The present disclosure relates to tailgates and, specifically, to lighting systems of tailgates of a vehicle having plastic glazing.
Vehicles such as sports utility vehicles (“SUVs”), vans, hatchbacks, and the like include a structural component known as a tailgate. The tailgate is provided to open or close an opening formed at a rear portion of a vehicle. The tailgate is typically hinged to the main vehicle body, for example, along its upper end, such that it can swing open and close. Examples of tailgates include a rear door tailgate or a truck lid tailgate.
The tailgate may support one or more other vehicle components, such as a rear window and one or more light assemblies (e.g., a supplemental brake light, a puddle light). The tailgate may also be adjacent to body cavities into which rear lamp units are inserted. These parts and other parts may add to the cost and complexity of assembling a vehicle.
Light assemblies in vehicles, in particular, comprise a large number of separate components. For example, a typical vehicle may have several different types of lights, including, for example, parking lights, turn indicator lights, brake lights, and the like. Each of these lights may be made from many parts. These parts add to the cost and complexity of assembling a vehicle. Accordingly, as recognized in U.S. Pat. No. 7,048,423 (“the '423 Patent”), it desirable to have a lighting assembly with fewer parts. The '423 Patent discloses an integrated light assembly including a plurality of lamps 210, 216 enclosed in a housing 202, which may serve as a lens for the lamps, and mounted on a substrate 204. Because the lamps 210, 216 share a common substrate and lens, the additional cost of having a separate lamp unit is eliminated. This structure disclosed in the '423 Patent, however, has many drawbacks. For one, because multiple lamps are mounted together in a single housing without sidewalls or reflectors for directing the angle of their light, the structure does not account for haziness issues. Moreover, if two lights of varying color are mounted in the housing, the structure disclosed in the '423 Patent does not have a way of preventing color overlap. These drawbacks may limit the use of such a light assembly in a vehicle under state and federal regulations governing vehicle lighting requirements. Thus, while the '423 Patent discloses an integrated part for a vehicle, its application may be limited.
Moreover, conventional light assemblies in vehicles, including the one described in the '423 Patent, remain separate from other vehicle components. In particular, a light assembly may have a lens portion and a housing portion that are separate from the remaining components of a vehicle. Thus, while a light assembly may be placed behind a translucent component of a vehicle, such as, for example, a glass exterior, the light assembly may have a separate lens for transmitting a light to an exterior of the vehicle. And while a light assembly may be supported in place in a vehicle by another vehicle component, the light assembly may have a separate housing unit for supporting its light source. Such portions of a light assembly may add to the overall weight of a vehicle, and the overall complexity and cost of manufacturing and assembling a vehicle.
Inhomogeneities such as seams and openings between separate vehicle components may also add to the cost of assembling, sealing and/or insulating an interior of the vehicle and/or its components. Moreover such seams and openings may cause aerodynamic inefficiencies and disturb the vehicle's overall aesthetical appearance. Additional components may also be required to connect separate vehicle components to one another, which may add to the overall weight of a vehicle.
The present disclosure aims to solve these problems and other problems in the prior art.
In accordance with the purpose(s) of the invention, as embodied and broadly described herein, this disclosure, in one aspect, relates to vehicle components, including tailgates, and to lighting systems of tailgates with plastic glazing.
As will be apparent from the present disclosure, problems and/or objectives for improvement with respect to a tailgate including plastic glazing, as described herein, may include providing a tailgate that integrates one or more other components of a vehicle, thereby reducing a total number of components of a vehicle and reducing the complexity and cost of assembling a vehicle. Such problems and/or objectives for improvement also may include providing a tailgate that reduces a number of inhomogeneities, seams, and other faults along a surface of a vehicle, thereby increasing an aesthetic appearance of the vehicle and increasing aerodynamic performance. Such problems and/or objectives for improvement further may include providing a tailgate that conceals one or more other features of a vehicle, such as, for example, a light assembly or unit, thereby increasing an aesthetic appearance of the vehicle.
Problems and/or objectives for improvement with respect to a tailgate, as described herein, may also include providing a tailgate with integrated lighting functions. For example, the present disclosure may provide a tailgate having a plastic glazing that functions as a lens of a molded light assembly. The molded light assembly may be, for example, a tail lamp, a turn signal light, a puddle light, a license plate light, or an interior light. A housing unit connected to the back of the plastic glazing may support and isolate the molded light assemblies from one another, thereby preventing any color overlap between the various light assemblies. The housing unit may also remove the need for a separate housing unit for each molded light assembly. As such, the housing unit and the plastic glazing of the tailgate may reduce a number of components required to assemble the lighting system of a vehicle. The plastic glazing may also be made using an automated, machine-based, injection molding process, further streamlining production and reducing labor costs.
