Description

Technical Field

[0001] This application relates to the field of optical display, specifically to a vehicle lighting module, vehicle lighting, vehicle, projection method, and related devices. Background Technology

[0002] With the development of vehicle intelligence, consumers have developed more personalized demands for vehicle lights, such as welcome lights, projected patterns, and light carpets. Currently, pixel headlights used in vehicles have significant advantages in the diversity of welcome patterns and the projection range, showing potential to become the next generation of intelligent welcome projection lights. However, pixel headlights suffer from a relatively small field of view and a limited light projection range. Summary of the Invention

[0003] The embodiments of this application provide a vehicle headlight module, a vehicle headlight, a vehicle, a projection method, and related devices, which can flexibly adjust the illumination area of ​​the headlight module, expand the field of view of the headlight module, and achieve a wider range of illumination and projection.

[0004] In a first aspect, this application provides a vehicle lighting module for use in a vehicle. The vehicle includes a vehicle body, and the lighting module includes a light source, a first adjustment component, and a deflecting mirror. The light source is mounted on the vehicle body, and the light from the light source is emitted through its light-emitting surface. The first adjustment component is mounted on the vehicle body and connected to the deflecting mirror. The deflecting mirror includes an emission surface, and the first adjustment component can adjust the orientation of the emission surface of the deflecting mirror located in the light path of the light source, so as to deflect the propagation direction of the light passing through the deflecting mirror.

[0005] In this embodiment, the deflecting mirror can change its position in the light path of the lamp source, thereby changing the propagation direction of the light passing through the deflecting mirror. This can deflect the light closer to the vehicle body, allowing the light passing through the deflecting mirror to reach an area closer to the vehicle body, thus expanding the field of view of the headlights.

[0006] When the area around a vehicle can be illuminated, it can be used in vehicle welcome scenarios. As the driver approaches the vehicle, the vehicle can illuminate or project patterns into the path the driver is approaching, which not only helps the driver quickly find their vehicle in a dark environment, but also creates a warm atmosphere and optimizes the user experience.

[0007] When a vehicle is in motion, the light emitted from the headlights can create a light carpet effect after passing through a deflecting mirror. This turning light carpet can predict the vehicle's path in real time; as the vehicle is about to change lanes or turn, the light carpet bends accordingly, clearly indicating the vehicle's intention. This not only helps the driver better understand the vehicle's dynamics but also allows pedestrians and other vehicles to react in advance, preventing collisions.

[0008] In one possible implementation, the headlight module further includes a moving component connected between the first adjustment component and the vehicle body. The deflecting mirror has a non-operating state and a first operating state. When the deflecting mirror is in the non-operating state, it is located outside the optical path of the light source, and the light propagates along a first propagation direction. The moving component can move the first adjustment component and the deflecting mirror relative to the light source, so that the deflecting mirror is located in the optical path of the light source, with its incident surface facing the emitting surface of the light source, thus placing the deflecting mirror in the first operating state. In this state, light is emitted through the exiting surface of the deflecting mirror and propagates along a second propagation direction, which intersects the first propagation direction.

[0009] In this embodiment, when the deflecting mirror is in a non-operating state, the moving component can position the first adjusting component and the deflecting mirror outside the optical path of the lamp source, allowing the light from the lamp source to propagate along the first propagation direction. For example, when the deflecting mirror is in a non-operating state, the vehicle headlight can be in the low beam mode used during normal driving.

[0010] When the deflecting mirror is in its first working state, it illuminates the area in front of the vehicle. This allows it to greet the driver as they approach the vehicle from the front.

[0011] In scenarios where the illumination area of ​​the headlights needs to be shifted to the left or right of the vehicle, the active component, which can be adjusted by the first adjustment component, can drive the driven component to rotate, thereby causing the deflection mirror to rotate.

[0012] In one possible implementation, the first adjustment component includes a base, an active member, and a passive member. The base is connected to the moving component and has a mounting hole that penetrates the base. The outer periphery of the passive member is rotatably connected to the wall of the mounting hole. The passive member has a light-transmitting hole that penetrates the passive member along its axial direction. A deflecting mirror is connected to the wall of the light-transmitting hole. The active member is mounted on the base, and rotation of the active member can drive the passive member to rotate.

[0013] The deflecting mirror also includes a second working state, where the incident surface of the deflecting mirror faces the light-emitting surface of the lamp source. A driven wheel rotates the deflecting mirror, changing the orientation of its emitting surface to deflect the light passing through it. The driven wheel can rotate at any angle, allowing the deflecting mirror to rotate at any angle, thus enabling continuous changes in the direction of light deflection. This allows for fine-tuning of the deflection direction and more precise control over the angle of deflection. When vehicles are in motion, the road surface may be uneven; the dynamic control of the deflecting mirror by the driven wheel ensures stable light output. In static scenarios such as when vehicles are parked, the dynamic control of the deflecting mirror by the driven wheel can deflect the light, illuminating a larger projection area. The process of the driven wheel rotating the deflecting mirror is relatively simple, allowing for rapid adjustment of the mirror's state to adjust the direction of light deflection and quickly illuminate the desired area, providing a better user experience.

[0014] In this embodiment, when the deflecting mirror is in its second working state, it can illuminate areas such as the left front or right front of the vehicle. This allows for a side-facing welcome to the driver approaching the vehicle from the side.

[0015] In addition, when the light source forms a certain pattern, the headlights can also project onto the sides of the vehicle to create an ambient lighting effect, enhancing the user experience. Projecting onto the sides of the vehicle also helps illuminate the target lane area when changing lanes, improving driver safety and reducing blind spots.

[0016] When a vehicle is turning, the deflector can change the direction of light propagation, thereby illuminating the left or right turn lane with the headlights to achieve a turning illumination or side light carpet illumination effect, increasing the user's visibility area when turning in the dark and improving the user's turning safety.

[0017] The rotation angle of the deflecting mirror can also be greater than 90°. Specifically, the rotation is based on the thickness direction of the deflecting mirror and the position of the deflecting mirror in its first working state. For example, when the rotation angle of the deflecting mirror 13 is between 90° and 180° (inclusive of the 180° endpoint), the light path of the headlight is far from the bottom surface. This facilitates illumination of the slope during vehicle climbing, improving driver safety.

