Description

Technical Field

[0001] This utility model relates to the field of drone landing pad technology, specifically an automatic lifting drone landing pad. Background Technology

[0002] There are various ways for drones to take off and land, including vertical take-off and landing, rail take-off, catapult take-off, and parachute recovery. Among them, vertical take-off and landing drones are widely used due to their flexibility and convenience, especially suitable for environments with limited space. The selection of drone take-off and landing sites must meet the requirements of being far away from high-voltage lines, tall buildings, and densely populated areas to ensure safety. The take-off and landing environment directly affects the safety and stability of drones.

[0003] For example, patent CN117385779A discloses a portable work fence with a drone take-off and landing platform. The structural components include mounting components, adjusting components, and moving components. The mounting components support the entire device, the adjusting components are located on the upper side of the mounting components, and the moving components are located on both sides of the mounting components. The expansion components include unfolding components, pressing components, and telescopic components. The unfolding components are located above the moving components, the pressing components are located inside the moving components, and the telescopic components are located on both sides of the mounting components. Through the coordinated use of the structural components and expansion components, the drone can be quickly unfolded laterally and longitudinally when needed. This reduces the inconvenience of existing fences, which require multiple sets for assembly and use, resulting in bulkiness, slow unfolding speed, and the need to carry a large number of units, making rapid unfolding difficult and affecting the take-off and landing efficiency of drones. When drones take off and land on conventional helipads or the ground, they pose a certain danger to surrounding personnel. Currently, most methods use fences. After the drone has come to a stop, operators can enter the fence to load, unload, and change batteries, and then exit the fence before the drone can take off. However, fences occupy a large area and are difficult to deploy flexibly.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing drone landing pads. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic lifting drone landing pad to solve the problem mentioned in the background art that most of the current methods use fences. After the drone has come to a stop, the operator can enter the fence to perform operations such as loading, unloading and battery swapping. Then the operator needs to leave the fence before the drone can take off. However, the fence method takes up a large area and is difficult to arrange flexibly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic lifting drone landing pad, comprising a landing platform for drone take-off and landing, four sets of multi-stage lifting columns installed below the landing platform, a lower housing fixedly installed at the lower end of the multi-stage lifting columns, and a lifting drive system for driving the multi-stage lifting columns to move longitudinally in the lower housing; a lifting pallet for autonomously receiving and delivering cargo boxes is lifted and connected to the lower housing, and a loading and unloading drawer for pushing cargo boxes in the lifting pallet is also installed on the lower housing.

[0007] Preferably, the landing platform includes a platform fixedly installed at the output end of the multi-stage lifting column, target lights are installed around the platform, and status lights displaying the status of the display device are installed on the surface of the platform; a loading and unloading cargo door is slidably installed on the platform, and positioning components that limit the position of the UAV are symmetrically arranged on both sides of the loading and unloading cargo door on the platform.

[0008] Preferably, the multi-stage lifting column includes a driven pulley rotatably connected to the lower housing, a primary lead screw coaxially connected to the driven pulley, a primary nut threaded onto the primary lead screw, and a sleeve two fixedly installed on the primary nut; a secondary lead screw fixedly connected to the primary nut, the secondary lead screw having a hollow structure, a secondary nut threaded onto the secondary lead screw, and a sleeve three fixedly installed on the secondary nut; sleeve three slidably connected to sleeve two, sleeve two being slidably connected to sleeve one, and sleeve one being fixedly installed on the lower housing.

[0009] Preferably, an outer cylinder is fixedly connected to the secondary nut, and the tops of the outer cylinder and the sleeve are all fixedly connected to the lifting platform via flanges.

[0010] Preferably, a lower limit position for limiting the movement of the first-stage nut is provided on the outer side of the first-stage lead screw near the lower housing, and an upper limit position for limiting the movement of the first-stage nut is provided on the outer side of the first-stage lead screw near the lifting platform.

