Description

Technical Field

[0001] The utility model relates to the technical field of vehicle parts. More specifically, the utility model relates to a vehicle trim piece. Background Art

[0002] The common depth-of-field lighting effect in the current market realizes the multi-layer reflection and transmission of images or light between two film layers by means of a semi-reflective and semi-transmissive film and a total reflection film, so as to form a depth-of-field effect. Specifically, a pattern is arranged between the two film layers, and the light rays emitted by a light source are reflected and diffracted in all directions after irradiating the pattern. The light rays reach the total reflection film below, and the whole light path undergoes total reflection. The light rays reach the semi-reflective and semi-transmissive film upwards, and a part of the light is transmitted through the semi-reflective and semi-transmissive film and is seen, and the other part of the light is reflected downwards again to reach the total reflection film below for total reflection. In this way, the semi-transmission and semi-reflection and total reflection are carried out N times, so that the optical pattern observed by a human eye at an observation position has an effect of overlapping shadow depth of field (i.e., fading layer by layer).

[0003] When both the total reflection film and the semi-reflective and semi-transmissive film are plane or smooth curved surfaces, the overlapping shadows observed by a human eye are regularly arranged. For example, they are spaced at equal intervals in circles, and gradually fade in circles, that is, fade out. 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 trim pieces to increase the aesthetic degree, it is necessary to further analyze and study various rules of this lighting effect and the structural levels, relationship parameters, etc. corresponding to these rules.

Detailed Embodiments

[0067] The implementation and use of the specific embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are only exemplary illustrations of the specific ways of implementing and using the present utility model, rather than limiting the scope of the present utility model.

[0068] As Figure 1A shown, the vehicle trim according to the present utility model can be installed on the exterior of a vehicle, and it can be specifically applied to a front bumper FB including a grille, a rear bumper RB, an exterior roof RF, a trim strip RP, a fender FD, a tailgate TG, a side door SD, or a side panel SB, etc. As Figures 1B to 1DAs shown, the vehicle trim according to the present utility model can also be installed inside the vehicle, and can be specifically applied to the instrument panel IP, the front and rear door DPs, or the center console CS. It can also be applied to the ceiling CE inside the vehicle to provide, for example, a starry sky ceiling, or to the headrest HR, the seat armrest SA, or the rear side of the seat SK, etc.

[0069] First Embodiment

[0070] As Figure 2A shown, the vehicle trim according to the first embodiment includes a direct - down light source 210, a transparent skeleton 300, a semi - reflective and semi - transmissive layer 310, a total reflection layer 320, and an optical pattern 330. Among them, the top surface 340 and the bottom surface 350 of the transparent skeleton 300 are two parallel planes. The semi - reflective and semi - transmissive layer 310 is laminated on the top surface 340 of the transparent skeleton 300, the total reflection layer 320 is laminated on the bottom surface 350 of the transparent skeleton 300, the optical pattern 330 is a light - transmitting hollow structure formed on the total reflection layer 320, and the direct - down 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 skeleton 300.

[0071] The present utility model utilizes the optical total reflection mechanism of the total reflection layer 320 and the mechanism of partial light reflection and partial light transmission of the semi - reflective and semi - transmissive layer 310. After the designed optical pattern 330 is illuminated by the direct - down light source 210, the patterned light generated by it propagates between the semi - reflective and semi - transmissive layer 310 and the total reflection layer 320. When the light of the optical pattern 330 encounters the semi - reflective and semi - transmissive layer 310 during propagation, a partial transmission and partial reflection effect will occur. And due to the partial light transmission and the energy loss during reflection, the light reflected back by the optical pattern 330 when encountering the semi - reflective and semi - transmissive layer 310 undergoes a brightness attenuation. When the light of the optical pattern 330 encounters the total reflection layer 320 during propagation, a total reflection effect will occur. And because it is an optical total reflection, in theory, the brightness of the reflected light should be the same as that of the light before reflection. However, due to the manufacturing reasons of the actual reflection layer, the brightness of the reflected light will have a small brightness attenuation. Thus, the light 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 in which multiple images are regularly arranged in sequence and the brightness gradually fades.

[0072] In the first embodiment, when the light of the direct - type light source 210 irradiates towards the bottom surface 350 of the transparent framework 300, since the optical pattern 330 on the total - reflection layer 320 is light - transmissive, the light emitted by the direct - type light source 210 is illuminated after passing through the optical pattern 330. Since then, the illuminated optical pattern 330 propagates between the semi - reflective and semi - transmissive layer 310 and the total - reflection layer 320. It can be seen that when the propagated light propagates along the light - transmission path 410, it is directly seen by the observer 100 after passing through the semi - reflective and semi - transmissive layer 310, that is, the luminous image A in the figure. The light propagating along the light - transmission path 420 is reflected once at the semi - reflective and semi - transmissive layer 310 and reflected once at the total - reflection layer 320, and finally is seen by the observer 100 after passing through the semi - reflective and semi - transmissive layer 310 by transmission. Since the light seen by the observer 100 is the reflected light between the semi - reflective and semi - transmissive layer 310 and the total - reflection layer 320, the image observed by the eyeball of the observer 100 at this time is a virtual image B. The imaging path of the virtual image B is as follows: the luminous image A undergoes specular reflection through the semi - reflective and semi - transmissive layer 310 to obtain the virtual image B', and the virtual image B' undergoes specular reflection through the total - reflection layer 320 again to obtain the virtual image B. Similarly, the light propagating along the light - transmission path 430 is reflected twice at the semi - reflective and semi - transmissive layer 310 and reflected twice at the total - reflection layer 320, and finally is seen by the observer 100 after passing through the semi - reflective and semi - transmissive layer 310 by transmission. Similarly, since the light seen by the observer 100 is the reflected light between the semi - reflective and semi - transmissive layer 310 and the total - reflection layer 320, the image observed by the eyeball of the observer 100 at this time is a virtual image C. The imaging path of the virtual image C is as follows: the luminous pattern A undergoes specular reflection through the semi - reflective and semi - transmissive layer 310 to obtain the virtual image B', the virtual image B' undergoes specular reflection through the total - reflection layer 320 to obtain the virtual image B, the virtual image B undergoes specular reflection through the semi - reflective and semi - transmissive layer 310 to obtain the virtual image C', and the virtual image C' undergoes specular reflection through the total - reflection layer 320 to obtain the virtual image C. Thus, what the observer 100 finally sees is the regular depth - of - field effect with gradually diminishing brightness of images A, B, C...

[0073] When the semi - reflective and semi - transmissive layer 310 and the total - reflection layer 320 are in a parallel relationship as shown in Figure 2A and the semi - reflective and semi - transmissive layer 310 and the total - reflection layer 320 are planes or smooth surfaces with continuous curvature, after the illuminated optical pattern 330 undergoes multiple transmissions and reflections between the semi - reflective and semi - transmissive layer 310 and the total - reflection layer 320, it will present a regular depth - of - field similar to that shown in Figure 2A images A, B, and C in - that is, the depth - of - field visual effect with equal spacing (between adjacent images), the same shape, and gradually diminishing brightness. The stereoscopic vision reference effect is as shown in Figure 2B shown.

