[0046] 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.

[0047] 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 6 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 two or more and includes two.

[0048] 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.

[0049] Reference Figures 1 to 7 As shown, this disclosure provides a B-pillar inner panel 41, which extends vertically and includes a B-pillar inner panel body 411. The B-pillar inner panel body 411 is arranged facing the vehicle interior in the left-right direction. An upper mounting portion 412 is provided on the upper side of the B-pillar inner panel body 411, and a middle mounting portion 413 is provided on the middle side of the B-pillar inner panel body 411 in the vertical direction. The upper mounting portion 412 and the middle mounting portion 413 are used to install a B-pillar interior trim panel (not shown). The upper mounting portion 412 includes an upper mounting surface 4120, and the middle mounting portion 413 includes a middle mounting surface 4130. The upper mounting surface 4120 and the middle mounting surface 4130 are used to abut against the B-pillar interior trim panel, and the included angle between the upper mounting surface 4120 and the middle mounting surface 4130 is an acute angle.

[0050] In the above technical solution, an upper mounting portion 412 is provided on the upper side of the B-pillar inner panel body 411, and a middle mounting portion 413 is provided on the middle side of the B-pillar inner panel body 411 in the vertical direction. These upper mounting portions 412 and middle mounting portions 413 facilitate the installation of the B-pillar inner trim panel, ensuring the stability of the B-pillar inner trim panel installation. Secondly, by making the included angle between the upper mounting surface 4120 and the middle mounting surface 4130 an acute angle, it facilitates the fitting of the B-pillar inner trim panel to the B-pillar inner panel body 411, improving assembly convenience. Furthermore, it reduces localized stress, enhances the B-pillar inner panel 41's resistance to impact forces in the vertical direction, and mitigates the risk of deformation or breakage of the B-pillar inner panel 411.

[0051] In one embodiment, the included angle between the upper mounting surface 4120 and the middle mounting surface 4130 is no greater than 23 degrees, which improves the ease of assembly and the ability to resist impact. For example, the included angle can be 10 degrees or 20 degrees, etc., and this disclosure does not limit the specific angle.

[0052] In one implementation, reference Figure 1 and Figure 2 As shown, the upper mounting portion 412 includes a mounting groove 4121 and an upper mounting hole 4122. The bottom surface of the mounting groove 4121 is constructed as an upper mounting surface 4120, and the upper mounting hole 4122 is formed on the upper mounting surface 4120.

[0053] In this embodiment, the bottom surface of the mounting groove 4121 is constructed as an upper mounting surface 4120, which facilitates contact with the B-pillar interior trim panel and improves assembly stability; the upper mounting hole 4122 facilitates the connection of fasteners to the B-pillar interior trim panel and the B-pillar interior panel body 411. However, this disclosure does not limit the specific structure of the upper mounting part 412.

[0054] In another embodiment, refer to Figure 1 and Figure 3 As shown, the middle mounting portion 413 includes a mounting protrusion 4131 and a middle mounting hole 4132. The protruding surface of the mounting protrusion 4131 is constructed as a middle mounting surface 4130, and the middle mounting hole 4132 is formed on the middle mounting surface 4130.

[0055] In this embodiment, the protruding surface of the mounting protrusion 4131 is the side of the mounting protrusion 4131 away from the B-pillar inner panel 411. This protruding surface facilitates contact with the B-pillar inner trim panel, improving assembly stability. In addition, the center mounting hole 4132 facilitates the connection of fasteners between the B-pillar inner trim panel and the B-pillar inner panel body 411. However, this disclosure does not limit the specific structure of the center mounting portion 413.

[0056] In addition, the B-pillar inner panel body 411 is curved from its upper region to its middle region. That is, in the direction from top to bottom, the B-pillar inner panel body 411 is gradually curved outward in the left and right direction. If the upper mounting part 412 and the middle mounting part 413 are not provided, the assembly of the B-pillar inner trim panel will be more difficult due to the curved shape of the B-pillar inner panel body 411.

[0057] By setting the aforementioned mounting protrusion 4131, which protrudes into the vehicle in the left and right direction, the angle between the middle mounting surface 4130 and the upper mounting surface 4120 can be effectively reduced, facilitating the assembly of the B-pillar interior trim panel.

[0058] In addition, the recess depth of the aforementioned mounting groove 4121 can also be effectively reduced, reducing the risk that the excessive recess depth of the mounting groove 4121 will affect the strength of the upper part of the B-pillar inner panel body 411, that is, reducing the impact on the strength of the upper part of the B-pillar inner panel 41, thereby reducing stress concentration and cracking problems at this location, and improving the ability of the B-pillar inner panel 41 to resist impact in the vertical direction.

[0059] Optionally, the center mounting hole 4132 is constructed as an elongated hole extending in the vertical direction. That is, the extension direction of the elongated hole is the same as the vertical direction of the B-pillar inner panel 41. When the B-pillar inner panel 41 is subjected to vertical impact force, the elongated hole is less likely to deform, thus ensuring the strength of the B-pillar inner panel 41.

