Description of the drawings: in the following description, the direction from the flexible skin layer to the vehicle frame is from "outer" to "inner".
In a first aspect, referring to fig. 1, the present invention provides a light-transmitting flexible board for a vehicle, including a flexible skin layer 100, a flexible pattern layer 200, a flexible light guide layer 300, a light source 400 and a flexible light source fixing layer 500, where the flexible pattern layer 200 has light-transmitting patterns, the light source 400 is located inside the flexible light guide layer 300 and includes a plurality of sub light sources 410 that are distributed and disposed, the plurality of sub light sources 410 are fixed on an inner surface of the flexible light guide layer in a manner of protruding from the inner surface of the flexible light guide layer, the flexible light source fixing layer 500 includes a plurality of fixing holes corresponding to positions of the plurality of sub light sources 410, and each sub light source 410 is respectively embedded in the corresponding fixing hole; the flexible light source fixing layer is used for being connected with the vehicle framework; the flexible pattern layer 200 is printed on the inner surface of the flexible skin layer 100; the flexible skin layer 100 is a colored artificial leather, the flexible skin layer 100 presents the appearance of the artificial leather, and after at least one sub-light source 410 of the light sources 400 is turned on, the flexible skin layer 100 can emit the pattern of the flexible pattern layer 200.
The light-transmitting flexible board for the vehicle provided by the invention is fixed on the vehicle frame 600 after the flexible surface layer 100, the flexible pattern layer 200, the flexible light guide layer 300 and the light source 400 are matched with the flexible light source fixing layer 500 (as can be understood by those skilled in the art, the pattern layer and the light guide layer of the invention do not necessarily contact with each other, and other functional structural layers such as a flexible foaming layer and the like can be arranged between the two layers), because the surface layer 100, the pattern layer 200, the light guide layer 300 and the light source fixing layer 500 are all flexible structures, and the light source 400 is in the form of a plurality of sub light sources 410 which are distributed and arranged, and are embedded into a plurality of fixing holes corresponding to the positions of the sub light sources 410 in the light source fixing layer 500, the light sources are used as sub light sources of the vehicle interior light source, for example, miniature light sources such as small-sized LED bulbs can be selected, so that the flexible light sources are embedded into the light source fixing layer 500 after being distributed and arranged on the inner side of the light guide layer 300, the light source fixing layer 500 can not significantly affect the flexible special light source fixing layer 300 and the flexible decorative part of the light guide layer 600, and the flexible frame can be connected with any transparent decorative board, so long as a transparent adhesive, and a vehicle frame to be suitable for being connected with a transparent decorative board for a vehicle, such as a transparent car to be used. According to the invention, the vehicle interior trim matched with the appearance of the parts to be decorated is not required to be manufactured respectively aiming at the different parts to be decorated of different vehicle types, so that the labor production efficiency in the field of vehicle interior trim is greatly improved, and the production cost such as mold opening is also obviously saved.
Meanwhile, the light guide layer 300 (for example, a light guide film capable of converting light emitted by a point light source into a surface light source) outside the sub light sources 410 can further sufficiently scatter light rays emitted by the sub light sources which are distributed, the light rays are backlight relative to the flexible pattern layer 200, the backlight can irradiate light-transmitting patterns arranged on the flexible pattern layer 200, and the patterns are uniform because the obtained backlight is not provided with areas which have relatively dark display effects or even are not irradiated by the backlight, so that passengers can see the patterns which are uniform in light emission and uniform in display effect, and beautiful visual perception is obtained.
Furthermore, the manner of setting the light source 400 as the plurality of sub-light sources 410 according to the present invention provides a precondition for the individual control manner of whether each sub-light source emits light, the emission color, the emission brightness level, and the like, and can obtain an extremely beautiful, uniform, and vivid interior decoration effect for a vehicle. Further, since the sub-light sources 410 of the present invention protrude from the inner surface of the flexible light guide layer 300 (for example, the sub-light sources are adhered to the inner surface of the light guide layer and protrude from the inner surface by the adhering arrangement), and the flexible light source fixing layer 500 is embedded, after the vehicle light-transmitting flexible board is integrally bent to match the portion to be decorated, the distances between the sub-light sources 410 and the light guide layer 300 will not change after the sub-light sources are bent along with the light source fixing layer 500, the light-emitting decoration effect will not change significantly, and the present invention has strong decoration practicability.
