Description

Trigger driving limiting mechanism for unmanned aerial vehicle mounted gun

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 trigger drive stop gear for unmanned aerial vehicle mounted gun.

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 107963215 a discloses a rotor-armed drone, which prior art mentions that the weapon carried by the drone may be a grenade launcher, rifle or rocket launcher, 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.

As shown in fig. 1, a schematic structural diagram of the drone 100 with the gun mounted thereon according to an embodiment of the present application shows that a gun mount 500 for mounting the gun 200 is disposed below the drone 100, and the gun mount 500 may be directly connected to the belly of the drone 100 or mounted below the drone 100 through an extension mount 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.

The gun 200, regardless of the manner in which it is mounted below the drone 100, needs to address how the gun 200 fires to fire. Thus, as shown in fig. 2, the present application further provides a trigger actuation mechanism 400 for actuating a trigger of a gun 200 mounted below a drone 100 by a 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 application is how to fire the gun 200 mounted on the unmanned aerial vehicle, and thus the present application is not limited to the gun mount 500 of the specific structure shown in fig. 2, and as long as the gun 200 can be mounted below the unmanned aerial vehicle 100, the trigger driving mechanism 400 of the present application can drive the trigger of the gun 200 also supported on the gun mount 500 by means of the support of the gun mount 500.

Fig. 2 shows a structural schematic diagram of a trigger driving mechanism 400 for a gun mounted by a drone according to an embodiment of the present application connected to a gun mount 500, and fig. 3 and 4 are installation schematic diagrams of the trigger driving mechanism 400 with a partial structure removed step by step on the basis of fig. 2, 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 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.

Further, fig. 5 is an exploded perspective view of a trigger driving mechanism for a gun mounted by an unmanned aerial vehicle according to another embodiment of the present application, as can be seen from fig. 2 to 5, the trigger driving mechanism 400 of the present application 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 installed on the adjustable hanger 402, and a head of a driving shaft 404 of the electromagnet 403 can drive a transverse lever 405 inserted into a trigger retainer 205 of the gun 200 to move 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. 4-5, 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. 3, 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. 5, 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.

Because the armed unmanned aerial vehicle of this application generally can attack the flight in the far away scope of sight distance, the rifle 200 on unmanned aerial vehicle 100 though can very reliable fire or put out a fire under the condition of electro-magnet 403 break-make, in case of accident, the condition that trigger 204 is blocked to the dead appears, remote control personnel are unknown, if the trigger blocks to be in the state of lasting percussion, unmanned aerial vehicle sails back and will directly attack oneself, this will become very dangerous, though this kind of situation can not take place basically, nevertheless in case of with the defense, this application provides a stop gear 600, a position for coordinating trigger actuating mechanism 400 and detecting trigger 204, as safety precaution measure.

Still referring to fig. 5, the spacing mechanism 600 of the present application includes a spacing piece 4071 connected to the driving shaft 404 of the electromagnet 403 and a spacing sensor 408 corresponding to the position of the spacing piece 4071. In the illustrated embodiment, the limiting piece 4071 is formed by integrally extending an end of the lateral operating frame 407 opposite to the lateral operating rod 405, but the limiting piece 4071 may be a structure independent from the lateral operating frame 407. The limit sensor 408 is supported on the adjustable hanger 402 by a sensor mounting plate 491. In order to avoid the space occupied by the outward extending limiting sheet 4071 being too large, in the illustrated embodiment, a bending structure 4073 facing the electromagnet is integrally formed between the lateral acting frame 407 and the limiting sheet 4071, so that the volume of the mounting plate 491 of the limiting sensor 408 can be reduced to a certain extent. Of course, if the installation space is not limited, the stopper 4071 may extend laterally directly from the lateral actuating frame 407. Through the position change of the limit piece 4071 relative to the limit sensor 408, an electric signal related to the position can be generated in the set stroke range, so that whether the driving shaft 404 is in the fired state or in the unfired state can be known, and the remote operator can know whether the trigger is in the fired state or the unfired state exactly. The following is a more specific example.

As shown, in one embodiment, the limit sensor 408 includes two mechanical limit switches 4081, and the limit tab 4071 moves between the two mechanical limit switches 4081, and the maximum and minimum strokes of the limit tab 4071 are detected by touching the two mechanical limit switches 4081. That is, when the electromagnet 403 is powered on, the limiting piece 4071 moves backwards to the minimum stroke position along with the driving shaft 404 of the electromagnet 403, the trigger 204 is pushed to the bottom, the machine gun 200 is in the firing state, at this time, the limiting piece 4071 touches a mechanical limiting switch 4081 in the backward direction, the mechanical limiting switch 4081 generates an electric signal and transmits the electric signal to the control device in a wireless manner, so that the control device can know that the trigger 204 is pushed to the bottom under the power-on condition, and the situation of jamming does not occur. Conversely, when the electromagnet 403 is de-energized, the driving shaft 404 will extend forward and reset, and the limit piece 4071 will move to the maximum travel position and will contact a mechanical limit switch 4081 in the forward direction, and the electrical signal generated by the mechanical limit switch 4081 will inform the operator that the trigger 204 has been reset, and the gun 200 is not fired and is in the flameout state.

Further, the present application provides another limit sensing manner, that is, in another embodiment shown in the drawings, the limit mechanism 600 of the present application includes a magnet 4072 mounted on a limit piece 4071, the limit sensor 408 includes two hall switches 4082, the limit piece 4071 carries the magnet 4072 to move between the two hall switches 4082, and the maximum stroke and the minimum stroke of the limit piece 4071 are detected by magnetic induction. Similar to the mechanical limit switch, the embodiment changes the touch manner of the mechanical limit switch into the magnetic induction manner of the magnet and the hall switch, and the general working principle thereof is similar to that of the mechanical limit switch, so that those skilled in the art can easily understand the mechanical limit switch in an extended manner, and further description is omitted for saving space.

Furthermore, in another embodiment of the present application, the limiting mechanism 600 of the present application may include a mechanical limiting system including a limiting piece 4071 and two mechanical limiting switches 4081, and a magnetic induction system including a magnet 4072 and two hall switches 4082 mounted on the limiting piece 4071, that is, in the embodiment shown in the figure, the limiting mechanism 600 of the present application may serve as a dual-safety limiting sensor by two sets of limiting systems, as long as the electrical signal sent by any one set of limiting system can be received, the state of the trigger can be determined, the problem of uncontrollable risk of the weapon system caused by sensor failure in a severe environment is avoided, and the safety of the weapon system of the present application is ensured.

It should be appreciated by those skilled in the art that while the present application is described in terms of several embodiments, not every embodiment includes only a single embodiment. The description is thus given for clearness of understanding only, and it is to be understood that all matters in the embodiments are to be interpreted as including all technical equivalents which are encompassed by the claims and are to be interpreted as combined with each other in a different embodiment so as to cover the scope of the present application.

The above description is only illustrative of the present invention and is not intended to limit the scope of the present invention. Any equivalent alterations, modifications and combinations that may be made by those skilled in the art without departing from the spirit and principles of this application shall fall within the scope of this application.
