Abstract
Description
Technical Field
[0001] This utility model relates to the field of display technology, and more specifically, to an aerial imaging device. Background Technology
[0002] The main principle of aerial imaging devices is that images are generated from image sources such as displays, and then formed into real images in the air after passing through optical elements such as lenses. Due to their unique levitation experience, aerial imaging devices have been widely used in smart home, office, and automotive applications.
[0003] Currently, most common aerial levitation imaging devices use lenses that are tilted relative to the display screen for easier imaging. This results in the levitation image and the lens typically having a 45° angle. Consequently, users can always directly observe the lens behind the levitation image, leading to a weak levitation experience. Furthermore, the imaging position of most aerial imaging devices is fixed, meaning users can only see the levitation image from a fixed direction. It is not visible from the sides or back, which is quite restrictive and significantly impacts user comfort. In addition, most current aerial imaging devices are composed of multiple stacked structures, making their overall structure complex, difficult to manufacture and assemble, and resulting in high costs. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide an aerial imaging device with a simple structure, low cost, strong levitation experience and high user comfort.
[0005] This utility model provides an aerial imaging device, comprising: a lens, including a light-guiding surface and an exiting surface arranged opposite to each other, wherein the light-guiding surface is provided with a plurality of spaced-apart light-guiding teeth, each light-guiding tooth including an incident surface and a reflecting surface, wherein the reflecting surface is perpendicular to the incident surface and the exiting surface respectively; a display screen, disposed on one side of the light-guiding surface of the lens and perpendicular to the lens; and a control component configured to be rotatable, wherein the control component can drive the lens and the display screen to rotate.
[0006] In the above scheme, the reflecting surface is perpendicular to both the incident and exit surfaces, meaning the incident and exit surfaces are parallel. The lens is placed horizontally. The light emitted from the display screen passes sequentially through the incident, reflecting, and exit surfaces, converging in the air to form a suspended image. The formed suspended image and the original image on the display screen are located on opposite sides of the lens. By controlling the distance between the display screen and the lens, the formed suspended image can be kept at a certain distance from the lens to achieve a completely suspended effect, resulting in a strong sense of suspension and improving the user experience. Furthermore, since the display screen and the lens are set perpendicularly, the formed suspended image forms a 90° angle with the lens, further enhancing the suspension experience. In addition, the control components can drive the lens and display screen to rotate around the center of the lens, thereby adjusting the position of the suspended image for viewing from different directions, improving practicality and user experience.
[0007] In one example of this utility model, the reflecting surface is an arc-shaped surface in the shape of a circular arc or an elliptical arc; when the reflecting surface is a circular arc surface, multiple reflecting surfaces are arranged concentrically at intervals according to their corresponding centers; when the reflecting surface is an elliptical arc surface, multiple reflecting surfaces are arranged at intervals according to their corresponding elliptical focal points; the two ends of the reflecting surface extend to the edge of the lens.
[0008] In the above scheme, the reflective surface is a curved surface in the shape of a circular arc or an elliptical arc. Therefore, when viewed from a direction perpendicular to the light guide surface of the lens, the light guide teeth are in the shape of a circular arc or an elliptical arc, and are arranged concentrically or at the same focal point. The light emitted by the display screen eventually converges to the position directly above the center or focal point of each reflective surface, forming a floating image in the air. By setting the reflective surface as a curved surface, compared with a flat surface, it helps to make the clarity and three-dimensionality of the floating image in the air stronger. In addition, the two ends of the reflective surface are connected to the edge of the lens to fully capture the light emitted by the display screen and avoid omissions. When dealing with the imaging of a floating image with a wide width, it can effectively ensure the integrity of the imaging.
[0009] In one example of this utility model, the lens is circular, the center or focal point corresponding to the reflecting surface falls on the outer periphery of the lens, and the display screen is disposed on one side of the center or focal point corresponding to the reflecting surface.
[0010] In the above scheme, the display screen is located below the center or focal point corresponding to the reflective surface, and the suspended image formed by the lens is located above the center or focal point.
[0011] In one example of this utility model, the cross-section of the light guide tooth is a right-angled trapezoid or a rectangle.
[0012] In the above scheme, both the right trapezoid and the rectangle have parallel sides and right-angled sides perpendicular to the parallel sides, so as to serve as the incident surface and the reflecting surface through which the light from the display screen passes.
[0013] In one example of this invention, the distance between the reflective surfaces of adjacent light-guiding teeth is less than 1 mm.
[0014] In one example of this utility model, the control component includes a rotating platform and a mounting ring. The lens and the rotating platform are respectively mounted at both ends of the mounting ring. The rotating platform is connected to a rotation drive component, and the display screen is mounted on the inner wall of the mounting ring.
