Description

Vehicle trim Technical Field

[0001] This invention relates to the field of vehicle component technology. More specifically, this invention relates to a vehicle trim piece. Background Technology

[0002] Currently, the lighting effects of indirect or backlit projection ambient lighting used as interior and exterior trim in vehicles are typically 2D. To enhance the premium feel of vehicle trim, there is a desire to introduce an indirect or backlit projection ambient lighting system with a "near-three-dimensional" dynamic visual effect. This necessitates further design of the key components for constructing such a projection ambient lighting system, as well as their corresponding structures, schemes, and arrangement relationships. Summary of the Invention

[0003] The purpose of this invention is to enhance the lighting effect of indirect or backlit ambient lighting in vehicles from a 2D (two-dimensional) visual effect to a dynamic 3D (three-dimensional) visual effect. More specifically, the purpose of this invention is to provide a vehicle trim piece that provides a "near-three-dimensional" dynamic imaging simulation pattern / texture visual effect that moves closer to or further away from the observer and is larger when closer and smaller when farther away.

[0004] To this end, a first aspect of the present invention provides a vehicle trim piece including a dynamic light source, a patterned light-transmitting layer, and an illuminated surface, wherein the dynamic light source has a linear movement trajectory, and the patterned light-transmitting layer includes a light-transmitting area with a pattern, wherein the vehicle trim piece is configured such that, as the dynamic light source moves along the movement 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 create a dynamic visual effect of movement towards or away from the observer and of objects appearing larger when closer and smaller when farther away.

[0005] Based on the above-described technical concept, the present invention may further include any one or more of the following optional forms.

[0006] In some alternative 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 alternative forms, the movement trajectory of the dynamic light source forms an acute angle with the illuminated surface, and the patterned light-transmitting layer is approximately perpendicular to the illuminated surface.

[0008] In some alternative forms, the patterned light-transmitting layer is configured as one of the following: a patterned light-transmitting plate, a patterned perforated plate, a patterned light-transmitting film, a 3D freeform surface light-transmitting plate, a micro-nano textured light-transmitting film, or a light diffraction light-transmitting film.

[0009] In some alternative forms, the vehicle trim also includes at least one reflective surface configured to reflect light emitted by the dynamic light source toward the patterned light-transmitting layer, or to reflect light passing through the patterned light-transmitting layer toward the illuminated surface.

[0010] In some alternative configurations, the movement trajectory of the dynamic light source, the reflective surface, and the patterned light-transmitting layer are generally parallel to each other and all are generally perpendicular to the illuminated surface.

[0011] In some alternative configurations, the movement trajectory of the dynamic light source, the illuminated surface, and the reflecting surface are approximately parallel to each other and are all approximately perpendicular to the patterned light-transmitting layer.

[0012] In some alternative forms, the vehicle trim includes multiple sets of dynamic light sources and / or multiple patterned light-transmitting layers, such that light projected onto the illuminated surface through the patterned light-transmitting layers forms a dynamic visual effect composed of multiple superimposed patterns.

[0013] A second aspect of the present invention provides a vehicle trim piece including a dynamic light source, a patterned reflective layer, and an illuminated surface, wherein the dynamic light source has a linear movement trajectory, and the patterned reflective layer includes a reflective area with a pattern, wherein the vehicle trim piece is configured such that, as the dynamic light source moves along the movement trajectory, light emitted by the dynamic light source illuminates the reflective area to illuminate the pattern, and after reflection through the reflective area, the pattern is projected onto the illuminated surface to form a dynamic visual effect of moving closer to or further away from the observer and appearing larger when closer and smaller when farther away.

[0014] In some alternative 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°.

[0015] In some alternative forms, the moving trajectory of the dynamic light source forms an acute angle with the illuminated surface, and the patterned reflective layer forms an obtuse angle with the illuminated surface.

[0016] In some alternative forms, the patterned reflective layer is configured as one of the following: a patterned reflector, a patterned reflective film, a 3D freeform reflector, a micro-nano textured reflective film, or a light diffraction reflective film.

[0017] In some alternative forms, the vehicle trim also includes at least one reflective surface configured to reflect light emitted by the dynamic light source toward the patterned reflective layer, or to reflect light reflected via the patterned reflective layer toward the illuminated surface.

