1 is a view showing a wall-shaped frame of the smart wall 100. The present invention relates to a smart wall 100 in which electronic devices used at home, such as media devices and home appliances, are integrated on a wall so that they are not exposed to the exterior. Various electronic devices such as display unit, interphone, speaker, air purifier, humidifier, lighting, digital clock, router, and set-top box are mounted on the wall to provide a total space solution that minimizes the exposure of electronic devices in the space.

Recently, as the thickness of the display device 161 has become thinner, the thickness of the smart wall 100 can be formed to be as thin as 15 to 20 cm, so that the indoor space can be prevented from being narrowed during installation. Rather, storage furniture and home appliances 160 may be embedded in the smart wall 100 to provide a neat appearance. If necessary, a part of the wall may be selectively drawn out so that the necessary home appliance may protrude, and the space where the home appliance is not buried may be utilized as a mounting space 114 such as a drawer.

A TV can be made thinner in recent years, and thus a thin display unit can be implemented. In reality, the TV itself serves as a cover for the frame and can be combined with the frame to form a front appearance. An opening 153 may be formed in the art wall 151 to expose the display portion of the display device 161, and a cover for opening and closing the opening 153 may be further provided.

Since the display unit using OLED is bent, it is exposed to the outside only when in use, and when not in use, it can be rolled up and stored inside the wall, thus providing a neat screen in appearance.

As for the projector, a short throw projector was recently developed, and a large screen can be realized by mounting the projector on a wall, drawing it out in a drawer format, and outputting it to the screen. In this case, when not in use, the display unit is not visible on the outside of the smart wall 100 so that a cleaner appearance can be provided.

2 is an exploded view of the smart wall 100, the interior of the front art wall 150 may be a structure of a frame in which a plurality of shape steel 115 (shape steel) is arranged in a grid. The frame structure 110 is a rigid member and can be supported so as not to collapse even when an impact is applied to the wall. A panel may be attached to the front of the frame structure 110 to hide the electronic product 160 mounted on the frame structure 110 and be configured to appear as a wall. The front wall covered with such a panel is referred to as an art wall 150.

The art wall 150 can be changed differently according to a consumer's taste. After installation, you can easily change it to change the atmosphere of your home.

The section steel 115 arranged in a grid form may partition the mounting space 114 and mount the electronic product 160 in each mounting space 114. Each of the mounting spaces 114 may have the same size or multiple sizes, so that the mounted electronic product 160 may be modularized and disposed at any position in the frame structure 110.

In addition to the above-described display device 161, a sound device 152 such as a speaker 162 may be mounted in the mounting space 114, and a plurality of sound devices 152 may be configured according to the number of channels. The art wall 152 covering the sound device may be configured in a mesh shape so that sound can be output, or an opening that is exposed to the outside may be minimized by selectively opening and closing an opening through which sound is output. For waterproofing, the opening may be prevented from inflow of water by using a waterproof mesh or the like.

Seasonal appliances such as a dehumidifier 163, a humidifier 165, an air conditioner, and a stove may be provided. Such seasonal home appliances are generally exposed to the outside when they are not in use, and dust accumulates and looks bad, so it is common to put a cover on it or put it in a warehouse. However, if it is embedded and installed in the smart wall 100 as in the present invention, it can be used when necessary, and when not used, it can be covered with the art wall 150 so that it is not exposed to the outside, and a separate mounting space 114 is provided. no need.

The dehumidifier 163 or the humidifier 165 may implement a drawer-type space for collecting/storing water to remove collected water or fill water. An opening 154 through which air passes in order to discharge water or collect moisture around it is required. The air purifier can be installed on the lower part of the smart wall 100 so that the user can easily open the filter so that the filter can be replaced periodically.

Even if these openings 154 are not necessarily formed in the art wall 150, the gap between the art wall 150 and the frame structure 110 may be used.

In addition, if a set-top box or WIFI router is installed, it can be implemented as a home network system. Through the WIFI router, not only the functional units mounted on the smart wall 100 but also other electronic devices such as a computer or a portable terminal located outside the smart wall 100 can be connected and controlled by interworking with each other.

