Definitions
- the present invention relates to shutter devices and more specifically to a shutter device for front air intake of a motor vehicle.
- the front faces of motor vehicles are generally composed of two main air inlets called high and low track, separated by a bumper beam. Behind this bumper beam are generally placed the heat exchangers of the motor vehicle, such as that used for the air conditioning of the passenger compartment and / or that used for cooling the engine.
- a support frame comprising a multitude of flaps mounted pivoting about parallel axes and adapted to take a multitude of different angular positions, between an open position and a closed position, under the action of appropriate control means.
- This provides a shutter device similar to a jalousie that adjusts the air flow through the air inlets and arriving at the heat exchangers. It is thus possible to optimize the efficiency of these heat exchangers as needed and by varying the amount of air they receive. In addition, at high speed, shutters in the closed position reduce the drag coefficient of the vehicle and thus improve the aerodynamics of said vehicle.
- the device allowing the passage of a closed position to an open position of the flaps comprises an actuator, usually electric, pivoting the flaps in synchronism, by means of a control rod.
- the control rod In order to synchronously rotate the flaps, the control rod performs a translational movement. During this translational movement, the control rod can seam and crash or wear prematurely because of this swaying.
- One of the aims of the present invention is therefore to at least partially overcome the disadvantages of the prior art and to provide an improved closure device.
- the present invention thus relates to a shutter device for front air intake of a motor vehicle, comprising:
- a support frame which is installed in at least a first and a second set of pivoting flaps around pivot axes between a closed position and an open position
- control element disposed between two sets of flaps, and configured to control the positioning of the flaps, said control element comprising:
- an actuator having first and second opposite sides, the actuator having a rotating output member on the first side face, and
- a lever connected at one end to the actuator output rotating member on the side of the first side face of the actuator, and secondly to the control member so as to rotate the flaps , the connection between the lever and the control member being on the side of the second side face, opposite to said first side face, of the actuator.
- the control member connected to the flaps is opposite the second lateral face of the actuator.
- the lever comprising first and second parallel flanks and positioned on either side of the actuator, said first and second sidewalls being connected by at least one cross member, at least one of said first and second sides second sidewall being connected to the rotary output member of the actuator so as to be moved by said actuator.
- the lever comprises an orifice on at least first or second sidewalls, a drive insert passing through said orifice and being inserted into a corresponding rotary member at the level of the actuator.
- the first sidewall comprises an orifice intended to be traversed by the drive insert and that the second side includes a guide axis disposed in the same axial alignment as the drive insert.
- the guide axis is disposed on a side of the second side facing the actuator and is inserted into a dedicated housing at an actuator support, said actuator support allowing the attachment of said actuator to the support frame.
- the guide axis is disposed on a side of the second side facing away from the actuator and is inserted into a dedicated housing at the support frame.
- the guide pin comes from material with the lever.
- the guide pin is an insert and is inserted into an orifice of the second sidewall.
- the drive insert has a skirt at its end opposite to that inserted into the output of the actuator, said skirt having a shape complementary to a border of the first sidewall so as to be able to drive in movement the lever.
- the drive insert has a complementary shape with the output of the actuator in which it is inserted and with the orifice of the first or second side so as to be able to drive the lever .
- the drive insert comprises a fastening device by elastic deformation at the first or second sidewall.
- control member is made in one piece comprising two connecting rods connecting the flanks of the lever and the flap assemblies, said connecting rods being connected to one another by at least one cross member. spacing.
- control member comprises two independent connecting rods, a first connecting rod connecting the first side of the lever and a first set of flaps and a second connecting rod connecting the second side of the lever. and a second set of shutters.
- FIG. 1 shows a diagrammatic perspective view of a shutter device in a closed position
- FIG. 2 shows a schematic representation in perspective of a control element
- FIG. 3 shows an exploded perspective representation of a lever of the shutter control element
- FIGS. 4a and 4b show perspective representations of a lever of the control element of the shutters according to different points of view
- FIG. 5 shows an exploded perspective representation of a mounting of a lever and an actuator
- FIG. 6 shows an exploded perspective representation of a mounting of a lever, an actuator and a control member according to a first embodiment
- Figure 7 shows an exploded perspective representation of a mounting of a lever, an actuator and a control member according to a second embodiment.
