[0048] For better understanding of the technical solutions of the present application, the embodiments of the present application are described in detail below with reference to the drawings.

[0049] It should be clear that the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0050] The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used in the description of the embodiments of the present application and the appended claims, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0051] It should be understood that the term "and / or" used herein is only a description of the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A existing alone, A and B existing together, and B existing alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are in an "or" relationship.

[0052] It should be noted that the "up", "down", "left", "right" and other orientation words described in the embodiments of the present application are described from the angle shown in the drawings, and should not be understood as a limitation of the embodiments of the present application. In addition, in the context, it should also be understood that when referring to an element connected to another element "on" or "under", it can be directly connected to another element "on" or "under", or indirectly connected to another element "on" or "under" through an intermediate element.

[0053] As Figure 1 As shown in the prior art, the rear end of the vehicle body structure includes two rear beams 1' arranged at intervals, and three cross beams 2' are arranged between the two rear beams 1', the two ends of the cross beams 2' are connected with the two rear beams 1' respectively, one of the cross beams 2' is provided with a connecting portion 21', and the power battery is carried on the connecting portion 21', two longitudinal beams 3' and a connecting beam 4' between the two longitudinal beams 3' are arranged between the other two cross beams 2', the two longitudinal beams 3' and the connecting beam 4' are in an H-shaped structure, and mounting portions are arranged on the longitudinal beams 3' and the connecting beam 4' to fix other structures in the vehicle body. The number of cross beams 2' and longitudinal beams 3' between the two rear beams 1' is large, which can cause the weight of the vehicle body structure to be large.

[0054] As Figure 1 and Figure 2 As shown in the embodiments of the present application, a vehicle body structure includes a first longitudinal beam 1 and a second longitudinal beam 2, which are arranged at intervals along the width direction of the vehicle body structure. A first cross beam 3 and a second cross beam 4 are arranged between the first longitudinal beam 1 and the second longitudinal beam 2, and are arranged at intervals along the length direction of the vehicle body structure. A third longitudinal beam 5 is arranged between the first cross beam 3 and the second cross beam 4, one end of the third longitudinal beam 5 is connected with the first cross beam 3, and the other end is connected with the second cross beam 4. The vehicle body structure further includes a floor and a seat belt buckle, and the floor and the seat belt buckle are connected with the third longitudinal beam 5.

[0055] A first crossbeam 3 and a second crossbeam 4 are positioned between the first longitudinal beam 1 and the second longitudinal beam 2 to increase the torsional rigidity of the vehicle body structure and thereby enhance its ability to withstand longitudinal loads. The two rear seatbelt buckles are integrated into a single mounting base, allowing both buckles to be mounted on the third longitudinal beam 5, securing the buckles to the floor. Compared to the prior art, the vehicle body structure in this embodiment has fewer crossbeams and longitudinal beams between the first longitudinal beam 1 and the second longitudinal beam 2, thereby reducing the weight and production costs of the vehicle body structure.

[0056] In a possible embodiment, the thickness of the first longitudinal beam 1 and the second longitudinal beam 2 are both 1 mm to 1.2 mm.

[0057] The vehicle body structure includes an anti-collision beam, the ends of which are connected to a first longitudinal beam 1 and a second longitudinal beam 2, respectively. The vehicle body structure also includes two door sills 9. Along the width direction of the vehicle body structure, the spacing between the two door sills 9 is greater than the spacing between the first longitudinal beam 1 and the second longitudinal beam 2. The ends of the first and second longitudinal beams 1 and 2, which are away from the anti-collision beam, are connected to the door sill 9. Connectors 11 are provided between the first and second longitudinal beams 1 and 2 and the door sill 9. Connectors 11 are arranged obliquely along the width direction of the vehicle body structure. Taking the first longitudinal beam 1 as an example, one end of connector 11 is connected to the first longitudinal beam 1, and the other end is connected to the door sill 9. This reduces the bending angle of the first longitudinal beam 1, thereby improving the ability of the first longitudinal beam 1 to withstand longitudinal impact forces. Therefore, the thickness of the first longitudinal beam 1 can be reduced to 1 mm, 1.1 mm, 1.2 mm, etc., preferably 1.2 mm, thereby reducing the weight of the first longitudinal beam 1. Similarly, the thickness of the second longitudinal beam 2 can be reduced, thereby reducing the weight of the vehicle body structure.

[0058] In a possible embodiment, a fixing portion is provided on the door sill 9, and the power battery is installed on the fixing portion. Therefore, there is no need to provide a cross beam for carrying the power battery between the first longitudinal beam 1 and the second longitudinal beam 2, thereby reducing the weight and production cost of the vehicle body structure.

[0059] In a possible embodiment, the thickness of the door sill 9 is 1 mm to 1.2 mm.

[0060] Along the width direction of the vehicle body structure, the cross-section of the door sill 9 is in the shape of a "J" and has a semi-open cavity inside. Compared with the prior art, the depth of the cavity in the door sill 9 in the embodiment of the present application is larger, which improves the strength of the door sill 9 and reduces the possibility of its deformation. Therefore, the thickness of the door sill 9 can be reduced to 1mm, 1.1mm, 1.2mm, etc., preferably 1mm, which reduces the weight of the door sill 9 and thus reduces the weight of the vehicle body structure.

