[0023] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present disclosure. In the detailed description below, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

The terms "comprise," "include," etc. used herein indicate the presence of features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0025] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0027] During the implementation of this application, it was found that the existing drones have limited functions and a narrow scope of application due to the limitations of the fuselage structure. Therefore, the embodiments of the present disclosure provide a detachable drone.

Figure 2 The figure schematically shows a perspective view of a detachable drone with the fuselage removed according to an embodiment of the present disclosure. Figure 3A perspective view of a first mating device according to an embodiment of the present disclosure is schematically shown. Figure 4 A cross-sectional view of a first mating device according to an embodiment of the present disclosure is schematically shown. Figure 5 A perspective view of a second matching device according to an embodiment of the present disclosure is schematically shown.

[0029] like Figure 1-Figure 5 As shown, the UAV may include wings 2, a fuselage 3, a quick-release device 4 and two tail struts 1 arranged at intervals. The two tail struts 1 may be arranged on both sides of the fuselage 3 relative to each other. The fuselage 3 may include a cargo hold, an unmanned boat, agricultural spraying equipment, a reconnaissance camera and other equipment suitable for different application scenarios. By providing two tail struts 1, the aerodynamic efficiency and flight stability of the UAV may be improved. The wings 2 may be located above the two tail struts 1. The quick-release device 4 may include a first mating device 41 and a second mating device 42. The first mating device 41 may be connected to the bottom of the wing 2 (such as Figure 1 The first matching device 41 can be located between the two tail struts 1. The two spaced tail struts 1 and the wings 2 can enclose a receiving space for installing the fuselage 3. The second matching device 42 can be located on the fuselage 3 (as shown). Figure 1 As shown, the second matching device 42 can be provided on the top of the fuselage 3).

[0030] Furthermore, if Figure 3 As shown, the first mating device 41 may include a movable member 411. The movable member 411 may have a first state in which the second mating device 42 is clamped to attach the fuselage 3 to the wing 2, and a second state in which the second mating device 42 is released to detach the fuselage 3 from the wing 2. In the first state, the fuselage 3 can be attached to the wing 2, allowing the drone to carry the fuselage 3 during flight. Upon arrival at the destination, the fuselage 3 can be detached from the wing 2 in the second state.

[0031] According to the disclosed embodiment, by providing a first mating device 41 at the bottom of the wing 2 and a second mating device 42 on the fuselage 3, and using the movable member 411 of the first mating device 41 to clamp the second mating device 42, the fuselage 3 can be mounted on the wing 2, allowing the drone to carry the fuselage 3 for flight. By releasing the second mating device 42 using the movable member 411, the fuselage 3 can be detached from the wing 2. This allows different types of fuselages 3 to be mounted on and removed from the drone, making the drone suitable for a wider range of usage scenarios.

[0032] like Figure 1-Figure 2 As shown, in some exemplary embodiments, the detachable UAV may further include a tail wing 6. The tail wing 6 may be connected to the vertical tail 7 of the two tail struts 1, thereby improving the flight stability of the UAV. Figure 2 As shown, the vertical tail 7 can extend obliquely backward and upward from the end of the tail strut 1.

[0033] like Figure 2 As shown, in some exemplary embodiments, the wing 2 may include a leading edge 21 of the vertical tail 7, distal from the tail boom 1, and a trailing edge 22 proximal to the vertical tail 7. The leading edge 21 and trailing edge 22 of the wing 2 may be curved, thereby delaying airflow separation and improving the lift-to-drag ratio. By increasing the width of the wing 2 and extending the lift-generating area, the drone's ability to cope with turbulence can be enhanced, further improving the drone's flight stability.

[0034] like Figure 1-Figure 2 As shown, in some exemplary embodiments, the aspect ratio of the wing 2 can be greater than 10. That is, the drone has a larger aspect ratio, which can improve the flight efficiency and structural strength of the drone.

