Definitions

  • the present invention relates to a switch device, for automotive, more particularly for a dome control module and the like.
  • Push-type switches with a manually operated push component through which, in turn, a switching component itself is actuated are commercially available as push buttons and as on/off switches or selector switches.
  • the push component Whatever the location of the push component point the manual force is applied on and whatever the location of the point along the push component the plunger is in contact with, the push component will pivot around the hinge. In so doing the push component pushes the plunger which pushes the switch-component downwards.
  • switch devices are known in which the switch device comprises a plunger in contact with the middle of a knob pivotally connected to a housing such that a manual compression of the knob causes the knob to pivots from the outside of the housing of the switch toward the inside and the plunger to move in the same direction.
  • the course of the middle of the knob in a first direction is equal to the course of the plunger in the same direction.
  • switch devices in particular for automotive, can be subject to many customer requirements. These requirements may concern for example the knob shape, the housing shape, the place of the switching component relative to the knob and/or the housing and so on.
  • the invention aims to solve the technical problem of providing an assembly comprising a switch device that will operate respecting customer requirements, and that requires as little built-in space as possible.
  • the invention relates accordingly to an assembly comprising a switch device and a housing, said switch device being disposed relatively to the housing and comprising:
  • the knob does not generate a movement of the plunger toward the switch thanks to a disengagement effect.
  • a potential course difference between the actuation zone of the knob and the plunger is compensated by the present assembly.
  • a ratio one to one between the course of the middle of the knob and the course of the plunger can be respected by this assembly.
  • the assembly may thus be in conformity with design specification coming from various constraints like packaging constraints dictating the location of the knob actuation zone, security constraints dictating the location of the switch and standardization constraints dictating the relative movement of the plunger and the switch.
  • the invention can also comprise any of the following features taken individually or in any technically possible combination:
  • the invention relates to an assembly 1 comprising a switch device 3 and a housing 5.
  • the switch device 3 is disposed relatively to the housing 5.
  • the switch device 3 comprises a switch 30, a plunger 20 and a knob 10.
  • the plunger 20 extends along a first longitudinal axis.
  • the knob 10 is pivotally connected to the housing 5 in such way that the knob pivots around a first rotational axis perpendicular to the sketches on figures 1 and 2 .
  • An actuation zone (M) of the knob 10 is remote from the first longitudinal axis (A).
  • knob 10 In a first position illustrated in figure 1 , the knob 10 is free to move relative to the plunger 20.
  • a manual compression of the knob in a first direction around the first rotational axis (C) on the actuation zone M causes then the knob to come from a first position to a second position. Said second position is not shown on the figures.
  • a further and complete compression of the knob 10 in the first direction causes the knob to come from the second position to a third position.
  • the plunger actuates the switch.
  • the knob In absence of manual compression, the knob returns advantageously to its first position.
  • the knob may return to its first position by a return force transmitted by a return spring.
  • the switch device 3 may be comprised inside the housing 5.
  • the plunger 20 and the switch are inside the housing.
  • the assembly may comprise a bezel 6such that the upper surface of the knob 10 flushes the surface of the bezel 6.
  • the knob's head has a first outgrowth 16.
  • the plunger's head 22 and the knob's head 12 may remain in contact at any position of the knob but without causing a displacement of the plunger 20 between the first and the second position. This allows a better stability of the knob 10 between the first and the third position.
  • the knob's head has also a second outgrowth, said first and second outgrowth forming a groove.
  • the plunger's head 22 slides within the groove between the first and second position. It is then in contact with a bottom of the groove in the second position and between the second and third position.
  • the groove allows an even more enhanced stability of the knob 10 between the first and the third position.
  • the plunger's head 22 may have a particular shape that helps to reduce the possible mechanical constraints caused by the compression of the knob.
  • the plunger's head 22 is curved.
  • the plunger's head 22 may have in section the shape of a half radius.
  • the plunger's head has a complementary form to said groove.
  • the plunger is made of one single component. More precisely, the plunger's head and is here integral with plunger body.
  • a second longitudinal axis (B) is parallel to the first longitudinal axis (A) and passes by the middle of the knob 10.
  • the plunger may be located inside a shaft 52 located remotely from the second longitudinal axis (B). Said shaft helps to control the translation movement of the plunger between the second and the third position and to improve the stability of the assembly.
  • Said plunger body is located in said shaft 52.
  • Said shaft 52 is a part of the housing 5.
  • Said plunger body comprises an end in abutment on said switch.
  • the first rotational axis (C) may be defined by protrusions on both sides of the knob 10 cooperating with holes formed on lateral sides of the housing.
  • said first rotational axis (C) may be defined by a hinge 54. Said hinge helps to prevent any removing of the knob 10 from the housing 5.
  • each point of the knob is moving along a circle whose center is defined by the first rotational axis (C).
  • the radius of the circle depends on the distance between the first rotational axis (C) and the point of the knob. The farther the point of the knob is from the rotational axis (C), the larger the radius of the circle.
  • the angular stroke of the knob 10 between the first and the second position does not involve a first stroke of the plunger's head 12. Indeed, as already said, between the first and the second position, the knob 10 is free to move relative to the plunger 20.
  • the angular stroke of the knob 10 between the second and the third position involves a second stroke of the plunger's head 12. Said second stroke will be transmitted to the plunger as, between the second and the third position, the knob 10 is in moving abutment on the plunger 20.
  • the angular stroke of the knob between first and second position is for instance comprised between 4 and 8°.
  • the distance between the point M in the first position and the orthogonal projection of the point M on the second longitudinal axis (B) in the third position is inferior to the distance between a point on the knob's head 12 in the first position and the orthogonal projection of said knob's head point on the first or second longitudinal axis in the third position.
  • the depth of the groove formed by the two outgrowths 16, 18 allows compensating the course difference between the actuation zone M of the knob 10 and the plunger 20.
  • the distance between the point M in the first position and the orthogonal projection of the point M on the second longitudinal axis (B) in the third position is the same distance as the distance between the orthogonal projection of a point of the plunger in the first and the third position. This allows keeping a ratio one on one between the course of the middle M of the knob 10 and the course of the plunger 20.
  • intersection point I The intersection between said second longitudinal axis (B) and the PCB defines an intersection point I.
  • said intersection point I is at most at 3mm from the closest edge of the PCB according to electrical circuitry security rules.
  • a longitudinal distance between the first rotational axis and an upper surface of the PCB is comprised between 10mm and 20mm, more preferably between 13mm and 15mm.
  • FIG. 3 shows a dome control module 2 according to the invention.
  • Said dome control module comprises an assembly 1 according the invention.
  • the switch device of said assembly may comprise any of the technical features described hereinabove.
  • the bezel 6 may represent the largest part of the dome control module seen by a user.
  • the bezel 6 may be made of a material nobler than the rest of the housing 5 so as to improve the finish of the dome control module perceived by a user.
  • the dome control module may be located on the ceiling of a vehicle, between the two front seats and aligned with the central mirror.
