Description

Technical Field

[0002] As people's demands for car appearance increase, long light guides are increasingly being used in automotive lighting as an aesthetically pleasing optical solution that can perfectly achieve a long, narrow shape. However, long light guides generate considerable heat during use. Current technologies often dissipate heat by placing heat sinks at the ends of the light guide. But due to the length of the light guide, the heat sinks at the ends are generally ineffective at dissipating heat, easily leading to heat buildup. This heat cannot be dissipated in time, and over time, the long light guide is prone to ablation. This not only compromises the stability of the light guide installation but also affects its lighting performance, and its light distribution performance fails to meet regulatory requirements.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0048] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0049] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0050] Long light guides generate a lot of heat during use. Current technology often uses heat sinks at the ends of the light guides to dissipate heat. However, due to the long length of the light guides, the heat sinks at the ends are not very effective at dissipating heat, which can easily cause heat to accumulate and not dissipate in time. Over time, this can lead to ablation of the light guides, which is not only detrimental to the stability of the installation, but also affects the lighting effect and the light distribution performance cannot meet regulatory requirements.

[0051] To address the aforementioned technical problems, this application provides an optical guide mounting structure for mounting a long optical guide. The optical guide mounting structure includes clamping brackets and channel spacers. Two clamping brackets are arranged opposite each other and fixedly connected to clamp the long optical guide. Channel spacers are disposed between the clamping brackets and the long optical guide to separate them and form a heat dissipation space between them. Multiple channel spacers are spaced along the length of the long optical guide to divide the heat dissipation space into multiple interconnected heat dissipation channels. By setting the channel spacers, the clamping brackets and the long optical guide are separated, avoiding large-area contact between them, thus suspending the long optical guide and forming a heat dissipation space between them. Heat can be dissipated in a timely manner, and the heat dissipation channels guide the heat, enabling it to be quickly and efficiently discharged from the heat dissipation space. This will be described in detail below.

[0052] See Figure 1 , Figure 4 as well as Figure 7 The light guide mounting structure is used to install the long light guide 10. The light guide mounting structure includes a clamping bracket 1001 and a channel spacer 110. Two clamping brackets 1001 are arranged opposite each other and are fixedly connected to clamp the long light guide 10. The channel spacer 110 is disposed between the clamping bracket 1001 and the long light guide 10 to separate the clamping bracket 1001 and the long light guide 10, and to form a heat dissipation space 120 between the clamping bracket 1001 and the long light guide 10. Multiple channel spacers 110 are spaced along the length of the long light guide 10 to divide the heat dissipation space 120 into multiple interconnected heat dissipation channels 1201.

[0053] For ease of explanation, in the following embodiments, the length direction of the long light guide 10 is denoted as the Y-axis direction, the main light output direction of the long light guide 10 is denoted as the X-axis direction, and the two clamping brackets 1001 are clamped on both sides of the long light guide 10 in the Z-axis direction. In practical applications, the X-axis direction is the front-to-back direction of the vehicle, the Y-axis direction is the left-to-right direction of the vehicle, and the Z-axis direction is the up-to-down direction of the vehicle, which is also the vertical direction (parallel to the direction of gravity). In addition, the channel spacer 110 is disposed between the clamping bracket 1001 and the elongated light guide 10. In the following embodiments, the channel spacer 110 is disposed on the clamping bracket 1001 as an example. In actual processing, the channel spacer 110 and the clamping bracket 1001 can be integrally molded by injection molding, or the channel spacer 110 can be connected to the clamping bracket 1001 by bonding or snap-fitting, and it is not limited to these. In some embodiments, the channel spacer 110 can also be disposed on the elongated light guide 10 and integrally molded with the elongated light guide 10, which is beneficial to improving the structural strength of the elongated light guide 10 and avoiding local sagging of the elongated light guide 10 due to excessive length, and it is not limited to these.

[0054] By setting the channel spacer 110, the clamping bracket 1001 and the long light guide 10 are separated, avoiding large-area contact between the clamping bracket 1001 and the long light guide 10, thus suspending the long light guide 10 and forming a heat dissipation space 120 between them. The heat generated by the long light guide 10 during use can be dissipated in time (the clamping bracket 1001 does not have large-area contact with the long light guide 10 and will not block the heat dissipation). At the same time, the channel spacer 110 is provided at intervals along the length of the long light guide 10, dividing the heat dissipation space 120 into multiple heat dissipation channels 1201. The heat dissipation channels 1201 have a heat guiding effect, which can quickly and timely dissipate heat from the heat dissipation space 120 and avoid heat accumulation.

[0055] It is worth mentioning that the elongated light guide 10 has a light-incident end (the end where light enters, denoted as the first end 1301). The light-incident end is close to the light source, meaning that the light-incident end receives more heat. The heat gradually decreases from the first end 1301 towards the second end 1302 (the end away from the light-incident end; of course, in some embodiments, both ends of the elongated light guide 10 can be light-incident ends, and the second end 1302 can refer to the middle part of the elongated light guide 10). Therefore, there is a tendency for heat to diffuse along the first end 1301 towards the second end 1302. The potential refers to the existence of fluid flow; during the flow of fluid (i.e. heat), it will pass through each heat dissipation channel 1201 in sequence. Under the guidance of the heat dissipation channel 1201, the heat is gradually discharged (at the same time, it can quickly remove the original heat of each heat dissipation channel 1201). It can orderly and quickly discharge the heat in the heat dissipation space 120, avoid heat accumulation, improve the overall heat dissipation effect of the long light guide 10, reduce the risk of ablation of the long light guide 10, and help improve the service life and lighting effect of the long light guide 10.

