[0081] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0082] As described in the background section, in order to cover more possible imaging areas when dealing with different display areas, the floating display device in the related art needs to use a large-size floating imaging lens to enable the floating display device to cover more display areas. However, the large-size floating imaging lens makes the floating display device occupy a large volume space and increases the manufacturing cost.

[0083] refer to Figure 1 , Figure 3 , Figure 4 , Figure 9 and Figure 10As shown, according to a first aspect of this application, a floating display structure 30 is provided, which includes a floating imaging mechanism 31 and a second driving mechanism. The floating imaging mechanism 31 includes a floating imaging lens 312 and a first driving mechanism. The floating imaging lens 312 is connected to the first driving mechanism, and the first driving mechanism drives the floating imaging lens 312 to project the image to be displayed onto a target imaging area. The second driving mechanism is connected to the floating imaging mechanism 31 and is configured to drive the floating imaging mechanism 31 to move, thereby adjusting the position of the target imaging area.

[0084] It is understood that the floating display structure 30 provided in this application embodiment is mainly achieved through floating imaging technology. Floating imaging technology is a display technology that uses the principle of light field reconstruction to suspend and present images in the air. Specifically, the floating imaging lens 312 refocuses the diverging light rays into a floating image 38. The floating imaging lens 312 can project the image to be displayed onto a symmetrical position with respect to the floating imaging lens 312 as its symmetrical plane, such as... Figure 12 The diagram shown is a schematic of the levitation imaging lens 312 in this embodiment. Figure 12 In this context, "object point" refers to a light-emitting point or reflected light point on the screen to be displayed, through which light rays are emitted in various directions. During propagation, the light rays pass through the floating imaging lens 312. The floating imaging lens 312 modulates the light rays emitted from the "object point," for example, through refraction or reflection, to change the direction of the light rays. After passing through the floating imaging lens 312, the originally divergent light rays propagate along a new path and finally converge at a position symmetrical to the "object point" with the floating imaging lens 312 as its plane of symmetry, forming the "image point" shown in Figure 12, which is the imaging position corresponding to the screen to be displayed. In practical applications, the light rays emitted from several "object points" on the screen to be displayed all pass through the floating imaging lens 312, forming corresponding "image points" at symmetrical positions. A combination of several "image points" constitutes a floating image 38 that is symmetrical and identical to the screen to be displayed on the predetermined device.

[0085] Specifically, in this embodiment, the floating display structure 30 is connected to the first driving mechanism via the floating imaging lens 312 of the floating imaging mechanism 31. The first driving mechanism can drive the floating imaging lens 312, enabling it to completely display the image to be displayed in the target imaging area, thus adapting to the needs of different target imaging areas. This means that the image to be displayed can be completely displayed in different target imaging areas without increasing the size of the floating imaging lens 312, avoiding the problem of a large floating imaging lens 312 size, reducing the production cost of the floating display structure 30, and making it easier to deploy in specific scenarios, better suited to compact environments. In this embodiment, the position of the target imaging area can be adjusted via the second driving mechanism, such as adjusting the height or angle of the target imaging area relative to the user, to meet different viewing needs of customers, improving the practicality and versatility of the floating display structure 30.

[0086] In some embodiments, the buoyancy imaging mechanism 31 further includes a lens support 311, and the buoyancy imaging lens 312 and the first driving mechanism are both connected to the lens support 311.

[0087] Thus, the lens bracket 311 in this embodiment can serve as a support structure for the floating imaging lens 312, and can guide the movement direction of the floating imaging lens 312 when the first driving mechanism drives it, so as to ensure that the image to be displayed by the predetermined device can be accurately transmitted through the floating imaging lens 312 to the target imaging area.

[0088] For example, refer to Figure 2 As shown, the lens bracket 311 in this embodiment is configured as a rectangular frame structure with a lens avoidance area inside. The floating imaging lens 312 is disposed on the rectangular frame structure. The first driving mechanism drives the floating imaging lens 312 to move on the rectangular frame structure. The lens avoidance area avoids the light from the floating imaging lens 312 passing through the image to be displayed, so that the image to be displayed can be completely projected onto the target display area.

