H. at least two, air passage openings and a pivotal flap mounted on a support structure, the between a closed position in which an air passage through the air passage openings minimal, d. H. For example, is prevented, and an open position in which an air passage through the air passage openings is maximum, is pivotable, wherein the one hinged flap in the closed position, the plurality, d. H. at least the two, air passage openings closes.

Description

  • The present invention relates to an air supply adjusting device for a motor vehicle having a plurality of air passage openings and a pivotable flap for adjusting an air passage through the air passage openings.
  • It is known to provide for controlling an air supply to a radiator of a motor vehicle rotatable or adjustable flaps, by means of which an amount of air can be adjusted, which is supplied to the radiator. By way of example, such an air supply adjusting device is arranged in the region of a so-called radiator grille, that is to say behind a radiator grille or in the radiator grille. In the case of closed flaps, an air resistance of the motor vehicle and thus a fuel consumption of the motor vehicle can advantageously be reduced. Another advantage is that heat loss of the engine compartment can be kept low when needed with the door closed. If a higher cooling capacity is required, which is not achievable with the flaps closed, the flaps will open.
  • From the DE 10 2008 049 228 A1 For example, a grille assembly is known which has a radiator grille having horizontal webs, between which air passage openings are formed. In each air passage opening a rotatable about a rotation axis flap is formed, which can open or close the respective air passage opening.
  • Furthermore, in the DE 10 2014 108 575 A1 described as radiator shutter rotatable flaps, wherein three flaps are arranged in an air passage opening and the three flaps can close the air passage opening.
  • Accordingly, from the prior art Luftzufuhreinstellvorrichtungen are known in which either one flap can close an air passage opening, wherein at several air passage openings each air passage opening is associated with a flap, or more flaps can close an air passage opening.
  • It is the object of the present invention to provide an air supply adjusting device for a motor vehicle and a motor vehicle with such an air supply adjusting device, which has a reduced number of components and in particular fewer moving components.
  • This object is achieved by an air supply adjusting device for a motor vehicle having the features of claim 1. Furthermore, this object is achieved by a motor vehicle with such a Luftzufuhreinstellvorrichtung. Preferred embodiments of the invention are mentioned in the dependent claims.
  • According to the present invention, an air supply adjusting device for a motor vehicle has a plurality, i. H. at least two, air passage openings and a pivotal flap mounted on a support structure, the between a closed position in which an air passage through the air passage openings minimal, d. H. For example, is prevented, and an open position in which an air passage through the air passage openings is maximum, is pivotable, wherein the one hinged flap in the closed position, the plurality, d. H. at least the two, air passage openings closes.
  • Accordingly, the plurality of air passage openings are closable only with a single flap, so that only a flap and therefore only a pivoting mechanism is required for this purpose, whereby a number of particular moving components of the Luftzufuhreinstellvorrichtung is reduced. Thus, the structure of the Luftzufuhreinstellvorrichtungen invention over known from the prior art Luftzufuhreinstellvorrichtung with multiple flaps and associated multi-joint mechanisms is easier.
  • The one hinged flap can, for example, also close three, four, five, six, seven, eight, nine, ten or more air passage openings.
  • According to a preferred embodiment of the present invention, the Luftzufuhreinstellvorrichtung is located directly behind a radiator grille of the motor vehicle or is part of the radiator grille of the motor vehicle.
  • An arrangement within the grille or immediately behind the grille increases aerodynamic effect, i. H. a reduction of air resistance of the motor vehicle, the Luftzufuhreinstellvorrichtung with the flap closed.
  • Preferably, the plurality of air passage openings are formed by the grille.
  • For example, the grille may include a frame member having at least one land disposed within the frame member, thereby forming the plurality of air passage openings. In other words, the web divides the interior of the frame element into at least two areas, which form at least two air passage openings.
  • It can also be arranged more than one ridge within the frame member. The web or webs can / may for example run vertically and / or horizontally. But it is also possible any other course of the web or the webs.
  • Hereby forms the frame member together with the webs a plurality of through holes, which are all closed by a pivotable flap.