[0018] In one possible implementation, the first adjustment component further includes a transmission belt, which is sleeved around the outer periphery of the driving member and the driven member, and the driving member can drive the driven member to rotate via the transmission belt.

[0019] In this embodiment, the transmission belt can be a friction belt or a chain, etc. Friction belt drives typically have high transmission efficiency, effectively utilizing friction and exhibiting low energy loss during transmission. During torque transmission, the friction belt adheres tightly to both the driving and driven components, efficiently transferring power to the driven component through friction. In scenarios where the transmission component is a chain, the driving and driven components can be sprockets. The teeth on the sprockets mesh with the chain. When the driving component rotates, it drives the driven component to rotate via the chain.

[0020] In one possible implementation, the first adjustment component further includes a transmission wheel, which is rotatably connected to the base and meshes with the driving member and the driven member. The driving member can drive the driven member to rotate through the transmission wheel.

[0021] In this embodiment, the transmission wheels can adjust the transmission ratio between the driving member and the driven member. The transmission ratio is the ratio of the rotational speed of the driving member to the rotational speed of the driven member. By increasing or decreasing the number and size of the transmission wheels, the transmission ratio can be changed, thereby allowing the driven member to have a suitable rotational speed.

[0022] In one possible implementation, the first adjustment component further includes a rack slidably connected to the base, the rack meshing with the driving member and the driven member, and the driving member driving the driven member to rotate through the rack.

[0023] In this embodiment, the rack and pinion drive can maintain a constant transmission ratio, making power transmission stable and reliable, and providing precise control over output speed and torque.

[0024] In one possible implementation, the deflecting mirror is a Fresnel lens.

[0025] In this embodiment, the Fresnel lens achieves a lighter and thinner design by removing some material. This lightweight and thin design makes the Fresnel lens easier to install.

[0026] In one possible implementation, the headlight module further includes a second adjustment component connected between the light source and the vehicle body. The second adjustment component can adjust the orientation of the light-emitting surface of the light source, thereby changing the direction of light propagation.

[0027] In this embodiment, the refraction angle of the light from the deflecting mirror is limited. Therefore, by adjusting the direction of the light-emitting surface of the lamp source, the propagation direction of the light can be changed before refraction by the deflecting mirror. By superimposing the refraction effect of the deflecting mirror on the light, the degree of light deflection is greater, thereby achieving a wider range of illumination, expanding the field of view of the vehicle headlight, and thus making the vehicle headlight suitable for more usage scenarios.

[0028] In one possible implementation, when the deflecting mirror is in a non-working state, the area illuminated by the light source is a first preset area. When the deflecting mirror is in a first working state, the area illuminated by the light source is a second preset area. The distance from the edge of the first preset area away from the light source to the light source is greater than the distance from the edge of the second preset area away from the light source to the light source.

[0029] In one possible implementation, when the deflecting mirror is in the second working state, the area illuminated by the light through the deflecting mirror is a third preset area, and the distance from the edge of the first preset area away from the light source to the light source is greater than the distance from the edge of the third preset area away from the light source to the light source.

[0030] In one possible implementation, the third preset area is offset from the first preset area in the width direction of the vehicle body.

[0031] Secondly, this application provides a vehicle light, including a controller and a vehicle light module as described above, wherein the controller can control a first adjustment component to drive the deflection mirror body to move.

[0032] Thirdly, this application provides a vehicle, including a vehicle body, a controller, and a headlight module as described above. Both the controller and the headlight module are installed on the vehicle body. The controller can control the first adjustment component to drive the deflection mirror to move.

[0033] Fourthly, this application also provides a projection method applied to a vehicle, the vehicle including the headlight module as described above, the projection method including:

[0034] Based on the scene pattern of transportation vehicles, determine the first projection area;

[0035] Based on the first projection area, generate projection instructions;

[0036] Based on the projection command, the first adjustment component in the headlight module is controlled to move the deflection mirror in the headlight module so that the light from the headlight module passing through the deflection mirror is projected onto the first projection area.

[0037] In one possible implementation, after generating a projection command based on the first projection area and before controlling the first adjustment component in the headlight module to move the deflection mirror in the headlight module based on the projection command, the projection method further includes:

[0038] The projection command controls the moving components in the headlight module to move the deflecting mirror so that the deflecting mirror is positioned in the light path of the headlight module's light source.

[0039] In one possible implementation, before determining the first projection area in a vehicle-based scene mode, the projection method further includes:

[0040] The deflection mirror is positioned outside the light path of the lamp source so that the light emitted by the lamp source is projected onto a second projection area, which is different from the first projection area.

[0041] In one possible implementation, the first projection region includes a first sub-region and a second sub-region;

[0042] Based on projection commands, the first adjustment component in the headlight module is controlled to move the deflecting mirror in the headlight module, so that the light from the headlight module passing through the deflecting mirror is projected onto the first projection area, including:

[0043] Based on the projection command, the first adjustment component is controlled to move the deflection mirror body by a first angle so that the light from the headlight module passing through the deflection mirror body is projected onto the first sub-area;

[0044] Based on the projection command, the first adjustment component is controlled to move the deflection mirror body to a second angle so that the light from the headlight module passing through the deflection mirror body is projected onto the second sub-region; the first angle and the second angle are different, and the first sub-region and the second sub-region are different.

[0045] Fifthly, this application also provides a projection device, including a processor for performing the method described above.

[0046] Sixthly, this application also provides a chip including logic circuitry and an interface, wherein the logic circuitry and the interface are coupled.

[0047] The interface is used to input and / or output information, and the logic circuit is used to execute the methods described above.

[0048] In a seventh aspect, this application also provides a mobile terminal, including the projection device as described above, or the chip as described above.

[0049] Eighthly, this application also provides a computer-readable storage medium for storing a computer program, wherein when the computer program is executed, the method described above is performed.

Detailed Implementation

[0068] The specific embodiments of this application will now be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in other ways different from those described herein, and therefore, this application is not limited to these embodiments.

[0069] For ease of understanding, the terminology used in the embodiments of this application will be explained first.

[0070] Multiple: refers to two or more.

[0071] Connection: should be interpreted broadly. For example, the connection between A and B can be a direct connection between A and B, or an indirect connection between A and B through an intermediary.

