Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV centering mechanism. Background Technology

[0002] In the field of modern drone applications, the drone landing pad centering mechanism plays a crucial role in ensuring the safe, accurate landing and stable docking of drones. With the widespread application of drones in various industries, such as logistics and distribution, surveying and mapping, and security monitoring, the performance requirements for their landing pad centering mechanisms are also increasing.

[0003] Currently, most drone landing pad centering mechanisms use a transmission system around the landing pad to open and close the mechanism. This transmission system typically includes four motors and lead screw pairs. While this structure can center the drone, the complex overall structure of the transmission system makes the landing pad prone to deformation. Furthermore, because the transmission system is located around the perimeter of the landing pad, it makes it difficult to control the overall center of gravity when the landing pad is tilted or subjected to bumps.

[0004] A utility model application with application number CN202120647985.2 discloses a drive mechanism and a UAV centering device, including a coupling, two lead screws connected to both ends of the coupling, and sliders driven by lead screw nuts on the two lead screws. One end of one of the lead screws is connected to a stepper motor. The two lead screws rotate in opposite directions. Driven by the stepper motor, the two sliders move closer to or further away from each other on the lead screws. However, in use, it still suffers from problems such as a complex overall structure, susceptibility to deformation of the landing pad, and difficulty in controlling the overall center of gravity when used under tilted or bumpy conditions.

[0039] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0040] Example:

[0041] like Figures 1 to 9 As shown, this embodiment discloses a drone centering mechanism, including a first centering component 10 and a second centering component 20. The first centering component 10 is arranged along the X-axis, and the second centering component 20 is arranged along the Y-axis, with the X-axis and Y-axis being perpendicular to each other.

[0042] The first centering component 10 includes a first mounting frame 11, a first drive structure 12, a pair of first connectors 13 and a pair of first centering rods 14. The first drive structure 12 is disposed on the first mounting frame 11. One end of the pair of first connectors 13 is disposed on the first drive structure 12. The pair of first centering rods 14 are respectively disposed on the other end of the pair of first connectors 13. The first drive structure 12 is used to drive the pair of first connectors 13 and the pair of first centering rods 14 to move closer or farther away at the same time.

[0043] The second centering component 20 includes a second mounting bracket 21, a second drive structure 22, a pair of second connectors 23, and a pair of second centering rods 24. The second drive structure 22 is mounted on the second mounting bracket 21. One end of the pair of second connectors 23 is mounted on the second drive structure 22. The pair of second centering rods 24 are respectively mounted on the other end of the pair of second connectors 23. The second drive structure 22 is used to drive the pair of second connectors 23 and the pair of second centering rods 24 to move closer or further away at the same time.

[0044] This invention employs a modular design, configuring the centering mechanism as a first centering component 10 and a second centering component 20 independently positioned along the X and Y axes, respectively. Their perpendicular orthogonal arrangement achieves bidirectional centering within a plane. This modular design reduces the number of parts, thereby lowering the overall structural complexity and effectively addressing the problem of difficulty in controlling the overall center of gravity when used under tilted or bumpy conditions. Furthermore, by incorporating a first mounting bracket 11 and a second mounting bracket 21, the first drive structure 12 and the second drive structure 22 are prevented from directly applying work to the helipad during centering, reducing direct pulling or squeezing of the helipad substrate and thus minimizing the possibility of helipad deformation. This solves the problems of complex overall structure, susceptibility to helipad deformation, and difficulty in controlling the overall center of gravity when used under tilted or bumpy conditions, present in current UAV helipad centering mechanisms.

[0045] To facilitate centering of the UAV on the X-axis, this embodiment improves upon the previous embodiment. The difference lies in that the first drive structure 12 includes a first motor 121, a first drive wheel 122, a first driven wheel 123, a first mounting base 124, a first belt 125, a pair of first sliding mounting plates 126, and a pair of first slide rails 127.

The pair of first sliders 1261 are respectively disposed on the pair of first slide rails 127 and are slidably connected to the first slide rails 127. Each pair of first sliding mounting plates 126 is provided with a first clamping member 128. The first clamping member 128 on one of the first sliding mounting plates 126 is fixedly connected to the upper end of one side of the first belt 125 by bolts. The first clamping member 128 on the other first sliding mounting plate 126 is fixedly connected to the lower end of the other side of the first belt 125 by bolts. A pair of first connecting members 13 are respectively disposed on the pair of first sliding mounting plates 126.

[0046] The first clamping member 128 includes a pair of first clamping blocks 1281, which are clamped on the first belt 125 and fixedly connected by bolts.

[0047] The first connecting member 13 includes a U-shaped block 131, a connecting rod 132, and an L-shaped locking block 133. One end of the U-shaped block 131 is fixedly connected to one side of the first sliding mounting plate 126 by bolts. The first belt 125 passes through the U-shaped block 131. One end of the connecting rod 132 is fixedly connected to the other end of the U-shaped block 131, and the other end of the connecting rod 132 is fixedly connected to the first centering rod 14 by bolts. The L-shaped locking block 133 is located on one side of the first centering rod 14. One end of the L-shaped locking block 133 is fixedly connected to the connecting rod 132 by bolts, and the other end contacts one side of the first centering rod 14.

[0048] In use, the first motor 121 drives the first drive wheel 122, which in turn drives the first belt 125 and the first driven wheel 123. The first belt 125 then drives a pair of first sliding mounting plates 126 to move closer or further away simultaneously. These sliding mounting plates 126 then drive a pair of first connecting members 13, which in turn drive a pair of first centering rods 14 to move closer or further away simultaneously, facilitating centering of the UAV along the X-axis. The belt drive system enables synchronous transmission, and compared to traditional dual-motor and dual-screw drive methods, this invention has a simpler structure.

