Description

Automatic rolling device for automobile roof Technical Field The invention belongs to the technical field of automobile accessory instruments, and particularly relates to an automatic rolling device for an automobile roof. Background Along with the wide application of the automobile industry to intelligent and comfortable upgrading and the panoramic sky curtain of the new energy automobile, the sunshade curtain at the top of the automobile is a core interior decoration component for improving driving experience, and is mainly used for shielding direct sunlight at the top of the automobile, reducing the temperature in the automobile and blocking ultraviolet rays, guaranteeing the privacy of drivers and passengers and improving the comfort of a cabin. The automobile top sunshade curtain in the current market is mainly divided into two major types, namely manual type sunshade curtain and electric type sunshade curtain, and is widely applied to various passenger vehicles and commercial vehicles. Manual formula top sunshade screen simple structure, cost are lower, adopt the design of rolling up curtain formula more, and through artifical tractive curtain cloth and fixed with the help of the buckle, but its convenience of use is poor, driver and passengers complex operation, and long-term manual tractive easily leads to the curtain cloth to warp, the buckle wearing and tearing, can't realize a key control and with automobile body system linkage, be difficult to adapt to high-end motorcycle type and intelligent cabin demand. Although the electric top sunshade curtain solves the defect of manual operation, the curtain cloth is driven to open and close by a motor, so that one-key control is realized, but the electric top sunshade curtain has obvious defects that the structure is complex, a plurality of components such as a motor, a speed reducing mechanism and a sliding rail are required to be matched, the limited space inside a roof is easily occupied, the weight and the manufacturing cost of a vehicle are increased, the running stability is insufficient, the problems of clamping stagnation, abnormal sound and the like are easily caused, and the later maintenance difficulty is high. In addition, the existing sunshade curtain is used for heat insulation in a physical sun-proof mode through directly shielding a skylight, and can effectively isolate heat of the skylight, but light propagation is blocked, light in a vehicle cannot be regulated, and use requirements of different people cannot be met. In addition, the existing top sunshade curtain has the problems of poor light shielding and visual field balance, limited heat insulation effect and the like, and part of intelligent products can realize basic dimming, but have low response speed and poor suitability, and are difficult to popularize and apply. In summary, the existing roof sunshade cannot meet the current development requirements of the intellectualization and comfort of the automobile, and therefore, an improved roof sunshade structure for the automobile is needed to solve the above technical drawbacks. Disclosure of Invention Therefore, the invention aims to provide an automatic rolling device for an automobile roof, which is used for improving the problems that the existing rolling and unfolding mechanism for the sunshade curtain can generate clamping stagnation, abnormal sound and the like after long-term use, so that the sunshade curtain is wrinkled. In order to achieve the above purpose, the present invention provides the following technical solutions: The utility model provides an automatic coiling mechanism of car roof, sets up in the inboard skylight below of frame, including sunshade screen and the wind-up roll that is used for rolling the sunshade screen, the wind-up roll is put along the width direction of frame and is rotated and set up in the frame, the both ends of wind-up roll all are connected with the mount, each the mount all is connected with the frame surface, and the surface of each mount all is equipped with drive wind-up roll pivoted driving piece, each the equal elastic sliding connection in surface of mount has the slider along sunshade screen direction of motion, and rotates jointly between two sliders and be connected with the movable cylinder, the movable cylinder sets up in one side of keeping away from the sunshade screen and with wind-up roll parallel interval setting, and the horizontal height of movable cylinder is greater than the wind-up roll, the one end of sunshade screen width direction walk around movable cylinder surface earlier then with the fixed surface of wind-up roll, and the other end of sunshade screen width direction is equipped with the guide block, and each guide bar all is connected with the guide bar along the direction of motion of sunshade screen, each guide bar all rotates and sets up at the frame surface, and each guide bar all is equipped with the guide bar with the side of frame, and the guide bar i
