[0002] With the increasing maturity of drone technology, its flexibility, efficiency, low cost, and adaptability to complex environments have led to its widespread application in fields such as agriculture, engineering surveying, logistics, construction, energy, and public safety. Since drones are primarily used for outdoor operations, such as engineering surveying, the field environment is relatively harsh and complex, making it difficult to find flat, stable sites suitable for drone takeoff and landing. Furthermore, the surrounding areas of these sites are often obstructed by weeds and other debris, posing safety hazards and hindering surveying operations. Existing drone landing platforms either lack height adjustment mechanisms, making them less adaptable to complex terrain, difficult to maintain level, and susceptible to the influence of surrounding debris; or, while some do have height adjustment mechanisms, their overall structure is complex, making them difficult to install, carry, and move. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a foldable all-terrain drone landing pad, which has a simple structure and is easy to use. It not only improves the safety and practicality of the landing pad but is also applicable to different terrain conditions, making it more widely applicable.

[0004] The technical solution adopted by this utility model is: a foldable all-terrain UAV landing pad, including two platform plates and telescopic legs connected by hinges; the platform plates can be assembled to form a flat landing platform, and the top surface of the landing platform is provided with a landing mark; the bottom surface of the platform plates is provided with grooves around its perimeter, and the grooves enclose to form a storage groove; the telescopic legs are rotatably connected to the bottom surface of the platform plates, and their length is adjustable and can be folded and stored in the storage groove; the grooves near the connection of the platform plates are movably connected with locking buckles for locking the two grooves when the landing platform is unfolded.

[0005] Furthermore, the platform plate is hinged by a hinge, and the top surface of the platform plate is provided with a mounting groove that matches the hinge.

[0006] Furthermore, a connecting sleeve is provided at the end of the bottom surface of the platform plate away from the locking buckle.

[0009] Furthermore, the expansion joint includes several nestable pipe sections, and the ends of the expansion joint have a pointed structure.

[0010] Furthermore, the expansion joint also includes a fastening sleeve, the two ends of which are threadedly connected to the two pipe sections respectively; among the adjacent pipe sections, the inner diameter of the pipe section closer to the platform plate is larger than the outer diameter of the other pipe section.

[0011] Furthermore, at least one of the pipe sections has a contraction port at one end away from the platform plate, and the inner side of the connection end between the fastening sleeve and the contraction port has an internal thread that gradually contracts from the outside to the inside.

[0012] Furthermore, the locking buckle includes a fastener and a locking member; the fastener is slidably connected to a groove provided on the groove edge, and has a locking space for accommodating the two groove edges; the locking member is threadedly connected to the fastener and is used to adjust the size of the locking space to lock the two groove edges.

[0027] The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0028] like Figures 1 to 2As shown in the figure, this utility model embodiment proposes a foldable all-terrain UAV landing pad, including two platform plates 1 hinged together and telescopic legs 2; the platform plates 1 can be assembled to form a flat landing platform, and the top surface of the landing platform is provided with a landing mark 3; the bottom surface of the platform plate 1 is provided with groove edges 11 around its perimeter, and the groove edges 11 enclose to form a storage groove; the telescopic legs 2 are rotatably connected to the bottom surface of the platform plate 1, and their length is adjustable and can be folded and stored in the storage groove; a locking buckle 4 is movably connected to the groove edges 11 near the connection of the platform plates 1, which is used to lock the two groove edges 11 when the landing platform is unfolded.

