[0019] 1. The present invention provides an automatic helipad for unmanned aerial vehicles. When the unmanned aerial vehicle is landing, the wind shield provides a wind protection function for the unmanned aerial vehicle. In outdoor environments, wind is an important factor affecting the landing of unmanned aerial vehicles. The wind shield can effectively block and weaken the airflow, creating a relatively stable landing environment for the unmanned aerial vehicle. The wind shield can make the airflow flowing through the landing area become smooth, reduce the generation of turbulence, and reduce the lateral thrust and lift changes received by the unmanned aerial vehicle during the landing process, thereby making it easier to maintain a balanced and stable posture. At the same time, the wind shield can be used as a visual reference to help the unmanned aerial vehicle better locate the landing position. The unmanned aerial vehicle can adjust its own landing path according to the position of the wind shield, so that it can be more accurately aligned with the center of the helipad or the designated landing area, thereby improving the landing accuracy.

[0020] 2. The present invention provides an automatic helipad for UAV. When the UAV contacts the parking disc, the parking disc drives the wind shield to descend under the action of the gravity of the UAV, thereby effectively preventing the UAV from colliding with the wind shield during landing, which is beneficial to protecting the safety of the UAV and extending the service life of the UAV.

[0021] 3. The present invention provides an automatic drone landing pad. The main body of the drone landing pad adopts a folding design, which saves space and is easy to carry. The legs of the high-torque electric telescopic push rod are designed as separate adjustable mechanisms. By adjusting each leg, the platform is in a horizontal state, which is convenient for the take-off and landing of the drone. The high-torque electric telescopic push rod can accurately control the telescopic length of the push rod through a motor drive. It has a high-precision transmission mechanism inside, such as a ball screw or a planetary gear system. These mechanisms can convert the rotational motion of the motor into the linear motion of the push rod, and can accurately control the displacement of the push rod, which is beneficial to ensuring the stability of the drone landing pad. At the same time, a detachable structure is adopted, which is convenient for disassembly of the device and is beneficial to improving the portability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The wind shield 203 forms a rotating structure with the expansion parking plate 201 through the rotating shaft 202 with a torsion spring, and the expansion parking plate 201 and the UAV landing pad body 1 form a sliding structure, the outer diameter of the fixed ball 204 is the same as the inner diameter of the engaging groove 205, and the fixed ball 204 and the engaging groove 205 form a rotating structure, the parking disc 208 and the two end rotating shaft connecting plates 207 form a rotating structure, and the two end rotating shaft connecting plates 207 and the arc ring 206 form a rotating structure, and the arc ring 206 and the adjacent arc ring 206 form a rotating structure. The connection relationship between them is a nested connection, and the arc ring 206 and the adjacent arc ring 206 form a sliding structure, the second rotating plate 212 forms a rotating structure with the first rotating plate 210 through the rotating plate shaft 211, and the first rotating plate 210 forms a rotating structure with the expansion shutdown plate 201 through the self-tightening shaft 209, the second rotating plate 212 forms a magnetic adsorption structure with the wind shield plate 203 by connecting the magnet 213, and a pair of second rotating plates 212 are symmetrically arranged about the vertical center axis of the wind shield plate 203.

[0035] The expansion parking plate 201 is slid out of the main body 1 of the drone landing pad. Under the action of the rotating shaft 202 with a torsion spring, the wind shield plate 203 rotates forty-five degrees around the rotating shaft 202 with a torsion spring. Then, the first rotating plate 210 is rotated around the self-tightening rotating shaft 209 until the first rotating plate 210 and the expansion parking plate 201 are on the same horizontal line. Then, the second rotating plate 212 is rotated around the rotating plate rotating shaft 211. Under the action of the connecting magnet 213, the second rotating plate 212 is adsorbed with the wind shield plate 203, and the second rotating plate 212 follows the wind shield. The wind shield 203 is active. When the drone is landing, the wind shield 203 provides wind protection for the drone. In outdoor environments, wind is an important factor affecting the landing of the drone. The wind shield 203 can effectively block and weaken the airflow, creating a relatively stable landing environment for the drone. The wind shield 203 can make the airflow flowing through the landing area smooth, reduce the generation of turbulence, and reduce the lateral thrust and lift changes received by the drone during the landing process, so that it is easier to maintain a balanced and stable posture. At the same time, the wind shield 203 can be used as a visual reference to help the drone better The landing position can be located accurately. The UAV can adjust its landing path according to the position of the windshield to make it more accurately align with the center of the apron or the designated landing area, thereby improving the landing accuracy. Then, when the UAV contacts the parking disc 208, the downward pressure generated by the UAV causes the parking disc 208 to move downward. During the movement of the parking disc 208, the parking disc 208 rotates around the rotating shaft connecting plates 207 at both ends, and the arc ring 206 rotates around the rotating shaft connecting plates 207 at both ends. The adjacent arc rings 206 begin to extend. At this time, the arc ring 206 begins to When the drone descends, the arc ring 206 rotates around the fixed ball 204 through the engaging groove 205. Under the action of the arc ring 206, the wind shield 203 rotates around the rotating shaft 202 with the torsion spring, so that the wind shield 203 slowly contacts the extended stop plate 201. When the drone stops completely, the wind shield 203 and the extended stop plate 201 are on the same horizontal line. At the same time, the second rotating plate 212 moves with the wind shield 203, which effectively avoids the collision between the drone and the wind shield 203 during the landing process, which is beneficial to protecting the safety of the drone and extending the service life of the drone.

The drone apron body 1 adopts a folding design, which saves space and is easy to carry. Then put the drone apron body 1 on the positioning slot, connect the head and tail of the platform by hand-tightening the nut, and then install the fixed connector 5 with the platform connector 4.
