Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) airport structure technology, and in particular to a charging device for UAV airports. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices. Currently, the ground support system for UAVs is still relatively backward, mainly consisting of runways / aprons and radio remote control equipment. Runways are suitable for UAVs that take off and land on taxiways, while aprons are suitable for UAVs that take off and land vertically.

[0003] In the prior art, Chinese utility model patent CN218662399U discloses "a drone airport, which uses shock-absorbing pads and shock-absorbing springs to absorb shock. When the drone lands on the shock-absorbing pads, the shock-absorbing pads slide on the base plate, and the elasticity of the shock-absorbing springs absorbs the strong vibrations suffered by the drone during landing. Then, it is fixed by a clamping mechanism, which effectively solves the problem of strong vibrations when the drone lands." However, this type of drone airport still has the following drawbacks:

[0004] (1) In actual use, the drone cannot be quickly charged after landing and stopping, which reduces the battery life of the next drone flight mission and cannot guarantee that it will be fully charged every time it takes off.

[0005] (2) In actual use, the drone cannot be fixed and its position cannot be straightened, making it inconvenient to charge the drone.

[0006] Chinese invention patent CN111776237B discloses a drone airport and a drone system. The drone can be electrically connected to a second electrode of a first charging device below the drone landing pad, thereby charging the drone. The system also has a lifting device that can vertically adjust the height of the first electrode.

[0007] However, the aforementioned drone airport cannot assist the drone in aligning itself, requiring precise control of the drone for correction, which complicates the operation. Furthermore, the drone is only supported and fixed by the first insulating part of the first charging device to achieve limited positioning, resulting in poor stability. Utility Model Content

[0008] The purpose of this invention is to overcome the shortcomings of existing technologies, such as the inability of drone airports to assist drones in orienting themselves, requiring precise control of the drone for orienting, which leads to complex operation, and the poor stability of relying solely on support and fixation for positioning. This invention provides a charging device for drone airports.

[0009] In a first aspect, this utility model provides a charging device for unmanned aerial vehicles (UAVs) at airports, including...

[0010] A helipad frame, wherein the helipad frame is provided with a landing plate, the landing plate being used to support the unmanned aerial vehicle (UAV);

[0011] A lifting charging assembly is provided with a charging interface on the top of the lifting charging assembly. The height of the charging interface can be adjusted by the lifting charging assembly. The stop plate is provided with a through hole adapted to the charging interface.

[0012] A clamping and fixing assembly includes at least one pair of clamping rods, each pair of clamping rods being disposed on one opposite side of the through hole, and each pair of clamping rods being capable of clamping the drone;

[0013] The reset assembly includes an extension rod, a top rod, a top block, and a spring. The extension rods of the two reset assemblies are fixedly connected to the opposite sides of the clamping rod. The top rod is slidably connected to the extension rod. The top block is fixedly connected to one end of the top rod and is used to abut against the drone. The spring is disposed between the top block and the extension rod.

[0014] In this solution, the landing pad frame holds the drone, and the lifting charging assembly can adjust the height of the charging interface at the top, allowing the drone to be charged through the through-hole in the landing pad. The clamping and fixing assembly clamps the drone with at least one pair of clamping rods, ensuring stability during charging, which is better than simply using support and limiting. The extension rods of the two reset assemblies are fixedly connected to the opposite sides of the clamping rods. By sliding the top rod relative to the extension rod, the distance between the top block and the extension rod can be changed, thereby changing the length of the spring between the top block and the extension rod. The spring force, combined with the top block, abuts the drone, assisting in aligning the drone and making drone charging simpler.

[0015] Preferably, the top block is slidably disposed on the top of the stop plate, which can make the top block more stably abut against the drone by utilizing the limiting position of the stop plate.

[0016] Preferably, one side of the top block is an inclined surface, which is used to adapt to and abut against the landing gear of the drone, so as to better assist the drone in aligning itself.

[0017] Preferably, each pair of clamping rods has a clamping groove on opposite sides, the clamping groove being located above the stop plate, and the clamping groove being used to clamp the horizontal rods on the drone. This makes the clamping and limiting of the drone more stable.

[0018] Preferably, the clamping and fixing assembly further includes a clamping motor, a bidirectional screw, and a sliding groove corresponding to the clamping rod;

[0019] The sliding groove is formed in the stop plate, and the sliding groove is disposed on the outside of the through hole corresponding to the clamping rod;

[0020] The upper part of the clamping rod is located above the stop plate, and the lower part of the clamping rod is located below the stop plate. The upper part of the clamping rod is used to clamp the drone. The clamping rod passes through the corresponding sliding groove and is slidably connected to the inside of the corresponding sliding groove. The clamping rod can slide along the length direction of the sliding groove.

