Description

Vehicle trim TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of vehicle parts. More particularly, the present disclosure relates to a vehicle trim. BACKGROUND

[0002] The common depth-of-field light effect in the market at present is achieved by means of a half-reflective half-transmissive film and a full-reflective film, which realizes multi-layer reflection and transmission of images or light between the two film layers, thereby forming a depth-of-field effect. Specifically, a pattern is arranged between the two film layers, light emitted by a light source is reflected and diffracted in various directions after irradiating the pattern, the light reaches the underlying full-reflective film, the entire light path is fully reflected, the light reaches the half-reflective half-transmissive film upwards, part of the light is seen after being transmitted through the half-reflective half-transmissive film, and the other part of the light is reflected downwards again to the underlying full-reflective film for full transmission. This process is repeated N times of half-transmission and full-reflection, so that the optical pattern observed by the human eye at one observation position has the effect of overlapping depth-of-field (i.e. gradually fading layers).

[0003] In the case where the full-reflective film and the half-reflective half-transmissive film are both planar or smooth curved surfaces, the overlapping shadows observed by the human eye are regularly arranged, for example, at equal intervals one circle after another, and gradually fade one circle after another, i.e. gradually fade. As an expression of the depth-of-field effect, the regular depth-of-field has a very broad prospect in the field of vehicle applications. In order to apply this regular depth-of-field effect more to vehicle trims to increase the aesthetic degree, it is necessary to make further analysis and research on various rules of this light effect and the structure levels, relationship parameters corresponding to these rules.

DETAILED DESCRIPTION

[0071] The implementation and use of specific embodiments are discussed in detail below. It should be appreciated that the specific embodiments discussed are merely illustrative of specific ways to implement and use the presently disclosed subject matter and do not limit the scope of the presently disclosed subject matter.

[0072] As shown in FIG. 1A, the vehicle trim according to the present disclosure can be installed on the exterior of the vehicle, which can be particularly applied to the front bumper FB including the grille, the rear bumper RB, the roof RF, the trim RP, the fender FD, the tailgate TG, the side door SD, or the side wall SB, etc. As shown in FIGS. 1B-1D, the vehicle trim according to the present disclosure can also be installed on the interior of the vehicle, which can be particularly applied to the instrument panel IP, the front and rear door DP, or the auxiliary instrument panel CS, and can also be applied to the in-roof CE to provide, for example, a starry sky roof, and can also be applied to the headrest HR, the seat armrest SA, or the seat back SK, etc.

[0073] First Embodiment

[0074] As shown in FIG. 2A, the vehicle trim according to the first embodiment includes a direct type light source 210, a transparent framework 300, a semi-reflective and semi-transmissive layer 310, a total reflection layer 320, and an optical pattern 330, wherein the top surface 340 and the bottom surface 350 of the transparent framework 300 are two parallel planes, the semi-reflective and semi-transmissive layer 310 is attached to the top surface 340 of the transparent framework 300, the total reflection layer 320 is attached to the bottom surface 350 of the transparent framework 300, the optical pattern 330 is a light-transmitting hollow structure formed on the total reflection layer 320, and the direct type light source 210 is located on the side of the total reflection layer 320 away from the semi-reflective and semi-transmissive layer 310 to illuminate the transparent framework 300.

[0075] The present disclosure utilizes the optical total reflection mechanism of the total reflection layer 320 and the partial light reflection and partial light transmission mechanism of the semi-reflective and semi-transmissive layer 310, so that the designed optical pattern 330 generates patterned light rays after being illuminated by the direct type light source 210, which propagate between the semi-reflective and semi-transmissive layer 310 and the total reflection layer 320. When the light rays of the optical pattern 330 encounter the semi-reflective and semi-transmissive layer 310 during propagation, they will partially transmit and partially reflect, and due to the partial transmission of light rays and energy loss during reflection, the light rays of the optical pattern 330 reflected back by the semi-reflective and semi-transmissive layer 310 will experience brightness attenuation. When the light rays of the optical pattern 330 encounter the total reflection layer 320 during propagation, they will undergo total reflection, and due to the optical total reflection, the brightness of the reflected light rays should theoretically be the same as that of the unreflected light rays, but due to the manufacturing of the actual reflection layer, the brightness of the reflected light rays will experience a small brightness attenuation. Thus, the light rays of the optical pattern 330 will undergo multiple transmissions and reflections between the semi-reflective and semi-transmissive layer 310 and the total reflection layer 320, thereby forming a depth of field visual effect with multiple images arranged in sequence and gradually fading in brightness.

[0076] In the first embodiment, when the light from the direct light source 210 is irradiated towards the bottom surface 350 of the transparent skeleton 300, the light emitted from the direct light source 210 will illuminate the light-emitting optical pattern 330 after passing through the optical pattern 330. The light propagating between the semi-reflective and semi-transmissive layer 310 and the total reflection layer 320 can be seen to propagate along the light ray transmission path 410, which is directly observed by the observer 100 after passing through the semi-reflective and semi-transmissive layer 310, i.e. the light-emitting image A in the figure. The light propagating along the light ray transmission path 420 is reflected once at the semi-reflective and semi-transmissive layer 310, reflected once at the total reflection layer 320, and finally transmitted through the semi-reflective and semi-transmissive layer 310 to be observed by the observer 100. Since the light observed by the observer 100 is reflected between the semi-reflective and semi-transmissive layer 310 and the total reflection layer 320, the image observed by the eye of the observer 100 at this time is a virtual image B, and the imaging path of the virtual image B is: the light-emitting image A is reflected by the semi-reflective and semi-transmissive layer 310 to obtain a virtual image B', and the virtual image B' is reflected by the total reflection layer 320 to obtain a virtual image B. Similarly, the light propagating along the light ray transmission path 430 is reflected twice at the semi-reflective and semi-transmissive layer 310, reflected twice at the total reflection layer 320, and finally transmitted through the semi-reflective and semi-transmissive layer 310 to be observed by the observer 100. Since the light observed by the observer 100 is reflected between the semi-reflective and semi-transmissive layer 310 and the total reflection layer 320, the image observed by the eye of the observer 100 at this time is a virtual image C, and the imaging path of the virtual image C is: the light-emitting image A is reflected by the semi-reflective and semi-transmissive layer 310 to obtain a virtual image B', the virtual image B' is reflected by the total reflection layer 320 to obtain a virtual image B, the virtual image B is reflected by the semi-reflective and semi-transmissive layer 310 to obtain a virtual image C', and the virtual image C' is reflected by the total reflection layer 320 to obtain a virtual image C. Thus, the observer 100 finally sees the images A, B, C… with gradually decreasing brightness and regular depth of field effect.

[0077] When the semi-reflective and semi-transmissive layer 310 and the total reflection layer 320 are in a parallel relationship as shown in FIG. 2A, and the semi-reflective and semi-transmissive layer 310 and the total reflection layer 320 are planar or smooth curved surfaces with continuous curvature, the light-emitting optical pattern 330 will exhibit a regular depth of field effect similar to the images A, B, C shown in FIG. 2A after multiple transmissions and reflections between the semi-reflective and semi-transmissive layer 310 and the total reflection layer 320, i.e. equal spacing between adjacent images, same shape and gradually decreasing brightness, and the stereoscopic visual reference effect is shown in FIG. 2B.

[0078] The direct type light source 210 can be a matrix type LED PCB light plate, or can be a light guide strip, light guide plate, light homogenizing film, light homogenizing plate, light emitting film, or light emitting optical fiber, etc. that can emit light after being irradiated by the light source. It should be understood that the direct type light source 210 can be a surface light source or a point light source, as long as part of the light of the light source can pass through the hollow structure on the total reflection layer 320.

