Description

Title of the invention: Airflow direction module in a passenger compartment of a motor vehicle

[0001] The invention relates to the ventilation systems of a motor vehicle. The invention deals with the direction of an airflow exiting a ventilation duct in a motor vehicle passenger compartment. More specifically, the invention relates to an airflow direction module injected into a passenger compartment of a motor vehicle. The invention also relates to a motor vehicle. The invention also relates to a method for manufacturing an airflow direction module for a motor vehicle.

[0002] Vehicles typically have air vents located in the passenger compartment, the purpose of which is to introduce conditioned air into the vehicle's interior. These vents are, for example, installed on the vehicle's dashboard. It is also known to create a vent in which the direction of the outgoing airflow is modified using the Coanda effect. The Coanda effect is the tendency of a moving fluid to flow along convex surfaces. Thanks to this effect, it is possible to guide the outgoing flow by distributing it among different channels with specific surface geometries within the vent.This allows the direction of the airflow exiting the aerator to be managed without using movable guide vanes, and the visible cross-section of the aerator to be reduced without reducing performance: for example, by using the Coanda effect to manage the vertical direction of the airflow, the visible cross-section of the aerator along this vertical axis can be reduced.

[0003] However, a passenger compartment air circulation system is not limited to the visible part of an air vent. The system also includes an air conditioning production system to supply air at the desired temperature to the passenger compartment, as well as air ducts and guides to carry the air from the air conditioning production system to the vents distributed throughout the passenger compartment.

[0004] To ensure optimal comfort for the occupants of the passenger compartment, particularly with regard to aerodynamics and noise, pressure losses in the airflow and ventilation noise must be avoided. Specifically, to fully benefit from the advantages of using the Coanda effect in the design of an air circulation system, the airflow within said system must remain as laminar as possible. The junctions between the various ducts and air guide sections may have defects that disrupt the laminar airflow and generate noise and pressure losses.

[0005] Document DE102021123760A1 describes a ventilation device for the passenger compartment of a motor vehicle. The ventilation device regulates and modifies the direction of airflow exiting the ventilation unit. It comprises a housing with an air inlet in a first section of the housing and an outlet opening to the passenger compartment of the motor vehicle.

[0038] In the following description, the term "include" is synonymous with "include" and is not limiting in that it permits the presence of other elements in the motor vehicle or other steps in the process to which it relates. It is understood that the term "include" includes the terms "consist of." The terms "external" and "internal" shall respectively designate what is directed outward from the vehicle and inward from the vehicle.

[0039] In this description, the terms "longitudinal," "longitudinally," "transverse," and "transversely" are used with respect to the vehicle's frame of reference in the mounting configuration. "Longitudinal" refers to the vehicle's principal direction of travel. "Transverse" refers to a direction perpendicular to the vehicle's principal direction of travel.

Indeed, they allow an inclination of at most 20°, preferably at most 10°, more preferably at most 5°, and even more preferably at most 2°; with respect to the strict meaning of these terms.

[0044] In this description, the technical characteristics are defined in the mounting configuration of the orientation module, unless otherwise explicitly stated.

[0045] Throughout the description, the different figures use the same reference signs to designate identical or similar entities.

[0046] Figure 1 represents a motor vehicle 10 according to the invention. The motor vehicle 10 comprises energy storage means and at least one motor (not shown) adapted to drive said motor vehicle 10.

[0047] The motor vehicle 10 includes a structure 12 delimiting the passenger compartment 14 of the motor vehicle 10. The passenger compartment 14 is intended to accommodate the occupants (not shown) of the motor vehicle 10. The passenger compartment 14 houses at least one seat. The structure 12 supports various openings providing access to the passenger compartment 14 or to other compartments. At the front, the passenger compartment 14 is delimited by a dashboard 16. The dashboard 16 extends transversely across the entire width of the passenger compartment 14. It houses various vehicle controls, as well as display devices.

