The base frame 110 may be mounted on a support such as a wall or reference plane 1. The rotating frame 120 is rotatably coupled to the base frame 110. In the coupling of the base frame 110 and the rotation frame 120, the pivot shaft 191 is coupled to the base frame 110, as shown in Figure 1, the pivot rod 190 is pivot axis 191 The bearing is coupled to and rotatably connected to rotate about the base frame 110 about the pivot shaft 191. At this time, the rotation frame 120 may be coupled to the end of the pivot rod 190, the rotation frame 120 is rotated in accordance with the rotation of the pivot rod 190.

On the contrary, the present invention does not include the base frame 110 and rotates as the rotating frame 120 and the rotating frame 120 that can be rotated forward or reverse in the first direction with respect to a support such as the reference plane 1.

In addition, the embodiment of the present invention shown in Figs. 2 to 4 may be arranged on the reference plane 1 by changing the upper and lower sides with respect to the ground to change the rotation angle and the rotation direction.

The slide frame 130 is connected to slide with respect to the rotating frame 120. The base bracket 140 is disposed on the slide frame 130 to move together with the slide frame 130 as the slide frame 130 slides with respect to the rotating frame 120. The panel mounting bracket 150 is pivotally coupled to the base bracket 140 so as to be rotatable, and the panel mounting bracket 150 is equipped with a display device.

The first driving assembly 160 is connected to the motor 180 to rotate the rotating frame 120 with respect to the base frame 110. The second driving assembly 170 is connected to the motor 180 to move the slide frame 130 so that the slide frame 130 slides with respect to the rotation frame 120.

The motor 180 is disposed in the rotating frame 120.

As the motor 180 is driven, as shown in FIG. 2, the rotation frame 120 is positioned at the first rotation frame 120 ′ in the direction S perpendicular to the reference plane 1. Rotates about the pivot axis 191 of the base frame 110 to the position "." As the rotating frame 120 rotates, the slide frame 130 is first rotated relative to the left and right direction D rotating frame 120. The slide frame 130 ′ may move from the position of the second slide frame 130 ″.

The principle of rotation of the rotation frame 120 relative to the base frame 110 and the movement principle of the slide frame 130 relative to the rotation frame 120 according to the driving of the motor 180 will be described with reference to FIG. 5. 5 illustrates a structure for transmitting rotational force as the motor 180 is driven according to the present embodiment. As the motor 180 is driven, the structure for transmitting the rotational force may be configured by the first driving assembly 160 and the second driving assembly 170.

As shown in FIG. 5, the first drive assembly 160 may include a shaft 182 connected to the motor 180 to transmit rotational motion and a pivot shaft 191 connected to the base frame 110. Can be.

Here, FIG. 5 includes the first safety device 200, but in order to describe the present embodiment, the present embodiment does not include the first safety device 200 and is described under the assumption that the pivot shaft 191 is fixed. Do it. An embodiment including the first safety device 200 will be described later.

When the shaft 182 connected to the motor 180 is rotated by the rotation of the motor 180, the rotation of the shaft 182 rotates the first cross gear 183 positioned at one end of the shaft 182. Here, the first cross gear 183 is in contact with the first fixed gear 192, where the first fixed gear 192 is disposed at one end of the pivot shaft 191 and the other end of the pivot shaft 191 is a base frame ( 110). Since the other end of the pivot shaft 191 is fixed, the first fixed gear 192 disposed at one end of the pivot shaft 191 is also fixed. Here, when the first cross gear 183 engaged with the first fixed gear 192 is rotated by the rotation of the motor 180, the first cross gear 183 is an axis of the first fixed gear 192, namely, It rotates about the pivot axis 191 in the direction perpendicular to the axial direction of the 1st fixed gear 192. FIG. A shaft 182 connected to the first cross gear 183 when the first cross gear 183 rotates about an axis of the first fixed gear 192; A motor 180 connected with the shaft 182; And a rotating frame 120 to which the motor 180 is attached rotates about the pivot shaft 191, and the pivot rod 190 connected to the rotating frame 120 is bearing-coupled with the pivot shaft 191 to rotate. Rotate together with frame 120.

Here, the shaft 182 and the pivot shaft 191 may be connected by a combination of various gears. For example, as shown in FIG. 5, the shaft 182 and the pivot shaft 191 may be connected to a bevel gear or a worm gear. Coupling of the gear is not limited to this and those skilled in the art will appreciate that a variety of gear coupling is possible. In this case, the worm gear has less backlash than the bevel gear, and thus can efficiently transfer energy.

