[0074] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0075] According to the first aspect of this application, referring to Figures 1 to 3 This application provides a lighting device 100, including: a device frame 110, an adjustment bracket 121, a first type of light module 131 and a second type of light module 132.

[0076] The adjustment bracket 121 is movably connected to the device frame 110, allowing the adjustment bracket 121 to be adjusted in attitude relative to the device frame 110. The adjustment bracket 121 includes a first mounting portion 121a and a second mounting portion 121b arranged along a predetermined direction D1. A first type of optical module 131 is mounted to the first mounting portion 121a, and a second type of optical module 132 is mounted to the second mounting portion 121b, thereby defining the relative positions of the first type of optical module 131 and the second type of optical module 132 in the predetermined direction. At least one of the first type of optical module 131 and the second type of optical module 132 is configured to be movably connected to the adjustment bracket 121, so that at least one of the first type of optical module 131 and the second type of optical module 132 has a degree of freedom of movement along the predetermined direction D1.

[0077] It is understood that either the first type of optical module 131 or the second type of optical module 132 is movably connected to the adjustment bracket 121, or either the first type of optical module 131 or the second type of optical module 132 is movably connected to the adjustment bracket 121 respectively. This degree of freedom can be at least one of deflection or translation, allowing the relative pose of the first type of optical module 131 and the second type of optical module 132 (e.g., the relative positions of the two types of optical modules or the angle between their optical axes) to be adjusted as needed.

[0078] Through the above technical solution, by setting an adjustment bracket 121 movably connected to the device frame 110, and simultaneously installing the first type of light module 131 and the second type of light module 132 on the adjustment bracket 121, the adjustment bracket 121 can simultaneously dim the two types of light modules; and at least one of the first type of light module 131 and the second type of light module 132 is movably connected to the adjustment bracket 121, which can realize the adjustment of the relative pose of the two types of light modules. Therefore, this application, while meeting the dimming requirements, can improve the compactness of the spatial layout of the lighting device 100 and reduce the overall space occupied by the lighting device 100.

[0079] In some specific implementations, the first type of light module 131 may include high and low beam headlights; the second type of light module 132 may include a Digital Light Processing (DLP) projection lamp, which projects part of the navigation image onto the ground to guide the vehicle and improve driving safety during vehicle operation. Of course, the lighting functions of the first type of light module 131 and the second type of light module 132 can be selected according to actual needs.

[0080] In some specific implementation methods, refer to Figure 2 , Figure 3 and Figure 5 The device frame 110 has a receiving space 113, in which the adjusting bracket 121, the first type of light module 131, and the second type of light module 132 are respectively disposed. The device frame 110 can be part of the vehicle body or an independent assembly. More specifically, the device frame 110 includes a housing 110a and a cover 110b, which are connected to form the receiving space 113 to protect the first type of light module 131 and the second type of light module 132, etc. A portion of the cover 110b is made of transparent material to allow light emitted by the light modules to pass through.

[0081] In some embodiments of this application, the angle between the predetermined direction D1 and the height direction of the lighting device 100 ranges from 0° to 10°.

[0082] It is understood that the height direction of the lighting device 100 can be the vertical direction (or the up-down direction) of the lighting device 100. It should be noted that the up-down, left-right, and front-back directions in this application are only to express relative positional relationships; they only indicate approximate locations, not absolute geometric relationships.

[0083] It is understood that the angle between the predetermined direction D1 and the height direction of the lighting device 100 can be the initial angle at which the adjustment bracket is installed on the device frame, or it can be the adjustable angle of the adjustment bracket relative to the device frame.

[0084] The angle between the predetermined direction D1 and the height direction of the lighting device 100 can be at least one of 0° to 1°, 1° to 2°, 2° to 3°, 3° to 4°, 4° to 5°, 5° to 6°, 6° to 7°, 7° to 8°, 8° to 9° or 9° to 10°.

[0085] This design allows the two types of optical modules to be arranged roughly vertically, and the vertical spacing between them allows for adjustment towards each other along a predetermined direction. Furthermore, in some optical module designs, the lenses are offset vertically, and the vertical spacing between the two types of optical modules provides offset space. Therefore, under this spatial arrangement, the vertical spacing between the two types of optical modules can be effectively utilized, reducing the overall volume of the two types of optical modules and lowering the molding cost of the device frame 110.

