Figure 1 As shown, the system includes a dual-engine throwing device for an unmanned aerial vehicle, a control module and a power supply module.

[0021] Among them, the unmanned aerial vehicle dual-launch throwing device is fixedly connected to the external fuselage of the unmanned aerial vehicle, and the unmanned aerial vehicle dual-launch throwing device is used to cooperate with the unmanned aerial vehicle to achieve dual-launch throwing of the object to be thrown.

[0022] The control module is fixedly arranged inside the unmanned aerial vehicle, and is electrically connected to the unmanned aerial vehicle dual-launch throwing device, and is used to send control instructions to the unmanned aerial vehicle dual-launch throwing device. At the same time, the control module has certain instruction or program input and storage functions. The user can input multiple different instructions or programs to the control module based on specific usage conditions. The control module stores these instructions and programs, and can output control instructions to the unmanned aerial vehicle and the unmanned aerial vehicle dual-launch throwing device based on these instructions and programs when in use.

[0023] The power supply module is fixedly arranged inside the unmanned aerial vehicle and is electrically connected to the unmanned aerial vehicle dual-launch throwing device and the control module respectively. The power supply module is used to provide driving power for the unmanned aerial vehicle and the unmanned aerial vehicle dual-launch throwing device.

[0024] In an embodiment of the present application, the dual-launch throwing device of the unmanned aerial vehicle includes a throwing mechanism and a throwing servo.

[0025] The throwing mechanism is fixedly connected to the external fuselage of the unmanned aerial vehicle, and the throwing servo is fixedly connected to the throwing mechanism. Specifically, the throwing mechanism is fixedly connected to the external fuselage of the unmanned aerial vehicle by welding, bolt connection, snap connection or other connection methods that can fix the throwing mechanism to the external fuselage of the unmanned aerial vehicle.

[0026] The power supply module includes an airborne equipment battery and a distribution board. The airborne equipment battery is electrically connected to the distribution board, and the distribution board is electrically connected to the control module and the casting servo respectively.

[0027] The power distribution board is used to distribute the power of the onboard equipment battery to the unmanned aerial vehicle and the casting servo.

[0028] Exemplarily, in an embodiment of the present application, the control module specifically implements control of the dual-launch throwing device of the unmanned aerial vehicle using a flight control computer.

[0029] Figure 5 A flowchart of a dual-launch casting method for an unmanned aerial vehicle provided in an embodiment of the present application is shown in FIG. Figure 5 As shown, the unmanned aerial vehicle dual-launch throwing method includes steps 101-106.

[0035] Step 106: Record the process of dropping the object to be thrown based on the unmanned aerial vehicle.

[0036] Figure 2 is a structural diagram of a dual-launch throwing device for an unmanned aerial vehicle provided in an embodiment of the present application, Figure 3 This is a schematic diagram of the deployment state of the dual-launch throwing device of the unmanned aerial vehicle provided in the embodiment of the present application. Figure 2 and Figure 3 As shown, the unmanned aerial vehicle dual-launch throwing device includes a throwing mechanism and a throwing servo.

[0037] The throwing mechanism includes: a support plate 1 , a mounting ear 2 , two constraint plates 4 and two ear plates 5 .

[0038] The casting servo comprises a driving member 3 .

[0039] Specifically, the structure of the dual-engine throwing device of the unmanned aerial vehicle is as follows: The support plate 1 is placed horizontally.

[0040] One end of the mounting ear 2 is fixedly arranged on the top surface of the support plate 1, and the other end thereof is fixedly connected to the external fuselage of the unmanned aerial vehicle. For example, a plurality of mounting holes are provided at one end of the mounting ear 2 away from the support plate 1, and the mounting ear 2 can be bolted to the external fuselage of the unmanned aerial vehicle through these mounting holes.

[0041] The two ear plates 5 are respectively fixedly arranged on the bottom plate surface of the support plate 1, and the two ends of the two ear plates 5 are closed inwardly along the center line away from the top of the support plate 1. Exemplarily, the ear plates 5 can be replaced based on the shape of the object to be thrown.

[0042] One end of the two constraint plates 4 is rotatably connected to one end of the corresponding ear plate 5 away from the mounting ear 2. The other end of the two constraint plates 4 is fixedly connected to one end of the corresponding ear plate 5 close to the mounting ear 2.

[0043] Specifically, in the embodiment of the present application, the constraint plate 4 is respectively connected to the corresponding ear plate 5 at one end away from the mounting ear 2 by means of the torsion spring 7 for rotation. The constraint plate 4 can rotate around the axis along the cylindrical direction of the torsion spring 7 based on the torsion spring 7.

