[0029] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0030] Reference is made below to the accompanying drawings that show by way of example Figures 1-3 a lampshade 100 according to an embodiment of the present application.

[0031] With reference to Figure 1 , Figure 2 and Figure 3 , the lampshade 100 according to the first aspect embodiment of the present application, the lampshade 100 comprises a lampshade body 10, and the outer surface of the lampshade body 10 is provided with a plurality of first light-guiding convex parts 11 which are outwardly convex and arranged in sequence, that is, the outer surface of the lampshade body 10 can be provided with two, three or four or more first light-guiding convex parts 11, and the side surface of the first light-guiding convex part 11 away from the lampshade body 10 (such as the front side surface of the lampshade body 10 shown in Figure 2 ) is an outwardly convex arc surface.

[0032] For example, as shown in Figure 1 , Figure 2 and Figure 3 , the outer surface of the lampshade body 10 is provided with four first light-guiding convex parts 11 which are outwardly convex and arranged in sequence, and the front side surface of the first light-guiding convex part 11 is an outwardly convex arc surface.

[0033] The lamp cover 100 of this utility model has multiple first light-guiding protrusions 11 on the lamp cover body 10. Light can be directly emitted from the first light-guiding protrusions 11 to the external space without the need for additional light-guiding structures. This reduces the number of parts used, lowers the production cost of the vehicle lamp assembly 1000, and also reduces the assembly steps of the lamp cover 100, improving the assembly efficiency. At the same time, the multiple first light-guiding protrusions 11 can guide the light emitted by the light source to different positions, thereby optimizing the illumination distribution of the vehicle. Therefore, it can ensure the illumination intensity and uniformity of the light emitted by the lamp cover 100, ensuring that the vehicle has good lighting function, thereby improving driving safety and enhancing the market competitiveness of the product.

[0034] In addition, the integrated design of the lamp cover body 10 and the first light guide protrusion 11 can reduce the overall volume of the lamp cover 100, thereby reducing the installation space required for the lamp cover 100, which in turn facilitates the installation of the lamp cover 100 on the vehicle. Furthermore, it can reduce the number of seams when the parts are fitted together, thereby effectively improving the waterproof and dustproof performance, and thus ensuring the service life of the vehicle lamp assembly 1000.

[0035] According to the embodiment of the present utility model, the lamp cover 100 has a plurality of first light guiding protrusions 11 on the lamp cover body 10, which can reduce the number of parts used and reduce the production cost of the vehicle lamp assembly 1000. At the same time, it can optimize the light distribution of the vehicle, thereby ensuring the illumination intensity and uniformity of the light emitted by the lamp cover 100, and thus improving driving safety.

[0036] According to some embodiments of this utility model, refer to Figure 1 and Figure 2 The first light guide protrusion 11 extends from the length direction of the lampshade body 10 (e.g., Figure 1 One end of the left and right directions shown (as shown) Figure 1 The lampshade body 10 shown extends from the left end to the other end (as shown). Figure 1 (As shown, at the right end of the lampshade body 10), a plurality of first light-guiding protrusions 11 are located in the width direction of the lampshade body 10 (e.g., at the right end of the lampshade body 10). Figure 1 Arranged at intervals in the vertical direction as shown.

[0037] In this way, by limiting the extension direction of the first light guide protrusion 11, the light can be propagated and diffused along a certain path, making the light distribution in the entire illumination area more uniform and avoiding areas that are too bright or too dark. At the same time, the reasonable arrangement of multiple first light guide protrusions 11 and the light from different first light guide protrusions 11 into the external space can ensure the brightness of the light of the vehicle headlight assembly 1000.

[0038] For example, such as Figure 1 and Figure 2As shown, the first light guide protrusions 11 extend from the left end to the right end of the lampshade body 10, and the four first light guide protrusions 11 are arranged in the up-down direction.

[0039] According to some embodiments of the present application, referring to Figure 1 and Figure 2 , the distance between the two adjacent first light guide protrusions 11 is 1.5cm-2.5cm. Therefore, the reasonable setting of the distance between the first light guide protrusions 11 can ensure the uniform distribution of light in the entire lighting area, and avoid the local over-bright or over-dark phenomenon caused by too dense or sparse.

