Description

Technical Field

[0001] The present invention relates to the technical field of automobile decorative parts, and in particular to a decorative surface assembly and an automobile. Background Art

[0002] Automotive interior components are the part of the car that users spend the most time in contact with. The aesthetics and comfort of automotive interior components directly impact the user experience. Traditional ambient lighting panels use a single light source, such as white, red, or yellow, which cannot display personalized patterns or shapes. Furthermore, they generally use a fully bright or fully dark LED lighting strategy.

[0003] Difficult to attract consumers.

[0004] In recent years, with the development of technology, some manufacturers have increased the display effects of the light-emitting panels in car interior parts to better meet the needs of the market. In the related art, to form a variable optical pattern, it is necessary to use a dot matrix atmosphere light. For example, Chinese utility model patent CN216976716U discloses a car interior atmosphere light emitting panel, which achieves a uniform starry sky effect and a flowing water effect by setting a pattern on an IML film and controlling the lighting order of the LED. However, the above effect is still slightly monotonous, and can only form a smart surface with a single pattern. The pattern cannot be changed and the aesthetics is poor. Especially in high-end cars, it is difficult to meet their demand for a sense of technology and luxury in car interior parts, which reduces consumers' desire to buy. Summary of the Invention

[0034] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] In view of the problem in related technologies that automobile decorative panels can only form smart surfaces with a single pattern, the pattern cannot be changed, and the aesthetics are poor.

[0036] First, as Figure 1 As shown, the present application provides a decorative surface assembly, which includes: a light-transmitting plate 1, a switching drive assembly 2 and a light source assembly 5; wherein,

[0037] A switching drive component 2 is provided on which at least one first diaphragm 3 and at least one second diaphragm 4 are provided, and different scene patterns are provided on the first diaphragm 3 and the second diaphragm 4. The switching drive component 2 is used to drive the first diaphragm 3 or the second diaphragm 4 to adhere to the inner side of the light-transmitting plate 1; a light source component 5 is provided on the inner side of the light-transmitting plate 1 and is used to emit light to the light-transmitting plate 1 to transmit the scene pattern on the first diaphragm 3 or the second diaphragm 4 adhered to the light-transmitting plate 1 to the outside of the light-transmitting plate 1.

[0038] It is understandable that in order to improve the aesthetics and richness of the decorative surface in the related art, it is generally necessary to use a dot matrix atmosphere light to achieve pattern changes, but it is not possible to switch patterns. In this application, the diaphragm assembly includes a first diaphragm 3 and a second diaphragm 4. The first diaphragm 3 or the second diaphragm 4 formulates different light transmission patterns according to the shape definition, and a switching drive component 2 is set on the inner side of the light-transmitting plate 1, and is used to switch the positions of the first diaphragm 3 and the second diaphragm 4 with two different scene patterns.

[0039] Preferably, the diaphragm assembly includes a plurality of first diaphragms 3 and second diaphragms 4 , and all the first diaphragms 3 or the second diaphragms 4 together form a scene pattern.

[0040] In combination with the first aspect, in some embodiments, the switching drive assembly 2 includes: at least one diaphragm hinge 21 and a drive unit 22; wherein,

[0041] At least one diaphragm hinge 21 is provided with the first diaphragm 3 and the second diaphragm 4, and the first diaphragm 3 and the second diaphragm 4 can rotate with the diaphragm hinge 21; a driving part 22 is connected to the diaphragm hinge 21, and the driving part 22 is used to drive the diaphragm hinge 21 to rotate, so as to drive the first diaphragm 3 and the second diaphragm 4 to fit or separate from the light-transmitting plate 1; wherein,

[0042] When one of the first film 3 or the second film 4 is attached to the light-transmitting plate 1 , the other of the first film 3 or the second film 4 is parallel to the light projection direction of the light source assembly 5 .

[0043] It is worth noting that the film hinge 21 can drive the first film 3 and the second film 4 to rotate at different angles, so that the film can be quickly moved to the transmission position on the light-transmitting plate 1. Figure 3 This is a partial schematic diagram of the switching drive assembly in the first state, at which time the first film 3 is in contact with the light-transmitting plate 1, and the pattern transmitted by the light source assembly 5 is the pattern on the first film 3. Figure 4 This is a partial schematic diagram of the driving unit 22 performing the switching action to the second state. At this time, the second film 4 is attached to the light-transmitting plate 1 , and the pattern transmitted by the light source assembly 5 is the pattern on the second film 4 .

[0044] In some preferred embodiments, the first diaphragm 3 and the second diaphragm 4 are arranged perpendicularly.

