[0058] With the continuous development of the automotive industry, consumers have increasingly higher requirements for the appearance and functionality of automobiles. As a crucial component of a car, the door not only relates to the vehicle's sealing performance but also directly affects its overall aesthetics. In one alternative approach, traditional framed door structures typically include a prominent door frame, which makes it difficult to completely conceal the waterstop strip.

[0059] This application proposes a framed car door 1.

[0060] Please refer to Figures 1 to 7. In one embodiment of this application, the framed door 1 includes an inner panel sub-assembly 10, an outer panel sub-assembly 30, a water-cutting mounting plate 20, and an outer water-cutting assembly 70. The inner panel sub-assembly 10 includes a main body portion 101 and a window frame portion 102, with the window frame portion 102 located above the main body portion 101. The outer panel sub-assembly 30 is disposed corresponding to the main body portion 101 and is connected to the main body portion 101. The water-cutting mounting plate 20 is fixedly mounted on the inner panel sub-assembly 10. It is located between the outer panel sub-assembly 30 and the inner panel sub-assembly 10; the outer water cutter assembly 70 is fixed to the upper end of the water cutter mounting plate 20, the upper end of the outer water cutter assembly 70 is not higher than the upper end of the outer panel sub-assembly 30, and the side of the outer water cutter assembly 70 away from the outer panel sub-assembly 30 is used to abut against the window glass; so as to realize the hidden assembly of the outer water cutter assembly 70, ensuring that the outer water cutter assembly 70 is hidden and invisible on the outside of the framed door 1, and improving the overall aesthetics of the framed door 1.

[0061] In the technical solution of this application, the water-cutting mounting plate 20 is connected to the inner panel sub-assembly 10 to form the inner panel assembly, so that the framed door 1 is divided into three parts: the inner panel assembly, the outer panel sub-assembly 30, and the outer water-cutting assembly 70. The outer panel sub-assembly 30 is provided corresponding to the main body 101 of the inner panel sub-assembly 10, and the water-cutting mounting plate 20 is provided between the outer panel sub-assembly 30 and the inner panel sub-assembly 10. This facilitates the assembly between the inner panel sub-assembly 10 and the water-cutting mounting plate 20, and between the inner panel assembly and the outer panel sub-assembly 30, reduces the impact of the window frame 102 on the overall rigidity of the framed door 1 and the matching accuracy between the assemblies, and also ensures that the outer water-cutting assembly 70 is hidden on the side of the outer panel sub-assembly 30 facing the main body 101, effectively improving the aesthetics of the whole vehicle.

[0062] Specifically, the framed door 1 also includes an outer window frame assembly (not shown), which is located above the outer panel sub-assembly 30, so that the outer window frame assembly and the outer panel sub-assembly 30 constitute the outer panel assembly. Then, the outer panel sub-assembly 30 is assembled with the main body 101, and the outer window frame assembly is assembled with the window frame 102 to form the framed door 1. Since the outer panel sub-assembly 30 and the outer window frame assembly are relatively independent and relatively independent from the inner panel sub-assembly 10, the sealing structure at the upper end of the outer panel sub-assembly 30 (the first edge-wrapping structure 1a below) can be reliably formed, reducing the influence of the outer window frame assembly and the inner panel sub-assembly 10 on the structural forming, thereby improving the rigidity of the outer panel sub-assembly 30 at its upper end, improving the matching accuracy between the outer water-cutting assembly 70 and the outer panel sub-assembly 30, and improving the sealing performance and aesthetics of the framed door 1.

[0063] The water-cutting mounting plate 20 can be connected to the inner panel outer assembly at both ends along the vehicle body direction, leaving an installation space between the middle area of ​​the water-cutting mounting plate 20 and the inner panel outer assembly for the movement of the window glass, and its upper end is used to fix the outer water-cutting assembly 70. By limiting the upper end of the outer water-cutting assembly 70 to not be higher than the upper end of the outer panel sub-assembly 30, the outer water-cutting assembly 70 is hidden on the side of the outer panel sub-assembly 30 facing the main body 101. That is, when looking horizontally at the upper end of the outer panel sub-assembly 30 from outside the framed door, the outer water-cutting assembly 70 cannot be seen, so that the lines of the framed door 1 are smoother, improving the overall appearance quality of the vehicle, and also facilitating the contact between the opposite sides of the outer water-cutting assembly 70 and the outer panel sub-assembly 30 and the window glass respectively to improve the sealing performance of the whole vehicle.