[0061] like Figure 2 、 Figure 3 and Figure 4As shown, in a possible embodiment, the vehicle body structure includes two longitudinal beam extension plates 6, which are respectively connected to two door sills 9. Reinforcements 7 are provided at both ends of the second cross beam 4, and the reinforcements 7 are connected to the longitudinal beam extension plates 6.

[0062] The connecting member 11 is connected to the door sill 9 through the longitudinal beam extension plate 6 to improve the connection strength between the connecting member 11 and the door sill 9. One side of the reinforcement 7 is welded to the second cross beam 4, and the other side is welded to the connecting member 11, which can improve the connection strength between the second cross beam 4, the connecting member 11 and the longitudinal beam extension plate 6, and thus improve the torsional rigidity of the vehicle body structure.

[0063] like Figure 4 As shown, in a possible embodiment, the vehicle body structure includes a suspension structure and a fixing member 8 , the fixing member 8 is connected to the reinforcement 7 , and a fixing hole 81 is provided on the fixing member 8 , and the suspension structure is mounted on the fixing member 8 through the fixing hole 81 .

[0064] The suspension structure transmits forces and moments between the wheels and the vehicle body. It also absorbs impact loads from uneven roads and dampens the resulting vibrations, enhancing occupant comfort. Reinforcement 7 increases the rigidity of mounting 8, further enhancing the reliability of the suspension after installation.

[0065] like Figure 5 As shown, in one possible embodiment, the third longitudinal beam 5 includes a flange 51 that extends along the length or width of the vehicle body structure, forming a "J"-shaped cross-section along the length or width of the vehicle body structure. The flange 51 includes a plurality of spaced connection points 52, and the floor panel is connected to the connection points 52.

[0066] The flanges 51 enhance the strength of the third longitudinal beam 5 and reduce its potential for deformation. Along the length of the vehicle body structure, the flanges 51 at either end connect to the first crossbeam 3 and the second crossbeam 4. Connection points 52 can be welded points, allowing the floorboard to be welded to the flanges 51 to enhance the connection strength between the floorboard and the third longitudinal beam 5. Connection points 52 can also be screw holes, adhesive points, or similar.

[0067] In a possible embodiment, the width of the flange 51 is greater than 16 mm.

[0068] The floor is welded to the flange 51. If the width of the flange 51 is less than 16 mm, the contact area between the floor and the flange 51 is small, which will affect the welding strength between the floor and the flange 51. The width of the flange 51 is greater than 16 mm, which improves the strength of the floor after connection with the third longitudinal beam 5.

[0069] like Figure 5 As shown, in a possible embodiment, the third longitudinal beam 5 includes a plurality of reinforcing ribs 53 , and the plurality of reinforcing ribs 53 are arranged at intervals on the flange 51 .

[0070] The reinforcing rib 53 is arranged on the flange 51, which can improve the strength of the flange 51, reduce the possibility of deformation of the flange 51, and improve the stability of the floor and the flange 51 after being connected.

[0071] As shown in Figure 5 In a possible embodiment, the third longitudinal beam 5 includes a main body part 54 and a mounting part 55, two ends of the main body part 54 are connected with the first transverse beam 3 and the second transverse beam 4 respectively, the mounting part 55 is located at the middle position of the main body part 54 along the extension direction of the third longitudinal beam 5, and the width of the mounting part 55 is greater than that of the main body part 54, and the seat belt buckle is connected with the mounting part 55.

[0072] In the vehicle body structure, the rear row is provided with two seats, and therefore has two seat belt buckles, and the two seat belt buckles are integrated in the same mounting member. The mounting part 55 is provided with a welding spot, and the mounting plate is welded on the mounting part 55, and the width of the mounting part 55 is greater than that of the main body part 54, which can improve the reliability of the connection between the mounting part 55 and the mounting plate. The mounting plate can improve the contact area between the mounting part 55 and the mounting member, and further improve the stability of the mounting plate after being mounted. The mounting member is connected with the mounting plate and the mounting part 55 through long bolts, which facilitates the installation of the mounting member.

[0073] The embodiment of the present application also provides a vehicle, which includes the vehicle body structure described in any one of the above, and therefore has the effects of the vehicle body structure.

[0074] The present application relates to a vehicle body structure and a vehicle, the vehicle body structure including a first longitudinal beam 1 and a second longitudinal beam 2, which are arranged at intervals along the width direction of the vehicle body structure. A first transverse beam 3 and a second transverse beam 4 are arranged between the first longitudinal beam 1 and the second longitudinal beam 2, and are arranged at intervals along the length direction of the vehicle body structure. A third longitudinal beam 5 is arranged between the first transverse beam 3 and the second transverse beam 4, one end of the third longitudinal beam 5 is connected with the first transverse beam 3, and the other end is connected with the second transverse beam 4, and the floor and the seat belt buckle are both connected with the third longitudinal beam 5, which reduces the number of transverse beams and longitudinal beams between the first longitudinal beam 1 and the second longitudinal beam 2, and further reduces the weight of the vehicle body structure and the production cost of the vehicle body structure.

[0075] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
