[0042] Combine Figure 1-Figure 2 The door B-pillar cover positioning structure in this application is mainly used for the rapid positioning and installation of the B-pillar cover 2 on the door inner panel 1. Specifically, necessary structures are set on the B-pillar cover 2 and the door inner panel 1 respectively to ensure the quick installation and assembly of the B-pillar cover 2 and the reliability of the connection.

[0043] In addition, by providing other auxiliary structures, the matching stability and flatness of the B-pillar cover 2 and the decorative bright strips 12 and other surrounding parts on the door inner panel 1 are ensured, thereby improving the appearance texture.

[0044] See also Figure 3-Figure 5 The door B-pillar mainly includes a door inner panel 1 and a B-pillar cover 2 , and the door B-pillar cover positioning structure is specifically arranged between the door inner panel 1 and the B-pillar cover 2 .

[0045] Positioning and connection installation can be achieved by providing a mounting portion 21 and a positioning portion 22 on the B-pillar cover 2 and providing a mounting hole 31 and a positioning hole 32 on the door window frame reinforcement plate 3 connected to the door inner panel 1.

[0046] The B-pillar cover 2 is positioned and mounted by the corresponding cooperation between the positioning portion 22 and the positioning hole 32, and the B-pillar cover 2 is connected and mounted on the door inner panel 1 by the corresponding cooperation between the mounting portion 21 and the mounting hole 31. Specifically, the B-pillar cover 2 is connected and mounted on the door window frame reinforcement plate 3 of the door inner panel 1 by fastening screws, thereby maximizing the speed, reliability and stability of the alignment assembly.

[0047] In one specific embodiment, the mounting hole 31 comprises a sheet metal square hole provided on the vehicle door window frame reinforcement plate 3 , and the positioning hole 32 comprises an L-shaped clamping hole provided on the vehicle door window frame reinforcement plate 3 .

[0048] The sheet metal square hole provides a structural basis for the connection and installation of the B-pillar cover 2. A plastic nut seat of corresponding size is installed in the sheet metal square hole, which can be used for fastening screws to pass through and fix (the plastic nut seat and fastening screws are not shown in the figure).

[0049] The L-shaped mounting hole is specifically a special-shaped mounting hole provided on the door window frame reinforcement plate 3 , which can facilitate the insertion of the positioning portion 22 on the B-pillar cover plate 2 and can be assembled after insertion to achieve positioning mounting before connection and fixation.

[0050] The B-pillar cover plate 2 includes a cover plate outer plate 2 a and a cover plate inner plate 2 b . The cover plate outer plate 2 a and the cover plate inner plate 2 b are bonded together by strong glue 6 to form the main structure of the B-pillar cover plate 2 .

[0051] The mounting portion 21 and the positioning portion 22 are provided on the cover inner panel 2 b . Furthermore, in order to enable snap-fit ​​assembly after the positioning portion 22 extends into the positioning hole 32 , the positioning portion 22 includes a positioning hook 23 protruding toward the door inner panel 1 .

[0052] Preferably, the positioning hook 23 is connected to the side wall of the cover inner plate 2b, which can reduce the gap between the cover inner plate 2b and the door window frame reinforcement plate 3 during the relative buckle connection and better fit them.

[0053] A downward-bent extension plate 25 is connected to the side wall of the inner plate 2b of the cover plate, and the extension plate 25 is connected to the bottom of the positioning hook 23. The width of the positioning hook 23 protruding from the side wall of the inner plate 2b of the cover plate is greater than the width of the extension plate 25 protruding from the side wall of the inner plate 2b of the cover plate, so that the edge of the part where the positioning hook 23 protrudes from the extension plate 25 constitutes the first direction limiting surface A of the positioning hook 23 when it is positioned and clamped.

[0054] In order to achieve effective clamping, the positioning hook 23 includes a positioning groove 24 with an upward opening. The lateral groove wall of the positioning groove 24 close to the vehicle door window frame reinforcement plate 3 constitutes the second direction limiting surface B of the positioning hook 23, and the groove bottom of the positioning groove 24 constitutes the third direction limiting surface C of the positioning hook 23.

[0055] From the perspective of facilitating understanding, after the positioning hook 23 in this embodiment is extended into the positioning hole 32, it is adjusted and pushed in three different dimensions. While achieving positioning, the mounting portion 21 on the B-pillar cover 2 is positioned opposite to the mounting hole 31 on the door window frame reinforcement plate 3.

[0056] Specifically, the first direction, the second direction, and the third direction represent a direction along the front of the vehicle, a direction along the inside of the vehicle, and a vertical direction, respectively.

[0057] During the assembly process, first extend the positioning hook 23 of the B-pillar cover 2 into the corresponding positioning hole 32 along the second direction, that is, toward the interior of the vehicle, and then push it in the first direction, that is, toward the front of the vehicle, and then push it vertically upward along the third direction to complete the rapid positioning of the B-pillar cover 2, and then use the fastening screws in sequence to align with the through holes 21b of the installation part of the B-pillar cover 2 for vertical fixing and locking.

[0058] Through the above assembly process, the quickness of installation can be improved to the greatest extent, and the connection can be stable and reliable.

[0059] To enhance the structural strength of the positioning hook 23, a reinforcing rib 26 is provided at the bottom of the positioning hook 23, which connects to the sidewall of the cover inner panel 2b. Specifically, the reinforcing rib 26 extends from the positioning hook 23 toward the bottom of the sidewall inside the vehicle door, extending along the outer contour of the positioning hook 23 to the sidewall of the cover inner panel 2b, effectively reinforcing the positioning hook 23.

[0060] From the installation perspective, the mounting portion 21 in this embodiment is connected to the downwardly bent portion of the extension plate 25, and includes a bent plate 21a connected to the edge of the extension plate 25, and a through hole 21b is provided on the bent plate 21a, which is conducive to fixed connection after positioning is completed.

[0061] Combine Figure 6-Figure 7 In another specific embodiment, in order to enable the B-pillar cover 2 to be installed more accurately, the matching stability and matching flatness between the B-pillar cover 2 and surrounding parts are improved.

[0062] A support plate 27 is provided on top of the cover inner panel 2b, extending obliquely upward toward the door and window frame reinforcement plate 3. The support plate 27 allows its edge to abut against the door and window frame reinforcement plate 3, preventing the cover inner panel 2b from collapsing toward the door during assembly and ensuring stable fitting.

[0063] In order to further ensure the installation stability, sponge strips 4 and boss ribs 5 are provided on the inner side wall of the door window frame reinforcement plate 3, which can play a role of flexible extrusion and tight fitting, enhance the flexible buffering effect, and ensure stable and reliable installation performance from another angle.

[0064] A decorative bright strip 12 serving as an auxiliary decorative component is provided on the top of the door window frame reinforcement plate 3, and a limiting matching strip 28 is provided on the cover outer panel 2a. The limiting matching strip 28 includes a bending structure located at the top of the cover outer panel 2a, and the limiting matching strip 28 is provided on the upper part of the support plate 27. During the assembly process, the decorative bright strip 12 can overlap and cooperate with the limiting matching strip 28. Specifically, the bottom edge of the decorative bright strip 12 is clamped in the bending part of the limiting matching strip 28, which effectively ensures the matching flatness of the B-pillar cover 2 and the decorative bright strip 12.

[0065] Furthermore, the side of the cover inner panel 2b is provided with a folded edge 29. The door inner panel 1 includes a sheet metal trim 11 on the side. The folded edge 29 is installed around the outside of the sheet metal trim 11. The provision of the folded edge 29 can effectively shield the sheet metal trim 11 from leakage, enhancing the refined appearance.
