Description

Technical Field

[0001] This utility model relates to a real-time display device for VR digital interaction in exhibition halls, and particularly to a real-time display device for VR digital interaction in exhibition halls applied in the field of VR interaction. Background Technology

[0002] VR is the culmination of rapid development in scientific fields such as computer hardware and software technology, sensing technology, robotics, artificial intelligence, and behavioral psychology. With the development of VR technology, true virtual reality is realized, making users seem to be in a three-dimensional world with visual, auditory, tactile, and even olfactory sensations. Therefore, VR digital interactive real-time display devices are often used in modern exhibition halls (such as science and technology exhibition halls).

[0003] To address the issue of the inconvenience of quickly assembling and disassembling motion-sensing cameras, a VR-based virtual avatar interactive device on the market has adopted a quick-release structure design and has a certain market share.

[0004] Patent document CN220820622U discloses a VR-based virtual avatar interactive device, including a base with multiple casters fixedly mounted at the bottom, a mounting plate fixedly mounted at the top, multiple bolts fixedly mounted on the outer side of the mounting plate, an outer frame fixedly mounted on the top of the mounting plate, multiple supplementary lights mounted on the outer side of the outer frame, a display screen fixedly mounted on the outer side of the outer frame, and a motion-sensing camera mounted on the outer side of the outer frame, with a groove on the outer side of the motion-sensing camera. In this VR-based virtual avatar interactive device, pulling a lever causes a spring to retract, allowing the mounting block to engage with the groove, facilitating quick installation of the motion-sensing camera and simplifying future maintenance and replacement. The design of two supplementary lights allows the motion-sensing camera to capture user movements in low-light conditions, preventing interference with normal use and improving the overall practicality of the device.

[0005] Existing VR digital interactive real-time display devices in exhibition halls are usually exposed to the air for a long time after installation, which makes the surface of the display screen prone to dust (mostly floating dust), affecting the display effect. Most existing solutions involve manual wiping and cleaning during non-use periods. However, on the one hand, the cleaning effect of wiping is not stable (there may be oversights and omissions), and on the other hand, wiping and cleaning increases the workload of staff and cannot be done when the equipment is in use, which has certain limitations. Utility Model Content

[0006] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is how to design an exhibition hall VR digital interactive real-time display device that can effectively clean attached dust without hindering the use of the equipment.

[0007] To solve the above problems, this utility model provides a VR digital interactive real-time display device for exhibition halls, including a display device with a display screen on the front, an air inlet at the bottom of the display device, an air outlet at the top of the display device, and a heat dissipation structure inside the display device to exhaust the air inside the display device from the air outlet.

[0008] The air intake is located on the front side of the display screen, and a dust cover is fixed to the opening of the air intake.

[0009] A door-shaped diffuser is fixed to the upper periphery of the display device and is adapted to the top and sides of the display device. The door-shaped diffuser is connected to the air outlet. An air curtain plate is fixed and connected to the front end of the door-shaped diffuser. An air inlet connected to the door-shaped diffuser is opened on the side of the air curtain plate that is fixed to the door-shaped diffuser. An air outlet is opened at the lower end of the air curtain plate. The air outlet covers the surface of the display screen.

[0010] A ring pipe section is formed at the upper corner of the gate-shaped diversion hood. An internal valve body for controlling the opening and closing of the ring pipe section is installed at the opening of the ring pipe section. Diversion holes are also opened on the front side of the gate-shaped diversion hood located on both sides of the display device. Dustproof nets are fixed inside the diversion holes.

[0011] In the VR digital interactive real-time display device in the exhibition hall, the hot air exhausted from the display device is guided to form an air curtain in front of the display screen. On the one hand, it can clean the surface dust of the display screen, and on the other hand, it can isolate external dust from the display screen, making it difficult to adhere to the display screen, thus maintaining the display screen with better performance. It not only achieves the effect of automatically cleaning surface dust, but also does not hinder the use of the device while cleaning.

[0012] In addition, it can also use hot air drawn from inside the display device to create hot air to blow on the user, so that the user can have a more comfortable user experience when using it in cold environments.

[0013] As a further improvement of this application, multiple air outlets are provided, and the multiple air outlets are arranged at equal intervals along the bottom of the air curtain panel from the side closer to the display screen to the side farther away from the display screen.

[0014] As a further improvement of this application, the air outlet includes a pressure-boosting flare and a straight outlet. The pressure-boosting flare is a flare with an upper opening width greater than the lower opening width. The upper end of the straight outlet is connected to the lower end of the pressure-boosting flare, and the straight outlet is a through-hole with a constant width.

[0015] As a further improvement of this application, the straight outlets of the multiple air outlets have different orientations. The air outlets closer to the display screen have their straight outlets tilted towards the display screen, the air outlets farther from the display screen have their straight outlets tilted towards the side farther from the display screen, and the air outlets in the middle have their straight outlets extending vertically downwards.

