[0004] To achieve the above objectives, the present invention proposes a light guiding device, which includes:

The first light-transmitting part is arranged corresponding to the light-emitting and focusing area, and the second light-transmitting part is arranged corresponding to the light-emitting and focusing area.
[0007] In one embodiment, the light-incident end is formed with a plurality of stepped surfaces distributed in a stepped manner, wherein the light-incident focusing area includes at least one of the stepped surfaces, and the stepped surface of the light-incident focusing area is formed with the first light-incident ripple; the light-incident homogenizing area includes at least one of the stepped surfaces, and the stepped surface of the light-incident homogenizing area is formed with the first light-homogenizing ripple.
[0008] In one embodiment, the first light-focusing pattern includes a plurality of arrayed first light-incoming recesses, and the first light-uniforming pattern includes a plurality of arrayed second light-incoming recesses, wherein the recess depth of the first light-incoming recess is greater than the recess depth of the second light-incoming recess.
[0009] In one embodiment, the stepped surface is inclined toward the light-emitting end along the direction from the light-uniform channel to the light-concentrating channel, the light-emitting end forms an inclined surface, the inclined surface is inclined toward the lampshade structure along the direction from the light-uniform channel to the light-concentrating channel, and the inclined surface sequentially forms the light-emitting uniform light area and the light-emitting concentrating light area along the direction from the light-uniform channel to the light-concentrating channel.
[0010] In one embodiment, the second light-focusing pattern is formed with a plurality of first light-emitting protrusions, and the second light-uniforming pattern includes a plurality of second light-emitting protrusions, wherein the protrusion height of the first light-emitting protrusions is greater than the protrusion height of the second light-emitting protrusions.
[0011] In one embodiment, the light-emitting focusing area has a plurality of protruding first light-emitting racks, which are arranged sequentially along the extension direction of the inclined surface. The extension direction of each first light-emitting rack is perpendicular to the extension direction of the inclined surface. Each first light-emitting rack has a plurality of first light-emitting protrusions arranged sequentially along the extension direction of the first light-emitting rack. The light-emitting uniform area has a plurality of protruding second light-emitting racks, which are arranged sequentially along the extension direction of the inclined surface. The extension direction of each second light-emitting rack is perpendicular to the extension direction of the inclined surface. Each second light-emitting rack has a plurality of second light-emitting protrusions arranged sequentially along the extension direction of the second light-emitting rack.
[0012] In one embodiment, a third light-focusing pattern is formed on the side of the first light-transmitting portion near the light-emitting and light-focusing area, and the third light-focusing pattern includes a plurality of light-transmitting protrusions protruding toward the light-emitting and light-focusing area.
[0013] In one embodiment, the first light-transmitting portion has a plurality of light-transmitting teeth protruding toward the side near the light-emitting and focusing area. The plurality of light-transmitting teeth are arranged sequentially along the extension direction of the first light-transmitting portion, and a plurality of light-transmitting protrusions are formed on each of the light-transmitting teeth arranged in parallel along the vertical direction.
[0014] This utility model also proposes a turn signal, which includes a light source and the aforementioned light guide device, wherein the light source is disposed near the light input end of the light guide device.
[0015] This utility model also proposes a vehicle that uses the aforementioned turn signals.
