[0030] 10-Body structure. Detailed Implementation

[0031] Exemplary embodiments of the present application will now be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited to the embodiments set forth herein.

[0032] The vehicle body structure typically includes a front structure, a rear structure, and a floor structure. The front structure can be, for example, a front engine compartment structure, and the rear structure can be a rear engine compartment structure. The floor structure includes a front floor structure and a rear floor structure, with the front floor structure connected to the front structure and the rear floor structure connected to the rear structure.

[0033] In the design and production process of the vehicle body structure, the front structure, rear structure and floor structure are usually manufactured by molding them as a single piece. That is, the front structure, rear structure and floor structure are independent structures. After these three parts are formed, they can be connected by welding and other processes to form the vehicle body structure.

[0034] In related technologies, to ensure the structural strength and rigidity of the front and rear structures, the front and rear structures are typically made of steel, while the floor structure is usually formed using an aluminum extrusion process. Therefore, due to the differences in materials, the connection between the floor structure and the rear structure, or between the floor structure and the front structure, can usually only be achieved using screws.

[0035] Specifically, taking the connection between the floor structure and the rear structure as an example, as mentioned above, the rear structure is actually connected to the rear floor structure in the floor structure. More specifically, the rear structure can usually include the rear columns and the rear skirt. The connection between the floor structure and the rear structure is mainly reflected in the connection between the rear floor structure and the rear skirt, that is, the rear floor structure is screwed to the rear skirt.

[0036] The screws are bolted between the rear floor structure and the rear skirt. The screws are easily affected by vehicle vibration and may shift or loosen, resulting in insufficient connection strength. In addition, the force transmission channel is formed between the floor structure and the rear skirt. Compared with the overall rear structure, the coverage of the force transmission channel is insufficient, which affects the overall rigidity and strength of the vehicle body structure.

[0037] Based on the above-mentioned situation and problems, this application provides a floor structure that has been optimized and upgraded to allow it to connect to various components in the rear structure. For example, the floor structure can be connected to the rear skirt and the rear pillar, thereby expanding the coverage of the force transmission channel while improving the connection strength between the floor structure and the rear structure, resulting in better force transmission between the floor structure and the rear structure, and thus improving the rigidity and strength of the vehicle body structure.

[0038] To achieve the above objectives, the floor structure in this embodiment of the application adds a connecting panel while maintaining its inherent structure. The connecting panel is designed in two aspects: one is to make its shape adaptable to the rear structure, and the other is to make its material adaptable to the rear structure. The connecting panel is located at one end of the floor structure near the rear structure, so that the connecting panel can be connected to the rear structure by both screwing and welding, thereby improving the connection strength and enhancing the rigidity and strength of the vehicle body structure.

[0039] Based on the above-mentioned floor structure, this application embodiment also provides a vehicle body structure, which includes at least a floor structure and a rear structure. The floor structure can be connected to various components in the rear structure, thereby expanding the coverage of the force transmission channel while improving the connection strength between the rear floor and the rear structure, resulting in better force transmission between the rear floor and the rear structure, thereby improving the rigidity and strength of the vehicle body structure.

[0040] Based on the aforementioned floor structure or vehicle body structure, this application embodiment also provides a vehicle with excellent rigidity and strength.

[0041] Figure 1 A schematic diagram of a vehicle body structure 10 provided according to an embodiment of this application is shown.

[0042] In the embodiments of this application, please refer to Figure 1 The vehicle body structure 10 includes a rear structure 100 and a floor structure 200.

[0043] The rear structure 100 may be a part used to form the rear engine compartment; otherwise, the rear structure 100 may be other structures or include other structures. The main function of the rear structure 100 is to ensure the rigidity and strength of the rear of the vehicle body structure 10.

[0044] Please refer to Figure 1 The rear structure 100 in this embodiment includes a rear pillar 110 and a rear skirt 120. There are usually two rear pillars 110, which are spaced apart along the width direction of the vehicle. The rear skirt 120 is connected between the two rear pillars 110.

[0045] It is understandable that, due to differences in structural design, different body structures 10 can adopt different rear structures 100. For a body structure 10 including a rear pillar 110 and a rear skirt 120, the specific structures of the rear pillar 110 and the rear skirt 120 can be varied. For example, in Figure 1 In the example shown, the rear pillar 110 is tilted at a certain angle, and the rear skirt 120 and the two rear pillars 110 roughly form a U-shaped structure.

