Description

TECHNICAL FIELD

[0001] The present application relates to the field of unmanned aerial vehicle nacelles. More specifically, the present application relates to a lightweight unmanned aerial vehicle nacelle, an unmanned aerial vehicle and a method for assembling a nacelle. BACKGROUND

[0002] In recent years, unmanned aerial vehicle technology has developed rapidly and has shown great application value in aerial photography, agriculture, surveying and mapping, logistics and many other fields. With the continuous expansion and diversification of unmanned aerial vehicle application scenarios, the demand for unmanned aerial vehicle-mounted equipment is also growing. As an important component for carrying various equipment, the performance and function of the unmanned aerial vehicle nacelle have a significant impact on the efficiency and quality of the unmanned aerial vehicle's task execution. A well-designed unmanned aerial vehicle nacelle can improve the stability and safety of the equipment, thereby better meeting the needs of different industries.

[0003] With the continuous development of unmanned aerial vehicle technology, unmanned aerial vehicles carrying laser equipment for operation have gradually become a means of power line patrol. The laser equipment is fixed to the bottom of the unmanned aerial vehicle body through the unmanned aerial vehicle nacelle, and the laser equipment is moved by the unmanned aerial vehicle to conduct high-altitude patrol and foreign object removal on the power transmission line. Due to the limited battery capacity of electric unmanned aerial vehicles and the relatively large mass of laser equipment, the unmanned aerial vehicle's flight time in the air is shortened, resulting in a limited endurance time after each full charge of the unmanned aerial vehicle. To extend the endurance time of the unmanned aerial vehicle, the weight of the unmanned aerial vehicle needs to be reduced. Under the premise that the laser equipment cannot be reduced in weight, without changing the battery of the unmanned aerial vehicle, the weight of the unmanned aerial vehicle needs to be reduced by starting from the unmanned aerial vehicle nacelle.

[0004] The unmanned aerial vehicle nacelle is generally rigidly connected using complex bolt and nut assemblies. This connection method tightly fixes the nacelle and specific parts of the unmanned aerial vehicle through multiple bolts and nuts to ensure the stability of the connection. In addition, there is also a welding method that directly welds the nacelle to the corresponding structure of the unmanned aerial vehicle to achieve a firm combination. For shock absorption, the traditional method is to add rubber pads at the connection part of the nacelle and the unmanned aerial vehicle to reduce vibration transmission using the elasticity of rubber. The connection between the nacelle and the mounted equipment usually uses a conventional slot and buckle cooperation method, which involves clamping the positioning block on the equipment into the slot of the nacelle and fixing it using a buckle.

[0005] The existing technology has obvious defects. The traditional connection methods such as bolt and nut assembly connection and welding increase the overall weight of the nacelle, which is not conducive to the lightweight design of the unmanned aerial vehicle and reduces the endurance of the unmanned aerial vehicle. The effect of using rubber pads for shock absorption is limited and cannot effectively deal with the vibration problem in complex environments. The conventional slot and buckle cooperation connection method is not convenient for installing and removing equipment, which affects the work efficiency. SUMMARY

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0056] As Figures 1-3 shown, the embodiments of the present application provide a lightweight unmanned aerial vehicle nacelle, comprising:

[0057] The connecting frame 1 is used to connect with the unmanned aerial vehicle;

[0058] The damping mechanism 2 is arranged on the connecting frame 1;

[0059] The quick release mechanism 3 is arranged below the connecting frame 1 and connected with the damping mechanism 2.

[0060] In the above embodiment, the connecting frame 1 is used to connect with the unmanned aerial vehicle, the damping mechanism 2 is arranged on the connecting frame 1, and the quick release mechanism 3 is arranged below the connecting frame 1 and connected with the damping mechanism 2, so as to realize the connection of the pod with the unmanned aerial vehicle, damping and quick connection of the equipment. This is because the connecting frame 1 builds a connection bridge between the pod and the unmanned aerial vehicle, the damping mechanism 2 can reduce the influence of vibration on the pod and the equipment carried, and the quick release mechanism 3 facilitates quick installation and disassembly of the equipment carried.

