Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) take-off and landing technology, specifically to an outdoor take-off and landing platform for UAVs. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and onboard program control devices, or operated autonomously, either fully or intermittently, by an onboard computer. Compared to manned aircraft, UAVs are often better suited for tasks that are too "dull, dirty, or dangerous." UAVs can be categorized into military and civilian applications. In the military field, UAVs are divided into reconnaissance aircraft and target drones. In the civilian field, the combination of UAVs with industry applications represents the true necessity of UAVs. Applications in aerial photography, agriculture, plant protection, miniature selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying, news reporting, power line inspection, disaster relief, film and television shooting, and creating romantic moments have greatly expanded the uses of UAVs. Developed countries are also actively expanding industry applications and developing UAV technology. The rapid development of UAV-related technologies both domestically and internationally has resulted in a wide variety of UAV systems with diverse applications and distinct characteristics, leading to significant differences in size, weight, range, flight time, flight altitude, flight speed, and mission objectives. According to the configuration of the flight platform, drones can be classified into fixed-wing drones, rotary-wing drones, unmanned airships, paragliding drones, flapping-wing drones, etc.

[0003] Patent announcement CN 211810298 U discloses a drone field take-off and landing platform, including a take-off and landing platform. A folding device is bolted to the bottom of the platform, and a first support rod is bolted to the bottom of the folding device. The outer wall of the first support rod has a track groove, and a telescopic rod is engaged inside the first support rod. A soil-inserting base is fixedly connected to the bottom of the telescopic rod, and a locking rod is welded to the top outer wall of the telescopic rod. A locking head is threaded onto the outer wall of the locking rod, and a folding lock is internally connected to the folding device. When the drone needs to be used in the field, the first support rod is pulled up perpendicular to the folding device, and the folding lock is rotated to lock the first support rod. Simultaneously, the soil-inserting base is inserted into mud, grassland, desert, etc. When the ground is uneven, the locking rod is pulled to extend the telescopic rod, leveling the take-off and landing platform. After use, the folding lock is rotated to fold the first support rod for easy carrying.

[0004] The applicant believes that the following drawbacks exist: the drone's field take-off and landing platform does not have a cushioning function. Because the drone will generate impact force during landing, it is easy for the drone to be damaged due to excessive impact force, which is not conducive to protecting the drone and the take-off and landing platform and has defects. Summary of the Invention

[0005] The purpose of this invention is to provide a field take-off and landing platform for unmanned aerial vehicles (UAVs) to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a field take-off and landing platform for unmanned aerial vehicles (UAVs), comprising a mounting plate, a support mechanism at the bottom of the mounting plate, a buffer mechanism at the top of the mounting plate, a second fixing plate at the top of the buffer mechanism, a lifting mechanism at the top of the second fixing plate, and the UAV body at the top of the lifting mechanism.

[0007] The buffer mechanism includes four fixed rods, each fixedly connected to one of the four corners of the top of the mounting plate. A first fixed plate is fixedly connected to the top of each of the two fixed rods. A fixed frame is fixedly connected to the middle of the first fixed plate, and the fixed frame is fixedly connected to both sides of the top of the mounting plate. A first spring is sleeved on both sides of the surface of each fixed rod. A second support member is slidably connected to the middle of the surface of each fixed rod. Two first springs are located at the top and bottom of the second support member. Two second support members are symmetrically arranged on both sides of the top of the mounting plate, and the second support members are fixedly connected to the bottom of the second fixed plate.

[0008] Preferably, the second support member has a first support member fixedly connected to both sides, and a first support rod is rotatably connected inside the first support member. A support arm is fixedly connected to the surface of the first support rod. The support arm provides support for the sliding rod, ensuring that the sliding rod can achieve its support and buffering functions.

[0009] Preferably, a second support rod is rotatably connected to the side of the support arm away from the first support member. A sliding rod is fixedly connected to the surface of the second support rod, and a second spring is sleeved on the surface of the sliding rod. The second spring is located on one side of the support arm. Under the elastic potential energy of the first spring and the second spring, the impact force generated by the UAV downward can be effectively buffered, avoiding the phenomenon that the UAV impact force is too large and causes damage to the take-off and landing platform.

[0010] Preferably, a support plate is slidably connected to the surface of the sliding rod, and the support plate is fixedly connected to the top of the mounting plate. Several support plates are provided, and the several support plates are arranged at equal intervals. The sliding plate can be supported by the provided support plates.

