Cabin door closing limiting elastic structure
The invention belongs to the field of civil airliner cabin door and fuselage interface design, and provides a cabin door closing limiting elastic structure which can be arranged on a door periphery structure in a multi-point mode. The invention relates to the cabin door closing limiting elastic structure which can solve two problems in a conventional design scheme at the same time. Firstly, the spiral actuator is elastic when pushing a cabin door to the closing position, a certain structural buffer stroke exists before the cabin door reaches the closing position, meanwhile, vibration caused by aerodynamic force of the cabin door in the service period is relieved, finally, rigid impact on the spiral actuator is reduced, and the service life of the spiral actuator can be prolonged; and secondly, during cabin door final assembly, the assembly efficiency can be improved through structural deformation design, the cost is reduced, and the requirement of interface sealing compression amount is met. The cabin door closing limiting elastic structure is simple in structure and clear in force transmission path, damage caused by hard-to-hard collision of the spiral actuator can be reduced, the service life of the spiral actuator is prolonged, meanwhile, the assembly cost can be reduced, and the assembly efficiency is improved.
本发明属于民用客机舱门与机身界面设计领域，提供了一种舱门关闭限位弹性结构，其可多点布置在门周结构上。本发明涉及一种舱门关闭限位弹性结构，可以同时解决常规设计方案中的两个问题。一是螺旋作动器推动舱门至关闭位置时是弹性的，不但在达到关闭位置前存在一定的结构缓冲行程，同时，对服役期间舱门气动力引起的震动也有所缓解，最终减小对螺旋作动器刚性冲击，可延长螺旋作动器寿命；二是舱门总装时可通过结构变形量设计提高装配效率，降低成本，并且满足界面密封压缩量要求。本发明结构简洁，传力路径清晰，不仅可以减轻螺旋作动器硬碰硬带来的损伤，延长其使用寿命，同时也可以降低装配成本，提高装配效率。
