[0036] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0037] Reference Figures 1 to 3 According to an embodiment of the utility model, a vehicle lamp assembly is proposed, including a light distribution mirror 100 and a light guide structure 200. The light guide structure 200 is arranged on the rear side of the light distribution mirror 100. The light guide structure 200 includes a main body 210 and an extension section 230. A bending portion 220 is provided between the main body 210 and the extension section 230. The bending portion 220 connects the main body 210 and the extension section 230 respectively. The extension section 230 is inclined along the front-to-back direction. The projection of the bending portion 220 in the front-to-back direction and the projection of the main body 210 in the front-to-back direction have an angle a, and satisfy: 55°≤a≤65°.

[0038] Specifically, the vehicle lamp assembly provided by the embodiment of the utility model sets a bending portion between the main body 210 and the extension section 230, so that the extension section 230 can be tilted in the front-to-back direction, and the projection of the bending portion 220 in the front-to-back direction forms an angle with the projection of the main body 210 in the front-to-back direction, so that the extension section 230 can be hidden on the upper side or lower side of the light distribution mirror 100, thereby reducing the possibility of the user looking directly at the bright spot at the end of the light guide strip, and making the visible area of ​​the light guide strip (that is, the part of the main body 210 exposed on the rear side of the light distribution mirror 100 and able to be directly viewed by the user) emit light evenly, thereby optimizing the lighting effect of the vehicle lamp, and being suitable for vehicles.

[0039] It is understandable that the inventors learned during the experiment that if the inclination angle of the extension section 230 along the front-to-back direction is too small, that is, the angle between the projection of the bending portion 220 in the front-to-back direction and the projection of the main body 210 in the front-to-back direction is too small, the extension section 230 cannot be well hidden in the upper side or lower side of the light distribution mirror 100, which increases the possibility of the bright spot at the end of the extension section 230 being directly viewed by the user, and the lighting effect is uneven; if the inclination angle of the extension section 230 along the front-to-back direction is too large, that is, the angle between the projection of the bending portion 220 in the front-to-back direction and the projection of the main body 210 in the front-to-back direction is too large, there is a possibility that the light emitted by the bright spot at the end of the extension section 230 is blocked by the main body 210 in the height direction, which easily makes the light of the bright spot unable to fully diffuse, resulting in a dark area at the end of the light distribution mirror 100, affecting the lighting effect. To this end, in the embodiment of the utility model, the included angle between the projection of the bending portion 220 in the front-to-back direction and the projection of the main body 210 in the front-to-back direction is a, and satisfies: 55°≤a≤65°, so that the extension section 230 can be well hidden in the upper or lower side of the light distribution lens 100, thereby reducing the possibility of the user looking directly at the bright spot at the end of the light guide strip, making the visible area of ​​the light guide strip illuminate evenly, and reducing the possibility of the light emitted by the bright spot at the end of the extension section 230 being blocked by the main body 210 in the height direction, so that the light of the bright spot can be fully diffused, thereby reducing the possibility of a dark area appearing at the end of the light distribution lens 100, and optimizing the lighting effect of the car light.

[0040] Specifically, refer to Figure 2 In the embodiment of the utility model, the main body 210 and the extension section 230 are both cylinders, the axis of the main body 210 is the first axis 310, the axis of the extension section 230 is the second axis 320, and the first axis 310 and the second axis 320 intersect in the front-to-back direction to form a projection angle a.

[0041] Reference Figure 1 and Figure 5According to some embodiments of the present invention, a light guide rack 250 is provided on the side surface of the main body 210 facing away from the light distribution lens 100. The light guide rack 250 extends along the axial direction of the main body 210. The light guide rack 250 is used to reflect the light transmitted from the inside of the main body 210 to the light distribution lens 100 to achieve the lighting function.

[0042] Reference Figure 2 and Figure 3 According to some embodiments of the present invention, the bending portion 220 is extended away from the light distribution mirror 100, and the extension section 230 is tilted downward or upward in a direction away from the light distribution mirror 100. It can be understood that if the extension section 230 is tilted only in the front-to-back direction, part of the light emitted by the bright spot at its end may be blocked by the main body 210 in the height direction, which may cause the light of the bright spot to be unable to fully diffuse, resulting in a dark area at the end of the light distribution mirror 100. To this end, the embodiment of the present invention extends the bending portion 220 away from the light distribution mirror 100, that is, the extension section 230 is tilted away from the light distribution mirror 100 toward the oblique rear, so that the light of the bright spot can be fully diffused, thereby lighting up the dark area at the end of the light distribution mirror 100, improving the lighting effect, and enhancing the user experience.

