Description

A drone landing platform centering device Technical Field

[0001] This utility model relates to a centering device, and more particularly to a centering device for a drone landing platform. Background Technology

[0002] With the rapid development of drone technology, its applications have expanded from the military field to the civilian market, including logistics delivery, agricultural monitoring, geographic mapping, disaster relief, and many other areas. The precision of drone operation is crucial for accomplishing these tasks. During drone missions, safe and accurate landing is one of the key aspects of ensuring continuous and efficient operation. However, in complex and ever-changing real-world environments, ensuring that drones land precisely at designated locations every time presents numerous challenges, such as changing wind directions, uneven landing sites, or obstacles. To address these issues, a device that can automatically adjust the drone's position to a center point is needed—a drone landing platform centerer. This device can automatically adjust the drone's position during landing, ensuring that the drone accurately stops at its predetermined location, thereby improving operational efficiency and safety.

[0003] Compared to existing technologies, such as the drone centering device, drone hangar, and drone system disclosed in Chinese Patent Publication No. CN221914697U, which achieve drone centering by moving the first and second push rods downwards, these push rods extend beyond the left and right sides of the landing platform when they move away from each other, and the lid also opens to the left and right sides when opened by the rotating shaft, resulting in a large space occupation. Summary of the Invention

[0004] To overcome the drawback of existing drone centering devices occupying a large space, the technical problem is to provide a drone landing platform centering device that occupies a small space.

[0005] The technical solution of this utility model is: a centering device for a UAV landing platform, comprising a centering chamber, a rotating shaft, a disc, a movable rod, a lever, a lateral centering rod, a bracket, a motor, and a longitudinal centering rod. The rotating shaft is rotatably connected to the right and front sides of the centering chamber. One end of the rotating shaft is connected to the disc. The lever is symmetrically connected to the edge of the disc. The movable rod is sleeved on the outside of the lever. The lateral centering rod is connected to the two movable rods on the front side, and the longitudinal centering rod is connected to the two movable rods on the right side. The bracket is connected to the front and right sides of the centering chamber. The motor is mounted on the bracket, and the motor is connected to the rotating shaft.

[0006] Furthermore, the longitudinal centering rod and the transverse centering rod are arranged alternately vertically.

[0007] Furthermore, it also includes guide rods, with the guide rods connected to the front and right sides of the inner wall of the centering chamber. Both longitudinal centering rods are slidably connected to the guide rod on the right side, and both transverse centering rods are slidably connected to the guide rod on the front side.

[0008] Furthermore, it also includes a bin cover, with the bin cover rotatably connected to both sides of the top of the central bin.

[0009] Furthermore, it also includes a torsion spring, a pull rope, and a winding wheel. The torsion spring is provided at the connection between the bin cover and the central bin. The winding wheel is connected to the front rotating shaft. Two pull ropes are wound on the winding wheel, and the two pull ropes are respectively connected to the bin covers on the left and right sides.

[0010] Furthermore, it also includes a sealing ring, which is connected to the side of the bin cover facing the central bin.

[0011] The beneficial effects of this invention are as follows: When waiting for the drone to land, both the longitudinal and lateral centering rods are located within the centering compartment, ensuring that the centering rods do not need to extend beyond the boundaries of the compartment during centering operations, thus reducing the need for surrounding space. Furthermore, the compartment cover automatically opens and closes through the cooperation of a torsion spring, pull rope, and winding wheel. This not only provides excellent sealing when closed but also ensures that the cover does not extend beyond the sides of the centering compartment when opened, without occupying additional side space. Therefore, this invention is particularly suitable for environments with limited space, ensuring the safe and accurate landing of the drone while significantly saving the space required for equipment operation.

