Power conversion means 30 that is rotated by the rotation shaft 20 is installed in the center of the rotation shaft 20, the driving of the bearing 41, 51 is supported on the rotation shaft 20 on both sides of the power conversion means (30) Pulleys 40 and 50 are respectively installed. The drive pulleys 40 and 50 have connecting gears 42 and 52 protruding to the inner side (power conversion means side).

The power conversion means 30 preferably uses a conventional synchro mechanism consisting of a hub 31, a synchronizer key 32, a C ring 33, a synchronizer 34, and a sleeve 35. The connecting gears 42 and 52 of the drive pulleys 40 and 50 are engaged with the threaded portion 35b formed on the inner circumference of the sleeve 35. An operating groove 35a is formed around the outer center portion of the sleeve 35.

When the sleeve 35 of the synchronizer wiper of the power conversion means 30 is selectively engaged with the coupling gears 42 and 52 of the drive pulleys 40 and 50, the gear part 35b of the sleeve 35 synchronizes with the synchronizer. It is smoothly moved by the nyper key 32 and the synchronizer 34 to be connected to each of the connecting gears 42 and 52 quickly and without noise, so that the windows 48 and 58 can be opened and closed correctly. Bracket 60 is provided on one side of the converting means 30, and the solenoids 70 and 80 are respectively fixed to the front and rear sides of the bracket 60 respectively. A shift rod 90 is installed between the opposing solenoids 70 and 80, and both ends of the shift rod 90 are inserted into the solenoids 70 and 80 to solenoids on the side to which power is applied. It is configured to move, and return springs 72 and 82 are provided to move to the neutral position when the solenoid power is turned off.

Meanwhile, the center of the shift lever 100 is hingedly coupled to the end of the bracket 60 by bending the upper center of the upper portion of the bracket 60, and the tip of the shift lever 100 is an operating groove 35a of the sleeve 35. ) Is inserted. A long hole 104 is formed at the rear end of the shift lever 100 so that the connecting pin 92 protruding from the shift rod 90 is inserted.

On the other hand, idle pulleys 43, 44, 54 and 54 which are fixed in an idle state on the upper left and right sides of the upper left window 58 and the right window 48 of the window installation part are respectively installed. In addition, the drive pulley is connected to the idle pulley and the belt 45, 55 installed on the left and right, which is the rear drive pulley 50, as shown in Figure 2 is a belt wound on one idle pulley 53 ( The upper portion of the 55 is entered into the lower end of the driving pulley 50 is connected to the driving pulley 50 by one round to the opposite idle pulley 54 and then to the idle pulley 53 again. And the front drive pulley 40 is the upper portion of the belt 45 wound on one side idle pulley 43 enters the upper end of the drive pulley 40 to turn the drive pulley 40 one round to the opposite idle pulley 44 Connected to the idle pulley 43 again. The belts 45 and 55 are preferably belts having a circular cross section so as to have a predetermined tension when they are engaged. And the lower portion of each belt (45, 55) (belt portion located between the lower end of the idle pulley) is fixed to the upper part of the window and the rear belt 55 is coupled to the upper end of the left window (58) The front belt 45 is coupled to the right window 48.

Reference numerals 49 and 59 are belt fixing brackets.

The present invention having such a configuration can be operated in three modes.

When opening and closing the first left window 58; When the shift rod 90 moves forward by the operation of the front solenoid 80 dedicated switch, the shift lever 100 rotates about the hinge 102 by the connecting pin 92 so that the other end of the sleeve 35 is rotated. Is pushed backward so that the front side gear part 35b of the sleeve 35 is released from the connecting gear 42 of the driving pulley 40 and released, and the rear side gear part 35b is the connecting gear 52 of the driving pulley 50. ) Is matched with).

Therefore, the power transmission of the rotating shaft 20 and the front drive pulley 40 is blocked and the power transmission is possible only to the rear drive pulley 50.

In this state, when the driving motor 10 is rotated counterclockwise on the drawing of FIG. 2, the rotating shaft 20 rotates clockwise, and the rotation of the rotating shaft 20 rotates the rear drive pulley 50 clockwise. Let's go. At this time, the front drive pulley 40 is coupled to the rotating shaft 20 and the bearing 41, and is supported by the coupling force of the belt 45 and the right window 48, so as not to transmit the driving force to the drive pulley 40. The upper portion of the belt 55 moves from the right side to the left side and the lower side moves from the left side to the right side by the rotation of the rear drive pulley 50. The left side window 58 fixed to the bottom of the belt 55 moves to the right side. Open.

Meanwhile, when closing the left window, the driving motor 10 may be reversely rotated and the left window may be moved in the reverse direction of the operation. When the solenoid 80 switch is turned off, the sleeve 35 returns to the neutral position because the shift rod 90 is returned to its original position by the return spring 82.

When opening and closing the second right window 48; When the shift rod 90 is moved backward by the operation of the dedicated switch for the rear solenoid 70, the shift lever 100 is rotated about the hinge 102 by the connecting pin 92 so that the other end of the sleeve 35 is rotated. Will be pushed forward. Therefore, the power transmission of the rotating shaft and the rear drive pulley 50 is cut off and the power can be transmitted only to the front drive pulley 40. In this state, when the driving motor 10 is rotated counterclockwise on the drawing of FIG. 2, the rotating shaft 20 rotates clockwise, and the rotation of the rotating shaft 20 rotates the front drive pulley 40 clockwise. Let's go. At this time, the rear drive pulley 50 is coupled to the rotary shaft 20 and the bearing 51 to block the transmission of the rotation of the rotary shaft 20. The upper portion of the belt 45 moves from the left to the right and the lower portion moves from the right to the left by the rotation of the front drive pulley 40 so that the right window 48 fixed to the lower end of the belt 45 is moved to the left. Open. On the other hand, when the right window is closed, the drive motor 10 is reversely rotated and the right window is moved in the reverse direction of the operation. When the solenoid 70 dedicated switch is turned off, the sleeve 35 returns to the neutral position because the shift rod 90 returns to its original position by the return spring 72.

Third, simultaneous opening and closing of both windows; When the solenoids 70 and 80 are left in a neutral state in which they are not operated, the sleeve 35 is simultaneously connected to the front and rear drive pulleys 40 and 50.

In this state, when the driving motor 10 rotates counterclockwise, the rotation shaft 20 rotates clockwise. Therefore, when the left and right windows are opened and closed, the same operation as the detailed description is performed simultaneously. That is, the left window is moved to the right, the right window is moved to the left to open the window and the window can be closed by the reverse rotation of the drive motor 10.

As described above, the automatic window opening and closing device according to the present invention selectively transfers the power transmitted from the driving motor to either one of the rear driving pulley and the front pulley to allow the window to be piggybacked in the traveling direction of the belt wound around the selected driving pulley. As well as selectively opening and closing only one side of the window, it is possible to open and close both windows at the same time by transmitting power simultaneously to both windows, the user has the effect of selectively opening and closing the window according to the installation state or opening and closing situation of the windows. do.
