Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a detachable protective device for protecting the radar detection device of a UAV, which achieves efficient protection through a lightweight spherical protective shell and a multi-level buffer structure. Background Technology

[0002] With the widespread application of drones in military reconnaissance, disaster relief, agricultural surveying and other fields, the radar detection devices they carry often face threats from complex environments. For example, when flying at low altitudes, drones are prone to collisions with obstacles such as tree branches and buildings; during emergency landings, the radar devices may be damaged due to excessive impact.

[0003] In existing technologies, the following solutions are mainly used for radar protection of drones:

[0004] Fixed metal shield: The metal shield is fixed to the frame by welding or riveting. While this type of structure provides basic protection, it is not removable, making maintenance difficult, and its weight affects the drone's endurance.

[0005] Foam buffer layer: Foam material is wrapped around the outside of the radar device to absorb impact. However, foam material is prone to aging, and its buffering effect decreases significantly after long-term use, and it cannot withstand impacts from sharp objects.

[0006] Folding protective frame: The protective frame is unfolded and folded through a hinge structure. Although this solution is easy to store, the mechanical structure is complex, the failure rate is high, and the cushioning capacity is limited.

[0007] In summary, existing protective devices have the following shortcomings:

[0008] Non-removable design: Maintenance and replacement of radar devices require disassembly of the entire unit, which is inefficient;

[0009] Single buffer mechanism: Relying on a single material or structure to absorb impact, it cannot cope with multi-directional impacts;

[0010] The conflict between weight and strength: lightweight materials (such as plastics) lack sufficient strength, while high-strength materials (such as metals) increase the load on the fuselage.

[0011] Based on this, this utility model proposes a detachable protective device with a lightweight spherical protective shell as its core. Through a multi-level buffer design of a rigid annular protective ring, a buffer circular strip, and a spring, it takes into account both lightweight and high-strength protection requirements. Summary of the Invention

[0012] To address the problems of non-removable protective devices, poor buffering effect, and excessive weight in existing technologies, this utility model provides a UAV radar protection device. It achieves rapid assembly and disassembly through modular design and utilizes a multi-level buffer structure to disperse impact force, significantly improving the safety of the radar device.

[0013] To solve the above-mentioned technical problems, the technical solution proposed in this application is as follows:

[0014] A radar protection device for unmanned aerial vehicles (UAVs) includes a lightweight spherical protective shell, a rigid annular protective ring, a buffer circular strip, and connecting components.

[0015] The connecting assembly includes a mounting connecting block, a detachable connecting rod, and a limiting rod; the mounting connecting block is fixed to the bottom of the UAV frame and connected to a rigid annular protective ring via the detachable connecting rod; a buffer circular strip is connected to the inner side of the rigid annular protective ring via the limiting rod, and a lightweight spherical protective shell is fixedly connected to the bottom of the buffer circular strip; a buffer spring is sleeved on the outer side of the limiting rod, and the two ends of the buffer spring abut against the rigid annular protective ring and the buffer circular strip, respectively.

[0016] Furthermore, a limiting hole is provided on the mounting connecting block, and the detachable connecting rod passes through the limiting hole and is threadedly connected to the hard annular protective ring.

[0017] Furthermore, one end of the limiting rod is welded to the inner side of the rigid annular protective ring, and the other end extends to the inner side of the buffer circular strip and is fixed.

[0018] Furthermore, the frame is equipped with a flight controller, a propeller on the side, landing gear at the bottom, and a camera at one end.

[0019] Furthermore, a radar is installed inside the lightweight spherical protective shell.

