Next, as shown in FIGS. 4 and 5, the drive unit 120 includes a drive motor 121 provided inside the case and a drive wheel 122 that is rotated in a forward or reverse direction by being inserted into a rotation shaft of the drive motor. .

The driving motor 121 is preferably a motor capable of rotating in a forward or reverse direction so that the first window is opened or closed by pushing or pulling the frame of the first window while the driving wheel rotates in a forward or reverse direction.

In addition, the driving wheel 122 pushes or pulls the frame of the first window while rotating by receiving the rotational force of the driving motor in a state in which one side protrudes to the outside of the case and is in close contact with one surface of the frame of the first window. open the window

The drive wheel 122 is selected from among rubber, leather, artificial leather, soft PVC or silicone to prevent an error occurring when opening and closing the first window due to slipping or slipping and to improve friction with the frame of the first window. A friction pad (not shown) made of any one material may be inserted into the outer circumferential surface, and a plurality of protrusions may be formed along the outer circumferential surface of the friction pad.

In addition, in the present invention, the fixed plate 140 is coupled in parallel to the top of the front surface of the base plate 111, and the moving plate 150 is disposed at the rear of the fixed plate along the horizontal direction. Here, the front edge of the moving plate 150 is disposed inside the case 101 and the rear edge protrudes to the rear of the case.

In addition, in the present invention, the driving motor 121 has a rotating shaft that vertically penetrates the moving plate 150 and protrudes downward, and the driving wheel 122 is vertically disposed at the bottom of the rear edge side of the moving plate. One pair may be provided on both sides of the moving plate based on the center of the moving plate to prevent slipping by securing a contact area with the frame 11 of one window.

Here, a driving gear 123 is fitted to the rotation shaft of the driving motor 121, a pair of planetary gears 125 are engaged on both sides of the driving gear, and a driven gear 124 meshing with each planetary gear is fitted to the upper end of the drive wheel 122 to prevent slipping while the power of the drive motor 121 is transmitted to the pair of drive wheels 122 at the same time, and to smoothly open and close heavy or large windows. there is.

Next, the clutch 130 moves the drive unit 120 along the width direction inside the case 101 so that the drive wheel 122 adheres to one surface of the frame 11 of the first window or is separated from the frame. .

To this end, the clutch 130 includes a clutch motor 131 provided inside the case 101, a screw 132 having a predetermined length disposed at the rear of the fixing plate 140 along the width direction, and the screw It is provided to be movable along and includes a clutch frame 133 supporting the driving wheel.

The clutch motor 131 is preferably a motor capable of rotating in forward and reverse directions so that the driving unit moves linearly and reciprocally along the width direction.

The screw 132 is connected to the rotating shaft of the clutch motor 131 and is rotated in forward and reverse directions. Here, the clutch motor 131 and the screw 132 may be connected by various methods or structures, for example, the driving gear 1311 is fitted to the rotation shaft of the clutch motor 131, and the screw ( A driven gear 1312 for receiving power is fitted to one end of 132), so that power can be transmitted while the driving gear and the driven gear are directly engaged, or the driving gear 1311 and the driven gear 1312 One or more planetary gears 1313 for power transmission may be installed therebetween.

The clutch frame 133 has an upper edge coupled vertically to the bottom surface of the moving plate 150, and a nut fixing part 1331 in which a nut N engaged with the screw 132 passes through the center to be fixed. and a driving wheel support part 1332 formed orthogonally to the nut fixing part and having a pair of driving wheels 122 vertically seated on both sides of the nut fixing part.

When the power of the clutch motor 131 is transmitted to the screw, the clutch frame 133 moves in the width direction inside the case 101 along the screw 132 via the nut N, and the clutch frame 133 ) and the moving plate 150 are moved together, the position of the driving wheel 122 is automatically changed.

Conventionally, a window having one glass window installed inside the frame was used, but recently, a window having two or more glass windows installed inside the frame has been used for the purpose of heat insulation or soundproofing.

Here, as the number of glass windows inserted into the frame increases, the thickness of the window increases, and as the thickness of the window increases, it becomes heavier, so the thickness of the rail inevitably becomes thicker, and the gap between the rail and the rail according to the thickness of the window. It can only be different.

The clutch 130 changes the position of the driving wheel 122 inside the case 101 so that the driving wheel 122 is not affected by the thickness of the window disposed on the sliding window, the thickness of the rail, or the distance between the rails. By tightly adhering to the frame of the first window, smooth opening and closing is achieved while preventing slip due to play.

On the other hand, in the present invention, the drive motor 121 and the clutch motor 131 can precisely control the rotation direction, rotation amount, rotation speed, etc., and increase the power so that they are not affected by size or weight. It is preferable to use a servo motor.

