Description

Technical Field

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

[0002] A drone helipad is a facility specifically designed for parking drones and is widely used in various scenarios, such as power line inspection, agricultural monitoring, and environmental monitoring.

[0003] A search of publication number CN 221738161 U reveals an adaptive drone landing pad, comprising a circular landing platform. Its key feature is the presence of a connecting rod at the center of the platform's bottom surface. A counterweight is fixed to the lower end of the connecting rod, and a sphere is positioned above the connecting rod. A support sleeve is fitted around the sphere via a spherical fit. A tripod (an octopus-style tripod) is connected to one side of the support sleeve via an L-shaped arm. Because of the octopus-style tripod, the landing pad can be used on various uneven surfaces. With the counterweight fixed to the lower end of the connecting rod at the center of the platform's bottom surface and the sphere above the connecting rod, the platform automatically maintains a level position under the weight of the counterweight, thus achieving automatic leveling and ensuring safe takeoff and landing of the drone. The structure is simple and easy to use.

[0004] Although the aforementioned document implements an adaptive leveling function, after leveling, it mainly fixes the sphere inside the support sleeve by locking screws on one side of the support sleeve, thereby fixing the landing pad. While this method can achieve a certain level of fixation, its effectiveness is limited. Especially when the landing pad is used outdoors, it is easily affected by wind and other factors, which can cause the sphere to rotate inside the support sleeve, causing the landing pad to tilt again and affecting normal use. In view of this, we propose an adaptive UAV landing pad. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide an adaptive drone landing pad to solve the technical problem of poor fixation effect of current adaptive drone landing pads.

[0006] To solve the above technical problems, this utility model provides the following technical solution: an adaptive UAV landing pad, including a base, a support is arranged on the top of the base, a leveling structure is arranged at the center of the top of the support, a landing platform is arranged on the top of the leveling structure, a mating structure is rotatably arranged at the bottom of the landing platform, four sets of equidistant fixing rods are slidably arranged around the bottom of the mating structure, and the fixing rods penetrate the support, and a fixing structure is arranged at the bottom of the support corresponding to the fixing rods;

[0007] The base is equipped with a synchronous drive structure, which includes a chassis and an L-shaped connecting rod. The chassis is rotatably mounted on the top of the base. The top of the chassis has four sets of arc-shaped grooves corresponding to the L-shaped connecting rods, and the arc-shaped grooves are bent inward. The L-shaped connecting rods are mounted on a fixed structure, and the bottom end of the L-shaped connecting rods extends into the corresponding arc-shaped grooves. Several sets of grip rods are equidistantly arranged around the chassis.

[0008] This utility model, through its designed mating structure, fixing rods, and fixing mechanism, allows the following: After the base is placed, pulling the rectangular rod on the fixing mechanism separates the toothed plate from the fixing rod. At this point, the leveling structure automatically levels the stopping platform. Furthermore, with the cooperation of the mating structure, the four sets of fixing rods at the bottom adaptively move and rise. Once the stopping platform is leveled, releasing the rectangular rod allows the toothed plate to return to its original position under the spring's reset mechanism. The toothed plate then engages with the toothed grooves on the fixing rods, thus securing the fixing rods. The four sets of fixing rods can then be directly... Fixing the leveled platform greatly ensures its stability and prevents it from tilting again due to wind or external impact. This invention also features a synchronous drive structure with an inwardly curved arc groove on the chassis. By rotating the chassis, the arc groove and L-shaped connecting rod simultaneously pull the rectangular rods in the four fixed structures, separating the four toothed plates from their corresponding fixed rods. This allows the four fixed rods to move and adjust more easily in conjunction with the leveling structure.

[0009] Preferably, the leveling structure includes a mounting sleeve, which is arranged at the center of the top of the bracket. A sphere is movably arranged inside the mounting sleeve, a support rod is arranged on the sphere, a counterweight is arranged at the bottom of the support rod, and the top of the support rod is connected to the center of the bottom of the parking platform.

[0010] Preferably, the mounting sleeve has several sets of balls arranged at equal intervals inside, and the balls are in contact with the sphere.

[0011] Preferably, the mating structure includes a ring, which is rotatably arranged at the bottom of the parking platform. Four sets of mating rods are equidistantly arranged at the bottom of the ring. A T-shaped groove is provided at the bottom of the mating rod. A T-shaped slider is slidably arranged inside the T-shaped groove. The T-shaped slider is connected to the corresponding fixed rod.

