Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and specifically to an unmanned aerial vehicle. Background Art

[0002] As an important innovation in the modern technology field, unmanned aerial vehicles (UAVs) are increasingly becoming an indispensable auxiliary tool in many industries. UAVs integrate advanced flight control systems, high-precision sensors, GPS navigation, high-definition photography and image processing, as well as remote communication technologies, and can perform complex tasks without direct human operation. In multiple fields such as aerial surveying and mapping, environmental monitoring, agricultural plant protection, emergency rescue, logistics distribution, film shooting, and military reconnaissance, UAVs have demonstrated their unique advantages and broad application potential. Through intelligent and automated operations, UAVs not only improve the operation efficiency and accuracy but also greatly reduce the labor cost and risk, injecting new vitality and possibilities into the development of modern society.

[0003] Traditional UAVs often use simple screw connections to firmly fix two propeller blades on the outer shell of the motor rotor. Although this design is simple and easy to implement, it shows obvious limitations in the face of specific environments such as water operations. Since the propeller blades will fully unfold and directly contact the water surface after the UAV enters the water, it not only greatly increases the resistance of the UAV when traveling in the water but also seriously limits its mobility and stability, resulting in the UAV being difficult to perform effective operations or complex tasks in the water environment.

[0043] The following will describe the embodiments of the present utility model in detail with reference to the accompanying drawings.

[0044] Such as Figures 1 to 22 shown, a drone includes a fuselage 1, the fuselage 1 includes a propeller assembly 2 and a drive assembly 3 connected to the propeller assembly 2. The propeller assembly 2 includes a propeller mounting base 21 connected to the drive assembly 3 and a propeller blade 22 movably connected to the propeller mounting base 21. A locking mechanism 23 is provided on the propeller mounting base 21, and the propeller blade 22 is unfolded or folded through the locking mechanism 23;

[0045] The present utility model solves the problem that existing drones often use simple threaded connections to firmly fix two propeller blades on the outer shell of the motor rotor. When the drone enters the water, the fully unfolded propeller blades directly contact the water surface, which not only greatly increases the resistance of the drone when traveling in the water, but also seriously limits its mobility and stability, resulting in the drone being difficult to effectively operate or perform complex tasks in the water environment. By providing a locking mechanism on the propeller mounting base, the propeller blades can be folded. When the drone is operating on the water, the folded propeller blades are beneficial to reducing contact with the water surface, thereby reducing resistance and improving the mobility of the drone. In addition, when the drone is operating in the air, the propeller blades can be unfolded through the locking mechanism, and the unfolded propeller blades can provide sufficient thrust effect, enabling the drone to adapt to different operating environments.

[0046] Optionally, in some embodiments, the propeller mount 21 is directly fixed to the drive assembly 3. The propeller assembly 2 includes a pressing plate horizontally arranged above the propeller mount 21 and a propeller blade 22. The propeller mount 21 is connected to the pressing plate, and the propeller blade 22 is located between the propeller mount 21 and the pressing plate. The locking mechanism 23 includes a positioning post arranged circumferentially inside the propeller mount 21 and a vertical rotating shaft arranged vertically and penetrating the pressing plate and the propeller mount 21. The vertical rotating shaft includes a first locking portion and a second locking disc located below the first locking portion. The cross-section of the first locking portion is rectangular and the sides are chamfered. The first locking portion includes a smooth surface and a locking surface arranged offset from the smooth surface. The second locking disc is provided with locking circular grooves corresponding to the positioning posts at intervals in the circumferential direction. The positioning post is provided with positioning spherical beads matched with the locking circular grooves and a spring with one end abutted against the positioning spherical beads and the other end abutted against the inner wall of the positioning post. The end of the propeller blade 22 is provided with a clamping notch adapted to the locking surface. An articulated shaft penetrating the propeller blade 22 and hinged to the propeller blade 22 is further arranged between the pressing plate and the propeller mount 21. When the propeller blade 22 is in the unfolded state, the positioning spherical beads are clamped and matched with the locking circular grooves, and the clamping notch abuts against the locking surface, thereby fixing the unfolded state of the propeller blade 22. When it is necessary to fold the propeller blade 22, the vertical rotating shaft is rotated. The locking disc rotates to drive the locking circular grooves to rotate. The locking circular grooves are re-clamped and matched with the positioning spherical beads. At this time, the relative positions of the smooth surface and the locking surface change, and the clamping notch abuts against the smooth surface. The clamping notch does not cooperate with the smooth surface to enable the propeller blade 22 to rotate, thereby realizing the folded state of the propeller blade 22.

