With reference to these contents, ordinary technicians in this field should be able to understand other possible implementation methods and advantages of the present invention.

[0028] Example 1 This embodiment provides an unmanned aerial platform capable of carrying individual weapons, including: a fuselage 1. Figure 1 As shown, the interior of the fuselage 1 in this embodiment is a hollow structure, and is arranged in a stepped layout to leave a predetermined rotation space for individual weapons. The front top and rear bottom of the fuselage 1 are respectively installed with corresponding front rotor assemblies 2 and rear rotor assemblies 3, which are used to realize the basic flight function of the fuselage 1.

[0029] Furthermore, in order to carry individual weapons and achieve accurate shooting of individual weapons, a rotating mechanism is provided in the hollow structure in this embodiment, and the rotating mechanism is connected to the pan / tilt platform 4 in a transmission manner. The pan / tilt platform 4 is located at the center of gravity of the fuselage 1 and can be combined with the pan / tilt platform 4 to form a rotating mechanism. Figure 1 .

[0030] Furthermore, a rotating mechanism is installed in the pan / tilt 4, and a clamp is connected to the output end of the rotating mechanism, and the clamp is adapted to the individual weapon; the rotating mechanism is configured to control the clamp to have a rotational freedom within an upper and lower angle range in the upper and lower directions of the individual weapon, and the rotating mechanism is configured to control the clamp to have a rotational freedom within a left and right angle range in the left and right directions of the individual weapon, such as Figure 2 The individual weapon may be a firearm, a rocket launcher or other portable individual weapon. Figure 2 And the following uses firearms as an example.

[0031] In order to facilitate storage and transportation, the front rotor assembly 2 and the rear rotor assembly 3 of this embodiment are both foldable. Figure 7 , all of which include: a connecting arm 201, whose connecting end is rotatably connected to a designated position of the fuselage 1; The flying spiral is installed at the end of the connecting arm 201.

[0032] Taking the front rotor assembly 2 as an example, it includes a rotatable connecting arm 201 installed at the front end of the fuselage 1. The flying screw component includes a rotating motor 202 installed at the end of the connecting arm 201, and a propeller 203 installed on the output shaft 6 of the rotating motor 202.

[0033] When the drone needs to be stored or transported, the connecting arm 201 is placed close to the fuselage 1 to reduce the overall volume.

[0034] In order to facilitate the installation of the firearm 5, the firearm 5 of this embodiment includes: a firearm body 501, and an adapter disposed on the back of the firearm body 501. In order to ensure the stability and firmness between the firearm 5 and the platform when rotating in multiple directions, such as Figure 3 As shown, the adapter of this embodiment includes: a protrusion 502 with a predetermined length, and a plurality of protrusions 503 distributed at equal distances on the upper surface of the protrusion 502; the connection between the protrusion 502 and the firearm body 501 is concave to form a positioning groove of a predetermined size; The width of the bump and the width of the bulge The following relations are satisfied: .

[0035] In combination with the above structure, the clamp disclosed in this embodiment includes: a connection frame 504 that is transmission-connected to the rotating mechanism, and a clamp cylinder 505 is disposed in the connection frame 504. The two output ends of the clamp cylinder 505 are correspondingly connected to the clamping member 506. Further, the clamping member 506 is as shown in FIG. Figure 4As shown, it includes: a plurality of clamping plates 506-a distributed at a predetermined distance; the clamping end of the clamping plate 506-a has a positioning block 506-b, and the positioning block 506-b is adapted to the positioning groove; the physical parameters of the clamping plate 506-a satisfy the following relationship: ; in, is the width of the clamping plate, is the distance between adjacent bumps, is the distance between adjacent clamping plates, is the length of the bump.

[0036] When clamping, the clamping plate 506-a is located between adjacent protrusions 503, that is, the protrusions 503 are located between adjacent clamping plates 506-a, to prevent the gun 5 from sliding when tilted. Correspondingly, the positioning block 506-b is located in the positioning groove to ensure that the gun 5 will not slide out of the clamp due to its own weight.

[0037] In order to realize the platform Inner rotation, where The rotation mechanism of this embodiment includes: a rotation power source disposed in the fuselage 1, and a deceleration torque-increasing component whose input end is connected to the rotation power source.

[0038] When the small gear of the deceleration and torque increasing assembly is used as input and the large gear is used as output, the gear transmission system mainly produces the effect of deceleration and torque increasing. This effect enables the transmission system to better adapt to various heavy loads and occasions requiring large torque, and improves the stability and reliability of the mechanical system.

In order to ensure the effect of deceleration and torque increase, the outer tooth diameter of the second bevel gear 9 in this embodiment is larger than the outer tooth second bevel gear 9 of the first bevel gear 7.

[0040] In other words, the pan / tilt head 4 is moved in the forward and reverse directions by rotating the driving motor. The rotation of the scope can meet the angle adjustment when the firearm 5 is fired. A wide range of rotation angles is conducive to increasing the striking range.

[0041] In order to overcome the deviation caused by wind force in the left and right directions of the firearm 5 and the problem of the target object deviating in the left and right directions of the firearm 5, in another embodiment, the rotation mechanism includes: a rotation power source installed on the pan head 4, a driving component whose input end is transmission-connected to the output end of the rotation power source, and a connecting plate 16 arranged at the output end of the driving component.

[0043] The device further comprises a driving gear 17 installed in the pan / tilt head 4 and a driving shaft 15 coaxially connected to the driving gear 17, wherein the driving gear 17 is meshed with the rack 13. The connecting plate 16 is fixedly installed at the end of the driving shaft 15.

[0045] When the drone moves due to wind or other reasons, the gimbal 4 can be used to stabilize the drone and adjust the left and right angles so that the gun 5 is always facing the target.

[0046] Example 2 Based on the unmanned aerial platform capable of carrying individual weapons disclosed in Example 1, this embodiment discloses a flight method for the unmanned aerial platform capable of carrying individual weapons, comprising the following steps: When shooting, the individual weapon is clamped and positioned in the gimbal, that is, the individual weapon is located at the center of gravity of the fuselage; the recoil generated drives the entire fuselage to move backward through the center of gravity, ensuring the stability of the fuselage and the shooting accuracy of the individual weapon; When storing, the front rotor assembly and the rear rotor assembly are folded to reduce the overall volume.

[0047] The following steps are also included: When the target is within the upper and lower angle range of the individual weapon, the fixture is rotated by the revolving mechanism to adjust the shooting angle of the individual weapon within the upper and lower angle range. Furthermore, when the small gear of the deceleration and torque increasing component is used as input and the large gear is used as output, the gear transmission system mainly produces the effect of deceleration and torque increasing. This effect enables the transmission system to better adapt to various heavy loads and occasions requiring large torque, and improves the stability and reliability of the mechanical system.

[0048] When the target is within the left and right angle range of the individual weapon, or the fuselage is offset under the action of external force, the clamp is adjusted by rotating the mechanism to achieve the shooting angle adjustment of the individual weapon within the left and right angle range. The range of rotation is When the drone moves due to wind or other reasons, the gimbal can be used to stabilize the drone and adjust the left and right angles so that the weapon of a single soldier is always facing the target.
