Description

Technical Field

[0001] This application relates to headlight dimming technology for vehicles, and more particularly to a headlight assembly and a vehicle. Background Technology

[0002] With the rapid development of automotive lighting technology, Adaptive Front Lighting System (AFS, also known as AFS headlights) has been widely adopted. In order to enhance the appearance of automobiles and the convenience of nighttime use, exterior projection lights are also being used more and more widely. These projection lights can not only add a sense of technology and ceremony to vehicles at night by projecting specific patterns, logos or light carpets, but also serve the functions of finding the car and illuminating the road.

[0003] In related technologies, the Adaptive Front Lighting System (AFS, also known as AFS headlights) can automatically adjust the illumination center of the low beam headlights according to the vehicle speed and steering wheel angle, ensuring that the light is always pointed to the inside of the curve, thereby expanding the effective lighting range when turning. Meanwhile, the projection lamp is usually installed on the vehicle's bumper, side panel, or rearview mirror, etc., to project images in a fixed position.

[0004] However, since the vehicle's projection lights are installed in a fixed position, the image quality is affected by the positional deviation. When the user is driving the vehicle, the AFS headlights can expand the illumination range when turning, but the image of the fixed-position projection lights contrasts with the illumination range of the AFS headlights, resulting in an insufficient user experience. Utility Model Content

[0005] In view of this, this application provides a vehicle lighting assembly and a vehicle that enables the projection light to be adjusted accordingly, thereby improving the user experience.

[0006] To achieve the above objectives, this application provides a vehicle lighting assembly and vehicle, which adopts the following technical solution:

[0007] In a first aspect, this application provides a vehicle lighting assembly, including a dimming bracket, a low beam headlight, and a projection lamp;

[0008] The dimming bracket can be rotatably mounted on the vehicle body;

[0009] The low beam lamp is mounted on the dimming bracket, and the low beam lamp can emit light in a direction away from the dimming bracket;

[0010] The projection lamp is mounted on the dimming bracket, and the light emission direction of the projection lamp is parallel to the light emission direction of the low beam lamp.

[0011] In one possible implementation, the vehicle lighting assembly provided in this application further includes two adjustment mechanisms;

[0012] The dimming bracket is rotatably connected to the vehicle body via the adjustment mechanism; the two adjustment mechanisms are arranged at a distance in the horizontal direction, with one adjustment mechanism located at the top of the dimming bracket and the other adjustment mechanism located at the bottom of the dimming bracket.

[0013] In one possible implementation, the vehicle lighting assembly provided in this application includes an adjustment mechanism comprising:

[0016] The base is connected to the dimming bracket, and the base has a limiting groove, in which the ball head of the ball head rod is movably locked.

[0017] One of the limiting grooves extends horizontally, and the other limiting groove extends vertically.

[0018] In one possible implementation, the vehicle lighting assembly provided in this application includes a projection lamp with a mounting bracket, and the projection lamp can be connected to the dimming bracket via the mounting bracket.

[0019] The mounting bracket is provided with a light-avoiding opening, which faces the low beam lamp.

[0020] In one possible implementation, the vehicle light assembly provided in this application has a mounting bracket with at least one snap-fit ​​structure, through which the mounting bracket can be connected to the dimming bracket.

[0021] In one possible implementation, the vehicle light assembly provided in this application has a plurality of snap-fit ​​structures, including a first snap-fit ​​structure, a second snap-fit ​​structure, and a third snap-fit ​​structure.

[0022] The first and second locking structures are arranged horizontally and are located on both sides of the light-avoiding port; the third locking structure is located below the light-avoiding port.

[0025] In one possible implementation, the vehicle light assembly provided in this application has a mounting bracket with a snap-fit ​​groove.

[0026] The projection lamp is provided with multiple snap-fit ​​parts, which can be close to or far from each other, and the snap-fit ​​parts are inserted into the snap-fit ​​grooves; the ends of the snap-fit ​​parts are provided with snap-fit ​​connectors, which abut against the surface of the mounting bracket away from the projection lamp.

