Description

Technical Field

[0001] The present invention relates to the technical field of foldable drones, and in particular to a device and method for powering on a barrel of a barrel-launched foldable drone. Background Art

[0002] Folding drones can fold their components together using a folding mechanism, effectively reducing their size and enabling launch or deployment from a variety of weapon platforms. By integrating with ammunition technology, they can perform single or multiple tasks, including environmental reconnaissance, precision strikes, target location, remote guidance, and damage assessment. They offer low cost, high cost-effectiveness, compact size, and ease of use. Compared to traditional drones, folding drones can be launched or deployed intensively from a variety of weapon platforms, forming rapid swarm deployments. They can also be deployed by individual soldiers across various military branches, quickly entering combat zones, demonstrating strong penetration capabilities and flexible tactical deployment. Compared to conventional ammunition or fixed-wing drones, they offer superior low-speed flight performance, greater adaptability to complex urban environments, and greater advantages in detecting and attacking concealed and sensitive targets.

[0003] Folding drones can be launched from the ground, from the palm of your hand, by hand, or by canister launch. The first three methods require the drone to be unfolded before takeoff, hindering rapid deployment. Canister launch effectively solves this problem. Currently, canister-launched folding drones are still in the research stage and have some practical drawbacks. For example, power-on startup typically involves connecting the drone's power battery to the avionics connector outside the canister. After powering up the drone, the drone is then loaded into the launch canister and awaits launch, making the preparation process complex and inconvenient.

[0004] The Chinese patent publication number CN213735526U discloses a large-load micro-cannon-launched folding quad-rotor drone. During use, the drone needs to be powered on and started outside the launch tube as described above, and then loaded into the launch tube. Such an operation is cumbersome for single-person use and even unacceptable for a cluster system. Chinese patents CU209274879U and CN210149542U respectively disclose a barrel-type folding-wing drone and describe its use process, but neither of them provides any description of how the folding-wing drone completes the system power-on startup. In summary, there is a technical gap in the rapid and convenient power-on startup of the current barrel-type launched folding drone that needs to be addressed. Summary of the Invention

[0005] To address the shortcomings of existing technical solutions and improve the efficiency and convenience of powering on foldable canister-launched drones, the present invention provides a device and method for powering on foldable canister-launched drones from within the canister.

[0019] The wireless power supply coil is fixed outside the transmitting tube, and the wireless power supply coil can transmit wireless power to the wireless power receiving coil;

[0020] The energy supply control circuit board is electrically connected to the wireless energy supply coil and can control the operation of the wireless energy supply coil. The energy supply control circuit board is fixed outside the transmitting tube.

[0021] Furthermore, the micro power-on switch is fixed in a special-shaped hole at the rear end of the body of the folding drone; and the wireless power-on piston cooperates with the special-shaped hole surface of the folding drone.

[0022] Furthermore, the upper structural member of the piston is provided with a boss, which is used to perform form fit with the hole at the rear end of the body of the foldable drone.

[0023] Furthermore, the piston lower structure has a circumferential groove for receiving the wireless energy receiving coil; the wall of the piston lower structure has a through hole for the wire of the wireless energy receiving coil to pass through.

[0024] Furthermore, the piston lower structure has a recess for receiving the piston upper structure.

[0025] Furthermore, the in-barrel power-on device for the barrel-type launching foldable drone also includes a limiting member, which is fixed in the launching barrel to limit the position of the wireless power-on piston in the launching barrel.

[0052] The present invention is described in detail below with reference to the accompanying drawings and embodiments. Examples of these embodiments are shown in the accompanying drawings. The same or similar reference numerals throughout represent the same or similar elements, which have the same or similar functions. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0053] The invention provides a device for powering up a foldable unmanned aerial vehicle in a barrel and a method for powering up a foldable unmanned aerial vehicle in a barrel.