An LED or a small display panel can be arranged on the top to provide simple information such as weather and time event information to the user, or can be used as lighting. By arranging lighting on the smart wall 100 itself, it is possible to add an interior effect.

A router is an intermediate device that, when using different communication methods or signals, organizes and guides the router. In addition, the functional unit mounted on the smart wall 100 may not necessarily be connected by wire, but may be connected and controlled through a WIFI router.

In addition, since the router plays a role of connecting the external network and the internal network at the same time, the user controls the router connected to the external network from the outside to control not only the functional units mounted on the smart wall 100 but also home appliances and media devices connected to the internal network. can do

In addition, electronic devices of the smart wall 100 may be controlled by interlocking with a mobile device. That is, when a mobile device is mounted on the smart wall 100, media images and music in the mobile device are output, or when a video call is received through the mobile device, the other party's image can be provided through the display of the smart wall 100. have.

In addition, a wall pad connected to a camera or method system at the entrance may be provided in the mounting space 114 of the smart wall 100. Wall pads that were buried in the existing bearing wall were difficult to repair and replace in case of failure, and difficult to change their location. However, if the wall pad is configured in a unit form and provided in the smart wall 100, there is an advantage in that maintenance is easy.

The smart wall 100 can be installed not only in the living room but also in the room. By configuring the walls between the rooms as the smart wall 100, the smart wall 100 may be used in both directions in neighboring rooms. For example, if one air conditioner or air purifier is passed in both directions, it can be used in both spaces. Instead of the TV and speaker 162 used in the living room, a monitor and a PC may be mounted and used according to the purpose of the room. Alternatively, other functional units such as an electronic blackboard may be mounted and used according to the child's age.

When installed in an office, a smart wall 100 equipped with a functional unit such as an electronic blackboard, an air purifier, a video conference system, and a PC can be used. Since the electronic product 160 mounted on the smart wall 100 is covered by the art wall 150, a separate exterior case is not required.

If the smart wall 100 is manufactured according to the user's installation location at the factory and then installed, the same module can be manufactured and supplied on a large scale when constructing a hotel/resort or apartment, reducing the defect rate and producing it at low cost.

However, the assembled smart wall 100 is difficult to transport, and when the building is completed, it is difficult to carry it into the building. Accordingly, when the smart wall 100 is installed when moving or interior in an existing building, the smart wall 100 may be implemented by installing a frame in the building and inserting a unit module. In this case, for convenience and standardization of installation, the frame structure 110 may be implemented using a plurality of module frames.

3 illustrates a method of combining frame modules 111, 112, and 113 of the smart wall 100 according to an embodiment. In order to mount each component, frame modules 111, 112, and 113 in the form of a bookshelf including a mounting space 114 may be used. Frame modules 111, 112, and 113 may be manufactured by arranging a plurality of beam-shaped members in a grid to partition the mounting space 114.

The frame modules 111, 112, 113 are a first frame module 111 in which the mounting spaces 114 are arranged side by side in a horizontal direction, and a second frame module for mounting a large product 160 such as a display device 161 It may include a third frame module 113 in which 112 and the mounting space 114 are arranged side by side in the vertical direction.

The second frame module 112 includes a large space so that all of the display devices 161 can be mounted regardless of the inch. If necessary, as shown in FIG. 4, the display device 161 may be fixed by providing a beam that partitions the mounting space 114 and the rigidity of the frame structure 110 may be improved.

The first frame module 111 may be stacked and disposed in a vertical direction with the second frame module 112. The length of the first frame module 111 in the horizontal direction may be the same as the length of the second frame module 112 in the horizontal direction, so that the grid may not be displaced when stacked in the vertical direction.

The first frame module 111 may be disposed on the upper side and the lower side of the second frame module 112, respectively, and according to the size of the first frame module 111 and the second frame module 112 or the size of the installation space. Accordingly, the number of stacked first frame modules 111 in the vertical direction may be increased or decreased.

