Description

Ventilator for vehicle and vehicle

Technical Field

The present invention relates to a ventilator for a vehicle, and to a vehicle.

Background

The ventilator comprises an orientable deflector member to direct the air flow exiting the duct of the ventilator. Each orientable deflector member is generally formed by a blade comprising two guiding surfaces for the air. The space between the two opposite air guiding surfaces of two adjacent vanes forms a passage section for the air leaving the ventilator.

Typically, the orientation of the blades is controlled by levers mechanically connected to each blade.

The control rod is typically mounted inside and movable relative to the duct of the ventilator. Translation of the control rod on the pipe causes all the blades to rotate simultaneously.

A link is mounted at an outer edge of each blade to connect each blade to the lever, thus reducing a guide surface for air. The control rod is fixed to the connecting rod of each blade and thus passes through the passage section of the air. This reduces the air passage section and thus increases the pressure loss, thereby reducing the efficiency of the ventilator.

To limit pressure losses, the control rod may be mounted to the outside of the ventilator's ducting. The control rods are connected to the blades by means of links fixed to the top of each blade. A cavity in the upper surface of the duct of the ventilator allows passage of the linkage rod and displacement of the linkage rod as the control rod translates.

However, the presence of these cavities can lead to a loss of tightness of the ducts of the ventilator. This may lead to air leakage and noise problems.

Furthermore, new functions installed on the dashboard of a motor vehicle, such as installing larger and larger screens, take up more and more space. As a result, ventilation systems are increasingly being limited. However, mounting the control rod outside the duct also has the disadvantage of taking up space.

SUMMERY OF THE UTILITY MODEL

The aim of the utility model is to provide a solution for controlling adjustable vanes of a ventilator of a vehicle that allows to reduce pressure losses while ensuring good tightness of the ducts of the ventilator and while maintaining the economy of the setup.

To this end, the utility model relates to a ventilator for a vehicle, comprising: at least one orientable deflector member to direct the flow of air exiting the ventilator in a desired direction; and a control device for controlling the orientation of the orientable deflector member, the control device comprising a control rod, wherein one of the orientable deflector member or the rod comprises at least one magnet and the other of the orientable deflector member or the rod comprises at least one metal insert, the magnet being positioned substantially facing the metal insert such that displacement of the control rod changes the orientation of the orientable deflector member by magnetic cooperation between the magnet and the insert.

In the case where at least one magnet and a metal insert are mounted facing each other on the control rod and the orientable deflector member, the control rod and the orientable deflector member are not mechanically connected and the orientation of the member is achieved by magnetic cooperation between the rod and the orientable deflector member.

Thus, the control rod may be mounted outside the duct, so that it is not necessary to form a cavity in the duct. The sealing performance of the ventilator is ensured.

Furthermore, no control member extends into the duct, which minimizes pressure losses and provides optimal efficiency of the ventilator.

The ventilator according to the utility model may comprise one or more of the following features, which may be adopted alone or in any technically possible combination:

-displacement of the control rod gradually changes the orientation of the orientable deflector member between the two maximum positions.

-said orientable deflector member extends in a duct defining an inlet surface of said air flow and an outlet surface of said air flow, said control rod being mounted so as to be displaceable on said duct.

-the control rod is mounted so as to be able to translate on the pipe in a direction substantially perpendicular to the longitudinal axis of the pipe.

-said orientable deflector member is mounted so as to be able to move in rotation in said duct, the translational displacement of said control rod on said duct causing a rotational displacement of said orientable deflector member.

-the axis of rotation of the orientable deflector member is substantially perpendicular to the longitudinal axis of the duct and to the direction of translation of the control rod on the duct.

-said orientable deflector member is formed by a blade comprising two guide surfaces for air, said metal insert extending on the edge of said blade joining said two guide surfaces.

-the ventilator comprises at least two orientable deflector members, each comprising at least one metal insert, respectively comprising at least one magnet; and said control rod comprising at least two magnets, respectively at least two metal inserts, each magnet being placed substantially facing a metal insert, the displacement of said orientable deflector member being synchronized by said control rod.

-the number of magnets is equal to the number of orientable deflector members.

The utility model also relates to a vehicle comprising a ventilator as described above for a vehicle.

Detailed Description

The ventilator 2 shown in fig. 1 is, for example, a ventilator of a vehicle, in particular of a motor vehicle.

The ventilator 2 is configured to discharge an air flow f from a ventilation system of the vehicle, for example into a passenger compartment of the vehicle. The ventilator 2 comprises a duct 4 for the passage of the air flow F and at least one orientable deflector member 6, the orientation of which 6, controlled by a control lever 8, allows to guide the air flow F away from the ventilator 2.

The duct 4 defines an air inlet 10 through which the air flow F enters the ventilator 2 and an air outlet 12 through which the air flow F exits the ventilator 2. The inlet 10 is thus connected to the ventilation system of the vehicle and the air outlet 12 opens, for example, into the passenger compartment of the vehicle, for example into a decorative element of the passenger compartment (e.g. dashboard, center console, door panel, etc.). The duct 4 is delimited by one or more walls. When the duct 4 is bounded by a wall, its cross-section is, for example, circular or oval. When the duct 4 is delimited by four walls, as shown in the figures, it has a rectangular or square cross-section, for example.