[0054] First refer to Figure 1 and Figure 2 The in-barrel power-on device for a barrel-type launching foldable UAV provided by the present invention is described in detail. Figure 1 This is a schematic stereoscopic diagram of the docking between the wireless power-on piston in the power-on device in the barrel of a barrel-launched folding drone and the folding drone according to an exemplary embodiment of the present invention. Figure 2 It is a schematic three-dimensional diagram of a wireless energy supply device in a power-on device inside a barrel of a barrel-launched folding drone, a launching barrel, and a gas generator according to an exemplary embodiment of the present invention.

[0055] See also Figure 1 and Figure 2 As an exemplary embodiment of the present invention, the power-on device inside the barrel of a barrel-type launching folding drone may include a wireless power-on piston 1, a wireless energy supply device 2, and a micro power-on switch 3.

[0056] like Figure 1 and Figure 2As shown, the wireless energy supply device 2 is fixedly installed outside the launch tube 5 for accommodating the foldable drone 4, and can drive the wireless power-up piston 1 to move.

[0057] The wireless power-on piston 1 can be formed to mate with the folding drone 4 and can be installed together into the launch tube 5 after mating. The wireless power-on piston 1 is used to press the micro power-on switch 3 after the wireless power supply device 2 supplies energy to complete the power-on start of the folding drone 4 in the tube.

[0058] Depend on Figure 1 As can be seen, the micro-switch 3 can be fixed in the body of the foldable drone 4. When the wireless power supply device 2 drives the wireless power-on piston to move, the wireless power-on piston can press the micro-switch 3. In the illustrated embodiment of the present invention, the micro-switch 3 is fixed in a hole at the rear end of the body of the foldable drone 4, and the wireless power-on piston 1 cooperates with the hole surface of the foldable drone 4.

[0059] Now refer to Figure 3A and Figure 3B The wireless power-on piston in the power-on device in the barrel of the barrel-launched folding drone provided by the present invention is described in detail. Figure 3A It is an exploded perspective view of a wireless power-up piston in a power-up device in a barrel of a barrel-launched folding drone according to an exemplary embodiment of the present invention. Figure 3B It is an assembly cross-sectional view of a wireless power-up piston in a barrel-launched folding drone power-up device according to an exemplary embodiment of the present invention.

[0060] See also Figure 3A and Figure 3B In the illustrated embodiment of the present invention, the wireless power-on piston 1 may include a power-on cam 101, a piston upper structure 102, a starting motor 103, a starting motor control circuit board 104, a piston lower structure 105 and a wireless energy receiving coil 106.

[0061] The power-on cam 101 is used to press the micro-power-on switch 3 to complete the in-tube power-on start of the folding drone 4. In some embodiments, the power-on cam 101 has a central hole for passing the output shaft 1031 of the starter motor 103.

[0062] The piston upper structure 102 is generally disc-shaped and is capable of mate-fitting with the folding drone 4. The piston upper structure 102 has a central hole 1021 for passing the output shaft 1031 of the starter motor 103. The piston upper structure 102 may be provided with a disc-shaped portion 1022 and a boss 1023. The boss 1023 is configured to mate with the hole at the rear end of the folding drone 4 to ensure the correct loading position when the folding drone 4 is inserted into the launch tube 5. By way of example and not limitation, the hole at the rear end of the folding drone 4 for securing the micro-switch 3 may be a special-shaped hole. In this case, the boss 1023 has a shape corresponding to the special-shaped hole of the folding drone 4. Preferably, the boss 1023 may be polygonal in shape, and the corresponding hole at the rear end of the folding drone 4 has a shape corresponding to the polygon.

[0063] The output shaft 1031 of the starter motor 103 passes through the center hole 1021 of the piston upper structure 102 and is capable of driving the power-on cam 101 to rotate. Specifically, the power-on cam 101 is sleeved onto the output shaft 1031 of the starter motor 103 and rotates together with the output shaft 1031. Furthermore, the power-on cam 101 is axially spaced a certain distance from the piston upper structure 102 to prevent the piston upper structure 102 from interfering with the movement of the power-on cam 101.

[0064] The starter motor control circuit board 104 is used to control the operation of the starter motor 103 .

