within the grooves, making the cover movement easy. The third link ensures synchronous movement of the front and rear covers, preventing misalignment or jamming. It provides more precise cover control, ensuring that the cover completely leaves the opening area when opened and tightly covers when closed, enhancing sealing and protection. The linkage design allows the cover to complete complex movements within a limited space, making it suitable for compact cabinets.

[0018] Optionally, the drive assembly includes a fixed rail, a sliding frame, a drive motor, a drive gear, and a fixed rack. The fixed rail is fixed inside the control panel cabinet and is parallel to and fixed to one side of the third guide rail. The sliding frame slides on the fixed rail. The fixed rack is fixed on the fixed rail. The drive motor is mounted on the sliding frame. The drive gear is mounted on the output shaft of the drive motor and meshes with the fixed rack.

[0019] By adopting the above technical solution, when the drive motor is working, the drive gear moves along the fixed rack, driving the sliding frame to move, which in turn drives the cover plate to move through the fourth linkage. The gear and rack transmission provides smooth and precise linear motion. The drive motor controls the moving speed and position of the cover plate, realizing automated opening and closing. The fixed rail guides the sliding frame to ensure the correct direction of movement and prevent the cover plate from deviating. Reliable drive of the cover plate is achieved, forming a linkage system with the lifting mechanism, which improves the overall level of automation. The drive component has a compact structure, is easy to maintain, and is suitable for industrial environments.

[0020] Optionally, both the drive gear and the fixed rack are provided in two sets, the drive motor meshes with one of the drive gears, and the two drive gears are connected by a transmission shaft.

[0021] By adopting the above technical solutions, the dual-drive gear design provides symmetrical driving force, prevents the sliding frame from tilting, ensures the cover plate moves smoothly and synchronously, and reduces the wear and failure risk of single-point drive; it improves the reliability and lifespan of the drive system, and can maintain stability even under high load; it further enhances the balance and durability of the cover plate drive, echoing the dual-gear design of the lifting mechanism to form a unified and robust drive system.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. When not in use, the lifting platform panel and equipment are completely hidden inside the cabinet with the cover closed, effectively preventing the equipment from being accidentally bumped, scratched, or accumulating dust, thus extending the equipment's lifespan. At the same time, the concealed operating platform surface is flat and aesthetically pleasing, enhancing the overall cleanliness and aesthetics of the control room and creating a truly unmanned operating atmosphere. The lifting function allows users to adjust the height of the operating platform as needed, improving the flexibility of use. 2. The double rack and pinion design provides symmetrical driving force, enabling synchronous movement on both sides of the lifting frame, preventing the lifting platform panel from tilting or jamming, and improving the balance and stability of the lifting; it also reduces the off-center load problem of single-point drive, reduces component wear, extends the service life of the lifting mechanism, and further enhances the synchronization and reliability of the lifting. 3. It achieves reliable drive of the cover plate, forming a linkage system with the lifting mechanism, which improves the overall level of automation; the drive component has a compact structure, is easy to maintain, and is suitable for industrial environments.

[0025] The following combination Figures 1 to 6 This application will be described in further detail.

[0026] Reference Figures 1 to 6This utility model provides a concealed lifting control panel for use in industrial production control rooms, enabling the concealment and lifting functions of operating equipment. The control panel mainly includes a control cabinet 100, a lifting mechanism 300, a cover plate 200 structure, a sliding mechanism 400, and a control system. The control cabinet 100 has a concealed space within it, with an opening 131 at the top. The lifting mechanism 300 includes a lifting platform panel 310 and a lifting assembly 320. The lifting platform panel 310 slides vertically within the concealed space via the lifting assembly 320. The cover plate 200 is movably connected to the opening 131, and the sliding mechanism 400 closes or opens the opening 131. In use, when equipment needs to be operated, the cover plate 200 opens the opening 131, and the lifting mechanism 300 raises the lifting platform panel 310 to be flush with the surface of the control cabinet 100. When not in use, the lifting mechanism 300 lowers the lifting platform panel 310 back into the concealed space, and the cover plate 200 closes the opening 131, achieving complete concealment.

