Description

Technical Field

[0001] The present invention relates to an air inflow control device for a motor vehicle, and in particular to the field of a baffle panel for an air intake of a motor vehicle. Background Art

[0002] The front face of a motor vehicle usually includes an air intake and a fender panel mounted behind the air intake of the vehicle, which may also be denoted by a grille or the abbreviation AGS ("Active Grille Shutter").

[0003] The damper panel can open or close the incoming air through the vehicle motor grille.

[0004] In the open position, air can flow through the grille and participate in the cooling of the motor vehicle engine. In the closed position, air does not enter through the grille, which reduces resistance and can thus reduce fuel consumption and CO2 emissions.

[0005] Active grille flaps can therefore reduce energy consumption and pollution when the engine does not need to be cooled by outside air.

[0006] Active grille flaps conventionally include an actuator (also called an actuator or a motor) which controls the flap and enables the inlet air flow to be opened or closed. The flap is opened when the engine of the motor vehicle requires cooling and is closed when the engine of the motor vehicle is sufficiently cooled.

[0007] The baffles are in the form of horizontal or vertical blades, pivotably mounted about each central baffle axis on the panel. The inclination of the baffles can be controlled between a vertical blocking position blocking the passage of air and a plurality of intermediate positions leading to an open position, in which maximum airflow can flow.

[0008] Systems comprising pairs of active and passive baffles are also known. In the open position, the active baffles can be moved in translation behind the passive blades and the fixed blades.

[0009] However, in all of these systems, the vanes remain in the air inlet in the open position, thereby interfering with the passage of air. Summary of the invention

[0010] It is an object of the present invention to provide an air inflow control device which is optimized for better cooling performance and has reduced costs.

[0011] To this end, the present invention relates to an air inflow control device for a motor vehicle, comprising:

[0012] - a frame in which at least one air inlet is arranged, and

[0013] - at least two baffles behind said at least one air inlet,

[0014] Characterized in that the baffles are interconnected, and the air inflow control device further comprises a baffle actuator device, which is configured to drive a driving baffle in the at least two interconnected baffles,

[0015] - so as to stack at least two interconnected baffles one behind the other in sequence, said at least two interconnected baffles being stacked one behind the other behind the edge of said at least one air inlet in the open position, and

[0016] - so as to unpack the at least two interconnected baffles one after the other in sequence, the at least two interconnected baffles being arranged one next to the other in the closed position.

[0017] Since in the open position all baffles are stacked behind the edge of the at least one air inlet, a maximum air flow can circulate. With this arrangement, a better cooling performance can be performed in the open position. In addition, the aesthetics of the opening and closing sequence is improved. In addition, the signature of the builder can be recognized. Moreover, this arrangement is easy to manufacture.

[0018] The air inflow control device may also include one or more of the features described below, alone or in combination.

[0019] In the closed position, the at least two interconnected baffles may be arranged horizontally one above the other.

[0020] The driven shutter may be the lowermost shutter in the closed position.

[0021] The opening sequence toward the open position may follow an opening direction from bottom to top, and the closing sequence toward the closed position may follow a closing direction from top to bottom.

[0022] The air inflow control device may include at least two air inlets, and the at least two interconnected baffles behind the at least two air inlets are horizontally aligned at least in pairs. The driving baffle of each of the at least two interconnected baffles behind each of the at least two air inlets may be driven by a baffle actuator device. Therefore, since only one baffle actuator device is required, the cost can be reduced.

[0023] According to one embodiment, the at least two interconnected baffles each include at least one corresponding first pin, and the air inflow intake device also includes at least one connecting member, which includes a hole in which the first pin of the baffle is engaged and a slide rail in which the first pin of the adjacent baffle can slide.

[0024] According to one embodiment, a flap actuator arrangement comprises a rotary actuator and a pivoting lever having one end connected to the actuator and one end cooperating with at least one drive flap.

[0025] The frame includes frame slots parallel to each other, and the at least two interconnected baffles each include at least one corresponding second pin, which slides in the corresponding frame slot, and the driving baffle also slides in the slot formed in the rod, so that the at least two interconnected baffles move in their corresponding frame slots along with the angular movement of the rod provided by the actuator.

[0026] The frame may include an additional frame slot parallel to the frame slot, in which the at least one first pin may also slide.