[0086] In some specific embodiments, based on the initial angle of the adjusting bracket 121, the angle at which the adjusting bracket 121 tilts backward relative to the device frame is 0° to 3°, and the angle at which the adjusting bracket 121 tilts forward relative to the device frame is 0° to 6.5°.

[0087] In some specific embodiments, the short sides of the lenses of the first type of optical module 131 and the second type of optical module 132 are arranged along a predetermined direction.

[0088] In some embodiments of this application, reference is made to Figure 7 and Figure 8 The lighting device 100 includes a first support joint 141 and a first floating joint 142.

[0089] The first support joint 141 is connected between the adjusting bracket 121 and the device frame 110; at least two first floating joints 142 are provided, and the first floating joints 142 are configured to receive external forces that cause the adjusting bracket 121 to rotate around the first support joint 141, so as to adjust the posture of the adjusting bracket 121 relative to the device frame 110; the first floating joints 142 are connected between the adjusting bracket 121 and the device frame 110.

[0090] It is understood that the first support joint 141 limits the degree of freedom of movement of the adjustment bracket 121 relative to the device frame 110 and limits the rotation center of the adjustment bracket 121, thereby ensuring the precise adjustment of the posture of the adjustment bracket 121. At least two first floating joints 142 are connected to different positions of the adjustment bracket 121. When the first floating joint 142 receives an external force that causes the adjustment bracket 121 to rotate around the first support joint 141, it can adapt to different postures of the adjustment bracket 121 to ensure the smooth operation of the adjustment bracket 121 and avoid jamming.

[0091] By adopting this scheme, the stability and reliability of the adjusting bracket 121 can be improved through the combination of the first supporting joint 141 and the first floating joint 142.

[0092] In some specific embodiments, the first support joint 141 includes either a ball joint mechanism or a universal joint, and the first floating joint 142 includes either a ball joint mechanism or a universal joint. The external force received by the first floating joint 142 can be provided by a threaded joint, a lead screw mechanism, or an electric actuator, etc.

[0093] In some embodiments of this application, reference is made to Figure 7 and Figure 8 The direction in which one of the first floating joints 142 and the first support joint 141 are spaced is defined as the first principal adjustment direction W1, and the direction in which the other first floating joint 142 and the first support joint 141 are spaced is defined as the second principal adjustment direction W2. The first principal adjustment direction W1 is perpendicular to the predetermined direction D1, and the second principal adjustment direction W2 is perpendicular to the first principal adjustment direction W1.

[0094] It can be understood that the first primary adjustment direction W1 is set parallel to the left-right direction. By applying a force to the first floating joints 142, which are spaced apart on the second primary adjustment direction W2, the adjustment bracket 121 can be driven to rotate around the first primary adjustment direction W1, thus achieving pitch adjustment of the adjustment bracket 121. By applying a force to the first floating joints 142, which are spaced apart on the first primary adjustment direction W1, the adjustment bracket 121 can be driven to rotate around the second primary adjustment direction W2, thus achieving angle adjustment of the adjustment bracket 121 in the left-right direction.

[0095] The number of first floating joints 142 can be selected according to actual design requirements (such as the mass and size of the adjusting bracket 121) to ensure the stability of the adjusting bracket 121.

[0096] In some specific embodiments, based on the initial angle of the adjusting bracket 121, the angle by which the adjusting bracket 121 deflects to the left or right relative to the device frame is 0° to 6°. More specifically, the angle by which the adjusting bracket 121 deflects to the left or right relative to the device frame is 0° to 3°.

[0097] In some embodiments of this application, reference is made to Figure 7 and Figure 8 The first supporting joint 141 includes a frame-side support 141a and a main-adjustment-side adapter 141b. The frame-side support 141a is fixedly connected to the device frame 110, and the main-adjustment-side adapter 141b is connected to the adjusting bracket 121. The main-adjustment-side adapter 141b and the frame-side support 141a constitute a ball joint mechanism, allowing the adjusting bracket 121 to movably engage with the device frame 110 using the ball joint mechanism formed by the main-adjustment-side adapter 141b and the frame-side support 141a as a fulcrum. Correspondingly, the adjusting bracket 121 is provided with a main-adjustment-side mounting structure 121d that mates with the main-adjustment-side adapter 141b.

