The specific structure of the storage member 30 is not limited, and it is within the scope of the present application as long as the display device a can be stored from the outside of the casing 10 into the inside of the casing 10.

Referring to fig. 2 and fig. 5 together, the imaging module 50 includes a plate lens, the imaging module 50 covers the display opening 13 formed on the housing 10, and is configured to receive the image light emitted from the display device a, focus the image light, and emit the focused image light, where the emitted image light is converged to form a real image B on a side of the imaging module 50 away from the accommodating cavity 15 (i.e., an outer side of the housing 10). Specifically, the imaging module 50 is an equivalent negative refractive index plate lens, and the image light emitted from the imaging module 50 and the image light projected onto the imaging module 50 are symmetrical with respect to the imaging module 50, so that the real image B formed by converging the image light is symmetrical with the display surface of the display device a with respect to the imaging module 50.

In this embodiment, the angle θ between the display device a and the imaging module 50 is 45 °, that is, the angle between the real image B and the imaging module 50 is also 45 °. Specifically, since the display device a and the real image B are symmetrical with respect to the imaging module 50, when the display device a and the imaging module 50 form a certain angle, the real image B also forms the same angle with the imaging module 50. By setting the included angle theta between the display device A and the imaging element to be 45 degrees, the real image B can be mapped in the air, and the observation and interaction of a user are facilitated.

Referring to fig. 6 and 7, the plate lens of the imaging module 50 includes a first transparent substrate 51, a first optical waveguide array 53, a second optical waveguide array 55 and a second transparent substrate 57 stacked in order. Wherein the arrangement directions of the optical waveguides in the first optical waveguide array 53 and the second optical waveguide array 55 are perpendicular to each other. Specifically, the arrangement direction of the optical waveguides in the first optical waveguide array 53 is parallel to the first direction X, the arrangement direction of the optical waveguides in the second optical waveguide array 55 is parallel to the second direction Y, and the first transparent substrate 51, the first optical waveguide array 53, the second optical waveguide array 55, and the second transparent substrate 57 are sequentially arranged in the third direction Z. The first optical waveguide array 53 and the second optical waveguide array 55 have the same thickness along the third direction Z, facilitating design and production.

The first transparent substrate 51 and the second transparent substrate 57 each have two optical surfaces, and the first transparent substrate 51 and the second transparent substrate 57 each have a transmittance of 90% to 100% for light having a wavelength of between 390nm and 760 nm. The material of the first transparent substrate 51 and the second transparent substrate 57 may be at least one of glass or a polymer such as plastic, acrylic, etc. for protecting the optical waveguide array and filtering out excessive light. If the strength of the first optical waveguide array 53 and the second optical waveguide array 55 after being closely and orthogonally bonded is sufficient, or if the mounting environment has a limit in thickness, only one transparent substrate may be disposed or no transparent substrate may be disposed at all.

Specifically, the first optical waveguide array 53 and the second optical waveguide array 55 are composed of a plurality of reflection units 501 having rectangular cross sections, and the length of each reflection unit 501 is limited by the outer peripheral dimension of the optical waveguide array so as to be different in length. The reflective elements 501 in the first optical waveguide array 53 extend in a first direction X and the reflective elements 501 in the second optical waveguide array 55 extend in a second direction Y. The extending directions (optical waveguide directions) of the reflecting units 501 in the first optical waveguide array 53 and the second optical waveguide array 55 are mutually perpendicular, that is, the first optical waveguide array 53 and the second optical waveguide array 55 are orthogonally arranged when seen from the third direction Z (thickness direction of the planar lens), so that two light beams in orthogonal directions are converged at one point, and the object plane and the image plane (light source side and imaging side) are ensured to be symmetrical relative to the planar lens, an equivalent negative refraction phenomenon is generated, and aerial imaging is realized.

