Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobiles, in particular to a headlamp assembly and a vehicle. BACKGROUND

[0002] In order to realize these diversified light modes, the conventional headlamp usually adopts multiple independent light-emitting modules to correspond to different functions respectively. Each module occupies a specific spatial position in the lamp body, and the mode switching is realized by individually controlling the lighting and extinguishing of each module. However, this design idea of "one mode one module" has obvious limitations in practical application. On the one hand, since the physical positions of each module are fixed, their irradiation areas are relatively concentrated, and the light beam coverage range is limited, making it difficult to achieve high uniformity of the illumination effect. On the other hand, when the vehicle manufacturer wants to realize differentiated light modeling or light effect on different vehicle models, it is often necessary to rearrange the internal structure of the headlamp or even redesign the entire optical system and structure, which not only prolongs the development cycle, but also significantly increases the mold cost, verification cost and software and hardware adaptation cost, seriously restricting the platform development and vehicle iteration efficiency. SUMMARY

[0003] The present application aims to at least solve one of the technical problems existing in the prior art. To this end, the present application proposes a headlamp assembly, which has a wide irradiation range and good adjustability, which is beneficial to save the development cost of automobile manufacturers.

[0004] The present application also proposes a vehicle comprising the above-mentioned headlamp assembly.

[0005] According to the headlamp assembly of the first aspect of the present application, at least three light-emitting modules are provided, each of which comprises an optical assembly and at least two light sources. In the same light-emitting module, the light emitted by any light source can be directed to the optical assembly. The optical assembly is used to reflect and / or refract the light from the light source. The headlamp assembly has a first light mode, a second light mode and a third light mode. When the headlamp assembly is in any one of the first light mode, the second light mode and the third light mode, at least two light-emitting modules emit light. And any two modes of the first light mode, the second light mode and the third light mode satisfy that the light sources in the light-emitting state are not completely the same, and several light sources are shared.

[0006] According to the headlamp assembly of the first aspect of the present application, at least the following beneficial effects are achieved: In the prior art, in order to integrate multiple functions into a headlamp, the headlamp has multiple modules. For example, if the headlamp is required to have three light modes, the headlamp in the prior art usually has three light-emitting modules. For example, the three light modes are a daytime running light mode, a low beam light mode and a high beam light mode, and the three light-emitting modules are a daytime running light module, a low beam light module and a high beam light module. If the high beam light mode is switched to, only the daytime running light module emits light; if the daytime running light mode is switched to, only the low beam light module emits light; and if the low beam light mode is switched to, only the high beam light module emits light. However, the positions of these light-emitting modules are different, and the illumination area is narrow and the illumination effect is limited. Moreover, for automobile manufacturers, if multiple different vehicle models are developed and different light patterns or light effects are expected on different vehicle models, the light-emitting modules may need to be rearranged and the structure of the headlamp may need to be greatly adjusted in the design and manufacturing stages, which results in high development cost of the automobile.

[0007] However, for the headlamp assembly of the present embodiment, at least two light-emitting modules emit light when the headlamp assembly is in a single light mode, rather than only one light-emitting module, so that the illumination area of the headlamp assembly is wide and the illumination effect is good. Moreover, the adjustability of the headlamp assembly of the present embodiment is good, and if the automobile manufacturer needs to change the light pattern or the light effect, the automobile manufacturer can adjust the light sources that emit light and are extinguished in different light modes (which can be achieved by adjusting the software for controlling the headlamp assembly) without the need to rearrange the light-emitting modules and adjust the structure of the headlamp assembly, which greatly reduces the development cost of the automobile.

[0008] According to some embodiments of the present application, at least a part of the light-emitting modules includes a first light source and a second light source, at least one of the first light source and / or at least one of the second light source emits light when the headlamp assembly is in any one of the first light mode, the second light mode and the third light mode; at least a part of the light-emitting modules further includes a third light source, the third light source is different from the first light source and the second light source in terms of the color of the emitted light, and the headlamp assembly further has a fourth light mode, the third light source emits light when the headlamp assembly is in the fourth light mode.

