The through hole 3321 is formed in the longitudinal direction, and the second roller 325 and the resistance module 324 may be inserted into the through hole 3321 of the third inner housing 323. In addition, an outer housing 329 may be disposed on a lower surface of the third inner housing 323 to prevent separation of the roller 327, and the outer housing 329 may have a through hole formed in the longitudinal direction of the second shaft 321. ), The roller 327, the power transmission cam 328 and the armature 326 is seated in the through hole. In addition, the external housing 329 may have a third gear 3291 formed on the lower surface thereof, and may also be provided in a form in which the third gear 3291 may also rotate as the external housing 329 rotates.

As shown in FIG. 6, 7, or 8, the resistance module 324 may change the relative rotational speeds of the outer housing 329 and the armature 326 to attach and detach the roller 327 to the outer housing 329. Or refers to a module that performs the function of attaching. To this end, the resistance module 324 according to an embodiment of the present invention may be provided in various forms, as shown in FIG. 6, 7, or 8.

As shown in Figure 6, the resistance module 324 according to an embodiment of the present invention is formed in the form of a friction plate in which the plurality of second roller 325, which may be provided in a plurality, spaced apart, the armature 326 by friction You can change the speed of). More specifically, it includes a third internal housing 323, the second rotational transmission unit 324 and the second roller 325, to generate a frictional resistance to the rotation of the armature 326, through which the power unit 300 The rotation speed is transmitted through the rotation force difference between the power transmission cam 328 and the armature 326 can be generated. To this end, the resistance module 324 is formed of a material having a restoring force, thereby reducing the rotational speed of the second roller 325, that is, the rotational speed of the armature 326.

The second roller 325 and the second rotation transmission unit 324 is a configuration that rotates by receiving a rotational force from the armature 326, based on the configuration of the resistance module 324 shown in FIG. 3 may be inserted into the through hole 3321 of the internal housing 323. Like the roller 327, the second roller 325 may be formed in a cylindrical shape, one surface of which may be in contact with the power unit connecting portion 322, and the other surface of which may be in contact with the armature 326. At this time, the armature 326 may include one or more second arc portion (3262) formed along the circumference of the other surface, the second roller 325 is located between the second arc portion (3262), the armature 326 It is rotated by the rotation of). The second arc portion 3262 is preferably formed in half the number of the second rollers 325. For example, when the number of the second roller parts 325 is n, the second arc parts 3262 may be n / 2 (n ≧ 2) pieces.

In addition, the resistor module 324 according to an embodiment of the present invention, see Figure 6, the body 3321, the first extension portion (3243) extending from the body 3241, the first extension portion (3243) extending from The second extension part 3244 and a third extension part 3245 extending from the second extension part 3244 may be included.

The body 3241 may be formed as an elliptical cylinder in which a through hole 3322 is formed at a central portion thereof, and a rotation shaft 3222 of the power unit connecting portion 322 may be inserted into the through hole 3324. The first extension part 3243 is formed to extend vertically from the body 3241, and the second extension part 3244 may be vertically bent and extended from one end of the first extension part 3243 to both sides. The third extension part 3245 may extend vertically bent toward one side of the body 3321 at one end of each second extension part 3244. In this case, the first extension part 3243 to the third extension part 3245 may be integrally formed. In addition, since the first extension part 3243 to the third extension part 3245 or the third extension part 3245 are formed of a material having a restoring force, the third extension part 3245 is formed by the external force. It may be bent to the 3243 side. At this time, the second roller 325 is disposed to contact the third extension portion 3245. In more detail, as the armature 326 rotates, the second roller 325 is pushed and rotated by the second arc portion 3326, and the resistance module 324 is pushed and rotated by the second roller 325. do. At this time, the third extension part 3245 of the resistance module 324 in contact with the second roller 325 is bent toward the first extension part 3243 and engaged with the second roller 325 in the third internal housing 323. ) Will be attached and rotated. At this time, the rotational speed of the armature 326 may be slowed down by the force pushing the third extension part 3245 to change the relative rotational speeds of the power transmission cam 328 and the armature 326. And the rotation speed difference between the power transmission cam 328 and the armature 326 is generated, the roller 327 is attached to the outer housing 329, the outer housing by the roller 327 in close contact with the outer housing (329) 329 rotates with armature 326. That is, while the rotational force of the motor 301 is transmitted to the output unit 330 through the input unit 310 and the clutch unit 320, the clutch unit 320 is the output unit 330 by the external force user A freely impossible or constrained load state can be implemented.

