Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles (UAVs), in particular to a landing protection structure for UAVs. Background Art

[0002] A drone is an unmanned aircraft controlled by a radio remote control and self-contained programmable controls, or operated fully or intermittently autonomously by an onboard computer. Compared to manned aircraft, drones are often better suited for missions deemed too "dull, dirty, or dangerous." Drones can be divided into military and civilian applications. In the military, drones are divided into reconnaissance and target drones. In the civilian sector, drones combined with industrial applications are a real necessity. Applications in aerial photography, agriculture, plant protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspections, disaster relief, film and television production, and creating romance have greatly expanded the uses of drones.

[0003] For example, the authorization announcement number is CN 220996813 U, which discloses a landing buffer structure for a drone, comprising a drone body, a fan blade fixedly connected to the drone body, a load-bearing column fixedly connected to the bottom of the drone body, a slot provided inside the load-bearing column, a first slide provided on the inner sidewall of the slot, a fixed rod fixedly connected to the inner bottom wall of the first slide, a connecting block slidably connected to the outside of the fixing rod, a push plate fixedly connected to one side of the connecting block, a sliding column fixedly connected to the bottom of the push plate, a second slide provided on the outside of the sliding column, a limit plate fixedly connected to the inner sidewall of the slot, and a fixed plate fixedly connected to the bottom end of the sliding column. The utility model can provide multiple landing buffers and shock absorption for the drone body, while facilitating protection of the drone body, thereby improving the stability of the drone body and reducing people's property losses.

[0004] Sometimes, drones may tilt during landing due to external factors, causing the side of the drone to touch the ground first. The above-mentioned drone landing cushioning structure only cushions the bottom of the drone when the drone maintains a vertical landing, and does not protect the sides, making the drone prone to damage due to impact when it tilts and lands. Therefore, the market urgently needs to develop a drone landing protection structure to help people solve the existing problem. Utility Model Content

[0005] The purpose of the present invention is to provide a drone landing protection structure to solve the problem raised in the above-mentioned background technology that the current drone landing buffer structure only cushions the bottom of the drone when the drone is kept vertically landing, but does not protect the sides, which makes the drone easily damaged by impact when it lands at an angle.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a drone landing protection structure, including a drone body, wherein wing panels are fixedly connected to the front and rear ends of both sides of the lower end surface of the drone body, one end of the wing panel extends out of one side of the drone body and is fixedly connected to a damping telescopic rod at the lower end, the lower end of the telescopic end of the damping telescopic rod is fixedly connected to a support plate, a second rectangular support frame is fixedly connected between one side of the lower ends of the four support plates, an arc-shaped protective plate is fixedly connected to one side of the support plate, and the upper ends of the four arc-shaped protective plates are fixedly connected to the first rectangular support frame.

[0007] Preferably, both front and rear ends of the upper end of the UAV body are rotatably connected to support arms, and one end of the support arm is fixedly connected to a lift assembly.

[0008] Preferably, first threaded holes are provided at both front and rear ends of the lower end surface of the drone body, and the wing plate and the drone body are threadedly connected and fixed by first screws passing through the wing plate and then inserted into the first threaded holes.

[0009] Preferably, a buffer spring is provided outside the damping telescopic rod and between the wing plate and the support plate.

[0010] Preferably, a second threaded hole is provided at the lower end of the telescopic end of the damping telescopic rod.

[0011] Preferably, the second rectangular support frame and the support plate are fixed to the lower end of the telescopic end of the damping telescopic rod by a second screw that sequentially penetrates the second rectangular support frame and the support plate and then is inserted into the second threaded hole and threadedly connected therewith.

[0012] Preferably, the length of the support plate extends beyond the rotation radius of the support arm.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In this utility model, by setting the first rectangular support frame, the second rectangular support frame and the arc-shaped protective plate, if the drone body tilts during landing, the length of the support plate extends beyond the rotation radius of the support arm, so that the frame enclosing structure formed by the second rectangular support frame, the four arc-shaped protective plates and the first rectangular support frame will first contact the ground, thereby protecting the drone body and the lift assembly, and preventing the side of the drone body from directly hitting the ground and causing damage.

[0015] 2. In this utility model, a buffer spring is provided on the outside of the damping telescopic rod and between the wing plate and the support plate. When the drone body falls vertically, it first contacts the ground through the second rectangular support frame. The damping telescopic rod contracts, and the wing plate and the support plate simultaneously compress the buffer spring to absorb the impact force of the drone body falling, thereby preventing the drone body from being damaged due to a large impact force when the drone body falls at a fast speed.