[0079] The transparent skeleton 300 is a single piece formed by a thick wall injection molding process (the wall thickness is usually 1-11 mm), and the material includes but is not limited to PC (polycarbonate), PMMA (polymethyl methacrylate), and other transparent injection molding materials, and the color can be colorless transparent or colored transparent.

[0080] The semi-reflective and semi-transmissive layer 310 can be combined with the top surface 340 of the transparent skeleton 300 by pasting a semi-reflective and semi-transmissive film, spraying or brushing a semi-reflective and semi-transmissive coating, PVD (physical vapor deposition), or using an additional part with semi-reflective and semi-transmissive properties.

[0081] The total reflection layer 320 can be combined with the bottom surface 350 of the transparent skeleton 300 by spraying, silk printing, pasting a film, electroplating, hot stamping, or PVD process, or the bottom surface 350 of the transparent skeleton 300 can be configured to be optically totally reflective, or it can be combined with the bottom surface 350 of the transparent skeleton 300 by an additional part with total reflection properties.

[0082] The optical pattern 330 is realized by engraving, punching, local shielding + total reflection surface treatment (in this case, the total reflection surface substrate is assumed to be pure transparent or semi-transparent, and the shielding area is transparent due to not being subjected to total reflection surface treatment) or printing a point, line or facet pattern that can be directly illuminated by light on the total reflection layer 320 combined with the bottom surface 350 of the transparent skeleton 300.

[0083] In a variant of the first embodiment, the transparent skeleton 300 is replaced by an upper skeleton 360 and a lower skeleton 370 as shown in FIG. 6A. The top surface or bottom surface of the upper skeleton 360 is combined with the semi-reflective and semi-transmissive layer 310, and the top surface or bottom surface of the lower skeleton 370 is combined with the total reflection layer 320, and the surface of the upper skeleton 360 combined with the semi-reflective and semi-transmissive layer 310 and the surface of the lower skeleton 370 combined with the total reflection layer 320 are both flat or smooth curved surfaces with continuous curvature. The combination of the upper skeleton 360 and the lower skeleton 370 has the same functions as the transparent skeleton 300 described above in the present disclosure, and is convenient to adapt to the weight, space arrangement, cost and other requirements of different use occasions.

[0084] When the half-reflecting half-transmitting layer 310 and the total reflecting layer 320 are in parallel relationship as shown in FIG. 6A, and the half-reflecting half-transmitting layer 310 and the total reflecting layer 320 are planar or curvature-continuous smooth curved surfaces, the optical pattern 330 emitted will present regular depth of field similar to the images M, N, O shown in FIG. 6A after multiple transmissions and reflections along different light ray propagation paths 4130, 4140, 4150 between the half-reflecting half-transmitting layer 310 and the total reflecting layer 320, i.e. the depth of field visual effect (the imaging principle of the virtual images N' and O' is similar to that of B' and C' described above) of equal spacing between adjacent images, same shape and gradually fading brightness.

[0085] The upper skeleton 360 and the lower skeleton 370 are formed by a common injection molding (usually with a wall thickness of 1-11 mm) process, and the material can be a transparent injection molding material including but not limited to PC, PMMA, etc. The color of the upper skeleton 360 can be colorless transparent or colored transparent, and the color of the lower skeleton 370 can be colorless transparent or colored transparent, or colorless translucent or colored translucent.

[0086] In this variant, the lower skeleton 370 can also be a non-transparent piece, and its color can be any color of non-transparent. In this case, the total reflecting layer 320 is overlaid with the top surface of the lower skeleton 370, and at this time the optical pattern 330 can be realized by making an opening on the assembly after the lower skeleton 370 is overlaid with the total reflecting layer 320. The opening can be realized by punching or laser opening directly on the assembly after the lower skeleton 370 is overlaid with the total reflecting layer 320, or the lower skeleton 370 can be pre-opened by mold injection when the lower skeleton 370 is injection molded, and the total reflecting layer 320 is also treated with light-transmitting at the corresponding position and overlaid with the lower skeleton 370. At this time, the light-transmitting treatment of the total reflecting layer 320 can be: silk-screen light-transmitting, punching light-transmitting, laser engraving, or even because the lower skeleton 370 has been pre-opened during injection molding, when the total reflecting layer 320 is overlaid with the lower skeleton 370 by PVD, electroplating, etc., the corresponding opening can be automatically formed.

[0087] Second embodiment

[0088] As shown in FIG. 3A, the overall structure of the vehicle trim according to the second embodiment is similar to that of the first embodiment, and the same parts will not be described again. The difference is that the top surface 340 and the bottom surface 350 of the transparent skeleton 300 are both planar and form an acute angle with each other.

[0089] When the half-reflection half-transmission layer 310 and the total reflection layer 320 form an acute included angle as shown in FIG. 3A, and both the half-reflection half-transmission layer 310 and the total reflection layer 320 are planar, the optical pattern 330 emitted will present a regular depth of field similar to that shown in FIG. 3A as image D, image E, image F after multiple transmissions and reflections along different light propagation paths 440, 450, 460 between the half-reflection half-transmission layer 310 and the total reflection layer 320, i.e. a depth of field visual effect of equal included angles (between adjacent images), identical shapes and gradually diminishing brightness (the imaging principle of virtual images E' and F' is similar to that of B' and C' described above), and a stereoscopic visual reference effect as shown in FIG. 3B.

[0090] Third embodiment

[0091] As shown in FIG. 4A, the overall structure of the vehicle trim according to the third embodiment is similar to that of the first embodiment, and the same parts will not be described again. The difference lies only in that the thickness of the central region of the transparent framework 300 is smaller than that of the edge region. More specifically, one of the top surface 340 and the bottom surface 350 of the transparent framework 300 is planar, and the other is a concave curved surface, for example, in the embodiment shown in FIG. 4A, the top surface 340 of the transparent framework 300 is a concave curved surface, and the bottom surface 350 is planar; or both the top surface 340 and the bottom surface 350 of the transparent framework 300 are concave curved surfaces; or one of the top surface 340 and the bottom surface 350 of the transparent framework 300 is a concave curved surface, and the other is a convex curved surface, and the radius of curvature of the convex curved surface is greater than that of the concave curved surface, for example, in the embodiment variant shown in FIG. 4B, the top surface 340 of the transparent framework 300 is a concave curved surface, and the bottom surface 350 is a convex curved surface, and the radius of curvature of the bottom surface 350 is greater than that of the top surface 340.

[0092] When the half-reflection half-transmission layer 310 and the total reflection layer 320 are respectively laminated on the top surface 340 and the bottom surface 350 of the transparent framework 300 satisfying the structure of the present embodiment as shown in FIG. 4A, the optical pattern 330 emitted will present a regular depth of field similar to that shown in FIG. 4A as image G, image H, image I after multiple transmissions and reflections along different light propagation paths 470, 480, 490 between the half-reflection half-transmission layer 310 and the total reflection layer 320, i.e. a depth of field visual effect of gradually decreasing spacing (the spacing between image H and image I is smaller than that between image G and image H), gradually compressed shape and gradually diminishing brightness (the imaging principle of virtual images H' and I' is similar to that of B' and C' described above), and a stereoscopic visual reference effect as shown in FIG. 4C.

