The side reinforcement plate includes a frame structure with an installation port. The upper and lower C-pillar reinforcement plates are connected to the C-pillar and located at the installation port of the rear door frame. There is no connection between the upper and lower C-pillar reinforcement plates, and neither the upper nor lower C-pillar reinforcement plates are connected to the side reinforcement plate. Therefore, the resulting side reinforcement plate assembly is a broken frame structure. This frame structure has poor strength and torsional stiffness. Due to the interruption of the force transmission channel, the force transmission performance is poor, and it is susceptible to top pressure differences, resulting in insufficient durability.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0027] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in the embodiments of this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0028] Based on the background described, as Figure 1 As shown, the side reinforcement plate assembly 01 in the automobile body structure belongs to the inner side panel assembly. The inner side panel assembly is connected with the outer side panel assembly and parts such as A, B, C, and D pillars to form the body side panel assembly. The side reinforcement plate assembly 01 is a key reinforcement component in the body side panel assembly, and its main function is to improve the strength and rigidity of the body side panel.

[0029] The side reinforcement assembly 01 includes a side reinforcement plate 1, an upper C-pillar reinforcement plate 011, and a lower C-pillar reinforcement plate 012. The side reinforcement plate 1 includes a frame structure 11 with mounting openings. The upper C-pillar reinforcement plate 011 and the lower C-pillar reinforcement plate 012 are connected to the C-pillar and located at the mounting openings of the frame structure 11. There is no connection between the upper C-pillar reinforcement plate 011 and the lower C-pillar reinforcement plate 012, and neither the upper C-pillar reinforcement plate 011 nor the lower C-pillar reinforcement plate 012 is connected to the side reinforcement plate 1. Therefore, the frame structure is discontinuous, causing the load transmission path to be interrupted and unable to form a complete force transmission channel, significantly reducing the overall stiffness and strength of the vehicle body. The fractured frame structure 11 cannot effectively disperse and bear external loads, especially under side collisions or top pressure, and is prone to local deformation or failure. The torsional stiffness of the vehicle body will be significantly reduced, affecting the vehicle's handling and comfort. In addition, the interruption of the force transmission channel leads to uneven load distribution and local stress concentration, which can easily cause fatigue cracks or structural failure. During long-term use, due to insufficient structural strength and stress concentration, the side reinforcement plate assembly 01 is prone to fatigue damage, affecting the service life of the vehicle body.

[0030] The following is in conjunction with the appendix Figure 2-6 The embodiments of this application will be described in detail below.

[0031] like Figure 2 and Figure 3 As shown, a side panel reinforcement assembly 01 includes:

[0032] Side reinforcement plate 1, including frame structure 11 with mounting opening;

[0033] The C-pillar reinforcing plate 2 is located at the mounting opening of the frame structure 11. One end of the C-pillar reinforcing plate 2 is connected to one of the mounting opening end faces of the side wall reinforcing plate 1, and the other end of the C-pillar reinforcing plate 2 is connected to the other mounting opening end face of the side wall reinforcing plate 1.

[0034] Specifically, taking the left side panel reinforcement plate 1 of the entire vehicle as an example, the side panel reinforcement plate 1 is located on the left side of the vehicle to improve the strength and rigidity of the left side of the vehicle body. The side panel reinforcement plate 1 includes a frame structure 11 with a mounting port, which is located in the rear frame area of ​​the vehicle body. The side panel reinforcement plate also includes a front door frame structure 12, which is located in the front door frame area of ​​the vehicle body. The mounting port of the frame structure 11 with the mounting port is located on the side of the frame structure 11 away from the front door frame structure 12. This mounting port is used to install the C-pillar reinforcement plate 2. The two ends of the C-pillar reinforcement plate 2 are respectively connected to the two mounting port end faces of the side panel reinforcement plate 1, forming a closed and stable frame structure 11. This ensures that the load can be evenly transmitted through the side panel reinforcement plate 1 and the C-pillar reinforcement plate 2, avoiding stress concentration and reducing local deformation of the side panel reinforcement plate assembly 01, thereby improving the strength, torsional stiffness and durability of the vehicle body.

