With the advancement of technology and the development of industrialization, cars have gradually become one of the indispensable means of transportation in people's lives. Cars are composed of various auto parts and accessories, including the rear door sill plate. The rear door sill refers to a plate or component installed at the entrance of the rear door of the car, usually located close to the ground inside the vehicle. Its main function is to protect the interior of the vehicle from the invasion of dirt, water and other external elements, and it can also provide stepping support for passengers when entering and exiting the vehicle. The rear door sill is usually made of wear-resistant and easy-to-clean materials to ensure durability and comfort for long-term use.

[0003] Moreover, during the installation process of the traditional rear sill plate of a car, a bracket is installed at the entrance of the rear door to support the rear sill plate, which is fixed with screws and nuts, and the rear sill plate is placed on the bracket. The rear sill plate is usually fixed to the bracket with screws, and during the installation process, one side also has to tighten the bolts. Therefore, when replacing it, it is necessary to tighten the bolts one by one, resulting in a large amount of time required to install or remove the rear sill plate, and after long-term use, it is easy to be worn out by friction from the edge of the door or frequent dragging of objects, which is time-consuming and labor-intensive, increases the complexity of the work and reduces its service life.

[0004] Therefore, it is necessary to provide a new automobile rear rocker panel assembly to solve the above-mentioned technical problems. Utility Model Content
