The embodiment of the invention relates to a front cabin roof side rail connecting structure and a vehicle, the connecting structure comprises a roof side rail assembly, and the longitudinal surface difference of the top of the roof side rail assembly is smaller than a preset value; the roof side rail assembly comprises a roof side rail assembly and a column A assembly, the right end of the roof side rail assembly is fixedly connected with the column A assembly, the roof side rail assembly is connected with the outer wall of the column A assembly to form a continuous curved surface transition wall surface, and the top of the roof side rail assembly is arranged to be a plane with low surface difference, so that a continuous smooth structure is formed. The yawing mode of the front cabin in the length direction of the front cabin is effectively improved, shaking force is dispersed, so that the NVH performance of a vehicle is effectively improved, meanwhile, a continuous curved surface transition wall face is formed after the upper edge beam assembly is connected with the outer wall of the A column assembly, stress concentration points on the upper edge beam assembly and the A column assembly are avoided, the yawing mode of the front cabin is effectively improved, and the service life of the front cabin is prolonged. And the NVH performance of the vehicle is further improved.

    本申请实施例涉及一种前机舱上边梁连接结构及车辆,连接结构包括:上边梁总成,所述上边梁总成的顶部的纵向面差小于预设值;A柱总成,所述上边梁总成的度端部与所述A柱总成固定连接,所述上边梁总成与所述A柱总成的外壁连接后形成连续曲面过渡的壁面,通过将上边梁总成的顶部设置为低面差的平面,从而形成连续的平滑结构,有效提高前机舱沿自身长度方向的横摆模态,将震动力分散,从而有效提高车辆的NVH性能,同时通过上边梁总成与所述A柱总成的外壁连接后形成连续曲面过渡的壁面,避免上边梁总成与A柱总成上出现应力集中点,有效提高前机舱纵摆模态,进一步提高车辆的NVH性能。
