Detailed Implementation

[0033] The technical solution provided by the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1 to 16As shown, a folding-wing drone includes a drone body 2, a drone head 1 fixedly mounted at the front end of the drone body 2, and a drone tail 3 fixedly mounted at the rear end of the drone body 2. The drone body 2 includes a fuselage shell 201, and a folding wing support base 207 is longitudinally slidably mounted inside the fuselage shell 201. A pair of folding wing second supports 206 are longitudinally slidably mounted on the top front end of the folding wing support base 207. The two folding wing second supports 206 slide and cooperate with each other, with one of the folding wing second supports 206 spaced apart from the folding wing support base 207 by a certain distance. The spaced-apart folding wing second supports 206 and the folding wing support base 207 are connected by a certain distance. A compression spring is fixedly installed between the bases 207 to control the height difference between the two second folding wing brackets 206, allowing the wings to fold alternately during storage, facilitating their insertion into the drone's cabin. A first folding wing bracket 204 is longitudinally rotatably mounted on the second folding wing bracket 206. A torsion spring is fixedly installed between the first folding wing bracket 204 and the second folding wing bracket 206 to control the automatic storage of the drone's folding wings. A drone folding wing 212 is laterally rotatably mounted on the first folding wing bracket 204. An adjustment key 205 is laterally slidably mounted on the front end of the first folding wing bracket 204. A pair of support push rods 203 are horizontally rotatably installed inside the outer shell 201. A connecting rod is fixedly installed at the bottom of the support push rod 203. The connecting rod at the bottom of the support push rod 203 is hinged to the adjustment key 205 on the first bracket 204 of the folding wing at the corresponding position of the support push rod 203. A bracket adjustment plate 208 is horizontally slidably installed in the front-rear direction inside the bracket base 207. An adjustment push block 209 is vertically slidably installed at the top front end of the bracket adjustment plate 208. Push rods are fixedly installed on both sides of the top of the adjustment push block 209. The push rods on the adjustment push block 209 contact and cooperate with the support push rods 203. The first adjustment key 205 is fixedly installed at the front end of the outer shell 201. The first adjusting motor 210 has a threaded rod fixedly installed on it. The threaded rod on the first adjusting motor 210 cooperates with the lead screw of the adjusting push block 209. By starting the first adjusting motor 210, the threaded rod is driven to rotate. The rotation of the threaded rod drives the adjusting push block 209 to push the bracket adjusting plate 208 to slide inside the folding wing bracket base 207. The push rod on the adjusting push block 209 pushes the support push rod 203 to rotate inside the fuselage shell 201. When the support push rod 203 rotates, it drives the first folding wing bracket 204 to flip outward on the second folding wing bracket 206 through the connecting rod at the bottom, thus unfolding the folding wing 212 of the UAV.

[0035] like Figures 1 to 16As shown, protective baffles 202 are fixedly installed on both sides of the outer wall of the fuselage shell 201. The first folding wing bracket 204 is in contact with the protective baffles 202 to protect the first folding wing bracket 204 when the folding wing is deployed, preventing damage to the first folding wing bracket 204 from foreign objects during flight. A sliding groove is provided on the bottom inner side of the fuselage shell 201, and an adjusting ramp is installed in the sliding groove. An adjusting protrusion is fixedly installed on the bottom of the bracket adjusting plate 208. The protrusion at the bottom of the bracket adjusting plate 208 slides in contact with the ramp at the bottom of the fuselage shell 201. When the first adjusting motor 210 pushes the adjusting push block 209, the bracket is adjusted. When plate 208 slides inside folding wing bracket base 207, the cooperation between the protrusion at the bottom of bracket adjustment plate 208 and the inclined plate drives folding wing bracket base 207 to slide upward inside fuselage shell 201, driving folding wing second bracket 206 to slide upward. When folding wing second bracket 206 slides to the top of the fuselage shell 201, folding wing second bracket 206 contacts the top of the inner compartment of fuselage shell 201, compressing the folding wing second bracket 206 that was separated by a distance to the same height as the other folding wing second bracket 206, so that the two drone folding wings 212 are in the same horizontal position and can be used normally.