[0044] Specifically, the structure diagram of the torsion spring 7 is as follows: Figure 4As shown, it includes a torsion spring nut 71, an elastic member 72 and a torsion arm 73.

[0045] The torsion spring 7 is a cylindrical structure, wherein a torsion spring nut 71 is sleeved on one end of the cylinder, and a limiting ring is provided at the other end of the cylinder. The outer ring diameter of the limiting ring is larger than the hole diameter at the connection between the constraint plate 4 and the ear plate 5, which is adapted to the torsion spring 7.

[0046] The elastic member 72 in the embodiment of the present application is a spring, which is spirally sleeved on the outer circumference of the cylinder, and the two ends of the elastic member 72 are respectively provided with torsion arms 73. The two ends of the torsion arms 73 are respectively in contact with the constraint plate 4 and the ear plate 5. When both ends of the constraint plate 4 and the ear plate 5 are in contact, the elastic member 72 is compressed and has elastic potential energy.

[0047] In the embodiment of the present application, two safety pins 8 are also included. The safety pins 8 are both arranged at one end of the corresponding ear plate 5 close to the driving member 3, and horizontally pass through the corresponding constraint plate 4 and the ear plate 5 in sequence along the width direction of the support plate 1 to form a limit fit.

[0048] Specifically, one end of the ear plate 5 close to the driving member 3 and one end of the constraint plate 4 close to the driving member 3 are both provided with a pin hole adapted to the diameter of the safety pin 8. When the constraint plate 4 and the ear plate 5 are buckled together, the safety pin 8 can pass through the pin holes provided on the constraint plate 4 and the ear plate 5, thereby achieving relative fixation between the constraint plate 4 and the ear plate 5.

[0049] The driving member 3 is fixedly arranged on the support plate 1 and is located between the two ear plates 5. The output end of the driving member 3 is arranged away from the top of the support plate 1 and is slidably connected to one end of the two constraint plates 4 close to the mounting ear 2 to form a limit fit.

[0050] Specifically, a steering gear installation slot along the width direction of the support plate 1 is provided between the two ear plates 5 on the support plate 1, and the upper end of the driving member 3 can extend into the steering gear installation slot and be fixedly connected to the support plate 1. The driving member 3 can also be directly fixed to the support plate 1.

[0051] In the embodiment of the present application, a limiting block 6 is fixedly provided at one end of the two constraint plates 4 close to the driving member 3, and a limiting groove 61 is provided on one side of the two limiting blocks 6 for adapting to the output end of the driving member 3. The slot length direction of the two limiting grooves 61 is consistent with the plate length direction of the support plate 1, and the openings of the two limiting grooves 61 in the slot length direction are relatively arranged. Specifically, the opening of one limiting groove 61 in the slot length direction faces forward, and the opening of the other limiting groove 61 in the slot length direction faces backward.

[0052] The opening direction of the limit groove 61 in the groove length direction is determined based on the rotation direction of the output end of the driving member 3. Specifically, the opening direction of the limit groove 61 in the groove length direction is always toward the rotation direction of the output end of the driving member 3. For example, when looking down at the unmanned aerial vehicle double-launch throwing device provided in an embodiment of the present application, if the output end of the driving member 3 rotates clockwise, the opening direction of the limit groove 61 on the left side in the groove length direction is backward, and the opening direction of the limit groove 61 on the right side in the groove length direction is forward. This is conducive to the limit groove 61 being separated from the output end of the driving member 3 when the output end of the driving member 3 rotates clockwise.

[0053] In the embodiment of the present application, two rocker arms 31 are symmetrically fixedly provided around the output end of the driving member 3, and the circumferential surfaces of the two rocker arms 31 are slidably connected to the groove walls of the corresponding limiting grooves 61 in the groove length direction to form a limiting fit.

[0054] In the embodiment of the present application, notches are formed at one end of the two ear plates 5 close to the driving member 3 , and the caliber profiles of the two notches are adapted to the volumes of the two limit blocks 6 .

[0055] The embodiment of the present application is mounted on the outside of the unmanned aerial vehicle and cooperates with the unmanned aerial vehicle to realize the double-shot throwing process of the object to be thrown. Specifically, the embodiment of the present application enables the unmanned aerial vehicle to complete the double-shot throwing of the object to be thrown through the mutual cooperation of the unmanned aerial vehicle double-shot throwing device, the control module and the power supply module. By improving the unmanned aerial vehicle double-shot throwing device, the objects to be thrown are thrown simultaneously and in pairs, solving the technical problem that the traditional throwing device can only complete the throwing operation of a single object to be thrown.

