Description

Technical Field

[0001] The present invention relates to a driving blade which is configured to be mounted on an active grille shutter device and to an active grille shutter device comprising such a driving blade. Background Art

[0002] Active grille shutter arrangements use controlled shutters or controlled vanes to control and regulate air flow to improve the aerodynamic and thermal performance of the vehicle.

[0003] An actuator with integrated electronics controls the opening and closing of the shutters. When air conditioning is required, the electronics control the opening of the shutters to improve the temperature. Conversely, when the temperature of the engine coolant allows, the system closes the shutters to reduce noise and consumption.

[0004] The current active grille shutter device includes a driving blade configured to be mounted on an actuator, a linkage device adapted to cooperate with the driving blade and a plurality of follower blades, and a frame configured to receive the driving blade and the actuator forming a subassembly. Therefore, the movement transmitted by the actuator to the driving blade drives the follower blades via the linkage device.

[0005] However, the current active grille shutter device assembly process is complicated by the fact that the operator cannot see the drive blade being inserted into the frame and then inserted into the actuator of the active grille shutter device because the drive blade is blocked by the linkage during insertion. This may cause the operator to make erroneous operations, which may damage the actuator of the active grille shutter device. In addition, this increases the cycle time required for the operator to assemble the active grille shutter device.

[0006] Therefore, there is a need to facilitate and simplify the assembly of an active grille shutter device including a drive blade by an operator, while ensuring the robustness of the active grille shutter device and the method of assembling the device. Summary of the invention

Thus, the manufacture of the drive blade becomes easier and the cycle time required for assembling the active grid shutter device is reduced. Thus, the costs of such a manufacture are reduced. Furthermore, the reduction in the number of parts of the drive blade allows the robustness of the drive blade to be improved.

[0139] In the various figures, identical elements are provided with identical reference numerals.

[0140] The following embodiments are examples. Although the description relates to one or more embodiments, this does not necessarily mean that each figure mark relates to the same embodiment, or that these features only apply to a single embodiment. The individual features of the various embodiments may also be combined or interchanged to produce other embodiments.

[0141] Figure 1An active grille shutter device 2 is shown in a side sectional view, which is used to close an air inlet for an air flow F arranged at the front end of a motor vehicle 4. The air flow F flows essentially parallel to a direction X, which corresponds to the longitudinal axis of the motor vehicle 4. The active grille shutter device 2 is in particular arranged behind a grille 6 mounted at the front end of the motor vehicle 4. A cooling module 8 is also placed behind the grille 6, which cooling module includes at least one heat exchanger 10, 12, through which the air flow F is intended to pass when the air flow enters the motor vehicle 4 via the grille 6. One or more heat exchangers 10, 12 extend in those planes that are parallel to the planes generated by the directions Y and Z of the coordinate frame XYZ. Figure 1 In the example shown, the cooling module 8 comprises more particularly two heat exchangers 10 and 12 which are arranged along the axis X downstream of the active grille shutter arrangement.

[0142] The cooling module 8 includes, for example, an upstream heat exchanger 10 ( Figure 1 ), and a downstream heat exchanger 12 ( Figure 1 In this particular arrangement, the air flow F passes first through the upstream heat exchanger 10 and secondly through the downstream heat exchanger 12.

[0143] The upstream heat exchanger 10 is, for example, a cooling radiator, known as a low-temperature cooling radiator, which serves to cool the coolant in a heat exchange circuit, known as a low-temperature circuit and comprising in particular an air conditioning condenser and / or a charge air cooler. The downstream heat exchanger 12 is, for example, a high-temperature cooling radiator, which is intended to cool the coolant in a heat exchange circuit, including the engine of the vehicle 4. The air passing through this downstream exchanger 12 cools the engine coolant.

[0144] Now, overall reference Figures 2 to 6 , which shows an active grille shutter arrangement 2 , which includes a subassembly 14 and a frame 16 configured to receive the subassembly 14 .

[0145] The subassembly 14 includes an actuator 18 configured to be assembled with a drive blade 20 configured to be mounted on the active grille shutter device 2. The subassembly 14 further includes a drive blade 20 configured to be assembled with the actuator 18.

[0146] The integrally formed drive blade 20 includes a connecting portion 22 and a lever 24, the connecting portion being configured to be mounted on the actuator 18, the lever being configured to cooperate with the linkage device 26 of the active grille shutter device 2 so as to transmit the movement of the drive blade 20 to the seven follower blades 28. The term 'integral' here means that the drive blade 20 is a single piece, rather than being formed by two separate elements connected to each other. For example, the drive blade 20 can be integrally formed by one-time complete manufacturing in a dedicated injection mold. The connecting portion 22 may include teeth 90 configured to engage with the tooth-shaped cavity 91 of the actuator 18.

[0147] The lever 24 that drives the blade 20 has a U-shaped hook 30 that is configured to cooperate with the linkage 26 .

[0148] The linkage 26 is adapted to cooperate with the lever 24 of the drive blade 20 and the follower blade 28 .

[0149] Reference now Figures 2 to 3 , details of the frame 16 are shown.

[0150] Especially reference Figure 3 , which shows the front side of the active grille shutter device 2, the frame 16 includes two side walls 32 connecting the upper wall 34 and the lower wall 36 and a middle part 38 bridging the upper wall 34 and the lower wall 36. The actuator 18 is mounted on the middle part 38 of the frame 16.

[0151] The middle portion 38 is between the two side walls 32 so as to create two apertures 40 on either side of the middle portion 38. Each aperture 40 is configured to receive a set of blades 120, the set of blades comprising a driving blade 20 and a plurality of follower blades 28. Only one of the blades in the set of blades 120 comprises a driving blade 20. The set of blades 120 comprises a driving blade 20 and three follower blades 28. The other set of blades 120 comprises four follower blades 28.

