[0059] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0060] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0061] Combination Figures 1-6 As shown, the aircraft provided in this embodiment includes a shell with an inner cavity. The inner cavity is equipped with a drive mechanism 3 and a control unit 4. The shell also includes a camera assembly 2. The camera assembly 2 has an air inlet 215, and the shell has a first air outlet 121. An airflow channel can be formed between the air inlet 215 and the first air outlet 121. Airflow enters the inner cavity from the air inlet 215, flows through the drive mechanism 3 to the control unit 4, and then exits from the first air outlet 121. During flight, the inner cavity can generate a cooling airflow. This airflow, entering the inner cavity from the air inlet 215, flowing through the drive mechanism 3 to the control unit 4, and then exiting from the first air outlet 121, facilitates the cooling of the internal components of the aircraft and removes hot air from the inner cavity. The airflow channel formed between the air inlet 215 and the first air outlet 121 significantly accelerates the cooling speed of the drive mechanism 3 and the control unit 4, improves the cooling effect, reduces the possibility of damage to the internal components of the aircraft due to overheating, and extends the service life of the aircraft.

[0062] In addition, the airflow channel formed between the air inlet 215 and the first air outlet 121 can also reduce wind resistance.

[0063] In this embodiment of the disclosure, the number of air inlets 215 is at least one, and can be set to multiple as needed.

[0064] Multiple first air outlets 121 can be provided. When two or more first air outlets 121 are provided, the two or more first air outlets 121 are spaced apart along the length of the aircraft, which further improves the heat dissipation performance of the aircraft.

[0065] In some specific embodiments, the first air outlet 121 is located at the top of the housing, allowing airflow to smoothly exit from the air inlet 215 after entering through the air inlet 215. This facilitates heat dissipation for the internal electronic components of the aircraft and reduces wind resistance. The first air outlet 121 is positioned opposite the control unit 4, which is beneficial for heat dissipation of the control unit 4. The opposite positioning of the first air outlet 121 and the control unit 4 allows airflow to enter the internal cavity from the air inlet 215, pass through the drive mechanism 3, flow to the control unit 4, and exit from the first air outlet 121. This dissipates the heat generated by the drive mechanism 3 and the control unit 4, reducing the possibility of damage to the drive mechanism 3 and the control unit 4 due to overheating and extending the service life of the aircraft.

[0066] In some specific embodiments, second air outlets 122 are provided on both sides of the shell, allowing airflow to smoothly exit from the second air outlets 122 after entering from the air inlet 215. This facilitates heat dissipation for the internal electronic components of the aircraft and reduces wind resistance. The second air outlets 122 are located on both sides of the shell corresponding to the control unit 4, so that airflow enters the inner cavity from the air inlet 215, flows through the drive mechanism 3 to the control unit 4, and exits from the second air outlets 122. During flight, a cooling airflow can be formed in the inner cavity. The airflow enters the inner cavity from the air inlet 215, flows through the drive mechanism 3 to the control unit 4, and exits from the second air outlets 122 on both sides. This facilitates heat dissipation for the internal components of the aircraft, removes hot air from the inner cavity, especially accelerates the heat dissipation speed of the control unit 4, improves the heat dissipation effect, reduces the possibility of damage to the internal components of the aircraft due to overheating, and extends the service life of the aircraft.

[0067] Optionally, the number of second air outlets 122 on each side of the shell is at least one, and can be set to multiple as needed. When two or more second air outlets 122 are provided, the two or more second air outlets 122 are spaced apart along the length of the aircraft, which further improves the heat dissipation performance of the aircraft.

[0068] When the shell is provided with a first air outlet 121 and two sets of second air outlets 122, the airflow enters from the air inlet 215 and forms three airflows, which are discharged from the first air outlet 121 and the two sets of second air outlets 122 respectively. This improves the heat dissipation effect, reduces the possibility of damage to internal components of the aircraft due to overheating, and extends the service life of the aircraft.

[0069] Combination Figure 1 , Figure 2 and Figure 6As shown, the inner cavity is equipped with a power supply structure 5, and the drive mechanism 3, control unit 4, and power supply structure 5 are arranged sequentially along the length of the shell. Both sides of the shell are provided with third air outlets 123, allowing airflow to enter from the air inlet 215 and then smoothly exit from the third air outlet 123, facilitating heat dissipation of the aircraft's internal electronic components and reducing wind resistance.

