Description

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

[0002] DE 10 2008 017 896 A1 discloses a front end section of a motor vehicle with a front fairing that includes air intake openings in a central area and lateral areas. A central air guide element is positioned behind a central air intake opening of the front fairing, which is formed in the central area of ​​the same. A lateral air guide element is positioned behind at least one lateral air intake opening of the front fairing, which is formed in a lateral area of ​​the same. An air vane is arranged between the central air guide element and at least one lateral air guide element, and this vane can be moved between a pre-assembly position and an assembly position.

[0003] According to DE 10 2008 017 896 A1, each air vane in the pre-assembly position is folded away from the respective lateral air guide element and held by the central air guide element, whereby to transfer the respective air vane from the pre-assembly position to the assembly position, the respective air vane is folded over and can be connected to the respective lateral air guide element in the assembly position.

[0004] Based on this, the present invention aims to create a novel front end section for a motor vehicle.

[0005] This problem is solved by a front bow part according to claim 1.

[0006] According to the invention, the air vane or each air vane is folded away from the central air guide element in the pre-assembly position and held on the respective lateral air guide element, and in the assembly position can be folded back to the central air guide element and / or attached to it.

[0007] According to the invention, in the pre-assembly position, each air vane is folded away from the central air guide element and held on the respective lateral air guide element. In the assembly position, the respective air vane is folded back towards the central air guide element and can be connected to and attached to it.

[0008] According to the invention, each air vane is engaged in the assembly position by at least one connecting element, designed as a projection and located at the front when viewed in the assembly position, on the central air guide element, namely by a locking lug of the central air guide element. Furthermore, each air vane is supported in the assembly position by at least one guide element, designed as a projection and located at the rear when viewed in the assembly position, on the central air guide element and engages in a guide of the central air guide element, which is defined by ribs of the same.

[0009] According to the invention, a pivot axis around which the respective air vane can be moved from the pre-assembly position to the assembly position and vice versa is formed between the respective lateral air guide element and the air vane in the front end section, and not, as in the prior art, between the central air guide element and the respective air vane. This provides improved accessibility to connection points, particularly screw connections, of the vehicle body located behind the air guide elements, even when a relatively large air vane is pre-assembled.

[0010] No additional fasteners such as screws, rivets, or the like are required.

[0011] According to an advantageous further development, the rear wall of each air vane is designed without openings and serves to transfer air between the central air guide element and the respective lateral air guide element. Because the rear wall of the air vane is designed without openings, the air vane allows for an unimpeded and therefore effective transfer of air between the central air guide element and the respective lateral air guide element.

[0012] 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 section of a front end part of a motor vehicle according to the invention; Fig. 2 the front bow part of the Fig. 1 without front fairing; Fig. 3 a cross-section through the front bow part of the Fig. 2 along the cutting direction III-III; Fig. 4 a perspective view of the front bow section of the Fig. 2 with an air scoop in pre-assembly position; Fig. 5 a perspective view of the front bow section of the Fig. 2 with the air scoop in mounting position; Fig. 6 an upper connecting element of the air vane to a lateral air guide element; Fig. 7 a lower connecting element of the air vane to the lateral air guide element; Fig. 8 a front connecting element of the air vane to a central air guide element; Fig. 9 a rear guide element of the air vane for support against the central air guide element; Fig. 10. An air scoop in a single perspective view; and Fig. 11 a lateral air guide element which works in conjunction with an air scoop, in perspective standalone view.

[0013] The invention relates to a front end part of a motor vehicle and is described below with reference to Fig. Items 1 to 11 are described in detail. Fig. Figure 1 shows a section of a front end part 10 of a motor vehicle in front view, wherein a central air intake opening 12 is provided in a front fairing 11 of the front end part 10 in a central area and a lateral air intake opening 13 is provided to each side next to the central air intake opening 12 in lateral areas.

[0014] How Fig. Figure 2, which shows a front view of the front bow section 10 with the bow fairing 11 removed, reveals a central air guide element 14 behind the central air intake opening 12 and behind the Fig. 1 visible air inlet opening 13 a lateral air guide element 15 is positioned.

[0015] The central air guide element 14 has at least one air guide opening 16 through which air can be supplied to a central cooler located behind the central air guide element 14. Fig. 2. The lateral air guide element 15 shown, positioned laterally next to the central air guide element 14, has at least one air guide opening 17 through which air can be supplied to a lateral cooler arranged behind the lateral air guide element 15.