Referring to fig. 8, the first optical waveguide array 53 or the second optical waveguide array 55 is composed of a plurality of parallel arranged reflection units 501 which are obliquely arranged to be deflected by 45 ° in the vertical direction in the user's viewing angle. Specifically, the first optical waveguide array 53 may be composed of a plurality of reflection units 501 having an included angle ω of 45 ° side by side and a rectangular cross section, the included angle ω is an included angle between the reflection units 501 and a vertical direction in a viewing angle of a user, the second optical waveguide array 55 may be composed of reflection units 501 having a rectangular cross section side by side perpendicular to the reflection units 501 in the first optical waveguide array 53, and the arrangement directions of the reflection units 501 in the two sets of optical waveguide arrays may be interchanged. For example, the reflecting units 501 in the first optical waveguide array 53 extend along the second direction Y, the reflecting units 501 in the second optical waveguide array 55 extend along the first direction X, and the first optical waveguide array 53 and the second optical waveguide array 55 are orthogonally arranged when viewed from the third direction Z (thickness direction), so that two light beams in orthogonal directions are converged at one point, and the object image plane (light source side and imaging side) is ensured to be symmetrical relative to the plate lens, an equivalent negative refraction phenomenon is generated, and aerial imaging is realized. Wherein the optical waveguide material has an optical refractive index n1, in some embodiments n1>1.4, e.g., n1 has a value of 1.5, 1.8, 2.0, etc.

Referring to fig. 9, for the first optical waveguide array 53 and the second optical waveguide array 55, two interfaces exist between each reflecting unit 501 and its adjacent reflecting unit 501, and the interfaces are bonded by an adhesive 503 with better light transmittance. The adhesive 503 may be a photosensitive adhesive or a thermosetting adhesive, and the thickness of the adhesive 503 is greater than 0.001mm, for example, 0.002mm, 0.003mm or 0.0015mm, and the specific thickness may be set according to specific needs. An adhesive 503 (not shown) may be disposed between adjacent optical waveguide arrays in the imaging module 50 and between the optical waveguide arrays and the transparent substrate to increase the firmness.

The cross section of the reflection unit 501 may be rectangular, and one or both sides along the arrangement direction of the reflection unit 501 are provided with reflection films 502. Specifically, in the arrangement direction of the optical waveguide array, both sides of each reflecting unit 501 are plated with a reflecting film 502, and the material of the reflecting film 502 may be a metal material such as aluminum or silver or other nonmetallic compound materials for realizing total reflection. The reflective film 502 functions to prevent stray light from entering the adjacent optical waveguide array due to the lack of total reflection from affecting imaging. Or each reflection unit 501 may be formed by adding a dielectric film to the reflection film 502 to increase the light reflectance.

The individual reflecting elements 501 have a cross-sectional width of 0.1mm-5mm and a cross-sectional length of 0.1mm-5mm. For better imaging effect, the cross section width can be 0.1mm-2mm, and the cross section length can be 0.1mm-2mm. For example, the cross-sectional width is 0.2mm, the cross-sectional length is 0.2mm, or the cross-sectional width is 0.5mm, and the cross-sectional length is 0.5mm. The large-size requirement can be realized by splicing a plurality of optical waveguide arrays during large-screen display. The overall shape of the optical waveguide arrays is set according to the application scene requirement, in this embodiment, the two groups of optical waveguide arrays are in rectangular structures, the reflective units 501 of two opposite angles are triangles, and the reflective unit 501 in the middle is in a trapezoid structure. The lengths of the individual reflection units 501 are unequal, the reflection units 501 located on the diagonal of the rectangle are longest, and the reflection units 501 at both ends are shortest. In addition, the imaging module 50 may further include an anti-reflection component and a viewing angle control component (not shown), where the anti-reflection component may increase the overall transmittance of the plate lens, and increase the sharpness and brightness of the real image B. The visual angle control part can be used for eliminating the residual image of the real image B, reduces the dizziness of the observer, prevents the observer from peeping into the device from other angles at the same time, and improves the overall aesthetic degree of the device. The anti-reflection component and the visual angle control component can be combined, or can be respectively and independently arranged between the transparent substrate and the waveguide array, between two layers of waveguide arrays or on the outer layer of the transparent substrate.

