Description

Technical Field

[0001] The invention relates to a vehicle lighting device, a motor vehicle having a vehicle lighting device and a method for producing a vehicle lighting device. Background Art

[0002] Known motor vehicles, in particular land vehicles, usually include headlights, taillights and sidelights, which are part of the overall motor vehicle lighting system. Such motor vehicle lights are mainly used to improve the visibility of male / female drivers in the dark and to make the motor vehicle more conspicuous and can be designed in different ways, in particular according to the characteristic light signal characteristics for the respective motor vehicle.

[0003] Document DE 10 2004 028 970 A1 discloses a motor vehicle lamp known from the prior art. The vehicle lamp is configured as a signal lamp and is essentially composed of a light guide element, a light source and a coating. The light guide element has a light exit surface on its front side arranged in the emission direction and a reflection surface on its back side. The light coupled into the light guide element via the light coupling-in surface is further guided in the light guide element by total reflection, and the light incident on the reflection surface is deflected toward the light exit surface and exits from the light exit surface in the emission direction. Summary of the invention

[0004] Against this background, the object of the present invention is to provide a vehicle lighting device which can be produced relatively simply and cost-effectively with a relatively large cover plate and still meet high pedestrian protection requirements. In addition, the object of the present invention is to provide a corresponding motor vehicle and a corresponding method for producing a vehicle lighting device.

[0005] This object is achieved by a vehicle lighting device having the features of claim 1 , a motor vehicle according to claim 11 and a method according to claim 12 .

[0006] The vehicle lighting device can be configured as a motor vehicle lamp, in particular a headlight, and comprises a housing having a first housing part and a second housing part; and a cover plate device, the cover plate device having an integral cover plate, the cover plate having a first area that is at least partially light-transmissive and having a second area. The first housing part determines a first inner area covered by the first area of ​​the cover plate, and the second housing part determines a second inner area covered by the second area of ​​the cover plate. The cover plate device has a set breaking point at the boundary between the first area of ​​the cover plate and the second area of ​​the cover plate.

[0007] This arrangement of the breaking point makes it possible to design the cover plate to be relatively large to cover a large lamp chamber, and at the same time to provide a vehicle lighting device that is advantageous in terms of pedestrian safety. In particular, when a pedestrian accident occurs when a pedestrian hits the first or second area of ​​the cover plate, the cover plate can be broken at the above-mentioned boundary, so that the first area of ​​the cover plate can move relatively freely, in particular, separately from the second area of ​​the cover plate. The impact strength of the cut of the cover plate is reduced. This results in a smaller maximum force acting on the pedestrian and a smaller risk of pedestrian injury.

[0008] The terms "front / front side / front side" and "rear / back side / back side" used here can refer to the preferred installation position of the vehicle lighting device. That is to say, the cover plate can preferably be arranged on the front side and the housing can preferably be arranged on the back side.

[0009] In the context of the present disclosure, the term "at the boundary" (between the first and second regions of the closure plate) may refer to a position adjacent to the boundary. The position of the set breaking point determines the boundary. That is, if the set breaking point is (at least partially) formed in the closure plate, the boundary may extend through the set breaking point. If the set breaking point is formed in other components of the closure plate device, in particular in the support structure described below, the distance between the set breaking point and the first region may substantially correspond to the distance between the set breaking point and the second region.

[0010] The term "set breaking point" refers to a point determined by a predetermined structure, shape and / or design (e.g., a tapered portion of material) according to its general definition in the field of vehicle technology, which breaks foreseeably under a predetermined load. In particular, the set breaking point can be designed to break when a predetermined relative load is exceeded between the first and second areas of the cover plate, so that the first area is separated from the second area. That is to say, the part of the entire vehicle lighting device or the cover plate device that first breaks when the first area is pulled away from the second area, for example, parallel to the main surface of the cover plate, in a predetermined tensile test, can be called the set breaking point.