[0027] The control cabinet 100 forms the outer shell structure of the entire control panel, with a hidden space inside to accommodate the lifting platform panel 310 and related equipment. The control cabinet 100 includes components such as a frame 110, fully opening cabinet doors 120, and a control surface 130. The frame 110 is welded from columns and beams, with a base plate at the bottom and a back plate at the back. The fully opening cabinet doors 120 include three doors 120, which are installed on the remaining three vertical surfaces of the frame 110. The doors 120 can be opened for convenient installation and maintenance of the internal equipment. The control surface 130 is installed on the top surface, with an opening 131 formed on this surface. The shape of the opening 131 matches the lifting platform panel 310 so that the lifting platform panel 310 is exposed through the opening 131 when raised.

[0028] The lifting mechanism 300 is installed in the hidden space of the control panel cabinet 100, including the lifting panel 310 and the lifting component 320; the lifting panel 310 is used to place computer monitors, touch screens, keyboards, remote operation buttons, instruments and meters and other equipment, and the lifting component 320 drives the lifting panel 310 to slide vertically.

[0029] The lifting assembly 320 includes a slide rail 321, a lifting frame 322, and a drive component 323. Two sets of slide rails 321 are vertically arranged and fixed to the upper and lower inner walls of the control panel cabinet 100, respectively. The lifting frame 322 is connected to the lifting platform panel 310. Slide grooves are correspondingly formed at both ends of the lifting frame 322, which cooperate with the slide rails 321 to allow the lifting frame 322 to slide up and down along the slide rails 321. The drive component 323 is mounted on the slide rails 321 and connected to the lifting frame 322, used to drive the lifting frame 322 to move.

[0030] The drive unit 323 includes a geared motor 324, a drive gear 325, and a rack 326. The rack 326 is vertically mounted on one of the slide rails 321. The geared motor 324 is mounted on the lifting frame 322. The drive gear 325 is keyed to the output shaft of the geared motor 324 and rotates at one end of the lifting frame 322. The drive gear 325 meshes with the rack 326. When the geared motor 324 is working, the drive gear 325 rolls along the rack 326, driving the lifting frame 322 to rise and fall along the slide rail 321.

[0031] In other embodiments, to enhance the balance and stability of the lifting mechanism, racks 326 are provided on both slide rails 321. A driven gear 327 is rotatably connected to the other end of the lifting frame 322. The driven gear 327 meshes with another rack 326, and the driven gear 327 is coaxially connected to the driving gear 325 via a connecting shaft 328. Thus, when the driving gear 325 rotates, it drives the driven gear 327 to rotate synchronously via the connecting shaft 328, achieving synchronous drive of the two racks 326 and preventing the lifting platform panel 310 from tilting.

[0032] The cover plate 200 is movably connected to the opening 131 of the control cabinet 100 and is used to close or open the opening 131. The cover plate 200 can be moved by sliding, rotating or other means. In this embodiment, the preferred way for the cover plate 200 to move is sliding. The cover plate 200 includes a front cover plate 210 and a rear cover plate 220, which slide on the control cabinet 100 through the sliding mechanism 400.

[0033] The sliding mechanism 400 includes two sets of parallel tracks 410, a sliding component 420, and a driving component 430. The track 410 includes a first guide rail 411, a second guide rail 412, and a third guide rail 413, which are connected in sequence and integrally formed. The first guide rail 411 is horizontally positioned at the opening 131. The second guide rail 412 is angled to the first guide rail 411, and the third guide rail 413 is angled to the second guide rail 412, forming a three-section track 410 structure. The third guide rail 413 is located on one side of the opening 131, and the third guide rail 413 forms an acute angle with respect to the plane of the operating table 130. The second guide rail 412 also forms an acute angle with respect to the plane of the operating table 130, and the angle between the third guide rail 413 and the operating table 130 is greater than the angle between the second guide rail 412 and its plane. The axis of the first guide rail 411 is parallel to the operating table 130. The sliding assembly 420 connects the front cover plate 210 and the rear cover plate 220 and slides on the track 410. The driving assembly 430 is connected to the cover plate 200 through the sliding assembly 420 and is used to drive the cover plate 200 to slide along the track 410.

