BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0018]
FIG. 1 is a view showing a door window with a sunshade according to the present embodiment, and shows an example in which the present invention is applied to a door for getting on and off a passenger car. In the door window with a shade shown in FIG. 1, a window glass 12 whose lower end is supported by a frame member 10 is provided so as to close a window formed by a window frame 16 of a door member 14. An elevating arm 18 connected to the frame member 10 is driven up and down by a window elevating motor 20, and the window glass 12 is driven up and down by the window elevating motor 20 so as to close the window or to open the window. Is driven downward.
[0019]
Further, the window glass 12 is provided with a shade member 22 formed in a curtain shape so as to cover the inside of the window glass 12, and is wound by a storage member 24 fixed to the frame member 10. It is stored.
[0020]
FIG. 2 is a perspective view showing the storage member 24 provided on the frame member 10. The storage member 24 shown in FIG. 3 is provided below the window glass 12 and on the vehicle interior side, and winds and stores the sunshade member 22 by a core member 26 (see FIG. 3) provided with a winding drive means. The sunshade member 22 can be driven so as to cover the inside surface of the vehicle.
[0021]
FIG. 3 is a view showing the core member 26 incorporated in the storage member 24. As shown in FIG. The stator member 30 of the ultrasonic motor is provided on the core member 26 shown in FIG. The stator section 30 can generate vibration on a contact surface with the winding section 28, and the vibration can rotate the winding section 28 of the core member 26 in the forward and reverse directions. As the ultrasonic motor used here, one described in JP-A-6-38557 is exemplified.
[0022]
The stator part of the ultrasonic motor can be classified into a two-way rotation type in which the rotor can be rotated in the forward and reverse directions, and a one-way rotation type in which the rotor can be rotated in either the forward or reverse direction. Any type of stator may be used. When a one-way rotation type is used, it is preferable to separately provide a winding device or a sending device of the sunshade member 22 using a spring or the like as a means for rotating in the other direction. As described above, by using the stator unit 30 of the ultrasonic motor as a driving device for winding or sending out the sunshade member 22, a higher output can be used as compared with a normal electromagnetic motor, and at the time of operation. , The occurrence of motor noise can be suppressed.
[0023]
By the way, in the door window with the sunshade, the core member 26 is attached to the frame member 10 side. With this configuration, when the window glass 12 is driven to descend, the sunshade member 22 descends following the window glass 12. In this way, even if the window glass 12 is driven downward, it is not positioned below the awning member 22 and the awning member 22 is not directly exposed to the outside air. Therefore, the awning member 22 can be prevented from being damaged or stained.
[0024]
In addition, instead of the core member 26, a core member 38 in which stator portions 32 and 34 of two ultrasonic motors are provided in pressure contact with both end surfaces of the winding portion 36 as shown in FIG. In this way, when a one-way rotation type ultrasonic motor is used, one can be used for winding and the other can be used for sending. In addition, when a bidirectional rotation type ultrasonic motor is used, a higher output can be obtained by driving and using both the stator units 32 and 34 at the time of winding driving or sending driving.
[0025]
In the above description, the stator unit of the ultrasonic motor is used as a driving unit for winding or sending, but an electromagnetic motor may be used. Further, it is not always necessary to wind up the awning member 22 when storing the awning member 22, and the awning member 22 may be stored by the same translation drive as the window glass 12 (see FIG. 5).
[0026]
Next, control means of the sunshade-attached door window will be described. FIG. 5 is a diagram illustrating a configuration of a control unit of the door window with the sunshade.
[0027]
The window window with a shade shown in FIG. 1 is raised by a window raising / lowering motor 20 so that the window glass 12 covers the window of the door member 14, or is lowered so as to open the window. Further, a window glass position sensor 40 is attached, and the position of the window glass 12 is detected by detecting the rotation speed of the window lifting motor 20. Similarly, the awning member 22 is raised by the awning member elevating motor 42 so as to cover the window glass 12, or is lowered from a position covering the window glass 12. Further, a sunshade member position sensor 44 is attached, and the position of the sunshade member 22 is detected by detecting the rotation speed of the sunshade member elevating motor 42.
[0028]
Further, the door window with sunshade is provided with a solar radiation sensor 46 above the window frame portion 16 so that it is possible to determine whether or not to use the sunshade member 22 based on the amount of light such as sunlight outside the vehicle.