[0093] In other implementation variants, the transparent skeleton 300 is replaced by an upper skeleton 360 and a lower skeleton 370 as shown in FIGS. 6B and 6C. The top or bottom surface of the upper skeleton 360 is overlaid with the semi-reflective and semi-transmissive layer 310, and the top or bottom surface of the lower skeleton 370 is overlaid with the full reflective layer 320, and the surfaces of the upper skeleton 360 overlaid with the semi-reflective and semi-transmissive layer 310 and the surfaces of the lower skeleton 370 overlaid with the full reflective layer 320 are both planar or smoothly curved surfaces with continuous curvature that meet the requirements of the configuration of the present embodiment, and the surfaces of the upper skeleton 360 and the lower skeleton 370 not overlaid with the semi-reflective and semi-transmissive layer 310 or the full reflective layer 320 are not subject to special requirements. For example, in the implementation variant shown in FIG. 6B, the semi-reflective and semi-transmissive layer 310 is overlaid on the top surface of the upper skeleton 360 that forms a concave curved surface, and the full reflective layer 320 is overlaid on the bottom surface of the lower skeleton 370 that forms a planar surface, thereby forming an overall configuration between the semi-reflective and semi-transmissive layer 310 and the full reflective layer 320 in which the thickness of the central region is less than the thickness of the edge region to obtain the depth-of-field visual effect as shown in FIG. 4A. Also for example, in the implementation variant shown in FIG. 6C, the semi-reflective and semi-transmissive layer 310 is overlaid on the bottom surface of the upper skeleton 360 that forms a convex curved surface, and the full reflective layer 320 is overlaid on the bottom surface of the lower skeleton 370 that forms a planar surface, thereby forming an overall configuration between the semi-reflective and semi-transmissive layer 310 and the full reflective layer 320 in which the thickness of the central region is less than the thickness of the edge region to obtain the depth-of-field visual effect as shown in FIG. 4A.

[0094] It can be understood that the forming process, material, color, and other features and parameters of the upper skeleton 360 and the lower skeleton 370 are similar to those of the first embodiment, and thus are not described again.

[0095] Fourth Embodiment

[0096] As shown in FIG. 5A, the overall structure of the vehicle trim according to the fourth embodiment is similar to that of the first embodiment, and the same parts are not described again. The difference is that the thickness of the central region of the transparent skeleton 300 is greater than the thickness of the edge region thereof. More specifically, one of the top surface 340 and the bottom surface 350 of the transparent skeleton 300 is planar, and the other is a convex curved surface, for example, in the embodiment shown in FIG. 5A, the top surface 340 of the transparent skeleton 300 is a convex curved surface, and the bottom surface 350 is planar; or both the top surface 340 and the bottom surface 350 of the transparent skeleton 300 are convex curved surfaces; or one of the top surface 340 and the bottom surface 350 of the transparent skeleton 300 is a concave curved surface, and the other is a convex curved surface, and the radius of curvature of the concave curved surface is greater than the radius of curvature of the convex curved surface, for example, in the implementation variant shown in FIG. 5B, the top surface 340 of the transparent skeleton 300 is a convex curved surface, and the bottom surface 350 is a concave curved surface, and the radius of curvature of the bottom surface 350 is greater than the radius of curvature of the top surface 340.

[0097] In the present disclosure and the accompanying drawings, "concave surface" and "convex surface" are defined with reference to the shape of the transparent skeleton 300 itself, regardless of the position of the observer 100. That is, if the center of the top surface 340 of the transparent skeleton 300 is concave downward compared to the edge thereof, the top surface 340 is a concave surface, as shown in FIGS. 4A and 4B; if the center of the top surface 340 of the transparent skeleton 300 is convex upward compared to the edge thereof, the top surface 340 is a convex surface, as shown in FIGS. 5A and 5B; if the center of the bottom surface 350 of the transparent skeleton 300 is concave upward compared to the edge thereof, the bottom surface 350 is a concave surface, as shown in FIG. 5B; and if the center of the bottom surface 350 of the transparent skeleton 300 is convex downward compared to the edge thereof, the bottom surface 350 is a convex surface, as shown in FIG. 4B.

[0098] When the semi-reflective semi-transmissive layer 310 and the total reflective layer 320 are respectively attached to the top surface 340 and the bottom surface 350 of the transparent skeleton 300 that satisfy the configuration of the present embodiment, as shown in FIG. 5A, the emitted optical pattern 330 will present a regular depth of field similar to the images J, K, and L shown in FIG. 5A, i.e., a depth of field visual effect (the imaging principle of the virtual images K' and L' is similar to that of B' and C' described above) with gradually increasing spacing (the spacing between image K and image L is greater than that between image J and image K), gradually curved and stretched shape, and gradually decreasing brightness, and a stereoscopic visual reference effect, as shown in FIG. 5C, along different light ray propagation paths 4100, 4110, 4120 between the semi-reflective semi-transmissive layer 310 and the total reflective layer 320.

[0099] In other implementation variants, the transparent skeleton 300 is replaced by an upper skeleton 360 and a lower skeleton 370 as shown in FIGS. 6D and 6E. The top or bottom surface of the upper skeleton 360 is covered by the semi-reflective and semi-transmissive layer 310, and the top or bottom surface of the lower skeleton 370 is covered by the full reflective layer 320, and the surface of the upper skeleton 360 covered by the semi-reflective and semi-transmissive layer 310 and the surface of the lower skeleton 370 covered by the full reflective layer 320 are both planar or curved surfaces with continuous curvature that meet the requirements of the configuration of the present embodiment, and the shape of the surface of the upper skeleton 360 and the lower skeleton 370 not covered by the semi-reflective and semi-transmissive layer 310 or the full reflective layer 320 is not particularly required. For example, in the implementation variant shown in FIG. 6D, the semi-reflective and semi-transmissive layer 310 is covered on the top surface of the upper skeleton 360 forming a convex curved surface, and the full reflective layer 320 is covered on the bottom surface of the lower skeleton 370 forming a planar surface, thereby forming an overall configuration between the semi-reflective and semi-transmissive layer 310 and the full reflective layer 320 with a central region thickness greater than an edge region thickness to obtain the depth of field visual effect as shown in FIG. 5A. Also for example, in the implementation variant shown in FIG. 6E, the semi-reflective and semi-transmissive layer 310 is covered on the bottom surface of the upper skeleton 360 forming a concave curved surface, and the full reflective layer 320 is covered on the bottom surface of the lower skeleton 370 forming a planar surface, thereby forming an overall configuration between the semi-reflective and semi-transmissive layer 310 and the full reflective layer 320 with a central region thickness greater than an edge region thickness to obtain the depth of field visual effect as shown in FIG. 5A.

[0100] It can be understood that the forming process, material, color, and other features and parameters of the upper skeleton 360 and the lower skeleton 370 are similar to those of the first embodiment, and thus are not described again.

[0101] Fifth Embodiment

[0102] As shown in FIG. 7A, the overall structure of the vehicle trim according to the fifth embodiment is similar to that of the first embodiment, and the same parts are not described again, and the difference is only that the light source and the optical pattern have different configurations.

[0103] In the fifth embodiment, the light source is a side-in light source 220 arranged on the side surface of the transparent skeleton 300 to illuminate the transparent skeleton 300, which can be a PCB light plate with LED lamp beads as shown in FIG. 7A, or a light guide strip, a light guide plate, a light homogenizing film, a light homogenizing plate, a light-emitting film, or a light-emitting optical fiber, etc. that can emit light after being irradiated by the light source.

[0104] The optical pattern 330 is integrated inside the transparent skeleton 300, for example, by printing, etching, laser engraving, bubble, or insert injection molding of reflective materials or components, etc. inside the transparent skeleton 300.

