Description

Technical Field

[0001] The invention relates to an aerodynamic system for a vehicle and a vehicle comprising such an aerodynamic system. Background Art

[0002] In the construction of vehicles, restrictions imposed by legal regulations and practical needs of drivers often compete with the desired compactness and / or desired aerodynamics of the vehicle. Typical requirements include exterior lighting of the vehicle, such as brake lights, indicator lights, headlights, fog lights, reverse lights, rear fog lights, etc., and a sufficiently large forward and potentially rearward field of vision for the driver, which is usually limited by the vehicle structure.

[0003] What is needed is an improved technique that alleviates or avoids the above-mentioned problems. Summary of the invention

[0004] This problem is solved by the following technical solution of the present invention.

[0005] According to a first aspect, an aerodynamic system for a vehicle is provided. The aerodynamic system comprises an aerodynamic component configured to be movable relative to the body of the vehicle between a retracted position of the aerodynamic system and at least one extended position when the aerodynamic system is mounted on the vehicle. The aerodynamic system further comprises at least one lighting device for the vehicle, the at least one lighting device being arranged on the aerodynamic component, wherein the at least one lighting device is integrated in a housing of the aerodynamic component and the housing of the aerodynamic component doubles as a housing for the at least one lighting device, in particular wherein the housing constitutes both the housing of the aerodynamic component and the housing of the at least one lighting device. The aerodynamic system further comprises a variable supply line for the at least one lighting device, the variable supply line being adapted to transmit an operating supply provided by at least one supply source of the vehicle to the at least one lighting device, wherein the variable supply line is variable at least according to the range of movement of the aerodynamic component between the retracted position and the at least one extended position. The at least one lighting device is arranged to be visible from the outside of the vehicle when the aerodynamic system is in the retracted position.

[0006] The variable supply line can comprise a supply cable.The variable supply line can comprise one or more electrical sliding contacts.

[0007] The at least one lighting device may be visible from outside the vehicle when the aerodynamic system is in any position, such as in the extended position and / or any other intermediate position.

[0008] The aerodynamic system enables the aerodynamic characteristics of the vehicle to be changed by moving the aerodynamic component in translation. In this way, one or more driving characteristics of the vehicle, such as drag, downforce, etc., can be changed. Changing the aerodynamic characteristics of the vehicle can be advantageous, in particular to make changes according to the driving situation, driving mode, the driving ability of the driver and / or the personal preferences and comfort of the driver. In addition, at least one lighting device for the vehicle arranged on the aerodynamic component is provided, so that the external lighting of the vehicle can be arranged compactly, in particular at least one lighting device does not extend further into the driver's field of vision and / or does not require additional space in the vehicle body. The improved compactness and increased potential shape range of the aerodynamic component and / or the at least one lighting device are further promoted by the housing of the aerodynamic component, which doubles as a housing for the at least one lighting device. That is, at least one lighting device is integrated in the housing without the need for an additional dedicated housing to arrange the various components of the lighting device. The above functions are further promoted by providing a variable supply line. In the case where the aerodynamic component is movable in translation, a variable supply line can be realized, which exhibits favorable reliability and durability. This further enables the use of supply lines for safety-relevant vehicle lights, such as brake lights, in accordance with the usual legal requirements regarding their reliability.

[0009] The term “aerodynamic component” may refer to any part of a vehicle that is translationally movable relative to the body of the vehicle and affects the aerodynamic properties of the vehicle, wherein moving the aerodynamic component changes the effect of the aerodynamic component on the aerodynamic properties of the vehicle.

[0010] The housing can include a plurality of support profiles on the inner surface, which are suitable for individually accommodating each of a plurality of lighting device components of at least one lighting device. In this way, an additional dedicated housing for arranging the various components of the lighting device is omitted, and a stable positioning of the various components of the lighting device can be achieved.

[0011] The aerodynamic component can be an active aerodynamic component that is automatically movable between a retracted position and at least one extended position.

[0012] The aerodynamic component can include at least one of a movable rear Gurney flap or a movable rear spoiler.

[0013] The at least one lighting device can include at least one brake light for the vehicle.

