Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to an A-pillar sheet metal structure, an A-pillar, and an automobile. Background Technology

[0002] The A-pillar guard plate, located on both sides of the windshield and inside the body panel, is an interior trim component of a car. MPV models typically feature a split-leg, "V"-shaped structure for the A-pillar guard plate. During installation, the lower ends of the two legs are first fixed to the dashboard, and the upper end is rotated towards the body panel for secure fastening. Unlike A-pillar guard plates in ordinary vehicles, the split-leg structure and its installation method inevitably lead to interference with the body panel's edge at the triangular window area. For example, the flange of the A-pillar guard plate can be easily cut by the edge during movement. Several methods exist to address this interference, such as increasing the gap between the A-pillar guard plate and the body panel edge, but this sacrifices visibility. Another method is to use a modular assembly approach, where the A-pillar guard plate is divided into parts and assembled separately, but this affects the overall aesthetics. Summary of the Invention

[0003] The main objective of this invention is to propose an A-pillar sheet metal structure, an A-pillar, and a car, which aims to guide the A-pillar guard plate to solve the interference problem during A-pillar guard plate assembly.

[0004] To achieve the above objectives, the present invention proposes an A-pillar sheet metal structure, comprising:

[0005] The main beam of column A extends vertically; and,

[0006] A support beam extends vertically, and its upper end is connected to the lower end of the main beam of column A, so as to divide the main beam of column A into a first segment and a second segment. The support beam and the second segment are sandwiched to form a triangular area.

[0007] The first side is located on the second section of the main beam of column A, near the supporting beam, and a guide protrusion is provided on the second section of the main beam of column A near the first side.

[0008] Optionally, the width of the guide protrusion is gradually increased in the direction closer to the first side.

[0009] Optionally, the guide protrusion is an arc-shaped protrusion.

[0010] Optionally, the thickness of the guide protrusion gradually decreases in the direction closer to the first side, or the thickness of the guide protrusion first increases and then decreases.

[0011] Optionally, the guide protrusion is disposed within a set area, which is the area on the second segment 5-7 cm away from its first side edge.

[0012] Optionally, the guide protrusion is made of silicone or metal.

[0013] Optionally, the guide protrusion and the A-column main beam are an integral structure.

[0014] Optionally, the guide protrusion and the A-column main beam are detachable structures, and the two are connected by a connector.

[0015] The present invention also proposes an A-pillar, including the A-pillar sheet metal structure and A-pillar guard plate as described above.

[0016] The present invention also proposes an automobile including the A-pillar as described above.

[0017] In the technical solution provided by this invention, a guide protrusion is provided on the second section of the A-pillar main beam near the first side, where the first side is the side of the second section of the A-pillar main beam near the supporting beam. Therefore, during the assembly of the A-pillar guard plate, the flange of the A-pillar guard plate will first contact the guide protrusion on the A-pillar sheet metal structure. The guide protrusion can prevent interference between the flange and the first side of the A-pillar sheet metal structure, greatly reducing the difficulty of assembling the A-pillar guard plate, without sacrificing the A-pillar's field of vision or affecting the overall aesthetics.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0030] The A-pillar guard plate of MPV models has a "V"-shaped split-leg structure, which is different from the A-pillar guard plate of ordinary models. The split-leg structure of the A-pillar guard plate and its installation method are prone to interference with the body sheet metal stop at the triangular window position during the installation process.

[0031] In view of this, the present invention provides an A-pillar sheet metal structure, see below. Figure 1-3 It includes: an A-pillar main beam 1 and a support beam 2. The A-pillar main beam 1 extends vertically; the support beam 2 extends vertically, with its upper end connected to the lower end of the A-pillar main beam 1, dividing the A-pillar main beam into a first segment 11 and a second segment 12. The support beam 2 and the second segment 12 form a triangular region. The side of the second segment 12 of the A-pillar main beam closest to the support beam 2 is designated as a first side 13, and a guide protrusion 3 is provided on the second segment of the A-pillar main beam near the first side 13.

[0032] By setting a guide protrusion 3 on the second section of the A-pillar main beam near the first side 13, where the first side 13 is the side of the second section of the A-pillar main beam near the support beam 2, the A-pillar guard plate flange 300 will first contact the guide protrusion 3 on the A-pillar sheet metal structure during assembly. The guide protrusion 3 can avoid interference between the flange 300 and the first side of the A-pillar sheet metal structure (normally, a sheet metal stop is set at the first side position), greatly reducing the difficulty of A-pillar guard plate assembly, without sacrificing the A-pillar visibility, and without affecting the overall aesthetics.

