[0023] In related technologies, the vehicle body side panel mainly includes an outer side panel, a side panel reinforcement plate, and an inner side panel arranged sequentially from the outside to the inside. The outer side panel, the inner side panel, and the side panel reinforcement plate are all welded together from multiple sheet metal parts, which not only have a large weight and volume, but also have a complex assembly process, resulting in low production efficiency and high production cost of the vehicle body side panel.

[0024] To address the problems existing in the aforementioned related technologies, this utility model provides a side panel structure, a vehicle body assembly, and a vehicle.

[0025] Combination Figure 1 and Figure 2 As shown, a side panel structure of this utility model includes a first side panel 1, a side panel 3, and an integrated door ring structure 2. The first side panel 1 is a plastic part and is connected to the outer side of the door ring structure 2. The door ring structure 2 forms a first door opening 24 and a second door opening 25 that are spaced apart along the front and rear direction of the vehicle body, and the inner side of the door ring structure 2 is connected to the side panel 3.

[0026] It should be noted that, Figure 2 The X-axis in the diagram represents the front-to-back direction of the vehicle body, also known as the longitudinal direction, which is also the length direction of the vehicle body. Figure 2 In this context, the Z-axis represents the vertical direction of the vehicle body, also known as the height direction. Figure 3 The Y-axis in the diagram represents the left-right direction of the vehicle body, also known as the left-right direction, which is also the width direction of the vehicle body.

[0027] Specifically, the first side panel 1, the door ring structure 2, and the inner side panel 3 are arranged sequentially along the left-right direction of the vehicle body. The first side panel 1 is a plastic part covering the door ring structure 2. However, the first side panel 1 does not completely cover the door ring structure 2, but rather covers a portion of it, for example... Figure 2 As shown, the first side panel 1 covers the upper half of the A-pillar portion 211, the lower end of the A-pillar portion 211, the lower end of the B-pillar portion 212, and the upper side beam portion 221 of the door ring structure 2 (described later). Both the door ring structure 2 and the inner side panel 3 are in the form of double door rings, that is, the door ring structure 2 and the inner side panel 3 form two door openings for installing the front door and the rear door, respectively. The inner side panel 3 is usually made of multiple sheet metal parts welded together as a whole, while the door ring structure 2 can be formed into an integral double door ring structure by hot stamping, or the door ring body of the door ring structure 2 (i.e., the first plate 21) can be formed into an integral single door ring structure by hot stamping, and then the other components of the door ring structure 2 (i.e., the second plate 22 and the third plate 23) are welded to the door ring body to form an integral double door ring structure. In practical applications, the appropriate production method can be selected as needed, and no specific limitation is made here. During assembly, after the inner side panel 3 is welded together, the door ring structure 2 can be welded to the outer side of the inner side panel 3 as a whole, and then the first side panel trim 1 can be assembled to the outer side of the door ring structure 2.

[0028] In this embodiment, an integrated door ring structure 2 can be connected to the outer side of the inner side panel 3, and a first side panel trim 1, which is made of plastic, can be covered on the outside of the door ring structure 2. This allows for assembly where the door ring structure 2 can be assembled onto the outer side of the inner side panel 3 first, and then the first side panel trim 1 can be assembled onto the outer side of the door ring structure 2 to complete the side panel assembly. This allows the first side panel trim 1 and the door ring structure 2 to replace the traditional sheet metal outer side panel, which not only reduces the weight and material consumption of the side panel structure and lowers production costs, but also simplifies the assembly process, reduces production cycle time, and thus improves production efficiency. Moreover, compared with a single door ring structure, setting the door ring structure 2 as a double door ring structure forming the first door opening 24 and the second door opening 25 can improve the rigidity and stability of the door ring structure 2, resulting in higher structural stability for the vehicle side panel and even the entire vehicle assembly, thus enhancing the overall vehicle safety. In addition, it eliminates the need for the first side panel 1 to undergo electrocoating with the entire vehicle, thus allowing for a variety of colors for the outer side panel by assembling different colors of the first side panel 1.

[0029] Optionally, combined Figure 2 , Figure 5 and Figure 6 As shown, the side panel structure also includes a second side panel 4, and the inner side panel 3 includes a rear wheel cover 31. The door ring structure 2 and the rear wheel cover 31 are respectively connected to the second side panel 4, and the second side panel 4 is a sheet metal part that covers the rear wheel cover 31.

[0030] In this optional embodiment, a second side panel 4 is also provided on the outer side of the door ring structure 2. The rear wheel arch 31 and the second side panel 4 are respectively connected to the inner and outer sides of the C-pillar portion (composed of the C-pillar upper plate portion 222 and the third plate 23) of the door ring structure 2. Moreover, the second side panel 4 is a sheet metal part and covers the rear wheel arch 31. In this way, by providing the second side panel 4 outside the rear wheel arch 31, the rear wheel arch 31 is protected by the second side panel 4. At the same time, by making the second side panel 4 a sheet metal part, components such as rear door latches can be installed and fixed on the second side panel 4 by welding or pre-embedded nuts.