The principle of aerial imaging is explained below. On the micrometer scale, a mutually orthogonal double-layer waveguide array structure is used to perform orthogonal decomposition on any optical signal. The original signal is projected on the first optical waveguide array 53, and a rectangular coordinate system is established with the original signal projection point as an origin and the X axis perpendicular to the first optical waveguide array 53, and in the rectangular coordinate system, the original signal is decomposed into two paths of mutually orthogonal signals, namely, a signal X located on the X axis and a signal Y located on the Y axis. Wherein the signal X is totally reflected on the surface of the reflective film 502 at the same reflection angle as the incident angle while passing through the first optical waveguide array 53; at this time, the signal Y is kept parallel to the first optical waveguide array 53, and after passing through the first optical waveguide array 53, the signal Y is totally reflected on the surface of the reflective film 502 at the same reflection angle as the incident angle on the surface of the second optical waveguide array 55, and the reflected optical signal formed by the reflected signal Y and the signal X is mirror-symmetrical to the original optical signal. Therefore, the light rays in any direction can be mirror-symmetrical through the imaging module 50, the divergent light rays of any light source can be refocused into a real image at a symmetrical position through the imaging module 50, the imaging distance of the real image B is equal to the distance from the imaging module 50 to the image source, namely the display device A, the real image B is imaged at equal distances, and the position of the real image B is in the air without a specific carrier, but the real image is directly presented in the air. Therefore, the image in the space seen by the user is formed by condensing the image light emitted from the display device a.

In the present embodiment, the image light emitted from the display device a passes through the imaging module 50, and the above-described process occurs on the imaging module 50. Specifically, referring to fig. 10, the incident angles of the image light on the first optical waveguide array 53 are α1, α2, and α3, respectively, the reflection angles of the image light on the first optical waveguide array 53 are β1, β2, and β3, wherein α1=β1, α2=β2, α3=β3, the incident angles on the second optical waveguide array 55 are γ1, γ2, and γ3, respectively, after being reflected by the first optical waveguide array 53, and the reflection angles on the second optical waveguide array 55 are δ1, δ2, and δ3, respectively, wherein γ1=δ1, γ2=δ2, γ3=δ3.

Further, the incident angles after convergence imaging are α1, α2, α3 … αn, and the distance between the display device a and the imaging module 50 is L, so that the distance between the imaging position of the real image B and the imaging module 50 is L, and the viewing angle of the real image B is 2 times max (α).

It will be appreciated that if the size of the optical waveguide array is small, the image will only be visible at a distance from the imaging side of the optical waveguide array; and if the size of the optical waveguide array becomes larger, a larger imaging distance can be realized, so that the field of view is increased.

The thicknesses of the first optical waveguide array 53 and the second optical waveguide array 55 are the same, so that the complexity of the structures of the first optical waveguide array 53 and the second optical waveguide array 55 can be simplified, the manufacturing difficulty of the first optical waveguide array 53 and the second optical waveguide array 55 is reduced, the production efficiency of the first optical waveguide array 53 and the second optical waveguide array 55 is improved, and the production cost of the first optical waveguide array 53 and the second optical waveguide array 55 is reduced. It should be noted that the thicknesses are the same in a relative range, and not the same in absolute terms, i.e., for the purpose of improving the production efficiency, a certain thickness difference may exist between the optical waveguide arrays without affecting the aerial imaging quality.

In other embodiments, the imaging module 50 may also have other structures, for example, the imaging module 50 only includes one layer of optical waveguide array, and the plurality of cubic columnar reflection units with reflection films on four peripheral surfaces are arranged in an array along the first direction X and the second direction Y in the one layer of optical waveguide array structure, that is, two layers of optical waveguide arrays are combined into one layer, and the imaging principle is the same as that of the two-layer optical waveguide array structure.

The vehicle-mounted aerial imaging device 100 provided by the embodiment of the application can be used for accommodating the display device A by arranging the shell 10 and the storage piece 30, so that the display device A is prevented from falling off in the driving process, and the driving safety is improved. Through setting up imaging module 50, can throw the content that display device A shows in the sky, form aerial real image B, be favorable to the user to observe display device A's content, have stronger technological sense.

Specifically, the housing 210 and the case 10 may be directly integrally formed during the manufacturing process, such that the case 10 forms a part of the housing 210, and the imaging module 50 directly covers the housing 210, thereby reducing the manufacturing process.
