Description

Air Guiding Device for a Vehicle Front and Method for operating an Air Guiding Device for a Vehicle The invention relates to an air guiding device for a vehicle front according to the preamble of claim 1. Furthermore, the invention relates to a method for operating an air guiding device.

Such an air guiding device can for example already be taken as known from ER 2 233 343 A2. The air guiding device there comprises a plurality of louvers which are arranged in a case. The louvers can be opened for permitting an air flow through the air guiding device and the louvers can be closed for preventing the air flow through the air guiding device. The louvers can be opened and closed by means of an actuator of the air guiding device. In order to open and close the louvers the actuator can be driven in a counter clockwise direction or a clockwise direction, respectively. When the actuator is driven and a main shaft of the actuator rotates in the clockwise direction, a cam rotates in the same direction accordingly. Therefore, a pin, which is arranged at the cam is inserted into a clearance between protruding portions of a swing arm. Further, the cam continuously rotates in the clockwise direction and the pin rotates the swing arm in a fully opening direction of the louvers. In a preferred embodiment of the air guiding device, the actuator drives a second link mechanism, which includes a first and a second link bracket, a base bracket, a spring, a fixing member, the swing arm, a rod, and the like. By means of this air guiding device, the louvers can be opened and closed independently. However, the air guiding device is especially complex and costly due to the usage of a plurality of components. Furthermore, the air guiding device there is comparatively heavy and has increased space requirements.

It is the object of the present invention to provide an air guiding device and a method of the initially mentioned kind, by means of which a fluid flow through the air guiding device can be regulated in an especially space, weight and cost saving manner.

According to the invention, this object is solved by an air guiding device having the features of claim 1 and by a method having the features of claim 5. Advantageous configurations with convenient developments of the invention are specified in the remaining claims.

In order to provide an air guiding device of the initially mentioned kind, by means of which a fluid flow through the air guiding device can be regulated in an especially space, weight and cost saving manner, it is provided according to the invention that the first guiding element and the second guiding element are each designed as guide slots, which are separated from each other and by means of which the first shutter and the second shutter are moveable in dependency on a rotation of the actuator.

In other words by operating the actuator the first shutter and the second shutter can be operated in a sequence, wherein the first shutter and the second shutter can be moved in the opened position and the closed position, respectively, in dependency on the rotation of the actuator. By means of the guide slots (the first guiding element and the second guiding element) the first connecting element and the second connecting element, respectively, can both be moved according to the rotation of the actuator. The guide slots allow a freewheel (in dependency of the rotation of the actuator) of one of the connecting elements, in which this connecting element is at standstill. At standstill the corresponding guide slot (e.g. in the case of the first shutter, the corresponding guide slot is the first guiding element by means of which the first connecting element is guided) is moved according to the rotation of the actuator and thus the guide slot is moved relative to the connecting element. In other words a guiding joint by means of which the connecting element is engaged with the corresponding guide slot, is moved along the guide slot if the connecting element is at standstill and thus there is a freewheel between the guide slot and the corresponding connecting element. During this standstill or freewheel respectively, the other connecting element is moved, since its corresponding guiding joint is in contact with the frame of the other guide slot and the connecting element (and thus the corresponding shutter) is moved according to the rotation of the actuator. Due to the usage of this guide slots, the operation of the first shutter and the second shutter in sequence is achieved in an especially space, weight and cost saving manner.

Further advantages, features and details of the invention are apparent from the following description of a preferred embodiment as well as based on the drawings.

Fig. 1 shows a schematic view of an air guiding device 20 which is arranged at a vehicle front 10 at present. The air guiding device 20 is used to enable and disable a fluid flow 16 (air flow) through the air guiding device 20 towards vehicle components 12, such as e.g. heat exchangers, fans or a combustion engine of the vehicle. The air guiding device 20 comprises a shutter arrangement 28 which is capable of enabling and disabling the fluid flow 16 through the air guiding device 20. The shutter arrangement 28 comprises a first shutter 30 and a second shutter 40, wherein both the first shutter 30 and the second shutter 30 are in a closed position 80 at present. In this closed position 80 shutter elements 26 which are designed e.g. as flaps or louver elements of the first shutter 30 and the second shutter 40, respectively, are also in the closed position 80 in which they disable the fluid flow 16 through the guiding device 20 towards the vehicle components 12. The shutter elements 26 are pivotably connected to a housing element 18 of the air guiding device 20. The shutter elements 26 of both the first shutter 30 and the second shutter 40 can be rotated according to a shutter rotation 22 of the first shutter 30 and the second shutter 40 respectively by means of an actuator 50, which is not shown in Fig. 1.

