Description

Technical Field

[0001] This application relates to the field of automotive lighting technology, specifically to a reflective component, a projection module, an automotive light, a control system, and a vehicle. Background Technology

[0002] In recent years, consumers have developed more personalized demands for projection devices on vehicles (such as vehicle lights), such as near-field welcome lighting, in-vehicle projection, and external projection. However, some display parameters of existing projection devices (such as focal length and field of view) are generally predetermined. In practical applications, the projection module is not easy to flexibly adjust its illuminated area, resulting in poor image display quality, or the illuminated area is not the area that the user needs, affecting the user experience. Utility Model Content

[0003] Embodiments of this application provide a reflective component, a projection module, a vehicle light, a control system, and a vehicle, which can be used to flexibly adjust the illuminated area of ​​the light source, thereby increasing the applicable scenarios of the projection module and improving the user experience.

[0004] In a first aspect, this application provides a reflective assembly, including a base, a rotating member, a first reflector, and a second reflector, wherein the first direction is the thickness direction of the body. The base includes a body and a mounting body. The body has a first light-transmitting hole that penetrates the body along the first direction. The mounting body is connected to the body and is arranged around the first light-transmitting hole. The inner circumferential surface of the mounting body forms a receiving cavity that communicates with the first light-transmitting hole.

[0005] The rotating component is provided with a second light-transmitting hole, which passes through the rotating component along the first direction. The rotating component is connected to the mounting body, and the second light-transmitting hole is connected to the receiving cavity. The second light-transmitting hole is used to allow light from the light source to pass through. The rotating component can rotate relative to the mounting body, and the central axis of rotation is the center line of the first light-transmitting hole.

[0006] A first reflector is connected to the rotating member and is located within the propagation path of the light from the light source. A second reflector is connected to the rotating member and is spaced apart from the first reflector. The second reflector is capable of reflecting the light propagated through the first reflector.

[0007] Currently, reflective components can be used to reflect light from a light source, thereby illuminating different areas in different application scenarios and providing lighting services to users under various conditions. To adjust the illuminated area of ​​the light source, a transmission component is generally used to change the angle of the light source, thereby changing the path of the light and thus altering the illuminated area.

[0008] Because of the large size of the light source, it requires a considerable amount of space to move during rotation. However, the space available for installing light sources on typical vehicles is limited. Therefore, the movement of the light source is restricted by the installation space, preventing large-angle adjustments and thus limiting its field of view.

[0009] In this embodiment, when it is necessary to adjust the illuminated area of ​​the light source, the rotating member can be rotated relative to the mounting body to change the position of the first reflector and the second reflector relative to the light source, thereby changing the propagation path of the light from the light source and thus changing the illuminated area of ​​the light source.

[0010] The first and second reflectors can be any reflective plane mirror, etc. The volume of the first and second reflectors is much smaller than that of the light source. Therefore, when the rotating part rotates, the space required for the first and second reflectors to move is small. The first and second reflectors can make large angle changes (the angle between the reflector and the light from the light source) in a limited space, thereby changing the illuminated area to a greater extent, and thus allowing the illuminated area of ​​the light source to vary within a larger range.

[0011] The first reflector can reflect the light from the light source toward the second reflector. The second reflector can change the direction of light propagation after passing through the first reflector, deflecting the light closer to the vehicle body, so that the light can reach an area closer to the vehicle body, thereby expanding the field of view of the light source.

[0012] 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.

[0013] When a vehicle is in motion, the light emitted by the light source passes through the first and second reflectors, creating a light carpet effect. 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.

[0014] The reflective component can also rotate in real time to meet various new scenario requirements such as mobile projection and projection of auxiliary lane lighting signals.

[0015] In one possible implementation, the reflective assembly is provided with a first driving member, one end of which is fixedly connected to the rotating member, and the other end of which contacts the mounting body and is used to roll on the outer surface of the mounting body. The first driving member is used to drive the rotating member to rotate relative to the mounting body.

[0016] In this embodiment, the first driving member enables the rotating member to rotate relative to the mounting body, thereby driving the first reflector and the second reflector to rotate relative to the light source, so as to change the illuminated area of ​​the light source.

[0017] In one possible implementation, the first reflector is rotatably connected to the rotating member, and the central axis of rotation of the first reflector is a straight line in the second direction, which is different from the first direction.

[0018] In this embodiment, the rotation direction of the first reflector is different from that of the rotating member, so that the angle of the first reflector can change in different directions, thereby allowing the propagation direction of the light from the light source to change flexibly in different directions, thus expanding the field of view of the light source.

[0019] Since the rotating component can drive the first reflector and the second reflector to rotate simultaneously, the relative position of the first reflector and the second reflector changes little. The second reflector can remain within the path of the light reflected by the first reflector, preventing the light reflected by the first reflector from failing to reach the second reflector due to the first reflector moving, thus causing the second reflector to lose its function of changing the light path.

[0020] In one possible implementation, the reflective component includes a first projection mode and a second projection mode;

[0021] When the reflective component is in the first projection mode, the reflective surface of the first reflector is parallel to the straight line containing the first direction;

[0022] When the reflective component is in the second projection mode, the angle between the reflective surface of the first reflector and the straight line containing the first direction is an acute angle, and the reflective surface of the first reflector is opposite to the reflective surface of the second reflector.

[0023] In this embodiment, when the reflective surface of the first reflector is parallel to the straight line containing the first direction, the light emitted by the light source can propagate directly to the outside of the reflective assembly without passing through the reflective surface of the first reflector. In this case, the reflective assembly can be a low beam or high beam, etc., of a vehicle headlight.

[0024] When the angle between the reflective surface of the first reflector and the straight line containing the first direction is acute, the light emitted by the light source will be reflected on the surface of the first reflector, thereby changing the propagation direction. At this time, the illuminated area can be a near-field welcome mode for vehicle headlights.

[0025] In one possible implementation, the rotating member includes a first part and a second part connected together, a second light-transmitting hole penetrating the first part and the second part along a first direction, the first part being sleeved on the outer periphery of the mounting body, and the outer peripheral surface of the second part being recessed relative to the outer peripheral surface of the first part. A first reflector and a second reflector are connected to the outer peripheral surface of the second part.

