[0001] This utility model relates to the field of military, counter-terrorism and explosion-proof training technology, and in particular to an acoustic and light simulation training grenade. Background Technology

[0002] In military training, security drills, and civilian applications, grenade throwing is a fundamental and crucial skill training subject. However, training with live ammunition or high-explosive training rounds presents significant safety hazards and high costs. Live ammunition is extremely destructive; operational errors can cause serious personal injury and property damage. Furthermore, live ammunition is disposable and cannot be reused, resulting in extremely high training costs. To overcome these shortcomings, various training grenades have emerged as alternatives to live ammunition. Currently, three common types of training grenades exist: the first type has all components made of inert materials and lacks audible and visual indicators; the second type has audible and visual simulation but is for single use only; and the third type has audible and visual simulation and can be reused, but replacing the audible and visual components is cumbersome, requiring specialized wrenches for assembly and disassembly, leading to low efficiency. Therefore, none of these three types of training grenades can replace live ammunition for training and cannot complete technical and tactical drills. To address this deficiency, an audible and visual simulation training grenade is proposed. Summary of the Invention

Figures 1 to 5As shown, the present invention provides an audio-visual simulation training grenade, comprising: a projectile 9, the projectile 9 being made of polyamide 6 and having an overall elliptical shape to simulate the shape of a grenade; a grip structure connected to the top of the projectile 9; a sensor 3 provided at the top of the projectile 9; the sensor 3 being connected to a chip 7 via a wire; the chip 7 being connected to a battery 8; the battery 8 continuously supplying power to the chip 7; the chip 7 being connected to a socket 10 via a wire; a round hole at the bottom of the projectile 9; the socket 10 being installed in the round hole at the bottom of the projectile 9; and the socket 10 being connected to an electronic explosive head.

[0019] The specific structure of this utility model will be further described below.

[0020] The bottom of the projectile 9 can be connected to the projectile base 11. At this time, the round hole is opened on the projectile base 11, the socket 10 is located above the round hole, the inner wall of the lower part of the round hole is provided with threads, and the thread is connected to the fixing sleeve 12. The socket 10 is located above the fixing sleeve 12 and is limited by the fixing sleeve 12. At the same time, the fixing sleeve 12 is used to limit the electronic explosive head. The projectile 9 has a shockproof function.

[0021] The grip structure includes a grip 4, with a top plate at its top. The sidewall of the grip 4 is arc-shaped to match the sidewall of the projectile 9. One end of the top plate of the grip 4 is connected to the top of the projectile 9 via a pin 1, allowing the grip 4 to rotate along the pin 1. The sidewall of the grip 4 is connected to the projectile 9 via a safety pin 6. A pull ring is provided on the safety pin 6; removing the pull ring allows the grip 4 to be separated from the projectile 9. When connected, the safety pin 6 passes through a safety pin hole 17 on the projectile 9. One side of the safety pin hole 17 is a round hole, and the other side is a flared opening. The flared opening guides the safety pin 6 for quick installation. A magnet 2 is located below the top plate of the grip 4, and the position of the magnet 2 corresponds to that of the sensor 3. The magnet 2 triggers the sensor 3 through a magnetic field. A spring sheet 5 is welded to the side wall of the grip 4 corresponding to the side of the projectile 9. When the safety pin 6 is inserted into the safety pin hole 17 of the projectile 9, it compresses the spring sheet 5 downward. After the safety pin 6 is pulled out, the spring sheet 5 loses the compression of the safety pin 6, and the grip will spring off the projectile 9 and rotate around the pin 1, thereby causing the magnet 2 to leave the sensor 3.

[0022] The electronic explosion head includes an ignition head 13, which simulates the sound and light of an explosion. The ignition head 13 has dimensions of ø8×30mm. The top of the ignition head 13 is connected to the positive and negative terminals of a plug 14 via two wires. The ignition head 13 and plug 14 are welded at their edges, and silicone rubber is applied to the weld to prevent wear. The wires between the ignition head 13 and plug 14 are sealed with sealant 15 to seal the space around the wires and prevent interference with the connection. A tubing 16 is fitted over the ignition head 13. The outer wall of the tubing 16 is coated with silicone rubber to fix the tubing and prevent movement. The tubing 16 protects the ignition head 13 from damage. In use, the electronic explosive head is connected to the socket 10 via the plug 14. The electronic explosive head can be installed or removed from the socket 10 and replaced at any time. The electronic explosive head has a conical structure. After being inserted into the round hole of the bullet base 11, the electronic explosive head serves to prevent water and dust.

