したがって、頂点位置を結んだ直径は、１６ｍｍ＜φ＜１７ｍｍであれば良い。なお、上記《１０》の《》記号は○を意味するものである。

つぎに（Ｂ）式および条件（ｉ）（ｉｉ）（ｉｉｉ）（ｉｖ）にしたがって図７（ａ）（ｂ）（ｃ）（ｄ）のＸ_ａ ， Ｘ_ｂ ， Ｘ_ｃ を決定する方法について説明する。
図７（ａ）において、Ｘ_ｎ ＜Ｗを考察すると、この式は条件 （ｉｉ） の前段に対応するものである。条件 （ｉｉ） の前段では例えば▲３▼▲５▼の集電子がギャップに落ちたときがギャップに最も多く集電子が落ちた場合であり、２つが接触する集電子は▲２▼▲６▼の集電子であり、▲３▼（▲５▼でも良い）の集電子からの最大寸法の集電子は▲２▼（▲５▼からは▲６▼となる）となる。したがってＸ_ａ は▲２▼と▲３▼を結ぶ距離となる。
図７（ｂ）（ｃ）（ｄ）についても同様にしてＸ_ａ を決定している。図７（ｂ）の場合には例えば▲３▼▲６▼の２つの集電子が落ちたとき、図７（ｃ）は例えば▲３▼▲９▼▲７▼の３つの集電子が落ちたとき、図７（ｄ）は例えば▲５▼▲６▼の２つの集電子が落ちたときがギャップに最も多く集電子が落ちた場合である。
【００２７】
図７（ａ）において条件 （ｉｉ） の中段では（Ｗ＋２ｔ）以上のときＸ_ｎ はＸ_ｂ と定義し、Ｘ_ｎ がＷより大きい場合には、▲２▼▲４▼の距離をＸ_ｂ とおけば、Ｘ_ｂ が（Ｗ＋２ｔ）以上であればそれぞれの帯状電極に常に接触する集電子が２以上になる。よってＸ_ｂ は▲２▼▲４▼の距離である。図７（ｂ）（ｃ）（ｄ）も同様にして決定している。
図７（ａ）において条件 （ｉｉ） の後段では（２Ｗ＋ｔ）以下のときＸ_ｎ はＸ_ｃ と定義し、Ｘ_ｎ がＷより大きい場合には、▲１▼▲４▼の距離をＸ_ｃ とおけば、Ｘ_ｃ が（２Ｗ＋ｔ）以下であればそれぞれの帯状電極に常に接触する集電子が２以上になる。よってＸ_ｃ は▲１▼▲４▼の距離である。図７（ｂ）（ｃ）（ｄ）も同様にして決定している。
【００２８】
図８は、集電子と移動体電極端子との接続構造を示す図である。
それぞれの集電子の出力は、それぞれ電流方向が逆方向の２つのダイオードに接続され、このダイオードの正方向同士の出力線を１つにまとめて陽極とし、ダイオードの逆方向同士の出力線を１つにまとめて陰極とし、移動体側に電力が供給される。
このように接続してあるので、移動体が移動して集電子の接触する帯状電極が変わっても極性が変化することなく常に移動体の陽極側には＋電位が、陰極側には−電位が接続される。
各ダイオードはまた給電板上の陽極と陰極が短絡しないようにする機能も兼ねている。さらに、このダイオード回路は整流であるため、給電板に供給する電圧は直流，交流のいずれを接続しても良い。
【００２９】
【発明の効果】
以上、説明したように本発明は、従来例とは異なり、給電板を絶縁板と導電層を交互に積層して構成し、導電層の少なくとも１つを陽極配電体に、他の少なくとも１つを陰極配電体とし、これらを介して帯状電極に電力を供給する構成であるので、配電ルートにおける電気抵抗が低くなり、配電ルートにおける無用な電力消費を少なくすることができるとともに、各移動体への電力供給をほぼ等しくすることができる。例えば、最低限の積層構造にした場合、すなわち陽極配電体と陰極配電体をそれぞれ１面ずつ占有した場合、電気抵抗は従来例に比べおおよそ１／３に抑えることができた。
また、主に陽極配電体，陰極配電体によって電力供給するため、帯状電極の厚みを薄くすることができるので、集電子の電極乗り越え段差を小さくし集電子の摺動の抵抗を少なくでき移動体を円滑に走行させることができる。
【００３０】
さらに、複数の給電板を並べてフィールド内に設置する場合であって半円状のコーナー部の給電板を複数に分割するとき、導電層を４層以上とし、表および裏の表面層を帯状電極にし一方の帯状電極側の透視方向から見た他の帯状電極の形状を同一にすれば、１種類の給電板を２枚使用し、この内の１枚を裏返しで対象の位置に配置することができ給電板の共通部品化を図ることができ、コストの低減および部品管理が容易になるという効果がある。
また、多積層構造であるので、従来例に比較し反り，ゆがみは少なく、剛性も増加し、移動体への安定な電力供給に寄与できる。
【００３１】
本発明は、移動体の姿勢がいかなる場合でも集電子条件が等しくなる正多角形の頂点位置または頂点位置と中心位置に集電子を設け、１番過酷な状態、すなわち複数の集電子が帯状電極間の１ギャップ上にあり給電できない状態でも、帯状電極の陽極および陰極にそれぞれが予め決められた数以上の集電子が接触し、この条件を必要最小限の集電子総数で実現できる構成にしてあるので、以下のような効果が得られる。
すなわち必要最小限の集電子数で、常に接触している集電子数を多くできるので、十分な接触を得ることでき、上記多積層構造の給電板と相まって移動体への電力供給を安定化できる。
【００３２】
そして、移動体が走行し、帯状電極の乗り越え段差あるいは給電板のつなぎ目段差では１，２本の集電子が引っかかり易くなるが、上述したように給電板の帯状電極を薄くしているので、段差部の乗り越え抵抗が少なくなる上、総合的に十分な接触抵抗を得られる程度に１本あたりの集電子の付勢圧を小さくすることができるので、集電子の引っかかりが少なくなり、移動体をスムーズに走行させることができるとともに集電子の磨耗も抑制され耐久性を向上させることができる。
