Description

Technical Field

[0001] The present application relates to the field of vehicle lighting technology, and in particular to a vehicle light projection system and a vehicle. Background Art

[0002] With the maturity and development of vehicle technology, the functions of vehicle lighting are becoming more and more powerful. Automobile lighting has developed from traditional floodlighting to the direction of taking into account both ADB (Adaptive Driving Beam) and ground projection, and the vehicle headlight projection technology has become diversified. Due to the advantages of DMD (digital micromirror device) structure such as high brightness and low system complexity, DMD (digital micromirror device) is increasingly used in vehicle headlight projection systems. However, the vehicle headlight projection system uses a combination of lighting system, DMD (digital micromirror device) and projection lens for lighting. When the lighting range of the vehicle headlight projection system is large, the lighting brightness is insufficient, and when the lighting brightness is high, the lighting range is small. Large illumination range and high brightness are not compatible. Summary of the invention

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

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

[0005] In a first aspect, an embodiment of the present application provides a headlight projection system for a vehicle, wherein the headlight projection system for the vehicle comprises a light source assembly, a reflection assembly, a DMD assembly, a projection assembly and a folding assembly, wherein light emitted by the light source assembly passes through the light source assembly, the reflection assembly, the DMD assembly and the projection assembly in sequence; along the optical path of the headlight projection assembly, the folding assembly is arranged downstream of the projection assembly, and light emitted from the projection assembly is emitted outward via the projection assembly; wherein the folding assembly is movable in a first direction to adjust an emission direction of light emitted from the folding assembly, and the first direction is perpendicular to the front-rear direction of the vehicle.

[0006] The vehicle headlight projection system proposed in the embodiment of the present application has a folding component that is movable in a first direction, thereby being able to adjust the light emission direction of the folding component. This enables the headlight projection system to maintain high-intensity light irradiation on the one hand, and to expand the irradiation range of the headlight projection system on the other hand.

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

[0008] In this way, since the position of the folding component in the left and right directions of the vehicle is adjustable, the headlight projection system can flexibly adjust the projection direction of light, so that the driver can shift the irradiated light to the left or right as needed. While ensuring that the light intensity is not reduced, the irradiation range of the headlight projection system is expanded, thereby adapting to different road conditions and driving needs.

[0009] Optionally, the first direction is an up-down direction of the vehicle, and the position of the folding assembly in the up-down direction of the vehicle is adjustable.

[0010] The position of the folding component in the up and down directions of the vehicle is adjustable, and the headlight projection system can dynamically adjust the light irradiation height according to different road conditions and driving requirements, thereby expanding the light irradiation range while ensuring that the light irradiation intensity is not reduced.

[0011] Optionally, the vehicle light projection system further includes a driving member and a control unit, wherein the control unit is adapted to receive steering information of a steering wheel of the vehicle and control the driving member to drive the folding assembly to move in a first direction according to the steering information.

[0012] By precisely controlling the movement of the folding components, the headlight projection system can ensure 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 enhancing the driver's field of vision.

[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, which helps provide the driver with a clearer field of view and a wider lighting range at night or in low light conditions.

[0015] In the second aspect, an embodiment of the present application proposes a vehicle, which includes a vehicle body and a headlight projection system, wherein a light source component, a reflection component, a DMD component, and a projection component are all fixedly disposed on the vehicle body, and a folding component is movably disposed on the vehicle body.

[0016] The folding assembly is movably arranged on the vehicle body, so that on the one hand, the vehicle light projection system can maintain high-intensity light irradiation, and on the other hand, the vehicle lighting range can be expanded. When the folding assembly of the vehicle light projection system of the present application remains stationary, the light emitted by the vehicle light projection system has a preset light emission angle range, and within this angle range, the brightness of the light is sufficient; because the folding assembly can be moved in the first direction, the irradiation range of the light emitted by the vehicle light projection system becomes larger, and the light emitted by the vehicle light projection system can also be moved in the first direction, thereby ensuring the brightness of the emitted light and also ensuring that the light emitted by the vehicle light projection system has a sufficient irradiation range.

[0017] Optionally, there is one headlight projection system and it is arranged at the front end of the vehicle body.

[0018] The headlight projection system is a single unit located at the front end of the vehicle body. The turning assembly can be moved to change the emission and refraction angle of the light, thereby expanding the vehicle's lighting range while keeping the light intensity unchanged.

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

[0020] The first headlight projection system and the second headlight projection system are arranged at intervals along the left and right directions of the vehicle, which can significantly widen the front lighting area while ensuring the range of light intensity. This enables the driver to see the road and obstacles ahead more clearly at night or in low light conditions, thereby improving driving safety.