[0016] As another improvement of this application, a heat-conducting block and a color-changing strip are fixedly embedded on the side of the air curtain panel away from the air inlet. One side of the heat-conducting block extends into the air curtain panel, one side of the color-changing strip is fixed to the side of the heat-conducting block, and the other side of the color-changing strip is exposed on the outside of the side of the air curtain panel away from the display screen. The color-changing strip changes color with the temperature.

[0017] As a further improvement to this application, the built-in valve body includes a gate and a miniature electric push rod. One end of the gate is rotatably connected to the inner wall of the gate-shaped diversion hood, and the other end of the gate is pressed against the opening side wall of the ring pipe section to form a seal. A sealing strip is fixed on the inner side of the gate-shaped diversion hood that is rotatably connected to the gate. The sealing strip is pressed against the upper surface of the gate to form a seal.

[0018] One end of the miniature electric push rod is rotatably connected to the inner wall of the gate-shaped diverter, and the piston rod end of the miniature electric push rod is rotatably connected to the bottom of the gate plate away from the ring pipe section.

[0019] As a further improvement to this application, a miniature cooler is fixed inside the ring pipe section. The miniature cooler is electrically connected to the controller inside the display device, and the controller inside the display device is also electrically connected to the gate.

[0020] As another improvement of this application, the dust cover includes a support shell and a filter cloth. The support shell is a triangular frame. The right-angled sides of the support shell are fixed to the side wall and the top of the air inlet, respectively. The filter cloth is fixedly embedded in the support shell and is inclined towards the side away from the display screen.

[0021] In summary, by guiding the hot air exhausted from the display device to the air curtain plate through the gate-shaped diverter, and blowing the airflow downward through the air outlet below the air curtain plate, the airflow forms an air curtain on one side of the display screen surface. This not only cleans the surface dust of the display screen, but also isolates external dust from adhering to the display screen, thus maintaining the display screen's optimal performance. It not only achieves the effect of automatically cleaning surface dust, but also does not hinder the use of the device during the cleaning process.

[0022] In addition, when the built-in valve at the opening of the ring pipe section is opened, the airflow inside the gate-shaped diverter can also enter both sides of the gate-shaped diverter through the ring pipe section and be discharged through the diversion hole. It can use the internal hot air to form hot air or use the micro-cooler to form cold air and blow it out to blow on the user, so that the user can have a more comfortable user experience when using it in cold or hot environments, and improve the user comfort of the VR digital interactive real-time display device in the exhibition hall.

Detailed Implementation

[0030] The first embodiment of this application will now be described in detail with reference to the accompanying drawings.

[0031] Implementation method 1:

[0032] Figure 1-5 The present invention discloses a VR digital interactive real-time display device for exhibition hall, including a display device 1 with a display screen 101 on the front, an air inlet 102 at the bottom of the display device 1, an air outlet 103 at the top of the display device 1, and a heat dissipation structure inside the display device 1 for discharging air from the display device 1 through the air outlet 103.

[0033] The air inlet 102 is located on the front side of the display screen 101, and a dust cover 4 is fixed to the opening of the air inlet 102.

[0034] A gate-shaped diversion hood 2, which is adapted to the top and sides of the display device 1, is fixed on the upper periphery of the display device 1. The gate-shaped diversion hood 2 is connected to the air outlet 103. An air curtain plate 3 is fixed and connected to the front end of the gate-shaped diversion hood 2. An air inlet 301, which is connected to the gate-shaped diversion hood 2, is opened on the side of the air curtain plate 3 that is fixed to the gate-shaped diversion hood 2. An air outlet 302 is opened at the lower end of the air curtain plate 3. The air outlet 302 covers the surface of the display screen 101.

[0035] A ring pipe section 201 is formed at the upper corner of the gate-shaped diversion cover 2. An internal valve body for controlling the opening and closing of the ring pipe section 201 is installed at the opening of the ring pipe section 201. A diversion hole 202 is also provided on the front side of the gate-shaped diversion cover 2 located on both sides of the display device 1. A dustproof net 5 is fixed inside the diversion hole 202.

[0036] Based on the above structure, the hot air discharged from the display device 1 is guided to the air curtain plate 3 through the door-shaped diversion cover 2, and the airflow is blown downward through the air outlet 302 below the air curtain plate 3, so that the airflow forms an air curtain on one side of the surface of the display screen 101. On the one hand, it can clean the surface dust of the display screen 101, and on the other hand, it can isolate external dust by the air curtain, making it difficult to adhere to the display screen 101, thereby maintaining the display screen 101 with better performance. It not only achieves the effect of automatically cleaning surface dust, but also does not hinder the use of the device while cleaning.

[0037] In addition, when the built-in valve at the opening of the ring pipe section 201 is opened, the airflow inside the gate-shaped diverter 2 can also enter both sides of the gate-shaped diverter 2 through the ring pipe section 201 and be discharged through the diversion hole 202. The hot air inside is used to form hot air to blow on the user, so that the user can have a more comfortable user experience when using it in a cold environment.