また、最小の集電子数で常に接触している集電子数を多くし、十分な接触を得ているので、給電板の掃除期間を延長でき、メンテナンスが簡易になる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a power supply device for a game machine in which a moving object such as a model car or animal moves by receiving external power supply in a certain field.
[0002]
[Prior art]
In the above-mentioned game machine, a device for supplying power to a plurality of moving objects has been proposed (Japanese Utility Model Publication No. 5-11906).
In this device, strip electrodes are laid in a direction crossing the upper and lower surfaces of the insulating plate, and every other through hole is provided so that adjacent electrodes alternately become an anode and a cathode, and these are electrically connected. Thus, a single strip electrode is provided with a plurality of power supply points. The moving body is supplied with electric power by always bringing the current collector into contact with the strip electrode.
By adopting such a configuration, when a plurality of moving bodies run on the same strip-shaped electrode at the same time, the moving body located farther from the power supply unit (terminal electrode) is supplied with power by the power consumption of the intermediate moving body. To prevent the vehicle speed from becoming slower.
In other words, even if the current collectors of multiple moving objects are concentrated on the same electrode, almost the same power is always supplied from the power supply point with almost no influence of the distance difference between all the current collectors, enabling fair race development I have to.
[0003]
However, although this device has a plurality of power supply points, a separate power distribution route is not formed from a power supply unit to a plurality of moving objects, and a common power distribution route is formed. The power consumption in this common distribution route is determined by the electric resistance of the route. This is a configuration in which a band-shaped electrode on one side and a band-shaped electrode on the other side are connected to each other by a through hole, and a plurality of connection paths are connected in parallel. When traveling on the strip electrode, substantially the same power is always supplied from the power supply point, but actually there is still a considerable difference in the power supplied to each moving body.
