[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically a one-to-four throwable smoke-generating UAV. Background Technology

[0002] With the advancement of technology and the development of society, even in peacetime, weaponry, as the most powerful equipment for defending the homeland and the people, still needs vigorous development. Smoke grenades are important equipment for covert attacks and battlefield cover. Traditional smoke grenades usually rely on manual throwing or launch vehicles for firing, such as the smoke-generating vehicle with controllable smoke grenade trajectory disclosed in Chinese utility model patent application number CN202322724912.0. However, both manual throwing and launch vehicle firing have problems such as limited application scenarios, poor operational flexibility, and high exposure risk. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a one-to-four throwable smoke-generating drone, which solves the problems of existing smoke grenades usually relying on manual throwing or launching vehicles, resulting in limited application scenarios, poor usage flexibility, and high exposure risks.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A one-to-four throwable smoke-generating drone includes a drone body, a mounting bracket connector, a mounting bracket body, a telescopic connection module, a drive component, and a smoke-generating projectile.

[0006] The main body of the mounting bracket is connected to the bottom of the drone body via a mounting bracket connector. The main body of the mounting bracket has several connection ends, each of which has an installation structure. The drive component is located inside the installation structure, with its output end facing downwards and connected to the rotating pull ring of the smoke bomb. The upper end of the telescopic connection module is connected to the installation structure, and the smoke bomb is clamped at the lower end of the telescopic connection module. When the drive component drives the rotating pull ring of the smoke bomb to rotate into place, the telescopic connection module drives the smoke bomb to move downwards to release the safety mechanism.

[0007] Furthermore, the telescopic connection module includes a release bracket, a connecting column, a limiting component, a compression spring, and an assembly cylinder;

[0008] The upper end of the assembly cylinder is connected to the mounting structure. The outer wall of the assembly cylinder is provided with a limiting groove along the vertical direction. The upper end of the connecting column is inserted into the assembly cylinder from the bottom. The limiting component is connected to the upper end of the connecting column, and the limiting component and the limiting groove are slidably assembled together. The compression spring is located between the upper end of the connecting column and the inner top wall of the assembly cylinder. The release bracket is connected to the lower end of the connecting column, and the bottom of the release bracket forms a projectile clamping groove, in which the smoke projectile is clamped.

[0009] Furthermore, the limiting component is a limiting screw that is threadedly connected to the upper end of the connecting column.

[0010] Furthermore, the main body of the bracket has a cross-shaped structure.

[0011] Furthermore, the main body of the bracket and the bracket connector are detachably connected.

[0012] Furthermore, the mounting bracket includes a bracket body, a torsion spring, and a torsion spring pressure block; the bracket body is connected to the bottom of the UAV body, and assembly grooves are formed on both sides of the bottom of the bracket body. A connecting guide rail is provided on the top of the mounting bracket body, and the connecting guide rail is slidably connected to the assembly grooves; a hinge seat is formed at one bottom end of the bracket body between the two assembly grooves, and the torsion spring pressure block is hinged to the hinge seat through the torsion spring. A limit hook is formed at one end of the torsion spring pressure block, and a limit hook groove is formed on the top of the connecting guide rail. The limit hook is hooked into the limit hook groove under the action of the torsion spring.

[0013] Furthermore, the connector body is detachably connected to the bottom of the drone body.

[0014] Furthermore, the driving component is a servo motor, and the output end of the servo motor is provided with a connector, to which the rotating pull ring of the smoke-generating projectile is connected.

[0015] Furthermore, the main body of the drone is a quadcopter drone.

[0016] Furthermore, the mounting structure is integrated with the main body of the bracket, and both the mounting structure and the main body of the bracket are made of carbon fiber composite material.

