Technical Field

The invention relates to the technical field of electronic dartboard, in particular to a magnetic induction coil wiring structure and a magnetic induction type electronic target.

Background

Dart movements originated in england in the 15 th century, and soldiers thrown darts at battle gaps to stumps, and later evolved into a small indoor sport. At present, the dart targets popular in the market are various, including paper targets, plastic targets and hemp targets, wherein the hemp targets occupy the leading position, and the hemp targets are also professional targets for various international dart games.

The international dart game target surface partition is shown in fig. 1. The target surface is divided into subareas by a subarea isolation net which is arranged in the target body, and the existing subarea isolation net comprises a circular net, a triangular net and a knife net, wherein the knife net occupies small effective scoring space of the target surface and occupies absolute advantage.

In the scoring mode, the dartboard is divided into a manual scoring dartboard and an electronic scoring dartboard (an electronic target for short). The existing electronic target is mainly realized by two modes, namely pressure induction scoring based on a film sensor and electromagnetic induction scoring based on an electrified coil.

The electronic target for pressure induction scoring is a box-type target block with each section made into an independent one, when the target block is forced to move towards the direction of the bottom plate, the salient points of the film sensor arranged between the bottom plate and the target block form a channel because of bearing a certain pressure, thereby realizing scoring. The disadvantage of this kind of electronic target is that the box body of the box target block occupies a certain target surface space, and in addition, a gap enough for relative movement is left between the adjacent box bodies, so that the effective target surface scoring space is further reduced, and the dart drop rate is increased.

Electronic targets designed based on the electromagnetic induction principle of electrified coils have been long born and can be inquired on networks, the earliest domestic patent literature about magnetic induction type dartboard should be the utility model patent CN 2373132Y issued and disclosed by the national Bureau of 2000-4-12-month, and an induction structure of the target body of the electronic dartboard is disclosed.

The national Bureau discloses a magnetic induction type electronic scoring sisal dart target in the utility model CN 2795792Y granted and disclosed in 2006, 7, 12, and the target surface is divided into 82 independent scoring areas, and an annular wide thin sheet winding frame is arranged at the edge of each independent area, and the winding frame top is provided with a wire groove for accommodating an induction coil, and the whole structure is similar to a box-shaped target block in a pressure induction electronic target.

In the above two magnetic induction electronic target design schemes, the technical problem of the pressure induction electronic target is not overcome, only the induction mode different from the pressure induction is provided, and the problems of complicated wiring result, inconvenience in processing and manufacturing and high implementation cost exist.

Disclosure of Invention

In view of the above problems, the present invention provides a magnetic induction coil wiring structure and a magnetic induction electronic target, which facilitate wiring and processing and occupy a small effective scoring space on the target surface.

The invention protects a magnetic induction coil wiring structure.A sheet-shaped bulge extending into a target body is arranged at the position of a bottom plate corresponding to each partition line, and the sheet-shaped bulge corresponding to the radial partition line and the sheet-shaped bulge corresponding to the circumferential partition line are mutually penetrated to form a net-shaped bulge for accommodating a magnetic induction coil group; and leads at two ends of each magnetic induction coil penetrate through the bottom plate and are connected to the circuit board.

Preferably, the cross section of the flaky bulge is a trapezoid with a wide bottom and a narrow top, and the length of the upper bottom of the trapezoid is equal to the thickness of the knife line net; the reticular bulge and the bottom plate are integrally formed by injection molding.

Preferably, a groove is formed in the top of the sheet-shaped protrusion, and the magnetic induction coil is embedded into the groove; or a cavity is arranged inside the flaky bulge, and the magnetic induction coil is placed in the cavity and then is glued and fixed; or the magnetic induction coil is placed in an injection mold and directly injected on the top end of the flaky bulge.

Preferably, the magnetic induction coil set comprises 5 loop wire coils and 10 radial wire coils; the 5 loop coils are respectively a 50-time loop coil, a 25-time loop coil, a 3-time partition inner loop coil, a 3-time partition outer loop coil and a 2-time partition inner loop coil; the 10 radial coils are arranged in a staggered mode at 18 degrees, and each radial coil surrounds a 54-degree fan-shaped target surface.

Preferably, the magnetic induction coil assembly further comprises an invalid partition loop line, and the invalid partition loop line is arranged in the external annular frame.

The invention also protects the magnetic induction type electronic target based on the magnetic induction coil wiring structure.

The invention has the beneficial effects that: 1. the mesh-shaped bulges extending into the target body are arranged from the bottom plate in a breakthrough manner, but the wiring mode of the target surface structure is not influenced; 2. the cross section of the flaky bulge is wide at the bottom and narrow at the top, so that the flaky bulge can conveniently extend into the target body and is relatively fixed with the target body; 3. the length of the upper bottom is equal to the thickness of the knife line net, so that the effective scoring space of the target surface is ensured, and the dart drop rate is reduced; 4. the original wiring mode saves more than half of coil raw materials and also simplifies the wiring operation; 5. the magnetic induction coil of the invalid partition is additionally arranged, so that the manual treatment after the dart is thrown into the invalid partition is avoided.
