Description

Motor-driven active windows and doors having semiautomatic operation mode

The present invention relates to a window that automatically opens and closes, and in particular, the window that is automatically opened and closed by the power source and the power transmission mechanism can be opened and closed more easily by receiving the assistance of the force generated from the power source. In addition, the present invention relates to active windows and doors that can detect and proactively open and close windows when events of environmental changes such as noise or harmful gases are generated.

In general, sliding windows installed in the living room or balcony of the apartment are opened and closed by a user's hands open and close in most cases. Therefore, if the window must be opened and closed to control room temperature or ventilation, or to block the noise generated from the outside, a person must move directly to the window and then open and close it. This is not too difficult for many people, but it is often not easy for patients with disabilities, disabled people or the elderly.

Moreover, in recent years, sliding windows installed in apartment living rooms or balconies tend to become larger in size, as well as double or triple glass windows with several layers of glass for sound insulation or heat insulation, so the weight is quite heavy. It's getting harder and harder to say that work is easy for the general public.

Therefore, in order to solve the above problems, various types of automatic systems have been proposed to open and close the windows more comfortably. For example, by operating the driving means using a remote controller, the windows can be easily and automatically changed as necessary. Several automatic systems have been developed which can be opened and closed, and the driving means of such automatic systems is to allow the windows to slide horizontally by the rotation of the chain belt, or to rotate the pinion gear coupled to the drive motor. It is transmitted to the rack gear so that the window can be slid to the horizontal axis.

1 relates to a "automatic opening and closing window" disclosed in the Republic of Korea Utility Model No. 382598, the automatic opening and closing window is a mobile window 140 and the fixed window 142 is coupled to the window frame 150, the mobile window ( Rack gear 120 is coupled to the upper surface of the 140 is engaged with the pinion gear 110 is rotated by the drive motor 100 to rotate the movable window 140 by the rotation of the drive motor 100 It is configured to move to.

However, such a conventional automatic opening and closing window has some parts that need to be improved.

First, it is convenient in that the window can be opened and closed automatically by operating a remote control or switch, etc., but there is a problem that opening and closing the window manually becomes inconvenient. This means that in order to open and close a window manually, the power source (eg drive motor) and power transmission mechanism (eg rack and pinion mechanism) used to automatically open and close the window must be driven by human power in reverse. Therefore, more force is input when opening and closing the window manually than without the automatic opening and closing mechanism.

Second, since the conventional automatic opening and closing window has a configuration of automatically opening and closing the window by operating a remote control or a switch, the operation can be started only when a start signal of the window opening and closing operation is generated by a person in any way. That is, the conventional automatic opening and closing window is not active actively. However, since a power source and a power transmission mechanism are already provided in a conventional automatic opening and closing window, the addition of an automatic control device has the possibility of constructing an automatic opening and closing window that can be actively operated in response to changes in the surrounding environment. I have it. Therefore, the prior art has a limitation that does not fully utilize the potential of the automatic opening and closing window.

The present invention for solving the problems of the prior art as described above, so that the windows and windows automatically opened and closed by the power source and the power transmission mechanism can be opened and closed more easily by receiving the assistance of the force generated from the power source. It is for one purpose.

In addition, another object of the present invention is to enable the detection and active opening and closing of windows and doors when an event of a change in the surrounding environment such as noise or harmful gas is generated.

Active window having a semi-automatic mode according to the present invention, the window frame consisting of a rectangular frame; and is fixed to the left and right to move along the window frame, the gripper is provided on one side of the external force applied to the handle A moving window including a sensor detecting a direction of a left side or a right side of the handle; and a first pulley and a second pulley fixed to the left side and the right side of the upper side of the window frame to be rotatable; A belt wound around the first pulley and the second pulley; and a driving motor connected to one of the pulleys of the first pulley and the second pulley; and a fixing member for fixing the belt so as not to move on the upper surface of the moving window. And, Event detection sensor for detecting a change in the external environment, including the generation of noise or harmful gas; And when the change of the external environment more than a predetermined reference value is detected by the event detection sensor to operate the drive motor to open and close the moving window, or if the sensor provided in the handle detects the external force to operate the drive motor And a control unit for transferring the belt in a direction in which the external force is applied.

At this time, the handle may be a rotary handle, in this case, the sensor included in the rotary handle is a rotation direction detection sensor.

Alternatively, the handle may be a fixed handle, in which case the sensor included in the fixed handle is a strain gauge for detecting deformation caused by external force applied to the handle.

On the other hand, the control unit may control the drive motor to be driven with a torque less than the maximum stop friction torque of the moving window when the sensor provided in the handle senses the external force.

Alternatively, the controller may control the driving motor to be driven with a torque less than the movement friction torque of the moving window when the sensor provided in the handle senses an external force.