[0017] By adopting the above-described technical solution of this utility model, at least the following beneficial effects are achieved:

[0018] 1. The modular mounting design allows the drone to carry the smoke projectiles to the desired destination before dropping them, and multiple smoke projectiles can be carried simultaneously. Therefore, compared with the existing manual throwing or launch vehicle method, it can better adapt to various usage scenarios, has greater flexibility, and is more concealed, effectively reducing the risk of exposure.

[0019] 2. The main body of the pylon can be detachably connected to the pylon connector at the bottom of the UAV body. During the assembly and disassembly process, only the torsion spring block needs to be pressed. This allows for the quick replacement of the main body of the pylon and the smoke projectiles as a whole according to the actual mission requirements. This not only improves the battlefield adaptability of the equipment, but also significantly shortens the mission preparation time.

[0020] 3. The installation structure is designed to be integrated with the main body of the bracket, and both the installation structure and the main body of the bracket are made of carbon fiber composite materials. This can effectively reduce the overall weight while ensuring structural strength, thereby extending the endurance of the smoke-generating drone and enabling it to carry more payload or cover a wider mission area.

[0021] 4. It has multi-mode delivery capability. It can select to deliver one or multiple smoke projectiles at the same time according to actual needs, or allow the smoke projectiles to fall freely to the ground to release smoke, or allow the smoke drone to carry the smoke projectiles to continuously release smoke in the air. This significantly improves the diversity of tactical options and the flexibility of use. Attached Figure Description

[0036] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] Please see the appendix Figures 1 to 6 As shown, this utility model provides a one-to-four throwable smoke-generating drone 100, which includes a drone body 1, a hanger connector 2, a hanger body 3, a telescopic connection module 4, a drive component 5, and a smoke-generating projectile 6.

[0038] The main body 3 of the mounting bracket is connected to the bottom of the main body 1 of the UAV via the mounting bracket connector 2, so that the main body 1 of the UAV can drive the main body 3 to fly together. The main body 3 of the mounting bracket is provided with several connection ends 31, and each connection end 31 is provided with an installation structure 32. The drive component 5 is located inside the installation structure 32, which can specifically serve as an outer protective shell for the drive component 5, thus protecting the drive component 5. The output end of the drive component 5 faces downward and is connected to the rotating pull ring 61 of the smoke bomb 6. The upper end of the telescopic connection module 4 is connected to the installation structure 32, and the smoke bomb 6 is clamped at the lower end of the telescopic connection module 4. When the drive component 5 drives the rotating pull ring 61 of the smoke bomb 6 to rotate into place, the telescopic connection module 4 drives the smoke bomb 6 to move downward to release the safety. In this invention, the smoke bomb 6 uses a rotating pull ring 61. During use, the rotating pull ring 61 needs to be rotated 180° to release the restriction. Therefore, this invention connects the output end of the drive component 5 to the rotating pull ring 61 of the smoke bomb 6, so that the drive component 5 automatically drives the rotating pull ring 61 to rotate. Simultaneously, the smoke bomb 6 is clamped at the lower end of the telescopic connecting module 4, and the upper end of the telescopic connecting module 4 is connected to the mounting structure 32. This allows the smoke bomb 6 to automatically detach from the lower end of the telescopic connecting module 4 and fall downwards under the elastic force of the telescopic connecting module 4 and its own gravity after the drive component 5 drives the rotating pull ring 61 to rotate to the desired position and release the restriction. Since the rotating pull ring 61 is connected to the output end of the drive component 5, it will disengage from the smoke bomb 6 during its descent, thus releasing the safety mechanism and allowing the smoke bomb 6 to release smoke.