On the other hand, when the roller 327 attached to the outer housing 329 is detached from the outer housing 329, the outer housing 329 is free to move by the external force that can be generated by the user. That is, the clutch unit 320 can be implemented in the freewheeling state in which the output unit 330 is free to move by the external force.

In summary, as shown in FIG. 6, when the second roller 325 rotates, the resistance module 324 in contact with the second roller 325 is also pushed and rotated as the second roller 325 rotates. . At this time, since the second circular arc portion 3262 is positioned on both sides of the second roller 325, the resistance module 324 in the traveling direction regardless of the rotation direction (forward rotation or reverse rotation) of the armature 326 is also used. Can be pushed and rotated.

To this end, the resistance module 324 according to an embodiment of the present invention is formed of a material having a restoring force, so that the rotation speed difference between the power transmission cam 328 and the armature 326 can be more effectively generated. That is, due to the difference in rotational speed between the power transmission cam 328 and the armature 326, the roller 327 is attached to the inner circumferential surface of the outer housing 329 and the first circular arc portion 3221 on the rotational side side, and the third extension. By placing the portion 3245 between the first extension portions 3243, it is possible to generate a difference in rotation speed between the power transmission cam 328 and the armature 326 regardless of the rotation direction (forward rotation or reverse rotation).

The power transmission cam 328 is connected to the power unit connecting portion 322 and is a cam (CAM) member that can rotate according to the rotational force transmitted from the power unit connecting portion 322, and can be located inside the armature 326. have. To this end, the power transmission cam 328 according to an embodiment of the present invention, as shown in Figure 6, the plate-shaped main body 3231 and the one surface of the main body 3231 is formed in the through hole 3284 in the longitudinal direction In the vertical direction may include a rotation center axis (3282), the outer circumferential surface of the main body 3231 may be formed with a roller contact surface (3283) for contact with one or more rollers 327 provided in plurality have.

As shown in FIG. 6, the armature 326 is formed of a disc having a through hole 3263 formed thereon, and at least one second arc portion 3326 is formed along one circumference thereof, and one along the circumference thereof. It may be provided in a structure in which the first circular arc portion 3221 is formed. At this time, one or more rollers 327 are disposed between the first arc portions 3331, and the rollers 327 are pushed and rotated as the power transmission cam 328 rotates, and the first arc portions 3331 are disposed. Armature 326 is also formed to be pushed together to rotate. The second circular arc part 3262 may be disposed with the second roller 325 on both sides, and the second roller 325 may be pushed and rotated as the armature 326 rotates.

6 and 7, the roller 327 may be provided in the form of a member that can be pushed and rotated in accordance with the rotation of the power transmission cam 328 as one or more plurality of cylindrical shape elastic members. Can be.

The outer housing 329 may include a third gear 3291 formed to be rotatable on one surface as described above, and through this, the output unit fastened to the third gear 3291 as the outer housing 329 rotates. 330 can also be provided in a form that can rotate together. In addition, the external housing 329 may also be rotated through the coupling structure of the third gear 3291 and the output unit 330 fastened to the grip module 20, which may be rotated according to the user's intention. In addition, the outer housing 329, an optional function that can be attached or detached to the outer housing 329 by changing the relative rotational speed of the armature 326 according to the frictional resistance of the resistance module 324. possible implementations, and the selective implementation of the free-wheeling (free Wheeling) state, the no-load (No load) condition or the load (load) condition of this, the grip module (20) fastened to the output unit 330 through it is possible.

