Description

Technical Field

[0001] This utility model belongs to the field of aircraft take-off and landing facilities, specifically an embedded small low-altitude aircraft take-off and landing pad. Background Technology

[0002] With the rapid penetration of the low-altitude economy into urban logistics, public safety inspection, and emergency medical delivery, the demand for take-off and landing facilities for the large-scale application of small low-altitude aircraft (such as logistics drones and inspection drones) is becoming increasingly urgent. However, current low-altitude aircraft take-off and landing facilities in urban environments are inadequate in terms of space utilization and structural protection, making it difficult to meet the actual needs of cities with limited land resources and complex and diverse scenarios.

[0003] Existing take-off and landing facilities are mainly divided into two categories: one is fixed aprons. Although these facilities integrate functions such as charging and dispatching, they require independent ground space (such as dedicated sites or rooftop platforms), resulting in high construction costs and poor flexibility. They are almost impossible to deploy in densely populated urban core areas, narrow sidewalks, community squares, and other areas with scarce land resources, leading to a take-off and landing facility coverage rate far below actual operational needs. The other category is simple temporary ground take-off and landing points, which are mostly marked by ground spray-painted lines without any physical protective structures. Not only are aircraft susceptible to wind, rain, debris, or human interference when landing, but these take-off and landing points also remain as "idle ground space" when not in use, failing to achieve reuse with daily urban spaces and further wasting limited urban land resources. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an embedded small low-altitude aircraft take-off and landing pad, which solves the problems of insufficient urban low-altitude aircraft take-off and landing facilities, high construction costs, large land area, and insufficient protection for aircraft in the existing technology.

[0005] An embedded small low-altitude aircraft take-off and landing pad includes:

[0006] Protective case with a hinged top cover;

[0007] The helipad is slidably housed within a protective casing and can move along the Z-axis;

[0008] The lifting assembly, housed within the protective housing, is used to drive the helipad to rise and fall along the Z-axis;

[0009] The transmission structure, located between the side of the helipad and the protective shell, is used to convert the lifting motion of the helipad into the rotation of the upper cover around the hinge point.

[0010] Preferably, the landing pad includes a take-off and landing pad, which is equipped with a wireless charging transmitter, a charging interface and guidance signs, and a functional module compartment on the lower surface, which houses a control module and a communication module.

[0011] Preferably, the top cover includes two oppositely arranged cover plates, each cover plate having a pivot at both ends, the pivot being hinged to the top of the protective shell, and a rubber sealing strip on the inner edge.

[0012] Preferably, the lifting assembly is one of an electric scissor lift or an electric screw lift mechanism.

[0013] Preferably, the transmission structure includes a transmission component and a linkage component. The transmission component includes a connecting shaft rotatably disposed within the protective housing and transmission shafts at both ends. The connecting shaft and the transmission shaft are connected through a synchronous transmission unit.

[0014] Preferably, the linkage component includes a rack fixed to the side of the landing pad and a transmission gear fixedly sleeved on the connecting shaft, wherein the transmission gear meshes with the rack.

[0015] Preferably, the synchronous transmission unit is a synchronous belt or chain transmission unit.

[0016] Preferably, the protective shell is provided with a gear transmission box, the input end of which is connected to the transmission structure and the output end is connected to the upper cover, so as to realize the linkage of the upper cover opening when the helipad rises and closing when it falls.

[0017] Preferably, the guidance markings include a reflective center positioning point, a heading guide line, and a boundary warning line, and the charging interface includes a Type-C interface and an aviation plug.

[0027] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0028] As attached Figure 1 To be continued Figure 3 As shown:

[0029] This utility model provides an embedded small low-altitude aircraft take-off and landing pad, including a protective shell 1, a landing pad 2, a top cover 3, a lifting assembly 4, a transmission assembly 6, a linkage assembly 5, and a gear transmission box 7, so as to realize the embedded installation, automatic opening and closing, lifting, charging, and guidance functions of the take-off and landing pad.

[0030] As attached Figure 1 To be continued Figure 3 As shown: Protective shell 1 is the core load-bearing structure for embedded installation. It adopts a U-shaped cavity design, is made of cast concrete, and has stainless steel plates lining the inner wall with waterproofing treatment. It is buried below the urban ground level (such as sidewalks or plaza edges), with the top edge flush with the ground.

[0031] As attached Figure 1 To be continued Figure 3 As shown: The inner wall of the protective shell 1 is symmetrically welded with guide rails, which cooperate with the guide slider of the landing pad 2 to ensure smooth and stable lifting and lowering. A pivot mounting seat is pre-installed at the top edge of the protective shell 1 for hinged connection to the upper cover 3. The mounting seat contains a bushing to reduce rotational friction during pivoting. A steel plate pre-embedded part is embedded at the bottom center of the protective shell 1 to fix the lifting assembly 4. The pre-embedded part is welded and fixed to the steel reinforcement frame of the protective shell 1 to meet the take-off and landing load requirements of small and medium-sized unmanned aerial vehicles.

