Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically a suspended UAV cargo-carrying device. Background Technology

[0002] A suspended drone cargo carrier is a type of mounting equipment used on drones to enable the suspended transport of goods. Through the flight control of the drone, the cargo carrier is transported above the goods, and the goods are grabbed using hooks or clamps. Then, the drone carries the goods to the target location.

[0003] To facilitate the transport of goods of different sizes and heights, existing suspended drone cargo-carrying devices typically employ a bidirectional adjustable screw to adjust and raise an L-shaped clamp to secure the goods. For example, Chinese utility model patent with announcement number CN220363464U discloses a suspended drone cargo-carrying device.

[0004] However, in actual use, it has been found that the aforementioned suspended drone cargo-carrying device can only clamp and fix the cargo on both sides, making it difficult to limit the other two sides of the cargo. This can cause the cargo to move to the unclamped side, resulting in poor safety. Utility Model Content

[0005] The purpose of this utility model is to provide a suspended unmanned aerial vehicle (UAV) cargo-carrying device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a suspended unmanned aerial vehicle (UAV) cargo-carrying device, comprising a mounting frame, a bidirectional drive assembly, a lifting clamping plate assembly, and a side clamping plate assembly.

[0007] Two bidirectional drive components are symmetrically arranged below the mounting frame. Each bidirectional drive component has two symmetrically arranged lifting clamping plate components below it. Each lifting clamping plate component has a lateral clamping plate component near its bottom. The drone body is mounted above the mounting frame. The bidirectional drive components drive the two lifting clamping plate components below to clamp the cargo. Each lifting clamping plate component is height-adjustable, and the lateral clamping plate components adjust with the height of the lifting clamping plate components, clamping the other two sides of the cargo.

[0008] In a preferred embodiment of this invention, the bidirectional drive assembly includes a track, a bidirectional lead screw, lead screw sliders, and a first knob. The track is fixed below the mounting frame, and the bidirectional lead screw is rotatably connected inside the track. One end of the bidirectional lead screw passes through the track and connects to the first knob. Two lead screw sliders are symmetrically threaded onto the bidirectional lead screw, and a lifting clamping plate assembly is provided below each lead screw slider. By rotating the first knob, the bidirectional lead screw can be rotated, driving the two lead screw sliders to move closer or further apart. When they move closer, the lifting clamping plate assembly clamps the goods.

[0009] In a preferred embodiment of this invention, the lead screw and slider are fitted against the inner wall of the track, and the lead screw and slider are slidably connected within the track. This serves to restrict the movement of the lead screw and slider, thereby improving the stability of their movement.

[0010] In a preferred embodiment of this invention, the lifting clamp assembly includes a movable cylinder, a movable block, a second lead screw, a second knob, and a first clamping plate. The movable cylinder is fixed below the lead screw slider, the movable block is slidably connected inside the movable cylinder, the second lead screw is fixed below the movable block, the second knob is rotatably connected below the movable cylinder, the second lead screw passes through the second knob, and there is a threaded connection between the second lead screw and the second knob. The first clamping plate is fixed to the end of the second lead screw. By rotating the second knob, the second knob drives the second lead screw to move up and down, thereby causing the first clamping plate to rise and fall, changing the clamping height.

[0011] In a preferred embodiment of this invention, the movable cylinder has a rectangular interior, the movable block is a square slider that mates with the movable cylinder, and the first clamping plate is L-shaped. The square movable cylinder and movable block prevent the lead screw from rotating with the second knob, and the L-shaped first clamping plate can support the goods.

[0012] In a preferred embodiment of this invention, the lateral clamping plate assembly includes a connecting plate, a third lead screw, a second clamping plate, a positioning rod, and a third knob. The connecting plate is fixed to the side of the first clamping plate. The third lead screw and the positioning rod both penetrate the connecting plate, and the third lead screw is threadedly connected to the connecting plate. One end of the third lead screw is rotatably connected to the second clamping plate, and the other end of the third lead screw is fixed to the third knob. One end of the positioning rod is fixed to the second clamping plate. By rotating the third knob, the third lead screw is rotated, causing the third lead screw to move on the connecting plate. The third lead screw then moves the second clamping plate, clamping the other two sides of the goods.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The bidirectional drive assembly of this invention synchronously drives the two clamping plates via bidirectional lead screws, ensuring uniform lateral clamping force. The L-shaped first clamping plate supports the bottom of the goods, preventing them from falling. The lateral clamping plate assembly further reinforces the structure longitudinally, forming a stable structure of "clamping on all four sides and supporting the bottom," suitable for goods of different shapes and sizes. The lifting clamping plate assembly can be independently adjusted in height, allowing for flexible adaptation to different cargo heights and enhancing the versatility of the device.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a suspended unmanned aerial vehicle (UAV) cargo carrier device, including a mounting frame 1, a bidirectional drive assembly 2, a lifting clamping plate assembly 3, and a side clamping plate assembly 4.

