Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a multi-mounting section heavy-load throwing device. Background Art

[0002] As an efficient aerial delivery tool, drones are widely used. Remote material delivery using drones can be achieved through an onboard delivery device. The operator controls the rotation of the steering gear through wireless signals, and the steering gear drives the movement of the mounting pin, thereby releasing the mounted materials fixed by the mounting pin and allowing them to fall freely, completing the delivery action. As the performance of drones continues to improve, various large drones have emerged to transport materials for delivery.

[0003] The existing various types of throwers are generally suitable for small and medium-sized drones, while there are few types of large drone throwers, and slightly larger drones generally have fewer mounting points. Generally, these medium and large drones are only designed for carrying heavy objects. As a result, although these medium and large drones have a large load capacity, the number of objects they can carry is limited, and the number of objects that can be thrown in one flight is small. Almost all medium and large drones can only throw 1-2 times. This design limits the use scenarios and application scope of large drones.

[0004] This results in the usage scope of medium and large drones being unable to be fully utilized.

[0005] Based on this, the utility model designs a multi-mounting section heavy-load throwing device to solve the above problems. Utility Model Content

[0034] See also Figures 1 to 7 As shown, the utility model provides a multi-mounting section heavy-load throwing device. In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings in the specification and specific implementation methods.

[0035] In a specific embodiment of the technical solution of the utility model:

[0036] It includes a top plate 1, a mounting frame 2, a protective shell 3 and a mounting steering gear 4;

[0037] The top plate 1 is a flat plate, and a mounting frame 2 is fixedly arranged at the bottom of the top plate 1; a plurality of observation windows are provided at the top of the top plate 1, and the observation windows are through holes, and the top of each mounting compartment 21 is directly below an observation window. A docking buckle 12 is also provided at the top of the top plate 1 through the observation window, and the docking buckle 12 is a conventional device of the drone mounting mechanism, and is a structure for docking and locking with the drone tripod. The docking buckle 12 required for each drone tripod hanging device is different, and the docking buckle 12 of the device can be matched with a conventional drone tripod.

[0038] The mounting frame 2 is a frame structure, and a plurality of mutually isolated mounting chambers 21 are arranged inside the mounting frame 2, and each mounting chamber 21 is a vertical cavity with openings at both ends;

[0039] The mounting rack 2 also includes a plurality of partitions 22, each of which is a flat plate. The mounting rack 2 is formed into a frame structure by crisscrossing a plurality of vertically arranged partitions 22. The mounting rack 2 is divided into a plurality of independent mounting bins 21 by a plurality of partitions 22; the plurality of mounting bins 21 are distributed in a rectangular array, such as Figure 4 The mounting rack 2 shown is divided into six mounting compartments 21 by partitions 22 and arranged in an array.

[0040] A protective shell 3 is provided in each mounting compartment 21. The protective shell 3 protrudes outward on the vertical inner wall of the mounting compartment 21. The inner wall of the protective shell 3 and the inner wall of the mounting compartment 21 form a closed cavity. An escape opening 32 is provided on the protective shell 3. The lower side of the escape opening 32 is an outer downwardly inclined slope.

[0041] A limit rotating rod 41 is provided on the driving shaft of the mounting servo 4, and a hanging groove 43 and a mounting pin 42 are also provided on one side of the mounting servo 4. The hanging groove 43 is a U-shaped groove with an opening on one side, but it is placed horizontally so that the opening of the hanging groove 43 is also horizontal. When the mounting pin 42 is extended, it is inserted from bottom to top to the upper end of the hanging groove 43, thereby sealing the open U-shaped groove. When the mounting pin 42 is retracted, the hanging groove 43 remains open, and the upper end of the mounting pin 42 can be vertically telescopically inserted into the hanging groove 43, and the lower end of the mounting pin 42 abuts against the top of the limit rotating rod 41, and the opening of the hanging groove 43 is A spring is provided at the lower end of the opening, that is, a spring is installed outside the internal sliding channel of the mounting pin 42 and the hanging slot 43, and the spring generates a compressive elastic force between the mounting pin 42 and the hanging slot 43, so that the mounting pin 42 can generate a downward elastic force when sliding inside the hanging slot 43, so that it has a downward sliding tendency, that is, when the mounting pin 42 is not subjected to external force, the mounting pin 42 is ejected downward by the spring, and the mounting pin 42 is kept retracted downward by the spring so as not to block the opening of the hanging slot 43, thereby ensuring that the hanging slot 43 remains open when the mounting servo 4 is powered off and not working.

