Description

Technical Field

[0001] This utility model relates to the field of drone take-off and landing pad technology, and in particular to a portable composite wing drone take-off and landing pad. Background Technology

[0002] Compound-wing drones refer to the perfect combination of fixed-wing and rotary-wing drones. Compound-wing drones have the advantages of both types of drones. Fixed-wing drones have the characteristics of high flight speed, high flight altitude and long flight time, while rotary-wing drones have the characteristics of vertical take-off and landing, hovering and flexibility. A landing pad is a device that can be used to facilitate the take-off and landing of drones.

[0003] Chinese patent CN221367564U discloses a helipad, including a foldable landing pad for parking drones. A balancing bracket for adjusting the level of the landing pad is located beneath it. The balancing bracket is detachably connected to the landing pad. Each balancing bracket includes at least three support rods, each support rod comprising at least two rod sections, with adjacent rod sections slidingly connected along their length. The detachable connection between the balancing bracket and the landing pad allows for height adjustment of each support rod by sliding it up and down.

[0004] Regarding the aforementioned technologies, it has been found that the landing pads used for existing drones have fixed landing pad dimensions, which cannot be adjusted according to the size and model of the drone. This makes it inconvenient to carry when using a larger landing pad, while a smaller landing pad results in insufficient stability for larger drones during takeoff and landing. Utility Model Content

[0005] The purpose of this invention is to solve the problems of the prior art and provide a portable compound wing UAV take-off and landing pad.

[0006] The objective of this utility model is achieved through the following technical solution: a portable compound-wing UAV take-off and landing pad, comprising a central base, a tilting frame, and a tray assembly; the tilting frame is evenly arranged with several components along the outer periphery of the central base; the tilting frame is rotatably connected to the outer periphery of the central base; the tray assembly comprises several components and is slidably disposed on the lower surface of the central base; the tray assembly is used to support the tilting frame; a drive disk is installed at the center of the lower surface of the central base; the drive disk is used to adjust the synchronous extension and retraction of all tray assemblies; and telescopic support legs are connected to the bottom of the central base.

[0007] The center seat is designed to serve as the central part of the stop plate. When a large stop plate is not needed, the center seat is sufficient. When a large stop plate is required, the usable area of ​​the center seat can be extended by using a flip frame. The flip frame can be flipped to a horizontal position to form a larger stop plate together with the center seat. When not in use, the flip frame can be flipped down for easy and flexible storage. Several tray assemblies are evenly installed on the lower end of the base plate. When the flip frame is flipped to a horizontal position, the tray assemblies can extend from the lower end of the base plate and support the lower end of the flip frame, ensuring that the flip frame can be used stably in a horizontal position. A drive disc is installed at the center of the lower end of the base plate. When in use, the extension and retraction of the tray assemblies can be adjusted by rotating the drive disc. Several telescopic feet are evenly installed on the lower end of the base plate, ensuring that the equipment can be stably supported on the ground during use.

[0008] The center base includes a base plate and a positioning frame; the positioning frame is evenly distributed on the outer surface of the base plate along its circumference; the positioning frame is fixedly connected to the base plate; the positioning frame is used to rotatably install the flipping frame; a stop mark is provided on the upper surface of the base plate; a ring-shaped light strip is embedded in the base plate.

[0009] The center base is designed with a combination of a base plate and positioning frames. When in use, the base plate ensures stable start-up and stop of the small drone. At the same time, by installing several positioning frames on the base plate, a flip frame can be installed to extend the usable area of ​​the base plate when in use. A stop mark is set in the center of the upper surface of the base plate to help the drone determine its position when landing. The ring light strip is set to facilitate nighttime indication. The base plate can have a built-in battery to power the ring light strip, or it can be powered by an external power source.

[0010] The positioning frame includes a main frame block and connecting side shafts; the connecting side shafts are arranged opposite to each other on both sides of the main frame block; the connecting side shafts are fixedly connected to the main frame block;

[0011] By designing the positioning frame as a structure in which the main frame block and the connecting side shaft cooperate, it can be fixedly installed in the base plate by the main frame block when it is easy to use. The connecting side shafts on both sides of the main frame block make it easier to rotate and install the tilting frame.

[0012] The flipping frame includes a middle frame plate and triangular plates; the triangular plates include two and are arranged opposite each other on both sides of the middle frame plate; the triangular plates are hinged to the two side edges of the middle frame plate by hinges;

[0013] The flip-up frame is designed with a structure that combines a center frame and triangular plates. When in use, the triangular plates on both sides can be flipped to be flush with the center frame. When not in use, the triangular plates on both sides can be flipped to the top of the center frame, making it easy for the center frame to be flipped down for storage. When all the flip-up frames are flipped open around the center base, the center base and the flip-up frames together form a hexagon, which helps to expand the usable size.