[0024] Two bidirectional drive components 2 are provided, symmetrically arranged below the mounting frame 1. Each bidirectional drive component 2 has two symmetrically arranged lifting clamping plate components 3 below it. Each lifting clamping plate component 3 has a lateral clamping plate component 4 near its bottom. The drone body 5 is mounted above the mounting frame 1. The bidirectional drive components 2 drive the two lifting clamping plate components 3 below to clamp the cargo. Each lifting clamping plate component 3 is height-adjustable, and the lateral clamping plate components 4 adjust with the height of the lifting clamping plate components 3, clamping the other two sides of the cargo.

[0025] Furthermore, the bidirectional drive assembly 2 includes a track 201, a bidirectional lead screw 202, lead screw sliders 203, and a first knob 204. The track 201 is fixed below the mounting frame 1. The bidirectional lead screw 202 is rotatably connected inside the track 201. One end of the bidirectional lead screw 202 passes through the track 201 and is connected to the first knob 204. Two lead screw sliders 203 are symmetrically threaded onto the bidirectional lead screw 202. A lifting clamping plate assembly 3 is provided below each lead screw slider 203. By rotating the first knob 204, the bidirectional lead screw 202 can be rotated, driving the two lead screw sliders 203 to move closer or further apart. When they move closer, the lifting clamping plate assembly 3 clamps the goods.

[0026] Furthermore, the lead screw slider 203 is fitted against the inner wall of the track 201, and the lead screw slider 203 is slidably connected within the track 201. This serves to restrict the movement of the lead screw slider 203 and improve its stability.

[0027] Furthermore, the lifting clamping plate assembly 3 includes a movable cylinder 301, a movable block 302, a second lead screw 303, a second knob 304, and a first clamping plate 305. The movable cylinder 301 is fixed below the lead screw slider 203, the movable block 302 is slidably connected inside the movable cylinder 301, the second lead screw 303 is fixed below the movable block 302, the second knob 304 is rotatably connected below the movable cylinder 301, the second lead screw 303 passes through the second knob 304, and there is a threaded connection between the second lead screw 303 and the second knob 304. The first clamping plate 305 is fixed to the end of the second lead screw 303. By rotating the second knob 304, the second knob 304 drives the second lead screw 303 to move up and down, thereby causing the first clamping plate 305 to rise and fall, changing the clamping height.

[0028] Furthermore, the interior of the movable cylinder 301 is a rectangular space, the movable block 302 is a square slider that cooperates with the movable cylinder 301, and the first clamping plate 305 is L-shaped. The square movable cylinder 301 and movable block 302 can prevent the lead screw from rotating with the second knob 304, and the L-shaped first clamping plate 305 can support the goods.

[0029] Furthermore, the lateral clamping plate assembly 4 includes a connecting plate 401, a third lead screw 402, a second clamping plate 403, a positioning rod 404, and a third knob 405. The connecting plate 401 is fixed to the side of the first clamping plate 305. The third lead screw 402 and the positioning rod 404 both pass through the connecting plate 401, and the third lead screw 402 is threadedly connected to the connecting plate 401. One end of the third lead screw 402 is rotatably connected to the second clamping plate 403, and the other end of the third lead screw 402 is fixed to the third knob 405. One end of the positioning rod 404 is fixed to the second clamping plate 403. By rotating the third knob 405, the third lead screw 402 is rotated, causing the third lead screw 402 to move on the connecting plate 401. The third lead screw 402 then moves the second clamping plate 403, clamping the other two sides of the goods.

[0030] In summary, when this device is in use, rotating the first knob 204 causes the bidirectional lead screw 202 to rotate within the track 201. Since the bidirectional lead screw 202 is symmetrically threadedly connected to the two lead screw sliders 203, and the lead screw sliders 203 are restricted by the track 201 to only slide, the two lead screw sliders 203 will move closer or further away from each other as the bidirectional lead screw 202 rotates, thereby driving the lifting clamping plate assembly 3 below to move synchronously, achieving initial clamping or release of the goods laterally (on both sides).

[0031] When the second knob 304 is turned, because the second knob 304 is threadedly connected to the second lead screw 303, and the movable block 302 (square) cannot rotate within the movable cylinder 301 (rectangular space), the second lead screw 303 will move up and down with the rotation of the second knob 304, thereby driving the L-shaped first clamp 305 at the end to rise and fall, adapting to goods of different heights, and supporting the bottom of the goods through the L-shaped structure.

[0032] Once the lifting clamp assembly 3 is adjusted to the appropriate height, the third knob 405 is turned to drive the third lead screw 402 to rotate and move on the connecting plate 401. Since the positioning rod 404 restricts the movement direction of the second clamp 403, the third lead screw 402 will push the second clamp 403 closer to the goods and cooperate with the second clamp 403 on the other side to complete the clamping from the other two sides (longitudinal) of the goods, and finally achieve all-round fixation of the goods.

[0033] It is worth noting that the entire device is controlled by a master control button. Since the device matched with the control button is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