[0089] In some embodiments, the first driving mechanism includes a first sliding component 32 and a first driving component 33. The first sliding component 32 is slidably connected to the lens holder 311 and fixedly connected to the buoyancy imaging lens 312. The first driving component 33 is drivingly connected to the first sliding component 32 to at least drive the first sliding component 32 to slide along a first direction.

[0090] Thus, the first sliding component 32 is driven by the first driving component 33 to slide relative to the lens bracket 311. Since the floating imaging lens 312 is fixedly connected to the first sliding component 32, the floating imaging lens 312 also slides relative to the lens bracket 311 along the first direction (reference). Figure 10 The movement (in the direction indicated by the middle arrow m) and the sliding cooperation between the first sliding component 32 and the lens bracket 311 ensure that the floating imaging lens 312 can move smoothly in the first direction within the plane where the floating imaging lens 312 is located. This ensures that the stability and smoothness of the projected floating image 38 are just right during the movement of the floating imaging lens 312 in the first direction, thereby improving the display effect of the floating image 38.

[0091] In some embodiments, the first sliding component 32 includes a first bracket 321 and a first slider 322. A floating imaging lens 312 is disposed on the first bracket 321, and the first bracket 321 is slidably connected to the lens bracket 311 through the first slider 322.

[0092] refer to Figure 2 As shown, in the embodiment of this application, the first support 321 includes two parallel first support rods 3211 arranged at intervals. The two first support rods 3211 are parallel and spaced apart. A floating imaging lens 312 is disposed between the two first support rods 3211. The two sides of the floating imaging lens 312 are fixedly connected to the corresponding first support rods 3211. The two first support rods 3211 are parallel to the plane where the floating imaging lens 312 is located. Both first support rods 3211 are slidably connected to the lens support 311 via first sliders 322. This allows the floating imaging lens 312 to move relative to the lens support 311, preventing the floating imaging lens 312 from contacting the lens support 311 and rubbing against the support during movement, which could cause wear or even damage to the floating imaging lens 312. (Reference) Figure 2 As shown, the first support rod 3211 has a first slider 322 at both ends. The first slider 322 is slidably mounted on the lens bracket 311, which makes the movement of the floating imaging lens 312 smoother and ensures that the movement trajectory does not deviate.

[0093] In some embodiments, the first drive component 33 includes a first drive motor 331 and a first cable 332. The first cable 332 is connected to the first slider 322. The first drive motor 331 is driven to the first cable 332 to drive the first cable 332 to slide the first slider 322 along a first direction.

[0094] Thus, the first drive assembly 33 uses a first drive motor 331 in conjunction with a first cable 332. The first cable 332 has a certain degree of flexibility, which can buffer the impact force when the first drive motor 331 starts or stops, reduce the vibration of the first slider 322 and the floating imaging lens 312, and make the movement of the floating imaging lens 312 more stable.

[0095] For example, the first drive motor 331 in this application embodiment includes a linear motor. The linear motion of the linear motor drives the first cable 332 to extend and retract, thereby driving the first slider 322 to move. The linear motor drives the first cable 332 directly, which can reduce losses, has a fast response speed, and is more suitable for compact space layout.

[0096] In some embodiments, the second driving mechanism includes a moving component 34 and a rotating component 35. The moving component 34 is drivenly connected to the buoyancy imaging mechanism 31 to drive the buoyancy imaging mechanism 31 to move along a second direction. The rotating component 35 is drivenly connected to the buoyancy imaging mechanism 31 to drive the buoyancy imaging mechanism 31 to rotate relative to the moving component 34.

[0097] Thus, the moving component 34 drives the floating imaging mechanism 31 along the second direction (reference). Figure 10 The movement (in the direction indicated by the middle arrow n) adjusts the relative height between the floating image 38 (after the image to be displayed is transmitted through the floating imaging lens 312) and the user. The rotating component 35 drives the floating imaging mechanism 31 to rotate relative to the moving component 34, which can adjust the angle between the floating image 38 (after the image to be displayed is transmitted through the floating imaging lens 312) and the user. This embodiment combines the moving component 34 and the rotating component 35, so that the floating display structure 30 can adapt to different user viewing needs. For example, when dealing with users of different heights or different sitting postures, users can view the floating image 38 with a clear, comfortable, and complete field of vision. Preferably, in this embodiment, the first direction and the second direction are both perpendicular to the rotation axis of the floating imaging mechanism 31, ensuring that the rotation process of the floating imaging mechanism 31 and the movement process along the first direction and the second direction do not interfere with each other, and ensuring the stability of the adjustment process of the image to be displayed or the floating image 38.

