Vehicle trim

Abstract

The invention relates to a vehicle trim part which comprises a dynamic light source, a pattern light-transmitting layer and an illuminated face, the dynamic light source has a linear moving track, the pattern light-transmitting layer comprises a light-transmitting area with a pattern, and the vehicle trim part is constructed to be capable of moving along the moving track when the dynamic light source moves along the moving track. Light emitted by the dynamic light source penetrates through the light-permeable area to illuminate the pattern, and the pattern is projected to the illuminated surface to form a dynamic visual effect that the pattern moves close to or far away from an observer and is large in the near and small in the far. As the process of pattern displacement and size stretching / compression conforms to the visual rule that a moving object is observed from far to near or from near to far by human eyes, the dynamic lighting effect that a person gets close to / away from an observer can be generated, and the sensory experience of a user is improved.

Description

Technical Field

[0001] The present invention relates to the technical field of vehicle parts, and more specifically, to a vehicle trim. Background Art

[0002] At present, the light effects of indirect or back-transparent projection ambient lights as interior and exterior decorations of vehicles are usually 2D. In order to increase the sense of luxury of vehicle decorations, it is now expected to introduce an indirect or back-transparent projection ambient light with a "quasi-three-dimensional" dynamic visual effect on the vehicle, which requires further design of the key components of the projection ambient light and its corresponding structure, scheme and arrangement relationship. Summary of the invention

[0003] The purpose of the present invention is to improve the lighting effect of an indirect or rear projection ambient light of a vehicle from a 2D (two-dimensional) visual effect to a dynamic 3D (three-dimensional) visual effect. More specifically, the purpose of the present invention is to provide a vehicle trim that provides a "quasi-stereoscopic" dynamic imaging simulated pattern / texture visual effect that moves toward or away from an observer and is larger near and smaller far away.

[0004] To this end, a first aspect of the present invention provides a vehicle trim, comprising a dynamic light source, a patterned light-transmitting layer and an illuminated surface, wherein the dynamic light source has a linear moving trajectory, and the patterned light-transmitting layer comprises a light-transmitting area with a pattern, wherein the vehicle trim is configured such that when the dynamic light source moves along the moving trajectory, light emitted by the dynamic light source passes through the light-transmitting area to illuminate the pattern, and the pattern is projected onto the illuminated surface to form a dynamic visual effect of moving towards or away from an observer and appearing larger when closer and smaller when farther away.

[0005] According to the above technical concept, the present invention may further include any one or more of the following optional forms.

[0006] In some optional forms, the angle between the moving trajectory of the dynamic light source and the illuminated surface is greater than 0° and less than 180°, and / or the angle between the patterned light-transmitting layer and the illuminated surface is greater than 0° and less than 180°.

[0007] In some optional forms, the patterned light-transmitting layer is configured as one of the following forms: a patterned light-transmitting plate, a patterned hollow plate, a patterned light-transmitting film, a 3D free-form surface light-transmitting plate, a micro-nano textured light-transmitting film, and a light diffraction light-transmitting film.

[0008] In some optional forms, the vehicle trim further includes at least one reflective surface, and the reflective surface is configured to reflect the light emitted by the dynamic light source toward the patterned light-transmitting layer, or to reflect the light passing through the patterned light-transmitting layer toward the illuminated surface.

[0009] In some optional forms, the vehicle trim includes multiple groups of dynamic light sources and / or multiple patterned light-transmitting layers, so that the light passing through the patterned light-transmitting layers and projected onto the illuminated surface forms a dynamic visual effect formed by the superposition of multiple patterns.

[0010] A second aspect of the present invention provides a vehicle trim, comprising a dynamic light source, a patterned reflective layer and an illuminated surface, wherein the dynamic light source has a linear moving trajectory, and the patterned reflective layer comprises a reflective area with a pattern, wherein the vehicle trim is configured such that when the dynamic light source moves along the moving trajectory, light emitted by the dynamic light source is irradiated on the reflective area to illuminate the pattern, and after being reflected by the reflective area, the pattern is projected onto the illuminated surface to form a dynamic visual effect of moving towards or away from an observer and appearing larger when near and smaller when far.

[0011] In some optional forms, the angle between the moving trajectory of the dynamic light source and the illuminated surface is greater than or equal to 0° and less than or equal to 180°, and / or the angle between the patterned reflective layer and the illuminated surface is greater than or equal to 0° and less than or equal to 180°.

[0012] In some optional forms, the pattern reflective layer is configured as one of the following forms: a pattern reflective plate, a pattern reflective film, a 3D free-form surface reflective plate, a micro-nano texture reflective film, and a light diffraction reflective film.

[0013] In some optional forms, the vehicle trim further includes at least one reflective surface, and the reflective surface is configured to reflect the light emitted by the dynamic light source toward the patterned reflective layer, or to reflect the light reflected by the patterned reflective layer toward the illuminated surface.

[0014] In some optional forms, the vehicle trim includes multiple groups of dynamic light sources and / or multiple patterned reflective layers, so that the light reflected onto the illuminated surface via the patterned reflective layers forms a dynamic visual effect formed by superimposing multiple patterns.

[0015] In some optional forms, the dynamic light source includes a plurality of point light sources that are linearly arranged and controlled to light up in sequence, or the dynamic light source is a single point light source that is driven by a driving mechanism to move along the moving track.