The flexible skin layer 100 may be a colored artificial leather layer, the outer surface of the light-transmitting flexible board for a vehicle may have an artificial leather texture when the light source 400 is not turned on, and the pattern on the flexible pattern layer 200 can be transmitted through the skin layer 100 after at least one sub-light source 410 of the light source 400 is turned on. In order to ensure the light transmission of the flexible skin layer 100, the pattern on the surface of the flexible skin layer is clearer as much as possible, the thickness of the flexible skin layer 100 can be reduced as much as possible while the strength and toughness of the flexible skin layer are ensured, and the light transmission of the opaque toner on the skin layer can be ensured by enhancing the dispersibility of the toner in the skin layer raw material, reducing the particle size of the toner (for example, setting the particle size of the toner to be in the nanometer range, such as 0.3-20 nm) and other means so as to reduce the light transmission of the skin layer as low as possible. The sub-light sources 410 are selected in light emitting intensity and are matched with the light transmission capacity of the flexible skin layer 100, so that when the light sources 400 are turned off, the flexible skin layer 100 presents the appearance of the artificial leather, and after at least one sub-light source 410 in the light sources 400 is turned on, the flexible skin layer 100 can transmit the pattern of the flexible pattern layer 200.
In combination with the top view of the flexible pattern layer 200 shown on the right side of fig. 1, the flexible pattern layer 200 may be formed by printing opaque ink with a certain thickness (the opaque effect is achieved by selecting the color of the ink and the appropriate printing thickness) on the corresponding portion of the inner surface of the flexible skin layer 100, and the transparent pattern is formed by not printing any ink; the flexible pattern layer 200 may also be formed by using a piece of light-blocking paper disposed on the inner side of the flexible skin layer 100, and cutting a hollow pattern on the light-blocking paper to form a light-transmitting pattern region on the flexible pattern layer; furthermore, the flexible pattern layer 200 may also be a film disposed inside the flexible skin layer 100, the film itself is transparent, opaque ink is printed on the non-pattern area of the film to a certain thickness, and the area without black ink is the pattern area. The method for forming the flexible pattern layer through printing is most convenient and feasible, and the production efficiency of the light-transmitting flexible board for the vehicle can be obviously improved.
Preferably, the plurality of sub-light sources 410 are separately controlled by respective control elements.
Preferably, the manner of the separate control is as follows: and respectively controlling the control element of each sub-light source through a PLC (programmable logic controller) so as to realize that the plurality of sub-light sources are separately controlled.
It can be understood that each sub-light source 410 in the light-transmitting flexible board for vehicle needs to be connected with an external power supply, an external control element, etc., and is not a stand-alone component, otherwise, the normal light-emitting decoration effect cannot be realized. Each sub-light source and an external power source, an external control element, etc. may be connected through a connection line to realize power supply, control signal transmission, etc., and these connection lines may be arranged in a manner of slotting on the light source fixing layer, or directly sandwiched between the flexible light source fixing layer 500 and the flexible light guide layer 300.
Each of the sub-light sources 410 has its own control element, so that whether each sub-light source emits light, the emission color, the emission brightness level, and the like can be individually controlled. It is understood that these control elements are integrated in a control system of the vehicle, which can be operated by the passenger, for example, there is a PLC controller in the control system, and there are various keys arranged on an operation interface outside the operation system, the passenger can select which sub-light source/sub-light sources emit light and which color/brightness light is emitted by operating the corresponding keys, of course, the keys may also indicate different light-emitting effects instead of which sub-light sources emit light, the passenger can select different light-emitting effects by operating the corresponding keys, and the PLC controller receives the corresponding light-emitting effect command to control which sub-light source/sub-light sources emit light and control the light-emitting colors and light-emitting brightness thereof, etc.
Preferably, the arrangement positions and the arrangement outlines of the sub-light sources 410 in the light source 400 correspond to the pattern on the flexible pattern layer 200.
In the case that the pattern on the flexible pattern layer 200 is determined, the arrangement position and the arranged outline of the plurality of sub light sources 410 in the light source 400 may be made to correspond to the pattern on the flexible pattern layer 200, and the sub light sources 410 are not disposed at the positions corresponding to the non-pattern regions. Therefore, the arrangement of ineffective light sources can be reduced, and energy can be saved.