[0026] In this embodiment, the first part can be fitted onto the outer periphery of the mounting component, allowing the inner circumferential surface of the first part to slide relative to the outer circumferential surface of the mounting component. The outer circumferential surface of the second part is recessed relative to the outer circumferential surface of the first part, providing mounting positions for the first and second reflectors. The recessed space between the outer circumferential surface of the second part and the outer circumferential surface of the first part provides mounting space for the first and second reflectors, improving the space utilization of the reflective assembly.

[0027] In one possible implementation, the first driving component includes a first motor, a first rotating shaft, and a first transmission structure. The first motor is fixedly connected to a first part, one end of the first rotating shaft is rotatably connected to the first motor, and the other end passes through the first part and is connected to the end face of the first transmission structure. The peripheral surface of the first transmission structure contacts the outer peripheral surface of the mounting body.

[0028] In this embodiment, the first motor can automatically rotate the rotating component. The high-precision control capability of the motor ensures that the first rotating wheel moves at a predetermined speed when the first transmission structure rotates, thereby making the rotation angle of the rotating component relative to the mounting body more accurate, so as to make the positioning of the illuminated area of ​​the light source more accurate and improve the user experience.

[0029] In one possible implementation, the reflective assembly includes a second driving member mounted on the outer peripheral surface of the rotating component. The rotating component has a first shaft hole extending through it along a second direction. The first reflector includes a reflective body and a shaft. The reflective body is connected to the periphery of the shaft, which extends along the second direction and passes through the first shaft hole. The second driving member is capable of driving the shaft to rotate.

[0030] The second reflector is fixed relative to the rotating component.

[0031] In one possible implementation, the second driving component includes a second motor, a second rotating shaft, and a second transmission structure. The second motor is fixedly connected to the outer peripheral surface of the rotating component, one end of the second rotating shaft is rotatably connected to the second motor, and the other end is connected to the end face of the second transmission structure.

[0032] The projection device also includes a third transmission structure, which is sleeved on the end of the shaft and meshes with the second transmission structure.

[0033] In one possible implementation, the rotating member is provided with a mounting notch, which is recessed from the end face of the rotating member away from the body, and the mounting notch is opposite to the first shaft hole in the second direction.

[0034] The shaft includes a first end and a second end, which are opposite to each other in a second direction. The first end passes through a first shaft hole and is connected to the third transmission structure. At least a portion of the second end is located within a mounting notch.

[0035] In this embodiment, during assembly, the first end of the first reflector can be inserted into the first shaft hole first. Then, the second end is installed into the mounting notch, thereby connecting the first reflector to the rotating member.

[0036] In one possible implementation, the reflection component further includes a damping component, which includes a mounting base and a damping body. The mounting base is connected to the outer surface of the rotating component. The mounting base has a second shaft hole that extends through the mounting base in a second direction and communicates with a mounting notch. A second end is inserted through the second shaft hole, and the damping body is connected to the second end and located on the side of the mounting base away from the mounting notch.

[0037] In this embodiment, when the first reflector is subjected to an external force, the damping body generates a reverse torque. When the magnitude of the external force is less than the magnitude of the damping force, the first reflector does not rotate, thereby reducing the swaying of the first reflector when no angle adjustment is required, which affects the swaying of the illumination position of the light source. When the magnitude of the external force is greater than the damping force, the first reflector can rotate, thereby stably adjusting the illumination area of ​​the light source and stably switching the user's usage scenario.

[0038] Secondly, this application also provides a projection module, including a light source and a reflection component as described above. The light source is connected to the body, and at least part of the light source is located in the first light-transmitting hole and the receiving cavity. The light from the light source can propagate along the first direction to the second light-transmitting hole.

[0039] Thirdly, this application provides a vehicle lamp, including a lamp housing and a projection module as described above, wherein the lamp housing has a receiving space and the projection module is installed in the receiving space.

[0040] Fourthly, this application also provides a control system, including a controller and the reflective assembly as described above, wherein the controller is capable of controlling the rotating component to drive the first reflective component and the second reflective component to move.

[0041] Fifthly, this application also provides a vehicle, including a vehicle body, a controller, a light source, and a reflective component as described above. The controller, the light source, and the reflective component are all mounted on the vehicle body. The controller can control the rotating component to drive the first reflective component and the second reflective component to move, thereby changing the propagation path of the light from the light source.

[0061] The specific embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can also be implemented in other ways different from those described herein. Therefore, the present application is not limited by these embodiments.

[0062] For the convenience of understanding, the terms involved in the embodiments of the present application are first explained.

[0063] Multiple: It means two or more than two.

[0064] Connection: It should be understood in a broad sense. For example, if A is connected to B, it can be that A is directly connected to B, or A is indirectly connected to B through an intermediate medium.

[0065] The specific embodiments of the present application will be clearly described below with reference to the accompanying drawings.

[0066] The embodiments of the present application provide a vehicle. It can flexibly adjust the projection area of the projection module, expand the viewing field of the projection module, and achieve a larger range of lighting and projection.

[0067] Please refer to Figure 1 and Figure 2 , Figure 1 is the structural schematic diagram of the vehicle 1000 provided by the embodiments of the present application. Figure 2 is Figure 1 The partial structural schematic diagram of the vehicle lamp 100 shown. Figure 1The Y direction shown is the width direction of vehicle 1000, and the Y direction is the direction in which vehicle 1000 faces to the right. Figure 1 The X direction shown is the length direction of vehicle 1000, and the X direction is the direction in which vehicle 1000 faces forward. Figure 1 The Z-direction shown represents the height direction of vehicle 1000, and is the direction in which vehicle 1000 faces upwards. For ease of description, the X-direction is defined as the first direction, the Y-direction as the second direction, and the Z-direction as the third direction.

[0068] In this application, the vehicle 1000 can be a known vehicle such as a car, airplane, ship, or rocket, or a new type of vehicle that may emerge 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 this. The following description uses a vehicle 1000 as an example.

