It is contemplated to be within the scope of the application that modifications might be made by persons of ordinary skill in the art, and the examples are intended to cover all such modifications as fall within the scope of the requirements.

[0033] In the description of the utility model, it needs to be explained that, unless there is explicit definition and limitation, the terms "mounting", "setting", "connecting" should be understood broadly, for example, "connecting" can be fixed connection, also can be detachable connection, or integral connection, can be direct connection, also can be indirect connection through intermediate medium, can be the intercommunication of two elements or the interaction of two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to specific circumstances.

[0034] First of all, it needs to be explained that, in order to facilitate understanding, such as Figure 3As shown, based on the optical axis of the lens, the light exit end is "front", the light incident end is "back", the left side along the light exit direction is "left", the right side along the light exit direction is "right", the upper side along the light exit direction is "up", and the lower side along the light exit direction is "down", it should be understood that the terms are based on the orientation or positional relationship shown in the drawings, only for the convenience of describing the utility model and simplifying the description, and not indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the utility model.

[0035] Referring to Figures 1 to 5 As shown, the utility model provides a kind of shading assembly, which is used with light source, primary optical element 6, light emitting element 7 to constitute low beam optical module, wherein light source, primary optical element 6, shading assembly and light emitting element 7 are sequentially arranged along optical path.

[0036] Wherein, shading assembly has light shield 1, light blocking structure 3 is arranged below light shield 1, light blocking structure 3 is provided with light passing port 4, and light passing port 4 is provided with reflection structure 5 correspondingly, part of light emitted by light source is converged after primary optical element 6, then enters light passing port 4 after reflection by reflection structure 5 and is transmitted to light emitting element 7 below light shield 1, and low beam III area light pattern a is formed by light emitting element 7 and projection.

[0037] In the utility model, the role of light blocking structure 3 is to ensure that part of light passing below light shield 1 can be transmitted to light emitting element 7 after passing through light passing port 4 to form low beam III area light pattern a, and to block the rest of light passing below light shield 1 to avoid forming stray light, to ensure that the formed low beam light pattern b meets the regulatory requirements and the light pattern is uniform, the role of light passing port 4 is to receive the light reflected by reflection structure 5 and make the light transmitted below light shield 1 to form low beam III area light pattern a, and the role of reflection structure 5 is to reflect part of light converging through primary optical element 6 and directed below light shield 1, so that the reflected light can enter light passing port 4 to realize the transmission of light forming low beam III area light pattern a.The utility model realizes low beam III area light pattern a by setting light blocking structure 3, light passing port 4 and reflection structure 5 on light shield 1 in cooperation with light source, primary optical element 6 and light emitting element 7, avoids processing the inner and outer surfaces or structures of light emitting element 7 (such as lens), ensures the machining precision of light emitting element 7 and other optical elements, guarantees the optical effect of light emitting element 7, and will not affect the uniformity and maximum brightness of low beam light pattern b.

[0038] It should be noted that the shape of the light passing port 4 can be rectangular, circular, etc., and the shape of the reflecting surface of the reflecting structure 5 can also be rectangular, circular, etc., and the reflecting structure 5 and the light passing port 4 can be arranged at any position on the light blocking structure 3 as long as it can ensure that the part of the light transmitted along the lower side of the light shielding plate 1 can be transmitted through the light passing port 4 and then cooperate with the light emitting element 7 to form the low beam III area light pattern a. The light shielding assembly provided by the utility model can form the low beam III area light pattern a without processing the inner and outer surfaces or structures of the light emitting element 7 (such as a lens), thereby ensuring the optical effect of the light emitting element 7, facilitating processing, and ensuring the uniformity and maximum brightness of the formed low beam light pattern.

[0039] Specifically, as shown in Figure 1 and Figure 5 , as a preferred embodiment of the utility model, the light blocking structure 3 can be a light blocking plate arranged below the rear end of the light shielding plate 1, the light passing port 4 is rectangular in shape and is arranged on the light blocking plate, the reflecting structure 5 can be a rectangular reflecting plate arranged below the light passing port 4, the light is reflected by the reflecting plate and then enters the light passing port 4, and after being transmitted through the light passing port 4, it cooperates with the light emitting element 7 to project and form the low beam III area light pattern a, and the light blocking plate blocks the rest of the light transmitted along the lower side of the light shielding plate 1 to avoid forming stray light, thereby ensuring the uniformity of the low beam light pattern b and meeting the regulatory requirements. At the same time, the low beam III area light pattern a can be formed without processing the inner and outer surfaces or structures of the light emitting element 7 (such as a lens), thereby ensuring the optical effect of the light emitting element 7, facilitating processing, and ensuring the uniformity and maximum brightness of the formed low beam light pattern b.

[0040] Further, as some specific embodiments of the utility model, the front end upper edge of the light shielding plate 1 is formed with a cut-off line structure 2, the light shielding plate 1 has a through slot extending in the front-rear direction towards the primary optical element 6 with the cut-off line structure 2 as a reference, and the light passing port 4 is at least partially arranged below the through slot.

[0041] As can be understood, Figure 1 and Figure 5 , the cut-off line structure 2 can be arranged on the front end upper edge of the light shielding plate 1, the light passing through the cut-off line structure 2 forms a low beam light pattern b with a bright-dark cut-off line after being cut off, the light shielding plate 1 has a through slot extending in the front-rear direction towards the primary optical element 6 with the cut-off line structure 2 as a reference, and the light passing port 4 is at least partially arranged below the through slot. From the perspective of the physical structure, in order to form the cut-off line structure 2, the light shielding plate 1 is bent so that the boundary of the light shielding plate 1 forms a bent cut-off line structure 2, thereby forming a through slot in the front-rear direction, and the light passing port 4 can be arranged corresponding to the through slot.

