[0053] The technical solution of the present utility model will be further described in conjunction with the following embodiments.

[0054] Embodiment 1

[0055] A multifunctional optical lens 10, as Figures 1 to 5As shown, a lens body 100 and multiple conduction ribs 200 are provided. The side where the external light source is located is correspondingly defined as the rear end and the front end of the multifunctional optical lens 10. The conduction ribs 200 are integrally connected to the side surface of the lens body 100 and extend from the rear end to the front end. The lens body 100 is provided with a closed hole 120. The central axis of the closed hole 120 overlaps with the median line of the lens body 100, and the opening of the closed hole 120 is located at the rear end of the lens body 100. The rear end of the conduction rib 200 is provided with a forked structure 210, and the opening of the forked structure 210 is located at the rear end. The side wall of the lens body 100 is provided with a compound eye structure layer 110. The lens body 100 is provided with multiple protrusions 130, and the protrusions 130 are integrally connected to the bottom of the closed hole 120.

[0056] In the present utility model, the height of the lens body 100 is defined as H, and 15mm ≤ H ≤ 30mm; the maximum width of the front end of the lens body 100 is defined as L1, and 25mm ≤ L1 ≤ 50mm; the maximum width of the rear end of the lens body 100 is defined as L2, and 10mm ≤ L2 ≤ 20mm; the depth of the closed hole 120 is defined as S, and 5mm ≤ S ≤ 12mm; the inner diameter of the closed hole 120 is defined as D, and 10mm ≤ D ≤ 15mm, as Figure 6 shown. From the rear end to the front end direction, the maximum width of the cross-section of the lens body 100 gradually increases. Moreover, there is at least one cross-section in the lens body 100 whose shape is circular, as Figure 7 and Figure 8 shown.

[0057] It should be noted that through multiple experimental verifications, when the size of the multifunctional optical lens 10 of the present utility model increases, the multifunctional optical lens 10 will shrink during molding, and the arrangement difficulty of the multifunctional optical lens 10 increases; when the size decreases, the distance between the multifunctional optical lens 10 and the light source 800 decreases, affecting the irradiation effect. Therefore, only when the size is within the above range, the production and irradiation effect of the multifunctional optical lens 10 are both good, Figure 9 and Figure 10 .

[0058] It should be noted that the shapes of all cross-sections of the lens body 100 of the present utility model are circular, that is to say, the lens body 100 can be in the shape of a frustum of a cone as a whole; the lens body 100 can also be an irregular three-dimensional structure with only some cross-sections being circular. Specifically, the front end face of the lens body 100 is of other shapes, such as a circular shape with a notch, and the rear cross-section is circular; of course, the lens body 100 can also be other three-dimensional structures, which can be determined according to the actual situation. This embodiment is described by taking the frustum of a cone structure as an example.

[0059] The multifunctional optical lens 10 of the present utility model is further provided with an assembly ring 400 and at least two support feet 500. The assembly ring 400 is integrally connected to the outer periphery of the rear end of the lens body 100; a heat dissipation hole 300 for heat dissipation is further provided between the assembly ring 400 and the lens body 100. The support feet 500 are integrally connected to the rear end face of the lens body 100.

[0060] It should be noted that the function of the assembly ring 400 is to fix the lens body 100 to the external vehicle driving lamp 20. The function of the heat dissipation hole 300 is to radiate the heat generated by the light source 800 to the outside through the heat dissipation hole 300. The function of the support feet 500 is to keep a gap between the lens body 100 and the light source 800. The functions of the conduction edges 200 and the closed holes 120 of the present utility model are to enable the optical lens to have different lighting effects through light refraction. Moreover, the functions of the fork structure 210, the compound eye structure layer 110 and the protrusions 130 are to further improve the optical performance of the multifunctional optical lens 10.

[0061] The multifunctional optical lens 10 can be adapted to a variety of light sources 800 to achieve lighting effects such as high beam lights, daytime running lights, position lights or ambient lights. Compared with the prior art, it can reduce the number of lenses of the driving lamp, simplify the structure of the driving lamp, and reduce the volume and weight of the driving lamp.