[0069] The vehicle 1000 includes a projection module 10, a controller 20, and a vehicle body 200. The projection module 10 and the controller 20 are mounted on the vehicle body 200. The controller 20 can be electrically connected to the projection module 10. The controller 20 can control the projection module 10 to adjust the direction of light propagation of the light source emitted by the projection module 10.

[0070] 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 projection module 10 to control the projection module 10 to adjust the direction of light propagation to achieve the desired lighting effect. It should be noted that, with technological advancements, the controller 20's functions may be integrated into the vehicle's computer system, allowing the computer system to directly control the projection module 10 to change the direction of light propagation. For example, the controller 20 could be integrated into the cockpit domain controller 20. This application does not limit the specific operating method of the controller 20.

[0071] The projection module 10 and controller 20 can be parts of the headlight 100 of the vehicle 1000. The headlight 100 can include light-emitting components such as the projection module 10, low beam headlights, and high beam headlights. The projection module 10 of the headlight 100 will be described in detail below.

[0072] It should be noted that, in addition to being a vehicle lamp module within the vehicle lamp 100, the projection module 10 can also be any device capable of illumination or image projection. The light projected by the projection module 10 can be monochromatic light, colored light, or image light capable of displaying patterns, etc. This application does not limit the type of light emitted by the projection module 10.

[0073] The vehicle light 100 can be an external or internal light fixture on a vehicle. For example, the vehicle light 100 may also include a lamp housing (not shown). The lamp housing has a receiving space. The lamp housing may cover the projection module 10. The vehicle light 100 may also integrate some sensing modules, for example, integrating any of the sensing modules such as lidar, millimeter-wave radar, or infrared detection devices into the vehicle light 100 to form an integrated sensing and illumination vehicle light 100.

[0074] 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.

[0075] 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.

[0076] 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 lamps 100, ensuring the quality and performance of the lamps 100 by detecting gas leakage between the lamp housing and the bulb.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] In recent years, with the rapid development of electric vehicles, the importance and practical value of vehicle intelligence have become increasingly prominent. At the same time, consumers have 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 suffers from limitations in pattern variety and a narrow field of view, restricting the welcome range of the lights. Similarly, in the light carpet scenario, the field of view is also limited, generally only covering one lane ahead, suitable only for indicating lane width, with very limited illumination in more critical scenarios such as lane changes and turns.

[0081] Based on this, this application provides a projection module 10 that can flexibly adjust the illuminated area of ​​the light source, thereby increasing the applicable scenarios of the projection module 10, such as curve lighting, turning light carpet, ramp lighting, large-scale welcoming and other new scenarios, and improving the user experience.

[0082] Please refer to the following: Figure 2 and Figure 3 , Figure 3 yes Figure 2 The exploded view of the projection module 10 shown includes a reflective component (not shown) and a light source 13. The light source 13 is connected to the reflective component. The reflective component is used to change the direction of light propagation from the light source 13, thereby flexibly adjusting the illuminated area of ​​the light source 13.

[0083] The reflective assembly includes a base 11, a rotating member 12, a first reflector 14, and a second reflector 15. The rotating member 12 is rotatably connected to the base 11. The base 11 is connected to a light source 13, and the light beam from the light source 13 can be emitted through the base 11 and the rotating member 12. The first reflector 14 and the second reflector 15 are connected to the rotating member 12. The rotating member 12 can drive the first reflector 14 and the second reflector 15 to rotate, and the first reflector 14 and the second reflector 15 are used to change the propagation direction of the light beam from the light source 13, thereby changing the illuminated area of ​​the projection module 10.

[0084] It should be noted that, Figure 2 The purpose of this illustration is merely to depict the connection relationship between the base 11, rotating member 12, light source 13, first reflector 14, and second reflector 15, 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 projection module 10. In other embodiments of this application, the projection module 10 may include more or fewer components than illustrated, or combine certain components, or split certain components, or have different component arrangements.

[0085] Please see Figure 4 , Figure 4 yes Figure 3The diagram shows the structure of the base 11. The base 11 includes a body 111 and a mounting body 112. The mounting body 112 is connected to the body 111 and provides a mounting position for the rotating component 12. When the base 11 is mounted on the vehicle body, the body 111 is used to fix it to the vehicle body 200.

[0086] The main body 111 is provided with a first light-transmitting hole 1110, which penetrates the main body 111 along the X direction. For example, the main body 111 may also be provided with a plurality of reinforcing ribs 1111, which can be connected to the surface of the main body 111 facing the X direction.

[0087] In this embodiment, the reinforcing rib 1111 increases the load-bearing capacity of the body 111, enabling it to better resist external forces such as tension, compression, and bending. By rationally arranging the reinforcing ribs 1111, the stress on the body 111 can be effectively dispersed and transferred, preventing stress concentration from causing structural damage to the body 111. The structural form of the reinforcing rib 1111 is not limited.

[0088] Mounting body 112 is connected to the surface of body 111 facing the X direction. Mounting body 112 is disposed around the first light-transmitting hole 1110. The inner peripheral surface of mounting body 112 forms a receiving cavity 1120, which communicates with the first light-transmitting hole 1110.

[0089] The outer surface of the mounting body 112 is also provided with a limiting protrusion 1121, a limiting groove 1122, and a sliding groove 1123. Both the limiting protrusion 1121 and the limiting groove 1122 are arranged around the mounting body 112. The limiting protrusion 1121 protrudes from the outer peripheral surface of the mounting body 112. The limiting groove 1122 is recessed from the outer peripheral surface of the mounting body 112. The limiting groove 1122 is located on the side of the limiting protrusion 1121 opposite to the main body 111, and the limiting groove 1122 and the limiting protrusion 1121 are spaced apart in the X direction. The limiting groove 1122 is closer to the first light-transmitting hole 1110 than the limiting protrusion 1121.

[0090] The sliding groove 1123 is recessed from the outer peripheral surface of the mounting body 112. The sliding groove 1123 is adjacent to the limiting groove 1122. The sliding groove 1123 extends circumferentially along the mounting body 112. The sliding groove 1123 penetrates the end face of the mounting body 112 opposite to the main body 111. Exemplarily, the sliding groove 1123 may surround the mounting body 112 for a full circumference. Alternatively, the sliding groove 1123 may surround half of the mounting body 112 and be located on the side of the mounting body 112 facing the opposite direction to the Z direction. This application embodiment does not limit the length of the sliding groove 1123.

