When performing different tasks, drones can carry relevant work items as needed by using a cargo rack.
[0003] Existing racks typically use bolts to secure them to drones, and the assembly and disassembly process is quite cumbersome. Existing racks generally transport items together in a mixed manner, making it inconvenient to categorize items according to type and size. Utility Model Content
[0004] The purpose of this invention is to provide a drone cargo rack that solves the problems of cumbersome assembly and disassembly processes in existing cargo racks, and the fact that existing cargo racks generally mix the items they carry together for transportation, making it inconvenient to classify them according to item type and volume.
[0005] The specific technical solution adopted in this utility model is as follows:
[0006] A drone cargo rack, comprising:
[0007] The drone body has symmetrical support legs fixedly installed at its bottom;
[0008] The cargo-carrying mechanism is stacked at the bottom of the drone body, and the cargo-carrying mechanism facilitates the classification and placement of items according to the type and volume of the items being carried.
[0009] Limiting rods are provided inside the loading mechanism. The limiting rods are spaced apart from each other to facilitate the installation and disassembly of the loading mechanism.
[0010] A drive assembly is disposed on the left and right sides of the loading mechanism, and the drive assembly is used to drive the limit rods away from each other;
[0011] A magnetic suction assembly is disposed inside the loading mechanism. The magnetic suction assembly, together with the driving assembly, is used to drive the limiting rods to move closer to each other.
[0012] In a preferred embodiment, the four corners of the bottom surface of the drone body are fixedly provided with first inserts.
[0013] In a preferred embodiment, the cargo-carrying mechanism includes a container, slots, second rods, and vertical slots. The container is attached to the bottom surface of the drone body. Slots are provided at the four corners of the top surface of the container. Second rods are fixedly provided at the four corners of the bottom surface of the container. Both the first rod and the second rod are adapted to the slots. The first rod and the second rod are slidably connected to the container through the slots.
[0014] In a preferred embodiment, the container is provided with a first sliding groove for adapting to the limiting rod. The limiting rod is slidably connected to the container through the first sliding groove. The front and rear ends of the first sliding groove are respectively connected to the slot. The outer sides of the first and second inserts are provided with limiting grooves for adapting to the limiting rod. The limiting rod is slidably connected to the first and second inserts through the limiting grooves respectively.
[0015] In a preferred embodiment, the drive assembly includes a knob, anti-slip texture, a transmission gear, a rack, a connecting rod, a top plate, and an inclined plate. Symmetrical knobs are rotatably connected to the left and right sides of the container. Anti-slip texture is provided on the outer side of each knob. A rotating shaft is fixedly installed on the side of the knob closest to the container. Symmetrical mounting slots are provided inside the container. The rotating shaft passes through the container to the inside of the mounting slot and is rotatably connected to the container. A transmission gear is fixedly installed on the side of the rotating shaft away from the knob. The left and right sides of the transmission gear are rotatably connected to the inner wall of the mounting slot, respectively. A rack meshes with the outer side of the transmission gear. The left and right sides of the rack are slidably connected to the inner wall of the mounting slot, respectively. A connecting rod is fixedly installed on the top surface of the rack. A second sliding groove adapted to the connecting rod is provided inside the container. The connecting rod is slidably connected to the container through the second sliding groove. A top plate is fixedly installed on the top surface of the connecting rod. A third sliding groove adapted to the top plate is provided inside the container. The top plate is slidably connected to the container through the third sliding groove. Inclined plates are fixedly installed on the sides of the limiting rods that are close to each other.
[0016] In a preferred embodiment, the magnetic attraction assembly includes a permanent magnet and an iron block. The permanent magnet is fixedly disposed on the top surface inside the first chute, and the iron block is fixedly disposed on the side of the inclined plate near the permanent magnet.
[0017] The technical effects achieved by this utility model are as follows:
[0018] This utility model, by setting up a cargo-carrying mechanism, allows multiple cargo-carrying mechanisms to be stacked and installed at the bottom of the drone body, which can facilitate the classification and storage of items according to the type and volume of the items being carried.
