The invention discloses a linear actuator and a shifter. The linear actuator comprises a motor; a transmission assembly; a screw rod; a tubular telescopic member; the front pulling assembly is mounted at the end part of the tubular telescopic component through a clutch component; wherein the clutch assembly comprises a first connector, a second connector and an elastic component, the first connector and the second connector are kept relatively fixed in the circumferential direction and can relatively move in the axial direction when engaged, and the tubular telescopic component can independently rotate in the axial separation state of the first connector and the second connector. The clutch assembly is arranged between the front pulling assembly and the tubular telescopic component, and the clutch assembly is arranged to be of a structure that the first connector, the second connector and the elastic component are matched, so that if the tubular telescopic component encounters an obstacle in the retraction process, the second connector and the first connector are separated in the axial direction, and the tubular telescopic component idles; the tubular telescopic component is prevented from continuously driving an object connected to the front pull assembly to retract so as not to extrude an obstacle, and the obstacle is also prevented from damaging the linear actuator.
本发明公开了线性致动器及移位器,包括:电机;传动组件;丝杆;管状伸缩部件;前拉总成,通过离合组件安装于管状伸缩部件的端部;其中,离合组件包括第一接头、第二接头和弹性部件,第一接头和第二接头啮合时保持周向相对固定且能轴向相对移动,第一接头和第二接头轴向分离状态下,管状伸缩部件能够独立旋转。本发明通过在前拉总成和管状伸缩部件之间设置离合组件,并将离合组件设置成第一接头、第二接头和弹性部件相配合的结构,使得管状伸缩部件缩回的过程中若遇到障碍物,则第二接头与第一接头沿轴向分离,管状伸缩部件空转,避免管状伸缩部件继续带动连接在前拉总成上的物体回缩而造成对障碍物的挤压,也避免障碍物造成线性致动器的损坏。
