Document Type and Number:
WIPO Patent Application WO/2017/202229
Kind Code:
A1
Abstract:
A high-rigidity vehicle body frame, comprising a front panel frame, a floor frame, a roof frame and two side frames. The floor frame comprises a floor front beam (11), two floor side beams (15) fixed on two ends of the floor front beam (11), and a floor support member (13) fixed between the two floor side beams (15). The side frame comprises, from front to back, a side front vertical beam (21), a side middle vertical beam (22) and a side rear vertical beam (23) which are spacedly fixed on the floor side beams (15). The roof frame comprises a roof support member (31) and two roof side beams (34), each roof side beam (34) is fixed to the side front vertical beam (21), the side middle vertical beam (22) and the side rear vertical beam (23) on a same side, and the roof support member (31) is fixed between the two roof side beams (34). The front panel frame is connected and fixed between the two roof side beams (34), and comprises a front support member (41) which is fixed on the floor front beam (11) and which has an X-shaped structure. By means of the roof support member (31), the front support member (41) and the floor support member (13), the present high-rigidity vehicle body frame can improve the lateral deformation capacity and bending deformation capacity of the vehicle body, and thereby increasing the overall rigidity of the vehicle body.
