Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to a barrel-type launching device mounted on an UAV. Background Art

[0002] The UAV aircraft sends a trigger signal to the ignition mechanism in the tube launcher through the circuit control system to achieve rapid ignition and launch of the smoke bomb. The tube launcher on the UAV is controlled by remote control of the UAV, and the smoke bomb is launched from the electronically controlled UAV, which can achieve tasks such as rapid deployment of smoke, interference with enemy vision, cover operations or signal transmission. However, when the UAV launches smoke bombs and light projectiles during flight, the smoke bomb projectiles are placed horizontally in the tube launcher, and the smoke bombs are not fixed inside the tube launcher. The UAV will make sudden stops and move quickly during flight, which will generate inertial tilting force during flight, making it easy for the smoke bomb to slide out of the tube launcher at an angle, affecting the stability of the smoke bomb projectiles. Utility Model Content

[0003] The present invention provides a barrel-type launching device based on UAV mounting, which overcomes the shortcomings described in the background technology.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A barrel-type launcher for use on drones, comprising a launch barrel, a barrel cover, a guide rail, a bracket, and a fastener. The bracket, mounted on the drone, mates with the guide rail. The fastener is disposed on the side of the guide rail, and the fastener opens and closes to secure the guide rail and the bracket. The barrel cover is fastened to one side of the launch barrel at the upper end of the guide rail.

[0006] The launching tube is provided with a fixing mechanism and a barrel body, the fixing mechanism is arranged inside the barrel body, the barrel cover is provided with a rear cover, a screw block, a connecting piece and an ignition block, the screw block and the connecting piece are arranged on both sides of the barrel body opposite to each other, and one side of the rear cover is hinged on the connecting piece, and the other side of the rear cover is opened and closed and fixed by the screw block, two ignition blocks are provided, and the two ignition blocks are arranged inside the rear cover, the wires connected to the ignition blocks extend outward through the side wall of the rear cover, and the wires extending outward from the ignition blocks are connected in series with the wires extending outward from the fixing mechanism;

[0007] When the two ignition blocks trigger the ignition position of the smoke bomb, the wire connection controls the fixing mechanism to loosen and fix the smoke bomb in the barrel body.

[0008] A preferred technical solution: The fixing mechanism is provided with a housing, a connecting ring, a motor and a rotating ring. The motor is arranged inside the housing and is connected in series with the ignition block circuit. A concave structure corresponding to the rotating ring is provided on the inner side of the connecting ring, and a ball sliding with the outer side of the rotating ring is provided in the concave structure. The circuit controls and drives the output end of the motor to engage with the outer side of the rotating ring, engaging and driving the rotating ring to rotate with the ball bearing inside the connecting ring.

[0009] A better technical solution: the rotating ring is provided with a rubber strip, a rotating ring, a blocking block, a tooth block and a movable block, the tooth block is arranged on the outside of the rotating ring, two rubber strips are provided, and the two ends of the two rubber strips are arranged between the blocking block and the rotating ring, the movable block is arranged on the outside of the blocking block, the output end of the motor is engaged with the tooth block and rotates relative to the rotating ring, when the output end of the motor is engaged with the tooth block on the outside of the movable block, the output end of the motor presses the movable block and pushes the blocking block to move inward, and causes the blocking block to stretch the rubber strip.

[0010] A better technical solution: the two sides of the blocking block are inclined. When the blocking block moves toward the central axis of the connecting ring, the top of the blocking block presses against the outside of the smoke bomb. When the output end of the motor disengages from the tooth block on the outside of the movable block, the rubber strip elastically drives the blocking block to move outward.

[0011] A preferred technical solution: The blocking block is made of rubber and is located directly above the connecting ring. When the smoke bomb is fired in the barrel body, the blocking block separates from the smoke bomb, allowing the smoke bomb to slide in the barrel body and be fired outward.

[0012] Compared with the existing technology, this technical solution has the following advantages:

[0013] In the utility model, the smoke bomb of the fixing mechanism is placed in the barrel body, and the ignition position of the smoke bomb corresponds to the ignition block. The wireless controller in the drone is remotely controlled to output a rated voltage of 12V to the ignition block, and the electric primer of the smoke bomb is stimulated by the brass bullet pin in the ignition block. The electric primer then ignites the gunpowder in the smoke bomb barrel, thereby pushing the bomb body out of the barrel body. The drone wires connect the control ignition block and the fixing mechanism, and issue an ignition control to the ignition block. When the smoke bomb is not ignited, the inner side of the fixing mechanism presses and fixes the smoke bomb in the barrel body, thereby preventing the smoke bomb from easily slipping out of the barrel body on the drone, and avoiding the smoke bomb from slipping out due to loose fixation during drone flight.

[0014] In the utility model, the drone controls the rotation of the output end of the motor through the electric wire, and the rotating ring is driven by the rotation of the motor output end. When the ignition block ignites and triggers the smoke bomb, the motor output end drives the gear block to engage and rotate, causing the rotating ring to rotate. At this time, the movable block disengages from the engagement of the motor output end, and drives the blocking block to move outward under the elastic reset of the rubber strip, so that the blocking block is separated from the support for the smoke bomb. Therefore, after the ignition block triggers the smoke bomb, the ignition block immediately triggers the ignition of the smoke bomb and launches it, preventing the smoke bomb from easily slipping out of the barrel body when the drone is flying, thereby achieving the effect of quickly detaching and launching the smoke bomb.

[0026] like Figures 1 to 6As shown, the present invention proposes a barrel-type launch device based on drone mounting, comprising a launch barrel 1, a barrel cover 2, a guide rail piece 3, a bracket 4 and a fastener 5. The bracket 4 provided on the drone is aligned with the guide rail piece 3. The fastener 5 is provided on the side of the guide rail piece 3. The opening and closing of the fastener 5 fixes the alignment of the guide rail piece 3 and the bracket 4. The barrel cover 2 is fastened to the side of the launch barrel 1 at the upper end of the guide rail piece 3.

