Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, and in particular to a trim panel with a light-transmissive pattern. The present application also relates to an optical assembly for a vehicle comprising such a trim panel. BACKGROUND

[0002] Vehicles are usually equipped with interior light boxes. An interior light box comprises a bottom plate, a top plate mounted on the bottom plate, and a light source arranged in a cavity enclosed by the bottom plate and the top plate. Generally, the top plate comprises a main body plate that is not light-transmissive and a light-transmissive pattern formed on the main body plate. When the light source is lit, light is emitted from the cavity through the light-transmissive pattern to make the interior light box display the pattern.

[0003] Generally, when manufacturing the top plate, a plurality of spaced-apart hollow units are formed on the main body plate in advance, and then transparent material is separately injected into the hollow units to form the light-transmissive pattern. However, in the case of a relatively fine light-transmissive pattern, the size of the hollow units is small and the distance between adjacent hollow units is also small, which makes it difficult to separately arrange gates for injecting transparent material at the hollow units, thereby making it difficult to manufacture the interior light box. SUMMARY

[0004] To solve the above technical problems, the first aspect of the present application provides a trim panel with a light-transmissive pattern. The trim panel comprises a main body plate that is not light-transmissive, having an inner surface and an outer surface opposite to the inner surface; a plurality of spaced-apart hollow units are formed on the main body plate; and a light-transmissive pattern comprising a plurality of pattern units formed by injecting light-transmissive material into the corresponding hollow units; wherein an injection flow channel is formed on the inner surface of the main body plate; the injection flow channel is in communication with at least one of the plurality of hollow units.

[0005] In one embodiment, the injection flow channel is filled with light-transmissive material, and at least part of the light injected into each pattern unit is adapted to spread in the light-transmissive material in the injection flow channel connected to the pattern unit to form a light-stray distance in the injection flow channel; the length of the injection flow channel between any two of the plurality of hollow units is greater than the light-stray distance.

[0006] In one embodiment, the injection flow channel comprises a first flow channel having an extension portion spaced apart from the light-transmissive pattern, and a second flow channel extending from the extension portion of the first flow channel and in communication with at least one of the plurality of hollow units.

[0007] In one embodiment, the number of second flow channels is a plurality, and the connection points of adjacent two second flow channels to the first flow channel are spaced apart from each other.

[0008] In one embodiment, the plurality of cutout units include a first cutout unit connected to the first flow channel via a second flow channel; and a second cutout unit spaced apart from the second flow channel and the first flow channel; the injection flow channel further includes a connecting flow channel connecting the first cutout unit and the second cutout unit, such that the second cutout unit is connected to the second flow channel via the connecting flow channel and the first cutout unit.

[0009] In one embodiment, the connecting channel is configured in a curved form.

[0010] In one embodiment, the connection between the second flow channel and the first flow channel is constructed with an arc-shaped chamfer.

[0011] In one embodiment, the first flow channel is annular and surrounds multiple hollow units.

[0012] In one embodiment, the first flow channel is straight, and multiple hollow units are located on the same side or both sides of the first flow channel.

[0013] In one embodiment, at least a portion of at least one patterned unit protrudes from the inner surface of the body plate.

[0014] A second aspect of this application provides an optical assembly for a vehicle. The optical assembly includes a base plate; a trim panel with a light-transmitting pattern as described above, the trim panel being connected to the base plate and together defining a cavity; and a plurality of light sources disposed within the cavity; each light source being configured to correspond to a corresponding pattern unit such that light emitted by each light source is emitted through the corresponding pattern unit.

[0015] The beneficial effects of this application are as follows: According to the technical solution of this application, an injection molding channel communicating with at least one hollow unit is provided on the inner surface of the main body plate. When manufacturing the trim panel, gates can be provided at the hollow unit and / or in the injection molding channel respectively, so that these gates do not interfere with each other, which reduces the manufacturing difficulty of the trim panel and the optical components for vehicles including the trim panel.

[0051] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] In this application, the term "outside" refers to a direction generally away from the light source; the term "inside" refers to a direction generally towards the light source, which is the opposite of the direction indicated by "outside".