[0009] According to some embodiments of the present application, when the headlamp assembly is in the fourth light mode, the first light source and the second light source are both extinguished, and / or the third light source flashes.

[0010] According to some embodiments of the present application, when the headlamp assembly is in the fourth light mode, at least one of the first light source and / or at least one of the second light source emits light, and the third light source is always on.

[0011] According to some embodiments of the present application, the first light mode is a daytime running light mode, the second light mode is a low beam light mode, and the third light mode is a high beam light mode; at least one of the light emitting modules comprises a fog light source, and the headlamp assembly further comprises a fog light mode, when the headlamp assembly is in the fog light mode, the fog light source emits light; each of the light emitting modules comprises a third light source, the third light source is different from the first light source and the second light source in terms of color of emitted light, and the headlamp assembly further comprises a turn signal light mode, when the headlamp assembly is in the turn signal light mode, the third light source emits light; each of the light emitting modules comprises a fourth light source, the fourth light source is different from the first light source, the second light source and the third light source in terms of color of emitted light, and the headlamp assembly further comprises an auxiliary driving indication mode, when the headlamp assembly is in the auxiliary driving indication mode, the fourth light source emits light.

[0012] According to some embodiments of the present application, the headlamp assembly comprises a mounting base and a light-transmitting lampshade, the mounting base is detachably connected with the lampshade and defines a cavity, and the light emitting modules are located in the cavity.

[0013] According to some embodiments of the present application, the optical assembly comprises a reflector bowl for reflecting light and making the light pass through the lampshade and exit; and / or, the light emitting modules further comprise thick-wall light guide members located between the lampshade and the light sources.

[0014] According to some embodiments of the present application, the light emitting modules are arranged from left to right in a front-to-back view.

[0015] According to some embodiments of the present application, for the light sources shared by different modes, the light sources have different brightness in different modes.

[0016] The vehicle according to the second aspect of the embodiments of the present application comprises the vehicle door assembly according to the first aspect of the embodiments of the present application.

[0024] Figure 2A headlight assembly 101 according to one embodiment of the present invention is shown. The headlight assembly 101 includes four light-emitting modules 104, each light-emitting module 104 including an optical component and two light sources 106. Light emitted from any light source in the same light-emitting module can be directed towards the optical component. In other embodiments, the number of light-emitting modules 104 can be adjusted, as long as there are at least three light-emitting modules 104 and each light-emitting module 104 has at least two light sources 106. The headlight assembly 101 may include a lamp panel having multiple LED chips. The optical component is used to reflect and / or refract light from the light source. In this embodiment, the optical component includes a reflector bowl 105 for reflecting light from the light source, and the reflector bowl 105 and multiple LED chips constitute a light-emitting module 104. For example, in a first embodiment, the lamp panel has eight LED chips, and one reflector bowl 105 and two LED chips constitute a light-emitting module 104. In other embodiments, the optical component may also include lenses, thick-walled light guides, etc.

[0025] The headlight assembly 101 has a first lighting mode, a second lighting mode, and a third lighting mode. When the headlight assembly 101 is in any of the aforementioned three modes, at least two light-emitting modules 104 emit light. Here, emitting light from a light-emitting module 104 means that at least one light source 106 (e.g., an LED chip) in the light-emitting module 104 emits light. Furthermore, any two of the aforementioned three modes satisfy the following condition: the light sources 106 in the emitting state are not identical, and several of the light sources 106 are shared.

[0026] The following example uses daytime running light mode as the first lighting mode, low beam mode as the second lighting mode, and high beam mode as the third lighting mode to explain the working principle of the headlight assembly 101. Figure 2 As shown, the headlight assembly 101 includes four light-emitting modules 104, each of which includes two light sources 106. From left to right, these eight light sources 106 are light source 1, light source 2, light source 3, light source 4, light source 5, light source 6, light source 7, and light source 8.