[0027] Secondly, this application provides a vehicle, including a body and at least one of the above-described vehicle light components; the vehicle light is disposed on the body.

The parallel light emission direction of the projection lamp and the low beam headlight ensures the positional stability of the projected pattern (such as a logo or light carpet) on the road surface, preventing the projection from deviating from the target area due to vehicle turning. This dynamic adjustment capability enhances the practicality of nighttime vehicle location and road illumination functions, while also improving the sense of technology and ceremony. When driving on a curve, the projection lamp points synchronously to the inside of the curve along with the low beam headlight, expanding the effective illumination range of the low beam headlight while ensuring that the projected pattern is always within the driver's field of vision, balancing functionality and aesthetics, and improving the user experience.

Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0045] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0046] In the description of the embodiments of this application, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0047] In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise specified precisely.

[0048] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0049] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0050] In recent years, to improve driving safety and comfort, Adaptive Front Lighting Systems (AFS, also known as AFS headlights) have been widely adopted. AFS headlights work by automatically adjusting the center of the low beam based on vehicle speed and steering wheel angle, ensuring the light always points towards the inside of curves, thus expanding the effective illumination range when turning. AFS headlight systems are typically also equipped with an Automatic Light Axis Adjustment System (ALS), which automatically adjusts the light axis as the vehicle's posture changes, maintaining horizontal illumination and avoiding interference with oncoming vehicles.

[0051] To enhance the appearance of cars and improve their convenience for nighttime use, exterior projection lights are becoming increasingly widely used. These projection lights not only add a sense of technology and ceremony to vehicles at night by projecting specific patterns, logos, or light carpets, but also serve to locate the car and illuminate the road.

[0052] In related technologies, AFS headlights are mostly used independently, and external projection lights are mostly installed on bumpers, side panels, or rearview mirrors to project images in fixed positions.

[0053] The vehicle's projection lights are installed in a fixed position, and the image quality is affected by the positional deviation. When the user is driving the vehicle, the AFS headlights can expand the illumination range when turning, but the image of the fixed-position projection lights contrasts with the illumination range of the AFS headlights. The projection cannot move in the direction of turning, resulting in insufficient user experience and no increase in driving safety.

[0054] To address the aforementioned technical issues, this application provides a vehicle lighting assembly and a vehicle. In this solution, the vehicle lighting assembly includes a dimming bracket, a low beam headlight, and a projection lamp. The dimming bracket is rotatably mounted on the vehicle body. The low beam headlight is mounted on the dimming bracket and emits light in a direction away from the dimming bracket. The projection lamp is mounted on the dimming bracket, and its light emission direction is parallel to that of the low beam headlight. When the vehicle turns, the dimming bracket drives the projection lamp and low beam headlight to synchronously adjust their illumination directions, ensuring that the projection lamp's image is always consistent with the vehicle's direction of travel, thus avoiding projection offset or distortion caused by a fixed position.

[0055] The projection lamp's beam direction is parallel to that of the low beam headlights, ensuring the stability of the projected pattern (such as a logo or light carpet) on the road surface and preventing the projection from deviating from the target area due to vehicle turning. This dynamic adjustment capability enhances the practicality of nighttime vehicle location and road illumination functions, while also increasing the sense of technology and ceremony. When driving on curves, the projection lamp points synchronously to the inside of the curve along with the low beam headlights, expanding the effective illumination range of the low beam headlights while ensuring that the projected pattern remains within the driver's field of vision, balancing functionality and aesthetics, and improving the user experience.