Problems and/or objectives for improvement with respect to a tailgate, as described herein, may also include replacing certain heavier components of a vehicle with plastic components. For example, the present disclosure may provide a tailgate formed entirely of plastic components, whereby a translucent portion of the tailgate that is transparent may serve as a rear window instead of a glass component. The plastic may weigh less than a glass window, and may also have stronger structural qualities.
Problems and/or objectives for improvement with respect to a tailgate, as described herein, may also include incorporating a texture, marking, or the like into a plastic glazing of a tailgate in order to enhance certain lighting features of the tailgate. The texture, marking, etc. may affect the passage of light through the plastic glazing to serve both a functional and aesthetical purpose. For example, the plastic glazing may comprise a texture along a region that serves as a lens of a molded light assembly to disperse light emitted by the molded light assembly to satisfy regulatory requirements and/or produce a certain aesthetical effect.
Accordingly, aspects of the present disclosure provide plastic glazing of a tailgate of a vehicle, the plastic glazing comprising: a first translucent component; a second translucent component molded onto the first translucent component, wherein the second translucent component comprises a color, wherein the plastic glazing is of one-piece molded plastic construction, wherein an overlapping portion of the first translucent component and the second translucent component forms a lens of a first molded light assembly.
Additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or can be learned by practice of the invention. The advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.
The foregoing summary, as well as the following detailed description, is better understood when read in conjunction with the appended drawings. There is shown in the drawings example embodiments, and the present invention is not intended to be limited to the specific embodiments and methods disclosed.
Aspects of the disclosure will now be described in detail with reference to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views, unless specified otherwise.
Systems and methods disclosed herein provide a tailgate or lift gate and, in particular, a tailgate having a plastic glazing having a one-piece monolithic construction. The one-piece monolithic structure can be fabricated in one piece using an injection molding process. Vehicles of a hatchback or van configuration typically include an access opening at their rear and a tailgate that selectively opens and closes the access opening. The tailgate may be mounted on the main body of the vehicle using a hinged connection. As such, the tailgate may operate like a hinged flap, which swings open and close along the hinged connection. The tailgate is typically operated manually but may also be operated electronically using a power actuator.
The tailgate may support one or more other vehicle components such as a rear glass window, a logo or marking, a light assembly or unit, a license plate holder, etc. These components are usually attached to the tailgate using screws or other connectors or an adhesive. In its closed position, the tailgate may also be adjacent to one or more cavities in the body of the vehicle for receiving a rear lamp unit or other light unit.
In order to reduce the number of separate components of a vehicle, systems and methods disclosed herein may provide an integrated tailgate assembly including and/or integrating one or more other vehicle components. For example, systems and methods disclosed herein may provide a tailgate having a plastic glazing including a rear window. The plastic glazing of the tailgate may be constructed of a thermoplastic polymer including a portion that is clear as the rear window. In other systems and methods disclosed herein, additional vehicle components may also be included in the plastic glazing. Such components may include, for example, a colored translucent portion for a rear light unit; an additional translucent portion for a courtesy light, a license plate light, or other light unit; a cavity and fixation unit (e.g., a threaded hole, a hook or clip) for supporting a light unit; a cavity and fixation unit for supporting a license plate; a textured and/or raised region for a logo or other marking; a spoiler or other aerodynamic feature; an opening that serves as a ventilation opening; and the like.
In particular, systems and methods disclosed herein may also provide an improvement over existing vehicles having separate light units. Light units in many conventional vehicles are typically self-contained and separate from the other components of the vehicle. Each light unit typically requires its own housing unit and lens. Systems and methods disclosed herein provide an improvement over such existing systems by providing a light unit that is integrated with other components of a vehicle. Specifically, systems and methods disclosed herein may provide a plastic glazing of a tailgate that may function as a lens of a light unit. Systems and methods disclosed herein may also provide a housing structure for a tailgate that may function as the housing unit for multiple different light units. Accordingly, systems and methods disclosed herein eliminate the need for having a separate light unit in a vehicle. Such systems and methods allow a light source to be supported within a housing of a tailgate and to use a plastic glazing of the tailgate as its lens. As such, such systems and methods disclosed herein reduce a number of components of a vehicle's light units, thereby reducing a cost of manufacturing and assembling the vehicle.
