Description

Technical Field

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

[0002] A drone dropping device is a device specially designed to drop objects from the air. It allows drones to drop supplies or life-saving tools to specific locations during flight. Drone dropping devices are usually equipped with cameras and positioning systems to improve the accuracy of dropped objects and ensure that the materials reach their destination accurately.

[0003] At present, some relatively large drones are generally equipped with multiple throwers to improve the efficiency of material throwing. However, in actual operation, each of these throwers needs to be equipped with a separate drive source before it can be used, and all the throwers cannot be linked to each other, which will increase the space occupancy and usage cost of the equipment. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a throwing device for a drone.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A throwing device for a drone, comprising a high-definition camera fixedly mounted on the bottom outer wall of the drone body, the bottom outer wall of the drone body being fixedly connected with a mounting cover and a baffle in sequence, and a plurality of throwing mechanisms equidistantly distributed are arranged in the mounting cover;

[0007] The throwing mechanism includes a telescopic suspension shaft movably inserted on one side of the mounting cover, a connecting piece welded to the outer wall of one end of the telescopic suspension shaft, a rack fixedly connected to the side wall of the connecting piece, a guide assembly and a gear meshing with the rack;

[0008] The mounting cover is provided with a driving mechanism, and the driving mechanism includes a servo motor fixedly mounted on an outer wall of one side of the mounting cover, a worm fixedly mounted on an output shaft of the servo motor, a transmission shaft rotatably mounted in the mounting cover, and a worm wheel fixedly mounted on the transmission shaft. The driving mechanism can drive all the throwing mechanisms to work simultaneously, so that only one driving source needs to be set to realize the linkage of all the throwing mechanisms, which can effectively reduce the space occupancy and use cost of the equipment.

[0009] As a preferred technical solution of the utility model, the worm and the worm wheel are meshed with each other, and all the gears are fixedly mounted on the transmission shaft.

[0010] As a preferred technical solution of the utility model, the guide assembly includes a guide block welded to the outer wall of the bottom of the rack and a guide groove opened on the inner wall of the bottom of the mounting cover, and the outer wall of the guide block is slidably connected to the inner wall of the guide groove, which can ensure the stability of the linear motion of the rack.

[0011] As a preferred technical solution of the utility model, a photosensitive sensor and a controller are fixedly installed on the outer wall of one side of the drone body in sequence, a searchlight is fixedly installed on the bottom outer wall of the drone body, and the photosensitive sensor and the two searchlights are electrically connected to the controller. This can provide the drone operator with a clearer field of vision in a night environment, thereby improving the efficiency of the drone's throwing device at night.

[0012] The beneficial effects of the utility model are:

[0013] 1. In the process of throwing, the utility model drives the worm to rotate through the servo motor, and then the worm wheel meshing with the worm will control all the gears on the transmission shaft to rotate. At this time, each rack will retreat and drive each telescopic suspension shaft to retract so that the materials suspended on it appear to be suspended in the air. Finally, under the action of gravity, all the materials will fall to complete the automatic throwing work. In this way, only one driving source is needed to realize the linkage of all throwing mechanisms, which can effectively reduce the space occupation and use cost of the equipment;

[0014] 2. When the photosensitive sensor of the utility model senses that the flight environment is in darkness, it will transmit a signal to the controller, and the controller will control the two searchlights to start searching. This can provide a clearer field of view for the drone operator in a night environment, thereby improving the efficiency of the drone's throwing device at night. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In this embodiment, the bottom outer wall of the drone body 1 is fixedly connected with a mounting cover 2 and a baffle plate 3 in sequence, and a plurality of equally spaced throwing mechanisms are arranged in the mounting cover 2, and the throwing mechanisms include:

[0023] A telescopic suspension shaft 4 and a connecting piece 5, wherein the telescopic suspension shaft 4 is movably inserted on one side of the mounting cover 2, and the connecting piece 5 is welded to the outer wall of one end of the telescopic suspension shaft 4;

[0024] Rack 6 and gear 7, the rack 6 is fixedly connected to the side wall of the connecting member 5, and the gear 7 is meshed with the rack 6;

[0025] The guide assembly includes a guide block 8 welded to the outer wall of the bottom of the rack 6 and a guide groove 9 provided on the inner wall of the bottom of the mounting cover 2. The outer wall of the guide block 8 is slidably connected to the inner wall of the guide groove 9, which can ensure the stability of the linear motion of the rack 6.

[0026] In this embodiment, a driving mechanism is provided on the mounting cover 2, and the driving mechanism can drive all the throwing mechanisms to work simultaneously, so that only one driving source is required to realize the linkage of all the throwing mechanisms, which can effectively reduce the space occupation and use cost of the equipment. The driving mechanism includes:

[0027] A servo motor 10 and a worm 11. The servo motor 10 is fixedly mounted on an outer wall of one side of the mounting cover 2, and the worm 11 is fixedly sleeved on an output shaft of the servo motor 10.

[0029] In the specific implementation of this embodiment: first, when each telescopic suspension shaft 4 does not contact the baffle plate 3, the materials to be thrown are hung on each telescopic suspension shaft 4, and then the servo motor 10 drives the worm 11 to rotate forward, and then the worm wheel 13 meshing with the worm 11 controls all the gears 7 on the transmission shaft 12 to rotate forward, and then each rack 6 will move forward and drive each telescopic suspension shaft 4 to extend and contact the baffle plate 3, so that the materials hung on all the telescopic suspension shafts 4 can be locked;

[0030] Secondly, when throwing is required, the servo motor 10 drives the worm 11 to rotate in the opposite direction, and then the worm wheel 13 meshing with the worm 11 controls all the gears 7 on the transmission shaft 12 to rotate in the opposite direction. At this time, each rack 6 will retreat and drive each telescopic suspension shaft 4 to retract so that the materials suspended thereon appear to be suspended in the air. Finally, under the action of gravity, all the materials will fall to complete the automatic throwing work.