[0014] When the aerodynamic component comprises a movable rear gurney flap or a movable rear spoiler, and the at least one lighting device comprises a brake light integrated in the movable rear gurney flap or the movable rear spoiler, the at least one lighting device can be implemented as a center high-mount stop light (CHMSL) constituting the vehicle. By integrating the CHMSL in the movable rear gurney flap or the movable rear spoiler, a compact arrangement of both the movable rear gurney flap or the movable rear spoiler and the CHMSL can be achieved. In this way, no additional space is required in the vehicle structure for accommodating the CHMSL. In addition, the rearward field of view of the driver does not need to be reduced due to the provision of the CHMSL.

[0015] The aerodynamic component can be adapted to move translationally parallel to a translation direction of the aerodynamic system when the aerodynamic component moves between the retracted position and at least one extended position. The translation direction can be straight or curved. Furthermore, the aerodynamic component can be adapted to move non-rotationally.

[0016] The term "no rotation" may mean the absence of a rotational movement of the aerodynamic component, unless such a rotational movement is (essentially) caused by a translational movement of the aerodynamic component, i.e. parallel to the direction of translation of the curvature, e.g. a translational movement supported by one or more curved guides of the aerodynamic system. The term "no rotation" may particularly mean the absence of structural measures such as rotary bearings and / or rotary actuation measures of the aerodynamic system, which enable the aerodynamic component or parts thereof to rotate about an inner axis of the aerodynamic component and / or to rotate independently of the translational movement.

[0017] Moving the aerodynamic component non-rotatably and parallel to a straight translational direction helps to maintain the orientation of at least one lighting device when the aerodynamic component is moved. This enables use with safety-related lighting devices for the vehicle (such as brake lights, fog lights, etc.), which in different jurisdictions need to comply with a predefined orientation range, a predefined emission angle range and / or a predefined spatial intensity distribution. Furthermore, moving the aerodynamic component non-rotatably facilitates a reliable and durable implementation of a variable supply line, in particular, because twisting of the variable supply line associated with moving the aerodynamic component can be reduced or completely avoided. This further facilitates use with one or more safety-related lighting devices for the vehicle.

[0018] The variable supply line can extend at least partially in the aerodynamic component.

[0019] The variable supply line can include at least one supply cable and a cable retraction device configured to facilitate variable extension of the at least one supply cable according to a range of movement of the aerodynamic component.

[0020] The cable retracting device can comprise at least one elastic element, in particular at least one spring, which acts on the at least one supply cable and / or is integral with the at least one supply cable.

[0021] At least one supply cable may include a helical segment, wherein the cable retraction device includes at least one of: an elastic covering of the supply cable in the helical segment; a helical spring attached to the supply cable and arranged parallel to the helical segment; and / or a supply transmission element of the supply cable, wherein the supply transmission element is selected to exhibit an elastic modulus suitable for making the supply cable elastically extendable according to the range of movement of the aerodynamic component.

[0022] The cable retracting device can comprise a wind-up spring adapted to resiliently wind up at least a portion of the supply cable, or to unwind at least a portion of the supply cable.

[0023] The cable retraction device can also include at least one guide structure configured to guide movement of the at least one supply cable when the aerodynamic component moves between the retracted position and the at least one extended position.

[0024] The at least one lighting device can comprise at least one electroluminescent element. In this case, the variable supply line can comprise at least one cable adapted to transmit an electric current provided by a source of electrical energy of the vehicle to the at least one electroluminescent element.

[0025] Additionally or alternatively, the at least one lighting device can comprise at least one light deflecting element.Furthermore, the variable supply line can comprise at least one optical cable adapted to guide light provided by at least one light source of the vehicle to the at least one light deflecting element.

[0026] According to another aspect, an aerodynamic system for a vehicle is provided. The aerodynamic system comprises an aerodynamic component that is translationally movable relative to a body of the vehicle, parallel to a translation direction of the aerodynamic system; at least one lighting device for the vehicle, the at least one lighting device being arranged on the aerodynamic component; and a variable supply line for the at least one lighting device. The variable supply line is adapted to transmit an operating supply provided by at least one supply source of the vehicle to the at least one lighting device. The variable supply line is variable depending on a translation position of the aerodynamic component relative to the translation direction.

[0027] According to another aspect, a vehicle is provided. The vehicle includes the aerodynamic system provided herein. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Further details, objects and advantages of the present invention will become apparent from the accompanying drawings and the following detailed description.

