Description

Technical field

The invention relates to an electronic target dart apparatus, in particular to an electronic target dart apparatus which realizes automatic scoring by using a magnetic induction method.

Background technique

Most electronic target darts in the prior art use touch to achieve automatic scoring, that is, a number of target blocks are made according to the size and shape of the target surface count section, and each target block is combined into a target surface. When the dart hits the corresponding count section, After the target block of the target, the target block of the metering section vibrates backwards to touch the corresponding switch, and the circuit is conducted to obtain the corresponding scoring signal. The target surface of this dart target composed of several target blocks, the target block and the target Looseness is likely to occur between the bodies, on the one hand, causing the target surface to be unsightly, and on the other hand, the touch generated by a dart hitting a target block may also cause vibration of other target blocks, resulting in chaotic scoring. In order to solve the above-mentioned shortcomings, I have proposed a new triggering method. See the public patent CN00267103.4 "A magnetic induction automatic scoring device for dart targets", that is, using the principle of magnetic induction and corresponding positions on the target scoring grid. There is a scoring grid frame. Each frame is equipped with a magnetic induction coil. The leads of each magnetic induction coil are connected to the scoring circuit, and the dart tip or dart tip and dart body are also designed as magnetic bodies. 'In use, the instantaneous electrical signal generated by the magnetic line cutting coil of the magnetic dart when it is injected into the dart target is used as the basis for scoring, so that automatic scoring using the magnetic induction method is achieved. It can not only ensure the integrity of the target surface of the dart target and increase its aesthetics, but also avoid the scoring phenomenon caused by misoperation. However, since automatic scoring is achieved by magnetic induction, a magnetic induction electric signal of a certain strength must be obtained, and the magnetic The strength of the induced electrical signal depends on three factors, such as the magnetic line density, the number of coil turns, and the cutting speed. The strength of the magnetic induction electric signal is proportional to the magnetic line density, the number of coil turns, and the cutting speed. In order to obtain an electrical signal of a certain strength, the The number of turns usually needs more than 2 turns, and this kind of coil is generally made by three-dimensional processing technology. If it is wound by enameled wire, this makes it difficult to make the dart target and complicates the manufacturing process. The degree is relatively high. A

Summary of the invention

The purpose of the present invention is to overcome the shortcomings of the prior art, and provide an electronic target dart apparatus for making a coil with a one-turn coil or a two-dimensional plane processing technology, so that the dart target manufacturing process of the dart apparatus is simple and easy to implement. And you can get better results.

The technical solution adopted by the present invention to solve its technical problems is: an electronic target darts device composed of a dart and a dart target;

In the dart, a magnetic material body is provided at the dart tip, and the dart tip is flat; the dart target has a built-in scoring circuit, and includes a target surface layer, and the target surface layer is printed with A plurality of grid areas, each grid area is set as a corresponding count area; an insulating layer; a thin film printed coil layer, which is a printed circuit made of a two-dimensional plane processing technology, a thin film The grid areas of the printed coil layer opposite to the target surface layer are printed with independent single-turn coils, and the output of each coil is connected to the scoring circuit. The adsorption layer is provided with a plurality of ferrous material bodies corresponding to the target surface compartment; a target bottom layer; the target surface layer, the insulating layer, the thin-film printed coil layer, the adsorption layer, and the target bottom layer are sequentially connected and fixed.

The adsorption layer further includes an insulating frame, and the shape of the frame of the insulating frame is along the target. The grid lines printed on the surface layer are correspondingly arranged, and each grid frame of the insulating frame body is embedded with a ferrous material body adapted to its size.

The dart target may further be provided with a plastic film layer, the plastic film layer is provided between the adsorption layer and the target bottom layer, and the adsorption layer, the plastic film layer, and the target bottom layer are sequentially connected and fixed.

The dart target is also provided with a frame or a reel, and a scoring circuit is installed therein. A display and a plurality of setting buttons are arranged on the front side of the dart target, and the frame or the reel is connected to each layer of a fixed phase.

The target surface layer may be a single structure made of a flannel material.

The insulating layer is an insulating plastic film.

The single-turn printed coil of each grid area is printed along the edge of the grid area, and a certain distance is set between the coil and the coil of the adjacent grid area.

The diameter of the tip surface of the dart board is slightly larger than the distance between adjacent coils.

The target bottom layer may be a single structure made of a flannel material.

The ferrous material body may be a soft iron sheet or an iron sheet or iron powder adhered to the insulating surface. The insulating frame is a single frame made of rubber.

