Abstract

A locking movement mechanism of an actuator comprises an actuator body and a one-way output device, wherein the one-way output device comprises a fixed shell, a driving shaft, a driven output shaft, a first driving piece and a second driving piece, and the first driving piece and the second driving piece are arranged between the driving shaft and the driven output shaft; a first linkage groove and a second linkage groove are formed in the driven output shaft, the first driving piece is fixedly connected with the driving shaft, the first driving piece is inserted into the first linkage groove, and at least part of the second driving piece is located in the second linkage groove and is in clearance fit with the second linkage groove; a driving groove is formed in the driving shaft, a locking groove is formed in the fixed shell, the second driving piece is movably arranged in the driving groove, and the second driving piece can be clamped into or separated from the locking groove under the guide of the driving groove. According to the invention, the power transmission from the driving shaft to the driven output shaft is guaranteed, and power transmission from the driven output shaft to the driving shaft is also cut off, so that the driving shaft can be effectively prevented from being driven by external force, and therefore using safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of driving devices, in particular to a locking motion mechanism applied to an actuator of a vehicle. Background technique [0002] Nowadays, with the development of the automobile industry and the increase in the popularity of automobiles, people have higher and higher requirements for the performance of automobiles, and they also pay more attention to the speed, convenience and safety of various operations of vehicles. Therefore, automobile companies It is especially important for the improvement of vehicle structure and the application of new technologies. [0003] In a complete vehicle, there are tens of thousands of parts, which are equipped with various actuators to realize intelligent control of the electric opening or closing of various parts. [0004] For example, in the small fuel door of the vehicle, in the traditional structure, the small door of the fuel filler cap or the small door of the charg...