[0053] Figure 1 A vehicle 1 according to one embodiment of this application is schematically shown. Figure 1 As shown, vehicle 1 includes multiple interior trim pieces, such as dashboard 10, headliner 11, and door panels 12. An optical assembly 2 for the vehicle (hereinafter referred to as optical assembly 2) may be provided on any of these interior trim pieces to enable the interior trim piece to display specific optical effects as needed.

[0054] Reference Figure 2 and Figure 3 The optical component 2 includes a base plate 21, multiple light sources 22, and a decorative panel 3 with a light-transmitting pattern (hereinafter referred to as the decorative panel 3).

[0055] The decorative panel 3 includes an opaque main panel 31 and a translucent pattern 32 on the main panel 31. The translucent pattern 32 includes a plurality of translucent pattern units 321. For example, these pattern units 321 are spaced apart from each other.

[0056] In some embodiments, the light source 22 can be an LED chip. Of course, the light source can also be any other suitable light-emitting device, and there are no limitations on this.

[0057] The base plate 21 is constructed as an open receiving groove. The decorative panel 3 is connected to the base plate 21 and together defines the cavity 201. Multiple light sources 22 are located within the cavity 201 and are respectively arranged corresponding to the corresponding pattern units 321 on the decorative panel 3. When these light sources 22 are lit, the light emitted by each light source 22 passes through the corresponding pattern unit 321 and exits outside the cavity 201, so that the optical component 2 (or the decorative panel 3) displays a pattern.

[0058] It should be understood that in some embodiments, the trim panel can also be applied separately to interior components of the vehicle, as long as the interior component can provide light suitable for illuminating the patterned unit, which will not be elaborated here.

[0059] It should also be understood that, depending on the actual situation, the translucent patterns on the decorative panels can be constructed to display beacons, images, numbers, letters, symbols, etc., without any restrictions.

[0060] The first embodiment of the decorative panel will now be described.

[0061] Reference Figure 4A and Figure 5 In the first embodiment, the main body plate 31 of the decorative panel 3 has an inner surface 311 facing the light source 22 and an outer surface 312 opposite to the inner surface 311 (i.e., the outer surface 312 faces away from the light source 22). A plurality of spaced-apart cutout units 313 are constructed on the main body plate 31. By injection molding a light-transmitting material into each cutout unit 313, these cutout units 313 are formed into light-transmitting pattern units 321. These pattern units 321 constitute a light-transmitting pattern 32 on the main body plate 31.

[0062] like Figure 5 As shown, each pattern unit 321 is generally a straight line segment, and these pattern units 321 are combined to form three Arabic numerals "8" side by side (i.e., the light-transmitting pattern 32 includes three Arabic numerals "8" side by side). In this way, the optical component 2 is adapted to display numbers.

[0063] In one embodiment, the body panel 31 and the translucent pattern 32 (or pattern unit 321) are manufactured by two-color injection molding. The first shot of the two-color injection molding uses an opaque material (e.g., opaque ABS or PC-ABS, etc.) to form an opaque body panel with a perforated pattern. The second shot of the two-color injection molding injects a translucent material (e.g., transparent PC or acrylic, etc.) into the perforated pattern to form a translucent pattern on the body panel. The two-color injection molding process is well known to those skilled in the art and will not be described in detail here. Of course, other materials and / or other processes, such as insert molding, can also be used to manufacture the body panel and the translucent pattern, depending on the specific circumstances.

[0064] Reference Figure 4A , Figure 6A and Figure 6B An injection molding channel 33 is formed on the inner surface 311 of the main body plate 31. The injection molding channel 33 communicates with these hollow units 313. In one embodiment, at least part or all of the injection molding channel 33 may be recessed within the main body plate 31; at least part or all of the injection molding channel 33 may also protrude beyond the inner surface of the main body plate 33, as may be determined according to the actual situation.

[0065] When manufacturing the decorative panel 3 of this application, multiple gates 333 can be provided at the hollowed-out unit 313 and / or on the injection runner 33, so that the spacing between these gates 333 is large and they do not interfere with each other. In this way, injection molding material can be conveniently injected into each hollowed-out unit 313 through these gates 333 and the injection runner 33, thereby completing the manufacturing of the decorative panel 3. It should be understood that in the decorative panel 3, both the injection runner 33 and the hollowed-out unit 313 are filled with a light-transmitting material.