[0072] The specific embodiments of this application will now be clearly described in conjunction with the accompanying drawings.

[0073] This application provides a vehicle that can flexibly adjust the illumination area of ​​the headlight module, expand the field of view of the headlight module, and achieve a wider range of illumination and projection.

[0074] Please see Figure 1 , Figure 1 This is a schematic diagram of a vehicle 1000 provided in an embodiment of this application in a working scenario. The vehicle 1000 in this embodiment can be a known vehicle such as a car, airplane, ship, or rocket, or it can be a newly emerging vehicle 1000 in the future. The car can be an electric vehicle, a gasoline-powered vehicle, or a hybrid vehicle, such as a pure electric vehicle, a range-extended electric vehicle, a hybrid electric vehicle, a fuel cell vehicle, or a new energy vehicle; this application does not specifically limit its type. The following description uses a vehicle 1000 as an example.

[0075] The vehicle 1000 includes a headlight 100 and a vehicle body 200. See also... Figure 2 , Figure 2 yes Figure 1 The diagram shows a partial structural representation of a vehicle headlight 100 mounted on a vehicle body 200. The headlight 100 includes a headlight module 10 and a controller 20. Both the headlight module 10 and the controller 20 are mounted on the vehicle body 200. The controller 20 is electrically connected to the headlight module 10. The controller 20 is capable of controlling the direction of light propagation from the headlight module 10.

[0076] The controller 20 can communicate with the computer system in the vehicle 1000 via the vehicle's bus to receive various information or control signals, and then send information to the headlight module to control the direction of light propagation of the headlight module, thereby achieving the desired lighting effect. It should be noted that, with technological advancements, the functionality of the controller 20 may be integrated into the vehicle's computer system, allowing the computer system to directly control the headlight module to change the direction of light propagation. For example, the controller 20 could be integrated into the cockpit domain controller. This application does not limit the specific operating method of the controller 20.

[0077] The vehicle light 100 can be an external or internal light fixture on a vehicle. For example, the vehicle light 100 can also integrate some sensing modules, such as integrating any of the sensing modules such as lidar, millimeter-wave radar or infrared detection devices into the vehicle light 100 to form a vehicle light 100 with integrated sensing and illumination.

[0078] In this embodiment, the lidar is combined with the intelligent driving system of the vehicle 1000. The lidar can monitor the surrounding environment in real time and provide the vehicle 1000 with timely obstacle avoidance and braking information, thereby improving driving safety.

[0079] Millimeter-wave radar measures the distance to a target by emitting electromagnetic waves and receiving the reflected echoes. Millimeter-wave radar can be used for blind spot monitoring, lane change assist at low speeds, emergency braking, adaptive cruise control, and other functions.

[0080] Infrared detection devices utilize electromagnetic radiation with longer wavelengths and lower frequencies for communication and detection. Infrared technology can be used to detect the airtightness of vehicle lights 100, ensuring the quality and performance of the lights by detecting gas leakage between the lamp cover and the bulb.

[0081] External lighting can include headlights or welcome lights. Headlights, also known as headlamps, are installed on both sides of the front of the vehicle for illuminating the road at night. Headlights include low beams and high beams. Low beams illuminate the road ahead without glare or causing discomfort to oncoming vehicles or other road users. High beams illuminate the road ahead further ahead. Welcome lights are mainly installed at the bottom of the doors or below the side mirrors. They automatically illuminate the area around the door when the door is opened or the driver approaches the vehicle, providing lighting for passengers getting in and out.

[0082] Interior lighting fixtures can include dome lights and ambient lights. Dome lights are used for illumination inside the vehicle at night or in dimly lit conditions. Ambient lights can be installed on the vehicle's interior and are non-illuminating lights used to create a specific ambiance. In some other applications, ambient lights can also be installed on the exterior of the vehicle.

[0083] The following description will use headlight 100 as an example. However, it should be noted that the headlight 100 in this application can be any type of headlight 100 used on the vehicle 1000, and is not limited to headlights.

[0084] In recent years, with the rapid development of electric vehicles, the importance and practical value of vehicle intelligence have gradually become prominent. At the same time, consumers have also developed more personalized demands for vehicle lights, such as welcome lights, "angel wings," and light carpets. However, traditional welcome lights are achieved through film printed with specific patterns, which has drawbacks such as limited pattern variety and a small projection area.

[0085] Pixelated headlights allow for individual control of the on / off state and brightness of each pixel area, providing a solid hardware foundation for intelligent vehicle lighting and generating significant buzz in the consumer market. Due to their distinct advantages in the diversity of welcome patterns and projection range, pixelated headlights have the potential to become the next generation of intelligent welcome projection lights.

[0086] However, existing pixelated headlights have a small field of view (less than 20 degrees horizontally and less than 10 degrees vertically), and the projection distance in front of the vehicle is usually greater than 8 meters, which greatly limits the welcoming range. In the light carpet scenario, it is also limited by the field of view and can generally only cover one lane in front, which can only be used for indicating width. Its lighting effect in more important scenarios such as lane changing and turning is very limited.

[0087] Based on this, this application provides a vehicle headlight module that can improve the field of view of the vehicle headlight 100 and meet the various large field of view lighting needs of the vehicle headlight 100. It can realize a variety of highly flexible new scenarios such as cornering lighting, turning light carpet, slope lighting, and large-scale welcoming.

[0088] Please continue reading. Figure 2 The headlight module 10 includes a light source 11, a first adjustment component 12, and a deflection mirror 13.

[0089] It should be noted that, Figure 2 The purpose of this illustration is solely to depict the connection relationship between the light source 11, the first adjustment component 12, the deflection mirror 13, the controller 20, and the vehicle body 200, and is not to specifically limit the connection positions, specific structures, or quantities of each device. Furthermore, the structure illustrated in this application's embodiments does not constitute a specific limitation on the vehicle lighting module 10. In other embodiments of this application, the vehicle lighting module 10 may include more or fewer components than illustrated, or combine certain components, or split certain components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of both.

[0090] The light source 11 is mounted on the vehicle body 200. The vehicle body 200 can be a basic structural component of a vehicle. The vehicle body 200 may include body panels, doors, windows, bumpers, headlight housings, taillight housings, front fenders, interior trim panels, and other body accessories. The light source 11 provided in this embodiment can be mounted on any part of the vehicle body 200.

