Description

Technical Field

[0001] This application relates to the field of vehicle lighting technology, and more particularly to a vehicle headlight projection system and a vehicle. Background Technology

[0002] With the maturity and development of vehicle technology, the functions of vehicle lights are becoming increasingly powerful. Automotive lighting is evolving from traditional floodlighting to a direction that simultaneously incorporates ADB (Adaptive Driving Beam) and ground projection, resulting in a diversification of vehicle headlight projection technology. Due to the advantages of DMD (Digital Micromirror Device) structures, such as high brightness and low system complexity, the application of DMDs in vehicle headlight projection systems is becoming increasingly widespread. However, in vehicle headlight projection systems that combine a lighting system, a DMD, and a projection lens for illumination, the brightness is insufficient when the illumination range is large, and conversely, the illumination range is small when the brightness is high; a large illumination range and high brightness are incompatible. Summary of the Invention

[0003] This application provides a vehicle headlight projection system and a vehicle, which solves the technical problem that the illumination brightness of a vehicle headlight projection system is insufficient when the illumination range is large, and the illumination range is small when the illumination brightness is high, and that a large illumination range and high brightness are incompatible.

[0004] To achieve the above objectives, the main technical solutions adopted in this application include:

[0005] In a first aspect, embodiments of this application provide a vehicle headlight projection system, which includes a light source component, a reflector component, a DMD component, a projection component, and a deflector component. Light emitted from the light source component passes sequentially through the light source component, the reflector component, the DMD component, and the projection component. Along the light path of the headlight projection component, the deflector component is disposed downstream of the projection component, and light emitted from the projection component is emitted outward through the projection component. The deflector component is movable in a first direction to adjust the emission direction of the light emitted from the deflector component, and the first direction is perpendicular to the front-rear direction of the vehicle.

[0006] The vehicle headlight projection system proposed in this application has a folding component that is movable in a first direction, thereby adjusting the light emission direction of the folding component. This allows the headlight projection system to maintain high-intensity light illumination while expanding its illumination range.

[0007] Optionally, the first direction is the left and right direction of the vehicle, and the position of the folding component in the left and right direction of the vehicle is adjustable.

[0008] Because the position of the folding component is adjustable in the left and right directions of the vehicle, the headlight projection system can flexibly adjust the direction of the light projection, allowing the driver to shift the beam to the left or right as needed. This expands the illumination range of the headlight projection system without reducing the light intensity, thus adapting to different road conditions and driving needs.

[0009] Optionally, the first direction is the vertical direction of the vehicle, and the position of the folding component in the vertical direction of the vehicle is adjustable.

[0010] The tilting component is adjustable in the vertical direction of the vehicle, and the headlight projection system can dynamically adjust the beam height according to different road conditions and driving needs, expanding the beam range without reducing the beam intensity.

[0011] Optionally, the headlight projection system also includes a drive unit and a control unit, the control unit being adapted to receive steering information from the vehicle's steering wheel and control the drive unit to drive the turning assembly to move in a first direction based on the steering information.

[0012] By precisely controlling the movement of the folding components, the headlight projection system ensures that light always shines on the area that needs to be illuminated, avoiding light waste and blind spots, improving driving safety at night or in low light conditions, and also enhancing the driver's visual clarity.

[0013] Optionally, the folding assembly includes at least one folding lens.

[0014] The folding assembly includes at least one folding lens, which can be stacked according to the actual lighting needs of the vehicle, so that the light can cover a wider area after folding. This helps to provide the driver with a clearer vision and a wider lighting range at night or in low light conditions.

[0015] Secondly, this application provides a vehicle, which includes a vehicle body and a vehicle headlight projection system. The light source component, the reflector component, the DMD component, and the projection component are all fixedly mounted on the vehicle body, and the folding component is movably mounted on the vehicle body.

[0016] The deflector assembly is movably mounted on the vehicle body, which allows the headlight projection system to maintain high-intensity light illumination while expanding the vehicle's lighting range. When the deflector assembly remains stationary, the headlight projection system emits light within a preset light emission angle range, within which the light brightness is sufficient. Because the deflector assembly can move in a first direction, the illumination range of the light emitted by the headlight projection system increases, and the light emitted by the headlight projection system can also move in the first direction, thus ensuring both the brightness of the emitted light and a sufficient illumination range.

[0017] Optionally, the headlight projection system is a single system located at the front of the vehicle body.

[0018] The vehicle headlight projection system is a single unit located at the front of the vehicle body. The deflection component can be moved to change the angle of light emission and refraction, thereby expanding the vehicle's illumination range while maintaining the same light intensity.

