Description

Technical Field

[0001] The present application relates to the field of automotive engineering technology, and in particular to a rear side panel structure, a vehicle body, and a vehicle. Background Art

[0002] With the development of the economy and people's living standards, cars are not only a means of transportation, but also a companion for travel and leisure, and a way to express one's personality. With the growing demand for multi-functional vehicles, the structure of the car is constantly evolving to meet different personalized needs, and cars with partitions are gradually being sought after.

[0003] Because the partition assembly is located in the center of the vehicle, it can be used to separate the passenger area from the luggage area, providing passengers with greater comfort and privacy. When a vehicle with a partition assembly is paired with a sliding rear dome structure, the sliding rear dome can be used to "transform" the vehicle, allowing it to switch between an SUV and a pickup truck.

[0004] However, the partition assembly needs to be connected to the rear side panel structure, and the C-pillar area of the rear side panel structure needs to be connected to the partition assembly by means of overall widening, which will lead to a significant increase in the weight of the rear side panel structure and the entire vehicle, thereby increasing the vehicle's energy consumption. Summary of the Invention

[0005] One of the purposes of this application is to provide a rear side panel structure to solve the problem in the prior art that the partition assembly needs to be connected to the rear side panel structure, which will lead to a significant increase in the weight of the rear side panel structure and the entire vehicle; the second purpose is to provide a vehicle body; and the third purpose is to provide a vehicle.

[0006] In order to achieve the above objectives, the technical solutions adopted in this application are as follows:

[0007] A rear side panel structure, comprising:

[0008] A side panel assembly, the side panel assembly comprising a side panel outer panel assembly;

[0009] A C-pillar assembly is connected to the inner side of the side outer panel assembly. The C-pillar assembly includes a C-pillar inner panel and a C-pillar reinforcement. The C-pillar inner panel includes a C-pillar body. The C-pillar reinforcement is connected to one side of the C-pillar body in the width direction, and the C-pillar reinforcement is used to connect to the partition assembly of the vehicle body.

[0010] According to the above technical means, since the C-pillar reinforcement is connected to one side of the C-pillar body in the width direction, and the C-pillar reinforcement is used to connect with the partition assembly of the vehicle body, the C-pillar body can be widened and connected to the partition assembly through the C-pillar reinforcement. By adding the C-pillar reinforcement, only the weight of one component needs to be increased to reduce the increase in the rear side structure and the weight of the entire vehicle due to the addition of the partition assembly, which is beneficial to controlling the increase in vehicle energy consumption and meets the requirements of energy conservation and emission reduction.

[0011] Furthermore, the C-pillar reinforcement is connected to the side outer panel assembly to form a first closed cavity, and the C-pillar body is connected to the side outer panel assembly to form a second closed cavity. Both the first closed cavity and the second closed cavity are extended along the height direction of the C-pillar assembly.

[0012] According to the above technical approach, since both the first and second enclosed cavities extend along the height of the C-pillar assembly, a dual C-pillar cavity structure is formed, effectively enhancing the structural strength of the C-pillar area and improving the torsional resistance of the rear body. When the rear crossbeam structure is eliminated to accommodate a sliding dome, this dual C-pillar cavity structure can also address the reduced torsional resistance of the rear body caused by the elimination of the rear crossbeam.

[0013] Furthermore, the side panel assembly further includes a side panel rear middle inner panel reinforcement and a CD pillar outer panel middle connecting piece, and the side panel rear middle inner panel reinforcement and the CD pillar outer panel middle connecting piece are both extended along the length direction of the vehicle body;

[0014] The C-pillar inner panel includes a first connecting beam and a second connecting beam, wherein the first connecting beam and the second connecting beam are both connected to the C-pillar body at an angle and are both extended along the length direction of the vehicle body;

[0015] The first connecting beam is connected to the side panel rear middle inner plate reinforcement to form a third closed cavity, and the second connecting beam is connected to the CD pillar outer panel middle connecting member to form a fourth closed cavity.

[0016] According to the above technical means, the first connecting beam is connected to the rear middle inner panel reinforcement of the side panel to form a third closed cavity, and the second connecting beam is connected to the middle connecting member of the CD-pillar outer panel to form a fourth closed cavity, which is used to form two closed cavities extending along the length direction of the vehicle body (i.e., the length direction of the rear side panel structure) at the upper and lower ends of the C-pillar body, which can be used to improve the overall structural strength of the rear side panel structure.

[0017] Furthermore, the side panel assembly further includes a side panel rear lower inner panel reinforcement, wherein the side panel rear lower inner panel reinforcement is connected to the outer side of the C-pillar body and is located inside the second closed cavity;

[0018] The two ends of the side panel rear middle inner panel reinforcement are respectively connected to the side panel rear lower inner panel reinforcement and the D-pillar assembly, and the two ends of the CD-pillar outer panel middle connecting piece are respectively connected to the side panel rear lower inner panel reinforcement and the D-pillar assembly.

