Description

A drone take-off and landing platform Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) take-off and landing platforms, and more particularly to a UAV take-off and landing platform. Background Technology

[0002] A drone takeoff and landing platform is a flight platform that serves as the operating system for drones. It provides a protective habitat against harsh weather conditions, theft, and wild animals. It also provides power and charging, data transmission, and storage functions, enabling basic operations such as automatic takeoff, landing, and storage. When not in operation, the drone remains in standby mode within the platform. When needed, the platform's hatch opens, and the drone automatically flies out and follows a pre-planned route to perform its tasks. After completing its mission, the drone autonomously lands within the platform area.

[0003] The traditional flip-top takeoff and landing platform for drones involves the top cover flipping at a 90-degree angle to both sides of the housing. This does not change the takeoff and landing area of ​​the platform. To maximize the takeoff and landing area, the platform is typically made quite large, resulting in a bulky platform. However, the internal structure of the platform does not require much space, leading to significant space waste. Therefore, this application proposes a different drone takeoff and landing platform. Summary of the Invention

[0004] The purpose of this invention is to provide a drone take-off and landing platform to solve the problem of the large size of current drone take-off and landing platforms.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A drone take-off and landing platform, the platform comprising:

[0007] The cabin, with a landing platform installed at its upper end;

[0008] The machine cover is provided in two parts. When the two machine covers are closed, the upper end face of the machine cover is parallel to the landing platform.

[0009] Each of the engine hoods is provided with at least one swing arm assembly for connecting to the engine compartment. The swing arm assembly includes an engine hood swing arm and follower pulleys and fixed pulleys located at both ends of the engine hood swing arm. The two ends of the engine hood swing arm are respectively rotatably connected to the engine compartment and the engine hood. The follower pulleys are fixedly connected to the engine hood, and the fixed pulleys are fixedly connected to the engine compartment. Synchronous belts are fitted on the follower pulleys and the fixed pulleys. The axes of the follower pulleys and the fixed pulleys are respectively coincident with the rotation centers of the engine hood swing arm on the engine compartment and the engine hood. A power mechanism is provided inside the engine compartment to drive the engine hood swing arm to rotate on the engine compartment.

[0010] Furthermore, the swing arm assembly also includes:

[0011] A pressure roller is connected to the machine cover swing arm via a pressure arm. The pressure roller is rotatably connected to one end of the pressure arm, and the end of the pressure arm away from the pressure roller is rotatably connected to the machine cover swing arm, so that an elastic structure is provided between the pressure arm and the machine cover swing arm to drive the pressure roller to press against the timing belt.

[0012] Furthermore, multiple clamping wheels and clamping arms are provided.

[0013] Furthermore, the swing arm assembly also includes:

[0014] The stop bar is U-shaped and is fixedly connected to the machine cover swing arm by bolts. The timing belt is located inside the stop bar.

[0015] Furthermore, a visual QR code is provided at the center of the landing platform.

[0016] Furthermore, the lifting platform is also equipped with a pressure block and quick-release bolts. The pressure block is arched, and both ends of the pressure block are fixedly connected to the lifting platform by quick-release bolts.

[0017] Furthermore, a swing shaft is provided at one end of the fuselage swing arm that connects to the nacelle. The swing shaft is fixedly connected to the fuselage swing arm, and the swing shaft is rotatably connected to the nacelle. The take-off and landing platform also includes:

[0018] A limiting component that limits the extreme positions of the rotation of the rocker shaft.

[0019] Furthermore, the limiting component includes:

[0020] A limiting arm, which is fixedly connected to the swing shaft;

[0021] A contact bolt, which is fixedly connected to the limiting arm;

[0022] A limit switch is fixedly connected inside the engine room. When the rocker shaft rotates to its limit position, the contact bolt contacts the limit switch. The limit switch is electrically connected to the control mechanism inside the engine room.

[0023] Furthermore, the limiting component also includes:

[0024] A limiting plate, which is fixed to the cabin.

[0025] A limiting bolt is connected to the limiting plate via a threaded structure. When the rocker shaft rotates to its limit position, the limiting arm contacts the limiting bolt.

[0026] In summary, the present invention has the following advantages compared with the prior art:

[0027] The UAV take-off and landing platform disclosed in this embodiment of the utility model achieves the opening and closing of the hood by rotating the swing arm assembly with a near-parallelogram structure to drive the hood to rotate around the cabin. When the hood rotates, the upper surface of the hood is always parallel to the platform, so that rotating the hood to a preset position can expand the area of ​​the platform, increase the take-off and landing area, and reduce the volume of the take-off and landing platform.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0037] As shown in Figures 1 and 2, one embodiment of this utility model provides a drone take-off and landing platform, the take-off and landing platform comprising:

[0038] The cabin 10 has a landing platform 40 at its upper end;

[0039] The machine cover 20 is provided in two forms. When the two machine covers 20 are closed, the upper end face of the machine cover 20 is parallel to the lifting platform 40.