[0049] To facilitate centering of the UAV on the Y-axis, this embodiment is an improvement upon the previous embodiment. The difference lies in that the second drive structure 22 includes a second motor 221, a second drive wheel 222, a second driven wheel 223, a second mounting base 224, a second belt 225, a pair of second sliding mounting plates 226, and a pair of second slide rails 227. The second motor 221 is mounted on one side of the second mounting bracket 21 and is fixedly connected to the second mounting bracket 21 by bolts. The second mounting base 224 is mounted on the other side of the second mounting bracket 21. The second drive wheel 222 is fixedly mounted on the output shaft of the second motor 221. The second driven wheel 223 is mounted on the second mounting base 224 and rotatably connected to the second mounting base 224. The second belt 225 is sleeved on the second drive wheel 222 and the second driven wheel 223, and is connected to the second drive wheel 222 and the second driven wheel 223 by bolts.

A pair of second sliding mounting plates 226 are fitted onto the pair of second slide rails 227. A pair of second sliders 2261 are fixedly disposed on the second sliding mounting plates 226. The pair of second sliders 2261 are respectively disposed on the pair of second slide rails 227 and are slidably connected to the second slide rails 227. A pair of second sliding mounting plates 226 are each provided with a second clamping member 228.

The bent plate 2312 is fixedly connected to the second centering rod 24 by bolts.

[0052] In use, the second motor 221 drives the second drive wheel 222, which in turn drives the second belt 225 and the second driven wheel 223. The second belt 225 then drives a pair of second sliding mounting plates 226 to move closer or further away simultaneously. These sliding mounting plates 226 then drive a pair of second connecting members 23, which in turn drive a pair of second centering rods 24 to move closer or further away simultaneously, facilitating centering of the UAV on the Y-axis. The belt drive system enables synchronous transmission, and compared to traditional dual-motor and dual-screw drive methods, this invention has a simpler structure.

[0053] This invention achieves drone centering on both the X and Y axes using only two motors. Compared to traditional centering mechanisms that require four motors and four lead screws, this invention significantly reduces the number of components in the overall structure, thereby lowering its complexity. By reducing the overall structural complexity, it effectively solves the problems of current drone landing pad centering mechanisms, such as complex structures that easily lead to landing pad deformation and difficulty in controlling the center of gravity when used under tilted or bumpy conditions.

[0054] To further facilitate the centering of the UAV, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that it also includes a landing pad platform 30. The first mounting bracket 11 and the second mounting bracket 21 are set at the bottom of the landing pad platform 30 and are fixedly connected to the bottom of the landing pad platform 30 by bolts. The second mounting bracket 21 is located above the middle of the first mounting bracket 11.

The landing pad platform 30 is provided with a first groove structure 31 that cooperates with a pair of first connecting members 13 and a second groove structure 32 that cooperates with a pair of second connecting members 23. The first connecting member 13 passes through the first groove structure 31 and is slidably connected to the first groove structure 31. The second connecting member 23 passes through the second groove structure 32 and is slidably connected to the second groove structure 32.

[0055] The first groove structure 31 includes a pair of first slide grooves 311, which are respectively located at both ends of the apron platform 30 and penetrate through the apron platform 30. The connecting rods 132 in the pair of first connectors 13 pass through the pair of first slide grooves 311 and are slidably connected to the first slide grooves 311. The second groove structure 32 includes two pairs of second slide grooves 321, which are respectively located at both ends of the apron platform 30. The pair of L-shaped connectors 231 in the pair of second connectors 23 are respectively matched with the two pairs of second slide grooves 321. The L-shaped connecting plates 2311 in the pair of L-shaped connectors 231 pass through the pair of second slide grooves 321 located at the same end of the apron platform 30 and are slidably connected to the second slide grooves 321.

[0056] By providing the first slide groove 311, the connecting rods 132 of the pair of first connectors 13 can pass through the pair of first slide grooves 311 respectively and slide within the first slide grooves 311, thereby facilitating the centering of the UAV on the X-axis. By providing the second slide groove 321, the L-shaped connecting plates 2311 of the pair of L-shaped connectors 231 can pass through the pair of second slide grooves 321 located at the same end of the landing pad platform 30 respectively and slide within the second slide grooves 321, thereby facilitating the centering of the UAV on the Y-axis.

[0057] To facilitate guiding the drone to land within a controllable range, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that a laser alignment device 33 is provided in the middle of the landing pad platform 30, which is used to emit lasers to guide the drone to land within a controllable range.

[0058] The laser alignment device 33 can be a laser emitting device that can achieve the function of this utility model in the prior art. The laser emitting device forms a crosshair or target point, which can guide the drone to land within a controllable range.

[0059] To facilitate drone charging, this embodiment is an improvement on the above embodiment. The difference is that a magnetic charging port 34 is provided on one side of the middle of the landing platform 30 for drone charging. The magnetic charging port 34 can be connected to an external power source.

[0060] The magnetic charging port 34 makes it convenient to charge drones.

[0061] Working principle of this utility model:

[0062] This invention employs a modular design, configuring the centering mechanism as a first centering component 10 and a second centering component 20 independently positioned along the X and Y axes, respectively. Their perpendicular orthogonal arrangement achieves bidirectional centering within a plane. This modular design reduces the number of parts, thereby lowering the overall structural complexity and effectively addressing the problem of difficulty in controlling the overall center of gravity during use under tilted or bumpy conditions. Furthermore, by providing a first mounting bracket 11 and a second mounting bracket 21, the first driving structure 12 and the second driving structure 22 are prevented from directly applying work to the helipad during centering, reducing direct pulling or squeezing of the helipad base plate and thus minimizing the possibility of helipad deformation.
