C-column sealing structure of automobile rear door and window frame
Technical Field
The invention relates to the technical field of automobiles, in particular to a C-column sealing structure of an automobile rear door and window frame.
Background
With the rapid development of the automobile industry, the NVH performance of automobiles is more and more concerned by consumers; the problem of wind noise is the most common when the automobile runs at high speed, at present, two seals are gradually eliminated, and two semi-seals are normalized; the attention of consumers to the main driving wind noise only rises from the past to the attention of the whole vehicle, so the comfort of the rear-row passengers is improved to be a necessary trend.
The section of the existing product mostly adopts a buckle clamping form, the buckle is fixed in an intermittent way, and the NVH performance is poor; if current product adopts the joint structure, all uses U type draw-in groove structure basically in the design, what the material chooseed for use is closely knit glue adds steel skeleton texture, and not only with high costs, appearance quality is poor moreover, and the surface has the steel band spareribs trace.
Disclosure of Invention
The invention aims to provide a C-pillar sealing structure of an automobile rear door and window frame, wherein a C-pillar sealing strip is fixed on a C-pillar decorative cover plate through an integrally extruded clamping structure, the whole C-pillar sealing strip and the cover plate are of equal sections from top to bottom, the sealing performance is enhanced, the assembling process is more convenient, and the whole C-pillar sealing strip is in lap joint sealing with a side wall corner window assembly by virtue of a sealing mantle, so that the effects of retaining water and ash are achieved, the NVH performance and the appearance quality are improved, and the problems in the background art are solved.
In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a door and window frame C post seal structure behind car, includes C post trim cover board, C post sealing strip, side wall angle window assembly and back door panel beating assembly, C post trim cover board is installed on back door panel beating assembly, C post sealing strip joint is on C post trim cover board, C post sealing strip includes the barred body, fixture block, supplementary fixed block, sealed mantle and outward appearance mantle, the draw-in groove has been seted up on the C post trim cover board, the fixture block joint is in the draw-in groove, supplementary fixed block joint is on C post trim cover board, overlap joint on one side of sealed mantle is on side wall angle window assembly, outward appearance mantle one side overlap joint is on back door panel beating assembly.
Preferably, the clamping groove is a wedge-shaped groove.
Preferably, an elastic rubber pad is glued to the position, close to the auxiliary fixing block, of the C-column decorative cover plate.
Preferably, the strip body, the fixture block, the auxiliary fixing block, the sealing mantle and the appearance mantle are integrally formed on the strip body.
Preferably, the strip body is provided with a glue stopping line.
Preferably, the sealing mantle surface is provided with a velvet layer.
Compared with the prior art, the invention has the beneficial effects that:
the C post sealing strip is fixed on C post decorative cover board through integrative joint structure of extruding, and whole C post sealing strip is the uniform cross section with apron from the top down, has strengthened sealing performance, and it is more convenient also to make the assembling process simultaneously, and whole C post sealing strip relies on sealed cloak and side wall corner window assembly overlap joint sealed to play the effect of manger plate, fender ash, promoted NVH performance and appearance quality simultaneously.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: a C-pillar sealing structure of an automobile rear door and window frame comprises a C-pillar decorative cover plate 1, a C-pillar sealing strip 2, a side wall corner window assembly 3 and a rear door metal plate assembly 4, wherein the C-pillar decorative cover plate 1 is installed on the rear door metal plate assembly 4, and the C-pillar sealing strip 2 is clamped on the C-pillar decorative cover plate 1;
the C column sealing strip 2 comprises a strip body 5, a fixture block 6, an auxiliary fixing block 7, a sealing cloak 8 and an appearance cloak 9, the C column sealing strip 2 is integrally formed by adopting a dense glue, the strip body 5, the fixture block 6, the auxiliary fixing block 7, the sealing cloak 8 and the appearance cloak 9 are integrally formed on the strip body 5, a velvet layer 13 is arranged on the surface of the sealing cloak 8, a clamping groove 10 is formed in the C column decorative cover plate 1, the fixture block 6 is clamped in the clamping groove 10, the clamping groove 10 is a wedge-shaped groove, the fixture block 6 is convenient to embed, the auxiliary fixing block 7 is clamped in the C column decorative cover plate 1, an elastic rubber pad 11 is spliced at a position, close to the auxiliary fixing block 7, on the C column decorative cover plate 1, the connection tightness is enhanced, one side of the sealing cloak 8 is lapped on the side wall corner window assembly 3, a glue stopping line 12 is arranged on the strip body 5.
The structure principle is as follows: the C-pillar sealing strip 2 is assembled on the door C-pillar decorative cover plate 1 through a self clamping block 6, the C-pillar decorative cover plate 1 adopts a wedge-shaped groove, the embedding of the clamping block 6 is facilitated, the C-pillar decorative cover plate 1 is assembled on the rear door metal plate assembly 4, and when the rear door is in a closed state, the sealing cloak 8 is lapped and sealed with the side wall corner window assembly, so that wind, water, ash and the like can be prevented from being poured into the vehicle; c post sealing strip 2 is fixed on C post decorative cover board 1 through the joint structure that an organic whole was extruded, and C post sealing strip 2 is equal cross-section from the top down with C post decorative cover board 1, has strengthened sealing performance, also makes the assembling process more convenient simultaneously.
