[0020] Please see Figure 1-5 This utility model provides a technical solution: a novel welded assembly structure for an aluminum sliding door inner panel of an automobile, including a sliding door frame 1, with an upper section 2 of the inner panel fixedly mounted on the upper end of the frame 1, a front section 3 of the inner panel fixedly mounted on one side of the frame 1, a rear section 4 of the inner panel fixedly mounted on the other side of the frame 1, and a lower section 5 of the inner panel fixedly mounted on the upper end of the frame 1. The inner panel is composed of the upper section 2, the front section 3, the rear section 4, and the lower section 5 of the inner panel. Each section is assembled into a sub-assembly of the inner panel by spot welding with aluminum. This segmented design reduces the difficulty of overall stamping and forming, reduces mold development costs, and facilitates assembly and maintenance.

[0021] As an example of this utility model, the sliding door frame 1 is made of several aluminum profile square tubes welded together by aluminum spot welding. The sliding door frame 1 is made of several aluminum profile square tubes, such as 1.8mm thick, 30mm×30mm WHS-1 T6 aluminum material, welded together by MIG welding or aluminum spot welding to form a high-strength support frame. The upper support plate 11 and the lower support plate 12 of the sliding door frame are welded on the frame 1 to further increase the overall rigidity and torsional resistance.

[0022] As an example of this utility model, a sliding door middle hinge reinforcement plate 6 is fixedly provided on the surface of the rear section 4 of the inner panel of the sliding door, and a sliding door lower hinge reinforcement plate 7, an outer handle reinforcement plate 8 and a right sliding door pin mounting reinforcement plate 9 are fixedly provided on the surface of the front section 3 of the inner panel of the sliding door.

[0023] As an example of this utility model, a plurality of frame-inner panel connecting brackets 10 are fixedly provided on the surface of the sliding door frame 1. The upper section 2, the front section 3, the rear section 4, and the lower section 5 of the inner panel of the sliding door are all fixedly connected to the frame-inner panel connecting brackets 10 by pop rivets. The middle hinge reinforcement plate 6, the lower hinge reinforcement plate 7, the outer handle reinforcement plate 8, and the right sliding door pin mounting reinforcement plate 9 are respectively welded to the front section 3 and the rear section 4 of the inner panel of the sliding door to ensure the strength of key stress points. The frame-inner panel connecting brackets 10 are fixed to the sliding door frame 1 by pop rivets, and are also welded or riveted to each section 2-5 of the inner panel of the sliding door to form a stable overall structure.

[0024] As an example of this utility model, a number of upper support plates 11 of the sliding door frame 1 are welded to the upper end, and a number of lower support plates 12 of the sliding door frame 1 are welded to the lower end. All components, including inner plates, frames, and reinforcing plates, are made of aluminum alloy materials such as 5182 O-series aluminum plates. Compared with traditional steel structures, the weight is reduced by about 18%, while meeting the requirements for rigidity and strength.

[0025] As an example of this utility model, the upper section 2, the front section 3, the rear section 4, and the lower section 5 of the inner sliding door panel are all made of aluminum. The upper section 2, the front section 3, the rear section 4, and the lower section 5 of the inner sliding door panel are fixed to the frame 1 by double fixing with blind rivets and aluminum spot welding to ensure a firm connection. The aluminum profile frame 1 serves as the core support structure, distributing the force on the door and improving the overall impact resistance.

[0026] Working principle: In use, the inner panel of the sliding door consists of the upper section 2, the front section 3, the rear section 4, and the lower section 5. Each section is assembled by spot welding aluminum to form the inner panel sub-assembly. This segmented design reduces the difficulty of overall stamping and molding, decreases mold development costs, and facilitates assembly and maintenance. The sliding door frame 1 is composed of several aluminum profile square tubes, such as 1.8mm thick, 30mm×30mm WHS-1... T6 aluminum is assembled by MIG welding or aluminum spot welding to form a high-strength support frame. The upper support plate 11 and lower support plate 12 of the sliding door frame are welded onto the frame 1 to further increase overall rigidity and torsional resistance. The middle hinge reinforcement plate 6, the lower hinge reinforcement plate 7, the outer handle reinforcement plate 8, and the right sliding door pin mounting reinforcement plate 9 are welded to the front section 3 and rear section 4 of the inner panel of the sliding door, respectively, to ensure the strength of key stress points. The frame and inner panel connecting bracket 10 are fixed to the sliding door frame 1 by pop rivets, and simultaneously to the inner panel of the sliding door. Each section 2-5 is welded or riveted to form a stable overall structure; all components, including inner panels, frames, and reinforcing plates, are made of aluminum alloy materials such as 5182O series aluminum plates, which reduces weight by about 18% compared to traditional steel structures, while meeting the requirements for rigidity and strength; the upper section 2, front section 3, rear section 4, and lower section 5 of the sliding door inner panel are double-fixed to the frame 1 by blind rivets and aluminum spot welding to ensure a firm connection. The aluminum profile frame 1 serves as the core support structure, distributing the force on the door and improving the overall impact resistance.
