technical field

The invention relates to an outlet device, in particular for a motor vehicle, having a housing with at least one flow channel; a plurality of air guide vanes assigned to the outlet-side end of the flow channel; A flap in the channel and deflectable about a first axis; an actuating element assigned to the outlet-side end of the flow channel for deflecting the flap and a lever drive connecting the actuating element to the flap, the actuating element Pivotable about a second axis, wherein the first axis and the second axis are aligned at least substantially perpendicularly to one another, the lever drive has at least one lever which is pivotably mounted on the housing.

Background technique

Outlet devices of the type mentioned at the outset are already known from the prior art. The outlet device is used in motor vehicles to provide the user with a comfortable interior climate with comfortable outflow characteristics. In this case, the outlet-side end of the flow channel with the outlet is assigned to the vehicle interior, wherein conventional air guide vanes can be deflected by the user at the outlet-side end of the flow channel in order to be able to change the flow from The outflow direction of the air flow coming out of the channel. In order to regulate the volume flow of the air flow through the flow channel, it is also known to provide a deflectable flap in the flow channel which, depending on the swivel position, completely closes or partially or completely opens the flow channel. Since the flap is located upstream in the flow channel separated from the air flow of the outlet, a mechanism is required by means of which the user can actuate the flap located behind in the flow channel from his perspective. Different solutions have been known for this purpose.

Thus, for example, laid-open document DE 10 2008 018 762 A1 discloses an outlet device with an actuating element assigned to the outflow-side end of the flow channel, which is connected via a bevel gear with a deflectable flap. connect. However, the provision of bevel gears for force transmission has the disadvantage that the mechanical connection between the actuating element and the flap is playful. In particular, when the user changes the actuating direction or the direction of rotation of the operating element, he must first overcome the play of the gear train before he can pivot the flap in the opposite direction.

An outlet device having an actuating element and a flap connected to one another via a lever drive is known, for example, from laid-open document DE 10 2009 051 297 A1. In this case, however, the axes of the actuating element and of the flap are parallel to one another, which may not be desirable depending on the available installation space and the application.

Said prior art is disclosed in laid-open document EP 1 288 034 A1. An outlet device is disclosed there, in which the actuating element is connected to the flap via a lever drive, wherein the actuating element and the axes about which the flap pivots lie perpendicular to each other. In this case, the lever transmission includes a deflection hook mounted on the housing so that it can pivot. The diverting hook is mounted centrally and has a tenon/fork connection at its free ends, via which it is connected to the actuating element or to the flap. Through the tenon/fork connection, the pivoting movement of the actuating element is converted into a pivoting movement of the flap in a simple manner. However, this tenon/fork connection has the disadvantage that it only enables a slotted actuation of the flap. Due to the sliding of the tenon in the fork or in the elongated hole for the actuation, there is an unavoidable play when the flap is actuated, in particular when reversing the actuating direction.

Contents of the invention

It is therefore the object of the present invention to provide an outlet device in which the axes of the actuating element and of the flap are aligned at least substantially perpendicularly to one another, wherein the actuation of the flap takes place at least largely without play by the actuating element.

The object underlying the invention is achieved by an outlet device having the features of claim 1 . This has the advantage that an at least essentially play-free operation is ensured when using the lever drive to positively connect the actuating element and the flap, which ensures precise actuation of the flap and also contributes to a high-quality feel for the user during operation.

The object of the invention is achieved in that the lever drive according to the invention has a coupling point configured without play in the actuating direction, and the lever has at least one coupling and/or bearing point which can be elastically The ground moves out of the swing plane of the lever. The seamless configuration of the coupling point in the actuating direction firstly allows direct actuation of the flap by the actuating element. The elastic release of the at least one coupling and/or bearing point allows the lever drive to be operated without straining or clamping the lever drive. Since the first axis and the second axis are aligned at least substantially perpendicularly to one another, the lever drive must be able to permit a pivoting movement in several directions. This is achieved in the mentioned publication EP 1 288 034 A1 by a tenon/fork connection, which allows a height deviation between the interacting elements during deflection. Due to the elastic movement of the bearing point according to the invention out of the pivot plane of the lever, the above-described height offset between the mutually coupled elements is ensured when the lever drive is deflected. The elastically movable bearing points and/or coupling points thus replace the tenon/fork connection and allow height deviations during deflection and ensure a gap-free coupling or mounting in the actuating direction. The fact that the coupling point can in particular be elastically moved out of the pivot plane of the lever also enables the coupling point to remain or be able to remain in the pivot plane of the lever when the lever itself is at least partially moved out of the pivot plane, for example during elastic bending. middle.