[0061] Specifically, the connecting frame 1 includes two connecting rods 11 and four connecting seats. The two connecting rods 11 are arranged at intervals on the upper end of the damping mechanism 2 and can be made of light materials such as aluminum alloy. The connecting rods 11 are usually long and smooth in shape to reduce air resistance. The connecting rods 11 can also be replaced by carbon fiber rods, which have the characteristics of high strength and light weight. The four connecting seats are distributed in a rectangular shape on the upper end of the two connecting rods 11, and are arranged in two groups. The connecting seats are provided with limiting grooves 12 horizontally, and the limiting grooves 12 of the two connecting seats in the same group are connected. The connecting seat further includes a connecting piece 13, a positioning frame 14 and a limiting plate 15. The connecting piece 13 is arranged on the connecting rod 11 and can be fixed by welding or bolt connection. The material of the connecting piece 13 is the same as that of the connecting rod 11, and the shape is designed according to the connection requirements of the connecting rod 11 and the positioning frame 14, which is generally block-shaped. The positioning frame 14 is arranged vertically above the connecting piece 13 and is hinged to the connecting piece 13. The positioning frame 14 can be hinged to the connecting piece 13 by a rotating shaft, so that the positioning frame 14 can rotate around the rotating shaft to facilitate angle adjustment. The positioning frame 14 can also be connected to the connecting piece 13 by a spherical joint to realize multi-directional rotation adjustment. The limiting plate 15 is detachably connected with the positioning frame 14 and forms the limiting groove 12 together with the positioning frame 14. The limiting plate 15 can be connected with the positioning frame 14 by buckling or bolt, which is convenient for disassembly and installation. The material of the limiting plate 15 is the same as that of the positioning frame 14, and the shape is plate-shaped, which is matched with the positioning frame 14 in size. The combination of the connecting seat enables the limiting groove 12 to be adjusted and used as needed, facilitating connection with different parts of the unmanned aerial vehicle.

[0062] Specifically, as Figure 6As shown, the damping mechanism 2 includes a mounting frame, a moving plate 21, a sliding sleeve 22 and a plurality of elastic buffers 23. The mounting frame is arranged below and connected to the connecting frame 1, and includes an upper plate body 24, a lower plate body 25 and a plurality of support frames 26. The upper plate body 24 is arranged below and connected to the connecting frame 1, and can be fixed by bolts. The upper plate body 24 is generally flat, made of aluminum alloy, and the surface is treated to improve corrosion resistance. The lower plate body 25 is arranged below the upper plate body 24, and the moving plate 21 is arranged between the upper plate body 24 and the lower plate body 25. The lower plate body 25 has a notch in the middle, and the sliding sleeve 22 penetrates the notch. The shape of the lower plate body 25 is similar to that of the upper plate body 24, but the size of the notch in the middle is designed according to the size of the sliding sleeve 22. A plurality of support frames 26 are arranged between the upper plate body 24 and the lower plate body 25. The support frames 26 can be columnar or rod-shaped, made of lightweight high-strength materials such as titanium alloy, and serve to support the upper plate body 24 and the lower plate body 25 to ensure the structural stability of the mounting frame. The moving plate 21 is arranged in the mounting frame and has a rectangular flat shape. The material is similar to that of the mounting frame, and the surface is smooth, allowing flexible movement in the mounting frame. The sliding sleeve 22 is vertically arranged at the lower end of the moving plate 21, and its lower end penetrates the mounting frame and is connected to the quick release mechanism 3. The sliding sleeve 22 is generally cylindrical in shape and made of stainless steel. The surface is polished to reduce friction with the mounting frame notch. A plurality of elastic buffers 23 are evenly distributed around the sliding sleeve 22. The upper end of the elastic buffer 23 is connected to the moving plate 21, and the lower end is connected to the mounting frame. The elastic buffer 23 is a spring 37 shock absorber composed of a spring 37 and a damper. The spring 37 can be made of high-strength alloy steel, and the damper can be a hydraulic damper. Through the extension and contraction of the spring 37 and the buffering effect of the damper, the transmission of vibration is effectively reduced. The elastic buffer 23 can also be a rubber shock pad, which has good elasticity and shock absorbing performance. This combination of structures of the damping mechanism 2 can effectively buffer and absorb the vibration from the unmanned aerial vehicle, protecting the equipment carried in the pod.

[0063] Specifically, the quick release mechanism 3 is used to realize the quick connection of the pod and the carried equipment. Although the specific structure of the quick release mechanism 3 is not described in detail in the claims, in combination with the background art and actual needs, the quick release mechanism 3 can adopt the way of magnetic attraction and slot cooperation. For example, a strong magnet is arranged on the quick release mechanism 3, and an iron sheet or magnetic material is arranged at the corresponding position of the carried equipment, and the initial connection is realized by magnetic attraction. At the same time, a matching slot and a protrusion are arranged on the quick release mechanism 3 and the carried equipment respectively. When the magnetic attraction is achieved, the protrusion is inserted into the slot to further strengthen the stability of the connection. Such design makes the installation and disassembly of the carried equipment more convenient and fast.

