【Detailed ways】

The utility model has a sunshade with a guide rail, which is suitable for being installed on a car window of a car, and is used to prevent sunlight from irradiating into the car through a glass of the car window. The window can be a front window, a rear window, side windows on both sides or a sunroof.

As shown in Figure 1, the embodiment of the sunshade curtain with guide rail of the present invention includes a retracting device 1 and two which can be fixed on one side of the window (not shown), and are respectively fixed on two opposite sides of the window. A guide rail 2 on the side and perpendicular to the retracting device 1 , and a curtain device 3 retracted on the retracting device 1 .

The retracting device 1 includes two fixed seats 11 fixed at intervals on the vehicle window, a reel 12 pivotally mounted between the fixed seats 11 and storing retracting elastic force, and a reel 12 arranged between the fixed seats 11 and The casing 13 covers the outside of the reel 12 .

The casing 13 has an elongated notch 131 extending along its length, and cooperates with the reel 12 to define a retracting space 14 .

The opposite surfaces of the guide rails 2 respectively have a chute 21 extending along its length direction and have a dovetail-shaped cross-section, and one end of the guide rails 2 adjacent to the reel 12 has an opening 22 communicating with the chute 21 . The two sliding grooves 21 have a narrow groove portion 211 and a wide groove portion 212 extending along the lengthwise direction and communicating with each other. The narrow groove portions 211 of the two sliding grooves 21 are opposite to each other.

As shown in FIG. 2, the curtain device 3 includes a curtain 31 fixed on the reel 12 with one end, a pull rod 32 and a positioning member 33 arranged at the other end of the curtain 31, and several protruding from the The curtain 31 faces the sliders 34 on both sides of the two fixing seats 11 . The other end of the curtain 31 passes through the notch 131 of the casing 13 . The pull rod 32 is fixed at the end edge of the other end of the curtain 31 for pulling. The positioning member 33 has a flexible plate 331 protruding from the curtain 31 and a suction cup 332 disposed on the bottom surface of the plate 331 . Two opposite ends of the pull rod 32 are slidably inserted into the slide grooves 21 respectively. Each sliding member 34 has a linear narrowing section 341 extending from the curtain 31 and is a flexible material, and a relatively thick hard spherical sliding section 342 fixed on the outer edge of the narrowing section 341 .

The pull rod 32 can move relative to the retracting device 1 between a deployed position as shown in FIG. 1 and a retracted position as shown in FIG. 3 . When in the retracted position, the curtain 31 is retracted outside the reel 12, and the sliding parts 34 are distributed on the periphery of the reel 12 at intervals, and the pull rod 32 cannot pass through the gap of the housing 13. 131, while being blocked by the outer surface of the casing 13.

As shown in Figures 1, 4, and 5, when the pull rod 32 moves from the retracted position to the unfolded position, the pull rod 32 gradually moves away from the retracted device 2, and drives the curtain 31 from the retracted space 14 to the At this time, the sliding sections 342 of the sliding parts 34 on each side are embedded in the wide groove portion 212 of the chute 21 on the same side from the openings 22 of the guide rails 2 in sequence, and move away from the chute 21 along the direction in which the chute 21 extends.