[0019] Optionally, there are multiple vehicle headlight projection systems, including a first vehicle headlight projection system and a second vehicle headlight projection system; both the first vehicle headlight projection system and the second vehicle headlight projection system are located at the front end of the vehicle body, and the first vehicle headlight projection system and the second vehicle headlight projection system are spaced apart in the left and right directions of the vehicle.

[0020] Along the left and right directions of the vehicle, the first and second headlight projection systems are set at intervals, which can significantly widen the lighting area in front while ensuring the intensity of light illumination. This allows the driver to see the road and obstacles in front more clearly at night or in low light conditions, thus improving driving safety.

[0021] Optionally, the first vehicle headlight projection system has a first projection area projected onto the target surface, and the second vehicle headlight projection system has a second projection area projected onto the target surface, wherein the first projection area and the second projection area at least partially overlap.

[0022] The first projection area and the second projection area overlap at least partially, and the light from the first vehicle headlight projection system and the second vehicle headlight projection system will superimpose on each other, which can significantly enhance the lighting brightness of the superimposed area.

[0051] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0053] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0054] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" 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 direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0055] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0056] In this application, "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two), and "multiple pieces" refers to two or more (including two).

[0057] With the maturity and development of vehicle technology, the functions of vehicle lights are becoming increasingly powerful. Automotive lighting is evolving from traditional floodlighting to simultaneously incorporate ADB (Adaptive Driving Beam) and ground projection, resulting in a diversification of vehicle headlight projection technology.

[0058] Vehicle headlight projection systems can typically incorporate DMD (Digital Micro Mirror Element), Micro LED (Micro Light Emitting Diode), MEMS (Micro-Electro-Mechanical Systems), or LCoS (Large Reflective Liquid Crystal Display), etc.

[0059] Due to its advantages such as high brightness and low system complexity, the DMD (Digital Micromirror Device) is increasingly widely used in vehicle headlight projection systems. However, when a vehicle headlight projection system combines a lighting system, a DMD, and a projection lens for illumination, the brightness is insufficient when the illumination range is large, and conversely, high brightness is achieved with a small illumination range, creating a mismatch between a large illumination range and high brightness. In related technologies, to ensure both a large illumination range and high brightness, two DMD systems are often required, significantly increasing vehicle manufacturing costs.

[0060] In view of this, this application proposes a vehicle headlight projection system, which includes a light source assembly, a reflector assembly, a DMD assembly, a projection assembly, and a deflector assembly. The light emitted from the light source assembly passes sequentially through the light source assembly, the reflector assembly, the DMD assembly, and the projection assembly. Along the light path of the headlight projection assembly, the deflector assembly is disposed downstream of the projection assembly, and the light emitted from the projection assembly is emitted outward through the projection assembly. The deflector assembly is movable in a first direction to adjust the emission direction of the light emitted from the deflector assembly, and the first direction is perpendicular to the front-rear direction of the vehicle.

[0061] In the above scheme, the deflection component is movable in the first direction, thereby adjusting the light emission direction of the deflection component. This allows the vehicle headlight projection system to maintain high-intensity light illumination while expanding the illumination range of the vehicle headlight projection system.

[0062] The vehicle headlight projection system proposed in this application embodiment is not limited to use in vehicles, ships, or aircraft and other lighting equipment.

[0063] For ease of explanation, the following embodiments will be described using a vehicle headlight projection system and a vehicle according to an embodiment of this application as an example.

[0066] Please refer to Figures 1 to 5 In this embodiment, the vehicle headlight projection system 110 of the vehicle 100 includes a light source assembly 120, a reflector assembly 130, a DMD assembly 140, a projection assembly 150, and a deflector assembly 160. The light emitted from the light source assembly 120 passes sequentially through the light source assembly 120, the reflector assembly 130, the DMD assembly 140, and the projection assembly 150. Along the light path of the headlight projection assembly 150, the deflector assembly 160 is disposed downstream of the projection assembly 150, and the light emitted from the projection assembly 150 is emitted outward through the projection assembly 150. The deflector assembly 160 is movable in a first direction to adjust the emission direction of the light emitted from the deflector assembly 160, and the first direction is perpendicular to the front-rear direction X of the vehicle 100.

[0067] The light source assembly 120, as the name suggests, is a component for emitting light. For example, the light source assembly 120 may include an LED lamp and an illumination module. The LED lamp is used to emit LED light, and the illumination module is used to concentrate the light emitted by the LED lamp, thereby enhancing the light intensity of the LED.