[0019] According to the above technical means, the second closed cavity (the area where the main body of the C-pillar is located), the third closed cavity, the fourth closed cavity and the D-pillar assembly can be connected in series to form a closed quadrilateral structure. The quadrilateral structure forms a complete annular load-bearing frame, which can focus on strengthening the structural strength of the connection area between the C-pillar and the D-pillar and the transition area between the third closed cavity and the fourth closed cavity, which can significantly improve the local (i.e., the rear side structure) and overall stiffness of the vehicle body.

[0020] Furthermore, the C-pillar assembly also includes a rear seat belt mounting reinforcement plate, which is arranged between the C-pillar body and the side panel rear lower inner panel reinforcement.

[0021] According to the above technical means, the reinforcement plate installed on the rear seat belt is arranged between the C-pillar body and the side rear lower inner panel reinforcement, and is located inside the second closed cavity. It can not only be used to connect with the rear seat belt, significantly improving the local stiffness of the seat belt installation point; it can also increase the stiffness of the second closed cavity, further improving the torsional resistance of the area where the C-pillar body is located.

[0022] Furthermore, the rear side panel structure also includes a rear wheel hub package assembly, which includes a rear wheel hub package inner plate and an inner plate rear connecting plate. The inner plate rear connecting plate is connected to the inner side of the rear wheel hub package inner plate to form a fifth closed cavity. The inner plate rear connecting plate is extended obliquely upward, and the fifth closed cavity is extended along the length direction of the inner plate rear connecting plate.

[0023] According to the above-mentioned technical means, since the rear connecting plate of the inner panel is extended upward at an angle, the fifth closed cavity is extended along the length direction of the rear connecting plate of the inner panel (that is, extended upward at an angle), which can increase the local stiffness of the rear wheel hub area and reduce deformation caused by torsion or bending. It can also more effectively transfer the load of the rear wheel hub area to other structures of the vehicle body (such as the C-pillar assembly, etc.), reducing local stress concentration.

[0024] Furthermore, the rear wheel hub package assembly also includes an inner panel inner reinforcement plate, which extends along the height direction of the vehicle body and is connected to the C-pillar reinforcement; the inner panel inner reinforcement plate is connected to the inner side of the rear wheel hub package inner panel to form a sixth closed cavity.

[0025] According to the above technical means, the inner reinforcement plate of the inner panel is extended in the height direction to form a support structure perpendicular to the ground, which can significantly improve the longitudinal stiffness of the rear wheel hub pack area. After the inner reinforcement plate of the inner panel is connected to the C-pillar reinforcement, a continuous support structure is formed from the rear wheel hub pack to the C-pillar, which can transfer the force of the rear wheel hub pack assembly to the C-pillar reinforcement, thereby improving the overall torsional stiffness of the rear side panel structure. The inner reinforcement plate of the inner panel is connected to the inner side of the inner panel of the rear wheel hub pack to form a sixth closed cavity, which significantly improves the local bending and torsional stiffness of the rear wheel hub pack assembly, and can improve the overall structural strength of the rear wheel hub inner panel. The sixth closed cavity transfers concentrated loads (such as lateral impacts, etc.) to other vehicle body structures (such as C-pillar reinforcements) through the inner reinforcement plate of the inner panel, which can reduce local stress concentration.

[0026] Furthermore, the top end of the inner panel rear connecting plate is connected to the inner side reinforcing plate of the inner panel, so as to enable the fifth closed cavity and the sixth closed cavity to be arranged at an angle.

[0027] The angled arrangement of the fifth and sixth enclosed cavities creates a "triangular support" structure within the rear hub assembly. This allows for multi-directional load transfer and distribution (e.g., along the length and height of the vehicle), enhancing the overall structural strength of the rear hub assembly. Furthermore, the enclosed structure of the fifth and sixth enclosed cavities blocks the transmission paths of tire cavity noise and road noise, improving the overall NVH performance of the vehicle.

[0028] Furthermore, the rear wheel hub package assembly also includes a rear wheel hub package outer plate and a rear door lock pin reinforcement assembly. The rear door lock pin reinforcement assembly is connected to the outer side of the rear wheel hub package outer plate to form a seventh closed cavity, and the seventh closed cavity extends toward the C-pillar body.

[0029] According to the above technical means, the rear door lock pin reinforcement assembly is connected to the outer side of the rear wheel hub cover outer panel to form a seventh enclosed cavity, which can significantly improve the rigidity of the rear door lock pin installation area. The seventh enclosed cavity is also extended toward the C-pillar body, which can be connected in series with the second enclosed cavity. Part of the force of the rear wheel hub cover assembly is transmitted along the seventh enclosed cavity and the second enclosed cavity, while the other part of the force is transmitted through the fifth enclosed cavity, the sixth enclosed cavity and the first enclosed cavity. This forms two force transmission paths in the height direction of the rear side panel structure, which can achieve load distribution and improve the overall force of the vehicle body.