[0056] In the embodiment of the present application, the unmanned aerial vehicle dual-launch throwing device mentioned in step 105 performs a dual-launch throwing operation based on the control instruction to throw the object to be thrown to the target delivery area. The specific steps include: The driving component controls the output end of the driving component to rotate clockwise / counterclockwise according to the control instruction.

[0057] The rocker arm rotates accordingly based on the clockwise / counterclockwise rotation of the output end of the driving member, and the rocker arm is disconnected from the limit slot.

[0058] Based on the elastic potential energy of the torsion spring, the constraint plate is disconnected from the fixed connection end of the ear plate.

[0059] The objects to be thrown placed between the restraining plate and the ear plate are thrown to the target delivery area based on gravitational potential energy.

[0060] Among them, based on the elastic potential energy of the torsion spring, the fixed connection end of the constraint plate and the ear plate is disconnected, which can be specifically understood as follows: When the constraint plate is connected to both ends of the ear plate, because the torsion arms at both ends of the elastic member are in contact with one end of the constraint plate and the ear plate respectively, and the elastic member has elastic potential energy, the torsion spring has elastic potential energy.

[0061] When one end of the constraint plate fixedly connected to the ear plate is disconnected due to the disengagement of the limit block from the rocker arm, the torsion spring releases its elastic potential energy, and the end of the constraint plate away from the torsion spring can quickly disengage from the corresponding end of the ear plate.

[0062] Specifically, the detailed working principle of the driving member is as follows: The power supply module provides 5V voltage to the driver 3 based on the power distribution board, and the control module sends a PWM signal to the driver 3 to start the driver 3. After the driver 3 is started, the rocker arm 31 rotates clockwise or counterclockwise around the output end of the driver 3 (the specific rotation direction is determined based on the PWM signal), and the rotation angle is 90°~120°. When the rocker arm 31 rotates, the torsion spring 7 releases elastic potential energy, and the constraint plate 4 rotates around the cylindrical direction of the torsion spring 7. The end away from the torsion spring 7 is separated from the rocker arm 31 due to the limit block 6, and the constraint plate 4 is separated from the end of the ear plate 5 close to the mounting ear 2. The object to be thrown is separated from between the constraint plate 4 and the ear plate 5, and the throwing process is completed.

[0063] In the embodiment of the present application, a non-volatile flight control computer readable storage medium is provided inside the control module. The storage medium stores an execution program or instruction of the flight control computer, and when the execution program or instruction of the flight control computer is executed, a dual-launch throwing method of an unmanned aerial vehicle as mentioned in the embodiment can be implemented.

[0064] The above storage media include but are not limited to random access memory (RAM), read-only memory (ROM), cache, hard disk drive (HDD) or memory card. The memory can be used to store computer program instructions.

[0065] Although the present application provides method operation steps as described in the embodiments or flowcharts, more or fewer operation steps may be included based on conventional or non-creative labor. The order of steps listed in this embodiment is only one way of executing the order of many steps and does not represent the only execution order. When the actual device or client product is executed, it can be executed in sequence or in parallel according to the method shown in this embodiment or the accompanying drawings (for example, in a parallel processor or multi-threaded processing environment).

[0066] Some modules in the apparatus described in the present application can be described in the general context of computer executable instructions executed by a computer, such as program modules. Generally, program modules include routines, programs, objects, components, data structures, classes, etc. that perform specific tasks or implement specific abstract data types. The present application can also be practiced in distributed computing environments, in which tasks are performed by remote processing devices connected through a communication network. In a distributed computing environment, program modules can be located in local and remote computer storage media including storage devices.

[0067] At the same time, in an embodiment of the present application, an unmanned aerial vehicle is also provided, which can cooperate with the unmanned aerial vehicle dual-launch throwing system provided in the embodiment of the present application to realize the control of the unmanned aerial vehicle dual-launch throwing.

[0068] In addition, each functional module in each embodiment of the present invention may be integrated into one processing module, or each module may exist independently, or two or more modules may be integrated into one module.

[0069] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. All or part of this application can be used in many general or special computer system environments or configurations. For example: personal computers, server computers, handheld devices or portable devices, tablet devices, mobile communication terminals, multi-processor systems, microprocessor-based systems, programmable electronic devices, network PCs, minicomputers, mainframe computers, distributed computing environments including any of the above systems or devices, etc.

[0070] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents.