[0018] In some alternative configurations, the movement trajectory of the dynamic light source, the patterned reflective layer, and the reflective surface are generally parallel to each other and generally perpendicular to the illuminated surface.

[0019] In some alternative configurations, the movement trajectory of the dynamic light source, the patterned reflective layer, the illuminated surface, and the reflective surface are generally parallel to each other.

[0020] In some alternative forms, the vehicle trim includes multiple sets of dynamic light sources and / or multiple patterned reflective layers, such that light reflected from the patterned reflective layers onto the illuminated surface forms a dynamic visual effect composed of multiple superimposed patterns.

[0021] In some alternative forms, the dynamic light source comprises a plurality of point light sources arranged linearly and controlled to illuminate sequentially, or the dynamic light source is a single point light source driven by a drive mechanism to move along the movement trajectory.

[0022] In some alternative forms, the movement trajectory of the dynamic light source is periodic, and the projection of the pattern onto the illuminated surface monotonically increases or decreases within one movement cycle of the dynamic light source.

[0023] In some alternative forms, the vehicle trim includes a flat, semi-transparent or non-transparent illuminated screen, with one side surface of the illuminated screen forming the illuminated surface.

[0024] In some alternative forms, the vehicle trim is applied to at least one of the following vehicle components: front bumper, hood, fender, side door, side panel, tailgate, rear bumper, dashboard, door inner panel, sub-dashboard, floor, interior headliner, headrest, and seat back.

[0025] Compared to existing technologies, the vehicle trim according to the present invention has several beneficial technical effects, especially: the vehicle trim utilizes a dynamic light source and a layer with a translucent or reflective pattern to illuminate the surface with patterned light. The pattern / texture is always illuminated by the light source and forms a projected pattern on the surface. By changing the position of the light source, the projected pattern on the surface undergoes continuous displacement and dimensional stretching / compression. Since the process of pattern displacement and dimensional stretching / compression conforms to the human eye's visual observation law of moving objects from far to near or from near to far, it can create a dynamic light effect that moves the light towards / away from the observer, thereby enhancing the user's sensory experience.

[0042] The elements in the accompanying drawings are shown for simplicity and clarity and are not necessarily drawn to precise scale or shape. It should be understood that the drawings are not only used for explanation and illustration of the invention, but also, where necessary, to limit the invention. Detailed Implementation

[0043] 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 particular ways of implementing and using the invention, and are not intended to limit the scope of the invention.

[0044] In this article, the directional terms such as "up," "down," "left," and "right" used to describe the position of structures are not absolute but relative. For example, these directional terms are appropriate when the components are arranged as shown in the figure, but they should be changed accordingly when the positions of the components in the figure change.

[0045] As shown in Figure 1A, the vehicle trim according to the present invention can be disposed on the exterior of the vehicle, for example, it can be applied to at least one of the following vehicle components: front bumper FB with grille, engine hood HD, fender FD, side door SD, side panel SB, tailgate TG, rear bumper RB, etc. As shown in Figures 1B to 1D, the vehicle trim according to the present invention can also be disposed on the interior of the vehicle, for example, it can be applied to at least one of the following vehicle components: instrument panel IP, door inner panel DP, sub-instrument panel CS, floor FL, interior roof CL, headrest HR, seat back SK, etc.

[0046] First Embodiment

[0047] As shown in Figures 2A to 2C, 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, wherein one side surface of the illuminated screen 400 (i.e., the right side surface shown in the figure) forms an illuminated surface 410.

[0048] The dynamic light source 100 has a linear effective movement trajectory, meaning that each illumination position on this trajectory is an effective illumination position. Here, an "effective illumination position" refers to the corresponding position where the light emitted by the point light source can penetrate the patterned light-transmitting layer 200 and form a projected pattern on the illuminated surface 410. That is, if the light emitted by the point light source at a certain position cannot penetrate the patterned light-transmitting layer 200 or cannot form a projected pattern on the illuminated surface 410, then that position does not belong to the "effective illumination position" here. It is 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 them. In the illustrated embodiment, the dynamic light source 100 includes multiple point light sources arranged linearly and controlled to be lit sequentially, that is, the movement of the point light source positions can be achieved by software pipeline programming of these linearly arranged point light sources. In other words, in the illustrated embodiment, the movement trajectory of the dynamic light source 100 refers to the line connecting the positions of the sequentially lit point light sources (i.e., the lighting trajectory), rather than the movement trajectory of mechanical motion. According to other implementation variations, the dynamic light source 100 may also be a single point light source driven by a drive mechanism to move along its movement trajectory.