[0060] In addition, the vertical dimension of the center mounting hole 4132 is no greater than 24.5mm. This reduces the impact of an excessively large center mounting hole 4132 on the strength of the center area of ​​the B-pillar inner panel 411, ensuring that the center area of ​​the B-pillar inner panel 411 has sufficient structural strength to withstand the force transmitted from the upper end.

[0061] Optionally, refer to Figure 1 As shown, the B-pillar inner panel body 411 has two inner panel protruding ribs 414 protruding inward toward the vehicle interior; the inner panel protruding ribs 414 extend in the vertical direction, and the two inner panel protruding ribs 414 are spaced apart in the front-rear direction; two middle side mounting parts 413 are provided, and the two middle side mounting parts 413 are respectively provided on the side of the two inner panel protruding ribs 414 away from the B-pillar inner panel body 411.

[0062] In this embodiment, by providing the aforementioned inner plate protrusions 414, the structural strength and rigidity of the B-pillar inner plate body 411 can be enhanced, thereby improving its ability to withstand forces in the vertical direction. In addition, the two inner plate protrusions 414 are spaced apart in the front-rear direction, which can also improve the torsional resistance of the B-pillar inner plate body 411 and reduce the risk of torsional deformation of the B-pillar inner plate body 411.

[0063] In addition, the two middle side mounting parts 413 are respectively set on the side of the two inner panel protrusions 414 away from the B-pillar inner panel body 411. By utilizing the protruding characteristics of the inner panel protrusions 414 themselves, the difficulty of the B-pillar inner decorative panel is effectively reduced.

[0064] Optionally, refer to Figure 1 As shown, the inner panel 41 of the B-pillar has a retractor opening 415 for installing a retractor. The retractor opening 415 is located in the lower area of ​​the inner panel body 411 of the B-pillar and is located between two inner panel protrusions 414.

[0065] In this embodiment, the retractor opening 415 is positioned between the two inner plate ribs 414, which fully utilizes the space between the two inner plate ribs 414 and improves space utilization. Furthermore, although the retractor opening 415 is provided, by placing it between the two inner plate ribs 414 that provide additional strength and rigidity, the impact on the overall structural integrity and strength of the B-pillar inner plate 41 is minimized. This ensures that even after the retractor is installed, the B-pillar inner plate 41 can still maintain its necessary load-bearing capacity and impact resistance.

[0066] In other embodiments, refer to Figure 1 As shown, the retractor opening 415 includes two opening side edges 4151 arranged opposite each other in the front-back direction, and the inner plate protrusion rib 414 includes a protrusion rib edge 4141 that is opposite to the retractor opening 415 in the front-back direction; wherein, the dimension between the opening side edge 4151 and the protrusion rib edge 4141 of the adjacent inner plate protrusion rib 414 is not less than 15mm.

[0067] In this embodiment, firstly, by ensuring a distance of at least 15 mm between the edge 4151 of the opening and the edge 4141 of the raised rib, the structural weakening caused by the opening 415 of the retractor can be effectively reduced. This distance ensures that even on the side of the retractor opening 415, the inner panel of the B-pillar can maintain sufficient structural strength and rigidity, thereby improving overall safety. Furthermore, the larger edge spacing helps to disperse the stress acting around the retractor opening 415, reducing the risk of fatigue damage due to repeated loads (such as vibrations during vehicle operation).

[0068] Optionally, the inner panel protrusion 414 protrudes from the inner panel body 411 of the B-pillar by an amount between 10 mm and 15 mm. For example, the inner panel protrusion 414 protrudes from the inner panel body 411 of the B-pillar by an amount of 10 mm; or, the inner panel protrusion 414 protrudes from the inner panel body 411 of the B-pillar by an amount of 12 mm; or, the inner panel protrusion 414 protrudes from the inner panel body 411 of the B-pillar by an amount of 15 mm. This disclosure does not limit the specific dimensions.

[0069] In another implementation, refer to Figure 4 and Figure 5 As shown, the B-pillar inner panel 41 also includes a B-pillar inner side panel 416 extending in the vertical direction. The B-pillar inner side panel 416 is connected to the B-pillar inner panel body 411 and extends outward in the left and right direction. The side of the B-pillar inner side panel 416 away from the B-pillar inner panel body 411 is used to connect with the B-pillar outer panel 42.

[0070] In this embodiment, by connecting the inner B-pillar panel 416 to the inner B-pillar panel body 411 and extending it outward in the left-right direction to connect it with the outer B-pillar panel 42, a composite structure is formed, further improving the compressive and bending resistance of the inner B-pillar panel. Furthermore, adding the inner B-pillar panel 416 and connecting it to the outer B-pillar panel 42 can effectively absorb and disperse impact forces from the sides, improving safety performance.

