Embodiment 1

[0022] Car body frame, such as Figure 1 to Figure 7 As shown, it includes a bottom frame 1. The bottom frame 1 includes a bottom crossbeam 2 and a bottom crossbeam 3 perpendicular to the bottom crossbeam 2. The bottom crossbeam 3 penetrates the bottom crossbeam 2, and the bottom crossbeam 3 and the bottom crossbeam 2 stagger to form a square space , The bottom longitudinal beam 3 and the bottom cross beam 2 are provided with a first diagonal bracing reinforcement beam, the first diagonal bracing reinforcement beam is horizontally arranged on the bottom frame 1, and the strength of the bottom frame 1 is reinforced by the first diagonal bracing reinforcement beam. The two ends of a diagonal bracing reinforcement beam are connected to the diagonals of the square space. Both sides of the bottom cross beam 2 are provided with side longitudinal beams 4 connected with the bottom cross beam 2, and the side longitudinal beam 4 is provided with a first column 5 and arranged in the first ...

Abstract

The invention discloses an automobile body framework, which relates to an automobile body structure. The automobile body framework comprises a bottom frame. The bottom frame comprises bottom cross beams and bottom longitudinal beams which perpendicularly cross with the bottom cross beams; the bottom longitudinal beams run through the bottom cross beams; side longitudinal beams connected with the bottom cross beams are arranged on the two sides of the bottom cross beams; first upright columns, second upright columns and third upright columns are arranged on the side longitudinal beams, wherein the second upright columns are arranged behind the first upright columns; and the third upright columns are arranged behind the second upright columns; the upper ends of the first upright columns are provided with a mounting cross beam parallel to the corresponding bottom cross beam; the upper ends of the second upright columns are provided with a cabin upper cross beam parallel to the corresponding bottom cross beam; and upper longitudinal beams parallel to the bottom longitudinal beams are arranged on the third upright columns. Through adoption of a frame structure, the invention has the advantages that the structure of the vehicle framework is simplified, the number of parts is reduced, the structure of each framework part is simplified, expensive stamping molds and welding tools are not needed, the automobile body framework is convenient to remodel and expand, the strength and rigidity of the automobile body framework are high, the automobile body framework is convenient to design and manufacture, the production input of the automobile body framework is low and the automobile body framework is easy to remodel and reshape.

Description

Technical field [0001] The invention relates to an automobile body structure, in particular to an automobile body frame. Background technique [0002] Most car bodies on the current market are made of steel plate stamping and then welding. The technology is complicated and the process is cumbersome. It requires huge investment in stamping dies and welding tooling. Once the design is finalized, the stamping dies and tooling are involved. Model changes are not easy. Summary of the invention [0003] Aiming at the disadvantages of cumbersome process, high cost investment, and difficult modification in the prior art, the present invention provides an automobile body frame with simple process, low cost investment, and convenient modification. [0004] In order to solve the above technical problems, the present invention is solved by the following technical solutions: [0005] The car body frame includes a bottom frame. The bottom frame includes a bottom cross beam and a bottom longitudin...