[0004]
Further, the above-described device urges the contact of the current collector to the strip-shaped electrode in the direction of the strip-shaped electrode by a spring so as to maintain the contact even if some irregularities are generated on the power supply plate. Since the strip electrode and the current collector are slid, the contact resistance fluctuates greatly, making the supply voltage to the moving body unstable, and the moving body cannot run smoothly.
In order to alleviate this, a plurality of current collectors are arranged, and some current collectors are always in contact with each other so that any current collectors that did not make sufficient contact can be compensated for by any one of the current collectors. ing.
[0005]
[Problems to be solved by the invention]
However, increasing the total number of current collectors in order to increase the number of current collectors that are always in contact is due to the fact that the number of current collectors that do not function instantaneously increases, resulting in poor efficiency, and the energizing pressure for the total number of current collectors. The mechanical resistance rather increases and the moving body cannot run smoothly.
An object of the present invention is to solve the above-described problem. The power supply plate has an alternate multi-layered structure of an insulating plate and a conductive layer, and at least one of the stacked conductive layers is used as an anode power distribution body, and at least the other is used as a power supply plate. The power supply to each mobile unit is stabilized regardless of the position of the mobile unit by making the number of current collectors in contact with the anode and cathode as small as possible with the minimum total number of current collectors corresponding to the cathode power distribution unit. It is an object of the present invention to provide a power supply apparatus for a moving body which can obtain the same electric power and reduce a mechanical resistance to the movement of the moving body as much as possible to enable smooth running.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, a power supply apparatus for a moving object according to the present invention is provided above or below a field of a game machine to supply power to a moving object freely moving in a field of the game machine. A power supply plate formed on the surface layer with a strip-shaped electrode connected to a power supply so as to be mounted on each mobile body, and a large number of current collectors are pressed against the surface layer of the power supply plate as the mobile body moves. By being slid, in a power supply device including a current collector that supplies power to a moving body from the band-shaped electrode of the power supply plate, the power supply plate is configured by alternately stacking insulating plates and conductive layers, At least the conductive layer includes at least three layers including a surface layer, at least one of the conductive layers of the surface layer is a strip-shaped electrode repeatedly arranged in parallel at a predetermined interval, and at least one of the other conductive layers is Anode power distribution At least one of the other conductive layers is connected to a power source as a cathode power distribution, and the adjacent electrodes of the strip-shaped electrode are formed by a plurality of through-holes having a conductor on an inner wall so as to alternately become a cathode and an anode. Connected to the anode and cathode distributors.
[0007]
According to the above configuration, the power supply to each mobile unit is stabilized regardless of the position of the mobile unit, and each mobile unit can obtain the same power and reduce mechanical resistance as much as possible to the movement of the mobile unit, so that it is smooth. Running becomes possible.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in more detail with reference to the drawings.
FIG. 1 is an external perspective view of a game machine to which a power supply device for a moving object according to the present invention is applied. This example is a car racing game, a horse racing game, a boat racing game, or the like, in which a model body 2 such as a plurality of automobiles runs freely on an annular track and plays a game.
A plurality of terminals 3 are provided around the circular truck, and a monitor 7, an operation panel 4, a coin slot 5, and a coin payout port 6 are attached to this terminal 3. A game can be played by inserting coins, operating the operation panel 4 and voting on the model body 2 expected to win.
[0009]
FIG. 2 is a side view of a moving body provided with the power supply device according to the present invention.
A moving body 44 exists below the model body 2 via a truck, and the model body 2 and the moving body 44 are each provided with a magnet 25 in a direction of attracting each other and at a position slightly apart from the track. Have been.
The model body 2 itself has no power source, but the front wheel has one or more casters (or spherical wheels) 15, and the rear wheel has independent wheels 12 on the left and right sides, respectively, and the traveling body 44 provided with the power source travels. It follows the direction smoothly.
