Problems solved by technology
[0003] When the UAV enters the runway from the hangar, or enters the hangar from the runway, the UAV needs to slide on the ground. The UAV usually uses one front wheel to steer, by controlling the angle of the front wheel To steer, the front wheel steering mechanism used by the existing UAV directly drives the front wheel steering through the steering gear and the connecting rod, but the accuracy of this steering mechanism is not high, and the staff needs to pay attention to whether the UAV is cheap or not. track

The present invention relates to the technical field of unmanned aerial vehicles, in particular to a worm gear and worm structure-based unmanned aerial vehicle sliding steering device, including a body, which includes a front wheel and two rear wheels, the front wheel is a steering wheel, and the front wheel A tripod is connected to the tripod, and a steering device is connected to the tripod; it includes a steering box arranged in the body, and a first stepping motor is arranged in the steering box, and the first driving wheel is connected to the first stepping motor. A first transmission shaft is provided, a first driven wheel is provided on the first transmission shaft, a first belt is provided between the first driving wheel and the first driven wheel, a first worm wheel is provided on the first transmission shaft, and the steering box A worm is provided, the first worm gear meshes with the worm, the worm protrudes to the outside of the steering box, and the worm and the tripod are fixedly connected by a fixing pin. The steering device can precisely control the rotation angle of the front wheels and the rotation speed of the front wheels, making it more convenient for the staff to control the steering of the drone.
Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle sliding steering device based on a worm gear structure. Background technique [0002] In a broad sense, UAVs are all kinds of remote-controlled aircraft that do not require a driver to board and drive. UAVs are divided into aerial photography UAVs, surveying and mapping UAVs, air combat UAVs, early warning UAVs, etc. The UAV not only played a role that cannot be ignored in the national defense force, but also played an important role in the construction of the motherland. [0003] When the UAV enters the runway from the hangar, or enters the hangar from the runway, the UAV needs to slide on the ground. The UAV usually uses one front wheel to steer, by controlling the angle of the front wheel To steer, the front wheel steering mechanism used by the existing UAV directly drives the front wheel steering through the steering gear and the c...