[0045] It is understandable that the first diaphragm 3 and the second diaphragm 4 are simultaneously installed on the inner side of the light-transmitting plate 1, so that when the pattern is transmitted, the first diaphragm 3 and the second diaphragm 4 block each other's light, affecting the transmission quality of the pattern. Therefore, in order to facilitate the arrangement of the light projection angle of the light source component 5, the first diaphragm 3 and the second diaphragm 4 are set vertically, and the angle between them is set to 90°. In this way, when Figure 3 As shown, when the switching drive assembly is in the first state, the first diaphragm 3 is perpendicular to the light projection direction of the light source assembly 5, and the second diaphragm 4 is parallel to the light projection direction of the light source assembly 5. The second diaphragm 4 will not block the light, ensuring the transmission quality of the first diaphragm 3. Figure 4 As shown, when the switch drive assembly is in the second state, the second diaphragm 4 is perpendicular to the light projection direction of the light source assembly 5, and the first diaphragm 3 is parallel to the light projection direction of the light source assembly 5. The first diaphragm 3 does not block the light, ensuring the image transmission quality of the second diaphragm 4.

[0046] In some specific embodiments, Figure 2 As shown, the driving part 22 includes: a first driving rod 221, a second driving rod 223 and a motor; wherein,

[0047] A first driving rod 221 has a first driving shaft 222 at one end, and the other end is connected to the lower side of the diaphragm hinge 21; a second driving rod 223 has a second driving shaft 224 at one end, and the other end is connected to the upper side of the diaphragm hinge 21; a motor is connected to the first driving shaft 222 and the second driving shaft 224, and the motor can drive the first driving rod 221 and the second driving rod 223 to move synchronously in opposite directions through the first driving shaft 222 and the second driving shaft 224 to rotate the diaphragm hinge 21.

[0048] Furthermore, the diaphragm hinge 21 extends beyond the diaphragm assembly boundary, and the section of the diaphragm hinge 21 outside the diaphragm boundary is connected to the first drive rod 221 and the second drive rod 223. The first drive rod 221 and the second drive rod 223 are arranged on the upper and lower sides of the diaphragm hinge 21. Similarly, the first drive rod 221 and the second drive rod 223 extend outside the diaphragm assembly area, avoiding the diaphragm assembly area, and are connected to the first drive shaft 222 or the second drive shaft 224.

[0049] In some specific embodiments, the switching drive assembly 2 is provided with a plurality of first diaphragms 3 and second diaphragms 4, the number of the first diaphragms 3 and the second diaphragms 4 corresponds, and two adjacent first diaphragms 3 or second diaphragms 4 are evenly spaced in the length direction of the light-transmitting plate 1.

[0050] It should be noted that different light-transmitting patterns are formulated on the first film 3 and the second film 4 according to the shape definition. A plurality of first films 3 or a plurality of second films 4 together form a pattern.

[0051] In some optional embodiments, the light source assembly 5 includes: a circuit control board 51 and a light diffusion board 53; wherein,

[0052] A circuit control board 51 is provided inside the light-transmitting board 1 , and at least one lamp bead 52 is provided on the circuit control board 51 ; and a light diffusion board 53 is provided between the circuit control board 51 and the light-transmitting board 1 .

[0053] It can be understood that the lamp bead 52 is lit by the circuit control board 51, and the light emitted by the lamp bead 52 is diffused by the light diffuser 53 and reaches the area where the first diaphragm 3 and the second diaphragm 4 are located. The light-transmitting pattern on the diaphragm transmits the optical pattern to be displayed, and the optical pattern is directly projected to the human eye through the light-transmitting plate 1 to be displayed to the occupants.

[0054] Preferably, a plurality of the lamp beads 52 are arranged at intervals on the circuit control board 51 , and the plurality of the lamp beads 52 are arranged at intervals in the length direction of the light diffusion plate 53 .

[0055] Furthermore, in order to improve the transmission quality, the light-transmitting plate 1 includes a light-transmitting surface or a light-transmitting film. Preferably, the light-transmitting plate 1 is made of PC material.

[0056] It is worth mentioning that PC material, also known as polycarbonate, is colorless and transparent, has good optical properties, and a light transmittance of up to 90%, making it suitable for applications requiring high transparency.

[0057] The working principle of the decorative surface assembly of this application includes:

[0058] Case 1: When the first film 3 is close to the light-transmitting plate 1, the second film 4 is at a 90-degree angle to the light-transmitting plate 1 to avoid blocking the image on the first film 3. The lamp beads 52 are lit by the circuit control board 51. The light emitted by the lamp beads 52 is diffused by the light diffuser 53 and reaches the area of ​​the first film 3. The light-transmitting pattern on the first film 3 transmits the first optical pattern to be displayed. The first optical pattern is directly projected through the light-transmitting plate 1 to the human eye and displayed to the occupants.

