Description

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

[0001] The invention relates to ventilation systems for a motor vehicle. The invention relates to the orientation of an air flow at the outlet of a ventilation duct in a motor vehicle passenger compartment. The invention relates more specifically to an air flow orientation 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 air flow orientation module for a motor vehicle.

[0002] Vehicles conventionally have vents arranged in their passenger compartments, the role of which is to introduce air-conditioned air into the passenger compartment of the vehicle. The vents are, for example, installed on a dashboard of the vehicle. It is also known to produce an vent in which the direction of the outgoing air flow is modified using the Coanda effect. The Coanda effect corresponds to the tendency of a moving fluid to follow convex surfaces. Thanks to this effect, it is possible to guide the outlet flow by distributing the flow between different corridors having particular surface geometries, inside the vent.This makes it possible to manage the direction of the air flow at the vent outlet without using movable guide vanes, and to reduce the visible section of the vent without reducing performance: for example, by using the Coanda effect to manage the vertical direction of the air flow, the visible section of the vent along this vertical axis can be reduced.

[0003] However, a passenger compartment air circulation system is not limited to the visible part of an aerator. Said system also comprises a system for producing air conditioning in order to supply air at the desired temperature to the passenger compartment, as well as air guide channels and ducts in order to bring the latter from the air conditioning production system to the aerators distributed in the passenger compartment.

[0004] In order to guarantee an optimal level of comfort for the occupants of the passenger compartment, in particular from the aeraulic and sound point of view, it is necessary to avoid pressure losses in the air flow as well as ventilation noise. In particular, in order to fully benefit from the advantages linked to the use of the Coanda effect in the design of an air circulation system, the flow of the latter in said system must remain as laminar as possible. The junctions between the different ducts and air guide sections may have defects which disrupt the laminar flow of the air flows and generate noise and pressure losses.

[0032] Each characteristic introduced by the expression “preferably” given in relation to one of the aspects of the invention applies to all the other aspects of the invention.

[0033] The invention will be well understood and other aspects and advantages will appear clearly on reading the following description, given with reference to the appended figures and listed below.

[0036] [Fig. 3] shows a section of an air flow orientation module in a motor vehicle passenger compartment according to the invention.

[0037] [Fig.4] is a diagram of a method of manufacturing a motor vehicle according to the invention.

[0038] In the following description, the term "comprise" is synonymous with "include" and is not limiting in that it allows the presence of other elements in the motor vehicle or other steps in the method to which it relates. It is understood that the term "comprise" includes the terms "consist of". The terms "external" and "internal" will designate respectively that which is oriented towards the outside of the vehicle and towards the inside of the vehicle.

[0039] In the present description, the term "longitudinal", the term "longitudinally", the term "transverse", and the term "transversely" are used according to the reference frame of the vehicle, in the mounting configuration. The term "longitudinal" corresponds to the main direction of movement of the vehicle. The term "transverse" corresponds to a direction perpendicular to the main direction of movement of the vehicle. The term "front" refers to the main direction of movement of the vehicle. The term "rear" designates the opposite of the front of the vehicle.

[0042] In the present description, the equalities between the values ​​are not to be understood in the strict sense insofar as each equality authorizes a variation of at most 10%, preferably at most 5%, more preferably at most 2%, between these values.

[0043] In the present description, the term "vertical" and the term "horizontal" are not to be understood in the strict sense of the term. Indeed, they allow an inclination of at most 20°, preferably at most 10°, more preferably at most 5°, even more preferably at most 2°; compared to the strict sense of these terms.

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

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

[0046] [Fig.l] 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 comprises 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 giving access to the passenger compartment 14 or to other compartments. In the front part, the passenger compartment 14 is delimited by a dashboard 16. The dashboard 16 extends transversely over the entire width of the passenger compartment 14. It accommodates various control members of the motor vehicle, as well as display devices.

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

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

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

[0051] [Fig.2] shows an air flow 24 orientation module 22 for the passenger compartment passenger 14 of a motor vehicle. The motor vehicle may correspond to that 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 housing different members, different parts. It materializes a distribution duct guiding the air flow 24 passing 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 envelope of the housing 26. They are sealed. The housing 26 also comprises a guide body 32 for the air flow 24 flowing between the first wall 28 and the second wall 30. The guide body 32 forms an ogive. 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 arcuate channel 34 from a second arcuate channel 36. The first arcuate channel 34 is delimited by the first wall 28 and the guide body 32, while the second arcuate channel 36 is delimited 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 arcuate channel 34 is inclined relative to the second arcuate channel 36. Downstream, they converge in the outlet passage 40. The housing 26 defines a flow direction 42.

[0055] The inlet passage 38 comprises 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 make it possible to control, to modulate proportions of airflow 24 passing through the first arcuate channel 34 and the second arcuate channel 36. Since the channels are inclined, this aspect makes it possible to control the general direction of exit of the airflow.

[0056] The pivoting flap 44 forms a plate. It comprises magnetic means 46 in the inlet passage 38. The magnetic means 46 are 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, comprises 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 movable part of the magnetic actuator of the pivoting flap 44 directly in the inlet passage 38. This avoids piercing the first wall 28 or the second wall 30, which would be likely to generate leaks, and therefore a loss of efficiency. The actuation force is exerted through the walls. This aspect also facilitates manufacturing, and reduces the number of parts to be assembled.

