Abstract
This application disclosures an electric push rod automobile lifting tailgate system featuring an independent door push rod mechanism that separates the tailgate's opening/closing actions from its lifting/lowering functions. The system includes a large beam assembly, a follower arm, a lifting beam, and a bearing platform that is rotatably attached to a lifting seat. The system also incorporates a multi-link mechanism for enhanced stability, a cylindrical cam mechanism to prevent tipping at higher positions, and an indirect ground detection mechanism for precise control on various terrains. The door push rod operates independently from the lifting mechanism, reducing mechanical stress and improving durability. Additionally, the system features a dual-function connecting plate that aligns the bearing platform with the vehicle compartment at higher positions and acts as a safety barrier during loading at lower positions, ensuring secure and efficient operation.
