Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] The purpose of this invention is to provide a meteor light and shadow module for automotive sunshades and an automotive vehicle, in order to solve the problems existing in the prior art, realize modular mass production, and improve quality stability and production efficiency.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1 This embodiment provides a meteor light and shadow module for automotive sunshades, such as Figures 1-3As shown, it includes: a meteor light guide cloth 2, comprising a light-blocking fabric layer and a light guide layer 5 laid in layers from top to bottom, at least one edge of the light guide layer 5 being exposed, and multiple light-emitting holes 8 being provided on the light guide layer 5, the multiple light-emitting holes 8 forming a straight line or an arc on the light guide layer 5, the light guide layer 5 being used to fix it above the sunshade curtain 7, and the sunshade curtain 7 being provided with light-leaking holes 9 corresponding one-to-one with the light-emitting holes 8; a strip light emitter group 10, comprising a control circuit board and multiple LEDs disposed on the circuit board, the multiple LEDs being opposite to the exposed edge of the light guide layer 5, the control circuit board being able to control the multiple LEDs to light up sequentially along the edge direction of the light guide layer 5, and when the next LED is lit, the adjacent previous LED is turned off. The light-emitting holes 8 of the light guide layer 5 are arranged in straight lines or arcs. Combined with the control logic of the control circuit board to "light up the LEDs sequentially and turn off the headlights as the taillights turn off," light can pass through the corresponding light-leaking holes 9 along a fixed trajectory, accurately simulating the dynamic trajectory of a meteor streaking across the sky. Through standardized and modular design, the meteor light guide cloth 2 and the strip-shaped light emitter assembly 10 can be prefabricated in the factory, significantly reducing manual operations and improving production efficiency. Furthermore, in the modular production mode, all components follow unified technical standards, avoiding inconsistencies in light and shadow effects and installation size deviations caused by human error during manual production. This ensures that the meteor trajectory and light emission rhythm of each module are consistent, guaranteeing product quality stability and consistency, while also reducing subsequent quality inspection and rework costs. The modular design of the meteor light and shadow module 1 eliminates the need for significant modifications to the original sunshade 7 structure. The light guide layer 5 can be directly fixed on top of the existing sunshade 7, and the strip-shaped light emitter assembly 10 only needs to be installed on the sunshade 7 frame opposite the exposed edge of the light guide layer 5. More preferably, the strip light emitter group 10 is an RGB meteor light strip module. In a further preferred embodiment of this invention, the meteor light and shadow module 1 for the car sunshade also includes a mounting base 11. One end of the strip-shaped light emitter assembly 10 and the meteor light guide cloth 2 are both fixedly mounted on the mounting base 11. The mounting base 11 is used to fix it to the rear retractor 12 of the sunshade 7 frame or to the front pull plate of the sunshade 7 frame. The design of the mounting base 11 allows the strip-shaped light emitter assembly 10 to be integrated into a small assembly unit on the mounting base 11 without being fixed separately, and then installed as a whole onto the rear retractor 12 or the front pull plate, which facilitates installation and fixation.

[0021] In a further preferred embodiment of this invention, the mounting base 11 is used to fix itself onto the rear roller shaft 12 of the sunshade curtain 7 frame. The rear roller shaft 12 has an opening 13 along its axial direction for inserting the sunshade curtain 7 and the meteor light guide cloth 2. The mounting base 11 is fixed inside the rear roller shaft 12. With the mounting base 11 fixed to the rear roller shaft 12, the strip light emitter assembly 10 rotates synchronously with the roller shaft when the sunshade curtain 7 is rolled up. Since the edge of the light guide layer 5 and the LED light always maintain a relative position, the light and shadow interruption caused by the misalignment of the light source and the light guide layer 5 during the rolling process can be avoided, allowing the meteor effect to be continuously and stably presented throughout the entire rolling and unfolding process of the sunshade curtain 7.

[0022] In a further preferred embodiment of this invention, the rear rewind spool 12 further includes a conductive slip ring. The conductive slip ring is disposed within the rear rewind spool 12, with its rotor fixedly connected to the rear rewind spool 12. The rotor lead of the conductive slip ring is connected to the strip-shaped light-emitting unit 10, and the stator lead of the conductive slip ring passes through the rear rewind spool 12 and connects to the vehicle control system. The rotor of the conductive slip ring rotates synchronously with the rear rewind spool 12, while the stator remains stationary. Continuous electrical conduction and signal transmission during rotation are achieved through the sliding contact between the brush and the conductive ring within the stator. The conductive slip ring eliminates the need for the power and control lines of the strip-shaped light-emitting unit 10 to wind around the rewind spool, fundamentally avoiding the risk of line wear and breakage. This ensures that the meteor light effect of the sunshade 7 remains stable and uninterrupted during repeated rewinding and unfolding, without any flickering or interruptions.

[0023] In a further preferred embodiment of this invention, the light-blocking fabric layer includes a base fabric 3 and a light-blocking film 4. The light-blocking film 4 is located between the base fabric 3 and the light-guiding layer 5. The base fabric 3 and the light-blocking film 4 are bonded and fixed together, and the light-blocking film 4 and the light-guiding layer 5 are bonded and fixed together. The light-guiding layer 5 is bonded above the sunshade curtain 7. Applying adhesive evenly to the surfaces of the base fabric 3, the light-blocking film 4, and the light-guiding layer 5 allows for quick and easy bonding and fixing, significantly shortening assembly time and improving installation efficiency.

[0024] In a further preferred embodiment of this invention, the meteor light guide cloth 2 is rectangular in shape and has light guide fibers 6. The ends of the light guide fibers 6 are exposed from the short side of the meteor light guide cloth 2 and are positioned opposite to the LED lights.

[0025] In a further preferred embodiment of this invention, the end of the light guide fiber 6 at the light exit hole 8 can be bent away from the light-shielding fabric layer to form a bent portion, which is perpendicular to the light-shielding fabric layer. The perpendicularity of the bent portion of the light guide fiber 6 to the light-shielding fabric layer allows light to exit from the light exit hole 8 in a direction perpendicular to the fabric layer, precisely controlling the light emission direction and improving light utilization efficiency. The perpendicular emission method can concentrate the light towards the target area, improving the directionality and concentration of the illumination. Preferably, the end of the light guide fiber 6 can be bent manually.

[0026] Example 2 This embodiment provides a car, including the meteor light and shadow module 1 for car sunshade of embodiment 1.

At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model.