[0029]
The control circuit 48 controls the window glass 12 elevating motor in accordance with the states of the window glass elevating switch 50, the awning member elevating switch 52, the window glass position sensor 40, the awning member position sensor 44, the insolation sensor 46, and the insolation sensor switch 54. 20 and the supply of electric power to the sunshade member elevating motor 42 is controlled.
[0030]
Next, the operation of the above-described door window with awning will be described. FIG. 6 is a flowchart for explaining the operation of the sunshade member elevating motor 42 of the door window with sunshade. In the door window with the sunshade, when the user sets the sunshade member elevating switch 52 to the "shade member up" state (STEP 1), the control circuit 48 activates the sunshade member elevating motor 42 to drive the sunshade member 22 up. (STEP 2). Then, the position of the sunshade member 22 indicated by the sunshade member position sensor 44 and the position of the window glass 12 indicated by the window glass position sensor 40 coincide with each other, and the sunshade member 22 has risen to a position covering the window glass 12 as necessary and sufficient. If so (STEP 3), the control circuit 48 stops supplying power to the awning member elevating motor 42 (STEP 4).
[0031]
When the sunshade member elevating switch 52 is set to the "shade member lowering" state (STEP 1), the control circuit 48 activates the sunshade member elevating motor 42 to drive the sunshade member 22 down (STEP 5). If the sunshade member position sensor 44 detects that the sunshade member 22 is completely stored (STEP 6), the control circuit 48 stops supplying power to the sunshade member elevating motor 42 (STEP 4).
[0032]
According to the control described above, when the awning member 22 is driven to move upward, the awning member 22 does not rise beyond the uppermost end of the window glass 12. In this case, the awning member 22 is not directly exposed to the outside air, and the damage and dirt can be suppressed.
[0033]
FIG. 7 is a flowchart illustrating the operation of the window elevating motor 20 of the door window with the sunshade. When the user sets the window glass raising / lowering switch 50 to the "window glass raising" state in the door window with the sunshade (STEP 101), the control circuit 48 activates the window raising / lowering motor 20 to drive the window glass 12 upward (step 101). (STEP 102). When the window glass position sensor 40 detects that the window glass 12 has risen to the uppermost position (STEP 103), the control circuit 48 stops supplying power to the window elevating motor 20 (STEP 104).
[0034]
When the window glass raising / lowering switch 50 is set to the "window glass lowering" state (STEP 101), the control circuit 48 activates the window raising / lowering motor 20 to lower the window glass 12 (STEP 105). If the position of the window glass 12 indicated by the window glass position sensor 40 matches the position of the sunshade member 22 indicated by the sunshade member position sensor 44 (STEP 106), the control circuit 48 further controls the sunshade member elevating motor 42. When activated, the awning member 22 is driven downward by following the window glass 12 (STEP 107). When the window glass position sensor 40 detects that the window glass 12 has been lowered to the lowermost end (STEP 108), the awning member elevating motor 42 is stopped (STEP 109), and the window glass 12 elevating motor 20 is stopped. (STEP 104).
[0035]
According to the control described above, when the window glass 12 is driven downward, it is not driven downward beyond the uppermost end of the sunshade member 22, and the sunshade member 22 is not directly exposed to the outside air. Can be suppressed. Furthermore, since the sunshade member 22 can move down following the window glass 12, the window glass 12 can be completely opened without exposing the sunshade member 22 to the outside air.
[0036]
In the description of each operation, the solar radiation sensor switch 54 is turned off and the solar radiation sensor 46 is not used. When using the solar radiation sensor 46 of the door window with the sunshade, the solar radiation sensor switch 54 is turned on. The solar radiation sensor 46 determines whether the sunshade member 22 is necessary based on the amount of light outside the vehicle. When the sunshade sensor 46 determines that the sunshade member 22 is necessary, the sunshade member 22 is driven upward by performing the same control as the control described with reference to FIG. When it is determined that the sunshade member 22 is unnecessary, the same control as that described with reference to FIG. 6 is performed to drive the sunshade member 22 downward. In this way, the sunshade member 22 can be automatically moved up and down according to the amount of light outside the vehicle without the driver instructing the sunshade member 22 to go up and down by the sunshade member elevating switch 52.
[0037]
Further, the mode of the sunshade member elevating motor 42 is not limited to the above-described one, and various modifications are possible.