[0059] Case 2: When it is necessary to display the second set of optical pictures, a motor signal is given to the first drive shaft 222 and the second drive rod 223, and the motor drives the first drive shaft 222 and the second drive shaft 224 to rotate synchronously counterclockwise. The rotation direction can be adjusted according to the design definition. When the drive shaft rotates, it drives the first drive rod 221 and the second drive rod 223 to move, and drives the connecting rod to drive the diaphragm hinge 21 to rotate synchronously. Driven by the rotation of the diaphragm hinge 21, the first diaphragm 3 moves from close to the light-transmitting plate 1 to 90 degrees with the light-transmitting plate 1. Driven by the rotation of the diaphragm hinge 21, the second diaphragm 4 moves from 90 degrees to the light-transmitting plate to fit with the light-transmitting plate 1. The lamp bead 52 is lit through the circuit control board, and the light emitted by the lamp bead 52 is diffused through the light diffuser plate and reaches the second diaphragm 4 area. The light-transmitting pattern on the second diaphragm 4 transmits the second set of optical patterns that need to be displayed, and the second optical pattern is directly projected to the human eye through the light-transmitting plate to be displayed to the occupants.

[0092] A first driving rod 221 has a first driving shaft 222 at one end, and the other end is connected to the lower side of the diaphragm hinge 21; a second driving rod 223 has a second driving shaft 224 at one end, and the other end is connected to the upper side of the diaphragm hinge 21; a motor is connected to the first driving shaft 222 and the second driving shaft 224, and the motor can drive the first driving rod 221 and the second driving rod 223 to move synchronously in opposite directions through the first driving shaft 222 and the second driving shaft 224 to rotate the diaphragm hinge 21.

[0093] Furthermore, the diaphragm hinge 21 extends beyond the diaphragm assembly boundary, and the section of the diaphragm hinge 21 outside the diaphragm boundary is connected to the first drive rod 221 and the second drive rod 223. The first drive rod 221 and the second drive rod 223 are arranged on the upper and lower sides of the diaphragm hinge 21. Similarly, the first drive rod 221 and the second drive rod 223 extend outside the diaphragm assembly area, avoiding the diaphragm assembly area, and are connected to the first drive shaft 222 or the second drive shaft 224.

[0094] In some specific embodiments, the switching drive assembly 2 is provided with a plurality of first diaphragms 3 and second diaphragms 4, the number of the first diaphragms 3 and the second diaphragms 4 corresponds, and two adjacent first diaphragms 3 or second diaphragms 4 are evenly spaced in the length direction of the light-transmitting plate 1.

[0095] It should be noted that different light-transmitting patterns are formulated on the first film 3 and the second film 4 according to the shape definition. A plurality of first films 3 or a plurality of second films 4 together form a pattern.

[0096] In some optional embodiments, the light source assembly 5 includes: a circuit control board 51 and a light diffusion board 53; wherein,

[0097] A circuit control board 51 is provided inside the light-transmitting board 1 , and at least one lamp bead 52 is provided on the circuit control board 51 ; and a light diffusion board 53 is provided between the circuit control board 51 and the light-transmitting board 1 .

[0098] It can be understood that the lamp bead 52 is lit by the circuit control board 51, and the light emitted by the lamp bead 52 is diffused by the light diffuser 53 and reaches the area where the first diaphragm 3 and the second diaphragm 4 are located. The light-transmitting pattern on the diaphragm transmits the optical pattern to be displayed, and the optical pattern is directly projected to the human eye through the light-transmitting plate 1 to be displayed to the occupants.

[0099] Preferably, a plurality of the lamp beads 52 are arranged at intervals on the circuit control board 51 , and the plurality of the lamp beads 52 are arranged at intervals in the length direction of the light diffusion plate 53 .

[0100] Furthermore, in order to improve the transmission quality, the light-transmitting plate 1 includes a light-transmitting surface or a light-transmitting film. Preferably, the light-transmitting plate 1 is made of PC material.

[0101] It is worth mentioning that PC material, also known as polycarbonate, is colorless and transparent, has good optical properties, and a light transmittance of up to 90%, making it suitable for applications requiring high transparency.

[0102] In summary, the present application sets two switchable diaphragms inside the light-transmitting plate, and the two diaphragms are respectively provided with different scene patterns. By switching the diaphragm positions, one of the diaphragms is aligned with the light projection direction, thereby realizing the switching of different scene patterns and improving the aesthetics of the car interior. Furthermore, the present application avoids the influence of the patterns between the diaphragms by arranging the two diaphragms vertically. And by connecting the diaphragm connecting rod with multiple rotating shafts, a single drive structure drives multi-axis linkage, thereby increasing the consistency of the diaphragm flipping and solving the stability of the pattern. In the expansion scheme of the present application, the superposition of multiple diaphragms can realize the realization of multiple patterns, thereby increasing the diversified display of products.
