[0072] In the D-pillar structure in the embodiments of the present application, when the D-pillar structure is stressed, the force is divided into two parts, namely the lower left side and the lower right side of the cross area of the herringbone structure, and transmitted to the lower body. When the inner reinforcement 20 of the rear wheel arch is stressed, the force can be transmitted to the upper rear side of the vehicle body through the herringbone structure and transmitted to the lower body through the middle section connecting piece 40 of the D-pillar. When the middle section connecting piece 40 of the D-pillar is stressed, the force can be transmitted to the upper front side of the vehicle body through the herringbone structure. The inner reinforcement 20 of the rear wheel arch can effectively support the middle section connecting piece 40 of the D-pillar, and the force can be transmitted to the lower body through the inner reinforcement 20 of the rear wheel arch. The force transmission path formed by the above-mentioned herringbone structure of the D-pillar structure can effectively ensure the structural stability of the vehicle.

[0073] Furthermore, the D-pillar structure is the direct connection between the roof and the body at the rear of the vehicle body. The D-pillar structure is one of the important pillars of the entire vehicle structure. In the embodiment of the present application, the D-pillar structure has the advantages of high stiffness and strength. When the vehicle is running, especially when facing bumpy and twisting roads, the D-pillar structure can effectively support and stabilize the vehicle body structure, thereby ensuring the stability and smoothness of the vehicle; it can ensure that the rear side window or the rear windshield of the vehicle does not break due to excessive force; it can also avoid a series of abnormal noise problems caused by the weakness of the D-pillar. Moreover, the D-pillar structure can ensure that when the vehicle collides, it can effectively absorb energy and resist deformation, reserve enough space for the passengers in the vehicle, and ensure the safety of the personnel.

[0074] The embodiment of the present application also discloses a vehicle, which includes a vehicle body provided with the D-pillar structure as described above.

[0075] The D-pillar structure is provided on the vehicle body. Due to the advantages of large stiffness and strength of the D-pillar structure, the vehicle body has relatively large stiffness and strength, and the vehicle can run on harsh bumpy road conditions and avoid causing deformation and abnormal noise of the vehicle structure, and ensure safety during a collision.

[0077] The force transmitted from the side wall cross member 70 is divided into two parts, namely the lower left side and the lower right side of the cross area of the chevron structure, and transmitted to the lower vehicle body. The force transmitted from the rear hub assembly 90 can be transmitted to the upper rear side of the vehicle body through the chevron structure and then transmitted to the lower vehicle body through the middle section connector 40 of the D-pillar. The force transmitted from the middle section connector 80 of the rear tailgate can be transmitted to the upper front side of the vehicle body through the chevron structure. The inner reinforcement 20 of the rear wheel arch can effectively support the middle section connector 40 of the D-pillar, and this force can be transmitted to the lower vehicle body through the inner reinforcement 20 of the rear wheel arch. The force transmission path formed by the chevron structure of the D-pillar structure can effectively ensure the structural stability of the vehicle.
