Abstract

The invention discloses an automobile back door panel structure. There is a distance between the main surface of the inner panel and the outer panel. External plate connection, the upper part of the V-shaped structure starts from both sides of the window sill, and the lower part extends to the lock installation part; the top edge of the reinforcement plate at the lower part of the window sill is welded to the outer plate, and the corners on both sides of the upper part are respectively welded to the upper two sides of the V-shaped structure, and the lower part The glued surface is bonded to the outer plate, and the two sides of the bottom are welded to the inner plate through the supporting claws. The space between the bottom of the V-shaped structure and the reinforcement plate at the lower part of the window sill is the lock installation space; the inner side of the left middle reinforcement plate and the right middle reinforcement plate The upper corners are respectively welded to both sides of the reinforcing plate at the lower part of the window sill, and the inner lower corners are respectively welded to both sides of the V-shaped structure. The invention effectively reduces the stamping depth of the back door, lowers the cost, provides a larger assembly space for the back door lock, and has simple structure and light weight of the panel assembly.

Description

technical field

[0001] The invention belongs to the field of automobile exterior parts, and in particular relates to an automobile back door panel structure. Background technique

[0002] Such as figure 1 and figure 2 As shown, the current conventional automobile back door panel structure includes an inner panel (18), an outer panel (19) and a left hinge reinforcing plate (11) and a right hinge reinforcement plate (11) located between the inner panel (18) and the outer panel (19). Reinforcement plate (12), left middle reinforcement plate (13), right middle reinforcement plate (14), wiper reinforcement plate (15), outer panel support claw (16) and lock reinforcement plate (17). In the shape of the rear of the car, there is often a need to make the inclination angle of the back door glass larger and the middle of the back door protrude backward. In the conventional design, the stamping depth of the inner panel (18) is too large and the process is not feasible. There are two...