When making, first divide the grid area on the target surface. The formation of the grid area can be either by coating the target surface layer with grid lines to form a number of grid areas on the target surface; The range of the location of the grid area is painted with corresponding distinguishing colors, so that a certain distance is left between adjacent distinguishing color blocks; each sub-grid area corresponds to a corresponding score; between the target surface layer and the thin-film printed coil layer An insulation layer is provided to ensure the insulation of the thin-film printed coil from the outside; the coil of the thin-film printed coil layer is arranged according to the grid area of the target surface layer, that is, an independent printed coil circuit is provided in each grid area. Coils are made by printing. There is a certain distance between the coils, and the coils of each coil are led from the target surface and connected to the scoring circuit, so that the signals induced by each coil can be sent to the scoring circuit for score calculation; the adsorption layer can be insulated The frame body and the ferrous material body are formed, and the range of the coil is consistent with the edge of the ferrous material body below. The target surface layer, the insulating layer, the thin-film printed coil layer, the adsorption layer, and the target bottom layer are fixed to form a target surface. The target surface is fixed to the frame or the scroll. When fixed, the target surface can be put into the frame or The opening slot of the reel is fixed by screws. At the same time, the outlet of the target surface is connected to the scoring circuit provided on the frame or reel. A display and several setting buttons are provided on the front of the frame or reel to display the score. Situation and game settings.

When in use, hang the entire dart target on the wall, and then perform dart game activities. During the activity, hold the dart and shoot it at the dart target. Because the tip of the dart dart is provided with a magnetic material body, the magnetic properties of the tip of the dart dart are used. The ferrous material body of the adsorption layer of the material body and the dart target can attract the dart to the dart target under the magnetic and iron attraction; when the dart flies to the target surface, the iron and the magnetic attraction The end surface of the dart dart tip will be attracted to the dart target, because the winding range of each coil is consistent with the edge of the ferrous material body below, and the diameter of the dart tip surface is slightly larger than the distance between adjacent coils, so It can be ensured that when the dart tip of the dart is close to the target surface of the dart target, the dart tip can always be biased into the coil with a larger suction force, and will not be sucked on the dividing line or the distance between adjacent coils. The moment the dart tip touches the dart target, the magnetic field lines formed by the magnetic field at the end of the dartboard will cut the coil. This cutting of the magnetic field lines causes the coil to generate an electrical signal. The strength of the magnetic induction electrical signal depends on the magnetic field line density and the coil. The number of turns and the cutting speed are three factors, and the strength of the magnetic induction electric signal is proportional to the magnetic field density, the number of coil turns and the cutting speed. After the dart tip is made of a flat magnetic material body, The density of magnetic lines of force has greatly increased. As long as the number of turns of the coil is only one, an electrical signal of a certain strength can be obtained to achieve automatic scoring. This is also the basis for making a coil of a thin film printed coil layer by printing. The electric signal generated by the coil is sent to the scoring circuit, and the signal that the dart touches the area is sent to the scoring circuit for scoring; and the dart is adsorbed in different positions or different recording areas, so that the film is printed on the coil layer Different coils generate magnetic induction, and the corresponding coil circuit generates an electrical signal, so that the signal reflecting the score is sent to the scoring circuit for scoring. When a dart is attracted to the target surface and is stationary, the coil will not generate electromotive force because there is no speed at rest, so the coil will no longer generate an electrical signal. In this way, each dart can only make the coil have a moment when it hits the target body of the dart target. Electric signals are generated, and no electric signals are generated after stationary, which has no effect on the scoring of subsequent darts, so that darts and darts will not interfere with each other and confuse each other, ensuring the accuracy of scoring. The electrical signals generated by each dart touching the target surface are sent to the scoring circuit in turn, and the scoring circuit calculates them. By setting different entertainment methods, the corresponding scoring results can be obtained.

The beneficial effect of the present invention is that, because a target surface layer, an insulating layer, and a thin-film printed coil layer are used, the dart dart tip can be attracted to the dart target's adsorption layer and the target bottom layer, and the target surface layer, the insulating layer, and the thin film are printed. The coil layer, the adsorption layer, and the bottom layer of the target are fixedly connected to form the target surface of the dart target, especially because the thin-film printed coil layer is used as the signal trigger area after the dart hits the dart target, making the production process of the dart target simple and easy. Realized, it can be made into printed coils required for dart targets by plane processing technology with two degrees of space, and it can bring better use effect; because the magnetic material body is set at the dart tip of the dart, and the dart's The tip of the dart is flat, which can not only easily adsorb the target surface of the dart target, but also greatly increase the magnetic line density of its end, so that only 1 turn of the coil can obtain the electric signal of the required strength to achieve automatic The scoring enables the single-turn coil circuit formed by the thin-film printed coil layer to be used. Because the dart target is provided with an adsorption layer capable of attracting the dart tip to the dart target, and the ferrous material body of the adsorption layer It is correspondingly set relative to the target area grid zone, so as to ensure the dart target's adsorption effect on the dart; because a certain distance is set between the coil and the coil of the adjacent grid zone, and the diameter of the dart tip face Make it slightly larger than the distance between adjacent coils, so that when the dart tip is close to the target surface of the dart target, it can always be biased into the coil that attracts more to it, instead of sucking on the ruled line or adjacent The distance between the coils; this type of electronic target is equipped with a magnetic material body at the dart tip of the dart, and the coil of the dart target is cut by the magnetic lines of force generated by the magnetic material at the end of the dart to make the coil generate an induction signal for automatic scoring. Darts equipment, which not only ensures the overall aesthetics of the target surface of the dart target, but also achieves better use effects.

