[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0045] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections, electrical connections, or mutual communication; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0046] The vehicle lamp assembly and the vehicle in this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] In the prior art, the arrangement positions of the functional lamps in the integrated headlights are unreasonable, which is not conducive to the stability of the headlights and the lighting effect of the headlights is poor.

[0048] The present application provides an automotive lamp assembly comprising a bracket, a light guide module, and a dimming module. The light guide module comprises four spaced-apart light guide components mounted on the bracket, with their adjacent edges forming a cross-shaped mounting area. In a three-dimensional coordinate system, the four light guide components are configured to emit light along a Y-axis parallel to the main light-emitting direction of the automotive lamp assembly. The dimming module is mounted on the bracket in the mounting area and is configured to adjust the light and direct the adjusted light along the Y-axis to the light-emitting side of the bracket. The dimming module weighs more than the light guide module. This is described in detail below.

[0049] See Figure 1 and Figure 2 The headlight assembly includes a bracket 10, a light guide module and a dimming module 40; the light guide module includes four light guide components 20 arranged at intervals, the light guide components 20 are arranged on the bracket 10, and the edges of the light guide components 20 close to each other form a cross-shaped installation area 30; in the three-dimensional coordinate system, the four light guide components 20 are configured to emit light along the Y-axis direction, and the Y-axis direction is parallel to the main light-emitting direction of the headlight assembly; the dimming module 40 is arranged on the part of the bracket 10 located in the installation area 30, and the dimming module 40 is configured to adjust the light and guide the adjusted light along the Y-axis direction to the light-emitting side of the bracket 10; the weight of the dimming module 40 is greater than the weight of the light guide module.

[0050] By arranging four light-guiding components 20 and a dimming module 40 on the bracket 10, the same headlight can achieve lighting effects of multiple functions, that is, multiple functions can be integrated into one headlight; when the lamps of each function are arranged separately, a large space will be occupied for related installation and arrangement. Integrating them into one headlight reduces space occupation, which is beneficial to the design of the vehicle shape to meet the diversity of design; and during the assembly process, only one headlight needs to be installed, which improves the assembly efficiency and avoids the complexity of the assembly process affecting the assembly quality.

[0051] The edges of the four light-guiding components 20 that are close to each other form a cross-shaped installation area 30, and the installation area 30 is located in the middle part of the entire headlight. The dimming module 40 is arranged in the installation area 30, that is, the dimming module 40 is arranged in the middle part of the entire headlight; since the dimming module 40 itself is heavy, such an arrangement is beneficial to the distribution of the overall weight of the headlight, that is, the center of gravity of the entire headlight is close to the middle part, which is beneficial to the stability of the headlight installed on the vehicle.

[0052] When the weight of a headlight is unevenly distributed, the mounting parts of the headlight on the vehicle are unevenly stressed. Under the vibration or external force of the vehicle during driving, the part of the headlight that is mounted on the vehicle is easily damaged, which reduces the service life of the headlight and easily generates noise, affecting the driving experience of the driver and passengers.

[0053] It is worth mentioning that the cross-shaped installation area 30 has a regular structure, the static visual effect of the headlight is good, the positions of the various functions are reasonably arranged, and the lighting effect when the headlight is turned on is good.

[0054] It should be noted that a mounting hole 12 is provided in the portion of the bracket 10 located in the mounting area 30 , and the dimming module 40 is disposed in the mounting hole 12 .

[0055] In some embodiments, the dimming module 40 includes a first dimming component 41, a second dimming component 42 and a third dimming component 43 arranged in sequence along the Z-axis direction, and the Z-axis direction is configured as the opposite direction of gravity; the second dimming module is set in the intersection area of ​​the installation area 30.

