Description

Technical Field

[0001] This invention belongs to the field of robotics, and in particular relates to a method for operating a dart launcher. Background Technology

[0002] Darts, as a type of miniature throwing device, are increasingly popular as a form of entertainment. With the development of automated equipment, users can now use small launchers to launch darts, replacing manual throwing. These launchers can launch darts to hit armor plates, only half the size of an A4 sheet of paper, at distances of 16 to 20 meters, achieving long-range, high-damage attacks on buildings. Small launchers can also launch objects such as badminton shuttlecocks, tennis balls, and ping-pong balls.

[0003] A Chinese patent application with patent number 202120501413.3 and publication date of December 3, 2021, describes a dart-launching robot. The robot includes a frame with a launcher mounted on it. The launcher includes a launcher stand, and a launch seat is mounted on the launcher stand via a slide rail. An elastic element connects the launch seat and the launcher stand. A motion component is mounted on the launcher stand to drive the launch seat along the slide rail. A feeding component is located directly above the launcher stand, including a feeding plate with a cylinder mounted on it. The cylinder and the slide rail have overlapping projections on the same horizontal plane. However, this invention uses a cylinder to push the dart into the launch seat during the feeding process. The height difference between the launch seat and the feeding plate makes it easy for the dart to fall off during feeding. Furthermore, the alignment accuracy between the dart and the launch seat is low. Each feeding requires a third motor to lift the movable frame as close as possible to the feeding plate before pushing the dart from the plate into the launch seat, followed by readjustment of the launching direction. This direction adjustment process is slow and results in low launching efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a method for operating a dart launcher that can quickly launch aircraft and launch from multiple directions and angles, and is simple to operate.

[0005] To achieve the above objectives, a method for operating a dart launcher is provided. The dart launcher utilizes a small aircraft launcher, which includes a base rotation adjustment module, a feeding and launching module, and a height adjustment module. The feeding and launching module is located above the height adjustment module and is fixed to the base rotation adjustment module. The feeding and launching module contains a launching channel. The feeding and launching module includes a feeding and launching frame, a launching mechanism, a feeding mechanism, and a directional stabilizing mechanism. The launching mechanism, feeding mechanism, and directional stabilizing mechanism are all fixed to the launching frame. The feeding mechanism is movably connected to the rear end of the feeding and launching frame and is used to store the dart and to bring the dart to be launched into contact with the launching mechanism for launch. The launching mechanism is fixed to the front end of the feeding and launching mechanism, and the directional stabilizing mechanism is located in the middle of the launching frame. Figure 2 and Figure 5 As shown, the feeding mechanism includes a feeding motor, a feeding screw coupling, a feeding head fixing component, a feeding tail fixing component, an upper hinge plate, a feeding lower hinge plate, a feeding push plate, a loading screw, and a feeding screw nut. The feeding head fixing component is fixed to the upper end of the feeding transmitter frame. The output shaft of the feeding motor is fixedly connected to one end of the feeding screw coupling, and the other end of the feeding screw coupling is fixedly connected to the loading screw. The other end of the loading screw passes through the feeding head fixing component and connects to the feeding tail fixing component. The feeding head fixing component and the feeding tail fixing component... Each component is equipped with a bearing, and the loading screw rotates within the bearing. The middle of the loading screw also passes through a feeding push plate, which contains a feeding screw nut. The loading screw and the feeding screw nut are movably connected. An upper hinge plate is fixedly connected to the feeding push plate, and a lower hinge plate is movably connected to the other end of the upper hinge plate. A lower feeding plate is fixed to the front of the lower hinge plate, and the lower feeding plate is aligned with the launching channel. The end of the launching channel closest to the launching mechanism is the launching port, and the portion of the launching channel that extends into the feeding mechanism is the feeding port. The specific steps are as follows:

[0006] (1) When preparing for launch, the spacecraft is stored at the rear end of the launch channel within the fuel supply and launch module;

[0007] (2) Adjust the launch direction using the base rotation adjustment module;

[0008] (3) The height adjustment module adjusts the launch height;

[0009] (4) The feeding mechanism pushes the aircraft so that the aircraft to be launched comes into contact with the launch mechanism;

[0010] (5) The launch mechanism accelerates the launch of the aircraft;

[0011] Step (4) also includes:

[0012] (4.1) The output end of the feeding motor rotates, driving the feeding screw coupling to rotate;

[0013] (4.2) The feeding screw coupling drives the filling screw to rotate;

[0014] (4.3) The rotation of the filling screw drives the feeding screw nut to move along the axial direction of the filling screw, and at the same time drives the feeding push rod to move along the axial direction of the filling screw;

[0015] (4.4) The feeding pusher plate drives the lower feeding plate to move the aircraft along the launch channel toward the launch mechanism, pushing the aircraft into the launch mechanism.