Also through a resistor module 324 shown in Fig. 6 freewheeling (Free Wheeling) state, the no-load (No Load) for the switch to the condition or the load (Load) condition will be described in more detail below.

As described above, the free-wheeling (Free Wheeling) state does not occur in the resistance of the mechanical configuration, release physical fastening between the grip module 20 and power module 30 to allow for movement, such as a free rotation in accordance with user's will (Blocking), that is, the grip module 20 may be defined as a state in which it can move freely without mechanical resistance. This is because the armature 326 is physically completely detached from the outer housing 329 by the resistance module 324, so that the outer housing 329 is not constrained at all by the armature 326 and the power unit 300. Non-parallel movement in the first and second directions with respect to the wrist module 10 (free rotation by the user's intention by the physical engagement of the outer housing 329 and the amateur 326 is released and It can be implemented in a state capable of moving) can be implemented in a free wheeling ( Free Wheeling ) state that can be possible.

In the state where the armature 326 is physically detached from the external housing 329 by the resistance module 324, the power supply by the motor 301, that is, the rotational force by the power unit 300 is transmitted to the power transmission cam ( The roller 327 which is not subjected to the pushing torque by the power transmission cam 328 on the premise that the state is not supplied to the 328 (the state that the power transmitted to the grip unit 20 through the power unit 300 is not supplied). ) Does not fit tightly between the first arc portions 3221 of the armature 326 (keep loose), so that the outer housing 329 is not restricted by the armature 326 housed therein. , and allow the user to the movement such as rotating the grip module 20, according to the free doctor, this user's grip module 20, a motion that does not feel a separate pharmaceutical through freewheeling (free Wheeling) state Implementation of.

In this state, no load ( No Load ) state is a state in which power transmitted to the grip unit 20 through the power unit 300 is not supplied, but the grip module 20 is physically coupled between the power module 30 ( For example, a power module connected through the clutch unit 320 in a state in which a mechanical resistance according to the output unit 330 is coupled to the grip module 20 through the third gear 3291 is generated. 30) By the internal mechanical fastening configuration, a certain level of resistance implies a state that imposes restrictions on the movement of the grip rotation 20 according to the user's intention.

In contrast, the load (Load) condition, the power from the power unit 30 is being supplied, additional grip module 20 and a power module 30, a grip module with the physical configuration entered via the clutch unit 320 ( By transmitting the power (rotational power) generated by the power module 30 to be transmitted to 20, to give the grip module 20 a different rotation force than the user's intention, through which the grip module 20 by the user's free will It can be defined as a state that places a constraint on the movement. In other words, the load ( Load ) state to be pursued by the present invention is a grip module that rotates in a set direction through the configuration of the clutch unit 320 and the output unit 330 through the rotation force generated by the drive of the power module 30 ( 20) can be defined as a state that can control the operation of the user to the contrary, that is, to generate a stronger resistance than the No Load state to restrain the user's free movement.

In order to implement such a function, the output unit 330 according to an embodiment of the present invention is divided into a third shaft 331, a fourth gear 332, a fifth gear 333, and a sixth gear 334. The third shaft 331 may be coupled to the housing 350 to be disposed in parallel with the second shaft 321.

The fourth gear 332 is formed with a through hole into which the third shaft 331 is inserted, rotatably coupled to the third shaft 331, and meshed with the third gear 3291 to form the third gear 3291. Receive torque.

The fifth gear 333 protrudes downward from the lower surface of the fourth gear 332. Since the fifth gear 333 is connected to one surface of the fourth gear 332, the fourth gear 333 is rotated together as the fourth gear 332 rotates.

The rotation recognition unit 340 is a component for detecting the angle of the sixth gear 334, and is located in one region of the housing 350 and has a measuring shaft 341 for grasping the angle of the sixth gear at the center thereof. It is. The sixth gear 334 is formed with a through hole that can be coupled to the measurement shaft 341, is coupled to the measurement shaft 341, meshed with the fifth gear 333, and transferred from the fifth gear 333. The rotational force can be transmitted to the measurement axis 341.

