Problems solved by technology

As a result, when the edge strip is interference-fitted with the body sheet metal, the lip edge of the edge strip will be depressed at the groove covering the outer surface of the body sheet metal, causing the lip edge to appear wavy, which will not only affect the appearance , and when the wave edge is serious, it will also cause problems such as water accumulation and dust accumulation, and the maintenance cost will be relatively high

Embodiment 1

[0080] see figure 1 , showing a partial structural schematic diagram of the glass edging assembly 2 assembled on the vehicle body 1 in the first embodiment of the present invention.

[0081] like figure 1 As shown, in the first embodiment, the front triangular window of the vehicle body 1 is installed with a front triangular window glass assembly (ie, the glass edging assembly 2). The part of the vehicle body 1 close to the front triangular window is composed of a first body sheet metal 11 and a second body sheet metal 12 spliced ​​together, and the first body sheet metal 11 and the second body sheet metal 12 are formed between the first body sheet metal 11 and the second body sheet metal 12 There are groove-like abrupt structures 13 with a width of 2.5 mm. The glass edging assembly 2 includes a glass plate 21 and a edging strip 22 arranged on the edge of the glass plate 21 . The edging strip 22 is used to seal the gap between the vehicle body 1 and the glass plate 21 . Ass...

Embodiment 2

[0088] see Figure 5 and Image 6 , Figure 5 A partial structural schematic diagram of the glass edging assembly 2 assembled on the vehicle body 1 in the second embodiment of the present invention is shown, Image 6 show Figure 5 Partial cross-sectional view of the glass edging assembly and body assembly shown.

[0089] like Figure 5 and Image 6 As shown, the difference from the first embodiment is that: in the second embodiment, the glass edging assembly 2 is the rear windshield glass assembly of the vehicle, and the edging strip 22 adopts an extrusion process The base body 223 of the edge wrapping strip 22 is bonded to the inner surface of the glass plate 21 through glue, and the part of the glass plate 21 facing the vehicle body 1 is glued and fixed by the sealing glue strip 3 .

[0090] In addition, the difference from the first embodiment is that in the second embodiment, the amount of interference between the lip 221 and the vehicle body 1 is a 2 , the fitting ...

Abstract

The invention provides an edging strip, a glass edging assembly and a vehicle. The edging strip is used for sealing between the assembled first exterior trim piece and the second exterior trim piece, the outer surface of the first exterior trim piece has a sudden change structure, and the sudden change structure includes at least one groove and / or at least one hollow groove, The abrupt structure adjoins the edge of the second exterior trim piece; the edging strip includes an elastic lip provided on the edge of the second exterior trim piece, and the lip is used to cover a portion of the abrupt structure that is recessed in the opposite direction relative to the abrupt structure to form a compensation structure , the compensation structure protrudes outward in a natural state. When the first exterior trim piece and the second exterior trim piece are assembled, the lip is elastically deformed and tightly fitted to the portion of the outer surface of the first exterior trim piece adjacent to the edge of the second exterior trim piece, and the lip is provided with a compensation structure The deformation of the part of the lip is smaller than that of other parts of the lip, and gradually decreases from the edge to the middle along the extending direction of the lip, so that the overall outer surface of the lip is flush, thereby avoiding the problem of wavy edges.

Description

technical field [0001] The present invention relates to the technical field of hemming, in particular to an anti-wavy hemming strip, a glass hemming assembly including the hemming strip, and a vehicle including the glass hemming assembly. Background technique [0002] At present, edge wrapping strips with sealing function are usually set between the body sheet metal and the window glass. Due to the tightness requirements, the edge wrap needs to be overfit with the body sheet metal, and the same interference design should be done on the same side to ensure the appearance consistency. [0003] With the development of automobile manufacturing technology, the design of body sheet metal is more and more diverse. For example, the body sheet metal of some vehicles is punched to form a long and narrow sink; for another example, the body sheet metal at the front triangle or rear triangle of some vehicles is assembled by splicing two pieces of sheet metal to form a splicing gap. The...
