It relates to a damper device, an electronic product and a portable device used.

Smart materials such as controllable fluids are materials whose viscosity of the liquid itself varies in response to an externally applied electric or magnetic field. And the controllable fluid is roughly classified into an electrorheological fluid reacting to an electric field and a magnetorheological fluid reacting to a magnetic field.

In recent years, such controllable fluids have been increasingly used to provide haptic effects in portable devices (for example, smart pads), as actuators for robots, as tactile transmitters, or as dampers.

However, due to the disadvantage that the controllable fluid has a small area where the viscosity increases in response to the electric or magnetic field, and the power consumption is high because a strong electric or magnetic field is required to change the viscosity of a large amount of the controllable fluid as a whole.

<Configuration of resistance generating module>

The present invention relates to a resistance generation module that transmits resistance to a user by using a controllable fluid that is a magnetorheological fluid or an electrorheological fluid. The present invention relates to a complex mode such as a flow mode, a shear mode, or a squeeze mode to generate such a resistance force. Can be used.

Hereinafter, the configuration of the resistive force generating module according to the present invention will be described in detail with reference to FIGS. 1 to 17.

First, FIGS. 1 to 3 show an operation mode of an electrorheological fluid or a magnetorheological fluid. 1 is a flow mode (Flow Mode) is a mode that generates a flow resistance force as the fluid flows in a direction perpendicular to the direction of the magnetic field, that is, left / right. FIG. 2 is a shear mode in which a shear resistance force is generated as the upper plate moves in a left / right direction in a direction perpendicular to the direction of a magnetic field. 3 is a squeeze mode (Squeeze Mode) is a mode for generating a squeeze resistance as the upper plate moves up and down in a direction parallel to the direction of the magnetic field.

On the other hand, Figures 4 to 5 is a view of reducing the strength of the magnetic field according to the separation distance between the upper plate and the lower plate. As shown in FIG. 4, when the distance between the upper plate and the lower plate made of ferromagnetic material is x, a magnetic field of about 1000 Guass is formed. When the distance between the upper plate and the lower plate is 2x, as shown in FIG. 5, the magnetic field of about 300 Guass is shown. Is formed. Therefore, when the distance between the upper plate and the lower plate is 2 times, it can be seen that the intensity of the magnetic field of about 1/3 or more is reduced. Since the strength of the magnetic field is influenced by the distance, the resistance generating module that can be used with less influence by the distance will be described in the present invention.

On the other hand, the squeeze mode of the above-described composite mode can generate the largest force under the magnetic field of the same intensity, it can be used particularly effectively when designing a damper of a small size.

Hereinafter, the squeeze mode will be assumed. However, the resistance generating module according to the present invention can be used in combination with the above-described flow mode or shear mode.

The fluid according to the invention uses an electrorheological or magnetorheological fluid. In this case, when the magnetic field is formed, a magnetorheological fluid is used, and when an electric field is used, an electric rheological fluid is used. The above-described fluid is filled in the space between the first slope 200 and the second slope 300 to be described later to generate a resistance force.

Here, the magnetorheological fluid is one of intelligent materials as a material in which the viscosity characteristic of the fluid is reversibly changed according to the strength of the magnetic field. Specifically, the magnetorheological fluid includes iron, nickel, cobalt, and magnetic alloys of fine particles having a diameter of several to several tens of microns in a dispersion medium such as mineral oil, synthetic hydrocarbon, water, silicone oil, and esterified fatty acid. Refers to a dispersed noncolloid suspension.

On the other hand, the magnetorheological fluid has a large variation in flow characteristics such as viscosity characteristics of the fluid as the magnetic field is applied, and excellent durability. In addition, they are relatively less sensitive to contaminants and are very fast and reversible to magnetic fields. Because of this property, it is considered to have great applicability in various industrial fields such as vibration control devices such as clutches of automobiles, engine mounts, dampers, high-rise seismic devices, and driving devices of robotic systems.

In addition, the magnetorheological fluid 20 exhibits properties of Newtonian fluid when no magnetic field is applied. However, when a magnetic field is applied, the dispersed particles form a dipole to form a fibrous structure in a direction parallel to the applied magnetic field, and the fibrous structure increases the viscosity and thus has a shear force or a resistance to flow that interferes with the flow of the fluid. Increase the yield stress much. At this time, the yield stress increases with the strength of the magnetic field.

