In the present embodiment, the terms of orientation such as "bottom", "top", "peripheral edge", "center", and the like are explained based on the drawings.
In the embodiment, the modular frame longitudinal beam structure comprises a C-shaped longitudinal beam main body 1, a C-shaped longitudinal beam connecting plate 2 connected with the top of the inner wall of the longitudinal beam main body 1, and a reinforcing beam 3 arranged on the outer side of the longitudinal beam main body 1 and arranged between the longitudinal beam main body 1 and the longitudinal beam connecting plate 2; the longitudinal beam main body 1 is opposite to the C-shaped opening of the longitudinal beam connecting plate 2; the reinforcing beam 3 is L-shaped and wraps the outer side of the lower part of the longitudinal beam main body 1. Wherein, a plurality of lightening holes 21 are arranged on the longitudinal beam connecting plate 2.
In the embodiment, the longitudinal beam main body 1 is made of high-strength steel, and is formed into a C-shaped structure with a uniform cross section through rolling, and the ventral surface and the airfoil surface are provided with system part mounting hole sites and positioning holes; the main function of the longitudinal beam body 1 of the present embodiment is to provide the frame body with bending resistance and bearing capacity. The longitudinal beam connecting plate 2 is formed by stamping high-strength steel, one end of the longitudinal beam connecting plate is matched with the longitudinal beam main body in height, the other end of the longitudinal beam connecting plate is in lap joint with the reinforcing beam, the two ends of the longitudinal beam connecting plate are irregular in shape to disperse stress, the middle ventral surface of the longitudinal beam connecting plate is provided with a plurality of lightening holes with different sizes, the lightening holes are provided with flanges to increase the rigidity of the body, and meanwhile, the lightening holes provide mounting space for riveting the upper wing surface and the lower wing surface. The longitudinal beam connecting plate 2 of the embodiment mainly improves the rigidity of the frame at the installation position of the front suspension, provides a powerful supporting effect, and simultaneously plays a role in connecting and connecting the reinforcing beam with the longitudinal beam main body. The stiffening beam 3 is respectively bent and sheared into an L-shaped structure through two high-strength steel plates, the L-shaped structure is attached and riveted to the ventral surface and the airfoil surface of the longitudinal beam main body, the closed parts at the two ends of the stiffening beam form a trapezoidal section, and the bending resistance rigidity of the longitudinal beam is greatly increased. The manufacturing process is simple, and if mass production is carried out, robot welding can be adopted to ensure the consistency of products.