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

[0060] The housing 26 comprises an input element 54 and an output element 56 fixed to the input element 54. They form two sleeves. For example, they are fixed in a longitudinal assembly movement. The pivoting flap 44 is connected to the output element 56. It is integral with the output element 56. The or each electromagnetic device 50 is connected to the input element 54. The input element 54 carries each electromagnetic device 50. For example, the input element 54 forms and delimits the input passage 38. For example, the output element 56 forms the output passage 40.

[0061] The input element 54 comprises a fixing edge 58 to the output element 56. The fixing edge 58 forms a loop surrounding the output element 56. It comprises fixing tabs and / or fixing holes. Each electromagnetic device 50 is at a distance from said fixing edge 58. This aspect facilitates the installation of the fixing means. The production in several elements facilitates their molding, and facilitates the assembly of the pivoting shutter.

[0062] The electromagnetic device 50 is a first electromagnetic device 60 against the first wall 28. The second wall 30 comprises a second electromagnetic device 62. The second electromagnetic device 62 is adapted to generate 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. Each electromagnetic device 50 is adapted to attract or repel the pivoting flap 44 via its magnetic means 46. They are functionally identical. The magnetic means 46 are 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 hold the pivoting shutter 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] [Fig. 3] shows a section of a module 22 for directing air flow 24 blown into a passenger compartment of a motor vehicle. The motor vehicle may correspond to that presented in relation to one of FIGS. 1 to 2.

[0066] The inlet passage 38 houses a pivoting flap 44 in the housing 26. The pivoting flap 44 is able to swing by tilting from a first position (shown in dotted lines at the top) against the first wall 28 to a second position (shown in dotted lines at the bottom) against the second wall 30. The pivoting flap 44 is also able to occupy a central position (shown 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 make it possible to share the air flow 24 between the first arcuate channel 34 and the second arcuate channel 36. The first arcuate channel 34 comprises an outlet direction which is inclined relative to that of the second arcuate channel 36. These directions intersect.

[0068] The pivoting flap 44 comprises magnetic means 46 in the inlet passage 38. The magnetic means 46 are between the first wall 28 and the second wall 30; outside the passages. This avoids 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 in the thickness of the pivoting flap 44. The magnetic means 46 form magnetic actuation means.

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

[0070] The orientation module 22 comprises a pivot connection 64 connecting the pivoting flap 44 to the guide body 32 in the inlet passage 38. This articulation makes it possible to bring the pivoting flap 44 closer to the guide body 32, and therefore to shorten the orientation module 22. The pivot connection 64 is a mechanical connection with one degree of freedom. Here, it allows rotation along a transverse axis. The pivot connection 64 is at a distance from the electromagnetic devices 50. At least one or each electromagnetic device 50 comprises an electric coil. According to the flow direction 42, the magnetic means 46 are opposite the guide body 32 relative to the pivot connection 64.

[0071] In the present embodiment, the pivot link 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 widening 68 with a second thickness 70, an upstream plate 72 with a third thickness 74. The downstream widening 68 forms a bump on each upper and lower face of the guide body 32. The profile of the downstream widening 68 coupled with the shapes of the first wall 28 and the second wall 30 makes it possible to generate the “Coanda” effect. The third thickness 74 is between the second thickness 70 and the first thickness 66. The second thickness 70 is a 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 makes it possible to control the 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 connection 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 in 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 less than the second length 82. These lengths optimize compactness. In addition, they make it possible to lengthen the pivoting flap 44 and therefore to limit the angles in the extreme positions. This reduces turbulence, and thus the noise level. The invention optimizes the perceived quality.

[0075] The electromagnetic device 50 is a magnetic field source. 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 comprises diffusion fins 84 connecting the guide body 32 to the first wall 28 as well as to the first wall 30. They are curved. The diffusion fins 84 pass through the first arcuate channel 34 and the second arcuate channel 36. The diffusion fins 84 form inclined scoops imposing a bifurcation on the air flow 24 in a predefined direction. The pivoting flap 44 is at a distance from said diffusion fins 84. Each electromagnetic device 50 is at a distance from the diffusion fins 84. Thus, the presence of the magnetic actuation means does not disturb the guidance provided by the diffusion fins 84.

[0077] According to an alternative of the invention, the pivoting shutter 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 position and second position.

[0078] [Fig.4] shows a diagram of a manufacturing process for an air flow orientation module for a motor vehicle. The motor vehicle may correspond to that shown in relation to one of Figures 1 to 3.

[0079] The manufacturing process comprises the steps:

[0080] a) providing 100 at least one electromagnetic device;

[0081] b) co-molding 102 of the 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 input element and the output element.

[0084] Step b) co-molding 102 makes it possible to produce the housing in one element, or in two elements. During this step, the electromagnetic device is anchored to the associated wall. It forms an insert in the plastics mold. It becomes glued 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 connection. Step d) assembly 106 makes it possible to position the magnetic means 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 comprise a thermoplastic material or a 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-vinyl ester resins. For example, the composite material comprises a matrix of a plastic material as described above with a reinforcement. For example, the reinforcement comprises glass or carbon fibers. The pivoting flap may comprise at least one different material.

[0087] The housing 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 ecological footprint of the vehicle.

[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.
