Description

Title of the invention: Control device for controlled air intake of a motor vehicle

[0001] The invention relates to the modularity of components in a motor vehicle. The invention relates to the actuation of a controlled air intake in a motor vehicle. The invention relates to a control device for a controlled air intake in a motor vehicle. The invention also relates to a motor vehicle.

[0002] In order to optimize the aerodynamics of a motor vehicle, and thereby reduce primary energy consumption, controlled air intakes are installed on the front panels. A controlled air intake is operated between an open configuration in which an airflow enters the front compartment, and a closed configuration in which this same flow is limited or eliminated.

[0003] During operation, the airflow passing through the front compartment generates turbulence under the body as it exits said front compartment. This increases drag. A controlled air intake optimizes the deflected airflow during vehicle movement by adjusting the flow to the precise amount required. Controlling the proportion of airflow passing through the front compartment reduces primary energy consumption.

[0004] Document FR3006248B1 describes a controlled air intake module for mounting on the front of a motor vehicle to cool the coolant circulating in the vehicle's internal combustion engine. The module comprises movable flaps between a closed and an open position and means for controlling the movement of these flaps between these two positions. The module is mounted in such a position that, in the event of a pedestrian collision, it can absorb the impact of the pedestrian's femur. The module includes a peripheral frame comprising an upper cross member, a lower cross member, and two lateral uprights between which the movable flaps are mounted. The lower cross member and the two lateral uprights are made of a rigid material, and the upper cross member is made of a flexible material. This improves performance in the event of a pedestrian collision.

[0005] US patent 11247553B2 describes a device for closing a front-mounted, controlled air intake of a motor vehicle. The device includes a support frame in which a set of pivoting blades is installed. A control element for positioning the blades includes an actuator with mounting holes, a housing for the actuator, and a cover for the housing to enclose the actuator. The cover and housing are joined by a snap-fit ​​mechanism. The housing includes positioning fingers for insertion into the holes of actuator fixing, and the cover includes at least one specific shape which keeps the actuator fixed relative to the positioning elements when the cover is clipped onto the housing.

[0006] The positioning fingers and the internal shape of the cover constrain the shape of the actuator, so few models can be installed. Furthermore, this assembly is statically indeterminate. According to one option, the actuator's retention is improved by applying foam to the cover. However, using this foam adds a manufacturing step. Moreover, its durability remains limited.

[0007] The same controlled air intake device is intended to be fitted to different models of motor vehicles, and therefore to accommodate different actuators depending on the expected performance. These different actuators then have external housings with heterogeneous outer casings. Consequently, the support frame of the controlled air intake device must be adapted, or possibly modified. However, a modification of the support frame reduces the benefit of very large-scale production as intended in the automotive industry. There is therefore a need to improve the adaptability of a controlled air intake device. There is also a need to improve the retention of an actuator.

[0008] The invention aims to address at least one of the problems or drawbacks encountered in the prior art. In particular, the invention aims to improve the adaptability of a controlled air intake device for a motor vehicle.

[0044] 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 the control device 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 outwards and inwards towards the vehicle.

[0045] 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. The term "longitudinal" refers to the principal direction of travel of the vehicle. The term "transverse" refers to a direction perpendicular to the principal direction of travel of the vehicle.

[0046] The X-axis represents the longitudinal direction, the Y-axis represents the transverse direction, and the Z-axis represents the vertical direction of the motor vehicle. These three axes define a right-handed trihedron whose orientation is preserved throughout the figures.

[0047] In this description, the terms "vertical" and "horizontal" are not to be understood in their strict sense. 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.

[0048] In this description, the technical characteristics are defined in the mounting configuration of the control device, unless otherwise explicitly stated.

[0049] Throughout the description, the different figures use the same reference signs to designate identical or similar entities.

[0050] 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.

[0051] The motor vehicle 10 comprises a structure 12. The structure 12 forms an outer body, or a main frame of the motor vehicle. The structure 12 delimits different compartments of the motor vehicle 10, including the passenger compartment, the rear cargo area, and the front compartment (not shown).

[0052] The structure 12 connects various parts of the motor vehicle 10, including the openings. The structure 12 forms a mounting support for the powertrain, suspension systems, steering system, and braking systems. At the front, the structure 12 comprises at least one cross member 14, preferably two cross members 14, including an upper and a lower cross member. The cross members 14 are also referred to as transverse beams.

