Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an ammunition multi-channel throwing device for unmanned aerial vehicles. Background Art

[0002] The application of drones has penetrated into various fields and is widely used in emergency rescue, police and fire departments to achieve long-distance transmission and precise delivery of items. Whether it is a heavy drone or a small drone, it is generally not designed with a throwing device. If you want to transport items, you need to install a throwing device on the drone.

[0003] However, existing drone throwers mostly use a separate remote control to control the external throwing equipment. When the drone flies far away, it is easy to exceed the remote control range of the independent remote control. In addition, the thrower is controlled by a servo. During transportation, the servo connecting rod is easily deformed by collision, which leads to the failure of unhooking.

[0004] Therefore, in order to ensure safe and smooth throwing, a multi-channel ammunition thrower for drones is designed in this scheme to solve the above problems. Utility Model Content

[0026] In order to more clearly illustrate the technical features of this solution, the following will elaborate on this solution through specific implementation manners.

[0027] See Figures 1 - 5 , a multi-channel ammunition throwing device for a UAV, including a UAV body 1, several arms 2 with one end connected to the UAV body 1, propellers 3 arranged at the other ends of the arms 2, and support legs 10 connected to the bottom end of the UAV body 1. A rotating mechanism 5 is arranged at the lower end of the support legs 10. The rotating mechanism 5 is connected to a rotating frame 6. A link structure 7 for positioning the ammunition box 8 is arranged on the rotating frame 6, and there are several link structures 7.

[0028] The link structure 7 includes a horizontally arranged fixing plate 71, a first link 72 with one end rotatably connected to the fixing plate 71, a second link 73 with one end hinged to the other end of the first link 72, and a sliding column 74 with one end hinged to the second link 73. A micro-motor is arranged on the fixing plate 71, and the micro-motor is connected to one end of the first link 72;

[0029] A U-shaped plate 75 with an opening facing downwards is arranged on the fixing plate 71, and the other end of the sliding column 74 horizontally penetrates through the U-shaped plate 75.

[0030] The ammunition box 8 includes a box body, ammunition arranged inside the box body, connecting seats fixed at the four corners of the ammunition box 8, and a horizontally arranged fixing column 9. One end of the fixing column 9 is vertically and fixedly connected to the connecting seat, and a through hole is arranged at the other end of the fixing column 9;
