Description

Automotive interior star sky apron and car roof Technical Field The invention relates to an automobile interior star sky cover plate and an automobile ceiling, and belongs to the technical field of automobile star sky roofs. Background The starry sky roof is a luminous ceiling. The ceiling emits light, such as a star point, such as meteor flash, so that a dynamic optical effect is brought to the automotive interior ceiling, and the automotive interior ceiling is favored by a plurality of car owners. The star roof is generally made of optical fibers, one end of each optical fiber is connected with an optical machine, and the other end of each optical fiber is exposed out of the front surface of the ceiling and trimmed to be in a state of being flush with the ceiling fabric. Light emitted by the optical machine is conducted to the surface of the top shed through the optical fiber, so that a starry sky effect is formed. The current star-sky roof has the problem of optical fiber hand pricking. This is because the optical fiber is trimmed to create a sharp edge, and when the ceiling surface is pressed with a finger, the ceiling fabric sags and the optical fiber pricks the finger. This poor experience also reduces the level of the star top. In addition, the assembly of the optical fibers is a time-consuming and labor-consuming task, wherein first, the optical fiber holes are made in the ceiling, then one optical fiber passes through the optical fiber holes, then the optical fibers are fixed by glue on the back surface, and the optical fibers are trimmed on the front surface. The same procedure is required for each fiber, and if the spot has special requirements, the fiber is required to correspond to the light hole, which is more complicated. The number of the optical fibers is generally not less than 300, so that the production efficiency of the star-sky roof is low, and the mass production is difficult. Also, the optical fiber has a minimum bending radius, and if the bending degree is too large, light leakage phenomenon occurs beyond the bending radius, even causing breakage of the optical fiber. Therefore, the back of the ceiling must leave room for the optical fibers, and this thickness is usually not less than 15mm. In a new energy automobile, because the bottom space of the automobile is occupied by a battery, the top space of the automobile is particularly expensive, and many automobile types cannot leave so much top space, so that the starry sky roof cannot be applied. Therefore, an automotive interior star sky cover plate and an automotive ceiling are urgently needed in the industry, and the problems of hand pricking, low efficiency, large space occupation and the like of the existing optical fibers can be solved. Disclosure of Invention Aiming at the defects of the prior art, the invention provides an automotive interior star-sky cover plate and an automotive ceiling adopting the automotive interior star-sky cover plate. The technical scheme includes that the automobile interior starry sky cover plate comprises a starry sky cover plate framework, a plurality of circuit boards arranged on the passenger side of the starry sky cover plate framework and a light-transmitting surface layer arranged on the surfaces of the starry sky cover plate framework and the circuit boards, wherein the circuit boards are in strip-shaped shapes, the circuit boards are flexible circuit boards or hard circuit boards, a plurality of LED light-emitting elements are arranged on the circuit boards, the LED light-emitting elements adopt Mini LEDs, and the automobile interior starry sky cover plate further comprises a filling layer arranged on the back surface of the light-transmitting surface layer, and the filling layer is arranged on the surfaces of the circuit boards or the surfaces of the starry sky cover plate framework and the circuit boards. The invention has the beneficial effects that the transparent surface layer is adopted, the visible surface of the cover plate can realize light emission without punching, and the appearance of the existing star-sky roof is improved. The LED below the light-transmitting surface layer is used as a light-emitting element, and compared with the traditional star-sky roof, each light spot corresponds to an independent light-emitting element, so that the color and the brightness of each light spot can be controlled as required. The circuit board with the strip-shaped appearance can adopt a hard circuit board, so that the shape difference of the circuit board is smaller when the circuit board is adhered to the starry sky cover plate framework. If a circuit board with larger length and width dimensions is used, the circuit board is in a plane shape, the starry sky cover plate skeleton corresponds to the shape of the automobile body, and is in a curved surface shape, and the two shapes are different, so that the circuit board and the starry sky cover plate skeleton cannot be flatly attached.
