The invention discloses a body-in-white connecting part structure. The structure comprises a rear wall beam welding assembly and a side wall beam welding assembly, wherein the rear wall beam welding assembly and the side wall beam welding assembly are fixedly connected through a three-joint connecting piece; the rear wall beam welding assembly comprises a rear wall upper cross beam, a left rear wall longitudinal beam and a right rear wall longitudinal beam, the rear wall upper cross beam and the rear wall longitudinal beam are perpendicularly connected, and a rear wall middle reinforcing beamand a rear wall lower reinforcing beam are connected between the left rear wall longitudinal beam and the right rear wall longitudinal beam. The side wall beam welding assembly comprises a side wall upper cross beam, a side wall stand column, a side wall B column and a side wall A column, and the three-joint connecting piece is attached to the rear wall upper cross beam, the side wall upper crossbeam and the side wall stand column. And the stress structures of the side wall beam assembly and the rear wall beam assembly are more stable. According to the invention, the performance of the body-in-white bending-twisting die is greatly improved.
