Description

Technical Field

[0001] This invention relates to a landing pad for unmanned aerial vehicles (UAVs), belonging to the field of UAV landing pad manufacturing technology. Background Technology

[0002] A drone helipad is a dedicated area for parking and taking off / landing small drones. Compared to large drone helipads, small drone helipads are usually simpler and more flexible, suitable for personal or small-scale drone operations. Small drone helipads are relatively small, typically ranging from tens to hundreds of square meters. The helipad is generally circular, square, or rectangular, with the specific shape depending on the user's needs and site conditions. The surface of the helipad is made of flat and sturdy materials, providing stable support and making drone take-off and landing safer.

[0003] Currently, common drone landing pads are typically used in outdoor environments with high levels of interference, such as grasslands, sandy areas, and soil. Due to the uneven surface and the presence of debris and dust, drone takeoff can be restricted. While landing pads provide a relatively flat space for takeoff and landing, the contact area between the landing pad and the ground is usually flat or at a right angle. When the ground is tilted or uneven, the landing pad cannot remain level, which can affect drone takeoff and landing. Additionally, common landing pads typically use wireless charging for drone charging. Drones can be wirelessly charged as soon as they land on the landing pad. However, because wireless charging is slow, drones need to remain on the landing pad for extended periods, exposed to the outside environment, making them susceptible to dust contamination and unable to quickly replenish their charge.

[0004] Patent CN115743664B discloses a portable drone landing pad. This invention uses two infrared ranging sensors to detect the drone's position on the landing platform. A lateral clamping component and a deflection component adjust the angle between the drone and the platform, allowing the drone to quickly reach the correct parking posture. The platform is equipped with a protective, automatically folding shield and a charging plug, enabling the drone to park normally and perform data interaction and charging in various weather conditions. A pole and deflection rod are installed at the base of the landing pad for fixation. However, while using a charging plug to replenish the drone's power is faster than wireless charging, the drone still needs to remain on the platform for charging. Although the automatically folding shield reduces dust intrusion, it also makes the structure more complex and susceptible to damage from external influences. The combination of the pole and deflection rod can stabilize the landing pad in the soil, but a single pole needs to be inserted deep into the soil to maintain the center of gravity and prevent the landing pad from tipping over.

[0005] Patent CN112722306A discloses a drone landing pad. This invention sets up several landing positions, with wireless charging landing positions at different heights, allowing any wireless charging landing position to overlap or unfold with adjacent positions. A scraper ring is installed below the upper landing positions. When the wireless charging landing positions overlap, the scraper ring can protect them, and when unfolded, it can clean them and remove foreign objects. However, while this solution can wirelessly charge multiple drones, it does not improve the charging efficiency of a single drone. It cannot quickly recharge drones, requiring drones to stay on the landing positions for extended periods to charge. Although the scraper ring can clean the landing positions, it cannot protect against dust or debris during the drone charging process.

[0006] The drone landing pads in the aforementioned published patents cannot quickly recharge drones, requiring them to remain on the landing pad for extended periods to charge. They are also susceptible to dust and debris, and the landing pads have poor support from the ground, which can cause them to tilt and affect drone takeoff and landing. Summary of the Invention

[0007] To address the shortcomings of the existing technology, this invention provides a drone landing pad that solves the problems of common drone landing pads, such as the inability to quickly recharge drones and the poor support effect between the landing pad and the ground, making it difficult to maintain a level position.

[0008] The objective of this invention is achieved through the following technical solution: a landing pad for unmanned aerial vehicles (UAVs) includes a bottom support plate, with two outer shells facing each other above the bottom support plate. The invention is characterized by: four trapezoidal connecting blocks above the two outer shells, the trapezoidal connecting blocks being connected to the outer shells by screws; a landing platform inside the four trapezoidal connecting blocks; a central mounting plate below the landing platform; limit lifting devices at the four corners of the central mounting plate; a battery below the central mounting plate; battery charging compartments on both sides of the battery; a charging compartment pushing device below each of the two battery charging compartments; support feet at the four outer corners of the central mounting plate; and a closed cover above the four trapezoidal connecting blocks.

