[0037] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in 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.

[0038] With the advancement of automotive lighting technology, headlights capable of dynamic lighting effects are becoming increasingly popular. Traditional headlights that create dynamic lighting effects primarily achieve this through the flickering of array-arranged LEDs or by mechanically moving decorative frames to obscure or expose the light-emitting structure. However, headlights that create dynamic effects through array-arranged LEDs can only produce static animation effects. Meanwhile, headlights that use mechanical movement of decorative frames to obscure or expose the light-emitting structure rely solely on the different ways the decorative frames obscure the light-emitting structure, resulting in poor lighting effects.

[0039] For this reason, Figure 1 As shown, an embodiment of the present application discloses a lighting device, including a light-emitting module 100 and a display module 200, and can realize a combination of multiple position forms of the light-emitting module 100 and the display module 200 through mechanical movement, thereby realizing a variety of dynamic lighting effects of the car lights, making the car lights more diverse in shape and more layered in appearance, increasing the user experience, and at the same time making the entire car lights more mechanical and technological.

[0040] The following will be combined Figures 1 to 8The lighting device disclosed in the embodiments of the present application is specifically explained and illustrated.

[0041] Among them, Figure 1 and Figure 2 As shown, the light-emitting modules 100 may include at least two, and each light-emitting module 100 is movably arranged so that each light-emitting module 100 can change its position and form through mechanical movement. At the same time, the display modules 200 may include at least two, and the display modules 200 are blocked in front of the light-emitting modules 100. At least one display module 200 is movably arranged so that the display module 200 can change its position and form through mechanical movement, thereby achieving the effect of blocking the light-emitting module 100 or allowing the light path of the light-emitting module 100 to pass through. Furthermore, the light-emitting modules 100 and the display modules 200 can be combined in various positions and forms through mechanical movement, thereby achieving a variety of dynamic lighting effects for the headlights, making the headlights more diverse in shape and layered in appearance, enhancing the user experience, and making the entire headlights more mechanical and technological.

[0042] In some embodiments, as Figure 1 As shown, the display module 200 can be three. For ease of understanding, the three display modules 200 are defined as a first display module 201, a second display module 202, and a third display module 203. The second display module 202 and the third display module 203 are located on the upper and lower sides of the first display module 201, respectively. Figure 8 As shown, the first display module 201 may include a first display module 2011 and a link mechanism 2012 connected to the first display module 2011. The link mechanism 2012 may drive the first display module 2011 to move, so as to achieve the effect of the first display module 2011 shielding the light emitting module 100 or allowing the light path of the light emitting module 100 to pass through. Figure 5 As shown, the second display module 202 may include a second display module 2021 and a first sliding mechanism 2022 connected to the second display module 2021. The first sliding mechanism 2022 may drive the second display module 2021 to move, so as to achieve the effect of the second display module 2021 shielding the light emitting module 100 or allowing the light path of the light emitting module 100 to pass through. Figure 5 As shown, the third display module 203 may include a third display module 2031 and a second sliding mechanism 2032 connected to the third display module 2031. The second sliding mechanism 2032 can drive the third display module 2031 to move, so as to achieve the effect of the third display module 2031 blocking the light-emitting module 100 or allowing the light path of the light-emitting module 100 to pass through.

[0043] In some embodiments, as Figures 6 to 8As shown, the link mechanism 2012 may include a first link 2013, a second link 2014, and a first driving member 2015. The first display module 2011 may be a strip-shaped structure, and the first display module 2011 has upper and lower sides that are oppositely disposed, and the two sides of the first display module 2011 are hinged to the first link 2013 and the second link 2014, respectively. The first link 2013 is hinged to a first fixed end 2016, and the second link 2014 is provided with an inflection point 2017, the inflection point 2017 of the second link 2014 being hinged to a second fixed end 2018. The first driving member 2015 is hinged to the second link 2014, so that the first display module 2011 can be driven to move by the first driving member 2015, so that the first display module 2011 is located behind the third display module 2031, thereby realizing the switching of the first display module 2011 between different positions and configurations. At this time, each light emitting module 100 can emit light through the initial position of the first display module 2011 to achieve a lighting effect.

[0044] In some embodiments, as Figures 3 to 5 As shown, the first sliding mechanism 2022 may include a first sliding assembly and a second driving member 2023. The first sliding assembly may include a first sliding track 2024 and a first pin 2025 that slidably engages with the first sliding track 2024. The second display module 2021 may have a strip-shaped structure and have upper and lower sides that are oppositely disposed. A first pin 2025 is disposed on both sides of the second display module 2021. The first pin 2025 on either side of the second display module 2021 is connected to the second driving member 2023, thereby enabling the second driving member 2023 to drive the second display module 2021 to move along the first sliding track 2024, allowing the second display module 2021 to switch between positions in front of and above the light-emitting module 100, thereby achieving the effect of shielding the light-emitting module 100 or allowing the light path of the light-emitting module 100 to pass through. When the second display module 2021 is above the light-emitting module 100, part of the light-emitting module 100 can emit light from the initial position of the second display module 2021, thereby achieving a lighting effect. It should be noted that in order to avoid the light-emitting module 100, the first sliding track 2024 can be a curved track to avoid interfering with the installation and mechanical movement of the light-emitting module 100.