[0048] To ensure the comfort of the occupants, including the driver and passengers (not shown), the motor vehicle 10 includes a ventilation system 18. The ventilation system 18 allows for the renewal and recirculation of air in the passenger compartment 14. It is preferably equipped with an air heating and cooling device. It is capable of dehumidifying the air. The ventilation system 18 may be an air treatment system supplied to the passenger compartment 14.

[0049] The ventilation system 18 is controlled by a control unit 20. The control unit 20 can be a computer, such as the on-board computer of a motor vehicle, or a programmable electronic board. Its memory (not shown) stores computer program code instructions. Its processor (not shown) executes a control program based on received instructions and measurements.

[0050] The motor vehicle may, for example, be a private motor vehicle or a utility motor vehicle.

[0051] Figure 2 shows an airflow direction module 22 for the passenger compartment. Passenger 14 of a motor vehicle. The motor vehicle may correspond to the one shown in relation to [Fig. 1]. The orientation module 22 has a first air distribution slot. A second slot is shown in the background.

[0052] The orientation module 22 comprises a housing 26. The housing 26 forms a box containing various components and parts. It provides a distribution duct that guides the airflow 24 through the orientation module 22. The housing 26 is connected to the heating and cooling device.

[0053] The housing 26 comprises: a first wall 28 and a second wall 30. The second wall 30 is opposite the first wall 28. They are generally parallel. They form the outer shell of the housing 26. They are airtight. The housing 26 also includes a guide body 32 for the airflow 24 flowing between the first wall 28 and the second wall 30. The guide body 32 is ogive-shaped. The guide body 32 is essentially hollow. It forms a shell. It occupies a central position along the vertical thickness of the housing.

[0054] The guide body 32 separates a first arched channel 34 from a second arched channel 36. The first arched channel 34 is bounded by the first wall 28 and the guide body 32, while the second arched channel 36 is bounded by the second wall 30 and the guide body 32. The housing 26 also has an inlet passage 38 upstream of the guide body 32, and an outlet passage 40 towards the passenger compartment 14. The first arched channel 34 is inclined relative to the second arched channel 36. Downstream, they converge in the outlet passage 40. The housing 26 defines a flow direction 42.

[0055] The inlet passage 38 includes a pivoting flap 44. The pivoting flap 44 is configured to move between a first position (not shown) against the first wall 28, a second position (not shown) against the second wall 30, and a plurality of intermediate angular positions. The movements, and therefore the positions, of the pivoting flap 44 allow control and modulation of the proportions of airflow 24 passing through the first arched channel 34 and the second arched channel 36. Since the channels are inclined, this feature allows control of the general exit direction of the airflow.

[0056] The pivoting flap 44 forms a plate. It includes magnetic means 46 in the entry passage 38. The magnetic means 46 are located between the first wall 28 and the second wall 30. Preferably, the magnetic means 46 comprise a permanent magnet or iron. According to one option, the magnetic means comprise an electromagnetic source.

[0057] The first wall 28 and / or the second wall 30, preferably each of it, includes an electromagnetic device 50 capable of generating a magnetic field in the inlet passage 38 in order to exert a force on the magnetic means 46 so as to move the pivoting flap 44 between the first position and the second position.

[0058] The invention arranges the moving part of the magnetic actuator of the pivoting flap 44 directly in the inlet passage 38. This avoids drilling through the first wall 28 or the second wall 30, which could generate leaks and thus a loss of efficiency. The actuation force is exerted through the walls. This feature also simplifies manufacturing and reduces the number of parts to be assembled.

[0059] The housing 26 includes at least one airtight partition 52 between the, preferably each, electromagnetic device 50 and the pivoting flap 44. Each airtight partition 52 forms a barrier and is formed by one of the walls. They prevent air leakage at each electromagnetic device 50.

[0060] The housing 26 comprises an inlet element 54 and an outlet element 56 attached to the inlet element 54. They form two sleeves. For example, they are fixed longitudinally in an assembly motion. The pivoting flap 44 is connected to the outlet element 56. It is integral with the outlet element 56. The electromagnetic device(s) 50 are connected to the inlet element 54. The inlet element 54 carries each electromagnetic device 50. For example, the inlet element 54 forms and delimits the inlet passage 38. For example, the outlet element 56 forms the outlet passage 40.