[0053] The motor vehicle 10 includes a controlled air inlet 18. The controlled air inlet 18, also called a controlled air inlet, draws air from the environment. It controls the inlet of an airflow used in a heat exchange. The controlled air inlet 18 is equipped with a control device 20. The control device 20 forms a flow control passage between the controlled air inlet 18 at the front of the motor vehicle and a cooling panel 24. The control device 20 forms a controlled air inlet module. The controlled air inlet 18 is advantageously a central and / or lower inlet. The cooling panel 24 contributes to the cooling of the vehicle passenger compartment and, optionally, to the cooling of an internal combustion engine.

[0054] The control device 20 is arranged vertically between the upper and lower crossmembers. In the event of a frontal impact, the shock absorber is affected. It plays a role in vehicle safety. It is flanked by shock absorbers against the crossmembers 14. The controlled air intake 18 is integrated into the bumper skin 22.

[0055] The motor vehicle can, for example, be a private motor vehicle or a commercial motor vehicle.

[0056] Figure [2] shows a motor vehicle control device 20. The motor vehicle may correspond to the one shown in relation to Figure [1].

[0057] The control device 20 includes a support frame 26. The support frame 26 forms the periphery of the control device 20. It forms the general framework of the control device 20. The support frame 26 includes vertical uprights 28 and horizontal uprights 30. The horizontal uprights 30 run alongside the crossbeams 14. The horizontal uprights 30 are supported against the crossbeams 14 in order to position and hold the control device 20.

[0058] The regulating device 20 comprises at least one longitudinal passage 32, in this case two longitudinal passages 32. They are transversely separated. Each longitudinal passage 32 crosses longitudinally the support frame 26. The longitudinal passage 32 is transversely split.

[0059] The regulating device 20 comprises at least one shuttering blade 34. Each shuttering blade 34 is movable between an open position and a closed position in the associated longitudinal passage 32. Each shuttering blade 34 blocks the longitudinal passage 32 or the associated portion of the longitudinal passage 32.

[0060] Each sealing blade 34 is rotatable about a transverse axis of rotation. It is capable of occupying intermediate positions between the open and closed positions. Thus, the regulating device 20 allows control of airflow through each longitudinal passage 32. In the closed position, the sealing blades 34 are joined together. They overlap.

[0061] The shutter blades 34 are arranged in several sets. They comprise a first set 36 of shutter blades 34 and a second set 38 of shutter blades 34. These sets can be a left set and a right set. This improves the vertical compactness of the regulating device 20. Each shutter blade 34 forms a strip. It includes a lower half with a pivot joint that allows it to pivot relative to the support frame 26. The lower half is considered when the shutter blade 34 is in the closed position, for example, vertical. The shutter blades 34 in the same set are mechanically coupled by a rod or a series of gears.

[0062] The regulating device 20 includes transmission means 40. The transmission means 40 are coupled to the shutter blades 34. The transmission means 40 connect the first set 36 and the second set 38. The transmission means 40 include a rotation axis, for example, a transverse axis. The transmission means 40 include, for example, a splined spindle. The transmission means 40 are split into two parts to facilitate assembly.

[0063] The control device 20 includes a mounting area 42. The mounting area 42 may be a central area. The control device 20 includes a front face and a rear face 44. The mounting area 42 is arranged on the rear face 44. The mounting area 42 forms an open pocket on the rear face. It is surrounded by the support frame 26. The mounting area 42 accommodates an actuator 46. The actuator 46 is a motor. It is electrically powered and controls the position of the shutter blades 34. The transmission means 40 extend from at least one shutter blade 34 to the mounting area 42. The transmission means 40 are capable of transmitting torque from the actuator 46 to the shutter blades 34. The transmission means 40 pass through the actuator 46.

[0064] The actuator 46, but also the mounting area 42, is placed between the two sets of shutter blades 34. The actuator 46 is configured to move each shutter blade 34 between the closed position, as shown on the left; and an open position, as shown on the right.

[0065] Generally, the support frame 26 includes elastic means 48 configured to retain the actuator 46. The elastic means 48 are configured to exert a holding force against the actuator 46. They are arranged in, or at the boundary of, the mounting area 42.