[0030] Furthermore, the upper end of the rear door lock pin reinforcement assembly is connected to the side panel rear lower inner plate reinforcement of the side panel assembly, and the lower end of the rear door lock pin reinforcement assembly is connected to the lower body assembly of the vehicle body.

[0031] According to the above technical means, not only can the second closed cavity and the lower body assembly be connected in series, but the structural strength of the rear hub package outer panel and the rear hub package assembly can also be improved.

[0032] A vehicle body comprises the above-mentioned rear side panel structure, and further comprises a roof middle cross beam assembly and a lower body assembly, wherein both ends of the roof middle cross beam assembly and the lower body assembly are connected to the rear side panel structure to form a ring structure.

[0033] The aforementioned technical approach allows the left and right rear side panels to be connected in series to form a ring-shaped structure perpendicular to the length of the vehicle body. Because the ring structure offers superior impact resistance, when a vehicle is struck by a side collision, the impact load is dispersed across the vehicle body in multiple directions through the ring structure, avoiding localized stress concentration.

[0034] Furthermore, the C-pillar assembly includes a roof crossbeam connecting plate assembly, the bottom end of the roof crossbeam connecting plate assembly is respectively connected to the C-pillar body and the C-pillar reinforcement, and the top end of the roof crossbeam connecting plate assembly is connected to the end of the top cover crossbeam assembly to form an eighth closed cavity.

[0035] According to the above technical means, the bottom end of the roof crossbeam connecting plate assembly is connected to the C-pillar body and C-pillar reinforcement, respectively, so that the forces acting on the C-pillar body and C-pillar reinforcement can be transmitted to the roof crossbeam connecting plate assembly. The top end of the roof crossbeam connecting plate assembly is connected to the end of the roof center crossbeam assembly to form an eighth closed cavity. This not only improves the structural strength of the connection between the C-pillar assembly and the roof center crossbeam assembly, but also connects the first closed cavity and the second closed cavity through the eighth closed cavity, allowing the forces acting on the rear side panel structure to enter the eighth closed cavity and the roof center crossbeam assembly along two separate paths.

[0036] Furthermore, the vehicle body also includes a partition assembly, which is arranged inside the annular structure.

[0037] According to the above technical means, since the partition assembly is arranged inside the annular structure and the annular structure has strong impact resistance, the partition assembly can be protected by the annular structure to avoid direct impact of local stress concentration on the partition assembly, thereby improving the stability of the partition assembly.

[0038] Furthermore, the partition assembly includes a partition glass run channel assembly and a partition body assembly, the partition body assembly includes a movably arranged partition glass component, and the partition glass component is slidably connected to the partition glass run channel assembly;

[0039] The C-pillar assembly further includes a connecting bracket assembly, which is disposed on the C-pillar reinforcement and is connected to the partition glass run channel assembly.

[0040] According to the above technical means, since the partition glass assembly is slidably connected to the partition glass run channel assembly, the movement of the partition glass assembly can achieve isolation or connection between the space in front of the partition assembly (i.e., the passenger area) and the space behind the partition assembly (i.e., the luggage area), thereby ensuring the independence and privacy of the passenger area. The connecting bracket assembly is installed on the C-pillar reinforcement and connected to the partition glass run channel assembly, which can be used to secure the partition glass run channel assembly to the C-pillar assembly.

[0041] A vehicle comprises the above-mentioned vehicle body.

[0042] The aforementioned technical approach, achieved by adding a single component—the C-pillar reinforcement—to complete the partition assembly, avoids widening the C-pillar structure and significantly increasing vehicle weight. Furthermore, the synergistic effect of multiple enclosed cavities creates two force transmission paths, effectively distributing impact loads from the lower body to the top, thereby reducing deformation under torsional conditions and effectively improving vehicle modal and body stiffness.

[0043] Beneficial effects of this application:

[0044] (1) The present application realizes the installation of the partition assembly in the C-pillar area by adding a C-pillar rear reinforcement. Only the weight of one component needs to be increased to reduce the increase in the rear side panel structure and the weight of the entire vehicle caused by the addition of the partition assembly, which is beneficial to controlling the increase in vehicle energy consumption and meeting the requirements of energy conservation and emission reduction.

[0045] (2) The present application forms two force transmission paths extending in the vertical direction by arranging the C-pillar reinforcement and the C-pillar body side by side, which is conducive to achieving dispersed force transmission and improving the force condition of the vehicle body.

[0069] The following will describe the embodiments of the present application with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand the other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for the purpose of illustrating the present application and are not intended to limit the scope of protection of the present application.

[0070] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. Therefore, the illustrations only show components related to the present application and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0071] See also Figures 1 to 13In a first aspect of an embodiment of the present application, a rear side panel structure is proposed, comprising a side panel assembly 1 and a C-pillar assembly 2. The side panel assembly 1 comprises a side panel outer panel assembly 11, which can be used to form the skeleton basis of the rear side panel structure; the C-pillar assembly 2 is connected to the inner side of the side panel outer panel assembly 11, so that the connection between the C-pillar assembly 2 and the side panel outer panel assembly 11 is tighter, which helps to improve the torsional performance of the vehicle body, such as Figure 1 and Figure 5 shown.