The duct 4 extends along a longitudinal axis a between an air inlet 10 and outlet air 12. The direction of the air flow f entering the duct is substantially parallel to the longitudinal axis a of the duct 4 and perpendicular to a transverse axis B of the duct 4, which is substantially perpendicular to the wall or opposite wall of the duct 4.

The orientable deflector member 6 is mounted to pivot about a rotation axis C. According to one embodiment, the ventilator 2 comprises a plurality of deflector members distributed in the duct 4. Thus, according to this embodiment, the ventilator 2 comprises at least two deflector members 6. The orientable deflector member 6 is mounted to pivot about a rotation axis C parallel to each other. The deflector members 6 are regularly distributed alongside one another in the duct, for example in the transverse direction B. The distance between two adjacent deflector members 6 is for example between 5 and 20 mm.

Each orientable deflector member 6 is for example in the form of an orientable blade. The rotation axis C extends, for example, along one of the lateral edges 7 of the blade or between two opposite lateral edges 7 of the blade, in particular near the centre of the blade.

Each orientable deflector member 6 extends from one wall of the duct 4 to the opposite wall of the duct 4 with its axis of rotation C substantially perpendicular to the longitudinal axis a of the duct 4.

Preferably, the orientable deflector member 6 is mounted inside the duct 4, in proximity to the air outlet; the rotation axes C are perpendicular to the transverse axis B of the duct 4 and are distributed along the transverse axis B of the duct 4. As a variant, the axis of rotation of the orientable deflector member 6 is parallel to the transverse axis B of the duct 4 and is distributed in a direction perpendicular to the transverse axis B and to the longitudinal axis a of the duct 4.

The two opposite faces of each orientable deflector member 6 each define a guide surface 14 for the air flow F through the duct 4. That is, the air flow leaving the ventilator is oriented substantially along the plane in which the guide surface 14 extends. Thus, by changing the orientation of the deflector member 6 in the duct 4, the orientation of the air flow F leaving the ventilator is changed. The space between the two guide surfaces 14 of two adjacent orientable deflector members 6 thus forms a passage section 16 which guides the air flow F in the desired direction.

A metal insert 18 is mounted on each orientable deflector member 6. The metal insert 18 is for example glued or clamped onto the deflector member 6 or overmoulded by the deflector member 6.

As shown in fig. 3, the metal insert 18 extends, for example, on an upper edge 20 of the orientable deflector member 6 that joins the two guide surfaces 14. As shown in fig. 3, the upper edge 20 extends, for example, substantially perpendicular to the edge 7 along which the rotation axis C extends. The metal insert 18 extends in the vicinity of the lateral edge 7 of the blade opposite to the edge 7 along which the rotation axis C extends. For a rotation axis C extending between the lateral edges of the blade, the metal insert is positioned at a distance from the rotation axis C to create a lever arm effect.

As a variant, the metal insert 18 extends, for example, on the lower edge of the orientable deflector member 6.

As a variant, according to another embodiment, the metal insert 18 extends on a lateral edge of the orientable deflector member 6, in particular when the rotation axis of the orientable deflector member 6 is parallel to the transversal axis B of the duct 4. The metal insert 18 is thus positioned adjacent the upper wall 22 of the pipe 4 and spaced from the axis of rotation C such that displacement of the metal insert 18 causes rotation of the deflector member 6. The inserts 18 of the different deflector members 6 are aligned substantially in the transverse direction.

The control rod 8 is mounted to be movable on the pipe 4 and in particular on the upper wall 22 of the pipe 4, as shown in fig. 2. The control rod 8 extends facing the metal insert 18 of the deflector member such that the control rod 8 and the metal insert 18 extend on both sides of the upper wall 22.

As shown in fig. 1, the control rod 8 is rectilinear and extends along an axis D. In particular, the control rod 8 extends along an axis D perpendicular to the rotation axis C of each orientable deflector member 6 and to the longitudinal axis a of the duct 4.

According to one embodiment, the axis D is parallel to the transverse direction B. According to the second embodiment, the axis D is perpendicular to the transverse axis B.

The control rod 8 is preferably mounted outside the duct 4.

The control rod 8 is mounted to be slidable along its axis D, the sliding of the control rod 8 along the axis D controlling the orientation of the steerable deflector member 6, as will now be described.

The control rod 8 comprises at least one magnet 24. More specifically, the control rod 8 comprises as many magnets 24 as the deflector member 6 and therefore as the metal insert 18. The magnets are then regularly distributed on the control rod 8, for example along the axis D. Each magnet 24 is for example glued or clamped onto the control rod 8 or overmoulded by the control rod 8.

The distance between two adjacent magnets 24 is for example between 3 and 20 mm.