[0070] The third air outlet 123 is located on both sides of the housing corresponding to the power structure 5, so that airflow enters the inner cavity from the air inlet 215, flows to the drive mechanism 3, control unit 4 and power structure 5, and then exits from the third air outlet 123. During the flight of the aircraft, a cooling airflow can be formed in the inner cavity. The airflow enters the inner cavity from the air inlet 215, flows through the drive mechanism 3 to the control unit 4 and power structure 5, and then exits from the third air outlet 123 on both sides. This facilitates the heat dissipation of the internal components of the aircraft, removes the hot airflow in the inner cavity, especially accelerates the heat dissipation speed of the power structure 5, improves the heat dissipation effect, reduces the possibility of damage to the internal components of the aircraft due to overheating, and extends the service life of the aircraft.

[0071] Optionally, the number of third air outlets 123 on each side of the shell is at least one, and can be set to multiple as needed. When two or more third air outlets 123 are provided, the two or more third air outlets 123 are spaced apart along the length of the aircraft, which further improves the heat dissipation performance of the aircraft.

[0072] When the shell is equipped with a first air outlet 121, two sets of second air outlets 122, and two sets of third air outlets 123, the airflow entering from the air inlet 215 forms multiple airflows, which are discharged from the first air outlet 121, the two sets of second air outlets 122, and the two sets of third air outlets 123 respectively. This improves the heat dissipation effect, reduces the possibility of damage to internal components of the aircraft due to overheating, and also reduces wind resistance, thus extending the service life of the aircraft.

[0073] The power supply structure 5 may include a battery assembly. Optionally, the housing is provided with mounting holes for mounting the battery assembly, which is detachably mounted to the housing through the mounting holes for supplying power to the aircraft. The battery assembly includes a battery, which may be a rechargeable secondary battery capable of repeated charging and discharging.

[0074] Optionally, the power supply structure 5, the drive mechanism 3, the control unit 4, and the power supply structure 5 are arranged sequentially along the central axis of the length direction of the housing.

[0075] In some specific embodiments, the housing includes a nose 11 and a fuselage 12 connected to the nose 11. The nose 11 is located at the front of the aircraft and is used to point the direction of flight of the aircraft. The fuselage 12 is equipped with a drive mechanism 3, a control unit 4, and a power supply structure 5, etc. The connection between the nose 11 and the fuselage 12 forms a neck 16.

[0076] In some specific embodiments, to acquire images of the surrounding environment during the aircraft's flight, a camera assembly 2 is installed on the aircraft to capture images of the surrounding environment. The camera assembly 2 is located on the neck 16 of the aircraft, which has a mounting hole 111 for mounting the camera assembly 2. The opening of the mounting hole 111 is slightly tilted downwards, allowing the camera assembly 2 to be tilted downwards during installation, thus better capturing images of the scene below the aircraft. The camera assembly 2 includes a camera 23, which is installed in the mounting hole 111. When the aircraft lands, even if the aircraft tilts slightly forward, the camera 23 will not rub against the ground, reducing the possibility of damage to the camera 23. During flight, with the camera assembly 2 positioned at the neck 16, the camera assembly 2's field of view is not obstructed, and even changes in flight attitude, such as roll or pitch, will not affect the camera assembly 2's field of view.

[0077] The neck 16 of the aircraft is located on the fuselage 12 near the nose 11. The camera assembly 2 installed on the neck 16 will not rub against the ground when the aircraft lands, so as to avoid collisions caused by the aircraft landing and improve the service life of the camera 23.

[0078] Specifically, in combination Figures 8-13 As shown, the camera assembly 2 includes a mounting platform 21, which has an outer surface 211 with a lens hole 212. The lens hole 212 houses a camera 23 for capturing images of the surrounding environment. The camera 23 is tilted downwards during installation to better capture images of the environment below the aircraft, resulting in a more rational layout. The camera 23 can be a 360-degree panoramic camera; in some specific embodiments, it can also be a fixed-focus lens. The camera 23 can be connected to the mounting platform 21 via threaded connection, fastener connection, or adhesive bonding. Using this design, the mounting platform 21 has a simple structure, and its connection to the aircraft is detachable, facilitating installation and disassembly.

[0079] like Figure 13 As shown, the central axis of the aircraft's length direction is located on the aircraft's fuselage, and the first angle α formed between the camera's axis and the central axis of the aircraft's length direction is α. During flight, under the influence of aerodynamic torque, the fuselage 12 maintains a certain angle of elevation, namely the angle γ formed by the central axis of the aircraft's length direction and the horizontal direction L. Sensors are installed on the aircraft to acquire its attitude information. Analysis of the data collected by the sensors shows that the angle of elevation γ during flight ranges from 10° to 20°.

[0080] Combination Figure 13As shown, the angle between the camera's axis and the horizontal direction L is α-γ. Therefore, when the aircraft is flying forward, when the angle obtained by 90°-(α-γ)-β is not less than 0°, that is, when the first angle α satisfies: 40°≤α≤48°, the field of view of the camera 23 is to the left of the vertical direction H. The range of the image captured by the camera 23 is relatively wide, the image quality is clear, and it is convenient for the camera 23 to capture the environment below the aircraft.