[0016] In some optional forms, the movement trajectory of the dynamic light source is periodic, and the projection formed by the pattern projected onto the illuminated surface increases monotonically or decreases monotonically within one movement cycle of the dynamic light source.

[0017] In some optional forms, the vehicle trim includes a flat translucent illuminated screen, and one side surface of the illuminated screen forms the illuminated surface.

[0018] In some optional forms, the vehicle trim is applied to at least one of the following vehicle parts: front bumper, hood, fender, side door, side wall, tailgate, rear bumper, instrument panel, door inner panel, auxiliary instrument panel, floor, roof, headrest, seat back.

[0019] Compared with the prior art, the vehicle trim according to the present invention has multiple beneficial technical effects, especially: the vehicle trim utilizes a dynamic light source and a layer with a translucent or reflective pattern to illuminate the patterned light onto the illuminated surface, the pattern / texture is always illuminated by the light source and forms a projection pattern on the illuminated surface, and the projection pattern on the illuminated surface undergoes continuous displacement and size stretching / compression through changes in the illumination position of the dynamic light source. Since the process of pattern displacement and size stretching / compression conforms to the visual law of human eyes observing a moving object from far to near or from near to far, it can produce a dynamic light effect of light effect approaching / moving away from the observer, thereby enhancing the user's sensory experience.

[0036] The elements in the drawings are shown for simplicity and clarity and are not necessarily drawn in exact proportions and shapes. It should be understood that the drawings are not only used to explain and illustrate the present invention, but also to help define the present invention when necessary. DETAILED DESCRIPTION

[0037] The implementation and use of specific embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely illustrative of specific ways to implement and use the invention, and are not intended to limit the scope of the invention.

[0038] In this article, when describing the position of a structure, expressions indicating directions such as "up", "down", "left", and "right" are not absolute but relative. For example, when the components are arranged as shown in the figure, these directional expressions are appropriate, but when the positions of the components in the figure are changed, these directional expressions should also be changed accordingly.

[0039] like Figure 1A As shown, the vehicle trim according to the present invention can be arranged on the outside of the vehicle, for example, it can be specifically applied to at least one of the following vehicle parts: a front bumper FB with a grille, an engine hood HD, a fender FD, a side door SD, a side panel SB, a tailgate TG, a rear bumper RB, etc. Figures 1B to 1D As shown, the vehicle trim according to the present invention can also be set in the interior of the vehicle, for example, it can be specifically applied to at least one of the following vehicle components: instrument panel IP, door inner panel DP, auxiliary instrument panel CS, floor FL, interior roof CL, headrest HR, seat back SK, etc.

[0040] First embodiment

[0041] like FIG. 2A to FIG. 2C As shown, the vehicle trim according to the first embodiment includes a dynamic light source 100 , a flat patterned light-transmitting layer 200 , and a flat illuminated screen 400 , one side surface (ie, the right side surface in the figure) of the illuminated screen 400 forming an illuminated surface 410 .

[0042] The dynamic light source 100 has a linear effective moving trajectory, that is, each irradiation position on the moving trajectory is an effective irradiation position. Here, the "effective irradiation position" refers to the corresponding position where the light emitted by the point light source at this position can enter the pattern light-transmitting layer 200 and form a projection pattern on the illuminated surface 410. In other words, if the light emitted by the point light source at a certain position cannot enter the pattern light-transmitting layer 200 or cannot form a projection pattern on the illuminated surface 410, then the position does not belong to the "effective irradiation position" here. It can be understood that the light source form and movement form of the dynamic light source 100 can be of many types, and the present invention does not limit this. In the illustrated embodiment, the dynamic light source 100 includes a plurality of point light sources that are arranged linearly and controlled to light up in sequence, that is, the movement of the point light source position can be achieved by software pipeline programming of these linearly arranged point light sources. That is, in the illustrated embodiment, the moving trajectory of the dynamic light source 100 refers to the connecting line of the positions of the point light sources that are lit up in sequence (i.e., the lighting trajectory), rather than the motion trajectory of mechanical movement. According to other implementation variations, the dynamic light source 100 may also be, for example, a single point light source driven by a driving mechanism to move along its movement trajectory.

[0043] The patterned light-transmitting layer 200 at least includes a light-transmitting area 210 with a pattern / texture. In this first embodiment, the patterned light-transmitting layer 200 is configured as a patterned hollow plate, which includes a light-transmitting area 210 with a hollowed pattern and a non-light-transmitting area 220. The structural form of the patterned light-transmitting layer 200 can be of many types, as long as it has at least a light-transmitting area thereon, and the light-transmitting area forms a light-transmitting pattern with a specific design intention, and the present invention does not limit this. According to other implementation variations, the patterned light-transmitting layer 200 can also be configured as one of the following forms: a patterned light-transmitting plate, a patterned light-transmitting film, a 3D free-form surface light-transmitting plate, a micro-nano texture light-transmitting film, a light diffraction light-transmitting film, etc.

