Description

Technical Field

[0001] The invention relates to the field of simulated guns, in particular to a simulated gun with accurate recoil feedback. Background Art

[0002] Gun shooting is one of the core skills of the police, soldiers, etc. In order to conduct shooting training for relevant personnel, the existing technology can simulate shooting training through images, by projecting the corresponding shooting points. When the trainee shoots, the training laser can project the corresponding laser point in the projection, so that the image simulation shooting system can recognize the trainee's shooting position.

[0003] During the shooting process of the gun, the explosive in the cartridge case burns to push the bullet out, and the cartridge case hits the slide sleeve to move the slide sleeve backward. After the slide sleeve moves backward, the cartridge case pops out from the slide sleeve, and the rear end of the chamber will tilt slightly downward to connect for loading the next bullet. This process will produce recoil to drive the trainee's arm to rotate and jump up. In the prior art, in order to simulate the recoil of the gun, a propulsion structure is generally set in the gun, and the propulsion structure is horizontally pushed backward after the trigger is triggered, so as to horizontally hit the slide sleeve to simulate the recoil, such as the prior art of the publication number CN216523396U, which is named as a laser transmitter recoil generating device. However, the force direction and occurrence time of the recoil generated during the firing process of the gun are very complicated, and the prior art is difficult to provide a recoil close to the real shooting during the training process.

[0004] The purpose of the present invention is to design a simulated gun with accurate feedback of recoil force in view of the above-mentioned problems in the prior art. Summary of the invention

[0005] In view of the problems existing in the above-mentioned prior art, the present invention provides a simulated gun with accurate feedback of recoil, which can effectively solve at least one problem existing in the above-mentioned prior art.

[0006] The technical solution of the present invention is:

[0007] A simulated firearm with accurate recoil feedback, comprising:

[0008] Gun body;

[0009] A slide, slidably disposed on the gun body;

[0010] An electromagnetic coil mounting seat is fixedly arranged at the top end of the gun body and accommodated in the sliding sleeve. The interior of the electromagnetic coil mounting seat is a hollow structure. The rear section bottom surface of the inner ring of the electromagnetic coil mounting seat is provided with a slope, and the slope of the slope gradually decreases toward the rear end direction of the electromagnetic coil mounting seat. The inner ring of the electromagnetic coil mounting seat is provided with a groove body at the rear end of the slope.

[0011] An electromagnetic coil, wound around the outer ring of the electromagnetic coil mounting seat;

[0012] A magnetic rod can be slidably mounted on the inner ring of the electromagnetic coil mounting seat, the magnetic rod is fixedly connected to the sliding sleeve, an elastic telescopic rod is arranged at the front end of the magnetic rod corresponding to the slope, the elastic telescopic rod is connected to a sliding wheel, when the magnetic rod drives the sliding wheel to move backward along the slope, the elastic telescopic rod is compressed, and when the magnetic rod drives the sliding wheel to move to the slot body, the compression of the elastic telescopic rod is released.

[0013] Furthermore, the slope has a gradient of 3-5°.

[0014] Furthermore, the depth of the groove body is greater than the deepest point of the slope.

[0015] Furthermore, a first elastic member is provided at the front section of the gun body, a rear end of the first elastic member is connected to the gun body, a front section of the first elastic member is connected to the front end of the slide, and the first elastic member is used to provide a rebound force to move the slide forward after the slide moves backward.

[0016] Furthermore, the top end of the elastic telescopic rod is hinged to the magnetic rod, and a second elastic member is arranged between the elastic telescopic rod and the magnetic rod. When the sliding sleeve rebounds, the elastic telescopic rod swings backward to make the sliding wheel return to the slope, and the second elastic member is used to provide a rebound force to the elastic telescopic rod to make the elastic telescopic rod return to the vertical downward direction.

[0017] Furthermore, the magnetic rod is provided with a placement cavity, the opening of the placement cavity faces downward, the front end surface of the placement cavity is perpendicular to the length direction of the magnetic rod, the elastic telescopic rod is arranged on one side of the front end surface of the placement cavity, and the front end surface of the placement cavity limits the maximum swing angle of the elastic telescopic rod.

[0018] Furthermore, it comprises an energy storage battery, the shell of the energy storage battery is shaped like a magazine, and the energy storage battery is used to supply power to the electromagnetic coil.

[0019] Furthermore, it includes a trigger button, which is arranged on the gun body. After the trigger of the gun body is pressed, the trigger presses the trigger button.

[0020] Furthermore, the elastic telescopic rod comprises a telescopic rod, and a third elastic member is sleeved on the outer periphery of the telescopic rod.