- first element or second element as well as first parameter and second parameter, or first criterion and second criterion, and so on.
- first element or second element as well as first parameter and second parameter, or first criterion and second criterion, and so on.
- it is a simple indexing to differentiate and name elements or parameters or criteria close but not identical.
- This indexing does not imply a priority of one element, parameter or criterion with respect to another, and it is easy to interchange such denominations without departing from the scope of the present description.
- This indexing does not imply either an order in time for example to appreciate such or such criteria.
- an XYZ trihedron shows the angle of view of each of said figures relative to each other.
- the axes of this trihedron can also correspond to the different orientations of the motor vehicle.
- the X axis can thus correspond to the length of the vehicle, the Y axis to its width and the Z axis to its height.
- FIG. 1 shows a schematic perspective view of a shutter device 1 in the closed position.
- This Figure 1 shows more exactly the outer face of the closure device 1, that is to say the face facing the outside of the motor vehicle when the closure device 1 is assembled on the vehicle.
- the closure device 1 comprises a support frame 5 comprising in particular two longitudinal crosspieces 5a, extending parallel to the Y axis of the trihedron, and at least two lateral uprights 5b, extending parallel to the Z axis of the trihedron and connecting the longitudinal struts 5 a.
- the support frame 5 is made for example of plastic.
- the two longitudinal crosspieces 5a and the at least two lateral uprights 5b are thus molded. In order to improve the rigidity of the support frame 5, the latter can be molded in one piece.
- a plurality of flaps 3 Within the support frame 5 is installed a plurality of flaps 3, the latter form rows of flaps 3 parallel to each other and form at least a first 3a and a second 3b set of flaps 3.
- a control element 13 configured to control the rotation of the flap or flaps 3 around a pivot axis A, between an open position (visible in FIG. 2), where the flaps 3 are positioned so that that an air flow can pass through the closure device 1, in particular inside the support frame 5, and a closed position illustrated in FIG. 1, where the flaps 3 are positioned so that a flow air can not pass through the shutter 1.
- FIG. 1 more specifically shows a closure device 1 comprising three sets 3a, 3b and 3c of shutters 3.
- the control element 13 comprises in particular a control member 7.
- the shutters 3 each comprise a control arm 30, perpendicular to their pivot axis A and carrying a connecting pin B allowing the connection between said control arm 30 and the control device 7.
- the pivot axis A and the connecting axes B are all parallel to the Y axis of the trihedron.
- the control arm 30 is generally made of material with the shutters 3.
- control member 7 can be made in one piece with two connecting rods 70a, 70b. Said rods 70a, 70b are interconnected by at least one spacer beam 71, preferably by a spacer beam 71 at each end of the connecting rods 70a, 70b. Such a control member 7 is rigid and allows good synchronization of the movements of the sets 3a, 3b of flaps 3.
- the control element 13 also comprises an actuator 9.
- the actuator 9 may be electric, such as for example an electric motor.
- the actuator 9 applies to the control member 7 a translational movement by means of a lever 11. This translation is along the Z axis of the trihedron.
- the flaps 3 can pivot each about their pivot axis A defined by their connection with the support frame 5.
- the connecting pins B between the flaps 3 and the control member 7 are eccentric with respect to the pivot axes A so that that a translation movement, parallel to the Z axis of the trihedron, of the control member 7, under the action of the actuator 9, causes the flaps 3 to pivot about their respective pivot axes A and therefore the passage of said flaps 3 from one position to another.
- the lever 11 comprises a first 11 and a second 112 parallel flanks and configured to be positioned on either side of the actuator 9 (see Figures 6 and 7). These first 111 and second 112 flanks are connected by at least one cross member 113. At least one of said first 11 and second 112 sidewalls is connected to a rotary member 90 of the output of the actuator 9 so as to be set in motion by the actuator 9.
- the first 1 1 and second 1 12 sidewalls comprise notches 119 for receiving a finger 72 (visible in Figure 6) disposed on the control member 7. These notches 119 and 72 this finger allow the transmission of the rotational movement of the lever 11 and its transformation into a translational movement of the control member 7. It is however quite possible to imagine a variant in which the positions are reversed, the first 111 and second 112 flanks each having a finger and in which the control member 7 has corresponding notches.
