Description

Technical Field

[0001] This utility model belongs to the field of automotive door technology, specifically relating to a structure and installation components for an external aluminum trim panel on the BC pillar of a car door. Background Technology

[0002] The BC pillar cover is a type of "functional exterior decorative cover," hereinafter referred to as the BC pillar cover. The BC pillar cover provides structural support for the glass guide system. These BC pillar covers provide an integral holding method for the glass guide channel (GRC) and provide sufficient extension below the door waistline to maintain the glass's fit / stability at the bottom stop of the full glass section. Due to the lack of weld lines on the door sheet metal above the BC and C pillar waistlines, all FUG door structures require covers with guide rails. Of course, the cover can also serve a purely decorative purpose, utilizing other guide rails to achieve the glass lifting function. As a decorative part, it serves to decorate the exposed door sheet metal and provides different decorative styles through the selection of different materials, gloss, and colors on the exterior surface.

[0003] Currently, the automotive industry commonly uses aluminum or exposed black resin for exterior door trim panels. This contrasts with the body color and creates a visually appealing effect, adding depth and sophistication to the overall vehicle design. However, with the development of the automotive industry, meeting users' individual needs, lightweighting requirements, and the desire for a refined vehicle aesthetic has become increasingly urgent. While aluminum-clad trim panels are being used more extensively, limitations imposed by conventional door structures—such as small openings between the door glass and the outer door panel—lead to difficulties in installation. Furthermore, the shaping of the door frame and inner door panel restricts the freedom of choosing installation points, thus hindering installation and functionality.

[0004] There are two main methods for manufacturing aluminum-clad BC pillar covers: Method one involves directly extruding the BC pillar cover body and glass guide rail together, with subsequent shaping using CNC machining and stamping processes. This method requires precise cross-section of the mud channel, and the forming depth at the installation point is significantly limited by the cross-section and shape. It also demands precise installation techniques and door-connection methods, resulting in longer installation times and reduced production efficiency. Method two involves directly rolling the BC pillar cover body and glass guide rail together, with subsequent shaping using CNC machining and stamping processes. This method shares similar drawbacks with Method one: it requires precise cross-section of the mud channel, and the forming depth at the installation point is significantly limited by the cross-section and shape. It also demands precise installation techniques and door-connection methods, resulting in longer installation times and reduced production efficiency. Furthermore, the surface gloss is limited by the material itself. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a structure and installation components for the external aluminum trim panel of the BC pillar of a car door, which solves the problem that the existing aluminum exterior cover of the car door can not only meet the function of glass lifting, but also meet the installation method and appearance requirements of the aluminum cover. At the same time, it solves the limitation of conventional car door structure, and can freely arrange the installation method and arrangement according to the needs of the car door to meet the on-site assembly requirements.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an aluminum trim panel structure and installation assembly for the exterior of the BC pillar of a car door, used to cooperate with the lifting and lowering of the glass, including a cover plate body and a bracket body. The cover plate body has an integrally formed upper half of a lifting guide rail, and the bracket body has an integrally formed lower half of a lifting guide rail. After the cover plate body and the bracket body are assembled, the upper half of the lifting guide rail and the lower half of the lifting guide rail form a complete guide rail structure and realize the function of the glass lifting and lowering guide rail.

[0007] In the aforementioned structure and installation assembly for an external aluminum trim panel on the BC pillar of a car door, the cover plate body is integrally formed by aluminum extrusion, and T-shaped or L-shaped ribs are provided on the extruded cross-section.

[0008] In the aforementioned structure and installation assembly for the external aluminum trim panel of the BC pillar of a car door, a notch is formed on the inner side of the rib.

[0009] In the aforementioned structure and installation assembly of an external aluminum trim panel for a car door BC pillar, the bracket body is injection molded or insert injection molded. The bracket body has hook protrusions that connect with the ribs and notches of the cover plate body. After the bracket body and the cover plate body are assembled and installed, the hook protrusions of the bracket body will combine with the notches on the cover plate body to form an inverted structure.

[0010] In the aforementioned structure and installation assembly for the exterior aluminum trim panel of the BC pillar of a car door, double-sided tape, glue, or stainless steel press-fit brackets are provided at the mating point between the bracket body and the cover plate body, excluding the inverted structure.

[0011] In the aforementioned structure and installation assembly for the external aluminum trim panel of the BC pillar of a car door, the lower part of the bracket body is provided with sheet metal, the bracket body has a locking hole, and a locking screw is provided on the locking hole. The locking screw passes through the locking hole and locks the bracket body onto the sheet metal.

[0012] In the aforementioned structure and installation assembly for the external aluminum trim panel of the BC pillar of a car door, a bent portion is formed on the left side of the bracket body, and the bent portion is matched and installed at the left flip position of the bracket body.

[0013] In the aforementioned structure and installation assembly for the external aluminum trim panel of the BC pillar of a car door, a guide rail sealing strip is installed at the guide rail formed by the upper half and the lower half of the lifting guide rail, and glass is installed inside the guide rail sealing strip. The bracket body has an anti-detachment protrusion to prevent the guide rail sealing strip from falling off.

[0014] In the aforementioned structure and installation assembly for the external aluminum trim panel of the BC pillar of a car door, foam is provided between the sheet metal and the bracket body.

[0015] Compared with existing technologies, the advantages of this utility model are that it can satisfy both the function of glass lifting and the installation method and appearance requirements of the cover plate body. Since the bracket body is injection molded, the number or position of installation points can be arranged arbitrarily according to the stability of the product, and the clearance space can be freely adjusted according to the customer's vehicle installation method. It will not be limited by the forming depth of the installation points due to the sheet metal forming properties of the hand parts or the elongation rate of the metal material in the original solution. The installation method can also be set according to the needs of the site, such as screwing, nuts, self-tapping screws, etc., breaking the traditional customer door line first assembling the buckle and then screwing, reducing the customer's material management cost and installation labor cost. Moreover, the molding of the injection molded parts has a large degree of freedom, reducing the requirements for the assembly performance of the mud channel and the cross-sectional anti-detachment size. The strength of the guide rail can be enhanced according to the requirements, and the overall size is more stable than the original solution. The subsequent adaptation cost to the actual vehicle is low, reducing rework costs. Attached Figure Description