[0012] Preferably, the fixing rod is provided with limit strips on its front and rear sides, and the top of the bracket is provided with a through hole corresponding to the fixing rod, and the through hole is cross-shaped.

[0013] Preferably, the fixing rod has a toothed groove on the side facing the fixing structure. The fixing structure includes a welding plate, which is arranged on the bracket. A rectangular rod is arranged through the welding plate. A toothed plate is arranged at one end of the rectangular rod facing the fixing rod. A disc is arranged at the end of the rectangular rod facing away from the toothed plate. A spring is arranged between the disc and the welding plate. The disc is connected to an L-shaped connecting rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through its designed mating structure, fixing rods, and fixing structure, allows the platform to automatically level itself after the base is placed. Pulling the rectangular rod on the fixing structure separates the toothed plate from the fixing rod. The leveling structure then coordinates with the four fixing rods at the bottom to move and rise adaptively. Once the platform is leveled, releasing the rectangular rod allows the toothed plate to reset with the spring's return mechanism. The toothed plate then engages with the toothed grooves on the fixing rods, securing them. The four fixing rods then directly fix the leveled platform, greatly ensuring its stability and preventing tilting due to wind or external impacts. This solves the problem of poor fixation in current adaptive UAV landing pads. Therefore, this utility model offers superior fixation after platform leveling.

[0016] 2. This utility model also features a synchronous drive structure with an inwardly curved arc groove on the chassis. By rotating the chassis, the rectangular rods in the four fixed structures can be pulled synchronously in conjunction with the arc groove and the L-shaped connecting rod. This allows the four toothed plates to separate from their corresponding fixed rods, making it easier for the four fixed rods to move and adjust in conjunction with the leveling structure.

[0025] like Figures 1 to 6As shown, this utility model relates to an adaptive UAV landing pad, including a base 1, a support 2 on the top of the base 1, a leveling structure 3 at the center of the top of the support 2, a landing platform 4 on the top of the leveling structure 3, a mating structure 5 rotatably arranged at the bottom of the landing platform 4, four sets of equidistant fixing rods 6 sliding around the bottom of the mating structure 5, and the fixing rods 6 penetrating the support 2. A fixing structure 7 is arranged at the bottom of the support 2 corresponding to the fixing rods 6; the fixing rods 6 have toothed grooves 601 on the side facing the fixing structure 7; the fixing structure 7 includes a welding plate 701, which is arranged on the support 2, and a rectangular rod 702 is arranged through the welding plate 701. A toothed plate 705 is arranged at one end of the rectangular rod 702 facing the fixing rod 6, and a disc 704 is arranged at the end of the rectangular rod 702 facing away from the toothed plate 705. A spring 703 is arranged between the disc 704 and the welding plate 701, and the disc 704 is connected to an L-shaped connecting rod 802. Connection; When placing the device, first place the base 1 on the ground, then pull the rectangular rod 702 on the fixing structure 7, causing the toothed plate 705 to separate from the toothed groove 601 of the fixing rod 6. At this time, under the action of the leveling structure 3, the landing platform 4 will automatically level itself. With the cooperation of the cooperating structure 5, the four sets of fixing rods 6 at the bottom will move and rise adaptively as the landing platform 4 moves. After the landing platform 4 is leveled, release the rectangular rod 702. With the reset cooperation of the spring 703, the toothed plate 705 will reset. At this time, the toothed plate 705 will engage with the toothed groove 601 on the fixing rod 6, thereby fixing the fixing rod 6. Then, the four sets of fixing rods 6 can directly fix the leveled landing platform 4, which can greatly ensure the stability of the landing platform 4 and prevent the landing platform 4 from tilting again due to wind or foreign object contact, thus ensuring the stability of the UAV placed horizontally on the landing platform 4.

[0026] Specifically, the leveling structure 3 includes a mounting sleeve 301, which is located at the top center of the bracket 2. A ball 303 is movably arranged inside the mounting sleeve 301, and a support rod 302 is arranged on the ball 303. A counterweight 304 is arranged at the bottom of the support rod 302, and the top of the support rod 302 is connected to the bottom center of the parking platform 4. Under the action of the counterweight 304, the ball 303 will rotate adaptively within the mounting sleeve 301 until the support rod 302 is in a vertical state. At this time, the parking platform 4 at the top of the support rod 302 is in a horizontal state.