[0029] In this embodiment, by setting telescopic outriggers 2, the height of the platform plate 1 above the ground can be adjusted, eliminating the adverse effects of surrounding weeds and other debris on the take-off and landing of the drone. Simultaneously, multiple telescopic outriggers 2 are used, and their telescopic function allows for adjustment of the length of different outriggers 2 according to complex terrain conditions, ensuring that the levelness of the landing platform meets the drone's take-off and landing requirements. Furthermore, the telescopic outriggers 2 can be folded and stored in the storage slot at the bottom of the platform plate 1, reducing the space occupied by the landing pad, making it easier to carry and move, and less susceptible to damage from bumps. When the landing platform is unfolded, the two corresponding slot edges 11 at the connection point of the two platform plates 1 are adjacent, and the locking buckle 4 can lock the two adjacent slot edges 11, making the two slot edges 11 relatively fixed and ensuring the stability of the platform plate 1 in the unfolded state. The landing marking 3 makes the landing platform easier to identify. Through the above technical solutions, the safety and practicality of the drone landing pad are effectively improved, and its application scope is expanded.

[0030] The two platform plates 1 mentioned above have the same structure, both having a top surface and a bottom surface. When in use, the two platform plates 1 are unfolded, and their top surfaces can be connected to form a flat parking platform. When not in use, the two platform plates 1 are folded upwards so that the two top surfaces are pressed together, and the two storage slots on the bottom surface face outwards, which are used to store the folded telescopic outriggers 2. This ensures that the folded parking platform has no structure protruding from the storage slots, making it easy to move and store.

[0031] In this embodiment, the shape of the platform plate 1 can be set according to the shutdown requirements. It can be semi-circular, rectangular or square, and the resulting shutdown platform can be circular, square or rectangular. There is no limitation here. The number of telescopic legs 2 can be set as needed. For example, when the shape of the platform plate 1 is rectangular or square, the number of telescopic legs 2 is four, and they are set at the same relative position on the platform plate 1, which makes it easier to mass-produce and assemble the device.

[0032] Preferably, the top surface of the platform plate 1 is also provided with at least two levels, which are arranged perpendicularly to each other on adjacent edges of the platform plate 1 to improve the accuracy of the measurement.

[0033] In one specific embodiment, the platform plate 1 is hinged by a hinge 5, and the top surface of the platform plate 1 is provided with a mounting groove that matches the hinge 5.

[0034] The aforementioned groove edges 11 are provided on the four edges of the bottom surface of the platform plate 1, all perpendicular to the bottom surface of the platform plate 1, and their height is adapted to the height of the telescopic support leg 2 protruding from the bottom surface of the platform plate 1 after folding. By providing the groove edges 11, not only are storage grooves formed, but the structural strength of the platform plate 1 can also be strengthened to prevent the platform plate 1 from deforming.

[0035] Furthermore, in the embodiments of this application, such as Figure 3 As shown, a connecting sleeve 12 is provided at the end of the bottom surface of the platform plate 1 away from the locking buckle 4. The connecting sleeve 12 has a folding opening facing the locking buckle 4 and a support opening facing away from the platform plate 1. The telescopic support leg 2 is connected to the connecting sleeve 12 by a pin and is engaged with the folding opening when folded and with the support opening when unfolded. The aforementioned connecting sleeve 12 is used to connect the telescopic outrigger 2. By placing it on the bottom surface of the platform plate 1 away from the locking buckle 4, it not only provides more space for the folded telescopic outrigger 2, but also allows the telescopic outrigger 2 to be supported on the edge of the parking platform during use, which helps to improve the stability of the overall structure. The telescopic outrigger 2 is rotatably connected to the connecting sleeve 12 via a pin, allowing the telescopic outrigger 2 to easily switch between folded and supported states. When the telescopic outrigger 2 passes through the folding opening, the telescopic outrigger 2 is in the folded state, and the locking mechanism ensures that it is stably fixed in the folded state and will not turn out of the storage slot. When the telescopic outrigger 2 passes through the support opening, the telescopic outrigger 2 is in the supported state, and the locking mechanism ensures that it is stably fixed in the supported state and will not easily rotate, ensuring the stability of the parking apron. The aforementioned folding opening and support opening are perpendicular to each other, that is, the telescopic outrigger 2 can be folded or supported by rotating 90 degrees. When it is in the supported state, the telescopic outrigger 2 is perpendicular to the platform plate 1.

