Description

Technical Field

[0001] This invention relates to the field of multimedia display technology, and in particular to an interactive multimedia integrated display device for exhibition halls. Background Technology

[0002] Interactive multimedia integrated display devices for exhibition halls refer to multi-technology integrated with multimedia digital technology in exhibition space. These devices combine sensors, motion recognition, AR / VR, holographic projection, touch screens, and intelligent control, and integrate various technologies such as video, audio, images, and animations through structured wiring and software system integration. This allows visitors to interact with exhibits and content in real time through touch, gestures, voice, and motion sensing, breaking the traditional "static viewing" mode and creating an immersive and participatory exhibition experience. These devices are widely used in museums, planning halls, corporate exhibition halls, and other similar settings.

[0003] However, in existing technologies, most multimedia display devices in exhibition halls are fixed installations, and the height and number of screens cannot be flexibly adjusted, making it difficult to adapt to different scenario needs. Heat dissipation and protection functions are independent; open ventilation holes allow dust to easily enter and cause components to overheat; while complete enclosures prevent dust but hinder heat dissipation, making it difficult to simultaneously meet the dual requirements of sealing and ventilation. For example, a mobile multimedia display device disclosed in patent CN221995742U, although capable of storing and protecting the display screen, still suffers from these defects: the height adjustment of the display screen lacks precise vertical guidance and limits, relying solely on hinged and flipped baffles for protection, making it prone to swaying and shifting during lifting and lowering, and failing to guarantee height consistency when multiple screens are synchronized; the ventilation holes lack an automatic opening and closing linkage structure, and the transparent protective plate only provides physical shielding, leaving dust accumulation and overheating problems unresolved; furthermore, the device is only a single-screen structure, unable to flexibly select between single-screen or multi-screen display, resulting in insufficient overall flexibility and operational stability.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0005] To overcome the technical defects of existing technologies, this invention provides an interactive multimedia integrated display device for exhibition halls, which features flexible switching between single-screen and multi-screen display, precise vertical bar guidance to ensure smooth lifting, and automatic opening and closing of heat dissipation holes in a closed structure, extending for heat dissipation and retracting for dust prevention, thus taking into account both protection and heat dissipation needs.

[0006] The technical solution adopted in this invention is as follows: It includes a housing, a drive structure, multiple display screens, a vertical frame, and a closed structure.

The sealing plate corresponds to the heat dissipation holes.

[0007] Preferably, in order for the threaded rod to rotate and drive the threaded block to rise and fall, the adjusting block drives the circumferentially distributed connecting plates to rise and fall synchronously, so as to achieve uniform height adjustment of the display screen, allowing the screen to slide on the vertical frame and extend out of the box for display. The adjusting component includes a threaded rod and a threaded block. The threaded rod is rotatably installed on the inner wall of the bottom end of the box through the rotating joint. The threaded block is threadedly fitted on the threaded rod. An adjusting block is fixedly installed on the top of the threaded block. The adjusting block is fitted on the threaded rod. The connecting plate is fixedly connected to the adjusting block.

[0008] Preferably, in order to provide stable support for the threaded rod through the support frame, the drive motor drives the threaded rod to rotate, causing the threaded block to rise and fall along the rod. This, in turn, drives the circumferentially distributed connecting plates through the adjusting block to synchronously raise and lower the display screen, achieving electric and automated height adjustment. The adjusting assembly also includes a support frame, which is fixed to the inner wall of the bottom of the housing. One end of the threaded rod is rotatably inserted into the top of the support frame, and a drive motor is fixedly installed on the top of the support frame. One end of the threaded rod is fixedly connected to the output shaft of the drive motor.

[0009] Preferably, in order to restrict the rotational freedom of the threaded block by the limiting slide rod, so that it can only move up and down in the vertical direction, and to prevent the threaded block from rotating with the threaded rod, and to ensure that the connecting plate drives the display screen to move up and down smoothly, thereby improving the adjustment accuracy and operation stability, the limiting slide rod is fixedly installed on the inner wall of the top of the support frame, and one end of the threaded block is slidably fitted on the limiting slide rod.

