The high-pressure-bearing anti-deformation rear longitudinal beam comprises a rear longitudinal beam body, the rear longitudinal beam body comprises a rear longitudinal beam front section, a rear longitudinal beam middle section and a rear longitudinal beam rear section which are sequentially connected, and a first inner reinforcing plate and a second inner reinforcing plate are welded to the inner surface of the rear longitudinal beam body; the first inner reinforcing plate covers the connecting position between the rear longitudinal beam front section and the rear longitudinal beam middle section, the second inner reinforcing plate covers the connecting position between the rear longitudinal beam middle section and the rear longitudinal beam rear section, and a reinforcing piece is arranged on the inner surface of the rear longitudinal beam rear section. The rear longitudinal beam is simple in structure, low in cost and simple in welding process, and the strength and the high-pressure-bearing deformation resistance of the rear longitudinal beam can be improved.

    本发明公开了一种高承压抗变形后纵梁,包括后纵梁本体,后纵梁本体包括依次连接的后纵梁前段、后纵梁中段和后纵梁后段,后纵梁本体的内表面焊接有第一内加强板和第二内加强板,第一内加强板覆盖于后纵梁前段和后纵梁中段之间的连接处,第二内加强板覆盖于后纵梁中段和后纵梁后段之间的连接处,后纵梁后段的内表面设置有加强件。本发明的结构简单,可提高后纵梁的强度和高承压抗变形性能,且成本较低,焊接工艺简单。
