Description

Technical Field

[0001] This application relates to the field of automotive lighting technology, and in particular to an automotive lighting module and a vehicle. Background Technology

[0002] As an important component of vehicle safety and personalized design, vehicle lights are facing increasingly higher functional and technical requirements. Traditional vehicle lights mainly use incandescent bulbs or LEDs (light-emitting diodes) as light sources, with limited functions, only able to transmit simple signal information, such as braking and steering, by turning on, off, or flashing.

[0003] With the rapid development of the automotive industry, headlights capable of displaying patterns have appeared on the market. These headlights are made of OLED (Organic Light-Emitting Diode) and can display patterns on curved headlight surfaces. However, bending OLEDs can only create developable surfaces, while the outer surface of most headlights is non-developable. This makes it difficult to adapt OLEDs and hinders the improvement of headlight versatility. Utility Model Content

[0004] In view of this, this application aims to propose a vehicle lighting module to improve the versatility of vehicle lights.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A vehicle lighting module includes a mounting section, and a light source and a light guide module disposed on the mounting section; The light guide module includes a plurality of light guides that can move relative to the mounting portion, and a driving portion that connects the light guides and the mounting portion, with each driving portion corresponding to each light guide. Each of the light guides is used to guide the light from the light source to the outside, and each of the driving units can drive the corresponding light guide to move, enabling the light guide to switch between a first position and a second position, thereby switching the light guide and the light source between a coupled state and a decoupled state.

[0006] Furthermore, the mounting part is provided with a plurality of guide holes extending along a preset direction, each guide hole corresponding to the light guide part, and each driving part can drive the light guide part to move within the corresponding guide hole.

[0007] Furthermore, each of the guide holes has a light inlet hole on its wall. The light inlet hole is located on the light transmission path from the light source to the light guide. The light emitted by the light source enters the corresponding guide hole through each of the light inlet holes. Each of the light guides has a light-shielding part at one end. When each light guide moves within the guide hole, it can drive the light-shielding part to move between a first position that exposes the light inlet hole and a second position that covers the light inlet hole.

[0008] Furthermore, the light source includes a light strip disposed on the mounting portion, and the light guide module further includes a light guide plate coupled to the light strip; The light guide plate can guide the light emitted by the light strip into each of the guide holes.

[0009] Furthermore, the light guide plate has multiple insertion portions, each of which corresponds to a light inlet hole, and each insertion portion is inserted into the corresponding light inlet hole.

[0010] Furthermore, each of the guide holes has a diffuse reflection layer on its hole wall to reflect the light that shines on the hole wall into the light guide portion.

[0011] Furthermore, each of the light-shielding portions has a diffuse reflection layer on its sidewall facing the corresponding light guide portion, so as to reflect the light that shines on the sidewall of the light-shielding portion into the light guide portion.

[0012] Furthermore, the mounting portion has an extension portion extending along the preset direction, the extension portion being fitted to the inner wall of the lamp cover of the vehicle lamp; Each of the guide holes has an opening on the extension portion, and the lampshade covers the opening.

[0013] Furthermore, when each of the light guides is in the second position, it can fit against the inner wall of the headlight cover.

[0014] Furthermore, each of the driving units includes an electromagnet disposed on the mounting unit and a magnet disposed on the corresponding light guide unit. The electromagnet can drive the magnet to move the light guide unit.

[0015] Compared with related technologies, this application has the following advantages: (1) The vehicle light module described in this application drives the light guide to move by setting a driving part, so that the light guide guide guides light at the first position and does not guide light at the second position. This allows each light guide to be used as a pixel to create changes in brightness and darkness to display different patterns. Since each light guide is a pixel, the vehicle light module can be well adapted when used for non-developable curved surface vehicle lights, which is beneficial to improving the versatility of the vehicle light module. At the same time, the light guide guide method has a higher luminous intensity than the OLED method, which makes the pattern display clearer and is beneficial to improving the display effect.

[0016] (2) Multiple guide holes can guide the light guide, allowing the light guide to switch between the first and second positions along a predetermined trajectory, which helps to improve the movement stability of the light guide and thus improve the reliability of the vehicle lamp module.