[0027] When driving during the day, daytime running lights are typically required. The headlights can be switched to daytime running light mode at this time. When driving at night or in low-light conditions, low beam or high beam headlights are typically required. The headlights can be switched to high beam or low beam mode at this time. The driver can switch the operating modes of the headlight assembly 101 using buttons, levers, or other components in the cockpit, or by speaking the desired operating mode to the vehicle's infotainment system.

[0028] In daytime running light mode, light sources 1, 3, 5, and 7 emit light, and these four light sources 106 emit light continuously (in a constant-on state). At this time, all four light-emitting modules 104 emit light.

[0029] In low beam mode, light sources 2, 3, 5, and 7 emit light, and these four light sources 106 emit light continuously (in a constant-on state). At this time, all four light-emitting modules 104 are emitting light.

[0030] In high beam mode, light sources 3, 4, 5, and 6 emit light, and these four light sources 106 emit light continuously (in a constant-on state). At this time, only the two middle light-emitting modules 104 emit light.

[0031] Therefore, it is evident that the light sources 106 corresponding to high beam mode and daytime running light mode are not entirely the same (some are the same, but others are different). In both high beam mode and daytime running light mode, light sources 3, 5, and 7 are emitted; therefore, light sources 3, 5, and 7 are shared light sources 106 for both high beam and daytime running light modes. Similarly, light sources 3 and 5 are shared light sources 106 for both daytime running light and low beam modes.

[0032] To facilitate the explanation of the technical effects of this embodiment, a headlight in the prior art is briefly introduced below. In the prior art, to integrate multiple functions, headlights have multiple modules. For example, if a headlight is to have high beam, daytime running light, and low beam modes, then a headlight in the prior art typically has three light-emitting modules: a daytime running light module, a low beam module, and a high beam module. To switch to daytime running light mode, only the daytime running light module illuminates; to switch to low beam mode, only the low beam module illuminates; and to switch to high beam mode, only the high beam module illuminates. However, these light-emitting modules are located in different positions, resulting in a narrow illumination area and limited lighting effect. Furthermore, for automakers, if they need to develop multiple different car models and expect different headlight designs or effects on different models, they may need to rearrange the various light-emitting modules during the design and manufacturing stages, potentially requiring significant structural adjustments to the headlights, which would lead to excessively high vehicle development costs. Among them, headlight design refers to the shape of the luminous area seen when looking at the headlight itself when it is emitting light.

[0033] In this embodiment, when the headlight assembly 101 is in a single light mode, at least two light-emitting modules 104 emit light, rather than only one light-emitting module 104. Therefore, the headlight assembly 101 has a wider illumination area and better lighting effect. Moreover, the headlight assembly 101 in this embodiment has good adjustability. If the automaker needs to change the headlight shape or lighting effect, the automaker does not need to rearrange the individual light-emitting modules 104 and adjust the structure of the headlight assembly 101. Instead, the automaker can simply adjust the light sources 106 that emit light and turn off in different light modes (this can be achieved by adjusting the software that controls the headlight assembly 101), which greatly reduces the cost of automobile development.

[0034] In some embodiments, at least a portion of the light-emitting module 104 includes a first light source 107 and a second light source 108. When the lighting assembly 101 is in any one of a first lighting mode, a second lighting mode, and a third lighting mode, at least one first light source 107 and / or at least one second light source 108 emits light. For example, as... Figure 2 As shown, light sources 1, 3, 5, and 7 are the first light sources 107 of the four light-emitting modules 104, and light sources 2, 4, and 6 are the second light sources 108 of the first to third (from left to right) light-emitting modules 104. Which light sources 106 emit light in the first to third lighting modes has been illustrated earlier and will not be repeated here.

[0035] At least a portion of the light-emitting module 104 also includes a third light source 110, which emits light in a color that differs from both the first light source 107 and the second light source 108. The headlight assembly 101 also has a fourth lighting mode, in which the third light source 110 emits light.

