The object of the present invention is to propose an integral side door and window frame reinforcement plate and its installation structure, which can effectively enhance the modal stiffness of the side door in the body installation state, and reduce the risk of window frame fracture failure caused by stress concentration, and the welding and assembly of the reinforcement plate is easy, and is beneficial to modular production. The integral side door and window frame reinforcement plate of the invention has a hollow quadrilateral structure and is stamped by sheet metal. The installation structure of the integral side door and window frame reinforcing plate includes the integral side door and window frame reinforcing plate, the door inner plate, the hinge reinforcing plate, the lock reinforcing plate and the outer plate reinforcing plate. The key is that the door inner plate is stamped from the lower inner plate and the upper window frame. The integral side door and window frame reinforcing plate is fixed connected with the window frame of the door inner plate through multiple welding points, and the integral side door and window frame is integrally welded. The reinforcing plates of side doors and window frames are overlapped with hinged reinforcing plates, lock reinforcing plates and outer plate reinforcing plates respectively, and welded and fixed.
【技术实现步骤摘要】
一种整体式侧门窗框加强板及其安装结构
本专利技术属于汽车结构设计
,更具体的说,本专利技术涉及一种整体式侧门窗框加强板及其安装结构。
技术介绍
汽车车门窗框是车门刚度相对薄弱的区域,而同时车门窗框附近会有较多的附件安装,尤其需要放置并容纳侧门玻璃的升降,因此车门窗框的加强对车门的设计至关重要。侧门如果刚度不足,会引起变形过大,从而导致与周围系统发生干涉,影响整车的NVH性能;并可能会引起强度和疲劳耐久问题,给驾乘人员带来安全隐患,变形过大还可能会引起一些生产试制过程中的装配问题。窗框加强板是关乎侧门整体刚度的关键结构件之一,现有的窗框加强板大多采用分散式,即对应着窗框的三条或四条边,从而对应设计相应条数的加强板。而这样的设计存在两个弊端:一是焊装不易,每块加强板之间要进行烧焊连接,同时还要与对应处窗框分别进行焊接;二是每块加强板是独立的,因而整体性较差,容易使得各块加强板之间搭接处出现应力集中而导致窗框出现断裂的风险,造成安全隐患。
技术实现思路
本专利技术的目的是提出一种整体式侧门窗框加强板及其安装结构,以有效提升侧门在车身安装状态下的模态刚度,同时也可以减小因应力集中导致的窗框断裂失效的风险,且该加强板焊装容易,有利于模块化生产。本专利技术的整体式侧门窗框加强板呈中空四边形结构,由钣金一体冲压而成,这样该窗框加强板就无需将若干块加强板焊接固定,简化了装配流程,并避免了各块加强板之间搭接处出现应力集中而导致窗框出现断裂的风险。进一步地,该整体式侧门窗框加强板的底部设置有水平加强筋,并在水平加强筋的上方均布有若干垂直加强筋,以提高下部的强度和刚度。进一步 ...