It is preferably provided here that the lever is at least partially elastically deformable. The elastic displaceability of the coupling and/or bearing point is thereby made available in a simple and cost-effective manner. Thus, for example, the elastic deformability of the lever enables it to be pivotably supported at one end and to be elastically movable out of a deflection plane perpendicular to the pivot axis of the support at the other end by the method described The lever is elastically bent along its longitudinal extension. The elastically deformable design makes it possible in particular to dispense with additional elements, such as in particular spring elements or the like, resulting in a particularly simple and cost-effective construction of the lever drive.

Furthermore, it is preferably provided that the lever is mounted at one end on the housing so as to be pivotable about a third axis and is connected at the other end via a coupling point to a pivot lever which is fixedly connected to the flap. The lever is thus mounted or coupled at one end to the housing and at the other end to the pivot lever. As a result, the lever has the advantage of the largest possible lever length with respect to the available installation space, which is advantageous in particular when the lever is constructed elastically.

The longer the lever, the farther it can be pivoted out of the pivot plane of the lever by elastic deformability. The farther the bearing point and/or the coupling point can be elastically moved out of the pivot plane of the lever, the larger the pivot lever connected to the flap can be designed. In this way, the lever drive can be further optimized for the respective application. The lever drive is arranged on the housing, in particular outside the flow channel, wherein the actuating element is also located on the housing, in particular outside the flow channel, wherein the actuating element is advantageously arranged in a manner accessible to the user. Next to the air guide vanes.

Furthermore, it is preferably provided that the third axis is oriented parallel to the second axis. The lever is thus pivotable about an axis parallel to the pivot or rotation axis of the actuating element. As a result, the lever can be directly applied with an actuating force by the actuating element, so that force losses are minimized. Furthermore, the lever can thus also be pivoted in a pivot plane, which is oriented parallel to the first axis. In particular, the pivot lever connected to the shutter lies in a plane perpendicular to the first axis, so that the pivot lever can be pivoted in a plane at least substantially perpendicular to the pivot plane of the lever.

According to a preferred development of the invention it is provided that the coupling point connecting the lever to the swivel lever is a seamless ball joint. This ball joint ensures that the pivot lever and the lever do not clamp against one another during the deflection when the ball joint is withdrawn from the pivot plane of the lever by deflecting the pivot lever. The previously described elastic configuration of the coupling and/or bearing point of the lever ensures that it can follow the movement of the pivot lever without straining the lever drive.

Furthermore, it is preferably provided that the lever drive has a coupling lever which is connected on one side to the actuating element and on the other side to the lever via a coupling point in an articulated manner. The coupling lever thus constitutes the functional connection between the operating element and the lever. This ensures a direct and simple force transmission. By pivoting the actuating element and the lever about parallel axes, the coupling lever is acted upon along its longitudinal extension to be either stretched or compressed when the actuating element is actuated.

According to a preferred development of the invention it is provided that the lever has a pin receptacle in which a pin of the coupling lever is rotatably seated in order to form the coupling point. That is, the coupling point between the lever and the coupling lever is ensured by a pin connection, which ultimately constitutes a rotary joint. This provides a simple and reliable coupling point.

