Description

[0001] The invention relates to a rear-mounted air guide device for a motor vehicle and a motor vehicle.

[0002] DE 42 07 658 A1 discloses a rear-mounted air guide device for a motor vehicle with a spoiler blade. The spoiler blade can be moved between at least two spoiler blade positions along a first displacement movement by means of a kinematic mechanism and a drive mechanism interacting with the kinematic mechanism. Starting from the second spoiler blade position, the spoiler blade can further be moved into a third spoiler blade position by means of a further drive mechanism, which also acts on the spoiler blade via a kinematic mechanism.

[0003] DE 11 2018 002 909 T5 discloses a rear air guide device for a motor vehicle according to the preamble of claim 1.

[0004] EP 2 855 245 B1, DE 10 2017 209 949 A1, DE 10 2017 210 023 A1 and DE 42 07 658 A1 disclose further rear air guide devices for a motor vehicle.

[0005] There is a need for a novel rear air guide device for a motor vehicle, which, with its simple design, can be advantageously moved between different spoiler blade positions.

[0006] The object of the invention is to create a corresponding rear air guidance device for a motor vehicle and a motor vehicle with such a rear air guidance device.

[0007] This problem is solved by a rear air guide device of a motor vehicle according to claim 1 and a motor vehicle according to claim 4.

[0008] A second drive is integrated into the spoiler blade, with the help of which the spoiler blade can be moved between at least two spoiler blade positions along a second displacement movement independently of the first displacement movement.

[0009] In the air guide device, the spoiler blade can be moved between at least two spoiler blade positions along a first displacement movement by means of a kinematic mechanism and a first drive operatively connected to the kinematic mechanism. The second drive is integrated into the spoiler blade of the rear air guide device according to the invention. By means of the second drive, the spoiler blade can be moved between at least two spoiler blade positions along a second displacement movement, independently of the first displacement movement. This allows for an advantageous displacement of the rear air guide device between spoiler blade positions with a simple design.

[0010] The second drive, in particular together with the spoiler blade, can be moved between at least two spoiler blade positions along the first displacement movement. This ensures advantageous displacement of the spoiler blade between different spoiler blade positions, even with a simple design.

[0011] The kinematic mechanism uses the first drive to move the spoiler blade between a first spoiler blade position and a second spoiler blade position along a linear or arc-shaped path in the longitudinal direction of the vehicle. The second drive pivots the spoiler blade in the first spoiler blade position between the first and third spoiler blade positions about an axis extending transversely to the vehicle. Additionally, the second drive pivots the spoiler blade in the second spoiler blade position between the second and fourth spoiler blade positions about an axis extending transversely to the vehicle. This simple design allows for advantageous repositioning of the rear air deflector.

[0012] The second drive can also pivot the spoiler blade around an axis extending laterally to the vehicle during its repositioning between the first and second spoiler blade positions. This, too, allows for a particularly advantageous repositioning of the spoiler blade between different spoiler blade positions, even with a simple design.

[0013] 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 rear air guide device of a motor vehicle in a first state, Fig. 2 the rear air guide device of a motor vehicle in a second state.

[0014] Fig. 1 and Fig. Figures 2 each show a section of a motor vehicle in the area of ​​a rear body part 11, a rear window 12 and a rear air guide device 13 positioned behind the rear window 12. Fig. Figure 1 shows the air guide device 13 in a first state, in Fig. Figure 2 shows the air guide device 13 in different states.

[0015] The air guide device 13 has a spoiler blade 14. The spoiler blade 14 can be displaced between at least two spoiler blade positions along a first displacement movement 15 by means of a kinematic mechanism 16 and a first drive 17 operatively connected to this kinematic mechanism 16. In the illustrated embodiment, the kinematic mechanism 16 is a linkage kinematic mechanism which moves the spoiler blade 14 between the positions shown in the first drive 17. Fig. 1 shown first spoiler leaf position into the in Fig. The second spoiler blade position, shown in solid lines, is shifted along an arc-shaped path. Fig. 2 is the first spoiler leaf position of the Fig. 1 shown in dashed lines. During the relocation of the spoiler leaf 14 between the first spoiler leaf position of the Fig. 1, which is in Fig. 2 is shown in dashed lines, and the one in Fig. In the second spoiler blade position shown in solid lines 2, the spoiler blade 14 is therefore displaced both longitudinally to the rear and vertically to the top of the vehicle, along the arc-shaped path. This arc-shaped path corresponds to the first displacement movement 15.

[0016] It should be noted at this point that the displacement of the spoiler blade 14 between the first spoiler blade position and the second spoiler blade position can also be effected via a different kinematics in conjunction with the first drive 17, which then displaces the spoiler blade 14 between the first spoiler blade position and the second spoiler blade position exclusively translationally, i.e. along a translational path.

[0017] The first drive 17 for the spoiler blade 14 is arranged outside the spoiler blade 14 and is fixedly attached or mounted to the body part 11.

[0018] A second drive 18 for the spoiler blade 14 is integrated into the spoiler blade 14. With the aid of this second drive 18, the spoiler blade 14 can be displaced between at least two spoiler blade positions along a second displacement movement 20, independently of the first displacement movement 15, which is provided by the kinematics 16 and the first drive 17.

[0019] Thus, in Fig. 1 and Fig. 2 provided that the second drive 18 pivots the spoiler blade 14 about an axis 19 extending in the transverse direction of the vehicle.

[0020] It is provided that the second drive 18 engages the spoiler blade 14 in the first spoiler blade position of the Fig. 1 pivots around axis 19 between the first spoiler blade position and a third spoiler blade position.

[0021] Furthermore, it is provided that the second drive 18 will engage the spoiler blade 14 in the Fig. 2 shown in solid lines, the second spoiler blade position and the one in Fig. 2 the fourth spoiler blade position shown in dashed lines pivots around the axis 19 extending in the transverse direction of the vehicle, with this pivoting movement then corresponding to the second displacement movement 20.

[0022] Furthermore, it can be provided that the second drive 18 pivots the spoiler blade 14 during the relocation of the spoiler blade 14 between the first and second spoiler blade positions of the spoiler blade 14 about the axis 19 extending in the transverse direction of the vehicle.

[0023] The displacement of the spoiler blade 14 along the first displacement movement 15, provided by the kinematics 16 and the first drive 17, and the displacement of the spoiler blade 14 along the second displacement movement 20, provided by the drive 18, occur independently of each other. This means that the displacement can occur when the spoiler blade 14 is in the first spoiler blade position, the second spoiler blade position, or during the displacement of the spoiler blade 14 between the first and second spoiler blade positions. For this purpose, the second drive 18 is integrated into the spoiler blade 14 and can be displaced together with the spoiler blade 14 between the first and second spoiler blade positions.

[0024] In Fig. Figure 1 shows a rear light 21 of the motor vehicle, which is positioned below the spoiler leaf 14 in all spoiler leaf positions.

[0025] The invention allows, with a simple design of the rear air guide device 13, an advantageous relocation of a spoiler blade 14 of the rear air guide device 13 between different spoiler blade positions.