[0046] The floor structure 200 includes a connecting panel 210, which includes a first panel 211 corresponding to the rear upright 110, a second panel 212 corresponding to the rear skirt 120, and a third panel 213 connecting the first panel 211 and the second panel 212. The first panel 211 in the floor structure 200 is connected to the rear upright 110 by screwing and / or welding, the second panel 212 in the floor structure 200 is connected to the rear skirt 120 by screwing and / or welding, and the third panel 213 is connected to the rear upright 110 and the rear skirt 120 by screwing and / or welding.

[0047] The connecting panel 210 is a new structure in the floor structure 200. The connecting panel 210 serves to connect the floor structure 200 and the rear structure 100. Specifically, the first panel 211 is connected to the rear column 110, the second panel 212 is connected to the rear skirt 120, and the third panel 213 is connected to both the rear column 110 and the rear skirt 120. The third panel 213 also strengthens the overall structural strength of the connecting panel 210. Furthermore, as can be seen from the following embodiments, the connecting panel 210 is located at one end of the floor structure 200 and can make full use of the end space of the floor structure 200. Based on the connection between the first panel 211 and the rear pillar 110, the connection between the second panel 212 and the rear skirt 120, and the connection between the third panel 213 and the rear pillar 110 and the rear skirt 120, a larger connection area or more connection points can be formed between the floor structure 200 and the rear structure 100. This can expand the coverage of the force transmission channel while improving the connection strength between the floor structure 200 and the rear structure 100, making the force transmission effect between the floor structure 200 and the rear structure 100 better, thereby improving the rigidity and strength of the vehicle body structure 10.

[0048] Furthermore, it is understood that, compared to the traditional single connection method of screwing between the floor structure 200 and the rear structure 100, in the embodiments of this application, at least one connection method of screwing and welding can be used between the first enclosure 211 and the rear pillar 110, between the second enclosure 212 and the rear skirt 120, and between the third enclosure 213 and the rear pillar 110 and the rear skirt 120. For example, screwing and welding can be used simultaneously, thereby enhancing the force transmission channel and making the force transmission between the floor structure 200 and the rear structure 100 smoother, thereby further improving the rigidity and strength of the vehicle body structure 10.

[0049] In this embodiment, based on the arrangement of the connecting panels 210 in the floor structure 200, specifically, based on the adoption of at least one connection method among bolted and welded between the first panel 211 and the rear column 110, the adoption of at least one connection method among bolted and welded between the second panel 212 and the rear skirt 120, and the adoption of at least one connection method among bolted and welded between the third panel 213 and the rear column 110 and the rear skirt 120, on the one hand, it can effectively prevent adverse consequences such as failure of a single connection method, thereby achieving the purpose of improving the connection strength between the rear structure 100 and the floor structure 200. On the other hand, it can also enable the floor structure 200 and the rear structure 100 to form a larger connection area or more connection points, thereby achieving the purpose of expanding the coverage of the force transmission channel. In summary, based on the setting of the connecting panel 210, the embodiments of this application can achieve the purpose of expanding the coverage of the force transmission channel while improving the connection strength between the floor structure 200 and the rear structure 100, so that the force transmission effect between the floor structure 200 and the rear structure 100 is better, thereby improving the rigidity and strength of the vehicle body structure 10.

[0050] Figure 2 A schematic diagram of a floor structure 200 provided according to an embodiment of this application is shown.

[0051] In the embodiments of this application, please refer to Figure 1 and Figure 2 The floor structure 200 includes a floor body 220 and a connecting panel 210.

[0052] The floor body 220 can adopt the traditional structural form of the floor structure 200. For example, the floor body 220 can be formed into a cavity structure by aluminum extrusion process, and the floor body 220 can be constructed as an aluminum extrusion beam structure.

[0053] It is understood that the floor body 220 is an inherent component of the floor structure 200, and the connecting panel 210 is a new structure in the floor structure 200, and the connecting panel 210 can be connected to the floor body 220.

[0054] The connecting panel 210 is located at one end of the floor body 220 near the rear structure 100. The connecting panel 210 includes a first panel 211 corresponding to the rear upright 110, a second panel 212 corresponding to the rear skirt 120, and a third panel 213 connecting the first panel 211 and the second panel 212. The first panel 211 is connected to the rear upright 110 by screwing and / or welding, the second panel 212 is connected to the rear skirt 120 by screwing and / or welding, and the third panel 213 is connected to the rear upright 110 and the rear skirt 120 by screwing and / or welding.

