Abstract

The headlight dip switch command has a flexible mechanical piece (23) which is pushed forward into a curved section flexing around a first axis. After passing a first stable position a second component moves along a second axis, and a curved mechanical piece (32) holds the flexible mechanical piece in a second stable position. When the flexible section is removed from the curved mechanical piece the flexible section returns to its first position.

Description

The present invention relates to the field of switches

  electric motors.

  The present invention applies in particular, but not exclusively to the realization of a control switch for electric lighting of motor vehicles, designed to provide a switching

  between high beam and low beam.

  Many electrical switches of this type have already been

proposed.

  For example, the document FR 2 737 039 describes an electrical switch, in particular for a motor vehicle, comprising switching means and means for indexing or temporary locking of the switching means. These locking means comprise a core cam and a finger adapted to come into engagement with the core cam during a relative movement of the finger relative to the core cam. The finger is attached to the end of a rod. It undergoes, during a relative movement of the finger relative to the heart cam generally parallel to the longitudinal axis of the rod, a movement perpendicular to this axis, in which it is guided so that it

  can go around the heart cam, totally and unequivocally.

  An object of the invention is to improve the known indexing means. An auxiliary object of the present invention is to reduce the stroke of the

  finger along the longitudinal axis of the stem.

  In order to achieve this object, an electrical control switch for a motor vehicle is provided according to the invention, comprising indexing means comprising a finger and a notch, the finger being able to undergo a relative elastic movement with respect to the notch, in a plane, this displacement comprising a first component along a first axis passing through a first stable position and a second component along a second axis perpendicular to the first axis, the notch being able to hold the finger in a second position stable, the switch being characterized by the fact that the finger is adapted to return elastically towards the first axis,

when it comes out of the notch.

  Thus according to the invention, the finger can out of the notch by elasticity, following a displacement having a component along the second axis. It is then unnecessary to use an additional stroke of the finger along the first axis to constrain it by means of guiding, to perform

  a displacement along the second axis, to exit the notch.

  Advantageously, the switch comprises a first part of which a first arming face and a second clearance face are perpendicular to said plane and intersect the first axis, the notch being situated between the first arming face and the second face. clearance, at the end of the first arming face, furthest from the initial contact area between the finger and the first face, from the first stable position. This so that the first arming face constrains the finger to bring it to the entrance of the notch, during a movement from the first to the second stable position, and the second release face, forces the finger out of the notch to iron under the first face, during a movement of the second to

the first stable position.

  Advantageously, the first and second faces generally form a dihedron, the notch being between the first and second faces. This is so that the angle between the second face and the first axis is lower than that between the first face and the same axis. As a result, friction on the second side will be

  minimized compared to those on the first side.

  Advantageously also, when the finger is moved from the first stable position to the second stable position, it is successively in contact with the first arming face and a third constituent face of a second part. This third face, being perpendicular to said plane of translation and oriented in one direction

  away from the first axis, is able to direct the finger in the notch.

  However, for the finger to come into the notch at the second stable position, on the one hand, the third face has a closest apical point - T - of the bottom of the notch, located on the same side as the notch relative to the first axis. On the other hand, the dimension of the finger in the direction parallel to the first axis is sufficiently large compared to that corresponding to the difference between the projections, on the first axis, of the apical point and the last point of the first face with which the finger is in contact before being recalled to the notch, when the finger is moved in a direction parallel to the first axis, so that the finger is retained above the notch by the second piece. And finally, the projections on the second axis, the apical point and the position of the finger in the second stable position, are offset relative to each other, the projection of the apical point being radially more external compared to the first axis than that of the

  finger position in the second stable position.

  In another aspect, the invention is a control box

  electrical device comprising a switch according to that defined above.

  Other aspects, objects and advantages of the invention will become apparent

  reading the detailed description that follows.

  The invention will also be better understood from the references to the drawings in which: - Figure 1 is a perspective representation of an electrical switchbox including a lighting control switch according to the present invention; FIG. 2 schematically represents in side elevation the main elements of a lighting control switch such as that represented in FIG. 1, the latter being in a first position

stable;

  - Figure 3 is a representation similar to that of Figure 2, the switch being in a first intermediate position; - Figure 4 is a representation similar to that of Figures 2 and 3, the switch being in another intermediate position; - Figure 5 is a representation similar to that of Figures 2, 3 and 4, the switch being in a second stable position; FIG. 6 is a representation similar to that of FIGS. 2, 3, 4 and 5, the switch being in yet another intermediate position and FIG. 7 is a representation similar to that of FIGS. 2, 3, 4, 5 and 6, the switch being in yet another intermediate position. A first embodiment, particular but not limiting, of the present invention is described below in relation to FIGS. 1 to 7. FIG. 1 represents an electric lighting control box, in particular for switching between lights of road and low beam, comprising a support 100, a lever 200, a return spring 300 and a slider 1 movable on a path between two stable positions A, C, generally located at each end thereof

race.