[0072] See also Figure 1 、 Figure 2 and Figure 4 The C-pillar assembly 2 includes a C-pillar inner panel 21 and a C-pillar reinforcement 22. The C-pillar inner panel 21 includes a C-pillar body 211. The C-pillar body 211 extends along the height direction of the vehicle body and can be used to provide side collision protection. The C-pillar reinforcement 22 is connected to one side of the C-pillar body 211 in the width direction and is used to connect to the partition assembly 7 of the vehicle body. The C-pillar reinforcement 22 can widen the C-pillar body 211 and connect to the partition assembly 7. Figure 2 、 Figure 11 and Figure 12 shown.

[0073] It should be noted that, because conventional C-pillars are relatively narrow and typically comprise multiple layers (e.g., 3-4 layers) of sheet metal to ensure strength, simply widening the entire C-pillar would simultaneously increase the width of the three or four layers of sheet metal, significantly increasing the vehicle's weight. However, by adding the C-pillar reinforcement 22, the weight increase associated with the addition of the partition assembly 7 can be reduced by only increasing the weight of one component. This helps control vehicle energy consumption and meets energy conservation and emission reduction requirements.

[0074] In some embodiments of this application, please refer to Figure 1 and Figure 2 Since the partition assembly 7 is usually set at a relatively rearward position, in order to reduce the space occupancy rate of the partition assembly 7 in the passenger area, the C-pillar reinforcement 22 is connected to the rear side of the C-pillar body 211 to prevent the setting of the partition assembly 7 from affecting the rear seat space.

[0075] In some embodiments of this application, please refer to Figure 1 、 Figure 2 and Figure 4 A first connection portion 2111 is provided on the side of the C-pillar body 211 close to the C-pillar reinforcement 22, and a third connection portion 221 is provided on the side of the C-pillar reinforcement 22 close to the C-pillar body 211. The first connection portion 2111 and the third connection portion 221 can be fixedly connected by welding or other means to improve the connection stability and reliability between the C-pillar body 211 and the C-pillar reinforcement 22.

[0076] In some embodiments of this application, please refer to Figure 1 、 Figure 2 and Figure 5 The C-pillar reinforcement 22 connects to the side panel assembly 11 to form a first enclosed cavity 10, while the C-pillar body 211 connects to the side panel assembly 11 to form a second enclosed cavity 20. Both the first enclosed cavity 10 and the second enclosed cavity 20 extend along the height of the C-pillar assembly 2, forming a dual C-pillar cavity structure. This effectively enhances the structural strength of the C-pillar area and improves the torsional resistance of the rear vehicle body. When the rear crossbeam structure is eliminated to accommodate a sliding dome, this dual C-pillar cavity structure can also address the reduced torsional resistance of the rear vehicle body caused by the elimination of the rear crossbeam.

[0077] It should be noted that the C-pillar body 211 and the C-pillar reinforcement 22 are arranged side by side along the length of the vehicle body and connected to the side panel assembly 11 (which can be achieved by welding or riveting, etc.). The first closed cavity 10 and the second closed cavity 20 (i.e., the double C-pillar cavity structure) also extend along the height direction of the vehicle body and are arranged side by side along the length of the vehicle body. The double C-pillar cavity structure is arranged side by side to form a dual-path force transmission channel, so that when the vehicle body is subjected to torsional force, the stress can be more evenly distributed, which can reduce the distortion of the vehicle body. Figure 13 As shown ( Figure 13 The arrows in the figure indicate the force transmission path).

[0078] In some embodiments of this application, please refer to Figure 5 The C-pillar reinforcement 22 has an "X"-shaped cross-section, allowing both sides of the C-pillar reinforcement 22 to connect to the side panel assembly 11 while forming a first enclosed cavity 10 between the C-pillar reinforcement 22 and the side panel assembly 11. Specifically, a fifth connecting portion 223 is provided on the side of the C-pillar reinforcement 22 away from the C-pillar body 211, which can be used to connect to the side panel assembly 11 (e.g., by welding).

[0079] In some embodiments of this application, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6The side panel assembly 1 also includes a side panel rear middle inner panel reinforcement 12 and a CD-pillar outer panel middle connector 13, both of which are extended along the length direction of the vehicle body; the C-pillar inner panel 21 includes a first connecting beam 212 and a second connecting beam 213, both of which are connected to the C-pillar body 211 at an angle and are extended along the length direction of the vehicle body; the first connecting beam 212 is connected to the upper end of the C-pillar body 211, and the second connecting beam 213 is connected to the lower end of the C-pillar body 211; the side panel rear middle inner panel reinforcement 12 is arranged in a corresponding position to the first connecting beam 212, and the CD-pillar outer panel middle connector 13 is arranged in a corresponding position to the second connecting beam 213.