[0049] The patterned light-transmitting layer 200 includes at least a light-transmitting area 210 with a pattern / texture. In this first embodiment, the patterned light-transmitting layer 200 is configured as a patterned cutout plate, which includes a light-transmitting area 210 with a cutout pattern and a non-light-transmitting area 220. The patterned light-transmitting layer 200 can have many different structural forms, as long as it has at least a light-transmitting area and the light-transmitting area forms a light-transmitting pattern with a specific design intent. This invention does not limit this. According to other embodiments, 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 freeform surface light-transmitting plate, a micro / nano textured light-transmitting film, a light diffraction light-transmitting film, etc.

[0050] 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 from the illuminated pattern is projected onto the illuminated surface 410 to form a dynamic visual effect of the pattern moving closer to or further away from the observer and appearing larger when closer and smaller when farther away. It is understood that the term "larger when closer and smaller when farther away" in this specification is based on the observer's position, that is, the projected pattern closer to the observer is larger, and the projected pattern farther from the observer is smaller; if the light source position is used as the reference, then the projected pattern closer to the light source is smaller, and the projected pattern farther from the light source is larger. Furthermore, it is understood that the effective movement 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 ending point, rather than the time cycle), and the projection of the illuminated pattern onto the illuminated surface 410 monotonically increases (increases) or monotonically decreases (decreases) within one movement cycle of the dynamic light source 100.

[0051] Preferably, the effective movement trajectory of the dynamic light source 100 (i.e., the direction of the motion vector of the effective illumination position) and the illuminated surface 410 form an angle greater than 0° and less than 180°, meaning the effective movement 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 planar 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°, meaning the patterned light-transmitting layer 200 is not parallel to the illuminated surface 410. More preferably, the effective movement 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 this first embodiment, the effective movement 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 approximately perpendicular to the illuminated surface 410.

[0052] As shown in the process from Figure 2A to Figure 2C, when the dynamic light source 100 moves from right to left along its effective movement trajectory, that is, when multiple point light sources arranged linearly (such as the marked point light sources S1, S2, and S3) are lit sequentially 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 in size (such as the marked projection images PP1, PP2, and PP3 formed by the light emitted by point light sources S1, S2, and S3 respectively). This creates a dynamic visual effect that moves closer to the observer and appears larger when closer and smaller when farther away. Similarly, when the dynamic light source 100 moves from left to right along its effective movement trajectory, that is, when multiple point light sources arranged linearly are lit sequentially 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 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 in size (i.e. from PP3 to PP1), thereby creating a dynamic visual effect that moves away from the observer and appears larger when closer and smaller when farther away.

[0053] Normally, when the human eye observes a moving object that is getting closer to the observer, the object's position relative to the observer is constantly changing, and the distance is gradually decreasing. Therefore, the shape of the object appears magnified as the viewing angle changes. Conversely, when the human eye observes a moving object that is getting farther away from the observer, the object's position 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 as described above, and the dynamic light source 100 is arranged and moved as described above, as the position of the point light source changes, the pattern projected onto the illuminated surface 410 by the light from the point light source passing through the patterned light-transmitting layer 200 shifts, and the pattern magnifies or shrinks. This conforms to the visual law of the human eye observing an object from far to near or from near to far in nature, thus creating a "near-three-dimensional" visual effect where the light on the illuminated surface 410 appears to move closer to or away from the observer.

[0054] The illuminated screen 400 can be configured as a flat component that is not completely transparent / semi-transparent but has a certain light transmittance. In this case, dynamic light effects can be seen on both the side of the illuminated screen 400 near the illuminated surface 410 and the side away from the illuminated surface 410. If the human eye is observing from the side of the illuminated screen 400 near the illuminated surface 410, i.e., at the first observation position 510 on the right side of the illuminated screen 400 as shown in the figure, then the dynamic light source 100 and the patterned light-transmitting layer 200 can be an interior decoration component, and the illuminated surface 410 can belong to a certain interior component (such as armrest, dashboard, floor). (etc.), the projected pattern on the illuminated surface 410 presents an indirect rhythmic lighting effect to the observer, similar to an indirect projection ambient light. If the observer's position is on the side of the illuminated screen 400 away from the illuminated surface 410, i.e., at the second observation position 520 on the left side of the illuminated screen 400 as shown in the diagram, then the dynamic light source 100, the pattern light-transmitting layer 200, and the illuminated screen 400 can be an interior decoration component. The side of the illuminated screen 400 away from the illuminated surface 410 is the outer surface of this decoration component, and the projected pattern on the illuminated surface 410 presents a direct rhythmic lighting effect to the observer, similar to a backlit projection ambient light. However, if the illuminated screen 400 is a non-transparent component, then the observer's position can only be on the side of the illuminated screen 400 closer to the illuminated surface 410, and the projected pattern can only serve as an indirect rhythmic lighting effect.

