Description

Technical Field

[0001] This invention relates to the field of automotive ambient lighting technology, and in particular to an automotive dashboard ambient light. Background Technology

[0002] Ambient lighting, as an auxiliary lighting system, is increasingly being used in automotive trim such as the dashboard, door panels, and headliner. It typically takes the form of point light sources, strip light sources, and area light sources, with single-color and multi-color options available. By arranging a set of light strips and components in each area requiring illumination, different lighting atmospheres are achieved, creating a comfortable interior environment. However, as the number of ambient lights increases, the number of light strips and components also increases significantly, leading to a substantial increase in component cost and weight, as well as increased installation difficulty. This does not align with the current mainstream trend of low-carbon and green development in the automotive industry.

[0003] For example, Chinese patent CN111762091A discloses an ambient light for a car door panel. The ambient light strip is set on a snap-fit ​​structure that protrudes into the car from the lower body of the door panel. The ambient light strip is covered by an electroplated trim strip in the direction inside the car, and the electroplated trim strip and the snap-fit ​​structure are kept at a certain safe distance. The lower edge of the electroplated trim strip bends towards the car door, and a gap is formed between the edge of the bend and the single layer of leather applied to the surface of the trim panel in the door panel. The ambient light shines through the gap onto the single layer of leather to create a halo effect. The luminous atmosphere is uniform. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] The automotive dashboard ambient light includes a dashboard frame, an ambient light bracket, and an ambient light strip. The ambient light bracket is a light-transmitting bracket, positioned on the dashboard frame and partially extending out of it. The ambient light strip is installed inside the ambient light bracket. The extended portion of the ambient light bracket includes a visible portion and a downward-facing invisible portion. The light from the ambient light strip shines from the visible portion to form a direct light-emitting area, and the light from the invisible portion shines onto the dashboard components to form a reflective light-emitting area.

[0007] Further:

[0008] The instrument panel frame has an inwardly turned-up edge on its side, and the main body of the instrument panel frame has a gap area corresponding to the inwardly turned-up edge area for the ambient light bracket to extend out.

[0009] The ambient light bracket is a semi-milky white strip bracket with a light transmittance of more than 70%, and the ambient light strip is arranged along the length of the ambient light bracket.

[0010] The ambient light bracket has a horizontal slot on its inner side, and the ambient light strip is positioned and snapped into place within the horizontal slot.

[0011] The instrument panel frame is provided with a main positioning pin and an auxiliary positioning pin arranged in a staggered manner. The ambient light bracket is provided with a positioning hole that matches the positioning pin. The ambient light bracket is fixed to the instrument panel frame by screws.

[0012] The ambient light bracket has a mating groove on its side that fits with the flange of the dashboard frame. The lower front face of the mating groove forms a visible part, and the upper part of the mating groove extends outward, with a snap-fit ​​structure for positioning.

[0013] Below the gap area are a decorative panel and an air vent knob. Light shines from the invisible part onto the surface of the decorative panel and the air vent knob to form a reflective light-emitting area.

[0014] The lower surface of the invisible part of the ambient light bracket is a horizontal plane.

[0015] The central axis of the positioning pin is perpendicular to the length direction of the ambient light bracket.

[0016] The instrument panel frame is provided with a skin, and the skin at the inner flange is located in the mating groove.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] The ambient lighting structure of this car dashboard is reasonably designed, achieving both direct and reflective lighting effects through a single light strip, resulting in diverse ambient lighting effects; moreover, the structure is simple, easy to assemble, and securely and reliably installed.

[0031] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0032] like Figures 1 to 9 As shown, the car dashboard ambient light includes a dashboard frame 1, an ambient light bracket 2, and an ambient light strip 4. The dashboard frame 1 is a hollow frame structure, the ambient light bracket 2 is a light-transmitting bracket, the lower part of the dashboard frame has a gap, and the ambient light bracket is positioned on the dashboard frame and partially extends out from the gap of the dashboard frame.

[0033] The ambient light strip 4 is installed inside the ambient light bracket 2, integrated and compact in structure; the extended part of the ambient light bracket includes a visible part and a downward invisible part. The front end of the downward extended part of the ambient light bracket is the visible part, and the lower surface of the downward extended part of the ambient light bracket is the part that the occupants cannot see directly; the light from the ambient light strip shines from the visible part to form a direct light-emitting area 3, and the light from the invisible part shines onto the dashboard components to form a reflective light-emitting area 5.