[0031] Optionally, combined Figure 5 , Figure 7 and Figure 8 As shown, the rear wheel arch 31 includes an outer rear wheel arch panel 311 with a clearance hole 3112 for passing the tire. The second side panel 4 has an edging structure 41 that covers the edge of the clearance hole 3112. The rear wheel arch 31 also includes an inner rear wheel arch panel 312 connected to the inner side of the outer rear wheel arch panel 311, forming a downward-facing cavity with the outer rear wheel arch panel 311. The vehicle's rear wheels are mounted in this cavity. This not only improves the stability of the second side panel 4 mounted on the rear wheel arch 31 but also prevents the sharp edges of the outer rear wheel arch panel 311 at the clearance hole 3112 from injuring people.

[0032] Optionally, combined Figure 1 , Figure 5 and Figure 9 As shown, the door ring structure 2 includes a first plate 21, a second plate 22, and a third plate 23. The first plate 21 is an integral door ring that forms the first door opening 24. The second plate 22 and the third plate 23 are respectively connected to the first plate 21 and together with the first plate 21 form the second door opening 25. The side inner panel 3 includes an upper beam inner panel 32 and a C-column inner panel 33 that are connected to each other. The C-column inner panel includes an upper C-column inner panel 331 and a lower C-column inner panel 332. A part of the second plate 22 is opposite to the upper beam inner panel 32, and another part is opposite to the upper C-column inner panel 331. The third plate 23 is opposite to the lower C-column inner panel 332.

[0033] In this optional embodiment, the door ring structure 2 is formed into an integral structure by means of, for example, laser welding, a first plate 21, a second plate 22 and a third plate 23. The first plate 21 is an integral door ring and constitutes the door ring body of the door ring structure 2. In practical applications, the door ring body can be processed by hot stamping, that is, multiple pieces are welded together by laser welding to form a door ring plate, and then the door ring plate is formed into an integral door ring body by hot stamping. The second plate 22 and the third plate 23 together with the B-pillar portion 212 of the first plate 21 form the second door opening 25. Furthermore, a portion of the second plate 22 (i.e., the upper beam portion 221 mentioned later) is positioned opposite to the inner plate 32 of the upper beam, and another portion (i.e., the upper plate portion 222 of the C-pillar mentioned later) is positioned opposite to the upper inner plate 331 of the C-pillar. The third plate 23 is positioned opposite to the lower inner plate 332 of the C-pillar. The third plate 23 is equivalent to the lower plate portion of the C-pillar of the door ring structure 2. In other words, the third plate 23 and the upper plate portion 222 of the C-pillar together constitute the C-pillar portion of the door ring structure 2.

[0034] By dividing the door ring structure 2 into three parts—the first plate 21, the second plate 22, and the third plate 23—segmented manufacturing of the door ring structure 2 is possible. Compared to manufacturing the entire door ring structure 2 using hot stamping, this reduces the manufacturing difficulty of the door ring structure 2 and decreases the size and cost of the stamping dies, thereby lowering the production cost of the door ring structure 2. Furthermore, by positioning a portion of the second plate 22 opposite to the inner plate 32 of the upper side beam, another portion opposite to the inner plate 331 of the C-pillar, and the third plate 23 opposite to the inner plate 332 of the lower C-pillar, the portion of the door ring structure 2 corresponding to the C-pillar is divided into upper and lower parts for segmented manufacturing. This not only further reduces the manufacturing difficulty of the door ring structure 2 but also facilitates adjustments to the structure of the door ring structure 2 at the C-pillar to adapt to different vehicle models, thus improving the versatility of the door ring structure 2.

[0035] Furthermore, combined Figure 9 As shown, the first plate 21 includes an A-pillar portion 211 and a B-pillar portion 212 forming the first doorway 24. The A-pillar portion 211 is approximately a C-shaped structure with its opening facing rearward, and the B-pillar portion 212 is approximately an "I"-shaped structure. The lower ends of the A-pillar portion 211 and the B-pillar portion 212 are respectively positioned opposite to the front and rear halves of the sill inner plate 36 of the side inner plate 3. This achieves the structural design of the first plate 21. Moreover, when welding the sheet metal, the sheet metal forming the A-pillar portion 211 can be welded into the A-pillar plate first, and the sheet metal forming the B-pillar portion 212 can be welded into the B-pillar plate. Then, the A-pillar plate and the B-pillar plate can be welded into the door ring plate. Finally, the first plate 21 is formed by hot stamping, thereby simplifying the production process of the first plate 21 and improving production efficiency.