[0056] In this embodiment, the projection lamp is installed in the AFS headlight, and the mounting bracket of the projection lamp is interlocked and adjusted with the dimming bracket of the low beam headlight. The AFS headlight automatically adjusts the illumination center of the low beam headlight according to the vehicle speed and steering wheel angle to ensure that the light always points to the inside of the curve. When the low beam headlight is adjusted left and right, the projection lamp rotates left and right synchronously so that the projected image also always points to the inside of the curve. For example, when the vehicle turns in the underground parking lot, the turning image projected by the projection lamp also rotates to always point to the inside of the curve, which increases the interactive warning between the vehicle and the driver and enhances driving safety. The AFS headlight can automatically adjust the light axis when the vehicle body posture changes to maintain horizontal illumination. The imaging quality of the projection lamp is affected by positional deviation. For example, when the front of the car is tilted up and the headlight automatically adjusts downward, the projection lamp moves down synchronously to keep the imaging reference axis consistent, ensuring the image quality and avoiding defects such as blurring and misalignment.

[0057] This application ensures image quality, enhances user experience and driving safety, while also having lower component costs, lower power consumption, and higher operability and feasibility, reducing development workload and costs.

[0058] It should be noted that, Figures 1 to 10 This diagram illustrates a simplified schematic of the headlight assembly and other components within the vehicle. The specific structures of the headlight assembly and other components in the vehicle are not limited to these examples. Figures 1 to 10 of examples.

[0059] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0060] Reference Figure 1 , Figure 2 and Figure 7 As shown in the embodiment of this application, a vehicle lighting assembly 10 includes a dimming bracket 100, a low beam lamp 200, and a projection lamp 300.

[0061] For those skilled in the art within the field of vehicle technology, the low beam headlight 200 falls within the relevant technical scope of that field. The dimming bracket 100 is rotatably mounted on the vehicle body; as mentioned in the background section, the AFS headlight can automatically adjust the illumination center of the low beam headlight 200 according to vehicle speed and steering wheel angle. The fact that the dimming bracket 100 is rotatably mounted on the vehicle body can be understood as the dimming bracket 100 and the low beam headlight 200 being components of the AFS headlight.

[0062] The low beam lamp 200 is mounted on the dimming bracket 100. In practice, the low beam lamp 200 can be fixed to the dimming bracket 100, for example, by welding. The low beam lamp 200 can also be detachably connected to the dimming bracket 100, which can facilitate the maintenance and replacement of the low beam lamp 200 and improve maintenance efficiency.

[0063] This application embodiment does not impose specific limitations on the connection relationship between the low beam headlight 200 and the dimming bracket 100. The low beam headlight 200 can emit light in a direction away from the dimming bracket 100; it is understood that, in a conventional setting, the dimming bracket 100 provides a mounting base for the low beam headlight 200, and the low beam headlight 200 can emit light towards the outside of the vehicle 20. Furthermore, there is no limitation on the number of low beam headlights 200; the number of low beam headlights 200 can be selected according to actual design requirements.

[0064] The projection lamp 300 is mounted on the dimming bracket 100, and the light output direction of the projection lamp 300 is parallel to the light output direction of the low beam lamp 200.

[0065] In the above embodiment, by mounting the projection lamp 300 and the low beam lamp 200 together on a rotatable dimming bracket 100, the projection lamp 300 can turn synchronously with the AFS headlights. When the vehicle 20 turns, the dimming bracket 100 drives the projection lamp 300 and the low beam lamp 200 to adjust their illumination direction synchronously, ensuring that the image of the projection lamp 300 is always consistent with the driving direction of the vehicle 20, avoiding projection offset or distortion caused by a fixed position. The projection lamp 300 and the low beam lamp 200 emit light in parallel directions, ensuring the positional stability of the projected pattern (such as a logo or light carpet) on the road surface, preventing the projection from deviating from the target area due to the turning of the vehicle 20. This dynamic adjustment capability enhances the practicality of nighttime vehicle location and road illumination functions, while also improving the sense of technology and ceremony. When driving on a curve, the projection lamp 300 and the low beam lamp 200 point synchronously to the inside of the curve, which not only expands the effective illumination range of the low beam lamp 200, but also ensures that the projected pattern is always within the driver's field of vision, balancing functionality and aesthetics, and improving the user experience.

[0066] By integrating the projection lamp 300 and the low beam lamp 200 into the same dimming bracket 100, coordinated control of the optical system is achieved. The synchronous steering characteristic of both simplifies system complexity, reduces the risk of calibration errors caused by independent adjustments, and also reduces the need for modifications to the appearance of the vehicle 20.