[0091] Please refer to the following: Figure 3 The rotating component 12 can be cylindrical. The rotating component 12 is provided with a second light-transmitting hole 120. The second light-transmitting hole 120 passes through the rotating component 12 along the X direction.

[0092] The rotating component 12 is connected to the mounting body 112, the second light-transmitting hole 120 is connected to the receiving cavity 1120, the rotating component 12 can rotate relative to the mounting body 112, and the central axis of rotation is the center line a of the first light-transmitting hole 1110.

[0093] The rotating member 12 can be sleeved on the outer periphery of the mounting body 112. Alternatively, the rotating member 12 can be located in the receiving cavity 1120 of the mounting body 112. This application embodiment does not limit the nesting relationship between the rotating member 12 and the mounting body 112. The following description assumes that the rotating member 12 is sleeved on the outer periphery of the mounting body 112, but it should be understood that this is not a limitation.

[0094] Please see Figure 5 , Figure 5 yes Figure 3 The diagram shows the structure of the rotating component 12. The rotating component 12 includes a first part 121 and a second part 122 connected together. A second light-transmitting hole 120 passes through the first part 121 and the second part 122 along the X direction.

[0095] Please refer to the following: Figure 5 and Figure 6 , Figure 6 yes Figure 3 The diagram shows a cross-sectional view of the connection between the base 11 and the rotating component 12. A first portion 121 is fitted onto the outer periphery of the mounting body 112. The first portion 121 has a first connecting hole 1211, a first bearing groove 1212, and a first washer groove 1213. The first connecting hole 1211 penetrates the first portion 121 along the X-direction. The first bearing groove 1212 is recessed by the hole wall of the first connecting hole 1211 in the first portion 121 and penetrates the surface of the first portion 121 in the opposite direction to the X-direction. The first bearing groove 1212 surrounds the inner circumferential surface. The first washer groove 1213 is recessed by the bottom wall of the first bearing groove 1212. The first washer groove 1213 surrounds the bottom wall of the first bearing groove 1212.

[0096] For example, the first portion 121 further includes a protrusion 1214. The protrusion 1214 is connected to the end face of the first portion 121 facing the X direction. The protrusion 1214 has a second connecting hole 1215. The second connecting hole 1215 passes through the protrusion 1214. The second connecting hole 1215 communicates with the first connecting hole 1211.

[0097] In this embodiment, the first part 121 can be sleeved on the outer periphery of the mounting body 112 so that the inner peripheral surface of the first part 121 can slide relative to the outer peripheral surface of the mounting body 112.

[0098] The second part 122 is connected to the end face of the first part 121 facing the X direction. The outer peripheral surface of the second part 122 is recessed relative to the outer peripheral surface of the first part 121. The second part 122 is provided with a first shaft hole 1221 and a mounting notch 1222. The first shaft hole 1221 penetrates the inner and outer peripheral surfaces of the second part 122 along the Y direction. The mounting notch 1222 is recessed from the end face of the second part 122 away from the first part 121 and penetrates the inner and outer peripheral surfaces of the second part 122. The first shaft hole 1221 and the mounting notch 1222 communicate with the second light-transmitting hole 120. The first shaft hole 1221 and the mounting notch 1222 are spaced apart from each other in the Y direction.

[0099] For example, the second part 122 further includes a second motor limiting body 1223, a damping limiting body 1224, and a second reflector limiting body 1225. The second motor limiting body 1223, the damping limiting body 1224, and the second reflector limiting body 1225 are all connected to the outer peripheral surface of the second part 122. The second motor limiting body 1223, the damping limiting body 1224, and the second reflector limiting body 1225 are used to connect with other components of the projection module 10.

[0100] Specifically, the second motor limiting body 1223 is connected to the side of the second part 122 facing the Y direction, and the second motor limiting body 1223 is located at the periphery of the first shaft hole 1221. The second motor limiting body 1223 is provided with a limiting hole 1223a. The limiting hole 1223a passes through the second motor limiting body 1223 along the X direction.

[0101] A damping element limiter 1224 is connected to the side of the second portion 122 facing the opposite direction of the Y direction. The damping element limiter 1224 is located around the periphery of the mounting notch 1222. Exemplarily, the number of damping element limiters 1224 can be three. The three damping element limiters 1224 are spaced apart around the periphery of the mounting notch 1222.

[0102] The second reflector limiting body 1225 is connected to the side of the second part 122 facing the Z direction. The second reflector limiting body 1225 extends in the Z direction. For example, there are two second reflector limiting bodies 1225, and the two second reflector limiting bodies 1225 are spaced apart in the Y direction.

[0103] For some possible implementation methods, please refer to the following references. Figure 3 and Figure 6 The projection module 10 also includes a first bearing 16, a first washer 17, and a second washer 18. The first bearing 16, the first washer 17, and the second washer 18 are all fitted around the outer periphery of the mounting body 112.

[0104] A portion of the first washer 17 is connected to the groove wall of the first washer groove 1213. The inner ring portion of the first washer 17 protrudes relative to the first washer groove 1213, and the inner ring portion of the first washer 17 contacts the surface of the first bearing 16 in the opposite direction to the X direction.

[0105] The inner ring of the first bearing 16 is fitted onto the outer periphery of the mounting body 112. The outer ring of the first bearing 16 is connected to the groove wall of the first bearing groove 1212 of the first part 121. The side of the inner ring of the first bearing 16 facing the opposite direction of the X direction contacts the limiting protrusion 1121 of the mounting body 112.

[0106] The inner ring portion of the second washer 18 is connected within the limiting groove 1122. The outer ring portion of the second washer 18 contacts the X-direction-facing side of the inner ring of the first bearing 16.

[0107] In this embodiment, the first bearing 16 can support the rotational movement of the rotating component 12, reducing friction and wear between the inner circumferential surface of the first portion 121 and the outer circumferential surface of the mounting body 112. This ensures efficient and stable operation of the rotational movement of the first portion 121. The gap between the first washer 17 and the second washer 18 can accommodate the first bearing 16, preventing the bearing from wobbling between the first portion 121 of the rotating component 12 and the outer surface of the mounting body 112.

