Definitions

  • the invention relates to a multifunction satellite key for motor vehicle dashboard.
  • dashboards used in motor vehicles rarely use the concept of one-piece multi-function button.
  • a example is that of the dashboard of the vehicle marketed by the French company "Peugeot" under the name “206 electronic".
  • the multifunction key system used has only two control positions and its design appear to be more than aesthetic considerations as a priority search for reduction of volume of all control buttons.
  • the invention proposes to provide a satellite touch multifunction for motor vehicle dashboard allowing the reduction of the volume of the dashboard and its integration into a confined space.
  • Another object of the present invention is to limit the number of parts used in the manufacture of the satellite button multifunction, thus facilitating its assembly and reducing its cost.
  • the first part spherical of the facade forms a spherical housing in which articulates the second spherical part of the transmitter thus forming the connection to patella.
  • the first spherical part of the facade is a core with a spherical outer wall
  • the second spherical part of the transmitter is an inner wall ring spherical hinging on the first part to form the ball joint.
  • the transmitter assembled integrally with the lens can be fixed on the facade.
  • the cabochon is assembled integrally on the transmitter with the facade interposed between them.
  • the transmitter includes pushers to activate push buttons or blisters.
  • the satellite button advantageously includes a means of backlight.
  • the satellite button comprises a chicane defined by a rim of the cabochon cooperating with a skirt formed at level of a rim of the opening of the facade so as to oppose the scattering of light through peripheral games of the button satellite.
  • Order locations can correspond to several of the following functions: air distribution, ventilation, air conditioning, data reading (cassette or CD player), car radio, navigation, telecommunications, reception-transmission of data, intensity setting.
  • the transmitter is movable according to four particular pivoting movements corresponding to four function control slots particulars controlled by the satellite button.
  • control locations are assigned to two mutually incompatible particular functions, the other two control slots for increasing or to decrease by pulse the value of the activated function among said two special functions.
  • said activated function is displayed by a light.
  • Figures 4 to 5B as well as Figures 6 to 8C correspond to different variants of satellite touch which include each a series of constituent elements whose geometry can be different from one embodiment to another, but whose function is the same. Elements having essentially the same function have the same reference numbers.
  • Figure 1 illustrating a front view of a multifunction satellite key 100 for motor vehicle dashboard.
  • the Figure 1 satellite button defines four control locations 131 associated with ventilation, air conditioning, distribution functions air and defrost.
  • control locations 131 associated with ventilation, air conditioning, distribution functions air and defrost.
  • other functions can be combined at the command locations, among which: reading for recording data, for example a cassette player or CD, radio, navigation, telecommunications, reception-transmission of data, intensity setting, etc.
  • FIG. 2 is an exploded perspective view of the key satellite 100 of FIG. 1, illustrating a particular embodiment.
  • the satellite button 100 has a front panel 110, a mobile transmitter 120, a cap 130 and an electrical circuit 140.
  • the facade 110 has an opening 111 whose outline 115 has the shape of a curved cross (or a four-leaf clover).
  • facade 110 has a first part spherical defining a spherical housing 112 and supported by arms 113 which connect the spherical part 112 to the facade 110 and delimit sectors 114 associated with the respective specific functions.
  • the arms 113 can be stiffened by reinforcements 113a.
  • the facade 110 also includes tabs 116 projecting perpendicularly to the arms 113 of the facade 110 around the spherical housing 112. Furthermore, guide ducts 117 are carried by the facade 110, at the tops of the lobes of the contour 115 of the opening 111. In addition two guide sheaths 117 diametrically opposite carry two guide pins 118.
  • a pusher 121 is flexibly linked to the periphery of each open ring 123.
  • the transmitter 120 is plugged into the front panel 110 on the one hand, in locking the second spherical part 122 by the tabs 116 of the facade 110 and on the other hand, by engaging the pushers 121 of the transmitter 120 in the corresponding sheaths 117 of the facade 110 while being guided by the guide pins 118.

Due to its ergonomics, the cabochon 130 allows unambiguous symbolism for functions the satellite button 100, thus avoiding any incorrect use, such as for example pressing simultaneously on two control positions different. As shown more particularly in FIG. 2B, the transmitter 120 is integrally assembled with the cap 130 by engagement and locking of projecting parts 125, forming clips, located on the exterior face of the transmitter 120 in slots 135 formed on the internal side of the cabochon 130.
  • the correct positioning of the cabochon 130 bearing the symbolism of the functions ordered is provided by polarization means formed by lugs 124 of the transmitter 120 who engage in corresponding housing 134 of the cabochon 130.
  • the cap 130 and the transmitter 120 are assembled from together and form a single body.
  • the transmitter 120 being fixed on the front 110 by in particular through the tabs 116 forms a ball joint by assembling the first spherical part 112 of the facade 110 with the second spherical part 122 of the transmitter 120.
  • the connection to ball thus formed is limited in its movement and is equivalent to a plurality of pivotal connections around coplanar axes in the plane of the facade 110 and concurrent in the center of the ball joint.
  • the cabochon-transmitter assembly is not mobile in rotation around of an axis perpendicular to the facade 110 and remains movable relative to the facade 110 only according to a limited number of movements of pivoting at low amplitude, so as to define the locations of command 131 symbolized on the cabochon 130.
  • Non-floating mounting of the cabochon-transmitter assembly on the facade 110 ensures good vibration resistance and guarantees unambiguous control of the desired function.
  • the electrical circuit 140 is fixed behind the facade 110 and comprises a plurality of push buttons or blisters 141 protected by a silicone membrane and corresponding to the plurality of positions of command 131.
  • the push buttons or blisters 141 are actuated by via pushers 121 whose pushing force is transmitted by the pivoting of the cabochon-transmitter assembly. Being related to flexibly to the transmitter 120, the pushers 121 remain guided by their sheaths 117 perpendicular to the electrical circuit 140 during a pivoting of the transmitter 120. However, the pushers 121 can be separated from the transmitter 120 by breaking, without altering the correct operation of the device. The fact that they were part of the transmitter 120 satisfies the goal of reducing the number of parts to to assemble.
  • the electrical circuit 140 also includes a backlight means 142 consisting, in the example of FIG. 1, of a plurality of diodes 142 corresponding to the plurality of sectors 114 delimited by the arm 113 of the facade 110.

  • the pushers 121 can exert a small preload on pushbuttons or blisters 141.
  • the multifunction satellite button 100 has a baffle defined by a rim 132 of the cabochon 130 opposite a skirt 119 formed by a edge of the opening 111 of the facade 110.
  • the light from the diodes 142 which lights up symbols on the cabochon 130, through the rings open 123 of transmitter 120, does not diffuse through games present between the cabochon 130 and the periphery of the opening of the facade 110.
  • Figure 3B is a sectional view illustrating a satellite key 100 in an activated mode.
  • the cabochon-transmitter assembly pivots while driving via a push button 121 actuation of a push button or blister 141 which in turn activates the particular function which is its associated.