[0074] The direct - type light source 210 can be a matrix - type LED PCB light board, or a light guide bar, a light guide plate, a light - homogenizing film, a light - homogenizing plate, a light - emitting thin film, or a light - emitting optical fiber, etc. that can emit light after being irradiated by a 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.

[0075] The transparent skeleton 300 is a single piece formed by thick - wall injection molding (usually with a wall thickness of 1 mm - 11 mm). Its materials include, but are not limited to, transparent injection - molding materials such as PC (polycarbonate) and PMMA (polymethyl methacrylate). Its color can be colorless transparent or colored transparent.

[0076] The semi - reflective and semi - transmissive layer 310 can be laminated on the top surface 340 of the transparent skeleton 300 by pasting a semi - reflective and semi - transmissive film, spraying / coating a semi - reflective and semi - transmissive coating, PVD (physical vapor deposition), or fitting a separate part with semi - reflective and semi - transmissive properties to the top surface 340 of the transparent skeleton 300.

[0077] The total - reflection layer 320 can be laminated with the bottom surface 350 of the transparent skeleton 300 by painting, silk - screening, film - sticking, electroplating, hot stamping, or PVD process. The bottom surface 350 of the transparent skeleton 300 can also be constructed to have optical total - reflection, or it can be laminated on the bottom surface 350 of the transparent skeleton 300 by fitting a separate part with total - reflection properties to the bottom surface 350 of the transparent skeleton 300.

[0078] The optical pattern 330 is achieved by engraving and piercing, punching, local masking + total - reflection surface treatment (assuming the total - reflection surface substrate is pure transparent or semi - transparent, and performing masking + total - reflection surface treatment on it. The masked area is transmissive because it is not subjected to total - reflection surface treatment) or printing dot - shaped, line - shaped, or small - surface patterns that can be directly - type transmissive on the total - reflection layer 320 laminated on the bottom surface 350 of the transparent skeleton 300.

[0079] 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 Figure 6A The top surface or bottom surface of the upper skeleton 360 is laminated with the semi - reflective and semi - transmissive layer 310, and the top surface or bottom surface of the lower skeleton 370 is laminated with the total - reflection layer 320. Both the surface of the upper skeleton 360 laminated with the semi - reflective and semi - transmissive layer 310 and the surface of the lower skeleton 370 laminated with the total - reflection layer 320 are flat or smooth curved surfaces with continuous curvature. The combination of the upper skeleton 360 and the lower skeleton 370 has the same function in the present utility model as the above - mentioned transparent skeleton 300, facilitating adaptation to requirements such as weight, space layout, and cost in different usage scenarios.

[0080] When the semi - reflective and semi - transmissive layer 310 and the total - reflection layer 320 are as shown in Figure 6AWhen the parallel relationship shown is such that the semi-transmissive semi-reflective layer 310 and the total reflection layer 320 are planes or smooth surfaces with continuous curvature, after the luminous optical pattern 330 undergoes multiple transmissions and reflections between the semi-transmissive semi-reflective layer 310 and the total reflection layer 320 along different light propagation paths 4130, 4140, 4150, it will present a regular depth of field similar to that shown in Figure 6A the images M, N, and O in - that is, a depth of field visual effect with equal spacing (between adjacent images), the same shape, and gradually diminishing brightness (the imaging principles of the virtual images N' and O' are similar to those of B' and C' above).

[0081] The upper frame 360 and the lower frame 370 are formed by ordinary injection molding (usually with a wall thickness of 1 mm - 11 mm). The material can be transparent injection molding materials including but not limited to PC, PMMA, etc. The color of the upper frame 360 can be colorless transparent or colored transparent, and the color of the lower frame 370 can be colorless transparent, colored transparent, colorless semi-transparent, or colored semi-transparent.

[0082] In this variant, the lower frame 370 can also be a non-transparent part, and its color can be any non-transparent color. In this case, the total reflection layer 320 is laminated to the top surface of the lower frame 370. At this time, the optical pattern 330 can be achieved by making openings on the assembly after the lower frame 370 and the total reflection layer 320 are laminated. The means of making the openings can be directly punching or laser opening on the assembly after the lower frame 370 and the total reflection layer 320 are laminated, or the lower frame 370 can be opened by mold injection when injecting the lower frame 370, and the total reflection layer 320 is also made to be light-transmissive at the corresponding positions and laminated to the lower frame 370. At this time, the light-transmissive treatment of the total reflection layer 320 can be: such as screen printing for light transmission, punching for light transmission, laser engraving, or even when the lower frame 370 has been opened during injection molding, when the total reflection layer 320 and the lower frame 370 are laminated by processes such as PVD, electroplating, etc., openings at the corresponding positions can be automatically formed.

[0083] Second Embodiment

[0084] As Figure 3A shown, 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 repeatedly. The difference is only that the top surface 340 and the bottom surface 350 of the transparent frame 300 are both planes and form an acute angle with each other.

[0085] When the semi-transmissive semi-reflective layer 310 and the total reflection layer 320 form an acute angle as Figure 3A shown, and both the semi-transmissive semi-reflective layer 310 and the total reflection layer 320 are planes, after the luminous optical pattern 330 undergoes multiple transmissions and reflections between the semi-transmissive semi-reflective layer 310 and the total reflection layer 320 along different light propagation paths 440, 450, 460, it will present a similarFigure 3A The regular depth of field shown in the middle images D, E, and F - that is, the depth-of-field visual effect with equal angles (between adjacent images), the same shape, and gradually diminishing brightness (the imaging principles of the virtual images E' and F' are similar to those of B' and C' above), and the stereoscopic vision reference effect is as Figure 3B shown.

[0086] Third Embodiment

[0087] As Figure 4A shown, 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 repeatedly. The difference is only that the thickness of the central region of the transparent skeleton 300 is less than the thickness of its edge region. More specifically, one of the top surface 340 and the bottom surface 350 of the transparent skeleton 300 is a plane, and the other is a concave curved surface. For example, in the Figure 4A shown embodiment, the top surface 340 of the transparent skeleton 300 is a concave curved surface, and the bottom surface 350 is a plane; or, both the top surface 340 and the bottom surface 350 of the transparent skeleton 300 are concave 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 convex curved surface is greater than the radius of curvature of the concave curved surface. For example, in the Figure 4B shown implementation variant, the top surface 340 of the transparent skeleton 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 the radius of curvature of the top surface 340.

[0088] When the semi-reflective semi-transmissive layer 310 and the total reflection layer 320 are respectively laminated on the top surface 340 and the bottom surface 350 of the transparent skeleton 300 that meet the structure of this embodiment as Figure 4A shown, after the luminous optical pattern 330 undergoes multiple transmissions and reflections along different light propagation paths 470, 480, 490 between the semi-reflective semi-transmissive layer 310 and the total reflection layer 320, it will present a regular depth of field similar to that shown in the images G, H, and I in Figure 4A - that is, the distance (the distance between image H and image I is less than the distance between image G and image H) gradually decreases, the shape gradually bends and compresses, and the depth-of-field visual effect with gradually diminishing brightness (the imaging principles of the virtual images H' and I' are similar to those of B' and C' above), and the stereoscopic vision reference effect is as Figure 4C shown.