[0061] The inlet element 54 includes a mounting edge 58 for the outlet element 56. The mounting edge 58 forms a loop surrounding the outlet element 56. It includes mounting tabs and / or mounting holes. Each electromagnetic device 50 is located at a distance from said mounting edge 58. This feature facilitates the installation of the mounting means. The multi-element construction facilitates their molding and simplifies the assembly of the pivoting flap.

[0062] The electromagnetic device 50 is a first electromagnetic device 60 against the first wall 28. The second wall 30 includes a second electromagnetic device 62. The second electromagnetic device 62 is capable of generating a magnetic field in the entrance passage 38 in order to exert a force on the magnetic means 46 so as to move the pivoting flap 44 between the first position and the second position. Each electromagnetic device 50 is capable of attracting or repelling the pivoting flap 44 via its magnetic means 46. They are functionally identical. The magnetic means 46 are located between the first electromagnetic device 60 and the second electromagnetic device 62.

[0063] According to one embodiment of the invention, the orientation module 22 comprises elastic means (not shown) configured to retain the pivoting flap in the first position, or in the second position, or in the central position, or any intermediate position.

[0064] According to an alternative of the invention, the orientation module comprises a single electromagnetic device.

[0065] Figure 3 shows a cross-section of an airflow direction module 22 for supplying air 24 to a passenger compartment of a motor vehicle. The motor vehicle may correspond to the one shown in relation to one of Figures 1 to 2.

[0066] The inlet passage 38 houses a pivoting flap 44 in the housing 26. The pivoting flap 44 is able to oscillate by tilting from a first position (represented in dotted lines at the top) against the first wall 28 to a second position (represented in dotted lines at the bottom) against the second wall 30. The pivoting flap 44 is also able to occupy a central position (represented in solid lines).

[0067] For example, in the central position, the pivoting flap 44 is horizontal, or in the upstream extension of the guide body 32. The different positions of the pivoting flap 44 allow the airflow 24 to be divided between the first arched channel 34 and the second arched channel 36. The first arched channel 34 has an outlet direction that is inclined relative to that of the second arched channel 36. These directions intersect.

[0068] The pivoting flap 44 includes magnetic means 46 in the inlet passage 38. The magnetic means 46 are located between the first wall 28 and the second wall 30, outside the passages. This prevents the risk of short circuits and increases reliability. The magnetic means 46 comprise a permanent magnet or iron. The magnetic means 46 may be an insert embedded within the thickness of the pivoting flap 44. The magnetic means 46 form magnetic actuation means.

[0069] According to an alternative embodiment of the invention, the pivoting flap is a single-piece ferromagnetic body forming the magnetic means. The pivoting flap is then made of material.

[0070] The orienting module 22 includes a pivot joint 64 connecting the pivoting flap 44 to the guide body 32 in the inlet passage 38. This joint allows the pivoting flap 44 to be brought closer to the guide body 32, and thus shortens the orienting module 22. The pivot joint 64 is a mechanical joint with one degree of freedom. Here, it allows rotation about a transverse axis. The pivot joint 64 is located at a distance from the electromagnetic devices 50. At least one or each of the electromagnetic devices 50 includes an electrical coil. Depending on the flow direction 42, the magnetic means 46 are opposite the guide body 32 with respect to the pivot joint 64.

[0071] In the present embodiment, the pivot joint 64 has a horizontal pivot axis. However, the invention also considers a vertical pivot axis.

[0072] The pivoting flap 44 comprises a first thickness 66. The guide body 32 comprises a downstream expansion 68 with a second thickness 70, and an upstream plate 72 with a third thickness 74. The downstream expansion 68 forms a bulge on each upper and lower face of the guide body 32. The profile of the downstream expansion 68, combined with the shapes of the first wall 28 and the second wall 30, generates the Coanda effect. The third thickness 74 lies between the second thickness 70 and the first thickness 66. The second thickness 70 is the maximum thickness. The first thickness 66 and the third thickness 74 are average thicknesses. The second thickness 70 is at least twice, or at least three times, thicker than the first thickness 66. This helps to control pressure losses.

