Description

Electric automobile daylighting diffusion subassembly

Technical Field

The utility model belongs to the technical field of electric automobile accessory technique and specifically relates to an electric automobile daylighting diffusion subassembly is related to.

Background

The electric automobile is a new energy automobile, and the inner and outer decorative lamps of the electric automobile are white LEDs with uniform light sources and are arranged at automobile doorsills and the like. For example, when the user opened the door, the usher's footboard lamp appeared the bright luminous state to visible LOGO typeface just can carry out the customization of different typefaces according to customer's demand. However, many of these light sources are not uniform enough and have relatively complex structures.

Disclosure of Invention

The utility model aims at providing an electric automobile daylighting diffusion subassembly, it has the characteristics of simple structure, effect preferred.

The utility model adopts the technical proposal that: the daylighting diffusion component of the electric automobile comprises a light guide plate and a circuit board, wherein the circuit board is fixed at the left end of the light guide plate, a diffusion film is attached to the upper surface of the light guide plate, and an upper cover is arranged above the diffusion film.

The diffusion film comprises an anti-scratch layer, a transparent PET base layer and a diffusion coating layer, wherein the anti-scratch layer, the transparent PET base layer and the diffusion coating layer are arranged from bottom to top, and the diffusion coating layer is transparent micro spheres densely distributed on the surface of the transparent PET base layer.

Compared with the prior art, the utility model the advantage that has is: simple structure and better effect. The utility model discloses an electric automobile daylighting diffusion subassembly used part is less, and the structure is comparatively simple, but makes its light diffusion degree higher through the diffusion barrier, is convenient for enrich the stereovision of electric automobile interior exterior trim, makes the individual character atmosphere of brand oneself, promotes light and driver and crew's handing in mutual inductance.

Drawings

The invention will be further described with reference to the following figures and examples:

fig. 1 is an exploded perspective view of an electric vehicle lighting diffusing component according to an embodiment of the present invention;

fig. 2 is a front sectional view of the diffusion membrane of the present invention (enlarged compared to fig. 1).

In the figure:

10. a light guide plate;

20. a circuit board;

30. diffusion film, 31, anti-scratch layer, 32, transparent PET base layer, 33, diffusion coating.

Detailed Description

Examples, see fig. 1 and 2: the lighting diffusion component of the electric automobile comprises alight guide plate 10 and acircuit board 20, wherein thecircuit board 20 is fixed at the left end of thelight guide plate 10. Thecircuit board 20 itself is integrated with an LED light source, so that thecircuit board 20 can emit light when it is powered, and light is projected into thelight guide plate 10 from the left end of thelight guide plate 10.

Further speaking:

the upper surface of thelight guide plate 10 is attached with adiffusion film 30, and anupper cover 40 is disposed above thediffusion film 30. A certain distance should be provided between theupper cover 40 and thediffusion film 30, for example, the distance is 1-10 mm, and theupper cover 40 is provided with required characters or patterns by means of hollowing out or the like.

Thediffusion film 30 comprises an anti-scratch layer 31, a transparentPET base layer 32 and adiffusion coating 33 which are arranged from bottom to top. The scratch-resistant layer 31 is generally made of PMMA, and thediffusion coating 33 is a transparent microsphere densely distributed on the surface of thetransparent PET substrate 32. The transparent microspheres may have an average diameter in the range of millimeters to micrometers, for example, an average diameter of 30 μm to 1mm, and are prepared using a laser.

Thus, the light transmitted from thelight guide plate 10 is incident from the bottom anti-scratch layer 31, then penetrates through thetransparent PET substrate 32 with high transparency, and then is scattered by the transparent micro spheres forming thediffusion coating 33 to form an even surface light source, so that the light is ensured not to be directly emitted from thediffusion film 30, the atomization effect is achieved, and the effect is better.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the same way in the protection scope of the present invention.
