Description

Speed measuring mechanism of electromagnetic transmitting device

Technical Field

The utility model belongs to the technical field of electromagnetic emission, and particularly relates to a speed measuring mechanism of an electromagnetic emission device.

Background

Nonmetallic ammunition made of nonmetallic materials (such as plastics, rubber, liquid and the like) is a common non-lethal ammunition, also called anti-riot ammunition, and is used for driving targets in riot, so that the targets can lose mobility. In general, a non-lethal ammunition is one that can crash a target but is insufficient to cause the target to be severely injured or die.

Most of the nonmetallic elastomers are launched by means of a gun launcher at present, but the gun launcher only launches nonmetallic elastomers with fixed specifications, and the universality is poor. In addition, because the nonmetallic projectile body launched by the gun launcher is ignited by the ejector pin by utilizing the thrust projectile body carried by the nonmetallic projectile body, the nonmetallic projectile body is launched out by means of instant explosion pressure, so that the launching speed of the nonmetallic projectile body is always fixed, the speed is high, and serious injury and even death are still possible.

Therefore, an electromagnetic emission device with adjustable and controllable emission speed is available, which follows the law of electromagnetic induction and Lenz's law. For example, the application number is 202011137713.4, the name is Chinese patent invention of a magneto-resistive type electromagnetic gun with controllable gun shell acceleration distance and a control method, the magneto-resistive type electromagnetic gun with controllable gun shell acceleration distance comprises a gun barrel, a gun shell, a main circuit and a control circuit, the control circuit comprises a singlechip and a MOSFET driving circuit, the control of the MOSFET in the main circuit by a controller is used for realizing accurate control of charge and discharge time of an acceleration coil of the electromagnetic gun so as to actively change the maintenance time of a strong magnetic field in the coil, the change of the magnetic field of the acceleration coil has a direct relation with the acceleration distance of the gun shell, the relation between the coil power-on time and the gun shell firing distance is obtained through multiple tests, and finally, the gun shell acceleration distance is controlled by utilizing the relation to finally change the firing distance of the gun shell. And a control method of the reluctance type electromagnetic gun with the controllable shell acceleration distance is provided. The invention can effectively solve the problems of difficult capacity selection, low acceleration efficiency and the like of the conventional reluctance type coil cannon, and improves the maximum exit speed of the cannon; meanwhile, the controllable shell firing range can be realized under the condition of not adding other control devices.

The magneto-resistive electromagnetic gun with controllable shell acceleration distance solves the problem of controllable shooting range of the shooting shell, but the shooting speed of the nonmetallic shell can directly influence the shooting range and the striking effect, so that the magneto-resistive electromagnetic gun has important significance for researching the shooting speed of the nonmetallic shell, but the electromagnetic shooting device can generate a strong magnetic field to interfere with a common speed detection sensor, so that the electromagnetic gun cannot be used. Accordingly, the present application is directed to solving the issue of emission speed detection when an electromagnetic emission device emits a non-metallic projectile.

In view of this, the present utility model is specifically proposed.

Example 1

Referring to fig. 1 to 8, an electromagnetic emission apparatus of the present embodiment includes:

A non-metallic elastomer (not shown);

a loading armature 600 comprising a metal housing 601 having an open loading chamber 604 therein, said non-metallic elastomer being loaded into said loading chamber 604;

the armature driving mechanism comprises a driving power supply, a driving coil 207 and an accelerating tube 204, wherein the driving power supply is connected with the driving coil 207 in a circuit manner, the driving coil 207 is internally provided with a driving coil tube 202, and the accelerating tube 204 is in butt joint communication with the driving coil tube 202;

a declutching mechanism including a declutching sleeve 501 having a declutching step inside, said declutching sleeve 501 being in abutting communication with said accelerating tube 204;

the loading armature 600 is mounted in the driving coil pipe 202 and is close to one end of the accelerating tube 204, pulse current is provided to the driving coil 207 by controlling a driving power supply, the loading armature 600 is launched under the driving of the driving coil 207, enters the pivot release sleeve 501 after being accelerated by the accelerating tube 204 and is blocked by the pivot release step, and the nonmetallic projectile body is launched after being separated from the loading armature 600.

