A shot counter and a cartridge collector

Abstract

The application discloses a shooting counter and a bullet collector, and belongs to the technical field of gun detection. The shooting counter is arranged at the entrance of the bullet collector, and comprises an infrared laser head arranged at one corner of the entrance and a light receiving plate located in the light coverage range of the infrared laser head. Photoelectric sensors are linearly arranged on one side of the light receiving plate facing the infrared laser head. The light emitted by the infrared laser head is aimed at the photoelectric sensors on the light receiving plate, and a detection surface area is formed at the entrance of the bullet collector. When the bullet head is shot into the bullet collector and passes through the detection surface area, the light sensed by the photoelectric sensors changes, thereby causing the level to change. The light receiving plate acquires the level change, and the shooting counter is increased by one, thereby realizing shooting counting. The application forms an intelligent, closed and traceable intelligent shooting system as a whole based on the consumable replacement reminder of the shooting counter, the bullet taking reminder and the single continuous shooting counting automatic zero clearing mechanism.

Description

Technical Field

[0001] This invention belongs to the field of firearm detection technology, specifically relating to a shooting counter and a bullet collector. Background Technology

[0002] Before firearms are documented, various tests are required, including ballistic performance testing. A bullet catcher is used in the ballistic testing phase to collect bullets, preserving rifling marks for later comparison. In practical applications, bullet catchers mostly achieve bullet stopping by combining multiple layers of elastic materials (such as silicone sheets) with a metal backplate, resulting in a compact structure suitable for indoor environments. In existing technologies, bullet-stopping sheets are mostly made of silicone sheets with a hardness (Shore A) of 40-60 and a thickness of 5-20mm. To facilitate the replacement of these consumable sheets, existing technologies use a clamping frame structure for detachable clamping and fixation. For example, the invention patent CN109443103B, authorized on August 15, 2023, uses a fixing clamp to detachably fix the bullet stop plate, which also facilitates the fixation of the bullet stop plate.

[0003] Bullet catchers are consumables, but existing bullet catchers lack a bullet detection mechanism, making it impossible to track the number of consecutive shots and the total number of shots. Therefore, there is no basis for replacing the consumables, and staff cannot accurately determine when replacement is needed. Furthermore, bullet catchers are typically used in conjunction with front-end velocity measuring equipment, and the firing distance is relatively long, which may result in bullets deviating from the catcher. However, existing bullet catchers lack a mechanism to detect whether a bullet has entered the catcher. When the number of bullets collected from the catcher does not match the number of shots, it is impossible to visually determine whether the bullet has deviated from the equipment or remains inside the catcher, hindering bullet retrieval. Summary of the Invention

[0004] To address the problem that existing bullet collectors lack a bullet detection mechanism, this invention proposes a firing counter and a bullet collector.

[0005] This invention protects a shooting counter, which is set at the entrance of a bullet collector, including an infrared laser head set at one corner of the entrance, and a light receiving plate located within the light coverage area of ​​the infrared laser head. The side of the light receiving plate facing the infrared laser head is linearly equipped with photoelectric sensors for sensing the light emitted by the infrared laser head.

[0006] The light emitted by the infrared laser head is aligned with the photoelectric sensor on the light receiving board, forming a detection area at the bullet collector inlet. When the bullet enters the bullet collector and passes through this detection area, the light sensed by the photoelectric sensor changes, causing a change in voltage level. The light receiving board acquires this voltage level change, and the firing counter increments by 1, thus realizing firing count.

[0007] As a preferred option, a laser head fixing position with a 45-degree inclination is set at one corner of the bullet collector inlet, and the light receiving plate is set in an L-shape diagonally opposite it.

[0008] As a preferred option, the optical receiver board is composed of multiple circuit boards spliced ​​together and fixed at the inlet of the collector by a circuit board bracket.

[0009] This invention also protects a bullet collector, which has the aforementioned firing counter installed at the entrance. The counting objects include the number of consecutive shots in a single burst and the total number of consumables fired at present. When the total number of consumables fired at present reaches a preset threshold, the system reminds the staff to replace the consumables.

[0010] As a preferred option, a decorative plate is provided at the inlet of the ammunition collector. The decorative plate has a first light-transmitting port corresponding to the position where the infrared laser head emits light, and a second light-transmitting port corresponding to the position of the photoelectric sensor.

[0011] As a preferred option, the ammunition collector is equipped with an ammunition drawer. The bullets entering the ammunition collector are collected into the ammunition drawer. The ammunition drawer is equipped with a sensor switch. The operation of opening the drawer to retrieve the bullets, in conjunction with the next firing start signal, realizes the automatic zeroing of the number of bullets fired in a single continuous firing.

[0012] As a preferred option, a display screen is installed next to the ammunition drawer, which displays the number of shots fired in a single continuous burst and the total number of consumables fired so far.

