[0032] Please refer to Figure 1 and Figure 2The present embodiment provides a shading plate structure 110, which is used in a vehicle lamp module 100. The vehicle lamp module 100 includes a light source 120 and a lens 130. The shading plate structure 110 is arranged between the light source 120 and the lens 130. The shading plate structure 110 includes a first shading portion 111 and a second shading portion 112 adjacent to each other. A first dimming surface 1111 of the first shading portion 111 and a second dimming surface 1121 of the second shading portion 112 are located on the same side of the shading plate structure 110. The first dimming surface 1111 and the second dimming surface 1121 are connected and form a preset angle. The light emitted by the light source 120 passes through the shading plate structure 110 and is projected by the lens 130 to form an illumination light pattern, wherein the light irradiated to the first dimming surface 1111 is reflected by the first dimming surface 1111 and emitted at a first angle, and the light irradiated to the second dimming surface 1121 is reflected by the second dimming surface 1121 and emitted at a second angle.

[0033] Specifically, when using the shading plate structure 110 of the present application, the shading plate structure 110 is placed between the light source 120 and the lens 130 in the car lamp module 100. The shading plate structure 110 has a first dimming surface 1111 and a second dimming surface 1121 set at a preset angle. The light emitted by the light source 120 is partially projected onto the first dimming surface 1111 and the second dimming surface 1121 of the shading plate structure 110. The light projected onto the first dimming surface 1111 is reflected by the first dimming surface 1111 to the lens 130, and the light projected onto the second dimming surface 1121 is reflected by the second dimming surface 1121 to the lens 130. Since the first dimming surface 1111 and the second dimming surface 1121 have different reflection angles for the light, the light projected thereon can be reflected in different directions and projected to different areas of the light pattern through the lens 130, thereby adjusting the light pattern and improving the lighting effect of the car lamp.

[0034] It should be noted that the lighting light pattern includes an upper half and a lower half. The light beam reflected by the first dimming surface 1111 can be projected onto the upper half of the lighting light pattern, and the light beam reflected by the second dimming surface 1121 can be projected onto the lower half of the lighting light pattern, so that the light beam projected onto the shading plate can be reflected onto the upper and lower halves of the lighting light pattern to achieve the effect of adjusting the entire lighting light pattern. At the same time, both the first dimming surface 1111 and the second dimming surface 1121 are reflective surfaces, which can enable more light to be projected into the lighting light pattern, thereby improving the brightness of the lighting light pattern.

[0035] The shading plate structure 110 provided in the present application is used in a vehicle lamp module. The shading plate structure 110 is arranged between the light source 120 and the lens 130. The shading plate structure 110 includes a first shading portion 111 and a second shading portion 112 adjacent to each other. A first dimming surface 1111 of the first shading portion 111 and a second dimming surface 1121 of the second shading portion 112 are located on the same side of the shading plate structure 110. The first dimming surface 1111 and the second dimming surface 1121 are connected and form a preset angle. The light emitted by the light source 120 irradiates the The light from the first dimming surface 1111 is reflected by the first dimming surface 1111 and emitted to the lens 130 at a first angle, and the light irradiated to the second dimming surface 1121 is reflected by the second dimming surface 1121 and emitted to the lens 130 at a second angle. The first dimming surface 1111 and the second dimming surface 1121 have different reflection angles for the light, so the light projected thereon can be reflected in different directions and projected to different areas of the lighting light type through the lens 130, thereby adjusting the lighting light type and improving the lighting effect of the car lamp.