[0027] According to another embodiment, a flap actuator device comprises a rotary actuator, a pinion mounted on a shaft of the actuator, and a curved rack connected to a drive flap of the interconnected flaps, the curved rack meshing with the pinion.

[0028] The frame may include frame slots parallel to each other, and the at least two interconnected baffles include at least one corresponding first pin that slides in the corresponding frame slot so that the interconnected baffles move in their corresponding frame slots as the curved rack is moved by the actuator.

[0049] In the following description, on a non-limiting basis, longitudinal, vertical and transverse directions will be used, such as Figure 1 The trihedron (X, Z, Y) fixed relative to the frame is shown in FIG. The longitudinal direction Y corresponds to the main direction of the blades of the baffle. The terms "upper" and "lower" refer to the vertical direction Z.

[0050] In the following description, the same or similar elements will be denoted by the same reference numerals. DETAILED DESCRIPTION

[0051] The following achievements are examples. Although the specification relates to one or more embodiments, this does not mean that each reference numeral refers to the same embodiment or that the features apply to only a single embodiment. Simple features of different embodiments may also be combined to provide other embodiments.

[0052] Figure 1 and Figure 2 A first example of an air inflow control device 1 for a motor vehicle is shown.

[0053] The air inlet device 1 comprises a frame 2, in which at least one air inlet 3, 4 is arranged. Figure 1 ) are provided with two air intakes 3, 4, but a different number is possible, which enables air to flow from the front of the vehicle towards the engine to cool the engine.

[0054] The air inflow inlet device 1 further comprises at least two baffles 5 , 6 , 7 , 8 behind each air inlet opening 3 , 4 , for example two to ten baffles, here four baffles 5 - 8 behind each air inlet opening 3 , 4 .

[0055] from Figure 3 As can be better seen in FIG. 1 , each baffle 5 - 8 comprises a blade extending longitudinally (along the Y direction), which is a rectangular plate-shaped blade here.

[0056] Behind each air inlet 3, 4, baffles 5-8 are arranged one next to the other in the closed position. Adjacent baffles 5-8 behind each air inlet 3, 4 may have a matching shape to engage the edges of adjacent baffles 5-8 in the closed position ( Figure 4 ).

[0057] The baffles 5-8 may be arranged horizontally as shown, ie the baffles 5-8 are arranged one above the other in the closed position, or the baffles 5-8 may be arranged vertically (not shown). In the following description, the horizontally arranged baffles 5-8 will be described.

[0058] When the air inflow control device 1 comprises at least two air inlets 3, 4, the baffles 5-8 behind each air inlet 3, 4 may be horizontally aligned at least in pairs, such as Figure 3 shown.

[0059] Behind each air inlet 3, 4, the baffles 5-8 are interconnected. In other words, the baffles 5-8 are connected to each other. The connection is arranged so that one can be allowed to move to a certain extent without the other moving.

[0060] Each baffle 5-8 is connected to an upper one and / or a lower one and / or a side one (in a horizontal arrangement, the side one is behind the other air inlet 3, 4).

[0061] According to an interconnected embodiment of the baffles 5 - 8 behind one air inlet 3 , 4 , each interconnected baffle 5 - 8 comprises at least one respective first pin 10 , for example two first pins 10 on each longitudinal end.

[0062] The air inflow intake device 1 further comprises at least one connecting member 12, which comprises a slide rail and a hole, in which the first pin 10 of the first baffle is engaged, and the first pin 10 of the adjacent baffle slides in the slide rail to interconnect the two adjacent baffles 5-8.

[0063] The first pin 10 may extend transversely (in the Y direction) to the plane of the blade ( Figure 4 ).

[0064] In this example, the connecting member 12 has an "L" shape, with the angle between the two legs being less than 90°. The slide rail is straight and formed in the longer leg, with the hole formed in the end of the other leg.

[0065] As an example, Figure 4 As shown, it is more clearly visible that the baffles 5-8 are connected in pairs, a connecting piece 12 is between two adjacent baffles 5-8 behind each air inlet 3, 4, and the connecting pieces 12 are alternately arranged on one side of the baffle 5-8 and the other side of the baffle 5-8. Therefore, in this example, the air inflow device 1 includes six connecting pieces 12.