[0105] As shown in FIG. 7A, the side-in light source 220 illuminates the optical pattern 330 in the transparent skeleton 300, so that the light-emitting optical pattern 330 transmits and reflects multiple times along different light ray propagation paths 4160, 4170, 4180, 4190, 4200, 4210 between the semi-reflective and semi-transmissive layer 310 and the total reflection layer 320, and will present a regular depth of field similar to the images P, Q, R, S, T, U shown in FIG. 7A, i.e. a depth of field visual effect with equal intervals between adjacent images, the same shape, and gradually decreasing brightness.

[0106] It is worth noting that, regardless of the configuration of the optical pattern 330 and the light source, as long as the optical pattern 330 is between the semi-reflective and semi-transmissive layer 310 and the total reflection layer 320, the virtual image Q is a virtual image obtained by mirror reflection of the image P through the total reflection layer 320, and at this time the brightness of the image P is greater than the brightness of the virtual image Q; the forming paths of the virtual image R and the virtual image S are: the image P and the virtual image Q are mirror reflected through the semi-reflective and semi-transmissive layer 310 to obtain the virtual image R' and the virtual image S', and the virtual image R' and the virtual image S' are mirror reflected through the total reflection layer 320 to obtain the virtual image R and the virtual image S, at this time the brightness of the virtual image R is greater than the brightness of the virtual image S, and the brightness of the virtual image R and the virtual image S is respectively lower than the brightness of the image P and the virtual image Q, and the brightness difference between the virtual image Q and the virtual image R is large, and the brightness difference between the image P and the virtual image Q and between the virtual image R and the virtual image S is small; similarly, the forming paths of the virtual image T and the virtual image U are: the image R and the virtual image S are mirror reflected through the semi-reflective and semi-transmissive layer 310 to obtain the virtual image T' and the virtual image U', and the virtual image T' and the virtual image U' are mirror reflected through the total reflection layer 320 to obtain the virtual image T and the virtual image U, at this time the brightness of the virtual image T is greater than the brightness of the virtual image U, and the brightness of the virtual image T and the virtual image U is respectively lower than the brightness of the image R and the virtual image S, and the brightness difference between the virtual image S and the virtual image T is large, and the brightness difference between the virtual image T and the virtual image U is small. Thus, a regular depth of field visual effect with different brightness differences and gradually decreasing brightness is formed visually.

[0107] In the embodiment variant shown in FIG. 7B, if a group of two or more different optical patterns 330 are arranged in an up-down interval between the semi-reflective and semi-transmissive layer 310 and the total reflection layer 320, a regular depth of field visual effect with different brightness differences and gradually decreasing brightness of the group of optical patterns 330 can be formed visually.

[0108] In the embodiment variant shown in FIG. 7C, if the optical pattern 330 between the semi-reflective semi-transmissive layer 310 and the total reflective layer 320 is arranged close to the semi-reflective semi-transmissive layer 310 and the total reflective layer 320 with a very small gap, a regular depth-of-field effect with gradually fading brightness and end-to-end connection can be visually formed. The optical pattern 330 can also be arranged in multiple, the multiple optical patterns 330 are sequentially in contact between the semi-reflective semi-transmissive layer 310 and the total reflective layer 320, and the optical patterns 330 at both ends are arranged close to the semi-reflective semi-transmissive layer 310 and the total reflective layer 320 with a very small gap, which can also visually form a regular depth-of-field effect with gradually fading brightness and end-to-end connection.

[0109] In the embodiment variant shown in FIG. 7D, the transparent framework 300 can be replaced by the upper framework 360 and the lower framework 370 similar to the embodiment of FIG. 6A, and the light-emitting optical pattern 330 will present a regular depth-of-field similar to the images V, W, X, Y, Z, AA shown in FIG. 7D after multiple transmissions and reflections along different light propagation paths 4220, 4230, 4240, 4250, 4260, 4270 between the semi-reflective semi-transmissive layer 310 and the total reflective layer 320, i.e., a depth-of-field visual effect with equal spacing, same shape and gradually fading brightness (the imaging principles of the virtual images X', Y', Z' and AA' are similar to R', S', T' and U' described above). It can be understood that in this embodiment variant, if the lower framework 370 is a non-transparent piece, the total reflective layer 320 is overlaid with the top surface of the lower framework 370, and at this time the optical pattern 330 needs to be formed in the upper framework 360.

[0110] Sixth Embodiment

[0111] As shown in FIG. 8A, the overall structure of the vehicle trim according to the sixth embodiment is similar to the first embodiment, and the same parts will not be described again. The difference is only that the light source and the optical pattern have different configurations.

[0112] In the sixth embodiment, the light source is a coherent light source 230, and the optical pattern is provided by a grating film 380 arranged on the side of the transparent framework 300, and the coherent light source 230 is located behind the grating film 380 to illuminate the grating film 380 and the transparent framework 300. The coherent light source 230 can be a laser emitter in the visible light band or other visible coherent light source. The optical pattern is designed in the grating film 380, and when a single beam of single-direction propagating coherent light passes through the grating film 380, it will continue to propagate in multiple four-directions in the form of coherent light, and at this time the coherent light will have the optical pattern, and when any one of the four-directional propagating coherent light is reflected into the human eye on a plane, the human eye can see the optical pattern based on the design of the grating film 380.

[0113] As shown in FIG. 8A, the light emitted by the coherent light source 230, after passing through the optical patterned grating film 380, imparts the optical pattern 330 on the total reflection layer 320 or the semi-reflective and semi-transmissive layer 310, so that the light of the optical pattern is transmitted and reflected multiple times between the semi-reflective and semi-transmissive layer 310 and the total reflection layer 320 along different light propagation paths 4280, 4290, 4300, and will present a regular depth of field similar to that shown in FIG. 8A as image AB, image AC, image AD, i.e., a depth of field visual effect (the imaging principles of virtual images AC' and AD' are similar to those of B' and C' described above) with equal spacing, same shape, and gradually decreasing brightness between adjacent images.

[0114] In the embodiment variant shown in FIG. 8B, the transparent framework 300 can be replaced by the upper framework 360 and the lower framework 370 similar to the embodiment of FIG. 6A, and the light of the optical pattern 330, after being transmitted and reflected multiple times between the semi-reflective and semi-transmissive layer 310 and the total reflection layer 320 along different light propagation paths 4310, 4320, 4330, will present a regular depth of field similar to that shown in FIG. 8B as image AE, image AF, image AG, i.e., a depth of field visual effect (the imaging principles of virtual images AF' and AG' are similar to those of B' and C' described above) with equal spacing, same shape, and gradually decreasing brightness between adjacent images.

[0115] Seventh Embodiment

[0116] As shown in FIG. 9A, the overall structure of the vehicle trim according to the seventh embodiment is similar to that of the first embodiment, and the same parts will not be described again. The difference is that the light source and the optical pattern have different configurations.

[0117] In the seventh embodiment, the light source is a molded-in point light source 240 integrated inside the transparent framework 300, which forms the optical pattern 330 in this embodiment. The molded-in point light source 240 can be a light-emitting light source embedded in the transparent framework 300 through a process such as insert molding.

[0118] As shown in FIG. 9A, the molded-in point light source 240 located in the transparent framework 300 serves as both the light source and the light-emitting pattern 330, and the light emitted by itself as the optical pattern 330 is transmitted and reflected multiple times between the semi-reflective and semi-transmissive layer 310 and the total reflection layer 320 along different light propagation paths 4340, 4350, 4360, 4370, 4380, 4390, and will present a regular depth of field similar to that shown in FIG. 9A as image AH, image AI, image AJ, image AK, image AL, image AM, i.e., a depth of field visual effect (the imaging principles of virtual images AJ' AK', AL' and AM' are similar to those of R', S', T' and U' described above) with equal spacing, same shape, and gradually decreasing brightness between adjacent images.

