Abstract: A Car Door Inner Handle Base Repair Method is a technique used to repair the fracture and separation of the welding post between the car door inner handle base and the inner door panel body without the need to replace the entire car door inner panel assembly. This method involves creating an identical repair component by copying the car door inner handle base. The repair component includes multiple corresponding through-posts, aligned with the welding posts of the damaged inner door panel body and the damaged car door inner handle base. To execute the repair, the damaged inner door panel body is drilled with holes corresponding to the through-posts, and the repair component's multiple through-posts are inserted into the corresponding holes on the damaged inner door panel, securing the repair component in place using locking mechanisms.

Abstract: A method and structure for reinforcing a car tailgate handle is used to strengthen a tailgate handle that is prone to breaking. Through the steps of disassembly, measurement, production of reinforcement parts, assembly of reinforcement parts and original parts, and installation, it is possible to quickly and extensively remedy tailgate handles with mechanical structural defects that have already been sold. This method and structure offer advantages such as simplified design, reduced material usage, environmental friendliness, ease of production, and rapid mass production.

Abstract: A car tailgate handle base reinforcement and repair structure is designed to be integrated with a car tailgate handle joint. It comprises the following features: a handle base with one side being a connecting surface and the other side being an exposed surface. The connecting surface has a pivot pin on one side and an elastic pin on the opposite side. At least one reinforcement pin, placed at an appropriate location on the connecting surface, and equipped with a tab slot. A flexible tab, with one part of the tab being shaped to correspond with the tab slot's interior and the other part forming a flat spring portion. In this structure, the flexible tab is inserted into the tab slot through the connecting part, forming a connection with the reinforcement pin.

Abstract: A method and reinforcement structure of a car door outside handle, used to replace a damaged car door handle. The process involves disassembling, measuring, manufacturing reinforcing components, assembling the reinforcing parts with original components, and installation. This method allows for rapid and mass production, utilizing a structure with embedded reinforcing components to strengthen the weaker areas of the original car door outside handle. It offers advantages such as simplified structure, reduced material usage, environmental friendliness, ease of production, and efficient mass production.