According to the exemplary embodiment of the present invention, the sixth gear 334 is formed to extend vertically on one surface, and may further include an extension part 3331 protruding to the outside of the housing 350, and the extension part 3331 is It may be connected to the grip module 20.

The extension part 3331 may output the rotation force transmitted from the clutch unit 320 to the outside of the housing 350 or transmit the rotation of the grip module 20 to the rotation recognition unit 340. That is, the rotation recognition unit 340 may grasp the rotation angle of the grip module 20.

In addition, according to an embodiment of the present invention, in addition to the power module 30, the n-th power unit may be present, in this case, the configuration of the n-th power unit may be provided in the same way as the configuration of the power module 30.

9 is a view for explaining the state of the clutch unit 320 when the load switching of the interface device 1 according to the embodiment of the present invention, Figure 9 (a) is an external housing 329 when switching to the load state ), The armature 326, the power transmission cam 328 and the like shown in cross-sectional view, Figure 9 (b) is a state of the third internal housing 323, the resistance module 324, etc. when switching to the load state. Is shown in cross section.

At this time, the load state is rotated by the second gear 313 in which the power unit connecting portion 322 is engaged to the disc, the roller 327 is attached to the outer housing 329, the outer housing 329 is armature 326 The rotation can be performed together with) and can not be rotated by an external force.

When the second gear 313 is rotated, the rotational force of the second gear 313 is transmitted to the power transmission cam 328 through the rotation shaft 3322, so that the first rotation transmission unit 328 rotates, The power transmission cam 328 pushes and rotates the roller 327 which is in contact with the roller contact surface 3283. At this time, as the rollers 327 disposed between the first arc portions 3331 are pushed and rotated, the armature 326 on which the first arc portions 3331 are formed to be pushed by the rollers 327 is also rotated together. As the armature 326 rotates, the second roller 325 disposed between the second arc portions 3326 is also pushed and rotated, and the resistance module 324 located in front of the second roller 325 in the rotational direction also moves. Will rotate together. At this time, the third extension part 3245 of the resistance module 324 is bent toward the first extension part 3243 by the second roller 325 positioned in the rotational direction of the second arc part 3326 and the armature 326. The speed of rotation of the motor is reduced, and thus, the speed difference between the power transmission cam 328 and the armature 326 occurs. Due to the difference in rotation speed, the roller 327 is attached to the outer housing 329, and the outer housing 329 rotates together with the armature 326 by the roller 327 in close contact.

The no-load state is the same as the fastening structure and the state of the clutch unit 320 and the like in the above-described load state, but assumes no power, that is, no rotational force from the power module 30 through the power unit connecting portion 322.

FIG. 10 is a view for explaining a state of the clutch unit 320 when switching the freewheeling state of the interface device 1 according to an embodiment of the present invention, and FIG. 10 (a) illustrates the switching to the freewheeling state. The external housing 329, the armature 326, the power transmission cam 328 and the like shown in cross-sectional view, Figure 10 (b) is a third internal housing 323, the resistance module (when switching to the freewheeling state) 324) and the like are shown in cross section.

At this time, even if the outer housing 329 rotates, the rotational force of the outer housing 329 is not transmitted to the power transmission cam 328. That is, based on FIG. 10, the rotational direction of the second gear 313 is opposite to that of the second housing 313. When the second gear 313 rotates in the direction (hereinafter, reverse rotation), the rotational force of the second gear 313 is transmitted to the power transmission cam 328 so that the power transmission cam 328 reverses. In this case, the power transmission cam 328 may push the roller 327 which is in contact with the roller contact surface 3283 to reverse rotation. At this time, as the roller 327 disposed between the first arc portions 3331 is pushed in reverse direction, the armature 326 in which the first arc portions 3331 are formed by being pushed by the roller 327 is also rotated in reverse. .

