Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV flight platform and a compatible UAV. Background Technology

[0002] With the rapid development of drone technology, drones have been widely used in various fields such as agricultural plant protection, power line inspection, logistics distribution, and surveying and exploration. In actual operation, the flight time of drones is often limited by battery capacity, usually only able to maintain continuous flight for 20 to 40 minutes. Therefore, in long-term, large-scale operation scenarios, it is necessary to frequently land, change batteries, and take off again to ensure the continuity of operations.

[0003] Currently, most drone flight platforms on the market are single-layer flat-panel structures. Such platforms can only accommodate one drone for takeoff, landing, or maintenance operations at a time. When multiple drones are working together, operators must wait for the previous drone to complete battery swapping and other operations and take off before the next drone can land on the same platform, which limits the battery swapping efficiency and overall task throughput of continuous multi-drone operations. Existing platforms use simple blocks or fences to position drones, but the clamping force is insufficient. During battery swapping, drones are prone to displacement due to their own vibration, wind disturbance, uneven ground, and other external factors. Therefore, a drone flight platform and its compatible drones are proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a drone flight platform and a drone adapted thereto, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a drone flight platform, including a support platform, with support frames fixed on both sides of the top of the support platform, a second plate fixed in the middle of the support frame, and a first plate and a third plate respectively provided on the upper and lower sides of the second plate; The first plate, the second plate, and the third plate are each fixed with two bases on their tops, and the tops of the bases are provided with receiving cavities. A transmission assembly is provided on one side of the support frame, and the transmission assembly is used to control the extension and retraction states of the first plate and the third plate. Limiting components are provided on the top of the first plate, the second plate, and the third plate; The transmission assembly includes two sets of synchronous pulleys, with two pulleys in each set. A synchronous belt is wound around the outside of the two synchronous pulleys, and a first sliding frame and a second sliding frame are respectively fixed to the outside of the synchronous belt. The limiting component includes a fixing frame, a sliding groove is provided on the inner side of the fixing frame, a sliding plate is slidably connected to the inner side of the sliding groove, a fixing rod is fixed to one side of the sliding plate, a connecting plate is fixed to one side of the fixing rod, and a pressure plate is fixed to the top of the connecting plate.

[0006] Preferably, the support frame has connecting grooves on both sides, the synchronous pulley is located inside the connecting groove, and the synchronous pulley is rotatably connected to the inside of the support frame through a rotating shaft.

[0007] Preferably, two guide rods are fixed on each side of the inner wall of the support frame, and the number of guide rods is four. The first sliding frame and the second sliding frame are slidably connected to the outside of the guide rods.

[0008] Preferably, the first sliding bracket is fixed to both sides of the third plate, and the second sliding bracket is fixed to both sides of the first plate.

[0009] Preferably, the connecting plate extends through the bottom side of the base, and the pressure plate is located at the top of the base.

[0010] Preferably, the slide plate has a pull rod that rotates via a bearing on the side away from the fixed rod, one end of the pull rod is fixed with a limit rod, and the fixing frame is fixed to the top of the first plate, the second plate, and the third plate.

[0011] Preferably, a spring is sleeved on the outside of the pull rod, and the two ends of the spring are respectively connected to the inner wall of the slide groove and one side of the slide plate, and a vent hole is opened on one side of the slide plate.

[0012] Preferably, a limiting frame is fixed to one side of the fixing frame, and a limiting groove is formed on one side of the limiting frame; When the limiting rod is inside the limiting groove, the pressure plate moves away from the top of the base; when the limiting rod moves away from the inside of the limiting groove, the pressure plate moves to the top of the base.

[0013] Preferably, the support platform has a storage cavity on its inner side, a baffle is hinged to one side of the support platform, support rods are fixed at the four corners of the bottom of the support platform, and casters are installed at the bottom of the support rods.

[0014] An unmanned aerial vehicle (UAV) includes a UAV flight platform, wherein the UAV and a receiving cavity are adapted together.