[0015] In the above solution, by installing the lens and the rotating stage at both ends of the mounting ring, a closed structure is formed, which achieves the effect of waterproofing and dustproofing, protecting the internal display screen. The mounting ring can also prevent external light from affecting the image on the internal display screen, ensuring the imaging effect. In addition, when the rotating stage rotates, it can drive the mounting ring and the lens to rotate together. Since the display screen is installed on the inner wall of the mounting ring, the lens and the display screen remain relatively stationary during rotation, so that the suspended image formed by the lens and the display screen can change position together with the rotation of the rotating stage, realizing the need for multi-directional viewing. At the same time, it can also prevent the position of the lens and the display screen from shifting, avoiding affecting the imaging.
[0016] In one example of this utility model, the control component further includes a base and a control motherboard. The rotary table is rotatably mounted on the base, and a cavity is formed between the rotary table and the base to accommodate the rotary drive and the control motherboard. The control motherboard is electrically connected to the rotary drive and the display screen.
[0017] In the above solution, the control motherboard is electrically connected to the rotary drive and the display screen to control the rotation angle of the rotary table and the image output of the display screen. The rotary drive and the control motherboard are located in the cavity between the rotary table and the base, making the overall structure more compact and reducing the space occupied. At the same time, it can also play a waterproof and dustproof role, protecting the control motherboard.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] This utility model consists only of a lens, a display screen, and control components. Its structure is simple, and each part is easy to manufacture and obtain, which can effectively reduce costs.
[0020] This invention places the display screen vertically on one side of the lens. By controlling the distance between the display screen and the lens, the formed suspended image in the air can be kept at a certain distance from the lens to achieve a completely suspended effect with a strong sense of suspension. Furthermore, the formed suspended image can be made to form a 90° angle with the lens, so the lens cannot be directly observed behind the suspended image, which can further enhance the sense of suspension and improve the user experience.
[0021] This invention, by setting up a control component, can drive the lens and display screen to rotate around the center of the lens, thereby adjusting the formation position of the suspended image in the air for users to view from different directions, effectively improving the user experience and comfort, and enhancing the sense of technology.

Detailed Implementation
[0033] To facilitate understanding of this invention, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Example 1
[0034] Please refer to Figures 1 to 6 This embodiment provides an aerial imaging device, which includes a lens 1, a display screen 2, and a control component 3. The lens 1 includes a light-guiding surface and an exiting surface 11 disposed opposite to each other. The light-guiding surface has multiple spaced-apart light-guiding teeth 12, each light-guiding tooth 12 including an incident surface 121 and a reflecting surface 122, the reflecting surface 122 being perpendicular to both the incident surface 121 and the exiting surface 11. The display screen 2 is disposed on one side of the light-guiding surface of the lens 1 and is perpendicular to the lens 1. The control component 3 is rotatable and is used to drive the lens 1 and the display screen 2 to rotate.
[0035] It should be noted that, as Figure 1 As shown, lens 1 is placed horizontally, with its top surface being the emission surface 11 and its bottom surface being the light guide surface.
[0036] Please refer to Figures 3 to 5 , Figure 3 and Figure 4 The change in direction of light as it passes through the light guide tooth 12, such as Figure 4 As shown, the light emitted from the display screen 2 passes sequentially through the incident surface 121, the reflecting surface 122, and the exit surface 11, and then converges in the air to form a suspended image, wherein, as shown... Figure 3 and Figure 5 As shown, the formed suspended image X and the original image Y of the display screen 2 are located on the upper and lower sides of the lens 1, respectively. By controlling the distance between the display screen 2 and the lens 1, the formed suspended image in the air can be kept at a certain distance from the lens 1 to achieve a completely suspended effect, resulting in a strong sense of suspension and improving the user experience. Furthermore, since the display screen 2 and the lens 1 are set perpendicularly, the formed suspended image and the lens 1 form a 90° angle, so users will not directly see the lens 1 behind the suspended image when viewing it, which can further enhance the sense of suspension. In addition, the control component 3 can drive the lens 1 and the display screen 2 to rotate around the center of the lens 1, thereby adjusting the position of the suspended image for users in different directions to view, which improves practicality and user experience.
