Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to according to its embodiment of anti-vibration and shock pad, structure, feature and the effect thereof that the utility model proposes, describe in detail as after.
See also Fig. 1 to shown in Figure 5, Fig. 1 is an embodiment's of the present utility model plan view, Fig. 2 be among Fig. 1 along the sectional view of A-A line, Fig. 3 is along the sectional view of B-B line among Fig. 1, Fig. 4 is the utility model embodiment's a erection drawing, and Fig. 5 is the utility model embodiment's a exploded perspective view.The anti-vibration and shock pad that the utility model embodiment proposes, it mainly comprises: support body 1, ccontaining 2 of electrorheological fluid, piezoelectric element 3 and first cover plate, 6 second cover plates, 6 ｀.Wherein:
Ccontaining 2 of electrorheological fluid comprises the porous material as carrier, and is adsorbed in the electrorheological fluid within the porous material.Wherein, this porous material is selected the material of quality softness, as foamed plastics, sponge etc.Electrorheological fluid (electrorheological fluid ER) is a kind of intellectual material, the uniform particles with high-k by micron (nanometer) yardstick is dispersed in the oil-phase medium of insulation low-k, form suspension, when applying external electric field, the ER fluid transfers the class solid state to from flowing state, its apparent viscosity surge several magnitude, and to reach this process of higher shear stress be reversible, controlled, (Millisecond) and low power consumption fast can be used for efficiently solving the protection question of mechanical shock.The shape that electrorheological fluid is ccontaining 2 is identical with the inner space shape of above-mentioned support body 1, so that can be placed in wherein with mechanical engagement.
So the anti-vibration and shock pad that constitutes of said structure is softer when static state, in case but its meets with dynamic loading---mechanical vibration or it is fallen earthward, and its rigidity, hardness will change with external load, and damping also can change and improve.Because piezoelectric element 3, accept the outside and fall load, will produce electromotive force, by positive and negative electrode, with first cover plate 6 and second cover plate 6, conductive layer UNICOM produce electric field, ccontaining 2 of electrorheological fluid is arranged in this electric field, then the viscosity of electrorheological fluid raises immediately, hardness of foamed plastics or sponge and damping are risen, and ccontaining 2 of electrorheological fluid increased rigidity, hardness, and changes (Millisecond) with load fast with rule.Make vibration, impact, fall response that load causes and be absorbed rapidly or decay.
Any zone of electronic equipment can be laid or stick on to the anti-vibration and shock pad of the foregoing description, as shown in Figure 6, is a plurality of anti-vibration and shock pads 110 non-uniform examples that one of mount on Laptop case 100.Can the key area of notebook computer be protected according to actual conditions, can be at the fixing a plurality of anti-vibration and shock pads in the zone of needs.Also can the element of specific (special) requirements such as hard disk, be had relatively high expectations to vibration damping, can add or fill up this anti-vibration and shock pad near the hard disk.Because the anti-vibration and shock pad is intelligent, can absorbs, consume external vibration with a definite target in view and impact the energy that falls load, the protection hard disk.Certainly, also can stick the anti-vibration and shock pad to the display screen LCD back side, according to the load characteristics, emphasis solves the harm of external force to LCD targetedly.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model with the preferred embodiment introduction as above, yet be not in order to limit the utility model, any those skilled in the art, in the scope that does not break away from technical solutions of the utility model, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solutions of the utility model content, foundation technical spirit of the present utility model is to above any simple modification that embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
