Description

Technical Field

[0001] This application relates to the field of vehicle body structure technology, specifically to a rear side panel assembly, and also to a vehicle. Background Technology

[0002] The C-pillar is a key supporting structure for the rear side panel assembly, connecting the roof, rear side panel, rear fender, and rear door latch area. In related technologies, the rear side panel assembly mainly improves local bending stiffness through dispersed reinforcing ribs or local reinforcing plates. However, these structures cannot form a continuous force transmission path in side collisions, resulting in poor overall side collision performance. Energy absorption is mainly achieved through large structural deformation, leading to a large intrusion into the passenger compartment. It also results in material redundancy in some areas, which is not conducive to weight reduction.

[0003] In addition, the wiring harness channels of the rear side assembly usually require additional brackets, which increases the number of parts and assembly complexity. Utility Model Content

Detailed Implementation

[0025] The embodiments of this application will be described below. It should be noted that, in order to provide a concise description of these embodiments, this specification cannot provide a detailed description of all features of the actual embodiments. It should be understood that, in the actual implementation of any embodiment, changes may occur from one embodiment to another to achieve specific objectives. Furthermore, it is also understood that, although the efforts made in this development process may be complex and lengthy, for those skilled in the art related to the content of this application, some design, manufacturing, or production modifications based on the technical content disclosed in this application are merely conventional technical means and should not be construed as insufficient content of this application.

[0026] This application provides a vehicle including a rear side panel assembly. The side panel is an important component of a car body, consisting of an outer side panel and an inner side panel. The rear side panel assembly is the rear structure of the side panel. The C-pillar is a key supporting structure of the rear side panel assembly, connecting the roof, rear side panel, rear fender, rear door latch area, etc. It provides mounting for the rear seat belts and rear door latches, and serves as a supporting pillar for the rear window glass or rear door; it provides body rigidity and torsional rigidity, ensuring side collision safety. For example, the vehicle can be a sedan or a commercial vehicle.

[0027] Please refer to Figures 1-6 In some embodiments, the rear side panel assembly includes a C-pillar inner panel 1 extending along the vehicle height direction. The top end of the C-pillar inner panel 1 is connected to the roof longitudinal beam, and the bottom end of the C-pillar inner panel 1 is connected to the rear floor longitudinal beam. A first reinforcing protrusion protruding inward along the vehicle width direction is provided on the edge of the C-pillar inner panel 1 near the door opening. The first reinforcing protrusion extends from the top end of the C-pillar inner panel 1 to the bottom end. A C-pillar outer panel 9 is provided on the edge of the C-pillar outer panel 9 near the door opening. A second reinforcing protrusion protruding outward along the vehicle width direction is provided on the edge of the C-pillar outer panel 9. The second reinforcing protrusion is arranged opposite to the first reinforcing protrusion and cooperates to form a collision energy absorption cavity b.

[0028] It should be noted that the vehicle length direction refers to the longitudinal direction of the vehicle, that is, the vehicle X direction; the vehicle width direction refers to the lateral direction of the vehicle, that is, the vehicle Y direction; and the vehicle height direction refers to the vertical direction of the vehicle, that is, the vehicle Z direction.

[0029] In the rear side panel assembly provided in this application embodiment, a first reinforcing protrusion is used as a reinforcing rib on the inner C-pillar panel 1, extending from the roof longitudinal beam connection area around the door opening to the rear floor longitudinal beam connection area; a second reinforcing protrusion is used as a reinforcing rib on the outer C-pillar panel 9, extending from the roof longitudinal beam connection area around the door opening to the rear floor longitudinal beam connection area; the first reinforcing protrusion and the second reinforcing protrusion are arranged opposite to each other and cooperate to form a continuous closed collision energy absorption cavity b that extends from the top end to the bottom end of the inner C-pillar panel 1 around the edge of the door opening, which can strengthen the door frame structure and form a continuous core force transmission path under multiple working conditions (including side collision, top pressure, and torsion) between the roof longitudinal beam and the rear floor longitudinal beam, which can improve the overall bending stiffness of the door opening edge, thereby improving the side collision performance of the whole vehicle and reducing the intrusion of the passenger compartment.

