[0041] 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.

[0042] In the related art, the light guide is usually installed and fixed by means of a mounting member arranged thereon. However, the light inside the light guide is easy to enter the mounting member, and the mounting member often changes the propagation path of the light inside the light guide. When the light guide is illuminated, bright spots and dark areas are easy to appear on the surface of the light guide, causing uneven light emission of the light guide and affecting the light emission effect of the light guide.

[0043] To this end, some embodiments of the present invention provide a light guide 1000, specifically referring to the accompanying drawings of the specification. Figure 1-Figure 8 shown.

[0044] It is understood that the light guide 1000 may be a component of a lighting module in a vehicle lamp and may be used to implement the lighting function of the vehicle lamp. Figure 1 As shown, in an embodiment of the utility model, the light guide 1000 may include: a main body 100 and a first mounting member 200, wherein the main body 100 is capable of transmitting light, specifically, light from a light source can be reflected inside the main body 100 and then emitted toward the front end to achieve a lighting function.

[0045] Reference Figure 2 , Figure 3 and Figure 5 As shown, in the embodiment of the utility model, the first mounting member 200 may include a connecting portion 210, an extending portion 220 and a mounting portion 230, wherein the connecting portion 210 may be connected to one end of the main body 100 in the height direction, that is, the connecting portion 210 may be connected to the top or bottom end of the main body 100. The connecting portion 210 is extended in the height direction, specifically, the connecting portion 210 may be extended from the top or bottom end of the main body 100 in a direction away from the main body 100. It can be understood that since the connecting portion 210 is connected to the top or bottom end of the main body 100 and is extended in the height direction, the angle between the connecting portion 210 and the horizontal section of the main body 100 is a right angle, based on which it is difficult for the light inside the main body 100 to enter the connecting portion 210. In this embodiment, the thickness of the connecting portion 210 in the front-to-back direction may be a, and satisfies: a<2.6mm.

[0046] Reference Figure 2 and Figure 3As shown, in the embodiment of the utility model, the extension part 220 can be extended in the front-back direction, one end of which can be connected to the connecting part 210, and the other end can be connected to the mounting part 230, and the extension part 220 and the mounting part 230 can be located on one side of the main body 100 along the height direction. It can be understood that when the connecting part 210 is connected to the top of the main body 100, the extension part 220 and the mounting part 230 are located on the upper side of the main body 100; when the connecting part 210 is connected to the bottom of the main body 100, the extension part 220 and the mounting part 230 are located on the lower side of the main body 100. Based on this, the projection of the main body 100 in the horizontal direction does not intersect with the projection of the extension part 220 and the mounting part 230 in the horizontal direction. Therefore, when the light guide 1000 is in a non-luminous state, it is difficult for the user to observe the extension part 220 and the mounting part 230 through the main body 100. It should be noted that the mounting portion 230 is used to mount the main body 100. Specifically, the mounting position of the mounting portion 230 and the light guide 1000 can be a snap connection, a screw connection, or other forms of fixed connection. Technicians in this field can choose the setting according to actual conditions, and this embodiment does not limit this.

[0047] In the embodiment of the utility model, the main body 100 and the first mounting member 200 can be integrally formed. Specifically, the light guide 1000 can be made of polymethyl methacrylate or polycarbonate injection molding, which not only improves the strength and integrity of the light guide 1000, but also improves the processing efficiency of the light guide 1000.

[0048] The embodiment of the utility model is provided with a first mounting member 200, wherein the first mounting member 200 includes a connecting portion 210, an extending portion 220 and a mounting portion 230. By connecting the connecting portion 210 to one end of the main body 100 in the height direction and extending the connecting portion 210 in the height direction, it is difficult for the light inside the main body 100 to enter the first mounting member 200 after being reflected by the inner wall thereof, thereby reducing the possibility that the first mounting member 200 changes the propagation path of the light inside the light guide 1000, and making the surface of the light guide 1000 appear bright when illuminated. The possibility of spots and dark areas is greatly reduced, thereby improving the luminous effect of the light guide 1000; at the same time, one end of the extension part 220 is connected to the connecting part 210, and the other end is connected to the mounting part 230, and the installation and fixation of the main body 100 is realized through the mounting part 230; and by arranging the extension part 220 and the mounting part 230 on one side of the main body 100 along the height direction, it is reduced that when the light guide 1000 is in a non-luminous state, the user is less likely to observe the extension part 220 and the mounting part 230 through the main body 100, thereby improving the aesthetics of the light guide 1000.

[0049] Reference Figure 2 , Figure 5 and Figure 7As shown, in the embodiment of the utility model, the mounting portion 230 may be provided with a first mounting hole 231, and the first mounting hole 231 may cooperate with a threaded mating member to achieve a fixed connection with the mounting position of the light guide 1000. In order to facilitate the first mounting hole 231 to align with the mounting position of the light guide 1000, the first mounting member 200 may further include a plurality of positioning portions 240 extending in a direction away from the mounting portion 230. In the embodiment, the positioning portions 240 may be extended backward. The plurality of positioning portions 240 may be arranged at intervals around the circumference of the first mounting hole 231 and connected to the mounting portion 230, and the positioning portions 240 may be integrally formed with the mounting portion 230. It is understandable that when the first mounting hole 231 is aligned with the mounting position of the light guide 1000, the plurality of positioning portions 240 may play a role in positioning and guiding, thereby improving the efficiency and accuracy of the assembly of the light guide 1000.