Of course, it is also possible to uniformly distribute the plurality of sub-light sources 410, so that the sub-light sources can be adapted to different patterns of pattern layers, and the flexible pattern layer 200 can be replaced without changing other structures of the vehicular light-transmitting flexible board.
Preferably, the non-pattern area on the flexible pattern layer 200 is a black light blocking area.
In order to improve the contrast of pattern display, the non-pattern area on the flexible pattern layer 200 may be set as a black light-blocking area, so that the display boundary of the pattern on the flexible pattern layer 200 is clearer and the display effect of the pattern is clearer.
Preferably, a flexible foam layer 700 and a flexible base fabric layer 800 are also provided between the flexible pattern layer 200 and the flexible light guide layer 300.
In order to enhance the hand feeling of the light-transmitting flexible board for vehicle of the present invention, a flexible foam layer 700 may be further disposed between the flexible pattern layer 200 and the flexible light guide layer 300, and it can be understood by those skilled in the art that the thickness of the flexible foam layer 700 should be as thin as possible and the foaming rate should be as low as possible on the premise of satisfying certain softness and strength requirements, so as to reduce the covering effect on the light emission of the light source as much as possible. Preferably, the thickness of the flexible foaming layer can be 0.1mm-1mm, and the foaming rate is 1.2-1.7.
The flexible base fabric layer 800 mainly serves as a mechanical support for the light-transmitting flexible board for the vehicle as a whole. The flexible foam layer 700 and the flexible base fabric layer 800 may be fixed to each other by hot pressing or adhesion, and a glue layer (not shown) is disposed between the flexible foam layer 700 and the flexible base fabric layer 800 when the two are combined by adhesion. Further, one of the fixing methods of the flexible base fabric layer 700 and the flexible light guide layer 800 may be adhesion, that is, a glue layer (not shown) is also disposed between the flexible base fabric layer 700 and the flexible light guide layer 800.
When the effect of the softness demand of this automobile-used printing opacity flexonics board is satisfied more than, compare in all setting up flexible foaming layer 700 and flexible base cloth layer 800 in the technical scheme in the outside of flexible pattern layer 200, all set up flexible foaming layer 700 and flexible base cloth layer 800 at flexible pattern layer 200 inboardly, can make flexible pattern layer 200 be closer to flexible epidermal layer 100, like this, the process light behind flexible pattern layer 200 is when going out through flexible epidermal layer 100, and the scattering of light is obvious littleer to the influence of formation of image, and the pattern of observing from the external world is just more clear.
Preferably, a surface treatment agent layer (not shown) is further provided on the outer surface of the flexible skin layer 100.
The surface treatment agent layer can play a role in scraping resistance, wear resistance, chemical reagent resistance, heat resistance, aging resistance and the like, and further can be a coating with luster, so that the surface of the light-transmitting flexible plate for the vehicle can be provided with the luster.
In a second aspect, referring to fig. 2, the invention further provides a vehicle skeleton assembly, which includes a vehicle skeleton 600, a light source 400 and a light-transmitting flexible component, where the light-transmitting flexible component includes a flexible skin layer 100, a flexible pattern layer 200 and a flexible light guide layer 300, the flexible pattern layer 200 has light-transmitting patterns, the light source 400 is located inside the flexible light guide layer 300 and includes a plurality of sub light sources 410 arranged in a distributed manner, the plurality of sub light sources 410 protrude out of the inner surface of the flexible light guide layer 300, the vehicle skeleton 600 includes a plurality of fixing holes corresponding to the positions of the plurality of sub light sources, and each sub light source 410 is respectively embedded into the corresponding fixing hole;
the flexible pattern layer 200 is printed on the inner surface of the flexible skin layer 100;
the flexible skin layer 100 is a colored artificial leather, when the light source is turned off, the flexible skin layer 100 presents the appearance of the artificial leather, and after at least one sub-light source 410 of the light source 400 is turned on, the flexible skin layer 100 can show the pattern of the flexible pattern layer 200.