[0055] If multiple sets 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 projected onto the illuminated surface 410 through the patterned light-transmitting layers 200 can form a dynamic visual effect composed of multiple superimposed patterns. For example, the dynamic light effects of different sets of dynamic light sources 100 correspondingly illuminating the same or different patterned light-transmitting layers 200 and finally projected onto the illuminated surface 410 through transmission can be superimposed. Combined with different moving software programming control of different sets of dynamic light sources 100, varied and superimposed dynamic light effects can be presented.

[0056] The specific physical effect can be seen in Figures 10A to 10C. That is, within one moving cycle of the dynamic light source 100, each projected pattern moves toward the observer and its size gradually increases (patterns 1 to 6 can be seen in Figure 10A, patterns 1 to 4 can be seen enlarged in Figure 10B, and patterns 1 to 3 can be seen enlarged again in Figure 10C).

[0057] Furthermore, the area illuminated by the light from each moving position of a single dynamic light source 100 is limited. If the size of the illuminated surface 410 is large, only a localized area of ​​the illuminated surface 410 will be illuminated. If the product is designed to illuminate a specific area larger than that covered by a single dynamic light source 100, multiple dynamic light sources 100 can be arranged as needed to expand the illumination range of the illuminated surface 410 and meet the product's design intent.

[0058] Second Embodiment

[0059] As shown in Figures 3A to 3C, the overall structure of the vehicle trim according to the second embodiment is similar to that of the first embodiment. The similarities will not be described again. The only difference is that in this second embodiment, the patterned light-transmitting layer 200 is set as a 3D freeform light-transmitting plate, which includes a light-transmitting area 210 with multiple patterns and a non-light-transmitting area 220.

[0060] As shown in Figures 3A to 3C, when the dynamic light source 100 moves from right to left along its effective movement trajectory, that is, when multiple point light sources arranged linearly (such as the identified point light sources S4, S5, and S6) are lit sequentially 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 in size (such as the identified projection images PP4, PP5, and PP6 formed by the light emitted by point light sources S4, S5, and S6, respectively). This creates a dynamic visual effect that moves closer to the observer and appears larger when closer and smaller when farther away. Similarly, when the dynamic light source 100 moves from left to right along its effective movement trajectory, that is, when multiple point light sources arranged linearly are lit sequentially 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 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 in size (i.e. from PP6 to PP4), thereby creating a dynamic visual effect that moves away from the observer and appears larger when closer and smaller when farther away.

[0061] It is understood that the figure only shows the dynamic light effect formed by a single pattern in the light-transmitting area 210 of the 3D freeform light-transmitting panel being illuminated by the dynamic light source 100 and projected onto the illuminated surface 410. In reality, each pattern in the light-transmitting area 210 of the 3D freeform light-transmitting panel can be illuminated by the dynamic light source 100 and projected onto the illuminated surface 410 to form a similar dynamic light effect. The observer can thus observe a "smoke-like" overall dynamic light effect on the illuminated surface 410 formed by the superposition of the dynamic light effects of each pattern. The specific physical effect can be seen in Figures 11A to 11C, that is, within one moving cycle of the dynamic light source 100, each projected pattern (e.g., the marked area Z) moves toward the observer and its size gradually increases.

[0062] Third Embodiment

[0063] As shown in Figures 4A to 4C, 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 repeated. The only difference is that in this third embodiment, the vehicle trim also includes a reflector 600, which is arranged between the dynamic light source 100 and the patterned light-transmitting layer 200 in the light propagation path to reflect the light emitted by the dynamic light source 100 toward the patterned light-transmitting layer 200. The reflector 600 has a flat reflective surface, and the effective movement trajectory of the dynamic light source 100, the reflective surface of the reflector 600, and the patterned light-transmitting layer 200 are arranged in pairs that are approximately parallel. Furthermore, each of the dynamic light source 100, the reflective surface of the reflector 600, and the patterned light-transmitting layer 200 is arranged approximately perpendicular to the illuminated surface 410.

