[0027] Unless otherwise defined, all technical and scientific terms used in the specification of the present application have the same meaning as commonly understood by one skilled in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application. The term "and / or" used in the specification of the present application includes any and all combinations of one or more related listed items.

[0028] As shown in Figures 1-4 , the present application discloses an A-pillar structure. The A-pillar structure is applied to a vehicle, such as an automobile. As shown in Figures 1-3 , the vehicle includes an A-pillar structure, a B-pillar, a front windshield 5 and a door 9 located behind the front windshield 5, and the side edge of the front windshield 5 is connected to the front part of the door 9 through the A-pillar structure.

[0029] As shown in Figure 2 and Figure 3 , the above-mentioned A-pillar structure includes an A-pillar inner panel 1, a side wall outer panel 2 and a hot gas expansion tube 3. The side wall outer panel 2 is connected to the outer side of the A-pillar inner panel 1, and a cavity 4 is formed between the A-pillar inner panel 1 and the side wall outer panel 2. The hot gas expansion tube 3 is arranged in the cavity 4, and the hot gas expansion tube 3 extends along the length direction of the A-pillar inner panel 1, and the hot gas expansion tube 3 is connected to the A-pillar inner panel 1. Part of the above-mentioned side wall outer panel 2 overlaps the side wall of the hot gas expansion tube 3. Obviously, a tube cavity is defined in the above-mentioned hot gas expansion tube 3.

[0030] It is understandable that the hot air expansion tube 3 is located in the cavity 4 formed by the inner A-pillar panel 1 and the outer side panel 2, and partially overlaps the outer side panel 2 with the hot air expansion tube 3. Upon impact, the presence of the hot air expansion tube 3 increases the bending resistance of the A-pillar structure due to its internal cavity, improving vehicle safety in small offset collisions and thus ensuring occupant safety. Furthermore, it enhances the strength and deformation resistance at the overlap point between the outer side panel 2 and the hot air expansion tube 3. Additionally, by placing the hot air expansion tube 3 solely within the cavity 4, the weight of the A-pillar structure is reduced, and the space occupied within the cavity 4 is minimized, effectively improving the bending resistance of the A-pillar structure.

[0031] In one embodiment, a boss 21 is formed on the side of the outer side panel 2 facing the hot gas expansion tube 3. In this embodiment, as... Figure 3 As shown, a portion of the outer side panel 2 protrudes towards the hot gas expansion tube 3 to form a boss 21, which overlaps the side wall of the hot gas expansion tube 3. The presence of the aforementioned boss 21 allows the outer side panel 2 to better overlap the hot gas expansion tube 3.

[0032] In other embodiments, the sidewall of the hot gas expansion tube 3 forms a recessed groove in which the boss 21 is located. In this embodiment, as... Figure 3 As shown, the surface of the boss 21 facing the hot gas expansion tube 3 is defined as the platform surface 211. The side wall of the hot gas expansion tube 3 has a plane 31 that fits against the platform surface 211. It can be understood that the presence of the plane 31 increases the overlap area between the hot gas expansion tube 3 and the platform surface 211, thereby improving the strength and deformation resistance at the overlap area between the side outer plate 2 and the hot gas expansion tube 3.

[0033] In one embodiment, the tabletop 211 and the hot air expansion tube 3 can be connected by screws. In this embodiment, the tabletop 211 is fixed to the plane 31 by welding. It can be understood that welding not only facilitates the connection between the tabletop 211 and the hot air expansion tube 3, but also improves the connection strength between the hot air expansion tube 3 and the outer side panel 2.

[0034] Along the longitudinal direction of the vehicle, at least a portion of the boss 21 is located in front of the hot air expansion tube 3. In other embodiments, a portion of the boss 21 is located in front of the hot air expansion tube 3. In this embodiment, as... Figure 3 As shown, the boss 21 is located in front of the hot air expansion tube 3. Furthermore, a groove 212 for accommodating the side of the windshield 5 is formed on the front side of the boss 21. It can be understood that a portion of the boss 21 overlaps with the hot air expansion tube 3, and the groove 212 on the front side of the boss 21 allows the side of the windshield 5 to rest within it. Therefore, the boss 21 is formed to facilitate both connection with the hot air expansion tube 3 and accommodation of the side of the windshield 5.

[0035] In this embodiment, a sealing connection is formed between the side edge of the outer side panel 2 and the corresponding edge of the inner A-pillar panel 1 by a sealing member 6, which is located behind the hot air expansion tube 3. It is understood that the presence of the sealing member 6 ensures a tight seal between the outer side panel 2 and the inner A-pillar panel 1, serving a waterproof and dustproof function. In this embodiment, the sealing member 6 is a sealing strip.

[0036] In one embodiment, the hot air expansion tube 3 is welded and fixed to the inner plate 1 of the A-pillar. In another embodiment, the hot air expansion tube 3 is connected to the inner plate 1 of the A-pillar via a connecting structure 7. Figure 3 As shown, the wall surface of the inner plate 1 of the A-pillar facing the hot air expansion tube 3 is defined as the first wall surface 11, and the first wall surface 11 is provided with a mounting base 12 extending towards the hot air expansion tube 3. The aforementioned connection structure 7 includes a connector 71 mounted on the mounting base 12, and the hot air expansion tube 3 has a mounting hole that constrains the connector 71. The connector 71 is a screw, bolt, or a connecting post that can be detachably mounted on the mounting base 12. In another embodiment, the mounting base 12 and the hot air expansion tube 3 have corresponding connecting holes for the connector 71 to be constrained therein. In other embodiments, the connection structure 7 is a snap-fit ​​structure.

[0037] It is understandable that the hot air expansion tube 3 is fixedly connected to the outer side panel 2 by welding and to the inner A-pillar panel 1 by the connecting structure 7. This avoids the problem of low strength of the hot air expansion tube 3 caused by using multiple mounting plates to connect the hot air expansion tube 3 to the roof. In other words, it avoids the problem of low strength of the hot air expansion tube 3 caused by too many mounting points.

[0038] In this embodiment, column B (not shown) is located behind the hot gas expansion tube 3, such as... Figure 4 As shown, the first end of the aforementioned hot air expansion tube 3 is provided with a first connector 81 for connecting to the B-pillar of the vehicle, and the second end of the hot air expansion tube 3 is provided with a second connector 82 for connecting to the outer side panel 2. The first connector 81 is a connector formed of semi-solid cast aluminum. It can be understood that the aforementioned A-pillar structure can be used in vehicles with triangular window structures, which use sliding doors. The semi-solid cast aluminum form of the first connector 81 simplifies the welding process, facilitates the connection between the B-pillar and the hot air expansion tube 3, and reduces the weight of the vehicle body.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above-described embodiments are merely illustrative of several embodiments of the present application, which are described in more detail and in a specific manner, but should not be construed as limiting the scope of the patent application. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