[0016] With the above setup, multiple aircraft are stored at intervals at the rear end of the launch channel within the feeding and launching module during launch preparation. The feeding mechanism within the module stores the aircraft and facilitates contact between the aircraft to be launched and the launch mechanism. A directional stabilizing mechanism is located in the middle of the launch mechanism to adjust the feeding and launching directions of the aircraft. Therefore, multiple aircraft can be stored in the feeding mechanism awaiting launch, resulting in high overall feeding accuracy. The next aircraft can be immediately pushed to the launch mechanism for launch after the previous one is launched, ensuring fast feeding speed and high launch efficiency. The output of the feeding motor rotates, driving the feeding screw coupling, which in turn drives the loading screw. The system provides inertia for shock absorption and elimination of radial forces. The loading screw and the feeding screw nut in the feeding push plate form a screw-nut transmission. The rotation of the loading screw drives the feeding screw nut to move along the loading screw axis, thereby driving the feeding push plate to move along the loading screw axis. When the aircraft is being fed, the feeding motor drives the loading screw to rotate. The rotation of the loading screw drives the feeding push plate to move towards the launch mechanism. The feeding push plate drives the lower feeding plate to push the aircraft along the launch channel towards the launch mechanism. The feeding process has high docking accuracy. The launch direction can be adjusted through the base rotation adjustment module, and the launch height can be adjusted through the altitude adjustment module, thereby enabling the launch of aircraft in multiple directions and at multiple altitudes. The operation is simple.

[0017] Furthermore, a loading optical shaft is also provided on one side of the loading screw. One end of the loading optical shaft passes through the feeding head fixing member, the other end passes through the feeding tail fixing member, and the middle part passes through the feeding push plate. The loading optical shaft is connected to both the feeding head fixing member and the feeding tail fixing member by a fixing ring. The loading optical shaft is movably connected to the feeding push plate by a bearing. Step (4.3) also includes (4.31) the loading screw drives the feeding push rod to move along the loading screw axis. At the same time, the feeding push rod slides along the loading optical shaft located on one side of the loading screw.

[0018] The above configuration includes a loading optical shaft located on one side of the loading screw to increase the stability of the movement of the feeding push plate. One end of the loading optical shaft passes through the feeding head fixing component, the other end passes through the feeding tail fixing component, and the middle part passes through the feeding push plate. The loading optical shaft is connected to both the feeding head fixing component and the feeding tail fixing component through a fixing ring. The loading optical shaft is connected to the feeding push plate through a bearing. By setting a loading optical shaft on one side of the loading screw, the loading screw drives the feeding push plate to move for guidance, thereby improving the stability of the feeding process.

[0019] Furthermore, the launching mechanism includes two pairs of friction wheels and corresponding acceleration motors. The friction wheels are located on both sides of the launching channel. The acceleration motors are fixed inside the launching frame via acceleration motor mounting brackets. The friction wheels are fixedly connected to the output shaft of the acceleration motors. The upper and lower mounting plates are respectively connected to the upper and lower ends of the side mounting plates. The acceleration motor mounting bracket includes an upper mounting plate, a lower mounting plate, and a side mounting plate. The side mounting plate is set perpendicular to the length direction of the launching frame. The side mounting plate has snap-fit ​​interfaces on both sides. The upper and lower mounting plates have snap-fit ​​protrusions at both ends along the length direction of the launching frame that match the snap-fit ​​interfaces. The upper mounting plate and the side mounting plate are detachably connected to the snap-fit ​​interfaces via the snap-fit ​​protrusions. The lower mounting plate and the side mounting plate are detachably connected to the snap-fit ​​interfaces via the snap-fit ​​protrusions. The side mounting plate has a support groove in the middle. Step (5) specifically includes:

[0020] (5.1) The motor accelerates the rotation, which in turn drives the friction wheel to rotate faster;

[0021] (5.2) The feeding pusher pushes the spacecraft to be launched into the launch mechanism;

[0022] (5.3) The two sides of the aircraft rub against the friction wheels, and the aircraft is accelerated and launched under the action of the friction wheels.

[0023] In the above configuration, the friction wheels are driven by independent acceleration motors, which are fixed on both sides of the launch channel inside the launcher frame. The friction wheels are fixedly connected to the output shaft of the acceleration motors. After the friction wheels are accelerated to a specified speed by the acceleration motors, the feeding pusher pushes the aircraft to be launched into the launch mechanism. The two sides of the aircraft rub against the friction wheels, and the aircraft is accelerated and launched under the action of the friction wheels. The two opposing friction wheels realize the acceleration of the aircraft. The upper and lower fixed plates are fixedly connected to the side fixed plates through snap-fit ​​protrusions and snap-fit ​​interfaces, respectively, which makes it easy to add or remove the required acceleration motors and friction wheels, thereby adjusting the launch speed of the aircraft leaving the launch port.