[0047] Further, as a preferred but non-limiting manner of the present invention, the propeller mount 21 includes a first mount 211 and a second mount 212 connected to the first mount 211. The locking mechanism 23 includes a connecting shaft 231 located between the first mount 211 and the second mount 212 and hinged to the propeller blade 22, a locking end 232 located on the second mount 212, a holding portion 233 located on the locking end 232, and a locking shaft 234 connected to the holding portion 233. The propeller blade 22 is provided with a locking groove 221 inserted and matched with the locking shaft 234. A first elastic member 91 is arranged between the outer wall of the locking shaft 234 and the inner wall of the locking end 232. When the propeller blade 22 is in the unfolded state, the locking shaft 234 is inserted into the locking groove 221, thereby fixing the unfolded state of the propeller blade 22. When it is necessary to fold the propeller blade 22, the holding portion 233 is pulled upward in the vertical direction, and the pulling force is greater than the elastic force of the first elastic member 91 so that the locking shaft 234 moves upward and disengages from the locking groove 221. At this time, the propeller blade 22 can rotate. After the propeller blade 22 rotates, the user releases the holding portion 233, the pulling force disappears, the first elastic member 91 restores elastic deformation, and the locking shaft 234 moves downward in the vertical direction and abuts against the outer wall of the propeller blade 22. The locking shaft 234 restricts the rotation of the propeller blade 22, thereby fixing the folded state of the propeller blade 22.

[0048] Specifically, when the two blades 22 are in the unfolded state, the cross-section is in a "one" shape, and when the two blades 22 are in the folded state, the cross-section is in a "two" shape.

[0049] Furthermore, the driving assembly 3 includes a driving motor and a motor housing. The driving motor is located inside the motor housing. The propeller mounting seat 21 is fixedly connected to the motor housing. When the driving motor rotates, it drives the motor housing to rotate, and the propeller mounting seat 21 rotates along with the motor housing, thereby driving the blades 22 located on the propeller mounting seat 21 to rotate synchronously.

[0050] As Figures 1 to 22 shown, the propeller mounting seat 21 includes a first mounting seat 211 and a second mounting seat 212 connected to the first mounting seat 211. The locking mechanism 23 includes a connecting shaft 231 located between the first mounting seat 211 and the second mounting seat 212 and hinged to the blade 22.

[0051] Optionally, in some embodiments, the first mounting seat 211 and the second mounting seat 212 are integrally formed.

[0052] Optionally, in some embodiments, the first mounting seat 211 and the second mounting seat 212 are snap-connected.

[0053] Furthermore, as a preferred but non-limiting manner of the present invention, the first mounting seat 211 and the second mounting seat 212 are threadedly connected.

[0054] Furthermore, the connecting shaft 231 includes a smooth portion 2311 hinged to the blade 22 and a threaded connecting portion 2312 threadedly connected to the first mounting seat 211 and located below the smooth portion 2311. The cooperation between the smooth portion 2311 and the threaded connecting portion 2312 not only ensures the smooth rotation of the blade 22 but also ensures the stability of the connection between the first mounting seat 211 and the second mounting seat 212, thereby enhancing the overall structural stability of the device.

[0055] Furthermore, the setting of the connecting shaft 231 is beneficial to providing a stable hinge point, enabling the blade 22 to smoothly transition during unfolding or folding, effectively reducing the risk of jamming during operation, and thus enhancing the safety of operation. Secondly, by providing the first mounting seat 211 and the second mounting seat 212 and setting the connecting shaft 231, the forces and torques generated during the rotation of the blade 22 can be effectively dispersed, which is beneficial to reducing the concentrated stress on a single component, thereby improving the stability and durability of the entire structure.

[0056] Optionally, in some embodiments, the cross-section of the first mounting seat 211 is rectangular.

[0057] Optionally, in some embodiments, the cross-section of the first mounting seat 211 is diamond-shaped.

