Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV hoisting and suspension mechanism with an automatic unhooking function. Background Technology

[0002] The drone lifting suspension mechanism, also known as the automatic unhooking device, is a device used to suspend goods under a drone to achieve lifting and transportation functions. It can provide a reliable connection point for the goods, enabling the drone to carry and transport them. It has a wide range of applications in logistics and express delivery.

[0003] When using an automatic unhooking device to lift and suspend goods, it is necessary to open the two hooks of the device, place the lifting rope connected to the goods between the two hooks, and then close the two hooks. However, when the drone is lifting and transporting goods, the lifting rope is prone to shifting and swaying on the two hooks, which will cause the goods to sway more violently under the rope. This may affect the balance of the drone and make it difficult for the drone to operate normally. Utility Model Content

[0004] This utility model proposes a drone hoisting suspension mechanism with an automatic unhooking function to solve the problem that when drones are hoisting and transporting goods, the hoisting rope is prone to shifting and swaying on the two hanging rings, which will cause the goods to sway more violently under the hoisting rope. This may affect the balance of the drone and make it difficult for the drone to operate normally.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drone hoisting and suspension mechanism with automatic unhooking function, including a unhooking device body, a connecting ring rotatably mounted on the top of the unhooking device body, the connecting ring being installed at the bottom of the drone body, an auxiliary groove being provided at one end of the unhooking device body, hooks being provided on both sides of the inner wall of the auxiliary groove, an auxiliary device being provided between the auxiliary groove and the hooks, the auxiliary device using a pressure plate to squeeze and limit the hoisting rope and the hooks, and the pressure plate being provided.

[0006] The effect achieved by the above components is as follows: by adjusting the pressure plate, the pressure plate moves toward the hanging rope on the hook until the pressure plate completely clamps the hanging rope and the two hooks. This helps to prevent the hanging rope from shifting and swaying on the hook, which would cause the goods to sway more violently under the hanging rope. This reduces the impact on the balance of the drone and facilitates the normal operation of the drone.

[0007] Preferably, the auxiliary device includes a pressure plate disposed inside the auxiliary groove. The pressure plate is disposed on one side of the two hooks. A spring is symmetrically fixedly installed on one side of the pressure plate. An extension plate is fixedly installed on one end of the spring. The two extension plates are symmetrically installed on both sides of the unhooking device body.

[0008] The effect achieved by the above components is as follows: by setting up a pressure plate, when the spring is not subjected to other external forces, the spring will squeeze the pressure plate, causing the pressure plate to move downward until one side of the pressure plate completely clamps the lifting rope and the two hooks. The pressure plate can fix the lifting rope and the two hooks, which helps to prevent the lifting rope from easily shifting and swaying on the two hanging rings.

[0009] Preferably, the spring has a round rod inside, one end of which is fixedly mounted on one side of the pressure plate, and the outer surface of which is slidably mounted on the inner wall of the extension plate.

[0010] The effect achieved by the above components is that by setting the round rod, the round rod can limit and guide the spring, which helps to prevent the spring from deforming.

[0011] Preferably, one end of the round rod passes through the inner wall of the extension plate and is fixedly installed with an L-shaped plate, wherein a bolt is threaded into the inner wall of the L-shaped plate.

[0012] The effect achieved by the above components is as follows: by rotating the bolt, one end of the bolt passes through the inner wall of the L-shaped plate until one end of the bolt abuts against one side of the release device body, the bolt can fix the L-shaped plate and the release device body, which helps to prevent the pressure plate from easily loosening the fixation of the lifting rope.

[0013] Preferably, limit strips are symmetrically installed on both sides of the unhooking device body, and the L-shaped plate is slidably installed on one side of the two limit strips.

[0014] The effect achieved by the above components is that by setting two limit bars, the L-shaped plate can be limited, making the L-shaped plate more stable during movement.

[0015] Preferably, rubber strips are bonded to the inner walls of both sides of the unhooking device body, and the bolts are located on one side of the rubber strips.

[0016] The effect achieved by the above components is that by setting a rubber strip, it can replace one end of the release device body and the bolt to abut, and increase the friction between the bolt and the release device body, making the bolt more securely fixed to the L-shaped plate.

[0017] Preferably, a silicone plate is fixedly installed on the side of the pressure plate near the two hooks.

[0018] The effect achieved by the above-mentioned components is that by setting up a silicone plate, one side of the pressure plate can be in contact with the suspension rope, which helps to make the pressure plate more secure in fixing the suspension rope.

[0019] Preferably, a first silicone sleeve and a second silicone sleeve are fixedly installed at one end of each of the two hooks, and the first silicone sleeve and the second silicone sleeve abut and engage with each other.