[0044] According to the present invention, the dynamic light source 100 and the illuminated surface 410 are respectively arranged on both sides of the pattern light-transmitting layer 200, so that when the dynamic light source 100 moves along its effective moving trajectory, the light emitted by the dynamic light source 100 can pass through the light-transmitting area 210 of the pattern light-transmitting layer 200 to illuminate the pattern thereon, and the light of the illuminated pattern is projected onto the illuminated surface 410 to form a dynamic visual effect of moving close to or away from the observer and being larger near and smaller far away. It can be understood that the "larger near and smaller far away" referred to in this specification is based on the observer's position, that is, the projection pattern close to the observer is larger, and the projection pattern far away from the observer is smaller; if the light source position is used as a reference, the projection pattern close to the light source is smaller, and the projection pattern far away from the light source is larger. In addition, it can be understood that the effective movement trajectory of the dynamic light source 100 is periodic ("period" refers to the position cycle period that the dynamic light source 100 experiences from the starting point to the end point, rather than the time period), and the projection formed by the illuminated pattern projected onto the illuminated surface 410 monotonically increases (increases) or monotonically decreases (decreases) within a movement cycle of the dynamic light source 100.

[0045] Preferably, the angle between the effective moving trajectory of the dynamic light source 100 (i.e., the direction of the motion vector of the effective irradiation position) and the illuminated surface 410 is greater than 0° and less than 180°, that is, the effective moving trajectory of the dynamic light source 100 is not parallel to the illuminated surface 410; and / or, the angle between the patterned light-transmitting layer 200 (specifically, the plane direction of the flat patterned light-transmitting layer 200 perpendicular to its thickness direction) and the illuminated surface 410 is greater than 0° and less than 180°, that is, the patterned light-transmitting layer 200 is not parallel to the illuminated surface 410. More preferably, the effective moving trajectory of the dynamic light source 100 is not parallel to the illuminated surface 410, and the patterned light-transmitting layer 200 is not parallel to the illuminated surface 410. For example, in the first embodiment, the effective moving trajectory of the dynamic light source 100 is arranged to form an acute angle with the illuminated surface 410, and the patterned light-transmitting layer 200 is arranged to be substantially perpendicular to the illuminated surface 410.

[0046] like FIG. 2A to FIG. 2CAs shown in the changing process, when the dynamic light source 100 moves from right to left along its effective moving trajectory, that is, when a plurality of point light sources arranged linearly (for example, including the identified point light sources S1, S2, and S3) are lit in sequence from right to left, the light emitted by these point light sources can pass through the light-transmitting area 210 of the pattern light-transmitting layer 200, and the light of the illuminated pattern is projected onto the illuminated surface 410 to form a projection image that moves from top to bottom and gradually increases (for example, including the projection images PP1, PP2, and PP3 formed by the light emitted by the identified point light sources S1, S2, and S3, respectively), thereby forming a dynamic visual effect that moves close to the observer and becomes larger when near and smaller when far away. Similarly, when the dynamic light source 100 moves from left to right along its effective moving trajectory, that is, when a plurality of point light sources arranged linearly are lit in sequence from left to right (i.e., from S3 to S1), the light emitted by these point light sources can pass through the light-transmitting area 210 of the pattern light-transmitting layer 200, and enable the light of the illuminated pattern to be projected onto the illuminated surface 410 to form a projection image that moves from bottom to top and gradually decreases (i.e., from PP3 to PP1), thereby forming a dynamic visual effect that moves away from the observer and is larger when near and smaller when far.

[0047] Generally, when the human eye observes a moving object whose distance from the observer changes from far to near, the shape of the object seen by the observer is a gradually changing observation angle and enlarged effect because the observation position of the object relative to the observer is constantly changing and the distance is gradually decreasing. Conversely, when the human eye observes a moving object whose distance from the observer changes from near to far, the shape of the object seen by the observer is a gradually changing observation angle and enlarged effect because the observation position of the object relative to the observer is constantly changing and the distance is gradually increasing. Therefore, when the patterned light-transmitting layer 200 and the illuminated surface 410 are arranged according to the above requirements, and the dynamic light source 100 is arranged and moved according to the above requirements, as the position of the point light source changes, the pattern projected by the light of the point light source through the patterned light-transmitting layer 200 onto the illuminated surface 410 is displaced and the pattern is enlarged or reduced. This is in line with the visual law of the human eye observing an object from far to near or from near to far in nature, so that people can produce a "quasi-stereoscopic" visual effect of the light on the illuminated surface 410 moving toward or away from the observer.

[0048] The illuminated screen 400 may be a flat piece that is not completely transparent / semi-transparent but has a certain light transmittance. In this case, the dynamic light effect can be seen on both the side of the illuminated screen 400 close to the illuminated surface 410 and the side away from the illuminated surface 410. At this time, if the human eye is at the side of the illuminated screen 400 close to the illuminated surface 410, that is, at the first observation position 510 on the right side of the illuminated screen 400 as shown in the figure, the dynamic light source 100 and the patterned light-transmitting layer 200 may be an in-vehicle decoration component, and the illuminated surface 410 may belong to a certain in-vehicle component (such as an armrest, a dashboard, a floor etc.), the projection pattern on the illuminated surface 410 presents the indirect rhythmic light effect of the indirect projection atmosphere lamp to the observer; at this time, if the human eye observation position is on the side of the illuminated screen 400 away from the illuminated surface 410, that is, at the second observation position 520 on the left side of the illuminated screen 400 as shown in the figure, then the dynamic light source 100, the patterned light-transmitting layer 200, and the illuminated screen 400 can be an in-vehicle decorative component, and the side of the illuminated screen 400 away from the illuminated surface 410 is the outer surface of the decorative component, and the projection pattern on the illuminated surface 410 presents the direct rhythmic light effect of the back-transmitted projection atmosphere lamp to the observer. If the illuminated screen 400 is a non-light-transmitting component, the human eye observation position can only be on the side of the illuminated screen 400 close to the illuminated surface 410, and the projection pattern can only be used as an indirect rhythmic light effect.