[0050] It is understandable that in order to balance the stresses borne by various parts of the main body 100, Figure 1 and Figure 2 As shown, in the embodiment of the utility model, two first mounting members 200 may be provided, and the two first mounting members 200 may be spaced apart along the axial direction of the main body 100. It is understandable that when the light guide 1000 is assembled, the two first mounting members 200 may be subjected to force respectively, so that the force on the first mounting member 200 is balanced, reducing the possibility of deformation or fracture of the first mounting member 200 due to stress concentration.

[0051] Reference Figure 2 , Figure 4 and Figure 6As shown, in the embodiment of the utility model, two ends of the main body 100 are respectively provided with a bent and extended bending portion 300. Specifically, the two bending portions 300 can be bent toward each other, thereby shortening the lateral dimension of the light guide 1000 and reducing the space required for assembling the light guide 1000. In order to install and fix the bending portion 300, in the embodiment, the light guide 1000 can also include a second mounting member 400 for mounting the bending portion 300. Specifically, the second mounting member 400 can be connected to one end of the main body 100 in the height direction, and the second mounting member 400 is extended in the height direction. It can be understood that the second mounting member 400 can be connected to the top or bottom end of the bending portion 300, and the second mounting member 400 can be extended from the top or bottom end of the bending portion 300 in a direction away from the bending portion 300. It is understandable that, since the second mounting member 400 is connected to the top or bottom of the bending portion 300 and is extended in the height direction, the angle between the second mounting member 400 and the horizontal section of the bending portion 300 is a right angle, based on which, it is difficult for the light inside the bending portion 300 to enter the second mounting member 400. It should be noted that the mounting position of the second mounting member 400 and the light guide 1000 can be a snap connection, a screw connection, or other forms of fixed connection. Those skilled in the art can select the setting according to actual conditions, and this embodiment does not limit this.

[0052] Reference Figure 2 and Figure 8 As shown, in the embodiment of the utility model, the second mounting portion 230 may be provided with a positioning groove 410, and the positioning groove 410 may be extended forward along the front-back direction, and its opening may be toward the rear side. The bottom wall of the positioning groove 410 may be provided with a second mounting hole 420, and it is understood that the second mounting hole 420 may be matched with a threaded mating piece to achieve a fixed connection with the mounting position of the light guide 1000. When the second mounting hole 420 is aligned with the mounting position of the light guide 1000, the positioning groove 410 may play a role in positioning and guiding, thereby improving the efficiency and accuracy of the assembly of the light guide 1000.

[0053] Reference Figure 2 , Figure 3 and Figure 5 As shown, in an embodiment of the utility model, a reinforcing rib 250 may be provided between the mounting portion 230 and the extension portion 220. Specifically, one end of the reinforcing rib 250 is connected to the extension portion 220, and the other end is connected to the mounting portion 230, thereby improving the structural strength of the first mounting member 200 and further improving the structural stability of the light guide 1000.

[0054] An embodiment of the present utility model further provides a vehicle lamp, comprising a light source and the light guide 1000 of the above embodiment.

[0055] It should be noted that the light source can be an LED lamp bead, a halogen lamp, or other types of light-emitting devices. Those skilled in the art can choose the setting according to actual conditions, and this embodiment does not limit this.

[0056] The headlight of the embodiment of the utility model adopts the light guide 1000 of the above-mentioned embodiment, and the headlight is provided with a light mixing part for mixing light, so that it is connected to one end of the main body 100 in the axial direction, and then a light incident surface is provided at the end of the light mixing part away from the main body 100, and a plurality of spiral inclined walls are provided on the outer peripheral wall of the light mixing part, and the plurality of spiral inclined walls are arranged along the circumference of the light mixing part, and the spiral inclined walls are spirally provided along the axial direction of the light mixing part. When light enters the inside of the light mixing part from the light incident surface, the plurality of spiral inclined walls can cooperate to reflect the light to transmit the light to the light-emitting surface. The provision of the plurality of spiral inclined surfaces can increase the number of reflections of the light inside the light mixing part, so that the light can be more effectively mixed within a limited distance, thereby improving the light mixing efficiency of the light mixing part, which not only shortens the length of the light guide 1000 while ensuring sufficient light mixing, thereby meeting the compactness requirement of the headlight, but also enables the light guide 1000 to emit light evenly, reduces light loss, and improves the lighting effect of the headlight.

By connecting the connecting portion 210 to one end of the main body 100 in the height direction, and extending the connecting portion 210 in the height direction, it is difficult for the light inside the main body 100 to enter the first mounting member 200 after being reflected by the inner wall thereof, thereby reducing the possibility that the first mounting member 200 changes the propagation path of the light inside the light guide 1000, and making the surface of the light guide 1000 illuminated. The possibility of bright spots and dark areas is greatly reduced, thereby improving the lighting effect of the car lamp and optimizing the lighting function of the vehicle; at the same time, one end of the extension part 220 is connected to the connecting part 210, and the other end is connected to the mounting part 230, and the main body 100 is installed and fixed in the car lamp through the mounting part 230; and by arranging the extension part 220 and the mounting part 230 on one side of the main body 100 along the height direction, the possibility of the user observing the extension part 220 and the mounting part 230 through the main body 100 when the light guide 1000 is in a non-luminous state is reduced, thereby improving the overall aesthetics of the vehicle.
