Problems solved by technology
This type of semi-automatic sunshade usually has the following problems: the sunshade is easy to rebound after a long time of use, it is easy to shake, wrinkle, or collapse when the sunshade is opened, and then forms a gap for light leakage on the side of the sunshade, and it is easy to produce jitter and vibration when it is rolled up. noise
[0004] At the same time, as the panoramic sunroof becomes more and more popular, due to the large area of the panoramic sunroof, it is impractical to manually open the sunshade of the panoramic sunroof

The invention relates to an automobile sunroof sun-shading curtain drive system. The automobile sunroof sun-shading curtain silent drive system comprises a two-way motor connected with a first flexible shaft and a second flexible shaft and driving the first flexible shaft and the second flexible shaft to synchronously rotate; thread teeth are arranged on the periphery of the first flexible shaft and on the periphery of the second flexible shaft; the first flexible shaft and the second flexible shaft are located on the two sides of a sun-shading curtain; the two flexible shafts are sleeved withsliding blocks; the two sliding blocks are provided with threaded sleeves matched with the flexible shafts; the two sliding blocks are connected with two guide rails, and the extension direction of the two guide rails is the same as the stretching direction of the sun-shading curtain; and the two sliding blocks are connected with the two ends of a cross bar of the sun-shading curtain. The unfolding and folding process of the sun-shading curtain is controlled stably, the sun-shading curtain does not shake in the unfolding and folding process, the sun-shading curtain is unlikely to deform, andgenerated noise is extremely small. The automobile sunroof sun-shading curtain silent drive system is stable in structure, simple in construction and easy to machine and assemble, and the number of parts in an automobile is reduced.
Description
technical field [0001] The invention relates to auto parts, in particular to an automobile sunroof sunshade driving system. Background technique [0002] The car sunroof is located on the roof of the car, and a sunshade is usually installed for the car sunroof. When the sun is strong, the car sunroof sunshade can block the light of the roof for the driver to ensure the comfort of the car environment. [0003] The sunshades of ordinary cars are mostly semi-automatic. When in use, the sunshades are pulled out by hand. When being recovered, the inner tube connected to the sunshade is driven by the winding motor to rotate so that the sunshade is rolled up. This type of semi-automatic sunshade usually has the following problems: the sunshade is easy to rebound after a long time of use, and it is easy to sway and wrinkle or collapse when the sunshade is opened, thereby forming a gap for light leakage on the side of the sunshade, and it is easy to produce vibration and vibration w...