[0071] Optionally, refer to Figure 4 and Figure 5 As shown, a side panel outline edge 4161 is formed on the side of the inner side panel 416 away from the inner side panel body 411 of the B-pillar. The side panel outline edge 4161 is used to connect with the outer side panel 42 of the B-pillar. The side panel outline edge 4161 includes a first outline segment 4162 and a second outline segment 4163 extending in the vertical direction. The first outline segment 4162 is connected above the second outline segment 4163. In the vertical direction, the first outline segment 4162 gradually extends outward in the horizontal direction, and the second outline segment 4163 gradually extends inward in the horizontal direction. The connection position of the first outline segment 4162 and the second outline segment 4163 is at the same height as the middle side mounting part 413.

[0072] In this embodiment, firstly, the design of the first contour segment 4162 and the second contour segment 4163 allows the side panel contour edge 4161 to extend in different directions at different heights. This helps to increase the connection strength and rigidity between the inner side panel 416 and the outer side panel 42 of the B-pillar. In particular, the contour variation formed in the vertical direction can better disperse stress and reduce local stress concentration. Secondly, the connection position of the first contour segment 4162 and the second contour segment 4163 is at the same height as the middle side mounting part 413. This design ensures structural reinforcement at the structural bend, providing a stronger support structure and improving the structural strength at the local bend.

[0073] Optionally, refer to Figure 5 As shown, there are two inner side panels 416 of the B-pillar. The two inner side panels 416 are arranged opposite each other and spaced apart in the front-rear direction. The two inner side panels 416 and the inner panel body 411 of the B-pillar together form the inner panel groove 410.

[0074] By incorporating two inner side panels 416 of the B-pillar and arranging them at intervals in the front-rear direction, the overall structural strength and rigidity of the inner panel 41 of the B-pillar can be significantly improved. This design helps to form a "frame" structure, enabling the inner panel 41 of the B-pillar to provide stronger support in different directions.

[0075] The two opposing B-pillar inner side panels 416 and the B-pillar inner panel body 411 form an effective force transmission path. When a vehicle collides, especially in a side collision, the impact force can be more evenly distributed throughout the B-pillar 4 through this frame structure, reducing the problem of local stress concentration.

[0076] In addition, the aforementioned inner plate groove 410 can provide installation space for other structural components, thereby improving space utilization.

[0077] This disclosure also provides a B-pillar 4, which includes the aforementioned inner B-pillar panel 41.

[0078] Additionally, refer to Figure 6 As shown, this disclosure also provides a vehicle body structure, which further includes a side sill 8 and the aforementioned B-pillar 4. The B-pillar 4 also includes a B-pillar outer panel 42 connected to the B-pillar inner panel 41. The side sill 8 includes a sill top panel 81 and a sill side panel 82 connected to each other. The B-pillar outer panel 42 includes a B-pillar outer panel body 421, a first overlapping plate 422, and a second overlapping plate 423. The first overlapping plate 422 and the second overlapping plate 423 are connected to the lower part of the B-pillar outer panel body 421. The first overlapping plate 422 overlaps the outer surface of the sill top panel 81, and the second overlapping plate 423 overlaps the outer surface of the sill side panel 82.

[0079] In this technical solution, the first overlapping plate 422 and the second overlapping plate 423 overlap the outer surfaces of the sill top plate 81 and the sill side plate 82, respectively. This design allows the B-pillar outer plate 42 to form a tight and firm connection with the side sill 8. This not only enhances the structural strength of the B-pillar 4 itself, but also improves the overall rigidity and stability of the entire vehicle body structure; in particular, it can effectively transfer the forces borne by the B-pillar 4 in the vertical direction to the lower side sill 8.

[0080] Furthermore, by overlapping the first lap plate 422 and the second lap plate 423 at different locations (sill top plate 81 and sill side plate 82), the force can be effectively dispersed. Especially in the event of a collision, this design helps to disperse the impact force and reduce local stress concentration.

[0081] Optionally, refer to Figure 6 and Figure 7As shown, the outer side of the lower part of the B-pillar outer panel body 421 is recessed in the direction of the vehicle interior to form an outer panel groove 4210; the outer panel groove 4210 includes a groove bottom plate 4211 and a groove side plate 4212, the groove side plate 4212 connects the groove bottom plate 4211 and the second overlapping plate 423, and the groove side plate 4212 overlaps the outer surface of the sill top plate 81.

[0082] In this embodiment, the recessed bottom plate 4211 and the recessed side plate 4212 together form an effective force transmission path. Since the recessed side plate 4212 overlaps the outer surface of the sill top plate 81, the impact force from above can be transmitted to the sill top plate 81 through the recessed bottom plate 4211 and the recessed side plate 4212 in sequence, that is, to the side sill 8. This more effectively transmits the force borne by the B-pillar 4 in the vertical direction to the lower side sill 8, reducing the problem of stress concentration.

[0083] This disclosure also provides a vehicle that includes the aforementioned body structure.