[0058] Optionally, in some embodiments, the cross-section of the first mounting seat 211 is strip-shaped.

[0059] As Figures 1 to 22 The locking mechanism 23 shown includes a locking end 232 located on the second mounting seat 212, a holding portion 233 located on the locking end 232, and a locking shaft 234 connected to the holding portion 233. A locking groove 221 for plugging and mating with the locking shaft 234 is provided on the blade 22. A first elastic member 91 is provided between the outer wall of the locking shaft 234 and the inner wall of the locking end 232.

[0060] Further, the locking end 232 is located at the end of the second mounting seat 212 and is integrally formed with the second mounting seat 212.

[0061] Further, the first elastic member 91 is a spring. The first elastic member 91 is located between the outer wall of the locking shaft 234 and the inner wall of the locking end 232, which is beneficial to providing an elastic buffering function. When the locking shaft 234 is inserted into the locking groove 221, the first elastic member 91 can absorb and buffer the impact force during operation, effectively reducing the mechanical pressure on the locking shaft 234 and the locking end 232, thereby improving the durability and reliability of the system.

[0062] Optionally, in some embodiments, friction stripes are provided on the outer side wall of the holding portion 233, thereby increasing the friction force between the user's hand and the holding portion 233, which is beneficial to reducing the discomfort or fatigue caused by the user's sliding.

[0063] Optionally, in some embodiments, the holding portion 233 and the locking shaft 234 are integrally formed.

[0064] Optionally, in some embodiments, the holding portion 233 and the locking shaft 234 are threadedly connected.

[0065] Specifically, when the blade 22 is in the unfolded state, the locking shaft 234 is inserted into the locking groove 221 to fix the unfolded state of the blade 22. When it is necessary to fold the blade 22, the holding portion 233 is pulled upward in the vertical direction, and the pulling force is greater than the elastic force of the first elastic member 91 so that the locking shaft 234 moves upward and disengages from the locking groove 221. At this time, the blade 22 can rotate. After the blade 22 rotates, the user releases the holding portion 233, the pulling force disappears, the first elastic member 91 recovers its elastic deformation, the locking shaft 234 moves downward in the vertical direction and abuts against the outer side wall of the blade 22, and the locking shaft 234 restricts the rotation of the blade 22, thereby fixing the folded state of the blade 22.

[0066] As Figures 1 to 22The propeller mount 21 shown includes a third mount 213 connected to the first mount 211. An elastic locking mechanism 24 is provided between the third mount 213 and the first mount 211. The third mount 213 is detachably connected to the first mount 211 through the elastic locking mechanism 24;

[0067] Further, by providing the elastic locking mechanism 24, the user can conveniently and quickly separate the first mount 211 and the third mount 213. After the drone is used for a long time, the propeller 22 is prone to performance degradation due to wear. To prevent the drone from being damaged due to the wear of the propeller 22, the user needs to regularly maintain or replace the propeller 22 on the first mount 211. The user can quickly disassemble the first mount 211 and the third mount 213 by using the elastic locking mechanism 24, which not only improves the maintenance efficiency but also reduces the maintenance cost.

[0068] Further, a third mounting groove 2134 for plugging and mating with the first mount 211 is provided on the third mount 213. The side of the third mounting groove 2134 close to the drive assembly 3 is threadedly connected to the drive assembly 3, so that while the third mount 213 is connected to the first mount 211, the connection stability between the third mount 213 and the drive assembly 3 is improved, which is beneficial to improving the overall integration of the device.

[0069] Optionally, in some embodiments, the cross-section of the third mounting groove 2134 is circular.

[0070] Optionally, in some embodiments, the cross-section of the third mounting groove 2134 is oval.

[0071] Further, the cross-section of the third mounting groove 2134 being circular or oval is beneficial to improving the convenience and accuracy of the user in installing the propeller 22. By distinguishing the shape of the cross-section, the user can accurately identify the installation positions of the propellers 22 suitable for forward rotation or reverse rotation, ensuring that the propellers 22 are accurately installed in their respective correct positions. The setting of the anti-fooling structure not only simplifies the installation process but also effectively reduces the performance problems or safety hazards caused by misinstallation.