[0042] It should be noted that, as Figure 1 and Figure 5As shown in the figure, the low beam III area light pattern a is located above the bright-dark cutoff line of the low beam light pattern b, therefore, the light passing opening 4 arranged on the light blocking structure 3 is not strictly limited to be located at the position corresponding to the through slot of the light shielding plate 1, and can be moved in the left-right direction on the light blocking structure 3, and at the same time, the reflection structure 5 is deflected left or right, so that the light can be projected to the position required by the low beam III area light pattern a. Of course, the light passing opening 4 is arranged corresponding to the through slot, and this arrangement is the simplest in terms of process realizability, because the low beam III area light pattern is usually above the bright-dark cutoff line, and the light passing opening 4 is arranged corresponding to the cutoff line structure 2 and the through slot, and the angle requirement of the reflection structure 5 can be reduced.

[0043] As some specific embodiments of the present application, the opening width of the light passing opening 4 in the left-right direction is 5mm-15mm.

[0044] It can be understood that the "left-right direction" in the above embodiment is based on the vehicle, and the "left-right direction" is basically equivalent to the left-right direction of the vehicle, such as Figure 1 and Figure 5 As shown in the figure, the maximum opening width of the light passing opening 4 in the left-right direction is 15mm, and the minimum opening width of the light passing opening 4 in the left-right direction is 5mm, and the light passing through the width range can ensure the brightness and illumination range of the low beam III area light pattern a formed later.

[0045] As some specific embodiments of the present application, an included angle is formed between the longitudinal section line of the reflecting surface of the reflection structure 5 and the optical axis of the light emitting element 7, and the angle range of the included angle is 10°-30°.

[0046] It can be understood that, as shown in Figure 1 and Figure 5 The reflection structure 5 is folded upward, so that the longitudinal section line of the reflecting surface of the reflection structure 5 and the optical axis of the light emitting element 7 form an included angle, and the maximum angle is 30° and the minimum angle is 10°. By controlling the included angle between the longitudinal section line of the reflecting surface of the reflection structure 5 and the optical axis of the light emitting element 7, the light flux of the light passing through the light passing opening 4 is controlled, so as to prevent the low beam III area light pattern a from being too bright due to too much light passing through the light passing opening 4, and at the same time, the light blocking structure 3 blocks the remaining light, avoids forming stray light to affect the low beam light pattern b, ensures the uniformity and maximum brightness of the low beam light pattern b, and the light passing through the light passing opening 4 on the light blocking structure 3 forms the low beam III area light pattern a, without the need to process the light emitting element 7, such as a lens, to form the low beam III area light pattern a, thereby ensuring the optical effect of the light emitting element 7 and facilitating processing.

[0047] As some specific embodiments of the utility model, the reflecting surface of the reflecting structure 5 can be treated with aluminum plating to form an aluminum-plated reflecting layer.

[0048] As some specific embodiments of the utility model, as shown in Figure 1 The light-blocking structure 3, the reflecting structure 5 and the light shield 1 are integrally formed, which simplifies the installation, ensures the structural stability of the light shield 1 and reduces the production cost.

[0049] As some specific embodiments of the utility model, the light shield 1 is deflected upward or downward relative to the optical axis of the light-emitting element 7. Figure 5 As shown in the light shield 1 in the middle, the side close to the light-emitting element 7 is low, the side close to the primary optical element 6 is high, and the downward deflection is the opposite, and the included angle formed by the light shield 1 and the optical axis of the light-emitting element 7 ranges from 0° to 5°, so that the light forming the low beam III area light pattern a can reach the reflecting structure 5 and enter the light passage 4 after being reflected by the reflecting structure 5.

[0050] As some specific embodiments of the utility model, along the front-rear direction, a spacing is formed between the light passage 4 and the light-emitting surface of the primary optical element 6, and the spacing ranges from 7 to 10 mm.

[0051] As shown in Figure 1 The spacing between the light-emitting surface of the primary optical element 6 and the light passage 4 is 7-10 mm, and the light flux of the light entering the light passage 4 is controlled by controlling the distance between the light-emitting surface of the primary optical element 6 and the light passage 4, so as to control the brightness of the low beam III area light pattern a.

[0052] The utility model discloses a second aspect further provides a kind of low beam optical module, including light source, primary optical element 6, light-emitting element 7 and the light shield subassembly of above-mentioned scheme.

[0054] The embodiment can realize the design of "white space" of the low beam III area light pattern a, as shown in Figure 5As shown, the embodiment can control the light projection angle of the low beam III area light pattern a by adjusting the position of the reflection structure 5 and the light transmission port 4, and further control the height of the low beam III area light pattern a relative to the low beam light pattern b, so as to avoid the high energy above the bright-dark cutoff line of the low beam light pattern b causing glare, and at the same time meet the regulatory requirements. When designing the low beam III area light pattern a, the bright-dark cutoff line of the low beam light pattern b and the low beam III area light pattern a are often left with a "blank" area to meet the regulatory requirements of the low beam III area. The so-called "blank" area is that the energy in the -0.57° to +1° area of the "bath" of the bright-dark cutoff line of the low beam light pattern b is as weak as possible, for example, Figure 1 As shown, the lower edge of the blank area c is the upper edge of the bright-dark cutoff line.
