Description

[0001] The invention relates to a spoiler arrangement and a motor vehicle with a spoiler arrangement.

[0002] Motor vehicles with a spoiler arrangement are known in the prior art, in which a spoiler blade is arranged at the rear of the vehicle. Motor vehicles with a rigidly arranged spoiler blade are known, in which the spoiler blade is spaced from the rear transversely to the direction of travel and can be surrounded by air on both its upper and lower sides.

[0003] Motor vehicles are also known in which a spoiler blade is arranged in an articulated manner at the rear, which is either lowered following the contour of the rear or which can be raised in such a way that the rear end of the spoiler blade is raised.

[0004] DE 10 2014 110 394 A1 also discloses a motor vehicle with a spoiler arrangement, in which the spoiler arrangement has two spoiler blades, wherein a first spoiler blade is articulated and pivotably arranged at the rear of the motor vehicle and a second spoiler blade is provided in such a way that it is articulatedly fastened to the rear end of the first spoiler blade, in such a way that the two spoiler blades can be arranged together from a basic position in which they are arranged in a planar alignment with one another and are arranged lying flat at the rear of the motor vehicle following the contour of the rear.In a first raised position, the two spoiler blades are still arranged in a flat alignment with one another, with the first spoiler blade being deflected at its articulated linkage such that the two spoiler blades protrude at an angle from the rear of the motor vehicle and result in an overall flat spoiler blade contour. In a second raised position, the two spoiler blades are no longer arranged in a flat alignment with one another, but the second rear spoiler blade is deflected upwards at its articulated linkage of the first spoiler blade, with the first spoiler blade still being deflected at its articulated linkage at the rear of the motor vehicle so that the two spoiler blades protrude at an angle from the rear of the motor vehicle and result in a progressively increasing angulation of the two spoiler blades.This has the disadvantage that the spoiler arrangement has essentially the same length in every extended position and thus not only increases downforce but also has undesirable aerodynamic effects that lead to increased fuel consumption, which must be avoided.

[0005] DE 10 2013 106 400 A1 discloses a spoiler arrangement with a first spoiler blade and with a second spoiler blade, wherein the first spoiler blade is arranged displaceably and the second spoiler blade is arranged displaceably such that the first spoiler blade and the second spoiler blade are adjustable in a first retracted state and in a second extended state, wherein the first spoiler blade and the second spoiler blade are each arranged one above the other in a retracted position in the first retracted state, such that the first spoiler blade covers the second spoiler blade, wherein the first spoiler blade and the second spoiler blade are each arranged in an extended position in the second extended state, wherein the first spoiler blade is raised to a first raised position and the second spoiler blade is extended such thatthat it is arranged in the extension of the first spoiler blade behind the first spoiler blade.,

[0006] US 10 611 417 B2 discloses a spoiler arrangement with two spoiler blades which are hinged to one another so that the second spoiler blade can be pivoted relative to the first spoiler blade, wherein the first spoiler blade and the second spoiler blade can also be pivoted together.

[0007] JP H02 - 6 281 A discloses a spoiler arrangement with two spoiler blades which are arranged either one above the other in one arrangement or in a second arrangement in extension to each other.

[0008] DE 10 2014 105 513 A1 discloses a spoiler arrangement with a spoiler blade that can be adjusted to different positions.

[0009] The object is to create a spoiler arrangement that is improved over the prior art, promotes a reduction in fuel consumption, and is also capable of improving the downforce of the motor vehicle. It is also the object of the present invention to create a motor vehicle with an improved spoiler arrangement.

[0010] The problem of the spoiler arrangement is solved with the features of claim 1.

[0011] An embodiment of the invention relates to a spoiler arrangement with a first spoiler blade and with a second spoiler blade, which can be arranged in particular at the rear of a motor vehicle, wherein the first spoiler blade is arranged displaceably and the second spoiler blade is arranged displaceably, such that the first spoiler blade and the second spoiler blade can be adjusted in a first retracted state, in a second extended state and in a third extended state, wherein the first spoiler blade and the second spoiler blade are each arranged one above the other in a retracted position in the first retracted state, such that the first spoiler blade covers the second spoiler blade, wherein the first spoiler blade and the second spoiler blade are each arranged in an extended position in the second extended state,wherein the first spoiler blade is raised to a first raised position and the second spoiler blade is extended such that it is arranged behind the first spoiler blade in the extension of the first spoiler blade, and wherein the first spoiler blade and the second spoiler blade are arranged one above the other in the third extended state such that the first spoiler blade is arranged in a second raised position and the second spoiler blade is arranged substantially below the first spoiler blade in its retracted position. This ensures that the spoiler arrangement produces different effects in different states. In the first state, the spoiler arrangement does not produce any special effect because it is in the retracted state. In the second state, the spoiler arrangement is in a fuel-saving state, and in the third state, the spoiler arrangement is in a downforce-enhancing state.

[0012] In an advantageous embodiment, it is accordingly expedient if the first retracted state is a resting state of the spoiler arrangement, in which both spoiler blades are retracted, the second extended state is an efficiency state in which air resistance is reduced, and the third extended state is a performance state in which downforce is improved. Thus, by adjusting the spoiler arrangement, particularly in curves, improved power transmission to the ground is achieved.