[0068] The light emitted by the light source assembly 120 can pass through the reflector assembly 130, which can reflect the light emitted by the light source assembly 120 to the DMD assembly 140. When the light passes through the reflector assembly 130, the reflector assembly 130 can reshape the light that hits the reflector assembly 130, and the light can be adjusted according to the actual needs of the operation of the vehicle 100.

[0069] The DMD component 140 is a digital micromirror element and the core of DLP (Digital Light Processing) technology. Each DMD chip contains millions of tiny mirrors that can deflect or switch via electrostatic interaction to guide the direction of light. Each mirror can flip thousands of times per second, with extremely short response times and smooth switching, enabling high-precision light control. By precisely controlling the flip angle and frequency of each micromirror, the DMD component 140 can efficiently reflect light, achieving a high-brightness projection effect. The light reflected from the DMD component 140 can be used for vehicle 100 illumination, headlight projection, image generation, etc.

[0070] After being reflected from the DMD component 140, the light enters the projection component 150. The light can be focused and adjusted on the projection component 150. Depending on the specific application scenario, the light can be flexibly adjusted using the projection component 150.

[0071] The vehicle headlight projection system 110 also includes a deflector assembly 160. Light rays exiting the projection assembly 150 can enter the deflector assembly 160. The deflector assembly 160 can be located downstream of the projection assembly 150; for example, it can be positioned where the light rays exit the projection assembly 150. After the light rays enter and exit the deflector assembly 160, the incident and exit angles of the light rays change, meaning the light propagation path changes. This indicates that the light rays undergo refraction within the deflector assembly 160. However, the intensity of the light rays does not change after passing through the deflector assembly 160.

[0072] The deflector assembly 160 is movable along the first direction. As the deflector assembly 160 moves, light follows it, and the direction of light refraction is consistent with the direction of movement of the deflector assembly 160. For example, when the deflector assembly 160 moves along the first direction, the light is refracted in that direction. The first direction is perpendicular to the front-rear direction X of the vehicle 100, meaning that the deflector assembly 160 can move in any direction perpendicular to the plane of the vehicle 100, such as the left-right direction Y and the up-down direction Z.

[0073] The direction of movement of the deflector 160 can also be associated with the turning direction of the vehicle 100. When the vehicle 100 turns, for example, when the vehicle 100 needs to turn right, the deflector 160 can move to the right, thereby refracting the light to the right and illuminating the target area. Since the light does not change its divergence angle after passing through the deflector 160, the light can follow the deflector 160 as it moves along the first direction. This ensures that the light emitted by the headlight projection system 110 maintains high intensity while illuminating the target area as needed, thus expanding the illumination range. This eliminates the need to install multiple DMD components 140 on the vehicle 100, allowing the vehicle 100 to expand the illumination range at low cost and without reducing the light intensity.

[0074] Furthermore, due to the mobility of the folding component 160, the system can adapt to the needs of different vehicle models and body designs. Whether it's a sedan, SUV, or truck, optimal lighting effects can be achieved by adjusting the position and angle of the folding component 160 without requiring significant modifications or customization to the headlight projection system 110.

[0075] Specifically, the deflector assembly 160 is movable in the first direction, thereby adjusting the light emission direction of the deflector assembly 160. This allows the vehicle headlight projection system 110 to maintain high-intensity light illumination while expanding the illumination range of the vehicle headlight projection system 110.

[0076] Please refer to Figure 1 In this embodiment, the first direction is the left-right direction Y of the vehicle 100, and the position of the folding component 160 in the left-right direction Y of the vehicle 100 is adjustable.

[0077] When the deflector assembly 160 moves in the left-right direction Y of the vehicle 100, the light emitted from the deflector assembly 160 is also refracted in the direction of movement of the deflector assembly 160. For example, when the deflector assembly 160 moves to the left, the light emitted from the deflector assembly 160 is also refracted to the left, that is, the light will illuminate the target area on the left side of the vehicle 100. When the deflector assembly 160 moves to the right, the light emitted from the deflector assembly 160 is also refracted to the right, that is, the light will illuminate the target area on the right side of the vehicle 100.

[0078] Since the position of the deflector 160 in the Y direction of the vehicle 100 is adjustable, the headlight projection system 110 can flexibly adjust the projection direction of the light, allowing the driver to shift the illumination light to the left or right as needed. This expands the illumination range of the headlight projection system 110 without reducing the light intensity, thus adapting to different road conditions and driving needs.