[0064] Please refer to Figures 2 and 3. In the embodiments of this application, the outer panel sub-assembly 30 includes an outer panel body 31 and a waistline reinforcing plate 32. The upper edge of the outer panel body 31 is connected to the waistline reinforcing plate 32 to form a first edge-sealing structure 1a. The remaining edges of the outer panel body 31 are connected to the main body 101 to form a second edge-sealing structure 1b. It is understood that because existing framed doors 1 are limited by the obstruction of the window frame portion 102 of the inner panel sub-assembly 10, edge-sealing equipment 60 such as edge-sealing mold mechanism or roller edge-sealing mechanism cannot perform complete edge-sealing processing on the upper edge of the outer panel sub-assembly 30 from the inside, the sealing performance and rigidity at the upper end of the outer panel sub-assembly 30 cannot be guaranteed, which in turn affects the matching accuracy between the outer panel sub-assembly 30 and the outer water-cutting assembly 70, resulting in the outer water-cutting assembly 70 not being completely hidden. In the embodiments of this application, the outer panel... The upper edge of the body 31 and the waistline reinforcing plate 32 are connected to form the first edge-wrapping structure 1a. This structure can strengthen the rigidity of the waistline of the outer panel body 31, ensuring that the outer water-cutting assembly 70 is reliably hidden below the waistline of the outer panel body 31, thus improving the overall appearance and quality of the vehicle. The first edge-wrapping structure 1a can also improve the overall sealing of the outer panel sub-assembly 30, reducing the possibility of water and other foreign objects entering the outer panel sub-assembly 30 through the connection between the outer panel body 31 and the waistline reinforcing plate 32. Furthermore, since the outer panel sub-assembly 30 is independently set relative to the inner panel sub-assembly 10, before the outer panel sub-assembly 30 is assembled with respect to the inner panel assembly, the edge-wrapping device 60 can flatten the upper edge of the outer panel body 31 from the side of the outer panel sub-assembly 30 facing the inner panel sub-assembly 10, achieving complete edge wrapping and obtaining the outer panel sub-assembly 30, thus improving the processing convenience and reliability of complete edge wrapping.

[0065] When assembling the inner panel sub-assembly 10 and the outer panel sub-assembly 30, the remaining edges of the outer panel body 31 are connected to the edges of the main body 101 to form a second edge-sealing structure 1b, further improving the overall structural rigidity and sealing of the framed door 1, and making the outline of the framed door 1 smoother, thus improving the overall appearance and quality of the vehicle. Furthermore, in one embodiment, at the first edge-sealing structure 1a and the second edge-sealing structure 1b, edge-sealing adhesive 1c is filled between the outer panel body 31 and the waistline reinforcing plate 32, further improving the overall connection reliability and sealing of the outer panel sub-assembly 30.

[0066] The connection methods between the inner panel sub-assembly 10, the outer panel sub-assembly 30, the waistline reinforcing plate 32, and the outer panel body 31 include, but are not limited to, edge binding connection, spot welding, adhesive bonding, and riveting, to ensure that there is a large contact area between the waistline reinforcing plate 32 and the outer panel body 31, and to ensure that the waistline reinforcing plate 32 strengthens the structure of the outer panel body 31. The waistline reinforcing plate 32 is designed with reinforcing plate features, including but not limited to grooves and reinforcing ribs, which help to improve the rigidity of the waistline reinforcing plate 32 itself, and thus help to improve the overall rigidity of the outer panel sub-assembly 30.

[0067] Please refer to Figures 4 and 5. In the embodiments of this application, the upper edge of the outer panel body 31 is provided with a first inward flange 311. The waistline reinforcing plate 32 includes a fitting section 321 that fits the outer panel body 31. The first inward flange 311 covers the upper end of the fitting section 321 to form a first edge-sealing structure 1a. It can be understood that the upper edge of the outer panel body 31 is bent inward to form the first inward flange 311, so as to form a slot for the waistline reinforcing plate 32 to be inserted between the first inward flange 311 and the outer panel body 31. The waistline reinforcing plate 32 is inserted into the slot through the fitting section 321, which can increase the connection area between the waistline reinforcing plate 32 and the outer panel body 31. It also makes it convenient for the first inward flange 311 to overlap the fitting section 321 and be flattened by the edge-sealing device 60 to cover the fitting section 321, forming the first edge-sealing structure 1a, i.e., the AB area shown in Figure 2.