[0080] The first connecting beam 212 is connected to the side panel rear middle inner plate reinforcement 12 to form a third closed cavity 30, and the second connecting beam 213 is connected to the CD-pillar outer panel middle connecting member 13 to form a fourth closed cavity 40, which is used to form two closed cavities extending along the length direction of the vehicle body (i.e., the length direction of the rear side panel structure) at the upper and lower ends of the C-pillar body 211, which can be used to improve the overall structural strength of the rear side panel structure.

[0081] In some embodiments of this application, please refer to Figure 2 and Figure 4 A window frame for installing the rear side window glass assembly 9 is provided in the middle of the C-pillar inner panel 21. The third closed cavity 30 and the fourth closed cavity 40 are formed on the upper and lower sides of the window frame, which can improve the structural strength of the window frame and ensure the installation stability of the rear side window glass assembly 9.

[0082] In some embodiments of this application, please refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The side panel assembly 1 also includes a side panel rear lower inner panel reinforcement 14, which is connected to the outer side of the C-pillar body 211 and is located inside the second closed cavity 20. It can significantly improve the stiffness of the key force-bearing area of the second closed cavity 20, thereby further enhancing the structural strength of the area where the C-pillar body 211 is located.

[0083] The two ends of the side panel rear middle inner panel reinforcement 12 are respectively connected to the side panel rear lower inner panel reinforcement 14 and the D-pillar assembly 3, and the two ends of the CD-pillar outer panel middle connecting member 13 are respectively connected to the side panel rear lower inner panel reinforcement 14 and the D-pillar assembly 3. The second closed cavity 20 (the area where the C-pillar main body 211 is located), the third closed cavity 30, the fourth closed cavity 40 and the D-pillar assembly 3 can be connected in series to form a closed quadrilateral structure. The quadrilateral structure forms a complete annular load-bearing frame, which can focus on strengthening the structural strength of the connection area between the C-pillar and the D-pillar and the transition area between the third closed cavity 30 and the fourth closed cavity 40, and can significantly improve the local (i.e., the rear side panel structure) and overall stiffness of the vehicle body.

[0084] In some embodiments of this application, please refer to Figure 2 、 Figure 4 and Figure 5 The C-pillar assembly 2 also includes a rear seat belt mounting reinforcement plate 23, which is arranged between the C-pillar body 211 and the side rear lower inner panel reinforcement 14, and is located inside the second closed cavity 20. It can not only be used to connect with the rear seat belt, significantly improving the local stiffness of the seat belt mounting point; it can also improve the stiffness of the second closed cavity 20, further improving the torsional resistance of the area where the C-pillar body 211 is located.

[0085] In some embodiments of this application, please refer to Figure 1 、 Figure 7 、 Figure 8 and Figure 9 The rear side structure also includes a rear wheel hub package assembly 4, which includes a rear wheel hub package inner plate 41 and an inner plate rear connecting plate 42. The inner plate rear connecting plate 42 is connected to the inner side of the rear wheel hub package inner plate 41 to form a fifth closed cavity 50. The inner plate rear connecting plate 42 is extended upward at an angle. The fifth closed cavity 50 is extended along the length direction of the inner plate rear connecting plate 42 (that is, extended upward at an angle), which can increase the local stiffness of the rear wheel hub package area, reduce deformation caused by torsion or bending, and can also more effectively transfer the load of the rear wheel hub package area to other structures of the vehicle body (such as the C-pillar assembly 2, etc.), reducing local stress concentration.

[0086] In some embodiments of this application, please refer to Figure 1 、 Figure 7 、 Figure 8 and Figure 9The rear wheel hub assembly 4 also includes an inner panel inner reinforcement plate 43, which extends along the height direction of the vehicle body and is connected to the C-pillar reinforcement 22. The inner panel inner reinforcement plate 43 extends along the height direction to form a support structure perpendicular to the ground, which can significantly improve the longitudinal rigidity of the rear wheel hub area. After the inner panel inner reinforcement plate 43 is connected to the C-pillar reinforcement 22, a continuous support structure is formed from the rear wheel hub to the C-pillar, which can transfer the force of the rear wheel hub assembly 4 to the C-pillar reinforcement 22, thereby improving the overall torsional rigidity of the rear side panel structure. Figure 13 shown.

[0087] The inner panel inner reinforcement plate 43 is connected to the inner side of the rear wheel hub package inner panel 41 to form a sixth closed cavity 60, which significantly improves the local bending and torsional stiffness of the rear wheel hub package assembly 4, and can improve the overall structural strength of the rear wheel hub inner panel. The sixth closed cavity 60 transfers concentrated loads (such as lateral impacts) to other vehicle body structures (such as the C-pillar reinforcement 22) through the inner panel inner reinforcement plate 43, which can reduce local stress concentration.

