[0030] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0031] Reference below Figure 1-Figure 5 The ambient light assembly 100 according to the embodiment of the present application is described. The ambient light assembly 100 can be applied to a vehicle to decorate the vehicle and create an atmosphere, thereby improving the driving experience of the driver and passengers.

[0032] The ambient light assembly 100 according to the embodiment of the present application includes: a light guide bar 2 and a diffusion plate 3 .

[0033] The light guide bar 2 can be connected to the light emitting unit 1 and used for guiding light, and the light emitting unit 1 can emit a light signal, which can be guided to the side of the diffuser plate 3 through the light guide bar 2. The diffuser plate 3 is connected to the light guide bar 2, and a light shielding pattern 4 is provided on the wall surface of the diffuser plate 3 opposite to the light guide bar 2. The light shielding pattern 4 can shield the light transmitted from the light guide bar 2 to the diffuser plate 3 to ensure the uniformity of light output from the diffuser plate 3.

[0034] It can be understood that the shading pattern 4 is formed on the diffuser plate 3, which does not occupy additional space while ensuring the shading effect. It can improve the compactness of the layout between the light guide bar 2 and the diffuser plate 3, reduce the occupied space of the atmosphere light assembly 100, and thus reduce the difficulty of installing and arranging the atmosphere light assembly 100.

[0035] It should be noted that, currently, the decorative effect of the vehicle is enhanced by setting up ambient lights, but the ambient lights have uneven light output and are overly bright in some areas, which results in light spots at the ambient lights, affecting the user experience. In the related art, the light spots are reduced by increasing the thickness of the light-transmitting plate locally, but this will result in a clear boundary between the light in the thick wall area, affecting the light presentation effect of the flavor, etc.; or by increasing the distance between the light-emitting component and the light-transmitting plate, but this will result in a larger space occupied by the ambient lights, increasing the difficulty of assembling the ambient lights.

[0036] In the present application, a shading pattern 4 is provided on the diffuser plate 3, and the shading pattern 4 can block the light emitted from the light guide bar 2 to the diffuser plate 3 to improve the uniformity of light output from the diffuser plate 3, and the shading pattern 4 is formed on the diffuser plate 3 and does not occupy space, which can ensure the compactness of the arrangement between the light guide bar 2 and the diffuser plate 3, thereby reducing the size of the atmosphere lamp assembly 100 and reducing the difficulty of arranging the atmosphere lamp assembly 100.

[0037] like Figure 1 and Figure 5 As shown, in a further embodiment of the present application, the light guide strip 2 includes a main segment 21 and a branch segment 22, the main segment 21 is connected to the diffuser 3, one end of the branch segment 22 is connected to the light-emitting unit 1, and the other end of the branch segment 22 is connected to the main segment 21, and is used to guide the optical signal to the main segment 21.

[0038] Among them, one end of the branch segment 22 is connected to the light-emitting unit 1, and the light emitted by the light-emitting unit 1 is guided by the branch segment 22 to one side of the main segment 21, and further guided to the diffuser plate 3 through the main segment 21, so that the layout of the light guide strip 2 and the diffuser plate 3 is reasonable, which facilitates the arrangement of the light-emitting unit 1 in a suitable installation position.

[0039] It is understandable that the light guide bar 2 is used to guide the light signal emitted by the light emitting unit 1 to one side of the diffuser 3. In the present application, the light emitting unit 1 is arranged at one end of the branch segment 22, and there is no need to directly connect the light emitting unit 1 to the main segment 21, so that the light emitting unit 1 can be arranged in a position suitable for installation and avoiding other components (such as the main segment 21 and the diffuser 3). Figure 1That is to say, in the present application, there is no need to arrange the light-emitting unit 1 at both ends of the main segment 21 to prevent the arrangement position of the light-emitting unit 1 from being limited. The shape of the branch segment 22 can be designed according to the arrangement requirements of the light-emitting unit 1 so that the incident end of the branch segment 22 (i.e., the end connected to the light-emitting unit 1) can be arranged in a suitable area, such as: the middle position or other positions, which are not specifically limited here.

[0040] In some embodiments of the present application, the light guide strip 2 can be fixedly connected to the light guide strip 2 by means of a snap-on connection. The snap-on connection method is simple and has high reliability, which can reduce the difficulty of assembling the atmosphere light assembly 100.

[0041] The diffusion plate 3 is provided with a snap-fit ​​structure (such as a snap buckle, a snap slot, etc.), and the light guide bar 2 (such as the main body section 21 ) can be snap-fitted with the snap-fit ​​structure.

[0042] like Figure 1 and Figure 5 As shown, in some embodiments of the present application, there are two branch segments 22, the two branch segments 22 are respectively connected to the two light-emitting units 1, and the connection between the two branch segments 22 and the main segment 21 is arranged adjacent to each other. In this case, the optical signal can be transmitted to the main segment 21 through the two branch segments 22, and the optical signal transmitted to the main segment 21 through the branch segments 22 can be further transmitted to the diffuser 3 through the main segment 21.