The number of threaded rods is four, and each of the four threaded rods is threadedly connected to a support seat. A drone is mounted on the top of each support seat. During the rotation of the threaded rods, the support seats can be driven to move up and down, thereby realizing the lifting and lowering of the take-off and landing platform.

[0012] Preferably, each threaded rod has a worm wheel fixedly connected to its bottom, and a worm is meshed on the surface of the worm wheel. There are two worms, and the two worm wheels are symmetrically arranged on both sides of the support base. A pulley set is driven to connect the surfaces of the two worm wheels. A motor is fixedly connected to the middle of the surface of one of the worms. With the cooperation of the worm and the worm wheel, the threaded rod can be driven to rotate synchronously.

[0013] Preferably, a horizontal plate is rotatably connected to the top of the threaded rod, a connecting plate is fixedly connected to the bottom of the horizontal plate, the connecting plate is fixedly connected to the top of the second fixed plate, and connecting parts are rotatably connected to both sides of the worm gear surface. The connecting parts are fixedly connected to the surface of the second support member, and the support seat is disposed on the top of the second support member. The horizontal plate provides support for the threaded rod, preventing the threaded rod from shaking during rotation.

[0014] Preferably, the support mechanism includes support legs, each of which is fixedly connected to both sides of the bottom of the mounting plate. A placement plate is fixedly connected to the bottom of each support leg. The number of placement plates is four, and the four placement plates are arranged symmetrically. The support legs on both sides can be reinforced by the reinforcement rods and reinforcement plates.

[0015] Preferably, a reinforcing plate is fixedly connected to the top of the support leg, and vertical plates are fixedly connected to both sides of the bottom of the reinforcing plate. The vertical plates are fixedly connected to the top of the placement plate. Two vertical plates are provided, and a reinforcing rod is fixedly connected between the two vertical plates.

[0017] 1. This field take-off and landing platform for drones, through its buffer mechanism, can effectively buffer the downward impact force generated by the drone under the elastic potential energy of the first and second springs, avoiding damage to the take-off and landing platform caused by excessive impact force from the drone, and thus protecting both the drone and the take-off and landing platform.

[0018] 2. This field take-off and landing platform for UAVs, through its lifting mechanism, can drive the support base to move up and down during the rotation of the threaded rod, thereby raising and lowering the take-off and landing platform. It can adjust the flight altitude of the UAV according to the terrain, thus improving the practicality of the device.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] This invention provides a technical solution:

[0029] Example 1:

[0030] Combination Figures 1 to 2 -3, an outdoor take-off and landing platform for unmanned aerial vehicles (UAVs), including a mounting plate 1, a support mechanism 4 at the bottom of the mounting plate 1, a buffer mechanism 2 at the top of the mounting plate 1, a second fixing plate 5 at the top of the buffer mechanism 2, a lifting mechanism 3 at the top of the second fixing plate 5, and the UAV body at the top of the lifting mechanism 3.

[0031] The buffer mechanism 2 includes fixed rods 26, which are fixedly connected to the four corners of the top of the mounting plate 1. There are four fixed rods 26. The top of each of the two fixed rods 26 is fixedly connected to a first fixed plate 21. A fixed frame 25 is fixedly connected to the middle of the first fixed plate 21. The fixed frame 25 is fixedly connected to both sides of the top of the mounting plate 1. A first spring 22 is sleeved on both sides of the surface of the fixed rod 26. A second support member 24 is slidably connected to the middle of the surface of the fixed rod 26. Two first springs 22 are set at the top and bottom of the second support member 24. There are two second support members 24. The two second support members 24 are symmetrically arranged on both sides of the top of the mounting plate 1. The second support members 24 are fixedly connected to the bottom of the second fixed plate 5.

[0032] Furthermore, the second support member 24 is fixedly connected to the first support member 23 on both sides. The first support member 23 is rotatably connected to the first support rod 27. The surface of the first support rod 27 is fixedly connected to the support arm 29. The support arm 29 is provided to support the sliding rod 202, ensuring that the sliding rod 202 can realize its own support and buffer functions.

[0033] Furthermore, a second support rod 28 is rotatably connected to the side of the support arm 29 away from the first support member 23. A sliding rod 202 is fixedly connected to the surface of the second support rod 28, and a second spring 201 is sleeved on the surface of the sliding rod 202. The second spring 201 is located on one side of the support arm 29. Under the elastic potential energy of the first spring 22 and the second spring 201, it can effectively buffer the downward impact force generated by the UAV, and avoid the phenomenon that the UAV impact force is too large and causes damage to the take-off and landing platform.