[0010] Preferably, in order to enable the adjusting cylinder to drive the pin block to insert into or disengage from the pin hole on the side wall of the pin seat, control the locking and separation of the connecting plate and the vertical frame, realize the quick disassembly and replacement of the display screen, and improve maintenance convenience and display flexibility, the pin connection assembly further includes a positioning seat, the mounting block and the pin seat. The positioning seat is fixed to the top of the connecting plate, and an adjusting cylinder is fixedly installed on the positioning seat. The telescopic end of the adjusting cylinder is fixedly connected to the pin block, and the pin block corresponds to the pin hole opened on the side wall of the pin seat.

[0011] Preferably, in order to enable the mounting block to engage with the vertical slot of the vertical frame, providing guidance and limiting for the vertical bar, allowing the display screen to slide smoothly up and down along the vertical bar, preventing swaying and deviation, and ensuring smooth lifting and precise positioning, the pin seat is fixed to the side wall of the vertical bar, the vertical frame has a vertical slot, and the vertical bar is slidably connected to the vertical slot through the mounting block.

[0012] Preferably, in order to enable the lateral moving column to slide on the lateral fixed plate and drive the closing plate to cover or expose the heat dissipation hole, the return spring provides elastic return force to realize the automatic opening and closing of the heat dissipation hole and automatically control ventilation when the display screen is raised and lowered, taking into account both heat dissipation and sealing. The support guide assembly includes a lateral fixed plate and the guide strip. The lateral fixed plate is fixedly installed on the side wall of the vertical strip. The lateral moving column is slidably installed on the lateral fixed plate. The closing plate is fixedly connected to one end of the lateral moving column, and the closing plate is elastically connected to the lateral fixed plate through the return spring.

[0013] Preferably, in order to enable the first arc-shaped sliding surface and the second arc-shaped sliding surface to cooperate and guide the sealing plate to open and close smoothly, the guide roller rotates in the hollow groove to reduce friction, realize the sealing plate to slide smoothly with low resistance, and ensure that the heat dissipation hole switches flexibly and is positioned accurately. The guide strip is fixed on the inner wall of the box and the guide strip is vertically aligned with the sealing plate. The bottom of the guide strip is provided with a first arc-shaped sliding surface and the top of the sealing plate is provided with a second arc-shaped sliding surface. The first arc-shaped sliding surface and the second arc-shaped sliding surface are vertically aligned. A hollow groove is opened on the guide strip, and a guide roller is rotatably installed on the inner wall of the hollow groove. The guide roller is evenly distributed along the vertical direction of the guide strip.

[0014] Preferably, in order to ensure that the base plates are circumferentially distributed within the housing, providing a stable mounting base for the components, making reasonable use of the space inside the housing, facilitating the integrated installation and maintenance of the drive motor and control components, and improving the overall integrity and ease of maintenance of the device, multiple base plates are fixedly installed on the inner wall of the bottom end of the housing. The multiple base plates are evenly distributed circumferentially for mounting the components.

[0015] Preferably, in order to ensure that the encapsulation plate seals the top of the housing and allows the display screen to move up and down through the clearance hole, the glass frame is quickly attached and detached from the encapsulation plate via the magnetic block.

[0016] The beneficial effects of this invention are: the pin connection component can selectively connect to display screens, flexibly switching between single-screen or multi-screen display modes. The vertical bar slides in conjunction with the vertical frame, providing precise guidance and limiting, ensuring smooth lifting and accurate positioning. At the same time, the closed structure is linked with the vertical bar; when the display screen extends, the heat dissipation holes automatically open for ventilation and heat dissipation, and when it retracts, the closed plate automatically covers the heat dissipation holes to achieve sealing and dust prevention, thus meeting both heat dissipation and protection requirements without additional operation.