[0089] In some other implementation variants, the transparent skeleton 300 is composed of as Figure 6B and Figure 6CIt is replaced by the upper frame 360 and the lower frame 370 shown. The top surface or the bottom surface of the upper frame 360 is laminated with the semi-transmissive semi-reflective layer 310, and the top surface or the bottom surface of the lower frame 370 is laminated with the total reflection layer 320. Moreover, the surface of the upper frame 360 laminated with the semi-transmissive semi-reflective layer 310 and the surface of the lower frame 370 laminated with the total reflection layer 320 are both planes or smooth surfaces with continuous curvature that meet the structural requirements of this embodiment. There are no special requirements for the shapes of the surfaces of the upper frame 360 and the lower frame 370 that are not laminated with the semi-transmissive semi-reflective layer 310 or the total reflection layer 320. For example, in Figure 6B the shown implementation variant, the semi-transmissive semi-reflective layer 310 is laminated on the top surface of the upper frame 360 that forms a concave curved surface, and the total reflection layer 320 is laminated on the bottom surface of the lower frame 370 that forms a plane. Thus, an overall structure is formed between the semi-transmissive semi-reflective layer 310 and the total reflection layer 320 where the thickness of the central region is less than the thickness of the edge region, so as to obtain a depth-of-field visual effect as shown in Figure 4A . Also for example, in Figure 6C the shown implementation variant, the semi-transmissive semi-reflective layer 310 is laminated on the bottom surface of the upper frame 360 that forms a convex curved surface, and the total reflection layer 320 is laminated on the bottom surface of the lower frame 370 that forms a plane. Thus, an overall structure is formed between the semi-transmissive semi-reflective layer 310 and the total reflection layer 320 where the thickness of the central region is less than the thickness of the edge region, so as to obtain a depth-of-field visual effect as shown in Figure 4A .

[0090] It can be understood that the forming process, materials, colors, and other characteristics and parameters of the upper frame 360 and the lower frame 370 are similar to those of the first embodiment, so they will not be described repeatedly.

[0091] Fourth Embodiment

[0092] As shown in Figure 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 will not be described repeatedly. The difference is only that the thickness of the central region of the transparent frame 300 is greater than the thickness of its edge region. More specifically, one of the top surface 340 and the bottom surface 350 of the transparent frame 300 is a plane, and the other is a convex curved surface. For example, in Figure 5A the shown embodiment, the top surface 340 of the transparent frame 300 is a convex curved surface, and the bottom surface 350 is a plane; or, both the top surface 340 and the bottom surface 350 of the transparent frame 300 are convex curved surfaces; or, one of the top surface 340 and the bottom surface 350 of the transparent frame 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 Figure 5B the shown implementation variant, the top surface 340 of the transparent frame 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.

[0093] In this text and the accompanying drawings, both the "concave surface" and the "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 to say, if the center of the top surface 340 of the transparent skeleton 300 is sunken downward compared to its edge, the top surface 340 is a concave surface, as shown in Figure 4A and Figure 4B ; if the center of the top surface 340 of the transparent skeleton 300 bulges upward compared to its edge, the top surface 340 is a convex surface, as shown in Figure 5A and Figure 5B ; if the center of the bottom surface 350 of the transparent skeleton 300 is sunken upward compared to its edge, the bottom surface 350 is a concave surface, as shown in Figure 5B ; if the center of the bottom surface 350 of the transparent skeleton 300 bulges downward compared to its edge, the bottom surface 350 is a convex surface, as shown in Figure 4B .

[0094] When the semi-transmissive semi-reflective layer 310 and the total reflection layer 320 are respectively laminated on the top surface 340 and the bottom surface 350 of the transparent skeleton 300 that meet the structure of this embodiment as shown in Figure 5A , after the luminous optical pattern 330 undergoes multiple transmissions and reflections between the semi-transmissive semi-reflective layer 310 and the total reflection layer 320 along different light propagation paths 4100, 4110, 4120, it will present a regular depth of field similar to that shown in images J, K, and L in Figure 5A - that is, the spacing (between adjacent images) gradually increases (the spacing between image K and image L is greater than the spacing between image J and image K), the shape gradually bends and stretches, and the brightness gradually fades, presenting a depth-of-field visual effect (the imaging principles of virtual images K' and L' are similar to those of B' and C' above), and the stereoscopic vision reference effect is as shown in Figure 5C .

[0095] In some other implementation variations, the transparent skeleton 300 is replaced by an upper skeleton 360 and a lower skeleton 370 as shown in Figure 6D and Figure 6E . The top surface or the bottom surface of the upper skeleton 360 is laminated with the semi-transmissive semi-reflective layer 310, and the top surface or the bottom surface of the lower skeleton 370 is laminated with the total reflection layer 320. Moreover, both the surface of the upper skeleton 360 laminated with the semi-transmissive semi-reflective layer 310 and the surface of the lower skeleton 370 laminated with the total reflection layer 320 are planes or smooth surfaces with continuous curvature that meet the structural requirements of this embodiment. There are no special requirements for the shapes of the surfaces of the upper skeleton 360 and the lower skeleton 370 that are not laminated with the semi-transmissive semi-reflective layer 310 or the total reflection layer 320. For example, in Figure 6DIn the shown implementation variant, the transflective layer 310 is laminated on the top surface of the upper framework 360 that forms a convex curved surface, and the total reflection layer 320 is laminated on the bottom surface of the lower framework 370 that forms a flat surface. Thus, an overall structure is formed between the transflective layer 310 and the total reflection layer 320 where the thickness of the central region is greater than that of the edge region, so as to obtain the depth-of-field visual effect as shown in Figure 5A . Also, for example, in the implementation variant shown in Figure 6E , the transflective layer 310 is laminated on the bottom surface of the upper framework 360 that forms a concave curved surface, and the total reflection layer 320 is laminated on the bottom surface of the lower framework 370 that forms a flat surface. Thus, an overall structure is formed between the transflective layer 310 and the total reflection layer 320 where the thickness of the central region is greater than that of the edge region, so as to obtain the depth-of-field visual effect as shown in Figure 5A .

[0096] It can be understood that the forming process, materials, colors, and other characteristics and parameters of the upper framework 360 and the lower framework 370 are similar to those of the first embodiment, and thus will not be described repeatedly.

[0097] Fifth Embodiment

[0098] As shown in Figure 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 will not be described repeatedly. The difference lies only in that the light source and the optical pattern have different structures.

[0099] In the fifth embodiment, the light source is a side-entry light source 220 disposed on the side surface of the transparent framework 300 to illuminate the transparent framework 300. The side-entry light source 220 can be a PCB light board with LED lamp beads as shown in Figure 7A , or it can also be a light guide bar, 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.

[0100] The optical pattern 330 is integrated inside the transparent framework 300, for example, by means of printing, etching, laser engraving, bubbling, or insert molding of reflective materials or components inside the transparent framework 300.

[0101] As shown in Figure 7A , the side-entry light source 220 illuminates the optical pattern 330 in the transparent framework 300, such that the illuminated optical pattern 330 undergoes multiple transmissions and reflections along different light propagation paths 4160, 4170, 4180, 4190, 4200, 4210 between the transflective 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 Figure 7A - that is, a depth-of-field visual effect where the spacing (between adjacent images) is equal, the shapes are the same, and the brightness fades gradually.

