Embodiment

[0044] The UAV provided in this example, such as figure 1 , figure 2As shown, it includes a body 1, a number of support bases 3 fixedly arranged on the body 1, a number of folding mechanisms 2 hinged on each support base 3 through a rotating shaft 6, and a number of folding mechanisms that drive each folding mechanism 2 to rotate; The folding mechanism 2 includes a machine arm and / or a tripod; in this example, the folding mechanism 2 is taken as a tripod as an example for specific explanation. When the folding mechanism 2 is a machine arm, the folding mechanism 2 is also equipped with a motor with a propeller, which is known to the public and will not be described in detail. The above support base 3 can be integrated with the body 1 to improve reliability and installation portability; it can also be installed on the body 1 by welding, screws, bolts, etc.

[0045] Specifically, the body 1 includes a first skeleton 1a and a second skeleton 1b; of course, it may include more s...

Abstract

In order to solve the problems that in the prior art, according to an extension and retraction system, parts are too many, the structure is complex, the occupied size is large, and design needs to be further simplified, the invention provides an unmanned aerial vehicle. The unmanned aerial vehicle comprises a vehicle body, multiple supporting bases fixedly arranged on the vehicle body, multiple folding mechanisms hinged to the supporting bases through rotating shafts and multiple retracting mechanisms driving the folding mechanisms to rotate; each retracting mechanism comprises a motor, a worm and a worm gear; the worms are fixedly mounted an output shaft of a motor, the worms and the worm gears are correspondingly engaged, the worm gears are fixedly connected with the folding mechanisms, the rotating shafts are coaxial, and therefore the worms can drive the worm gears and the folding mechanisms to rotate around axes of the rotating shafts. The unmanned aerial vehicle is simple and reliable in structure, small in occupied space, large in bearing strength, high in transmission efficiency, convenient to operate and low in cost.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to the field of unmanned aerial vehicles with retractable arms or tripods. Background technique [0002] Existing unmanned aerial vehicle except being used for military purposes at the earliest, has been used for civilian more and more now. Its structure generally includes the body (including the skeleton and the shell that covers the decoration of the skeleton), arms and tripods. When the volume of the UAV is large, it is inconvenient to transport and carry. Therefore, the arms and tripods are often configured as foldable structures, and the arms and tripods can be expanded and retracted (collectively referred to as retractable). The unfolding and folding of existing machine arms and tripods are usually carried out manually, and at the same time, locking and unlocking are carried out by a locking mechanism, so that the machine arms and tripods are in an unfolded or locked s...
