More specifically, a single-sided welding method is adopted between the first flanging 301 and the second bending surface 202 through the through hole 101 to ensure the appearance is beautiful.

[0094] The through hole 101 is a strip-shaped hole, and the length direction of the through hole 101 is parallel to the vehicle X-direction, which is convenient for the welder to weld the first flanging 301 and the second bending surface 202 along the vehicle X-direction. The setting of the through hole 101 can avoid the generation of pits caused by the clamping of the welding tongs, thus affecting the appearance quality.

[0095] A flanging is provided at the edge of the through hole 101, which can prevent the through hole 101 from deforming or cracking under force.

[0096] A single-sided welding method is adopted for both the first bending surface 201 and the connecting portion 102, and the reinforcement plate 300 and the outer side panel 200, so as to ensure the appearance is beautiful.

[0097] More specifically, a weight-reducing hole is formed in the outer side panel, which can reduce the vehicle weight.

[0098] Embodiment 5

[0099] This embodiment provides a vehicle, including the vehicle B-pillar structure described in any one of the above embodiments.