[0043] It is understandable that the inventors learned during the experiment that if the angle between the projection of the bending portion 220 in the height direction and the projection of the main body 210 in the height direction is too small, the possibility of the light emitted by the bright spot at the end of the extension section 230 being blocked by the main body 210 in the height direction will increase, making it impossible for the light of the bright spot to fully diffuse, resulting in a dark area at the end of the light distribution lens 100; and if the angle between the projection of the bending portion 220 in the height direction and the projection of the main body 210 in the height direction is too large, it is easy to cause the extension section 230 to be unable to be well hidden in the upper or lower side of the light distribution lens 100, increasing the possibility of the bright spot at the end of the extension section 230 being directly viewed by the user and resulting in uneven lighting effect. For this reason, refer to Figure 3 In the embodiment of the utility model, the included angle between the projection of the bending portion 220 in the height direction and the projection of the main body 210 in the height direction is b, and satisfies: 5°≤b≤15°, so that the extension section 230 can be well hidden in the upper side or lower side of the light distribution mirror 100, thereby reducing the possibility of the user looking directly at the bright spot at the end of the light guide strip, making the visible area of ​​the light guide strip illuminate evenly, and reducing the possibility of the light emitted by the bright spot at the end of the extension section 230 being blocked by the main body 210 in the height direction, so that the light of the bright spot can be fully diffused, thereby reducing the possibility of a dark area appearing at the end of the light distribution mirror 100, and optimizing the lighting effect of the car lamp.

[0044] Specifically, refer to Figure 2In the embodiment of the utility model, the main body 210 and the extension section 230 are both cylinders, the axis of the main body 210 is the first axis 310, the axis of the extension section 230 is the second axis 320, and the first axis 310 and the second axis 320 intersect in the height direction to form a projection angle b.

[0045] Preferably, according to some embodiments of the present invention, the included angle between the projection of the bending portion 220 in the height direction and the projection of the main body 210 in the height direction satisfies: b=7°, so that the bright spot at the end of the extension section 230 is hidden while the dark area at the end of the lens 100 can be fully illuminated to obtain the best lighting effect.

[0046] Preferably, according to some embodiments of the present invention, the angle between the projection of the bending portion 220 in the front-to-back direction and the projection of the main body 210 in the front-to-back direction satisfies: a=63°, so that the bright spot at the end of the extension section 230 is hidden while the dark area at the end of the lens 100 can be fully illuminated to obtain the best lighting effect.

[0047] Reference Figure 2 According to some embodiments of the present invention, the end surface of the end of the extension section 230 is an arc surface, and the bending portion 220 and the side surface of the extension section 230 close to the light distribution lens 100, as well as the arc surface are provided with a leather grain structure or an optical stripe structure. Specifically, the leather grain structure or the optical stripe structure can disperse and modulate the light, so that the light is further diffused, which can effectively dilute the bright spot and make the light emission more uniform, thereby improving the light emission effect.

[0048] For example, in some embodiments, an optical stripe structure may be provided on a surface of one side of the extension section 230 close to the lens 100. The optical stripe structure may be a plurality of vertical stripes extending along the axial direction of the extension section 230. The plurality of vertical stripes are evenly spaced around the circumference of the extension section 230, thereby breaking up and modulating the light emitted from the extension section 230 toward the lens 100, so that the light is further diffused, thereby making the light emission more uniform.

[0049] Reference Figure 1 and Figure 4According to some embodiments of the utility model, the vehicle lamp assembly further includes a mounting portion 240 for fixing the main body 210, and the mounting portion 240 is connected to the outer peripheral wall of the main body 210. Preferably, in the embodiment of the utility model, there are two mounting portions 240, and the two mounting portions 240 are respectively connected to the two ends of the main body 210. In one example, the mounting portion 240 is integrally formed with the main body, and the mounting portion 240 is provided with a mounting hole, and the light guide structure 200 is installed by fasteners and the mounting hole. In another example, the mounting portion 240 can also be a metal bracket or an angle code, and can be connected to the main body 210 by welding, or can be connected to the main body 210 by bolts and other fixings, which can be determined according to actual conditions and will not be elaborated here.

[0050] According to some embodiments of the utility model, the main body 210, the bending portion 220 and the extension section 230 are integrally formed. Preferably, the light guide strip is a resin part, and the material used may be acrylic resin, polycarbonate, epoxy resin, etc. The molding method used may be injection molding, thereby reducing production costs.

[0051] A vehicle lamp proposed according to the utility model includes a thick-walled part and a vehicle lamp assembly of any one of the above-mentioned embodiments. The thick-walled part is arranged between the light distribution lens 100 and the light guide structure 200. The thick-walled part is used to transmit light and can enhance and homogenize the light. Since the vehicle lamp adopts all the above-mentioned technical solutions, it should have the same beneficial effects and will not be described in detail here.

[0052] A vehicle proposed in the present invention includes the headlights of the above embodiment. Since the vehicle adopts all the above technical solutions, it should have the same beneficial effects, which will not be described in detail here.