  The slider 1 moves under the effect of the lever 200 or the return spring 300, in a translation movement relative to the housing 100. The return spring 300 is placed between the support 100 and the slider 1. The slider 1 is solicited thus in his race by the spring

  300 reminder that opposes a force that exerted by the lever 200.

  The slider 1 has a drawer shape with: - two side walls, generally parallel to each other, - a third wall 15 on which the lever 200 acts, perpendicular to the side walls, joining one end of each of the latter, and perpendicular to the direction of translation of the slider 1, - and a bottom wall 17 perpendicular to the previous three

  walls and defining the translational plane P of the slider 1.

  The two side walls of the slider 1 extend from the

  third wall 15, towards the support 100.

  The two side walls of the slider 1 constitute a first and a second lugs 14, 16 extending in the direction of translation of the slider 1. Each of the lugs 14, 16 has two parts succeeding one another in this direction of translation. One of these parts constitutes

  a support zone 6 or 8 and the other defines a recess 10 or 12.

  The difference, considered in a direction perpendicular to the direction of translation of the slider 1, between the bearing zones 6 and 8 respectively of the first and second legs 14 and 16 is greater than that between the

  parts corresponding to the two recesses 10, 12.

  A bearing zone 6 at one of its ends, adjoins the third wall 15. This bearing zone is on the first leg 14. The other

  support zone 8 is located towards the free end of the second tab 16.

  This other support zone 8 which is on the second leg 16, is thus further away from the third wall 15 than is the previous zone

of support 6.

  The projections of the support zones 6 or 8, on the axis of translation of the slider 1, are offset relative to each other on this axis and do not have overlap. The projections on the axis of translation of the slider 1, parts corresponding to the recesses 10, 12, are offset on this axis, one with respect to the other, but have a range

recovery.

  Two blades 2 and 4 extend generally parallel to the direction of translation of the slider 1. These two blades are placed generally parallel and adjacent to the outer face of the two side walls of the slider 1, constituting the first and

second legs 14, 16.

  Each blade 2, 4 consists of a folded conductive strip

  in the form of a U. Advantageously, these blades 2, 4 are brass.

  Each blade 2, 4 is elastic. One of the branches of the U is secured to the support 100. The other branch of the U is free and can come to bear on a high beam contact 40 or crossing 50, rigidly connected to the support 100. The branches of U solidarity of the support 100 are further apart than are the free branches of the U. The free branch of each blade 2, 4 is adjacent to the first or the second tab 14 or 16. The elasticity of the blades 2, 4 makes it possible to make a good quality electrical contact between the blades 2, 4 and the main beam contacts 40 or crossing 50. Each blade 2, 4 is preferably provided at the high beam contacts. 40 or crossing 50, a contact bump

adequate and classic.

  The free branch of each blade 2, 4 has a protrusion 3, 5 extending towards the first or the second lug 14, 16 adjacent. The projection of a protuberance 3 or 5 on the axis of translation of the slider 1 is at the same level, on this axis, as that of the other protuberance 5 or 3. Each protrusion 3 or 5 is able to come into contact of a bearing zone 6 or 8, but alternately during the translation of the slider 1 and never simultaneously, this thanks to the overlapping range of projections of the recesses 10, 12, on the axis of translation of the slider 1. Thus, when the slider 1 is in the first stable position A, only one protuberance 5 or 3 is in contact with a bearing zone 8 or 6. This protuberance 5 or 3 moves the adjacent blade 4 or 2 towards the fixed branch. corresponding. The free branch of the corresponding blade 4 or 2 is then no longer supported by the main beam contact 40 or the low beam contact 50. However, the other protuberance 3 or 5 is in a recess 10 or 12. This protrusion 3 or 5 then does not touch the lug 14 or 16 adjacent and the free branch of the blade 2 or 4 correspondence can come to bear on the contact of low beam 50 or high beam 40. In the second stable position C, after translation of the slider 1, the respective situations of the protuberances 5, 3 are reversed, with respect to the bearing zones 6, 8 and recesses 10, 12. In an intermediate position, the two protuberances 3, 5 are each in a recess 10, 12. The two free branches of the blades 2, 4 are then supported on the main beam contacts 40 and crossing 50. The high beam and low beam circuits are thus not never open simultaneously during translation of the slide 1. Thus we avoid the phenomenon usually called "black hole" by specialists, which corresponds to a total and temporary extinction of the vehicle lighting means, although

  heard very annoying for a driver.