[0067] In one possible implementation, refer to Figures 3 to 6 As shown, the vehicle headlight assembly 10 also includes two adjustment mechanisms 600; the dimming bracket 100 is rotatably connected to the vehicle body via the adjustment mechanisms 600; the two adjustment mechanisms 600 are arranged horizontally at intervals, with one adjustment mechanism 600 located at the top of the dimming bracket 100 and the other adjustment mechanism 600 located at the bottom of the dimming bracket 100. In specific implementation, the adjustment mechanism 600 may be mounted on the vehicle body, and this application embodiment does not limit the connection structure between the adjustment mechanism 600 and the vehicle body.

[0068] In the horizontal direction, two adjustment mechanisms 600 are arranged at intervals. This can be understood as the dimming bracket 100 having two rotation points in the horizontal direction. The dimming bracket 100 can rotate with either rotation point as the origin to adjust the azimuth angle of the light emitted by the headlight assembly 10. In the vertical direction, one adjustment mechanism 600 is located at the top of the dimming bracket 100, and the other adjustment mechanism 600 is located at the bottom of the dimming bracket 100. This allows the dimming bracket 100 to rotate in the vertical direction, thereby adjusting the pitch angle of the light emitted by the headlight and expanding the dimming range of the headlight assembly 10.

[0069] In one possible implementation, the adjusting mechanism 600 includes:

[0070] The drive unit 610 is used to be mounted on the vehicle body and has an output shaft.

[0071] Ball joint 620, ball joint 620 is a telescopic rod, and the telescopic rod is fixedly connected to the output shaft.

[0072] The base 630 is connected to the dimming bracket 100. The base 630 has a limiting groove 631, and the ball head of the ball head rod 620 is movably locked in the limiting groove 631.

[0073] One of the limiting grooves 631 extends horizontally, and the other limiting groove 631 extends vertically.

[0074] It should be noted here that, for reference... Figure 4As shown, the ball joint 620 is a telescopic rod. This can be understood as the ball joint 620 itself being a telescopic rod, or as the ball joint 620 being able to extend or retract relative to the drive component 610. In short, it is sufficient to change the distance between the ball head of the ball joint 620 and the drive component 610. One end of the ball joint 620 is connected to the output end of the drive component 610, and the ball head is located on the side of the ball joint 620 facing away from the drive component 610.

[0075] The base 630 and the dimming bracket 100 can be fixed together by bolts or welded together. A limit groove 631 is provided on the side of the base 630 facing the drive component 610.

[0076] The driving component 610 can be a motor or other type of driving source. The embodiments of this application do not limit the implementation form of the driving component 610.

[0077] Reference Figure 5 As shown, in the horizontal direction, by extending or shortening one ball joint 620 and the other ball joint 620, the azimuth angle of the dimming bracket 100° can be changed. Figure 5 The positional states indicated by the dashed lines and thin dotted lines are only for illustration purposes and show that the dimming bracket 100 has multiple angles and positions. When the azimuth angle of the dimming bracket 100 is changed, one of the ball joint rods 620 extends, and the ball joint rotates and moves relative to the limiting groove 631 that it cooperates with. For example, when the limiting groove 631 is set vertically, the ball joint can slide up and down in the limiting groove 631, and when the limiting groove 631 is set horizontally, the ball joint can move horizontally in the limiting groove 631.

[0078] Similarly, refer to Figure 6 As shown, in the vertical direction, the pitch angle can be changed through the cooperation of the two ball joint rods 620 with their respective limiting grooves 631. Since the projector lamp 300 is mounted on the dimming bracket 100, changes in the azimuth and pitch angles of the dimming bracket 100 synchronously change the azimuth and pitch angles of the projector lamp 300. This achieves the effect of synchronous rotation or synchronous adjustment of the projector lamp 300 and the low beam lamp 200.

