Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles (UAVs), in particular to a take-off and landing platform for low-altitude logistics UAVs. Background Art

[0002] With advances in drone technology, drones are increasingly being used in logistics. Drones can provide near-point, linear logistics transport at low altitudes, offering fast and efficient transportation. However, when a drone lands with cargo, it is susceptible to impact, a phenomenon that becomes more pronounced as the weight of the cargo increases. As the number of drone landings increases, this impact can negatively impact the drone's service life. Under current technology, drone landing platforms generally lack shock-absorbing measures to mitigate the impact of landing, relying primarily on the drone's own shock-absorbing mechanisms to mitigate the adverse effects, with limited effectiveness. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a take-off and landing platform for a low-altitude logistics UAV.

[0004] The technical solution of this utility model is a take-off and landing platform for a low-altitude logistics drone, comprising a mobile platform and a base, elastically connected to the base via a shock-absorbing assembly. The shock-absorbing assembly comprises guide rods, a vertical cylinder, and a return spring. The base of the mobile platform is provided with multiple symmetrically distributed guide rods, and the base is provided with vertical cylinders in positions corresponding to the guide rods. One end of the guide rod is fixedly connected to the mobile platform, and the other end is provided with a piston that engages the through cylinder. A return spring is provided between the inner bottom of the vertical cylinder and the piston.

[0005] Furthermore, an opening is provided on the movable platform for goods to pass through, and an expansion groove is provided at a position of the base corresponding to the opening.

[0006] Furthermore, a side of the mobile platform away from the base is provided with an anti-skid pad, a side of the anti-skid pad in contact with the mobile platform is provided with a positioning block, and the mobile platform is provided with a positioning groove that cooperates with the positioning block.

[0007] Furthermore, a detachable end cover is provided on the top surface of the vertical cylinder, the guide rod passes through the end cover, and a linear bearing is provided between the end cover and the guide rod.

[0008] Furthermore, a buffer pad is provided between the end cover and the bottom surface of the movable platform.

[0009] Furthermore, a plurality of fins with even intervals are provided on the circumference of the outer side surface of the vertical cylinder.

[0010] Furthermore, the base includes a vertical cylinder, a bottom plate and support legs. The vertical cylinder is provided on the top of the bottom plate, and a plurality of symmetrically distributed support legs are provided on the bottom surface.

[0011] Furthermore, the support leg includes a threaded barrel, a threaded rod, and a fixed plate. One end of the threaded barrel is fixedly connected to the base plate, and the other end is for the threaded rod to pass through. The upper end of the threaded rod is threadedly connected to the barrel, and the other end is rotatably connected to the fixed plate via a ball joint. A universal level is provided on the base.

[0012] Compared with existing technologies, the advantages of this utility model are: the piston and vertical cylinder cooperate to convert the impact potential energy of the drone during landing into frictional heat energy, thereby reducing the damage caused by the impact. The return spring automatically returns the mobile platform to its initial position, allowing the lifting platform to absorb the impact of multiple drone landings. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described clearly and completely below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments derived by persons of ordinary skill in the art without inventive effort are also within the scope of protection of the present invention.

[0020] The specific implementation of the present invention will be described below with reference to the accompanying drawings:

[0021] like Figures 1 to 4 As shown, a take-off and landing platform for a low-altitude logistics drone includes a mobile platform 2 and a base 1, with the mobile platform 2 and base 1 elastically connected via a shock-absorbing assembly. The shock-absorbing assembly includes guide rods 22, a vertical cylinder 12, and a return spring 125. The bottom of the mobile platform 2 is provided with multiple symmetrically distributed guide rods 22, and the base 1 is provided with vertical cylinders 12 at positions corresponding to the guide rods 22. One end of the guide rods 22 is fixedly connected to the mobile platform 2, and the other end is provided with a piston 221 that mates with the through cylinder. A return spring 125 is provided between the inner bottom of the vertical cylinder 12 and the piston 221. When the drone lands on the mobile platform 2, the mobile platform 2 drives the guide rods 22 downward, causing the piston 221 to rub against the inner wall of the vertical cylinder 12, thereby converting the impact potential energy and reducing the impact of the drone landing. After the impact is reduced, the return spring 125 returns the mobile platform 2 to its initial position, preparing for the next drone landing. The shock-absorbing assembly absorbs the impact potential energy of the drone landing, preventing damage to the drone due to excessive impact.

[0022] The mobile platform 2 has an opening 3 for cargo to pass through, and the base 1 has a flared slot 112 at the location corresponding to opening 3. After the drone lands on the mobile platform 2, cargo can pass through the opening 3 and be transported out through the flared slot 112, making it easier to retrieve the cargo. The side of the mobile platform 2 facing away from the base 1 is equipped with an anti-slip pad 21. The side of the anti-slip pad 21 that contacts the mobile platform 2 has a positioning block, and the mobile platform 2 has a positioning slot 211 that mates with the positioning block. The anti-slip pad 21 prevents the drone from slipping during landing, ensuring a stable landing on the mobile platform 2. The removable anti-slip pad 21 is easy to replace.

[0023] The top surface of the vertical cylinder 12 is provided with a removable end cover 121, and the guide rod 22 passes through the end cover 121. A linear bearing 124 is provided between the end cover 121 and the guide rod 22. The end cover 121 can prevent debris from falling from the top of the vertical cylinder 12 into the interior of the vertical cylinder 12, and the friction between the end cover 121 and the guide rod 22 is reduced by the linear bearing 124. A buffer pad 122 is provided between the end cover 121 and the bottom surface of the movable platform 2, and the buffer pad 122 can prevent a rigid collision between the movable platform 2 and the end cover 121. A plurality of evenly spaced fins 123 are provided on the circumference of the outer side surface of the vertical cylinder 12. The fins 123 are conducive to the rapid dissipation of heat from the sliding friction of the piston 221 by the vertical cylinder 12, and are conducive to the rapid dissipation of impact potential energy in the form of heat energy.

[0024] The base 1 includes a vertical tube 12, a bottom plate 11, and support legs 13. The vertical tube 12 is provided on the top of the bottom plate 11, and a plurality of symmetrically distributed support legs 13 are provided on the bottom surface. The support legs 13 provide stable support for the entire lifting platform. The support legs 13 include a threaded tube 131, a threaded rod 132, and a fixed plate 133. One end of the threaded tube 131 is fixedly connected to the bottom plate 11, and the other end is for the threaded rod 132 to pass through. The upper end of the threaded rod 132 is threadedly connected to the threaded tube 131, and the other end is rotatably connected to the fixed plate 133 via a ball joint 1321. The rotating fixed plate 133 helps the bottom of the support leg 13 adapt to an uneven work surface. A through hole 1331 is provided on the fixed plate 133, and a fastener is provided in the through hole 1331 to fix the lifting platform to the work surface. A rotating block 1322 is provided on the threaded rod 132, which facilitates the rotation of the threaded rod 132. By adjusting the length of the threaded rod 132 screwed into the threaded barrel 131, the length of the support legs 13 is changed to adapt the base 1 to an uneven work surface. The universal level 111 on the base 1 can quickly detect whether the base 1 is in a horizontal state.

[0025] The operating principle of this embodiment of the utility model is as follows: a drone carrying cargo lands on mobile platform 2. Under the impact of the drone, mobile platform 2 moves downward, compressing return spring 125. The piston 221 slides and rubs against vertical cylinder 12, dissipating the impact potential energy as heat, thereby reducing the adverse effects of the impact on the drone. After the impact is reduced, mobile platform 2 returns to its initial position under the action of return spring 125, preparing for the next landing of the drone.
