Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle technology, and in particular relates to a multi-rotor unmanned aerial vehicle. Background Technology

[0002] In today's era of rapid technological development, multi-rotor unmanned aerial vehicles (UAVs) have emerged as a highly innovative and practical aviation technology product. With the continuous progress in materials science, electronic technology, sensor technology, and automatic control theory, a solid foundation has been laid for the rise of multi-rotor UAVs.

[0003] In the existing field of multi-rotor unmanned aerial vehicle (UAV) technology, there is often a lack of storage and disassembly functions, which results in a large space occupation when the UAV is not in use and inconvenience in carrying it when going out. This shortcoming in storage and portability has greatly limited the promotion and use of multi-rotor UAVs in a wider range of scenarios. Therefore, we propose a multi-rotor UAV. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-rotor unmanned aerial vehicle that uses a rotating fixed column to drive the locking block to rotate. When the block rotates to the corresponding slot position, the fixed column is pulled upward to drive the locking block to disengage from the circular groove, thereby causing the limiting column to disengage from the circular hole two. Then, the connecting block two is manually rotated to allow it to be retracted into the connecting block, thus solving the problem of not being able to store and disassemble.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a multi-rotor unmanned aerial vehicle (UAV), comprising a UAV body, a storage mechanism on the outer wall of the UAV body, and a disassembly mechanism at the bottom of the UAV body. The storage mechanism includes a groove, with a rotating shaft rotatably connected to the inner wall of the groove. Four rotating shafts are provided in total. Each rotating shaft has a groove inside, and a circular slider is slidably connected to the inner wall of the groove. The circular slider has several circular holes inside. A cylinder is fixedly connected to the inner wall of the groove, and a telescopic rod is fixedly connected to the inner wall of the cylinder. A spring is sleeved on the outer surface of the telescopic rod. A limit post is fixedly connected to the end of the spring away from the inner wall of the cylinder. The outer surface of the limit post engages with the inner wall of the circular holes. A connecting block is fixedly connected to the outer surface of the circular slider, and a rotating shaft is fixedly connected to the connecting block. A connecting block is rotatably connected to the outer surface of the rotating shaft. A rotating shaft is rotatably connected to the top of the connecting block. Several fan blades are fixedly connected to the outer surface of the rotating shaft. A slot is provided inside the connecting block, and a circular groove is formed on the inner wall of the slot. The inner wall is fitted with a locking block, the top of which is fixedly connected to a fixing post, and the bottom of which is fixedly connected to a limiting post. Several circular holes are formed inside the connecting block two, and the inner wall of each circular hole two engages with the outer surface of the limiting post. When the drone needs to take off, the four connecting blocks are first fixed. When the connecting block is manually moved to the appropriate position, the limiting post two is inserted into the corresponding circular hole one. Due to the presence of the telescopic rod and spring one, the limiting post two is compressed, causing it to engage in the circular hole one, thus fixing the connecting block in position. Then, the connecting block two is adjusted to the appropriate position, and the fixing post is manually moved to drive the locking block into the circular groove along the locking slot. Then, the fixing post is manually rotated to rotate the locking block, causing it to engage in the circular groove, and then the limiting post engages in the circular hole two, fixing the connecting block two. This mechanism allows the drone's wings to be folded when not in use, reducing the space occupied during normal drone storage, improving space utilization, and providing convenience for the daily storage and transportation of drones.

[0007] Furthermore, the disassembly mechanism includes a connecting frame fixedly connected to the bottom of the drone body. There are two connecting frames in total, and a telescopic rod is fixedly connected to the inner wall of the connecting frame. By setting the connecting frame, it is convenient to install and disassemble the drone's landing gear.

[0008] Furthermore, a spring is sleeved on the outer surface of the telescopic rod two, and a clamping block is fixedly connected to the side of the telescopic rod two away from the inner wall of the connecting frame. There are two clamping blocks in total. By setting the clamping blocks, it is convenient to clamp the second clamping block, thereby facilitating the installation of the UAV landing gear.

[0009] Furthermore, a second sliding groove is provided inside the connecting frame, and a sliding column is slidably connected to the inner wall of the second sliding groove. By setting the sliding column, the clamping block can be moved together while the sliding column is moved.

[0010] Furthermore, the outer wall of the sliding column is fixedly connected to the outer wall of the clamping block, the outer wall of the clamping block contacts a second locking block, the bottom of the second locking block is fixedly connected to a second cylinder, and the inner wall of the second cylinder is fixedly connected to a damper. By setting the damper, excessive impact force is prevented from being generated when the drone lands, which could damage the main body of the drone.