[0035] like Figure 3-Figure 4 As shown, in some exemplary embodiments, the first matching device 41 may further include a fixing member 412 and an adjusting member 413. The movable member 411 is movably mounted on the fixing member 412. The second matching device 42 is formed with a first end of the fixing member 412 (the first end of the fixing member 412 can be characterized as the end of the fixing member 412 close to the fuselage 3, for example, Figure 3 The locking portion 414 can be configured to match the lower end of the fixing member 412 shown in the figure. That is, the locking portion 414 can be engaged with the first end of the fixing member 412. The adjusting member 413 can be provided at the second end of the fixing member 412 (the second end of the fixing member 412 can be characterized as the end of the fixing member 412 away from the fuselage 3, as shown in the figure). Figure 3 The second engaging member 42 is clamped between the upper end of the fixed member 412 (shown in FIG. 1 ) and the movable member 411. When the engaging portion 414 is engaged with the first end, the movable member 411 clamps the second engaging device 42 in response to the adjustment member 413 becoming higher. The movable member 411 releases the second engaging device 42 in response to the adjustment member 413 becoming lower.

[0036] Furthermore, the height of the adjusting member 413 is adjustable, that is, the adjusting member 413 can be raised or lowered. Since the movable member 411 can move, the adjusting member 413 is located between the second end of the fixed member 412 and the movable member 411, and the first end of the fixed member 412 is engaged with the engaging portion 414, when the adjusting member 413 is raised, the adjusting member 413 will press the movable member 411, bringing the movable member 411 closer to the second mating device 42, thereby applying a locking force to the upper surface of the second mating device 42, thereby clamping the second mating device 42. When the adjusting member 413 is lowered, the adjusting member 413 will provide more room for the movable member 411 to move away from the second mating device 42, thereby releasing the second mating device 42. The provision of the adjusting member 413 allows for relatively rapid installation or removal of the fuselage 3.

[0037] In some exemplary embodiments, the adjusting member 413 may be an airbag. The first matching device 41 also includes an air supply device 5. The air supply device 5 may be an air pump. The air supply device 5 may be remotely controlled by operation to achieve automatic installation or removal of the fuselage 3. The air supply device 5 is connected to the airbag to supply or extract air to the airbag to make the airbag taller or shorter. Of course, the adjusting member 413 may also be other components that can be heightened or shortened. For example, the adjusting member 413 may be implemented by structures such as mechanical screws or hydraulic systems. By setting the adjusting member 413 as an airbag, the weight of the drone can be reduced, and it has a faster response speed, a simple structure, and low maintenance costs, and is suitable for frequent replacement of the fuselage 3.

[0038] Furthermore, an air pressure sensor may be installed near the airbag of the first matching device 41 to control the air supply device 5 to supply or exhaust air to the airbag based on the detection result of the air pressure sensor, thereby improving the accuracy of air supply or exhaust.

[0039] like Figure 4 As shown, in some exemplary embodiments, the first matching device 41 may further include a shell 415. The shell 415 may be located on the periphery of the airbag. The fixing member 412 and the shell 415 may be fixedly connected. The upper end of the fixing member 412 may be located inside the shell 415 and connected to the shell 415 by welding, threaded connection, etc. When the air supply device 5 supplies air to the airbag, the airbag will expand due to the increase in internal pressure. The shell 415 located on the periphery of the airbag can prevent the airbag from expanding in the horizontal direction, so that the airbag can only extend in the vertical direction, that is, become taller, thereby improving the accuracy of the airbag becoming taller or shorter.

[0040] like Figure 4-Figure 5 As shown, in some exemplary embodiments, the engaging portion 414 may include a slide groove 416 and a latching slot 417. The latching slot 417 may be located above the latching slot 417. The slide groove 416 is longer than the latching slot 417. The slide groove 416 is wider than the latching slot 417. Furthermore, the first end of the fixing member 412 may include a first portion 418 and a second portion 419. The second portion 419 may be located above the first portion 418. The first portion 418 may match the shape of the slide groove 416. The second portion 419 may match the shape of the latching slot 417.