[0021] The clamping motor is located below the stop plate, the bidirectional screw is located below the corresponding sliding groove, the bidirectional screw is fixedly connected to the output end of the clamping motor and rotatably connected to the stop plate frame, and the lower part of the clamping rod is threaded to the bidirectional screw.

[0022] In the above solution, the clamping motor controls the rotation of the bidirectional screw, which in turn drives the clamping rod to move closer to or further away along the length of the bidirectional screw, thus achieving the function of clamping and releasing the drone. The sliding groove limits the movement of the clamping rod, which is beneficial to the accuracy of the clamping process.

[0023] Preferably, a sliding rod is fixedly connected inside the sliding groove and is arranged along the length direction of the sliding groove. The clamping rod is slidably connected to the sliding rod and can slide along the length direction of the sliding rod.

[0024] By using a sliding rod to limit the movement of the clamping rod, the movement of the clamping rod becomes more stable and improves the accuracy of the clamping process.

[0025] Preferably, the charging interface is a charging plug, which is used to connect to the charging socket on the bottom of the drone for quick charging.

[0026] Preferably, the lifting and charging assembly further includes a lifting platform, a charging pile, a support base, a lifting motor, a rotating gear, and a rack disposed below the stop plate;

[0027] The lifting platform is vertically slidably connected to the inside of the helipad frame. The charging pile is located inside the helipad frame. The charging plug is located at the top of the lifting platform and is electrically connected to the charging pile. The support base is fixedly connected to the inside of the helipad frame. The lifting motor is located at the top of the support base. The rotating gear is fixedly connected to the output end of the lifting motor. The rack is fixedly connected to the inner side wall of the lifting platform and meshes with the rotating gear.

[0028] The support base provides a stable mounting space for the lifting motor. The lifting motor drives the rotating gear to rotate, which in turn drives the rack on the inner wall of the lifting platform to rotate, thereby raising and lowering the lifting platform to change the height of the charging plug. This facilitates the landing of the drone on the landing pad and the charging of the drone, while preventing damage to the charging plug when the drone lands on the landing pad.

[0029] Preferably, the system further includes a stabilizing component, which includes a stabilizing groove and stabilizing plates. The stabilizing groove is located on both sides of the lifting platform column, and the two stabilizing plates are fixedly connected to the inner bottom of the helipad frame and slidably connected in cooperation with the stabilizing groove.

[0030] The stabilizing components provide limits and guidance for the lifting of the platform, which helps the charging plug to be accurately inserted into the charging socket on the bottom of the drone, facilitating quick charging.

[0031] Preferably, the bottom of the helipad frame is fixedly connected to multiple mounting plates, and the mounting plates are internally threaded with mounting screws;

[0032] And / or, the top surface of the landing plate is provided with at least two guide lights, which are used to guide the drone to land on the landing plate.

[0033] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0034] 1. This utility model provides a charging device for unmanned aerial vehicles (UAVs) at an airport. The UAV is parked on a parking platform of a helipad frame. A lifting charging component can adjust the height of the charging interface at the top, allowing the UAV to be charged through a through-hole in the parking platform, ensuring the UAV's endurance for the next unmanned flight mission. A clamping and fixing component holds the UAV with at least one pair of clamping rods, ensuring stability during charging, which is better than simply using support and limiting. The extension rods of the two reset components are fixedly connected to opposite sides of the clamping rods. By sliding the top rod relative to the extension rods, the distance between the top block and the extension rods can be changed, thereby changing the length of the spring between the top block and the extension rods. The spring force, combined with the top block's resistance to the UAV, assists in aligning the UAV, making charging the UAV simpler. Attached Figure Description

[0048] Example 1

[0049] like Figure 1 As shown, a charging device for unmanned aerial vehicles (UAVs) airports includes a landing pad frame 1, a lifting and charging assembly 2, a clamping and fixing assembly 4, and a reset assembly 5.

[0050] The helipad frame 1 is equipped with a helipad platform, which is used to support the UAV 208;

[0051] In some embodiments, such as Figure 1As shown, the helipad frame 1 includes an upper top plate, a lower bottom plate, vertical columns connecting the upper bottom plate and the lower bottom plate, and horizontal beams connecting adjacent columns; wherein, the upper top plate is the landing plate, which is set on the top of the helipad frame 1 to facilitate the landing of the UAV 208.

[0052] The top of the lifting and charging assembly 2 is provided with a charging interface, and the height of the charging interface can be adjusted. The stop plate is provided with a through hole adapted to the charging interface.