[0034] The present invention provides a reasonable design for the automotive dashboard ambient light structure. It achieves both direct and reflective lighting effects through a single light strip, resulting in diverse ambient light effects. Furthermore, the structure is simple, easy to assemble, and securely and reliably installed.

[0035] The ambient light bracket 2 is a semi-milky white strip bracket with a light transmittance of more than 70%. The ambient light strip 4 is arranged along the length of the ambient light bracket. The ambient light strip is a rigid light strip, and the ambient light bracket is a transparent component. The light strip is directly integrated and positioned on the ambient light bracket, resulting in a compact structure.

[0036] The instrument panel frame 1 has an inwardly turned-up edge on its side. The main body of the instrument panel frame has a gap area corresponding to the inwardly turned-up edge area for the ambient light bracket to extend. One side of the ambient light bracket is stuck inside the inwardly turned-up edge, resulting in a compact structure. The inwardly turned-up edge effectively improves the structural strength of the frame.

[0037] The ambient light bracket has a mating groove on its edge that mates with the flange of the dashboard frame. The lower front face of the mating groove forms a visible part, and the upper part of the mating groove extends outward. The extended part has a snap-fit ​​structure for positioning, resulting in a compact structure. The mating groove of the ambient light bracket and the inner flange of the dashboard frame are connected in a concealed manner, so that the mating part cannot be seen by the occupants, thus improving the quality of the product.

[0038] The dashboard frame is equipped with a PVC skin 101 and a three-dimensional mesh fabric 102. The skin at the inner edge is located in the mating groove. The skin edge can be squeezed and positioned by the mating groove of the ambient light bracket. The structural stability and reliability are improved by its own mating structure.

[0039] Below the gap area are the decorative panel and the air vent knob 6. Light shines from the invisible part onto the surface of the decorative panel and the air vent knob to form a reflective luminous area. The lower surface of the invisible part of the ambient light bracket is a horizontal plane. For example, at the position of the air outlet blade 7, the upper surface of the air vent knob 6 corresponds to the lower surface of the ambient light bracket, forming an air vent knob illumination area 601 on the upper surface of the air vent knob, creating a variety of atmospheric effects.

[0040] The ambient light bracket has a horizontal slot on its inner side, and the ambient light strip is snapped into place within the horizontal slot. The instrument panel frame has a main locating pin 8 and an auxiliary locating pin 9 arranged in a staggered manner. The ambient light bracket has locating holes that match the locating pins. The ambient light bracket is fixed to the instrument panel frame by screws. The central axis of the locating pin is perpendicular to the length direction of the ambient light bracket.

[0041] The instrument panel ambient lighting arrangement of this invention enables a single light strip to simultaneously achieve both direct and reflective lighting effects; it is securely installed, has better light transmission consistency, a simple structure, is easy to install, and has a novel form, ensuring the effects of both direct and reflective lighting.

[0042] The automotive dashboard ambient lighting assembly includes an ambient light strip and an ambient light bracket mounted on the dashboard. The ambient light strip and the ambient light bracket are snap-fit ​​connected. The ambient light bracket and the dashboard frame are screwed and pre-snap-fitted. The dashboard frame has a main locating pin and an auxiliary locating pin. The ambient light bracket assembly has a main locating hole into which the main locating pin is inserted and an auxiliary locating hole into which the auxiliary locating pin is inserted.

[0043] The ambient light bracket is milky white with a light transmittance of 75%. The bracket has multiple screw fastening points along the length of the ambient light; the screws are arranged sequentially at intervals of 100mm-120mm; a total of 5 screw fastening points are provided.

[0044] The width of the reflective surface of the ambient light bracket is 20.18mm; the width of the direct reflective surface of the ambient light bracket is 2.2mm; the length of the reflective surface of the ambient light bracket is 565.1mm; the wall thickness of the reflective surface of the ambient light bracket is 2.5mm; the projected area of ​​the reflective surface of the reflective ambient light is 14311.388 square millimeters; the projected area of ​​the reflective surface of the direct ambient light is 1657.923 square millimeters.

[0045] The direct and reflective ambient light materials are made of translucent PC material, which requires 90°C & 2H annealing treatment to remove the internal stress of the PC ambient light trim strip and prevent stress release that could cause cracking. The automotive dashboard ambient light assembly of this invention is securely installed and has better light transmission consistency, ensuring the effects of both direct and reflective lighting.