[0091] Light from lamp source 11 is emitted through its light-emitting surface. A first adjustment component 12 is installed on the vehicle body 200 and is connected to a deflecting mirror 13. The first adjustment component 12 can adjust the deflecting mirror 13 located in the light path of lamp source 11 to change the orientation of the emitting surface of the deflecting mirror 13, thereby deflecting the light passing through the deflecting mirror 13. The principle of light deflection can be based on reflection, refraction, or diffraction, etc. The following explanation uses the refraction of light by the deflecting mirror 13 as an example.

[0092] In this embodiment, the deflecting mirror 13 can change its position in the optical path of the lamp source 11, thereby changing the propagation direction of the light passing through the deflecting mirror 13. It can deflect the light closer to the vehicle body, so that the light passing through the deflecting mirror 13 can reach the area closer to the vehicle body, thereby expanding the field of view of the headlight 100.

[0093] When the area around vehicle 1000 can be illuminated, it can be used in vehicle welcome scenarios. When the driver approaches the vehicle, the vehicle can illuminate or project a pattern into the path the driver is approaching, which not only helps the driver quickly find their vehicle in a dark environment, but also creates a warm atmosphere and optimizes the user experience.

[0094] When the vehicle 1000 is in motion, the light emitted by the light source 11, after passing through the deflecting mirror 13, can form a light carpet effect. This turning light carpet can predict the vehicle's path in real time. When the vehicle is about to change lanes or turn, the light carpet bends accordingly, clearly indicating the vehicle's driving intention. This not only helps the driver better understand the vehicle's dynamics but also allows surrounding pedestrians and vehicles to react in advance, avoiding collisions.

[0095] The light source 11 can be a pixel-type headlight, which is based on micromirror matrix technology or LED matrix technology and is composed of a large number of tiny light-emitting units (pixels). These pixels can be independently controlled in terms of switching and brightness, thereby achieving precise control over the light distribution and illumination range. The light source 11 can also project more complex graphics such as text or traffic signs, as well as videos, and can be used in driver assistance and entertainment scenarios.

[0096] Specifically, the light source 11 can be a digital light processing projector (DLP), a liquid crystal on silicon (LCoS), a thin film transistor liquid crystal display (TFT-LCD), a micro light emitting diode (Micro-LED), a silicon-based OLED (Micro-OLED), etc.

[0097] The deflecting mirror 13 can be a mirror that can change the direction of light propagation. The deflecting mirror 13 can be a single-lens refractor or a compound-lens refractor. A single-lens refractor can be a single mirror body. Single-lens refractors have a simple structure and low cost. Compound-lens refractors are typically composed of multiple convex and concave lenses of different forms and functions. Compound-lens refractors can correct various aberrations, thereby providing clearer and higher-quality images.

[0098] Please refer to the following: Figure 3 and Figure 4 , Figure 3 yes Figure 2 A schematic diagram of one structure of the deflecting mirror 13 is shown. Figure 4 yes Figure 3 The diagram shows a cross-sectional view of the deflecting mirror 13. This application uses a Fresnel lens as an example for illustration. Exemplarily, the Fresnel lens provided in this embodiment can be made of polyolefin materials, glass, plastics, composite materials, etc.

[0099] A complete Fresnel lens, viewed in cross-section, has a surface composed of a series of serrated grooves, with an elliptical arc at its center. Each groove can be considered an independent microlens, which adjusts light rays into parallel or focused light. When light enters from one side of the lens, it is refracted and diffracted by these grooves, focusing into a point on the other side of the lens or exiting as parallel light. The Fresnel lens in the embodiments of this application can be part of a complete Fresnel lens.

[0100] In this embodiment, the Fresnel lens achieves a lighter and thinner design by removing some material. This lightweight and thin design makes the Fresnel lens easier to install.

[0101] In one possible implementation, please refer to [further details]. Figure 3 and Figure 4 The deflecting mirror 13 includes a first Fresnel lens 131 and a second Fresnel lens 132. The first Fresnel lens 131 and the second Fresnel lens 132 are stacked together.

[0102] The first Fresnel lens 131 includes a first incident surface 1311 and a first exit surface 1312. The first incident surface 1311 can be a plane, a sphere, or a freeform surface. The first incident surface 1311 is the incident surface of the light rays of the first Fresnel lens 131. The first exit surface 1312 is a first sawtooth surface. The first sawtooth surface includes multiple strip-shaped optical surfaces 1313 (or partially annular or linear) and connecting surfaces 1314. The optical surfaces 1313 and the connecting surfaces 1314 are bent and connected to form sawtooth. The connecting surfaces 1314 can be perpendicular to the first incident surface 1311. The strip-shaped optical surfaces 1313 can be spherical surfaces with a certain curvature. The strip-shaped optical surfaces 1313 are also the Fresnel surfaces of the Fresnel lens. The strip-shaped optical surfaces 1313 are the exit surfaces of the light rays.

[0103] The second Fresnel lens 132 includes a second incident surface 1321 and a second exiting surface 1322. The second incident surface 1321 is adapted to the first exiting surface 1312. The second incident surface 1321 is attached to the first exiting surface 1312. The second exiting surface 1322 includes a plurality of strip-shaped optical surfaces 1323 (or partially annular or linear) and a connecting surface 1324. The optical surfaces 1323 and the connecting surface 1324 are bent and connected to form a sawtooth pattern. The strip-shaped optical surfaces 1323 can be spherical surfaces with a certain curvature. The curvature of the strip-shaped optical surfaces 1323 of the second exiting surface 1322 is different from the curvature of the optical surfaces 1313 of the first exiting surface 1312. For example, the curvature of the optical surfaces 1323 of the second exiting surface 1322 can be smaller than the curvature of the first exiting surface 1312.

[0104] For example, the incident surface (first incident surface 1311) and the exit surface (second exit surface 1322) of the deflecting mirror 13 can also be interchanged. That is, the deflecting mirror 13 can be flipped so that the sawtooth exit surface (second exit surface 1322) of the Fresnel lens faces the light source 11. This application does not limit the way the deflecting mirror 13 is used.

[0105] In this embodiment, two Fresnel lenses are stacked. Increasing the number of material layers of the Fresnel lens can increase the number of reflections and refractions of light inside the lens, thereby enhancing the refraction effect.

