Description

[0001] The invention relates to a motor vehicle front section according to the preamble of claim 1. Furthermore, the invention relates to a motor vehicle with a motor vehicle front section and an air flap or air scoop for a motor vehicle.

[0002] From DE 10 2010 010 655 A1, a motor vehicle with a motor vehicle body is known, which has a front part with at least one grill-like air intake opening, wherein at least one air intake duct is formed behind the air intake opening, by means of which air flowing through the air intake opening can be supplied to a cooler, and wherein at least one acoustic signaling device having a sound funnel is positioned behind the air intake duct, wherein the air intake duct is provided with a perforation, wherein the perforation is arranged in the area of ​​the sound funnel, and wherein a signal emitted by the acoustic signaling device can be emitted to the outside via the perforation.

[0003] DE 10 2010 017 320 A1 discloses a motor vehicle front part according to the preamble of claim 1.

[0004] DE 10 2010 010 655 A1 reveals another motor vehicle front part.

[0005] The object of the invention is to further improve the emission of an acoustic signal to the outside in a motor vehicle front section with at least one air intake opening, behind which an air intake duct is formed, which may be provided with a perforation.

[0006] The problem is solved by a motor vehicle front part according to claim 1, by a motor vehicle according to claim 7 and by an air flap or air scoop for a motor vehicle according to claim 8.

[0007] The front section of the vehicle has at least one air intake opening, behind which an air intake duct is formed. This duct may be perforated to allow an acoustic signal to be emitted to the outside. The air intake opening can be closed or sealed by an air guide device, in particular by an air flap or an air vane, which is also perforated. The air flap allows for simple regulation of the air supply through the intake opening. When the air flap is open, the emission of an acoustic signal to the outside is not, or only minimally, affected. When the air flap closes the intake opening, the perforations in the air flap allow an acoustic signal to be emitted to the outside when required.Unlike an air flap, an air scoop is fixed in place, for example behind an air intake opening of an inlet grille.

[0008] The perforation includes funnel-shaped and / or teardrop-shaped holes. The funnel shape of the holes improves the signal transmission to the outside. Teardrop-shaped holes further improve the transmission of the acoustic signal to the outside.

[0009] Another preferred embodiment of the vehicle front section is characterized in that the holes are formed on the rear side of the air guide device, in particular the air flap or air scoop. The holes can be teardrop-shaped. The term "rear side" refers to a longitudinal direction of the vehicle, also known as the x-direction. The front end of the vehicle is the nose section with the vehicle front section. The rear side of the air flap or air scoop faces the rear of the vehicle. The teardrop shape of the holes on the rear side of the air flap or air scoop improves the emission of the acoustic signal to the outside. Alternatively or additionally, the holes on the front side of the air flap or air scoop can also be teardrop-shaped.

[0010] Another preferred embodiment of the vehicle front section is characterized in that the holes on one or the rear side of the air guide device, in particular the air flap or air vane, are funnel-shaped. This further improves the emission of the acoustic signal to the outside. The diameter of the holes can advantageously decrease linearly from the outside to the inside. Alternatively or additionally, the holes on one or the front side of the air flap or air vane can be funnel-shaped.

[0011] Another preferred embodiment of the vehicle front section is characterized in that the air flap has a receptacle for a temperature sensor. The receptacle for the temperature sensor can be designed as a simple through-hole.

[0012] Another preferred embodiment of the vehicle front section is characterized in that the air guide device, in particular the air flap or air vane, has a sound collar on one or the rear side. This further improves the emission of the acoustic signal to the outside.

[0013] The invention further relates to a motor vehicle according to claim 7 with a previously described front section of the motor vehicle. The front section of the motor vehicle advantageously comprises two previously described air flaps or air vanes, which are provided with a perforation according to the invention.

[0014] The invention further relates to an air flap or air scoop according to claim 8 for a previously described motor vehicle. The air flap or air scoop is separately tradable.

[0015] Further advantages, features, and details of the invention will become apparent from the following description, in which various exemplary embodiments are described in detail with reference to the drawing. The drawing shows: Fig. 1 a perspective view of a motor vehicle front section with two air flaps from the front; Fig. 2 a perspective view of one of the air flaps made of Fig. 1. Looking at the inside or back; and Fig. 3 A perspective view of an air scoop with perforations.

[0016] In Fig. Figure 1 shows the front section 1 of a motor vehicle in a perspective view from the front. The front section 1 includes air intake openings 3, 4, 5, 6.

[0017] The air inlet 3 is centrally located and equipped with a grille structure 8. Air inlets 5 and 6 are located to the side of the central air inlet 3. Air inlet 4 is located below the central air inlet 3 and is equipped with a grille structure 9.

[0018] Two lateral end regions of the supply air opening 4 can be closed by air flaps 11 and 12. The air flaps 11 and 12 are shown in their closed position, in which they close the lateral end regions of the supply air opening 4.

[0019] In Fig. Figure 2 shows the air flap 12 in perspective, looking at its rear or inner side. In its installed state, the air flap 12 pivots about an axis 20 between its Fig. The air flap 12 is movable between the closed position shown in Figure 1 and an open position (not shown). At the ends of the pivot axis 20, the air flap 12 has mounting elements 21, 22, which allow the air flap 12 to be pivotably attached to the front section of the vehicle (1 in Figure 1). Fig. 1) enable.

[0020] The air flap 12 includes a receptacle 25 for a temperature sensor (not shown). Furthermore, the air flap 12 includes a plurality of through holes or perforations 30, forming a perforation 31. The holes 30 are arranged along circular arcs 33, 34 and lines 35 to 37, 38 to 40. In addition, the holes 30 have a teardrop shape.

[0021] Air flap 12 is also located on its Fig. The reverse side shown in Figure 2 is provided with a sound collar 45. To improve sound emission to the outside, the through-holes 30 are funnel-shaped. To emphasize the dynamics, the diameter of the holes 30 decreases linearly from the outside to the inside.

[0022] In Fig. Figure 3 shows an air vane 51 with a perforation 54 in perspective. The air vane 51 is stationary, preferably behind the in Fig. 1. The grid structure 8, designated as 8, is arranged and represents an inlet grid. The air vane 51, for example, is located above the left air flap (11 in). Fig. 1) arranged behind an air intake opening in the inlet grille.