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1-9As shown, this embodiment provides an interactive multimedia integrated display device for exhibition halls, including a housing 1, a drive structure, multiple display screens 6, a vertical frame 7, and a closed structure. The housing 1 has a pentagonal cross-section, and heat dissipation holes 2 penetrating the interior of the housing 1 are provided on the outer wall of the housing 1. These heat dissipation holes 2 can quickly dissipate the heat generated by the components inside the housing 1 during operation, effectively reducing the temperature inside the housing and preventing overheating damage to the components due to heat accumulation. This ensures the stability and service life of the display screens 6 and drive structure during long-term operation. The drive structure is installed on the inner wall at the bottom of the housing 1. The drive structure includes multiple connecting plates 3 and an adjustment component 4 for controlling the lifting and lowering of the connecting plates 3. The multiple connecting plates 3 are evenly distributed in a circle on the adjustment component 4. The adjustment component 4 controls the synchronous lifting and lowering of the multiple evenly distributed connecting plates 3 to achieve uniform adjustment of the height of the display screens 6. The display screen 6 can slide along the vertical frame 7 and extend out of the box 1 for display. When retracted, it is put back into the box 1, which facilitates flexible adjustment of the display height in different exhibition hall scenarios. At the same time, the circumferential distribution ensures that the lifting and lowering of multiple screens is stable and consistent, improving the display effect and the stability of the device operation. The connecting plate 3 is equipped with a pin connecting component 5, which includes a vertical bar 501. Multiple display screens 6 are located inside the box 1 and correspond one-to-one with the inner wall of the box 1. The vertical frame 7 is fixed on the inner wall at the bottom of the box 1. The display screen 6 is located on one side of the vertical frame 7 and is slidably connected to the vertical frame 7 through the vertical bar 501. The vertical bar 501 guides the sliding on the vertical frame 7, so that the display screen 6 can be raised and lowered smoothly and extend or retract into the box 1, realizing the flexible unfolding and storage of the screen. The vertical bar 501 provides precise guidance and limiting, preventing the display screen 6 from swaying or shifting, ensuring smooth lifting and accurate positioning, balancing display effect and operational stability. Furthermore, with the help of the pin connecting component 5, the display screen 6 can be selectively connected to the connecting plate 3 for individual display or selection of different display quantities. The enclosed structure is connected to the vertical bar 501 and includes a sealing plate 8 and a support guide component 9 that controls the position of the sealing plate 8. The sealing plate 8 corresponds to the heat dissipation hole 2. When the display screen 6 is lifted and lowered along the vertical frame 7 with the vertical bar 501, the support guide component 9 synchronously drives the sealing plate 8 to move, ensuring precise alignment between the sealing plate 8 and the heat dissipation hole 2. When the display screen 6 retracts into the housing 1, the sealing plate 8 covers the heat dissipation hole 2, providing a sealing and dustproof function; when the display screen 6 extends out for display, the sealing plate 8 moves upward to the side of the heat dissipation hole 2, allowing the heat dissipation hole 2 to be exposed, ensuring ventilation and heat dissipation within the housing 1. The heat dissipation hole 2 automatically opens and closes as the display screen 6 rises and falls, taking into account both sealing protection and heat dissipation requirements.