[0108] The light source 13 is connected to the body 111 of the base 11. At least part of the light source 13 is located within the first light-transmitting hole 1110 and the receiving cavity 1120. The light from the light source 13 can propagate in the X direction through the second light-transmitting hole 120.

[0109] Specifically, the light source 13 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.

[0110] Currently, projection modules need to illuminate different areas in different usage scenarios to provide lighting services to users under various conditions. To adjust the illuminated area of ​​the projection module, a drive wheel is typically used to change the angle of the light source, thereby altering the path of the light and thus changing the illuminated area. Because the light source is relatively large, it requires considerable space to move during rotation. However, the space available for installing projection modules in typical vehicles is limited, thus restricting the movement of the light source and limiting its angle, resulting in a limited field of view for the projection module.

[0111] Therefore, this application embodiment provides a method of setting a first reflector 14 and a second reflector 15 to change the propagation direction of the light from the light source 13, thereby changing the illumination position of the projection module 10, so that the illumination position of the projection module 10 can be flexibly adjusted, thereby expanding the field of view of the projection module 10.

[0112] Please see Figure 7 , Figure 7 yes Figure 3 The diagram shows the structure of the first reflector 14. The first reflector 14 includes a first support 141, a first mirror body 142, and a first cover 143. The first support 141 and the first cover 143 form a receiving space. The first mirror body 142 is located within this receiving space.

[0113] Specifically, the first support 141 includes a support body 1411 and a shaft 1412.

[0114] The shaft 1412 is connected to the bracket body 1411. When the shaft 1412 rotates, the position of the side of the bracket body 1411 away from the shaft 1412 changes significantly.

[0115] The shaft 1412 extends along the Y direction. The shaft 1412 includes a first end 1412a and a second end 1412b. The first end 1412a and the second end 1412b are opposite to each other in the Y direction. For example, the first end 1412a and the second end 1412b can be opposite ends of the same rod, or the first end 1412a and the second end 1412b can be directly connected to the support body 1411, and there may be no rod between the first end 1412a and the second end 1412b. In this embodiment, the central axes of the first end 1412a and the second end 1412b of the shaft 1412 only need to coincide; the specific shape of the shaft 1412 is not limited.

[0116] The first end 1412a and the second end 1412b of the shaft 1412 protrude relative to the support body 1411.

[0117] A first cover 143 covers the periphery of the surface of the first mirror 142 facing away from the support body 1411. The first cover 143 is connected to the periphery of the support body 1411. The first cover 143 and the support body 1411 can form a receiving space for the first mirror 142 to be installed. The first cover 143, the first mirror 142, and the support body 1411 together form the reflective body 111 of the first reflector 14. The first mirror 142 is connected to one side of the support body 1411. The surface of the first mirror 142 facing away from the support body 1411 is the reflective surface of the first reflector 14.

[0118] Please see Figure 8 , Figure 8 yes Figure 3 The diagram shows the assembly of the first reflector 14 and the rotating member 12. The first reflector 14 is mounted on the second part 122 of the rotating member 12. The first end 1412a of the first bracket 141 passes through the first shaft hole 1221. At least part of the second end 1412b is located within the mounting notch 1222.

[0119] During assembly, the first reflector 14 can be first inserted into the first shaft hole 1221. Then, the second end 1412b is installed in the mounting notch 1222, thereby connecting the first reflector 14 with the rotating member 12, and thus placing the first reflector 14 within the propagation path of the light from the light source 13.

[0120] In this embodiment, the position of the light source 13 of the projection module 10 can be fixed relative to the base 11. When it is necessary to adjust the illuminated area of ​​the projection module 10, the angle of the first reflector 14 can be adjusted to change the propagation path of the light from the light source 13, thereby changing the illuminated area of ​​the projection module 10. The first reflector 14 can be any reflective plane mirror, etc. The volume of the first reflector 14 is much smaller than the volume of the light source 13. Therefore, the space required for the first reflector 14 to rotate is small, and the first reflector 14 can make a large angle change in a limited space, thereby changing the illuminated area to a greater extent, so that the illuminated area of ​​the projection module 10 can vary within a large range.

[0121] The first reflector 14 can change its angle in the light path of the light source 13, thereby changing the propagation direction of the light passing through the first reflector 14. It can deflect the light closer to the vehicle body 200, so that the light passing through the first reflector 14 can reach the area closer to the vehicle body 200, thereby expanding the field of view of the projection module 10.

[0122] 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.

[0123] When the vehicle 1000 is in motion, the light emitted by the light source 13 can form a light carpet effect after passing through the first reflector 14. The turning light carpet can predict the vehicle's driving path in real time. When the vehicle is about to change lanes or turn, the light carpet will bend accordingly, thus clearly indicating the vehicle's driving intention. This not only helps the driver better grasp the vehicle's dynamics, but also allows surrounding pedestrians and vehicles to react in advance, avoiding collisions.

[0124] The projection module 10 can also adjust the distance and left and right in real time to move the light, or project auxiliary lane lights and other new scene requirements.

[0125] For one possible implementation, please refer to [link / reference needed]. Figure 8 The projection module 10 is provided with a second driving member 19, which is mounted on the outer peripheral surface of the rotating member 12.

[0126] The second driving component 19 includes a second motor 191, a second rotating shaft 192, a second transmission structure 193, and a third transmission structure 194. The second motor 191 is fixedly connected to the outer peripheral surface of the rotating component 12. One end of the second rotating shaft 192 is rotatably connected to the second motor 191, and the other end is connected to the end face of the second transmission structure 193. The second transmission structure 193 and the third transmission structure 194 mesh. In this embodiment, the second transmission structure 193 is a worm gear, and the third transmission structure 194 is a helical gear. The worm gear meshes with the helical gear and drives the helical gear to rotate. For example, the axial direction of the worm gear can be perpendicular to the axial direction of the helical gear.