[0064] The lightweight unmanned aerial vehicle pod of the embodiment is connected with the unmanned aerial vehicle through the connecting frame 1, the connecting frame 1 is made of light material and has a reasonable structure design, thereby reducing the overall weight and being beneficial to the lightweight design of the unmanned aerial vehicle and the improvement of the endurance capability. The damping mechanism 2 is provided with elastic buffering pieces 23 such as springs 37, which can effectively reduce the influence of vibration on the pod and the carried equipment and improve the stability and safety of the equipment. The quick release mechanism 3 adopts an innovative connection mode, which facilitates the quick installation and disassembly of the carried equipment and improves the work efficiency. Compared with the prior art, the weight, damping effect and equipment disassembly convenience are significantly improved.

[0065] Preferably, as another embodiment of the present application, as shown in Figures 4-5 The lightweight unmanned aerial vehicle pod further comprises:

[0066] The positioning block 31 is fixed on the laser equipment 4;

[0067] The quick release seat 32 is provided with a positioning groove 33 corresponding to the positioning block 31 at the lower end, and two first horizontal groove bodies 34 are oppositely arranged on the inner wall of the positioning groove 33, and the positioning block 31 is provided with two second horizontal groove bodies 35 corresponding to the two first horizontal groove bodies 34, respectively;

[0068] The limiting block 36 is slidably arranged in the first horizontal groove body 34, and a spring 37 is arranged between the limiting block 36 and the inner wall of the first horizontal groove body 34;

[0069] Two groups of fixing assemblies are arranged on the quick release seat 32;

[0070] When the positioning block 31 is not inserted into the positioning groove 33, the limiting block 36 is located in the corresponding first horizontal groove body 34; when the positioning block 31 is inserted into the positioning groove 33, the second horizontal groove body 35 is in communication with the corresponding first horizontal groove body 34, and the fixing assembly can fix the limiting block 36 in the corresponding second horizontal groove body 35.

[0071] The fixing assembly comprises:

[0072] The threaded sleeve 38 is horizontally arranged outside the quick release seat 32;

[0073] The positioning bolt 39 is coaxially arranged in the threaded sleeve 38 and horizontally extends into the corresponding first horizontal groove body 34 and passes through the corresponding spring 37, and one end of the limiting block 36 close to the positioning bolt 39 is provided with a notch corresponding to the positioning bolt 39.

[0074] In the above embodiment, when the positioning block 31 is not inserted into the positioning slot 33, the spring 37 pushes the limiting block 36 to be completely located in the first horizontal groove body 34, avoiding the parts from falling off. In the assembly process, when the positioning block 31 is inserted into the positioning slot 33, the second horizontal groove body 35 forms a continuous slide with the first horizontal groove body 34, and the operator can push the limiting block 36 along the slide to the second horizontal groove body 35 by hand or tool. At this time, the fixing assembly applies axial pressure to the limiting block 36, so that it forms an interference fit with the inner wall of the second horizontal groove body 35, thereby establishing a three-point constraint mechanism.

[0075] The quick release mechanism 3 includes a positioning block 31, a quick release seat 32, a limiting block 36, and two sets of fixing assemblies. The positioning block 31 is fixed on the laser equipment 4, which can be in the shape of a square block, and the material is selected according to the requirements of the laser equipment 4, generally metal material, and the surface is treated to improve wear resistance. The lower end of the quick release seat 32 is provided with a positioning slot 33 corresponding to the positioning block 31, and two first horizontal groove bodies 34 are oppositely arranged on the inner wall of the positioning slot 33. The positioning block 31 is provided with two second horizontal groove bodies 35 corresponding to the two first horizontal groove bodies 34, respectively. The quick release seat 32 can be made of plastic or composite material to reduce weight, and its shape is designed according to the matching requirements of the positioning block 31 and the limiting block 36, and the whole is in block structure. The limiting block 36 is slidably arranged in the first horizontal groove body 34, and the spring 37 is arranged between the limiting block 36 and the inner wall of the first horizontal groove body 34. The limiting block 36 is generally a square slide block, which is made of metal and has a smooth surface, facilitating sliding in the groove body. The spring 37 can be a compression spring 37, and its elastic coefficient is selected according to actual requirements to ensure the normal sliding and fixing of the limiting block 36. The two sets of fixing assemblies are arranged on the quick release seat 32, and each fixing assembly includes a threaded sleeve 38 and a positioning bolt 39. The threaded sleeve 38 is horizontally arranged on the outer side of the quick release seat 32, which is made of metal and has a threaded inner wall for cooperation with the positioning bolt 39. The positioning bolt 39 is coaxially arranged in the threaded sleeve 38 and horizontally extends into the corresponding first horizontal groove body 34, and passes through the corresponding spring 37. The end of the limiting block 36 close to the positioning bolt 39 is provided with a notch corresponding to the positioning bolt 39. The positioning bolt 39 can be a stainless steel bolt, and the surface is treated by zinc plating to prevent rusting.

