    [0001] The present invention relates to a cam device for controlling at least one member, a system for operating at least one moving part comprising said cam device and a device. heating, ventilation and / or air conditioning, particularly for motor vehicles, including such a maneuvering system. A motor vehicle is commonly equipped with an installation for heat treatment of an air flow, also called a heating, ventilation and / or air conditioning system, to modify the aerothermal parameters of a flow of air intended to be distributed to inside a passenger compartment of the vehicle. For this purpose, the heating, ventilation and / or air conditioning system comprises a heating, ventilation and / or air conditioning device for channeling the air flow before it is distributed inside the passenger compartment. The heating, ventilation and / or air conditioning unit is preferably housed under a dashboard of the vehicle disposed in the front part of the passenger compartment of the vehicle. The heating, ventilation and / or air conditioning unit generally includes an air inlet box and a heat treatment box.
    [0002] The heat treatment unit comprises various airflow heat treatment components, among which, on the one hand, heat exchangers, such as an evaporator and / or a radiator, can be distinguished for the heat treatment of the flow of heat. air, in particular by making it possible to cool and / or dehumidify it and / or to heat it, and, on the other hand, aeraulic management means, such as a blower, making it possible to channel the flow of air and distribute it in various areas of the cabin. The distribution means installed in the heat treatment box distribute the flow of air leaving a mixing chamber, located downstream of the exchangers, between different air ducts opening into various areas of the passenger compartment, in particular the area of the windshield for de-icing, the central zone of the dashboard for ventilation of the passenger compartment and the zone 3032020 2 of the feet of the front passengers of the vehicle, each air duct being able to be closed or opened by a shutter actuated by a lever. It is well known that these heating, ventilation and / or air-conditioning apparatus of motor vehicles, so-called HVAC (Heating, Ventilation and Air-Conditioning), commonly use cams to move one or more levers in a synchronized manner and / or to follow a particular law of motion to open and close an air duct via valves or flaps of the dispensing means.
    [0003] These cams are coupled to an axis of rotation adapted to perform a rotary reciprocating movement corresponding to the desired reciprocating movement of opening and closing of said flaps or flaps. The axis of rotation of the cam can be actuated by means of an electric motor, or manually by means of a cable.
    [0004] Said cams comprise a perimetric cam path defined between an outer wall and an inner wall, the cam path moving more or less away from the axis of rotation between its two distal ends. It is thus possible to modify the positioning of cam followers that can slide in the cam path.
    [0005] Such a cam device is in particular described in the document FR 2 335 753. The latter has an operating device for a transmission member such as pull cable or wheelhouse, in motor vehicles, which is articulated on a lever supported at rotation and having a journal engaged in a cam path in a rotating cam.
    [0006] Said cam has a disc shape and has a spiral-shaped cam path on each of these faces. The cam paths are arranged head to tail in the thickness of the cam. Although interesting because for guiding multiple cam followers through their different faces, this type of cam device 30 has a large footprint in the direction of the axis of rotation of the cam.
    [0007] The invention aims to improve the situation by proposing a cam device for controlling at least one member, said device comprising a cam comprising at least a first cam path on a first face and a second cam path on an opposite face, said first cam path having a depth, measured from an aperture, at said first face, said first cam path, and said second cam path having a depth, measured from an aperture, at said opposite face, of said second cam path, a height of the cam between the aperture of the first and second cam paths being less than the sum of the depths of the cam paths. The cam device according to the invention thus provides interpenetration of the cam paths of the opposite cam faces, thereby significantly reducing the thickness of the cam and hence its bulk. According to various embodiments of the invention, taken together or separately: each cam path has a rectangular or square cross-section, at least one of the cam paths of the first face of the cam is intersecting with the cam. at least one of the cam paths of the opposite face of said cam, said paths being said to be cut, the cam track (s) cut off from the first face of the cam open on the cam track (s) cut from the face opposite of said cam to a height less than the depth of said one or more cam paths cut from the opposite face of said cam, the cam comprises a central axis of rotation, the cam has a disc shape, each path of cam has a different depth.
    [0008] The invention also relates to a system for operating at least one moving part, said system comprising a cam device as mentioned above.
    [0009] According to various embodiments, said system may have the following additional characteristics, taken together or separately: said system comprises at least one lever driven by the movement of the cam and one end of which has a follower roller adapted to sliding in one of said cam paths, said lever being configured to actuate said moving part, - said follower roller has a height less than the depth of the corresponding cam path, - the follower roller locally bears on an inner wall of the cam path to a depth less than or equal to 50%, or even 1/5 of the depth of said cam path. The invention further relates to a heating, ventilation and / or air conditioning system comprising an operating system as described above. Advantageously, said moving part is a component of said installation, in particular a distribution flap. However, this application of the invention is not limiting and it goes without saying that the cam device according to the invention will find many applications, whether the cam is rotary or translative, without departing from the scope of the invention. invention. The invention will be better understood in the light of the following description which is given for information only and which is not intended to limit it, accompanied by the attached drawings among which: FIG. a perspective view of the cam device according to the invention for the operation of distribution flaps of a heating, ventilation and / or air-conditioning apparatus of a motor vehicle, - Figure 2 is a perspective view from below of the device 5 is a perspective view from above of the cam device according to the invention, provided with the control levers of the flaps; FIG. perspective view of a radial section of the cam device according to the invention, provided with the control levers of the flaps, - Figure 5 is another perspective view from above of the cam device according to the invention, without the levers shutter control, - the figur 6 is another perspective view from below of the cam device according to the invention, without the flap control levers; FIG. 7 is another perspective view of a radial section of the cam device according to the invention; invention, without the control levers flaps. With reference to FIG. 1, the cam device according to the invention is integrated, in this particular example, into a control device for a motor vehicle heating, ventilation and / or air-conditioning device 1, called HVAC, intended for be located in the front part of the passenger compartment of a vehicle, not shown in the figure, and housed under a dashboard of the vehicle, also not shown. Said heating, ventilating and / or air conditioning apparatus 1 comprises a heat treatment box 2. Only an upper face of said housing 2 has been illustrated, the remainder of the housing having only been shown, in dashed lines, by its outline. Said housing 2 comprises various components of heat treatment of the air flow such as an evaporator and / or radiator, not visible, intended for the heat treatment of the air flow, in particular by allowing it to be cooled and / or dehumidify it and / or reheat it, and aeration means 3 for channeling the flow of air and distribute it in various zones of the passenger compartment, such as the windshield area, the foot area and the central area. For this purpose, the aeraulic management means 3 comprise several mouths, connected to ducts respectively supplying the windshield area, mouth 4a, the foot area, mouth not shown, and the central area, mouth 4c. Said mouths are provided with flaps, not shown in FIG. 1, controlled by a cam device 5. With reference to FIGS. 1 to 4, the cam device 5 consists of a cam 6 having here a general disc shape and provided on one of its faces, in this case its outer face, two cam paths 7 and 8 and on its opposite face, that is to say its face facing the heat treatment box 2, d a cam path 9. Said cam is formed, for example, by molding, in particular a plastic material.