[0079] Furthermore, adjusting the swivel assembly 160 around the vehicle's 100° position alters the beam's illumination range, allowing the driver to see road conditions and obstacles more clearly, thus improving reaction time and decision-making ability. By adjusting the position of the swivel assembly 160 in the Y-direction around the vehicle's 100° position, the beam's projection angle can be precisely controlled, thereby reducing glare to other road users, lowering the risk of traffic accidents, and improving road safety.

[0080] In some embodiments, the folding assembly 160 of the vehicle 100 can also be associated with the steering wheel of the vehicle 100. When the vehicle 100 turns left, the steering wheel is turned to the left, so that the light emitted from the folding assembly 160 will also be refracted to the left, that is, the light will illuminate the target area on the left side of the vehicle 100; when the vehicle 100 turns right, the steering wheel is turned to the right, so that the light emitted from the folding assembly 160 will also be refracted to the right, that is, the light will illuminate the target area on the right side of the vehicle 100. This allows the driver to observe the corresponding left or right area, improving the driving safety of the vehicle 100.

[0081] Please refer to Figure 1 For example, when the deflector assembly 160 is not moving, light is emitted from the deflector assembly 160 and illuminates the first area 170. When the deflector assembly 160 moves in the left-right direction Y of the vehicle 100, the light will be refracted in the deflector assembly 160. For example, when the deflector assembly 160 moves toward the right end of the vehicle 100, the direction of light refraction will also be refracted and moved toward the right side of the vehicle 100. This ensures that the intensity of the light emitted by the headlight projection system 110 is not weakened while expanding the illumination range of the light.

[0082] Please refer to Figure 2 In this embodiment, the first direction is the vertical direction Z of the vehicle 100, and the position of the folding component 160 in the vertical direction Z of the vehicle 100 is adjustable.

[0083] When the deflector assembly 160 moves in the vertical direction Z of the vehicle 100, the light emitted from the deflector assembly 160 is refracted in the direction of movement of the deflector assembly 160. For example, when the deflector assembly 160 moves upward, the light emitted from the deflector assembly 160 is refracted upward, meaning the light will illuminate the target area above the vehicle 100. When the deflector assembly 160 moves downward, the light emitted from the deflector assembly 160 is refracted downward, meaning the light will illuminate the target area below the vehicle 100. This allows the headlight projection system 110 to expand the illumination range of the light in the vertical direction Z of the vehicle 100 while ensuring the illumination intensity. For example, when the deflector assembly 160 is not moving, the light emitted from the deflector assembly 160 can illuminate the first area 170, and when the deflector assembly 160 moves in the vertical direction Z of the vehicle 100, the light can illuminate the second area 180.

[0084] The folding component 160 is adjustable in the Z-direction vertically of the vehicle 100. The headlight projection system 110 can dynamically adjust the beam height according to different road conditions and driving needs, expanding the beam range without reducing the beam intensity. For example, when driving on mountain roads or hilly areas, the beam may need to be adjusted upwards to illuminate the road ahead, while on city streets or flat highways, the beam may need to be adjusted downwards to avoid causing unnecessary glare to other road users.

[0085] Furthermore, by adjusting the position of the folding component 160 in the vertical Z direction of the vehicle 100, the distribution of light in the vertical direction can be precisely controlled. This is especially important for night driving or in poor visibility weather conditions, as it can help the driver see the road conditions and obstacles ahead more clearly.

[0086] In addition, when the folding component 160 moves downward, the refracted light also moves downward, and the light shines on the ground, which can project the desired static graphics and patterns on the ground closer to it, thus improving the user's comfort.

[0087] Please refer to Figures 1 to 5 In this embodiment, the vehicle headlight projection system 110 further includes a drive unit and a control unit. The control unit is adapted to receive steering information from the steering wheel of the vehicle 100 and control the drive unit to drive the turning assembly 160 to move in a first direction according to the steering information.

[0088] The drive component is used to drive the folding assembly 160 to move in a first direction. When the control unit receives steering information from the steering wheel of the vehicle 100, the steering information includes directions such as left, right, down, or up. The vehicle can include not only ground-based vehicles, but also flying cars, amphibious vehicles, etc.

[0089] For example, when the control unit receives steering information from the steering wheel of the vehicle 100, the control unit controls the drive component to drive the turning assembly 160 in the first direction, so that light can illuminate the area of ​​the vehicle 100 to be turned. Without reducing the light intensity, the illumination range of the light can be expanded, thereby improving the driving safety of the vehicle 100.

