[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 2 As shown, this embodiment provides an ambient lighting assembly for an electric vehicle's dashboard. The assembly includes a dashboard housing and an illumination mechanism. The illumination mechanism is housed within the dashboard housing and includes a light-blocking plate 1 and a light-emitting unit 2. The dashboard housing has a light-transmitting area 3, and the light-blocking plate 1 covers the light-emitting unit 2 so that the light emitted by the unit 2 can be emitted through the light-transmitting area 3. With this configuration, the light emitted by the unit 2 can only be guided to the designated light-transmitting area 3 through the light-blocking plate 1, thereby achieving directional light transmission, preventing light scattering and crosstalk, and ensuring that the light propagates along a predetermined path. This not only ensures uniform brightness in the illuminated area but also further optimizes the light transmission path, achieving precise control of light efficiency, effectively reducing energy loss, and achieving a dual improvement in energy saving and light efficiency.

[0031] Specifically, this embodiment provides the following exemplary technical solution: the light-emitting unit 2 includes an LED light source 21 and a PCB board 22. A light-blocking plate 1 is fixedly installed on the PCB board 22 via clips or positioning posts, and the light-blocking plate 1 covers the LED light source 21. The LED light source 21 is disposed on the PCB board 22, and the light emitted by the LED light source 21 can be emitted through the light-transmitting area 3. It should be noted that the light-blocking plate 1 completely covers the LED light source 21 to avoid lateral light scattering.

[0032] Optionally, the instrument housing includes an upper instrument cover 4 and a lower instrument cover 5. The upper instrument cover 4 is mounted on the lower instrument cover 5. The ambient lighting assembly of the instrument panel in the electric vehicle also includes a light filter film 6, which is disposed between the upper instrument cover 4 and the light shield 1. With this configuration, the light emitted by the LED light source 21 is directionally guided by the light shield 1, and after being homogenized in the light-transmitting area 3 of the lower instrument cover 5, it shines through the upper instrument cover 4, achieving a high-contrast display without crosstalk and significantly improving the optical effect.

[0033] It should be noted that during actual assembly, the filter film 6 needs to be flatly attached to the surface of the light-blocking plate 1 to ensure that there are no bubbles or wrinkles, and the filter film 6 needs to be aligned with the edge of the light-blocking plate 1 to avoid light leakage.

[0034] Furthermore, to enhance the stability of the bond between the light-shielding plate 1 and the instrument cover 4, one side of the filter film 6 is attached to the light-shielding plate 1, and the other side of the filter film 6 is bonded to the instrument cover 4. It should be noted that the filter film 6 is an optical thin film that selectively transmits or reflects light of a specific wavelength, and its main function is to control the spectral characteristics of light according to requirements.

[0035] In this embodiment, the filter film 6 needs to be flatly attached to the surface of the light shield 1. In order to ensure that the light shield 1 and the instrument cover 4 are tightly attached, an optical grade adhesive (such as transparent UV adhesive) is evenly applied to the surface of the filter film 6. Then, the instrument cover 4 is aligned with the position of the light shield 1 and pressed together, and appropriate pressure is applied to fill the gap with adhesive. After curing, a tight optical interface is formed.

[0036] It should be noted that the gap between the light shield 1 and the instrument cover 4 should not exceed 0.1mm to prevent adhesive overflow or poor adhesion. The adhesive needs to be cured for 30 minutes at 25℃ and 50% humidity, or accelerated by UV lamp (wavelength 365nm, intensity ≥50mW / cm²). 2 After assembly, a light effect test (e.g., brightness uniformity ≥90%) and a vibration test (amplitude 2mm, frequency 10-500Hz, continuous for 1 hour without loosening) are required.

[0037] Optionally, the instrument panel ambient lighting assembly of the electric vehicle also includes a connector 7, which sequentially passes through the upper instrument cover 4, the light filter film 6, the light shielding plate 1, and the PCB board 22, and connects to the lower instrument cover 5. Further, the connector 7 is a bolt. This arrangement, secured by bolts, enhances the stability of the connection, forming a complete and robust instrument housing structure, while simultaneously achieving light transmission and instrument protection functions. It should be noted that the bolt holes must be pre-designed with an anti-loosening structure.

[0038] Optionally, the surface of the instrument cover 4 is treated with black masterbatch for light blocking, with the light blocking rate controlled at approximately 95%. It should be noted that black masterbatch is a functional plastic colorant based on high-concentration black pigments (such as carbon black or black dyes) dispersed in a carrier resin (such as PP, PE, or ABS). One of its core functions is light blocking, that is, reducing the light transmittance of the material by absorbing or scattering light. With this design, the instrument cover 4 utilizes a black masterbatch light blocking process, precisely controlling the light transmittance through specially formulated black masterbatch particles, effectively suppressing direct light while allowing multiple diffuse reflections within the instrument, significantly improving light uniformity and ensuring uniform, soft, and glare-free illumination in the display area.

[0039] Optionally, the lower casing 5 of the instrument panel is made of white PC diffusing agent material, and black paint is sprayed on the designated spraying area 8 to block the light source and form a light-transmitting area 3. In addition to the black-painted area, the lower casing 5 of the instrument panel adopts a 75% light-blocking rate design. This design allows light to diffuse moderately to the side, creating a uniform and soft backlight effect, effectively avoiding glare problems caused by direct sunlight, and ensuring visual comfort and clear display. It should be noted that white PC (polycarbonate) diffusing agent is a functional additive used to improve light uniformity and enhance haze. Its core function is to scatter light, making the light source softer and reducing glare, while maintaining the high light transmittance and impact resistance of PC.

[0040] In the optical performance optimization design, the lower instrument panel 5 ensures soft light dispersion by precisely controlling the uniformity of light diffusion, and together with the high-efficiency light-blocking technology of the upper instrument panel 4, effectively suppresses direct glare. The two work together to achieve the ideal effect of delicate, soft, and non-glaring ambient lighting, effectively enhancing the driver's visual experience.

[0041] Optionally, in order to achieve efficient side reflection processing of the light emitted by the LED light source 21, the light shield 1 is made of white PPO light-blocking material, and the light shield 1 has a light blocking rate of 100%. It should be noted that white PPO (polyphenylene oxyde) light-blocking material is a high-performance engineering plastic that achieves light shielding function by modifying PPO resin. It is suitable for applications that require high heat resistance, dimensional stability, and simultaneous blocking of visible light / ultraviolet rays.

[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