[0102] It should be noted that regardless of the structure of the optical pattern 330 and the light source, when the optical pattern 330 is between the semi-transmissive semi-reflective layer 310 and the total reflection layer 320, the virtual image Q is the virtual image obtained by specular reflection of the image P by the total reflection layer 320. At this time, the brightness of the image P is greater than that of the virtual image Q; the formation paths of the virtual images R and S are as follows: the image P and the virtual image Q undergo specular reflection through the semi-transmissive semi-reflective layer 310 to obtain the virtual images R' and S', and the virtual images R' and S' undergo specular reflection through the total reflection layer 320 to obtain the virtual images R and S. At this time, the brightness of the virtual image R is greater than that of the virtual image S, and the brightnesses of the virtual images R and S are respectively lower than those of the image P and the virtual image Q, and the brightness difference between the virtual image Q and the virtual image R is relatively large, while the brightness differences between the image P and the virtual image Q and between the virtual image R and the virtual image S are relatively small; similarly, the formation paths of the virtual images T and U are as follows: the image R and the virtual image S undergo specular reflection through the semi-transmissive semi-reflective layer 310 to obtain the virtual images T' and U', and the virtual images T' and U' undergo specular reflection through the total reflection layer 320 to obtain the virtual images T and U. At this time, the brightness of the virtual image T is greater than that of the virtual image U, and the brightnesses of the virtual images T and U are respectively lower than those of the image R and the virtual image S, and the brightness difference between the virtual image S and the virtual image T is relatively large, while the brightness difference between the virtual image T and the virtual image U is relatively small. Thus, a depth-of-field effect with a gradually diminishing brightness pattern with different brightness differences is visually formed.

[0103] In Figure 7B In the shown implementation variant, if there is a set of two or more different optical patterns 330 arranged one above the other between the semi-transmissive semi-reflective layer 310 and the total reflection layer 320, a depth-of-field effect with a gradually diminishing brightness pattern with different brightness differences of this set of optical patterns 330 can be visually formed.

[0104] In Figure 7C In the shown implementation variant, if the optical pattern 330 between the semi-transmissive semi-reflective layer 310 and the total reflection layer 320 touches each other vertically and approaches the semi-transmissive semi-reflective layer 310 and the total reflection layer 320 with a very small gap, a depth-of-field effect with a gradually diminishing brightness and end-to-end connection can be visually formed.

[0105] In Figure 7D In the shown implementation variant, the transparent framework 300 can be replaced by an upper framework 360 and a lower framework 370 similar to the embodiment of Figure 6A After the luminous optical pattern 330 undergoes multiple transmissions and reflections between the semi-transmissive semi-reflective layer 310 and the total reflection layer 320 along different light propagation paths 4220, 4230, 4240, 4250, 4260, 4270, it will present a similar pattern to that of Figure 7DThe regular depth of field shown in images V, W, X, Y, Z, and AA - that is, the depth of field visual effect with equal spacing (between adjacent images), the same shape, and gradually diminishing brightness (the imaging principles of virtual images X', Y', Z', and AA' are similar to those of R', S', T', and U' above). It can be understood that in this implementation variant, if the lower frame 370 is an opaque part, the total reflection layer 320 is laminated with the top surface of the lower frame 370. At this time, the optical pattern 330 needs to be formed in the upper frame 360.

[0106] Sixth Embodiment

[0107] As Figure 8A shown, the overall structure of the vehicle trim according to the sixth embodiment is similar to that of the first embodiment, and the same parts will not be described repeatedly. The difference is only that the light source and the optical pattern have different structures.

[0108] In the sixth embodiment, the light source is a coherent light source 230, and the optical pattern is provided by a grating film 380. The grating film 380 is arranged on the side of the transparent frame 300, and the coherent light source 230 is located behind the grating film 380 to illuminate the grating film 380 and the transparent frame 300. The coherent light source 230 can be a laser emitter in the visible light band or other sources of visible coherent light. The optical pattern is designed in the grating film 380. When a single beam of coherent light propagating in a single direction passes through the grating film 380, it will continue to propagate in multiple divergent directions in the form of coherent light, and at this time the coherent light will carry the optical pattern. And when any beam of coherent light propagating in the divergent directions hits a plane and is reflected into the human eye, the human eye can see the optical pattern designed in the grating film 380.

[0109] As Figure 8A shown, after the light emitted by the coherent light source 230 passes through the grating film 380 with the optical pattern, the optical pattern 330 is projected onto the total reflection layer 320 or the semi-reflective semi-transmissive layer 310, so that the light of the optical pattern undergoes multiple transmissions and reflections between the semi-reflective 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 Figure 8A images AB, AC, and AD - that is, the depth of field visual effect with equal spacing (between adjacent images), the same shape, and gradually diminishing brightness (the imaging principles of virtual images AC' and AD' are similar to those of B' and C' above).

[0110] In Figure 8B the implementation variant shown, the transparent frame 300 can be similar to Figure 6AThe embodiment is replaced by an upper frame 360 and a lower frame 370. After the light of the optical pattern 330 undergoes multiple transmissions and reflections between the semi-transmissive and semi-reflective layer 310 and the total reflection layer 320 along different light propagation paths 4310, 4320, and 4330, it will present a regular depth of field similar to that shown in Figure 8B Images AE, AF, and AG in - that is, a depth of field visual effect with equal spacing (between adjacent images), the same shape, and gradually diminishing brightness (the imaging principles of virtual images AF' and AG' are similar to those of B' and C' above).

[0111] Seventh Embodiment

[0112] As shown in Figure 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 repeatedly. The difference is only that the light source and the optical pattern have different structures.

[0113] In the seventh embodiment, the light source is an in - mold point light source 240 integrated inside the transparent frame 300, and this in - mold point light source 240 forms the optical pattern 330 in this embodiment. The in - mold point light source 240 can be a light - emitting light source embedded in the transparent frame 300 achieved through processes such as insert molding.

[0114] As shown in Figure 9A When the in - mold point light source 240 located in the transparent frame 300 serves as both a light source and a light - emitting pattern 330, the light emitted by itself serves as the optical pattern 330. After undergoing multiple transmissions and reflections between the semi - transmissive and semi - reflective layer 310 and the total reflection layer 320 along different light propagation paths 4340, 4350, 4360, 4370, 4380, and 4390, it will present a regular depth of field similar to that shown in Figure 9A Images AH, AI, AJ, AK, AL, and AM in - that is, a depth of field visual effect with equal spacing (between adjacent images), the same shape, and gradually diminishing brightness (the imaging principles of virtual images AJ’AK’, AL’ and AM’ are similar to those of R’, S’, T’ and U’ above).