[0098] In some embodiments, the moving component 34 includes a second sliding component 341 and a second driving component 342. The second sliding component 341 is slidably disposed on a predetermined structure and fixedly connected to the buoyancy imaging mechanism 31. The second driving component 342 is drivenly connected to the second sliding component 341 to at least drive the second sliding component 341 to move along a second direction.

[0099] Thus, the second sliding component 341 can serve as a fixed support structure for the buoyancy imaging mechanism 31, used to fix the buoyancy imaging mechanism 31. It can also serve as a guide structure for the buoyancy imaging mechanism 31 to move along the second direction, cooperating with the second driving component 342 to drive the buoyancy imaging mechanism 31 to move along the second direction.

[0100] For example, the second sliding component 341 includes a slide rail 3411, a second bracket 3412, and a second slider 3413. The second bracket 3412 is provided with a floating imaging mechanism 31. The second bracket 3412 is slidably connected to the slide rail 3411 through the second slider 3413. The slide rail 3411 is disposed in a predetermined structure.

[0101] For example, in this embodiment of the application, two slide rails 3411 are provided. The two slide rails 3411 are spaced apart and arranged parallel to each other on the predetermined structure. The second bracket 3412 includes two parallel second support rods 3412-a. When the floating display structure 30 cooperates with the predetermined structure with the image to be displayed, one of the second support rods 3412-a close to the predetermined structure is fixedly connected to the rotating component 35, thereby driving the entire floating imaging mechanism 31 to rotate through the rotating component 35. The second support rod 3412-a is arranged parallel to the slide rail 3411. Both ends of the second support rod 3412-a are provided with second sliders 3413. The second sliders 3413 are slidably arranged on the slide rail 3411 so that the second support rod 3412-a can drive the floating imaging structure to move along the length direction of the slide rail 3411, that is, the length direction of the slide rail 3411 is represented as the second direction.

[0102] In some embodiments, the second drive assembly 342 includes a second drive motor 3421 and a second cable 3422. The second cable 3422 is connected to the second slider 3413. The second drive motor 3421 is driven to the second cable 3422 to drive the second cable 3422 to move the second slider 3413 along a second direction.

[0103] Thus, the second drive assembly 342 uses a second drive motor 3421 in conjunction with a second cable 3422. The second cable 3422 has a certain degree of flexibility, which can buffer the impact force when the second drive motor 3421 starts or stops, reduce the vibration of the second slider 3413 and the floating imaging mechanism 31, and make the floating imaging mechanism 31 move more smoothly.

[0104] For example, the second drive motor 3421 in this application embodiment includes a linear motor. The linear motion of the linear motor drives the second cable 3422 to extend and retract, thereby driving the second slider 3413 to move. The linear motor drives the second cable 3422 directly, which can reduce losses, has a fast response speed, and is more suitable for compact space layout.

[0105] In some embodiments, the rotating assembly 35 includes a first rotating shaft 351 and a third driving assembly 352. The first rotating shaft 351 is fixedly connected to the levitation imaging mechanism 31. The third driving assembly 352 is drivenly connected to the first rotating shaft 351 to drive the first rotating shaft 351 to rotate the levitation imaging mechanism 31 relative to the moving assembly 34.

[0106] Thus, the first rotating shaft 351 is fixedly connected to the floating imaging mechanism 31 and driven by the third driving component 352. The third driving component 352 can drive the floating imaging structure to rotate around the first rotating shaft 351 as the rotation center. That is, the third driving component 352 drives the first rotating shaft 351 to rotate, and then the first rotating shaft 351 drives the floating imaging mechanism 31 to rotate relative to the moving component 34.