[0106] For another possible implementation, please refer to Figure 5 , Figure 5 yes Figure 2 The diagram shows another structural schematic of the deflecting mirror 13. The deflecting mirror 13 can be a Fresnel lens. The deflecting mirror 13 can also be an arc-shaped Fresnel lens. The deflecting mirror 13 includes an incident light surface 1301 and an exit light surface 1302. The incident light surface 1301 and the exit light surface 1302 are arranged opposite to each other in the thickness direction of the deflecting mirror 13. The incident light surface can be an arc-shaped concave surface, and the exit light surface can be a sawtooth surface.

[0107] In this embodiment, the curved Fresnel lens can alter the distribution pattern of light. Compared to a planar lens, a curved lens may distribute light more evenly over a wider area or produce stronger light intensity in certain specific directions. Furthermore, the curved Fresnel lens can guide light from the lamp source 11 onto the projection area while maintaining image sharpness and brightness.

[0108] The first adjustment component 12 is connected between the vehicle body 200 and the deflecting mirror body 13. The first adjustment component 12 can adjust the orientation of the light-emitting surface of the deflecting mirror body 13 to adjust the propagation direction of light passing through the deflecting mirror body 13.

[0109] When the deflecting mirror 13 is the Fresnel lens described above, the first adjustment component 12 can rotate the Fresnel lens, and the central axis of its rotation can be the physical center point of the Fresnel lens. It should be noted that the center point of the Fresnel lens is offset from the center of the annular optical surface 1313 (or part of the annular optical surface 1313) of the Fresnel plane.

[0110] When the deflecting mirror 13 is a conventional refraction mirror such as a convex lens or a concave lens as described above, the first adjustment component 12 can also adjust the relative position of the convex lens or concave lens and the light source so that the convex lens or concave lens is tilted or translated, thereby changing the propagation direction of the light passing through the deflecting mirror 13.

[0111] The following description uses the first adjustment component 12 adapted to a Fresnel lens as an example. However, it should be understood that the first adjustment component 12 is not limited to this.

[0112] In the first possible implementation, please refer to [the relevant documentation]. Figure 6 and Figure 7 , Figure 6 yes Figure 2 The diagram shows a structural schematic of the first adjustment component 12 and the deflection mirror body 13 assembled at an angle. Figure 7 yes Figure 6 The diagram shows the structure of the first adjustment assembly 12 assembled with the deflecting mirror body 13 at another angle. The first adjustment assembly 12 includes a base 121, an active member 122, and a driven member 123.

[0113] The base 121 is connected to the vehicle body 200. The base 121 is provided with a mounting hole 1211, which extends through the base 121 along its thickness direction. The wall of the mounting hole 1211 may be provided with a low-friction structure 124. The low-friction structure 124 may be a bearing, a copper ring, or other self-lubricating structure.

[0114] For example, a bearing may include an inner ring, an outer ring, and rolling elements. The inner ring is located inside the outer ring. The rolling elements are located between the inner and outer rings to reduce friction between them and to transmit loads.

[0115] The outer ring of the bearing can be fixedly connected to the wall of the mounting hole 1211. Alternatively, the outer ring of the bearing can be integrally formed with the base 121. The inner ring of the bearing can be fixedly connected to the driven member 123. Alternatively, the inner ring of the bearing can be integrally formed with the driven member 123.

[0116] The follower 123 is rotatably connected to the wall of the mounting hole 1211 via a low-friction structure 124. The follower 123 can be an annular structure. The follower 123 is provided with a light-transmitting hole 1231, which extends through the follower 123 along its axial direction. The wall of the light-transmitting hole 1231 is connected to the deflecting mirror body 13.

[0117] The driving element 122 is mounted on the base 121. The rotation of the driving element 122 can drive the driven element 123 to rotate.

[0118] For example, the first adjustment component 12 may further include a motor 128. The motor 128 may be connected to the side of the base 121 opposite to the driving member 122. The motor 128 includes a body 1281 and an electric shaft 1282. The body 1281 is connected to one end of the electric shaft 1282. The body 1281 may be connected to the base 121. The end of the electric shaft 1282 opposite to the body 1281 may pass through the base 121 and connect to the driving member 122. The driving member 122 may be a gear, and the driven member 123 may be a gear. The diameter of the driven member 123 may be larger than the diameter of the driving member 122. The driving member 122 may directly mesh with the driven member 123. When the driving member 122 rotates under the drive of the motor 128, the driving member 122 can drive the electric shaft 1282 to rotate, and the rotation of the electric shaft 1282 drives the driven member 123 to rotate, thereby driving the deflecting mirror body 13 to rotate. The motor 128 can also be other mechanisms that can provide power to the drive element 122.

[0119] In this embodiment, the first adjustment component 12 can drive the deflection mirror 13 to rotate, changing the orientation of the light-emitting surface of the deflection mirror 13, thereby changing the propagation direction of the light passing through the deflection mirror 13. While keeping the position of the light source 11 stationary, the propagation direction of the vehicle headlight 100 can be changed so that the illuminated area can be closer to the light source 11 (i.e., closer to the vehicle body 200), achieving a wider range of illumination and projection, thus achieving effects such as ultra-near-field welcome lights or turning light carpets.

[0120] In the second possible implementation, unlike the first possible implementation, the first adjusting component 12 further includes a transmission component. This transmission component can be a drive wheel, friction belt, chain, or rack, etc.

[0121] Please see Figure 8 , Figure 8 yes Figure 2The diagram shows the structure of the first adjustment component 12, including the transmission wheel 125. In applications where the transmission component is the transmission wheel 125, the transmission wheel 125 can be located between the driving component 122 and the driven component 123. The transmission wheel 125 can mesh with both the driving component 122 and the driven component 123. When the driving component 122 rotates under the drive of a power structure such as a motor 128, the driving component 122 can drive the driven component 123 to rotate via the transmission wheel 125, thereby causing the deflection mirror body 13 to rotate.

[0122] The transmission wheel 125 can adjust the transmission ratio between the driving member 122 and the driven member 123. The transmission ratio is the ratio of the rotational speed of the driving member 122 to the rotational speed of the driven member 123. By increasing or decreasing the number and size of the transmission wheels 125, the transmission ratio can be changed, thereby allowing the driven member 123 to have a suitable rotational speed.