[0066] Furthermore, according to the decorative panel 3 of this application, along the thickness direction D of the main body panel 31, each pattern unit 321 is completely surrounded by the opaque main body panel 31 (e.g., Figure 6A and Figure 6B (As shown). Thus, after the light source 22 is lit, the light emitted by the light source 22 can only be emitted from the corresponding pattern unit 321, and cannot be emitted from adjacent or other pattern units (i.e., the pattern unit corresponding to a certain light source cannot be lit by other light sources). This avoids light crosstalk on the decorative panel 3 and helps to clearly display the translucent pattern 32 on the decorative panel 3. In this application, light crosstalk refers to the phenomenon where at least a portion of the light emitted by one or more light sources is emitted from the pattern unit corresponding to one or more other non-light-emitting light sources, resulting in at least a portion of that pattern unit being lit.

[0067] In some embodiments not shown, the light-transmitting pattern protrudes from the inner surface of the main body panel. This protruding structure helps improve the assembly accuracy of the trim panel and the base plate, avoiding light leakage caused by assembly errors.

[0068] likeFigure 4A As shown, the injection molding runner 33 includes a first runner 331 and multiple second runners 332.

[0069] The first flow channel 331 is an elliptical ring surrounding the hollowed-out units 313, and is also spaced apart from these hollowed-out units 313 (i.e., the first flow channel is not directly connected to each hollowed-out unit). Of course, depending on the actual situation, the first flow channel can also be constructed as a ring, which is not limited here. In some embodiments not shown, the first flow channel can also be constructed as a non-closed shape, such as a straight segment or a curved segment. In this case, one or both ends of the first flow channel can be connected to one or more hollowed-out units, and the portion between the two ends of the first flow channel forms an extension spaced apart from the light-transmitting pattern.

[0070] Each second runner 332 extends from the first runner 331 into the area defined by the first runner 331 and communicates with at least one of these cutout units 313. Thus, the first runner 331 can have a longer length, thereby providing more space for the gate 333, which further facilitates the manufacture of the decorative panel 3. The specific lengths of the first runner 331 and the second runner 332 can be determined according to actual conditions and are not limited here.

[0071] For example Figure 4A As shown, the connection points of the two adjacent second runners 332 and the first runner 331 are spaced apart from each other. In this case, gates 333 can be provided at the connection points of the second runners 332 and the first runner 331 (i.e., the number of gates 333 is equal to the number of second runners 332), and adjacent gates 333 do not interfere with each other. Compared with setting gates at other locations on the first runner, setting the gates at the connection points helps to reduce the amount of injection molding material remaining in the injection runners 33 during the injection molding process, thereby improving the effective utilization rate of injection molding material and reducing the manufacturing cost of the decorative panel 3. Of course, depending on the actual situation, gates can also be set at positions away from the connection points on the first runner and / or the second runner, and / or at certain hollowed-out patterns, as long as adjacent gates do not interfere with each other.

[0072] In some cases, during the injection molding process, the injection materials in different second flow channels 332 can flow to each other through the first flow channel 331 to replenish each other, so as to ensure that all the hollow units 313 are filled.

[0073] In some cases, the number of gates is less than the number of second runners. This allows for a greater distance between adjacent gates, further preventing interference between them. During injection molding, the injection material flows through the first runner into each of the second runners and eventually fills all the cutout units.

[0074] In other cases, where the number of cutout units is large and / or complex, multiple first runners can be provided. These first runners are spaced apart from each other, and one or more second runners extend from each first runner. A gate is provided on each first runner (and / or the corresponding second runner), so that the distance between adjacent gates can be greater, further avoiding interference between adjacent gates.

[0075] The connection between each second runner 332 and the first runner 331 is constructed with an arc-shaped chamfer (not shown in the figure). During the injection molding process, the chamfer helps to reduce the flow resistance of the injection molding material and avoid the formation of weld lines or cold runner marks at the connection point between the second runner 332 and the first runner 331, thereby improving the sensory quality of the trim panel 3.