[0072] As Figures 1 to 22The third mounting seat 213 shown is provided with a mounting cavity 2131, a first opening 2132 communicating with the mounting cavity 2131, and a second opening 2133 communicating with the mounting cavity 2131. The elastic locking mechanism 24 includes a locking shaft 241 extending through the first opening 2132 into the mounting cavity 2131, a positioning shaft 242 located on the locking shaft 241 and extending to the outside through the second opening 2133, and a second elastic member 243. One end of the second elastic member 243 abuts against the locking shaft 241, and the other end of the second elastic member 243 abuts against the inner wall of the third mounting seat 213. The first mounting seat 211 is provided with a positioning portion 2111 that is engaged and cooperated with the positioning shaft 242;

[0073] Specifically, the first mounting seat 211 is covered on the third mounting seat 213 from top to bottom in the vertical direction. The positioning shaft 242 is engaged and cooperated with the positioning portion 2111 so that the first mounting seat 211 and the third mounting seat 213 are engaged and connected. When the user needs to disassemble the first mounting seat 211 and the third mounting seat 213, the locking shaft 241 is pushed. The locking shaft 241 drives the second elastic member 243 to be squeezed toward the middle position of the third mounting seat 213, and the positioning shaft 242 moves relatively to disengage from the positioning portion 2111, and the first mounting seat 211 and the third mounting seat 213 can be separated; similarly, when it is necessary to connect the first mounting seat 211 and the third mounting seat 213, the locking shaft 241 is pushed. The locking shaft 241 drives the positioning shaft 242 to move toward the middle of the third mounting seat 213. The first mounting seat 211 is covered on the third mounting seat 213. The locking shaft 241 is released. Under the action of the second elastic member 243 recovering its elastic deformation, the locking shaft 241 drives the positioning shaft 242 to move toward the positioning portion 2111, and the positioning shaft 242 and the positioning portion 2111 are engaged and cooperated, thereby connecting the first mounting seat 211 and the third mounting seat 213.

[0074] Further, the second elastic member 243 is a spring.

[0075] Optionally, in some embodiments, the locking shaft 241 and the positioning shaft 242 are integrally formed.

[0076] Optionally, in some embodiments, the locking shaft 241 and the positioning shaft 242 are threadedly connected.

[0077] Optionally, in some embodiments, the locking shaft 241 and the positioning shaft 242 are snap-connected.

[0078] Such as Figures 1 to 22The described body 1 shown includes a first antenna assembly 4 and a second antenna assembly 5. The first antenna assembly 4 is located in a first area, and the second antenna assembly 5 is located in a second area. The uppermost side of the second area is higher than the uppermost side of the first area. A connection assembly 51 is provided between the body 1 and the second antenna assembly 5, and the second antenna assembly 5 is detachably connected to the body 1 through the connection assembly 51;

[0079] Specifically, an antenna mounting base is provided below the drive assembly 3. The first antenna assembly 4 is located within the antenna mounting base. When the drone is flying in the air, the drone can receive signals using the first antenna assembly 4. When the drone is operating on water, the first antenna assembly 4 is easily submerged by the water level and thus cannot receive signals. At this time, the second antenna assembly 5 located in the second area can receive signals normally, enabling the drone to operate normally on water. The second antenna assembly 5 is detachably connected to the body 1. When the drone is flying in the air, the user can detach the second antenna assembly 5, or keep the second antenna assembly 5 installed on the body 1 all the time. When the drone needs to operate on water, just install the second antenna assembly 5 on the body 1.

[0080] Furthermore, the first antenna assembly 4 located within the antenna mounting base and the second antenna assembly 5 located on the side wall of the body 1 need to be manually installed and switched by the user. When the drone is clearly flying in the air and will not enter the water or operate close to the water surface, the drone uses the first antenna assembly 4 located within the antenna mounting base; when the drone is clearly operating on the water surface or staying on the water surface, the user needs to manually switch to the second antenna assembly 5 located on the side wall of the body 1.

[0081] Optionally, in some embodiments, the first area and the second area do not overlap in the vertical direction, and the uppermost part of the first area is located below the lowermost part of the second area.

[0082] Optionally, in some embodiments, the first area and the second area partially overlap in the vertical direction, and the uppermost part of the first area overlaps with the lowermost part of the second area.