[0064] As shown in Figures 4A to 4C, when the dynamic light source 100 moves from right to left along its effective movement trajectory, that is, when multiple point light sources arranged linearly (such as the identified point light sources S7, S8, and S9) are lit sequentially from right to left, the light emitted by these point light sources can be reflected by the reflector 600 toward the pattern light-transmitting layer 200 to 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 in size (such as the projection images PP7, PP8, and PP9 formed by the light emitted by the identified point light sources S7, S8, and S9, respectively). This creates a dynamic visual effect that moves closer to the observer and appears larger when closer and smaller when farther away. Similarly, when the dynamic light source 100 moves from left to right along its effective movement trajectory, that is, when multiple point light sources arranged linearly are lit sequentially from left to right (i.e. from S9 to S7), the light emitted by these point light sources can be reflected by the reflector 600 toward the pattern light-transmitting layer 200 to 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 bottom to top and gradually decreases in size (i.e. from PP9 to PP7), thereby creating a dynamic visual effect that moves away from the observer and appears larger when closer and smaller when farther away.

[0065] It is understood that the reflector 600 is particularly suitable for certain applications with limited space, as it can save space through light reflection. The number, shape, arrangement angle, and position of the reflector 600 can be determined according to specific circumstances, and the present invention does not limit this. For example, multiple reflectors 600 can be provided in the vehicle trim as needed. Alternatively, the reflector 600 can be arranged between the patterned light-transmitting layer 200 and the illuminated surface 410 along the light propagation path to reflect light passing through the patterned light-transmitting layer 200 toward the illuminated surface 410.

[0066] Fourth embodiment

[0067] As shown in Figures 5A to 5C, the overall structure of the vehicle trim according to the fourth embodiment is similar to that of the third embodiment. The similarities will not be described again. The only difference is that the reflector 600 has a flat reflective surface, the effective movement trajectory of the dynamic light source 100 and the illuminated surface 410 are arranged parallel to each other, and the reflective surface of the reflector 600 is arranged to be approximately parallel to the effective movement trajectory of the dynamic light source 100 and the illuminated surface 410 (in the figure, the effective movement trajectory of the dynamic light source 100 and the illuminated surface 410 are arranged in the vertical direction, and the reflective surface of the reflector 600 is slightly inclined relative to the vertical direction). Furthermore, each of the effective movement trajectory of the dynamic light source 100, the reflective surface of the reflector 600 and the illuminated surface 410 is arranged to be approximately perpendicular to the patterned light-transmitting layer 200.

[0068] As shown in the process from Figure 5A to Figure 5C, when the dynamic light source 100 moves from bottom to top along its effective movement trajectory, that is, when multiple point light sources arranged linearly (such as the identified point light sources S10, S11, and S12) are lit sequentially from bottom to top, the light emitted by these point light sources can be reflected by the reflector 600 toward the pattern light-transmitting layer 200 to 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 in size (such as the projection images PP10, PP11, and PP12 formed by the light emitted by the identified point light sources S10, S11, and S12, respectively). This creates a dynamic visual effect that moves closer to the observer and appears larger when closer and smaller when farther away. Similarly, when the dynamic light source 100 moves from top to bottom along its effective movement trajectory, that is, when multiple point light sources arranged linearly are lit sequentially from top to bottom (i.e. from S12 to S10), the light emitted by these point light sources can be reflected by the reflector 600 toward the pattern light-transmitting layer 200 to 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 bottom to top and gradually decreases in size (i.e. from PP12 to PP10), thereby creating a dynamic visual effect that moves away from the observer and appears larger when closer and smaller when farther away.

[0069] Fifth embodiment

[0070] As shown in Figures 6A to 6C, 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. 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.

