As shown in FIG. 7A, in the connected state of the intermittent mechanism 5, the plurality of spheres 51 are held at the first position by the plurality of shaft portions 522 of the cover plate 52.

In the connected state of the intermittent mechanism 5, the cover 53 has the flat surface 532 b of the flange portion 532 in contact with a part of the lower surface 563 b of the plate portion 563 of the slide lever 56. Thereby, the movement of the cover 53 and the cover plate 52 in the direction away from the drum 22 in the axial direction by the elastic force of the coil spring 55 is restricted.

When the solenoid unit 571 in the slide mechanism 57 of the intermittent mechanism 5 is energized from the control unit 4, the first and second rods 573 and 574 (shown in FIG. 2) of the slide mechanism 57 are both solenoids, as shown in FIG. 7B. While being sucked to the portion 571 (shown in FIG. 3), the slide lever 56 moves to the solenoid portion 571 side. Then, the cover plate 52 and the cover 53 are pushed up in the direction away from the drum 22 in the axial direction by the elastic force of the coil spring 55 and stopped at a predetermined position. Thereby, the movement to the outer side of the radial direction of the spherical body 51 of the cover plate 52 is cancelled | released.

Then, the sphere 51 is pressed from the second side surface 230 c of the recess 230 in the pinion 23, and the sphere 51 moves away from the recess 230 and moves to the accommodating portion 221 side (outside in the radial direction of the drum 22) of the drum 22. Thereby, the sphere 51 moves from the first position to the second position.

7B, the cover 53 engages with the inner edge of the through hole 563a of the slide lever 56, and the cover plate 52 is held at a predetermined position in the axial direction. Thereby, the spherical body 51 is held at the second position in a state in which the spherical body 51 is in contact with the wall surface 221c of the housing portion 221 in the drum 22. Thus, in the present embodiment, when the interrupting mechanism 5 switches from the connected state to the disconnected state, the second position from the first position of the sphere 51 that receives the rotational force of the pinion 23 in addition to the elastic force of the coil spring 55 is second. The cover plate 52 is configured to be pushed up in the axial direction stepwise by receiving the jumping force to the position with the plurality of shaft portions 522 of the cover plate 52.

In a state where the sphere 51 is held at the second position, the sphere 51 is out of the power transmission path between the drum 22 and the pinion 23, so that the drum 22 and the pinion 23 can be rotated relative to each other. In other words, the drum 22 and the pinion 23 are disconnected from each other.

Thus, in this embodiment, the spherical body 51 as a power transmission member is moved from the first position to the second position by using the rotational force of the pinion 23, so that the power transmission between the drum 22 and the pinion 23 is performed. It is possible to shut off instantaneously.

On the other hand, when the interrupting mechanism 5 is switched from the cut-off state to the connected state, current is supplied from the control unit 4 to the electric motor 21 and current is also supplied to the solenoid unit 571 of the slide mechanism 57, so that the slide lever 56 moves away from the solenoid portion 571 (from the position shown in FIG. 7B to the position shown in FIG. 7A). At that time, the inner edge of the through hole 563 a of the slide lever 56 slides on the inclined surface 532 a, and the cover plate 52 and the cover 53 are pushed down in the direction approaching the axial drum 22.

Then, the sphere 51 is pressed by the tip portions of the plurality of shaft portions 522 of the cover plate 52 and moves inward in the radial direction of the drum 22 (from the second position to the first position). The lower surface 563b of the plate portion 563 of the slide lever 56 contacts the flat surface 532b of the cover 53, and the sphere 51 is held at the first position by the shaft portion 522 of the cover plate 52. As a result, the drum 22 and the pinion 23 are connected to each other so as to be integrally rotatable.

Next, the control method of the control unit 4 when the vehicle is submerged and the operation of the window glass 9 by this control method will be described with reference to FIGS. 8 to 10B. FIG. 8 is a flowchart illustrating an example of processing executed by the CPU as the control unit 4. FIG. 9A is an explanatory diagram showing a state of the window glass 9 before the window glass 9 is fully closed and before the moving means 43 of the control unit 4 is operated. FIG. 9B is an explanatory view showing a state in which the window glass is lowered from the position of FIG. 9A by operating the moving means. FIG. 10A is an explanatory diagram showing the state of the window glass 9 before the window glass 9 is in a non-fully closed state and before the moving means 43 of the control unit 4 is operated. FIG. 10B is an explanatory view showing a state in which the window means 9 is lifted from the position of FIG. 10A by operating the moving means 43.

As shown in FIG. 8, first, the abnormality detection means 41 determines whether or not the vehicle has been submerged (step S1). If it is not determined that the vehicle is submerged (step S1: No), the process of step S1 is repeated. On the other hand, if it is determined in step S1 that the vehicle is submerged (step S1: Yes), the position detector 42 determines whether the window glass 9 is at a predetermined position (step S1). S2).

Here, the predetermined position is a position where the window glass 9 is lowered from the fully closed state so that at least an occupant can put his / her finger on the upper end of the window glass 9 and a sudden increase in water immersion speed when the vehicle is submerged. This is the position where the window glass 9 is closed to the extent necessary to prevent it. In this embodiment, it set so that the length (L shown to FIG. 9B and 10B) in the raising / lowering direction of the window glass 9 in the opening part of the door frame window glass 9 might be set to 20 mm.