[0079] In one possible implementation, refer to Figure 7 Diagram and Figure 9 As shown, the projection lamp 300 is provided with a mounting bracket 400, and the projection lamp 300 can be connected to the dimming bracket 100 through the mounting bracket 400.

[0080] In the above embodiments, the mounting bracket 400 is designed as an independent component, separating the projection lamp 300 from the dimming bracket 100. This simplifies the installation process of the projection lamp 300, for example, through the standardized connection between the mounting bracket 400 and the dimming bracket 100, and also facilitates later maintenance or replacement of the projection lamp 300 module, reducing the overall vehicle assembly complexity. The mounting bracket 400 provides an independent support structure for the projection lamp 300, avoiding stress concentration or vibration interference that may occur if it is directly fixed to the dimming bracket 100.

[0081] In one possible implementation, the mounting bracket 400 is provided with a light outlet 401 that avoids the light outlet 401 facing the low beam lamp 200.

[0082] In the above embodiments, if the mounting bracket 400 directly covers the front of the low beam lamp 200, it may block some light, resulting in a decrease in lighting intensity or the creation of shadows. By avoiding the light outlet 401, a path is left for the light from the low beam lamp 200, ensuring that its light output direction is not physically interfered with by the mounting bracket 400, thus maintaining the basic lighting function of the AFS headlights. Avoiding the light outlet 401 ensures that the mounting bracket 400 only serves as a support structure and does not participate in the obstruction of the optical path, ensuring that the pattern (such as a logo or light carpet) of the projection lamp 300 is adjusted synchronously with the illumination range of the low beam lamp 200, avoiding projection distortion or offset caused by the mounting bracket 400 obstructing the path.

[0083] Furthermore, by creating a recess for the light outlet 401 on the mounting bracket 400, instead of thickening or enlarging the bracket as a whole, functional requirements are met while achieving a lightweight design, reducing component costs and installation complexity. The recess for the light outlet 401 also indirectly provides a heat dissipation channel for the low beam lamp 200, accelerating heat dissipation through airflow and extending the lamp's lifespan.

[0084] In one possible implementation, the mounting bracket 400 is provided with at least one snap-fit ​​structure 500, through which the mounting bracket 400 can be connected to the dimming bracket 100.

[0085] In the above embodiment, by setting a snap-fit ​​structure 500, the snap-fit ​​structure 500 ensures a firm connection between the mounting bracket 400 and the dimming bracket 100 through mechanical locking, preventing loosening or displacement caused by vehicle vibration or steering torque, and ensuring the imaging stability of the projection lamp 300 when it is adjusted accordingly. The snap-fit ​​structure 500 simplifies the installation process, enabling quick assembly or disassembly without complicated tools, reducing production costs and maintenance difficulty, while also supporting modular replacement.

[0086] In one possible implementation, refer to Figure 7 , Figure 8 and Figure 9As shown, there are multiple snap-fit ​​structures 500, including a first snap-fit ​​structure 500a, a second snap-fit ​​structure 500b, and a third snap-fit ​​structure 500c.

[0087] like Figure 8 and Figure 9 It should be noted that the X, Y, and Z arrows are mutually perpendicular in three-dimensional space. In the Y direction, the first latching structure 500a and the second latching structure 500b are arranged horizontally, positioned on both sides of the light outlet 401 to avoid obstruction. In the Z direction, the third latching structure 500c is located below the light outlet 401.

[0088] In the above embodiment, the first snap-fit ​​structure 500a and the second snap-fit ​​structure 500b are arranged horizontally on both sides of the light-exit port 401 to restrict the lateral displacement of the mounting bracket 400 from the left and right sides, preventing the projection lamp 300 from swaying horizontally due to vehicle 20 bumps or steering torque. The third snap-fit ​​structure 500c is located below the light-exit port 401, providing vertical limiting and support to prevent the mounting bracket 400 from sagging or warping due to gravity or vibration, ensuring the relative position of the projection lamp 300 and the dimming bracket 100 is stable.

