Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, specifically relating to a foldable UAV emergency take-off and landing site device. Background Technology

[0002] With the rapid development of drone technology, drones are increasingly being used in various fields, such as aerial photography, surveying, rescue, and inspection. In some special scenarios, such as emergency rescue and field operations, temporary take-off and landing sites are needed for drones. However, existing drone take-off and landing sites are usually fixed concrete or metal structures, which cannot be flexibly moved or transported, making it difficult to meet the needs of emergency response and rapid deployment.

[0003] Traditional non-foldable drone landing pads present several problems. First, their large size makes them inconvenient to transport and carry. In situations requiring emergency drone deployment, the landing pad cannot be quickly transported to the designated location, potentially delaying rescue or operational opportunities. Second, the construction cost of such fixed-structure landing pads is high, requiring significant manpower, resources, and time. Moreover, once built, their location is difficult to adjust or change according to actual needs. Furthermore, traditional landing pads are ill-suited for complex terrain or areas with limited space, restricting the scope of drone use.

[0004] Some simple, portable take-off and landing mats, made of lightweight fabric or plastic, are easy to carry and inexpensive. They can solve the problem of drones taking off and landing on uneven ground to some extent, and are suitable for scenarios with relatively simple terrain and low requirements for take-off and landing conditions, such as ordinary outdoor shooting operations. However, these take-off and landing mats have poor stability and are easily blown over or moved in windy conditions, which cannot guarantee the safe take-off and landing of drones. In addition, they usually do not have an optimized design for folding and storage, and take up a lot of space when carried, which is not conducive to long-distance transportation and rapid deployment.

[0005] Complex Foldable Take-Off and Landing Platforms: Some foldable take-off and landing platforms employ complex mechanical structures, such as multi-link mechanisms and sophisticated locking systems. These platforms can achieve a relatively stable unfolded state, providing relatively stable take-off and landing conditions for UAVs, making them suitable for special operations with high stability requirements, such as UAV take-off and landing in military reconnaissance. However, their complex structure and numerous components result in high production costs. The unfolding and folding process requires specialized personnel to follow strict operating procedures, which is time-consuming, and repairs are difficult and costly if any component fails.

[0006] To address this, we propose a foldable emergency take-off and landing site device for unmanned aerial vehicles (UAVs). This device not only requires no complicated operating procedures or professional skills and can be deployed in a short time, but also has a small size and light weight when folded, making it convenient to transport and carry. Utility Model Content

[0007] The purpose of this invention is to provide a foldable emergency take-off and landing site device for unmanned aerial vehicles (UAVs). This device not only requires no complicated operating procedures or professional skills and can be deployed in a short time, but also has a small size and light weight when folded, making it convenient to transport and carry.

[0008] The specific technical solution adopted by this utility model is as follows:

[0009] A foldable UAV emergency take-off and landing site device includes a take-off and landing platform. The take-off and landing platform includes multiple connecting plates. Each connecting plate has a pin on both sides that are rotatably arranged. An elastic tension component is arranged between every two pins to allow the connecting plate to be folded and stored.

[0010] Furthermore, the elastic tensioning assembly includes a hollow arc-shaped plate disposed on one of the pins, a spring disposed inside the hollow arc-shaped plate, a piston plate disposed on one side of the spring, an arc-shaped movable plate disposed on one side of the piston plate, and an end of the arc-shaped movable plate away from the piston plate passing through the hollow arc-shaped plate and connected to the other pin.

[0011] Furthermore, the arc-shaped movable plate is matched with the hollow cavity of the hollow arc-shaped plate.

[0012] Furthermore, the take-off and landing platform is equipped with an anti-slip surface.

[0013] Furthermore, a support rod is provided at the bottom of the lifting platform, and a fixing plate is threaded onto the bottom of the support rod.

[0014] Furthermore, each of the two connecting plates has a plug and a socket on its side that are close to each other, and the plug and the socket are matched.