[0055] As mentioned above, when welding is used, the corresponding part of the connecting panel 210 needs to be made of the same material as the floor body 220. For example, when the first panel 211 and the rear column 110 are welded together, the first panel 211 can be made of steel. In this case, for the floor structure 200 as a whole, the floor structure 200 is an aluminum-steel hybrid structure, which can meet the development needs of the hybrid structure of the floor structure 200.

[0056] In this embodiment, based on the arrangement of the connecting panels 210 in the floor structure 200, specifically, based on the adoption of at least one connection method among bolted and welded between the first panel 211 and the rear column 110, the adoption of at least one connection method among bolted and welded between the second panel 212 and the rear skirt 120, and the adoption of at least one connection method among bolted and welded between the third panel 213 and the rear column 110 and the rear skirt 120, on the one hand, it can effectively prevent adverse consequences such as failure of a single connection method, thereby achieving the purpose of improving the connection strength between the rear structure 100 and the floor structure 200. On the other hand, it can also enable the floor structure 200 and the rear structure 100 to form a larger connection area or more connection points, thereby achieving the purpose of expanding the coverage of the force transmission channel. In summary, based on the setting of the connecting panel 210, the embodiments of this application can achieve the purpose of expanding the coverage of the force transmission channel while improving the connection strength between the floor structure 200 and the rear structure 100, so that the force transmission effect between the floor structure 200 and the rear structure 100 is better, thereby improving the rigidity and strength of the vehicle body structure 10.

[0057] In some embodiments, please refer to Figure 1 and Figure 2 The floor body 220 includes a top wall 221, and a first surrounding plate 211 extends from the top wall 221 toward the top of the floor body 220. The first surrounding plate 211 is provided with a first screw position 2111 and / or a first welding position 2112.

[0058] by Figure 2Taking the coordinate system in the example, the Z direction indicates upwards, so it can be understood that the first enclosure 211 can extend from the top wall 221 along the Z direction.

[0059] It is important to understand that, in the above description, "extending upwards" only indicates the overall structural trend of the first enclosure 211, and does not mean that the first enclosure 211 is a flat plate. In other words, any upward extension of the entire or part of the structure of the first enclosure 211 falls within the scope represented by the above wording.

[0060] The first screw-in position 2111 on the first enclosure 211 is used to meet the screw-in requirements between the first enclosure 211 and the rear column 110, for example, the first enclosure 211 can be connected to the rear column 110 by screws or bolts. The first welding position 2112 on the first enclosure 211 is used to meet the welding requirements between the first enclosure 211 and the rear column 110, for example, the first enclosure 211 can be connected to the rear column 110 by laser welding.

[0061] In conjunction with the foregoing, the specific structure of the first enclosure 211 can be varied according to the specific structure of the rear column 110, with the aim of making the first enclosure 211 fit against the surface of the rear column 110, thereby making the connection strength between the first enclosure 211 and the rear column 110 higher.

[0062] In some embodiments, please refer to Figure 2 The first panel 211 includes a first end 2113 and a second end 2114. The first end 2113 is close to the rear skirt 120, and the second end 2114 is far away from the rear skirt 120. The height of the first panel 211 gradually decreases from the first end 2113 to the second end 2114.

[0063] You can refer to the following: Figure 1 The height difference between the first end 2113 and the second end 2114 can be adapted to the overall shape of the rear column 110. Figure 1 In the example shown, the structural thickness of the rear column 110 corresponding to the first end 2113 is less than the structural thickness of the rear column 110 corresponding to the second end 2114. By setting the height of the first end 2113 to be higher than that of the second end 2114, the structural difference can be effectively balanced, thereby improving the connection strength between the first enclosure 211 and the rear column 110, and also helping to optimize the force transmission channel.

[0064] Of course, when the rear column 110 adopts other structural forms, the height relationship between the first end 2113 and the second end 2114 can be changed. For example, the first end 2113 and the second end 2114 can be flush, or the height of the first end 2113 can be less than the height of the second end 2114.

[0065] In the above description, height can be understood with reference to the Z direction, and the height difference indicates that the dimensions of the corresponding structure differ along the Z direction.

[0066] In some embodiments, please refer to Figure 1 and Figure 2 The first screw connection 2111 includes a first screw hole and a second screw hole, which are located at different heights.

[0067] The first screw hole and the second screw hole allow the first enclosure 211 to be connected to the rear column 110 by screwing.

[0068] It should be noted that the first screw position 2111 may also include more screw holes, which will not be described in detail here.