[0011] Furthermore, a spring three is sleeved on the outer surface of the damper, and a fixed column two is fixedly connected to the side of the damper away from the locking block two. The end of the spring three away from the locking block two is fixedly connected to the outer wall of the fixed column two, and a support plate is fixedly connected to the bottom of the fixed column two. The landing gear is damped by setting the spring three to protect the main body of the drone.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model incorporates connecting blocks. When the drone needs to take off, the four connecting blocks are first fixed. When the connecting blocks are manually moved to the appropriate position, the second limiting post is inserted into the corresponding circular hole. Due to the presence of the telescopic rod and the first spring, the second limiting post is compressed, causing it to engage in the circular hole, thus fixing the connecting block in position. Then, the connecting block is adjusted to the appropriate position, and the fixing post is manually moved to drive the locking block into the circular groove. The fixing post is then manually rotated to rotate the locking block, causing it to engage in the circular groove, and the limiting post engages in the circular hole, thus fixing the connecting block. This mechanism allows the drone's wings to be folded when not in use, reducing the space occupied during normal drone storage, improving space utilization, and providing convenience for the daily storage and transportation of drones.

[0014] 2. This utility model incorporates clamping blocks. When the drone is not in use, the sliding column can be manually moved along the second slide groove, causing the clamping blocks to move along the inner wall of the connecting frame. When the two clamping blocks move away from each other, the second clamping block can be removed, thereby disassembling the support plate below the second clamping block. Simultaneously, the presence of a damper and a third spring inside the second cylinder provides shock absorption for the drone during landing. This mechanism allows the drone's landing gear to be disassembled when not in use, further improving space utilization. When the drone is needed, the landing gear can be quickly installed. Furthermore, the built-in damper and third spring in the landing gear prevent excessive impact during landing, thus avoiding damage to the main body of the drone.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5As shown, this utility model is a multi-rotor unmanned aerial vehicle (UAV), including a UAV body 101. A storage mechanism 2 is provided on the outer wall of the UAV body 101, and a disassembly mechanism 3 is provided at the bottom of the UAV body 101. The storage mechanism 2 includes a groove 201 for conveniently storing connecting blocks 208. A rotating shaft 202 is rotatably connected to the inner wall of the groove 201. Four rotating shafts 202 are provided. A sliding groove 218 is provided inside the rotating shaft 202, and a circular slider 203 is slidably connected to the inner wall of the sliding groove 218. The sliding groove 218 facilitates the sliding of the circular slider 203, allowing the groove 201 to store two connecting blocks 208. Several circular holes 201 are provided inside the circular slider 203. 4. A cylinder 205 is fixedly connected to the inner wall of the groove 201. A telescopic rod 206 is fixedly connected to the inner wall of the cylinder 205. A spring 207 is sleeved on the outer surface of the telescopic rod 206. By setting the spring 207 to compress the limiting post 217, the limiting post 217 can be inserted into the circular hole 204, thereby fixing the connecting block 208. The end of the spring 207 away from the inner wall of the cylinder 205 is fixedly connected to the limiting post 217. The outer surface of the limiting post 217 is engaged with the inner wall of the circular hole 204. A connecting block 208 is fixedly connected to the outer surface of the circular slider 203. A rotating shaft 209 is fixedly connected to the connecting block 208. The rotating shaft 209 facilitates the rotation of the circular hole 220, allowing the circular hole 220 to be fixedly inserted into the circular hole 220. 220 can be stored inside the connecting block 208. The outer surface of the rotating shaft 209 is rotatably connected to the connecting block 210. The top of the connecting block 210 is rotatably connected to the rotating shaft 3 211. Several fan blades 212 are fixedly connected to the outer surface of the rotating shaft 3 211. The connecting block 208 has a slot 219 inside. The slot 219 facilitates the lifting of the fixing post 215 to disengage the locking block 214 from the circular groove 213. The inner wall of the slot 219 has a circular groove 213. The inner wall of the circular groove 213 is engaged with the locking block 214. The top of the locking block 214 is fixedly connected to the fixing post 215. The bottom of the locking block 214 is fixedly connected to the limiting post 216. The limiting post 216 facilitates the connection of the connecting block 210. For fixing, the connecting block 210 has several round holes 220 inside. The inner wall of the round holes 220 is engaged with the outer surface of the limiting post 216. The disassembly mechanism 3 includes a connecting frame 301 fixedly connected to the bottom of the drone body 101. There are two connecting frames 301. The inner wall of the connecting frame 301 is fixedly connected to a telescopic rod 302. The connecting frame 301 facilitates the installation and disassembly of the landing gear at the bottom. The outer surface of the telescopic rod 302 is fitted with a spring 303. The side of the telescopic rod 302 away from the inner wall of the connecting frame 301 is fixedly connected to a clamping block 304. There are two clamping blocks 304. The clamping blocks 304 clamp the locking block 307 to fix the support plate 312.