[0009] Furthermore, the parking platform includes a mounting plate with a circular parking platform on its inner side. The circular parking platform is connected to the mounting plate by screws. The mounting plate has four indicator light strips, all of which are connected to the mounting plate by snap-fit ​​connections. A landing signal transmitter is located on the side of each indicator light strip and is connected to the mounting plate by screws. Both the indicator light strips and the landing signal transmitter are electrically connected to the battery. Two L-shaped support frames are located below the mounting plate and are connected to the mounting plate by screws. The four indicator light strips are connected to the mounting plate by snap-fit ​​connections for easy and quick installation and replacement. The landing signal transmitter is also located on the side of the indicator light strips, providing a landing signal and warning / guidance function. The two L-shaped support frames are connected to the bottom of the mounting plate by screws, providing additional support and stability to ensure the stability of the parking platform.

[0010] Furthermore, the circular landing platform includes a circular platform with a charging coil inside. The charging coil is connected to the circular platform via a snap-fit ​​mechanism. A pressure sensor is located inside the charging coil and is connected to the circular platform via screws. A circuit connection board is located below the charging coil and is connected to the circular platform via a snap-fit ​​mechanism. The charging coil can be used for wireless charging of the drone. The pressure sensor can detect whether the drone has landed on the circular landing platform. When the drone leaves the circular landing platform, the charging function will automatically shut off to avoid current leakage and safety hazards.

[0011] Furthermore, the limiting lifting device includes two electric telescopic rods, each with two limiting slide rods on its sides. The output end of each electric telescopic rod is connected to the corresponding L-shaped support frame above it via screws. The machine mounting plate and the L-shaped support frame have arc-shaped grooves at the limiting slide rods. A slide rod fixing block is located below the limiting slide rod. The middle mounting plate is connected to the slide rod fixing block and the electric telescopic rod via screws. Both the slide rod fixing block and the electric telescopic rod are connected to the bottom support plate via screws. By controlling the electric telescopic rods, the machine mounting plate can be easily raised and lowered. The connection between the output end of the electric telescopic rod and the L-shaped support frame via screws ensures the stable support of the machine mounting plate, giving it a strong load-bearing capacity. The design of the limiting slide rods and the arc-shaped grooves allows the machine mounting plate to maintain a fixed travel path during the raising and lowering process.

[0012] Furthermore, the battery charging compartment includes two compartments, each containing a battery insertion slot. Both compartments are electrically connected to the battery. Two square limiting sliders are located below each compartment, connected to the compartments by screws. One compartment contains three small battery insertion slots, while the other contains a large battery insertion slot. The battery charging compartment has battery insertion slots of different sizes to accommodate different types and specifications of batteries. The square limiting sliders are connected to the bottom of the battery charging compartment by screws, restricting the sliding direction of the battery charging compartment while maintaining sliding stability.

[0013] Furthermore, the charging compartment pushing device includes a compartment connecting block, which is connected to the compartment by screws. One end of the compartment connecting block has an arc-shaped contact surface, and the other end has a small electric telescopic rod. Support crossbars are provided on both sides of the small electric telescopic rod. One side of each support crossbar is connected to the electric telescopic rod or the sliding rod fixing block by screws. One end of each support crossbar is connected to the small electric telescopic rod by screws. Limiting slide rails are provided in the middle of each support crossbar, and the two limiting slide rails are located outside the two limiting slide rails. One end of each of the limiting slide rails is fixedly connected to the supporting crossbar, and the other end of each of the two limiting slide rails is provided with an arc-shaped contact surface. A flip-closing plate is provided between the two limiting slide rails. The charging compartment pushing device, through the design of the compartment connecting block and the small electric telescopic rod, can steadily and quickly push the battery charging compartment. The connection between the supporting crossbar and the limiting slide rail further enhances the stability of the device. At the same time, it works with the square limiting slider to maintain the sliding stability of the battery charging compartment. The design of the flip-closing plate ensures that the battery charging compartment is protected when it is inside the device. When the battery charging compartment is pushed out, it can be flipped open to facilitate the removal of the battery.