[0039] Please refer to the following embodiments of this utility model. Figure 4 and Figure 5As shown, the telescopic connection module 4 includes a release bracket 41, a connecting column 42, a limiting component 43, a compression spring 44, and an assembly cylinder 45;

[0040] The upper end of the assembly cylinder 45 is connected to the mounting structure 32 to meet the support requirements of the assembly cylinder 45 through the mounting structure 32; the outer wall of the assembly cylinder 45 is provided with a limiting groove 451 along the vertical direction; the upper end of the connecting column 42 is inserted into the assembly cylinder 45 from the bottom; the limiting component 43 is connected to the upper end of the connecting column 42, and the limiting component 43 is slidably assembled with the limiting groove 451 to limit the up and down movement of the connecting column 42; the compression spring 44 is located between the upper end of the connecting column 42 and the inner top wall of the assembly cylinder 45, and the compression spring 44 is in a compressed and stored state after assembly; the release bracket 41 is connected to the lower end of the connecting column 42, and the bottom of the release bracket 41 forms a projectile clamping groove (not shown), in which the smoke projectile 6 is clamped. In specific implementation of this utility model, in order to ensure that the upper end of the connecting column 42 can be reliably limited, at least two limiting grooves 451 can be provided on the outer wall of the assembly cylinder 45 along the vertical direction, and a limiting component 43 is provided on the upper end of the connecting column 42 corresponding to each limiting groove 451, and each limiting component 43 is slidably assembled with a limiting groove 451.

[0041] In practical operation, the telescopic connecting module 4 of this utility model can provide the following two operational modes: First, when the driving component 5 drives the rotating pull ring 61 to rotate into position to release the restriction, the compression spring 44 will drive the connecting column 42, the release bracket 41, and the smoke bomb 6 to move downwards rapidly together. During this process, the rotating pull ring 61 will disengage from the smoke bomb 6 to release the safety, allowing the smoke bomb 6 to release smoke. At the same time, under the elastic force of the compression spring 44 and its own gravity, the smoke bomb 6 will detach from the release bracket 41 and fall to the ground to continue releasing smoke. Smoke; The second type, which differs from the first combat mode, uses metal cable ties or the like to fix the smoke projectile 6 to the safety release bracket 41. In this second combat mode, when the compression spring 44 drives the connecting column 42, the safety release bracket 41, and the smoke projectile 6 to move downwards rapidly together, the rotating pull ring 61 will disengage from the smoke projectile 6 to release the safety. However, the smoke projectile 6 will not disengage from the safety release bracket 41 due to the restriction of the metal cable ties or the like. Therefore, after the safety is released, the smoke projectile 6 can continuously release smoke in the air under the drive of the smoke drone 100.

[0042] In one specific embodiment of this utility model, the limiting component 43 is a limiting screw threadedly connected to the upper end of the connecting column 42. Of course, the above is only one specific embodiment of this utility model, but it is not limited to this. In specific implementations, other limiting components can be used according to actual needs, as long as they can limit the upper end of the connecting column 42.

[0043] As a specific embodiment of this utility model, the main body 3 of the bracket has a cross-shaped structure, that is, the entire main body 3 of the bracket has 4 connecting ends 31. In this way, during actual use, the smoke-generating drone 100 can carry 4 smoke-generating projectiles 6 at one time for flight. When dropping, it can select one smoke-generating projectile 6 to be dropped according to actual needs, or it can select multiple smoke-generating projectiles 6 to be dropped at the same time.

[0044] In one specific embodiment of this utility model, the mounting structure 32 is integrated with the hanging bracket body 3, and both the mounting structure 32 and the hanging bracket body 3 are made of carbon fiber composite material, which can effectively reduce the overall weight while ensuring structural strength.

[0045] In one specific embodiment of this utility model, the main body 3 of the hanging bracket is detachably connected to the hanging bracket connector 2 so that the main body 3 of the hanging bracket can be disassembled and separated during use.