The diameter of the dart tip surface of the dart 1 is slightly larger than the distance between adjacent coils 4.

When making, first divide the grid area 3 on the target surface. The formation of the grid area 3 can either be printed on the target surface layer with grid lines to form a number of grid areas on the target surface; The range of the position of one grid area is painted with corresponding distinguishing colors, so that a certain distance is left between adjacent distinguishing color blocks; each grid area corresponds to a corresponding score; in the target surface layer 221 and An insulation layer 222 is provided between the thin-film printed coil layers 223 to ensure the insulation of the thin-film printed coils from the outside; the coil 4 of the thin-film printed coil layers 223 is arranged according to the division area 3 of the target surface layer 221, that is, each division area There is an independent printed coil 4 inside, and each coil 4 is a single-turn coil. The coil 4 is printed along the edge of the compartment where it is located. There is a certain distance between the coil 4 and the coil in the adjacent compartment. The output of each coil 4 is led from the target surface and connected to the scoring circuit so that the signal induced by each coil 4 can be sent to the scoring circuit for score calculation. The adsorption layer 224 can be composed of an insulating frame and a ferrous material. The body 5 is composed of an insulating frame body corresponding to each grid region of the target surface layer 221, and is ferrous. The material body 5 can be a soft iron sheet, and the ferrous material body 5 is embedded in the insulating frame body to form the adsorption layer 224, which can ensure the absorption of The ferrous material body 5 of the cover layer 224 corresponds to the coil 4 of the thin film printed coil layer 223, that is, each coil 4 of the thin film printed coil layer 223 corresponds to a piece of ferrous material body 5, and the range of the coil 4 is below it. The edges of the ferrous material body 5 coincide.

At the same time, the outlet of the target surface is connected with the scoring circuit provided on the reel 21. A display 211 and several settings are provided on the front of the reel 21 Button 212 is used to display the scoring situation and game settings.

When in use, the entire dart target is hung on the wall, and then the dart game activity can be performed. During the activity, the dart 1 is shot toward the dart target 2. Since the dart '1 has a magnetic material body 11 at the tip, a dart 1 dart is used The magnetic material body 11 at the tip and the ferrous material body 5 of the adsorption layer 224 of the dart target 2 can attract dart 1 to dart target 2 under the action of magnetic and iron attraction; when dart 1 flies to dart target 2 target When the surface is attracted by iron and magnetism, the end surface of the dart tip of dart 1 will be attracted to dart target 2, because the range of each coil 4 is consistent with the edge of ferrous material body 5 below it, and dart 1 dart The diameter of the tip surface is slightly larger than the distance between adjacent coils 4, so that when the dart tip of dart 1 approaches the target surface of dart target 2, it can always be biased into the coil 4 that has a larger suction force, and will not be sucked into the coil 4 On the grid or at the distance between adjacent coils 4.

Depends on three factors: magnetic field density, coil turns and cutting speed, and the strength of magnetic induction electrical signal and magnetic field line density, coil turns and cutting speed

? In direct proportion, after setting the dart 1 dart tip to be a flat magnetic material body, the magnetic field line density of its end face is greatly increased. As long as the number of turns of the coil is 1 turn, a certain strength electric signal can be obtained to achieve automatic scoring.

When the dart 1 is attracted to the target surface 22 and is stationary, since the dart 1 does not move, the coil 4 will no longer generate an electrical signal. In this way, each dart can only electrify the coil at the moment it hits the target body of the dart target. The signal is generated, and no electrical signal is generated after stationary, which has no effect on the scoring of the subsequent dart 1, so that the dart and the dart will not interfere with each other and confuse each other, thereby ensuring the accuracy of the scoring. The electrical signals generated by each dart 1 touching the target surface 22 are sent to the scoring circuit in turn, and are calculated by the scoring circuit. By setting different entertainment methods, corresponding scoring results can be obtained.