Furthermore, provision is preferably made for the bolt receptacle to be formed as a ring element which is situated in particular in an opening of the lever, wherein the ring element is connected to the lever via an elastically deformable web, so that the ring element can rest on the web. Elastically deformed, it moves out of the pivot plane of the lever. The lever thus has a ring element which is connected to the lever via an elastically deformable web. In particular, it is provided that the ring element is located in the opening in the plane of the lever. Via the elastically deformable web, the ring element can easily be moved out of the plane of the lever so that it protrudes out of the opening, for example in the direction of the lever. The elastic web thus ensures elastic deformability of the coupling point with a minimum of space. As a result, when the lever drive is deflected, the lever can, for example, be removed from the pivot plane at its end facing the pivot lever, while the coupling point remains in the pivot plane due to the elastic deformation of the web and thus prevents the lever on the one hand. The tightening of the transmission and on the other hand ensures play-free operation.

Furthermore, it is preferably provided that the pin has a pin head which is designed to be larger than the clear width of the ring element, wherein the ring element is designed as a grooved ring for receiving the pin. As a result, the pin can be introduced in a simple manner by expanding the grooved ring, for example until the pin head has penetrated the ring element in the axial direction. In particular, the ring element itself is likewise designed to be elastically deformable, so that once the bolt head has passed the grooved ring, the ring element closes again in order to ensure a seamless support of the bolt in the actuating direction. By setting the bolt head, it is realized that the coupling lever will not be easily loosened from the lever. In particular, it is provided that the height of the ring element corresponds to the distance between the bolt head and the coupling rod, so that the ring element is held between the bolt head and the coupling rod without any play in the axial direction of the bolt, or instead firmly held between the head of the bolt and the axial stop of the bolt. This makes it possible to compensate the pivoting movement of the pivot lever out of the plane of the lever when the lever drive is deflected only by elastic deformation and not by pushing the two elements relative to each other, so that there is always a clear definition of the elements of the lever drive. of mutual cooperation.

The web advantageously extends between the ring element and the lever in the actuating direction or in the direction of the coupling lever or in the direction of the longitudinal extension of the coupling lever. This achieves that when the coupling lever is loaded in tension or compression by the deflection of the actuating element, the tension or compression force is directly transmitted to the lever in that the web is at least substantially only loaded in tension or compression tight. This ensures a direct force transmission which in particular avoids an elastic deformation of the web due to the deflection of the actuating element, which would not be caused by the movement of the pivot lever. A reliable, seamless and direct operation of the outlet device is thus ensured for the user in a simple and cost-effective manner.

The invention shall be explained in more detail below on the basis of examples. Shown for this:

Figure 1 is a top view of an exit device for a motor vehicle,

Figure 2 is a perspective bottom view of the outlet device, and

detailed description

FIG. 1 shows a top view of an outlet device 1 , which is designed as a double outlet. The outlet device 1 has a housing 2 which has two flow channels 3 , 4 arranged next to one another, which each have a cross-section that differs from a circle. The flow channels 3 , 4 run parallel to one another and are substantially identical, the flow channel 4 now having a smaller cross section than the flow channel 3 . Each of the flow channels 3 , 4 is associated here with an outlet 5 or 6 of the outlet device 1 . In this case, the outlets 5 , 6 are substantially identical to one another, so that in order to explain the outlets 5 and 6 below, only the outlet 5 should be considered first.

At the end 7 of the flow channel 3 , which is assigned to the interior of the motor vehicle with the outlet device 1 , that is to say on the outlet side, the outlet 5 has a plurality of at least substantially horizontally extending air guide fins 8 , which air guide The sheets can each be deflected at the housing 2 about a horizontal axis. Furthermore, the outlet 5 has a plurality of air guide vanes 9 arranged perpendicularly to the air guide vanes 8 , which are held on the housing 2 so that they can each be pivoted about a vertical axis and each have a cross-section of the flow channel 3 . Extend up. In this case, the air guide flaps 9 and 8 are actuated by the user via a common operating element 10 in order to deflect the (air) flow from the flow channel 3 in a desired direction into the vehicle interior.