Systems and methods disclosed herein may provide a tailgate having an integrated lighting system that conforms to certain federal regulatory requirements and/or international standards for vehicle lighting. For example, certain international standards, such as, for example, ECE Regulation No. 48 and SAE Standard J578, may require specific colors of light be emitted from a lighting device for a vehicle. In systems and methods disclosed herein, a light source (e.g., a LED) may be positioned behind a plastic glazing. The color of the plastic glazing may shift the color of the light from the light source. Accordingly, if light sources from existing lighting systems are used, the color of the light emitted from the plastic glazing into the surrounding environment may no longer be in conformance with certain legal requirements. Systems and methods disclosed herein, however, may use light sources having adjusted colors that compensate for the color shift of the plastic glazing. Alternatively, systems and methods disclosed herein may use components for forming a plastic glazing having colors that enable a transmission of light within the legal color space when used with existing light sources. As such, systems and methods disclosed herein provide a method for accounting for a color shift resulting from the use of a colored plastic glazing, such as, for example, a plastic glazing having a green or brown glazing color. A colored plastic glazing may especially be desirable for privacy tinting purposes.
Systems and methods disclosed herein may also provide a tailgate having interior lighting functions. Many individuals desire having interior lighting in a vehicle for both functional and aesthetical purposes. For example, interior lighting may be used to provide a unique ambience within a vehicle. As another example, lights designed to illuminate an interior of the vehicle may serve certain guiding functions. The inclusion of interior lights oftentimes may add to the expense of manufacturing and assembling a vehicle due to the need for additional lighting components. Systems and methods disclosed herein, however, may provide a method for integrating an interior lighting feature into a plastic glazing of a tailgate of a vehicle. The interior lighting feature may be formed as part of an injection molding process for forming the plastic glazing of the tailgate. Accordingly, such systems and methods may reduce a number of additional components needed for the interior lighting feature. Because the injection molding process may be machine-automated, such systems and methods may also automate the process for forming the interior lighting feature.
Systems and methods disclosed herein may also provide a tailgate having applique lighting. The tailgate may have a plastic glazing that is formed with a plurality of depressions, each for receiving a corresponding lens or cover component of the applique lighting. The dimensions of the depressions in the plastic glazing and the dimensions of the cover components may be designed to have an interference fit between them, such as, for example, a 0.1 mm interference fit. The dimension of the thickness or height of the cover may be configured such that the cover, when placed within the depression, forms a surface that is flush with a surrounding region of the plastic glazing. In a preferred embodiment of the present disclosure, the applique lighting may be in the shape of letters or other graphic designs. The height and width of the letters may vary depending on the desired appearance of the applique lighting.
Systems and methods disclosed herein may also provide a tailgate that reduces a number of inhomogeneities, seams, and other disruptions, interruptions, and gaps along a surface of a vehicle, thereby increasing an aesthetic appearance of the vehicle and increasing aerodynamic performance. Systems and methods disclosed herein further may provide a tailgate that conceals one or more other features of a vehicle, such as, for example, a light unit, thereby increasing an aesthetic appearance of the vehicle.
Systems and methods disclosed herein may also provide a method of manufacturing a tailgate or, specifically, a plastic glazing of a tailgate. Such systems and methods may provide a method of producing a plastic glazing using multi-shot injection molding techniques. For example, in certain aspects of the disclosure, a plastic glazing of a tailgate may be formed via a three-shot injection molding process. In a first shot, a clear thermoplastic polymer may be injected to form a shell or outline of the plastic glazing. In a second shot, a colored thermoplastic polymer may be injected to form one or more colored regions in the plastic glazing. For example, a red thermoplastic polymer may be injected to form a red translucent region to serve as the lens for a rear light of a vehicle.

The plastic glazing 100 has a first colored portion 102 that functions as a portion of a right tail lamp of the vehicle, and a second colored portion 104 that functions as a portion of a left tail lamp of the vehicle. In particular, the colored portions 102, 104 can function as lenses of the tail lamps of the vehicle. The plastic glazing 100 also has a third portion 106 for an additional light unit such as, for example, an axillary brake light or a courtesy light. The plastic glazing 100 also includes a clear transparent portion 108 that functions as a rear window of the vehicle, and a colored non-transparent portion 110. The colored non-transparent portion may be strategically placed to hide one or more structures positioned behind the plastic glazing 100.