[0049] If multiple groups of dynamic light sources 100 and / or multiple patterned light-transmitting layers 200 are arranged in the light projection area of ​​the same illuminated surface 410, the light passing through the patterned light-transmitting layer 200 and projected onto the illuminated surface 410 can form a dynamic visual effect formed by the superposition of multiple patterns. For example, the dynamic light effects of different groups of dynamic light sources 100 correspondingly irradiating the same or different patterned light-transmitting layers 200 and finally projected onto the illuminated surface 410 through transmission can be superimposed, and combined with different mobile software programming controls of different groups of dynamic light sources 100, a variety of superimposed dynamic light effects can be presented.

[0050] For specific physical effects, please refer to FIG. 10A to FIG. 10C As shown, in one movement cycle of the dynamic light source 100, each projection pattern moves toward the observer and the size gradually increases ( Fig. 10A Patterns 1 to 6 can be seen above. Fig. 10B The enlarged patterns 1 to 4 can be seen on the top. Fig. 10C It can be seen that patterns 1 to 3 become larger again).

[0051] In addition, the area that can be illuminated by the light emitted by each moving position of a single group of dynamic light sources 100 is limited. If the size of the illuminated surface 410 is large, only a part of the illuminated surface 410 will be illuminated. If the design intention of the product is to illuminate a specific area larger than that covered by a single group of dynamic light sources 100, multiple groups of dynamic light sources 100 can be arranged as needed to expand the illuminated area of ​​the illuminated surface 410 to meet the design intention of the product.

[0052] Second embodiment

[0053] like FIG. 3A to FIG. 3C As shown, the overall structure of the vehicle trim according to the second embodiment is similar to that of the first embodiment, and the similarities will not be repeated. The only difference is that, in the second embodiment, the patterned light-transmitting layer 200 is configured as a 3D free-form surface light-transmitting plate, which includes a light-transmitting area 210 with multiple patterns and a non-light-transmitting area 220.

[0054] like FIG. 3A to FIG. 3C As shown in the changing process, when the dynamic light source 100 moves from right to left along its effective moving trajectory, that is, when a plurality of point light sources arranged linearly (for example, including the identified point light sources S4, S5, and S6) are lit in sequence from right to left, the light emitted by these point light sources can pass through the light-transmitting area 210 of the pattern light-transmitting layer 200, and the light of the illuminated pattern is projected onto the illuminated surface 410 to form a projection image that moves from top to bottom and gradually increases (for example, including the projection images PP4, PP5, and PP6 formed by the light emitted by the identified point light sources S4, S5, and S6, respectively), thereby forming a dynamic visual effect that moves close to the observer and becomes larger when near and smaller when far away. Similarly, when the dynamic light source 100 moves from left to right along its effective moving trajectory, that is, when multiple point light sources arranged linearly are lit in sequence from left to right (i.e., from S6 to S4), the light emitted by these point light sources can pass through the light-transmitting area 210 of the pattern light-transmitting layer 200, and make the light of the illuminated pattern be projected onto the illuminated surface 410 to form a projection image that moves from bottom to top and gradually decreases (i.e., from PP6 to PP4), thereby forming a dynamic visual effect that moves away from the observer and is larger when near and smaller when far.

[0055] It is understandable that the figure only shows the dynamic light effect formed by a single pattern in the light-transmitting area 210 of the 3D free-form surface light-transmitting plate being illuminated by the dynamic light source 100 and projected onto the illuminated surface 410. In fact, each pattern in the light-transmitting area 210 of the 3D free-form surface light-transmitting plate can be illuminated by the dynamic light source 100 and projected onto the illuminated surface 410 to form a similar dynamic light effect, so that the observer can observe on the illuminated surface 410 a "smoke-like" overall dynamic light effect formed by the superposition of the dynamic light effects of each pattern. For specific physical effects, please refer to FIG. 11A to FIG. 11C As shown, within one movement cycle of the dynamic light source 100, each projection pattern (such as the marked area Z) moves toward the observer and gradually increases in size.

[0056] Third embodiment

[0057] like FIG. 4A to FIG. 4C As shown, the overall structure of the vehicle trim according to the third embodiment is similar to that of the first embodiment, and the similarities will not be described again. The only difference is that, in the third embodiment, the vehicle trim further includes a reflector 600, which is arranged between the dynamic light source 100 and the pattern light-transmitting layer 200 on the light propagation path, so as to reflect the light emitted by the dynamic light source 100 toward the pattern light-transmitting layer 200. The reflector 600 has a flat reflective surface, and the effective moving track of the dynamic light source 100, the reflective surface of the reflector 600, and the pattern light-transmitting layer 200 are arranged in parallel in pairs, and each of the effective moving track of the dynamic light source 100, the reflective surface of the reflector 600, and the pattern light-transmitting layer 200 is arranged to be substantially perpendicular to the illuminated surface 410.