  Indexing means of the slider 1 allow the latter to be held in the two stable positions A, C. These indexing means are advantageously a rod 20 and a core cam 24. They are partly

  represented in box in FIG.

  The rod 20 extends in the middle of the tabs 14, 16 of the slider 1, generally parallel to the translation direction of the latter along a first axis 0-0. It has a free end 21 and a fixed end 22. The free end 21 corresponds to the end of this rod 20 closest to the third wall 15 of the slider 1. This free end 21 is provided with a perpendicular finger 23 to the translation plane P of the slide

  1, which finger 23 is directed towards the bottom wall 17 of the slider 1.

  The fixed end 22 corresponds to the other end of the rod 20. This fixed end 22 is integral with the support 100. The rod 20 has an elasticity in the translational plane P of the slide 1, perpendicular to the direction of translation of the rod. last, ie according to a second

  axis 0'-0 'perpendicular to the first axis 0-0.

  The core cam 24 is formed on the inner face of the bottom wall 17 of the slider 1. It comprises two parts 25, 29 each having a face parallel to the translation plane P of the slider 1, and to the wall of

  bottom 17, and generally triangular.

  A first piece 25, generally heart-shaped has its tip directed generally towards the fixed end 22 of the rod 20. It further comprises two faces 26, 27, located between the face parallel to the translational plane P of the slider 1 and the bottom wall 17, and perpendicular to the translational plane P of the slider 1. The first face 26 is generally facing the fixed end 22 of the blade 20 and the inner face of the first lug 14. This first face 26 intersects the first axis 0-0 and is oblique with respect to the latter. The second face 27 is generally facing the third wall 15 of the slider 1 and the second tab 16, that is to say that this second face 27 is generally facing the direction opposite to that directed towards the fixed end 22. This second

  face 27 intersects the first axis 0-0 and is oblique to it.

Tii ---

  The first 26 and second 27 faces thus form globally a dihedron whose planes are perpendicular to the plane P of translation of the

  slide. A notch 32 is located between the two planes of this dihedron.

  The notch 32 has its concavity directed away from the fixed end 22 of the rod 20. The notch 32 is able to hold the finger 23 in the second stable position C. The longitudinal axis of the rod 20 constraint, that is to say the axis 0-0, does not pass through the notch 32. The finger 23 can not be

  in the notch 32 only when the rod is elastically constrained.

  Thus, from its apical point 260, the closest to the fixed end 22 of the rod 20, the first part 25 is defined by: a first face 26 serving as an armament for the rod 20, generally convex towards the outside, which intersects the axis 0-0, at the right of the rest position of the finger 23 and which converges towards the third wall 15 (it moves away from the fixed end 22 of the rod 20) towards the first lug 14 (ie away from the axis 0-0), - a notch 32 serving as a lock to the rod 20, formed on a wall of the first part 25 generally transverse to the axis 0-0 , that is to say which approaches the axis 0-0 from its junction zone on the first face 26 (this wall of the first part 25 generally transverse to the axis 0-0 and bearing the notch 32, not intercepts this axis 0-0), the concavity of the notch 32 being directed opposite the fixed end 22 of the rod 20, and - a second face 27, servo and clearance to the rod 20, which serves as a connection between the edge of the notch 32 closest to the axis 0-0 and the apical point 260, which second face 27, generally convex outwards, from its junction on the notch 32, intersects the axis 0-0 and diverges with respect to the third wall 15 (it is close to the fixed end 22 of the rod 20) towards the second leg 16 (c ' is at

  say away from the 0-0 axis) to the apical point 260.

  The second piece 29 adjoins the third wall 15. It is therefore situated opposite the first piece 25, with respect to the fixed end 22 of the rod 20, opposite the notch 32. This second piece 29 comprises third 30 and fourth 31 faces, located between the face parallel to the translation plane P of the slider 1 and the bottom wall 17, and perpendicular to the translation plane of the slider 1. The third face has a common edge with the inner face of the third wall 15 and is generally rotated as the first face 26, but does not cut the first axis 0-0. The fourth face 31 is generally curved and turned towards the second lug 16. This fourth face 31 does not cut the first axis 0-0 either. The edge common to the third 30 and fourth 31 faces is opposite the notch 32 and constitutes an apical point 28 of

the second room 29.

  The translation steps for moving from the first stable position A to the second stable position C, and vice versa, are

illustrated in Figures 2 to 7.

