Description

Technical Field

[0001] This invention relates to the field of VR display device technology, and in particular to a smart cultural tourism VR display device and its usage method. Background Technology

[0002] Smart tourism refers to the use of next-generation information technologies such as cloud computing, big data, and the Internet of Things to deeply integrate and develop cultural and tourism information resources, thereby achieving the digital and intelligent upgrading of the cultural and tourism industry, improving the quality of cultural and tourism services, management level, and marketing effectiveness, and providing tourists with a more convenient, personalized, and immersive cultural and tourism experience. VR glasses can present historical and cultural scenes and natural landscapes to tourists in a realistic virtual form through high-precision 3D modeling and rendering technology.

[0003] The above-mentioned and existing technologies have the following drawbacks: When using VR glasses, since the distance between the two lenses of VR glasses is fixed, when a passenger with asymmetrical eyes uses VR glasses, it is easy for one eye to see the picture clearly while the other eye sees a blurry picture, which cannot form a clear and uniform visual effect and reduces the practicality of VR glasses.

[0004] Therefore, a VR display device for smart cultural tourism and its usage method are proposed. Summary of the Invention

[0005] The purpose of this invention is to address the problem that when travelers with asymmetrical eyes use VR glasses, one eye can see the image clearly while the other eye sees a blurry image. This invention proposes a smart VR display device for cultural tourism and its usage method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a VR display device for smart cultural tourism and its usage method, comprising a display shell and two lenses, wherein the display shell has a built-in cloud service module, a gyroscope sensor module and an accelerometer sensor module, a strap is fixedly mounted on the outer wall of the display shell, and a display screen is fixedly mounted inside the display shell, and further comprising: An adjustment structure is provided on the inner wall of the display shell for adjusting the lens spacing. The adjustment structure includes a fixing block fixedly installed on the inner wall of the display shell and an adjustment plate for moving the lens. A protective structure is provided on the outer wall of the display shell to protect the lens. The protective structure includes an elastic rope fixedly installed on the outer wall of the display shell and a protective plate for shielding the lens. A cleaning structure disposed on the surface of the protective plate for cleaning the lens, the cleaning structure including an annular groove formed on the surface of the protective plate and lint for cleaning the lens.

[0007] The aforementioned components achieve the following effects: By setting up an adjustment structure, the position of the lens can be adjusted horizontally and vertically to align the lens with the traveler's eyes, thus preventing a situation where one eye can see the image clearly while the other sees a blurry image, improving the practicality of the VR glasses. By setting up a protective structure, when the VR glasses are not in use, a protective plate will shield the lens, preventing foreign objects from hitting the lens and extending its lifespan. By setting up a cleaning structure, after the protective plate is in place, the lint will press against the lens surface. When the lens is moved, the lint will brush off the dust adhering to the lens surface, and the dust will adhere to the lint, fixing it in place and preventing secondary contamination of the lens by dust. This further ensures that the traveler sees a clear image and improves the traveler's user experience.

[0008] Preferably, a rotating tube is rotatably connected inside the fixed block, a connecting tube is fixedly mounted at one end of the rotating tube, the connecting tube is slidably sleeved on the surface of the adjusting plate, the adjusting plate is fixedly connected to the lens, a second electric push rod is fixedly mounted on the outer wall of the connecting tube, the output end of the second electric push rod is fixedly connected to the adjusting plate, a servo motor is fixedly mounted on the inner wall of the display shell, a gear is fixedly mounted on the output end of the servo motor, a gear ring is fixedly mounted on the outer circumferential surface of the rotating tube, the gear meshes with the gear ring, a perforated plate is fixedly mounted on the inner wall of the display shell, and a sealing ring abutting against the surface of the perforated plate is fixedly mounted on the surface of the lens.

[0009] The effect achieved by the above components is as follows: When the second electric actuator is activated, its output end drives the adjustment plate to slide along the inner wall of the connecting tube. The sliding of the adjustment plate drives the lens to slide, thereby adjusting the position of the lens in the horizontal direction. Then, the servo motor is activated, and the rotation of the servo motor's output end drives the gear to rotate. The gear drives the gear ring to rotate, and the gear ring drives the rotating tube to rotate along the fixed block. The rotating tube drives the connecting tube to move, and the adjustment plate follows the movement of the connecting tube to adjust the vertical position of the lens. By adjusting the position of the lens in the horizontal and vertical directions, the lens can be aligned with the traveler's eyes, thereby avoiding the situation where one eye can see the image clearly while the other eye sees a blurry image, thus improving the practicality of the VR glasses.