[0088] In some embodiments of this application, please refer to Figure 1 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 13 A sixth connection portion 224 is provided at the bottom end of the C-pillar reinforcement 22, and a thirteenth connection portion 431 is provided at the top end of the inner panel inner reinforcement plate 43. The sixth connection portion 224 and the thirteenth connection portion 431 can be fixedly connected by welding or the like, thereby realizing the connection between the C-pillar reinforcement 22 and the inner panel inner reinforcement plate 43, and then realizing the series connection of the first closed cavity 10 and the sixth closed cavity 60, so as to facilitate the transmission of force.

[0089] In some embodiments of this application, please refer to Figure 1 、 Figure 7 、 Figure 8 and Figure 13 The top end of the inner panel rear connecting plate 42 is connected to the inner panel inner reinforcement plate 43, allowing the fifth and sixth enclosed cavities 50 and 60 to be arranged at an angle, forming a "triangular support" structure in the area where the rear hub assembly 4 is located. This allows for multi-directional load transfer and distribution (such as along the vehicle's length and height), thereby enhancing the overall structural strength of the rear hub assembly 4. Furthermore, the enclosed structure of the fifth and sixth enclosed cavities 50 and 60 blocks the transmission paths of tire cavity noise and road noise, thereby improving the NVH performance of the entire vehicle.

[0090] In some embodiments of this application, please refer to Figure 1 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 The rear wheel hub assembly 4 also includes a rear wheel hub outer plate 44 and a rear door lock pin reinforcement assembly 45. The rear door lock pin reinforcement assembly 45 is connected to the outer side of the rear wheel hub outer plate 44 to form a seventh closed cavity 70, which can significantly improve the rigidity of the rear door lock pin installation area. The seventh closed cavity 70 is extended toward the C-pillar body 211, and the seventh closed cavity 70 can be connected in series with the second closed cavity 20. This allows part of the force of the rear wheel hub assembly 4 to be transmitted along the seventh closed cavity 70 and the second closed cavity 20, while the other part of the force is transmitted through the fifth closed cavity 50, the sixth closed cavity 60, and the first closed cavity 10. Two force transmission paths are formed in the height direction of the rear side panel structure, which can achieve load distribution and improve the overall force of the vehicle body.

[0091] It should be noted that the rear side panel structure of existing vehicles has only one force transmission path extending in the vertical direction in the C-pillar area. The force transmission path is single and cannot be effectively dispersed, resulting in poor force conditions of the rear side panel structure and difficulty in ensuring its structural stability and reliability.

[0092] In some embodiments of this application, please refer to Figure 1 、 Figure 7 、 Figure 8 and Figure 10 The upper end of the rear door lock pin reinforcement assembly 45 is connected to the side panel rear lower inner panel reinforcement 14 of the side panel assembly 1, and the lower end of the rear door lock pin reinforcement assembly 45 is connected to the lower body assembly 6 of the vehicle body, which not only realizes the series connection between the second closed cavity 20 and the lower body assembly 6, but also improves the structural strength of the rear wheel hub package outer panel 44 and the rear wheel hub package assembly 4.

[0093] In some embodiments of this application, please refer to Figure 1 、 Figure 7 and Figure 8 A ninth connecting portion 411 is provided on the upper edge of the rear hub package inner plate 41, and a sixteenth connecting portion 442 is provided on the inner side of the rear hub package outer plate 44. The ninth connecting portion 411 and the sixteenth connecting portion 442 can be fixedly connected by welding or other means. A tenth connecting portion 412 is provided on the lower edge of the rear hub package inner plate 41 for connection to the lower vehicle body assembly 6.

[0094] In some embodiments of this application, please refer to Figure 1 、 Figure 7 and Figure 8The bottom end of the inner panel rear connecting plate 42 is provided with an eleventh connecting portion 421, which is used to connect with the rear wheel hub package inner plate 41 and the lower body assembly 6 (such as bolt connection, welding and riveting, etc.), and the top end of the inner panel rear connecting plate 42 is provided with a twelfth connecting portion 422, and the top end of the inner panel inner side reinforcement plate 43 is provided with a thirteenth connecting portion 431. The twelfth connecting portion 422 and the thirteenth connecting portion 431 can be fixedly connected by welding or the like, so that the fifth closed cavity 50 and the sixth closed cavity 60 are set at an angle.

[0095] In some embodiments of this application, please refer to Figure 1 、 Figure 7 and Figure 8 The bottom end of the inner side reinforcing plate 43 of the inner panel is provided with a fourteenth connecting portion 432, which can be fixedly connected to the lower body assembly 6 by bolt connection, riveting or welding.

[0096] In some embodiments of this application, please refer to Figure 1 、 Figure 4 、 Figure 7 and Figure 8 A fifteenth connecting portion 441 is provided on the top of the rear hub package outer panel 44, and a second connecting portion 2131 is provided on the bottom of the second connecting beam 213. The fifteenth connecting portion 441 and the second connecting portion 2131 can be fixedly connected by welding or other means, thereby achieving a connection between the C-pillar assembly 2 and the rear hub package assembly 4. A seventeenth connecting portion 443 is provided on one side of the rear hub package outer panel 44 for connection (e.g., welding) to the rear door lock pin reinforcement assembly 45.