In addition, the present invention includes a guide pin 160 fixed along the width direction between the fixing plate and the inner wall of the case, a guide bracket 170 preventing shaking of the moving plate and guiding linear movement, and the fixing plate and an elastic spring 180 fitted to the guide pin between the guide bracket.

When the moving plate 150 is moved by the power of the clutch motor, the guide pins 160 are paired along the horizontal direction so that the moving plate 150 does not shake while maintaining a left and right balance through a guide bracket 170 to be described later. They are spaced apart at predetermined intervals.

The bottom surface of the guide bracket 170 is coupled to the moving plate and moves along the moving plate, but the guide pin is inserted through the upper center to guide the moving plate to move in a straight line without shaking.

In FIG. 6, reference numeral 101 denotes the front surface of the case, and the guide bracket 170 is spaced apart from the front inner wall of the case when the drive wheel 122 is spaced apart from the frame 11 of the first window. are spaced apart, and at this time, the elastic spring 180 is compressed by the guide bracket 170.

In addition, when the moving plate 150 is moved by driving the clutch motor 131, the elastic spring 180 is restored to its original state and elastically supports the guide bracket 170, acting on the guide bracket 170. The force acting on the moving frame 150 keeps the driving wheel 122 firmly in close contact with the frame 11 of the first window at all times.

The frame surrounding the window appears to be a flat plane when viewed with the naked eye, but has irregularly fine curved parts (or depressions). Accordingly, when the drive wheel 122 pushes or pulls the frame 11 of the first window, when the protruding curved portion of the frame surface and the drive wheel come into contact, the drive wheel is pushed backward, causing overload of the motor. , slip may occur due to a minute gap when the driving wheel faces the recessed part recessed inward. In the present invention, the driving wheel 122 is elastically supported by the elastic force of the elastic spring 180 and is always firmly adhered to the frame 11 of the first window, thereby preventing overload and durability of the driving motor. It can be prevented, and there is a remarkable effect of preventing slip due to play.

Next, FIG. 7 is a schematic illustration for explaining a control system for a sliding window through an automatic ventilation system for a sliding window according to the present invention. The present invention includes an automatic ventilation system 100 and a terminal 200 And, it includes a control unit 300.

The automatic ventilation device 100 follows the configuration described above, and a detailed description thereof will be omitted.

The terminal 200 is installed with an application provided with a function capable of automatically opening and closing the first window, and the application can be installed and driven from the outside based on the Internet of Things (IOT) It may be a device capable of opening or closing the first window by controlling a motor, for example, any one selected from among smart phones, tablet PCs, mobile phones, desktops, laptops, tabbooks, and PDAs. In the drawings to aid understanding of the present invention, a smart phone is shown as an example as a terminal.

In addition, the terminal 200 is provided with a control unit 210 through a display unit 220 for outputting a control signal. 8 is an exemplary view showing a state in which an application installed in the terminal is executed according to an embodiment of the present invention, and the operation unit 210 'closes the window' so that the degree of opening and closing of the first window can be selected according to the user's needs. , 'slightly open', 'half open', and 'wide open' buttons may be provided, respectively, a button for selecting activation/deactivation of a locking device (crescent) to be described later, and setting/disabling of security functions. Buttons for each may be provided.

The controller 300 receives a control signal input through the application and controls a driving motor according to the received control signal to automatically open and close the first window.

The control system for sliding doors according to the present invention, including the automatic ventilation device 100, the terminal 200 with installed applications, and the control unit 300, has a security function to prevent unauthorized entry into the room from the outside. to provide.

The security function is activated through an application, and when the security function is activated by a user, a control signal is transmitted to the control unit 300, and the control unit 300 preferentially operates the driving motor 121 according to the received control signal. After the first window 10 is closed, the driving motor 121 is stopped, and the clutch motor 131 is operated to bring the driving wheel 122 into close contact with the outer circumferential surface 11 of the frame of the first window.

When the driving wheel 122 adheres to the frame 11 of the first window, the movement of the first window 10 is restricted by the driving wheel. Here, if an external force for arbitrarily opening the first window is applied, the rotation shaft of the drive motor 121 is forcibly rotated by the drive wheel, and a current value due to the random movement is detected and transmitted to the control unit 300.

The control unit 300 transmits a signal informing of external intrusion to the terminal to immediately convey the fact to the user, and can notify the surroundings of the intrusion while outputting a warning sound or lamp to request help.

As described above, the present invention can safely protect the room even when going out through the security function.

In addition, a position detection sensor 190 for detecting the first window is provided on one side of the automatic ventilation device 100 according to the present invention.

The position detection sensor 190 is provided on the side of the case 101, and the detection piece 400 faces the position detection sensor at a position adjacent to the side wall of the window frame on the outer circumferential surface of the frame 11 of the first window. this is combined

The position detection sensor 190 detects the detection piece 400 at a facing position and transmits a detection signal to the control unit. For example, the position detection sensor 190 outputs infrared rays or ultrasonic waves toward the detection piece 400, and detects that the output infrared rays or ultrasonic waves are reflected by the sensing piece 400 and returns to the position of the first window. The value is converted into an electrical signal and sent to the control unit. Since this principle is widely used in various fields, a detailed description thereof will be omitted.