[0056] It should be noted that adjacent heat dissipation channels 1201 are interconnected, ensuring that heat is sequentially transferred from the first end 1301 to the second end 1302. In some embodiments, such as... Figure 1 as well as Figure 7 As shown, the reflective teeth of the long light guide 10 and the clamping bracket 1001 can be spaced apart to ensure the connection between adjacent heat dissipation channels 1201. However, this is not the only option; other arrangements are possible in some other embodiments.

[0057] Furthermore, when the elongated light guide 10 makes large-area contact with the clamping bracket 1001, the contact interface (the contact interface between the elongated light guide 10 and the clamping bracket 1001) will disrupt the total internal reflection transmission of light inside the elongated light guide 10 due to refractive index matching issues. This causes the light to fail to emit in the preset direction, reducing the brightness and affecting the overall uniformity of illumination. In this embodiment, the clamping bracket 1001 and the elongated light guide 10 are separated by the channel spacer 110, avoiding large-area contact between the elongated light guide 10 and the clamping bracket 1001. A heat dissipation channel 1201 is formed between two adjacent channel spacers 110, allowing the light to undergo normal total internal reflection and ensuring that the light can emit in the predetermined direction, thus improving the illumination effect.

[0058] In some embodiments, the side of the channel spacer 110 away from the clamping bracket 1001 is curved, that is, the channel spacer 110 contacts the long light guide 10 through a curve. The contact between the channel spacer 110 and the long light guide 10 is a line contact or a point contact (set according to the specific shape of the curved surface). This has little impact on the total internal reflection of the light inside the long light guide 10, which is beneficial to improving the lighting effect.

[0059] It is worth mentioning that the line contact or point contact between the channel spacer 110 and the elongated light guide 10 has a smaller contact area than the surface contact, which is conducive to heat dissipation and has a greater pressure. This results in a greater clamping force on the elongated light guide 10, which helps to improve the stability of the elongated light guide 10 and improves the final lighting effect.

[0060] It should be noted that the fixed connection between the two clamping brackets 1001 can be achieved by means of screws 41 (the screws 41 and related structures used for screw 41 connection are all referred to by the same designation in this application; this is only for simplification and ease of understanding, and does not mean that every screw 41 is the same, but can be of different models), etc., and no specific limitation is made here. The side of the channel spacer 110 away from the clamping bracket 1001 is the side of the channel spacer 110 that contacts the elongated light guide 10, which is the top of the channel spacer 110.

[0061] See Figure 4 The two ends of the long light guide 10 along its length are designated as the first end 1301 and the second end 1302. The light-incident end of the long light guide 10 is the first end 1301. In the direction from the first end 1301 to the second end 1302, the spacing between two adjacent channel spacers 110 gradually decreases.

[0062] In this embodiment, the spacing between two adjacent channel spacers 110 gradually decreases. Specifically, from the first end 1301 towards the second end 1302, the heat dissipation channel 1201 becomes smaller (i.e., the distance between the two channel spacers 110 forming the heat dissipation channel 1201 decreases). That is, the heat dissipation channel 1201 closer to the first end 1301 is larger, and the closer to the first end 1301, the more heat is generated, allowing for timely and rapid heat dissipation. As heat propagates (away from the first end 1301), the heat flow decreases. However, due to the smaller heat dissipation channel 1201, according to Bernoulli's principle, the smaller heat dissipation channel 1201 increases the flow rate of heat passing through it, also enabling timely and rapid heat dissipation. This arrangement improves the overall heat dissipation effect along the length of the long light guide 10.

[0063] In some embodiments, the channel spacer 110 is disposed on the surface of the clamping bracket 1001 facing the elongated light guide 10, and the side of the channel spacer 110 away from the clamping bracket 1001 is curved and recessed towards the clamping bracket 1001, so as to form a heat dissipation cavity 1101 between the channel spacer 110 and the elongated light guide 10. Figure 3 As shown.

[0064] In this embodiment, a groove (i.e., a heat dissipation cavity 1101) is formed on the top of the channel spacer 110, which further reduces the contact area with the elongated light guide 10. The heat dissipated by the part of the elongated light guide 10 corresponding to the groove can be discharged through the groove, effectively improving the heat dissipation effect of the elongated light guide 10.

[0065] It is worth mentioning that when the top of the channel spacer 110 contacts the long light guide 10, both ends of the groove contact the long light guide 10, and two line contacts are formed between the channel spacer 110 and the long light guide 10. This not only improves the heat dissipation effect of the long light guide 10, but also improves the stability of the clamping bracket 1001 clamping the long light guide 10, that is, it improves the stability of the installation of the long light guide 10.

[0066] See Figure 4 In a three-dimensional coordinate system, two clamping brackets 1001 are positioned opposite each other on both sides of the elongated light guide 10 along the Z-axis. The elongated light guide 10 extends along the Y-axis, and the two ends of the elongated light guide 10 along the Y-axis are denoted as the first end 1301 and the second end 1302. The light-incident end of the elongated light guide 10 is the first end 1301. In the Y-axis direction, the channel spacer 110 extends in a spiral shape. The channel spacers 110 corresponding to the two clamping brackets 1001 are in one-to-one correspondence. The distance between the two corresponding channel spacers 110 in the Z-axis direction gradually increases from the first end 1301 toward the second end 1302.