[0035] Furthermore, the C-pillar supports the roof and forms the frame of the trunk. The C-pillar reinforcement plate 2 and the side reinforcement plate 1 form a closed frame structure. The C-pillar reinforcement plate 2 acts as a connector, effectively transferring the load from the side reinforcement plate 1 to the C-pillar. When the vehicle is subjected to top pressure or side collision, it can effectively disperse the load and reduce the deformation of the vehicle body, thereby improving the structural strength, torsional stiffness and durability of the vehicle body side reinforcement plate assembly 01.

[0036] In some embodiments, such as Figure 2 and Figure 3 As shown, the side reinforcement plate 1 includes a side main frame plate 111, an upper beam reinforcement plate 112, and a sill beam reinforcement plate 113 connected in sequence. The mounting opening is formed between the upper beam reinforcement plate 112 and the sill beam reinforcement plate 113. The two ends of the C-pillar reinforcement plate 2 are respectively connected to the upper beam reinforcement plate 112 and the sill beam reinforcement plate 113, so that the side main frame plate 111, the upper beam reinforcement plate 112, the sill beam reinforcement plate 113, and the C-pillar reinforcement plate 2 form a complete frame structure 11.

[0037] Specifically, the frame structure 11 with the installation port consists of a side main frame plate 111, an upper beam reinforcing plate 112, and a sill beam reinforcing plate 113. The C-pillar reinforcing plate 2 is arranged opposite to the side main frame plate 111. One end of the upper beam reinforcing plate 112 is connected to the side main frame plate 111, and the other end is connected to the C-pillar reinforcing plate 2. One end of the sill beam reinforcing plate 113 is connected to the side main frame plate 111, and the other end is connected to the C-pillar reinforcing plate 2. The upper beam reinforcement plate 112 and the sill beam reinforcement plate 113 are positioned opposite each other. The upper beam reinforcement plate 112 is located at the top of the side wall reinforcement plate 1, which enhances the roof support capacity by strengthening the upper beam. The sill beam reinforcement plate 113 is located at the bottom of the side wall reinforcement plate 1, which enhances the impact resistance of the bottom area of ​​the vehicle body by strengthening the sill beam. The upper beam reinforcement plate 112 and the sill beam reinforcement plate 113 are respectively connected to the side wall main frame plate 111 and the C-pillar reinforcement plate 2, forming two continuous force transmission paths. When the top and bottom of the vehicle body are subjected to impact forces, the load can be effectively transmitted and dispersed, thereby improving the durability and safety of the vehicle body.

[0038] In this embodiment, the upper side beam reinforcement plate 112 enhances the roof support capacity by reinforcing the upper side beam, and the sill beam reinforcement plate 113 enhances the impact resistance of the bottom area of ​​the vehicle body by reinforcing the sill beam. The side main frame plate 111, the upper side beam reinforcement plate 112, the sill beam reinforcement plate 113, and the C-pillar reinforcement plate 2 form a complete and continuous frame structure 11. When the top and bottom of the vehicle body are subjected to impact forces, it ensures that the load can be transferred to the side main frame plate 111 and the C-pillar reinforcement plate 2 through the upper side beam reinforcement plate 112 and the sill beam reinforcement plate 113, thereby effectively transferring and dispersing the load, and thus improving the strength and impact resistance of the vehicle side.

[0039] In some embodiments, such as Figure 2 and Figure 3 As shown, the C-pillar reinforcing plate 2 includes an upper section plate 21, a connecting joint plate 22, and a lower section plate 23 connected in sequence. The upper section plate 21 is connected to the upper side beam reinforcing plate 112, and the lower section plate 23 is connected to the sill beam reinforcing plate 113. In the direction from the upper side beam reinforcing plate 112 to the connecting joint plate 22, the upper section plate 21 gradually moves away from the side main frame plate 111; in the direction from the connecting joint plate 22 to the sill beam reinforcing plate 113, the lower section plate 23 gradually moves closer to the side main frame plate 111.

[0040] In addition, the upper plate 21, the connecting joint plate 22 and the lower plate 23 are integrally formed.