[0076] The quick release mechanism 3 of the embodiment realizes the quick installation and disassembly of the mounted equipment through the cooperation of the positioning block 31, the limiting block 36 and the fixing assembly. When the positioning block 31 is inserted into the positioning slot 33, the limiting block 36 enters the second horizontal groove body 35 under the action of the spring 37, and then is fixed by the fixing assembly to complete the connection. When disassembling, the fixing assembly is loosened, the limiting block 36 returns to the first horizontal groove body 34 under the action of the spring 37, and the mounted equipment can be easily removed. This design not only improves the work efficiency, but also has firm and reliable connection, which is obviously improved compared with the existing technology of slot and buckle cooperation.

[0077] The unmanned aerial vehicle also comprises a body of the unmanned aerial vehicle, and further comprises the lightweight unmanned aerial vehicle pod according to any one of the above embodiments, and the connecting frame 1 is connected with the landing gear at the lower end of the body of the unmanned aerial vehicle.

[0078] In the above embodiment, the unmanned aerial vehicle comprises a body of the unmanned aerial vehicle and the lightweight unmanned aerial vehicle pod according to the above embodiment, and the connecting frame 1 is connected with the landing gear at the lower end of the body of the unmanned aerial vehicle. The body of the unmanned aerial vehicle can adopt a common multi-rotor unmanned aerial vehicle structure, and the fuselage is made of a lightweight composite material to reduce the weight. The landing gear is generally of a foldable structure and is made of aluminum alloy or carbon fiber material, and has sufficient strength and stability. The connection between the connecting frame 1 and the landing gear can be achieved by bolts or buckles to ensure the firmness of the connection.

[0079] The unmanned aerial vehicle of the embodiment is equipped with the lightweight unmanned aerial vehicle pod, and the pod adopts lightweight design and efficient shock absorption and quick release mechanism 3, thereby reducing the load of the unmanned aerial vehicle, improving the endurance, and facilitating the replacement and use of the carried equipment, so that the unmanned aerial vehicle is more flexible and efficient when performing tasks, and has better performance than the unmanned aerial vehicle carrying a traditional pod.

[0080] The application further provides an assembling method of the pod of the unmanned aerial vehicle, comprising the following steps:

[0081] S1, the positioning block 31 is inserted into the positioning groove 33 at the lower end of the quick release seat 32. In operation, a suitable tool such as tweezers or a small clamp is used to accurately place the positioning block 31 into the positioning groove 33. The operator needs to ensure that the position of the positioning block 31 is correct to avoid tilting or jamming.

[0082] S2, when the upper end of the positioning block 31 abuts against the top of the positioning groove 33, control the two limiting blocks 36 to move inwardly to be partially located in the second horizontal groove body 35. The limiting block 36 can be moved inwardly by manually pressing or using a special pushing tool to overcome the resistance of the spring 37. During the movement, the movement of the limiting block 36 is observed to ensure that it accurately enters the second horizontal groove body 35.

[0083] S3, the two limiting blocks 36 are fixed in the corresponding second horizontal groove body 35 by two groups of fixing assemblies, and the connection and fixation of the positioning block 31 and the quick release seat 32 are completed. The wrench or other tools are used to tighten the positioning bolt 39 so that the positioning bolt 39 passes through the spring 37 and abuts against the notch on the limiting block 36 to fix the limiting block 36 in the second horizontal groove body 35. The tightening process should be moderate to avoid damaging the parts due to over-tightening or causing loose connection due to over-looseness.

[0084] In this embodiment, the positioning block 31 is extended upward into the positioning groove 33 at the lower end of the quick release seat 32; when the upper end of the positioning block 31 is in contact with the top of the positioning groove 33, the two limiting blocks 36 are moved inward to be partially located in the second horizontal groove body 35; the two limiting blocks 36 are fixed in the corresponding second horizontal groove body 35 by two sets of fixing assemblies, completing the connection and fixation of the positioning block 31 and the quick release seat 32. Specifically, when the positioning block 31 is moved upward to the top of the positioning groove 33, the vertical position is limited by the groove top plane, and at this time the limiting block 36 is in the initial position of the first horizontal groove body 34. By applying a horizontal pushing force, the limiting block 36 overcomes the resistance of the spring 37 and moves along the first horizontal groove body 34 to the direction of the second horizontal groove body 35, and when the limiting block 36 partially enters the second horizontal groove body 35, a transverse mechanical constraint is formed. The fixing assembly cooperates with the positioning bolt 39 through the threaded sleeve 38 to press and fix the limiting block 36 on the inner wall of the second horizontal groove body 35, forming an irreversible mechanical locking. This process realizes the quick assembly of the positioning block 31 and the quick release seat 32 through the sequential operation of the three stages of vertical positioning, transverse limiting and rigid fixation.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent replacements of the technical solutions of the present application do not deviate from the spirit and scope of the present application, and they should be covered in the scope of the claims of the present application.