[0014] Furthermore, the flip-up closing plate includes a closing plate with one side being an inclined surface and notches at both ends of the other side. A circular shaft mounting block is provided inside the notch, and the circular shaft mounting block is connected to the closing plate by screws. One side of the circular shaft mounting block has an arc-shaped contact surface, and a rotating circular shaft is fixedly mounted on one end of the circular shaft mounting block. The rotating circular shaft passes through the limiting slide rail, and a torsion spring is provided on the outside of the rotating circular shaft. One end of the torsion spring is connected to the limiting slide rail by inserting a metal wire, and the other end of the torsion spring is connected to the rotating circular shaft by inserting a metal wire. The inclined surface of one side of the closing plate and the arc-shaped contact surface of the circular shaft mounting block reduce friction with the outer casing and other components, preventing damage. The torsion spring, connected to the limiting slide rail and the rotating circular shaft by inserting a metal wire, provides strong support while allowing the closing plate to automatically return to its closed position when the pressure is lost, protecting the inside of the equipment from dust intrusion.

[0015] Furthermore, the support foot includes a grounding rod that penetrates the bottom support plate. One end of the grounding rod is a sloping pressure foot, and the other end is provided with a sleeve. The grounding rod is fitted inside the sleeve, and one end of the sleeve is connected to the trapezoidal connecting block by screws. A propulsion ring is provided on the outside of the grounding rod, and the propulsion ring is fixedly connected to the grounding rod. A limiting ring is provided on the side of the propulsion ring, and the limiting ring is located below the bottom support plate and is connected to the bottom support plate by screws. A pressure spring is provided between the propulsion ring and the sleeve. When the ground is uneven, the grounding rod retracts upward into the sleeve due to ground pressure and equipment weight, causing the propulsion ring to squeeze the pressure spring and tighten it. Because the spring pressure and the unevenness of the ground cause the four grounding rods to retract to different lengths, the apron maintains a level and stable effect.

[0016] Furthermore, the closing cover includes two square cover plates, each of which has two sliding grooves. Each of the two sliding grooves has a cylindrical slide rail block. The four cylindrical slide rail blocks pass through the trapezoidal connecting block and are connected by threads. Each of the two square cover plates has a handle. The closing cover plate slides smoothly on the cylindrical slide rail blocks through the sliding grooves, making the opening and closing process smoother and easier.

[0017] Furthermore, one end of the battery is provided with a charging port, which penetrates the outer casing and is connected by screws. A charging indicator light is provided on the side of the charging port. A press-type circuit connector is provided above the middle mounting plate. The press-type circuit connector is electrically connected to the battery. After the circuit connection plate presses down on the press-type circuit connector, the current in the battery is transmitted to the charging coil through the press-type circuit connector and the circuit connection plate. A charging indicator light is also provided on the side of the charging port, which can display the charging status and remaining power in real time. After the electric telescopic rod drives the stopping platform to press down on the press-type circuit connector, the current in the battery can be transmitted to the charging coil through the press-type circuit connector and the circuit connection plate, realizing a stable and reliable circuit connection while avoiding power consumption caused by maintaining a continuous connection.

[0018] In summary, compared with the prior art, the present invention has the following advantages:

[0019] 1. In this invention, a lifting space for the landing platform is reserved on the inner side of the landing pad. The landing platform is lifted and lowered by an electric telescopic rod. With the help of a tightly closed cover, a drone storage space is formed inside the landing pad. After the drone stops flying, it can be stored in the space. After the landing platform presses down on the push-button circuit connector, the charging coil is connected to the battery circuit to wirelessly charge the drone. The closed storage space can also protect the drone from dust.

[0020] 2. In this invention, when the drone needs to be quickly recharged after landing, the small electric telescopic rod is activated to push the battery charging compartment outward. The limiting slide rail and the square limiting slider can restrict the direction of travel of the battery charging compartment to prevent track deviation. After the battery charging compartment travels a certain distance, the flip-up closing plate is pushed open, and the battery can be taken out from the battery insertion slot of the battery charging compartment to replace the battery in the drone, thus completing the quick recharge. The drone does not need to stay in the wireless charging area for a long time for wireless charging.