[0036] Furthermore, in the embodiments of this application, such as Figure 4As shown, the telescopic outrigger 2 includes a connector 21, a stud 22, and a telescopic joint 23 arranged in sequence. The connector 21 is adapted to the connecting sleeve 12, and a pin is inserted through the connector 21. A fastening washer 24 is slidably connected to the outside of the stud 22. The telescopic joint 23 is sleeved on the stud 22 and threadedly connected to the stud 22. The connector 21 is rotatably connected to the connecting sleeve 12 via a pin. The shape and size of the connector 21 are adapted to the connecting sleeve 12, allowing it to rotate freely within the connecting sleeve 12. The aforementioned fastening washer 24 and telescopic joint 23 cooperate to tighten the connecting sleeve 12 when necessary. Specifically, by rotating the telescopic joint 23, it moves towards the connecting sleeve, causing the fastening washer 24 to move along the stud 22 towards the connecting sleeve 12. The outer contour of the fastening washer 24 is larger than the folding opening and the support opening, allowing it to press against the folding opening or the support opening under the action of the telescopic joint 23, thereby restricting the rotation of the connector 21 relative to the connecting sleeve 12 and firmly fixing the telescopic leg 2 in the folded or supported state. When it is necessary to rotate the telescopic leg 2, adjusting the telescopic joint 23 to move away from the two sleeve sections will loosen the fastening washer 24, allowing the connector 21 to rotate relative to the connecting sleeve 12, thus enabling the telescopic leg 2 to switch between the folded and supported states. The operation is simple and easy to control.

[0037] Furthermore, in this embodiment, the fastening washer 24 has sufficient compressive strength and hardness to withstand the pressure when the expansion joint 23 is tightened; it also has a certain elastic recovery capability, and when compressed, it directly forms sufficient friction with the connecting sleeve 12, and can be reused multiple times to ensure its good fixing effect.

[0038] In one of the optional technical solutions of the above embodiments, such as Figure 3 As shown, the connecting sleeve 12 includes a limiting plate 121 and a connecting plate 122. The limiting plate 121 is parallel to the groove edge 11 connected to the locking buckle 4. The connecting plate 122 is perpendicularly connected to the opposite ends of the limiting plate 121 and has a connecting hole adapted to the pin. The two connecting plates 122 form a folding opening, and the connecting plate 122 and the limiting plate 121 form a support opening. When the telescopic outrigger 2 passes through the support opening, one end face of the connector 21 abuts against the connecting plate 122. The connecting plate 122 cooperates with the fastening washer 24 to limit the connection head 21, so that the telescopic outrigger 2 is fixed in a state perpendicular to the platform plate 1, ensuring the stability of the apron.

[0039] Furthermore, in the above embodiment, the connector 21 is a cuboid with five chamfered sides, and through holes for mounting pins are provided on two opposite sides. When it is rotated to the point where the telescopic support leg 2 is perpendicular to the platform plate 1, one side of it just abuts against the limiting plate 121.

[0040] Furthermore, in the embodiments of this application, such as Figure 4 As shown, the telescopic joint 23 includes several nestable pipe sections 231, with the ends of the telescopic joint 23 having a pointed structure. Specifically, the number of pipe sections 231 can be set as needed. One pipe section 231 near the fastening washer 24 has an internal thread and is threadedly connected to the stud 22 to control the movement of the fastening washer 24. The end of one pipe section 231 away from the fastening washer 24 can be inserted into the ground soil through the pointed structure, so that the telescopic outrigger 2 can be more firmly fixed on the ground. Each pipe section 231 has an opening and a cavity. Among two adjacent pipe sections 231, the pipe section 231 that is relatively far from the platform plate 1 can be embedded in the cavity of the pipe section 231 that is close to the platform plate 1, and its length extending into the other pipe section 231 can be adjusted as needed to change the overall length of the telescopic outrigger 2 to adapt to different terrain conditions and ensure that the levelness of the landing platform meets the requirements for UAV take-off and landing.

