Abstract
Description
Technical Field
[0001] This invention relates to the field of drone auxiliary equipment technology, specifically to a drone optical launching device with a rotatable pin release mechanism. Background Technology
[0002] A drone is an aircraft that can be remotely controlled or fly autonomously. It can complete various tasks through pre-set routes, autonomous navigation systems, or remote operation.
[0003] Currently, when using drones for bombing training, the simulated bomb with a certain weight is usually manually installed on the bottom of the drone. Before the drone takes off, the simulated bomb is manually released. After the drone flies to the designated area, the simulated bomb is released and dropped into the target area.
[0004] However, the current method of using drones for bombing training has the following shortcomings:
[0005] 1. Lack of hierarchical control in trigger control: When manually controlling the throwing device to perform pin pulling and unbinding operations, existing mechanical unbinding devices mostly use a single trigger link, that is, the unbinding operation is automatically executed after the pin pulling operation is completed, which cannot realize hierarchical triggering of pin pulling and unbinding operations based on actual needs.
[0006] 2. Insufficient initial velocity of the simulated projectile: After the existing throwing device completes the unbinding operation, it only relies on the simulated projectile to perform free fall motion, that is, the initial velocity of the simulated projectile is zero. However, the triggering time of the simulated projectile is fixed, which results in a short throwing distance and the trajectory is easily disturbed by lateral airflow, leading to inaccurate landing point and poor training effect.
[0007] Therefore, there is an urgent need for a drone optical delivery device that can solve the above-mentioned technical problems. Summary of the Invention
[0008] To address the problems mentioned in the background section regarding UAV simulated projectile throwing training, this invention provides a UAV optically-sensing projectile throwing device with a rotatable pin release mechanism. The technical solution adopted by this invention is as follows:
[0009] A rotatable pin-released UAV optical-sensing throwing device for mounting and throwing simulated projectiles includes a fixing component, a pin-release component, and a mounting component; the pin-release component is disposed on one side of the fixing component, and the mounting component is disposed at the bottom of the fixing component;
[0010] The fixing component has a pneumatic chamber inside, and an air pump is installed at one end of the pneumatic chamber. The air pump is connected to a two-way air valve located at the bottom of the fixing component through the pneumatic chamber.
[0011] In one embodiment, the fixing component further includes a base, the base having an internal air pressure chamber, a suction cup and a bidirectional air valve at the bottom of the base, the suction cup being located at the center of the mounting component at the bottom of the base, the suction cup containing one bidirectional air valve, and the bottom of the base also having several bidirectional air valves centered on the suction cup.
[0012] In one embodiment, the fixing component further includes a distance sensor disposed on the bottom of the base on the opposite side away from the suction cup.
[0013] In one embodiment, the fixing assembly further includes a pneumatic cylinder and a telescopic rod. The pneumatic cylinder is nested in the pneumatic chamber. The end of the pneumatic cylinder near the air pump is connected to the pneumatic chamber. The other end of the pneumatic cylinder is slidably sleeved with the telescopic rod. The end of the telescopic rod away from the pneumatic cylinder is fixedly connected to the pin-pulling assembly.
[0014] In one embodiment, the fixing component further includes a fixing recess and a photosensitive element. The fixing recess is fixedly disposed on the top of the base, and the photosensitive element is fixedly disposed at the center of the recess on the top of the fixing recess.
[0015] In one embodiment, the top of the protruding portions on both sides of the fixing recess is fixedly connected to one end of a strap, and the other end of the strap is provided with a matching fixing buckle.
[0016] In one embodiment, the pin-pulling assembly includes a drive base, which is fixedly connected to one end of the telescopic rod. A motor is fixedly mounted on the drive base at the end away from the fixed assembly. A release element is rotatably mounted on the lower part of the drive base near the fixed assembly. The release element is fixedly connected to the motor. A pull ring is hinged to the other end of the release element.
[0017] In one embodiment, the pin-pulling assembly further includes a limiting rod and a spring. One end of the limiting rod is fixedly connected to the upper part of the drive base, and the other end of the limiting rod is slidably sleeved inside the fixing assembly. The spring is sleeved on the outer surface of the limiting rod, and one end of the spring is fixedly connected to the fixing assembly.
