In order to solve this problem, Korean Utility Model Application No. 1996-057432 proposes to elevate the window glass by using an electromagnet, but the magnet is mounted on the window glass and only one side of the window to balance the center of gravity of the window glass. Since the back glass is not taken into consideration, the lifting movement of the window glass becomes unstable.

In addition, according to the Korean Utility Model Application No. 1996-057432, the mounted magnet is a linear lifting or lowering of window glass such as a torque overshoot by using a voice coil motor made of a simple intersection of the NS poles. Another problem is that it is difficult to guarantee the downward operation.

By the above configuration, it is possible to provide the driving force necessary for lifting the window glass to the maximum, thereby providing stable linearity of the window glass.

The Halbach magnet array may be formed on at least one side of the window frame with respect to the window frame. The Halbach magnet array has a structure in which magnets forming different magnetization directions are arranged to maximize the magnitude of the magnetic force, thereby improving the linearity of the window glass.

In addition, at least one window frame may be formed to move up and down in a vertical direction along a linear guide rail to provide an even force on the bottom of the window glass, but the left and right symmetry is provided to provide an even force to the bottom of the window glass. It is preferable to form dogs.

In this case, the electromagnet portion may be disposed to face the Halbach magnet array, and may be formed in a coil shape along the outside of the linear guide rail to electromagnetically interact with the Halbach magnet array.

Prior to the description of the drawings, the window control apparatus of the present invention may be mounted on a door of a vehicle such as an automobile, a bus, and the like. Of course, it can be mounted on the window.

1 and 2, the vehicle 10 may include a vehicle body 30 and a plurality of doors 50. The door 50 may include a window 52, and a window control device 100 may be provided inside the door 50.

The window control device 100 is a device for maximizing the driving force according to the opening and closing of the window and providing a stable linearity according to the rise of the window glass 120. Hereinafter, the window control apparatus 100 will be described in more detail with reference to the accompanying drawings.

The door 50 may include a window glass 120 and a window 52 opened and closed by the window glass 120. The window glass 120 may be built in the door 50 to perform a lifting movement, and may open and close the window 52 through a lifting movement.

The window control apparatus 100 may provide the maximum driving force required for the lifting movement of the window glass 120 in a low voltage manner, and guide the lifting movement of the window glass 120 in a non-contact manner to provide the window glass 120. Noise that may be generated during the elevation process can be minimized.

The window control device 100 is provided on the window glass 120 and the bottom surface of the window glass 120 to support the window glass 120 and provide a driving force for the lifting motion of the window glass 120. , The polarity of the current and the electromagnet parts 142a and 142b applied to the linear guide rail 140 and the electromagnet parts 142a and 142b including the Halbach magnet array parts 132a and 132b and the electromagnet parts 142a and 142b. It may include a control system 150 to control the.

In this case, the window 52 may include a window opening / closing sensor 53 that may determine a completely closed state of the window glass 120.

The window open / close detection sensor 53 may serve as a limit switch for determining whether the window 52 and the window glass 120 are in contact with each other so that the window glass 120 is completely closed to the window 52. The window glass 120 may be formed at an initial position where the window 52 abuts. At this time, since the window opening and closing detection sensor 53 determines whether the window glass 120 is completely closed, the window opening and closing sensor 53 may be formed at the uppermost end of the window 52 so as to contact the uppermost end of the window glass 120.

Meanwhile, referring to FIGS. 3 and 4, the window frame 130 may include Halbach magnet array parts 132a and 132b. Halbach magnet array portion (132a, 132b) may be said to be a plurality of permanent magnets are arranged in each magnetization direction.

In this case, the Halbach magnet arrangements 132a and 132b may be formed at one side of the window frame 130 with respect to the window frame 130, and most preferably at both sides of the window frame 130. Can be. Thus, by arranging the Halbach magnet arrangements 132a and 132b in different magnetization directions, the magnitude of the magnetic force generated in the permanent magnet can be maximized.