[0041] Furthermore, in the above embodiment, the expansion joint 23 further includes a fastening sleeve 232, the two ends of which are threadedly connected to two pipe sections 231 respectively; among adjacent pipe sections 231, the inner diameter of the pipe section 231 closer to the platform plate 1 is larger than the outer diameter of the other pipe section 231. The fastening sleeve 232 is used to connect two adjacent pipe sections 231; specifically, the pipe section 231 connected to the stud 22 has an external thread at the end away from the stud 22, the pipe section 231 with a pointed structure has an external thread at the end away from the pointed structure, and the pipe section 231 between the two has external threads at at least both ends; the fastening sleeve 232 is a hollow structure with open ends, the inner side of the end closer to the platform plate 1 has an upper thread, and the inner side of the end away from the platform plate 1 has a lower thread, the upper thread and the lower thread are respectively threaded to... The external threads of the two pipe sections 231 are matched to achieve the threaded connection between the fastening sleeve 232 and the pipe section 231. By designing the inner and outer diameters of the adjacent pipe sections 231, the inner diameter of the pipe section 231 closer to the platform plate 1 is larger than the outer diameter of the other pipe section 231, so that the pipe section 231 farther from the platform plate 1 can be embedded in the pipe section 231 closer to the platform plate 1. Through the above technical solution, the adjacent pipe sections 231 can be nested and connected, and can also be extended through the fastening sleeve 232, thereby adjusting the length of the expansion joint 23.

[0042] Preferably, at least one pipe section 231 has a contraction port 2311 at its end away from the platform plate 1, and the inner side of the connection end between the fastening sleeve 232 and the contraction port 2311 has an internal thread that gradually contracts from the outside to the inside. Through this technical solution, when the fastening sleeve 232 moves closer to the platform plate 1, the contraction port 2311 contracts inward, which can clamp another pipe section 231 embedded within the pipe section 231, thereby controlling the insertion length of the pipe section 231 and realizing continuous adjustment of the length of the expansion joint 23, which is more convenient and faster. Preferably, each pipe section 231 of the expansion joint 23 has a contraction port, and each fastening sleeve 232 has a matching internal thread, so that the connection length between adjacent pipe sections 231 can be controlled by the fastening sleeve 232.

[0043] Furthermore, in the embodiments of this application, such as Figure 5 As shown, the locking buckle 4 includes a fastener 41 and a locking member 42. The fastener 41 is slidably connected to a sliding groove 111 provided on the groove edge 11, and has a locking space for accommodating the two groove edges 11. The locking member 42 is threadedly connected to the fastener 41 and is used to adjust the size of the locking space to lock the two groove edges 11. In use, after the two platform plates 1 are unfolded, the two groove edges 11 at the connection part of the two platform plates 1 are adjacent to each other, preferably, the two groove edges 11 are fitted together. By moving the fastener 41, the two groove edges 11 can be fitted into the locking space of the fastener 41, and then the two groove edges 11 are locked by rotating the locking member 42, thereby fixing the two groove edges 11. This can effectively prevent the two platform plates 1 from flipping upwards, thus ensuring the stability of the unfolded landing platform, so as to facilitate more reliable take-off and landing of UAVs.