[0067] In this embodiment, the channel spacers 110 on the two clamping brackets 1001 are in one-to-one correspondence, that is, the channel spacer 110 on one clamping bracket 1001 corresponds vertically to the channel spacer 110 on the other clamping bracket 1001 in the figure, that is, the two corresponding channel spacers 110 form a group; the spacing between the two corresponding channel spacers 110 in the Z-axis direction gradually increases along the direction from the first end 1301 to the second end 1302, that is, the two channel spacers 110 are in... Figure 4 From the perspective of the tilted figure-eight arrangement, the channel spacers 110, arranged in this way, can better guide the heat during the heat transmission process, and the channel spacers 110 will not interfere with the heat.

[0068] To facilitate understanding, a counterexample is given below, when the channel spacer 110 is as follows: Figure 2In the arrangement shown, the direction of heat propagation from the first end 1301 to the second end 1302 (from right to left in the figure) has a large angle (90°) with the direction of heat discharge from the heat dissipation channel 1201 (perpendicular to the paper in the figure). Heat needs to change direction significantly to be discharged, and the arrangement of the channel spacer 110 will hinder the diffusion and propagation of heat. However, in this application, with the arrangement of two channel spacers 110, heat only needs to change direction slightly to be discharged from the heat dissipation channel 1201, which is conducive to the rapid discharge of heat.

[0069] It is worth mentioning that during the heat transfer process, the heat first passes through the two ends with the smaller distance (the two ends of the two channel spacers 110 that are close to each other). Figure 4 From the perspective of the two corresponding channel spacers 110 on the right side, it can increase the propagation velocity and then enter the two ends with larger spacing (corresponding to the two ends of the two channel spacers 110 that are farther apart). Figure 4 (From the left side of the two channel spacers 110 in the viewpoint), it can quickly dissipate heat.

[0070] It should be noted that the channel spacer 110 extends in a spiral shape along the Y-axis direction, such as... Figure 4 As shown, a projection plane perpendicular to the X-axis is set, and the orthographic projection of the channel spacer 110 on the projection plane is tilted. In the Y-axis direction, the channel spacer 110 can cover a longer strip of light guide 10, improving the stability of the strip of light guide 10; and it will not affect the size of the contact area between the channel spacer 110 and the strip of light guide 10, and will not affect the heat dissipation performance.

[0071] In some embodiments, for ease of explanation, the channel spacer 110 on the first support 20 is referred to as the first channel spacer 223, and the channel spacer 110 on the second support 30 is referred to as the second channel spacer 321. The first channel spacer 223 and the second channel spacer 321 can be in one-to-one correspondence, that is, the first channel spacer 223 and the second channel spacer 321 are arranged opposite to each other on both sides of the elongated light guide 10 in the Z-axis direction. The first channel spacer 223 and the second channel spacer 321 can also be arranged at intervals in the Y-axis direction, and are not limited thereto.

[0072] See Figure 5-6 The channel spacer 110 is disposed on the surface of the clamping bracket 1001 facing the long light guide 10, and the channel spacer 110 is provided with multiple arc-shaped notches 1102 on the side away from the clamping bracket 1001. The multiple arc-shaped notches 1102 are spaced apart along the extension direction of the channel spacer 110 to connect two adjacent heat dissipation channels 1201.

[0073] By setting the arc-shaped notch 1102, the contact area between the channel spacer 110 and the long light guide 10 can be reduced, which is conducive to heat dissipation; at the same time, by setting the arc-shaped notch 1102, two adjacent heat dissipation channels 1201 can be connected, which is also conducive to heat dissipation.

[0074] It is worth mentioning that the shape of the arc-shaped notch 1102 can determine the contact form between the channel spacer 110 and the elongated light guide 10; for example... Figure 6 In the embodiment shown, the top of the channel spacer 110 is in point contact with the elongated light guide 10. The two contact points are denoted as point F and point G. The part of the channel spacer 110 between point F and point G does not contact the elongated light guide 10. Compared with line contact, point contact has a smaller contact area, which is beneficial for heat dissipation and can bring greater pressure, resulting in a greater clamping force on the elongated light guide 10. As mentioned above, the smaller contact area has less impact on the total internal reflection of light inside the elongated light guide 10.

[0075] Of course, in some embodiments, the channel spacer 110 can also be divided into multiple segments, that is, a longer line contact can be divided into multiple shorter line contacts. This is not limited to this, and will not be elaborated here.

[0076] See Figure 7 The two clamping brackets 1001 are respectively referred to as the first bracket 20 and the second bracket 30. The second bracket 30 and the first bracket 20 are arranged sequentially along the direction of gravity. The surface of the first bracket 20 facing the second bracket 30 is provided with a shielding part 23. The shielding part 23 is spaced apart on the backlight side of the long light guide 10. The shielding part 23 extends towards the second bracket 30 along the direction of gravity to form a drainage channel 140 between the end of the shielding part 23 away from the first bracket 20 and the second bracket 30.