The third frame module 113 in which the mounting spaces 114 are arranged in the vertical direction may have the same height as the first frame module 111 and the second frame module 112 stacked in the vertical direction. The third frame module 113 may be located in the lateral direction of the first frame module 111 and the second frame module 112 as shown in FIG. 4. A plurality of frame modules 111, 112, 113 may be combined with fasteners to form a rectangular parallelepiped frame structure 110.

4 is a diagram illustrating a method of manufacturing the frame modules 111, 112, and 113, and a third frame module 113 in which the mounting space 114 is disposed in a vertical direction will be described as an example. Each of the frame modules 111, 112, and 113 may use a section steel 115 that is elongated in one direction. Shape steel is a structural member and collectively refers to a rod-shaped member having various cross-sectional shapes. It is possible to construct a column-shaped section steel having the same cross-section in the longitudinal direction by rolling or bending the plate. Section steel has an advantage of being able to obtain rigidity of a certain size or more with lighter and less material since there is an empty space than a beam-shaped member having a circular or square cross section.

The present invention may use a C-beam 115 having a C-shaped cross section as shown in FIG. 4. The C-beam 115 may be formed by vertically bending both ends of a metal plate in the width direction. If both ends are vertically bent only once, they have a C-shaped cross-section, and if they are vertically bent twice, they can have a C-shaped cross-section. In the internal space, a power or signal line connected to the electronic product 160 may be disposed, and an outlet module 140 to which power or data cables are fastened may be disposed.

The outlet module 140 may include a power terminal for supplying power, a data terminal for transmitting and receiving data such as an Internet line or cable input, and a connector for connecting a functional unit inserted in the frame with another functional unit. The connector has terminals on both sides of the frame, and data can be exchanged with each other by inserting a data connection line of each electronic device into the terminal. The outlet module 140 may include a rail structure that moves along the frame modules 111, 112, and 113.

A vent hole 116 may be formed in the section steel 115 as shown in FIG. 4. The vent hole 116 may reduce the weight of the section steel 115 and discharge heat generated from the electronic product 160. In order to dissipate heat more actively, a fan can be used to discharge hot air to the outside. When the heat of the electronic product 160 is discharged indoors, a heating effect may be obtained in winter. However, in summer, a structure that discharges heat to the outside can be added by circulating heat inside by using a fan as a cause of increasing the indoor temperature, or by adding it to the wiring connected to the outdoor unit of the air conditioner.

Each frame module 111, 112, 113 may include an outer cavity forming a square around the outer circumference and an inner cavity for partitioning the mounting space 114 therebetween. The outer steel may include a vertical steel extending in a vertical direction and a horizontal steel extending in a horizontal direction. The first frame module 111 to the third frame module 113 may be assembled by arranging a horizontal steel between a pair of vertical steels. In order to fasten the vertical steel with the fixing member 120 fixed to the ceiling and the floor, it is necessary to arrange the upper and lower ends of the vertical steel to be exposed. Therefore, by placing the vertical steel outside the horizontal steel, it is possible to insert and fasten the vertical brackets 122 and 123 of the fixing member 120 to the end of the vertical steel.

The inner steel located inside the outer steel divides the space surrounded by the outer steel to form the mounting space 114, and the inner steel may be assembled so that it cannot be moved by welding to the outer steel, and some inner steels can be assembled using bolts or hooks. They can be combined so that they can be removed as needed.

In this way, by using a method of fastening between the frame modules 111, 112, and 113 in the form of the semi-finished product 160, the number of assembling in the field can be minimized. The dimensions of the product 160 can be kept constant and installation time can be reduced. In addition, because it can be modularized into a size that is easy to move, it can be easily transported to the site.

5 shows examples of various frame structures 110 according to a combination of frame modules 111, 112, and 113. FIG. 5A is a frame structure 110 in which a pair of first frame modules 111a, one second frame module 112a, and a pair of third frame modules 113 of FIG. 3 are assembled. ). Since the first frame module 111a has four mounting spaces 114, it may be difficult to install in a narrow indoor space due to its wider width.

Accordingly, as shown in FIG. 5B, a first frame module 111b having a short horizontal length including three mounting spaces 114 may be used. The second frame module 112b may have a length corresponding to the horizontal length of the first frame module 111b.