[0034] Figure 1 An aerodynamic system 100 for a vehicle is schematically and exemplarily shown. The aerodynamic system 100 includes an aerodynamic component 110. Figure 1 As shown by the single arrow in , the aerodynamic component 110 is adapted to move in a translational manner relative to the body of the vehicle on which the aerodynamic system 100 is installed, parallel to the translational direction T of the aerodynamic system 100. In addition, as Figure 1 As indicated by the double arrow in , the aerodynamic component 110 is adapted to move reversibly, ie in two directions parallel to the translation direction T.

[0035] The aerodynamic system 100 further includes a lighting device 120 disposed on the aerodynamic component 110. The lighting device 120 is configured to serve as a lighting device for a vehicle on which the aerodynamic system 100 is mounted.

[0036] The aerodynamic system 100 also includes a variable supply line 140 for the lighting device 120. The variable supply line 140 is configured to transmit an operating supply provided by a supply source of the vehicle (eg, a battery or a light source) to the lighting device 120. Figure 1 As indicated by the double arrow adjacent to the variable supply line 140 , the variable supply line 140 is adapted to vary according to the movement of the aerodynamic component 110 .

[0037] In the illustrated example, the aerodynamic system 100 further includes a support structure 150 that supports and at least partially houses the aerodynamic component 110 and the variable supply line 140. The support structure 150 is also adapted to facilitate mounting of the aerodynamic system 100 in a vehicle structure.

[0038] In the example shown, the translation direction T is a straight direction. In other examples, the translation direction T is a curved direction, for example, according to a curved shape of the aerodynamic component 110 and / or according to one or more curved guides of the support structure 150 that guide the movement of the aerodynamic component 110.

[0039] In the example shown, the aerodynamic component 110 is a rear Gurney flap. Additionally, in this example, the lighting device 120 is a center high mounted stop light CHMSL for the vehicle. However, it should be understood that in other examples, the features and advantages of the aerodynamic system 100 described herein can be implemented and achieved accordingly, for example, in combination with other types of aerodynamic components and / or other types of vehicle lights.

[0040] In some examples, the lighting device 120 includes an electroluminescent element, such as a light emitting diode (LED) or a light bulb. In such examples, the variable supply line 140 includes one or more cables adapted to transmit current between a source of electrical energy of the vehicle (such as a battery) and the electroluminescent element. In other examples, the lighting device 120 includes at least one light deflecting element, such as a reflector or a light guide, and the variable supply line 140 is adapted to direct light that has been generated by a light source external to the aerodynamic system 100 to the lighting device 120.

[0041] The lighting device 120 is integrated into the aerodynamic component 110 , in particular into the housing 112 of the aerodynamic component 110 .

[0042] The aerodynamic component 110 is adapted to be reversibly movable parallel to the translation direction T of the aerodynamic system 100. In some examples, the aerodynamic component 110 is manually extendable in the translation direction T and manually retractable against the translation direction between a retracted position and at least one extended position of the aerodynamic component 110. In other examples, the aerodynamic component 110 is an active aerodynamic component that is automatically movable parallel to the translation direction T in a reversible manner, for example, by means of one or more actuators (not shown) of the aerodynamic system 100.

[0043] In some examples, the aerodynamic component 110 can be moved between the retracted position and each of the plurality of extended positions. In some examples, the plurality of extended positions include two or more discrete extended positions, and the aerodynamic component 110 can be moved between the two or more discrete extended positions gradually or in other words in a stepwise manner. In some examples, the plurality of extended positions include a continuous extended position, and the aerodynamic component 110 can be moved between the continuous extended positions in a continuous or in other words non-stepless manner.

[0044] like Figure 1 Schematically indicated, the lighting device 120 is arranged to be visible from outside the vehicle even when the aerodynamic system 100 is in the retracted position. This facilitates the use of the lighting device 120 as a safety-related light, for example as a brake light, since the lighting device 120 is independent of the position of the aerodynamic system 100 and is visible to other traffic participants.

[0045] As combined Figure 2 In a more detailed description, the housing 112 of the aerodynamic component 110 doubles as a housing for at least one lighting device 120. In other words, the housing 112 constitutes both the housing of the aerodynamic component 110 and the housing of at least one lighting device 120. This enables a compact implementation and expands the range of possible shapes of the aerodynamic system 100, enhancing the usability of various vehicle designs.