[0016] The technical solution of this utility model, through the first and second light-transmitting parts arranged at an angle, allows light emitted from the light source and passing through the light guide lens to be refracted in two directions, enabling the light to exit from the rear and side of the vehicle respectively. This provides more sufficient illumination for the turn signals with large curvatures, thereby effectively improving the lighting effect of the turn signals. The light-incident end has a light-uniforming area and a light-concentrating area, and the light-exiting end has a light-uniforming area and a light-concentrating area. The light-uniforming area and the light-concentrating area are correspondingly arranged, and a concentrating channel is formed between them. A first concentrating pattern is formed on the light-incident concentrating area. When the light source enters from the light-incident concentrating area, the light is concentrated by the first concentrating pattern. Then, the light source passes through the concentrating channel and exits from the light-exit concentrating area, where the second concentrating pattern further concentrates the light emitted. The first light-transmitting section is positioned close to the light-emitting focusing area. Light emitted from the light source converges on both sides of the light-incident and light-emitting focusing areas before striking the first light-transmitting section. This allows the light that needs to be refracted by the first light-transmitting section to be more focused, resulting in higher brightness of the light after refraction, thereby further improving the lighting effect of turn signals with large bending arcs. A first light-diffusing pattern is formed on the light-incident uniform light area. When the light source enters from the light-incident uniform light area, the light is diffused by the first light-diffusing pattern on the light-incident uniform light area. Then, the light source passes through the uniform light channel and exits from the light-emitting uniform light area. The second light-emitting focusing pattern on the light-emitting focusing area further diffuses the light emitted from the light-emitting focusing area. The second light-transmitting part is positioned close to the light-emitting and focusing area. The light emitted from the light source is diffused on both sides of the light-incident and light-emitting uniform areas before being directed towards the first and second light-transmitting parts. This allows the light illuminating the first and second light-transmitting parts to be more uniform, thereby making the light refracted from the first and second light-transmitting parts more uniform and further improving the lighting effect of turn signals with large bending arcs.

[0031] Currently, due to vehicle styling requirements, turn signals need to extend towards the sides of the vehicle, resulting in a significant bend in the turn signal. However, since turn signals typically rely on a single light source, it's difficult for a single light source to adequately illuminate such a bend, leading to poor lighting performance.
[0032] This utility model proposes a light guide device 100, a turn signal, and a vehicle.
[0033] Please see Figures 1 to 7In one embodiment of this utility model, the light guiding device 100 includes a light guiding lens 10 and a lampshade structure 20; wherein, the two ends of the light guiding lens 10 are a light-incident end 11 and a light-exiting end 12, respectively; the light-incident end 11 forms a light-incident focusing area 13 and a light-incident uniform light area 14; the light-exiting end 12 forms a light-exit focusing area 15 and a light-exit uniform light area 16; a focusing channel is formed between the light-incident focusing area 13 and the light-exit focusing area 15; a uniform light channel is formed between the light-incident uniform light area 14 and the light-exit uniform light area 16; and the light-incident focusing area 13 forms... The first light-focusing pattern 131, the light-emitting focusing area 15 has a second light-focusing pattern 151, the light-incident uniform area 14 has a first light-uniforming pattern 141, and the light-emitting uniform area 16 has a second light-uniforming pattern 161; the lampshade structure 20 includes a light-transmitting cover 21 protruding away from the light-emitting focusing area 15, the light-transmitting cover 21 includes a first light-transmitting part 211 and a second light-transmitting part 212 arranged at an angle to each other, the first light-transmitting part 211 is arranged corresponding to the light-emitting focusing area 15, and the second light-transmitting part 212 is arranged corresponding to the light-emitting focusing area 15.
[0034] Understandably, the light guide device 100 of this utility model can be applied to equipment that requires light guidance, such as turn signals or other lamps. This utility model is described using the application of the light guide device 100 to a turn signal as an example. In a turn signal, a light source 200 can be provided at a position near the light-incident end 11 of the light guide device 100. The light source 200 is used to illuminate the light-incident end 11.