  The actuation of the lever 200 makes it possible to move the slider 1 from the first stable position A, shown in FIG. 2, to the second stable position C, represented in FIG. 5, as well as from this second stable position C, to the first stable position A, passing through

  intermediate positions B unstable.

  To aid understanding, indexes A, B and C are represented on the second tab 16, in FIG. 1, in correspondence of the projection of the finger 23 on this second tab 16, when the slider 1 is in the

  position denominated by one of these three letters.

  As shown in Figure 2, the core cam 24 is disposed on the bottom wall 17 of the slider 1, so as not to cooperate with the rod 20, when the slider 1 is in the first stable position A. In the first position Stable A, the third wall 15 is in its position farthest from the finger 23. At rest, in the first stable position A, the finger 23 is under the first face 26, so that when the slider 1 is moved under the effect of the lever 200, towards the support 100 parallel to the first axis 0-0, the free end 21 of the rod 20 approaches the first part 25 of the core cam 24, until the

  finger 23 comes into contact with the first face 26 (FIG. 3).

  In this stable position A, the blade 2 rests against the contact of the low beam headlights 50, since the protuberance 3 of this blade 2 is at a recess 10. On the other hand, the protuberance 5 of the other blade 4 rests on a support zone 8 and because of this, the circuit of the lights of

  road is open at the level of the main beam contact 40.

  The orientation and position of the first face 26 described above allows the finger 23 to slide on it, when the slider 1 is translated under the action of the lever 200, the first A to the second C stable position. During the sliding of the finger 23 on the first face 26, the slider 1 passes through a first intermediate position B, in which none of the two protuberances 3, 5 of the slats 2, 4 rest on the bearing zones 6, 8. The blades 2, 4 then, advantageously via contact beads, both respectively the contact of the main beam 40 and the contact of the dipped beam headlamps 50. The high beam and low beam circuits are therefore closed at the level

  contacts of main beam 40 and low beam headlamps 50.

  Those skilled in the art will understand that during the sliding of the finger 23 on the first face 26, away from the first stable position A, the rod 20 is elastically constrained and tends to urge the finger 23 into position.

  approaching the 0-0 axis (see Figure 3).

  When the lever 200 is released before the finger 23 escapes the first face 26 and the sliding of the finger 23 on the first face 26 does not end with a jump of the finger 23 on the third face 30, the spring 300 acts on the slider 1 to return it to its first stable position A. So by a bias of the lever 200 does not correspond to the total stroke of the finger 23 on the first face 26, it was possible to temporarily close the high beam circuit . This possibility corresponds to the "call

of lighthouses ".

  If on the other hand, the lever 200 is actuated so that it continues its action on the slider 1 to bring it to the second stable position C, the finger 23 escapes the first face 26 and is brought into contact with the third face 30, on the second piece 29 (Figure 4). Indeed, the distance between the first piece 25 and the second piece 29 is such that the finger 23 comes into contact with the third face 30 after having slid along the first face 26, under the action of the lever 200, without

  pass directly on the first axis 0-0, or stay in the notch 32.

  For this, the "height" of the finger 23, considered in a projection parallel to the 0-0 axis is greater than the free interval also provided in a projection parallel to the 0-0 axis, between the apical point 28 of the second piece 29 and the point of the functional area between the first face 26 and the notch 32 closest to the third wall 15 or the second

Exhibit 29.

  The correct accomplishment of this function can possibly be facilitated by means of a finger 23 having two branches 33, 34 extending perpendicularly to the translation plane P of the slide 1, in the vicinity of the free end 21 of the rod 20. first 33 of these branches 33, 34 is located at the end of this free end 21, while the second leg 34 is located slightly below the first branch 33, towards the fixed end 22 of the rod 20. The distance between the parts furthest apart from each other of the two branches 33, 34 (considered in a direction parallel to the axis 0-0) is greater than that situated between the projections, on the first axis 0-0, of the apical point 28 and of

  edge of the notch 32 adjacent to the first face 26.

  Thus, the second branch 34 is still in contact with the first face 26, when the first branch 33 reaches the height corresponding to

  the projection on the first axis 0-0 of the apical point 28.

  According to one variant, the two branches 33, 34 may be replaced by a single tongue extending in the longitudinal direction of the rod 20, between the positions that these branches occupy

  33, 34 if the rod 20 was provided.

  If this operation of the lever is continued, the free end 21 of the

  rod 20 abuts on the third wall 15 of the slider 1.

