Description

Technical Field

[0001] This utility model relates to the field of automobile door handles, and more specifically, to a structure for a light-shielding ambient light inside an automobile door handle recess. Background Technology

[0002] As the demand for personalized configurations in the automotive consumer market increases, starry sky effect ambient lighting has gradually become one of the signature features of mid-to-high-end models. Starry sky effect ambient lighting simulates the starry sky through projection technology, enhancing the romantic atmosphere inside the car. It is a decorative lighting fixture that simulates the starry sky effect inside the car through fiber optic technology, projection, or LED processes. It is commonly found in original equipment configurations or aftermarket modifications of high-end models, creating a romantic and dreamy driving atmosphere.

[0003] However, current starry sky effect ambient lighting is generally used for car interior roof decorations and is relatively large, making it unsuitable for use on car door handles. Current car door handle lighting solutions have technical limitations due to their limited range of lighting effects, typically using one or more single white LED beads that light up directly or gradually fade in and out. These solutions only illuminate the handle area and cannot provide vehicle information display or emotional guidance. Furthermore, starry sky effect ambient lighting places extremely high demands on the quality, effect, and spatial requirements of the product's surface finishing process.

[0004] For example, the aforementioned problem exists in patent (CN222703142U); it describes "a hidden ambient light, including a housing, a circuit board, an inner lens and an outer lens, the outer lens and the housing together form a receiving cavity, the circuit board and the inner lens are both located in the receiving cavity, the inner lens is located between the circuit board and the outer lens, and the circuit board is provided with a light source, the outer surface of the outer lens is provided with a semi-transparent layer, the inner surface of the outer lens is provided with a hollow layer, and the outer surface of the inner lens is provided with a first pattern. When the circuit board controls the light source to emit light, the light rays are reflected and refracted through the first pattern on the inner lens, forming multiple beams of high-brightness light of different intensities. Some of the high-brightness light rays are transmitted through the hollow area of ​​the hollow layer to obtain a light effect similar to a starry sky." The hidden ambient light in the above patent is mainly used in the interior roof of a car. The inner lens and the outer lens are both planar structures, and can generally only be used on planar structures. They are not suitable for the special arc shape of the car door handle and cannot be well applied to the curved interior door handle of a car.

[0005] The existing starry sky effect ambient lights are generally used for car interior roof decorations and are relatively large, which is not suitable for the special curved surface shape of car door handles and cannot be applied to the interior door handles. The current car door handle lighting solutions are usually one or more single white light beads, which are directly lit or slowly light up and turn off, and can only provide illumination to the handle area.

[0006] Therefore, a light-shielding ambient light structure for the interior of the car door handle is proposed to address the above problems. Utility Model Content