[0014] The edge of the middle frame plate near the center seat is arc-shaped; an ear plate extends outward from the arc-shaped edge; the ear plate is rotatably connected to the connecting side shaft; the arc-shaped edge of the middle frame plate facilitates assembly and rotatable connection with the outer periphery of the center seat;

[0015] By installing ear plates on the middle shelf, it is easy to connect the ear plates to the side shaft, ensuring that it can be stably flipped and stored during use.

[0016] The pallet assembly includes a main pallet and a sliding plate; one end of the sliding plate is fixedly connected to the main pallet; a positioning vertical shaft is fixedly installed at the other end of the sliding plate; a guide frame is fixedly installed on the lower surface of the center seat; the sliding plate slides through the guide frame; the positioning vertical shaft drives the sliding plate to translate within the guide frame under the action of the drive disc;

[0017] By designing the pallet assembly into a structure that combines the main pallet and the sliding plate, the main pallet can be slidably mounted on the guide frame via the sliding plate when in use. At the same time, the guide frame acts as a limit to keep the pallet assembly under the center seat from swaying or falling. When support is needed, the main pallet can be pushed out from the bottom of the seat plate, and the center frame can be supported by the main pallet.

[0018] The drive disc includes a disc portion, a vertical plate, and an operating disc; a positioning shaft is provided at the center of the central seat; the disc portion is rotatably mounted on the positioning shaft; a positioning groove that mates with the positioning vertical shaft is provided on the disc portion; the vertical plate is radially spaced at the bottom of the disc portion; the upper end of the vertical plate is fixedly connected to the disc portion; the lower end of the vertical plate is fixedly connected to the operating disc; when the operating disc rotates, it drives the disc portion to rotate, thereby driving the positioning vertical shaft in the positioning groove to translate radially along the central seat.

[0019] By designing the drive plate into a structure that combines a disc, a vertical plate, and an operating panel, the positioning vertical shaft can be installed via the positioning groove on the disc when it is easy to use. Once the positioning vertical shaft is installed in the positioning groove, the operator only needs to rotate the disc to adjust the position of the positioning vertical shaft. The vertical plate and operating panel are designed to facilitate better rotation operation for the operator.

[0020] A further technical solution is that the telescopic support leg includes a foot plate, a sliding tube, and a movable rod; the sliding tube is fixedly installed on the foot plate; the movable rod is slidably installed inside the sliding tube; a locking bolt is installed on the side of the sliding tube; an internally threaded tube is provided at the bottom of the center seat; and a screw that mates with the internally threaded tube is provided at the head of the movable rod.

[0021] By designing the telescopic outriggers with a structure consisting of a foot plate, a sliding tube, and a movable rod, the foot plate provides support for use on the ground. The sliding tube allows for the sliding installation of the movable rod, which can be adjusted to change the operating height. Once the height is adjusted, the movable rod can be locked by turning the locking bolt to ensure stable use of the telescopic outriggers. A screw is installed at the head of the movable rod, which can be connected to an internally threaded tube for easy installation and disassembly.

[0022] The working process of this utility model is as follows: When the equipment is not in use, the triangular plates on both sides of the middle frame plate are flipped to the upper end of the middle frame plate. Then, the drive disk is rotated clockwise to move all the tray sets into the storage slots at the lower end of the base plate. This allows the middle frame plate to be flipped downwards for storage, and all the telescopic legs can be disassembled, making the equipment easy to carry. When needed, the telescopic legs are installed in the internal threaded tube at the lower end of the center base to ensure stable use of the base plate. When the drone is small, it can be used directly as a landing board. When the drone is large, all the middle frame plates are flipped to a horizontal position, and then the drive disk is rotated counterclockwise to extend all the main trays from the lower end of the base plate. The support plates then support the middle frame plate. Finally, the triangular plates on both sides of the middle frame plate are flipped down for stable use.

[0023] This utility model has the following advantages: when in use, the area for parking drones can be increased by using several flip frames, which can easily meet the needs of drones of different sizes. Moreover, when the flip frame is flipped to a horizontal position, it can be supported by a tray group, which facilitates the stable use of the flip frame. The setting of the drive disk allows the operator to control the extension and retraction of all tray groups at the same time, which has the advantages of convenient operation and applicability to the take-off and landing of drones of different sizes.

