Technical Field

The present invention relates to an air guide device for a vehicle.

Background

A vehicle with an air guide device formed as a rear spoiler module is known from DE 102010000634 a 1. The air guide device can be mounted to the body structure of the vehicle by means of a bracket part called mounting bracket. The carriage part receives a spoiler which can be displaced by a servomotor between a retracted rest position and an extended working position. The air guide device is a preassembled unit, wherein the carrier part is supported centrally on the vehicle body by means of the centering unit.

Another air guide device for a vehicle is known from DE 102014118496 a1, which is arranged in the rear region of the vehicle. The disclosed air guide device has an air guide element formed as a spoiler, which can be displaced between a rest position and an operating position by means of a servomotor. In order to deflect the air guide element, a hinge assembly is used, which extends through the passage opening of the lower housing, wherein a servomotor engages in the hinge assembly to deflect the air guide element.

DE 102009033695 a1 discloses a rear region of a motor vehicle, in which a spoiler drive of an air guide is mounted on a bracket, which is fastened to the body structure of the motor vehicle. The rack carrier is plugged or held by means of plug connectors on holding rails, wherein these holding rails are mounted on the vehicle body structure.

Disclosure of Invention

The invention aims to create a novel air guiding device. This object is achieved by an air guiding device as described below.

The air guide device according to the invention has a stationary bracket part which can be mounted on the body structure of the vehicle by means of mounting brackets, wherein each of these mounting brackets is connected to the body structure at a first section and to the bracket part at a second section.

The air guide device according to the invention also has an air guide element which is displaceable relative to the fixed bracket part between a retracted rest position and a deployed working position.

The air guide device according to the invention also has a link mechanism with a plurality of links, by means of which the air guide element can be displaced relative to the carrier part, wherein the links of the link mechanism are supported on the first mounting bracket.

The air guide device according to the invention also has a servomotor which acts on the link movement mechanism to offset the air guide element relative to the carrier part, wherein the servomotor is supported on the second mounting bracket.

The air guide device according to the invention is a carrier part made of plastic, which is connected to a mounting bracket made of plastic or metal by means of a clip connection (Verclipsen Verbunden).

In the air guide device according to the invention, the carrier part is mounted on the vehicle body structure by means of a mounting bracket, the air guide device having a fixed carrier part and an air guide element which can be displaced relative to the carrier part. Each of these mounting brackets is connected to the body structure at a first section and to the bracket part at a second section. The carrier part made of plastic is connected to the mounting brackets made of plastic or metal by means of a clip connection. It is particularly preferred to connect the bracket parts (which may also be referred to as mounting brackets) to mounting brackets by means of which the bracket parts are finally connected to the vehicle body structure.

According to an advantageous development, a ball-or joint-like anchoring element is formed on the carrier part. Notches are formed in the mounting brackets, into which connecting elements with spherical or socket-like depressions are inserted. The ball-or socket-like anchoring elements of the carrier part engage in the ball-or socket-like recesses of the connecting elements. This connection of the bracket part to the second section of the mounting bracket is not only simple, but thereby also gives an acoustic decoupling between the bracket part and the mounting bracket. This prevents undesirable noise generation in the region of the mounting bracket or bracket part of the air guide.

The connecting element is preferably formed from rubber or a rubber-elastic material. Particularly advantageous acoustic decoupling can be provided when the connecting element is preferably formed from rubber or a rubber-elastic material.

The connecting elements preferably have a recess on the outer cover surface, into which a material connection of the mounting bracket, which defines the respective recess of the mounting bracket, engages in a form-fitting manner, in particular so that a groove-and-tongue connection is formed between the respective connecting element and the respective mounting bracket. Such a connection between the connecting element and the mounting bracket is particularly preferred.

Detailed Description

Fig. 1 shows a perspective view of an air guide device 10 for a vehicle (i.e. for a passenger motor vehicle), which is mounted on a body structure 15 of the vehicle, in particular behind a rear window of the vehicle, in a rear region of the vehicle.

The air guide device 10 has a fixed carrier part 11 and an air guide element 29 which can be displaced relative to the fixed carrier part 11. Fig. 1 shows the air guide 10 in a state in which the air guide element 29 is in a retracted rest position. Relative to this retracted rest position, the air guide element 29 can be displaced relative to the fixed carrier part 11, in particular into a deployed working position (not shown in the figures).

Fig. 2, however, shows the air guide device 10 when the air guide element 29 is lifted or removed and thus opens up the view from above to the fixed carrier part 11.

The stationary support part 11 has in the embodiment shown a double-coated or double-layered structure consisting of two parts 11a and 11 b. Portion 11a is the bracket part itself, and portion 11b is the visually attractive lining of part 11 a.

