DETAILED DESCRIPTION

(11) Preferred embodiments of the present invention are described in greater detail below with reference to the accompanying drawings. Although preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be realized in various forms, and should not be restricted by the embodiments expounded here. On the contrary, these embodiments are provided in order to make the present invention more thorough and complete, and to enable the scope of the present invention to be conveyed to those skilled in the art in a complete fashion.

(12) According to an embodiment of the present invention, a light shielding structure 100, and a corresponding optical structure, vehicle lamp and vehicle are disclosed.

(13) Referring to FIGS. 3 to 5, the optical structure according to the present invention comprises a light shielding component 100, a light guide 200, and a supporting portion 300, wherein the supporting portion 300 is provided with a matching portion 310 corresponding to a snap-fit portion 120 of the light shielding component 100.

(14) Preferably, the optical structure according to the present invention further comprises a light source 400.

(15) The light source 400 is located at an opening end of the light guide 200, and the light shielding component 100 is located at an end of the light guide 200.

(16) According to the optical structure of the present invention, the supporting portion 300 is used to support the light guide 200 and the light shielding component 100.

(17) Referring to FIGS. 1 and 2, the light shielding component 100 comprises a covering portion 110 and the snap-fit portion 120, wherein the covering portion 110 is used to cover the light guide 200 to block the transmission of light rays, and the snap-fit portion 120 is used to fix the light shielding component 100.

(18) Specifically, the light shielding component 100 is located at the end of the light guide 200, covers the light guide 200 via the covering portion 110, and is connected to the supporting portion 300 via the snap-fit portion 120.

(19) Specifically, the supporting portion 300 comprises an accommodation portion 320 for accommodating the light guide 200. More preferably, a main body 210 of the light guide 200 is in the shape of a long strip, the accommodation portion 320 is an arc-shaped groove, and the covering portion 110 comprises an arc-shaped groove matching the light guide 200 in shape.

(20) The snap-fit portion 120 is used to connect the light shielding component 100 to the supporting portion 300.