The magnets 24 are positioned such that each metal insert 18 of the orientable deflector member 6 is located in the magnetic field of the magnets 24. Thus, as shown in fig. 2, each magnet 24 is preferably placed substantially facing the metal insert 18 of the orientable deflector member 6 in a direction substantially parallel to axis C. Thus, according to this embodiment, the distance separating two adjacent magnets 24 is substantially equal to the distance separating the axes of rotation C of two adjacent deflector members. The magnetic field of the magnet 24 is arranged to cause a displacement of the corresponding metal insert 18 when the magnet 24 is displaced, which allows orienting the orientable deflector member 6 by displacing the magnet 24.

The distance between the magnet 24 and the corresponding metal insert 18 is for example between 1 and 5mm, preferably between 1.5 and 3 mm. This distance includes the thickness of the upper wall 22 of the pipe 4 and the operating clearance. The upper wall 22 of the duct 4 has a thickness of, for example, between 1.2 and 2.5 mm.

As shown in fig. 1 and 2, translation of the control rod 8 in a first direction along the axis D causes displacement of the magnets 24 and, due to the displacement of the magnetic field of each magnet 24 in the first direction, rotation of the deflector member 6 about its axis of rotation C in that first direction. Each metal insert 18 is therefore attracted in a first direction by the magnetic field of the corresponding magnet 24, causing each deflector member 6 to pivot along axis C and thus to be oriented in the first direction. The orientation of the deflector member 6 is thus achieved by the magnetic cooperation between the magnet 24 and the metal insert 18, without a mechanical connection between the deflector member 6 and the control rod 8.

By translation of the control rod 8 in the first direction, a single movement of the deflector member 6 in the first direction is induced. Thus, the displacement of the deflector member 6 is synchronized by the control rod 8.

The orientation of the deflector member 6 in the first direction causes a change in the shape of the channel section 16.

The air flow F entering through the air inlet 10 perpendicularly to the transverse axis B of the duct 4 is then directed inside the channel section 16 and in a first direction, as indicated by the arrow F in fig. 1. The air flow F exiting the duct 4 through the air inlet 10 is oriented in a direction forming an angle θ with the longitudinal axis a, this angle being between 90 ° and 0 °. The orientation angle θ is defined as the angle between the exit direction of the air flow F and the longitudinal axis a.

Likewise, as shown in fig. 5, translation of the control rod 8 along the axis D in a second direction opposite the first direction causes the deflector member 6 to pivot in the second direction. The air flow F exiting the duct 4 through the air outlet 12 is oriented in a direction forming an angle θ with the longitudinal axis a, this angle being comprised between 0 ° and-90 °.

Fig. 1 shows a first extreme position of the control rod 8. The angle theta between the direction of the air flow F and the longitudinal axis a reaches its maximum here.

Fig. 5 shows the second extreme position of the control lever 8. The angle theta between the direction of the air flow F and the longitudinal axis a reaches its minimum here.

By means of a gradual translation of the control rod 8 in a first direction or in a second direction opposite to the first, the angle θ can take any value between its maximum value represented in fig. 1 and its minimum value represented in fig. 5.

For example, fig. 2 and 4 show a central position of the orientable deflector member 6. The angle theta is zero. Thus, the air flow F leaves the duct 4 in the same direction as the incoming air flow F.

By means of the utility model, the orientation of each orientable deflector member 6 is controlled by translation of the control rod 8. As the control rod 8 translates, the magnet 24 placed on the control rod attracts the metal insert 18 placed on the orientable deflector member 6 through the magnetic field, forcing the orientable deflector member to pivot in the direction of translation.

The control of the orientation of the orientable deflector member 6 is thus achieved without mechanical connection and without the passage section 16 obstructing the air flow F.

Therefore, the pressure loss is reduced and the sealability of the pipe 4 is ensured. The present invention thus provides the advantage of improving the efficiency of the ventilator 2.

As shown, the first and second directions are, for example, left-right directions, so as to direct the air flow along the width of the passenger compartment of the vehicle. In this embodiment, the axis of rotation C of the deflector member 6 is perpendicular to the transverse axis B of the conduit 4.

As a variant, the first and second directions are, for example, up and down directions, so as to direct the air flow along the height of the passenger compartment. In this embodiment, the axis of rotation C of the deflector member 6 is parallel to the transverse axis B of the conduit 4.

According to one embodiment, the ventilator comprises two sets of deflector members 6, these deflector members 6 being perpendicular to each other and extending downstream in the direction of the air flow in the vicinity of the outlet of the duct. For example, a first group allows for orienting the air flow to the left or right, while a second group allows for orienting the air flow up or down. The second control rod 8 controlling the second set of deflector members 6 is thus positioned movable on one of the lateral faces of the pipe 4 facing the second set of deflector members 6.

The displacement of the one or more control rods 8 may be controlled mechanically by means of one or more buttons located on the front of the ventilator and accessible by the user or may be controlled electronically.

According to another embodiment of the utility model, the metal insert 18 is mounted on the control rod 8, while the magnet 24 is mounted on the deflector member 6. The structure and operation of the ventilator 2 according to the present embodiment is the same as that described above, except for this inversion.