[0037] Furthermore, referring to Figure 6 Viewed from the light-guiding surface of lens 1, the light-guiding tooth 12 is arc-shaped, and the reflecting surface 122 on it is an arc-shaped curved surface. Multiple reflecting surfaces 122 are arranged concentrically at intervals according to the centers of their corresponding arc surfaces (hereinafter referred to as the imaging centers for ease of description). Lens 1 is circular, as shown below. Figure 6In the indicated direction, the imaging center M falls on the left end of the outer periphery of lens 1, and the display screen 2 is located directly below the imaging center M. The light emitted by the display screen 2 eventually converges to the position directly above the imaging center M, forming a suspended image in the air. By setting the reflective surface 122 as a curved surface, compared with a flat surface, it helps to make the clarity and three-dimensionality of the suspended image in the air stronger. In addition, the two ends of the reflective surface 122 are connected to the edge of lens 1 to fully capture the light emitted by the display screen 2 and avoid omissions. When dealing with the imaging of a suspended image with a wide width, it can effectively ensure the integrity of the image.
[0038] Preferably, in order to cooperate with the arc-shaped reflective surface 122 for imaging, the display screen 2 is a flexible curved screen. The display screen 2 can be a liquid crystal panel, OLED screen or LED display screen 2, etc., and the specific selection is based on actual needs. Flexible display screen 2 is commonly used in the display field, and its specific structure and principle will not be described in detail here.
[0039] Preferably, to ensure the stability and quality of imaging, the light guide teeth 12 are distributed at the same interval, and the distance between the reflective surfaces 122 of adjacent light guide teeth 12 is less than 1 mm.
[0040] It should be noted that lens 1 is made of a material with good light transmittance, such as acrylic, PC or glass. It is formed by precision mold hot pressing or high-speed laser engraving to form light guide teeth 12 on the surface. The material of lens 1 is easy to obtain, which can effectively reduce costs.
[0041] Preferably, the thickness of lens 1 is less than 10 mm.
[0042] Please refer to Figure 4 The cross-section of the light guide tooth 12 is a right trapezoid or a rectangle. Both the right trapezoid and the rectangle have parallel sides and right-angled sides perpendicular to the parallel sides, so as to serve as the incident surface 121 and the reflecting surface 122 through which the light of the display screen 2 passes. Preferably, the cross-section of the light guide tooth 12 in this embodiment is a right trapezoid.
[0043] Please refer to Figure 1 The control component 3 includes a rotating platform 31 and a mounting ring 4. The lens 1 and the rotating platform 31 are respectively mounted at both ends of the mounting ring 4. The rotating platform 31 is connected to a rotation drive (not specifically shown in the figure). The display screen 2 is mounted on the inner wall of the mounting ring 4.
[0044] By mounting the lens 1 and the rotating stage 31 at both ends of the mounting ring 4, the interior of the mounting ring 4 is sealed, achieving a waterproof and dustproof effect, protecting the internal display screen 2. The mounting ring 4 can also prevent external light from affecting the image on the internal display screen 2, ensuring imaging quality. When the rotating stage 31 rotates, it can drive the mounting ring 4 and the lens 1 to rotate together. Since the display screen 2 is mounted on the inner wall of the mounting ring 4, the lens 1 and the display screen 2 remain relatively stationary during rotation, so that the display screen 2 is always located below the imaging center M of the lens 1. This allows the formed suspended image to change position along with the rotation stage 31, meeting the needs of multi-directional viewing. At the same time, it can also prevent the relative position of the lens 1 and the display screen 2 from shifting, avoiding affecting imaging.
[0045] Preferably, the outer periphery of the lens 1 is sealed and bonded to the mounting ring 4 with adhesive, which helps to improve the waterproof effect. The mounting ring 4 and the rotating table 31 can be bonded with adhesive, or they can be connected by welding or other means.
[0046] Furthermore, referring to Figure 5 To facilitate observation of the internal structure, Figure 5 The mounting ring 4 has been hidden. The control component 3 also includes a base 32 and a control motherboard (not specifically shown in the figure). The rotating stage 31 is rotatably mounted on the base 32. A cavity is formed between the rotating stage 31 and the base 32 to accommodate the rotating drive and the control motherboard. The control motherboard is electrically connected to the rotating drive, thereby controlling the rotation angle of the rotating stage 31 and adjusting the orientation of the suspended image in the air. At the same time, the control motherboard is electrically connected to the display screen 2 to control the image output of the display screen 2. The rotating drive and the control motherboard are located in the cavity between the rotating stage 31 and the base 32, making the overall structure more compact and reducing the space occupied. At the same time, it can also play a waterproof and dustproof role, protecting the control motherboard.