[0017] (3) A light inlet hole is provided on the wall of the guide hole. The light from the light source enters the guide hole through the light inlet hole. With the help of the light-blocking part, the light can be blocked by the light-blocking part. The structure is simple and reliable, and it is not easy to leak light when the light-blocking part covers the light inlet hole.

[0018] (4) Setting a single light strip in conjunction with a light guide plate can provide light to multiple guide holes, which can reduce the number of redundant light sources, improve the utilization rate of light sources, and reduce energy consumption.

[0019] (5) The light guide plate has multiple insertion parts, which can be connected to the mounting part by plugging in. The installation is convenient, and the insertion parts enter the light inlet hole, so the path of light entering the guide hole is shorter, which helps to reduce light loss.

[0020] (6) A diffuse reflection layer is provided on the wall of the guide hole, which makes it difficult for the guide hole wall to absorb light and allows more light to be concentrated in the light guide part; a diffuse reflection layer is provided on the side wall of the light shield facing the light guide part, which makes it difficult for the light shield to absorb light and allows more light to be concentrated in the light guide part.

[0021] (7) Extending the mounting part in the preset direction and fitting it to the lamp cover allows the guide hole to pass directly through the lamp cover. The light from the light guide part can only be emitted outward from the lamp cover from the opening of the guide hole, which helps to reduce stray light and improve the clarity of the vehicle light pattern display.

[0022] (8) The light guide is attached to the lamp cover at the second position. The lamp cover can limit the light guide. At the same time, the light guide is attached to the lamp cover. From the outside, it is not easy to have uneven or shadowy visual effects, which is conducive to improving the appearance quality of the car lights.

[0023] (9) The drive unit adopts a combination of electromagnet and magnet. When the electromagnet is energized, it generates a magnetic field, which attracts or repels the magnet on the light guide, thereby driving the light guide to move. The magnetic force of the electromagnet and the magnet has a fast response speed and high working stability, which is beneficial to improving the life of the vehicle lamp module.

[0024] Another object of this application is to provide a vehicle that includes the aforementioned headlight module.

[0025] The vehicle described in this application, by setting the aforementioned headlight module, can also achieve pixelated pattern display and dynamic change functions when the selected headlight is a non-developable curved surface lamp cover. It can display diverse patterns and symbols through the headlights, realize richer vehicle interaction functions, make the vehicle more differentiated in appearance and function, and improve the vehicle's quality of use and product competitiveness.

[0027] To make the technical solution and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" 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 or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0031] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0032] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0033] An embodiment of the first aspect of this application provides a vehicle lighting module to improve the versatility of vehicle lights.

[0034] In related technologies, vehicle lights, as an important component of vehicle safety and personalized design, are facing increasingly higher functional and technical requirements. Traditional vehicle lights mainly use incandescent or LED light sources, with limited functions, only able to transmit simple signal information, such as braking and steering, by turning on, off, or flashing.

[0035] With the rapid development of the automotive industry, headlights capable of displaying patterns have appeared on the market. These headlights are made of OLED (Organic Light-Emitting Diode). OLED headlights are superior to traditional headlights due to their self-illuminating, wide viewing angle, and high contrast characteristics, making them more in line with modern aesthetics. Moreover, OLED headlights can display patterns on their own curved surfaces, becoming a new highlight of vehicle products.

[0036] This OLED headlight breaks the limitations of traditional headlights' single light emission mode. Through dynamic programming, it can create diverse pattern displays, such as vehicle brand logos, welcome animations, dynamic turn signal patterns, and fault warning symbols, enriching the headlight's functionality. The highly customizable pattern display modes also enhance vehicle recognition, making the vehicle more technologically advanced.

[0037] However, bending OLEDs can only create developable surfaces, which are curved surfaces that can be unfolded into a plane without deformation by preserving their length. These surfaces are necessarily ruled surfaces in three-dimensional space, including planes, cylinders, cones, and tangent surfaces of curves. In actual production, most vehicles use non-developable surfaces for their headlight covers to achieve a streamlined shape. OLEDs cannot easily form corresponding non-developable surfaces to fit these covers, hindering the improvement of headlight versatility.