[0041] For example, the C-pillar reinforcement plate 2 is made of 22MnB5+AS40, a high-strength, lightweight, high-performance steel. Its thickness is precisely controlled to 1.0 mm, meeting the stringent structural strength requirements of vehicles while reducing weight to lower overall energy consumption and manufacturing costs, achieving a dual optimization of performance and economy. Furthermore, the yield strength of the 22MnB5+AS40 C-pillar reinforcement plate 2 ranges from 350-550 MPa, significantly improved compared to traditional materials. This allows the C-pillar reinforcement plate 2 to better absorb and disperse impact forces in extreme situations such as collisions, protecting occupants. The C-pillar reinforcement plate 2 is manufactured using a thermoforming process, allowing the upper plate 21, connecting joint plate 22, and lower plate 23 to be integrally formed. This improves the force transmission performance of the C-pillar reinforcement plate 2 and enables the vehicle to better resist various stresses and fatigue damage during long-term use, significantly enhancing the overall vehicle durability.

[0042] In this embodiment, the C-pillar reinforcement plate 2 includes an upper section plate 21, a connecting joint plate 22, and a lower section plate 23 connected in sequence. The upper section plate 21 is used to connect the upper side beam reinforcement plate 112, and the lower section plate 23 is used to connect the sill beam reinforcement plate 113. The connecting joint plate 22 is used to connect the upper section plate 21 and the lower section plate 23, and to connect the lower section plate 23 with the lower section plate 23, so as to effectively transfer the load. In the direction from the connecting joint plate 22 to the sill beam reinforcement plate 113, the upper section plate 21 gradually moves away from the side main frame plate 111, and the lower section plate 23 gradually moves closer to the side main frame plate 111. The resulting C-pillar reinforcement plate 2 is a bent reinforcement plate to adapt to the shape of the C-pillar and the door frame, so that the C-pillar reinforcement plate 2 fits tightly with the C-pillar and the door frame, thereby improving the stability of the vehicle body structure.

[0043] like Figure 2 and Figure 4 As shown, based on the same inventive concept, corresponding to any of the above embodiments, this application also provides a side inner panel assembly 02, including the above-mentioned side reinforcing panel assembly 01;

[0044] The D-pillar reinforcement plate assembly 3 includes a D-pillar reinforcement plate 31 and a CD-pillar connecting plate 32. The D-pillar reinforcement plate 31 is positioned opposite to the upper section plate 21. One end of the D-pillar reinforcement plate 31 is connected to the upper side beam reinforcement plate 112, and the other end is connected to the CD-pillar connecting plate 32. The end of the CD-pillar connecting plate 32 away from the D-pillar reinforcement plate 31 is connected to the connecting joint plate 22. The upper side beam reinforcement plate 112, the D-pillar reinforcement plate 31, the CD-pillar connecting plate 32, the connecting joint plate 22, and the upper section plate 21 form a first window structure.

[0045] Specifically, the upper beam reinforcing plate 112 connects the side wall reinforcing plate assembly 01 and the D-pillar reinforcing plate assembly 3. The upper beam reinforcing plate 112 has three connecting ends for connecting the side wall main frame plate 111, the D-pillar reinforcing plate 31, and the upper section plate 21, respectively. The D-pillar reinforcing plate 31 is a bent reinforcing plate used to enhance the strength of the D-pillar. The CD-pillar connecting plate 32 is used to connect the D-pillar reinforcing plate 31 and the connecting joint plate 22, so that the upper beam reinforcing plate 112, the D-pillar reinforcing plate 31, the CD-pillar connecting plate 32, the connecting joint plate 22, and the upper section plate 21 form a first window structure. This first window structure is a complete and closed rear side window structure, which can significantly improve the overall strength and rigidity of the rear side area of ​​the vehicle body.

[0046] In this embodiment, the D-pillar reinforcing plate 31 is used to enhance the strength of the D-pillar, and the CD-pillar connecting plate 32 is used to connect the D-pillar reinforcing plate 31 and the C-pillar reinforcing plate 22, ensuring that the load is effectively transferred between the D-pillar reinforcing plate 31 and the C-pillar reinforcing plate 2. The upper beam reinforcing plate 112, the D-pillar reinforcing plate 31, the CD-pillar connecting plate 32, the connecting plate 22, and the upper plate 21 form a continuous force transmission path, ensuring that the load can be evenly distributed on the first window structure, avoiding local stress concentration, thereby improving the overall strength and stiffness of the rear side area of ​​the vehicle body.

