Actuator for tact interface module, tact interface module and method for generating tactile feedback

摘要

The present invention is connected to a frame (11) intended to contact a tact interface via a contact wall (13) and to said frame (11) for transmitting tactile feedback to the tact surface. A stator (15) and a movable connected to the chassis (11) via at least one elastic element (21) and intended to be moved by the stator (15) to generate haptic feedback A core (19), an electromagnet (17) and at least one permanent magnet (20), one supported by the stator and the other supported by the movable core (19); An actuator (7) comprising at least one permanent magnet (20). The actuator (7) also has a shock absorber (23) disposed between the movable core (19) and the contact wall (13), and the elastic element (21) is formed by the electromagnet. In a state where no power is supplied, the movable core (19) exerts a supporting force toward the contact wall (13), and in a state where the electromagnet is supplied with power according to a predetermined polarization, the movable core (19) It is dimensioned to be separated from the contact wall (13).