[0024] Furthermore, the base rotation adjustment module includes a base, a frustum turntable, a rotation adjustment motor, a motor fixing plate, a drive gear, and a rack plate. The frustum turntable is rotatably connected to the base. The rotation adjustment motor and the frustum turntable are fixedly connected through the motor fixing plate. The lower end of one side of the motor fixing plate is fixedly connected to the upper end of the frustum turntable. The rotation adjustment motor is fixed to the upper surface of the motor fixing plate. The output shaft of the rotation adjustment motor passes through the motor fixing plate and is fixedly connected to the drive gear. The rack plate is fixed to the lower end of the base. The drive gear meshes with the rack plate. The rotation adjustment motor drives the drive gear to rotate and meshes with the rack plate. Since the rack plate is fixed to the base, the rotation adjustment motor drives the drive gear to rotate and meshes with the rack plate. Since the rack plate is fixed to the base, the rotation adjustment motor is fixed to the motor fixing plate. Thus, the drive gear meshes with the rack plate, causing the frustum turntable to rotate on the base. Step (2) specifically includes:

[0025] (2.1) The rotation of the output end of the rotary regulating motor drives the drive gear to rotate;

[0026] (2.2) The driving gear moves along the arc of the rack plate;

[0027] (2.3) The rotary adjustment motor drives the support frame and the truncated disc, which are fixedly connected to the rotary adjustment motor, to rotate on the base along the circumference of the truncated disc.

[0028] The above configuration involves the output of the rotary adjustment motor rotating to drive the drive gear. The drive gear meshes with the rack plate, so the drive gear moves along the arc of the rack plate. The movement of the drive gear drives the rotary adjustment motor to move, which in turn drives the support frame and the frustum turntable, which are fixedly connected to the rotary adjustment motor, to rotate on the base along the circumference of the frustum turntable. The rotary structure is simple and reliable.

[0029] Furthermore, the height adjustment module includes a height adjustment motor, a height adjustment lead screw, a height adjustment lead screw coupling, a lead screw seat, an adjustment lead screw nut, a lead screw nut seat, a linear guide, a linear guide slider, a linkage fixing plate, support rods, and a support frame. The lower end of the support frame is fixedly connected to the upper end of the frustum turntable. The linkage fixing plate is slidably disposed at the front end of the support frame. Support rods are provided on both sides of the upper end of the linkage fixing plate. The lower ends of the support rods are rotatably connected to the linkage fixing plate, and the upper ends of the support rods are rotatably connected to the lower front end of the transmitter frame. The rear part of the support frame is rotatably connected to the lower rear end of the transmitter frame. The height adjustment motor is located in the middle of the support frame. The height adjustment motor is fixedly connected to the middle of the upper end of the height motor fixing plate. The two sides of the upper end of the height motor fixing plate are fixedly connected to the lower ends of both sides of the support frame. The output end of the height adjustment motor is connected to one end of the height adjustment lead screw coupling. The other end of the height adjusting screw coupling is connected to the height adjusting screw, and the other end of the height adjusting screw is movably connected to the bearing in the screw seat. The screw seat is fixed on the support frame. The middle part of the height adjusting screw passes through the screw nut seat at the lower end of the linkage fixing plate. The screw nut seat is provided with an adjusting screw nut. The height adjusting screw is movably connected to the adjusting screw nut. Linear rails are provided on both sides of the support frame. Linear rail sliders are provided on both sides of the lower end of the linkage fixing plate. The lower end of the linear rail slider is provided with a sliding groove corresponding to the linear rail. The output end of the height adjusting motor is in the same direction as the length direction of the linear rail. Pulley fixing plates are also provided on both the front and rear ends of the support frame. Pulley fixing plates are provided with pulleys. The base is provided with an arc guide rail corresponding to the pulley. A shock-absorbing plate is provided between the arc guide rail and the pulley fixing plate as a support. Step (3) specifically includes:

[0030] (3.1) The height adjustment motor drive output end rotates, which in turn drives the height adjustment screw coupling to rotate;

[0031] (3.2) The height adjusting screw coupling drives the height adjusting screw to rotate;

[0032] (3.3) The rotation of the height adjustment screw drives the linkage fixing plate on the screw nut seat to move along the length of the linear guide;

[0033] (3.4) When the linkage fixing plate moves, it will drive the support rod on the linkage fixing plate to move;

[0034] (3.5) When the support rod moves, it will drive the front part of the transmitter frame to move, and the height of the front part of the transmitter frame will change, thereby completing the adjustment of the launch height.

[0035] With the above setup, when adjusting the launch altitude, the height adjustment motor drive output rotates, causing the height adjustment lead screw coupling to rotate. The lead screw coupling then drives the height adjustment lead screw to rotate, forming a lead screw-nut transmission with the lead screw nut. The lead screw nut moves axially along the height adjustment lead screw nut, thus causing the linkage fixing plate on the lead screw nut seat to move along the length of the linear guide. When the linkage fixing plate moves, it causes the support rod on the linkage fixing plate to move. When the support rod moves, it causes the front of the launch frame to move. Since the rear of the launch frame is connected to the rear of the support frame by a pin, the height of the front of the launch frame changes when the rear of the launch frame is movably connected, thereby adjusting the launch altitude. The height adjustment method is simple and reliable. During rotation, the bullseye wheels located at the front and rear ends of the support frame slide along the arc guide rail on the base. The bullseye wheels at the front and rear ends of the support frame can provide sufficient support force for the support frame. The shock-absorbing plate can provide a preload force when the pulleys rotate and when the aircraft is launched, which is used to counteract the recoil force during launch and the pressure during rotation.