[0015] Compared with the prior art, the present invention, employing the above technical solution, has the following technical effects: By pulling the third plate outward, the first sliding frame can be driven to slide synchronously along the guide rod under the transmission action of the synchronous belt and two sets of synchronous pulleys. This, in turn, drives the second sliding frame located on top of the synchronous pulley to extend the first plate synchronously in the opposite direction. This allows the first and third plates to unfold to both sides simultaneously relative to the fixed second plate. The operation steps are simple and the actions are smooth. The unfolding of the three-layer parking platform can be completed with one hand. After unfolding, a three-layer staggered parking platform is formed with the second plate as the middle fixed layer and the first and third plates as the upper and lower layers. There is vertical spacing between each layer, which can accommodate the base of multiple drones at the same time. This greatly increases the effective load-bearing width of the entire platform, solves the pain point of traditional single-layer platforms that can only replace batteries one by one and cannot operate multiple drones in parallel, and significantly improves the battery swapping efficiency in multi-drone collaborative operation scenarios.

[0016] The limit assembly employs a spring-driven automatic clamping mechanism. In its initial state, the compressed spring moves the pressure plate via a slide plate, fixed rod, and connecting plate, causing the pressure plate to press firmly against the drone's feet and cooperate with the base to form a reliable clamp. This achieves locking after the drone lands, effectively preventing displacement of the drone during battery swapping due to external interference such as vibration and wind. By pulling the lever, the limit rod can be pulled to one side of the limit frame, causing the slide plate to compress the spring and move the pressure plate, releasing the clamp on the feet. A single person can unlock the drone within seconds, improving the drone's turnaround efficiency and meeting the needs of rapid and continuous multi-flight operations. Attached Figure Description

[0022] Example 1

[0023] Please see Figure 1-7 This invention provides a technical solution: a drone flight platform, including a support platform 1, with support frames 5 fixed on both sides of the top of the support platform 1, a second flat plate 7 fixed in the middle of the support frame 5, and a first flat plate 6 and a third flat plate 8 respectively provided on the upper and lower sides of the second flat plate 7; a storage cavity is provided inside the support platform 1, and a baffle 4 is hinged to one side of the support platform 1. After opening the baffle 4, a spare battery for the drone can be placed inside the storage cavity for convenient and quick battery replacement on site. Support rods 2 are fixed at the four corners of the bottom of the support platform 1, and universal wheels 21 are installed at the bottom of the support rods 2. The universal wheels 21 have a self-locking structure, which can be used to flexibly move the entire flight platform to the designated position for drone take-off and landing. After reaching the designated position, the self-locking structure of the universal wheels 21 is locked to make the flight platform stop stably.

[0024] The first plate 6, the second plate 7, and the third plate 8 are fixed with two bases 10 on their tops, and the top of each base 10 has a receiving cavity 11. A transmission component 3 is provided on one side of the support frame 5. The transmission component 3 is used to control the extension and retraction state of the first plate 6 and the third plate 8. The tops of the first plate 6, the second plate 7, and the third plate 8 are all provided with limiting components 9. The bottoms of the first plate 6, the second plate 7, and the third plate 8 are all fixed with reinforcing frames. The reinforcing frames are all fixed to the first sliding frame 33 and the second sliding frame 35 to increase the stability of the first plate 6 and the third plate 8 after they are extended.

[0025] The transmission assembly 3 includes two sets of synchronous pulleys 31, with two pulleys in each set. A synchronous belt 32 is wound around the outside of the two synchronous pulleys 31, and a first sliding frame 33 and a second sliding frame 35 are fixed to the outside of the synchronous belt 32 respectively. When only one UAV needs to land and replace the spare battery, the flight platform is in the initial retracted state, that is, the first plate 6 is located on the top of the support frame 5, and the third plate 8 is also retracted to one side of the support frame 5. At this time, the synchronous pulleys 31 installed inside the connecting grooves 36 on both sides of the support frame 5 are in a standby state. The synchronous pulleys 31 are rotatably connected to the inside of the support frame 5 through the rotating shaft. The support frame 5 has connecting grooves 36 on both sides. Synchronous pulleys 31 are located inside the connecting grooves 36 and are rotatably connected to the inside of the support frame 5 via a rotating shaft. Two guide rods 34 are fixed to each side of the inner wall of the support frame 5. The guide rods 34 are preferably made of metal, and there are four guide rods 34. A first sliding frame 33 and a second sliding frame 35 are slidably connected to the outside of the guide rods 34. Preferably, the first sliding frame 33 and the second sliding frame 35 slide on the outside of the guide rods 34 via linear bearings. The first sliding frame 33 is fixed to both sides of the third plate 8, and the second sliding frame 35 is fixed to both sides of the first plate 6. On the side, first sliding frames 33 are fixed on both sides of the third plate 8. When the third plate 8 is pulled outward, the first sliding frames 33 slide outward synchronously. When the first sliding frames 33 slide outward, they drive the synchronous belt 32 to move. Due to the transmission characteristics of the synchronous belt 32, when the bottom first sliding frame 33 moves outward, the synchronous belt 32 drives the top synchronous wheel 31 to rotate. The synchronous wheel 31 rotates inside the support frame 5 through a rotating shaft. The other end of the synchronous belt 32 drives the second sliding frame 35 to move in the opposite direction. When the second sliding frame 35 moves outward, the first plate 6 extends outward synchronously to the other side. After being unfolded into place, the first plate 6 and the third plate 8 are connected and fixed to the support platform 1 respectively by bolts. The support platform 1 has a screw hole on one side (not shown in the figure) to prevent the first plate 6 and the third plate 8 from retracting during use and to ensure the stability of the platform. After the fixing is released, the first plate 6 is retracted by pushing the third plate 8 in the opposite direction.