[0038] In view of this, in order to overcome the shortcomings of the related technology, the vehicle lamp assembly of this embodiment combines... Figures 1 to 4 As shown, the overall design includes a mounting part 1, and a light source 2 and a light guide module 3 disposed on the mounting part 1.

[0039] The light guide module 3 includes multiple light guide sections 301 that are movable relative to the mounting section 1, and a driving section 302 connecting the light guide sections 301 and the mounting section 1. Each driving section 302 corresponds to one of the light guide sections 301. Each light guide section 301 is used to guide the light from the light source 2 to the outside. Each driving section 302 can drive the corresponding light guide section 301 to move, enabling the light guide section 301 to switch between a first position and a second position, thereby switching the light guide section 301 and the light source 2 between a coupled state and a decoupled state.

[0040] Therefore, by setting the driving unit 302 to drive the light guide unit 301 to move, so that the light guide unit 301 guides light at the first position and does not guide light at the second position, each light guide unit 301 can be used as a pixel to create changes in brightness and darkness to display different patterns. Since each light guide unit 301 is a pixel, the car light module can also be well adapted when used for non-developable curved surface car lights, which is conducive to improving the versatility of the car light module.

[0041] Based on the above overview, specifically, the coupling between the light guide 301 and the light source 2 means that the light emitted from the light source 2 can enter the light guide 301, while the decoupling means that the light emitted from the light source 2 cannot enter the light guide 301. Each light guide 301 is a pixel in the display of the vehicle headlight pattern, and the arrangement of the light guides 301 can be designed according to the actual shape of the vehicle headlight. In a single vehicle headlight, only one headlight module can be arranged; in this case, all light guides 301 need to be installed on the mounting part 1. Alternatively, multiple headlight modules can be arranged in a single headlight, each responsible for a display area, with multiple headlight modules working together to display the vehicle headlight pattern.

[0042] The structure of the vehicle headlight may include, for example, a backplate housing 5 and a lamp cover 4. The headlight module is installed between the backplate housing 5 and the lamp cover 4. The backplate housing 5 is mounted on the vehicle body. The headlight module is connected to the vehicle system via wires, and the vehicle system controls the lighting and extinguishing of the headlight module. The mounting part 1 can be installed on the backplate housing 5. The connection between the mounting part 1 and the backplate housing 5 can be by snap-fit, bolt connection, or adhesive bonding, as long as the mounting part 1 can be fixed to the backplate housing 5.

[0043] The vehicle light module of this embodiment can be used in any one or more of the headlights, taillights, and turn signals of a vehicle. It can also be used as a display screen on the vehicle body to display images and show the information that needs to be displayed. As long as multiple sets of vehicle light modules are arranged according to the requirements and matched with a light source 2 of appropriate brightness, it can be used.

[0044] Comparing the headlight module of this application embodiment with OLED headlights, OLED headlights are limited by their inherent characteristics, resulting in generally lower brightness. In contrast, this application employs a light guide 301, which, compared to the self-emissive nature of OLEDs, provides higher luminous intensity, leading to higher contrast in pattern display and improved display quality. Furthermore, OLEDs also suffer from weak structural strength and are easily damaged. This application, however, uses a light guide 301 in conjunction with the light source 2, resulting in strong mechanical stability, excellent impact resistance, and a longer lifespan for the headlights.

[0045] Furthermore, the manufacturing process of OLED curved screens is relatively complex, with high material and processing costs. In contrast, the materials used in this application are significantly cheaper than those for OLEDs, and the manufacturing process is simpler, making it easier to promote and use. Moreover, the organic layer of OLED displays is prone to aging, and the display effect deteriorates after a certain period of use, potentially requiring more frequent replacements. In contrast, the light-emitting structure arrangement in this embodiment makes the components less susceptible to aging.

[0046] Continue to combine Figures 1 to 4As shown, in some exemplary embodiments, the mounting part 1 is provided with a plurality of guide holes 101 extending in a preset direction, each guide hole 101 corresponding to a light guide part 301, and each driving part 302 can drive the light guide part 301 to move within the corresponding guide hole 101.