[0077] In this embodiment, the second bracket 30 is positioned above the first bracket 20. In practical applications, heat will rise. The shielding part 23 forms a drainage channel 140, which reduces the distance between the backlight side of the first bracket 20 and the second bracket 30. When heat passes through the drainage channel 140, the flow rate can be increased in the narrow area, and the heat can be quickly discharged, thus improving the heat dissipation effect of the long light guide 10. At the same time, the shielding part 23 can also prevent the heat discharged through the drainage channel 140 from returning to the vicinity of the long light guide 10, avoiding the disorder of heat flow and reducing the impact of the discharged heat accumulating on the long light guide 10.

[0078] In some embodiments, the protrusion height of the channel spacer 110 is h, which satisfies: 0.15 mm ≤ h ≤ 0.25 mm.

[0079] When the value of h is less than 0.15 mm, the distance between the long light guide 10 and the inner surface of the clamping bracket 1001 (the surface of the clamping bracket 1001 facing the long light guide 10, i.e. the surface of the clamping bracket 1001 used to install the channel spacer 110) is too small. In practical applications, the long light guide 10 is prone to contact with the inner surface of the clamping bracket 1001 under vibration, affecting the heat dissipation effect and also affecting the total internal reflection effect of the light inside the long light guide 10, which is not conducive to improving the lighting effect. When the value of h is greater than 0.25 mm, the distance between the long light guide 10 and the inner surface is too large. There will be a large gap between the long light guide 10 and the inner surface, resulting in poor static visual effect and light leakage when lit.

[0080] It should be noted that the protrusion height of the channel spacer 110 is the gap width between the long light guide 10 and the clamping bracket 1001. In some embodiments, when the protrusion heights of the various channel spacers 110 are inconsistent, the value of h is the protrusion height of the part of the channel spacer 110 that is in contact with the long light guide 10.

[0081] See Figure 7 The dimension of the shielding part 23 in the Z-axis direction is H1, and the minimum dimension of the part of the two clamping brackets 1001 used to clamp the long light guide 10 in the Z-axis direction is H2, satisfying: H1≥H2.

[0082] The blocking part 23 is located on the backlight side of the long light guide 10, and H1≥H2, that is, the blocking part 23 can block the internal structure of the backlight side of the long light guide 10, preventing the internal structure from being seen through the long light guide 10, which is beneficial to improving the static visual effect.

[0083] It should be noted that in this embodiment, one of the two clamping brackets 1001 is provided with a shielding part 23 to shield the internal structure of the backlight side of the long light guide 10. In some embodiments, the two clamping brackets 1001 may also be provided with a shielding part 23 respectively. The two shielding parts 23 are spaced apart in the X-axis direction, and there is an overlap between the orthographic projections of the two shielding parts 23 on the projection plane perpendicular to the X-axis direction. The shielding of the backlight side structure of the long light guide 10 is achieved by the two shielding parts 23, but it is not limited to this.

[0084] In the X-axis direction, the blocking part 23 is spaced apart from the long light guide 10. In the actual product, the long light guide 10 has a light-emitting surface 121 and a reflective tooth arranged opposite to the light-emitting surface 121. The blocking part 23 is spaced apart from the long light guide 10, that is, the blocking part 23 is spaced apart from the reflective tooth. When actually lit, the side of the long light guide 10 with the reflective tooth (that is, the side used to reflect light to the light-emitting surface 121 of the long light guide 10) is prone to heat generation. The spaced arrangement of the blocking part 23 and the long light guide 10 can ensure heat dissipation and improve the heat dissipation performance of the long light guide 10.

[0085] It is worth mentioning that the shielding part 23 is spaced apart from the long light guide 10, that is, the shielding part 23 is spaced apart from the reflective tooth to avoid contact with the reflective tooth. During assembly and use, collision or friction with the reflective tooth is avoided, which can ensure the integrity of the reflective tooth and improve its service life.

[0086] See Figure 7 as well as Figure 10 In some embodiments, the second bracket 30 has a wire groove 33 on its surface facing the first bracket 20, and the wire groove 33 is located on the side of the shielding portion 23 away from the elongated light guide 10; the first bracket 20 has a wire pressing portion 24, which is configured to press the wire bundle 90 into the wire groove 33.

[0087] In this embodiment, the wire groove 33 is located at the outlet of the drainage channel 140. When heat is discharged from the drainage channel 140 (due to the small size of the drainage channel 140, the flow rate of discharged heat is increased), the discharged fluid can carry away the heat generated by the wire harness 90, thereby improving the service life and safety of the wire harness 90.

[0088] In addition, by setting the wire groove 33 on the backlight side of the long light guide 10, it is beneficial to arrange the wire harness 90 neatly, and the wire groove 33 has a protective function for the wire harness 90, which can ensure that the wire harness 90 is not crushed or scratched; in addition, by setting the wire pressing part 24, the wire harness 90 can be restricted in the wire groove 33, preventing the wire harness 90 from falling out of the wire groove 33 and improving the safety of use.

[0089] It is worth mentioning that the wire guide groove 33 is set on the back side of the long light guide 10, that is, the wire guide groove 33 is set on the back of the long light guide 10 (X-axis direction), which avoids the wire guide groove 33 occupying the space in the Z-axis direction, which is conducive to the narrow and long setting of the vehicle headlight and meets the design requirements.

[0090] In some embodiments, the wire clamping part 24 may also be disposed on the second bracket 30, and the wire groove 33 may be disposed on the first bracket 20. It is not limited to this and is selected according to the arrangement of the wire harness 90. It will not be described in detail here.

