[0001] The utility model relates to the technical field of automobiles, in particular to a D-pillar structure and a non-load-bearing automobile. Background Art

[0002] The side-opening tailgate of a non-load-bearing vehicle is often equipped with a spare tire. Due to the heavy weight of the spare tire, the tailgate is prone to sinking when the vehicle is driving on bad roads. The sinking of the tailgate will cause it to be unable to open normally, and even indirectly cause problems such as failure of the tailgate sealing system to leak, looseness of the tailgate, and poor appearance of the vehicle.

[0003] For non-load-bearing vehicles with side-opening tailgates and spare tires installed on the tailgate, the D-pillar structure of the vehicle body used to install the hinge plays an important role. If the stiffness of the D-pillar is low, the tailgate is easy to sink during driving; if the stiffness of the D-pillar is high, it can greatly reduce the occurrence of problems such as the tailgate not being able to open normally, the tailgate sealing system failing and leaking, and the tailgate being loose.

[0039] The inner side of the tailgate hinge mounting plate assembly 3 is provided with a tailgate hinge upper support plate 31, a tailgate hinge lower support plate 32 and a D-pillar reinforcement plate 33 in sequence from top to bottom, and the lower part of the D-pillar reinforcement plate 33 extends to the floor rear cross beam assembly 4.

[0040] In order to strengthen the rigidity of the D-pillar structure and solve the problem of tailgate sinking, a D-pillar reinforcement plate 33 is arranged on the inner side of the tailgate hinge mounting plate assembly 3, and the lower part of the D-pillar reinforcement plate 33 is extended to the floor rear cross beam assembly 4 to ensure the integrity of the D-pillar reinforcement plate 33 in the tailgate hinge arrangement area; at the same time, the D-pillar reinforcement plate 33 is fixed to the tailgate hinge mounting plate assembly 3 by welding and screwing to achieve the vertical penetration of the D-pillar reinforcement plate 33, thereby ensuring that the entire D-pillar structure has no force transmission fault and uneven force transmission, and the rigidity of the D-pillar structure is enhanced.

[0041] In addition, by arranging the tailgate hinge upper support plate 31 and the tailgate hinge lower support plate 32 on the inner side of the tailgate hinge mounting plate assembly 3, the force transmission path of the D-pillar structure is further guaranteed to be reasonably distributed, thereby improving the overall rigidity of the D-pillar structure. That is, by improving the matching and overlapping between the internal structures of the D-pillar structure, the rigidity of each structure is strengthened as needed, thereby reducing the occurrence of the tailgate sinking phenomenon.

[0042] like Figure 1-5 The D-pillar outer panel assembly 2 and the tailgate hinge mounting plate assembly 3 are welded and fixed to form a D-pillar outer panel assembly; the D-pillar outer panel assembly and the D-pillar inner panel assembly 1 are welded and screwed to form a D-pillar reinforcement plate assembly.