[0010] Preferably, a support is fixedly assembled on the inner wall of the display shell, a first electric actuator is fixedly assembled inside the support, and an arc-shaped plate is fixedly assembled at the output end of the first electric actuator.

[0011] The effect achieved by the above components is as follows: after the lens position is adjusted, the output end of the first electric push rod is extended, and the arc plate will abut against the tooth surface of the gear ring. The arc plate can limit the position of the gear ring after the servo motor is turned off, thereby keeping the lens position stable and preventing the lens from shaking and shifting.

[0012] Preferably, a guide rod that penetrates the support is fixedly mounted on the surface of the arc-shaped plate.

[0013] The effect achieved by the above components is that the movement of the arc plate will cause the guide rod to slide along the support, and the guide rod will limit the movement path of the arc plate, so that the arc plate is aligned with the toothed ring.

[0015] The effect achieved by the above components is that during the movement of the adjustment plate, the protrusion will move along the relief hole. The relief hole and the protrusion cooperate to limit the stroke of the second electric push rod and prevent the adjustment plate from coming out of the connecting tube.

[0016] Preferably, the protective plate is fixedly assembled to one end of the elastic rope, a clamping plate is fixedly assembled on the surface of the perforated plate, the surface of the clamping plate is provided with an inclined surface, an insert plate is fixedly assembled on the side of the protective plate near the perforated plate, the insert plate is slidably connected to the clamping plate, the insert plate abuts against the surface of the perforated plate, a fixing rod is fixedly assembled on the surface of the insert plate, a sliding plate is slidably fitted on the surface of the fixing rod, and the sliding plate is slidably connected to the clamping plate.

[0017] The effect achieved by the above components is as follows: when VR glasses are not in use, the protective plate is moved so that the insert plate is inserted into the card plate. The card plate restricts the movement path of the insert plate. The fixing rod moves with the insert plate and drives the slide plate to move. When the slide plate touches the surface of the card plate, the card plate restricts the position of the slide plate, thereby restricting the position of the protective plate. The protective plate will block the lens and prevent foreign objects from hitting the lens, thus extending the lens's service life.

[0018] Preferably, the surface of the fixing rod is fitted with a spring, and the two ends of the spring are fixedly connected to the sliding plate and the insert plate, respectively.

[0019] The effect achieved by the above components is that when the spring is extended, the slide will slide against the surface of the card plate with the help of the spring's elastic force.

[0020] Preferably, the inner wall of the annular groove is provided with a retaining ring, and an mounting plate is fixedly mounted on the surface of the retaining ring, and the fluffy fibers are fixedly mounted on the surface of the mounting plate.

[0021] The effect achieved by the above components is as follows: after the protective plate is placed, the lint will press against the surface of the lens. Then, with the help of the servo motor and the second electric push rod, the position of the lens is moved. The lint will brush off the dust attached to the lens surface, and the dust will adhere to the lint, fixing the dust and preventing the dust from causing secondary pollution to the lens.

[0022] Preferably, a first magnetic sheet is fixedly assembled inside the protective plate, and a second magnetic sheet is fixedly assembled on the side of the mounting plate close to the first magnetic sheet, wherein the magnetic poles of the first magnetic sheet and the second magnetic sheet are opposite in direction on the side close to each other.

[0023] The effect achieved by the above components is that the first and second magnetic sheets attract each other and restrict the position of the mounting plate, thereby preventing the retaining ring from coming out of the annular groove.

[0024] The method for using VR display devices for smart cultural tourism includes the following steps: S1. Obtain the required tourism display materials through the cloud service module; S2. Secure the VR glasses using the straps; S3. Use the second electric push rod and servo motor to adjust the position of the lens in the horizontal and vertical directions so that the lens is aimed at the passenger's eyes. S4. Play video using the display screen; S5. When no passengers are using VR glasses, use the card plate, insert plate and slide plate to restrict the position of the protective plate and use the protective plate to protect the lens; S6. When maintaining VR glasses, move the mounting plate to engage the retaining ring with the annular groove, and move the lens to clean it using the lint.

[0025] Compared with the prior art, the advantages and positive effects of the present invention are as follows: In this invention, by setting an adjustment structure, the position of the lens can be adjusted in both the horizontal and vertical directions to align the lens with the traveler's eyes, thereby avoiding the situation where one eye can see the image clearly while the other eye sees a blurry image, thus improving the practicality of VR glasses.