[0046] exist Figure 1 In the example of the embodiment of the invention, the movement of the aerodynamic component 110 is limited to a translational movement parallel to the translational direction T, i.e. to a movement without rotation. Limiting the movement of the aerodynamic component 110 to a translational movement parallel to the predetermined direction facilitates a reliable and durable implementation of the variable supply line 140. It also facilitates the use of the aerodynamic system 100 in combination with safety-related lighting for the vehicle via the lighting device 120. In particular, when the aerodynamic component 110 is moved without rotation with a translational movement parallel to the linear translational direction T, the orientation of the lighting device 120 can remain constant.

[0047] However, in other examples, the aerodynamic component 110 can be adapted to perform a rotation simultaneously with or separately from the translational movement. In particular, in the case where the aerodynamic component 110 is a rear spoiler (rather than a Figure 1In an embodiment of the aerodynamic system 100 with a rear Gurney flap (shown in FIG. 1 ), a variable tilt of the rear spoiler can be generated according to the translational position of the rear spoiler parallel to the translational direction T. To this end, in some examples, the automatic rotational movement is superimposed on the translational movement of the rear spoiler. However, even when the aerodynamic component 110 is implemented as a front spoiler or a rear spoiler, in some examples, the aerodynamic component 110 is still limited to a translational movement parallel to the translational direction of the aerodynamic system 100, wherein the translational direction is straight or curved. In addition, when the aerodynamic component 110 is a front spoiler, in some examples, the at least one lighting device 120 includes one or more fog lights of the vehicle.

[0048] Figure 2 The aerodynamic system 200 is schematically and exemplarily shown. The aerodynamic system 200 represents Figure 1 Some examples of aerodynamic systems 100 are shown.

[0049] The aerodynamic system 200 comprises an aerodynamic component 210 in the form of a rear Gurney flap. The aerodynamic component 210 is adapted to be reversibly movable parallel to the translation direction T of the aerodynamic system 200. In a housing 212 of the aerodynamic component 210, a lighting device 220 is arranged. The aerodynamic system 200 further comprises a variable supply line 240, which is adapted to transmit an operating supply from an external supply source to the lighting device 220. With regard to these features of the aerodynamic system 200, the description of the aerodynamic component 110, the lighting device 120, the variable supply line 140 and the housing 212 of the aerodynamic system 100 applies accordingly, unless clearly different from the drawings and the following description.

[0050] In the aerodynamic system 200, the lighting device 220 includes an electroluminescent element 222, such as a light emitting diode or a light bulb. In the example shown, the light emitting element 222 is arranged on a printed circuit board 224. In addition, a variable supply line 240 extends partially within the aerodynamic component 210 and contacts the printed circuit board 224. In this example, the variable supply line 240 includes at least one cable that is suitable for transmitting current between the electrical energy source of the vehicle and the electroluminescent element 222.

[0051] The aerodynamic system 200 also includes a plurality of optical components arranged to deflect the light generated by the light emitting element 222. In the illustrated example, the optical components of the lighting device 220 include a thin thick-walled optical element 226, a diffuser 228, and an outer lens 230 on which the diffuser 228 is mounted and which is flush with the outer contour of the housing 212.

[0052] like Figure 2As schematically shown, the housing 212 includes a plurality of support profiles on its inner surface, which independently accommodate each of the various components 222, 226, 230 of the lighting device 220. In this way, the housing 212 doubles as a housing for the lighting device 220, making it possible to omit an additional dedicated housing for arranging the various components of the lighting device 220. At the same time, reliable positioning of the components 222, 226, 230 is achieved.

[0053] In the aerodynamic system 200, as described above, the lighting device 220 includes a light emitting element 222. In other examples, the light emitting element is external to the aerodynamic system, for example, arranged in the body of the vehicle. In these examples, the variable supply line is configured to transmit light that has been generated by the external light emitting element to the lighting device of the aerodynamic system 200, in particular to an optical component that deflects light that has been outcoupled from the variable supply line 240 at the lighting device 220.