[0045] In some embodiments, as Figures 3 to 5As shown, the second sliding mechanism 2032 may include a second sliding assembly and a third driving member 2033 . Among them, the second sliding assembly may include a second sliding rail 2034, a third sliding rail 2035 and a second pin 2036, the third display module 2031 may adopt a strip structure, and the third display module 2031 has an upper and lower sides relatively set, and a second pin 2036 is set on both sides of the third display module 2031, and the two second pins 2036 are respectively slidably matched with the second sliding rail 2034 and the third sliding rail 2035, and the second pin 2036 on any side of the third display module 2031 is connected to the third driving member 2033, so that the third driving member 2033 can drive the third display module 2031 to move along the second sliding rail 2034 and the third sliding rail 2035, so that the third display module 2031 switches between the positions in front of and below the light-emitting module 100, thereby achieving the effect of blocking the light-emitting module 100 or allowing the light path of the light-emitting module 100 to pass through. When the third display module 2031 is below the light emitting module 100, part of the light emitting module 100 can emit light from the initial position of the third display module 2031 to achieve a lighting effect. It should be noted that the second sliding track 2034 and the third sliding track 2035 can be arranged to intersect or be arranged separately. Figure 5 As shown, when the second sliding track 2034 and the third sliding track 2035 are arranged to intersect, the second sliding track 2034 can adopt a straight track, and the third sliding track 2035 can adopt an arc track, and one end of the second sliding track 2034 is arranged tangent to the third sliding track 2035, so that the second pin shaft 2036 on both sides of the third display module 2031 can be driven by the third driving member 2033 to move along the second sliding track 2034 and the third sliding track 2035, so that the third display module 2031 can switch between the front and bottom positions of the light-emitting module 100.

[0046] Of course, the first display module 201, the second display module 202 and the third display module 203 can also be three, four, five or more respectively, and each first display module 201, the second display module 202 and the third display module 203 are arranged at intervals to avoid mutual interference in the mechanical movement of the first display module 201, the second display module 202 and the third display module 203.

[0047] In the above embodiment, the first display module 2011, the second display module 2021 and the third display module 2031 can be combined with signal lights or display screens to realize the vehicle's welcome interaction function. Of course, daytime running lights, turn signals and other functions can also be set on the first display module 2011, the second display module 2021 and the third display module 2031.

[0048] In some embodiments, as Figure 8 As shown, the light-emitting module 100 may include a light-emitting module 101 and a lifting mechanism 102 connected to the light-emitting module 101. The lifting mechanism 102 can drive the light-emitting module 101 to move so that the light-emitting module 101 switches between different positions. The lifting mechanism 102 may include a scissors-bracing bracket 1021 and a fourth driving member 1022. The scissors-bracing bracket 1021 has two oppositely arranged ends. For ease of understanding, the two ends of the scissors-bracing bracket 1021 are defined as a first end and a second end, respectively. The first end of the scissors-bracing bracket 1021 is hinged to the light-emitting module 101, and the second end of the scissors-bracing bracket 1021 is a fixed end. It can be connected to any one of the hinge shafts of the second end of the scissors-bracing bracket 1021 through the fourth driving member 1022, so that the fourth driving member 1022 can drive the first end of the scissors-bracing bracket 1021 to move in a direction away from or close to the second end of the scissors-bracing bracket 1021, thereby realizing the switching of the light-emitting module 101 between different positions, thereby realizing different dynamic lighting effects. Of course, the fourth driving member 1022 may also be connected to the first end of the scissors support bracket 1021 , thereby driving the first end of the scissors support bracket 1021 to move in a direction away from or close to the second end of the scissors support bracket 1021 .

[0049] In order to enable the light emitting module 101 to move up and down under the drive of the scissors support bracket 1021, Figure 8 As shown, in some embodiments, the first end of the scissor brace bracket 1021 can be hinged to the light-emitting module 101 via two hinge shafts 1023, and a slide groove 1024 is provided on the light-emitting module 101, so that either of the two hinge shafts 1023 is located within the slide groove 1024. When the fourth driving member 1022 drives the first end of the scissor brace bracket 1021 to move away from or toward the second end of the scissor brace bracket 1021, the hinge shaft 1023 can slide along the slide groove 1024, thereby achieving the lifting and lowering movement of the light-emitting module 101 under the drive of the scissor brace bracket 1021.

[0050] In the above embodiment, the light emitting module 101 may be a reflective bowl or an illumination module, etc., and any structure that can emit light is acceptable, and this document does not limit this.

[0051] Of course, three, four, five, or more light-emitting modules 101 may be used, and each light-emitting module 100 may be located on the same plane. To prevent mechanical interference between the light-emitting modules 101, the light-emitting modules 100 may be spaced apart and moved in an up-and-down staggered pattern, thereby enhancing the vehicle's sense of technology and layering, and improving the lighting effect.

[0052] In addition, in the above embodiment, the first driving member 2015, the second driving member 2023, the third driving member 2033 and the fourth driving member 1022 can adopt screw motors, telescopic cylinders, etc., which are not limited herein.

[0053] It should be noted that the mechanical movement of the light emitting module 100 and the display module 200 is not limited to the lifting mechanism 102, the connecting rod mechanism 2012 and the sliding mechanism used in the above embodiment, and other mechanical movement methods may also be used, which is not limited herein.