The shutter rotation 22 is carried out by a rotation of the shutter elements 26 around an x-axis of a coordinate system which is illustrated in Fig. 1. In other words the shutter rotation 22 of the shutter elements 26 is carried out by means of a rotation of the shutter elements 26 in a rotation plane 24, which is defined by a y-axis and a z-axis of the coordinate system. The direction of the y-axis corresponds to a main driving direction of the vehicle (which is not shown here). The z-axis corresponds to a vertical axis of the vehicle, respectively.

With the shutter elements 26 and thus both the first shutter 30 and the second shutter 40 in the closed position 80, the vehicle has a particularly low aerodynamic drag. The following Figs. show, how the shutter elements 26 of the first shutter 30 and additionally or alternatively the second shutter 40 can be moved from the closed position 80 to an opened position 90 and vice versa. In the open position 90 the fluid flow 16 is at least partially enabled through the air guiding device 20 and thus the vehicle components 12 are exposed to the fluid flow 16 at least partially in dependency on whether the first shutter 30 and additionally or alternatively the second shutter 40 is in the closed position or the opened position 90, respectively.

Fig. 2a shows a rear view of the shutter arrangement 28, wherein -as well as in Fig. 1 -the shutter elements 26 of the first shutter 30 and the second shutter 40 are in the closed position 80 at present. The actuator 50 is arranged between the first shutter 30 and the second shutter 40 at present, wherein the actuator 50 is designed as a pivotable circular plate or disc. The actuator 50 is pivotable around a centre 58, wherein the actuator 50 is connected to the housing element 18 of the air guiding device 20. The actuator 50 is pivotably connected to the housing element 18 by means of a rotary joint, which is not shown here, and which is arranged at the centre 58 of the actuator 50. The shutter elements 26 of the first shutter 30 and the second shutter 40, respectively, are also pivotably connected to the housing element 18.

The first shutter 30 comprises a first connecting element 32 and the second shutter 40 comprises a second connecting element 42. The first connecting element 32 and the second connecting element 42 are designed as connecting bars at present. One end of the first connecting element 32 is pivotably connected to a first connecting rod 34, wherein the first connecting rod 34 is connected with each of the shutter elements 26 of the first shutter 30. The second connecting element 42 is pivotably connected to a second connecting rod 44, wherein the second connecting rod 44 is connected with each of the shutter elements 26 of the second shutter 40. Both the first connecting element 32 and the second connecting element 42 are connected with the first connecting rod 34 or the second connecting rod 44 respectively by means of connecting joints 100. The connecting joints 100 allow a rotary motion between the first connecting element 32 and the first connecting rod 34 or the second connecting element 42 and the second connecting rod 44, respectively, but the connecting joints 100 prevent a translational movement between the first connecting element 32 and the first connecting rod 34 or the second connecting element 42 and the second connecting rod 44, respectively. On their opposing ends the first connecting element 32 and the second connecting element 42 are connected with the actuator 50 by means of guiding joints 110. The guiding joint 110 of the first connecting element 32 extends into a first guiding element 60 of the actuator 50 and the guiding joint 110 of the second connecting element 42 extends into a second guiding element 70 of the actuator 50. The first guiding element 60 and the second guiding element 70 are each designed as guide slots, by means of which the first shutter and the second shutter 40 are moveable in dependency on a rotation 52 of the actuator 50. The first guiding element 60 is arranged on a front side of the actuator 50 and the second guiding element 70 is arranged on a rear side 56 of the actuator 50. In other words the guide slots (the first guiding element 60 and the second guiding element 70) are separated from each other.

Fig. 3a shows another rear view of the shutter arrangement 28 wherein the shutter elements 26 of the first shutter 30 are still in their closed position 80 but the shutter elements 26 of the second shutter 40 are moved into the opened position 90 in comparison with Fig. 2a. This is achieved by the rotation 52 of the actuator 50 by 90° around the y-axis and thus by the rotation 52 by 90°in counter clockwise direction around the centre 58 of the actuator 50. In other words the rotation 52 is carried out in a rotation plane 54, which is defined (spanned) by the x-axis and the z-axis of the coordinate system shown in Fig. 3b. The rotation plane 24 of the shutter rotation 22, which is shown in Fig. 1 and the rotation plane 54 of the rotation 52 of the actuator 50 are perpendicular to each other.

