Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to an external payload module for UAVs. Background Technology

[0002] Currently, drones are widely used in military, agriculture, logistics, surveying and mapping, and the convenience and flexibility of their payload mounting directly affect operational efficiency. However, existing drone payload mounting methods still have the following problems:

[0003] 1. Poor mount compatibility: The interface standards between different models of drones and payloads are not uniform, which makes it difficult to adapt. Users need to customize special mount devices, which increases costs and time.

[0004] 2. Low disassembly and assembly efficiency: Traditional mechanical fixing methods (such as screws, clips, etc.) are cumbersome to operate and require tools, making it difficult to quickly change loads in the field or emergency scenarios.

[0005] 3. Insufficient stability: Some quick-release structures are susceptible to vibration and airflow during flight, which may cause the load to loosen or shift, affecting the accuracy of data acquisition or operations. Utility Model Content

[0006] The purpose of this invention is to provide an external payload module for unmanned aerial vehicles (UAVs) to solve the problems mentioned in the background section.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0008] An external payload module for unmanned aerial vehicles includes: a mounting frame body and a buffer module disposed on one side of the mounting frame body;

[0009] The bracket body includes a connecting plate and quick-release components that are respectively set on one side of the connecting plate and evenly distributed at the four corners of the connecting plate. Notches are opened on the four sides of the connecting plate, and the quick-release components are attached to the connecting plate.

[0010] Furthermore, the aforementioned components include a fixing block disposed on the connecting plate, an adjusting screw threaded through the fixing block and parallel to the connecting plate, and an arc-shaped positioning block rotatably disposed on the side of the adjusting screw away from the fixing block, with the arc surfaces of all the arc-shaped positioning blocks facing the central axis of the connecting plate.

[0011] Furthermore, the bottom centerline of the aforementioned fixing block coincides with the diagonal of the connecting plate.

[0012] Furthermore, the back side of the aforementioned arc-shaped positioning block is provided with a shaft hole, and an annular groove is provided on the outer wall of the end of the adjusting screw near the arc-shaped positioning block. A limit ring is installed in the annular groove, and the limit ring is connected to the back side of the arc-shaped positioning block by a screw.

[0013] Furthermore, the aforementioned buffer module includes a first damping plate, a damping pad, and a second damping plate connected sequentially from top to bottom. The first damping plate has support plates at its four corners on the side away from the damping pad, and all support plates are connected to the other side of the connecting plate.

[0014] Furthermore, several spring clips are arranged between the first damping plate and the damping pad, and between the second damping plate and the damping pad.

[0015] Furthermore, both the first and second damping plates mentioned above are made of aluminum alloy.

[0016] This utility model has the following beneficial effects:

[0017] This utility model's UAV payload external attachment module allows for quick clamping of integrated modules via quick-release components on the mounting bracket, and can also clamp integrated modules of different sizes without the need for external tools. The notch on the connecting plate reduces the overall weight of the mounting bracket and facilitates securing it to the UAV with external straps, resulting in a simple structure. The buffer module cushions the airflow encountered by the UAV during flight, thereby reducing the offset of the integrated module and improving the accuracy of data acquisition.

Detailed Implementation

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0023] like Figures 1 to 3As shown, this utility model provides a drone payload external attachment module, including: a mounting bracket body 1 and a buffer module 2 disposed on one side of the mounting bracket body 1; the mounting bracket body 1 can be tied to the outer wall of the drone with straps, and the mounting bracket body 1 is used for quick mounting of external integrated modules. The integrated module integrates a GPRS and / or Beidou positioning module, a 5G communication module, a drone controller pairing module, and a power supply module. The buffer module 2 can buffer the airflow and other factors encountered by the drone during flight, thereby reducing the offset of the integrated module and improving the accuracy of data acquisition by the integrated module.

[0024] The mounting bracket body 1 includes a connecting plate 11 and quick-release components 3, which are respectively disposed on one side of the connecting plate 11 and evenly distributed at the four corners of the connecting plate 11. Notches 12 are provided on the four sides of the connecting plate 11. The notches 12 can reduce the weight of the connecting plate 11 and also facilitate the binding of the connecting plate 11 to the drone with straps. A mounting slot 13 is provided on the connecting plate 11 and adjacent to the quick-release components 3. The mounting slot 13 can reduce the weight of the connecting plate 11.

[0025] Specifically, the quick-release assembly 3 includes a fixing block 31 mounted on the connecting plate 11, with the bottom centerline of the fixing block 31 coinciding with the diagonal of the connecting plate 11; an adjusting screw 32 threaded through the fixing block 31 and parallel to the connecting plate 11; and an arc-shaped positioning block 33 rotatably mounted on the side of the adjusting screw 32 away from the fixing block 31, with the arc surfaces of all the arc-shaped positioning blocks 33 facing the central axis of the connecting plate 11. In this embodiment, the side of the arc-shaped positioning block 33 closest to the adjusting screw 32 is the back side, and a shaft hole is provided on the back side of the arc-shaped positioning block 33. An annular groove is provided on the outer wall of the end of the adjusting screw 32 near the arc-shaped positioning block 33, and a limit ring 34 is installed in the annular groove. The limit ring 34 is connected to the back side of the arc-shaped positioning block 33 by a screw. Furthermore, the limiting ring 34 includes two semicircular rings, each with a protrusion on its outer side. The protrusions on the outer sides of the two semicircular rings are fixed together by screws, thereby limiting the limiting ring 34 as a whole to the annular groove of the adjusting screw 32, achieving a rotational engagement between the limiting ring 34 and the adjusting screw 32. Rotating the adjusting screw 32 adjusts its position on the fixing block 31, thereby adjusting the spacing between the four arc-shaped positioning blocks 33; and a cavity for clamping the integrated module is formed between the four arc-shaped positioning blocks 33.

[0026] The buffer module 2 includes a first damping plate 21, a damping pad 22, and a second damping plate 23 connected sequentially from top to bottom. Support plates 24 are respectively provided at the four corners of the first damping plate 21 away from the damping pad 22, and all support plates 24 are connected to the other side of the connecting plate 11. In this embodiment, both the first damping plate 21 and the second damping plate 23 are made of aluminum alloy; and the support plates 24 extend outwards in the direction away from the first damping plate 21, and are connected to the connecting plate 11 by screws. Several spring clips 25 are arranged between the first damping plate 21 and the damping pad 22, and between the second damping plate 23 and the damping pad 22, respectively, further improving the damping performance.

[0027] In use, rotating the adjusting screw 32 adjusts its position on the fixed block 31, thereby adjusting the spacing between the four arc-shaped positioning blocks 33. After placing the corresponding integrated module between the four arc-shaped positioning blocks 33, rotating the adjusting screw 32 again clamps the integrated module with all the arc-shaped positioning blocks 33. The mounting slot 13 facilitates connection to the integrated module with bolts. The groove diameter of the mounting slot 13 matches the bolt diameter, and the mounting slot 13 is located on the diagonal of the connecting plate 11, facilitating adjustment of the integrated module's position when necessary. The integrated module can then be fixed by clamping it with the quick-release assembly 3. The buffer module 2 contacts the outer wall of the drone. The buffer module 2 can buffer the airflow encountered by the drone during flight, thereby reducing the offset of the integrated module and improving the accuracy of data acquisition by the integrated module.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