[0040] A swing arm assembly 30 is provided for each of the engine hoods 20 to connect to the engine compartment 10. The swing arm assembly 30 includes an engine hood swing arm 31 and follower pulleys 32 and fixed pulleys 33 located at both ends of the engine hood swing arm 31. The two ends of the engine hood swing arm 31 are rotatably connected to the engine compartment 10 and the engine hood 20, respectively. The follower pulleys 32 are fixedly connected to the engine hood 20, and the fixed pulleys 33 are fixedly connected to the engine compartment 10. Synchronous belts 34 are sleeved on the follower pulleys 32 and the fixed pulleys 33. The axes of the follower pulleys 32 and the fixed pulleys 33 coincide with the rotation centers of the engine hood swing arm 31 on the engine compartment 10 and the engine hood 20, respectively. A power mechanism is provided inside the engine compartment 10 to drive the engine hood swing arm 31 to rotate on the engine compartment 10.

[0041] In this embodiment, the cabin 10 and the shroud 20 are structures of existing flip-type UAV take-off and landing platforms. When taking off and landing a UAV using the take-off and landing platform disclosed in this embodiment, the control mechanism located in the cabin 10 controls the power mechanism to work. The power mechanism controls the shroud swing arm 31 to rotate on the cabin 10. When the shroud swing arm 31 rotates, it drives the shroud 20 to open outward, and the two shrouds 20 move away from each other. At the same time, the shroud 20 rotates around the cabin 10 under the drive of the shroud swing arm 31. Since the fixed pulley 33 is fixedly connected to the cabin 10 and the follower pulley 32 is fixedly connected to the shroud 20, the follower pulley... The wheel 32, the fixed pulley 33, and the synchronous belt 34 form a stable parallelogram structure. When the housing 20 rotates with the housing swing arm 31, the synchronous belt 34 controls the follower pulley 32 to rotate in the opposite direction, so that the housing 20 always maintains the same posture when rotating, that is, the upper surface of the housing 20 is always parallel to the lifting platform 40. When the housing swing arm 31 rotates at a preset angle, the upper surface of the housing 20 is flush with the lifting platform 40. At this time, the upper surface of the housing 20 can serve as a temporary platform, that is, the housing 20 can increase the lifting area of ​​the lifting platform 40, thereby reducing the area of ​​the lifting platform 40 during the manufacturing stage, that is, reducing the overall volume.

[0042] The UAV take-off and landing platform disclosed in this embodiment of the utility model achieves the opening and closing of the shroud 20 by rotating the swing arm assembly 30 with a parallelogram-like structure to drive the shroud 20 to rotate around the cabin 10. When the shroud 20 rotates, the upper surface of the shroud 20 is always parallel to the take-off and landing platform 40, so that when the shroud 20 rotates to a preset position, the area of ​​the take-off and landing platform 40 can be expanded, increasing the take-off and landing area and reducing the volume of the take-off and landing platform.

[0043] Specifically, in this embodiment, the cabin 10 is existing technology. For example, the cabin 10 includes a box 11 and a base 12. The base 12 is located at the bottom of the box 11. The box 11 is equipped with the control mechanism of an existing UAV take-off and landing platform, such as a control chip, signal transceiver structure, remote sensing structure, etc. The take-off and landing platform 40 is fixedly connected to the upper surface of the box 11 by screws.

[0044] Preferably, the enclosure 11 is also provided with an inspection door 13, which facilitates the user to inspect and maintain the equipment inside the enclosure 11.

[0045] As a preferred embodiment of this invention, as shown in Figure 5, a filter assembly 60 is also provided inside the housing 11 to filter the air and moisture entering the housing 11. In this embodiment, a heat dissipation structure is provided inside the housing 11. The heat dissipation is existing technology, such as a cooling fan, used to draw in outside air to dissipate heat from the electronic equipment inside the housing 11. An air inlet is provided on the housing 11. The filter assembly 60 includes a salt spray filter 61 and louvers 62. The louvers 62 are fixedly connected to the air inlet. The salt spray filter 61 is fixedly connected to the inside of the housing 11 and is located at the air inlet. The salt spray filter 61 is existing technology and is used to filter outside air.

[0046] The cover 20 is existing technology. For example, the cover 20 is a square box with openings on two adjacent sides. The side of the cover 20 with openings is the side facing each other and the side that fits against the landing platform 40. When the two covers 20 are closed, the two covers 20 cover the landing platform 40. When the two covers 20 are open, the upper surface of the cover 20 is located on both sides of the landing platform 40.

[0047] In this embodiment, the hood swing arm 31 is an oblong rod. The end of the hood swing arm 31 is hinged to the housing 11 and the hood 20 via a pin. The follower pulley 32 and the fixed pulley 33 are respectively rotatably connected to the pin structures at both ends of the hood swing arm 31. If a swing shaft 38 is provided at the end of the hood swing arm 31 connected to the housing 11, the swing shaft 38 is fixedly connected to the hood swing arm 31 and rotatably connected to the housing 11. The swing shaft 38 is connected to the output end of the power mechanism inside the housing 11. If the power mechanism inside the housing 11 is a servo motor, the swing shaft 38 is connected to the upper output shaft of the servo motor to achieve the purpose of the servo motor driving the swing shaft 38 to rotate.