[0058] like FIG. 4A to FIG. 4CAs shown in the changing process, when the dynamic light source 100 moves from right to left along its effective moving trajectory, that is, when a plurality of point light sources arranged linearly (for example, including the identified point light sources S7, S8, and S9) are lit in sequence from right to left, the light emitted by these point light sources can be reflected toward the patterned light-transmitting layer 200 via the reflector 600 to pass through the light-transmitting area 210 of the patterned light-transmitting layer 200, and the light of the illuminated pattern is projected onto the illuminated surface 410 to form a projection image that moves from top to bottom and gradually increases (for example, including the projection images PP7, PP8, and PP9 formed by the identified light emitted by the point light sources S7, S8, and S9, respectively), thereby forming a dynamic visual effect that moves close to the observer and becomes larger when near and smaller when far. Similarly, when the dynamic light source 100 moves from left to right along its effective moving trajectory, that is, when multiple point light sources arranged linearly are lit in sequence from left to right (i.e., from S9 to S7), the light emitted by these point light sources can be reflected toward the patterned light-transmitting layer 200 via the reflector 600 to pass through the light-transmitting area 210 of the patterned light-transmitting layer 200, and the light of the illuminated pattern is projected onto the illuminated surface 410 to form a projection image that moves from bottom to top and gradually decreases (i.e., from PP9 to PP7), thereby forming a dynamic visual effect that moves away from the observer and is larger when near and smaller when far.

[0059] It is understandable that the reflector 600 is particularly suitable for certain applications with a specific small space, so that it can be arranged to save space by reflecting light. The number, shape, arrangement angle and position of the reflector 600 can be determined according to the specific situation, and the present invention is not limited to this. For example, a plurality of reflectors 600 can be set in the vehicle trim as required. For another example, the reflector 600 can be arranged between the patterned light-transmitting layer 200 and the illuminated surface 410 on the light propagation path to reflect the light passing through the patterned light-transmitting layer 200 toward the illuminated surface 410.

[0060] Fourth embodiment

[0061] like FIG. 5A to FIG. 5C As shown, the overall structure of the vehicle trim according to the fourth embodiment is similar to that of the third embodiment, and the similarities will not be repeated, and the only difference is that the reflector 600 has a flat reflective surface, the effective moving trajectory of the dynamic light source 100 and the illuminated surface 410 are arranged to be parallel to each other, and the reflective surface of the reflector 600 is arranged to be roughly parallel to the effective moving trajectory of the dynamic light source 100 and the illuminated surface 410 (the effective moving trajectory of the dynamic light source 100 and the illuminated surface 410 are arranged in the vertical direction in the figure, and the reflective surface of the reflector 600 is slightly inclined relative to the vertical direction), and each of the effective moving trajectory of the dynamic light source 100, the reflective surface of the reflector 600 and the illuminated surface 410 are arranged to be roughly perpendicular to the patterned light-transmitting layer 200.

[0062] like FIG. 5A to FIG. 5C As shown in the changing process, when the dynamic light source 100 moves from bottom to top along its effective moving trajectory, that is, when a plurality of point light sources arranged linearly (for example, including the identified point light sources S10, S11, and S12) are lit up in sequence from bottom to top, the light emitted by these point light sources can be reflected toward the patterned light-transmitting layer 200 via the reflector 600 to pass through the light-transmitting area 210 of the patterned light-transmitting layer 200, and the light of the illuminated pattern is projected onto the illuminated surface 410 to form a projection image that moves from top to bottom and gradually increases (for example, including the projection images PP10, PP11, and PP12 formed by the identified light emitted by the point light sources S10, S11, and S12, respectively), thereby forming a dynamic visual effect that moves close to the observer and becomes larger when near and smaller when far. Similarly, when the dynamic light source 100 moves from top to bottom along its effective moving trajectory, that is, when a plurality of point light sources arranged linearly are lit in sequence from top to bottom (i.e., from S12 to S10), the light emitted by these point light sources can be reflected toward the patterned light-transmitting layer 200 via the reflector 600 to pass through the light-transmitting area 210 of the patterned light-transmitting layer 200, and the light of the illuminated pattern is projected onto the illuminated surface 410 to form a projection image that moves from bottom to top and gradually decreases (i.e., from PP12 to PP10), thereby forming a dynamic visual effect that moves away from the observer and is larger when near and smaller when far.

[0063] Fifth embodiment

[0064] like FIG. 6A to FIG. 6C As shown, the vehicle trim according to the fifth embodiment includes a dynamic light source 100, a flat patterned reflective layer 300 and a flat illuminated screen 400, wherein one side surface of the patterned reflective layer 300 forms a reflective surface, and one side surface of the illuminated screen 400 (i.e., the right side surface shown in the figure) forms an illuminated surface 410.