The truck has a three-layer structure, in which a game field 8 made of cloth is provided in an upper layer, a reinforcing plate 22 made of resin is provided in a middle layer, and a power supply plate 11 according to the present invention is provided in a lower layer.
[0010]
A traveling path 23 is laid below the power supply plate 11 through a space in which the moving body 44 travels. Under the traveling path 23, the XY coordinate positions are set at a constant interval in the front-rear and left-right directions or at equal angles in corners. A position transmitting plate 21 provided with a transmitting transmitter 20 is provided. Further, a reinforcing member 24 is laid down further below via a spacer.
The moving body 44 includes two steering / driving motors 17, infrared communication means (not shown), a position detector, a control device, a motor driver, and the like. One or more casters (or spherical wheels) 15, 19, Two sets of running means each including left and right independent wheels 13 and 18 are provided at the rear.
[0011]
The two sets of traveling means are arranged in the directions in which the wheels contact the ceiling surface and the floor surface, respectively, and there are parallel links 16 having compression elasticity by a torsion spring 26 therebetween. As a result, the moving body travel space is pressurized in the vertical direction, and the vibration of the moving body in the front-rear direction is suppressed, so that the moving body can travel smoothly.
The lower rear wheel 18 is driven by being gear-coupled to a steering / drive motor 17, but the two motors drive left and right separate wheels, respectively, and can change the rotation ratio to freely steer. I have.
A current collector 9 on which a plurality of current collectors 10 according to the present invention are arranged is fixed to the wheel fixing member of the upper traveling means in a direction protruding upward, and the current collector 9 is moved by the contact of the strip-shaped electrode on the power supply plate 11 with the current collector 9. Power is supplied to the body 44.
[0012]
In addition, regarding the traveling control of the moving body 44, the game machine body needs to reach a set of coordinate data in a fixed time unit from the start to the goal (that is, arrive at the X and Y coordinates a few minutes later) by the infrared communication means. (Speed and course data) to the mobile unit 44. The moving body 44 drives the steering / drive motor 17 based on the received signal, but detects the transmission signal of the transmitter 20 on the traveling path 23 via the position detector and feeds it back to the control device. Is running on a predetermined course at a predetermined speed.
[0013]
FIG. 3A is a cross-sectional view illustrating an example of a laminated structure of a power supply plate, and FIG. 3B is a cross-sectional view along AA ′. This example is realized by a manufacturing process of a four-layer substrate, in which three insulating plates 37 and four conductive layers are alternately stacked so that the conductive layer becomes a skin layer.
On one surface of the skin conductive layer, a cathode terminal electrode 34 and an anode terminal electrode 35 for connection to a power source are arranged at positions where the electric wires can be easily pulled out, and on the other surface, a band-shaped electrode (anode) 33 having a width W and a band-shaped electrode. Electrodes (cathodes) 36 are arranged in parallel at an interval t.
A plurality of holes 32 penetrating the power supply plate 11 are provided at predetermined positions of the strip-shaped electrode (anode) 33, the strip-shaped electrode (cathode) 36, the cathode terminal electrode 34, and the anode terminal electrode 35.
[0014]
The through hole 32 is generally called a via hole, and a conductor 38 is formed on the inner wall of the hole having an extremely small diameter. The through hole 32 is provided between the strip electrode (anode) 33 and the anode terminal electrode 35 and between the strip electrode (cathode) 36 and the cathode. The terminal electrodes 34 are electrically connected to each other.
Since the diameter of the contact surface of the current collector 10 is larger than the inner diameter of the through hole 32, the current collector 10 can smoothly pass through the through hole 32 with respect to sliding.
The inner conductive layer is not connected such that adjacent electrodes of the strip-shaped electrode are alternately connected to different polar layers by the through-holes 32 and the cathode terminal electrode 34 and the anode terminal electrode 35 are connected to different polar layers. Gaps 30a and 31a for insulation are provided in the through holes of the conductive layer. Therefore, one of the inner conductive layers serves as the cathode distributor 31 and the other serves as the anode distributor 30, and the adjacent strip electrodes (cathode) 36 and adjacent strip electrodes (anode) 33 are alternately arranged. become.