  As shown in FIG. 5, when the slide 1 initiates a recoil with respect to the support 100, under the action of the spring 300 intervening when the lever 200 is released, the finger 23 is housed in the notch 32. For this purpose, on the one hand, the apical point 28 is closer to the axis 0-0 than the side of the notch 32, directed towards this axis 0-0. On the other hand, the distance separating, in a projection on the 0-0 axis, the apical point 28 and the bottom of the notch 32, at the right of this apical point 28, is greater than the previously defined height of the finger 23. Furthermore, the edges of the notch 32 are offset relative to each other, in projection on the first axis 0-0. The projection of the edge adjoining the first face 26 is closer on the first axis 0-0 than that of the fixed end 22 of the rod 20, the projection of the edge adjacent the second face 27. So, the second branch 34 arrives at a height located in projection on the first axis 0-0, in the segment between the projections of the intersections of the edges of the notch 32, before the

  first branch 33 has lost contact with the third face 30.

  The distance between the parts furthest apart from each other of the two branches 33, 34 is greater than that situated between the projections, on the first axis 0-0, of the apical point 28 and the edge of the notch 32 nearest the first axis 0-0. But this distance is smaller than that between the projections, on the first axis 0-0, apical point 28 and the location of the bottom of the notch 32 whose projection on this axis is closest to that corresponding to the fixed end 22. This so that the finger 23 can pass between the first and second parts 25, 29,

  when the rod 20 is resiliently biased towards the first axis 0-0.

  It should be noted that the only fact that the notch 32 has a depth, may be sufficient to ensure proper operation of the heart cam, without the two edges of the notch 32, in projection on the first axis 0-0, different heights. It is sufficient that the second piece 29 is sufficiently close to the notch 32 to force the finger 23 to enter

  notch 32 as it passes under this second piece 29.

  The position of the slider I for which the finger 23 is housed in the notch 32 and holds the slider 1 against the bias of the spring 300, corresponds to the second stable position C. The third wall 15 is then

  in its stable position closest to the finger 23 (Figure 5).

r Fi-- -

  It will be noted on examining FIG. 5 that after escaping from the apical point 28 of the second piece 29, the finger 23 moves laterally in the notch 32, towards the 0-0 axis, under the effect of the elastic biasing of the rod 20, to come to rest against the second side of the notch 32, close to the axis 0-0 and directed towards the first leg 14. Thus, after this lateral movement, the finger 23 is placed next to the surface

  31 of the second piece 29 and no longer opposite the third face 30.

  In this stable position C, the blade 4 rests against the contact of the high beams 40, since the protuberance 5 of this blade 4 is at a recess 12. By cons, the protuberance 3 of the other blade 2 rests on the support zone 6 and as a result, the dipped beam circuit

  is open at the contact of the dipped beam 50.

  As shown in FIG. 6, when the lever 200 is again actuated, it urges the slide 1 towards the support 100. Now, the rod 20 is shifted laterally (along the axis 0-0) relative to the notch 32 , when it is not constrained, so that the finger 23 leaves the notch 32, thanks to the elasticity of the rod 20, when the slider 1 is brought closer to the support 100 by the lever 200, then that the slider 1 was in the second stable portion C. The rod 20 therefore moves to resume a position where it is neither deformed nor constrained. In this position of the rod 20, the finger 23 projects parallel to the first axis 0-0 and

  direction of the fixed end 22, on the second face 27.

  If the action on the lever 200 is continued, the free end 21 of the

  rod 20 abuts on the third wall 15 of the slider 1.

  If the lever 200 is released, the slider 1 is thrust from the spring 300. The finger 23, now out of the notch 32, comes into contact with the second face 27 (Fig.7). This second face 27 is generally positioned and turned towards the second leg 16, so that the finger 23 slides on it, when the slider 1 is translated from the second C to the first position A stable. The rod 20 then deforms and the finger 23 approaches the second tab 16. But the return force of the spring 300 is sufficient for the pressure and friction of the finger 23 on the second face 27, imposed by this deformation of the rod 20 does not block the translation of the slider 1 to the support 100. Between these two stable positions A, C is a second intermediate position B corresponding to the closure of the two circuits at the contacts of the high beam 40 and the lights of Crossing 50. Indeed, the two protuberances 3, 5 are again, temporarily, in the second intermediate position B, at the recesses 10, 12, which allows the blades 2, 4 to rest on the contacts of the lights. road 40

and low beam 50.

  The slider 1, under the effect of the spring 300, resumes the stable position

  A. A new ABCBA cycle, as described above, can begin again.

  The invention can be the subject of numerous variants.

  According to other variants of the invention, other stable positions of the switch 1 are obtained by arranging the core cams 24 as described above, in cascade. The finger 23 then passes from one heart cam 24 to another by successive actuations and releases.