On the other hand, the other end of the pivot shaft 191 is not fixed to the base frame 110, it is connected to the first safety device 200 as shown in Figure 5 and the first safety device 200 is the base frame 110 Can be fixed). In this case, the first safety device 200 may be configured to rotate by idling with the shaft 182 when a predetermined or more rotational force is transmitted to the pivot shaft 191.

If a predetermined or more rotational force is transmitted to the pivot shaft 191, if the shaft 182 does not idle, it may cause a safety problem and may cause injury to the human life. In addition, the motor 180 may be overloaded to damage the motor 180. I can wear it. That is, when the rotation frame 120 is rotated by the operation of the motor 180, an obstacle such as a user prevents the rotation of the rotation frame 120, and the rotation frame 120 is rotated by the motor 180. If you continue to proceed in the first direction, it may be a safety problem for the user. In addition, if the obstacle that interferes more than the rotational force of the motor 180 acts so that the motor 180 can not rotate, the motor 180 may be overloaded.

6 is a schematic side view of the first safety device 200 according to the present embodiment. One side of the first safety device 200 may be connected to the pivot shaft 191 and the other side may be fixed to the base frame 110.

The first safety device 200 may be configured not to rotate until a predetermined rotational force occurs on the pivot shaft 191. If the rotation frame 120 is supported by the obstacle to stop the rotation, the rotational force transmitted to the pivot shaft 191 by the continuous rotation of the motor 180 is increased. As such, when a force equal to or greater than a predetermined rotational force is applied to the pivot shaft 191, the pivot shaft 191 idles with the shaft 182 to protect the safety of the user and also protect the motor 180 from overload.

For example, a method of rotating the pivot shaft 191 together with the shaft 182 is as follows. In FIG. 5, the first safety device 200 may be disposed to be connected to the pivot shaft 191, but as illustrated in FIG. 6, the pivot shaft 191 may be coupled to the first coupling 202. The pivot shaft 191 and the first coupling 202 are axially connected to the first friction plate 203 so as to be rotatable. At this time, the first coupling 202 is fixed to the first friction plate 203 by a friction force between one end of the first coupling 202 and the first friction adjusting nut 205. The first dish spring washer 204 may be disposed on the axis of the first coupling 202 between the first friction adjusting nut 205 and the first friction plate 203. The first dish spring washer 204 is rotatably connected to the first friction plate 203 and is supported by the friction force. At this time, the first friction plate 203 is fixed to the base frame 110. Therefore, in FIG. 5, as the shaft 182 rotates, the pivot shaft 191 also receives a rotational force to rotate, but the pivot shaft 191 is driven by the frictional force between the first dish spring washer 204 and the first friction plate 203. Does not rotate Instead, the shaft 182 is rotated about the fixed pivot shaft 191. If the shaft 182 is stopped by an obstacle, the shaft 182 does not rotate about the pivot shaft 191, so that the rotational force of the shaft 182 is transmitted to the pivot shaft 191. At this time, when the rotational force transmitted to the pivot shaft 191 is greater than the friction force between the first dish spring washer 204 and the first friction plate 203, the first dish spring washer 204 and the pivot shaft 191 is idling.

On the other hand, the scope of protection of the present invention is not limited to this, an example that can be easily changed by those skilled in the art from the idling method of the pivot axis 191 described herein will be said to belong to the scope of protection of the present invention.

Here, the first safety device 200 is fastened to the outside of the first coupling 202 and the first coupling 202 coupled to the pivot shaft 191, as shown in Figure 6 of the frictional pressure A first dish positioned outside the first friction adjusting nut 205, the first coupling 202, and the first friction adjusting nut 205 for adjusting the force to provide friction pressure to the first friction plate 203. On the left and right sides of the spring washer 204, the first friction plate 203 and the first friction plate 203, first felt material 206 such as leather is disposed, and the first friction plate 203 is disposed. The 1st flat washer 207 can be arrange | positioned at the left and right sides of the 1st felt material 206, and can be comprised. The first friction plate 203 may be fixedly coupled by the first fixed coupling device 201, and the first fixed coupling device 201 may be fixed to the base frame 110.

The first safety device 200 is not limited thereto, and may be variously configured, and those skilled in the art may change the first safety device 200 to other members in the same manner in configuring the first safety device 200. It will be appreciated that 200 may be configured.

In addition, FIG. 5 illustrates a second drive in which the slide frame 130 slides longitudinally with respect to the rotation frame 120 as the second cross gear 181 on the shaft 182 is rotated as the motor 180 is driven. The assembly 170 is shown.

The second drive assembly 170 may be configured through a combination of various gears.

