Background

At present, live ammunition target shooting cannot be widely applied to civil entertainment and shooting confrontation activities because of the problem that kinetic energy of bullets exceeds the standard and violates relevant national legal provisions. The traditional infrared laser simulated shooting technology cannot carry out accurate aiming shooting because the emitted light is invisible and the infrared reflection interference is serious. At present, the shooting and shooting simulation target shooting technology based on visible light emission is generally judged by light intensity judgment and reception or image recognition under the condition of not using codes, and is easily seriously influenced by ambient light; in the case of using codes, the duration of each simulated firing "shot" will be longer, and due to the presence of shot jitter, continuous light will be formed at the beginning of the target, so that an accurate shooting simulation with only one impact point when the bullet hits the target cannot be achieved. Meanwhile, in various shooting competitions, the requirements of the size and the shape of a target are different, and the existing simulation shooting system is very inconvenient to apply and needs to be specially customized.

When an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The visible light shooting target hitting device provided by the invention uses mechanical alignment to accurately aim shooting targets, and can be widely applied to shooting training, game entertainment or professional shooting scoring games. Referring to both fig. 1 and 4, a visible light projectile shooting practice device generally includes a firing unit 100 and a receiving target unit 200.

The firing unit 100 is typically a firearm that includes a housing 110, a front isocenter 120, and a rear isocenter 130 that is aimed for firing when the eyes, front isocenter 120, rear isocenter 130, and target (i.e., the target location that receives the target unit 200) are in the same line.

In the present invention, as shown in fig. 1, the firing unit 100 further includes a light emitter 140. The light emitter 140 is disposed at an exit end of the housing 110, and the light emitter 140 emits a visible light bullet, which is emitted from the exit end of the housing 110, similar to a live-bullet firing mode. The light emitter 140 includes, but is not limited to, using a visible laser emitter.

Further, housing 110 includes a barrel 111, barrel 111 being located at an outlet end of housing 110, a firing end of barrel 111 being disposed in alignment with the outlet end of housing 110. The emitting end of the barrel 111 is provided with the light emitter 140 as described above, and the barrel 111 is generally cylindrical in shape. The light emitter 140 is also configured as a cylinder, and is disposed within the barrel 111 to match the shape of the barrel 111 to better control the emitting position of the light emitter 140. The front end of the light emitter 140 is aligned with the discharge end of the barrel 111, and the rear end of the light emitter 140 is connected to the connection end of the barrel 111 by a fixing ring 150. The light is emitted from the connecting end to the emitting end of the barrel 111. Retainer ring 150 includes, but is not limited to, a retainer ring made of rubber or other resilient material. Specifically, the inner diameter of the fixing ring 150 is equal to the outer diameter of the light emitter 140; the outer diameter of the retainer ring 150 is equal to the inner diameter of the barrel 111, that is, the inner diameter of the barrel 111 catches the outer diameter of the retainer ring 150, and the inner diameter of the retainer ring 150 catches the light emitter 140.

Referring to fig. 1 and 2 together, fig. 2 is a schematic cross-sectional view of the barrel 111 and the light emitter 140 of the visible light bullet shooting practice apparatus of fig. 1 taken along the sectional line II-II. An elastic sheet 160 is disposed between the front end of the light emitter 140 and the emitting end of the barrel 111; one end of the elastic piece 160 is fixed to the emitting end of the barrel 111, and the other end abuts against the light emitter 140. The elastic piece 160 supports the light emitter 140 toward the inner side wall of the barrel 111. Specifically, the elastic sheet 160 may employ, but is not limited to, elastic plastic and metal foil.

At least two positioning members 170 are disposed on the barrel 111, and the positioning members 170 are disposed on the barrel 111 and adjacent to the discharge end of the barrel 111. The positioning members 170 are distributed on the same circumferential line on the barrel 111. The number of the positioning members 170 is preferably two or three. The positioning member 170 is fixed to the light emitter 140, and cooperates with the elastic sheet 160 to fix the light emitter 140. The positioning member 170 includes a positioning hole 171 and a positioning post 172; the positioning hole 171 is opened on the barrel 111, and the positioning post 172 passes through the positioning hole 171 and abuts against and is fixed with the light emitter 140. If two positioning members 170 are used, the center lines of the two positioning holes 171 are vertically arranged, and the two positioning holes 171 are symmetrically arranged with the position of the elastic piece 160 as the center; if three positioning members 170 are used, the positioning holes 171 are located in the upper half circumference of the barrel 111, any two positioning holes 171 are located at an interval of about 60 ° in the upper half circumference direction of the barrel 111, and the elastic piece 160 is disposed in the lower half circumference of the barrel 111. Wherein the barrel 111 is divided into an upper half circumference and a lower half circumference according to a diameter perpendicular to a diameter through which the elastic sheet 160 is located. Specifically, the positioning posts 172 can be, but are not limited to, screws.

