The automatic opening and closing device 30 having such a configuration was automatically opened and closed using a control box or a manual switch 34.

That is, after driving the roller 33 by the motor 31, the roller 33 is rotated on the rail (not shown) of the lower window frame frame 12 to open and close the window 10 The window 10 is opened and closed by a friction force between the roller 33 and the rail (not shown).

However, as described above, opening and closing of the window is caused by a frictional force, and when the roller 33 slides and rotates on the rail, accurate position control is difficult and the roller 33 is in contact with the rail. There was a problem that the rails are contaminated to damage the beauty.

In addition, the roller 33 and the rail is in contact with the wear caused by the wear has a problem that the durability is deteriorated, the size of the window due to the motor or a large space is required, there is a problem that the freedom of design is inferior.

And an automatic opening and closing device of a window and door using a coreless brushless servo motor which opens and closes the window by the interaction of the coreless coil unit with the coreless coil unit.

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

The present invention uses the principle of the coreless brushless servo motor as described above, and installs the coreless coil part and the reaction plate on the window frame and the window, respectively, and the attraction force generated by the coil part and the reaction plate interaction. The present invention relates to a device that can automatically open and close windows without using mechanical contact between the window frames and the windows using repulsive force.

The rushless servo motor is a type of synchronous motor, and the synchronous motor is composed of a stator and a rotor, and uses a permanent magnet to provide rotational force. It refers to the generating motor. These synchronous motors are characterized by low electrical or mechanical noise, high reliability, easy control of speed and acceleration, and high thrust force.

On the other hand, the brushless motor which removes the brush used in the synchronous motor uses an alternating current power source and uses the principle of inverting the polarity of the power source by the position of the rotor.

In particular, it is a brushless servo motor that is used for automatic opening and closing of windows and doors as the present invention, as is generally known, by using the concept of the brushless motor to generate a linear force rather than a rotational force.

As shown in FIG. 2, the brushless servo motor described above includes a reaction plate 120 and a coil unit 110. The reaction plate 120 includes a magnetic 122 disposed on the stator 121, and the coil unit 110 includes a coil 111 mounted on the yoke 113. As described above, in the present invention, a coreless coil unit using no core is used. In the case of a coreless coil unit not using the core, the coreless coil unit does not have a resolution limitation, and thus, precise control is possible. Since the core 111 is not mounted, the installation shape of the coil 111 is free, so that the shape of the coil unit 110 can be freely designed, thereby improving design freedom and improving productivity.

When power is applied to the coreless coil unit 110 having the above-described configuration, an electromagnetic field is generated, and attraction or repulsion is generated between the coreless coil unit 110 and the reaction plate 120. Alternatively, the technical idea of opening and closing the window 10 using repulsive force is the present invention.

Hereinafter, the present invention using the coreless brushless servo motor will be described in more detail with reference to the following embodiments.

Example 1

In the first embodiment, the brushless servo motor is applied to the lower window frame 12 and the lower window frame frame 22.

As shown in FIG. 3, a lower window frame 12 in which glass G is accommodated is disposed on the lower window frame frame 22, and the above-described conventional roller 33 is disposed below the lower window frame 12. It is also possible to be mounted, wherein the roller 33 is in contact with the rail (22a) formed in the lower window frame frame (22).

On the other hand, the lower window frame frame 22 is provided with a planar flat reaction plate 120 and the coreless coil unit 110 is mounted on both sides of the roller 33 of the lower window frame 12. At this time, the flat reaction plate 120 and the coreless coil unit 110 are as described above.

In this case, when power is applied to the coreless coil unit 110, an electromagnetic field is formed, whereby the coreless coil unit 110 and the reaction plate 120 are subjected to an attractive force or repulsive force due to interaction. The windowless 110 in which the coreless coil unit 110 is installed is driven and the roller 33 serves to help the driven window 10 to be driven more smoothly.

In this configuration, the window 10 and the window frame 20 are not opened and closed by the driving of the roller 33 using friction force as in the prior art, but are driven in a non-contact manner by electromagnetic force. The controllable and non-contacting method has the effect of improving durability.

In the first embodiment, the coreless coil unit 110 is installed in the window 10 and the reaction plate 120 is installed in the window frame 20. However, the reaction plate 120 is installed in the window 10. It is also possible to install the coreless coil unit 110 in the window frame 20. As a result, since the attraction force or repulsive force generated between the coreless coil unit 110 and the reaction plate 120 may be changed in position.

That is, as shown in FIG. 4A, the coreless coil unit 110 is installed on the lower window frame frame 22, and the flat reaction plate 120 is installed on the lower surface of the lower window frame 12. The window is automatically opened and closed by such a configuration. At this time, since the minimum coil unit 110 is installed as shown in FIG. 4B, there is an economically advantageous effect.

