In the intelligent aiming firearm system, a series of links including marking of a target point, real-time tracking of the target point, automatic sensing of ballistic parameter environment, automatic calculation of ballistic trajectory, establishment of final firing opportunity and the like are automatically controlled and completed by a whole set of electronic system. The firing link of the shooting is taken as the final and most important link of the whole shooting process, and the research and development requirements of the electronic control firing system component are particularly urgent. In the existing electronic control firing solutions, mostly an electromagnet or a motor is used to apply a force to a trigger, so as to implement automatic trigger firing, and similar technologies are referred to chinese patents CN201407955Y, CN103591834A, CN203642786U, CN106871712A, and the like.
Analysis shows that the electric control firing systems have many advantages, but have some disadvantages and shortcomings: 1) In the whole process that a shooter finishes shooting and firing by using the electronic control firing systems, from the aspect of ergonomics, the systems do not fully consider the normal shooting habit of being compatible with common firearms; 2) Most of the electric control firing systems do not meet the requirement of manual firing under the condition of system power failure or emergency; 3) The existing electronic control firing system has longer response delay time of firing, because the existing system mainly depends on the action force generated by the rotation of an electromagnet and a motor to trigger a trigger to complete firing action, and the whole firing process is complicated and consumes longer time from the time of receiving an electronic firing instruction to the time of completing the action of triggering the trigger, which is generally more than 200 milliseconds;
4) The existing electric control firing system lacks monitoring and feedback of trigger action, so that the safety of shooting is reduced; 5) The existing electric control firing system needs to drive a trigger to complete firing by means of strong electromagnetic force or motor traction force, so that an electromagnet assembly or a motor assembly with a large volume and strong power supply need to be matched, and great test is brought to the installation and power supply of the matched whole gun.

The spanner is connected with the firing lever and then fixed on the gun body, and the spanner is buckled to drive the firing lever to move, so that a linked trigger assembly is formed. The photoelectric sensor is fixed on the gun body and is positioned on the motion path of the firing lever, so that the position and the state of the wrench are indirectly monitored and fed back to the microprocessor.

Furthermore, the electromagnetic assembly comprises an electromagnet, a thimble and a shaft sleeve, the shaft sleeve is fixed on the gun body, the electromagnet is fixed at the bottom of the shaft sleeve, and the thimble is movably arranged in the shaft sleeve. After the electromagnet is electrified, magnetic force (magnetic repulsion force) is generated to push the thimble to be contacted with the end part of the firing lever, so that the firing lever is blocked from continuing to move, and a spanner linked with the thimble cannot be buckled (corresponding to a pre-firing state and position); increasing the force for buckling the wrench, continuously moving a firing lever linked with the wrench, forcibly pushing the thimble to retract into the shaft sleeve by overcoming the electromagnetic resistance to finish firing (corresponding to the forced firing under emergency); after the electromagnet is powered off, the magnetic force disappears, and the wrench is buckled to continue moving to finish the percussion (corresponding to normal percussion).