[0081] It should be noted that the horizontal direction L mentioned above refers to the direction parallel to the ground, and the vertical direction mentioned above refers to the direction perpendicular to the ground.

[0082] Preferably, the first angle formed by the axis of camera 23 and the central axis of the aircraft along its length is set to 45°, so that the images captured by camera 23 are clearer and can better capture the environment below the aircraft.

[0083] Furthermore, the aircraft's flight altitude is set to no more than 50 meters, meaning the distance between the aircraft and the ground will not exceed 50 meters. This ensures clear images captured by camera 23 and reduces damage to the aircraft and ground objects in the event of a crash. Specifically, at a flight altitude of 50 meters, the horizontal distance covered by camera 23's field of view is between 69 and 96 meters. Within this range, the image resolution is high, allowing camera 23 to capture clear images. Moreover, within a flight altitude range of no more than 50 meters, in the event of a sudden crash or other unforeseen circumstances during flight, this limited flight altitude effectively reduces the extent of damage to ground objects and the aircraft itself caused by an accidental crash.

[0084] In some specific embodiments, a boss 213 is provided on the end of the lens hole 212 near the outer surface 211. The boss 213 extends circumferentially along the lens hole 212 and contacts the camera 23, so that the camera 23 is housed in the lens hole 212. When the aircraft lands on the ground, the camera 23 can be prevented from rubbing against the ground, which can effectively solve the problem that the camera 23 is easily damaged when the aircraft malfunctions and falls.

[0085] In some specific embodiments, the boss 213 includes an inclined surface 213a that intersects with the outer surface 211. The inclined surface 213a forms a second angle with the axis of the camera 23. The second angle β satisfies: β≥52°. This can reduce the obstruction of the boss 213 on the field of view of the camera 23, so that the camera 23 can use a 104° wide-angle lens. When the aircraft is flying at high altitude, it can obtain a larger field of view for shooting scenes.

[0086] In some specific embodiments, the mounting platform 21 is provided with an air inlet 214, which forms an air inlet 215 at one end of the outer surface 211 and communicates with the inner cavity. During flight, airflow enters the air inlet 214 from the air inlet 215 and then enters the inner cavity, carrying away the heat from the drive mechanism 3, control unit 4, or power structure 5 in the inner cavity and discharging it from the first air outlet 121, the second air outlet 122, or the third air outlet 123. This facilitates the heat dissipation of the internal components of the aircraft, expelling hot air from the inner cavity, especially accelerating the heat dissipation of the drive mechanism 3, control unit 4, and power structure 5, improving the heat dissipation effect, reducing the possibility of damage to the internal components of the aircraft due to overheating, and extending the service life of the aircraft.

[0087] In some specific embodiments, the mounting platform 21 is provided with multiple air inlets 214, which can ensure that enough air enters the inner cavity of the fuselage 12, thereby improving the heat dissipation effect of the aircraft. The multiple air inlets 214 are spaced apart and arranged around the lens hole 212, which can make the airflow enter each air inlet 214 more evenly and enter the inner cavity from the air inlet 214, thereby improving the flight stability of the aircraft.

[0088] In some specific implementations, the diameter d of the air inlet 214 satisfies: 2mm≤d≤6mm, which can improve the heat dissipation effect of the aircraft, reduce the possibility of damage to internal components due to overheating, and extend the service life of the aircraft.

[0089] Preferably, four air inlets 214 are evenly distributed around the lens hole 212. The diameter of the air inlets is about 5mm. This ensures that enough air can enter the inner cavity of the fuselage 12, while also blocking larger debris and reducing the possibility of debris entering the aircraft body and damaging the internal structure.

[0090] In some specific embodiments, the camera assembly 2 includes a protective frame 22 that fits snugly against the fuselage 12, reducing the possibility of direct impact on the fuselage 12 and protecting it. Optionally, the shape of the protective frame 22 is adapted to the fuselage 12, allowing for a better fit. This ensures that during aircraft landing, the protective frame 22 contacts the ground, preventing damage from friction between the fuselage 12 and the ground, thus extending the aircraft's service life. The protective frame 22 is connected to the mounting platform 21, and the protective frame 22 and the mounting platform 21 are an integral structure. The protective frame 22 includes a protrusion 221; combined with... Figure 2As shown, along the height direction H of the shell, the lowest point of the protrusion 221 is lower than the lowest point of the fuselage 12, so that the protrusion 221 touches the ground first when the aircraft lands. Thus, when the aircraft lands, the protrusion 221 contacts the ground first, reducing the possibility of damage to the fuselage 12 due to friction with the ground, and also playing a shock absorption role, extending the service life of the aircraft.