[0091] On the other hand, see Figure 9 , Figure 11 as well as Figure 14This application also relates to a vehicle lamp, including any of the aforementioned light guide mounting structures, and the vehicle lamp further includes a housing 70; two clamping brackets 1001 are respectively referred to as a first bracket 20 and a second bracket 30. In the main light output direction of the elongated light guide 10, a fixing post 34 is provided on the side of the second bracket 30 away from the elongated light guide 10, and the second bracket 30 is fixedly connected to the housing 70 through the fixing post 34; a first positioning plate 341 and a second positioning groove 342 are provided around the fixing post 34, and the housing 70 is provided with a second positioning plate 71 and a first positioning groove 72. The first positioning plate 341 is inserted into the first positioning groove 72, and the second positioning plate 71 is inserted into the second positioning groove 342; the plate surface 80 of the first positioning plate 341 intersects with the plate surface 80 of the second positioning plate 71, and the plate surface 80 of both the first positioning plate 341 and the second positioning plate 71 are parallel to the X-axis direction, which is parallel to the main light output direction of the elongated light guide 10.

[0092] The surface 80 of the first positioning plate 341 intersects with the surface of the second positioning plate 71. Both the surface 80 of the first positioning plate 341 and the surface of the second positioning plate 71 are parallel to the X-axis direction. That is, by the cooperation of the first positioning plate 341 with the first positioning groove 72 and the second positioning plate 71 with the second positioning groove 342, the relative position of the second bracket 30 and the housing 70 on the YZ plane can be restricted. Finally, the fixed installation in the X-axis direction is achieved by the fixing post 34. This arrangement is beneficial to improving the accuracy of the installation position between the second bracket 30 and the housing 70. The light-emitting surface 121 of the long light guide 10 can be positioned in the designed position, which is beneficial to improving the lighting effect.

[0093] In the actual assembly process, the assembled first bracket 20, second bracket 30 and long light guide 10 are moved along the X-axis toward the housing 70. During the movement, the first positioning plate 341 and the second positioning plate 71 ensure the accuracy of the installation position of the second bracket 30, that is, the accuracy of the installation position of the long light guide 10. The structure is simple and the positioning is accurate. Finally, the installation between the second bracket 30 and the housing 70 is completed by connecting the connector and the fixing post 34.

[0094] It should be noted that the second bracket 30 is connected to the housing 70 through the fixing post 34. The fixing post 34 can be provided with a screw hole 42, and the connection between the second bracket 30 and the housing 70 can be made by screws 41 (connectors). It is not limited to this, and other arrangements can be made in other embodiments. The first positioning plate 341 is inserted into the first positioning groove 72, that is, the plate surface 80 of the first positioning plate 341 abuts against the groove wall of the first positioning groove 72, thereby restricting the relative position of the first positioning plate 341 (i.e., the second bracket 30). The second positioning plate 71 and the second positioning groove 342 are similar, and will not be described in detail here.

[0095] In addition, the plate surface 80 of the first positioning plate 341 is the surface with a larger area, and the plate surface 80 of the second positioning plate 71 is also arranged in the same way; in some embodiments, the first positioning plate 341 and the second positioning plate 71 can be arranged simultaneously in one of the first bracket 20 and the second bracket 30, and correspondingly, the first positioning groove 72 and the second positioning groove 342 are arranged simultaneously on the housing 70. In other embodiments, other forms of arrangement are also possible, not limited to this; at the same time, in some embodiments, the component used for positioning may not be plate-shaped, but may include a surface for positioning (plate surface 80 and groove wall). This embodiment only provides one positioning method.

[0096] In some embodiments, the second bracket 30 is provided with a fixing block 35 on the side near the elongated light guide 10 in the X-axis direction. Correspondingly, the housing 70 is provided with a fixing groove 73. During the assembly process, the fixing block 35 is inserted into the fixing groove 73, which can further improve the stability and accuracy of the installation between the second bracket 30 and the housing 70. The fixing block 35 is located near the elongated light guide 10, which effectively improves the stability of the end of the second bracket 30 near the light-emitting side (i.e., the elongated light guide 10), thereby improving the lighting effect.

[0097] In some embodiments, the fixing post 34 abuts against the housing 70 via a connector; a first reinforcing block 343 is provided on the periphery of the fixing post 34, and the first reinforcing block 343 also abuts against the housing 70; a second reinforcing block 74 is provided on the side of the housing 70 away from the fixing post 34, and a reference plane perpendicular to the X-axis direction is set as the projection plane η, and the orthographic projection of the first reinforcing block 343 on the projection plane η and the orthographic projection of the second reinforcing block 74 on the projection plane η at least partially overlap.

[0098] In this embodiment, the screw 41 is used as an example for discussion. Correspondingly, a screw hole 42 adapted to the screw 41 is provided on the fixing post 34. When the screw 41 is screwed into the screw hole 42, the fixing post 34 and the housing 70 are pressed against each other. Due to the setting of the first reinforcing block 343 and the second reinforcing block 74, when the fixing post 34 and the housing 70 are pressed against each other, the first reinforcing block 343 and the second reinforcing block 74 can press against each other, avoiding deformation of the housing 70 and avoiding excessive screwing. This is beneficial to improving the structural strength while ensuring the accuracy of the installation position of the long light guide 10.

[0099] In some embodiments, the second reinforcing block 74 may be an annular protrusion surrounding the screw 41, etc., without specific limitation.