[0107] In some embodiments, the levitation imaging mechanism 31 is fixedly connected to the first rotating shaft 351 via a first connecting rod 354. Thus, when the first rotating shaft 351 rotates, the levitation imaging mechanism 31 can rotate via the first connecting rod 354.

[0108] In some embodiments, the first rotating shaft 351 is fixedly connected to a second support rod 3412-a near a predetermined structure via a first base 356. That is, the first rotating shaft 351 is rotatably mounted on the first base 356, and the first base 356 is fixedly connected to the second support rod 3412-a. Thus, the first base 356 provides rotational support for the first rotating shaft 351, ensuring the accuracy and smoothness of its rotation. Simultaneously, the rigid connection between the first base 356 and the second support rod 3412-a enhances the overall structural stability, ensuring the stability and reliability of the levitation imaging mechanism 31 during rotation.

[0109] In some embodiments, the floating display structure 30 further includes an interactive sensing unit 36, and the rotating component 35 further includes a second rotating shaft 353. The second rotating shaft 353 is fixedly connected to the interactive sensing unit 36. The first rotating shaft 351 and the second rotating shaft 353 are arranged parallel to each other at intervals. The third driving component 352 is drivenly connected to the second rotating shaft 353 to drive the interactive sensing unit 36 ​​and the floating imaging mechanism 31 to rotate in the same direction.

[0110] Understandably, the interactive sensing unit 36 ​​in this embodiment can transmit infrared signals within a certain area. When a user's finger or other object touches the sensing surface that transmits the infrared signal, a reflection will occur, and gesture information can then be obtained through a receiver. Figure 6 The image shows the sensing surface of the interactive sensing unit 36. When the sensing surface of the interactive sensing unit 36 ​​and the floating screen 38 are on the same plane, the floating screen 38 can be controlled by touch via the interactive sensing unit 36, such as... Figure 11 As shown, the floating sensing area 361 of the interactive sensing unit 36 ​​( Figure 11 The red part overlaps with the floating screen 38. At this time, the interactive sensing unit 36 ​​can sense the user's operation and realize the interactive control between the user and the floating screen 38, thus improving the user experience.

[0111] Thus, the second rotating shaft 353 is fixedly connected to the interactive sensing unit 36 ​​and is arranged parallel to the first rotating shaft 351 at a distance. When the third driving component 352 drives the second rotating shaft 353 to rotate, the interactive sensing unit 36 ​​and the floating imaging mechanism 31 rotate in the same direction under the synchronous action of the third driving component 352. The co-rotation of the interactive sensing unit 36 ​​and the floating imaging mechanism 31 ensures that the interactive sensing unit 36 ​​can always track the floating image 38 of the floating imaging mechanism 31, ensuring the accuracy of user interaction with the floating image 38. The parallel and spaced arrangement of the first rotating shaft 351 and the second rotating shaft 353 avoids motion interference between the floating imaging mechanism 31 and the interactive sensing unit 36, and achieves coordinated control through the same driving component, simplifying the specific structure of the floating display structure 30 in this embodiment and improving the synchronization of interaction and display.

[0112] In some embodiments, the interactive sensing unit 36 ​​is fixedly connected to the second rotating shaft 353 via a second connecting rod 355. Thus, when the second rotating shaft 353 rotates, the interactive sensor can be driven to rotate via the second connecting rod 355.

[0113] In some embodiments, the second rotating shaft 353 is fixedly connected to the second support rod 3412-a near the predetermined structure via a second base 357. That is, the second rotating shaft 353 is rotatably mounted on the second base 357, and the second base 357 is fixedly connected to the second support rod 3412-a. Thus, the second base 357 provides rotational support for the second rotating shaft 353, ensuring the accuracy and smoothness of its rotation. Simultaneously, the rigid connection between the second base 357 and the second support rod 3412-a enhances the overall structural stability, ensuring the stability and reliability of the interactive sensing unit 36 ​​during rotation.