[0039] Example 1: As Figure 1 , 2 As shown in Figure 3, a portable compound-wing UAV take-off and landing pad includes a central base 1, a flip frame 2, and a tray assembly 3. Several flip frames 2 are evenly arranged along the outer periphery of the central base 1. The flip frames 2 are rotatably connected to the outer periphery of the central base 1. The tray assembly 3 includes several trays slidably disposed on the lower surface of the central base 1. The tray assembly 3 supports the flip frame 2. A drive disk 4 is installed at the center of the lower surface of the central base 1. The drive disk 4 is used to adjust the synchronous extension and retraction of all tray assemblies 3. Telescopic support legs 5 are connected to the bottom of the central base 1.

[0040] The center seat 1 is designed to serve as the central part of the stop plate. When a large stop plate is not needed, the center seat 1 is sufficient. When a large stop plate is required, the usable area of ​​the center seat 1 can be extended by using the flip frame 2. The flip frame 2 can be flipped to a horizontal position to form a larger stop plate together with the center seat 1. When not in use, the flip frame 2 can be flipped down for easy and flexible storage. Several tray assemblies 3 are evenly installed on the lower end of the base plate 11. When the flip frame 2 is flipped to a horizontal position, the tray assemblies 3 can extend from the lower end of the base plate 11 and support the lower end of the flip frame 2, ensuring that the flip frame 2 can be used stably in a horizontal position. A drive disc 4 is installed at the center of the lower end of the base plate 11. When in use, the extension and retraction of the tray assemblies 3 can be adjusted by rotating the drive disc 4. Several telescopic support legs 5 are evenly installed on the lower end of the base plate 11. When in use, the equipment can be stably supported on the ground by the telescopic support legs 5.

[0041] like Figure 4 , 5 As shown, the center seat 1 includes a base plate 11 and a positioning frame 12; the positioning frame 12 is evenly arranged on the outer surface of the base plate 11 along the circumference; the positioning frame 12 is fixedly connected to the base plate 11; the positioning frame 12 is used to rotatably install the flipping frame 2; a stop mark 111 is provided on the upper surface of the base plate 11; a ring light strip 112 is embedded in the base plate 11.

[0042] The center base 1 is configured as a structure in which the base plate 11 and the positioning frame 12 cooperate. When easy to use, the base plate 11 can ensure that the small drone can start and stop stably. At the same time, by installing several positioning frames 12 on the base plate 11, the flip frame 2 can be installed through the positioning frame 12 when easy to use, so that the usable area of ​​the base plate 11 can be extended through the flip frame 2 when in use. A stop mark 111 is set in the center of the upper surface of the base plate 11 to help the drone to better determine its position when landing. At the same time, the ring light strip 112 is set to facilitate the use of nighttime indication. The base plate 11 can have a built-in battery to power the ring light strip 112, or it can be powered by an external power source.

[0043] like Figure 5 As shown, the positioning frame 12 includes a main frame block 121 and a connecting side shaft 122; the connecting side shaft 122 is arranged opposite to each other on both sides of the main frame block 121; the connecting side shaft 122 is fixedly connected to the main frame block 121.

[0044] By designing the positioning frame 12 into a structure in which the main frame block 121 and the connecting side shaft 122 cooperate, it can be fixedly installed in the base plate 11 through the main frame block 121 when it is easy to use. By setting the connecting side shaft 122 on both sides of the main frame block 121, the flip frame 2 can be rotated and installed more conveniently.

[0045] like Figure 7 As shown, the flipping frame 2 includes a middle frame plate 21 and triangular plates 22; the triangular plates 22 include two and are arranged opposite each other on both sides of the middle frame plate 21; the triangular plates 22 are hinged to the two side edges of the middle frame plate 21 by hinges 23.

[0046] The flip-up frame 2 is designed with a structure in which the middle frame plate 21 and the triangular plate 22 cooperate. When it is easy to use, the triangular plates 22 on both sides can be flipped to be flush with the middle frame plate 21. When not in use, the triangular plates 22 on both sides can be flipped to the upper surface of the middle frame plate 21, which makes it easy for the middle frame plate 21 to be flipped down for storage. When all the flip-up frames 2 are flipped open around the center seat 1, the center seat 1 and the flip-up frame 2 together form a hexagon, which is beneficial to expanding the usable size.

[0047] like Figure 7 As shown, the edge of the middle frame plate 21 near the center seat 1 is an arc-shaped edge; an ear plate 211 extends outward from the arc-shaped edge; the ear plate 211 is rotatably connected to the connecting side shaft 122; the arc-shaped edge of the middle frame plate 21 facilitates assembly and rotatable connection with the outer periphery of the center seat 1;

[0048] By providing ear plates 211 on the middle frame plate 21, it is convenient to cooperate with the connecting side shaft 122 through the ear plates 211, ensuring that it can be stably flipped and stored during use.

