Description

[Technical Field]

[0001] This application relates to the field of vehicle body technology, and in particular to a cargo box mounting point structure and vehicle. [Background Technology]

[0002] Currently, existing cargo boxes are installed with the chassis using methods such as... Figure 1 As shown, cargo box mounting brackets 4 and cargo box mounting bracket reinforcing plates 3 are welded to the flange edges of the rear main beam sub-beam 5 and the rear main beam 7 of the vehicle frame. Due to structural strength and force transmission requirements, a sub-beam reinforcing plate 6 needs to be added to the rear main beam sub-beam 5. The cargo box mounting bracket 4 is then connected to the cargo box crossbeam 1 by connecting bolts 2. Because the force transmission path of this structure is through the flange edges of the rear main beam sub-beam 5 and the rear main beam 7 of the vehicle frame, both the cargo box mounting bracket 4 and the rear main beam sub-beam 5 require additional reinforcing plates. This results in a large number of parts and weld points, and the force transmission path is not smooth enough. Stress concentration and fatigue cracking are prone to occur at the flange edge of the cargo box mounting bracket 4 and the main beam.

[0003] Some cargo boxes are also installed with the chassis using methods such as... Figure 2 As shown, a cargo box mounting bracket 4 and a cargo box mounting bracket reinforcing plate 3 are welded onto the rear beam 7 of the vehicle frame, and a cargo box crossbeam bracket 8 is welded onto the cargo box crossbeam 1. The cargo box mounting bracket 4 and the cargo box crossbeam 1 are then connected by connecting bolts 2. Because the force transmission path of this structure is from the cargo box crossbeam 1 to the cargo box crossbeam bracket 8, then to the cargo box mounting bracket 4, and finally to the side wall of the rear beam 7 of the vehicle frame, the force transmission path is single. Therefore, the cargo box mounting bracket 4 needs to be reinforced with a cargo box mounting bracket 3, and the cargo box mounting bracket 4 needs to be designed to ensure sufficient force dissipation, resulting in a large number of parts and welding points.

[0004] Therefore, designing a novel connection structure for the installation of the cargo box and the vehicle frame to solve the problems of numerous parts, poor force transmission, and reduced cracking risk at the flange of the main beam in the existing technology is one of the urgent problems to be solved in this field.