[0029] As a technical optimization solution of the present invention, specifically as follows: Figure 4As shown, the adjustment component 4 includes a threaded rod 401 and a threaded block 402. The threaded rod 401 is rotatably mounted on the inner wall of the bottom end of the housing 1 via a rotary joint 403. The threaded block 402 is threadedly fitted onto the threaded rod 401. An adjustment block 404 is fixedly mounted on the top of the threaded block 402 and fitted onto the threaded rod 401. The connecting plate 3 is fixedly connected to the adjustment block 404. By rotating the threaded rod 401, the threaded block 402 spirals up and down along the threaded rod 401, driving the adjustment block 404 and the connecting plate 3 to move synchronously, achieving uniform lifting and lowering of multiple evenly distributed connecting plates 3, thereby adjusting the height of the display screen 6. The threaded connection has self-locking properties, ensuring smooth lifting and precise positioning, preventing the connecting plates 3 from sliding down due to vibration, ensuring consistent height of multiple screens, and providing easy operation, thus guaranteeing the long-term stability and display effect of the device. The adjustment assembly 4 also includes a support frame 405, which is fixed to the inner wall of the bottom of the housing 1. One end of a threaded rod 401 is rotatably inserted into the top of the support frame 405. A drive motor 406 is fixedly installed on the top of the support frame 405, and one end of the threaded rod 401 is fixedly connected to the output shaft of the drive motor 406. A limit slide rod 407 is fixedly installed on the inner wall of the top of the support frame 405, and one end of a threaded block 402 is slidably fitted onto the limit slide rod 407. In use, the drive motor 406 starts and drives the threaded rod 401 to rotate. Under the guidance of the limit slide rod 407, the threaded block 402 rises and falls smoothly along the threaded rod 401, preventing the threaded block 402 from rotating with the rod and ensuring precise and linear lifting motion. The support frame 405 provides stable support for the threaded rod 401 and the drive motor 406, and the limit slide rod 407 constrains the movement trajectory of the threaded block 402, preventing deviation and shaking, making the synchronous lifting of multiple connecting plates 3 more stable and reliable, improving adjustment accuracy and device operation stability.

[0030] As a technical optimization solution of the present invention, specifically as follows: Figure 6 , Figure 7 and Figure 8As shown, the pin connection assembly 5 also includes a positioning seat 502, an insert block 503, and a pin seat 504. The positioning seat 502 is fixed to the top of the connecting plate 3. An adjusting cylinder 505 is fixedly installed on the positioning seat 502. A pin block 506 is fixedly connected to the telescopic end of the adjusting cylinder 505. The pin block 506 corresponds to the pin hole opened on the side wall of the pin seat 504. The telescopic movement of the adjusting cylinder 505 drives the pin block 506 to insert or disengage from the pin hole on the side wall of the pin seat 504, realizing the quick connection or separation of the display screen 6 and the connecting plate 3, realizing the quick assembly and disassembly of the display screen 6, taking into account both connection reliability and switching flexibility, and facilitating the flexible selection of single-screen or multi-screen display. The pin seat 504 is fixed to the side wall of the vertical strip 501. A vertical slot is opened on the vertical frame 7. The vertical strip 501 is slidably connected to the vertical slot through the insert block 503. The vertical bar 501 is slidably connected to the vertical slot of the vertical frame 7 via the mounting block 503, allowing the display screen 6 to rise and fall smoothly along the vertical frame 7, extending or retracting into the housing 1. The pin seat 504 is fixed to the side wall of the vertical bar 501, providing a stable base for the pin connection. The vertical slot provides precise guidance and limiting, preventing the display screen 6 from swaying or shifting, ensuring smooth lifting and accurate positioning, and balancing operational stability and display effect.