[0065] The dynamic light source 100 has a linear effective moving trajectory, that is, each irradiation position on the moving trajectory is an effective irradiation position. Here, the "effective irradiation position" refers to the corresponding position where the light emitted by the point light source at the position can irradiate the pattern reflective layer 300 to form a reflection and the reflection can form a projection pattern on the illuminated surface 410. That is to say, if the light emitted by the point light source at a certain position cannot irradiate the pattern reflective layer 300 or cannot be reflected by the pattern reflective layer 300 to form a projection pattern on the illuminated surface 410, then the position does not belong to the "effective irradiation position" here. It can be understood that the light source form and movement form of the dynamic light source 100 can be of many types, and the present invention does not limit this. In the illustrated embodiment, the dynamic light source 100 includes a plurality of point light sources that are linearly arranged and controlled to light up in sequence, that is, the movement of the point light source position can be realized by software pipeline programming of these linearly arranged point light sources. That is, in the illustrated embodiment, the moving trajectory of the dynamic light source 100 refers to the connecting line of the positions of the point light sources that are lit up in sequence (i.e., the lighting trajectory), rather than the motion trajectory of mechanical movement. According to other implementation variations, the dynamic light source 100 may also be, for example, a single point light source driven by a driving mechanism to move along its movement trajectory.

[0066] The patterned reflective layer 300 at least includes a reflective area 310 with a pattern / texture. In the first embodiment, the patterned reflective layer 300 is configured as a patterned reflective plate, which includes a reflective area 310 with a pattern and a non-reflective area 320. The patterned reflective layer 300 can have many types of structural forms, as long as it has at least a reflective area and the reflective area forms a reflective pattern with a specific design intention, and the present invention does not limit this. According to other implementation variations, the patterned reflective layer 300 can also be configured as one of the following forms: a patterned reflective film, a 3D free-form surface reflective plate, a micro-nano textured reflective film, a light diffraction reflective film, etc.

[0067] According to the present invention, when the dynamic light source 100 moves along its effective moving trajectory, the light emitted by the dynamic light source 100 can be irradiated on the reflective area 310 of the pattern reflective layer 300 to illuminate the pattern thereon, and the light of the illuminated pattern is reflected by the reflective area 310 and projected onto the illuminated surface 410 to form a dynamic visual effect of moving toward or away from the observer and being larger near and smaller far away. It can be understood that the effective moving trajectory of the dynamic light source 100 is periodic ("period" refers to the position cycle of the dynamic light source 100 from the starting point to the end point, not the time cycle), and the projection formed by the illuminated pattern projected onto the illuminated surface 410 monotonically increases (increases) or monotonically decreases (decreases) within a moving cycle of the dynamic light source 100.

[0068] The angle between the effective moving track of the dynamic light source 100 (i.e., the direction of the motion vector of the effective irradiation position) and the illuminated surface 410 is greater than or equal to 0° and less than or equal to 180°, that is, the effective moving track of the dynamic light source 100 can be arranged to be parallel or non-parallel to the illuminated surface 410; and / or, the angle between the patterned reflective layer 300 (specifically, the direction of the reflective surface of the flat patterned reflective layer 300) and the illuminated surface 410 is greater than or equal to 0° and less than or equal to 180°, that is, the patterned reflective layer 300 can be arranged to be parallel or non-parallel to the illuminated surface 410. For example, in the fifth embodiment, the effective moving track of the dynamic light source 100 is arranged to form an acute angle with the illuminated surface 410, and the patterned reflective layer 300 is arranged to form an obtuse angle with the illuminated surface 410.

[0069] like FIG. 6A to FIG. 6C As shown in the changing process, when the dynamic light source 100 moves from right to left along its effective moving trajectory, that is, when a plurality of point light sources arranged linearly (for example, including the identified point light sources S13, S14, and S15) are lit in sequence from right to left, the light emitted by these point light sources can be irradiated on the reflective area 310 of the pattern reflective layer 300, and the light of the illuminated pattern is reflected by the reflective area 310 and projected onto the illuminated surface 410 to form a projection image that moves from top to bottom and gradually increases (for example, including the projection images PP13, PP14, and PP15 formed by the identified light emitted by the point light sources S13, S14, and S15, respectively), thereby forming a dynamic visual effect that moves close to the observer and becomes larger when near and smaller when far away. Similarly, when the dynamic light source 100 moves from left to right along its effective moving trajectory, that is, when a plurality of point light sources arranged linearly are lit in sequence from left to right (i.e., from S15 to S13), the light emitted by these point light sources can be irradiated on the reflective area 310 of the pattern reflective layer 300, and the light of the illuminated pattern is reflected by the reflective area 310 and projected onto the illuminated surface 410 to form a projection image that moves from bottom to top and gradually decreases (i.e., from PP15 to PP13), thereby forming a dynamic visual effect that moves away from the observer and is larger when near and smaller when far.

[0070] Generally, when the human eye observes a moving object whose distance from the observer changes from far to near, the shape of the object seen by the observer is a gradually changing observation angle and enlarged effect because the observation position of the object relative to the observer is constantly changing and the distance is gradually decreasing. On the contrary, when the human eye observes a moving object whose distance from the observer changes from near to far, the shape of the object seen by the observer is a gradually changing observation angle and enlarged effect because the observation position of the object relative to the observer is constantly changing and the distance is gradually increasing. Therefore, when the patterned reflective layer 300 and the illuminated surface 410 are arranged according to the above requirements, and the dynamic light source 100 is arranged and moved according to the above requirements, as the position of the point light source changes, the pattern projected on the illuminated surface 410 by the light of the point light source irradiating the patterned reflective layer 300 and reflected by the light source is displaced and enlarged or reduced at the same time, which conforms to the visual law of the human eye observing an object from far to near or from near to far in nature, so that people can produce a "quasi-stereoscopic" visual effect of the light on the illuminated surface 410 moving toward or away from the observer.

