[0041] As shown in the prior art, the rear end of the first longitudinal beam 1' is connected with the front end of the second longitudinal beam 3', so that the impact force received by the first longitudinal beam 1' is all transmitted to the second longitudinal beam 3'. In the prior art, a plurality of reinforcing members are arranged on the second longitudinal beam 3' to improve the strength of the second longitudinal beam 3' and reduce the possibility of deformation of the second longitudinal beam 3'. However, the plurality of reinforcing members increase the weight of the vehicle body structure. Figure 1 As shown in the prior art, the rear end of the first longitudinal beam 1' is connected with the front end of the second longitudinal beam 3', so that the impact force received by the first longitudinal beam 1' is all transmitted to the second longitudinal beam 3'. In the prior art, a plurality of reinforcing members are arranged on the second longitudinal beam 3' to improve the strength of the second longitudinal beam 3' and reduce the possibility of deformation of the second longitudinal beam 3'. However, the plurality of reinforcing members increase the weight of the vehicle body structure.

[0042] Figure 2 As shown in the prior art, the rear end of the first longitudinal beam 1' is connected with the front end of the second longitudinal beam 3', so that the impact force received by the first longitudinal beam 1' is all transmitted to the second longitudinal beam 3'. In the prior art, a plurality of reinforcing members are arranged on the second longitudinal beam 3' to improve the strength of the second longitudinal beam 3' and reduce the possibility of deformation of the second longitudinal beam 3'. However, the plurality of reinforcing members increase the weight of the vehicle body structure.

[0043] The first longitudinal beam 1 is used to bear the impact force from the front of the vehicle body structure, and the first branch 11 and the second branch 12 are both located at the rear end of the first longitudinal beam 1, so that the first longitudinal beam 1 has a Y-shaped structure to divide the impact force received by the first longitudinal beam 1 into two parts, one part is transmitted to the front wall 2 through the first branch 11, and the other part is transmitted to the second longitudinal beam 3 through the second branch 12, thereby reducing the impact force received by the second longitudinal beam 3. Therefore, the strength of the second longitudinal beam 3 can be reduced, and the number of reinforcing members can be reduced to reduce the weight of the vehicle body structure.

[0044] As shown in the prior art, the rear end of the first longitudinal beam 1' is connected with the front end of the second longitudinal beam 3', so that the impact force received by the first longitudinal beam 1' is all transmitted to the second longitudinal beam 3'. In the prior art, a plurality of reinforcing members are arranged on the second longitudinal beam 3' to improve the strength of the second longitudinal beam 3' and reduce the possibility of deformation of the second longitudinal beam 3'. However, the plurality of reinforcing members increase the weight of the vehicle body structure. Figure 2 Figure 3 As shown in the prior art, the rear end of the first longitudinal beam 1' is connected with the front end of the second longitudinal beam 3', so that the impact force received by the first longitudinal beam 1' is all transmitted to the second longitudinal beam 3'. In the prior art, a plurality of reinforcing members are arranged on the second longitudinal beam 3' to improve the strength of the second longitudinal beam 3' and reduce the possibility of deformation of the second longitudinal beam 3'. However, the plurality of reinforcing members increase the weight of the vehicle body structure.

[0045] The A-pillar 4 is located on the left and right sides of the front windshield, and is used to support the driver's cabin when the vehicle is hit to avoid deformation of the driver's cabin, so the strength of the A-pillar 4 is large and can bear a large impact force. The side of the front wall 2 away from the first branch 11 is connected with the A-pillar 4 to transmit the impact force to the A-pillar 4, and since the A-pillar 4 has a large strength, it can bear the impact force transmitted to the rear end of the front wall 2.

[0046] ​​As Figure 2 and Figure 3 shown, in a possible embodiment, the A-pillar 4 comprises a main body part 41 and a front side plate 42, one side of the front side plate 42 is connected with the front wall 2, and the other side is connected with the main body part 41, and along the width direction of the vehicle body structure, the cross-sectional area of the front side plate 42 is greater than that of the main body part 41.

[0047] The A-pillar 4 is a hollow columnar structure, the front side plate 42 is one side of the columnar structure, and the main body part 41 is the other side of the columnar structure, and the main body part 41 is connected with the front side plate 42 to form the A-pillar 4. Among them, the cross-sectional area of the front side plate 42 is larger, and the front wall 2 is connected with the front side plate 42, which can increase the area of the connecting surface of the front wall 2 and the A-pillar 4, and facilitate the front wall 2 to transmit the impact force to the A-pillar 4.

[0048] As Figure 2 and Figure 3 shown, in a possible embodiment, the front wall 2 is provided with a reinforcing plate 5, one end of the reinforcing plate 5 is connected with the front wall 2 and is located at the position in the front wall 2 connected with the first branch 11, so that the reinforcing plate 5 and the first branch 11 are located on both sides of the thickness direction of the plate structure, and the other end of the reinforcing plate 5 is connected with the front side plate 42 and is located at the position where the front side plate 42 is connected with the main body part 41, so that the reinforcing plate 5 and the main body part 41 are respectively located on both sides of the thickness direction of the front side plate 42.