[0119] In the implementation variant shown in FIG. 9B, the transparent skeleton 300 can be replaced by an upper skeleton 360 and a lower skeleton 370 similar to the embodiment of FIG. 6A, and the in-mold point light source 240 can be embedded in the upper skeleton 360 or the lower skeleton 370 or placed between the upper skeleton 360 and the lower skeleton 370. The light emitted by the in-mold point light source 240 itself as the optical pattern 330 will exhibit the regular depth of field similar to the images AN, AO, AP, AQ, AR, and AS shown in FIG. 9B, i.e., the depth of field visual effect (the imaging principles of the virtual images AP', AQ', AR', and AS' are similar to those of R', S', T', and U' described above) with equal intervals between adjacent images, the same shape, and gradually decreasing brightness after multiple transmissions and reflections along different light ray propagation paths 4400, 4410, 4420, 4430, 4440, 4450 between the semi-transmissive and semi-reflective layer 310 and the full reflective layer 320. It can be understood that in this implementation variant, if the lower skeleton 370 is a non-transparent piece, the full reflective layer 320 is in contact with the top surface of the lower skeleton 370. In this case, the in-mold point light source 240 and the optical pattern 330 need to be formed in the upper skeleton 360 or between the upper skeleton 360 and the lower skeleton 370.

[0120] Eighth Embodiment

[0121] As shown in FIG. 10A, the overall structure of the vehicle trim according to the eighth embodiment is similar to that of the first embodiment, and the same parts will not be described again. The difference lies only in the different configurations of the light source and the optical pattern.

[0122] In the eighth embodiment, the light source is a side-in light source 220 arranged on the side surface of the transparent skeleton 300. The side-in light source 220 can be a PCB light plate with LED lamp beads as shown in FIG. 10A, or a light guide strip, a light guide plate, a light homogenizing film, a light homogenizing plate, a light-emitting film, or a light-emitting optical fiber that can emit light after being irradiated by the light source.

[0123] The optical pattern 330 is provided by an in-mold light guide strip 250 arranged at least partially in the transparent skeleton 300. More specifically, the in-mold light guide strip 250 extends from the side-in light source 220 to the inside of the transparent skeleton 300, and the optical pattern 330 is one or more light-emitting points formed on the in-mold light guide strip 250 and located in the transparent skeleton 300. The in-mold light guide strip 250 can be a common light guide strip, a soft light guide, an optical fiber, etc., and can be embedded in the transparent skeleton 300 by insert molding or two-color injection molding.

[0124] As shown in FIG. 10A, the light emitted by the side-in light source 220 is irradiated into the in-mold light guide strip 250, so that the in-mold light guide strip 250 emits light, and the light emitted by the in-mold light guide strip 250 is transmitted and reflected multiple times along different light ray propagation paths 4460, 4470, 4480, 4490, 4500, 4510 between the semi-reflective semi-transmissive layer 310 and the full reflective layer 320, and then presents a regular depth of field similar to that shown in the images AT, AU, AV, AW, AX, AY in FIG. 10A, i.e., a depth of field visual effect (the imaging principles of the virtual images AV, AW, AX, and AY are similar to those of R, S, T, and U described above) with equal intervals between adjacent images, the same shape, and gradually decreasing brightness.

[0125] In the implementation variant shown in FIG. 10B, the transparent framework 300 can be replaced by the upper framework 360 and the lower framework 370 similar to the embodiment of FIG. 6A, the in-mold light guide strip 250 can be embedded in the upper framework 360 or the lower framework 370, or placed between the upper framework 360 and the lower framework 370, and the light emitted by the in-mold light guide strip 250 is transmitted and reflected multiple times along different light ray propagation paths 4520, 4530, 4540, 4550, 4560, 4570 between the semi-reflective semi-transmissive layer 310 and the full reflective layer 320, and then presents a regular depth of field similar to that shown in the images AZ, BA, BB, BC, BD, and BE in FIG. 10B, i.e., a depth of field visual effect (the imaging principles of the virtual images BB, BC, BD, and BE are similar to those of R, S, T, and U described above) with equal intervals between adjacent images, the same shape, and gradually decreasing brightness. It can be understood that in this implementation variant, if the lower framework 370 is a non-transparent piece, the full reflective layer 320 is overlaid with the top surface of the lower framework 370, at which time the in-mold light guide strip 250 and the optical pattern 330 need to be formed in the upper framework 360 or between the upper framework 360 and the lower framework 370.

[0126] Ninth Embodiment

[0127] As shown in FIG. 11A, the overall structure of the vehicle trim part according to the ninth embodiment is similar to that of the first embodiment, and the same parts are not described again. The difference is only that the light source and the optical pattern have different configurations.

[0128] In the ninth embodiment, the light source is a conformal light panel light source 260 disposed on the bottom surface 350 of the transparent framework 300, and the conformal light panel light source 260 provides the optical pattern 330 in this embodiment. The conformal light panel light source 260 can be light rays emitted by light emitting elements on a hard or soft conformal light panel in the same shape as the profile of the bottom surface 350 of the transparent framework 300, which light rays serve as both the light source and the optical pattern 330 that undergoes multiple transmissions and reflections to form the regular depth of field visual effect. The conformal light panel is in the same shape as the profile of the bottom surface 350 of the transparent framework 300, which is combined with the bottom surface of the transparent framework 300 by structural mounting, adhesive, or insert molding, etc.

[0129] As described above, the total reflection layer 320 can be combined with the bottom surface 350 of the transparent framework 300 by spraying, silk-screen printing, film pasting, electroplating, hot stamping, or PVD process, or the bottom surface 350 of the transparent framework 300 can be configured to be optically totally reflective, or an additional part with total reflection properties can be combined with the bottom surface 350 of the transparent framework 300 to be combined with the transparent framework 300. In this embodiment, the total reflection layer 320 can also be formed on the mounting carrier of the conformal light panel light source 260 (i.e., the conformal light panel for mounting the conformal light panel light source 260) by spraying, silk-screen printing, film pasting, electroplating, hot stamping, or PVD process, etc. Since the conformal light panel is in the same shape as the profile of the bottom surface 350 of the transparent framework 300 and is combined with the bottom surface 350 of the transparent framework 300 by structural mounting, adhesive, or insert molding, etc., the total reflection function on the bottom surface 350 of the transparent framework 300 can be achieved after combination.

[0130] As shown in FIG. 11A, the conformal light panel light source 260 at the bottom of the transparent framework 300 serves as both the light source and the light emitting pattern 330, and the light emitted by itself as the optical pattern 330 undergoes multiple transmissions and reflections along different light ray propagation paths 4580, 4590, 4600 between the semi-reflective and semi-transmissive layer 310 and the total reflection layer 320, to present a regular depth of field visual effect (similar to the imaging principle of virtual images BG’ and BH’) similar to the images BF, BG, and BH shown in FIG. 11A, i.e., the depth of field visual effect with equal spacing, same shape, and gradually decreasing brightness between adjacent images.

