[0035] An embodiment of the present utility model provides a structure of a D - pillar trim panel with a charging indicator light for an automobile.

[0036] As Figures 1-14As shown in the figure, a structure of a D-pillar decorative panel with a charging indicator light for an automobile includes a decorative panel base 1. The decorative panel base 1 is arranged on the D-pillar surface of the automobile. There are a sunken area and an outer shell plate on the surface of the decorative panel base 1. There is a height difference between the sunken area and the outer shell plate. The sunken area is lower than the plate surface of the outer shell plate. The outer shell plate is a smooth panel. There are several piercing welding points 101, a buckle anti-detachment structure 102 and a hot melt rib 103 on the sunken area. There is an electroplated decorative panel 2 arranged on the decorative panel base 1 and matching the sunken area. There are buckles and hot melt rib positioning plates on the back panel of the electroplated decorative panel 2. The buckles and hot melt rib positioning plates are installed in matching correspondence with the buckle anti-detachment structure 102 and the hot melt rib 103 on the sunken area of the decorative panel base 1. There is a triangular smooth surface 201 on the front of the electroplated decorative panel 2. The triangular smooth surface 201 is composed of convex triangular pyramids. The material of the electroplated decorative panel 2 is composed of PC + ABS. The thickness of the electroplated decorative panel 2 is 3 mm. Each surface of the triangular smooth surface 201 is polished to better display the bright color. There is a laser engraving mask 7 on the side of the decorative panel base 1. There is a fast-protruding light-transmitting area 703 on the side of the laser engraving mask 7. The laser engraving mask 7 is integrally formed into an L-shaped plate surface. There are clamping buckles 701 and connecting and fixing parts 702 on both sides of the laser engraving mask 7 for fixing with the decorative panel 1 and the vehicle body. There is a light-emitting component arranged inside the laser engraving mask 7. The inside of the light-transmitting area 703 on the side of the laser engraving mask 7 is directly opposite to the light-emitting surface of the light-emitting component. The outside of the light-transmitting area 703 on the side of the laser engraving mask 7 is directly opposite to the triangular smooth surface 201 of the electroplated decorative panel 2 arranged on the decorative panel base 1. The light emitted by the light-emitting component passes through the light-transmitting area 703 on the side of the laser engraving mask 7 and irradiates on the triangular smooth surface 201 of the electroplated decorative panel 2. The light irradiated on the triangular pyramids on the triangular smooth surface 201 is refracted and reflected with each other to further amplify the brightness. In order to distinguish the light-transmitting surface and at the same time enhance the light-transmitting effect, the laser engraving mask 7 is integrally injection-molded with PC milky white and then the inside is sprayed with opaque black paint, and then the light-transmitting area 703 is laser-engraved, and finally UV varnish is applied to protect the inside of the laser engraving mask 7. Because of the opaque black paint sprayed in other areas, the light emitted by the light-emitting component will not penetrate. The inner side of the panel on the side of the light-transmitting area 703 is an opaque area, reducing the light penetration and improving the light-transmitting effect.

[0037] There is a light-emitting component inside the laser-engraved mask 7. The light-emitting component includes a light homogenizing panel 4, a printed circuit board assembly 5, a lamp group base 6, and a wire harness assembly 8. The light-emitting component is formed by snap-fitting and splicing the light homogenizing panel 4 and the lamp group base 6 up and down. The light homogenizing panel 4 and the lamp group base 6 are ultrasonically welded to meet the functions of waterproofing and dustproofing. A layer of foam 3 is wrapped and adhered at the connection of the outer shells of the light homogenizing panel 4 and the lamp group base 6, which plays a role in firmly installing the light homogenizing panel 4 and the lamp group base 6 up and down, preventing abnormal noises caused by the shaking of the installation parts of the light homogenizing panel 4 and the lamp group base 6, and at the same time ensuring the sealing performance at the connection of the light homogenizing panel 4 and the lamp group base 6. A light-transmitting surface is provided on the surface of the light homogenizing panel 4, through which light can pass through. The light homogenizing mask is injection-molded in the natural color of milky white PC material with a wall thickness of 2.5 mm. The overall shape of the lamp group base 6 is matched with the light homogenizing panel 4 in terms of corresponding size. There are three sealing holes provided at the bottom of the lamp group base 6, which are blocked by sealing plugs. There is also a circular wire harness inlet provided on the lamp group base 6. A card slot is provided inside the lamp group base 6, and a printed circuit board assembly strip 5 is arranged in the internal card slot of the lamp group base 6. The printed circuit board assembly strip 5 is a PCBA light-emitting strip. The PCBA light-emitting strip adopts a 2-mm-thick thickened copper foil solution to improve the heat dissipation ability of the lamp beads. At the same time, the PCBA light-emitting strip is evenly distributed with 36 PCS RGB LEDs on the light-emitting strip to meet the function of multi-color lighting. A total of 4 colors can be displayed, namely green, yellow, red, and blue. A power connection port is provided on the printed circuit board assembly strip 5 and is connected to an external power supply for power supply. A wire harness assembly 8 is provided on the printed circuit board assembly strip 5. As Figure 8 shown, it is a structural schematic diagram of the wire harness assembly 8. A plug 9 is provided in the middle of the wire harness assembly 8. Power connection heads 11 and circuit board connection heads 12 are provided at both ends of the wire harness assembly 8. The circuit board connection head 12 is connected to the power connection port arranged on the printed circuit board assembly strip 5. The power connection head 11 is connected to an external power supply. At the same time, the plug 9 is arranged at the wire harness inlet on the lamp group base 6. The setting of the plug 9 plays a sealing role to prevent water from penetrating into the lamp group base 6 and causing a short circuit of the circuit board.

[0038] Working principle: A lighting component is provided on the side of the trim base 1 and is wrapped by a laser-engraved mask 7. The laser-engraved mask 7 is divided into a light-transmitting area and a non-light-transmitting area. The light emitted by the lighting component is irradiated onto the triangular light surface 201 of the electroplated trim 2 on the trim base 1 through the light-transmitting area. The light irradiated on the triangular light surface 201 is magnified and displayed on the entire triangular light surface 201 through refraction and reflection. The wire harness assembly 8 is connected to an external power supply circuit board, and the external power signal is transmitted to the printed circuit board assembly strip 5 through the wire harness assembly 8, enabling the corresponding RGB LEDs on the printed circuit board assembly strip 5 to emit light and be displayed on the electroplated trim 2, allowing users to see the charging status outside the straight pipe. Moreover, the storage temperature range of the lighting component is -40°C to 100°C, and the operating temperature range is -40°C to 70°C, enabling continuous normal operation. When the vehicle is charging the power battery, relevant information is indicated, and four states are intended to be displayed: charging completed, charging waiting, charging failure, and external discharging. The charging indicator can display 4 colors, namely green, yellow, red, and blue. In the vehicle's parked charging state, it can be lit to emit the corresponding color to visually remind the charging status. The utility model has strong formability and assemblability, and meets the requirements of the D-pillar trim with a charging indicator for aesthetic functions and disassembly and assembly. This structural design can be standardized. The utility model is convenient to manufacture and suitable for large-scale industrial production.