[0036] For example, such as Figure 2 As shown, the fourth light-emitting module 104 includes a first light source 107 and a third light source 110. In some embodiments, the fourth lighting mode can be a fog light mode, where the first light source 107 and the second light source 108 emit white light, and the third light source 110 emits yellow light (yellow light has better penetration in dense fog). In the fourth lighting mode, the third light source 110 ( Figure 2 The light source (number 8 in the image) emits light.

[0037] For example, such as Figure 3As shown, in some embodiments, each light-emitting module 104 has a first light source 107, a second light source 108, and a third light source 110. The fourth lighting mode is a turn signal mode. The first light source 107 and the second light source 108 emit white light, and the third light source 110 emits orange-yellow light. When the driver needs to turn and alert surrounding vehicles and pedestrians, the driver can toggle the vehicle's turn signal lever, and the vehicle's control system will switch the headlight assembly 101 to turn signal mode. When the headlight assembly 101 is in turn signal mode, the third light source 110 can flash to make the turn signal noticeable to surrounding vehicles and pedestrians. In addition, when the headlight assembly 101 is in turn signal mode, the first light source 107 and the second light source 108 can both be turned off to prevent the brightness of the first light source 107 and the second light source 108 used by the high beam and low beam from being too high and affecting the visibility of the turn signal.

[0038] For example, the third light source 110 emits a light blue light. When the driver activates the vehicle's driver assistance function, the vehicle's control system can switch the headlight assembly 101 to the driver assistance alert mode, thereby alerting surrounding vehicles and pedestrians that the vehicle's driver assistance function has been activated. Since the vehicle's driver assistance function typically operates for extended periods, any of the first to third lighting modes can operate simultaneously with the fourth mode. That is, when the headlight assembly 101 is in the fourth lighting mode, at least one first light source 107 and / or at least one second light source 108 are illuminated, and the third light source 110 remains constantly lit. This configuration ensures that the headlight assembly 101 can still illuminate the road ahead of the vehicle when driver assistance is activated.

[0039] In some embodiments, the headlight assembly 101 can simultaneously provide daytime running light mode, low beam mode, high beam mode, fog light mode, turn signal mode, and driver assistance indication mode. This configuration allows the headlight assembly 101 to integrate multiple functions. Specifically, as... Figure 3 As shown, each light-emitting module 104 includes a third light source 110. The third light source 110 emits a different color than both the first light source 107 and the second light source 108. The headlight assembly 101 also has a turn signal mode; when the headlight assembly 101 is in turn signal mode, the third light source 110 emits light. Each light-emitting module 104 also includes a fourth light source 111. The fourth light source 111 emits a different color than both the first light source 107, the second light source 108, and the third light source 110. The headlight assembly 101 also has a driver assistance indicator mode; when the headlight assembly 101 is in driver assistance indicator mode, the fourth light source 111 emits light. At least a portion of the light-emitting modules 104 include a fog light source 109. The headlight assembly 101 also has a fog light mode; when the headlight assembly 101 is in fog light mode, the fog light source 109 emits light. Figure 3Fog light source 109 is not shown in the diagram. Fog light source 109 can be located in... Figure 3 The rightmost light-emitting module 104.

[0040] like Figure 1 As shown, the headlight assembly 101 includes a mounting base 102 and a light-transmitting lamp cover 103. The mounting base 102 and the lamp cover 103 are detachably connected (e.g., by snap-fit, screw connection, etc.), and together they define a cavity in which the light-emitting module 104 is located. Each light-emitting module 104 includes a reflector 105. All light sources 106 in the same light-emitting module 104 face the reflector 105 and are able to emit light into the reflector 105. The reflector 105 is used to reflect the light and allow it to pass through the lamp cover 103 and be emitted. The reflector 105 is used to reflect light, thereby improving the light emission efficiency of the headlight assembly 101.

[0041] In some embodiments, the lamp panel 112 may be placed horizontally, the light source 106 may be vertically upward, and the reflector bowl 105 may be positioned forward and cover the light source 106 (e.g., Figure 4 As shown in (a). In some other embodiments not shown, the lamp panel 112 may also be vertical, with the light source 106 facing forward and the reflector bowl 105 facing forward and surrounding the outer periphery of the light source 106 (e.g., Figure 4 (as shown in (b)).