[0035] In the technical solution of this utility model, the light-transmitting cover 21, through the first light-transmitting part 211 and the second light-transmitting part 212 arranged at an angle, can refract light emitted from the light source 200 and passing through the light guide lens 10 into two directions, so that the light can be emitted from the rear and side of the vehicle respectively, thereby illuminating the turn signals with large curvatures more fully and effectively improving the lighting effect of the turn signals. The front and rear ends of the light guide lens 10 are the light-incident end 11 and the light-exit end 12, respectively. The light-incident end 11 forms a light-incident uniform light area 14 and a light-incident focusing light area 13, and the light-exit end 12 forms a light-exit uniform light area 16 and a light-exit focusing light area 15. The light-incident uniform light area 14 and the light-exit uniform light area 16 are arranged correspondingly, and a focusing light channel is formed between the light-incident focusing light area 13 and the light-exit focusing light area 15. A first focusing pattern 131 is formed on the light-incident focusing area 13. When the light source 200 enters from the light-incident focusing area 13, the light can be concentrated by the first focusing pattern 131 on the light-incident focusing area 13. Then, the light source 200 passes through the focusing channel and exits from the light-exit focusing area 15. The light emitted from the light-exit focusing area 15 is concentrated by the second focusing pattern 151 on the light-exit focusing area 15. The first light-transmitting part 211 is set close to the light-exit focusing area 15. The light emitted from the light source 200 is concentrated on both sides of the light-incident focusing area 13 and the light-exit focusing area 15, and then shines on the first light-transmitting part 211. This can concentrate the light that needs to be refracted by the first light-transmitting part 211, so that the light after being refracted by the first light-transmitting part 211 has higher brightness, thereby further improving the lighting effect of the turn signal with a large bending arc. A first uniform light pattern 141 is formed on the incident light uniform light area 14. When the light source 200 enters from the incident light uniform light area 14, the light can be more diffused by the first uniform light pattern 141 on the incident light uniform light area 14. Then, the light source 200 passes through the uniform light channel and exits from the exit light uniform light area 16. The light emitted from the exit light focusing area 15 is further diffused by the second focusing light pattern 151 on the exit light focusing area 15. The second light-transmitting part 212 is set close to the exit light focusing area 15. The light emitted from the light source 200 is diffused on both sides of the incident light uniform light area 14 and the exit light uniform light area 16, and then shines on the first light-transmitting part 211 and the second light-transmitting part 212. The light illuminating the first light-transmitting part 211 and the second light-transmitting part 212 can be more uniform, thereby making the light refracted from the first light-transmitting part 211 and the second light-transmitting part 212 more uniform, and further improving the lighting effect of the turn signal with a large bending arc.
[0036] In one embodiment, the light-incident end 11 is formed with a plurality of stepped surfaces 111 distributed in a stepped manner. The light-incident focusing area 13 includes at least one stepped surface 111, and the stepped surface 111 of the light-incident focusing area 13 is formed with a first light-focusing pattern 131. The light-incident homogenizing area 14 includes at least one stepped surface 111, and the stepped surface 111 of the light-incident homogenizing area 14 is formed with a first light-homogenizing pattern 141.
[0037] Specifically, such as Figure 1 As shown, the light-incident end 11 has a plurality of stepped surfaces 111 arranged in a stepped manner. The stepped surfaces 111 arranged in a stepped manner can increase the area of light entering the light-incident end 11, thereby increasing the amount of light entering the light guide lens 10, thereby increasing the intensity of light emitted from the light guide lens 10, and thus improving the lighting effect of the turn signal.
[0038] In one embodiment, the first light-focusing pattern 131 includes a plurality of arrayed first light-incoming recesses 1311, and the first light-uniforming pattern 141 includes a plurality of arrayed second light-incoming recesses 1411, wherein the recess depth of the first light-incoming recesses 1311 is greater than the recess depth of the second light-incoming recesses 1411.
[0039] Specifically, such as Figure 4 and Figure 5 As shown, multiple first light-inlet recesses 1311 and multiple second light-inlet recesses 1411 are arrayed, which allows light to enter the light guide lens 10 more evenly from the light-inlet focusing area 13 and the light-inlet uniform area 14, and thus exit the lamp cover structure 20 more evenly, thereby improving the lighting effect of the turn signal. The first light-inlet recesses 1311 and the second light-inlet recesses 1411 can be equivalent to concave lenses. According to the optical path principle of concave lenses, when the recess depth of the first light-inlet recess 1311 is greater than the recess depth of the second light-inlet recess 1411, compared with the light entering the second light-inlet recess 1411, the first light-inlet recess 1311 can concentrate the light more, thus making the light emitted from the light-out focusing area 15 more concentrated, while the second light-inlet recess 1411 can diffuse the light more, thus making the light emitted from the light-out uniform area 16 more diffuse.
[0040] In one embodiment, the stepped surface 111 is inclined toward the light-emitting end 12 along the direction from the light-uniform channel to the light-concentrating channel. The light-emitting end 12 forms an inclined surface 121, which is inclined toward the lampshade structure 20 along the direction from the light-uniform channel to the light-concentrating channel. The inclined surface 121 is sequentially formed with a light-emitting uniform light area 16 and a light-emitting concentrating light area 15 along the direction from the light-uniform channel to the light-concentrating channel.