[0036] In a possible embodiment of the present application, Figure 1 , Figure 2 and Figure 5 As shown, the first dimming surface 1111 and the second dimming surface 1121 intersect at the junction to form a first axis 113, the optical axis of the lens 130 is perpendicular to the first axis 113, the first axis 113 is located on the reference plane, the reference plane is parallel to the optical axis, the first dimming surface 1111 and the second dimming surface 1121 are respectively located on both sides of the reference plane, that is, relative to the reference plane, the first dimming surface 1111 is bent downward around the first axis 113, and the second dimming surface 1121 is bent upward around the first axis 113, among the light emitted by the light source 120, the light irradiated to the first dimming surface 1111 is reflected by the first dimming surface 1111 and emitted to the lens 130 at a first angle, and the light irradiated to the second dimming surface 1121 is reflected by the second dimming surface 1121 and the upper boundary of the light output light type obtained by the lens 130 can be more closely aligned with the cutoff line, thereby improving the illumination value at the cutoff line of the lighting light type.

[0037] It should be noted that the angle between the first dimming surface and the reference surface is less than 20°, and the angle between the second dimming surface and the reference surface is less than 20°. For example, the angle between the first dimming surface and the reference surface may be 10°, 12°, 15° or 18°, and the angle between the second dimming surface and the reference surface may be 10°, 12°, 15° or 18°.

[0038] In a feasible embodiment of the present application, Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, along the first axis 113 , the first dimming surface 1111 includes a first dimming zone 1111 a , a second dimming zone 1111 b , and a third dimming zone 1111 c which are connected in sequence.

[0039] The first dimming zone 1111a and the third dimming zone 1111c correspond to the widened area of ​​the illumination light type, and the second dimming zone 1111b corresponds to the central brightness area of ​​the illumination light type. The widened area of ​​the illumination light type is correspondingly adjusted by the first dimming zone 1111a and the third dimming zone 1111c, and the central brightness area of ​​the illumination light type is correspondingly adjusted by the second dimming zone 1111b, so that the upper boundary of the light output light type obtained after reflection by the bent first dimming surface 1111 and projection by the lens 130 can better fit the cutoff line of the illumination light type, thereby improving the adjustment accuracy of the shading plate structure 110 for the illumination light type including the cutoff line area.

[0040] In a feasible embodiment of the present application, Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the first dimming zone 1111a and the third dimming zone 1111c have different bending angles relative to the first axis 113, and the angle between the first dimming zone 1111a and the reference plane is greater than the angle between the third dimming zone 1111c and the reference plane.

[0041] Specifically, the first dimming surface 1111 is set to be a first dimming zone 1111a, a second dimming zone 1111b and a third dimming zone 1111c which are arranged in sequence, the first dimming zone 1111a is bent downward by 0°-5° around the first axis 113, and the third dimming zone 1111c is bent upward by 0°-5° around the first axis 113, so that the angle between the first dimming zone 1111a and the third dimming zone 1111c is 0°-10°, so that the upper boundary of the light output light type after dimming processing by the first dimming zone 1111a, the second dimming zone 1111b and the third dimming zone 1111c can be more closely fitted to the cutoff line of the lighting light type.

[0042] Furthermore, the second dimming zone 1111b may be a curved surface connecting the first dimming zone 1111a and the third dimming zone 1111c, so as to further ensure that the upper boundary of the light emitting pattern can better fit the cutoff line of the illumination light pattern.

[0043] For example, the first dimming zone 1111 a may be bent 2° downward around the first axis 113 , and the third dimming zone 1111 c may be bent 3° upward around the first axis 113 .

[0044] For example, the first dimming zone 1111 a may be bent 3° downward around the first axis 113 , and the third dimming zone 1111 c may be bent 4° upward around the first axis 113 .

[0045] In a feasible embodiment of the present application, Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the first dimming zone 1111a, the second dimming zone 1111b, and the third dimming zone 1111c connected in sequence form a cut-off line structure near the edge of the lens 130, which is used to form a cut-off line of the illumination light pattern. The sequential connection of the first dimming zone 1111a, the second dimming zone 1111b, and the third dimming zone 1111c also makes the cut-off line shape meet regulatory requirements.

