[0035] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0036] In this disclosure, unless otherwise stated, the directional terms up, down, left, right, front, and rear used refer to the up, down, left, right, front, and rear as defined under normal vehicle use conditions; for details, please refer to... Figure 3 As shown. The terms used, such as "first" and "second," are only for distinguishing one element from another and do not indicate order or importance. In addition, "multiple" in this application refers to more than two and includes two.

[0037] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0038] Reference Figures 1 to 3 As shown, this disclosure provides an A-pillar outer panel 52, which includes an A-pillar outer panel body 521, a front connector 522, and a rear connector 523.

[0039] The front connector 522 of the outer panel is connected to the front side of the outer panel body 521 of the A-pillar and is used to connect to the upper side of the lower reinforcing plate 2 of the A-pillar; the rear connector 523 of the outer panel is connected to the rear side of the outer panel body 521 of the A-pillar and is used to connect to the upper side of the B-pillar 4.

[0040] Among them, the A-pillar outer panel body 521, the front joint 522 of the outer panel, and the rear joint 523 of the outer panel are integrally formed.

[0041] In the above technical solution, the front connector 522 of the outer panel facilitates connection with the lower reinforcing plate 2 of the A-pillar; the rear connector 523 of the outer panel facilitates connection with the B-pillar 4. Furthermore, by designing the A-pillar outer panel body 521, the front connector 522, and the rear connector 523 as an integrally formed structure, the structural strength and rigidity of the A-pillar outer panel 52 can be effectively improved, thereby better dispersing the forces generated in collisions and other situations, and enhancing safety performance.

[0042] Optionally, refer to Figure 1 and Figure 2 As shown, the lower edge of the front connector 522 of the outer panel is smoothly connected to the lower edge of the outer panel body 521 of the A-pillar to define a first rounded corner R1. The front connector 522 of the outer panel includes a first connector edge 5221 away from the outer panel body 521 of the A-pillar, the first connector edge 5221 being used to connect with the upper edge of the lower reinforcing plate 2 of the A-pillar; wherein, the rear joint end of the first connector edge 5221 and the upper edge of the lower reinforcing plate 2 of the A-pillar is located below the first rounded corner R1.

[0043] In this embodiment, by smoothly connecting the lower edge of the front joint 522 of the outer panel to the lower edge of the A-pillar outer panel body 521 to form a first rounded corner R1, stress concentration points can be effectively dispersed, reducing the risk of cracks during impact or long-term use. This design helps to enhance the stability and durability of the A-pillar outer panel 52 structure.

[0044] Secondly, the presence of the first fillet R1 not only improves the appearance but also optimizes the stress distribution, so that when subjected to external impact, the force can be distributed more evenly on the material rather than concentrated at a certain point, thereby improving the impact resistance of the A-pillar outer panel 52, such as enhancing the ability to withstand small offset collisions.

[0045] In addition, the rear end of the joint between the first joint edge 5221 and the upper edge of the A-pillar reinforcement plate 2 is located below the first rounded corner R1, so that the joint position avoids the first rounded corner R1, thus preventing the joint position from passing through the first rounded corner R1 and damaging the structural strength of the first rounded corner R1, and reducing the risk of cracking at the first rounded corner R1.

[0046] In one implementation, reference is made to Figure 1 and Figure 3 As shown, the front joint 522 of the outer panel gradually expands in the direction away from the outer panel body 521 of the A-pillar, and the first joint edge 5221 extends downward at an angle from front to back.

[0047] In this embodiment, the expanding design increases the profile dimensions of the front side of the outer panel front joint 522, thereby enhancing its connection strength with the A-pillar under-reinforcing plate 2. Secondly, the expanding shape also reinforces the structural strength of the outer panel front joint 522. Furthermore, the downward sloping design of the first joint edge 5221 from front to back guides the load along a more natural path, reducing stress concentration points and further improving the overall stability and durability of the structure.

[0048] Optionally, the edge 5221 of the first joint is connected to the upper edge of the lower reinforcing plate 2 of the A-pillar by laser welding.

[0049] In this embodiment, laser welding not only enhances the connection strength between the A-pillar outer panel 52 and the A-pillar lower reinforcing plate 2, but also eliminates the need for additional welding filler, effectively reducing the weight of the structural components. Furthermore, laser welding produces smooth, uniform weld seams, improving aesthetics.

[0050] In another embodiment, refer to Figure 1 and Figure 3As shown, the rear connector 523 of the outer panel is connected to the lower edge of the outer panel body 521 of the A-pillar and extends downward; the front edge of the rear connector 523 of the outer panel is smoothly connected to the lower edge of the outer panel body 521 of the A-pillar to define a second rounded corner R2; the rear connector 523 of the outer panel includes a second connector edge 5231 away from the outer panel body 521 of the A-pillar, and the second connector edge 5231 is connected to the upper edge of the outer panel 42 of the B-pillar; wherein, the front joint end of the second connector edge 5231 and the upper edge of the outer panel 42 of the B-pillar is located below the second rounded corner R2.