  • In this case, according to the invention, the pivotable flap can be designed such that it rests in the closed position on the frame element and the web or webs. In addition, in the closed position, the flap may be sealingly attached to the frame element. Furthermore, in the closed position, the flap may be sealingly attached to the web or webs.
  • Due to the sealing engagement of the flap on the frame element and optionally in addition to the webs, air resistance of the motor vehicle is reduced and disturbing wind noise is also reduced. An air passage through the air passage openings is prevented in particular by the sealing engagement of the flap on the frame element.
  • According to a preferred embodiment of the present invention, in the Luftzufuhreinstellvorrichtung the pivotable flap is pivotally mounted via a multi-joint mechanism.
  • Due to the inventive mounting of the pivotable flap on the multi-joint mechanism, a movement path of the flap can be adapted to an available space and to a geometry of the flap or to be closed by the flap opening. Accordingly, it is possible by a multi-joint mechanism, that the flap performs a pivoting movement without the flap moves on a merely circular trajectory, which is not possible depending on the space and geometry of the flap. Thus, it may be possible despite limited space that use a large flap instead of many small flaps.
  • Preferably, the multi-joint mechanism is a four-bar mechanism.
  • With a four-bar mechanism, a movement path of the flap can be defined particularly easily. In particular, the four-bar linkage is designed in the manner of a linkage.
  • Through the four-bar linkage or the coupling gear, the flap can be mounted purely on swivel joints, which allow a trajectory, the four-bar relative to contamination is much less sensitive than, for example, a pivot mechanism, which is realized via a slotted guide. Joints can maintain their function permanently and for a long period without maintenance.
  • According to a preferred embodiment, the four-bar mechanism has a first link, which is articulated via a first carrier-structure-side joint and a first flap-side joint, and a second link, which is articulated via a second carrier-structure-side joint and a second flap-side joint.
  • Each joint allows each pivoting of the arm about a respective axis of rotation, wherein the axes of rotation are all formed substantially parallel to each other.
  • In this arrangement, the flap forms a coupling between the first link and the second link, which are in turn mounted stationary support structure side. Thus, the corresponding kinematics overall results in a coupling gear.
  • Preferably, the multi-link mechanism, which in particular has the four-bar linkage with, for example, the first link and the second link, is arranged laterally of the pivotable flap.
  • A lateral arrangement of the multi-joint mechanism, in particular of the four-bar linkage with the two links, is advantageous with regard to an unobstructed passage of air through the air passage opening. Further, the handlebars in a lateral arrangement against environmental influences, in particular against pollution and corrosion, can be arranged protected, so that a lifetime and function of the Luftzufuhreinstellvorrichtung are improved.
  • For more stable storage of the flap, the multi-joint mechanism can also be arranged substantially symmetrically to the left and right of the flap. As a result, a reliability of the function of the air supply setting is increased, it disadvantageous torques are avoided and it can prevent tilting of the flap.
  • According to a preferred development of the four-bar mechanism with the first and the second link, the first and the second link are arranged such that they intersect.
  • This arrangement allows a particularly compact design of the multi-joint mechanism and a particularly stable storage of the flap. In particular, the crossed arrangement of the handlebar allows a trajectory with very small radii, which is advantageous in terms of a limited space.
  • According to a preferred embodiment of the Luftzufuhreinstellvorrichtung with the first link and the second link, the first link is driven via a rotation axis of the carrier structure-side joint by means of a drive. Alternatively or additionally, the second link may be driven via a rotation axis of the carrier-structure-side joint by means of a drive.
  • An advantage of the four-bar linkage mechanism here is that only one link must be driven via its carrier structure-side joint with a rotating drive.
  • Preferably, an outer surface of the flap is curved or arched in a transverse direction and / or in a vertical direction. In other words, the outer surface of the flap can be performed cambered. The external surface of the flap designates the surface which faces an air flow. The outer surface can also be referred to as a closure surface.
  • The combination of a one-way or more-curved flap with a multi-link mechanism bearing is particularly advantageous because the curved outer surface is easily engageable with a sealing frame via the path of travel of the multi-link mechanism in the closed position.
