Description

Technical Field

[0001] The invention relates to the technical field of unmanned aerial vehicle pods, and in particular to a low-cost simple unmanned aerial vehicle with a pod structure. Background Art

[0002] With the maturity of drone technology, the application scope of drones is becoming wider and wider. For example, in order to solve the problem of the last mile of logistics transportation, people have proposed to use drones to transport goods. The way to use drones to transport goods is usually to load the goods into the cargo hold of the drone. At present, the society's demand for easy-to-disassemble logistics drone pods basically meets people's needs, but there are still some problems. Drone pods are a mission payload installed on drones, mainly used for drones to transport and deliver materials. Traditional drone pods have complex structural designs, a large number of parts, high processing difficulty, and high subsequent assembly difficulty; when used, cargo loading is complex and inefficient, which increases the cost of use. Because the traditional drone pod structure contains too many parts and the overall structure is very complex, the pod is easily damaged after the delivery mission is completed. Due to the high cost of the pod itself, a lot of repairs and secondary use are required, which further increases the cost of use.

[0003] A low-cost simple drone pod structure provided by the publication number "CN114229010A" includes a pod, a lug is arranged on the upper part of the pod, and the surface of the pod is wrapped by a waterproof layer; an opening is arranged at the rear of the pod, and the waterproof layer forms a plurality of folding structures at the opening; the pod includes an upper pod and a lower pod, the upper pod and the lower pod are arranged opposite to each other and connected and fixed by a fastening structure, a storage space is formed between the upper pod and the lower pod, a buffer is arranged at the front end of the storage space, and a main support beam is arranged at the top of the storage space, and the two ends of the main support beam are respectively provided with a front support member and a rear support member. The present invention can increase the amount of cargo carried by the drone; after being dropped, the impact on the pod body is minimized by the flexible buffer member to avoid damage to the pod and improve the protection of the internal cargo; the pod has high processing and assembly efficiency, reduces the use cost, and makes drone cargo transportation more economical.

[0004] However, the above device still has the following problems during implementation:

[0005] There is still room for improvement in the pods used by drones. While meeting the load-bearing capacity of the pod, the existing device may transport liquids when in use. However, when the pod loaded with liquid is in operation, the drone is easily affected by wind in the air, which can cause the liquid to sway back and forth in the pod, and may even cause the liquid to move to one side, resulting in uneven weight on both ends of the pod, causing the drone to lose stability and easily cause the drone to fall. Therefore, a more reasonable technical solution should be proposed to optimize and improve drones with pods and solve the technical problems existing in the prior art. Summary of the invention

Example

[0042] Based on the first embodiment, this embodiment describes the installation mechanism 300 in the first embodiment.

[0043] The mounting mechanism 300 includes a second rotating seat 301, which is fixedly mounted on the bottom of the first slider 104, a fixed seat 302 is rotatably mounted inside the second rotating seat 301, a support plate 303 is fixedly mounted on the bottom of the fixed seat 302, a first mounting seat 304 and a second mounting seat 305 are fixedly mounted on the bottom of the support plate 303, a sliding groove is provided inside the first mounting seat 304, fourth grooves are provided on both sides of the sliding groove, a third guide rod 306 is fixedly mounted on the inner wall of the fourth groove, a third slider 307 is sleeved on the outer wall of the third guide rod 306, a third spring 308 is fixedly mounted on one side of the third slider 307, an end of the third spring 308 away from the third slider 307 is fixedly mounted on the inner wall of the fourth groove, and a connecting rod 306 is fixedly mounted on one side of the third slider 307 The connecting plate 309 has a first plug rod 310 installed inside it, a handle is fixedly installed at one end of the first plug rod 310, and the end of the first plug rod 310 away from the handle is tapered. A mounting frame 311 is sleeved on the outer wall of the first plug rod 310, and a slot matching the first plug rod 310 is opened inside the mounting frame 311. The pod body 113 is fixedly installed at the bottom of the mounting frame 311. The user can pull the handle. In the process of pulling the handle, the connecting plate 309 can be pulled, and the first plug rod 310 can be pulled at the same time. During the movement of the first plug rod 310, the third slider 307 can be driven to slide on the third guide rod 306, and the third slider 307 can compress the third spring 308 during the movement.