[0031] As a technical optimization solution of the present invention, specifically as follows: Figure 7 and Figure 9 As shown, the supporting guide assembly 9 includes a lateral fixing plate 901 and a guide bar 902. The lateral fixing plate 901 is fixedly installed on the side wall of the vertical bar 501. A transverse moving column 903 is slidably installed on the lateral fixing plate 901. The closing plate 8 is fixedly connected to one end of the transverse moving column 903, and the closing plate 8 is elastically connected to the lateral fixing plate 901 through a return spring 904. The vertical bar 501 moves up and down, causing the lateral fixing plate 901 and the transverse moving column 903 to move synchronously, driving the closing plate 8 to slide open and close the heat dissipation hole 2. The return spring 904 provides elastic return force. When the display screen 6 retracts, the spring pulls the closing plate 8 to automatically cover the heat dissipation hole 2 for dust prevention and sealing; when it extends, the closing plate 8 automatically opens the heat dissipation hole 2 to ensure ventilation. The mechanical linkage realizes the automatic opening and closing of the heat dissipation hole 2, taking into account both protection and heat dissipation. Guide strip 902 is fixed to the inner wall of housing 1, and vertically corresponds to the sealing plate 8. The bottom of guide strip 902 has a first arc-shaped sliding surface, and the top of sealing plate 8 has a second arc-shaped sliding surface. The first and second arc-shaped sliding surfaces are vertically aligned. A hollow groove is formed on guide strip 902, and guide rollers 905 are rotatably mounted on the inner wall of the hollow groove. Guide rollers 905 are evenly distributed along the vertical direction of guide strip 902. During use, as sealing plate 8 rises and falls, its top second arc-shaped sliding surface slides along the bottom first arc-shaped sliding surface of guide strip 902, transforming line contact into surface contact to prevent sealing plate 8 from jamming or shifting. Guide rollers 905 rotate within the hollow groove, converting sliding friction into rolling friction, significantly reducing running resistance, ensuring smooth opening and closing of sealing plate 8, and improving the accuracy and reliability of the automatic opening and closing of heat dissipation holes 2.

[0032] As a technical optimization solution of the present invention, specifically as follows: Figure 1 As shown, multiple base plates 10 are fixedly installed on the inner wall of the bottom of the housing 1. These base plates 10 are evenly distributed circumferentially for mounting components. A sealing plate 11 is fixedly installed on the top of the housing 1. The sealing plate 11 has clearance holes that vertically correspond to the display screen 6. A glass frame 12 is located on the top of the sealing plate 11 and is fixedly connected to it via a magnetic block 13. In use, each component is mounted on the evenly distributed base plates 10, a reasonable layout, and the heat dissipation holes 2 effectively cool it. When the display screen 6 extends, it passes through the clearance holes on the sealing plate 11 without interference. After display, the glass frame 12 is fixed to the top of the sealing plate 11, sealing the housing 1. The glass frame 12 protects the interior during normal use, and the magnetic connection facilitates easy assembly and disassembly, improving overall stability.

[0033] Working principle: In use, firstly, according to the display requirements of a single screen or multiple screens, adjust the cylinder 505 to extend and retract the drive pin 506 to insert or disengage from the pin hole on the side wall of the pin seat 504, quickly connecting or separating the selected display screen 6 from the connecting plate 3. Start the drive motor 406 to drive the threaded rod 401 to rotate. Under the guidance of the limit slide rod 407, the threaded block 402 smoothly rises and falls along the threaded rod 401, driving the adjusting block 404 and the evenly distributed connecting plate 3 to rise and fall synchronously, adjusting the display screen 6 to the required height. During display, the display screen 6 slides smoothly out of the housing 1 along the vertical slot of the vertical frame 7, driven by the vertical bar 501. The vertical bar 501 drives the lateral fixing plate 901 and the transverse moving column 903 to move upward simultaneously. The sealing plate 8 moves upward automatically under the coordinated guidance of the return spring 904, the arc-shaped sliding surface of the guide bar 902, and the guide roller 905, exposing the heat dissipation holes 2 for ventilation and heat dissipation. At the same time, the second arc-shaped sliding surface at the top of the sealing plate 8 slides along the first arc-shaped sliding surface at the bottom of the guide bar 902, and the guide roller 905 converts sliding friction into rolling friction, ensuring smooth and precise opening and closing of the sealing plate 8. When the display screen 6 retracts, the vertical bar 501 drives the sealing plate 8 to move downward, and the return spring 904 pulls the sealing plate 8 to automatically cover the heat dissipation holes 2, achieving a sealing and dustproof function. The components are installed on the evenly distributed circumferential base plate 10, and the heat dissipation holes 2 effectively cool them. When stored, the glass frame 12 is fixed by the magnetic block 13 to achieve the sealing of the housing 1.