[0073] According to the flow direction 42, the guide body 32 comprises an upstream edge 76 and a downstream edge 78. They are opposite. They form edges. The pivoting flap 44 extends from the upstream edge 76. The pivot joint 64 is arranged at the upstream edge 76. This arrangement creates continuity between the pivoting flap 44 and the guide body 32, which limits pressure losses.

[0074] The guide body 32 comprises a first length 80 along the direction of flow. The pivoting flap 44 comprises a second length 82 greater than or equal to the first length 80. The upstream plate 72 comprises a third length shorter than the second length 82. These lengths optimize compactness. Furthermore, they allow the pivoting flap 44 to be lengthened and thus limit the angles in the extreme positions. This reduces turbulence, and therefore the noise level. The invention optimizes the perceived quality.

[0075] The electromagnetic device 50 is a source of magnetic field. The control unit 20 is configured to modulate the current supplying each electromagnetic device 50. This makes it possible to control the magnetic field in the housing 26, and in particular in the inlet passage 38. This aspect of the invention makes it possible to precisely control the angular orientation of the pivoting flap 44.

[0076] The housing 26 includes diffusion fins 84 connecting the guide body 32 to the first wall 28 and to the first wall 30. These fins are curved. The diffusion fins 84 pass through the first arched channel 34 and the second arched channel 36. The diffusion fins 84 form inclined scoops that force the airflow 24 to bifurcate in a predefined direction. The pivoting flap 44 is located at a distance from said diffusion fins 84. Each electromagnetic device 50 is also located at a distance from the diffusion fins 84. Thus, the presence of the magnetic actuation means does not interfere with the guidance provided by the diffusion fins 84.

[0077] According to an alternative embodiment of the invention, the pivoting flap comprises an elastic blade, for example made of elastomer. The elastic blade is rigidly connected to the guide body. She bends in order to gain first and second position.

[0078] Figure 4 shows a diagram of a manufacturing process for an airflow direction module for a motor vehicle. The motor vehicle may correspond to the one shown in relation to one of Figures 1 to 3.

[0079] The manufacturing process comprises the following steps:

[0080] a) supply of at least one electromagnetic device;

[0081] b) co-molding 102 of at least one electromagnetic device in at least one of the first wall and the second wall;

[0082] c) mounting 104 of the pivoting flap on the guide body; then optionally,

[0083] d) assembly 106 of the inlet element and the outlet element.

[0084] Step b) co-molding 102 allows the housing to be produced in one part or in two parts. During this step, the electromagnetic device is anchored to the associated wall. It forms an insert in the plastic mold. It becomes bonded or embedded in one of the walls. This facilitates manufacturing, improves compactness, and optimizes sealing.

[0085] In step c) assembly 104, the pivoting flap is connected to the guide body by means of the pivot joint. Step d) assembly 106 allows the magnetic means to be positioned relative to each electromagnetic device.

[0086] According to a preferred embodiment, the housing is made of a plastic or composite material. The plastic material may include a thermoplastic or thermosetting material. According to a preferred embodiment, the plastic material is selected from the group comprising polypropylene, polyamide, polyphthalamide, polyetheretherketone, polyphenylene sulfide, polyamide-imide, polyetherimide, polyarylamide, polyepoxide, unsaturated polyester, vinyl ester, or polyester-vinylester resins. For example, the composite material comprises a matrix of a plastic material as described above with reinforcement. For example, the reinforcement comprises glass or carbon fibers. The hinged flap may comprise at least one different material.

[0087] The casing comprises at least 10% by weight of recycled plastic material based on the total weight of the plastic material; preferably from 10 to 80% by weight; more preferably from 20 to 60% by weight or from 30 to 40% by weight. The use of recycled plastic material reduces the vehicle's environmental footprint.

[0088] The invention comprises the combination of all the embodiments illustrated by all the figures.

[0089] Figures 2 and 3 are isometric views. They each respect a specific scale, real angles and real proportions.