[0091] Optionally, the protective frame 22 can be made of polypropylene, which has high toughness and impact resistance. Optionally, the shell can be made of foamed plastic, which has good pressure resistance and cushioning.

[0092] Combination Figure 2 , Figure 9 and Figure 10 As shown, the lowest point of the protrusion 221 is lower than the lowest point of the fuselage 12, making the protrusion 221 the lowest point of the aircraft. The camera 23 is installed above the protrusion 221. When the aircraft lands, the protrusion 221 will contact the ground first. With the combined action of the protective frame 22 and the shell, the impact force on the camera 23 can be effectively buffered, protecting the camera 23 and preventing it from being damaged when the aircraft lands.

[0093] Combination Figure 6 , Figure 14 and Figure 15 As shown, the drive mechanism 3 includes a motor 31, an impeller 32, and a transmission mechanism 33. The impeller 32 is connected to the motor 31. The motor 31 includes an output shaft 311, which is arranged along the length of the housing. The impeller 32 and the transmission mechanism 33 are both mounted on the output shaft 311. The impeller 32 is positioned opposite to the control unit 4, allowing the airflow generated by the rotation of the impeller 32 to flow backward effectively and blow towards the control unit 4. In this embodiment, the housing can form an axial air duct. The airflow is accelerated after passing through the impeller 32, and the accelerated airflow provides forced convection cooling to the control unit 4 and the power supply structure 5, improving their heat dissipation performance. The impeller 32, located on the output shaft 311 of the motor 31, accelerates the airflow velocity within the cavity, improving the heat exchange efficiency of the axial air duct formed within the housing.

[0094] In some specific embodiments, the motor 31 includes a stator 312 and an outer rotor 313, with the outer rotor 313 fitted onto the stator 312. The outer rotor 313, impeller 32, and output shaft 311 are integrated into a single structure, so that when the output shaft 311 of the motor 31 rotates, it drives the impeller 32 to rotate, without excessively increasing power consumption, thus increasing the efficiency of the motor. Furthermore, it allows for increased airflow within the motor 31's internal cavity during operation, improving heat dissipation efficiency. When energized, the stator 312 of the motor 31 does not rotate, while the outer rotor 313 rotates at high speed. The drive gear fixed to the shaft of the motor 31 drives the wings to flap via the power transmission mechanism 33. The impeller 32 fixed to the shaft of the motor 31 generates airflow along the length of the casing, thereby dissipating heat for the control unit 4 and the power supply structure 5.

[0095] In some specific embodiments, there are multiple impellers 32, which are evenly spaced along the circumference of the output shaft 311. When the impellers 32 rotate, the airflow can flow through the middle of the impellers 32, which is conducive to airflow and can improve heat dissipation efficiency. While the motor 31 runs stably and smoothly, the service life of the internal components is extended.

[0096] Optionally, the transmission mechanism 33 may include a fuselage frame 15, a gear set, a connecting rod, and a swing bracket. The fuselage frame 15 may be mounted on a housing to secure the transmission mechanism 33 to the housing. The gear set may be mounted on the fuselage frame 15 and driven by a motor 31. The gear set may also be connected to the connecting rod. For example, one gear in the gear set may be connected to one end of the connecting rod, so that the rotation of the gear can drive the connecting rod to move accordingly. The other end of the connecting rod may be pivotally connected to the swing bracket, so that the swing bracket can move accordingly under the drive of the connecting rod. In addition, the swing bracket may also be pivotally connected to a fixed bracket so that the swing bracket can be supported. The wings of the aircraft may be connected to the swing bracket, so that the swing bracket drives the wings to flap up and down.

[0102] Optionally, the first PCB board and the second PCB board are electrically connected but do not touch each other. The flight control module is integrated on the first PCB board and the electronic speed control module is integrated on the second PCB board. This helps to avoid interference from other components, reduces the heat emitted by the electronic speed control module from affecting the flight control module, and improves the sensitivity of the flight control module's signal transmission.

[0103] Optionally, the third PCB board and the fourth PCB board are electrically connected but do not touch each other. The image control module is integrated on the third PCB board and the wireless communication module 44 is integrated on the fourth PCB board. This helps to avoid interference from other components and reduces the impact of the heat emitted by the image control module on the wireless communication module 44.

After processing, the processor transmits the information fed back by camera 23 to flight controller 41. Wireless communication module 44 is used to send the information received by flight controller 41 to a mobile terminal or to transmit the instructions sent by the mobile terminal to flight controller 41. Through the mobile terminal on the ground, the images captured by the aircraft during flight can be viewed directly, making it easier to determine whether the aircraft is in a normal flight operating state, thereby controlling the flight status of the aircraft.
