Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a landing and take-off apron device for unmanned aerial vehicles. Background Art

[0002] In recent years, with the rapid development of unmanned aerial vehicle (UAV) technology, its application areas have become increasingly broad, covering agricultural monitoring, topographic mapping, express delivery, emergency rescue and many other aspects. The widespread use of UAVs has put forward higher requirements on the functionality and efficiency of their take-off and landing facilities. Traditional UAV take-off and landing aprons are mostly fixed designs and are usually used under flat ground conditions. In complex or changing environments, such as mountainous areas, urban ruins or temporary rescue sites, the ground is often uneven, which poses a challenge to the safe take-off and landing of UAVs.

[0003] However, most drone landing pads are fixed at a fixed height or need to be adjusted manually, which not only increases the complexity of operation but also limits the ability to deploy quickly. The main problems with manually adjusting the landing pad include: cumbersome operation, long adjustment time, high skill requirements for operators, and it is difficult to accurately control the ideal height. Utility Model Content

[0004] In response to the above problems, the utility model provides an unmanned aerial vehicle landing and take-off apron device, which effectively solves the problems that manual adjustment of the apron is cumbersome, takes a long time to adjust, requires high skills of the operator, and is difficult to accurately control to the ideal height.

[0005] The utility model adopts the following technical solutions:

[0006] A landing and take-off apron device for an unmanned aerial vehicle comprises a circular plate, three connecting plates are evenly arranged on the edge of the circular plate, a micro motor is installed at the bottom of the connecting plate, a rotating end of the micro motor passes through the connecting plate and is connected to a driving gear, a sleeve is arranged at the top of the connecting plate on one side of the driving gear, a driven gear is connected to the top of the sleeve through a bearing, the driven gear is meshed and connected to the driving gear, threaded holes are arranged in the driven gear, the sleeve and the connecting plate, the inner ring of the bearing is connected to the sleeve, the outer ring of the bearing is connected to the driven gear, a screw is threadedly connected in the threaded hole, the top and bottom of the screw are connected to a limiting cap, and a circular foot is arranged at the bottom of the limiting cap at the bottom of the screw.

[0007] Furthermore, a battery is installed at the center of the bottom of the circular plate, a controller is installed at the bottom of the circular plate, and the battery is electrically connected to the controller and the micro motor.

[0008] Furthermore, three positioning holes are formed on the circular foot, and the bottom of the circular plate is connected to a positioning pin storage tube, in which a positioning pin for inserting into the positioning hole is arranged.

[0009] Furthermore, a rubber pad is arranged on the top of the circular plate.

[0010] The advantages of the utility model are: the rotation of the driving gear is controlled by the built-in micro motor, so that the driving gear is meshed with the driven gear, and then the height is automatically adjusted through the screw. The height can be accurately adjusted to adapt to uneven ground without manual operation, which greatly improves the convenience and efficiency of use. By combining the positioning pin with the positioning hole on the foot, it can ensure that the landing pad remains stable after being adjusted to the appropriate height, avoiding shaking or tilting caused by uneven ground, and improving the safety of drone take-off and landing. The electric adjustment mechanism is much faster than manual adjustment, and can quickly adjust to the appropriate height when the drone approaches, providing immediate support, especially in emergency situations, and can more effectively support the rapid take-off and landing of the drone. The electric mechanism has less wear than the manual mechanism. Therefore, the maintenance requirements of the device are lower and the service life is longer, which can reduce long-term maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

The sleeve 17 is connected to the inner ring of the bearing 5, and the driven gear 6 is connected to the outer ring of the bearing 5. Therefore, the screw 8 can move up and down to adjust the height to adapt to the uneven terrain. Once the height of the apron is adjusted to the ideal state, the operator can take out the positioning pin 15 from the positioning pin storage tube 14 and insert it into the positioning hole 13 on the circular foot 10, thereby locking the height of the apron and ensuring its stability.