[0083] Furthermore, the number of the first antenna assemblies 4 is several. The user can set one first antenna assembly 4 below the drive assembly 3, or can correspondingly set a first antenna assembly 4 below each drive assembly 3, or can also set the first antenna assemblies 4 below the drive assemblies 3 on the same side.

[0084] Furthermore, the second antenna assembly 5 includes a feeder 53 extending from the inside of the second antenna assembly 5 to the outside. An antenna interface 13 electrically connected to the feeder 53 is provided on the body 1, and the antenna interface 13 is connected to the feeder 53 so that the second antenna assembly 5 can receive signals.

[0085] Furthermore, the second antenna assembly 5 is symmetrically arranged on both sides of the body 1, and both the antenna interface 13 and the feeder line 53 have waterproof performance.

[0086] As Figures 1 to 22 shown, the connection assembly 51 includes a connection base 511 located on the outer wall of the body 1 and a buckle mechanism 512 located on the second antenna assembly 5 and snap-connected to the connection base 511. A buckle installation groove 52 for installing the buckle mechanism 512 is provided on the second antenna assembly 5. The buckle mechanism 512 includes a buckle pressing plate 5121, a buckle rotating shaft 5122 located on the buckle installation groove 52 and hinged to the buckle pressing plate 5121, and a third elastic member 5123. One end of the third elastic member 5123 abuts against the buckle pressing plate 5121, and the other end of the third elastic member 5123 abuts against the inner wall of the second antenna assembly 5;

[0087] Specifically, the connection base 511 is threadedly connected to the body 1. When the user needs to disassemble the second antenna assembly 5 and the connection base 511, just press above the buckle pressing plate 5121 so that the upper part of the buckle pressing plate 5121 compresses the third elastic member 5123 in the direction close to the body 1. The lower part of the buckle pressing plate 5121 swings away from the connection base 511 under the action of the buckle rotating shaft 5122, and the lower part of the buckle pressing plate 5121 is separated from the connection base 511, so that the user can take out the second antenna assembly 5 from the connection base 511; Similarly, when the user needs to install the second antenna assembly 5 on the connection base 511, press above the buckle pressing plate 5121 so that the upper part of the buckle pressing plate 5121 compresses the third elastic member 5123 in the direction close to the body 1. The lower part of the buckle pressing plate 5121 swings away from the connection base 511 under the action of the buckle rotating shaft 5122. When the second antenna assembly 5 is completely placed into the connection base 511, release the upper part of the buckle pressing plate 5121, and the third elastic member 5123 restores its elastic deformation to drive the upper part of the buckle pressing plate 5121 to reset in the direction away from the connection base 511. The lower part of the buckle pressing plate 5121 swings towards the connection base 511 under the action of the buckle rotating shaft 5122, and the lower part of the buckle pressing plate 5121 is snap-connected to the connection base 511, so that the second antenna assembly 5 is fixed on the connection base 511.

[0088] Optionally, in some embodiments, a sliding groove is provided on the inner wall of the connection base 511, and a sliding rail slidingly connected to the sliding groove is provided on the outer wall of the second antenna assembly 5, which is beneficial to reducing the friction between the second antenna assembly 5 and the connection base 511, so that the user can insert the second antenna assembly 5 onto the connection base 511 more smoothly.

[0089] Furthermore, the third elastic member 5123 is a spring.

[0090] As Figures 1 to 22The described body 1 shown includes a battery box 6 and a battery box mounting groove 11 for accommodating the battery box 6. A first waterproof sealing ring 12 is provided between the battery box 6 and the battery box mounting groove 11. An elastic snap component 61 and a toggle snap component 62 are provided between the battery box 6 and the body 1, so that the battery box 6 and the body 1 are detachably connected;

[0091] Specifically, the cross-section of the battery box 6 is rectangular. The number of elastic snap components 61 is two and they are symmetrically arranged on both sides of the battery box 6. The number of toggle snap components 62 is two and they are symmetrically arranged on both sides of the battery box 6. A first waterproof sealing ring 12 is provided between the battery box 6 and the battery box mounting groove 11. Through the cooperation of the elastic snap component 61 and the toggle snap component 62, it is beneficial to firmly fix the battery box 6 on the battery box mounting groove 11, thereby firmly pressing the first waterproof sealing ring 12, preventing external water from entering the inside of the drone when the drone is operating on water, and effectively ensuring the normal operation of the drone.