[0032] As attached Figure 1 To be continued Figure 3 As shown: The landing pad 2 is the core component for aircraft takeoff and landing and functional integration, including the landing pad 201, wireless charging transmitter 202, charging interface 8, and functional module bay. The landing pad 201 is made of high-strength aluminum alloy sheet by stamping, and the surface is coated with a wear-resistant coating. The landing pad 201 has a size of 2m × 2m, which is suitable for most small low-altitude aircraft.

[0033] As attached Figure 1 To be continued Figure 3 As shown: The upper surface of the landing pad 201 is affixed with reflective guidance markings (using 3M ultra-high reflective film), including a center positioning point, a heading guide line, and boundary warning lines. These markings can be identified by the aircraft's vision system at night or in low-light conditions, improving guidance accuracy. A wireless charging transmitter 202 (using magnetic resonance coupling technology) is embedded in the central area of ​​the landing pad 201, with an effective charging distance of ≤15cm, meeting the wireless charging needs of mainstream drones.

[0034] As attached Figure 1 To be continued Figure 3 As shown: One edge of the landing pad 201 integrates charging ports 8, including a Type-C interface and an aviation plug. The interfaces are equipped with waterproof and dustproof covers to meet the aircraft's wired charging or emergency power supply needs. A functional module bay is bolted to the lower surface of the landing pad 201. The bay integrates a control module (STM32 series chip processor), a cellular / Bluetooth communication module, and an attitude sensor. The control module wirelessly connects to a remote dispatch platform via the communication module, enabling remote start / stop, status monitoring, and fault alarms. The attitude sensor monitors the landing pad's levelness in real time, automatically triggering an alarm when the tilt angle exceeds 3° to ensure safe takeoff and landing. The cellular communication can be either 4G or 5G.

[0035] As attached Figure 1 To be continued Figure 3 As shown: The upper cover 3 is the opening and closing structure protecting the helipad, including two symmetrically arranged cover plates 301 and a pivot 302. The cover plates 301 are made of carbon fiber composite material molding or high-strength lightweight alloy steel plate, with a single piece size of 2.15m × 1m, which has the advantages of high strength and lightweight. The upper surface of the cover plates 301 is pasted with paving materials consistent with the ground (such as sidewalk tiles or plaza stones), so that when closed, it blends into the surrounding environment and has no visual abruptness.

[0036] Both ends of the cover plate 301 are welded with rotating shafts 302. The rotating shafts 302 are hinged to the top edge of the protective shell 1 via bearing seats. The overall thickness of the cover plate 301 is greater than 15mm, and reinforcing ribs are added to the bottom surface to improve overall strength. One end of the rotating shaft 302 extends to the inside of the protective shell 1 and is connected to the output shaft of the gear transmission box 7 via a coupling to achieve power transmission. A sealing strip is affixed to the inner edge of the cover plate 301, which fits tightly against the top edge of the protective shell 1 when closed to prevent rainwater and dust from entering the interior of the protective shell 1.

[0037] As attached Figure 2 To be continued Figure 3 As shown: The lifting assembly 4 is the power unit that drives the helipad 2 to lift. It can be either an electric scissor lift or an electric screw lift mechanism. This embodiment uses an electric scissor lift, including a scissor frame 401, a linear actuator 402, a guide rod 403, a movable seat 404, and a fixed seat 405. The fixed seat 405 is fixed to the embedded parts at the bottom of the protective shell 1 by bolts. The scissor frame 401 is composed of multiple sets of cross-hinged high-strength aluminum alloy profiles, and the intersection points are connected by pins to ensure flexible rotation.

[0038] As attached Figure 2 To be continued Figure 3 As shown: The linear actuator 402 is an electric push rod, with one end hinged to the fixed base 405 and the other end hinged to the middle intersection point of the scissor frame 401. It extends or retracts the scissor frame 401 via telescopic drive. The movable base 404 is hinged to the top of the scissor frame 401, and its top is fixed to the lower surface of the lifting platform 201 by bolts. Guide sliders are installed on both sides of the movable base 404, slidingly engaging with the guide rails of the protective shell 1. The guide rods 403 are two parallel rods with anti-corrosion and anti-rust coatings on their surfaces. Their ends are fixed to the fixed base 405 and the movable base 404 respectively, ensuring that the scissor frame 401 does not shift laterally during lifting. When the lifting assembly 4 is fully raised, the upper surface of the lifting platform 201 is higher than the surrounding ground, facilitating drainage. When fully lowered, the upper cover 3 can be completely closed.

