Description

[0002] Currently, rail vehicle door systems are transported to vehicle manufacturers in the form of multiple primary sub-components, and then the sub-components are installed on the vehicle body one by one in a specific order. However, due to the deviation between the actual vehicle body and the theoretical outline, direct installation cannot guarantee the installation accuracy of the door system, and repeated adjustments are required during the installation process, which greatly reduces the efficiency of installation and debugging.

[0003] In order to simplify the measurement and adjustment steps, domestic vehicle manufacturers have conducted exploratory research with door system suppliers. For example, the patent CN221213981U discloses a EMU plug door system and EMU car body, which essentially separates part of the car body as an integrated frame for door system installation; the patent CN2528672Y installs the door system sealing frame on a rectangular door frame, and the door system components are integrated into the rectangular door frame. In the above-mentioned schemes, the integrated frame is used as a door system component, and each door system must be equipped with an integrated frame. The cost of achieving precise manufacturing of each integrated frame is high, so the deviation between the actual profile of the integrated frame and the theoretical profile still exists, and the repetition of the door system installation and debugging process is still inevitable. In essence, it is just to transfer the installation and debugging workload on the whole vehicle to the integrated frame; at the same time, in order to ensure the connection strength between the integrated frame and the car body and the rigidity of the frame itself, the weight of the door system is greatly increased, and the packaging and transportation costs are increased simultaneously. From the perspective of the entire industry chain, the efficiency is reduced instead of increased. Summary of the invention
