AI Technical Summary
The existing sunroof sunshades are under large width and large length spans. The curtain is too large, the driving power is high, and the noise is high. There are problems such as sagging curtains, side wear and opening and closing friction noise, which is difficult to meet the lighting of different drivers and Shading needs.
The split sunshade structure is adopted, and the intermediate guide rail is added between the traditional left and right guide rails, which is connected to the front cross beam, and the sunshade structure is divided into left and right scrolls with left and right curtain cloth to be placed. The left and right scrolls are respectively equipped on the left and middle guide rails. Between the middle guide rail and the right guide rail, the width of the single-piece pen is reduced, and the operating resistance and power demand are reduced.
The stable operation of the sunshade curtain cloth is achieved, meeting the sunshade needs of different drivers, reducing operating resistance and power needs, reducing the sagging and wear of the curtain, improving the performance and long-term safety.

Abstract
Description
Technical Field
[0001] The invention relates to skylight technology, in particular to a split sunshade curtain structure. Background Art
[0002] With the development of automobile technology, the demand for lighting, ventilation and space in the car is getting higher and higher. The existing sunroof is growing in front and back length while adapting to the width of the whole vehicle. This results in the use of sunshades with a large width and length. The curtain is heavy, the driving power is large, the operating current of the driving motor is large, the operating noise is large, and the sagging amount is increased. The side of the curtain is severely worn and the friction noise when opening and closing is large, which affects the stability and long-term use of the curtain. In addition, the sunshade opens in the front and back directions, and the width cannot meet the different lighting and shading needs of the driver and co-driver, as well as the back rows corresponding to the driver and co-driver respectively. Summary of the invention
[0003] The present invention provides a split sunshade curtain structure which has a simple structure, is conducive to the safe and stable operation of the sunshade curtain fabric, and meets different sunshade requirements in different driver and co-driver positions.
[0004] The technical solution adopted by the present invention is: a split sunshade curtain structure, including a front crossbeam and left and right guide rails, the left and right ends of the front crossbeam are respectively connected to the front ends of the left and right guide rails, and the characteristic is: it also includes a middle guide rail, the front end of the middle guide rail is connected to the middle position of the front crossbeam and is located in the middle of the left and right guide rails, and the left and right sunshade curtain inner slide grooves corresponding to the sunshade curtain outer slide grooves on the left and right guide rails are respectively arranged on both sides of the middle guide rail, and the left and right reels are respectively connected between the rear end of the middle guide rail and the rear end of the left and right guide rails, and the left and right sunshade curtain fabrics are respectively wound on the left and right reels, the outer side of the left sunshade curtain fabric is connected to the sunshade curtain outer slide groove on the left guide rail, and the inner side is connected to the left sunshade curtain inner slide groove of the middle guide rail, the outer side of the right sunshade curtain fabric is connected to the sunshade curtain outer slide groove on the right guide rail, and the inner side is connected to the right sunshade curtain inner slide groove of the middle guide rail; the lower end of the middle guide rail is correspondingly connected to the center trim panel through a buckle.
[0005] The inner holes of the reels on either side of the left and right reels are respectively plugged into the output shafts of the reducer parts of the two driving motors.
[0006] The reducer part and the motor part of the driving motor are both at the same level as the middle guide rail, and the driving motor is supported on the middle decorative plate.
[0007] Two driving motors are respectively connected to the opposite inner sides of the left and right reels.
[0008] The two driving motors are supported on the lower decorative covers of the corresponding cover-mounted reels.
[0009] The present invention adds a middle guide rail between the traditional left and right guide rails and connects it to the front crossbeam, which is beneficial to meet the demand for strengthening the overall sunroof structure when the front-to-back length of the roof sunroof is long, and divides the overall sunshade curtain structure into left and right rollers to match the left and right sunshade curtain cloths for retraction and extension. The left and right rollers are respectively assembled between the left guide rail and the middle guide rail, and the middle guide rail and the right guide rail. The left and right sunshade curtain cloths effectively divide the traditional sunshade curtain into two. The width of a single piece of sunshade curtain cloth meets the requirements of the driver and co-driver positions. The weight of a single piece is small, and the running resistance and running power are greatly reduced. On the basis of reducing the width of a single piece, the curtain cloth is effectively prevented from sagging, thereby improving the use performance and meeting the requirements of stable and long-term safe operation of the sunshade curtain cloth. The left and right rollers are respectively driven by drive motors, and the motor and reducer parts of the drive motor are at the same height, supported on the center trim panel or the decorative cover under the roller, which can reduce the height space occupied by the skylight in the vehicle and improve the driving space in the vehicle. BRIEF DESCRIPTION OF THE DRAWINGS
