[0043] The following will be combined with the accompanying drawings to clearly and completely describe the embodiments of this application. Obviously, the described embodiments are only embodiments of one area of ​​this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0044] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0045] As mentioned in the background technology section, the ADB modules currently on the market are mainly single-light modules, which is not conducive to the development trend of multifunctional integration of vehicle lights.

[0046] In addition, the current implementation scheme of the ADB module is usually: 1. The light beam is converged at the focal point of the outer lens through the light-guiding teeth, and then the light beam at the focal point is projected through the outer lens. The light-guiding teeth of this scheme are relatively long, resulting in low strength of the light-guiding teeth and difficulty in processing; 2. A focusing lens is set in front of the light source, and then the light is projected through the outer lens. However, the focal length of the outer lens is often required to ensure the maximum light intensity of the outgoing light beam, and the outer lens is required to have a certain size to collect the light beam converged at its focal point. This results in the ADB module being very narrow in size and having extremely low light efficiency.

[0047] Based on the above, this application provides a vehicle light module, such as Figure 1 As shown, the vehicle light module includes: a high beam module 100, a low beam module 200, an outer lens 300 and a sunshade 400. Figure 2 As shown, the outer lens 300 includes a high beam area 301 and a low beam area 302. The high beam area 301 is a focus lens, and the low beam area 302 is a focal line lens. The sunshade 400 is located between the high beam module 100 and the low beam module 200 to prevent cross-light between the high beam module 100 and the low beam module 200.

[0048] The high beam module 100 includes a first light source 110 and a first optical unit 120. At least a portion of the light emitting area of ​​the first light source 110 emits a first light beam in response to a high beam control command, so that the first light beam has an anti-glare function. The first optical unit 120 receives the first light beam and causes the first light beam to be emitted from the high beam area 301 of the outer lens 300 as a high beam beam, thereby realizing an anti-glare high beam lighting function. Figure 3 As shown. That is, the first optical unit 120 and the high-beam region 301 of the outer lens 300 transmit and shape the first light beam with an anti-glare function, emitting it in a high-beam pattern, thereby achieving an anti-glare high-beam lighting function. It should be noted that at least a portion of the light-emitting area of ​​the first light source 110 emits the first light beam in response to a high-beam control command. For example, when a vehicle is driving and in the high-beam state, the light-emitting area of ​​the first light source 110 corresponding to the driver of the oncoming vehicle is turned off, and the remaining light-emitting areas emit the first light beam, which has an anti-glare function.

[0049] The low beam module 200 includes a second light source 210 and a second optical unit 220. The second light source 210 emits a second light beam in response to a low beam control command. The second optical unit 220 receives the second light beam and causes the second light beam to be emitted from the low beam area 302 of the outer lens 300 as a low beam beam to realize the low beam lighting function. Figure 4 That is, the second optical unit 220 and the low beam area 302 of the outer lens 300 transmit and shape the second light beam so that the second light beam is emitted in a low beam pattern, thereby realizing the low beam lighting function. It should be noted that the headlight module can also project a high beam and a low beam based on a high beam control instruction and a low beam control instruction, such as Figure 5 shown.

[0050] As can be seen from the above, this headlight module can achieve both anti-glare high-beam lighting and low-beam lighting functions. Compared with related technologies, it integrates low-beam lighting function on top of anti-glare high-beam lighting function, which is conducive to the development of multi-functional integration of headlights.

[0051] The outer lens 300 of the headlight module also has a high-beam region 301 and a low-beam region 302. This means that the high-beam module 100 and the low-beam module 200 share the same outer lens 300, resulting in a simple structure, a small number of optical components, and a compact size. Furthermore, the high-beam region 301 of the outer lens 300, which corresponds to the high-beam beam, serves as a focal lens, while the low-beam region 302, which corresponds to the high-beam beam, serves as a focal lens. This allows for more efficient projection of glare-free high and low-beam beams.