[0015] The technical effects achieved by this utility model are as follows:

[0016] Initially, the take-off and landing platform is folded, making it compact and easy to transport. Upon arrival at the required site, the operator begins unfolding it. Using the central connecting plate as the center, the connecting plates on both sides are pulled downwards, activating the elastic tensioning components. Then, rotation begins, centered on a pin on one side. Since the connecting plates are connected by pins and elastic tensioning components, this rotation causes adjacent connecting plates to rotate as well, aligning them with the central connecting plate. The remaining connecting plates are then rotated sequentially to lay out the take-off and landing platform. The structure is simple. When the UAV completes its take-off and landing mission and needs to be retracted, the operator pulls a connecting plate, which activates the elastic tensioning components, causing the connecting plate to rotate under another connecting plate, achieving a quick and smooth folding.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: a foldable UAV emergency take-off and landing field device, including a take-off and landing platform 1, the take-off and landing platform 1 including multiple connecting plates 2, each connecting plate 2 has a pin 3 rotatably arranged on both sides, and an elastic tension component is arranged between every two pins 3 to fold and store the connecting plate 2.

[0025] Its working principle is as follows: First, the take-off and landing platform 1 is in a folded state, which is small in size and easy to transport and carry. When it arrives at the site where it is needed, the operator begins to unfold it. Taking the middle connecting plate 2 as the center, the connecting plates 2 on both sides are pulled down, which makes the elastic tension component work. Then, it starts to rotate by taking the pin 3 on one side as the center. Since the connecting plates 2 are connected to the elastic tension component through the pin 3, this rotation will drive the adjacent connecting plate 2 to also start to rotate, so that the connecting plate 2 is flush with the middle connecting plate 2. The remaining connecting plates 2 are repeated in sequence to lay the take-off and landing platform 1. The structure is simple. When the UAV completes the take-off and landing mission and needs to retract the take-off and landing site device, the operator pulls the connecting plate 2. The connecting plate 2 drives the elastic tension component to work, and then the connecting plate 2 rotates to be under another connecting plate 2, realizing quick and smooth folding.

[0026] The elastic tensioning component includes a hollow arc-shaped plate 4 mounted on one of the pins 3. A spring 5 is installed inside the hollow arc-shaped plate 4. A piston plate 6 is mounted on one side of the spring 5. An arc-shaped movable plate 7 is mounted on one side of the piston plate 6. The end of the arc-shaped movable plate 7 away from the piston plate 6 passes through the hollow arc-shaped plate 4 and is connected to the other pin 3.

[0027] When the connecting plate 2 is pulled, the connecting plate 2 drives the arc-shaped movable plate 7 to move through the pin 3 on it. The arc-shaped movable plate 7 drives the piston plate 6 to stretch the spring 5, thereby adjusting the position and realizing the laying and folding storage of the lifting platform 1.

[0028] The curved movable plate 7 is matched with the hollow cavity of the hollow curved plate 4. This arrangement allows the curved movable plate 7 to move inside the hollow curved plate 4 without jamming.

[0029] The take-off and landing platform 1 can be circular or rectangular, which can meet the needs of different drones.

[0030] The take-off and landing platform 1 is equipped with an anti-slip surface, which increases friction and prevents the drone from sliding.

[0031] The lifting platform 1 is equipped with a support rod 8 at the bottom, and a fixing plate 11 is threaded at the bottom of the support rod 8. The lifting platform 1 is supported by the support rod 8. Since the support rod 8 is threadedly connected to the fixing plate 11, different heights can be adjusted to adapt to complex terrains.

[0032] Two connecting plates 2 are respectively provided with a plug rod 9 and a socket 10 on their sides that are close to each other. The plug rod 9 matches the socket 10. This arrangement allows the plug rod 9 to enter the socket 10 for fixing when the connecting plate 2 is laid.

[0033] The working principle of this utility model is as follows: First, the take-off and landing platform 1 is in a folded state, making it compact and easy to transport. Upon arrival at the site where it is needed, the operator begins the unfolding operation. Using the middle connecting plate 2 as the center, the connecting plates 2 on both sides are pulled downwards, thereby activating the elastic tensioning component. Then, the platform begins to rotate, centered on the pin 3 on one side. Since the connecting plates 2 are connected to the elastic tensioning component via the pin 3, this rotation will cause the adjacent connecting plate 2 to also rotate, making this connecting plate 2 flush with the middle connecting plate 2. The remaining connecting plates 2 are then repeated sequentially to lay out the take-off and landing platform 1. The structure is simple. When the UAV completes its take-off and landing mission and needs to retract the take-off and landing device, the operator pulls the connecting plate 2, which activates the elastic tensioning component, causing the connecting plate 2 to rotate under another connecting plate 2, achieving a quick and smooth folding.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
