Description

Technical Field

[0001] This utility model relates to the field of landing guidance devices, specifically to a visual guidance device for precise landing of unmanned aerial vehicles (UAVs). Background Technology

[0002] A drone vision-guided precision landing system is an integrated system that uses computer vision technology to provide drones with precise location information through real-time analysis of environmental images or video data, enabling safe and accurate landings. This system typically combines hardware devices (such as cameras and sensors) with software algorithms, simulating human visual perception mechanisms to allow drones to autonomously identify landing targets and achieve high-precision landings in complex environments.

[0003] Traditional visual-guided precision landing devices for drones typically have a single-plane landing platform with a fixed height, making them unsuitable for drones with varying landing gear heights. Furthermore, when using tags to guide drones, most of these tags are single tags or QR codes, which cannot be adjusted to suit different situations and drones.

[0004] Therefore, it is necessary to invent a visually guided precision landing device for drones to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a visual guidance device for precise landing of drones. When the camera in a different drone identifies and positions the labels on the first and second label plates, pulling the handle rotates the drum, allowing the four sets of first label plates on the outside of the drum to switch, thereby meeting the visual guidance needs of different drones. This enables the drone to accurately visually identify the position of the guide base and the connecting seat at high altitude, thus achieving precise landing. This solves the problem mentioned in the background art that traditional visual guidance devices for precise landing of drones typically have a single planar structure with a fixed height, making them unsuitable for drones with varying landing gear heights. Furthermore, when using labels to guide drones, most of these are single labels or QR codes, which cannot be adjusted according to different situations and drones.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a UAV visual guidance precision landing guidance device, including a guidance base for supporting the UAV visual guidance precision landing guidance device;

[0007] A handle is located on the outside of the guide base. A transmission rod is fixedly connected to the inside of the handle. A rotating cylinder is fixedly connected to the front end of the transmission rod. A first spring is sleeved on the outside of the transmission rod. A first label plate is fixedly connected to the outside of the rotating cylinder. A limit block is provided on the other side of the rotating cylinder. A limit groove matching the limit block is opened inside the guide base.

[0008] A connector is fixedly installed on the front side of the guide base, and a second label plate is threaded onto the connector.

[0009] Preferably, a support base is fixedly connected to the outer side of the guide base, and a laser radar is fixedly installed above the support base.

[0010] Preferably, the transmission rod passes through the interior of the guide base, and the rotating drum is rotatably connected to the guide base.

[0011] Preferably, the other side surface of the rotating drum is provided with a mounting groove, and a second spring is fixedly connected inside the mounting groove. The rear side of the limiting block is fixedly connected to the front end of the second spring.

[0012] Preferably, the surfaces of the guide base and the connecting seat are covered with rubber pads, and the interior of the guide base and the connecting seat is provided with a display groove, with the first label plate and the second label plate located inside the display groove.

[0013] Preferably, each of the connecting seats has a threaded groove inside, and the outer perimeter of the second label plate is threaded with bolts, with the front end of the bolts penetrating inside the threaded groove.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] This invention, through the design of a guide base, handle, rotating drum, first label plate, connecting seat, and second label plate, not only creates platforms at different heights but also allows for the use of different labels for different drones. The characteristics and colors of these labels can be adjusted and switched, improving the accuracy of visual guidance and positioning. When the first and second label plates are identified and positioned by the cameras in different drones, pulling the handle rotates the drum, switching the four sets of first label plates on the outside of the drum. This satisfies the visual guidance needs of different drones, enabling them to accurately visually identify the positions of the guide base and connecting seat at high altitudes for precise landing.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-5 The device shown is a visual-guided precision landing guide for a drone, including a guide base 1 for supporting the visual-guided precision landing guide for the drone.

[0026] Handle 4 is located on the outside of guide base 1. A transmission rod 5 is fixedly connected to the inside of handle 4. A rotating cylinder 6 is fixedly connected to the front end of transmission rod 5. A first spring 7 is sleeved on the outside of transmission rod 5. A first label plate 8 is fixedly connected to the outside of rotating cylinder 6. A limit block 11 is provided on the other side of rotating cylinder 6. A limit groove matching the limit block 11 is opened inside guide base 1.

