The invention relates to the technical field of commercial vehicle body-in-white beams, in particular to a beam lap joint reinforcing structure and a rear wall body-in-white beam. The reinforcing structure comprises a main connecting plate, a first limiting piece, a second limiting piece, a third limiting piece and a fourth limiting piece. The first limiting piece and the second limiting piece are arranged on one side of the main connecting plate in a spaced mode and clamped to the two sides of the first longitudinal beam. The third limiting piece and the fourth limiting piece are arranged on one side of the main connecting plate in a spaced mode and clamped to the two sides of the second longitudinal beam. The first limiting piece and the third limiting piece are clamped on the two sides of the cross beam and are clamped on the first connecting pieces extending out of one side of the first longitudinal beam and one side of the second longitudinal beam; and the second limiting piece and the fourth limiting piece are clamped on the two sides of the cross beam and are clamped on the second connecting pieces extending out of the other sides of the first longitudinal beam and the second longitudinal beam. The problems that longitudinal beams on the two sides of the cross beam are arranged in a staggered mode, longitudinal force borne by the longitudinal beams on one side is transmitted to the other side, the cross beam bears large shearing force, and the cross beam is prone to being damaged are solved, and force bearing is better facilitated when the top is pressed.
本发明涉及商用车白车身梁技术领域,具体涉及一种梁搭接加强结构和后围白车身梁。该加强结构包括:主连接板、第一限位件、第二限位件、第三限位件和第四限位件。第一限位件和第二限位件间隔设置在主连接板的一侧,卡设在第一纵梁两侧;第三限位件和第四限位件间隔设置在主连接板的一侧,卡设在第二纵梁两侧;第一限位件和第三限位件卡设在横梁的两侧,并卡设在第一纵梁和第二纵梁一侧伸出的第一连接件上;第二限位件和第四限位件卡设在横梁的两侧,并卡设在第一纵梁和第二纵梁另一侧伸出的第二连接件上。能够解横梁两侧的纵梁交错设置,导致一侧纵梁受纵向力传递到另一侧,横梁受到很大剪切力,容易破坏横梁的问题,更有利于顶部受压时承力。