[0041] Specifically, such as Figure 1 As shown, both the stepped surface 111 and the inclined surface 121 are inclined from right to left and backward. The inclined surface 121 allows the light energy emitted from the inclined surface 121 to be directed at the lamp cover structure 20 at a more suitable angle, thereby making the light distribution at the rear and sides of the vehicle more uniform, avoiding local over-brightness or under-brightness, and improving the overall illumination uniformity and brightness of the turn signal.
[0042] In one embodiment, the second light-focusing pattern 151 is formed with a plurality of first light-emitting protrusions 1511, and the second light-uniforming pattern 161 includes a plurality of second light-emitting protrusions 1611, wherein the protrusion height of the first light-emitting protrusions 1511 is greater than the protrusion height of the second light-emitting protrusions 1611.
[0043] Specifically, such as Figure 2 and Figure 3 As shown, the first light-emitting protrusion 1511 and the second light-emitting protrusion 1611 can be equivalent to convex lenses. According to the optical path principle of convex lenses, when the protrusion height of the first light-emitting protrusion 1511 is greater than that of the second light-emitting protrusion 1611, compared with the light entering the first light-emitting protrusion 1511, the first light-emitting protrusion can concentrate the light more, thus making the light emitted from the light-emitting focusing area 15 more concentrated. The second light-emitting protrusion 1611 can diffuse the light more, thus making the light emitted from the light-emitting uniform area 16 more diffuse.
[0044] In one embodiment, the light-emitting focusing region 15 has a plurality of protruding first light-emitting racks 1512, which are arranged sequentially along the extension direction of the inclined surface 121. The extension direction of each first light-emitting rack 1512 is perpendicular to the extension direction of the inclined surface 121. Each first light-emitting rack 1512 has a plurality of first light-emitting protrusions 1511 arranged sequentially along the extension direction of the first light-emitting rack 1512. The light-emitting uniform region 16 has a plurality of protruding second light-emitting racks 1612, which are arranged sequentially along the extension direction of the inclined surface 121. The extension direction of each second light-emitting rack 1612 is perpendicular to the extension direction of the inclined surface 121. Each second light-emitting rack 1612 has a plurality of second light-emitting protrusions 1611 arranged sequentially along the extension direction of the second light-emitting rack 1612.
[0045] Specifically, such as Figure 2 and Figure 3 As shown, the multiple parallel first light-emitting racks 1512 and second light-emitting racks 1612 can be regarded as a grating-like structure. The multiple first light-emitting racks 1512 and multiple second light-emitting racks 1612 make the light emitted onto the lamp cover structure 20 more uniform, avoiding the occurrence of local over-brightness or under-brightness, and improving the overall lighting uniformity and brightness of the turn signal.
[0046] In one embodiment, a third light-concentrating pattern 2111 is formed on the side of the first light-transmitting portion 211 near the light-concentrating area 15. The third light-concentrating pattern 2111 includes a plurality of light-transmitting protrusions 2112 protruding toward the light-concentrating area 15.
[0047] Specifically, such as Figure 7As shown, the multiple light-transmitting protrusions 2112 on the first light-transmitting part 211 can further converge and guide the light rays incident from the first light-transmitting part 211, thereby increasing the brightness of the light rays emitted from the first light-transmitting part 211 and further improving the lighting effect of the turn signal.
[0048] In one embodiment, the first light-transmitting portion 211 has a plurality of light-transmitting teeth 2113 protruding from the side near the light-emitting focusing area 15. The plurality of light-transmitting teeth 2113 are arranged sequentially along the extension direction of the first light-transmitting portion 211, and a plurality of light-transmitting protrusions 2112 arranged vertically in parallel are formed on each light-transmitting tooth 2113.
[0049] Specifically, such as Figure 6 As shown, the multiple parallel light-transmitting racks 2113 can be regarded as a grating-like structure. The multiple light-transmitting racks 2113 enable light to be emitted more evenly from the first light-transmitting part 211, avoiding local over-brightness or under-brightness, and improving the overall uniformity and brightness of the turn signal illumination.