[0016] Between the middle air guide element 14 and the one in Fig. An air vane 18 is arranged in the 2 visible, lateral air guide element 15 positioned next to the middle air guide element 14. Fig. 2 and Fig. Figure 5 shows the air vane 18 in an assembly position, whereas Fig. Figure 4 shows the air vane 18 in a pre-assembly position.

[0017] The in Fig. 2, Fig. 4 and Fig. 5 visible air vane 18 is by folding from the pre-assembly position (see Fig. 4) into the assembly position (see Fig. 2 and Fig. 5) and vice versa, transferable from the assembly position to the pre-assembly position, whereby this folding of the air vanes 18 in Fig. 4 is visualized by a double arrow 19.

[0018] The in Fig. 2, Fig. 4 and Fig. 5 visible air vane 18 is in the pre-assembly position (see Fig. 4) folded away from the central air guide element 14 and held on the lateral air guide element 15, namely via connecting elements 20, 21. These connecting elements 20, 21 of the air vane 18 are designed as so-called hook pins which engage in corresponding openings 22, 23 in the lateral air guide element 15.

[0019] Fig. 6 and Fig. Figure 7 shows enlarged details of these connecting elements 20 and 21, which are designed as hook pins, and of the corresponding openings 22 and 23, wherein the connecting element 20 with the corresponding opening 22 forms an upper attachment point of the air vane 18 on the lateral air guide element 15 and the connecting element 21 with the opening 23 forms a lower attachment point of the air vane 18 on the lateral air guide element 15.

[0020] A pivot axis extends through the connecting elements 20, 21, which are designed as hook pins, around which the air vane 18 can be moved from the pre-assembly position to the assembly position by folding it over, whereby in the assembly position (see Fig. 2 and Fig. 5) the air vane 18 is folded down to the central air guide element 14 and can be connected to the central air guide element, namely via at least one front connecting element 24 as seen in the assembly position of the air vane 18. This shows Fig. 8, that a front connecting element 24 of the air vane 18, designed as a projection, locks into a locking lug 26 of the middle guide element 14 in the assembly position.

[0021] These front connecting elements 24 of the air blade 18, as seen in the assembly position of the air blade 18, which lock into each of a locking lug 26 of the middle guide element 14 in the assembly position, are preferably formed at the top and bottom of the air blade 18.

[0022] Viewed from the rear of the assembly position, at least one guide element 25 is formed on the air vane 18, by means of which the air vane 18 is additionally supported on the central air guide element 14 in the assembly position. According to Fig. 9 In the assembly position of the air vane 18, a rear guide element 25 designed as a projection engages in a guide 27 of the middle air guide element 14, which is defined by support ribs 28 of the same.

[0023] According to the invention, the axis of rotation about which the air vane 18 can be moved from the pre-assembly position to the assembly position and vice versa is formed between the respective lateral air guide element 15 and the air vane 18, so that, when a relatively large air vane 18 is pre-assembled, good accessibility to connection points 34, in particular screw points, of the vehicle body located behind the air guide elements 14, 15 is ensured despite the pre-assembled air vane 18.

[0024] What is the best way? Fig. As can be seen from Figure 10, which shows a perspective view of the air vane 18, the air vane 18 defines a guide channel 29 for air, which is defined by a rear wall 30, an upper wall 31 and a lower wall 32, whereby air can be transferred between the middle air guide element 14 and the lateral air guide element 15 via the air guide channel 29.

[0025] The rear wall 30 is designed without openings, so that the air vane 18 ensures an unimpeded airflow through the air guide duct 19.

[0026] The air guide channel 29, which is provided by the guide vane 18, complements, in the assembly position of the guide vane 18, an air guide channel 33 of the lateral air guide element 15, which opens into the air guide opening 17 of the same.

[0027] Preferably, a lateral air guide element 15 with an air vane 18 arranged between the lateral air guide element 15 and the central air guide element 14 is positioned exclusively behind a lateral air inlet opening 13 on one side of the central air inlet opening 12. However, this can also be the case in the area of ​​both lateral air inlet openings 13 and thus on both sides of the central air inlet opening 12. Reference symbol list 10 Front bow section 11.