[0068] Furthermore, in the embodiments of this application, the waistline reinforcing plate 32 further includes a connecting section 322, which is bent and connected to the lower end of the fitting section 321. The water-cutting mounting plate 20 includes a first fixing section 22, which is connected to the connecting section 322. In this way, it can play a certain role in positioning the inner panel assembly and the outer panel sub-assembly 30. Combined with the setting of the second edge-wrapping structure 1b, it helps to further improve the connection stability and connection reliability of the framed door 1.

[0069] The first fixing section 22 and the connecting section 322 are fitted together, which facilitates the connection and fixation of the first fixing section 22 and the connecting section 322. The connection methods of the first fixing section 22 and the connecting section 322 include, but are not limited to, screw connection and snap-fit ​​connection. Since the connecting section 322 is bent and connected to the fitting section 321, there is an assembly gap between the connecting section 322 and the outer panel body 31. When the fitting section 321 and the connecting section 322 are connected by the fastening structure, the risk of interference between the fastening structure and the outer panel body 31 can be effectively reduced, and the service life of the outer panel sub-assembly 30 can be extended.

[0070] Specifically, in the embodiments of this application, the connecting segment 322 has a first connecting hole 323, and the first fixing segment 22 has a second connecting hole 221 that mates with the first connecting hole 323. The first connecting hole 323 and the second connecting hole 221 are connected by a fastening structure, which can be configured with bolts 51 or snap fasteners. However, in other embodiments, the connecting segment 322 has a positioning post extending toward the first fixing segment 22. The positioning post has threads or other connecting structures, which can also achieve the connection between the waistline reinforcing plate 32 and the water-cutting mounting plate 20.

[0071] More specifically, in the embodiments of this application, structural adhesive is applied between the first fixing segment 22 and the connecting segment 322; that is, structural adhesive is filled between the two surfaces of the first fixing segment 22 and the connecting segment 322 that are in contact, thereby improving the rigidity of the waistline of the framed door 1.

[0072] Please refer to Figures 6 and 7. In the embodiments of this application, the water-cutting mounting plate 20 further includes a water-cutting mounting section 21 connected to the upper end of the first fixing section 22. An assembly gap is formed between the water-cutting mounting section 21 and the waistline reinforcing plate 32. The outer water-cutting assembly 70 is mounted on the water-cutting mounting section 21. It can be understood that one end of the water-cutting mounting section 21 is connected to the upper end of the first fixing section 22, and the other end extends upward and is disposed away from the waistline reinforcing plate 32, thereby creating a gap between the water-cutting mounting section 21 and the waistline reinforcing plate 32. An assembly gap is formed between the waistline reinforcing plates 32 to facilitate the fixing of the outer water-cutting assembly 70 to the water-cutting mounting section 21. For example, the outer water-cutting assembly 70 is inserted into the water-cutting mounting section 21, with part of it located in the assembly gap and part of it located on the side of the water-cutting mounting section 21 away from the waistline reinforcing plate 32. This facilitates the outer water-cutting assembly 70 to abut against the waistline reinforcing plate 32 and / or the first inner flange 311 on the side away from the inner panel sub-assembly 10, and allows it to deform flexibly when compressed, thereby improving the sealing performance of the framed door 1.

[0073] Since the inner panel assembly includes an inner panel sub-assembly 10 and a water-cutting mounting plate 20, and the inner panel sub-assembly 10 and the water-cutting mounting plate 20 are fixed as a whole, to ensure the connection between the water-cutting mounting plate 20 and the outer panel sub-assembly 30, please refer to Figures 4 and 6. In the embodiments of this application, the inner panel sub-assembly 10 is provided with a mounting passage 103 penetrating the inner panel sub-assembly 10. The mounting passage 103 is provided corresponding to the second connecting hole 221 for the insertion of tools and fastening structures. It can be understood that when assembling the inner panel assembly and the outer panel sub-assembly 30, the mounting passage 103 is correspondingly set with the second connecting hole 221, and the fastening structures and tools are all... The connection can be made through the installation passage 103 and close to the second connecting hole 221. When the connecting section 322 is provided with a first connecting hole 323 that mates with the second connecting hole 221, the fastening structure is configured as a bolt 51. A nut 52 is pre-welded to the side of the connecting section 322 away from the water-cutting mounting plate 20. The bolt 51 is sequentially inserted into the second connecting hole 221 and the first connecting hole 323, and is threadedly connected to the nut 52 under the action of a tool. Alternatively, the fastening structure is configured as a snap fastener. The snap fastener is sequentially inserted into the second connecting hole 221 and the first connecting hole 323, and is engaged with the edge of the first connecting hole 323 by its snap part, with its head pressing against the edge of the connecting hole. In other embodiments, when the connecting section 322 is provided with a positioning post and the positioning post is provided with an external thread, the positioning post is inserted into the second connecting hole 221 and is threadedly connected by a corresponding nut 52, which can realize the connection between the waistline reinforcing plate 32 and the water-cutting mounting plate 20.