[0071] The dynamic light source 100 has a linear effective movement trajectory, meaning that each illumination position on this trajectory is an effective illumination position. Here, an "effective illumination position" refers to a position where the light emitted by the point light source at that position can illuminate the pattern reflective layer 300 to form a reflection, and this reflection can form a projected pattern on the illuminated surface 410. That is, if the light emitted by the point light source at a certain position cannot illuminate the pattern reflective layer 300 or cannot be reflected by the pattern reflective layer 300 to the illuminated surface 410 to form a projected pattern, then that position does not belong to the "effective illumination position" here. It is 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 them. In the illustrated embodiment, the dynamic light source 100 includes multiple point light sources arranged linearly and controlled to be lit sequentially, that is, the movement of the point light source positions can be achieved by software pipeline programming of these linearly arranged point light sources. In other words, in the illustrated embodiment, the movement trajectory of the dynamic light source 100 refers to the line connecting the positions of the sequentially lit point light sources (i.e., the lighting trajectory), rather than the movement trajectory of mechanical motion. According to other implementation variations, the dynamic light source 100 may also be a single point light source driven by a drive mechanism to move along its movement trajectory.

[0072] The patterned reflective layer 300 includes at least a reflective area 310 with a pattern / texture. In this first embodiment, the patterned reflective layer 300 is configured as a patterned reflector, which includes a patterned reflective area 310 and a non-reflective area 320. The patterned reflective layer 300 can be constructed in many ways, as long as it has at least a reflective area and the reflective area forms a reflective pattern with a specific design intent; the present invention does not limit this. According to other embodiments, the patterned reflective layer 300 can also be configured as one of the following forms: a patterned reflective film, a 3D freeform reflector, a micro / nano textured reflective film, a light diffraction reflective film, etc.

[0073] According to the present invention, when the dynamic light source 100 moves along its effective movement trajectory, the light emitted by the dynamic light source 100 can illuminate the reflective area 310 of the pattern reflective layer 300 to illuminate the pattern thereon, and the light from the illuminated pattern is reflected by the reflective area 310 and projected onto the illuminated surface 410 to form a dynamic visual effect of the light moving closer to or further away from the observer and appearing larger when closer and smaller when farther away. It is understood that the effective movement 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 ending point, not the time period), and the projection of the illuminated pattern onto the illuminated surface 410 monotonically increases (increases) or monotonically decreases (decreases) within one movement cycle of the dynamic light source 100.

[0074] The effective movement trajectory of the dynamic light source 100 (i.e., the direction of the motion vector of the effective illumination position) and the illuminated surface 410 form an angle greater than or equal to 0° and less than or equal to 180°, meaning the effective movement trajectory of the dynamic light source 100 can be arranged parallel to or not 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°, meaning the patterned reflective layer 300 can be arranged parallel to or not parallel to the illuminated surface 410. For example, in this fifth embodiment, the effective movement trajectory 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.

[0075] As shown in Figures 6A to 6C, when the dynamic light source 100 moves from right to left along its effective movement trajectory, that is, when multiple point light sources arranged linearly (such as the identified point light sources S13, S14, and S15) are lit sequentially from right to left, the light emitted by these point light sources can illuminate 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 in size (such as the projection images PP13, PP14, and PP15 formed by the light emitted by the identified point light sources S13, S14, and S15, respectively). This creates a dynamic visual effect that moves closer to the observer and appears larger when closer and smaller when farther away. Similarly, when the dynamic light source 100 moves from left to right along its effective movement trajectory, that is, when multiple point light sources arranged linearly are lit sequentially from left to right (i.e., from S15 to S13), the light emitted by these point light sources can illuminate 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 in size (i.e., from PP15 to PP13), thereby creating a dynamic visual effect that moves away from the observer and appears larger when closer and smaller when farther away.

[0076] Normally, when the human eye observes a moving object that is getting closer to the observer, the object's position relative to the observer is constantly changing, and the distance is gradually decreasing. Therefore, the shape of the object appears magnified as the viewing angle changes. Conversely, when the human eye observes a moving object that is getting farther away from the observer, the object's position relative to the observer is constantly changing, and the distance is gradually increasing. Therefore, when the pattern reflective layer 300 and the illuminated surface 410 are arranged as described above, and the dynamic light source 100 is arranged and moved as described above, as the position of the point light source changes, the light from the point light source, after illuminating the pattern reflective layer 300 and being reflected, projects onto the illuminated surface 410. Simultaneously, the pattern is magnified or reduced. This conforms to the natural visual pattern of the human eye observing an object as it moves from far to near or from near to far, thus creating a near-stereoscopic visual effect where the light on the illuminated surface 410 appears to move closer to or away from the observer.

