Technical Field

[0001] This invention relates to the field of jet technology, and more specifically to a reciprocating multi-functional pneumatic jet for unmanned aerial vehicles. Background Technology

[0002] In urban counter-terrorism operations, traditional drones have limited functionality and cannot meet diverse combat needs such as breaking windows, netting, tear gas dispersal, and precision strikes. Manual close-range handling poses high safety risks and low efficiency. Conventional drone jetting devices have poor compatibility, lack effective shock absorption structures, and the recoil from high-pressure jetting can easily affect flight stability. Furthermore, they have high operating thresholds and insufficient adaptability, making them difficult to adapt to the actual combat applications of grassroots troops. Therefore, there is a need for a drone jetting device that is compatible with mainstream racing drones, remotely triggered, and integrates multiple functions. To this end, a multi-functional pneumatic jetting device for drones with a reciprocating motion is proposed. Summary of the Invention

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0016] Example 1 Please see Figures 1-6 The present invention provides a reciprocating type multi-functional pneumatic jet for unmanned aerial vehicles, comprising: a mounting plate 1, an inclined slide 2 fixedly connected to the mounting plate 1, a slide groove 3 provided inside the inclined slide 2, a slider 4 slidably connected inside the slide groove 3, a buffer mechanism for assisting the slider 4 to reset installed inside the slide groove 3, and a limiting mechanism for limiting the slider 4 installed outside the inclined slide 2; a sliding plate 8 fixedly connected to the slider 4, an mounting tube 9 fixedly connected to the sliding plate 8, a gas cylinder 10 fixedly connected inside the mounting tube 9, an air inlet 23 connected to the input end of the gas cylinder 10, a sliding air valve 17 connected to the output end of the gas cylinder 10, a release mechanism for pushing the sliding air valve 17 to open and close installed outside the mounting tube 9, and a 2-point threaded connector 20 installed at the output end of the sliding air valve 17.

[0017] Specifically, the buffer mechanism includes a second insertion rod 25, which is fixedly connected to the inside of the slide groove 3. A spring 22 is sleeved on the outside of the second insertion rod 25. A first insertion rod 24 is fixedly connected to the outside of the slider 4 and is inserted into the inside of the spring 22.

[0018] Specifically, the limiting mechanism includes two threaded holes 6, both of which are located on the outside of the inclined slide 2. A limiting plate 5 is provided on the outside of the inclined slide 2. Two screws 7 are threadedly connected to the outside of the limiting plate 5, and the two screws 7 are threadedly connected to the inside of the two threaded holes 6 respectively.

[0019] Specifically, the release mechanism includes a fixed block 12, which is fixedly connected to the outside of the mounting tube 9. A servo motor 13 is mounted on the outside of the fixed block 12. The output shaft of the servo motor 13 is fixedly connected to a rotating wheel 14. A first hinge post 15 is fixedly connected to the outside of the rotating wheel 14 at a non-center position. A hinge rod 16 is hinged to the outside of the first hinge post 15. A clamp 18 is fixedly connected to the outside of the sliding air valve 17. A second hinge post 19 is fixedly connected to the outside of the clamp 18. One end of the hinge rod 16 is hinged to the second hinge post 19.

[0020] Specifically, a pressure gauge 11 is installed on the outside of the gas cylinder 10.

[0021] Specifically, the inclined slide 2 has multiple weight-reducing grooves 21 on its exterior.

[0022] Specifically, the bottom of the sliding plate 8 is slidably connected to the inclined slide 2.

[0023] In use, compressed gas is first introduced into the gas cylinder 10 through the inflation nozzle 23. The pressure gauge 11 monitors the internal pressure of the gas cylinder 10 in real time to ensure that the injection pressure meets the standard. The servo motor 13 of the drone's main control release mechanism is activated, driving the rotating wheel 14 on its output shaft to rotate. The first hinge post 15 at the non-center point of the rotating wheel 14 rotates with the rotating wheel, pushing and pulling the hinge rod 16; the hinge rod 16 drives the second hinge post 19, which pushes the sliding air valve 17 to open through the clamp 18. The compressed gas in the gas cylinder 10 is released instantly, and different specifications of nozzles are connected to the external 2-point threaded connector 20 to realize functions such as breaking windows, netting, and spraying tear gas powder.

