The guide opening is rotatably configured so that the angle between the line segment defined by the guide opening and the front positioning part 20 and the horizontal plane is adjustable. In this embodiment, the guide opening can guide the front curtain 2 that passes through it, so as to limit the tilt angle of the part of the front curtain 2 outside the guide opening. The component containing the guide opening is rotatably configured. By rotating the guide opening, the angle of the guide opening can be adjusted, thereby adjusting the tilt angle of the part of the front curtain 2 outside the guide opening, so as to adjust the distance between the front curtain 2 and the vehicle interior floor 11, achieving a balanced effect of blocking foreign objects 4 and utilizing space.

[0032] Optionally, the front bracket includes a first guide rod and a second guide rod disposed opposite to each other, defining a guide opening.
