rear door c-pillar system

Abstract

The invention discloses a rear door C-pillar system, which comprises a car door inner sheet metal, a car door outer sheet metal, an inner cover, an outer cover and a lower guide rail. The lower guide rail is installed between the car door inner sheet metal and the car door outer sheet metal. The cover plate and the inner cover plate are respectively located above the door outer sheet metal and the door inner sheet metal, and also include the C-pillar door frame assembly, which includes the C-pillar door frame, triangular sheet metal and upper guide rail connected as a whole, The triangular sheet metal includes rear side, front side and lower side. The rear side is connected to the C-pillar door frame, and the front side is connected to the upper rail; the inner cover is connected to the inner side of the C-pillar door frame assembly, and the outer cover is connected to the On the outer side of the C-pillar door frame assembly, the upper guide rail is connected with the lower guide rail. The C-pillar door frame assembly of the present invention is used as the installation base of the inner cover plate and the outer cover plate, which is easy to assemble and reduces the cost; and the triangular sheet metal separates the inner side and the outer side of the door, which has better sealing performance and reduces the generation of wind noise .

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a rear door C-pillar system. Background technique [0002] An existing back door C-pillar system has the following disadvantages: [0003] 1) It is difficult to realize the shape PQ: there is a 3-5mm surface difference between the outer cover of the C-pillar of the rear door, the door frame, and the side corner window, and it is impossible to achieve zero surface difference; [0004] 2) Difficult operation: After glazing is assembled, there is insufficient assembly space for the guide channel rubber strip and the cover plate assembly, repeated twisting, the rubber strip is prone to creases, and the appearance is poor; [0005] 3) Complex structure and high cost: [0006] ①The triangular cover plate assembly is composed of inner cover plate, outer cover plate, guide rail and bolts, etc., with many components, many processes and high cost; [0007] ②The triangular cover plat...

AI Technical Summary

Problems solved by technology

[0003] 1) It is difficult to realize the shape PQ: there is a 3-5mm surface difference between the outer cover of the C-pillar of the rear door, the door frame, and the side corner window, and it is impossible to achieve zero surface difference;

[0004] 2) Difficult operation: After glazing is assembled, there is insufficient assembly space for the guide channel rubber strip and the cover plate assembly, repeated twisting, the rubber strip is prone to creases, and the appearance is poor;

[0005] 3) Complex structure and high cost:

[0006] ①The triangular cover plate assembly is composed of inner cover plate, outer cover plate, guide rail and bolts, etc., with many components, many processes and high cost;

[0007] ②The triangular cover plate assembly runs through the inner and outer sides of the door, which is prone to problems such as wind noise and watertightness

[0009] 1) High cost: In order to achieve zero surface difference of the C-pillar, the door frame is welded with triangular sheet metal parts, and the high-gloss cover plate adopts two-color injection molding or painting process to achieve the strength requirement;

[0010] 2) Weak rigidity: The C-pillar structure is mainly realized through the assembly of individual parts, with many fits and weak rigidity

[0011] 3) Homework is difficult:

[0012] ①The glass must be passed from the inner side of the door to the outer side of the door through the door frame, and the assembly is completed through multiple rotating movements. The rhythm is slow and it is easy to bump into the glass;

[0013] ②The cover plate and the guide groove are installed in combination, and the appearance gap and other cooperation are difficult to guarantee