[0071] The illuminated screen 400 may be a flat piece that is not completely transparent / semi-transparent but has a certain light transmittance. In this case, the dynamic light effect can be seen on both the side of the illuminated screen 400 close to the illuminated surface 410 and the side away from the illuminated surface 410. At this time, if the human eye is at the side of the illuminated screen 400 close to the illuminated surface 410, that is, at the first observation position 510 on the right side of the illuminated screen 400 as shown in the figure, the dynamic light source 100 and the patterned reflective layer 300 may be an in-vehicle decoration component, and the illuminated surface 410 may belong to a certain in-vehicle component (such as an armrest, a dashboard, a floor etc.), the projection pattern on the illuminated surface 410 presents the indirect rhythmic light effect of the indirect projection atmosphere lamp to the observer; at this time, if the human eye observation position is on the side of the illuminated screen 400 away from the illuminated surface 410, that is, at the second observation position 520 on the left side of the illuminated screen 400 as shown in the figure, then the dynamic light source 100, the patterned reflective layer 300, and the illuminated screen 400 can be an in-vehicle decorative component, and the side of the illuminated screen 400 away from the illuminated surface 410 is the outer surface of the decorative component, and the projection pattern on the illuminated surface 410 presents the direct rhythmic light effect of the back-transparent projection atmosphere lamp to the observer. If the illuminated screen 400 is a non-light-transmitting component, the human eye observation position can only be on the side of the illuminated screen 400 close to the illuminated surface 410, and the projection pattern can only be used as an indirect rhythmic light effect.

[0072] If multiple groups of dynamic light sources 100 and / or multiple patterned reflective layers 300 are arranged in the light projection area of ​​the same illuminated surface 410, the light reflected by the patterned reflective layer 300 onto the illuminated surface 410 can form a dynamic visual effect formed by the superposition of multiple patterns. For example, the dynamic light effects of different groups of dynamic light sources 100 correspondingly irradiating the same or different patterned reflective layers 300 and finally projected onto the illuminated surface 410 through reflection can be superimposed, and combined with different mobile software programming controls of different groups of dynamic light sources 100, a variety of superimposed dynamic light effects can be presented.

[0073] In addition, the area that can be illuminated by the light emitted by each moving position of a single group of dynamic light sources 100 is limited. If the size of the illuminated surface 410 is large, only a part of the illuminated surface 410 will be illuminated. If the design intention of the product is to illuminate a specific area larger than that covered by a single group of dynamic light sources 100, multiple groups of dynamic light sources 100 can be arranged as needed to expand the illuminated area of ​​the illuminated surface 410 to meet the design intention of the product.

[0074] Sixth embodiment

[0075] like FIG. 7A to FIG. 7C As shown, the overall structure of the vehicle trim according to the sixth embodiment is similar to that of the fifth embodiment, and the similarities will not be described again. The only difference is that, in the sixth embodiment, the vehicle trim further includes a reflector 600, which is arranged between the patterned reflective layer 300 and the illuminated surface 410 on the light propagation path, so as to reflect the light reflected by the patterned reflective layer 300 toward the illuminated surface 410. The reflector 600 has a flat reflective surface, and the effective moving track of the dynamic light source 100, the patterned reflective layer 300, and the reflective surface of the reflector 600 are arranged to be parallel to each other, and each of the effective moving track of the dynamic light source 100, the patterned reflective layer 300, and the reflective surface of the reflector 600 is arranged to be perpendicular to the illuminated surface 410.

[0076] like FIG. 7A to FIG. 7CAs shown in the changing process, when the dynamic light source 100 moves from right to left along its effective moving trajectory, that is, when a plurality of point light sources arranged linearly (for example, including the identified point light sources S16, S17, and S18) are lit in sequence from right to left, the light emitted by these point light sources can be irradiated on the reflective area 310 of the pattern reflective layer 300, and the light of the illuminated pattern is reflected by the reflective area 310 and then reflected again by the reflector 600, and finally projected onto the illuminated surface 410 to form a projection image that moves from top to bottom and gradually increases (for example, including the projection images PP16, PP17, and PP18 formed by the light emitted by the identified point light sources S16, S17, and S18, respectively), thereby forming a dynamic visual effect that moves close to the observer and is larger when near and smaller when far. Similarly, when the dynamic light source 100 moves from left to right along its effective moving trajectory, that is, when a plurality of point light sources arranged linearly are lit in sequence from left to right (i.e., from S18 to S16), the light emitted by these point light sources can be irradiated on the reflective area 310 of the pattern reflective layer 300, and the light of the illuminated pattern is reflected by the reflective area 310 and then reflected again by the reflector 600, and finally projected onto the illuminated surface 410 to form a projection image that moves from bottom to top and gradually decreases (i.e., from PP18 to PP16), thereby forming a dynamic visual effect of moving away from the observer and being larger when near and smaller when far.

[0077] It is understandable that the reflector 600 is particularly suitable for certain applications with a specific small space, so that it can be arranged to save space by reflecting light. The number, shape, arrangement angle and position of the reflector 600 can be determined according to the specific situation, and the present invention is not limited to this. For example, a plurality of reflectors 600 can be set in the vehicle trim as required. For another example, the reflector 600 can be arranged between the dynamic light source 100 and the patterned reflective layer 300 on the light propagation path to reflect the light emitted by the dynamic light source 100 toward the patterned reflective layer 300.