[0046] Specifically, a cutoff line structure is formed at the edge of the first dimming zone 1111a, the second dimming zone 1111b, and the third dimming zone 1111c near the lens 130, so that the lighting light type after dimming by the first dimming zone 1111a, the second dimming zone 1111b, and the third dimming zone 1111c has a cutoff line and the shape of the cutoff line meets regulatory requirements.

[0047] It should be noted that the shape of the second dimming area 1111b near the edge of the lens 130 is not limited and can be Figure 3 and Figure 4 The inclined straight line or curve shown in the figure makes the formed cutoff line structure present a "Z" shape, and the second dimming zone 1111b can also be recessed in the first dimming zone 1111a and the third dimming zone 1111c in the up and down directions, so that the second dimming zone 1111b is close to the boundary of the lens 130 and combines with the boundary of the first and third dimming zones to form a "bathtub" shaped cutoff line structure. The specific shape of the cutoff line structure needs to be set according to different regulatory requirements.

[0048] In a feasible embodiment of the present application, Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, along the first axis 113, the second dimming surface 1121 includes a fourth dimming zone 1121a, a fifth dimming zone 1121b, and a sixth dimming zone 1121c connected in sequence, and the fourth dimming zone 1121a, the fifth dimming zone 1121b, and the sixth dimming zone 1121c form a preset angle. The fourth dimming zone 1121a and the sixth dimming zone 1121c correspond to the widening area of ​​the lighting light type, and the fifth dimming zone 1121b corresponds to the central brightness area of ​​the lighting light type, so as to achieve precise adjustment of the second dimming surface 1121, and the light output light type obtained by the reflection of the second dimming surface 1121 and the projection of the lens 130 can improve the illumination value of the lower half of the lighting light type.

[0049] In a feasible embodiment of the present application, Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the included angles between the fourth dimming zone 1121a and the sixth dimming zone 1121c and the reference plane are the same, and the included angle between the fourth dimming zone 1121a and the reference plane is greater than the included angle between the fifth dimming zone 1121b and the reference plane.

[0050] Specifically, the fourth dimming zone 1121a and the sixth dimming zone 1121c are bent upward by 0°-5° around the first axis 113, so that the included angle between the fourth dimming zone 1121a and the fifth dimming zone 1121b is 0°-5°, and the included angle between the sixth dimming zone 1121c and the fifth dimming zone 1121b is 0°-5°, so as to achieve the upward contraction of both sides of the lighting light pattern and compensate for the problem of the lighting light pattern falling off on both sides caused by the distortion of the lens 130.

[0051] Furthermore, the fourth dimming zone 1121a and the fifth dimming zone 1121b are connected via a first connecting surface, and the fifth dimming zone 1121b and the sixth dimming zone 1121c are connected via a second connecting surface, and the first connecting surface and the second connecting surface are curved surfaces or flat surfaces.

[0052] It should be noted that the above six dimming area divisions are only examples. The first dimming surface 1111 and the second dimming surface 1121 of the shading plate structure 110 can also be divided into different dimming areas according to needs, and corresponding light type adjustments can be made through different dimming areas to achieve more precise light type adjustment.

[0053] In a feasible embodiment of the present application, Figure 1 and Figure 2 As shown, the sunshade structure 110 also includes a first connection portion 115 and a second connection portion 116. The first connection portion 115 and the second connection portion 116 are relatively arranged on both sides of the sunshade structure 110. The sunshade structure 110 is installed in the vehicle lamp module through the first connection portion 115 and the second connection portion 116.

[0054] Specifically, when the sunshade structure 110 is fixed in the headlight module, connecting holes are provided on the first connecting part 115 and the second connecting part 116, and corresponding mounting holes can be provided on the lens bracket of the headlight module. The fixing parts pass through the connecting holes on the first connecting part 115 and the second connecting part 116 and the mounting holes on the lens bracket, thereby realizing the installation of the sunshade structure 110 in the headlight module.
