Description
Technical Field
[0001] This utility model relates to the field of drone nesting technology, and in particular to a drone autonomous charging nest. Background Technology
[0002] Unmanned aerial vehicles, or UAVs for short, are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously by an onboard computer, either completely or intermittently. UAVs are usually equipped with a nest, which allows them to be placed in the nest when not in use.
[0003] A search revealed a public (announcement) document (CN217260703U) disclosing an autonomous charging dock for unmanned aerial vehicles (UAVs). The dock includes a main body with a first opening on its upper surface. An opening / closing mechanism is provided at the first opening. A landing pad is located within the main body, and a centering mechanism is provided on the landing pad to adjust the UAV's position to the center of the landing pad. Four first motors are located at the four corners of the lower surface of the main body, below the landing pad. Each first motor has a screw at its output end, with the upper end of the screw penetrating the lower surface of the landing pad and extending to the inner top surface of the main body. The screw is connected to the inner top surface of the main body via a first bearing. This invention features a simple structure, convenient operation, adjustable landing pad height for easy UAV parking, and the ability to dissipate heat and clean dust from the UAV.
[0004] While the above solutions can adjust the height of the landing pad inside the drone nest to facilitate drone parking and can also dissipate heat and clean dust from the drone, they cannot conveniently adjust the position of the charging interface according to different drone models. Therefore, we propose a drone autonomous charging nest. Utility Model Content
[0005] The main purpose of this utility model is to provide an autonomous charging station for drones, which solves the problem of not being able to conveniently adjust the position of the charging interface according to different drone models by setting up a lifting unit and a charging unit.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An autonomous charging station for unmanned aerial vehicles (UAVs) includes a main unit, a lifting unit and a charging unit disposed inside the main unit, a centering unit disposed on the side of the lifting unit, and an adjustment unit disposed on the surface of the main unit.
[0008] The lifting unit includes a fixed seat installed on the bottom wall of the main unit, a first threaded shaft movably disposed inside the fixed seat and having two sections of opposite threads, a movable seat installed on the circumferential side of the first threaded shaft, a parking platform disposed inside the main unit, a transmission component disposed between the movable seat and the parking platform, and a first drive motor installed at the input end of the first threaded shaft.
[0009] The charging unit includes a hydraulic telescopic cylinder installed on the bottom wall of the main unit, a U-shaped seat installed on the telescopic end of the hydraulic telescopic cylinder, a second threaded shaft movably disposed inside the U-shaped seat, a movable part installed on the circumferential side of the second threaded shaft, a charging interface installed on the side wall of the movable part, and a second drive motor installed on the input end of the second threaded shaft.
[0010] Preferably, the main unit includes a nest body, a cover movably mounted on top of the nest body, and locking casters mounted on the bottom of the nest body.
[0011] Preferably, the transmission component includes a first connecting seat mounted on the top of the mobile seat, a second connecting seat mounted on the bottom of the landing pad, and a transmission rod with one end movably connected to the first connecting seat and the other end movably connected to the second connecting seat.
[0012] Preferably, the centering unit includes a movable slot formed on the side wall of the helipad, a third threaded shaft movably disposed inside the movable slot and having two sections of oppositely oriented threads, a third drive motor installed at the input end of the third threaded shaft, and a centering component disposed on the third threaded shaft.
[0013] Preferably, the centering component includes a first movable block mounted on the circumferential side of the third threaded shaft, and an L-shaped centering rod mounted on the side wall of the first movable block.
[0014] Preferably, the adjustment unit includes a fixed groove formed in the side wall of the helipad, a threaded rod movably disposed in the fixed groove, a second movable block installed on the periphery of the threaded rod, a push rod installed on the side wall of the second movable block, a fourth drive motor installed at the input end of the threaded rod, and an adjustment component disposed on the surface of the helipad.
[0015] Preferably, the adjusting component includes a connecting plate installed on the side wall opposite to the landing pad and the fixed groove, an electric telescopic rod installed on the inner side wall of the connecting plate, and a push plate installed on the telescopic end of the electric telescopic rod.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] In this invention, through the installation of a lifting unit and a charging unit, when the drone needs to be centered and parked, the lid is opened, and after the drone is placed on the landing pad, the third drive motor drives the third threaded shaft to rotate. Because the third threaded shaft has two sections of threads with opposite directions of rotation, the two first moving blocks can drive the L-shaped centering rods to move closer to each other along the third threaded shaft until the sidewalls of the two L-shaped centering rods are in contact with the drone's parking frame. Then, when the fourth drive motor drives the threaded rod to rotate, the second moving block can push the drone to move on the landing pad via a push rod, thus achieving the centering and parking of the drone. When different models need to be centered and parked... When adjusting the position of the charging port on the drone, the first drive motor drives the first threaded shaft to rotate. Since the first threaded shaft has two sections of threads with opposite directions, the two moving seats can move along the first threaded shaft in a direction that is closer to or farther from each other. This drives the landing pad to move up and down through the transmission components until the charging port and the drone's charging port are at the same height and then stop. Subsequently, when the second drive motor drives the second threaded shaft to rotate, the moving components can drive the charging port to move along the second threaded shaft until the charging port and the drone's charging port are aligned and then stop. This allows for the adjustment of the charging port position according to different drone models. Attached Figure Description

[0048] When the position of the charging interface needs to be adjusted according to different models of drones, the first drive motor 204 drives the first threaded shaft 203 to rotate. Since the first threaded shaft 203 has two threads with opposite directions, the two moving seats 202 can move along the first threaded shaft 203 in a direction that is closer to or farther from each other. This drives the landing pad 205 to move up and down through the transmission component 206 until the charging interface 304 is at the same height as the drone's charging port and then stops.