[0036] Furthermore, the directional stabilization mechanism includes side limiting plates, side limiting brackets, an upper guide rail, and a lower guide rail. The side limiting plates are vertically spaced and fixed on both sides of the launch channel, extending from the feed inlet of the launch channel to the middle of the launch channel. The side limiting plates are fixed together by limiting fixing plates. The limiting fixing plates are L-shaped plates, with four or more limiting protrusions at one end. The limiting protrusions engage with the limiting grooves on the side limiting plates. The side limiting plates near the feed inlet have an end that tilts outwards. The device is angled, with the side limiting brackets fixed to both sides of the launch channel, connected to the side limiting plates, and extending to one end of the launch mechanism. The upper guide rail is fixed to the upper side of the launch channel, with one side of the upper guide rail fixed to the lower end of the feeding tail fixing component and the other side of the upper guide rail fixed to one end of the launch port. The lower guide rail is fixed to the lower side of the launch channel, with one end of the lower guide rail fixed to one end of the feeding port and the other end of the lower guide rail fixed to one end of the launch port. The side limiting plates, side limiting brackets, upper guide rails, and lower guide rails are in contact with the fuselage of the aircraft.

[0037] The above configuration, with the side limiting plate, side limiting bracket, upper guide rail, and lower guide rail fitting snugly against the aircraft's fuselage, ensures stable launch direction. The smooth surfaces of the side limiting plate, side limiting bracket, upper guide rail, and lower guide rail reduce friction. The side limiting plate, with its end angled outwards near the feed inlet, creates a larger opening in the feed inlet direction, facilitating feeding. After feeding, the material is guided by the lower guide rail. The upper guide rail, located near the launch port, and the upper and lower guide rails, limit the aircraft's entry into the launch port from the vertical direction of the launch channel, allowing the aircraft to enter the launch port more effectively and reliably.

[0038] Furthermore, the feeding launcher frame is provided with two or more micro switches spaced apart on one side, and the feeding pusher plate is provided with a micro switch trigger on the side near the micro switch. The interval length of the micro switches is the same as the length of the aircraft. Each time the feeding pusher plate pushes an aircraft forward, the micro switch trigger touches a micro switch. Between steps (4) and (5), there is also step (6). Each time the feeding pusher plate pushes an aircraft into the launch mechanism, the micro switch trigger on the side of the feeding pusher plate near the micro switch contacts the micro switch. The micro switch is connected to send a start signal to the acceleration motor of the launch mechanism. The acceleration motor starts to accelerate the friction wheel.

[0039] With the above setup, when the feeding pusher pushes the aircraft to feed the launch mechanism, each time an aircraft is pushed into the launch mechanism, the micro switch trigger on the side of the feeding pusher near the micro switch contacts the micro switch. The micro switch connects to send a start signal to the acceleration motor of the launch mechanism, and the acceleration motor starts to accelerate the friction wheel, thereby launching the aircraft to be launched. The trigger switch realizes automatic acceleration launch.

[0040] Furthermore, the feeding transmitter frame is also equipped with an infrared aiming device, which is located at the upper end of the emission port and emits infrared laser light to illuminate the emission port direction.

[0041] The above settings allow you to adjust the firing direction of the launch port and use the infrared laser emitted by the infrared sight to determine the firing direction. This makes it easy to observe whether the launch point is aligned with the target location and achieve long-range target hits. Attached Figure Description

[0057] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0058] like Figure 1-14 As shown, a small aircraft launcher is used to launch a small aircraft 1. The small aircraft launcher includes a base rotation adjustment module 2, a feeding and launching module 3, and an altitude adjustment module 4. The feeding and launching module 3 is located above the altitude adjustment module 4, and the altitude adjustment module 4 is fixed to the base rotation adjustment module 2. The feeding and launching module 3 has a launching channel 5 inside. The feeding and launching module 3 includes a feeding and launching frame 31, a launching mechanism 32, a feeding mechanism 33, and a directional stabilizing mechanism 34. The launching mechanism 32, the feeding mechanism 33, and the directional stabilizing mechanism 34 are all fixed to the launching frame 31. The feeding mechanism 33 is movably connected to the rear end of the feeding and launching frame 31 and is used to store the aircraft 1 and to bring the aircraft 1 to be launched into contact with the launching mechanism 32 for launch. The launching mechanism 32 is fixed to the front end of the feeding and launching mechanism 31, and the directional stabilizing mechanism 34 is located in the middle of the launching frame 32. Figure 2 and Figure 5As shown, the feeding mechanism 33 includes a feeding motor 331, a feeding screw coupling 332, a feeding head fixing member 333, a feeding tail fixing member 334, an upper hinge plate 335, a feeding lower hinge plate 336, a feeding push plate 337, a loading screw 338, and a feeding screw nut 339. The feeding head fixing member 333 is fixed to the upper end of the feeding transmitter frame 31. The output shaft of the feeding motor 331 is fixedly connected to one end of the feeding screw coupling 332, and the other end of the feeding screw coupling 332 is fixedly connected to the loading screw 338. The other end of the loading screw 338 passes through the feeding head fixing member 333 and is connected to the feeding head fixing member 334. The tail fixing member 334 is connected, and the feeding head fixing member 333 and the feeding tail fixing member 334 are both equipped with bearings. The loading screw 338 rotates in the bearing. The middle part of the loading screw 338 also passes through the feeding push plate 337. The feeding push plate 337 is equipped with a feeding screw nut 339. The loading screw 338 and the feeding screw nut 339 are movably connected. The feeding push plate 337 is fixedly connected to an upper hinge plate 335. The other end of the upper hinge plate 335 is movably connected to a lower hinge plate 336. The front side of the lower hinge plate 336 is fixed with a lower feeding plate 330. The lower feeding plate 330 extends into the launching channel 5.