[0115] In Figure 9B In the shown implementation variant, the transparent frame 300 can be replaced by an upper frame 360 and a lower frame 370 similar to the embodiment in Figure 6A The in - mold point light source 240 can be embedded in the upper frame 360 or the lower frame 370, or placed between the upper frame 360 and the lower frame 370. The light emitted by the in - mold point light source 240 itself serves as the optical pattern 330. After undergoing multiple transmissions and reflections between the semi - transmissive and semi - reflective layer 310 and the total reflection layer 320 along different light propagation paths 4400, 4410, 4420, 4430, 4440, and 4450, it will present a regular depth of field similar to that shown in Figure 9BThe regular depth of field shown in images AN, AO, AP, AQ, AR, and AS - namely, the depth of field visual effect with equal spacing (between adjacent images), the same shape, and gradually diminishing brightness (the imaging principles of virtual images AP’AQ’, AR’, and AS’ are similar to those of R’, S’, T’, and U’ above). It can be understood that in this implementation variant, if the lower frame 370 is an opaque part, the total reflection layer 320 is laminated to the top surface of the lower frame 370. At this time, the in-mold point light source 240, i.e., the optical pattern 330, needs to be formed in the upper frame 360 or between the upper frame 360 and the lower frame 370.

[0116] Eighth Embodiment

[0117] As Figure 10A shown, 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 repeatedly. The difference is only that the light source and the optical pattern have different structures.

[0118] In the eighth embodiment, the light source is a side-entry light source 220 disposed on the side surface of the transparent frame 300. The side-entry light source 220 can be a PCB light board with LED lamp beads as Figure 10A shown, or it can be a light guide bar, 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.

[0119] The optical pattern 330 is provided by the in-mold light guide bar 250 at least partially disposed in the transparent frame 300. More specifically, the in-mold light guide bar 250 extends from the side-entry light source 220 into the interior of the transparent frame 300, and the optical pattern 330 is one or more light-emitting points formed on the in-mold light guide bar 250 and located in the transparent frame 300. The in-mold light guide bar 250 can be a common light guide bar, a soft light guide, an optical fiber, etc., and can be embedded in the transparent frame 300 by insert injection molding or two-color injection molding.

[0120] As Figure 10A shown, the light emitted by the side-entry light source 220 irradiates into the in-mold light guide bar 250, causing the in-mold light guide bar 250 to emit light. The light emitted by the in-mold light guide bar 250, as the optical pattern 330, undergoes multiple transmissions and reflections between the semi-reflective semi-transmissive layer 310 and the total reflection layer 320 along different light propagation paths 4460, 4470, 4480, 4490, 4500, 4510, and will present a regular depth of field similar to that shown in Figure 10A images AT, AU, AV, AW, AX, and AY - namely, the depth of field visual effect with equal spacing (between adjacent images), the same shape, and gradually diminishing brightness (the imaging principles of virtual images AV’AW’, AX’, and AY’ are similar to those of R’, S’, T’, and U’ above).

[0121] In Figure 10B the illustrated implementation variant, the transparent skeleton 300 can be replaced by an upper skeleton 360 and a lower skeleton 370 similar to those in the embodiment as Figure 6A . The in-mold light guide bar 250 can be embedded in the upper skeleton 360 or the lower skeleton 370, or can be placed between the upper skeleton 360 and the lower skeleton 370. After the light emitted by the in-mold light guide bar 250 undergoes multiple transmissions and reflections between the semi-transmissive semi-reflective layer 310 and the total reflection layer 320 along different light propagation paths 4520, 4530, 4540, 4550, 4560, 4570, it will present a regular depth of field similar to that shown in the images AZ, image BA, image BB, image BC, image BD, image BE in Figure 10B , that is, a depth of field visual effect with equal spacing (between adjacent images), the same shape, and gradually diminishing brightness (the imaging principles of the virtual images BB’, BC’, BD’ and BE’ are similar to those of the above R’, S’, T’ and U’). It can be understood that in this implementation variant, if the lower skeleton 370 is a non-transparent part, the total reflection layer 320 is laminated with the top surface of the lower skeleton 370. At this time, the in-mold light guide bar 250, that is, the optical pattern 330, needs to be formed in the upper skeleton 360, or formed between the upper skeleton 360 and the lower skeleton 370.

[0122] Ninth Embodiment

[0123] As Figure 11A shown, the overall structure of the vehicle trim according to the ninth embodiment is similar to that of the first embodiment, and the same parts will not be described repeatedly. The difference lies only in that the light source and the optical pattern have different structures.

[0124] In the ninth embodiment, the light source is a conformal lamp panel light source 260 disposed on the bottom surface 350 of the transparent skeleton 300, and this conformal lamp panel light source 260 provides the optical pattern 330 in this embodiment. The conformal lamp panel light source 260 can be the light emitted by the light-emitting elements on a rigid or soft conformal lamp panel whose shape is the same as the surface shape of the bottom surface 350 of the transparent skeleton 300. This light serves both as the light source and undergoes multiple transmissions and reflections as the optical pattern 330 to form a regular depth of field visual effect. The shape of the conformal lamp panel is the same as the surface shape of the bottom surface 350 of the transparent skeleton 300, and it is laminated with the bottom surface of the transparent skeleton 300 by means of structural installation, adhesive, or insert injection molding, etc.

[0125] As described above, the total reflection layer 320 can be laminated to the bottom surface 350 of the transparent skeleton 300 by means of painting, screen printing, film laminating, electroplating, hot stamping or PVD process. The bottom surface 350 of the transparent skeleton 300 can also be configured to have total optical reflection, or a part with total reflection property can be used to be attached to the bottom surface 350 of the transparent skeleton 300 for lamination. In this embodiment, the total reflection layer 320 can also be formed on the mounting carrier of the shaped light panel light source 260 (i.e., the shaped light panel for mounting the shaped light panel light source 260) by means of painting, screen printing, film laminating, electroplating, hot stamping or PVD process. Since the shape of the shaped light panel is the same as the surface of the bottom surface 350 of the transparent skeleton 300 and is laminated to the bottom surface 350 of the transparent skeleton 300 by means of structural mounting, adhesive or insert injection molding, etc., the total reflection function on the bottom surface 350 of the transparent skeleton 300 can be achieved after lamination.

[0126] As Figure 11A shown, the shaped light panel light source 260 located at the bottom of the transparent skeleton 300 serves as a light source and also as a light-emitting pattern 330. The light emitted by itself serves as an optical pattern 330 and undergoes multiple transmissions and reflections between the semi-reflective semi-transmissive layer 310 and the total reflection layer 320 along different light propagation paths 4580, 4590, 4600, and will present a regular depth of field similar to that shown in Figure 11A the images BF, BG, BH in - that is, a depth of field visual effect with equal spacing (between adjacent images), the same shape and gradually diminishing brightness (the imaging principles of the virtual images BG’ and BH’ are similar to those of B’ and C’ above).

[0127] In Figure 11B the shown implementation variant, the transparent skeleton 300 can be replaced by an upper skeleton 360 and a lower skeleton 370 similar to the Figure 6A embodiment. The total reflection layer 320 and the shaped light panel of the shaped light panel light source 260 are laminated to the top surface or the bottom surface of the lower skeleton 370. After the light emitted by the shaped light panel light source 260 itself serves as an optical pattern 330 and undergoes multiple transmissions and reflections between the semi-reflective semi-transmissive layer 310 and the total reflection layer 320 along different light propagation paths 4610, 4620, 4630, it will present a regular depth of field similar to that shown in Figure 11B the images BI, BJ, BK in - that is, a depth of field visual effect with equal spacing (between adjacent images), the same shape and gradually diminishing brightness (the imaging principles of the virtual images BJ’ and BK’ are similar to those of B’ and C’ above). It can be understood that in this implementation variant, if the lower skeleton 370 is a non-transparent part, the total reflection layer 320 and the shaped light panel of the shaped light panel light source 260 are laminated to the top surface of the lower skeleton 370.