[0097] In some embodiments of this application, please refer to Figure 1 、 Figure 7 and Figure 8 The rear wheel hub package assembly 4 also includes a rear wheel hub package reinforcement plate 46, which is used to connect with the C-pillar inner plate 21 and the D-pillar assembly 3 to form a continuous and stable rear side panel structure. The rear wheel hub package reinforcement plate 46 enhances the structural strength of the rear wheel hub package assembly 4 while also achieving force dispersion. When the vehicle collides, the rear wheel hub package reinforcement plate 46 can transfer the collision force from the rear wheel hub package assembly 4 to the C-pillar inner plate 21 and the D-pillar assembly 3, and then disperse it to the entire vehicle body structure to protect the safety of the occupants.

[0098] See also Figures 1 to 13In a second aspect, the present invention provides a vehicle body comprising the rear side panel structure described in the aforementioned embodiment, and further comprising a roof center crossbeam assembly 5 and a lower vehicle body assembly 6. The roof center crossbeam assembly 5 and the lower vehicle body assembly 6 are connected to the rear side panel structure at both ends. The rear side panel structures on the left and right sides of the vehicle body can be connected in series to form a ring-shaped structure perpendicular to the longitudinal direction of the vehicle body. Because the ring structure has good impact resistance, when the vehicle is hit by a side collision, the collision load can be dispersed to multiple directions of the vehicle body through the ring structure, avoiding localized stress concentration.

[0099] In some embodiments of this application, please refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 11 and Figure 13 The C-pillar assembly 2 includes a roof cross-beam connecting plate assembly 24. The bottom end of the roof cross-beam connecting plate assembly 24 is connected to the C-pillar body 211 and the C-pillar reinforcement 22, respectively, so that the forces acting on the C-pillar body 211 and the C-pillar reinforcement 22 can be transmitted to the roof cross-beam connecting plate assembly 24. The top end of the roof cross-beam connecting plate assembly 24 is connected to the end of the roof center cross-beam assembly 5 (which can be achieved by bolting, riveting, or welding), forming an eighth closed cavity 80. This not only improves the structural strength of the connection between the C-pillar assembly 2 and the roof center cross-beam assembly 5, but also connects the first closed cavity 10 and the second closed cavity 20 through the eighth closed cavity 80, allowing the forces acting on the rear side panel structure to enter the eighth closed cavity 80 and the roof center cross-beam assembly 5 along two paths.

[0100] In some embodiments of this application, please refer to Figure 1 、 Figure 2 and Figure 4 The top end of the C-pillar reinforcement 22 is provided with a fourth connecting portion 222, and the bottom end of the roof cross member connecting plate assembly 24 is provided with a seventh connecting portion 241. The seventh connecting portion 241 and the fourth connecting portion 222 are fixedly connected by welding or other means. Specifically, a portion of the seventh connecting portion 241 overlaps the fourth connecting portion 222, and another portion overlaps the top end of the C-pillar body 211, thereby connecting the bottom end of the roof cross member connecting plate assembly 24 to the C-pillar body 211 and the C-pillar reinforcement 22.

[0101] In some embodiments of this application, please refer to Figure 1 and Figure 11 The vehicle body also includes a partition assembly 7, which is arranged inside the annular structure. Since the annular structure has strong impact resistance, the partition assembly 7 can be protected by the annular structure to avoid direct impact of local stress concentration on the partition assembly 7, thereby improving the stability of the partition assembly 7.

[0102] In some embodiments of this application, please refer to Figure 11 and Figure 12 The partition assembly 7 includes a partition glass run channel assembly 71 and a partition body assembly 72. The partition body assembly 72 includes a movably arranged partition glass component 721. The partition glass component 721 is slidably connected to the partition glass run channel assembly 71. The movement of the partition glass component 721 can achieve isolation or connection between the front space of the partition assembly 7 (i.e., the passenger area) and the rear space of the partition assembly 7 (i.e., the luggage area), thereby ensuring the independence and privacy of the passenger area.

[0103] The C-pillar assembly 2 also includes a connecting bracket assembly 25, which is arranged on the C-pillar reinforcement 22, and the connecting bracket assembly 25 is connected to the partition glass run channel assembly 71, which can be used to achieve the fixed setting of the partition glass run channel assembly 71 on the C-pillar assembly 2.

[0104] In some embodiments of the present application, the partition glass run groove assembly 71 is connected to the connecting bracket assembly 25 by bolts. The connecting bracket assembly 25 is provided with strip-shaped mounting holes, which can flexibly adjust the installation position of the partition glass run groove assembly 71 and flexibly adjust the assembly tolerance between the partition glass run groove assembly 71 and the partition main body assembly 72 to ensure that the glass in the partition main body assembly 72 can smoothly enter the glass run groove of the partition glass run groove assembly 71 and achieve sealing when sliding up and down, thereby reducing the noise when the partition glass assembly 721 is raised and lowered, and improving ride comfort.

