Description

A machine rifle carry and trigger drive structure for unmanned aerial vehicle

Technical Field

The application relates to the technical field of unmanned aerial vehicles, especially relates to an armed unmanned aerial vehicle with weapon, in particular to a gun mounting and trigger driving structure for unmanned aerial vehicle.

Background

The unmanned plane is called unmanned plane for short, and is an unmanned plane operated by radio remote control equipment and a self-contained program control device. Unmanned aerial vehicles can be classified into military and civil applications according to the application field. For military use, unmanned aerial vehicles are classified into reconnaissance aircraft, target aircraft, and armed unmanned aerial vehicles that have gained popularity in recent years. The civil unmanned aerial vehicle is widely applied to the fields of aerial photography, agriculture, plant protection, miniature self-timer, express transportation, disaster relief, wild animal observation, infectious disease monitoring, surveying and mapping, news reporting, power inspection, disaster relief, movie and television shooting and the like.

Armed drones of the prior art are typically used as missile launching platforms that are too expensive to combat small-strand terrorists. The artillery or gun is installed on one type of manned armed helicopters, but the artillery or gun integrated with the airframe on the armed helicopters is mostly a specially designed product, or the existing artillery or gun is installed on an airplane after being modified, and is different from weapons equipped by soldiers. Inheriting the thought, some existing armed unmanned aerial vehicles can also use the thought for reference, namely, specially designed guns or guns are arranged on the unmanned aerial vehicles, so that the use cost of airborne weapons is reduced.

Even so, however, there are not many examples of such armed drones that mount special firearms. For example, CN 204021248U discloses a riot-proof drone, which although carrying a machine gun, discloses a machine gun which is not like any standard weapon, may be a completely new design, and the cost and reliability are not questionable, and it is not evident from the prior art how the machine gun is carried under the drone. For another example, CN 206954525U discloses an airborne tower of an unmanned aerial vehicle, and the gun carried on the unmanned aerial vehicle shown in the prior art is also specially designed, and is different from the existing single-soldier standard weapon, so that the reliability needs to be tested for a long time, the redesign and testing costs are very high, and the popularization is difficult. In addition, CN 107963215A discloses a rotor wing armed drone, which prior art mentions that the weapon carried by the drone may be a grenade launcher, rifle or rocket launch canister, the preferred weapon being a grenade launcher. From the point of view of the construction of the connecting weapon provided by this prior art, which provides only a small cylinder around the barrel, the connection is very secure, the stability of the connection appears to be very big, and the prior art does not mention how to keep the barrel from backing out of the small cylinder in the event of recoil. In addition, the preferred weapon of this prior art is a grenade launcher with low launch speed, which has low reliability requirements on the attachment structure, and thus provides an attachment structure that is not suitable for high firing rate and high recoil guns.

In a word, current armed unmanned aerial vehicle, the weapon of the mount that it provided mostly needs special design, and reliability and cost are difficult to control, hardly persuade the customer and accept newly-designed weapon. The prior art also does not provide a reference structure for existing mature weapons such as machine guns that can be mounted.

In addition, the above prior art does not disclose any technical solution related to the control of the machine gun on which the unmanned aerial vehicle is mounted.

Detailed Description

In order to more clearly understand the technical features, objects, and effects of the present application, embodiments of the present application will now be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.

Fig. 1 shows a schematic structural diagram of the unmanned aerial vehicle 100 with the gun mounted thereon according to an embodiment of the present application, and the present application provides a gun hanger 500 that can be used for mounting the gun 200 below the unmanned aerial vehicle 100, wherein the gun hanger 500 can be directly connected to the belly of the unmanned aerial vehicle 100, or mounted below the unmanned aerial vehicle 100 through an extension hanger 300, as shown in fig. 1. The illustrated drone 100 is a multi-rotor drone, although those skilled in the art will appreciate that the drone 100 is not limited to rotorcraft, but may be a fixed-wing drone, a gas-powered drone, or an electric drone, without limitation.

