The invention provides a handrail locking device and a handrail assembly.The handrail locking device comprises a main plate, a first end cover and a second end cover, the first end cover and the second end cover are fixed to the two opposite sides of the main plate respectively, a ratchet hole is formed in the main plate, and a mandrel penetrates through the ratchet hole to be rotatably supported between the first end cover and the second end cover; one end of the core shaft is used for being connected with a handrail shaft through a gear transmission mechanism arranged in the first end cover, a rotating disc is fixedly arranged in the middle of the core shaft in a sleeved mode, the rotating disc is located in a ratchet hole of the main plate and rotates along with the core shaft, and a gear ring is arranged at the other end of the core shaft in a relatively rotating and sleeved mode. The gear ring is matched with a vehicle sensing assembly arranged in the second end cover; and a compression spring and a locking pawl are arranged between the gear ring and the turntable. According to the armrest locking device, the normal folding and unfolding function of the armrest is not affected in a normal state, and when a vehicle is braked suddenly or a collision accident occurs, the armrest can be locked in time to prevent passengers from being hurt due to excessive toppling of the armrest.

    本发明提供一种扶手锁止装置及扶手总成,其中扶手锁止装置包括主板及分别固定在主板相对两侧的第一端盖和第二端盖,所述主板上开设有棘齿孔,一芯轴穿过该棘齿孔可转动地支撑于第一端盖和第二端盖之间,所述芯轴的一端通过设置于第一端盖内的齿轮传动机构用于与扶手轴相连,所述芯轴的中部固定套设有一转盘,该转盘位于所述主板的棘齿孔内并随着所述芯轴一起转动,所述芯轴的另一端可相对转动套设有一齿圈,该齿圈与设置在第二端盖内的车感组件配合;所述齿圈与所述转盘之间设有压缩弹簧和锁止棘爪。本发明提供的扶手锁止装置,在常态下不影响扶手的正常收放功能,而在车辆急刹或发生碰撞事故时,能及时锁止扶手防止扶手因过度倾倒打伤乘员。
