摘要
A linear actuator assembly housed within a bionic digit, which comprises a base portion, an intermediate portion and an end portion; the intermediate portion pivotally connected to the base portion at one end and pivotally connected to the end portion at the opposite end. The linear actuator assembly includes a drive mechanism; a carriage mechanism having a longitudinal axis (L); a transmission member for transmitting rotational force from the drive mechanism to the carriage mechanism; and a drive member coupled to the carriage mechanism. The carriage mechanism converts the rotational force into an axial force applied to the drive member, moving the drive member along the axis as the carriage mechanism rotates. The drive member is pivotally connected to the end portion. The intermediate portion houses the linear actuator, which further includes a first thrust bearing between the carriage mechanism and the drive mechanism, and the second thrust bearing between the carriage mechanism and a seat provided within the intermediate portion, the carriage mechanism confined between the thrust bearings at each end.
