The invention discloses a doorsill reinforcer, a doorsill assembly and a manufacturing method of the doorsill reinforcer. The doorsill reinforcer comprises a reinforcer body and a reinforcing framework, the reinforcer body comprises a first reinforcing beam and a second reinforcing beam, first reinforcing cell elements are arranged in the first reinforcing beam and the second reinforcing beam, the first reinforcing cell elements extend in the second direction, and the first direction, the second direction and the third direction are perpendicular to one another; second reinforcing cell elements are arranged in the reinforcing framework and extend in the third direction. By arranging the reinforcer body and the reinforcing framework, the structural strength and rigidity of the doorsill reinforcer are improved; the first reinforcing cell elements and the second reinforcing cell elements which are perpendicular to each other are arranged in the reinforcing part body and the reinforcing framework respectively, so that the bending rigidity, the structural strength and the energy absorption efficiency of the doorsill reinforcing part in the second direction and the third direction are improved.

    本发明公开一种门槛加强件、门槛总成、门槛加强件的制造方法,包括:加强件本体和加强骨架;加强件本体包括第一加强梁和第二加强梁,第一加强梁和第二加强梁的内部均设置有第一加强胞元,第一加强胞元沿第二方向延伸,第一方向、第二方向和第三方向相互垂直;加强骨架的内部设置有第二加强胞元,第二加强胞元沿第三方向延伸。通过设置加强件本体和加强骨架,以提升门槛加强件的结构强度和刚度;通过分别在加强件本体的内部和加强骨架的内部设置相互垂直的第一加强胞元和第二加强胞元,以提升门槛加强件在第二方向和第三方向上的抗弯刚度、结构强度和吸能效率。