[0011] In addition to the closure plate, the closure plate device may also have a supporting structure, which may be arranged between the housing and the closure plate. The supporting structure and the closure plate preferably form together the closure plate device in the sense of the present disclosure. The setting of the breaking position may be partially or completely formed in the supporting structure. In addition, the setting of the breaking position may be partially or completely formed in the closure plate. In a preferred variant, the setting of the breaking position is not only formed in the supporting structure but also in the closure plate as explained in more detail below.

[0012] The supporting structure can mechanically connect the housing to the closure plate. In particular, the supporting structure can have a first connecting section, which contacts the first area of ​​the closure plate and the first housing part is connected to the first area of ​​the closure plate by means of the first connecting section. Similarly, the supporting structure can have a second connecting section, which contacts the second area of ​​the closure plate and the second housing part is connected to the second area of ​​the closure plate by means of the second connecting section. The supporting structure is preferably connected to the housing and / or the closure plate in a material-locked manner, and is most preferably injected (i.e., joined by injection molding) onto the closure plate and / or bonded or welded to the housing. The (back side) end of the supporting structure opposite to the closure plate can be accommodated in at least one groove formed in the housing, preferably extending along the circumference of the first housing part or the second housing part.

[0013] The first housing part is preferably configured to be separated from the second housing part, and / or preferably spaced apart from the second housing part. The first area of ​​the encapsulation plate can constitute the first lamp chamber of the vehicle lighting device together with the first housing part and the first connecting section, and the first lamp chamber can be closed outwardly by the encapsulation plate. Similarly and separately therefrom, the second area of ​​the encapsulation plate can constitute the second lamp chamber of the vehicle lighting device together with the second housing part and the second connecting section. Preferably, the first lamp chamber is configured to be separated from the second lamp chamber and / or larger than the second lamp chamber. Instead of the second lamp chamber, a partial housing of one or more environmental sensors for a motor vehicle can be constituted by the second area, the second housing part and the second connecting section in a corresponding manner and type. The first housing part and the second housing part can be fixedly connected to each other only via the encapsulation plate device, in particular via the encapsulation plate. That is to say, if the encapsulation plate device breaks at a set breaking position, the first housing part can be decoupled from the second housing part.

[0014] Preferably, the support structure extends from the cover plate on the back side. Adjacent to the above-mentioned boundary between the first and second areas of the cover plate, the first and / or second connecting section can be configured to be essentially L-shaped (when viewed in a cross-sectional plane extending perpendicular to the main surface), preferably the short legs of the first and second connecting sections respectively contact the cover plate (directly or indirectly). These short legs can jointly form a reinforcement layer for the vehicle lighting device. If a set breaking point is (also) configured in the support structure, the set breaking point is preferably located in the reinforcement layer.

[0015] The set breaking point is preferably formed as a material thinning portion or a wall thickness mutation portion in the closure plate and / or in the support structure, especially in the hardening layer. During the manufacture of the closure plate device, by correspondingly contouring the injection mold, such a set breaking point can be manufactured by injection molding in a relatively simple and effective manner. Most preferably, the set breaking point can be formed in the reinforcement layer and / or in the closure plate by means of a cutout portion. In other words, the set breaking point can be formed as a cutout that tapers toward the outer surface of the closure plate opposite to the shell.

[0016] On the outer surface (i.e. the outside / front side), the closure plate (at least at the boundary between the first area and the second area) is preferably configured to be seamless. In particular, the closure plate can have a layer without a joint on the outside, and the layer without a joint constitutes a light plate at least in the first area. Therefore, the internal area can be better protected from environmental influences. In addition, the vehicle lighting device can be better integrated into the vehicle in this way. If the entire closure plate device includes the closure plate and a possible supporting structure or at least the closure plate is made into a casting (so-called multi-component casting), preferably a plastic casting, then the closure plate with these characteristics can be manufactured quickly and cost-effectively. The layer without a joint can be integrally (composed of a first material) here. In addition, the supporting structure can be integrally (composed of a second material). The first material and / or the second material can be a polymer, especially polycarbonate (PC). Alternatively, the first material can be polymethyl methacrylate (PMMA).

