Definitions

  • the present invention relates to a stimulation method making it possible to generate on the finger of a user who acts on a key of a static keyboard, a determined tactile effect, for example in order to recreate a feeling of effort and similar break to that provided by conventional push buttons (in particular of the type with deformable capsule).
  • a static keyboard usually comprises a rigid surface possibly mounted on a force measurement system and covered with a so-called “tactile” surface making it possible to make and locate the selections.
  • This keyboard can also comprise a grid for guiding the supports and for delimiting the zones constituting the keys, this grid being attached to the touch surface or integral with it.
  • the invention more particularly aims to eliminate these drawbacks.
  • the above threshold value may possibly be determined so that the movement of the movable part begins at the time of the change of state of the switching circuit associated with the key which is pressed, or even after a period of determined time following this change of state, for example a period necessary for the validation of said change of state.
  • the method according to the invention further comprises a return of the mobile part to its initial position, either after a determined period ⁇ following the change of state, or following the release of the key by the operator.
  • a device for implementing the method described above will necessarily involve: - a static type keyboard comprising a plurality of keys; - a mobile equipment including all or part of the keyboard; - Detection means able to detect at least one of the components of the stresses experienced by the keyboard following the action of an operator on a key on the keyboard; - An actuator able to generate a predetermined movement of the movable assembly; and an electronic circuit ensuring control of the actuator as a function of the signal delivered by the detector and / or of the state of the switching device associated with the key of the keyboard which has been pressed.
  • the keyboard comprises a movable assembly 1 including a flat support 2 carrying a touch surface 3 and a grid 4 for guiding the supports and delimiting the areas serving as keys 5.
  • a movable assembly 1 including a flat support 2 carrying a touch surface 3 and a grid 4 for guiding the supports and delimiting the areas serving as keys 5.
  • the tactile structure could be incorporated into the support 2.
  • this support 2 could possibly consist of a liquid crystal cell to ensure relegendable identification of the keys 5.
  • the guide means comprise rolling elements 9, 9 ′ mounted on two respective rolling tracks 10, 11.
  • the component F ⁇ (normal to the touch surface) of the forces F applied by the user to the keys is detected by means of a force detector D placed under the raceway 10.
  • the movements of the mobile assembly 1 according to the double arrow 7 are controlled by an actuator module 12 constituted by a double-acting electromagnet comprising a holding winding 13, a traction winding 14, and a mobile armature 15 connected to the mobile equipment 1 via a transmission device.
  • an actuator module 12 constituted by a double-acting electromagnet comprising a holding winding 13, a traction winding 14, and a mobile armature 15 connected to the mobile equipment 1 via a transmission device.
  • This transmission device here comprises a link 16 whose ends are respectively articulated on said frame 15 and on said equipment 1 and whose central part is pivotally mounted around a fixed axis 17.
  • the excitation of the coils 13, 14 is controlled by a computer 18 which also receives information from the selection location devices, associated with each key 5, and the detection signal from the force detector D.
  • the actuator 12 could be produced using two electromagnets (EAT traction and EAM holding) mounted in tandem and having movable armatures or cores mechanically coupled to each other.
  • the role of the actuator 12 is more particularly: . to keep the moving element 1 in the rest position as long as the selection is not taken into account by the computer 18 is not effective, by opposing any movement due to a force exerted by the operator's finger; . releasing the moving element 1 and moving it in the direction of the force F exerted by the operator, when the selection has been taken into account by the computer 18.
  • FIGS. 2 to 5 The operation of the keyboard described above is more particularly illustrated in FIGS. 2 to 5.
  • the holding winding 13 of the actuation module 12 is energized, the movable armature 15 is in the position for which the air gap formed between the fixed frame associated with the winding 13 and the movable frame 15 is minimum. The retaining force generated by this winding 13 is then maximum.
  • the traction winding 14 of the module 12 is not supplied; the air gap between the fixed frame associated with this winding 14 and the movable frame 15 is maximum and corresponds to the maximum stroke of the movable frame 15.
  • the operator places his finger on a key and exerts an increasing pressing force F.
  • the computer 18 determines that the selection is not effective and therefore maintains the rest state.
  • the force exercised exceeds a preprogrammed threshold F1 ( Figure 3) which here corresponds to the detection threshold S of the operated key ( Figure 2).
  • the computer 18 determines that the selection is effective and causes the movement of the moving element 1 by cutting the supply of the holding winding 13 and by establishing the supply of the traction winding 14. It should be noted that this process could also be triggered, either in response to the exceeding of the detection threshold S (and, consequently, of the change of state of the switching circuit associated with the key 5 pressed), or when a logical combination, for example of the AND or OR type of the two trigger conditions mentioned above, is performed.
  • the excitation of the traction winding 14 causes the mobile armature 15 to move until, at the end of the travel, the air gap between the fixed armature associated with the winding 14 and the mobile armature 15 be minimal.
  • This displacement of the movable armature causes a corresponding displacement of the movable assembly 1 along a stroke which is equal to the product of the stroke of the movable armature 15 by a multiplication (or demultiplication) coefficient determined by the ratio of the lengths of the two arms b1, b2 of the link 16.
  • the moving part 1 is then maintained in this excited state for a period ⁇ determined by the computer 18, either by programming, or by detection of an instant t2 marking the end of the period ⁇ which corresponds to the moment when the operator releases the selected key.
  • This determination of the instant t2 can be ensured, either from the change of state of the switching circuits associated with the pressed key 5, or from the passage of the detected force. by detector D below a certain threshold F2 ( Figure 3).
  • the computer 18 causes the traction winding 14 to become de-energized and the holding winding 13 to be excited, so that the moving element 1 returns to the rest position.
  • a return spring 20 can also be provided to facilitate this return and to place the mobile assembly 1 in the rest position, in the absence of supply to the computer 18.
  • Figures 6 and 7 show the similarities between the sensations obtained using a keyboard according to the invention and those obtained using a conventional button.
  • the arrow f indicates the location of the stroke of the key corresponding to the taking into account of the selection.
  • the movable assembly 1 moves in translation along an axis parallel to the touch surface 3, which is then preferably oriented so that the force exerted by the finger of the operator on a key 5 is oriented obliquely to said axis of movement.
  • the force F has, in the plane of the tactile surface 3, a component F 'tending to bring the mobile assembly 1 to the excited state, to against the action exerted by the spring 20 and the attraction due to the excitation of the retaining winding 13. Thanks to these features, it becomes possible to suitably adjust the tactile effect generated by the keyboard on the operator's finger.
  • the moving element 1 could be mounted on the fixed structure 6 as shown in FIG. 8, so that it moves in translation along an axis X perpendicular to the plane of the touch surface 3 and, preferably, parallel to the pressing force F exerted by the user's finger.
  • the actuation module 12 is then designed so as to ensure the translation of the movable assembly 1 along the above-mentioned axis of movement X and according to the previously defined sequence, in order to restore the sensation of a pusher which gives way under support.