Detailed Description
In order to make those skilled in the art fully understand the technical solutions and advantages of the present invention, the following description is further provided with reference to the specific embodiments and the accompanying drawings.
In the present invention, the orientations (e.g., upper, lower, left, right, front, and rear), etc. are all shown in the drawings.
An electric control firing system for firearms as shown in fig. 1 mainly comprises a wrench 1, a firing lever 2, an electromagnetic assembly 3, a photoelectric sensor 4, a microprocessor, a power supply and a sighting telescope, which are all directly or indirectly fixed on the surface or inside of a gun body.
The power supply supplies power for all electric equipment including an electromagnetic component, a photoelectric sensor, a microprocessor, a sighting telescope and the like, and a battery box or a battery compartment device developed earlier by the company can be selected, specifically refer to Chinese patents CN109346635B, CN111009630A, CN110416461A and the like.
The gun body is fixed in the gun sight installation, and the shooter passes through the eyepiece and observes, aims at the target, and camera or the synchronous collection target image of detector in the gun sight simultaneously handles, then transmits for microprocessor, and microprocessor further handles data and judges whether coincidence of visual field center and identification point to whether the decision is assigned the firing instruction. The intelligent sighting telescope carried by the invention can select related patent products disclosed earlier by the company, such as Chinese patents CN112180551A, CN112180550A, CN112099179A and the like.
The wrench 1 and the firing lever 2 are fixed in the gun body through screws to form a trigger assembly. For common firearms on the market at present, the shooting process is often as follows: the shooter firstly uses the sighting telescope to observe a locked target, then fingers touch the wrench 1 with force to drive the firing lever 2 to rotate around the rotating shaft, so that one side of the firing lever is high and the other side of the firing lever is low (high at the left and low at the right), and the raised end of the firing lever is tilted to push the firing pin 8 to complete firing and shooting. The present application is different in that on the basis of keeping the original trigger assembly, a plurality of (3 in fig. 1) photoelectric sensors, a set of electromagnetic assemblies and at least one microprocessor for analyzing and processing data and controlling each part are additionally arranged on the periphery of the trigger assembly.
Specifically, three photoelectric sensors 4 are respectively arranged on the motion paths of the front end, the top end and the middle and rear ends of the trigger lever 2, and are used for monitoring the motion track of the trigger lever in real time and further determining the position and the corresponding state of the wrench 1 linked with the trigger lever. As shown in fig. 2-3, wrench 1 has three positions a-c corresponding to an initial position, a pre-firing position, and a firing position. When the hand wrench is fired, the firing lever rotates around the shaft, different photoelectric sensors may change between shielding and non-shielding (corresponding to the high level and low level), and an electric signal (such as a voltage change signal) generated by the photoelectric sensors is input into the microcontroller, so as to control the on/off of the electromagnetic assembly. The electromagnetic assembly is arranged right above the left end of the firing lever 2 and comprises a shaft sleeve 7, an electromagnet 6 fixed at the end part of the shaft sleeve 7 and a thimble 5 which is sleeved in the shaft sleeve 7 and can move up and down. The electromagnet 6 generates magnetic force after being electrified, and pushes the thimble 5 to extend out of the shaft sleeve and contact with the firing lever to prevent the thimble from continuing to move (indirectly preventing the shooter from continuing to buckle the wrench leftwards). When the electromagnet is powered off suddenly and the magnetic force disappears instantly, the shooter can easily continue to buckle the wrench to complete the percussion (corresponding to c in fig. 2). In order to deal with emergencies or emergencies, the b state of the magnetic force preventing the percussion can be forcibly struck, only the shooter needs to buckle the wrench with larger force, and when the acting force reaches a preset critical value and is enough to break through the magnetic resistance force, the electromagnet is powered off instantly, and the magnetic force disappears.
In conclusion, the electric control firing system of the firearm comprises three states and two firing modes, and the specific firing process is as follows: the whole system is powered on, a shooter can shoot after preparing, and the wrench is located at the initial position a; the shooter observes the locked target through the sighting telescope, the image collected by the sighting telescope is processed and then transmitted to the microprocessor, and the microprocessor judges whether the center of the view field is superposed with the identification point or not; if the signals are superposed, the aim is indicated, the microprocessor controls the electromagnet to break and not generate magnetic force, and the shooter can buckle the wrench to directly move from the position a to the position c for shooting; if the target is not coincident, the microprocessor controls the electromagnet to be communicated to generate magnetic force for blocking the movement of the firing lever, and the firing hand-operated wrench can only move to the position b unless aiming at the locking target again to ensure that the center of the view field is coincident with the identification point; when the spanner is in the position a or the position b, and the shooter only needs to push the spanner with force to break the magnetic resistance force when shooting is necessary in an emergency, and the shooting can be finished.
