[0022] In order to more clearly describe the technical content of the present utility model, the following will be further described in conjunction with specific embodiments.
[0023] The thick-walled optical component structure for automobiles of the present utility model includes a main body, a group of light condensing structures and two light refracting and diffusing structures. The main body includes a thick-walled main body and a connecting side wall. One end of the connecting side wall is connected to one side of the lower surface of the thick-walled main body, and the other end of the connecting side wall is connected to one side of the light condensing structure. An intermediate hollow structure is formed among the thick-walled main body, the connecting side wall and the light condensing structure. Light refracting and diffusing structures are respectively arranged on the upper surface and the lower surface of the thick-walled main body, and an LED is placed in front of the light condensing structure.
[0024] As a preferred implementation manner of the present utility model, the light condensing structure includes 18 collimating lenses, the 18 collimating lenses are arranged at equal intervals on a plane, and the angles of the 18 collimating lenses enable the light of the LED to propagate along the X direction.
[0025] As a preferred implementation manner of the present utility model, the light refracting and diffusing structure is composed of a plurality of quadrilateral structures, and the surface of the quadrilateral structure is a curved surface with double curvature.
[0026] As a preferred embodiment of the present utility model, the 18 collimating lenses are arranged equidistantly at an interval of 9.6 mm.
[0027] As a preferred embodiment of the present utility model, the maximum thickness of the thick-walled main body is 11 mm, and the maximum thick-walled depth is 26 mm.
[0028] In the specific embodiment of the present utility model, the purpose is to overcome the above-mentioned disadvantages in the prior art, and provide an optical solution with low cost and high uniformity to meet the requirements of customers.
[0029] The present utility model provides a thick-walled optical component that emits light from the bottom surface, then has a hollowed-out middle structure, the light is scattered for the first time through the middle surface, then scattered for the second time through the top surface, and finally the light is evenly emitted through an external light distribution lens.
[0030] The structure of the thick-walled optical component for automobiles includes a set of light condensing structures and two light refracting and scattering structures, and the middle part between the light condensing and light refracting and scattering structures is hollowed out.
[0031] The light condensing structure is composed of multiple collimating lenses that collect LED light and simultaneously change the propagation direction of the light, so that all the light propagates in the X direction;
[0032] The light refracting and scattering structure is composed of multiple quadrilateral (1 mm × 1 mm) structures, and its function is to evenly refract the light according to the required viewing angle, so that the overall light effect appearance looks more uniform.
[0033] Key dimensions of the thick-walled component: maximum thickness 11 mm, maximum thick-walled depth 26 mm, (meeting the requirements for one-shot injection molding of the thick-walled component).
[0034] The product forming process is one-shot injection molding by a special injection molding machine for thick-walled components.
[0035] The middle hollowed-out structure reduces the material used for the product, enables one-shot injection molding, reduces the risk of injection shrinkage printing of the product. In the past, thick-walled components needed to use layered injection molding, which made the mold structure complex, the cost higher, and the yield rate low. Adding a light refracting and scattering structure in the middle makes the light effect more uniform.
[0036] The light condensing structure is composed of 18 collimating lenses arranged equidistantly in a straight line at an interval of 9.6 mm, as Figure 3 shown. Working principle of the collimating lens: collect the non-parallel light emitted by the LED, through the principles of light reflection and refraction, turn it into parallel light inside the lens, and then refract it through a certain angle surface when coming out according to optical needs to become the effective light required by optics.
[0037] As Figure 4 and Figure 5As shown, the main functional surface of the quadrilateral is a curved surface with a two-way radian. Tens of thousands of such curved surfaces are arranged together according to optical requirements to form a refractive and diffractive structure.