[0131] In the embodiment variant shown in FIG. 11B, the transparent skeleton 300 can be replaced by an upper skeleton 360 and a lower skeleton 370 similar to the embodiment of FIG. 6A, the total reflection layer 320 and the contoured light panel of the contoured light panel light source 260 are covered with the top surface or the bottom surface of the lower skeleton 370, and the light emitted by the contoured light panel light source 260 itself is transmitted and reflected multiple times along different light ray propagation paths 4610, 4620, 4630 between the semi-reflective and semi-transmissive layer 310 and the total reflection layer 320, and will present a regular depth of field similar to the images BI, BJ, BK shown in FIG. 11B, i.e., a depth of field visual effect (the imaging principles of the virtual images BJ' and BK' are similar to those of B' and C) with equal spacing, identical shape and gradually decreasing brightness between adjacent images. It can be understood that in this embodiment variant, if the lower skeleton 370 is a non-transparent piece, the total reflection layer 320 and the contoured light panel of the contoured light panel light source 260 are covered with the top surface of the lower skeleton 370.

[0132] Tenth embodiment

[0133] As shown in FIG. 12A, the overall structure of the vehicle trim according to the tenth embodiment is similar to that of the first embodiment, and the same parts will not be described again. The difference is that the light source and the optical pattern have different configurations, and the transparent skeleton 300 is divided into a light-emitting area R1 and a non-light-emitting area R2, the light-emitting area R1 is defined as an area that needs to be visible in function, and the non-light-emitting area R2 is defined as an area that is not visible in function, which can be shielded by physical objects, paint spraying, film pasting, silk printing and the like to achieve the effect of being visually invisible.

[0134] In the tenth embodiment, the light-reflecting optical pattern 330 is formed on the bottom surface 350 or the top surface 340 of the transparent skeleton 300, and the light source is a contoured light panel light source 260 arranged on the bottom surface 350 of the transparent skeleton 300, and the contoured light panel light source 260 is arranged in the non-light-emitting area R2.

[0135] The contoured light panel light source 260 can be light emitted by a light-emitting element on a hard or soft contoured light panel having the same shape as the profile of the bottom surface 350 of the transparent skeleton 300. Since the contoured light panel light source 260 is arranged in the non-light-emitting area R2, the light only serves as a light source. The contoured light panel has the same shape as the profile of the bottom surface 350 of the transparent skeleton 300, and is covered with the bottom surface 350 of the transparent skeleton 300 by structural mounting, adhesive, or insert molding.

[0136] As described above, the total reflection layer 320 can be formed on the bottom surface 350 of the transparent skeleton 300 by spraying, silk printing, film pasting, electroplating, hot stamping or PVD process, or the bottom surface 350 of the transparent skeleton 300 can be configured to be totally reflective, or the bottom surface 350 of the transparent skeleton 300 can be pasted with an additional part having total reflection property. In this embodiment, the total reflection layer 320 can also be formed on the mounting carrier of the contoured lamp panel light source 260 (i.e. the contoured lamp panel for mounting the contoured lamp panel light source 260) by spraying, silk printing, film pasting, electroplating, hot stamping or PVD process. Since the shape of the contoured lamp panel is the same as the profile of the bottom surface 350 of the transparent skeleton 300 and the contoured lamp panel is pasted with the bottom surface 350 of the transparent skeleton 300 by structural mounting, adhesive or insert injection molding, the total reflection function of the bottom surface 350 of the transparent skeleton 300 can be realized after pasting.

[0137] The optical pattern 330 can be a 3D feature (which can not be specially treated or partially polished, textured, etc.) in the local concave or protruding part of the bottom surface 350 or the top surface 340 of the transparent skeleton 300, or a graphic feature on the bottom surface 350 or the top surface 340 of the transparent skeleton 300, or the surface pasted with the total reflection layer 320 or the semi-reflective and semi-transmissive layer 310, respectively. The optical pattern 330 can even be a part with reflective 3D or 2D features on an additional part pasted on the bottom surface 350 or the top surface 340 of the transparent skeleton 300. The optical pattern 330 only needs to present different brightness effects when light is shone on the total reflection layer 320 or the semi-reflective and semi-transmissive layer 310, and the light can be reflected and transmitted multiple times between the semi-reflective and semi-transmissive layer 310 and the total reflection layer 320 to form a regular depth of field visual effect. The type of the optical pattern 330 is not limited in the present disclosure.

[0138] As shown in FIG. 12A, the light emitted by the contoured lamp panel light source 260 can propagate in the transparent skeleton 300. When the light emitted by the contoured lamp panel light source 260 illuminates the optical pattern 330, the patterned light rays will be transmitted and reflected multiple times along different light propagation paths 4640, 4650, 4660 between the semi-reflective and semi-transmissive layer 310 and the total reflection layer 320, presenting a regular depth of field visual effect (the imaging principle of the virtual images BM’ and BN’ is similar to that of B’ and C’ described above) similar to the images BL, BM, BN shown in FIG. 12A, i.e. equal spacing, same shape and gradually decreasing brightness between adjacent images.

[0139] In the embodiment variant shown in FIG. 12B, the transparent skeleton 300 can be replaced by an upper skeleton 360 and a lower skeleton 370 similar to the embodiment of FIG. 6A, the total reflection layer 320 and the contoured lamp panel of the contoured lamp panel light source 260 are covered with the top surface or the bottom surface of the lower skeleton 370, and the optical pattern 330 can be formed on the top surface or the bottom surface of the upper skeleton 360 or the top surface or the bottom surface of the lower skeleton 370. When the light emitted by the contoured lamp panel light source 260 illuminates the optical pattern 330, the patterned light rays will present a regular depth of field similar to the images BO, BP, and BQ shown in FIG. 12B, i.e., a depth of field visual effect (the imaging principles of the virtual images BP' and BQ' are similar to those of B' and C' described above) with equal intervals between adjacent images, the same shape, and gradually decreasing brightness, after multiple transmissions and reflections along different light propagation paths 4670, 4680, and 4690 between the semi-reflective and semi-transmissive layer 310 and the total reflection layer 320. It can be understood that in this embodiment variant, if the lower skeleton 370 is a non-transparent piece, the total reflection layer 320 and the contoured lamp panel of the contoured lamp panel light source 260 are covered with the top surface of the lower skeleton 370, and the optical pattern 330 can be formed on the top surface of the lower skeleton 370.

[0140] Eleventh Embodiment

[0141] As shown in FIG. 13A, the overall structure of the vehicle trim according to the tenth embodiment is similar to that of the first embodiment, and the same parts will not be described again. The difference is only that the light source and the optical pattern have different configurations, and the transparent skeleton 300 is divided into a light-emitting area R1 and a non-light-emitting area R2, the light-emitting area R1 is defined as an area that needs to be visible in function, and the non-light-emitting area R2 is defined as an area that is not visible in function, which can be shielded by physical objects, paint spraying, film pasting, silk printing, and similar means to achieve a visually invisible effect.

[0142] In the eleventh embodiment, the light-reflective optical pattern 330 is formed on the bottom surface 350 or the top surface 340 of the transparent skeleton 300, and the light source is a contoured lamp panel light source 260 arranged on the top surface 340 of the transparent skeleton 300, and the contoured lamp panel light source 260 is arranged in the non-light-emitting area R2.

[0143] The contoured lamp panel light source 260 can be light emitted by light-emitting elements on a hard or soft contoured lamp panel with the same shape as the profile of the top surface 340 of the transparent skeleton 300. Since the contoured lamp panel light source 260 is arranged in the non-light-emitting area R2, the light only serves as a light source. The shape of the contoured lamp panel is the same as the profile of the top surface 340 of the transparent skeleton 300, which is covered with the top surface 340 of the transparent skeleton 300 by structural mounting, adhesive, or insert molding.