S

Due to the rotation 52 of the actuator 50 in counter clockwise direction by 90°the first connecting element 32 is kept at standstill, since the guiding joint 110 (of the first connecting element 32) slides along a curved area 62 of the first guiding element 60. The curved area 62 is designed as an arcuate groove with a radius which is smaller than that of the actuator 50. This arcuate groove (the curved area 62) extends along a quarter circle (along a 90°-segment of a circle), and thus along a quarter of the circumference of the actuator 50. The centre of the curved area 62 corresponds to the centre 58 of the actuator 50 and thus the guiding joint 110 (of the first connecting element 32), which protrudes into the curved area 62 is not moved but slides along the curved area 62 while the actuator 50 is rotated by 90° (rotation 52) in counter clockwise direction. In other words although the actuator 50 is rotated by 90°in counter clockwise direction, the first connecting element 32 and thus the first shutter 30 is kept at standstill. As a consequence the shutter elements 62 of the first shutter 30 are kept in the closed position 80.

In contrast to this, the shutter elements 26 of the second shutter 40 are moved from the closed position 80 into the opened position 90 due to the rotation 52 of the actuator 50 by 90° in counter clockwise direction. The guiding joint 110 of the second connecting element 42 protrudes into a straight area 74 of the second guiding element 70. The straight area 74 extends radially outwardly from the centre 58 and close to the circumference of the actuator 50. Due to the rotation 52 the guiding joint 110 and thus the second connecting element 42 is moved along the z-direction and the second connecting element 42 is simultaneously pivoted around the connecting joint 100 by means of which the second connecting element 42 is connected to the second connecting rod 44. Due to the movement in z-direction, the second connecting rod 44 is moved according to a second rod movement 46 and thus the shutter elements 26, which are connected with the second connecting rod 44 are rotated from the closed position 80 into the opened position 90.

Fig. 4a shows another rear view on the shutter arrangement 28, wherein the shutter elements 26 of both the first shutter 30 and the second shutter 40 are in the opened position 90. In order to achieve this the rotation 52 of the actuator 50 corresponds to a rotation by 180°in counterclockwise direction in comparison to the position of the actuator 50 which is shown in Fig. 2b. When the actuator 50 is rotated by 180°Un comparison with the position of the actuator 50 in Fig. 2b), the guiding joint 110, which extends into the second guiding element 70, slides along the straight area 74 (e.g. due to gravity or e.g. due to a spring force or another appropriate actuator, which is not shown in detail), until it reaches the centre 58. Meanwhile, the second connecting rod 44 is at standstill and the second shutter 40 is not moved. During the rotation 52, the first connecting element 32 is moved into the opposite z-direction and thus the first connecting rod 34 is also moved according to a first rod movement 36. The first rod movement 36 or the movement of the first connecting element 32 and the guiding joint 110. respectively, is achieved by the guiding of the guiding joint 110 by means of the curved area 62 and a straight area 64 (see Fig. 4b) of the first guiding element 60. In other words, the guiding joint 110 of the first connecting element 32 rests in an area of the first guiding element 60, where the curved area 62 changes over to the straight area 64.

Fig. 5a shows another rear view of the shutter arrangement 28 wherein the shutter elements 26 of the first shutter 30 are in the closed position 80 and the shutter elements 26 of the second shutter 40 are in the opened position 90. In contrast to the position of the actuator 50 in Fig. 4b, the actuator 50 is turned by 90° in clockwise direction (Fig. 5b) and thus the position of the actuator 50 is the same as in Fig. 3b. Due to the rotation 52 by 90° in clockwise direction, the first rod moveme nt 36 corresponds to a movement of the connecting rod 34 in z-direction and thus the first shutter 30 is moved from the opened position 90 (Fig. 4a) into the closed position 80 (Fig. 5a).

In contrast to Fig. 5a, in Fig. 6a the shutter elements 26 of the second shutter 40 are in the closed position 60. This is achieved by another rotation 52 of the actuator 50 by 90°in clockwise direction, wherein the actuator 50, which is shown in Fig. Sb, is in the same position as in Fig. 2b.

Fig. 7a to Fig. 11 b show another preferred embodiment of the shutter arrangement 28 and the actuator 50, respectively. In contrast to the shutter arrangement 28 and the actuator 50 which are shown in Fig. 2a to Fig. 6b, the second connecting element 42 is connected off-centre to the second connecting rod 44 by means of the connecting joint 100. In addition, the second guiding element 70 is designed as a curved area 72, which corresponds to an arcuate groove with a radius which is smaller than that of the actuator and which extends along a quarter circle as well as the curved area 62 of the first guiding element 60. In this embodiment, none of the guiding elements 60, 70 comprises a straight area 64, 74, but both comprise the curved area 62, 72. In this embodiment the second guiding element also comprises a catch nose 76, in which the guiding joint 110, which is connected to the second connecting element 42 may rest, if the guiding joint 110 is kept in the catch nose 76 due to gravity or e.g. a spring force or another appropriate actuator, which is not shown here. The guiding joint 110 may also be released from the catch nose 76, if the guiding joint 110 drops from the catch nose 76 due to gravity or if the guiding joint 110 is removed from the catch noise 76 by means of e.g. a spring force or another appropriate actuator, which is not shown here.