[0076] In one embodiment, the first flow channel 331 is recessed within the body plate 31, and the depth of the first flow channel 331 is between 30% and 60% of the thickness of the body plate 31. The same applies to the second flow channel 332. For example, if the thickness of the body plate 31 is between 2 mm and 3 mm, the depth of the first flow channel 331 (or the second flow channel 332) is between 1 mm and 1.2 mm. This results in lower flow resistance of the injection molding material within the injection channel 33. The widths of the first flow channel 331 and the second flow channel 332 can be determined according to actual conditions; for example, both can be approximately 2 mm wide, which also helps reduce the flow resistance of the injection molding material within the injection channel 33. Of course, the depth and width of the first flow channel 331 and the second flow channel 332 can also be other values ​​depending on the actual conditions.

[0077] For example Figure 4A As shown, these cutout units 313 include a plurality of first cutout units 313a and a plurality of second cutout units 313b. Each first cutout unit 313a is connected to a second flow channel 332 (i.e., each first cutout unit 313a is connected to a first flow channel 331 via a second flow channel 332), and the second cutout units 313b are spaced apart from the first flow channel 331 and these second flow channels 332. The injection molding runner 33 also includes a connecting flow channel 334 (e.g., connecting at least one first cutout unit 313a and at least one second cutout unit 313b) connecting at least one first cutout unit 313a and at least one second cutout unit 313b. Figure 6B(As shown), each second hollow unit 313b is thus connected to the corresponding second flow channel 332 via a corresponding connecting channel 334 and the corresponding first hollow unit 313a, and further connected to the first flow channel 331. For example, a straight connecting channel 334 connects two oppositely arranged first hollow units 313a and second hollow units 313b. Also, for example, in the case where two first hollow units 313a and two second hollow units 313b form a rectangle, a generally cross-shaped connecting channel 334 is constructed within the rectangle. The four ends of this cross-shaped connecting channel 334 are respectively connected to the two first hollow units 313a and the two second hollow units 313b. Thus, during injection molding, the injection material in the first hollow unit 313a can flow into the corresponding second hollow unit 313b via the connecting channel 334 to fill these second hollow units 313b with injection material.

[0078] It should be noted that in the cross-shaped connecting channels, the bends of the connecting channels are also constructed with rounded chamfers to reduce the flow resistance of the injection molding material.

[0079] It should also be noted that, such as Figure 4B As shown, the first flow channel is filled with a light-transmitting material 331a, the second flow channel is filled with a light-transmitting material 332a, and the connecting flow channel is filled with a light-transmitting material 334a. Taking the light-transmitting material 334a in the connecting flow channel as an example, after the light source is lit, at least a portion of the light incident on each pattern unit can diffuse within the light-transmitting material 334a in the connecting flow channel connected to that pattern unit, thus forming a light-crossing distance within the connecting flow channel. In other words, as the light propagates within the light-transmitting material 334a in the connecting flow channel, the brightness of the light gradually decreases. The length along the corresponding connecting flow channel between the pattern unit and the position where the brightness of the light decreases to a predetermined value is the light-crossing distance. It should be noted that the "predetermined value of light brightness" mentioned above can be determined according to actual conditions, and will not be elaborated here. In one embodiment, the light-crossing distance is related to the brightness of the light source, the flow channel parameters, the light-guiding performance of the light-transmitting material, etc.

[0080] The length of the connecting channel between any two hollow units (or pattern units) is greater than the light-transmitting distance. Thus, when using the decorative panel 3, light illuminating one pattern unit will not propagate through the transparent injection molding material in the connecting channel 334 to adjacent pattern units (i.e., light leakage between these two pattern units is prevented through the connecting channel), thereby improving the display quality of the decorative panel 3. The same applies to the first and second channels, which will not be elaborated further here.

[0081] In one embodiment, the connecting channel 334 is configured in a curved form (the light-transmitting material 334a within the connecting channel is also correspondingly curved) to prevent light leakage between the two pattern units connected by the curved connecting channel. For example, in the case where two first cutout units 313a and two second cutout units 313b form a rectangle, the cross-shaped connecting channel can prevent light leakage between the cutout units that are the two adjacent sides of the rectangle.