[0144] As described above, the semi-reflective and semi-transmissive layer 310 can be attached to the top surface 340 of the transparent skeleton 300 by pasting a semi-reflective and semi-transmissive film, spraying or brushing a semi-reflective and semi-transmissive coating, PVD, or by using an additional part with semi-reflective and semi-transmissive properties to cover the top surface 340 of the transparent skeleton 300. In this embodiment, the semi-reflective and semi-transmissive layer 310 can also be formed on the mounting carrier of the contoured light panel light source 260 (i.e., the contoured light panel for mounting the contoured light panel light source 260) by painting, silk printing, pasting a film, electroplating, hot stamping, or PVD, etc. Since the shape of the contoured light panel is the same as the profile of the top surface 340 of the transparent skeleton 300 and is attached to the top surface 340 of the transparent skeleton 300 by structural mounting, adhesive, or insert molding, etc., the semi-reflective and semi-transmissive function on the top surface 340 of the transparent skeleton 300 can be achieved after attachment.

[0145] The optical pattern 330 can be a 3D feature (which can not be specially treated or partially polished, textured, etc.) located in a local concave or protrusion on the bottom surface 350 or the top surface 340 of the transparent skeleton 300, or a graphic feature attached to the bottom surface 350 or the top surface 340 of the transparent skeleton 300, or the surface of the full reflective layer 320 or the semi-reflective and semi-transmissive layer 310 attached to the bottom surface 350 or the top surface 340 of the transparent skeleton 300, respectively. The optical pattern 330 can even be a part with a 3D or 2D feature on an additional part to cover the bottom surface 350 or the top surface 340 of the transparent skeleton 300. The optical pattern 330 only needs to be able to present a different brightness effect when light is shone on the full reflective layer 320 or the semi-reflective and semi-transmissive layer 310, i.e., to form a regular depth of field visual effect through multiple reflections and transmissions between the semi-reflective and semi-transmissive layer 310 and the full reflective layer 320. The present disclosure does not limit the type of optical pattern 330.

[0146] As shown in FIG. 13A, the light emitted by the contoured light panel light source 260 can propagate within the transparent skeleton 300. When the light emitted by the contoured light panel light source 260 illuminates the optical pattern 330, the patterned light rays will undergo multiple transmissions and reflections along different light propagation paths 4700, 4710, 4720 between the semi-reflective and semi-transmissive layer 310 and the full reflective layer 320, presenting a regular depth of field visual effect (similar to the images BR, BS, BT shown in FIG. 13A) with equal spacing, identical shape, and gradually decreasing brightness between adjacent images (the imaging principles of the virtual images BS’ and BT’ are similar to those of B’ and C’ described above).

[0147] In the implementation variant shown in FIG. 13B, the transparent skeleton 300 can be replaced by an upper skeleton 360 and a lower skeleton 370 similar to the embodiment of FIG. 6A, the contoured light board and the contoured light board light source 260 of the semi-transflective layer 310 are covered with the top surface or the bottom surface of the upper skeleton 360, and the optical pattern 330 can be formed on the top surface or the bottom surface of the upper skeleton 360 or the top surface or the bottom surface of the lower skeleton 370. When the light emitted by the contoured light board light source 260 illuminates the optical pattern 330, the patterned light rays will present a regular depth of field similar to the images BU, BV, and BW shown in FIG. 13B, i.e., the depth of field visual effect (the imaging principles of the virtual images BV' and BW' are similar to the above B' and C') with equal spacing, same shape, and gradually decreasing brightness between adjacent images, after multiple transmissions and reflections along different light propagation paths 4730, 4740, 4750 between the semi-transflective layer 310 and the total reflection layer 320. It can be understood that in this implementation variant, if the lower skeleton 370 is a non-transparent piece, the total reflection layer 320 is covered with the top surface of the lower skeleton 370, and the optical pattern 330 can be formed on the top surface of the lower skeleton 370.

[0148] Twelfth Embodiment

[0149] As shown in FIG. 14A, the overall structure of the vehicle trim according to the twelfth embodiment is similar to the first embodiment, and the same parts will not be described again. The difference is only that the light source and the optical pattern have different configurations, and the transparent skeleton 300 is formed by an injection molding process and the injection molding material is mixed with tiny particles.

[0150] In the twelfth embodiment, the light source is a side-in light source 220 arranged on the side surface of the transparent skeleton 300. The side-in light source 220 can be a PCB light board with LED lamp beads as shown in FIG. 10A, or a light guide strip, a light guide plate, a light homogenizing film, a light homogenizing plate, a light-emitting film, or a light-emitting optical fiber, etc., which can emit light after being irradiated by the light source.

[0151] The optical pattern 330 is provided by the patterned light-transmissive layer 390 arranged on the side of the transparent skeleton 300. More specifically, the patterned light-transmissive layer 390 is arranged between the edge-lit light source 220 and the transparent skeleton 300, and the patterned light-transmissive layer 390 has patterned light-transmissive regions and non-light-transmissive regions, so that the light emitted by the edge-lit light source 220 is provided with a specific light pattern after passing through the patterned light-transmissive layer 390. Since the injection-molded material of the transparent skeleton 300 is mixed with tiny particles, the tiny particles are uniformly distributed in the entire transparent skeleton 300 during the injection molding of the transparent skeleton 300 and are basically invisible to the naked eye, but when the light with the specific light pattern is emitted into the transparent skeleton 300 with the tiny particles from the edge-lit light source 220 through the patterned light-transmissive layer 390, the light is scattered after colliding with the tiny particles, so that the specific light pattern can be seen by the human eye in the transparent skeleton 300, and any light-emitting point on the light rays of the specific light pattern constitutes the optical pattern 330.

[0152] The patterned light-transmissive layer 390 can be a pure transparent plate, and the patterned light-transmissive regions and non-light-transmissive regions with a specific pattern can be formed on the transparent plate by means of film pasting (the light-transmissive and non-light-transmissive regions on the film are realized by printing, silk printing, or direct punching), shielding paint spraying, silk printing, electroplating, PVD, hot stamping, shielding by another part, etc.; or the patterned light-transmissive layer 390 can be a non-transparent plate, and the patterned light-transmissive regions and non-light-transmissive regions with a specific pattern can be formed on the non-transparent plate by punching, laser engraving, etc.; or the patterned light-transmissive layer 390 can also be a film, and the patterned light-transmissive regions and non-light-transmissive regions with a specific pattern can be formed on the film by film pasting, paint spraying, silk printing, electroplating, PVD, hot stamping, shielding by another part, etc., and the present disclosure does not limit the type of the patterned light-transmissive layer 390.

[0153] As shown in FIG. 14A, since the injection-molded material of the transparent skeleton 300 is mixed with tiny particles, the light of the optical pattern 330 formed by illuminating the tiny particles will present a regular depth of field (the depth of field visual effect (virtual images BZ', CA', CB', and CC') with equal intervals between adjacent images, the same shape, and gradually disappearing brightness) similar to that shown in images BX, BY, BZ, CA, CB, and CC in FIG. 14A after multiple transmissions and reflections along different light ray propagation paths 4760, 4770, 4780, 4790, 4800, 4810 between the semi-reflective and semi-transmissive layer 310 and the full reflective layer 320.