[0047] In this way, the guide hole 101 provides a fixed trajectory constraint for the movement of the light guide 301, making it less prone to deviation or shaking during movement. This ensures that the light guide 301 accurately reaches the first and second positions, thereby guaranteeing the reliability of the brightness switching of the corresponding individual pixels and reducing the risk of display pattern distortion and light leakage due to positional deviation of the light guide 301. During the assembly of the automotive headlight module, the light guide 301 can be directly inserted into the corresponding guide hole 101 to complete the initial assembly of the light guide 301.

[0048] The aforementioned preset direction can be understood as the direction corresponding to the shortest movement path when the light guide 301 moves between the first and second positions. The preset direction is a straight line, which helps to shorten the moving distance of the light guide 301, reduce the time required for the light guide 301 to move between the first and second positions, and accelerate the lighting and extinguishing response speed of the corresponding pixels. Since each guide hole 101 extends along the preset direction, it ensures a high degree of consistency in the light guiding direction of each light guide 301, resulting in a better display effect for the vehicle headlight pattern.

[0049] Understandably, the shape of the guide hole 101 can be circular, elliptical, polygonal, arc-shaped, fan-shaped, fan-ring-shaped, heart-shaped, etc. By adopting different shapes, the final pattern display effect of the headlight can be obtained by adjusting it. The shape of the light guide 301 is adapted to the guide hole 101. Light enters from the circumferential sidewall of the light guide 301 and finally exits from the sidewall opposite to the drive unit 302. In this way, the light guide 301 can guide the light from the direction towards the lamp cover 4. The light guide 301 is made of optical-grade acrylic material that absorbs virtually no light, which can effectively reduce light loss and heat generation.

[0050] Reference Figures 3 to 6 Based on the mounting part 1 having multiple guide holes 101, in some exemplary embodiments, each guide hole 101 has a light inlet hole 102 on its wall. The light inlet hole 102 is located on the light transmission path from the light source 2 to the light guide part 301, and the light emitted by the light source 2 enters the corresponding guide hole 101 through each light inlet hole 102. Each light guide part 301 has a light shield 303 at one end. When each light guide part 301 moves within the guide hole 101, it can drive the light shield 303 to move between a first position exposing the light inlet hole 102 and a second position covering the light inlet hole 102.

[0051] With this configuration, the light inlet 102 in the wall of the guide hole 101 is located on the light transmission path from the light source 2 to the light guide 301. Light emitted from the light source 2 can only enter the guide hole 101 through the light inlet 102, which helps to reduce stray light. At the same time, the light-shielding part 303 at one end of the light guide 301 moves with the light guide 301. By blocking the light transmission path, the brightness switching of the pixel corresponding to a single light guide 301 can be more precise, and the contrast of the displayed pattern can be higher.

[0052] See Figure 5 and Figure 6 Based on the fact that the mounting part 1 has light inlet holes 102, in some exemplary embodiments, the light source 2 includes a light strip disposed on the mounting part 1, and the light guide module 3 also includes a light guide plate 304 coupled to the light strip. The light guide plate 304 is capable of guiding the light emitted by the light strip into each guide hole 101.

[0053] With this arrangement, the light strip used in the light source 2 can provide a longer light-emitting area compared to the traditional point light source 2. Combined with the light guide plate 304 coupled with the light strip, the light guide plate 304 can conduct and homogenize the light emitted by the light strip and then evenly guide it into each guide hole 101. The brightness of each light guide part 301 is uniform, and the displayed pattern is more uniform and beautiful, thus improving the visual quality of the vehicle light display.

[0054] Of course, the light source 2 can also be in the form of multiple LED beads. Specifically, multiple LED beads can be installed on the mounting part 1, with the light-emitting part of the LED bead inserted into the light hole 102, and each LED bead corresponding to a light guide part 301. However, when using multiple LED beads as point light sources 2, the LED beads do not work simultaneously. Some less frequently used LED beads have a very low utilization rate, resulting in excessive redundancy in the number of light sources 2 and increased energy consumption. Moreover, as the LED beads age over time, the degree of aging may vary, which may lead to different light intensities among the LED beads, resulting in unclear headlight display patterns.