[0034] The sliding assembly 420 includes a first link 421, a second link 422, a third link 423, a fourth link 424, and pulleys 425. Two first links 421 are mounted on the front cover plate 210, located on the left and right sides of the front cover plate 210, respectively. Two second links 422 are mounted on the rear cover plate 220, located on both sides of the rear cover plate 220. Pulleys 425 are mounted at both ends of the first link 421 and at the ends of the second link 422 closest to the first link. A sliding groove is provided on the track 410, and the pulleys 425 slide within the sliding groove. The third link 423 is located between the second link 422 and the first link 421, with both ends rotatably connected to the first link 421 and the second link 422, respectively. The fourth link 424 is rotatably connected to the end of the second link 422 furthest from the first link 421. The drive assembly 430 is connected to the fourth link 424.

[0035] The drive assembly 430 includes a fixed rail 431, a sliding frame 432, a drive motor 433, a drive gear 434, and a fixed rack 435. Two fixed rails 431 are fixed inside the control panel cabinet 100, corresponding to each other and parallel to one side of the third guide rail 413. The sliding frame 432 slides on the fixed rail 431, the fixed rack 435 is fixed on the fixed rail 431, the drive motor 433 is mounted on the sliding frame 432, and the drive gear 434 is mounted on the output shaft of the drive motor 433 and meshes with the fixed rack 435. When the drive motor 433 operates, the drive gear 434 moves along the fixed rack 435, driving the sliding frame 432 to move, thereby moving the cover plate 200 via the fourth connecting rod 424.

[0036] In other embodiments, to ensure smooth driving, two sets of drive gears 434 and fixed racks 435 are provided. The drive motor 433 meshes with one of the drive gears 434, and the two drive gears 434 are connected by a transmission shaft 436 to achieve synchronous driving.

[0037] In other embodiments, the control system is used to control the coordinated operation of the lifting mechanism 300 and the cover plate 200. The control system includes components such as push-button switches, limit switches, and a control board. The push-button switches are installed on the door panel of the operating console cabinet 100 for easy operation. The limit switches include a lower limit switch and an upper limit switch, which are respectively installed at relevant positions on the lifting mechanism 300 and the cover plate 200 structure to detect the extreme positions of the lifting platform panel 310 and the cover plate 200. The control board is fixed to the bottom plate of the operating console cabinet 100 and contains a control chip and power supply for processing signals and controlling motor operation.

[0038] The control system implements a one-button lifting function: When the lower button is pressed, the lifting mechanism 300 automatically lowers, and the lifting platform panel 310 stops after triggering the lower limit switch at its lowest position; subsequently, the cover plate 220 automatically rises, and the cover plate 200 rises to its highest position, flush with the operating table surface 130, before stopping after triggering the upper limit switch. When the upper button is pressed, the cover plate 200 automatically lowers, and the cover plate 200 stops after triggering the lower limit switch at its lowest position; subsequently, the lifting mechanism 300 automatically rises, and the lifting platform panel 310 rises to its highest position, flush with the operating table surface 130, before stopping after triggering the upper limit switch.

[0039] In other embodiments, the anti-pinch system is integrated into the control system to prevent operator injury during lifting or movement of the cover 200. When the lifting platform panel 310 or cover 200 encounters resistance (such as being caught by a foreign object) during rising or falling, the control system detects a change in current or detects resistance through a sensor, automatically reverses the movement a certain distance, and then attempts to move again. This ensures operational safety and avoids accidental injury.

[0040] In use, the operator issues commands via a button switch. When the equipment needs to be operated, pressing the "up" button causes the cover 200 to automatically lower, opening the opening 131. Then, the lifting mechanism 300 automatically rises, raising the lifting platform 310 to be flush with the operating surface 130, allowing the operator to use the equipment. When not in use, pressing the "down" button causes the lifting mechanism 300 to automatically lower, returning the lifting platform 310 to its concealed position. Then, the cover 220 automatically rises, closing the opening 131 and restoring the operating surface 130 to a flat state.

[0041] The concealed lifting control panel of this invention has the following technical advantages: it completely conceals the operating equipment; when not in use, the equipment is protected in the hidden space, avoiding accidental bumps, scratches, and dust accumulation, thus extending the equipment's lifespan; the control panel has a clean and aesthetically pleasing appearance, improving the overall environment of the control room and creating an atmosphere of unmanned operation; the lifting and cover plate 200 operates smoothly and reliably, with the gear and rack 326 and track 410 design ensuring the accuracy and synchronization of movement; the control system enables one-button operation, making it simple and easy to use, and the anti-pinch system ensures safety; the structure is compact, with high space utilization, making it suitable for use in industrial control rooms.

[0042] The above are all 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.