On the other hand, if the sensor provided in the handle senses an external force, the controller controls the drive motor to be driven with a torque that exceeds the movement friction torque of the moving window and less than the maximum stop friction torque, the belt moves When it starts, the drive motor may be controlled to be driven with a torque less than the movement friction torque of the moving window.

The driving motor may further include a clutch, and the controller may control the clutch to block power transmission when it is determined that the sensor included in the driving motor, the handle, or the event detection sensor is abnormal.

Here, the event sensor may be a microphone for measuring the volume, or a gas sensor for measuring the harmful gas.

The present invention having the above configuration has the advantage that the windows can be opened and closed more easily by receiving the assistance of the force generated from the power source when the windows automatically opened and closed by the power source and the power transmission mechanism is manually operated.

In addition, the present invention has the advantage that it is possible to maintain a more comfortable atmosphere of the interior space without the intervention of people by detecting and actively opening and closing the window when an event of the change of the surrounding environment, such as the generation of noise or harmful gas occurs. have.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 shows the overall configuration of an active window 1 with a semi-automatic mode according to the invention.

As shown in FIG. 2, the exterior of the active window 1 according to the present invention is fixed to the window frame 10 having a rectangular frame like the general window, and movably from side to side along the window frame 10. It consists of a moving window 20, which is provided with a gripper 22 on one side thereof. Herein, the present invention further includes a sensor 24 which detects whether the external force applied from the outside of the handle 22 is directed to the left side or the right side, which is the sliding direction of the moving window 20. There is a characteristic. In other words, the sensor 24 included in the handle 22 detects a direction in which a person grasps the handle 22 and slides the movable window 20, so that the intention of the person holding the handle 22 moves. This is to determine whether the window 20 is to be opened or closed.

In addition, the window frame 10 is provided with a power unit and a power transmission mechanism for opening and closing the moving window 20 automatically or semi-automatically. That is, the first pulley 30 and the second pulley 32 are fixed to the upper inside of the window frame 10 so as to be rotatable, respectively, on the left side and the right side thereof, and the first pulley 30 and the second pulley 32 are rotatable. The belt 40 is wound around the pulley 32. In addition, the pulley of any one of the first pulley 30 or the second pulley 32 is connected to a drive motor 50 that is a power unit, the drive motor 50 is provided with a reducer (not shown) It is preferable. In addition, the belt 40 is fixed so as not to move on the upper surface of the moving window 20 by the fixing member 26, when the driving motor 50 is driven by this configuration any one pulley ( 30 or 32 is rotated, and when the belt 40 is moved to the left or right by the rotation of the pulley, the moving window 20 connected to the belt 40 and the fixing member 26 along the window frame 10. Is sliding.

Automatic opening and closing of the moving window 20 as described above can be initiated by the operation of the remote control or switch as in the prior art, but the present invention is an event for detecting a change in the external environment, including the generation of noise or harmful gases And a control part 70 for controlling opening and closing of the moving window 20 when the signal value acquired by the sensor 60 and the event sensor 60 is equal to or greater than a predetermined reference value. have.

That is, the event sensor 60 is a generic term for a sensor for detecting a kind of event that a change has occurred in the external environment, and typically, it is unpleasant to people by measuring the volume of sound generated from the outside. For example, a microphone that provides information to determine if it is possible noise, or a gas sensor that detects whether a harmful gas has occurred indoors. In addition, rain detection sensor for detecting precipitation, solar radiation sensor for detecting the amount of insolation, temperature sensor for detecting temperature changes in the room, dust sensor for measuring the amount of dust such as yellow sand, or oxygen sensor for measuring the amount of oxygen in the room, etc. Many types of sensors can be included in the category of event detection sensors.

More specifically, when the outside noise measured by the microphone exceeds the value set as a reference value (for example, 80㏈) or the amount of dust measured by the dust sensor exceeds the reference value, the moving window 20 is closed and noxious gas is released from the room. When the generated or oxygen amount is insufficient, it is possible for the control unit 70 to control the operation of the drive motor 50 to open the moving window 20 for ventilation.

In addition to the automatic and active opening and closing of the moving window 20 as described above, the present invention receives the assistance of the force (torque) generated by the drive motor 50 when opening and closing the moving window 20 manually. It may be configured to open and close the moving window 20 more easily. This is a kind of semi-automatic mode, in which the control unit 70 receives a signal output from the sensor 24 included in the handle 22 and the control unit 70 drives the driving motor according to the signal output from the sensor 24. By controlling 50. In the embodiment of the present invention, the signal output from the sensor 24 is configured to be input to the controller 70 via the fixing member 26, the belt 40 and the drive motor 50.

As described above, the sensor 24 included in the handle 22 of the moving window 20 has a handle 22 and the intention of the person to slide the moving window 20 is to open the moving window 20. Since the controller 70 outputs a signal capable of determining whether or not it is going to be closed, the controller 70 drives the belt 40 to move the belt 40 along the direction in which the movable window 20 is opened or closed according to the signal. By driving), it becomes possible to assist the operation of opening and closing the moving window 20 manually. Of course, when the external force is no longer applied to the handle 22, the operation of the drive motor 50 is stopped.