In addition, the third frame module 113 may be disposed on both sides of the first frame module 111 and the second frame module 112 vertically stacked. Since the floor height of a typical house is 220cm ~ 230cm, the height of the third frame module 113 may be configured to be a little less than 220cm. Although a five-stage vertical frame is shown in the drawing, a six-stage vertical frame may also be manufactured in preparation for a case of a double layer or a high floor height.

When installing in a narrower space, the third frame module 113 may be omitted and the frame structure 110 may be constructed using only the first frame module 111a and the second frame module 112a, or a large display device ( If 161 is not mounted, the frame structure 110 may be implemented by arranging only the third frame in a line. Each frame module 111, 112, 113 may be fastened with bolts or may be fastened by a welding method.

6 is a view for explaining a method of installing the frame structure 110 of the smart wall 100 according to an embodiment. The frame structure 110 configured by fastening the frame modules 111, 112, and 113 may be fixed to the ceiling and the floor for installation in an indoor space.

The fixing bracket 125 installed on the ceiling or floor is a member that is bent in an L-shape, and one side 125b extends in a vertical direction from the ceiling or floor and the other side 125a from the ceiling or floor. It may include a first vertical bracket 122 inserted into the inner space of the vertical cavity of the first frame module 111 and the second frame module 112.

The first vertical bracket 122 may be formed to be longer than the vertical length of the first frame module 111 so as to fasten not only the first frame module 111 but also the second frame module 112. A second vertical bracket 123 disposed parallel to the first vertical bracket 122 and inserted into the third frame module 113 may be further included. Since the vertical steel of the third frame module 113 is one member, it does not need to be as long as the first vertical bracket 122.

The coupling bracket 121 coupled to the ends of the first vertical bracket 122 and the second vertical bracket 123 may form a T-shape together with the vertical brackets 122 and 123. The coupling bracket 121 is coupled to the vertical brackets 122 and 123, and is vertical from the seating portion 121b and the seating portion 121b that are seated on the upper surfaces of the first frame module 111 and the third frame module 113. It may include a fastening portion 121a extending in the direction and fastened with the fixing bracket 125. The coupling bracket 121 and the fixing bracket 125 can be fastened using a screw, and the fastener to which the screw is fastened may be formed to be long in the vertical direction so that it can be adjusted according to the ceiling height.

When the smart wall 100 is installed over an existing wall, it may further include a fixing member 120 fastened to the existing wall.

Since the smart wall 100 has an audio device, such as the speaker 162, when it is used as a temporary wall, a space separated from the wall is generated. At this time, in order to block the sound of the two spaces, the smart wall 100 may be fixed by adding a soundproof structure so that sound does not leak to the ceiling, floor, and sidewalls in contact with the smart wall 100.

7 is a view for explaining the basket 130 of the smart wall 100 according to an embodiment. The frame modules 111, 112, and 113 may be divided into a plurality of mounting spaces 114 by using the inner section steel 115. As shown in FIG. 7, a space in which the electronic product 160 is mounted may be provided by inserting the basket 130 into the mounting space 114. The second frame module 112 has a relatively large mounting space 114 because the display device 161 is located, but the mounting space 114 of the first frame module 111 and the third frame module 113 is It can be formed in a standardized size. If the mounting space 114 of a standardized size is used, the basket 130 can also be standardized, and thus there is an advantage in that there is no need to manufacture parts having various shapes unnecessarily.

If the size of the mounting spaces are all the same, it is convenient for standardization, but a larger space may be required depending on the electronic product 160 to be mounted. For example, since the sizes of the air conditioner and the air purifier are different, the size of the mounting space 114 may be formed to be an integer multiple of the basic size in consideration of this difference. For example, a second mounting space 1142 having a horizontal size of an integer multiple of a based on the first mounting space 1141 having a horizontal size of a and a vertical size of b, or a third having a vertical size of an integer multiple of b It may include a mounting space (1143).