Further, fig. 2 shows a schematic structural diagram of a gun 200 that can be used to mount on an unmanned aerial vehicle, specifically, the illustrated gun 200 is a model of a milnim M249 gun, and according to factory time and sales area range, the M249 gun has many structural variations, but the basic structure is not very different, and the basic structure of the gun 200 is briefly described below only in a manner suitable for being mounted on the gun hanger 500 of the present application, and a person skilled in the art can query and obtain a large number of pictures of the gun through the internet.

As shown in fig. 2, the gun 200 has a front transverse hole 201 and a middle transverse hole 202 in the front and middle of the gun body, respectively, and a butt 203 in the rear of the gun body, but it also has other structures such as a trigger 204 for firing and firing, and a trigger retainer 205. The front horizontal hole 201 and the middle horizontal hole 202 are two through holes inherent to the M249 gun, and in the following description of the present application, the gun hanger 500 is mounted and connected by the above-described structure of the gun 200. The stock is a common component for each type of gun and the two through holes may be inherent in the illustrated M249 gun, so it will be understood by those skilled in the art that if other types of guns are attached to the gun hanger 500 of the present application, two corresponding through holes, similar to the illustrated M249 gun, are machined in the body that does not relate to the function of the gun, as the front transverse hole 201 and the middle transverse hole 202.

The structure of the gun hanger 500 of the present application will be described in detail with reference to fig. 3-5, wherein fig. 3 and 4 show schematic structural views of the gun 200 of fig. 2 clamped and mounted on the gun hanger 500 for the unmanned aerial vehicle 100 according to an embodiment of the present application from different perspectives; fig. 5 shows an exploded view of a gun mount 500 for a drone 100 according to another particular embodiment of the present application.

As shown in fig. 3-5 in particular, the gun hanger 500 for the unmanned aerial vehicle of the present application may be used to mount the gun 200 below the unmanned aerial vehicle 100, and includes two hanging-up plates 11 arranged in parallel, and the gun 200 is clamped and fixed between the two hanging-up plates 11; the two hanging and carrying plates 11 are connected together through a front bolt 12, a middle bolt 13, an upper spacing frame 14 and a tail spacing frame 15 which are arranged between the two hanging and carrying plates; the front bolt 12 is transversely arranged in the front transverse hole 201 in a penetrating way; the middle bolt 13 transversely penetrates through the middle transverse hole 202; the upper spacing frame 14 is arranged above the gun body of the machine gun 200; the stock 203 is held in the aft frame 15 by threading. In one particular embodiment, as previously described, the top of the mounting plate 11 may be mounted below the drone 100 by an extension pylon 300.

The upper spacing frame 14 and the tail spacing frame 15 have the same width, and can limit the interval between the two hanging and carrying plates 11. The front bolt 12 and the middle bolt 13 can just pass through the two hanging and carrying plates 11 and the front transverse hole 201 and the middle transverse hole 202, and can limit the machine gun 200 to move back and forth and up and down in turn. The aft frame 15 has a holding space (described further below) for holding the butt 203. That is, the gun hanger 500 according to the present invention clamps the gun 200 between the two hanging and supporting plates 11 from three points by the front bolt 12, the middle bolt 13, and the rear spacer 15.

Further, to enhance the lateral clamping action of the machine gun 200, in one embodiment of the present application, two front sleeves 121 are further provided on the front bolt 12 to clamp on both sides of the front lateral hole 201, as shown in the drawings. More specifically, one end face of the front sleeve 121 is inserted into one stepped hole 111 of the mount plate 11, and the other end face abuts on the edge of the front lateral hole 201. By tightening the nuts of the front bolts 12 and clamping the two front sleeves 121, the machine gun 200 can be restrained from rocking left and right along the front bolts 12, and the lateral force for clamping the machine gun 200 is further enhanced.