[0047] In some embodiments, such as Figure 2 , Figure 5 and Figure 6 As shown, the side panel assembly 02 also includes a rear window assembly 4, which is located on one side of the D-pillar reinforcement plate assembly 3. The rear window assembly 4 includes a rear window inner panel 41 and a D-pillar inner panel 42 connected to each other. The D-pillar inner panel 42 is located on the side of the rear window inner panel 41 away from the C-pillar reinforcement plate 2. The upper beam reinforcement plate 112, the upper section plate 21, and the CD-pillar connecting plate 32 are all connected to the rear window inner panel 41. The D-pillar reinforcement plate 31 connects the rear window inner panel 41 and the D-pillar inner panel 42. The rear window inner panel 41 is provided with a second window, and the projection of the second window on the first window structure coincides with the first window on the first window structure.

[0048] Specifically, taking the left side panel assembly as an example, the rear window assembly 4 is located on the side of the D-pillar reinforcement assembly 3 closer to the vehicle interior and is connected to the D-pillar reinforcement assembly 3. The upper beam reinforcement plate 112, the upper section plate 21, and the C-D pillar connecting plate 32 are all connected to the rear window inner panel 41. The D-pillar reinforcement plate 31 connects the rear window inner panel 41 and the D-pillar inner panel 42, so that the load can be transferred from the rear window inner panel 41 to the D-pillar reinforcement assembly 3 and the C-pillar reinforcement plate 2 assembly, increasing the stress transmission path, promoting stress dispersion, and thus enhancing the strength of the rear side of the vehicle body. The second window on the rear window inner panel 41 coincides with the first window on the first window structure in spatial position, forming a complete rear window area, which satisfies both the aesthetics of the vehicle body design and ensures the strength and rigidity of the rear structure of the vehicle body.

[0049] In some embodiments, the side panel assembly 02 further includes a rear wheel arch assembly 5, which is connected to the lower section panel 23 and the CD pillar connecting plate 32.

[0050] Specifically, the rear wheel arch assembly 5 is located below the D-pillar reinforcement plate assembly 3 and behind the side wall reinforcement plate assembly 01. The rear wheel arch assembly 5 includes the rear wheel arch inner plate, the rear wheel arch outer plate, reinforcement components, and mounting structure. It not only protects the wheels and suspension system but also effectively reduces the impact of road noise and vibration on the vehicle body.

[0051] In this embodiment, the stresses on the D-pillar reinforcement plate assembly 3 and the side wall reinforcement plate assembly 01 can be transmitted and dispersed through the rear wheel arch assembly 5, which increases the stress transmission path on the D-pillar reinforcement plate assembly 3 and the side wall reinforcement plate assembly 01, avoids stress concentration, and thus enhances the strength and durability of the overall vehicle body structure.

[0052] In some embodiments, such as Figure 2 , Figure 4 and Figure 6 As shown, the C-pillar reinforcing plate 2 has a first flange edge 6 on the side away from the side main frame plate 111. The first flange edge 6 is connected to the upper side beam reinforcing plate 112, the rear side window inner panel 41, the CD pillar connecting plate 32, the rear wheel arch assembly 5, and the sill beam reinforcing plate 113. The C-pillar reinforcing plate 2 has a second flange edge 7 on the side close to the side main frame plate 111. The two ends of the second flange edge 7 are connected to the upper side beam reinforcing plate 112 and the sill beam reinforcing plate 113, respectively.

[0053] Specifically, the first flange edge 6 and the second flange edge 7 are both integrally formed with the C-pillar reinforcing plate 2. The first flange edge 6 includes an integrally formed upper flange edge 61, a middle flange edge 62 and a lower flange edge 63. The upper flange edge 61, the middle flange edge 62 and the lower flange edge 63 are integrally formed with the C-pillar reinforcing plate 2. The upper flange edge 61 connects the upper section plate 21 and the rear side window inner panel 41. The middle flange edge 62 connects the connecting joint plate 22 and the C-pillar connecting plate 32 and the rear side window inner panel 41. The lower flange edge 63 connects the rear wheel arch assembly 5 and the lower section plate 23 to enhance the stability of the vehicle body side structure.

