The invention relates to an integrated door ring structure, a side wall inner beam assembly and an automobile side wall, and is applied to the field of vehicle door ring structures. The door ring comprises a door ring body and a plurality of reinforcing pieces, the door ring body comprises a column A lower section, a column A upper section, an upper door frame, a column B and a doorsill which are sequentially connected end to end, and the column A lower section, the column A upper section, the upper door frame, the column B and the doorsill are all made of thermoforming materials; all the reinforcers are arranged on the door ring main body at intervals; the door ring main body and all the reinforcing pieces jointly form a door ring original plate, and the door ring original plate is subjected to hot stamping treatment to form an integrated door ring structure. The door ring body is made of the thermal forming material, the A column lower section, the A column upper section, the upper door frame, the B column, the doorsill and the reinforcing piece are welded into a whole through laser welding and then are subjected to hot stamping treatment to form the integrated structure, and a side wall reinforcing plate assembly is replaced to achieve structural supporting; therefore, the overall strength of the automobile side wall is guaranteed, the overall part weight is reduced, and the lightweight design of an automobile can be achieved.

    本申请涉及一种一体式门环结构、侧围内梁总成及汽车侧围,应用于车辆门环结构的领域。其包括门环主体及多个加强件,门环主体包括依次首尾相连的A柱下段、A柱上段、上门框、B柱及门槛,A柱下段、A柱上段、上门框、B柱及门槛均采用热成型材料构成;全部加强件间隔布设于门环主体;门环主体与全部加强件共同构成门环原板材,门环原板材经热冲压处理后构成一体式门环结构。本申请的门环主体采用热成型材料构成,通过激光焊接将A柱下段、A柱上段、上门框、B柱、门槛及加强件焊接成整体后再通过热冲压处理成一体式结构,以替代侧围加强板总成实现结构支撑,从而在保证汽车侧围整体强度的同时减少总体零件重量,有助于实现汽车轻量化设计。