[0056] In this embodiment, the first dimming component 41, the second dimming component 42 and the third dimming component 43 each correspond to a vehicle light function, thereby increasing the diversity of vehicle light lighting functions; the second dimming component 42 is disposed at the intersection of the mounting area 30, and the third dimming component 43 is disposed above the second dimming component 42 ( Figure 1 The first dimming component 41 is arranged below the second dimming component 42 ( Figure 1 The dimming components of the dimming module 40 (the first dimming component 41, the second dimming component 42 and the third dimming component 43) are arranged in reasonable positions and have a uniform weight distribution, which is beneficial to improving the stability of the lamp installation.

[0057] In some embodiments, the third dimming component 43 is a brake light, that is, the brake light is arranged in the upper half of the headlight, that is, the brake light is arranged at a higher position when installed on the vehicle, which can be easily observed by the following vehicles, and the following vehicles can respond in time to avoid traffic accidents due to failure to observe the brake light in time.

[0058] In some embodiments, the first dimming component 41 is a reversing light. The first dimming component 41 is arranged at a lower position. When used for reversing, the light emitted by the first dimming component 41 is at a lower position, which can better illuminate the ground and rear space behind the vehicle, thereby improving the safety of reversing.

[0059] In some embodiments, the light guide 20 is a position light, and is integrated with the bracket 10. This allows for the integration of lights with different functions, reduces dimensional accuracy issues caused by machining errors caused by multiple parts, and ensures consistent assembly of the lamp, as well as production efficiency and yield. This integrated design reduces the number of connecting parts between the various components (the light guide 20 and the bracket 10), lowering production costs while reducing the weight of the lamp, facilitating lightweight vehicle design, and reducing assembly strength.

[0060] It is worth mentioning that the integrated setting also improves the visual effect of the headlights when they are static. The integrated setting reduces the connection structure between the components, can block the light-entering side, and improve the quality of the headlights.

[0061] See Figure 8 and Figure 9 In some embodiments, the vehicle lamp assembly includes a housing 60, a photometric lens 70, and a bracket 10; the photometric lens 70 is covered on the housing 60 to form a cavity 80, and a first shielding protrusion 71 is provided around the edge of the light-entering side of the photometric lens 70, and the first shielding protrusion 71 is located in the cavity 80; the bracket 10 is accommodated in the cavity 80, and a second shielding protrusion 11 is provided around the edge of the light-emitting side of the bracket 10; a projection plane γ perpendicular to a reference direction is set, and the orthographic projections of the first shielding protrusion 71 and the second shielding protrusion 11 on the projection plane γ are adjacent to or at least partially overlapped with each other, and the reference direction is parallel to the reflected light at the connection between the housing 60 and the photometric lens 70.

[0062] The orthographic projections of the first blocking protrusion 71 and the second blocking protrusion 11 on the projection surface γ are adjacent to or at least partially overlapped with each other, that is, there is no gap between the orthographic projections of the two, and no reflected light will be directed to the light-emitting side of the photosensitive lens 70, that is, the connection between the shell 60 and the photosensitive lens 70 will not be observed on the light-emitting side of the photosensitive lens 70.

[0063] By cooperating with the first blocking protrusion 71 and the second blocking protrusion 11, the connection between the shell 60 and the light distribution mirror 70 can be blocked. When observing the headlight from the light-emitting side of the light distribution mirror 70, the connection between the shell 60 and the light distribution mirror 70 cannot be observed, thereby improving the static visual effect of the headlight.

[0064] In this embodiment, the photometric lens 70 is an external photometric lens, and the shell 60 and the photometric lens 70 are connected by welding. The first shielding protrusion 71 and the second shielding protrusion 11 can shield the welding slag and the structure used for welding between the shell 60 and the photometric lens 70; when observing the inside of the headlight through the external photometric lens, the welding slag and the structure used for welding are shielded by the first shielding protrusion 71 and the second shielding protrusion 11, which improves the static visual effect of the headlight and makes the headlight more beautiful.