[0036] Optionally, combined Figure 9 As shown, the second plate 22 includes an upper beam portion 221 and a C-pillar upper plate portion 222. The upper beam portion 221 is disposed opposite to and connected to the upper beam inner plate 32 of the first plate 21. The C-pillar upper plate portion 222 is disposed opposite to the C-pillar upper inner plate 331, with one end connected to the middle position of the upper beam portion 221 and the other end connected to the third plate 23. In this way, the second plate 22 has a roughly Y-shaped structure rotated 90° clockwise, which gives the second plate 22 high rigidity and strength, thereby further improving the stability of the door ring structure 2.

[0037] Optionally, combined Figures 2 to 5 As shown, the side structure also includes a first reinforcing member 5, the first plate 21 includes an A-pillar portion 211, the side inner plate 3 includes an A-pillar inner plate 34, the A-pillar portion 211 and the A-pillar inner plate 34 are arranged opposite to each other and form a first cavity 7, and the first reinforcing member 5 is disposed in the first cavity 7. And / or, the side structure also includes a second reinforcing member 6, the first plate 21 includes a B-pillar portion 212, the inner side panel 3 includes a B-pillar inner panel 35, the B-pillar portion 212 and the B-pillar inner panel 35 are arranged opposite to each other and form a second cavity 8, and the second reinforcing member 6 is disposed in the second cavity 8.

[0038] In this optional embodiment, the first reinforcing member 5 and the second reinforcing member 6 can be sheet metal reinforcing members or plastic reinforcing members. For example, CBS material to be expanded adhesive can be used as the plastic reinforcing member. In this case, the adhesive to be expanded can be fixed in the first cavity 7 and / or the second cavity 8 by means of snap-fit ​​connection, and then the adhesive to be expanded is expanded by baking to play a supporting and connecting role. In this way, by setting a reinforcing member in at least one cavity in the first cavity 7 and the second cavity 8, the rigidity of the side structure and the overall safety of the vehicle can be further improved.

[0039] Optionally, combined Figure 1 , Figure 2 and Figure 5 As shown, the first side panel 1 includes an upper side panel 11 and a sill panel 12 that are detachably connected to the door ring structure 2. The inner side panel 3 includes a rear wheel cover 31 and an inner A-pillar panel 34. The inner A-pillar panel 34 includes an upper inner A-pillar panel 341 and a lower inner A-pillar panel 342 that are connected to each other. The upper side panel 11 covers the upper inner A-pillar panel 341, and one end of the upper side panel 11 extends to the lower inner A-pillar panel 342, while the other end extends to the rear wheel cover 31.

[0040] In this optional embodiment, by setting the first side panel 1 as a split structure including the upper side panel 11 and the sill panel 12, it is easier to manufacture and disassemble the first side panel 1 in sections, reducing production difficulty and improving production efficiency. It also simplifies the structure of the production mold for the first side panel 1, reducing production costs. Furthermore, by using a plastic sill panel 12 instead of the traditional sheet metal sill outer panel (i.e., the sill portion of the sheet metal side panel), when the vehicle is damaged or scratched at the sill panel 12, repairs can be performed by replacing the sill panel 12, without replacing the entire side panel or performing sheet metal repainting, thus significantly saving after-sales maintenance costs. The upper side panel 11 and the sill panel 12 can be detachably connected to the door ring structure 2 using, for example, a snap-fit ​​method for easy disassembly and assembly. Furthermore, the front and rear ends of the side panel 11 extend to the upper end of the lower inner panel 342 of the A-pillar and the upper end of the rear wheel arch 31, respectively, and the front and rear ends of the door sill panel 12 extend to the front end of the lower inner panel 342 of the A-pillar and the front end of the second side panel 4, respectively. This ensures that the side panel 11 and the door sill panel 12 can completely cover the upper and lower edges of the door ring structure 2, thereby better playing a protective and decorative role.

[0041] Optionally, combined Figure 1 , Figure 2 and Figure 5 As shown, the side panel 11 includes an A-pillar upper panel 111 and an upper side beam panel 112, which are sequentially separated along the length of the vehicle body. The A-pillar upper panel 111 is positioned opposite to the A-pillar inner panel 341. One end of the upper side beam panel 112 extends to the rear end of the A-pillar upper panel 111, and the other end of the upper side beam panel 112 extends to the rear wheel arch 31.

[0042] In this way, by designing the side panel 11 as a split structure including the A-pillar upper panel 111 and the upper beam panel 112, it is easier to manufacture the side panel 11 in sections, thereby reducing the manufacturing difficulty of the side panel 11 and improving production efficiency.

[0046] The beneficial effects of the vehicle in this embodiment are the same as those of the vehicle body assembly described above, and will not be repeated here.

[0047] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