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

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

[0051] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0054] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "attached" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements.

[0055] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone.

[0056] The term "multiple" as used in this application refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple sheets" refers to more than two sheets (including two sheets).

[0057] With the maturity and development of vehicle technology, the functions of vehicle lighting are becoming more and more powerful. Automotive lighting has developed from traditional floodlighting to the direction of taking into account both ADB (Adaptive Driving Beam) and ground projection, and the vehicle-mounted headlight projection technology has become diversified.

[0058] The vehicle-mounted headlight projection system can usually be equipped with DMD (digital micromirror device), Micro LED (micro light emitting diode), MEMS (microelectromechanical system) or LCoS (small reflective liquid crystal display) and the like.

[0059] Since the DMD (digital micromirror device) structure has the advantages of high brightness and low system complexity, the application of DMD (digital micromirror device) in vehicle headlight projection systems is becoming more and more widespread. However, in the vehicle headlight projection system, a combination of a lighting system, a DMD (digital micromirror device) and a projection lens is used for lighting. When the lighting range of the vehicle headlight projection system is large, the lighting brightness is insufficient. When the lighting brightness is high and the lighting range is small, a large illumination range and high brightness are incompatible. In the related art, in order to ensure that the lighting brightness is high while the lighting range is large, two DMD systems need to be set up for use, which greatly increases the manufacturing cost of the vehicle.

[0060] In view of this, an embodiment of the present application proposes a headlight projection system for a vehicle, wherein the headlight projection system for the vehicle includes a light source assembly, a reflection assembly, a DMD assembly, a projection assembly and a folding assembly, wherein the light emitted by the light source assembly passes through the light source assembly, the reflection assembly, the DMD assembly and the projection assembly in sequence; along the light path of the headlight projection assembly, the folding assembly is arranged downstream of the projection assembly, and the light emitted from the projection assembly is emitted outward via the projection assembly; wherein the folding assembly is movable in a first direction to adjust the emission direction of the light emitted from the folding assembly, and the first direction is perpendicular to the front-rear direction of the vehicle.

[0061] In the above scheme, the folding component is movable in the first direction, so that the light emitting direction of the folding component can be adjusted, which can enable the vehicle light projection system to maintain high-intensity light irradiation on the one hand, and expand the irradiation range of the vehicle light projection system on the other hand.

[0062] The vehicle light projection system proposed in the embodiment of the present application is intended for but not limited to use in vehicles, ships, aircraft and other equipment requiring lighting.

[0063] For the convenience of description, the following embodiments are described by taking the vehicle light projection system and the vehicle according to one embodiment of the present application as an example.

[0066] Please refer to Figures 1 to 5 In this embodiment, the headlight projection system 110 of the vehicle 100 includes a light source assembly 120, a reflection assembly 130, a DMD assembly 140, a projection assembly 150 and a folding assembly 160. The light emitted by the light source assembly 120 passes through the light source assembly 120, the reflection assembly 130, the DMD assembly 140 and the projection assembly 150 in sequence. Along the optical path of the headlight projection assembly 150, the folding assembly 160 is arranged downstream of the projection assembly 150, and the light emitted from the projection assembly 150 is emitted outward through the projection assembly 150. The folding assembly 160 is movable in a first direction to adjust the emission direction of the light emitted from the folding 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 implies, is a component for emitting light. Exemplarily, the light source assembly 120 may include an LED lamp and a lighting module. The LED lamp is used to emit LED light, and the lighting 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 reflective assembly 130, and the reflective assembly 130 can reflect the light emitted by the light source assembly 120 to the DMD assembly 140. When the light passes through the reflective assembly 130, the reflective assembly 130 can shape the light irradiated on the reflective assembly 130, and the light can be adjusted according to the needs of the actual operation process of the vehicle 100.

[0069] The DMD component 140 is a digital micro-mirror element, and the DMD component 140 is the core of DLP (Digital Light Processing) technology. Each DMD chip contains millions of tiny lenses, which can be deviated or switched by electrostatic action to guide the direction of light. Each lens can flip thousands of times per second, with extremely short response time and smooth switching, which can achieve high-precision light control. The DMD component 140 can efficiently reflect light and achieve a high-brightness projection effect by precisely controlling the flipping angle and frequency of each micro-mirror. The light is reflected on the DMD component 140, and the reflected light can be used for lighting the vehicle 100, or for projection of the headlights of the vehicle 100 to generate images, etc.

