Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a blade binding device for an unmanned aerial vehicle. Background Technique

[0002] An unmanned aerial vehicle is an unpiloted aircraft controlled by a radio remote control device and a self - contained program control device. It is divided into two categories: military and civilian. The former can perform tasks such as reconnaissance and surveillance, and fire strikes, while the latter is used in many fields such as agricultural plant protection and power line inspection. It usually consists of a fuselage, wings, a power system, a flight control system, a navigation system, a communication system, and a mission payload. The power system provides power, the flight control system controls flight, the navigation system ensures accurate positioning, the communication system realizes data transmission and command interaction, and it can fly manually or autonomously. It has the advantages of flexibility, high efficiency, low cost, and low risk, and its performance is constantly improving, and the application scope is continuously expanding.

[0003] At present, with the rapid development of unmanned aerial vehicle technology, the effective fixation and protection of unmanned aerial vehicle blades have become an important research topic. The traditional methods of fixing unmanned aerial vehicle blades have significant limitations and deficiencies.

[0004] Common fixing means, such as simply using ordinary ropes for bundling, are not only extremely cumbersome in operation, requiring a lot of time and effort to complete the bundling process, but also because the ropes lack sufficient rigidity and stability, they cannot provide uniform and reliable binding force, making it difficult to ensure that the blades can maintain a stable fixed state under various transportation and storage conditions.

[0005] Some more complex fixing devices may have improved fixing effects, but they have problems such as complex structures and numerous components. This not only increases the weight of the device itself, which is not conducive to the overall lightweight design of the unmanned aerial vehicle, but also requires operators to have high skills and patience during the installation and disassembly processes. The operation steps are cumbersome, time - consuming, and labor - intensive. For scenarios where unmanned aerial vehicles need to be used frequently, such complex fixing and disassembly processes greatly reduce work efficiency.

[0006] More importantly, due to the large differences in the models of unmanned aerial vehicles and the sizes and shapes of the blades, traditional fixing devices often lack effective adjustment functions. They can usually only adapt to blades of specific sizes and shapes, and cannot provide good fixing effects for blades of other sizes and models. This means that when facing diverse unmanned aerial vehicle models, users may need to purchase multiple different specifications of fixing devices, increasing the usage cost and management difficulty.

[0007] In addition, in practical applications, when a drone needs to be used, the disassembly process of the traditional fixed structure is often complex and time-consuming, which may lead to delays in operation timing. Especially in some emergency situations, such as rescue, monitoring and other scenarios that require quick response, the excessive disassembly time may have an adverse impact on the execution of the task. At the same time, the complex disassembly process may also increase the risk of misoperation by the operator, thereby causing damage to the drone and the propeller blades.

[0008] Therefore, we propose a propeller blade bundler for a drone. Summary of the Utility Model

[0009] The purpose of the present utility model is to solve the disadvantages existing in the prior art. The existing bundlers have poor versatility, and the disassembly and installation are relatively cumbersome.

[0010] In order to achieve the above purpose, the present utility model adopts the following technical solutions:

[0011] A propeller blade bundler for a drone, comprising a fixed base structure. A locking belt adjusting structure is provided on the top of the fixed base structure. Quick connection structures are connected to the two side walls of the fixed base structure. The quick connection structures can be quickly disassembled and fixed with the fixed base structure, thereby facilitating operation and achieving the purpose of quick response. The locking belt adjusting structure can adjust the quick connection structures, thereby realizing the fixation of different propeller blades and having strong versatility.

[0012] Preferably, the fixed base structure includes a base body. Connecting cavities are opened on the two side walls of the base body. Connecting holes are opened on the front and back sides of the two connecting cavities.

[0013] Preferably, the locking belt adjusting structure includes a mounting plate. Winding grooves are opened on the two side walls of the mounting plate. Winding rods are fixed on the two winding grooves.

[0014] Preferably, the quick connection structure includes two structural bodies. Two mounting grooves are opened inside the two structural bodies. A number of sliding rails are fixedly connected to the inner side walls of the four mounting grooves and located on both sides.

[0015] Preferably, sliders are slidably connected to a number of the sliding rails. Connecting plates are fixedly connected between the a number of sliders. Fixed rods are fixedly connected to the outer sides of the four connecting plates. Pressing arcs are integrally formed on the outer sides of the four fixed rods.

[0016] Preferably, a number of compression springs are fixedly connected to the inner side walls of the four connecting plates. A locking belt body is fixedly connected between the two structural bodies.

[0017] Preferably, the quick connection structure is connected through the connection hole between the fixing rod and the fixing base structure to form a fixation. The locking belt body of the quick connection structure can be wound around the winding rod of the locking belt adjustment structure, thereby changing the length of the locking belt body to achieve the purpose of fastening.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] 1. The adjustable design of the locking belt body of the quick connection structure enables the device to adapt to various sizes and shapes of drone propellers. Whether it is the wide propellers of large drones or the slender propellers of small drones, the fixing effect can be achieved firmly and fittingly by flexibly adjusting the binding belt, which greatly improves the versatility of the propeller binder and reduces the cost and trouble of equipping multiple fixing devices due to the difference in propeller sizes.

[0020] For example, when facing propellers of different drone models, there is no need to replace the propeller binder. Simply adjusting the length and tightness of the binding belt can complete a firm fixation, saving time and resources.

[0021] 2. The quick-release design of the quick connection structure and the fixing base structure greatly shortens the fixing and loosening time of the drone propeller. When the drone needs to be used, the propeller binder can be quickly disassembled, enabling the drone to quickly enter the flight state. When storing and transporting, the propeller can be quickly fixed, improving the operation efficiency.