- said lever 11 comprises an orifice 115 on at least one of the first 111 or second 112 sidewalls.
- a drive insert 200 passes through said orifice 115 and is inserted into the corresponding rotary output member 90 at the level of the actuator 9 (visible in FIG. 5) so that said actuator 9 can rotate the insert 200 and that said drive insert 200 transmits this movement to the lever 11 in order to translate the control member 7.
- the drive insert 200 and the rotary output member 90 have complementary shapes, for example square, star or any other form allowing the transmission of the rotational movement of the rotary member 90 output.
- the actuator 9 is then preferably an actuator 9 comprising only one rotary member 90 output. It is however, it is entirely possible to imagine another embodiment in which the actuator 9 comprises two rotary output members 90 and where a first rotary member 90 can be connected to the first side 11 1 by a first drive insert 200 and in which a second rotary member 90 can be connected to the second sidewall 112 by a second drive insert 200.
- the drive insert 200 may comprise a skirt 210 at its end opposite to that inserted in the rotary member 90 of the actuator 9.
- This skirt 210 extends perpendicularly to said insert and has a shape complementary to a border 11a. of the first sidewall 111, so as to be able to drive the lever 11 in movement.
- said skirt 210 may in particular have a relatively triangular shape around the drive insert 200 and be inserted into a complementary triangular shape defined by the border 111a of the first sidewall 111.
- the drive insert 200 may have a complementary shape with the orifice 115 of the first 111 or second sidewall 112 so as to be able to drive the lever 1 1 in movement.
- the drive insert 200 and the orifice 115 may be square, starred or have any other form allowing the transmission of movement.
- the drive insert 200 may also include an elastic deformation fastener 220 at the first 11 1 or second 112 flank to hold the drive insert 200 in both the orifice 115 and the rotatable member 90 of the actuator 9.
- the elastic deformation fixing device 220 may in particular comprise an elastic hook mount on the drive insert 200 (visible on the 3) and cooperating with the inner rim of the orifice 115 or with a dedicated lug disposed within said orifice 115.
- the first side 11 of the lever 11 comprises an orifice 115 intended to be traversed by the driving insert 200.
- the second sidewall 112 may comprise a guide pin 300 disposed in the same axial alignment as the drive insert 200.
- the guide axis 300 and the drive insert 200 thus define an axis of rotation around which the lever 11 can rotate.
- the drive insert 200 and the guide pin 300 respectively serve as fulcrum and rotation for the first 11 1 and second 112 flanks.
- the guide pin 300 may be disposed on one side of the second sidewall 112 facing towards the actuator 9 as illustrated in FIGS. 3 to 5.
- the guide axis 300 is then inserted into a housing 80 dedicated to the level of an actuator support 8, as shown in Figure 5.
- the actuator support 8 allows the attachment of the actuator 9 to the support frame 5.
- the first sidewall 111 and the second side 112 of the lever 11 are then arranged from and other of the assembly formed by the actuator 9 and its support 8.
- the guide axis 300 may be disposed on a side of the second sidewall 112 facing away from the actuator 9. The guide axis 300 is then inserted into a dedicated housing at the support frame 5.
- the guide pin 300 can be made of material with the lever 11 as illustrated in Figures 3, 4a and 4b. This embodiment simplifies the manufacture of the lever 11 and avoids the use of an additional part during assembly. Conversely, the guide pin 300 may be an insert and which is inserted into the orifice 115 of the second sidewall 112. This embodiment makes it possible, for example, to facilitate the mounting of the lever 11 on the actuator 9.
- the control member 7 may comprise two rods 70a, 70b independent. A first connecting rod 70a makes the connection between the first flank 111 of the lever 11 and a first set of flaps 3 and a second connecting rod 70b makes the connection between the second flank 112 of the lever 11 and a second set of flaps 3.
- Such a member Command 7 is lightweight and space-saving.
- the shutter device 1 according to the invention from its lever 11 reduces the risk of sway of the control member 7 and thus reduces the risk of blockage.