[0098] In some embodiments of this application, reference is made to Figure 3 , Figure 8 and Figure 9 The first floating joint 142 includes a first slider 142a and a first floating adapter 142b. The first slider 142a is slidably connected to the device frame 110, allowing it to move relative to the device frame 110 in the front-back direction, thereby pushing the adjusting bracket 121 to rotate around the first support joint 141. The first floating adapter 142b is connected to the adjusting bracket 121 and forms a ball joint mechanism with the first slider 142a, thus adapting to different postures of the adjusting bracket 121. Correspondingly, the adjusting bracket 121 is provided with a first floating mounting structure 121e that cooperates with the first floating adapter 142b.

[0099] In some specific implementation methods, refer to Figure 3 , Figure 8 and Figure 9 The lighting device 100 further includes a first drive rod 181 and a first operating member 182. The first drive rod 181 is rotatably connected to the device frame 110 and is threadedly connected to the first slider 142a, so that the first slider 142a can be moved when the first drive rod 181 rotates. The first operating member 182 is rotatably connected to the device frame 110 and is used for user operation to drive the first drive rod 181 to rotate.

[0100] It is understood that the first operating element 182 can be directly coupled to the first drive rod 181, for example, the first operating element 182 and the first drive rod 181 can be driven by gears (e.g., bevel gears). Alternatively, the lighting device 100 may further include at least one transmission rod 183. The transmission rod 183 transmits power between the first operating element 182 and the first drive rod 181. The transmission rod 183 is rotatably connected to the housing 110a. The transmission rod 183 and the first operating element 182, the two transmission rods 183, and the transmission rod 183 and the first drive element are respectively driven by gears (e.g., bevel gears), thereby adapting to the spatial distribution of the first operating element 182 and the first drive rod 181.

[0101] In some embodiments of this application, reference is made to Figure 3 , Figure 8 and Figure 9The first floating joint 142 includes a second slider 142c, a second floating adapter 142d, and a motor 142e. The second slider 142c is slidably connected to the device frame 110, allowing it to move relative to the device frame 110 in the front-back direction, thereby pushing the adjusting bracket 121 to rotate around the first support joint 141. The second floating adapter 142d is anti-rotationally connected to the adjusting bracket 121. The motor 142e is fixedly connected to the second slider 142c, and the drive shaft of the motor 142e and the second floating adapter 142d form a ball joint mechanism, thereby adapting to different postures of the adjusting bracket 121. Correspondingly, the adjusting bracket 121 is provided with a second floating mounting structure 121f that cooperates with the second floating adapter 142d.

[0102] In some specific implementation methods, refer to Figure 3 , Figure 8 and Figure 9 The lighting device 100 further includes a second drive rod 184 and a second operating member 185. The second drive rod 184 is rotatably connected to the device frame 110 and is threadedly connected to the second slider 142c, so that the second slider 142c can be moved when the second drive rod 184 rotates. The second operating member 185 is rotatably connected to the device frame 110 and is used for user operation to drive the second drive rod 184 to rotate.

[0103] It should be noted that the setting of transmission rod 183 can be selected to be retained or discarded according to the spatial distribution of the second drive rod 184 and the second operating member 185.

[0104] In one example of this application, reference is made to Figure 7 and Figure 8 The first floating mounting structure 121e and the main adjustment side mounting structure 121d are spaced apart along the first main adjustment direction W1, and the second floating mounting structure 121f and the main adjustment side mounting structure 121d are spaced apart along the second main adjustment direction W2.

[0105] In some embodiments of this application, reference is made to Figures 3 to 6 , Figures 9 to 12 The lighting device 100 also includes a support member 150. At least two support members 150 are provided and are respectively disposed on both sides of the adjustment bracket 121 along the first main adjustment direction W1.

[0106] The device frame 110 has a limiting groove 111. The limiting groove 111 is formed on the inner wall of the device frame 110; wherein the extending direction of the limiting groove 111 intersects with the predetermined direction D1, and the support member 150 and the limiting groove 111 are in a movable fit.

