Description

Technical Field

[0001] The invention belongs to the technical field of firearms, and in particular relates to an attached ammunition firing speed regulating device and a working method thereof. Background Art

[0002] Non-lethal weapons are a new concept of weapons that temporarily or permanently disable the normal functions of the target without causing death. They are mainly divided into kinetic strike disablement type, electric shock disablement type and sound and light interference type. Constant kinetic strike belongs to the kinetic strike disablement type, which mainly controls the initial velocity of the bullet to achieve accurate control of the strike kinetic energy of targets at different distances, achieving the goal of non-lethal strike.

[0003] At present, the main ways to achieve constant kinetic energy strikes are pneumatic launch, adding vent holes to the barrel, and electromagnetic launch. The pneumatic launch method requires adjusting the gas pressure, which is time-consuming and inconvenient to operate. The method of adding vent holes is difficult to effectively control because the speed of the projectile in the chamber increases very quickly when the gun is fired. The electromagnetic launch method is difficult to achieve miniaturization and lightness due to technical limitations. Summary of the invention

[0018] 1) First, load the projectile from the rear of the barrel, then rotate the barrel to align with the receiver, and the individual firing holes on the porous shell correspond one by one with the honeycomb electronic ignition head on the control device, and the loading is completed;

[0019] 2) measuring the target distance by a laser rangefinder, and transmitting the target distance information to the control device 3;

[0033] The present invention is further described in detail below with reference to the accompanying drawings and embodiments, but the protection scope of the present invention is not limited thereto.

[0034] Example 1

[0035] like Figure 1-3 As shown, an attached ammunition firing speed regulating device comprises a laser rangefinder 1, a specially-made charge projectile 2, a control device 3, a receiver 4 and a barrel 5.

[0036] The main function of the laser rangefinder 1 is to measure the distance of targets at different distances and display it in real time on the combat panel for users to view, and transmit the target distance information to the control device 3.

[0037] The charged projectile 2 includes a porous shell 21, a propellant charge 22 and a warhead 23, as shown in the figure. Its main function is to meet the needs of different launch energies. The main feature of the porous shell 21 is that there are multiple circular launch holes in a honeycomb shape inside the shell, and the launch holes are not connected to each other. The launch charge 22 is installed inside. By igniting different numbers of launch holes, different amounts of propellant can be switched to obtain different launch energies. The warhead 23 mainly realizes the non-lethal strike function.

[0038] The main function of the control device 3 is to control the emission energy, and it includes a honeycomb electronic ignition head 31, a microelectronic chip 32 and a shell 33. Through the thread and mechanical connection on the shell 33, the internal and external ballistics are solved by the built-in microelectronic chip 32 for different target distances measured by the laser rangefinder 1, and the number of emission holes required for ignition is calculated and the honeycomb electronic ignition head 31 is set. The honeycomb electronic ignition head 31 corresponds to each electronic ignition head on the porous shell 21 one by one, and the ignition action can be implemented for a specific emission hole. Since the weight of the propellant charge contained in each emission hole has been determined, the corresponding projectile exit velocity can be obtained according to the calculation of the built-in microelectronic chip 32 of the control device 3, thereby achieving the purpose of adjusting the projectile exit velocity by controlling energy.

[0039] The receiver 4 and the barrel 5 are common components of firearms, and a control device 3 is installed inside the receiver 4. The barrel 5 can rotate as a whole, exposing the part in contact with the receiver 4 for easy loading. The control device 3 is installed in the receiver 4, the charge projectile 2 is installed in the barrel 5 on the side corresponding to the control device 3, and the laser rangefinder 1 is installed outside the barrel 5 on the side corresponding to the charge projectile 2.

[0040] The working process of the firing speed regulating device is as follows: first, the special charge projectile 2 is loaded from the rear of the barrel 5, and then the barrel 5 is rotated to align with the receiver 4, and each individual electronic ground fire on the porous cartridge case 21 corresponds to the honeycomb electronic ignition head 31 on the control device 3, and the loading is completed at this time. The target distance is measured by the laser rangefinder 1, and the target distance information is transmitted to the control device 3. According to the target distance information, the microelectronic chip 32 inside the control device 3 solves the internal and external ballistics to obtain the number of firing holes that need to be ignited, and performs ignition setting. After setting is completed, the part to be ignited on the honeycomb electronic ignition head 31 is in a pass state, and the part that does not need to be ignited is in a break state. When the operator implements the firing action, the microelectronic chip 32 issues an ignition command, and the honeycomb electronic ignition head 31 ignites the propellant in the corresponding firing hole to complete the firing action. Driven by the gunpowder gas obtained by burning a specific amount of propellant, the bullet 23 is ejected from the chamber to complete a non-lethal killing attack. After the shooting is completed, the barrel is rotated to expose the porous cartridge case 21, and the cartridge case is withdrawn for recovery. At this point, the entire round of work is completed and the next special charge projectile 2 can be loaded to continue shooting.

[0041] Example 2

[0042] like Figure 4 As shown, the firing holes of the porous cartridge case 21 are arranged in a ring shape, and the electronic ignition heads on the control device 3 are arranged in a ring shape.

[0043] Example 3

[0044] like Figure 5 As shown, the firing holes of the porous cartridge case 21 are arranged in a fan shape, and the electronic ignition head on the control device 3 is arranged in a fan shape.

[0045] Example 4

[0046] like Figure 6 As shown, the firing holes of the porous cartridge case 21 are arranged in a rectangular shape, and the electronic ignition head on the control device 3 is arranged in a rectangular shape.

[0047] The present invention controls the projectile exit velocity by adjusting the weight of the ignited propellant charge, and the implementation path is to ignite multiple separate propellant charges by electronic control. The honeycomb propellant charge and electronic ignition head shown in Example 1 are preferred embodiments of the present invention, and can be designed into other forms as needed, such as annular hole groups (Example 2), fan-shaped hole groups (Example 3), rectangular hole groups (Example 4) and other forms of multi-hole launch methods. All those that meet the above core ideas and implementation paths should belong to the scope of the present invention.
