The invention belongs to the technical field of cabin frame structures, and particularly relates to a front wall upper cross beam structure and a vehicle. The front wall upper cross beam structure comprises a cross beam left joint, a cross beam right joint and a cross beam body, one end of the beam body is connected with a left A-pillar inner plate of a vehicle through a left beam connector, and the other end of the beam body is connected with a right A-pillar inner plate of the vehicle through a right beam connector. The cross beam body comprises a cross beam shell and an internal supportingstructure, the cross beam shell defines a closed cavity extending from the cross beam left connector to the cross beam right connector, the internal supporting structure is located in the closed cavity, and the internal supporting structure divides the closed cavity in the extending direction of the closed cavity. The cross beam is high in space utilization rate, low in weight, capable of meetingthe requirement for compact cabin arrangement, simple in structure and small in cross section size of the cross beam body, the overall light weight level of a vehicle can be improved, the cost is reduced, and meanwhile the collision performance, the flexural-torsional rigidity, the modal and other performance are met.

    本发明属于机舱框架结构技术领域,尤其涉及一种前围上部横梁结构及车辆。该前围上部横梁结构包括横梁左接头、横梁右接头和横梁本体;横梁本体的一端通过横梁左接头连接车辆的左A柱内板,横梁本体的另一端通过横梁右接头连接车辆的右A柱内板;横梁本体包括横梁壳体和内部支撑结构,横梁壳体围成自横梁左接头向横梁右接头延伸的封闭腔体,内部支撑结构位于封闭腔体内,内部支撑结构沿封闭腔体的延伸方向分割封闭腔体。本发明空间利用率高,重量低,满足机舱布置紧凑需求,且其结构简单,横梁本体的截面尺寸小,可以使得车辆的整体轻量化水平得到提升,在降低了成本的同时,也满足了碰撞性能、弯扭刚度及模态等性能。