[0036] like Figures 1 to 16 As shown, the folding wing 212 of the drone is rotatably mounted on the outside of the corresponding first folding wing bracket 204. A second adjustment motor 211 is fixedly mounted on the other side of the first folding wing bracket 204. A gear is fixedly mounted on the second adjustment motor 211. A limit key is fixedly mounted on the other end of the first folding wing bracket 204. An adjustment limit block 214 is fixedly mounted on the folding wing 212 of the drone. A rack is fixedly mounted on the inner side of the adjustment limit block 214. The rack on the inner side of the adjustment limit block 214 meshes with the gear on the second adjustment motor 211. A limit groove is provided on the outer side of the adjustment limit block 214. The limit groove on the outer side of the adjustment limit block 214 slides and engages with the limit key on the first folding wing bracket 204 to limit the rotation range of the folding wing 212 of the drone on the first folding wing bracket 204. During the flight of the drone, by starting the second adjustment motor 211 to drive the folding wing 212 of the drone to rotate on the first folding wing bracket 204, the angle of the folding wing can be adjusted, thereby adjusting the direction and altitude of the drone during flight.

[0037] like Figures 1 to 16 As shown, an arc-shaped wind deflector 213 is slidably installed inside the bottom of the fuselage shell 201. A compression spring is fixedly installed between the arc-shaped wind deflector 213 and the fuselage shell 201. The arc-shaped wind deflector 213 is used to seal the cavity left on the fuselage shell 201 after the folding wings are unfolded, so as to prevent the cavity from affecting the stability of the UAV during flight.

[0038] like Figures 1 to 16As shown, the tail section 3 of the UAV includes a tail fin support 301, which is fixedly installed at the rear end of the fuselage shell 201. Tail fin adjustment rods 302 are laterally rotatably mounted on both sides of the tail fin support 301. A movable tail fin 303 is rotatably mounted on the tail fin adjustment rods 302. A fourth adjustment motor 308 is fixedly mounted on the tail fin adjustment rods 302 and is fixedly connected to the tail fin adjustment rods 302. A tail fin protection plate 309 is fixedly mounted on the outside of the tail fin support 301 to protect the movable tail fin 303 from damage caused by impact and shaking during transportation. A third adjustment motor 305 is fixedly installed inside the tail fin support 301, and a threaded rod is fixedly mounted on the third adjustment motor 305. An adjustment sliding plate 306 is laterally slidably mounted inside the tail fin adjustment rods 302. The adjustment sliding plate 306 is connected to the third adjustment motor 305. The tail fin adjusting rod 302 is fitted with a threaded rod and a lead screw. Adjusting grooves 307 are provided on both sides of the tail fin adjusting rod 302. Adjusting support blocks 304 are longitudinally slidably mounted on both sides of the adjusting sliding plate 306. The adjusting support blocks 304 are slidably engaged with the adjusting grooves 307. A transverse cylindrical key is fixedly mounted on the adjusting support block 304. The tail fin adjusting rod 302 is provided with a sliding groove. The cylindrical key on the adjusting support block 304 is slidably engaged with the sliding groove on the tail fin adjusting rod 302. By activating the third adjusting motor 305, the adjusting sliding plate 306 is driven to slide laterally within the tail fin support 301. Simultaneously, the adjusting grooves 307 drive the adjusting support blocks 304 to slide upwards on the adjusting sliding plate 306. The adjusting support blocks 304 drive the tail fin adjusting rod 302 to flip upwards on the tail fin support 301, unfolding the movable tail fin 303. Then, by activating the fourth adjusting motor 308, the angle of the movable tail fin 303 during flight can be adjusted.

[0039] Working principle: When the drone is activated, the first adjustment motor 210 drives the bracket adjustment plate 208 to slide laterally within the fuselage shell 201. The push rod on the adjustment push block 209 pushes the first folding wing bracket 204 to flip outward, unfolding the drone's folding wings 212. At the same time, the folding wing bracket base 207 and the bracket adjustment plate 208 slide longitudinally within the fuselage shell 201, causing the second folding wing bracket 206 to rise within the fuselage shell 201. This brings the second folding wing bracket 206 into contact with the top of the inner compartment of the fuselage shell 201, placing both second folding wing brackets 206 at the same height. This controls the two drone folding wings 212 to be in the same horizontal position. Simultaneously, the first folding wing bracket 204 slides into the protective baffle 202 for protection.

[0040] After the folding wings are deployed, the arc-shaped wind deflector 213 pops out through a compression spring to seal the cavities on both sides of the fuselage shell 201, preventing the cavities from affecting the flight stability of the UAV during flight.

[0041] By activating the third adjustment motor 305, the adjustment sliding plate 306 is driven to slide, and the adjustment support block 304 is driven to slide upward by the adjustment sliding plate 306 to unfold the movable tail fin 303. At the same time, the angle between the two movable tail fins 303 during the flight of the drone can be adjusted by activating the fourth adjustment motor 308, thereby adjusting the flight status.

[0042] When storing the drone, by storing the drone's folding wing 212 inside the fuselage shell 201 and protecting the movable tail wing 303 with the tail wing protection plate 309, the folding wing of the drone can be effectively prevented from being damaged by impact and shaking during transportation.
