detailed description

As shown in FIGS. 1-3 , the sunroof for a caravan involved in the present invention mainly includes: a daylighting cover 1 , an outer frame 2 , an inner frame 3 , a flexible shaft drive system, and a fixing member.

The daylighting cover 1 is on the outer frame 2, and is connected with the outer frame 1 through a hinge and a support rod. One end of the support rod is connected with the flexible shaft inside the outer frame 2, and can slide horizontally in the flexible shaft guide rail. The outer frame 2 is fixed to the walls around the opening on the top of the caravan through the fixing piece. The inner frame 3 is fixed to the inner surface of the top wall of the caravan through a fixing piece. The flexible shaft driving system runs through the lighting cover 1, the outer frame 2, and the inner frame 3, so as to realize functions such as controlling the opening and closing of the lighting cover inside the caravan.

The daylighting cover 1 is made of transparent organic material, the middle part is a double-layer hollow structure, and the surrounding part is a single-layer structure; when the daylighting cover 1 is completely closed, it is automatically locked with the outer frame 2 by the locking hook, and the daylighting cover cannot be opened from the outside.

As shown in Fig. 3, the fixed part is divided into a fixed part I4 and a fixed part II6, the fixed part I has an inner cavity structure with a shrinking opening and a wing structure outside the inner cavity, and the upper part of the fixed part II6 is stuck on the fixed part 4I At the retractable opening, the lower part is connected to the inner frame with screw I7; the wing part of the fixing part 4I is fixed to the outer frame with screw II8.

The outer frame 2 is made of organic materials, and is the main part of the sunroof for the caravan. Other parts of the skylight for the caravan are connected with the outer frame. The edge of the layer forms a U-shaped labyrinth seal, thereby reducing the speed of the wind entering the interior of the car from the skylight, and filtering out some dust and water droplets in the air. Filter cotton strips can be installed in the U-shaped structure to enhance the filtration of the U-shaped labyrinth seal function, and a sealing strip can also be installed to realize the complete sealing of the sunroof for the caravan.

The inner frame 3 has a sunshade curtain and a gauze curtain. The sunshade curtain and the gauze curtain are 100-fold structures, one end of which is fixed on both sides of the inner frame 3, and one end is connected with a pull rod. Plugs are installed at both ends of the pull rod, and the pull rod slides horizontally in its guide rail. Open or close the sunshade or screen curtain. There are two pull ropes inside the pull rod. The two ends of the pull rope are fixed on the inner frame. The friction generated by the contact between the pull rope and the pull rod plug makes the pull rod parallel to one side of the inner frame. , and it is not easy to slide by itself in its guide rail, so as to ensure that the position of the tie rod is fixed when the vehicle is running.

The flexible shaft drive system uses a hand crank or a motor as the power source to drive the gears in the gear box to rotate. The output gear of the gear box drives the flexible shaft that meshes with it to slide in both directions. The sliding of the flexible shaft drives one end of the support rod to move It moves horizontally in the guide rail, so that the supporting rod rotates relative to the daylighting cover, and the daylighting cover is pulled to close or pushed to open.

The sunroof for a caravan involved in the utility model has the functions of lighting, shading, heat preservation, ventilation, ventilation, mosquito prevention, etc., and has a reasonable structure, convenient use, beautiful appearance, and the cost is far lower than similar foreign products.

The specific implementation described in the utility model does not constitute a limitation to the scope of the application, and within the spirit and principles of the utility model, any amendments, equivalent replacements and improvements that professionals in the field can make should include Within the protection scope of the present utility model.