FIG. 7 shows a cross-sectional view taken along line II of FIG. 1. An embodiment of the second drive assembly 170 will be described with reference to FIGS. 5 and 7. As shown in FIG. 5, the second intersecting gear 181 on the shaft 182 may rotate as the shaft 182 connected to the motor 180 rotates. In addition, the first rotary gear 241 connected to the second cross gear 181 rotates through the rotation of the second cross gear 181. Coupling of the shaft 182 and the first rotary gear 241 may be configured as a worm gear coupling or bevel gear coupling. In this case, the worm gear has less backlash than the bevel gear, and thus can efficiently transfer energy.

According to FIG. 7, when the first rotary gear 241 rotates, the second rotary gear 245 connected in the same axis rotates, and the second rotary gear 245 according to the rotation of the second rotary gear 245. The third rotary gear 242 is in contact with the rotation, and the fourth rotary gear 243 axially coupled with the third rotary gear 242 through the rotation of the third rotary gear 242 rotates. In this case, the fourth rotary gear 243 may be configured as a spur gear. The rotation of the fourth rotary gear 243 may be in contact with the first linear gear 244 to convert the rotary motion into a linear motion. Here, the first linear gear 244 may be composed of a rack gear.

FIG. 8 is a schematic front view of the embodiment of the present invention of FIG. 1 viewed from the other side of the rotating frame 120. According to FIG. 8, in the second drive assembly 170, through the fourth rotary gear 243 and the first linear gear 244, the first linear gear 244 according to the rotation direction of the fourth rotary gear 243. The slide frame 130 which is bite may slide in the left and right directions (D).

In addition, in FIG. 5, the second driving assembly 170 may include a second safety device 250. The second safety device 250 is shown in FIG. 9. The operation of the second safety device 250 will be described with reference to FIG. 9. In FIG. 8, when the slide frame 130 is stopped by an obstacle while sliding, the first linear gear 244 connected to the slide frame 130 is stopped. When the first linear gear 244 is stopped, the gears are sequentially stopped and the first rotary gear 241 is stopped. In FIG. 9, if the first rotating gear 241 is stopped by an obstacle such as a person and the motor 180 continues to operate, safety problems may occur due to the movement of the slide frame 130. In addition, if the first rotary gear 241 is fixed despite the rotation of the motor 180, the motor 180 may be overloaded and may be damaged. Accordingly, in the second safety device 250, the second rotary gear 245 stops and the first rotary gear 241 rotates so that a predetermined or more torque difference is between the first rotary gear 241 and the second rotary gear 245. When it occurs, the second rotary gear 245 is fixed and the first rotary gear 241 can be configured to rotate. Those skilled in the art will be able to configure this in various ways. For example, as shown in FIG. 9, the second coupling 252 may be coupled with the second rotary gear 245. The second coupling 252 is coupled to the second dish spring washer 254. At this time, the second dish spring washer 254 is rotatable to the second friction plate 253 is connected to be supported by the friction force. At this time, the second friction plate 253 is coupled to the first rotary gear 241.

Here, the second plate spring washer that is supported by the friction force on the second friction plate 253 as the second friction plate 253 rotates as the first rotary gear 241 rotates, and the second friction plate 253 rotates. 254 rotates. Rotation of the second dish spring washer 254 rotates the second rotary gear 245 by the second coupling 252. If the second rotary gear 245 is fixed by an obstacle or the like and the first rotary gear 241 continues to rotate, the difference in the rotational force applied to the first rotary gear 241 and the second rotary gear 245 is the second dish. When greater than the frictional force on the spring washer 254 and the second friction plate 253, the second friction plate 253 rotates relative to the second dish spring washer 254, the first rotary gear 241 is shown in FIG. It may be idling with shaft 182 at five.

As such, the second safety device 250 may be configured similarly to the first safety device 200. In FIG. 9, a second friction adjusting nut 255 may be disposed outside the second coupling 252 to adjust the force of the frictional pressure. That is, the friction force is generated between the second counter-spring washer 254 and the second friction plate 253 by the pressure between one end of the second coupling 252 and the second friction adjusting nut 255, so that the second friction plate 253 The rotation causes the second dish spring washer 254 to also rotate.

At this time, the second rotation gear 245 connected to the second coupling 252 is stopped and the rotational force to continue to rotate the second friction plate 253 connected to the first rotation gear 241 is the second friction control nut 255 When the frictional force between the second dish spring washer 254 and the second friction plate 253 is greater than), the second friction plate 253 idles with the first rotation gear 241. In addition, a second felt material 256 such as leather may be disposed on the left and right sides of the second friction plate 253. In addition, the second flat washer 257 may be disposed on the left and right sides of the second felt material 256 disposed on the second friction plate 253. Here, the second friction plate 253 may be coupled to the first rotary gear 241.

