Description
Technical field
The present invention is a kind of target frame of dart target body, be meant a kind of tool electric conductivity especially, on the target body surface simultaneously around the induction frame in plural number score district, and it can directly be connected the electrometer subdivision and responds to score.
Background technology
The dartlike weapon motion has become a kind of modern sport sports now and has been fit to the recreation of all kinds of ethnic groups, the demand of its dartboard equipment technique improvement also constantly produces always, at the constantly product design of seeking change and innovation on the market, various magnetic strength dartboard equipment have become one of main flow on the market, though various magnetic strength dartboard equipment are on the market as contest equipment or amusement article, but, the emphasis when how to develop the magnetic strength score dartboard equipment that more meets user's demand and remaining the industry research and development.
Electronics score dartboard on the market mostly only has the magnetic force induction function merely or presses sense of touch to answer two kinds of functions at present:
The pressure sense of touch answers function formula product structure to cooperate the plug in boomerang structure that is commonly referred to as orifice plate, touches in the electronics at its rear with orifice plate to press circuit, and circuits sense goes out different marks and the demonstration of being scored so that electronics presses, and this problem of commonly using the structure existence is:
One, because of its orifice plate is to be movable structure, the stressed size of orifice plate no matter, circuit board as long as it has stressed collision promptly can be moved with the rear presses, and send mistake and count signal, no matter so plant its dartlike weapon boomerang needle body of product with orifice plate and whether insert in the orifice plate, as long as the phenomenon that has the feelings type of collision promptly might score, when even if dartlike weapon boomerang pin behind the bump orifice plate phenomenon of ejection takes place, this orifice plate still can move the circuit board score that touches the rear;
Its two, if power kicks the beam, touch electronic circuit board and score when dartlike weapon boomerang pin inserts orifice plate and be not enough to promote orifice plate, again or the excessive seasonal orifice plate of dartlike weapon boomerang pin projection power can't homing, and the disappearance of score takes place to continue to trigger; Above situation all can produce the facts of erroneous judgement mark, so electronics presses the dartlike weapon target that touches induction type if improvement will not be difficult to use in the match occasion.
The structure that many improvement are then arranged recently as for magnetic force induction formula dartlike weapon target, but most magnetic force induction formula dartlike weapon targets all are utilization magnetic boomerang directive dartboard or inductance dartlike weapon directive magnetic dartboard, the prerequisite of aforementioned two kinds of dartboards induction score all will be equipped with induction coil with respect to each regional outer rim of scoring, again the utilization coil that darting the boomerang position with the output of induction electric signal with as the score standard; Aforementioned two kinds of magnetic force induction formulas dartlike weapon target is no lack of many patents of getting permission, see also Taiwan patent TW00422340 (the boomerang block structure of scoring of responding to really of the electronic flying-dartlike-weapon target is improved) case of Fig. 1, its target piece 10 peripheries are arranged with induction detecting coil 11, and its induction detecting coil 11 utilizes elongated end 110 to engage with electronic circuit board, and dartboard uses the multiple tracks induction detecting coil 11 of each piece target piece 10 all side to produce induction score function, and aforementioned target piece 10 can be responded to the 11 sensitive inductions of detecting coil and carry out the automatic score computing; But still have following problems to produce after the above-mentioned traditional product practicality:
One, multiple tracks induction detecting coil 11 windings of this dartboard commonly used, elongated end 110 assembling mode complexity, increase operating cost, in order to allow elongated end 110 can smooth and easyly lead to numerous and diverse assembling mating component and the technology of more needing, if target piece 10 does not have suitable safeguard measure, the dartlike weapon that the user penetrates is also penetrated bad respond to detecting coil 11 or elongated end 110 through regular meeting, and produces wrong score or inefficacy;
Its two, its target piece 10 peripheries are arranged with multiple tracks induction detecting coil 11, not only induction detecting coil 11 material costs are higher, and multiple tracks winding work also can form the burden on the operating cost;
They are three years old, behind the target piece 10 windings induction detecting coil 11, still must assemblies such as target piece 10, target frame be assembled on the target body one by one, the assembly working between this target piece 10 and the dartboard more can increase the activity duration again, so commonly use assembly assembling, quantitatively all very complicated;
Its four, target piece 10 is easy to be passed by metal dartlike weapon, and the dartlike weapon of injecting at a high speed more may wear the induction detecting coil of penetrating around the damage winding 11, even causes 11 errors of induction detecting coil or lost efficacy.
Because the cost problems affect of above-mentioned magnetic force induction formula dartboard is very huge, so improvement that has this case applicant to propose to be correlated with, No. the 00373723rd, Taiwan patent " electric dart target target body induction structure " as Fig. 2, it directly is embedded the target frame 13 of hollow on target body 12 surfaces, and allows 15 windings of multiple tracks induction coil in the hollow space 14 that target frame 13 bottoms are offered; Use structure and carry out the magnetic force induction function, and promote inductive effects correct when throwing so that the dartlike weapon target to be provided; Though this kind structure-improved commonly used can avoid material cost and dartlike weapon that coil twines assembling to wear the facts of penetrating damage, this structure still has following problem:
One; induction coil 15 must have 13 protections of plastics target frame; and plastics target frame 13 still can be by the damage of metal dartlike weapon under long-term the use; not only the dartlike weapon of injecting at a high speed can pass hollow space 14 equally; cause induction coil 15 errors of score district or inefficacy; and dartlike weapon injects plastics target frame 13 and can cause score invalid, and impaired plastics target frame 13 outward appearances allow the user be difficult to continue to use especially.
They are two years old; multiple tracks induction coil 15 is that winding is in the hollow space 14 that target frame 13 bottoms are offered; so when target frame 13 makes up with target body 12; these induction coil 15 regular meetings come off or by structure cramping (assembling is not easy); and two ends of each road induction coil 15 all must be connected with the Circuits System at target body 12 rears; but this connected mode can allow whole target surface be covered with complicated circuit (for example: score district induction coil 15 2 ends of the top must winding could outwards pass by whole target surface); and all can twine the complicated induction coil of multiple tracks 15 in each hollow space 14; not only the cost of coil still can increase, and the producer's built-up time; the operational difficulty degree also can increase.
Its three, induction coil 15 must have plastics target frame 13 protection, and the ejaculation manufacturing cost height of plastics target frame 13, and target body 12 surfaces are in order to be embedded the target frame 13 of hollow, this target body 12 must carry out complicated fluting operation, produces the problem that cost can't reduce.
In order effectively to solve aforementioned issues associated, research and development technology and experience that creator of the present invention was accumulated in dartlike weapon sports equipment field based on the past, set about because of the science angle from the people who simplifies member, simplification assembling, research and develop this innovation in conjunction with many years of experience finally.
