Abstract

The invention discloses a local reinforcement structure of a car auto body stringer, which comprises an auto body stringer with a U-shaped section, as well as lower lining boards and upper lining boards, wherein two long edges of the lower lining boards are respectively welded on two sides of the bottom of a U-shaped groove of the auto body stringer; two long edges of the upper lining boards are respectively welded on two sides of the bottom of a U-shaped groove of the auto body stringer. A frame shaped enclosed structure is formed by transverse reinforcing ribs, transverse reinforcing projections, or longitudinal concave-convex shapes of various components provided by the invention, so that intensity needed in reinforcement is guaranteed; meanwhile, through changing heights and sizes of side wing surfaces of the lower lining boards, a uniform transition from an original structure stress to a new structure stress is achieved; at the same time, the structures of the scheme are all made in a manner of sheet metal stamping and welding, and adoption of groove shaped steel is avoided, even for press forging structures, so that weight of the local reinforcement structure is reduced; moreover, the local reinforcement structure is simple in structure and highly practical.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a partial reinforcement structure for a longitudinal beam of a car body. Background technique [0002] In the field of automobile design, it is often necessary to modify the mature automobile body structure. For example, in the design of the electric vehicle body, the existing traditional power complete body structure is often used, but due to the needs of modification, such as installing battery brackets on the body longitudinal beam, etc., it is necessary to strengthen the body longitudinal beam structure with local large loads. Due to the limited space of the longitudinal beams, it is more difficult to strengthen the structural scheme for large loads. At the same time, in actual design, it is often difficult to ensure that the reinforcement scheme is uniformly integrated with the original structure in terms of stress, and the weak area of ​​stress is often transferred to t...
