Description

Technical Field

[0001] The present invention relates to the technical field of drone bombing, and in particular to a drone bombing device and a control method. Background Art

[0002] Drone bomb-dropping technology plays an important role in many fields such as military, security, agriculture, and environmental protection.

[0003] The drones equipped with the bomb pod need to have a certain load capacity and endurance, while ensuring flight stability and reliability. Common types of drones include multi-rotor drones and fixed-wing drones. The configuration of the drone includes the flight control system, power system, communication system, etc. These configurations need to meet the requirements of the bomb pod.

[0004] The structural design of the pod needs to take into account factors such as the weight, volume, and shape of the payload to ensure that the pod can be stably mounted under the drone and can be separated smoothly during release. The release mechanism needs to be fast, accurate, and reliable. Common release mechanisms include electronic release and mechanical release. Safety design is the key point to ensure that the pod will not cause harm to ground personnel or equipment during the release process.

[0005] The mounting methods usually include hanging and mounting. The fixing method needs to ensure that the connection between the pod and the drone is firm and reliable to prevent it from falling off or being damaged during flight.

[0006] Traditional drone-mounted bomb-dropping devices have problems such as unstable installation and delivery failure, which affects the flight stability of the drone, reduces the accuracy of bombing, and may even cause safety hazards.

[0007] During the launch process, it is necessary to ensure that the connection mechanism between the pod and the drone can be quickly separated without causing damage to the drone. At the same time, it is also necessary to prevent the pod from falling off or being damaged during the mounting process. Summary of the invention

[0008] In order to solve the problems of existing drone bombing technology, the present invention provides a drone bombing device and control method. The following technical solutions are adopted:

[0009] A drone bombing device, wherein the top of a mounting connection part is mounted on a load part of an unmanned aerial vehicle, the drone bombing device comprises a bomb body fixing device, a bombing actuator and a bombing controller, the bomb body fixing device comprises a shell, a bullet locking belt, a bullet locking belt mounting assembly and a bomb body fixing claw assembly, the top of the shell is mounted on the bottom of the mounting connection part, one end of the bullet locking belt is detachably mounted on one side of the bottom of the shell, and the other end is hung on the other side of the bottom of the shell through the bullet locking belt mounting assembly, the top of the bullet body fixing claw assembly is detachably mounted on the bottom of the shell, a bomb body restraining space is formed between the bottom of the bomb body fixing claw assembly and the bullet locking belt, and the bomb body restraining space is used to restrain the bomb to be dropped;

[0010] The bombing actuator is installed in the shell, and is used to drive the bullet-locking belt mounting assembly to make the bullet-locking belt slide down to complete the bombing action. The bombing controller controls the execution action of the bombing actuator.

[0011] By adopting the above technical solution, in the initial state, the bomb controller controls the locking belt mounting assembly to be in a locked state through the bomb actuator, and places the projectile to be released in the projectile restraint space formed between the bottom of the projectile fixing claw assembly and the locking belt. The projectile to be released is a grenade, a flash bomb, a blast bomb, etc. The safety grip of the projectile to be released faces downward, and then the locking belt is tightened to the projectile. The locking belt is hung on the other side of the bottom of the shell through the locking belt mounting assembly, and the elastic force of the locking belt completes the locking of the projectile to be released.

[0012] The unmanned aerial vehicle is started. After the unmanned aerial vehicle flies to the destination, the bombing controller determines the target position. The target position can be determined visually or through the interactive bombing command of the flight control system of the unmanned aerial vehicle. The bombing controller sends a signal to control the bombing actuator to drive the locking belt mounting component to move so that the locking belt slides down to complete the bombing action. Under the gravity of the projectile to be released, the locking belt opens, and the projectile falls freely, completing the bombing mission;

[0013] The unmanned aerial vehicle can be loaded with ammunition quickly, conveniently and safely, and can drop bombs reliably and accurately. The device is light in weight and high in strength, and can effectively reduce the weight of the dropping mechanism.

[0014] Optionally, the bullet locking belt mounting assembly includes a movable hanging ring of the bullet locking belt, a bomb safety hook, a safety hook damper and a bullet fixing and releasing hook. The bullet safety hook is rotatably mounted on the shell body through a rotating shaft. One end of the movable hanging ring of the bullet locking belt is connected and mounted on the bullet locking belt. The safety hook damper is mounted on the inner wall of the shell body and resists the rotating shaft of the bomb safety hook to keep the position of the bomb safety hook unchanged. The bomb fixing and releasing hook is connected to the driving shaft of the bomb actuator through the rotating shaft. The bomb fixing and releasing hook is arranged side by side with the bomb safety hook. When in the bomb hanging state, the bomb fixing and releasing hook and the hook of the bomb safety hook simultaneously hang the movable hanging ring of the bullet locking belt upwards.

[0015] Optionally, the safety hook damper is a spring column.

[0016] Optionally, guide slopes are provided on the backs of the bomb safety hook and the bomb fixing and releasing hook.

[0017] By adopting the above technical solution, in the initial state, the bomb controller controls the bomb fixing and releasing hook to face upwards through the bomb actuator, and the bomb safety hook is manually turned upwards. After the projectile to be dropped is fixed, the unmanned aerial vehicle is started. Before takeoff, the bomb safety hook is manually turned downwards to complete the operation of opening the safety, and the unmanned aerial vehicle takes off. When bombing is required, the bomb controller controls the bomb fixing and releasing hook to face downwards through the bomb actuator. Since the backs of the bomb safety hook and the bomb fixing and releasing hook are both provided with guiding inclined surfaces, the movable hanging ring of the locking belt has no force support. Under the gravity of the projectile to be dropped, the locking belt is opened, and the projectile falls freely, completing a bombing mission.