[0066] The air inflow control device 1 also includes a baffle actuator device 13, which is configured to drive the driving baffle 8 of the interconnected baffles 5-8 so that the interconnected baffles 5-8 are stacked one after another in the open position, and the interconnected baffles 5-8 are stacked one behind the other behind the edge of the at least one air inlet 3, 4, and so as to detach the interconnected baffles 5-8 one after another in the closed position.

[0067] The flap actuator device 13 is configured to move the driving flap 8 and, due to the interconnection of the flaps 5 - 8 , the driving flap 8 drives the driven flaps 5 - 7 one after another behind each air inlet 3 , 4 .

[0068] The driving baffle 8 may be the lowermost baffle in the closed position. The opening sequence towards the open position then follows an opening direction from bottom to top, in which the interconnected baffles 5-8 are stacked behind the upper edge of the air inlets 3, 4. The closing sequence towards the closed position follows a closing direction from top to bottom.

[0069] In another example not shown, the driving baffle is the upper baffle 5 , the opening direction is from top to bottom, and the closing direction is from bottom to top.

[0070] In another example, not shown, the baffles 5 - 8 are arranged vertically one next to the other, with the driven baffle being the rightmost or leftmost.

[0071] exist Figure 3 In the embodiment shown, the flap actuator device 13 comprises a rotary actuator 14 and a pivot rod 15. The rotary actuator 14 may be mounted on the frame 2, for example on a wall of the frame 2 arranged between the two air inlets 3,4.

[0072] The rod 15 has one end connected to the actuator 14 and one end cooperating with at least one drive flap 8 .

[0073] As an example, the end of the rod 15 cooperates with the drive baffle 8 behind each air inlet 3, 4. To this end, the end of the rod 15 can cooperate with the connector 16 connected to each drive baffle 8 ( Figure 3 ).

[0074] According to one embodiment, the at least two interconnected baffles 5-8 comprise at least one respective second pin 11, for example two second pins 11 at each longitudinal blade end. These second pins 11 may be offset (in the X direction) from the blade plane and thus from the first pin 10. Both the first pin 10 and the second pin 11 may be formed on the side plate of each end baffle 5-8.

[0075] The connector 16 may be a tube in which each transverse second pin 11 of the two drive baffles 8 engages.

[0076] All baffles 5 - 8 may be identical and may be made of plastic by casting.

[0077] According to one embodiment, a rod slot is formed in the rod 15 in which a connector 16 connected to the second pins 11 of the two drive flaps 8 can slide.

[0078] According to one embodiment, the frame 2 includes at least one frame slot 18 that cooperates with the corresponding baffle 5-8, where each baffle 5-8 corresponds to two frame slots 18, one on each side of each baffle 5-8, and the frame slots 18 are parallel to each other ( Figure 2 ).

[0079] In this first example, the frame slot 18 is straight, just like the slot formed in the rod 15 .

[0080] The second pins 11 of the interconnected driven baffles 5 - 7 slide in the corresponding frame slots 18 .

[0081] Furthermore, the second pins 11 of the drive flaps 8 slide on the one hand in the corresponding frame slots 18 and on the other hand in the slots formed in the rod 15, here via the connector 16 connected to the second pins 11 of the two drive flaps 8. This allows the interconnected flaps 5-8 to move in their corresponding frame slots 18 following the angular movement of the rod 15 provided by the actuator 14.

[0082] According to one embodiment, the frame 2 comprises an additional frame slot 19 parallel to the frame slot 18 in which the at least one first pin 10 also slides. As an example, on each side of each baffle 5-8, an additional frame slot 19 is made parallel to each frame slot 18.

[0083] The drive flap 8 slides here simultaneously in the slot of the rod 15, in the frame slot 18 and in the additional frame slot 19 via the connector 16. Due to these constraints, the drive flap 8 moves in its respective frame slot 18, 19 following the angular movement of the rod 15 provided by the actuator 14, here inwardly when the rod 15 pivots from bottom to top during the opening sequence and outwardly when the rod 15 pivots from top to bottom during the closing sequence.

[0084] The interconnection of the baffles 5-8, here by means of connectors 12 between adjacent horizontal baffles 5-8 and by means of connectors 16 between the drive baffles 8, allows for sequential stacking and unstacking of the interconnected baffles 5-8 one after the other.