[0074] Referring to Figure 6, in an embodiment of this application, the inner panel sub-assembly 10 includes an inner panel body 11 and a window frame reinforcing plate 12. The window frame reinforcing plate 12 is located between the water-cutting mounting plate 20 and the inner panel body 11, which can effectively improve the overall rigidity of the inner panel sub-assembly 10 and the inner panel assembly, and can also facilitate the assembly of the inner water-cutting assembly to a certain extent, thereby improving the sealing performance of the framed door 1. The connection methods between any two or three of the water-cutting mounting plate 20, the inner panel body 11, and the window frame reinforcing plate 12 include, but are not limited to, spot welding, adhesive bonding, and riveting. However, in other embodiments, the inner panel sub-assembly 10 only includes the inner panel body 11.

[0075] Specifically, in the embodiments of this application, the water-cutting mounting plate 20 is spot-welded to the inner panel body 11; and / or the window frame reinforcing plate 12 is spot-welded to the inner panel body 11; that is, the inner panel body 11 is used as the assembly carrier, and the water-cutting mounting plate 20 and / or the window frame reinforcing plate 12 are spot-welded to the inner panel body 11 to form an inner panel assembly. The connection efficiency is high and the connection strength is high, which can effectively ensure the overall strength and rigidity of the inner panel assembly.

[0076] Referring to Figure 6, in this embodiment of the application, the inner panel body 11 has a first through hole 111, and the window frame reinforcing plate 12 has a second through hole 121. The first through hole 111 and the second through hole 121 are correspondingly arranged to form the installation passage 103. The diameters of both the first through hole 111 and the second through hole 121 are larger than the maximum size of the fastening structure, ensuring that the formed installation passage 103 can accommodate the fastening structure and tools, thus improving the assembly convenience of the fastening structure. Furthermore, multiple second connecting holes 221 are provided. In this case, multiple installation passages 103 are correspondingly provided, and they are arranged at intervals along the vehicle body direction together with each second connecting hole 221.

[0077] In the embodiments of this application, the inner panel sub-assembly 10 is further provided with an auxiliary passageway 104 penetrating the inner panel sub-assembly 10. The auxiliary passageway 104 is located below the installation passageway 103 and is used for the operator to remove the fallen fastening structure. It can be understood that the inner panel body 11 is also provided with a first auxiliary hole located below the first through hole 111. When the fastening structure passes through the installation passageway 103 and falls between the inner panel body 11 and the window frame reinforcing plate 12, the operator can use tools to remove the fastening structure from the auxiliary passageway 104 to the first auxiliary hole.

[0078] In the embodiments of this application, the lower edge and side edge of the outer panel body 31 are provided with a second inner flange 312. The second inner flange 312 covers the edge of the inner panel body 11 to form a second edge-wrapping structure 1b. It can be understood that the upper edge and side edge of the outer panel body 31 are bent inward to form the second inner flange 312, so as to form a slot for the inner panel body 11 to be inserted between the second inner flange 312 and the outer panel body 31. The inner panel body 11 is inserted into the slot, and the second inner flange 312 is flattened under the pressure of the edge-wrapping device 60 to cover the inner panel body 11, forming the second edge-wrapping structure 1b, that is, the BCDA area shown in FIG3, and the second edge-wrapping structure 1b is U-shaped.