[0027] The launching tube 1 is provided with a fixing mechanism 11 and a barrel body 12, wherein the fixing mechanism 11 is arranged inside the barrel body 12, and the barrel cover 2 is provided with a rear cover 21, a screw block 22, a connecting piece 23 and an ignition block 24, wherein the screw block 22 and the connecting piece 23 are arranged on both sides of the barrel body 12 opposite to each other, and one side of the rear cover 21 is hinged on the connecting piece 23, and the other side of the rear cover 21 is opened and closed and fixed on the screw block 22, and two ignition blocks 24 are provided, and the two ignition blocks 24 are arranged inside the rear cover 21, and the wires connected to the ignition blocks 24 extend outward through the side wall of the rear cover 21, and the wires extending outward from the ignition blocks 24 are connected in series with the wires extending outward from the fixing mechanism 11;

[0028] When the two ignition blocks 24 trigger the ignition position of the smoke bomb, the wire connection controls the fixing mechanism 11 to loosen and fix the smoke bomb in the barrel body 12.

[0029] In the present invention, the smoke bomb of the fixing mechanism 11 is placed in the barrel body 12, and the ignition position of the smoke bomb corresponds to the ignition block 24. The wireless controller in the drone is remotely controlled to connect the drone wires to control the ignition block 24 and the fixing mechanism 11, and issue an ignition control to the ignition block 24. Before the smoke bomb is ignited, the inner side of the fixing mechanism 11 presses and fixes the smoke bomb in the barrel body 12. Before ignition, the fixing mechanism 11 releases the pressing and fixing of the smoke bomb, and instantly launches the smoke bomb from the barrel body 12, preventing the smoke bomb from easily slipping out of the barrel body 12 on the drone, and avoiding the smoke bomb from slipping out due to loose fixation during drone flight.

[0030] Among them, the fixing mechanism 11 is provided with a shell 111, a connecting ring 112, a motor 113 and a rotating ring 114. The motor 113 is arranged inside the shell 111, and the motor 113 is connected in series with the ignition block 24. The inner side of the connecting ring 112 is provided with a concave structure corresponding to the rotating ring 114, and the concave structure is provided with a ball sliding with the outer side of the rotating ring 114. The circuit controls and drives the output end of the motor 113 to engage with the outer side of the rotating ring 114, engaging and driving the rotating ring 114 to rotate with the ball bearing in the connecting ring 112.

[0031] Among them, the rotating ring 114 is provided with a rubber strip 1141, a rotating ring 1142, a blocking block 1143, a tooth block 1144 and a movable block 1145. The tooth block 1144 is arranged on the outside of the rotating ring 1142. There are two rubber strips 1141. The two ends of the two rubber strips 1141 are arranged between the blocking block 1143 and the rotating ring 1142. The movable block 1145 is arranged on the outside of the blocking block 1143. The output end of the motor 113 is engaged with the tooth block 1144 and rotates the rotating ring 1142. When the output end of the motor 113 is engaged with the tooth block on the outside of the movable block 1145, the output end of the motor 113 presses the movable block 1145 and pushes the blocking block 1143 to move inward, and causes the blocking block 1143 to stretch the rubber strip 1141.

[0032] In addition, both sides of the blocking block 1143 are in an inclined state. When the blocking block 1143 moves toward the central axis of the connecting ring 112, the top of the blocking block 1143 presses against the outside of the smoke bomb. When the output end of the motor 113 disengages from the engagement with the outer tooth block of the movable block 1145, the rubber strip 1141 elastically drives the blocking block 1143 to move outward.

[0033] Furthermore, the blocking block 1143 is made of rubber and is located directly above the connecting ring 112 . When the smoke bomb is fired in the barrel body 12 , the blocking block 1143 separates from the smoke bomb, allowing the smoke bomb to slide in the barrel body 12 and be fired outward.

[0034] The ignition block 24 on the rear cover 21 is provided with a brass pin contact, which is connected to the ignition block 24 with an electric wire and outputs a 12V voltage to stimulate the electric primer of the smoke bomb, thereby creating an ignition effect. The electric primer then ignites the gunpowder in the smoke bomb barrel, thereby propelling the bomb body out of the barrel body 12.

[0035] In the present invention, the drone controls the output end of the motor 113 to rotate through the wire, and the rotating ring 114 is driven by the output end of the motor 113. At this time, the rubber strip 1141 is engaged and rotated by the output end of the motor 113, and the rotating ring 1142 rolls. When the movable block 1145 is engaged with the output end of the motor 113, the movable block 1145 is pressed inward by the output end of 113, and the blocking block 1143 fixes and supports the smoke bomb, preventing the smoke bomb from easily slipping out of the barrel body 12. When the ignition block 24 ignites and triggers the smoke bomb, The output end of the motor 113 drives the gear block 1144 to engage and rotate, causing the rotating ring 1142 to rotate. At this time, the movable block 1145 disengages from the output end of the motor 113, and drives the blocking block 1143 to move outward under the elastic reset of the rubber strip 1141, so that the blocking block 1143 is separated from the support for the smoke bomb. After the ignition block 24 triggers the smoke bomb, the ignition block 24 immediately triggers the ignition of the smoke bomb and launches it, preventing the smoke bomb from easily slipping out of the barrel body 12 when the drone is flying, thereby achieving the effect of quickly detaching and launching the smoke bomb.

[0036] The above description is merely a preferred embodiment of the present invention and therefore cannot be used to limit the scope of implementation of the present invention. In other words, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
