Manual side window rolling curtain devices and electric side window rolling curtain devices each have their own advantages. Generally speaking, the rear side window of a motor vehicle is narrow at the top and wide at the bottom in accordance with the shape of the vehicle body, and because the area of ​​the rear side window is relatively large, a window pillar is usually set near the rear end of the rear side window to separate the rear side window into two parts, front and rear. As for the electric side window rolling curtain device, in order to match the shape of the rear side window, the curtain provided by the electric side window rolling curtain device must match the shape of the rear side window that is narrow at the top and wide at the bottom. At the same time, in order to ensure that the curtain of the electric side window rolling curtain device is sufficiently supported after being unfolded, most of the existing electric side window rolling curtain devices use two rods to support the unfolded curtain. The specific composition and structure of the existing electric side window rolling curtain device are described as follows.

During the process of the curtain strip 40 descending and driving the curtain 30 to retract, the auxiliary guide assembly 60 that moves downward along the guide column 13 uses its cross-rail slider 62 to laterally displace along the cross-slide portion 43 of the curtain strip 40 in the direction relative to the front of the motor vehicle, and produces lateral position compensation in accordance with the inclined guide column. On the other hand, the curtain strip 40 is movably connected to the base column slider 51 of the guide assembly 50 through the cross-strip end piece 42 that can be laterally extended and retracted in the connecting end 411 of the cross-strip body 41 of the curtain strip 40, so that during the process of the curtain strip 40 descending and laterally displacing in the direction relative to the front of the motor vehicle, lateral position compensation is also produced between the cross-strip body 41 and the guide assembly 50, and the distance between the connecting end 411 of the curtain strip 40 and the base column 12 is increased.

[0068] As can be seen from the above description, the side window rolling blind device of the present invention utilizes the side strip body of the curtain edge strip facing the side of the guide column to form a transverse slide rail portion protruding outward, and the auxiliary guide assembly that can move up and down along the guide column is connected to the transverse slide rail portion of the curtain edge strip by its transverse rail slider, and the transverse rail slider can slide laterally along the transverse slide rail portion, thereby, the auxiliary guide assembly connected to the curtain edge strip can not only move up and down along the guide column, but also utilizes the transverse position compensation structure formed by the auxiliary guide assembly and the transverse slide rail portion of the curtain edge strip, so that it can conform to the guide column set obliquely. Furthermore, by utilizing the position compensation structure between the auxiliary guide assembly and the transverse slide rail portion of the curtain edge strip to adopt an externally connected combined structure, the transverse rail slider can easily connect to the transverse slide rail portion, so that it has good assembly simplicity.

[0069] Furthermore, the present invention utilizes the connecting hook of the transverse rail slider to movably hook the lateral retaining edge of the transverse rail portion through the lower side rail portion, the side rail portion is located in the transverse guide groove between the limiting protrusion and the connecting hook, and the limiting protrusion is located above the side rail portion for limiting. Thus, the transverse rail slider can be smoothly connected to the transverse rail portion and can prevent the transverse rail slider from being separated from the transverse rail portion.