The stepped hole 111 is provided to facilitate positioning of the front sleeve 121 on the mounting plate 11. When the machine gun 200 is installed, the two front sleeves 121 can be inserted into the stepped holes 111 in advance, but the front bolts 12 are not inserted, so that the front part of the machine gun 200 can partially penetrate through the empty spaces between the ends of the two front sleeves 121 from top to bottom, the wider structural part of the front part of the gun body can be just overlapped on the ends of the two front sleeves 121, and then the front bolts 12 are further inserted to fix the front part of the machine gun 200, and by the structure, only one person is needed to install the front part of the machine gun 200 on the machine gun hanger 500.

To facilitate positioning of the front sleeve 121, the front sleeve 121 and the stepped bore 111 preferably have cooperating non-circular cross-sections that limit rotation of the front sleeve 121. In the particular embodiment shown in the figures, the front sleeve 121 and the stepped bore 111 have a generally rectangular cross-section with chamfered edges to reduce friction of the front sleeve 121 during insertion into the stepped bore 111.

Further, the end of the front sleeve 121 adjacent the front transverse bore 201 is provided with a notch 122 to clear the frame structure of the gun 200, the notch 122 being just useful for catching a wider structural portion of the front of the frame when the gun is installed. By the non-circular cross-sectional design that facilitates positioning in the front, the orientation of the notch 122 can also be positioned exactly, which can reduce the effort of repeatedly adjusting the orientation of the notch 122 during installation.

Similarly, the middle bolt 13 is further provided with two middle sleeves 131 clamped on both sides of the middle transverse hole 202. Similarly, the nut of the middle bolt 13 is tightened, and the machine gun 200 is prevented from shaking left and right along the middle bolt 13 by clamping the two middle sleeves 131, so that the transverse force for clamping the machine gun 200 is further enhanced.

Unlike the front sleeve 121, when the machine gun is mounted, the gun body is held by the front sleeve 121, and the gun is prevented from slipping off only by holding the butt 203 of the machine gun, so the middle part of the machine gun does not need to be positioned, and in order to simplify the structure and cost, the middle sleeve 131 may be a circular sleeve (of course, may be in other shapes) with a relatively simple structure, and only needs one end surface to abut against the side wall of the hanging and carrying plate 11, and the other end surface to abut against the edge of the middle transverse hole 202.

Further, as shown in fig. 5, the aft spacer 15 has a removable shroud 151, and the butt 203 can be accessed into the holding space 152 of the aft spacer 15 by removing the shroud 151. That is, when the gun is mounted, the front part of the gun body is held by the front sleeve 121, the rear part of the gun can be fed into the holding space 152 with the shutter 151 removed by lifting the butt 203, and then the butt 203 can be held by mounting the shutter 151.

Of course, considering the different shapes of the stocks of various guns, the clamping space 152 designed by the present application is not consistent with the structural shape of the illustrated stock 203, and then the stock 203 can be clamped in the clamping space 152 closed by the baffle 151 by wrapping an elastic member (e.g., a silicone pad) on the outer side of the stock 203.

The trigger actuation mechanism of the present application for a firearm of a drone is described in further detail below to illustrate how the present application operates the trigger 204 to fire the firearm 200.

Fig. 6 shows a structural schematic diagram of a trigger driving mechanism 400 connected to a gun hanger 500 for a drone according to an embodiment of the present application, and fig. 7 and 8 are installation schematic diagrams of the trigger driving mechanism 400 with a partial structure removed step by step on the basis of fig. 6, where the trigger driving mechanism 400 can be used to operate a trigger 204 of a gun 200 mounted below a drone 100 to fire the gun 200. It can be seen that the trigger drive mechanism 400 of the present application is integrally attached to the aft spacer 15, and a transverse lever 405 of the trigger drive mechanism 400 is inserted into the trigger retainer 205 of the gun 200 and is movable back and forth to release or actuate the trigger 204, i.e., when the transverse lever 405 is moved rearward, the transverse lever 405 acts like a finger to actuate the trigger 204 rearward to fire the gun 200 and to fire the fire when the transverse lever 405 is moved forward, the release trigger 204 stops firing.