[0018] In one embodiment, the mounting assembly includes a locking fastener and a limiting ring. Two locking fasteners are respectively mounted opposite each other on the bottom of the base. The limiting ring is slidably sleeved on the bottom of the locking fastener. The two limiting rings are assembled to form a semi-circle facing the base.
[0019] In one embodiment, the photosensitive element is communicatively connected to the fixing component, the pin-pulling component, and the mounting component.
[0020] The beneficial effects of the UAV optically-sensing throwing device with a rotatable pin release mechanism of the present invention are as follows:
[0021] 1. By setting a photosensitive element on the top of the fixed component, setting a mounting component for the simulated projectile on the bottom of the fixed component, and setting a pin-pulling component on one side of the fixed component, the structure realizes the effect of receiving light source signals emitted by the UAV based on the photosensitive element, and then realizing the driving control of the air pump, two-way air valve, motor and locking parts according to the number of receptions. This solves the problem of lack of hierarchical control in the trigger control of current UAV bombing. Moreover, the trigger control method based on receiving light source signals by the photosensitive element also has the advantages of high precision, fast response and high adaptability.
[0022] 2. By setting a two-way air valve and suction cup at the bottom of the base, a wind wall is established based on the two-way air valve, and an initial velocity is applied to the simulated projectile. This solves the problem in traditional bombing methods where the initial velocity of the simulated projectile is insufficient, resulting in a short bombing distance and the trajectory being easily disturbed by cross airflow. It also has the advantages of high practicality and high stability. Attached Figure Description

[0031] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] like Figure 1-7 As shown, a rotatable pin-released UAV optical-sensing throwing device is used to mount a simulated projectile 4 for throwing training. The simulated projectile is a replica projectile with a certain counterweight. It includes a fixing component 1, a pin-release component 2, and a mounting component 3. The pin-release component 2 is located on one side of the fixing component 1, and the mounting component 3 is located at the bottom of the fixing component 1.
[0033] The fixing component 1 has a pneumatic chamber 103 inside, and an air pump 104 is provided at one end of the pneumatic chamber 103. The air pump 104 is connected to a two-way air valve 106 located at the bottom of the fixing component 1 based on the pneumatic chamber 103.
[0034] In this embodiment, the simulated projectile 4 is mounted on the mounting assembly 3, and a two-way air valve 106 at the bottom of the fixing assembly 1 provides secondary reinforcement to the simulated projectile 4, preventing it from accidentally falling off during the drone's flight. The air pump 104 controls and maintains the air pressure in the air pressure chamber 103. When mounting the simulated projectile 4, the air pump 104 controls the air pressure inside the air pressure chamber 103 to be lower than the external air pressure, and controls the two-way air valve 106 corresponding to the simulated projectile 4 to connect to the air pressure chamber 103, thereby fixing the simulated projectile 4 to the bottom of the fixing assembly based on air pressure. The simulated projectile is then launched. When the simulated projectile 4 is launched, the air pump 104 controls the internal air pressure of the air pressure chamber 103 to be greater than the external air pressure, and controls all the two-way air valves 106 to connect to the air pressure chamber 103. The two-way air valves 106 corresponding to the simulated projectile 4 apply force to the simulated projectile 4 under the action of air pressure, so that the simulated projectile 4 has a certain initial velocity, which increases the launching distance of the simulated projectile 4 and avoids interference during the launching process. At the same time, the other two-way air valves 106 expel the gas around the simulated projectile 4, thereby reducing the influence of the external lateral wind on the launching of the simulated projectile 4 and improving the launching accuracy of the simulated projectile 4.
[0035] In one embodiment, the fixing component 1 further includes a base 101, the base 101 having an internal air pressure chamber 103, a suction cup 105 and a bidirectional air valve 106 at the bottom of the base 101, the suction cup 105 being located at the center of the position where the mounting component 3 is installed at the bottom of the base 101, a bidirectional air valve 106 being disposed within the suction cup 105, and a plurality of bidirectional air valves 106 being disposed at the bottom of the base 101 with the suction cup 105 as the center.