On the other hand, the electrorheological fluid is a fluid whose viscosity changes depending on the electric field. In other words, the electro-fluidic fluid is a suspension in which highly polarized particles are dispersed in an insulating fluid, and when the electric field is absent, it is in a low viscosity state and is changed into a high viscosity state such as hardened when applied to the electric field. That is, when the rheological fluid becomes high viscosity, the user feels tactile feedback.

On the other hand, the rheological fluid has a sharp increase in viscosity since particles are arranged in a chain-like structure in the direction of the electric field under the influence of an applied electric field. Such electrorheological fluids increase in viscosity in proportion to the intensity of the applied electric field. Electrorheological fluids have the advantages of high tensile and low viscosity, stiffness, stability and wide temperature range, making them suitable for tactile applications.

A schematic component of such an electrorheological fluid consists of polyaniline / titanium dioxide composite as conductive particles. That is, the electro-fluidic fluid 30 is prepared by dispersing an organic-inorganic composite compound of polyaniline, which is a conductive polymer, and titanium dioxide having a high dielectric constant, in a non-conductive solvent. In this case, the degree of polarization increases the electric rheological effect, and since the use of organic and inorganic particles as the conductive particles, there is an advantage that can operate without obstacles of temperature or external environment. More specifically, the electro-fluidic fluid 30 is a polyaniline / TiO ₂ organic-inorganic composite in which the amount of TiO ₂ particles is 15 to 35 wt% based on the polyaniline as conductive particles.

The generating means 100 according to the present invention is a means for generating an electric or magnetic field. That is, to generate an electric field, an electric field is generated by applying a voltage to an electrode having a positive / negative polarity. At this time, the intensity of the electric field can be adjusted by controlling the magnitude of the current applied to the electrode.

In addition, the generating means 100 may generate a magnetic field by generating a magnetic field using a solenoid coil or the like to generate a magnetic field. At this time, the strength of the magnetic field can be adjusted by controlling the magnitude of the current applied to the solenoid coil, the direction of the magnetic field can be adjusted by switching the direction of the current.

The first inclined plane 200 and the second inclined plane 300 according to the present invention are inclined planes through which an electric or magnetic field flows. In this case, the second slope 300 is positioned to face the first slope 200.

As a first embodiment of the first and second inclined surfaces 200 and 300 and the force transmission means 400 to be described later, as shown in FIG. 6, the first and second inclined surfaces 200 and 300 are inclined at an angle of θ. Lose. Thus, as shown in FIGS. 6 and 7, even if the distance between the force transmission means 400 and the lower plate 30 made of a ferromagnetic material moves from X to 2X, the first inclined surface 200 and the first boundary surface 410 are separated. The distance of is separated from Ysinθ to Ysinθ + Xsinθ, it can be seen that it can be used in squeeze mode. More specifically, since Xsinθ always has a smaller value than X, even if the vertical distance increases from X to 2X, the separation distance between the first and second inclined surfaces 200 and 300 and the force transmission means 400 becomes Ysinθ + Xsinθ to compensate for the separation distance. It becomes possible.

Meanwhile, the generated magnetic or electric field always flows in a direction perpendicular to the first and second slopes 200 and 300 as shown in FIG. 8. As shown in FIG. 9, the magnetic field always flows in a direction perpendicular to the inclined plane even if the direction in which the magnetic field is generated is changed.

The first and second slopes 200 and 300 described above may form inclined surfaces using one ferromagnetic material, or may form respective inclined surfaces using two ferromagnetic materials.

The force transmission means 400 according to the present invention is inserted to form a space between the first slope 200 and the second slope 300. That is, the first inclined plane 200 and the first boundary plane 410 face each other at a predetermined distance, and the second inclined plane 300 and the second boundary plane 420 face each other at a predetermined distance. Accordingly, the first slope 200 and the first boundary plane 410 are relatively parallel to each other, and the second slope 300 and the second boundary plane 420 are also relatively parallel to each other.

Meanwhile, the force transmission means 400 inserted between the first and second slopes 200 and 300 is pressed in the vertical direction (up / down direction) by the user's force, and between the first and second slopes 200 and 300. Resistant force is generated by the filled fluid to transmit the resistance to the user.