The electromagnetic emission device of the embodiment realizes the emission of the nonmetallic projectile body by utilizing electromagnetic driving, and the electromagnetic driving principle is as follows: the magnetic coupling mechanism between the driving coil 207 and the metal casing 601 of the loading armature 600 works, and the basic law of the magnetic coupling mechanism is still the law of electromagnetic induction and Lenz law, and the driving power switch is closed to supply pulse current to the driving coil 207, so that the driving coil 207 which is supplied with the pulse current generates a changed magnetic field, the metal casing 601 of the loading armature 600 generates induced current, the induced current generated by the metal casing 601 generates an induced magnetic field, and the Lenz law indicates that the magnetic field of the induced current always blocks the change of magnetic flux which causes the induced current, so that the magnetic field generated by the driving coil 207 and the induced magnetic field of the metal casing 601 repel each other. Since the magnetic induction intensity of the driving coil 207 decreases from the center to the two sides, if the center surface of the loading armature 600 is on the right side of the center surface of the driving coil 207, the loading armature 600 receives a repulsive force to the right; if the center plane of the loading armature 600 is located on the left side of the center plane of the driving coil 207, the loading armature 600 receives a repulsive force to the left.

Therefore, the electromagnetic emission device of the present embodiment has the following advantages:

1. according to the electromagnetic emission device, the emission of the nonmetal projectile body is realized by utilizing electromagnetic driving, the emission speed of the nonmetal projectile body can be controlled by controlling the power-on quantity of the armature driving mechanism, and the requirements of various use scenes are met.

3. The electromagnetic emission device of the embodiment can be used as experimental equipment for researching target striking effects under different types and different emission speeds because the emission speed is controllable and the device can be used for compatibly emitting nonmetallic elastomers of different types.

In the electromagnetic emission device of the present embodiment, separation of the nonmetallic elastomer from the loading armature 600 is achieved by electromagnetic driving, so, as shown in fig. 4, the pivot release mechanism of the present embodiment includes a buffer sleeve 503, a first end of the pivot release sleeve 501 is in butt joint communication with the accelerating tube 204, the buffer sleeve 503 is tightly sleeved in a second end of the pivot release sleeve 501, and a pivot release step is formed in the pivot release sleeve 501; the inner diameter of the de-pivoting sleeve 501 is greater than or equal to the inner diameter of the accelerating tube 204, and the inner diameter of the buffer sleeve 503 is smaller than the outer diameter of the loading armature 600 and greater than the inner diameter of the loading armature 600. In this way, the loading armature 600 loaded with the nonmetallic elastomer is accelerated by the drive coil 207, and when the loading armature 600 moves into the release sleeve 501 through the accelerating tube 204, the release step stops to continue moving, and the nonmetallic elastomer continues to move due to inertia, so that the separation from the loading armature 600 is realized.

Further, an electromagnetic emission device of the present embodiment includes an emission tube 400, one end of the emission tube 400 is inserted into the second end of the release sleeve 501, and the nonmetallic elastomer is emitted from the emission tube 400 after being separated from the loading armature 600 in the release sleeve 501; the launch tube 400 is in abutting communication with the buffer sleeve 503, the launch tube 400 having an inner diameter equal to or slightly larger than the inner diameter of the buffer sleeve 503.

Referring to fig. 3 and 4, in an electromagnetic emission device of the present embodiment, the armature driving mechanism includes a positioning post 206, the positioning post 206 is inserted into one end of the driving coil tube 202 of the driving coil 207, which is far away from the accelerating tube 204, and the loading armature 600 is loaded in the driving coil tube 202 and is abutted and positioned by the positioning post 206. Since the loading armature 600 of the present embodiment needs to be placed on one side (left or right of the off-center position) of the driving coil tube 202 of the driving coil 207 to achieve electromagnetic driving based on lenz's law, if an initial position error of the loading armature 600 will affect the firing, the present embodiment determines whether the loading armature 600 is loaded in place by the positioning posts 206 after the loading armature 600 is loaded into the driving coil tube 202 of the driving coil 207. Specifically, if the loading armature 600 is loaded from the left end of the driving coil tube 202 of the driving coil 207, the positioning column 206 is inserted from the right end of the driving coil tube 202 of the driving coil 207, and then the loading armature 600 is loaded from the left end of the driving coil tube 202 of the driving coil 207 until the loading armature is abutted against the end of the positioning column 206, so that loading is completed; if the loading armature 600 is installed from the right end of the driving coil pipe 202 of the driving coil 207, the loading armature 600 is installed into the right end of the driving coil pipe 202 of the driving coil 207, and then the positioning post 206 is inserted from the right end of the driving coil pipe 202 of the driving coil 207, and after the positioning post 206 is completely inserted, the positioning post 206 pushes the loading armature 600 to the firing position.