[0054] In this embodiment, the C-pillar reinforcing plate 2 is tightly connected to the surrounding structure through the first flange edge 6 and the second flange edge 7, forming a continuous reinforcing structure, thereby improving the rigidity and impact resistance of the entire vehicle body side panel.

[0055] In some embodiments, the upper section plate 21 is welded and fixed to the upper side beam reinforcing plate 112, the lower section plate 23 is welded and fixed to the sill beam reinforcing plate 113, the first flange edge 6 is welded and fixed to the upper side beam reinforcing plate 112, the rear side window inner panel 41, the CD pillar connecting plate 32, the rear wheel arch assembly 5 and the sill beam reinforcing plate 113 respectively, and the two ends of the second flange edge 7 are welded and fixed to the upper side beam reinforcing plate 112 and the sill beam reinforcing plate 113 respectively.

[0056] Specifically, the upper section 21 of the C-pillar reinforcement plate 2 is double-welded to the upper side beam reinforcement plate 112, and the lower section 23 of the CD-pillar reinforcement plate 31 is double-welded to the sill beam reinforcement plate 113. The upper flange edge 61 is triple-welded to the upper side beam reinforcement plate 112 and to the rear side window inner panel 41; the middle flange edge 62 is double-welded to the CD-pillar connecting plate 32 and to the rear side window inner panel 41; and the lower flange edge 63 is triple-welded to the outer panel on the rear wheel arch assembly 5 and the sill beam reinforcement plate 113. Both ends of the second flange edge 7 are triple-welded to the upper side beam reinforcement plate 112 and the sill beam reinforcement plate 113, respectively. The double- and triple-welding techniques create reliable welded joints that are less prone to loosening or breakage during long-term use, thus ensuring the stability and durability of the vehicle body side panel inner panel assembly structure. The flange edge 6 is at least 20mm wide to enhance the connection between the C-pillar reinforcement plate and the surrounding structure. This application constructs a side inner panel assembly with three fully closed frame structures by reconstructing the structure of the C-pillar reinforcement plate 2 and changing the welding relationship with the surrounding overlapping parts. This assembly improves the torsional stiffness of the vehicle body, enhances the ability to withstand pressure from the top of the vehicle body, and improves side impact performance and durability.

[0057] Based on the same inventive concept, this disclosure also provides a vehicle including the side inner panel assembly 02 described in any of the above claims. The assembly includes a side reinforcement plate assembly 01 and a D-pillar reinforcement plate assembly 3. The side reinforcement plate assembly 01 consists of a frame structure 11 with mounting openings and a C-pillar reinforcement plate 2. The C-pillar reinforcement plate 2 is located at the mounting openings and connects the two mounting opening end faces of the frame structure to form a closed frame structure. This ensures that the load can be evenly transmitted through the side reinforcement plate 1 and the C-pillar reinforcement plate 2, avoiding stress concentration and reducing local deformation of the side reinforcement plate assembly 01, thereby improving the overall rigidity and durability of the vehicle body.

[0058] The D-pillar reinforcement assembly 3 includes a D-pillar reinforcement plate 31 and a CD-pillar connecting plate 32. One end of the D-pillar reinforcement plate 31 is connected to the upper beam reinforcement plate 112, and the other end is connected to the connecting joint plate 22 of the C-pillar reinforcement plate 2 via the CD-pillar connecting plate 32. The upper beam reinforcement plate 112, the D-pillar reinforcement plate 31, the CD-pillar connecting plate 32, the connecting joint plate 22, and the upper section plate 21 of the C-pillar reinforcement plate 2 together form the first window structure. This closed frame structure ensures the uniform distribution of load in the rear area of ​​the vehicle body, avoids local stress concentration, and further improves the overall strength and rigidity of the vehicle body.

[0059] By redesigning the structure of the C-pillar reinforcement plate 2 and its connection with surrounding components, this application constructs three complete ring-shaped frame structures, significantly improving the vehicle body's torsional stiffness, top pressure resistance, side impact performance, and durability. This design not only optimizes the load transfer path but also enhances the vehicle body's resistance to deformation and safety, making it suitable for various vehicle types, including passenger cars, new energy vehicles, and commercial vehicles, and has broad application prospects.

[0060] It should be noted that the above description describes some embodiments of this application. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recorded in the claims can be performed in a different order than that shown in the above embodiments and still achieve the desired result.