As can be further drawn from FIG. 1 , from the perspective of the user, in the flow channel 3 behind the air guide plates 8 , 9 , ie upstream of the air flow, a valve 11 is also arranged, which can surround the first An axis 12 is pivotally mounted so that the flow channel 3 is opened, as shown in FIG. 1 , completely closed or partially closed or opened. The axis 12 here runs parallel to the air guide vane 8 or horizontally through the flow channel 3 . The terms “horizontal” and “vertical” in the case of the exemplary embodiment refer to the diagram of FIG. 1 in each case. Of course, the outlet arrangement shown there can be arranged on the motor vehicle in different orientations and positions, so that in the assembled state the air guide vanes 8 run, for example, horizontally or vertically or also in an oblique arrangement.

To actuate the flap 11 , a further actuating element 13 is assigned to the outlet 5 , which is designed as an adjusting wheel and is mounted so as to be pivotable about an axis 14 . In this case, the actuating element 13 is assigned to the outlet-side end 7 of the flow channel 3 in such a way that it is held on the housing 2 below the flow channel 3 so that it can be reached by the user. In this case, the axis 14 is now oriented almost perpendicularly to the axis 12 of the flap 11 . By rotating the adjusting wheel or operating element 13 about the axis 14 , that is to say from left to right or from right to left in the drawing plane of FIG. 1 , the flap 11 is as shown in FIG. 1 . It is deflected about axis 12 into its closed position or into its open position.

To transmit the actuating force, the outlet device 1 has a lever drive 15 associated with the outlet 5 , which is covered by the housing 2 in FIG. 1 .

FIG. 2 shows the outlet device 1 in a perspective view looking at the bottom side of the housing 2 . Elements already known from FIG. 1 are provided with the same reference numerals, so that in this respect reference is made to the above description. In FIG. 2 , the lever drive 15 can now be seen, which connects the actuating element 13 to the flap 11 . In this case, the lever drive 15 is constructed in multiple parts. It has a lever 16 , one end 17 of which is pivotally mounted on the housing 2 at the bearing point L1 , and the other end 18 of which is connected via a ball joint 19 to the pivoting lever at the coupling point K1 . 20, which is fixedly connected to the shutter 11. In this case, the pivot lever 20 is pivotably oriented in a plane perpendicular to the axis 12 and is located outside the housing 2 , wherein together with the end 18 of the lever 16 it forms the free end 21 of the ball joint 19 and the joint. The axis 12 is spaced so far apart that it protrudes beyond the bottom side of the housing 2 in the pivot range required for pivoting the flap 11 . The ball joint 19 is designed without play, so that a movement of the lever 16 causes a movement of the pivot lever 20 and thus the flap 11 at least substantially without play. In this respect, the coupling point K1 formed by the ball joint 19 is thus formed seamless in the actuating direction. Furthermore, the lever 16 has a grooved ball seat 22 on its end 18 which is designed to receive the ball head 23 of the pivot lever 20 without play, in particular prestressed, so that the ball seat 22 is prestressed. This ball head 23 is accommodated and seamlessness is thereby ensured.

The lever 16 has a cylindrical opening 24 at its end 17 for the bearing point L1 , which is inserted into a slotted cylinder 25 protruding from the housing 2 . The slotted cylinder 25 has a housing section 26 with a radially outwardly projecting detent web which can be displaced radially inwardly by elastic deformation. By inserting the lever 16 onto the cylinder 25 said latching ledge is moved inwards and brought into its initial position due to its own elasticity, once the lever 16 has reached its final position, the latching ledge 26 is locked in the opening 24 The lever 16 is blocked on the edge side, so that it is held firmly and positively on the housing 2 . The slotted sleeve 25 can optionally also have a plurality of such latching webs 26 . The inner diameter of the opening 24 and the outer diameter of the cylinder 25 correspond at least substantially to one another, so that an at least essentially play-free mounting of the lever 16 on the housing 2 is provided via the bearing point L1 . The lever 16 and the sleeve 15 thus jointly form a bearing point L1 for the lever 16 , which forms a swivel or pivot bearing 27 .

The lever 16 is connected to the operating element 13 via a coupling rod 28 . Furthermore, the coupling lever 28 is fastened eccentrically at one end to the actuating element 13 in the actuating direction by means of a pivot bearing. At the other end, the coupling lever 28 is connected to the lever 16 via a coupling point K2.