[0026] The limiting component 9 includes a fixing frame 91. A sliding groove is provided on the inner side of the fixing frame 91. A sliding plate 96 is slidably connected to the inner side of the sliding groove. A fixing rod 98 is fixed to one side of the sliding plate 96. A connecting plate 92 is fixed to one side of the fixing rod 98. A pressure plate 93 is fixed to the top of the connecting plate 92. The connecting plate 92 movably passes through the bottom side of the base 10. The pressure plate 93 is located at the top of the base 10. A pull rod 94 is rotatably connected to the side of the sliding plate 96 away from the fixing rod 98 via a bearing. A limiting rod 95 is fixed to one end of the pull rod 94. The fixing frame 91 is fixed to the top of the first plate 6, the second plate 7, and the third plate 8. Pulling the limiting rod 95 causes the limiting rod 95 to disengage from the inner side of the limiting groove 910.

[0027] A spring 97 is sleeved on the outside of the pull rod 94. The two ends of the spring 97 are respectively connected to the inner wall of the slide groove and one side of the slide plate 96. A vent is provided on one side of the slide plate 96. The vent can prevent air resistance in the slide groove and ensure smooth operation. A limit frame 99 is fixed on one side of the fixed frame 91. A limit groove 910 is provided on one side of the limit frame 99. When the limiting rod 95 is inside the limiting groove 910, the pressure plate 93 moves away from the top of the base 10. When the limiting rod 95 moves away from the inside of the limiting groove 910, the pressure plate 93 moves to the top of the base 10. Rotate the limiting rod 95 to make it re-engage inside the limiting groove 910. During this process, the pull rod 94 rotates around the bearing, and the spring 97 sleeved on the outside of the pull rod 94 is compressed. The two ends of the spring 97 are respectively connected to the inner wall of the slide groove and one side of the slide plate 96. The compression and energy storage of the spring 97 causes the slide plate 96 to slide away from the fixed rod 98 inside the slide groove. The sliding of the slide plate 96 causes the fixed rod 98 to move, the fixed rod 98 causes the connecting plate 92 to move to one side, and the connecting plate 92 causes the pressure plate 93 to detach from the top of the base 10. At this time, the pressure plate 93 leaves the top of the base 10, and the drone's feet are no longer subject to the pressure of the pressure plate 93. The drone takes off and completes the operation.

[0028] Working principle or structural principle: The platform is moved to the take-off / landing position of the drone by using the universal wheels 21 at the four corners of the bottom of the support platform 1, and locked in place by the self-locking structure of the universal wheels 21. The baffle 4 can be opened to take out the spare battery of the drone from the storage cavity inside the support platform 1 and prepare for replacement.

[0029] When only one drone needs a battery replacement, the first plate 6 can remain in the retracted state at the top of the support frame 5. When multiple drones need battery replacements simultaneously, first loosen the locking bolts between the third plate 8 and the support frame 5, then pull the third plate 8 outward. The first sliding frames 33 fixed on both sides of the third plate 8 slide along the guide rod 34. Since the first sliding frames 33 are fixed on the lower side of the synchronous belt 32 and located at the bottom of the synchronous pulley 31, under the transmission of the synchronous belt 32 and the two sets of synchronous pulleys 31, the second sliding frame 35 located at the top of the synchronous pulley 31 drives the first plate 6 to move synchronously in the opposite direction. This causes the first plate 6 and the third plate 8 to extend to both sides relative to the fixed second plate 7, forming a three-layer staggered parking platform. After extending into place, the first plate 6, the third plate 8, and the support platform 1 are locked again with bolts to prevent accidental retraction. Through the linkage of the above-mentioned transmission components 3, the third plate 8 and the first plate 6 extend to both sides simultaneously, while the second plate 7 remains stationary as an intermediate fixed part. This greatly increases the effective load-bearing width of the entire platform, allowing it to accommodate the base 10 of multiple drones simultaneously.

