[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments may be combined with each other.

[0020] The following further illustrates the present invention with reference to the accompanying drawings and specific embodiments, but is not a limitation of the present invention.

[0021] The sunshade system for windows provided in the present invention, refer to Figure 1 and Figure 2, including a frame body 1, a rotating shaft 2, a sunshade cloth 4, a curve fitting chain 5, a vertical slide rail 11 and a vertical telescopic rod 6. The frame body 1 can be installed at an appropriate position on the windows of buildings, high-speed rails, passenger cars, etc. Then, both ends of the rotating shaft 2 are rotatably connected to the upper end of the frame body 1, and the sunshade cloth 4 is wound around the outer periphery of the rotating shaft 2. A vertical slide rail 11 is arranged vertically on the inner side of the frame body 1. The curve fitting chain 5 is arranged inside the frame body 1. The curve fitting chain 5 is fixedly connected to the lower end of the sunshade cloth 4, and both ends of the curve fitting chain 5 are slidably connected inside the vertical slide rail 11. One end of the vertical telescopic rod 6 is connected to the frame body 1, and the other end of the vertical telescopic rod 6 is connected to the curve fitting chain 5.

[0022] And in this embodiment, the vertical telescopic rod 6 can adopt a telescopic rod that can be automatically limited. For example, the vertical telescopic rod 6 includes multiple mutually sleeved serrated rods, such as Figure 3 the first section 61 of the vertical telescopic rod, the second section 62 of the vertical telescopic rod, and the third section 63 of the vertical telescopic rod shown, or an electric telescopic rod, etc.

[0023] On the large windows of high-rise office buildings or on public buses and high-speed rails, when multiple rows of colleagues in the office share a window or multiple rows of passengers on the high-speed rail share a window, some people on the same window need to cover the window with the sunshade cloth 4 to block sunlight, while some people want to pull back the sunshade cloth to enjoy the scenery. In this case, in the present invention, one or more vertical telescopic rods 6 can be driven to expand and contract, so as to buffer the free end of the sunshade cloth 4 by using the wavy structure at the lower end of the curve fitting chain 5, and adjust the area of the sunshade cloth 4 covering the window glass. Furthermore, different users can adjust the area of the sunshade cloth 4 on the same window according to their own needs and the change of external light, meeting the different sunshade requirements of the crowd for the same window in a public environment, and effectively solving the problem that the traditional sunshade system can only achieve overall full sunshade or no sunshade state.

[0024] Two hairspring springs 3 are arranged on both sides of the sunshade cloth 4. The hairspring springs 3 are wound around the rotating shaft 2. When the vertical telescopic rod 6 is pushed upward, the retracted sunshade cloth 4 can be automatically wound back onto the rotating shaft 2 for storage.

[0025] In addition, referring to Figure 1 , a horizontal slide rail 12 is also arranged on the inner side of the frame body 1, and a sliding track 51 is also arranged on the curve fitting chain 5. One end of the vertical telescopic rod 6 is slidably connected inside the horizontal slide rail 12, and the other end of the vertical telescopic rod 6 is slidably connected inside the sliding track 51, which can enable the vertical telescopic rod 6 to slide along the length direction of the horizontal slide rail 12, so as to realize the adjustment of the sunshade position by the demanders at different positions close to the window.

[0026] Among them, the vertical telescopic rod 6 is perpendicularly arranged with the horizontal slide rail 12, which can enable the vertical telescopic rod 6 to stably slide inside the horizontal slide rail 12.

[0027] Referring to Figure 1 , an inclined telescopic rod 7 is disposed obliquely between two adjacent vertical telescopic rods 6, and one end of the inclined telescopic rod 7 is rotatably connected to the end of a vertical telescopic rod 6, and the other end of the inclined telescopic rod 7 is also rotatably connected to the end of the other vertical telescopic rod 6. The provided inclined telescopic rod 7 can not only support two adjacent vertical telescopic rods 6, but also maintain the overall stability.

[0028] In addition, the end of the vertical telescopic rod 6 is a spherical member 8, which is convenient for the vertical telescopic rod 6 to slide in the horizontal slide rail 12 and the sliding track 51.

[0029] The implementation principle of the sunshade system for windows provided in the present invention: When the user needs to adjust the area of the sunshade cloth 4 on the same window according to his own needs and the external light change, he can first drive the vertical telescopic rod 6 to slide along the direction of the horizontal slide rail 12. After the vertical telescopic rod 6 slides to an appropriate position, then drive the vertical telescopic rod 6 to adjust to an appropriate position in the vertical direction, and the adjustment of different sunshade areas at different positions on the same window can be realized.

[0030] The above are only the preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention. For those skilled in the art, it should be realized that all the equivalent replacements and obvious changes made by using the description and illustrations of the present invention should be included in the protection scope of the present invention.