[0065] The piston lower structure 105 is generally cylindrical in shape and has an inner cavity 1051 for receiving the starter motor 103 and the starter motor control circuit board 104. Figure 3B As shown, the starter motor control circuit board 104 is located at the bottom of the inner cavity 1051 , and the starter motor 103 is fixed on the starter motor control circuit board 104 .

[0066] The upper piston structure 102 is connected to the lower piston structure 105. In some embodiments of the present invention, the lower piston structure 105 may have a recess 1052 for receiving the disc-shaped portion 1022 of the upper piston structure 102. In addition, corresponding threaded holes are arranged on the disc-shaped portion 1022 of the upper piston structure 102 and the recess 1052 of the lower piston structure 105 for connecting the upper piston structure 102 to the lower piston structure 105 via screws. The number of threaded holes is not limited. For example, in the illustrated embodiment, the number of threaded holes is four.

[0067] The wireless energy receiving coil 106 is sleeved on the piston lower structure 105 and is electrically connected to the starter motor control circuit board 104 . The wireless energy receiving coil 106 can perform wireless energy transmission with the wireless energy supply device 2 .

[0068] In an optional embodiment of the present invention, the piston lower structure 105 may have a circumferential groove 1053 for receiving the wireless power receiving coil 106. In some embodiments, the wireless power receiving coil 106 may be attached to the circumferential groove 1053 of the piston lower structure 105 by glue. It should be noted that any type of glue known to those skilled in the art may be used.

[0069] In some embodiments, the wall of the piston lower structure 105 may have a through hole 1054 for a wire 1061 of the wireless power receiving coil 106 to pass through, thereby achieving an electrical connection between the wireless power receiving coil 106 and the starter motor control circuit board 104. Furthermore, the wire 1061 may be soldered to the starter motor control circuit board 104.

[0070] Now refer to Figure 2 and Figure 4 The wireless energy supply device in the power-on device inside the barrel of the barrel-type launching folding drone provided by the present invention is described in detail. Figure 4 It is a schematic three-dimensional diagram of the in-barrel power-up device of a barrel-launched folding drone in a standby state according to an exemplary embodiment of the present invention.

[0071] Return to reference Figure 2 In the illustrated embodiment of the present invention, the wireless power supply device 2 may include a wireless power supply coil 201 and a power supply control circuit board 202 .

[0072] like Figure 4 As shown, after the wireless power-on piston 1 and the foldable drone 4 are matched and installed together in the launch tube 5, the wireless power supply coil 201 is fixed outside the launch tube 5, and the wireless power supply coil 201 can wirelessly transmit power to the wireless power receiving coil 106. In the illustrated embodiment of the present invention, the wireless power supply coil 201 can be mounted on the outside of the bottom end of the wall of the launch tube 5.

[0073] The power supply control circuit board 202 is electrically connected to the wireless power supply coil 201 and can control the operation of the wireless power supply coil 201. The power supply control circuit board 202 is fixed outside the transmitting tube 5. In some embodiments of the present invention, the power supply control circuit board 202 can be fixed to the bottom of the transmitting tube 5.

[0074] See also Figure 4 When the power-on device inside the barrel of the barrel-type launching folding drone according to the present invention is in a standby state for the folding drone 4 to be launched, the gas generator 6 can be fixed in the launching barrel 5 and contact the energy supply control circuit board 202 to launch the folding drone 4 in the launching barrel 5.

[0075] In a preferred embodiment of the present invention, Figure 4As shown, the barrel-launched foldable drone in-barrel power-up device may further include a stopper 7, which is fixed in the launch barrel 5, particularly to the inner wall of the launch barrel 6 in the launch barrel 5, to limit the position of the wireless power-up piston 1 in the launch barrel 5. In some exemplary embodiments, the stopper 7 is annular in shape and rectangular in cross-section, but this is not intended to be limiting. For example, the stopper 7 may be one or more protrusions, as long as it can limit the position of the wireless power-up piston 1 in the launch barrel 5.