[0038] Furthermore, multiple air outlets 302 are provided, and the multiple air outlets 302 are arranged at equal intervals along the bottom of the air curtain panel 3 from the side closer to the display screen 101 to the side farther away from the display screen 101.

[0039] The air outlet 302 includes a pressurizing flare 3021 and a straight outlet 3022. The pressurizing flare 3021 is a flare with an upper opening width greater than a lower opening width, which can pressurize the passing air and increase the airflow speed. The upper end of the straight outlet 3022 is connected to the lower end of the pressurizing flare 3021, and the straight outlet 3022 is a through-hole with a constant width, so that the pressurized airflow forms a stable air curtain and increases the travel of the air curtain to ensure full coverage of the surface of the display screen 101.

[0040] The straight openings 3022 of the multiple air outlets 302 face different directions. The straight openings 3022 of the air outlets 302 closer to the display screen 101 are tilted towards the side of the display screen 101, the straight openings 3022 of the air outlets 302 farther away from the display screen 101 are tilted towards the side farther away from the display screen 101, and the straight openings 3022 of the air outlets 302 located in the middle extend vertically downward.

[0041] By setting multiple air outlets 302 and designing different air outlet angles, multiple air curtains (at least three) are formed on the front side of the display screen 101. The inner air curtain mainly removes dust from the display screen 101, the outer air curtain is used to isolate external dust, and the middle air curtain is used to isolate the inner and outer air curtains and reinforce them, thereby improving the dust removal effect on the surface of the display screen 101 and also improving the dustproof effect.

[0042] Furthermore, a heat-conducting block 303 and a color-changing strip 9 are fixedly embedded on the side of the air curtain panel 3 away from the air inlet 301. The color-changing strip 9 is made of thermosensitive color-changing material in the prior art or coated with thermosensitive color-changing pigment. One side of the heat-conducting block 303 extends into the air curtain panel 3, and one side of the color-changing strip 9 is fixed to the side of the heat-conducting block 303. The other side of the color-changing strip 9 is exposed on the outside of the side of the air curtain panel 3 away from the display screen 101. The color-changing strip 9 changes color with the temperature, which makes it easy for the staff to observe the temperature of the hot air discharged from the display device 1, so as to intuitively judge whether the display device 1 is at a safe operating temperature and facilitate the staff's inspection work.

[0043] Furthermore, the built-in valve body includes a gate plate 7 and a miniature electric push rod 8. One end of the gate plate 7 is rotatably connected to the inner wall of the gate-shaped diversion hood 2, and the other end of the gate plate 7 is pressed against the opening side wall of the ring pipe section 201 to form a seal. A sealing strip 701 is fixed on the inner side of the gate-shaped diversion hood 2 that is rotatably connected to the gate plate 7. The sealing strip 701 is pressed against the upper surface of the gate plate 7 to form a seal.

[0044] One end of the miniature electric push rod 8 is rotatably connected to the inner wall of the gate-shaped diversion hood 2, and the piston rod end of the miniature electric push rod 8 is rotatably connected to the bottom of the gate plate 7 away from the annular pipe section 201. The opening and closing of the gate plate 7 can be controlled by the opening and closing of the miniature electric push rod 8, thereby controlling the opening and closing of the annular pipe section 201. When the gate plate 7 is open, the airflow can flow through the annular pipe section 201 to the diversion hole 202 and be discharged, thereby achieving the purpose of controlling whether the diversion hole 202 is venting air.

[0045] Furthermore, a miniature cooler 6 is fixed inside the ring section 201. The miniature cooler 6 is electrically connected to the controller inside the display device 1. The controller is a commonly used controller in the prior art and applicable to this embodiment, such as a PLC (Programmable Logic Controller), which can realize the conventional control of the display device 1. The controller inside the display device 1 is also electrically connected to the gate 7.

[0046] With the miniature cooler 6 in place, when the miniature cooler 6 is turned on, the air flowing through the ring pipe section 201 will be cooled by the miniature cooler 6, thus becoming cold air. After the cold air is blown out through the diversion hole 202, it can create a cool surrounding environment, thus providing users with a more comfortable user experience in hot environments.

[0047] Furthermore, the dust cover 4 includes a support shell 401 and a filter cloth 402. The support shell 401 is a triangular frame. The right-angled sides of the support shell 401 are fixed to the side wall and the top of the air inlet 102, respectively. The filter cloth 402 is fixedly embedded in the support shell 401. The filter cloth 402 is inclined to the side away from the display screen 101. The inclined filter cloth 402 can not only intercept dust and keep the air entering the display device 1 clean, but also make it difficult for dust to remain on the filter cloth 402 by the blowing of the air curtain above. This greatly reduces the cleaning frequency of the filter cloth 402 and reduces the workload of the staff.

[0048] It should be further noted that the heat dissipation structure, miniature cooler 6, controller, and miniature electric actuator 8 mentioned in this application are all considered prior art, and their specific structures and working principles will not be described again.

[0049] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