In addition, it is preferable that all the Halbach magnet arrangements 132a and 132b are formed over the entire window frame 130. Since the Halbach magnet arrangements 132a and 132b are substantially driving forces that provide polarity for the window frame 130 to move up and down, if formed only on one side of the window frame 130, the left and right equalization of the window glass 120 may be performed. Lifting can be difficult. Therefore, in order to maintain the elevated state of the window glass 120 with the right and left equal force, it may be desirable to form the Halbach magnet array parts 132a and 132b in each of the window frames 130.

At this time, the bottom of the window frame 130 accommodates the Halbach magnet array (132a, 132b), the linear guide rail 140 is provided so as to electromagnetically interact with the Halbach magnet array (132a, 132b) Can be.

The window frame 130 may move up and down or vertically along the linear guide rail 140, and in particular, the window frame 130 may be electromagnetically interacted with the Halbach magnet arrays 132a and 132b. It is preferable to form the same number as).

In addition, the linear guide rail 140 may be provided adjacent to the window frame 130, the electromagnet portion may be applied to the current so that the same polarity as the polarity of the Halbach magnet arrangement (132a, 132b) can be generated 142a, 142b. In this case, the electromagnet portions 142a and 142b of the linear guide rail 140 may be formed to face the Halbach magnet arraying portions 132a and 132b, and the induction coil is formed along the outside of the linear guide rail 140. It may be formed in the same shape.

The electromagnet portions 142a and 142b are described by way of example in the shape of a coil along the outside of the linear guide rail 140, but in some cases, the coil-shaped electromagnet portions 142a inside the linear guide rail 140. , 142b may be inserted. Alternatively, the electromagnet parts 142a and 142b may be mounted inside the linear guide rail 140.

The formed Halbach magnet arrangements 132a and 132b and the linear guide rail 140 may electromagnetically interact to serve as linear motors of the window frame 130. That is, the Halbach magnet arrangements 132a and 132b and the linear guide rail 140 may serve as driving motors for the lifting motion of the window frame 130.

In addition, the illustrated window frame 130 and the linear guide rail 140 may be described as an example in which two are formed on the bottom surface of the window glass 120, and thus, the two pairs of the window frame 130 and the linear guide rail are described. By forming the 140, positional errors, such as left and right tilting and twisting, of the window glass 120, which may occur when one window frame 130 and the linear guide rail 140 are used, may be corrected.

Meanwhile, each of the electromagnet parts 142a and 142b may be connected to the control system 150. The control system 150 may control the driving force of the window frame 130 and may provide an algorithm for controlling the polarity between the Halbach magnet arrangements 132a and 132b and the electromagnets 142a and 142b. have.

The algorithm generated in the control system 150 may apply a current in which the same polarity as the Halbach magnet arrangements 132a and 132b may occur in the electromagnet portions 142a and 142b. It is possible to maintain the balance of the force applied to the window frame 130 for elevating the window glass 120 by the above algorithm.

In addition, another algorithm generated in the control system 150 may control the current direction such that the polarity generated in the electromagnet portions 142a and 142b is opposite to the Halbach magnet arrangements 132a and 132b. . The driving force for the lifting of the window glass 120 may be controlled by another algorithm as described above.

The control system 150 may use a digital signal processor (DSP), which is a digital signal device that is easy to remove external noise and has a high processing speed.

The electromagnetic interaction between the Halbach magnet arrangements 132a and 132b and the electromagnet parts 142a and 142b as described above may provide a driving force for the window frame 130 to elevate, and at this time, a driving force generated Can occur to the maximum.

In addition, since the at least one pair of window frame 130 and the linear guide rail 140 is formed, the window glass 120 can move up and down while maintaining the linearity more stably.

Since the window frame 130 and the linear guide rail 140 may be installed without using a conventional mechanical motor, the window control device 100 may be installed in a small space. Therefore, while providing a driving force capable of elevating the window glass 120 even in a small space, it is possible to elevate the window glass 120 even at a low voltage by not using a mechanical motor.

5A and 5B are enlarged views of the Halbach magnet arrangement and the electromagnet portion of the present invention.

Referring to FIGS. 5A and 5B, the right and left magnet arrangements 132a and the left magnet arrangements 132b may be disposed on both sides of the window frame 130 in the Halbach magnet arrangements 132a and 132b, respectively. Permanent magnets in other magnetization directions can be arranged.

