AI Technical Summary
Technical Problem
The existing frameless door panel matching structure has problems such as large material usage, high cost, poor limiting reliability, and insufficient appearance refinement.
Method used
By employing a precise fit between the connecting frame and the stand-up cap, Y-axis and Z-axis limiting are achieved. Combined with the overlapping lip and barb design, it replaces the traditional U-shaped wrapping structure, enhancing limiting stability and sealing effect.
Benefits of technology
Reduce material usage, lower processing and assembly costs, improve limit stability and overall vehicle appearance refinement, improve NVH performance, and prevent door panels from loosening and making abnormal noises.

Abstract
本发明属于无框车门技术领域，具体涉及一种无框内水切与门护板匹配改进结构，包括有门护板以及内水切，门护板下部设置有连接骨架，内水切上具有立帽件，所述的立帽件与连接骨架配合安装并对门户板实现Y向限位和Z向限位。本发明的优点在于摒弃传统U形包裹结构，通过连接骨架与立帽件的精准配合实现限位，大幅减少门护板材料用量，降低加工及装配成本，同时提升整车轻量化水平，构建Y向重力辅助限位与Z向倒钩卡扣限位的双重机制，配合凸点零贴设计，有效避免门护板松动、偏移，解决传统结构稳定性差的问题，提升使用可靠性，全面优化车门系统的使用性能与NVH表现。