[0024] The instantaneous jet propels the slider 4 along the groove 3 of the inclined slide 2, causing the sliding plate 8 to move it. The spring 22 of the buffer mechanism is compressed by the first connecting rod 24 and the second connecting rod 25, absorbing the recoil impact. After the recoil dissipates, the spring 22 elastically returns to its original position, pushing the slider 4 and sliding plate 8 back to their initial positions. The limiting plate 5 is threadedly connected to the threaded hole 6 via screws 7, limiting the sliding stroke of the slider 4 and preventing it from sliding out of the groove 3. The inclined slide 2 features an inclined design to match the flight angle of the racing drone; the weight reduction groove 21 reduces the overall weight; and the mounting plate 1 has pre-drilled mounting holes, making it compatible with most racing drones on the market.

[0025] Example 2 Please see Figures 1-6 The present invention provides a reciprocating type multi-functional pneumatic jet for unmanned aerial vehicles, comprising: a mounting plate 1, an inclined slide 2 fixedly connected to the mounting plate 1, a slide groove 3 provided inside the inclined slide 2, a slider 4 slidably connected inside the slide groove 3, a buffer mechanism for assisting the slider 4 to reset installed inside the slide groove 3, and a limiting mechanism for limiting the slider 4 installed outside the inclined slide 2; a sliding plate 8 fixedly connected to the slider 4, an mounting tube 9 fixedly connected to the sliding plate 8, a gas cylinder 10 fixedly connected inside the mounting tube 9, an air inlet 23 connected to the input end of the gas cylinder 10, a sliding air valve 17 connected to the output end of the gas cylinder 10, a release mechanism for pushing the sliding air valve 17 to open and close installed outside the mounting tube 9, and a 2-point threaded connector 20 installed at the output end of the sliding air valve 17.

[0026] Furthermore, the buffer mechanism includes a second insertion rod 25, which is fixedly connected to the inside of the slide groove 3. A spring 22 is sleeved on the outside of the second insertion rod 25. A first insertion rod 24 is fixedly connected to the outside of the slider 4 and is inserted into the inside of the spring 22.

[0027] Furthermore, the limiting mechanism includes two threaded holes 6, both of which are located on the outside of the inclined slide 2. A limiting plate 5 is provided on the outside of the inclined slide 2. Two screws 7 are threadedly connected to the outside of the limiting plate 5, and the two screws 7 are threadedly connected to the inside of the two threaded holes 6 respectively.

[0028] Furthermore, the release mechanism includes a fixing block 12, which is fixedly connected to the outside of the mounting tube 9. A servo motor 13 is mounted on the outside of the fixing block 12. The output shaft of the servo motor 13 is fixedly connected to a rotating wheel 14. A first hinge post 15 is fixedly connected to the outside of the rotating wheel 14 at a non-center position. A hinge rod 16 is hinged to the outside of the first hinge post 15. A clamp 18 is fixedly connected to the outside of the sliding air valve 17. A second hinge post 19 is fixedly connected to the outside of the clamp 18. One end of the hinge rod 16 is hinged to the second hinge post 19.

[0029] Furthermore, a pressure gauge 11 is installed on the outside of the gas cylinder 10.

[0030] Furthermore, the tilting slide 2 has multiple weight-reducing grooves 21 on its exterior.

[0031] Furthermore, the bottom of the sliding plate 8 is slidably connected to the inclined slide 2.

[0032] In use, this invention first fills the gas cylinder 10 with compressed gas through the filling nozzle 23, and the pressure inside the cylinder is monitored in real time by the pressure gauge 11. When the spray is triggered, the servo motor 13 of the release mechanism drives the rotating wheel 14 to rotate. The first hinge column 15 on the rotating wheel 14 drives the hinge rod 16 to push and pull the second hinge column 19, and opens the sliding gas valve 17 through the clamp 18. The compressed gas in the gas cylinder 10 is then released instantly through the external nozzle connected to the 2-point threaded connector 20 to complete operations such as breaking windows, netting, and spraying tear gas powder. The recoil generated by the spray will cause the sliding plate 8 to... The slider 4 slides along the groove 3 of the inclined slide 2. The spring 22 of the buffer mechanism is compressed to absorb the impact under the cooperation of the first plug rod 24 and the second plug rod 25. Then, the elastic reset drives the slider 4 and the sliding plate 8 back to the initial position. The limiting plate 5 on the inclined slide 2 is fixed by the screw 7 and the threaded hole 6, which can limit the sliding stroke of the slider 4 to prevent derailment. The inclined slide 2 adopts an inclined design to fit the flight tilt angle of the racing machine. The weight reduction groove 21 reduces the overall weight. The mounting plate 1 has a reserved installation structure, which can be compatible with most racing machines on the market.