[0011] Preferably, the lifting drive system includes a drive motor fixedly installed in the lower housing, the output end of the drive motor is connected to a drive pulley, and a synchronous belt is sleeved and connected to the outside of the drive pulley and the driven pulley; multiple tensioning pulleys that constrain the synchronous belt and wrap around the outside of the drive pulley and the driven pulley are also rotatably installed in the lower housing.

[0012] Preferably, an electric push rod is fixedly installed on the lower housing, and the output end of the electric push rod is fixedly connected to the bottom of the lifting tray; a guide shaft is also fixedly connected to the bottom of the lifting tray, and the guide shaft is slidably connected to the lower housing.

[0013] Preferably, a handle is fixedly installed on the loading and unloading drawer, and a guide shaft two is fixedly connected to the bottom of the loading and unloading drawer, with the guide shaft two slidably connected to the lower box body.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the automatic lifting drone landing pad achieves the isolation of the drone from the operator in the height direction during take-off and landing through the lifting landing pad, eliminates the need for fences, occupies less space, and allows for flexible deployment.

[0015] The lifting drive system uses a drive motor and a synchronous belt, along with a tensioning device, to achieve synchronous lifting and lowering of four lifting columns. It occupies little space, is simple to control, and has reliable operation. Furthermore, the primary and secondary lead screws in the lifting columns form a two-stage lead screw mechanism, achieving a large extension ratio. This allows the lifting platform to be lowered to a height that is easy for people to operate, and also raised to a sufficiently safe lifting and lowering height, resulting in a wide range of lifting and lowering adjustments.

[0016] Furthermore, based on drone positioning components, loading and unloading warehouse doors, lifting pallets, and loading and unloading drawers, an automated loading and unloading process can be achieved, eliminating the need for manual loading and unloading of goods on the drone. This highly automated process reduces manual labor. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figures 1-5 The present invention provides the following technical solution: an automatic lifting drone landing pad, comprising a landing platform 1 for drone take-off and landing, four sets of multi-stage lifting columns 2 installed below the landing platform 1, a lower box 5 fixedly installed at the lower end of the multi-stage lifting columns 2, and a lifting drive system 6 for driving the multi-stage lifting columns 2 to move longitudinally in the lower box 5; a lifting pallet 3 for autonomously receiving and delivering boxes is lifted and connected to the lower box 5, and a loading and unloading drawer 4 for pushing the boxes in the lifting pallet 3 is also installed on the lower box 5.

[0025] The landing platform 1 includes a platform 101 fixedly installed at the output end of the multi-stage lifting column 2. Target lights 103 are installed around the platform 101, and status lights 104 for displaying the status of the device are installed on the surface of the platform 101. A loading and unloading cargo door 102 is slidably installed on the platform 101, and positioning components 105 for limiting the position of the UAV are symmetrically arranged on both sides of the loading and unloading cargo door 102 on the platform 101.

[0026] The multi-stage lifting column 2 includes a driven pulley 201 rotatably connected to the lower housing 5. A primary lead screw 202 is coaxially connected to the driven pulley 201. A primary nut 203 is threaded onto the primary lead screw 202. A sleeve 207 is fixedly installed on the primary nut 203. A secondary lead screw 205 is fixedly connected to the primary nut 203. The secondary lead screw 205 has a hollow structure. A secondary nut 204 is threaded onto the secondary lead screw 205. A sleeve 3 206 is fixedly installed on the secondary nut 204. The sleeve 3 206 is slidably connected to the sleeve 207. The sleeve 207 is slidably connected to the sleeve 1 208, and the sleeve 1 208 is fixedly installed on the lower housing 5.

[0027] An outer cylinder 209 is fixedly connected to the secondary nut 204. The tops of the outer cylinder 209 and the sleeve 206 are both fixedly connected to the lifting platform 1 via flanges 210.

[0028] A lower limit position 2021 is provided on the outer side of the first-stage lead screw 202 near the lower housing 5 to limit the movement of the first-stage nut 203, and an upper limit position 2022 is provided on the outer side of the first-stage lead screw 202 near the lifting platform 1 to limit the movement of the first-stage nut 203.