[0033] See Figure 3 and Figure 4 When installing the A-pillar guard plate, firstly, the lower ends 100 of the two A-pillar guard plate legs need to be fixed to the dashboard. Then, the top 200 of the A-pillar guard plate is rotated towards the A-pillar sheet metal structure. Next, the top 200 of the A-pillar guard plate is engaged with the connecting structure (e.g., a snap-fit ​​structure) on the A-pillar sheet metal structure to complete the installation. However, during the rotation of the top 200 of the A-pillar guard plate, the first side 13 of the A-pillar sheet metal structure, i.e., the sheet metal stop, is relatively thin. If there is no guide protrusion 3 on the A-pillar sheet metal structure, problems such as the A-pillar guard plate flange 300 being cut by the sheet metal stop during movement may occur, or the A-pillar guard plate may interfere strongly with the sheet metal stop, making installation impossible.

[0034] In one feasible embodiment of the present invention, the width d1 of the guide protrusion 3 is gradually increased in the direction closer to the first side 13. Therefore, during installation, the A-pillar guard plate flange 300 first contacts the guide protrusion 3 on the A-pillar sheet metal structure, and as it moves closer to the first side 13, the contact area between the A-pillar guard plate flange 300 and the guide protrusion 3 gradually increases, increasing stability and safety during movement.

[0035] In one feasible embodiment of the present invention, the guide protrusion 3 is an arc-shaped protrusion. Therefore, during installation, the A-pillar guard flange 300 first contacts the guide protrusion 3 on the A-pillar sheet metal structure, allowing the A-pillar guard flange 300 to move more smoothly along the arc surface to the first side 13, and then to the required installation position.

[0036] In some embodiments, the thickness of the guide protrusion 3 gradually decreases in the direction close to the first side 13, or the thickness of the guide protrusion 3 first increases and then decreases. This allows the A-pillar guard plate to be installed such that the flange 300 first contacts the thicker part of the guide protrusion 3, and then smoothly slides gradually along the curved surface to the first side 13.

[0037] In some embodiments, the guide protrusion 3 is disposed within a designated area d2, which is the region on the second segment 5-7 cm from its first side edge. This designated area is the region on the A-pillar sheet metal structure that is prone to interference with the A-pillar guard plate. Disposing the guide protrusion 3 in this region prone to interference can greatly reduce the difficulty of assembling the A-pillar guard plate.

[0038] It should be noted that the specific number of guide protrusions 3 in this embodiment of the invention is not limited. It can be 1, or 2, 3, 4, 5, 6, etc., arranged at intervals. It is only necessary to ensure that when the A-pillar guard plate is installed, the flange 300 of the A-pillar guard plate can first contact the guide protrusions 3 on the A-pillar sheet metal structure to reduce the assembly difficulty.

[0039] In some embodiments, the guide protrusion 3 is made of silicone or metal. When the guide protrusion 3 is made of metal, it can be an integral structure with the A-pillar main beam 1, or it can be a detachable structure. In the detachable structure, the guide protrusion 3 and the A-pillar main beam 1 can be connected by connectors, such as screw and nut assemblies. When the guide protrusion 3 is made of silicone, it can also be a detachable structure with the A-pillar main beam 1. In the detachable structure, the guide protrusion 3 and the A-pillar main beam 1 can be connected by connectors, such as screw and nut assemblies. Silicone-type guide protrusions have greater surface contact friction, preventing lateral wobbling when the A-pillar guard plate flange 300 contacts the guide protrusion 3 during A-pillar guard plate installation, thus improving installation stability and safety. Furthermore, the integral structure simplifies the assembly process, while the detachable structure allows for the combination of guide protrusions 3 made of different materials.

[0040] The present invention also proposes an A-pillar, including the A-pillar sheet metal structure and A-pillar guard plate as described above.

[0041] The present invention also proposes an automobile including the A-pillar as described above.

[0042] This invention provides a guide protrusion 3 on the second section 12 of the A-pillar main beam, near the first side 13. This first side is the side of the second section 12 of the A-pillar main beam closest to the supporting beam. Therefore, during the assembly of the A-pillar guard plate, the flange of the A-pillar guard plate will first contact the guide protrusion 3 on the A-pillar sheet metal structure. The guide protrusion 3 avoids interference between the flange and the first side of the A-pillar sheet metal structure, greatly reducing the difficulty of assembling the A-pillar guard plate without sacrificing the A-pillar's field of vision or affecting the overall aesthetics.

[0043] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made under the concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