[0027] The connector 12 is fixedly installed on the front side of the guide base 1. The connector 12 is threaded with a second label plate 15. When the first label plate 8 and the label plate 15 are identified and located by the camera in different drones, the handle 4 is pulled to drive the rotating drum 6 to rotate, so that the four sets of first label plates 8 on the outside of the rotating drum 6 can be switched, thereby meeting the visual guidance of different drones. This allows the drone to accurately visually identify the position of the guide base 1 and the connector 12 in the high air, and thus land accurately.

[0028] like Figure 2 , Figure 3 and Figure 4As shown, a support base 2 is fixedly connected to the outside of the guide base 1, and a lidar 3 is fixedly installed on the top of the support base 2. The lidar 3 can measure the distance and relative position between the drone and the guide base 1, providing the drone with more accurate positioning information.

[0029] like Figure 2 and Figure 3 As shown, the transmission rod 5 passes through the inside of the guide base 1, and the rotating cylinder 6 is rotatably connected to the guide base 1. By rotating the handle 4, the transmission rod 5 and the rotating cylinder 6 are driven to rotate. By rotating the rotating cylinder 6 inside the guide base 1, different first label plates 8 can be switched to meet the label requirements of different drones.

[0030] like Figure 3 and Figure 4 As shown, mounting grooves 9 are provided on the other side surface of the rotating cylinder 6. A second spring 10 is fixedly connected inside the mounting groove 9. The rear side of the limiting block 11 is fixedly connected to the front end of the second spring 10. By pulling the handle 4, the transmission rod 5 and the rotating cylinder 6 are moved to the rear, so that the limiting block 11 on the other side of the rotating cylinder 6 is disengaged halfway from the limiting groove inside the guide base 1, so that the half-circle head of the front end of the limiting block 11 remains in the limiting groove. Then, by rotating the rotating cylinder 6, the half-circle head of the front end of the limiting block 11 and the second spring 10 on the rear side are squeezed, so that the limiting block 11 is disengaged from the limiting groove inside the guide base 1, so that the rotating cylinder 6 can rotate. After rotating and adjusting to the required position, the handle 4 is released, and the first spring 7 outside the transmission rod 5 rebounds and pushes the rotating cylinder 6 and the multiple limiting blocks 11 in front to insert into the limiting groove inside the guide base 1 to limit and fix the rotating cylinder 6.

[0031] like Figure 1 and Figure 5 As shown, rubber pads 13 are attached to the surfaces of the guide base 1 and the connecting base 12. Display slots are provided inside the guide base 1 and the connecting base 12, and the first label plate 8 and the second label plate 15 are located inside the display slots. The rubber pads 13 can cushion and support the drone landing, thereby improving anti-slip properties.

[0032] like Figure 5 As shown, threaded grooves 14 are provided inside the connector 12. Bolts 16 are threaded around the outer perimeter of the second label plate 15, and the front end of the bolts 16 passes through the threaded grooves 14. The second label plate 15 can be removed from the connector 12 by means of the bolts 16, and different second label plates 15 can be replaced for identifying drones.

[0033] The working principle of this utility model is as follows: First, adjust the first label plate 8 and the second label plate 15 according to different drones. First, pull the handle 4 on the outside of the guide base 1 to move the transmission rod 5 and the rotating drum 6 to the rear, while simultaneously compressing the first spring 7 on the rear side. At this time, the limiting block 11 on the other side of the rotating drum 6 disengages halfway from the limiting groove inside the guide base 1, leaving the semi-circular head of the limiting block 11 in the limiting groove. Then, by rotating the rotating drum 6, the semi-circular head of the limiting block 11 and the second spring 10 on the rear side are compressed, causing the limiting block 11 to disengage from the limiting groove inside the guide base 1, allowing the rotating drum 6 to rotate. After rotating and adjusting to the desired position of the first label plate 8, release the handle 4. The first spring 7 outside the transmission rod 5 will then push the rotating drum 6 to the front of multiple labels. The limiting block 11 is inserted into the limiting groove inside the guide base 1 to limit and fix the rotating cylinder 6. Next, the second label plate 15 inside the connecting seat 12 is removed and replaced by bolt 16. When the drone needs to land, the camera inside the drone visually identifies the different patterns of the first label plate 8 and the second label plate 15 in the sky. After identification, the drone will fly to the guide base 1 and the connecting seat 12 according to the position identified by the camera. After getting close, the lidar 3 can measure the distance and relative position between the drone and the guide base 1, providing the drone with more accurate positioning information. Then the drone accurately lands on the guide base 1 and the connecting seat 12. In this way, the use of the drone visual guidance precision landing guidance device is completed.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
