Description

[0002] A drone is an unmanned aerial vehicle that is controlled by radio remote control equipment and its own program control device. It can operate without a pilot and can be operated by radio remote control or preset program control device. Its application fields are extremely wide, covering both military and civilian categories.
[0003] In use, drones are classified into different categories according to different actual needs. These include monoplane drones and tandem biplane drones. A monoplane drone is a drone that uses a single rotor or wing to fly and is usually called a single-rotor drone. A tandem biplane drone is a drone with a special layout, the core feature of which is that two sets of wings are arranged along the fuselage axis.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0042] In this embodiment, during use, the front wing 4 and the rear wing 5 can be driven to slide along the outer walls of the first guide plate 209 and the two second guide plates 2010 respectively through the connecting mechanism. At the same time, the stabilizing mechanism moves synchronously with the movement of the rear wing 5, so that the positions of the front wing 4 and the rear wing 5 can be conveniently adjusted according to actual needs.
[0043] When it is necessary to combine the front wing 4 and the rear wing 5 into one piece, the two front wings 4 and the two rear wings 5 can be brought close to each other through the combination mechanism until the two front wings 4 and the outer walls of the two rear wings 5 are respectively attached to each other, so as to achieve the purpose of convenient combination of the front wing 4 and the rear wing 5.
[0044] During this process, the stability of the front wing 4 and the rear wing 5 after they are joined can be further improved by the stabilizing mechanism. Afterwards, the positions of the front wing 4 and the rear wing 5 after they are joined can be easily adjusted according to actual needs.
[0045] When it is necessary to separate the combined forewing 4 and rearwing 5, the above operation is reversed, thereby enabling the UAV to conveniently switch between monoplane and tandem biplane modes.
[0046] In one embodiment, such as Figures 2-8 As shown, the connecting mechanism also includes: a guide component disposed on the main body 1 of the UAV;
[0047] The guiding assembly includes: a guide rod 207 disposed inside the drone body 1, and two fixing plates 208 symmetrically fixed to the outer wall of the guide rod 207. The two fixing plates 208 are located at the two ends of the guide rod 207, and both fixing plates 208 are fixedly connected to the drone body 1.
[0048] The guide rod 207 is equipped with a first drive assembly;
[0049] The first drive assembly includes two first lead screws 206 symmetrically arranged on the outside of the guide rod 207. The two first lead screws 206 are located between two fixed plates 208. The two first lead screws 206 are rotatably connected to the two fixed plates 208 through a rotating shaft. Two servo motors 205 are symmetrically installed on one end of a fixed plate 208 away from the guide rod 207.

Through the cooperation between the guide assembly and the first drive assembly, the front wing 4 and the rear wing 5 can be driven to move, and the front wing 4 and the rear wing 5 can be guided to move.

Through the cooperation of the first displacement component and the second displacement component, the positions of the front wing 4 and the rear wing 5 can be conveniently adjusted.
[0054] In one embodiment, such as Figures 2-8 As shown, the stabilizing mechanism includes: a second drive component disposed on the main body 1 of the drone;
[0055] The second drive assembly includes: a dual-head motor 303 disposed inside the main body 1 of the UAV, the dual-head motor 303 being located below the first movable sleeve 202, the outer wall of the dual-head motor 303 being symmetrically fixedly connected to two support plates 304 by bolts, both support plates 304 being fixedly connected to the first movable sleeve 202, and two second lead screws 306 being symmetrically disposed on the outer side of the dual-head motor 303, the two second lead screws 306 being fixedly connected to two output ends on the dual-head motor 303 respectively;
[0056] A moving component is provided on the second lead screw 306;
[0057] The moving component includes: a sliding sleeve 305 sleeved on the outer wall of the second lead screw 306, the sliding sleeve 305 being threadedly connected to the second lead screw 306, the sliding sleeve 305 being slidably sleeved on the outer wall of the first connecting rod 201, and two limiting sliders 307 being symmetrically fixedly connected to the inner wall of the sliding sleeve 305, both limiting sliders 307 penetrating into the interior of the first connecting rod 201, and a guide groove for the limiting sliders 307 to slide at the contact position between the first connecting rod 201 and the limiting sliders 307, the sliding sleeve 305 can be slidably limited by the cooperation between the guide groove and the limiting sliders 307;
[0058] A locking assembly is provided on the sliding sleeve 305;
[0059] The engaging assembly includes: a movable insert rod 302 fixedly connected to one end of the sliding sleeve plate 305. The movable insert rod 302 is located at the end of the sliding sleeve plate 305 near the front wing 4. A limit baffle 301 is integrally formed on the outer wall of the end of the movable insert rod 302 away from the sliding sleeve plate 305. The outer wall of the end of the movable insert rod 302 away from the sliding sleeve plate 305 is frustum-shaped. A straight groove is provided on the second connecting rod 203 for the movable insert rod 302 to slide. Through the mutual cooperation between the frustum-shaped outer wall and the straight groove, the movable insert rod 302 can be accurately inserted into the interior of the second connecting rod 203 until the movable insert rod 302 penetrates the second connecting rod 203.
[0060] The above embodiments disclose a combined-wing UAV structure that can switch between single-wing and tandem dual-wing configurations. In use, two servo motors 205 drive two first lead screws 206 to rotate. During this process, a second movable sleeve 204 slides along the outer wall of a guide rod 207 under the threaded drive of a first lead screw 206. Simultaneously, two front wings 4 slide along the outer walls of two first guide plates 209 under the drive of the second movable sleeve 204 via a second connecting rod 203. At the same time, two rear wings 5 slide along the outer walls of two first guide plates 209 and two second guide plates 2010 under the drive of the first movable sleeve 202 via a first connecting rod 201. Simultaneously, a dual-head motor 303 moves synchronously under the drive of the support plate 304 via the first movable sleeve 202. This allows for convenient adjustment of the positions of the front wings 4 and rear wings 5 according to actual needs.
[0061] When it is necessary to combine the front wing 4 and the rear wing 5 into one piece, the two servo motors 205 drive the two first lead screws 206 respectively, so that the two front wings 4 and the two rear wings 5 can approach each other until the two front wings 4 and the outer walls of the two rear wings 5 are in contact with each other, thereby achieving the purpose of conveniently combining the front wings 4 and the rear wings 5.
[0062] During this process, the movable insert rod 302, pushed by the sliding sleeve 305 under the first connecting rod 201, passes through the straight groove to penetrate the second connecting rod 203 until the outer wall of the front wing 4 contacts the outer wall of the rear wing 5. At this time, the limiting baffle 301, pushed by the movable insert rod 302, moves to the outside of the second connecting rod 203. Then, the dual-head motor 303 is started to drive the two second lead screws 306 to rotate. At the same time, the two sliding sleeves 305, driven by the threads of the two second lead screws 306, slide along the outer walls of the two first connecting rods 201 respectively. When the time limit slider 307 is driven by the sliding sleeve 305, it slides along the inner wall of the guide groove. At the same time, the limit baffle 301 moves synchronously under the drive of the sliding sleeve 305 via the moving rod 302 until the limit slider 307 contacts one side of the inner wall of the guide groove. At this time, the moving rod 302 can block the outer wall of the second connecting rod 203 through the limit baffle 301, thereby further improving the stability of the front wing 4 and the rear wing 5 during the movement after they are combined. Then, the position of the front wing 4 and the rear wing 5 after they are combined can be conveniently adjusted according to actual needs.
[0063] When it is necessary to separate the combined forewing 4 and rearwing 5, the above operation is reversed, thereby enabling the UAV to conveniently switch between monoplane and tandem biplane modes.
[0064] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