[0090] By precisely controlling the movement of the deflector assembly 160, the headlight projection system 110 can ensure that the light always shines on the area that needs to be illuminated, avoiding light waste and blind spots, improving driving safety at night or in low light conditions, and also enhancing the driver's visual clarity.

[0091] For example, when the driver turns the steering wheel to the left, it means that the vehicle 100 wants to drive to the left and the driver wants to observe the road conditions on the left. At this time, the control unit can control the turning assembly 160 to move to the left, and the light emitted by the headlight projection system 110 will move to the left to illuminate the road conditions on the left, thereby ensuring that the light shines on the places that need to be illuminated, improving practicality and safety.

[0092] When the driver turns the steering wheel to the right, it indicates that the vehicle 100 wants to drive to the right and the driver wants to observe the road conditions on the right. At this time, the control unit can control the turning assembly 160 to move to the right, and the light emitted by the headlight projection system 110 will move to the right to illuminate the road conditions on the right, thereby ensuring that the light shines on the places that need to be illuminated, improving practicality and safety.

[0093] Please refer to Figure 3 In some embodiments, the folding component 160 can also move toward the upper right of the vehicle 100. Before the folding component 160 moves, light shines on the first area 170. After the folding component 160 moves toward the upper right of the vehicle 100, light shines on the second area 180.

[0094] Please refer to Figures 1 to 5 In this embodiment, the folding assembly 160 includes at least one folding lens.

[0095] A refracting lens is used to refract and bend light. There can be one refracting lens. By properly designing the shape and angle of the refracting lens, the light can cover a wider area after being refracted. This helps to provide drivers with a clearer field of vision and a wider range of illumination at night or in low light conditions.

[0096] Multiple folding lenses can also be used. By stacking multiple folding lenses, the refractive index of the folding assembly 160 is enhanced, thereby expanding the range of light illumination.

[0097] Please refer to Figures 1 to 5 The projection assembly 150 includes a plurality of projection lenses 151, which are stacked along the light path of the vehicle headlight projection assembly 150.

[0098] The projection lens 151 can be used to focus or collect light sources. The stacked arrangement of multiple projection lenses 151 can more effectively collect and focus the light emitted by the light source assembly 120, reducing light loss during transmission. By precisely designing the shape and angle of each projection lens 151, it can be ensured that light is projected onto the deflection assembly in the best way, thereby improving light utilization.

[0099] In some embodiments, the deflection component can be integrated with the projection component 150, that is, the deflection component can be fixedly connected to the projection component 150. The deflection component can also be movably disposed at the light outlet of the projection component 150.

[0100] Please refer to Figures 1 to 15 This application also proposes a vehicle 100, which includes a vehicle body 101 and a vehicle headlight projection system 110. The light source assembly 120, the reflector assembly 130, the DMD assembly 140, and the projection assembly 150 are all fixedly disposed on the vehicle body 101, and the folding assembly 160 is movably disposed on the vehicle body 101.

[0101] The vehicle body 101 refers to the vehicle body excluding the headlight projection system 110. The folding assembly 160 is movably disposed on the vehicle body 101. The folding assembly 160 is movable in a first direction, thereby adjusting the light emission direction of the folding assembly 160. This allows the headlight projection system 110 to maintain high-intensity light illumination while expanding the illumination range of the vehicle 100.

[0102] When the deflection assembly 160 remains stationary, the light emitted by the vehicle headlight projection system 110 has a preset light emission angle range, within which the brightness of the light is sufficient. Since the deflection assembly 160 can move in the first direction, the illumination range of the light emitted by the vehicle headlight projection system 110 increases, and the light emitted by the vehicle headlight projection system 110 can also move in the first direction, thereby ensuring both the brightness of the emitted light and the sufficient illumination range of the light emitted by the vehicle headlight projection system 110.

[0103] Please refer to Figure 6In this embodiment, the vehicle headlight projection system 110 is a single system located at the front end of the vehicle body 101.

[0104] The headlight projection system 110 is a single unit. For example, the headlight projection system 110 can be located on the left side of the front end of the vehicle body 101, or it can be located on the right side of the front end of the vehicle body 101. When the vehicle 100 needs to turn, the deflection component 160 can be moved to change the emission and refraction angle of the light, thereby expanding the illumination range of the vehicle 100 while maintaining the same light intensity. When the vehicle 100 does not need to turn, the deflection component 160 does not move, and the light emitted by the headlight projection system 110 illuminates the corresponding illumination area 190 in front of the vehicle 100.