[0052] It should be noted that, for the vehicle lamp module, the first light source 110 and the second light source 210 are two separate light sources with different transmission light paths. Therefore, the first light source 110 and the second light source 210 can be arranged on different planes, thereby better dissipating the heat of the light source and preventing the loss of thermally induced light efficiency of the known light source.

[0053] Based on the above embodiments, in one embodiment of the present application, Figure 6 As shown, the first optical unit 120 includes a first inner lens 121, which includes a first total reflection surface 1211, a second total reflection surface 1212, a first light incident surface 1213, and a first light exiting surface 1214. Specifically, the first total reflection surface 1211 and the second total reflection surface 1212 are opposite to each other, the first light incident surface 1213 and the first light exiting surface 1214 are opposite to each other, and the first light incident surface 1213 and the first light exiting surface 1214 are located between the first total reflection surface 1211 and the second total reflection surface 1212. The first light incident surface 1213 is located on the light exiting side of the first light source 110.

[0054] The first light source 110 is located at the focus of the first total reflection surface 1211, and the focus of the high beam area 301 of the outer lens 300 is located on the second total reflection surface 1212. Specifically, the first light beam emitted by the first light source 110 enters the first inner lens 121 through the first light incident surface 1213, and then is reflected by the first total reflection surface 1211 and the second total reflection surface 1212 in sequence, and is emitted from the high beam area 301 of the outer lens 300 as a high beam. It should be noted that, as Figure 7 As shown in a and b, the first light beam is irradiated on the first total reflection surface 1211. The area closer to the first light source 110 forms a high beam with higher brightness, and the area farther away from the first light source 110 forms a high beam with gradually lower brightness.

[0055] When the focal length of the first total reflection surface 1211 is a first focal length, the high beam corresponds to the first high beam. When the focal length of the first total reflection surface 1211 is a second focal length, the high beam corresponds to the second high beam. If the first focal length is less than the second focal length, the light intensity of the first high beam is greater than the light intensity of the second high beam. Based on this, it can be seen that when the first light source 110 is located at the focal point of the first total reflection surface 1211, the focal length of the first total reflection surface 1211 can affect the light intensity of the high beam. Therefore, when designing the vehicle light module, the focal length of the first total reflection surface 1211 can be adjusted according to the actual high beam intensity requirements, or a first total reflection surface 1211 with an appropriate focal length can be selected to design a vehicle light module that meets the requirements.

[0056] When the focus of the high-beam region 301 of the outer lens 300 is located in the first area 12121 of the second total reflection surface 1212, the high-beam beam corresponds to the third high-beam beam. When the focus of the high-beam region 301 of the outer lens 300 is located in the second area 12122 of the second total reflection surface 1212, the high-beam beam corresponds to the fourth high-beam beam. If the first area 12121 is the area of ​​the second total reflection surface 1212 that is close to the first light source 110, and the second area 12122 is the area of ​​the second total reflection surface 1212 that is far from the first light source 110, then the light pattern area of ​​the third high-beam beam is smaller than the light pattern area of ​​the fourth high-beam beam. Based on this, it can be seen that the focus of the high-beam region 301 of the outer lens 300 is located on the second total reflection surface 1212. When designing the vehicle light module, the position of the focus of the high-beam region 301 of the outer lens 300 on the second total reflection surface 1212 can be adjusted according to the size of the high-beam beam's light pattern, thereby designing a vehicle light module that meets the requirements.

[0057] Based on the above embodiments, in one embodiment of the present application, Figure 6 As shown, the first light source 110 and the first optical unit 120 are arranged along the first direction, the second total reflection surface 1212 is a plane, and the plane where the second total reflection surface 1212 is located has a preset angle a with the first direction.

[0058] Specifically, the value of the preset angle a can be 45°. However, this application does not limit this. In other embodiments of this application, the value of the preset angle a can also be 44° or 46°, etc., depending on the specific situation.

