In conventional automobile structure design, the side reinforcement often adopts a splicing structure of scattered parts, with a large number of parts and poor performance, which cannot meet the high-performance development requirements of new models. For example, a six-seater large SUV model has a higher performance requirement for side collision than other ordinary models due to its large vehicle weight.

[0073] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0074] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0075] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present application. However, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details. Example

[0076] like Figures 1 to 12 As shown, a side panel reinforcement assembly includes a side panel front section reinforcement subassembly 1, a C-pillar lower section reinforcement subassembly 2 and a side panel rear section reinforcement subassembly 3;

[0079] The side panel rear reinforcement subassembly 3 includes a C-pillar upper reinforcement 31, a CD-pillar outer panel middle connection 32 and a D-pillar upper reinforcement 33 which are connected end to end in sequence, and the D-pillar upper reinforcement 33 is also connected to a D-pillar lower reinforcement 34;

[0080] The integrated AB-pillar door ring 11 is also connected to the door sill reinforcement rear connecting piece 21 , and the side panel upper beam rear reinforcement 12 and the C-pillar lower reinforcement 22 are also connected to the C-pillar upper reinforcement 31 .

[0081] Among them, the side panel reinforcement assembly in this embodiment is located between the side panel inner panel assembly and the side panel outer panel of the vehicle body side panel assembly. It is an important component structure to ensure the rigidity performance of the vehicle body side panel, and is also an important structure to ensure the side collision performance of the vehicle body. Therefore, by adopting an integrated AB column door ring, the integrity and rigidity performance of the door ring structure are ensured at the same time, thereby realizing the integration of the door ring and improving the side collision performance of the side panel. The integrated door ring structure also effectively reduces the number of parts, thereby achieving lightweight. The side panel reinforcement assembly in this embodiment, the side panel inner panel assembly and the side panel outer panel are all formed with a cavity structure, which can effectively ensure the rigidity performance of the side panel assembly and the side collision performance of the vehicle body.

[0082] The effective connection of the C-pillar upper reinforcement 31, the CD-pillar outer panel middle connecting piece 32, the D-pillar upper reinforcement 33 and the D-pillar lower reinforcement 34 constitutes the complete structure of the side panel rear section reinforcement sub-assembly 3, which can realize the integrity of the CD-pillar area reinforcement and ensure the rigidity performance of the rear part of the side panel assembly.

[0083] The side reinforcement assembly in this embodiment is suitable for new models with larger weight and space, and is particularly suitable for six-seat large SUV models.

[0084] Exemplarily, the integrated AB-pillar door ring 11 and the rear reinforcement 12 of the side panel upper edge beam are welded and fixed; the rear connecting piece 21 of the rocker reinforcement and the lower reinforcement 22 of the C-pillar are welded and fixed; the upper reinforcement 31 of the C-pillar, the middle connecting piece 32 of the CD-pillar outer panel and the upper reinforcement 33 of the D-pillar are welded and fixed in sequence, and the upper reinforcement 33 of the D-pillar and the lower reinforcement 34 of the D-pillar are welded and fixed; the integrated AB-pillar door ring 11 and the rear connecting piece 21 of the rocker reinforcement are connected by spot welding and structural adhesive; the rear reinforcement 12 of the side panel upper edge beam and the upper reinforcement 31 of the C-pillar are connected by spot welding and structural adhesive; the lower reinforcement 22 of the C-pillar and the upper reinforcement 31 of the C-pillar are spot welded.

[0086] For example, the C-pillar upper reinforcement 31, the D-pillar upper reinforcement 33 and the D-pillar lower reinforcement 34 are stamped from ordinary steel plates, and the CD-pillar outer panel middle connector 32 is stamped from high-strength steel plates, thereby achieving the integrity of the CD-pillar area reinforcements and ensuring the rigidity performance of the rear part of the side panel assembly.

[0087] In some embodiments, in order to ensure the strength of the integrated AB-pillar door ring and achieve lightweight of the vehicle body, the A-pillar upper area 111, the A-pillar lower area 112, the B-pillar upper area 113 and the B-pillar lower area 114 of the integrated AB-pillar door ring 11 are set to structures with different thicknesses.

[0089] Exemplarily, the A-pillar upper region 111 and the A-pillar lower region 112 of the integrated AB-pillar door ring 11 are laser welded into an integral steel plate at the first welding line 4; the A-pillar upper region 111 and the B-pillar upper region 113 of the integrated AB-pillar door ring 11 are laser welded into an integral steel plate at the second welding line 5; the B-pillar upper region 113 and the B-pillar lower region 114 of the integrated AB-pillar door ring 11 are laser welded into an integral steel plate at the third welding line 6; the B-pillar lower region 114 and the A-pillar lower region 112 of the integrated AB-pillar door ring 11 are laser welded into an integral steel plate at the fourth welding line 7.

[0090] In some embodiments, in order to achieve the integrity of the door ring and ensure the side impact performance of the door ring, an integrated AB-pillar door ring 11 is formed by laser welding the sheet material and then stamping it into one piece. This can also reduce the number of individual parts and achieve lightweight body.

[0091] After testing and verification, the integrated AB-pillar door ring 11 is formed by laser welding plates of different thicknesses and then stamping them into one piece, which can reduce the number of parts by 5 and reduce the weight by more than 2kg.

[0096] For example, the upper B-pillar region 113 and the lower B-pillar region 114 of the integrated AB-pillar door ring 11 are spot-welded with the second patch plate 14 to form an integral steel plate. The integral steel plate is then integrally stamped and formed by a hot forming stamping process to form the integrated AB-pillar door ring 11.

[0097] In some embodiments, in order to ensure the integrity of the AB-pillar region reinforcement, an A-pillar upper hinge mounting reinforcement 15 and an A-pillar lower reinforcement assembly 16 are provided in the A-pillar lower region 112 of the integrated AB-pillar door ring 11 .