[0041] Furthermore, the entrance of the chute 416 (such as Figure 5 The width of the slide groove 416 (shown on the left side) can be relatively wide (e.g., greater than the width of the first portion 418), while the width of the slide groove 416 near the latching slot 417 can be relatively narrow (e.g., approximately the same width as the first portion 418). Due to the relatively wide width at the entrance of the slide groove 416, the slide groove 416 can facilitate rapid positioning. The fact that the width of the slide groove 416 is approximately the same as the width of the first portion 418 can represent the minimum width that allows the first portion 418 to slide within the slide groove 416.

[0042] Furthermore, during the process of installing the fuselage 3 on the wing 2, the first portion 418 can slide in the slide groove 416 until the second portion 419 moves to the locking groove 417. Because the slide groove 416 is wider than the locking groove 417, the first portion 418 matches the shape of the slide groove 416, and the second portion 419 matches the shape of the locking groove 417, that is, the first portion 418 is wider than the locking groove 417, and thus, after the second portion 419 moves to the locking groove 417, the fixed member 412 can be restricted from moving in the axial direction of the fixed member 412 relative to the second mating device 42. Because the movable member 411 is sleeved on the fixed member 412, that is, the fixed member 412 can restrict the movable member 411 from moving in the radial direction of the fixed member 412, when the movable member 411 clamps the second mating device 42, the fixed member 412 can be prevented from moving relative to the second mating device 42, thereby stably installing the fuselage 3 on the wing 2. Furthermore, when the adjusting member 413 becomes shorter, the movable member 411 releases the second matching device 42 , and the fixing member 412 can slide out from the position of the slot 417 and disengage from the second matching device 42 from the position of the slide slot 416 , thereby separating the fuselage 3 from the wing 2 .

[0043] In some exemplary embodiments, the detachable drone may further include a detection device. The detection device may be provided on the first matching device 41. The detection device may be used to detect the weight of the fuselage 3. The detection device may be a gravity sensor.

[0044] In some exemplary embodiments, the detachable drone may further include a slide rail and a brake device. The brake device and the slide rail may be provided at the bottom of the wing 2. The first matching device 41 may be provided on the slide rail, that is, the first matching device 41 may be mounted on the bottom of the wing 2 via the slide rail. The slide rail may be provided in the length direction of the wing 2 (e.g., Figure 2 The left and right direction of the wing 2 shown) and / or the width direction (as shown Figure 2 The first engaging device 41 can be connected to the first engaging device 41. The braking device can be used to drive the first engaging device 41 to move along the slide rail, that is, the braking device can drive the first engaging device 41 to move along the length and / or width of the wing 2. Therefore, after the fuselage 3 is installed, the first engaging device 41 can be driven to move based on the detection results of the detection device to adjust the center of gravity of the drone (for example, to maintain the center of gravity of the drone at the geometric center of the drone), thereby achieving the purpose of improving the stability of the drone. The braking device can be implemented by structures such as mechanical screws or a hydraulic system.

[0045] In some exemplary embodiments, a drive unit 8 and landing gear 9 may be mounted at the front end of each tail boom 1. The drive unit 8 may utilize electric or hybrid propulsion to ensure the UAV's long-duration flight capabilities, and the drive mode can be flexibly adjusted based on different mission scenarios. Each landing gear 9 may have two wheels to ensure stability during gliding.

[0046] In some exemplary embodiments, the drone may further include an environmental detection device, a positioning device, and a control device. The control device may be used to adjust the drone's flight parameters, such as flight speed and tilt angle. The control device may also be used to communicate with external devices. For example, the control device may transmit the drone's location information determined by the positioning device and external environmental information detected by the environmental detection device to the external device to facilitate user adjustment of the flight strategy. The flight strategy may include flight parameters, flight duration, and the like.

[0047] In some exemplary embodiments, the second cooperating device 42 is provided with a light source transmitter for emitting a light source. The first cooperating device 41 is provided with a light source receiver for receiving the light source. After receiving the light source, the light source receiver can convert the light signal of the light source into a light source signal in the form of an electrical signal.

[0048] The control device can determine the positional relationship between the second matching device 42 and the first matching device 41 based on the light source signal, thereby adjusting the flight parameters of the drone so that the fuselage 3 is installed on the wing 2.