[0077] The illuminated screen 400 can be configured as a flat component that is not completely transparent / semi-transparent but has a certain light transmittance. In this case, dynamic light effects can be seen on both the side of the illuminated screen 400 near the illuminated surface 410 and the side away from the illuminated surface 410. If the human eye is observing from the side of the illuminated screen 400 near the illuminated surface 410, i.e., at the first observation position 510 on the right side of the illuminated screen 400 as shown in the figure, then the dynamic light source 100 and the pattern reflective layer 300 can be an interior decoration component, and the illuminated surface 410 can belong to an interior component (such as an armrest, dashboard, or floor). (etc.), the projected pattern on the illuminated surface 410 presents an indirect rhythmic lighting effect to the observer, similar to an indirect projection ambient light. If the observer's position is on the side of the illuminated screen 400 away from the illuminated surface 410, i.e., at the second observation position 520 on the left side of the illuminated screen 400 as shown in the diagram, then the dynamic light source 100, the pattern reflective layer 300, and the illuminated screen 400 can be an interior decoration component. The side of the illuminated screen 400 away from the illuminated surface 410 is the outer surface of this decoration component, and the projected pattern on the illuminated surface 410 presents a direct rhythmic lighting effect to the observer, similar to a backlit projection ambient light. However, if the illuminated screen 400 is a non-transparent component, then the observer's position can only be on the side of the illuminated screen 400 closer to the illuminated surface 410, and the projected pattern can only serve as an indirect rhythmic lighting effect.

[0078] If multiple sets 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 from the patterned reflective layers 300 onto the illuminated surface 410 can form a dynamic visual effect composed of multiple superimposed patterns. For example, the dynamic light effects of different sets of dynamic light sources 100 correspondingly illuminating the same or different patterned reflective layers 300 and finally projected onto the illuminated surface 410 through reflection can be superimposed. Combined with different mobile software programming control of different sets of dynamic light sources 100, varied and superimposed dynamic light effects can be presented.

[0079] Furthermore, the area illuminated by the light from each moving position of a single dynamic light source 100 is limited. If the size of the illuminated surface 410 is large, only a localized area of ​​the illuminated surface 410 will be illuminated. If the product is designed to illuminate a specific area larger than that covered by a single dynamic light source 100, multiple dynamic light sources 100 can be arranged as needed to expand the illumination range of the illuminated surface 410 and meet the product's design intent.

[0080] Sixth Embodiment

[0081] As shown in Figures 7A to 7C, 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 repeated. The only difference is that in this sixth embodiment, the vehicle trim also includes a reflector 600. The reflector 600 is arranged between the patterned reflective layer 300 and the illuminated surface 410 in the light propagation path to reflect the light reflected by the patterned reflective layer 300 toward the illuminated surface 410. The reflector 600 has a flat reflective surface. The effective movement trajectory of the dynamic light source 100, the patterned reflective layer 300, and the reflective surface of the reflector 600 are arranged in pairs that are substantially parallel. Furthermore, each of the effective movement trajectory of the dynamic light source 100, the patterned reflective layer 300, and the reflective surface of the reflector 600 is arranged substantially perpendicular to the illuminated surface 410.

[0082] As shown in Figures 7A to 7C, when the dynamic light source 100 moves from right to left along its effective movement trajectory, that is, when multiple point light sources arranged linearly (such as the identified point light sources S16, S17, and S18) are lit sequentially from right to left, the light emitted by these point light sources can illuminate 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 in size (such as the projection images PP16, PP17, and PP18 formed by the light emitted by the identified point light sources S16, S17, and S18, respectively). This creates a dynamic visual effect that moves closer to the observer and appears larger when closer and smaller when farther away. Similarly, when the dynamic light source 100 moves from left to right along its effective movement trajectory, that is, when multiple point light sources arranged linearly are lit sequentially from left to right (i.e., from S18 to S16), the light emitted by these point light sources can illuminate 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 in size (i.e., from PP18 to PP16), thereby creating a dynamic visual effect that moves away from the observer and appears larger when closer and smaller when farther away.