Because the rear end of the light emitter 140 of the cylinder is fixed by the fixing ring 150, but the fixing ring 150 can generate a certain deformation under a certain external force, that is, the rear end of the light emitter 140 keeps the position unchanged while the direction of the whole cylinder can be changed, as shown in fig. 1, after the rear end of the light emitter 140 is fixed, under the combined action of the elastic force of the elastic sheet 160, the position of the front end of the light emitter 140 in the gun barrel can be adjusted by 360 degrees by adjusting the spiral depth of the positioning column 172, thereby realizing the adjustment of the emission direction of the visible light bomb.

The housing 110 further includes a grip 112 and a trigger 113. The grip portion 112 is disposed substantially perpendicular to the barrel 111. The grip 112 is configured to be held by the palm of the user's hand when the shooting unit 100 is used, to achieve a grip of the shooting unit 100. The trigger 113 is disposed adjacent to the grip portion 112 and on a side of the grip portion 112 adjacent to the barrel 111. The trigger 113 may generate a trigger signal upon operation by a user. In at least one embodiment of the present invention, the user generates the trigger signal by performing a hooking operation on the trigger 113.

Referring to fig. 3, fig. 3 is a block diagram of a first processor 180 according to an embodiment of the invention. The light emitter 140 is further provided therein with a first processor 180 and a memory 300, and the first processor 180 includes a light source driving module 181, a switching element SW, and a first processing module 183. The memory 300 has stored therein a plurality of program modules that are executed by the first processor 180 and perform the steps of:

step S510, receiving a trigger signal.

The first processing module 183 has a first pin P1. In at least one embodiment of the present invention, the first pin P1 is a General Purpose Input Output (GPIO) pin. The first pin P1 of the first processing module 183 receives the trigger signal of the trigger 113.

Step S520, converting the trigger signal into a laser emission signal.

The second pin P2 of the first processing module 183 is electrically connected to the control terminal of the switching element SW. The second pin P2 of the first processing module 183 outputs a laser emission signal to control the switching element SW to be turned on and off. The laser emission signal may be a signal that varies at a predetermined cycle. In at least one embodiment of the present invention, the laser emission signal may be a square wave signal. In other embodiments, the laser emission signal may be a sinusoidal signal or other periodically varying signal.

In step S530, the laser emission signal controls the light emitter 140 to emit the visible light bullet.

The light source driving module 181 is electrically connected to the light emitter 140, and is configured to provide a driving current to the light emitter 140. In at least one embodiment of the present invention, the light source driving module 181 is a dc driving circuit. The anode of the light emitter 140 is electrically connected to the light source driving module 181, and the cathode of the light emitter 140 is grounded through the switch element SW. In at least one embodiment of the present invention, the switching element SW is a P-type field effect transistor (MOSFET). When the switch element SW is turned on, the light emitter 140 emits visible light according to the driving current of the light source driving module 181. The switching element SW is controlled to be periodically turned on according to the laser emission signal, so that the visible light ray emitted from the light emitter 140 flickers at a predetermined frequency. At a predetermined frequency, the flicker of the light emitter 140 cannot be sensed by human eyes, and the light emitter 140 emits a visible light bullet. The period of the laser emission signal is associated with a preset frequency. In at least one embodiment of the present invention, the period of the laser emission signal may be equal to the corresponding preset frequency of the light emitter 140. Specifically, when the laser emission signal is at a low level, the switching element SW turns on the light emitter 140 to emit the visible light bullet with a preset frequency according to the driving current of the light source driving module 181. When the laser emission signal is at a high level, the switching element SW is turned off, and the light emitter 140 does not emit the visible ray bullet. The first processing module 183 of the first processor 180 controls the light emitter 140 to emit a "shot" of visible light including a predetermined frequency. The preset frequency of the visible light bomb is 1 KHz-1 MKz.

In some preferred embodiments, the first processor 180 includes a feedback module 184. A plurality of program modules are run by the first processor 180 and further perform the steps of:

and step S540, simulating the recoil strength generated in the visible light bomb launching process.

The feedback module 184 is electrically connected to the third pin P3 of the first processing module 183. When the trigger 113 generates the trigger signal, the first processing module 183 controls the feedback module 184 to simulate the recoil strength generated during the firing of the visible light bomb. In at least one embodiment of the present invention, the feedback module 184 may use an eccentric rotor motor, or a more powerful transverse linear motor, to achieve better simulation.

In other preferred embodiments, the first processor 180 includes an audio module 185. A plurality of program modules are run by the first processor 180 and further perform the steps of:

in step S550, the sound intensity generated in the process of launching the visible light bomb is simulated.