[0053] The main feature of the lifting and charging component 2 is the lifting and charging interface, which ensures that the charging interface is located below the top surface of the landing plate when the drone lands, so as not to affect the landing of the drone. At the same time, it also avoids damage to the charging interface caused by the drone falling and hitting it. After the drone lands on the top surface of the landing plate, the charging interface can be raised by the lifting and charging component 2, and the drone can be quickly charged through the through hole on the landing plate that is adapted to the charging interface.

[0054] In some embodiments, the charging interface is a charging plug 203, which is used to adapt to and connect to the charging socket 209 at the bottom of the drone 208 for quick plugging and charging.

[0055] In some embodiments, such as Figure 2 and Figure 3 As shown, the lifting and charging assembly 2 also includes a lifting platform 201, a charging pile 202, a support base 204, a lifting motor 205, a rotating gear 206, and a rack 207 disposed below the stop plate;

[0056] The lifting platform 201 is vertically slidably connected to the interior of the helipad frame 1. The charging pile 202 is located inside the helipad frame 1, which is the space below the landing plate and above the lower base plate. The charging plug 203 is located at the top of the lifting platform 201 and electrically connected to the charging pile 202, enabling the charging pile 202 to supply power to the charging plug 203. The support base 204 is fixedly connected to the interior of the helipad frame 1, providing protection and facilitating the structural design of the lifting and charging assembly 2, thus reducing its size. The lifting motor 205 is located at the top of the support base 204, which provides a stable installation space for the lifting motor 205. The rotating gear 206 is fixedly connected to the output end of the lifting motor 205, and the rack 207 is fixedly connected to the inner wall of the lifting platform 201 and meshes with the rotating gear 206. The lifting motor 205 drives the rotating gear 206 to rotate, and the rotation of the rotating gear 206 drives the rack 207 on the inner side wall of the lifting column 201 to rotate, thereby driving the lifting column 201 to rise and fall, thereby changing the height of the charging plug 203, providing convenience for the drone to land on the landing board and for charging the drone, while avoiding damage to the charging plug 203 when the drone lands on the landing board.

[0057] Further optionally, the drone airport charging device also includes a stabilization component 3, such as Figure 4 As shown, the stabilization component 3 includes a stabilization groove 301 and stabilization plates 302. The stabilization groove 301 is located on both sides of the lifting platform 201, and the two stabilization plates 302 are fixedly connected to the inner bottom of the landing pad frame 1 and slidably connected with the stabilization groove 301. The stabilization component 3 can provide limiting and guiding for the lifting of the lifting platform 201, which is conducive to the accurate insertion of the charging plug 203 into the charging socket 209 at the bottom of the drone 208, facilitating quick charging.

[0058] In this embodiment, the clamping and fixing assembly 4 includes at least one pair of clamping rods 404. Each pair of clamping rods 404 is disposed on one opposite side of the through hole, and each pair of clamping rods 404 can clamp the drone 208. The clamping and fixing assembly 4 clamps the drone 208 by at least one pair of clamping rods 404, which can ensure the stability of the drone during charging. Compared with simply using support and limiting, its stability is better. In this embodiment, a pair of clamping rods 404 is provided, such as... Figure 3 As shown, a pair of clamping rods 404 are installed along the length of the apron frame 1.

[0059] In some embodiments, such as Figure 3As shown, each pair of clamping rods 404 has a clamping groove 405 on the opposite side. The clamping groove 405 is located above the stop plate and is used to clamp the horizontal rod on the drone 208, making the clamping and limiting of the drone more stable.

[0060] In some embodiments, such as Figure 3 As shown, the clamping and fixing assembly 4 also includes a clamping motor 402, a bidirectional screw 403, and a sliding groove 401 corresponding to the clamping rod 404;

[0061] The sliding groove 401 is formed in the stop plate, and the sliding groove 401 is disposed on the outside of the through hole corresponding to the clamping rod 404; for example Figure 3 As shown, the sliding groove 401 is arranged along the length of the stop plate, so that the two sliding grooves 401 and the through hole are on the same straight line;

[0062] The upper part of the clamping rod 404 is located above the stop plate, and the lower part of the clamping rod 404 is located below the stop plate. The upper part of the clamping rod 404 is used to clamp the drone 208. Figure 3 As shown, the clamping rod 404 has an inverted L-shaped structure and includes a horizontal bar and a vertical bar. The horizontal bar is arranged along the length direction of the stop plate, and the clamping groove 405 is provided at the end of the horizontal bar facing the through hole of the stop plate. The clamping rod 404 passes through the corresponding sliding groove 401 and is slidably connected to the interior of the corresponding sliding groove 401. The clamping rod 404 can slide along the length direction of the sliding groove 401. Figure 3 In the middle, the vertical rod of the clamping rod 404 passes through the sliding groove 401 and can move along the length of the sliding groove 401;

