Please refer to FIGS. 1-3 , the patent of the present invention provides a technical solution; an automatic locking system for a revolver, including a control module, a mechanical locking block 5 , a pistol grip module and a smart watch 8 . The mechanical locking block 5 is inserted into the rotating shaft of the micromotor 4 in the control module, and the rotating shaft of the micromotor drives the mechanical locking block to rotate to realize the unlocking/locking of the pistol; according to the structural design, a hole is reserved in the grip module, and the mechanical locking module 5 and the control module are installed together in the grip module; the control module and the smart watch 8 establish a communication link through the Bluetooth chip to realize the reception and feedback of the unlocking/locking command.

The control module includes a main control single chip microcomputer chip 1, a bluetooth chip 2, a lithium battery 3 and a micro motor 4. The RX (receiving end) and TX (sending end) pins of bluetooth chip 2 are connected with the TX (sending end) and RX (receiving end) pins of main control single-chip microcomputer chip 1 respectively, and the STATUS (status) pin of bluetooth chip 2 is connected with an enabling pin of main control single-chip microcomputer chip; Make a common ground connection.

Among them, the main control single-chip microcomputer chip 1 has multiple analog interfaces and digital interfaces, and at the same time, it also has a USB Type-C interface, which can be used to supply power, download codes and receive signals. Through programming, the control program of the automatic locking system of the revolver is designed in the single chip microcomputer.

The bluetooth chip 2 is used to pair with the smart watch 8, and will receive the signal from the watch and transmit it to the receiving end of the main control single-chip microcomputer chip 1 through the sending end, so as to realize the rotation control of the micro motor 4. The status terminal of the Bluetooth chip 2 is connected to the enabling pin of the main control microcontroller chip 1. When the Bluetooth is connected normally, the status terminal of the Bluetooth chip 2 outputs a high level. When the Bluetooth is disconnected, the status terminal of the Bluetooth chip 2 outputs a low level. The connection status of Bluetooth is fed back through the high and low level signals. When the level is low, the main control single-chip microcomputer chip 1 will execute the locking command to realize self-locking when disconnected. Considering the power consumption and battery life of the entire module, the Bluetooth chip 2 uses a low-power Bluetooth module, and the battery uses a large-capacity rechargeable battery, which can be charged by connecting an external power source through the USB Type-C port of the main control microcontroller to improve the battery life of the traditional locking module. Under normal use, it can reach 5-6 hours of battery life, which is enough to meet most usage situations.

The micro-motor 4 includes a DC motor, a reduction gear set, an angle sensor and a control circuit; specifically as shown in Figure 6,

Wherein the control circuit receives the control signal of the main control microcontroller 1, and drives the DC motor to rotate; the DC motor is connected to the input shaft of the gear set, and drives the gear set to rotate; the gear set is used to double the speed of the motor and double the output torque of the motor, and then output the torque; the output shaft of the gear set rotates with the angle sensor, and the angle sensor transmits the rotation angle of the gear set output shaft to the control circuit in real time, and controls the rotation of the output shaft of the gear set to the target angle or maintains it at the target angle through feedback, so as to mechanically lock 5 rotation angles, limit the hammer lever 10 or give way Give Hammer Rod 10. Wherein the output shaft of the gear set is used as the rotating shaft of the micro motor 4 .

Described mechanical locking piece 5 is provided with mounting hole, and mounting hole size is identical with micromotor 4 rotating shaft sizes; Mechanical locking piece 5 is fixedly connected with 4 rotating shafts of micromotor through mounting hole, drives mechanical locking piece 5 rotations when micromotor 4 rotates. In the locked state, the mechanical locking block 5 is placed at the lower end of the hammer spring bar 10, so that the hammer spring bar 10 cannot continue to move downwards for firing; in the unlocked state, the micro-motion motor 4 drives the mechanical locking block 5 to rotate, leaving the lower end position, and the hammer spring bar 10 can move downwards for firing. Among them, the mechanical locking block 5 is made of 3D printing photosensitive resin, which satisfies the mechanical strength and is lighter in weight, lower in cost and more comfortable to hold than traditional metal, and does not interfere with Bluetooth signal transmission.

The pistol grip module includes the left grip 6 and the right grip 7 of the revolver 9; the main control single-chip microcomputer chip 1 and the Bluetooth chip 2 are loaded into the right grip 7 with a slot of a specific shape, the lithium battery 3, the micromotor 4 and the mechanical locking block 5 are loaded into the left grip 6 of the revolver with a slot of a specific shape, the left grip 6 and the right grip 7 of the revolver 9 are connected by screws and nuts, and the grip is made of photosensitive resin 3D printing.

The smart watch is paired and connected with the main control single-chip microcomputer chip 1 through Bluetooth. Through program development, the smart watch 8 can display the unlocked/locked status of the pistol in real time on the watch panel. At the same time, combined with the positioning function and heart rate detection function of the smart watch 8, it can realize the detection and reporting of the user's status information. Simultaneously smart watch 8 is provided with buzzer, is used for starting alarm function when gun is lost.

The communication protocol between the smart watch 8 and the main control single-chip microcomputer chip 1 in the automatic locking system of a revolver designed by the present invention includes control commands and status return information. The message contains 5 bytes, including frame header, frame length, command word, data, and frame tail. For example, {0XAA, 0X05, 0X01, 0X01, 0XB5} means unlock command. While unlocking and locking, the MCU will also give real-time status information feedback, for example {0XAA, 0X05, 0X06, 0X06, 0XB7} means the pistol has been unlocked, and the panel of the smart watch 8 can display the status of the pistol at this time.

Working principle: In the automatic locking system of the revolver, the Bluetooth chip 2 is first paired with the smart watch 8, and after receiving the unlock/lock signal from the smart watch 8, the PWM (pulse width modulation) terminal of the main control microcontroller 1 outputs a corresponding level signal, and the micro-motor 4 receives the level signal to rotate. In the locked state, the mechanical locking block 5 is placed at the lower end of the hammer spring bar 10, so that the hammer spring bar 10 cannot continue to move downwards for firing; in the unlocked state, the micro-motion motor 4 drives the mechanical locking block 5 to rotate, leaving the lower end position, and the hammer spring bar 10 can move downwards for firing.

A control method of the automatic locking system of a revolver involved in the present invention is shown in Figure 7, and its specific steps are:

Step 1: Determine the user authorization status; unauthorized users will limit their access rights, and authorized users can log in to the system through passwords;

Step 2: When the user is authorized, the smart watch 8 performs vital signs detection, electronic fence detection, and device identification detection on the user; when the user has vital signs, the location is within the preset electronic fence range, and the smart watch 8 is connected to the Bluetooth chip 2, the pistol can be controlled. If one or more of the three are not satisfied, a warning will be issued and the pistol equipment will be locked;

Specifically, the system detects the status of the pistol equipment in real time and reports the status. The smart watch 8 detects the heart rate every minute. When the user loses the vital sign information, the system will issue a warning and issue a locking command to lock the pistol; the program terminal of the main control chip will pre-measure the Bluetooth RSSI (received signal strength indicator) value at a specified distance and set it as a threshold value. When the Bluetooth exceeds this distance and disconnects, the system will also issue a warning and issue a locking command to lock the pistol.