  • The above-mentioned further features of the invention can be combined as far as possible and meaningful with each other.

  • The following is a detailed description of an embodiment with reference to FIG 1 to 5 ,
  • As in 1 and 2 has an air supply adjusting device 1 for a motor vehicle a flap 5 , the air vents 3 can close. The air vents 3 are formed in a radiator grille of the motor vehicle and serve a cooling air supply to a heat exchanger of the motor vehicle. The heat exchanger may be a radiator for cooling a cooling liquid for an internal combustion engine. The heat exchanger may also be part of a cooling circuit of an interior climate. The grille is through a frame element 13 as well as several vertical struts 15 formed between which the air passage openings 3 are formed. In a closed position of the flap 5 , in the 1 shown is the flap 5 on an inner side of the frame element 13 as well as on insides of the struts 15 at. The inner side is the side which faces away from an air flow. Thus, in the closed position, all air passage openings 3 through the only hinged flap 5 closed, with an air passage is prevented. This is for all air vents 3 also only a pivot mechanism required. In a fully open position of the flap 5 , in the 2 is shown, are the air passage openings 3 passing through the frame element 13 and the vertical struts 15 are limited, completely free. The flap 5 may also assume intermediate positions between the open position and the closed position, which allow a correspondingly limited passage of air through the air passage openings.
  • The flap 5 is mounted on a four-bar linkage, which is a multi-joint mechanism according to the invention. In particular, the four-bar linkage has a first link 7 and a second handlebar 9 , The first handlebar 7 is with a fixed joint 71 connected to a support structure, not shown, of the motor vehicle, in particular in 3 to 5 you can see. In particular, the handlebar 7 over the joint 71 pivotable about a fixed horizontal axis of rotation. The second handlebar 9 is also about another carrier structure side joint 91 hinged to the support structure of the motor vehicle. In particular, the second link is 9 around a horizontal axis of rotation of the joint 91 rotatable. Furthermore, the first link 7 via a flap-side joint 72 swiveling at the flap 5 hinged and about a rotation axis of the valve-side joint 72 rotatable. Accordingly, the second link is 9 with a valve-side joint 92 at the flap 5 pivotally hinged and connected to this. This is the second handlebar 9 around a rotation axis of the joint 92 opposite the flap 5 pivotable. This forms the first handlebar 7 , the second handlebar 9 and the flap 5 together with the support structure a coupling gear, wherein the flap 5 a coupling between the first link 7 and the second handlebar 9 represents.
  • In the present embodiment, the first link 7 and the second handlebar 9 arranged crossed. However, it is also possible a non-crossed arrangement arranged. Further, according to the embodiment, the handlebar 7 over the supporting structure-side joint 71 at its axis of rotation with a drive 11 connected. But it can also be alternatively the second link 9 over the axis of rotation of the joint 91 be driven.
  • The flap 5 has a curved in several directions or cambered shape and is in the closed state on the frame member 13 sealingly. The pivoting in the sealing closed position of the domed flap 5 is in particular by the four-bar linkage and the path of movement of the flap thus generated 5 possible.
  • When driving, the flap for cooling air is needed 5 opened by means of the drive and the four-bar mechanism. With sufficient cooling, the flap stays 5 closed for aerodynamic reasons. As in 1 is to be seen, is the flap 5 arranged in the closed state near a vehicle outer skin, so that the aerodynamic effect is sufficiently large. Through the struts 15 is also in the closed state of the flap 5 to see a recognizable as a grille structure, so that an external appearance of the grille with the flap closed 5 and with the door open 5 is similar.
  • In 1 is a frame element 13 with a single flap 5 shown. The motor vehicle may symmetrically have a second frame member with further air passage openings and a Luftzufuhreinstellvorrichtung with another flap as described above. The prong and the right air supply adjusting device can be arranged via a single drive element arranged between the left-hand flap and the right-hand flap 11 be driven. There is also the possibility that the motor vehicle has two adjacently arranged grille openings with two air passages, which can be closed and opened by a single air flap adjusting device with a single flap.