[0127] Specifically, the second motor 191 is connected to the second motor limiting body 1223. The second motor 191 is connected to the end face of the second motor limiting body 1223 facing the Z direction. The second rotating shaft 192 passes through the limiting hole 1223a and is exposed opposite to the limiting hole 1223a. The second transmission structure 193 is located on the side of the second motor limiting body 1223 facing the opposite direction of the Z direction. For example, the second transmission structure 193 can be a worm gear-like structure.

[0128] The third transmission structure 194 is sleeved on the first end 1412a of the shaft 1412, and the third transmission structure 194 meshes with the second transmission structure 193. The central axis of the third transmission structure 194 coincides with the central axis of the shaft 1412.

[0129] In this embodiment, the second motor 191 can drive the second rotating shaft 192 to rotate, thereby driving the second transmission structure 193 to rotate. The second transmission structure 193 can drive the shaft 1412 of the first reflector 14 to rotate through the third transmission structure 194, so as to change the position and angle of the reflecting surface of the first reflector 14.

[0130] For some possible implementations, please refer to [link / reference]. Figure 9 , Figure 9 yes Figure 3 The diagram shows the assembly of the second driving member 19 with the first reflector 14. The second driving member 19 also includes a shielding member 195 and a second bearing 196. The second bearing 196 is sleeved on the first end 1412a and is distributed in the Y direction with the third transmission structure 194. The outer ring of the second bearing 196 is connected to the wall of the first shaft hole 1221 of the second part 122.

[0131] The shield 195 includes a receiving portion 1951 and a connecting portion 1952. The receiving portion 1951 is used to accommodate the second transmission structure 193 and the third transmission structure 194. The connecting portion 1952 is used to connect the shield 195 to the second part 122.

[0132] The receiving portion 1951 is provided with a receiving groove 1951a and a clearance hole 1952b. The receiving groove 1951a is recessed from the surface of the receiving portion 1951. The clearance hole 1952b penetrates the side wall of the receiving groove 1951a and the outer surface of the receiving portion 1951. The clearance hole 1952b communicates the outside of the receiving portion 1951 with the receiving groove 1951a.

[0133] The connecting part 1952 is connected to the outer surface of the receiving part 1951.

[0134] The receiving portion 1951 covers the second transmission structure 193 and the third transmission structure 194. The receiving portion 1951 is located on the side of the second motor limit body 1223 facing the opposite direction of the Z direction. The second rotating shaft 192 protrudes from the clearance hole 1952b. The connecting portion 1952 is fixedly connected to the second portion 122.

[0135] In this embodiment, the shield 195 prevents tools, debris, or other foreign objects from accidentally falling into the meshing area of ​​the second transmission structure 193 and the third transmission structure 194, thus avoiding jamming or damage to the second transmission structure 193 and the third transmission structure 194. Simultaneously, the shield 195 prevents dust, moisture, chemicals, etc., from entering the meshing area of ​​the second transmission structure 193 and the third transmission structure 194, preventing lubricant contamination or gear corrosion.

[0136] It should be noted that the above-described method of using worm gear and gear transmission to drive the first reflector 14 to rotate is only an exemplary illustration of the rotation of the first reflector 14.

[0137] The second motor 191 can also be connected to the friction belt, and the motor drives the friction belt to rotate, thereby driving the first reflector 14 to rotate. Friction belt drive generally has high transmission efficiency, can effectively utilize friction, and has low energy loss in its transmission process. During torque transmission, the friction belt can closely adhere to the shaft 1412 of the first reflector 14, and efficiently transmit power to the first reflector 14 through friction.

[0138] Alternatively, the first reflector 14 can be connected to a chain, and the chain can be driven to rotate by a motor, thereby causing the first reflector 14 to rotate.

[0139] 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.

[0140] Alternatively, the first reflector 14 can be connected to a rack, and the rack can be moved by a motor to rotate the first reflector 14. When the second transmission structure 193 is a rack, the third transmission structure 194 can mesh with the rack. The rack transmission can maintain a constant transmission ratio, making power transmission stable and reliable, and providing precise control over output speed and torque.

[0141] In other possible implementations, the first reflector 14 can also be implemented by designing other specific transmission mechanisms, including but not limited to linkages, rocker arms, crankshafts, cams, pneumatic mechanisms, etc.

[0142] For one possible implementation, please refer to [link / reference]. Figure 3 The projection module 10 also includes a damping component 21. The damping component 21 is used to provide damping force for the rotation of the first reflector 14, so as to prevent the first reflector 14 from rotating unexpectedly and causing the projection area of ​​the projection module 10 to shift.

[0143] Specifically, please refer to the following: Figure 9 and Figure 10 , Figure 10 yes Figure 3 The diagram shows an exploded view of the damping assembly 21. The damping assembly 21 includes a mounting base 211 and a damping body 212. The damping body 212 is detachably connected to the mounting base 211.

[0144] Mounting base 211 includes a shaft connecting part 2111 and a rotating part connecting part 2112. The rotating part connecting part 2112 can be connected to the periphery of the shaft connecting part 2111.

[0145] The shaft connecting part 2111 is provided with a second shaft hole 2111a. The second shaft hole 2111a passes through the shaft connecting part 2111.

[0146] The rotating component connecting part 2112 is provided with two limiting protrusions 2112a and multiple connecting holes 2112b. The limiting protrusions 2112a are connected to the surface of the rotating component connecting part 2112. The two limiting protrusions 2112a are respectively located on opposite sides of the second shaft hole 2111a.

[0147] At least a portion of the shaft connecting part 2111 is installed within the mounting notch 1222. The connecting hole 2112b of the rotating member connecting part 2112 is opposite to the damping member limiting body 1224 on the second part 122. The damping member limiting body 1224 and the hole wall of the connecting hole 2112b can be fixedly connected by screws. The limiting protrusion 2112a is located on the side of the rotating member connecting part 2112 away from the second part 122 of the rotating member 12. The second end 1412b of the shaft 1412 of the first reflector 14 passes through the second shaft hole 2111a.

