The present invention relates to a device for reducing bouncing of an elevator car, and provides a device for reducing bouncing of an elevator car, the device including a separate friction module which can press and come into contact with a guide rail in a state where the elevator car is stopped at a platform, so that the device: can reduce a bouncing phenomenon that may occur in the elevator car due to a frictional force between the friction module and the guide rail when a passenger gets on and off; by controlling a friction driving unit in a PWM control manner, can adjust a moving speed and a pressing force of a friction body, so as to prevent contact noise from being generated in a contact process between the friction body and the guide rail; can maximize the frictional force to improve the overall performance and quality; and can be conveniently installed even in a conventional elevator car without a structure change.

    La présente invention se rapporte à un dispositif permettant de réduire le rebond d'une cabine d'ascenseur, et fournit un dispositif pour réduire le rebond d'une cabine d'ascenseur, le dispositif comprenant un module de frottement séparé qui peut presser et venir en contact avec un rail de guidage dans un état dans lequel la cabine d'ascenseur est arrêtée au niveau d'une plateforme, de telle sorte que le dispositif : peut réduire un phénomène de rebondissement qui peut se produire dans la cabine d'ascenseur en raison d'une force de frottement entre le module de frottement et le rail de guidage lorsqu'un passager monte et descend; peut régler une vitesse de déplacement et une force de pression d'un corps de frottement, de façon à empêcher un bruit de contact d'être généré dans un processus de contact entre le corps de frottement et le rail de guidage; peut maximiser la force de frottement pour améliorer les performances globales et la qualité; et peut être installé de manière pratique même dans une cabine d'ascenseur classique sans changement de structure.

    본 발명은 엘리베이터 카의 바운싱 저감 장치에 관한 것으로, 엘리베이터 카가 승강장에 정지한 상태에서 가이드 레일에 가압 접촉할 수 있는 별도의 마찰 모듈을 구비함으로써, 마찰 모듈과 가이드 레일 사이의 마찰력에 의해 승객의 승하차시 엘리베이터 카에 발생하는 바운싱 현상을 저감할 수 있고, 마찰 구동부를 PWM 제어 방식으로 제어하여 마찰 바디의 이동 속도 및 가압력을 조절함으로써, 마찰 바디와 가이드 레일의 접촉 과정에서 발생하는 접촉 소음을 방지할 수 있고, 이와 동시에 마찰력은 최대화할 수 있어 전체적인 성능 및 품질을 향상시킬 수 있으며, 기존 엘리베이터 카에도 구조 변경 없이 편리하게 설치할 수 있는 엘리베이터 카의 바운싱 저감 장치를 제공한다.