[0017] In addition, in order to form the first lamp chamber, it is preferred that the first area of ​​the encapsulation plate is transparent. Accordingly, an illuminating device can be provided in the first lamp chamber so that, for example, a headlight, in particular a headlamp and / or a daytime running light, can be provided in the first lamp chamber. The second area of ​​the encapsulation plate is preferably opaque, opaque or translucent, so that the content of the second inner area can be shielded by the encapsulation plate. In the second inner area, for example, at least one environmental sensor, in particular a radar sensor or a laser radar sensor can be arranged, which cannot be seen from the outside. In order to achieve this concealment, the first and / or second area of ​​the encapsulation plate can be provided with a film (so-called decorative film) that is at least partially opaque or translucent. The film can also be made of a polymer (in particular polycarbonate) to achieve high radar transparency.

[0018] In another variant, the cover plate can have a light guide. In particular, the light guide can be configured as a surface light guide. In addition, it can extend on the first and / or second area of ​​the cover plate. Preferably, the light guide is configured to decouple the light propagated through the light guide so that the light comes out on the light exit surface of the cover plate toward the surrounding environment of the vehicle lighting device. The light guide is preferably configured between the layer without a joint and the housing. If a film is provided, the light guide can preferably be configured on the back side of the film (directly or indirectly) and thus between the film and the housing. Therefore, the film can be illuminated from behind more evenly by means of the light guide. If the film extends on the first and second areas, the light guide can preferably also extend on the first and second areas. And if the film is only configured on the first or second area, the light guide can also preferably only (indirectly) be configured on the first or second area.

[0019] If a supporting structure is present, it can be formed on the back surface of the closure plate. That is to say, if the light guide forms the back surface of the closure plate, the vehicle lighting device can be particularly simple to manufacture when the first and / or second connecting section contacts the light guide on the back side, in particular when it is cast onto the light guide on the back side. This applies accordingly to the above-mentioned film and to the optional additional reflective layer on the side of the light guide facing the housing. The reflective layer can be regarded as part of the light guide; that is to say, what is said above about the light guide can be applied to the reflective layer accordingly. In addition, the light guide can be equipped with a (e.g. light-refracting or light-scattering) coupling-out optical element (e.g. prism) in order to couple out the light as described above. In order to couple the light into the light guide, the vehicle lighting device can have an additional light source. The light source can be arranged in the first and / or second inner region and thus protected from weather influences.

[0020] In these further variants, the predetermined breaking point can be formed adjacent to the boundary in the reinforcement layer, in the light guide (possibly including the reflective layer), in the film and / or in the layer without the joint, in particular as a cutout or other type of material taper or as a recess in at least one of these components. A vehicle lighting device having these features can be manufactured simply and efficiently. Here, the predetermined breaking point can be formed in a drop-molded manner during the injection molding process.

[0021] The motor vehicle proposed here comprises at least one vehicle lighting device as described above. The vehicle lighting device is preferably configured as a headlight. In particular, the vehicle lighting device can be wider than a quarter of the vehicle width, preferably wider than a third of the vehicle width in its installation position (with respect to the longitudinal axis of the vehicle). When viewed from the front, the encapsulation plate can preferably extend substantially (except up to 15%) over half of the vehicle width, preferably extending from the center of the vehicle in the transverse direction of the vehicle to the side wall. The vehicle lighting device is preferably mounted on the motor vehicle so that when viewed from the front, the first area of ​​the encapsulation plate is horizontally located next to the second area of ​​the encapsulation plate. The second area of ​​the encapsulation plate is preferably arranged closer to the longitudinal axis of the vehicle than the first area.