[0021] Therefore, the present invention provides the following effects and / or advantages:

[0022] The simulated gun provided by the present application can provide a sufficient amount of lateral recoil component and a small amount of longitudinal recoil component during the backward movement of the magnetic rod, simulate the actual recoil of the gun, and provide the feeling of the shell flying out of the slide, giving the trainee a close to real gun recoil simulation feeling.

[0023] The present application uses a magnetic rod to drive the slide to slide backward to simulate the lateral component of the recoil force when the gun is fired, and uses the downward force exerted on the slope by the elastic telescopic rod when it is compressed to simulate the longitudinal component of the recoil force when the gun is fired. The compression amount is then instantly released when the elastic telescopic rod falls into the groove to simulate the feeling of the bullet shell leaving the opening of the slide, thereby giving the trainee the feeling of a series of actions in the process of firing the gun.

[0024] The present application provides a structure in which the elastic telescopic rod can swing and is connected by a third elastic member, so as to provide an evasive action of the elastic telescopic rod during the process of resetting the magnetic rod forward, thereby preventing the elastic telescopic rod from hindering the forward movement of the magnetic rod.

The purpose and other advantages of the present invention are realized and obtained by the structures particularly pointed out in the description and the drawings.

[0035] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the embodiments in conjunction with the accompanying drawings:

[0036] refer to Figure 1-8 , a simulated firearm with precise recoil feedback, including:

[0037] Gun body 1;

[0038] A slide 2 is slidably disposed on the gun body 1;

[0039] In this embodiment, the gun body 1 and the slide 2 are structures with corresponding shapes and weights prepared according to the shape of the gun, and the gun body 1 can be provided with a laser emitter, etc., for emitting an infrared light spot that is captured by the corresponding electronic target to obtain the shooting position.

[0040] The electromagnetic coil mounting seat 3 is fixedly arranged at the top end of the gun body 1 and accommodated in the slide 2. The interior of the electromagnetic coil mounting seat 3 is a hollow structure. The rear bottom surface of the inner ring of the electromagnetic coil mounting seat 3 is provided with a slope 301. The slope of the slope 301 gradually decreases toward the rear end of the electromagnetic coil mounting seat 3. The inner ring of the electromagnetic coil mounting seat 3 is provided with a groove body 302 at the rear end of the slope 301.

[0041] In this embodiment, the electromagnetic coil mounting seat 3 is fixedly connected to the gun body 1. During the simulated firing of the gun, there is no relative movement between the electromagnetic coil mounting seat 3 and the gun body 1. The slope 301 and the groove 302 provided on the electromagnetic coil mounting seat 3 are one of the core improvements of this embodiment.

[0042] An electromagnetic coil, wound around the outer ring of the electromagnetic coil mounting seat 3;

[0043] The magnetic rod 4 can be slidably mounted on the inner ring of the electromagnetic coil mounting seat 3. The magnetic rod 4 is fixedly connected to the sliding sleeve 2. An elastic telescopic rod 5 is arranged at the front end of the magnetic rod 4 corresponding to the ramp 301. The elastic telescopic rod 5 is connected to a sliding wheel 7. When the magnetic rod 4 drives the sliding wheel 7 to move backward along the ramp 301, the elastic telescopic rod 5 is compressed. When the magnetic rod 4 drives the sliding wheel 7 to move to the slot 302, the compression of the elastic telescopic rod 5 is released.

[0044] refer to Figure 5In this embodiment, the magnetic bar 4 can freely move forward and backward in the inner circle of the electromagnetic coil mounting seat 3, and the magnetic bar 4 is fixedly connected to the slide 2, so that the magnetic bar 4 and the slide 2 move together along the gun body 1 in the front-back direction. The electromagnetic coil is used to generate a magnetic field after being energized. The magnetic bar 4 itself can emit a magnetic field. Under the interaction of the magnetic bar 4 and the magnetic field of the electromagnetic coil, the magnetic bar 4 can be pushed to move backward of the gun body 1, and the magnetic bar 4 drives the slide 2 to slide backward, thereby simulating the lateral component F1 of the recoil force when the gun is fired.

[0045] At the same time, during the firing of the gun, the rear end of the chamber will tilt slightly downward so that the recoil of the gun contains a small amount of longitudinal component. In this embodiment, the magnetic bar 4 is provided with an elastic telescopic rod 5 and a sliding wheel 7, and the sliding wheel 7 can slide on the bottom surface of the slope 301. During the backward movement of the magnetic bar 4, since the slope 301 gradually rises in the direction behind the gun body 1, the elastic telescopic rod 5 is compressed, and at the same time, the elastic telescopic rod 5 generates a downward force on the slope 301, which is used to simulate the longitudinal component F2 of the recoil when the gun is fired.