[0055] At the same time, setting multiple LED beads or other similar point light sources 2 can also lead to more serious heat generation, especially when multiple pixels need to be densely displayed. The heat emitted by multiple light sources 2 inside the headlight dissipates slowly, which will lead to higher temperatures inside the headlight. This will not only accelerate the aging of the headlight, but may also cause damage to the point light sources 2.

[0056] Therefore, using a light strip as the light source 2, compared to setting a point light source 2 for each light guide 301, not only improves the display effect of the vehicle lights but also extends the service life of the vehicle lights module. The light strip and light guide plate 304 can also be modularly designed, making assembly more convenient and faster, and reducing maintenance difficulty.

[0057] Based on the light guide plate 304, and referring to Figures 3 to 6 In some exemplary embodiments, the light guide plate 304 has a plurality of insertion portions 3041, each of which corresponds to a light inlet hole 102, and each insertion portion 3041 is inserted into the corresponding light inlet hole 102.

[0058] As configured above, the insertion portion 3041 of the light guide plate 304 corresponds one-to-one with the light inlet hole 102 and is inserted into the light inlet hole 102. Light enters the guide hole 101 directly from the light guide plate 304 through the insertion portion 3041. This plug-in connection method shortens the light transmission distance between the light guide plate 304 and the guide hole 101, reduces the light consumption during transmission, and helps to enhance the light output intensity of the light guide portion 301.

[0059] Meanwhile, when assembling the light guide plate 304 and the mounting part 1, the insertion part 3041 of the light guide plate 304 is aligned and inserted into the corresponding light inlet hole 102, which completes the positioning and fixing of the light guide plate 304, reduces the number of assembly steps and parts, and reduces assembly costs and time.

[0060] Preferably, the opening of the light inlet 102 on the wall of the guide hole 101 can be set as a rectangle surrounding half of the guide hole 101, and the light emitting surface 3042 of the insertion part 3041 can be set as a curved surface flush with the wall of the guide hole 101. This arrangement not only ensures that the insertion part 3041 does not interfere with the movement of the light guide part 301, but also makes the light emitting surface 3042 of the insertion part 3041 larger, resulting in a better light emission effect.

[0061] The light guide plate 304 can be rectangular, with one sidewall abutting against the light strip and the opposite sidewall having the light-emitting surface 3042. The remaining sidewalls are reflective surfaces. Light guide dots are printed on the reflective surface of the light guide plate 304. When light entering the light guide plate 304 shines on the light guide dots, it will be diffusely reflected from the light-emitting surface 3042, achieving a point-to-point light emission effect.

[0062] Furthermore, in addition to the guide hole 101 provided in the mounting part 1, in some exemplary embodiments, a diffuse reflection layer is provided on the hole wall of each guide hole 101 to reflect the light irradiated onto the hole wall of the guide hole 101 into the light guide part 301.

[0063] In this way, the diffuse reflection layer provided on the wall of the guide hole 101 can reflect the light that shines on the wall of the hole into the light guide part 301. When light enters the guide hole 101, some light will inevitably shine on the wall of the hole. The diffuse reflection layer can reflect this part of the light that would have been absorbed by the wall of the hole back into the light guide part 301 and finally be guided out by the light guide part 301, reducing the loss of light in the guide hole 101.

[0064] Similarly, based on the provision of a light-shielding part 303 at one end of the light guide part 301, in some exemplary embodiments, each light-shielding part 303 is provided with a diffuse reflection layer on the sidewall facing the corresponding light guide part 301, so as to reflect the light irradiated on the sidewall of the light-shielding part 303 into the light guide part 301.

[0065] With this configuration, the diffuse reflection layer disposed on the side wall of the light guide 301 facing the light shield 303 will not absorb the light that shines on the side wall of the light shield 303 when the light guide 301 is in the first position. Instead, the light will be reflected into the light guide 301 by the diffuse reflection layer, which further increases the total amount of light that the light guide 301 can guide, thus improving the brightness of the headlight.