The size of the first mounting space 1141 in the horizontal direction corresponds to the size of the third frame module 113 in the horizontal direction, and the size in the vertical direction corresponds to the size of the first frame module 111 in the vertical direction. Here, the mounting space 114 means an internal space divided by the section steel 115, so the comparison between the size of the first frame module 111 and the size of the third frame module 113 is the difference due to the thickness of the section steel 115 Is ignored.

Since the first frame module 111 has a short length in the vertical direction, it may include only the first mounting space 1141 and the second mounting space 1142, and the third frame module 113 has a short length in the horizontal direction. Therefore, only the first mounting space 1141 and the third mounting space 1143 may be included.

8 is a perspective view showing an example of an air purifier 164 according to an embodiment. The air purifier 164 may be disposed in one of the mounting spaces 114 of the frame structure 110, and the basket 130 may be omitted by forming the outer case in a size suitable for the size of the mounting space 114 .

The air purifier 164 has openings 16461a and 16461b through which the air purified by the air purifier 164 is discharged in the art wall 150 on the front so that the air can be sucked in to remove impurities and discharge the air again. The openings 16461a and 16461b may be opened or closed or may be selectively exposed. The air purifier 164 may be located under the display device 161,

The smart wall 100 may be additionally installed on a wall, but as shown in (a) of FIG. 8, itself may serve as a wall that divides the indoor space. In this case, the openings 16461a and 16461b may be formed on both sides 150a and 150b of the smart wall 100, and the purified air discharged from the air purifier 164 is 2 Can be provided in the space of the dog. Figure 8 (a) is a first outlet (16461a) facing the living room (1st room, room 1), Figure 8 (b) is a second outlet (16461b) facing the back room (2nd room, room 2). . The positions and sizes of the first outlet 16461a and the second outlet 16461b need not necessarily be the same, and a plurality of air purifiers 164 may be mounted in the smart wall 100.

9 is a view showing a cross-section of the air purifier 164 according to an embodiment. The air purifier 164 includes a body 1641 and a filter 1643 and a blower fan 1644 positioned inside the body 1641. The blowing fan 1644 is a device that sucks air so that outside air passes through the air purifier 164, and a filter 1643 is placed between the blowing fan 1644 and the inlet, so that the air purifier 164 in the filter 1643 It can purify the air entering the interior. The blowing fan 1644 may introduce air from the front side and discharge the air from the side, as shown in FIG. 9. The blowing fan 1644 may change the direction of air flowing into the air purifier 164 and discharge it, thereby increasing the utilization of the internal space of the air purifier 164.

The air that has passed through the blowing fan 1644 is discharged to the outside again through the outlets 16416a and 16461b. The air purifier 164 is mounted on the smart wall 100 located between the first room (room 1) and the second room (room 2). Purified air can be supplied at the same time.

10 is a view showing the opening and closing of the door 310 of the smart wall 100 according to an embodiment. The smart wall 100 of the present invention can mount an electronic device in the smart wall 100 like the air purifier described above, and it is necessary to open the front of the smart wall 100 for use and maintenance of the mounted electronic device. There is. Particularly, when it is operated like an air purifier, it must be opened to communicate with the outside, or the art wall 150 located in front of the mounting space must be opened in order for the sound output such as a speaker to reach the user.

In the case of the air purifier 164, the filter needs to be replaced and the humidifier 165 needs to supply water periodically, so an openable art wall 150 is required. An art wall 150 that can be opened and closed so that the same electronic device can be completely exposed is required. Hereinafter, the openable art wall 150 is referred to as a door 310.

The door 310 may have the same color and material as the fixed art wall 150, and may be recognized by a user as a part of the art wall 150 in a closed state (first state). Since the smart wall 100 is located between the ceiling and the floor, the door 310 located in front of the mounting space located at the bottom must be opened and closed so that there is no interference with the floor, and the door located in the front of the mounting space located at the top (310) is to be opened and closed so as not to interfere with the ceiling.

Referring to FIG. 10, a door 310 that covers a mounting space located under the display device 161 is shown, but the door 310 is a mounting space located above or in the lateral direction of the display device 161. You can also cover it. The door 310 of this embodiment discloses an embodiment in which the rotation shaft 325 is located at the bottom in a form that rotates and opens and closes around a rotation shaft 325 located at one end.