[0065] It should be noted that the connection between the shell 60 and the lens 70 in this embodiment refers to the structure used for welding and the welding slag formed by welding. In some embodiments, it can also refer to other connection forms, such as related structures bonded by glue, etc., but it is not limited to this; the reflected light at the connection between the shell 60 and the lens 70 will be observed after entering the human eye, and the light irradiated at the connection between the shell 60 and the lens 70 is reflected to form the reflected light. The first blocking protrusion 71 and the second blocking protrusion 11 block the reflected light, that is, to avoid observing the reflected light (the connection between the shell 60 and the lens 70) from the light-emitting side of the external lens (lens 70).

[0066] It is worth mentioning that the direction of the reflected light at the connection between the shell 60 and the photometric mirror 70 is not unique, that is, the direction of the reference direction is not unique, that is, the projection surface γ is not unique. From multiple angles of the light-emitting side of the photometric mirror 70, the connection between the shell 60 and the photometric mirror 70 cannot be seen.

[0067] In addition, the first blocking protrusion 71 is set on the edge of the light-incoming side of the light distribution lens 70, and the second blocking protrusion 11 is set on the edge of the light-outgoing side of the bracket 10. The two (the first blocking protrusion 71 and the second blocking protrusion 11) will not hinder the overall light propagation of the car lamp, which is conducive to improving the lighting effect.

[0068] The first shielding protrusion 71 is disposed around the second shielding protrusion 11 ; or, the second shielding protrusion 11 is disposed around the first shielding protrusion 71 .

[0069] In this embodiment, Figure 9 Take the viewing angle as an example for explanation; the first blocking protrusion 71 is arranged around the second blocking protrusion 11, that is, the first blocking protrusion 71 is arranged on the outside of the second blocking protrusion 11, that is, the first blocking protrusion 71 is arranged on the right side of the second blocking protrusion 11 (the first blocking protrusion 71 and the second blocking protrusion 11 are laterally spaced apart). When the light distribution mirror 70 is installed on the housing 60, there will be no interference between the first blocking protrusion 71 and the second blocking protrusion 11, which is conducive to improving the installation convenience between the housing 60 and the light distribution mirror 70.

[0070] In some embodiments, the second blocking protrusion 11 can also be arranged around the first blocking protrusion 71; or the ends of the first blocking protrusion 71 and the second blocking protrusion 11 can be arranged relative to each other, but not limited to this, as long as it can ensure that the first blocking protrusion 71 and the second blocking protrusion 11 cooperate with each other to block the connection between the shell 60 and the light distribution lens 70.

[0071] It is worth mentioning that compared with the opposite arrangement of the ends of the first shielding protrusion 71 and the second shielding protrusion 11, when the first shielding protrusion 71 and the second shielding protrusion 11 are arranged horizontally at intervals, the longitudinal size of the headlight assembly can be effectively reduced, the longitudinal space occupied is reduced, and it is beneficial to the arrangement of other components.

[0072] In some embodiments, the first shielding protrusion 71 and the second shielding protrusion 11 can be arranged to fit together, and the arrangement can be performed according to the actual structure and size of the vehicle lamp.

[0073] In some embodiments, the first blocking protrusion 71 abuts against the second blocking protrusion 11 .

[0074] In this embodiment, the first shielding protrusion 71 and the second shielding protrusion 11 abut against each other, that is, there is no gap between the first shielding protrusion 71 and the second shielding protrusion 11. The abutment between the two can improve the stability between the photochromic lens 70 and the bracket 10, and the welding slag generated by the welding of the photochromic lens 70 and the shell 60 will not enter the part of the photochromic lens 70 used for light transmission, thereby improving the lighting effect of the car lights.

[0075] It should be noted that the dimming components in the dimming module 40 are thick-walled parts, which is beneficial to improving the lighting effect of each functional lamp. The thick-walled parts are heavier and are set within the area of ​​the installation area 30, which is beneficial to the overall weight distribution of the car lamp. In addition, the function of the light-guiding component 20 is equivalent to the inner mirror. When installed in the car lamp for use, the light is emitted through the inner mirror (light-guiding component 20) and the outer mirror (light-distributing mirror 70) in turn.

[0076] In some embodiments, the dimming module further includes a fourth dimming component 44 , which is spaced apart and disposed on a side of the first dimming component 41 away from the second dimming component 42 .