[0030] When the drone lands, its feet are guided by the inclined surface of the inner wall of the receiving cavity 11 and fall accurately into the receiving cavity 11 of the base 10. In the initial state, the limiting rod 95 in the limiting assembly 9 is not engaged in the limiting groove 910. The compressed spring 97 pushes the sliding plate 96 to move along the inner sliding groove of the fixing frame 91. Then, through the fixing rod 98 and the connecting plate 92, the pressure plate 93 is driven to press down, so that the pressure plate 93 is located on the top of the base 10 and presses the drone feet tightly. It works with the base 10 to achieve reliable clamping of the feet and keep the drone stable when changing batteries. When the drone needs to be released for takeoff, pull lever 94 to pull limit lever 95 to one side of limit frame 99. At this time, slide plate 96 compresses spring 97 and slides. At the same time, through fixed lever 98 and connecting plate 92, pressure plate 93 moves away from the top of base 10, releasing the clamp on the drone feet. Then rotate lever 94 to make limit lever 95 engage inside limit groove 910. The spring 97 is kept in a compressed state by the constraint of limit groove 910, and pressure plate 93 is kept in the raised position. At this time, the drone can take off smoothly. When the next drone needs to be fixed, simply rotate limit lever 95 out of limit groove 910, spring 97 resets and pushes pressure plate 93 to press again.

[0031] Example 2

[0032] The present invention also provides a drone that is adapted to the receiving cavity 11. When the drone lands, its feet first contact the inclined surface at the entrance of the receiving cavity 11. Under the guidance of the inclined surface, the feet automatically slide down the inclined surface and finally land accurately in the predetermined position inside the receiving cavity 11. The inclined surface guide reduces the difficulty of drone landing. Even in the case of slight wind disturbance, the drone feet can slide smoothly into the receiving cavity 11 under the guidance of the inclined surface, which improves the success rate and efficiency of landing.

[0033] After the drone feet fall into the receiving cavity 11, the pressure plate 93 of the limiting component 9 presses the drone feet from above, and the base 10 supports the drone feet from below, forming a two-way clamping and fixing, ensuring that the drone is stable on the platform and does not shift, providing stable working conditions for battery replacement operations.

[0034] In summary, by pulling the third plate 8 outward, the first sliding frame 33 can be driven to slide synchronously along the guide rod 34 under the transmission action of the synchronous belt 32 and the two sets of synchronous pulleys 31. This, in turn, drives the second sliding frame 35 located on top of the synchronous pulley 31 to extend the first plate 6 synchronously in the opposite direction. This achieves the simultaneous unfolding of the first plate 6 and the third plate 8 relative to the fixed second plate 7 to both sides. The operation steps are simple and the actions are smooth. The unfolding of the three-layer parking platform can be completed with one hand. After unfolding, a three-layer staggered parking platform is formed with the second plate 7 as the middle fixed layer and the first plate 6 and the third plate 8 as the upper and lower layers. There is a vertical spacing between each layer, which can accommodate the base 10 of multiple drones at the same time. This greatly increases the effective load-bearing width of the entire platform, solves the pain point of traditional single-layer platforms that can only replace batteries one by one and cannot operate multiple drones in parallel, and significantly improves the battery swapping efficiency in multi-drone collaborative operation scenarios.

[0035] The automatic clamping mechanism driven by spring 97, via the limiting component 9, initially compresses the spring 97, which moves the pressure plate 93 through the slide plate 96, fixing rod 98, and connecting plate 92. This causes the pressure plate 93 to press the drone's feet together with the base 10 to form a reliable clamp, thus locking the drone after landing and effectively preventing displacement of the drone during battery swapping due to external interference such as vibration and wind. Pulling the lever 94 will move the limiting rod 95 to one side of the limiting frame 99, causing the slide plate 96 to compress the spring 97 and move the pressure plate 93, releasing the clamp on the feet. A single person can unlock the drone within seconds, improving the drone's turnaround efficiency and meeting the needs of rapid and continuous multi-flight operations.
