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, does not disclose a machine gun as any standard weapon, may be a completely new design, and the cost and reliability remain uncertain, 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 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 large number of pictures of the gun can be obtained through internet inquiry by those skilled in the art.
As shown in fig. 2, the gun 200 has a butt 203 at the rear of the body, and the body has other structures such as a trigger 204 for firing, a trigger guard 205, and a safety guard 206 for preventing the gun from firing by an erroneous operation. The stock is a component commonly used on various types of machine guns, the safety guard 206 is a rod-shaped structure penetrating through a gun body, and the machine guns can be locked or unlocked by pressing two ends of the safety guard 206. That is, by depressing one end of the safety guard 206 from one side of the body, the other end of the safety guard 206 will protrude from the other side of the body, and by depressing different ends of the safety guard 206 from different sides of the body, the machine gun can be locked or unlocked. Such push-type safes are also commonly used in the art of machine guns.
The gun 200 is mounted below the drone 100 by any method, and the control problem of the gun 200 is solved: the manipulation of the safety 206 unlocks and the trigger 204 is then manipulated to fire the gun 200 for firing. Thus, as shown in fig. 3, the present application further provides a safety drive mechanism 700 and a trigger drive mechanism 400 for operating the safety 206 on the gun body to lock or unlock the gun, and then operating the trigger of the gun 200 mounted below the drone 100 by the gun mount 500 to fire the gun 200.
It should be understood by those skilled in the art that the technical problem to be solved by the present embodiment is the problem of how to operate the safety 206 of the gun 200 mounted on the drone and how to operate the trigger 204 to fire, and therefore the present application is not limited to the gun mount 500 with the specific structure shown in fig. 3, and as long as the gun 200 can be mounted under the drone 100, the safety driving mechanism 700 and the trigger driving mechanism 400 of the present application can drive the safety 206 and the trigger 204 of the gun 200 that are also supported on the gun mount 500 by the support of the gun mount 500.
The driving mechanism for the unmanned aerial vehicle gun of the present application, including the safety driving mechanism 700 and the trigger driving mechanism 400, is described in further detail below to illustrate how the driving mechanism of the present application unlocks or locks the safety 206 and fires the trigger 204 to fire the gun 200.
Fig. 3 is a schematic view showing an installation of a driving mechanism for a gun mounted on an unmanned aerial vehicle according to an embodiment of the present application, in which a safety driving mechanism 700 and a trigger driving mechanism 400 are shown, connected to a gun hanger 500, and fig. 4 is a schematic view showing an installation of the safety driving mechanism 700 and the trigger driving mechanism 400 with a partial structure removed on the basis of fig. 3. The safety drive mechanism 700 may be used to operate the safety 206 to lock or unlock the gun 200 mounted below the drone 100. The trigger drive mechanism 400 may be used to operate the trigger 204 of the gun 200 mounted below the drone 100 to fire the gun 200. It can be seen that the trigger drive 400 of the present application is integrally attached to the gun hanger 500 and a transverse lever 405 of the trigger drive 400 is inserted into the trigger retainer 205 of the gun 200 and moves back and forth to release or actuate the trigger 204, i.e., when the transverse lever 405 moves backward, the transverse lever 405 acts like a finger to actuate the trigger 204 backward to fire the gun 200 and to fire the fire, and when the transverse lever 405 moves forward, the release trigger 204 stops firing.
The driving operation of the fuse 206 is first explained below.
It should be noted that the security 206 can be manually released in advance by the drone before the ground takeoff. However, in the event of a problem with handling, such as a crash during takeoff, it is possible for the unsecured gun to fire violently during the crash; or an accident occurs when the unmanned aerial vehicle with the bullet returns to the field, the gun without the safety lock can be fired against the self, and the consequences are very serious. Therefore, from the aspect of safety, it is preferable that after the unmanned aerial vehicle flies to the attack position, the insurance is opened through remote control, and after the attack is finished, the insurance is locked through remote control.