FIG. 11 is a view showing a driving unit responsible for opening and closing the door 310 of the smart wall 100 according to an embodiment, and FIG. 12 is a first motor 321 part of the smart wall 100 according to an embodiment And the second motor 324 are enlarged views. The driving unit of this embodiment applies a force to the upper part of the door 310 so that the upper part of the door 310 moves while drawing an arc around the rotation shaft 325 located under the door 310 and the rotation shaft 325 It includes a first motor (321).

It includes a rotation gear 322 that rotates by receiving the rotational force of the first motor 321 and a link 323 having an internal gear engaged with the rotation gear 322. The link 323 has an arch shape in a curved shape, and since the movement of the upper portion of the door 310 moves in a curved shape, the link 323 may also have a curve corresponding thereto.

The internal gear is a kind of rack gear, and the general rack gear has a linear shape, but the internal gear of the present invention is formed on a curved surface so that the upper end of the door 310 can be moved in a curved shape when the rotating gear 322 rotates. The rotation gear 322 is positioned between the side walls protruding on both sides of the internal gear, so that the rotation gear 322 can maintain a state in which the rotation gear 322 is engaged with the internal gear. The range in which the door 310 is opened is limited according to the length of the link 323, and the longer the link 323, the more open the door 310, but the link 323 in the closed state (first state) In order to be positioned within the smart wall 100, the length is limited.

In order to solve this problem, the link 323 may be configured in multiple stages. 13 is a diagram illustrating an operation of a link of the smart wall 100 according to an exemplary embodiment, and illustrates an aspect in which multi-stage links are unfolded. In the multi-stage link, as shown in (a), in the first state, a plurality of arch links 3231, 3232, 3233 are overlapped in the thickness direction and the door 310 is opened, and the arch links 3231, 3232, 3233 are One by one, the door 310 may be opened by being withdrawn in a telescopic manner. The end of each arch gear forms an inclined surface so that the rotational gear 322 is smoothly switched from the internal gear of the first arch link 3231 to the internal gear of the neighboring second arch link 3322 You can also achieve.

Both ends of the hinge shaft located under the door 310 may be fixed to the frame structure 110 and pass through the clamp 329 located under the door 310. In order to support the weight of the door 310, a second motor 324 may be further included to assist in rotation of the hinge shaft positioned under the door 310. The second motor 324 may be connected to the rotation shaft 325 to provide rotational force to the rotation shaft 325.

A rotation lever 326 extending from the rotation shaft 325 may be further included to transmit the rotational force of the second motor 324 to the door 310. The rotation lever 326 is coupled to the inner side of the door 310 as shown in FIG. 11 and receives the rotational force of the rotation shaft 325 to control the state change of the door 310 together with the link 323. . The rotation lever 326 may be directly connected to the rotation shaft 325 as shown in FIG. 11 or is fastened with the rotation shaft 325 through a spur gear as shown in FIG. 11 (b) to rotate the rotation shaft 325 Can be synchronized with

The spur gear is a first spur gear 327 that rotates according to the rotation of the rotation shaft 325, a second spur gear 328 that rotates in engagement with the first spur gear 327 and is coupled to the lower end of the rotation lever 326 Includes. When the second motor 324 rotates, the first spur gear 327 rotates according to the rotation of the rotation shaft 325, and the second spur gear 328 rotates when the first spur gear 327 rotates. It can rotate in a fixed state without rotating along the outside of 327). The user may open or close the door 310 while the second motor 324 is not driven. In this case, the rotation shaft 325 is fixed without rotating, and the rotation lever 326 moves according to the rotation of the door 310, so the second spur gear 328 rotates along the outer circumferential surface of the first spur gear 327. can do.

14 is a diagram illustrating driving of the door 310 of the smart wall 100 according to an exemplary embodiment. When the door 310 is switched from the first state to the second state, a sensor may be used to control the driving more stably and accurately. As shown in FIG. 14, a distance sensor 351 fixed to the frame structure 110 may be provided. The distance detection sensor 351 is a device that emits a signal toward the door 310 and measures the distance to the door 310 using the time when the signal is reflected and received (distance = (reception time-transmission time)) x signal rate/2). The signal refers to microwaves including light such as infrared rays, and it is possible to determine whether the door 310 has reached the first state or the second state by using the distance measured by the distance sensor 351.