[0114] In some embodiments, the interactive sensing unit 36 ​​has a floating sensing area 361, and the target imaging area is located within the floating sensing area 361. The floating sensing area 361 of the interactive sensing unit 36 ​​indicates the spatial range within which the interactive sensing unit 36 ​​can effectively perceive the user's gesture. Since the target imaging area is located within the floating sensing area 361, the floating image 38 is within the effective sensing range of the interactive sensing unit 36. This ensures that when the user operates on the floating image 38, the interactive sensing unit 36 ​​can accurately capture the operation, improving the accuracy and smoothness of the interaction between the user and the floating image 38, and enhancing the overall user experience of the floating display structure 30.

[0115] In some embodiments, the third drive assembly 352 includes a gear set 3521 and a drive member 3522. The gear set 3521 includes a first gear 3521-a and a second gear 3521-b. The first gear 3521-a is fixedly connected to a first rotating shaft 351, and the second gear 3521-b is fixedly connected to a second rotating shaft 353. The first gear 3521-a and the second gear 3521-b are meshed together. The drive member 3522 is drivenly connected to the first gear 3521-a to drive the first gear 3521-a to rotate.

[0116] Thus, when the driving component 3522 drives the first gear 3521-a to rotate, since the first gear 3521-a meshes with the second gear 3521-b, the first gear 3521-a will drive the second gear 3521-b to rotate synchronously. This, in turn, drives the floating imaging mechanism 31 and the interactive sensing unit 36 ​​to rotate in the same direction via the first rotating shaft 351 and the second rotating shaft 353, respectively. In this embodiment, the third driving component 352 adopts a gear transmission method, which ensures stable transmission and low power loss, thereby guaranteeing the smooth rotation of the first rotating shaft 351 and the second rotating shaft 353.

[0117] For example, the driving component 3522 includes a first motor, which is driven to rotate the first rotating shaft 351, thereby rotating the levitation imaging mechanism 31. Simultaneously, since there is a gear set 3521 between the first motor and the second rotating shaft 353, the second rotating shaft 353 also rotates under the transmission of the gear set 3521, simultaneously driving the interactive sensing unit 36 ​​to rotate. Therefore, by using the first motor, the rotation of both the levitation imaging mechanism 31 and the interactive sensing unit 36 ​​can be achieved, optimizing the structure of the levitation display structure 30 and reducing its manufacturing cost.

[0118] In some embodiments, the third drive assembly 352 includes a second motor and a third motor, the second motor being driven to drive the first rotating shaft 351 to rotate, and the third motor being driven to drive the second rotating shaft 353 to rotate.

[0119] In this way, the second motor independently drives the first rotating shaft 351 to rotate, thereby driving the floating imaging mechanism 31 to rotate, and the third motor independently drives the second rotating shaft 353 to rotate, thereby driving the interactive sensing unit 36 ​​to rotate. This achieves independent control of the rotation of the floating imaging mechanism 31 and the rotation of the interactive sensing unit 36, avoiding wear caused by using transmission components such as gear sets 3521 between the floating imaging mechanism 31 and the interactive sensing unit 36, and improving the service life of the floating display structure 30.

[0120] In some embodiments, the rotational speed of the first rotating shaft 351 is half the rotational speed of the second rotating shaft 353. In this embodiment, the floating image 38 is symmetrical to the display screen of the predetermined structure with the floating imaging lens 312 as the plane of symmetry, that is, the floating imaging lens 312 is located at the halfway point between the display screen and the floating image 38. Thus, in order to ensure that the floating sensing area 361 of the interactive sensing unit 36 ​​is always in the same plane as the floating image 38, setting the rotational speed of the first rotating shaft 351 to be half the rotational speed of the second rotating shaft 353 can ensure that the floating sensing area 361 and the floating image 38 are in the same plane, thereby improving the accuracy and sensitivity of touch on the floating image 38 of the floating display structure 30 and ensuring the accuracy of interaction.

[0121] For example, when the third drive component 352 in the embodiments of this application includes a gear set 3521 and a drive member 3522, by adjusting the gear ratio and transmission ratio of the first gear 3521-a and the second gear 3521-b of the gear set 3521, the rotational speed of the first rotating shaft 351 can be half the rotational speed of the second rotating shaft 353.