[0018] During the process of loading and removing the safety pin, it is ensured that the projectile will not fall off accidentally. The safety is opened before the UAV takes off to ensure the safety of the operator.

[0019] Optionally, the projectile fixing claw assembly includes a pair of projectile fixing claws, the tops of the pair of projectile fixing claws are detachably mounted on the bottom of the shell, the bottoms of the pair of projectile fixing claws are respectively provided with grooves, and the grooves of the pair of projectile fixing claws respectively clamp the outer wall of the projectile to be launched.

[0020] Optionally, the elastic body fixing claw assembly further includes a pair of buffer pads, and the pair of buffer pads are respectively detachably mounted at the grooves of the pair of elastic body fixing claws.

[0021] By adopting the above technical solution, the buffer pad can be made of rubber material, and the cooperation of a pair of projectile fixing claws and a pair of buffer pads, plus a flexible bullet locking belt, can make the outer wall of the projectile to be launched be clamped in a flexible range, reducing the risk of false triggering.

[0022] Optionally, the bombing actuator is a servo, and the driving shaft of the bombing actuator is connected to the bomb fixing and releasing hook through a rotating shaft. When executing the bombing action, the bombing actuator drives the bomb fixing and releasing hook to rotate 180° downward to complete the bombing action.

[0023] By adopting the above technical solution, the servo can complete the specified rotation angle under command, and can achieve stable mounting and bombing control.

[0024] Optionally, the bomb controller includes a camera assembly, a visual analysis module and a control chip. The camera assembly is mounted on the shell with the camera assembly facing downward. The visual analysis module is communicatively connected with the camera assembly, and analyzes the target position through the visual image captured by the interactive camera assembly. When the visual features of the target are successfully matched from the captured visual image data, a bomb target confirmation signal is exchanged with the control chip. The control chip is communicatively connected with the bomb actuator, and controls the execution action of the bomb actuator.

[0025] By adopting the above technical solution, the bombing control of the bombing controller can be in a variety of confirmation forms. For example, the ground control center can send control instructions wirelessly, or a visual analysis module can be used to analyze whether the picture taken by the camera component matches the target visual features. The specific method of matching the target visual features can be a mature visual feature matching algorithm. The control chip can control the action of the servo according to the instructions to complete the automatic bombing operation.

[0026] A method for controlling bombing of a drone, using a bombing device of a drone to realize the mounting and bombing control of a bomb body to be dropped, comprises the following steps:

[0027] Step 1, installing the top of the mounting connection part on the load part of the unmanned aerial vehicle;

[0028] Step 2, remove the movable hanging ring of the bullet-locking belt, confirm that the bomb-dropping safety hook and the bomb-dropping fixing and releasing hook are in an upward state, place the projectile to be dropped on the bullet-locking belt, and then hang the movable hanging ring of the bullet-locking belt on the bomb-dropping safety hook and the bomb-dropping fixing and releasing hook;

[0029] Step 3, start the unmanned aerial vehicle, input the target position parameters into the flight control system of the unmanned aerial vehicle, and rotate the bomb safety hook before the unmanned aerial vehicle takes off so that the bomb safety hook faces downward;

[0030] Step 4: The unmanned aerial vehicle takes off and flies above the target position according to the target position parameters. When the visual analysis module determines that the captured visual image data matches the target visual features successfully, it exchanges a bomb target confirmation signal with the control chip. The control chip controls the bomb actuator to execute the bombing action. The actuator drives the bomb fixing and releasing hook downward, and the active hanging ring of the locking belt slides off the guide slope of the bomb safety hook and the bomb fixing and releasing hook;

[0031] Step 5: Wait for the bomb to fall freely under the action of gravity, completing the bombing mission.

[0032] Optionally, in step 4, the bomb dropping action refers to the control chip controlling the driving axis of the bomb actuator to rotate 180°.

[0033] In summary, the present invention includes at least one of the following beneficial technical effects:

[0034] The present invention can provide a bomb-dropping device and a control method for an unmanned aerial vehicle. In an initial state, a bomb-dropping fixing and releasing hook faces upward, and a bomb-dropping safety hook is manually turned upward. After the bomb body to be dropped is fixed, the unmanned aerial vehicle is started. Before taking off, the bomb-dropping safety hook is manually turned downward to complete the operation of opening the safety hook. The unmanned aerial vehicle takes off. When bombing is required, a bomb-dropping controller controls the bomb-dropping fixing and releasing hook to face downward through a bomb-dropping actuator. Since the backs of the bomb-dropping safety hook and the bomb-dropping fixing and releasing hook are both provided with guiding inclined surfaces, the movable hanging ring of the locking belt has no force support. Under the gravity of the bomb body to be dropped, the locking belt is opened, and the bomb body falls freely, completing a bomb-dropping task.

[0035] The drone can be loaded with ammunition quickly, conveniently and safely, and can drop bombs reliably and accurately. It is also lightweight and high in strength, effectively reducing the weight of the dropping mechanism.

[0036] The bomb-dropping device has a safety mechanism, which ensures that the projectile will not fall off accidentally during the loading and safety pin pulling process. The safety is opened before the UAV takes off to ensure the safety of the operator. BRIEF DESCRIPTION OF THE DRAWINGS