[0070] After being reflected from the DMD component 140 , the light enters the projection component 150 , where it can be focused and adjusted. Depending on the specific usage scenario, the projection component 150 can be flexibly used to adjust the light.

[0071] The vehicle light projection system 110 further includes a folding assembly 160. After the light exits the projection assembly 150, it may enter the folding assembly 160. The folding assembly 160 may be disposed downstream of the projection assembly 150. Exemplarily, the folding assembly 160 may be disposed at the position where the light exits the projection assembly 150. After the light enters the folding assembly 160 and then exits the folding assembly 160, the incident angle and the exit angle of the light may change, that is, the propagation path of the light may change. It is understandable that the light is refracted in the folding assembly 160. After the light passes through the folding assembly 160, the intensity of the light will not change in the folding assembly 160.

[0072] The folding assembly 160 is movable along the first direction. When the folding assembly 160 moves, the light will follow the movement of the folding assembly 160, and the refraction direction of the light is consistent with the movement direction of the folding assembly 160. Exemplarily, when the folding assembly 160 moves along the first direction, the light will be refracted toward the first direction. The first direction is perpendicular to the front-rear direction X of the vehicle 100, that is, the folding assembly 160 can move in any direction perpendicular to the plane of the vehicle 100, such as the left-right direction Y, the up-down direction Z, etc.

[0073] The moving direction of the folding assembly 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 folding assembly 160 can move to the right, thereby refracting the light to the right, so that the light is irradiated to the target area. Since the light does not change its divergence angle when passing through the folding assembly 160, when the folding assembly 160 moves along the first direction, the light can move with the folding assembly 160, which can ensure that the light emitted by the headlight projection system 110 maintains high intensity while the light can be irradiated to the target area according to actual needs, thereby expanding the irradiation range of the light. There is no need to install multiple DMD assemblies 140 on the vehicle 100, so that the vehicle 100 can expand the irradiation range of the light at a low cost and without reducing the light intensity.

[0074] In addition, due to the mobility of the folding assembly 160, the system can adapt to the needs of different vehicle models and body designs. Whether it is a sedan, SUV or truck, the position and angle of the folding assembly 160 can be adjusted to achieve the best lighting effect without significantly modifying or customizing the headlight projection system 110.

[0075] Specifically, the folding assembly 160 is movable in a first direction, and thus the light emitting direction of the folding assembly 160 can be adjusted, which can enable the vehicle light projection system 110 to maintain high-intensity light irradiation on the one hand, and expand the irradiation range of the vehicle light projection system 110 on the other hand.

[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 assembly 160 in the left-right direction Y of the vehicle 100 is adjustable.

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

[0078] In this way, since the position of the folding component 160 in the left and right direction Y of the vehicle 100 is adjustable, the headlight projection system 110 can flexibly adjust the projection direction of the light, so that the driver can shift the irradiated light to the left or right as needed. While ensuring that the light intensity is not reduced, the irradiation range of the headlight projection system 110 is expanded, thereby adapting to different road conditions and driving needs.

[0079] In addition, by adjusting the folding assembly 160 to change the illumination range of the light on the left and right sides of the vehicle 100, the driver can see the road conditions and obstacles ahead more clearly, thereby improving the driver's reaction speed and decision-making ability. By adjusting the position of the folding assembly 160 in the left and right direction Y of the vehicle 100, the projection angle of the light can be accurately controlled, thereby reducing the glare effect on other road users, reducing the risk of traffic accidents, and improving road safety.

[0080] In some embodiments, the folding component 160 of the vehicle 100 can also be associated with the steering wheel of the vehicle 100. When the vehicle 100 turns left and the steering wheel is turned to the left, the light emitted from the folding component 160 will also be refracted toward 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 and the steering wheel is turned to the right, the light emitted from the folding component 160 will also be refracted toward 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, thereby improving the driving safety of the vehicle 100.

[0081] Please refer to Figure 1 Exemplarily, when the folding assembly 160 is not moving, light is emitted from the folding assembly 160 and illuminates the first area 170. When the folding assembly 160 moves in the left-right direction Y of the vehicle 100, the light will be refracted in the folding assembly 160. Exemplarily, when the folding assembly 160 moves toward the right end of the vehicle 100, the refraction direction of the light will also be refracted toward the right end of the vehicle 100. This can ensure 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 up-down direction Z of the vehicle 100 , and the position of the folding assembly 160 in the up-down direction Z of the vehicle 100 is adjustable.