The second safety device 250 is not limited thereto, and may be configured in various ways, and those skilled in the art may change the second safety device (e.g., replace other members with other members in the configuration of the second safety device 250). It will be appreciated.

In FIG. 5, FIG. 7 or FIG. 8, the second driving assembly which transmits rotational force as the motor 180 is driven together with the first safety device 200 and the second safety device 250 according to an embodiment of the present invention. One embodiment of 170 is shown. Embodiment of the second drive assembly 170 is not limited thereto. For example, referring to FIGS. 10 to 12, another embodiment of the second drive assembly 170 will be described.

As shown in FIG. 10, the motor 180 is axially coupled with the second cross gear 181, and the second cross gear 181 is axially coupled with the fifth rotary gear 186. When the second cross gear 181 rotates by the driving of the motor 180, the first rotation gear 241 connected with the second cross gear 181 rotates, and at the same time, the second cross gear 181 rotates. And the fifth rotary gear 186, which is axially coupled with the rotating shaft, rotates the sixth rotary gear 187 connected with the fifth rotary gear 186, and the rotation of the sixth rotary gear 187 is performed by the shaft 182. ) And the rotation of the shaft 182 is transmitted to the first drive assembly (160). In addition, referring to FIG. 11, the first rotary gear 241 may be connected to the second safety device 250, and the other side of the second safety device 250 may be connected to the fourth rotary gear 243. The rotation of the fourth rotary gear 243 may be in contact with the first linear gear 244 to convert the rotary motion into a linear motion. Rotation of the fourth rotary gear 243 disposed on the other side of the rotary frame 120 is connected to the first linear gear 244 to move the slide frame 130. Here, the first linear gear 244 may be composed of a rack gear.

Here, the coupling of the second cross gear 181 and the first rotary gear 241 may be configured as a worm gear coupling or bevel gear coupling. In this case, the worm gear has less backlash than the bevel gear, so it can efficiently transfer energy.

At this time, the connection between the second drive assembly 170 and the second safety device 250 of the present embodiment will be described with reference to FIG. 9 without a separate drawing. In FIG. 12, the first rotary gear 241 is coupled to the second friction plate 253 of the second safety device 250 shown in FIG. 9, and the fourth rotary gear 243 is the second coupling ( 252) may be configured. Therefore, when the first linear gear 244 is stopped by an obstacle or the like, the fourth rotary gear 243 connected to the first linear gear 244 is stopped and thus the fourth rotary gear 243 and the first rotary gear ( If the difference in the rotational forces acting between the 241 exceeds the predetermined frictional force in the second safety device 250, the fourth rotary gear 243 is stopped and the first rotary gear 241 is the second cross gear 181 Can be idle with

The driver 430 drives the motor 180 in response to the control value output from the controller 420.

In the control system 400, for example, the receiver 410 may be configured as the sensor 300, the first switch 310, and the second switch 320 as shown in FIG. 18, but is not limited thereto. It will be appreciated that various embodiments are possible.

The sensor 300 may measure the rotation angle of the rotation frame 120 with respect to the reference plane 1 of the base frame 110 by the number of revolutions of a rotor (not shown) in the sensor 300. For example, rotation allowing each of the rotating frame 120 with respect to the base frame 110 is ⁹⁰ when, since the rotating frame 120 is arranged to the rotor by one rotation in a 10 ^rotating the sensor 300, the rotor The position of the rotation frame 120 with respect to the reference plane 1 of the base frame 110 can be recognized by the number of revolutions. For example, the rotor 4 when the rotation means rotates the frame 120 with respect to the reference plane (1) of the base frame 110 rotates ⁴⁰ state.

The first switch 310 may be disposed on one surface of the rotating frame 120 as shown in FIG. When the rotating frame 120 is as close as possible to the reference plane 1 in the initial state, the first switch 310 is turned on under pressure from the first switch corresponding point 311, which is a point on the base frame 110. If the rotation frame 120 moves in a direction S ₂ away from the reference plane 1 about the pivot shaft 191, the first switch 310 is turned off from the first switch corresponding point 311 to be in an off state. . Therefore, since the first switch 310 is in an On or Off state, the position of the rotation frame 120 may be recognized with respect to the reference plane 1 of the base frame 110.

The second switch 320 may be disposed between the other surface of the rotating frame 120 and the slide frame 130. In the initial state, the slide frame 130 is positioned in a direction D ₁ close to the base frame 110 with respect to the rotating frame 120, so that the second switch 320 is kept on by the slide frame 130. Done. When the slide frame 130 moves in a direction D ₂ away from the base frame 110 as the rotating frame 120 rotates, the second switch 320 is in an off state. As described above, since the second switch 320 is turned on or off, the position change of the slide frame 130 with respect to the rotation frame 120 may be recognized.