[0015]
In the example of FIG. 3, the through hole for connecting to the terminal electrode also serves as the through hole for connecting to the strip electrode, but a different through hole may be used.
In this example, one through hole for connecting to the terminal electrode is shown, but a plurality of through holes may be used. Further, although the terminal electrode is provided on a surface different from that of the strip electrode, an electric wire may be directly connected to the strip electrode.
When a plurality of power supply plates are arranged side by side in a field, by setting the dimension from the edge of the power supply plate to the band-shaped electrode to (1/2) t, when the plurality of power supply plates are connected to each other, the interval that can be connected is increased. t.
Similarly, in the case where a plurality of power supply plates are arranged side by side and the power supply plate to be installed in a place such as a corner portion in FIG. 1 is divided into a plurality of power supply plates, the two surface layers of the power supply plate are band-shaped electrodes, By seeing the other strip electrode in the perspective direction from the strip electrode, by arranging the same, the two feed plates are used, and one of them is turned upside down and the strip electrode is linearly arranged at a symmetrical position. With such arrangement, one power supply plate can also serve as two power supply plates.
[0016]
In addition, the thickness and the number of layers of the power distribution body can be changed as needed.
Even if the power supply plate is slightly warped or distorted, the contact with the band-shaped electrode can be maintained by the biasing pressure of the current collector, but the warpage and distortion become severe (the current collector determined to be durable together with severe warpage and distortion). In order to maintain the contact even if the head is worn, the current collecting movement stroke has a huge size, and if this stroke is set to an appropriate value, the contact cannot be maintained. Therefore, a situation in which power supply is cut off may occur, and the power supply plate must be kept as flat as possible.
However, according to the present invention, since two or more continuous conductive layers are laminated, warpage and distortion due to a temperature difference can be prevented and rigidity is high, so that the conductive layer can be used as it is as a ceiling surface or a floor surface.
[0017]
FIG. 4 is a side view showing the structure of the current collector.
The current collector 10 has a tip 10a in a hemispherical cylindrical shape, and has flanges 10b and 10c formed on the upper and lower portions. A compression spring 41 is interposed between the upper flange 10b and the collector support 40, and the tip 10a of the collector is brought into contact with the power supply plate 11 at an appropriate pressure.
As a result, even if the power supply plate 11 has some irregularities, the contact is always maintained, and a small contact resistance is realized, so that stable power is supplied to the moving body. The lower flange 10c functions as a stopper.
[0018]
In general, the strip electrode needs to have a cross-sectional area through which a necessary current can flow, and a step between the strip electrode and the gap between the electrodes is generated to some extent. In addition, since the maximum size of one power supply plate is limited in terms of processing, a plurality of power supply plates may be connected to form one field, and this connection step also occurs to some extent. Therefore, when the moving body travels and gets over these steps, one or two current collectors are easily caught by the urging pressure of the current collector.
However, since the power is mainly supplied to the strip electrode from the anode power distribution and the cathode power distribution by the structure of the power supply plate, the thickness of the strip power can be reduced. In addition, as described below, the number of current collectors that are always in contact with the minimum required number of current collectors is increased, and the energizing pressure of each current collector is sufficient to obtain sufficient contact resistance overall. Is reduced, so that the current collector can be prevented from being caught.
[0019]
FIG. 5 is a diagram for explaining a contact state between the band electrode of the power supply plate and the current collector.
As shown in FIG. 5, the current collector arranges the current collector 10 at a vertex position or a vertex position and a center position of a regular polygon having a predetermined diameter, and satisfies predetermined formulas and conditions so that the moving body 44 can move in any direction. Even when the vehicle runs, a predetermined number or more of the current collectors 10 always contact the strip electrodes 33 and 36 with the minimum number of current collectors required.