[0034] Furthermore, a support plate 203 is slidably connected to the surface of the sliding rod 202. The support plate 203 is fixedly connected to the top of the mounting plate 1. Several support plates 203 are provided, and the several support plates 203 are arranged at equal intervals. The sliding plate can be supported by the provided support plates 203.

[0035] Example 2:

[0036] See Figure 4 Furthermore, based on Embodiment 1, the lifting mechanism 3 is further provided, which includes threaded rods 39. Each threaded rod 39 is rotatably connected to the four corners of the second fixed plate 5. There are four threaded rods 39, and each of the four threaded rods 39 is threadedly connected to a support seat 33. The top of the support seat 33 is provided with a drone. During the rotation of the threaded rods 39, the support seat 33 can be driven to move up and down, thereby realizing the lifting and lowering of the take-off and landing platform.

[0037] Furthermore, each threaded rod 39 is fixedly connected to a worm wheel 31 at its bottom. A worm 32 meshes with the surface of the worm wheel 31. There are two worms 32. The two worm wheels 31 are symmetrically arranged on both sides of the support base 33. A pulley group 38 is driven to the surface of the two worm wheels 31. A motor 36 is fixedly connected to the middle of the surface of one of the worms 32. With the cooperation of the worm 32 and the worm wheel 31, the threaded rod 39 can be driven to rotate synchronously.

[0038] Furthermore, a horizontal plate 35 is rotatably connected to the top of the threaded rod 39, and a connecting plate 34 is fixedly connected to the bottom of the horizontal plate 35. The connecting plate 34 is fixedly connected to the top of the second fixed plate 5. Connecting pieces 37 are rotatably connected to both sides of the surface of the worm gear 32. The connecting pieces 37 are fixedly connected to the surface of the second support member 24. The support seat 33 is set on the top of the second support member 24. The horizontal plate 35 provides support for the threaded rod 39, preventing the threaded rod 39 from shaking during rotation. It can adjust the flight altitude of the UAV according to the terrain, thus improving the practicality of the device.

[0039] Example 3:

[0040] See Figure 5 Furthermore, based on Embodiment 1 and Embodiment 2, the support mechanism 4 further includes support legs 45, each of which is fixedly connected to both sides of the bottom of the mounting plate 1. Each support leg 45 is fixedly connected to a placement plate 41, and four placement plates 41 are provided. The four placement plates 41 are arranged symmetrically. The support legs 45 on both sides can be reinforced by the reinforcing rods 44 and the reinforcing plates 43.

[0041] Furthermore, a reinforcing plate 43 is fixedly connected to the top of the support leg 45, and vertical plates 42 are fixedly connected to both sides of the bottom of the reinforcing plate 43. The vertical plates 42 are fixedly connected to the top of the placement plate 41. There are two vertical plates 42, and a reinforcing rod 44 is fixedly connected between the two vertical plates 42. Through the support leg 45, the lifting platform can be stably supported, ensuring the stability of the lifting platform.

[0042] In actual operation, when the drone lands on the support base 33, the impact force generated by the drone drives the second support member 24 to slide downwards on the surface of the fixed rod 26. At this time, the first spring 22 at the bottom is compressed, and the sliding rod 202 slides inside the support plate 203, compressing the second spring 201. Under the elastic potential energy of the first spring 22 and the second spring 201, the downward impact force generated by the drone can be effectively buffered, preventing damage to the take-off and landing platform caused by excessive impact force. This protects both the drone and the take-off and landing platform. When the height of the take-off and landing platform needs to be adjusted, it can be done by starting the electric... The motor 36 drives the worm gear 32 and worm wheel 31 on one side to rotate synchronously. Under the linkage of the pulley group 38, it can drive the worm gear 32 and worm wheel 31 on both sides to rotate synchronously. At this time, the four threaded rods 39 rotate synchronously. During the rotation of the threaded rods 39, they can drive the support base 33 to move up and down, thereby realizing the lifting and lowering of the take-off and landing platform. It can adjust the flight altitude of the UAV according to the terrain, which improves the practicality of the device. The reinforcing rods 44 and reinforcing plates 43 can reinforce the support legs 45 on both sides. The support legs 45 can provide stable support for the take-off and landing platform and ensure its stability.