[0077] The fourth dimming component 44 is disposed below the first dimming component 41 ( Figure 1 angle of view), increasing the weight of the bottom of the lamp is beneficial to improving the stability of the lamp installation; when the fourth dimming component 44 is arranged above the lamp ( Figure 1 The third dimming component 43 is arranged above the third dimming component 43), the entire headlight will appear top-heavy. Under the vibration or external force during the driving process of the vehicle, the top of the headlight will tend to rotate downward, which is not conducive to the stability of the entire headlight.

[0078] In this embodiment, the fourth dimming component 44 is arranged at a position (below the first dimming component 41), and the headlight as a whole will appear top-light and foot-heavy, similar to the principle of a plumb bob, and the headlight will be more stable.

[0079] It is worth mentioning that the provision of the fourth dimming component 44 further enhances the diversity of the functions of the headlights. By arranging dimming components with multiple functions in the limited space of the headlights, the diversity of the use of the headlights is enhanced and the space occupied by the headlights is reduced.

[0080] In some embodiments, the vehicle lamp assembly further includes a heat sink 50 , the fourth dimming component 44 is configured as a fog lamp, the heat sink 50 is disposed on the light incident side of the fourth dimming component 44 , and is configured to take away the heat emitted by the fourth dimming component 44 .

[0081] The fog lamp requires a strong penetration force, so the fog lamp will generate more heat. The setting of the radiator 50 can take away the heat generated by the fog lamp in time, thereby improving the service life of the fourth dimming component 44; at the same time, the setting of the radiator 50 increases the weight of the bottom of the lamp, which is beneficial to improving the stability of the lamp installation. For detailed analysis, please refer to the above embodiment and will not be repeated here.

[0082] See Figure 3-6 The headlight assembly also includes a shell 60 and a photometric lens 70. The photometric lens 70 covers the opening of the shell 60 to form a cavity 80. The bracket 10 is accommodated in the cavity 80 through the mounting bracket 140. The photometric lens 70 is spaced apart on the light-emitting side of the bracket 10. The inner wall of the cavity 80 around the Y-axis direction is spaced apart from the circumference of the bracket 10 and the circumference of the mounting bracket 140. The inner wall of the shell 60 facing the photometric lens 70 is provided with an air inlet 61 and an air outlet 62. The air inlet 61 and the air outlet 62 are spaced apart along the Z-axis direction.

[0083] In this embodiment, the peripheral sides of the bracket 10 and the peripheral sides of the mounting frame 140 are spaced apart from the inner wall of the shell 60, that is, an air flow channel 90 is formed on the peripheral sides of the bracket 10 and the mounting frame 140. The heat on the light incident side of the bracket 10 can flow through the air flow channel 90 to the space between the bracket 10 and the light distribution mirror 70 (the bracket 10 and the light distribution mirror 70 are spaced apart), that is, the air flow channel 90 connects the light incident side and the light output side of the bracket 10.

[0084] In addition, an air inlet 61 is provided at the bottom of the housing 60, and an air outlet 62 is provided at the top of the housing 60. According to the principle of thermodynamics, the heat generated on the light-entering side of the bracket 10 will be directed to the top of the headlight (such as Figure 3 As shown in the figure, the dotted arrow indicates the direction of gas flow), a pressure difference is formed on the inside and outside of the air inlet 61, that is, air will flow from the outside of the headlight into the inside of the headlight through the air inlet 61, so that the heat under the headlight flows upward and dissipates through the air outlet 62. The air outside and inside the headlight can circulate, thereby taking away the heat inside the headlight, with high heat dissipation efficiency and simple structure.

[0085] It is worth mentioning that in some embodiments, the bracket 10 (and the mounting bracket 140) can be spaced apart from the inner wall of the shell 60 at only the upper and lower ends, that is, air flow channels 90 are formed at the upper and lower ends of the bracket 10, which can also realize the circulation of air flow inside the car lamp, and the rest of the bracket 10 can be connected to the shell 60 or the light distribution lens 70 to enhance the stability of the bracket 10, but it is not limited to this.