[0122] For example, when the third drive component 352 in this application embodiment uses a second motor and a third motor, by adjusting the speed ratio of the second motor and the third motor, the speed of the first rotating shaft 351 can be made to be half the speed of the second rotating shaft 353.

[0123] In some embodiments, the floating imaging lens 312 is an equivalent negative refractive index flat plate lens.

[0124] Thus, this embodiment of the application, through the negative refractive index characteristics of an equivalent negative refractive index flat lens, enables incident light to exhibit refraction behavior opposite to that of a conventional lens, refocusing divergent light to form a floating image 38 that is identical in size and content to the image to be displayed. Compared to traditional lenses, this reduces aberrations caused by the curved surface, improves the clarity of the floating image 38, and enhances the display effect of the floating display structure 30.

[0125] In some embodiments, the floating display structure 30 further includes a light-shielding component 37 disposed at the edge of the floating imaging mechanism 31.

[0126] Thus, by setting a light-shielding component 37 at the edge of the levitation imaging mechanism 31, the impact of ambient light entering the target imaging area from the edge of the levitation imaging mechanism 31 on the display effect of the levitation image 38 can be reduced, improving the clarity and viewing comfort of the levitation image 38. The light-shielding component 37 can be set at any edge position of the levitation imaging structure, but it must not affect the normal display of the levitation image 38 or the movement of the levitation imaging mechanism 31, for example, refer to Figure 3 and Figure 5As shown, in this embodiment, the light-shielding component 37 is disposed at the lower edge of the floating imaging structure to reduce the influence of external light on the floating image 38, thereby improving the display quality and effect of the floating image 38.

[0127] According to a second aspect of this application, a floating display device 20 is also provided, with reference to... Figure 5 and Figure 1 As shown, the floating display device 20 includes a display module 21 and the aforementioned floating display structure 30, with the floating display device 20 located in front of the display module 21.

[0128] It can be understood that the display module 21 in the floating display device 20 represents the predetermined device with the image to be displayed in the above embodiment. The display module 21 serves as the light source of the floating display device 20 in this embodiment. During the rotation of the floating imaging mechanism 31 of the floating display device 20 and the movement along the second direction, the position of the display module 21 does not change.

[0129] It should be noted that the floating display device 20 is located in front of the display module 21. This means that the floating display device 20 is located on the side of the display module 21 where the image to be displayed is located, and is directly opposite and spaced apart from the image to be displayed, so as to ensure that the floating display device 20 can accurately project the image to be displayed onto the target display area.

[0130] It should be noted that the floating display device 20 includes all the technical effects of the floating display structure 30 in the above embodiments. Since the technical effects of the floating display structure 30 have been described in detail above, they will not be repeated here.

[0131] In this embodiment, the floating imaging lens 312 of the display module 21 has a target position, which is configured as the distance between the upper edge of the floating imaging lens 312 and the first rotating axis 351 when the target distance is the distance.

[0132] Furthermore, when the floating imaging lens 312 is located at the target position, the angle between the floating imaging lens 312 and the display module 21 is configured as a first angle, the distance between the display module 21 and the first rotating shaft 351 is configured as a first distance, and the distance between the lower edge of the floating imaging lens 312 and the first rotating shaft 351 is configured as a second distance.

[0133] In some embodiments, the target distance is positively correlated with the first included angle; the target distance is negatively correlated with the user's optimal viewing angle; and the target distance is positively correlated with the first distance.

[0134] In some embodiments, reference Figure 10As shown, through mathematical analysis of the positional relationships between the display module 21, the first rotating shaft 351, the floating imaging lens 312, and the floating display screen, the target distance satisfies the following relationship:

[0135]

[0136] Where: X represents the target distance, α represents the first included angle, β represents the optimal viewing angle, and a represents the first distance.

[0137] In some embodiments, the controller of the floating display device 20 of this application embodiment can obtain the target distance X based on the angle between the floating imaging lens 312 and the display module 21, the distance between the display module 21 and the first rotating shaft 351, and the optimal viewing angle, through the aforementioned relationship of target distance X. Then, the first drive motor 331 of the first drive mechanism drives the floating imaging lens 312 to move along the lens frame according to the transmission distance signal provided by the controller, until the distance between the upper edge of the floating imaging lens 312 and the first rotating shaft 351 is the target distance X. At this time, the floating imaging lens 312 can completely project the image to be displayed on the display module 21 into the target display area, so that the user can view the complete floating image 38, thereby improving the display effect of the floating display device 20 of this embodiment.