[0069] It is understandable that the height difference between the first screw hole and the second screw hole can be understood by referring to the height difference between the first end 2113 and the second end 2114 mentioned above. Its overall purpose is to adapt to the overall shape of the rear column 110.

[0070] In some embodiments, the first soldering position 2112 includes a first solder pad located below the first screw position 2111, or the first screw position 2111 is located within the first solder pad.

[0071] By setting the first welding pad, the first enclosure 211 can be connected to the rear column 110 by welding.

[0072] When the first pad is below the first screw position 2111, two types of connection positions can be formed in the height direction, with the screw position on top and the solder position on the bottom. When the first pad is inside the first screw position 2111, the two types of connection positions can closely interact.

[0073] Of course, in other embodiments, the positional relationship between the first pad and the first screw position 2111 can be varied further, and this application does not limit this.

[0074] In some embodiments, please refer to Figure 1 and Figure 2 The floor body 220 may also include a side wall 222, and a second enclosure 212 extends from the side wall 222 toward the side of the floor body 220. The second enclosure 212 is provided with a second screw position and / or a second welding position 2121.

[0075] by Figure 2 Taking the coordinate system in the example, the direction opposite to the X direction indicates the side, so it can be understood that the second enclosure 212 can extend from the side wall 222 in the direction opposite to the X direction.

[0076] It is important to understand that, in the above description, "extending laterally" only indicates the overall structural trend of the second enclosure 212, and does not mean that the second enclosure 212 is a flat plate. In other words, the lateral extension of all or part of the structure of the second enclosure 212 falls within the scope represented by the above wording.

[0077] The second screw-in position on the second enclosure 212 is used to meet the screw-in requirements between the second enclosure 212 and the rear skirt 120. For example, the second enclosure 212 can be connected to the rear skirt 120 by screws or bolts. The second welding position 2121 on the second enclosure 212 is used to meet the welding requirements between the second enclosure 212 and the rear skirt 120. For example, the second enclosure 212 can be connected to the rear skirt 120 by laser welding.

[0078] In conjunction with the foregoing, the specific structure of the second panel 212 can be varied according to the specific structure of the rear skirt 120, with the aim of making the second panel 212 fit against the surface of the rear skirt 120, thereby making the connection strength between the second panel 212 and the rear skirt 120 higher.

[0079] In some embodiments, please refer to Figure 1 and Figure 2 The second screw connection includes multiple third screw holes (not shown in the figure), which are arranged along the height direction.

[0080] The third screw hole allows the second enclosure 212 to be screwed onto the rear skirt 120.

[0081] In some embodiments, please refer to Figure 1 and Figure 2 The second soldering position 2121 includes a second solder pad, which is located to the side of the third screw hole.

[0082] By setting the second solder pad, the second enclosure 212 can be connected to the rear skirt 120 by welding.

[0083] It is understandable that either the third screw hole or the second pad can be used, or both can be used.

[0084] In some embodiments, please refer to Figure 2 The third enclosure 213 is formed at the intersection of the first enclosure 211 and the second enclosure 212 and extends away from the first enclosure 211 and the second enclosure 212. The third enclosure 213 is provided with a third screw connection and / or a third welding position.

[0085] The third screw connection position can satisfy the screw connection between the third enclosure plate 213 and the rear column 110 and the rear skirt plate 120. The third welding position can satisfy the screw connection between the third enclosure plate 213 and the rear column 110 and the rear skirt plate 120. The third screw connection position can be set with reference to the aforementioned first screw connection position 2111 and / or the second screw connection position. The third welding position can be set with reference to the aforementioned first welding position 2112 and / or the second welding position 2121.

[0086] In some embodiments, please refer to Figure 1 and Figure 2 The third panel 213 includes a first connecting part 2131 and a second connecting part 2132. The first connecting part 2131 is connected to the rear column 110, and the second connecting part 2132 is connected to the rear skirt panel 120.

[0087] As described above, the rear skirt 120 is connected between the rear pillar 110 and the rear skirt 120. The two are structurally different. The first connecting part 2131 and the second connecting part 2132 enable the third panel 213 to be compatible with the connection between the rear pillar 110 and the rear skirt 120.

[0088] In some specific embodiments, please refer to Figure 2 An arc transition portion 2133 is also provided between the first connecting portion 2131 and the second connecting portion 2132.

[0089] By connecting the first connecting part 2131 and the second connecting part 2132 with the arc transition part 2133, an arc transition between the first connecting part 2131 and the second connecting part 2132 can be achieved, which can avoid stress concentration and thus improve the overall structural strength and rigidity of the connecting plate 210.
