Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an automatic lifting and landing platform for unmanned aerial vehicles. Background Art

[0002] Unmanned aerial vehicles, also known as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices, or are operated completely or intermittently autonomously by on-board computers.

[0003] However, in the prior art, existing civilian drones are usually taken out of the carrying box and placed on the ground for takeoff. However, during the takeoff process, the ground needs to be relatively flat or free of interference from debris to take off. However, some ground is rugged or muddy, which makes it impossible for the drone to take off normally. To address the above problems, we have launched an automatic lifting and landing platform for drones. Utility Model Content

[0004] The utility model discloses an automatic lifting and landing platform for unmanned aerial vehicles, which aims to solve the technical problem that a civilian unmanned aerial vehicle is usually taken out of a carrying box and placed on the ground for take-off, but during the take-off process, the ground needs to be relatively flat or free of interference from debris to be able to take off, but some parts of the ground are rugged or muddy, so that the unmanned aerial vehicle cannot take off normally.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The cam is an angular channel that is formed on a pair of cylindrical rollers that are attached to the top of the platform and on the bottom of the platform, wherein the cylindrical rollers are connected to the top of the platform and the cylindrical rollers are connected to the bottom of the platform.

[0007] Through the setting, the carrying box can be placed on the ground, so that the drone can take off directly from above the platform, so that it can take off on rugged ground or muddy roads. When the drone lands above the platform, the first bidirectional screw is rotated to drive the first threaded block to move relative to each other, thereby driving the clamping block to clamp the drone in the center. The second bidirectional screw is driven to move the second threaded block, so that it drives the clamping rod to clamp the drone laterally in the center, thereby stably fixing the drone on the top of the platform.

[0008] In a preferred embodiment, two second slide grooves are provided at the bottom of the inner wall of the carrying box, and the inside of the second slide grooves are rotatably connected to the third bidirectional screws, the outer sides of the third bidirectional screws are threadedly connected to two third threaded blocks, the tops of the third threaded blocks are rotatably connected to connecting rods, and the ends of the connecting rods away from the third threaded blocks are rotatably connected to the platform, and the threads of the third bidirectional screws are opposite.

[0009] Through the arrangement, the third bidirectional screw is rotated to drive the third threaded block to move relative to each other, so that its connecting rod can lift the platform, so that the unmanned vehicle can be lifted for take-off.

[0010] In a preferred solution, a limiting plate is fixedly connected to the bottom of the inner wall of the carrying box and is located between the third threaded blocks. A groove is opened at the bottom of the inner wall of the carrying box and is located below the limiting plate. A fixed block is fixedly connected to the inside of the groove. A rotating shaft is rotatably connected to the outer side of the fixed block. Fourth bevel gears are fixedly connected to both ends of the rotating shaft. Third bevel gears are fixedly connected to the outer sides of the third bidirectional screw rods. The fourth bevel gears are meshingly connected to the corresponding third bevel gears.

[0011] By setting, the rotation of the rotating shaft drives the fourth bevel gear to rotate, thereby driving the third bevel gear to rotate. Since the threads of the third bidirectional screw are opposite, the third bevel gear drives the third bidirectional screw to rotate synchronously.

[0012] In a preferred solution, a fifth bevel gear is fixedly connected to the outer side of the first bidirectional screw, a sixth bevel gear is rotatably connected to the bottom of the inner wall of the first slide groove, the sixth bevel gear is meshingly connected to the fifth bevel gear, a second servo motor is fixedly connected to the bottom of the platform, and an output shaft of the second servo motor is fixedly connected to the sixth bevel gear.

[0013] Through the arrangement, the second servo motor works to drive the sixth bevel gear to rotate and then drives the fifth bevel gear to rotate the first bidirectional screw.

[0014] In a preferred solution, a fixing plate is fixedly connected to the inside of one of the empty slots, a first bevel gear is fixedly connected to the outside of the second bidirectional screw, a second bevel gear is rotatably connected to one side of the fixing plate, the second bevel gear is meshingly connected to the first bevel gear, a first servo motor is fixedly connected to the outside of the fixing plate, and an output shaft of the first servo motor is fixedly connected to the second bevel gear.

[0015] Through the arrangement, the first servo motor drives the second bevel gear to rotate, and during the rotation of the second bevel gear, the first bevel gear can be driven to rotate the second bidirectional screw.

[0016] In a preferred solution, a third servo motor is fixedly connected to the outside of the carrying box, the output shaft of the third servo motor is fixedly connected to one of the third bidirectional screws, rubber blocks are fixedly connected to the four corners of the inner wall of the carrying box and located above the platform, and a drone is placed on the top of the platform.

[0017] Through the setting, the movement of the platform can be restricted by the rubber block, and the third bidirectional screw can be mobilized to rotate through the operation of the third servo motor.

[0018] The utility model provides an automatic lifting and landing platform for unmanned aerial vehicles, which has the following advantages:

[0019] First, the carrying box can be placed on the ground, so that the drone can take off directly from the top of the platform, so that it can take off on rugged ground or muddy roads. When the drone lands on the top of the platform, the first double-direction screw is rotated to drive the first threaded block to move relative to each other, thereby driving the clamping block to clamp the drone in the center, and the second double-direction screw is rotated to drive the second threaded block to move, so that it drives the clamping rod to clamp the drone in the center laterally, thereby stably fixing the drone on the top of the platform;

[0020] Secondly, by rotating the third bidirectional screw, the third threaded block is driven to move relative to each other, so that its connecting rod can lift the platform, so that it can lift the unmanned vehicle for take-off. By rotating the rotating shaft, the fourth bevel gear is driven to rotate, thereby driving the third bevel gear to rotate. Since the threads of the third bidirectional screw are opposite, the third bevel gear drives the third bidirectional screw to rotate synchronously. Through the operation of the second servo motor, the sixth bevel gear is driven to rotate, and then the fifth bevel gear is driven to rotate to rotate the first bidirectional screw.