In the process of step S2, when it is not determined that the window glass 9 is in the predetermined position (step S2: No), the control unit 4 executes the position detecting unit 42 after executing the moving unit 43. It is determined whether or not the window glass 9 is at a predetermined position (step S4). In the process of step S4, when it is not determined that the window glass 9 is in the predetermined position (step S4: No), the control unit 4 executes the moving unit 43 again. On the other hand, when it determines with the window glass 9 being in a predetermined position in the process of step 4, (step S4: Yes), the control part 4 performs the interruption | blocking execution means 44 (step S5), and the intermittent mechanism A command current value is supplied to the slide mechanism 57 so that 5 is cut off. That is, the control unit 4 is configured to repeatedly execute the processes of step S3 and step S4 in which the window glass 9 moves to a predetermined position. On the other hand, if it is determined in step S2 that the window glass 9 is in a predetermined position (step S2: Yes), the control unit 4 executes the blocking execution means 44 (step S5), and FIG. The process of the flowchart shown in FIG.

In the process of step S2 described above, for example, when the window glass 9 is in the fully closed state shown in FIG. 9A, the control unit 4 executes the moving means 43, so the window glass 9 starts to descend in the direction of the arrow. And the control part 4 repeats the process of step S3 and step S4, and the window glass 9 stops in a predetermined position (FIG. 9B). Thereafter, the intermittent mechanism 5 enters a shut-off state by executing the process of step S5 of the control unit 4. As a result, power transmission between the pinion 23 and the drum 22 is interrupted, so that the passenger can put his / her finger into the opening of the window frame and manually lower the window glass 9. In the present embodiment, the window glass 9 is not lowered by its own weight due to the sliding resistance with the weather strip provided on the window frame when the interrupting mechanism 5 is cut off.

Further, for example, when the window glass 9 is positioned below a predetermined position as shown in FIG. 10A when the vehicle is submerged, the window glass 9 starts to rise in the direction of the arrow and moves to the predetermined position. By the way, it is controlled to stop (see FIG. 10B). In this case as well, as described with reference to FIGS. 9A to 9B, after the window glass 9 stops at a predetermined position, the interrupting mechanism 5 enters the shut-off state by executing the process of step S5 of the control unit 4. A passenger can manually lower the window glass 9.

According to the present embodiment described above, the following operations and effects can be obtained.

(1) The vehicle window glass opening and closing device 100 includes an interrupting mechanism 5 that interrupts power transmission between the pinion 23 connected to the electric motor 21 side and the drum 22 connected to the carrier plate 32 and the wire 33. The control unit 4 has moving means 43 that automatically moves the window glass 9 to a predetermined position when the vehicle is submerged. Thus, the passenger can directly lower the window glass 9 manually without performing an operation such as operating a release lever as in the apparatus described in Patent Document 1, for example. Furthermore, since the window glass 9 does not fully open unlike the device described in Patent Document 2, it is possible to prevent the water immersion rate into the vehicle compartment from rapidly increasing when the vehicle is submerged. That is, it is possible to ensure a safe and reliable exit for the occupant in an emergency such as when the vehicle is submerged.

(2) Since the control unit 4 includes the position detection means 42, the window glass 9 is automatically placed at a predetermined position regardless of the position of the window glass 9 when the abnormality detection means 41 detects an abnormality of the vehicle. Can be moved.

(3) By moving the window glass 9 to a predetermined position (opening 20 mm in the present embodiment), it is possible to intuitively notify the occupant that the window is open when the vehicle is submerged. That is, even if the occupant falls into a panic state, it can be intuitively guided to the exit.

When the vehicle condition is abnormal, for example, when the vehicle falls over the land, the window glass 9 automatically moves to a predetermined position, thereby preventing the passenger from being thrown out of the vehicle and ensuring safety. It is possible. In addition, the passenger can be rescued outside the passenger compartment without breaking the window glass 9.

As mentioned above, although this invention was demonstrated based on embodiment, embodiment described above does not limit the invention which concerns on a claim. In addition, it should be noted that not all combinations of features described in the embodiments are necessarily essential to the means for solving the problems of the invention. Further, the present invention can be appropriately modified and implemented without departing from the spirit of the present invention.

For example, after the control unit 4 executes the abnormality detection unit 41, it may be controlled so that the seat belt is released automatically by giving a voice instruction to the occupant. Thereby, a passenger's panic state can be relieved and a passenger | crew's safety can be ensured more reliably.

In the above embodiment, the vehicle window glass opening and closing device according to the present invention is described as a representative example in which it is a so-called power window that automatically raises and lowers the window glass provided on the door of the vehicle. Although only the case where the interrupting mechanism 5 is applied to the drive unit 2 of the opening / closing device 100 has been described, the use of the interrupting mechanism 5 is not limited to this, and the opening / closing body with respect to the opening formed in the automobile is defined as the open position. Any device provided with a drive mechanism that moves between the closed position and the closed position can be applied. For example, the intermittent mechanism according to each embodiment described above can be applied to a drive mechanism for a sunroof, a power back door, or a slide door of an automobile.