[0047] It should be noted that the display screen 2 is connected to the control motherboard via wires or connectors, and the rotating disk is provided with holes or slots for the wires or connectors to pass through. Example 2
[0048] Please refer to Figure 7 This embodiment is basically the same in structure and principle as Embodiment 1. The difference is that, in this embodiment, the light guide tooth 12, viewed from the light guide surface of the lens 1, is elliptical in shape, and the reflecting surface 122 on it is an elliptical curved surface. Multiple reflecting surfaces 122 are arranged at intervals according to the focal points (hereinafter referred to as imaging focal points for ease of description) corresponding to their elliptical curved surfaces, such as... Figure 7 In the indicated direction, the imaging focus N falls on the left end of the outer periphery of lens 1, the display screen 2 is located below the imaging focus N, and the final suspended image is located above the imaging focus N. Example 3
[0049] Please refer to Figure 8 This embodiment is basically the same in structure and principle as Embodiment 1 and Embodiment 2. The difference is that the display screen 2 in this embodiment is a ring display screen 2 with the ends connected. Its inner surface is the display surface. The rotating table 31 is provided with several connecting rods 5. The connecting rods 5 are connected to the lens 1. The rotating table 31 drives the lens 1 to rotate through the connecting rods 5.
[0050] In this embodiment, the display screen 2 is mounted on the base 32 and arranged around the rotating platform 31. It does not rotate with the rotating platform 31. The display screen 2 can automatically switch the display position of the image, such as... Figure 8 As shown, when the rotating stage 31 drives the lens 1 to rotate into position, under the control of the main control board, the original image Y on the display screen 2 is switched to be displayed below the imaging center M or imaging focus N on the lens 1, thereby forming a suspended image X in the air above.
[0051] It is understood that lens 1 in this embodiment can be selected from... Figure 6 The lens shown can also be selected Figure 7 The lens shown.
[0052] It should be noted that, Figure 8 The mounting ring is hidden. In this embodiment, the mounting ring 4 is mounted on the base 32 and is not connected to the lens 1 and the display screen 2, or is rotatably connected. Example 4
[0053] This embodiment provides an imaging control method, which employs the aerial imaging device described in the above embodiment, and includes the following steps:
[0054] S1: Control component 3 acquires the position to be imaged and the current position of lens 1;
[0055] S2: The control component 3 drives the lens 1 and the display screen 2 to rotate, so that the lens 1 and the display screen 2 move to the position to be imaged;
[0056] S3: Display screen 2 is turned on, and a suspended image is formed in the air at the position to be imaged through lens 1.
[0057] Specifically, after acquiring the data of the position to be imaged and the current position of the lens 1, the control component 3 calculates the angle required for the lens 1 and the display screen 2 to move to the position to be imaged. Then, the control component 3 drives the rotating stage 31 to rotate, so that the lens 1 and the display screen 2 move to the center of the position to be imaged. Then, the control component 3 controls the display screen 2 to play the image, thereby forming an aerial levitation image at the position to be imaged. In actual use, the levitation image can be adjusted to face the user according to the user's location, so that multi-directional viewing can be achieved, improving the user experience and comfort.
[0058] It is understood that when using an aerial imaging device as in Embodiment 3, since the display screen 2 is ring-shaped, the rotating stage 31 only needs to move the imaging center M or imaging focus N on the lens 1 to the position to be imaged. After the lens 1 is moved into place, the display screen 2 automatically switches the image to be displayed below the imaging center M or imaging focus N under the control of the control component 3, so as to form an aerial levitation image.
[0059] In this embodiment, in S1, the external sensing device (not specifically shown in the figure) can acquire the user's current position data and the lens 1's current position data, and transmit the data to the control component 3. The control component 3 reacts according to the received data, so that the formed aerial levitation image automatically faces the user's direction, improving the comfort during use.
[0060] It should be noted that the external sensing device consists of multiple sensors working together, such as motion sensors and sensors with image recognition capabilities, which can successfully acquire the required position data. In addition to using external sensing devices, the position of the aerial levitation image can also be adjusted by the user inputting the rotation angle, thereby improving its practicality.
[0061] In S3, the display screen 2 illuminates a single column of pixels each time. By cyclically illuminating the single column of pixels that make up the image, a complete suspended image is formed by utilizing the persistence of vision. By illuminating a single column of pixels each time, the display screen 2 can effectively reduce its power consumption and extend its lifespan.
[0062] In other embodiments, in S3, the display screen 2 illuminates multiple columns of pixels each time. By cyclically illuminating multiple columns of pixels in sequence, a floating image is formed in the air using the persistence of vision effect. Alternatively, the display screen 2 can also illuminate all columns of pixels containing the image at the same time to directly display the complete image, which is then used by the lens 1 to generate a floating image, thus achieving the same imaging effect.
[0063] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0064] Furthermore, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.