[0026] In this invention, after the lens position is adjusted, the output end of the first electric push rod is extended, and the arc plate will abut against the tooth surface of the gear ring. The arc plate can limit the position of the gear ring after the servo motor is turned off, thereby keeping the lens position stable and preventing the lens from shaking and shifting.

[0027] In this invention, by setting up a protective structure, when the VR glasses are not in use, the protective plate will block the lens, preventing foreign objects from hitting the lens and thus extending the lens's service life.

[0028] In this invention, by setting up a cleaning structure, after the protective plate is placed, the lint will press against the surface of the lens. When the position of the lens is moved, the lint will brush off the dust attached to the lens surface, and the dust will adhere to the lint, fixing the dust and preventing the dust from causing secondary pollution to the lens. This further ensures that tourists can see a clear picture and improves the user experience. Attached Figure Description

This prevents one eye from seeing a clear image while the other sees a blurry one, improving the practicality of the VR glasses. A protective structure 21 shields lens 4 when not in use, preventing foreign objects from hitting it and extending its lifespan. The cleaning structure allows the lint 30 to press against the lens 4 surface after the protective plate 21 is in place. When the lens 4 is moved, the lint 30 brushes off dust adhering to its surface, trapping the dust within the lint 30 and preventing secondary contamination. This further ensures a clear image for the traveler and improves the user experience.

[0034] The aforementioned components achieve the following effects: By setting an adjustment structure, the position of the lens 4 can be adjusted horizontally and vertically to align the lens 4 with the traveler's eyes, thus preventing a situation where one eye can see the image clearly while the other sees a blurry image, improving the practicality of the VR glasses. By setting a protective structure, when the VR glasses are not in use, the protective plate 21 will shield the lens 4, preventing foreign objects from hitting the lens 4, thereby extending the lifespan of the lens 4. By setting a cleaning structure, after the protective plate 21 is placed, the lint 30 will press against the surface of the lens 4. When the position of the lens 4 is moved, the lint 30 will brush off the dust adhering to the surface of the lens 4, and the dust will adhere to the lint 30, fixing the dust and preventing secondary contamination of the lens 4 by dust, thereby further ensuring that the traveler sees a clear image and improving the traveler's user experience.

[0035] A rotating tube 6 is rotatably connected inside the fixed block 5. A connecting tube 7 is fixedly mounted at one end of the rotating tube 6. The connecting tube 7 is slidably sleeved on the surface of the adjusting plate 8. The adjusting plate 8 is fixedly connected to the lens 4. A second electric push rod 33 is fixedly mounted on the outer wall of the connecting tube 7. The output end of the second electric push rod 33 is fixedly connected to the adjusting plate 8. A servo motor 9 is fixedly mounted on the inner wall of the display shell 1. A gear 10 is fixedly mounted on the output end of the servo motor 9. A gear ring 11 is fixedly mounted on the outer circumference of the rotating tube 6. The gear 10 meshes with the gear ring 11. A perforated plate 12 is fixedly mounted on the inner wall of the display shell 1. A sealing ring 13 is fixedly mounted on the surface of the lens 4 and abuts against the surface of the perforated plate 12. When the second electric push rod 33 is turned on, the second electric push rod 33... The output end of the device drives the adjustment plate 8 to slide along the inner wall of the connecting tube 7. The sliding of the adjustment plate 8 drives the lens 4 to slide, thereby adjusting the position of the lens 4 in the horizontal direction. Then, the servo motor 9 is turned on. The rotation of the output end of the servo motor 9 drives the gear 10 to rotate. The gear 10 drives the gear ring 11 to rotate. The gear ring 11 drives the rotating tube 6 to rotate along the fixed block 5. The rotating tube 6 drives the connecting tube 7 to move. The adjustment plate 8 follows the movement of the connecting tube 7 to adjust the vertical position of the lens 4. By adjusting the position of the lens 4 in the horizontal and vertical directions, the lens 4 can be aligned with the traveler's eyes, thereby avoiding the situation where one eye can see the picture clearly while the other eye is blurry, thus improving the practicality of the VR glasses.