[0063] The clamping motor 402 is located below the landing plate, and the bidirectional screw 403 is located directly below the corresponding sliding groove 401. The bidirectional screw 403 is fixedly connected to the output end of the clamping motor 402 and rotatably connected to the landing pad frame 1. The lower part of the clamping rod 404 is threadedly connected to the bidirectional screw 403. The clamping motor 402 controls the rotation of the bidirectional screw 403, thereby driving the clamping rod 404 to move closer to or further away from the length of the bidirectional screw 403, realizing the function of clamping and releasing the UAV. The sliding groove 401 limits the movement of the clamping rod 404, which is beneficial to the accuracy of the clamping process.

[0064] Furthermore, a sliding rod 6 is fixedly connected inside the sliding groove 401, extending along the length of the sliding groove 401. The clamping rod 404 is slidably connected to the sliding rod 6, and the clamping rod 404 can slide along the length of the sliding rod 6. The sliding rod 6 limits the movement of the clamping rod 404, making its movement more stable and improving the accuracy of the clamping process.

[0065] Each clamping rod 404 has a reset assembly 5 on its opposite sides. The reset assembly 5 includes an extension rod 501, a top rod 502, a top block 503, and a spring 504. The extension rods 501 of the two reset assemblies 5 are fixedly connected to the opposite sides of the clamping rod 404. The top rod 502 is slidably connected to the extension rod 501. The top block 503 is fixedly connected to one end of the top rod 502 and is used to abut against the drone 208. The spring 504 is disposed between the top block 503 and the extension rod 501. The top rod 502 passes through the extension rod 501 and can slide within the through hole of the extension rod 501. A limiting boss is provided at the other end of the top rod 502 to prevent it from sliding out of the through hole of the extension rod 501.

[0066] like Figure 5 and Figure 6 As shown, the extension rods 501 of the two reset components 5 are fixedly connected to the opposite sides of the clamping rod 404. By sliding the top rod 502 relative to the extension rod 501, the distance between the top block 503 and the extension rod 501 can be changed, thereby changing the length of the spring 504 between the top block 503 and the extension rod 501. The force of the spring 504 cooperates with the top block 503 to abut against the drone 208, assisting the drone in aligning itself and making drone charging simpler.

[0067] Alternatively, the top block 503 is slidably disposed on the top of the stop plate, which can utilize the limiting position of the stop plate to make the top block more stably abut against the drone 208.

[0068] Further, one side of the top block 503 is an inclined surface, which is used to adapt to and abut against the landing gear of the drone 208, so as to better assist the drone in straightening.

[0069] In some embodiments, a plurality of mounting plates 7 are fixedly connected to the bottom of the helipad frame 1, and mounting screws 8 are threaded onto the interior of the mounting plates 7. In some embodiments, at least two guide lights 9 are provided on the top surface of the helipad plate, and the guide lights 9 are used to guide the drone 208 to land on the helipad plate. In use, the mounting plates 7 and mounting screws 8 facilitate the installation and fixation of the helipad frame 1, and the guide lights 9 provide guidance for the landing of the drone 208.

[0070] Using the drone airport charging device of this embodiment, when a drone 208 lands and rests on the parking plate at the top of the parking apron frame 1, the clamping motor 402 is activated, driving the bidirectional screw 403 to rotate. This causes the clamping rod 404 to slide on the sliding rod 6 inside the sliding groove 401, causing the clamping groove 405 to lock the drone 208 in place, thereby clamping and positioning the drone 208. At the same time, the top blocks 503 on both sides of the clamping rod 404 will press against the bottom of the drone 208 and be spring-loaded by the spring 504. The force is used to adjust the orientation of the drone 208, so that the drone 208 is aligned to facilitate subsequent charging operations; then the lifting motor 205 is started, which drives the rotating gear 206 to rotate, and then the rack 207 that meshes with the rotating gear 206 drives the lifting column 201 to slide inside the landing pad frame 1. The stabilizing groove 301 is limited by the stabilizing plate 302, and the lifting column 201 drives the charging plug 203 to be inserted into the charging socket 209 of the drone 208, thereby charging the drone 208.

[0071] The drone airport charging device of this embodiment, through the setting of clamping and fixing components and reset components, realizes the function of quickly clamping and limiting the drone that has landed on the apron frame, and can also straighten the drone's direction to facilitate subsequent charging operations. It solves the problem in the prior art that the drone cannot be fixed and its position can be straightened, which makes it inconvenient to charge the drone.

[0072] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