[0046] refer to Figure 6 In addition, after the gun is fired, the bullets in the magazine will quickly fill the original position of the shell, and the new bullets will squeeze the shell out from the opening of the slide 2. At this time, the recoil of the gun is manifested as a short-term, slight frustration feeling released in the longitudinal direction. In this embodiment, a groove 302 is provided at the rear end of the slope 301. When the pulley slides to the end of the slope 301, the elastic telescopic rod 5 is compressed to the extreme value. When the pulley falls from the end of the slope 301 into the groove 302, the compression of the elastic telescopic rod 5 is instantly released, thereby simulating the feeling of the shell from the opening of the slide 2 to the trainee's hand.

[0047] In summary, the simulated gun provided in this embodiment can provide a sufficient amount of lateral recoil component and a small amount of longitudinal recoil component during the backward movement of the magnetic rod 4, simulate according to the actual situation of the gun recoil, and provide the feeling of the shell flying out of the slide 2, giving the trainee a close to real gun recoil simulation feeling.

[0048] Furthermore, the slope of the slope 301 is 3-5°.

[0049] The slope of this embodiment is 4°, which, together with the elastic telescopic rod 5, can better simulate the longitudinal micro-component during the firing process of the gun.

[0050] Furthermore, the depth of the groove body 302 is greater than the deepest point of the slope 301 .

[0051] In this embodiment, the depth of the groove body 302 is set so that the elastic telescopic rod 5 can have enough space to be released when it reaches the groove body 302. Further preferably, the bottom surface of the groove body 302 is larger than the bottom position of the roller when the elastic telescopic rod 5 is fully extended, thereby preventing the roller from hitting the bottom surface of the groove body 302 and preventing the feeling other than the recoil of the gun from being given.

[0052] Furthermore, a first elastic member 6 is provided at the front section of the gun body 1, a rear end of the first elastic member 6 is connected to the gun body 1, a front section of the first elastic member 6 is connected to the front end of the slide 2, and the first elastic member 6 is used to provide a rebound force to move the slide 2 forward after the slide 2 moves backward.

[0053] Furthermore, the top end of the elastic telescopic rod 5 is hinged to the magnetic rod 4, and a second elastic member 501 is arranged between the elastic telescopic rod 5 and the magnetic rod 4. When the sliding sleeve 2 rebounds, the elastic telescopic rod 5 swings backward to make the sliding wheel 7 return to the ramp 301, and the second elastic member 501 is used to provide the elastic telescopic rod 5 with a rebound force to make the elastic telescopic rod 5 return to the vertical downward direction.

[0054] refer to Figure 7 In this embodiment, the elastic telescopic rod 5 can swing along its top end, and the second elastic member 501 can be a torsion spring. After the magnetic rod 4 moves to the final limit position, the magnetic rod 4 starts to move forward. At this time, the hinged structure of the elastic telescopic rod 5 can make the elastic telescopic rod 5 swing backward, so that the elastic telescopic rod 5 and the roller pass over the front end surface of the groove body 302 and return to the slope 301. After the magnetic rod 4 continues to move forward, the distance between the magnetic rod 4 and the slope 301 gradually increases, and the elastic telescopic rod 5 returns to the vertical downward position through the second elastic member 501, so as to reset the structure for the next round of simulated recoil.

[0055] Furthermore, the magnetic rod 4 is provided with a placement cavity, the opening of the placement cavity faces downward, the front end face of the placement cavity is perpendicular to the length direction of the magnetic rod 4, and the elastic telescopic rod 5 is arranged on one side of the front end face of the placement cavity, and the front end face of the placement cavity limits the maximum swing angle of the elastic telescopic rod 5.

[0056] The placement cavity of this embodiment is a square slot structure, so that its front end surface can be used as the limit position for the elastic telescopic rod 5 to swing forward, thereby preventing the elastic telescopic rod 5 from swinging forward when the magnetic rod 4 moves backward and losing the effect of providing the longitudinal component of the recoil force.

[0057] Furthermore, it comprises an energy storage battery 8, the shell of the energy storage battery is shaped like the magazine, and the energy storage battery is used to supply power to the electromagnetic coil.

[0058] Furthermore, it includes a trigger button, which is arranged on the gun body 1. After the trigger of the gun body 1 is pressed, the trigger presses the trigger button.

[0059] Furthermore, the elastic telescopic rod 5 comprises a telescopic rod, and a third elastic member is sleeved on the outer periphery of the telescopic rod.

[0060] In this embodiment, the telescopic rod may be composed of a two-section freely movable rod body combination, and the third elastic member may be a spring, which is sleeved on the outer periphery of the telescopic rod.
