FRONT CONNECTING ROD FOR SUNROOF LINKAGE, SUNROOF LINKAGE AND SUNROOF ASSEMBLY

Abstract

A front connecting rod for a sunroof linkage, a sunroof linkage, and a sunroof assembly. The sunroof linkage is configured to drive front glass of a sunroof assembly to slide relative to rear glass, and the front connecting rod is configured to connect a glass-supporting rod of the sunroof linkage to a front slider. The front connecting rod may have an anti-turn-over structure, configured to be matched in shape to a sealing strip disposed on a peripheral edge of the rear glass, so as to prevent the sealing strip from turning over when the sunroof linkage drives the front glass to slide. The front connecting rod for a present sunroof linkage enables a sunroof to open to the maximum extent, and during sliding will not cause the sealing strip of the rear glass to be turned over and folded.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0013] A better understanding of other features and advantages of the present invention will be gained through the preferred embodiments described in detail below in conjunction with the drawings, in which identical reference labels indicate identical or similar components.

[0014] FIG. 1 is a partial schematic drawing of a sunroof linkage in the prior art.

[0015] FIG. 2 is a partial schematic drawing of the sunroof linkage in FIG. 1 when in contact with a sealing strip of rear glass.

[0016] FIG. 3 is a partial schematic drawing of an embodiment of a sunroof linkage according to the present invention.

[0017] FIG. 4 is a partial schematic drawing of the sunroof linkage in FIG. 3 when in contact with a sealing strip of rear glass.

DETAILED DESCRIPTION

[0018] The implementation and use of embodiments are discussed in detail below. However, it should be understood that the particular embodiments discussed merely demonstratively illustrate specific ways of implementing and using the present invention, without limiting the protection scope of the present invention.

[0019] As used herein, directional expressions such as “up”, “down”, “front”, “rear”, “left” and “right” are not absolute. In the drawings, the front of a vehicle is at the left, and the rear of the vehicle is at the right. These directional expressions are appropriate when the various components are arranged as shown in the figures, but when the positions of the various components in the figures change, these directional expressions will also change accordingly. Moreover, the sliding mechanism of the linkage shown is a sliding mechanism located at the left side of the front glass; a sliding mechanism at the right side has the same operating principles, and therefore is not shown.

[0020] FIG. 3 is a partial schematic drawing of a preferred embodiment of a sunroof linkage according to the present invention; FIG. 4 is a partial schematic drawing of the sunroof linkage in FIG. 3 when in contact with a sealing strip 5 of rear glass 6. In fact, the sunroof linkage shown in FIGS. 3 and 4 is an improved solution proposed on the basis of the existing sunroof linkage shown in FIGS. 1 and 2; thus, parts which are the same in both can be understood by referring to the background art section herein, and are not described again here.

[0021] The improved feature of the present invention is that, in contrast to the front connecting rod 100 of the sunroof linkage in the prior art, the sunroof linkage according to the present invention comprises a novel front connecting rod 1 for connecting a front end of a glass-supporting rod 3 to a front slider 4; this front connecting rod 1 has an anti-turn-over structure matched in shape to the sealing strip 5. More specifically, due to this anti-turn-over structure, the sunroof linkage according to the present invention can drive front glass (not shown) to slide rearwards above the rear glass 6 until a front end of the front glass is flush with a front end of the rear glass 6 in the longitudinal direction of the vehicle (i.e. enables the sunroof to open to the maximum extent), and the sealing strip 5 of the rear glass will substantially not be pushed up by the front connecting rod 1 and thereby turned over and folded during the sliding of the linkage; thus, the sealing strip 5 will not produce abnormal noises caused by turning over and springing back, and has a longer service life. Specifically, the rear glass 6 may be securely installed at a rear part of the sunroof frame; or be configured to be inclinable relative to a motor vehicle body by a predetermined angle, i.e. can be tilted up.

[0022] Preferably, as shown in FIGS. 3 and 4, in contrast to the triangular front connecting rod 100 in the prior art, a recess 11 is formed on an edge of the front connecting rod 1 according to the present invention that faces the sealing strip 5 (i.e. an edge corresponding to the oblique edge 101 of the front connecting rod 100), to constitute the anti-turn-over structure of the front connecting rod 1. When the sunroof linkage slides to a position where the front connecting rod 100 comes into contact with a lateral front end 51 of the sealing strip 5, the presence of the recess 11 prevents significant positional interference of the front connecting rod 1 with the sealing strip 5; thus, the sealing strip 5 will substantially not be pushed up by the front connecting rod 1 and thereby turned over and folded.

[0023] More preferably, in order to obtain a better anti-turn-over effect, an included angle formed by a recessed edge of the recess 11 is less than or equal to 90°. For example, as shown in FIG. 4, the edge of the front connecting rod 1 that faces the sealing strip 5 comprises an upper edge 111 extending substantially in a vertical direction and a lower edge 112 extending substantially in a horizontal direction, so as to form the recess 11 having a substantially right-angled recessed edge. To facilitate processing, the right-angled included angle formed by the upper edge 111 and lower edge 112 is rounded to form a smooth transition. Of course, the included angle formed by the upper edge 111 and lower edge 112 may also be an acute angle, as long as strength requirements for the front connecting rod 1 and process feasibility are satisfied. According to another implementation variant, the included angle formed by the upper edge 111 and lower edge 112 may also be an obtuse angle slightly larger than a right angle, on condition that the recess 11 is able to achieve the anti-turn-over effect.

[0024] The technical content and technical characteristics of the present invention have been disclosed above. However, it will be understood that within the creative thinking of the present invention, those skilled in the art could make various changes and improvements to the concept disclosed above, but all such changes and improvements would fall within the protection scope of the present invention.

[0025] The description of the embodiments above is exemplary and non-limiting; the protection scope of the present invention is determined by the claims.