[0044] In one of the optional technical solutions of the above embodiments, such as Figure 5As shown, the fastener 41 includes a sliding part 411 and a locking part 412. The sliding part 411 and the locking part 412 are arranged opposite to each other to form a locking space. One end of the sliding part 411 is provided with anti-disengagement ears that protrude to both sides and can be engaged with the sliding groove 111. The locking member 42 passes through the locking part 412, and one end of it that extends into the locking space is provided with a fastening pressure plate 421. Specifically, one of the groove edges 11 at the connection of the platform plates 1 is provided with a sliding groove 111. The opening of the sliding groove 111 faces away from the platform plate 1 and is adapted to the shape of the sliding part 411. The sliding part 411 can move along the sliding groove 111 towards or away from the platform plate 1. There is a set interval between the sliding part 411 and the locking part 412, and the resulting locking space is greater than the sum of the thicknesses of the two groove edges 11. Preferably, the sliding part 411 and the locking part 412 are connected by a connecting part on one side to form a U-shaped structure. The lengths of the sliding part 411 and the locking part 412 are set according to the height of the groove edge 11, and the length of the sliding part 411 is greater than that of the locking part 412. The locking member 42 passes through the middle of the locking part 412. It is threadedly connected to the locking part 412. In use, first move the fastener 41 away from the platform plate 1 to leave enough space for the locking part 412 so that the two groove edges 11 of the two platform plates 1 fit together after unfolding. Then control the fastener 41 to move closer to the platform plate 1 so that the fastener 41 fits on the outside of the two groove edges 11. Then tighten the locking part 42 so that the fastening pressure plate 421 of the locking part 42 presses against one of the groove edges 11 to fix the two groove edges 11. However, when it is necessary to fold the platform plate 1, loosen the locking part 42 and move the fastener 41 away from the platform plate 1 to release the lock and leave enough space for the groove edges 11 to flip. The operation is convenient, quick and easy to control.

[0045] When using the foldable all-terrain UAV landing pad proposed in this application, first, the two platform plates 1 are inverted and unfolded. After locking the two grooved edges 11 of the connecting part with the locking buckle 4, the first pipe section 231 near the platform plate 1 is screwed on to move the fastening washer 24 away from the connecting sleeve 12. Then, the telescopic outrigger 2 is rotated 90 degrees so that the telescopic outrigger 2 is perpendicular to the platform plate 1. The first pipe section 231 near the platform plate 1 is screwed on again to lock the fastening washer 24 into the connecting sleeve 12. Then, the landing platform is flipped over so that the telescopic outrigger 2 faces downwards, and its pointed structure at the bottom is inserted into the soil or rock. Ensure the telescopic outriggers 2 are securely fixed; then, adjust the length of the telescopic outriggers 2 according to the terrain conditions using the fastening sleeves 232, and use a level on the landing platform to ensure that the landing platform is level, thus completing the setup of the all-terrain UAV landing pad; after the UAV has finished its operation, adjust the telescopic outriggers 2 to shorten them again, and control the loosening and tightening of the fastening washers 24 to rotate and fold the telescopic outriggers 2 and fix them in the storage slot; then adjust the locking buckles 4 to loosen the two slot edges 11, and the two platform plates 1 can be folded; the folded all-terrain UAV landing pad occupies little space and is easy to carry and move.

[0046] The advantages and positive effects of this utility model are:

[0047] (1) By setting telescopic outriggers, the height of the landing platform above the ground can be adjusted to eliminate the adverse effects of surrounding weeds and other debris on the take-off and landing of the drone; at the same time, the length of different telescopic outriggers can be adjusted according to complex terrain conditions to ensure that the level of the landing platform meets the requirements for the take-off and landing of the drone.

[0048] (2) The telescopic outriggers can be folded and stored in the storage slot at the bottom of the platform, which reduces the space occupied by the helipad, makes them easier to carry and move, and is less likely to be damaged by bumps.

[0049] (3) By setting up telescopic ports and fastening sleeves, the two work together to make it easier and more convenient to adjust the length of telescopic outriggers, with precise adjustment and easy control;

[0050] (4) By setting a locking buckle, the two groove edges at the connection of the platform plate can be locked when the platform is unfolded, ensuring the stability of the platform plate in the unfolded state.

[0051] (5) The overall device has a simple structure, is easy to manufacture, easy to use and carry, and can be reused multiple times.

[0052] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