[0023] When the grenade of this utility model is used, when the safety pin 6 is pulled out, the grip 4 is springed open by the elastic force of the spring plate 5, so that the magnet 2 below the top plate of the grip 4 is separated from the sensor 3 at the top of the grenade body 9. The sensor 3 sends a signal to the chip 7, and the chip 7 will output the rated voltage and current to the load after 3 seconds, detonating the ignition head 13 in the electronic explosive head and producing an explosion sound and light. After the training grenade explodes, the electronic explosive head is pulled out and replaced for the next training.

[0024] The sound and light simulated grenade box also includes a grenade box, which is equipped with several charging plugs. These charging plugs cooperate with a socket 10, which simultaneously functions as a load and a charging circuit, automatically switching between charging and discharging. The battery 7 can be charged via the charging plugs. The charging plugs use a DC 3.5×1.35 plug and are connected to an external 220V power cord for power supply. The grenade box can have multiple plugs to charge multiple grenades simultaneously. In this embodiment, 40 charging plugs compatible with the socket 9 of the grenade body are provided, allowing for charging of one grenade at a time, or charging of multiple grenades simultaneously as needed.

[0025] In practice, the operator grips the grenade handle 4 and the grenade body 9 with their right hand, inserts the electronic detonator into the round hole 11 at the base of the grenade, and holds the pull ring on the safety pin 6 with their left index finger and thumb. Rotating the pull ring disengages the pin on the safety pin 6, and pulling the pull ring removes the safety pin 6, at which point the grenade is ready to fire. The grenade is then forcefully thrown at the target. The spring plate 5 near the outer wall of the grenade body 9 loses the compression of the safety pin 6 and pops outward, causing the handle 4 to rotate around the pin 1. The magnet 2 below the top plate of the handle 4 separates from the sensor 3 at the top of the grenade body 9. The sensor 3 detects the change in magnetic field and sends a signal to the chip 7. After being powered on for 3 seconds, the chip 7 outputs its rated voltage and current to the load, detonating the ignition head 13 in the electronic detonator, producing a simulated explosion sound of 160 decibels. After the training grenade explodes, remove the old electronic detonator, rotate the grip 4 back to its original position, insert the safety pin 6 into the safety pin hole, and install the new electronic detonator into the round hole 11 at the base of the grenade. The grenade can then be thrown again. When the training grenade body 9 is low on power, remove the training grenade box, insert the grenade into the plug inside the box, and charge the battery 7 inside the grenade body 9. After charging, the grenade's lifespan can reach over 2000 uses.

[0026] This utility model provides a sound and light simulation training grenade. The device has a simple structure, including a projectile 9 made of high-strength polyamide 6, injection molded in one piece. A grip structure is connected to the top of the projectile 9. A sensor 3 is located at the top of the projectile's interior. A circular hole is provided in the base 11. The sensor 3 is connected to a chip 7 via a wire. The chip 7 is connected to a battery 8, which powers the chip 7. The chip 7 is connected to a socket 10 via a wire. The socket 10 is installed at the top of the circular hole in the base 11 and is connected to an electronic detonator. After the operator pulls out the ring on the safety pin 6, the training grenade is thrown towards the target. After the grenade is released, the grip 4 springs open under the action of the side wall spring 5, separating the magnet 2 on the grip 4 from the sensor 3 inside the projectile 9. The sensor 3 sends a signal to the chip 7, which outputs a rated voltage and current to the load after a 3-second delay, igniting the detonator 13. The detonator, after being processed by a special process, produces a simulated explosion sound of approximately 160 decibels. The training grenade adopts a split structure, and the grenade body and its internal acoustic and optical components are reusable. Each use only requires replacing the electronic explosive head and assembling the safety pin. It is also equipped with a grenade box, and the training grenade body can be recharged at any time when it is depleted, thereby improving its service life and achieving the goal of multiple reuses. This training grenade operates in the same way as a live grenade, is easy to operate and carry, thereby improving training efficiency and facilitating the completion of tactical coordination training.