[0078] Seventh embodiment

[0079] like FIG. 8A to FIG. 8C As shown, the overall structure of the vehicle trim according to the seventh embodiment is similar to that of the sixth embodiment, and the similarities will not be repeated, and the only difference is that the reflector 600 has a flat reflective surface, the effective moving trajectory of the dynamic light source 100, the patterned reflective layer 300 and the illuminated surface 410 are arranged parallel to each other, and the reflective surface of the reflector 600 is arranged to be roughly parallel to the effective moving trajectory of the dynamic light source 100, the patterned reflective layer 300 and the illuminated surface 410 (the effective moving trajectory of the dynamic light source 100, the patterned reflective layer 300 and the illuminated surface 410 in the figure are arranged along the vertical direction, and the reflective surface of the reflector 600 is slightly inclined relative to the vertical direction).

[0080] like FIG. 8A to FIG. 8C As shown in the changing process, when the dynamic light source 100 moves from bottom to top along its effective moving trajectory, that is, when a plurality of point light sources arranged linearly (for example, including the identified point light sources S19, S20, and S21) are lit up in sequence from bottom to top, the light emitted by these point light sources can be irradiated on the reflective area 310 of the pattern reflective layer 300, and the light of the illuminated pattern is reflected by the reflective area 310 and then reflected again by the reflector 600, and finally projected onto the illuminated surface 410 to form a projection image that moves from top to bottom and gradually increases (for example, including the projection images PP19, PP20, and PP21 formed by the light emitted by the identified point light sources S19, S20, and S21, respectively), thereby forming a dynamic visual effect that moves close to the observer and is larger when near and smaller when far. Similarly, when the dynamic light source 100 moves from top to bottom along its effective moving trajectory, that is, when a plurality of point light sources arranged linearly are lit in sequence from top to bottom (i.e., from S21 to S19), the light emitted by these point light sources can be irradiated on the reflective area 310 of the pattern reflective layer 300, and the light of the illuminated pattern is reflected by the reflective area 310 and then reflected again by the reflector 600, and finally projected onto the illuminated surface 410 to form a projection image that moves from bottom to top and gradually decreases (i.e., from PP21 to PP19), thereby forming a dynamic visual effect of moving away from the observer and being larger when near and smaller when far.

[0081] Eighth embodiment

[0082] 9A to 9D The eighth embodiment shown is a physical application of the vehicle trim according to the present invention on a vehicle door. 9A to 9DAs shown, the vehicle trim includes an upper decorative plate 700, a two-color injection-molded bracket 800 arranged below the upper decorative plate 700, and a center-embedded decorative plate 900 arranged below the bracket 800, and a side surface of the center-embedded decorative plate 900 (i.e., the right side surface in the figure) forms an illuminated surface 410. The dynamic light source 100 is arranged in a cavity defined by the upper decorative plate 700 and the bracket 800, and includes a plurality of point light sources that are linearly arranged and controlled to light up in sequence, that is, the position of the point light source can be moved by performing software pipeline programming on these linearly arranged point light sources. The bracket 800 is formed by two-color injection molding of a non-light-transmitting material 810 (e.g., ABS (acrylonitrile-butadiene-styrene plastic)) and a light-transmitting material 820 (e.g., PC (polycarbonate)). The light-transmitting material 820 is positioned below the dynamic light source 100, and the pattern light-transmitting layer 200 (here, a pattern light-transmitting film) is combined with the bottom surface of the light-transmitting material 820, for example, by IML (in-mold molding). The substrate of the light-transmitting film is purely transparent, and a non-light-transmitting ink is screen-printed on a part of the substrate by screen printing. The area covered with the non-light-transmitting ink by screen printing is the non-light-transmitting area 220, and the area not screen-printed with the non-light-transmitting ink forms a light-transmitting area 210 with a light-transmitting pattern. There are actually multiple light-transmitting patterns on the light-transmitting film shown in the figure, and the figure only shows the dynamic change process of the projection pattern of one of the light-transmitting patterns.

[0083] like 9A to 9C As shown in the changing process, when the dynamic light source 100 moves from right to left along its effective moving trajectory, that is, when a plurality of point light sources arranged linearly (for example, including the identified point light sources S22, S23, and S24) are lit in sequence from right to left, the light emitted by these point light sources can pass through the light-transmitting area 210 of the pattern light-transmitting layer 200, and the light of the illuminated pattern is projected onto the illuminated surface 410 to form a projection image that moves from top to bottom and gradually increases (for example, including the projection images PP22, PP23, and PP24 formed by the identified light emitted by the point light sources S22, S23, and S24, respectively), thereby forming a dynamic visual effect that moves close to the observer and becomes larger when near and smaller when far away. Similarly, when the dynamic light source 100 moves from left to right along its effective moving trajectory, that is, when a plurality of point light sources arranged linearly are lit in sequence from left to right (i.e., from S24 to S22), the light emitted by these point light sources can pass through the light-transmitting area 210 of the pattern light-transmitting layer 200, and enable the light of the illuminated pattern to be projected onto the illuminated surface 410 to form a projection image that moves from bottom to top and gradually decreases (i.e., from PP24 to PP22), thereby forming a dynamic visual effect that moves away from the observer and is larger when near and smaller when far.