[0021] 3. In this invention, support legs are provided below the helipad. When the helipad is placed on a flat surface, the support legs retract upwards due to the weight of the helipad. The propulsion ring moves upwards and compresses the pressure spring of the sleeve, causing it to tighten. Because the ground is flat, the four pressure springs are evenly stressed, keeping the retraction length of the support legs consistent and keeping the helipad level. When the helipad is placed on an uneven surface, the weight of the helipad, the unevenness of the ground, and the spring pressure cause the four support legs to retract to different lengths, maintaining the levelness of the helipad and facilitating the take-off and landing of UAVs.

[0040] Combination Figure 5 As shown, the battery charging compartment 7 includes two compartments 71, each containing a battery insertion slot 72. The two compartments 71 are electrically connected to the battery 6. Each compartment 71 has two square limiting sliders 73 at its bottom, which are connected to the compartments 71 by screws. One compartment 71 contains three small battery insertion slots 72, while the other compartment 71 contains a large battery insertion slot 72. The battery charging compartment 7 has battery insertion slots 72 of different sizes to accommodate different types and specifications of batteries. The battery charging compartment 7 is connected to the square limiting sliders 73 at its bottom by screws, which restricts the sliding direction of the battery charging compartment 7 while maintaining sliding stability.

[0041] Combination Figure 5 and Figure 6 As shown, the charging compartment pushing device 8 includes a compartment connecting block 81, which is connected to the compartment 71 by screws. One end of the compartment connecting block 81 has an arc-shaped contact surface, and the other end of the compartment connecting block 81 has a small electric telescopic rod 82. Both sides of the small electric telescopic rod 82 have supporting crossbars 83. One side of each of the two supporting crossbars 83 is connected to the electric telescopic rod 51 or the sliding rod fixing block 53 by screws. One end of each of the two supporting crossbars 83 is connected to the small electric telescopic rod 82 by screws. Each of the two supporting crossbars 83 has a limiting slide rail 84 in the middle. The two limiting slide rails 84 are located outside the two limiting slide rods 52. One end of each is fixedly connected to the support crossbar 83, and the other end of each of the two limiting slide rails 84 is provided with an arc-shaped contact surface. A flip-closing plate 85 is provided between the two limiting slide rails 84. The charging compartment pushing device 8, through the design of the compartment connecting block 81 and the small electric telescopic rod 82, can push the battery charging compartment 7 steadily and quickly. The connection between the support crossbar 83 and the limiting slide rail 84 further enhances the stability of the device. At the same time, it cooperates with the square limiting slider 73 to maintain the sliding stability of the battery charging compartment 7. The design of the flip-closing plate 85 ensures that the battery charging compartment 7 is protected when it is inside the device.

[0042] Combination Figure 5 and Figure 6As shown, the flip-up closing plate 85 includes a closing plate 851. One side of the closing plate 851 is a slope, and both ends of the other side of the closing plate 851 have notches 852. A round shaft mounting block 853 is provided inside the notch 852. The round shaft mounting block 853 is connected to the closing plate 851 by screws. One side of the round shaft mounting block 853 is an arc-shaped contact surface. A rotating round shaft 854 is fixedly provided at one end of the round shaft mounting block 853. The rotating round shaft 854 passes through the limiting slide rail 84. A torsion spring 855 is provided on the outside of the rotating round shaft 854. One end of the torsion spring 855 is connected to the limiting slide rail 84. The torsion spring 855 is connected to the rotating shaft 854 by inserting a metal wire. One side of the closing plate 851 is inclined and the other side of the shaft mounting block 853 is an arc-shaped contact surface. The inclination of the inclined surface and the arc-shaped contact surface can reduce friction with the outer shell 2 and other components to avoid damage.

It provides strong support force and allows the closing plate 851 to return to its closed position when the pressure force is lost, protecting the inside of the equipment from dust.

[0043] Combination Figure 1 and Figure 7 As shown, the support foot 9 includes a grounding rod 91, which passes through the bottom support plate 1. One end of the grounding rod 91 is a sloping pressure foot, and the other end of the grounding rod 91 is provided with a sleeve 92. The grounding rod 91 is fitted inside the sleeve 92. One end of the sleeve 92 is connected to the trapezoidal connecting block 21 by screws. A push ring 93 is provided on the outside of the grounding rod 91. The push ring 93 is fixedly connected to the grounding rod 91. A limit ring 94 is provided on the side of the push ring 93. The limit ring 94 is located below the bottom support plate 1 and is connected to the bottom support plate 1 by screws. A pressure spring 95 is provided between the push ring 93 and the sleeve 92. When the ground is uneven, the grounding rod 91 is retracted upward into the sleeve 92 due to the ground pressure and the weight of the equipment. This causes the push ring 93 to squeeze the pressure spring 95, tightening the spring. Due to the spring pressure and the unevenness of the ground, the four grounding rods 91 retract to different lengths, thus maintaining the levelness of the helipad.