Meanwhile, in the case of using a coreless brushless servo motor in a window as in the present invention, a motor drive and a controller for controlling power are required. The motor drive and the controller are obvious components to those skilled in the art, so detailed descriptions thereof will be omitted. do.

Example 2

In the second embodiment, the brushless servo motor is applied to the upper window frame frame 21 and the upper window frame frame 11 positioned above the window frame 20 and the window frame 10.

As shown in FIG. 5, the U-shaped reaction plate 130 including the stator 131 and the magnetic 132 is installed in the upper window frame 11, and the coreless coil part is installed in the upper window frame frame 21. 110 was installed.

The coreless coil unit 110 has the same configuration as the coreless coil unit 110 of the first embodiment, and the molding unit 114 and the molding bracket 115 are mounted to the upper window frame frame 21. Added the configuration.

That is, the molding part 114 surrounds the coreless core part 110 by a molding process, and the molding part 114 is mounted to the upper window frame frame 21 by a molding bracket 115. .

The molding bracket 115 includes a molding bracket base 115a mounted on the upper window frame frame 21 and a pair of vertical extensions 115b extending downward from the molding bracket base 115a and extending toward the window side. It is composed.

At this time, the molding part 114 is inserted between the pair of vertical extension parts 115b, so that the coreless coil part 110 embedded in the molding part 114 is fixed. In this case, the coreless coil unit 110 does not have a core as described above, and thus has an effect of improving design freedom.

On the other hand, the "U" shaped reaction plate 130 is composed of a stator 131 and a magnetic 132 mounted on the stator 131, the same configuration as the reaction plate 120 of the first embodiment .

On the other hand, the position adjusting portion 200 is composed of a plurality of rollers 210 on the side end of the reaction plate 130, which will be described below with reference to FIG.

In FIG. 6, two of the plurality of rollers 210 are illustrated as an example.

The roller 210 is rotatably installed on the roller bracket 220 mounted on the “U” shaped reaction plate 130, wherein the roller 210 is not at the same center line. In other words, some of the positioning rollers 210 are installed to rotate in contact with the molding bracket 115 as shown in FIG. 5, and the other positioning rollers 210 are opposite to each other, that is, outside of the upper window frame frame. It is mounted to the rail 26 side.

By this configuration, the window 10 may be maintained in a constant direction to minimize the left and right flow. In other words, when power is applied to the coreless coil unit 110, an electromagnetic force is generated. In this case, the “U” shaped reaction plate 130 is applied to the window 10 to which the reaction plate 130 is mounted. ) May be attached to the molding bracket 115 side or the outer rail 26 side of the window frame, and when the pole of the power supplied by the motor drive is changed, the window 10 moves to the left and right.

In order to prevent such a phenomenon, if the roller 210 is installed on both sides as described above, even when trying to stick to any of the left and right sides, it will be driven without oscillation.

Meanwhile, as shown in FIG. 5, the encoder 313 is preferably mounted on one side of the reaction plate 130. In this case, the encoder 313 enables position measurement, thereby enabling accurate control.

Of course, as shown in FIG. 4, when the sensor bracket 312 is installed on the reaction plate 130 and the position sensor 311 is mounted on the sensor bracket 312, the operation limit of the window 10 is recognized. You can do it.

Also in the second embodiment, the coreless core 110 and the reaction plate 130 may be interchanged and mounted in the same manner as in the first embodiment.

As described above, the conventional method is to open and close the window by driving a roller installed in the lower window frame, so that the roller is slipped on the rail, so that accurate position control is difficult and the roller is in contact with the rail. There was a problem that the rails are contaminated to damage the aesthetics. In addition, wear and tear caused by the contact of the roller and the rail, there was a problem that the durability is deteriorated, there is a problem that the freedom of design, such as the size of the window or the large space is required due to the motor is falling,

As shown in the present invention, after installing the coreless coil portion and the reaction plate on the window frame and the window sill, the windows can be opened and closed automatically using the attraction force or the repulsive force generated by the coreless coil portion and the reaction plate interaction. By the configuration, the window frame and the window frame can be opened and closed without mechanical contact, enabling accurate position control, preventing contamination of the rail, and preventing abrasion by non-contact method, improving durability, and not using a conventional mechanical motor. There is an effect that can improve the degree of freedom of design, such as is not limited in size.

In addition, due to the use of the brushless servo motor, the electrical and mechanical noise is small and the reliability is high, so it is easy to control precisely. Also, the core force is obtained by using the coreless coil part. Precise control is possible because there is no caulking, and there are few shape constraints to improve design freedom and productivity.