The cross-sectional shape of the force transmission means 400 described above is tapered in the direction in which the force transmission means 400 is pressed. That is, the area decreases from the upper direction to the lower direction to which the user's force is applied. Accordingly, first and second boundary surfaces 410 and 420 corresponding to the first and second slopes 200 and 300 are formed.

Meanwhile, as the second embodiment of the first and second slopes 200 and 300 and the force transmission means 400 which will be described later, the first and second slopes 200 and 300 may include the upper slopes 210 and 310 and the center slope. 220 and 320, and inclined surfaces of the lower slopes 230 and 330 are formed.

In addition, the cross-sectional shape of the force transmission means 400 is a shape tapered from the center to the upper direction, and also a shape tapered from the center to the downward direction. That is, the overall shape of the force transmission means 400 is a shape in which the center is convex and the area decreases from the center toward both ends.

Therefore, the upper slopes 210 and 310 and the lower slopes 230 and 330 form inclined surfaces corresponding to the shapes of the force transmission means 400 described above. However, the center slopes 220 and 320 may not be inclined surfaces as shown in FIG. 10.

As described above, the distance between the force transmission means 400 and the lower plate 30 made of a ferromagnetic material as shown in FIGS. 10 and 11 by the formation of the force transmission means 400 and the first and second slopes 200 and 300. Even if we move away from X to 2X, we can compensate for the separation distance from each other. That is, the distance between the upper inclination 210 and the first 'boundary surface 430 is reduced from Ysinθ + Xsinθ to Ysinθ, while the distance between the lower inclination 230 and the second' boundary plane 400 is Ysinθ + Xsinθ from Ysinθ. As a result, the separation distance is slightly increased to compensate for the mutual separation distance. It can be seen that this embodiment is different from the first embodiment shown in Figs.

As shown in FIGS. 12 and 13, the magnetic field tends to flow toward the side where the resistance is smaller, that is, the separation distance between the first and second slopes 200 and 300 and the force transmission means 400 is closer. Therefore, the strength of the magnetic field is affected by the separation distance of the ferromagnetic material, so when the magnetic field flows closer to the separation distance, even greater resistance can be generated by the same magnetic field strength. However, the above-described phenomenon is equally applicable to the case where an electric field is formed.

On the other hand, Figure 14 is a view in which the fluid according to the invention forms a chain in parallel to the direction of the magnetic field. However, even in an electric field, the fluid forms a chain parallel to the direction of the electric field.

As shown in FIG. 15, a plurality of resistive forces may be generated by forming a chain of fluid in parallel with the direction in which the magnetic field or the electric field is formed.

That is, the squeeze resistance is the resistance generated in the squeeze mode described above. As shown in FIG. 15, when a chain of fluid is formed by a magnetic field, a resistance force F ₀ is generated by the magnetic force. In this case, the squeeze resistance is a resistance corresponding to F ₀ cosθ.

On the other hand, the flow resistance is a resistance generated in the above-described flow mode, the shear resistance is a resistance generated in the above-described shear mode. As shown in FIG. 15, the flow resistance force and the shear resistance force are resistance forces corresponding to F ₀ cosθsinθ. However, the above-mentioned resistance is the same in the case of an electric field.

FIG. 16 illustrates a diagram in which magnetic fields flow in the first and second inclined surfaces 200 and 300 when the generating unit 100 forms a magnetic field using a solenoid coil, and FIG. 17 illustrates that the generating unit 100 uses different electrical polarities. In the case where the electric field is formed, the electric field flows through the first and second inclined surfaces 200 and 300.

In this case, when the magnetic field is formed, the fluid is used as a magnetorheological fluid, and when the electric field is formed, the fluid is used as an electrorheological fluid.

Here, the step S630 will be described in more detail. First, the squeeze resistance 21 is generated as follows. The fluid forms a chain in the direction of the generated electric or magnetic field. Next, the squeeze resistance 21 is generated in parallel with the direction in which the force transmission means 400 moves in accordance with the chain formation of the fluid. In this case, the squeeze resistance is F ₀ cosθ as shown in FIG. 15. Next, the force transmission means 400 receives the generated squeeze resistance (21).