[0079] Referring to Figure 4, in an embodiment of this application, the water-cutting mounting plate 20 further includes a second fixing section 24 connected to the lower end of the first fixing section 22. The second fixing section 24 is connected to the outer panel body 31, so that the water-cutting mounting plate 20, the waistline reinforcing plate 32, and the outer panel body 31 enclose a reinforcing cavity. This arrangement, on the one hand, helps to enhance the connection stability and rigidity of the water-cutting mounting plate 20, thereby improving the connection stability and overall rigidity of the outer panel sub-assembly 30 and the inner panel assembly. On the other hand, it can, to a certain extent, give the framed door 1 vibration damping and buffering performance, improving the safety of the vehicle during driving. However, in other embodiments, the waistline reinforcing plate 32 encloses the outer panel body 31 or the water-cutting mounting plate 20 to form a reinforcing cavity.

[0080] Referring to Figure 4, in this embodiment of the application, a transition section 23 connects the first fixing section 22 and the second fixing section 24. The transition section 23 is inclined, and the second fixing section 24 is positioned close to the outer panel body 31. This design utilizes the inclined arrangement of the transition section 23 and the bending connection between the connecting section 322 and the fitting section 321 to increase the reinforcing cavity and enhance vibration damping performance. Furthermore, the proximity of the second fixing section 24 to the outer panel body 31 improves the ease of connection between the second fixing section 24 and the outer panel body 31. One end of the transition section 23 connects to the lower end of the first fixing section 22, while the other end extends towards the second fixing section 24, gradually approaching the outer panel body 31, ensuring that the second fixing section 24 can be as close as possible to or fit against the outer panel body 31. The water-cutting installation section 21, the first fixing section 22, the transition section 23, and the second fixing section 24 can be integrally formed.

[0081] Referring to Figures 4 and 6, in the embodiments of this application, an expanding adhesive 242 is provided between the second fixing segment 24 and the outer panel body 31. It can be understood that the expanding adhesive 242 is applied to the surface of the water-cutting mounting plate 20 facing the outer panel body 31. After the expanding adhesive 242 expands due to heat, the second fixing segment 24 and the outer panel body 31 are tightly bonded together. Thus, it plays a role in vibration reduction during high-speed vehicle operation, a buffering role when the vehicle collides, and can also reduce the noise generated by vibration.

[0082] Specifically, in the embodiments of this application, the surface of the second fixing segment 24 facing the outer panel body 31 is provided with a filling groove 241, which is used to fill the expanding adhesive 242. This can effectively increase the contact area between the expanding adhesive 242 and the second fixing segment 24, thereby improving the connection strength between the expanding adhesive 242 and the second fixing segment 24. However, in other embodiments, the surface of the second fixing segment 24 facing the outer panel body 31 is provided with ribs, and the expanding adhesive 242 is applied to the area where the ribs are located, which can also improve the connection strength between the expanding adhesive 242 and the second fixing segment 24.

[0083] This application also proposes a vehicle including a framed door 1. The specific structure of the framed door 1 is as described in the above embodiments. Since this vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0084] This application also proposes a method for processing a framed car door 1. The specific structure of the framed car door 1 is as described in the above embodiment. The method for processing the framed car door 1 includes the following steps:

[0085] The outer panel sub-assembly 30 is pressed once by the edge-sealing equipment 60, so that the upper edge of the outer panel sub-assembly 30 has a first edge-sealing structure 1a.

[0086] The outer panel sub-assembly 30 is placed corresponding to the main body 101 of the inner panel sub-assembly 10, and the outer panel sub-assembly 30 and the main body 101 are edged a second time by the edge-wrapping device 60 to form a second edge-wrapping structure 1b provided along the lower edge and side edge of the main body 101.

[0087] Understandably, the framed door 1 is edged in two stages to reduce the impact of the window frame portion 102 of the inner panel sub-assembly 10 on the assembly of the framed door 1. In this stage, the edge-sealing device 60 presses the outer panel sub-assembly 30 once. At this time, the edge-sealing device 60 can move from the side of the outer panel sub-assembly 30 facing the inner panel sub-assembly 10 toward the outer panel sub-assembly 30 and flatten the structure at the upper edge of the outer panel sub-assembly 30, achieving complete edge sealing of the AB area as shown in Figure 2, thus forming the first edge-sealing structure 1a. This improves the rigidity at the waistline of the outer panel sub-assembly 30, thereby improving the matching accuracy between the outer water-cutting assembly 70 and the outer panel sub-assembly 30, and ensuring that the outer water-cutting assembly 70 can be reliably hidden inside the outer panel sub-assembly 30, thereby improving the overall appearance quality of the vehicle.