The above-mentioned predetermined diameter means the width of the strip-shaped electrode as W, the gap between the strip-shaped electrodes as t, and the dimension from a straight line connecting a plurality of current collectors to an arbitrary current collector orthogonal to the straight line. _n And m is the number of strip electrodes included within a predetermined diameter,
m (W + t) -t <X _n When <m (W + t) + t (A), the current collector is on one gap between the strip-shaped electrodes and power cannot be supplied, and is determined by arranging the current collector at a position other than the case where the expression (A) is satisfied. You. However, even if this condition is not satisfied, this does not apply when another current collector can be contacted.
[0020]
In order to satisfy the condition that each of the anode and the cathode of the strip-shaped electrode is in contact with a predetermined number or more of current collectors, and to configure this condition with the minimum necessary number of current collectors, X _n > 2W + 3t, power can be supplied, but at the vertex position of the regular polygon having the minimum angle, W> X _n Is not satisfied because the condition is not satisfied. That is, m = 3 or more is out of the condition. Therefore, substituting m = 1, 2 into equation (A) gives:
(Equation 1)
W <X _n <W + 2t ... (A) '
2W + t <X _n <2W + 3t ... (A) ",
The positions avoiding the positions where the expressions (A) ′ and (A) ″ hold are represented by the following expressions.
X _n <W, W + 2t <X _n <2W + t (B)
The relationship at this time is shown in FIG.
[0021]
However, the following conditions must be satisfied.
Condition (i) The minimum number of current collectors must be equal to or greater than the number of constant contacts between the two poles plus the number of current collectors arranged on the gap.
Condition (ii) X less than W value _n (X _n <W) is X _a And this X _a Is the dimension between the current collectors falling in the gap when the number of current collectors falling in the gap between charging is the largest and the current collectors in contact with the current collectors reaching a predetermined number, And X _n Determined by the largest dimension of
X of (W + 2t) or more _n (W + 2t <X _n ) Is X _b And X of (2W + t) or less _n (X _n <2W + t) is X _c Is defined.
Condition (iii) If the predetermined number of current collectors that are always in contact with each strip electrode is an odd number, one current collector is added to the center position.
Condition (iv) Except when another current collector can be contacted when the above equation (B) is not satisfied.
[0022]
FIG. 7 is a diagram illustrating an example of a specific calculation result.
FIGS. 7A and 7B are examples in which at least two or more current collectors always contact the anode strip electrode and the cathode strip electrode, respectively.
Assuming that the width of the strip-shaped electrode is W = 8 mm and the interval between the electrodes is t = 1 mm, the minimum angle (two current collectors) is obtained when the current collectors are arranged at the apexes of a regular hexagon as shown in FIG. When the electrons fall into the gap, two current collectors need to be in contact with each of the anode strip electrode and the cathode strip electrode, and 2 + 4 = hexagon), and the diameter connecting the apex positions is calculated by the following formula. You can ask.

Therefore, the diameter connecting the vertices of the regular hexagon may be 13.3 mm <φ <16 mm. In such a case, if the interval between the electrodes is 2 mm instead of 1 mm, then 16 mm <φ <16 mm, the answer is inconsistent, and a diameter that satisfies the above equation cannot be obtained, and is ignored in this case.
[0023]
Next, when the width of the strip-shaped electrode is W = 8 mm and the interval between the electrodes is t = 2 mm, the minimum angle is obtained when the current collector is arranged at the vertex position of a regular heptagon as shown in FIG. If W = 8 mm and t = 2 mm in FIG. 7 (a), the answers are inconsistent, so a regular hexagon does not hold and a heptagon with a large number of squares becomes the minimum square number. The diameter connecting the apex positions can be obtained by the following formula.
[Equation 3]
X _a <W ... (4)
X _b > W + 2t (5)
X _c <2W + t (6)
If the diameter of a circle forming a regular heptagon is φ,

Therefore, the diameter connecting the apex positions may be 14.8 mm <φ <18.9 mm.
[0024]
FIGS. 7C and 7D are examples in which at least three current collectors always contact the anode and the cathode, respectively.