Then, as the armature 326 rotates in reverse, the second roller 325 disposed between the second arc portions 3326 is also pushed to reverse rotation, and the resistance module 324 positioned in front of the second arc portion 3326 in the rotation direction. ) Is also reversed. At this time, the third extension portion 3245 of the resistance module 324 is bent toward the first extension portion 3243 and decelerates the rotational speed of the armature 326, thereby causing the power transmission cam 328 and the armature 326. Difference in rotation speed occurs.

Due to the rotation speed difference, the roller 327 in close contact with the outer housing 329 and the armature 326 is detached from the outer housing 329 and the armature 326.

Then, when the power transmission cam 328 is rotated by a space that is not attached to the roller 327, the roller 327 does not contact the power transmission cam 328 and the outer housing 329 and the armature 326 ), Even if the outer housing 329 rotates, the components of the other clutch unit 320 therein do not rotate according to the rotation of the outer housing 329. That is, the outer housing 329 may be in a freewheeling state that can be freely rotated.

7 is an exploded perspective view of another type of clutch unit 320 according to an embodiment of the present invention, Figure 7a is a plan view of the clutch unit 320, Figure 7b is a perspective view of the clincher unit 320.

As can be seen through Figure 7, the clutch unit 320 according to an embodiment of the present invention is a power unit connecting portion 322, the structure and function, see the above description based on Figure 6, the resistance module 324 ), An armature 326, a roller 327, a power transmission cam 328, and an outer housing 329.

As shown in FIG. 7, the resistance module 324 is attached to the lower surface of the armature 326 and rotated by a roller 327 which is rotated in accordance with the rotation of the power transmission cam 328. It serves to adjust the rotational speed of 326, thereby enabling the implementation of the freewheeling state of the interface device (1).

To this end, the resistance module 324 according to one embodiment of the present invention may be provided as a solenoid that serves as an electromagnet.

When the resistance module 324 is provided as a solenoid and the armature 326 provided on the top of the resistance module 324 is provided as a magnetic material, the power transmission cam 328 according to the strength of the voltage applied to the resistance module 324. It is possible to reduce the rotational speed of the armature 326 to be rotated according to the rotation of the through the frictional resistance.

With reference to Figure 7, freewheeling and further describes the classification and conversion to (Free Wheeling) state, the no-load (No Load) condition and the load (Load) condition.

In the freewheeling state, the armature 326 is physically detached from the outer housing 329 by the resistance module 324 so that the outer housing 329 includes the armature 326 and the power unit 300. Since it is not restrained by the 300 at all, the grip module 20 may be implemented to be non-parallel to the wrist module 10 in the first and second directions. In this case, the non-parallel movement refers to a state in which the grip module 20 can freely rotate and move by a user's intention by the state in which the physical housing of the external housing 329 and the armature 326 is released.

On the other hand, the load state is the power unit in a physical fastening state through the roller 327 is formed of one or more than one outer housing 329 and the armature 326 sandwiched between the arc portion formed on the upper surface of the armature 326, Through the power supply by the 300, means the state to limit the rotational force transmitted to the grip module 20 and the external housing 329 by the user, the no-load state, the external housing 329 and the amateur While 326 is physically fastened by the roller 327 sandwiched between the arc portions of the armature 326, the power supply is interrupted by the power unit 300, but through the grip module 20 by the user and through The rotational force transmitted to the external housing 329 is the user's grip module 20 by the physical coupling structure of the power module 30 and the grip module 20, that is, the mechanical resistance through the clutch unit 320 and the output unit 330. Nothing to constrain the movement This optional implementation is possible with the load state.

In the absence of rotational power supply through the power unit 300 in order to implement such a differentiated state, when a voltage higher than the level set in the resistance module 324 is applied ( referred to as "threshold value" ), the armature 326 is physically present. By completely falling out of the outer housing 329, the movement of the free rotation and the front and rear, left and right movements in the state that is not restrained by the armature 326 and the power module 30 connected thereto is accommodated therein Possible freewheeling state implementations are possible.

