Description

Technical Field

[0001] The present invention relates to the technical field of automobile accessories, and in particular to an integral vehicle body frame structure and a vehicle. Background Art

[0002] With the rapid development of economy and science and technology, the automobile industry has achieved good development, and automobile manufacturers are paying more and more attention to the environmental protection, lightweight, safety, energy consumption and cost of automobiles.

[0003] The side panels of a car are structural components on the side of the vehicle body. They are a key component in vehicle body manufacturing and a vital part of the entire vehicle frame. They play a significant role in the vehicle's appearance, driving safety, and passenger comfort. They reduce adverse airflow generated during driving, increase downforce, and enhance stability at high speeds. The side panels consist of an outer panel assembly and an inner panel assembly. The outer panel assembly, located on the exterior of the vehicle body, primarily supports the outer side of the side panel, while also providing aesthetics and protection. The inner panel assembly, located on the interior of the side panel, connects to the vehicle body's supporting structure, supporting and reinforcing the vehicle.

[0004] Generally speaking, based on existing steel-aluminum hybrid vehicle body structures, the side panel inner panel assembly is welded together from the B-pillar inner panel assembly, the A-pillar upper inner panel assembly, the A-pillar lower inner panel assembly, and the rocker inner panel assembly. For example, patent document CN212950846U discloses a side panel inner panel comprising an A-pillar inner panel and a B-pillar inner panel. The A-pillar inner panel comprises a first hard zone, a first transition zone, and a first soft zone, with the first transition zone located between the first hard zone and the first soft zone. The B-pillar inner panel comprises a second hard zone, a second transition zone, and a second soft zone, with the second transition zone located between the second hard zone and the second soft zone. The B-pillar inner panel also comprises at least one welded edge soft zone. The second hard zone connects to the first soft zone, and the second soft zone connects to the rocker beam. By designing the soft zone, this solution can improve the local toughness of the side panel, ensuring proper energy absorption and deformation of the side panel structure during a side collision, and avoiding weld cracking and sheet metal breakage. Patent publication number CN215322870U discloses a side panel inner panel assembly structure for an automobile. The side panel inner panel assembly is a block structure, comprising an upper side beam inner panel, an A-pillar inner panel assembly, and a B-pillar inner panel assembly. One end of the upper side beam inner panel is connected to the side panel outer panel assembly, the other end of the upper side beam inner panel is connected to the A-pillar inner panel assembly, and the B-pillar inner panel assembly is butted against the middle of the upper side beam inner panel. The A-pillar inner panel assembly is obliquely connected to the upper side beam inner panel, and the B-pillar inner panel assembly is vertically connected to the upper side beam inner panel.