[0046] Please refer to the following embodiments of this utility model. Figure 6As shown, the mounting bracket 2 includes a bracket body 21, a torsion spring 22, and a torsion spring pressure block 23. The bracket body 21 is connected to the bottom of the UAV body 1. Assembly grooves 211 are formed on both sides of the bottom of the bracket body 21. A connecting guide rail 33 is provided on the top of the mounting bracket body 3, and the connecting guide rail 33 is slidably connected to the assembly grooves 211. A hinge seat 212 is formed at one bottom end of the bracket body 21 between the two assembly grooves 211. The torsion spring pressure block 23... The torsion spring 22 is hinged to the hinge seat 212. In a specific implementation of this utility model, a shaft (not shown) can be set on the hinge seat 212, and the torsion spring pressure block 23 and the torsion spring 22 are both sleeved on the shaft, and the torsion spring 22 is connected to the torsion spring pressure block 23. One end of the torsion spring pressure block 23 forms a limiting hook part 231, and the top of the connecting guide rail 33 forms a limiting hook groove 331. The limiting hook part 231 is hooked into the limiting hook groove 331 under the action of the torsion spring. In practical use, when it is necessary to disassemble the main body 3 of the hanger and the hanger connector 2, simply press the torsion spring block 23 to make the limiting hook 231 leave the limiting hook groove 331, and pull the connecting guide rail 33 outwards to the end away from the torsion spring block 23 to separate the main body 3 of the hanger and the hanger connector 2. During assembly, simply push the connecting guide rail 33 along the assembly slide groove 211 and make the limiting hook 231 hook into the limiting hook groove 331.

[0047] In some embodiments of this utility model, the connector body 21 is detachably connected to the bottom of the drone body 1, so that the connector body 21 can be disassembled when needed. In specific implementations of this utility model, the connector body 21 can be locked together with the bottom of the drone body 1 by screws or bolts.

[0048] In one specific embodiment of this utility model, the driving component 5 is a servo motor, and the output end of the servo motor is provided with a connector 51. The rotating pull ring 61 of the smoke bomb 6 is connected to the connector 51. During operation, the servo motor drives the connector 51 to rotate, and the connector 51 then drives the rotating pull ring 61 to rotate. In a specific implementation of this utility model, the connector 51 and the rotating pull ring 61 of the smoke bomb 6 can be detachably connected, so that the rotating pull ring 61 can be disassembled and separated from the connector 51 later.

[0049] In one specific embodiment of this utility model, the drone body 1 is a quadcopter drone body. Because the smoke-generating drone 100 of this utility model carries multiple smoke projectiles 6 during actual use, the drone body 1 is designed as a quadcopter drone body to ensure reliable power supply for flight.

[0050] In summary, by adopting the above-described technical solution of this utility model, at least the following beneficial effects are achieved:

[0051] 1. The modular mounting design allows the drone body 1 to carry the smoke projectile 6 to the desired destination before dropping it. Multiple smoke projectiles 6 can be carried simultaneously. Therefore, compared with the existing manual throwing or launch vehicle method, it can better adapt to various usage scenarios, has greater flexibility, and is more concealed, effectively reducing the risk of exposure.

[0052] 2. The main body 3 of the mounting bracket is detachably connected to the mounting bracket connector 2 at the bottom of the main body 1 of the UAV. During the disassembly and assembly process, only the torsion spring pressure block 23 needs to be pressed. This allows the main body 3 of the mounting bracket and the smoke-generating projectile 6 to be quickly replaced according to the actual mission requirements during use. This not only improves the battlefield adaptability of the equipment, but also significantly shortens the mission preparation time.

[0053] 3. The installation structure 32 is designed to be integrated with the main body 3 of the bracket, and both the installation structure 32 and the main body 3 of the bracket are made of carbon fiber composite material. This can effectively reduce the overall weight while ensuring structural strength, thereby extending the endurance of the smoke-generating UAV and enabling it to carry more payload or cover a wider mission area.

[0054] 4. It has multi-mode delivery capability. It can select to deliver one or multiple smoke projectiles 6 at the same time according to actual needs. It can also allow the smoke projectiles 6 to fall freely to the ground to release smoke, or allow the smoke drone 100 to carry the smoke projectiles 6 to continuously release smoke in the air. This significantly improves the diversity of tactical options and the flexibility of use.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