[0100] In some embodiments, the first positioning plate 341 and the second positioning groove 342 are disposed on both sides of the fixing post 34 in the Y-axis direction, and the Y-axis direction is parallel to the length direction of the long light guide 10.

[0101] This arrangement does not take up space in the Z-axis direction, which is beneficial for the overall narrow and long design of the headlights.

[0102] See Figure 8 , Figure 9 as well as Figure 11-13 In a three-dimensional coordinate system, the elongated light guide 10 extends along the Y-axis. The elongated light guide 10 has a light-incident portion 11, a main body portion 12, and a connecting portion 13. The light-incident portion 11 is connected to the main body portion 12. A light-incident surface is provided at the end of the light-incident portion 11 away from the main body portion 12 (the light-incident end). The main body portion 12 is configured to receive light rays incident through the light-incident surface and emit the light rays from the light-exiting surface 121 of the main body portion 12 along the X-axis. The connecting portion 13 is connected to the end of the light-incident portion 11 near the light-incident surface, and the connecting portion 13 is provided with… A limiting hole 131 is provided; a first bracket 20 is provided on one side of the long light guide 10 in the Z-axis direction; a second bracket 30 is provided on the other side of the long light guide 10 in the Z-axis direction; the second bracket 30 and the first bracket 20 are connected by a connecting structure 40 to clamp the long light guide 10 in the Z-axis direction; at least one of the first bracket 20 and the second bracket 30 is provided with a limiting post 211, which cooperates with the limiting hole 131 to limit the relative position of the long light guide 10 in the XY plane.

[0103] For ease of explanation, the XY plane is a horizontal plane in the following embodiments. In the following embodiments, the example is taken where the axial direction of the limiting post 211 is parallel to the Z-axis direction, that is, the limiting post 211 extends along the Z-axis direction.

[0104] The first bracket 20 and the second bracket 30 are disposed on both sides of the elongated light guide 10 in the vertical direction, and the first bracket 20 and the second bracket 30 are connected by a connecting structure 40. Under the action of the connecting structure 40, the elongated light guide 10 is clamped between the first bracket 20 and the second bracket 30. The first bracket 20 and the second bracket 30 restrict the relative position of the elongated light guide 10 in the Z-axis direction. At the same time, the cooperation between the limiting post 211 and the limiting hole 131 can restrict the relative position of the elongated light guide 10 in the X-axis direction and the Y-axis direction. The clamping of the elongated light guide 10 by the first bracket 20 and the second bracket 30, and the cooperation between the limiting post 211 and the limiting hole 131, help to improve the stability of the installation of the elongated light guide 10 and improve the accuracy of the installation position of the elongated light guide 10.

[0105] In this embodiment, the connecting part 13 is disposed at one end of the light-incident part 11 near the light-incident surface, that is, the connecting part 13 is disposed near the light-incident end of the elongated light guide 10. The limiting hole 131 disposed on the connecting part 13, through cooperation with the limiting post 211, can ensure the accuracy of the installation position between the connecting part 13 and the first bracket 20 and the second bracket 30, that is, ensure the accuracy of the relative position between the light-incident end of the elongated light guide 10 and the first bracket 20 and the second bracket 30. In the subsequent assembly process, it can improve the accuracy and stability of the relative position between the light-incident surface of the elongated light guide 10 and the light source. When lit later, the elongated light guide 10 can better receive the light emitted by the light source (such as LED beads), improving the utilization rate of light and the lighting effect.

[0106] In addition, the connecting part 13 is provided in the light-incident part 11 and not on the main body part 12, so it will not damage the integrity of the main body part 12, that is, it will not affect the propagation of light from the main body part 12, which is conducive to improving the lighting effect.

[0107] It is worth mentioning that, since the first bracket 20 and the second bracket 30 are clamped on both sides of the long light guide 10, the long light guide 10 can be prevented from rotating around the Z-axis to a certain extent, thus improving the stability of the long light guide 10 installation. In addition, in some embodiments, the rotation of the long light guide 10 can be restricted by setting the shape of the limiting post 211 and the limiting hole 131. For example, the limiting post 211 and the limiting hole 131 are square. When the limiting post 211 and the limiting hole 131 are engaged, the long light guide 10 can also be prevented from rotating around the Z-axis, which can also improve the stability of the long light guide 10 installation.

[0108] The first bracket 20 and the second bracket 30 are respectively set on both sides of the vertical direction of the long light guide 10. The first bracket 20 and the second bracket 30 are set separately. In practical applications, the first bracket 20 or the second bracket 30 can be replaced separately, which reduces the subsequent maintenance and repair costs. Moreover, the separate setting makes the structure of each component simple, which is conducive to the installation operation during the assembly process, and reduces the difficulty of parts production and processing, thus improving production efficiency.

[0109] Taking the first bracket 20 with a limiting post 211 as an example, in the actual assembly process, the long light guide 10 is positioned on the first bracket 20 by the cooperation of the limiting post 211 and the limiting hole 131. Then, the second bracket 30 is placed on the other side of the long light guide 10 (the side away from the first bracket 20). Finally, the first bracket 20 and the second bracket 30 are connected by the connecting structure 40, so that the long light guide 10 is clamped between the first bracket 20 and the second bracket 30.

[0110] In some embodiments, the limiting post 211 may also be provided on the second bracket 30, or the limiting post 211 may be provided on both the first bracket 20 and the second bracket 30, which will not be elaborated here.