[0066] According to an alternative of the invention, the regulating device comprises a single set of shutter blades. They form a single stack.

[0067] Figure 3 shows a motor vehicle control device 20. The motor vehicle may correspond to the one shown in relation to one of Figures 1 to 2. The actuator is not shown for clarity.

[0068] The elastic means 48 include an elastic arm 50. The elastic arm 50 is adapted to come into contact with the actuator and push it in a certain direction, towards a predefined position. It is arranged in the mounting area 42. The elastic arm 50 is arranged within the functional volume of the mounting area 42. In the mounting area 42, the support frame thus presents an elastic arm 50 designed to cooperate with the actuator so as to maintain said actuator within the mounting area 42.

[0069] The mounting area 42, or more generally the support frame 26, includes a stud 52 projecting longitudinally. The stud 52 extends rearward. The elastic arm 50 is connected to the stud 52. It extends transversely from said stud 52.

[0070] The support frame 26 includes an upper cavity 54 communicating with the mounting area 42. The upper cavity 54 is open downwards. It is on the rear face. The upper cavity 54 includes a first transverse stop surface 56. The first transverse stop surface 56 is transversely opposite the elastic arm 50. It is intended to cooperate with the actuator in order to lock and position it transversely.

[0071] The support frame 26 includes a lower positioning loop 58. The lower positioning loop 58 is located in the lower part of, or below, the mounting area 42. It projects rearward. The lower positioning loop 58 includes a second transverse stop surface 60 transversely opposite the elastic arm 50. The second transverse stop surface 60 is intended to cooperate with the actuator to ensure transverse positioning. The transverse stop surfaces are oriented in the same direction.

[0072] The lower positioning loop 58 extends longitudinally along the mounting area 42. It protrudes longitudinally. The lower positioning loop 58 overlaps longitudinally the elastic arm 50. The lower positioning loop 58 is vertically spaced from the elastic arm 50. The elastic arm 50 is vertically positioned between the first transverse stop surface 56 and the second transverse stop surface 60.

[0073] The first transverse stop surface 56 and the second transverse stop surface 60 extend vertically and longitudinally. According to an alternative embodiment of the invention, the first transverse stop surface and the second stop surface transverse are horizontal, the elastic branch being able to push the actuator vertically towards these transverse stop surfaces.

[0074] According to an alternative embodiment of the invention, the mounting area includes at least one actuator mounting hook. The elastic arm is configured to push the actuator towards said hook.

[0075] Figure 4 shows the rear face 44 of a control device 20 for a regulated air intake of a motor vehicle. The motor vehicle may correspond to the one shown in relation to one of Figures 1 to 3. In this illustration, the shutter blades 34 are shown in the closed position. They are vertical. The actuator is not shown for clarity.

[0076] The elastic arm 50 is configured to exert a holding force on the actuator to hold it in the mounting area 42. The elastic arm 50 is configured to exert a horizontal holding force on the actuator from the first set 36 to the second set 38 of shutter blades 34.

[0077] The elastic arm 50 protrudes into the mounting area 42. The elastic arm 50 is transversely movable. It is capable of generating a transverse holding force. The mounting area 42 includes a stud 52 that protrudes longitudinally. The stud 52 is essentially hollow. The support frame 26 includes a through opening 62. The through opening 62 leads to the elastic arm 50. It is delimited by the elastic arm 50. The through opening 62 passes through the stud 52. This arrangement increases the flexibility of the elastic arm 50 and extends its potential travel.

[0078] The support frame 26 includes a retaining hole 64. The actuator preferably includes a retaining hook adapted to cooperate with the retaining hole 64 to ensure longitudinal retention. The retaining hole 64 is preferably formed on an elastic tab 66. The elastic tab 66 allows displacement of the retaining hole 64 when the actuator is held. The elastic arm 50 is longitudinally opposite the retaining hole 64 with respect to the transmission means 40.

[0079] Figure 5 shows a control device 20 for a controlled air intake of a motor vehicle. The motor vehicle may correspond to the one shown in relation to one of Figures 1 to 4. The support frame 26 is made of a single piece of material. It is preferably made by molding.