[0039] As attached Figure 2 To be continued Figure 3As shown: Through the cooperation of the transmission component 6 and the linkage component 5, the linear motion of the lifting component 4 is converted into the rotational motion of the upper cover 3, realizing the "lifting-opening" linkage. The transmission component 6 includes a connecting shaft 601, a transmission shaft 602, and a synchronous transmission unit 603. The connecting shaft 601 is horizontally mounted in the middle of the inner wall of the protective shell 1 through a bearing seat, and its axis is parallel to the length direction of the protective shell 1. There are two transmission shafts 602, symmetrically arranged at both ends of the connecting shaft 601. One end of the transmission shaft 602 is connected to the connecting shaft 601 through the synchronous transmission unit 603 (selected as a synchronous belt transmission unit), and the other end is connected to the input shaft of the gear transmission box 7 through a coupling. The synchronous transmission unit 603 includes a driving synchronous pulley, a driven synchronous pulley, and a synchronous belt. The driving synchronous pulley is keyed to the connecting shaft 601, and the driven synchronous pulley is keyed to the transmission shaft 602 to ensure zero-slip power transmission.

[0040] As attached Figure 2 To be continued Figure 3 As shown: The linkage component 5 includes a transmission gear 501 and a rack 502. The rack 502 is elongated and is vertically fixed to the side of the lifting platform 201 (on the same side as the guide slider) by bolts. The transmission gear 501 is keyed to the middle of the connecting shaft 601 and meshes with the rack 502. When the lifting platform 201 is raised or lowered, the rack 502 drives the transmission gear 501 to rotate, which in turn drives the transmission shaft 602 to rotate through the connecting shaft 601 and the synchronous transmission unit 603.

[0041] As attached Figure 1 To be continued Figure 3 As shown: Gear transmission box 7 is used to change the transmission direction and amplify torque. It is installed on the inner wall of the protective shell 1 near the rotating shaft 302. Its input shaft is connected to the transmission shaft 602, and its output shaft is connected to the rotating shaft 302 of the cover plate 301. The gear transmission box 7 uses parallel shaft gears to convert the rotational motion of the transmission shaft 602 into the rotational motion of the rotating shaft 302, while amplifying the torque to ensure the smooth opening and closing of the cover plate 301. The outer shell of gear transmission box 7 is made of die-cast aluminum alloy and filled with grease. The outer shell has an IP65 protection sealing rating, which is suitable for humid underground environments. When the lifting assembly 4 drives the lifting platform 201 to rise, the rack 502 drives the transmission gear 501 to rotate, which is transmitted to the rotating shaft 302 through the transmission assembly 6 and gear transmission box 7, so that the two cover plates 301 open outwards synchronously (opening angle 120°~170°); when the lifting platform 201 descends, the cover plates 301 close inwards synchronously, realizing the linkage function of "rising-opening" and "falling-closing".

[0042] Working principle: The landing pad 2 descends completely into the protective shell 1, the top cover 3 closes, and the cover plate 301 is flush with the ground. The interior of the protective shell 1 is sealed, effectively protecting against dust, rain, and foreign objects. The control module is in low-power standby mode, receiving remote commands through the communication module, and the attitude sensor monitors the equipment's levelness in real time to ensure it is always available.

[0043] Upon receiving a take-off or landing command, the control module activates the linear actuator 402 of the lifting assembly 4, which extends to drive the scissor frame 401 to unfold, causing the landing platform 2 to rise along the guide rail. Simultaneously, the rack 502 on the side of the landing platform 2 rises in sync, and the transmission gear 501 meshing with the rack 502 rotates. Power is transmitted via the connecting shaft 601 to the synchronous transmission units 603 at both ends, driving the transmission shaft 602 to rotate. The transmission shaft 602 changes the transmission direction through the gear transmission box 7, causing the rotating shaft 302 of the cover plate 301 to rotate, so that the two cover plates 301 open outwards symmetrically until the landing platform 2 rises to its position.

[0044] After the landing pad 2 reaches its designated position, the control module illuminates the guidance markers and activates the wireless charging transmitter 202. The aircraft then uses its visual guidance system to identify the positioning point and achieve a precise landing. Depending on the aircraft's needs, wireless charging (via the wireless charging transmitter 202) or wired charging (via the charging interface 8) can be selected. The control module monitors the charging current and voltage in real time and automatically cuts off power once fully charged.

[0045] After the aircraft takes off, the control module drives the linear actuator 402 to retract, the scissor frame 401 to fold, and the landing pad 2 descends along the guide rail. The rack 502 descends synchronously, driving the transmission gear 501 to rotate in the opposite direction. Power is transmitted through the transmission assembly 6 and the gear transmission box 7, causing the cover plate 301 to rotate inward and close until the landing pad 2 and the UAV are completely lowered into the protective shell 1, the cover plate 301 is flush with the ground, and the equipment returns to standby mode.