The vehicle skeleton assembly provided by the invention can form a light-transmitting flexible component by adopting the flexible skin layer 100, the flexible pattern layer 200 and the flexible light guide layer 300 (as can be understood by a person skilled in the art, the pattern layer and the light guide layer are not necessarily mutually contacted, and other functional structural layers such as a flexible foaming layer can be arranged between the two layers), and then the light-transmitting flexible component is fixed on the vehicle skeleton 600, because the skin layer 100, the pattern layer 200 and the light guide layer 300 are all flexible structures, and miniature light sources such as small LED bulbs are used as sub light sources, the sub light sources 410 are respectively arranged on the inner surface of the light guide layer 300 and do not obviously influence the flexible characteristics of the light guide layer 300, therefore, the vehicle skeleton assembly provided by the invention has the flexible characteristics of the flexible skin layer 100, the flexible pattern layer 200 and the flexible layer 300 with the plurality of sub light sources 410 protruding from the inner surface, and can be matched with the vehicle skeleton 600 in any shape, no matter the specific shape of the vehicle skeleton 600, the flexible skin layer 100, the flexible pattern layer 200 and the flexible light guide layer 300 with the plurality of sub light sources 410 are arranged on the inner surface, and can be correspondingly bent into different shapes, namely, and the vehicle skeleton assembly can be correspondingly bent.
Meanwhile, the sub-light sources 410 are distributed on the inner surface of the light guide layer 300 to achieve a certain degree of dispersion effect on the light emitting effect of the light sources, the light guide layer 300 (for example, a light guide film capable of converting light emitted by a point light source into a surface light source) on the outer side of the sub-light sources 410 can further sufficiently scatter light emitted by the distributed sub-light sources 410, the light is backlight relative to the flexible pattern layer 200, the backlight can irradiate light-transmitting patterns arranged on the flexible pattern layer 200, and the obtained backlight is uniform, so that no areas with relatively dark display effect or even no backlight irradiation are formed in the patterns, so that passengers can see the patterns with uniform light emission and uniform display effect, and the visual experience is very beautiful.
Furthermore, the manner of setting the light sources as the plurality of sub-light sources 410 according to the present invention provides a precondition for an individual control manner of whether each sub-light source 410 emits light or not, if so, the emission color and the emission brightness level, etc., and thus, an extremely beautiful, uniform and vivid interior decoration effect for a vehicle can be obtained. Further, since the sub-light sources 410 of the present invention protrude from the inner surface of the light guide layer 300 (for example, the sub-light sources are adhered to the inner surface of the light guide layer and protrude from the inner surface by adhesion), and are embedded in the vehicle frame, after the flexible light guide layer 300 is bent along with the shape of the vehicle frame 600, the distances between the sub-light sources 410 and the light guide layer 300 will not change, the light emitting decoration effect will not change significantly, and the present invention has strong decoration practicability.
The flexible skin layer 100 may be a colored artificial leather layer, and when the light source 400 is turned off, the outer surface of the vehicle frame assembly has the texture of artificial leather, and when the light source is turned on, the patterns on the flexible pattern layer 200 can be transmitted through the skin layer 100. In order to ensure the light transmission of the flexible skin layer 100, the pattern on the surface of the flexible skin layer can be clearer as much as possible, the thickness of the flexible skin layer can be reduced as much as possible while the strength and toughness of the flexible skin layer are ensured, and the light transmission of the opaque toner on the skin layer can be ensured by enhancing the dispersibility of the toner in the skin layer raw material, reducing the particle size of the toner (for example, setting the particle size of the toner to be in the nanometer range, such as 0.3-20 nm) and the like. The sub-light sources 410 are selected in light emitting intensity and are matched with the light transmission capacity of the flexible skin layer 100, so that when the light sources 400 are turned off, the flexible skin layer 100 presents the appearance of the artificial leather, and after at least one sub-light source 410 in the light sources 400 is turned on, the flexible skin layer 100 can transmit the pattern of the flexible pattern layer 200.
With reference to the schematic top view of the flexible pattern layer 200 shown on the right side of fig. 2, the flexible pattern layer 200 may be formed by printing opaque ink with a certain thickness (the opaque effect is achieved by selecting the color of the ink and the appropriate printing thickness) on the corresponding portion of the inner surface of the flexible skin layer 100, and the transparent pattern is formed by not printing any ink; the flexible pattern layer 200 may also be formed by using a piece of light-blocking paper disposed on the inner side of the flexible skin layer 100, and cutting a hollow pattern on the light-blocking paper to form a light-transmitting pattern region on the flexible pattern layer 200; furthermore, the flexible pattern layer 200 may be a film disposed on the inner side of the flexible skin layer 100, the film itself is transparent, opaque ink is printed on the non-pattern area of the film to a certain thickness, and the area where the black ink is not printed is the pattern area. The method for forming the flexible pattern layer through printing is most convenient and feasible, and the production efficiency of the automobile framework component can be obviously improved.