[0036] A support 16 is fixedly mounted on the inner wall of the display housing 1. A first electric actuator 17 is fixedly mounted inside the support 16. An arc-shaped plate 18 is fixedly mounted on the output end of the first electric actuator 17. After the position of the lens 4 is adjusted, the output end of the first electric actuator 17 is extended, and the arc-shaped plate 18 will abut against the tooth surface of the gear ring 11. The arc-shaped plate 18 can limit the position of the gear ring 11 after the servo motor 9 is turned off, thereby keeping the position of the lens 4 stable and preventing the lens 4 from shaking and shifting. A guide that penetrates the support 16 is fixedly mounted on the surface of the arc-shaped plate 18. The movement of the guide rod 19 and the arc plate 18 will cause the guide rod 19 to slide along the support 16. The guide rod 19 can limit the movement path of the arc plate 18 and make the arc plate 18 aligned with the toothed ring 11. The surface of the connecting pipe 7 is provided with a relief hole 14. The surface of the connecting plate is fixedly fitted with a protrusion 15. The protrusion 15 passes through the relief hole 14. During the movement of the adjusting plate 8, the protrusion 15 will move along the relief hole 14. The relief hole 14 and the protrusion 15 cooperate to limit the stroke of the second electric push rod 33 and prevent the adjusting plate 8 from coming out of the connecting pipe 7.

[0037] The protective plate 21 is fixedly mounted on one end of the elastic rope 20. A clamping plate 22 is fixedly mounted on the surface of the perforated plate 12. The surface of the clamping plate 22 has an inclined surface. An insert plate 23 is fixedly mounted on the side of the protective plate 21 near the perforated plate 12. The insert plate 23 is slidably connected to the clamping plate 22. The insert plate 23 abuts against the surface of the perforated plate 12. A fixing rod 24 is fixedly mounted on the surface of the insert plate 23. A sliding plate 25 is slidably fitted on the surface of the fixing rod 24. The sliding plate 25 is slidably connected to the clamping plate 22. When the VR glasses are not in use, moving the protective plate 21 causes the insert plate 23 to insert into the clamping plate 22, and the clamping plate 22 restricts the movement of the insert plate 23. The moving path allows the fixed rod 24 to move along with the insert plate 23, which in turn moves the slide plate 25. When the slide plate 25 abuts against the surface of the clamping plate 22, the clamping plate 22 restricts the position of the slide plate 25, thereby restricting the position of the protective plate 21. The protective plate 21 will shield the lens 4, preventing foreign objects from hitting the lens 4 and thus extending the service life of the lens 4. The surface of the fixed rod 24 is fitted with a spring 26, and the two ends of the spring 26 are fixedly connected to the slide plate 25 and the insert plate 23, respectively. When the spring 26 extends, the slide plate 25 will slide against the surface of the clamping plate 22 with the help of the elastic force of the spring 26.

[0038] A retaining ring 28 is provided on the inner wall of the annular groove 27. A mounting plate 29 is fixedly mounted on the surface of the retaining ring 28. A filament 30 is fixedly mounted on the surface of the mounting plate 29. After the protective plate 21 is placed, the filament 30 will press against the surface of the lens 4. Then, the position of the lens 4 is moved by the servo motor 9 and the second electric push rod 33. The filament 30 will brush off the dust attached to the surface of the lens 4, and the dust will adhere to the filament 30, fixing the dust and preventing the dust from causing secondary pollution to the lens 4. A first magnetic sheet 31 is fixedly mounted inside the protective plate 21. A second magnetic sheet 32 ​​is fixedly mounted on the side of the mounting plate 29 close to the first magnetic sheet 31. The magnetic poles of the first magnetic sheet 31 and the second magnetic sheet 32 ​​are opposite in direction on the side close to each other. The first magnetic sheet 31 and the second magnetic sheet 32 ​​will attract each other and restrict the position of the mounting plate 29, thereby preventing the retaining ring 28 from coming out of the annular groove 27.

[0039] The method for using VR display devices for smart cultural tourism includes the following steps: S1. Obtain the required tourism display materials through the cloud service module; S2. Secure the VR glasses using strap 2; S3. Using the second electric push rod 33 and the servo motor 9, adjust the position of the lens 4 in the horizontal and vertical directions so that the lens 4 is aimed at the passenger's eyes. S4. Play video using display screen 34; S5. When no passengers are using VR glasses, the position of the protective plate 21 is restricted by the cooperation of the card plate 22, the insertion plate 23 and the sliding plate 25, and the protective plate 21 is used to protect the lens 4. S6. When maintaining the VR glasses, the movable mounting plate 29 engages the retaining ring 28 with the annular groove 27, and the lens 4 is moved to clean the lens 4 using the lint 30.