[0105] In some embodiments of this application, please refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 12 The connecting bracket assembly 25 is an L-shaped structure, and an eighth connecting portion 251 is provided on the side of the connecting bracket assembly 25 facing the C-pillar reinforcement 22, which can be used to connect to the C-pillar reinforcement 22 (such as welding, etc.).

[0106] In some embodiments of this application, please refer to Figure 11 and Figure 12 The vehicle body also includes a rear side window glass assembly 9, which is installed on the outside of the side assembly 1 through sealant and clips, which can prevent the passengers from feeling depressed when there is no rear side window at the rear of the vehicle body.

[0107] In some embodiments of this application, please refer to Figure 11 and Figure 12The vehicle body also includes a vehicle body interior decoration assembly 8, which is used to enhance the comfort and aesthetics of the vehicle body interior. Specifically, the vehicle body interior decoration assembly 8 includes a rear side panel upper trim 81, a C-pillar upper trim 82, a roof lining assembly 83, a rear side panel lower trim 84 and a C-pillar lower trim 85. Among them, the rear side panel upper trim 81 is arranged on the inner side of the rear side window glass assembly 9, and can shield components such as the C-pillar inner panel 21 (such as the first connecting beam 212, the second connecting beam 213, etc.) and the C-pillar reinforcement 22. The C-pillar upper trim 82 is arranged on the outer side of the C-pillar body 211, and can shield the C-pillar body 211. The roof lining assembly 83 is arranged on the outer side of the roof crossbeam connecting plate assembly 24, and can shield the roof crossbeam connecting plate assembly 24. The rear side panel lower trim 84 is disposed on the inner side of the rear hub assembly 4 to shield components such as the rear hub inner panel 41, the inner panel rear connecting plate 42, and the inner panel inner reinforcement plate 43. The C-pillar lower trim 85 is disposed on the inner side of the rear hub assembly 4 to shield components such as the rear hub outer panel 44 and the rear door lock pin reinforcement assembly 45.

[0108] In some embodiments of the present application, the C-pillar upper trim 82 adopts a wave-shaped structural design at the partition glass run channel assembly 71, which can maximize the space of the seating area and enhance riding comfort.

[0109] See also Figures 1 to 13 The third aspect of the embodiments of the present application provides a vehicle, including the body described in the above embodiments, which can avoid a significant increase in the weight of the entire vehicle while realizing the assembly of the partition assembly 7, and through the coordinated action of multiple closed cavities, two force transmission paths can be formed in the C-pillar area, which can effectively disperse the impact load borne by the lower body to the top, thereby reducing the degree of deformation of the entire vehicle under torsional conditions and effectively improving the vehicle modal and body stiffness.

[0110] See also Figure 13 In some embodiments of the present application, the force transmission method in the vehicle body is as follows:

[0111] First, when the lower body assembly 6 is subjected to external force, the force is transmitted to the rear hub assembly 4;

[0112] Then, the rear wheel hub assembly 4 transmits the force upward through the fifth closed cavity 50, the sixth closed cavity 60 and the seventh closed cavity 70, forming three force transmission paths on the rear wheel hub assembly 4;

[0113] The forces transmitted through the fifth and sixth enclosed cavities 50, 60 then converge at the first enclosed cavity 10 and continue to be transmitted upward through the first enclosed cavity 10. The forces transmitted through the seventh enclosed cavity 70 continue to be transmitted upward through the second enclosed cavity 20, forming two longitudinal (i.e., vehicle height) force transmission paths within the C-pillar assembly 2. Simultaneously, the forces transmitted through the second enclosed cavity 20 are also transmitted transversely (i.e., vehicle length) through the third and fourth enclosed cavities 30, 40, forming two transverse force transmission paths within the C-pillar assembly 2 and distributing the forces to the D-pillar assembly 3. This significantly reduces the impact force on the impacted side when the rear side panel is subjected to a side collision, thereby reducing the intrusion of the side collision and effectively protecting the safety of passengers.

[0114] Finally, the upward force transmitted by the first closed cavity 10 and the second closed cavity 20 is transmitted to the eighth closed cavity 80, and is transmitted through the top cover middle cross beam assembly 5 to the annular structure formed by connecting the top cover middle cross beam assembly 5, the lower body assembly 6 and the rear side panel structure.

[0115] By integrating multiple closed cavities, this application achieves a dispersed load transfer within the vehicle body, effectively distributing the impact load borne by the lower body to the top, rear, and other side of the vehicle body, thereby reducing the degree of deformation of the entire vehicle under torsional conditions and effectively improving the vehicle's modal and body stiffness. The annular structure formed by the roof center crossbeam assembly 5, the lower body assembly 6, and the rear side panel structure effectively transfers the impact force of a side collision to the roof center crossbeam assembly 5 and the lower body assembly 6, thereby better protecting the safety of passengers.

[0116] The above embodiments are only preferred embodiments for fully illustrating the present application, and the protection scope of the present application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art based on the present application are within the protection scope of the present application.
