The invention belongs to the technical field of vehicle body parts, and relates to a dash panel, a dash panel manufacturing method and a vehicle, the dash panel comprises an upper plate, a lower plate, a reinforcing cross beam and a patch plate, the reinforcing cross beam is connected between the upper plate and the lower plate, the patch plate is attached to the joint of the upper plate and the reinforcing cross beam, and the upper plate is connected with the reinforcing cross beam. And/or the joint of the lower plate and the reinforcing cross beam; the upper plate, the lower plate, the reinforcing cross beam and the patch plate are formed into an integrated structure in a hot stamping mode. While light weight of an automobile body is met, overall stress distribution of the dash panel during bearing can be improved, safety of the automobile during collision is improved, the integrated structure obtained through hot stamping forming does not need additional connection or sealing, the requirement for light weight of the whole automobile can be further met, and cost is reduced. And load distribution can be improved through an overall force bearing mode of the integrated structure, stress concentration is reduced, the overall strength is further improved, and the requirements for light weight and safety are met.
本发明属于车身部件技术领域,涉及一种前围板、前围板制造方法及车辆,该前围板包括上板、下板、加强横梁和补丁板,所述加强横梁连接于所述上板和所述下板之间,所述补丁板贴合于所述上板与所述加强横梁的连接处,和/或所述下板与所述加强横梁的连接处;所述上板、所述下板、所述加强横梁和所述补丁板热冲压成型为一体结构。本申请在满足车身轻量化的同时,能够改善前围板承载时的整体应力分布,提高汽车碰撞时的安全性,通过热冲压成型得到的一体结构无需额外连接或密封,既能进一步满足整车轻量化需求,又能通过一体结构的整体承力方式改善载荷分布,减少应力集中,进一步提高整体强度,有利于兼顾轻量化及安全性需求。