As an alternative implementation of this embodiment, in order to better position the loading armature 600, in this embodiment, the positioning post 206 has a positioning groove 206A at a first end and a limiting convex ring 206B at a second end, the first end of the positioning post 206 is inserted into the driving coil bobbin 202, the tail end of the loading armature 600 is in a limiting abutment with the positioning groove 206A, and the limiting convex ring 206B on the second end of the positioning post 206 is in a limiting abutment with the end of the driving coil bobbin 202.

As an alternative implementation of this embodiment, referring to fig. 2-4, an accelerating tube filling opening 205 is formed on the upper side of the tube wall of the accelerating tube 204, and the loading armature 600 loaded with the nonmetallic elastomer is loaded into the driving coil bobbin 202 through the accelerating tube filling opening 205.

Since the loading armature 600 and the nonmetallic elastomer are separated under the action of the pivot removing mechanism, the separated loading armature 600 is retained in the pivot removing sleeve 501 or the accelerating tube 204, so that in order to recover the loading armature 600, for the next nonmetallic elastomer emission, as shown in fig. 15, an electromagnetic emission device of the embodiment comprises a towing rope 700, wherein one end of the towing rope 700 is fixed at the tail end of the loading armature 600, and the other end extends out of the driving coil tube 202 of the driving coil 207.

Referring to fig. 1 and 2, the armature driving mechanism includes a coil shield 201, the coil shield 201 covers the driving coil 207, the de-pivoted mechanism includes a elastomer-filled shield 208, and the elastomer-filled shield 208 covers the accelerating tube 204 and the de-pivoted sleeve; the shell filling opening 208A is formed in the shell filling shielding cover 208, a drawing plate is mounted on the shell filling opening 208A, and the shell filling opening 208A is opened and closed by drawing the drawing plate. The side wall of the elastomer-filled shielding case 208 is provided with an accelerating tube opening 208B, and the accelerating tube 204 passes through the accelerating tube opening 208B.

Referring to fig. 1-4 and 20, an electromagnetic emission device of the present embodiment includes a speed measuring mechanism 300, where the speed measuring mechanism 300 includes an electromagnetic shielding cover 301, speed measuring sensors (303, 304) and a dc power supply 307, the electromagnetic shielding cover 301 is disposed on an emission path of the nonmetallic elastomer, the speed measuring sensors (303, 304) are installed in the electromagnetic shielding cover 301, and the dc power supply 307 is electrically connected with the speed measuring sensors (303, 304). The speed measuring mechanism 300 of the embodiment can detect the emission speed of the nonmetal projectile body, and evaluate the striking effect of the nonmetal projectile body of the same type at various emission speeds according to the damage caused by the nonmetal projectile body on an experimental target.

An electromagnetic emission device of this embodiment has the following operation logic:

a non-metallic elastomer is incorporated into loading armature 600 (the housing is made of aluminum material).

The pulling plate on the loading body shield 208 is opened, and the loading armature 600 loaded with the nonmetallic body is manually pushed into one side port of the driving coil 207 (according to the coil driving principle, the armature moves leftwards, and needs to be placed close to the left side of the center of the driving coil 207) through the loading opening 208A of the shield body and then through the accelerating tube loading opening 205 formed in the accelerating tube 204.

When the bottom end of the loading armature 600 contacts the positioning posts 206, the drawer is closed after loading is completed.

Energizing and discharging drive coil 207, loading armature 600 drives the nonmetallic projectile to accelerate to the left. The non-metal projectile flows through the accelerating tube 204, when the loading armature 600 contacts the de-armature mechanism, the loading armature 600 is blocked and decelerated, the non-metal projectile is not acted by the de-armature mechanism, and continuously moves forward under the action of inertia, the non-metal projectile is separated from the loading armature 600, the loading armature 600 is retained, the non-metal projectile continuously moves forward, enters the launching tube 400, passes through the speed measuring mechanism 300, and finally flies to the target bin to strike the target.

In addition, after the loading armature 600 of the present embodiment is loaded with the nonmetallic elastomer, the loading armature 600 is pushed to a predetermined position by the positioning column 206 from the right side of the driving coil, and then the driving coil is electrically fired.