[0054] Figure 3 A variable supply line 300 for use in an aerodynamic system as described herein is schematically and exemplarily shown. The variable supply line 300 includes one or more supply cables 310. The variable supply line 300 also includes a cable retraction device 320. The cable retraction device 320 is configured to facilitate variable extension of the supply cable 310 parallel to the translation direction T of the aerodynamic system in which the variable supply line 300 is used. In the illustrated example, the variable supply line 300 also includes a guide structure 330, which is exemplarily shown as a tubular structure, in which the supply cable 310 is at least partially arranged. The variable supply line 300 is configured to provide an operational connection between a lighting device arranged on an aerodynamic component of the aerodynamic system and a supply source arranged in the body of the vehicle. For this purpose, the variable supply line 300 is also configured to provide a variable mechanical connection between a movable aerodynamic component of the aerodynamic system and the body of the vehicle.

[0055] In the illustrated example, the cable retraction device 320 includes an elastic coating 322 of the supply cable 310 in combination with the helical supply cable 310. The cable retraction device 320 also includes a helical spring 324 attached to the helical section of the supply cable 310. The elastic coating 322 and the helical spring 324 each facilitate elastic and reversible extension of the supply cable 310 parallel to the translation direction T.

[0056] In other examples of the variable supply line 300, the cable retraction device includes other and / or additional retraction measures. In some examples, the helical segment of the supply cable 310 includes a supply transmission element (such as a wire) that has been selected to exhibit an elastic modulus suitable for elastically extending the supply cable 310 parallel to the helical axis as required in accordance with the translational movement of the aerodynamic component. For example, each of the material, thickness, and helical shape of the supply transmission element (such as a metal wire) has been selected to produce the desired elastic modulus in combination in the translation direction T. In some of these examples, the elastic coating of the supply cable 310 is omitted.

[0057] In other examples, the cable retracting device 320 additionally or alternatively includes a winding spring (not shown) that acts on the coil to at least partially automatically wind up the supply cable 310 and / or unwind the supply cable 310 .

[0058] In some examples, at least a portion of the cable retraction device 320 is configured to be fixedly connected to the body of the vehicle. Furthermore, in some examples, additionally or alternatively, at least a portion of the cable retraction device 320 is configured to be fixedly connected to the aerodynamic component. In other examples, the cable retraction device 320 is not fixedly connected to either the body of the vehicle or the aerodynamic component.

[0059] The guide structure 330 is used to guide the movement of the supply cable 310, in particular the movement parallel to the translation direction T. Alternatively, in some examples, for example, if the supply cable 310 and / or the cable retraction device 320 provide sufficient stability to substantially limit the movement of the cable 310 to the movement parallel to the translation direction T, the guide structure 330 can be omitted.

[0060] exist Figure 3 In the example shown, the translation direction T is a straight direction. However, the above description is similarly applicable to other examples in which the translation direction T is curved.

[0061] In addition, the variable supply line 300 shown is configured to provide an operating supply based on the non-rotational movement of the aerodynamic component using a flexible supply cable 310. In other examples, the operating power supply is provided via the variable supply line 300 using one or more electrical sliding contacts. In addition, or as an alternative, in some examples, the variable supply line 300 also provides an operating supply related to the rotational movement of the aerodynamic component. In some of these examples, the variable supply line 300 also additionally includes one or more rotating electrical sliding contacts for this purpose.

[0063] The electroluminescent element 422 of the lighting device 420 is arranged at the body-side end of the aerodynamic component 410. The electrical contacts of the light-emitting element 422 extend through the housing 412 of the aerodynamic component 410. Thus, the variable supply line 440 extends substantially outside the aerodynamic component 410. Furthermore, the aerodynamic system 400 comprises a plurality of optical components for transmitting and deflecting the light that has been generated by means of the light-emitting element 422 through the aerodynamic component 410 inside the housing 412. Figure 4 Schematically shown, the optical components include a collimator 424, a reflector 426, and a diffuser 428. However, other examples of aerodynamic system 400 include additional and / or other optical components for directing light within housing 412.

Light guide 722 is configured to guide light that has been received from a light emitting element and, as desired, outcouple the received light at a suitable location on the surface of light guide 722. In some examples, the light emitting element resides in aerodynamic component 410. In other examples, the light emitting element resides outside aerodynamic component 410, located in the body of the vehicle. When the light emitting element resides outside aerodynamic component 410, variable supply line 440 includes a variable light guide that operably connects light guide 722 and the light emitting element.