Further, fig. 9 is an exploded perspective view showing a trigger driving mechanism of a gun for an unmanned aerial vehicle according to another embodiment of the present application, and as can be seen from fig. 6 to 9, the trigger driving mechanism 400 of the present application includes a fixed hanger 401 connected to the rear spacer 15 of the gun hanger 500, an adjustable hanger 402 connected to the fixed hanger 401, and an electromagnet 403 mounted on the adjustable hanger 402, wherein a head of a driving shaft 404 of the electromagnet 403 can move a lateral lever 405 inserted into a trigger retainer 205 of the gun 200 back and forth to release or actuate the trigger 204.

Since the gun is a very aggressive weapon, the trigger 204 setting for safety is very aggressive, and therefore a powerful electromagnet 403 is required, which is why the electromagnet 403 is very bulky as illustrated. In one embodiment of the present application, an electromagnet T35105 from electromagnetic science and technology ltd, guan celebration, may be used, the maximum attraction force may be up to 6 kg or more, and the trigger 204 may be pulled to fire the gun 200. Since the attraction force of the electromagnet 403 is large, the volume and weight thereof are also large, and a support member of a reinforcing structure is required to support it on the rear spacer frame 15. Of course, since the technology of the electromagnet is mature, a person skilled in the art can easily customize the square electromagnet as shown in the drawings of the present application by other electromagnet manufacturers according to the required maximum attraction force.

As shown in fig. 8-9, since the width of the fixed hanger 401 for installing the tail spacer 15 on the gun hanger 500 is limited, an annular structure 4011 is disposed in the thickness direction of the fixed hanger 401 to provide a certain extension in the thickness direction, and the space for installing the adjustable hanger 402 is translated for a certain distance to make room for installing the fastener. Meanwhile, since the width of the rear spacer 15 of the gun hanger 500 is too narrow to provide a space in which the position of the adjustable hanger 402 can be adjusted, four long holes 4012 in which the position of the adjustable hanger 402 can be adjusted are provided on the installation wall surface of the fixed hanger 401. The adjustable hanger 402 is a right-angled support with ribs 4021 providing room for the mounting of the electromagnet 403.

The head of the driving shaft 404 on the electromagnet 403 for driving the transverse control rod 405 is thicker and the tail is thinner, and under the condition that the electromagnet 403 is electrified, the head of the driving shaft 404 is sucked and retracted towards the inside of the electromagnet, so that the pulling force for pulling the trigger can be generated, and the machine gun 200 is in a firing state. When the electromagnet 403 is de-energized, the head of the drive shaft 404 will remain in the engaged position if no external force is applied. Of course, since the trigger 204 of the gun 200 has a certain resilience, when the electromagnet 403 is powered off, theoretically, the driving shaft 404 will lose the attraction force, the resilience of the trigger 204 will push the transverse operating rod 405 forward, and then the head of the driving shaft 404 will be pulled out from the attraction position through the transverse operating rod 405, which is a theoretical condition that should appear. However, since the resilience of the trigger 204 is limited, the resilience is very weak after being transmitted to the driving shaft 404 of the electromagnet 403 by the biased leverage of the transverse operating rod 405, and may not be enough to pull the driving shaft 404 out of the attraction position of the electromagnet 403, or is slightly jammed, so that even if the electromagnet 403 is powered off, the driving shaft 404 still remains in the attraction position, the machine gun 200 still remains in the firing state, and at this time, the unmanned aerial vehicle can be operated to return to the home by completely driving bullets in the machine gun, which becomes very dangerous.