[0043] Here, “adjacent arrangement” means that the connection between one branch segment 22 and the main segment 21 is adjacent to the connection between another branch segment 22 and the main segment 21. That is, the light conducted by the two branch segments 22 may meet at the connection between the main segment 21 and the two branch segments 22.

[0044] It should be noted that each branch section 22 is provided with a corresponding light emitting unit 1, and the light signals emitted by the two light emitting units 1 are respectively guided to one side of the main section 21 through the two branch sections 22, and are further guided to the diffuser 3 from the main section after intersecting at the main section 21. Figure 1 , the connection area between the two branch segments 22 and the main segment 21 is located in the middle of the main segment 21 in the length direction, so that light can enter the middle of the main segment 21, and further guide the light signal to the diffuser 3 through the main segment 21. The "middle" refers to the area near the middle in the length direction, and is not limited to the middle position.

[0045] Therefore, the light guide strip 2 in the present application adopts the method of light entering in the middle of the main section 21 to reduce the distance of light mixing at both ends, increase the light-emitting area of ​​the atmosphere light, increase the light-guiding length of the main section 21, and enhance the light-emitting effect of the atmosphere light assembly 100.

[0046] like Figure 4As shown, in some embodiments of the present application, the shading pattern 4 includes: a first shading area 41 and a second shading area 42. The connecting area 201 of the main segment 21 and the two branch segments 22 is arranged opposite to the first shading area 41, and the second shading area 42 is arranged outside the first shading area 41, and the second shading area 42 is arranged adjacent to the first shading area 41. Figure 4 , “Connection area 201” is a connection surface.

[0047] Among them, the shading pattern 4 has multiple shading areas (such as: a first shading area 41 and a second shading area 42), each of which corresponds to multiple light-emitting areas of the main segment 21, so that the light of the corresponding light-emitting area can be specifically blocked.

[0048] It is understandable that the light guide bar 2 in the present application uses the middle light entry method to let in light, so that the brightness in the middle area of ​​the light guide bar 2 (i.e., the intersection of the main segment 21 and the two branch segments 22) is high, which makes it easy to produce light spots at the diffuser 3, so a light-shielding area with better light-shielding ability is needed to block the light to reduce the bright spots. The light-shielding abilities of the multiple light-shielding areas of the light-shielding pattern 4 in the present application can be different, so as to ensure the uniformity of light output at the diffuser 3 while reducing the bright spots, thereby improving the light output effect of the atmosphere lamp assembly 100.

[0049] The above-mentioned “high brightness” refers to the brightness of the middle region compared to other positions (such as the two ends of the main body segment 21 in the length direction, etc.).

[0050] In the present application, the light-transmitting area per unit area of ​​the first light-shielding area 41 is S1, and the light-transmitting area per unit area of ​​the second light-shielding area 42 is S2, and the relationship is satisfied: S1<S2. Therefore, the area per unit area of ​​the first light-shielding area 41 that can be used for the light beam to pass through and be emitted to the diffuser plate 3 is smaller than the area per unit area of ​​the second light-shielding area 42 that can be used for the light beam to pass through and be emitted to the diffuser plate 3, that is, the light-shielding effect of the first light-shielding area 41 is better than the light-shielding effect of the second light-shielding area 42.

[0051] It can be understood that the first shading area 41 is arranged corresponding to the area with strong light output from the light guide strip 2 (i.e., the intersection of the main segment 21 and the two branch segments 22). The first shading area 41 can reduce the light entering the diffuser plate 3, thereby weakening the brightness of the diffuser plate 3 in the first shading area 41, thereby ensuring the uniformity of the light output from the diffuser plate 3.

[0052] The surface of the diffuser plate 3 opposite to the light guide bar 2 is used for light to be disposed on, and the surface of the diffuser plate 3 away from the light guide bar 2 (the side opposite to the passenger compartment) is used for presenting light.

[0053] Reference Figure 5The first shading area 41 and the second shading area 42 are both grid-shaped, and the grid density of the first shading area 41 is greater than that of the second shading area 42. The first shading area 41 has a better light shielding effect on the light guide strip 2, and can prevent the light on the other side surface of the diffuser plate 3 from having bright spots or obvious boundaries.

[0054] At the same time, since the first shading area 41 and the second shading area 42 are arranged adjacent to each other, the shading pattern 4 can ensure the shading effect of the diffuser 3, thereby preventing the diffuser 3 from being partially incident with excessive light.

[0055] It should be noted that the pattern shape and color of the first shading area 41 and the second shading area 42 are not specifically limited here, and can be designed according to the actual application of the atmosphere light assembly 100. For example, the shading pattern 4 can be constructed in a grid shape, a line shape, a honeycomb shape, etc., and the color of the shading pattern 4 can be black, blue, red, etc.