Assuming that the width of the strip-shaped electrode is W = 8 mm and the interval between the electrodes is t = 1 mm, the minimum angle (when the current collector is arranged at the vertex position and the center position of the regular octagon as shown in FIG. Since the number of contacts is an odd number, if there is a current collector at the center position according to the condition (iii), and three gaps including the center position are dropped, such as a regular hexagon, three points are applied to the anode strip electrode and the cathode strip electrode, respectively. It is necessary for the current collectors to come into contact with each other, which results in 2 + 6 = octagon), and the diameter connecting the apexes can be obtained by the following formula.
(Equation 4)
X _a <W… (7)
X _b > W + 2t (8)
X _c <2W + t (9)
Where X _c = 2X _a And X _c Since the condition of <2W holds, X _c <2W + t (9) is not calculated.
When the diameter of a circle forming a regular octagon is φ,

Therefore, the diameter connecting the apex positions may be 14.1 mm <φ <16 mm. In this case, if the interval between the electrodes is 2 mm instead of 1 mm, then 17 mm <φ <16 mm, the answer is inconsistent, and a diameter satisfying the above equation cannot be obtained, and is ignored in this case.
[0025]
Next, when the width of the strip-shaped electrode is W = 8 mm and the interval between the electrodes is t = 2 mm, as shown in FIG. (W = 8 mm and t = 2 mm in FIG. 7 (c), since the answers are inconsistent, a regular octagon does not hold, and a 9-sided polygon with one corner becomes the minimum corner) And the diameter connecting the apex positions can be obtained by the following formula.
(Equation 5)
X _a <W ... (10)
X _b > W + 2t (11)
X _c <2W + t (12)
Assuming that the diameter of a circle forming a regular octagon is φ,

Although the example of FIG. 7D is an example corresponding to the expression (A) ′, even if the dimension of C satisfies W ≦ C ≦ W + 2t, one of the band-shaped electrodes is (9) (1). There is no problem because the current collector of (2) comes in contact with the current collector of (10), (7) and (4) on the other strip electrode. Even if the dimension of D satisfies W ≦ D ≦ W + 2t, the current collector of (1), (6) and (5) is applied to one of the strip electrodes, and (8), (10) and (3) of the other strip electrode. There is no problem because the current collector contacts. This is an example corresponding to the condition (iv), ie, (3) to (8) for the current collector of (6), (5), and (2) to (9) for the current collector of (4) and (7). (B) excludes the application of the formula (B).
Therefore, the diameter connecting the apex positions may be 16 mm <φ <17 mm. The symbol <<>> in the above << 10 >> means ○.
[0026]
Next, according to the formula (B) and the conditions (i), (ii), (iii), and (iv), X in FIGS. _a , X _b , X _c Will be described.
In FIG. 7A, X _n Considering <W, this equation corresponds to the former stage of condition (ii). In the preceding stage of the condition (ii), for example, when the current collectors of (3) and (5) fall into the gap, the most current collectors fall in the gap. The two current collectors contact (2) and (6). The current collector having the maximum size from the current collector of (3) (or (5)) is (2) (from (5) to (6)). Therefore X _a Is the distance connecting (2) and (3).
7 (b), (c), and (d), X _a Is determined. In the case of FIG. 7 (b), for example, when two current collectors of (3) and (6) fall, FIG. 7 (c) shows, for example, three current collectors of (3), (9) and (7) fall FIG. 7D shows a case where two current collectors (5) and (6) fall, for example, in the gap most frequently.
[0027]
In FIG. 7A, in the middle stage of the condition (ii), when (W + 2t) or more, X _n Is X _b And X _n Is larger than W, the distance of (2) and (4) is X _b If you go, X _b Is equal to or more than (W + 2t), the number of current collectors constantly in contact with each strip electrode is two or more. Therefore X _b Is the distance of (2) and (4). 7B, 7C, and 7D are determined in the same manner.