To avoid such dangerous situations, in a preferred embodiment of the present application, the tail of the drive shaft 404 is provided with a resilient return mechanism 406 that ejects the head of the drive shaft 404 outward. That is, in the case that the electromagnet 403 is powered off, the elastic reset mechanism 406 can push the head of the driving shaft 404 out of the attraction state, so that the transverse control rod 405 connected with the driving shaft 404 can be ensured to return to the release state from the firing state, and at this time, the machine gun 200 can be stopped as the electromagnet 403 is powered off, and the safe operation of the machine gun can be ensured.

In one embodiment, the resilient return mechanism 406 includes a threaded sleeve 4061 attached to the rear of the drive shaft 404, and a compression spring 4062 is disposed about the threaded sleeve 4061, the compression spring 4062 being stopped at one end by a flange of the threaded sleeve 4061 and at the other end by a stepped bore sleeve 4063.

Further, the stepped hole sleeve 4063 is mounted on the fixed hanger 401, and holes for the threaded sleeve 4061 to move back and forth are provided on the fixed hanger 401 and the adjustable hanger 402, so as to ensure that the back and forth movement of the tail portion of the driving shaft 404 of the electromagnet 403 is not blocked.

Further, a lateral lever 405 is connected to the head of the driving shaft 404 through a lateral operation frame 407; the lateral operating lever 405 is detachably connected to the lateral operating frame 407 by a screw connection. Since the lateral stick 405 needs to be inserted into the trigger retainer 205 of the gun 200, the lateral stick 405 needs to be detachable when the gun 200 is detached from or installed in the drone 100, and thus the lateral stick 405 in the above embodiment of the present application adopts a detachable screw connection.

The lateral operating frame 407 is of a generally plate-like configuration, and its attachment end is configured in a square configuration to facilitate the formation of a threaded hole for the purpose of threadably attaching the lateral operating lever 405. In one embodiment, the lateral motion frame 407 may be directly connected to the head of the drive shaft 404 by fasteners. Of course, in the embodiment of fig. 7 it can be seen that the head of drive shaft 404 is slightly below the cocked position of trigger 204 due to installation space limitations, and therefore in the exploded perspective view of fig. 9, an adapter 490 may be provided between lateral actuating frame 407 and drive shaft 404 to offset the position of lateral actuating frame 407 a distance upward, although this adapter 490 may be omitted altogether if there are no installation space limitations.

Further, since the lateral operating rod 405 transmits the suction force of the driving shaft 404 of the electromagnet 403 to the trigger 204 through the biased leverage, the lateral operating frame 407 connected to the lateral operating rod 405 always tends to push the driving shaft 404 of the electromagnet 403 laterally to one side, which may cause jamming of the driving shaft 404, and in a serious case, the electromagnet may be energized and not fired, or the fire may not be stopped after firing. To solve this problem, in an embodiment of the present application, a guide holder 409 is connected to the lateral actuating frame 407, and a guide rod 410 that is inserted into the guide holder 409 to guide the linear movement of the lateral actuating frame 407 is connected to the housing of the electromagnet 403. Through the cooperation of the guide rod 410 and the guide seat 409, the tendency that the transverse actuating frame 407 deviates to one side can be avoided, and the problem of jamming of the driving shaft 404 is avoided. Furthermore, the guide rod 410 and the guide seat 409 may also have a jamming problem, so that the linear bearing 411 is further installed in the guide seat 409, as shown in the figure, the jamming problem is further avoided by virtue of the advantage that the linear bearing 411 bears strong transverse force.

Above the structure through the electro-magnet drive trigger has been introduced in detail, and unmanned aerial vehicle controls personnel and only needs the remote control electromagnetism iron circular telegram and cuts off the power supply, can realize the percussion of machine gun and open a fire and stop a fire. The above-mentioned trigger actuating mechanism of this application is the brand-new structure of an independent research and development, and its structural feature according to current machine rifle, the percussion that can realize the machine rifle through the circular telegram outage of electro-magnet and stop a fire, controls simply, provides the precaution of avoiding the jam moreover, can not appear being difficult to the incident that the percussion perhaps is difficult to stop a fire, has high reliability and security.