[0056] like Figure 3 As shown, in some embodiments of the present application, the main segment 21 has a light emitting surface, which is opposite to and spaced from the light shading pattern 4 , thereby reserving a gap between the light guide bar 2 and the diffuser plate 3 to reduce the brightness of light incident on the diffuser plate 3 .

[0057] like Figure 3 As shown, in a further embodiment of the present application, the vertical distance between the light emitting surface and the surface of one side of the diffuser plate 3 provided with the light shielding pattern 4 is L, and the relationship is satisfied: 0.5mm≤L≤2mm. When the distance L between the light guide bar 2 and the diffuser plate 3 satisfies the above parameter range, it can prevent the light guide bar 2 and the diffuser plate 3 from being too close to cause bright spots to appear on the diffuser plate 3, so that the diffuser plate 3 presents uniform light.

[0058] Preferably, L is 1 mm, so that the layout between the light guide bar 2 and the diffuser plate 3 is compact, which can reduce the size of the atmosphere light assembly 100, save the space occupied by the atmosphere light assembly 100, and reduce the installation space requirement of the atmosphere light assembly 100 in the vertical direction.

[0059] It is understandable that, currently, the uniform lighting effect of the atmosphere lamp is achieved by increasing the distance between the light guide structure and the diffuser. Usually, the distance between the light emitting surface of the light guide structure and the incident surface of the diffuser is in the range of 5mm-10mm, which results in the large size of the atmosphere lamp and inconvenience in assembly.

[0060] In the present application, the incident surface of the diffuser plate 3 (i.e., the surface on one side of the diffuser plate 3 opposite to the light emitting surface of the light guide bar 2) is provided with a shading pattern 4. The shading pattern 4 can reduce the light incident on the diffuser plate 3, reduce the brightness of the light presented by the diffuser plate 3, and improve the uniformity of the light presented by the ambient light. Compared with the existing technical solutions, the distance between the light guide bar 2 and the diffuser plate 3 can be reduced, saving the space occupied by the ambient light assembly 100.

[0061] In some embodiments of the present application, the atmosphere light assembly 100 also includes a shading member 5, which is connected to the light-emitting unit 1, and the shading member 5 is mounted on the branch segment 22 to shield the area on the branch segment 22 that does not need to be illuminated by the shading member 5, thereby avoiding the occurrence of bright spots due to illuminating the places where bright light is not needed, thereby ensuring the lighting presentation effect of the atmosphere light assembly 100.

[0062] like Figure 3 As shown, in some embodiments of the present application, the diffuser plate 3 includes a light-transmitting plate segment, which is arranged opposite to the light-emitting surface of the light guide bar 2 and is used for light to be transmitted, and the thickness of each position of the light-transmitting plate segment is consistent.

[0063] In some embodiments of the present application, the shading pattern 4 is a pad printing pattern. The pad printing pattern is simple to form and easy to process. The pad printing pattern does not take up space and can also block and disperse bright light, thereby maintaining the consistency of the thickness of the light-transmitting plate segment.

[0064] In the present application, the diffuser plate 3 is constructed as a low-transmittance translucent plastic part. The diffuser plate 3 can reduce the light output after the light guide strip 2 guides the light, so that the diffuser plate 3 presents a better uniform light and avoids the diffuser plate 3 presenting uneven light.

[0065] like Figure 1 As shown, in some embodiments of the present application, the ambient light assembly 100 further includes a wiring harness 6, one end of which is connected to the light-emitting unit 1, and the other end of the wiring harness 6 is provided with a connector 7, and the connector 7 is used to connect signals.

[0066] The light emitting unit 1 is the light source in the ambient light assembly 100. When the ambient light assembly 100 is applied to a vehicle, the wiring harness 6 is used to connect the power supply to the light emitting unit 1, and the connector 7 is used to receive signals and selectively energize.

[0067] According to the vehicle of the embodiment of the present application, the vehicle includes the above-mentioned ambient light assembly 100, the components in the ambient light assembly 100 are compactly arranged, the required installation space is small, and the ambient light assembly 100 presents good lighting uniformity. At the same time, the light guide bar 2 adopts the middle light input, which can increase the light guiding distance of the light guide bar 2 and enhance the lighting presentation effect of the ambient light assembly 100.

[0068] In the present application, the light-emitting unit 1 can be connected to the light guide strip 2 (such as the branch segment 22) by snapping, and Bingjie guides the light to the diffuser 3 through the light guide strip 2. The shielding member is covered on the branch segment 22 and part of the light-emitting unit 1 to prevent light leakage and the appearance of bright spots.

[0069] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0070] In the description of this application, "first feature" or "second feature" may include one or more of the features.

[0071] In the description of the present application, “plurality” means two or more.

[0072] In the description of the present application, a first feature being “on” or “under” a second feature may include that the first and second features are directly in contact with each other, or may include that the first and second features are not in direct contact with each other but are in contact with each other via another feature therebetween.

[0073] In the description of the present application, “above”, “over” and “above” a first feature to a second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is horizontally higher than the second feature.