[0049] The front wall 2 is a plate structure, and one end of the reinforcing plate 5 is respectively installed at the same position in the front wall 2 as the first branch 11, so that the first branch 11 can transmit most of the impact force to the position in the front wall 2 where the reinforcing plate 5 is arranged, thereby reducing the possibility of deformation of the front wall 2. The A-pillar 4 is a hollow columnar structure, and the front side plate 42 is one side of the columnar structure and is connected with the front wall 2, so the cross-sectional area of the front side plate 42 is larger, and the main body part 41 is the other side of the columnar structure, and the cross section thereof is a U-shaped structure, so the strength of the main body part 41 is greater than that of the front side plate 42. The other end of the reinforcing plate 5 is connected with the front side plate 42, so that the impact force in the reinforcing plate 5 can be transmitted to the main body part 41, so that the main body part 41 can absorb most of the impact force in the reinforcing plate 5.

[0050] As Figure 2 and Figure 3 shown, in a possible embodiment, along the width direction of the vehicle body structure, the side of the reinforcing plate 5 away from the first branch 11 is bent towards the main body part 41.

[0051] The first longitudinal beam 1 is spaced apart from the A-pillar 4 along the length direction of the frame, and the reinforcing plate 5 is located between the first longitudinal beam 1 and the A-pillar 4. The vehicle body structure comprises two first longitudinal beams 1, two A-pillars 4 and two reinforcing plates 5, the two first longitudinal beams 1 are spaced apart along the width direction of the frame, the two A-pillars 4 are spaced apart, and the distance between the two A-pillars 4 is greater than the distance between the two first longitudinal beams 1. The reinforcing plate 5 is bent away from the first branch 11 to the direction of the main body part 41, so that the end of the reinforcing plate 5 away from the first branch 11 can be connected with the main body part 41, so as to conduct the impact force in the reinforcing plate 5 to the main body part 41.

[0052] As shown in Figure 2 In a possible embodiment, the vehicle body structure further comprises a rocker 6, one end of the second longitudinal beam 3 is connected with the second branch 12, and the other end is connected with the rocker 6, so as to conduct the impact force in the second branch 12 to the rocker 6.

[0053] The second longitudinal beam 3 conducts the impact force in the second branch 12 to the rocker 6, and the rocker 6 is connected with the cross beam and the longitudinal beam at the rear end of the vehicle body structure, so as to absorb the impact force from the second longitudinal beam 3 or conduct the impact force to the rear end of the vehicle body structure, thereby improving the impact resistance of the vehicle body structure.

[0054] As shown in Figure 4 In a possible embodiment, the first branch 11 and the second branch 12 have an included angle, and a connecting part 13 is arranged at the position of the included angle to connect the opposite sides of the first branch 11 and the second branch 12.

[0055] The first branch 11 and the second branch 12 have an included angle, which facilitates the connection of the first branch 11 and the second branch 12 with different structures, so that the first branch 11 is connected with the front wall 2, and the second branch 12 is connected with the second longitudinal beam 3. The first longitudinal beam 1 is provided with a flange on both sides, so as to improve the strength of the first longitudinal beam 1, and at the same time provide support for the side of the first branch 11 and the second branch 12 away from each other, thereby reducing the possibility of deformation. The flange comprises a first flange and a second flange, the first flange is located on the side of the first branch 11 away from the connecting part 13, and along the thickness direction of the first longitudinal beam 1, the first flange extends in the opposite direction of the connecting part 13, so that the first flange and the connecting part 13 make the cross section of the first branch 11 into a Z-shaped structure, and the second flange is located on the side of the second branch 12 away from the connecting part 13, and along the thickness direction of the first longitudinal beam 1, the second flange extends in the same direction of the connecting part 13, so that the first flange and the connecting part 13 make the cross section of the second branch 12 into a U-shaped structure. The first flange, the second flange and the connecting part 13 provide support for the two sides of the first branch 11 and the second branch 12 respectively, which can further improve the strength of the first branch 11 and the second branch 12, and reduce the possibility of deformation.

[0056] AsFigure 4 As shown in a possible embodiment, a plurality of reinforcing ribs 14 are arranged on the connecting portion 13. The reinforcing ribs 14 can extend in the direction in which the first branch 11 points to the second branch 12, and the plurality of reinforcing ribs 14 can be arranged at intervals along the extension direction of the first longitudinal beam 1.

[0057] The reinforcing ribs 14 are located on the connecting portion 13 and protrude to one side along the thickness direction of the connecting portion 13, which can improve the strength of the connecting portion 13 and reduce the possibility of deformation of the connecting portion 13 when the first longitudinal beam 1 is impacted, thereby improving the strength of the first longitudinal beam 1.

[0058] As shown in a possible embodiment, one end of the reinforcing rib 14 extends to the first branch 11, and the other end extends to the second branch 12. Figure 4

[0059] The first branch 11 and the second branch 12 have an included angle, and the connecting portion 13 is used to connect the first branch 11 and the second branch 12, so the connecting portion 13 and the first branch 11 have an included angle, one end of the reinforcing rib 14 extends to the first branch 11, which can reduce the possibility of change of the included angle between the first branch 11 and the connecting portion 13, the connecting portion 13 and the second branch 12 also have an included angle, and the other end of the reinforcing rib 14 extends to the second branch 12, which can reduce the possibility of change of the included angle between the second branch 12 and the connecting portion 13, thereby enhancing the strength of the first longitudinal beam 1.
