Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV control surface protection device. Background Technology

[0002] During transportation, storage, and handling, the protruding control surfaces (such as ailerons, rudders, and elevators) of drones are highly susceptible to damage from impacts and pressure. Control surfaces are typically thin and lightweight, and their deformation or breakage can directly affect flight performance and safety.

[0003] Currently, the protection of UAV control surfaces mainly involves the following methods:

[0004] The control surfaces are removed from the drone and packaged separately. While this method is safe, it is cumbersome, increases preparation and assembly time, and frequent disassembly and reassembly can easily wear down the connection interfaces of the control surfaces. Using materials such as foam cotton and bubble wrap to temporarily bind or wrap the control surfaces is not a reliable method of fixation. They are prone to loosening during transportation, lack effective cushioning and support, have poor resistance to compression, and offer limited protection.

[0005] Therefore, we propose a UAV control surface protection device to solve the existing problems. Utility Model Content

[0006] The purpose of this invention is to address the problems existing in the background technology by proposing a control surface protection device for unmanned aerial vehicles (UAVs).

[0007] To achieve the above objectives, this utility model provides the following technical solution: a UAV control surface protection device, comprising a base plate and a locking unit, wherein woven straps are fixedly disposed on the sides of the base plate, and a spherical airbag is fixedly disposed on the base plate, the spherical airbag protruding outward from the surface of the base plate;

[0008] The locking unit includes a buckle seat and a buckle tongue that is movably inserted into the buckle seat. Both the buckle tongue and the buckle seat are provided with a locking mechanism. The free end of the braided tape can be selectively locked to the buckle tongue and the buckle seat through the locking mechanism, so that the buckle tongues from different substrates and the buckle seat can be fastened to each other, thereby splicing together to form a protective structure covering the control surface of the UAV.

[0009] Preferably, the locking mechanism includes a latch groove formed on the latch tongue and latch seat, a main shaft rotatably mounted in the latch groove, and a locking plate fixedly disposed on the main shaft;

[0010] When the locking plate rotates to the first position, it presses against the braided strip placed in the buckle groove to achieve locking; when the locking plate rotates to the second position, it releases the braided strip to achieve unlocking.

[0011] Preferably, the braided strip is inserted into the buckle groove from below the main shaft, and the bottom of the locking plate is fixedly provided with equidistant protrusions, which are used to embed into the surface of the braided strip when locked to prevent slippage.

[0012] Preferably, an operating head is fixedly disposed on the top of the locking plate, and the operating head is tilted upward.

[0013] Preferably, the spherical airbag is an integral closed structure made of elastic material, and its interior is pre-filled with gas.

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

[0015] This utility model consists of multiple independent base plates with airbags spliced ​​together by flexible woven straps. Its wrapping size and shape can be flexibly adapted to the control surfaces of different sizes and shapes of UAVs by adjusting the number of base plates. It has strong versatility, and one set of devices can meet the protection needs of multiple UAV models.

[0016] By setting outward-protruding spherical airbags on the base plate, when the protective device covers the rudder surface and is subjected to external impact or compression, the spherical airbags can effectively absorb and disperse the impact energy through their own deformation, providing flexible and all-round buffer for the rudder surface, especially preventing local stress concentration at the edge and surface of the rudder surface, and avoiding breakage and deformation.

[0017] By combining the locking unit with the locking mechanism with the braided belt, the rapid splicing and secure locking between the base plates are achieved. The locking mechanism ensures that the braided belt will not loosen when subjected to force through the pressing action of the locking plate, thereby firmly fixing the entire protective structure to the rudder surface and preventing failure due to shaking during transportation.

[0018] Furthermore, the protruding nails on the bottom surface of the locking plate can embed into the surface of the braided tape when locked, greatly increasing the friction and providing a mechanical interlocking effect. This effectively prevents the risk of the braided tape being pulled out in a vibrating environment and ensures the ultimate reliability of the connection. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] like Figures 1-4 As shown, the present invention proposes a UAV control surface protection device, comprising a base plate 1, a locking unit 4, and a locking mechanism 5 integrated within the locking unit 4. The base plate 1 is typically made of lightweight but rigid materials such as engineering plastics or carbon fiber composites, and is preferably square in shape. Its function is to serve as the structural skeleton of the entire module, used to fix the braided strap 3 and the spherical airbag 2, and to disperse and transmit external impact force to the airbag. The spherical airbag 2 is fixedly bonded to the center of the base plate 1 and is made of elastic material to form a sealed cavity pre-filled with gas. Its core function is that when the protection device covers the control surface and is subjected to external compression or collision, the spherical airbag 2 absorbs and dissipates the impact energy through its own elastic deformation, providing a flexible, non-rigid support point for the control surface, effectively preventing the control surface from breaking or deforming due to local stress concentration.

[0028] The braided strip 3 is made of high-strength polymer fiber and has good tensile strength and wear resistance. One end of each of the four braided strips 3 is fixedly connected to the four sides of the base plate 1. The free end of the braided strip 3 is used to connect with the locking unit 4. Its length can be designed and selected according to the size of the rudder surface to be protected, providing excellent size adaptability.

[0029] The locking unit 4 is a key component for achieving rapid assembly and disassembly. The latch 402 is a housing structure with an insertion interface, and the latch tongue 401 is a sheet-like structure that can match the insertion interface of the latch 402. By inserting the latch tongue 401 from one substrate 1 into the latch 402 from another substrate 1, a clear "click" sound can be heard to complete the fastening, realizing the rapid splicing of two substrates 1. This design allows users to freely combine multiple substrates 1 into the required protection network according to the shape of the control surface to be protected.

[0030] The locking mechanism 5 is the core that ensures reliable connection and prevents loosening. It is integrated on the buckle tongue 401 and buckle seat 402 and is used to lock the free end of the braided tape 3. Its mechanism includes a buckle groove 501 opened on the component body, a main shaft 502 rotatably installed in the buckle groove 501, and a locking plate 503 fixedly installed on the main shaft 502.

[0031] The working principle of the locking mechanism 5 is a perfect combination of functionality and operability: when the locking plate 503 rotates around the main shaft 502 to the first position of pressing the buckle groove 501, it can tightly press the braided strip 3 inserted into the buckle groove 501, thereby achieving reliable locking and preventing the braided strip 3 from loosening. When adjustment or disassembly is required, the locking plate 503 is rotated to the second position of releasing the space of the buckle groove 501, and the braided strip 3 can be easily pulled out to unlock.

[0032] To cope with continuous vibration during transportation and prevent the braided belt 3 from slipping slightly, multiple spike protrusions 504 are fixedly arranged at equal intervals on the pressing surface of the locking plate 503. When the locking plate 503 is pressed, these sharp spike protrusions 504 will be deeply embedded in the surface fibers of the braided belt 3, forming a highly efficient mechanical interlock, which greatly enhances the anti-slip ability.

[0033] An operating head 505 is fixedly installed on the back of the lock plate 503. The operating head 505 is specially designed to be tilted upward, which provides an ergonomic point of force for the user's fingers. The user can easily complete the unlocking action by simply hooking the operating head 505 upward with their fingertips, which greatly improves the convenience of operation and user experience.

[0034] The workflow is as follows:

[0035] The user first arranges several base plates 1 on the control surface, ensuring that the spherical airbags 2 are in contact with the control surface. All base plates 1 are then connected longitudinally and transversely by braided straps 3 and locking units 4, ultimately forming a rigid protective network that tightly wraps around the control surface. Inside, each spherical airbag 2 provides uniform cushioning support.

[0036] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