[0029] The lifting drive system 6 includes a drive motor 601 fixedly installed in the lower housing 5. The output end of the drive motor 601 is connected to a drive pulley 602. A synchronous belt 603 is sleeved and connected to the outside of the drive pulley 602 and the driven pulley 201. Multiple tensioning pulleys 604, which are restraining synchronous belts 603 and wrapped around the drive pulley 602 and the driven pulley 201, are also rotatably installed in the lower housing 5.

[0030] The drone takes off and lands on platform 101. During takeoff and landing, the height of platform 101 from the lower housing 5 needs to be adjusted. The height of platform 101 can be adjusted within a wide range through the multi-stage lifting column 2. The drive motor 601 controls the rotation of the active pulley 602. Under the transmission of the synchronous belt 603, the active pulley 602 can drive the driven pulley 201 to rotate. The driven pulley 201 drives the first-stage lead screw 202 to rotate synchronously. Under the threaded transmission between the first-stage lead screw 202 and the first-stage nut 203, the first-stage nut 203, the second-stage lead screw 205, and the second sleeve 207 can be controlled to move upward simultaneously. When the first-stage nut 203 moves to the uppermost position... At this point, the primary nut 203 is in contact with the upper limit switch 2022. Under the limiting action, the primary nut 203 no longer moves upward. At this time, the rotation of the primary screw 202 can drive the secondary screw 205 to rotate synchronously. The secondary screw 205 can control the secondary nut 204 to move upward under the threaded transmission. When the secondary nut 204 moves upward, it drives the sleeve 206, the outer cylinder 209 and the flange 210 to move upward synchronously. Under this part of the power transmission, the platform 101 can be pushed to move upward within a large range, so that the platform 101 moves upward away from the operator and observer, maintaining the safety of the UAV take-off and landing operation. The overall space occupied is small, and flexible arrangement can be achieved.

[0031] Example 2: Based on Example 1, a lifting pallet 3 and a loading / unloading drawer 4 are also disclosed, with the following specific structure: an electric push rod 302 is fixedly installed on the lower box 5, and the output end of the electric push rod 302 is fixedly connected to the bottom of the lifting pallet 3; a guide shaft 301 is also fixedly connected to the bottom of the lifting pallet 3, and the guide shaft 301 is slidably connected to the lower box 5.

[0032] A handle 401 is fixedly installed on the loading and unloading drawer 4, and a guide shaft 402 is fixedly connected to the bottom of the loading and unloading drawer 4. The guide shaft 402 is slidably connected to the lower box 5.

[0033] When loading and unloading cargo with the drone, the platform 101 is lowered and adjusted to the lowest position. The drone is then moved forward between the two sets of positioning components 105, and the loading and unloading cargo door 102 is pushed to move into the interior of the platform 101, so that the bottom of the drone cargo box is in a through state.

[0034] Next, the electric push rod 302 is operated to push the lifting pallet 3 upward. The lifting pallet 3 moves upward and supports the bottom of the cargo box under the drone. The drone is equipped with a corresponding locking mechanism to lock the cargo box. The locking mechanism is an internal structure of the drone and will not be described in detail here. After the locking mechanism is released, the cargo box is placed on the lifting pallet 3. The lifting pallet 3 is controlled to move downward, which moves the cargo box into the loading and unloading drawer 4. The staff pulls the loading and unloading drawer 4 outward along the direction of the guide shaft 402. The loading and unloading drawer 4 can pull the cargo box to the outside so that the staff can take out the items in the cargo box and complete the unloading.

[0035] When loading, place the cargo box on the loading and unloading drawer 4, push the loading and unloading drawer 4 inward, then move the lifting pallet 3 upward, the lifting pallet 3 lifts the cargo box to below the drone, then the lifting pallet 3 moves downward to reset, and then locks the cargo box on the drone. The multi-stage lifting column 2 pushes the platform 101 upward to the highest position, moves and closes the loading and unloading hatch 102, and then the drone can be controlled to take off.
