The invention discloses an automobile CD column frame structure which is characterized in that the automobile CD column frame structure comprises a C column lower reinforcing plate assembly, one side of the C column lower reinforcing plate assembly is connected with a wheel cover outer plate, the top of the C column lower reinforcing plate assembly is connected with a side wall inner plate rear upper section assembly, and the side wall inner plate rear upper section assembly is connected with the wheel cover outer plate; a wrapping frame support assembly and a seat backrest front upper supporting plate assembly which are connected with each other are arranged on the back face of the side wall inner plate rear upper section assembly, and the wrapping frame support assembly and the seat backrest front upper supporting plate assembly are both connected with the back of the C column lower reinforcing plate assembly. The C column lower reinforcing plate assembly and the package frame support assembly in the key sensitive area are connected, under the condition that the continuity and integrity of the structure are guaranteed, the modality and rigidity of the vehicle body are improved, and the overall weight of the vehicle body is reduced by 1.11 Kg. The CD column structure of the car (with the rear quarter window) is greatly simplified, the welding process is easy to implement, and the lightweight effect is obvious.
本发明公开了一种汽车CD柱框架结构,其特征在于,包括C柱下加强板总成,C柱下加强板总成一侧与轮罩外板连接,顶部与侧围内板后部上段总成连接,且侧围内板后部上段总成和轮罩外板也相互连接,侧围内板后部上段总成背面设置有相互连接的包裹架支架总成和座椅靠背前上支撑板总成,且包裹架支架总成和座椅靠背前上支撑板总成均与C柱下加强板总成背部连接。通过在关键敏感区域C柱下加强板总成和包裹架支架总成之间实现连接,保证结构连续性和完整性条件下,提升车身模态与刚度,减轻了车身整体重量1.11Kg。本发明大大简单化了轿车(带后三角窗)的CD柱结构,焊接工艺实施简单,轻量化效果明显。