[0148] Please refer to the following: Figure 10 and Figure 11 , Figure 11 yes Figure 3 The diagram shows a cross-sectional view of the first reflector 14 assembled with the damping assembly 21. The damping body 212 may include a wave spring 2121, a first friction plate 2122, a second friction plate 2123, and a fixing member 2124. The wave spring 2121, the first friction plate 2122, and the second friction plate 2123 are stacked sequentially. The fixing member 2124 is used to fix the wave spring 2121, the first friction plate 2122, and the second friction plate 2123 to the second end 1412b.

[0149] A wave spring 2121 is sleeved on the second end 1412b of the shaft 1412 of the first reflector 14. There is a gap between the wave spring 2121 and the outer peripheral surface of the second end 1412b. The wave spring 2121 does not rotate with the rotation of the second end 1412b.

[0150] The first friction plate 2122 is sleeved on the second end 1412b of the shaft 1412 of the first reflector 14. The first friction plate 2122 is located on the side of the wave spring 2121 away from the mounting base 211. The periphery of the first friction plate 2122 abuts against the two limiting protrusions 2112a.

[0151] The second friction plate 2123 is sleeved on the second end 1412b of the shaft 1412 of a reflector. The second friction plate 2123 is in contact with the outer peripheral surface of the second end 1412b. The second friction plate 2123 rotates as the second end 1412b rotates.

[0152] The fastener 2124 can be a screw. The fastener 2124 can be threaded onto the second end 1412b. The head of the screw can abut against the surface of the second friction plate 2123 away from the first friction plate 2122, thereby compressing the spring 2121. The spring 2121 abuts between the first friction plate 2122 and the mounting base 211. The spring 2121 can increase the interaction force between the first friction plate 2122 and the second friction plate 2123, thereby increasing the frictional force between the first friction plate 2122 and the second friction plate 2123.

[0153] In this embodiment, when the first reflector 14 is subjected to an external force, the damping body 212 generates a reverse torque due to the friction between the first friction plate 2122 and the second friction plate 2123. When the magnitude of the external force is less than the magnitude of the damping force, the first reflector 14 does not rotate, thereby reducing the swaying of the first reflector 14 when no angle adjustment is required, which affects the swaying of the illumination position of the projection module 10. When the magnitude of the external force is greater than the damping force, the first reflector 14 can rotate, thereby stably adjusting the illumination area of ​​the projection module 10 and stably switching the user's usage scenario.

[0154] In other embodiments, the damping body 212 may also be a friction damping element or an electromagnetic damping element of other structures. This application does not limit the specific structure of the damping body 212.

[0155] In some possible implementations, the damping assembly 21 may further include a third bearing 213. The inner ring of the third bearing 213 is fitted onto the second end 1412b. The outer ring of the third bearing 213 is located within the second shaft hole 2111a of the shaft connection portion 2111 of the mounting base 211 and contacts the hole wall of the second shaft hole 2111a.

[0156] Please see Figure 12 , Figure 12 yes Figure 3 The diagram shows the structure of the first reflector 14 and the second reflector 15 assembled on the rotating member 12. The second reflector 15 is connected to the outer peripheral surface of the second part 122. The first reflector 14 is located on the side of the second reflector 15 facing the opposite direction to the X direction.

[0157] The second reflector 15 includes a second bracket 151, a second cover 152, and a second mirror 153. The second bracket 151 and the second cover 152 are connected to form a receiving space, and the second mirror 153 can be installed in the receiving space.

[0158] Specifically, the second bracket 151 is fixedly connected to the second reflector limiting body 1225.

[0159] The second mirror body 153 is connected to one side of the second support 151. The surface of the second mirror body 153 facing away from the second support 151 is the reflecting surface of the second reflector 15. The reflecting surface of the second reflector 15 is spaced apart from the reflecting surface of the first reflector 14.

[0160] The second cover 152 covers the periphery of the surface of the second mirror 153 facing away from the second bracket 151. The second cover 152 is attached to the periphery of the second bracket 151. The second cover 152 and the second bracket 151 can form a receiving space for the second mirror 153 to be installed.

[0161] In this embodiment, the second reflector 15 is fixed relative to the rotating member 12. The first reflector 14 and the second reflector 15 can utilize the space recessed between the outer peripheral surface of the second part 122 and the outer peripheral surface of the first part 121, thereby improving the space utilization of the projection module 10.

[0162] For one possible implementation, please refer to Figure 13 and Figure 14 , Figure 13 yes Figure 2 The diagram shows the projection module 10 in the first projection mode. Figure 14 yes Figure 2 The projection module 10 shown is in the second projection mode.

[0163] The projection module 10 includes a first projection mode and a second projection mode.

[0164] When the projection module 10 is in the first projection mode, the reflective surface of the first reflector 14 is parallel to the line containing the X direction. At this time, the light emitted by the light source 13 is not reflected by the reflective surface of the first reflector 14.

[0165] In this embodiment, when the reflective surface of the first reflector 14 is parallel to the line containing the X direction, the light emitted by the light source 13 can propagate directly to the outside of the projection module 10 without being emitted through the reflective surface of the first reflector 14. At this time, the projection module 10 can be in the mode of low beam or high beam of a vehicle headlight 100.

[0166] When the projection module 10 is in the second projection mode, the second motor 191 can drive the second rotating shaft 192 to rotate the second transmission structure 193. The second transmission structure 193 drives the first reflector 14 to rotate through the third transmission structure 194, so that the angle between the reflective surface of the first reflector 14 and the straight line containing the first direction is an acute angle, and the reflective surface of the first reflector 14 is opposite to the reflective surface of the second reflector 15.

[0167] When the angle between the reflective surface of the first reflector 14 and the straight line containing the first direction is acute, the light emitted by the light source 13 will be reflected by the surface of the first reflector 14. The light reflected by the first reflector 14 will then be reflected again by the second reflector 15, thereby changing the direction of propagation. At this time, the illuminated area can be in the near-field welcome mode of the vehicle headlights 100.

[0168] For one possible implementation, please refer to Figure 14 and Figure 15 , Figure 15 yes Figure 14 The diagram shows a cross-sectional view of the projection module 10. The projection module 10 is also provided with a first driving member 22. One end of the first driving member 22 is fixedly connected to the rotating member 12, and the other end contacts the mounting body 112 and is used to roll on the outer surface of the mounting body 112. The first driving member 22 is used to drive the rotating member 12 to rotate relative to the mounting body 112.