[0013] The beneficial effects of this invention are:

[0014] 1. An infrared detection-based firing counter is installed at the ammunition collector inlet to provide near-complete coverage of the inlet, enabling accurate counting of the number of incoming projectiles. In conjunction with the intelligent firing system, a firing threshold corresponding to consumable replacement is set to provide timely reminders for consumable replacement.

[0015] 2. The ammunition drawer uses light to remind the user to retrieve ammunition. Its sensor switch signal works in conjunction with the next firing start signal to automatically reset the number of consecutive shots in a single firing cycle.

[0016] 3. Based on the consumable replacement reminders, ammunition retrieval reminders, and automatic zeroing mechanism for single continuous firing counts, an intelligent, closed, and traceable intelligent shooting system is formed as a whole. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0026] Example 1

[0027] A firing counter, such as Figure 1-5 As shown, an infrared laser head 2 is positioned at one corner of the inlet 1 of the ammunition collector, and a light receiving plate 3 is located within the light coverage area of ​​the infrared laser head. A photoelectric sensor 301 is linearly arranged on the side of the light receiving plate 3 facing the infrared laser head to sense the light emitted by the infrared laser head and convert it into an electrical signal. The most common photoelectric sensor is an infrared photodiode.

[0028] See Figure 5 The photoelectric sensors 301 are arranged linearly, one next to the other, on the light receiving plate 3. The light emitted by the infrared laser head 2 is aligned with the photoelectric sensors 301 on the light receiving plate 3, forming a detection area at the inlet of the projectile collector. (See [reference]) Figure 6 When the projectile enters the projectile collector and passes through the detection area, the light detected by the photoelectric sensor 301 changes, causing a change in the electrical level. The light receiving plate 3 acquires this change in level, and the firing counter increments by 1, thereby realizing the firing count.

[0029] To ensure that the infrared laser head 2 covers the maximum entrance area, a laser head fixing position 4 at a 45-degree angle is set at one corner of the bomb collector entrance (see...). Figure 3 The optical receiver 3 is arranged in an L-shape with its diagonal (see...). Figure 5 ).

[0030] Considering that excessively long circuit boards are inconvenient to manufacture and maintain, leading to increased costs, in this embodiment, the optical receiver board 3 is composed of multiple circuit boards spliced ​​together (see...). Figure 5 Meanwhile, to ensure the stability of the circuit board installation, multiple circuit boards are fixed to the inlet 1 of the bomb collector by the circuit board bracket 5.

[0031] Example 2

[0032] A type of ammunition collector, such as Figure 1 As shown, a shooting counter disclosed in Embodiment 1 is installed at the entrance. The counting objects include the number of consecutive shots and the current total number of consumables shot (which can be achieved based on simple control logic). When the current total number of consumables shot reaches a preset threshold, the staff is reminded to replace the consumables.

[0033] The number of bullets fired in a single burst is compared with the actual number of bullets collected from the bullet collector to determine whether any bullets have deviated from the equipment, thus clarifying the search direction for "lost" bullets.

[0034] When the total number of consumables fired reaches a preset threshold, the system alerts staff to replace the consumables, ensuring good ballistic protection while maximizing the utilization of consumables (ballistic rings / sheets). After replacement, the total number of consumables fired is reset to zero. It's worth noting that the "preset threshold" in this system can be adjusted by administrators to determine the optimal threshold based on actual design feedback.

[0035] For aesthetic reasons, a decorative panel 6 is provided at the inlet 1 of the ammunition collector. A first light-transmitting opening 601 is provided on the decorative panel corresponding to the light-emitting position of the infrared laser head 2, and a second light-transmitting opening 602 is provided corresponding to the position of the photoelectric sensor 301. Figure 7 As shown.

[0036] The ammunition collector is equipped with an ammunition drawer 7. The projectiles entering the collector are collected into the ammunition drawer 7 via a projectile conveyor belt 8. (See also...) Figure 8 To facilitate user operation and avoid forgetting to reset the ammunition count before firing, the ammunition drawer is equipped with a sensor switch. Opening the drawer to retrieve ammunition, in conjunction with the signal to initiate the next firing cycle, automatically resets the ammunition count for each consecutive shot.

[0037] Meanwhile, a light-up panel can be installed on the bullet retrieval drawer panel. After the bullets are collected by the bullet conveyor belt, the light will illuminate to prompt the user to open the bullet retrieval drawer to retrieve the bullets.

[0038] To visually display the count, a display screen 9 is installed next to the retrieval drawer 7. (See also...) Figure 1 , Figure 8Display screen 9 shows the number of shots fired in a single burst and the total number of consumables fired. Display screen 9 can be a touchscreen, equipped with a shooting record query function.

[0039] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