[0086] It should be noted that the circumferential side of the bracket 10 is the circumferential side of the bracket 10 around the Y-axis direction, and the circumferential side of the mounting frame 140 is the circumferential side of the mounting frame 140 around the Y-axis direction; in addition, other components arranged on the bracket 10 or the mounting frame 140 (such as the light guide component 20, the dimming module 40, etc.) will not affect the formation of the airflow channel 90.

[0087] In some embodiments, as Figure 3 As shown, the diameter of the air inlet end (left side) of the air outlet hole 62 is larger than the diameter of the air outlet end (right side), which can quickly discharge the heat inside the car lamp; at the same time, the air inlet hole 61 is arranged opposite the radiator 50 of the fog lamp. With this arrangement, the gas entering from the outside of the car lamp can be directly blown onto the radiator 50, thereby improving the heat dissipation efficiency of the radiator 50.

[0088] See Figure 8 The mounting frame 140 is arranged in the cavity 80, and the bracket 10 is covered on the mounting frame 140; the mounting frame 140 has a first mounting cavity 141 and a second mounting cavity 142 arranged at intervals, the dimming module 40 is arranged in the first mounting cavity 141, and the light guide component 20 is covered in the second mounting cavity 142; the part of the bracket 10 located in the mounting area 30 is provided with a mounting hole 12, the mounting hole 12 is arranged opposite to the first mounting cavity 141, and the light-emitting surface of the dimming module 40 passes through the mounting hole 12.

[0089] The first mounting cavity 141 and the second mounting cavity 142 on the mounting frame 140 can separate the light passing through the dimming module 40 from the light passing through the light guide component 20 , thereby preventing the light from interfering with each other and affecting the lighting effect of the vehicle lamp.

[0090] See Figure 10 A third shielding protrusion 13 is provided on the peripheral side of the mounting hole 12 located on the light incident side of the bracket 10, and a fourth shielding protrusion 1411 is provided on the end of the first mounting cavity 141 facing the bracket 10; a projection plane η perpendicular to the radial direction of the mounting hole 12 is set, and the third shielding protrusion 13 and the fourth shielding protrusion 1411 at least partially overlap between their positive projections on the projection plane η.

[0091] By cooperating with the third blocking protrusion 13 and the fourth blocking protrusion 1411, light can be blocked from passing through the gap between the bracket 10 and the mounting frame 140, thereby avoiding mutual interference between the first mounting cavity 141 and the second mounting cavity 142, thereby improving the lighting effect of the car lights.

[0092] The light emitting surface of the dimming module 40 and the light emitting surface of the light guide component 20 are spaced apart in the Y-axis direction.

[0093] When the dimming module 40 and the light guide component 20 are lit at the same time, since their light emitting surfaces are arranged at intervals, interference between the light emitted by the dimming module 40 and the light guide component 20 can be avoided, thereby improving the overall lighting effect.

[0094] like Figure 7 As shown, in some embodiments, the shell 60 is installed on the vehicle body through the mounting structure 100, wherein the mounting structure 100 includes a fixing portion 101 and a connecting plate 102, the fixing portion 101 is arranged on the side wall at the top of the shell 60 and the side wall on the right side of the shell 60, and the connecting plate 102 is arranged at the bottom of the shell 60. It only needs to be fixed in three directions of the shell 60 to achieve the installation of the car light (shell 60) on the vehicle body; there is no related mounting structure 100 on the left side of the shell 60, which provides design space for the external shape of the car light. The above-mentioned connecting plate 102 is arranged on the side of the bottom of the shell 60 that is biased to the left. Such an arrangement can have a certain limiting effect on the left side of the shell 60, which is beneficial to improving the installation stability of the car light.

[0095] It should be noted that the fixing portion 101 and the connecting plate 102 may be connected to the vehicle body by means of screws, rivets or the like.