[0042] Two protective shells 3 are arranged in each mounting compartment 21. The two protective shells 3 are arranged in layers up and down, one protective shell 3 is arranged at the top of the inner cavity of the mounting compartment 21, and the other protective shell 3 is arranged at the middle height position of the inner cavity of the mounting compartment 21;

[0043] Each protective shell 3 and the cavity of the inner wall of the mounting compartment 21 are provided with a mounting servo 4, and the mounting slot 43 is exposed at the avoidance opening 32;

[0044] A controller 11 is also provided outside the mounting frame 2 , and each mounting servo 4 is individually connected to the controller 11 .

[0045] Compared with the existing technology, the structure of the embodiment of the utility model has the following differences:

[0046] 1. When existing medium and large drones hang materials, they generally hang one or two materials, while small materials are hung by small drones. This results in that when large drones need to be dropped multiple times, they need to take off and land multiple times due to the limitation of the number of hung materials, and small drones also need to take off and land multiple times to drop materials due to the limitation of the load of hung materials, which causes inconvenience. The present device solves this problem. When it is necessary to drop a small amount of materials multiple times, a large drone can be selected. Through the present throwing device, multiple smaller materials can be hung on one side, and the total load is much larger than that of a small drone. The number of materials mounted is also large, so that the present device can flexibly drop materials according to actual mounting needs; 2. It is also possible for large drones to hang multiple materials, but because they have a small number of mounting pins, multiple materials need to be hung on the same pin, so there are fewer delivery points. When one pin is opened, all the materials hung on it will be dropped, and multiple materials When the load is suspended on the same pin, it is easy to get stuck when the pin is extended and retracted, which may lead to a failure in the delivery. 3. In the current thrower, the pin and the slot that hold the material are both arranged horizontally. Then, when hanging the material, the material pulls the pin downward by gravity, and the pin is easily pulled and pressed into the slot, resulting in the pin being unable to retract and open the slot, resulting in a failure in the delivery of the material. The mounting pin 42 of the device is arranged vertically and is also retracted vertically, and the mounted material is also pulled downward, so that the material has a downward retraction trend on the mounting pin 42, making the retraction of the mounting pin 42 of the device smoother and more smooth, and effectively preventing the mounting pin from being locked by the material, especially under the same load condition, the device not only divides the material into multiple small materials for mounting, but also for the same material, the vertical mounting pin of the device can decompose the mounting force into lateral pressure and vertical downward force, and the probability of being stuck is much lower than that of the same weight of material being vertically hung on the horizontal pin.

[0047] When the utility model is in use, the controller 11 of the device is controlled by a remote controller, and information docking and superposition control can also be performed through the integration of the drone remote controller. The device only needs to provide structural features, and the drone remote control device belongs to conventional technology.

[0048] When mounting materials, all mounting servos 4 are driven, and the limit rotating rod 41 is rotated and lowered, so that the mounting pin 42 is retracted, and the hanging slots 43 are released, so that the hanging slots 43 are in an open state, and then the hanging ring of the materials is extended into each hanging slot 43. A material ring can be mounted in each hanging slot 43, and then the limit rotating rod 41 is controlled to rotate upward and lift up, so as to lift up the mounting pin 42 and close the hanging slots 43.

[0049] Then the drone can take off, and after arriving at the designated location, the mounting pins 42 can be remotely controlled to retract downward one by one. At this time, the materials in the hanging slot 43 fall down, and because the mounting bin 21 is vertical, the initial direction of the mounted materials is to fall vertically downward along the mounting bin 21. The material delivery direction is accurate, the throwing is convenient, the number of mounted materials is large, and the vertically retractable mounting pins 42 will not be locked in the process of the materials falling downward, and the materials will slide downward along the guide slope 31 to leave the mounting bin 21, so the throwing is smoother and the reliability is high.

[0050] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