At this time, the magnetization direction of the magnets opposite to the window frame 130 in the magnetizing direction of the right and left magnet arraying portions 132a and 132b is arranged such that magnets having the same magnetic flux direction are arranged to make Halbach magnet arraying portions 132a and 132b. The magnetic force generated by can be further improved.

In addition, the electromagnet portions 142a and 142b provided to face the right and left magnet array portions 132a and 132b may be provided outside the Halbach magnet array portions 132a and 132b, and the electromagnet portions 142a and 142b may be provided. May include a right electromagnet portion 142a facing the right magnet arrangement 132a and a left electromagnet portion 142b facing the left magnet arrangement 132b.

The right magnet arrangement 132a, the right electromagnet portion 142a, the left magnet arrangement 132b, and the left electromagnet portion 142b formed as described above may constitute one linear motor. Likewise, the window frame 130 may serve as a driving motor capable of lifting up and down.

In this case, the gap d may be formed between the right and left magnet arraying parts 132a and 132b and the right and left electromagnet parts 142a and 142b at predetermined intervals. This applies a current having the same magnitude to the electromagnet parts 142a and 142b so that a magnetic force having the same polarity as the Halbach magnet array parts 132a and 132b is generated and thus the electromagnet parts 142a and 142b and the Halbach magnet array part ( It may be spaced apart a predetermined interval (d) between the 132a, 132b.

The air gap d formed as described above may maintain a predetermined distance between the window frame 130 and the linear guide rail 140, and as a result, a uniform force may be applied to each window frame 130.

5A and 5B, the magnetic flux directions of the right and left electromagnet parts 142a and 142b may be changed as the right and left magnet array parts 132a and 132b move.

That is, the magnetization directions of the right and left Halbach magnet arrays 132a and 132b may be fixed, and the magnetization directions of the Halbach magnet arrays 132a and 132b may be fixed when the window frame 130 is not driven. Correspondingly, magnetic flux directions of the right and left electromagnet parts 142a and 142b may be determined. At this time, when the window frame 130 is raised, the magnetic flux directions of the right and left electromagnet parts 142a and 142b may be changed to correspond to the magnetization directions of the respective magnets.

For example, in order to ascend the window frame 130 in FIG. 5A, the uppermost one of the Hallbach magnet arrangements 132a and 132b corresponds to the uppermost coil among the coils of the electromagnet portions 142a and 142b. The direction of the magnetic flux generated can be the direction of entry. In this case, when the window frame 130 is raised (see FIG. 5B), the magnet in the third of the Halbach magnet array parts 132a and 132b and the coil in the upper part of the coils of the electromagnet parts 142a and 142b may correspond to each other. In this case, the direction of the magnetic flux generated by the electromagnet parts 142a and 142b may be changed to the outward direction (●). As such, as the window frame 130 rises, the direction of the current applied to each coil of the electromagnet parts 142a and 142b is changed to interact with the Halbach magnet arrangements 132a and 132b to generate induced electromotive force. Accordingly, the direction of the magnetic flux generated in the coil is also changed.

As described above, when the magnetic flux directions of the electromagnet parts 142a and 142b are changed in response to the Halbach magnet arrangements 132a and 132b having different magnetization directions, the driving force necessary for raising or lowering the window frame 130 is maximized. It can be secured. Therefore, energy efficiency for driving the window frame 130 may be improved.

The electromagnet parts 142a and 142b illustrated in FIGS. 5A and 5B are three-phase coils, and six coils may be configured to correspond to four magnets. That is, the lengths of six coils and four magnets are the same.

In addition, the window frame 130 moves in a non-contact manner when the window frame 130 moves along the linear guide rail 140 by the air gap d between the window frame 130 and the linear guide rail 140. Friction between the guide rails 140 may be prevented. Therefore, the device capable of elevating the window glass 120 can be prevented from being damaged by friction, and as a result, the device capable of elevating the window glass 120 can be used semi-permanently.

Although the preferred embodiments of the present invention have been described above by way of example, the scope of the present invention is not limited to these specific embodiments, and may be appropriately changed within the scope described in the claims.