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

[0021] This utility model's UAV radar protection device significantly enhances impact resistance through the synergistic effect of a lightweight spherical protective shell and a multi-level buffer structure: the outer shell is made of carbon fiber with a surface designed with anti-collision textures to disperse external impact forces; internally, an elastic buffer layer and spring structure absorb horizontal and vertical impacts, preventing damage to the radar device. The modular design utilizes detachable connecting components for quick assembly and disassembly, eliminating the need to disassemble the entire unit for maintenance, greatly improving efficiency. The overall structure strikes a balance between lightweight and high strength, reducing the load on the fuselage while enhancing adaptability to complex environments. This device effectively addresses risks such as collisions and falls, extends the radar's lifespan, reduces maintenance costs, and is suitable for various fields including military, rescue, and surveying.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] The following will be combined with the appendix Figure 1-2 The specific implementation method of the UAV radar protection device of this utility model is described in detail.

[0027] The UAV radar protection device of this utility model is mainly used to protect the radar on the UAV and prevent it from being damaged by collisions, impacts and other factors during flight. The following will describe in detail its various components and installation and working process.

[0028] like Figure 1 As shown, the frame 1 of the drone is the main supporting structure of the entire drone. The flight controller is fixedly installed inside the frame 1. The flight controller is the core control component for the drone's flight, used to control parameters such as flight attitude, heading, and altitude. A propeller 3 is mounted on the side of the frame 1. The propeller 3 rotates under the drive of motors, providing lift and flight propulsion for the drone. The landing gear 4 is connected to the bottom of the frame 1. The landing gear 4 provides support during takeoff and landing, protecting the drone from ground impacts. In addition, a camera 2 is installed at one end of the frame 1. The camera 2 can be used to capture images or videos to meet different application needs.

[0029] The protective device mainly includes a lightweight spherical protective shell 6, a rigid annular protective ring 5, a buffer circular strip 11, and connecting components.

[0030] See Figure 2The connecting assembly includes a mounting block 7, a detachable connecting rod 8, and a limiting rod 12. The mounting block 7 is fixed to the bottom of the UAV frame 1, specifically through welding, bolting, or other methods to ensure a secure fixation. A limiting hole 9 is provided on the mounting block 7, through which the detachable connecting rod 8 passes and is threadedly connected to the rigid annular protective ring 5. Figure 2 The image shows the disassembled state, with the detachable connecting rod 8 not passing through the limiting hole 9. This design allows for easy installation and disassembly of the protective device, facilitating maintenance and replacement.

[0031] The inner side of the rigid annular protective ring 5 is connected to the buffer circular strip 11 via a limiting rod 12. One end of the limiting rod 12 is welded to the inner side of the rigid annular protective ring 5, and the other end extends to the inner side of the buffer circular strip 11 and is fixed to ensure the stability of the connection between the two. A buffer spring 10 is sleeved on the outer side of the limiting rod 12, with its two ends abutting against the rigid annular protective ring 5 and the buffer circular strip 11, respectively. When the protective device is subjected to external impact, the buffer spring 10 can buffer and dampen the shock, reducing the impact force on the internal radar.

[0032] The bottom of the buffer circular strip 11 is fixedly connected to a lightweight spherical protective shell 6, which houses the radar. The lightweight spherical protective shell 6 can be made of lightweight plastics, composite materials, etc., to protect the radar while minimizing the impact on the UAV's flight performance.

[0033] During flight, the drone may encounter various obstacles or suffer accidental collisions. When an external impact force acts on the lightweight spherical protective shell 6, the impact force is transmitted to the buffer circular strip 11. After being impacted, the buffer circular strip 11 moves along the direction of the limiting rod 12, compressing the buffer spring 10. The buffer spring 10 absorbs and disperses the impact force during compression, thereby reducing the impact force transmitted to the radar and protecting the radar from damage.

[0034] Meanwhile, the rigid annular protective ring 5 provides further support and protection, preventing excessive deformation of the protective device due to excessive impact. The connection between the detachable connecting rod 8 and the mounting connecting block 7 ensures a stable connection between the protective device and the UAV frame 1, guaranteeing that the protective device will not loosen or fall off during flight.

[0035] In summary, the UAV radar protection device of this utility model, through reasonable structural design and buffering and shock absorption measures, can effectively protect the radar on the UAV, improve the radar's service life and reliability, and facilitate installation and maintenance.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