[0027] Furthermore, several sets of balls 305 are equidistantly arranged inside the mounting sleeve 301. The balls 305 contact the ball 303. With the cooperation of the balls 305, the friction between the mounting sleeve 301 and the ball 303 can be greatly reduced, ensuring that the ball 303 can rotate smoothly inside the mounting sleeve 301.

[0028] Furthermore, the cooperating structure 5 includes a ring 501, which is rotatably arranged at the bottom of the parking platform 4. Four sets of cooperating rods 502 are equidistantly arranged at the bottom of the ring 501. The bottom of the cooperating rods 502 is provided with a T-shaped groove 503. A T-shaped slider 504 is slidably arranged inside the T-shaped groove 503. The T-shaped slider 504 is connected to the corresponding fixed rod 6. The rotatably arranged ring 501 is used to cooperate with the rotational movement that occurs during the leveling of the parking platform 4, which can prevent the fixed rod 6 from rotating. The cooperation between the T-shaped groove 503 and the T-shaped slider 504 can realize the sliding installation of the fixed rod 6 on the cooperating rod 502, which is used to cooperate with the tilting movement that occurs during the leveling of the parking platform 4, and prevent the fixed rod 6 from tilting. This ensures that the fixed rod 6 can always be perpendicular to the support 2. Therefore, with the cooperation of the cooperating structure 5, the four sets of fixed rods 6 can adaptively adjust in coordination with the leveling movement of the parking platform 4.

[0029] It is worth noting that the fixed rod 6 is provided with limit strips 602 on the front and rear sides, and the bracket 2 has a through hole 201 corresponding to the fixed rod 6 on the top. The through hole 201 is cross-shaped. The cross-shaped through hole 201 facilitates the passage of the limit strip 602 and the fixed rod 6. The limit strip 602 is used to vertically limit the fixed rod 6 and prevent the toothed groove 601 on the fixed rod 6 from getting stuck with the side of the through hole 201 when the fixed rod 6 is raised or lowered.

[0030] In an embodiment of this utility model, a synchronous drive structure 8 is arranged on the top of the base 1. The synchronous drive structure 8 includes a chassis 801 and an L-shaped connecting rod 802. The chassis 801 is rotatably arranged on the top of the base 1. The top of the chassis 801 has four sets of arc-shaped grooves 803 corresponding to the L-shaped connecting rods 802, and the arc-shaped grooves 803 are bent inward. The L-shaped connecting rods 802 are arranged on the fixed structure 7, and the bottom end of the L-shaped connecting rods 802 extends into the corresponding arc-shaped grooves 803. Several sets of grip rods 804 are equidistantly arranged around the chassis 801. By holding the grip rods 804 and rotating the chassis 801, the rectangular rods 702 in the four sets of fixed structures 7 can be pulled synchronously with the arc-shaped grooves 803 and the L-shaped connecting rods 802. That is, the four sets of toothed plates 705 are separated from the corresponding fixed rods 6, so that the four sets of fixed rods 6 can be more conveniently moved and adjusted with the leveling structure 3.

[0031] Working Principle: This embodiment provides an adaptive drone landing pad. First, when placing the device, the base 1 is placed on the ground. Then, the rectangular rod 702 on the fixing structure 7 is pulled, causing the toothed plate 705 to separate from the toothed groove 601 of the fixing rod 6. At this time, under the action of the leveling structure 3, the landing platform 4 will automatically level itself. With the cooperation of the cooperating structure 5, the four sets of fixing rods 6 at the bottom will move and rise adaptively as the landing platform 4 moves. After the landing platform 4 is leveled, the rectangular rod 702 is released. With the reset cooperation of the spring 703, the toothed plate 705 is reset. At this time, the toothed plate 705 will engage with the toothed groove 601 on the fixing rod 6, thereby fixing the fixing rod 6. Then, the four sets of fixing rods 6 can directly fix the leveled landing platform 4, which can greatly ensure the stability of the landing platform 4 and prevent the landing platform 4 from tilting again due to wind or foreign object contact, thus ensuring the stability of the drone placed horizontally on the landing platform 4.

[0032] Secondly, by holding the handle 804 and rotating the base 801, the rectangular rods 702 in the four fixed structures 7 can be pulled simultaneously with the cooperation of the arc groove 803 and the L-shaped connecting rod 802. This achieves the separation of the four toothed plates 705 from the corresponding fixed rods 6, thereby making it easier for the four fixed rods 6 to move and adjust in conjunction with the leveling structure 3.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