[0083] When the folding assembly 160 moves in the up-down direction Z of the vehicle 100, the light emitted from the folding assembly 160 will also be refracted toward the moving direction of the folding assembly 160. For example, when the folding assembly 160 moves upward, the light emitted from the folding assembly 160 will also be refracted upward, that is, the light will irradiate the target area above the vehicle 100, and when the folding assembly 160 moves downward, the light emitted from the folding assembly 160 will also be refracted downward, that is, the light will irradiate the target area below the vehicle 100. In this way, the vehicle light projection system 110 can expand the irradiation range of the light in the up-down direction Z of the vehicle 100 while ensuring the irradiation intensity of the light. Exemplarily, when the folding assembly 160 does not move, the light emitted from the folding assembly 160 can irradiate the first area 170, and when the folding assembly 160 moves in the up-down direction Z of the vehicle 100, the light can irradiate the second area 180.

[0084] The position of the folding assembly 160 in the vertical direction Z of the vehicle 100 is adjustable, and the headlight projection system 110 can dynamically adjust the irradiation height of the light according to different road conditions and driving requirements, and expand the irradiation range of the light while ensuring that the irradiation intensity of the light is not reduced. For example, when driving on mountain roads or hilly areas, it may be necessary to adjust the light upward to illuminate the road conditions farther ahead, while when driving on city streets or flat roads, it may be necessary to adjust the light downward to avoid causing unnecessary glare to other road users.

[0085] Moreover, by adjusting the position of the folding assembly 160 in the up and down direction Z of the vehicle 100, the distribution of light in the vertical direction can be accurately controlled, which is particularly important for driving at night or in weather conditions with poor visibility, and can help the driver see the road conditions and obstacles ahead more clearly.

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

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

[0088] The driving member is used to drive the folding assembly 160 to move in a first direction. When the control unit receives the steering information of the steering wheel of the vehicle 100, the steering information includes the vehicle 100 turning left, right, downward or upward. The vehicle can include not only ground-moving vehicles, but also flying vehicles, amphibious vehicles, etc.

[0089] Exemplarily, when the control unit receives steering information from the steering wheel of the vehicle 100, the control unit controls the driving member to drive the folding assembly 160 in a first direction so that light can be irradiated to the area to be turned of the vehicle 100. Without reducing the light intensity, the irradiation range of the light can be expanded, thereby improving the driving safety of the vehicle 100.

[0090] By precisely controlling the movement of the folding assembly 160, the vehicle light projection system 110 can ensure that the light is always irradiated 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 enhancing the driver's field of vision.

[0091] For example, when the driver turns the steering wheel to the left, it means that the vehicle 100 wants to travel to the left, and the driver wants to observe the road conditions on the left. At this time, the control unit can control the folding assembly 160 to move to the left, and the light emitted by the car light projection system 110 will move toward the left to illuminate the road conditions on the left, thereby ensuring that the light is irradiated to the place that needs to be illuminated, thereby improving practicality and safety.

[0092] When the driver turns the steering wheel to the right, it means that the vehicle 100 wants to travel to the right, and the driver wants to observe the road conditions on the right side. At this time, the control unit can control the folding assembly 160 to move to the right, and the light emitted by the headlight projection system 110 will move toward the right to illuminate the road conditions on the right, thereby ensuring that the light is irradiated to the place that needs to be illuminated, thereby improving practicality and safety.

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

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

[0095] The folding lens is used to refract light. The folding lens can be one. By reasonably designing the shape and angle of the folding lens, the light can cover a wider area after being folded, which helps to provide the driver with a clearer field of vision and a wider lighting range at night or in low light conditions.

[0096] There may also be multiple folding lenses. By stacking multiple folding lenses, the refractive index of the folding assembly 160 is enhanced, thereby expanding the irradiation range of the light.

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

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

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

[0100] Please refer to Figures 1 to 15 The embodiment of the present application also proposes a vehicle 100, which includes a vehicle body 101 and a headlight projection system 110, wherein a light source assembly 120, a reflection assembly 130, a DMD assembly 140, and a 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 arranged on the vehicle body 101. The folding assembly 160 is movable in a first direction, and thus the light emitting direction of the folding assembly 160 can be adjusted. In this way, on the one hand, the headlight projection system 110 can maintain high-intensity light irradiation, and on the other hand, the lighting range of the vehicle 100 can be expanded.

[0102] When the folding assembly 160 of the vehicle light projection system 110 of the present application remains stationary, the light emitted by the vehicle light projection system 110 has a preset light emission angle range, within which the brightness of the light is sufficient; since the folding assembly 160 can move in the first direction, the irradiation range of the light emitted by the vehicle light projection system 110 becomes larger, and the light emitted by the vehicle light projection system 110 can also move in the first direction, thereby ensuring the brightness of the emitted light and also ensuring that the light emitted by the vehicle light projection system 110 has a sufficient irradiation range.