Here, the handle 22 is called the rotary handle 22 ', and as shown schematically in FIG. 2, the sensor 24 included in the rotary handle 22' is a rotational direction detecting sensor 24 ". The rotation direction detection sensor 24 "is a sensor that outputs two types of signals that are distinguished from each other according to a clockwise or counterclockwise rotation. In the present invention, it is sufficient to distinguish only the rotation direction and to measure the rotation angle. Since it is not necessary, it is possible to use a relatively inexpensive rotation direction detection sensor 24 ".

In addition, as shown in FIG. 3, the handle 22 may be a fixed handle 22 ″, in which case the sensor 24 included in the fixed handle 22 ″ is the fixed handle 22 ″. It is a sensor for detecting whether the external force applied to the left or right. The sensor 24 may be composed of a pair of pressure sensing sensors (not shown), respectively provided on the left and right sides of the fixed handle (22 "), The controller 70 may determine that the moving window 20 is to be moved in a direction in which a greater pressure is detected among the left pressure sensor and the right pressure sensor. Alternatively, the sensor 24 included in the fixed handle 22 "may be composed of a strain gauge 24" for detecting deformation due to the action of an external force, which is an advantage of the fixed handle 22 ". It is sufficient if it is provided only in either of the left and right sides of "). Because the strain gauge 24 "can distinguish the amount of deformation due to compression and tension through a negative amount of deformation (compression) and a positive amount of deformation (tensile), so that if the strain gauge 24" is a fixed handle 22 ") Is provided on the left side, if a negative deformation (compression) is detected, because it is possible to determine that the moving window 20 is moved to the left. Of course, if a positive deformation amount (tensile) is detected, It means that the moving window 20 moves to the right.

On the other hand, in the case of manually opening and closing the moving window 20, the control unit 70 supplies power to the drive motor 50 to drive it, and at this time, by adjusting the voltage of the power provided to the drive motor 50 to drive The output torque of the motor 50 can be adjusted. This output torque can be adjusted to be in a certain range, which means that the external force assisting the manual opening and closing of the moving window 20 can have an appropriate value.

A range of output torques that can be considered first is that the drive motor 50 outputs a torque less than the maximum stop friction torque of the moving window 20. Therefore, the moving window 20 cannot slide to the left or right by driving only the driving motor 50, but if a person exceeds the maximum stop friction torque by applying a slight external force, the moving window 20 is Slides easily.

However, if the output torque of the drive motor 50 is less than the maximum stop friction torque of the moving window 20 but greater than the movement friction torque, after the moving window 20 starts to move, even if no external force is applied, Will move. This may be said that a person does not manually open and close the moving window 20, and when an external force is added to the person, the moving window 20 may slide too quickly, which may be inconvenient. Therefore, it may be desirable to set the range of the output torque of the drive motor 50 to a torque range less than the kinetic friction torque smaller than the maximum stop friction torque of the moving window 20.

Finally, the range of the output torque that can be considered is that when the belt 40 starts to move after controlling the torque range that the motion friction torque of the moving window 20 is exceeded and less than the maximum stop friction torque, the drive starts. The motor 50 is to be controlled so as to be in the torque range less than the frictional torque of the moving window 20. This is because the maximum stop friction is greater than the exercise friction force, if only the torque of the movement friction torque at the beginning of the moving window 20 is moved, because a lot of force is initially entered to open and close the mobile window 20 manually. This is because you may feel somewhat inconvenient to use. Of course, once the movable window 20 starts to move, the output torque is lowered to a range less than the movement friction torque, so there is no inconvenience in manually opening and closing the movable window 20.

In addition, the driving motor 50 may further include a clutch (not shown). In this case, the controller 70 may include the sensor 24 or the event included in the driving motor 50 or the handle 22. When it is determined that there is an abnormality in the detection sensor 60, the clutch may be controlled to block power transmission. This is because when an abnormality occurs somewhere in the various devices constituting the active window 1 according to the present invention and needs to open and close the mobile window 20 manually, the mobile device is manually disconnected from the power transmission device. (20) can be said to be a kind of safety device to ensure that excessive force is not required to open and close. Herein, since the control unit 70 self-diagnoses the abnormality of the drive motor 50 or the various sensors 24 and 60, a structure that is already widely known and used in the art, a detailed description thereof will be omitted.

While the invention has been illustrated and described in connection with specific embodiments, it will be understood that various modifications and variations can be made without departing from the spirit and scope of the invention as defined by the appended claims. Anyone who owns it can easily find out.

In particular, although the present invention has been described with reference to a window, it will be apparent to those skilled in the art that the configuration of the present invention described in the detailed description can be applied to a general door having a structure similar to that of the window. In other words, it should be noted that the present invention can be applied to all general windows and doors.
