[0028] 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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] In related technologies, H4 LED bi-xenon small lens headlights typically use a design scheme of a single reflector cup with dual light sources or a single reflector cup with direct dual light sources. These headlights are not bright enough in low beam mode, which affects driving comfort and safety.

[0030] In view of this, embodiments of this application propose a vehicle lighting module and a vehicle to effectively solve the aforementioned problems.

[0031] See Figures 1 to 4 As shown, an embodiment of the first aspect of this application discloses a vehicle headlight module that, in low beam mode, supplements the low beam with a portion of the light emitted by the high beam source 110 to improve the headlight illumination in low beam mode.

[0032] The following will combine Figures 1 to 4 The vehicle lighting module disclosed in the embodiments of this application will be explained and described in detail.

[0033] like Figures 1 to 4 As shown, the vehicle headlight module of the first aspect of this application includes a high beam component, a low beam component, and a light shield component.

[0034] Specifically, the high beam assembly includes a high beam light source 110 and a first reflector 120, with the first reflector 120 cooperating with the high beam light source 110; the low beam assembly includes a low beam light source 210 and a second reflector 220, with the low beam light source 210 located in front of the high beam light source 110 and its mounting plane lower than that of the high beam light source 110, and the second reflector 220 cooperating with the low beam light source 210; the light shield assembly includes a light shield 310, which is used to at least partially block the light emitted by the high beam light source 110, so that the headlight module switches from high beam mode to low beam mode.

[0035] It is understandable that when the light shield 310 blocks the light emitted by the high beam source 110, the light shield 310 is located in front of the opening of the first reflector 120. In order to allow the light emitted by the high beam source 110 to partially supplement the low beam, the light shield 310 needs to be positioned above the opening of the first reflector 120 to block the upper part of the first reflector 120 and prevent the light emitted by the high beam source 110 from escaping from the upper part of the first reflector 120; at this time, the light emitted by the high beam source 110 can be emitted from the lower side of the light shield 310 to supplement the low beam.

[0036] In the vehicle headlight module provided in this embodiment, when the headlight module is in low beam mode, both the high beam light source 110 and the low beam light source 210 remain constantly lit. The light shield 310 moves to the opening of the first reflector 120 to block the light emitted from the high beam light source 110 and emitted from the upper part of the opening of the first reflector 120. Part of the light emitted from the high beam light source 110 can then be emitted from the lower side of the light shield 310. At this time, the light emitted from the low beam light source 210 is emitted through the second reflector and, together with the light emitted from the lower side of the light shield 310, serves as the illumination light for the low beam mode. This effectively improves the illuminance in low beam mode, enhancing driving comfort and safety.

[0037] In some embodiments of this application, the vertical height of the sunshade 310 is less than the vertical height of the opening of the first reflector 120. That is, the sunshade 310 cannot completely block the opening of the first reflector 120. Thus, when the sunshade 310 moves to the front of and above the opening of the first reflector 120, some light emitted from the high beam source 110 can be emitted from the bottom of the sunshade 310. Simultaneously, light emitted from the low beam source 210 is reflected by the second reflector 220 and emitted, then overlaps with some light emitted from the lower side of the sunshade 310. This improves the illumination of the low beam mode, enhancing driving comfort and safety.

[0038] It is worth noting that in some other embodiments, the height of the light-shielding plate 310 in the vertical direction may also be greater than the height of the opening of the first reflector cup 120. In this case, it is necessary to control the light-shielding plate 310 to partially block the opening of the first reflector cup 120 so that some of the light emitted by the high beam light source 110 can be emitted from the bottom of the light-shielding plate 310.

[0039] It should be noted that by changing the area of ​​the opening of the first reflector cup 120 blocked by the light shield 310, the luminous flux supplemented to the low beam by the high beam light source 110 can be changed, thereby changing the illuminance in the low beam mode.

[0040] In some embodiments of this application, the light-shielding plate 310 has a first working position and a second working position. When the light-shielding plate 310 is in the first working position, it is located directly in front of the second reflector 220; when the light-shielding plate 310 is in the second working position, it is located in front of the first reflector 120 and above the opening of the first reflector 120.

[0041] In one possible implementation, both the high beam light source 110 and the low beam light source 210 remain constantly lit in both low beam and high beam modes. Specifically, when switching from low beam mode to high beam mode, the light shield 310 moves from the second working position to the first working position, i.e., the light shield 310 is located in front of the second reflector 220, and the light shield 310 does not block the light emitted by the high beam light source 110; when switching from high beam mode to low beam mode, the light shield 310 moves from the first working position to the second working position, i.e., the light shield 310 is located in front of the first reflector 120, and the light shield 310 is located above the opening of the first reflector 120, so the light emitted by the high beam light source 110 can be emitted from below the light shield 310 and projected onto the front of the headlight module together with the light emitted by the low beam light source 210.

[0042] In some embodiments of this application, see Figure 2 and Figure 4 The light-shielding assembly includes a drive unit 320, which is used to drive the light-shielding plate 310 to switch between a first working position and a second working position.

[0043] In one possible implementation, the driving member 320 includes a magnetic rod and a driving coil sleeved around the outer periphery of the magnetic rod. The magnetic rod is connected to the light-shielding plate 310, and the driving coil drives the magnetic rod to move along its own axis when energized. The axis of the magnetic rod is parallel to the vertical direction. By moving along its own axis, the magnetic rod can move the light-shielding plate 310 from a first working position to a second working position, or vice versa.

[0044] Further, see Figure 2 The light-shielding assembly includes a base 330, a stop portion 340, and a limiting member 350. A drive coil is mounted on the base 330, the stop portion 340 is connected to the base 330, and the limiting member 350 is connected to a magnetic rod. The stop portion 340 is used to stop the limiting member 350. In this embodiment, the stop portion 340 is provided on the base 330 to stop the limiting member 350, preventing the magnetic rod from detaching from the drive coil.

[0045] In some embodiments of this application, see Figure 2As shown, the second reflector 220 has a top plane 221, which is not higher than the bottom surface 121 of the first reflector 120. Thus, during operation, the second reflector 220 will not block the light emitted by the high beam source 110.

[0046] It is worth understanding that the top plane 221 not being higher than the bottom surface 121 of the first reflector cup 120 means that the top plane 221 is flush with or lower than the bottom surface 121.

[0047] In some embodiments of this application, the headlight module further includes a lens assembly 400, which is disposed in front of the low beam assembly.

[0048] Traditional H4 LED bi-xenon projector headlights have the high beam off when the low beam is on, meaning the high beam cannot compensate for the low beam.

[0049] In the embodiment of the application, both the high beam and low beam sources are constantly on in low beam mode. The switching between high beam and low beam modes is achieved by changing the position of the sun visor. In low beam mode, the sun visor blocks the light emitted by the high beam source to achieve low beam. At the same time, the high beam source remains constantly on, but the upper part of the light is blocked, while the lower part of the light effectively complements the low beam, thus achieving a bright effect in both high beam and low beam modes, improving driving comfort and driving safety.

[0050] The second aspect of this application discloses a vehicle including the aforementioned headlight module, which has all the technical effects of the aforementioned headlight module, and will not be repeated here.

[0051] It is worth understanding that the vehicle in the embodiments of this application can be an automobile or other forms of transportation, and is not limited here.