[0080] In the mounting area 42, the support frame 26 includes an elastic arm 50 cooperating with the actuator 46 so as to maintain said actuator 46 in the mounting area 42. The actuator 46 includes an outer housing forming a main body. It forms a central body. It encloses a mechanism and an electric motor. It is preferably sealed. The actuator 46 includes a lateral side 16 against The elastic branch 50. The lateral flank 16 extends longitudinally and vertically. The elastic branch 50 is at a distance from the longitudinal passage(s) 32.

[0081] The actuator 46 comprises a first projection 68 against the first transverse stop surface 56, and a second projection 70 against the second transverse stop surface 60. These projections are respectively an upper projection and a lower projection. They extend from the outer housing, preferably vertically. They comprise positioning surfaces complementary to the transverse stop surfaces.

[0082] Thus, the presence of the elastic arm 50, or more generally the elastic means 48, improves the retention of the actuator 46. This solution limits any potential vibrations of the actuator 46 within the support frame 26. Furthermore, it allows the use of actuators with variable widths. Indeed, the elastic arm 50 compensates for this variation. Housings of varying widths can be used. Consequently, actuators of varying power can be selected. The invention optimizes manufacturing since the elastic arm is added to the support frame 26.

[0083] The actuator 46 has an electrical connection port 72. The motor vehicle includes an electrical network with a plug for connection to the electrical connection port 72. The electrical network is controlled by a control unit, such as the vehicle's on-board computer or a specific computer module. The electrical connection port 72 is positioned at the bottom to limit the effects of humidity. The elastic arm 50 is vertically positioned away from the electrical connection port 72.

[0084] The transmission means 40 are configured to connect the shutter blades 34 to the actuator 46. The transmission means 40 include a rotation axis 74. The rotation axis 74 is horizontal and transverse. The elastic arm 50 is configured to generate a positioning force oriented along said rotation axis 74. The rotation axis 74 is parallel to that of the shutter blades 34.

[0085] According to an alternative embodiment of the invention, the actuator comprises a telescopic cylinder. The cylinder is connected to a connecting rod of a shutter blade.

[0086] Figure 6 illustrates a cross-section of a motor vehicle control device 20. The motor vehicle may correspond to the one shown in relation to one of Figures 1 to 5. The through opening 62 bypasses the elastic arm 50. It passes through the stud 52.

[0087] The elastic arm 50 extends longitudinally from the stud 52. It extends it transversely. It points forward. The elastic arm 50 is transversely movable. By adding the elastic arm 50 to the stud 52, the latter becomes an elastic pad. It allows the actuator 46 to be stopped while adapting to the variable width of the latter depending on the model used.

[0088] The elastic arm 50 comprises a length, preferably a longitudinal length, of between 10 mm and 70 mm, more preferably between 15 mm and 50 mm. These length ranges optimize elasticity and compactness.

[0089] The elastic arm 50 comprises a first end 76 connected to the stud 52, and a second end 78 longitudinally opposite the first end 76. The second end 78 comprises a contact surface 80 cooperating with the actuator 46 to hold it in position. The contact surface 80 extends vertically and longitudinally. The contact surface 80 is parallel to the first transverse stop surface and / or the second transverse stop surface.

[0090] The elastic arm 50 is able to deform when the actuator 46 is placed in the mounting area 42. A part of the elastic arm 50 normally present in the volume occupied by the actuator 46 is shown in dashed lines.

[0091] The support frame 26 includes a front panel 82 delimiting the mounting area 42. The front panel 82 is a front wall. It extends vertically and transversely. The stud 52 projects from the front panel 82. The front panel 82 is inclined with respect to the vertical direction, for example at an angle between 10° and 45°. This inclination facilitates electrical connection and maintains compactness.

[0092] The front wall 82 includes an elastic boss 84 projecting longitudinally towards the elastic arm 50. The elastic boss 84 is intended to retain the actuator 46 longitudinally. The elastic boss 84 is capable of compressing longitudinally when the actuator 46 is put in place. It then generates a longitudinal holding force.

[0093] The characteristics described in relation to the elastic branch generally apply to elastic means.

[0094] According to a preferred embodiment, the support frame 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.

[0095] The support frame 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; Preferably, 20 to 60% by weight or 30 to 40% by weight. The use of recycled plastic material reduces the vehicle's environmental footprint.

[0096] The invention comprises the combination of all the embodiments illustrated by all the figures.

[0097] Figures 2 to 6 are isometric views. They each respect a specific scale, real angles and real proportions.