Fig. 7a shows the shutter arrangement 28, wherein the shutter elements 26 of the first shutter 30 and the second shutter 40 are both in the closed position 80. In the closed position 80, the actuator 50 is in a position which is shown in Fig. 7b.

In contrast to Fig. 7a, in Fig. Ba the shutter elements 26 of the second shutter 40 are moved into the opened position 90 due to the second rod movement 46 of the second connecting rod 44. In order to achieve this, the rotation 52 of the actuator 50 corresponds to a rotation by 90° in clockwise direction (see Fig. 8b).

In contrast to Fig. 8a, Fig. 9a shows both the shutter elements 26 of the first shutter 30 and of the second shutter 40 in the opened position 90. In order to achieve this, the actuator 50 is rotated by another 90° in clockwise direction (see Fig. 9b) compared to the position of the actuator 50 which is shown in Fig. 8b.

In contrast to Fig. 9a, Fig. ba shows the shutter elements 26 of the first shutter 30 in the closed position 80. In order to achieve this, the actuator 50 (shown in Fig. lOb) is rotated by 90° in counter clockwise direction compared to the position of the actuator 50 in Fig. 9b.

In contrast to Fig. 1 Oa, Fig. 11 a shows the shutter elements 26 of the second shutter 40 in the closed position 80. In Fig. 11 a the shutter elements 26 of the first shutter 30 and the second shutter 40 are in the closed position 80. In order to achieve this, the actuator (shown in Fig. llb) is rotated by 90°in counter clockwise direction compared to the position of the actuator 50 shown in Fig. lob. In other words the position of the actuator in Fig. llb corresponds to the position of the actuator 50 shown in Fig. 7b.

Fig. 2a to Fig. 11 b show different steps of operating the shutter arrangement 28 and the actuator 50 respectively of the air guiding device 20. The first shutter 30 and the second shutter 40 of the shutter arrangement 28 are moved between the closed position 80, in which the fluid flow 16 of the medium (air) through the air guiding device 20 is disabled, and the opened position 90, in which the fluid flow 16 through the air guiding device is enabled. The first shutter 30 and the second shutter 40 are also moved in dependency on the rotation 52 of the actuator 50 of the air guiding device 20. The actuator 50 comprises guide slots, by means of which the first connecting element 32 of the first shutter 30 and the second connecting element 42 of the second shutter 40 are moved and thus the first shutter 30 and additionally or alternatively the second shutter 40 are moved between the closed position 80 and the opened position 90.

Fig. 2a to Fig. 6b show an embodiment of the shutter arrangement 28 and the actuator 50, respectively, in which the connecting rods 34, 44 are pushed to move the shutters 30, into the opened position 90 and in which the connecting rods 34, 44 are pulled in order to move the shutters 30, 40 into the closed position 80.

Fig. 7a to Fig. 11 b show a further embodiment of the shutter arrangement 28 and the actuator 50, respectively, in which the connecting rods 34, 44 are pulled to move the shutters 30, 40 into the opened position 90 and in which the connecting rods 34, 44 are pushed in order to move the shutters 30, 40 into the closed position 80.

The selective movement of the shutters 30, 40 from the opened position 90 into the closed position 80 and vice versa can be achieved in dependency of the requirements of the vehicle components 12. In other words, the rotation 52 of the actuator 50 is performed in dependency of the requirements of the vehicle components 12. In aerodynamic studies of the vehicle, the reduction of the vehicle drag is an important aspect. To meet the targets of drag the fluid flow 16 (air flow) into the under hood (and thus into the air guiding device 20) has to be reduced. The designed flaps (shutter elements 26 of the shutters 30, 40) help to reduce the drag, if they are in the closed position 80 and thus the fuel economy can be increased. At least some of the shutter elements 26 have to be moved into the opened position 90, if at least one of the vehicle components 12 (e.g the combustion engine) crosses a critical temperature value (e.g. the water boiling temperature of 100°C at ambient pressure) and thus some of the vehicle components 12, like a charge air cooler, needs the fluid flow 16 for cooling.

In cold countries in winter seasons, it is important to keep the engine warm, so at least some of the shutter elements 26, or even all of them, have to be moved into the closed position 80 in order to keep the vehicle components 12 warm or to help them to warm up faster. In other words, the shutters 30, 40 are also operated in dependency on the temperature requirements of the vehicle components 12.

The shutter arrangement 28 allows the opening and closing of the shutters 30, 40 in sequence. This is achieved with especially low load on an ECU for signal triggering. The shutters 30, 40 are sequentially operated with one single drive, which corresponds to the actuator 50.
