Description

[0001] The invention relates to a motor vehicle according to the preamble of claim 1.

[0002] EP 3 636 518 A1 discloses a motor vehicle with a front section comprising side fenders and headlights. A flow channel for air is formed laterally next to each headlight, between the headlight and the fender located next to it. Air can be directed through this flow channel from an area in front of the headlight towards an area behind it.

[0003] DE 10 2017 124 227 A1 discloses a further motor vehicle with a front section that includes side fenders and headlights. Air can be directed past the headlights towards a wheel arch via a flow channel.

[0004] JP 2019-55627A, JP 2003-34271A, and US 2018 / 0051859A1 disclose further motor vehicles. Further motor vehicles are known from DE 102018121002A1 and DE 112016004892T5.

[0005] DE 10 2020 202 681 A1 discloses a one-piece cover for an air duct of a trim component without a see-through effect in the interior area of ​​a motor vehicle.

[0006] DE 10 2008 060 410 A1 and DE 10 2018 109 709 A1 disclose motor vehicles with flow channels and air intake baffles for such flow channels formed in the area of ​​a rear wheel arch.

[0007] If air from an area in front of a headlight can be directed towards an area behind it via a flow channel located laterally next to the headlight, between the headlight itself and the fender positioned next to it, then, depending on the viewer's angle, it may be possible to see into the flow channel. This is aesthetically undesirable. It is therefore necessary to prevent the view into such a flow channel as much as possible and, furthermore, to guide the airflow in the channel's inlet area in an advantageous manner.

[0008] The object of the invention is to create a corresponding motor vehicle.

[0009] This problem is solved by a motor vehicle according to claim 1.

[0010] According to the invention, a baffle is arranged in an inlet opening of the respective flow channel, which allows air to enter the respective flow channel, wherein the respective baffle has a frame-like support part for attaching the respective baffle to the respective fender and a frame-like viewing part mounted on the support part with a circumferential frame and several lamellae extending horizontally between the frame, which form flow-guiding surfaces for the air, wherein the support part has cover areas for covering sections of the fender in order to conceal a direct view into the interior and thus onto sections of the respective flow channel, and wherein the viewing part is arranged in front of the support part and thus in front of a recess in the support part for the entry of the air.

[0011] The baffle in the area of ​​the inlet opening of the respective flow channel prevents, on the one hand, an unwanted view into the respective flow channel in the area of ​​the inlet opening, and on the other hand, the flow of air in the area of ​​the inlet opening of the respective flow channel can be advantageously guided via the baffle.

[0012] The multi-part, especially two-part, design of the grille, consisting of a support part and a visible part, is particularly advantageous. The support part allows the grille to be mounted precisely to the fender, compensating for any tolerances in the fender. The visible part is mounted to the fender via the support part. The horizontally extending louvers of the visible part allow for particularly favorable airflow guidance in the inlet area of ​​the respective air duct.

[0013] Preferably, the support part of the respective trim panel rests against an edge of the respective fender via at least one pin, wherein preferably at least one preload element of the support part of the respective trim panel presses the at least one pin of the support part against the edge of the respective fender. This is preferred in order to compensate for tolerances in the area of ​​the fender and to mount the support part, and thus the visible part of the trim panel, with high precision without forming a disruptive gap on the fender.

[0014] Preferably, the support part of the respective aperture has at least one locking hook and / or at least one locking opening for attaching the viewing element of the respective aperture. This allows the viewing element to be mounted particularly advantageously on the support part.

[0015] The support part of each cover plate has cover areas for concealing sections of the fender. This is advantageous for obscuring the view of specific sections of the fender. This allows the view of the fender's inner surface and any fasteners located within it to be hidden.

[0016] Preferably, the horizontally extending lamellae of the visible part of the respective aperture form airflow guiding surfaces, wherein the airflow guiding surfaces are preferably inclined at an angle of 5° to 45°, and in particular 15° to 45°, relative to the horizontal such that, viewed in the direction of airflow, the airflow guiding surfaces rise. This allows, on the one hand, for the most complete optical coverage of the fender in the area of ​​the inlet opening of the respective airflow channel, and on the other hand, for optimal airflow guidance in the area of ​​the inlet opening of the respective airflow channel.