[0036] In this embodiment, the bottom of the suction cup 105 is completely in contact with the outer surface of the simulated projectile 4. The air pressure in the air pressure chamber 103 is controlled by the air pump 104, so that the simulated projectile 4 is attracted and fixed to the bottom of the base 101 by the suction cup 105. When the exhaust is released by the several bidirectional air valves 106 located on the outside of the suction cup 105, an air wall is formed, which temporarily isolates the simulated projectile 4 inside the air wall from the lateral wind outside the air wall, so as to avoid the lateral wind from affecting and reducing the throwing accuracy of the simulated projectile 4.
[0037] In one embodiment, the fixing component further includes a distance sensor 107, which is disposed on the bottom of the base 101 on the opposite side away from the suction cup 105.
[0038] In this embodiment, the distance sensor 107 is used to detect the height of the throwing device above the ground. Based on the detected height, the initial velocity applied to the simulated projectile 4 can be controlled, thereby optimizing the accuracy of the throwing steps of the simulated projectile 4.
[0039] In one embodiment, the fixing component 1 further includes a pneumatic cylinder 108 and a telescopic rod 109. The pneumatic cylinder 108 is nested in the pneumatic chamber 103. The end of the pneumatic cylinder 108 near the air pump 104 is connected to the pneumatic chamber 103. The other end of the pneumatic cylinder 108 is slidably sleeved with the telescopic rod 109. The end of the telescopic rod 109 away from the pneumatic cylinder 108 is fixedly connected to the pin-pulling component 2.
[0040] In this embodiment, when both air valves 106 are closed, as the air pump 104 increases the air pressure in the air pressure chamber 103, the telescopic rod 109 in the pneumatic cylinder 108 pushes the pin-pulling assembly 2 to move away from the simulated projectile 4 under the action of air pressure, thereby realizing the pin-pulling operation.
[0041] In one embodiment, the fixing component 1 further includes a fixing recess 102 and a light-sensing element 110. The fixing recess 102 is fixedly disposed on the top of the base 101, and the light-sensing element 110 is fixedly disposed at the center of the recess on the top of the fixing recess 102.
[0042] In this embodiment, the light-sensing device 110 is used to receive the light source emitted from the bottom of the drone, and thereby control the pin-pulling and deployment operations of the simulated projectile 4 based on the number of times the light source is received.
[0043] In one embodiment, the top of the protruding portions on both sides of the fixed recess 102 is fixedly connected to one end of a strap 111, and the other end of the strap 111 is provided with a matching fixing buckle 112.
[0044] In this embodiment, the throwing device is fixedly installed on the underside of the drone using straps 111 and buckles 112.
[0045] In one embodiment, the pin-pulling assembly 2 includes a drive base 201, which is fixedly connected to one end of the telescopic rod 109. A motor 202 is fixedly installed on the drive base 201 away from the fixed assembly 1. A release element 203 is rotatably installed on the lower part of the drive base 201 near the fixed assembly 1. The release element 203 is fixedly connected to the motor 202. A pull ring 204 is hinged to the other end of the release element 203.
[0046] In this embodiment, when the telescopic rod 109 pushes the drive base 201 to move, the motor 202 simultaneously rotates the release component 203, thereby pulling out the safety pin of the simulated projectile 4 based on the pull ring 204 on the release component 203, thus realizing the rotation and release operation of the simulated projectile 4.
[0047] In one embodiment, the pin-pulling assembly 2 further includes a limiting rod 205 and a spring 206. One end of the limiting rod 205 is fixedly connected to the upper part of the drive base 201, and the other end of the limiting rod 205 is slidably sleeved inside the fixing assembly 1. The spring 206 is sleeved on the outer surface of the limiting rod 205, and one end of the spring 206 is fixedly connected to the fixing assembly 1.
[0048] In this embodiment, the limiting rod 205 is used to make a secondary connection to the drive base 201 to ensure the stability of the drive base 201. The spring 206 is used to prevent the drive base 201 from moving too fast when it approaches the base 101 after the pressure in the air pressure chamber 103 is reduced, so as to prevent an impact.
[0049] In one embodiment, the mounting component 3 includes a locking fastener 301 and a limiting ring 302. The two locking fasteners 301 are respectively installed opposite to each other on the bottom of the base 101. The limiting ring 302 is slidably sleeved on the bottom of the locking fastener 301. The two limiting rings 302 are assembled to form a semi-circle facing the base 101.