[0111] It should be noted that the connecting structure 40 is used to connect the first bracket 20 and the second bracket 30. In this embodiment, it can be connected by screws 41, and in some embodiments, it can also be connected by rivets, clips, etc., and is not limited to these. Multiple sets of connecting structures 40 can be arranged along the Y-axis direction. The number of sets of connecting structures 40 is set according to the different lengths of the long light guide 10, so as to ensure that the first bracket 20 and the second bracket 30 are clamped at multiple positions in the Y-axis direction, thereby improving the stability of the installation of the long light guide 10. This will not be elaborated here. At the same time, the long light guide 10 extends along the Y-axis direction, which can be a straight line or a curve, and the design is related to the design of the vehicle headlight. This will not be elaborated here.

[0112] In some embodiments, the main body 12 is provided with a light-incident part 11 and a connecting part 13 at both ends, that is, the long light guide 10 has two light-incident surfaces and light sources are provided at both ends of the long light guide 10. The stability of the installation at the end of the long light guide 10 is achieved by setting the upper limit hole 131 of the connecting part 13. This will not be elaborated here. The relevant settings are made according to the actual lighting requirements of the long light guide 10.

[0113] See Figure 12 as well as Figure 13 A limiting post 211 is disposed on the first bracket 20, and a connecting part 13 is disposed between the first bracket 20 and the second bracket 30; the surface of the first bracket 20 facing the connecting part 13 is provided with a first limiting protrusion 212, and the surface of the second bracket 30 facing the connecting part 13 is provided with a second limiting protrusion 311, and the connecting part 13 is clamped between the first limiting protrusion 212 and the second limiting protrusion 311.

[0114] In this embodiment, by setting the first limiting protrusion 212 and the second limiting protrusion 311, the stability of the connection part 13 installation can be improved (the connection part 13 is clamped between the first limiting protrusion 212 and the second limiting protrusion 311), that is, the stability of the light-incident end (light-incident surface) of the long light guide 10 is ensured, and the long light guide 10 can better receive the light emitted by the light source, which is conducive to improving the lighting effect.

[0115] It should be noted that in the actual assembly process, when the first bracket 20 and the second bracket 30 are connected by the connecting structure 40, the clamping effect of the first limiting protrusion 212 and the second limiting protrusion 311 on the connecting part 13 can be achieved. The structure is simple and easy to use.

[0116] In some embodiments, the second limiting protrusion 311 is arranged in a ring to form a limiting groove 50; the end of the limiting post 211 away from the first bracket 20 passes through the limiting hole 131 and is inserted into the limiting groove 50.

[0117] The second limiting protrusion 311 is arranged in a ring shape, and a limiting groove 50 is formed inside the second limiting protrusion 311. During assembly, the end of the limiting post 211 away from the first bracket 20 is inserted into the limiting groove 50. Through the cooperation between the limiting groove 50 and the limiting post 211, the stability and accuracy of the installation between the first bracket 20 and the second bracket 30 are improved. Since the limiting post 211 also cooperates with the limiting hole 131, the installation accuracy between the limiting post 211 and the connecting part 13 is ensured. The connecting part 13 and the second bracket 30 are both positioned and installed with the first bracket 20 through the limiting post 211. This is beneficial to improving the positioning and installation between the first bracket 20, the second bracket 30, and the connecting part 13 (the light-incident end of the long light guide 10), improving the installation accuracy and stability, and improving the lighting effect.

[0118] In some embodiments, the connecting structure 40 includes a screw 41, a screw hole 42, a connecting hole 43, a positioning post 44, and a positioning hole 45; the screw hole 42 is disposed on the limiting post 211, the connecting hole 43 is disposed at the bottom of the limiting groove 50, and the positioning post 44 and the positioning hole 45 are respectively disposed on the first bracket 20 and the second bracket 30; in the actual assembly process, the long light guide 10 is first initially positioned on the first bracket 20 through the cooperation of the limiting hole 131 and the limiting post 211, and then the second bracket 30 is oriented towards the first bracket 20. As the bracket 20 moves, the positioning post 44 engages with the positioning hole 45 to position the first bracket 20 and the second bracket 30 in the X and Y axes. Simultaneously, the screw hole 42 and the connecting hole 43 become concentric. Finally, the screw 41 passes through the connecting hole 43 and screws onto the screw hole 42, thus connecting the first bracket 20 and the second bracket 30. While the first bracket 20 and the second bracket 30 are connected, the connecting part 13 is also clamped, improving the stability and accuracy of the installation at the end of the long light guide 10.

[0119] In some embodiments, in the X-axis direction, the first bracket 20 sequentially includes a first mounting portion 21 and a first clamping portion 22, and the second bracket 30 sequentially includes a second mounting portion 31 and a second clamping portion 32. A light-incident portion 11 and a main body portion 12 are disposed between the first clamping portion 22 and the second clamping portion 32, and a connecting portion 13 is disposed between the first mounting portion 21 and the second mounting portion 31. A light-blocking portion 221 is provided on the side of the first clamping portion 22 away from the first mounting portion 21. The light-blocking portion 221 extends along the Z-axis direction and is disposed in the area of ​​the first clamping portion 22 corresponding to the light-incident portion 11. A first blocking part 312 is provided on the side of the second mounting part 31 away from the second clamping part 32. The second mounting part 31 is also provided with a second blocking part 313. In the Y-axis direction, the second blocking part 313 is provided on the side of the connecting part 13 close to the main body part 12. The first blocking part 312 and the second blocking part 313 both extend along the Z-axis direction and are both provided in the area of ​​the second mounting part 31 corresponding to the light-incident part 11. The first blocking part 312, the second blocking part 313, the light-blocking part 221, the first mounting part 21 and the second mounting part 31 cooperate to form a heat insulation space 60, and the connecting part 13 is accommodated in the heat insulation space 60.

