The invention discloses an automobile engine compartment assembly structure which comprises a front longitudinal beam assembly, a front baffle body, a front baffle upper cross beam and a front baffle lower cross beam connected with the front baffle upper cross beam, and the front baffle upper cross beam is provided with a first contact face and a second contact face which are connected with the front baffle body. A first cavity penetrating in the length direction of the front baffle upper cross beam is formed in the connecting position of the first contact face and the front baffle body and the connecting position of the second contact face and the front baffle body, and the front baffle lower cross beam is provided with a third contact face connected with the front baffle upper cross beam and a fourth contact face connected with the front baffle body. A second cavity penetrating in the length direction of the front baffle lower cross beam is formed in the connecting position of the third contact face and the front baffle body and the connecting position of the fourth contact face and the front baffle body. According to the automobile engine compartment assembly structure, a double-closed-section cross beam penetrating structure is achieved, the overall torsional rigidity and modality of an automobile body are improved, and meanwhile the intrusion resistance strength of collision safety can be improved. The invention further discloses an automobile.
本发明公开了一种汽车发舱总成结构,包括前纵梁总成、前挡板本体、前挡板上横梁、与前挡板上横梁连接的前挡板下横梁,前挡板上横梁具有与所述前挡板本体连接的第一接触面和第二接触面,第一接触面和第二接触面与前挡板本体的连接处形成一个沿前挡板上横梁长度方向贯穿设置的第一空腔,前挡板下横梁具有与前挡板上横梁连接的第三接触面和与前挡板本体连接的第四接触面,第三接触面和第四接触面与前挡板本体的连接处形成一个沿前挡板下横梁长度方向贯穿设置的第二空腔。本发明的汽车发舱总成结构,实现了双封闭截面横梁贯穿结构,提升汽车车身整体的扭转刚度及模态,同时还可以提升碰撞安全的抗侵入强度。本发明还公开了一种汽车。
