[0035] In view of the problem in the related art that the automobile decorative panel can only form an intelligent surface with a single pattern, the pattern cannot be changed, and the aesthetics is 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 with at least one first diaphragm 3 and at least one second diaphragm 4, 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 fit with 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 that fits with the light-transmitting plate 1 to the outer side of the light-transmitting plate 1.

[0038] It is understandable that in order to improve the aesthetics of the decorative surface and enhance the richness in the related art. Generally, it is necessary to use a dot matrix atmosphere light to achieve pattern changes, but the pattern cannot be switched. In the present application, the diaphragm assembly includes a first diaphragm 3 and a second diaphragm 4. The first diaphragm 3 or the second diaphragm 4 defines different light-transmitting patterns according to the shape, 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 the 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 FIG. 1 is a partial schematic diagram of the switching drive assembly in the first state, in which the first film 3 is attached to 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 It is a partial schematic diagram of the driving unit 22 switching 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 vertically.

[0045] It is understandable that the first film 3 and the second film 4 are installed at the same time on the inner side of the light-transmitting plate 1, so that when transmitting the pattern, the first film 3 and the second film 4 shield each other from 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 film 3 and the second film 4 are arranged vertically, and the angle between them is set to 90°. In this way, when Figure 3 As shown, when the switch driving 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 driving 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 will 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, one end of which is provided with a first driving shaft 222, and the other end is connected to the lower side of the diaphragm hinge 21; a second driving rod 223, one end of which is provided with a second driving shaft 224, and the other end is connected to the upper side of the diaphragm hinge 21; a motor, which 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, so as to rotate the diaphragm hinge 21.

[0048] Furthermore, the diaphragm hinge 21 extends to the outside of 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, avoid 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 the first diaphragms 3 and the 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 disposed inside the light-transmitting board 1 , and at least one lamp bead 52 is disposed on the circuit control board 51 ; and a light diffusion board 53 is disposed 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 plate 53 to reach 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 that require 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 with the light-transmitting plate 1 to avoid shielding the picture on the first film 3. The lamp beads 52 are lit through the circuit control board 51, and the light emitted by the lamp beads 52 is diffused through the light diffusion plate 53 to reach the area of ​​the first film 3. The light-transmitting pattern on the first film 3 transmits the first optical pattern to be displayed, and the first optical pattern is directly projected to the human eye through the light-transmitting plate 1 to be 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 counterclockwise synchronously. 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 diffusion plate to reach 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, one end of which is provided with a first driving shaft 222, and the other end is connected to the lower side of the diaphragm hinge 21; a second driving rod 223, one end of which is provided with a second driving shaft 224, and the other end is connected to the upper side of the diaphragm hinge 21; a motor, which 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, so as to rotate the diaphragm hinge 21.

[0093] Furthermore, the diaphragm hinge 21 extends to the outside of 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, avoid 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 the first diaphragms 3 and the 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 disposed inside the light-transmitting board 1 , and at least one lamp bead 52 is disposed on the circuit control board 51 ; and a light diffusion board 53 is disposed 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 plate 53 to reach 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 that require 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 automotive interior. Furthermore, the present application arranges the two diaphragms vertically to avoid the influence of the patterns between the diaphragms. And by connecting the diaphragm connecting rod with multiple rotating shafts, a single drive structure drives multi-axis linkage, increases the consistency of diaphragm flipping, and solves the stability of the pattern. In the expansion scheme of the present application, multiple patterns can be realized by superimposing multiple diaphragms, thereby increasing the diversified display of products.
