[0035] like Figure 1-2As shown, this embodiment provides a logistics drone, including a frame 1, a fixing plate 2 installed on the frame 1, a parachute device 3 installed on the top of the fixing plate 2, a weighing device 4 installed on the bottom, an adapter plate 5 installed at the end of the weighing device 4 away from the fixing plate 2, and an automatic cargo delivery device 6 installed at the bottom of the adapter plate 5.

[0036] Specifically, the mounting plate 2 is used to mount a parachute device 3, a weighing device 4, and an automatic cargo delivery device 6 on the frame 1. The parachute device 3 is used to remotely deploy the parachute in the event of a flight malfunction of the logistics drone, reducing the risk of damage to aerial cargo and ground personnel / objects, thereby providing safety for the logistics drone. The weighing device 4 is used to detect the weight of the cargo being lifted, ensuring that the weight of the transported cargo is within the load range of the logistics drone, thus ensuring the flight safety of the logistics drone. The automatic cargo delivery device 6 is used to automatically deliver cargo to reduce labor costs and improve transportation efficiency. These three devices work together on the logistics drone to improve the operational safety and transportation efficiency of the logistics drone.

[0037] See Figure 3-4 The automatic cargo delivery device 6 includes a support frame, on which a drive mechanism, a release guide mechanism, and a clamping mechanism are mounted. One end of the release guide mechanism is connected to the drive mechanism, and the other end is connected to the clamping mechanism. The drive mechanism is connected to a flight controller and is used to drive the release guide mechanism to guide the clamping mechanism to release the cargo.

[0038] Specifically, the support bracket includes a first plate 7, a second plate 8, and a T-shaped top block 9. The second plate 8 is disposed opposite to the first plate 7. The top of the T-shaped top block 9 is fixedly connected to the bottom of the adapter plate 5, and its bottom is clamped between the first plate 7 and the second plate 8.

[0039] See Figure 5 The T-shaped top block 9 includes an integrally formed horizontal plate 10 and a vertical plate 11. The top of the vertical plate 11 is fixedly connected to the bottom of the horizontal plate 10, and the two together form a T-shaped structure. A spring seat hole is provided at the bottom of the vertical plate 11. Mounting holes are provided on both the horizontal plate 10 and the vertical plate 11.

[0040] Specifically, the adapter plate 5 is provided with a plurality of first mounting holes; the horizontal plate 10 is provided with a plurality of second mounting holes, the positions of the second mounting holes corresponding to the first mounting holes, so that the adapter plate 5 and the horizontal plate 10 can be fixedly connected by fasteners passing through the first mounting holes and the second mounting holes.

[0041] See Figure 6A hollow column 12 protrudes from the side of the first plate 7 facing the second plate 8. The end face of the hollow column 12 abuts against the surface of the second plate 8. A countersunk hole is correspondingly opened on the second plate 8. The fastener passes through the inner cavity of the hollow column 12, and its head is accommodated in the countersunk hole.

[0042] Specifically, the first plate 7 and the second plate 8 are positioned by fasteners that pass through the hollow column 12 and whose heads are accommodated in countersunk holes. The vertical plate 11 is provided with multiple third mounting holes, and the first plate 7 and the second plate 8 are provided with multiple fourth mounting holes. The positions of the fourth mounting holes are configured to correspond one-to-one with the positions of the third mounting holes. The T-shaped top block 9 is clamped and fixed between the first plate 7 and the second plate 8 by fasteners passing through the fourth mounting holes and the third mounting holes.

[0043] In this embodiment, the release guide mechanism includes a cam 13, a push rod 14 and two locking members 15. A hollow block 16 protrudes from the side of the first plate 7 facing the second plate 8, and the push rod 14 is slidably disposed in the mounting cavity of the hollow block 16.

[0044] The cam 13 is mounted on the first plate 7 and located directly below the push rod 14. When the cam 13 is in the first position, its top surface is in contact with the bottom surface of the push rod 14. When the cam 13 is in the second position, its top surface is spaced at a preset distance from the bottom surface of the push rod 14. Normally, the cam 13 is in the second position.

[0045] The top end of the push rod 14 is fitted with a return spring 17, and the other end of the return spring 17 is housed in a spring seat hole opened at the bottom of the vertical plate 11.

[0046] The push rod 14 has grooves on its two opposite side walls. One end of each of the two locking members 15 is fixedly installed on the first plate 7, and the other end is embedded in the groove.

[0047] For details, see Figure 7 The locking member 15 includes a sleeve section 18. The first plate 7 and the second plate 8 are respectively provided with two fifth mounting holes. The two sleeve sections 18 are respectively sleeved on two fasteners that pass through the four fifth mounting holes. Copper bushings 19 are respectively provided between the two sleeve sections 18 and the two fasteners.

[0048] The socket section 18 extends into a cantilever section 20. One end of each cantilever section 20 away from the two socket sections 18 is fixed in a groove opened on both sides of the push rod 14. An opening groove is opened at the bottom of each cantilever section 20.

[0049] See Figure 8The clamping mechanism includes two oppositely arranged clamps 21 and pins 22 for fixing the two clamps 21. Each clamp 21 is composed of an integrally formed clamping arm 23 and a clamping jaw 24. The ends of the two clamping arms 23 near the two clamping jaws 24 are fixed to the first plate 7 by the two pins 22. An opening for clamping goods is provided between the two clamping jaws 24. The ends of the two clamping arms 23 away from the two clamping jaws 24 are locked in the opening slots opened in the two cantilever sections 20.

[0050] In this embodiment, a tensioning mechanism is provided on each side of the clamping mechanism. The tensioning mechanism includes a support block 25 and a paddle 26. The two support blocks 25 are installed on the first plate 7. One end of the two paddles 26 is fixed on the support block 25, and the other end abuts against the head of the gripper 24.

[0051] In this embodiment, the drive mechanism includes a servo motor 27 and two servo motor pads 28. The two servo motor pads 28 are arranged vertically at intervals on the second plate 8. The servo motor 27 is fixedly installed between the two servo motor pads 28, and its output gear passes through a through hole opened on the second plate 8 and is connected to the cam 13 for transmission.

[0052] Specifically, when gripping cargo, the two grippers 24 are in a closed state, and the cargo is gripped in the opening formed by the two grippers 24. At this time, the cam 13 is in the second position, with its top surface and the bottom surface of the push rod 14 separated by a certain distance. When releasing cargo, the flight controller controls the servo motor 27 to start, and the servo motor 27 drives the cam 13 to rotate to the highest point, i.e., the first position. At this time, the top surface of the cam 13 contacts the bottom surface of the push rod 14. The cam 13 pushes the push rod 14 to move upward against the elastic force of the return spring 17. The push rod 14 drives the two locking parts 15 embedded therein to rotate upward around the two copper bushings 19 through the grooves on both sides. The two locking parts 15 drive the two gripping arms 21 to move closer to each other through the opening groove of the cantilever section 20. At the same time, the two grippers 24 open outward against the force of the two levers 26, and the cargo is released, thereby achieving the effect of automatic cargo release.

[0053] After the cargo is deployed, the flight controller shuts off the servo motor 27, and the cam 13 returns to the second position. At this time, the push rod 14 returns to its original position under the elastic force of the return spring 17, and the two locking parts 15 return to their original positions. The two grippers 24 close under the action of the two gripping arms 21.