[0050] In this embodiment, the limiting rings 302 on both sides are fully extended and make contact. At this time, the fully enclosed arc formed by the locking fastener 301 and the limiting rings 302 fixes the simulated projectile 4.
[0051] In one embodiment, the photosensitive element 110 is communicatively connected to the fixing component 1, the pin-pulling component 2, and the mounting component 3, respectively.
[0052] In this embodiment, when the light sensor 110 receives a light source, it can drive and control the air pump 104, the two-way air valve 106, the motor 202, and the locking element 301 according to the number of times it receives the light.
[0053] The specific implementation of the UAV optically-sensing throwing device with a rotatable pin release mechanism according to the present invention is as follows:
[0054] Example 1: Before takeoff for the UAV drop training, the trainee operates the simulated projectile 4 to press its outer surface against the bottom of the suction cup 105 and controls the limiting ring 302 to fully extend, thereby initially fixing the simulated projectile 4 to the mounting assembly 3, and fixing the safety pin of the simulated projectile 4 to the pull ring 204. For the first time, the UAV emits a light signal to the light sensor 110 under its belly. At this time, the light sensor signal is received for the first time. The air pump 104 is controlled to reduce the air pressure in the air pressure chamber 103 and open the bidirectional air valve 106 in the suction cup 105. Thus, under the action of the atmosphere, the simulated projectile 4 is attracted and fixed under the suction cup 105, realizing the secondary fixation of the simulated projectile 4. After the secondary fixation is completed, the bidirectional air valve 106 in the suction cup 105 is closed and the operation of the air pump 104 is stopped.
[0055] Example 2: After the secondary fixation of the simulated projectile 4 is completed, the drone is driven to take off. When it reaches the target area to prepare for deployment, the drone emits a second light signal. At this time, the photosensitive element 110 receives the light signal for the second time. While keeping all bidirectional air valves 106 closed, the air pump 104 is driven to increase the air pressure in the air pressure chamber 103. At this time, the telescopic rod 109 moves away from the air pump 104 under the action of air pressure. Based on the telescopic rod 109, the pin-pulling assembly 2 moves away from the simulated projectile 4. During the movement, the drive motor 202 runs, which causes the release component 203 to drive the pull ring 204 to rotate synchronously, thereby rotating and pulling the safety pin on the simulated projectile 4 until the rotation and release operation is completed. Then the air pump 104 stops running.
[0056] Example 3: After the rotation and cancellation operation is completed, when the UAV arrives at the throwing area, the distance sensor 107 detects the height of the throwing device from the impact position, thereby determining the required initial velocity of the simulated projectile 4. The UAV emits a third light signal. At this time, the photosensitive element 110 receives the photosensitive signal for the third time, driving the air pump 104 to make the air pressure in the air pressure chamber 103 reach the air pressure value calculated based on the required initial velocity, thereby completing the pre-throw preparation work.
[0057] Example 4: When throwing training is required, the UAV emits a fourth light signal. At this time, the photosensitive element 110 receives the light signal four times, keeps the air pump 104 running, and connects all bidirectional air valves 106 except for the bidirectional air valve 106 at the suction cup 105. At this time, the remaining bidirectional air valves 106 discharge the gas in the air pressure chamber 103 to the outside, thereby forming a wind wall surrounding the simulated projectile 4 vertically by the UAV, thereby reducing the influence of the lateral wind. At the moment the wind wall is formed, the driving limit ring 302 is quickly retracted and connected to the bidirectional air valve 106 at the suction cup 105. Thus, the gas ejected from the bidirectional air valve 106 at the suction cup 105 applies a force to the simulated projectile 4, thereby applying an initial velocity to the simulated projectile 4. After the simulated projectile 4 leaves the wind wall range, all bidirectional air valves 106 are closed, and the air pump 104 is driven to reduce the air pressure in the air pressure chamber 103, thereby completely retracting the telescopic rod 109, thus completing the throwing training of the simulated projectile 4.
[0058] The present invention and its embodiments have been described above. This description is not restrictive. The accompanying drawings are only one embodiment of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the spirit of the present invention, such design should fall within the protection scope of the present invention.