[0088] The outer panel sub-assembly 30 and the main body 101 are edged a second time using the edge-wrapping device 60. At this time, the outer panel sub-assembly 30 is positioned corresponding to the main body 101 of the inner panel sub-assembly 10, ensuring that the lower edge and side edge of the outer panel sub-assembly 30 correspond one-to-one with the lower edge and side edge of the main body 101. The edge-wrapping device 60 moves from the side of the inner panel sub-assembly 10 away from the outer panel sub-assembly 30 towards the corresponding edge, flattening the structure at the lower edge and side edge of the outer panel sub-assembly 30. This achieves edge wrapping in the BCDA area as shown in Figure 3, forming the second edge-wrapping structure 1b. This improves the overall structural rigidity and sealing of the framed door 1, and makes the contour lines of the framed door 1 smoother, thus enhancing the overall appearance and quality of the vehicle. The edge-wrapping device 60 includes, but is not limited to, an edge-wrapping mold mechanism and a rolling mechanism.

[0089] Please refer to Figures 2 and 5. In the embodiments of this application, the step of pressing the outer panel sub-assembly 30 once by the edge-sealing device 60 to give the upper edge of the outer panel sub-assembly 30 a first edge-sealing structure 1a includes:

[0090] The upper edge of the outer panel body 31 of the outer panel sub-assembly 30 is bent inward to form the first inner flange 311.

[0091] The upper edge of the waistline reinforcing plate 32 of the outer panel sub-assembly 30 is placed between the outer panel body 31 and the first inner flange 311;

[0092] The first inner flange 311 is pressed onto the waistline reinforcing plate 32 by the edge-sealing device 60 to cover the waistline reinforcing plate 32 and form the first edge-sealing structure 1a.

[0093] Specifically, the outer panel sub-assembly 30 includes an outer panel body 31 and a waistline reinforcing plate 32. The upper edge of the outer panel body 31 is bent inward toward the inner panel sub-assembly 10 to form a first inner flange 311. A first slot is formed between the first inner flange 311 and the outer panel body 31 to provide pre-edge wrapping for the forming of the first edge wrapping structure 1a, facilitating the pre-assembly of the waistline reinforcing plate 32. The upper edge of the waistline reinforcing plate 32 is inserted into the first slot, and the movement of the waistline reinforcing plate 32 toward the inner panel sub-assembly 10 is restricted by the first inner flange 311, achieving pre-assembly. The edge wrapping device 60 moves from the side of the outer panel sub-assembly 30 facing the inner panel sub-assembly 10 toward the first flange and flattens the first flange toward the waistline reinforcing plate 32, achieving complete edge wrapping of the AB area as shown in Figure 2, thus forming the first edge wrapping structure 1a.

[0094] Referring to Figure 3, in an embodiment of this application, the step of placing the outer panel assembly 30 corresponding to the main body 101 of the inner panel assembly 10, and then using the edge-sealing device 60 to perform secondary edge-sealing on the outer panel assembly 30 and the main body 101 to form a second edge-sealing structure 1b along the lower edge and side edge of the main body 101 includes:

[0095] The lower edge and side edge of the outer panel body 31 of the outer panel sub-assembly 30 are bent inward to form a second inner flange 312.

[0096] The lower edge and side edge of the inner panel body 11 of the inner panel sub-assembly 10 are inserted between the outer panel body 31 and the second inner flange 312 respectively.

[0097] The second inner flange 312 is pressed onto the inner panel body 11 by the edge-sealing device 60 to cover the inner panel body 11 and form the second edge-sealing structure 1b.

[0098] Specifically, the inner panel sub-assembly 10 includes an inner panel body 11. The lower edge and side edge of the outer panel body 31 are bent inward toward the vehicle, that is, bent toward the inner panel sub-assembly 10 to form a second inner flange 312. A second slot is formed between the second inner flange 312 and the outer panel body 31 to provide pre-edge wrapping for the forming of the second edge wrapping structure 1b, which facilitates the pre-assembly of the inner panel body 11. The lower edge and side edge of the inner panel body 11 are inserted into the second slot, and the movement of the inner panel body 11 away from the outer panel sub-assembly 30 can be restricted by the second inner flange 312 to achieve pre-assembly. The edge wrapping device 60 moves from the side of the inner panel sub-assembly 10 away from the outer panel sub-assembly 30 toward the second flange and flattens the second flange toward the inner panel body 11 to achieve edge wrapping of the BCDA area as shown in Figure 3, thus forming the second edge wrapping structure 1b.