[0128] Tenth Embodiment

[0129] As Figure 12A shown, 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 repeatedly. The difference is only that the light source and the optical pattern have different structures, 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 the area that needs to be visible functionally, and the non-light-emitting area R2 is defined as the area that is not visible functionally. The non-light-emitting area R2 can be shielded by means such as physical objects, painting, film pasting, silk screening, etc. to achieve the effect of being visually invisible.

[0130] In the tenth embodiment, the reflective optical pattern 330 is formed on the bottom surface 350 or the top surface 340 of the transparent skeleton 300. At the same time, the light source is the conformal lamp panel light source 260 disposed on the bottom surface 350 of the transparent skeleton 300, and the position where the conformal lamp panel light source 260 is arranged is located in the non-light-emitting area R2.

[0131] The conformal lamp panel light source 260 can be the light emitted by the light-emitting elements on a rigid or soft conformal lamp panel whose shape is the same as the surface of the bottom surface 350 of the transparent skeleton 300. Since the conformal lamp panel light source 260 is arranged in the non-light-emitting area R2, this light only serves as a light source. The shape of the conformal lamp panel is the same as the surface of the bottom surface 350 of the transparent skeleton 300, and it is laminated with the bottom surface 350 of the transparent skeleton 300 by means of structural installation, adhesive, or insert injection molding.

[0132] As described above, the total reflection layer 320 can be laminated with the bottom surface 350 of the transparent skeleton 300 by means of painting, silk screening, film pasting, electroplating, hot stamping, or PVD process. The bottom surface 350 of the transparent skeleton 300 can also be constructed to be optically totally reflective, or it can be laminated with the bottom surface 350 of the transparent skeleton 300 by fitting an additional part with total reflection properties. In this embodiment, the total reflection layer 320 can also be formed on the installation carrier of the conformal lamp panel light source 260 (i.e., the conformal lamp panel for installing the conformal lamp panel light source 260) by means such as painting, silk screening, film pasting, electroplating, hot stamping, or PVD. Since the shape of the conformal lamp panel is the same as the surface of the bottom surface 350 of the transparent skeleton 300 and it is laminated with the bottom surface 350 of the transparent skeleton 300 by means of structural installation, adhesive, or insert injection molding, the total reflection function on the bottom surface 350 of the transparent skeleton 300 can be achieved after lamination.

[0133] The optical pattern 330 can be a 3D feature that is locally concave or convex on the bottom surface 350 or the top surface 340 of the transparent skeleton 300 (no special treatment or local polishing, leather texture treatment, etc. may be done on the 3D feature), or it can be a graphic feature attached to the bottom surface 350 or the top surface 340 of the transparent skeleton 300, or on the surface where the total reflection layer 320 or the semi-transparent and semi-reflective layer 310 is respectively laminated with the bottom surface 350 or the top surface 340 of the transparent skeleton 300 through processes such as spraying, printing, silk-screen printing, PVD, electroplating, film laminating, hot stamping, etc. The optical pattern 330 can even be a part with reflective 3D or 2D features on an additional component to be laminated on the bottom surface 350 or the top surface 340 of the transparent skeleton 300. As long as the optical pattern 330 can present different brightness effects that are recognizable by the human eye when illuminated by light on the total reflection layer 320 or the semi-transparent and semi-reflective layer 310 after illumination, multiple reflections and transmissions can occur between the semi-transparent and semi-reflective layer 310 and the total reflection layer 320 to form a regular depth-of-field visual effect. The present utility model does not limit the type of such optical pattern 330.

[0134] As Figure 12A shown, the light emitted by the conformal light plate light source 260 can propagate within the transparent skeleton 300. When the light emitted by the conformal light plate light source 260 illuminates the optical pattern 330, its patterned light undergoes multiple transmissions and reflections along different light propagation paths 4640, 4650, 4660 between the semi-transparent and semi-reflective layer 310 and the total reflection layer 320, and will present a regular depth-of-field similar to that shown in the images BL, BM, BN in Figure 12A , that is, a depth-of-field visual effect with equal spacing (between adjacent images), the same shape, and gradually diminishing brightness (the imaging principles of the virtual images BM’ and BN’ are similar to those of B’ and C’ above).

[0135] In Figure 12B the shown implementation variant, the transparent skeleton 300 can be replaced by an upper skeleton 360 and a lower skeleton 370 similar to the embodiment in Figure 6A . The total reflection layer 320 and the conformal light plate of the conformal light plate light source 260 are laminated 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 conformal light plate light source 260 illuminates the optical pattern 330, its patterned light undergoes multiple transmissions and reflections along different light propagation paths 4670, 4680, 4690 between the semi-transparent and semi-reflective layer 310 and the total reflection layer 320, and will present a similar one as shown in Figure 12BThe regular depth of field shown in the middle images BO, BP, and BQ - that is, the depth-of-field visual effect with equal spacing (between adjacent images), the same shape, and gradually diminishing brightness (the imaging principles of the virtual images BP' and BQ' are similar to those of B' and C' above). It can be understood that in this implementation variant, if the lower frame 370 is a non-transparent part, the total reflection layer 320 and the conformal light panel of the conformal light panel light source 260 are laminated to the top surface of the lower frame 370, and the optical pattern 330 can be formed on the top surface of the lower frame 370.

[0136] Eleventh Embodiment

[0137] As Figure 13A shown, 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 repeatedly. The difference lies only in that the light source and the optical pattern have different structures, and the transparent frame 300 is divided into a light-emitting area R1 and a non-light-emitting area R2. The light-emitting area R1 is defined as the area that needs to be visible functionally, and the non-light-emitting area R2 is defined as the area that is not visible functionally. It can be shielded by physical objects, painting, film pasting, silk screening, or other similar means to achieve the effect of being visually invisible.

[0138] In the eleventh embodiment, the reflective optical pattern 330 is formed on the bottom surface 350 or the top surface 340 of the transparent frame 300. At the same time, the light source is the conformal light panel light source 260 arranged on the top surface 340 of the transparent frame 300, and the position where the conformal light panel light source 260 is arranged is located in the non-light-emitting area R2.

[0139] The conformal light panel light source 260 can be the light emitted by the light-emitting elements on a rigid or soft conformal light panel whose shape is the same as the surface of the top surface 340 of the transparent frame 300. Since the conformal light panel light source 260 is arranged in the non-light-emitting area R2, this light only serves as a light source. The shape of the conformal light panel is the same as the surface of the top surface 340 of the transparent frame 300, and it is laminated to the top surface 340 of the transparent frame 300 by means of structural installation, adhesive, or insert molding.

[0140] As described above, the transflective layer 310 can be laminated on the top surface 340 of the transparent frame 300 by pasting a transflective film, spraying / brushing a transflective coating, PVD, or fitting another part with transflective characteristics to the top surface 340 of the transparent frame 300. In this embodiment, the transflective layer 310 can also be formed on the mounting carrier of the shaped light panel light source 260 (i.e., the shaped light panel for mounting the shaped light panel light source 260) by processes such as painting, screen printing, film laminating, electroplating, hot stamping, or PVD. Since the shape of the shaped light panel is the same as the surface profile of the top surface 340 of the transparent frame 300 and is laminated to the top surface 340 of the transparent frame 300 by methods such as structural mounting, adhesives, or insert molding, the transflective function on the top surface 340 of the transparent frame 300 can be achieved after lamination.

