Title (EN) HAPTIC KNOB, IN PARTICULAR FOR AN ELECTRIC OR ELECTRONIC APPARATUS, FOR EXAMPLE A HOUSEHOLD APPLIANCE
(FR) BOUTON HAPTIQUE, EN PARTICULIER POUR UN APPAREIL ÉLECTRIQUE OU ÉLECTRONIQUE, PAR EXEMPLE UN APPAREIL ÉLECTROMÉNAGER
Abstract:
(EN) The knob (10) comprises: a support structure (12) defining a chamber (15) containing a magnetorheological fluid; a holding element (11) which is supported in a guided manner by said support structure (12) and is configured to be rotated and pressed by said user; a movable portion (13) which is supported, in its rotation, by the support structure (12) and is configured to be controlled, in its rotation, by the holding element (11); a switching member (26) which is movable from a rest arrangement to a work arrangement when said holding element (11) is pressed by the user; a sensor (23) which is configured to detect the angular position assumed by the movable portion (13); a haptic feedback assembly (14) which is located in the chamber (15) and is configured to act upon the movable portion (13) so as to provide a haptic stimulation in response to the action of the user; a generating apparatus (16) which is configured to emit a magnetic field, whose intensity is capable of affecting the viscosity of the fluid in such a way that said assembly (14) exerts a force upon the movable portion (13); and a control device (21) which is configured to determine the intensity of said magnetic field depending on predetermined or programmable criteria which are based on at least one between the angular position and the arrangement.
(FR) L'invention concerne un bouton (10) comportant: une structure de support (12) définissant une chambre (15) contenant un fluide magnétorhéologique; un élément de maintien (11) ayant un support guidé par ladite structure de support (12) et qui est configuré pour être entraîné en rotation et pressé par ledit utilisateur; une partie mobile (13) qui est maintenue, lors de sa rotation, par la structure de support (12) et est configurée pour être commandée, lors de sa rotation, par l'élément de maintien (11); un élément de commutation (26) qui est mobile depuis une position de repos jusqu'à une position de travail lorsque ledit élément de maintien (11) est pressé par l'utilisateur; un capteur (23) qui est configuré pour détecter la position angulaire prise par la partie mobile (13); un ensemble de rétroaction haptique (14) qui est situé dans la chambre (15) et qui est configuré pour agir sur la partie mobile (13) afin de fournir une stimulation haptique en réponse à l'action de l'utilisateur; un appareil générateur (16) qui est configuré pour émettre un champ magnétique, dont l'intensité est apte à affecter la viscosité du fluide de sorte que ledit ensemble (14) exerce une force sur la partie mobile (13); et un dispositif de commande (21) qui est configuré pour déterminer l'intensité dudit champ magnétique en fonction de critères prédéterminés ou programmables qui sont basés sur au moins une parmi la position angulaire et l'agencement.