[0123] Please see Figure 9 , Figure 9 yes Figure 2 The diagram shows a first adjustment assembly 12 including a friction belt 126. In applications where the transmission component is the friction belt 126, the friction belt 126 can be fitted around the outer periphery of the driving member 122 and the driven member 123. When the driving member 122 rotates under the drive of a power structure such as a motor 128, the driving member 122 can drive the friction belt 126, thereby driving the driven member 123 to rotate, so that the deflecting mirror body 13 can rotate.

[0124] Friction belt 126 transmission typically has high transmission efficiency, effectively utilizing friction and exhibiting low energy loss during transmission. During torque transmission, the friction belt 126 closely adheres to the driving member 122 and the driven member 123, efficiently transmitting power to the driven member 123 through friction.

[0125] When the transmission component is a chain, the driving component 122 and the driven component 123 can be sprockets. The teeth on the sprockets mesh with the chain. When the driving component 122 rotates, it drives the driven component 123 to rotate via the chain.

[0126] Chain drives are generally highly reliable, do not slip, and can operate stably at low speeds. This characteristic allows chain drives to maintain high transmission efficiency and reliability.

[0127] Please see Figure 10 , Figure 10 yes Figure 2 The diagram shows the structure of the first adjustment component 12, which includes a rack 127. In applications where the rack 127 is the transmission component, the driving component 122 and the driven component 123 can mesh with the rack 127. When the driving component 122 rotates under the drive of a power structure such as a motor 128, the driving component 122 can drive the rack 127 to move, thereby driving the driven component 123 to rotate.

[0128] The rack and pinion 127 transmission can maintain a constant transmission ratio, making power transmission stable and reliable, and providing precise control over output speed and torque.

[0129] In other possible implementations, the first adjustment component 12 can also be implemented by designing other specific transmission mechanisms, including but not limited to worm gears, connecting rod devices, rocker arms, crankshafts, cams, pneumatic mechanisms, etc.

[0130] For some possible implementation methods, please refer to the following: Figure 2 and Figure 11 , Figure 11 yes Figure 1 The diagram shows the structure of the vehicle headlight 100 installed on the vehicle body 200 in different states. Figure 11 The diagram in section a is a structural schematic of the headlight 100 when the deflection mirror of the headlight 100 is in a non-working state. Figure 11 The middle b-section diagram is a structural schematic diagram of the headlight 100 when the deflection mirror of the headlight 100 is in the first working state. Figure 11 The diagram in section C is a structural schematic of the headlight 100 when the deflecting mirror of the headlight 100 is in the second working state. Figure 11 The middle d-section diagram is another structural schematic diagram of the headlight 100 when the deflecting mirror of the headlight 100 is in the second working state. Figure 11 The diagram in the middle is another structural schematic diagram of the headlight 100 when the deflection mirror of the headlight 100 is in the second working state.

[0131] The headlight module 10 also includes a moving component 14. The moving component 14 is connected between the base 121 of the first adjustment component 12 and the vehicle body 200. Exemplarily, the moving component 14 can be a telescopic rod (not shown) and a motor (not shown). The motor can be connected to one end of the telescopic rod. The motor is mounted on the vehicle body 200. The other end of the telescopic rod is fixedly connected to the base 121 of the first adjustment component 12.

[0132] The deflecting mirror 13 includes a non-working state, a first working state, and a second working state.

[0133] During the use of the vehicle headlight 100, the controller 20 can determine the working status of the vehicle headlight 100, or the controller 20 can receive signals or instructions from the cockpit or other control domains, and based on the instructions of the working status, control the drive device to drive the moving component 14 and the first adjustment component 12 to move, so that the deflecting mirror body 13 is in different working states.

[0134] Specifically, please refer to the following: Figure 11 and Figure 12 , Figure 12yes Figure 1 The diagram shows the structure of the illuminated area of ​​the vehicle 1000 under different usage scenarios. When the controller 20 determines that the vehicle 1000 needs to illuminate the first preset area 1110, it can control the moving component 14 to position the deflecting mirror 13 outside the light path of the light source 11, thus putting the deflecting mirror 13 into a non-operating state. Figure 11 As shown in Figure a, when the deflecting mirror is in a non-working state, the telescopic rod can retract, so that the first adjusting component 12 and the deflecting mirror 13 are outside the light path of the lamp source 11, and the light from the lamp source 11 propagates along the first propagation direction. At this time, the area illuminated by the light from the lamp source 11 is the first preset area 1110. For example, when the deflecting mirror 13 is in a non-working state, the vehicle headlights can be in the low beam state during normal driving. The first preset area 1110 can be the area illuminated by the vehicle's low beam headlights.

[0135] like Figure 11 As shown in Figure b, when the controller 20 determines that the vehicle 1000 needs to illuminate an area other than the first preset area 1110, the controller 20 can control the motor 128 to extend the telescopic rod so that the deflecting mirror 13 is located in the optical path of the light source 11. The incident surface of the deflecting mirror 13 faces the emitting surface of the light source 11, and the serrations of the serrated surface of the deflecting mirror 13 face downwards (towards the bottom surface), thereby putting the deflecting mirror 13 into a first working state. The first working state can be understood as the state in which the deflecting mirror 13 is located in the optical path of the light source 11, and the driven member 123 of the first adjustment component 12 does not rotate.

[0136] The deflecting mirror 13 allows some or all of the light to pass through. The light is emitted from the exit surface of the deflecting mirror 13 and propagates along a second propagation direction, which intersects with the first propagation direction. That is, the second propagation direction and the first propagation direction are different directions. When the deflecting mirror 13 is in the first working state, the area illuminated by the light passing through the deflecting mirror 13 is the second preset area 1120. The distance D2 from the edge of the second preset area 1120 away from the light source 11 to the light source 11 is less than the distance D1 from the edge of the first preset area 1110 away from the light source 11 to the light source 11.

[0137] In this embodiment, when the deflecting mirror 13 is in the first working state, the deflecting mirror 13 can illuminate the area in front of the vehicle. Thus, when the driver approaches the vehicle 1000 from the front, it can greet the driver.

