Description

Technical Field

[0001] The present application relates to the technical field of automobile parts, and in particular to a front door B-corner assembly. Background Art

[0002] In automotive design, the B-pillar's joint structure and sealing performance significantly impact the safety and comfort of the vehicle. The B-pillar is a crucial component connecting the front and rear doors, and its joint design directly impacts the door's sealing, sound insulation, and aesthetics.

[0003] Currently, many vehicles rely on traditional methods for B-pillar corner installation and positioning, using visual inspection or physical contact to determine if the connection between the sealing strip and the B-pillar guide groove is flush, thereby verifying proper installation of the components at the B-pillar corner. However, this installation method relies heavily on the assembler's experience, making it difficult to establish a unified installation standard. Inexperienced assemblers can easily create gaps between the front door and the B-pillar, resulting in poor sealing performance of the sealing strip, which in turn affects interior noise control and the user experience.

[0004] Related prior arts such as the Chinese patent application "Automobile Door and Automobile", application number: CN202021059923.1; discloses that the automobile door includes a front door and a rear door, and the inner top of the rear door is provided with a rear sealing strip and a rear door corner, the rear door corner is provided at the front end of the rear sealing strip, and the rear door corner is connected to the B-pillar trim of the automobile; the inner top of the front door is provided with a support plate, a front sealing strip and a front door corner, the support plate is provided below the front sealing strip, the front door corner is provided at the rear end of the front sealing strip and will wrap the support plate, and the front door corner is used to overlap with the rear door corner when the front door is closed.

[0005] The existing B-pillar angle design fails to effectively address these issues, resulting in poor sealing performance when the door is closed. Therefore, there is an urgent need for an improved B-pillar angle design that optimizes installation, improves sealing performance, and reduces noise. Utility Model Content

[0006] The technical problem to be solved by the present application is to provide a front door B-pillar corner assembly to solve the problem of no reference for installation in the prior art, thereby improving the reliability of the installation of various components at the B-pillar corner.

[0007] The technical solution adopted in this application is: a front door B-pillar corner assembly, including a guide groove corner and a sheet metal part, the guide groove corner includes a side panel, and a back panel and a support member connected to the side panel, the support member is embedded with an insert, the insert portion protrudes from the inner wall surface of the side panel to form an installation reference surface, there is a distance between the support member and the back panel, the sheet metal part is embedded between the support member and the back panel, the sheet metal part is in contact with the inner wall surface of the back panel, and the sheet metal part includes a base plate, and the base plate is in contact with the installation reference surface.

[0008] Compared with the prior art, the advantages of the present application are that, first, the guide groove corner structure is optimized. The guide groove corner of the present application includes side panels, back panels and support members. Through the structural design of the guide groove corner, the guide groove corner includes side panels and back panels, so that the guide groove corner structure can provide multiple reference surfaces to match the installation of other components at the front door B-pillar.

In conjunction with the base plate provided on the sheet metal, the base plate is fitted with the installation reference surface, thereby achieving high-precision positioning of the sheet metal and the guide groove corner. Thirdly, there is a gap between the support member and the back panel of the present application. The sheet metal portion is partially embedded between the support member and the back panel, and the sheet metal portion is fitted with the inner wall surface of the back panel, which also plays a role in limiting the sheet metal, thereby making the installation accuracy between the sheet metal and the guide groove corner higher. In summary, the present application solves the problem of no reference for installation in the prior art, thereby improving the reliability of the installation of various components at the B-pillar corner.

[0009] In some embodiments of the present application, the present application further includes a first sealing strip, which is an elongated strip and is mounted above the support member. In the present application, the first sealing strip implements a sealing structure at the top of the front door B-pillar corner, effectively preventing the intrusion of moisture and dust.

[0010] In some embodiments of the present application, the top of the sheet metal component is bent toward the support member to form a top bar, with a gap between the top bar and the top surface of the support member. This bend in the top of the sheet metal component increases the strength of the structure. The gap between the top bar and the support member helps reduce stress concentration, improve overall stability, and minimize the risk of deformation.