[0019] This utility model, by setting a limiting rod and a driving component, rotates the knob to drive the rotating shaft and the transmission gear to rotate. The rotation of the transmission gear drives the rack to move upward. The movement of the rack drives the connecting rod and the top plate to move upward. The movement of the top plate drives the inclined plate to move in a direction away from each other, thereby driving the limiting rod to move away from each other and engage with the inside of the limiting groove. This makes it easy to fix the container to the bottom surface of the drone body and the adjacent container, and the installation and stacking efficiency is high.
[0020] This invention features a magnetic suction component. By rotating the knob in the opposite direction, the top plate moves downward until it is fully inside the third slide groove. The permanent magnet attracts the iron block, causing the iron block to move closer to the permanent magnet. This, in turn, causes the limiting rods to move closer to each other and detach from the limiting groove, making it convenient to disassemble the container. Attached Figure Description

[0036] Please see the appendix Figures 1-3 As shown, this utility model provides a drone cargo rack, including: drone body 100, cargo carrying mechanism 200, limiting rod 300, drive assembly 400 and magnetic suction assembly 500.
[0037] In a preferred embodiment, please refer to Figures 1-5 Symmetrical support legs 101 are fixedly installed at the bottom of the drone body 100, and first insertion rods 102 are fixedly installed at the four corners of the bottom surface of the drone body 100.
[0038] In a preferred embodiment, please refer to Figures 1-3The drone body 100 has a cargo-carrying mechanism 200 at its bottom. The cargo-carrying mechanism 200 consists of a container 201, a slot 202, a second insert rod 203, and a vertical groove 204. The container 201 is attached to the bottom surface of the drone body 100. The slots 202 are located at the four corners of the top surface of the container 201. The second insert rods 203 are fixedly installed at the four corners of the bottom surface of the container 201. When the container 201 is installed on the bottom surface of the drone body 100 or on the bottom surface of an adjacent container 201, the first insert rod 102 and the second insert rod 203 are aligned with the slots 202. The first insert rod 102 and the second insert rod 203 are adapted to the slots 202. The first insert rod 102 and the second insert rod 203 are slidably connected to the container 201 through the slots 202. Multiple cargo-carrying mechanisms 200 are stacked and installed at the bottom of the drone body 100, which can facilitate the classification and storage of items according to the type and volume of the items being carried.
[0039] In a preferred embodiment, please refer to Figures 1-4 The loading mechanism 200 has symmetrical limiting rods 300 and first sliding grooves adapted to the limiting rods 300. The limiting rods 300 are slidably connected to the container 201 through the first sliding grooves. The front and rear ends of the first sliding grooves are respectively connected to the slots 202. The outer sides of the first insertion rod 102 and the second insertion rod 203 are both provided with limiting grooves 301 adapted to the limiting rods 300. The limiting rods 300 are slidably connected to the first insertion rod 102 and the second insertion rod 203 through the limiting grooves 301, respectively, to hold the container... When the container 201 is installed on the bottom surface of the drone body 100 or on the bottom surface of an adjacent container 201, and both the first insertion rod 102 and the second insertion rod 203 are engaged inside the slot 202, the limiting rod 300 is aligned with the limiting groove 301. The engagement of the limiting rod 300 with the limiting groove 301 can fix the position of the container 201 relative to the drone body 100 or the adjacent container 201, thereby realizing the installation and stacking of the container 201.
