Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV landing cushioning airbag. Background Technology

[0002] With their flexibility, maneuverability, and ease of operation, drones have been widely used in many fields such as aerial photography, surveying and mapping, inspection, and logistics.

[0003] The landing phase is a highly vulnerable stage in drone operations. However, traditional drone landing gear is a rigid or simply elastic structure, which is ineffective at cushioning impacts when encountering uneven ground, excessive landing speed, or sudden turbulence. This can easily damage the drone's fuselage, internal electronic components, or onboard equipment, and in severe cases, cause the drone to overturn or crash, resulting in economic losses and even hindering mission completion. Therefore, we have developed a drone landing cushioning airbag. Utility Model Content

[0004] The main objective of this invention is to provide a landing cushioning airbag for unmanned aerial vehicles (UAVs), which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A drone landing cushioning airbag includes a mounting plate, a fixing component fixedly connected to the upper end of the mounting plate, a cushioning component pastedly connected to the upper end of the fixing component, a left support component fixedly connected to the left end of the mounting plate, and a right support component fixedly connected to the right end of the mounting plate.

[0007] Preferably, the cushioning assembly includes a cushioning airbag body, an inflation tube is fixedly connected to the outer surface of the cushioning airbag body, a one-way valve is movably installed on the outer surface of the inflation tube, a sealing plug is movably sleeved inside the inflation tube, and Velcro fasteners are fixedly connected to the four corners of the outer surface of the cushioning airbag body.

[0008] By adopting the above technical solution: the inflation tube facilitates the inflation of the cushioning airbag body, the one-way valve prevents gas leakage, and the sealing plug ensures airtightness.

[0009] Preferably, the fixing component includes a drone bottom fixing plate, and fixing blocks are fixedly connected to the four corners of the drone bottom fixing plate. Each of the four fixing blocks has an upper and lower opening.

[0010] Through-hole fixing holes, Velcro hooks are fixedly connected to the four corners of the upper part of the bottom fixing plate of the drone, and the lower end of the bottom fixing plate of the drone is fixedly connected to the upper end of the mounting plate.

[0011] By adopting the above technical solution, the bottom mounting plate of the drone is stably connected to the drone through mounting blocks and mounting holes.

[0012] Preferably, the lower ends of the four hook and loop fastener surfaces are respectively attached to the upper ends of the four corresponding hook and loop fastener surfaces.

[0013] By adopting the above technical solution, the buffer component and the fixing component are tightly bonded, ensuring the stability of the buffer airbag body during use, avoiding displacement that affects the buffering effect, and simplifying the installation and disassembly process.

[0014] Preferably, the right support assembly includes a base plate, with a plurality of arc-shaped elastic buffer leaves fixedly connected to the upper end of the base plate. The upper ends of the plurality of arc-shaped elastic buffer leaves are jointly fixedly connected to a drone bottom contact plate. Two support rods are fixedly connected to the lower end of the base plate, and the lower ends of the two support rods are jointly fixedly connected to a foot. A bottom rubber buffer pad is fixedly connected to the lower end of the foot. Edge buffer blocks are fixedly connected to the front and rear ends of the foot. The left end of the base plate is fixedly connected to the right end of the mounting plate.

[0015] By adopting the above technical solution, the arc-shaped elastic buffer leaf, the bottom rubber buffer pad and the edge buffer block form a multi-buffer structure, which can effectively absorb the impact force of landing, and the support rod and the foot provide stable support, protecting the drone from vibration damage.

[0016] Preferably, the plurality of the arc-shaped elastic buffer leaves are configured as arc-shaped structures that bend to the right in the middle, and the plurality of the arc-shaped elastic buffer leaves are distributed in pairs at equal distances.

[0017] By adopting the above technical solutions: the arc-shaped structure enhances the deformation capacity and improves the buffering effect; the equidistant distribution ensures uniform stress distribution, avoids excessive local stress, and extends the service life of the support components.

[0018] Preferably, the left support component and the right support component have the same structure and are distributed in a mirror image.

[0019] By adopting the above technical solutions, the symmetrical structure ensures the force balance during drone landing, prevents tipping, improves the overall buffer stability and reliability, and adapts to different landing scenarios.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In this utility model, when the drone lands, the rubber buffer pads at the bottom of the right and left support components first contact the ground, and the edge buffer blocks assist in buffering, initially absorbing part of the impact force. At the same time, the arc-shaped elastic buffer leaf deforms under pressure, and uses its elasticity to further absorb the impact force. The drone bottom contact plate evenly transmits the force to the arc-shaped elastic buffer leaf to avoid excessive local force. If the impact force is large, the buffer airbag body will further play its role, absorbing energy through its own elastic deformation. The multiple buffer structures work together to significantly reduce the vibration of the drone, effectively protect the drone and its onboard equipment, have a good buffering effect, significantly improve the safety of drone landing, and extend the service life of the drone.

[0022] 2. In this utility model, the sealing plug inside the inflation tube is removed, and air is inflated into the buffer airbag body through the inflation tube. The one-way valve can prevent gas leakage during inflation, ensuring that the buffer airbag body can be inflated to a suitable air pressure, providing a sufficient elastic foundation for cushioning. After inflation, the sealing plug is put back in to ensure that the gas does not leak out. The Velcro hooks at the four corners of the outer surface of the buffer airbag body of the buffer assembly are attached to the Velcro hooks at the four corners of the upper part of the drone bottom fixing plate in the fixing assembly. This attachment method not only makes the buffer airbag body flat and attached to the drone bottom fixing plate, making installation and disassembly convenient, but also ensures that the buffer airbag body is stable in position during use and will not easily shift. Through the fixing holes on the fixing blocks around the drone bottom fixing plate in the fixing assembly, bolts are used to install it on the bottom of the drone. At this time, the buffer airbag body is tightly attached to the bottom of the drone, and the drone bottom contact plates of the left support assembly and the right support assembly are also tightly attached to the bottom of the drone, realizing a stable connection between the buffer structure and the drone, without affecting the normal flight attitude of the drone.

The left support assembly 4 and the right support assembly 5 have the same structure and are distributed in a mirror image.

[0037] It should be noted that this utility model is a drone landing cushioning airbag. In use, the sealing plug 34 inside the inflation tube 32 is removed, and air is inflated into the cushioning airbag body 31 through the inflation tube 32. During inflation, the one-way valve 33 prevents gas leakage. After inflation, the sealing plug 34 is reinserted into the inflation tube 32.