When the door 310 almost reaches the second state when switching from the first state to the second state as shown in FIG. 14(b), the speed of the driving unit is reduced to control the door 310 to slowly and naturally stop in the second state. I can. Conversely, by switching from the second state to the first state, it is also possible to control the door 310 to slowly and naturally stop in the first state by reducing the speed of the driving unit even in the state as shown in FIG. 14C. If it suddenly stops, the motors 321 and 324 may be strained, and noise may be generated that collides with the door 310 and the frame structure 110 or the floor, so speed control is required. In addition, by attaching the acceleration sensor 352 to the door 310 itself, the speeds of the motors 321 and 324 may be more accurately controlled.

When switching from the second state to the first state, a user may pinch a hand between the door 310 and the frame. To prevent this, the door 310 and the door 310 and the door 310 and the door 310 A pressure sensor 353 may be provided between the frames. When the pressure sensor 353 detects an abnormal pressure (for example, when pressure is sensed only in a portion) during the transition to the first state, the controller 180 rotates the motors 321 and 324 in the reverse direction to return to the first state. The door 310 can be controlled to open.

15 is a flowchart illustrating a method of controlling the driving of the door 310 of the smart wall 100 according to an exemplary embodiment. This is a flowchart illustrating a method of controlling the controller 180 using the driver and the sensors 351, 352, and 353 described above. First, when power is applied, the position of the door 310 is determined using the distance sensor 351 and the control signal input of the door 310 is waited (S11, S12). When the door 310 is in the open state (in the second state) and the door 310 close signal is received (S13), the motors 321 and 324 are driven to close the door 310, and the controller 180 is the door ( It is sensed by the acceleration sensor 352 located at 310) and the driving speed of the motors 321 and 324 can be adjusted (S14).

When the position of the door 310 is sensed with the distance sensor 351 (S15) and the door 310 has entered the deceleration section (section (c) of FIG. 14) (S16), the motors 321 and 324 are decelerated. At the same time, the pressure sensor 353 is activated (S31). If pressure is detected by the pressure sensor 353 before reaching the first state (closed state), it is determined as an abnormal pressure, and the object between the door 310 and the frame structure 110 or the motor 321, 324 is reversed. It can be driven (S34). After moving in the reverse direction by a specified distance, the motors 321 and 324 may be closed in the closing direction again. For example, after driving the motors 321 and 324 in the reverse direction to the deceleration section, the motors 321 and 324 can be driven in the closing direction. In this case, the speed of the motors 321 and 324 corresponds to the speed of the deceleration section. So that it closes slowly.

If the pressure is not detected by the pressure sensor 353, the motors 321 and 324 are driven in a direction that is continuously closed, and when the distance sensor 351 determines that the door 310 has reached the first state (S33), the motor ( 321, 324 and the sensors 351, 352, 353 may be stopped, and the driving of the door 310 may be terminated (S41).

When the door control signal is an open signal When the door 310 is in a closed state (S21), the motors 321 and 324 are driven in the open direction. The acceleration sensor 352 measures the speed of the door 310 and controls the door 310 to move at a constant speed (S23), and the door 310 is currently between the distance sensor 351 and the door 310 When the distance enters the deceleration section (S23, S24), the speeds of the motors 321 and 324 are decelerated (S25). When the door 310 is fully opened and enters the second state (S26), the motors 321 and 324 and the sensors 351 and 352 may be stopped and the driving of the door 310 may be terminated (S41). In the same way, the opening and closing operation of the heavy door is automatically performed using the driving part, making the opening and closing operation of the door quick and simple, and the use of the control sensor not only prevents accurate operation and safety accidents in advance, but also improves the convenience of operation. .

The above detailed description should not be construed as limiting in all respects and should be considered as illustrative. The scope of the present invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the present invention are included in the scope of the present invention.