In a third aspect, referring to fig. 3, the present invention further provides a method for manufacturing the light-transmitting flexible board for the vehicle, which includes the following steps:
s100, printing a flexible pattern layer 200 on the inner surface of the flexible skin layer 100;
s200, fixing the flexible skin layer 100, on the inner surface of which the flexible pattern layer 200 is printed, on the outer side of the flexible light guide layer 300;
s300, bonding the sub light sources 410 at corresponding positions on the inner surface of the flexible light guide layer 300 to obtain a first semi-finished product, and coating an adhesive layer on the parts, which are not bonded with the sub light sources, on the inner surface of the flexible light guide layer;
s400, forming a plurality of fixing holes in the flexible light source fixing layer 500;
and S500, covering the semi-finished product obtained in the step S300 on a flexible light source fixing layer 500, enabling the plurality of sub-light sources 410 to be respectively embedded into the corresponding fixing holes, and enabling the part, which is not bonded with the sub-light sources, of the inner surface of the flexible light guide layer to bond the semi-finished product and the flexible light source fixing layer 500 into a whole through the adhesive layer.
As will be understood by those skilled in the art, the phrase "fixing the flexible skin layer having the flexible pattern layer printed on the inner surface to the outside of the flexible light guide layer" in step S200 does not necessarily mean that the flexible skin layer having the flexible pattern layer printed on the inner surface is fixed to the outer surface of the flexible light guide layer, but may be fixed to the outside of the flexible light guide layer as long as the flexible skin layer having the flexible pattern layer printed on the inner surface is at the installation position (for example, a flexible foam layer may be provided between the flexible skin layer having the flexible pattern layer printed on the inner surface and the outer surface of the flexible light guide layer, and the flexible skin layer, the flexible foam layer, and the flexible light guide layer having the flexible pattern layer printed on the inner surface are then fixed together by hot pressing, adhering, or the like).
In addition, the above-mentioned steps S100 to S500 do not represent the order of actual production steps, for example, since S400 "forming a plurality of fixing holes on the light source fixing layer" is not performed depending on the steps S100 to S300, at least step S400 may be performed in synchronization with at least one of the steps S100/S200/S300, or the step S400 may be performed over a time span spanning at least two of the steps S100, S200, and S300.

s300, bonding the sub light sources 410 at corresponding positions on the inner surface of the flexible light guide layer 300 to obtain a second semi-finished product, and coating an adhesive layer on the parts, which are not bonded with the sub light sources, on the inner surface of the flexible light guide layer;
s400, forming a plurality of fixing holes in the vehicle frame 600;
and S500, covering the second semi-finished product obtained in the step S300 on the vehicle frame 600, enabling the plurality of sub-light sources 410 to be respectively embedded into the corresponding fixing holes, and enabling the part, which is not bonded with the sub-light sources, of the inner surface of the flexible light guide layer 300 to bond the semi-finished product and the vehicle frame 600 into a whole through the adhesive layer.
As will be understood by those skilled in the art, the phrase "fixing the flexible skin layer with the flexible pattern layer printed on the inner surface to the outside of the flexible light guide layer" in step S200 does not necessarily mean that the flexible skin layer with the flexible pattern layer printed on the inner surface is fixed to the outer surface of the flexible light guide layer, but may be fixed to the outside of the flexible light guide layer as long as the flexible skin layer with the flexible pattern layer printed on the inner surface is at the installation position (for example, a flexible foam layer may be provided between the flexible skin layer with the flexible pattern layer printed on the inner surface and the outer surface of the flexible light guide layer, and then the flexible skin layer, the flexible foam layer and the flexible light guide layer with the flexible pattern layer printed on the inner surface are fixed together by hot pressing or pasting, etc.).
In addition, the above-mentioned S100-S500 does not represent the order of actual production steps, for example, since S400 "opening a plurality of fixing holes on the frame" is not performed depending on the steps S100-S300, at least step S400 may be performed simultaneously with at least one of steps S100/S200/S300, or the time span of performing step S400 spans at least two of steps S100, S200, and S300.
