Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a grabbing mechanism for unmanned aerial vehicles. Background Art

[0002] A drone is an unmanned aerial vehicle controlled by a radio remote control device or its own program control device. With the rapid development of the drone industry, more and more drones are being used in agriculture, forestry, electricity, surveying and mapping, telemetry and other industries. At present, the drone logistics and transportation industry is receiving more and more attention.

[0003] When existing drones are used for logistics transportation, the logistics boxes containing goods are generally fixed to the bottom of the drone body by manual labor. The logistics boxes cannot be automatically and flexibly grasped, which affects the efficiency of logistics transportation. Therefore, we have introduced a new grasping mechanism for drones. Utility Model Content

[0004] The main purpose of the utility model is to provide a grabbing mechanism for a drone, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A gripping mechanism for a drone comprises a drone body, wherein the left front portion and the left rear portion of the lower end and the right front portion and the right rear portion of the lower end of the drone body are fixedly connected to a fixing column, the lower ends of the two longitudinal fixing columns are commonly fixedly connected to a connecting seat, the lower front portions and the lower rear portions of the two connecting seats are provided with connecting grooves, the inner front portions and the inner rear portions of the two connecting seats are provided with sliding grooves, the middle portions of the lower ends of the two connecting seats are fixedly connected to a connecting plate, the front and rear ends of the two connecting plates are fixedly installed with cylinders, the output ends of the four cylinders are fixedly connected to a connecting block, the upper ends of the four connecting blocks are fixedly connected to a connecting column, the upper ends of the four connecting columns are fixedly connected to a sliding block, the lower ends of the four connecting blocks are fixedly connected to a clamping rod, the opposite surfaces of the two longitudinal clamping rods are fixedly connected to a clamping pad, and the lower ends of the four clamping rods are fixedly connected to a hooking block.

[0007] Preferably, the four connecting grooves are respectively connected to the four sliding grooves.

[0008] Preferably, the four connecting posts are respectively inserted and connected with the four connecting grooves.

[0009] Preferably, the four sliding blocks are slidably connected to four sliding grooves respectively.

[0010] Preferably, the two longitudinal clamping rods are symmetrically distributed front to back.

[0011] Preferably, the upper ends of the four hook blocks are all provided with inclined surfaces, and the inclined surfaces of the four hook blocks are all provided with anti-slip stripes.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. When the drone is located above the logistics box, the two longitudinal cylinders are started, and the two longitudinal cylinders respectively drive the two longitudinal clamping rods to move relative to each other, so that the two hook blocks extend into the bottom of the logistics box. The upper ends of the two hook blocks are provided with inclined surfaces, which are convenient for being placed in the bottom of the logistics box, so that the clamping pads on the two clamping rods fit closely with the front and rear sides of the logistics box. The front and rear sides of the logistics box are clamped and limited by the two longitudinal clamping rods, which is convenient for automatic grabbing of the logistics box. It is more flexible to use and can improve the efficiency of logistics transportation;

[0014] 2. After the logistics box is grabbed, the bottom of the logistics box is supported and limited by the hook block, and anti-slip stripes are set on the inclined surface of the hook block to increase the friction between the bottom of the logistics box and prevent the logistics box from slipping. At the same time, when the clamping rod clamps the logistics box, the clamping pad can improve the protection of the logistics box and prevent the logistics box from being scratched or damaged.
