Problems solved by technology

[0003] The landing gear is often used when the UAV takes off and lands. The current landing gear is generally fixed and cannot be folded. Sometimes it takes up a lot of space, and the current landing gear cannot weaken the landing well. Therefore, there is an urgent need for an inspection UAV with foldable undercarriage that can solve the above problems

Embodiment 1

[0020] see Figure 1~3 , in an embodiment of the present invention, a landing gear foldable inspection UAV includes a landing gear main body 4, the upper end of the landing gear main body 4 is connected to two symmetrically arranged connecting rods-20, and the connecting rods The upper end of -20 is connected with the main body of the UAV, and the landing gear main body 4 is provided with a folding landing gear mechanism, through the setting of the folding landing gear mechanism, yes, the landing gear can be collected or opened conveniently.

[0021] The specific form of the folding landing gear mechanism is not limited. In this embodiment, preferably, the folding landing gear mechanism includes a folding motor one 17 connected to the landing gear main body 4, and the rotation of the folding motor one 17 The part is connected with the reel one 1, and the reel one 1 is used for rewinding the connecting rope 2, and the four corners of the landing gear main body 4 are connected w...

Embodiment 2

[0026] This embodiment is improved on the basis of Embodiment 1. A plurality of anti-collision parts are arranged on the side and underside of the landing gear main body 4. Preferably, the anti-collision parts comprise 4 connected anti-collision balls 23, preferably, the anti-collision balls 23 are vacuum rubber balls, through the setting of the anti-collision balls 23, the impact force generated during the collision is prevented.

[0027] The working principle of the present embodiment is: the setting of the anti-collision ball 23 prevents the impact force generated when hitting.

Abstract

Disclosed is an inspection unmanned aerial vehicle with a foldable undercarriage. A folding undercarriage mechanism is arranged on an undercarriage body, when the undercarriage is put down, a folding motor I rotates to drive a winding drum I to rotate, and a connecting rope connected with the winding drum I is tensioned, so that a folding main plate is in a vertical state, and at the moment, the undercarriage is in a put-down state; when the undercarriage needs to be folded, a second folding motor rotates to drive a second winding drum to rotate, so that a connecting rope connected with the second winding drum is tensioned, the folding main plate is changed into a horizontal state, at the moment, the folding main plate is hidden in the undercarriage body, space is saved, and adjusting threaded pins penetrate through different threaded holes to be in threaded connection with moving blocks; height of a support plate and support wheels are adjusted to meet application needs of users. By arranging anti-collision balls, impact force generated during collision is prevented and the undercarriage can be conveniently folded or placed, the vehicle is simple and easy to operate and has great progress.

Description

technical field [0001] The invention relates to the related field of unmanned aerial vehicles, in particular to an inspection unmanned aerial vehicle with a foldable undercarriage. Background technique [0002] Unmanned aircraft is referred to as "unmanned aerial vehicle", and the English abbreviation is "UAV". Drones are often better suited for missions that are too "dumb, dirty or dangerous" than manned aircraft. UAVs can be divided into military and civilian uses according to their application fields; at present, they are used in aerial photography, agriculture, plant protection, miniature selfies, express delivery, disaster relief, observation of wild animals, monitoring of infectious diseases, surveying and mapping, news reports, power inspections, disaster relief, Applications in the fields of film and television shooting, romance making, etc. have greatly expanded the use of drones themselves, and developed countries are also actively expanding industry applications ...