Example two

Referring to fig. 6-13, the present embodiment provides a loading armature 600 for electromagnetically launching a non-metallic projectile comprising a metal housing 601 having an open loading chamber 604 for loading the non-metallic projectile; the closed end of the metal housing 601 defines a through opening 602 that communicates with the loading chamber 604. Thus, during loading of the non-metallic elastomer into loading chamber 604 through the open end of metal housing 601, through-opening 602 maintains loading chamber 604 in communication with the environment, avoiding the non-metallic elastomer from making loading chamber 604 a closed chamber, and avoiding the air pressure within the closed chamber from affecting loading of the non-metallic elastomer.

Referring to fig. 6-8, the nonmetallic elastomer according to this embodiment is a stick-shaped or spherical bullet, the loading chamber 604 in the metal housing 601 is a cylindrical chamber, and the cross-sectional diameter Dt of the nonmetallic elastomer and the inner diameter Dr of the loading chamber 604 satisfy: dr is 1/2, dt is less than or equal to Dr. This ensures that the non-metallic elastomer can be successfully loaded into the loading chamber 604 of the metal housing 601 and remains relatively stable between the loaded non-metallic elastomer and the loading chamber 604 after loading, avoiding the impact of a large amount of movable frames of the non-metallic elastomer on the stability of the firing process.

As can be seen from the foregoing embodiments, the loading armature of the present embodiment requires a certain size for the loaded nonmetallic elastomer, but for nonmetallic elastomer with smaller size, the loading armature for electromagnetically launching nonmetallic elastomer of the present embodiment includes a flexible filler (e.g., supported by sponge, foam, etc.), the flexible filler has a circular ring structure, the nonmetallic elastomer is a stick-shaped or spherical shell, the loading chamber in the metal housing is a cylindrical chamber, and when the cross-sectional diameter Dt of the nonmetallic elastomer and the inner diameter Dr of the loading chamber satisfy: and when Dt is less than 1/2 x Dr, the flexible filling body is filled in a gap between the nonmetallic elastomer and the metal shell. According to the loading armature for the electromagnetic emission nonmetallic elastomer, loading of nonmetallic elastomer with smaller size specification is achieved through adding the flexible filling body, when nonmetallic elastomer with larger size specification is loaded, the flexible filling body is removed, and compatibility of loading of nonmetallic elastomer with different size specification by the loading armature is improved.

Further, the conventional nonmetallic elastomer further includes a non-fixed form such as a water bomb, a flexible bomb, etc., and in order to be compatible with the loading of this type of nonmetallic elastomer, a loading armature for electromagnetically launching the nonmetallic elastomer of this embodiment includes a clamping member 605 disposed in the open end of the loading chamber 604, where the nonmetallic elastomer is an irregular-shaped elastomer (such as a sponge bomb, a cloth-bag bomb, etc.), and the irregular-shaped elastomer is clamped and fixed in the loading chamber 604 by the clamping member 605.

Specifically, the clamping member 605 in this embodiment is an elastic card, a plurality of elastic cards are circumferentially distributed at the open end of the loading chamber 604, a first end of each elastic card is blocked and limited outside the open end of the loading chamber 604, a second end of each elastic card extends into the open end of the loading chamber 604 and extends toward the center, and the irregular elastomer is clamped and fixed by the second ends of the plurality of elastic cards. According to the embodiment, four or six elastic cards are added, so that the elastic body is ensured to be at the center position aiming at the irregular-shaped elastic body; in yet another aspect, the elastic tabs grip the irregular shaped projectile (e.g., sponge, cloth bag, etc.) around the space to prevent the irregular shaped projectile from falling off when the loading armature 600 suddenly accelerates the irregular shaped projectile.

Referring to fig. 11, as an alternative implementation manner of the present embodiment, a first end of the elastic card is a first horizontal arm 605A, a second end of the elastic card is a second horizontal arm 605C, and the elastic card further includes an inclined connecting arm 605B that connects the first horizontal arm 605A and the second horizontal arm 605C.

Further, referring to fig. 12 and 13, a loading armature for electromagnetically launching a nonmetallic elastomer according to this embodiment includes a compression spring 606, one end of the compression spring 606 is fixed at the second end of the elastic card, the other end of the compression spring 606 abuts against the inner wall of the loading chamber 604, and the compression spring 606 is in a compressed state after the irregularly-shaped elastomer is loaded. A loading armature for electromagnetically launched nonmetallic elastomers of this embodiment can increase the clamping force of the elastic card to the irregularly shaped elastomer by compressing the spring 606.