Fig. 5 is a schematic view of the installation of the safety driving mechanism 700 of fig. 4 with a part of the structure removed. It can be seen that the safety drive mechanism 700 of the present application is integrally supported on the gun hanger 500. in the illustrated embodiment, the safety drive mechanism 700 is integrally supported between two hanger plates of the gun hanger 500. the linear motor 705 for driving is fixedly mounted on the inside of one hanger plate of the gun hanger 500. the linear motor 705 can drive a pressing rod 703 to press the safety 206 to lock or unlock the gun 200.
Further, fig. 6 is an exploded perspective view illustrating a safety driving mechanism for a machine gun of an unmanned aerial vehicle according to another embodiment of the present application, as can be seen from fig. 3 to 6, the safety driving mechanism 700 of the present application includes a fixing shaft 701 supported above the machine gun 200 in a straddling manner by a machine gun hanger 500, two control arms 702 respectively disposed at two sides of the machine gun 200 are penetrated on the fixing shaft 701, pressing rods 703 for pressing the safety 206 are respectively disposed on the two control arms 702, a spacer sleeve 704 is fixedly clamped between the two control arms 702, and the two control arms 702 and the spacer sleeve 704 are driven by a linear motor 705 connected to the machine gun hanger 500 to move leftwards or rightwards along the fixing shaft 701, so as to drive the pressing rods 703 to respectively press the right end or the left end of the safety 206, thereby locking or unlocking the machine gun 200.
Taking the gun shown in fig. 4 as an example, when the linear motor 705 retracts, the right pressing rod 703 presses the right end of the safety guard 206, and when the linear motor 705 is locked at this time, the left pressing rod 703 presses the left end of the safety guard 206, and at this time, the locking is released. As regards the direction of locking or unlocking, it is also possible to reverse the above assumptions, which are merely illustrative of the principle, and the skilled person can choose to lock the machine gun to the left or to the right depending on the actual situation of the different machine guns. In one embodiment, the linear motor 705 may be a conventional linear telescopic push-pull rod type linear motor, such as a CNXCI 758 base planar dc push-rod motor, available from fast electric company limited, le qing, with a maximum push force of 12 kg.
According to the characteristics of the linear motors sold by different manufacturers, for example, a treasure house searching the internet through a keyword linear motor control chip, a plurality of motor drive chips which can be used for controlling the forward and reverse rotation of the linear motor can be found by a person skilled in the art, so that two different level signals can be provided for the linear motor through a control signal sent remotely to control the forward and reverse rotation of the linear motor, and finally the linear motor is extended or retracted. In a specific embodiment, an MC33932VW control chip of shenzhen san yi electronics technology limited may be adopted to be mounted on the drone to control the extension and retraction of the linear motor.
Further, as shown in the figure, a driving end 706 of the linear motor 705 is fixedly connected with an actuating arm 707, the actuating arm 707 penetrates through the fixing shaft 701 and is fixedly connected with any one of the control arms 702, and the linear motor 705 can drive the control arm 702 to move left and right along the fixing shaft 701 through the actuating arm 707.
In the illustrated embodiment, the actuator arm 707 is clamped between two actuator arms 702, and both actuator arms 707 and actuator arms 702 are fixedly connected to the two ends of the spacer sleeve 704 by screws. Spacer sleeve 704 is generally in the form of a circular sleeve, and the illustration shows that spacer sleeve 704 has removed a portion of the wall because the installation space constraints require avoidance and removal of a portion of the structure, and need not be designed to have such a shape if the installation space is sufficient.
In yet another embodiment, the pressing rod 703 is rotatably connected to the operating arm 702 by a pin 708, the pressing rod 703 has a positioning groove 709, the operating arm 702 is provided with a knob plunger 710 corresponding to the positioning groove 709, and the pressing rod 703 can be fixed in a horizontal state for pressing by the cooperation of the knob plunger 710 and the positioning groove 709. Knob plungers are a very common snap-on connection, and the details of which can be found by those skilled in the art by web search, for example by panning. The knob plunger 710 is fixedly connected with the control arm 702 through the thread of the head, and the head can be retracted against the internal elastic force by pulling out the tail end of the knob plunger 710, the tail end of the knob plunger 710 is loosened, and the head can be extended again. In one embodiment, the knob plunger 710 can be a precision knob plunger model VCN213-CB-M8 sold by Shenzhen Weiqi.
