Abstract

The invention belongs to the automotive field, and provides an automobile tubular frame particularly. The automobile tubular frame is mainly composed of a bottom-layer tube support and an upper-layer tube support arranged above the bottom-layer tube support. The bottom-layer tube support and the upper-layer tube support are fixedly connected through a plurality of frame vertical beams. Specifically, the automobile tubular frame is assembled through a plurality of steel tubes according to the structure of the automobile tubular frame. The automobile tubular frame had the advantages that the refit is convenient, and the personalization customization level is high; the further developing is low in input, low in difficulty and high in yield; the structure is simple, and the production cost is low; the structure is tight, the strength is high, the rigidity is high, and the safety performance is high.

Description

technical field [0001] The invention belongs to the field of automobiles, and in particular relates to an automobile tubular frame. Background technique [0002] Traditional car frames are mostly load-bearing frames made of steel plates through stamping, welding and other processes. These frames are basically limited to the production of specific models, and it is difficult to modify the finished car, and the degree of customization is not high. Moreover, the cost of the automobile frame prepared by stamping and forming of steel plate is very high. The research and development of a new steel stamping load-bearing frame is not only expensive, but also difficult. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides an automobile tubular frame assembled from multiple steel pipes. [0004] The automobile tubular vehicle frame of the present invention comprises: [0005] The bottom pipe frame; the ...