[0040] Its overall working principle is as follows: The cloud service module can obtain necessary tourism information from the cloud server; the gyroscope sensor module measures the angular velocity of the VR glasses, sensing their rotation in real time and providing head rotation information to the system. This allows the virtual scene to update its display in real time based on the user's head movement; the accelerometer detects acceleration changes in three axes, working in conjunction with the gyroscope sensor module to more accurately calculate the head's trajectory and posture, improving tracking accuracy and making the VR glasses more intelligent; and the display screen 34 can play images and content set up in the scenic area. When the eyes are not in close proximity... When passengers are positioned symmetrically, the display shell 1 is fixed to the passenger's head using strap 2. The flexible ring 3 can fit against the passenger's face to block light. Then, the distance between the lenses 4 is adjusted according to the passenger's interpupillary distance. During this process, when the second electric actuator 33 is activated, the output end of the second electric actuator 33 will drive the adjustment plate 8 to slide along the inner wall of the connecting tube 7. The sliding of the adjustment plate 8 will drive the lens 4 to slide, thereby adjusting the position of the lens 4 in the horizontal direction. During the movement of the adjustment plate 8, the protrusion 15 will move along the clearance hole 14. The clearance hole 14 and the protrusion 15 cooperate to limit the stroke of the second electric actuator 33 and prevent the adjustment plate 8 from detaching from the connecting tube 7. Afterwards, servo motor 9 is activated. The rotation of the output end of servo motor 9 drives gear 10 to rotate, gear 10 drives gear ring 11 to rotate, gear ring 11 drives rotating tube 6 to rotate within fixed block 5, rotating tube 6 drives connecting tube 7 to move, and adjusting plate 8 moves with connecting tube 7 to adjust the vertical position of lens 4. By adjusting the position of lens 4 in both the horizontal and vertical directions, lens 4 can be aligned with the traveler's eyes, thus avoiding the situation where one eye can see the image clearly while the other eye sees a blurry image, improving the practicality of VR glasses. The movement of lens 4 causes sealing ring 13 to slide along the surface of perforated plate 12. The combination of 12 and sealing ring 13 ensures the sealing around lens 4, preventing light transmission and ensuring normal adjustment of lens 4. After adjusting the position of lens 4, the output end of the first electric push rod 17 is extended, and the arc plate 18 abuts against the tooth surface of the toothed ring 11. The arc plate 18 can limit the position of the toothed ring 11 after the servo motor 9 is turned off, thereby keeping the position of lens 4 stable and preventing lens 4 from shaking and shifting. The movement of the arc plate 18 will drive the guide rod 19 to slide along the support 16. The guide rod 19 achieves the function of limiting the movement path of the arc plate 18 and aligning the arc plate 18 with the toothed ring 11.

[0041] When the VR glasses are not in use, the movable protective plate 21 causes the insert plate 23 to be inserted into the clamping plate 22. The clamping plate 22 restricts the movement path of the insert plate 23. The fixing rod 24 moves with the insert plate 23, which in turn moves the sliding plate 25. When the sliding plate 25 contacts the inclined surface of the clamping plate 22, the clamping plate 22 will squeeze the sliding plate 25. The sliding plate 25 will slide along the surface of the fixing rod 24 and compress the spring 26. When the insert plate 23 abuts against the surface of the perforated plate 12, the sliding plate 25 will disengage from the inclined surface of the clamping plate 22. The spring 26 will start to extend, and the sliding plate 25 will slide against the surface of the clamping plate 22 with the help of the elastic force of the spring 26. The clamping plate 22 restricts the position of the sliding plate 25, thereby restricting the position of the protective plate 21. The protective plate 21 will shield the lens 4 to prevent foreign objects from hitting the lens 4, thereby extending the service life of the lens 4.

[0042] When cleaning the lens 4 is required, before using the protective plate 21, the movable mounting plate 29 engages the retaining ring 28 with the annular groove 27. At this time, the first magnetic piece 31 and the second magnetic piece 32 will attract each other and restrict the position of the mounting plate 29, thereby preventing the retaining ring 28 from coming out of the annular groove 27. After the protective plate 21 is placed, the lint 30 will press against the surface of the lens 4. Then, with the help of the servo motor 9 and the second electric push rod 33, the position of the lens 4 is moved. The lint 30 will brush off the dust attached to the surface of the lens 4, and the dust will adhere to the lint 30, fixing the dust and preventing the dust from causing secondary pollution to the lens 4. This further ensures that the viewer can see a clear picture and improves the user experience.