Detailed Implementation

[0017] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Example 1: A centering device for a UAV landing platform, as shown in Figures 1-4, includes a centering chamber 1, a rotating shaft 4, a disc 5, a movable rod 6, a lever 7, a lateral centering rod 8, a bracket 9, a motor 10, and a longitudinal centering rod 11. The rotating shaft 4 is rotatably connected to the right and front sides of the centering chamber 1. The rotating shaft 4 passes through the side wall of the centering chamber 1. The disc 5 is fixedly connected to one end of the rotating shaft 4 facing the interior of the centering chamber 1. The lever 7 is symmetrically connected to the edge of the disc 5. The movable rod 6 is sleeved on the outer side of the lever 7. The device has an elongated hole along its length, allowing the lever 7 to move within it. The lower ends of the two movable rods 6 on the front side are connected to the transverse centering rods 8, and the lower ends of the two movable rods 6 on the right side are connected to the longitudinal centering rods 11. The longitudinal centering rods 11 and the transverse centering rods 8 are staggered vertically, with the longitudinal centering rods 11 positioned above the transverse centering rods 8. The brackets 9 are connected to the middle of the front side and the middle of the right side of the centering chamber 1. The motors 10 are mounted on the brackets 9, and the motors 10 are connected to their respective adjacent rotating shafts 4 via couplings.

[0019] As shown in Figure 3, the system also includes guide rods 12. The guide rods 12 are connected to the lower front and right sides of the inner wall of the centering chamber 1. The two guide rods 12 are staggered vertically. The two longitudinal centering rods 11 are slidably connected to the guide rod 12 on the right side, and the two transverse centering rods 8 are slidably connected to the guide rod 12 on the front side.

[0020] As shown in Figure 1, it also includes a bin cover 2, and the bin cover 2 is rotatably connected to the left and right sides of the top of the central bin 1.

[0021] As shown in Figure 4, a sealing ring 15 is also included, and the sealing ring 15 is connected to the side of the cover 2 facing the central storage compartment 1.

[0022] Initially, the cover 2 is open, and the two lateral centering rods 8 and the two longitudinal centering rods 11 are spaced apart, ready to receive the drone's landing. When the drone is ready to land, it lands at the bottom of the centering compartment 1, with its base positioned between the two lateral centering rods 8 and the two longitudinal centering rods 11. The two motors 10 are activated, and their rotation angles can be set according to the width of the drone's base, ensuring that each rotation of the motor 10 is precisely centered. The rotation of the motors 10 drives the disc 5 to rotate via the rotating shaft 4, which in turn drives the two lateral centering rods 8 and the two longitudinal centering rods 11 to move towards each other via the two levers 7, completing the centering of the drone. During this process, the guide rod 12 provides necessary sliding support for the lateral and longitudinal centering rods 11, ensuring the smoothness and accuracy of the movement. After the drone returns to center, the cover 2 is closed. The sealing ring 15 ensures a good seal between the cover 2 and the centering compartment 1. When the drone needs to take off, the two motors 10 are started to rotate in opposite directions, driving the horizontal centering rod 8 and the vertical centering rod 11 to reset, opening the cover 2, and preparing for the drone's takeoff.

[0023] Example 2: Based on Example 1, as shown in Figure 2, it further includes a torsion spring 3, a pull rope 13, and a winding wheel 14. The torsion spring 3 is provided at the connection between the compartment cover 2 and the central compartment 1. The two ends of the torsion spring 3 are respectively connected to the compartment cover 2 and the central compartment 1. The winding wheel 14 is connected to the outer side of the front end of the rotating shaft 4. Two pull ropes 13 are wound on the winding wheel 14. The two pull ropes 13 are respectively connected to the compartment covers 2 on the left and right sides.

[0024] Initially, the compartment cover 2 is open, and the torsion spring 3 is in an undeformed state. When the front motor 10 rotates to center the two transverse centering rods 8 on the drone, the rotating shaft 4 drives the winding wheel 14 to rotate clockwise. The rotation of the winding wheel 14 winds up the pull rope 13. In this embodiment, the pull rope 13 is elastic. Under the traction of the pull rope 13, the left and right compartment covers 2 gradually close until they are completely closed. The torsion spring 3 deforms. If the compartment cover 2 and the centering compartment 1 are closed, but the drone has not yet centered, the rotating shaft 4 can drive the winding wheel 14 and the disc 5 to continue rotating because the pull rope 13 is elastic. The pull rope 13 is stretched. In this way, the centering of the drone and the closing of the compartment cover 2 are carried out simultaneously. When the motor 10 is started to reverse, the winding wheel 14 releases the pull rope 13, which, under the action of the torsion spring 3, drives the two compartment covers 2 to return to the open state. The take-off of the drone and the opening of the compartment covers 2 are carried out simultaneously, realizing an efficient and stable operation process.