[0138] In some embodiments, the second distance is positively correlated with the first angle; the second distance is positively correlated with the user's optimal viewing angle; and the second distance is positively correlated with the sum of the first distance and the height of the image to be displayed.

[0139] In some embodiments, when the rotation angle α (first included angle) of the levitation imaging mechanism 31 and the distance a (first distance) between the display module 21 and the first rotating axis 351 change, the distance Y (second distance) between the lower edge of the levitation imaging lens 312 and the first rotating axis 351 also changes synchronously. When the levitation imaging lens 312 moves to the target position, the second distance satisfies the following relationship:

[0140]

[0141] Where: Y represents the second distance, and b represents the height of the image to be displayed.

[0142] As can be seen from the above relationship, the Y value increases with the increase of the rotation angle α of the floating imaging mechanism 31 and the distance a between the display module 21 and the first rotating shaft 351. If the position of the floating imaging lens 312 does not change, the size of the floating imaging lens 312 needs to be increased to meet the requirements of different target imaging areas. Therefore, by setting a movable floating imaging lens 312, this embodiment can reduce the size of the floating imaging lens 312, lower the manufacturing cost of the floating imaging device, and make it suitable for scenarios with limited space.

[0143] In some embodiments, the height of the floating imaging lens 312 along the first direction is configured as the difference between the second distance and the target distance; the height of the floating imaging lens 312 along the first direction is positively correlated with the first included angle; the height of the floating imaging lens 312 along the first direction is positively correlated with the user's optimal viewing angle; and the height of the floating imaging lens 312 along the first direction is positively correlated with the height of the image to be displayed.

[0144] In some embodiments, reference Figure 10 As shown, the height of the buoyancy imaging lens 312 along the first direction can represent the size of the buoyancy imaging lens 312. It can be seen that the height of the buoyancy imaging lens 312 is the difference between the distance Y (second distance) between the lower edge of the buoyancy imaging lens 312 and the first rotation axis 351 and the target distance X. That is, the height of the buoyancy imaging lens 312 along the first direction satisfies the following relationship:

[0145]

[0146] Where: c represents the height of the floating imaging lens 312 along the first direction.

[0147] As can be seen from the above formula, when the rotation angle α of the floating imaging mechanism 31 (equal to the first included angle) is fixed, the height c of the floating imaging lens 312 and the distance a between the display module 21 and the first rotating shaft 351 have a negative correlation. Therefore, when a is the minimum, the maximum value of the height c of the floating imaging lens 312 can be obtained when the rotation angle α of the floating imaging mechanism 31 varies in the range of 35° to 45°.

[0148] In some embodiments, the angle α (first angle) between the floating imaging lens 312 and the display module 21 satisfies the relationship: 35°≤α≤45°. Thus, setting the angle α between the floating imaging lens 312 and the display module 21 within the range of 35° to 45° allows the user's viewing angle to be controlled between 0° and 20°. When α < 35°, the human eye needs an elevation angle greater than 20° to receive the complete imaging light, which can easily cause neck and visual fatigue, compromising viewing comfort. When α > 45°, the user needs to view from a downward angle less than 0° (i.e., looking down), which also results in poor viewing comfort.

[0149] It should be noted that the angle α between the buoyancy imaging lens 312 and the display module 21 in this embodiment can be set according to actual needs. For example, the angle α between the buoyancy imaging lens 312 and the display module 21 can be 35°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44° or 45°. Specifically, this application does not limit this.

[0150] According to a third aspect of this application, a vehicle 10 is also provided, with reference to Figure 7 and Figure 8 The vehicle 10 includes the aforementioned floating display structure 30 or floating display device 20. The vehicle 10 also includes a vehicle body, and the display module 21 of the floating display device 20 is fixedly installed inside the roof of the vehicle body.