[0154] In the embodiment variant shown in FIG. 14B, the transparent framework 300 can be replaced by an upper framework 360 and a lower framework 370, both of which are made of injection-molded plastic mixed with tiny particles, similar to the embodiment of FIG. 6A. In this case, the light of the optical pattern 330 can enter either the upper framework 360 or the lower framework 370, and after multiple transmissions and reflections along different light ray propagation paths 4820, 4830, 4840, 4850, 4860, 4870 between the semi-reflective-transmissive layer 310 and the full-reflective layer 320, the light will present a regular depth of field similar to the images CD, CE, CF, CG, CH, CI shown in FIG. 14B, i.e., a depth of field visual effect (the imaging principles of the virtual images CF', CG', CH', and CI' are similar to R', S', T', and U' described above) with equal intervals between adjacent images, identical shapes, and gradually decreasing brightness. It can be understood that in this embodiment variant, if the lower framework 370 is non-transparent, the full-reflective layer 320 is in contact with the top surface of the lower framework 370, and in this case, the light of the optical pattern 330 must enter the upper framework 360.

[0155] Thirteenth Embodiment

[0156] As shown in FIG. 15A, the overall structure of the vehicle trim according to the thirteenth embodiment is similar to that of the first embodiment, and the same parts will not be described again. The difference is that the light source and the optical pattern have different configurations.

[0157] In the thirteenth embodiment, the light source is a side-in light source 220 arranged on the side surface of the transparent framework 300. The side-in light source 220 can be a PCB light plate with LED lamp beads as shown in FIG. 10A, or a light guide strip, a light guide plate, a light homogenizing film, a light homogenizing plate, a light-emitting film, or a light-emitting optical fiber that can emit light after being irradiated by the light source.

[0158] The optical pattern 330 is provided by a pattern light-transmissive layer 390 arranged on the side surface of the transparent framework 300. More specifically, the pattern light-transmissive layer 390 is arranged between the side-in light source 220 and the transparent framework 300. The patterned areas on the pattern light-transmissive layer 390 are light-transmissive, and the non-patterned areas are not light-transmissive, thereby ensuring that the light emitted by the side-in light source 220 has a specific light pattern after passing through the pattern light-transmissive layer 390. When this light with a special light pattern enters the transparent framework 300, it is irradiated on the full-reflective layer 320 or the semi-reflective-transmissive layer 310 to form the optical pattern 330.

[0159] The patterned light-transmissive layer 390 can be a piece of pure transparent plate, on which the light-transmissive area and non-light-transmissive area with specific pattern are formed by pasting film (light-transmissive and non-light-transmissive on the film are realized by printing, silk printing or direct punching, etc.), shielding spray paint, silk printing, electroplating, PVD, hot stamping, shielding with another part, etc.; or can be a piece of opaque plate, on which the light-transmissive hole is formed by punching, laser engraving, etc. to realize the light-transmissive area and non-light-transmissive area with specific pattern; or can even be a piece of film, on which the light-transmissive area and non-light-transmissive area with specific pattern are formed by pasting film, spray paint, silk printing, electroplating, hot stamping, shielding with another part, etc. The type of the patterned light-transmissive layer 390 is not limited in the present disclosure.

[0160] As shown in FIG. 15A, when the light with special light type is irradiated on the total reflection layer 320 or the semi-transmission and semi-reflection layer 310 to form the optical pattern 330, the light of the optical pattern 330 will be transmitted and reflected for multiple times along different light propagation paths 4880, 4890, 4900 between the semi-transmission and semi-reflection layer 310 and the total reflection layer 320, and will present regular depth of field similar to the images CJ, CK, CL shown in FIG. 15A, i.e. the depth of field visual effect (the imaging principle of the virtual images CK' and CL' is similar to the above B' and C) with equal interval, same shape and gradually disappearing brightness between adjacent images.

[0161] In the embodiment variant shown in FIG. 15B, the transparent framework 300 can be replaced by the upper framework 360 and the lower framework 370 similar to the embodiment of FIG. 6A, when the light with special light type is irradiated on the total reflection layer 320 or the semi-transmission and semi-reflection layer 310 to form the optical pattern 330, the light of the optical pattern 330 will be transmitted and reflected for multiple times along different light propagation paths 4910, 4920, 4930 between the semi-transmission and semi-reflection layer 310 and the total reflection layer 320, and will present regular depth of field similar to the images CM, CN, CO shown in FIG. 15B, i.e. the depth of field visual effect (the imaging principle of the virtual images CN' and CO' is similar to the above B' and C) with equal interval, same shape and gradually disappearing brightness between adjacent images.

[0162] Figures 16A-16C show one physical application of vehicle trim according to the present disclosure, i.e., a vehicle door regular depth of field light trim assembly 500, which mainly consists of screws 540, door trim panel 530, light module housing 520, direct type light source 210, light homogenizing plate 510, and transparent skeleton 300. The semi-reflective and semi-transmissive layer 310 is a film, which is attached to the top surface 340 (i.e., the surface away from the direct type light source 210 in Figure 16B) of the transparent skeleton 300 by, for example, IML (Insert Molding) process. The full reflective layer 320 is attached to the bottom surface 350 (i.e., the surface close to the direct type light source 210 in Figure 16B) of the transparent skeleton 300 by, for example, PVD process. The partially transparent optical pattern 330 is engraved on the full reflective layer 320 by, for example, laser engraving process. The direct type light source 210 is connected to the light module housing 520 by, for example, adhesive. The light homogenizing plate 510 is fixed on the light module housing 520 by, for example, clamping. The transparent skeleton 300 with the semi-reflective and semi-transmissive layer 310 and the full reflective layer 320 is fixed on the light module housing 520 by, for example, clamping. Finally, the light module housing 520 with the direct type light source 210, the light homogenizing plate 510, and the transparent skeleton 300 is fixed to the door trim panel 530 by the screws 540, and the vehicle door regular depth of field light trim assembly 500 is finally formed.

[0163] In the vehicle door regular depth of field light trim assembly 500, the light emitted by the direct type light source 210 is optically mixed and homogenized by the light homogenizing plate 510, and the light after the mixing and homogenization is transmitted through the partially transparent optical pattern 330 into the space between the semi-reflective and semi-transmissive layer 310 and the full reflective layer 320. The light with the optical pattern 330 is transmitted and reflected multiple times between the semi-reflective and semi-transmissive layer 310 and the full reflective layer 320, and finally presents a regular depth of field light effect. The specific optical path can be referred to Figure 2A. As shown in Figure 16C, since the semi-reflective and semi-transmissive layer 310 and the full reflective layer 320 are smooth and parallel to each other, the light effect presented is a depth of field visual effect with equal spacing, same shape, and gradually decreasing brightness between adjacent images. The specific three-dimensional visual effect can be referred to Figure 2B.

[0164] In addition, as described above, in various embodiments, the optical pattern 330 is irradiated by the light of the light sources 210, 220, 230, 240, 250, 260, and the irradiated light of the optical pattern 330 is reflected and transmitted multiple times between the semi-reflective and semi-transmissive layer 310 and the full reflective layer 320, so that the image of the optical pattern 330 in the multiple reflection and transmission attenuation optical transmission path can be observed at the same observation position, forming a variety of regularly arranged depth-of-field visual effects. At the same time, the multiple LEDs or other light units constituting the light sources in the light sources 210, 220, 230, 240, 250, 260 can be programmed by a control program, and the light sources 210, 220, 230, 240, 250, 260 can be controlled to remain overall constant or overall bright and dark changes or overall color changes in a set manner, so as to form an overall static or overall dynamic depth-of-field light effect; or the multiple LEDs or other light units constituting the light sources in the light sources 210, 220, 230, 240, 250, 260 can be programmed by a control program, and the light sources can be controlled to make local bright and dark changes or color changes in a set manner, so as to realize a local dynamic depth-of-field light effect.