[0026] Manually rotate the fixing post 215 to align it with the slot 219 in the circular groove 213, then pull the fixing post 215 upward to drive the slot 214 into the slot 219, thereby causing the limiting post 216 to disengage from the second circular hole 220. Then rotate the second connecting block 210 to retract it into the connecting block 208. Then manually push the second limiting post 217 upward to disengage it from the first circular hole 204. Then adjust the position of the connecting block 208 so that it is retracted into the groove 201, so that the drone does not occupy too much space when it is not in use.

[0027] The connecting frame 301 has a second sliding groove 306 inside. A sliding column 305 is slidably connected to the inner wall of the second sliding groove 306. The outer wall of the sliding column 305 is fixedly connected to the outer wall of the clamping block 304. The outer wall of the clamping block 304 contacts a second locking block 307. By setting the second sliding groove 306, the sliding column 305 can be moved in the second sliding groove 306, thereby driving the clamping block 304 to move. The bottom of the second locking block 307 is fixedly connected to a second cylinder 309. A damper 308 is fixedly connected to the inner wall of the second cylinder 309. The damper 308 is set to prevent the drone from being damaged by too much impact when it lands.

[0028] Manually move the sliding column 305 along the second slide groove 306 to move the clamping block 304 inside the connecting frame 301, pressing the telescopic rod 302 and the spring 303, and then remove the second clamping block 307 from the two clamping blocks 304, thereby disassembling the drone landing gear.

[0029] A spring 310 is fitted on the outer surface of the damper 308. A fixing post 311 is fixedly connected to the side of the damper 308 away from the second locking block 307. The end of the spring 310 away from the second locking block 307 is fixedly connected to the outer wall of the fixing post 311. A support plate 312 is fixedly connected to the bottom of the fixing post 311. The spring 310 is used to buffer the force generated when the drone lands.

[0030] When the drone lands, it impacts the support plate 312, causing the fixed column 311 to move. This causes the damper 308 and spring 310 to be compressed. The damper 308 and spring 310 absorb most of the impact force, preventing the drone body from being damaged by too much impact.

[0031] One specific application of this embodiment is:

[0032] When the drone needs to take off, firstly, the four connecting blocks 208 are fixed. When the connecting blocks 208 are manually moved to the appropriate position, the limiting post 217 is inserted into the corresponding circular hole 204. Due to the presence of the telescopic rod 206 and the spring 207, the limiting post 217 is compressed, causing it to engage in the circular hole 204, thus fixing the connecting block 208 in position. Then, the connecting block 210 is adjusted to the appropriate position, and then the fixing post 215 is manually moved to drive the locking block 214 into the circular groove 213 along the slot 219. Then, the fixing post 215 is manually rotated to rotate the locking block 214, causing it to engage in the circular groove 213. The limiting post 216 is inserted into the second circular hole 220 to fix the second connecting block 210. When it needs to be stored, first rotate the fixing post 215 to rotate the locking block 214. When it rotates to the corresponding locking slot 219, pull the fixing post 215 upward to disengage the locking block 214 from the circular groove 213, thereby causing the limiting post 216 to disengage from the second circular hole 220. Then manually rotate the second connecting block 210 to retract it into the connecting block 208. Next, push the second limiting post 217 upward to move it away from the first circular hole 204. Then manually rotate the connecting block 208 to retract it above the groove 201. Repeat the same process for the other connecting block 208. The drone is stored below the groove 201. This mechanism allows the drone's wings to be folded away when not in use, reducing the space occupied during normal storage and improving space utilization. This provides convenience for the daily storage and transportation of the drone. When the drone is not in use, the sliding column 305 is manually moved along the second groove 306, which in turn moves the clamping block 304 along the inner wall of the connecting frame 301. When the two clamping blocks 304 move away from each other, the second clamping block 307 clamped between the two clamping blocks 304 can be removed, thereby disassembling the support plate 312 below the second clamping block 307. At the same time, the presence of a damper 308 and a spring 310 inside the second cylinder 309 can help to prevent the drone from landing. To provide shock absorption for the drone, when the drone lands, the support plate 312 will press upwards, thereby moving the fixed column 311 and pressing the damper 308 and the spring 310. The reaction force generated by the damper 308 and the spring 310 will press the fixed column 311 in the opposite direction, so that the drone body 101 will not be subjected to too much impact force. This mechanism allows the drone landing gear to be disassembled when the drone is not in use, which can further improve space utilization. At the same time, when the drone is needed, the landing gear can be quickly installed. The landing gear has built-in dampers 308 and spring 310, which will not generate too much impact force when the drone lands, so as not to damage the drone body 101.