On the other hand, when the power transmission cam 328 rotates according to the power supply by the power unit 300, the roller rotation of the roller 327 according to the rotation of the power transmission cam 328, the rotation of the armature 326 accordingly And, sandwiched between the arc of the armature 326 (a kind of wedge action ), the armature 326 and the outer housing 329 are mutually coupled, through which the outer housing 329 also rotates to move the grip module 20. In addition, it is possible to implement a load state that controls the rotation. In this case, in order to maximize the efficiency of the power unit 30, it is preferable not to apply a separate power source to the resistance module 324 so that additional frictional resistance does not occur in the armature 326.

On the other hand, in a state in which there is no power supply by the power unit 300, that is, in a state in which there is no rotational drive of the power transmission cam 328, the power supply of a threshold value or less is applied to the resistance module 324 or not. The magnetic armature 326 provides frictional resistance in rotation, and generates a difference in rotational speed within various ranges of the outer housing 329 and the armature 326, but still has an outer housing 329 and a power module. By allowing the 30 to be fastened, it is also possible to implement a non-load state capable of transmitting a certain physical and mechanical constraints and resistance to rotation of the user's grip module 20. In particular, by varying the value of the power supply below the threshold value applied to the resistance module 324 to provide a variety of rotational speed difference or fastening coupling strength between the outer housing 329 and the armature 326, the user 1 ) It can have a feature to enjoy various feedback (Force Feedback) according to the use.

That is, provided by the resistance module 324 located on the lower surface of the armature 326 connected through the drainage structure of the protrusion 327 to the outer housing 329 to be rotated together as the user rotates the grip module 20. According to the magnitude of the frictional resistance, the armature 326 restricts the rotation of the armature 326 which is subjected to the frictional resistance to the rotation ( that is, the frictional resistance value according to the voltage strength below the threshold applied to the resistance module 324). Change and consequent limitation of the rotatable speed ), thereby allowing the rotation or movement of the outer housing 329 connected through the armature 326 and the protrusion 328 to be restricted within a certain range.

In addition, the clutch unit 320 according to an embodiment of the present invention is a physical coupling (A) of the power unit 300 and the grip module 20 through the resistance module 324, more precisely, the outer housing 329 and the armature. Adjusting the formation or release of the physical fastening through the protrusion 327 of the 326, the power module 30 is transmitted to the grip module 20 through the power unit 300, more specifically the output unit 330 ) Through the coupling configuration of the third gear 3291, and to control the generation or disappearance of the rotational force (B) can be, the formation and release of the physical coupling (A) through the resistance module 324 and the power module (30) Interface device (1) characterized in that the grip module 20 can selectively implement any one of a no-load state, a load state or a freewheeling state by selectively combining the generation and the dissipation of the rotational force B through ) Can be implemented.

Such freewheeling interface device according to the request or an embodiment of the present invention of (Free Wheeling) state, the no-load (No Load) condition and the load (Load) condition is the external device 3 are connected via a network, as described above ( 1) can be adjusted according to the situation that is recognized through the control unit 60 or the rotation recognition unit 340, that is, the movement state of the grip module 20, the rotation state or the user's needs, through which the immersion of the user There is an advantage that can be further enhanced.

In addition, the clutch unit 320 according to an embodiment of the present invention, as shown in Figure 8, may be adopted an elastic member such as a spring as a form of the resistance module 324. Similar to the clutch unit 320 according to another embodiment described above, the resistance module 324 according to FIG. 8 provides frictional resistance to rotation of the armature 326 to generate a difference in rotational speed with the external housing 329. It will play a role.

As shown in the upper two images of FIG. In case of switching, the hexagonal power transmission cam and the round roller are separated from each other. In the lower two images of FIG. 11, the roller is attached to the hexagonal power transmission cam when the no load or load state is switched. It shows the state that there is.