[0059] With the above setup, multiple aircraft 1 are stored at intervals at the rear end of the launch channel 5 within the feeding and launching module 3 during launch preparation. The feeding mechanism 33 within the feeding and launching module 3 is used to store the aircraft 1 and to bring the aircraft 1 to be launched into contact with the launching mechanism 32 for launch. The directional stabilizing mechanism 34 is located in the middle of the launching mechanism 32 to adjust the feeding direction and launch direction of the aircraft 1. Therefore, multiple aircraft 1 can be stored in the feeding mechanism 33 and wait for the launching mechanism 32 to launch them. The overall feeding accuracy is high. After the previous aircraft 1 is launched, the next aircraft 1 can be immediately pushed to the launching mechanism 32 for launch. The feeding speed is fast and the launch efficiency is high. The output end of the feeding motor 331 rotates, driving the feeding screw coupling 332 to rotate, which in turn drives the loading screw 338 to rotate. The inertia provides shock absorption and eliminates radial force. The loading screw 338 and the feeding screw nut 339 in the feeding push plate 337 form a screw-nut transmission. The rotation of the loading screw 338 drives the feeding screw nut 339 to move axially along the loading screw 338, thereby driving the feeding push plate 337 to move axially along the loading screw 338. When the aircraft 1 is feeding, the feeding motor 331 drives the loading screw 338 to rotate. The rotation of the loading screw 338 drives the feeding push plate 337 to move towards the launch mechanism 32. The feeding push plate 337 drives the lower feeding plate 330 to push the aircraft 1 along the launch channel 5 towards the launch mechanism 32. The launch direction can be adjusted by the base rotation adjustment module, and the launch height can be adjusted by the height adjustment module 4, thereby realizing the launch of the aircraft 1 in multiple directions and at multiple heights. The operation is simple.

[0060] like Figure 2 and Figure 3 As shown, a loading optical shaft 351 is also provided on one side of the loading screw 338. One end of the loading optical shaft 351 passes through the feeding head fixing member 333, the other end passes through the feeding tail fixing member 334, and the middle part passes through the feeding push plate 337. The loading optical shaft 351 is movably connected to the feeding head fixing member 333 and the feeding tail fixing member 334 through a fixing ring 352. The loading optical shaft 351 is connected to the feeding push plate 337 through a bearing.

[0061] The above configuration includes a loading optical shaft 351 located on one side of the loading screw 338 to increase the stability of the movement of the feeding push plate. One end of the loading optical shaft 351 on one side of the loading screw 338 passes through the feeding head fixing member 333, the other end passes through the feeding tail fixing member 334, and the middle part passes through the feeding push plate 337. The loading optical shaft 351 is movably connected to the feeding head fixing member 333 and the feeding tail fixing member 334 through a fixing ring 352. By setting the loading optical shaft 351 on one side of the loading screw 337, the loading screw 337 drives the feeding push plate 337 to move for guidance. The loading optical shaft 351 and the feeding push plate 337 are connected by a bearing to improve the stability of the feeding.

[0062] like Figure 2 , Figure 11 and Figure 12 As shown, in this embodiment, the launching mechanism 32 includes two pairs of friction wheels 321 and corresponding acceleration motors 322. The friction wheels 321 are located on both sides of the launching channel 5. The acceleration motors 322 are fixed inside the launching frame 31 by acceleration motor mounting brackets 323. The friction wheels 321 are fixedly connected to the output shaft of the acceleration motors 322. The acceleration motor mounting brackets 323 include an upper mounting plate 324, a lower mounting plate 325, and a side mounting plate 326. The upper mounting plate 324 and the lower mounting plate 325 are respectively connected to the upper and lower ends of the side mounting plate 326. In this embodiment, there are two side mounting plates 326, which are located on both sides of the upper mounting plate 324 and the lower mounting plate 325 and connected to the upper mounting plate 326. The upper fixing plate 324 and the lower fixing plate 325 are connected to form a fixing frame. An acceleration motor 322 is fixedly connected to the upper fixing plate 324. The side fixing plate 326 is perpendicular to the length direction of the transmitter frame 31. The side fixing plate 326 has a snap-fit ​​interface 3261 on both sides. The upper fixing plate 324 and the lower fixing plate 325 have snap-fit ​​protrusions 3262 at both ends along the length direction of the transmitter frame 31 that match the snap-fit ​​interface 3261. The upper fixing plate 324 and the side fixing plate 3262 are fixedly connected to the snap-fit ​​interface 3261 through the snap-fit ​​protrusion 3262. The lower fixing plate 325 and the side fixing plate 326 are detachably connected to the snap-fit ​​interface 3261 through the snap-fit ​​protrusion 3262. The side fixing plate 326 has a support groove 3263 in the middle.