[0013] In a further embodiment, it is also expedient if the first spoiler blade, in the first retracted state, is arranged such that it essentially follows the contour of the rear of the motor vehicle. This essentially results in a contour that does not cause any particular flow effects of the incoming air, thus achieving neutral behavior.

[0014] In a further embodiment, it is also advantageous if the second spoiler blade is pushed out from beneath the first spoiler blade in the second extended state, essentially in a longitudinal direction. The pushing out does not necessarily occur along a straight path, but can also occur along a curved path or by pivoting in the direction of displacement. This achieves efficient displacement of the second spoiler blade to reach a position behind the first spoiler blade, resulting in a virtually extended overall spoiler blade as a successively arranged, adjacent arrangement of the two spoiler blades.

[0015] It is also expedient if the first spoiler blade is pivoted substantially about a pivot axis into the second extended state and / or if the first spoiler blade is pivoted further substantially about the pivot axis into the third extended state. In this case, the pivoting need not necessarily occur about a rotational axis, but can also occur along a path such that the first spoiler blade is raised in a pivoted manner. In this case, the rear part of the first spoiler blade is raised, or raised more strongly, than the front part of the first spoiler blade.

[0016] In these documents, "front" means the front of a motor vehicle in the direction of travel, i.e., toward the front, and "rear" means the rear of a motor vehicle in the direction of travel, i.e., toward the rear. Also, "top" means vertically upwards, and "bottom" means vertically downwards.

[0017] In a further embodiment, it is also expedient if the first spoiler blade is arranged sloping from front to rear in the first retracted state, and / or the first spoiler blade and the second spoiler blade are each arranged sloping from front to rear in the second extended state, and / or the first spoiler blade is arranged sloping from front to rear in the third extended state. This allows the different states to be assigned to different flow effects.

[0018] It is also expedient if at least one actuator is provided that drives the displacement of the first spoiler blade and the second spoiler blade, or if at least two actuators are provided, with at least one first actuator driving the displacement of the first spoiler blade and at least one second actuator driving the displacement of the second spoiler blade. In this case, one actuator can be arranged on each side of the spoiler arrangement, or two actuators can be provided on each side of the spoiler arrangement.

[0019] In a further embodiment, it is expedient if the at least one actuator is coupled to the first spoiler blade and to the second spoiler blade by means of a mechanical coupling in such a way that it drives the first spoiler blade and the second spoiler blade, or if the at least one first actuator is coupled to the first spoiler blade by means of a mechanical coupling in such a way that it drives the first spoiler blade, and if the at least one second actuator is coupled to the second spoiler blade by means of a mechanical coupling in such a way that it drives the second spoiler blade.

[0020] It is particularly advantageous if the mechanical coupling is a gear coupling, multi-joint kinematics, or similar. This allows for efficient movement of the spoiler blades.

[0021] The problem of the motor vehicle is solved with the features of claim 10.

[0022] One embodiment of the invention relates to a motor vehicle having a motor vehicle body with a roof, a rear end, a tailgate, and / or a trunk lid, wherein a spoiler arrangement according to the invention is arranged on the roof, the rear end, the tailgate, and / or the trunk lid. As a result, a spoiler arrangement is arranged on the rear end that can implement the various desired states mentioned above and is designed efficiently and requires minimal installation space.

[0023] The invention will be explained in detail below using an exemplary embodiment with reference to the drawings. In the drawings: Fig. 1 is a schematic sectional view of an embodiment of a rear end of a motor vehicle with a spoiler arrangement in a first retracted state, Fig. 2 a schematic perspective view of the rear of a motor vehicle according to Fig. 1 with the spoiler arrangement in a first retracted state, Fig. 3 is a schematic sectional view of an embodiment of a rear end of a motor vehicle with a spoiler arrangement in a second extended state, Fig. 4 a schematic perspective view of the rear of a motor vehicle according to Fig. 3 with the spoiler arrangement in a second extended state, Fig. 5 is a schematic sectional view of an embodiment of a rear end of a motor vehicle with a spoiler arrangement in a third extended state, and Fig. 6 a schematic perspective view of the rear of a motor vehicle according to Fig. 5 with the spoiler arrangement in a third extended state.

[0024] The Fig. 1, Fig. 3 and Fig. 5 each show a spoiler arrangement 1 in different states in section and the Fig. 2, Fig. 4 and Fig. 6 show a rear end 2 of a motor vehicle 3 with a corresponding spoiler arrangement 1 according to the Fig. 1, Fig. 3 and Fig. 5 in the respective states. The Fig. 1 and Fig. 2 show the spoiler arrangement 1 in a first retracted state, the Fig. 3 and Fig. 4 show the spoiler arrangement 1 in a second extended state and the Fig. 5 and Fig. 6 show the spoiler arrangement 1 in a third extended state.

[0025] The spoiler arrangement 1 according to the Fig. 1 to 6 is advantageously arranged on a rear end 2 of a motor vehicle 3. In principle, the spoiler arrangement 1 can also be arranged differently. It is particularly advantageous if the motor vehicle 3 is configured with a motor vehicle body 6, a roof 7, and a rear end 2.