[0151] It should be noted that the vehicle 10 includes all the technical effects of the floating display structure 30 or the floating display device 20 in the above embodiments. Since the technical effects of the floating display structure 30 and the floating display device 20 have been described in detail above, they will not be repeated here.

[0152] It is understood that the roof of vehicle 10 represents the predetermined structure in the above embodiments.

[0153] In some embodiments, the two slide rails 3411 of the moving component 34 are fixedly disposed inside the roof of the vehicle body, and the two slide rails 3411 are spaced apart along the width direction of the vehicle body. In this way, along the length direction of the vehicle body, the floating display structure 30 can be located just in front of the display module 21. In practical applications, the moving component 34 drives the floating display mechanism to move along the second direction, that is, inside the roof of the vehicle body, along the length direction of the vehicle body, to ensure that passengers can view the floating image 38 at a suitable height inside the vehicle body.

[0154] According to a fourth aspect of this application, a control method for a floating display device is also provided, applicable to the aforementioned floating display device 20, such as... Figure 13 As shown, the control method includes:

[0155] Step S100: Obtain the angle between the floating imaging lens 312 and the display module 21, the distance between the display module 21 and the first rotating shaft 351, and the optimal viewing angle;

[0156] Understandably, when using the floating display device 20 in this embodiment, when the user's viewing position 40 (human eye position) changes, in order for the user to view the floating image 38 from a better angle, it is necessary to adjust the rotation angle of the floating imaging mechanism 31 and the distance between the display module 21 and the first rotating shaft 351. That is, the floating imaging mechanism 31 is driven to move along the second direction by the moving component 34 of the second driving mechanism in this embodiment. At this time, the distance between the display module 21 and the first rotating shaft 351 changes. Since the floating image 38 and the image to be displayed on the display module 21 are symmetrical about the floating imaging glass, the change in the distance between the display module 21 and the first rotating shaft 351 will further cause the height of the floating image 38 to change simultaneously. The floating imaging mechanism 31 is driven to rotate by the rotating component 35 of the second driving mechanism to achieve the angle change of the floating image 38, meet the user's different viewing positions 40 and the needs of the optimal viewing angle, and improve the display effect and user experience of the floating display device 20 in this embodiment. Understandably, the optimal viewing angle in this embodiment is expressed as the angle between the floating image 38 and the viewing position 40 when the floating imaging lens 312 is in the target position, and the viewing effect is best within this angle.

[0157] Preferably, when using the floating display device 20 in this embodiment, the optimal viewing angle for the user is between 15° and 25°. This optimal viewing angle, set within the range of 15° to 25°, ensures that there is no obstruction between the user's viewing position 40 and the floating image 38, and also matches the comfortable viewing angle for natural human observation. For example, the optimal viewing angle can be set to 20°. At this angle, ambient light interference is minimal, image clarity and the sense of spatial suspension are strongest, and it conforms to the comfortable viewing angle for natural human observation; that is, the viewing effect is best at this angle.

[0158] In some embodiments, after the buoyancy imaging mechanism 31 moves to a position that satisfies the user's viewing position 40 and optimal viewing angle, the controller of the buoyancy imaging device obtains the angle between the buoyancy imaging lens 312 and the display module 21, and the distance between the display module 21 and the first rotating shaft 351. (Reference) Figure 9 and Figure 10 As shown, the angle α of the rotation of the levitation imaging mechanism 31 is the angle between the levitation imaging lens 312 and the display module 21. Since the levitation image 38 and the image to be displayed on the display module are symmetrical, the distance a between the display module 21 and the first rotating axis 351 is equal to the distance between the levitation image 38 and the first rotating axis 351.

[0159] In step S200, based on the angle between the floating imaging lens 312 and the display module 21, the distance between the display module 21 and the first rotating shaft 351, and the optimal viewing angle, the floating imaging lens 312 is controlled to move to the target position.

[0160] Thus, after the floating imaging lens 312 is moved to the target position, the floating imaging lens 312 can display the image to be displayed completely in the target display area, forming a floating image 38 in the target display area, so that the user can view the image in the display module 21 from the best angle at the viewing position 40, thereby improving the user's experience and viewing comfort.