[0066] Preferably, a diffuse reflection layer can be provided on both the hole wall of each guide hole 101 and the side wall of the light guide 301 to produce a double diffuse reflection effect. This is beneficial to improving the utilization rate of light, making the light emitted by the light guide 301 brighter, improving the visual effect of the displayed pattern, and also having a certain energy-saving effect. The diffuse reflection layer enhances the uniformity of light, and the light guide 301 outputs light in a directional manner, which can significantly improve the contrast and clarity of the pattern displayed by the headlights.

[0067] Continue to refer to Figures 3 to 6 Based on the mounting part 1 having guide holes 101, in some exemplary embodiments, the mounting part 1 has an extension portion 103 extending in a preset direction, and the extension portion 103 fits against the inner wall of the lamp cover 4. Each guide hole 101 has an opening provided on the extension portion 103, and the lamp cover 4 covers the opening.

[0068] With this configuration, the extension portion 103 of the mounting portion 1 extends along a preset direction and fits against the inner wall of the headlight cover 4. This structure allows the light guided by the light guide portion 301 to directly illuminate the inside of the cover 4 through the opening, and then shine outward through the cover 4. This reduces the light leakage phenomenon caused by a large gap between the light guide portion 301 and the cover 4, which makes the displayed pattern on the cover 4 clearer and the edges more distinct, thus improving the visual effect.

[0069] Meanwhile, the extension portion 103 can be designed according to the shape and curvature of the headlight cover 4, so that it can fit tightly into the inner wall of the headlight cover 4 with different structures without modifying the headlight cover 4. The extension portion 103 can also support the headlight cover 4. When the headlight cover 4 is subjected to external force, the extension portion 103 can support the headlight cover 4, enhance the impact resistance of the headlight cover 4, and reduce the risk of damage or deformation of the headlight cover 4.

[0070] It should also be noted that the extension portion 103 can be set as one, with all the guide holes 101 set on the extension portion 103, resulting in better overall structural strength. Alternatively, there can be multiple extension portions 103, with at least one guide hole 101 set on each extension portion 103, which can reduce the volume and weight of the mounting part 1.

[0071] Reference Figure 4 Based on the fact that the mounting part 1 is provided with a guide hole 101, in some exemplary embodiments, each light guide part 301 is able to fit against the inner wall of the lamp cover 4 of the vehicle lamp when it is in the second position.

[0072] In this way, the light guide 301 is attached to the lamp cover 4 at the second position, and the lamp cover 4 can limit the movement of the light guide 301. When the light guide 301 abuts against the lamp cover 4, it reaches the second position. At the same time, when the light guide 301 is attached to the lamp cover 4 at the second position, the corresponding pixels are in an off state. From the outside, it is less likely to have uneven or shadowy visual effects, which helps to improve the display effect of the vehicle lights.

[0073] It should be noted that if the guide hole 101 is in the form of a circular hole, a guide structure needs to be provided between the light guide part 301 and the hole wall of the guide hole 101 to prevent the light guide part 301 from rotating in the guide hole 101. The guide structure can be, for example, a groove provided on the mounting part 1 and a slider provided on the light guide part 301. The slider is embedded in the groove, which can realize the function of guiding and preventing the rotation of the light guide part 301 along a preset direction.

[0074] Regarding the specific form of the driving unit 302, in some exemplary embodiments, each driving unit 302 includes an electromagnet 3021 provided on the mounting part 1 and a magnet 3022 provided on the corresponding light guide part 301. The electromagnet 3021 can drive the magnet 3022 to move the light guide part 301.

[0075] The drive unit 302 adopts a combination of electromagnet 3021 and magnet 3022. When the electromagnet 3021 is energized, it generates a magnetic field, which attracts or repels the magnet 3022 on the light guide unit 301, thereby driving the light guide unit 301 to move. It has a fast response speed and high working stability, which is beneficial to improving the service life of the vehicle lamp module.

[0076] In detail, the electromagnet 3021 is located at the end of the guide hole 101 away from the lamp cover 4, connected to the back plate housing 5, and its wiring can be set on the back plate housing 5. After the vehicle lamp module is assembled, it is connected to the vehicle system. The magnet 3022 can be set to the same shape as the cross-sectional shape of the light guide 301 and is bonded to the side of the light guide 301 facing away from the lamp cover 4.