[0063] In the above configuration, two opposing friction wheels 321 accelerate the aircraft 1. Each friction wheel 321 is driven by an independent acceleration motor 322, which is fixed on both sides of the launch channel 5 inside the launch frame 31. The friction wheels 321 are fixedly connected to the output shaft of the acceleration motor 322. After the friction wheels 321 are accelerated to a specified speed by the acceleration motor 322, the feeding push plate 337 pushes the aircraft 1 to be launched into the launch mechanism 32. The two sides of the aircraft 1 rub against the friction wheels 321, and the aircraft 1 is accelerated and launched under the action of the friction wheels 321. The two opposing friction wheels 321 accelerate the aircraft 1. The upper fixing plate 324 and the lower fixing plate 325 are detachably connected to the side fixing plate 3262 through the snap-fit ​​protrusion 3262 and the snap-fit ​​interface 3261, respectively, which makes it easy to add or remove the required acceleration motor 322 and friction wheels 321, thereby adjusting the launch speed of the aircraft 1 from the launch port.

[0064] like Figure 4 and Figure 5 As shown, the base rotation adjustment module 2 includes a base 21, a frustum turntable 22, a rotation adjustment motor 23, a motor fixing plate 28, a drive gear 25, and a rack plate 26. The frustum turntable 22 is rotatably connected to the base 21, and the rotation adjustment motor 23 and the frustum turntable 22 are connected by the motor fixing plate 28. The motor mounting plate 28 is fixedly connected to the upper end of the frustum turntable 22. The rotary adjustment motor 23 is fixed to the upper surface of the motor mounting plate 28. The output shaft of the rotary adjustment motor 23 passes through the motor mounting plate 28 and is fixedly connected to the drive gear 25. The rack plate 26 is fixed to the lower end of the base 21. The output shaft of the rotary adjustment motor 23 is fixedly connected to the drive gear 25. The drive gear 25 meshes with the rack plate 26. The lower end of one side of the motor mounting plate 28 is fixedly connected to the frustum turntable 22. The rotary adjustment motor 23 drives the drive gear 25 to rotate and mesh with the rack plate 26. Since the rack plate 26 is fixed to the base 21, the rotary adjustment motor 23 drives the drive gear 25 to rotate and mesh with the rack plate 26. Since the rack plate 26 is fixed to the base 21, the rotary adjustment motor 23 is fixed to the motor mounting plate 28. Thus, the meshing of the drive gear 25 and the rack plate 26 drives the frustum turntable 22 to rotate on the base 21.

[0065] In the above configuration, the output of the rotary adjustment motor 23 rotates, driving the drive gear 25 to rotate. The drive gear 25 meshes with the rack plate 25. Therefore, the drive gear 25 moves along the arc of the rack plate 25. At the same time, the movement of the drive gear 25 drives the rotary adjustment motor 23 to move. Simultaneously, the rotary adjustment motor 23 drives the motor fixing plate 28, which is fixedly connected to the rotary adjustment motor 23, to rotate. At the same time, the frustum turntable 22, which is fixedly connected to the motor fixing plate 28, rotates on the base 21 along the circumference of the frustum turntable 22. The rotating structure is simple and reliable.

[0066] like Figure 13 As shown, two parallel protruding pillars 32631 are also provided in the middle of the support groove 3263. The two protruding pillars 32631 form a first groove 32632, and a second groove 32633 is formed on both sides of the first groove 32632. With the above arrangement, when the aircraft 1 enters the launch port, the bottom of the aircraft 1 contacts the two protruding pillars 32631 to support the aircraft. The flight fins on both sides of the aircraft are accommodated by the second groove 32622 to achieve a guiding function, so that the aircraft can smoothly enter the launch port.