[0017] Preferred embodiments of the invention are described in the dependent claims and the following description. Exemplary embodiments of the invention are explained in more detail with reference to the drawing, without being limited thereto. The drawing shows: Fig. 1. A perspective view from a slightly oblique front view of the front of a motor vehicle, Fig. 2 a detail of the Fig. 2 together with an aperture in the area of ​​an inlet opening of a flow channel, Fig. 3 the cross-section III-III of the Fig. 2, Fig. 4 the cross-section IV-IV of the Fig. 2, Fig. 5 the cross-section VV of the Fig. 2, Fig. 6 the cross-section VI-VI of the Fig. 2, Fig. 7 the cross section VII-VII of the Fig. 2, Fig. 8 the aperture of the Fig. 2 in standalone view in a first side view, Fig. 9 the aperture of the Fig. 8 in a opposite Fig. 8 Side view rotated 180° around a vertical axis, Fig. 10 an exploded view of the Fig. 8, Fig. 11 an exploded view of the Fig. 9, Fig. 12 the aperture of Fig. 8 in a opposite Fig. 8 Side view rotated 90° around a vertical axis, Fig. 13 the aperture of Fig. 8 in a opposite Fig. 8 Side view rotated 270° around a vertical axis, and Fig. 14 a supporting body of the aperture of the Fig. 8 to 13 in a mounting position on the fender.

[0018] Fig. Figure 1 shows a section of a motor vehicle 20 viewed from a front oblique angle, wherein in Fig. 1 a headlight 21, a fender 22, a hood 23, a front wheel 24 and a rear wheel 25 are visible.

[0019] To the side of the in Fig. In the front headlight 21 shown in Figure 1, specifically between the front headlight 21 and the fender 22, a flow channel 26 for air is formed, through which air can be guided from an area in front of the front headlight 21 to an area behind the front headlight 21. This serves to reduce the dynamic pressure of the air in front of the front headlight 21 and thus to reduce the drag coefficient (Cd) of the vehicle 20. Fig. Figure 1 illustrates the airflow LS, particularly in the area upstream and downstream of the headlight 21. An inlet opening 27 of the flow channel 26 is formed in an area upstream of the headlight 21. The airflow LS, guided through the flow channel 26, can enter a wheel housing 29, which accommodates a front wheel 24, via an outlet opening 28 of the flow channel 26, and then flow out of the wheel housing 29 and subsequently laterally past the vehicle 20.

[0020] In the area of ​​the inlet opening 27 of the respective flow channel 26, specifically viewed in the longitudinal direction of the vehicle upstream of the respective headlight 21, a baffle 30 is arranged. The baffle 30 allows air to enter the respective flow channel 26 via the inlet opening 27, guides the airflow in the area of ​​the inlet opening 27 of the respective flow channel 26, and obscures a direct view from the outside of sections within the respective flow channel 26, in particular of the inner side of the fender 22 and of fasteners installed in this area, as well as of the housing of the headlight 21. The baffle 30 in the area of ​​the inlet opening 27 of the respective flow channel 26 formed between the headlight 21 and the fender 22 therefore performs both flow-guiding and design functions.

[0021] The respective aperture 30 is preferably designed in multiple parts, particularly preferably in two parts. This shows Fig. 8 to 13 different views of a two-part aperture 30. Fig. Figures 3 to 6 show different cross-sections through the aperture 30 in a state installed on the motor vehicle 20.

[0022] The cover 30 has a support part 31 and a viewing part 32. The cover 30 is mounted to the respective fender 22 via the support part 31. The respective viewing part 32 is attached to the support part 31 and thus mounted to the fender 22 via the support part 31.

[0023] The support part 31 is essentially frame-like. The visible part 32 is also essentially frame-like and has horizontally extending louvers 33. The louvers 33 extend horizontally between a circumferential, triangular frame 34 of the visible part 32, the frame 34 of the visible part 32 being mounted on the support part 31. As already stated, the support part 31 is mounted on the fender 22.

[0024] The visible part 32 of the aperture 30 is positioned in front of the support part 31 of the aperture 30 when installed. Air entering the respective flow channel 26 in the area of ​​the inlet opening 27 of the respective flow channel 26 flows over the louvers 33 of the visible part 32 of the aperture 30 and through a recess 45 located behind it and defined by the support part 31 into the respective flow channel 26.

[0025] The carrier part 31 of the cover 30 has cover areas 35, 36 which serve to cover sections, namely inner sections, of the fender 22 and, if applicable, a housing of the headlight 21. Section 35 (see Fig. 14) serves in particular to cover the inside of the fender 22. Area 36 also serves to cover the inside of the fender and the fasteners installed therein.