[0120] In this embodiment, the light-blocking part 221, the first blocking part 312, and the second blocking part 313 are all disposed in the area corresponding to the light-incident part 11. For ease of explanation, the vehicle headlight is divided into a first area and a second area in the Y-axis direction. The light-incident part 11 corresponds to the first area, and the main body part 12 corresponds to the second area. That is, the light-blocking part 221, the first blocking part 312, and the second blocking part 313 are disposed in the first area.

[0121] The light-blocking part 221 is disposed on the side of the first clamping part 22 away from the first mounting part 21, that is, the light-blocking part 221 is disposed on the light-emitting side (the light-emitting side of the vehicle lamp). Since the light-blocking part 221 is disposed in the area of ​​the first clamping part 22 corresponding to the light-incident part 11 (that is, the light-blocking part 221 is disposed on the first clamping part 22 corresponding to the first area), it can block the light-emitting side of the light-incident part 11. In actual lighting and use, some light will be emitted from the light-emitting side of the light-incident part 11. The light-blocking part 221 can block this part of the light, so as to avoid stray light affecting the lighting effect of the main body part 12.

[0122] In this embodiment, the first baffle 312, the second baffle 313, the light-blocking part 221, the first mounting part 21, and the second mounting part 31 cooperate to form a heat insulation space 60. The heat insulation space 60 is set in the first region and forms a heat insulation cavity between the power supply and the main body 12. It can isolate the main body 12 from the power supply, prevent the heat generated by the power supply from entering the area of ​​the main body 12, prevent the main body 12 from deforming due to excessive heat, improve the service life of the main body 12, and help improve the lighting effect.

[0123] It is worth mentioning that the connecting part 13 is housed in the heat-insulating space 60, and the first baffle part 312 and the second baffle part 313 can surround the connecting part 13, which can prevent the connecting part 13 from being disturbed by the outside world and improve the stability of the connection of the connecting part 13. In addition, in some embodiments, the connecting structure 40 can also be housed in the heat-insulating space 60, which can improve the stability of the connection of the connecting structure 40. The setting of the first baffle part 312 and the second baffle part 313 can also enhance the structural strength of the second mounting part 31. When connected by the connecting structure 40 (e.g., screw 41 connection, see the above embodiments for details), the deformation of the second mounting part 31 can be avoided, which can improve the accuracy and stability of the installation position.

[0124] It should be noted that in this embodiment, the light-blocking part 221 is disposed on the first clamping part 22. In some embodiments, the light-blocking part 221 may also be disposed on the second clamping part 32. The first blocking part 312 and the second blocking part 313 are disposed on the second mounting part 31. In some embodiments, they may also be disposed on the first mounting part 21, and are not limited thereto. In addition, the first blocking part 312 and the second blocking part 313 may also be integrally disposed, that is, there is no gap between the first blocking part 312 and the second blocking part 313, which can improve the heat insulation performance of the heat insulation space 60.

[0125] This embodiment only provides one way of forming the heat insulation space 60. In other embodiments, other arrangements can be used to ultimately form the heat insulation space 60 between the power supply and the main body 12. These will not be elaborated here.

[0126] See Figure 13 as well as Figure 14 The light-inlet section 11 is provided with a plug-in block 111 on its periphery, and the first bracket 20 and / or the second bracket 30 are provided with plug-in holes 222, and the plug-in block 111 is adapted to the plug-in hole 222.

[0127] In this embodiment, by providing a plug-in block 111 on the periphery of the light-incident part 11, the plug-in block 111 is adapted to the plug-in hole 222. That is, during assembly, the plug-in block 111 can be plugged into the plug-in hole 222 to fix the relative position of the long light guide 10 on the XY plane, which is beneficial to improving the installation stability of the long light guide 10. At the same time, since the plug-in block 111 is provided on the light-incident part 11, close to the end of the long light guide 10, the installation stability of the light-incident end of the long light guide 10 can be guaranteed, which is beneficial to improving the lighting effect. Moreover, since the plug-in block 111 is provided on the periphery of the light-incident part 11 and not on the main body 12, it will not damage the integrity of the main body 12, that is, it will not affect the propagation of light in the main body 12, which is beneficial to improving the lighting effect.

[0128] It should be noted that in this embodiment, the insertion hole 222 is provided on the first bracket 20. In some embodiments, it may also be provided on the second bracket 30, or both the first bracket 20 and the second bracket 30 may be provided with insertion holes 222. Correspondingly, the insertion block 111 is provided with two, but it is not limited to this.

[0129] See Figure 7 In some embodiments, the surface of the first bracket 20 facing the second bracket 30 is provided with a first receiving groove 224, and the surface of the second bracket 30 facing the first bracket 20 is provided with a second receiving groove 322. The first receiving groove 224 and the second receiving groove 322 cooperate to form an installation space, and the main body 12 and the light-incident part 11 are housed in the installation space.
