Definitions
- the present invention relates to shutter devices and more specifically to a device for closing the air inlet of the front face 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 flaps are moved by means of a control device comprising in particular a control member such as a connecting rod and an actuator.
- the actuator is generally a motor that transmits a rotational movement to a lever. During its rotation, the lever drives the control member in a movement translation that allows the closing or opening of the shutters.
- the actuator may comprise two levers arranged on the same axis of rotation and on both sides. other of the actuator.
- the lever may comprise a lever holding device such as for example a direct attachment of the lever to the actuator or via a tongue.
- An object of the present invention is therefore to at least partially overcome the disadvantages of the prior art and to provide an actuator-lever assembly and an improved closure device.
- the present invention thus relates to an actuator-lever assembly for a shutter device for front air intake of a motor vehicle, said assembly comprising:
- an actuator having two output rotary members comprising a hollow and each disposed on one side of said actuator and on the same pivot axis, and
- the actuator-lever assembly makes it possible to avoid the flap of the flaps while guaranteeing a minimum assembly time.
- the rotary output members are disposed on opposite faces of said actuator.
- each lever comprises at the end of its stud a flexible tongue eccentric with respect to the pivot axis and extending in the communication orifice, said tongue comprising, on its face in view of the pivot axis, a notch engaging the notch of the tab of the opposite lever.
- the tongue comes from material with the lever.
- the notch comprises a first slope directed away from the pad and a second slope directed towards said pad, the first slope having a slope value lower than the second slope.
- the levers comprise an appendage extending in the communication port and covering the face of said tab opposite its face having the notch.
- the levers (11) are identical.
- the present invention also relates to a shutter device for front air intake of a motor vehicle, comprising an actuator-lever assembly as described above.
- 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 a diagrammatic representation in perspective and in section of an actuator-lever assembly
- FIG. 4 shows a schematic representation in perspective of a lever
- FIG. 5 shows a schematic representation in perspective of an actuator-lever assembly during a first step of the assembly process
- FIG. 6 shows a schematic representation in perspective of an actuator-lever assembly during a second step of the assembly process
- FIG. 7 shows a schematic side view of a tongue of the lever of FIG. 4.
- the identical elements in the different figures bear the same references.
- 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.
- Figure 1 shows a schematic perspective view of a shutter device 1 in the closed position. This figure 1 shows more exactly the face external shutter device 1, that is to say the face facing the outside of the motor vehicle when the shutter 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 shutter device 1 comprising three sets 3a, 3b and 3c of shutters 3.
- the control element 13 comprises in particular a control member 7.
- the flaps 3 each comprise a control arm 30, perpendicular to their pivot axis A and carrying a connection axis B enabling 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.
- the control member 7 may 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 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 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 two levers 11. This translation is along the Z axis of the trihedron.
- FIG. 3 shows an actuator 9-lever assembly 11, according to the invention, in section at the connection between the actuator 9 and the levers 11.
- the actuator 9 comprises two rotary output members 90 each comprising a hollow 91 These rotary output members 90 are each arranged on a distinct face of said actuator 9 and have the same pivot axis C.
- a lever 11 is inserted into each rotary output member 90.
- the recesses 91 of the rotary output members 90 are connected to one another through a communication port 92 within the actuator 9 itself.
- the levers 11 each comprise a stud 110 inserted in a recess 91 of a rotary output member 90.
- the recess 91 and the stud 110 are of complementary shape so that the lever 11 is rotated by the rotation of the organ rotary output 90.
- the pad 110 may for example be of square shape, or comprise one or more keys 120 (visible in Figure 4).
- the lever 11 comprises in particular a lever arm 115. At one end of the lever arm 115, the stud 11 protrudes perpendicularly to said lever arm 115. At the other end of the lever arm 115 , the lever 11 comprises a connection device 116 to the control member 7, here an oblong slot in which a connecting finger of the control member 7 is intended to be inserted.
- the levers 11 are fixed to each other through said communication port 91 by an elastically fitting fastener as shown in FIG. 3.
- the communication orifice 91 is dimensioned so that the elastically fitting fastener can pivot. in it at the same time as the levers 11 pivot.
- This fastening with elastic casing allows easy attachment of the levers 11 within the rotary output members 90 without adding additional fixing steps during the manufacturing process. It is thus enough to put in front of the levers 11 and the rotary organs of output 90, as shown in Figure 5. More precisely it is sufficient to align the pads 110 on the pivot axis C and insert the pads 110 in the recesses 91, as shown in Figure 6.
- the fitting casing resilient between the levers 11 may include a flexible tongue 112 extending from the pad 110.
- This tongue 112 is eccentric with respect to the pivot axis C and extends into the communication port 92.
- the tongue 112 comprises , on its face facing the pivot axis C, a notch 113 engaging with the notch 113 of the tongue 112 of the lever 11 opposite.
- the tongue 112 may in particular come from material with the lever 11.
- This embodiment allows in particular to have two levers 11 identical and therefore can be from the same manufacturing process for example by means of a single mold in which is injected with plastic material.
- the fact of having identical levers 11 that can come from a single mold allows production savings but also avoids the need to distinguish levers 11 different in order to properly place. The manufacturing and assembly process is thus simplifying.
- the levers 11 may also comprise, at the end of its stud 110, an appendix 114 extending in the communication orifice 92 and covering the face of said tongue 112 opposite its face having the notch 113.
- This appendix 114 allows to protect the tongue 112 and also serves as a key to position and correctly align the levers 11 relative to each other.
- this appendix 114 may be of hemispherical shape and come integrally with the lever 11 in the same way as the tongue 112.
- the notch 113 may more particularly comprise a first slope 113a directed opposite the stud 110 and a second slope 113b. directed towards said stud 1 10.
- the first slope 113a may in particular have a lower slope value than the second slope 113b. This difference in slope value makes it possible to put the notches 113 into easy contact, while it is necessary to apply a greater force to undo the fixing between the levers 11.
- the actuator assembly 9 - lever 11 allows easy attachment of the levers 11 with each other and without the need to perform complex or additional manipulations during the assembly process of the shutter device 1.