[0030] Furthermore, the collision energy absorption cavity b of this application can undergo collapse deformation on both sides, resulting in a better energy absorption effect. This can reduce the redundancy of reinforcing materials in other areas and is beneficial for weight reduction.

[0031] Specifically, compared to related technologies that improve local bending stiffness through dispersed reinforcing ribs, the embodiments of this application can increase bending stiffness by approximately 35% and torsional stiffness by approximately 25% under the same weight. Compared to related technologies that improve local bending stiffness through local reinforcing plates, the embodiments of this application can reduce the rear intrusion of the B-pillar by 60mm in side impacts (such as IIHS side pole impacts), significantly improving the integrity of the passenger compartment; and increase the roof crush strength by approximately 43%. At the same time, it can reduce the reinforcing structure in non-core force transmission paths, achieving a lightweight effect while meeting the same performance requirements, reducing weight by approximately 15%, which can effectively reduce the energy consumption of the whole vehicle and facilitate assembly.

[0032] Please refer to Figures 5-6 In some embodiments, the rear side panel assembly includes a rear wheel arch outer panel 4 and a D-pillar inner panel upper plate 7, which are integrated with the C-pillar inner panel 1 into a single unit. This configuration, with the single unit serving as an integrated mounting platform, integrates the C-pillar inner panel 1, the rear wheel arch outer panel 4, and the D-pillar inner panel upper plate 7. This improves the integration of the rear side panel assembly, reduces the number of parts, thereby reducing the number of welding overlaps, simplifying the assembly process, shortening assembly time by 60%, and reducing manufacturing costs by approximately 48%. Simultaneously, it reduces vibration transmission caused by panel overlaps, lowers road noise in specific frequency bands, and optimizes NVH performance. Furthermore, the single unit exhibits better stiffness along the vehicle height direction, improving the overall vehicle's side impact performance.

[0033] Please refer to Figure 4In some embodiments, the integrated plate has a wire harness mounting groove 11; in this way, the wire harness mounting groove 11 can be stamped into the integrated plate as a wire harness mounting point for embedding and guiding the wire harness without the need for additional brackets; the number of parts is reduced, the assembly process can be simplified, and production efficiency and consistency can be improved.

[0034] In some embodiments, the area of ​​the triangular window a formed by the integral panel is provided with a reinforcing structure. For example... Figure 1 As shown, the reinforced structure in the triangular window area a of the integrated panel forms a continuous auxiliary force transmission path under multiple conditions (including side impact, roof crush, and torsion), which can improve the overall bending stiffness of the rear side panel assembly, further improve the side impact performance of the vehicle, and thus reduce the intrusion of the passenger compartment. This auxiliary force transmission path, combined with the core force transmission path formed by the collision energy absorption cavity b, can create a clear and efficient multi-path force transmission mechanism and an optimized energy absorption structure, more effectively dispersing and absorbing energy during a collision, providing more reliable protection for occupants and improving safety. Optionally, the reinforced structure can be an energy absorption box formed by two protrusions, a reinforced flange structure, or a thickened area, as long as it can achieve the reinforcement of the triangular window area a.

[0035] In some embodiments, the inner panel 1 of the C-pillar has a first flange on the side near the door opening, and the first flange is connected to the outer panel 9 of the C-pillar; the outer panel 9 of the C-pillar has a second flange on the side near the door opening and a third flange on the side away from the door opening, and the third flange is connected to the side of the inner panel 1 of the C-pillar away from the door opening. Figures 2-3 As shown, the inner C-pillar panel 1 and the outer C-pillar panel 9 form a multi-layered flange structure near the edge of the door opening. Together with the collision energy absorption cavity b formed by the first reinforcing protrusion and the second reinforcing protrusion, they can form a surrounding door frame reinforcement structure, which significantly improves local stiffness and bending resistance.

[0036] In some embodiments, the top end of the C-pillar inner panel 1 is provided with a fourth flange 13 connected to the roof longitudinal beam; the bottom end of the C-pillar inner panel 1 is provided with a fifth flange connected to the rear floor longitudinal beam. For example... Figure 6 As shown, the inner panel 1 of the C-pillar is connected to the roof longitudinal beam and the rear floor longitudinal beam by a flange. The shape and size of the flange at the connection point have been optimized to improve the connection rigidity and welding convenience.