Referring now to
The light units 202, 204, 206 may be a single type of light unit. For example, the light units 202, 204, 206 can be brake light units. Alternatively, the light units 202, 204, 206 may comprise more than one kind of light unit. For example, the light units 202, 204 can be brake light units, and the light unit 206 can be a courtesy light unit.
The plastic glazing 100 may be secured to the housing unit 200 such that the light units 202, 204, 206 are disposed between the plastic glazing 100 and the housing unit 200. In particular, the plastic glazing 100 may be secured to the housing unit 200 such that the light units 202, 204, 206 are disposed behind the portions 102, 104, 106 (depicted in
Each of the light units 202, 204, 206 may comprise a light source that generates a white or a colored light. The light generated by the light units 202, 204, 206 may pass through the portions 102, 104, 106, respectively.
Light emitted from the light units 202, 204, 206 through the portions 102, 104, 106 of the plastic glazing 100 may be emitted as a colored light in accordance with certain international standards governing vehicle lighting such as, for example, ECE Regulation No. 48 and SAE Standard J578. As noted above, the portions 102, 104 can function as the lens for the vehicle's tail lamps. Accordingly, light emitted from the light units 202, 204 through the portions 102, 104 may be red. ECE Regulation No. 48 defines the color “red” as emitted light with chromaticity coordinates (x,y) that lie within the chromaticity areas defined by the following boundaries in the CIE xyY color space:
R12 yellow boundary: y=0.335
R23 the spectral locus
R34 the purple line
R41 purple boundary: y=0.980−x
With the following (x,y) intersection points:
R1: (0.645, 0.335)
R2: (0.665, 0.335)
R3: (0.735, 0.265)
R4: (0.721, 0.259)
Thus, to fulfill this regulation, the light emitted through the portions 102, 104 may have chromaticity coordinates (x,y) that fall within the chromaticity area defined for the color red in ECE Regulation No. 48, as set forth above.
While the portions 102, 104 and the light units 202, 204 are described herein as producing a red light, one of ordinary skill in the art would appreciate that the portions 102, 104 and the light units 202, 204 may also be designed to produce lights having other colors, such as, for example, yellow or amber. These colors are also defined in ECE Regulation No. 48 as well as in other international standards.
The housing unit 200 also includes an opening 208. When the plastic glazing 100 is secured to the housing unit 200 such that the light units 202, 204, 206 line up with the portions 102, 104, 106, the opening 208 may line up with the clear transparent portion 108 of the plastic glazing 100. By lining up with the clear transparent portion 108, the opening 208 allows an individual's view through the transparent portion 108 (which, as described above, may function as the rear window of the vehicle) to remain unobstructed.
Each of the light units 202, 204, 206 may include one or more light components such as, for example, an incandescent lamp, an electroluminescent lamp, a gas discharge lamp, and the like. Because the light units 202, 204, 206 are secured directly onto the housing unit 200, a separate housing for each light unit 202, 204, 206 may not be needed. Thus, the housing unit 200, which serves as the structural carrier for the plastic glazing 100 of the tailgate, integrates a housing function of a light unit. Moreover, because the portions 102, 104, 106 may function as the lens of a light unit—i.e., the portion 102 may function as the lens for the light unit 202, the portion 104 may function as the lens for the light unit 204, and the portion 106 may function as the lens for the light unit 206—a separate lens for each light units 202, 204, 206 also may not be needed.
The plastic glazing 100 may be secured to the housing unit 200 using an adhesive and/or a mechanical fastening system (e.g., a screw bolt or clip fastening system). The adhesive used may be a commercially available adhesive that is typically used in the automotive industry for the adhesive bonding of plastic components. Such adhesives may include, for example, wet adhesives, contact adhesives, hot-melt adhesives, or reaction adhesives. The thickness of the adhesive required may vary depending on the specific geometries of the plastic glazing 100 and the housing unit 200. When the adhesive is a hot-melt adhesive that can be processed under thermoplastic conditions, it may be possible to bond the plastic glazing 100, the housing unit 200, and the hot-melt adhesive together during a multi-shot injection molding process.
While the tailgate including the plastic glazing 100 and the housing unit 200 is depicted as having three light units 202, 204, 206, one of ordinary skill in the art would appreciate that the tailgate can comprise less or more light units. Such light units may include, for example, license plate lamps, turn signal lamps, backup lamps, and the like.
A light source 308 of the light unit 204 may be disposed behind the colored portion 104. The light source 308 may emit light beams that travel through the colored portion 104 to an exterior of the vehicle. The light source 308 may be supported by a portion 306 of the housing unit 200. The portion 306 may form the cavity 214 for receiving the light unit 204. The light source 308 may be mounted to the housing unit 200 using a fixation mechanism (e.g., a screw system, an adhesive, and the like).