[0169] In this embodiment, the first driving member 22 can enable the rotating member 12 to rotate relative to the mounting body 112, thereby driving the first reflector 14 and the second reflector 15 to rotate relative to the light source 13, so as to change the illumination area of ​​the light source 13.

[0170] Specifically, the first driving component 22 includes a first motor 221, a first rotating shaft 222, and a first transmission structure 223. One end of the first rotating shaft 222 is connected to the first motor 221, and the other end is connected to the first transmission structure 223. The first motor 221 can drive the first rotating shaft 222 to rotate, thereby driving the first transmission structure 223 to rotate.

[0171] The first motor 221 is fixedly connected to the protrusion 1214 on the first part 121. At least part of the first motor 221 is located in the second connecting hole 1215 of the protrusion 1214. One end of the first rotating shaft 222 is connected to the first motor 221, and the other end passes through the first connecting hole 1211 of the first part 121 and is connected to the end face of the first transmission structure 223. The peripheral surface of the first transmission structure 223 contacts the groove wall of the sliding groove 1123 of the mounting body 112.

[0172] In this embodiment, the first motor 221 can make the rotating component 12 rotate automatically around the X-direction as the central axis. The high-precision control capability of the motor ensures that the first transmission structure 223 moves at a predetermined speed when it rotates, thereby making the rotation angle of the rotating component 12 relative to the mounting body 112 more accurate, so as to make the positioning of the illumination area of ​​the projection module 10 more accurate and improve the user experience.

[0173] In this embodiment, the rotation direction of the rotating member 12 is different from the rotation direction of the first reflector 14, so that the angle of the first reflector 14 can change in different directions, so that the propagation direction of the light of the projection module 10 can be flexibly changed in different directions, thereby expanding the field of view of the projection module 10.

[0174] Since the rotating component 12 can simultaneously drive the first reflector 14 and the second reflector 15 to rotate, the relative position of the first reflector 14 and the second reflector 15 changes little. The second reflector 15 can remain within the path of the light reflected by the first reflector 14, preventing the light reflected by the first reflector 14 from not reaching the second reflector 15 due to the movement of the first reflector 14, thus causing the second reflector 15 to lose its function of changing the light path.

[0175] During the use of the vehicle light 100, the controller 20 can determine the working state of the vehicle light 100, or the controller 20 can receive signals or instructions from the cockpit or other control domains, and drive the first reflector 14 and the rotating member 12 to move based on the instructions of the working state, so that the vehicle light 100 is in different working states.

[0176] For example, the vehicle light 100 includes a first working state, a second working state, and a third working state.

[0177] For the first operating state of the vehicle headlight 100, please refer to [link / reference]. Figure 16 , Figure 16 yes Figure 1 The diagram shows the vehicle 1000 in its first operating state. The projection module 10 can be in the first projection state described above, with the reflective surface of the first reflector 14 parallel to the line containing the X direction. At this time, the light emitted by the light source 13 is not reflected by the reflective surface of the first reflector 14.

[0178] At this time, the first reflector 14 and the second reflector 15 do not adjust the optical path of the light source 13. The headlight 100 can be used for common high beam or low beam applications.

[0179] For the second operating state of the vehicle headlight 100, please refer to [link / reference]. Figure 17 , Figure 17 yes Figure 1The diagram shows the vehicle 1000 in its second operating state. The angle of the rotating member 12 can be adjusted by the first driving member 22, and the angle of the first reflector 14 can be adjusted by the second driving member 19. At this time, after the headlight 100 is installed on the vehicle 1000, the extension direction of the rotation center axis of the projection module 10 (the central axis of the first light-transmitting hole 1110) can be the X direction. When the first driving member 22 drives the rotating member 12 to rotate around the rotation center axis, it can drive the first reflector 14 and the second reflector 15 to rotate around the rotation center axis, so that the projection area of ​​the light can change in the left-right direction of the vehicle 1000.

[0180] At this time, the projection area of ​​the headlight 100 can be changed either all at once or in real time. When the vehicle 1000 is in motion, the projection area can illuminate the left and right auxiliary lanes by changing the direction of the vehicle 1000. Alternatively, during the turning process of the vehicle 1000, the illuminated area can be changed in real time at different positions on the curve, thereby avoiding blind spots during the turning process and improving driving safety in dark conditions. Furthermore, during the passing process, the illuminated area can be flexibly adjusted left and right to avoid illuminating oncoming vehicles and causing them to have blurred vision or glare, which could seriously affect their driving judgment and operation.

[0181] Simultaneously, the direction of light propagation is adjusted by rotating the rotating component 12 and the first reflector 14. At this time, the projection area of ​​the headlight 100 can flexibly change between near and far distances around the vehicle 1000. When the vehicle is parked, the headlight 100 can provide a large-area moving light source 13, creating effects such as a light carpet or near-field welcome. When the vehicle is in motion, the projection area can adapt to various complex road surfaces, thus accurately illuminating the driving area.

[0182] When the headlight 100 is in its third operating state, please refer to [link / reference]. Figure 18 , Figure 18 yes Figure 1 The diagram shows the vehicle 1000 in its third operating state. The angle of the first reflector 14 can be adjusted by the second drive member 19, while the rotating member 12 remains stationary. At this time, the first reflector 14 can rotate around the central axis of the shaft 1412, so that the projection area of ​​the light can change in the near and far directions of the vehicle 1000.

[0183] At this time, the projection area of ​​the headlight 100 can be changed once or in real time. When the vehicle 1000 is in motion, the projection area changes depending on the distance of the vehicle 1000, which allows the driver to easily switch between low beam and high beam and flexibly adjust the position of the high and low beams to adapt to road surfaces with slopes.

[0184] In one possible design, this application also provides a control system, including a controller 20 and a projection module 10 as described above, wherein the controller 20 is capable of controlling the rotating member 12 to drive the first reflector 14 and the second reflector 15 to move.

[0185] The above are exemplary embodiments of this application. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.