[0089] The combination of the first locking structure 500a, the second locking structure 500b, and the third locking structure 500c restricts the degrees of freedom of the mounting bracket 400 from multiple dimensions, forming a stable mechanical lock and ensuring the structural rigidity of the projection lamp 300 when it rotates with the dimming bracket 100. At the same time, it can distribute the connection force to different positions, avoid excessive stress on a single connection point, reduce the risk of local wear or deformation, and improve the durability of the components.

[0090] In one possible implementation, the snap-fit ​​structure 500 includes a plurality of plugs 510.

[0091] The dimming bracket 100 is provided with multiple insertion slots 101, and the multiple insertion slots 101 are correspondingly provided with multiple insertion pieces 510, with the insertion pieces 510 inserted into the corresponding insertion slots 101.

[0092] In the above embodiments, the connector 510 and the connector slot 101 of the dimming bracket 100 are tightly connected by physical interference fit to avoid loosening due to vehicle 20 vibration or steering torque, and to ensure the structural stability of the projection lamp 300 during dynamic follow-up process.

[0093] In addition, a snap-fit ​​structure 500 includes multiple plugs 510. For example, as shown in the figure, the snap-fit ​​structure 500 includes two plugs 510. In the Z direction, the two plugs 510 are spaced apart, which balances the force on the mounting bracket 400, reduces local stress concentration, and extends the service life of the component.

[0094] The corresponding design of the insertion slot 101 and the insertion piece 510 ensures that the relative position of the mounting bracket 400 and the dimming bracket 100 is precise and controllable, avoiding the deviation of the light output direction of the projection lamp 300 and the low beam lamp 200 due to assembly errors, thereby ensuring the synchronization of the projected pattern with the illumination range of the AFS headlight.

[0095] The plug-in connection between the slot 101 and the connector 510 requires no complex tools or threaded fastening, reducing assembly difficulty and improving production efficiency. It also supports quick disassembly, facilitating later maintenance or upgrades to the projection lamp 300 module. The shape matching between the slot 101 and the connector 510 prevents misalignment of the mounting bracket 400, reducing the risk of human error during assembly.

[0096] In one possible implementation, at least one connector 510 is provided with a guide 520 in the width direction. Specifically, in the Y direction of the connector 510, the guide 520 is provided on one side of the connector 510.

[0097] The dimming bracket 100 is provided with a corresponding guide groove 102, and the guide member 520 is inserted into the corresponding guide groove 102.

[0098] A guide 520 can be provided on one side of the connector 510 in the Y direction. Alternatively, a guide 520 can be provided on each side of the connector 510 in the Y direction. The guide 520 extends in the X direction, which is the direction in which the connector 510 is inserted into the connector slot 101. The guide 520 moves along the guide groove 102 of the dimming bracket 100, providing a clear lateral limit and movement trajectory for the mounting bracket 400, ensuring that the projection lamp 300 maintains parallel light output with the low beam lamp 200 when the dimming bracket 100 rotates. The cooperation between the guide 520 and the guide groove 102 guides the connector 510 during insertion, reducing assembly difficulty and preventing assembly failure due to misalignment of the connector 510. This is especially suitable for scenarios where multiple connectors 510 are assembled in parallel.

[0099] The fault-tolerant design of the guide groove 102 can absorb minor dimensional deviations in manufacturing and assembly, ensuring that the connector 510 smoothly enters the connector groove 101 and improving the overall assembly accuracy.

[0100] In one possible implementation, the snap-fit ​​structure 500 further includes an elastic buffer 530 that abuts against the dimming bracket 100.

[0101] In the above embodiments, the elastic buffer 530 can be arranged in an arc shape. The arc-shaped elastic buffer 530 has a certain deformation capacity, which means that the elastic buffer 530 has a certain energy absorption capacity, which can further alleviate vibration and impact, reduce abnormal noise caused by component friction or collision, and further improve the comfort of use.

[0102] Continue to refer to Figure 8 and Figure 9 As shown, in one possible implementation, the mounting bracket 400 is provided with a snap-fit ​​groove 402.