[0051] In this embodiment, firstly, by designing a smooth transition second fillet R2 between the lower edge of the A-pillar outer panel body 521 and the rear joint 523 of the outer panel, the stress concentration point can be effectively dispersed, reducing the risk of material fatigue or fracture caused by stress concentration, thereby improving the stability and durability of the structure.

[0052] Secondly, the rear panel connector 523 is connected to the lower edge of the A-pillar outer panel body 521 and extends downward. The downwardly extending rear panel connector 523 can effectively transmit the impact force from above, ensuring that the force from the A-pillar outer panel 52 is transmitted to the B-pillar outer panel 42 through the rear panel connector 523.

[0053] In addition, the front joint end of the second joint edge 5231 and the upper edge of the B-pillar outer panel 42 is located below the second rounded corner R2, so that the position of the joint avoids the second rounded corner R2, and avoids the position of the joint passing through the second rounded corner R2 and damaging the structural strength of the second rounded corner R2, thereby reducing the risk of cracking at the second rounded corner R2.

[0054] Optionally, the edge 5231 of the second joint is connected to the upper edge of the outer panel 42 of the B-pillar by laser welding.

[0055] In this embodiment, laser welding not only enhances the connection strength between the A-pillar outer panel 52 and the B-pillar outer panel 42, but also eliminates the need for additional welding filler, effectively reducing the weight of the structural components. Furthermore, laser welding produces smooth, uniform weld seams, improving aesthetics.

[0056] Optionally, refer to Figure 3 As shown, the A-pillar outer panel 52 also includes an outer panel middle side connector 524, which is connected to the middle side of the A-pillar outer panel body 521 in the front-rear direction, and the outer panel middle side connector 524 is used to connect with the front crossbeam 6 of the roof.

[0057] In this embodiment, by providing a middle-side connector 524 in the outer panel, the connection between the A-pillar outer panel body 521 and the front roof crossbeam 6 can be strengthened. Furthermore, the middle-side connector 524 can effectively disperse the force from the front roof crossbeam 6, preventing excessive load on a single area and reducing the risk of localized deformation. Through this middle-side connector 524, the force on the front roof crossbeam 6 can be transferred to the A-pillar outer panel 52, which can then transfer the force to the lower A-pillar reinforcing plate 2 and the B-pillar 4, effectively dispersing the force.

[0058] Optionally, the outer panel middle joint 524, the A-pillar outer panel body 521, the outer panel front joint 522, and the outer panel rear joint 523 are integrally formed. This can effectively improve the structural strength and rigidity of the A-pillar outer panel 52, thereby better dispersing the forces generated in collisions and other situations, and improving safety performance.

[0059] In addition, regarding the thickness of the outer panel 52 of the A-pillar, the thickness of the plate material of the middle side joint 524 of the outer panel can be greater than the thickness of the plate beam in other areas; for example, the thickness of the plate material of the middle side joint 524 of the outer panel can be 1.8mm, and the thickness of the plate material in other areas of the outer panel 52 of the A-pillar can be 1.4mm, but this disclosure does not limit the thickness of the plate material of the outer panel 52 of the A-pillar.

[0060] In one implementation, reference is made to Figure 3 As shown, the outer panel middle side connector 524 is connected to the side of the A-pillar outer panel body 521 that is close to the interior of the vehicle in the left and right direction. The outer panel middle side connector 524 protrudes from the A-pillar outer panel body 521 in the left and right direction and is used to extend toward the front crossbeam 6 of the roof.

[0061] In this embodiment, firstly, by making the middle side joint 524 of the outer panel protrude from the A-pillar outer panel body 521 in the left-right direction and extend toward the front crossbeam 6 of the roof, the rigidity and stability of the connection between the front crossbeam 6 of the roof and the A-pillar 5 can be increased.

[0062] Optionally, the size of the outer panel mid-side connector 524 protruding from the A-pillar outer panel body in the left-right direction is between 50mm and 80mm. For example, the size of the outer panel mid-side connector 524 protruding from the A-pillar outer panel body in the left-right direction can be 50mm; or, the size of the outer panel mid-side connector 524 protruding from the A-pillar outer panel body in the left-right direction can be 70mm; or, the size of the outer panel mid-side connector 524 protruding from the A-pillar outer panel body in the left-right direction can be 80mm; however, this disclosure does not limit the size of the outer panel mid-side connector 524 protruding from the A-pillar outer panel body in the left-right direction.

[0063] This disclosure also provides an A-pillar 5, which includes the aforementioned A-pillar outer panel 52.

[0064] This disclosure also provides a vehicle body structure including the aforementioned A-pillar 5.

[0065] This disclosure also provides a vehicle that includes the aforementioned body structure.