[0026] A tailgate 8 can be provided at the rear 2, as shown in the Fig. 1 to 6. Alternatively, a trunk lid can also be provided. In this case, it is generally also advantageous if the spoiler arrangement 1 is arranged on the roof 7 or directly on the rear 2, on the tailgate 8, and / or on the trunk lid.

[0027] According to the Fig. 1 to 6, the spoiler assembly 1 comprises a first spoiler blade 4 and a second spoiler blade 5. The first spoiler blade 4 is arranged to be displaceable, and the second spoiler blade 5 is also arranged to be displaceable.

[0028] To move the first spoiler blade 4 and the second spoiler blade 5, at least one actuator 9, 10 is provided, which drives the movement of the first spoiler blade 4 and the second spoiler blade 5, or at least two actuators 9, 10 are provided, such that at least one first actuator 9 drives the movement of the first spoiler blade 4 and at least one second actuator 10 drives the movement of the second spoiler blade 5. The figures schematically show that at least two actuators 9, 10 are arranged, at least one actuator 9, 10 for each spoiler blade 4, 5. It is also possible for two actuators 9, 10 to be provided per spoiler blade 4, 5, for example, one actuator 9, 10 for each spoiler blade 4, 5 on each side of the spoiler blade 4, 5, viewed in the width direction.

[0029] In this case, the at least one actuator 9, 10 can be coupled to the first spoiler blade 4 and to the second spoiler blade 5 by means of a mechanical coupling 11, 12 in such a way that it drives the first spoiler blade 4 and the second spoiler blade 5, or the at least one first actuator 9 is coupled to the first spoiler blade 4 by means of a mechanical coupling 11 in such a way that it drives the first spoiler blade 4, and the at least one second actuator 10 is coupled to the second spoiler blade 5 by means of a mechanical coupling 12 in such a way that it drives the second spoiler blade 5, as shown in the figures.

[0030] The mechanical coupling 11, 12 can be a gear coupling, a multi-joint kinematics or similar.

[0031] The displacement of the two spoiler blades 4, 5 is such that the first spoiler blade 4 and the second spoiler blade 5 are in a first retracted state, see Fig. 1 and Fig. 2, in a second extended state, see Fig. 3 and Fig. 4, and in a third extended state, see Fig. 5 and Fig. 6, are adjustable. The spoiler blades 4, 5 can also be adjusted to intermediate states, which can be passed through to reach the three aforementioned states.

[0032] In the first retracted state, the first spoiler blade 4 and the second spoiler blade 5 are each arranged one above the other in a retracted position such that the first spoiler blade 4 covers the second spoiler blade 5, see the Fig. 1 and Fig. 2. In this first state, air essentially flows over only the first spoiler blade 4, and the second spoiler blade 5 is arranged hidden beneath the first spoiler blade 4 in a receptacle 13. In the first retracted state, the first spoiler blade 4 is arranged such that it essentially follows the contour of the rear 2 of the motor vehicle 3. The first spoiler blade 4 is arranged sloping backwards, i.e., sloping from front to rear. In this first state, neutral behavior is achieved; the first retracted state is a resting state of the spoiler arrangement 1, in which both spoiler blades 4, 5 are retracted.

[0033] Furthermore, the first spoiler blade 4 and the second spoiler blade 5 are in the second extended state according to the Fig. 3 and Fig. 4 are each arranged in an extended position, wherein the first spoiler blade 4 is raised into a first raised position and the second spoiler blade 5 is extended such that it is arranged in the extension of the first spoiler blade 4 behind the first spoiler blade 4. The first spoiler blade 4 is pivoted into the second extended state essentially about a pivot axis. The second spoiler blade 5 is pushed out into the second extended state essentially in a longitudinal direction under the first spoiler blade 4. As a result, the first spoiler blade 4 and the second spoiler blade 5 form a common enlarged spoiler blade 4, 5, which is extended in the vehicle longitudinal direction, in particular doubled. Fig. 3, this quasi-common spoiler blade 4, 5 is arranged sloping rearward, since the first spoiler blade 4 and the second spoiler blade 5 are each arranged sloping from front to rear in the second extended state. The second extended state is an efficient state in which air resistance is reduced by the two spoiler blades 4, 5 forming an extended, sloping spoiler blade 4, 5 toward the rear.

[0034] Furthermore, the first spoiler blade 4 and the second spoiler blade 5 are arranged one above the other in the third extended state such that the first spoiler blade 4 is arranged in a second raised position and the second spoiler blade 5 is arranged substantially in its retracted position below the first spoiler blade 4, see Fig.5. The first spoiler blade 4 is pivoted further rearward and upward about the pivot axis into the third extended state. In this third state, air essentially flows over only the first spoiler blade 4, and the second spoiler blade 5 is arranged essentially hidden beneath the first spoiler blade 4 in the mount 13. The first spoiler blade 4 is arranged so that it rises from front to rear. In this third state, the downforce provided by the first spoiler blade 4 is increased or improved; the third extended state is a performance state.