The bracket part 11 (which may also be referred to as a mounting bracket) may be mounted on the vehicle body structure 15 by mounting brackets 12, 13, and 14. The first section 12a, 13a or 14a can connect the respective mounting bracket 12, 13 or 14 to the body structure 15. The respective mounting bracket 12, 13 or 14 is connected to the carrier part 11, in particular to the part 11a thereof, by means of a second section 12b, 13b or 14b opposite the first section 12a, 13a or 14 a.

The air guide device 10 has a link movement mechanism 17 with a plurality of links 16 and a servomotor 18.

The servomotor 18 is mounted on the intermediate mounting bracket 14 seen in fig. 1 and 2. The central mounting bracket 14, which engages on the central section of the carrier part 11, serves not only for fastening the carrier part 11 to the body structure 15, but also for receiving and supporting the servomotor 18.

The servomotor 18 is coupled to the link movement mechanism 17 in order to displace the air guide element 29, and therefore the air guide element between the retracted rest position and the extended working position, relative to the carrier part 11 via the link 16 of the link movement mechanism 17. The link kinematics 17 here has a plurality of links 16, of which only a few links 16 are visible in fig. 1 and 2, namely the links 16 supported on the lateral mounting brackets 12 and 13, wherein the lateral mounting brackets 12 and 13 engage on lateral sections of the carrier part 11 and are therefore positioned laterally next to the central mounting bracket 14.

The invention relates here in particular to the fastening of a bracket part 11 (which may be referred to as mounting bracket) to the second section 12b, 13b, 14b of the respective mounting bracket 12, 13 or 14. Fig. 4 and 5 show a schematic cross section through the coupling region or connecting region of the carrier part 11 with a mounting bracket, which can be a mounting bracket 12, 13 or 14, respectively.

The bracket part 11 formed of plastic, i.e. the portion 11a thereof, is connected with the mounting brackets 12, 13 and 14 made of plastic or metal by a clip connection.

There is no need to mount a metal sleeve or a metal insert in the bracket part 11 in order to connect the bracket part 11 with the mounting brackets 12, 13 and 14, in order to thus screw the bracket part 11 with the respective mounting bracket 12, 13 or 14. Such a screw connection is omitted. But rather clamps the bracket part 11 together with the mounting bracket 12, 13 or 14.

Fig. 4 and 5 show two possible variants for the clip connection of the carrier part 11 to the mounting brackets 12, 13 and 14, the variant of fig. 4 being particularly preferred.

In the variant of fig. 4, a spherical or articular-like anchoring element 19 is formed on the support element 11, i.e. on the portion 11a of the support element 11. Notches 20 are formed in the respective mounting bracket 12, 13 or 14 (i.e. in its respective second section 12b, 13b or 14b), into which connecting elements 21 with ball-or socket-like recesses 22 are inserted. The ball-or socket-shaped anchoring element 19 of the carrier part 11 snaps into the ball-or socket-shaped recess 22 of the connecting element 21.

The connecting element 21 is preferably a connecting element formed of rubber or a rubber-elastic material. These connecting elements are formed cylindrically or circularly in cross section, wherein a circumferential groove 24 is introduced into the outer cover 23 of the respective connecting element 21, into which groove a material web 25 of the respective mounting bracket 12, 13 or 14, which material web defines the respective recess 20, engages in a form-fitting manner to form a tongue-and-groove connection.

The variant of fig. 4 is not only preferably used to simply connect the bracket part 11 with the mounting brackets 12, 13 and 14, but the variant of fig. 4 also provides for acoustic decoupling of the bracket part 11 from the mounting brackets 12, 13 and 14 and thus from the body structure 15. Therefore, the generation of undesirable noise can be avoided.

Fig. 5 shows a variant of the clip connection of the carrier part 11 to the respective mounting bracket 12, 13 and 14, wherein barb-like anchoring elements 26 are formed on the carrier part 11, which anchoring elements engage in recesses 27 of the respective mounting bracket 12, 13 or 14. In this case, the barb-like anchoring elements 26 are formed on the portion 11a of the carrier part 11 and have lead-in bevels 28, by means of which the barb-like anchoring elements 26 can be snapped into and held in the respective recesses 27 of the respective mounting bracket 12, 13 or 14. Thus, the bracket part 11 can also be simply connected with the respective mounting bracket 12, 13 or 14 by means of such a snap-on connection without the acoustic decoupling provided by the variant of fig. 4.

The invention allows a simple and reliable connection of the bracket part 11 to the mounting brackets 12, 13 and 14, preferably providing acoustic decoupling. The number of parts necessary is reduced by the elimination of inserts and screws. The installation cost and the time necessary for installation can be reduced.
