Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of unmanned aerial vehicles (UAVs), in particular to a UAV throwing mechanism. Background Art
[0002] Due to the different functions and uses of drones, drones are often used as carriers to mount different devices such as gimbals, speakers, and lights to expand the functions of drones. Installing a thrower on the drone can achieve rapid transportation and supply of materials in places such as firefighting, disaster relief, and logistics. Many existing drone throwers rely on the weight of the heavy object to achieve throwing, and may fail to throw lighter objects. In addition, if the drone loses power, it is impossible to manually unlock the heavy object already mounted on the thrower, and power needs to be turned on to unlock it. The whole process is cumbersome and affects the user experience.
[0003] For example, a drone casting mechanism (Announcement No.: CN219096968U) includes a mounting plate with symmetrical grooves on the mounting plate, a movable block slidably connected in the groove, a gear 1 rotatably connected to the center of the upper end surface of the mounting plate, a rack 1 provided on both the front and rear sides of the gear 1, the rack 1 meshing with the gear 1, the separated end of the rack 1 connected to the movable block, the upper end surface of the gear 1 and the gear 2 concentric therewith, an electric push rod connected to the mounting plate above, the piston rod of the electric push rod provided with a rack 2, the rack 2 meshing with the gear 2, L-shaped connecting pieces are provided at the front and rear ends of the middle section of the upper end surface of the mounting plate, connecting rods are symmetrically provided on the movable block, the lower end of the connecting rods is exposed from the lower end surface of the movable block, a support plate is provided at the lower end of the connecting rod, one end of the support plate is opposite, and a limit piece is provided on the upper end surface of the support plate. The advantage of this utility model is that it can well fix and cast objects of different sizes.
[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that when the above device is used, the piston rod of the electric push rod is extended to drive the movable block to move away from each other in the slot, thereby causing the support plate and the limit plate to move away from each other. When the support plate moves out of the two ends of the parachuting object, the parachuting object is thrown down, and parachuting objects of different sizes can be thrown down. This device has the problem of failure to throw lighter objects, and when the drone is powered off, it is impossible to manually unlock the heavy object that has been mounted on the thrower, and it needs to be powered on to unlock. Therefore, we need to propose a drone throwing mechanism. Utility Model Content