[0067] like Figure 6 and Figure 7As shown, the height adjustment module 4 includes a height adjustment motor 41, a height adjustment lead screw 42, a height adjustment lead screw coupling 43, a lead screw seat 44, an adjustment lead screw nut 45, a lead screw nut seat 46, a linear guide 47, a linear guide slider 48, a linkage fixing plate 49, support rods 40, and a support frame 27. The lower end of the support frame 27 is fixedly connected to the upper end of the frustum turntable 22. The linkage fixing plate 49 is slidably disposed at the front end of the support frame 27. Support rods 40 are provided on both sides of the upper end of the linkage fixing plate 49. The lower end of the support rod 40 is rotatably connected to the linkage fixing plate 49. The upper end of the support rod 40 is rotatably connected to the lower front end of the transmitter frame 31. The rear end of the support frame 27 is rotatably connected to the lower rear end of the transmitter frame 31. The height adjustment motor 41 is located in the middle of the support frame 27. The height adjustment motor 41 is fixedly connected to the middle upper end of the height motor fixing plate 410. The upper sides of the height motor fixing plate 410 are fixedly connected to the lower ends of both sides of the support frame 40. The output end of the height adjustment motor 41 is connected to one end of the height adjustment screw coupling 43. The other end of the height adjusting screw coupling 43 is connected to the height adjusting screw 42. The other end of the height adjusting screw 42 is movably connected to a bearing inside the screw seat 44. The screw seat 44 is fixed on the support frame 27. The middle part of the height adjusting screw 42 passes through the screw nut seat 46 at the lower end of the linkage fixing plate 49. The screw nut seat 46 is provided with an adjusting screw nut 45. The height adjusting screw 42 is movably connected to the adjusting screw nut 45. Linear rails 47 are provided on both sides of the support frame 27. The linkage fixing plate 49... The lower end of the support frame 27 is provided with linear guide sliders 48 on both sides. The lower end of the linear guide sliders 48 is provided with a slide groove 480 corresponding to the linear guide 47. The output end of the height adjustment motor 41 is in the same direction as the length direction of the linear guide 47. The front and rear ends of the support frame 27 are also provided with pulley fixing plates 240. The pulley fixing plates 240 are provided with pulleys 24. The base 21 is provided with arc guide rails 29 corresponding to the pulleys 24. A shock-absorbing plate 290 is provided between the arc guide rails 29 and the pulley fixing plates 240 as a support.

[0068] With the above settings, when adjusting the launch height, the height adjustment motor 41 drives the output end to rotate, which in turn drives the height adjustment screw coupling 43 to rotate. The height adjustment screw coupling 43 drives the height adjustment screw 42 to rotate. The height adjustment screw 42 and the adjustment screw nut 45 form a screw-nut transmission. The adjustment screw nut 45 moves axially along the height adjustment screw 42 nut, thus driving the linkage fixing plate 49 on the screw nut seat 46 to move along the length direction of the linear guide 47. When the linkage fixing plate 49 moves, it drives the support rod 40 on the linkage fixing plate 49 to move. The movement of the support rod 40 drives the front part of the transmitter frame 31 to move. Because the rear of the launcher frame 31 is movably connected to the rear of the support frame 27, the height of the front of the launcher frame 31 can be changed when the rear of the launcher frame 31 is movably connected, thereby adjusting the launch height. The height adjustment method is simple and reliable. When rotating, the bullseye wheels 24 located at the front and rear ends of the support frame 27 slide along the arc guide rail on the base 21. The bullseye wheels 24 at the front and rear ends of the support frame 27 can provide sufficient support force for the support frame 27. The shock-absorbing plate 290 can provide a preload force when the pulley 24 rotates and when the aircraft 1 is launched, which is used to counteract the recoil force during launch and the pressure during rotation.

[0069] like Figure 10 As shown, the directional stabilizing mechanism 34 includes side limiting plates 341, side limiting brackets 342, upper guide rails 343, and lower guide rails 344. The side limiting plates 341 are vertically spaced and fixed on both sides of the launch channel 5, extending from the feed inlet of the launch channel 5 to the middle of the launch channel 5. The side limiting plates 341 are fixed together by limiting fixing plates 327. The limiting fixing plates 327 are L-shaped plates, and one end of the limiting fixing plates 327 is provided with four or more limiting protrusions. The limiting protrusions are engaged and fixed with the limiting grooves on the side limiting plates 341. The side limiting plates 341 are inclined outward on the side near the feed inlet. The side limiting brackets are fixed on both sides of the launch channel 5 and the side limiting plates 342. Position plate 342 is connected to and extends to one end of the launching mechanism. The upper guide rail 343 is fixed to the upper side of the launching channel 5. One side of the upper guide rail 343 is fixed to the lower end of the feeding tail fixing component, and the other side of the upper guide rail 343 is fixed to one end of the launching port. There is one upper guide rail 343 and two lower guide rails 344. One side of the upper guide rail 343 is located between the two lower guide rails 344. The lower guide rail 344 is fixed to the lower side of the launching channel 5. One end of the lower guide rail 344 is fixed to one end of the feeding port, and the other end of the lower guide rail 344 is fixed to one end of the launching port. The side limiting plate 341, the side limiting bracket 342, the upper guide rail 343 and the lower guide rail 344 are attached to the fuselage of the aircraft 1.

[0070] The above configuration, with the side limiting plate 341, side limiting bracket 342, upper guide rail 343, and lower guide rail 344 fitting snugly against the fuselage of the aircraft 1, can stabilize the launch direction; the smooth surfaces of the side limiting plate 341, side limiting bracket 342, upper guide rail 343, and lower guide rail 344 reduce friction; the side limiting plate 341 is tilted outwards near the feed port, which makes the feed port opening larger, thus facilitating feeding; and after feeding, it is guided by the lower guide rail. The upper guide rail is set at the end near the launch port, and the upper guide rail 343 and lower guide rail 344 limit the aircraft 1 from the vertical direction of the launch channel 5 to enter the launch port, so that the aircraft can enter the launch port better and more reliably.