On the other hand, the position detection sensor 190 may be provided on both sides of the case so as not to be affected by the arrangement of the first window 10 and the second window 20 and the position where the automatic ventilation device 100 is installed. there is.

In addition, the control system of the sliding door type window according to the present invention provides an opening/closing degree selection function capable of opening the first window by a predetermined distance desired by the user through the position detection sensor 190.

The opening/closing degree selection function is activated through an application installed in the terminal, and the control unit receives the electric signal received from the position detection sensor and the current position of the first window when a desired distance value is input through the opening/closing degree selection function of the application. After comparing, a control signal is output to rotate the driving motor in the forward or reverse direction, and when the first window reaches a desired position by the user, the power is turned off.

For example, when a user activates an opening/closing degree selection function by executing an application installed in the terminal, the control unit 300 first operates the automatic ventilation device 100 so that the sensing piece 400 detects the location of the position detection sensor 190 The first window is opened to a position closest to the first window, and then the first window is closed.

At this time, the position value at which the detection piece 400 is closest to the position detection sensor 190 ('widely open') and the maximum distance ('window closed') are stored as reference values in the control unit 300, Based on the two values, when a 'half-open' control signal is input, a corresponding control signal is output to control the driving motor. In addition, in the case of the 'open slightly' control signal, the opening and closing width can be set as much as the user desires and controlled by the control unit.

In addition, although not shown in the drawing, the present invention is installed on a window, an automatic ventilation device, or indoors and outdoors, and is electrically interlocked with the driving motor and the control unit so that the driving motor is operated by the sensing value to automatically open and close the first window. It may include a kind of sensor (hereinafter referred to as 'sensor unit'). For example, an air pollution measurement sensor that can detect the degree of contamination of indoor and outdoor air, a temperature sensor that detects outside temperature, a humidity sensor that detects humidity, an illuminance sensor that recognizes light or detects the amount of light, and in case of fire A fire detection sensor that detects smoke or flame, a gas sensor that detects leakage of a specific gas, etc. Automatic ventilation according to the operation of the sensor can be made. The value sensed by the sensor unit may be displayed on the display unit 220 in the form of phrases, numerical values, graphs, images, and the like.

On the other hand, in general, a cresent, also known as a locking device for windows and doors, is installed on a sliding window for a crime prevention function, as shown in FIG. A crescent bracket is installed.

The crescent serves to prevent the sliding movement of the randomly moving window by fastening the moving window to the fixed window while being engaged with the crescent bracket.

However, such a conventional locking device (Crescent) had cumbersome and inconvenient problems because the user had to manually move to the sliding window and manually operate the movable window, and it was impossible to control the locking device from the outside.

11 is a schematic illustration showing a locking device for sliding doors controlled through the application according to an embodiment of the present invention.

As shown in FIG. 11, the locking device is installed on the side of the frame 21 of the second window and includes a main body 510 having a dead bolt 511 protruding outward while moving along the width direction, and the main body It is installed on one side of the first window to correspond to and includes a clasp 520 in which a dead bolt insertion hole 521 into which the dead bolt is inserted is formed.

In addition, the application according to the present invention provides an automatic locking function for fixing the first window 10 by outputting a control signal so that the dead bolt protrudes outward from the main body and is inserted and fixed into the dead bolt insertion hole 521. .

The main body 510 has an approximately rectangular shape with an empty interior so that components for electrical movement of the dead bolt, components for supplying power to the dead bolt, and components for wireless transmission and reception with the control unit 300 may be mounted. It may be made of, and brackets in which bolt holes are formed may be formed at the upper and lower sides of the side so that the bolts are fastened to the frame of the second window.

The clasp 520 is coupled to the first window 10 or the second window 20 to correspond to the main body so that the dead bolt insertion hole 521 faces the dead bolt 511, for example, It may be adhesively bonded to the glass window of the first window with double-sided tape or the like, or bolted to the side of the frame 21 of the second window.

In the present invention as described above, when the automatic locking function of the application installed in the terminal is activated, a control signal is output and the dead bolt 511 is inserted and fixed into the dead bolt insertion hole 521 to restrict the movement of the first window. Through this, the user can solve the hassle of having to directly move to the sliding window and operate the locking device, and there is a remarkable effect of controlling the indoor (inside) sliding window in the locked state even from the outside.

On the other hand, in the control system for sliding doors according to the present invention, when the security function is activated through an application, the automatic locking function is sequentially activated, the first window is closed, and then the dead bolt 511 is inserted into the dead bolt insertion hole 521. As it is fixed, the security function can be further improved.
