Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, a top vent valve of a passenger car includes a guide rail 1 connected to a roof and having a concave shape, guide plates 2 located below two sides of the guide rail 1, a cover plate 3 matching with a roof vent, and a cylinder 4 driving the cover plate 3 to open or close; sliding plates 5 are tightly attached to two opposite sides of the guide rail 1, two ends of each sliding plate 5 are connected with a connecting rod 6 and a pulley I7 through a rotating shaft, and the pulley I7 is positioned in the guide rail 1 and can slide along the guide rail; a notch 8 is formed in the position, close to the vent, of the guide plate 2, shaft sleeves 9 are connected to four corners of the cover plate 3, the lower ends of the connecting rods 6 are connected with the shaft sleeves 9 through rotating shafts, the lower ends of the two connecting rods 6, close to one side of the guide plate 2, are also connected with a second pulley 10 through rotating shafts, and the second pulley 10 can slide along the top of the guide plate 2 and can slide into the notch 8; a cross rod 11 is connected between the two sliding plates 5, the telescopic end of the cylinder 4 is connected with the cross rod 11, and the other end of the cylinder 4 is connected with the bottom of the guide rail 1.
Specifically, be equipped with the boss 12 that inwards extends in the vent, be equipped with the recess 13 that is the rectangle on the boss 12, be equipped with waterproof pad 14 in the recess 13, apron 3 downside is equipped with the chimb 15 that matches with recess 13.