[0071] like Figure 2 As shown, the feeding launcher frame 31 has two or more microswitches 311 spaced apart on one side, and the feeding pusher plate 337 has a microswitch trigger 312 on the side near the microswitch 311. The spacing length of the microswitches 311 is the same as the length of the aircraft 1. Each time the feeding pusher plate 337 pushes an aircraft 1 forward, the microswitch trigger 312 touches a microswitch 311.

[0072] With the above configuration, when the feeding pusher plate 337 pushes the aircraft 1 to feed the launch mechanism 32, each time an aircraft 1 is pushed into the launch mechanism 32, the micro switch 312 on the side of the feeding pusher plate 337 near the micro switch 311 contacts the micro switch 311. The micro switch 311 is connected to send a start signal to the acceleration motor 322 of the launch mechanism 32. The acceleration motor 322 starts to accelerate the friction wheel 321, thereby launching the aircraft 1 to be launched. The trigger switch realizes accelerated launch.

[0073] like Figure 2 As shown, the feeding transmitter frame 31 is also equipped with an infrared aiming device 310. The infrared aiming device 310 is located at the upper end of the emission port and is used to emit infrared laser to illuminate the emission port direction.

[0074] The above settings allow for adjustment of the firing direction of the firing port. The infrared laser emitted by the infrared sight 310 can be used to determine the firing direction, making it easy to observe whether the firing point is aligned with the firing location and achieve long-range target hit.

[0075] In the above structure, when the aircraft 1 is ready to launch, it is stored at the rear end of the launch channel 5 within the feeding and launching module 3. Side limiting plates 341 and side limiting brackets are installed on both sides of the feeding mechanism 33 in the launch channel 5 to conform to the aircraft 1 and limit the feeding direction. Upper guide rails 343 and lower guide rails 344 are installed on the upper and lower sides of the launcher mechanism in the launch channel 5 to conform to the aircraft 1 and limit the launch direction. The output of the rotation adjustment motor 23 in the base rotation adjustment module 2 rotates, driving the drive gear 25 to rotate. The drive gear 25 meshes with the rack plate 25, moving along the arc of the rack plate 25. This movement of the drive gear 25 drives the rotation adjustment motor 23 to move, simultaneously driving the rotation adjustment... The motor mounting plate 28 and the frustum turntable 22, which are fixedly connected to the motor 23, rotate on the base 21 along the circumference of the frustum turntable 22. The height adjustment motor 41 in the height adjustment module 4 drives the output end to rotate, which in turn drives the height adjustment screw coupling 43 to rotate. The height adjustment screw coupling 43 drives the height adjustment screw 42 to rotate. The height adjustment screw 42 and the adjusting screw nut 45 form a screw-nut transmission. The adjusting screw nut 45 moves along the axial direction of the height adjustment screw 42 nut, which drives the linkage fixing plate 49 on the screw nut seat 46 to move along the length direction of the linear guide 47. When the linkage fixing plate 49 moves, it drives the support rod 40 on the linkage fixing plate 49 to move. When the support rod 40 moves, it drives the front part of the transmitter frame 31 to move. Furthermore, because the rear of the transmitter frame 31 is connected to the rear of the support frame 27 by a pin, the height of the front of the transmitter frame 31 can be changed when the rear pin of the transmitter frame 31 is fixed, thereby adjusting the launch height and direction quickly. In the feeding and launching module 3, the output of the feeding motor 331 rotates, driving the feeding screw coupling 332 to rotate. The feeding screw coupling 332 then drives the loading screw 338 to rotate. The rotation of the loading screw 338 causes the feeding screw nut 339 to move axially along the loading screw 338. The rotation of the loading screw 338 causes the feeding push plate to move towards the launching mechanism 32. Simultaneously, the loading optical shaft 351 located on one side of the loading screw 338 increases the stability of the movement of the feeding push plate. The feeding push plate 337 carries... The lower feeding plate 330 at the bottom of the motor pushes the aircraft 1 along the launch channel 5 toward the launch mechanism 32. After the friction wheel 321 in the launch mechanism 32 is accelerated to a specified speed by the acceleration motor 322, the feeding push plate 337 pushes the aircraft 1 to be launched into the launch mechanism 32. The two sides of the aircraft 1 rub against the friction wheel 321. The aircraft 1 is accelerated and launched under the action of the friction wheel 321. The overall feeding speed is fast. After the previous aircraft 1 is launched, the next aircraft 1 can be pushed to the launch mechanism 32 for launch immediately. The launch direction can be adjusted by the base rotation adjustment module, and the launch height can be adjusted by the height adjustment module 4, so as to launch the aircraft 1 in multiple directions and at multiple heights. The operation is simple.

[0091] (3.5) When the support rod moves, it will drive the front part of the transmitter frame to move, and the height of the front part of the transmitter frame will change, thereby completing the adjustment of the launch height.

[0093] (4.1) The output end of the feeding motor rotates, driving the feeding screw coupling to rotate;

[0094] (4.2) The feeding screw coupling drives the filling screw to rotate;