[0085] FIG. 5A to FIG. 6D Different successive opening positions of the shutters 5 - 8 in an opening sequence are shown.

[0086] Figures 5A to 5E Four consecutive steps of the opening sequence are shown. When the air inlets 3, 4 open or close the flaps one after the other, the opening sequence comprises as many steps as the number of flaps 5-8 of the air inlets 3, 4.

[0087] Figure 1 , Figure 2 and Figure 5A The air inflow control device 1 is shown in an initial closed position. The interconnected baffles 5-8 are arranged one above the other, blocking the air inlets 3,4.

[0088] Fig. 6ASequential views of the air inflow control device 1 are shown. When the actuator 14 starts to rotate, the rod 15 pivots upwards, and as a result, the connector 16 connected to the second pin 11 of the drive flap 8 moves inwards in the slot of the rod 15. The second pins 11 of the drive flap 8 move upwards in their corresponding frame slots 18. The first pins 10 of the drive flap 8 move upwards in their corresponding frame slots 18. The other flaps 5-7 remain closed and do not move.

[0089] The driven baffle 8 moves along the frame slot 18 , parallel to the other stationary baffles 5 - 7 , until being stacked in parallel behind the preceding baffle 7 and hidden by it.

[0090] Once the drive baffle 8 of each air inlet 3, 4 is positioned behind and parallel to the penultimate baffle 7 ( Figure 5B and 6B ), due to the interconnection, and while the actuator 14 is still rotating, the two baffles 7, 8 start to move upwards together ( Figure 6C ). The other baffles 5-6 remain closed and do not move.

[0091] Once the lowermost and second to last baffle 8, 7 of each air inlet 3, 4 is positioned behind and parallel to each second uppermost blade 6 ( Figure 5C In the second step shown in FIG), due to the interconnection, the three baffles 6, 7, 8 start to move upward together. The other baffle 5 remains closed and does not move.

[0092] Once all baffles 5-8 are positioned one behind the other and behind the uppermost baffle 5 (eg Figure 5D In the third step shown), all baffles 5-8 begin to move upward together.

[0093] In the open position ( Figure 5E and Fig.6D In the fourth and last step shown in FIG. 1 ), the interconnected baffles 5-8 are stacked one behind the other behind the upper edge of the at least one air inlet 3, 4. Since all baffles 5-8 are stacked behind the edge of their respective air inlet 3, 4, a maximum air flow can circulate.

[0094] With this arrangement, better cooling performance can be performed in the open position. In addition, the aesthetics of the opening and closing sequence is improved. In addition, the builder's signature can be recognized.

[0095] When the air inflow control device 1 includes more than one air inlet 3, 4, the driving damper 8 of each air inlet 3, 4 can be driven by the same damper actuator device 13. Therefore, only one damper actuator device 13 is required, and the cost is reduced.

[0096] This arrangement is easy to manufacture.

[0097] Figure 7 and Figure 8 A second example of an air inflow control device 1 for a motor vehicle is shown. Only elements that differ from the first example are described.

[0098] Here, the air inflow into the air intake device 1 comprises two air intake ports 3 , 4 and three baffles 5 , 6 , 7 behind each air intake port 3 , 4 .

[0099] Each baffle 5 - 7 comprises a curved blade and in the closed position the baffles 5 - 7 are arranged one above the other.

[0100] Each baffle 5 - 7 comprises at least one respective first pin 10 cooperating with the frame 2 , for example two first pins 10 arranged on each side of each baffle 5 - 7 .

[0101] The baffles 5-7 behind the first air inlet 3 and the second air inlet 4 are aligned horizontally in pairs and connected in pairs, for example by respective connectors 16 interposed therebetween, such as tubes in which the first pins 10 inside the baffles 5-7 engage. In this example, the air inflow control device 1 comprises three connectors 16, because there are three baffles 5-7. Therefore, the aligned baffles 5-7 of the two air inlets 3, 4 move simultaneously.

[0102] The air inflow intake device 1 also includes at least one connection member 12, which includes a hole in which the first pin 10 of the baffle 5-7 engages and a slide rail in which the first pin 10 of the adjacent baffle 5-7 can slide, these first pins 10 are for example located on the outside of each baffle 5-7. In this example, the slide rail is slightly curved.