[0096] In some embodiments, the shell 60 and the photochromic lens 70 are connected by a welding structure 110, and the welding structure 110 includes a first welding bump 111, a second welding bump 112 and a shielding portion 113. The first welding bump 111 is arranged on the peripheral side of the end face of the photochromic lens 70 facing the shell 60, the second welding bump is arranged on the peripheral side of the opening of the shell 60, and the shielding portion 113 is arranged in an interval ring on the peripheral side of the second welding bump 112; the first welding bump 111 is welded to the second welding bump 112, and the shielding portion 113 is spaced apart from the photochromic lens 70; taking the reference plane λ perpendicular to the Y-axis direction as the projection plane, the orthographic projection of the shielding portion 113 on the projection plane is located within the orthographic projection of the end face of the photochromic lens 70 facing the shell 60 on the projection plane.

[0097] The shielding portion 113 is disposed around the periphery of the second welding protrusion 112. When the first welding protrusion 111 and the second welding protrusion 112 are welded, the shielding portion 113 can shield the welding point between the first welding protrusion 111 and the second welding protrusion 112 (shielding welding slag), thereby improving the aesthetics of the headlight.

[0098] The shielding portion 113 is spaced apart from the end surface of the light distribution lens 70 facing the housing 60 (referred to as the first surface 130 for ease of explanation), that is, the shielding portion 113, the first welding protrusion 111, the second welding protrusion 112, and the first surface 130 form a water flow channel 120 with an opening. Water falling on the shielding portion 113 can enter the water flow channel 120 and flow to the bottom of the headlight under the guidance of the water flow channel 120 and be discharged; at the same time, the orthographic projection of the shielding portion 113 on the projection surface falls within the orthographic projection of the first surface 130 on the projection surface, that is, Figure 4 In the viewing angle, the shielding portion 113 is set lower than the first surface 130, and the water flow will be blocked by the first surface 130 and enter the water flow channel 120, but will not cross the first surface 130 to reach the light-emitting side of the photometric mirror 70, that is, it will not affect the lighting effect of the car light.

[0099] It should be noted that, in some embodiments, the shielding portion 113 does not have to be provided around the entire periphery of the lamp. The shielding portion 113 can be provided on the top and both sides of the lamp, and the bottom portion of the lamp does not need to be provided with the shielding portion 113 (e.g., Figure 5 As shown), when the headlight is installed on a vehicle, the welding slag at the bottom of the headlight cannot be seen, and no shielding portion 113 is provided at the bottom, which can facilitate the timely discharge of water from the water flow channel 120.

[0100] See Figure 2 The headlight assembly also includes a first printed circuit board 150 and a second printed circuit board 160. The first printed circuit board 150 and the second printed circuit board 160 are spaced apart in the Y-axis direction; the first printed circuit board 150 is configured to provide a light source to the light guide component 20, and the second printed circuit board 160 is configured to provide a light source to the dimming module.

[0101] The first printed circuit board 150 and the second printed circuit board 160 are spaced apart from each other to avoid mutual influence of heat generated therefrom, thereby effectively increasing the service life of the first printed circuit board 150 and the second printed circuit board 160 .

[0102] On the other hand, the present application also relates to a vehicle comprising any one of the aforementioned vehicle lamp assemblies.

[0103] The technical solution provided in the embodiment of the present application is intended to achieve lighting effects of multiple functions for the same headlight by arranging four light-guiding components 20 and a dimming module 40 on a bracket 10, and only one headlight needs to be installed, thereby improving assembly efficiency and avoiding the complexity of the assembly process that affects the assembly quality; the installation area 30 is located in the middle part of the entire headlight, and the dimming module 40 is arranged in the installation area 30, that is, the dimming module 40 is arranged in the middle part of the entire headlight; since the dimming module 40 itself is heavy, such an arrangement is beneficial to the distribution of the overall weight of the headlight, that is, the center of gravity of the entire headlight is close to the middle part, which is beneficial to the stability of the headlight installed on the vehicle.