[0026] The support part 31 of the respective cover 30, particularly adjacent to the cover area 35, has at least one pin 37. In the exemplary embodiment, two pins 37 are provided, by means of which the support part 30 is attached to the fender 22 in the state mounted on the fender 22 (see Fig. 14) abuts an edge 38 of the fender 22, wherein this edge 38 is a rolled edge 38 of the fender 22.

[0027] On the opposite side of the carrier part 31 of the respective aperture 30, at least one pre-tensioning element 39 is formed. The pre-tensioning element 39 is in particular designed in the form of a so-called omega clip.

[0028] The preload element 39 rests against a contour of the fender 22 and presses the support part 31 with the pin(s) 37 against the flanged edge 38 of the fender 22. This preload, provided by the at least one preload element 39, ensures precise and highly accurate mounting of the support part 31 and thus of the cover 30 on the fender 22, despite any tolerances of the fender 22.

[0029] Additionally, the support part 31 of the respective cover 30 has a mounting section 40 for a fastening screw, by means of which the support part 31 can be fixed to the fender 22 in the position in which it is pressed against the flanged edge 38 of the fender 22 by means of the at least one preloading element 39 with the pin 37. A mounting clip 41 is preferably arranged between the mounting section 40 of the support part 31 and the fender 22, through which a fastening screw inserted into the mounting section 40 can extend. This mounting clip 41 preferably has an internal thread which interacts with an external thread of the fastening screw.

[0030] Furthermore, in the preferred embodiment shown, the support part 31 has at least one locking hook 42 which interacts with the visible part 32 to mount the visible part 32 to the support part 31. The respective locking hook 42 of the support part 31 preferably engages in a groove-like or groove-like contour 46 of the visible part 32. In addition to the recess 45, the support part 31 also has a locking opening 43 into which a corresponding locking hook 44 of the visible part 32 can be inserted to fasten it to the support part 31. A locking hook 44 of the visible part 32 also engages in the recess 45 of the support part 31, which serves to guide the airflow. The locking hooks 44 of the visible part 32 partially encompass a contour of the support part 31 that defines the recess 45 or the locking opening 43.

[0031] To mount a cover 30 on the respective fender 22, the support part 31 is first mounted on the fender 22, whereby the at least one preload element 39 presses the support part 31 with the at least one pin 37 against the flanged edge 38 of the fender 22. The support part 31 of the cover 30 can be fixed in this position on the fender 22 by means of a fastening screw that extends through the fastening section 40 of the support part 31.

[0032] The visible part 32 is then mounted on the carrier part 31 by the locking hooks 42 of the carrier part 31 engaging in a contour 46 of the visible part 32, and by the locking hooks 44 of the visible part 32 engaging in the recess 45 and in the locking opening 43 of the carrier part 31.

[0033] A further slot-like recess 48 on the support part 31, into which a projection 49 of the visible part 32 engages, serves to align or pre-position the visible part 32 on the support part 31.

[0034] The visible part 32 has the louvers 33, which extend horizontally between the frame 34 of the visible part 32. The louvers 33 form flow-guiding surfaces 47 for the air. Preferably, as is best Fig. As can be seen from Figure 6, the flow-guiding surfaces 47 of the lamellae 33 are inclined relative to a horizontal plane such that, viewed in the direction of airflow along the flow-guiding surfaces 47, the flow-guiding surfaces 47 and thus the lamellae 33 rise or run upwards. In particular, the lamellae 33 or the flow-guiding surfaces 47 form an angle between 5° and 45°, and especially an angle between 15° and 45°, with a horizontal plane.

[0035] The support part 31 of the cover 30 compensates for tolerances of the fender 22, so that the visible part 32 of the cover 30 can be attached to the fender 22 with high precision and without any disruptive gap to the fender 22 and the headlight 21 via the support part 31. The at least one preload element 39 and the at least one pin 37 of the support part 31 serve this purpose in particular.

[0036] Furthermore, the carrier part 31 of the aperture 30 covers inner sections of the fender 22 in the area of ​​the inlet opening 27 of the respective flow channel 26, namely via the covering areas 35, 36 of the carrier part 31.

[0037] The locking hooks 42 of the carrier part 31, which serve to fasten the visible part 32 to the carrier part 31, are not visible from the outside when mounted on the fender 22.

[0038] Furthermore, the locking hooks 44 of the visible part 32, which also serve to fasten the visible part 32 to the support part 31, are not visible from the outside when mounted on the fender 22.

[0039] The visible part 32 has the louvers 33, which serve to guide the airflow and largely prevent direct viewing into the interior of the respective flow channel 26.