[0042] like Figure 5 As shown, in some embodiments, the headlight assembly 101 further includes a thick-walled light guide 113 located between the lamp cover 103 and the reflector bowl 105. The thick-walled light guide 113 is used to conduct light and enhance illumination and make the light more uniform.

[0043] It should be noted that all light sources 106 in the same light-emitting module 104 do not necessarily need to be distributed in a straight line. They can be distributed in a rectangular array, a circular array, or other irregular distribution patterns. Different light sources 106 have different positions relative to the reflector bowl 105, and the angle at which their emitted light is reflected by the reflector bowl 105 may also be different. The desired illumination angle or illumination range can be obtained by adjusting the position of the light source 106 relative to the reflector bowl 105. For example, the illumination angle of the high beam is higher than that of the low beam. Light sources 4 and 6, which emit light in high beam mode, are positioned differently from light sources 3 and 5, which emit light in low beam mode. This allows the high beam illumination angle to be different from that of the low beam.

[0044] In some embodiments, when viewed from a front-to-back perspective, multiple light-emitting modules 104 are arranged from left to right. In this configuration, when the headlight assembly 101 is in any of the first, second, or third lighting modes, at least two light-emitting modules 104 emit light, and the headlight assembly 101 has a wide illumination area in the left-right direction.

[0045] In some embodiments, the brightness of the shared light source 106 varies in different modes. The brightness of the light source 106 can be controlled by the vehicle's control system, which determines the required lighting mode and then adjusts the brightness of the light source 106 according to a preset program.

[0046] The following example illustrates that "the brightness of light source 106 varies in different modes." As mentioned above, in daytime running light mode, light sources 1, 3, 5, and 7 emit light; in low beam mode, light sources 2, 3, 5, and 7 emit light. Light sources 3, 5, and 7 are shared by both modes. Low beam mode requires greater brightness than daytime running light mode. Therefore, in daytime running light mode, the brightness of light sources 3, 5, and 7 can be set relatively low; while in low beam mode, the brightness of light sources 3, 5, and 7 can be set relatively high.

[0047] Similarly, for both low beam and high beam modes, light sources 3 and 5 are shared by both modes (106). The high beam can be brighter than the low beam to efficiently illuminate the road ahead. In low beam mode, the brightness of light sources 3 and 5 can be set relatively low; while in high beam mode, the brightness of light sources 3 and 5 can be set relatively high.

[0048] It should be noted that, in the three modes mentioned above, the light sources 106 can be combined in other ways. For example, in daytime running light mode, light sources 1, 4, 6, and 8 emit light; in low beam mode, light sources 2, 4, 5, and 6 emit light. Not all feasible combinations are listed here, as long as the following conditions are met: "when the headlight assembly 101 is in any one of the first, second, or third lighting modes, at least two light-emitting modules 104 emit light," and "any two of the first, second, and third lighting modes satisfy the condition that the light sources 106 in the emitting state are not completely identical, and several light sources 106 are shared."

[0049] Furthermore, the first, second, and third lighting modes are not limited to the modes listed above. The specific modes referred to by each lighting mode can also be reselected and rearranged from all the specific modes listed above (daytime running light mode, low beam mode, high beam mode, fog light mode, turn signal mode, and driver assistance indicator mode, etc.), and are not limited to the first, second, and third lighting modes being daytime running light mode, low beam mode, and high beam mode, respectively.

[0050] The aforementioned headlight assembly 101 can be used in vehicles. Vehicles can be private cars, such as sedans, SUVs, MPVs, or pickup trucks. Vehicles can also be commercial vehicles, such as vans, buses, small trucks, or large semi-trailers. Vehicles can be either gasoline-powered or new energy vehicles. When a vehicle is a new energy vehicle, it can be a hybrid or a pure electric vehicle.