[0082] The second embodiment of the decorative panel will now be described.

[0083] The decorative panel in the second embodiment is largely the same as that in the first embodiment; the differences between the two are mainly described below. Figure 7A As shown, three spaced-apart arc-shaped cutout patterns 313 are constructed on the main body plate 31, and the three cutout patterns 313 are generally concentric. After injecting a light-transmitting material into each cutout unit 313, a pattern unit 321 is formed. For example, these pattern units 321 are combined to form a light-transmitting pattern 32 that can be used to indicate WiFi signals (such as...). Figure 8 (As shown).

[0084] For example Figure 7A As shown, the injection molding runner 33 includes a first runner 331 and three second runners 332. The first runner 331 is generally annular and surrounds the hollowed-out units 313, and is also spaced apart from the hollowed-out units 313. Each second runner 332 connects one hollowed-out unit 313 to the first runner 331.

[0085] The connection points between these second runners 332 and the first runner 331 are spaced apart from each other. A gate 333 is provided at each connection point, and adjacent gates 333 do not interfere with each other.

[0086] It should be understood that, although Figure 7A The diagram shows two second flow channels directly opposite each other radially to the first flow channel 331, with the remaining second flow channel at a 90-degree angle to both of them. However, three second flow channels can also be arranged in other ways depending on the actual situation. For example, the three second flow channels can be evenly distributed circumferentially along the first flow channel, and the three gates can also be evenly distributed circumferentially along the first flow channel accordingly.

[0087] like Figure 7B As shown, the first flow channel is filled with light-transmitting material 331a, and the second flow channel is filled with light-transmitting material 332a. Similar to the first embodiment of the decorative panel, in... Figure 7B In this case, the length of the flow channel between any two pattern units is greater than the light-scattering distance formed within that flow channel. For example... Figure 8 As shown, each of the three pattern units 321 is completely surrounded by an opaque main body plate 31. Therefore, no light leakage occurs between the three pattern units 321.

[0088] The third embodiment of the decorative panel will now be described.

[0089] The decorative panel in the third embodiment is largely the same as that in the first embodiment; the differences between the two are mainly described below. Figure 9A As shown, three spaced-apart circular cutout patterns 313 are constructed on the main body plate 31, and the three cutout patterns 313 are generally arranged in a straight line. After injecting a light-transmitting material into each cutout unit 313, a pattern unit 321 is formed. For example, these pattern units 321 are combined to form a light-transmitting pattern 32 that can be used to indicate a certain intensity level signal (such as...). Figure 10 (As shown).

[0090] For example Figure 9A As shown, the injection molding runner 33 includes a first runner 331 and three second runners 332. The first runner 331 is straight, and the three cutout patterns 313 are located on the same side of the first runner 331. The first runner 331 is also spaced apart from these cutout units 313. The length of the first runner 331 can be equal to or greater than the length of the line segment on which the three cutout patterns 313 are located. Each second runner 332 connects one cutout unit 313 to the first runner 331.

[0091] A gate 333 is provided on the first runner 331. During the injection molding process, injection molding material is injected into the three cutout units 313 through this gate 333. Of course, multiple gates can also be provided on the first runner, or some gates can be set at the cutout pattern and / or on the second runner, as long as adjacent gates do not interfere with each other.

[0092] It should be understood that, depending on the actual situation, the three perforated patterns can also be distributed on both sides of the straight first flow channel, and the three second flow channels are correspondingly distributed on both sides of the first flow channel. For example, one perforated pattern is on one side of the first flow channel, and the other two perforated patterns are on the other side of the first flow channel; correspondingly, one second flow channel is on one side of the first flow channel and connected to the one perforated pattern, and the other two second flow channels are on the other side of the first flow channel and connected to the other two perforated patterns respectively.

[0093] like Figure 9B As shown, both the first and second flow channels are filled with a translucent material. Similar to the first embodiment of the decorative panel, in... Figure 9B In this case, the length of the flow channel between any two pattern units is greater than the light-scattering distance formed within that flow channel. For example... Figure 10 As shown, each of the three pattern units 321 is completely surrounded by an opaque main body plate 31. Therefore, no light leakage occurs between the three pattern units 321.
