Problems solved by technology

[0004] At present, some of the connecting rods of the rudder system linkage mechanism are separate parts, and the length cannot be adjusted. For some, it is necessary to connect all the parts of the linkage mechanism first, then test the length to be adjusted, and then remove the linkage assembly or at least release the connection at one end. Only by adjusting its length, can it be adjusted after repeated times, and the efficiency is low

Abstract

The invention discloses a connecting rod mechanism of an unmanned aerial vehicle rudder system, comprising: a steering gear rocker; a rudder rocker; The internal threads of the screw holes are of opposite rotation; and a connecting rod joint, one end of which is formed with an external threaded portion; wherein the two ends of the connecting rod are each threaded to a connecting rod joint, and for any one connecting rod joint, The external thread part is screwed into the internal screw hole for a certain length; the other end of one of the connecting rod joints is movably connected to the lower end of the rocker arm of the steering gear, and the other end of the other connecting rod joint is movably connected to the The lower end of the rudder rocker arm. This fixed structure can easily adjust the total length of the connecting rod without removing the connection between the connecting rod and the rocker arm, and the connecting rod mechanism can be adjusted in place at one time, and the joint bearing can effectively adjust the rotation sticking caused by the assembly error .

Description

technical field [0001] The invention relates to a novel connecting rod mechanism of an unmanned aerial vehicle rudder system, which can conveniently adjust the distance between the center holes of the joints at both ends of the connecting rod under the condition that all parts are connected. Background technique [0002] The linkage mechanism of the UAV rudder system is a transmission mechanism for the steering gear to drive the rudder surface to rotate, usually in the form of a four-bar linkage. The steering gear drives the rocker arm of the steering gear, the rocker arm of the steering gear drives the connecting rod assembly, and the connecting rod assembly drives the rocker arm of the steering gear to deflect the rudder surface. [0003] The length of the connecting rod assembly in the connecting rod system is generally required to be adjustable, which can adjust the installation error of the steering gear rocker arm and the rudder rocker arm. [0004] At present, some o...