[0062] Embodiment 2

[0063] A multifunctional optical lens 10, as Figures 11 to 13 shown, other features are the same as those in Embodiment 1. The difference is that only part of the cross-section of the lens body 100 in this embodiment has an irregular three-dimensional structure with a circular shape. Specifically, the front end face of the lens body 100 is a circle with two notches, and the front cross-section is circular, as Figures 14 to 16 shown. Moreover, the bottom of the closed hole 120 in this embodiment is a plane, and no protrusion 130 is provided.

[0064] Compared with Embodiment 1, the multifunctional optical lens 10 in this embodiment can reduce the maximum width of the rear end face, which is convenient for arrangement in the driving lamp.

[0065] Comparative Example 1

[0066] An optical lens, other features are the same as those in Embodiment 1, as Figure 17 shown. The difference is that the lens body does not have conduction edges and closed holes.

[0067] Effect Example

[0068] Under the condition that other conditions are the same, the lighting effects of the optical lenses of Embodiment 1, Embodiment 2 and Comparative Example 1 without being paired with high beam light sources, daytime running light sources, position light sources and ambient light sources are shown in Table 1.

[0069] Table 1. Effect Table of Different Light Sources of the Optical Lenses in Example 1, Example 2 and Comparative Example 1

[0070] Number Light source type Example 1 Example 2 Control Example 1 1 High beam light source Good effect Good effect Poor effect 2 Daytime running light source Good effect Good effect Good effect 3 Position light source Good effect Good effect Poor effect 3 Ambient light Good effect Good effect Poor effect

[0071] As can be seen from Table 1, the multifunctional optical lens of the present utility model can be adapted to the high beam light source, daytime running light source, position light source, and ambient light source, and achieve the lighting effects of high beam lights, daytime running lights, position lights, and ambient lights. At the same time, compared with the optical lens of Comparative Example 1, the combination of the conduction edges 200 and the closed holes 120 of the present utility model does enable the multifunctional optical lens 10 of the present utility model to have different lighting effects simultaneously.

[0072] Example 3

[0073] A vehicle driving lamp 20, as Figure 18 and Figure 19 , is provided with a bottom plate 700, a multifunctional optical lens 10 as in Example 2, and a plurality of light sources 800. The light sources 800 are assembled on the bottom plate 700, the multifunctional optical lens 10 is disposed on the bottom plate 700, and the plurality of light sources 800 are located in the rear end region of the multifunctional optical lens 10.

[0074] The light source 800 is at least one of a daytime running light source 800, a high beam light source 800, a position light source 800, or an ambient light source 800.

[0075] It should be noted that as long as the light source 800 of the present utility model is located behind the multifunctional optical lens 10, light can enter the interior of the multifunctional optical lens 10 from the rear side wall of the lens body 100 of the multifunctional optical lens 10, the closed hole 120, or the surface of the conduction edge 200 and be refracted inside, thereby achieving the corresponding illumination effect. Moreover, the present utility model can select the type of the light source 800 according to actual needs, such as one or more of a daytime running light source 800, a high beam light source 800, a position light source 800, or an ambient light source 800. For example, when the multifunctional optical lens 10 is combined with the daytime running light source 800, the illumination effect of the daytime running light can be achieved; when the multifunctional optical lens 10 is combined with the high beam light source 800, the illumination effect of the high beam light can be achieved; when the multifunctional optical lens 10 is combined with the position light source 800, the illumination effect of the position light can be achieved; when the multifunctional optical lens 10 is combined with the ambient light source 800, the illumination effect of the ambient light can be achieved, and the illumination effect of the multifunctional optical lens 10 corresponds to the type of the light source 800.

[0076] By using the multifunctional optical lens 10, the vehicle driving lamp 20 can achieve the lighting effects of high beam, daytime running lamp, position lamp, and atmosphere lamp in cooperation with different external light sources 800. Therefore, the number of lenses of the driving lamp can be reduced, the structure of the driving lamp can be simplified, and the volume and weight of the driving lamp can be reduced.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
