Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) payload technology, specifically to a UAV payload mounting adapter structure. Background Technology

[0002] With the rise of drones, many applications include spraying pesticides and hoisting and transporting goods. Many shopping malls also use drones for point-to-point delivery of takeout orders. The usual method is to fix a storage box between the bottom and the two legs of the drone, place the takeout products inside the box, and then begin point-to-point transportation. If the storage box is fixedly connected to the drone, the storage box will also tilt when the drone flies at an angle, causing the takeout products outside the box to collide with each other. If the storage box is movable, the storage box will sway in all directions when the drone flies horizontally, resulting in poor transportation efficiency. Utility Model Content

[0007] Preferably, the shaft has a threaded through hole in the upper section, and a mini electric actuator is threaded into the through hole. A vertical rod is fixedly installed at the output end of the mini electric actuator, and a small ball head is fixedly installed at the bottom of the vertical rod. The small ball head is movably installed inside the ball seat.

[0011] (III) Beneficial Effects

[0012] Compared with the prior art, this utility model provides a transfer structure for mounting UAV payloads, which has the following advantages:

[0013] 1. The adapter structure for the drone payload mounting: When the drone is flying horizontally, a mini electric actuator moves the vertical rod downwards, pushing the limiting plate down through the through hole. The pressure plate then presses against the inner wall of the large ball seat. The pressure plate has a raised ring on its surface, which increases friction by pressing against the inner wall of the large ball seat, thus ensuring a lock between the large ball head and the large ball seat and preventing the storage box from shaking or swaying in the wind. This process achieves a rigid connection between the storage box and the drone. Conversely, when the drone is flying at an angle, the mini electric actuator moves the vertical rod upwards, the pressure plate no longer presses against the inner wall of the large ball seat, and the large ball head and the large ball seat unlock. The storage box is then lowered by gravity, ensuring it remains horizontal. This process achieves a flexible connection between the storage box and the drone.

[0014] 2. The adapter structure for mounting the drone payload allows for adjustment of the distance between the upper and lower supports by loosening the self-locking nut; simultaneously, pushing the lower support to rotate around the shaft adjusts the horizontal angle of the storage box.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 A transfer structure for mounting a drone payload includes an upper bracket 1, which is detachably installed to the bottom shell of the drone by bolts. A transfer component 2 is provided at the bottom of the upper bracket 1, and a lower bracket 3 is provided at the bottom of the transfer component 2. A storage box 4 is fixedly installed at the bottom of the lower bracket 3, and a box door 5 is hinged to the side of the storage box 4.

[0023] Please see Figure 3-4 The adapter assembly 2 includes a shaft 21, with two symmetrically arranged washers 22 fitted on the outer side of the shaft 21. Two symmetrically arranged self-locking nuts 23 are threaded to the outer side of the shaft 21. The shaft 21 is inserted into the upper bracket 1 and can be detachably installed with the upper bracket 1 through the washers 22 and the self-locking nuts 23. The distance between the upper bracket 1 and the lower bracket 3 can be adjusted by loosening the self-locking nuts 23.

[0024] See Figure 3-4 A large ball head 24 is fixedly installed at the bottom of the shaft 21. The large ball head 24 is movably installed inside the large ball seat 25. The large ball seat 25 is fixedly installed on the surface of the lower bracket 3. At the same time, it pushes the lower bracket 3 to rotate around the shaft 21, which can adjust the horizontal angle of the storage box 4.

[0025] Please see Figure 4-5The shaft 21 has a threaded through hole 26 at the top, through which a mini electric actuator 27 is threadedly connected. The mini electric actuator 27 is connected to the UAV control system. A vertical rod 28 is fixedly installed at the output end of the mini electric actuator 27, and a small ball head 29 is fixedly installed at the bottom of the vertical rod 28. The small ball head 29 is movably installed inside the small ball seat 210. The mini electric actuator 27 can push the small ball seat 210 to move up or down.

[0026] Please see Figure 4-5 A limiting plate 211 is fixedly installed at the bottom of the ball seat 210. A slider 212 is fixedly installed on the outer side of the limiting plate 211. The inner wall of the through hole 26 is provided with a groove 213 corresponding to the slider 212. The limiting plate 211 slides up and down in the through hole 26 through the slider 212 and the groove 213. The slider 212 can both restrict the limiting plate 211 from rotating and ensure that the limiting plate 211 can move up and down.

[0027] Please see Figure 4-5 An extension rod 214 is fixedly installed at the bottom of the limiting plate 211, and a pressure plate 215 is fixedly installed at the bottom of the extension rod 214. The pressure plate 215 is curved and combines with the large ball head 24 to form a complete arc surface. A convex ring 216 is fixedly installed at the bottom of the pressure plate 215 to increase the contact friction and improve locking. The extension rod 214 is inserted into the inside of the limiting ring 217, and the limiting ring 217 is threaded to the bottom opening of the through hole 26.

[0028] Working principle: When the drone is flying horizontally, the mini electric push rod 27 moves the vertical rod 28 downward. The vertical rod 28 pushes the limiting plate 211 down through the through hole 26, and then the pressure plate 215 presses against the inner wall of the large ball seat 25. The surface of the pressure plate 215 is provided with a convex ring 216. The convex ring 216 presses against the inner wall of the large ball seat 25, which can increase the friction and thus ensure that the large ball head 24 and the large ball seat 25 are locked together, preventing the storage box 4 from shaking or swaying in the wind. This process realizes the rigid connection between the storage box 4 and the drone.

[0029] Conversely, when the drone is flying at an angle, the mini electric actuator 27 moves the vertical rod 28 upward, the pressure plate 215 is no longer pressed against the inner wall of the large ball seat 25, the large ball head 24 is unlocked from the large ball seat 25, and the storage box 4 is lowered by gravity, ensuring that the storage box 4 is in a horizontal position. This process achieves a flexible connection between the storage box 4 and the drone. At the same time, when the storage box 4 is lowered, the mini electric actuator 27 can also push the pressure plate 215 to press against the large ball seat 25, ensuring that the storage box 4 will not shake due to the drone's violent tilt.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