[0049] like Figure 3 , 6 As shown, the pallet assembly 3 includes a main pallet 31 and a sliding plate 32; one end of the sliding plate 32 is fixedly connected to the main pallet 31; a positioning vertical shaft 321 is fixedly installed at the other end of the sliding plate 32; a guide frame 114 is fixedly installed on the lower surface of the center seat 1; the sliding plate 32 slides through the guide frame 114; the positioning vertical shaft 321 drives the sliding plate 32 to translate within the guide frame 114 under the action of the drive disc 4;

[0050] By designing the pallet assembly 3 as a structure in which the main pallet 31 and the sliding plate 32 cooperate, when it is easy to use, the main pallet 31 can be slidably installed in the guide frame 114 through the sliding plate 32. At the same time, the guide frame 114 plays a limiting role, confining the pallet assembly 3 to the center seat 1 and preventing it from swinging or falling. When support is needed, the main pallet 31 can be pushed out from the lower end of the seat plate 11, and the center frame plate 21 can be supported by the main pallet 31.

[0051] like Figure 3 , 8 As shown, the drive disk 4 includes a disc portion 41, a vertical plate 42, and an operation disk 43; a positioning shaft is provided at the center of the central seat 1; the disc portion 41 is rotatably mounted on the positioning shaft; a positioning groove 411 that cooperates with the positioning vertical shaft 321 is provided on the disc portion 41; the vertical plate 42 is radially spaced at the bottom of the disc portion 41; the upper end of the vertical plate 42 is fixedly connected to the disc portion 41; the lower end of the vertical plate 42 is fixedly connected to the operation disk 43; when the operation disk 43 rotates, it drives the disc portion 41 to rotate, which in turn drives the positioning vertical shaft 321 in the positioning groove 411 to translate radially along the central seat 1.

[0052] By designing the drive disc 4 into a structure in which the disc part 41, the vertical plate 42 and the operation disc 43 cooperate, the positioning vertical shaft 321 can be installed through the positioning groove 411 on the disc part 41 when it is easy to use. After the positioning vertical shaft 321 is installed in the positioning groove 411, the operator only needs to rotate the disc part 41 to adjust the position of the positioning vertical shaft 321. The setting of the vertical plate 42 and the operation disc 43 makes it easier for the operator to perform rotation operation.

[0053] like Figure 1 , 2 As shown, the telescopic support leg 5 includes a foot plate 51, a sliding tube 52, and a movable rod 53; the sliding tube 52 is fixedly installed on the foot plate 51; the movable rod 53 is slidably installed inside the sliding tube 52; a locking bolt 521 is installed on the side of the sliding tube 52; an internally threaded tube 113 is provided at the bottom of the center seat 1; and a screw 531 that mates with the internally threaded tube 113 is provided at the head of the movable rod 53.

[0054] By designing the telescopic outrigger 5 as a structure consisting of a foot plate 51, a sliding tube 52, and a movable rod 53, it can be used easily by supporting the outrigger on the ground using the foot plate 51. The movable rod 53 is slidably installed through the sliding tube 52, allowing the movable rod 53 to be adjusted in height for convenient use. After adjusting the height, the movable rod 53 can be locked by rotating the locking bolt 521 to ensure the stable use of the telescopic outrigger 5. A screw 531 is provided at the head of the movable rod 53, which can be connected to the internally threaded tube 113 for convenient use. The threaded connection ensures easy installation and disassembly of the equipment.

[0055] In this embodiment, when the device is not in use, the triangular plates 22 on both sides of the middle frame plate 21 are flipped to the upper surface of the middle frame plate 21, and then the drive disk 4 is rotated clockwise. The drive disk 4 is used to retract all the tray assemblies 3 into the lower surface of the base plate 11, so that the middle frame plate 21 can be flipped downwards for storage, and all the telescopic legs 5 can be disassembled, making the device easy to carry. When it is needed, the telescopic legs 5 are installed in the internal threaded tube 113 on the lower surface of the center seat 1, so that the base plate 11 can be used stably. When the drone is small, it can be used directly as a landing board through the base plate 11. When the drone is large, all the middle frame plates 21 can be flipped to a horizontal position, and then the drive disk 4 is rotated counterclockwise. The drive disk 4 is used to extend all the main trays 31 from the lower surface of the base plate 11, and then the support plates can be used to support the middle frame plate 21. Finally, the triangular plates 22 on both sides of the middle frame plate 21 can be flipped down for stable use.
