[0004] The utility model provides the following technical solutions: a UAV lifting structure, including a body, the bottom of the body is fixedly connected to a lifting frame, electric telescopic rods are arranged on both sides of the bottom of the lifting frame, the surfaces of the electric telescopic rods are sleeved with bearings, the bearings are fixedly connected to the lifting frame, the electric telescopic rods are rotatably connected to the lifting frame through the bearings, the output ends of the electric telescopic rods are fixedly connected to support plates, the surface of the bottom of the lifting frame is provided with a transmission groove, the inside of the transmission groove is fixedly connected to a motor, the output end of the motor is fixedly connected to a transmission gear, the surface of the electric telescopic rods is sleeved with driven gear rings, and the driven gear rings are meshed with the transmission gear.

[0005] The beneficial effects of the utility model are as follows:

[0006] 1. The utility model controls the electric telescopic rod to extend and place the cargo on the top of the pallet through the setting of the transmission gear and the driven gear ring. Then the electric telescopic rod is controlled to retract to clamp the cargo upward and firmly. Then the drone can be controlled to fly to the unloading location, the electric telescopic rod is controlled to extend, and the transmission groove is started to rotate the transmission gear. The transmission gear drives the driven gear rings on both sides to engage, so that the driven gear ring drives the electric telescopic rod to rotate 180°. At this time, the pallet is separated from the bottom of the cargo, and the cargo slides to the ground to complete automatic unloading, which saves manpower and improves lifting efficiency.

[0007] 2. The utility model provides a clamping plate. When the pallet clamps the goods, the top of the goods contacts the clamping plate, and the spring contracts, so that the clamping plate always contacts the goods, avoiding deformation of the box body and sliding of the package caused by the pallet clamping the goods, and clamping the goods more firmly.

[0012] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0013] like Figures 1 to 4 As shown, the UAV lifting structure of this embodiment includes a body 1, a lifting frame 2 is fixedly connected to the bottom of the body 1, electric telescopic rods 3 are arranged on both sides of the bottom of the lifting frame 2, the surfaces of the electric telescopic rods 3 are sleeved with bearings 4, the bearings 4 are fixedly connected to the lifting frame 2, the electric telescopic rods 3 are rotatably connected to the lifting frame 2 through the bearings 4, the output ends of the electric telescopic rods 3 are fixedly connected to the support plates 5, the surface of the bottom of the lifting frame 2 is provided with a transmission groove 6, the inside of the transmission groove 6 is fixedly connected to the motor 7, the output end of the motor 7 is fixedly connected to the transmission gear 8, the surfaces of the electric telescopic rods 3 are sleeved with driven gear rings 9, and the driven gear rings 9 are meshed with the transmission gear 8.

[0014] refer to Figures 1 to 4 Both sides of the bottom of the hanging frame 2 are fixedly connected with fixed blocks 10, the bottom of the fixed block 10 is fixedly connected with a spring 11, and the bottom of the spring 11 is fixedly connected with a clamping plate 12.

[0015] In this embodiment, by setting the clamping plate 12, when the pallet 5 clamps the goods, the top of the goods contacts the clamping plate 12, and at the same time the spring 11 contracts, so that the clamping plate 12 always contacts the goods, avoiding the deformation of the box body and the sliding of the package caused by the pallet 5 clamping the goods, and clamping the goods more firmly.

[0016] refer to Figure 2 and Figure 3 The surface of the bottom of the splint 12 is provided with anti-skid patterns.

[0017] In this embodiment, the anti-skid pattern is provided to increase the friction between the clamping plate 12 and the goods, making it difficult for the goods to shake.
