[0002] The integral door inner panel (with window frame) is formed through one-piece stamping and has good strength. Its door lock assembly is usually installed directly on the door inner panel, and the door lock mounting surface is formed by the door inner panel. This structure basically does not cause too many quality problems for door inner panels made of traditional steel plates. However, for the aluminum alloy integral door inner panel structure, it is not convenient to adjust the draft angle due to the limitation of the door lock mounting surface angle. In addition, the formability of aluminum alloy sheet metal is not as good as that of steel plates. During stamping, the door lock mounting area on the B-pillar side of the door inner panel is particularly prone to wrinkling, cracking and other quality problems, resulting in a high scrap rate of parts. At the same time, it will also affect the overall structural strength of the door inner panel, and since this area is a highly visible area, it will also affect the refinement and aesthetics of the entire vehicle.

[0003] Therefore, there is an urgent need to provide a new door inner panel assembly and vehicle, which is required to be able to facilitate the adjustment of the draft angle of the door inner panel, thereby reducing quality problems such as wrinkling and cracking during the forming process of the aluminum alloy door inner panel; at the same time, it is conducive to ensuring the overall structural strength of the door inner panel, and to ensure the refinement and aesthetics of the product.