[0141] The optical pattern 330 can be a 3D feature with local concavities or protrusions on the bottom surface 350 or the top surface 340 of the transparent frame 300 (no special treatment or local grinding, texture, etc. may be performed on the 3D feature), or it can be a graphic feature attached to the bottom surface 350 or the top surface 340 of the transparent frame 300, or on the surfaces where the total reflection layer 320 or the transflective layer 310 is laminated to the bottom surface 350 or the top surface 340 of the transparent frame 300 through processes such as spraying, printing, screen printing, PVD, electroplating, film laminating, hot stamping, etc. The optical pattern 330 can even be a part with reflective 3D or 2D features on an additional component to be laminated to the bottom surface 350 or the top surface 340 of the transparent frame 300. As long as the optical pattern 330 can present different brightness effects that are recognizable by the human eye when illuminated on the total reflection layer 320 or the transflective layer 310 after illumination, a regular depth-of-field visual effect can be formed through multiple reflections and transmissions between the transflective layer 310 and the total reflection layer 320. The present invention does not limit the type of such optical pattern 330.

[0142] As Figure 13A shown, the light emitted by the shaped light panel light source 260 can propagate within the transparent frame 300. When the light emitted by the shaped light panel light source 260 illuminates the optical pattern 330, its patterned light undergoes multiple transmissions and reflections along different light propagation paths 4700, 4710, 4720 between the transflective layer 310 and the total reflection layer 320, presenting a regular depth-of-field similar to that shown in images BR, BS, BT in Figure 13A - that is, a depth-of-field visual effect with equal spacing (between adjacent images), the same shape, and gradually diminishing brightness (the imaging principles of virtual images BS’ and BT’ are similar to those of B’ and C’ above).

[0143] In Figure 13B the shown implementation variant, the transparent frame 300 can be similar to Figure 6AThe embodiment is replaced by an upper framework 360 and a lower framework 370. The conformal light plate of the transflective layer 310 and the conformal light plate light source 260 is laminated to the top or bottom surface of the upper framework 360, and the optical pattern 330 can be formed on the top or bottom surface of the upper framework 360 or the top or bottom surface of the lower framework 370. When the light emitted by the conformal light plate light source 260 illuminates the optical pattern 330, the patterned light undergoes multiple transmissions and reflections between the transflective layer 310 and the total reflection layer 320 along different light propagation paths 4730, 4740, 4750, and will present a regular depth of field similar to that shown in Figure 13B the depth of field visual effects of the images BU, BV, BW in the figure - that is, the depth of field with equal spacing (between adjacent images), the same shape, and gradually diminishing brightness (the imaging principles of the virtual images BV' and BW' are similar to those of B' and C' above). It can be understood that in this embodiment variant, if the lower framework 370 is a non-transparent member, the total reflection layer 320 is laminated to the top surface of the lower framework 370, and the optical pattern 330 can be formed on the top surface of the lower framework 370.

[0144] Twelfth Embodiment

[0145] As Figure 14A shown, the overall structure of the vehicle trim according to the twelfth embodiment is similar to that of the first embodiment, and the same parts will not be described repeatedly. The difference is only that the light source and the optical pattern have different structures, and the transparent framework 300 is formed by an injection molding process and fine particles are mixed into the injection molding material.

[0146] In the twelfth embodiment, the light source is a side-entry light source 220 disposed on the side surface of the transparent framework 300. The side-entry light source 220 can be a PCB light plate with LED lamp beads as Figure 10A shown, or a light guide bar, 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 a light source.

[0147] The optical pattern 330 is provided by a pattern light-transmitting layer 390 disposed on the side surface of the transparent framework 300. More specifically, the pattern light-transmitting layer 390 is disposed between the side-inlet light source 220 and the transparent framework 300. The pattern area on the pattern light-transmitting layer 390 is light-transmitting, and the non-pattern area is non-light-transmitting, so as to ensure that the light emitted by the side-inlet light source 220 has a specific light pattern after passing through the pattern light-transmitting layer 390. Since tiny particles are mixed into the injection molding material of the transparent framework 300, these tiny particles are evenly distributed throughout the transparent framework 300 during the injection molding of the transparent framework 300 and are basically invisible under normal visual conditions. However, when the light with a specific light pattern is emitted from the side-inlet light source 220 through the pattern light-transmitting layer 390 into the transparent framework 300 with tiny particles, the light is scattered when it encounters these tiny particles, so that the specific light pattern can be seen by the human eye within the transparent framework 300. Any luminous point on the light line of this specific light pattern constitutes the optical pattern 330.

[0148] The pattern light-transmitting layer 390 can be a pure transparent plate, on which a light-transmitting area and a non-light-transmitting area with a specific pattern are formed by methods such as film sticking (the light-transmitting and non-light-transmitting on the film are realized by printing, screen printing or directly punching holes, etc.), masking spray painting, screen printing, electroplating, PVD, hot stamping, masking with another part, etc.; or it can also be an opaque plate, and a light-transmitting hole is formed on the opaque plate by methods such as punching or laser engraving to realize a light-transmitting area and a non-light-transmitting area with a specific pattern; or even it can be a film, on which a light-transmitting area and a non-light-transmitting area with a specific pattern are formed by methods such as film sticking, spray painting, screen printing, electroplating, PVD, hot stamping, masking with another part, etc. The present invention does not limit the type of this pattern light-transmitting layer 390.

[0149] As Figure 14A shown, since tiny particles are mixed into the injection molding material of the transparent framework 300, the light that illuminates the optical pattern 330 formed by these tiny particles undergoes multiple transmissions and reflections along different light propagation paths 4760, 4770, 4780, 4790, 4800, 4810 between the semi-transmissive semi-reflective layer 310 and the total reflection layer 320, and will present a regular depth of field similar to that shown in Figure 14A the images BX, BY, BZ, CA, CB, CC, that is, a depth-of-field visual effect with equal spacing (between adjacent images), the same shape and gradually diminishing brightness (the imaging principles of the virtual images BZ’CA’, CB’ and CC’ are similar to those of the above R’, S’, T’ and U’).

[0150] In Figure 14B the shown implementation variant, the transparent framework 300 can be similar to Figure 6AThe embodiment is replaced by an upper framework 360 and a lower framework 370. Tiny particles are mixed into the injection-molded plastics of the upper framework 360 and the lower framework 370. At this time, the light of the optical pattern 330 can be injected into either the upper framework 360 or the lower framework 370. After the light of the optical pattern 330 undergoes multiple transmissions and reflections along different light propagation paths 4820, 4830, 4840, 4850, 4860, 4870 between the semi-transmissive and semi-reflective layer 310 and the total reflection layer 320, it will present a regular depth of field similar to that shown in Figure 14B the images CD, CE, CF, CG, CH, CI in the figure - that is, a depth-of-field visual effect with equal spacing (between adjacent images), the same shape, and gradually diminishing brightness (the imaging principles of the virtual images CF’, CG’, CH’, and CI’ are similar to those of the above R’, S’, T’, and U’). It can be understood that in this implementation variant, if the lower framework 370 is an opaque part, the total reflection layer 320 is laminated with the top surface of the lower framework 370. At this time, the light of the optical pattern 330 needs to be injected into the upper framework 360.