[0044] The second mounting seat 305 is also provided with a sliding groove, and both sides of the sliding groove in the second mounting seat 305 are provided with fifth grooves, the inner wall of the fifth groove is fixedly installed with a fourth guide rod 312, the outer wall of the fourth guide rod 312 is sleeved with a fourth sliding block 313, a fourth spring 314 is fixedly installed on one side of the fourth sliding block 313, and the fourth spring 314 is fixedly installed on the inner wall of the fifth groove at one end away from the fourth sliding block 313, and a second plug rod 315 is fixedly installed on one side of the fourth sliding block 313, and one end of the second plug rod 315 passes through the bottom of the second mounting seat 305 and is also fixedly connected to a handle, and a slot is also provided inside the second mounting seat 305, and the slot is matched with the tapered end of the first plug rod 310, and a second limiting slot is provided at the bottom of the tapered end of the first plug rod 310, and the second limiting slot is matched with the top of the second plug rod 315. When the first plug rod 310 moves to a certain position, the mounting bracket 311 at the top of the pod body 113 is then mounted on the first The third slider 307 drives the connecting plate 309 and the first rod 310 to move toward the mounting bracket 311, and then passes through the slot into the slot of the second mounting seat 305, and then pulls the handle at the bottom of the second rod 315, and then pulls the second rod 315. During the movement, the second rod 315 can control the fourth slider 313 to slide on the fourth guide rod 312 and squeeze the fourth spring 314. When the second limiting groove at the bottom of the first rod 310 moves above the second rod 315, the second rod 315 is released, and under the action of the fourth spring 314, the second rod 315 enters the second limiting groove to lock the first rod 310, so that the pod body 113 can be installed conveniently to prevent the pod body 113 from falling.

[0045] Working principle: When the device is in use, the user can pull the handle. In the process of pulling the handle, the connecting plate 309 can be pulled, and the first plug rod 310 can be pulled at the same time. The first plug rod 310 can drive the third slider 307 to slide on the third guide rod 306 during the movement. The third slider 307 can compress the third spring 308 during the movement. When the first plug rod 310 moves to a certain position, the mounting bracket 311 on the top of the pod body 113 is then installed between the first mounting seat 304 and the second mounting seat 305. Then the handle is released. Under the action of the third spring 308, the third slider 307 will drive the connecting plate 309 and the first plug rod 310 to move toward the mounting bracket 311.

[0046] After that, the second rod 315 is pushed and the fourth slider 313 is pushed on the fourth guide rod 312, and the fourth spring 314 is squeezed. When the second limiting groove at the bottom of the first rod 310 moves to the top of the second rod 315, the second rod 315 is released. Under the action of the fourth spring 314, the second rod 315 enters the second limiting groove to lock the first rod 310. Then, the limiting groove cooperates with the dovetail card plate 201 to facilitate the installation and removal of the counterweight block 202, thereby matching the weight of the liquid in the pod body 113, and improving the stability of the device to a certain extent, so as to prevent the drone body 101 from falling due to uneven weight when driving the pod body 113 in flight.

[0047] Then, the drone body 101 is started. When the drone body 101 is flying in the air with the pod body 113, once it encounters airflow, the liquid in the pod body 113 will slosh, thereby causing the drone body 101 and the pod body 113 to tilt. During the tilting process, the pod body 113 will control the first slider 104 to slide on the first guide rod 103, and the first slider 104 will squeeze one first spring 105 and stretch the other first spring 105 at the same time. During the sliding process, the first slider 104 can drive the first rotating seat 106 to move, and during the movement of the first rotating seat 106, it will drive the connecting rod 104 to move. One end of the rod 107 rotates in the first rotating seat 106, and at the same time controls the connecting rod 107 to slide on the outer wall of the limiting column 108 through the first limiting groove. During the sliding process of the connecting rod 107 on the outer wall of the limiting column 108, one end of the extension rod 112 will resist the limiting column 108, thereby controlling the extension rod 112 to move in the first limiting groove. During the movement of the extension rod 112, it can drive the second slider 110 to slide on the second guide rod 109. During the sliding process of the second slider 110, it can squeeze the second spring 111, thereby controlling the counterweight block 202 to match the weight of the liquid in the pod body 113 under the action of the lever.

[0048] It should be noted that the drone body 101 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