[0037] like Figure 1 and Figure 4As shown, in some embodiments, the rear side panel assembly further includes: a CD pillar connecting plate 5 disposed on the integrated panel, the CD pillar connecting plate 5 being disposed along the vehicle length direction and connected between the C pillar inner panel 1 and the upper plate 7 of the D pillar inner panel; a lower plate 6 of the D pillar inner panel, disposed on the lower side of the upper plate 7 of the D pillar inner panel; an upper reinforcing plate 8 of the D pillar, disposed on the upper plate 7 of the D pillar inner panel and connected to the lower plate 6 of the D pillar inner panel; a lower support plate 3 of the C pillar, disposed on the lower side of the C pillar inner panel 1; and a seat belt retractor fixing plate 2, disposed on the C pillar inner panel 1. This arrangement improves the rigidity of the rear side panel assembly along the vehicle length direction through the CD pillar connecting plate 5, enhances the strength of the D pillar inner panel through the lower plate 6 and the upper reinforcing plate 8, and enhances the strength of the C pillar inner panel 1 through the lower support plate 3; thereby improving the overall collision performance of the rear side panel assembly; and simultaneously, the seat belt retractor is mounted on the seat belt retractor fixing plate 2 on the C pillar inner panel 1, improving the stability of the seat belt retractor.

[0038] Optionally, the rear side assembly may also include a C-ring 10 to improve connection rigidity and welding ease.

[0039] In some embodiments, a first weight-reducing hole 12 may be provided in the area of ​​the integrated panel away from the edge of the doorway; a second weight-reducing hole 51 may be provided on the CD column connecting plate 5. For example... Figures 4-5 As shown, weight-reducing holes are provided in non-critical force-transmitting areas, which can reduce weight without affecting strength, thus facilitating lightweighting. There can be one or more first weight-reducing holes 12 and second weight-reducing holes 51, which can be elliptical, circular, or waist-shaped. Optionally, flanges or rolled edges can be designed at the edges of the first weight-reducing holes 12 and / or the second weight-reducing holes 51 to improve rigidity and avoid stress concentration.

[0040] In some embodiments, the inner C-pillar panel 1 is provided with mounting holes for installing the rear door latch, and a locally thickened area is provided near the mounting holes. Thus, the integrated panel has a first set of mounting holes for installing the rear door latch and a second set of mounting holes for installing the seatbelt retractor. The locally thickened area on the inner side of the integrated panel ensures sufficient strength and rigidity when bearing the door weight and impact loads. The integrated panel is connected to the seatbelt retractor fixing plate 2 via a smooth transition area, facilitating stress diffusion and stamping. This design integrates the installation functions, previously scattered across multiple parts, into a single structure, reducing the number of parts and welds, and improving the rigidity and positional accuracy of the mounting points.

[0041] In some embodiments, the integrated plate is a stamped part. In this way, the rear wheel arch outer plate 4, the inner plate 7 of the D-pillar, the inner plate 1 of the C-pillar, and the wiring harness mounting groove 11 and the inner plate 7 of the D-pillar can be formed by the bosses, grooves or platforms formed by stamping, forming a highly integrated integrated plate, which can reduce parts and solder joints, improve assembly efficiency, rigidity and positional accuracy of mounting points, and optimize NVH performance.

[0042] Optionally, the cross-sectional shape of the first reinforcing protrusion is arc-shaped, and its draft angle and fillet radius are optimized through simulation. The bending angle is greater than 135° and less than 150° to ensure good stamping formability and dimensional stability.

[0043] In this embodiment, a reinforcing plate can also be provided between the first reinforcing protrusion and the second reinforcing protrusion to further improve the strength of the collision energy absorption cavity b. This can strengthen the core force transmission path formed between the roof longitudinal beam and the rear floor longitudinal beam, further improve the overall bending stiffness of the door opening edge, and thus improve the side collision performance of the whole vehicle, thereby reducing the intrusion of the passenger compartment.