[0152] The frame 16 includes an opening 42 arranged to receive an electrical connection portion 44 of the actuator 18 of the subassembly 14. The opening 42 is aligned with the longest length of the intermediate portion 38.

[0153] The middle portion 38 includes a blade cover 50 that is arranged to partially cover the driving blade 20 and the following blade 28 .

[0154] refer to Figure 3 , the middle portion 38 is symmetrical with respect to the two side walls 32 so that the two openings 40 have the same size.

[0155] In one possible embodiment not shown, the middle portion 38 may be asymmetrical with respect to the two side walls 32 , such that the two apertures 40 have different sizes.

[0156] Thanks to the present invention, the number of parts forming the drive blade 20 is reduced. Therefore, the manufacture of the drive blade 20 can be made easier and the cycle time required for assembling the active grille shutter device 2 is reduced. Therefore, the cost of such manufacture is reduced. In addition, the reduction in the number of parts of the drive blade 20 allows the robustness of the drive blade 20 to be improved.

[0157] The presence of the lever 24 and the connecting portion 22 allows the operator to see the drive blade 20 when assembling the drive blade 20 and the actuator 18. For example, the drive blade 20 and the actuator 18 can be assembled together to form the subassembly 14 before inserting the drive blade into the frame 16 of the active grille shutter device 2. In this way, the risk of damaging the actuator 18 during the assembly process of the active grille shutter device 2 is suppressed.

[0158] The presence of the lever 24 allows the drive blade 20 to be compatible with actuators 18 that are not configured to directly cooperate with the connecting portion 22. In other words, a connection is provided between the actuator 18 (having an output shaft) and the drive blade 20 (the starting shaft) through which the entire torque is transmitted to the drive blade 20. The lever 24 (arm section) is then integrated into the drive blade 20 (the starting shaft) to transmit this torque to the rest of the drive blade 20 through the linkage 26.

[0159] The active grille shutter device 2 allows the actuator 18 to drive two sets of blades 120 located on either side of the actuator 18 while reducing the cost of the device 2 and the cost of assembling the device 2 .

[0160] The driving blade 20 may be molded together with the follower blade 28 in the same mold.

The blade 52 includes an outer arch 54 and an inner arch 56 having a plurality of ribs 58 forming a honeycomb structure. The drive blade 20 includes an end 59 configured to mate with one of the side walls of the frame 16.

[0162] Reference now Figures 5 and 6 , details of the linkage 26 and the lever 24 are shown.

[0163] The linkage 26 comprises a pin 60 configured to cooperate with the lever 24. The pin 60 forms a bridge between two flanges 62 of the linkage 26. The linkage 26 is made in one piece and is a moulding.

[0164] The linkage 26 is movable between two end positions, which correspond to a completely open position of the active grille shutter arrangement 2 and a closed position of the active grille shutter arrangement 2 .

[0165] The cooperation between the pin 60 and the lever 24 allows the linkage 26 to be moved between these two end positions.

[0166] The linkage 26 includes an elliptical slot 64 arranged to expose a bridge portion of the linkage 26 and the lever 24 driving the blade 20 .

[0167] The linkage 26 is configured to be connected to all follower blades 28. In other words, only one linkage 26 is required for all follower blades 28.

[0168] like Figure 5 and Figure 6 As shown, the linkage 26 comprises two lateral connecting walls 66 which are parallel to each other. Each lateral connecting wall 66 is connected to a follower blade 28.

[0169] The linkage 26 comprises a flat base wall 68 between two lateral connecting walls 66 so as to form a U-shaped cross section.

[0170] The oval slot 64 is formed in a flat base wall 68 of the linkage 26 .

[0171] refer to Figure 5 The follower blades 28 each include a first end 70 configured to mate with the intermediate portion 38 and a second end 72 configured to mate with the linkage 26 .

[0172] refer to Figure 6 , the lateral connecting wall 66 of the linkage 26 comprises holes 74. Each hole 74 is arranged to receive the second end 72 of the follower blade 28. The middle portion 38 comprises two lateral connecting walls 80 parallel to each other. Each lateral connecting wall 80 is connected to the follower blade 28.

[0173] The follower blade 28 includes a plate 83 at one of the sides of the follower blade 28, wherein the plate 83 includes the first end 70 and the second end 72 of the follower blade 28. These first end 70 and the second end 72 have a cylindrical shape. The size (e.g., diameter) of the first end 70 is larger than that of the second end 72.

[0174] One of the side connecting walls 80 includes a U-shaped rod bracket 82 configured to receive the rod 53 of the drive blade 20. The side connecting walls 80 include holes 86. Each hole is arranged to receive the first end of the follower blade 28 and the connecting portion 22 of the drive blade 20. The middle portion 38 has a top cover portion 84 between the two side connecting walls 80 so as to form a U-shaped cross-section.

[0175] Reference now Figure 7 , details of a method 200 for assembling an active grille shutter arrangement 2 are shown.

[0176] The method 200 comprises the following steps:

[0177] - forming the subassembly 14 including the actuator 18 and the drive blade 20 (step 210);

[0178] - Installing the subassembly 14 into the frame 16 of the active grille shutter arrangement (step 220 ).

[0179] Thanks to the invention, the assembly process has become simpler and more cost-effective.

[0180] The method 200 further comprises the step of attaching the actuator 18 of the subassembly 14 into the frame 16. The actuator 18 is attached into the frame 16 by a threaded connection.