[0138] When the deflecting mirror 13 is in the first working state, and the controller 20 determines that the illumination area of ​​the vehicle headlight 100 needs to be shifted to the left or right of the vehicle 1000, the controller 20 can drive the active member 122 of the first adjustment component 12 to rotate via the motor 128, so that the active member 122 drives the driven member 123 to rotate, thereby causing the deflecting mirror 13 to rotate, so that the deflecting mirror 13 is in the second working state. The second working state of the deflecting mirror 13 can be understood as the state in which the deflecting mirror 13 is located in the optical path of the lamp source 11, and the direction of the serrated surface of the deflecting mirror 13 changes relative to when the deflecting mirror 13 is in the first working state.

[0139] Please refer to the following: Figure 11 When the deflecting mirror 13 rotates clockwise by α1, where α1 can range from 0 to 90° (including the endpoint 90°), the serrated edge of the deflecting mirror 13 faces the right side of the vehicle 1000. Clockwise rotation of the deflecting mirror 13 means that it rotates about the X-direction as its axis, with its position in the first working state as a reference position, and the direction of rotation is clockwise when viewed from the exit surface of the deflecting mirror 13. The illumination area of ​​the headlight 100 is at its right extreme position.

[0140] When the deflecting mirror 13 rotates counterclockwise by α2, where α2 ranges from 0 to 90° (inclusive of the endpoint 90°), the serrated edge of the deflecting mirror 13 faces the left side of the vehicle 1000. The illumination area of ​​the headlight 100 is at its left extreme position. Specifically, the counterclockwise rotation of the deflecting mirror 13 means that the deflecting mirror 13 rotates about the X-direction as its axis, with its position in the first working state as its reference position, and the direction of rotation of the deflecting mirror 13 is counterclockwise when viewed from its exit surface.

[0141] When the deflecting mirror 13 is in the second working state, the area illuminated by the light through the deflecting mirror 13 is the third preset area 1130, and the distance D3 from the edge of the third preset area 1130 away from the light source 11 to the light source 11 is the same as that from the light source 11. The third preset area 1130 and the first preset area 1110 are offset in the width direction (X direction) of the vehicle body 200.

[0142] In this embodiment, when the deflecting mirror 13 is in its second working state, it can illuminate areas such as the left front or right front of the vehicle. This allows for a side-facing welcome to the driver approaching the vehicle 1000 from the side of the vehicle.

[0143] In addition, when the light source 11 forms a certain pattern, the headlight 100 can also project onto the side of the vehicle to create an ambient lighting effect, enhancing the user experience. Projecting onto the side of the vehicle also helps illuminate the target lane area when changing lanes, improving driver safety and reducing blind spots.

[0144] When the vehicle 1000 is turning, the deflector 13 can change the direction of light propagation, thereby illuminating the left or right turn lane with the headlights 100 to achieve a turning or side light carpet illumination effect, improve the user's visibility area when turning in the dark, and enhance the user's turning safety.

[0145] Please refer to the following: Figure 11 The middle e-part graph and Figure 12 The deflecting mirror 13 can also rotate clockwise or counterclockwise by α3, where α3 is greater than 90°. For example, α3 ranges from 90° to 180° (inclusive). When the deflecting mirror 13 rotates by α3, the light path of the headlight 100 is deflected away from the ground, and the area illuminated by the headlight 100 can be the fourth preset area 1140. The distance D4 from the edge of the fourth preset area 1140 away from the light source 11 to the light source 11 is greater than the distance D1 from the edge of the first preset area 1110 away from the light source 11 to the light source 11. This facilitates the vehicle 1000 illuminating the slope during uphill driving, or illuminating a distant position in front of the vehicle when the user needs high beam illumination, thus improving driver safety.

[0146] In some other embodiments, the moving component 14 can also be a swinging structure. When the deflecting mirror 13 changes from a non-operating state to a first operating state, the moving component 14 can swing, causing the first adjusting component 12 to swing, thereby swinging the deflecting mirror 13 from outside the optical path of the lamp source 11 to within the optical path of the lamp source 11. The moving component 14 provided in this application embodiment can be any common transmission structure for moving the deflecting mirror 13 from outside the optical path of the lamp source 11 to within the optical path of the lamp source 11. This application does not limit the specific structure of the moving component 14.

[0147] In some other possible embodiments, please refer to [reference needed]. Figure 2 The headlight module 10 also includes a second adjustment component 16, which is connected between the light source 11 and the vehicle body 200. The second adjustment component 16 can adjust the orientation of the light-emitting surface of the light source 11, thereby changing the direction of light propagation. When the second adjustment component 16 adjusts the light propagation of the light source, the deflecting mirror 13 can cover all the light, preventing light from leaking out of the deflecting mirror 13 and causing an unclear lighting area.

[0148] In this embodiment, the deflection mirror 13 has a limited refraction angle for the light from the light source. Therefore, by adjusting the direction of the light-emitting surface of the lamp source 11, the propagation direction of the light can be changed before refraction by the deflection mirror 13. By superimposing the refraction effect of the deflection mirror 13 on the light, the degree of light deflection is greater, thereby achieving a wider range of illumination, expanding the field of view of the vehicle lamp 100, and thus enabling the vehicle lamp 100 to be applicable to more usage scenarios.

[0149] This application also provides a projection method for a vehicle headlight 100. Please refer to [link / reference]. Figure 13 , Figure 13 yes Figure 1 A flowchart illustrating the projection method of the vehicle headlight 100 is shown. This projection method is applied to the vehicle headlight module 10 described in the above embodiments. The projection method includes:

[0150] S100: Determine the first projection area based on the scene mode of vehicle 1000;

[0151] Specifically, controller 20 can be used to execute step S100. Controller 20 can be the controller of the vehicle lighting module 10 or a controller of other domains. Controllers of other domains include terminal wireless control, remote key, vehicle cockpit domain controller, vehicle sensors, etc. The vehicle lighting module 10 can also acquire information from such controller 20 to determine the scene mode of the vehicle 1000. Based on the scene mode of the vehicle 1000, the controller 20 of the vehicle lighting module 10 or other domain controller determines the first projection area.