[0105] Please refer to Figure 7 For example, when vehicle 100 needs to turn left, the deflector assembly 160 can be moved to the left, thereby causing the light to refract to the left without changing the intensity of the light. The illumination range of the light is shifted to the left, making the driver's vision clearer and improving the driving safety of the driver of vehicle 100.

[0106] Please refer to Figure 8 For example, when vehicle 100 needs to turn right, the deflector assembly 160 can be moved to the right, thereby causing the light to refract to the right without changing the intensity of the light. The illumination range of the light is shifted to the right, making the driver's vision clearer and improving the driving safety of the driver of vehicle 100.

[0107] Please refer to Figure 9 and Figure 10 For example, when the folding component 160 of the vehicle 100 does not move, the distance between the illumination area 190 of the vehicle 100 and the front end of the vehicle 100 is a first illumination distance d1. When the folding component 160 of the vehicle 100 moves downward, the distance between the illumination area 190 of the vehicle 100 and the front end of the vehicle 100 is a second illumination distance d2. The first illumination distance d1 is greater than the second illumination distance d2, thereby enabling the free switching of the high and low beam headlights of the vehicle 100.

[0108] Please refer to Figures 11 to 15 In this embodiment, there are multiple vehicle headlight projection systems 110, including a first vehicle headlight projection system 111 and a second vehicle headlight projection system 112. The first vehicle headlight projection system 111 and the second vehicle headlight projection system 112 are both disposed at the front end of the vehicle body 101, and the first vehicle headlight projection system 111 and the second vehicle headlight projection system 112 are spaced apart in the left-right direction Y of the vehicle 100.

[0109] There can be multiple vehicle headlight projection systems 110, including a first vehicle headlight projection system 111 and a second vehicle headlight projection system 112. Along the longitudinal direction X of the vehicle 100, the first vehicle headlight projection system 111 and the second vehicle headlight projection system 112 are disposed in front of the vehicle 100. Along the left and right direction Y of the vehicle 100, the first vehicle headlight projection system 111 and the second vehicle headlight projection system 112 are disposed at intervals and can be located at both ends of the vehicle 100 in the left and right direction Y.

[0110] Along the left-right direction Y of the vehicle 100, the first headlight projection system 111 and the second headlight projection system 112 are arranged at intervals. While ensuring the intensity of light illumination, they can significantly widen the illumination area 190 in front, which allows the driver to see the road and obstacles in front more clearly at night or in low light conditions, thus improving driving safety.

[0111] Please refer to Figure 14 For example, the first headlight projection system 111 is located at the left end of the vehicle 100, and the second headlight projection system 112 is located at the right end of the vehicle 100. When the vehicle 100 turns right, the deflecting component 160 in the first headlight projection system 111 can move to the right and down of the vehicle 100, so that the light shines towards the lower front of the vehicle 100 and the right side of the vehicle 100, thereby enhancing the illumination of the vehicle 100. The deflecting component 160 in the second headlight projection system 112 can move to the right of the vehicle 100. Both the first projection area 111A and the second projection area 112A are projected onto the right side of the vehicle 100, thereby expanding the illumination range of the vehicle 100 while maintaining the light intensity.

[0112] Please refer to Figure 15 When vehicle 100 turns right, the deflection component 160 of the first headlight projection system 111 can move to the right, and the deflection component 160 of the second headlight projection system 112 can move to the right, thereby superimposing the illumination area 190 and enhancing the brightness of the illumination, thereby improving the visibility of vehicles 100 or pedestrians on the right and enhancing safety.

[0113] Please refer to Figures 11 to 15 The first vehicle headlight projection system 111 has a first projection area 111A projected onto the target surface, and the second vehicle headlight projection system 112 has a second projection area 112A projected onto the target surface. The first projection area 111A and the second projection area 112A at least partially overlap.

[0114] The first projection area 111A and the second projection area 112A overlap at least partially. The light from the first headlight projection system 111 and the second headlight projection system 112 will superimpose on each other. This superposition effect can significantly enhance the illumination brightness of the superimposed area, enabling the driver to see the road and obstacles ahead more clearly at night or in low light conditions.

[0115] Please refer to Figure 12 In some embodiments, the first projection area 111A and the second projection area 112A may not overlap, which can expand the illumination range of the vehicle 100 while ensuring a high illumination intensity.

[0116] Please refer to Figure 13 In some embodiments, the first projection area 111A and the second projection area 112A can completely overlap, resulting in a superimposed image, thereby achieving image overlap and increasing image brightness.
