Meanwhile, the part of the A-pillar lower inner plate 32 connected with the door ring reinforcing plate 2 and the part of the A-pillar lower inner plate 32 used for being connected with the front coaming are at least partially overlapped, so that the A-pillar joint 101 is connected with the door ring reinforcing plate 2 and the A-pillar lower inner plate 32 at the position connected with the front coaming, the connection strength of the A-pillar joint 101 can be enhanced, the reinforcing plate structure is not required to be additionally added at the A-pillar joint 101, and the rigidity of the side wall structure at the A-pillar joint 101 can be improved under the condition of not increasing or not increasing the weight of the whole automobile, and the torsional rigidity of the upper automobile body is further improved.

In this way, the a-pillar joint 101 is also connected to the front wall gutter main body 900, and the connection strength of the a-pillar joint 101 can be further improved.

Further, the a-pillar lower inner panel 32 is of a unitary structure. That is, the a-pillar lower inner panel 32 is not divided into upper and lower parts, and is generally manufactured by integrally molding. Therefore, the number of parts can be reduced, the manufacturing cost and the weight of the whole automobile can be reduced, and the assembly rhythm can be quickened.

Further, the roof side rail inner panel 5 and the a-pillar upper inner panel 31 are welded by using a plurality of rows of welding points (for example, two rows of welding points), and the roof side rail inner panel 5 and the B-pillar inner panel 6 are also welded by using a plurality of rows of welding points (for example, two rows of welding points). In this way, the local strength of the B-pillar joint 103 is improved.

Alternatively, as shown in conjunction with fig. 4, the door ring reinforcing plate 2 includes a first reinforcing section 21, a second reinforcing section 22, a third reinforcing section 23, a fourth reinforcing section 24, and a fifth reinforcing section 25 that are integrally connected in this order, the first reinforcing section 21 and the second reinforcing section 22 being disposed opposite the a pillar inner panel 3, respectively, the third reinforcing section 23 being disposed opposite the roof side rail inner panel 5, the fourth reinforcing section 24 and the fifth reinforcing section 25 being disposed opposite the B pillar inner panel 6, respectively, and the thicknesses of the first reinforcing section 21 and the fifth reinforcing section 25 being smaller than those of the third reinforcing section 23 and the fourth reinforcing section 24, and the thicknesses of the third reinforcing section 23 and the fourth reinforcing section 24 being smaller than those of the second reinforcing section 22.

Specifically, the first reinforcing section 21, the second reinforcing section 22, the third reinforcing section 23, the fourth reinforcing section 24, and the fifth reinforcing section 25 of the door ring reinforcing plate 2 are connected in order and disposed around the edge of the front door opening, the first reinforcing section 21, the second reinforcing section 22, and the a pillar inner panel 3 constitute an a pillar, and the fourth reinforcing section 24, the fifth reinforcing section 25, and the B pillar inner panel 6 constitute a B pillar.

Since the first reinforcing section 21 and the fifth reinforcing section 25 are also required to be connected to the lower vehicle body, which is generally stronger than the upper vehicle body, the door ring reinforcing plate 2 may be smaller in strength at the first reinforcing section 21 and the fifth reinforcing section 25, and larger in strength at the second reinforcing section 22, the third reinforcing section 23, and the fourth reinforcing section 24, that is, the thicknesses of the first reinforcing section 21 and the fifth reinforcing section 25 may be set smaller than those of the second reinforcing section 22, the third reinforcing section 23, and the fourth reinforcing section 24, wherein, in turn, since the second reinforcing section 22 is a portion where the second reinforcing section 22 is disposed opposite to the a-pillar upper inner panel 31, and is also a portion where the structural strength is weak, the door ring reinforcing plate 2 is greater in thickness at the second reinforcing section 22 than that at the third reinforcing section 23 and the fourth reinforcing section 24. The thicknesses of the first reinforcing section 21 and the fifth reinforcing section 25 may be the same or different, and similarly, the thicknesses of the third reinforcing section 23 and the fourth reinforcing section 24 may be the same or different. For example, the thicknesses of the first reinforcing section 21 and the fifth reinforcing section 25 may be set to 1.4mm, the thicknesses of the third reinforcing section 23 and the fourth reinforcing section 24 may be set to 1.6mm, and the thicknesses of the second reinforcing section 22 may be set to 1.8mm, and in practical applications, the thicknesses of the respective reinforcing sections may be adjusted as needed.

In this embodiment, the door ring reinforcing plate 2 can be divided into a plurality of reinforcing sections so as to splice the reinforcing sections with different thicknesses together in a laser splice welding mode, thereby realizing the integrated molding of the door ring reinforcing plate 2, reducing the number of parts and reducing the manufacturing cost. Meanwhile, the thicknesses of the first reinforcing section 21 and the fifth reinforcing section 25 are set to be smaller than those of the third reinforcing section 23 and the fourth reinforcing section 24, and the thicknesses of the third reinforcing section 23 and the fourth reinforcing section 24 are set to be smaller than those of the second reinforcing section 22, so that different parts of the door ring reinforcing plate 2 have different thicknesses, further have different rigidity and strength, and are convenient to set according to the strength requirements of different parts of the door ring reinforcing plate 2, and the additional addition of reinforcing plate structures to improve the strength of different parts of the door ring reinforcing plate 2 is avoided.
