The invention discloses a middle channel beam lap joint structure which comprises a middle channel body. The two sides of the middle channel body extend to the middle channel left longitudinal beam and the middle channel right longitudinal beam. The middle channel body, the middle channel left longitudinal beam and the middle channel right longitudinal beam are welded and fixed on a front floor; a middle channel rear reinforcing plate, a middle channel middle reinforcing plate and a middle channel front reinforcing plate are arranged on the middle channel body; the middle channel rear reinforcing plate and the middle channel front reinforcing plate are welded to the middle channel left longitudinal beam and the middle channel right longitudinal beam on the two sides. A middle channel body extends to the outer end of a middle channel longitudinal beam, the outer side of the middle channel longitudinal beam is welded to the middle channel body and a front floor, the inner side of the middle channel longitudinal beam is welded to the middle channel body and a middle channel reinforcing support, and the middle channel reinforcing support and the middle channel longitudinal beam form a through cross section, so that the middle channel assembly structure can improve the safety collision performance; and meanwhile, the rigidity mode of the middle channel support is improved, the sensitivity of the vehicle body is reduced, and good NVH performance is obtained.

    本发明公开了一种中通道梁搭接结构,包括中通道本体;中通道本体的两侧延伸至中通道左纵梁和中通道右纵梁上;中通道本体与中通道左纵梁和中通道右纵梁进行焊接固定在前地板上;中通道本体上设置有中通道后加强板、中通道中加强板、中通道前加强板;中通道后加强板和中通道前加强板与两侧中通道左纵梁和中通道右纵梁进行焊接。通过中通道本体延伸至中通道纵梁外端,中通道纵梁外侧与中通道本体、前地板焊接,内侧与中通道本体、中通道加强支架焊接,且中通道加强支架与中通道纵梁形成贯通的截面,使得中通道总成结构在能够改善安全碰撞性能基础上,提升车身Y向刚度和模态,同时提高中通道支架的刚度模态,降低车身敏感度,获得良好的NVH性能。
