A kind of car door and window frame structure and automobile

Abstract

In order to overcome the problems of paint cracking and welding seam fatigue caused by insufficient rigidity and strength of existing car door and window structures, the present invention provides a car door and window frame structure, including door inner panels, door outer panels, window frame front components, window A frame rear assembly, a waistline reinforcement assembly and an upper sash, the sash front assembly includes a sash front outer panel and a sash front inner panel overlapping each other, the sash front outer panel and the sash front A first cavity is formed between the inner panels at the front of the window frame, the rear assembly of the window frame includes an outer panel at the rear of the window frame and an inner panel at the rear of the window frame which overlap each other, the outer panel at the rear of the window frame and the outer panel of the window frame A second cavity is formed between the inner panels at the rear of the window frame. At the same time, the invention also discloses an automobile comprising the above-mentioned vehicle door and window frame structure. The car door and window frame structure provided by the invention can ensure sufficient connection rigidity and strength of the window frame, and avoid paint cracking and sheet metal rusting caused by solder joints and seam welding cracks.

Description

technical field [0001] The invention belongs to the technical field of automobile structures, and in particular relates to a door and window frame structure and an automobile. Background technique [0002] Generally speaking, the door and window structure not only needs to meet the basic rigidity requirements, but also be able to withstand the strength of the glass lifting and lowering load; at the same time, during the frequent closing of the door, the welding spots and seam welding at the overlap between the door window frame and the inner panel can withstand Fatigue damage caused by huge instantaneous impact force. If the rigidity of the door and window frame is not strong enough, it is easy to cause glass lift problems, vehicle sealing problems and fatigue problems of solder joints or weld seams, which in turn will lead to cracked paint and rusted sheet metal. [0003] In the prior art, there are common one-piece car doors and split-type car doors. The one-piece car doo...