    [0010] Each cam path 7, 8 and 9 receives a follower roller 10, 11 and respectively 12, integral with one end of a lever 13, 14 and 15 respectively, the opposite end of each lever being integral with an actuating member 16, 17 and 18 respectively of a flap of the aeraulic management means 3, this by means of possible return members.
    [0011] It goes without saying that the follower rollers 10, 11 and respectively 12 may be substituted by any other equivalent means well known to those skilled in the art without departing from the scope of the invention. Said cam 6 comprises in its central part an axis of rotation 19 in order to ensure the rotation of said cam relative to the heat treatment box 2. The rotation of the cam about its axis of rotation 19 determines its angular position, and as a result, the position of the follower rollers 10, 11, 12, along their respective cam path 7, 8 and 9. The cam paths 7, 8 and 9 have a path allowing the follower rollers 10, 11, 12, to move away more or less from the axis of rotation 19. They act in this way 30 on the positioning of the flaps to which they are connected.
    [0012] Referring to Figures 4 and 7, each cam path 7, 8 and 9 has a substantially rectangular or square cross-section and a depth h1 and h2 just below the height h of the disc forming the cam 6. Thus, the height h of the cam 6 is less than the sum of the 5 depths (hl + h2) of the cam paths 7, 8 and 9 of the two opposite faces of said cam 6, the height h being measured between the opening of the cam paths 7, 8 and 9 on the face at which they open. In other words, the cam paths 7, 8 and 9 are nested in the thickness of the cam rather than being one in a first axial half of the thickness of the cam and the other in the other. axial half of the thickness of the cam. Here, the faces of the cam have a lip 20 along the cam paths 7, 8 and 9 and the opening of the cam paths is considered to be located at an upper edge 22 of this lip 20 so that the Cam depth is measured between said upper edge 22 and a flat bottom 24 of the cam path. As for the thickness of the cam, it is measured between the upper edge 22 of the lips of the cam paths on each of the opposite faces of the cam. In a variant, the lip may not be present and the depth of the cam paths will then be measured from the general extension surface 20 of the corresponding faces of the cam. Likewise, the thickness of the cam will be measured between the general extension surfaces of the opposite faces of the cam. In a variant, the bottom of the cam may not be flat and the depth of the cam will then be measured, for example, with respect to the deepest point. It should be noted that the depths h 1 and h 2 of the cam paths 7, 8 and 9 may be equal or different. The follower rollers 10, 11 and 12 bear on one or other of the side walls of the cam paths, said internal wall of the cam path 7, 8 and 9 to a depth less than the depth h1 or h2 of said path 7, 8 and 9. Preferably, the bearing depth of the follower rollers 10, 11 and 12 is between 1 and 5 mm. It extends from the opening of the cam paths 7, 8 and 9 towards the bottom thereof.
    [0013] With reference to FIGS. 5 to 7, the cam paths 7, 8 of the outer face of the cam 6 open on the cam path 9 of the opposite face of said cam 6 to a height less than the depth h1, h2 cam paths. In other words, the cam track (s) of one of the faces may cross the cam track (s) of the opposite face. Said cam paths 7, 8 here in this way present, locally, the passage windows of the follower follower of the cam path 9 of the opposite face of the cam, and vice versa, said windows being located at their internal walls. To avoid blocking, the angular position of the 10 follower rollers will be provided so that two follower rollers are not simultaneously at the same time at a cross. Preferably, at the level of said crossings, the one or more cam paths open onto each other over a height less than their depth so that there remains a fraction of depth Z of support of the follower rollers 15 at their level. internal face. Said fraction of depth Z extends from the opening of the cam paths 7, 8 and 9, for example to a height less than 50%, or even 1/5 of the depth of said cam paths 7, 8 and 9. Said cam may further comprise one or more articulation wells of different axes, in particular axes of articulation of the actuating members. It is obvious that the cam device according to the invention may comprise a cam guided in translation and not in rotation without departing from the scope of the invention.
    [0014] Finally, it is obvious that the cam device according to the invention can be adapted to all types of control of an organ as well as any type of organ. Similarly, the exemplary embodiments given above are only particular illustrations that are in no way limiting as to the fields of application of the invention. 30
