Embodiment
Below, describe embodiment of the present utility model in detail with reference to accompanying drawing.Following embodiment provides in order to make those of ordinary skill in the art fully understand content of the present utility model, and it can have various other distortion examples, and protection domain of the present utility model is not to be confined to the following embodiment that will illustrate.
Fig. 1 is the cut-open view under the virgin state of the utility model message input device, and Fig. 2 is the cut-open view under the pressed state of the utility model message input device.
As shown in Figures 1 and 2, the message input device of present embodiment comprises generally: input part 1 and the tactile feedback section 2 that is located on the input part 1.
Wherein, described input part 1 comprises upper electrode 11, lower electrode 12 and microprocessor 13.Described upper electrode 11 is separated preset distance with lower electrode 12 and is oppositely arranged, to such an extent as between described upper electrode 11 and lower electrode 12, form space part 14, and described microprocessor 13 is electrically connected with upper electrode 11 and lower electrode 12 respectively.When the External Force Actings such as finger presses according to the user, when upper electrode 11 contacts with lower electrode 12, microprocessor 13 will be inputted corresponding to the literal of this contact and/or numerical information etc. based on the program of prior setting, with the input operation of this completing user.
Described tactile feedback section 2 comprises the first basalis 21, the second basalis 24, lower conductiving layer 22, upper conductive layer 23, current liquid 25, power supply 26, on-off element 27.Described the first basalis 21 is located on the upper electrode 11 of described input part 1, described the second basalis 24 and the first basalis 21 are separated preset distance and are oppositely arranged, described lower conductiving layer 22 is coated in the upper surface of the first basalis 21 according to modes such as chemical vapor depositions, similarly, described upper conductive layer 23 is coated in the lower surface of the second basalis 21 according to modes such as chemical vapor depositions, and described power supply 26 and described on-off element 27 and upper conductive layer 23, lower conductiving layer 24 are electrically connected.
In addition, the microprocessor 13 of described input part 1 is electrically connected mutually with the on-off element 27 of described tactile feedback section 2, thereby microprocessor 13 can be according to the connecting and disconnecting that whether to contact come gauge tap element 27 (on/off) of upper electrode 11 with lower electrode 12.
At this, described current liquid 25 is known intellectual material, and as a kind of controlled suspending liquid, it is to be scattered in the insulating oil by the micron that can polarize under electric field or nanoscale solids particle to form.These polarizable particles are generally the inorganic particle that contains micro-moisture or high dielectric, perhaps semiconductor high polymer material, thus they polarizedly under DC Electric Field form interconnective chain structure (with reference to the partial enlarged drawing of Fig. 1) along direction of an electric field.The change of this particle disperse state causes current liquid to show the character that is similar to solid aspect rheological properties, that is, and and the instantaneous increase of the appearance of yield stress and shear viscosity.In case the releasing extra electric field, then described particle can be in disperse state (with reference to the partial enlarged drawing of Fig. 2), and current liquid again momentary recovery is liquid.And this moment conversion from liquid to the solid or from the solid to liquid can have the sensation of the vibration of being similar to during by human perception.