[0020] The effect achieved by the above-mentioned components is that by setting the first silicone sleeve and the second silicone sleeve, the connection between the two hooks and the suspension rope can be replaced, thereby providing a certain degree of protection for the suspension rope.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by adjusting the pressure plate, the pressure plate moves toward the hanging rope on the hook until the pressure plate completely clamps the hanging rope and the two hooks. This helps to prevent the hanging rope from shifting and swaying on the hook, which would cause the goods to sway more violently under the hanging rope. This reduces the impact on the balance of the drone and facilitates the normal operation of the drone. Attached Figure Description

[0028] Example 1, referring to Figures 1-3As shown, this embodiment discloses a drone hoisting suspension mechanism with an automatic unhooking function, including a unhooking device body 3. A connecting ring 2 is rotatably mounted on the top of the unhooking device body 3, and the connecting ring 2 is installed on the bottom of the drone body 1. An auxiliary groove 4 is provided at one end of the unhooking device body 3, and hooks 5 are provided on both sides of the inner wall of the auxiliary groove 4. An auxiliary device 6 is provided between the auxiliary groove 4 and the hooks 5. The auxiliary device 6 uses a pressure plate 61 to squeeze and limit the hoisting rope and the hooks 5. By setting the pressure plate 61 and adjusting the pressure plate 61, the pressure plate 61 is directed towards the hooks 5. The hanging rope is moved until the pressure plate 61 completely clamps the hanging rope and the two hooks 5. This helps to prevent the hanging rope from shifting and swaying on the hooks 5, which would cause the cargo to sway more violently under the hanging rope, thereby reducing the impact on the balance of the drone and facilitating the normal operation of the drone. The automatic unhooking device can be a PJK30-P dual-hook DJI M30 drone automatic unhooking device. The two hooks 5 can be controlled remotely to slide into the interior of the unhooking device body, thereby achieving the function of automatic unhooking.

[0029] Reference Figure 2 and Figure 3 As shown, the auxiliary device 6 includes a pressure plate 61, which is located inside the auxiliary groove 4 and on one side of the two hooks 5. A spring 62 is symmetrically fixedly installed on one side of the pressure plate 61, and an extension plate 63 is fixedly installed on one end of the spring 62. The two extension plates 63 are symmetrically installed on both sides of the unhooking device body 3. By setting the pressure plate 61, when the spring 62 is not subjected to other external forces, the spring 62 will squeeze the pressure plate 61, causing the pressure plate 61 to move downward until one side of the pressure plate 61 completely clamps the lifting rope and the two hooks 5. The pressure plate 61 can fix the lifting rope and the two hooks 5, which helps to prevent the lifting rope from easily shifting and shaking on the two hanging rings. A round rod 64 is set inside the spring 62. One end of the round rod 64 is fixedly installed on one side of the pressure plate 61, and the outer surface of the round rod 64 is slidably installed on the inner wall of the extension plate 63. By setting the round rod 64, the round rod 64 can limit and guide the spring 62, which helps to prevent the spring 62 from deforming.

[0030] Reference Figure 2 and Figure 3As shown, one end of the round rod 64 passes through the inner wall of the extension plate 63 and is fixedly installed with an L-shaped plate 65. A bolt 66 is threaded into the inner wall of the L-shaped plate 65. By rotating the bolt 66, one end of the bolt 66 passes through the inner wall of the L-shaped plate 65 until one end of the bolt 66 abuts against one side of the release device body 3. The bolt 66 can then fix the L-shaped plate 65 and the release device body 3, which helps to prevent the pressure plate 61 from easily loosening its fixation on the lifting rope. Limiting strips 67 are symmetrically installed on both sides of the release device body 3. The L-shaped plate 65 is slidably installed on one side of the two limiting strips 67. By setting the two limiting strips 67, the L-shaped plate 65 can be limited, making the L-shaped plate 65 more stable during movement.

[0031] Reference Figure 2 and Figure 3 As shown, rubber strips 68 are bonded to the inner walls of both sides of the release device body 3. Bolts 66 are set on one side of the rubber strips 68. By setting the rubber strips 68, one end of the release device body 3 and the bolt 66 can be abutted, and the friction between the bolt 66 and the release device body 3 can be increased, making the bolt 66 more firmly fixed to the L-shaped plate 65. A silicone plate 69 is fixedly installed on the side of the pressure plate 61 near the two hooks 5. By setting the silicone plate 69, one side of the pressure plate 61 can be abutted against the lifting rope, which helps to make the pressure plate 61 more firmly fixed to the lifting rope.

[0032] Reference Figure 3 and Figure 4 As shown, a first silicone sleeve 610 and a second silicone sleeve 611 are fixedly installed on one end of each of the two hooks 5. The first silicone sleeve 610 and the second silicone sleeve 611 abut and engage with each other. By setting the first silicone sleeve 610 and the second silicone sleeve 611, the connection point of the two hooks 5 and the suspension rope can be replaced, thereby providing a certain degree of protection for the suspension rope.

[0033] Working principle: Pushing the pressure plate 61 away from the two hooks 5 causes the pressure plate 61 to compress the spring 62, causing the spring 62 to deform. Then, the lifting rope connected to the cargo is placed between the two hooks and the pressure plate 61. The two hooks are then closed, causing the first silicone sleeve 610 and the second silicone sleeve 611 to abut and engage with each other. Removing the force applied to the pressure plate 61 causes the spring 62 to reset and move the pressure plate 61 toward the lifting rope. The pressure plate 61 causes the L-shaped plate 65 connected to the round rod 64 to move between the two limit strips 67. At this time, the pressure plate 61 can be pushed to assist until the silicone plate 69 on one side of the pressure plate 61 is fully in contact with the lifting rope. Rotating the bolt 66 causes one end of the bolt 66 to abut with the rubber strip 68 on one side of the release device body 3. The bolt 66 can then fix the L-shaped plate 65 and the release device body 3, which helps to prevent the pressure plate 61 from easily loosening due to compression of the lifting rope.