20 illustrates one embodiment of a flow chart for controlling the position of the rotating frame 120 and the slide frame 130 through the control system 400.

According to FIG. 20, the control system 400 maintains the command standby mode S501 before receiving the command value. When the input command (S502), first determines whether the command value of the rotation ^{90. (S503).} Wherein a command value for rotating the rotation frame 120 in the direction (S ₂₎ away from the plane (1) from ⁹⁰ rotation is 18.

If the command value is rotation ^90. The motor starts (S504) the operation in the positive rotation direction. It is determined whether the first switch 310 is On or Off while driving in the forward rotation direction of the motor (S505). If the first switch 310 is On, the rotating frame 120 is still far from the reference plane 1. Recognizing that it has not been maintained and maintains the forward rotation of the motor (S504).

After determining the on / off of the first switch 310, it is also determined the on / off of the second switch 320 (S506). When the first switch 310 and the second switch 320 is Off, the rotation frame 120 and the slide frame 130 is moving, so the control system 400 rotates the rotor (not shown) of the sensor 300. The number is determined (S507). In this case, the sensor 300 may have a maximum rotational speed and a minimum rotational speed as a predetermined limit value with respect to the rotatable angle of the rotation frame 120. For example, a rotation frame 120 is ^110. Rotatable a substantially rotation frame 120. When when rotating with respect to the reference plane (1) of the base frame 110 to rotate at ²⁰ up to ^90. Here the have. At this time, when the rotor is rotated 1 rotation every time the rotation frame 120 rotates 10 ^. Practically up to 11 turns. Therefore, the sensor 300 recognizes the rotation speed and determines a case where the rotation speed is equal to or greater than the maximum rotation speed (S507). If the rotation speed is equal to or greater than the maximum rotation speed, the motor stops driving (S509) and returns to the command standby mode (S501).

When the sensor 300 measures the rotation speed, the rotation frame 120 may be caught by an obstacle or the like to prevent movement. In this case, the sensor 300 calculates a delay time for which the rotation speed does not increase any more at a predetermined rotation speed or a time for reaching the maximum rotation speed after the initial motor forward rotation driving so that the delay time is a predetermined delay value. If longer, the motor may be rotated in reverse (S551). That is, in FIG. 18, when the rotation frame 120 encounters an obstacle when moving in the direction S ₂ away from the reference plane 1, the control system 400 moves in the direction S in which the rotation frame 120 approaches the reference plane 1. Can be moved to ₁ ).

Receives the command (S502), first command value is ^90. Rotation whether the determination (S503) in the step of, the command value ^90. The ^non-zero in the case (S550) a reverse rotation driven (S551) rotating frame motor ( 120 moves in a direction S ₁ close to the reference plane 1.

When the motor is driven in reverse rotation, it is determined when the first switch 310 reaches the first switch corresponding point 311 of the base frame 110 to be turned on (S552). When the first switch 310 is turned on, It is determined whether the second switch is turned on (S553). When the second switch 320 is also turned on, the sensor 300 determines whether the number of revolutions of the rotor is equal to or smaller than the minimum number of revolutions (S554). When the rotation speed of the rotor is equal to or smaller than the minimum rotation speed, the motor stops driving (S556) and returns to the command standby mode (S501).

In comparing the rotation speed of the rotor in the sensor 300, the rotation frame 120 may be caught by an obstacle or the like to prevent movement. In this case, the sensor 300 calculates the delay time of the delay time that the rotation speed does not increase any more at a predetermined rotation speed or the time to reach the minimum rotation speed after the initial motor reverse rotation driving so that the delay time is a predetermined delay value. If longer, the motor can be rotated forward (S504). That is, in FIG. 18, when the rotation frame 120 encounters an obstacle when moving in the direction S ₁ away from the reference plane 1, the control system 400 moves in a direction S in which the rotation frame 120 approaches the reference plane 1. ₂ ) can be moved.

Receives the command (S502), first command value is ^90. Rotation if the determination in (S503) step that, when the command value is not also not ^zero is ^90. (S550) The motor stops driving (S557) and a command Return to the standby mode (S501).

One embodiment of the control system 400 is not limited thereto and those skilled in the art will recognize that various embodiments are possible. For example, when the rotation frame 120 encounters an obstacle during the rotation, the control system 400 may stop the rotation of the motor to stop the rotation of the rotation frame 120.