[0092] As Figures 1 to 22 The described elastic snap component 61 shown includes a snap member 611 located on the body 1, a pressing block 612 located on the battery box 6 and snap-connected to the snap member 611, and a fourth elastic member 613. One end of the fourth elastic member 613 abuts against the pressing block 612, and the other end of the fourth elastic member 613 abuts against the outer wall of the battery box 6;

[0093] The toggle snap component 62 includes a snap block 621 located on the body 1 and a toggle block 622 located on the battery box 6 and snap-connected to the snap block 621;

[0094] Specifically, one side of the pressing block 612 on the elastic buckle assembly 61 is extended in the direction of the buckle 611, and the buckle 611 is located on the side away from the body 1, so that the buckle 611 can limit the pressing block 612 from moving away from the body 1. When the battery box 6 needs to be taken out, the pressing block 612 is pressed so that the pressing block 612 drives the fourth elastic member 613 to be squeezed toward the side close to the body 1. At this time, a space for the battery box 6 to move upward is provided between the pressing block 612 and the buckle 611. At the same time, the toggle block 622 on the buckle assembly 62 is buckled and connected with the buckle block 621. At this time, the toggle block 622 needs to be toggled to separate the buckle block 621 and the toggle block 622, and the battery box 6 is removed. It can be taken out from the battery box installation slot 11; similarly, when the battery box 6 needs to be installed, the pressing blocks 612 on both sides are pressed at the same time, and the pressing blocks 612 on both sides drive the fourth elastic member 613 to be squeezed toward the inner wall of the battery box 6, so that there is space between the pressing blocks 612 on both sides and the buckle 611, and the battery box 6 is accommodated in the battery box installation slot 11, and the pressing blocks 612 on both sides are released. The fourth elastic member 613 restores its elastic deformation, thereby squeezing the pressing blocks 612 on both sides toward the buckle 611, and the pressing blocks 612 and the buckle 611 are buckled together. At the same time, the toggle blocks 622 on both sides are toggled to make the toggle blocks 622 on both sides buckle together with the buckle blocks 621, and the installation of the battery box 6 is completed.

[0095] Furthermore, a second slide groove 6221 is provided on the toggle block 622, and a second slide rail 63 slidably connected to the second slide groove 6221 is provided on the battery box 6, which is beneficial to reducing the friction between the toggle block 622 and the battery box 6 so that the toggle block 622 can slide smoothly on the battery box 6; secondly, the sliding cooperation between the second slide groove 6221 and the second slide rail 63 effectively prevents the toggle block 622 from detaching from the battery box 6, which is beneficial to improving the stability of the device.

[0096] Furthermore, a pressing block installation groove is provided inside the pressing block 612, and a pressing block installation column extending toward the inner wall of the battery box 6 is provided on the pressing block installation groove. The fourth elastic member 613 is a spring and is sleeved on the outer wall of the pressing block installation column.

[0097] like Figures 1 to 22 The body 1 shown includes a pan-tilt assembly 7, a cover 71 covering the surface of the pan-tilt assembly 7, and a pan-tilt mounting seat 72 hinged to the pan-tilt assembly 7, a second waterproof sealing ring 73 is provided between the cover 71 and the pan-tilt assembly 7, and a waterproof sealing member is provided between the pan-tilt mounting seat 72 and the pan-tilt assembly 7;

[0098] Furthermore, by setting up the gimbal component 7, the drone can have multiple shooting functions such as timed shooting, time-lapse shooting, panoramic shooting, etc. During the flight of the drone, the gimbal component 7 can automatically adjust the direction and angle of the camera to keep the picture stable and smooth, which is beneficial to improving the shooting effect of the drone.

[0099] Furthermore, by providing a surface cover 71 on the surface of the gimbal assembly 7, and providing a second waterproof sealing ring 73 between the gimbal assembly 7 and the surface cover 71, the drone can be used for shooting in humid, rainy, or even underwater environments, thereby ensuring the normal operation of the gimbal assembly 7 and effectively extending the service life of the device.