[0152] For example, the controller 20 determines, based on information from the cockpit domain controller, that the scene mode of the vehicle 1000 is in light carpet illumination mode, and determines the first projection area as... Figure 12 The second preset area 1120 or the third preset area 1130 shown are indicated. Please refer to the references. Figure 11 and Figure 12 For example, the first projection area is determined to be the second preset area 1120, the distance D2 from the edge of the second preset area 1120 away from the light source 11 to the light source 11 is determined, and the field of view angle range parameters are determined.

[0153] Alternatively, the aforementioned controller 20 determines that the vehicle 1000 is in near-field welcoming mode based on the sensors of the vehicle 1000, and determines the first projection area as... Figure 12 One of the second preset region 1120 or the third preset region 1130 shown. If it is the third preset region 1130, the distance D3 from the edge of the region of the third preset region 1130 away from the light source 11 to the light source 11 is determined, and the field of view angle range parameter is determined.

[0154] S200: Generate a projection command based on the first projection area. This projection command can be directly acquired by the controller 20 of the headlight module 10, or it can be a command received by the headlight module 10 from another domain controller. The projection command instructs the headlight module 10 to project a corresponding image into the first projection area.

[0155] In some possible embodiments, the projection command includes projection area information, and the controller 20 of the headlight module 10 generates specific parameters for controlling the first adjustment component 12 based on the projection area information. The specific parameters for controlling the first adjustment component 12 include the rotation angle of the active member 122, the rotation speed of the active member 122, etc. For example, if it is necessary to deflect the mirror body 13 by 90 degrees, the controller 20 of the headlight module 10 will control the active member 122 of the first adjustment component 12 to drive the driven member 123 to rotate by 90 degrees.

[0156] In some possible embodiments, the projection command includes specific parameters for controlling the first adjustment component 12. These parameters include the rotation angle of the active member 122 and its rotation speed. For example, if the mirror body 13 needs to be rotated 90 degrees, the controller 20 of the headlight module 10 will control the active member 122 of the first adjustment component 12 to rotate the driven member 123, causing the driven member 123 to rotate 90 degrees, thereby rotating the mirror body 13 by 90 degrees.

[0157] S300: Based on the projection command, control the first adjustment component 12 in the headlight module 10 to drive the deflection mirror 13 in the headlight module 10 to move, so that the light from the headlight module 10 passing through the deflection mirror 13 is projected onto the first projection area.

[0158] The adjustment parameters include the rotation angle, rotation direction, and / or rotation speed of the deflecting mirror 13. For example, the controller 20 controls the first adjustment component 12 to rotate the deflecting mirror 13 clockwise by α1, and the first projection area can be the third preset area 1130 mentioned above. It should be noted that the first projection area can be any projection area of ​​the light source 11 after being deflected by the deflecting mirror 13. The propagation direction of the deflected light is different from the propagation direction of the light that has not passed through the deflecting mirror 13. The deflecting mirror 13 can bring the projection position of the light source 11 closer, and can also flexibly adjust the projection position according to actual needs, thereby meeting the needs of different welcoming scenarios.

[0159] In another possible implementation, after the controller of the headlight module generates a corresponding projection command based on the first projection area, and before the controller of the headlight module controls the first adjustment component to drive the deflection mirror body to move according to the specific parameters of the projection command, the projection method further includes:

[0160] S400: Controls the moving components in the headlight module according to the projection command to drive the deflection mirror to move, so that the deflection mirror is located in the light path of the lamp source in the headlight module.

[0161] For example, the controller 20 can control the moving component 14 via the motor 128 to move the deflecting mirror 13 a preset distance so that the light emitted by the light source 11 passes through the deflecting mirror 13 or does not pass through the deflecting mirror 13, thereby switching between the normal lighting mode and the near-field projection mode of the vehicle headlight 100.

[0162] In another possible implementation, before the controller determines the first projection area based on the scene pattern of the vehicle, the projection method further includes:

[0163] The deflection mirror is positioned outside the light path of the lamp source so that the light emitted by the lamp source is projected onto a second projection area, which is different from the first projection area.

[0164] The controller 20 of the headlight module 10 illuminates a second projection area according to a projection command. The second projection area is the first preset area 1110 mentioned above. The second projection area can be the projection area where the light from the lamp source 11 has not passed through the deflecting mirror 13.

[0165] It should be noted that this application does not limit the image information carried by the light. For example, in normal projection mode, the projection of the light from light source 11 is used for road lighting. As another example, in near-field projection mode, the projection of the light from light source 11 can achieve a welcoming effect similar to ambient lighting.

[0166] In one possible use case, the first projection area includes a first sub-region and a second sub-region;

[0167] Based on the projection command, the first adjustment component 12 in the headlight module 10 is controlled to move the deflecting mirror 13 in the headlight module 10, so that the light from the headlight module 10 passing through the deflecting mirror 13 is projected onto the first projection area, including:

[0168] Based on the projection command, the first adjustment component 12 is controlled to drive the deflection mirror 13 to move by a first angle so that the light from the headlight module 10 passing through the deflection mirror 13 is projected onto the first sub-region.

[0169] Based on the projection command, the first adjustment component 12 is controlled to move the deflection mirror 13 to a second angle so that the light from the headlight module 10 passing through the deflection mirror 13 is projected onto the second sub-region; the first angle and the second angle are different, and the first sub-region and the second sub-region are different.

[0170] In this usage scenario, a corresponding projection pattern is formed according to the dynamic scene in the scene mode of the same vehicle 1000. The dynamic scene refers to the switching between different sub-projection areas within the first projection area.

[0171] This can be understood as a projection transformation from one dynamic scene to another. A dynamic scene refers to a change in usage state, such as a user moving their activity point within a scene mode area.

[0172] For example, the scene mode is a near-field welcome scene, which dynamically projects based on changes in the user's position.

[0173] For details, please refer to Figure 14 , Figure 14 This is a schematic diagram showing the distribution of multiple sub-regions within the first projection area A. In the near-field welcome scene mode, the first projection area A is divided into multiple sub-projection areas based on the user's position, such as the first sub-region A1 and the second sub-region A2. The user is initially located in the first sub-region A1. The user moves within the first projection area A corresponding to the near-field welcome, moving from the first sub-region A1 to the second sub-region A2, and is located in the second sub-region A2 at the second time. For example, the user is located in the first sub-region A1 at time t1 and in the second sub-region A2 at time t2.