[0022] The manufacturing method proposed here is used to manufacture the above-mentioned vehicle lighting device and includes an injection molding process, in which the predetermined breaking point is formed in a drop-molding manner. The injection molding process can be a so-called multi-component injection molding process, in which the cover plate can be formed as a first component with a first molding material and the support structure can be formed as a second component with a second molding material injected separately from the first molding material.

[0023] The injection molding process may in particular include the following steps, which are preferably carried out in the order described below: Injecting a first molding material into the cavity of a first injection mold so as to form at least a layer of the cover plate without a joint (as a first component). The layer without a joint can then be provided in the cavity of a second injection mold. A second molding material can be injected into the cavity of a second injection mold, wherein the support structure described in detail above can be formed. After the injection molding process, the housing can be fixed to the support structure with a first housing part and a second housing part.

[0024] In order to manufacture a vehicle lighting device with an opaque or translucent film, the film can be placed as an insert in the cavity of the first injection mold before the first molding material is injected. The layer without the joint is preferably injected directly onto the insert. As an alternative to the layer without the joint or in addition to this, the light guide can be injected on the side of the film opposite to the layer without the joint. The combination of the light guide, the film and the layer without the joint can be particularly advantageously formed by placing the film as an insert in the cavity of the third injection mold, in which the light guide is injected onto the back side of the film. Then, the first mold half of the third injection mold can be replaced with the first mold half of the first injection mold. The first and third injection molds can use the same second mold half, so that the injection molded part (film with light guide) can be left in the second mold half at least partially during the replacement. Thereafter, the injection molded part can therefore be located in the first injection mold, in which the layer without the joint is formed as described above.

[0025] The motor vehicle and the method can have any, in particular all, features of the vehicle lighting system. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Figure 1 Shown for Figure 5 A vehicle lighting device 10 of a motor vehicle 100. Figure 1 In the embodiment, the front side of the vehicle lighting device with the light exiting surface is arranged at the bottom, and the back side is arranged at the bottom. Figure 1 At present, the vehicle lighting device 10 is a headlight of a motor vehicle 100. The vehicle lighting device 10 includes a housing 20 and a cover plate device 30 that closes the housing 20. The housing 20 has a first housing part 22 and a second housing part 24 separated from the first housing part 22.

[0035] like Figure 1As shown, the first housing part 22 and / or the second housing part 24 are designed to be basically half-shell-shaped and open toward the closure plate 32 of the closure plate device 30. Due to this shape, the first housing part 22 determines a first inner area 40 covered by the first area 34 of the closure plate 32, and the second housing part 24 determines a second inner area 42 covered by the second area 36 of the closure plate 32. Along the front edge of the first and second housing parts 22, 24 facing the closure plate 32, a groove 23, 25 respectively extends, and the first and second housing parts 22, 24 are respectively fixedly connected to the closure plate device 30 by means of the groove. The first housing part 22 and the second housing part 24 are spaced apart from each other and are preferably fixedly connected to each other only via the closure plate device 30-most preferably only via the closure plate 32, especially non-destructively and non-detachably connected.

[0036] The closure plate device 30 is designed as a plastic casting, in particular as a multi-component injection-molded part. Such an injection (molded) part may include an integral closure plate 32 and a support structure 52 between the shell 20 and the closure plate 32 as components. Therefore, the support structure 52 is injection-molded onto the closure plate 32 on its front side. The support structure 52 can also be engaged with the grooves 23, 25 on the back side, in particular, it is connected to the shell 20 in a material-locked manner. The closure plate 32 has a first area 34 and a second area 36 that are at least partially transparent. A set breaking point 50 is formed on the boundary between the first area 34 of the closure plate 32 and the second area 36 of the closure plate 32 as part of the closure plate device 30. In particular, the support structure 52 currently includes a reinforcement layer 51, which is partially formed on the first area 34 and partially (on the back side; that is, on the back side) on the first area 34 of the closure plate 32. Figure 1 The reinforcing layer 51 is formed in the second region 36. In the reinforcing layer 51, the break location 50 is configured as a material taper (a cutout on the back side of the closure plate 32). The break location 50 is preferably configured as a cutout that tapers toward the outer surface 64 of the closure plate 32 opposite to the housing 20.