In FIG. 7A, in the subsequent stage of the condition (ii), X is equal to or less than (2W + t). _n Is X _c And X _n Is greater than W, the distance of (1) and (4) is _c If you go, X _c Is less than or equal to (2W + t), there are two or more current collectors constantly in contact with each strip electrode. Therefore X _c Is the distance of (1) and (4). 7B, 7C, and 7D are determined in the same manner.
[0028]
FIG. 8 is a diagram showing a connection structure between a current collector and a mobile electrode terminal.
The output of each current collector is connected to two diodes whose current directions are opposite to each other, and the output lines of the diodes in the positive direction are combined into one anode, and the output lines of the diodes in the opposite direction are connected to one another. Power is supplied to the moving body side as a cathode.
Since the connection is made in this way, even if the moving body moves and the strip-shaped electrode with which the current collector contacts changes, the polarity does not change and the positive potential is always applied to the anode side of the moving body and the negative potential is applied to the cathode side. Is connected.
Each diode also has a function of preventing a short circuit between the anode and the cathode on the power supply plate. Furthermore, since this diode circuit is rectified, the voltage supplied to the power supply plate may be either DC or AC.
[0029]
【The invention's effect】
As described above, the present invention is different from the conventional example in that the power supply plate is configured by alternately stacking the insulating plate and the conductive layer, and at least one of the conductive layers is provided on the anode power distribution body and at least one of the other is provided. Is a cathode power distribution body, and power is supplied to the strip-shaped electrodes through these, so that the electric resistance in the power distribution route is reduced, and unnecessary power consumption in the power distribution route can be reduced. Can be made almost equal. For example, in the case of the minimum laminated structure, that is, in the case where one surface of each of the anode power distribution and the cathode power distribution is occupied, the electric resistance can be reduced to about 1/3 as compared with the conventional example.
In addition, since power is supplied mainly by the anode and cathode power distribution bodies, the thickness of the strip-shaped electrodes can be reduced, so that the steps of the current collectors passing over the electrodes can be reduced and the resistance of the current collectors to sliding can be reduced. Can run smoothly.
[0030]
Furthermore, in the case where a plurality of power supply plates are arranged side by side in a field and the power supply plate at the semicircular corner portion is divided into a plurality of portions, the conductive layer is made to be four or more, and the front and rear surface layers are band-shaped electrodes. If the shape of the other strip electrode is the same as seen from the perspective direction of one strip electrode side, two types of power supply plates are used, and one of these is turned upside down and placed at the target position. Thus, the power supply plate can be used as a common component, which has the effect of reducing costs and facilitating component management.
In addition, because of the multi-layer structure, warpage and distortion are small and rigidity is increased as compared with the conventional example, thereby contributing to stable power supply to the moving body.
[0031]
The present invention provides a current collector at a vertex position or a vertex position and a center position of a regular polygon in which the current collection conditions are equal regardless of the posture of the moving body, and the most severe state, that is, a plurality of current collectors is a strip electrode Even if power cannot be supplied due to being on one gap between them, a predetermined number or more of current collectors are brought into contact with the anode and the cathode of the strip-shaped electrode, respectively. Therefore, the following effects can be obtained.
That is, since the number of current collectors that are always in contact can be increased with the minimum number of current collectors, sufficient contact can be obtained, and power supply to the moving body can be stabilized in combination with the power supply plate having the multi-layer structure. .
[0032]
Then, the moving body travels, and one or two current collectors are apt to be caught at a step over the strip-shaped electrode or at a joint at the feed plate. However, as described above, the step-shaped electrode of the feed plate is made thin, In addition to reducing the crossover resistance of the part, the energizing pressure of the current collector per one can be reduced to the extent that a sufficient contact resistance can be obtained comprehensively. The vehicle can run smoothly, and wear of the current collector can be suppressed to improve durability.
In addition, since the number of current collectors that are always in contact with the minimum number of current collectors is increased and sufficient contact is obtained, the cleaning period of the power supply plate can be extended and maintenance can be simplified.