[0022] For example, in emergency tasks or scenarios where drones are frequently used, the quick-release structure can significantly reduce the preparation time, ensuring that the drone can be promptly put into work or properly stored, enhancing the continuity and convenience of work.

[0032] Embodiment 1

[0033] As Figures 1-4As shown in the figure, the utility model provides a technical solution: a drone blade bundling device, which includes a fixed base structure 1. A locking belt adjusting structure 2 is provided on the top of the fixed base structure 1. Quick connection structures 3 are connected to the two side walls of the fixed base structure 1. The quick connection structures 3 can be quickly disassembled and fixed with the fixed base structure 1, which is convenient for operation and achieves the purpose of quick response. The locking belt adjusting structure 2 can adjust the quick connection structures 3, so as to fix different blades, and has strong versatility.

[0034] The adjustable design of the locking belt body 39 of the quick connection structure 3 enables this device to adapt to various sizes and shapes of drone blades. Whether it is the wide blades of large drones or the slender blades of small drones, the binding belt can be flexibly adjusted to achieve a stable and fitting fixing effect. This greatly improves the versatility of the bundling device and reduces the cost and trouble of equipping multiple fixing devices due to blade size differences.

[0035] For example, when facing different models of drone blades, there is no need to replace the bundling device. Simply adjusting the length and tightness of the binding belt can complete a firm fixation, saving time and resources.

[0036] The quick-disassembly design of the quick connection structure 3 and the fixed base structure 1 greatly shortens the time for fixing and loosening the drone blades. When the drone needs to be used, the bundling device can be quickly disassembled, enabling the drone to quickly enter the flight state. When storing and transporting, the blades can be quickly fixed, improving the operation efficiency.

[0037] For example, in emergency tasks or scenarios where drones are frequently used, the quick-disassembly structure can significantly reduce the preparation time, ensure that the drone can be quickly put into work or properly stored, and improve the continuity and convenience of work.

[0038] Embodiment 2

[0039] As Figures 1-4 shown in the figure, the utility model provides a technical solution: the fixed base structure 1 includes a base body 11. Connection cavities 12 are opened on both side walls of the base body 11, and connection holes 13 are opened on the front and back sides of the two connection cavities 12.

[0040] The locking belt adjusting structure 2 includes a mounting plate 21. Winding grooves 22 are opened on both side walls of the mounting plate 21, and winding rods 23 are fixed on the two winding grooves 22.

[0041] The quick connection structure 3 includes two structural bodies 31. Two mounting grooves 32 are opened inside the two structural bodies 31, and a number of sliding rails 33 are fixedly connected to the inner sides of the four mounting grooves 32 and on both side walls.

[0042] A slider 34 is slidably connected to each of several slide rails 33. A connecting plate 35 is fixedly connected between several sliders 34. Fixed rods 36 are fixedly connected to the outer sides of the four connecting plates 35. Pressing arc bodies 37 are integrally formed on the outer sides of the four fixed rods 36.

[0043] Several compression springs 38 are fixedly connected to the inner side walls of the four connecting plates 35. A locking belt body 39 is fixedly connected between the two structural bodies 31.

[0044] The quick connection structure 3 is connected to the connection hole 13 of the fixed base structure 1 through the fixed rod 36 to form a fixation. The locking belt body 39 of the quick connection structure 3 can be wound around the winding rod 23 of the locking belt adjustment structure 2, so as to change the length of the locking belt body 39 to achieve the purpose of fastening.

[0045] The working process of the present utility model: When using a drone blade bunching device, first, the fixed base structure 1 needs to be placed at the bottom of the drone. Then, the blades of the drone are folded. When the folding is completed, at this time, the locking belt body 39 of the quick connection structure 3 needs to be placed at the top of the drone, and the two structural bodies 31 at both ends are pulled towards the bottom, so as to fix the blades. When the fixation is completed, at this time, the redundant parts of the locking belt body 39 on both sides are respectively wound around the winding rod 23.

[0046] The specific winding steps are as follows: Fix the starting end of the locking belt body 39 close to one end of the winding rod 23. Then, wind it evenly in a spiral manner along the surface of the winding rod 23 with appropriate force or in a specific direction, and pay attention to keeping the distance between each turn approximately equal to avoid looseness or excessive overlap. After winding to a certain length or the required position, carry out the finishing. At this time, just insert the structural body 31 part into the connection cavity 12.

[0047] It should be noted that when the structural body 31 and the connection cavity 12 are connected, first, the hands need to hold the two pressing arc bodies 37. Under the action of force, the pressing arc bodies 37 will slide backward through the fixed rods 36 and the connecting plates 35. When sliding, the connecting plates 35 will slide on the slide rails 33 through the sliders 34, and the compression springs 38 will be compressed during the sliding until the pressing arc bodies 37 are pushed into the structural body 31. At this time, the whole structural body 31 can be inserted into the connection cavity 12.

[0048] After the insertion is completed, since the connection hole 13 is open, the pressing arc body 37 will be ejected out by the compression spring 38 in the absence of an object blocking, and then connected to the connection hole 13 to complete the mutual fixation.

[0049] In summary, when fixing the blade, only need to place the locking belt body 39 around the blade, and tighten it downward for fixation. Then wind the redundant locking belt body 39 around the winding rod 23. Since the blade sizes of each model are different, the required sizes for fixation are also different. Therefore, when fixing, the redundant locking belt body 39 needs to be fixedly wound around the winding rod 23, which can simultaneously form an auxiliary fixation for the blade. After the fixation is completed, only need to insert the structural body 31 into the connection cavity 12, and automatic locking will be formed. Conversely, it is very convenient during disassembly. At the same time, the structure of this application can also meet the requirements of different blades and the drone body, with strong versatility.

[0050] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