[0076] Now refer to Figure 5A and Figure 5B The method for powering on a foldable drone in a barrel provided by the present invention is described in detail. Figure 5A It is a schematic plan view of a power-on cam and a micro power-on switch in a power-on device in a barrel of a barrel-type launching folding drone according to an exemplary embodiment of the present invention, in a non-contact state. Figure 5B It is a schematic plan view of a power-on cam and a micro power-on switch in a power-on device in a barrel of a barrel-type launching folding drone according to an exemplary embodiment of the present invention, in a contact state.

[0077] Reference Figures 1 to 5B As an exemplary embodiment of the present invention, a method for powering up a foldable drone in a barrel may include the following steps:

[0078] a) A micro-switch 3 is provided in the body of the foldable drone 4. Specifically, the micro-switch 3 is fixed in a special-shaped hole at the rear end of the body of the foldable drone 4.

[0079] b) Connect the wireless power-on piston 1 to the foldable drone 4 through a positive fit, so that the wireless power-on piston 1 can press the micro-power switch 3 when in motion. In particular, the wireless power-on piston 1 is connected to the foldable drone 4 by the positive fit of the boss 1023 on the piston upper structure 102 of the wireless power-on piston 1 and the special-shaped hole at the rear end of the foldable drone 4. At this time, Figure 5A As shown, the power-on cam 101 of the wireless power-on piston 1 does not make contact with the power-on micro switch 3 .

[0080] c) Load the foldable drone 4 and the wireless power-on piston 1 into the launch tube 5 for accommodating the foldable drone 4. In particular, when loading, when the wireless power-on piston 1 contacts the stopper 7, it indicates that the foldable drone 4 and the wireless power-on piston 1 are loaded in place.

[0081] d) The wireless power supply device 2 is fixedly mounted outside the launch tube 5 so that it can drive the wireless power piston 1. Specifically, the wireless power supply device 2 is mounted so that the non-powered power supply coil 201 of the wireless power supply device 2 is axially aligned with the wireless power receiving coil 106 of the wireless power piston 1, thereby preparing for power-on activation of the foldable drone 4 during launch.

[0082] e) Power the wireless power supply device 2 to drive the wireless power-on piston 1 to move and press the micro-power-on switch 3, thereby completing the power-on start of the folding drone 4. In particular, the power supply control circuit board 202 of the wireless power supply device 2 is energized, and the starter motor control circuit board 104 of the wireless power-on piston 1 receives power through the wireless power receiving coil 106 and the non-powered power supply coil 201 of the wireless power supply device 2 to start the operation and drive the output shaft 1031 of the starter motor 103 of the wireless power-on piston 1 to rotate one circle, thereby driving the power-on cam 101 to rotate, especially along the Figure 5A Rotate in the direction of the arrow in the figure. Figure 5B When the foldable drone 4 is in the position shown, the power-on cam 101 contacts and presses the power-on micro switch 3 , thereby completing the power-on of the foldable drone 4 inside the tube.

[0083] It should be pointed out that the order of the above steps is only exemplary, and the above steps of the method for powering on a barrel of a barrel-launched folding drone of the present invention can be performed in other orders. For example, step d) can be implemented before step c).

[0084] According to the present invention, the in-barrel power-up device and method for launching a foldable drone from a canister canister can be directly stored in the launch canister when unpowered, enabling long-term storage. When the foldable drone needs to be launched and powered on, there's no need to remove the drone from the launch canister. Instead, the wireless power supply device located outside the launch canister is powered on from the outside. The wireless power-up piston then generates electromagnetic induction through the wireless power supply coil in the wireless power supply device and the wireless power receiving coil in the wireless power-up piston, driving the wireless power-up piston's drive motor to rotate one revolution. This in turn drives the power-up cam to rotate, pressing the micro-power-up switch, thereby quickly powering up the foldable drone within the canister. This in-barrel power-up device and method for launching a foldable drone from a canister canister requires no additional mechanical components and is suitable for foldable drones with limited size and mass. The power-up operation is independent of the drone's own power source, allowing the foldable drone to be stored in the launch canister for extended periods in an unpowered state. This allows for efficient and rapid power-up and launch for a single user, as well as for the unified, efficient, and large-scale deployment of clustered, canister-launched foldable drones.

[0085] The above embodiments merely illustrate the implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