[0083] It is understood that the reflector 600 is particularly suitable for certain applications with limited space, as it can save space through light reflection. The number, shape, arrangement angle, and position of the reflector 600 can be determined according to specific circumstances, and the present invention does not limit this. For example, multiple reflectors 600 can be provided in the vehicle trim as needed. Alternatively, the reflector 600 can be arranged between the dynamic light source 100 and the patterned reflective layer 300 in the light propagation path to reflect the light emitted by the dynamic light source 100 toward the patterned reflective layer 300.

[0084] Seventh Embodiment

[0085] As shown in Figures 8A to 8C, the overall structure of the vehicle trim according to the seventh embodiment is similar to that of the sixth embodiment. The similarities will not be described again. The only difference is that the reflector 600 has a flat reflective surface, the effective movement trajectory of the dynamic light source 100, the patterned reflective layer 300 and the illuminated surface 410 are arranged in pairs parallel to each other, and the reflective surface of the reflector 600 is arranged to be approximately parallel to each of the effective movement trajectory of the dynamic light source 100, the patterned reflective layer 300 and the illuminated surface 410 (in the figure, the effective movement trajectory of the dynamic light source 100, the patterned reflective layer 300 and the illuminated surface 410 are arranged in the vertical direction, and the reflective surface of the reflector 600 is slightly inclined relative to the vertical direction).

[0086] As shown in Figures 8A to 8C, when the dynamic light source 100 moves from bottom to top along its effective movement trajectory, that is, when multiple point light sources arranged linearly (such as the identified point light sources S19, S20, and S21) are lit sequentially from bottom to top, the light emitted by these point light sources can illuminate 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 in size (such as the projected images PP19, PP20, and PP21 formed by the light emitted by the identified point light sources S19, S20, and S21, respectively). This creates a dynamic visual effect that moves closer to the observer and appears larger when closer and smaller when farther away. Similarly, when the dynamic light source 100 moves from top to bottom along its effective movement trajectory, that is, when multiple point light sources arranged linearly are lit sequentially from top to bottom (i.e., from S21 to S19), the light emitted by these point light sources can illuminate 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 in size (i.e., from PP21 to PP19), thereby creating a dynamic visual effect that moves away from the observer and appears larger when closer and smaller when farther away.

[0087] Eighth embodiment

[0088] Figures 9A to 9D show an eighth embodiment of the present invention, which is a physical application of the vehicle trim on a car door. As shown in Figures 9A to 9D, the vehicle trim includes an upper trim panel 700, a two-tone injection-molded bracket 800 disposed below the upper trim panel 700, and a central trim panel 900 disposed below the bracket 800. One side surface of the central trim panel 900 (i.e., the right side surface shown in the figure) forms an illuminated surface 410. A dynamic light source 100 is disposed in a cavity defined by the upper trim panel 700 and the bracket 800, and includes a plurality of point light sources arranged linearly and controlled to be illuminated sequentially. That is, the position of the point light sources can be moved by software pipeline programming of these linearly arranged point light sources. The support 800 is formed by two-color injection molding of a non-opaque material 810 (e.g., ABS (acrylonitrile-butadiene-styrene plastic)) and a translucent material 820 (e.g., PC (polycarbonate)). The translucent material 820 is positioned below the dynamic light source 100, and a patterned translucent layer 200 (here, a patterned translucent film) is bonded to the bottom surface of the translucent material 820, for example, by IML (in-mold insert molding). The substrate of this translucent film is completely transparent. By screen printing opaque ink onto certain areas of the substrate, the areas covered by the screen-printed opaque ink are the non-opaque areas 220, and the areas not covered by the opaque ink form translucent areas 210 with translucent patterns. The illustrated translucent film actually contains multiple translucent patterns; this illustration only shows the dynamic change process of the projected pattern of one of the translucent patterns.

[0089] As shown in Figures 9A to 9C, when the dynamic light source 100 moves from right to left along its effective movement trajectory, that is, when multiple point light sources arranged linearly (such as the identified point light sources S22, S23, and S24) are lit sequentially 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 in size (such as the projection images PP22, PP23, and PP24 formed by the light emitted by the identified point light sources S22, S23, and S24, respectively). This creates a dynamic visual effect that moves closer to the observer and appears larger when closer and smaller when farther away. Similarly, when the dynamic light source 100 moves from left to right along its effective movement trajectory, that is, when multiple point light sources arranged linearly are lit sequentially 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 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 in size (i.e., from PP24 to PP22), thereby creating a dynamic visual effect that moves away from the observer and appears larger when closer and smaller when farther away.