[0103] Please refer to Figure 6In this embodiment, the vehicle light projection system 110 is one and is disposed at the front end of the vehicle body 101 .

[0104] The headlight projection system 110 is one, and illustratively, the headlight projection system 110 can be arranged at the left side of the front end of the vehicle body 101, or the headlight projection system 110 can be arranged at the right side of the front end of the vehicle body 101. When the vehicle 100 needs to turn, the turning assembly can be moved to change the emission and refraction angle of the light, and the illumination range of the vehicle 100 can be expanded while keeping the light illumination intensity unchanged. When the vehicle 100 has no turning requirement, the turning assembly 160 does not move, and the light emitted by the headlight projection system 110 is directed to the front of the vehicle 100 to illuminate the corresponding illumination area 190.

[0105] Please refer to Figure 7 For example, when the vehicle 100 needs to turn left, the folding assembly 160 can be moved to the left, thereby refracting the light to the left. The intensity of the light does not change, and the irradiation range of the light shifts to the left, making the driver's field of vision clearer and improving the driving safety of the driver of the vehicle 100.

[0106] Please refer to Figure 8 For example, when the vehicle 100 needs to turn right, the folding assembly 160 can be moved to the right, thereby refracting the light to the right. The intensity of the light does not change, and the irradiation range of the light shifts to the right, making the driver's field of vision clearer and improving the driving safety of the driver of the vehicle 100.

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

[0108] Please refer to Figures 11 to 15 In the present embodiment, the vehicle light projection system 110 is multiple and includes a first vehicle light projection system 111 and a second vehicle light projection system 112; the first vehicle light projection system 111 and the second vehicle light projection system 112 are both arranged at the front end of the vehicle body 101, and the first vehicle light projection system 111 and the second vehicle light projection system 112 are spaced apart in the left-right direction Y of the vehicle 100.

[0109] There may be multiple headlight projection systems 110, including a first headlight projection system 111 and a second headlight projection system 112. Along the front-to-rear direction X of the vehicle 100, the first headlight projection system 111 and the second headlight projection system 112 are arranged in front of the vehicle 100. 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 and may be located at both ends of the vehicle 100 in the left-to-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, which can significantly widen the front lighting area 190 while ensuring the range of light illumination intensity. This allows the driver to see the road and obstacles ahead more clearly at night or in low light conditions, thereby improving driving safety.

[0111] Please refer to Fig.14 For example, the first headlight projection system 111 is arranged at the left end of the vehicle 100, and the second headlight projection system 112 is arranged at the right end of the vehicle 100. When the vehicle 100 turns right, the folding component 160 in the first headlight projection system 111 can move to the right and bottom of the vehicle 100, so that the light is irradiated toward the lower front of the vehicle 100 and the right side of the vehicle 100, thereby enhancing the lighting of the vehicle 100. The folding component 160 of the second headlight projection system 112 can move to the right side of the vehicle 100, and the first projection area 111A and the second projection area 112A are both projected on the right side of the vehicle 100, thereby expanding the lighting range of the vehicle 100 while maintaining the light illumination intensity.

[0112] Please refer to Fig.15 When the vehicle 100 turns right, the folding assembly 160 of the first headlight projection system 111 can move to the right, and the folding assembly 160 of the second headlight projection system 112 can move to the right, thereby overlapping the lighting area 190, enhancing the lighting brightness, thereby improving the recognizability of the vehicle 100 or pedestrians on the right side and enhancing safety.

[0113] Please refer to Figures 11 to 15 The first headlight projection system 111 has a first projection area 111A projected onto a target surface, and the second headlight projection system 112 has a second projection area 112A projected onto the target surface, and 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 at least partially overlap, and the light from the first headlight projection system 111 and the second headlight projection system 112 will overlap with each other. This superposition effect can significantly enhance the lighting brightness of the superimposed area, allowing the driver to see the road ahead and obstacles more clearly at night or in low light conditions.

[0115] Please refer to Fig.12 In some embodiments, the first projection area 111A and the second projection area 112A may not overlap, so that the lighting range of the vehicle 100 can be expanded while ensuring that the lighting intensity of the vehicle 100 is high.

[0116] Please refer to Fig.13 In some embodiments, the first projection area 111A and the second projection area 112A may completely overlap, and a superimposed image may appear, achieving frame overlap, thereby increasing picture brightness.