[0040] In a preferred embodiment, please refer to Figures 1-5The carrying mechanism 200 has drive components 400 on both the left and right sides. Each drive component 400 consists of a knob 401, anti-slip texture 402, transmission gear 403, rack 404, connecting rod 405, top plate 406, and inclined plate 407. Symmetrical knobs 401 are rotatably connected to the left and right sides of the container 201. Anti-slip texture 402 is provided on the outer side of each knob 401. A rotating shaft is fixedly installed on the side of each knob 401 closest to the container 201. Symmetrical mounting slots are provided inside the container 201. The rotating shaft passes through the container 201 to the inside of the mounting slot and is rotatably connected to the container 201. A transmission gear 403 is fixedly installed on the side of the rotating shaft away from the knobs 401. The transmission gear 403 is located inside the mounting slot, and its left and right sides are rotatably connected to the inner wall of the mounting slot. A rack 404 meshes with the outer side of the wheel 403. The rack 404 is set inside the mounting groove. The left and right sides of the rack 404 are slidably connected to the inner wall of the mounting groove. A connecting rod 405 is fixedly set on the top surface of the rack 404. A second sliding groove adapted to the connecting rod 405 is set inside the container 201. The connecting rod 405 is slidably connected to the container 201 through the second sliding groove. The second sliding groove is connected to the mounting groove and the first sliding groove respectively. A top plate 406 is fixedly set on the top surface of the connecting rod 405. A third sliding groove adapted to the top plate 406 is set inside the container 201. The top plate 406 is slidably connected to the container 201 through the third sliding groove. The third sliding groove is connected to the first sliding groove and the second sliding groove respectively. An inclined plate 407 is fixedly set on the side of the limiting rods 300 that are close to each other. The bottom surface of the inclined plate 407 is an inclined surface.
[0041] In this embodiment, rotating the knob 401 drives the rotating shaft and the transmission gear 403 to rotate. The rotation of the transmission gear 403 drives the rack 404 to move upward. The movement of the rack 404 drives the connecting rod 405 and the top plate 406 to move upward. The top plate 406 moves and contacts the inclined surface of the inclined plate 407, causing the inclined plate 407 to move in a direction away from each other, thereby driving the limiting rods 300 to move away from each other.
[0042] In a preferred embodiment, please refer to Figures 1-4 The loading mechanism 200 is equipped with a magnetic attraction component 500, which consists of a permanent magnet 501 and an iron block 502. The permanent magnet 501 is fixedly installed on the top surface inside the first slide. The iron block 502 is fixedly installed on the side of the inclined plate 407 near the permanent magnet 501. The attraction of the permanent magnet 501 to the iron block 502 can drive the iron block 502 to move closer to the permanent magnet 501. When it is necessary to disassemble the container 201, the knob 401 is rotated in the opposite direction to move the top plate 406 downward until it is completely inside the third slide. The attraction of the permanent magnet 501 to the iron block 502 drives the iron block 502 to move closer to the permanent magnet 501, thereby driving the limiting rods 300 to move closer to each other and disengage from the limiting groove 301, so as to facilitate the downward movement of the container 201 for disassembly.
[0043] The working principle of this utility is as follows:
[0044] When in use, the device categorizes and places items into the holding box 201 according to their type and volume. The slot 202 of the holding box 201 is aligned with the first insertion rod 102 and installed onto the bottom surface of the drone body 100, causing the first insertion rod 102 to engage inside the slot 202. At this point, the limiting rod 300 is aligned with the limiting groove 301. Rotating the knobs 401 on both sides drives the rotating shaft and transmission gear 403 to rotate. The rotation of the transmission gear 403 causes the rack 404 to move upwards. The movement of the rack 404 causes the connecting rod 405 and the top plate 406 to move upwards. The top plate 406 moves and contacts the inclined surface of the inclined plate 407, causing the inclined plate 407 to move in a direction away from each other. This causes the limiting rods 300 to move away from each other until all the limiting rods 300 are engaged inside the limiting groove 301, thus fixing the position of the holding box 201 relative to the drone body 100 and achieving the installation of the holding box 201.
[0045] Align the slot 202 of another container 201 with the second insert 203 and install it onto the bottom surface of the container 201 at the bottom of the drone body 100, so that the second insert 203 engages inside the slot 202. At this time, the limiting rod 300 is just aligned with the limiting groove 301. Rotate the knobs 401 on the left and right sides to make the limiting rods 300 engage inside the limiting grooves 301. Repeating the above operation can stack multiple containers 201 at the bottom of the drone body 100, which has high installation and stacking efficiency.
[0046] When the container 201 needs to be disassembled, the knob 401 is rotated in the opposite direction to move the top plate 406 downward until it is completely inside the third slide groove. The attraction of the permanent magnet 501 to the iron block 502 causes the iron block 502 to move closer to the permanent magnet 501, thereby causing the limiting rods 300 to move closer to each other and disengage from the limiting groove 301, making it convenient to move the container 201 downward to disassemble the container 201.
[0047] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