[0103] The projection lamp 300 is provided with multiple snap-fit ​​parts 301, which can be close to or far from each other, and the snap-fit ​​parts 301 are inserted into the snap-fit ​​groove 402; the end of the snap-fit ​​part 301 is provided with a snap-fit ​​connector 302, which abuts against the surface of the mounting bracket 400 away from the projection lamp 300.

[0104] Here, the locking parts 301 can move closer or further apart, allowing the projection lamp 300 to be adjusted during assembly through elastic deformation or displacement to compensate for manufacturing tolerances or installation deviations. This ensures that the light output direction of the projection lamp 300 is strictly parallel to that of the low beam lamp 200, improving imaging accuracy. The locking connector 302 abuts against the surface of the mounting bracket 400 away from the projection lamp 300, using material elasticity or friction to form a self-locking mechanism, preventing loosening due to vibration, while retaining fine-tuning space to adapt to dynamic follow-up requirements.

[0105] Furthermore, the snap-fit ​​part 301 passes through the snap-fit ​​groove 402, enabling the connection between the projection lamp 300 and the mounting bracket 400 without the need for complex tools, thus reducing assembly difficulty; it also supports quick disassembly, facilitating later maintenance or replacement of the projection lamp 300 module. The range of motion of the snap-fit ​​part 301 is limited by the snap-fit ​​groove 402, preventing misalignment or excessive deformation during assembly and improving production efficiency.

[0106] In one possible implementation, this application provides a vehicle 20, including a body and at least one of the aforementioned headlight assemblies 10. The structure of the headlight assembly 10 has been described in detail above and will not be repeated here. This vehicle 20 possesses the technical effects of the aforementioned headlight assembly 10. When driving on a curve, the projection lamp 300, along with the low beam headlight 200, points synchronously to the inside of the curve, thus expanding the effective illumination range of the low beam headlight 200 while ensuring that the projected pattern remains within the driver's field of vision, balancing functionality and aesthetics, and enhancing the user experience.

[0107] In this embodiment, vehicle 20 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle, and the new energy vehicle can be a pure electric vehicle, a hybrid electric vehicle, or a range-extended electric vehicle, etc. This embodiment does not limit the specific structure of vehicle 20.

[0108] In this application embodiment, vehicle 20 can also refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, vehicle 20 in this application embodiment can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Of course, it can also be other types of vehicles 20; this application embodiment does not limit this. In the above embodiments,

[0109] The implementation principle of a vehicle headlight assembly 10 and a vehicle 20 according to an embodiment of this application is as follows: This embodiment provides a vehicle headlight assembly 10 and a vehicle 20. In this technical solution, the vehicle headlight assembly 10 includes a dimming bracket 100, a low beam headlight 200, and a projection lamp 300. The dimming bracket 100 is rotatably mounted on the vehicle body. The low beam headlight 200 is mounted on the dimming bracket 100 and emits light in a direction away from the dimming bracket 100. The projection lamp 300 is mounted on the dimming bracket 100, and its light emission direction is parallel to that of the low beam headlight 200. When the vehicle 20 turns, the dimming bracket 100 drives the projection lamp 300 and the low beam headlight 200 to adjust their illumination directions synchronously, ensuring that the image of the projection lamp 300 is always consistent with the driving direction of the vehicle 20, avoiding projection offset or distortion problems caused by a fixed position.

[0110] The projection lamp 300 and the low beam lamp 200 emit light in parallel directions, ensuring the stability of the projected pattern (such as a logo or light carpet) on the road surface and preventing the projection from deviating from the target area due to the vehicle turning. This dynamic adjustment capability enhances the practicality of nighttime vehicle location and road illumination functions, while also increasing the sense of technology and ceremony. When driving on curves, the projection lamp 300 and the low beam lamp 200 are simultaneously pointed towards the inside of the curve, expanding the effective illumination range of the low beam lamp 200 while ensuring that the projected pattern remains within the driver's field of vision, balancing functionality and aesthetics, and improving the user experience.
