Detailed Description

The making and using of the embodiments are discussed in detail below. It should be understood, however, that the specific embodiments discussed are merely illustrative of specific ways to make and use the application and do not limit the scope of the application. The structural position of the various components as described, such as the directions of up, down, top, bottom, etc., is not absolute, but rather relative. When the individual components are arranged as shown in the figures, these directional expressions are appropriate, but when the position of the individual components in the figures changes, these directional expressions also change accordingly.

Herein, "front", "rear", "upper", "lower" are defined in terms of the actual direction of the vehicle, wherein "front", "rear" are relative to the direction of travel of the vehicle.

For the male curtain rolling mechanism with the edge strips arranged on the edges of the curtain cloth, when the curtain cloth is in the rolling position, the edge strips are also rolled on the scroll component. The edging strip is adapted to guide the cord fabric on the rail as the cord fabric moves from the rolled position to the unrolled position or vice versa, while the reel assembly provides a reel force or a tensile force of the rolling to avoid cord fabric jumping and to prevent wrinkling. It has been appreciated that in the extended position, due to the distance between the rail and the roller assembly of the roller shade mechanism, a portion of the edging in this area is not supported by the rail, which causes the edging to have a tendency to be stretched and deformed by the roller force exerted on this portion of the edging. When the edging is made of materials such as thermoplastic vulcanized rubber (TPV), the edging in the area can generate deformation and arch defects through the test of endurance test, and if the top space of the area is insufficient in the vehicle body environment, the edging can scratch the vehicle body sheet metal to generate abnormal noise when the curtain cloth runs. This problem of deformation is more serious especially in high temperature environments (e.g., temperatures of 50 ℃ or higher in the interior of a vehicle in summer).

According to the concept of the application, the roller shade mechanism comprises a rolling device and a curtain cloth which is rolled on the rolling device and can move between an unfolding position and a rolling position, wherein the rolling device comprises a scroll component for winding the curtain cloth. The edge of the curtain cloth is provided with a side strip which is suitable for guiding the curtain cloth to move, wherein in the unfolding position, the side strip is not wound on the scroll component.

It will be appreciated that the absence of the edging being wound onto the reel assembly means that the edging does not completely cover the edges of the curtain but at least ensures the guiding action of the edging on the curtain within the rail. In this way, this application is through shortening strake length, sets up strake length to be not rolled up on the spool subassembly in the expansion position of curtain cloth, and spool force can not directly be exerted on the strake, has avoided the strake to be by the risk of tensile deformation. It will be appreciated that the deployed position of the curtain is generally closer to the front of the body and the stowed position is closer to the rear of the body, although the reverse arrangement is not precluded.

Fig. 3 and 4 illustrate a roller shade mechanism according to one embodiment of the present application, with the understanding that the hembar of the shade edge is symmetrically disposed with respect to the longitudinal central axis of the roller shade mechanism and the construction and functional principles are identical. In the illustrated embodiment, the reel assembly 210 of the winding device 200 provides a winding reel force to the shade 300, the hembar 400 extends along the edge of the shade 300, and the hembar 400 forms a distance D with the reel assembly 210 when the end of the shade in the direction of the shade winding is in the unwind position. The roller shade mechanism also includes a rail 11 along which the hembar 400 is adapted to guide movement of the shade 300, such as pulling the shade out of the roller assembly, by a drive assembly along the rail 11. Advantageously, the distance D is determined by the distance L between the reel assembly 210 and the guide rail. In other words, the distance D can be adjusted with respect to the distance L depending on different needs.

In some embodiments, as shown in connection with fig. 5 and 6, the distance D may be greater than or equal to the distance L between the spool assembly 210 and the rail 11 such that the edge strip 400 is fully supported by the rail 11 and does not extend beyond the rail 11. In this way, the hems within the rail 11 still act as guides for the curtain but are not substantially subject to tension from the reel assembly or can be deformed and corrected by the rail, and in this distance between the reel assembly 210 and the rail 11 there is no tension due to friction, so that the extent of deformation elongation or arching of the hems is significantly reduced.

In some embodiments, the distance D may also be slightly less than the distance L, i.e., the ends of the strakes slightly extend beyond the rails. As the interval between the edge strips and the scroll component is still kept and most of the edge strips are supported in the guide rail, the deformation degree of the edge strips can be reduced in the running process of the curtain cloth.

Alternatively, the hems are attached to the edges of the curtain by stitching, adhesive, heat pressing or welding. For the curtain cloth of the mesh fabric (single-layer fabric) or the multi-layer composite curtain cloth, the strake extending along the edge of the curtain cloth can avoid the problem of strake deformation under the premise of ensuring good guiding effect.

It is understood that plastic material's strake easily takes place to warp under high temperature environment, but the scheme of this application is applicable to metal material's strake equally, and even metal strake's deformation trend is less, outside shorter strake of guide rail or the outside no strake of guide rail have all effectively avoided the noise that strip and automobile body panel beating striking or friction produced in the curtain cloth operation in-process when the expansion position. In addition, shortened strakes also mean a more economical cost.

The male curtain rolling mechanism can effectively avoid deformation trend of the edge strip by setting the edge strip at the unfolding position of the curtain cloth to be not wound on the reel assembly, so that smoothness or damage resistance of the curtain cloth in the moving process between the unfolding position and the winding position is ensured, and passengers can obtain more satisfied use comfort.

It should be understood herein that the embodiments shown in the figures illustrate only alternative shapes, sizes and arrangements of roller shade mechanisms according to the present application, which are illustrative only and not limiting, as other shapes, sizes and arrangements may be employed without departing from the spirit and scope of the present application.

While the technical content and features of the present application have been disclosed above, it will be understood that those skilled in the art, under the teaching of the present application, may make various changes and modifications to the above disclosed concepts, which are within the scope of protection of the present application. The above description of embodiments is illustrative and not restrictive, and the scope of the application is defined by the claims.