[0151] Thirteenth Embodiment

[0152] As Figure 15A shown, 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 repeatedly. The difference lies only in that the light source and the optical pattern have different structures.

[0153] In the thirteenth embodiment, the light source is a side-entry light source 220 disposed on the side of the transparent framework 300. The side-entry light source 220 can be a PCB lamp board with LED lamp beads as Figure 10A shown, or a light guide bar, 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.

[0154] The optical pattern 330 is provided by a pattern light-transmitting layer 390 disposed on the side of the transparent framework 300. More specifically, a pattern light-transmitting layer 390 is disposed between the side-entry light source 220 and the transparent framework 300. The pattern area on the pattern light-transmitting layer 390 is light-transmissive, and the non-pattern area is non-light-transmissive, so as to ensure that the light emitted by the side-entry light source 220 has a specific light pattern after passing through the pattern light-transmitting layer 390. This light with a special light pattern is injected into the transparent framework 300 and then irradiates on the total reflection layer 320 or the semi-transmissive and semi-reflective layer 310 to form the optical pattern 330.

[0155] The pattern light-transmitting layer 390 can be a pure transparent plate, on which a light-transmitting area and a non-light-transmitting area with a specific pattern are formed by methods such as film sticking (the light-transmitting and non-light-transmitting areas on the film are achieved by printing, screen printing, or directly punching holes, etc.), masking spray painting, screen printing, electroplating, PVD, hot stamping, masking with another part, etc.; or it can also be an opaque plate, and a light-transmitting hole is formed on the opaque plate by methods such as punching or laser engraving to achieve a light-transmitting area and a non-light-transmitting area with a specific pattern; or even it can be a film, on which a light-transmitting area and a non-light-transmitting area with a specific pattern are formed by methods such as film sticking, spray painting, screen printing, electroplating, PVD, hot stamping, masking with another part, etc. The present invention does not limit the type of this pattern light-transmitting layer 390.

[0156] As Figure 15A shown, when light with a special light pattern irradiates on the total reflection layer 320 or the semi-transparent and semi-reflective layer 310, an optical pattern 330 is formed. The light of this optical pattern 330 undergoes multiple transmissions and reflections along different light propagation paths 4880, 4890, 4900 between the semi-transparent and semi-reflective layer 310 and the total reflection layer 320, and will present a regular depth of field similar to that shown in Figure 15A images CJ, CK, CL - that is, a depth-of-field visual effect with equal spacing (between adjacent images), the same shape, and gradually diminishing brightness (the imaging principles of virtual images CK' and CL' are similar to those of B' and C' above).

[0157] In Figure 15B the shown implementation variant, the transparent skeleton 300 can be replaced by an upper skeleton 360 and a lower skeleton 370 similar to the embodiment in Figure 6A When light with a special light pattern irradiates on the total reflection layer 320 or the semi-transparent and semi-reflective layer 310, an optical pattern 330 is formed. The light of this optical pattern 330 undergoes multiple transmissions and reflections along different light propagation paths 4910, 4920, 4930 between the semi-transparent and semi-reflective layer 310 and the total reflection layer 320, and will present a regular depth of field similar to that shown in Figure 15B images CM, CN, CO - that is, a depth-of-field visual effect with equal spacing (between adjacent images), the same shape, and gradually diminishing brightness (the imaging principles of virtual images CN' and CO' are similar to those of B' and C' above).

[0158] Figures 16A to 16C shows a physical application of a vehicle trim according to the present invention, that is, a door regular depth-of-field lighting trim assembly 500 is shown, which mainly consists of a screw 540, a door trim panel 530, a lamp module housing 520, a direct-downlight source 210, a light homogenizing plate 510, and a transparent skeleton 300. The semi-transparent and semi-reflective layer 310 is a film, for example, it is laminated on the top surface 340 of the transparent skeleton 300 by the IML (in-mold insert molding) method (that is Figure 16Bthe side far away from the direct - down light source 210). The total - reflection layer 320 is, for example, laminated on the bottom surface 350 of the transparent skeleton 300 (i.e., Figure 16B the side close to the direct - down light source 210). On the total - reflection layer 320, for example, through a laser engraving process, a local PVD layer is engraved through to obtain a light - transmissive optical pattern 330. The direct - down light source 210 is, for example, a light strip connected to the lamp module housing 520 by pasting. The light - homogenizing plate 510 is, for example, fixed on the lamp module housing 520 by snap - connection. The transparent skeleton 300 laminated with the semi - reflective and semi - transmissive layer 310 and the total - reflection layer 320 is, for example, fixed on the lamp module housing 520 by snap - connection. Finally, the lamp module housing 520 equipped with the direct - down light source 210, the light - homogenizing plate 510, and the transparent skeleton 300 is fixedly connected to the door trim panel 530 by screws 540, and finally forms the door regular depth - of - field lighting trim assembly 500.

[0159] In the door regular depth - of - field lighting trim assembly 500, the light emitted by the direct - down light source 210 is optically mixed and homogenized by the light - homogenizing plate 510. The light that has completed the mixing and homogenizing then enters between the semi - reflective and semi - transmissive layer 310 and the total - reflection layer 320 through the light - transmissive optical pattern 330. The light with the optical pattern 330 presents a regular depth - of - field lighting effect after multiple transmissions and reflections between the semi - reflective and semi - transmissive layer 310 and the total - reflection layer 320. The specific optical path can be referred to Figure 2A . As Figure 16C shown, since the semi - reflective and semi - transmissive layer 310 and the total - reflection layer 320 are smooth curved surfaces parallel to each other, the presented lighting effect is a depth - of - field visual effect with equal spacing (between adjacent images), the same shape, and gradually diminishing brightness. The specific stereoscopic visual effect can be referred to Figure 2B .

[0160] In addition, as described previously, in various embodiments, by lighting the light sources 210, 220, 230, 240, 250, 260, the optical pattern 330 is irradiated by light, and the irradiated light of the optical pattern 330 undergoes multiple reflections and transmissions between the semi-transmissive semi-reflective layer 310 and the total reflection layer 320, enabling an image of the optical pattern 330 in the multiple reflection and transmission attenuation optical transfer path to be observable at the same observation position, forming a variety of regularly arranged depth-of-field visual effects. At the same time, by programming the control procedures for multiple LEDs or other light units constituting the light sources in the light sources 210, 220, 230, 240, 250, 260, the light sources 210, 220, 230, 240, 250, 260 can be controlled to remain constantly lit as a whole or change in brightness or color as a whole in a set manner, forming a static or dynamic depth-of-field light effect as a whole; or by programming the control procedures for multiple LEDs or other light units constituting the light sources in the light sources 210, 220, 230, 240, 250, 260, the light sources can be controlled to change in brightness or color locally in a set manner, achieving a locally dynamic depth-of-field light effect.

However, it can be understood that under the creative concept of the present invention, those skilled in the art can make various changes and improvements to the above-disclosed concept, but all fall within the protection scope of the present invention.