For this purpose, FIG. 3 shows the coupling point K2 in a simplified illustration. FIG. 3A shows the coupling point K2 in an enlarged plan view and FIG. 3B shows the coupling point K2 in a sectional view.

As can be seen from FIG. 3A , the lever 16 has a circular opening 30 at the coupling point K2 . In this opening 30 , the ring element 31 lies in the plane of the lever 16 and is connected to the lever 16 on one side via a web 32 . In particular, it is provided that the web 32 is formed in one piece with the ring element 31 and with the lever 16 . The ring element 31 is designed as a grooved ring, so that the clear width of the ring element 31 can be changed elastically by expanding the ring. The ring element 31 here forms the pin receptacle 29 of the coupling point K2.

3B shows in a sectional view that the coupling lever 28 has a pin 33 at its end facing the lever 16, which pin is configured on the end side with a pin head 34 whose diameter is greater than that of the ring element 31 in the initial state. net width. For assembly, the pin head 34 is pushed into it with the ring element 31 widened until the ring element 31 snaps back due to its own elasticity after overcoming the pin head 34 and thus axially from behind The pin head 34 is clamped. As can also be seen in FIG. 3B , the pin 33 has an axial stop 35 spaced apart from the pin head 34 , which is preferably spaced apart from the pin head 34 in such a way that the ring element 31 is at least It is held essentially without play between the bolt head 34 and the stop 35 . The lever 16 is generally elastically configured to be deformable.

When the user actuates the operating element 13 , for example according to the arrow 36 in FIG. 2 , a pressing force is introduced at the coupling point K2 onto the lever 16 by means of the coupling lever 28 . The web 32 of the coupling point K2 is oriented in the direction of the coupling lever 28 , so that the pressing force is transmitted directly to the lever 16 in the pivot plane of the lever 16 . The lever 16 is thus pivoted about the bearing point L1 according to the arrow 37 . This causes the pivot lever 20 , which is fixedly connected to the flap 11 , to also move via the coupling point K1 , as indicated by the arrow 38 in FIG. 2 . Due to the movement of the free end of the pivoting lever 20 on a circular path, the lever 16 is moved at its free end 18 out of a deflection plane of the lever 16 perpendicular to the axis 39 , which passes through the bearing point L1 limited. This movement is achieved by the elasticity of the lever 16 without tensioning the lever drive 15 . The coupling point K2 is advantageously configured such that the bearing point 29 itself remains on the lever 16 due to the elastic deformability of the web 32 when the lever 16 moves with the free end 18 out of the pivot plane. in the swing plane. The ring element 31 thus adapts elastically to the respective situation and ensures a seamless force transmission even when the direction of actuation of the actuating element 13 changes, so that a reliable and unambiguous actuation of the flap 11 is always ensured.

As already mentioned above, the outlet 6 is constructed almost identically to the outlet 5 , so that the outlet 6 also includes a corresponding flap 11 , a corresponding operating element 13 and a corresponding lever drive 15 . As can be seen from FIG. 2 , the outlets 5 , 6 are only designed as mirror images with respect to the lever drive 15 .

In order to reduce the number of parts, in particular the pivot lever 20 , the coupling lever 28 and the actuating element 13 of the two outlets 5 , 6 are designed identically. This is now achieved in that the lever 16 is correspondingly configured with two coupling locations K2, which are arranged spaced apart from each other on the lever 16, so that, depending on which location the lever 16 is provided, it is possible as before As described, the coupling rod 28 is operatively connected to one or the other of the coupling points K2. In order to avoid incorrect assembly, it is preferably provided that approximately semicircular segment-shaped webs 40 are assigned to the coupling points K2 , which only allow a definite assembly of the coupling lever 28 with respect to the lever 16 .

The advantageous outlet device 1 thus realizes the actuation of the flap 11 in the respective flow channel 3 , 4 by means of an operating element 13 whose rotation or pivot axis 14 is perpendicular to the pivot axis 12 of the flap 11 , wherein the lever drive The device 15 ensures a gap-free functional connection between the respective operating element 13 and the associated flap 11 in a simple and cost-effective manner.