[0037] like Figure 1 As shown, in the lateral direction (parallel to the main surface of the closure plate 32), the set breaking point 50 is located at the boundary between the first area 34 and the second area 36. Optionally, the set breaking point 50 / cut-out portion can extend into the closure plate 32. That is, the set breaking point 50 can be at least partially (also) formed in the closure plate 32. Although the support structure 52 is cut out, the closure plate 32 can be at least on the outside (in the Figure 1 The middle and lower parts) form a layer 58 without a joint area. Figure 1It is also shown that the outer surface 64 of the cover plate 32 opposite the housing 20 is designed to be seamless, especially in the region of the boundary. The outer surface 64 is preferably completely seamless. The layer 58 without joints preferably forms a light panel at least in the first region 34, optionally also in the second region 36. Advantageously, the vehicle lighting device 10 can thus be relatively easily integrated on the vehicle exterior.

[0038] The support structure 52 comprises a plurality of connection sections, by means of which the housing 20 is (preferably only) coupled to the closure plate 32. A first connection section 54 extends from a first region 34 of the closure plate 32 to the first housing part 22 and transversely to the closure plate 32. A second connection section 56, which is separate from the first connection section 54, extends from a second region 36 of the closure plate 32 to the second housing part 24 and transversely to the closure plate 32. The first and second connection sections 54, 56 extend substantially parallel to one another and are formed monolithically ("by one casting", without joints) with the reinforcement layer 51.

[0039] With regard to the optical properties of the closure plate device 30, the closure plate 32 is characterized by transparency in the first area 34. Therefore, the lamp chamber having a first inner area 40 defined by the first housing part 22, the first connecting section 54 and the first area 34 of the closure plate 32 is suitable for forming a headlight. Light functions can be realized in this lamp chamber, for example as a headlight, a daytime running light and / or a signal light. Accordingly, the headlight can have one or more light sources that are not shown separately in the figure. The second chamber having a second inner area 36 defined by the second housing part 24, the second connecting section 56 and the second area 36 of the closure plate 32 can be smaller than the above-mentioned lamp chamber and / or can also be configured as a lamp chamber to form (another) headlight. A headlight, a daytime running light and / or a signal light (and at least one corresponding light source) can also be provided in this other lamp chamber. And in Figure 1 In the variant scheme in, the second area 36 of the closure plate 32 is opaque, opaque or translucent, so that the content of the second inner area is blocked. A motor vehicle surrounding environment sensor, in particular a radar sensor, which is not shown, can be advantageously arranged in the second inner area 42. For the above purpose, the second area 36 of the closure plate 32 has a partially or completely opaque or translucent film 60, which here extends from the reinforcement layer 51 to the side edge of the closure plate 32 for example. The film 60 is not formed in the first area 34 of the closure plate 32, so that better light transmission can be achieved.

[0040] The vehicle lighting device 10 is Figure 2 Another variant shown in Figure 1The difference between the vehicle lighting device 10 in the figure is that a light guide 62 (here a surface light guide) is formed on the side of the film 60 opposite to the outer surface 64 in order to illuminate the second area 36 from the back. The film 60 here is preferably at least partially translucent. The light guide 62 can extend from the side connecting section to the second connecting section 56. The light guide 62 is configured to couple out the light propagated through the light guide 62 so that the light comes out on the light exit surface of the cover plate 32 toward the surrounding environment U of the vehicle lighting device 10. For this purpose, the light guide 62 can have corresponding coupling-out optical devices. A light source can be provided in the second inner area 42 to couple light into the light guide. In addition, Figure 2 The vehicle lighting device 10 has Figure 1 All features of the vehicle lighting device 10 in.

