[0024] A disaster relief delivery device for an unmanned aerial vehicle, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a storage box 10 for storing materials, and the storage box 10 forms a hollow box structure; a bottom plate 11 for support is arranged at the bottom of the storage box 10, and a top plate 12 for installation with a drone is arranged on the top of the storage box 10. The storage box 10 is detachably connected to the top plate 12 through a locking structure. The locking structure includes a connecting block 20, a plug rod 21 and an anti-slip groove 22. The connecting block 20 is fixedly connected to the storage box 10 and plugged into the top plate 12. Two anti-slip grooves 22 are symmetrically provided on the side wall of the connecting block 20. Two plug rods 21 are arranged on the wall surface of the top plate 12. The two plug rods 21 can be inserted into the two anti-slip grooves 22 respectively. A driving structure is also arranged on the wall surface of the top plate 12 to push the plug rod 21 to slide. In the scheme, by inserting the two plug rods 21 into the corresponding anti-slip grooves 22, the connection block 20 is limited and locked, which can ensure the load-bearing capacity of the connection block 20. Secondly, when the UAV turns, the connection block 20 is plugged into the top plate 12 and limited by the parallel extending plug rods 21, which can have a higher shear resistance effect. Compared with the prior art that uses electromagnet adsorption to fix the storage box 10, this scheme can carry a heavier weight of materials and has stronger stability after connection. At the same time, compared with the fixation method of electromagnet adsorption, this scheme only needs power supply when delivering materials. Compared with the electromagnet energized adsorption method, it can reduce energy consumption, improve the overall endurance of the UAV, and thus increase the number of times materials are delivered.

[0025] like Figure 5 and Figure 6As shown, the locking structure also includes a socket 23. The wall surface of the top plate 12 is provided with the socket 23. The connecting block 20 is inserted into the socket 23. The socket 23 is adapted to the connecting block 20. By inserting the connecting block 20 into the socket 23, the connecting block 20 forms a circular plate structure. The lower end surface of the connecting block 20 is fixedly connected to the top of the storage box 10. Two anti-slip grooves 22 are symmetrically provided on the circumferential surface of the connecting block 20. The connecting block 20 with a circular structure can be more easily inserted into the socket 23, so as to facilitate the connection between the storage box 10 and the top plate 12. At the same time, the circular connecting block 20 can have a better shear resistance effect to resist the shear concentration caused by the roll during steering.

[0026] like Figure 3 As shown, a cross bar is provided between the two plug rods 21, and both ends of the cross bar are fixedly connected to the two plug rods 21 respectively. The two plug rods 21 are connected by the cross bar so that the two plug rods 21 can maintain synchronous movement, thereby achieving synchronous release of the connection block 20.

[0027] like Figure 3 As shown, the top and bottom surfaces of the insertion rod 21 are both provided with axial holes, and a roller is rotatably connected in the axial hole. The roller is tangent to the wall surface of the insertion rod 21. By setting the roller, the insertion rod 21 can slide more smoothly in the anti-slip groove 22, reducing the resistance of the insertion rod 21 during displacement, and facilitating the insertion rod 21 to slide out of the anti-slip groove 22.

[0028] like Figure 2 and Figure 3 As shown, the driving structure includes a motor, gears and an installation box, the installation box is fixedly connected to the top plate 12, the motor is fixedly installed inside the installation box, the gears are fixedly connected to the output shaft of the motor, the side wall surface of the insertion rod 21 is provided with teeth, the gears are meshed with the teeth, and the motor drives the gear to move one of the insertion rods 21 to slide, and the insertion rod 21 drives the other insertion rod 21 to slide synchronously, thereby achieving the release of the lock on the connecting block 20 and realizing the release of the storage box 10.

[0029] like Figure 6 As shown, the locking structure also includes a sliding channel 24. Two sliding channels 24 are opened on the front wall of the top plate 12. The two insertion rods 21 slide in the corresponding sliding channels 24. The sliding channels 24 are connected with the insertion holes 23. The sliding channels 24 form a rectangular groove structure. The insertion rod 21 and the sliding channels 24 cooperate with each other. By setting the sliding channels 24 and limiting the insertion rod 21 by using the sliding channels 24, the insertion rod 21 maintains linear displacement without deviation and shaking, and the locking effect of the insertion rod 21 on the connecting block 20 is better and more stable.

[0030] It should be noted that a connecting rod is provided on the top surface of the top plate 12, and the connecting rod is locked and fixed to the drone by bolts, thereby realizing the installation and fixation of the top plate 12. A shock absorber is installed on the top surface of the bottom plate 11. The specific model and specification of the shock absorber are not restricted too much here. The shock absorber output shaft is fixedly connected to the bottom of 10.

[0031] The working principle of the utility model is as follows: a connecting rod is provided on the top surface of the top plate 12, and the connecting rod is locked and fixed to the drone by bolts. Materials are placed in the storage box 10, and the connecting block 20 is inserted into the socket 23. The motor drives the gear to move the plug rod 21 to slide, and the plug rod 21 drives the cross bar and another plug rod 21 to move synchronously. The plug rod 21 slides in the limit channel 24, and the plug rod 21 gradually moves into the anti-slip groove 22 to lock the connecting block 20. After the drone reaches the specified position, it is started by controlling the motor, and the gear is used to move the plug rod 21, and the plug rod 21 slips out of the anti-slip groove 22, so that the storage box 20 and the connecting block 20 fall to realize the delivery of materials. The motor needs to be connected to the control panel of the drone, and the start and stop of the motor can be controlled by remote control. The type and model of the motor are not restricted too much here.

[0032] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