Since the stroke of pressing the safety guard 206 to the left and right is only about a few millimeters, the two pressing rods 703 are disposed close to the body of the gun for response sensitivity, and when the gun 200 needs to be detached from or attached to the drone 100, the gun 200 is difficult to pass through the gap between the two pressing rods 703 if the pressing rods 703 are in a horizontal state as shown for pressing. Therefore, in the above embodiment, the pressing rod 703 is rotatably connected, and by pulling out the knob plunger 710, the head of the knob plunger 710 is separated from the positioning groove 709, the pressing rod 703 can rotate around the pin 708 to a sagging state, so that a large space is obtained for the machine gun to pass through. The above-mentioned connection structure of the present application has the advantages that the pressing rod 703 is always connected to the pin 708, the pressing rod 703 is only rotated around the pin 708 and does not fall off the manipulating arm 702 and is not lost, and the pressing rod 703 is positioned to the horizontal state and is not separated from the manipulating arm 702 due to the special structure of the knob plunger 710 although it is locked by the knob plunger 710, so that the pressing rod 703 can be conveniently rotated by hands or positioned to the working state, and the operation is very simple.
Further, in the illustrated embodiment, linear bearings 711 are also provided in both actuating arms 702, which are also fixedly connected to both ends of the spacer sleeve 704 by screws together with the actuating arms 702. The linear bearing 711 ensures that the two operating arms 702 do not become offset jammed or excessively worn.

The operation of the actuation of trigger 204 is further described below with reference to fig. 7-8.
Fig. 7 is a schematic view of fig. 4 with a portion of the trigger driving mechanism 400 removed, and fig. 8 is an exploded perspective view of a trigger driving mechanism for a gun of an unmanned aerial vehicle, according to another embodiment of the present invention, as seen in fig. 7-8, the trigger driving mechanism 400 of the present invention includes a fixed hanger 401 connected to a gun hanger 500, an adjustable hanger 402 is connected to the fixed hanger 401, an electromagnet 403 is mounted on the adjustable hanger 402, and 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 a 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. Of course, 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 gun hanger 500. Of course, since the technology of the electromagnet is well-established, a person skilled in the art can easily customize the square electromagnet as shown in the drawings of the present application by an electromagnet manufacturer according to the required maximum attraction force.
As shown in fig. 7-8, since the width of the machine gun hanger 500 for installing the fixed hanger 401 is limited, an annular structure 4011 is provided 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 structure on which the gun hanger 500 can be mounted is too narrow, it is difficult to provide a space in which the position of the adjustable hanger 402 can be adjusted, and therefore, four long holes 4012 in which the position of the adjustable hanger 402 can be adjusted are provided on the mounting 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 case of power failure of the electromagnet 403, the elastic reset mechanism 406 can push the head of the driving shaft 404 out of the attraction state, so as to ensure that the transverse control rod 405 connected with the driving shaft 404 is returned to the release state from the firing state, and at this time, the machine gun 200 will be shut down along with the power failure of the electromagnet 403, so as to ensure that the machine gun operation is ensured to be safe.
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 shown in FIG. 4, 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. 8, an adapter 490 can 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 can be eliminated 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 utility model provides an above-mentioned trigger drive structure is the brand-new structure of an independent research and development, and its structural feature according to current machine rifle can realize the percussion and the stopping fire of machine rifle through the circular telegram outage of electro-magnet, controls simply, provides the precaution of avoiding the jam moreover, can not appear being difficult to the incident of percussion or being difficult to the stopping fire, has high reliability and security.