[0059] Based on the aforementioned embodiment, in one embodiment of the present application, the first light-emitting surface 1214 is a plane or a curved surface. When the first light-emitting surface 1214 is a plane, the high-beam beam corresponds to the fifth high-beam beam. When the first light-emitting surface 1214 is a curved surface, the first light-emitting surface 1214 can diverge the first light beam, and the high-beam beam corresponds to the sixth high-beam beam. The light pattern area of ​​the sixth high-beam beam is larger than the light pattern area of ​​the sixth high-beam beam. Based on this, it can be seen that the curvature of the first light-emitting surface 1214 can also affect the size of the high-beam beam pattern. Therefore, when designing the vehicle light module, the curvature of the first light-emitting surface 1214 can be adjusted according to the size of the high-beam beam pattern, thereby designing a vehicle light module that meets the requirements.

[0060] From the above, it can be seen that when designing the headlight module, the intensity and light pattern of the high beam can be controlled by adjusting the focal length of the first total reflection surface 1211, adjusting the position of the focus of the high beam area 301 of the outer lens 300 on the second total reflection surface 1212, and adjusting the curvature of the first light-emitting surface 1214, thereby designing a headlight module that meets the requirements. The headlight module is suitable for the design of various headlight modules and is more practical.

[0061] Based on the above embodiments, in one embodiment of the present application, Figure 8 As shown, the first light source 110 includes a plurality of sub-light sources 111 arranged along the second direction. The first light source 110 controls at least part of the plurality of sub-light sources 111 to emit a first light beam in response to a high beam control instruction. Specifically, the sub-light sources 111 that will produce a glare effect are turned off, and the sub-light sources 111 that will not produce a glare effect are turned on, so that the first light beam has an anti-glare function. The second direction is parallel to the extension direction of the first light incident surface 1213, and the extension direction of the first light emitting surface 1214 is an extension direction that can make the plurality of sub-light sources 111 all located at the focus of the first total reflection surface 1211. Specifically, in one embodiment of the present application, as Figure 9 As shown, the multiple sub-light sources include 16 sub-light sources, specifically 16 small-sized single-core LEDs, with 10 on one side and 6 on the other side, with the focus of the high-beam area 301 of the outer lens 300 as the center line. However, this application is not limited to this. In other embodiments of the application, there may be 20 small-sized single-core LEDs, 10 on one side and 10 on the other side, etc., depending on the specific situation.

[0062] The first light-entering surface 1213 has a plurality of focusing teeth 12131 arranged along the second direction. Each of the focusing teeth 12131 corresponds one-to-one with each of the sub-light sources 111 to focus the first light beams emitted by the corresponding sub-light sources 111, preventing light crosstalk between adjacent sub-light sources 111 and ensuring a high-beam lighting effect. The focusing teeth 12131 extend parallel to the third direction, which is parallel to the plane of the first light-entering surface 1213 and perpendicular to the second direction.

[0063] As can be seen from the above, the first light incident surface 1213 of the headlight module has a plurality of focusing teeth 12131 for converging the first light beam. After the focusing teeth 12131 converge the first light beam, the light is reflected by the first total reflection surface 1211 and the second total reflection surface 1212, and then emitted from the high beam area 301 of the outer lens 300 through the first light exit surface 1214. Compared with the existing technology, the length of the focusing teeth is effectively shortened, the mechanical strength of the focusing teeth is improved, and the processing difficulty is reduced.

[0064] Specifically, in one embodiment of the present application, Figure 10 As shown, the depth L1 of the focusing teeth 12131 can be 2-3 mm, the width L2 can be 1.2-1.5 mm, the length L3 can be 5-10 mm, and the center distance L4 between two adjacent focusing teeth 12131 can be 1.5-2 mm. However, this application does not limit this, and it depends on the specific situation.

[0065] Based on the above embodiments, in one embodiment of the present application, Figure 11As shown, the second optical unit 220 comprises a second inner lens 221, which comprises a third total reflection surface 2211, a second light-in surface 2212 and a second light-out surface 2213. Specifically, the third total reflection surface 2211 is located between the second light-in surface 2212 and the second light-out surface 2213, and the second light-in surface 2212 is opposite to the second light-out surface 2213, and the second light-in surface 2212 is located at the light-out side of the second light source.