The guide groove joint 1 includes a side panel 2, a back panel 3 connected to the side panel 2, and a support member 4. This allows the guide groove joint 1 structure to provide multiple reference surfaces for the installation of other components at the front door B-pillar. The support member 4 is embedded with an insert 5, which partially protrudes from the inner wall of the side panel 2 to form an installation reference surface 6. The sheet metal component 7 includes a base plate 8, which mates with the installation reference surface 6, achieving high-precision positioning of the sheet metal component 7 and the guide groove joint 1. There is a gap between the support member 4 and the back panel 3. The sheet metal component 7 is partially embedded between the support member 4 and the back panel 3, and partially mates with the inner wall of the back panel 3, which acts as a restraint on the sheet metal component 7, thereby improving the installation accuracy between the sheet metal component 7 and the guide groove joint 1.

[0032] Example 2, as Figures 2 to 3 As shown, the present application also includes a first sealing strip 9, which is a long strip structure and is installed above the support member. In the present application, the first sealing strip 9 realizes the sealing structure setting at the top of the front door B-pillar corner, effectively preventing the intrusion of moisture and dust.

[0033] The top of the sheet metal 7 is bent toward the support member 4 to form a top bar 10. A gap exists between the top bar 10 and the top surface of the support member 4. The bent top of the sheet metal 7 forms the top bar 10, increasing the strength of the structure. The gap between the top bar 10 and the support member 4 helps reduce stress concentration, enhance overall stability, and mitigate the risk of deformation.

[0034] The first sealing strip 9 is connected to the sheet metal member 7 via a top strip 10. The top strip 10 is embedded in the first sealing strip 9. The bottom of the first sealing strip 9 is in contact with the top surface of the support member 4, and the end of the first sealing strip 9 abuts the inner wall surface of the side panel 2. The connection design between the top strip 10 and the first sealing strip 9 ensures the effectiveness of the installation of the first sealing strip 9.

[0035] The rest of the content of the second embodiment is the same as that of the first embodiment.

[0036] Example 2, as Figures 1 to 5 As shown, the present application further includes a cover plate 11, which covers the front side of the support member 4. The guide groove joint 1 also includes a triangular piece 12 with a triangular sheet structure. The triangular piece 12 is located on one side of the cover plate 11 and includes two straight edges and an inwardly concave arc edge. In other words, the front side of the support member 4 constitutes the reference surface for the installation of the cover plate 11, enabling high-precision installation of the cover plate 11.

[0037] The present application further includes a second sealing strip 16 , which includes a main body 14 , a curved portion 15 and a straight portion 13 . The bottom surfaces of the straight portion 13 and the curved portion 15 are respectively connected to the top surface of the main body 14 .

[0038] The main body 14 and straight strip 13 are arranged on the inner wall of the cover plate 11. One side of the straight strip 13 is in contact with one side of the triangular member 12, and the top of the straight strip 13 is in contact with the bottom of the support member 4. The installation and position-limiting design of the second sealing strip 16 ensures its stability and reliability during use.

[0039] The curved portion 15 is arranged along the arc edge of the triangular member 12, and the triangular member 12 is located in the space enclosed by the straight portion 13, the curved portion 15, and the first sealing strip 9. At this point, the present application completes the installation and positioning of the first sealing strip 9 and the second sealing strip 16, which can effectively ensure the installation accuracy of the first sealing strip 9 and the second sealing strip 16.

[0040] The structure of one side of the sheet metal part 7 is adapted to the arc edge of the triangular part 12 , and there is a distance between the sheet metal part 7 and the triangular part 12 . The main body 14 and the curved part 15 are installed on one side of the sheet metal part 7 , and one side of the sheet metal part 7 is embedded in the main body 14 and the curved part 15 .

[0041] The insert 5 is provided with a limiting hole, which is located within the mounting reference surface 6. The inner wall surface of the side panel 2 is provided with a positioning post, which is embedded in the positioning hole. In this application, the additional positioning hole and positioning post play a role in determining the relative position of the insert 5 and the guide groove corner 1, thereby ensuring the connection accuracy between the insert 5 and the guide groove corner 1.

[0042] In this application, the guide groove corner 1 is molded using plastic injection molding due to its mounting structure and the difficulty of molding the product. Unavoidably, it will deform under excessive force. Therefore, using only the guide groove corner 1 to position and install the sheet metal component 7 is insufficient. Therefore, this application further incorporates an insert 5, which can be made of a hard material such as metal, to ensure installation accuracy throughout the entire front B-pillar corner.

[0043] The rest of the content of the third embodiment is the same as that of the first or second embodiment.