[0041] Figure 3 Another vehicle lighting device 10 is shown with Figure 2 The difference between the vehicle lighting device 10 in FIG. 1 and FIG. 2 is that the film 60 and the light guide 62 are formed not only in the second area 36 of the cover plate 32 but also in the first area 34. Figure 2 In the variant of FIG. 5 , the cover plate 32 is formed in one piece. The film 60 and the light guide 62 are layers that have no joints themselves and form a multilayer cover plate 32. These layers are arranged on the back side of the layer 58 without joints. The support structure 52 contacts the light guide 62 on the inner side / back side at the set breaking point 50. Figure 4 Another vehicle lighting device 10 is shown. Figure 3 The difference between the vehicle lighting device 10 in FIG. 1 and FIG. 2 is that the former has an additional reflective layer 66 (reflective film) on the back side of the light guide 62 . In addition, Figure 3 and Figure 4 The vehicle lighting device 10 has Figure 2 All features of the vehicle lighting device 10 in.

[0042] exist Figure 5 The motor vehicle 100 shown in the figure as seen from the front comprises, for example, two side panels arranged next to each other (in particular at the front end of the vehicle, below the front hood) according to Figures 1 to 4One of the vehicle lighting devices 10. Therefore, the vehicle lighting device 10 is used as a headlight. The two vehicle lighting devices 10 are arranged in a mirror image relative to each other (relative to the longitudinal axis of the vehicle of the motor vehicle 100), so that the first area 34 of the cover plate 32 is farther away from the longitudinal axis of the vehicle than the second area 36 of the cover plate 32. Therefore, the first area 34 preferably forms a light plate, through which light can pass from the light chamber defined thereby into the surrounding environment U. At least one sensor of the motor vehicle 100 can be positioned behind the second area 36. The at least one sensor can be respectively matched with at least one auxiliary system of the motor vehicle 100, so as to provide the auxiliary system with surrounding environment information, for example. Alternatively or additionally to this, another light exit surface can be formed in the second area to further improve the visibility of the motor vehicle.

[0043] exist Figure 6 The method 200 shown in a highly simplified form is for manufacturing Figure 3 , but can also be used accordingly to produce one of the other vehicle lighting devices 10 described herein. The method 200 comprises an injection molding process with steps 202 to 208 and a fixing step 210 by which the housing 20 is fixed to the support structure 52. In a first step 202, a film 60 is provided as an insert in a third injection mold 230 and the third injection mold 230 is closed. Then, in step 204, a molding compound forming the light guide 62 is injected into the cavity of the third injection mold 230 (see Figure 7a ). In the subsequent step 206, the first mold half 232 of the third injection mold 230 is replaced by the first mold half 242, and the film 60 together with the light guide 62 injected thereon remains in the second mold half 234. The first mold half 242 and the second mold half 234 together form the first injection mold 211. Then, in step 206, the first molding material is injected into the cavity of the first injection mold 211 to form at least the layer 58 without the joint of the cover plate 32 (see Figure 7b ). The layer 58 without the joint is then provided in the cavity of the second injection mold 220. In a subsequent step 208, the second molding material can be injected into the cavity of the second injection mold 220, wherein the support structure 52 including the set breaking point 50 can be formed ("drop molded") (see Figure 7c ). After the injection molding process, the housing 20 can be fixed, in particular adhesively bonded, to a support structure in step 210 using the first housing part 22 and the second housing part 24 ( Figure 7d ).

[0044] The terms "comprising", "having", "with", etc. used in the present disclosure should be understood as non-exhaustive. In particular, the term "comprising one / an" in this context means "comprising at least one", i.e. "comprising one / an" does not exclude the presence of other corresponding elements. The terms "first", "second", etc. are only used for enumeration and are not important for the possible order. The term "substantially" is to be understood as within the range of common manufacturing tolerances (+ / -10% of the corresponding value).