[0100] Furthermore, the gimbal mounting seat 72 and the gimbal assembly 7 are hinged so that the gimbal assembly 7 can rotate accordingly to adjust the shooting angle. The waterproof seal is a sealant. A wiring area for laying wires is provided between the gimbal mounting seat 72 and the gimbal assembly 7 to ensure that the gimbal assembly 7 can operate normally. At the same time, sealant is poured into the wiring area to effectively prevent external water from entering the wiring area, which is beneficial to improving the overall stability of the device.

[0101] The implementation method of Example 1 is as follows:

[0102] The propeller mounting seat 21 includes a first mounting seat 211 and a second mounting seat 212 connected to the first mounting seat 211. The locking mechanism 23 includes a connecting shaft 231 located between the first mounting seat 211 and the second mounting seat 212 and hinged to the blade 22. The locking mechanism 23 includes a locking end 232 located on the second mounting seat 212, a gripping portion 233 located on the locking end 232, and a locking shaft 234 connected to the gripping portion 233. The blade 22 is provided with a locking groove 221 that is plugged into and matched with the locking shaft 234. A first elastic member 91 is provided between the outer wall of the locking shaft 234 and the inner wall of the locking end 232. When the blade 22 is in an unfolded state, the locking shaft 234 is inserted into the locking groove 221 to fix the unfolded state of the blade 22. When the blade 22 needs to be folded, the gripping portion 233 is pulled upward in the vertical direction. , the pulling force is greater than the elastic force of the first elastic member 91 so that the locking shaft 234 moves upward and disengages from the locking groove 221. At this time, the blade 22 can rotate. After the blade 22 rotates, the user releases the grip 233, the pulling force disappears, the first elastic member 91 restores its elastic deformation, and the locking shaft 234 moves downward in the vertical direction and abuts against the outer wall of the blade 22. The locking shaft 234 limits the rotation of the blade 22, thereby fixing the folded state of the blade 22, which effectively solves the problem that the existing drones often use a simple threaded connection to firmly fix the two blades on the outer casing of the motor rotor. When the drone enters the water, the fully unfolded blades directly contact the water surface, which not only greatly increases the resistance of the drone in the water, but also severely limits its maneuverability and stability, making it difficult for the drone to achieve effective operations or perform complex tasks in an aquatic environment.

[0103] The implementation manner of Embodiment 2 is as follows:

[0104] The difference between Embodiment 2 and Embodiment 1 lies in that: the propeller mount 21 further includes a third mount 213, an elastic locking mechanism 24 is provided between the third mount 213 and the first mount 211, the third mount 213 is provided with a mounting cavity 2131, a first opening 2132 communicating with the mounting cavity 2131, and a second opening 2133 communicating with the mounting cavity 2131. The elastic locking mechanism 24 includes a locking shaft 241 extending into the mounting cavity 2131 through the first opening 2132, a clamping shaft 242 located on the locking shaft 241 and extending to the outside through the second opening 2133, and a second elastic member 243. One end of the second elastic member 243 abuts against the locking shaft 241, and the other end of the second elastic member 243 abuts against the inner wall of the third mount 213. The first mount 211 is provided with a clamping portion 2111 that is engaged with the clamping shaft 242. When the user needs to disassemble the first mount 211 and the third mount 213, the locking shaft 241 is pushed, and the locking shaft 241 drives the second elastic member 243 to be squeezed towards the middle position of the third mount 213, and the clamping shaft 242 moves relatively to disengage from the clamping portion 2111, so that the first mount 211 and the third mount 213 can be separated; similarly, when the first mount 211 and the third mount 213 need to be connected, the locking shaft 241 is pushed, and the locking shaft 241 drives the clamping shaft 242 to move towards the middle of the third mount 213. The first mount 211 covers the third mount 213. The locking shaft 241 is released, and under the action of the second elastic member 243 recovering its elastic deformation, the locking shaft 241 drives the clamping shaft 242 to move towards the clamping portion 2111, and the clamping shaft 242 and the clamping portion 2111 are engaged, so as to connect the first mount 211 and the third mount 213. The user can quickly disassemble the first mount 211 and the third mount 213 by using the elastic locking mechanism 24, which not only improves the maintenance efficiency but also reduces the maintenance cost.