[0048] In a preferred embodiment of this invention, the swing arm assembly 30 further includes:

[0049] A pressure roller 35 is connected to the machine cover swing arm 31 via a pressure arm 36. The pressure roller 35 is rotatably connected to one end of the pressure arm 36, and the end of the pressure arm 36 away from the pressure roller 35 is rotatably connected to the machine cover swing arm 31 via a spiral spring. This allows the pressure arm 36 to drive the pressure roller 35 to press against the synchronous belt 34, thereby enabling the pressure roller 35 to tension the synchronous belt 34. In other structures of this embodiment, the spiral spring can be replaced with a tension spring. In this case, the two ends of the tension spring are fixed to the pressure arm 36 and the machine cover swing arm 31, respectively. The tension spring presses the pressure roller 35 against the synchronous belt 34 by tightening the pressure arm 36.

[0050] In this embodiment, multiple clamping rollers 35 and clamping arms 36 are provided.

[0051] In a preferred embodiment of this invention, the swing arm assembly 30 further includes:

[0052] The stop bar 37 is U-shaped and is fixedly connected to the machine cover swing arm 31 by bolts. The timing belt 34 is located inside the stop bar 37. The stop bar 37 serves to protect the timing belt 34. Multiple stop bars 37 are provided.

[0053] The lifting platform 40 is a flat plate structure in the prior art, and the lifting platform 40 is fixedly connected to the housing 11 by bolts.

[0054] Preferably, as shown in Figure 6, a visual QR code 43 is provided at the center of the take-off and landing platform 40. After the UAV takes off autonomously from the take-off and landing platform 40 and completes its mission, during the process of the UAV landing on the take-off and landing platform 40, the visual device carried by the UAV captures and locates the visual QR code 43, and lands accurately on the take-off and landing platform 40.

[0055] As a preferred embodiment of this invention, as shown in Figures 1 and 3, the landing platform 40 is also provided with a pressure block 41 and a quick-release bolt 42. The pressure block 41 is arched, and both ends of the pressure block 41 are fixedly connected to the landing platform 40 by the quick-release bolt 42. The pressure block 41 and the quick-release bolt 42 serve to quickly fix or disassemble the drone. When fixing the drone, the pressure block 41 presses on the support feet of the drone.

[0056] As a preferred embodiment of this invention, as shown in Figure 4, the take-off and landing platform further includes:

[0057] The limiting component 50 limits the extreme position of the rotation of the rocker shaft 38 to protect the hood 20 and the cabin 10. After the hood 20 is opened and closed to the designated position, the power is automatically cut off to control the power mechanism to stop working, which not only accurately completes the designated action but also prevents the power mechanism from being overloaded and burned out.

[0058] Specifically, in this embodiment, a fixing plate 14 is fixed inside the housing 11 by bolts. The limiting component 50 includes a limiting arm 51, a contact bolt 55, and a limiting switch 56. The limiting arm 51 is fixedly connected to the rocker shaft 38, and the limiting arm 51 is fixedly connected to both sides of the rocker shaft 38. The contact bolt 55 is fixedly connected to the limiting arm 51. The limiting component 50 is fixedly connected to the fixing plate 14. When the rocker shaft 38 rotates to its limit position, such as the closed position or the open position of the cover 20, the contact bolt 55 touches the limiting switch 56. The limiting switch 56 is electrically connected to the control mechanism inside the housing 11. The limiting switch 56 sends an electrical signal to the control mechanism, and the control mechanism cuts off the power to the power mechanism. The limiting arm 51 is a square plate, and the limiting arm 51 is clamped on the rocker shaft 38 by bolts, so that when the rocker shaft 38 rotates, the rocker shaft 38 drives the limiting arm 51 to rotate.

[0059] Preferably, the limiting component 50 further includes a limiting plate 52 and a limiting bolt 54. The limiting plate 52 is fixed to the housing 11 by a mounting plate 53. The limiting plate 52 and the mounting plate 53 are an integral structure. The limiting bolt 54 is connected to the limiting plate 52 by a threaded structure. When the rocker shaft 38 rotates to the limit position, the limiting arm 51 contacts the limiting bolt 54, thereby achieving physical isolation.

[0060] In this embodiment, the limit switch 56 can also be a normally closed micro switch. The limit switch 56 is connected to the power supply line of the power mechanism. When the contact bolt 55 touches the limit switch 56, the limit switch 56 disconnects the power supply line of the power mechanism.

[0061] Preferably, the machine cover 20 is provided with anti-collision mechanisms at the open and closed positions to protect and buffer the equipment. The anti-collision mechanism is a rubber block, which is located on one side of the machine cover 20 facing each other.