[0044] Combination Figure 1 and Figure 8 As shown, the closing cover 22 includes two square cover plates 221. Each of the two square cover plates 221 is provided with two sliding grooves 222. Each of the two sliding grooves 222 is provided with a cylindrical slide rail block 223. The four cylindrical slide rail blocks 223 pass through the trapezoidal connecting block 21 and are connected by threads. Each of the two square cover plates 221 is provided with a handle 224. The closing cover 22 slides smoothly on the cylindrical slide rail block 223 through the sliding grooves 222, making the opening and closing process smoother and easier.

[0045] Combination Figure 1 and Figure 9As shown, one end of the battery 6 is provided with a charging port 61, which passes through the outer casing 2 and is connected by screws. A charging indicator light 62 is provided on the side of the charging port 61. A press-type circuit connector 63 is provided above the middle mounting plate 4. The press-type circuit connector 63 is electrically connected to the battery 6. After the circuit connection plate 324 presses down on the press-type circuit connector 63, the current in the battery 6 is transmitted to the charging coil 322 through the press-type circuit connector 63 and the circuit connection plate 324. The side of the charging port 61 is also provided with a charging indicator light 62, which can display the charging status and remaining power in real time. After the electric telescopic rod 51 drives the stopping platform 3 to press down on the press-type circuit connector 63, the current in the battery can be transmitted to the charging coil 322 through the press-type circuit connector 63 and the circuit connection plate 324, realizing a stable and reliable circuit connection while avoiding power consumption caused by maintaining a continuous connection.

[0046] Working principle: When not in use, the helipad is placed on the ground. When the helipad is placed on a flat surface, the support legs retract upwards due to the weight of the helipad. The propulsion ring moves upwards and compresses the pressure spring of the sleeve, causing it to tighten. Because the ground is flat, the four pressure springs are evenly stressed, keeping the support legs retracted to the same length and keeping the helipad level. When the helipad is placed on an uneven surface, the weight of the helipad, the unevenness of the ground, and the spring pressure cause the four support legs to retract to different lengths, maintaining the level of the helipad. The drone is stored inside the helipad. When in use, the square cover is pulled open to both sides by holding the handle. The electric telescopic rod is activated to push the helipad platform upwards along the limit slide bar. The circuit connection board is disengaged from the press-type circuit connector, the charging coil is de-energized, and when the helipad platform rises to be level with the trapezoidal connecting block, the drone can be controlled to take off.

[0047] When the drone lands, the marker light strip provides warning and marker effects, which can prevent the drone from landing incorrectly due to poor visibility. When the drone is operated incorrectly, the landing signal transmitter sends a signal to guide the drone to land on the parking platform. When the drone needs to be recharged after landing, the small electric telescopic rod is activated to push the battery charging compartment to slide outward along the limit slide rail. The flip-up closing plate is pushed open, the torsion spring deforms, and the battery is taken out from the battery insertion slot to replace the drone battery. This enables quick battery replacement for the drone. When the depleted battery is placed in the battery insertion slot for charging, the small electric telescopic rod drives the battery charging compartment to retract, and the torsion spring drives the closing plate to return to its original position to form a seal.

[0048] After the flight, the drone rests on the parking platform. The electric telescopic boom lowers the platform until the circuit board and the push-button circuit connector press together to connect the circuit. The pressure sensor detects the pressure on the drone and activates the charging coil to wirelessly charge the drone. After the top cover closes, the interior becomes the drone storage compartment.

[0049] The embodiments of the present invention are not limited to those described above. Without departing from the spirit and scope of the present invention, those skilled in the art can make various changes and improvements to the present invention in form and detail, and these are all considered to fall within the protection scope of the present invention.