When the light beams emitted by the light source 308 travel through the overlapping portion of the first component 302 and the second component 304 (i.e., the colored portion 104), their color, intensity, and direction of travel can be altered depending on the properties of the first component 302 and the second component 304. Relevant properties may include, for example, the colors of the first component 302 and the second component 304, the thicknesses of the first component 302 and the second component 304, the internal molecular structure of the first component 302 and the second component 304, etc. As such, these properties can be adjusted to achieve a certain desired color of emitted light, at a certain dispersion level and at a certain intensity.
As described above, certain international standards such as ECE Regulation No. 48 and SAE Standard J578 may define certain color requirements for particular types of vehicle lights. For example, the U.S. Department of Transportation requires that vehicle tail lamps emit a red colored light in accordance with SAE Standard J578. SAE Standard J578 defines a red light as a light having a chromaticity value that falls within the color space defined by yellow boundary corresponding to y=0.33 and a purple boundary corresponding to y=0.98−x. ECE Regulation No. 48 sets forth the same standard. The U.S. Department of Transportation also requires that turn signal lights on vehicles emit a red or amber colored light. SAE Standard J578 defines an amber light as a light having a chromaticity value that falls within the color space defined by a red boundary corresponding to y=0.39, a white boundary corresponding to y=0.79−0.67x, and a green boundary corresponding to y=x−0.12.
In a preferred aspect of the disclosure, the colors of the first component 302 and the second component 304 may be selected, taking into account the color of the light emitted by the light source 308, such that the color of the light emitted through the plastic glazing 100 may fall within the color space defined required by federal regulations, as defined by the SAE Standard J578 or another international standard. If the light source 308 emits a white light, then the colors of the first component 302 and the second component 304 may be selected such that they impart a red color to the white light as it passes through the first component 302 and the second component 304. If the light source 308 emits a colored light, then different colors for the first component 302 and the second component 304 may be selected such that the color of the colored light shifts accordingly to meet regulatory requirements when it passes through the first component 302 and the second component 304.
The colors of the first component 302 and the second component 304 may also be adjusted to account for their individual colors. For example, the first component 302 may form a rear window of the vehicle. Thus, it may be desirable to have the first component 302 have a green or brown tint. Such may undesirably shift the color of any light that passes through the first component 302 away from the red or amber color required by federal regulations. Accordingly, in an effort to avoid falling out of the legal color space, the color of the second component 304 can be selected such that it accounts for the undesirable color shift that the first component 302 will produce.
While
The third component 310 may be a non-transparent so that it forms a region of blackout (e.g., opaque or substantially opaque) adjacent to the overlapping portion of the first component 302 and the second component 304 (i.e., the colored portion 104). The third component 310 may be black or be another color and/or effect. This region of blackout may be configured to conceal the sections of the portion 306 of the housing unit 200 that are attached to the plastic glazing 100, and any adhesive or other fixation mechanism used to attach the housing unit 200 to the plastic glazing 100.

Additionally, the plastic glazing 400 may comprise a logo or marking 408. The logo 408 may be raised from a region of the plastic glazing 400 that surround it. The logo 408 may be an example of a raised marking. Further details of the logo 408 are described with reference to
The first component 424 and the second component 422 may be formed of a thermoplastic polymer. The first component 424 and the second component 422 may be formed as part of an injection molding process for forming the plastic glazing 400. In a first shot, a first material may be injected into a mold cavity having a first volume to form the component 420. Then, in later shots, the first component 424 and the second component 422 of the logo 408 may be molded onto the component 420. The first component 424 and the second component 422 may bind to the component 420 through melt bonding. To enable optimal bonding between the separate components, the first component 424 and the second component 422 of the logo 408 as well as the component 420 may be formed of a similar thermoplastic polymer, e.g., different colors of polycarbonate resin.
While the logo 408 is depicted as having a first component 424 and a second component 422 in

Additionally, as depicted in
According to certain aspects of the disclosure, the tailgate assembles disclosed herein may also include additional layers on top of the thermoplastic polymer layers. For example, a layer for increasing scratch resistance may be added to an exterior surface of the plastic glazing. As another example, an additional layer for adding more support to the thermoplastic polymer layers may also be added to an interior surface of the plastic glazing. This additional layer may be formed of a plastic, a metal, or other material for increasing the structural strength of the tailgate.