The audio module 185 is electrically connected to the fourth pin P4 of the first processing module 183. When the trigger 113 generates the trigger signal, the first processing module 183 controls the audio module 185 to simulate the intensity of the sound generated during the firing of the visible light bomb. In at least one embodiment of the present invention, a variety of different sound effects may be stored within the audio module 185. A variety of different sound effects are used to simulate the sound corresponding to different bullet shots or explosions. While the light emitter 140 emits the visible light bullet, the audio module 185 simulates the sound of a shot or explosion of a different bullet, simulating the vibration sound at the time of firing. The sense of the participator in the shooting fight is more real.

The invention also provides a receiving target unit 200. fig. 4 is a schematic front view of the receiving target unit 200 in a visible light bullet shooting practice apparatus according to one embodiment of the invention. As shown in fig. 4, the receiving target unit 200 includes a plurality of receiving targets 210 that are spliceable. Seamless planar mosaic splicing can be achieved by two connected receiving targets 210, and a single receiving target 210 is a regular polygon and can be but is not limited to a triangle, a quadrangle, a pentagon and a hexagon. In the present invention, a hexagonal receiving target 210 is preferably used.

The target body of each receiving target 210 is a light transmissive material, and the edge and bottom portions thereof are opaque materials. The light-transmitting material can be made of light-transmitting materials such as plastic with a light-diffusing function or a frosted acrylic material. A photo sensor S (shown in fig. 6) is attached to the target body of each receiving target 210, and receives the visible light bullet emitted from the light emitter 140. When the visible light bullet is emitted to the front surface of the receiving target 210, it can penetrate and fall onto the photosensor S that receives the signal. The edge portion and the bottom portion of the receiving target 210 are both made of opaque materials, so that misjudgment caused by the fact that visible light bombs are incident on the adjacent receiving target 210 through the edge and the bottom portion of the receiving target 210 is avoided.

Specifically, as shown in fig. 5, fig. 5 is a partially exploded rear view of the receiving target unit 200 shown in fig. 4. The two receiving targets 210 are connected to each other by a connector 220. Each connecting side of the connector 220 is provided with a connecting clip 221, which is fixedly connected with a clip groove 211 formed on the receiving target 210, and the clip groove 211 is located on the side of the non-light-receiving surface of the receiving target 210.

The conversion module 231 receives the visible light projectile emitted from the light emitter 140 in the shooting unit 100 and converts the visible light projectile into a first electrical signal. Wherein the visible light bullet is incident on the target body on the receiving target 210. The conversion module 231 includes a voltage source DC, a first voltage dividing resistor R1, a plurality of photo sensors S (only one is illustrated in fig. 6), and a second voltage dividing resistor R2. One end of the first voltage dividing resistor R1 is electrically connected to the voltage source DC, and the other end is electrically connected to the first end of the photo sensor S. One end of the second voltage-dividing resistor R2 is electrically connected to the second end of the photosensor S, and the other end is grounded. A plurality of the photo sensors S are connected in parallel. The photosensitive sensor S may be, but is not limited to, a photodiode or a silicon photo cell. The photosensitive sensor S works in a reverse bias state, when visible light, such as visible light bomb, enters the photosensitive sensor S, the positive electrode of the photosensitive sensor S can generate voltage which changes along with the change of light intensity, and photoelectric conversion is achieved.

Step S630, the electrical signal is processed to obtain a valid signal.

One end of the first capacitor C1 is electrically connected to the anode of the photosensor S, and the other end is electrically connected to the band-pass filtering and amplifying module 232. The voltage generated by the photosensitive sensor S is isolated through the first capacitor C1, and the second electric signal is obtained after the direct-current component is filtered and removed, so that part of background light which is not rapidly converted can be effectively removed. The band-pass filtering and amplifying module 232 amplifies the second electrical signal and filters the electrical signal of the second electrical signal lower than the preset frequency and higher than the preset frequency to obtain a third electrical signal. The specific frequency detecting module 233 detects a plurality of specific frequencies in the third electrical signal, and generates at least one effective signal to the second processing module 234 when at least one specific frequency is detected. The band-pass filtering and amplifying module 232 can filter most of the interference signals emitted by the illumination light source.

In step S640, the status information of the valid signal hitting the receiving target 210 is displayed.

The first display module 235 displays status information of the valid signal hitting the receiving target 210, and the first display module 235 may be, but is not limited to, using an LED indicator light. Specifically, after receiving the target 210 during visible light emission, the LED indicator lights up.

Each of the receive targets 210 has identical circuitry and is provided with a second processor 230, and each of the receive targets 210 is connected by a connector 220.