[0107] By adopting this scheme, the support member 150 and the limiting slide 111 cooperate to provide support for the adjusting bracket 121 during the posture adjustment process, thereby improving the stability of the adjusting bracket 121.

[0108] It is understandable that the support component 150 and the adjustment bracket 121 can be set separately or integrally formed.

[0109] In some specific implementation methods, refer to Figure 4 , Figures 8 to 10 The adjusting bracket 121 is symmetrically provided with two shafts 121c along the first main adjusting direction W1. At least part of the bearing member 150 is fitted onto the shaft 121c and forms an anti-rotation connection with the shaft 121c, that is, the bearing member 150 and the adjusting bracket 121 move synchronously.

[0110] In some embodiments of this application, reference is made to Figure 3 and Figure 4 The carrier 150 includes: an adapter 151 and a limiting part 152.

[0111] The adapter 151 has an arcuate surface 151a arranged around the first main adjustment direction W1, and the arcuate surface 151a contacts the groove wall of the limiting slide 111; the limiting part 152 protrudes from the arcuate surface 151a, and the limiting part 152 and the adapter 151 are arranged at different positions on the carrier 150 in the circumferential direction of the carrier 150.

[0112] It can be understood that the arc-shaped surface 151a is distributed on the circumferential surface of the support member 150, allowing the support to rotate relative to the device frame 110. At the same time, by setting the limiting part 152, when the support member 150 rotates to the point where the limiting part 152 abuts against the groove wall of the limiting slide groove 111, the support member 150 is restricted from continuing to rotate relative to the device frame 110, thereby limiting the adjustment range of the pitch angle of the adjusting bracket 121.

[0113] Specifically, the groove wall of the limiting slide 111 is set horizontally to ensure the stability of the adjusting bracket.

[0114] In some embodiments of this application, reference is made to Figure 3 , Figure 13 and Figure 14 The lighting device 100 includes: a mounting bracket 122, a second support joint 161, and a second floating joint 162.

[0115] Mounting bracket 122 has a mounting structure for connecting a second type of optical module 132; a second support joint 161 is connected between mounting bracket 122 and adjusting bracket 121; at least two second floating joints 162 are provided, each configured to receive an external force that causes mounting bracket 122 to rotate around the second support joint 161, so as to adjust the posture of mounting bracket 122 relative to adjusting bracket 121; the second floating joint 162 is connected between mounting bracket 122 and adjusting bracket 121.

[0116] It is understood that the second support joint 161 limits the relative adjustment freedom of the mounting bracket 122 and the rotation center of the adjusting bracket 121, thereby ensuring the precise adjustment of the posture of the adjusting bracket 121. At least two second floating joints 162 are connected to different positions of the mounting bracket 122. When the second floating joint 162 receives an external force that causes the mounting bracket 122 to rotate around the second support joint 161, it can adapt to different postures of the mounting bracket 122 to ensure the smooth operation of the adjusting bracket 121 and avoid jamming.

[0117] By adopting this approach, the stability and reliability of the mounting bracket 122 can be improved through the combination of the second support joint 161 and the second floating joint 162.

[0118] In some specific embodiments, the second support joint 161 includes either a ball joint mechanism or a universal joint, and the second floating joint 162 includes either a ball joint mechanism or a universal joint. The external force received by the second floating joint 162 can be provided by a threaded joint, a lead screw mechanism, or an electric actuator, etc.

[0119] In some embodiments of this application, reference is made to Figure 13 and Figure 14 The direction in which one of the second floating joints 162 and the second support joint 161 are spaced apart is defined as the first secondary adjustment direction U1, and the direction in which the other second floating joint 162 and the second support joint 161 are spaced apart is defined as the second secondary adjustment direction U2; the first secondary adjustment direction U1 is perpendicular to the predetermined direction D1, and the second secondary adjustment direction U2 is perpendicular to the first secondary adjustment direction U1.

