Description

Technical Field

[0001] The present invention relates to the technical field of automobile interior decoration, and in particular to a manufacturing method and a control method of an ultra-long integrated luminous interior decoration component assembly based on a multi-layer composite structure. Background Art

[0002] As people's requirements for car interiors gradually increase, more and more models are adding a large number of ambient lights to enhance the visual effect and sense of luxury of the car interior. As an important component of luminous interior components, traditional ultra-long luminous light guide plates currently used in large buses, minibuses, large MPVs and other models generally have the following technical defects:

[0003] 1. Overall mass and thickness are relatively high: Traditional long-length illuminated interiors require improved structural stability and brightness uniformity for ultra-long light guide plates (PMMA sheets are commonly used for light guide plates, with a thickness of 3-6mm. Currently, more than 99% of solutions in the automotive market do not exceed 2.5m in length). Most use direct-lit LED light sources, with a total thickness of ≥25mm, while a few use side-lit light sources. However, this requires a high degree of mechanical strength to resist deformation, making it difficult to meet lightweight design requirements.

[0004] 2. Segmented backlight structure: For TVs over 2.5 meters, most use an integrated backlight + split frame, or a split backlight + split frame. When the light guide plate is lit, obvious bright spots appear at the splicing point, affecting the complete visual experience.

[0005] 3. Heavy materials and complex manufacturing: The main frame is mostly made of U-shaped stainless steel or aluminum alloy, which has high processing costs, low efficiency, and poor consistency after assembly. The process is also complex, and the light guide plate needs to be fixed to the frame by punching holes and screwing (the holes in the light guide plate affect internal optical transmission and scattering, resulting in localized brightness unevenness) or bonding with double-sided tape (the car body has relatively low stability under random vibration conditions). To achieve higher optical contrast, the surface decorative layer is mostly made of PVC or PU artificial leather with printed patterns, which affects the user's visual and tactile experience.

[0006] 4. Limitations in communication control: Traditional solutions typically use CAN and LIN protocols to communicate with the vehicle body control unit (central control screen) for lighting effect changes, node mode, and other functions. Simultaneously using Bluetooth (in conjunction with a mobile app) for remote control is often difficult. The mismatch between protocols and logical instructions (system architecture priorities) limits the flexibility and convenience of communication control.

[0007] 5. The lighting effects are relatively simple and the immersive experience is low: Traditional solutions have few lighting presets, basically common modes such as flowing water, breathing, and RGB color temperature changes. They lack perception and interaction with the current environment and lack creative uniqueness.

[0008] 6. Disadvantages in power consumption and heat dissipation performance: Most traditional ultra-long luminous interior parts use direct-down light source solutions (with a large number of LED lamp beads and high power consumption); a few use side-entry light source solutions, which are limited by the material properties of the decorative layer (although the number of lamp beads has been reduced, it is still limited by the transmittance and uniformity of the decorative layer material). This results in low overall brightness of the luminous components and low contrast in the pattern area, and still requires relatively high power consumption (brightness) to make up for the shortfall. When the LED light strip (because it is bonded to the main frame with double-sided tape, and the light guide plate and the frame are also coordinated over a large area) is turned on, heat will be quickly transferred to the entire product surface, affecting the user experience.

[0009] 7. Disadvantages of inspection, maintenance, and disassembly and repair: Since the traditional LED light strip is fixed to the frame by bonding (to save space and ensure that energy is not lost too much, the lamp beads are close to the light guide plate), it is difficult to quickly troubleshoot the circuit failure of the light strip (the decorative layer needs to be completely removed to visually see the light strip) and replace it efficiently, which requires a lot of work;

[0010] 8. Environmental issues: The traditional solution is to produce luminous patterns through multi-layer printing on the surface of the decorative layer (translucent PVC leather, PU leather, etc. as the base material) and the back base fabric. The VOC indicators of the base material itself and the ink need to be strictly controlled.

[0011] 9. The fixed mounting seat (hole position) is restricted by the vehicle body environment and lacks the freedom of adjustment. Summary of the Invention

[0036] The beneficial effects of the present invention are as follows:

[0037] 1. The ultra-long integrated luminous interior component assembly manufactured by the present invention achieves the advantages of ultra-long integrated backlight of more than 5.5m, light transmittance of the pattern area ≥90%, brightness uniformity ≥85%, peak brightness ≥5000nit, brightness adjustment range: 200~4000nit, color temperature adjustment range: 2700K~6500K, low power consumption of 12W (≤2.2W per linear meter) for 5.5m projection, and compatibility with CAN, LIN, Bluetooth and other communication protocols for system-side control.

[0038] 2. The light guide plate of the present invention adopts a lightweight design cut from PMMA sheet materials. Through laser engraving of the light guide network structure, its thickness is only 6mm and its length is ≥5.5m. It can greatly reduce the weight of the main frame of the traditional solution. In addition, the light guide plate can also adopt optical-grade LCP (liquid crystal polymer) or PSU (polysulfone) with better performance, with the transmittance increased to 98% and the thickness can be reduced to 3mm (50% lower than PMMA).

[0039] 2. The vehicle body hanger of the present invention can be freely adjusted in the guide groove, and the LED light strip can be quickly pulled out from the side, which is convenient for inspection and replacement, and convenient for later installation, debugging and modification. In addition, the light strip seat and the vehicle body hanger are clearance-fitted, which has a certain "blocking" effect on the heat generation of the LED light strip. Compared with the existing technology of directly bonding the light strip to the frame, it can solve the problem of assembly heating and improve the user experience.

[0040] 3. The integrated luminous interior parts assembly of the present invention adopts an integrated light guide plate + integrated upper and lower frames + integrated light strip holder + side-entry LED light source integrated structure, which is highly ornamental from a visual perspective, ensuring the continuity and integrity of the luminous pattern, and compared with the split-type solution in the prior art that produces a bright spot effect at the splicing point; the integrated solution ensures higher consistency and effectively solves the problems of the split-type solution at the splicing point, such as welding marks (unevenness), flatness, straightness, and poor assembly tolerance.

[0041] 4. The decorative layer of the present invention adopts optical-grade highly transparent (98% transmittance) silicone leather to replace the semi-transparent (transmittance of about 60-70%) PVC, PU leather and other materials of traditional solutions, which results in less light energy loss, better overall brightness and contrast of the pattern area, and easier and more precise control of color temperature (silicone leather has the properties of resistance to light aging and yellowing), which significantly reduces the power consumption required compared with traditional solutions. In addition, the pattern of the decorative layer is made by laser engraving on the surface to produce a texture pattern, and on the back side, a base cloth (or fabric) is used to engrave a pattern, so that the backlight can be transmitted from the hollow area of ​​the laser engraving to the surface; if a one-way transparent film is added, it can be made into a hidden or direct-display pattern to enhance the "immersive" visual experience.

[0042] 5. The present invention can simultaneously perform Bluetooth (mobile phone APP) control based on CAN and LIN bus control. The priority principle is based on the last initiated instruction, which perfectly solves the conflicts and incompatibility problems and improves the flexibility and convenience of communication control.

[0043] 6. The pattern of the present invention can be hidden or directly displayed to enhance the grade and texture of interior products, and the lighting effects are added with "environmental perception" and "rhythmic interaction" effects on the basis of traditional solutions (flowing water, breathing, RGB, etc.).