[0040] For example, as shown in Figure 1 and Figure 2 , the distance between the two adjacent first light guide protrusions 11 can be 1.5cm, 1.6cm, 1.7cm, 1.8cm, 1.9cm, 2cm, 2.1cm, 2.2cm, 2.3cm, 2.4cm or 2.5cm.

[0041] According to some embodiments of the present application, referring to Figure 1 and Figure 2 , the height of the first light guide protrusion 11 protruding from the outer surface of the lampshade body 10 is 1cm-1.5cm. Therefore, by limiting the protruding height of the first light guide protrusion 11, the first light guide protrusion 11 can not only reasonably adjust the light emitting angle of the light, but also avoid the increase of the volume of the lampshade 100 caused by the too high protruding height of the first light guide protrusion 11.

[0042] For example, as shown in Figure 1 and Figure 2 , the height of the first light guide protrusion 11 protruding from the outer surface of the lampshade body 10 can be 1cm, 1.1cm, 1.2cm, 1.3cm, 1.4cm or 1.5cm.

[0043] According to some embodiments of the present application, referring to Figure 1 and Figure 2 , in the width direction of the lampshade body 10 (such as the up-down direction as shown in Figure 1 ), the lampshade body 10 is an arc-shaped plate body protruding towards the side where the first light guide protrusion 11 is located (such as the upper side of the lampshade body 10 as shown in Figure 1 ). Therefore, the arc-shaped lampshade body 10 can better diffuse the light, so that the light is uniformly distributed within a certain range, improving the lighting effect. At the same time, the lampshade body 10 can be integrated with the body curve, making the entire vehicle body look more smooth and modern, increasing the visual appeal of the vehicle.

[0044] According to some embodiments of the present application, referring to Figure 1 and Figure 2The inner surface of the lampshade body 10 is provided with a plurality of second light guide protrusions 12 which are arranged in sequence and protrude inwardly, the side surface of the second light guide protrusion 12 which is away from the lampshade body 10 (for example, the rear side surface of the lampshade body 10 shown in Figure 2 ) is an arc surface which protrudes inwardly, the plurality of second light guide protrusions 12 extend along the length direction of the lampshade body 10 (for example, the left-right direction of the lampshade body 10 shown in Figure 2 ) and are arranged in sequence in the width direction of the lampshade body 10, the plurality of second light guide protrusions 12 correspond to the plurality of first light guide protrusions 11 one by one and are opposite to each other.

[0045] In this way, the second light guide protrusion 12 can cooperate with the first light guide protrusion 11, so that the light can be better dispersed and guided, the light can cover a wider area, the lighting effect can be improved, and meanwhile, the light intensity of the vehicle lamp assembly 1000 in a dark environment or in rainy and foggy weather can be enhanced, so that the safety performance of the vehicle can be improved.

[0046] For example, as shown in Figure 1 and Figure 2 , the rear side surface of the lampshade body 10 is provided with four second light guide protrusions 12 which protrude rearward, the four second light guide protrusions 12 extend along the left-right direction and are arranged in sequence in the up-down direction, the rear side surface of the second light guide protrusion 12 is an arc surface which protrudes rearward, and each second light guide protrusion 12 corresponds to the first light guide protrusion 11 one by one and corresponds to the first light guide protrusion 11 in the front-rear direction.

[0047] According to some embodiments of the present application, with reference to Figure 1 and Figure 2 , the width of the lampshade 100 gradually increases in the direction from one end (for example, the left end of the lampshade 100 shown in Figure 1 ) to the other end (for example, the right end of the lampshade 100 shown in Figure 1 ) of the lampshade 100 in the length direction (for example, the left-right direction of the lampshade 100 shown in Figure 1 ). Thus, it can be ensured that the lampshade 100 can be adapted to the lamp slot on the vehicle, so that the lampshade 100 can be normally installed on the vehicle.