[0016] 3. The frame structure of this utility model is designed to facilitate disassembly: the four wing panels are threadedly connected to the first threaded holes on the lower end surface of the drone body via first screws, allowing for easy removal from the drone body. Simultaneously, the second rectangular support frame and support panels are threadedly connected to the second threaded holes at the lower end of the telescopic damping rod via second screws, also allowing for easy removal from the rod. This design not only improves the landing safety of the drone body but also facilitates user disassembly and installation as needed, increasing flexibility and convenience.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figure 1-4The utility model provides an embodiment: a drone landing protection structure, including a drone body 1, with wing panels 2 fixedly connected to the front and rear ends of both sides of the lower end surface of the drone body 1, one end of the wing panel 2 extends out of one side of the drone body 1 and is fixedly connected to a damping telescopic rod 201 at the lower end, the lower end of the telescopic end of the damping telescopic rod 201 is fixedly connected to a support plate 3, one side of the lower ends of the four support plates 3 are commonly fixedly connected to a second rectangular support frame 4, one side of the support plate 3 is fixedly connected to an arc-shaped protective plate 301, and the upper ends of the four arc-shaped protective plates 301 are commonly fixedly connected to a first rectangular support frame 302.

[0024] Furthermore, the front and rear ends of both sides of the upper end of the drone body 1 are rotatably connected to support arms 103, and one end of the support arms 103 is fixedly connected to a lift assembly 104. The lift assembly 104 is opened to one side by rotating the support arms 103, and the four lift assemblies 104 provide lift to the drone body 1 at the same time, thereby enabling the drone body 1 to fly.

[0025] Furthermore, first threaded holes 101 are provided at both front and rear ends of the lower end surface of the drone body 1. The wing panels 2 and the drone body 1 are threadedly fixed by first screws 102 passing through the wing panels 2 and then inserted into the first threaded holes 101, so that the four wing panels 2 can be removed from the drone body 1.

[0026] Furthermore, a buffer spring 203 is provided on the outside of the damping telescopic rod 201 and between the wing plate 2 and the support plate 3. When the drone body 1 falls vertically, it first contacts the ground through the second rectangular support frame 4. The damping telescopic rod 201 contracts, and the wing plate 2 and the support plate 3 simultaneously compress the buffer spring 203 to absorb the impact force of the falling drone body 1, thereby preventing the drone body 1 from being damaged due to a large impact force when the drone body 1 falls at a fast speed.

[0027] Furthermore, a second threaded hole 202 is provided at the lower end of the telescopic end of the damping telescopic rod 201 .

[0028] Furthermore, the second rectangular support frame 4 and the support plate 3 are connected to the lower end of the telescopic end of the damping telescopic rod 201 by a second screw 5 that penetrates the second rectangular support frame 4 and the support plate 3 in sequence and then is inserted into the second threaded hole 202 for internal threaded connection and fixation. The upper ends of the four arc-shaped protective plates 301 are supported by the first rectangular support frame 302, and the lower ends of the four arc-shaped protective plates 301 are supported by the second rectangular support frame 4.

[0029] Furthermore, the length of the support plate 3 extends beyond the rotation radius of the support arm 103, so that the second rectangular support frame 4, the four arc-shaped protective plates 301 and the first rectangular support frame 302 form a frame enclosing structure for the drone body 1. When the drone tilts and lands, the frame enclosing structure contacts the ground first, protecting the drone body 1 and the lift assembly 104.

[0030] Working Principle: During use, the support arm 103 at the upper end of the drone body 1 is first rotated to open the lift assembly 104 to one side. The four lift assemblies 104 simultaneously provide lift to the drone body 1, enabling the drone body 1 to fly. When the drone body 1 needs to land, if the drone body 1 falls vertically, the second rectangular support frame 4 first contacts the ground. At this time, the damping telescopic rod 201 contracts, and the wing plate 2 and support plate 3 simultaneously compress the buffer spring 203, absorbing the impact force of the drone body 1 falling, preventing the drone body 1 from being damaged by the large impact force when the drone body 1 falls at a high speed. If the drone body 1 tilts during landing, the support plate 3 extends beyond the radius of the support arm 103 rotation, causing the frame enclosure formed by the second rectangular support frame 4, the four curved protective plates 301, and the first rectangular support frame 302 to first contact the ground, protecting the drone body 1 and the lift assembly 104, and preventing the side of the drone body 1 from directly hitting the ground and causing damage. In particular, the design of this frame-enclosing structure facilitates disassembly: the four wing panels 2 are threadedly connected to the first threaded holes 101 on the lower end surface of the drone body 1 via first screws 102, allowing for easy removal from the drone body 1. Simultaneously, the second rectangular support frame 4 and support panel 3 are threadedly connected to the second threaded holes 202 at the lower end of the telescopic end of the damping telescopic rod 201 via second screws 5, also allowing for easy removal from the damping telescopic rod 201. This design not only improves the landing safety of the drone body 1 but also facilitates user disassembly and installation as needed, increasing flexibility and convenience.
