[0018] Below, with reference to the accompanying drawings, through the description of the embodiments, the specific implementation methods of the present invention, such as the shape, structure, relative positions and connection relationships of the various components involved, the functions and working principles of the various parts, the manufacturing process and operating methods, etc., are further explained in detail to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.
[0019] The core of the in-car ambient light system is to set up multiple light boards, each of which is evenly and densely distributed with light beads, preferably in a matrix distribution. In this way, the light board is similar to a low-pixel display screen, which can display different graphics and effects according to any custom program, thereby achieving a pleasant driving experience for the driver and passengers.
[0020] The light panels consist of multiple panels mounted in various locations, including the center console panel mounted on the front instrument panel, the driver's door panel mounted inside the driver's door, the passenger door panel mounted inside the passenger door, the driver's and passenger's rear door panels mounted inside the rear doors, and the exterior skirt panels mounted on the exterior side skirts. This allows for a dynamic display both inside and outside the vehicle. The panels can be shaped as needed to avoid interference with other components, such as door handles and window switches; the overall design can be a single strip.
[0021] In order to facilitate installation and later maintenance and replacement, the light panel at each location can be spliced together by multiple units, such as Figure 2 As shown, if such a light board is broken, only local parts need to be replaced. The light board consists of a three-layer structure, including a mounting plate, lamp beads arranged on the mounting plate, and a transparent cover plate covering the outside of the mounting plate. The transparent cover plate is used to protect the internal lamp beads and hide the ugliness. The mounting plate is provided with mounting holes and / or snap-fit structures for fixing to the vehicle body. The drive module is fixed on the light board, and the drive module is connected to each lamp bead on the light board to drive each action to work together to present different atmosphere effects.
[0022] Each of the light panels is connected to a controller, which is connected to the car multimedia system via the CAN bus and the LIN bus. The controller intelligently adjusts the lighting effect display based on the original car information received via the CAN bus and the LIN bus, combined with intelligent algorithms. Of course, the controller can also be connected to the sensor units on the car via the CAN bus and the LIN bus, such as the temperature sensors inside and outside the car, and the rain sensors outside the car. In this way, different atmosphere effects can be given by different temperatures. For example, a cool atmosphere can be given on a hot day to reduce the feeling of heat.
[0023] The lamp beads on the light board are multi-color LED light sources, and the driving module is an LED driving module. Through the multi-color lamp bead structure, combined with software intelligent algorithms, logical judgment and other methods, a simulated LED screen is realized, combining more than 30 different lighting effect animations, matching display scenes, and realizing intelligent switching. The simulated LED screen adopts a multi-lamp bead multi-drive mode, combined with the structural characteristics of the door panel, and the control algorithm drives the lamp beads. The side door side light panel is mainly displayed below, and other similar ones are not repeated. Of course, these control methods can be designed by yourself and are not the protection content of this utility model.
[0024] The driver module's driver end connects to each LED via a wiring harness. The module's power supply connects to the power module via a power cable. The module's input is connected to the vehicle's battery, and the module's signal input is connected to the SPI module. The controller uses the SPI bus to drive the LEDs, employing PWM to adjust brightness, color, and animation effects. Combining vehicle status information (sensors, motion, time, weather, multimedia, and more) with over 30 animation effects, the 32-bit MCU intelligently adjusts and switches to achieve fantastic effects.
[0025] The controller is equipped with a LIN module, a CAN module, an SPI module and an MCU. The communication end of the MCU is connected to the LIN module, the CAN module and the SPI module. The MCU is connected to the vehicle CAN bus and the LIN bus through the LIN module and the CAN module, and communicates with the original vehicle through the CAN / LIN bus to obtain the original vehicle's status information, temperature, time, multimedia, door movement, window movement and other information. The MCU communicates with the light board through the SPI module. The SPI bus intelligent drive algorithm can combine more than 30 kinds of animated lighting effects, and intelligently switch according to various information of the original vehicle, making the sensory experience non-monotonous and high-tech. The power module supplies power to the LIN module, CAN module, SPI module and MCU.
[0026] The ambient lighting system of this invention can simulate an LED screen, presenting a variety of different lighting effects and animations, matching display scenes, and realizing intelligent switching. The panel-style light board, combined with intelligent lighting effect switching, creates a dreamlike experience of nature, thus achieving a pleasant driving experience for drivers and passengers.
[0027] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