[0103] according to Figure 8 , in which the aligned baffles 5-8 behind the two air inlets 3, 4 are connected by a connector 16, the baffles 5-7 are interconnected two by two, and a connector 12 is interposed between two adjacent baffles 5-8, once behind the first air inlet 3 and once behind the second air inlet 4. Thus, in this example, the air flow into the air inlet device 1 includes two connectors 12.

[0104] In this example, the baffle actuator device 13 includes a rotary actuator 14, a pinion 20 mounted on the shaft of the actuator 14, and a curved rack 21 connected to the driving baffle 7 (here the lowermost baffle) of the interconnected baffles 5-7, the curved rack 21 meshing with the pinion 20 ( Fig. 9 ).

[0105] The rotary actuator 14 and the pinion 20 may be mounted on the frame 2 , for example the actuator 14 is mounted on a first wall and the shaft of the pinion 20 is free to rotate on a second wall, both walls being arranged between the two air inlets 3 , 4 .

[0106] The curvature of the rack 21 is, for example, an arc. The frame 2 may further include an arc guide 22, for example, having a "T" shape and protruding from the second wall of the frame 2. The arc guide 22 cooperates with a complementary groove of the curved rack 21 to guide the movement of the curved rack 21.

[0107] The frame 2 comprises at least one frame slot 18 for each baffle 5-7, wherein each baffle 5-7 has two frame slots 18, one on each side of each baffle 5-7, the frame slots 18 being parallel to each other ( Figure 7 ).

[0108] In this example, the frame slots 18 are curved. They have the same curvature as the curved rack 21 to follow the bending motion imposed by the cooperation of the curved rack 21 and the pinion 20 rotated by the actuator 14. The arc guides 22 are parallel to the curved frame slots 18 ( Fig. 9 ).

[0109] Each baffle 5-7 of at least one air inlet 3, 4 comprises at least one first pin 10 sliding in a corresponding frame slot 18. Here, each baffle 5-7 comprises one first pin 10 on each side, which slides in a corresponding frame slot 18. Thus, some of the outer first pins 10 slide both in the frame slot 18 and in the slide rails of the connection piece 12.

[0110] Furthermore, the first pins 10 of the two drive flaps 7 are also driven by the curved rack 21, here via the connector 16. By way of example, the curved rack 21 comprises a hole into which the connector 16 is inserted.

[0111] Through these constraints, the drive flaps 7 move in their respective frame slots 18 following the movement of the curved racks 21 provided by the actuator 14 .

[0112] Figure 7 , 10A 10C show different successive opening positions of the shutters 5 - 7 in the opening sequence.

[0113] Figure 7 The air inflow control device 1 is shown in an initial closed position. The baffles 5-7 extend horizontally and are arranged one above the other, blocking the air inlets 3,4.

[0114] Fig. 10AThere are shown sequential views of the air inflow control device 1. When the actuator 14 and therefore the pinion 20 rotates, the curved rack 21 is pulled upwards, causing the drive flap 7 of each air inlet 3, 4 to move upwards as they are connected by the connector 16. The other flaps 5-6 remain closed and do not move.

[0115] Therefore, the pins 10 of the driving baffle 7 move inwardly in their corresponding frame slots 18, and as a result, the driving baffle 7 moves along the frame slots 18 until it is parallel to the position of the previous baffle 7 ( Fig. 10B ).

[0116] Once the driving flap 7 of each air inlet 3, 4 is positioned behind and parallel to the penultimate flap 6, due to the interconnection, and while the actuator 14 is still rotating, the two flaps 6, 7 begin to move upwards together. The other flap 5 remains closed and does not move.

[0117] Once all baffles 5-7 are positioned one behind the other behind the uppermost baffle 5, all baffles 5-7 begin to move upwards together until they reach the open position ( Fig. 10C ), wherein all baffles 5-7 are stacked one on top of the other behind the edge of the at least one air inlet 3, 4. A maximum air flow can flow.

[0118] This arrangement is easy to manufacture and saves space.

[0119] Other embodiments of the flap actuator arrangement 13 are possible, such as a belt drive, a plurality of coupled gears or other electrical actuator arrangements.
