In the present embodiment, the motor 32 is an automatic motor, such as an EY25 remote control motor. The motor 32 of the present invention can be controlled by a remote control, and the same remote control can control multiple motors 32 simultaneously. The remote controller of the present invention can control 15 motors 32 at the same time. The stroke of each motor 32 may be different or the same, and the motor 32 may stop at any point in the stroke. The model of the remote controller is BF315 or BF 515.

In the present embodiment, the window covering device 100 is mainly applied to an automobile. Of course, the window covering device 100 of the present invention may also be applied to a building, such as an office or a home.

When the curtain folding device is used, if the curtain 61 needs to be unfolded, the motor 32 is controlled to move through the remote controller, so that the rotating structure 50 and the curtain mounting shaft 62 are controlled to rotate along the first direction or the rotating structure 50 is controlled to rotate along the first direction, and the curtain 61 mounted on the curtain mounting shaft 62 is unfolded; if the curtain 61 needs to be closed, the motor 32 is controlled to move by the remote controller, so as to control the rotating structure 50 and the curtain mounting shaft 62 to rotate in the second direction or control the rotating structure 50 to rotate in the second direction, and the curtain 61 mounted on the curtain mounting shaft 62 is closed. The first direction and the second direction are opposite, for example, the first direction is a clockwise direction, and the second direction is a counterclockwise direction.

The curtain 61 is controlled by the motor 32, so that the curtain 61 is automatically folded or unfolded, and the problem that the curtain is inconvenient because of manual operation in the prior art is solved. Further, when the curtain device 100 of the present invention is installed in a vehicle, the curtain 61 can be controlled to be unfolded or folded by a remote controller even if there is no person in the vehicle, and thus the use is very convenient. Or, before leaving the car, forget to open or close the window covering 61, or open or close the window covering 61 by a remote controller. Further, because the curtain 61 of the invention is controlled by the motor 32, a driver can control the curtain 61 of the whole vehicle, the curtain 61 cannot be unfolded or folded because the backseat is unmanned, and the convenience of use is greatly improved.

In this embodiment, two motors 32 are respectively installed at both ends of the third side 230 of the window frame 200, that is, one motor 32 controls the opening or closing of one side of the window covering 61. When the window shade device 100 is used, a user can freely change the shape of the window shade 61 according to the shape or the requirement of the window frame 200, for example, the window shade 61 on the first side 210 of the window frame 200 runs for a distance of 0.5m, while the window shade 61 on the second side 220 of the window frame 200 is stationary, so that the window shade 61 is a triangle, and the window shade device 100 with two motors 32 can be used for window frames 200 with various shapes, and can meet the individual requirements of the user. In other words, the two motors 32 can be simultaneously started to enable the curtains 61 to run in parallel, or each motor 32 can be independently started to realize the respective fan-shaped swinging and rotating operation of the left side and the right side.

In other embodiments, there is one motor 32. The window covering apparatus 100 having only one motor 32 is applicable to the window frame 200 in which the lengths of the first side 210 and the second side 220 of the window frame 200 are not greatly different.