[0120] It can be understood that the first secondary adjustment direction U1 is set parallel to the left-right direction. By applying a force to the second floating joints 162, which are spaced apart on the second secondary adjustment direction U2, the mounting bracket 122 can be driven to rotate around the first secondary adjustment direction U1, thus achieving pitch adjustment of the mounting bracket 122. By applying a force to the second floating joints 162, which are spaced apart on the first secondary adjustment direction U1, the mounting bracket 122 can be driven to rotate around the second secondary adjustment direction U2, thus achieving angle adjustment of the mounting bracket 122 in the left-right direction.

[0121] The number of second floating joints 162 can be selected according to actual design requirements (such as the mass and size of the mounting bracket 122) to ensure the stability of the mounting bracket 122.

[0122] In some embodiments of this application, reference is made to Figure 13 and Figure 14 The second support joint 161 includes a main adjustment side support 161a and a secondary adjustment side adapter 161b. The main adjustment side support 161a is fixedly connected to the adjustment bracket 121, and the secondary adjustment side adapter 161b is connected to the mounting bracket 122. The main adjustment side support 161a and the secondary adjustment side adapter 161b constitute a ball joint mechanism, allowing the mounting bracket 122 to movably engage with the adjustment bracket 121 using the ball joint mechanism formed by the main adjustment side support 161a and the secondary adjustment side adapter 161b as a fulcrum. Correspondingly, the mounting bracket 122 is provided with a secondary adjustment side mounting structure 122a that mates with the secondary adjustment side adapter 161b.

[0123] In some embodiments of this application, reference is made to Figure 3 and Figure 8 The second floating joint 162 includes an adjusting screw 162a and a third floating adapter 162b. The adjusting screw 162a is threadedly connected to the adjusting bracket 121, allowing it to move relative to the adjusting bracket 121 in the front-back direction during rotation, thereby pushing the mounting bracket 122 to rotate around the second supporting joint 161. The third floating adapter 162b is connected to the mounting bracket 122 and forms a ball joint mechanism with the adjusting screw 162a, thus adapting to different postures of the mounting bracket 122. Correspondingly, the mounting bracket 122 is provided with a third floating mounting structure 122b that cooperates with the first floating adapter 142b.

[0124] In one example of this application, reference is made to Figure 13 and Figure 14 One of the third floating installation structures 122b and the secondary adjustment side installation structure 122a are spaced apart along the first secondary adjustment direction U1, and the other third floating installation structure 122b and the secondary adjustment side installation structure 122a are spaced apart along the second secondary adjustment direction U2.

[0125] In some embodiments of this application, reference is made to Figure 9 , Figure 11 and Figure 15 The device frame 110 has a vent 112. The vent 112 is formed on the side wall of the device frame 110 and communicates with the outside. More specifically, the vent 112 is formed on the rear side wall of the housing 110a.

[0126] The lighting device 100 also includes a drainage sleeve 171 and a fan 172. The drainage sleeve 171 has a drainage channel 171a that connects the vent 112 to the second type of light module 132; the fan 172 is configured to cause air to flow in the drainage channel 171a, thereby carrying away the heat generated by the second type of light module 132; the fan 172 is mounted on the second type of light module 132 or the device frame 110.

[0127] By adopting this design and using the air-draining sleeve 171, the fan 172 is directed to operate only on the second type of optical module 132, reducing airflow loss and improving heat dissipation efficiency. Simultaneously, the air-draining sleeve 171, due to its good deformation capability, can adapt well to different positions of the second type of optical module 132 during dimming.

[0128] In some specific implementation methods, refer to Figure 9 , Figure 11 and Figure 15 The drainage sleeve 171 includes a first connecting portion 171b and a second connecting portion 171c. The first connecting portion 171b and the second connecting portion 171c are located at both ends of the drainage sleeve 171, respectively.

[0129] The lighting device 100 also includes a crimping member 173. The crimping member 173 is fixedly connected to the device frame 110, and at least a portion of the first connecting portion 171b is clamped between the crimping member 173 and the device frame 110, thereby achieving a stable connection between the first connecting portion 171b and the device frame 110.

[0130] The fan 172 is mounted on the second type of optical module 132, and at least a portion of the second connecting part 171c is clamped between the fan 172 and the second type of optical module 132, thereby achieving a stable connection between the second connecting part 171c and the second type of optical module 132. More specifically, the second connecting part 171c is connected to the heat sink of the second type of optical module 132.