[0077] Reference Figure 3 and Figure 4 In practical implementation, by changing the polarity direction of electromagnet 3021, the magnetic force between electromagnet 3021 and magnet 3022 can be changed. When the light guide 301 needs to be in the first position, electromagnet 3021 attracts magnet 3022, causing magnet 3022 to adhere to electromagnet 3021. At this time, the light guide 301 is in the first position, and light can enter the light guide 301 through light inlet hole 102. When the light guide 301 needs to be in the second position, electromagnet 3021 repels magnet 3022, causing magnet 3022 to adhere to lamp cover 4. At this time, the light guide 301 is in the second position, and magnet 3022 covers light inlet hole 102, acting as light shield 303. Using magnet 3022 as light shield 303 can reduce the number of parts in the vehicle lamp module and simplify the structure.

[0078] Of course, in addition to using an electromagnet 3021 and a magnet 3022, the drive unit 302 can also use mechanical devices such as an electric push rod or an airbag. For example, when the drive unit 302 uses an electric push rod, the light guide 301 is provided with a light-shielding part 303. The two ends of the electric push rod can be hinged to the mounting part 1 and the light-shielding part 303 respectively, and the movement of the light guide 301 can be achieved by extending and retracting the electric push rod. As another example, when the drive unit 302 uses an airbag, the airbag can be set to expand and contract in a preset direction. A diffuse reflection layer is arranged on the surface of the airbag, so that the airbag acts as the light-shielding part 303. When the airbag is inflated, it can push the light guide 301 to move to the second position and abut against the lampshade 4; when the airbag is deflated, it can pull the light guide 301 back, so that the light guide 301 is in the first position.

[0079] It is worth noting that, regarding the vehicle headlight module of this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 6 As shown, it may include, for example, a mounting part 1, a light strip, and a light guide module 3.

[0080] The mounting part 1 is provided with a guide hole 101, and a light inlet hole 102 is provided on the wall of the guide hole 101.

[0081] The light guide module 3 includes a light guide part 301 slidably disposed in the guide hole 101, an electromagnet 3021 fixed in the guide hole 101, a magnet 3022 bonded to the light guide part 301, and a light guide plate 304 inserted into the light inlet hole 102.

[0082] The light guide plate 304 is attached to the light strip and has a light-emitting surface 3042 that is flush with the wall of the guide hole 101.

[0083] The mounting part 1 is provided with an extension part 103, which abuts against the lamp cover 4 of the vehicle lamp, and the lamp cover 4 covers the position of the extension part 103 corresponding to the opening of the guide hole 101.

[0084] In the preferred embodiment of the above-mentioned vehicle lighting module, the specific settings and arrangements of the mounting part 1, the light strip and the light guide module 3, etc., can still be referred to the descriptions in the above-mentioned exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the mounting part 1, the light strip and the light guide module 3, etc., can also be referred to the descriptions in the above-mentioned exemplary embodiments.

[0085] The headlight module of this embodiment adopts the above design. By setting the driving unit 302 to drive the light guide 301 to move, the light guide 301 guides light at the first position and does not guide light at the second position. Each light guide 301 can be used as a pixel to create changes in brightness and darkness to display different patterns. Since each light guide 301 is a pixel, the headlight module can also be well adapted when used for non-developable curved surface headlights, which helps to improve the versatility of the headlight module.

[0086] Meanwhile, by using a light guide unit 301 to guide the light source 2, the luminous intensity is higher than that of OLED, which makes the pattern display clearer and improves the display effect.

[0087] An embodiment of the second aspect of this application provides a vehicle that includes the headlight module of the first aspect of this application.

[0088] In this embodiment, the vehicle, by setting the headlight module of the first aspect of this application, when the selected headlight is a non-developable curved lamp cover, can also achieve pattern pixelation display and dynamic change function by moving the light guide through multiple independent light guides 301, so that the headlight can display diverse patterns, symbols, or dynamic animations, realize richer vehicle interaction functions, make the vehicle more differentiated in appearance and function, and help improve the vehicle's quality of use and product competitiveness.

[0089] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
