Description

[0002] Current rail vehicle door systems are transported to the vehicle manufacturer in the form of multiple primary sub-components, and then each sub-component is installed on the vehicle body in a specific order. However, due to the deviation between the actual vehicle body and the theoretical profile, direct installation cannot guarantee the installation accuracy of the door system, and repeated adjustments are needed during installation, which greatly reduces the installation and debugging efficiency.

[0003] To simplify the measurement and adjustment steps, domestic vehicle manufacturers and door system suppliers have conducted exploratory research, such as the patent CN221213981U discloses a high-speed train plug door system and a high-speed train body, which essentially divides part of the vehicle body as an integrated framework for door system installation; the patent CN2528672Y installs the door system sealing frame on a rectangular door frame, and all door system components are integrated on the rectangular door frame. In the above-mentioned solutions, the integrated framework is used as a door system component, and each set of door system requires an integrated framework, which is costly to achieve accurate manufacturing of each integrated framework. Therefore, the deviation between the actual profile and the theoretical profile of the integrated framework still exists, and repeated installation and debugging of the door system is still unavoidable. Essentially, it only transfers the installation and debugging workload from the whole vehicle to the integrated framework; at the same time, in order to ensure the connection strength between the integrated framework and the vehicle body and the rigidity of the framework itself, the weight of the door system is greatly increased, and the packaging and transportation costs are also increased. From the perspective of the whole industry chain, the efficiency is not improved but decreased. SUMMARY