[0066] The second light source 210 is located at the focal point of the third total reflection surface 2211, and the second light beam enters the second inner lens 221 through the second light-in surface 2212, and then is reflected by the third total reflection surface 2211 and exits from the second light-out surface 2213 in the low beam light beam, that is, the second optical unit 220 and the low beam region 302 of the outer lens 300 transmit and shape the second light beam, so that the second light beam exits in the low beam light type to realize the low beam illumination function.

[0067] From the above, in the vehicle lamp module, the second light source 210 is located at the focal point of the third total reflection surface 2211, so that the second light beam emitted by the second light source can be reflected by the third total reflection surface to form a low beam light beam with high efficiency, thereby ensuring the light efficiency of low beam illumination.

[0068] Based on the foregoing embodiment, in an embodiment of the present application, as shown in the figure, Figure 12 The second light-out surface 2213 is an arc surface, and the focal point of the low beam light beam is located at the focal point of the low beam region 302 of the outer lens 300. That is, after the second light beam exits through the second light-out surface 2213, before being projected by the outer lens 300, the intersection point of the reverse extension line of the second light beam coincides with the focal point of the low beam region 302 of the outer lens 300 at this time, which is equivalent to that the second light beam projected by the low beam region 302 of the outer lens 300 comes from its focal point, so that the second light beam can be projected by the low beam region 302 of the outer lens 300 as much as possible, which helps to ensure the light efficiency of low beam illumination. It should be noted that the arc surface of the second light-out surface 2213 can also have a converging effect on the second light beam, further ensuring that the second light beam can be projected by the low beam region 302 of the outer lens 300 as much as possible, which helps to ensure the light efficiency of low beam illumination.

[0069] Based on the foregoing embodiment, in an embodiment of the present application, as shown in the figure, Figure 13 The region of the third total reflection surface 2211 close to the second light source 210 has a cutoff line structure 22111, and the second light beam can form a low beam light type through the cutoff line structure 22111, thereby helping to form a low beam light beam. It should be noted that the cutoff line structure 22111 shown in the figure is only a schematic representation of the cutoff line structure 22111, and is not a limitation on the specific structure or shape of the cutoff line structure 22111.

[0070] Based on the foregoing embodiments, in one embodiment of the present application, as shown in FIG. 3, the light-emitting side of the high beam region 301 of the outer lens 300 has micro patterns. In another embodiment of the present application, the light-emitting side of the high beam region 301 of the outer lens 300 has micro patterns, and the light-emitting side of the low beam region 302 of the outer lens 300 also has micro patterns. Figure 14

[0071] Correspondingly, the present application also provides a vehicle lamp, which comprises the vehicle lamp module of any one of the foregoing embodiments.

[0072] In summary, the present application provides a vehicle lamp module and a vehicle lamp. The vehicle lamp module comprises a high beam module, a low beam module, an outer lens, and a light shield plate. The outer lens comprises a high beam region and a low beam region. The high beam region is a focal point lens, and the low beam region is a focal line lens. The light shield plate is located between the high beam module and the low beam module. The high beam module comprises a first light source and a first optical unit. At least part of the light-emitting region of the first light source emits a first light beam in response to a high beam control instruction. The first light beam has an anti-dazzling function. The first optical unit receives the first light beam and causes the first light beam to be emitted from the high beam region of the outer lens as a high beam light beam to achieve an anti-dazzling high beam illumination function. The low beam module comprises a second light source and a second optical unit. The second light source emits a second light beam in response to a low beam control instruction. The second optical unit receives the second light beam and causes the second light beam to be emitted from the low beam region of the outer lens as a low beam light beam to achieve a low beam illumination function. Thus, on the basis of having an anti-dazzling high beam illumination function, the low beam illumination function is integrated, which is conducive to the development of multifunctional integration of vehicle lamps.

[0073] In addition, the high beam module and the low beam module share the same outer lens, so that the vehicle lamp module has a simple structure, a small number of optical elements, and a small size.
